Description

Technical Field

[0001] The present invention relates to a cleaning tool, and more particularly to a sewage-separating mop cleaning bucket suitable for cleaning and dewatering a hand-pressed rotary flat mop. Background Art

[0002] For this reason, the applicant invented a utility model patent application "A Water-saving Mop Bucket" with a patent number of CN201720525401.8 (publication number CN207785091U), which discloses a non-lifting cleaning and wringing bucket, including a bucket body. A transmission shaft for supporting a mop head with a wiping material at the bottom is provided in the bucket body, and the transmission shaft can make the mop head placed thereon rotate. The characteristics are as follows: An inwardly concave accommodating cavity is provided at the bottom in the bucket body, and a box body is embedded in the accommodating cavity. A water pump and a control structure are provided in the box body. A cleaning component is also provided in the bucket body to clean the wiping material at the bottom of the mop head rotating in the bucket body. Whether the water pump sprays water towards the wiping material at the bottom of the mop head is controlled by the control structure. To achieve sewage separation, the bucket body has a clean water cavity and a sewage cavity that are independent and blocked from each other. Two inwardly concave cavities are provided at the bottom in the bucket body, and the two cavities form the sewage cavity. A water tank is detachably installed in the bucket body. The water pump is directly provided in the water tank, and the inner cavity of the water pump constitutes the clean water cavity. An inlet channel is provided on the outer shell of the water pump and communicates with the inner cavity of the water tank. A switch structure capable of closing the inlet channel is provided on the inlet channel. The water tank has an outlet channel and a water injection port. A first one-way valve that remains normally closed is provided in the outlet channel, and a second one-way valve that remains normally closed is provided in the inlet channel. In the state where the water tank is installed on the bucket body, the first one-way valve and the second one-way valve push against each other. The first one-way valve opens the outlet channel of the water tank, and at the same time the second one-way valve opens the inlet channel of the clean water cavity, and the outlet channel of the water tank and the inlet channel of the clean water cavity are butted and communicated. After the water tank is installed, the outlet channel of the water tank is automatically connected to the inlet channel of the clean water cavity, and the clean water cavity is replenished with water by the water pre-stored in the water tank. When the water tank is removed, both the outlet channel of the water tank and the inlet channel of the clean water cavity are automatically closed. The outlet channel of the water tank is closed for filling water into the water tank, and the closing of the inlet channel of the clean water cavity prevents dirty water from entering the clean water cavity and also prevents excess water from flowing out of the clean water cavity. The design is reasonable and convenient to use.

[0003] Although it can achieve sewage separation, it requires an additional configuration of a water tank, and there is an auxiliary one-way valve structure directly between the water tank and the clean water cavity, with a complex structure and easy leakage at the joint. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a sewage-separating mop cleaning bucket with a simpler and more reasonable structural layout that can achieve cleaning and wringing in place, and the cleaning bucket can independently clean the mop head with full clean water multiple times after being filled with clean water once.

[0005] The technical solution adopted by the present invention to solve the above technical problems is as follows: A cleaning bucket for a dirt-removing and separating mop, comprising a bucket body having a clear water chamber and a sewage chamber that are independent of each other and blocked. A transmission shaft for connecting a mop head and a water spraying mechanism for spraying water on a wiping material on the mop head are provided in the bucket body. The water spraying mechanism includes a wheel cover, a pump wheel, and a water spraying channel. It is characterized in that: The clear water chamber is inseparable from the bucket body. The clear water chamber is divided into a water replenishing clear water chamber and a quantitative clear water chamber located below the water replenishing clear water chamber. The first water filling volume of the water replenishing clear water chamber is more than twice the second water filling volume of the quantitative clear water chamber. The water replenishing clear water chamber and the quantitative clear water chamber are communicated through a water replenishing channel. A control member for controlling the water replenishing speed of the quantitative clear water chamber is provided at the water replenishing channel. The pump wheel is arranged in the quantitative clear water chamber. The wheel cover covers the pump wheel. The inner cavity of the wheel cover is communicated with the quantitative clear water chamber and can intake water. The inner cavity of the wheel cover is communicated with the water spraying channel through a water outlet on the wheel cover. Water spraying holes are provided on the water spraying channel. The lower end of the transmission shaft is coaxially connected with the pump wheel, and the upper end of the transmission shaft exposes out of the sewage chamber.

