FIELD
The present invention relates to the technical field of environmental cleaning appliances, and specifically to a synchronized multidirectional movement mechanism for a cleaning tool and a cleaning tool provided with the mechanism.
BACKGROUND
Environmental cleaning appliances on the market generally have a single function, for example, cleaning appliances that only have the function of wiping, or cleaning appliances that only have the function of sweeping, or cleaning appliances that only have the function of scraping off the surface of objects. However, daily cleaning work often involves multiple cleaning needs, resulting in the need to carry two to three types of cleaning tools at the same time when carrying out daily cleaning work, which increases the burden of cleaning work.
Although some cleaning appliances are equipped with two or more sets of cleaning heads, the relative positions between these cleaning heads and the mounting base and operating rod on which the cleaning heads are installed are fixed. When the user holds the operating rod to use the cleaning heads, this not only results in a fixed orientation for cleaning of the cleaning heads, but also makes the commonly used cleaning tools take up more space when they are not in use.
SUMMARY
As a result, a general cleaning tool has a single function, resulting in the need to carry two to three cleaning tools at the same time, which increases the burden of cleaning work. Also, because the relative positions of the cleaning heads to both the mounting base and operating rod on which the cleaning heads are installed are fixed, when the user holds the operating rod to use the cleaning heads, this not only results in a fixed orientation for cleaning of the cleaning heads, but also makes the cleaning tools take up more space when they are not in use. In order to solve at least one of these problems, according to an aspect of the present invention, a synchronized multidirectional movement mechanism for a cleaning tool is provided.
The synchronized multidirectional movement mechanism for a cleaning tool comprises at least one set of movement units; and a drive module for driving all the movement units; wherein all the movement units are configured to be capable of driving, driven by the drive module, cleaning heads disposed thereon to reciprocate in different directions between a first position corresponding to the cleaning heads in an operating state and a second position corresponding to the cleaning heads in a non-operating state.
According to another aspect of the present invention, a cleaning tool is provided, which comprises the above-mentioned synchronized multidirectional movement mechanism for a cleaning tool, and further comprises an transfer block connecting a first rod and pivotally disposed on the mounting base about a first rotation shaft by means of at least one set of pivotal connecting units having a locking structure, wherein the locking structure is configured to be capable of locking at least the transfer block rotated relative to the mounting base by a first angle and by a second angle relative to the mounting base.
By providing at least one set of movement units, the present invention can avoid the need to carry more than two kinds of cleaning tools at the same time which increases the burden of cleaning work by disposing different cleaning heads with different cleaning functions on different movement units on the mounting base of the cleaning tool. At the same time, different movement units can separately drive the cleaning heads located thereon to switch between the operating state and the non-operating state, so that the cleaning heads can be driven by the movement units to a relatively compact position with the mounting base when in a non-use state, reducing the space occupied by the cleaning tool using the synchronized multidirectional movement mechanism when it is in the non-use state. Furthermore, since a plurality of sets of movement units can be driven by a single drive module, the synchronized multidirectional movement mechanism can be operated easily.

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be described clearly and completely in the following in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are a part of the embodiments of the present invention and not all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person of ordinary skill in the art without making creative work fall within the scope of protection of the present invention.
FIGS. 1 to 16 schematically show a synchronized multidirectional movement mechanism for a cleaning tool according to five embodiments of the present invention.
As shown in FIGS. 1, 4, and 5, the synchronized multidirectional movement mechanism for a cleaning tool includes at least one set of movement units 40 and a drive module 50. The drive module 50 is used to drive all the movement units 40 to move. All of the movement units 40 are configured to drive, driven by the drive module 50, cleaning heads 30 disposed on the movement units 40 to move in different directions (as shown in FIG. 1, along a first direction X and a second direction X′, respectively), i.e., reciprocating between a first position corresponding to the cleaning heads 30 in an operating state (as shown in FIG. 4) and a second position corresponding to the heads 30 in a non-operating state (as shown in FIG. 5). When there is a plurality of sets of cleaning heads 30, these cleaning heads 30 are differentiated, for example, by serial numbers, for case of differentiation, as a first cleaning portion 31, a second cleaning portion 32, a third cleaning portion 33, etc., and so on.
By providing at least one set of movement units 40, the present invention can realize that cleaning heads 30 that can perform different cleaning functions are respectively provided on at least one set of movement units 40 on the mounting base 20 of the cleaning tool, so as to avoid increasing the burden of cleaning work due to the need of carrying more than two cleaning tools at the same time. Meawhile, each set of movement units 40 can separately drive the cleaning heads 30 disposed thereon to switch between the operating state (as shown in FIGS. 1, 2, 4, and 15) and the non-operating state (as shown in FIGS. 5 and 12), so that the cleaning head 30, when in the non-operating state, can be driven by the corresponding movement unit 40 to the desired position, thus making the overall structure relatively compact and reduce the space occupied by the cleaning tool using the synchronized multidirectional movement mechanism in the non-operational state. Moreover, the embodiment of the present invention can drive more than one set of movement units 40 by one drive module 50, making the operation of the synchronized multidirectional movement mechanism very convenient.
In order to enable users to use at least two cleaning heads 30 simultaneously when using a cleaning tool provided with the synchronized multidirectional movement mechanism, in some preferred embodiments, at least two different cleaning heads 30 are configured so that they are located on different sides of the mounting base 20 when in the operating state. Taking an example of having three cleaning heads 30, the first cleaning portion 31 has a wiping function, e.g., the first cleaning portion 31 is a mop; the second cleaning portion 32 has a sweeping function, e.g., the second cleaning portion 32 is a duster; and the third cleaning portion 33 has a function of scraping away adherents on the surface of an object, e.g., the third cleaning portion 33 is a scraping body, made of, e.g., a soft, rubbery material, or made of a hard metal material. As shown in FIGS. 1 and 2, the first cleaning portion 31, the second cleaning portion 32, and the third cleaning portion 33 provided on the mounting base 20 have respective operating states, and at least two of the first cleaning portion 31, the second cleaning portion 32, and the third cleaning portion 33 are configured so that they are located on different sides of the mounting base 20 when in the operating state. For example, the first cleaning portion 31 is disposed on a first side 21 of the mounting base 20 when it is in the operating state, the second cleaning portion 32 is disposed on a second side 22 of the mounting base 20 when it is in the operating state, and the third cleaning portion 33 is disposed on a bottom side 26 of the mounting base 20 when it is in the operating state (as shown in FIGS. 1 and 2).
As an embodiment of the drive module 50, as shown in FIG. 4, the drive module 50 comprises a drive unit 51 and a transmission unit 52. The drive unit 51 is capable of driving all the movement units 40 through the transmission unit 52, thereby driving the cleaning heads 30 disposed on the corresponding set of movement units 40 to perform reciprocating motion. As a preferred embodiment, the direction of movement of the cleaning heads 30 on the different movement units 40 is different. As a result, the cleaning heads 30 on at least two sets of the movement units 40 can be driven to reciprocate in different directions by one set of drive units 51 driving the transmission units 52, which is convenient for operation.
In some preferred embodiments, the drive unit 51 is configured to be able to drive all the movement units 40 simultaneously or not simultaneously by the transmission unit 52 to drive the cleaning heads 30 disposed thereon to reciprocate in different directions respectively. As a result, it is possible to drive all the movement units 40 simultaneously by the drive unit 51 driving the movement units 40 to drive the transmission unit 52, so as to improve the operational efficiency of the movement units 40.
In some preferred embodiments, the synchronized multidirectional movement mechanism further includes the mounting base 20 and a locking module 53. The drive unit 51 is disposed on the mounting base 20. The locking module 53 is capable of locking the drive unit 51, the movement unit 40, or the transmission unit 52 corresponding to the cleaning head 30 in the first position relative to the mounting base 20, and/or, the locking module 53 is capable of locking the drive unit 51, the movement unit 40, or the transmission unit 52 corresponding to the cleaning head 30 in the second position relative to the mounting base 20. That is, by locking the movement unit 40 in the first position relative to the mounting base 20 by the locking module 53, the stability of the movement unit 40 in the operating state is improved. The stability of the movement unit 40 in the non-operating state is improved by means of the locking module 53 locking the movement unit 40 in the second position relative to the mounting base 20.
In some embodiments, as shown in FIGS. 1, 4, and 6, the mounting base 20 may be provided with a reinforcing plate 2013 therein, which has a recessed groove 2014 recessively molded at an end thereof, and the transmission unit 52 moves over the recessed groove 2014. As a result, the overall structural strength of the cleaning tool can be improved by the reinforcing plate 2013. The design of the recessed groove 2014 can also avoid disengagement of the transmission unit 52 due to up and down shaking during operation.
In some embodiments, as shown in FIGS. 1, 4, and 6, the drive unit 51 may be provided with a guiding groove 513 thereon, and the mounting base 20 is provided with a guiding bump 2015 thereon. The guiding groove 513 is fitted over the guiding bump 2015, and both are provided along the direction of movement of the drive unit 51. As a result, the movement of the drive unit 51 can be better guided by adding the guiding groove 513 and the guiding bump 2015. Further, as a preferred embodiment, the guiding groove 513 may have side flaps 5131 extending downwardly on both sides thereof. When the drive unit 51 is provided on the mounting base 20, the two side flaps 5131 are on both sides of the guiding bumps 2015. The lower end surfaces of the two side flaps 5131 abut against the inner wall of the mounting base 20 and support the drive unit 51. Thereby, the drive unit 51 can be supported by the side flaps 5131, thereby reducing the friction between the drive unit 51 and the inner wall of the mounting base 20.
