[0023] 1. In the support assembly provided by the present invention, the first button is movably arranged on the support frame and can be connected to or separated from the shell. That is, one end of the support frame is detachably connected to the shell, and the other end of the support frame is detachably connected to the shell through the first button. Therefore, in the support assembly, the support frame can be disassembled by only driving the first button to move and separate from the shell, and the disassembly process is simpler.

[0024] 2. In the support assembly provided by the present invention, the support frame includes a first frame, a second frame and a first elastic member, and the first elastic member elastically pushes the first frame and the second frame in a direction away from each other.

When the first button is forced to move to the first unlocking position, it is separated from the first buckle. Relative to the first frame, the movement direction of the first button is perpendicular to the movement direction of the second frame, so the relative movement of the first frame and the second frame will not drive the first button to move relative to the first frame. Therefore, when the second frame moves in a direction close to the first frame, the first buckle is engaged with the first button, so that the second frame and the first frame can be kept at a relatively close distance. In this way, it is convenient to insert the support frame into the cleaning member. When the first button moves to the first unlocking position, the first button is separated from the first buckle, so the first frame and the second frame move in a direction away from each other under the action of the first elastic member to open the cleaning member. That is to say, in the support assembly provided by the present invention, the first button is not only used to connect and disconnect the support frame with the housing, but also can unlock and lock the first bracket and the second bracket. This arrangement makes the overall structure of the support assembly simpler and more compact, making it easier to install the support assembly into the cleaning member.

DETAILED DESCRIPTION

[0043] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0044] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0045] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0046] The inventor of the present application has found that the cleaning robot with a cleaning structure such as a mop in the conventional technology usually has a cleaning structure that is detachably mounted on a housing, so that the cleaning structure can be disassembled and the cleaning structure itself can be cleaned. At present, a common installation method for the cleaning structure is to set a mounting groove on the housing and install the cleaning member in the mounting groove. The support extends outside the mounting groove to connect with the structure outside the mounting groove to avoid interfering with the movement of the cleaning member in the mounting groove. Since the cleaning structure as a whole is not completely located in the mounting groove, and there is a height difference between the inside and outside of the mounting groove, it is necessary to adjust the relative position of the cleaning structure and the mounting groove during the assembly process of the cleaning equipment so that the two can be correctly aligned. However, the cleaning structure usually has a relatively large structural size and a relatively large weight. In the process of adjusting the alignment of the cleaning structure and the mounting groove and placing the cleaning structure in the mounting groove, fingers are easily pinched by the housing and the cleaning structure.

[0047] In order to solve the above problems, the present invention proposes a support assembly, which is used to support a cleaning member. The support assembly includes a support frame and a first button, and the first button is movably disposed at one end of the support frame. One end of the support frame is plugged into the shell, and the other end of the support frame is plugged into the shell through the first button. The two ends of the support frame are connected to the shell by plugging. When installing, the support frame can first extend one end into the installation groove and align it with the corresponding hole on the shell, and then press the other end of the support frame into the installation groove, so that the two ends of the support frame can be plugged in and installed step by step. The installation process is simple and the risk of pinching fingers is greatly reduced. The support assembly, cleaning device and cleaning equipment provided by the present invention will be described in detail below in conjunction with specific implementation methods and drawings in the specification.

[0048] Example 1

[0049] This embodiment provides a support assembly for supporting a cleaning member. Figure 1 and Figure 2 As shown, the support assembly 22 includes a support frame 100 and a first button 200. One end of the support frame 100 is used to be detachably connected to the housing 10, and the first button 200 is movably disposed at the other end of the support frame 100 and is used to be connected to or separated from the housing 10.

[0050] In the above-mentioned support assembly 22, the first button 200 is movably disposed on the support frame 100 and can be connected to the housing 10. Thus, one end of the support frame 100 is detachably connected to the housing 10, and the other end of the support frame 100 is detachably connected to the housing 10 through the first button 200, so that the support frame 100 can remain relatively fixed with the housing 10. When it is necessary to remove the support frame 100 from the housing 10, by driving the first button 200 to move relative to the support frame 100 and separate from the housing 10, one end of the support frame 100 can be disconnected from the housing 10, so that the other end of the support frame 100 can be further removed from the housing 10, so that the two ends of the support frame 100 can be removed from the housing 10 step by step. With such a configuration, in the support assembly 22, the disassembly of the support frame 100 can be completed by only driving the first button 200 to move, and the disassembly process is simpler.

