Description

Technical Field

[0001] This utility model relates to the field of cleaning tools technology, specifically to a mop. Background Technology

[0002] The PVA mop head has strong water absorption, quickly absorbing moisture, oil, hair, and other stains from the floor, leaving the floor dry and without watermarks. However, PVA mops often require a wringer to squeeze out water from the mop head. This wringer is positioned close to the mop head, requiring the user to hold and move it relative to the mop head to squeeze out water. This is not only messy and strenuous, but also inconvenient and negatively impacts the user experience. Utility Model Content

[0003] In view of this, the present invention provides a mop to solve the problem that the current mop spout structure makes it easy to get your hands dirty and is very laborious when squeezing water, resulting in the inconvenience of squeezing water from the sponge cleaning head.

[0004] This utility model provides a mop, including a cleaning head, a mop handle, and a mounting bracket; The mop handle is movably connected to one end of the mounting bracket, and the cleaning head is rotatably connected to the other end of the mounting bracket via a rotating shaft, which extends radially along the mop handle. The cleaning head has a first end face and a second end face along its length. When the cleaning head is rotated relative to the mounting bracket along the rotation axis until the first end face corresponds to the end of the mop handle, the mop handle is driven to move relative to the mounting bracket until the end of the mop handle abuts against the first end face, and the first end face moves closer to the second end face, so that the cleaning head is compressed along its length to expel the water in the cleaning head.

[0005] Beneficial effects: This utility model provides a mop with a movable structure relative to the mounting bracket and a rotatable structure relative to the mounting bracket. When the cleaning head rotates and aligns with the end of the mop handle, the cleaning head can be squeezed out of water by directly compressing it with the mop handle. The water-squeezing operation directly drives the mop handle, which is not only easy to clean hands but also saves effort, improving the convenience for users to squeeze water out of the cleaning head.

[0006] In one optional embodiment, the cleaning head is disposed on a wringer, and the wringer and one of the mounting brackets are provided with the rotating shaft, and the wringer is rotatably connected to the mounting bracket through the rotating shaft. When the wringer is subjected to force and rotates relative to the mounting bracket along the rotation axis, the cleaning head rotates until the first end face corresponds to the end of the mop handle. The mop handle is then driven to move relative to the mounting bracket until the end of the mop handle abuts against the first end face, and the first end face moves closer to the second end face, causing the cleaning head to be compressed along its length on the wringer to expel water from the cleaning head.

[0007] Beneficial effects: The cleaning head is mounted on the wringer frame, which facilitates the rotational connection between the cleaning head and the mounting frame; at the same time, the wringer frame provides a rigid limit for the cleaning head, which facilitates the wringing operation and reset of the cleaning head after wringing.

[0008] In one alternative embodiment, the dewatering rack includes a mounting plate located outside the second end face and abutting against the second end face; When the wringer is subjected to force and rotates relative to the mounting bracket along the rotation axis, the cleaning head rotates until the first end face corresponds to the end of the mop handle. The mop handle is then driven to move relative to the mounting bracket until the end of the mop handle abuts against the first end face, causing the first end face to move closer to the mounting plate, thereby compressing the cleaning head along its length to expel water from the cleaning head.

[0009] Beneficial effects: The mounting plate, located on the outer side of the second end face, provides a supporting position for the cleaning head during squeezing, ensuring the position of the first end face of the cleaning head is fixed during squeezing operations. This allows the first end face of the cleaning head to approach and squeeze towards the first end face, improving squeezing efficiency. Simultaneously, the mounting plate also limits the installation of the cleaning head on the squeezing frame.

[0010] In one optional embodiment, the dewatering rack is further provided with an opening plate, which is disposed opposite to the mounting plate and located outside the first end face, and the opening plate has an opening. When the wringer is subjected to force and rotates relative to the mounting bracket along the rotation axis, the cleaning head rotates until the first end face corresponds to the end of the mop handle. The mop handle is then driven to move relative to the mounting bracket until it passes through the opening and its end abuts against the first end face. This causes the first end face to move closer to the mounting plate, compressing the cleaning head along its length to expel water from the cleaning head.

[0011] Beneficial effects: The wringer rack has an open plate, which allows the mop handle to pass through the opening and abut against the first end face of the cleaning head inside the open plate. This facilitates driving the first end face of the cleaning head towards the mounting plate, so that the first end face moves towards the second end face for wringing. At the same time, the open plate also limits the installation of the cleaning head on the wringer rack.

[0012] In one alternative embodiment, the first end face is provided with an abutment plate, at least a portion of which is located between the opening and the first end face; When the wringer is subjected to force and rotates relative to the mounting bracket along the rotation axis, the cleaning head rotates until the first end face corresponds to the end of the mop handle. The mop handle is then driven to move relative to the mounting bracket until it passes through the opening and its end abuts against the abutment plate. This causes the abutment plate to move closer to the mounting plate, compressing the cleaning head along its length to expel water from the cleaning head.

[0013] Beneficial effects: The abutment plate can be directly driven to abut against the first end face of the cleaning head, so as to increase the force-bearing area of ​​the first end face of the cleaning head, ensure that the cleaning head is compressed as a whole from the first end face to the second end face, and improve the water squeezing efficiency of the cleaning head.

[0014] In one optional embodiment, a positioning hole is provided inside the cleaning head along the length direction, and the wringer includes a positioning shaft, which is inserted into the positioning hole; When the wringer is subjected to force and rotates relative to the mounting bracket along the rotation axis, the cleaning head rotates until the first end face corresponds to the end of the mop handle. The mop handle is then driven to move relative to the mounting bracket until the end of the mop handle abuts against the first end face, and the first end face moves towards the second end face until the positioning shaft extends from the first end face. This causes the cleaning head to be compressed along its length on the wringer to expel water from the cleaning head.

[0015] Beneficial effects: The positioning shaft is inserted into the positioning hole to position the cleaning head and the wringer; at the same time, the positioning shaft can also guide the wringing and resetting of the cleaning head in conjunction with the positioning hole.

[0016] In one optional embodiment, the wringer further includes two connecting plates, which are arranged parallel to the positioning shaft and located on the outside of the cleaning head. One of the connecting plates and the mounting bracket is provided with the rotating shaft, and the side of the connecting plate away from the cleaning head is rotatably connected to the mounting bracket via the rotating shaft.

[0017] Beneficial effects: The connecting plate located on the outside of the cleaning head provides auxiliary positioning for the cleaning head, facilitating the compression and repositioning of the cleaning head.

