In one embodiment of the present application, the base station 30 includes a base station body 31, a dirt pumping assembly 33 and a water injection assembly 35. The dirt pumping assembly 33 is provided in the base station body 31 and movable relative to the base station body 31 to communicate with the host dirt collecting chamber 111. The water injection assembly 35 is provided in the base station body 31 and movable relative to the base station body 31 to communicate with the host clean water chamber 112.
In an embodiment of the present application, the cleaning robot 10 can include a robot body 11. The robot body 11 can be configured for mounting and carrying various components of the cleaning robot 10 (e.g., a cleaning brush 13, a moving wheel 15, a motor for driving the moving wheel 15 to rotate, and a host fan for communicating with the host dirt collecting chamber 111 to generate suction at a dirt collecting port of the host dirt collecting chamber 111 to absorb garbage and sewage on the ground, etc.), so that various components of the cleaning robot 10 can be assembled into a whole. The projection of the robot body 11 on a horizontal plane can be approximately circular, so that side circumferential surfaces of the robot body 11 are consistent, and the robot body 11 can move more smoothly when turning at a corner or an obstacle. In addition, this arrangement makes the shape of the robot body 11 more regular and facilitates molding and manufacturing. Of course, the present application is not limited to this and in other embodiments, the projection of the robot body 11 on the horizontal plane can be square or rectangular or the like.
The host dirt collecting chamber 111 formed in the robot body 11 can be used for collecting garbage and sewage absorbed by the cleaning robot 10 when cleaning the ground. Specifically, the host fan in the robot body 11 is communicated with the host dirt collecting chamber 111. The host fan pumps air from the host dirt collecting chamber 111, so that negative pressure is formed in the host dirt collecting chamber 111, and garbage and sewage on the ground are sucked into the host dirt collecting chamber 111 for storage and collection. Since the cleaning robot 10 carrying out adsorption and collection of garbage and sewage on the ground through pumping air from the dirt collecting chamber by the host fan to form a negative pressure is already exist in prior art, it will not be described in detail here. The host dirt collecting chamber 111 can be formed directly in the host, or a host dirt collecting box is additionally embedded in the host, and the host dirt collecting chamber 111 is formed in the host dirt collecting box. The present application does not limit the specific formation and shape of the host dirt collecting chamber 111, as long as it can store and collect garbage and sewage absorbed by the cleaning robot 10 during working.
The host clean water chamber 112 can be configured for storing a certain amount of clean water so that the cleaning robot 10 can spraying water and clean the ground during the cleaning of the ground, thereby improving the cleaning effect of the cleaning robot 10 to clean the ground. The host clean water chamber 112 can be formed directly on the host, or a host clean water tank is additionally embedded in the host, and the host clean water chamber 112 is formed in the host clean water tank. The present application is not limited to the specific formation and shape of the host clean water chamber 112, as long as it can store a certain amount of clean water for the cleaning robot 10 to wash the ground when working. The water spraying of the cleaning robot 10 can be realized by providing a host nozzle 11g on the robot body 11, and the host nozzle 11g is communicated with the body clean water chamber 112 and can spray water toward the ground or the cleaning brush 13 of the cleaning robot 10.
The base station body 31 of the base station 30 can be configured for mounting and carrying various components of the base station 30 (e.g., the dirt pumping assembly 33, the water injection assembly 35, and a controller of the base station 30, etc.), so that the various components of the base station 30 can be assembled into a whole. The base station body 31 can be substantially rectangular, so that the base station body 31 has a regular shape and facilitates molding and manufacturing. Further, a length direction of the base station body 31 can be parallel to the up-down direction, so that the projection of the base station body 31 on the horizontal plane is relatively small, and the occupation of the ground by the base station 31 can be reduced. Of course, the present application is not limited to this and in other embodiments, the base station body 31 can be substantially square or cylindrical.
In an embodiment, referring to
In order to improve the cleaning effect of cleaning the ground, in an embodiment of the present application, the base station body 31 can also be provided with a liquid detergent chamber, and the water injection assembly 35 is communicated with the liquid detergent chamber. At this time, the liquid detergent is stored in the liquid detergent chamber, when the cleaning robot 10 is moved to the base station 30 for docking, the liquid detergent in the liquid detergent chamber is fed into the host clean water chamber 31b by the water injection assembly 35, at the time that the water injection assembly 35 injects water to the host clean water chamber 31b. Thus, when the cleaning robot 10 cleans the floor afterwards, cleaning water with liquid detergent can be sprayed through the host nozzle 11g, thereby achieving better cleaning of the ground. The liquid detergent chamber can be formed directly in the base station body 31, or the base station body 31 can be additionally provided with a liquid detergent storage box in which the liquid detergent chamber is formed. Of course, it needs to be explained that, the present application is not limited to this.
In other embodiments, when the base station body 31 is not formed with the base station dirt collecting chamber 31a and the base station clean water chamber 31b, the dirt pumping assembly 33 can include a collection box, and the water injection assembly 35 can include a water storage tank, garbage and sewage pumped by the dirt pumping assembly 33 are collected by the collection box and clean water are stored by the water storage tank. The dirt pumping assembly 33 can be configured to generate suction and pump garbage and sewage from the host dirt collecting chamber 111. The dirt pumping assembly 33 can include a dirt pumping fan, i.e., the dirt pumping fan pumps air from the host dirt collecting chamber 111 through the dirt pumping fan. In addition, when the dirt pumping assembly 33 pumps dirt from the host dirt collecting chamber 111, the host fan in communication with the host dirt collecting chamber 111 of the host needs to be turned off, so that only the air flow from the host dirt collecting chamber 111 to the dirt pumping fan is formed.
