An elastic member is provided between the two frames, and the elastic member provides an elastic force to move the two frames away from each other, thereby allowing the frames and the rollers to tension the cleaning cloth. When the cleaning cloth needs to be disassembled, the two frames need to be pressed by hand so that the two frames are close to each other and are in a state of a small distance. In order to keep the two frames in a state of a small distance and thereby relax the cleaning cloth, the user needs to continue pressing the two frames to overcome the elastic force provided by the elastic member to drive the two frames away from each other.

[0004] In the prior art, in order to avoid using both hands to continuously press the two frames when disassembling and assembling the cleaning cloth, a locking structure such as a lock buckle is generally required. The locking structure can be triggered and lock the two frames after the two frames are close to each other to a set distance, so as to free both hands. However, the above-mentioned locking structure needs to be used in conjunction with an unlocking member, which is exposed and arranged at one end of the frame along the axis parallel to the roller body, and the unlocking member needs to be connected to the locking structure through a transmission member. In this setting, the locking structure, the unlocking member and the transmission member will occupy a large space in the cleaning component, making the entire structure of the cleaning component more complicated and bulky, and it is not convenient to achieve a lightweight design of the cleaning component and the floor brush.

[0020] Beneficial effects of one or more of the above technical solutions:

[0021] (1) In this solution, the guide and limit assembly includes a guide member connected to the first frame and a limit member connected to the second frame; the limit member has a slide groove section connected end to end, and the guide member can cooperate with the slide groove section, so that when the guide member moves in the slide groove section, the frame assembly can switch between the loose adjustment state and the tensioned adjustment state. In this setting method, the cooperation of the guide member and the limit member is used to achieve the guidance and limitation of the frame assembly when switching between the loose adjustment state and the tensioned adjustment state, which is convenient for using the guide and limit assembly to keep the first frame and the second frame in the frame assembly in the loose adjustment state and the tensioned adjustment state away from each other. There is no need to additionally set up a corresponding locking structure, which can achieve self-locking of the bracket, and it is also convenient to save the structural settings of the locking structure, unlocking member, etc. at the frame assembly, reduce the space occupied by the frame assembly for the cleaning device, and thus facilitate the lightweight design of the cleaning assembly, reduce the cost, reduce the space density and structural complexity, and greatly improve the convenience of operation.

[0022] (2) In this solution, in the slack adjustment state, the guide moves from the first sliding section to the first locking section, and from the first locking section to the second locking section; in the tension adjustment state, the guide moves from the second locking section to the second sliding section, and from the second sliding section to the first sliding section. The guide can enter the first locking section at the last moment of the slack adjustment state (i.e., the two frames are adjusted to the shortest distance by pressing the frames with both hands), and enter the second locking section along the first locking section. At this time, the tendency of the two frames to move away from each other due to the elastic force will be blocked by the locking of the guide in the second locking section, so that the two frames can maintain the slack adjustment state to free the user's hands.

[0023] In addition, in the tension adjustment state, the user presses the two frames again to make the distance between the two frames closer so that the guide member enters the second sliding section from the second locking section to disengage the locking state, and then utilizes the elastic force of the two frames to move the two frames away from each other and reset the guide member to the first sliding section.

[0024] That is, the cooperation between the closed-loop slide groove and the guide member in the present solution makes it easy for the user to complete the locking and unlocking cycle by pressing the frame twice. There is no need to set up an additional corresponding locking structure to enable the frame assembly to tighten the cleaning cloth or relax the cleaning cloth, and it is easy to save the space occupied by the frame assembly in the cleaning equipment.

