DETAILED DESCRIPTION

[0027] In the following description, a large number of specific details are given to provide a more thorough understanding of the technical solution provided by the utility model. However, it is obvious to those skilled in the art that the technical solution provided by the utility model can be implemented without one or more of these details.

[0028] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the 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, it indicates the presence of the features, wholes, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or combinations thereof.

[0029] 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 a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present utility model thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0030] like Figures 1 to 5 As shown, an embodiment of the first aspect of the utility model provides a side brush assembly 200, and an embodiment of the second aspect of the utility model provides a cleaning device 100, wherein the side brush assembly 200 is applied to the cleaning device 100, wherein the cleaning device 100 can be a sweeping robot, a sweeping and mopping machine, or other cleaning robots that meet the requirements.

[0031] Specifically, the cleaning device 100 includes, but is not limited to, a main body 110, a cleaning system 130, a drive system 120, etc. The above-mentioned systems cooperate with each other so that the cleaning device 100 can move autonomously to achieve the cleaning function. The functional elements constituting the above-mentioned systems in the cleaning device 100 are integratedly arranged in the main body 110. It is understandable that the cleaning device 100 can be a self-moving cleaning device. A self-moving cleaning device is a device that automatically performs a cleaning operation in a certain area to be cleaned without user operation.

[0032] As shown in FIG. 1 , the main body 110 includes a forward portion 111 and a rearward portion 112 , and has an approximately circular shape or other shapes, including but not limited to an approximately D-shaped shape with a front and rear circle, and a rectangular or square shape with a front and rear circle.

[0033] like Figure 2 As shown, the drive system 120 can manipulate the main body 110 to travel across the ground based on a drive command with distance and angle information such as x, y and θ components. The drive system 120 includes a drive wheel module 121, and the drive wheel module 121 can control the left wheel and the right wheel at the same time. In order to more accurately control the movement of the machine, it is preferred that the drive wheel module 121 includes a left drive wheel module and a right drive wheel module respectively. The left and right drive wheel modules are arranged along the transverse axis defined by the main body 110. In order for the cleaning device 100 to be able to move more stably or more powerfully on the ground, the cleaning device 100 may include one or more driven wheels 122, and the driven wheels 122 include but are not limited to universal wheels. The drive wheel module 121 includes a walking wheel and a drive motor and a control circuit for controlling the drive motor. The drive wheel module 121 can also be connected to a circuit and an odometer for measuring the drive current.

[0034] like Figure 2 As shown, the cleaning system 130 includes a dry cleaning system 131, that is, the cleaning device 100 can be a sweeping robot, or the cleaning system 130 includes a wet cleaning system 132 and a dry cleaning system 131, that is, the cleaning device 100 can be a sweeping and mopping machine.

[0035] like Figure 2 As shown, the dry cleaning system 131 provided in the embodiment of the utility model may include a roller brush, a dust box, and a dust suction fan. The roller brush with a certain interference with the ground sweeps up the garbage on the ground and rolls it to the front of the dust suction port between the roller brush and the dust box, and then the suction gas generated by the dust suction fan and passing through the dust box is sucked into the dust box.

[0036] Furthermore, if Figure 2As shown, the cleaning device 100 provided by the embodiment of the utility model, the cleaning system 130 may also include a side brush assembly 200, which is rotatably connected to the machine body 110 and is used to move debris and other sundries outside the roller brush area into the roller brush area of ​​the cleaning system 130.

[0037] like Figure 3 , Figure 4 and Figure 5 As shown, the side brush assembly 200 provided by the utility model includes: a side brush body 210 and a connecting piece, the side brush body 210 includes a base 211, and at least one support leg 212 distributed on the side of the base 211, the base 211 is connected to the driving assembly of the cleaning device 100 through the connecting piece, the driving assembly is used to drive the side brush body 210 to rotate, the support leg 212 is spiral, and the projection of the support leg 212 on the horizontal plane is a section of involute.

