Detailed implementation manners

[0035] In the following description, a large number of specific details are given to provide a more thorough understanding of the technical solutions provided by the present utility model. However, it is obvious to those skilled in the art that the technical solutions provided by the present utility model can be implemented without one or more of these details.

[0036] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of the described features, wholes, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or combinations thereof.

[0037] Now, exemplary embodiments according to the present utility model will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many different forms and should not be construed as being limited only to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present utility model is thorough and complete, and the concept of these exemplary embodiments is fully conveyed to those of ordinary skill in the art.

[0038] As Figures 1 to 7 shown, an embodiment of the first aspect of the present utility model provides a side brush assembly 100, and an embodiment of the second aspect of the present utility model provides a cleaning device. Among them, the side brush assembly 100 is applied to the cleaning device. Among them, the cleaning device can be a sweeping robot, a mopping and sweeping integrated machine, or other cleaning robots that meet the requirements.

[0039] Specifically, the cleaning device includes but is not limited to: a main body, a cleaning system, a driving system, etc. The above-mentioned various systems cooperate with each other in a coordinated manner, enabling the cleaning device to move autonomously to achieve the cleaning function. The functional elements and the like that make up the above-mentioned various systems in the cleaning device are integrally arranged in the main body. It can be understood that the cleaning device can be a self-moving cleaning device, where the self-moving cleaning device is a device that automatically performs cleaning operations in a certain area to be cleaned without the operation of a user.

[0040] Among them, the main body includes a front part and a rear part, which can have an approximate circular shape or other shapes, including but not limited to an approximate D-shaped shape with a round rear and a rectangular or square shape with a front and a rear.

[0041] Among them, the cleaning system includes a dry cleaning system, that is, the cleaning device can be a sweeping robot, or the cleaning system includes a wet cleaning system and a dry cleaning system, that is, the cleaning device can be a mopping and sweeping integrated machine.

[0042] Among them, the dry cleaning system can include a roller brush, a dust box, and a suction fan. The roller brush that has a certain interference with the ground sweeps up the garbage on the ground and rolls it to the front of the suction port between the roller brush and the dust box, and then is sucked into the dust box by the suction gas generated by the suction fan and passing through the dust box.

[0043] Furthermore, for the cleaning device provided by the embodiment of the present utility model, the cleaning system may further include a side brush assembly 100. The side brush assembly 100 is rotatably connected to the main body and is used to move debris and other sundries outside the roller brush area into the roller brush area of the cleaning system.

[0044] At present, the side brush assembly in the related art is usually set in a three-claw structure, that is, the side brush assembly generally includes three brush arms and three bristles. The brush arms are symmetrically arranged on the circumferential side of the brush base. During the assembly process, one bristle will be exposed outside the main body. In this way, during the rotation of the side brush, the three bristles will rotate to the outside of the main body in sequence to increase the cleaning range and achieve the function of auxiliary cleaning. However, with this setting, even when the side brush assembly is not working, one bristle will still be exposed outside the main body, resulting in a relatively large overall volume of the cleaning device, which is not convenient for storage and movement.

[0045] In view of this, as Figure 1 , Figure 2 and Figure 3 shown, the side brush assembly 100 provided in the first aspect embodiment of the present invention includes: a brush base 110, a brush arm 120, and a bristle 130. The brush arms 120 are distributed on the circumferential side of the brush base 110, and the bristle 130 is connected to the end of the brush arm 120 away from the brush base 110. The brush base 110 is configured to be connected to the drive assembly of the cleaning device so that the drive assembly drives the brush base 110 to rotate; the included angles between at least two adjacent brush arms 120 are not equal.

[0046] Among them, the drive assembly can be installed on the main body of the cleaning device, and the brush base 110 is connected to the drive assembly, so that the drive assembly can drive the brush base 110 to rotate relative to the main body. Since the bristle 130 is connected to the brush base 110 through the brush arm 120, the rotation of the brush base 110 can drive the brush arm 120 and the bristle 130 to rotate synchronously, so that the bristle 130 can guide the debris and other sundries outside the roller brush area into the roller brush area of the cleaning system, realizing the role of auxiliary cleaning and improving the cleaning effect of the cleaning device.