As an embodiment of the locking module 53, the locking module 53 includes a snap-fitting structure 5301 and a slot structure 5302 capable of snap-fit connection. At least one of the snap-fitting structure 5301 and the slot structure 5302 is provided on the mounting base 20, and at least the other one is provided on the drive unit 51. Alternatively, at least one of the snap-fitting structure 5301 and the slot structure 5302 is provided on the mounting base 20, and at least the other one is provided on the drive unit 52. Alternatively, at least one of the snap-fitting structure 5301 and the slot structure 5302 is provided on the mounting base 20, and at least the other one is provided on the movement unit 40. When it is necessary to unlock the drive unit 51, the movement unit 40 or the transmission unit 52 from the mounting base 20, it is only necessary to separate the snap and the slot that are snap-fitted together with each other. With the locking mechanism of the present invention, no external tools are required in both the locking and unlocking process, and the operation is convenient.
In some embodiments, at least two sets of the transmission units 52 are provided. The drive unit 51 drives each set of transmission units 52 to individually move a set of movement units 40. The transmission unit 52 includes at least one set of rotating mechanisms 52110 and at least two sets of sequentially disposed moving mechanisms 52120. The drive unit 51 is configured to be able to drive the rotating mechanisms 52110 to rotate, which in turn drives the two sets of sequentially disposed moving mechanisms 52120 to move the movement units 40.
The specific structure of the present invention is exemplarily described below in connection with specific embodiments.
Embodiment 1
As shown in FIGS. 1 to 7, the synchronized multidirectional movement mechanism for a cleaning tool of the present embodiment includes two sets of movement units 40, which are referred to as the first movement unit 41 and the second movement unit 42 for case of differentiation. The first movement unit 41 is configured to drive, driven by the drive module 50, the cleaning head 30 disposed on the first movement unit 41 to reciprocate in a first direction X between a first position corresponding to the cleaning head 30 in the operating state (shown in FIG. 4) and a second position corresponding to the cleaning head 30 in the non-operating state (shown in FIG. 5). The second movement unit 42 is configured to drive, driven by the drive module 50, the cleaning head 30 disposed on the second movement unit 42 to reciprocate in a second direction X′ between the first position corresponding to the cleaning head 30 in the operating state and the second position corresponding to the cleaning head 30 in the non-operating state.
By providing the first movement unit 41 and the second movement unit 42, the present embodiment can realize that cleaning heads 30 that can perform different cleaning functions are respectively provided on the first movement unit 41 and the second movement unit 42 of the mounting base 20 of the cleaning tool, so as to avoid increasing the burden of cleaning work due to the need to carry more than two cleaning tools at the same time. At the same time, the first movement unit 41 and the second movement unit 42 can respectively drive the cleaning heads 30 disposed thereon to reciprocate between the operating state and the non-operating state, so that the cleaning heads 30, when not in use, can be driven by the first movement unit 41 and the second movement unit 42 to a position relatively compact with respect to the structure of the mounting base 20 in order to reduce the space occupied by the cleaning too using the synchronized multidirectional movement mechanism when it is not in use. Since the first movement unit 41 and the second movement unit 42 can be driven by a single drive module 50, this makes the operation of the synchronized multidirectional movement mechanism more convenient. Preferably, as shown in FIGS. 4, 5 and 9, in order to realize that the cleaning heads 30 can be stowed away when not in use to ensure the compactness of the structure of the cleaning tool, two sets of cleaning heads 30 are provided, namely the first cleaning portion 31 and the second cleaning portion 32, for example. The first cleaning portion 31 is disposed on the first movement unit 41, and the second cleaning portion 32 is disposed on the second movement unit 42. Accordingly, the mounting base 20 is provided with a first holding chamber 201 having a first opening 202 and a second holding chamber 203 having a second opening 204. The first opening 202 and the second opening 204 are provided on surfaces on different sides of the mounting base 20. When in the first position, i.e., in the operating state, at least a portion of the first cleaning portion 31 extends from the first opening 202 to the exterior of the first holding chamber 201, and at least a portion of the second cleaning portion 32 extends from the second opening 204 to the exterior of the second holding chamber 203. When in the second position, i.e., in the non-operating state, the first cleaning portion 31 is located inside the first holding chamber 201, and the second cleaning portion 32 is located inside the second holding chamber 203. Further, to reduce the influence of the movement unit 40 from the outside, the movement units 40 are also provided in the first holding chamber 201 and the second holding chamber 203, as shown in FIGS. 4 and 5.
In some embodiments, two cleaning heads 30 are included as an example. As shown in FIGS. 3 to 5, the first movement unit 41 includes a first sliding block 411 fixedly disposed relative to the first cleaning portion 31 and a first sliding channel 412 fixedly disposed relative to the mounting base 20 and adapted to the first sliding block 411. The second movement unit 42 includes a second sliding block 421 fixedly disposed relative to the second cleaning portion 32 and a second sliding channel 422 fixedly disposed relative to the mounting base 20 and adapted to the second sliding block 421.
An embodiment of the transmission unit 52 is shown in FIGS. 4 to 7 and 11. The transmission unit 52 includes at least one set of rotating mechanisms 52110 and at least two sets of moving mechanisms 52120 disposed in sequence. The rotating mechanisms 52110 are connected to the two sets of moving mechanisms 52120 and the movement unit 40 in sequence. For example, the rotating mechanism 52110 is connected to a first set of moving mechanisms of the two sets of moving mechanisms 52120, and the first set of moving mechanisms is connected to a second set of moving mechanisms of the two sets of moving mechanisms 52120. The second set of moving mechanisms is connected to one of the sets of movement units 40, and the rotating mechanism 52110 is also connected to the drive unit 51. The drive unit 51 drives the rotating mechanism 52110 to rotate, the rotating mechanism 52110 drives the one set of moving mechanisms 52120 to move, and the set of moving mechanisms 52120 drives the other set of moving mechanisms 52120 to move while driving the corresponding movement unit 40 to move.
In the preferred embodiment, as shown in FIGS. 4 and 5, two set of the transmission units 52 are provided, referred to as a first transmission mechanism 521 and a second transmission mechanism 522, respectively. The drive unit 51 drives the first movement unit 41 via the first transmission mechanism 521 to drive the cleaning head 30 disposed on the first movement unit 41 to reciprocate in the first direction X. The drive unit 51 drives the second movement unit 42 via the second transmission mechanism 522 to drive the cleaning head 30 disposed on the second movement unit 42 to reciprocate in the second direction X′. Thus, by adjusting the setting method and setting position of the first transmission mechanism 521 and the second transmission mechanism 522, it is possible to realize that the first transmission mechanism 521 and the second transmission mechanism 522 drive the first movement unit 41 and the second movement unit 42 simultaneously or at different times under the drive of the drive unit 51.
Exemplarily, the first transmission mechanism 521 includes a first rotating mechanism 5211, a first moving mechanism a 5212, and a first moving mechanism b 5213 provided in sequence. The first rotating mechanism 5211 includes a first pivot shaft 52111 disposed on the drive unit 51 and a first rotation rod 52112 pivotable about the first pivot shaft 52111 relative to the drive unit 51. The first moving mechanism a 5212 includes a first sliding groove a 52121 integrally molded or machined on the first rotation rod 52112 and a first sliding post a 52122 adapted to the first sliding groove a 52121. The length direction of the first sliding groove a 52121 is perpendicular to the first pivot shaft 52111, and the first sliding post a 52122 is fixedly disposed with respect to the mounting base 20. The first moving mechanism b 5213 includes a first sliding post b 52132 integrally molded, machined, or connected to the first rotation rod 52112 and a first sliding groove b 52131 integrally molded, machined, or connected to the corresponding movement unit 40. The first sliding post b 52132 is adapted to the first sliding groove b 52131, and the length direction of the first sliding groove b 52131 is perpendicular to the first pivot shaft 52111. Exemplarily, the first sliding groove b 52131 is disposed on the first movement unit 41. Specifically, the first sliding groove b 52131 is fixedly disposed relative to the first sliding block 411.
Exemplarily, the second transmission mechanism 522 includes a second rotating mechanism 5221, a second moving mechanism a 5222, and a second moving mechanism b 5223 disposed in sequence. The second rotating mechanism 5221 includes a second pivot shaft 52211 disposed on the drive unit 51 and a second rotation rod 52212 pivotable about the second pivot shaft 52211 relative to the drive unit 51. The second moving mechanism a 5222 includes a second sliding groove a 52221 integrally molded or machined on the second rotation rod 52212 and a second sliding post a 52222 adapted to the second sliding groove a 52221. A length direction of the second sliding groove a 52221 is perpendicular to the second pivot shaft 52211, and the second sliding post a 52222 is fixedly disposed with respect to the mounting base 20. The second moving mechanism b 5223 includes a second sliding post b 52232 integrally molded, machined, or connected to the second rotation rod 52212 and a second sliding groove b 52231 integrally molded, machined, or connected to the corresponding movement unit 40. The second sliding post b 52232 is adapted to the second sliding groove b 52231, and the length direction of the second sliding groove b 52231 is perpendicular to the second pivot shaft 52211. Exemplarily, the second sliding groove b 52231 is disposed on the second movement unit 42. Specifically, the second sliding groove b 52231 is fixedly disposed relative to the second sliding block 421.