[0041] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, an indirect connection through an intermediate medium, or the internal connection of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] like Figure 1-Figure 5 As shown, this embodiment provides a cleaning device with guidance and limit, including a frame assembly, a cleaning assembly and a guidance and limit assembly, the frame assembly includes two frames connected side by side (i.e., the first frame 31 and the second frame 32 shown in the figure); the cleaning assembly includes a first roller body 33 and a second roller body 34 which are rotatably connected to the first frame body 31 and the second frame body 32 respectively, and the outer rings of the first roller body 33 and the second roller body 34 are provided with cleaning cloths; wherein the spacing between the first frame body 31 and the second frame body 32 can be adjusted so that the frame assembly has a slack adjustment state for relaxing the cleaning cloth and a slack adjustment state for stretching the cleaning cloth. Tight tensioning adjustment state; the guide limit assembly includes a guide member connected to the first frame and a limit member 41 connected to the second frame; the limit member 41 has a slide groove section connected end to end, and the guide member can cooperate with the slide groove section, so that when the guide member moves in the slide groove section, the frame assembly can switch between the loose adjustment state and the tensioning adjustment state, so that the first frame 31 and the second frame 32 have a close state and a distant state; wherein, in the close state and the distant state, the guide member and the limit member 41 can abut and limit in the moving direction of the guide member along the slide groove section.

[0043] The cleaning device 3 is a part of the cleaning equipment. Specifically, the cleaning device 3 can be installed in the lower receiving cavity 11 of the sweeping robot. In some other embodiments, the cleaning device 3 can also be installed in the receiving cavity 11 below the floor brush of the floor scrubber.

[0044] See again Figure 3 Here, the first frame 31 and the second frame 32 are both square frame structures. The first frame 31 and the second frame 32 are arranged side by side, and there are multiple sets of guide structures between the first frame 31 and the second frame 32. The guide structure includes a guide column 311 and a guide hole. One of the guide column 311 and the guide hole is provided on the first frame 31, and the other is provided on the second frame 32. More specifically, the extension direction of the guide column 311 and the guide hole is a first direction, and the first direction is the direction in which the first frame 31 and the second frame 32 approach each other or move away from each other. Here, the cross-section of the guide column 311 and the guide hole can be square, circular, elliptical or other different shapes, as long as the cross-section is a fixed cross-section. More specifically, the structure and size of the first frame 31 and the second frame 32 can be the same or different.

[0045] In addition, the first roller body 33 and the second roller body 34 are rotatably connected to the first frame body 31 and the second frame body 32 respectively through the rotating shaft, and the axis direction of the first roller body 33 and the second roller body 34 is perpendicular to the first direction. When the cleaning device 3 is installed in the cleaning equipment, the first direction is the front-back direction of the cleaning equipment when it moves along the surface to be cleaned.

[0046] Specifically, the cleaning cloth is a closed loop structure, and the cleaning cloth loop is sleeved outside the first roller body 33 and the second roller body 34 to form a crawler type cleaning assembly. The distance between the first frame and the second frame can be adjusted (that is, the first frame and the second frame can be closer to each other or farther away from each other along the first direction under the guidance of the guide column 311).

[0047] The above-mentioned slack adjustment state refers to the adjustment process in which the first frame 31 and the second frame 32 are brought closer to each other to reduce the distance between the first roller 33 and the second roller 34, thereby making the cleaning cloth in a slack state and not being tensioned by the rollers. Similarly, the above-mentioned tension adjustment state refers to the adjustment process in which the first frame 31 and the second frame 32 are moved away from each other to increase the distance between the first roller 33 and the second roller 34, thereby making the cleaning cloth tensioned by the rollers.

[0048] In this embodiment, the first frame is rotatably connected to the end of the guide member away from the stopper 41, or a deformable connection member is fixed at the connection between the two, so that the guide member can swing relative to the first frame to avoid position interference between the guide member and the first frame. The stopper 41 is fixedly connected to the second frame, and the fixed connection method can be gluing or bolting.

[0049] In this embodiment, the slide groove section is arranged on the upper surface or the lower surface of the stopper 41. In other embodiments, a hollow cavity can be arranged in the middle of the stopper 41, and an upper slide groove section is arranged on the upper wall or the bottom wall of the cavity.

