Description

Technical Field

[0001] This invention relates to the field of cleaning tools, and more specifically to a cleaning tool. Background Technology

[0002] Nowadays, mops are widely used as a common cleaning tool and are often used in conjunction with mop buckets. Currently, there are structures where the mop handle and mop stick are connected, the handle can rotate relative to the mop bucket, and the bucket also has water spray holes and scraping components, so that the mop bucket can spray water onto the bottom of the handle while scraping the handle and mop to achieve cleaning.

[0003] However, with this cleaning method, the water nozzles near the outer edge may not be covered by the drain plate, allowing clean water to easily spray out of the bucket, greatly affecting the user experience. Existing technology uses angled nozzles to adjust the water direction, thus preventing water from spraying out of the bucket.

[0004] However, with this setup, when the mop head is not circular, the water sprayed from the angled nozzles will still bypass the mop head and hit the inner wall of the mop bucket, potentially causing cleaning water to splash out of the mop bucket and affecting the user experience. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect that when the shape of the mop head is not circular, the water coming out of the nozzle will bypass the mop head and spray onto the inner wall of the mop bucket and splash out of the mop bucket, affecting the user experience, thereby providing a cleaning tool.

[0006] In a first aspect, the present invention provides a cleaning tool, comprising: a mop, including a handle and a mop head, the mop head including a mop plate, the mop plate being movably connected to the lower end of the handle, the mop plate also having a rotating connecting portion, the mop plate having unequal diameters from the rotating connecting portion to the edge of the mop plate; a mop bucket, having a built-in water supply structure and a water outlet bracket, the top side of the water outlet bracket having a rotating engagement structure, the mop plate being detachably and movably connected to the rotating engagement structure via the rotating connecting portion, suitable for rotating relative to the water outlet bracket about the rotating connecting portion under the action of an external force; the top side of the water outlet bracket also having a water outlet device, the water outlet device comprising: a housing including a cleaning surface and a water connecting portion, the cleaning surface having a cleaning state relative to the mop plate; at least one water outlet hole, communicating with the water connecting portion and opened on the cleaning surface near the rotating engagement structure, suitable for being completely covered by the projection of the mop plate on the cleaning surface in the cleaning state.

[0007] Beneficial effects:

[0008] By incorporating a rotating connection and a water outlet device, the mop head and the water outlet bracket equipped with the device can rotate relative to each other. Furthermore, the water outlet holes on the water outlet device are completely covered by the projection of the mop head onto the cleaning surface. During cleaning, as the mop head rotates relative to the water outlet bracket, its projection onto the cleaning surface also rotates, completely covering the water outlet holes. This design prevents water from spraying out of the gaps created by the non-circular shape of the mop head during rotation, thus improving the user experience. It overcomes the shortcomings of existing technologies where, when the mop head is non-circular, water from the nozzle bypasses the mop head, hits the inner wall of the mop bucket, and splashes out, negatively impacting the user experience.

[0009] In one optional embodiment, the water outlet device further includes a guide portion extending in a direction away from the rotating fit structure and flush with or beyond the projection edge of the mop board on the cleaning surface in the cleaning state. The guide portion is disposed adjacent to the water outlet and is adapted to carry water overflowing from the water outlet.

[0010] Beneficial effects:

[0011] By providing water outlets on the cleaning surface of the housing and a guide section extending away from the rotating fit structure and flush with or exceeding the projection edge of the mop board on the cleaning surface in the cleaning state, the water connection section can be connected to an external water source. This allows the guide section to direct the water from the outlets to a position flush with or exceeding the edge of the mop board after water is supplied to the cleaning surface. This achieves effective water flow, increases the water-passing area on the cleaning surface, and ensures that the mop board in areas not covered by the outlets can also be cleaned by the water guided by the guide section. This allows the mop board to be effectively cleaned, effectively avoids the existence of cleaning dead corners, and overcomes the defect that the outer edges of the mop and mop board are difficult to soak in water and cannot be effectively cleaned, thus affecting the user experience.

[0012] In one alternative embodiment, the guide portion is formed as a groove on the cleaning surface.

