Description

Technical Field

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

[0002] Current push-type mops use a wringer attached to the mop handle to dehydrate the sponge on the mop head. Specifically, the wringer has a cleaning channel that mimics the cross-section of the mop head and includes a wringing nozzle. When the user moves the wringer along the mop handle, the mop head inserts into the cleaning channel through the wringing nozzle, and the sponge on it is squeezed or scraped by the side walls of the cleaning channel, thus dehydrating the sponge. However, the current wringer design is flawed, making it unable to effectively wring out sponges of different sizes, thus impacting the user experience. Utility Model Content

[0003] In view of this, this utility model provides a mop wringer to solve the problem that current wringer designs are unreasonable and cannot handle the wringing of sponges of different sizes. Simultaneously, this utility model also provides a mop.

[0004] In a first aspect, this utility model provides a mop wringer, comprising:

[0005] The wringing frame is provided with a cleaning channel. On opposite sides of the cleaning channel are wringing components for squeezing and / or scraping the wiping material on the bottom surface of the mop board and abutting parts supported on the top surface of the mop board. A wringing port for inserting the mop board is formed between the wringing components and the abutting parts.

[0006] The driving unit is connected to the squeezing member. The driving unit is driven to expand or contract the squeezing member. When the squeezing member expands, the distance between any two opposite areas on the side wall gradually increases, which reduces the distance between the squeezing member and the abutting part. When the squeezing member contracts, the distance between any two opposite areas on the side wall gradually decreases, which increases the distance between the squeezing member and the abutting part.

[0007] Beneficial effects: This utility model provides a mop wringer frame. The drive unit drives the wringer component connected to it to move, so that the wringer component expands or contracts. This causes the distance between any two opposite areas on the side wall of the wringer component to gradually increase or decrease, thereby changing the distance between the wringer component and the contact part, and thus changing the size of the cleaning channel on the wringer frame. This allows the cleaning channel on the mop wringer frame to be adapted to different sizes of cotton wool, improving the user experience.

[0008] In one optional embodiment, the driving unit is rotatably disposed on the dewatering frame, and the driving unit is driven to rotate relative to the dewatering frame to cause the dewatering member to expand or contract.

[0009] Beneficial effects: The expansion or contraction of the squeezing component is achieved by the drive unit rotating relative to the squeezing frame, which is simple and efficient.

[0010] In one optional embodiment, the drive unit passes through the dewatering frame, and the dewatering member is arranged around the outer periphery of the drive unit and is throttle-connected to the outer peripheral wall of the drive unit.

[0011] The drive unit rotates under the drive, causing any two opposite areas on the side wall of the squeezing member to move away from or towards the drive unit, thus causing the squeezing member to expand or contract.

[0012] Beneficial effect: The water-squeezing component is arranged around the outer periphery of the drive unit to facilitate the installation of a transmission structure between the water-squeezing component and the drive unit, thereby enabling the drive unit to drive the water-squeezing component to expand or contract.

[0013] In one optional embodiment, a gear is arranged around the outer peripheral wall of the drive unit, and a rack is arranged on the side of the squeezing member near the drive unit. The drive unit is driven to rotate, which drives the gear to rotate. The gear drives the rack to move, and thus any two opposite areas on the side wall of the squeezing member move away from or towards the drive unit, causing the squeezing member to expand or contract.

[0014] Beneficial effects: By setting a meshing transmission assembly consisting of gears and racks between the drive unit and the squeezing component, any two opposite areas on the side wall of the squeezing component can move away from or towards the drive unit, thereby causing the squeezing component to expand or contract.

[0015] In one optional embodiment, the dewatering component includes at least a first side plate and a second side plate disposed opposite to each other. The first side plate and the second side plate are respectively disposed on both sides of the driving part, and a rack is provided on the side of the first side plate and the second side plate near the driving part. Two gears are respectively meshed with the two racks and driven around the outer peripheral wall of the driving part.