[0006] If the volume ratio is too large, the volume of the bucket body will be too large, which is not conducive to storage. At the same time, it is heavy and inconvenient to use. If the volume ratio is too small, the number of cleaning times will be reduced. Therefore, preferably, the first water filling volume of the water replenishing clear water chamber is 3 to 5 times the second water filling volume of the quantitative clear water chamber. In this way, a good balance is achieved between the volume of the bucket body and the cleaning efficiency.

[0007] Further improvement: An annular wall extending upward is provided in the bucket body to form a first concave cavity in the bucket body. The bottom surface of the first concave cavity has a second concave cavity further recessed downward. The mouth end of the second concave cavity is covered with a second cover plate so that the second concave cavity forms the quantitative clear water chamber. The water replenishing channel is provided on the second cover plate; the mouth end of the first concave cavity is covered with a first cover plate so that the first concave cavity between the first cover plate and the second cover plate forms the water replenishing clear water chamber. This structure quickly forms a sewage chamber, a water replenishing clear water chamber, and a quantitative clear water chamber in the bucket body through the annular wall and two cover plates formed integrally in the bucket body, without the need to additionally provide a water tank, reducing costs. When adding water, just open the first cover plate, and the operation is very convenient. The setting of the annular wall makes the sewage chamber surround the clear water chamber, increasing the sewage storage capacity.

[0008] Even further improvement: The bottom surface of the second concave cavity has a third concave cavity further recessed downward. The pump wheel is arranged in the third concave cavity. The pump wheel in this structure is located below the quantitative clear water chamber, which can ensure that the clear water in the quantitative clear water chamber is pumped out as much as possible.

[0009] Further improvement: The top surface of the above-mentioned second cover plate has a second boss portion extending upward, and the transmission shaft vertically penetrates the second boss portion. The second boss portion extends upward, and the transmission shaft is vertically arranged through the second boss portion. The gap between the transmission shaft and the second boss portion is located at the top of the water replenishing and cleaning water cavity. In this way, even if there is no additional sealing structure between the transmission shaft and the second boss portion, it is ensured that the water in the water replenishing and cleaning water cavity will not flow in from the connection between the transmission shaft and the second cover plate. The setting of the second boss portion also facilitates holding by hand to remove the second cover plate from the mop bucket.

[0010] Further improvement: The top surface of the above-mentioned first cover plate has a first boss portion extending upward, and the upper end of the transmission shaft penetrates the first boss portion. The first boss portion is higher than the top surface of the first cover plate, playing a role in blocking water and effectively preventing the dirty water on the top surface of the first cover plate from flowing into the water replenishing and cleaning water cavity from the joint between the transmission shaft and the first cover plate.

[0011] Even further improvement: The above-mentioned second boss portion is flat. The upper end of the second boss portion is inserted into the first boss portion, and a buckle structure is provided between the outer wall of the second boss portion and the inner wall of the first boss portion. The upper end of the second boss portion is inserted into the first boss portion, and the second boss portion is flat, so that a rotation limiting structure is formed between the first cover plate and the second cover plate, preventing the first cover plate from rotating and making the cleaning bucket work more stably.