[0047] In this embodiment, the angles between at least two adjacent brush arms 120 are not equal, that is, the brush arms 120 are arranged in an asymmetric structure in the circumferential direction of the brush base 110. It can be understood that the bristles 130 are arranged corresponding to the brush arms 120, and the number of the bristles 130 is the same as that of the brush arms 120, that is, the bristles 130 are arranged in an asymmetric structure in the circumferential direction of the brush base 110. With this arrangement, the bristles 130 can be more concentratedly distributed on a part of the circumferential side of the brush base 110, while the other part of the circumferential side of the brush base 110 is idle. For the same number of brush arms 120, compared with the symmetric structure of the brush arms 120 in the circumferential direction of the brush base 110, the idle part area on the circumferential side of the brush base 110 with the asymmetric structure of the brush arms 120 in the circumferential direction of the brush base 110 is larger. Therefore, during the assembly process of the side brush assembly 100 and the main body, the relative positions of the brush arms 120, the bristles 130 and the main body can be reasonably adjusted, so that the idle part on the circumferential side of the brush base 110 faces the outside of the edge of the adjacent part of the main body, so that the brush arms 120 and the bristles 130 are both located within the edge projection area of the main body, that is, the orthographic projection of the brush arms 120 and the bristles 130 on the horizontal plane is located within the area of the orthographic projection of the edge of the main body on the horizontal plane. Compared with the related art where some bristles of the side brush with a three-claw structure are exposed outside the main body with a symmetric structure on the circumferential side of the brush base, the space occupied by the cleaning device can be reduced, making the cleaning device easy to store, easy to avoid obstacles in shape, easy to be placed on and taken off the charging pile. At the same time, the appearance is more tidy, improving the market competitiveness.

[0048] Specifically, for the side brush with a three-claw structure in the related art, usually, the three brush arms are arranged in a symmetric structure on the circumferential side of the brush base, that is, the angle between the midlines of two adjacent brush arms is 120°. Therefore, when ignoring the width of the brush arms 120, the included angle of the space part on the circumferential side of the brush base 110 is about 120°. In this embodiment, the brush arms 120 are arranged in an asymmetric structure in the circumferential direction of the brush base 110. For example, the three brush arms 120 are arranged in an asymmetric structure in the circumferential direction of the brush base 110. When ignoring the width of the brush arms 120, the included angle of the space part on the circumferential side of the brush base 110 will be greater than 120°. Or, when the number of the brush arms 120 is greater than three or less than three, the position of the brush arms 120 in the circumferential direction of the brush base 110 can also be reasonably set so that the included angle of the space part on the circumferential side of the brush base 110 is greater than 120° when ignoring the width of the brush arms 120. In this way, during the assembly process of the side brush assembly 100 and the main body, the relative positions of the brush arms 120, the bristles 130 and the main body can be reasonably adjusted, so that the idle part on the circumferential side of the brush base 110 faces the outside of the edge of the adjacent part of the main body, so as to ensure that the brush arms 120 and the bristles 130 are both located within the edge projection area of the main body, and the bristles 130 will not be exposed outside the main body, reducing the space occupied by the cleaning device. It can be understood that when the brush base 110 rotates with the driving component, the bristles 130 will extend outside the edge projection area of the main body to increase the cleaning range and realize the function of auxiliary cleaning.

[0049] In some possible embodiments provided by the present utility model, the number of brush arms 120 is set to one or two. It can be understood that the number of bristles 130 is the same as that of the brush arms 120, that is, the number of bristles 130 is one or two. This setting makes the bristles 130 be more concentratedly distributed on a part of the circumferential side of the brush base 110 compared with the side brush of the three-claw structure in the related art, while the other part of the circumferential side of the brush base 110 is idle, and the idle part of the circumferential side of the brush base 110 has a larger area compared with the side brush of the three-claw structure. Therefore, during the assembly process of the side brush assembly 100 and the main body, the relative positions of the brush arms 120, the bristles 130 and the main body can be reasonably adjusted, so that the idle part of the circumferential side of the brush base 110 faces the outside of the edge of the adjacent part of the main body, so that the brush arms 120 and the bristles 130 are both located within the edge projection area of the main body, that is, the projections of the brush arms 120 and the bristles 130 on the horizontal plane are located within the area of the projection of the main body on the horizontal plane. Compared with the situation in the related art where some bristles of the side brush of the three-claw structure are exposed outside the main body, the space occupied by the cleaning device can be reduced, making the cleaning device easy to store, easy to avoid obstacles, easy to dock on the charging pile, and at the same time, making the appearance more tidy and improving the market competitiveness.