[0013] Beneficial effects:

[0014] The flow guide section has a trough-shaped structure, which facilitates water collection and flow guidance.

[0015] In one alternative embodiment, the bottom height of the guide section gradually decreases in the direction from the rotating connection to the edge of the mop board.

[0016] Beneficial effects:

[0017] With this design, the guide section can provide power through the height difference, guiding the water from the outlet from the higher rotating connection to the lower edge of the mop board, thereby allowing the water to flow through and wet the entire cleaning surface, achieving effective water flow and increasing the water-passing area on the cleaning surface.

[0018] In one alternative embodiment, the guide portion is arranged in the form of an annular groove and surrounds the outer periphery of the water outlet.

[0019] Beneficial effects:

[0020] The guide section is designed as an annular groove outside the water outlet. This allows the water flow from the water outlet to fall completely into the guide section, preventing water from bypassing the guide section and splashing directly onto the cleaning surface, thus improving the efficiency of water flow utilization.

[0021] In one alternative embodiment, the top end face of the guide channel wall is set lower than the water outlet hole.

[0022] Beneficial effects:

[0023] This design utilizes the height difference between the water outlet and the guide section to provide driving force for the water flow from the water outlet to the guide section.

[0024] In one optional embodiment, the flow guiding part further includes: an inner ring groove wall, connected to the bottom of the flow guiding part and surrounding the outer periphery of the water outlet, with its top end face lower than the water outlet, suitable for guiding the water flow from the water outlet to the bottom of the groove; and an outer ring groove wall, disposed opposite to the inner ring groove wall and surrounding the outer side of the inner ring groove wall.

[0025] Beneficial effects:

[0026] The inner and outer ring walls are set up around the outside of the boss structure. This allows the water flowing from the outlet hole into the guide section directly, preventing water from bypassing the guide section and spilling out from the cleaning surface, thus improving the utilization efficiency of the water flow.

[0027] In one optional embodiment, the inner annular groove wall is arc-shaped, which is suitable for guiding the water flow from the outlet hole to the bottom of the guide section.

[0028] Beneficial effects:

[0029] This design reduces the impact of water flow on the inner ring channel wall and improves the flow guiding efficiency of the inner ring channel wall.

[0030] In one optional embodiment, the water outlet device further includes: a plurality of scraper components protruding from the cleaning surface, wherein the upper ends of the plurality of scraper components are positioned above the water outlet holes.

[0031] Beneficial effects:

[0032] The scraper attachment allows you to scrape and brush the bottom of the mop board after cleaning, combing the bottom of the mop board so that water can penetrate more easily and improve the cleaning effect.

[0033] In one alternative embodiment, the height of the brush member closer to the rotating mating structure is less than the height of the brush member farther away from the rotating mating structure.

[0034] Beneficial effects:

[0035] The brush is positioned at a height that is far from the rotating structure, and this position is the end of the flow guide. This design effectively improves the soaking and brushing effect at the edge of the mop board, which is far from the water outlet, and can effectively clean the outer edges of the mop cloth and mop board.

[0036] In one alternative embodiment, the scraper is formed into a cylindrical shape, with the outer diameter of the upper end being smaller than the outer diameter of the lower end.

[0037] Beneficial effects:

[0038] This design facilitates processing and reduces the requirements for molding dies. It also avoids sharp parts on the circumference of the brush, which could cause scratches or abrasions to the structure being cleaned. In addition, the top-thin and bottom-coarse design results in a relatively large contact area between the brush and the cleaning surface, increasing the strength of the brush and its stability on the cleaning surface.

[0039] In one alternative embodiment, the top of the scraper is rounded and convex.

[0040] Beneficial effects:

[0041] This design, combined with the cylindrical shape of the scraper, allows the outer wall of the scraper to be curved or circular, further improving the safety of the structure and effectively preventing scratches or abrasions between the scraper and the structure to be cleaned.

[0042] In one alternative embodiment, the scraper is staggered on the outer annular groove wall located on both sides of the water outlet, along the direction of relative rotation between the mop board and the water outlet bracket.