Preferably, the moving direction of the drive unit 51 is perpendicular to the first pivot shaft 52111. Through the movement of the drive unit 51, the rotating mechanism 52110 is driven to rotate, which in turn drives the moving mechanism 52120 to move, and at the same time drives the movement unit 40 to move. Preferably, as shown in FIG. 1, FIG. 2, FIG. 4 and FIG. 5, the first side 21 and the second side 22 of the mounting base 20 are located on two sides of the mounting base 20 that are opposite to each other, respectively, to minimize the first cleaning portion 31 and the second cleaning portion 32 from influencing each other in the operating state.
Referring to FIGS. 6 and 7, the recessed groove 2014 on the reinforcing plate 2013 is capable of supporting the moving mechanism 52120. Thereby, the overall structural strength of the cleaning tool can be improved by the reinforcing plate 2013. The design of the recessed groove 2014 can also avoid the occurrence of disengagement of the transmission unit 52 due to up and down shaking thereof during operation.
An embodiment of the drive unit 51 is shown in FIGS. 3 to 7. The drive unit 51 includes a slide block 511 and a first slide channel 512 adapted to the slide block 511. The first slide channel 512 is integrally molded or machined on the mounting base 20 and is provided along a third direction Y and a fourth direction Y to enable movement of the slide block 511 along the third direction Y and the fourth direction Y″. The first pivot shaft 52111 and the second pivot shaft 52211 are disposed on the slide block 511. The slide block 511 preferably has a first limit position corresponding to the cleaning head 30 in the first position (as shown in FIG. 4), and a second limit position corresponding to the cleaning head 30 in the second position (as shown in FIG. 5). The slide block 511 has a blocking block 5111, and the first slide channel 512 is provided with a blocking portion 5121. When the slide block 511 is in the limit position, the blocking block 5111 abuts against the blocking portion 5121 to prevent the slide block 511 from continuing to move in the direction in which it was originally moving through the blocking portion 5121. In some preferred embodiments, referring to FIGS. 3 to 5 again, in order to ensure that the slide block 511 can be stably in the first limit position and/or the second limit position, the locking module 53 includes a first locking mechanism 531 capable of locking the slide block 511 in the first limit position, and a second locking mechanism 532 capable of locking the slide block 511 in the second limit position. Correspondingly, the snap-fitting structure 5301 and the slot structure 5302 of the locking module 53 include a first snap 5311 and a first slot 5312 of the first locking mechanism 531, respectively, and the first slot 5312 and the first snap 5311 can be snap-fitted with each other when the slide block 511 is in the first limit position. One of the first slot 5312 and the first snap 5311 is disposed on the slide block 511, and the other is disposed on the mounting base 20. Correspondingly, the snap-fitting structure 5301 and the slot structure 5302 of the locking module 53 also include a second snap 5321 and a second slot 5322 of the second locking mechanism 532, respectively, which can be snap-fitted with each other when the slide block 511 is in the second limit position. One of the second slot 5322 and the second snap 5321 is disposed on the slide block 511, and the other is disposed on the mounting base 20. When both the first snap 5311 and the second snap 5321 are disposed on the slide block 511, the first snap 5311 and the second snap 5321 may be shared. That is, it is sufficient to provide only one snap. When the first slot 5312 and the second slot 5322 are both disposed on the slide block 511, the first slot 5312 and the second slot 5322 can be shared. That is, it is sufficient to provide only one slot. This simplifies the structure of the multifunctional cleaning tool for case of processing and manufacturing. In order to ensure the stability of the locking module 53 in locking the slide block 511 in the first limit position and the second limit position, as shown in FIG. 3, the locking module 53 also includes a third locking mechanism 533 capable of locking the slide block 511 in the first limit position and a fourth locking mechanism 534 capable of locking the slide block 511 in the second limit position. The third locking mechanism 533 and the first locking mechanism 531 are symmetrically arranged relative to the slide block 511, and the fourth locking mechanism 534 and the second locking mechanism 532 are symmetrically arranged relative to the slide block 511. Like the first locking mechanism 531 and the second locking mechanism 532, the third locking mechanism 533 includes a third slot 5332 and a third snap 5331 capable of snap-fit connection when the second movement unit 42 is in the first position. One of the third slot 5332 and the third snap 5331 is disposed on the slide block 511, and the other is disposed on the mounting base 20. The fourth locking mechanism 534 includes a fourth slot 5342 and a fourth snap 5341 capable of snap-fit connection when the second movement unit 42 is in the second position. One of the fourth slot 5342 and the fourth snap 5341 is disposed on the slide block 511, and the other is disposed on the mounting base 20. When both the third snap 5331 and the fourth snap 5341 are disposed on the slide block 511, the third snap 5331 and the fourth snap 5341 may be shared. That is, it is sufficient to provide only one snap. When the third slot 5332 and the fourth slot 5342 are both disposed on the slide block 511, the third slot 5332 and the fourth slot 5342 may be shared. That is, it is sufficient to provide only one slot. When it is necessary to unlock the first movement unit 41 and the second movement unit 42 from the mounting base 20, it is only necessary to separate the snap and slot that are snap-fitted together with each other. With the locking mechanism of the present invention, there is no need to use external tools in both the locking and unlocking process, and the operation is convenient. Preferably, as shown in FIGS. 3 to 5, to ensure the compactness of the structure of the multifunctional cleaning tool, the mounting base 20 is also integrally molded or machined with a third holding chamber 205 and third openings 206 that connect the third holding chamber 205 to the outside. The first slide channel 512 is disposed in the third holding chamber 205, and the slide block 511 can extend from the third opening 206. The third openings 206 are disposed on opposite sides of the mounting base 20, and at least a portion of the slide block 5111 is located on the outside of the third openings 206 to facilitate manipulation of the slide block 511 when the slide block 511 is in the limit position. The third openings 206 are preferably not disposed on the first side 21, the second side 22, a top surface (a fifth side 25), and a bottom surface 26 of the mounting base 20. As an example, two third openings 206 are located on the third side 23 and the fourth side 24 of the mounting base 20, respectively, so as not to interfere with other components. When the slide block 511 is in different limit positions, the blocking block 5111 preferably protrudes externally through the third openings 206 on different sides to allow an operator to manipulate the direction of movement of the slide block 511 by pushing. In some embodiments, the third holding chamber 205 is in communication with at least one of the first holding chamber 201 and the second holding chamber 203.
As shown in FIG. 6, the guiding groove 513 may be provided on the drive unit 51, the guiding bump 2015 is provided on the mounting base 20, with the guiding groove 513 being fitted over the guiding bump 2015. Both the guiding groove 513 and the guiding bump 2015 are provided along a direction of movement of the drive unit 51 (i.e., the third direction Y and the fourth direction Y). Specifically, the guiding groove 513 may be provided in the middle of the slide block 511, and the guiding bump 2015 may be provided in the middle of the first slide channel 512, with the length of the guiding bump 2015 being shorter than the length of the guiding groove 513 to guide the sliding of the slide block 511. Both sides of the guiding groove 513 may be provided with side flaps 5131 extending downwardly, and two side flaps 5131 are respectively provided on both sides of the guiding bump 2015, the lower end surfaces of which abut against the inner wall of the mounting base 20 and supporting the drive unit 51. Thereby, the drive unit 51 may be supported by the side flaps 5131 to reduce the friction force between the drive unit 51 and the inner wall of the mounting base 20.
In some preferred embodiments, as shown in FIGS. 1, 6, 7, 9, and 10, in order to facilitate the machining of the mounting base 20, the mounting base 20 includes a top plate 2011 and a bottom plate 2012 that are removably coupled, so that when the top plate 2011 and the bottom plate 2012 are coupled, at least one of the first holding chamber 201, the second holding chamber 203 and the third holding chamber 205 is enclosed therebetween.
In this embodiment, as shown in FIGS. 8 and 10, the synchronized multidirectional movement mechanism for a cleaning tool preferably further includes a drive switch 54 provided on the top surface (fifth side 25) of the mounting base 20, which is configured to be capable of driving the slide block 511 to move along the first slide channel 512 in the third direction Y or the fourth direction Y in response to an external pressure. When the external force applied to the drive switch 54 is removed, the drive switch 54 drives the slide block 511 to move in a reverse direction. Thus, manipulation of the drive unit 51 can be facilitated. The drive switch 54 includes, for example, a drive rod 542 pivotably disposed on the top surface of the mounting base 20 about the fourth pivot shaft 541. The drive rod 542 is pivotably disposed on the slide block 511 about the fifth pivot shaft 543, and the fourth pivot shaft 541 is parallel to the fifth pivot shaft 543 and perpendicular to the direction in which the slide block 511 move along the first slide channel 512. In some embodiments, the drive rod 542 is made of a material with elastic deformation capability. In other embodiments, the fourth pivot shaft 541 and the fifth pivot shaft 543 are provided with torsion springs capable of driving the drive rod 542 to rotate about the fourth pivot shaft 541 and the fifth pivot shaft 543.