[0050] Specifically, for the side brush of the three-claw structure in the related art, usually, the three brush arms 120 are evenly distributed on the circumferential side of the brush base 110, that is, the included angle between the midlines of two adjacent brush arms is 120°. Therefore, when ignoring the width of the brush arms 120, the included angle of the space part on the circumferential side of the brush base 110 is about 120°. In this embodiment, when the number of brush arms 120 is one, when ignoring the width of the brush arms 120, the included angle of the idle part on the circumferential side of the brush base 110 is about 360°, which is obviously much larger than the included angle of the space part on the circumferential side of the brush base of the side brush of the three-claw structure. When the number of brush arms 120 is two, if the two brush arms 120 are arranged on the circumferential side of the brush base 110 with a maximum included angle of 180°, when ignoring the width of the brush arms 120, the included angle of the idle part on the circumferential side of the brush base 110 is about 180°, which is obviously also larger than the included angle of the space part on the circumferential side of the brush base 110 of the side brush of the three-claw structure. Therefore, due to the relatively large included angle of the space part on the circumferential side of the brush base 110 of the side brush assembly 100 in this embodiment, during the assembly process of the side brush assembly 100 and the main body, the relative positions of the brush arms 120, the bristles 130 and the main body can be reasonably adjusted, so that the idle part on the circumferential side of the brush base 110 faces the outside of the edge of the adjacent part of the main body to ensure that the brush arms 120 and the bristles 130 are both located within the edge projection area of the main body, and the bristles 130 will not be exposed outside the main body, reducing the space occupied by the cleaning device. It can be understood that when the brush base 110 rotates with the driving assembly, the bristles 130 will extend outside the edge projection area of the main body to increase the cleaning range and realize the function of auxiliary cleaning.

[0051] In some possible embodiments provided by the present utility model, the brush base 110 is provided with a first installation indicator 111, and the driving assembly is provided with a second installation indicator. The first installation indicator 111 and the second installation indicator are matched to indicate that the brush base 110 is in the installation position.

[0052] In this embodiment, by providing the first installation indicator 111 on the brush base 110 and the second installation indicator on the driving assembly, during the connection and assembly process of the side brush assembly 100 and the driving assembly, when the first installation indicator 111 and the second installation indicator are matched, it indicates that the brush base 110 is in the installation position, and the brush base 110 and the driving assembly can be connected in this posture to realize the connection and assembly of the side brush assembly 100 and the driving assembly.

[0053] Furthermore, when the brush base 110 is in the installation position, the bristles 130 are located within the edge projection area of the main body of the cleaning device, that is, the orthographic projection of the bristles 130 on the horizontal plane is located within the orthographic projection area of the edge of the main body of the cleaning device on the horizontal plane. That is to say, the bristles 130 do not extend outside the edge projection area of the main body. Therefore, compared with the related art in which some bristles are exposed outside the main body, the overall volume of the cleaning device when the brush base 110 is in the installation position is reduced, and further, the space occupied by the cleaning device when the brush base 110 is in the installation position is reduced, making the cleaning device easy to store, easy to avoid obstacles, easy to dock when the brush base 110 is in the installation position. At the same time, the appearance is relatively tidy, improving the market competitiveness.

[0054] When the brush holder 110 is in the installed position, the bristles 130 are located within the projection area of the edge of the cleaning device main body. It can be understood that the orthographic projection of the bristles 130 on the horizontal plane is located within the area of the orthographic projection of the edge of the main body on the horizontal plane. Among them, the brush holder 110 relative to the main body further includes a working position where some of the bristles 130 are located outside the main body. That is to say, when the brush holder 110 is in the working position, at least some of the bristles 130 are located within the projection area of the edge of the cleaning device main body. It can be understood that the orthographic projection of some of the bristles 130 on the horizontal plane is located outside the area of the orthographic projection of the edge of the main body on the horizontal plane; or, the orthographic projection of all the bristles 130 on the horizontal plane is located outside the area of the orthographic projection of the edge of the main body on the horizontal plane. In this example, the side brush assembly 100 relative to the main body can be set as a telescopic structure, so that when the brush holder 110 is in the installed position, the entire side brush assembly 100 can retract into the projection area of the edge of the main body, and when the brush holder 110 is in the working position, all the bristles 130 can extend outside the projection area of the edge of the main body. Specifically, when the brush holder 110 is in the working position, the cleaning device can use the side brush assembly 100 for auxiliary cleaning work. When the brush holder 110 is in the installed position, the cleaning device can not use the side brush assembly 100 for auxiliary cleaning work, and the cleaning device can be in the storage position, perform obstacle avoidance operations, docking operations, and perform auxiliary operations such as charging, dust collection, and water replenishment on the dock. Among them, the dock mentioned in this application can be understood as a charging pile, dust collection pile, base station, etc. used in conjunction with the cleaning device.

