The present disclosure claims priorities to Chinese Patent Application No. 202111221003.4 filed on Oct. 20, 2021, and Chinese Patent. Application No. 202210022939.2 filed on Jan. 10, 2022, which are hereby cited in their entireties as a part of this application.
The present disclosure relates to the field of cleaning device technologies, and particularly, to a cleaning brush and an intelligent cleaning device.
A cleaning brush is an important functional part of a cleaning device. An end cover of the cleaning brush is used to block an entanglement such as hairs or silk threads wound during a working process of the cleaning device, so as to avoid the phenomenon of jamming of a power output end and a bearing end of a motor due to entanglement because of excessive extension of the entanglement to the end of the cleaning brush.
As an intelligent household appliance, a sweeping robot plays an increasingly important rote in people's daily lives. The sweeping robot generally includes a dust suction system, a walking system and a power supply system. The dust suction system is used to collect dust on the ground, the walking system is used to drive the sweeping robot to move, and the power supply system is used to supply energy to the dust suction system and the walking system to work. An end cover of the existing cleaning brush has a relatively small size, such that a longer end of a shaft rod of the cleaning brush is exposed outside the end cover; and the end cover is located outside a cylindrical member sleeving a shaft cover of the cleaning brush. Consequently, it is easy for an entanglement wound around the cylindrical member to wind from the end of the cylindrical member to the end of the shaft rod, resulting in a relatively deep entangling position. In addition, the end cover must be detached to remove the entanglement from the inside of the cylinder member, which is laborious. In addition, due to the relatively small size of the end cover of the existing cleaning brush, it is difficult to find the missing installation of the end cover of the cleaning brush in the assembly process, so it is necessary to provide a responsible missing-installation prevention structure.
The present disclosure adopts the following technical solutions.
According to an aspect of the present disclosure, a cleaning brush is provided. The cleaning brush includes a shaft rod, a cylindrical member and at least one end member, wherein the shaft rod is provided with two first ends opposite in an axial direction; the cylindrical member coaxially sleeves the shaft rod and is provided with two second ends opposite in an axial direction, and a brush piece is arranged on an outer surface of the cylindrical member; the at least one end member is installed on at least one of the first ends, and the end member is provided with a blocking structure used for preventing an entanglement from excessively extending away from the cleaning brush; the end member and the first end are provided with installation structures matching each other respectively; and the second end of the cylindrical member, which corresponds to the end member, covers at least a portion of the end member.
According to another aspect of the present disclosure, an intelligent cleaning device is provided. The intelligent cleaning device includes a cleaning brush, wherein the cleaning brush includes a shall rod, a cylindrical member and at least one end member, wherein the shaft rod is provided with two first ends opposite in an axial direction; the cylindrical member coaxially sleeves the shaft rod and is provided with two second ends opposite in an axial direction, and a brush piece is arranged on an outer surface of the cylindrical member; the at least one end member is installed on at least one of the first ends, and the end member is provided with a blocking structure used for preventing an entanglement from excessively extending away from the cleaning brush; the end member and the first end are provided with installation structures matching each other respectively; and the second end of the cylindrical member, which corresponds to the end member, covers at least a portion of the end member.

Based on the design of the spiral shape of the limiting rib 432 and the limiting groove 431, in one implementation of the present disclosure, a spiral direction of the spiral limiting rib 432 and the spiral limiting groove 431 may be opposite to a rotation direction of the shaft rod 100. With the above design, in a case that the shaft rod 100 rotates in the cleaning device in a rotation direction, the limiting rib 432 can be further prevented from being disengaged from the limiting groove 431 as the spiral direction of the limiting rib 432 and the limiting groove 431 is opposite to this rotation direction, thereby ensuring the installation stability and reliability of the shaft rod 100 and the end members 300.

In some implementations, the brush piece may also be a blade, bristles or in other forms.