[0043] Beneficial effects:

[0044] By setting the scraper components and the outer ring groove wall in a staggered arrangement, a double row of raised structures is formed on both sides of the water outlet. When the mop passes through the two rows of scraper components in sequence, the scraping positions of the two rows of scraper components are different, which increases the combing effect on the bottom of the mop board and enhances the scraping and cleaning effect on the mop board.

[0045] When the water outlet device includes a flow guide and the outer side of the flow guide is provided with an outer ring groove wall, the lower end of the scraper is formed as part of the outer ring groove wall, and the upper end is set higher than the water outlet hole.

[0046] Beneficial effects:

[0047] By integrating the scraper and the outer ring groove wall, the structure is simple and easy to implement, reducing the complexity of the structure, saving materials, and increasing the structural strength of both the scraper and the outer ring groove wall.

[0048] The water connection section includes: a water preparation chamber formed inside the housing, communicating with the water outlet, and having an opening on the side opposite to the cleaning surface, suitable for connecting to an external water source.

[0049] Beneficial effects:

[0050] By setting up a backup water chamber, it can serve as a water flow transfer and buffer structure, regulating the water pressure and flow rate of the outlet, and preventing the initial water pressure or flow rate of the external water source from exceeding the capacity of the outlet.

[0051] The cleaning tool also includes a locking part disposed on the outside of the housing, adapted to be detachably locked with the water supply structure of the cleaning tool.

[0052] Beneficial effects:

[0053] By incorporating a locking mechanism, the water outlet device can be detachably and washably connected to the external structure, facilitating maintenance and cleaning of the device's interior.

[0054] In one optional embodiment, the mop head further includes a cleaning cloth disposed at the bottom of the mop board; the mop board is shaped like an equilateral triangle, rectangle, or square, and the ends of each side of the mop board are rounded.

[0055] Beneficial effects:

[0056] The mop handle has rounded corners at the ends, which improves the user experience and prevents sharp parts from scratching the user or the mop bucket.

[0057] In one optional embodiment, the rotating connection portion is disposed at the center of the bottom side of the mop board and is coaxially arranged with the rotating engagement structure. The projection of the mop board, with the rotating connection portion as the center and the shortest distance from it to the edge of the mop board as the radius, onto the cleaning surface of the water outlet device completely covers the water outlet hole of the water outlet device.

[0058] Beneficial effects:

[0059] By setting the mop board to an equilateral triangle, rectangle, or square shape, and placing the rotating connection part at the center of the bottom side of the mop board and coaxial with the rotating engagement structure, this design can reduce the waste of mop board area, increase the proportion of the area that covers the water outlet during rotation, reduce the required size of the mop bucket, and lower costs.

[0060] In one optional embodiment, the top side of the water outlet bracket is provided with a receiving groove communicating with the water supply structure. The receiving groove is adapted to accommodate the water outlet device and is detachably connected to the water outlet device.

[0061] In one optional embodiment, the mop bucket further includes: a bucket body, on which a clean water trough protrudes from the bottom surface, the clean water trough having the water supply structure built in and the water outlet bracket connected to the top side; and a wastewater trough, disposed between the inner wall of the bucket body and the outer wall of the clean water trough, and separated from the clean water trough.

[0062] In one optional embodiment, the water supply structure includes: a water supply drive unit disposed within the clear water tank; and a vertical channel communicating with the receiving tank and the clear water tank, adapted to supply water to the receiving tank under the action of the water supply drive unit.

[0075] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0076] like Figure 1 - Figure 6This embodiment provides a cleaning tool, which includes: a mop 4, a mop bucket 5, and a water outlet device.

[0077] The mop 4 includes a handle 401 and a mop head. The mop head includes a mop plate 402, which is movably connected to the lower end of the handle 401. The mop plate 402 is also provided with a rotating connecting part 403. The diameter of the mop plate 402 varies from the rotating connecting part 403 to the edge of the mop plate 402. The specific shape of the mop plate 402 is not limited. Preferably, it can be a regular shape such as an equilateral triangle, rectangle or square, or it can be an irregular polygon or elliptical structure. In addition, when the rotating connecting part 403 is located in a non-central position, the mop plate can also be circular.