[0016] The drive unit rotates, causing the two gears to rotate. The rotation of the two gears causes the two racks to move. The movement of the two racks causes the first side plate and the second side plate to move closer to or further away from each other, causing the squeezing member to expand or contract.

[0017] Beneficial effects: The water-squeezing component is designed with a first side plate and a second side plate that are positioned opposite each other to form any two opposite areas on the side wall of the water-squeezing component. Through the rack and gear engagement between the first side plate and the second side plate and the drive unit, the first side plate and the second side plate can move in a direction away from or towards the drive unit, thus realizing the expansion or contraction of the water-squeezing component in a simple and efficient manner.

[0018] In one optional embodiment, the mop wringer further includes a locking structure. When the locking structure is locked, the drive unit is connected to the wringer, and the drive unit is driven to expand or contract the wringer. When the locking structure is unlocked, the drive unit is disengaged from the wringer, and the wringer rotates under the drive of the mop plate.

[0019] Beneficial effects: The locking structure with locked and unlocked states enables the water squeezing component to switch between driven volume change and normal water squeezing operation, ensuring that the water squeezing component can be adjusted and used normally.

[0020] In one optional embodiment, the drive unit includes an operating member and a drive shaft. The drive shaft passes through the dewatering frame and is rotatable relative to the dewatering frame. The end of the drive shaft extends out of the dewatering frame and is movably connected to the operating member. The dewatering member is arranged around the outer periphery of the drive shaft and is drively connected to the drive shaft.

[0021] The locking structure is disposed between the operating member and the drive shaft. When the locking structure is locked, the operating member and the drive shaft are circumferentially limited and connected. The operating member is driven to rotate, which drives the drive shaft to rotate. The rotation of the drive shaft drives the wringer to expand or contract. When the locking structure is unlocked, the operating member is disconnected from the drive shaft. The wringer rotates around the drive shaft as the rotation axis under the drive of the mop board.

[0022] Beneficial effects: The operating component of the drive unit is used to receive external force. The drive shaft of the drive unit transmits the rotation drive of the operating component to the squeezing component, thereby realizing the transmission of external force to the squeezing component through the operating component and the drive shaft. The structure is simple and the transmission is stable.

[0023] In one alternative embodiment, the locking structure includes a slot disposed on one of the operating member and the drive shaft, and a snap-fit ​​protrusion disposed on the other to engage with the slot.

[0024] When the operating member moves axially along the drive shaft until the snap-fit ​​protrusion inserts into the slot, thereby limiting the circumferential position of the operating member and the drive shaft, the locking structure locks; when the operating member moves axially along the drive shaft until the snap-fit ​​protrusion disengages from the slot, the locking structure unlocks.

[0025] Beneficial effects: The locking and unlocking of the locking structure between the operating component and the drive shaft is achieved through the engagement and disengagement of the slots and protrusions. The structure is simple and the engagement is stable.

[0026] In one optional embodiment, the dewatering frame is provided with a through hole, and the end of the drive shaft passes through the through hole and exits the dewatering frame; an extension plate is provided around the through hole on the dewatering frame, and the operating member is sleeved on the extension plate.

[0027] An anti-detachment part is provided between the extension plate and the operating member, and the anti-detachment part is adapted to prevent the operating member from disengaging from the extension plate when the operating member moves axially along the drive shaft.

[0028] Beneficial effects: The dewatering frame has an extension plate with perforations around it to provide an installation position for the operating component; an anti-detachment part is provided between the extension plate and the operating component to prevent the operating component from detaching from the extension plate when it moves axially along the drive shaft, thereby improving the stability of the operating component in use.

[0029] In one optional embodiment, the operating member is sleeved on the outer periphery of the extension plate, and the anti-detachment part includes an anti-detachment rib provided on the outer peripheral wall of the extension plate and an anti-detachment component provided on the inner wall of the operating member;

[0030] When the operating component moves to its maximum displacement along the axial direction of the drive shaft away from the dewatering frame, the anti-detachment component abuts against the anti-detachment rib.