[0051] In one embodiment, one end of the support frame 100 can be detachably connected to the housing 10 by plugging. The first button 200 is retractably arranged at the other end of the support frame 100 for plugging in or separating from the housing 10. By plugging, there is no need to set an additional connection structure for the connection between the support assembly 22 and the housing 10, so that the overall structure of the support assembly 22 is simpler and easy to disassemble. It can be understood that the first button 200 is used to plug in the housing 10 when it is extended, and is separated from the housing 10 when the first button 200 is retracted.

[0052] Of course, in other embodiments, the support frame 100 can also be detachably connected to the housing 10 by other means such as snaps. For ease of understanding and description, the following description is based on the example that the support frame 100 and the first button 200 are connected to the housing 10 by plugging.

[0053] In one embodiment, a mounting groove 11 is provided on the housing 10, and the support assembly 22 is plugged into and matched with the groove wall of the mounting groove 11. Since the first button 200 is movably arranged on the support frame 100, during installation, the first button 200 can avoid the structure that may interfere with the mounting groove 11 when moving relative to the support frame 100, and move in the opposite direction when installed in place to plug into the groove wall of the mounting groove 11 to complete the installation. During disassembly, the first button 200 moves relative to the support frame 100 until it is out of the plug-in relationship with the groove wall of the mounting groove 11, and then one end of the support frame 100 provided with the first button 200 can be removed from the mounting groove 11, and then the other end of the support frame 100 can also be pulled out of the mounting groove 11 to complete the disassembly. The overall disassembly and assembly process can be achieved through the first button 200, and the disassembly and assembly are convenient.

[0054] Of course, the support assembly 22 is not limited to being installed in the installation groove 11. As long as the support frame 100 can be disassembled and assembled at both ends in steps through the first button 200, it can facilitate the installation of the support assembly 22 and reduce the risk of pinching fingers.

[0055] In one embodiment, the cleaning member 21 may be a mop. For example, when the cleaning member 21 is a crawler mop, the support frame 100 may be provided with a mop, and the mop can be conveniently connected or separated from the housing 10 through the support frame 100, so as to clean the mop itself. The cleaning member 21 may also be a cylindrical structure with bristles. When the cleaning member 21 is mounted on the support frame 100, it can form a rolling brush together with the support frame 100 to clean the surface to be cleaned such as the ground or the wall. Of course, the cleaning member 21 may also be other cleaning elements with detachable requirements.

[0056] See also Figure 1 and Figure 3 In one embodiment, the support frame 100 is used to penetrate the cleaning member 21 to support the cleaning member 21 in a roughly flat state to mop and clean the ground and other working surfaces. The support frame 100 includes a first bracket 110, a second bracket 120 and a first elastic member 130. The first bracket 110 and the second bracket 120 are slidably matched. The first elastic member 130 is connected between the first bracket 110 and the second bracket 120, and the first elastic member 130 elastically pushes the first bracket 110 and the second bracket 120 away from each other. In this way, the first bracket 110 and the second bracket 120 penetrated in the cleaning member 21 are propped apart in a direction away from each other by the first elastic member 130, so that the cleaning member 21 is kept in a roughly flat state. It can be understood that the support assembly 22 mentioned below is also used to drive the cleaning member 21 to rotate, so the first elastic member 130 is used to increase the closeness of the direct contact between the cleaning member 21 and the support assembly 22, so that the support assembly 22 drives the cleaning member 21 to rotate.

[0057] Furthermore, since the first bracket 110 and the second bracket 120 can slide relative to each other, the first elastic member 130 can be elastically compressed to drive the first bracket 110 and the second bracket 120 to move toward each other. In this way, the support frame 100 can be in a retracted state, so that the support frame 100 can be installed in the cleaning member 21.

[0058] In one embodiment, the first elastic member 130 is a compression spring, and two ends of the first elastic member 130 elastically abut against the first bracket 110 and the second bracket 120 respectively.

[0059] See also Figure 3 In one embodiment, one of the first bracket 110 and the second bracket 120 is provided with a slot 111 facing the other, and the other passes through the slot 111 and slides with the slot wall of the slot 111. Therefore, the slot 111 can limit and guide the sliding cooperation between the first bracket 110 and the second bracket 120 to a certain extent, so that the positions of the two are stable when they move relative to each other.

[0060] Please continue reading Figure 3 In one embodiment, the first elastic member 130 is inserted into the slot 111, and the slot wall of the slot 111 can be recessed to form a first limiting portion 112 adapted to the shape of the first elastic member 130, and the first elastic member 130 is inserted into the slot 111 at a limiting portion 112. In this way, the first elastic member 130 can be limited by the first limiting portion 112, so that the first elastic member 130 can stably elastically abut between the first bracket 110 and the second bracket 120. The first limiting portion 112 can be specifically a shaft hole-shaped structure.