In other implementations, the drive unit 51 may also be a cylinder or oil cylinder with a cylinder seat fixed relative to the mounting base 20. The first pivot shaft 52111 and the second pivot shaft 52211 are disposed on a piston rod of the cylinder or oil cylinder, and the piston rod is perpendicular to the first pivot shaft 52111. The drive unit 51 is configured to drive the rotating mechanism 52110 to rotate about a first central axis 55 perpendicular to the direction of movement of the movement unit 40.
Embodiment 2
The present embodiment can be obtained by modification on the basis of Embodiment 1, with the difference being mainly in the different realization of the transmission unit 52.
As another embodiment of the transmission unit 52, as shown in FIG. 11, in the two sets of moving mechanisms 52120 of the transmission unit 52, the moving mechanism 52120 for connecting with the movement unit 40 may be provided to be pressed against the movement unit 40 by the abutting portion 523. Driven by the drive unit 51, the movement unit 40 is pushed using the abutting portion 523 to move the cleaning head 30 mounted on the movement unit 40 from the second position in the non-operational state to the first position in the operational state. The transmission unit 52 also includes a fourth elastic member 524 provided on the mount 20, the ends of which are connected to the two movement units 40 or the two cleaning heads 30, respectively, so that the two movement units 40 cause the cleaning heads 30 mounted thereon to have a tendency to move to the second position of the non-operating state. In turn, under the action of the moving mechanism 52120 and the fourth elastic member 524, it is possible to realize driving the two cleaning heads 30 to reciprocate between the operating state and the non-operating state.
Embodiment 3
This embodiment can be obtained by modifying on the basis of Embodiment 1, and the difference therebetween mainly lies in the different realization of the transmission unit 52.
As shown in FIG. 12, in this embodiment, only one group of movement unit 40 is provided on the mounting base 20, so that the cleaning heads 30, which play different cleaning roles, can be controlled to move in different directions by providing only one group of movement unit 40. In this embodiment, the transmission unit 52 includes at least two groups of moving mechanisms 52120 disposed in sequence. For example, one group of the movement units 40 is connected to a first group of moving mechanisms which is connected to a second group of moving mechanisms, and the second group of moving mechanisms is connected to the drive unit 51. The drive unit 51 drives the first group of moving mechanisms 52120 to move, and the group of moving mechanisms drives the corresponding movement units 40 to move while driving the other group of moving mechanisms 52120 to move. Exemplarily, the first drive mechanism 521 includes a first moving mechanism a′ 5212′ and a first moving mechanism b′ 5213′. The first moving mechanism a′ 5212′ includes a first rack 52121′ disposed on the first slider 411 and extending in a moving direction of the first moving unit, and a first gear 52122′ adapted to the first rack 52121′. The first gear 52122′ is pivotably disposed on the mounting base 20. The first moving mechanism b′ 5213′ includes a second rack 52131′ adapted to the first gear 52122′, the second rack 52131′ being disposed perpendicular to the direction of extension of the first rack 52121′. The second rack 52131′ is disposed on the drive unit 51, for example on the slide block 511. As a result, the second rack 52131′ is driven by the drive unit 51 in the direction of extension of the second rack 52131′ to drive the first gear 52122′ to rotate, and at the same time the first rack 52121′ and the first slider block 411 are driven in the direction of extension of the first rack 52121′. Exemplarily, the second transmission mechanism 522 includes a second moving mechanism a′ 5222′ and a second moving mechanism b′ 5223′. The second moving mechanism a′ 5222′ includes a third rack 52221′ disposed on the second slider 421 and extending in the direction of movement of the second movement unit, and a second gear 52222′ adapted to the third rack 52221′ pivotally disposed on the mounting base 20. The second moving mechanism b′ 5223′ includes a fourth rack 52231′ adapted to the second gear 52222″, which is disposed perpendicular to the direction of extension of the third rack 52221′. The fourth rack 52231′ is disposed on the drive unit 51, for example on the slide block 511. As a result, the fourth rack 52231′ is driven by the drive unit 51 in the direction of extension thereof to drive the second gear 52222′ to rotate, and at the same time to drive the third rack 52221′ and the second slider 421 in the direction of extension of the third rack 52221′. Preferably, the second gear 52222′ may be shared with the first gear 52122′, as may the second rack 52131′ and the fourth rack 52231.
Embodiment 4
In this embodiment, the movement unit 40 is provided as a structure capable of rotating to drive the first cleaning portion 31, the second cleaning portion 32, or the third cleaning portion 33 connected thereto to reciprocate between the first position and the second position. Further, when the movement unit 40 drives two of the first cleaning portion 31, the second cleaning portion 32, and the third cleaning portion 33 to reciprocate between the first position and the second position, the movement unit 40 is provided with only two movement units, one of which is capable of driving one of the first cleaning portion 31, the second cleaning portion 32, and the third cleaning portion 33 to reciprocate between the first position and the second position, and another of which is capable of driving the other one to reciprocate between the first position and the second position. As a result, when the second cleaning portion 32 and the third cleaning portion 33 are not needed, the second cleaning portion 32 can be driven to flip over to cover the mount base 20 by the first rotation unit, and the third cleaning portion 33 can be driven to flip over to cover the mounting base 20 by the second rotation unit to ensure the compactness of the structure of the multifunctional cleaning tool in the non-use state. Further, when the movement unit 40 is capable of driving the first cleaning portion 31, the second cleaning portion 32 and the third cleaning portion 33 to reciprocate between the first position and the second position, one movement unit 40 is provided corresponding to each of the first cleaning portion 31, the second cleaning portion 32 and the third cleaning portion 33, respectively, and individually drives the corresponding cleaning head 30 to reciprocate between the first position and the second position, respectively. In this embodiment of the present invention, the rotating unit (including the first rotating unit, the second rotating unit and the third rotating unit) may adopt the structure of the rotating unit commonly used in the prior art, and the present invention is not limited thereto. As shown in FIGS. 13 and 14, the movement unit 40 drives the first cleaning portion 31 to reciprocate between the first position and the second position. The first cleaning portion 31 is connected to the movement unit 40, which is rotationally connected to the mounting base 20, and a first bevel gear 451 is provided at the end of its rotating shaft. a second bevel gear 452 is provided on the mounting base 20, and its rotating shaft is provided with a gear and engages with a rack provided on the drive unit 51. The drive unit 51 will drive the second bevel gear 452 to rotate when the drive unit 51 is in motion, and drive the movement unit 40 to turn over under the meshing of the second bevel gear 452 and the first bevel gear 451, to cause the first cleaning portion 31 to reciprocate between the first position and the second position.
In this embodiment, the drive module 50 may adopt a commonly used rack-and-pinion structure, whereby the movement of the rack drives the rotation of the gears engaged with the rack, which in turn drives the rotation unit disposed on the gears to drive the rotation of the cleaning portion.
Example 5
The present embodiment can be obtained by modification on the basis of Embodiment 1, and the difference therefrom mainly lies in the different realization of the transmission unit 52 and the drive unit 51. As shown in FIGS. 15 and 16, the transmission unit 52 is provided with at least one set including at least one set of rotation mechanisms 52110′ and at least two sets of moving mechanisms 52120. The drive unit 51 is set up so as to be able to drive the rotation mechanisms 52110′ to rotate, which in turn drives all of the moving mechanisms 52120 into motion, so as to drive the movement unit 40 into motion. In this embodiment, the rotation mechanism a 52110′ includes a turntable 52111′. The moving mechanism 52120 includes an arcuate slot 521111′ integrally molded or machined in the turntable 52111′, and a third sliding post 52112′ adapted to fit in the arcuate slot 521111′. The arcuate slot 521111′ is provided to increase or decrease in distance from the center of the turntable 52111′ as it extends along the circumference of the turntable 52111′. A third sliding post 52112′ is disposed on the movement unit 40, and the number of arcuate slots 521111′ and third sliding posts 52112′ is the same as the number of movement units 40 provided. Exemplarily, the movement unit 40 may be a kinematic unit having the previously described structure. Specifically, the third sliding post 52112′ is disposed on a slide of the movement unit 40. Since the movement unit 40 is only capable of reciprocating, when the turntable 52111′ rotates around its central axis, it drives the third sliding post 52112′ to slide in its corresponding arcuate groove 521111′, which in turn drives the movement unit 40 corresponding to the third sliding post 52112′ to drive the cleaning head 30 thereon to reciprocate. In this embodiment, the number of movement units 40 is more than two groups, which can be set to two groups, three groups, four groups, six groups, eight groups, etc., as required, and it is only necessary to set the number of arcuate grooves 521111′ and the third sliding post 52112′ equal to the number of the movement units 40, and to spread the arcuate grooves 521111′ evenly on the turntable 52111′ along the center circumference of the turntable 52111′. It is possible to drive all the moving mechanisms 52120 through one set of rotating mechanisms 52110′, which in turn drives all of the movement units 40 and the cleaning heads 30 thereon to reciprocate between the first position and the second position. Exemplarily, four sets of movement units 40 are provided, referring to as first movement unit 41, second movement unit 42, third movement unit 43′ and fourth movement unit 44′, respectively for differentiation. The first movement unit 41 is provided to be capable of driving a cleaning head 30 disposed on the first movement unit 41 to reciprocate in a first direction X between a first position corresponding to when the cleaning head 30 is in an operating state and a second position corresponding to when the cleaning head 30 is in a non-operating state, driven by the drive unit 51. The second movement unit 42 is provided to be capable of driving the cleaning head 30 disposed on the second movement unit 42 to reciprocate in a second direction X′ between a first position corresponding to when the cleaning head 30 is in an operating state and a second position corresponding to when the cleaning head 30 is in a non-operating state, driven by the drive unit 51. The third movement unit 43′ is provided to be capable of driving the cleaning head 30 disposed on the third movement unit 43′ to reciprocate in a third direction Y between the first position corresponding to when the cleaning head 30 is in the operating state and the second position corresponding to when the cleaning head 30 is in the non-operating state, driven by the drive unit 51. The fourth movement unit 44′ is provided so as to be capable of driving the cleaning head 30 disposed on the fourth movement unit 44′ to reciprocate in the fourth direction Y′ between the first position corresponding to when the cleaning head 30 is in the operating state and the second position corresponding to when the cleaning head 30 is in the non-operating state, driven by the drive unit 51. The first direction X, the second direction X′, the third direction Y and the fourth direction Y′ are not in the same direction.