It should be noted herein that the cleaning brush shown in the drawings and described in the present description is only a few examples of many types of cleaning brushes capable of adopting the principles of the present disclosure. It should be clearly understood that the principles of the present disclosure are in no way limited to any detail or any part of the cleaning brush shown in the drawings or described in the present description.
For example:

In an implementation of the present disclosure, one end of the guide shaft of one of the end members, which is away from the shaft rod, extends out of the end member and serves as a matching section matching the bearing structure; and the bearing structure is detachably arranged on the matching section of the guide shaft.
In an implementation of the present disclosure, the matching section is provided with a positioning groove in a circumferential direction, the positioning groove cooperating with the bearing structure by fixing each other's positions to prevent the bearing structure from displacing.
In an implementation of the present disclosure, the cylindrical member may be a flexible member or a rigid member.
Based on the above detailed description of several exemplary implementations of the cleaning brush proposed in the present disclosure, an exemplary implementation of the intelligent cleaning device proposed in the present disclosure will be described below.
In one implementation of the present disclosure, the intelligent cleaning device proposed in the present disclosure includes a cleaning brush proposed in the present disclosure and detailed in the above implementations.
It should be noted herein that the intelligent cleaning device shown in the drawings and described in the present description is only a few examples of many types of intelligent cleaning device capable of adopting the principles of the present disclosure. It should be clearly understood that the principles of the present disclosure are in no way limited to any detail or any part of the intelligent cleaning device shown in the drawings or described in the present description.
In summary, the cleaning brush purposed by the present disclosure includes the shaft rod 100, the cylindrical member 200 and the end members 300. Each end member 300 is installed on the first end 110 of the shaft rod 100. Each end member 300 is provided with the blocking structure 310 for preventing an entanglement from excessively extending away from the cleaning brush. The end member 300 and the first end 110 are provided with installation structures 400 matching each other respectively. The second end 210 of the cylindrical member 200, which corresponds to the end member 300, covers at least a portion of the end member 300. With the above design, in the present disclosure, at least part of the end member 300 intervenes between the shaft rod 100 and the corresponding end of the cylindrical member 200, avoiding an entanglement wound on the cylindrical member 200 from being wound to the shaft rod 100. Instead, the entanglement is wound on the end member 300 and can thus be removed with the disassembly of the end member 300, such that cleaning is more convenient.
Generally, a sweeping robot includes a housing, a cleaning brush and a cleaning brush cover. The cleaning brush is arranged in the housing, and the cleaning brush cover covers the housing. In addition, the cleaning brush cover is provided with a dust suction opening that allows the cleaning brush to contact the ground. The cleaning brush adsorbs dust for cleaning through the dust suction opening when rotating. However, it is difficult for traditional cleaning brushes to clean slender garbage such as hairs, especially short hairs on the ground, which are even more difficult to clean thoroughly.
In order to overcome the above problems, the present disclosure further provides a cleaning brush used to sweep garbage on the ground, such as dust or hairs, by means of rotation. Referring to
In actual use, the main brush body 1001 sweeps the ground by means of rotation. Specifically, referring to
In the sweeping process, slender garbage such as hairs will contact the blades 2001, and driven by the blades 2001 to rotate. However, in the rotation process of the main brush body 1001, the spiral blades 2001 can play a guide role to drive the garbage to slide to two ends of the main brush body 1001 along the blades 2001, in particular, two ends of the blades 2001, such that the cleaning brush guides this type of garbage to two ends of the main brush body 1001 for collection.
In the process of sweeping the ground, the wool strips 3001 on the blades 2001 can have the following two functions in the sweeping process:
The wool strips 3001 are combined to the blades 2001 on the cleaning brush. The plurality of bristles 3101 contact the ground and leave the short hairs on the wool strip 3001 while the cleaning brush rotates and sweeps the ground, till the short hairs are sucked away by the sweeping robot, thereby effectively cleaning up the short hairs on the ground and improving the sweeping quality.