The water injection assembly 35 can be used to inject water into the host clean water chamber 112 to replenish water. When the base station clean water chamber 31b is provided at a relatively high position or the water storage tank of the water injection module 35 is relatively high, the water injection module 35 can supply clean water to the host clean water chamber 112 by gravity. When the position of the base station clean water chamber 31b or the position of the water storage tank of the water injection assembly 35 is relatively low, the water injection assembly 35 can include a water pump, that is, the water pump provides power to pump the clean water in the base station clean water chamber 31b or in the water storage tank of the water injection assembly 35 into the host clean water chamber 112.
When the base station 30 according to the technical solution of the present application is in use, the dirt pumping assembly 33 and the water injection assembly 35 are driven close to the cleaning robot 10, so that the dirt pumping assembly 33 communicates with the host dirt collecting chamber 111 of the cleaning robot 10, and the water injection assembly 35 communicates with the host clean water chamber 112 of the cleaning robot 10. At this time, the dirt pumping assembly 33 can pump air from the host dirt collecting chamber 111 on the cleaning robot 10, thereby realizing the pumping of garbage and sewage from the host dirt collecting chamber 111. The water injection assembly 35 can inject water into the clean water chamber of the cleaning robot 10, thereby replenishing clean water to the host clean water chamber 112.
Therefore, in the present technical solution, after the base station 30 is docked with the cleaning robot 10, the garbage stored in the cleaning robot 10 can be pumped away, and the host clean water chamber 112 can be replenished with clean water. In this way, compared with the prior art in which the base station 30 can only collect the garbage stored in the cleaning robot 10, causing that the user needs to manually replenish water to the host water chamber 112 of the cleaning robot 10 after use, the base station 30 according to the technical solution has a variety of functions and does not require the user to manually replenish water to the host clean water chamber 112 of the cleaning robot 10, thereby improving the practicability of the base station 30.
Further, the dirt pumping assembly 33 and the water injection assembly 35 of the technical solution are movably arranged on the base station body 31, so that the dirt pumping assembly 33 and the water injection assembly 35 can have a certain distance from the cleaning robot 10 before the cleaning robot 10 is moved in place during the docking process with the base station 30. Only after the cleaning robot 10 is moved in place, the dirt pumping assembly 33 and the water injection assembly 35 are moved close to the cleaning robot 10 to pump dirt (pump away the garbage stored in the cleaning robot 10) and inject water (replenish clean water to the host clean water chamber 112). Thus, the cleaning robot 10 is prevented from colliding with the dirt pumping assembly 33 and the water injection assembly 35 of the base station 30 during the docking process of moving close to the base station 30, thereby reducing the possibility of damage to the cleaning robot 10, the dirt pumping assembly 33 and the water injection assembly 35 due to the collision.
Referring to
Understandably, the dirt pumping assembly 33 and the water injection assembly 35 are provided on the base station body 31 in such a way that they can be lifted and lowered relative to the base station body 31 (it may be that only one end of the dirt pumping assembly 33 and the water injection assembly 35 for docking with the cleaning robot 10 can be lifted and lowered, of course, it may be the whole of the dirt pumping assembly 33 and the whole of the water injection assembly 35 that can be lifted and lowered with respect to the base station body 31, and flexible pipes can be connected to the dirt pumping assembly 33 and the water injection assembly 35 opposite to the ends of the dirt pumping assembly 33 and the water injection assembly 35 docking with the cleaning robot 10), so that the dirt pumping assembly 33 and the water injection assembly 35 move in the up-down direction. Thus, there is no need to set a relatively large avoidance space in the horizontal direction for the movement of the dirt pumping assembly 33 and the water injection assembly 35, and the projection area of the base station body 31 on the horizontal plane can be set relatively small, that is, the occupation of the ground by the base station body 31 is reduced and the convenience of placing the base station body 31 is improved. Of course, the present application is not limited to this. In other embodiments, the dirt pumping assembly 33 and the water injection assembly 35 can be provided in the base station body 31 and slidable or rotatable in the horizontal direction, and can be butted with the host dirt collecting chamber 111 and the host clean water chamber 112 after sliding or rotating.
