[0002] Currently, mop buckets typically feature two separate chambers: a cleaning chamber and a dehydration chamber. A rubbing and squeezing mechanism is installed at the openings of the bucket, corresponding to the cleaning and dehydration chambers. After inserting the mop blade into the cleaning chamber to wet it, the user pumps the mop handle up and down, using the rubbing and squeezing mechanism to clean the mop head. The mop blade is then inserted into the dehydration chamber, where the user pumps the handle up and down, using the rubbing and squeezing mechanism to dehydrate the mop blade, completing both the cleaning and dehydration operations.

[0003] As the mop undergoes multiple dehydration operations in the dehydration chamber, a large amount of sewage squeezed out from the wipes on the mop plate will accumulate at the bottom of the dehydration chamber.

[0195] In the above embodiment, a pumping device and a linkage device connected to the pumping device are provided, so that when the mop board moves up and down along the stroking mouth squeezing mechanism 901 to stroke water, the sewage in the dehydration chamber 102 is discharged into the cleaning chamber 101, thereby avoiding contact between the mop board and the accumulated sewage in the dehydration chamber 102, and further avoiding secondary contamination of the wipes of the mop board that have been cleaned in the cleaning chamber 101.

[0196] Specifically, the pumping device can be configured as a water pump, a negative pressure pumping mechanism, etc.

[0197] Furthermore, the water inlet 201 is extended toward the bottom of the dehydration chamber 102 to facilitate the pumping operation. In this embodiment, the water inlet 201 can be connected to a pipeline so that the water inlet 201 is extended to the bottom of the dehydration chamber 102.

[0198] In some embodiments, as Figures 1-4 As shown, the linkage device includes a rotatable driving member 3 and a transmission structure, which are respectively connected to the driving member 3 and the pumping device; when the mop plate moves downward along the stroking and squeezing mechanism 901, the driving member 3 is driven to rotate in the forward direction, and when the mop plate moves upward along the stroking and squeezing mechanism 901, the driving member 3 is driven to rotate in the reverse direction. The forward and reverse rotations of the driving member 3 both drive the transmission structure to drive the pumping device to discharge the sewage in the dehydration chamber 102 into the cleaning chamber 101.

[0199] Specifically, the driving member 3 can be configured as a rotation driving structure such as a gear or a wheel, and the specific connection form of the corresponding transmission connection can be a gear transmission connection, a force transmission connecting rod transmission connection, etc.

[0200] In some embodiments, as Figures 1-4 As shown, the transmission structure includes a gear module. The forward and reverse rotations of the driving member 3 drive the gear module to operate. The operation of the gear module drives the pumping device to discharge the sewage in the dehydration chamber 102 into the cleaning chamber 101.

[0201] In the above embodiment, a gear module is provided between the driving member 3 and the pumping device, and the labor-saving characteristics of the gear module transmission connection are utilized to help the mop plate move up and down along the stroking extrusion mechanism 901 to drive the driving member 3, thereby improving the pumping efficiency of the pumping device, and further improving the drainage efficiency of discharging the sewage in the dehydration chamber 102 into the cleaning chamber 101.

[0202] In some embodiments, as Figures 1-4 As shown, the gear module includes a first gear 4 that is transmission-connected to the driving member 3, and the first gear 4 is transmission-connected to the pumping device; the driving member 3 rotates forward or reversely to drive the first gear 4 to rotate forward or reversely, and the first gear 4 rotates forward or reversely to drive the pumping device to discharge the sewage in the dehydration chamber 102 into the cleaning chamber 101.

[0203] Specifically, since the first gear 4 is transmission-connected to the water pumping device, in the intermediate structural member of the transmission connection, the part transmission-connected to the first gear 4 can be set as a gear, and the part transmission-connected to the water pumping device can be set as a force transmission connecting rod.

[0204] In some embodiments, as Figures 1-4As shown, the gear module also includes a second gear 5 meshing with the first gear 4, and the second gear 5 is connected to the pumping device; the forward or reverse rotation of the first gear 4 drives the second gear 5 to rotate reversely or forwardly; the reverse rotation and forward rotation of the second gear 5 both drive the pumping device to discharge the sewage in the dehydration chamber 102 into the cleaning chamber 101.

[0205] Specifically, the diameter of the first gear 4 is smaller than that of the second gear 5, so that the first gear 4 and the second gear 5 have a smaller transmission ratio when they are engaged and transmitted, but the labor-saving efficiency is better, so as to help the mop plate move up and down along the stroking extrusion mechanism 901 to drive the driving member 3, thereby improving the pumping efficiency of the pumping device.

[0206] In some embodiments, as Figures 1-4 As shown, the first gear 4 is coaxially arranged with the driving member 3 .

[0207] Specifically, the first gear 4 is coaxially arranged with the driving member 3. When the mop plate moves up and down along the stroking and squeezing mechanism 901, the driving member 3 rotates synchronously with the first gear 4, so that the first gear 4 drives the second gear 5 meshing with it to rotate, thereby driving the water pumping device to work.