[0018] In one optional embodiment, the mounting bracket has two connecting arms extending away from the mop handle at one end. A rotating cavity is formed between the two connecting arms. A rotating shaft is disposed on the connecting arms, and the cleaning head is rotatably connected to the two connecting arms via the rotating shaft. The cleaning head is subjected to force and rotates relative to the two connecting arms within the rotating cavity along the rotating shaft until its first end face corresponds to the end of the mop handle.

[0019] Beneficial effect: The two connecting arms extending away from the mop handle form a rotating cavity, thus providing clearance for the cleaning head to rotate.

[0020] In one optional embodiment, when the cleaning head rotates relative to the connecting arm within the rotating cavity along the rotating axis, it has a cleaning state in which the length direction of the cleaning head is perpendicular to the axis of the mop handle and a wringing state in which the length direction of the cleaning head is parallel to the axis of the mop handle. When the cleaning head rotates relative to the connecting arm along the rotation axis until the first end face corresponds to the end of the mop handle, the length direction of the cleaning head is parallel to the axis of the mop handle, and the cleaning head is in a wringing state. At this time, the mop handle is driven to rotate relative to the connecting arm until the end of the mop handle abuts against the first end face, and drives the first end face to move closer to the second end face, so that the cleaning head is compressed along the length direction to expel the water in the cleaning head.

[0021] Beneficial effects: When the cleaning head is in the cleaning state, it facilitates routine cleaning operations; when the cleaning head is rotated to the wringing state, it facilitates wringing operations.

[0022] In one optional embodiment, a positioning device is provided between the wringer and the connecting arm. When the cleaning head rotates relative to the connecting arm along the rotation axis to a cleaning state or a wringing state, the positioning device is adapted to restrict the rotation of the cleaning head relative to the connecting arm.

[0023] Beneficial effect: A positioning device is installed between the wringer and the connecting arm to lock the cleaning head in the cleaning or wringing state, preventing abnormal rotation of the cleaning head.

[0024] In one optional embodiment, the positioning device includes a hinge and a positioning member, one of which is disposed on the wringer and the other on the connecting arm, and the rotating shaft is disposed on the hinge and coaxially disposed with the hinge. When the cleaning head rotates along the rotation axis relative to the connecting arm to a cleaning state or a squeezing state, the positioning member abuts against the hinge member, thereby restricting the rotation of the cleaning head relative to the connecting arm. When the cleaning head rotates along the rotation axis relative to the connecting arm, during the process of switching the cleaning head from a cleaning state to a squeezing state, or during the process of switching the cleaning head from a squeezing state to a cleaning state, the positioning member disengages from the hinge member, thereby releasing the limiting effect between the cleaning head and the connecting arm.

[0025] Beneficial effects: The locking and unlocking of the wringer and the connecting arm are achieved through the engagement and disengagement of the hinge and the positioning parts, thereby limiting and releasing the position of the cleaning head and the connecting arm.

[0026] In one optional embodiment, the hinge member is recessed towards the rotation axis to form a first positioning groove and a second positioning groove, the first positioning groove and the second positioning groove being arranged circumferentially along the hinge member; When the cleaning head rotates along the rotation axis relative to the connecting arm within the rotation cavity to a cleaning state or a squeezing state, the positioning member abuts against the first positioning groove or the second positioning groove, thereby restricting the rotation of the cleaning head relative to the connecting arm. When the cleaning head rotates along the rotation axis relative to the connecting arm within the rotation cavity, during the process of switching the cleaning head from a cleaning state to a squeezing state, or during the process of switching the cleaning head from a squeezing state to a cleaning state, the positioning member disengages from the first positioning groove or the second positioning groove and slides along the surface of the hinge, thereby releasing the limiting relationship between the cleaning head and the connecting arm.

[0027] Beneficial effects: By setting a first positioning groove and a second positioning groove in the hinge, and in conjunction with the abutting action of the positioning member, the cleaning head can be locked in position in the cleaning state or the wringing state.

[0028] In one optional embodiment, the positioning element includes a positioning block, which is movably disposed on the connecting arm; When the cleaning head is subjected to force and rotates relative to the connecting arm within the rotating cavity to a cleaning state or a squeezing state, the positioning block engages with the first positioning groove or the second positioning groove, thereby restricting the rotation of the cleaning head relative to the connecting arm. When the cleaning head is subjected to force and rotates relative to the connecting arm within the rotating cavity, causing the cleaning head to switch from a cleaning state to a squeezing state, or when the cleaning head is subjected to force and switches from a squeezing state to a cleaning state, the positioning block moves away from the first positioning groove or the second positioning groove, thereby disengaging from the first positioning groove or the second positioning groove and sliding along the outer peripheral surface of the hinge, so that the cleaning head is released from the limiting position of the connecting arm.

[0029] Beneficial effects: By using the positioning block in the positioning component to engage with the first positioning groove or the second positioning groove, the cleaning head can be locked in position during cleaning or wringing. The structure is simple and the fit is stable.

[0030] In one optional embodiment, the connecting arm has a limiting groove, the positioning block is movably disposed in the limiting groove, and the positioning member further includes an elastic member disposed in the limiting groove, the elastic member being adapted to drive the positioning block to move toward the hinge member or away from the hinge member. When the cleaning head is subjected to force and rotates relative to the connecting arm within the rotating cavity to a cleaning state or a squeezing state, the elastic element applies energy to move the positioning block closer to the hinge, thereby causing the positioning block to slide into the first positioning groove or the second positioning groove to restrict the rotation of the cleaning head relative to the connecting arm. When the cleaning head is subjected to force and rotates relative to the connecting arm within the rotating cavity, during the process of switching the cleaning head from a cleaning state to a squeezing state, or during the process of switching the cleaning head from a squeezing state to a cleaning state, the hinge presses the positioning block to move away from the hinge, causing the elastic element to store energy in the limiting groove, thereby causing the positioning block to disengage from the first positioning groove or the second positioning groove and slide along the outer peripheral surface of the positioning element, so that the cleaning head is released from the limiting position of the connecting arm.

[0031] Beneficial effects: The limiting groove on the connecting arm provides an installation position for the elastic element; the elastic element in the positioning component is used to realize the extension and retraction adjustment of the positioning block, which is simple in structure and efficient in operation.

[0032] In one optional embodiment, the mounting bracket is further provided with a mounting position, and the mop handle is slidably disposed in the mounting position; When the cleaning head is rotated relative to the mounting bracket along the rotation axis until the first end face corresponds to the end of the mop handle, the mop handle is driven to move in the mounting position along the axis of the mop handle towards the cleaning head until the end of the mop handle abuts against the first end face, and the first end face moves closer to the second end face, so that the cleaning head is compressed along the length direction to expel the water in the cleaning head.