In some embodiments, as shown with continued reference to FIG. 16, the first movement unit 41 includes a first slider 411′ for being fixedly disposed relative to the corresponding cleaning head 30 and a first slideway fixedly disposed relative to the mounting base 20 and adapted to the first slider 411′. A second movement unit 42 includes a second slider 421′ for being fixedly disposed relative to a corresponding cleaning head 30 and a second slideway fixedly disposed relative to the mount 20 and adapted to the second slider 421′. The third movement unit 43′ comprises a third slider 431′ for being fixedly disposed relative to the corresponding cleaning head 30 and a third slideway fixedly disposed relative to the mounting base 20, adapted to the third slider 431′, with the fourth cleaning portion 34 in an operating state located on the third side 23 of the mounting base 20. The fourth moving unit comprises a fourth slider 441′ for being fixedly disposed relative to the corresponding cleaning portion and a fourth slideway fixedly disposed relative to the mounting base 20 and adapted to the fourth slider 441′. For example, the fifth cleaning portion 35 is disposed on the fourth slide 441′, and the fifth cleaning portion 35 is disposed in an operating state on the fourth side 24 of the mounting base 20.
In a preferred manner of this embodiment, as shown in FIGS. 15 and 16, the drive unit 51 is provided as a structure for driving the rotation mechanism a 52110′ to rotate about a first center axis perpendicular to the direction of motion of the movement unit 40, such as formed by the upper first rod 60 fixed to the rotation mechanism a 52110′. As a result, the space occupied by the rotation mechanism a 52110′ can be reduced. It is also possible to connect the first rod 60 to the turntable 52111′ of the rotation mechanism a 52110′ so as to rotate the turntable 52111′ by the first rod 60. Exemplarily, the first rod 60 is connected to the turntable 52111′ via a transfer block 71. For example, the turntable 52111′ is connected to the transfer block 71 by means of a snap connection to the first catch block 73, and the first rod 60 may be fixedly connected to the transfer block 71 or pivotably connected to the transfer block 71 around the second rotation axis 61. The second rotation axis 61 is provided parallel to the first direction X, the second direction X′, the third direction Y and the fourth direction Y.
Preferably, the embodiment may also include a locking module 53, which adopts the aforementioned snap-slot structure, which will not be repeated herein.
FIGS. 17 to 25 schematically show a cleaning tool according to at least one embodiment of the present invention. The cleaning tool includes the aforementioned synchronized multidirectional moving mechanism 100 for the cleaning tool (the specific structure of which is shown in FIGS. 1 to 16, and the position in which it is provided on the cleaning tool is shown in FIG. 19). By providing at least two groups of movement units 40, the present invention can avoid increasing the burden of cleaning work by carrying more than two kinds of cleaning appliances at the same time by providing cleaning heads 30 that can play different cleaning roles on the mount 20 of the cleaning tool by setting up the cleaning heads 30 on at least two groups of movement units 40 respectively. Each group of movement units 40 can separately drive the cleaning heads 30 disposed thereon to reciprocate between an operating state and an inoperative state, so that the cleaning heads 30, when in an inoperative state, can be driven by the corresponding movement units 40 to a position that is relatively compact in relation to the structure of the mounting base 20, in order to reduce the amount of space that the synchronized multidirectional movement mechanism 100 occupies for use with the cleaning tool and when in an inoperative state. Moreover, the operation of this synchronized multidirectional moving mechanism 100 is made more convenient because more than two sets of movement units 40 can be driven by a single drive module 50.
In some preferred embodiments, as shown in FIGS. 20 and 22, the cleaning tool further includes an transfer block 71 for connecting the first rod 60 pivotally disposed on the mounting base 20 by means of at least one set of pivotal connecting units 80 having locking structures 81 pivotally disposed on the first axis of rotation 801. The axial direction of the first axis of rotation 801 may be aligned with the lengthwise direction of the synchronous multidirectional moving mechanism 100 for the cleaning tool as previously described length direction, can be aligned with the width direction of the aforementioned synchronized multidirectional moving mechanism 100 for cleaning tools, and can be provided at an angle with respect to the length direction or the width direction of the aforementioned synchronized multidirectional moving mechanism 100 for cleaning tools. The locking structure 81 is provided to be capable of locking the transfer block 71 rotated with respect to the mounting base 20 at at least a first angle (as shown in FIG. 21) and at a second angle (as shown in FIG. 23) with respect to the mounting base 20. As a result, the transfer block 71 for connecting the first rod 60 is able to be locked relative to the mounting base 20 when the transfer block 71 is rotated at a first angle relative to the mounting base 20, and the transfer block 71 is also able to be locked relative to the mounting base 20 when the transfer block 71 is rotated at a second angle relative to the mounting base 20, so that the first rod 60 connected to the transfer block 71 is able to be stabilized at a different angle relative to the cleaning head 30 mounted on the mounting base 20. The cleaning head 30 is located at different angles with respect to the cleaning head 30 mounted on the mounting base 20, so that when the operator uses the cleaning head 30 on the mounting base 20 by grasping the first rod 60, the cleaning head 30 can be made to have at least two different cleaning orientations, satisfying the need for different cleaning orientations of the same cleaning tool and reducing the number of cleaning tools carried during cleaning work. Of course, it is also possible to realize that the transfer block 71 is locked with respect to the mounting base 20 when it is rotated to a set angle with respect to the mounting base 20 by setting the locking structure 81. This set angle can be adjusted according to the specific structure of the locking structure 81. As previously described, the number of set angles is at least two. The number of set angles may be more than two by adjusting the locking structure 81.
As one embodiment of the pivotal connecting unit 80, as shown in FIGS. 20 and 22, the pivotal connecting unit 80 includes at least one set of first pivot rods 82 disposed on one of the transfer block 71 and the mounting base 20, extending in the same direction as the direction Y in which the first axis of rotation 801 extends; and first pivot holes 83 disposed in the other of the transfer block 71 and the mounting base 20 adapted to fit the first pivot rods 82. For example, the first pivot rod 82 is integrally molded, machined, or attached to the transfer block 71, and the first pivot hole 83 is integrally molded or machined to the mounting base 20. Another example is that the first pivot rod 82 is integrally molded, machined, or attached to the mounting base 20 and the first pivot hole 83 is integrally molded or machined in the transfer block 71. As another example, the first pivot rod 82 is integrally molded, machined, or attached to the transfer block 71 and the mounting base 20, and the first pivot hole 83 is integrally molded or machined to the transfer block 71 and the mounting base 20. As a result, the transfer block 71 can pivot about the first pivot shaft 801 relative to the mounting base 20. The pivotal connecting unit 80 may also adopt other implementations in the prior art, as long as it is capable of realizing rotation of the transfer block 71 around the first rotation axis 801 relative to the mounting base 20. In a preferred embodiment, the first rotation axis 801 and the first pivoting rod 82 are integrated to simplify the structure of this adjustable mounting head. Preferably, as shown in FIG. 18, FIG. 20 and FIG. 22, the pivotal connecting unit 80 is provided in two groups and distributed on both sides of the transfer block 71 to ensure the stability of the rotation of the transfer block 71 relative to the mounting base 20.
As an embodiment of the locking structure 81, as shown in FIGS. 18, 20, and 22, the locking structure 81 includes a first snap-fitting portion 811 disposed on the transfer block 71, and a second snap-fitting portion 812 disposed on the mounting base 20 and adapted to fit the first snap-fitting portion 811. The first snap-fitting portion 811 and the second snap-fitting portion 812 are provided to be able to snap together snap-fitting portion to increase the resistance to the rotation of the transfer block 71 around the first axis of rotation axis 801 with respect to the mounting base 20 at least when the transfer block 71 rotates around the first rotation axis 801 at a first angle and a second angle. As a result, relative locking of the transfer block 71 with the mounting base 20 can be realized by means of the first snap-fitting portion 811 catching the second snap-fitting portion 812.
