Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a floor brush module, cleaning equipment, and cleaning system. Background Technology

[0002] Cleaning equipment refers to various mechanical devices and tools used for cleaning, maintaining, and improving the environment. They are widely used in cleaning homes, commercial premises, industrial facilities, and public places. Existing cleaning equipment includes carpet cleaners and floor scrubbers. In practical use, there are several ways to assemble and disassemble the roller brushes of cleaning equipment.

[0003] For example, it can be pulled out along its axis. In this case, the cleaning equipment is usually equipped with a spring-loaded mechanism. After pressing the spring-loaded mechanism with external force, a portion of the roller brush pops out, but the user still needs to manually pull it out with considerable external force afterward. The same applies to the installation process, which makes disassembly and assembly inconvenient.

[0004] Alternatively, an openable cover could be installed on top of the cleaning equipment base. When the cover is opened, the roller brush can be removed or installed through the opening. Typically, the cleaning equipment includes a mounting mechanism to assemble the roller brush into the base. However, current technologies generally aim to simplify the mounting mechanism's structure to make the roller brush assembly and disassembly easier; conversely, they may aim to increase the structural complexity of the mounting mechanism to improve its ability to limit the roller brush's position after installation. This results in a trade-off between simplifying assembly and disassembly and enhancing the limiting effect. Utility Model Content

[0005] The main purpose of this utility model is to propose a floor brush module, cleaning equipment and cleaning system, which aims to solve the problem that the simplification of the disassembly and assembly of the roller brush and the enhancement of the limiting function are mutually exclusive in traditional cleaning equipment.

[0006] To achieve the above objectives, this utility model proposes a floor brush module for use in cleaning equipment, comprising:

[0018] Optionally, the bottom shell is provided with a snap hole communicating with the mounting cavity;

[0019] The locking component includes a locking body and a latching portion disposed on the locking body. The locking body is elastically and movably mounted on the pressing component.

[0036] In addition, to achieve the above objectives, this utility model also provides a floor brush module for use in cleaning equipment, comprising:

[0037] The base includes a bottom shell and a cover shell, wherein the bottom shell forms a mounting cavity and the cover shell is movably disposed on the bottom shell;

[0041] Optionally, a limiting distance is formed between the pressing member and the bottom shell, and the width of the bushing in the same direction is the pressing width;

[0042] When the pressing member moves in a direction away from the bottom shell until the minimum value of the limiting distance is not less than the pressing width, the retaining structure maintains the posture of the pressing member unchanged.

[0043] Optionally, the bottom shell defines a mounting area for accommodating the bushing;

[0044] The pressing member is rotatably disposed relative to the bottom shell, and forms a first orthographic projection area on the bottom shell during rotation.

[0045] Optionally, the bottom shell also defines a receiving cavity on the side of the mounting cavity, and a portion of the pressing member extends into the receiving cavity;

[0046] The retaining structure is housed within the receiving cavity and is connected to the portion of the pressing member that extends into the receiving cavity.

[0047] Optionally, the pressing member is rotatably disposed relative to the bottom shell;

[0048] The retaining structure is disposed at the rotatable connection between the pressing member and the bottom shell.

[0049] In addition, to achieve the above objectives, this utility model also provides a cleaning device, including a body and a floor brush module as described above.

[0050] In addition, to achieve the above objectives, this utility model also provides a cleaning system, including a base station or base, and the cleaning equipment described above.

[0051] In the technical solution provided by this utility model, by rotating the pressing member away from the bottom shell, the area inside the bottom shell where the roller brush assembly is assembled is exposed, thus ensuring that the roller brush assembly can be installed into the bottom shell smoothly and without obstruction. Then, by rotating the pressing member closer to the bottom shell, the bushing in the roller brush assembly can be pressed against the bottom shell. At this time, the pressing member and the bottom shell can jointly limit the bushing axially and radially, preventing the bushing from detaching from the bottom shell, but without affecting the rotation of the brush body relative to the bushing. This application only requires rotating the pressing member to achieve flexible switching between pressing and releasing states of the roller brush assembly, without applying excessive external force or complicated operations, thus simplifying the assembly and disassembly process of the roller brush assembly. Furthermore, after the roller brush assembly is installed into the bottom shell, the pressing member can directly limit the roller brush assembly axially and radially, sufficiently ensuring the stable installation and smooth operation of the roller brush assembly. Furthermore, the limiting strength of the pressing component on the roller brush assembly does not significantly increase the difficulty of disassembling and assembling the roller brush assembly, ultimately helping to improve the reliability of the roller brush assembly.