[0078] The mop bucket 5 has a built-in water supply structure and a water outlet bracket 502. Preferably, the water outlet bracket 502 is disc-shaped, and a rotating engagement structure 503 is provided on the top side of the water outlet bracket 502. Preferably, the rotating engagement structure 503 is located at the center of the water outlet bracket 502. The mop blade 402 is detachably and movably connected to the rotating engagement structure 503 through the rotating connection part 403, which is suitable for rotating relative to the water outlet bracket 502 with the rotating connection part 403 as the center under the action of external force. Specifically, both the rotating connection part 403 and the water outlet bracket 502 can be a protrusion and a groove. Preferably, the rotating connection part 403 is grooved to avoid the protrusion affecting the use of the cleaning component 4 and to ensure the user's experience.

[0079] The top side of the water outlet bracket 502 is also provided with a water outlet device, which includes: a housing 1 and at least one water outlet hole 2.

[0080] The housing 1 includes a cleaning surface 101 and a water-connecting part, which is connected to the water supply structure. The cleaning surface 101 is in a cleaning state where it moves relative to the mop plate 402. Further, the relative movement of the cleaning surface 101 with respect to the mop plate 402 is specifically a relative rotation. As a possible implementation, the relative movement can also be a reciprocating motion of both along the length of the cleaning surface 101 or in the radial direction of the water outlet bracket 502.

[0081] In this embodiment, the housing 1 is detachably mounted on the main structure of the water outlet device. Preferably, the housing 1 is a long rectangular box with rounded ends along its length. A cleaning surface 101 is provided on the top end face of the housing 1, and a water connection part is provided on the bottom. The water connection part connects to the water supply structure. The connection part can also be provided on the side of the housing 1 or other positions. The shape of the housing 1 is not limited, as long as it connects to the water supply structure and moves relative to the mop board 402. As a variable implementation, the housing 1 can be integrally formed with the main structure of the water outlet device, that is, the housing 1 serves as the outer shell of the water outlet device.

[0082] The water outlet 2 is connected to the water connection part and is located on the cleaning surface 101 near the rotating engagement structure 503, suitable for being completely covered by the projection of the mop board 402 on the cleaning surface 101 during the cleaning process. Since the mop board 402 will move relative to the cleaning surface 101 during the cleaning process, in this embodiment, being completely covered by the projection means maintaining the state of being covered by the projection during the relative movement.

[0083] By setting a rotating connection part 403 and a water outlet device, the mop board 402 and the water outlet bracket 502 equipped with the water outlet device can rotate relative to each other, and the water outlet hole 2 on the water outlet device is completely covered by the projection of the mop board 402 on the cleaning surface 101. Furthermore, during the cleaning process, the mop board 402 rotates relative to the water outlet bracket 502. During the rotation of the mop board 402, its projection on the cleaning surface 101 rotates accordingly, and can cover the water outlet hole 2 on the cleaning surface 101 throughout the process. This setting avoids the water outlet hole 2 from spraying out of the gaps that appear during the rotation of the non-circular mop board 402 to the inner wall or outside of the mop bucket 5 during the movement of the mop board 402. This effectively improves the user experience and overcomes the defect in the prior art that when the shape of the mop head is non-circular, the water from the spray nozzle will bypass the mop head and spray onto the inner wall of the mop bucket 5 and splash out of the mop bucket 5, affecting the user experience.

[0084] Preferably, the water outlet device further includes a guide section 3, which extends in a direction away from the rotating fit structure 503 and is flush with or extends beyond the projection edge of the mop board 402 on the cleaning surface 101 in the cleaning state. The guide section 3 is arranged adjacent to the water outlet 2 and is suitable for carrying the water overflowing from the water outlet 2.