In some embodiments, one of the first snap-fitting portion 811 and the second snap-fitting portion 812 includes at least two sets of the first raised portions 8111 and at least two sets of the first recessed portions 8112. All of the first raised portions 8111 and the first recessed portions 8112 are disposed circumferentially around the center of the first axis of rotation 801 (an angle at which the first raised portions 8111 and the first recessed portions 8112 are disposed circumferentially may be set according to needs, and may be evenly or unevenly distributed), and the first raised portions 8111 and the first recessed portions 8112 are disposed adjacent to each other. That is, there are at least two sets of the first projection portions 8111, and the number of the first recessed portions 8112 is the same as the number of the first projection portions 8111. The other of the first snap-fitting portion 811 and the second snap-fitting portion 812 includes at least one set of second projection portions 8121 adapted to fit into the first recessed portion 8112 so that the second projection portions 8121 can snap onto the first recessed portion 8112 when the transfer block 71 is rotated to a first angle with respect to the mount base 20. When the transfer block 71 is rotated to a second angle with respect to the mount base 20, the second projections 8121 and snap into the first recessed portion 8112. Of course, the second snap-fitting portion 812 may also include a second recessed portion 8122 that separates adjacent second projection portions 8121. As a result, when the transfer block 71 is rotated such that the second projection portions 8121 snap into the first recessed portion 8112, the resistance to rotation of the transfer block 71 with respect to the mounting base 20 increases, allowing the transfer block 71 to be locked with respect to the mounting base 20. mounting base Since the first snap-fitting portion 811 and the second snap-fitting portion 812 that snap together only increase the resistance to rotation of the transfer block 71 with respect to the mounting base 20, when it is necessary to rotate the transfer block 71 with respect to the mounting base 20, it is only necessary to overcome the resistance generated by the snap together of the first snap-fitting portion 811 and the second snap-fitting portion 812 to rotate the transfer block 71 with respect to the mounting base 20 so as to adjust the angle of rotation of the transfer block 71 with respect to the mounting base 20. transfer blockmounting base Moreover, when the transfer block 71 is rotated around the first rotation axis 801 to a first angle and a second angle with respect to the mounting base 20, the first snap-fitting portion 811 and the second snap-fitting portion 812 can be snapfi-fit, realizing automatic locking of the transfer block 71 with the mounting base 20 without the use of external tools, rendering the operation convenient. When the second snap-fitting portion 812 includes a plurality of second projection portions 8121, all the first recessed portions 8112 are evenly distributed around the circumference with the first rotation axis 801 as the center. The number of the second projection portions 8121 is not greater than the number of the first recessed portions 8112, and the angle of the two sets of second projection portions 8121 is the same as the angle of the two sets of first recessed portions 8112. As a result, the angle at which the transfer block 71 is rotated when locked with respect to the mounting base 20 can be controlled by controlling the number of the first projection portions 8111. For example, when the number of the first projection portion 8111 is 2, the angle of rotation is 180°. When the number of the first projection portions 8111 is 3, the angle of rotation is 120°. When the number of the first projections 8111 is 4, the angle of rotation is 90°. When the number of the first projection portions 8111 is 5, the angle of rotation is 72°. When the number of the first projection portions 8111 is 6, the angle of rotation is 60°. When the number of the first projections 8111 is 8, the angle of rotation is 45°. That is, the angle of rotation A=360/n, n being the number of the first projection portions 8111. As a result, when the transfer block 71 is rotated until the second projection portion 8121 snaps into the first recessed portion 8112, the resistance to rotation of the transfer block 71 with respect to the mounting base 20 increases, enabling the transfer block 71 to be locked with respect to the mounting base 20. When the first projection portion 8111 is provided in a plurality of sets, the first snap-fitting portion 811 is, for example, a first end face gear structure or a first end face ratchet structure, and the second snap-fitting portion 812 is a second end face gear structure or a second end face ratchet structure adapted to the first snap-fitting portion 811. As a result, the angle of rotation of the transfer block 71 when locked with respect to the mounting base 20 can be controlled by controlling the number of teeth of the gear or ratchet. The angle of rotation A=360/Z, and Z is the number of teeth. As an embodiment in which the second projection 8121 can snap into the first recessed portion 8112, at least one of the first projection 8111 and the second projection 8121 is made of a material having an elastic deformation capability, such as plastic. In a preferred embodiment of this embodiment, the pivoting connection unit 80 further comprises at least one set of first pivot rods 82 disposed on either of the transfer block 71 and the mounting base 20, extending in the same direction as that of the first axis of rotation 801, and first pivot holes 83 disposed on the other side of the transfer block 71 and the mounting base 20 adapted for use with the first pivot rods 82, thereby realizing a pivoting of the transfer block 71 relative to the mounting base 20. transfer blockmounting base. Preferably, the cleaning tool further comprises a first elastic member 84. A second snap-fitting portion 812 is movably disposed on the mounting base 20 in the extension direction of the first rotation axis 801. The first elastic member 84 is provided so that its elasticity can drive the second snap-fitting portion 812 towards the side on which its corresponding first snap-fitting portion 811 is located. As a result, the second snap-fitting portion 812 can be held against the first snap-fitting portion 811 with the elastic force of the first resilient member 84 to ensure the stability of the second snap-fitting portion 812 snap-fitting onto the first snap-fitting portion 811. As an embodiment of the second snap-fit portion 812 being movable in the extension direction of the first rotation axis 801 being disposed on the mounting base 20, as shown in FIG. 18, the second snap-fit portion 812 is movable in the extension direction of the first rotation axis 801 being disposed on the mounting base 20 by means of a first moving structure. Exemplarily, the first moving structure includes a second sliding channel 20111 and a sliding member. The second sliding channel 20111 extends in the extension direction of the first rotation axis 801. The sliding member is adapted to the second sliding channel 20111 to be able to reciprocate in the second sliding channel 20111 along the extending direction of the first axis of rotation 801. The second sliding channel 20111 is integrally molded or machined on the mounting base 20, and the sliding member is integrally molded or attached to the second snap-fitting portion 812 to enable the second snap-fitting portion 812 to reciprocally move in the direction of extension of the second sliding channel 20111. That is, the second snap-fitting portion 812 is molded or coupled to enable reciprocal movement in the direction of extension of the first axis of rotation 801. Exemplarily, the first elastic member 84 may be a resilient sheet or spring. The first pivot hole 83 is preferably disposed on the mounting base 20 via the second snap-fitting portion 812. As a result, machining of the first pivot hole 83 may be facilitated. Moreover, since the first pivot rod 82 disposed on the transfer block 71 is adapted to fit in the first pivot hole 83 on the second snap-fitting portion 812, the accuracy of the assembly position of the first snap-fitting portion 811 on the transfer block 71 and the second snap-fitting portion 812 can be ensured. Further, to ensure the stability of the first elastic member 84 against the second snap-fitting portion 812, as shown in FIG. 3, the first elastic member 84 is a first compression spring socketed on the first pivot rod 82. Thereby, the stability of the first elastic member 84 against the second snap-fitting portion 812 can be improved. Preferably, the mounting base 20 includes a removably connected top plate 2011 and a bottom plate 2012, and the second sliding channel 20111 is integrally molded or machined on the top plate 2011. The top plate 2011 is integrally molded or machined with an opening for the pivotal connecting unit 80 to be mounted into the second sliding channel 20111. The opening is located on the side of the top plate 2011 facing the bottom plate 2012 for mounting the pivotal connecting unit 80 into the second sliding channel 20111 when the top plate 2011 is detached from the bottom plate 2012.
As other embodiments, as shown in FIG. 10, one of the first snap-fitting portion a 811′ and the second snap-fitting portion 812 includes at least two sets of first recessed portions a 8112′. All of the first recessed portions a 8112′ are distributed circumferentially centered on the first rotation axis 801. The angle at which the first snap-fitting portion a 811′ locks after rotation relative to the second snap-fitting portion 812 may be defined by the angle at which adjacent first recessed portions a 8112′ are pinched. For example, when the angle of the adjacent first recessed portions a 8112′ is 180°, interlocking of the first snap-fitting portions 811′ with respect to the second snap-fitting portion 812 after rotation of the first snap-fitting portion a 811′ by 180° can be realized. For example, when adjacent first recessed portions a 8112′ have an angle of 90°, the first snap-fitting portions 811′ can be locked to each other after a rotation of 90° with respect to the second snap-fitting portion ee812 (as shown in FIG. 19, FIG. 21 and FIG. 23). The number of first recessed portions a 8112′ may be two (as shown in FIG. 25), three (as shown in FIG. 24) or four. The other of the first snap-fitting portion a 811′ and the second snap-fitting portion 812 includes at least one set of second projections 8121 adapted to fit into the first recessed portion 8112′. Exemplarily, the first recessed portion may be a “V”-shaped first recessed portion 8112 (as shown in FIGS. 6 and 7), a “U”-shaped first recessed portion 8112 (as shown in FIGS. 19 and 23), or an “U”-shaped first recessed portion 8112′ (as shown in FIG. 24), or a planar first recessed portion 8112 (as shown in FIG. 25). When the first recessed portion is a planar first recessed portion 8112″, adjacent first recessed portions a 8112″ are separated from each other by a first projection portion 8111″. The first projection portion 8111″ may be a linear type of projection or a curved type of projection. As a result, when the transfer block 71 is rotated until the second projection portion 8121 snaps into the first recessed portion 8112′, the resistance to rotation of the transfer block 71 with respect to the mounting base 20 increases, allowing the transfer block 71 to be locked with respect to the mounting base 20. In a preferred embodiment, the pivotal connecting unit 80 further includes at least one set of first pivot rods 82 disposed on either of the transfer block 71 and the mounting base 20, extending in the same direction as the extension of the first rotation shaft 801, and a first elastic member 84′. The second projection portion 8121 is reciprocally movable in a direction perpendicular to the axis of the first rotation shaft 801 against the periphery of the first rotation axis 801 under the elastic force of the first elastic member 84′. Specifically, one end of the first elastic member 84′ rests against the mounting base 20 and the other end rests against the second projection portion 8121. As a result, when the first snap-fitting portion 811 is rotated about the axis of the first rotation axis 801 until the first recessed portion 8112 thereon is aligned with the second projection portion 8121, the second projection portion 8121 can be snapped into the first recessed portion 8112 under the elastic force of the first elastic portion 84. When the clastic force of the first elastic portion 84′ is overcome, it is possible to continue to allow the first snap-fitting portion 811 to be rotated about the first rotation shaft 801.
