Detailed Implementation

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0029] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0030] The side brush mechanism and cleaning equipment provided by this utility model will be described in detail below with reference to the embodiments.

[0031] Please see Figure 1 , Figure 2 as well as Figure 3 , Figure 1 This is a structural schematic diagram of the gearbox assembly in the side brush mechanism of this application; Figure 2 This is a partial schematic diagram of the cleaning components in the side brush mechanism of this application; Figure 3 This is a cross-sectional schematic diagram of the cleaning component in the side brush mechanism of this application. This application provides a side brush mechanism. The side brush mechanism 10 includes a gearbox assembly 12 and a cleaning component 13. The gearbox assembly 12 includes a gearbox housing 123 and a rotary drive member 121 connected to the gearbox housing 123. An abutment member 1232 is provided at one end of the gearbox housing 123 opposite to the rotary drive member 121. The cleaning component 13 includes a cleaning housing 131, a floating member 132, an elastic member 133, and bristle members 134. The rotary drive member 121 drives the cleaning housing 131 to rise or fall. The abutment member 1232 is releasably abutted against the floating member 132. The elastic member 133 is disposed in the cleaning housing 131. One end of the bristle member 134 abuts between the floating member 132 and the elastic member 133. The other end of the bristle member 134 passes through the cleaning housing 131 and extends out of the cleaning housing 131.

[0032] The gearbox housing 123 provides a mounting position for the rotary drive component 121. The rotary drive component 121 is detachably or fixedly connected to the gearbox housing 123. The rotary drive component 121 may be, but is not limited to, a rotary drive motor. The abutment member 1232 is detachably or fixedly connected to the gearbox assembly 12. The abutment member 1232 protrudes from one end face of the gearbox assembly 12 facing the cleaning component 13.

[0033] The cleaning housing 131 provides mounting positions for the aforementioned floating member 132, elastic member 133, and bristle member 134. The rotary drive member 121 drives the cleaning housing 131 to rise, meaning the rotary drive member 121 drives the cleaning assembly 13 to rise and move away from the surface to be cleaned. The rotary drive member 121 also drives the cleaning housing 131 to descend, meaning the rotary drive member 121 drives the cleaning assembly 13 to descend and move closer to the surface to be cleaned. The rotary drive member 121 can directly drive the cleaning housing 131 to rise or fall; alternatively, it can indirectly drive the cleaning housing 131 to rise or fall, and this is not limited to any particular method.

[0034] The abutment member 1232 can abut against the floating member 132; or, the abutment member 1232 can disengage from the floating member 132. One upper end of the bristle member 134 abuts against the bottom surface of the floating member 132. The lower end of one end of the bristle member 134 abuts against the surface of the elastic member 133. The other end of the bristle member 134 passes through the cleaning housing 131 and extends beyond the exterior of the cleaning housing 131. The bristle member 134 is capable of cleaning the surface to be cleaned. The surface to be cleaned can be, but is not limited to, the ground and carpets.

[0035] As the rotating drive 121 drives the cleaning assembly 13 to rise, the abutting member 1232 gradually abuts against the floating member 132, and the floating member 132 squeezes one end of the bristle member 134 and the elastic member 133. At this time, the other end of the bristle member 134 gradually moves away from the surface to be cleaned, and then completely moves away from the surface to be cleaned.

[0036] As the rotating drive 121 drives the cleaning component 13 to descend, the abutting component 1232 gradually releases from contact with the floating component 132, the floating component 132 releases its pressure on one end of the bristle component 134, and the elastic component 133 returns to its original state. At this time, the other end of the bristle component 134 is close to the surface to be cleaned.

[0037] Through the combined action of the gearbox housing 123, the rotary drive component 121, the abutment component 1232, the cleaning housing 131, the floating component 132, the elastic component 133, and the bristle component 134, during the upward movement of the cleaning component 13, the floating component 132 acts on one end of the bristle component 134 and causes the bristle component 134 to rotate, so that the other end of the bristle component 134 can be completely detached from the surface to be cleaned, thereby reducing secondary contamination of the surface to be cleaned by the cleaning component 13 and improving cleaning efficiency.

[0038] Please see Figure 4 and Figure 5 , Figure 4 yes Figure 3 An enlarged schematic diagram of A shown; Figure 5 This is a structural schematic diagram of the elastic element in the edge brush mechanism of this application. (Combined with...) Figures 1 to 3In some embodiments, the elastic member 133 includes a support portion 1331 and a deformation portion 1332 connected to the support portion 1331. The support portion 1331 is connected within the cleaning housing 131. One end of the bristle member 134 elastically abuts against the deformation portion 1332 and the floating member 132.