[0055] Furthermore, by providing a first installation indicator 111 on the brush holder 110, since the relative positions of the first installation indicator 111 and the brush arm 120 are known during the design process, and the relative positions of the bristles 130 and the brush arm 120 are also known during the design process, therefore, by matching the first installation indicator 111 with the second installation indicator on the drive assembly, the positions of the brush arm 120 and the bristles 130 relative to the main body can be restricted, so that when the brush holder 110 is in the installed position, the bristles 130 are located within the projection area of the edge of the main body.

[0056] Furthermore, the first installation indicator 111 and the second installation indicator cooperate to limit the rotation of the brush holder 110 relative to the main body, so that the brush holder 110 can be kept in the installed position relative to the main body when the drive assembly is not working. Specifically, the drive assembly can be a motor, the output shaft of the motor is connected to the brush holder 110, and the motor can be provided with a locking mechanism to ensure that the output shaft does not rotate when the motor is not working, so that after the output shaft and the brush holder 110 are matched by the first installation indicator 111 and the second installation indicator to make the brush holder 110 in the installed position, it can be kept in the installed position, avoiding the situation that the brush holder 110 rotates relative to the output shaft and the bristles 130 extend outside the projection area of the edge of the main body when the motor is not working.

[0057] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, in some possible embodiments provided by the present utility model, the brush base 110 is provided with a connection hole 112 for connecting with the driving component, and the first installation indicating member 111 is arranged on the hole wall of the connection hole 112. Therefore, when the brush base 110 is connected with the driving component through the connection hole 112, the first installation indicating member 111 on the hole wall of the connection hole 112 matches the second installation indicating member on the driving component, playing a role of limiting and anti-mistake, and can accurately and conveniently indicate that the brush base 110 is in the installation position.

[0058] Among them, one of the first installation indicating member 111 and the second installation indicating member is set as a concave part, and the other is set as a convex part. The concave part and the convex part are convenient for processing and easy to implement, which is beneficial to reducing the overall processing cost of the side brush assembly 100. At the same time, the concave part and the convex part have a good limiting and anti-mistake effect and are convenient for assembly, and can accurately, conveniently and quickly indicate that the brush base 110 is in the installation position, and is suitable for popularization and application.

[0059] Specifically, the first installation indicating member 111 can be a convex part, and the second installation indicating member can be a concave part, or the first installation indicating member 111 can be a concave part, and the second installation indicating member can be a convex part. It can be understood that in some examples, the first installation indicating member 111 can include a concave part and a convex part, and the second installation indicating member can also include corresponding convex and concave parts, so as to meet the requirements of different structures of the first installation indicating member 111 and the second installation indicating member.

[0060] Furthermore, the driving component includes a motor, and the output shaft of the motor is connected with the brush base 110 through the connection hole 112, that is, the second installation indicating member can be arranged on the output shaft. Specifically, the first installation indicating member 111 can be a convex structure 122, and the second installation indicating member can be a groove structure.

[0061] As Figure 3 and Figure 4 shown, in some possible embodiments provided by the present utility model, the side brush assembly 100 further includes: a connecting piece. The connection hole 112 includes a first hole section 1121 and a second hole section 1122 along the axial direction of the brush base 110. The first hole section 1121 is located above the second hole section 1122 and matches the driving component. The first installation indicating member 111 is arranged on the first hole section 1121, and the connecting piece passes through the second hole section 1122 to be connected with the driving component. Among them, the axial direction of the brush base 110 can be as shown by the arrow Z in Figure 4 .

[0062] Thus, during the assembly process of the side brush assembly 100 and the drive assembly, first, the first hole section 1121 is used to match with the drive assembly for preliminary pre-positioning. Then, the first installation indicator 111 of the first hole section 1121 is used to match with the second installation indicator on the drive assembly to achieve the function of limit and anti-mistake, accurately position the assembly of the brush holder 110 and the drive assembly, so that the brush holder 110 can be accurately and quickly in the installation position, ensuring that the bristles 130 are located within the edge projection area of the main body. Then, a connecting piece is passed through the second hole section 1122 to connect with the drive assembly, and the reliable connection between the brush holder 110 and the drive assembly can be achieved. The operation is simple and is beneficial to improving the assembly efficiency and assembly accuracy of the brush holder 110 and the drive assembly.

[0063] Specifically, the first hole section 1121 can be polygonal, and the output shaft of the drive assembly can be polygonal. Thus, by using the cooperation of the polygonal hole and the polygonal shaft, it has a good limiting effect and can limit the rotation of the brush holder 110 relative to the output shaft, ensuring that the brush holder 110 and the output shaft can rotate synchronously. Specifically, the first hole section 1121 can be hexagonal, and the output shaft of the drive assembly can also be hexagonal. It can be understood that the first hole section 1121 can also be of other shapes.