[0031] Beneficial effects: Anti-detachment ribs and anti-detachment components are provided between the extension plate and the operating component. When the operating component moves to its maximum displacement along the axial direction of the drive shaft away from the squeezing frame, the anti-detachment component and the anti-detachment rib engage to prevent the operating component from detaching from the extension plate.

[0032] In an optional embodiment, when the dewatering member includes at least a first side plate and a second side plate disposed opposite to each other, the dewatering member further includes a mounting side plate disposed in cooperation with the ends of the first side plate and the second side plate respectively;

[0033] The mounting side plate is provided with two positioning guide structures corresponding to the first side plate and the second side plate respectively. When the driving part is driven to move the first side plate and the second side plate away from each other or move closer to each other, the ends of the first side plate and the second side plate slide along the corresponding positioning guide structures respectively.

[0034] Beneficial effects: The positioning and guiding structure of the mounting side plate guides the sliding of the first and second side plates, thereby improving the stability of the movement of the first and second side plates; at the same time, it limits the movement of the first and second side plates.

[0035] In one optional embodiment, the positioning guide structure is provided with multiple snap-fit ​​positions. When the driving part is driven to move the first side plate and the second side plate away from each other or close to each other, the first side plate and the second side plate respectively snap-fit ​​with different snap-fit ​​positions on the corresponding positioning guide structure in sequence. When snap-fitting with different snap-fit ​​positions, the distance between the squeezing member and the abutment part is different.

[0036] Beneficial effects: The snap-fit ​​position in the positioning guide structure limits the first and second side plates, ensuring that the water squeezing component can maintain its expanded or contracted volume when the first and second side plates are adjusted to different positions.

[0037] Secondly, this utility model also provides a mop, including the mop wringer described in any of the above embodiments.

[0038] Since mops include a wringer and have the same effect as a wringer, they will not be described in detail here. Attached Figure Description

[0056] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0057] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0058] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. 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.

[0059] 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.

[0060] The current wringer's cleaning channel opening size cannot be adjusted. If the cleaning channel opening is designed to accommodate new PVA sponges, then when the PVA sponges age and shrink, or when replacing them with smaller sponges, the sidewalls of the cleaning channel on the wringer cannot effectively squeeze or scrape the shrunken sponges, resulting in incomplete wringing out of the sponges. Conversely, if the cleaning channel opening is too small to allow for proper wringing out of aged PVA sponges, an excessively small opening makes it more difficult for users to wring out new or smaller PVA sponges, requiring more force from the wringer. Therefore, the current wringer design is unreasonable, making it unable to handle wringing out PVA sponges of different sizes, affecting the user experience. To address this, this embodiment provides a mop wringer and mop to solve the problem of the current wringer's cleaning channel opening size not being adjustable, thus preventing it from handling wringing out PVA sponges of different sizes.

[0061] The following is combined Figures 1-6 The following describes embodiments of the present invention.

[0062] According to an embodiment of the present invention, in one aspect, a mop wringer is provided, such as... Figure 1 , Figure 2 As shown, it includes: a squeezing frame 110, a squeezing member 120, an abutment part 130, a squeezing nozzle 140, and a drive part 150.

[0063] The wringing frame 110 has a cleaning channel 111. On opposite sides of the cleaning channel 111 are wringing elements 120 for squeezing and / or scraping the wiping material 210 on the bottom surface of the mop board 200 and abutment portions 130 supported on the top surface of the mop board 200. A wringing port 140 for inserting the mop board 200 is formed between the wringing elements 120 and the abutment portions 130. The driving unit 150 is connected to the wringing elements 120. The driving unit 150 drives the wringing elements 120 to expand or contract. When the wringing elements 120 expands, the distance between any two opposite areas on the side wall gradually increases, which reduces the distance between the wringing elements 120 and the abutment portions 130. When the wringing elements 120 contracts, the distance between any two opposite areas on the side wall gradually decreases, which increases the distance between the wringing elements 120 and the abutment portions 130.

