Referring to fig. 1 to 6, the present invention provides a cleaning device, including: a tub 200 storing clean water; a cleaning member 300, the cleaning member 300 being placed in the tub 200 and having a cleaning region; a base shell 110 disposed in the tub 200, the base shell 110 being hollow to form an accommodating chamber 113; a driving member 120 rotatably disposed on the base housing 110; the executing part 130, the executing part 130 is arranged in the accommodating cavity 113 and is matched with the driving part 120; when the driving member 120 is driven to rotate along the first direction, the driving member 120 drives the actuating member 130 to perform a linear reciprocating motion along a direction parallel to a plane where the first direction is located, so as to transport the clean water in the barrel 200 to the cleaning region through the accommodating cavity 113.

Through the above manner, in the present invention, the driving member 120 and the executing member 130 move relative to the base shell 110, so that the pressure inside the accommodating cavity 113 can be changed, and the clean water inside the barrel body 200 can be conveyed to the cleaning region of the cleaning member 300, and the present invention has the advantages of simple structure and good water supply effect.

Referring to fig. 7 and 8, the bottom of the floor cleaning machine is rotatably provided with a cleaning head 400, the cleaning head 400 comprises a mounting plate 410 arranged on the floor cleaning machine and a cleaning cloth 420 arranged on the mounting plate 410, and the cleaning cloth 420 is used for cleaning the surface to be cleaned. After the floor scrubbing machine performs the floor scrubbing task, the cleaning cloth 420 is cleaned by the cleaning member 300. Referring to fig. 9 and 10, the cleaning element 300 includes a plate-shaped main body 310 and a supporting portion 320 disposed on a bottom surface of the plate-shaped main body 310, the supporting portion 320 is used for supporting the plate-shaped main body 310, a plurality of ribs 311 are disposed on a top surface of the plate-shaped main body 310, and an area where the ribs 311 are located is a cleaning area of the cleaning element 300. When cleaning the cleaning cloth 420, the cleaning cloth 420 is placed in the cleaning area and abutted to the ribs 311, the floor cleaning machine drives the cleaning cloth 420 to rotate, at the moment, the clean water in the barrel body 200 is conveyed to the cleaning area under the action of the driving part 120 and the executing part 130, and the ribs 311 scrape the cleaning cloth, so that the cleaning cloth 420 is cleaned. The top and bottom referred to above correspond to the top and bottom in the drawings.

In the present invention, the tub 200 is hollow and has an open top, a first cavity 210 for storing clean water and a second cavity 230 for storing dirty liquid are disposed in the tub 200, the base shell 110 is disposed in the first cavity 210 and located below the plate-shaped main body 310, the second cavity 230 and the first cavity 210 are independent from each other, and the first cavity 210 and the second cavity 230 are independent from each other, i.e., the second cavity 230 and the first cavity 210 are not communicated with each other, such that clean water and dirty liquid can be separated. The plate-shaped main body 310 is located above the first cavity 210 and the second cavity 230, and the dirty liquid generated by the cleaning cloth 420 in the cleaning process can be gathered into the second cavity 230 along the extending direction of the ribs 311, so that the dirty liquid can be collected. The second cavities 230 may be distributed at various positions, and the second cavities 230 may be disposed at the periphery of the first cavity 210, or at the top of the first cavity 210, or at the bottom of the first cavity 210. Preferably, the second cavity 230 is annularly disposed on the periphery of the first cavity 210, and the edge of the plate-shaped main body 310 extends to the upper side of the second cavity 230, so that the contaminated liquid can fall into the second cavity 230 after flowing to the edge of the plate-shaped main body 310, and the liquid container has the advantages of simple structure and convenience in use.