Referring to
It can be understood that the dirt pumping assembly 33 and the water injection assembly 35 are driven up and down by the driving member 37, thereby realizing automatic docking of the dirt pumping assembly 33 with the host dirt collection chamber 111 and automatic docking of the water injection assembly 35 with the host clean water chamber 112, thereby improving the degree of automation of docking of the cleaning robot 10 with the base station 30, and further improving the convenience of use of the cleaning system 100. Moreover, a small number of driving members 37 is set by simultaneously driving the dirt pumping assembly 33 and the water injection assembly 35 to lift or lower by one driving member 37, thereby reducing the manufacturing cost of the cleaning system 100. At the same time, the dirt pumping assembly 33 and the water injection assembly 35 are connected to one driving member 37, so that the distribution of the dirt pumping assembly 33 and the water injection assembly 35 can be more compact, and the required space is reduced. Of course, there can be two driving members 37 and the two driving members 37 are both provided in the base station body 31. One of the two driving members 37 can be connected to the dirt pumping assembly 33 and the other of the two driving members 37 can be connected to the water injection assembly 35. At this time, the dirt pumping assembly 33 and the water injection assembly 35 can be driven up and down by the two driving members 37 correspondingly. In addition, it should be noted that the present application is not limited to this. In other embodiments, a pull lever slidable in the up-down direction is provided on the base station body 31 of the base station 30, and the dirt pumping assembly 33 and the water injection assembly 35 are connected to one end of the pull lever. At this time, it is also possible for the user to manually drive another end of the pull lever away from the dirt pumping assembly 33 and the water injection assembly 35, to lift or lower the dirt pumping assembly 33 and the water injection assembly 35. In addition, in one embodiment, the base station body 31 is also provided with a button and/or a display screen. At this time, the user can input corresponding operation instructions through the button, so as to more conveniently control the base station 30 to carry out corresponding work, such as, the pause of the base station 30 after being started, the adjustment of a dirt pumping rate of the dirt pumping assembly 33, the adjustment of a water injection rate of the water injection assembly 55 or other control instructions. The working state of the base station 30 can be displayed to the user through the display screen (for example, working states such as pumping dirt from the cleaning robot 10, injecting water into the cleaning robot 10, a remaining clean water amount in the base station clean water chamber 303, an amount of garbage and sewage in the base station dirt collecting chamber 31a, a remaining amount of liquid detergent in the liquid detergent chamber, etc.), so that the user can more intuitively know the working state of the base station 30. Further, the display screen can be a touch screen, so that the user can input some instructions through the display screen.
Referring to
It can be understood that only the dirt pumping pipe 331 and the water injection pipe 351 are driven by the driving member 37 to rise or fall. Since the masses of the dirt pumping pipe 331 and the water injection pipe 351 are relatively light, the load on the driving member 37 can be reduced and the driving member 37 is facilitated to drive the dirt pumping pipe 331 and the water injection pipe 351. Of course, the present application is not limited thereto. In other embodiments, the driving member 37 can drive the dirt pumping pipe 331 of the dirt pumping assembly 33 and the dirt pumping fan that communicates with the dirt pumping pipe 331 to provide pumping power together. Likewise, the driving member 37 can drive the water injection pipe 351 of the water injection assembly 35 and the water pump connected with the water injection pipe 351 to provide water injection power together. When the base station body 31 is provided with the liquid detergent chamber, the front end of the water injection pipe 351 is communicated with the liquid detergent chamber.
Referring to
It can be understood that a rotational motion of an output shaft of the driving member 37 can be converted into a linear motion by the transmission assembly 39, thereby to drive the dirt pumping pipe 331 and the water injection pipe 351 up and down relative to the base station body 31. That is, the driving member 37 can be a motor at this time, and the transmission assembly 39 also prevents the motor's too fast rotation from affecting the stability of the dirt pumping pipe 331 and the water injection pipe 351 during the lifting process and the falling process, thereby further reducing of the possibility of collisions of the dirt pumping pipe 331 and the water injection pipe 351 during the docking process of the cleaning robot 10 with the base station 30. Of course, it should be noted that the present application is not limited thereto. In other embodiments, a cylinder is directly adopted as the driving member 37, and the dirt pumping pipe 331 and the water injection pipe 351 are directly connected to an telescopic end of the cylinder. In this case, the dirt pumping pipe 331 and the water injection pipe 351 can be directly driven to move up and down by the cylinder.
In one embodiment of the present application, the transmission assembly 39 includes a gear 391 and a rack 393, the gear 391 is sleeved on the output shaft of the driving member 37, the rack 393 is liftably provided on the base station body 31 and meshed with the gear 391, the dirt pumping pipe 331 and the water injection pipe 351 are connected to the rack 393.
It can be understood that when the transmission assembly 39 is composed of the gear 391 and the rack 393, since the transmission of the gear 391 and the rack 393 has the advantages of large bearing capacity and high precision, the gear 391 and the rack 393 can stably load the dirt pumping pipe 331 and the water injection pipe 351 while ensuring stability in driving the dirt pumping pipe 331 and the water injection pipe 351 up and down. In order to facilitate the connection between the rack 393 and the dirt pumping pipe 331 and the connection between the rack 393 and the water injection pipe 351, the rack 393 can connect with a mounting plate defined with two mounting holes, and the dirt pumping pipe 331 and the water injection pipe 351 are inserted in the two mounting holes correspondingly. Of course, the dirt pumping pipe 331 and the water injection pipe 351 may be connected to the rack 393 through hoops. In addition, it should be noted that the present application is not limited to this. In other embodiments, the transmission assembly 39 can also include a screw rod and a slide seat. The screw rod is rotatably provided on the base station body 31 and extended along a lifting direction and a falling direction of the dirt pumping pipe 331 and the water injection pipe 351. The slide seat can be liftably sleeved on an outer side of the screw rod, and connected with the dirt pumping pipe 331 and the water injection pipe 351. Alternatively, the transmission assembly 39 includes a driving wheel, a driven wheel and a belt, the driving wheel is sleeved on the output shaft of the driving member 37, the driven wheel is rotatably disposed on the base station body 31, and the belt is sleeved on the driving wheel and the driven wheel. At this time, the dirt pumping pipe 331 and the water injection pipe 351 can be connected to the belt.