[0033] Beneficial effects: The mounting positions on the mounting bracket provide support for the sliding of the mop handle, thereby guiding the sliding of the mop handle and improving the stability of the cleaning head during the wringing operation.

[0034] In one optional embodiment, a limiting device is provided between the mop handle and the mounting position, the limiting device allowing the mop handle to have a locked state and an unlocked state relative to the mounting position; When the limiting device locks the mop handle to the mounting position, the mop handle is locked to the mounting position, restricting the mop handle from moving towards the cleaning head along the mop handle axis within the mounting position. When the limiting device is unlocked, the mop handle is unlocked from the mounting position. When the mop handle is subjected to force, it is adapted to move towards the cleaning head along the mop handle axis within the mounting position until the end of the mop handle abuts against the first end face, and drives the first end face to move towards the second end face, so that the cleaning head is compressed along the length direction to expel the water in the cleaning head.

[0035] Beneficial effect: A limiting device is installed between the mop handle and the mounting position to lock the position of the mop handle and prevent abnormal sliding of the mop handle.

[0036] In one alternative embodiment, the limiting device includes a grip sleeve that is fitted around the outer periphery of the mounting position and is slidable along the mop handle axis; the mounting bracket has a boss on the side away from the cleaning head, and the grip sleeve has a first position abutting against the boss and a second position away from the boss. When the grip sleeve is in the first position, the limiting device is locked, and the mop handle is locked to the mounting position to restrict the mop handle from moving towards the cleaning head along the mop handle axis within the mounting position. When the grip sleeve slides from the first position away from the boss to the second position, the mop handle is unlocked from the mounting position, the limiting device is unlocked, and the mop handle is adapted to move towards the cleaning head along the mop handle axis within the mounting position until the end of the mop handle abuts against the first end face, and drives the first end face to move towards the second end face, so that the cleaning head is compressed along the length direction to expel water from the cleaning head.

[0037] Beneficial effect: The boss and the grip sleeve create a limiting effect, which limits the sliding of the grip sleeve along the axial direction of the mop handle, so that the grip sleeve can be accurately adjusted to the locked or unlocked position of the mop handle and the mounting position.

[0038] In one optional embodiment, the limiting device further includes a ball bearing movably disposed between the grip sleeve and the mounting position; When the grip sleeve is in the first position, the inner wall of the grip sleeve presses against the ball bearing, causing the ball bearing to abut against the outer wall of the mop handle, thus locking the limiting device and restricting the mop handle from moving towards or away from the cleaning head relative to the mounting position. When the grip sleeve slides from the first position away from the boss to the second position, the inner wall of the grip sleeve stops pressing against the ball bearing, the ball bearing moves away from the outer wall of the mop handle, and the limiting device is unlocked, allowing the mop handle to move towards or away from the cleaning head within the mounting position along the axis of the mop handle.

[0039] Beneficial effects: The limiting device utilizes the contact and disengagement action between the ball bearing and the outer wall of the mop handle to achieve locking and unlocking between the outer periphery of the mop handle and the inner periphery of the mounting position. The structure is simple and the fit is stable.

[0040] In one optional embodiment, the inner surface of the grip sleeve has a first snap-fit ​​position and a second snap-fit ​​position, the diameter of the first snap-fit ​​position being smaller than the diameter of the second snap-fit ​​position; the mounting position has a limiting hole, and the ball is located in the limiting hole; When the grip sleeve is in the first position, the ball bearing is in the first engaging position. The inner wall of the grip sleeve presses against the ball bearing, causing it to pass through the limiting hole and abut against the outer wall of the mop handle, thus locking the limiting device and locking the mop handle to the mounting position. When the grip sleeve slides from the first position to the second position away from the boss, the ball bearing slides from the first engaging position to the second engaging position. The inner wall of the grip sleeve stops pressing against the ball bearing, and the ball bearing moves away from the outer wall of the mop handle. The limiting device is unlocked, thus allowing the mop handle to move within the mounting position along the axis of the mop handle towards the rotating cavity of the mounting bracket.

[0041] Beneficial effects: The limiting hole in the mounting position provides an installation position for the ball bearing; the diameter of the first locking position is smaller than the diameter of the second locking position, so that when the grip sleeve slides to the first locking position and is on the outside of the ball bearing, it abuts and squeezes against the ball bearing, and when it slides to the second locking position and is on the outside of the ball bearing, it moves away from the ball bearing, thereby realizing the locking and unlocking of the outer periphery of the mop handle and the inner periphery of the mounting position.

[0042] In one optional embodiment, the outer wall of the mounting position is provided with a blocking protrusion at the end away from the cleaning head, and the inner wall of the grip sleeve is provided with a blocking step in the direction close to the first snap-fit ​​position. A reset member is provided between the blocking protrusion and the blocking step. When the grip sleeve is slid from the first position to the second position away from the boss, the reset member stores energy; when the grip sleeve is stopped, the reset member releases energy, thereby causing the grip sleeve to reset from the second position to the first position.

[0043] Beneficial effects: The limiting cooperation between the anti-protrusion and the anti-step prevents the grip sleeve from dislodging from the installation position; at the same time, the reset component set between the anti-protrusion and the anti-step enables the grip sleeve to automatically reset from the second position to the first position, improving the convenience of the squeezing operation.

[0044] In one optional embodiment, two connecting plates are symmetrically arranged on the wringer, the connecting plates are arranged along the length direction of the cleaning head, and the mounting bracket is hinged to the connecting plates.

[0045] Beneficial effects: The symmetrically arranged connecting plates on the dewatering rack facilitate the hinged connection between the mounting bracket and the dewatering rack.

[0046] In one alternative embodiment, the cleaning head has two cleaning surfaces, which are adapted to switch between when the cleaning head is rotated.

[0047] Beneficial effect: The cleaning head has two cleaning surfaces to improve its lifespan. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0054] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0055] The following is combined Figures 1-8 The following describes embodiments of the present invention.

[0056] According to an embodiment of the present invention, a mop is provided, such as... Figure 1 , Figure 2 As shown, it includes: a cleaning head 100, a mop handle 200, a mounting bracket 300, and a rotating shaft 400.

[0057] One end of the mop handle 200 is movably connected to the mounting bracket 300, and the other end of the cleaning head 100 is rotatably connected to the mounting bracket 300 via a rotating shaft 400, which extends radially along the mop handle 200. The cleaning head 100 has a first end face 110 and a second end face 120 along its length. When the cleaning head 100 is subjected to force and rotates relative to the mounting bracket 300 along the rotating shaft 400 until the first end face 110 corresponds to the end of the mop handle 200, the mop handle 200 is driven to move relative to the mounting bracket 300 until the end of the mop handle 200 abuts against the first end face 110, and drives the first end face 110 to move closer to the second end face 120, so that the cleaning head 100 is compressed along its length to expel the water in the cleaning head 100.

