Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more particularly to a cleaning module and cleaning equipment. Background Technology

[0002] Some cleaning equipment features a mopping function, which is achieved through a cleaning module at the bottom of the equipment. These cleaning modules include disc-type mop assemblies, roller-type mop assemblies, and belt-type mop assemblies. Among these, the belt-type mop assembly offers advantages over disc-type and roller-type mop assemblies, such as a larger mopping area, stronger pressure on the floor, and a more thorough mopping effect.

[0003] Typically, a tracked mop assembly includes a mop holder and a mop. The mop is positioned on the outside of the mop holder, and the tracked mop assembly is mounted on the robot vacuum cleaner via the mop holder. When changing the mop, the width of the mop holder needs to be adjusted to facilitate mop loading and unloading. However, the existing mop holder width adjustment is inconvenient, making mop loading and unloading difficult. Utility Model Content

[0004] This application provides a cleaning module and cleaning equipment to improve the technical problem of inconvenient cloth adjustment leading to inconvenience in cloth handling.

[0005] The first aspect of this application provides a cleaning module, which includes an inner support frame, a cleaning component, a connecting bracket, an outer support component, and a pull component. The inner support frame includes a first bracket and a second bracket, which have a first gap and a second gap. The cleaning component is fitted onto the inner support frame, and the first and second brackets tension the cleaning component at the first gap and relax it at the second gap. The connecting bracket is disposed at one end of the inner support frame along its length, and one of the first and second brackets is fixedly connected to the connecting bracket, while the other is slidably engaged with the connecting bracket to allow the first and second brackets to move between the first and second gaps. The outer support component is disposed on the connecting bracket and slidably disposed between the first and second brackets to adjust the gap between the first and second brackets. The pull component is movably disposed on the outer support component and has a retracted position and a functional position. In the retracted position, the pull component is interference-fitted and / or snap-fitted with the outer support component. In the functional position, a portion of the pull component is separated from the outer support component, allowing external force to be applied to the separated portion of the pull component, thereby causing the outer support component to move.

[0006] The external support adjusts the distance between the first and second supports by the depth to which it extends into them. When the external support extends deeper, the distance between the first and second supports is the first distance, at which point the first and second supports tension the cleaning component. When the external support extends shallower or not at all between the first and second supports, the distance between them can be adjusted to the second distance. When the distance between the first and second supports is the second distance, the cleaning component is relaxed, allowing it to be removed from the first and second supports.

[0007] The outer support is mounted on the connecting bracket. To reduce impacts, the length of the outer support exposed outside the connecting bracket needs to be reduced, making it inconvenient to grip and difficult to slide away from the first and second brackets. This application addresses this by movably mounting a pull member on the outer support. When the pull member is in the retracted position, it is fixed to the outer support through an interference fit and / or snap-fit, preventing detachment. When the pull member is in the functional position, a portion of its structure separates from the outer support, allowing external force to be applied to the separated portion, facilitating movement of the outer support. For example, it allows operators to easily grasp the pull member and move it away from the inner support frame, adjusting the distance between the first and second brackets and facilitating the loading and unloading of cleaning components.

[0008] In an exemplary embodiment of this application, the connecting bracket is provided with a first groove, and the outer support member passes through the connecting bracket through the first groove. When the pull member is in the retracted position, the pull member does not extend beyond the opening side of the first groove away from the inner support frame.

[0009] When the depth of the outer support does not need to be adjusted, the pull member is in the retracted position. When the cleaning equipment is in operation, the pull member is usually in the retracted position. By setting the pull member not to extend beyond the opening side of the first groove away from the inner support frame, the pull member can be prevented from affecting the length of the cleaning module, reducing the risk of the pull member being bumped and damaged when the cleaning equipment is in operation, and improving the safety of the cleaning equipment during operation.

[0010] In an exemplary embodiment of this application, the outer support member is provided with a rotating shaft, and the pull member is connected to the rotating shaft. The pull member can rotate relative to the outer support member about the axis of the rotating shaft. When the pull member rotates to fit against the side of the outer support member away from the inner support frame, the pull member is in the retracted position. When the pull member rotates to form an angle with the side of the outer support member away from the inner support frame, the pull member is in the functional position.

[0011] The rotating shaft can be rotatably connected to the outer support member and fixedly connected to the tension member. The outer support member and the tension member are rotatably connected through the rotating shaft. Alternatively, the rotating shaft can be fixedly connected to the outer support member and rotatably connected to the tension member. The outer support member and the tension member are rotatably connected through the rotating shaft. Alternatively, the rotating shaft can be rotatably connected to the outer support member and rotatably connected to the tension member. The outer support member and the tension member are rotatably connected through the rotating shaft.