[0069] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0070] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0071] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0072] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0073] Please see Figures 1 to 14 This utility model provides a floor brush module and the cleaning equipment and cleaning system that can be applied to it.

[0074] It should be noted that, for ease of understanding, the following explanation will specifically use the floor brush module and its applicable cleaning equipment and systems as examples, illustrating the corresponding forward / backward, left / right, and up / down directions. These directions are generally perpendicular to each other. The forward direction typically corresponds to the direction the product primarily faces the user. For mobile cleaning equipment, the forward direction generally corresponds to the equipment's forward movement.

[0075] In view of the above, cleaning equipment may include, but is not limited to, sweepers, floor scrubbers, carpet cleaners, etc.

[0076] Cleaning equipment can be used as a standalone product. Alternatively, it can be integrated into a cleaning system as a component within that system.

[0077] At this point, the cleaning system may also include a base station or a docking station. The cleaning equipment has a working state where it can operate independently of the base station or docking station and move around. Furthermore, the cleaning equipment also has an idle state where it can be docked with the base station or docking station. When in the idle state, the base station or docking station can perform preset operations on the cleaning equipment as needed.

[0078] Generally, the base is designed to at least partially house the cleaning equipment. That is, the base may have a pre-installed storage slot. The opening of the storage slot is typically forward-facing. This allows the cleaning equipment to move directly into the storage slot via its opening when it is not in use. This significantly reduces the overall space occupied by the cleaning system when not in use.

[0079] Of course, the base station can also perform functions similar to those of the aforementioned base, such as storage. In addition, the base station can integrate functions such as cleaning, charging, and dust collection. Correspondingly, the base station can be equipped with a cleaning module to clean cleaning equipment when it is idle. The base station can also be equipped with a vacuuming module to collect dirt collected from cleaning equipment when it is idle. The base station can also be equipped with a charging module to charge cleaning equipment when it is idle. And so on, without limitation.

[0080] Since this design primarily focuses on improving the floor brush module, the following will combine... Figures 1 to 14 The structure of the floor brush module will be described in detail.

[0081] The floor brush module includes a base 100, a roller brush assembly 200, and a pressing component 300.

[0082] The base 100 includes a bottom shell 110 and a cover shell. The bottom shell 110 forms a mounting cavity 111. The cover shell is movably disposed on the bottom shell 110.

[0083] The roller brush assembly 200 is disposed within the mounting cavity 111. The roller brush assembly 200 includes a brush body 210 and a bushing 220 disposed at least at one end of the brush body 210. The brush body 210 is rotatably mounted on the bushing 220 about its own axis. The bushing 220 is disposed in the base shell 110.

[0084] The pressing component 300 is disposed within the mounting cavity 111 and is movable in the direction of approaching and away from the bottom shell 110.

[0085] After moving into position towards the bottom shell 110, the pressing member 300 presses the bushing 220 against the bottom shell 110 and limits the bushing 220. After moving into position in the direction opposite to the bottom shell 110, the pressing member 300 releases the limit on the bushing 220, allowing the roller brush assembly 200 to be removed from the mounting cavity 111.

[0086] In the technical solution provided by this utility model, by manipulating the pressing member 300 to move away from the bottom shell 110, the area where the roller brush assembly 200 is assembled inside the bottom shell 110 is exposed, thereby ensuring that the roller brush assembly 200 can be installed into the bottom shell 110 smoothly and without obstruction. Then, by manipulating the pressing member 300 to move closer to the bottom shell 110, the bushing 220 in the roller brush assembly 200 can be pressed against the bottom shell 110. At this time, the pressing member 300 and the bottom shell 110 can jointly limit the bushing 220, so that the bushing 220 cannot be disengaged from the bottom shell 110, but it does not affect the rotation of the brush body 210 relative to the bushing 220 at all.

[0087] This application allows for flexible switching between pressing and releasing states of the roller brush assembly 200 by simply rotating the pressing component 300. No excessive external force is required, and there are no complicated operating actions. This simplifies the assembly and disassembly process of the roller brush assembly 200.