[0038] Among them, the involute refers to the trajectory of a point K on a straight line when the straight line rolls purely on a circle, which is called the involute of the circle. The side brush assembly 200 provided by the embodiment of the utility model has a spiral support foot 212, and the projection of the spiral support foot 212 on the horizontal plane is a segment of involute. It can be understood that the base 211 is cylindrical, the axial direction of the base 211 can be regarded as perpendicular to the horizontal plane, the support foot 212 is distributed in a spiral shape on the axial direction of the base 211, and the projection of the support foot 212 on the horizontal plane coincides with the part of the trajectory of the point K on the straight line when the straight line rolls purely on the cylindrical base 211 that is connected to the base 211.

[0039] In this embodiment, the driving component can be installed on the machine body 110 of the cleaning device 100, and the base 211 is connected to the driving component through a connecting piece, so that the driving component can drive the base 211 to rotate relative to the machine body 110, and then drive the support legs 212 connected to the peripheral side of the base 211 to move synchronously, so that the support legs 212 can guide debris and other sundries outside the roller brush area into the roller brush area of ​​the cleaning system 150, thereby achieving the function of auxiliary cleaning and improving the cleaning effect of the cleaning device 100.

[0040] Among them, the horizontal plane can be regarded as perpendicular to the rotation axis of the side brush body 210. Since the support foot 212 is spiral, the projection of the support foot on the horizontal plane is a spiral involute. In this way, during the rotation of the side brush body 210, hair, wires and other debris wrapped around the support foot 212 will move along the rotating, spiral support foot 212 and will be tightly wrapped around the support foot 212. During the continued rotation of the side brush body 210, the force of the debris wrapping around the support foot 212 will increase. The support foot 212 is set as an elastic member. When the wrapping force of the debris on the support foot 212 reaches the limit value that the elastic support foot 212 can withstand, the elastic deformation of the support foot 212 will bounce off the debris wrapped around the support foot 212, reducing the possibility of entanglement of hair, wires and other debris, thereby reducing the frequency of users cleaning the side brush assembly 200, and extending the replacement cycle of the side brush assembly 200, reducing the use cost, and improving the user experience.

[0041] Furthermore, the number of the legs 212 is at least one, such as the number of the legs 212 can be one, two, three, four, or other numbers. The number of the legs 212 can be reasonably set according to the size of the legs 212 and the size of the base 211. It is understood that the spiral directions of at least two legs 212 are the same. Specifically, Figure 3 , Figure 4 and Figure 5 As shown, the number of legs 212 is three.

[0042] In some possible embodiments provided by the present invention, the rotation direction of the side brush body 210 is configured to be opposite to the spiral direction of the support foot 212 .

[0043] This arrangement enables the side brush assembly 200 to effectively guide debris and other sundries outside the roller brush area into the roller brush area of ​​the cleaning system 150, thereby improving the cleaning effect.

[0044] At the same time, since the projection of the spiral foot 212 on the horizontal plane is a spiral involute, and the rotation direction of the side brush body 210 is configured to be opposite to the spiral direction of the foot 212, that is, during the rotation of the side brush body 210, the direction of the inertial force of the debris on the foot 212 is substantially opposite to the direction of the spiral involute of the foot 212. In this way, the hair, wire and other debris entangled on the foot 212 will move along the direction of the spiral involute extending from the foot 212 toward the direction of the rotation axis of the base 211 to be entangled on the foot 212 due to the action of the inertial force during the rotation of the side brush body 210. As the side brush body 210 continues to rotate, the force of debris entangled with the support foot 212 will increase. This can shorten the time it takes for the entanglement force of the debris on the support foot 212 to reach the limit value that the elastic support foot 212 can withstand, so that the entanglement force of the debris on the support foot 212 can quickly reach the limit value that the elastic support foot 212 can withstand. As a result, the elastic deformation of the support foot 212 will bounce off the hair, thread and other debris entangled on the support foot 212, reducing the possibility of entanglement of hair, thread and other debris, thereby reducing the frequency of users cleaning the side brush assembly 200, and extending the replacement cycle of the side brush assembly 200, reducing the cost of use, and improving the user experience.