[0039] The support portion 1331 and the deformation portion 1332 are detachably or fixedly connected. In this embodiment, the support portion 1331 and the deformation portion 1332 are integrally formed. The support portion 1331 is detachably or fixedly connected within the cleaning housing 131. The support portion 1331 provides the deformation portion 1332 with an installation position and related support force. The deformation portion 1332 can deform under force. One lower end of the bristle member 134 elastically abuts against the deformation portion 1332, and one upper end of the bristle member 134 abuts against the floating member 132.

[0040] Through the combined action of the support 1331, the deformation part 1332 and the bristle part 134, an elastic force can be provided to the bristle part 134, so that the bristle part 134 rises and completely detaches from the surface to be cleaned.

[0041] In some embodiments, the deformable portion 1332 includes a plurality of sub-deformable portions 1332. The sub-deformable portions 1332 are bent toward the center of the cleaning housing 131. One end of the bristle member 134 elastically abuts against the corresponding sub-deformable portion 1332 and the floating member 132.

[0042] The deformable part 1332 can be an integral structure or a separate structure. When the deformable part 1332 is an integral structure, multiple bristle parts 134 abut against the floating part 132 and the deformable part 1332.

[0043] When the deformable part 1332 is a split structure, it includes multiple sub-deformable parts 1332. The number of sub-deformable parts 1332 can be, but is not limited to, one, two, or more than three. When there are multiple sub-deformable parts 1332, adjacent sub-deformable parts 1332 are spaced apart. The multiple sub-deformable parts 1332 are bent toward the center of the cleaning housing 131. The number of sub-deformable parts 1332 is the same as the number of bristle members 134. In this embodiment, both the number of sub-deformable parts 1332 and the number of bristle members 134 are three. Each bristle member 134 has one end elastically abutting between the corresponding sub-deformable part 1332 and the floating member 132.

[0044] Through the combined action of the aforementioned sub-deformation part 1332, bristle part 134, and floating part 132, elastic force can be provided to the corresponding bristle part 134, so that the bristle part 134 rises and completely detaches from the surface to be cleaned.

[0045] In some embodiments, the cleaning housing 131 is provided with a lifting connection portion 1311. The support portion 1331 and the floating member 132 are both sleeved on the lifting connection portion 1311. The gearbox assembly 12 is provided with a lifting portion 1233. The lifting portion 1233 is connected to the lifting connection portion 1311. The rotary drive member 121 drives the lifting portion 1233 and the lifting connection portion 1311 to rise or fall.

[0046] The lifting connection 1311 is detachably or fixedly connected to the cleaning housing 131. For example, the lifting connection 1311 is located in the middle of the cleaning housing 131. The support part 1331 is provided with a support hole 13311. The support part 1331 is fitted onto the outer periphery of the lifting connection 1311 through the support hole 13311. The floating member 132 is provided with a floating hole 1322. The floating member 132 is fitted onto the outer periphery of the lifting connection 1311 through the floating hole 1322. The floating member 132 is located above the support part 1331.

[0047] The lifting part 1233 is detachably or fixedly connected to the gearbox assembly 12. For example, the lifting part 1233 may be located within the gearbox housing 123. The drive shaft of the rotary drive member 121 may be connected to the lifting part 1233; or, the drive shaft of the rotary drive member 121 may be spaced apart from the lifting part 1233. The rotary drive member 121 can change the direction of rotation, allowing the lifting part 1233 to rotate forward or backward. The lifting part 1233 is detachably or fixedly connected to the lifting connection part 1311.

[0048] Specifically, the lifting part 1233 may be, but is not limited to, a lifting shaft (not shown in the figure). The lifting connecting part 1311 may be, but is not limited to, a lifting connecting groove (not shown in the figure). The lifting shaft is connected to the lifting connecting groove. The cross-sectional shape of the lifting shaft may be the same as the cross-sectional shape of the lifting connecting groove. For example, both the cross-sectional shapes of the lifting shaft and the lifting connecting groove may be hexagonal.

[0049] When the rotary drive 121 drives the lifting part 1233 to rotate forward and rise, the lifting part 1233 drives the lifting connecting part 1311 to rise, so that the cleaning component 13 rises and detaches from the surface to be cleaned. When the rotary drive 121 drives the lifting part 1233 to rotate in the opposite direction and descend, the lifting part 1233 drives the lifting connecting part 1311 to descend, so that the cleaning component 13 descends and approaches the surface to be cleaned.