Further, a second liquid inlet 111 and a second liquid outlet 112 are disposed on the base shell 110 and are communicated with the accommodating cavity 113, the second liquid inlet 111 is used for liquid inlet, and the second liquid outlet 112 is used for liquid outlet. Considering that the driving member 120 affects the flowing trend of the water flow during the rotation process, in order to ensure the stability and reliability of the liquid supply, the second liquid inlet 111 and the second liquid outlet 112 are disposed away from the driving member 120, and the second liquid inlet 111 is disposed at the bottom of the base shell 110, so that the clean water in the first cavity 210 can enter the accommodating cavity 113. Referring to fig. 9, a water outlet 312 is disposed on the plate-shaped main body 310, and the second liquid outlet 112 is communicated with the water outlet 312, so that the clean water entering the accommodating cavity 113 through the second liquid inlet 111 can flow to the cleaning area through the second liquid outlet 112. In the present invention, the cavity wall of the accommodating cavity 113 defines a translation path of the actuator 130, the actuator 130 has a first position close to the second inlet 111 and the second outlet 112 and a second position far from the second inlet 111 and the second outlet 112, and the actuator 130 linearly reciprocates between the first position and the second position.

In order to prevent the dirty liquid from entering the accommodating cavity 113 through the second liquid outlet 112 and enable the second liquid outlet 112 to have a better water supply effect, please refer to the drawings, a second valve 1121 is disposed at the second liquid outlet 112, and a first valve 1111 is disposed at the second liquid inlet 111. The first valve body 1111 selectively communicates the second liquid inlet 111 with the first cavity 210, and the second valve body 1121 selectively communicates the second liquid outlet 112 with the cleaning region. Specifically, the first valve body 1111 and the second valve body 1121 are one-way valves, and the operating states of the first valve body 1111 and the second valve body 1121 are opposite.

Having described the relationship among the second liquid inlet port 111, the second liquid outlet port 112, the first valve body 1111 and the second valve body 1121 sufficiently, those skilled in the art will understand the following working processes:

when the actuator 130 moves in a direction away from the second liquid inlet 111 and the second liquid outlet 112, the pressure of the cavity on the side of the second liquid inlet 111 and the second liquid outlet 112 decreases, the first valve 1111 is conducted, the second valve 1121 is in a closed state, the clean water in the first cavity 210 enters the accommodating cavity 113, and at this time, the accommodating cavity 113 is in a liquid inlet state;

when the actuator 130 moves toward the second liquid inlet 111 and the second liquid outlet 112, the pressure of the cavity on the side of the second liquid inlet 111 and the second liquid outlet 112 increases, the second valve 1121 is conducted, the first valve 1111 is closed, the clean water in the accommodating cavity 113 is delivered to the cleaning region, and at this time, the accommodating cavity 113 is in a liquid supply state.

The driving force of the driving member 120 can be derived from various sources, in one embodiment, the driving force of the driving member 120 is derived from a floor cleaning machine adapted to the cleaning member 300, and the driving member 120 is driven to rotate by a power assembly (not shown) on the floor cleaning machine, so that a driving structure for driving the driving member 120 to rotate is not required to be arranged inside the cleaning device, the number of parts is effectively reduced, and the production and use costs are reduced.

In another embodiment, the driving force of the driving member 120 is derived from a mechanism (not shown) having a rotational motion capability and disposed in the barrel 200, and the mechanism having a rotational motion capability may be a motor or a gear box having a motor. The mechanism with rotational motion capability includes, but is not limited to, the motor and the gear box, and may be other mechanisms, which are not described in detail herein.