In summary, according to the cleaning brush for a cleaning device in this embodiment of the present disclosure, the blades 2001 spirally distributed on the surface of the main brush body 1001 can guide slender-strip-shaped garbage such as hairs on the ground to travel to two ends of the main brush body 1001 while rotating and sweeping the ground, and at the same time cooperate with the wool strips 3001 on some of the blades 2001. The plurality of bristles 3101 on the wool strips 3001 rub against the ground to generate static electricity, and shorter hairs are adsorbed onto the bristles 3101 by means of the static electricity, such that hairs of all lengths on the ground can be effectively cleaned up, thereby improving the sweeping quality.
It should be mentioned that in the cleaning brush of this embodiment, the fixation of the blades to the surface of the cleaning brush in a spiral shape along the axial direction of the cleaning brush may be implemented by the following two ways:
Referring to
In other embodiments, the blades 2001 may also be discontinuous (not shown in the figure), that is, the blades 2001 on the main brush body 1001 do not extend from one end of the main brush body 1001 to the other end of the main brush body 1001. Instead, the blades 2001 on the main brush body 1001 may extend from the end of the main brush body 1001 to the middle of the main brush body 1001, and the two adjacent blades 2001 extend from two opposite ends and extend to the middle of the main brush body 1001. In this embodiment, slender garbage such as hairs can still slide to the two ends of the main brush body 1001 by contacting the spiral blades 2001 so as to achieve the purpose of sweeping all garbage on the ground.
In the sweeping process, as the main brush body 1001 rotates, specifically, referring to
In actual use, the cleaning brush will rotate in a direction opposite to the inclination direction of the blades 2001. During the rotation process, the cleaning surface 2101 will directly contact the ground and take the garbage on the ground up. Dust and other fine garbage will be sucked into the sweeping robot in the rolling process of the main brush body 1001, while a part of hairs and other slender garbage cannot be sucked away to form residual garbage, which may move to the two ends of the blades 2001 along the blades 2001. Referring to
It should be mentioned that the inclined blades 2001 can better make the cleaning surface 2101 and the ground fully contact during the rotation of the main brush body 1001, and sweep dust, hairs and other garbage, thereby improving a sweeping effect.
It should be mentioned that the blades 2001 fixed spirally have a limited effect on guiding slender garbage such as hairs merely relying on its guiding role. In order to further improve the effect of sweeping slender garbage such as hairs, the sweeping surfaces 2101 of part of the blades 2001 are provided with a plurality of salient points 2201; and the sweeping surfaces of the other part of the blades 2001 are fixedly connected to the wool strips 3001.
On the sweeping surfaces 2101 provided with the salient points 2201, the plurality of the salient points 2201 is arranged in an extension direction of the blades 2001. The salient points 2201 are arranged such that the salient points 2201 can guide hairs and other slender garbage in the process that the hairs and other slender garbage move on the surfaces of the blades 2001. Specifically, the main brush body 1001 rotates to drive the plurality of blades 2001 to alternately contact the ground and sweep the garbage up, and the garbage will contact the salient points 2201 in the movement process while the hairs and other slender garbage are swept up.
Firstly, the salient points 2201 can block the garbage, preventing the garbage from falling out of the blades 2001 and re-scattering to the ground.
Secondly, the garbage is in direct contact with the salient points 2201 during the movement process, and the salient points 2201 can guide the garbage, thereby guiding the garbage to move along edges of the salient points 2201, and in cooperation with the spiral blades 2001, making the garbage move to the two ends of the main brush body 1001 for collection and cleaning up as the main brush body 1001 rotates.
It can be seen from the foregoing that the blades 2001 will directly contact and collide with the ground during rotation, and in the process of contact and collision with the ground, a lot of noise will be generated. Therefore, the blades 2001 includes first blades 2011 and second blades 2021, and on the cross-section of the main brush body 1001, the length of the first blade 2011 is less than the length of the second blade 2021. With this design, the noise generated by the cleaning brush while sweeping the ground is reduced, and the user experience is improved.