[0213] In the above embodiment, the driving member 3 and the first gear 4 are fixedly mounted on the first end and the second end of the rotating roller 7, respectively, so as to ensure that the rotating roller 7 does not protrude from the driving member 3 or the first gear 4, thereby avoiding interference between the rotating roller 7 and the mop plate moving up and down.

[0216] In some embodiments, as Figures 1-4 As shown, a fixing groove is formed on one side of the driving member 3 close to the first mounting plate 6, and a plurality of mounting holes are provided on the bottom wall of the fixing groove; when the driving member 3 is sleeved and fixed on the outer periphery of the second end of the rotating roller 7, the plurality of elastic arms at the second end of the rotating roller 7 respectively penetrate into the plurality of mounting holes and engage with the plurality of mounting holes.

[0217] In the above embodiment, the multiple mounting holes in the fixing groove provide accommodation positions for the elastic arms, so that the multiple elastic arms are stably engaged with the multiple mounting holes, thereby enabling the driving member 3 to be stably fixedly connected to the rotating roller 7.

[0218] In some embodiments, as Figures 1-4 As shown, the rotating roller 7 is a hollow structure, and a cylindrical protrusion is provided at the center of the fixing groove.

[0226] In the above embodiment, an installation area is formed between the second installation plate 8 and the first installation plate 6, and the transmission structure is arranged in the installation area to prevent water in the cleaning chamber 101 from soaking the transmission structure, thereby ensuring that the transmission structure can operate stably.

[0227] In some embodiments, as Figures 1-4 As shown, the transmission structure includes a first gear 4 coaxially arranged with the driving member 3 and a second gear 5 meshing with the first gear 4 ; the second gear 5 is rotatably connected to the second mounting plate 8 .

[0229] In some embodiments, as Figures 1-4 As shown, the driving member 3 and the first gear 4 are rotatably connected to the first mounting plate 6 through the rotating roller 7, and the rotating roller 7 is a hollow structure; the second mounting plate 8 is provided with a plug-in column, and the top of the plug-in column has multiple spring buckles. The plug-in column is inserted into the hollow area of ​​the rotating roller 7 and is clamped with the side wall of the hollow area.

[0230] In the above embodiment, the hollow structure of the rotating roller 7 is nested and connected with the plug-in column on the second mounting plate 8, and the multiple spring clips at the top of the plug-in column are clamped with the hollow area of ​​the rotating roller 7 to achieve a stable connection of the rotating roller 7 on the second mounting plate 8, so that the rotating roller 7 is stably fixedly installed on the first mounting plate 6 and the second mounting plate 8 at the same time.

[0231] In some embodiments, as Figures 1-4 As shown, one of the first mounting plate 6 and the second mounting plate 8 is provided with a buckle, and the other of the first mounting plate 6 and the second mounting plate 8 is provided with a slot; the buckle and the slot are connected so that the first mounting plate 6 is fixed to the second mounting plate 8.

[0236] Furthermore, a mounting groove is provided at one end of the connecting plate facing the second mounting plate 8, and a support platform is provided on the side wall of the mop bucket. A support block that cooperates with the mounting groove is provided on the support platform facing the stroking extrusion mechanism 901; the connecting plate is fixed on the support platform through the interference fit between the mounting groove and the support block.

[0237] In some embodiments, as Figures 1-4 As shown, the pumping device is fixedly mounted on the second mounting plate 8 and is in transmission connection with the second gear 5 .

[0238] In the above embodiment, the second mounting plate 8 provides an installation location for the water pumping device, ensuring that the water pumping device can operate stably.

[0239] In some embodiments, as Figures 1-4As shown, the driving member 3 is a guide wheel or a gear. When the mop plate moves up and down along the stroking mouth squeezing mechanism 901 to swipe water, it abuts against the guide wheel or gear and drives the guide wheel or gear to rotate.

[0240] Specifically, when the driving member 3 is set as a guide wheel, the mop plate abuts against the guide wheel when it moves up and down along the stroking mouth squeezing mechanism 901 to stroke water, thereby relying on friction to drive the driving member 3 to rotate; when the driving member 3 is set as a gear, a rack meshing with the gear is correspondingly provided on the mop plate, and the gear and rack are meshed when the mop plate moves up and down along the stroking mouth squeezing mechanism 901 to stroke water, thereby the gear and rack meshing transmission drives the driving member 3 to rotate.

[0241] In some embodiments, as Figures 1-4 As shown, the mop plate abuts against the guide wheel when it moves up and down along the mop mouth squeezing mechanism 901 to pry water, and drives the guide wheel to rotate through the friction between the mop plate and the outer peripheral surface of the guide wheel. The outer peripheral surface of the guide wheel has a pattern that increases the friction; and / or, the outer periphery of the gear is provided with teeth with a triangular or trapezoidal cross-section.

[0243] In some embodiments, as Figures 1-4 As shown, the pumping device includes a negative pressure mechanism 10, and the linkage device is transmission-connected to the negative pressure mechanism 10. When the mop plate moves up and down along the stroking mouth squeezing mechanism 901 to swipe water, the linkage device is driven to drive the negative pressure mechanism 10 to discharge the sewage in the dehydration chamber 102 into the cleaning chamber 101.