[0088] After the roller brush assembly 200 is installed into the base shell 110, the pressing component 300 can directly limit the axial and radial positions of the roller brush assembly 200, which is sufficient to ensure the stable installation and smooth operation of the roller brush assembly 200. Moreover, the limiting strength of the pressing component 300 on the roller brush assembly 200 does not significantly increase the difficulty of disassembling and assembling the roller brush assembly 200, ultimately helping to improve the reliability of the roller brush assembly 200.

[0089] Specifically, the mounting cavity 111 may have a first opening 112. The first opening 112 may be oriented upwards and / or forwards. During the movement of the cover, the first opening 112 can be opened or closed. The pressing member 300 is generally also exposed at the first opening 112. This facilitates the user's operation of the pressing member 300 through the first opening 112. Similarly, the entire roller brush assembly 200 is generally exposed at the first opening 112. This allows the user to easily install and remove the roller brush assembly 200 through the first opening 112 after the pressing member 300 moves away from the bottom cover 110.

[0090] It is understood that the base shell 110 generally includes at least a base plate. The base plate is for mounting the roller brush assembly 200. The pressing member 300 can move relative to the base plate, thereby pressing the bushing 220 against the base plate. Based on this, the mounting cavity 111 may also have a second opening 113. The second opening 113 is generally located on the base plate, that is, the second opening 113 faces downward. When assembled, the brush body 210 in the roller brush assembly 200 is at least partially exposed at the second opening 113. In this way, during operation, the brush body 210 can clean the dirt on the surface to be cleaned by its own rotational movement.

[0091] The first opening 112 can be set separately from the second opening 113, structurally presenting as two opening structures. Alternatively, the first opening 112 can be set as an integral part of the second opening 113, structurally presenting as a single, larger opening structure.

[0092] Of course, the base 100 can also be equipped with a suction channel. The suction port of the suction channel is usually set downwards, which makes it convenient to suck the dirt on the surface to be cleaned into the suction channel during operation.

[0093] The suction port of the suction channel can be located on the front, rear, left, or right side of the second opening 113, or directly connected to the second opening 113.

[0094] See Figures 1 to 4 The roller brush assembly 200 is generally elongated in the left-right direction and disposed within the mounting cavity 111. This makes the axial direction of the brush body 210 in the roller brush assembly 200 correspond to the left-right direction. One or at least two brush bodies 210 can be arranged side by side at intervals in the front-back direction.

[0095] The bushing 220 is generally provided at both ends of the brush body 210 along the axial direction. However, it can be understood that the bushings 220 at both ends of the brush body 210 can have the same structure. Alternatively, they can be differentiated according to specific needs.

[0096] When there are at least two brush bodies 210, a bushing 220 at one end can be used to rotate and install only one brush body 210. Alternatively, a bushing 220 at one end can be used to rotate and install at least two brush bodies 210 together.

[0097] To drive the brush body 210 to rotate, the floor brush module generally also includes a drive mechanism. The drive mechanism can be configured arbitrarily according to actual needs. For example, the drive mechanism includes a motor driver and a gear set or other transmission components. The drive mechanism is generally connected to one end of the brush body 210. Based on this, the brush body 210 can be defined to have a drive end 211 close to and connected to the drive mechanism, and a follower end 212 away from the drive mechanism. The drive mechanism is centrally located at the drive end 211 of the brush body 210, occupying the space of the bottom shell 110 corresponding to the drive end 211. At this time, the pressing member 300 can be located at the follower end 212. This ensures that the pressing member 300 and the drive mechanism do not interfere with each other. Furthermore, their spatial arrangement at both ends of the roller brush assembly 200 is more reasonable and balanced.

[0098] The connection between the drive end 211 of the brush body 210 and the drive mechanism is generally a clutch connection. For example, a socket may be provided on the left side of the drive mechanism and / or the base housing 110. The opening of the socket faces, for example, the right side. After the pressing member 300 moves into position away from the base housing 110, the brush body 210 can first be moved to the right to pull the drive end 211 out of the socket, and then removed outward from the first opening 112. Conversely, the brush can first be inserted into the mounting cavity 111 through the first opening 112, then moved to the left to insert the drive end 211 into the socket, and then the pressing member 300 can be moved towards the base plate to press the bushing 220 onto the base plate.