[0085] By providing a water outlet 2 on the cleaning surface 101 of the housing 1, and providing a guide portion 3 extending in a direction away from the rotating mating structure 503 and flush with or exceeding the projection edge of the mop board 402 on the cleaning surface 101 in the cleaning state, the water connection portion can be connected to an external water source. In this way, after the water outlet 2 supplies water to the cleaning surface 101, the guide portion 3 can guide the water from the water outlet 2 to a position flush with or exceeding the edge of the mop board 402, thereby achieving effective water flow, increasing the water flow area on the cleaning surface 101, ensuring that the mop board 402 can be effectively cleaned, effectively avoiding the existence of cleaning dead corners, and avoiding the defects of the mop and the outer edge of the mop board being difficult to soak in water and thus unable to be effectively cleaned, which affects the user experience.

[0086] Preferably, the flow guide 3 is disposed on the housing 1 and is formed as a groove on the cleaning surface 101. The flow guide 3 has a groove-shaped structure, which facilitates water collection and flow guidance. As an alternative embodiment, the flow guide 3 may also be disposed on the top surface of the water outlet bracket 502 where the housing 1 is not disposed.

[0087] Preferably, the bottom height of the guide section 3 gradually decreases in the direction from the rotating connection 403 to the edge of the mop plate 402. This arrangement allows the guide section 3 to provide power through the height difference, guiding the water from the outlet 2 from the higher rotating connection 403 to the lower edge of the mop plate 402, thereby allowing the water to flow through and wet the entire cleaning surface 101, achieving effective water flow and increasing the water-passing area on the cleaning surface 101. Alternatively, the bottom of the guide section 3 can also be set at a uniform height.

[0088] Preferably, the guide section 3 is arranged in the form of an annular groove and surrounds the outer periphery of the water outlet 2. By setting the guide section 3 as an annular groove outside the water outlet 2, the water flow from the water outlet 2 can completely fall into the guide section 3, preventing water from splashing directly onto the cleaning surface 101 without passing through the guide groove, thus improving the utilization efficiency of the water flow. As an alternative implementation, the guide section 3 can also be arranged as a straight groove or a curved groove, and its quantity can be one, two, or more.

[0089] Preferably, the top end face of the channel wall of the guide section 3 is lower than the water outlet 2. Specifically, a boss structure can be provided on the cleaning surface 101. When the housing 1 is flat and the cleaning surface 101 is the top surface of the housing 1, the boss structure is higher than the cleaning surface 101, and the water outlet 2 is located on the boss structure. By setting the water outlet 2 on the boss structure, the top end face of the channel wall of the guide section 3 is lower than the water outlet 2. With this arrangement, the height difference between the water outlet 2 and the guide section 3 can be used to provide driving force for the water outlet 2 to flow into the guide section 3.

[0090] Preferably, the flow guide 3 further includes: an inner annular groove wall 301 and an outer annular groove wall 302.

[0091] The inner ring wall 301 is connected to the bottom of the guide section 3 and surrounds the outer periphery of the outlet hole 2. Its top end face is lower than the outlet hole 2, which is suitable for guiding the water flow from the outlet hole 2 to the bottom of the tank. The outer ring wall 302 is arranged opposite to the inner ring wall 301 and surrounds the outside of the inner ring wall 301. Preferably, the outer ring wall 302 and the inner ring wall 301 are evenly spaced, and the top corners of the outer ring wall 302 and the inner ring wall 301 are rounded. The inner ring wall 301 and the outer ring wall 302 are arranged around the outside of the boss structure, so that the water flow falling from the outlet hole 2 from the boss structure can fall completely into the guide section 3, avoiding water from splashing directly from the cleaning surface 101 without passing through the guide channel, thus improving the utilization efficiency of the water flow.

[0092] Preferably, the inner annular groove wall 301 is arc-shaped, suitable for guiding the water flow from the outlet hole 2 to the bottom of the guide section 3. More preferably, the inner annular groove wall 301 is convex arc-shaped. This design reduces the impact of the water flow on the inner annular groove wall 301 and improves the guiding efficiency of the inner annular groove wall 301.

[0093] The water outlet device also includes several scraper components 104, which protrude from the cleaning surface 101 and are arranged in a direction away from the rotating engagement structure 503. The upper ends of the scraper components 104 extend above the water outlet holes 2. This arrangement of the scraper components 104 allows for scraping the bottom surface of the mop board 402 on top of cleaning, improving the cleaning effect. In this embodiment, the spacing between adjacent scraper components 104 is evenly distributed. Preferably, the direction of relative movement between the cleaning surface 101 and the structure to be cleaned intersects with the arrangement direction of the scraper components 104; further, they are arranged perpendicularly.