[0244] In the above embodiment, the negative pressure mechanism 10 in the pumping device utilizes the negative pressure principle to pump water, thereby discharging the sewage in the dehydration chamber 102 into the cleaning chamber 101 .

[0245] In some embodiments, as Figures 1-4 As shown, the negative pressure mechanism 10 includes a rod body 1001, a piston 1002 and a piston tube 1003. One end of the rod body 1001 is connected to the piston 1002, and the other end is connected to the linkage device. When the mop plate moves up and down along the stroking mouth squeezing mechanism 901 to swipe water, the linkage device is driven to operate, and the operation of the linkage device drives the piston 1002 connected to the rod body 1001 to reciprocate in the piston tube 1003 to discharge the sewage in the dehydration chamber 102 into the cleaning chamber 101.

[0246] Specifically, the piston 1002 is interference fit with the inner wall of the piston tube 1003 and can move relative to the inside of the piston tube 1003. One end of the rod body 1001 is rotatably connected to the piston 1002, and the other end is rotatably connected to the linkage device.

[0247] In some embodiments, as Figures 1-4 As shown, the linkage device includes a driving member 3 and an output gear connected to the driving member 3. When the mop plate moves up and down along the stroking mouth squeezing mechanism 901 to swipe water, it drives the driving member 3 to rotate forward or reversely. The forward or reverse rotation of the driving member 3 drives the output gear to rotate forward or reversely. The output gear is the gear that outputs power of the linkage device. One end of the rod body 1001 is connected to the piston 1002, and the other end is connected to the non-center position of the output gear. The forward or reverse rotation of the output gear drives the piston 1002 connected to the rod body 1001 to reciprocate in the piston tube 1003.

[0248] Specifically, the output gear is the second gear 5; the connection position between the rod body 1001 and the output gear is located on the non-center end face of the output gear, that is, an eccentric connection is performed, so that the rotation of the output gear can drive the rod body 1001 to reciprocate, so that the negative pressure mechanism 10 can pump water.

[0249] Furthermore, the linkage device includes a driving member 3 and an output gear connected to the driving member 3. When the mop plate moves along the stroking mouth squeezing mechanism 901 to swipe water, the driving member 3 is driven to rotate, and the driving member 3 rotates to drive the output gear to rotate; the output gear is the gear that outputs power of the linkage device; one end of the rod body 1001 is connected to the piston 1002, and the other end is provided with a rack and meshes with the output gear. The rotation of the output gear drives the piston 1002 connected to the rod body 1001 to move in the piston tube 1003.

[0250] Furthermore, the water outlet 202 is arranged toward the stroking and squeezing mechanism 901 .

[0251] Furthermore, a detachable grille cover is provided at the end of the water outlet 202 .

[0252] Furthermore, the pumping device includes a tee 11, which is connected to the water outlet 202, the water inlet 201 and the negative pressure mechanism 10 respectively; the tee 11 is extended along the direction in which the mop plate is inserted into the stroking and squeezing mechanism 901, and the water outlet 202 is formed at one end of the tee 11 close to the stroking and squeezing mechanism 901, and the end of the tee 11 away from the stroking and squeezing mechanism 901 is connected to the pipe 2, and the end of the pipe 2 away from the tee 11 forms the water inlet 201, and the middle part of the tee 11 is connected to the negative pressure mechanism 10.

[0253] Furthermore, the end of the pipe 2 forming the water inlet 201 is extended toward the bottom of the dehydration chamber 102 to facilitate the discharge of sewage at the bottom of the dehydration chamber 102 .

[0254] Furthermore, if Figure 5 As shown, the three-way member 11 is also provided with an inlet check valve 12 corresponding to the water inlet 201 and a water outlet check valve 13 corresponding to the water outlet 202. When the negative pressure mechanism 10 is pumping water, the inlet check valve 12 opens and the water outlet check valve 13 closes. When the negative pressure mechanism 10 is draining water, the inlet check valve 12 closes and the water outlet check valve 13 opens, thereby draining the sewage in the dehydration chamber 102 into the cleaning chamber 101. The inlet check valve 12 and the water outlet check valve 13 include an aperture and a valve ball. The diameter of the valve ball is larger than the diameter of the aperture. When sewage flows through the aperture, it can drive the valve ball to close or open the aperture.

[0255] In some embodiments, as Figures 1-4 As shown, the mop bucket is also provided with a driven part 14 corresponding to the linkage device; when the mop board moves up and down along the stroking mouth squeezing mechanism 901 to stroke water, one side of the mop board drives the linkage device to operate, and the driven part 14 abuts against the other side of the mop board to provide support force to the mop board.

[0256] In the above embodiment, the driven member 14 abuts against the other side of the mop board to provide support force to the mop board, so that the driven member 14 and the driving member 3 cooperate with each other to limit the mop board, thereby improving the stability of the mop board in moving up and down.