[0012] Preferably, the above-mentioned control member is a switch structure that determines whether the water replenishing and cleaning water cavity is communicated with the quantitative cleaning water cavity. The trigger end of the switch structure sequentially penetrates upward through the top surfaces of the second boss portion and the first boss portion; when the mop head is connected to the transmission shaft, the switch structure is triggered by the mop head to close the water replenishing channel, and the water replenishing and cleaning water cavity cannot or reduces the water replenishment to the quantitative cleaning water cavity, ensuring that the amount of water sprayed onto the wiping object gradually decreases; when the mop head is separated from the transmission shaft, the switch structure resets to open the water replenishing channel. Through the setting of the switch structure, the amount of water sprayed onto the wiping object by the water spraying holes per unit time is controlled. During operation, since the water replenishing channel for replenishing water to the quantitative cleaning water cavity is blocked by the switch structure, water cannot enter the quantitative cleaning water cavity. As the water in the quantitative cleaning water cavity becomes less and less, the amount of water sprayed out decreases accordingly. If the water in the quantitative cleaning water cavity is pumped out, the water spraying holes will no longer spray water onto the wiping object, and the wiping object is dried by the high-speed rotation of the mop head. Of course, there can be various implementation methods for the control member, and it can also be a blocking structure that reduces the water inlet speed. For example, the control member can also be a filtering component provided at the water inlet end of the water spraying mechanism, or a lid with small holes provided at the water inlet end of the water spraying mechanism.

[0013] Specifically, the above-mentioned switch structure includes a switch component that can slide up and down inside the second boss portion, and an elastic body is provided in the quantitative clean water cavity to keep the switch component in an upward movement trend; when the mop head is connected to the transmission shaft, the switch component is pressed down by the mop head and moves downward to block the water replenishing channel, and when the mop head is detached from the transmission shaft, the switch component moves upward under the action of the elastic body to open the water replenishing channel.

[0014] For further improvement, a contact component that forms rolling friction with the wiping object is provided at the top of the above-mentioned switch component. Rolling friction can ensure that the mop head rotates more easily. The contact component can be a roller, a steel ball or a cylindrical roller.

[0015] As a preferred structure of the water spraying channel, it includes an axial flow channel and a radial flow channel. The axial flow channel is provided on the second cover plate, the radial flow channel is provided on the first cover plate, the lower end of the axial flow channel is inserted and communicated with the water outlet on the wheel cover, the upper end of the axial flow channel is connected to the radial flow channel, and the water spraying holes are provided on the radial flow channel. This water spraying channel is arranged on the first cover plate and the second cover plate, which is convenient for manufacturing and assembly. Among them, the axial flow channel can be directly formed on the second cover plate or can be a pipe fitting inserted on the second cover plate.

[0016] As an improvement, the above-mentioned second cover plate and the wheel cover are detachably connected together through a buckle structure. In this way, the wheel cover and the second cover plate can be pre-connected together to form a module, ensuring that the water outlet on the wheel cover is aligned and inserted and communicated with the lower end of the axial flow channel, and then installed into the barrel body together, which is more convenient for assembly.

[0017] For further improvement, an annular wall extends outward from the above-mentioned radial flow channel, and an indicating water flow channel for partially guiding the water in the radial flow channel to the sewage cavity is provided at the radial flow channel outside the annular wall. The user can directly observe whether water flows out of the indicating water flow channel. If water flows out, it indicates that it is in the water spraying and cleaning stage, and if no water flows out, it indicates that it is in the drying stage, which can accurately control the cleaning time of the mop.

[0018] Further improvement, the first cover plate is provided with a cleaning component, and the cleaning component is used to clean the wiping material at the bottom of the mop head rotating in the barrel. The cleaning component can be a brush holder containing bristles, and the cleaning operation is achieved by scraping the bristles with the rotating wiping material. In this way, the dirt adhering to the wiping material can be scraped off better, and the cleaning effect is better. Of course, the cleaning component can also be a scraping bar or a squeezing roller, and the cleaning operation is achieved by squeezing the scraping bar or the squeezing roller with the rotating wiping material. Because the wiping material on the bottom surface of the mop head is uneven, or the thickness of the wiping material is different, in order to avoid that the part of the wiping material cannot be brushed by the bristles, further improvement, the lower part of the above-mentioned bristle holder is swingably arranged on the first cover plate, and the bristle holder is kept in an upward swinging trend by the elastic structure to ensure that the bristles are in full contact with the wiping material; or, the bristle holder is floated in the shell of the water spraying mechanism, and the bristle holder is kept in an upward moving trend by the elastic structure to ensure that the bristles are in full contact with the wiping material. In this way, the bristles can swing in a targeted manner to ensure full contact with the wiped object, thereby improving the cleaning effect of the bristles.