[0050] Through the combined action of the lifting connection 1311, support 1331, floating component 132 and lifting part 1233, the cleaning component 13 can not only rise or fall, but also has a compact structure and can reduce space occupation.

[0051] Please see Figure 6 as well as Figure 7 , Figure 6 This is a partial schematic diagram of the brush component in the edge brush mechanism of this application; Figure 7 yes Figure 6 An enlarged schematic diagram of C is shown. (Combined with...) Figures 1 to 5 In some embodiments, the bristle member 134 includes a bristle connecting portion 1341 and a bristle portion 1342 connected to the bristle connecting portion 1341. A portion of the bristle connecting portion 1341 abuts between the floating member 132 and the elastic member 133. Another portion of the bristle connecting portion 1341 passes through the cleaning housing 131. The bristle portion 1342 extends outside the cleaning housing 131.

[0052] The bristle connecting portion 1341 is detachably or fixedly connected to the bristle portion 1342. A portion of the bristle connecting portion 1341 abuts against the floating member 132 and the elastic member 133. For example, the upper end of a portion of the bristle connecting portion 1341 abuts against the bottom end of the floating member 132; the lower end of a portion of the bristle connecting portion 1341 abuts against the surface of the elastic member 133. Another portion of the bristle connecting portion 1341 passes through the cleaning housing 131. The bristle portion 1342 extends beyond the cleaning housing 131. The bristle connecting portion 1341 has a certain degree of rigidity. The bristle connecting portion 1341 can be made of, but is not limited to, materials such as plastic, metal, and alloy.

[0053] By integrating the elastic element 133 and the floating element 132 into the cleaning housing 131, it can not only act on one end of the bristle 134 to make the bristle 134 rotate so that the other end of the bristle 134 is away from the surface to be cleaned; but also has a compact structure and reduces space occupation.

[0054] In some embodiments, the bristle connector 1341 includes a sub-connector 13411. The sub-connector 13411 includes a first connecting surface 13411a and a second connecting surface 13411b connected to the first connecting surface 13411a. The first connecting surface 13411a is planar and abuts against the floating member 132, and the second connecting surface 13411b is inclined and abuts against the elastic member 133.

[0055] The first connecting surface 13411a is located at the top of the sub-connecting portion 13411. The second connecting surface 13411b is located on the side of the sub-connecting portion 13411. One end of the first connecting surface 13411a and one end of the second connecting surface 13411b are connected. The first connecting surface 13411a is planar and abuts against the bottom surface of the floating member 132. The second connecting surface 13411b is inclined and abuts against the deformable portion 1332 of the elastic member 133.

[0056] The structure of the first connecting surface 13411a and the second connecting surface 13411b of the sub-connecting part 13411 can improve the stability of the brush bristle 134 rotating within the cleaning housing 131, thereby improving the stability of the brush bristle 134 completely detaching from the surface to be cleaned.

[0057] In some embodiments, the sub-connecting portion 13411 further includes a third connecting surface 13411c. The third connecting surface 13411c is connected to the first connecting surface 13411a. The third connecting surface 13411c is in close contact with the inner sidewall of the cleaning housing 131. And / or, the bristle connecting portion 1341 includes a rotating portion 13412. The rotating portion 13412 is connected to the sub-connecting portion 13411. The cleaning housing 131 is provided with a through-hole rotating groove 1312. The rotating portion 13412 passes through the rotating groove 1312 and rotates relative to the rotating groove 1312.

[0058] The third connecting surface 13411c is located on the other side of the sub-connecting portion 13411. One end of the third connecting surface 13411c is connected to one end of the first connecting surface 13411a. The third connecting surface 13411c is tightly fitted against the inner wall of the cleaning housing 131. The third connecting surface 13411c and the inner wall of the cleaning housing 131 are arranged parallel to each other. Because the first connecting surface 13411a is planar and abuts against the bottom surface of the floating member 132, and because the bottom surface of the floating member 132 is perpendicular to the inner wall of the cleaning housing 131, in this embodiment, the third connecting surface 13411c can be perpendicular to the first connecting surface 13411a.

[0059] The rotating part 13412 is detachably or fixedly connected to the sub-connecting part 13411. In this embodiment, the rotating part 13412 and the sub-connecting part 13411 are integrally formed and connected. A rotating groove 1312 is provided through the cleaning housing 131. There is one rotating groove 1312, which extends circumferentially along the cleaning housing 131. Multiple bristle pieces 134 rotate at different positions within the same rotating groove 1312. Alternatively, there are multiple rotating grooves 1312. These multiple rotating grooves 1312 are spaced apart circumferentially along the cleaning housing 131. Each bristle piece 134 rotates within its corresponding rotating groove 1312. During the up-and-down movement of the floating part 132, the bristle pieces 134 oscillate up and down with the floating part 132.