In the present invention, when the driving force of the driving element 120 is from a floor cleaning machine adapted to the cleaning element 300, as shown in fig. 3 and 5, the driving element 120 includes a rotating head 121 and a main body 123, the main body 123 is at least partially located in the accommodating cavity 113 to cooperate with the actuating element 130, and when the rotating head 121 is driven to rotate along the first direction, the main body 123 rotates synchronously with the rotating head 121. The spin head 121 is disposed as follows: in the first mode, the rotating head 121 is integrated on the cleaning head 400 of the floor-cleaning machine, so that the power assembly of the floor-cleaning machine can drive the rotating head 121 to rotate together when driving the cleaning head 400 to rotate, and in the above arrangement mode, the part of the main body 123 extends to the outside of the accommodating cavity 113 and is exposed in the cleaning area for being butted with the rotating head 121. In the second mode, the spin head 121 is disposed in the barrel 200 and exposed in the cleaning region, and in the above mode, the spin head 121 may be rotatably disposed on the plate-shaped body 310 or rotatably disposed on the top of the base shell 110. Please refer to fig. 11 to 13, the top of the rotating head 121 is hemispherical, a cavity 411 for accommodating the hemispherical body at the top of the rotating head 121 is disposed in the center of the mounting disc 410, the cavity 411 is also hemispherical, in order to ensure that the mounting disc 410 can drive the rotating head 121 to rotate together when rotating, a limiting block 1212 is disposed on the hemispherical body at the top of the rotating head 121, a limiting groove 412 engaged with the limiting block 1212 is disposed in the cavity 411, the limiting block 1212 and the limiting groove 412 can prevent the relative rotation between the mounting disc 410 and the rotating head 121, thereby ensuring that the rotating head 121 rotates synchronously with the mounting disc 410.

Consider that after the wipe 420 is cleaned, the wipe 420 has a water stain and cannot be used directly. In the present invention, the driving member 120 further includes a fitting head 122, the fitting head 122 is fixedly disposed on the top of the main body 123, specifically, the fitting head 122 may be fixedly disposed on the top of the main body 123 through a bolt, a welding, a clamping, or the like, or may be integrally formed with the main body 123. In this way, when the rotating head 121 rotates along the first direction, the rotating head 121 can drive the main body 123 to rotate through the adaptor 122, so as to supply water to the cleaning area; when the spin head 121 rotates along the second direction, the spin head 121 cannot drive the main body 123 to rotate through the adapter 122, and at this time, water supply to the cleaning area cannot be achieved.

For convenience of illustration, the rotating head 121 is disposed in the barrel 200 and exposed in the cleaning region, in the above case, the adapter 122 abuts against the lower side of the rotating head 121, when the rotating head 121 rotates along the first direction, the rotating head 121 and the adapter 122 rotate synchronously to drive the main body 123 to rotate, and at this time, the actuator 130 supplies water to the cleaning region. When the spin head 121 rotates in the second direction, the spin head 121 and the coupling head 122 are disengaged to stop the movement of the body part 123, and at this time, the actuator 130 stops supplying water to the cleaning region. For a floor scrubber provided with only a single cleaning head 400, the first and second directions referred to above are different rotational directions of the floor scrubber cleaning head 400, the second direction being counter clockwise when the first direction is clockwise and clockwise when the first direction is counter clockwise. When the spin head 121 rotates along the first direction, the cleaning area is in a cleaning mode, and cleaning of the cleaning cloth can be performed; when the rotating head 121 rotates along the second direction, the cleaning area is in a drying mode, so that the drying operation of the rag can be performed, and the cleaning device has the advantage of convenience in use. For a floor mopping machine with a plurality of cleaning heads, the plurality of cleaning heads 400 are arranged at the bottom of the floor mopping machine in parallel, the rotation directions of the plurality of cleaning heads 400 may be the same or different, taking two cleaning heads 400 as an example, when the rotation directions of the two cleaning heads 400 are the same, the two cleaning heads 400 rotate simultaneously in the clockwise direction or simultaneously in the counterclockwise direction; when the rotation directions of the two cleaning heads 400 are not identical and when the spin head 121 rotates in the first direction (in this case, the first direction does not refer to a fixed direction), the first cleaning head 400 rotates in the clockwise direction and the second cleaning head 400 rotates in the counterclockwise direction, and when the rotation directions of the two cleaning heads 400 are not identical and when the spin head 121 rotates in the second direction (in this case, the second direction does not refer to a fixed direction), the first cleaning head 400 rotates in the counterclockwise direction and the second cleaning head 400 rotates in the clockwise direction, that is, two adjacent cleaning heads 400 rotate in mirror symmetry about the middle of the axial center connecting line of the respective mounting shafts.