It can be understood that the docking groove 31d is used to accommodate the cleaning robot 10 when the cleaning robot 10 and the base station 30 are docked, so that both the cleaning robot 10 and the base station 30 can be distributed more compactly when the cleaning robot 10 and the base station 30 are docked, thereby reducing the required space. At the same time, groove walls of the docking groove 31d can also play a certain role in limiting and guiding the cleaning robot 10, thereby facilitating the accurate docking of the cleaning robot 10 with the base station 30. Meanwhile, the driving member 37, the dirt pumping pipe 331, and the water injection pipe 351 are all disposed in the mounting chamber 31f, and walls of the mounting chamber 31f can protect the driving member 37, the dirt pumping pipe 331, and the water injection pipe 351 to a certain extent, thereby reducing the possibility of damage to the driving member 37, the dirt pumping pipe 331, and the water injection pipe 351 by foreign objects. The mounting chamber 31f may have a substantially square structure so that the shape of the mounting chamber 31f is more regular and facilitates molding and manufacturing. The shape of the docking groove 31d may be an arch shape so as to be adapted to the round-shaped cleaning robot 10. Of course, the docking groove 31d may have a square shape, and the specific shape of the docking groove 31d is not limited herein, as long as the cleaning robot 10 can be accommodated in the docking groove 31d. Further the docking groove 31d may accommodate a portion of the cleaning robot 10 or the whole of the cleaning robot 10. The docking groove 31d can specifically include a groove top wall, a groove bottom wall opposite to the groove top wall and a groove side wall connecting the groove top wall and the groove bottom wall. The end surfaces of the groove top wall, the groove bottom wall, and the groove side wall of the docking groove 31d near the opening of the docking groove 31d are on the same plane or on different planes. For example, the groove bottom wall can be protruded relative to the groove top wall and the groove side wall, so that the groove bottom wall can support the cleaning robot 10 sufficiently. In addition, it should be noted that the present application is not limited to this. In other embodiments, a bottom plate is protruded from the side wall of the base station body 31 near the bottom, and the bottom plate can support the cleaning robot 10 when the cleaning robot 10 and the base station 30 are docked.
In one embodiment of the present application, the mounting chamber 31f is provided with travel limiting mechanisms, which can limit travel distances of the dirt pumping pipe 331 and the water injection pipe 351 driven by the driving member 37 during the lifting process and the falling process.
It can be understood that the travel limiting mechanism can reduce the possibility of colliding with other objects caused by excessive lifting or lowering of the dirt pumping pipe 331 and the water injection pipe 351 by the driving member 37, so that the safety of the dirt pumping pipe 331 and the water injection pipe 351 during the up and down process can be improved. The travel limiting mechanism controls the driving member 37 through a controller provided on the base station body 31. For example, when the driving member 37 is a motor, the number of rotation turns of the motor can be controlled by the controller. Of course, the base station 30 may be provided with a limit switch, such as a touch switch or a proximity switch, to form the travel limiting mechanism. When the rack 393 of the transmission assembly 39 touches the touch switch during up or down to trigger a position signal, or approaches the proximity switch during up or down to trigger a position signal, the motor stops driving the gear 391 to rotate.
In one embodiment of the present application, a position sensor is provided in the docking groove 31d, and the position sensor is electrically connected to the driving member 37. The position sensor can detect whether the cleaning robot 10 is in place in the docking groove 31d.
It can be understood that it can detect whether or not the cleaning robot 10 is in place within the docking groove 31d through the position sensor, that is to say, whether or not the cleaning robot 10 reaches a preset docking position. Thereafter, the position signal of the cleaning robot 10 can be transmitted to the driving member 37, and the driving member 37 can be actuated and drives the dirt pumping pipe 331 and the water injection pipe 351 to fall according to the position signal. Thus, after the cleaning robot 10 is moved in place, the dirt pumping pipe 331 and the water injection pipe 351 can be lowered in time to communicate with the host dirt collecting chamber 111 and the host clean water chamber 112, thereby improving the efficiencies of dirt pumping and water injection. At the same time, the degree of automation of the base station 30 is further improved, and the operation of the driving member 37 is not manually controlled.
Referring to
Understandably, the position signal of the cleaning robot 10 moves in place is transmitted to the driving member 37 through the charging contact 113 abutting against the charging pole piece 311, not only that the automatic operation of the driving member 37 is realized, but also that the base station 30 is enabled to have a function of charging the cleaning robot 10, that is, the use function of the base station 30 is further improved, and the automatic charging of the cleaning robot 10 is realized without the user manually transporting the cleaning robot 10 to a charging place for charging. The charging pole piece 311 can be provided on the side wall of the docking groove 31d, or on the top wall or bottom wall of the docking groove 31d. The charging pole piece 311 can be correspondingly provided on the side wall, an upper surface or a lower surface of the robot body 11.
Referring to
It can be understood that the movement of the cleaning robot 10 into the docking groove 31d can be guided by the guiding structure 313 so that the cleaning robot 10 moves to the accurate position in the docking groove 31d and is limited. This also facilitates the accurate abutting and driving of a push lever 312 to a pressing seat 117, and prevents the push lever 312 from colliding with other components of the cleaning robot 10 and damaging the cleaning robot 10 due to misalignment of the push lever 312 to the pressing seat 117.
Refer to
It can be understood that since the cleaning robot 10 is provided with the moving wheel 15, the guiding groove 313a for accommodating and guiding the moving wheel 15 is defined on the groove bottom wall of the docking groove 31d to form the guiding structure 313, a structure of the guiding structure 313 is simplified. At the same time it is also made unnecessary to provide an additional structure on the cleaning robot 10 to form the guiding structure 313, thereby being also helpful for the simplification of the structure of the cleaning robot 10.