[0061] In one embodiment, the slot 111 may be provided on the first bracket 110 and face the second bracket 120. A cavity (not shown in the figure, the same below) is provided in the second bracket 120, and the first elastic member 130 is provided in the slot 111 and the space of the second bracket 120. In this embodiment, the above-mentioned cavity may also be recessed to form a second limiting portion (not shown in the figure, the same below) adapted to the shape of the first elastic member 130, and the first limiting portion 112 cooperates with the second limiting portion to limit the first elastic member 130, so that the first elastic member 130 can be stably elastically abutted between the first bracket 110 and the second bracket 120. At the same time, the above-mentioned space provided on the second bracket 120 can reduce the volume of the second bracket 120, so as to reduce the weight of the second bracket 120 and facilitate assembly. The second limiting portion may also be an axial hole-shaped structure.

[0062] Please continue reading Figure 3 In one embodiment, a portion of the first bracket 110 corresponding to the first limiting portion 112 is raised to form a third limiting portion 113, and a portion of the second bracket 120 corresponding to the second limiting portion is raised to form a fourth limiting portion 121. In this way, the wall thickness of the first bracket 110 and the second bracket 120 can be uniform, thereby ensuring the structural strength of the first bracket 110 and the second bracket 120.

[0063] The first limiting portion 112 and the fourth limiting portion 121 are slidably matched to limit and guide the relative movement of the first bracket 110 and the second bracket 120. It can be understood that the first limiting portion 112 is recessed and formed on the slot wall of the slot 111, the fourth limiting portion 121 is raised and arranged outside the second bracket 120, and the second bracket 120 is inserted into the slot 111 and slidably matched with the slot 111, so the relative movement of the first bracket 110 and the second bracket 120 can be limited and guided by setting the first limiting portion 112 and the fourth limiting portion 121 to slide and match.

[0064] It should be noted that, on the first bracket 110, the first limiting portion 112 corresponds to the position of the third limiting portion 113; on the second bracket 120, the position of the second limiting portion corresponds to the fourth limiting portion 121. Since the first limiting portion 112 and the second limiting portion are aligned with each other, the position of the first limiting portion 112 and the position of the fourth limiting portion 121 can naturally correspond to each other. In the present application, by setting the fourth limiting portion 121, not only can the wall thickness of the second bracket 120 be uniform, but also the movement of the first bracket 110 and the second bracket 120 can be guided and limited.

[0065] The above embodiment is described by taking the slot 111 being disposed on the first bracket 110 as an example. It should be understood that the same is true when the slot 111 is disposed on the second bracket 120 , so it will not be described in detail.

[0066] Please continue reading Figure 3 In one embodiment, the support frame 100 is provided with a limiting hole 125, and the support frame 100 includes a limiting column 115 penetrating the limiting hole 125, and the limiting hole 125 extends along the direction of relative movement between the first bracket 110 and the second bracket 120. The limiting column 115 is provided on one of the first bracket 110 and the second bracket 120, and the limiting hole 125 is provided on the other. In this way, the limiting column 115 can respectively abut against the two opposite sides of the limiting hole 125 in the relative movement direction between the first bracket 110 and the second bracket 120, so that the relative movement between the first bracket 110 and the second bracket 120 is within a preset range.

[0067] Specifically, the limiting column 115 is disposed on the first bracket 110, and the limiting hole 125 is opened on the second bracket 120. The limiting hole 125 is a bar-shaped hole.

[0068] Of course, the limiting column 115 may also be disposed on the second bracket 120 , and correspondingly, the limiting hole 125 is opened on the first bracket 110 .

[0069] See also Figures 4 to 6 In one embodiment, the first button 200 can be driven to move through the first bracket 110 to a first unlocking position and a first locking position. It can be understood that the driving force of the first button 200 is the driving force provided to the first button 200 by the user during disassembly.

[0070] The second bracket 120 is provided with a first buckle 122. When the second bracket 120 is forced to move in a direction close to the first bracket 110, the first buckle 122 can be engaged with the first button 200 in the first locking position; when the first button 200 is forced to move to the first unlocking position, it is separated from the first buckle 122. It is easy to understand that when the support frame 100 needs to be retracted, a driving force can be provided to the second bracket 120 or the first bracket 110, so that the second bracket 120 and the first bracket 110 move in a direction close to each other and are in a retracted state.