[0045] Specifically, in the side brush assembly in the related art, the legs are usually distributed on the peripheral side of the base in a straight line, and the bristles are connected to the ends of the legs. In the side brush assembly of this structure, hair, wires and other debris are easily entangled, which makes the front end of the bristles easily deformed, affecting the cleaning effect. Therefore, under normal circumstances, the side brush assembly needs to be replaced as a whole every 3 to 6 months. In the side brush assembly 200 provided by the embodiment of the utility model, the spiral legs 212 are distributed on the peripheral side of the base 211 in an involute manner, and the rotation direction of the side brush body 210 is opposite to the spiral direction of the legs 212. As a result, the hair, wires and other debris entangled on the legs 212 can be bounced off, reducing the possibility of entanglement of hair, wires and other debris, extending the cleaning cycle and service life of the side brush assembly 200, greatly reducing the cost of use, and improving the user experience.

[0046] In some possible embodiments provided by the present invention, the side brush assembly 200 further includes bristles 220, which are connected to the support leg 212 and are located at one end of the support leg 212 away from the base 211. Thus, the driving assembly can drive the base 211 to rotate relative to the machine body 110, and since the bristles 220 are connected to the support leg 212 on the side of the base 211, the bristles 220 can rotate synchronously with the base 211 to guide debris and other debris outside the roller brush area into the roller brush area of ​​the cleaning system 150, thereby achieving the function of auxiliary cleaning and improving the cleaning effect of the cleaning device 100.

[0047] Among them, the bristles 220 are located below the base 211. In this way, when the bristles 220 interfere with the surface to be cleaned and are deformed, the base 211 will be located above the surface to be cleaned and will not interfere with the surface to be cleaned, thereby ensuring that the side brush body 210 can rotate reliably under the drive of the driving component to ensure a good cleaning effect.

[0048] That is, the side brush assembly 200 provided by the embodiment of the utility model can simplify the arrangement of the bristles 220, and use the support feet 212 on the side brush body 210 to achieve the auxiliary cleaning function, thereby reducing the manufacturing cost. Alternatively, the side brush assembly 200 can include bristles 220 to ensure a good cleaning effect. At the same time, compared with the support feet 212, the bristles 220 make less noise when contacting the surface to be cleaned, which is conducive to improving the comfort of the user.

[0049] like Figure 3 , Figure 4 and Figure 5 As shown, in some possible embodiments provided by the present invention, the top of the base 211 is configured as a connection side 2111 connected to the drive assembly, that is, the drive assembly is located above the base 211, that is, the entire side brush assembly 200 is located at the bottom of the machine body 110 to interfere with the surface to be cleaned.

[0050] The circumferential side of the base 211 is provided with a limiting boss 213, which is located below the top of the base 211, that is, the limiting boss 213 is located below the connection side 2111, so as to prevent debris from moving or swaying from the bottom of the base 211 to the direction close to the connection side 2111. The setting of the limiting boss 213 can limit the upward winding of debris such as hair and thread along the circumferential side wall of the base 211, reduce the possibility of debris entering the drive assembly through the connection side 2111 of the base 211 and causing the drive assembly to malfunction, thereby helping to extend the service life of the drive assembly and improve the reliability of the drive assembly.

[0051] Specifically, the driving assembly can be a motor, and the base 211 is connected to the output shaft of the motor, so that the motor rotates, and the base 211 is driven to rotate synchronously through the output shaft, thereby driving the entire side brush assembly 200 to rotate. When the side brush assembly 200 is entangled with hair, thread, and other debris, if the hair, thread, and other debris are wound upward along the circumferential side wall of the base 211, and are wound around the output shaft through the connecting side 2111, the output shaft may be stuck, thereby affecting the reliability of the motor. The utility model can greatly reduce the occurrence of such a situation by setting the limiting boss 213, thereby extending the service life of the motor.