Referring to
It can be understood that the moving wheel 15 can be guided to move gradually and accurately into the limiting groove section by the guiding groove section 313b of the guiding groove 313a, thereby reducing the accuracy requirement for alignment between the moving wheel 15 and the limiting groove section, and facilitating the accurate alignment between the cleaning robot 10 and the base station 30. The moving wheel 15 can be limited by the limiting groove section of the guiding groove 313a, so that the moving wheel 15 can only be moved along the extending direction of the limiting groove section, so as to align with the base station 30 accurately afterward (such as the contact and alignment between the charging pole piece 311 and the charging contact 113). The distance between the two opposite groove side walls of the limiting groove section can be set to equal to the thickness of the moving wheel 15 of the cleaning robot 10, so that when the moving wheel 15 moves into the limiting groove section, the two opposite groove side walls of the limiting groove section can abut against two corresponding side wall surfaces of the moving wheel 15. Of course, the distance between the two opposite groove side walls of the limiting groove section can be greater than the thickness of the moving wheel 15, and a groove side wall of the limiting groove section can abut against a corresponding side wall surface of the moving wheel 15. In addition, it should be noted that in other embodiments, the guiding groove 313a may have only the limiting groove section. Alternatively, the guiding groove 313a may have only the guiding groove section 313b in which case the minimum distance between the two opposite groove side walls of the guiding groove 313a can be the same as the thickness of the moving wheel 15.
Referring to
It can be understood that the two driving wheels 151 and the one universal wheel 153 are triangular distributed, so that the robot body 11 can be stably supported with that the number of moving wheels 15 is relatively small, which is beneficial to reduce the manufacturing cost of the cleaning robot 10. The two driving wheels 151 can provide a driving force to drive the cleaning robot 10 to move. The universal wheel 153 enables the cleaning robot 10 to smoothly adjust its steering while moving, thereby facilitating the docking efficiency of the cleaning robot 10 in the docking groove 31d. Of course, the present application is not limited thereto and in other embodiments, the number of the moving wheels 15 may be four or more. The numbers of the driving wheels 151 and the universal wheels 153 can be adaptively arranged as required. Alternatively, the moving wheels 15 may be composed only of the driving wheels 151 and an ordinary one-way wheel.
Referring to
It can be understood that when the cleaning robot 10 moves to the docking groove 31d for docking, the side wall of the cleaning robot 10 can be abutted against, limited and guided by the roller 315, so as to guide the cleaning robot 10 to accurately move to the preset docking position. There can be only one or both of the two opposite groove side walls of the docking groove 31d provided with the roller(s) 315. In addition, in an embodiment, after the guiding groove 313a is provided on the groove bottom wall of the docking groove 31d, rollers 315 are also provided on the two opposite groove side walls of the docking groove 31d, that is, the arrangement of the guiding groove 313a is in combination with the arrangement of the rollers 315.
Referring to
It can be understood that the cleaning robot 10 moves to various positions when cleaning the ground. Therefore, the infrared signal sent by the infrared emitter 317 on the base station body 31 is received by the infrared receiver on the cleaning robot 10, and a preliminary positioning of the base station 30 can be obtained by the cleaning robot, so as to facilitate it to quickly approach the base station 30 and accurately dock with the base station 30 by accurate positioning through the guiding groove and/or the roller 315. That is, after the guiding groove 313a is provided on the groove bottom wall of the docking groove 31d and/or the roller(s) 315 is/are provided on the opposite side walls of the docking groove 31d, an infrared emitter 317 can be further provided on the base station body 31, and an infrared receiver can be provided on the robot body 11.
Referring to
It can be understood that the accommodating chamber 31h provides an accommodating space for the infrared emitter 317, which makes it be compactly installed on the base station body 31, and the possibility that the infrared emitter 317 interferes with the cleaning robot 10 when the cleaning robot 10 and the base station 30 are docked is reduced. At the same time, walls of the accommodating chamber 31h also protect the infrared emitter 317 to a certain extent, so that the possibility of damage to the infrared emitter 317 can be reduced. In addition, it should be noted that the present application is not limited thereto and there can be two or more infrared emitters 317 to provide multiple alignment directions for the infrared receiver to receive positioning of the base station 30.
Referring to
It can be understood that the arrangement of the guiding slope reduces a height to the ground, and can reduce the trouble to the cleaning robot 10 entering the docking groove 31d due to the height of the end of the groove bottom wall of the docking groove 31d where the guiding slope is formed, thereby improving the smoothness of the cleaning robot 10 entering the docking groove 31d. Of course, the present application is not limited to this. In other embodiments, it is also possible that everywhere of the groove bottom wall of the docking groove 31d except the guiding groove 313a is located on the same plane. In this case, the thickness of the groove bottom wall of the docking groove 31d can be reduced.

The cleaning brush 13 is configured for cleaning the ground, and can be a roller brush or a mop. Since garbage is attached to the cleaning brush 13 after cleaning the ground, and the cleaning brush 13 is cleaned by the first cleaning assembly 50, it does not need the user to manually clean the cleaning brush 13, and is beneficial to further improve the function of the base station 30 and improve the convenience of using the base station 30. The cleaning of the cleaning brush 13 can include combing the bristles of the cleaning brush 13 and cleaning the garbage wrapped on the cleaning brush 13.