[0064] In the above embodiment, the drive unit 150 drives the wringer 120 connected to it to move, so that the wringer 120 expands or contracts, so that the distance between any two opposite areas on the side wall of the wringer 120 gradually increases or decreases, thereby changing the distance between the wringer 120 and the contact part 130, and thus changing the size of the opening of the cleaning channel 111 on the wringer frame 110. This allows the cleaning channel 111 on the mop wringer frame 100 to be adapted to different sizes of cotton wool, improving the user experience.

[0065] Specifically, the wringer frame 110 has a sleeve rod on one side of the abutment portion 130 that is movably connected to the mop handle 300, and a wringer 120 on the side opposite to the abutment portion 130. The wringer 120 is fixed or rotatable, so that when the mop wringer frame 100 moves axially closer to the mop handle 300, the wringer plate 200 is inserted into the wringer opening 140 and enters between the wringer 120 and the abutment portion 130 on both sides of the cleaning channel 111. As the mop wringer frame 100 moves axially back and forth relative to the mop handle 300, the wringer 120 squeezes and scrapes the wiping material 210, i.e., the cotton, on the bottom surface of the mop plate 200, thereby squeezing out water from the wiping material 210.

[0066] Furthermore, when the drive unit 150 is driven to expand or contract the squeezing member 120, the distance between any two opposite areas on the side wall of the squeezing member 120 gradually increases or decreases during expansion. These two opposite areas can be between two sets of movable plates on the split squeezing member 120, driven by the drive unit 150 formed by gears, transmission plates, etc., or they can be two opposite parts on the integral and elastic squeezing member 120, whose volume is changed by the change in air pressure through the drive unit 150 formed by the cylinder. This causes the distance between the outer wall of the squeezing member 120 and the contact part 130 to decrease or increase, thereby causing the diameter of the cleaning channel 111 on the squeezing frame 110 to decrease or increase.

[0067] In some embodiments, such as Figure 2 As shown, the drive unit 150 is rotatably mounted on the squeezing frame 110. The drive unit 150 is driven to rotate relative to the squeezing frame 110, causing the squeezing member 120 to expand or contract.

[0068] In the above embodiments, the expansion or contraction of the squeezing member 120 is achieved by the drive unit 150 rotating relative to the squeezing frame 110, which is simple and efficient.

[0069] Specifically, when the drive unit 150 is rotatably disposed on the squeezing frame 110, it can be disposed on one side of the squeezing member 120 or disposed inside the squeezing member 120, thereby forming a transmission connection with the squeezing member 120 to drive the squeezing member 120 to expand or contract.

[0070] In some embodiments, such as Figure 3 , Figure 4 , Figure 5 As shown, the drive unit 150 passes through the squeezing frame 110, and the squeezing member 120 is arranged around the outer periphery of the drive unit 150 and is connected to the outer peripheral wall of the drive unit 150 in a transmission manner. When the drive unit 150 is driven to rotate, any two opposite areas on the side wall of the squeezing member 120 move away from or towards the drive unit 150, so that the squeezing member 120 expands or contracts.

[0071] In the above embodiment, the squeezing member 120 is arranged around the outer periphery of the driving part 150 so as to facilitate the provision of a transmission structure between the squeezing member 120 and the driving part 150, thereby enabling the driving part 150 to drive the squeezing member 120 to expand or contract.

[0072] Specifically, when the drive unit 150 is driven to rotate, causing any two opposite areas on the side wall of the squeezing member 120 to move away from the drive unit 150, the squeezing member 120 expands; when the drive unit 150 is driven to rotate, causing any two opposite areas on the side wall of the squeezing member 120 to move closer to the drive unit 150, the squeezing member 120 contracts.