Specifically, in the sweeping process, hairs and other slender garbage will contact the first blades 2011 and the second blades 2021 first, and the first blades 2011 and the second blades 2021 drive the garbage to rotate. However, as the main brush body 1001 rotates, due to a length difference between the first blade 2011 and the second blade 2021, a contact amplitude between the first blade 2011 and the ground is different from a contact amplitude between the second blade 2021 and the ground, and the noise generated by the contact of the first blade with the ground is different from the noise generated by the contact of the second blade with the ground. Specifically, the shorter first blades 2011 will produce less noise when contacting the ground. By disposing the first blades 2011 and the second blades 2021, which are not fixed in length, on the surface of the main brush body 1001, the noise generated by the cleaning brush while sweeping the ground is reduced, thereby improving the user experience.
In addition, the main brush body 1001 will also bring vibration to the first blades 2011 and the second blades 2021 in the rotation process, and the vibration of the shorter first blades 2011 will generate less noise than the longer second blades 2021.
In contrast, a sweeping effect of the second blades 2021 will be better than that of the first blades 2011, so the cleaning effect will be sacrificed if the shorter blades 2001 are used in order to reduce noise. Therefore, the wool strips 3001 are merely fixedly connected to the first blades 2011, Thus, the cleaning effect on the ground can be ensured while the noise caused by the cleaning brush during the rotation process is reduced.
Further, the adjacent first blades 2011 and second blades 2021 are arranged equidistantly. The first blades 2011 and the second blades 2021, which are spaced apart from one another, are arranged equidistantly, and such an equidistant arrangement can stabilize the entire cleaning brush in the rotation process, and make the working process of the entire sweeping robot smoother, thereby improving the cleaning effect.
In addition, the stable working state can reduce the operating vibration of the entire sweeping robot to a minimum, thereby effectively reducing the noise generated by the sweeping robot in actual work.
The first blades 2011 collide with and contact the ground with the rotation of the main brush body 1001, and the first blades 2011 will be more easily damaged than the second blades 2021 in long-term use due to their smaller length. Therefore, further, the thickness of the first blade 2011 is greater than the thickness of the second blade 2021. By increasing the thickness of the first blade 2011, the strength of the first blade 2011 can be improved, thereby avoiding the first blade 2011 from being damaged in actual use. In addition, the increase in the thickness of the first blades 2011 can also reduce the vibration of the first blades 2011, thereby reducing the noise generated by the first blades 2011 during rotation.
Specifically, the thickness of the first blade 2011 may be twice the thickness of the second blade 2021. This implementation is only one embodiment of the cleaning brush of the present disclosure, and the remaining embodiments in which the thickness of the first blade 2011 is greater than the thickness of the second blade 2021 shall be deemed to be within the scope covered by the present disclosure.
It should be mentioned that, referring to
In order to improve the sweeping effect and achieve better efficient cleaning of the ground, further, a plurality of bristles 3101 is arranged on the surface of a cylinder in a matrix. The plurality of bristles 3101 can improve the sweeping effect, such that the ground can be swept by the plurality of bristles at the same time while the blades 2001 contact the ground. In addition, the plurality of bristles 3101 arranged in the matrix can more effectively make sweeping effects of various areas on the wool strip 3001 consistent. When the blades 2001 sweep the ground, each area on the whole blade 2001 can effectively clean the ground, thereby improving the sweeping effect.
In the above embodiments, it should be mentioned that the bristles 3101 include hard plastic. The bristles made of the hard plastic 3101 can better rub against the ground to generate static electricity, so as to more effectively adsorb short hairs on the ground to multiple brush hairs, thereby sweeping the ground.
Correspondingly, the sweeping robot is provided with a driving mechanism for driving the entire cleaning brush to rotate. In order to be connected with the driving mechanism, the cleaning brush also includes a main brush shaft 4001. Referring to
Therefore, when the end cover 4201 of the main brush shaft connected to the driving mechanism 4201 has a failure, it is only necessary to disassemble the damaged end cover 4201 and replace it with another end cover 4201, instead of replacing the entire main brush shaft 4001, thereby achieving high convenience in use and reducing the user's use cost.