[0064] Among them, the opening size of the first hole section 1121 can be larger than the opening size of the second hole section 1122. For example, the connecting piece can be a bolt, the second hole section 1122 can be circular, the opening size of the first hole section 1121 can be understood as the radial dimension of the second hole section 1122, and a threaded hole is provided at the end of the output shaft of the drive assembly. The bolt passes through the second hole section 1122 and connects with the threaded hole, and the output shaft and the brush holder 110 can be connected.

[0065] Such as Figure 4 As shown, in some possible implementation embodiments provided by the present utility model, the connecting hole 112 further includes a third hole section 1123 located below the second hole section 1122, and the end of the connecting piece away from the drive assembly is accommodated in the third hole section 1123.

[0066] In this embodiment, the setting of the third hole section 1123 provides a accommodating space for the end of the connecting piece away from the drive assembly, so that the connecting piece will not protrude from the bottom of the brush holder 110. Thus, it can reduce or avoid the problem that the connecting piece protrudes from the bottom of the brush holder 110 and makes it easy for sundries such as hair and threads to wind around the connecting piece, resulting in difficult disassembly and jamming of the connecting piece. Furthermore, it reduces the interference of sundries such as hair and threads on the connecting piece, enables the connecting piece to be disassembled quickly and conveniently, improves the disassembly efficiency and maintenance efficiency of the side brush assembly 100, and at the same time ensures that the side brush assembly 100 can work reliably.

[0067] Specifically, the opening size of the third hole section 1123 can be larger than that of the second hole section 1122. The second hole section 1122 can be circular, and the opening size of the third hole section 1123 can be understood as the radial dimension of the second hole section 1122. The connecting piece can be a bolt, and the head of the bolt is received in the third hole section 1123, so that the bolt does not protrude from the bottom of the brush holder 110, reducing or avoiding the phenomenon that the head of the bolt is wound by hair.

[0068] As Figure 1 , Figure 2 and Figure 5 shown, in some possible embodiments provided by the present utility model, the number of brush arms 120 is two, the brush arms 120 are spiral, and the bristles 130 correspond to the brush arms 120, that is, the number of bristles 130 is two and are connected to the corresponding brush arms 120. Among them, the bristles 130 extend along the tangent direction of the brush arms 120, and the included angle between the extending directions of the two bristles 130 is not greater than 120°.

[0069] Among them, the two brush arms 120 and the two bristles 130 can ensure that the side brush assembly 100 has a larger cleaning range, which is beneficial to ensuring a good cleaning effect.

[0070] Among them, the included angle between the extending directions of the two bristles 130 can be as shown by the angle α in Figure 5 , that is, α is less than or equal to 120°. Thus, the two brush arms 120 and the two bristles 130 can be more concentratedly distributed on a part of the circumferential side of the brush holder 110, while the other part of the circumferential side of the brush holder 110 is idle and no brush arms 120 and bristles 130 are provided. In this way, by reasonably setting the installation position of the brush holder 110, when the brush holder 110 is in the installation position, the brush arms 120 and the bristles 130 are arranged close to the inside of the main body, and the idle part of the circumferential side of the brush holder 110 faces the outside of the main body to ensure that the two bristles 130 are located inside the edge projection of the main body. And the brush holder 110 can be arranged at a position close to the edge at the bottom of the main body to ensure that when the brush holder 110 is in the installation position, the bristles 130 are located within the edge projection area of the main body, and when the brush holder 110 is in the working position, the bristles 130 can smoothly extend to the outside of the main body, ensuring a larger cleaning range and facilitating the switching of the brush holder 110 between the installation position and the working position.

[0071] Furthermore, since the side brush assembly in the related art is usually installed at a position near the edge of the bottom of the main body, for example, if there are three brush arms, usually one brush hair extends outside the edge projection area of the main body, making the overall volume of the cleaning device relatively large, inconvenient for storage and movement, and the appearance is not tidy. In this embodiment, by setting the side brush assembly 100 to have two brush arms 120, and the brush hairs 130 extend along the tangent direction of the brush arms 120, and the included angle between the extension directions of the two brush hairs 130 is not greater than 120°. Thus, without changing the original structure of the cleaning device, the side brush assembly 100 in this embodiment is adapted to the second installation indicator of the driving component through the first installation indicator 111, and when the brush base 110 is in the installation position, it can be ensured that the brush hairs 130 are located within the edge projection area of the main body, reducing the overall volume of the cleaning device, and further reducing the space occupied by the cleaning device, making the cleaning device convenient for storage, obstacle avoidance movement, and docking when the brush base 110 is in the installation position. At the same time, the appearance of the cleaning device has a high degree of neatness, improving the market competitiveness.