[0257] Specifically, when the mop plate moves up and down along the stroking mouth squeezing mechanism 901 to swipe water, the mop plate is located between the driven member 14 and the driving member 3 to operate.

[0258] Furthermore, the driven component 14 can be configured as a fixed protruding structure or a rotating structure.

[0259] In some embodiments, as Figures 1-4 As shown, the driven member 14 is a rotating wheel arranged opposite to the linkage device; when the mop plate moves up and down along the stroking mouth squeezing mechanism 901 to swipe water, the other side of the mop plate drives the rotating wheel to rotate.

[0260] In the above embodiment, the rotating wheel can rotate when the mop plate moves up and down along the stroking mouth squeezing mechanism 901 to swipe water, thereby further improving the stability of the mop plate moving up and down.

[0261] In some embodiments, as Figures 1-4 As shown, the mop bucket also includes a first mounting plate 6, which extends along the direction in which the mop plate is inserted into the stroking and squeezing mechanism 901 and is arranged below the restraining side of the stroking and squeezing mechanism 901; the rotating wheel is rotatably arranged on the first mounting plate 6.

[0262] In the above embodiment, the first mounting plate 6 provides a mounting position for the rotating wheel.

[0263] In some embodiments, as Figures 1-4 As shown, the first mounting plate 6 is provided with a connecting roller 15 , and a through hole is provided at the center of the rotating wheel. The connecting roller 15 is inserted into the through hole so that the rotating wheel rotates relative to the connecting roller 15 .

[0264] In the above embodiment, the rotating wheel is installed by means of the connecting roller 15 rotatably engaged with the through hole, so that the rotating wheel is rotatably installed on the first mounting plate 6 .

[0265] In some embodiments, as Figures 1-4 As shown, a snap-fit ​​buckle is provided at the top end of the connecting roller 15 , and the connecting roller 15 is inserted into the through hole of the rotating wheel, and the snap-fit ​​buckle is snap-fitted with the side wall of the through hole.

[0266] In the above embodiment, the snap buckle is snapped into engagement with the side wall of the through hole, so that the driven component 14 , ie, the rotating wheel, and the connecting roller 15 are stably and fixedly connected.

[0267] Specifically, the rotating wheel is a gear. When the mop plate moves up and down along the mop mouth squeezing mechanism 901 to pry water, the rotating wheel set as a gear is engaged with another rack provided on the mop plate.

[0268] In some embodiments, as Figures 1-4 As shown, the side wall of the through hole is provided with an annular boss, and the snap buckle is snapped into engagement with the annular boss.

[0269] In the above embodiment, the snap-fit ​​buckle is snap-fitted to the annular boss, thereby achieving a stable fixed connection between the driven component, ie, the rotating wheel, and the connecting roller.

[0270] The working process is as follows:

[0271] When the mop plate moves up and down along the stroking mouth squeezing mechanism 901 to stroke water, the two sets of racks of the mop plate form a gear meshing transmission with the driving member 3 and the driven member 14 respectively. At this time, the driving member 3 rotates and drives the coaxially arranged first gear 4 to rotate. The first gear 4 drives the second gear 5 meshing with it to rotate, and the second gear 5 drives the rod body 1001 of the negative pressure mechanism 10 to move, so that the rod body 1001 drives the piston 1002 of the negative pressure mechanism 10 to reciprocate in the piston tube 1003 of the negative pressure mechanism 10, thereby discharging the sewage in the dehydration chamber 102 into the cleaning chamber 101.

[0272] According to an embodiment of the present invention, on the other hand, another mop bucket is provided, comprising: a bucket body 1 and a pumping device.

[0273] The barrel body 1 is provided with a cleaning chamber 101 and a dehydration chamber 102, and the opening of the cleaning chamber 101 is provided with a stroking and squeezing mechanism 901; the pumping device includes a water inlet 201 and a water outlet 202, the water inlet 201 is connected to the dehydration chamber 102, and the water outlet 202 is connected to the cleaning chamber 101, and the pumping device is arranged in the cleaning chamber 101; when the mop board moves in the cleaning chamber 101 and is cleaned by the stroking and squeezing mechanism 901, the pumping device is driven to operate, and the operation of the pumping device discharges the sewage stored in the dehydration chamber 102 retained when the mop board is dehydrated before cleaning the mop board into the cleaning chamber 101.

[0274] In the above embodiment, a pumping device is provided, and when the mop board moves along the cleaning chamber 101 and is cleaned by the stroking and squeezing mechanism 901, the pumping device is driven to operate, so that the pumping device operates to discharge the sewage stored in the dehydration chamber 102, which is retained when the mop board is dehydrated before cleaning, into the cleaning chamber 101, thereby avoiding contact between the mop board and the accumulated sewage in the dehydration chamber 102, and further avoiding secondary contamination of the wipes of the mop board that have been cleaned in the cleaning chamber 101.

[0275] Specifically, the pumping device can be configured as a water pump, a negative pressure pumping mechanism, etc.