It should be mentioned that, referring to
The end cover 4201 directly sleeves the main shaft 4101 to realize the installation with the main shaft 4101. The installing groove 42111 of the end cover 4201 and the main shaft 4101 cooperate with each other and can constrain each other in position, so that relative positions of the end cover 4201 and the main shaft 4101 in a radial direction are unchanged. After the two end covers 4201 are installed at two ends of the main shaft 4101 respectively, the entire main brush shaft 4001 is installed in the overall structure of the sweeping robot, and connected to the driving mechanism, so as to output a torque through the driving mechanism and drive the main shaft 4101 to rotate; thereby driving the main brush body 1001 installed on the main shaft 4101 to rotate and sweeping the garbage on the ground by the main brush body 1001.
During the installation process, the barrel body 4211 of the end cover 4201 is used for installation and connection with the entire main shaft 4101, while one end of the connecting shaft 4221 inserted in the barrel body 4211 is connected to the main shaft 4101, and the other end of the connecting shaft 4221 is connected to the driving mechanism of the sweeping robot. It should be mentioned that one of the end covers 4201 at two ends is connected to the driving mechanism, and the other end cover is rotatably connected to the entire structure of the sweeping robot directly. In the actual use process, the torque is output through the driving mechanism; then the power is transmitted to the main shaft 4101 through the connecting shaft 4221, and the main brush body 1001 installed on the main shaft 4101 is driven further to rotate, such that the garbage on the ground is cleaned up through the main brush body 1001.
Further, referring to
Moreover, referring to
Further, in order to make the assembled structure more stable to improve the working stability of the entire cleaning brush, referring to
Further, in order to be connected with the driving mechanism on the sweeping robot, referring to
It should be mentioned that in the main brush shaft 4001 according to this embodiment of the present disclosure, the barrel body 4211, the connecting shaft 4221 and the main shaft 4101 are coaxially arranged. By means of the coaxial arrangement, after the end cover 4201 is connected to the driving mechanism, the main shaft 4101 rotates, without any biasing, thereby improving the rotation stability of the entire main brush shaft 4001 and improving the sweeping effect.
It should be mentioned that the above driving mechanism is generally driven by a motor, and other driving mechanisms for providing a driving force should also be regarded as the driving mechanism mentioned in the embodiments of the present disclosure.
Most of the garbage that travels to two ends of the main brush body 1001 will be sucked away and cleaned up, but there will be some that cannot be cleaned up in time. In order to prevent part of the garbage that has not been cleaned up punctually from falling back into the environment, an axial length of the sleeve 1301 is less than an axial length of the main brush body 1001, so that clearance grooves 1101 are constructed at two ends of the main brush body 1001. Referring to
Further, a gap 1401 is formed between the corresponding end cover 4201 and each of end surfaces of the two ends of the main brush body 1001. In order to avoid the situation that the garbage cannot enter the clearance grooves 1101 at the two ends of the main brush body 1001, referring to MG. 9, in a further improvement of the above embodiment, the gap 1401 is formed between the corresponding end cover 4201 and each of end surfaces of the two ends of the main brush body 1001. The gap 1401 between the end cover 4201 and the main brush body 1001 can provide a space for the garbage to be introduced. Specifically, in a case that the garbage on the blades 2001 travels to the two ends of the main brush body 1001 in an extension direction of the blades 2001, Part of the garbage that has not been sucked away will be introduced into the clearance grooves 1101 through the gap 1401 for storage under the action of a suction force, so as to facilitate the centralized treatment of this part of garbage after sweeping.
Specifically, the gap 1401 means that the end cover 3001 and the main brush body 1001 will not abut against each other after the end cover 3001 is assembled to the cleaning brush, but there is a distance between the end cover 3001 and the end of the main brush body 1001, and a space formed by this distance is the above-mentioned gap 1401.