[0071] Relative to the first bracket 110, the movement direction of the first button 200 is perpendicular to the movement direction of the second bracket 120, so the relative movement of the first bracket 110 and the second bracket 120 will not drive the first button 200 to move relative to the first bracket 110. Figures 5 to 9 The movement direction of the first button 200 relative to the first bracket 110 is shown in Figure 5 , Figure 6 The middle label is M.

[0072] In this embodiment, when the second bracket 120 moves toward the direction close to the first bracket 110, the first buckle 122 is engaged with the first button 200, so that the second bracket 120 and the first bracket 110 can be kept at a relatively close distance. In this way, it is convenient to insert the support frame 100 into the cleaning member 21. When the first button 200 moves to the first unlocking position, the first button 200 is separated from the first buckle 122, so the first bracket 110 and the second bracket 120 move away from each other under the action of the first elastic member 130 to open the cleaning member 21. In other words, in the support assembly 22 provided by the present invention, the first button 200 is not only used to plug and unplug the support frame 100 from the housing 10, but the first button 200 can also unlock and lock the first bracket 110 and the second bracket 120. In this way, the overall structure of the support assembly 22 is simpler and more compact.

[0073] Please continue reading Figures 5 to 7In one embodiment, the first bracket 110 is provided with a first receiving groove 114, and the first button 200 includes a first sliding portion 210. The first sliding portion 210 at least partially penetrates the first receiving groove 114 and slides with the groove wall of the first receiving groove 114. Therefore, the movement direction of the first sliding portion 210 can be limited by the first receiving groove 114, that is, the movement direction of the first button 200 as a whole is limited, so that the first button 200 can only move between the first unlocking position and the first locking position along a preset direction. The extension direction of the first receiving groove 114 is perpendicular to the movement direction of the second bracket 120 relative to the first bracket 110. In this way, the groove wall of the first receiving groove 114 abuts against the first sliding portion 210, which can reduce the influence of the relative movement of the first bracket 110 and the second bracket 120 on the first button 200, that is, improve the stability of the mutual engagement between the first button 200 and the first buckle 122.

[0074] Please continue reading Figures 5 to 7 In one embodiment, the first bracket 110 further includes a first clamping portion 220 connected to the first sliding portion 210. A clamping groove 123 is provided on the second bracket 120, and the first clamping portion 220 at least partially penetrates the clamping groove 123 and slides with the groove wall of the clamping groove 123. The first buckle 122 is provided in the clamping groove 123, and the first buckle 122 can be clamped with the first clamping portion 220 when it is in the first locking position. In this embodiment, by providing the first clamping portion 220 and the clamping groove 123, even when the first bracket 110 and the second bracket 120 are relatively open, the first button 200 is directly connected and matched with the second bracket 120, so that the clamping force of the first button 200 and the housing 10 can act on the first bracket 110 and the second bracket 120 in a more balanced manner, so that the first bracket 110 and the second bracket 120 can have a stable relative position relative to the housing 10 through the first button 200. Furthermore, such a configuration also facilitates the first button 200 to simultaneously drive the first bracket 110 and the second bracket 120 to separate from the housing 10. In addition, the first clamping portion 220 is accommodated by the clamping groove 123, and the groove wall of the clamping groove 123 and the first clamping portion 220 are slidably matched to guide and limit the relative movement between the second bracket 120 and the first button 200, so that the first button 200 and the first buckle 122 can be more accurately aligned and clamped, avoiding interference caused by unstable relative movement.

[0075] Please continue reading Figures 5 to 7 In one embodiment, the first clamping portion 220 can be hollow, and when the first bracket 110 and the second bracket 120 move toward each other, the first buckle 122 can extend into the first clamping portion 220 and clamp with the first clamping portion 220.

[0076] Specifically, the first clamping portion 220 is provided with a first clamping interface 221 facing the first clamping buckle 122, and the first clamping portion 220 is provided with a first abutting surface 222 facing the inside of the first clamping portion 220. The first clamping buckle 122 is provided with a first inclined surface 122a on one side close to the first button 200, and the side wall of the first clamping interface 221 includes a second inclined surface 221a. Figure 5 When the second bracket 120 moves toward the direction close to the first bracket 110, the first inclined surface 122a will push the second inclined surface 221a, so that the first button 200 moves toward the first unlocking position, so as to retract to the position where the first card interface 221 and the first buckle 122 are aligned and the first buckle 122 passes through. When the first clamping portion 220 passes through the first card interface 221 and separates from the side wall of the first card interface 221, the second elastic member 300 mentioned below will push the first button 200 to move toward the first locking direction. In this way, the first buckle 122 can pass through the first card interface 221 and extend into the interior of the first clamping portion 220 to abut against the first abutting surface 222, thereby completing the clamping of the first buckle 122 and the first button 200.