[0073] Furthermore, this embodiment does not limit the specific structural form and engagement method of the transmission structure between the water-squeezing component 120 and the drive unit 150. Specifically, it includes, but is not limited to, the meshing engagement of gears and racks, and the sliding engagement of guide plates and guide grooves.

[0074] In some embodiments, such as Figure 4 , Figure 5 As shown, a gear 151 is arranged around the outer peripheral wall of the drive unit 150, and a rack 121 is arranged on the side of the squeezing member 120 near the drive unit 150. When the drive unit 150 is driven to rotate, the gear 151 rotates, and the gear 151 drives the rack 121 to move. As a result, any two opposite areas on the side wall of the squeezing member 120 move away from or towards the drive unit 150, causing the squeezing member 120 to expand or contract.

[0075] In the above embodiment, a meshing transmission assembly consisting of a gear 151 and a rack 121 is provided between the drive unit 150 and the squeezing member 120, so that any two opposite areas on the side wall of the squeezing member 120 can move away from or towards the drive unit 150, so that the squeezing member 120 can expand or contract.

[0076] Specifically, a gear 151 and a rack 121 are provided between the drive unit 150 and the squeezing member 120, so that the rotation of the gear 151 driven by the drive unit 150 is converted into parallel movement in opposite directions between any two opposite areas on the side wall of the squeezing member 120, thereby making any two opposite areas on the side wall of the squeezing member 120 move closer to each other or further away from each other.

[0077] In some embodiments, such as Figure 4 , Figure 5 As shown, the squeezing member 120 includes at least a first side plate 122 and a second side plate 123 arranged opposite to each other. The first side plate 122 and the second side plate 123 are respectively arranged on both sides of the driving part 150, and a rack 121 is provided on the side of the first side plate 122 and the second side plate 123 near the driving part 150. Two gears 151 are arranged around the outer peripheral wall of the driving part 150, which mesh with the two racks 121 respectively. When the driving part 150 is driven to rotate, it drives the two gears 151 to rotate. The rotation of the two gears 151 drives the two racks 121 to move. The movement of the two racks 121 causes the first side plate 122 and the second side plate 123 to move closer or further away from each other, so that the squeezing member 120 expands or contracts.

[0078] In the above embodiment, the water-squeezing member 120 is designed with a first side plate 122 and a second side plate 123 arranged opposite to each other to form any two opposite areas on the side wall of the water-squeezing member 120. Through the cooperation of the rack 121 and gear 151 between the first side plate 122 and the second side plate 123 and the drive part 150, the first side plate 122 and the second side plate 123 can both move away from or towards the drive part 150, so as to realize the expansion or contraction of the water-squeezing member 120 in a simple and efficient manner.

[0079] Specifically, the first side plate 122 and the second side plate 123, which are arranged opposite to each other, can be arranged in one or more sets on the outer periphery of the drive part 150. That is, the outer wall of the water squeezing member 120 can be composed of two, four, six or more symmetrically arranged side plates. In addition, the meshing transmission assembly of the gear 151 and the rack 121 can also be arranged in two, four, six or more sets to ensure that each side plate and the drive part 150 are provided with at least one set of meshing transmission assembly of the gear 151 and the rack 121. In this embodiment, the first side plate 122 and the second side plate 123 are arranged in two sets on the outer periphery of the drive part 150, for a total of four side plates; each side plate is provided with two racks 121, and the drive part 150 is also provided with two corresponding gears 151.

[0080] Furthermore, in this embodiment, Figure 5 From the perspective of the drive unit 150 driving the gear 151 to rotate clockwise, each rack 121 moves outward, causing the first side plate 122 and the second side plate 123 to move away from each other, thereby causing the squeezing member 120 to expand; when the drive unit 150 drives the gear 151 to rotate counterclockwise, each rack 121 moves inward, causing the first side plate 122 and the second side plate 123 to move closer to each other, thereby causing the squeezing member 120 to contract.