[0276] Furthermore, the water inlet 201 is extended toward the bottom of the dehydration chamber 102 to facilitate the pumping operation. In this embodiment, the water inlet 201 can be connected to a pipeline so that the water inlet 201 is extended to the bottom of the dehydration chamber 102.

[0277] In some embodiments, as Figures 1-4 As shown, the dehydration chamber 102 is provided with a dehydration area and a temporary storage area connected to the dehydration area. The sewage generated by the mop board during dehydration flows into the temporary storage area. The water inlet 201 is connected to the temporary storage area. When the mop board moves along the stroking mouth squeezing mechanism 901 to swipe water, it is suitable to start the pumping device to discharge the sewage in the temporary storage area into the cleaning chamber 101.

[0278] In the above embodiment, the dehydration chamber 102 is divided into a dehydration area and a temporary storage area. The mop board moves in the cleaning chamber 101 and the mop board is cleaned by the stroking and squeezing mechanism 901 in the dehydration area. The sewage removed from the mop board flows from the dehydration area to the temporary storage area, so that the pumping device can discharge the sewage from the temporary storage area into the cleaning chamber 101.

[0279] Specifically, the dehydration area is located below the temporary storage area. The sewage removed from the mop board naturally flows from the dehydration area to the temporary storage area due to gravity. The water inlet 201 extends toward the temporary storage area at the bottom of the dehydration chamber 102 to facilitate pumping operations.

[0280] In some embodiments, as Figures 1-4As shown, the dehydration chamber 102 is provided with a blocking structure for limiting the mop plate from entering the temporary storage area.

[0281] In the above embodiment, the resisting structure is provided to prevent the mop plate from entering the temporary storage area with sewage and being contaminated.

[0282] In some embodiments, as Figures 1-4 As shown, the blocking structure is a boss, which is provided on the bottom surface of the dehydration chamber 102 ; a gap exists between the side wall of the boss and the inner wall of the dehydration chamber 102 to form a temporary storage area.

[0283] In some embodiments, as Figures 1-4 As shown, the retaining structure is a retaining plate with meshes, the edge of the retaining plate is fixed to the side wall of the dehydration chamber 102 , and a temporary storage area is formed between the retaining plate and the bottom wall of the dehydration chamber 102 .

[0284] In the above embodiment, the retaining structure is provided as a retaining plate with meshes, so that the wastewater removed from the mop board in the dehydration area can flow from the retaining plate to the temporary storage area.

[0285] In some embodiments, as Figures 1-4 As shown, the mop bucket also includes a linkage device, which is transmission-connected to the pumping device. When the mop plate moves along the stroking mouth squeezing mechanism 901 to swipe water, it is suitable for starting the pumping device to discharge the sewage in the temporary storage area into the cleaning chamber 101.

[0286] In the above embodiment, by providing a linkage device that is transmission-connected to the water pumping device, the sewage in the dehydration chamber 102 is discharged into the cleaning chamber 101 when the mop plate moves along the stroking extrusion mechanism 901 to swipe water.

[0287] In some embodiments, as Figures 1-4 As shown, the linkage device includes a rotatably arranged driving member 3 and a transmission structure, and the transmission structure is respectively connected to the driving member 3 and the pumping device; when the mop plate moves along the stroking and squeezing mechanism 901, the driving member 3 is driven to rotate, thereby driving the transmission structure to drive the pumping device to discharge the sewage in the dehydration chamber 102 into the cleaning chamber 101.

[0288] Specifically, the driving member 3 can be configured as a rotation driving structure such as a gear or a wheel, and the specific connection form of the corresponding transmission connection can be a gear transmission connection, a force transmission connecting rod transmission connection, etc.

[0289] In some embodiments, as Figures 1-4 As shown, the transmission structure includes a gear module. When the driving member 3 rotates, it drives the gear module to operate. The operation of the gear module drives the pumping device to discharge the sewage in the dehydration chamber 102 into the cleaning chamber 101.

[0290] In the above embodiment, a gear module is provided between the driving member 3 and the pumping device, and the labor-saving characteristics of the gear module transmission connection are utilized to help the mop plate move along the stroking extrusion mechanism 901 to drive the driving member 3, thereby improving the pumping efficiency of the pumping device, and further improving the drainage efficiency of discharging the sewage in the dehydration chamber 102 into the cleaning chamber 101.

[0291] In some embodiments, as Figures 1-4 As shown, the gear module includes a first gear 4 that is transmission-connected to the driving member 3, and the first gear 4 is transmission-connected to the pumping device; when the driving member 3 rotates, it drives the first gear 4 to rotate, and the rotation of the first gear 4 drives the pumping device to discharge the sewage in the dehydration chamber 102 into the cleaning chamber 101.

[0292] Specifically, since the first gear 4 is transmission-connected to the water pumping device, in the intermediate structural member of the transmission connection, the part transmission-connected to the first gear 4 can be set as a gear, and the part transmission-connected to the water pumping device can be set as a force transmission connecting rod.