[0019] As a further improvement, a sealing ring is provided between the second cover plate and the second concave cavity, and the second cover plate is constrained in the second concave cavity by a rotary clamp structure. The second cover plate fixed in the second concave cavity by a rotary clamp can compress the sealing ring, and the setting of the sealing ring can better separate the quantitative clean water chamber and the replenishing clean water chamber, so that the quantitative clean water chamber and the replenishing clean water chamber can only be connected through the replenishing water channel.

[0020] Preferably, the top surface of the first cover plate is tilted downward from the center to the surrounding directions, so that the dirty water flowing to the top surface of the first cover plate can be quickly discharged to the sewage chamber, and the sewage can be better prevented from entering the water replenishment and clean water chamber.

[0021] As a further improvement, the periphery of the first cover plate has a rotation-limiting dowel extending downward, and the outer periphery of the annular wall is provided with a rotation-limiting slot for the rotation-limiting dowel to be inserted into. This structure has rotation-limiting and fool-proofing functions, and can clearly indicate to customers whether the first cover plate is installed in place during use. If the fool-proof dowel is in a position misaligned with the fool-proofing slot, it indicates that the first cover plate is not installed in place. If the fool-proof dowel is in a position inserted into the fool-proofing slot, it indicates that the first cover plate is installed in place and the water spray channel is in a position that is connected to the inner cavity of the wheel cover.

[0022] As an improvement, the transmission shaft is composed of a joint and a pump wheel shaft provided on the pump wheel and extending upward. A fixed shaft is fixed to the bottom of the quantitative clean water chamber. The pump wheel shaft is sleeved on the fixed shaft through a bearing or a sleeve. The joint is connected to the top of the pump wheel shaft, and the joint is used for transmission connection with the mop head. The connection is a hard connection, which can be a threaded connection or a welded connection, or the transmission shaft and the impeller shaft can be an integrally formed part. This structure can make the transmission shaft rotate easily, and the setting of the fixed shaft provides a suitable installation position for the transmission shaft.

[0023] To make the transmission shaft rotate more easily, steel balls for supporting the inner top surface of the joint are provided at the top of the above-mentioned fixed shaft.

[0024] Compared with the prior art, the advantages of the present invention are as follows:

[0025] 1. The clear water chamber is divided into a water replenishing clear water chamber located in the upper part and a quantitative clear water chamber located in the lower part. There is no need to additionally set up a water tank. The water replenishing clear water chamber is located above the quantitative clear water chamber, which is conducive to replenishing water to the quantitative clear water chamber; the amount of water consumed in one cleaning operation is the water volume of the second water filling volume of the quantitative clear water chamber, and the first water filling volume of the water replenishing clear water chamber is 2 to 6 times that of the second water filling volume of the quantitative clear water chamber. In this way, when the water replenishing clear water chamber is filled with water at one time, it can enter and fill the quantitative clear water chamber in multiple times, that is, 2 to 6 cleaning operations can be carried out.