[0099] To avoid hindering the rotational movement of the brush body 210, the outer diameter of the portion of the bushing 220 that is pressed by the pressing member 300 needs to be smaller than the outer diameter of the brush body 210. Specifically, the bushing 220 may include an end cap 221 for rotatably mounting the brush body 210, and a mounting protrusion 222 axially protruding from the end cap 221. The end cap 221 can be directly disposed at the axial end of the brush body 210. Its outer diameter can be adapted to the outer diameter of the adjacent brush body 210. The outer diameter of the mounting protrusion 222 is generally set to be smaller than the outer diameter of the brush body 210.

[0100] For example, the base plate of the bottom shell 110 may partially protrude beside the second opening 113 to form a support boss 120. The support boss 120 and the pressing member 300 have abutting surfaces that are close to each other. For ease of understanding, the abutting surface of the support boss 120 may be specifically named the first abutting surface 121. The abutting surface of the pressing member 300 may be named the second abutting surface 311. The mounting protrusion 222 is fitted between the first abutting surface 121 and the second abutting surface 311. The support boss 120 may raise the mounting height of the mounting protrusion 222 to ensure that the brush body 210 and the base plate are separated, and to avoid interference of the base plate with the rotation of the brush body 210.

[0101] The mounting protrusion 222 and the end cap 221 can be integrally formed. Alternatively, the mounting protrusion 222 and the end cap 221 can be separately formed and then connected in a detachable or non-detachable manner.

[0102] It should be noted that this design does not restrict the movement of the pressing component 300. Depending on actual needs, the pressing component 300 can move translationally towards and away from, for example, the support boss 120. Alternatively, it can... Figures 1 to 14 As shown, the pressing member 300 can be rotatably connected to the bottom shell 110 at one end, and rotate in the direction of approaching and moving away from the support boss 120 at the other end.

[0103] After the pressing member 300 moves into position towards the bottom shell 110 (e.g., the support boss 120), both the pressing member 300 and the support boss 120 together limit the bushing 220. The limiting method is not limited and can be specifically defined according to actual needs. For example, the pressing member 300 and the support boss 120 can at least jointly limit the bushing 220 axially and radially. The specific structure of the support boss 120 and the pressing member 300 can be specifically configured according to the determined limiting method.

[0104] The first abutment surface 121 and the second abutment surface 311 described above can directly clamp and fix the bushing 220. However, to improve assembly stability, in a further embodiment, the first abutment surface 121 and / or the second abutment surface 311 can be provided with limiting grooves. For ease of understanding, the limiting groove provided on the first abutment surface 121 is the first limiting groove 122. The limiting groove provided on the second abutment surface 311 is the second limiting groove 312. The first limiting groove 122 can penetrate the support boss 120 toward the brush body 210 to form a first insertion port. The second limiting groove 312 can penetrate the pressing member 300 toward the brush body 210 to form a second insertion port. The first insertion port and the second insertion port facilitate the formation of a clearance, allowing the assembly protrusion 222 to be inserted into the first limiting groove 122 and / or the second limiting groove 312 in a left-right direction.

[0105] When the first abutment surface 121 opens the first limiting groove 122, the assembly protrusion 222 is inserted into the first limiting groove 122 through the first insertion port. After the pressing member 300 moves into place in the direction of the bottom shell 110, the second abutment surface 311 can cover the opening of the first limiting groove 122, so as to achieve the purpose of the pressing member 300 and the bottom shell 110 jointly clamping the assembly protrusion 222.

[0106] Conversely, when the second abutment surface 311 has a second limiting groove 312, the assembly protrusion 222 can be first placed at the first abutment surface 121. After the pressing member 300 moves into position towards the bottom shell 110, the assembly protrusion 222 enters the first limiting groove 122, and the first abutment surface 121 can cover the opening of the second limiting groove 312, thereby achieving the purpose of the pressing member 300 and the bottom shell 110 jointly clamping the assembly protrusion 222.