[0293] In some embodiments, as Figures 1-4 As shown, the gear module also includes a second gear 5 meshing with the first gear 4, and the second gear 5 is connected to the pumping device; the rotation of the first gear 4 drives the second gear 5 to rotate; the rotation of the second gear 5 drives the pumping device to discharge the sewage in the dehydration chamber 102 into the cleaning chamber 101.

[0294] Specifically, the diameter of the first gear 4 is smaller than that of the second gear 5, so that the first gear 4 and the second gear 5 have a smaller transmission ratio when they are engaged and transmitted, but the labor-saving efficiency is better, so as to help the mop plate move up and down along the stroking extrusion mechanism 901 to drive the driving member 3, thereby improving the pumping efficiency of the pumping device.

[0295] In some embodiments, as Figures 1-4 As shown, the first gear 4 is coaxially arranged with the driving member 3 .

[0296] Specifically, the first gear 4 is coaxially arranged with the driving member 3. When the mop plate moves up and down along the stroking and squeezing mechanism 901, the driving member 3 rotates synchronously with the first gear 4, so that the first gear 4 drives the second gear 5 meshing with it to rotate, thereby driving the water pumping device to work.

[0297] In some embodiments, as Figures 1-4 As shown, a first mounting plate 6 is further provided in the cleaning chamber 101 , and the driving member 3 and the first gear 4 are respectively provided on both sides of the first mounting plate 6 .

[0304] In the above embodiment, a plurality of elastic arms are provided at the second end of the rotating roller 7 to connect and cooperate with the driving member 3 , so as to improve the connection stability of the fixed connection between the driving member 3 and the rotating roller 7 .

[0305] In some embodiments, as Figures 1-4 As shown, a fixing groove is formed on one side of the driving member 3 close to the first mounting plate 6, and a plurality of mounting holes are provided on the bottom wall of the fixing groove; when the driving member 3 is sleeved and fixed on the outer periphery of the second end of the rotating roller 7, the plurality of elastic arms at the second end of the rotating roller 7 respectively penetrate into the plurality of mounting holes and engage with the plurality of mounting holes.

[0306] In the above embodiment, the multiple mounting holes in the fixing groove provide accommodation positions for the elastic arms, so that the multiple elastic arms are stably engaged with the multiple mounting holes, thereby enabling the driving member 3 to be stably fixedly connected to the rotating roller 7.

[0307] In some embodiments, as Figures 1-4 As shown, the rotating roller 7 is a hollow structure, and a cylindrical protrusion is provided at the center of the fixing groove. When the driving member 3 is sleeved and fixed on the outer periphery of the second end of the rotating roller 7, the cylindrical protrusion extends into the hollow structure of the rotating roller 7.

[0308] In the above embodiment, the hollow structure of the rotating roller 7 and the cylindrical protrusion in the center of the fixing groove in the driving member 3 are used to form a nested fit, thereby further improving the stable and fixed connection between the driving member 3 and the rotating roller 7.

[0316] In some embodiments, as Figures 1-4 As shown, the transmission structure includes a first gear 4 coaxially arranged with the driving member 3 and a second gear 5 meshing with the first gear 4; the second gear 5 is rotatably connected to the second mounting plate 8.

[0317] In the above embodiment, the second mounting plate 8 can also provide a mounting position for the second gear 5 , thereby achieving stable rotational mounting of the second gear 5 .

[0318] In some embodiments, as Figures 1-4 As shown, the driving member 3 and the first gear 4 are rotatably connected to the first mounting plate 6 through the rotating roller 7, and the rotating roller 7 is a hollow structure; the second mounting plate 8 is provided with a plug-in column, and the top of the plug-in column has multiple spring buckles. The plug-in column is inserted into the hollow area of ​​the rotating roller 7 and is clamped with the side wall of the hollow area.

[0320] In some embodiments, as Figures 1-4 As shown, one of the first mounting plate 6 and the second mounting plate 8 is provided with a buckle, and the other of the first mounting plate 6 and the second mounting plate 8 is provided with a slot; the buckle and the slot are connected so that the first mounting plate 6 is fixed to the second mounting plate 8.

[0321] In the above embodiment, the first mounting plate 6 and the second mounting plate 8 are stably mounted by the snap fit between the snap fasteners and the snap slots, so that a mounting area is formed between the first mounting plate 6 and the second mounting plate 8 .

[0322] In some embodiments, as Figures 1-4 As shown, the mop bucket is also provided with a mop bucket cover 9, which covers the opening of the mop bucket. The second mounting plate 8 is fixedly connected to the mop bucket cover 9 and extends along the moving direction of the mouth-smoothing and squeezing mechanism 901; or, the second mounting plate 8 is fixedly connected to the side wall of the mop bucket and extends along the moving direction of the mouth-smoothing and squeezing mechanism 901.

[0323] Specifically, the bucket cover 9 is arranged at the opening at the top of the bucket body 1 in the mop bucket, and the second mounting plate 8 is fixedly connected to the mop bucket cover 9 for installation and fixation, or the second mounting plate 8 is fixedly connected to the side wall of the mop bucket, that is, the side wall of the bucket body 1 for installation and fixation.