[0026] 2. The water replenishing clear water chamber and the quantitative clear water chamber are connected through a water replenishing channel, and a control member for controlling the water inlet speed of the quantitative clear water chamber is provided at the water replenishing channel. When the mop head is connected to the transmission shaft, the control member works, so that the water outlet speed of the quantitative clear water chamber is greater than its water inlet speed. At the beginning, the water spraying amount is large, and the amount of water obtained on the wiping object is greater than the water wringing amount. This process is the cleaning process. The water spraying amount gradually decreases, and the water wringing amount is greater than the amount of water obtained on the wiping object. This process is the water wringing process. Since both cleaning and dehydration are completed at the same position, there is no need to separately set a cleaning position and a water wringing position in the bucket body, which makes the volume of the entire bucket body much smaller compared with the traditional mop head.

[0027] 3. The rotation of the mop head drives the transmission shaft and the pump wheel to rotate coaxially together. There is no need to additionally sleeved a rotating bracket for driving the mop head to rotate on the transmission shaft, and there is no need to set up a speed reduction mechanism. At the same time, the water pressing component is directly driven by the rotation of the transmission shaft, and there is no need to set up an acceleration mechanism between the water pressing component and the transmission shaft. Therefore, the structure of this cleaning tool is greatly simplified and the cost is also greatly reduced. Through continuous experiments, the simplified version of the structure can also achieve good water spraying and scraping effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The present invention will be further described in detail below in conjunction with the embodiments with reference to the drawings.

[0037] As Figures 1 to 8 shown, this is a preferred embodiment of the present invention.

[0038] A sewage cleaning and separating mop cleaning bucket is used in conjunction with a hand-pressed rotary mop. The hand-pressed rotary mop is a prior art. The hand-pressed rotary mop includes an upper rod and a lower rod sleeved with each other. A driving structure is provided between the upper and lower rods to convert the telescopic movement of the upper rod into the rotary movement of the lower rod. A mop head 4 with a wiping material 41 is connected to the lower end of the lower rod. The wiping material 41 can be a dishcloth or the like. The mop head 4 is a flat mop head, and the flat mop head can be disc-shaped or rectangular-shaped.

[0039] The sewage cleaning and separating mop cleaning bucket includes a bucket body 1 having a sewage chamber 1a and a clean water chamber that are independent and blocked from each other. A transmission shaft 3 for connecting the mop head 4 and a water spraying mechanism for spraying water on the wiping material 41 on the mop head 4 are provided in the bucket body 1. The water spraying mechanism includes a wheel cover 5, a pump wheel 6, and a water spraying channel 7. The transmission shaft 3 is composed of a joint 31 and a pump wheel shaft 32 provided on the pump wheel 6 and extending upward. A fixed shaft 16 is fixed to the bottom of the quantitative clean water chamber 1c. The pump wheel shaft 32 is sleeved on the fixed shaft 16 through a bearing or a bushing. The joint 31 is connected to the top end of the pump wheel shaft 32, and the connection is a rigid connection, which can be a threaded connection, a welded connection, or an integrally formed connection. The joint 31 is used for driving connection with the mop head 4. A steel ball 17 for supporting the inner top surface of the joint 31 is provided at the top of the fixed shaft 16.

[0040] The clear water chamber is inseparable from the barrel body 1. The clear water chamber is divided into a water replenishing clear water chamber 1b and a quantitative clear water chamber 1c located below the water replenishing clear water chamber 1b. The first water filling volume Q1 of the water replenishing clear water chamber 1b is more than 2 times, preferably 3 to 5 times, of the second water filling volume Q2 of the quantitative clear water chamber 1c. The water replenishing clear water chamber 1b and the quantitative clear water chamber 1c are communicated through a water replenishing channel 1d. A control member 2 for controlling the water replenishing speed of the quantitative clear water chamber 1c is provided at the water replenishing channel 1d. A pump impeller 6 is arranged in the quantitative clear water chamber 1c. The wheel cover 5 covers the pump impeller 6. The inner cavity of the wheel cover 5 is communicated with the quantitative clear water chamber 1c and can intake water. The inner cavity of the wheel cover 5 is communicated with a water spraying channel 7 through a water outlet 51 on the wheel cover 5. A water spraying hole 71 is provided on the water spraying channel 7. The lower end of the transmission shaft 3 is coaxially connected with the pump impeller 6. The upper end of the transmission shaft 3 exposes out of the sewage chamber 1a. In the state where the mop head 4 is connected to the transmission shaft 3, the connection is generally sleeved on the transmission shaft and driven by the way of inserting and matching through rib grooves. The rotation of the mop head 4 drives the transmission shaft 3 and the pump impeller 6 to rotate coaxially together. The rotating pump impeller 6 pumps water out through the water outlet 51 and the water spraying channel 7 and then sprays the water to the wiping object 41 through the water spraying hole 71. And the control member 2 works to make the water outlet speed of the quantitative clear water chamber 1c greater than its water replenishing speed.