[0058] In the above embodiment, the mop handle 200 is configured as a movable structure relative to the mounting bracket 300, and the cleaning head 100 is configured as a rotatable structure relative to the mounting bracket 300. When the cleaning head 100 rotates to correspond with the end of the mop handle 200, the cleaning head 100 can be squeezed out of water by directly compressing it with the mop handle 200. The water squeezing operation directly drives the mop handle 200, which is not only easy to clean hands but also saves effort, improving the convenience for users to squeeze water out of the cleaning head 100.

[0059] Specifically, the rotating shaft 400 extends radially along the mop handle 200 so that the mop handle 200 can rotate to an axially corresponding position relative to the mounting bracket 300. The first end face 110 and the second end face 120 of the cleaning head 100 are located at opposite ends along its length, wherein the second end face 120 is a fixed end and the first end face 110 is a movable end that can move relative to the second end face 120. When the cleaning head 100 is rotated relative to the mounting bracket 300 along the rotating shaft 400 until the first end face 110 corresponds to the end of the mop handle 200, the first end face 110 is closer to the end of the mop handle 200 while the second end face 120 is farther away from the end of the mop handle 200. At this time, the user places the second end face 120 of the cleaning head 100 against the ground or the bottom of the mop bucket, and manually drives the mop handle 200 to move relative to the mounting bracket 300 so that it squeezes the first end face 110 of the cleaning head 100, so that the first end face 110 moves closer to the second end face 120 to generate a squeezing effect, thereby performing the water squeezing operation.

[0060] Furthermore, when the cleaning head 100 is rotated relative to the mounting bracket 300 along the rotation axis 400 until the first end face 110 corresponds to the end of the mop handle 200, the user can hold the mop handle 200 and the second end face 120 of the cleaning head 100 against the ground or the bottom of the mop bucket to drive the cleaning head 100 to rotate, or manually apply force to the cleaning head 100 to make it rotate.

[0061] Furthermore, the cleaning head 100 is configured as a cotton cleaning head.

[0062] In some embodiments, such as Figure 1 , Figure 3 As shown, the cleaning head 100 is mounted on the wringer 500. One of the wringer 500 and the mounting bracket 300 is provided with a rotating shaft 400. The wringer 500 is rotatably connected to the mounting bracket 300 through the rotating shaft 400. When the wringer 500 is subjected to force, it rotates relative to the mounting bracket 300 along the rotating shaft 400, and drives the cleaning head 100 to rotate until the first end face 110 corresponds to the end of the mop handle 200. When the mop handle 200 is driven to move relative to the mounting bracket 300 until the end of the mop handle 200 abuts against the first end face 110, and drives the first end face 110 to move closer to the second end face 120, so that the cleaning head 100 is compressed along the length direction on the wringer 500 to discharge the water in the cleaning head 100.

[0063] In the above embodiment, the cleaning head 100 is disposed on the wringer 500 to facilitate the rotatable connection between the cleaning head 100 and the mounting bracket 300; at the same time, the wringer 500 provides a rigid limit for the cleaning head 100 to facilitate the wringing operation of the cleaning head 100 and its reset after wringing.

[0064] Specifically, the rotating shaft 400 is mounted on the wringer 500, and the mounting bracket 300 has a rotating mounting position corresponding to the rotating shaft 400 for rotational connection. The cleaning head 100 is a flexible structure of a sponge cleaning head, which is inconvenient to directly rotate and connect with the mounting bracket 300. The wringer 500 provides a mounting position for the cleaning head 100, thus facilitating a rotational connection between the cleaning head 100 and the mounting bracket 300. At the same time, the wringer 500 is a frame structure, providing good rigid restraint for the cleaning head 100. The wringer 500 can serve as a restraining basis for both squeezing and resetting of the cleaning head 100.

[0065] In some embodiments, such as Figure 1 , Figure 3 As shown, the wringer 500 includes a mounting plate 510, which is located outside the second end face 120 and abuts against the second end face 120. When the wringer 500 is subjected to force, it rotates relative to the mounting frame 300 along the rotation axis 400, and drives the cleaning head 100 to rotate until the first end face 110 corresponds to the end of the mop handle 200. When the mop handle 200 is driven to move relative to the mounting frame 300 until the end of the mop handle 200 abuts against the first end face 110, and drives the first end face 110 to move closer to the mounting plate 510, so that the cleaning head 100 is compressed along the length direction to discharge the water in the cleaning head 100.

[0066] In the above embodiment, the mounting plate 510 is located outside the second end face 120, providing a support position for the cleaning head 100 during water squeezing, ensuring that the position of the first end face 110 of the cleaning head 100 is fixed during the water squeezing operation, so that the first end face 110 of the cleaning head 100 can move closer to the first end face 110 for squeezing, thereby improving the water squeezing efficiency. At the same time, the mounting plate 510 also limits the installation of the cleaning head 100 on the water squeezing frame 500.

[0067] Specifically, the mounting plate 510 is located outside the second end face 120. When the cleaning head 100 rotates to the point where the first end face 110 corresponds to the end of the mop handle 200, the mounting plate 510 can directly abut against the ground or the bottom of the mop bucket, thereby ensuring that the position of the first end face 110 of the cleaning head 100 is fixed during the wringing operation. At the same time, the mounting plate 510 is located outside the second end face 120 to limit the installation of the second end face 120 of the cleaning head 100 on the wringing frame 500.

[0068] Furthermore, in this embodiment, the mounting plate 510 is integrally formed on the end of the main structure of the dewatering rack 500 near the second end face 120. As an alternative implementation, the mounting plate 510 can be detachably connected to the end of the main structure of the dewatering rack 500 near the second end face 120, which facilitates mold manufacturing.

[0069] In some embodiments, such as Figure 1 , Figure 3 As shown, the wringer 500 is also provided with an opening plate 520. The opening plate 520 is disposed opposite to the mounting plate 510 and located outside the first end face 110. An opening 521 is provided on the opening plate 520. When the wringer 500 is subjected to force, it rotates relative to the mounting frame 300 along the rotation axis 400, and drives the cleaning head 100 to rotate until the first end face 110 corresponds to the end of the mop handle 200. When the mop handle 200 is driven to move relative to the mounting frame 300 until it passes through the opening 521 and its end abuts against the first end face 110, it drives the first end face 110 to move closer to the mounting plate 510, so that the cleaning head 100 is compressed along the length direction to discharge the water in the cleaning head 100.