[0050] It should be noted that in this embodiment, when the guide member moves in the slide slot, the frame assembly can switch between a loose adjustment state and a tight adjustment state. The power for the guide member to move in the slide slot again comes from the movement of the first frame 31 and the second frame 32 moving closer to or away from each other, and the power comes from the drive of the user's hands or the drive of the spring 312 and the power element.

[0051] See also Figure 6 In this embodiment, the slide groove section has a first sliding section 411, a first locking section 412, a second locking section 413 and a second sliding section 414 which are connected in sequence end to end; in a slack adjustment state, the guide member can move from the first sliding section 411 to the first locking section 412, and from the first locking section 412 to the second locking section 413; in a tension adjustment state, the guide member can move from the second locking section 413 to the second sliding section 414, and from the second sliding section 414 to the first sliding section 411.

[0052] Specifically, in the relaxed adjustment state, the first frame 31 and the second frame 32 are close to each other, and then the two frames drive the guide member to move along the first end of the first sliding section to the first end of the first locking section, so as to reduce the size of the entire guide limit assembly in the first direction. When the first frame 31 and the second frame 32 stop approaching each other, the two frames move away from each other for a distance, so that the guide member moves along the first end of the first locking section to the tail end of the first locking section, and the first locking section stops the guide member to prevent the size of the guide member and the limit member 41 from increasing along the first direction, thereby limiting the distance between the first frame 31 and the second frame 32, so that the frame assembly maintains a relatively close distance; at this time, the cleaning cloth will not be tensioned by the roller body because the distance between the two frames is small, and the cleaning cloth is in a relaxed state.

[0053] In the tension adjustment state, the first frame 31 and the second frame 32 need to move away from each other, but the guide member needs to be unlocked from the first locking section. Specifically, the user needs to apply a pressing force to bring the two frames closer together, and the guide member enters the second locking section from the first locking section, and then enters the head end of the second sliding section. At this time, the pressure is released and the two frames are unlocked. The movement of the two frames away from each other will drive the guide member to move along the head end of the second sliding section toward the head end of the first sliding section to increase the size occupied by the entire guide limit assembly in the first direction. When the first frame 31 and the second frame 32 stop moving away from each other, the guide member section stops at the head end of the first sliding section to prevent the size of the guide member and the limit member 41 from further increasing along the first direction, thereby limiting the distance between the first frame 31 and the second frame 32 from being too large. At this time, the cleaning cloth will be tensioned by the roller body due to the large distance between the two frames, and the cleaning cloth is in a tensioned state.

[0054] In at least one embodiment, at the end of the first release stroke, that is, when the guide member moves to the beginning of the second locking section, the first frame 31 and the second frame 32 are in a close state.

[0055] In at least one embodiment, at the end of the second release stroke, that is, when the guide member moves to the beginning of the first locking section, the first frame 31 and the second frame 32 are in a distanced state.

[0056] As one of the specific structural forms, the shape of the slide groove section is roughly heart-shaped, the slide groove section is connected end to end to form a closed loop structure, and the slide groove section has a centroid. The first sliding section is a straight section, the first locking section, the second locking section and the second sliding section are arc sections, the head end of the first sliding section is connected to the tail end of the second sliding section, the tail end of the first sliding section is connected to the head end of the first locking section, the tail end of the first locking section is connected to the head end of the second locking section, and the tail end of the second locking section is connected to the head end of the second sliding section.

[0057] More specifically, the distance between the first locking segment and the centroid is greater than the distance between the first locking segment and the centroid, that is, the movement of the guide along the first locking segment corresponds to the movement of the first frame 31 and the second frame 32 moving away from each other, and the inner arc of the first locking segment faces one side of the centroid. Similarly, the distance between the first end of the second locking segment and the centroid is less than the distance between the second locking segment and the centroid, that is, the movement of the guide along the second locking segment corresponds to the movement of the first frame 31 and the second frame 32 moving toward each other, and the inner arc of the second locking segment is set toward one side of the centroid. Similarly, the inner arc of the second sliding segment also faces one side of the centroid.