[0012] The relative rotation of the pull member and the outer support member allows the pull member to move between the functional position and the retracted position. When the pull member is in the retracted position, it fits against the side of the outer support member away from the inner support frame, reducing its impact on the length of the cleaning module and thus minimizing its influence on blind spots in the cleaning module. This also reduces the risk of damage from impacts. When the pull member is in the functional position, it forms an angle with the side of the outer support member away from the inner support frame, facilitating the application of external force to the pull member. This includes making it easier for operators to grip the pull member and thus allowing for easier adjustment of the depth to which the outer support member extends into the inner support frame.

[0013] In an exemplary embodiment of this application, the pull member is a frame structure, and the outer support member has a protrusion on the side away from the inner support frame. When the pull member is in the retracted position, the pull member surrounds the outer periphery of the protrusion.

[0014] The puller has a frame structure. When the puller is in the retracted position, it surrounds the outer periphery of the protrusion, which can reduce the space occupied by the puller along the length of the cleaning module, prevent the puller from affecting the overall length of the cleaning module, and also reduce the risk of the puller being damaged by bumps.

[0015] The frame structure allows operators to insert their fingers into the puller, making it easy for them to pull out the outer support, and thus facilitating the adjustment of the distance between the first and second supports, making it convenient to load and unload cleaning components.

[0016] In an exemplary embodiment of this application, a protrusion is provided on the outer periphery of the protrusion, and in the retracted position, the pull member is interference-fitted with the protrusion through the protrusion.

[0017] The interference fit between the pull member and the protruding part ensures the pull member is relatively fixed to the outer support, guaranteeing its stability and preventing it from being exposed outside the cleaning module due to relative movement between the pull member and the outer support during the cleaning equipment's operation. This reduces the risk of damage from impacts and ensures the cleaning equipment's passability. When the pull member needs to be used, applying force to it disengages it from the protrusion, facilitating locking and unlocking for convenient use.

[0018] In an exemplary embodiment of this application, an extension is provided at the end of the pull member away from the rotation axis, and a second groove is formed between the extension and the surface of the outer support member.

[0019] Rotating the pull member allows it to move from the retracted position to the functional position. The extension and the surface of the outer support form a second groove, which allows the operator to insert their fingers or other tools into for easy force application, thus facilitating the rotation of the pull member and improving ease of use.

[0020] In an exemplary embodiment of this application, a limiting hole is provided on the outer periphery of the outer support member, and a limiting protrusion is provided on the inner side of the frame of the pull member. The limiting protrusion engages with the limiting hole to restrict the rotation of the pull member and the outer support member.

[0021] The pull member has some elastic deformation capability. When the pull member rotates from the functional position to the retracted position, the limiting protrusion contacts the outer periphery of the outer support, causing the limiting protrusion and the pull member to undergo elastic deformation until the limiting protrusion is inserted into the limiting hole. The elastic deformation of the limiting protrusion and the pull member is restored, and the limiting protrusion and the limiting hole engage to restrict the relative rotation of the pull member and the outer support. The pull member is kept in the retracted position, avoiding the pull member from protruding due to the rotation of the pull member and the outer support during the operation of the cleaning equipment, reducing the risk of the pull member being damaged by collision, and reducing the risk of the cleaning equipment being obstructed.

[0022] When the pull member is needed, external force is applied to disengage the limiting protrusion from the limiting hole, allowing the pull member and the outer support member to rotate relative to each other.

[0023] In an exemplary embodiment of this application, the outer support includes a mounting groove, and a rotating shaft is disposed in the mounting groove; the frame structure of the pull member has an opening, and one end of the pull member near the opening is connected to the rotating shaft.

[0024] The mounting groove is used to install the rotating shaft. The two side walls of the mounting groove can form a limit to restrict the rotation of the pull part, eliminating the need for a separate limit component to restrict the rotation of the pull part.

[0025] In an exemplary embodiment of this application, a clearance area is provided on the side of the outer support member away from the inner support frame, and when the pull member is in the retracted position, the frame of the pull member is located within the clearance area.

[0026] By setting a clearance zone, on the one hand, it can be ensured that the pull part can rotate between the retracted position and the functional position. On the other hand, when the pull part is in the retracted position, it is located in the clearance zone, which can reduce the length of the pull part protruding from the outer support, or even make the pull part not protrude from the outer support. This improves the problem of the pull part affecting the overall length of the cleaning module and reduces the cleaning blind spots of the cleaning module.