[0077] Combination Figure 6 When the first button 200 moves from the first locking position to the first unlocking position, the first buckle 122 is separated from the first abutting surface 222, and the first buckle 122 is withdrawn from the first card interface 221 to the outside of the first button 200. In this way, the first buckle 122 is separated from the first button 200. At this time, since the first buckle 122 loses the engagement with the first button 200, the first elastic member 130 pushes the first bracket 110 and the second bracket 120 to move away from each other to open the cleaning member 21.

[0078] Please continue reading Figures 5 to 7 In one embodiment, the support assembly 22 further includes a second elastic member 300, which is connected between the first button 200 and the support frame 100. The second elastic member 300 provides elastic force to the first button 200 so as to push the first button 200 to move toward the first locking position. Moreover, under the action of the second elastic member 300, the first button 200 can also be kept in the first locking position. With such a configuration, on the one hand, the first button 200 can be kept in an extended state so as to be plugged with the housing 10. On the other hand, the first button 200 can be kept in the first locking position by the second elastic member 300 so as to be kept in the first locking position so as to be kept in the first snap 122.

[0079] Specifically, the second elastic member 300 may be disposed in the first receiving groove 114, and two ends of the second elastic member 300 respectively abut against the first sliding portion 210 and the bottom wall of the first receiving groove 114. The second elastic member 300 may specifically be a compression spring.

[0080] Please continue reading Figures 5 to 7 In one embodiment, a first position-limiting body 211 is protruded from the first button 200, and a first through hole 114a for accommodating the first position-limiting body 211 is provided on the first bracket 110. When the first button 200 is in the first unlocking position and the first locking position, the first position-limiting body 211 abuts against the two side walls opposite to the first through hole 114a. Thus, the movement of the first position-limiting body 211 can be limited by the first through hole 114a, that is, the movement of the first button 200 can be limited between the first unlocking position and the first locking position by the first through hole 114a.

[0081] Specifically, the first limiting body 211 may be protruded from the first sliding portion 210 , and the first through hole 114 a is formed on the side wall of the first receiving groove 114 .

[0082] See also Figures 8 to 10 In one embodiment, the support assembly 22 includes a second button 400. The support frame 100 includes a second buckle 124, the second buckle 124 is provided on one of the first bracket 110 and the second bracket 120, and the second button 400 is provided on the other. The second button 400 is subjected to force to engage or separate the second button with the second buckle 124, that is, by actively providing a driving force to the second button 400, the second button 400 can be engaged or separated with the second buckle 124. In this way, by engaging the first button 200 with the first buckle 122, and engaging the second button 400 with the second buckle 124, both ends of the first bracket 110 and the second bracket 120 can be engaged with each other, so that the support frame 100 can be stably maintained in a retracted state, and it is convenient to insert the cleaning member 21. It is understandable that in order to ensure the mopping range, the first bracket 110 and the second bracket 120 are usually in the shape of long strips, so in this embodiment, they are arranged in this way so that both ends of the first support frame 100 and the second support frame 100 can maintain a stable clamping connection.

[0083] Combination Figure 8, the second buckle 124 can be engaged with the second button 400 in the second locking position. The second button 400 can be hollow, and a second card interface 410 communicating with the interior is provided on a side of the second button 400 close to the second buckle 124, and a second abutting surface 420 facing the interior is provided in the second button 400. A third inclined surface 124a is provided on a side of the second buckle 124 close to the second button 400, and a fourth inclined surface 411 is provided on the side wall of the second card interface 410. When the second bracket 120 moves in a direction close to the first bracket 110, the third inclined surface 124a will push the fourth inclined surface 411, so that the second button 400 moves in the direction of the second unlocking position, so as to retract to a position where the second card interface 410 and the second buckle 124 are aligned. When the second buckle 124 passes through the second card interface 410 and separates from the side wall of the second card interface 410, the third elastic member 500 mentioned below will push the second button 400 to move in the second locking direction. In this way, the second buckle 124 can pass through the second card interface 410 and extend into the second button 400 to abut against the second abutting surface 420. Thus, the second buckle 124 and the second button 400 are connected.