[0052] Furthermore, at least the support leg 212 is configured as an elastic member. By configuring the support leg 212 as an elastic member, hair, thread and other debris wrapped around the support leg 212 will cause the support leg 212 to be deformed by force. For example, the support leg 212 will shrink along the spiral line under the action of the hair and thread debris, and the limiting boss 213 located on the side of the base 211 will limit the hair and thread debris from continuing to wrap upward, preventing the debris from entering the drive assembly and damaging the drive assembly, thereby increasing the service life of the drive assembly. When the force of the hair, thread and other debris wrapped around the support leg 212 reaches the limit value of the support leg 212, the support leg 212 will directly bounce the hair, thread and other debris away due to deformation, thereby achieving the anti-winding effect, and the bounced debris will fall into the roller brush cleaning area under the action of the side brush assembly 200 to be recovered into the dust box.

[0053] Furthermore, the support leg 212 and the base 211 can be an integrally formed structure, that is, the base 211 can also be an elastic member. The integrally formed support leg 212 and the base 211 is easy to process, conducive to mass production, and conducive to reducing manufacturing costs. It is understandable that in other examples, the support leg 212 and the base 211 can also be made of different materials.

[0054] like Figure 3 , Figure 4 and Figure 5 As shown, in some possible embodiments provided by the present invention, the limiting boss 213 corresponds to the support leg 212, and the projection of the limiting boss 213 on the horizontal plane is close to the connection position between the support leg 212 and the base 211. For example, the support leg 212 includes a first end 2121 and a second end 2122, the first end 2121 is connected to the base 211, and the second end 2122 is connected to the bristles 220; the projection of the limiting boss 213 on the horizontal plane is located on the side of the first end 2121 close to the second end 2122.

[0055] That is, a limiting boss 213 is disposed near the first end 2121 of each support leg 212, and the limiting boss 213 is located on the side of the first end 2121 close to the second end 2122. When the driving assembly drives the side brush body 210 to rotate, most of the debris (such as debris, hair, thread, etc.) will extend in the direction of the support leg 212 away from the base 211 under the guidance of the support leg 212, or the bristles 220 and the support leg 212, so as to move the debris and other debris to the rolling brush area of ​​the cleaning system 150, and a small amount of debris (such as hair, thread, etc.) will move along the support leg 212 from the second end 2122 to the first end 2121 with a movement tendency close to the connection side 2111. Therefore, the utility model sets a limiting boss 213 near the first end 2121 of each supporting leg 212, and uses the limiting boss 213 to limit the continued upward movement of debris that moves from the second end 2122 of the supporting leg 212 to the vicinity of the first end 2121, so that the debris can be reliably confined below the limiting boss 213, avoiding the possibility of debris entering the drive assembly through the connecting side 2111 of the base 211 and causing the drive assembly to malfunction, thereby improving the reliability of the drive assembly.

[0056] like Figure 3 , Figure 4 and Figure 5 As shown, in the above embodiment, the support leg 212 includes a first side surface 2123 close to the top, that is, the support leg 212 includes a first side surface 2123 close to the connection side 2111, the bottom of the limiting boss 213 is in contact with the first side surface 2123, and the limiting boss 213 is provided with a guide surface 2131 on the side away from the connection position of the support leg 212 and the base 211, and the guide surface 2131 is inclined from the top to the bottom of the base 211 to the direction close to the connection position of the support leg 212 and the base 211. That is, the guide surface 2131 is provided on the side away from the first end 2121 of the limiting boss 213, and the guide surface 2131 is inclined from the top to the bottom of the base 211 to the direction close to the first end 2121.