[0027] In an exemplary embodiment of this application, the outer support member includes a base and an outer support portion. A pull member is mounted on the base; the base includes a limiting groove penetrating the base, the limiting groove being disposed at the mounting groove and extending away from the clearance area; the outer support portion is fixed to the base, and the outer support portion extends through the connecting bracket and between the first bracket and the second bracket; wherein, the pull member includes a limiting block, the limiting block being located within the limiting groove, and the end wall of the limiting groove being located within the rotation path of the limiting block, so that when the limiting block rotates to the end wall of the limiting groove, the limiting block is restricted from continuing to rotate.

[0028] The base is located on the side of the connecting bracket away from the first and second brackets, and the outer support extends through the connecting bracket to the side of the connecting bracket closer to the first and second brackets. By setting a limiting groove on the base and a limiting block on the pull member, when the limiting block rotates to the end wall of the limiting groove, the limiting block restricts the pull member from continuing to rotate, thereby limiting the rotation range of the pull member, preventing excessive rotation of the pull member, and facilitating the use of the pull member.

[0029] A second aspect of this application provides a cleaning device, which includes a device body and a cleaning module as described above, wherein the cleaning module is installed on the device body.

[0030] The cleaning module of the cleaning equipment in this application features a pull member that is movably connected to the external support. When the pull member is in the retracted position, it reduces its occupancy along the length of the cleaning module, thus minimizing its impact on the module's length and cleaning range. When in the functional position, the pull member facilitates its use. By moving the external support along the length of the cleaning module, the distance between the first and second supports can be adjusted, improving the ease of loading and unloading the cleaning components.

[0031] In combination with existing technologies, the beneficial effects of this application are as follows: Existing external supports typically cause the first and second supports to be close to the connecting support when they are at a certain distance, making it inconvenient to pull the external support away from the first and second supports. This application addresses this by movably mounting a pull member on the external support. When the external support does not require adjustment, the pull member is in a retracted position, reducing the impact on the length of the cleaning module, avoiding increased blind spots, and ensuring the cleaning range of the cleaning module. When the external support needs to move along the length of the cleaning module, the pull member is adjusted to its functional position, separating part of the pull member from the external support. This facilitates applying external force to the separated part, for example, allowing the operator to easily grasp the separated part and pull the external support, thus facilitating adjustment of the distance between the first and second supports and improving the loading, cleaning, and replacement of the cleaning components.

[0039] Please see Figures 1 to 14 This application provides a cleaning module 10 and a cleaning device. By movably setting a pull member 600 on the outer support member 500, the convenience of operating the outer support member 500 can be effectively improved, while reducing the impact on the length direction of the cleaning module 10.

[0040] Please see Figures 1 to 14The cleaning module 10 includes an inner support frame 100, a cleaning component 300, a connecting bracket 400, an outer support component 500, and a pull component 600. The inner support frame 100 includes a first bracket 110 and a second bracket 120, with the second bracket 120 having a first gap and a second gap with the first bracket 110. The cleaning component 300 is sleeved on the inner support frame 100. The first bracket 110 and the second bracket 120 tension the cleaning component 300 at the first gap and relax it at the second gap. The connecting bracket 400 is located at one end of the inner support frame along its length. One of the first bracket 110 and the second bracket 120 is fixedly connected to the connecting bracket 400, while the other is slidably engaged with the connecting bracket 400, so that the first bracket 110 and the second bracket 120 are tensioned at the first gap. The outer support 500 is disposed on the connecting bracket 400 and is slidably disposed between the first bracket 110 and the second bracket 120 to adjust the distance between the first bracket 110 and the second bracket 120; the pull member 600 is movably disposed on the outer support 500, and the pull member 600 has a retracted position and a functional position. In the retracted position, the pull member 600 is interference-fitted and / or snapped with the outer support 500. In the functional position, a portion of the pull member 600 is separated from the outer support 500 so that external force can be applied to the part where the pull member 600 is separated from the outer support 500, thereby causing the outer support 500 to move.

[0041] The outer support 500 adjusts the distance between the first support 110 and the second support 120 by the depth to which it extends into them. When the outer support 500 extends to a deeper depth, the distance between the first support 110 and the second support 120 is the first distance, at which point the first support 110 and the second support 120 tension the cleaning component 300. When the outer support 500 extends to a shallower depth or does not extend into the space between the first support 110 and the second support 120, the distance between the first support 110 and the second support 120 can be adjusted to the second distance. When the distance between the first support 110 and the second support 120 is the second distance, the cleaning component 300 is relaxed, allowing it to be removed from the first support 110 and the second support 120.