[0084] Combination Fig. 9 When the second button 400 moves from the second locking position to the first unlocking position, the second buckle 124 is separated from the second abutting surface 420, and the second buckle 124 corresponds to the second card interface 410, and the second buckle 124 can be withdrawn from the second card interface 410 to the outside of the second button 400. At this time, due to the loss of the clamping effect between the second buckle 124 and the second button 400, the first bracket 110 and the second bracket 120 will move away from each other under the push of the first elastic member 130 to open the cleaning member 21.

[0085] Please refer again Figure 3 In one embodiment, the number of the first elastic members 130 can be multiple, and the multiple first elastic members 130 are spaced apart along the length direction of the first support frame 100. In this way, when the first buckle 122 and the second buckle 124 are separated from the first button 200 and the second button 400 respectively, the multiple first elastic members 130 can simultaneously push the first support frame 110 and the second support frame 120 to move away from each other, so that all regions of the first support frame 110 and the second support frame 120 in the length direction move away from each other to evenly open the cleaning member 21.

[0086] Please continue reading Figures 8 to 10In one embodiment, the second button 400 is retractably arranged on the support frame 100 and is used to be plugged in or separated from the housing 10. The support assembly 22 also includes a third elastic member 500, which is connected between the second button 400 and the support frame 10. The third elastic member 500 provides elastic force to the second button 400 so as to push the second button 400 toward the position where the second button 400 is plugged in with the housing 10, that is, the second button 400 can move in the direction of plugging in with the housing 10 under the drive of the third elastic member 500. It can be understood that, as mentioned above, the second button 400 can be used to unlock and lock one end of the support frame 100. Since this unlocking process needs to be achieved by pressing the second button 400, the second button 400 is usually set to protrude from the support frame 100. In this embodiment, by setting the second button 400 to also be plugged in with the housing 10, the protruding second button 400 can be fully utilized to improve the stability of the plug-in installation of the support assembly 100. The third elastic member 500 elastically abuts against the second button 400 to extend, so that the second button 400 can remain extended and plugged into the housing 10 .

[0087] The second button 400 may be specifically movably disposed on the first bracket 110 , and correspondingly, the second buckle 124 is disposed on the second bracket 120 .

[0088] Of course, the second button 400 may also be movably disposed on the second bracket 120 , and correspondingly, the second buckle 124 is disposed on the first bracket 110 .

[0089] Please continue reading Figure 8 and Fig.11 The first bracket 110 is provided with a second receiving groove 116, and the second button 400 is retractably disposed in the second receiving groove 116. The two ends of the third elastic member 500 are respectively in contact with the second button 400 and the bottom wall of the second receiving groove 116. The second button 400 is provided with a second limiting body 430 protruding therefrom, and the groove wall of the second receiving groove 116 is provided with a second through hole (not shown in the figure, the same below), and the second limiting body 430 is provided with the second through hole to limit the movement range of the second button 400.

[0090] Please continue reading Figure 3In one embodiment, the support assembly 22 further includes a rotating shaft 600 and a supporting body 700. The rotating shaft 600 is used to abut against the cleaning member 21. When the rotating shaft 600 rotates, it is used to drive the cleaning member 21 to rotate together, so as to improve the wiping effect of the cleaning member 21. The two ends of the rotating shaft 600 are respectively rotatably connected to the support frame 100, and the support frame 100 can support the rotation movement of the rotating shaft 600. The supporting body 700 is arranged on the support frame 100 to be rotatable under force and corresponds to the area between the two ends of the supporting shaft 600. Since the rotating shaft 600 usually has a large length span in the axial direction, by arranging the supporting body 700 to support the area between the two ends of the rotating shaft 600, the radial runout of the rotating shaft 600 during the rotation process can be reduced, so that the rotating shaft 600 can rotate more smoothly.

[0091] See also Figure 3 Combined with Fig.11 In one embodiment, the rotating shaft 600 includes a driving shaft 610 and a driven shaft 620, and the driving shaft 610 and the driven shaft 620 are respectively arranged on opposite sides of the support frame 100, and the driving shaft 610 and the driven shaft 620 are distributed along the direction of relative movement between the first bracket 110 and the second bracket 120. That is to say, along the direction of relative movement between the first bracket 110 and the second bracket 120, the driving shaft 610 and the driven shaft 620 are located at the outermost side of the support frame 100, that is, when the support frame 100 is opened, the driving shaft 610 and the driven shaft 620 are both used to push the cleaning member 21 to make the cleaning member 21 unfold. That is to say, in this embodiment, the first bracket 110 and the second bracket 120 are in contact with the cleaning member 21 through the driving shaft 610 and the driven shaft 620 respectively. It can be understood that the first elastic member 130 can make the driving shaft 610 and the driven shaft 620 contact more closely, so that the cleaning member 21 can move accordingly with the rotation of the driving shaft 610 .