[0057] The first side surface 2123 of the support leg 212 can be understood as the top of the support leg 212, that is, the side of the support leg 212 away from the surface to be cleaned, that is, the side of the support leg 212 facing upward, and most of the debris moving upward will move from the second end 2122 to the first end 2121 along the first side surface 2123 to gradually approach the connecting side 2111. The bottom of the limiting boss 213 is in contact with the first side surface 2123, so that when the debris moves from the second end 2122 to the first end 2121, it will be limited by the bottom of the limiting boss 213 before reaching the first end 2121, and will not continue to approach the first end 2121, thereby achieving the limiting effect. At the same time, by setting a guide surface 2131 on the side of the limiting boss 213 away from the first end 2121, the guide surface 2131 is inclined from the top to the bottom of the base 211 toward the direction close to the first end 2121, so that debris can be accumulated at the position of the guide surface 2131 and will not continue to move upward, so that the debris can be reliably limited below the limiting boss 213, thereby avoiding the possibility of debris entering the drive assembly through the connecting side 2111 of the base 211 and causing the drive assembly to malfunction, thereby extending the service life of the drive assembly and improving the reliability of the drive assembly.

[0058] like Figure 3 and Figure 5 As shown, in some possible embodiments provided by the present invention, the base 211 includes a first section 2112 along the axial direction, and a second section 2113 located at the bottom of the first section 2112, the connection side 2111 is located at a side of the first section 2112 away from the second section 2113, and the support leg 212 and the limiting boss 213 are arranged on the circumference of the second section 2113. This arrangement allows a certain distance between the connection side 2111 and the support leg 212, and a certain distance between the connection side 2111 and the limiting boss 213, thereby increasing the distance between the drive assembly and the support leg 212, and the distance between the drive assembly and the limiting boss 213, further reducing the possibility of debris entering the drive assembly, and helping to extend the service life of the drive assembly and improve the reliability of the drive assembly.

[0059] In some possible embodiments provided by the present invention, the radius of the end portion where the spiral leg 212 is connected to the base 211 is in the range of 15 mm to 20 mm. That is, the distance between the first end 2121 of the leg 212 and the rotation axis of the base 211 is in the range of 15 mm to 20 mm. Specifically, the radius of the end portion where the spiral leg 212 is connected to the base 211 can be 15 mm, 17 mm, 18 mm, 19 mm, 20 mm, or other sizes that meet the requirements. The diameter of the end portion where the spiral leg 212 is connected to the base 211 is as follows: Figure 3 As shown in D1.

[0060] The radius of the end of the spiral foot 212 away from the base 211 ranges from 55 mm to 60 mm, that is, the distance between the second end 2122 of the foot 212 and the rotation axis of the base 211 ranges from 55 mm to 60 mm. Specifically, the radius of the end of the spiral foot 212 away from the base 211 can be 55 mm, 56 mm, 58 mm, 59 mm, 60 mm, or other sizes that meet the requirements. By reasonably setting the radius of the end of the spiral foot 212 away from the base 211, it can be ensured that the side brush assembly 200 has a larger cleaning range to ensure a good cleaning effect. The diameter of the end of the spiral foot 212 away from the base 211 is as follows: Figure 3 As shown in D2.

[0061] The pitch of the spiral support leg 212 ranges from 55 mm to 60 mm. Specifically, the pitch of the spiral support leg 212 can be 55 mm, 56 mm, 58 mm, 59 mm, 60 mm, or other sizes that meet the requirements. By reasonably setting the pitch of the spiral support leg 212, the spiral shape of the support leg 212 is reasonable, which can better achieve the anti-entanglement effect, reduce the possibility of hair, wires and other debris being entangled on the support leg 212, and improve the overall anti-entanglement effect of the side brush assembly 200.

[0062] The number of spiral turns of the spiral support leg 212 is 0.7 to 0.8, specifically, the number of spiral turns of the spiral support leg 212 can be 0.7, 0.73, 0.75, 0.78, 0.79, 0.8, or other numbers that meet the requirements. By reasonably setting the number of spiral turns of the spiral support leg 212, the distance between the first end 2121 and the second end 2122 of the support leg 212 is reasonable, and the spiral shape of the support leg 212 is reasonable, which can better achieve the anti-entanglement effect, reduce the possibility of hair, wires and other debris being entangled on the support leg 212, and improve the overall anti-entanglement effect of the side brush assembly 200.