[0072] Specifically, the included angle α between the extension directions of the two brush hairs 130 can be 120°, 110°, 100°, 90°, 80°, or other angles. By reasonably setting the angle of the included angle α between the extension directions of the two brush hairs 130, when the brush base 110 is in the installation position, the two brush hairs 130 can be more comprehensively located within the edge projection area of the main body. At the same time, it is ensured that the two brush hairs 130 have a large radiation range to ensure a good auxiliary cleaning effect when the brush base 110 is in the working position.

[0073] Such as Figure 1 、 Figure 5 and Figure 6 As shown, in some possible embodiments provided by the present utility model, the projection of the brush arm 120 on the horizontal plane is an involute. Among them, the involute refers to the locus of a point K on a straight line when the straight line rolls purely on a circle. In this embodiment, the brush arm 120 is spiral, and the projection of the spiral brush arm 120 on the horizontal plane is an involute. It can be understood that the brush base 110 is cylindrical, the axis of the brush base 110 can be regarded as perpendicular to the horizontal plane, the brush arm 120 is spirally distributed in the axial direction of the brush base 110, and the projection of the brush arm 120 on the horizontal plane coincides with the part of the locus of the point K on the straight line when the straight line rolls purely on the cylindrical brush base 110 and is connected to the brush base 110. Among them, pure rolling means that the contact point between the rigid body and the plane is relatively stationary at the moment of contact, without any relative sliding, that is, rolling with a relative speed of zero. When the plane is a fixed plane, the contact point is the instantaneous center of velocity of the two objects.

[0074] Among them, the horizontal plane can be regarded as perpendicular to the rotation axis of the brush holder 110. Since the brush arm 120 is spiral, the projection of the brush arm 120 on the horizontal plane is a section of involute helix. In this way, during the rotation of the brush holder 110, sundries such as hair and threads wound around the brush arm 120 will move along the rotating and spiral brush arm 120 and will be tightly wound around the brush arm 120. During the continuous rotation of the brush holder 110, the force of the sundries winding around the brush arm 120 will increase. The brush arm 120 is set as an elastic member. When the winding force of the sundries on the brush arm 120 reaches the limit value that the elastic brush arm 120 can bear, the brush arm 120 will elastically deform and bounce off the sundries wound around the brush arm 120, reducing the possibility of winding of sundries such as hair and threads. Furthermore, it can reduce the frequency of the user cleaning the side brush assembly 100, extend the replacement cycle of the side brush assembly 100, reduce the use cost, and improve the user experience.

[0075] As Figure 5 shown, in some possible embodiments provided by the present utility model, the two brush arms 120 are located on the same side of the midline of the brush holder 110 passing through the rotation axis of the brush holder 110. This setting can ensure that the two brush arms 120 are relatively concentrated on the circumferential side of the brush holder 110, and there is a large range on the circumferential side of the brush holder 110 where no brush arm 120 is provided, so as to ensure that the original structure of the cleaning device is not changed. When the side brush assembly 100 is connected to the driving assembly and the brush holder 110 is in the installation position, the two brush hairs 130 can effectively be located within the edge projection area of the main body, and when the brush holder 110 is in the working position, part of the brush hairs 130 can be located outside the edge projection area of the main body.

[0076] As Figure 5 shown, in some possible embodiments provided by the present utility model, the included angle between the extending direction of the brush hair 130 and the extending direction of the connected brush arm 120 relative to the brush holder 110 is not greater than 120°, that is, the included angle between the extending direction of the brush hair 130 and the extending direction of the connected brush arm 120 relative to the brush holder 110 is less than or equal to 120°. Among them, the included angle between the extending direction of the brush hair 130 and the extending direction of the connected brush arm 120 relative to the brush holder 110 can be as Figure 5 shown by the angle β in, that is, β is less than or equal to 120°. Specifically, β can be 120°, 110°, 100°, 90°, 80°, or other angles.

[0077] This kind of setting can ensure that the two brush arms 120 and the two brush hairs 130 are relatively concentratedly arranged on a partial circumferential side of the brush base 110, while there is no brush arm 120 arranged on the other partial circumferential side of the brush base 110. When the brush base 110 rotates relative to the main body to different positions, the two brush hairs 130 can effectively be located within the edge projection area of the main body so that the brush base 110 is in the installation position, or part of the brush hairs 130 can be located outside the edge projection area of the main body so that the brush base 110 is in the working position. Thus, on the basis of not changing the original structure of the cleaning device, the side brush assembly 100 provided in this embodiment can be connected to the driving assembly. By reasonably defining the installation position of the brush base 110 through the first installation indicator 111 and the second installation indicator, it can be ensured that the brush hairs 130 are located within the edge projection area of the main body when the brush base 110 is in the installation position, and by driving the brush base 110 to rotate through the driving assembly, the switching between the installation position and the working position of the brush base 110 can be realized. The operation is simple and easy to implement.