[0042] The outer support member 500 is mounted on the connecting bracket 400. To reduce impacts, the length of the outer support member 500 exposed outside the connecting bracket 400 needs to be reduced. This makes the outer support member 500 inconvenient to hold and makes it difficult for it to slide away from the first bracket 110 and the second bracket 120. This application addresses this by movably mounting a pull member 600 on the outer support member 500. When the pull member 600 is in the retracted position, it is relatively fixed to the outer support member 500. The fixing method can be an interference fit between the pull member 600 and the outer support member 500, a snap-fit ​​between the pull member 600 and the outer support member 500, or a combination of both. This prevents the pull member 600 from detaching from the outer support member 500, reducing the risk of impacts. The pull member 600 and the outer support member 500 are interference-fitted and / or snap-fitted together, so that the pull member 600 and the outer support member 500 fit closely together, thereby reducing the influence of the pull member 600 on the length direction of the cleaning module 10. When the pull member 600 is in the functional position, part of the pull member 600 is separated from the outer support member 500, which facilitates the application of external force to the part of the pull member 600 that is separated from the outer support member 500. For example, it is convenient for the operator to grab the pull member 600, and then convenient for the operator to pull the pull member 600 to move the outer support member 500 away from the first bracket 110 and the second bracket 120, so as to adjust the distance between the first bracket 110 and the second bracket 120 and facilitate the loading and unloading of the cleaning component 300.

[0043] For example, the first support 110 includes an active roller and a first frame. The active roller is connected to the drive mechanism, and the first frame provides support for the active roller to ensure that the active roller can rotate about the axis of the active roller.

[0044] The second support 120 includes a driven roller and a second frame, the second frame providing support for the driven roller so that the driven roller can rotate about its axis.

[0045] The cleaning component 300 is mounted on the drive roller and the driven roller. The drive mechanism drives the drive roller to rotate, which in turn drives the cleaning component 300 to move, so that the cleaning component 300 contacts the surface to be cleaned and cleans the surface.

[0046] For example, the axis of the active roller is in the length direction of the cleaning module 10, and the line connecting the axis of the active roller and the axis of the driven roller is in the width direction of the cleaning module 10.

[0047] The connecting bracket 400 is located at one end of the inner support frame 100 along its length. The length of the inner support frame 100 is the same as the length of the cleaning module 10. The first frame is fixed to the connecting bracket 400, and the second bracket 120 is movably connected to the connecting bracket 400, allowing the second bracket 120 to move along the width of the cleaning module 10. The fixing methods between the connecting bracket 400 and the first frame include, but are not limited to, snap-fit ​​connection, adhesive connection, and bolt connection. The connecting bracket 400 can also be integrally formed with the first frame, or a portion of the connecting bracket 400 can be integrally formed with the first frame, with the remaining components of the connecting bracket 400 then assembled.

[0048] Of course, as optional methods, the second frame can be fixed relative to the connecting bracket 400, and the fixing methods include, but are not limited to, snap-fit ​​connection, adhesive connection, bolt connection, and integral molding; the first frame can be movably connected to the connecting bracket 400. Alternatively, the second frame can be movably connected to the connecting bracket 400, and the first frame can also be movably connected to the connecting bracket 400, so that the first bracket 110 and the second bracket 120 can move relative to each other along the width direction of the cleaning module 10. The connection method between the first frame, the second frame, and the connecting bracket 400 can also be other existing connection methods, which will not be elaborated in this application.

[0049] For example, the first frame and the second frame are slidably connected, and an elastic tension member is provided between the first frame and the second frame. The elastic tension member can be an elastic structure such as a tension spring, so as to apply a force to the first frame and the second frame when the distance between the first frame and the second frame is not the second distance, so that the first frame and the second frame tend to be kept at the second distance.

[0050] Please see Figure 3 For example, the outer support member 500 has a first inclined surface on the side opposite to the second bracket 120, and the second bracket 120 has a second inclined surface on the side opposite to the outer support member 500. When the outer support member 500 extends between the first bracket 110 and the second bracket 120, the first and second inclined surfaces interact, causing the first bracket 110 and the second bracket 120 to move away from each other. When the outer support member 500 is withdrawn between the first bracket 110 and the second bracket 120, the elastic tension member applies a force to the first bracket 110 and the second bracket 120, causing the first bracket 110 and the second bracket 120 to move closer together until the first bracket 110 and the second bracket 120 move to the second distance. At this point, the cleaning member 300 is in a relaxed state, facilitating the removal, replacement, and cleaning of the cleaning member 300.