[0063] The height of the side brush assembly 200 ranges from 45 mm to 50 mm, wherein when the side brush assembly 200 includes bristles 220, the height of the side brush assembly 200 can be understood as the distance between the connection side 2111 of the base 211 of the side brush assembly 200 and the bottom end of the bristles 220 in the vertical direction, that is, the distance of the entire side brush assembly 200 along the vertical direction can be 45 mm to 50 mm. When the side brush assembly 200 does not include bristles 220, the height of the side brush assembly 200 can be understood as the distance between the connection side 2111 of the base 211 of the side brush assembly 200 and the bottom end of the support foot 212 in the vertical direction. Specifically, the height of the side brush assembly 200 in the vertical direction can be 45 mm, 46 mm, 48 mm, 49 mm, 50 mm, or other sizes that meet the requirements. By properly setting the height of the side brush assembly 200, the support foot 212 or the bristles 220 connected to the support foot 212 can reliably interfere with the surface to be cleaned to achieve a good cleaning effect, and the friction force thereof is within a reasonable range and does not affect the flexibility of the movement of the cleaning device 100. Figure 4 As shown in H.

[0064] The direction of the spiral leg 212 is clockwise, and correspondingly, the driving assembly drives the side brush body 210 to rotate counterclockwise. It is understandable that in other examples, the direction of the spiral involute can also be counterclockwise, and correspondingly, the driving assembly drives the side brush body 210 to rotate clockwise.

[0065] In some other possible embodiments provided by the present invention, the radius of the end portion where the spiral leg 212 is connected to the base 211 is in the range of 10 mm to 15 mm. That is, the distance between the first end 2121 of the leg 212 and the rotation axis of the base 211 is in the range of 10 mm to 15 mm. Specifically, the radius of the end portion where the spiral leg 212 is connected to the base 211 can be 10 mm, 11 mm, 13 mm, 14 mm, 15 mm, or other sizes that meet the requirements. The diameter of the end portion where the spiral leg 212 is connected to the base 211 is as follows: Figure 3 As shown in D1.

[0066] The radius of the end of the spiral foot 212 away from the base 211 is in the range of 60 mm to 70 mm, that is, the distance between the second end 2122 of the foot 212 and the rotation axis of the base 211 is in the range of 60 mm to 70 mm. Specifically, the radius of the end of the spiral foot 212 away from the base 211 can be 60 mm, 62 mm, 65 mm, 68 mm, 70 mm, or other sizes that meet the requirements. By reasonably setting the radius of the end of the spiral foot 212 away from the base 211, it can be ensured that the side brush assembly 200 has a larger cleaning range to ensure a good cleaning effect. The diameter of the end of the spiral foot 212 away from the base 211 is as follows: Figure 3 As shown in D2.

[0067] The pitch of the spiral foot 212 ranges from 50 mm to 55 mm. Specifically, the pitch of the spiral foot 212 can be 50 mm, 51 mm, 53 mm, 54 mm, 55 mm, or other sizes that meet the requirements. By properly setting the pitch of the spiral foot 212, the spiral shape of the foot 212 is reasonable, and has a good anti-entanglement effect, thereby reducing the possibility of hair, wires and other debris being entangled on the foot 212, and improving the overall anti-entanglement effect of the side brush assembly 200.

[0068] The number of spiral turns of the spiral support leg 212 is 0.6 to 0.7, specifically, the number of spiral turns of the spiral support leg 212 can be 0.6, 0.63, 0.65, 0.68, 0.69, 0.7, or other numbers that meet the requirements. By reasonably setting the number of spiral turns of the spiral support leg 212, the distance between the first end 2121 and the second end 2122 of the support leg 212 is reasonable, and the spiral shape of the support leg 212 is reasonable, which has a good anti-entanglement effect, thereby reducing the possibility of hair, wires and other debris being entangled on the support leg 212, and improving the overall anti-entanglement effect of the side brush assembly 200.