[0092] In one embodiment, the driving shaft 610 is used to be connected to a driver so as to rotate under the driving action of the driver, thereby driving the cleaning member 21 to move accordingly.

[0093] In one embodiment, the driving shaft 610 and the driven shaft 620 have corresponding support bodies 700 , and at least two support bodies 700 respectively support the driving shaft 610 and the driven shaft 620 to support the reaction force applied by the cleaning member 21 to the driving shaft 610 and the transmission shaft.

[0094] In one embodiment, the driving shaft 610 may be rotatably connected to the second bracket 120 , and correspondingly, the driven shaft 620 may be rotatably connected to the first bracket 110 .

[0095] Of course, the driving shaft 610 can also be rotatably connected to the first bracket 110 , and correspondingly, the driven shaft 620 can be rotatably connected to the second bracket 120 .

[0096] See also Fig.11 In one embodiment, the support body 700 includes a plurality of support wheels 710, and two support wheels 710 are respectively located on both sides of the rotation direction of the rotating shaft 600. In the circumferential direction of the rotating shaft 600, both support wheels 710 are in rolling cooperation with the rotating shaft 600. In this way, the support wheels 710 can reduce the obstruction to the movement of the rotating shaft 600 by rolling cooperation. And the two support wheels 710 are respectively located on both sides of the rotation direction of the rotating shaft 600, so no matter whether the rotating shaft 600 rotates forward or reverse, there is always a corresponding support wheel 710 to support the rotating shaft 600.

[0097] Furthermore, the support wheels 710 are arranged in groups of two, and the support body 700 includes at least two groups of support wheels 710 to respectively support the two sides of the driving shaft 610 in the rotation direction and the two sides of the driven shaft 620 in the rotation direction.

[0098] Example 2

[0099] This embodiment provides a cleaning device, such as Figure 2 As shown, the cleaning device 20 includes a support assembly 22 and a cleaning member 21, and the cleaning member 21 is sleeved outside the support assembly 22. When the first bracket 110 and the second bracket 120 move in a direction away from each other, the cleaning member 21 can be spread apart, and the cleaning member 21 can be detachably mounted on the housing 10 through the support assembly 22. Since the cleaning device 20 in this embodiment adopts all the technical solutions of the above embodiment 1, it also has all the beneficial effects brought by the technical solutions of the above embodiment 1.

[0100] Example 3

[0101] This embodiment provides a cleaning device, such as Fig.12 As shown, the cleaning device 1 includes a cleaning device 20 and a housing 10, and the cleaning device 20 is detachably mounted on the housing 10. Since the cleaning device 20 in this embodiment adopts all the technical solutions of the above-mentioned embodiments 1 and 2, it also has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments 1 and 2.

[0102] See also Fig.13 and Fig.14In one embodiment, the housing 10 is provided with a first jack 12 that is plugged and matched with the first button 200. The hole wall of the first jack 12 includes an abutting wall 13, which abuts the first button 200 in a direction opposite to the separation direction of the support assembly 22 and the housing 10. A notch 12a is provided in a part of the abutting wall 13. The notch 12a can avoid the action of pressing and toggling the first button 200. In short, the abutting wall 13 abuts the first button 200 in a direction opposite to the separation direction of the support assembly 22 and the housing 10, that is, the housing 10 mainly limits the first button 200 through the abutting wall 13. When the cleaning device 20 needs to be disassembled, the first button 200 can be moved from the first locked position to the first unlocked position by passing a finger through the first jack 12 to continuously press the first button 200. Since the notch 12a is provided on the housing 10, the finger can be moved out of the first jack 12 from the notch 12a. With such arrangement, during the disassembly process of the cleaning device 20 , the finger can continuously provide force to the first button 200 to keep it in the first unlocked position, thereby facilitating the disassembly and assembly of the cleaning device 20 .

[0103] See also Figure 7 and Fig.14 In one embodiment, a first button 200 is provided with an inclined introduction surface 230 on one side facing the housing 10. When the first button 200 moves toward the housing 10, the housing 10 will push the introduction surface 230 to make the first button 200 retreat to the first unlocking position and pass over the abutting wall 13. When the first button 200 is aligned with the first plug hole 12, the introduction surface 230 loses the abutting effect of the housing 10, and under the action of the second elastic member 300, the first button 200 will move to the first locking position to be inserted into the first plug hole 12. During the installation of the cleaning device 20, it is only necessary to press the cleaning member 21 assembly downward toward the housing 10, which is convenient for installation.