[0107] Or such as Figures 1 to 5 As shown, a first limiting groove 122 can be formed on the first abutment surface 121, and a second limiting groove 312 can be formed on the second abutment surface 311. After the pressing member 300 moves into position towards the bottom shell 110, the openings of the first limiting groove 122 and the second limiting groove 312 are aligned, and the first limiting groove 122 and the second limiting groove 312 are engaged, surrounding the periphery of the mounting protrusion 222, so as to achieve the purpose of the pressing member 300 and the bottom shell 110 jointly clamping the mounting protrusion 222.

[0108] As can be understood from the above, the design of both the first limiting groove 122 and the second limiting groove 312 enhances the limiting strength of the pressing component 300 on the roller brush assembly 200 after assembly, without adversely affecting the rotation operation of the pressing component 300. In other words, it does not add any extra burden to the assembly and disassembly of the roller brush assembly 200. This is sufficient to simultaneously achieve the goals of simplifying assembly and disassembly and enhancing limiting.

[0109] Especially when the first abutting surface 121 has a first limiting groove 122 and the second abutting surface 311 has a second limiting groove 312, in order to better align the first limiting groove 122 and the second limiting groove 312, in a further embodiment, one of the two abutting surfaces is provided with a positioning protrusion 123, and the other is provided with a positioning groove 313, with the positioning protrusion 123 and the positioning groove 313 being adapted to each other. For example Figure 3 , Figures 4 to 5 As shown, a positioning protrusion 123 can be provided on the first abutment surface 121, and a positioning groove 313 can be provided on the second abutment surface 311. The positioning protrusion 123 and the positioning groove 313 can be provided in one set or at least two sets. When at least two sets are provided, the positioning protrusion 123 and the positioning groove 313 can be distributed on their respective first abutment surface 121 or second abutment surface 311.

[0110] The pressing part 300 may also have a partial recess on the side facing the brush body 210 to form a first clearance recess 320. The first clearance recess 320 may at least form a clearance space for the end cap 221 in the bushing 220 to be received and housed.

[0111] Based on one or more of the above embodiments, in a further embodiment, the pressing member 300 and the supporting boss 120 can also jointly limit the rotation of the bushing 220. That is, under the combined action of the pressing member 300 and the supporting boss 120, the bushing 220 will not be driven to rotate by the brush body 210.

[0112] Specifically, based on the aforementioned first abutment surface 121 and second abutment surface 311, an anti-rotation structure can be provided on the first abutment surface 121 and / or the second abutment surface 311. The anti-rotation structure is used to limit the rotation of the assembly protrusion 222.

[0113] The anti-rotation structure can be positioned at any location on the first abutment surface 121 and / or the second abutment surface 311. Specifically, when the first abutment surface 121 is provided with a first limiting groove 122 and / or the second abutment surface 311 is provided with a second limiting groove 312 as described above, the anti-rotation structure includes an anti-rotation protrusion 510 and an anti-rotation groove 520. One of the anti-rotation protrusion 510 and the anti-rotation groove 520 is provided on the outer wall of the mounting protrusion 222, and the other is provided on the inner wall of the first limiting groove 122 and / or the second limiting groove 312. After the anti-rotation protrusion 510 and the anti-rotation groove 520 are interlocked, interference is formed in the circumferential direction of the mounting protrusion 222. This interference can prevent the mounting protrusion 222 from rotating relative to the bottom shell 110.

[0114] More specifically, the radial cross-sectional shape of the mounting protrusion 222 can be set to non-circular. The "circular" in "non-circular" generally refers to a perfect circle. A non-circular structure means that at least one anti-rotation protrusion 510 and an anti-rotation groove 520 are formed in the rotational circumference of the mounting protrusion 222. The non-circular shape can be, but is not limited to, polygonal, elliptical, or irregular shapes.

[0115] Correspondingly, each of the two abutting surfaces has a limiting groove. Specifically, the first abutting surface 121 has a first limiting groove 122, and the second abutting surface 311 has a second limiting groove 312. After the pressed part 300 moves into position towards the bottom shell 110, the first limiting groove 122 and the second limiting groove 312 together enclose the periphery of the mounting protrusion 222. The shape of the enclosed area by the first limiting groove 122 and the second limiting groove 312 is suitable for the non-circular shape of the mounting protrusion 222. Correspondingly, this forms an anti-rotation protrusion 510 and an anti-rotation groove 520.