[0078] As Figure 6 and Figure 7 shown, in some possible implementation embodiments provided by the present utility model, the brush arm 120 includes a first end 121 connected to the brush hair 130. A convex structure 122 is arranged at the bottom of the first end 121, and the brush hair 130 is arranged obliquely downward relative to the convex structure 122 by the first end 121. Thus, the brush hair 130 has sufficient interference force on the surface to be cleaned to ensure a good cleaning effect. At the same time, this kind of setting makes the convex structure 122 located below the part where the brush hair 130 is connected to the first end 121 to prevent sundries from moving or creeping along the brush arm 120 from the lower part of the first end 121 towards the direction close to the brush base 110. That is to say, the setting of the convex structure 122 can limit the movement of sundries such as hair and thread along the brush arm 120 from the first end 121 towards the direction close to the brush base 110, and further can reduce the approach of sundries such as hair and thread to the brush base 110, reducing the possibility that sundries enter the driving assembly through the brush arm 120 and the brush base 110 to cause a failure of the driving assembly, and further being beneficial to extending the service life of the driving assembly and improving the reliability of the driving assembly.

[0079] Specifically, the driving assembly can be a motor, and the brush base 110 is connected to the output shaft of the motor. When the side brush assembly 100 is wound with sundries such as hair and thread, if the sundries such as hair and thread wind upward along the circumferential side wall of the brush base 110 and wind on the output shaft, there will be a phenomenon of the output shaft being stuck, which will affect the reliability of the motor. Through the setting of the convex structure 122 in this application, the occurrence of this kind of situation can be greatly reduced, and further the service life of the motor can be extended.

[0080] As Figure 6 and Figure 7As shown, in some possible embodiments provided by the present utility model, the first end portion 121 includes a first part 1211 and a second part 1212 located above the first part 1211. The first part 1211 is provided with a convex structure 122 and is connected to the bristles 130. The second part 1212 protrudes from the first part 1211 along the extending direction of the brush arm 120. Among them, the up and down direction is as Figure 7 shown by the arrow Z in

[0081] That is to say, the second part 1212 is located above the bristles 130, and the convex structure 122 is located below the bristles 130. Thus, the second part 1212 forms a structure similar to a retaining rib, which can prevent debris from moving along the bristles 130 towards the brush arm 120 from above the bristles 130. Therefore, through the cooperation of the second part 1212 and the convex structure 122, debris moving along the bristles 130 towards the brush arm 120 can be blocked at the first end portion 121 from both above and below the bristles 130, thereby further restricting the possibility of debris such as hair and threads moving along the bristles 130 through the first end portion 121 to the brush arm 120, that is, reducing the possibility of the brush arm 120 being entangled by debris such as hair and threads. Furthermore, it can reduce the approach of debris such as hair and threads to the brush base 110, and reduce the possibility of debris entering the drive assembly through the brush arm 120 and the brush base 110, resulting in drive assembly failure. Therefore, it is beneficial to extend the service life of the drive assembly and improve the reliability of the drive assembly.

[0082] As Figure 6 and Figure 7 shown, in some possible embodiments provided by the present utility model, the second part 1212 is inclined upward relative to the first part 1211 in a direction away from the brush base 110. That is to say, the gap between the second part 1212 and the bristles 130 gradually increases from the direction away from the brush base 110 to the direction close to the brush base 110. This kind of setting plays a guiding role in the movement of debris along the bristles 130, enabling debris to be smoothly accommodated in the gap between the second part 1212 and the bristles 130 along the bristles 130, reducing the possibility of debris moving from above the second part 1212 to the brush arm 120, and playing a good role in preventing the brush arm 120 from being entangled by debris such as hair and threads.

[0083] As Figure 4 shown, in some possible embodiments provided by the present utility model, the brush arm 120 includes a second end portion 123 connected to the brush base 110, and the brush base 110 is injection-molded and wrapped around the outside of the second end portion 123. That is to say, the brush base 110 and the brush arm 120 can be processed by an injection molding and insert molding process. Thus, it can ensure the reliability of the connection between the brush arm 120 and the brush base 110. At the same time, it is convenient for processing and easy to produce.