[0070] In the above embodiment, the wringer 500 is provided with an opening plate 520 having an opening 521, which facilitates the mop handle 200 passing through the opening 521 and abutting against the first end face 110 of the cleaning head 100 inside the opening plate 520. This facilitates driving the first end face 110 of the cleaning head 100 closer to the mounting plate 510, so that the first end face 110 moves closer to the second end face 120 for wringing. At the same time, the opening plate 520 also limits the installation of the cleaning head 100 on the wringer 500.

[0071] Specifically, the opening plate 520, located outside the first end face 110, limits the installation of the first end face 110 of the cleaning head 100 on the wringer 500. The opening 521 of the opening plate 520 is contoured to the mop handle 200, with the inner diameter of the opening 521 larger than the outer diameter of the mop handle 200 to facilitate the passage of the mop handle 200 through the opening 521. In this embodiment, the mop handle 200 is configured as a cylindrical structure, and the opening 521 is constructed as a circular opening groove.

[0072] Furthermore, in this embodiment, the opening plate 520 is integrally formed on the end of the main structure of the dewatering rack 500 near the first end face 110. As an alternative implementation, the opening plate 520 can be detachably connected to the end of the main structure of the dewatering rack 500 near the first end face 110, which facilitates mold manufacturing.

[0073] In some embodiments, such as Figure 1 , Figure 3As shown, the first end face 110 is provided with an abutment plate 600, at least a portion of which is located between the opening 521 and the first end face 110. The wringer 500 is subjected to force and rotates relative to the mounting bracket 300 along the rotation axis 400, and drives the cleaning head 100 to rotate until the first end face 110 corresponds to the end of the mop handle 200. The mop handle 200 is driven to move relative to the mounting bracket 300 to pass through the opening 521 and its end abuts against the abutment plate 600, and drives the abutment plate 600 to move closer to the mounting plate 510, so that the cleaning head 100 is compressed along the length direction to discharge the water in the cleaning head 100.

[0074] In the above embodiment, the abutment plate 600 can be directly driven to abut against the first end face 110 of the cleaning head 100, so as to increase the force-bearing area of ​​the first end face 110 of the cleaning head 100, ensure that the cleaning head 100 is compressed as a whole from the first end face 110 to the second end face 120, and improve the water squeezing efficiency of the cleaning head 100.

[0075] Specifically, the abutment plate 600 is a rigid structure that connects to and can move synchronously with the first end face 110 of the cleaning head 100. The diameter of the abutment plate 600 is larger than the diameter of the opening 521, and can be designed to be as large as possible so that the dimensions of the abutment plate 600 are close to the first end face 110 of the cleaning head 100, thereby maximizing the force-bearing area of ​​the first end face 110.

[0076] In some embodiments, such as Figure 3 , Figure 4 As shown, a positioning hole 130 is provided in the cleaning head 100 along its length direction. The wringer 500 includes a positioning shaft 530, which is inserted into the positioning hole 130. When the wringer 500 is subjected to force, it rotates relative to the mounting bracket 300 along the rotation shaft 400, and drives the cleaning head 100 to rotate until the first end face 110 corresponds to the end of the mop handle 200. When the mop handle 200 is driven to move relative to the mounting bracket 300 until the end of the mop handle 200 abuts against the first end face 110, and drives the first end face 110 to move towards the second end face 120 until the positioning shaft 530 extends out from the first end face 110, so that the cleaning head 100 is compressed along its length direction on the wringer 500 to discharge the water in the cleaning head 100.

[0077] In the above embodiment, the positioning shaft 530 is inserted into the positioning hole 130 to position and install the cleaning head 100 and the wringer 500; at the same time, the positioning shaft 530 can also cooperate with the positioning hole 130 to guide the wringing and resetting of the cleaning head 100.

[0078] Specifically, the positioning hole 130 provided along the length direction inside the cleaning head 100 is a cleaning head strip hole with a length equivalent to the length of the cleaning head 100; the positioning shaft 530 is fixedly provided at at least one end of the wringer 500.

[0079] In some embodiments, such as Figure 3 , Figure 4 As shown, the wringer 500 also includes two connecting plates 540. The connecting plates 540 are arranged parallel to the positioning shaft 530 and are located on the outside of the cleaning head 100. One of the connecting plates 540 and the mounting bracket 300 is provided with a rotating shaft 400. The side of the connecting plate 540 away from the cleaning head 100 is rotatably connected to the mounting bracket 300 through the rotating shaft 400.

[0080] In the above embodiment, the connecting plate 540 disposed on the outside of the cleaning head 100 forms an auxiliary positioning for the cleaning head 100, so as to provide auxiliary guidance for the compression and resetting of the cleaning head 100.

[0081] Specifically, the two ends of the connecting plate 540 are fixedly connected to the mounting plate 510 and the opening plate 520, respectively, and the two connecting plates 540 are symmetrically arranged relative to the positioning shaft 530. The end of the positioning shaft 530 is fixedly connected to the mounting plate 510.

[0082] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 As shown, the mounting bracket 300 has two connecting arms 310 extending away from the mop handle 200 at one end. A rotating cavity 320 is formed between the two connecting arms 310. A rotating shaft 400 is disposed on the connecting arms 310, and the cleaning head 100 is rotatably connected to the two connecting arms 310 through the rotating shaft 400. When the cleaning head 100 is subjected to force, it rotates relative to the two connecting arms 310 along the rotating shaft 400 within the rotating cavity 320 until the first end face 110 corresponds to the end of the mop handle 200.

[0083] In the above embodiment, two connecting arms 310 extending away from the mop handle 200 are used to form a rotating cavity 320, thereby providing clearance space for the rotation of the cleaning head 100.

[0084] Specifically, the two connecting arms 310 on the mounting bracket 300 are arranged opposite each other to form a U-shaped rotating cavity 320. There are two rotating shafts 400, one between each of the two connecting arms 310 and the wringer 500 on which the cleaning head 100 is mounted.

[0085] In some embodiments, such as Figure 1 , Figure 2 , Figure 3As shown, when the cleaning head 100 rotates relative to the connecting arm 310 along the rotation shaft 400 within the rotation cavity 320, it has a cleaning state where the length direction of the cleaning head 100 is perpendicular to the axis of the mop handle 200, and a squeezing state where the length direction of the cleaning head 100 is parallel to the axis of the mop handle 200. When the cleaning head 100 rotates relative to the connecting arm 310 along the rotation shaft 400 until the first end face 110 corresponds to the end of the mop handle 200, the length direction of the cleaning head 100 is parallel to the axis of the mop handle 200, and the cleaning head 100 is in the squeezing state. At this time, the mop handle 200 is driven to rotate relative to the connecting arm 310 until the end of the mop handle 200 abuts against the first end face 110, and drives the first end face 110 to move closer to the second end face 120, so that the cleaning head 100 is compressed along its length to discharge the water in the cleaning head 100.