[0081] Furthermore, in this embodiment, adjacent side plates are perpendicular to each other, and the racks 121 corresponding to the two side plates are also perpendicular to each other. Therefore, four racks 121 mesh with one gear 151. In this embodiment, the width of the gear 151 is designed to be greater than the width of two racks 121. One gear 151 has two meshing areas with a width equivalent to the width of the racks 121. Two parallel racks 121 mesh with the gear 151 in one meshing area, thereby avoiding motion interference between two perpendicular racks 121.

[0082] In some embodiments, the mop wringer also includes a locking structure. When the locking structure is locked, the drive unit 150 is connected to the wringer 120, and the drive unit 150 is driven to move and cause the wringer 120 to expand or contract. When the locking structure is unlocked, the drive unit 150 is disengaged from the wringer 120, and the wringer 120 rotates under the drive of the mop plate 200.

[0083] In the above embodiments, a locking structure with locked and unlocked states is provided to enable the dewatering component 120 to switch between driven volume change and normal dewatering operation, ensuring that the dewatering component 120 can be adjusted and used normally.

[0084] Specifically, the locking structure is used to adjust the driven state of the transmission component in the drive unit 150. When the locking structure is locked, the transmission component in the drive unit 150 can be driven by external force and drive the squeezing member 120 to expand or contract, thereby changing the volume of the squeezing member 120; when the locking structure is unlocked, the transmission component in the drive unit 150 cannot be driven by external force, and the squeezing member 120 can only rotate under the drive of the mop board 200, thereby realizing the normal squeezing operation of the squeezing member 120.

[0085] In some embodiments, such as Figure 4 , Figure 5 As shown, the drive unit 150 includes an operating member 152 and a drive shaft 153. The drive shaft 153 passes through the wringer frame 110 and can rotate relative to the wringer frame 110. The end of the drive shaft 153 extends out of the wringer frame 110 and is movably connected to the operating member 152. The wringer 120 is arranged around the outer periphery of the drive shaft 153 and is connected to the drive shaft 153 in a transmission manner. A locking structure is provided between the operating member 152 and the drive shaft 153. When the locking structure is locked, the operating member 152 is circumferentially limited to the drive shaft 153. The operating member 152 is driven to rotate, which drives the drive shaft 153 to rotate. The rotation of the drive shaft 153 drives the wringer 120 to expand or contract. When the locking structure is unlocked, the operating member 152 is disconnected from the drive shaft 153. The wringer 120 rotates around the drive shaft 153 as the rotation axis under the drive of the mop plate 200.

[0086] In the above embodiment, the operating member 152 of the drive unit 150 is used to receive the drive of external force, and the drive shaft 153 of the drive unit 150 transmits the rotation drive of the operating member 152 to the dewatering member 120, thereby realizing the transmission of external force to the dewatering member 120 through the operating member 152 and the drive shaft 153. The structure is simple and the transmission is stable.

[0087] Specifically, when the locking structure is locked, the operating member 152 is circumferentially limited to the drive shaft 153. The operating member 152 can transmit rotational power to the squeezing member 120 through the drive shaft 153, and drive the squeezing member 120 to expand or contract, that is, change the volume of the squeezing member 120. When the locking structure is unlocked, the operating member 152 is disconnected from the drive shaft 153. The operating member 152 cannot transmit rotational power to the squeezing member 120 through the drive shaft 153. The squeezing member 120 rotates around the drive shaft 153 under the drive of the mop board 200, that is, it can be driven to rotate freely on the squeezing frame 110 to squeeze water.

[0088] In some embodiments, such as Figure 5, Figure 6 As shown, the locking structure includes a slot 1521 disposed on one of the operating member 152 and the drive shaft 153, and a snap-fit ​​protrusion 1531 disposed on the other and engaging with the slot 1521; when the operating member 152 moves axially along the drive shaft 153 until the snap-fit ​​protrusion 1531 is inserted into the slot 1521, thereby limiting the circumferential movement of the operating member 152 and the drive shaft 153, the locking structure locks; when the operating member 152 moves axially along the drive shaft 153 until the snap-fit ​​protrusion 1531 disengages from the slot 1521, the locking structure unlocks.