[0084] Furthermore, both the brush arm 120 and the brush base 110 are plastic parts, which have low costs and are easy to form,

[0085] convenient for processing and suitable for popularization and application.

[0086] Among them, the hardness of the brush base 110 is greater than that of the brush arm 120. For example, the brush base 110 is made of hard rubber and the brush arm 120 is made of soft rubber. Thus, it can ensure that the brush base 110 has sufficient hardness and strength, and the brush arm 120 has sufficient strength and elasticity. Specifically, the elasticity of the brush arm 120 is greater than that of the brush base 110.

[0087] Such as Figure 5 shown, in some possible embodiments provided by the present utility model, the brush arm 120 includes a first section 124, a second section 125, and a third section 126 arranged in sequence along the direction from the brush base 110 to the brush bristles 130. Among them, the first section 124, the second section 125, and the third section 126 gradually become thinner.

[0088] Among them, the first section 124, the second section 125, and the third section 126 gradually become thinner, which can be understood as the width of the projections of the first section 124, the second section 125, and the third section 126 in the horizontal plane gradually becoming smaller, or it can be understood as the size of the first section 124, the second section 125, and the third section 126 in the vertical direction gradually becoming smaller, or it can be understood as the width of the projections of the first section 124, the second section 125, and the third section 126 in the horizontal plane gradually becoming smaller, and at the same time, the size of the first section 124, the second section 125, and the third section 126 in the vertical direction gradually becoming smaller. Specifically, the width of the projection of the brush arm 120 in the horizontal plane can be as Figure 5 shown by the distance D in the figure, and the size of the brush arm 120 in the vertical direction can be the size of the brush arm 120 along the Z-axis direction.

[0089] This kind of setting can ensure that the first section 124 connected to the brush base 110 has sufficient strength, so that the brush base 110 and the brush arm 120 can be reliably connected. At the same time, it can ensure that the third section 126 connected to the brush bristles 130 has sufficient elasticity, and further enables the brush bristles 130 to have sufficient pressing force on the surface to be cleaned to ensure a good cleaning effect. And the second section 125 located between the first section 124 and the third section 126 can realize the transitional connection between the first section 124 and the third section 126, so that from the first section 124 to the third section 126, the strength of the brush arm 120 gradually decreases and the elasticity of the brush arm 120 gradually increases to ensure that the brush arm 120 has good strength and elasticity. It can be understood that when the brush base 110 rotates and works, the starting point of the deformation position of the brush arm 120 can be located at the second section 125 of the brush arm 120.

[0090] An embodiment of the second aspect of the present utility model provides a cleaning device, including: a main body, and the side brush assembly 100 of any one of the embodiments in the first aspect. The side brush assembly 100 is located at the bottom of the main body. Since the cleaning device includes the side brush assembly 100 of any one of the foregoing embodiments, it has all the technical effects of the foregoing side brush assembly 100, which will not be elaborated herein one by one.

[0091] Further, the cleaning device further includes: a driving component, which is connected to the brush holder 110 to drive the brush holder 110 to rotate.

[0092] In one example, the driving component is configured to drive the brush holder 110 to switch between the installation position and the working position, so as to realize the auxiliary cleaning function of the side brush assembly 100. That is to say, when the driving component drives the brush holder 110 to rotate, the switching between the installation position and the working position of the brush holder 110 can be realized. Specifically, when the brush holder 110 is in the working position, part of the bristles 130 extends outside the edge projection area of the main body.

[0093] In another example, the cleaning device further includes a telescopic component, which is connected to the brush holder 110 to drive the brush holder 110 to switch between the installation position and the working position. When in the installation position, the bristles 130 are located within the projection edge area of the main body, and when in the working position, part of the bristles 130 are located outside the projection edge area of the main body. That is to say, the telescopic component drives the brush holder 110 to telescope relative to the main body to realize the switching between the installation position and the working position of the brush holder 110. It can be understood that in this case, the driving component is used to drive the brush holder 110 to rotate. For example, the driving component can drive the brush holder 110 to rotate when the brush holder 110 is in the working position, or the driving component can also drive the brush holder 110 to rotate when the brush holder 110 is in the installation position.

[0094] The present utility model has been described through the above embodiments. However, it should be understood that the above embodiments are only for the purpose of illustration and example, and are not intended to limit the present utility model to the scope of the described embodiments. In addition, those skilled in the art can understand that the present utility model is not limited to the above embodiments, and more variations and modifications can be made according to the teachings of the present utility model, and these variations and modifications all fall within the scope of protection required by the present utility model. The scope of protection of the present utility model is defined by the appended claims and their equivalent scope.