[0058] It can be seen that the distance between the first locking section and the second locking section is much smaller than the distance between the first sliding section and the second sliding section. The first locking section and the second locking section are arranged in an arc shape to reduce the interference between the movement of the guide member along the slide groove section and the movement of the two frames, so that the sliding of the guide member is smoother. The second sliding section is arranged in an arc structure to make up for the distance difference between the end of the second locking section and the head end of the first sliding section in the left and right directions perpendicular to the first direction, so that the guide member can smoothly rotate along the second sliding section to the end of the first locking section.

[0059] In some other embodiments, the first sliding section and the second sliding section can be replaced with each other, that is, the first sliding section is an arc section and the second sliding section is a straight section; or, the first sliding section and the second sliding section can both be arc sections or both be straight sections.

[0060] In this embodiment, the slide groove section has an abutting position abutting against the guide member, and the height of the abutting position decreases in sequence along the first sliding section, the first locking section, and the second locking section; the abutting position of the second sliding section gradually rises in the direction close to the first sliding section to be higher than the abutting position of the first sliding section. Specifically, the abutting end may be the bottom surface of the slide groove section, and in some other embodiments, the abutting end may be the side surface of the slide groove section.

[0061] In the above sequence of the first sliding section, the first locking section and the second locking section, the height until the abutment is successively reduced, thereby forming a step surface with a gradually decreasing height between the first sliding section, the first locking section and the second locking section, thereby preventing the guide member from moving from the first locking section to the first sliding section and from the second locking section to the first locking section in the reverse direction. The abutment of the second sliding section gradually rises in the direction close to the first sliding section to a position higher than the abutment of the first sliding section. This arrangement allows the guide member to only move along the head end of the second sliding section to the tail end of the second sliding section and cannot slide in the reverse direction.

[0062] In this embodiment, an elastic member is installed between the first frame and the second frame. In a tensioned adjustment state, the elastic member can provide an elastic driving force for the first frame and the second frame in a direction away from each other; and / or, in a relaxed adjustment state, the elastic member can provide an elastic resistance for the first frame and the second frame in a direction approaching each other.

[0063] Specifically, the elastic member can be a metal spring 312, and the axial direction of the metal spring 312 is parallel to the first direction. In some other embodiments, the elastic member can also be replaced by a gas spring 312 or a hydraulic spring 312. One end of the elastic member abuts against the first frame 31, and the other end abuts against the second frame 32. Specifically, the two ends of the elastic member can be fixed to the first frame 31 and the second frame 32 respectively.

[0064] See again Figure 5In this embodiment, the limiting member 41 is a limiting block, the slide groove section is located on the surface of the limiting block, and the guide member includes a connecting rod, one end of the connecting rod is connected to the first frame or the second frame, and the other end has a guiding portion 421 that cooperates with the slide groove.

[0065] Specifically, the limit block is a square block structure, and the slide groove section is arranged on the upper surface or the lower surface of the limit block. One end of the connecting rod is rotatably connected to the first frame or the second frame. The guide part 421 is perpendicular to the connecting rod, and at least part of the guide part 421 is inserted into the slide groove. Specifically, the connecting rod is connected to the first frame through the mounting seat 313.

[0066] Preferably, the cross section of the guide portion 421 is circular, and the head end of the guide portion 421 inserted into the slide groove section has a circular chamfer to improve the smoothness of the guide portion 421 when sliding along the slide groove section.

[0067] In this embodiment, in the slack adjustment state, the frame assembly has a first pressing stroke and a first releasing stroke, in which the guide moves along a trajectory of the first sliding section head end, the first sliding section tail end, and the first locking section head end in the first releasing stroke, the guide moves along a trajectory of the first locking section head end, the first locking section tail end, and the second locking section head end in the first releasing stroke; and / or, in the tension adjustment state, the frame assembly has a second pressing stroke and a second releasing stroke, in which the guide moves along a trajectory of the second locking section head end, the second locking section tail end, and the second sliding section head end in the second releasing stroke, the guide moves along a trajectory of the second sliding section head end, the second sliding section tail end, and the first locking section head end.