[0089] In the above embodiments, the locking and unlocking of the locking structure between the operating member 152 and the drive shaft 153 is achieved through the engagement and disengagement of the slot 1521 and the engagement protrusion 1531. The structure is simple and the engagement is stable.

[0090] Specifically, the groove of the slot 1521 and the protrusion of the engaging protrusion 1531 are designed to form a stable engaging relationship between the slot 1521 and the engaging protrusion 1531, thereby facilitating the rotation of the drive shaft 153 by the operating member 152. In this embodiment, the operating member 152 is provided with a slot 1521, and the end of the drive shaft 153 is provided with an engaging protrusion 1531. When the operating member 152 moves along the axial direction of the drive shaft 153 toward the dewatering frame 110, the engaging protrusion 1531 can be inserted into the slot 1521; when the operating member 152 moves along the axial direction of the drive shaft 153 away from the dewatering frame 110, the engaging protrusion 1531 can be disengaged from the slot 1521.

[0091] In some embodiments, such as Figure 2 , Figure 3 , Figure 4 As shown, the squeezing frame 110 is provided with a through hole 112, and the end of the drive shaft 153 passes through the through hole 112 and exits the squeezing frame 110; an extension plate 113 is provided around the through hole 112 on the squeezing frame 110, and the operating member 152 is sleeved on the extension plate 113; an anti-detachment part is provided between the extension plate 113 and the operating member 152, and the anti-detachment part is adapted to restrict the operating member 152 from disengaging from the extension plate 113 when the operating member 152 moves axially along the drive shaft 153.

[0092] In the above embodiment, an extension plate 113 is provided around the perforation 112 on the dewatering frame 110 to provide an installation position for the operating member 152; an anti-detachment part is provided between the extension plate 113 and the operating member 152 to prevent the operating member 152 from detaching from the extension plate 113 when it moves axially along the drive shaft 153, thereby improving the stability of the operating member 152 in use.

[0093] Specifically, the anti-detachment part can be a combination structure of a buckle and a limiting protrusion, or two sets of limiting ribs that cooperate with each other.

[0094] In some embodiments, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the operating member 152 is sleeved on the outer periphery of the extension plate 113. The anti-detachment part includes an anti-detachment rib 1131 provided on the outer periphery wall of the extension plate 113 and an anti-detachment member 1522 provided on the inner wall of the operating member 152. When the operating member 152 moves to its maximum displacement along the axial direction of the drive shaft 153 away from the squeezing frame 110, the anti-detachment member 1522 abuts against the anti-detachment rib 1131.

[0095] In the above embodiment, an anti-detachment rib 1131 and an anti-detachment component 1522 are provided between the extension plate 113 and the operating component 152. When the operating component 152 moves to its maximum displacement along the axial direction of the drive shaft 153 away from the dewatering frame 110, the anti-detachment component 1522 abuts against the anti-detachment rib 1131 to prevent the operating component 152 from detaching from the extension plate 113.

[0096] Specifically, the outer contour of the extension plate 113 on the dewatering frame 110 is contoured to the internal cavity of the operating member 152 to improve the tightness of the assembly between the extension plate 113 and the operating member 152. The anti-detachment rib 1131 is set as an annular limiting rib on the outer peripheral wall of the extension plate 113, and the anti-detachment member 1522 is set as an annular limiting rib at the cavity opening of the operating member 152.

[0097] Furthermore, the outer peripheral wall of the extension plate 113 is provided with a guide groove 1132 arranged parallel to its axial direction, and the inner wall of the operating member 152 is provided with a guide rib 1523 arranged parallel to its axial direction. The guide rib 1523 is slidably fitted in the guide groove 1132 to ensure the stability of the operating member 152 when it moves along the axial direction of the drive shaft 153, and to improve the success rate of the engagement between the slot 1521 and the engagement protrusion 1531.