[0051] Please see Figure 2In one embodiment, a first groove 410 is provided on the side of the connecting bracket 400 away from the inner support frame 100. The first groove 410 is located on the connecting bracket 400 away from the inner support frame 100 along the length direction of the cleaning module 10, that is, the first groove 410 is located on the outside of the connecting bracket 400. The outer support member 500 is inserted between the first bracket 110 and the second bracket 120 through the first groove 410. When the outer support member 500 adjusts the distance between the first bracket 110 and the second bracket 120 to a first distance, the end of the outer support member 500 does not exceed the first groove 410. The first groove 410 protects the outer support member 500, preventing the outer support member 500 from exceeding the connecting bracket 400 and reducing the risk of the outer support member 500 being damaged by bumps.

[0052] When the pull member 600 is in the retracted position, it does not extend beyond the opening side of the first groove 410 away from the inner support frame 100. When the depth of the outer support member 500 does not need adjustment, the pull member 600 is in the retracted position. In other words, the pull member 600 is usually in the retracted position when the cleaning equipment is in operation. By ensuring that the pull member 600 does not extend beyond the opening side of the first groove 410 away from the inner support frame 100, the pull member 600 does not affect the original length of the cleaning module 10. On the one hand, this ensures the passability of the cleaning equipment, does not affect the cleaning range of the cleaning module 10, and avoids increasing blind spots. On the other hand, it reduces the risk of damage to the pull member 600 during operation, increases its service life, and improves the safety of the cleaning equipment during operation.

[0053] Please see Figure 4 and Figure 12 In one embodiment, the outer support member 500 is provided with a rotating shaft 510, and the pull member 600 is connected to the rotating shaft 510. The pull member 600 can rotate relative to the outer support member 500 about the axis of the rotating shaft 510. When the pull member 600 rotates to fit against the side of the outer support member 500 away from the inner support frame 100, the pull member 600 is in a retracted position. When the pull member 600 rotates to form an angle with the side of the outer support member 500 away from the inner support frame 100, the pull member is in a functional position.

[0054] The rotating shaft 510 can be rotatably connected to the outer support member 500 and fixedly connected to the pull member 600. The outer support member 500 and the pull member 600 are rotatably connected through the rotating shaft 510. For example, the rotating shaft 510 and the pull member 600 are integrally formed, and the outer support member 500 is provided with a rotating shaft mounting hole. The rotating shaft 510 extends into the hole and is rotatably connected to the outer support member 500.

[0055] The rotating shaft 510 can also be fixedly connected to the outer support member 500 and rotatably connected to the pull member 600. The outer support member 500 and the pull member 600 are rotatably connected through the rotating shaft 510. For example, the rotating shaft 510 and the outer support member 500 are integrally formed, and the pull member 600 is provided with a rotating shaft mounting hole. The rotating shaft 510 is inserted into the rotating shaft mounting hole and rotatably connected to the pull member 600.

[0056] The rotating shaft 510 can also be rotatably connected to the outer support member 500 and the pull member 600, with the outer support member 500 and the pull member 600 rotatably connected via the rotating shaft 510. For example, the outer support member 500 and the pull member 600 are provided with rotating shaft mounting holes at corresponding positions, and the rotating shaft 510 is inserted into the two rotating shaft mounting holes to rotatably connect the outer support member 500 and the pull member 600.

[0057] The relative rotation of the pull member 600 and the outer support member 500 allows the pull member 600 to move between a functional position and a retracted position. When the pull member 600 is in the retracted position, it fits against the side of the outer support member 500 away from the inner support frame 100, reducing the impact of the pull member 600 on the length of the cleaning module 10, thereby reducing the impact on the cleaning blind spots of the cleaning module 10 and reducing the risk of the pull member 600 being damaged by bumps. When the pull member 600 is in the functional position, it forms an angle with the side of the outer support member 500 away from the inner support frame 100, facilitating the application of external force to the pull member 600. For example, it makes it easier for operators to hold the pull member 600, thus facilitating the application of external force to the outer support member 500 and adjusting the depth of the outer support member 500 extending into the inner support frame 100.

[0058] For example, the angle between the pull member 600 and the outer support member 500 on the side away from the inner support frame 100 allows fingers to pass through, so that the operator can pull the edge of the pull member 600 after passing through the gap between the pull member 600 and the outer support member 500.

[0059] Please see Figure 4 and Figure 7 The pull member 600 is a frame structure. The outer support member 500 has a protrusion 520 on the side opposite to the inner support member 100. When the pull member 600 is in the retracted position, the pull member surrounds the outer periphery of the protrusion 520.

[0060] The frame structure allows operators to insert their fingers into the puller 600, making it easy for them to pull out the outer support 500, thereby facilitating the adjustment of the distance between the first bracket 110 and the second bracket 120, and making it convenient to load and unload the cleaning component 300.