[0324] Furthermore, the mop bucket is also provided with a connecting plate, which is arranged between the second mounting plate 8 and the mop bucket cover 9, and is used to connect the second mounting plate 8 to the mop bucket cover 9.

[0325] Furthermore, a mounting groove is provided at one end of the connecting plate facing the second mounting plate 8, and a support platform is provided on the side wall of the mop bucket. A support block that cooperates with the mounting groove is provided on the support platform facing the stroking extrusion mechanism 901; the connecting plate is fixed on the support platform through the interference fit between the mounting groove and the support block.

[0326] In some embodiments, as Figures 1-4 As shown, the pumping device is fixedly mounted on the second mounting plate 8 and is in transmission connection with the second gear 5 .

[0327] In the above embodiment, the second mounting plate 8 provides an installation location for the water pumping device, ensuring that the water pumping device can operate stably.

[0328] In some embodiments, as Figures 1-4 As shown, the driving member 3 is a guide wheel or a gear. When the mop plate moves up and down along the stroking mouth squeezing mechanism 901 to swipe water, it abuts against the guide wheel or gear and drives the guide wheel or gear to rotate.

[0329] Specifically, when the driving member 3 is set as a guide wheel, the mop plate abuts against the guide wheel when it moves up and down along the stroking mouth squeezing mechanism 901 to stroke water, thereby relying on friction to drive the driving member 3 to rotate; when the driving member 3 is set as a gear, a rack meshing with the gear is correspondingly provided on the mop plate, and the gear and rack are meshed when the mop plate moves up and down along the stroking mouth squeezing mechanism 901 to stroke water, thereby the gear and rack meshing transmission drives the driving member 3 to rotate.

[0330] In some embodiments, as Figures 1-4 As shown, the mop plate abuts against the guide wheel when it moves up and down along the mop mouth squeezing mechanism 901 to pry water, and drives the guide wheel to rotate through the friction between the mop plate and the outer peripheral surface of the guide wheel. The outer peripheral surface of the guide wheel has a pattern that increases the friction; and / or, the outer periphery of the gear is provided with teeth with a triangular or trapezoidal cross-section.

[0332] In some embodiments, as Figures 1-4 As shown, the pumping device includes a negative pressure mechanism 10, and the linkage device is transmission-connected to the negative pressure mechanism 10. When the mop plate moves up and down along the stroking mouth squeezing mechanism 901 to swipe water, the linkage device is driven to drive the negative pressure mechanism 10 to discharge the sewage in the dehydration chamber 102 into the cleaning chamber 101.

[0333] In the above embodiment, the negative pressure mechanism 10 in the pumping device utilizes the negative pressure principle to pump water, thereby discharging the sewage in the dehydration chamber 102 into the cleaning chamber 101 .

[0334] In some embodiments, as Figures 1-4 As shown, the negative pressure mechanism 10 includes a rod body 1001, a piston 1002 and a piston tube 1003. One end of the rod body 1001 is connected to the piston 1002, and the other end is connected to the linkage device. When the mop plate moves up and down along the stroking mouth squeezing mechanism 901 to swipe water, the linkage device is driven to operate, and the operation of the linkage device drives the piston 1002 connected to the rod body 1001 to reciprocate in the piston tube 1003 to discharge the sewage in the dehydration chamber 102 into the cleaning chamber 101.

[0335] Specifically, the piston 1002 is interference fit with the inner wall of the piston tube 1003 and can move relative to the inside of the piston tube 1003. One end of the rod body 1001 is rotatably connected to the piston 1002, and the other end is rotatably connected to the linkage device.

[0336] In some embodiments, as Figures 1-4 As shown, the linkage device includes a driving member 3 and an output gear connected to the driving member 3. When the mop plate moves up and down along the stroking mouth squeezing mechanism 901 to swipe water, the driving member 3 is driven to rotate, and the rotation of the driving member 3 drives the output gear to rotate; the output gear is the gear that outputs power of the linkage device; one end of the rod body 1001 is connected to the piston 1002, and the other end is connected to the non-center position of the output gear. The rotation of the output gear drives the piston 1002 connected to the rod body 1001 to reciprocate in the piston tube 1003.

[0337] Specifically, the output gear is the second gear 5; the connection position between the rod body 1001 and the output gear is located on the non-center end face of the output gear, so that the rotation of the output gear can drive the rod body 1001 to reciprocate, so that the negative pressure mechanism 10 can pump water.

[0338] Furthermore, the linkage device includes a driving member 3 and an output gear connected to the driving member 3. When the mop plate moves along the stroking mouth squeezing mechanism 901 to swipe water, the driving member 3 is driven to rotate, and the driving member 3 rotates to drive the output gear to rotate; the output gear is the gear that outputs power of the linkage device; one end of the rod body 1001 is connected to the piston 1002, and the other end is provided with a rack and meshes with the output gear. The rotation of the output gear drives the piston 1002 connected to the rod body 1001 to move in the piston tube 1003.

[0339] Furthermore, the water outlet 202 is arranged toward the stroking and squeezing mechanism 901 .