In yet other embodiments, the first snap-fitting portion 811 and the second snap-fitting portion 812 may also be provided such that when the second snap-fitting portion 812 rests against the first snap-fitting portion 811 under the action of the first clastic portion 84, it rotates the first rod 60 around the first rotation shaft 801. Referring to FIGS. 26 to 28, exemplarily, the first snap-fitting portion 811 is provided with a first annular surface 231 including a plurality of sequentially disposed first bumps 232 and first concave points 233. A first continuous beveled surface 234 is provided between the first bumps 232 and the first concave points 233. A second annular surface 235 is provided on the second snap-fitting portion 812 including a plurality of sequentially disposed second bumps 236 and A second continuous beveled surface 238 is provided between the second bumps 236 and the second concave points 237. Two first bumps 232 and two first concave points 233 are provided spaced apart on the first annular surface 231. The first bumps 232 are spaced apart at an angle of 90 degrees from the first concave points 233 such that the two first bumps 232 and the two first concave points 233 are distributed at each of the four corners of the first annular surface 231. Similarly, two second bumps 236 are provided with two second concave points 237 spaced apart on the second annular surface 235. The second bumps 236 and the second concave points 237 are spaced apart at an angle of 90 degrees so that the two second bumps 236 and the two second concave points 237 are distributed at the four corners of the second annular surface 235. The surfaces of the above-described first bumps 232, second bumps 236, first concave points 233, and second concave points 237 all have a certain curvature. At this time, when the first elastic member 84 drives the second bump 236 of the second snap-fitting portion 812 against the first bump 232 on the first snap-fitting portion 811, the second bump 232 slides into the first concave point 233 along the first continuous beveled surface 234 and causes the transfer block 71 to rotate around the first rotation shaft 801.
Specifically, in this embodiment, when the first rod 60 is opened and perpendicular to the mounting base 20, i.e., as shown in FIG. 27, the first bump 232 and the second bump 236 are provided opposite each other. At this time, when the first elastic member 84 pushes the second snap-fitting portion 812, since the above-described first bump 232, second bump 236, first concave point 233, and second concave point 237 all have a certain curvature, it will cause the first bump 232 and the second bump 236 to be unstably pressed against each other, thereby causing the first bump 232 to slide into the second concave point 237 along the second continuous sloping surface 238 until it is in a state as shown in FIG. 28. At this point the transfer block 71 is rotated 90 degrees about the first rotation shaft 801 to be parallel to the mounting base 20. The presence of the first elastic member 84 constantly driving the first bump 232 against the second bump 236 will cause the transfer block 3 to always tend to rotate around the first rotation shaft 801. With this tendency, the mounting block 20 can always be turned inwardly and not outwardly when the user operates the cleaning tool for use, preventing the mounting block 20 from being turned outwardly to interfere with normal operation, and increasing the user's sense of product experience. It is particularly noted that the first annular surface 231 and the second annular surface 235 in this embodiment cooperate not to allow the cleaning tool to lock at a set angle, but to allow the cleaning tool to have a tendency to reset its movement towards a set attitude.
In some preferred embodiments, the cleaning tool further includes a cleaning head 30 disposed on the movement unit 40. The mounting base 20 is provided with a holding space 2001 having the ability to hold the cleaning head 30 and at least two entrances and exits 2002 for the cleaning head 30 to enter and exit the holding space 2001. When the cleaning head 30 is in a first position, at least a portion of the cleaning head 30 protrudes from the entrances and exits 2002 to an exterior of the holding space 2001. When the cleaning head 30 is in the second position, the cleaning head 30 is located inside the holding space 2001. The at least two outlets are provided on surfaces of different sides of the mounting base 20. It is thus possible to provide the cleaning heads 30, which play different cleaning roles, separately on at least two sets of movement units 40, to avoid increasing the burden of cleaning work caused by carrying more than two types of cleaning appliances at the same time. When the cleaning portions are not required to be used, the cleaning heads 30 can be stowed in the first holding cavity 201 of the mounting base 20 by adjusting their corresponding cleaning heads 30 to a second position by the movement units 40 to ensure a compactness of the structure of the cleaning tool. Exemplarily, two sets of cleaning heads 30, namely a first cleaning portion 31 and a second cleaning portion 32 are provided. The first cleaning portion 31 is disposed on the first movement unit 41, and the second cleaning portion 32 on the second movement unit 42. The mounting base 20 is provided with a first holding chamber 201 having a first opening 202, and/or with a second holding chamber 203 having a second opening 204. The first holding chamber 201 and the second holding chamber 203 are the aforementioned holding spaces 2001, and the first opening 202 and the second opening 204 are the aforementioned entrances and exits 2002. When the first cleaning portion 31 and the second cleaning portion 32 are in the first position, at least a portion of the first cleaning portion 31 protrudes from the first opening 202 to the exterior of the first holding cavity 201 and at least a portion of the second cleaning portion 32 protrudes from the second opening 204 to the exterior of the second holding chamber 203. When the first cleaning portion 31 and the second cleaning portion 32 are in the second position, the first cleaning portion 31 is disposed in an interior of the first holding chamber 201 and the second cleaning portion 32 is disposed in an interior of the second holding chamber 203. The first opening 202 and the second opening 204 are provided on surfaces on different sides of the mounting base 20.
In some preferred embodiments, as shown in FIGS. 8, 9, and 17 through 23, the cleaning tool further includes a first rod 60 disposed on the transfer block 71, and disposed on the fifth side 25 of the mounting base 20. As shown in FIG. 10, FIG. 18, and FIG. 20, to facilitate the attachment of the transfer block 71 to the first rod 60, the mounting base 20 is preferably also integrally molded or machined with a first connecting portion 20112 that connects the second sliding channel 20111 to the exterior. A locking structure 81 is disposed in the second sliding channel 20111, and a portion of the transfer block 71 for attachment to the first rod 60 is disposed in the first connecting portion 20112 on the exterior of the first connecting port. Preferably, the first rod 60 is pivotably disposed on the transfer block 71 around the second rotation shaft 61 and is not parallel to the first rotation shaft 801, as shown in FIGS. 18 to 23. FIGS. 17 to 18 exemplarily show a schematic diagram of a first state of the first rod 60 pivoting around the second rotation shaft 61 with respect to the transfer block 71, i.e., the first rod 60 is in a first position with respect to the mounting base 20. FIG. 19 exemplarily shows a schematic diagram of a second state of rotation of the first rod 60 about the second rotation shaft 61 with respect to the transfer block 71, i.e., the first rod 60 is in a second position with respect to the mounting base 20. FIG. 21 exemplarily shows a schematic diagram of a third state when the transfer block 71 is rotated to a first angle with respect to the mounting base 20 and the first rod 60 is rotated around the second rotation shaft 61 with respect to the transfer block 71 in the second state, i.e., the first rod 60 is in the third position with respect to the mounting base 20. FIG. 23 exemplarily shows a schematic diagram of a fourth state in which the first rod 60 is in a fourth position with respect to the mounting base 20 due to the transfer block 71 being rotated to a second angle with respect to the mounting base 20 and the first rod 60 being rotated about the second rotation shaft 61 with respect to the transfer block 71. As a result, the ways in which the first rod 60 can be rotated relative to the mounting base 20 can be further increased to allow for a more varied cleaning orientation of the hand-held first rod 60 using the cleaning portion mounted on the mounting base 20. Preferably, the first rotation shaft 801 and the second rotation shaft 61 are provided perpendicular to each other.