[0094] Preferably, the height of the scraper 104 near the rotating engagement structure 503 is less than the height of the scraper 104 away from the rotating engagement structure 503. Setting the scraper 104 at a higher height away from the rotating engagement structure 503, and arranging this position as the end of the flow guide, effectively improves the water absorption and scraping effect at the edge of the mop board 402, which is farther from the water outlet 2, allowing for effective cleaning of the mop cloth and the outer edges of the mop board 402. More preferably, the height of the scraper 104 changes gradually. As a possible implementation, several scraper 104 can be arranged in a continuously undulating, flush configuration.

[0095] Preferably, the scraper 104 is cylindrical, with the outer diameter of the upper end being smaller than that of the lower end. This design avoids sharp edges on the circumference of the scraper 104, preventing scratches or snagging with the mop board 402. Furthermore, the tapered shape at the top and thicker shape at the bottom increases the contact area between the scraper and the cleaning surface 101, enhancing the strength of the scraper and its stability on the cleaning surface 101. Alternatively, the scraper 104 can also be tapered.

[0096] Preferably, the top of the scraper 104 is rounded and convex. This design, combined with the cylindrical shape of the scraper 104, allows the outer wall of the scraper 104 to be arc-shaped or circular, further improving the safety of the structure and effectively preventing scratches or abrasions between the scraper 104 and the structure to be cleaned.

[0097] In this embodiment, when the guide section 3 includes the outer ring groove wall 302, the lower end of the scraper 104 is formed as part of the outer ring groove wall 302, and the upper end is set higher than the water outlet hole 2. This makes the scraper 104 and the outer ring groove wall 302 integrally formed, which is simple and easy to implement, and can increase the structural strength of both the scraper 104 and the outer ring groove wall 302.

[0098] As an alternative implementation, along the direction of relative movement between the mop blade 402 and the cleaning tool, the scraper 104 is staggered with the outer annular groove walls 302 located on both sides of the water outlet 2. Preferably, the annular scraper 104 and the annular outer annular groove walls 302 can be arranged in a double-row structure with equal intervals. By setting the scraper 104 and the outer annular groove walls 302 in a staggered arrangement, a double-row protruding structure is formed on both sides of the water outlet 2, increasing the scraping and cleaning effect on the structure to be cleaned.

[0099] Preferably, the water connection section includes a water storage chamber 102, which is formed inside the housing 1, communicates with the water outlet 2, and is opened along the side facing away from the cleaning surface 101, suitable for connecting to an external water source. Specifically, the lower end of the housing 1 is open, and the internal space is the water storage chamber 102. As a variable implementation, the water outlet 2 can also be directly connected to the water supply structure. By providing the water storage chamber 102, it can serve as a water flow transfer structure and a buffer structure, regulating the water pressure and flow rate of the water outlet 2, and preventing the initial water pressure or flow rate of the external water source from exceeding the carrying capacity of the water outlet 2.

[0100] In addition, the water outlet device also includes a locking part 103, which is disposed on the outside of the housing 1 and is suitable for detachably locking with the water supply structure of the cleaning tool. Preferably, the locking part 103 is either a locking block or a locking groove. The other of the locking block or locking groove can be provided on the water supply structure to achieve the locking connection. By providing the locking part 103, the water outlet device can be detachably connected to the water supply structure, which facilitates maintenance and cleaning of the inside of the water outlet device. As an alternative implementation, the water outlet device and the water supply structure of the cleaning tool can also be connected by screws or magnetic attraction.

[0101] Preferably, the mop head also includes a cleaning cloth, which is disposed at the bottom of the mop board 402 and can contact the cleaning surface 101. Preferably, the mop board 402 is shaped like an equilateral triangle, rectangle, or square, which is simple and easy to manufacture, and the ends of each side of the mop board 402 are rounded. The rounded ends of the mop board 402 can improve the user experience and prevent sharp parts from scratching the user or the mop bucket 5 and other structures.