[0060] The third connecting surface 13411c enhances the contact between the bristle 134 and the floating part 132 and the deformable part 1332. And / or, through the combined action of the rotating part 13412, the sub-connecting part 13411, and the rotating groove 1312, the stability of the bristle 134 rotating within the cleaning housing 131 is further improved, thereby enhancing the stability of the bristle 134 completely detaching from the surface to be cleaned.

[0061] Please see Figure 8 , Figure 8 This is a schematic diagram of the elastic section in the edge brush mechanism of this application. (Combined with...) Figures 1 to 7 In some embodiments, the bristle member 134 includes an elastic portion 1343. The elastic portion 1343 is connected between the bristle connecting portion 1341 and the bristle portion 1342.

[0062] In this embodiment, one end of the elastic portion 1343 is detachably or fixedly connected to the bristle connecting portion 1341. The other end of the elastic portion 1343 is detachably or fixedly connected to the bristle portion 1342. As in this embodiment, one end of the elastic portion 1343 is glued to the bristle connecting portion 1341, and the other end of the elastic portion 1343 is glued to the bristle portion 1342. The elastic portion 1343 is elastic. The elastic portion 1343 may be made of a soft rubber material.

[0063] By providing an elastic portion 1343 between the bristle connector 1341 and the bristle portion 1342, the two ends of the elastic portion 1343 can be directionally tortuous with the connecting ends of the bristle connector 1341 and the bristle portion 1342, respectively. When the bristle portion 1342 encounters an obstacle, the elastic portion 1343 is more likely to deform, thereby reducing the risk of damage to the bristle component 134 and extending its service life.

[0064] Specifically, one end of the bristle connecting part 1341 is inserted into one end of the elastic part 1343 and connected by an adhesive coating. The bristle part 1342 is inserted into the other end of the elastic part 1343 and connected by an adhesive coating.

[0065] Please see Figure 9 and Figure 10 , Figure 9 yes Figure 3 An enlarged schematic diagram of B is shown below; Figure 10 This is a structural schematic diagram of the floating component in the edge brush mechanism of this application. (Combined with...) Figures 1 to 8 In some embodiments, the floating member 132 has a plurality of floating portions 1321 around its periphery. The cleaning housing 131 includes a first cleaning housing 131a and a second cleaning housing 131b connected to the first cleaning housing 131a. The floating portions 1321 are slidable along the inner sidewalls of the first cleaning housing 131a and the second cleaning housing 131b.

[0066] The floating part 1321 is detachably or fixedly connected to the periphery of the floating member 132. The number of floating parts 1321 can be, but is not limited to, two, three, or more than four. In this embodiment, there are three floating parts 1321, which are evenly distributed circumferentially around the periphery of the floating part 1321. During the process of the elastic member 133 returning to its original shape, the elastic member 133 drives the floating part 1321 to move upward.

[0067] The first cleaning shell 131a and the second cleaning shell 131b can be detachably or fixedly connected. As in this embodiment, the first cleaning shell 131a and the second cleaning shell 131b can be connected by, but is limited to, ultrasonic welding or adhesive dispensing.

[0068] When the abutting member 1232 abuts against the floating member 132, the floating part 1321 on the floating member 132 slides along the inner sidewall of the first cleaning shell 131a and the inner sidewall of the second cleaning shell 131b. Specifically, the inner sidewall of the first cleaning shell 131a and the inner sidewall of the second cleaning shell 131b are provided with multiple sliding grooves (not shown in the figure). The number of sliding grooves can be the same as the number of floating parts 1321. The floating parts 1321 are slidably connected in the corresponding sliding grooves.

[0069] Through the combined action of the floating component 132, the floating part 1321, the first cleaning shell 131a, and the second cleaning shell 131b, the stability of the floating component 132's up-and-down movement is improved, thereby enhancing the stability of the bristle component 134 when it rises or falls.

[0070] In some embodiments, the lifting connection portion 1311 is disposed in the middle of the second cleaning housing 131b. The lifting portion 1233 is connected to the lifting connection portion 1311 and locked by a fastener, so that the lifting portion 1233 can drive the cleaning assembly 13 to rise or fall, etc. The fastener may be, but is not limited to, a fixing bolt or a fixing screw.