[0086] In the above embodiments, the cleaning head 100 is in a cleaning state to facilitate routine cleaning operations; the cleaning head 100 is rotated to a wringing state to facilitate wringing operations.

[0087] Specifically, when the cleaning head 100 rotates relative to the connecting arm 310 along the rotation axis 400 until the first end face 110 corresponds to the end of the mop handle 200, the axis of the cleaning head 100 is collinear with the axis of the mop handle 200, and the cleaning head 100 is in a wringing state.

[0088] In some embodiments, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a positioning device 700 is provided between the wringer 500 and the connecting arm 310. When the cleaning head 100 rotates along the rotation shaft 400 relative to the connecting arm 310 to the cleaning state or the wringing state, the positioning device 700 is adapted to restrict the rotation of the cleaning head 100 relative to the connecting arm 310.

[0089] In the above embodiment, a positioning device 700 is provided between the wringer 500 and the connecting arm 310 to lock the position of the cleaning head 100 in the cleaning state or the wringing state, so as to prevent the cleaning head 100 from rotating abnormally.

[0090] Specifically, there are two positioning devices 700, one at each of the corresponding positions where the two connecting arms 310 are connected to the wringer 500.

[0091] Furthermore, the positioning device 700 includes, but is not limited to, mechanical locks, electronic locks, etc.

[0092] In some embodiments, such as Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the positioning device 700 includes a hinge 710 and a positioning member 720. One of the hinge 710 and the positioning member 720 is located on the wringer 500, and the other is located on the connecting arm 310. The rotating shaft 400 is located on the hinge 710 and is coaxially arranged with the hinge 710. When the cleaning head 100 rotates along the rotating shaft 400 relative to the connecting arm 310 to the cleaning state or the wringing state, the positioning member 720 abuts against the hinge 710 to restrict the rotation of the cleaning head 100 relative to the connecting arm 310. When the cleaning head 100 rotates along the rotating shaft 400 relative to the connecting arm 310, during the process of switching the cleaning head 100 from the cleaning state to the wringing state, or during the process of switching the cleaning head 100 from the wringing state to the cleaning state, the positioning member 720 disengages from the hinge 710, thereby releasing the restriction between the cleaning head 100 and the connecting arm 310.

[0093] In the above embodiments, the locking and unlocking between the wringer 500 and the connecting arm 310 are achieved by the abutting engagement and disengagement of the hinge 710 and the positioning member 720, thereby achieving the limiting and releasing of the cleaning head 100 and the connecting arm 310.

[0094] Specifically, the hinge 710 is located on the outside of the wringer 500, and two hinges 710 are symmetrically arranged on the outside of the wringer 500. The positioning member 720 is located inside the connecting arm 310, and correspondingly, one set of positioning members 720 is provided in each connecting arm 310.

[0095] Furthermore, the contact between the positioning member 720 and the hinge member 710 can be achieved through friction, or through the cooperation of the limiting groove and the limiting protrusion.

[0096] In some embodiments, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the hinge 710 has a first positioning groove 711 and a second positioning groove 712 recessed towards the rotation axis 400. The first positioning groove 711 and the second positioning groove 712 are arranged circumferentially along the hinge 710. When the cleaning head 100 rotates relative to the connecting arm 310 in the rotation cavity 320 along the rotation axis 400 to a cleaning state or a squeezing state, the positioning member 720 abuts against the first positioning groove 711 or the second positioning groove 712, thereby restricting the rotation of the cleaning head 100 relative to the connecting arm 310. When the cleaning head 100 rotates relative to the connecting arm 310 in the rotation cavity 320 along the rotation axis 400, during the process of switching the cleaning head 100 from the cleaning state to the squeezing state, or during the process of switching the cleaning head 100 from the squeezing state to the cleaning state, the positioning member 720 disengages from the first positioning groove 711 or the second positioning groove 712 and slides along the surface of the hinge 710, so that the cleaning head 100 and the connecting arm 310 are released from restriction.

[0097] In the above embodiments, a first positioning groove 711 and a second positioning groove 712 are provided in the hinge member 710. With the abutment action of the positioning member 720, the position of the cleaning head 100 can be locked in the cleaning state or the wringing state.

[0098] Specifically, the opening direction of the first positioning groove 711 is consistent with the thickness direction of the cleaning head 100, and two are symmetrically arranged along the thickness direction of the cleaning head 100; the opening direction of the second positioning groove 712 is consistent with the length direction of the cleaning head 100, and it is located between the two first positioning grooves 711. The first positioning grooves 711 and the second positioning grooves 712 are distributed at a 90° interval.

[0099] Furthermore, when the cleaning head 100 is in the cleaning state, the positioning member 720 abuts against one of the first positioning grooves 711; when the cleaning head 100 is in the wringing state, the positioning member 720 abuts against the second positioning groove 712.

[0100] In some embodiments, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the positioning member 720 includes a positioning block 721, which is movably mounted on the connecting arm 310. When the cleaning head 100 is subjected to force and rotates relative to the connecting arm 310 within the rotating cavity 320 to a cleaning state or a squeezing state, the positioning block 721 engages with the first positioning groove 711 or the second positioning groove 712, thereby restricting the rotation of the cleaning head 100 relative to the connecting arm 310. When the cleaning head 100 is subjected to force and rotates relative to the connecting arm 310 within the rotating cavity 320, causing the cleaning head 100 to switch from a cleaning state to a squeezing state, or when the cleaning head 100 is subjected to force and switches from a squeezing state to a cleaning state, the positioning block 721 moves away from the first positioning groove 711 or the second positioning groove 712, thereby disengaging from the first positioning groove 711 or the second positioning groove 712 and sliding along the outer peripheral surface of the hinge member 710, so that the cleaning head 100 is released from the limiting position of the connecting arm 310.

[0101] In the above embodiments, the positioning block 721 in the positioning member 720 is engaged with the first positioning groove 711 or the second positioning groove 712 to lock the position of the cleaning head 100 in the cleaning state or the wringing state. The structure is simple and the fit is stable.

[0102] Specifically, the positioning block 721 is movably mounted on the connecting arm 310 through elastic elements, telescopic rods and other structures, so as to realize the force application, locking and resetting of the positioning block 721 to the first positioning groove 711 or the second positioning groove 712.