[0102] Preferably, the rotating connection part 403 is disposed at the center of the bottom side of the mop plate 402 and is coaxially disposed with the rotating fitting structure 503. The projection of the mop plate 402, with the rotating connection part 403 as the center and the shortest distance from it to the edge of the mop plate 402 as the radius, on the cleaning surface 101 of the water outlet device completely covers the water outlet hole 2 of the water outlet device.

[0103] By setting the mop plate 402 to be an equilateral triangle, rectangle, or square, and setting the rotating connection part 403 to be located at the center of the bottom side of the mop plate 402 and coaxial with the rotating engagement structure 503, this setting can reduce the area waste of the mop plate 402, increase the area ratio of the area covering the water outlet 2 during its rotation, reduce the required size of the mop bucket 5, and reduce costs.

[0104] In this embodiment, a receiving groove 504 communicating with the water supply structure is provided on the top side of the water outlet bracket 502. The receiving groove 504 is suitable for accommodating the water outlet device and is detachably connected to the water outlet device. In this embodiment, after the water outlet device is installed in the receiving groove 504, the cleaning surface 101 on the top side of the water outlet device is flush with the top surface of the water outlet bracket 502. By providing the receiving groove 504, the water outlet device can be detachably connected to the water supply structure, facilitating maintenance and cleaning of the inside of the water outlet device. As an alternative implementation, the receiving groove 504 may be omitted, and the water outlet bracket 502 may be integrally formed with the water outlet device.

[0105] Preferably, the mop bucket 5 further includes a bucket body and a wastewater tank 506. A clean water tank 505 is protruding from the inner bottom surface of the bucket body. The clean water tank 505 has a built-in water supply structure and a water outlet bracket 502 connected to its top side. The wastewater tank 506 is disposed between the inner wall of the bucket body and the outer wall of the clean water tank 505, and is separated from the clean water tank 505. In addition, the bucket body is also provided with a drainage structure that communicates with the wastewater tank 506.

[0106] This design separates the clean water tank 505 and the wastewater tank 506. By placing the water outlet bracket 502 on the top side of the clean water tank 505 and the wastewater tank 506 on the outside of the clean water tank 505, the cleaning water from the outlet can smoothly flow into the wastewater tank 506 along the outer wall of the clean water tank 505 or the mop head after cleaning. At the same time, it avoids the outlet being higher than the wastewater tank 506, preventing wastewater backflow and ensuring that the clean water tank 505 is not contaminated.

[0107] Preferably, the water supply structure includes a water supply drive and a vertical channel 501. The water supply drive is disposed in the clear water tank 505, and may be a water pump. The vertical channel 501 is connected to the receiving tank 504 and the clear water tank 505, and is adapted to supply water to the receiving tank 504 under the action of the water supply drive.

[0108] Work process:

[0109] The rotating connection part 403 of the mop plate 402 is installed on the rotating fitting structure 503 of the water outlet bracket 502 inside the mop tube. The user holds the rod 401 and drives the mop plate 402 to rotate relative to the water outlet bracket 502. In this embodiment, a rotating shaft and a spiral drive structure are provided inside the clean water tank 505. The user can drive the mop plate 402 to rotate relative to the water outlet bracket 502 by pressing the rod 401 up and down. As an alternative implementation, a small drive motor can also be provided inside the clean water tank or the rod 401.

[0110] Turn on the water supply drive unit to transmit the clean water in the clean water tank 505 through the vertical channel 501 and the water preparation chamber 102 to the water outlet, and spray it out from the blower onto the cleaning cloth and mop board 402.

[0111] The clean water is sprayed onto the cleaning cloth and mop board 402, while the other part flows onto the guide section 3 and flows away from the rotating mating structure 503, supplying the cleaning cloth and mop board 402 at the edge. The cleaning cloth and mop board 402 are completely wetted and cleaned. The wastewater flows along the cleaning cloth and mop board 402 and the outer wall of the clean water tank 505 into the wastewater tank 506, and is finally discharged through the drainage structure.

[0112] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