[0061] The frame structure of the tie element 600 can be a closed frame structure or a frame structure with an opening 630; the shape of the frame structure can be triangular, quadrilateral, pentagonal, etc., corresponding to three borders 640, four borders 640, or five borders 640, etc. The shape of the frame structure can also be circular, elliptical, etc., and the shape of the frame structure can also be a combination of multiple shapes. When the pull member 600 is in the retracted position, at least a portion of its sidewalls 640 are fitted around the outer periphery of the protrusion 520. This reduces the space occupied by the pull member 600 along the length of the cleaning module 10, thereby reducing the risk of the pull member 600 being damaged by impact. Preferably, when the pull member 600 is in the retracted position, all of its sidewalls 640 are fitted around the outer periphery of the protrusion 520. For example, when the pull member 600 is a square frame with four sidewalls 640, two sidewalls 640 of the pull member 600 can be fitted around the outer periphery of the protrusion 520, three sidewalls 640 can be fitted around the outer periphery of the outer support member 500, or all four sidewalls 640 can be fitted around the outer periphery of the outer support member 500. This reduces the length of the pull member 600 protruding from the outer support member 500 along the length of the cleaning module 10, thereby reducing the impact on the length of the cleaning module 10 and reducing the risk of the pull member 600 being damaged by impact.

[0062] For example, the protrusion 520 protrudes outward from the cleaning module 10 along the length direction of the cleaning module 10. The protrusion 520 is a square protrusion 520, and the pull member 600 is a square frame structure. When the pull member 600 is in the retracted position, the pull member 600 surrounds the outer periphery of the protrusion 520.

[0063] Furthermore, when the pull member 600 is in the retracted position, it is flush with the protrusion 520, making the pull member 600 flush with the outer support member 500, thus reducing the impact of the pull member 600 on the length of the cleaning module 10.

[0064] A protrusion 521 is provided on the outer periphery of the protrusion 520, and the pull member 600 is interference-fitted with the protrusion 521. The interference fit between the pull member 600 and the protrusion 521 fixes the pull member 600 relative to the outer support 580, ensuring the stability of the pull member 600 and preventing it from being exposed outside the cleaning module 10 due to relative movement between the pull member 600 and the outer support 500 during the movement of the cleaning equipment. This reduces the risk of damage to the pull member 600 from impacts and ensures the passability of the cleaning equipment. When the pull member 600 needs to be used, a force is applied to it to disengage it from the protrusion 521, facilitating locking and unlocking of the pull member 600 for convenient use.

[0065] For example, the top of the protrusion 521 is provided with a guide surface, which is an arc-shaped surface or an inclined surface. By setting the guide surface, the height of the protrusion 521 near the outside of the cleaning module 10 is less than the height of the protrusion 521 near the inside of the cleaning module 10. This ensures that when the protrusion 521 is worn near the outside of the cleaning module 10, the pull member 600 and the protrusion 521 can be interference-fitted, which facilitates the clamping of the pull member 600 and the protrusion 521.

[0066] Please see Figure 10 and Figure 11 In one embodiment, a limiting hole 540 is provided on the outer periphery of the outer support member 500; a limiting protrusion 620 is provided on the inner side of the frame 640 of the pull member 600, and the limiting protrusion 620 cooperates with the limiting hole 540 to restrict the rotation of the pull member 600 and the outer support member 500.

[0067] The pull member 600 has some elastic deformation capability. When the pull member 600 rotates from the functional position to the retracted position, the limiting protrusion 620 contacts the outer periphery of the outer support member 500, causing the limiting protrusion 620 and the pull member 600 to undergo elastic deformation until the limiting protrusion 620 inserts into the limiting hole 540. The limiting protrusion 620 and the pull member 600 then return to their elastic deformation state. The limiting protrusion 620 and the limiting hole 540 cooperate to restrict the relative rotation of the pull member 600 and the outer support member 500, keeping the pull member 600 in the retracted position. This prevents the pull member 600 from protruding due to rotation during the operation of the cleaning equipment, reducing the risk of damage from impacts and the risk of obstruction to the movement of the cleaning equipment. When the pull member 600 needs to be used, external force is applied to disengage the limiting protrusion 620 from the limiting hole 540, allowing the pull member 600 and the outer support member 500 to rotate relative to each other.

[0068] The limiting hole 540 can be a round hole, a square hole, etc. The limiting protrusion 620 is adapted to the limiting hole 540. Preferably, the limiting hole 540 is a round hole so that the limiting protrusion 620 can be inserted into the limiting hole 540.