[0103] In some embodiments, such as Figure 5 , Figure 6 As shown, the connecting arm 310 has a limiting groove 311, and the positioning block 721 is movably disposed within the limiting groove 311. The positioning member 720 also includes an elastic member 722 disposed within the limiting groove 311. The elastic member 722 is adapted to drive the positioning block 721 to move towards or away from the hinge member 710. When the cleaning head 100 is subjected to force and rotates relative to the connecting arm 310 within the rotating cavity 320 to a cleaning state or a squeezing state along the rotation axis 400, the elastic member 722 applies force to move the positioning block 721 towards the hinge member 710, thereby causing the positioning block 721 to slide into the first positioning groove 711 or the second positioning groove 712 to limit the cleaning. The head 100 rotates relative to the connecting arm 310. When the cleaning head 100 is subjected to force and rotates relative to the connecting arm 310 within the rotating cavity 320 along the rotating shaft 400, the cleaning head 100 switches from the cleaning state to the squeezing state, or the cleaning head 100 switches from the squeezing state to the cleaning state, the hinge 710 presses the positioning block 721 to move away from the hinge 710, causing the elastic element 722 to store energy in the limiting groove 311, thereby causing the positioning block 721 to disengage from the first positioning groove 711 or the second positioning groove 712 and slide along the outer peripheral surface of the positioning element 720, so that the cleaning head 100 is released from the limiting position of the connecting arm 310.

[0104] In the above embodiment, the limiting groove 311 on the connecting arm 310 provides an installation position for the elastic element 722; the elastic element 722 in the positioning element 720 is used to realize the extension and retraction adjustment of the positioning block 721, which is simple in structure and efficient in operation.

[0105] Specifically, the hinge 710 presses the positioning block 721 to move away from the hinge 710, so that the elastic element 722 stores energy in the limiting groove 311. After the cleaning head 100 is adjusted to the position, the elastic element 722 releases energy, resets, slides into the first positioning groove 711 or the second positioning groove 712 and engages with it, thereby realizing the limiting and locking of the cleaning head 100 relative to the mounting bracket 300.

[0106] Furthermore, the elastic element 722 is configured as a spring.

[0107] Furthermore, the mounting frame 300 is formed by assembling two frame parts, with a mounting cavity formed between the two frame parts. The limiting groove 311 is provided in the mounting cavity and is formed by a plate integrally formed on the inner wall of the frame. At the same time, the elastic element 722 is provided in the mounting cavity, and one end of the positioning block 721 abuts or connects with the elastic element 722, while the other end extends out of the mounting cavity and engages with the first positioning groove 711 or the second positioning groove 712.

[0108] In some embodiments, such as Figure 3As shown, the mounting bracket 300 is also provided with a mounting position 330, and the mop handle 200 is slidably mounted in the mounting position 330. When the cleaning head 100 is subjected to force and rotates relative to the mounting bracket 300 along the rotation axis 400 until the first end face 110 corresponds to the end of the mop handle 200, the mop handle 200 is driven to move in the mounting position 330 along the axis of the mop handle 200 towards the cleaning head 100 until the end of the mop handle 200 abuts against the first end face 110, and drives the first end face 110 to move closer to the second end face 120, so that the cleaning head 100 is compressed along the length direction to discharge the water in the cleaning head 100.

[0109] In the above embodiment, the mounting position 330 provided on the mounting bracket 300 provides a support position for the sliding of the mop handle 200, so as to guide the sliding of the mop handle 200 and improve the stability of the wringing operation of the cleaning head 100.

[0110] Specifically, the mounting position 330 of the mounting bracket 300 is set as a cylindrical structure with a hollow interior; the mop handle 200 passes through the sliding mounting position 330, so that it can slide relative to the mounting position 330 to realize the wringing operation of the cleaning head 100.

[0111] In some embodiments, such as Figure 3 , Figure 7 , Figure 8 As shown, a limiting device 800 is provided between the mop handle 200 and the mounting position 330. The limiting device 800 allows the mop handle 200 to have a locked state and an unlocked state relative to the mounting position 330. When the limiting device 800 keeps the mop handle 200 and the mounting position 330 locked, the mop handle 200 and the mounting position 330 are locked to restrict the mop handle 200 from moving towards the cleaning head 100 along the axis of the mop handle 200 within the mounting position 330. When the limiting device 800 is unlocked, the mop handle 200 and the mounting position 330 are unlocked. When the mop handle 200 is subjected to force, it is suitable to move towards the cleaning head 100 along the axis of the mop handle 200 within the mounting position 330 until the end of the mop handle 200 abuts against the first end face 110 and drives the first end face 110 to move closer to the second end face 120, so that the cleaning head 100 is compressed along its length to expel the water in the cleaning head 100.

[0112] In the above embodiment, a limiting device 800 is provided between the mop handle 200 and the mounting position 330 to lock the position of the mop handle 200 and prevent the mop handle 200 from sliding abnormally.

[0113] Specifically, the limiting device 800 is set along the outer periphery of the mop handle 200 or the inner periphery of the mounting position 330, thereby realizing the locking and unlocking of the outer periphery of the mop handle 200 and the inner periphery of the mounting position 330.

[0114] In some embodiments, such as Figure 3 , Figure 7 , Figure 8 As shown, the limiting device 800 includes a grip sleeve 810, which is fitted around the outer periphery of the mounting position 330 and can slide along the axial direction of the mop handle 200. A boss 340 is provided on the side of the mounting bracket 300 away from the cleaning head 100. The grip sleeve 810 has a first position abutting against the boss 340 and a second position away from the boss 340. When the grip sleeve 810 is in the first position, the limiting device 800 is locked, and the mop handle 200 is locked to the mounting position 330 to restrict the mop handle 200 from moving along the axial direction of the mop handle 200 within the mounting position 330. The mop handle 200 moves toward the cleaning head 100; when the grip sleeve 810 slides from the first position toward the second position away from the boss 340, the mop handle 200 is unlocked from the mounting position 330, the limiting device 800 is in the unlocked state, and the mop handle 200 is adapted to move along the axis of the mop handle 200 toward the cleaning head 100 within the mounting position 330 until the end of the mop handle 200 abuts against the first end face 110, and drives the first end face 110 toward the second end face 120, so that the cleaning head 100 is compressed along the length direction to discharge the water in the cleaning head 100.

[0115] In the above embodiment, the boss 340 and the grip sleeve 810 provide a limiting effect, which limits the grip sleeve 810 to slide along the axial direction of the mop handle 200, so that the grip sleeve 810 can be accurately adjusted to the locked or unlocked position of the mop handle 200 and the mounting position 330.

[0116] Specifically, the grip sleeve 810 is configured as a cylindrical structure and is hollow. The protruding structure on the outer periphery of the mounting bracket 300 forms a boss 340. The end face of the boss 340 is aligned with the end face of the grip sleeve 810 to achieve contact between the grip sleeve 810 and the boss 340.