Referring to
It can be understood that the cleaning brush 13 can be brought into contact with the plurality of first cleaning columns 51 during rotation. Since the plurality of first cleaning columns 51 have a blocking effect, the bristles of the cleaning brush 13 can only pass through gaps between the plurality of first cleaning columns 51, thereby realizing combing of the bristles of the cleaning brush 13. At the same time, by the blocking action of the first cleaning columns 51, the elongated garbage wrapped on the cleaning brush 13 can be blocked and limited so as to be separated from the cleaning brush 13. Each first cleaning column 51 has a columnar structure and can be a cylinder or a square column or another columnar structure. Each first cleaning column 51 can be provided with a blade in order to cut off the elongated garbage and reduce the possibility that the garbage is still wrapped on the cleaning brush 13 and affects the normal operation of the cleaning robot 10.
Of course, the present application is not limited thereto, referring to
It can be understood that during the rotation of the cleaning brush 13, since each first cleaning hook 53 has a hook-shaped structure, the elongated garbage wrapped on the cleaning brush 13 can be hooked by the plurality of first cleaning hooks 53 and separated from the cleaning brush 13, thereby realizing cleaning of the cleaning brush 13. The first cleaning assembly 50 can include only the plurality of first cleaning columns 51, or only the plurality of first cleaning hooks 53, or both the plurality of first cleaning columns 51 and the plurality of first cleaning hooks 53. Alternatively, in another embodiment, the first cleaning assembly 51 can also include an elongated scraper by which garbage on the rotating cleaning brush 13 can be scraped off. Alternatively, when the cleaning brush 13 is a mop, the first cleaning assembly 51 can be a movable cleaning block for cleaning the mop.
Referring to
It can be understood that the groove 31e can avoid the cleaning brush 13 to a certain extent, so that the cleaning brush 13 can be driven to rotate by a motor connected to the cleaning brush 13 and provided on the robot body 11 during the self-cleaning process, thereby effectively cleaning the cleaning brush 13 in the circumferential direction. At this time, the first cleaning assembly 50 may be disposed in the groove 31e. In order to further improve the cleaning effect of cleaning the cleaning brush 13, referring to

Referring to
Understandably, the dirt pumping assembly 33 and the water injection assembly 35 are communicated with the dirt pumping port 11a and the water injection port 11b correspondingly, dirt pumping and water injection of the cleaning robot 10 are realized, so that the dirt pumping assembly and the water injection assembly do not need to be inserted into the host dirt collecting chamber 111 and the host clean water chamber 112, thereby reducing the requirement for up and down movement of the dirt pumping assembly and the water injection assembly, facilitating the docking and communication between the dirt pumping assembly and the water injection assembly and the cleaning robot 10, and improving the docking efficiency. The dirt pumping pipe 331 and the water injection pipe 351 are driven down by the driving member 37 of the base station 30 so as to communicate with the dirt pumping port 11a and the water injection port 11b correspondingly. In addition, it should be noted that the present application is not limited to this. In other embodiments, it is also possible for the dirt pumping pipe 331 of the dirt pumping assembly 33 and the water injection pipe 351 of the water injection assembly 35 to be inserted into the host dirt collecting chamber 111 and the host clean water chamber 112 correspondingly, for docking.
Referring to
It can be understood that when the cleaning robot 10 moves close to the base station 30, the push lever 312 moves relative to the cleaning robot 10 and abuts against and drives the cover plate 114 to open the dirt pumping port 11a and the water injection port 11b. Thus, the user does not need to manually open the cover plate 114 before docking, thereby further improving the automation of docking of the cleaning robot 10 and the base station 30, and improving the convenience of using the cleaning system 100. Also, when the cleaning robot 10 cleans the ground, the dirt pumping port 11a and the water injection port 11b are always covered by the cover plate 114, and the cover plate 114 is opened only when the cleaning robot 10 is docking with the base station 30 to realize dirt pumping and water injection of the cleaning robot 10. The possibility of external dust or sundries falling into the host dirt collecting chamber 111 and the host clean water chamber 112 via the dirt pumping port 11a and the water injection port 11b correspondingly is reduced, thus the cleaning robot 10 can work normally and stably. After the base station body 31 is formed with the docking groove 31d, the push lever 312 can be provided on the groove side wall of the docking groove 31d facing the opening of the docking groove 31d. Of course, the present application is not limited to this, in other embodiments, the push lever 312 can be provided directly on a side surface of the base station body 31, in which case the dirt pumping assembly 33 and the water injection assembly 35 can also be provided directly on the side surface of the base station body 31. In addition, if the push lever 312 is not provided on the groove side wall of the docking groove 31d, the cover plate 114 can be opened manually by the user before the cleaning robot 10 is docked with the base station 30.
Referring to
It can be understood that the cover plate 114 is rotatably provided on the robot body 11, so that a movement trajectory of the cover plate 114 is arc-shaped, and the change of the position of the cover plate 114 is relatively small during the contact and driving process by the push lever 312, thereby reducing the possibility of interference between the cover plate 114 and other components on the robot body 11 after being driven. Of course, the present application is not limited to this. In other embodiments, the cover plate 114 can be provided on an upper surface of the robot body 11 and slidable in the horizontal direction, and the cover plate 114 can open or close the dirt pumping port 11a and the water injection port 11b when sliding with respect to the robot body 11.