[0041] An annular wall 14 extending upward is provided in the barrel body 1 to form a first concave cavity 11 in the barrel body. The bottom surface of the first concave cavity 11 has a second concave cavity 12 further recessed downward. The mouth end of the second concave cavity 12 is covered with a second cover plate 9 so that the second concave cavity 12 forms the quantitative clear water chamber 1c. The water replenishing channel 1d is provided on the second cover plate 9. At the same time, the second cover plate 9 and the wheel cover 5 are detachably connected together through a buckle structure. The mouth end of the first concave cavity 11 is covered with a first cover plate 8 so that the first concave cavity 11 between the first cover plate 8 and the second cover plate 9 forms the water replenishing clear water chamber 1b.

[0042] The bottom surface of the second concave cavity 12 has a third concave cavity 13 further recessed downward. Specifically, the pump impeller 6 is arranged in the third concave cavity 13. The top surface 82 of the first cover plate 8 is inclined downward from the center to the surrounding direction. The peripheral edge of the first cover plate 8 has a downward extending rotation limiting insertion rib 83. A rotation limiting slot 141 for inserting the rotation limiting insertion rib 83 is provided on the outer periphery of the annular wall 14.

[0043] The top surface of the second cover plate 9 has an upward extending second boss portion 91. The transmission shaft 3 vertically penetrates through the second boss portion 91. The top surface of the first cover plate 8 has an upward extending first boss portion 81. The upper end of the transmission shaft 3 penetrates through the first boss portion 81. The second boss portion 91 is flat. The upper end of the second boss portion 91 is inserted into the first boss portion 81. And a buckle structure is provided between the outer wall of the second boss portion 91 and the inner wall of the first boss portion 81.

[0044] The control member 2 in this embodiment is a switch structure that determines whether the water replenishing clear water chamber 1b is communicated with the quantitative clear water chamber 1c. The trigger end of the switch structure sequentially penetrates upward through the top surfaces of the second boss portion 91 and the first boss portion 81; when the mop head 3 is connected to the transmission shaft 3, the switch structure is triggered by the mop head 4 to close the water replenishing channel 1d, and the water replenishing clear water chamber 1b cannot or reduces the water replenishment to the quantitative clear water chamber 1c, ensuring that the amount of water sprayed onto the wiping object 41 gradually decreases; when the mop head 4 is separated from the transmission shaft 3, the switch structure resets to open the water replenishing channel 1d.

[0045] The switch structure includes a switch member 21 that can slide up and down in the second boss portion 91, and an elastic body 22 is provided in the quantitative clear water chamber 1c to keep the switch member 21 in an upward movement trend; when the mop head 4 is connected to the transmission shaft 3, the switch member 21 is pressed down by the mop head 4 and moves downward so that the lower end of the switch member 21 blocks the water replenishing channel 1d, and when the mop head 4 is separated from the transmission shaft 3, the switch member 21 moves upward under the action of the elastic body 22 so that the lower end of the switch member 21 opens to the water replenishing channel 1d. A contact member 23 that forms a rolling friction with the wiping object 41 is provided at the top end of the switch member 21.