[0340] Furthermore, a detachable grille cover is provided at the end of the water outlet 202 .

[0341] Furthermore, the pumping device includes a tee 11, which is connected to the water outlet 202, the water inlet 201 and the negative pressure mechanism 10 respectively; the tee 11 is extended along the direction in which the mop plate is inserted into the stroking and squeezing mechanism 901, and the water outlet 202 is formed at one end of the tee 11 close to the stroking and squeezing mechanism 901, and the end of the tee 11 away from the stroking and squeezing mechanism 901 is connected to the pipe 2, and the end of the pipe 2 away from the tee 11 forms the water inlet 201, and the middle part of the tee 11 is connected to the negative pressure mechanism 10.

[0342] Furthermore, the end of the pipe 2 forming the water inlet 201 is extended toward the bottom of the dehydration chamber 102 to facilitate the discharge of sewage at the bottom of the dehydration chamber 102 .

[0343] Furthermore, if Figure 5 As shown, the three-way member 11 is also provided with an inlet check valve 12 corresponding to the water inlet 201 and a water outlet check valve 13 corresponding to the water outlet 202. When the negative pressure mechanism 10 is pumping water, the inlet check valve 12 opens and the water outlet check valve 13 closes. When the negative pressure mechanism 10 is draining water, the inlet check valve 12 closes and the water outlet check valve 13 opens, thereby draining the sewage in the dehydration chamber 102 into the cleaning chamber 101. The inlet check valve 12 and the water outlet check valve 13 include an aperture and a valve ball. The diameter of the valve ball is larger than the diameter of the aperture. When sewage flows through the aperture, it can drive the valve ball to close or open the aperture.

[0344] In some embodiments, as Figures 1-4 As shown, the mop bucket is also provided with a driven part 14 corresponding to the linkage device; when the mop board moves up and down along the stroking mouth squeezing mechanism 901 to stroke water, one side of the mop board drives the linkage device to operate, and the driven part 14 abuts against the other side of the mop board to provide support force to the mop board.

[0345] In the above embodiment, the driven member 14 abuts against the other side of the mop board to provide support force to the mop board, so that the driven member 14 and the driving member 3 cooperate with each other to limit the mop board, thereby improving the stability of the mop board in moving up and down.

[0346] Specifically, when the mop plate moves up and down along the stroking mouth squeezing mechanism 901 to swipe water, the mop plate is located between the driven member 14 and the driving member 3 to operate.

[0347] Furthermore, the driven component 14 can be configured as a fixed protruding structure or a rotating structure.

[0348] In some embodiments, as Figures 1-4 As shown, the driven member 14 is a rotating wheel arranged opposite to the linkage device; when the mop plate moves up and down along the stroking mouth squeezing mechanism 901 to swipe water, the other side of the mop plate drives the rotating wheel to rotate.

[0349] In the above embodiment, the rotating wheel can rotate when the mop plate moves up and down along the stroking mouth squeezing mechanism 901 to swipe water, thereby further improving the stability of the mop plate moving up and down.

[0350] In some embodiments, as Figures 1-4 As shown, the mop bucket also includes a first mounting plate 6, which extends along the direction in which the mop plate is inserted into the stroking and squeezing mechanism 901 and is arranged below the restraining side of the stroking and squeezing mechanism 901; the rotating wheel is rotatably arranged on the first mounting plate 6.

[0351] In the above embodiment, the first mounting plate 6 provides a mounting position for the rotating wheel.

[0352] In some embodiments, as Figures 1-4 As shown, the first mounting plate 6 is provided with a connecting roller 15 , and a through hole is provided at the center of the rotating wheel. The connecting roller 15 is inserted into the through hole so that the rotating wheel rotates relative to the connecting roller 15 .

[0353] In the above embodiment, the rotating wheel is installed by means of the connecting roller 15 rotatably engaged with the through hole, so that the rotating wheel is rotatably installed on the first mounting plate 6 .

[0354] In some embodiments, as Figures 1-4 As shown, a snap-fit ​​buckle is provided at the top end of the connecting roller 15 , and the connecting roller 15 is inserted into the through hole of the rotating wheel, and the snap-fit ​​buckle is snap-fitted with the side wall of the through hole.

[0355] In the above embodiment, the snap buckle is snapped into engagement with the side wall of the through hole, so that the driven component 14 , ie, the rotating wheel, and the connecting roller 15 are stably and fixedly connected.

[0356] Specifically, the rotating wheel is a gear. When the mop plate moves up and down along the mop mouth squeezing mechanism 901 to pry water, the rotating wheel set as a gear is engaged with another rack provided on the mop plate.

[0357] In some embodiments, as Figures 1-4 As shown, the side wall of the through hole is provided with an annular boss, and the snap buckle is snapped into engagement with the annular boss.

[0358] The working process is as follows:

[0359] When the mop plate moves up and down along the stroking mouth squeezing mechanism 901 to stroke water, the two sets of racks of the mop plate form a gear meshing transmission with the driving member 3 and the driven member 14 respectively.