[0069] For example, the end of the limiting protrusion 620 is rounded or chamfered to guide the limiting protrusion 620 into the limiting hole 540 more easily.

[0070] Please see Figure 5 In one embodiment, the end of the pull member 600 away from the rotation shaft 510 is provided with an extension 610, and the extension 610 and the surface of the outer support member 500 form a second groove 611.

[0071] The extension 610 is located on the side of the pull member 600 near the outside of the cleaning module 10 and extends away from the rotation axis 510. When the pull member 600 is in the retracted position, the extension 610 and the surface of the outer support member 500 form a second groove 611. The operator can insert his / her fingers or other operating objects into the second groove 611 to easily apply force, thereby facilitating the rotation of the pull member 600 and improving the ease of use.

[0072] Please see Figure 4 In one embodiment, the outer support 500 includes a second buckle 530, which cooperates with a first buckle on the connecting bracket 400 or a first buckle on the main body of the equipment to restrict the outer support 500 from sliding away from the inner support 100; the frame 640 of the pull member 600 near the rotation shaft 510 is sleeved on the outer periphery of the outer support 500, and the second buckle 530 is located in the rotation path of the pull member 600 to restrict the rotation angle of the pull member 600.

[0073] The movement of the outer support 500 along the length of the cleaning module 10 is restricted by the cooperation of the first and second latches 530. The rotation angle of the pull member 600 is restricted by positioning the second latch 530 along the rotation path of the frame 640 of the pull member 600. The second latch 530 both restricts the movement of the outer support 500 and the rotation angle of the pull member 600, eliminating the need for separate limiting structures and reducing production costs.

[0074] For example, the second buckle 530 slides relative to the connecting bracket 400 along the width direction of the cleaning module 10, so that the second buckle 530 engages or disengages from the first buckle. When the second buckle 530 engages with the first buckle, the outer support 500 can be prevented from falling off, thereby preventing the distance between the first bracket 110 and the second bracket 120 from changing, and preventing the cleaning component 300 from loosening or falling off.

[0075] Please see Figures 9 to 11 In one embodiment, the outer support member 500 includes a mounting groove 550, and the rotating shaft 510 is disposed in the mounting groove 550. The mounting groove 550 is used to mount the rotating shaft 510, and the two side walls of the mounting groove 550 can form a limit to restrict the rotation of the pull member 600, so there is no need to set a separate limit component to restrict the rotation of the pull member 600.

[0076] The outer support 500 has a clearance area 560 on the side away from the first bracket 110 and the second bracket 120. The frame structure of the pull member 600 has an opening 630. The end of the pull member 600 near the opening 630 is connected to the rotation shaft 510. When the pull member 600 is in the retracted position, the edge 640 of the pull member 600 is located in the clearance area 560.

[0077] For example, the clearance area 560 extends from the mounting groove 550 to one end of the outer support member 500. By setting the clearance area 560, on the one hand, it can be ensured that the pull member 600 can rotate between the retracted position and the functional position. On the other hand, when the pull member 600 is in the retracted position, it is located in the clearance area 560, which can reduce the length of the pull member 600 protruding from the outer support member 500, or even make the pull member 600 not protrude from the outer support member 500. This improves the problem that setting the pull member 600 affects the overall length of the cleaning module 10 and reduces the cleaning blind spot of the cleaning module 10.

[0078] For example, the frame mechanism of the pull member 600 is a square frame with an opening 630, and the clearance area 560 is concave in shape. The square frame is adapted to the concave clearance area 560 to reduce the length of the pull member 600 protruding from the outer support member 500 along the length direction of the cleaning module 10. Preferably, the pull member 600 and the outer support member 500 are flush with the side facing outward from the cleaning module 10.

[0079] Please see Figures 12 to 14 In one embodiment, the outer support member 500 includes a base 570 and an outer support portion 580. A pull member 600 is installed on the base 570, and the outer support portion 580 is fixed to the base 570. The outer support portion 580 extends through the connecting bracket 400 and between the first bracket 110 and the second bracket 120. The outer support portion 580 adjusts the distance between the first bracket 110 and the second bracket 120 by the depth of its extension between them.

[0080] Please see Figure 12 and Figure 13 The base 570 includes a limiting groove 571 extending through the base 570. The limiting groove 571 is located at the mounting groove 550 and extends away from the clearance area 560. The pull member 600 includes a limiting block 650 located within the limiting groove 571, with the end wall of the limiting groove located along the rotation path of the limiting block 650. This restricts the limiting block 650 from continuing to rotate when it reaches the end wall of the limiting groove. By providing a limiting groove 571 on the base 570 and a limiting block 650 on the pull member 600, the limiting block 650 restricts the pull member 600 from continuing to rotate when it reaches the end wall of the limiting groove 571, thereby limiting the rotation range of the pull member 600, preventing excessive rotation, and facilitating the use of the pull member 600.