[0116] Specifically, such as Figures 1 to 6 As shown, the aforementioned non-circular shape can be a regular polygon. For example, a regular hexagon. The use of regular polygons makes the structure of the first limiting groove 122, the second limiting groove 312, and the assembly protrusion 222 more regular and aesthetically pleasing, and also helps to balance the forces they bear.

[0117] Furthermore, based on one or more of the above embodiments, in a further embodiment, the floor brush module also includes a locking member 400. The locking member 400 is disposed between the pressing member 300 and the bottom shell 110, and has a locked state and an unlocked state. After the pressing member 300 moves into position towards the bottom shell 110, the locking member 400 switches to the locked state to fix the pressing member 300 to the bottom shell 110. And, after the locking member 400 switches to the unlocked state, the pressing member 300 can move away from the bottom shell 110 under external force, so that the roller brush assembly 200 can be detached from the bottom shell 110. It can be understood that after the locking member 400 switches to the locked state, it can lock the pressing state after the pressing member 300 presses the roller brush assembly 200 to the bottom shell 110, preventing the pressing member 300 from moving in the opposite direction under external force, thus preventing the roller brush assembly 200 from loosening relative to the bottom shell 110. When the locking component 400 is switched to the unlocked state, it does not interfere with or obstruct the pressing component 300. The pressing component 300 can move freely under external force, which helps to quickly remove the roller brush assembly 200.

[0118] The locking member 400 may include a latching portion 420 and a latching hole 130. One of the latching portion 420 and the latching hole 130 is located on the bottom shell 110, and the other is located on the pressing member 300. After the latching portion 420 and the latching hole 130 are engaged with each other, the locking member 400 switches to the locked state. Conversely, after the latching portion 420 and the latching hole 130 are disengaged, the locking member 400 switches to the unlocked state.

[0119] Specifically in an application, such as Figures 5 to 7 As shown, the bottom shell 110 has a latching hole 130 communicating with the mounting cavity 111. The locking member 400 includes a locking body 410 and a latching portion 420 disposed on the locking body 410. The locking body 410 is elastically and movably mounted on the pressing member 300. Under the action of external force, the latching portion 420 is driven by the locking body 410 to move away from the latching hole 130, so as to disengage from the latching hole 130. And when the external force is removed, the latching portion 420 is driven by the locking body 410 to move towards the latching hole 130, so as to engage with the latching hole 130.

[0120] The snap-fit ​​part 420 and the snap-fit ​​hole 130 can be provided at any position of the pressing member 300. For example, when the rear section of the pressing member 300 is rotatably mounted on the bottom shell 110, causing the front section to rotate downward to press against the bushing 220 and to rotate upward to disengage the bushing 220, the snap-fit ​​part 420 can be provided at the front section of the pressing member 300, and is provided on the front end surface and / or the lower end surface of the front section.

[0121] When the pressing component 300 is in the state of pressing the roller brush assembly 200, in order to achieve the locking body 410 being elastically movable in the direction of approaching and moving away from the buckle hole 130:

[0122] In one design, at least a portion of the locking body 410 is made of an elastic material. That is, the locking body 410 can be entirely made of an elastic material, or it can be partially made of an elastic material, or it can have a layer of elastic material attached to it. The elastic deformation capability of the contact elastic material can be compressed when the locking body 410 is moved away from the latch hole 130. When the external force is removed, it recovers its deformation, causing the locking body 410 to move closer to the latch hole 130, thus engaging the latch and the latch hole 130.

[0123] In another embodiment, the floor brush module further includes an elastic element 440 disposed between the locking body 410 and the pressing member 300. The elastic element 440, like the elastic material described above, switches between elastic deformation and elastic reset. The elastic element 440 can be, but is not limited to, a spring, a sheet, a rubber block, etc. The elastic element 440 and the locking body 410, and / or the elastic element 440 and the pressing member 300, can be disassembled and assembled in any suitable manner.

[0124] In addition, the locking member 400 also includes an operating part 430 disposed on the locking body 410. The operating part 430 is used to bear external force. The operating part 430 is generally exposed on the outside of the pressing member 300 and is designed to facilitate manual operation by the user. Specifically, for example, a movable cavity 340 is formed inside the pressing member 300. The movable cavity 340 has a first opening 341 and a second opening 342. The latch is driven to extend and retract at the first opening 341, and the locking member 400 also includes the operating part 430 disposed on the locking body 410. The operating part 430 is exposed at the second opening 342. Specifically, the operating part 430 may partially protrude from the second opening 342 and is designed to facilitate user operation. The operating part 430 moves along the snapping direction of the latch part 420, thereby driving the locking body 410 to move synchronously.