[0071] In some embodiments, the abutment 1232 can be a single unit. That is, one abutment 1232 can abut against the floating member 132. Alternatively, the abutment 1232 may include a plurality of abutment portions (not shown in the figures). Adjacent abutment portions are spaced apart. The abutment portions abut against the floating member 132, etc. The annular abutment portions can abut against the floating member 132; or, the annular abutment portions can disengage from the floating member 132.

[0072] In some embodiments, the gearbox assembly 12 includes a gear assembly (not shown in the figures). A rotary drive 121 is connected to the gear assembly. The gear assembly is connected to the lifting part 1233. The gear assembly includes at least a drive gear (not shown in the figures), an nth gear (not shown in the figures), and a connecting gear (not shown in the figures). The drive gear meshes with the nth gear, and the nth gear meshes with and connects to the connecting gear. The connecting gear connects to the lifting part 1233. The rotary drive 121 drives the gear assembly to move, and the gear assembly causes the lifting part 1233 to rise or fall.

[0073] In some embodiments, the gearbox assembly 12 includes a gearbox housing 123. The gearbox housing 123 includes a first gearbox housing 123a and a second gearbox housing 123b. The first gearbox housing 123a and the second gearbox housing 123b are detachably or fixedly connected. An abutment member 1232 is disposed on a side of the second gearbox housing 123b opposite to the first gearbox housing 123a. A rotation drive member 121 is disposed on the first gearbox housing 123a.

[0074] Continue reading Figures 1 to 10 In a specific application scenario, the floating part 1321 of the floating member 132 can slide along the grooves on the inner sidewalls of the first cleaning shell 131a and the second cleaning shell 131b. The floating member 132 abuts against the first connecting surface 13411a of the bristle connecting part 1341, and the elastic member 133 abuts against the second connecting surface 13411b of the bristle connecting part 1341. The rotating part 13412 is engaged in the rotating groove 1312 of the cleaning shell 131 and can swing up and down along the rotating groove 1312. The lifting connecting part 1311 of the second cleaning shell 131b is connected to the lifting part 1233 in the gearbox assembly 12, and the cleaning assembly 13 can move up and down with the lifting part 1233.

[0075] As the lifting part 1233 rises, the abutting part 1232 of the gearbox assembly 12 contacts the floating part 132 and gradually compresses the floating part 132 downward. As the floating part 132 moves downward, the abutting part of the sub-connecting part 13411 of the bristle connecting part 1341 and the floating part 132 also moves downward. The elastic part 133 is under pressure, and the deformable part 1332 of the elastic part 133 is deformed downward under pressure. The rotating part 13412 of the bristle connecting part 1341 is limited by the rotating groove 1312 and can only swing upward. The rotating part 13412 drives the elastic part 1343 and the bristle part 1342 to swing upward, so that the bristle part 1342 is completely separated from the surface to be cleaned. Among them, the bristle part 134 is at the far end of the rotating part 13412, and the bristle connecting part 1341 is at the near end. As the rotating part 13412 swings up and down, the small-distance floating of the bristle connecting part 1341 can realize the long-distance up and down movement of the bristle part 1342.

[0076] As the lifting part 1233 descends, the cleaning component 13 moves downward, and the floating part 132 is no longer squeezed by the abutment part 1232. The floating part 132 and the bristle connection part 1341 move upward under the action of the elastic part 133, and the rotating part 13412 swings downward synchronously, so that the bristle part 1342 contacts the surface to be cleaned.

[0077] Please see Figures 1 to 10This application provides a cleaning device. The cleaning device (not shown in the figure) includes a cleaning device body (not shown in the figure) and a side brush mechanism 10. The side brush mechanism 10 is disposed on the cleaning device body.

[0078] The cleaning equipment may include, but is not limited to, sweeping machines, robotic vacuum cleaners, and combined sweeping and mopping machines. The side brush mechanism 10 is detachably connected to the bottom of the cleaning equipment body. It should be noted that the side brush mechanism 10 in this embodiment is the same as the side brush mechanism 10 described in the above embodiments, and is not limited thereto.

[0079] The cleaning equipment of this application, through the aforementioned side brush mechanism 10, during the upward movement of the cleaning component 13, the floating component 132 acts on one end of the bristle component 134 and causes the bristle component 134 to rotate, so that the other end of the bristle component 134 can be completely detached from the surface to be cleaned, thereby reducing secondary contamination of the surface to be cleaned by the cleaning component 13 and thus improving cleaning efficiency.