Referring to
It can be understood that the push lever 312 abuts against and drives the pressing seat 117, and then the pressing seat 117 abuts against and drives the eccentric shaft 116, thereby realizing that the push lever 312 indirectly drives the rotating shaft 115 through the eccentric shaft 116. Thus, a relatively complex abutment structure between the push lever 312 and the rotating shaft 115 is not required, and a relatively deep insertion of the push lever 312 into the cleaning robot 10 is not required, thereby facilitating the simplification of the arrangement of the push lever 312. Moreover, since the pressing seat 117 slides along the extension direction of the push lever 312, it is possible to ensure that the pressing seat 117 and the push lever 312 are not separated during the docking process, thereby achieving to stably and effectively contact and drive the pressing seat 117 and further to stably and effectively contact and drive the eccentric shaft 116 through the pressing seat 117. The eccentric shaft 116 and the rotating shaft 115 may be directly connected to make the connection more compact. Of course, the eccentric shaft 116 and the rotating shaft 115 can be indirectly connected, that is, the eccentric shaft 116 and the rotating shaft 115 can be connected to opposite ends of a connecting lever. In addition, in one embodiment, the axis of the eccentric shaft 116 and the axis of the rotating shaft 115 can be arranged in parallel, so that the abutting and driving force applied to the eccentric shaft 116 can be perpendicular to the axis of the rotating shaft 115, thereby facilitating the rotation of the rotating shaft 115. Of course, the present application is not limited to this, the axis of the eccentric shaft 116 and the axis of the rotating shaft 115 can intersect.
Referring to
It can be understood that the eccentric shaft 116 is fixed by the first cylindrical portion 1161 being sleeved on the rotating shaft 115, so that a contact area between the first cylindrical portion 1161 and the rotating shaft 115 is increased and the stability of the connection between the first cylindrical portion 1161 and the rotating shaft 115 is improved. Furthermore, the first cylindrical portion 1161 is sleeved on and connected to the rotating shaft 115, the connection structure between the first cylindrical portion 1161 and the rotating shaft 115 is simple, that is, only an insertion hole is needed to be defined on the first cylindrical portion 1161 for receiving the rotating shaft, thereby facilitating the simplification of the structure of the eccentric shaft 116 and the rotating shaft 115. In order to reduce the possibility of slipping of the eccentric shaft 116 and the first cylindrical portion 1161 relative to each other, the insertion hole in the first cylindrical portion 1161 and the rotating shaft 115 inserted in the insertion hole can be provided with rotation stop structures. For example, the circumferential surface of the rotating shaft 115 fitted into the first cylindrical portion 1161 can be defined with a rotation stop flat surface, and the insertion hole in the first cylindrical portion 1161 can be provided with a rotation stop mating surface abutting against the rotation stop flat surface. Alternatively, the circumferential surface of the rotating shaft 115 embedded in the first cylindrical portion 1161 is provided with a rotation stop rib, and a rotation stop groove for receiving the rotation stop rib is defined on a wall of the insertion hole of the first cylindrical portion 1161. The second cylindrical portion 1163 increases an eccentric distance between an axis of the abutment column 1163 and the axis of the rotating shaft 115, thereby facilitating the abutment column 1163 of the eccentric shaft 116 to rotate the rotating shaft 115 of the cover plate 114 and open the dirt pumping port 11a and the water injection port 11b when being driven by the pressing seat 117. The first cylindrical portion 1161, the second cylindrical portion 1163 and the abutment column 1163 can be formed as an integral structure. Of course, it should be noted that the present application is not limited to this. In other embodiments, the eccentric shaft 116 can only include the second cylindrical portion 1163, in which case the second cylindrical portion 1163 can be connected to the rotating shaft 115 through a connecting plate.
Referring to
It can be understood that a movement space for the abutment column 1163 to move is formed between the two bumps 1171, so that the connection structure between the pressing seat 117 and the abutment column 1163 is simplified, thereby facilitating the simplification of the structures of the both and reducing the manufacturing cost. At the same time, when to assemble the pressing seat 117 and the abutment column 1163 together, the abutment column 1163 can be directly inserted from an opening between the two bumps 1171 away from the pressing seat 117, thereby improving the assembly efficiency of the pressing seat 117 and the abutment column 1163. Of course, the present application is not limited to this. In other embodiments, an arc-shaped groove can be defined in a side wall of the pressing seat 117 facing the rotating shaft 115, and an end of the abutment column 1163 away from the second cylindrical portion 1163 can be inserted into the arc-shaped groove. At this time, when the pressing seat 117 is driven by the push lever 312, the abutment column 1163 can move in the arc-shaped groove.
Referring to
It will be understood that when the pressing seat 117 is driven by the push lever 312, the elastic member 118 is compressed to deform and produce a corresponding rebounding force. After that, when the cleaning robot 10 completes dirt pumping, water injection and self-cleaning and is far away from the docking area of the base station 30, the push lever 312 doesn't abut against the pressing seat 117, the elastic member 118 drives the pressing seat 117 to reset under the action of the rebounding force, and the pressing seat 117 drives the abutment column 1163 to make the rotating shaft 115 of the cover plate 114 rotate and reset, thereby realizing automatically closing the cover plate 114. since the push lever 312, the pressing seat 117, the eccentric shaft 116, and the elastic member 118 are all relatively simple mechanical structures, the automatic opening and closing of the cover plate 114 is realized by only mechanical structures, which have the advantage of safety and reliability. The elastic member 118 can be a spring so that the elastic member 118 has relatively good elasticity while the cost is low. Of course, the elastic member 118 can be a plastic member having certain elasticity. In addition, in order to further improve the stability of opening and closing of the cover plate 114, two push levers 312 can be provided. In this case, both opposite sides of the cover plate 114 are provided with a rotating shaft 115, the rotating shaft 115 is connected with an eccentric shaft 116, and two pressing seats 117 are provided correspondingly, so that one push lever 312 abuts against and drives one pressing seat 117, and drives the eccentric shaft 116 through the pressing seat 117 to drive the rotating shaft 115 to rotate.