[0125] Next, the pressing member 300 may also have a second recess 330 recessed at a location adjacent to the second opening 342. The second recess 330 forms a force-applying surface. The force-applying surface generally extends and spreads in a direction approximately perpendicular to the fastening direction of the latching part 420, thus facilitating the user to operate the operating part 430 while pressing against the force-applying surface.

[0126] As described above, the locking component 400, at least through the latching part 420, can essentially achieve one-click locking and unlocking of the pressing component 300. This means that when the roller brush assembly 200 needs to be removed, simply triggering the latching part 420 with one click, followed by rotating the pressing component 300 in the opposite direction, will remove the roller brush assembly 200. Conversely, when the roller brush assembly 200 needs to be installed, simply installing the roller brush assembly 200 and then rotating the pressing component 300 in the forward direction will lock the pressing component 300 and limit the pressing of the roller brush assembly 200, further simplifying the assembly and disassembly of the roller brush assembly 200.

[0127] Based on one or more of the above embodiments, in a further embodiment, the floor brush module also includes a retaining structure. The retaining structure is located between the bottom shell 110 and the pressing member 300. After the pressing member 300 moves into position away from the bottom shell 110, the retaining structure maintains the posture of the pressing member 300. When the pressing member 300 moves into position away from the bottom shell 110, that is, when the pressing member 300 has moved at least to a position that ensures the roller brush assembly 200 can be removed, the retaining structure ensures that the pressing member 300 will not fall back towards the bottom shell 110 during the removal of the roller brush assembly 200. This prevents the pressing member 300 from interfering with the removal of the roller brush assembly 200.

[0128] There are several possible solutions for "the pressing component 300 moving into place in a direction away from the bottom shell 110":

[0129] In one embodiment, a limiting gap is formed between the pressing member 300 and the bottom shell 110. Specifically, the limiting gap can be the minimum distance between the first abutment surface 121 and the second abutment surface 311. The width of the bushing 220 in the same direction is the pressing width. The pressing width generally refers to the width of the bushing 220 in the same direction between the first abutment surface 121 and the second abutment surface 311, for example, the width of the aforementioned mounting protrusion 222 in the same direction.

[0130] When the pressing component 300 moves in the direction away from the bottom shell 110 until the minimum value of the limiting distance is not less than the pressing width, it indicates that the pressing component 300 has basically achieved the purpose of "moving into position in the direction away from the bottom shell 110". The holding structure can maintain the posture of the pressing component 300 at this time.

[0131] In this state, the space between the first abutment surface 121 and the second abutment surface 311 is sufficient to allow the mounting protrusion 222 of the bushing 220 to move. The mounting protrusion 222 can move and disengage in any suitable direction. For example, it can be pulled out along the axial direction of the brush body 210. This allows the roller brush assembly 200 to be removed.

[0132] In another embodiment, the base shell 110 is defined to define a placement area for the bushing 220. The pressing member 300 is rotatably disposed relative to the base shell 110. During rotation, a first orthographic projection area is formed at the base shell 110. Then, when the rotation is such that the first orthographic projection area and the placement area are at least partially misaligned, it indicates that the pressing member 300 has essentially achieved the purpose of "moving into position in the direction away from the base shell 110". The retaining structure can maintain the posture of the pressing member 300 at this time.

[0133] Similarly, the first orthographic projection area formed by the pressed part 300 at the bottom shell 110 generally refers to the orthographic projection area formed by the second abutment surface 311 on the first abutment surface 121. Furthermore, it can be further refined to the orthographic projection area formed by the second limiting groove 312 at the first limiting groove 122. Therefore, the placement area corresponding to the first orthographic projection area formed by the second abutment surface 311 is also the second abutment surface 311. The placement area corresponding to the first orthographic projection area formed by the second limiting groove 312 is also the first limiting groove 122.