[0117] In some embodiments, such as Figure 3 , Figure 7 , Figure 8 As shown, the limiting device 800 also includes a ball bearing 820 movably disposed between the grip sleeve 810 and the mounting position 330. When the grip sleeve 810 is in the first position, the inner wall of the grip sleeve 810 presses against the ball bearing 820, causing the ball bearing 820 to abut against the outer wall of the mop handle 200, thus locking the limiting device 800 and restricting the mop handle 200 from moving towards or away from the cleaning head 100 relative to the mounting position 330. When the grip sleeve 810 slides from the first position away from the boss 340 to the second position, the inner wall of the grip sleeve 810 stops pressing against the ball bearing 820, the ball bearing 820 moves away from the outer wall of the mop handle 200, and the limiting device 800 is unlocked, thereby allowing the mop handle 200 to move towards or away from the cleaning head 100 within the mounting position 330 along the axis of the mop handle 200.

[0118] In the above embodiments, the limiting device 800 utilizes the contact and disengagement action between the ball bearing 820 and the outer wall of the mop handle 200 to achieve locking and unlocking between the outer periphery of the mop handle 200 and the inner periphery of the mounting position 330. The structure is simple and the fit is stable.

[0119] Specifically, multiple balls 820 are arranged circumferentially along the outer wall of the mounting position 330, and multiple circular grooves are arranged circumferentially on the outer wall of the mop handle 200 corresponding to the balls 820. When the grip sleeve 810 is in the first position, the inner wall of the grip sleeve 810 presses against the balls 820, causing the balls 820 to abut against the circular grooves on the outer wall of the mop handle 200, thus locking the limiting device 800. When the grip sleeve 810 slides from the first position to the second position away from the boss 340, the inner wall of the grip sleeve 810 stops pressing against the balls 820, the balls 820 move away from the circular grooves on the outer wall of the mop handle 200, and the limiting device 800 is unlocked.

[0120] In some embodiments, such as Figure 3 , Figure 7 , Figure 8 As shown, the inner surface of the grip sleeve 810 has a first locking position 811 and a second locking position 812, the diameter of the first locking position 811 being smaller than the diameter of the second locking position 812; the mounting position 330 has a limiting hole 331, and the ball bearing 820 is located within the limiting hole 331; when the grip sleeve 810 is in the first position, the ball bearing 820 is located in the first locking position 811, and the inner wall of the grip sleeve 810 presses against the ball bearing 820, causing the ball bearing 820 to pass through the limiting hole 331 and abut against the outer wall of the mop handle 200, thus locking the limiting device 800. This locks the mop handle 200 to the mounting position 330. When the grip sleeve 810 slides from the first position to the second position away from the boss 340, the ball bearing 820 slides from the first locking position 811 to the second locking position 812. The inner wall of the grip sleeve 810 stops pressing the ball bearing 820, and the ball bearing 820 moves away from the outer wall of the mop handle 200. The limiting device 800 is in the unlocked state, which makes the mop handle 200 suitable for moving in the mounting position 330 along the axis of the mop handle 200 towards the rotating cavity 320 of the mounting bracket 300.

[0121] In the above embodiment, the limiting hole 331 opened in the mounting position 330 provides an installation position for the ball bearing 820; the diameter of the first locking position 811 is smaller than the diameter of the second locking position 812, so that the grip sleeve 810 can slide to the first locking position 811 when it is outside the ball bearing 820 and abut against the ball bearing 820, and slide to the second locking position 812 when it is outside the ball bearing 820 and move away from the ball bearing 820, thereby realizing the locking and unlocking of the outer periphery of the mop handle 200 and the inner periphery of the mounting position 330.

[0122] Specifically, the ball 820 is embedded in the limiting hole 331, and the ball 820 has a certain friction with the hole wall of the limiting hole 331, so that the ball 820 can move relative to the limiting hole 331 without dislodging from the limiting hole 331.

[0123] In some embodiments, such as Figure 3 , Figure 7 , Figure 8 As shown, the outer wall of the mounting position 330 is provided with a stop protrusion 332 at the end away from the cleaning head 100, and the inner wall of the grip sleeve 810 is provided with a stop step 813 near the first snap-fit ​​position 811. A reset member is provided between the stop protrusion 332 and the stop step 813. When the grip sleeve 810 is driven to slide from the first position to the second position away from the protrusion 340, the reset member stores energy. When the grip sleeve 810 is stopped, the reset member releases energy, thereby driving the grip sleeve 810 to reset from the second position to the first position.

[0124] In the above embodiment, the limiting cooperation between the blocking protrusion 332 and the blocking step 813 prevents the grip sleeve 810 from disengaging from the installation position 330; at the same time, the reset member set between the blocking protrusion 332 and the blocking step 813 enables the grip sleeve 810 to automatically reset from the second position to the first position, improving the convenience of the squeezing operation.

[0125] Specifically, the abutment protrusion 332 is provided on the outer wall periphery of the mounting position 330 at the end away from the cleaning head 100, and is configured as a snap-fit ​​structure that can move relative to the main structure of the mounting position 330, facilitating assembly with the grip sleeve 810. The abutment step 813 is provided on the inner wall periphery of the grip sleeve 810.

[0126] Furthermore, the reset member is not shown in the figure, and it abuts between the abutting protrusion 332 and the abutting step 813.

[0127] In some embodiments, such as Figure 3 As shown, two connecting plates 540 are symmetrically arranged on the wringer 500. The connecting plates 540 are arranged along the length of the cleaning head 100, and the mounting bracket 300 is hinged to the connecting plates 540.

[0128] In the above embodiment, the connecting plate 540 symmetrically arranged on the dewatering rack 500 is hinged to facilitate the installation of the bracket 300 and the dewatering rack 500.

[0129] Specifically, the two ends of the connecting plate 540 are fixedly connected to the mounting plate 510 and the opening plate 520, respectively.

[0130] In some embodiments, such as Figure 1 As shown, the cleaning head 100 has two cleaning surfaces 140, and the two cleaning surfaces 140 can be switched when the cleaning head 100 rotates.

[0131] In the above embodiment, two cleaning surfaces 140 are provided on the cleaning head 100 to improve the service life of the cleaning head 100.

[0132] Specifically, when the cleaning head 100 is in the cleaning state, it can be cleaned using one of the cleaning surfaces 140. After the cleaning head 100 is rotated 90°, the first end face 110 is aligned with the end of the mop handle 200 to adjust it to the wringing state. Continuing to rotate 90° will put the cleaning head 100 in another cleaning state, at which time it can be cleaned using the other cleaning surface 140.

[0133] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