It should be mentioned that the end covers 4201 are detachably installed at two ends of the main brush body 1001. The convenience of cleaning can be further improved. After cleaning, the end covers 4201 are disassembled directly, all the garbage in the clearance grooves 1101 can be poured out, and the end covers are then re-assembled.

The present disclosure further provides an intelligent cleaning device, which includes the cleaning brush proposed in the present disclosure and described in the above implementations.
From the above technical solutions, it can be seen that the cleaning brush and the intelligent cleaning device proposed in the present disclosure have the following advantages and positive effects.
The cleaning brush provided by the present disclosure includes the shaft rod, the cylindrical member and the end member. The end member is installed on the first end. The end member is provided with the blocking structure used for preventing an entanglement from excessively extending away from the cleaning brush. The end member and the first end are provided with installation structures matching each other respectively. The second end of the cylindrical member, which corresponds to the end member, covers at least a portion of the end member. With the above design, in the present disclosure, at least a portion of the end member intervenes between the shaft rod and the corresponding end of the cylindrical member, avoiding an entanglement wound on the cylindrical member from being wound to the shaft, rod directly. Instead, the entanglement is wound on the end member and can thus be removed with the disassembly of the end member, such that cleaning is more convenient.
The present disclosure further provides a cleaning brush. The cleaning brush includes a main brush body, a plurality of blades and a wool strip, wherein the main brush body is cylindrical and provided with a through hole inside. The plurality of blades are spirally fixed to the surface of the main brush body in an axial direction of the cleaning brush. One surface of the wool strip is provided with a plurality of bristles, and the other surface of the wool strip is fixedly connected to a part of the blades.
According to one implementation of the present disclosure, each blade has a sweeping surface for sweeping; and on a cross-section of the main brush body, one side of the blade away from the sweeping surface is inclined.
According to one implementation of the present disclosure, the sweeping surfaces of a part of the blades are provided with a plurality of salient points; and the sweeping surfaces of the remaining part of the blades are fixedly connected to the wool strip.
According to one implementation of the present disclosure, the bristles are perpendicular to the surface of the wool strip.
According to one implementation of the present disclosure, the blades include first blades and second blades, wherein the length of each first blade is less than the length of each second blade on the cross-section of the main brush body.
According to one implementation of the present disclosure, the wool strip is fixedly connected to the first blades merely.
According to one implementation of the present disclosure, the cleaning brush further includes a main brush shaft, the main brush shaft including a main shaft and end covers, wherein the end covers are detachably installed on two ends of the main shaft respectively; a through hole that axially penetrates the main brush body is formed inside the main brush body; and the main shaft is inserted into the through hole.
According to one implementation of the present disclosure, the main shaft is sleeved with a sleeve; the sleeve is sleeved with the main brush body; and an axial length of the sleeve is less than an axial direction of the main brush body, so as to form clearance grooves at two ends of the main brush body.
According to one implementation of the present disclosure, a gap is formed between the corresponding end cover and the end surface of each of two ends of the main brush body.
According to one implementation of the present disclosure, each end cover includes a barrel body and a connecting shaft, wherein the barrel body is provided with an installing groove in which the main shaft is inserted; the connecting shaft is inserted in the barrel body in an axial direction of the barrel body; one end of the connecting shaft extends out of the barrel body, and the other end of the connecting shaft is located in the installing groove; and an end of the main shaft is provided with an insertion groove in which the main shaft is inserted.
With the above design, the blades spirally distributed on the surface of the main brush body can guide slender-strip-shaped garbage such as hairs on the ground to swim to two ends of the main brush body while rotating and sweeping the ground, and at the same time cooperate with the wool strips on some of the blades. The plurality of bristles on the wool strip rub against the ground to generate static electricity, and shorter hairs are adsorbed on the bristles by means of the static electricity, such that hairs of all lengths on the ground can be effectively cleaned, thereby improving the sweeping quality.