[0134] like Figure 13As shown, when the first orthographic projection area and the placement area are partially misaligned, that is, when the pressing member 300 moves to partially open the first limiting groove 122, the gap formed between the first abutment surface 121 and the second abutment surface 311, and between the first limiting groove 122 and the second limiting groove 312, is sufficient to allow the mounting protrusion 222 of the bushing 220 to be moved out. At this time, the mounting protrusion 222 in the bushing 220 can be pulled out substantially along the extension direction of the first abutment surface 121, for example, in the front-back direction and the left-right direction.

[0135] Or such as Figure 14 As shown, when the first orthographic projection area and the placement area are completely misaligned, that is, when the pressing member 300 moves to fully open the first limiting groove 122, the gap formed between the first abutment surface 121 and the second abutment surface 311, and between the first limiting groove 122 and the second limiting groove 312, is sufficient to allow the mounting protrusion 222 of the bushing 220 to be moved out. At this time, the mounting protrusion 222 in the bushing 220 can be pulled out substantially along the normal of the first abutment surface 121, for example, upwards.

[0136] In one embodiment, the bottom shell 110 also defines a receiving cavity beside the mounting cavity 111. The receiving cavity and the mounting cavity 111 are independently provided. Part of the pressing member 300 is received within the mounting cavity 111, and the remaining part extends into the receiving cavity. The retaining structure is received within the receiving cavity and is connected to the portion of the pressing member 300 that extends into the receiving cavity. Thus, it is equivalent to having the retaining structure separately located within the receiving cavity. This allows the retaining structure to not occupy space within the mounting cavity 111.

[0137] In the above embodiments, after the pressing member 300 maintains its posture under the action of the retaining structure, it can be configured to release the retaining structure's holding effect when subjected to a larger external force, allowing the pressing member 300 to continue moving. Alternatively, it can be configured to maintain the holding effect of the retaining structure regardless of the magnitude of the external force (referring to normal external force without damaging the structure), preventing the pressing member 300 from continuing to move unless the retaining structure's holding effect on the pressing member 300 is released.

[0138] When the pressing component 300 is rotatably mounted relative to the bottom shell 110, the retaining structure can be mounted at the rotatable connection between the pressing component 300 and the bottom shell 110, so that the retaining structure can both form sufficient structural support with the help of the bottom shell 110 and act directly on the pressing component 300.

[0139] Specifically, the pressing member 300 has a protruding shaft 350 at one end opposite to the brush body 210. The pressing member 300 can be rotatably mounted on the bottom shell 110 via the protruding shaft 350. The bottom shell 110 is provided with a support rib 610. The support rib 610 is located on the radial side of the protruding shaft 350, and the end face of the support rib 610 slides against the outer peripheral side of the protruding shaft 350. The retaining structure is located at the end face of the support rib 610 and / or the outer peripheral side of the protruding shaft 350.

[0140] Then as Figures 10 to 12 In one embodiment, a first flat surface 352 is partially provided on the outer peripheral side of the convex shaft 350. The end face of the support rib 610 is flat, forming a second flat surface 353. During the movement of the pressing member 300 relative to the bottom shell 110, the end face of the support rib 610, i.e., the second flat surface 353, slides against the outer peripheral side of the convex shaft 350. After the pressing member 300 moves to its position away from the bottom shell 110, the contact area between the second flat surface 353 and the first flat surface 352 is located directly below the center of gravity of the pressing member 300. The first flat surface 352 and the support rib 610 together constitute a retaining structure. At this time, the pressing member 300 maintains its posture under the action of the retaining structure, but when driven by a greater external force, the retaining effect of the retaining structure can be released, allowing the pressing member 300 to continue to move.

[0141] Or such as Figures 7 to 9 In another embodiment, a groove 351 is provided on the outer peripheral side of the convex shaft 350. The support rib 610 is elastically extendable and retractable in the direction approaching and away from the convex shaft 350. During the movement of the pressing member 300 relative to the bottom shell 110, the end face of the support rib 610 elastically abuts against the outer peripheral side of the convex shaft 350. And after the pressing member 300 moves into position in the direction away from the bottom shell 110, the support rib 610 elastically extends and inserts into the groove 351. The groove 351 and the support rib 610 together constitute a retaining structure. At this time, after the pressing member 300 maintains its posture under the action of the retaining structure, even if it is driven by a larger external force, the retaining effect of the retaining structure will not be released. The pressing member 300 cannot continue to move.

[0142] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