[0104] Please continue reading Figures 13 to 16 In one embodiment, the first bracket 110 is provided with a first support portion 117 and a second support portion 118 respectively rotatably connected to the two ends of the driven shaft 620, and the second bracket 120 is provided with a third support portion 126 and a fourth support portion 127 respectively rotatably connected to the two ends of the driving shaft 610. The first support portion 117 and the third support portion 126 are provided at the same end of the support frame 100, and the second support portion 118 and the fourth support portion 127 are located at the other end of the support frame 100.

[0105] As mentioned above, the housing 10 is provided with a mounting slot 11, and the first insertion hole 12 is provided on one side of the slot wall of the mounting slot 11. The slot wall of the mounting slot 11 is also provided with a first matching hole 15, a second matching hole 16, a third matching hole 17 and a fourth matching hole 18. The first insertion hole 12, the first matching hole 15 and the third matching hole 17 are located on the same side of the slot wall of the mounting slot 11; the second matching hole 16, the fourth matching hole 18 and the second insertion hole 14 mentioned below are located on the other side of the slot wall opposite to the mounting slot 11. The first supporting portion 117 is provided with the first matching hole 15, the second supporting portion 118 is provided with the second matching hole 16, the third supporting portion 126 is provided with the third matching hole 17 and the fourth supporting portion 127 is provided with the fourth matching hole 18. It can be understood that since each supporting portion corresponds to a different end of the rotating shaft 600, the rotating shaft 600 can be better supported to rotate stably by correspondingly supporting the positions of each supporting portion through each matching hole.

[0106] See also Fig.14 In one embodiment, a first avoidance opening 15 a is opened on the hole wall of the first matching hole 15 to form a semi-open hole structure, so that the first supporting portion 117 can be directly installed into the first matching hole 15 .

[0107] Similarly, a third avoidance opening 17 a is formed on the hole wall of the third matching hole 17 to form a semi-open hole structure, so that the third supporting portion 126 can be directly installed into the third matching hole 17 .

[0108] The first avoidance opening 15a is opened along the direction in which the support assembly 22 is away from the housing 10; the third avoidance opening 17a is opened along the direction in which the support assembly 22 is away from the housing 10. In this way, when the support assembly 22 is away from and inserted into the installation slot 11, the hole wall of the first matching hole 15 and the hole wall of the second matching hole 16 will not interfere with the movement of the support assembly 22. Therefore, the support frame 100 is allowed to control the relative position of the support assembly 22 and the housing 10 only through the first button 200, making the disassembly and assembly of the support assembly 22 more convenient.

[0109] See also Fig.14 In one embodiment, the central angle of the circumferential surface where the hole wall of the first matching hole 15 contacts the first supporting portion 117 is the first supporting angle. The first supporting angle is not less than 90° to improve the supporting effect of the hole wall of the first matching hole 15 on the first supporting portion 117 in the circumferential direction. The first supporting angle can be 120°, 150°, 180°, etc.

[0110] Similarly, see Fig.14In one embodiment, the central angle of the circumferential surface where the wall of the third matching hole 17 and the third supporting portion 126 contact is the second supporting angle. The second supporting angle is not less than 90° to improve the supporting effect of the wall of the third matching hole 17 on the third supporting portion 126 in the circumferential direction. The second supporting angle can be 120°, 150°, 180°, etc.

[0111] See also Fig.16 In one embodiment, the second matching hole 16 abuts against the second support portion 118 at all locations in the circumferential direction to stably support the second support portion 118. The fourth matching hole 18 abuts against the fourth support portion 127 at all locations in the circumferential direction to stably support the fourth support portion 127.

[0112] Of course, the second matching hole 16 and the fourth matching hole 18 can also be designed to be semi-open, so as to facilitate the connection between the rotating shaft 600 and the driver. For example, a fourth avoidance opening 18a can be opened on the hole wall of the fourth matching hole 18, so as to facilitate the connection between the rotating shaft 600 and the driver, so as to drive the rotating shaft 600 to rotate and drive the cleaning member 21 to move.

[0113] See also Fig.16 In one embodiment, the housing 10 is further provided with a second insertion hole 14, and the second button 400 is telescopically disposed through the second insertion hole 14. The second insertion hole 14 can abut against the second button 400 at any position in the circumferential direction to stably support the support frame 100.

[0114] Obviously, the embodiments described above are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, ordinary technicians in this field can make other different forms of changes or modifications without creative work, which should fall within the scope of protection of the present invention.