[0069] The height of the side brush assembly 200 ranges from 40 mm to 45 mm, wherein when the side brush assembly 200 includes bristles 220, the height of the side brush assembly 200 can be understood as the distance between the connection side 2111 of the base 211 of the side brush assembly 200 and the bottom end of the bristles 220 in the vertical direction, that is, the distance of the entire side brush assembly 200 along the vertical direction can be 40 mm to 45 mm. When the side brush assembly 200 does not include bristles 220, the height of the side brush assembly 200 can be understood as the distance between the connection side 2111 of the base 211 of the side brush assembly 200 and the bottom end of the support foot 212 in the vertical direction. Specifically, the height of the side brush assembly 200 in the vertical direction can be 40 mm, 41 mm, 43 mm, 44 mm, 45 mm, or other sizes that meet the requirements. By properly setting the height of the side brush assembly 200, the support legs 212 or the bristles 220 can reliably interfere with the surface to be cleaned to achieve a good cleaning effect, and the friction force thereof is within a reasonable range and does not affect the flexibility of the movement of the cleaning device 100. Figure 4 As shown in H.

[0070] The direction of the spiral leg 212 is clockwise, and correspondingly, the driving assembly drives the side brush body 210 to rotate counterclockwise. It is understandable that in other examples, the direction of the spiral involute can also be counterclockwise, and correspondingly, the driving assembly drives the side brush body 210 to rotate clockwise.

[0071] In the specific example provided by the present invention, the radius of the end of the spiral foot 212 connected to the base 211 is 17 mm; the radius of the end of the spiral foot 212 away from the base 211 is 58 mm, the pitch of the spiral foot 212 is 57.5 mm, the number of spiral turns of the spiral foot 212 is 0.75 turns, and when the side brush assembly 200 includes bristles 220, the height of the side brush assembly 200 is 43 mm, and the direction of the spiral foot 212 is clockwise, thereby making the side brush assembly 200 have a good anti-entanglement effect and can ensure a good cleaning effect.

[0072] In some possible embodiments provided by the present invention, the bristles 220 can be connected to the support leg 212 by bonding. Thus, the bristles 220 and the support leg 212 can be reliably connected, reducing the risk of the bristles 220 falling off during the operation of the side brush assembly 200, and improving the reliability and service life of the side brush assembly 200. In addition, the bristles can also be connected to the support leg 212 by plugging, snapping, mortise and tenon, screwing, etc., and the present invention does not make specific restrictions on this.

[0073] Furthermore, if Figure 5As shown, a receiving groove 2124 is provided on the end surface of the end of the support leg 212 away from the base 211, that is, a receiving groove 2124 is provided on the end surface of the second end 2122 of the support leg 212, and one end of the bristle 220 is received in the receiving groove 2124 and connected to the receiving groove 2124 through an adhesive, so that the bristle 220 can be reliably bonded to the end of the support leg 212 away from the base 211. At the same time, since the receiving groove 2124 is located on the end surface of the end of the support leg 212 away from the base 211, the side wall between the two ends of the support leg 212 is smoothly transitioned, that is, the side wall between the first end 2121 and the second end 2122 of the support leg 212 does not have a groove, a protrusion or other structure for connecting the bristles as in the side brush assembly in the related art. Therefore, compared with the side brush assembly in the related art, the phenomenon that the groove, the protrusion or other structure hooks the hair, the thread or other debris can be avoided.

[0074] In some possible embodiments provided by the present invention, the side brush body 210 is a rubber part with a smooth surface. The side brush body 210 made of rubber can reduce the possibility of hair and thread-like debris being entangled on the side brush body 210, thereby reducing the possibility of hair and thread-like debris being entangled on the side brush assembly 200, and has a good anti-entanglement effect. At the same time, the side brush body 210 made of rubber has a certain elasticity and good deformation ability, so that the side brush body 210 can better and more thoroughly bounce off the hair and thread-like debris entangled on the support foot 212, and has a good anti-entanglement function. In addition, the side brush body 210 made of rubber can make the support foot 212 or the bristles 220 reliably interfere with the surface to be cleaned to ensure a good cleaning effect, and can make the friction between the support foot 212 or the bristles 220 and the surface to be cleaned within an appropriate range, so that the cleaning device 100 can move flexibly.