Referring to
It can be understood that the mounting groove 11c provides an accommodating space for the cover plate 114, so that the cover plate 114 can be more tightly mounted on the robot body 11. At the same time, it is also helpful to make the transition between the cover plate 114 and the upper surface of the robot body 11 more smooth, and reduce the possibility that the cover plate 114 is damaged due to collision with obstacles during the movement of the cleaning robot 10. The sliding chamber 11d provides an accommodating space for the eccentric shaft 116, the pressing seat 117, and the elastic member 118, so that the three can be installed more compactly and occupy less space. At the same time, the wall of the sliding chamber 11d protects the eccentric shaft 116, the pressing seat 117, and the elastic member 118 to a certain extent, thereby reducing the possibility that the eccentric shaft 116, the pressing seat 117, and the elastic member 118 are damaged by foreign objects. When there are two eccentric shafts 116, two pressing seats 117, and two elastic member 118, two sliding chambers 11d are respectively provided on opposite sides of the cover plate 114. It should be noted that the present application is not limited thereto, and in other embodiments, the cover plate 114, the eccentric shaft 116, the pressing seat 117, and the elastic member 118 can be provided directly on the upper surface of the robot body 11.

The cleaning brush 13 is configured for cleaning the ground, and can be a roller brush or a mop. Since garbage is attached to the cleaning brush 13 after cleaning the floor, and the cleaning brush 13 is cleaned by the second cleaning assembly 70, it does not need the user to manually clean the cleaning brush 13, and is beneficial to further improve the function of the cleaning robot 10 and improve the convenience of using the cleaning robot 10. The cleaning of the cleaning brush 13 can be combing the bristles of the cleaning brush 13 and cleaning the garbage (e.g., hair or other elongated garbage) wrapped on the cleaning brush 13.
Referring to
It can be understood that the cleaning brush 13 can be brought into contact with the plurality of second cleaning columns 71 during rotation. Since the plurality of second cleaning columns 71 have a blocking effect, the bristles of the cleaning brush 13 can only pass through gaps between the plurality of second cleaning columns 71, thereby realizing combing of the bristles of the cleaning brush 13. At the same time, by the blocking action of the second cleaning columns 71, the elongated garbage wrapped on the cleaning brush 13 can be blocked and limited so as to be separated from the cleaning brush 13. Each second cleaning column 71 has a columnar structure and can be a cylinder or a square column or another columnar structure. Each second cleaning column 71 can be provided with a blade in order to cut off the elongated garbage and reduce the possibility that the garbage is still wrapped on the cleaning brush 13 and affects the normal operation of the cleaning robot 10.
Of course, the present application is not limited thereto. In another embodiment of the present application, referring to
It can be understood that during the rotation of the cleaning brush 13, since each second cleaning hook 73 has a hook-like structure, the elongated garbage wrapped on the cleaning brush 13 can be hooked by the plurality of second cleaning hooks 73 and separated from the cleaning brush 13, thereby realizing cleaning of the cleaning brush 13. The second cleaning assembly 70 can include only the plurality of second cleaning columns 71, or only the plurality of second cleaning hooks 73, or both the plurality of second cleaning columns 71 and the plurality of second cleaning hooks 73. Alternatively, in another embodiment, the second cleaning assembly 70 can also include an elongated scraper by which garbage on the rotating cleaning brush 13 can be scraped off. Alternatively, when the cleaning brush 13 is a mop, the second cleaning assembly 70 can be a movable cleaning block for cleaning the mop. Further, in order to further improve the cleaning effect of cleaning the cleaning brush 13, a host nozzle 11g provided on the robot body 11 and communicated with the host clean water chamber 112 can face the cleaning brush 13. Thus, by opening the host nozzle 11g, the cleaning brush 13 can be sprayed with water, so that the cleaning brush 13 can be sprayed with water and cleaned during the docking process of the cleaning robot 10 with the base station 30, and can be wet to mopping the ground when the cleaning robot 10 cleans the ground. Of course, the present application is not limited to this, in other embodiments, the host nozzle 11g provided on the robot body 11 and communicated with the host clean water chamber 112 can face the ground directly.
Further it should be noted that for the cleaning system 100 of the present application, it can be that only the first cleaning assembly 50 is provided on the base station 30 for cleaning the cleaning brush 13, or only the second cleaning assembly 70 is provided on the cleaning robot 10 for cleaning the cleaning brush 13, or, both the first cleaning assembly 50 is provided on the base station 30 and the second cleaning assembly 70 is provided on the cleaning robot 10 for cleaning the cleaning brush 13.
The above is only an optional embodiment of the present application, and is not therefore limiting the patent scope of the present application. Any equivalent structural transformation made by using the contents of the present specification and drawings, or any direct/indirect application in other related technical fields, under the inventive concept of the present application, is included in the patent scope of the present application.