[0098] Furthermore, a spring 154 is provided between the outer periphery of the extension plate 113 and the bottom wall of the operating member 152. When the operating member 152 is manually driven to move closer to the squeezing frame 110 along the axial direction of the drive shaft 153, the spring 154 is compressed. At this time, the expansion or contraction of the squeezing member 120 is adjusted by the operating member 152 and the drive shaft 153. After the adjustment is completed, the manual force disappears, the spring 154 resets and automatically drives the operating member 152 to move away from the squeezing frame 110 along the axial direction of the drive shaft 153. There is no need to manually apply force to the operating member 152 to disengage the slot 1521 and the snap-fit ​​protrusion 1531, thus avoiding the user forgetting to reset the operating member 152, which would cause the squeezing member 120 to rotate poorly when squeezing water.

[0099] In some embodiments, such as Figure 5As shown, when the dewatering component 120 includes at least a first side plate 122 and a second side plate 123 disposed opposite to each other, the dewatering component 120 also includes a mounting side plate 124 that is respectively configured to cooperate with the ends of the first side plate 122 and the second side plate 123; the mounting side plate 124 is provided with two positioning guide structures 125 that are respectively corresponding to the first side plate 122 and the second side plate 123; when the driving part 150 is driven to move the first side plate 122 and the second side plate 123 away from each other or close to each other, the ends of the first side plate 122 and the second side plate 123 slide along the corresponding positioning guide structures 125 respectively.

[0100] In the above embodiment, the positioning guide structure 125 of the mounting side plate 124 guides the sliding of the first side plate 122 and the second side plate 123 to improve the stability of the movement of the first side plate 122 and the second side plate 123; at the same time, it limits the movement of the first side plate 122 and the second side plate 123.

[0101] Specifically, the ends of the first side plate 122 and the second side plate 123 are both formed with plate bodies, and the plate bodies are provided with bosses. The bosses are used to slide and limit the positioning guide structure 125 which is constructed as a groove.

[0102] Furthermore, in this embodiment, each side of the first side plate 122 and the second side plate 123 is provided with a plate body, and each plate body is provided with a boss. The mounting side plate 124 is provided with four sets of positioning guide structures 125.

[0103] In some embodiments, as shown in Figure 5, the positioning guide structure 125 is provided with a plurality of snap-fit ​​positions 1251. When the driving part 150 is driven to move the first side plate 122 and the second side plate 123 away from each other or close to each other, the first side plate 122 and the second side plate 123 respectively snap-fit ​​with different snap-fit ​​positions 1251 on the corresponding positioning guide structure 125 in sequence. When snap-fitting with different snap-fit ​​positions 1251, the distance between the squeezing member 120 and the abutment part 130 is different.

[0104] In the above embodiment, the snap-fit ​​position 1251 in the positioning guide structure 125 is used to limit the first side plate 122 and the second side plate 123, so as to ensure that when the first side plate 122 and the second side plate 123 are adjusted to different positions, the water squeezing member 120 can maintain its own expanded or contracted volume.

[0105] Specifically, the snap-fit ​​position 1251 is provided in the positioning guide structure 125 in a through groove that is shaped to the end bosses of the first side plate 122 and the second side plate 123. Multiple through grooves corresponding to one of the first side plate 122 and the second side plate 123 are connected to each other so that the first side plate 122 and the second side plate 123 can be fixed in multiple positions to realize the volume adjustment of the dewatering component 120 in multiple sizes.

[0106] Furthermore, as an alternative implementation, the plates at the ends of the first side plate 122 and the second side plate 123 directly abut against the mounting side plate 124, using the friction between them to limit the first side plate 122 and the second side plate 123.

[0107] According to an embodiment of the present invention, another aspect also provides a mop, such as... Figure 1 As shown, a mop wringer 100 including any of the above embodiments is included.

[0108] 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.