[0075] Further, the hardness of the side brush body 210 is 75HB to 85HB. The hardness of the side brush body 210 is reasonably set so that the side brush body 210 has good elasticity and good wear resistance, so as to ensure that the side brush body 210 has a good anti-winding effect and can extend the service life of the side brush body 210. Specifically, the hardness of the side brush body 210 can be 75HB, 77HB, 80HB, 82HB, 84HB, 85HB, or other values.

[0076] In some possible embodiments provided by the present invention, the base 211 is provided with a connection hole for connecting to the drive assembly along the axial direction. It is understandable that the side brush assembly 200 may also include a connector, which is configured to pass through the connection hole and connect to the drive assembly. Thus, the side brush assembly 200 can be connected to the drive assembly through the connector, so that the drive assembly drives the side brush assembly 200 to rotate relative to the machine body 110.

[0077] Specifically, the connecting piece can be a screw, and the driving assembly includes a motor. A threaded hole is provided on the output shaft of the motor. The screw passes through the connecting hole on the base 211 and is connected to the threaded hole on the output shaft, so that the side brush assembly 200 can be connected to the driving assembly. The operation is simple and the disassembly and assembly are convenient, thereby improving the maintenance efficiency and replacement efficiency of the side brush assembly 200 and facilitating user operation.

[0078] like Figure 2 As shown, the cleaning device 100 provided by the utility model has a side brush assembly 200 located at the bottom of the main body 110. Furthermore, the side brush assembly 200 can also be located in front of the dust box. Specifically, in the moving direction of the cleaning device 100, the side brush assembly 200 is located in front of the dust box. In this way, during the moving process of the cleaning device 100, the side brush assembly 200 located in front of the dust box will first guide the debris outside the roller brush area to the direction close to the dust box, move the debris into the roller brush area, and then make the debris recovered into the dust box by the roller brush, so as to improve the cleaning effect of the cleaning device 100.

[0079] In some examples provided by the present invention, the number of the side brush assembly 200 can be one, located on the left or right side of the bottom of the main body 110, so that the side brush assembly 200 can guide debris from the left front or right front of the cleaning device 100 to the roller brush area, thereby ensuring that the cleaning device 100 has a good cleaning effect and can reduce manufacturing costs, which is suitable for popularization and application. Specifically, Figure 2 As shown, the side brush assembly 200 is located at the front right of the bottom of the machine body 110 .

[0080] In other examples provided by the present invention, the number of side brush assemblies 200 can be two, and the two side brush assemblies 200 are distributed on the left and right sides of the bottom of the machine body 110. Thus, the two side brush assemblies 200 respectively guide debris from the left front or the front of the cleaning device 100 to the roller brush area, thereby greatly improving the cleaning effect of the cleaning device 100.

[0081] Furthermore, the spiral directions of the legs 212 of the two side brush assemblies 200 are opposite, wherein the spiral direction of the legs 212 in each side brush assembly 200 is from outside to inside relative to the main body 110. For example, the spiral direction of the legs 212 of the side brush assembly 200 located at the right front of the bottom of the main body 110 is clockwise, and the driving assembly drives the side brush assembly 200 to rotate counterclockwise. The spiral direction of the legs 212 of the side brush assembly located at the left front of the bottom of the main body 110 is counterclockwise, and the driving assembly drives the side brush assembly 200 to rotate clockwise.

[0082] The utility model has been described through the above embodiments, but it should be understood that the above embodiments are only for the purpose of example and description, and are not intended to limit the utility model to the scope of the described embodiments. In addition, it can be understood by those skilled in the art that the utility model is not limited to the above embodiments, and more variations and modifications can be made according to the teachings of the utility model, and these variations and modifications all fall within the scope of protection claimed by the utility model. The protection scope of the utility model is defined by the attached claims and their equivalents.