Further, to enable the first rod 60 to be locked with respect to the mounting base 20 when it is rotated to a set angle with respect to the mounting base 20, the cleaning tool also includes a locking unit capable of locking the first rod 60 and the mounting base 20 with each other when the angle with the mounting base 20 is the set angle. As an embodiment, the locking unit includes a fifth locking mechanism 62 capable of locking the first rod 60 at a first angle of rotation relative to the mounting base 20 mounting base; and/or a sixth locking mechanism 63 capable of locking the first rod 60 at a second angle of rotation relative to the mounting base 20 to the mounting base 20. As an embodiment, the fifth locking mechanism 62 includes a fifth snap 621 and a fifth slot 622 capable of being snap-fit coupled to each other. At least one of the fifth snap 621 and the fifth slot 622 is disposed on the first rod 60 and the other is disposed on the mounting base 20. For example, the fifth snap 621 is disposed on the first rod 60, and the fifth snap 621 and the fifth slot 622 are provided to be able to snap into each other when the first rod 60 is rotated to a first angle with respect to the mounting base 20 (as shown in FIG. 9). As an embodiment, the sixth locking mechanism 63 includes a sixth snap 631 and a sixth slot 632 that are adapted to each other. At least one of the sixth snap 631 and the sixth slot 632 is disposed on the first rod 60 and the other is disposed on the mounting base 20. For example, the sixth snap 631 is disposed on the first rod 60 and and the sixth slot 632 are provided to be able to snap into each other when the first rod 60 is rotated to a second angle relative to the mounting base 20. As an alternative embodiment, the fifth locking mechanism 62 includes a third screw hole and a third screw that are adapted to each other. At least one of the third screw hole and the third screw is disposed on the first rod 60 and the other is disposed on the mounting base 20. For example, the third screw is pivotably disposed on the first rod 60. The third screw hole and the third screw are provided such that the third screw can be adapted to fit in the third screw hole when the first rod 60 is rotated to a first angle with respect to the mounting base 20. As another embodiment, the sixth locking mechanism 63 includes a fourth screw hole and a fourth screw adapted to each other, with at least one of the fourth screw hole and the fourth screw disposed on the first rod 60 and the other disposed on the mounting base 20. For example, the fourth screw is pivotably disposed on the first rod 60, and the fourth screw hole and the fourth screw are provided such that the fourth screw can be adapted to fit in the fourth screw hole when the first rod 60 is rotated to a second angle with respect to the mounting base 20.
In some embodiments, as shown in FIG. 30, a joint 72 may be provided at one end of the first rod 60 toward the mounting base 20. A adapter seat 2016 may be provided on the mounting base 20 along the axial direction of the first rotation shaft 801, and is connected to the joint 72 through an transfer block 71 by which the first rod 60 is caused to rotate around the first rotation shaft 801 and/or rotate around the second rotation shaft 61. A locking slot 641 may also be provided on one side of the joint 72, which in turn allows the locking slot 641 to be snapped in place outside the adapter seat 2016 when the first rod 60 is rotated around the second rotation shaft 61 and against the mounting base 20, thereby restricting the rotation of the first rod 60 around the second rotation shaft 61. Specifically, the adapter seat 2016 may include a first seat body 20161 and a second seat body 20162, and a second sliding channel 20111 is provided in the first seat body 20161 and the second seat body 20162. The first connecting port 20112 is provided on one side of the first seat body 20161 and the second seat body 20162 toward the middle of the adapter seat 2016, respectively. The locking slot 641 is oriented in the direction of the axis of the first rotation shaft 801 on the mounting base 20 toward the first seat body 20161 or the second seat body 20162 depending on whether the locking slot 641 is provided on the left or the right side of the joint 72. When the first rod 60 is rotated around the second rotation shaft 61 and against the mounting base 20, the locking slot 641 is snapped into place outside the adapter seat 2016. When the first rod 60 is rotated around the second rotation shaft 61 so that the first rod 60 is against the mounting base 20, the locking slot 641 snaps into place outside the adapter seat 2016 because the locking slot 641 is opposite and adapted to the first seat body 20161 or the second seat body 20162 on one side of the adapter seat 2016. That is, as shown in FIG. 28, at this time, the first rod 60 can be positioned in a folded state by restricting the rotation of the first rod 60 around the second rotation shaft 61 by snapping the locking slot 641 to the first seat body 20161 or the second seat body 20162.
Further, an outer edge of the transfer block 71 may be provided with a curved sliding surface 711. The curved sliding surface 711 is provided with a few positioning slots 712. A push block 642 is provided within the other side of the joint 72, the inner end of which is provided with a second elastic portion 643 that drives the push block 642 outwardly. The other end of the push block 642 rests against the sliding surface 711 of the transfer block 71 for restricting the rotation of the first rod 60 about the first rotation shaft 801 when the first rod 60 rotates so that the push block 642 rests against the positioning slots 712.
As shown in FIGS. 28 and 30, a partition 644 is formed in the connector 72 by means of a spacer, and the partition 644 is provided with a push block 642 and a second elastic member 643. the transfer block 71 has a sliding surface 711 disposed along the axial direction of the first rotational shaft 801. In this embodiment, the positioning groove includes at least a first positioning slot 7121 and a second positioning slot 7122. As shown in FIGS. 29 and 30, the positioning slots 712 correspond to the working state and the folded state of the flat mop. When the push block 642 rests against the first positioning slot 7121, the first rod 60 is vertically positioned on the mounting base 20. When the push block 642 rests against the second positioning slot 7122, the first rod 60 is flat on the mounting base 20 and the locking slot 641 is snapped outside the adapter seat 2016. An end of the push block 642 is provided with a top head 6421 having a rounded surface. The first positioning slot 7121 and the second positioning slot 7122 are both circularly curved slots. When the first rod 60 is rotated, the top head 6421 on the push block 642 slides along the sliding surface 711. When the top head 6421 slides into the first positioning slot 7121 or the second positioning slot 7122, the second elastic portion 643 pushes the top head 6421 of the push block 642 into the first positioning slot 7121 or the second positioning slot 7122 to achieve positioning. A user may push the mounting base 20 to cause the push block 642 to overcome the second elastic portion 643 to disengage from the first positioning slot 7121 or the second positioning slot 7122, thereby making the first rod 60 rotate.
Referring to FIG. 29, when the first rod 60 rotates around the second rotation shaft 61 against the mounting base 20, the locking slot 641 is snapped onto the first seat body 20161 of the adapter seat 2016, and the push block 642 is pressed against the second positioning slot 7122. At this time, the positioning slot 712 and the locking slot 641 can be used to restrict the rotation of the first rod 60 around the second rotation shaft 61 and the rotation of the first rotation shaft 801, respectively, thereby realizing complete positioning of the mounting base 20.
In some embodiments, as shown in FIGS. 31 to 35, the cleaning tool further includes a water removal structure 200. The water removing structure includes a second rod 11, a mop head 17, and a water removing section 15. The second rod 11 is connected to the first rod 60 and is provided to reciprocate relative to each other along the fifth direction Z. The second rod 11 is provided with a third elastic portion 16 that is connected to the first rod 60. A third elastic member 16 is provided between the first rod 60 and the second rod 11, and is combined with the first rod 60 and the second rod 11 to form the mop bar 10. The first rod 60, the second rod 11, the third elastic member 16, the mounting base 20, the mop head 17, and the water removing portion 15 are provided such that, when the first rod 60 drives the mounting base 20 and the mop head 17 to move in the fifth direction Z with respect to the second rod 11, the water removing portion 15 can scrape the mop in the fifth direction Z. The water removing section 15 can scrape water from the mop head 17, and the third elastic member 16 can drive the first rod 60 to move away from the fifth direction Z relative to the second rod 11 to separate the mop head 17 from the water removing section 15. Exemplarily, the water removal section 15 is a block or plate for scraping water from the mop head 17. Exemplarily, the third elastic member 16 is a compression spring. As a result, the compression spring is pressurized to elastically deform when the first rod 60 is moved relative to the second rod 11 in the fifth direction. When the external force that moves the first rod 60 along the fifth direction is removed, the first rod 60 may return to its original position under the elastic force of the compression spring. Generally, when the mop head 17 is separated from the water removal section 15, the mop head 17 is disposed on the side of the water removal section 15 that is back from the second rod 11 to facilitate cleaning by the mop head 17.
As a result, when water is to be removed from the mop head 17, the end of the mounting base 20 backing away from the second rod 11 can be pressed against the stationary table. Then, by moving the first rod 21 in the fifth direction Z relative to the second rod 11, the water removing portion 15 is brought into contact with the mop head 17, so that the water removing portion 15 scrapes off the water from the mop head 17 in the process of moving relative to the mop head 17. The operation process requires only a one-handed grip of the second rod 11, which provides convenienience. Moreover, when an external force that moves the first rod 60 relative to the second rod 11 is removed, the first rod 60 can be restored to its original position by the elastic force of the third elastic portion 16 so that the mop head 17 with the removed water can be used.
In some preferred embodiments, as shown in FIG. 31, FIG. 32, FIG. 34, and FIG. 35, the mop that facilitates water removal further includes a first locking assembly 18 capable of locking the first rod 60 to the second rod 11 when the mop head 17 is separated from the water removal portion 15. When the mop head 17 is separated from the water removal portion 15, the mop head 17 can be cleaned through the mop head 17. By locking the first rod 60 with the second rod 11 by the first locking assembly 18, the stability of the structure of the mop bar 10 can be ensured when the mop head 17 is cleaned.
As an embodiment of the first locking mechanism 531, as shown in FIG. 35, the first locking assembly 18 includes a first through-hole 121 integrally molded or machined in the first rod 60, a second through-hole 122 integrally molded or machined in the second rod 11, and a locking block 182 pivotally disposed on one of the first rod 60 and the second rod 11 about the third pivot shaft 181.

This allows for a more compact structure of the formed mop bar 10. Preferably, the third elastic member 16 is accommodated in the first accommodation space 13 and has one end against the bottom of the cavity of the first accommodation space 13 and the other end against the first rod 60. Thereby, on the one hand, the compactness of the overall structure of the mop can be ensured, and on the other hand, the influence of external structures other than the first rod 60 and the second rod 11 on the third elastic member 16 can be avoided, to ensure the stability of the operation of the third elastic member 16. In this embodiment, the locking block 182 is pivotably disposed on the second rod 11 around the third pivot shaft 181.
A preferred embodiment of the water removal section 15 is shown in FIGS. 31, 33 and 35.