[0081] In one embodiment, the protrusion 520 is located at the seat 570, and the handle is a square frame structure fitted over the protrusion 520. The side edge of the seat 570 facing the cleaning module 10 is rounded to avoid interference between the handle and the seat 570 when the handle and the outer support 500 rotate relative to each other, thus ensuring that the handle and the outer support 500 can rotate relative to each other.

[0082] Please see Figure 1 The second aspect of this application provides a cleaning device, which includes a device body 20 and a cleaning module 10 as described above, wherein the cleaning module 10 is installed on the device body 20.

[0083] The cleaning module 10 of the cleaning equipment of this application, by providing a pull member 600 movably connected to the outer support member 500, reduces the occupancy of the pull member 600 along the length of the cleaning module 10 when it is in the retracted position, thereby reducing the impact of the pull member 600 on the length and cleaning range of the cleaning module 10. When the pull member 600 is in the functional position, it is convenient to use. The pull member 600 drives the outer support member 500 to move along the length of the cleaning module 10, thereby adjusting the distance between the first bracket 110 and the second bracket 120, facilitating the adjustment of the distance between the first bracket 110 and the second bracket 120, and improving the convenience of loading and unloading the cleaning component 300.

[0084] The main body 20 of the cleaning equipment of this application can accommodate various components of the cleaning equipment. The shape of the main body 20 can be any shape, such as cylindrical, elliptical, or D-shaped.

[0085] The cleaning equipment also includes a walking system conventionally provided on existing cleaning equipment, used to drive the machine body to move independently on the surface to be cleaned. The specific structure of the walking system and the connection structure between the walking system and the main body 20 of the equipment can be referred to the relevant structural descriptions in existing cleaning equipment, and will not be repeated here.

[0086] Optionally, in one embodiment, the cleaning device may further include a side brush and a roller brush, both located at the bottom of the device body 20. Along the travel direction of the cleaning device, both the side brush and the roller brush are positioned in front of the cleaning module 10. The side brush may be located at the edge of the device body 20 and can rotate via a rotating mechanism, such as a motor, a combination of a motor and a reducer. When the side brush rotates, it can gather debris from the edge of the device body 20 towards the inside of the device body 20, thereby increasing the cleaning range of the cleaning device. The side brush can be a rubber strip or a bristle brush, as long as it can clean the ground; there are no limitations. The roller brush is rotatably disposed within a roller brush cavity at the bottom of the device body 20. During its rotation, the roller brush can sweep away debris on the ground. The number of roller brushes can be set according to specific requirements; there is no limitation in this embodiment.

[0087] Along the travel direction of the main body 20, the side brush and roller brush are positioned in front of the cleaning module 10. This facilitates the cleaning operation of dry sweeping followed by wet mopping, and also facilitates the layout of the internal space of the main body 20.

[0088] In addition to the above, the cleaning equipment may also include a sensing system and a control system. The sensing system and control system are electrically connected. The sensing system obtains the distance between the edge of the equipment body 20 and the obstacle, and the control system controls the cleaning equipment to perform corresponding actions based on this distance. For example, it controls the cleaning equipment to perform actions such as obstacle avoidance, edge cleaning, and returning to the base station.

[0089] Of course, cleaning equipment may also include other components; please refer to existing cleaning equipment, which will not be elaborated upon in this application.

[0090] The cleaning module 10 and cleaning equipment of this application, by movably setting a pull member 600 on the outer support member 500, allow the pull member 600 to be in a retracted position when the outer support member 500 does not need adjustment, reducing the impact on the length direction of the cleaning module 10, avoiding increasing the cleaning blind spots of the cleaning module 10, and ensuring the cleaning range of the cleaning module 10. When the outer support member 500 needs to move along the length direction of the cleaning module 10, the pull member 600 is adjusted to a functional position, and part of the pull member 600 separates from the surface of the outer support member 500. This facilitates the application of external force to the part of the pull member 600 that is detached from the outer support member 500, such as making it easier for the operator to hold the pull member 600, making it easier for the operator to pull the outer support member 500, and facilitating the adjustment of the distance between the first bracket 110 and the second bracket 120. This also facilitates the loading, unloading, cleaning, and replacement of the cleaning component 300. Therefore, this application effectively overcomes some practical problems in the prior art and thus has high utilization value and significance.

[0091] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