Further, a first clamping structure 1211 is disposed at a bottom of the rotating head 121, and a second clamping structure 1222 engaged with the first clamping structure 1211 is disposed at a top of the adapter 122. The first latch structure 1211 includes at least one first tooth, and the second latch structure 1222 includes at least one second tooth. In the present invention, the number of the first tooth portions is equal to the number of the second tooth portions; the first clamping structure 1211 includes a plurality of first teeth annularly disposed at the bottom of the rotating head 121, and a tooth height of each first tooth gradually increases in a first direction; the second engaging structure 1222 includes a plurality of second teeth, the plurality of second teeth are disposed around the top of the mating connector 122, and a tooth height of each second tooth is gradually reduced in the first direction. Each of the first tooth portions has two end portions in the rotation direction of the rotary head 121, which are defined as a tooth lower end P1 and a tooth upper end Q1, and the tooth height of the tooth upper end Q1 is greater than the tooth height of the tooth lower end P1. A height difference exists between the tooth low end P1 and the tooth high end Q1 of two adjacent first tooth parts, so that a shoulder groove exists between the two adjacent first tooth parts. Similarly, each of the second tooth portions has two end portions in the rotation direction of the rotary head 121, which are defined as a tooth low end P2 and a tooth high end Q2, and the tooth height of the tooth high end Q2 is greater than the tooth height of the tooth low end P2. When the spin head 121 rotates in the first direction, the second tooth portion is engaged with the shoulder groove, and at this time, the tooth height end Q2 of the second tooth portion comes into contact with the tooth height end Q1 of the first tooth portion, so that the coupling head 122 rotates in synchronization with the spin head 121. When the rotator head 121 rotates in the second direction, the second tooth portion is disengaged from the shoulder groove, and the tooth height end Q1 of the first tooth portion and the tooth height end Q2 of the second tooth portion can no longer form an abutting engagement, in which case the friction force between the adapter 122 and the rotator head 121 is smaller than the rotational power of the rotator head 121, the adapter 122 cannot rotate along with the rotator head 121, and the adapter 122 is disengaged from the rotator head 121. It can be seen that the first and second latch structures 1211, 1222 are engaged only when the rotator head 121 is rotated in the first direction, so that the actuator 130 supplies water to the cleaning region; when the rotator head 121 rotates in the second direction, the first latch structure 1211 and the second latch structure 1222 are disengaged, so that the actuator 130 stops supplying water to the cleaning region.

In the present invention, the driving member 120 and the actuating member 130 are engaged with each other as described below, in an embodiment, the driving member 120 and the actuating member 130 are abutted with each other, as shown in fig. 3 and 4, an arc-shaped working surface H is disposed on the main body 123 in the circumferential direction, the actuating member 130 is abutted with the arc-shaped working surface H through an elastic element 140, the elastic element 140 is disposed on a side of the actuating member 130 away from the driving member 120, wherein the elastic element 140 is configured to urge the actuating member 130 to return, and the elastic element 140 is preferably a spring. The arcuate working surface H of the body portion 123 is an elliptical cylindrical surface or a cam surface, thereby enabling the actuator 130 to have different strokes when the body portion 123 rotates. In this embodiment, the base housing 110, the driving member 120, the actuator 130 and the elastic member 140 form a liquid supply assembly 100, and the liquid supply assembly 100 is used for delivering the clean water in the first cavity 210 to the cleaning region of the cleaning member 300.

In another embodiment, please refer to fig. 5 and fig. 6, the driving member 120 is connected to the actuating member 130 through a connecting rod 141, a first end of the connecting rod 141 is pivotally connected to the driving member 120, and an opposite second end is pivotally connected to the actuating member 130. The driving member 120 has a rotation axis L, a pivot shaft F is provided between the first end of the connecting rod 141 and the driving member 120, and the pivot shaft F and the rotation axis L are parallel to each other, thereby enabling the linear reciprocating motion of the actuator 130. In this embodiment, the base housing 110, the driving member 120, the actuator 130 and the connecting rod 141 form a liquid supply assembly 100, and the liquid supply assembly 100 is used for delivering the clean water in the first chamber 210 to the cleaning region of the cleaning member 300.

The above is only one embodiment of the present invention, and any other modifications based on the concept of the present invention are considered as the protection scope of the present invention.