[0046] The water spraying channel 7 includes an axial flow channel 7a and a radial flow channel 7b. The axial flow channel 7a is provided on the second cover plate 9. A sealing ring 15 is provided between the second cover plate 9 and the second cavity 12, and the second cover plate 9 is constrained in the second cavity 12 through a snap structure. The radial flow channel 7b is provided on the first cover plate 8. The lower end of the axial flow channel 7a is inserted and communicated with the water outlet 51 on the wheel cover 5, and the upper end of the axial flow channel 7a is inserted and communicated with the radial flow channel 7b. The water spraying holes 71 are provided on the radial flow channel 7b. The radial flow channel 7b extends outwards to form an annular wall 14, and an indicating water flow channel 7c that partially leads the water in the radial flow channel 7b to the sewage chamber 1a is provided at the radial flow channel 7b outside the annular wall 14.

[0047] A cleaning member 10 is provided on the first cover plate 8, and the cleaning member 10 is used to clean the wiping object 41 at the bottom of the mop head 4 rotating in the barrel body 1. The cleaning member 10 is radially arranged with the axis of the transmission shaft 3 as the center, and the cleaning member 10 covers the wiping object 41 along the radial direction on one side of the center of the mop head 4 from the inside to the outside.

[0048] The working principle and process of this cleaning tool are as follows:

[0049] Cleaning and dehydration process: Open the first cover plate 8, pour clean water into the water replenishment cavity 1b until it reaches an appropriate height. At this time, since the mop head 4 is not connected to the transmission shaft 3, the lower end of the switch component 21 opens to the water replenishment channel 1d, and the clean water in the water replenishment cavity 1b fills the metered clean water cavity 1c through the water replenishment channel 1d, then cover the first cover plate 8. Then connect the mop head 4 to the transmission shaft 3. At this time, the switch component 21 is pressed down by the mop head 4 and moves downward, so that the lower end of the switch component 21 blocks the water replenishment channel 1d, and no longer or only a small amount of water is replenished into the metered clean water cavity 1c. Operate the mop rod to drive the transmission shaft 3 and the mop head 4 to rotate synchronously and coaxially. The transmission shaft 3 drives the pump wheel 6 to rotate. The rotating pump wheel 6 pumps the clean water through the water outlet 51 and the water spraying channel 7 and then sprays it onto the wiping object 41 through the water spraying holes 71. During the whole process, no longer or only a small amount of water is replenished into the metered clean water cavity 1c. As the mop head 4 rotates, the water in the metered clean water cavity 1c becomes less and less. At the beginning, the water spraying amount is large, and the water obtained on the wiping object 41 is greater than the dehydration amount. This process is the cleaning process. The water spraying amount gradually decreases. After the water in the metered clean water cavity 1c is used up or basically used up, the pump wheel 6 idles, and the water spraying holes 71 no longer spray water or spray very little water. Therefore, the wiping object 41 is only dehydrated, or the dehydration amount of the wiping object 41 is greater than the water obtained on the wiping object 41. This process is the dehydration process.

[0050] Since both cleaning and dehydration are completed at the same position, there is no need to separately set a cleaning position and a dehydration position inside the barrel, which greatly reduces the volume of the whole barrel compared with the traditional mop head.

[0051] After the work is completed, remove the mop head from the transmission shaft 3. The switch component 21 moves upward and resets under the action of the elastic body 22. The lower end of the switch component 21 opens to the water replenishment channel 1d, and the clean water in the water replenishment cavity 1b replenishes the metered water cavity 1c again through the water replenishment channel 1d for the next operation.

[0052] If you want to clean the pump wheel 6, just open the second cover plate 9, and then you can take out the pump wheel 6 for cleaning.

[0053] It should be noted that in the description of this embodiment, the orientation or positional relationship indicated by terms such as "front, back", "left, right", "up, down", etc. are all based on the orientation or positional relationship shown in the drawings.
