When cleaning the cleaning cloth 420, the cleaning cloth 420 is placed in the cleaning area and abuts against the ribs 311, the cleaning cloth 420 is driven to rotate by the floor cleaning machine, at the moment, the cleaning liquid in the first cavity 210 is conveyed to the cleaning area under the action of the execution piece 130, and the ribs 311 scrape the cleaning cloth, so that the automatic cleaning of the cleaning cloth 420 is realized. The top and bottom referred to above correspond to the top and bottom in the drawings.

In the present invention, the barrel body 200 is hollow, and has an open top, the first cavity 210 and the second cavity 230 for storing the contaminated liquid are disposed in the barrel body 200, the second cavity 230 and the first cavity 210 are independent of each other, and the first cavity 210 and the second cavity 230 are independent of each other, which means that the second cavity 230 and the first cavity 210 are not communicated with each other, such that the cleaning liquid and the contaminated liquid can be separated. The plate-shaped main body 310 is located above the first cavity 210 and the second cavity 230, dirty liquid generated by the cleaning cloth 420 in the cleaning process can be collected into the second cavity 230 along the extending direction of the ribs 311, and dirty liquid generated by the cleaning cloth 420 in the spin-drying process can be collected into the second cavity 230 along the extending direction of the ribs 311, so that dirty liquid collection is achieved. 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.

In the present invention, as shown in fig. 6 to fig. 9, 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. A second inlet port 111 and a second outlet port 112 are provided at the bottom of the base housing 110 to facilitate inlet and outlet of liquid. Referring to fig. 4, 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. In order to prevent the dirty liquid from entering the accommodating cavity 113 through the second liquid outlet 112, a first valve 1111 is disposed at the second liquid inlet 111, a second valve 1121 is disposed at the second liquid outlet 112, the first valve 1111 allows the second liquid inlet 111 to be selectively communicated with the first cavity 210, and the second valve 1121 allows the second liquid outlet 112 to be selectively communicated with the cleaning region.

In consideration of the installation problem of the first valve body 1111 and the second valve body 1121, in the present invention, the first valve body 1111 and the second valve body 1121 are provided on the valve body mounting seat 160, and the valve body mounting seat 160 is provided in the accommodating cavity 113, so that the first valve body 1111 and the second valve body 1121 have the advantages of convenient installation and stable and reliable connection.

Further, the first valve body 1111 and the second valve body 1121 are one-way valves, and when the actuator 130 moves toward the driving member 120, a pressure difference between the receiving cavity 113 and the first cavity 210 causes the first valve body 1111 to be in a communication state. When the actuator 130 moves toward the bottom of the barrel 200, the second valve 1121 is in a communication state under the pressure of the liquid in the receiving cavity 113. In the present invention, when the first valve body 1111 is in the on state, the second valve body 1121 is in the off state; when the second valve body 1121 is in the on state, the first valve body 1111 is in the off state. The first valve body 1111 and the second valve body 1121 are made of soft elastic material, in an embodiment, the first valve body 1111 and the second valve body 1121 are duckbill valves, a duckbill portion of the first valve body 1111 is horizontally disposed toward the accommodating cavity 113, and a duckbill portion of the second valve body 1121 is vertically disposed toward the plate-shaped main body 310.

Having fully described the operation of the first valve body 1111 and the second valve body 1121, those skilled in the art will understand the following water supply principle:

when the actuator 130 moves toward the driving member 120 (when the actuator 130 moves upward), the air pressure in the cavity below the actuator 130 becomes lower, the first valve body 1111 of the second liquid inlet 111 is opened by the pressure difference between the first cavity 210 and the accommodating cavity 113, the second valve body 1121 of the second liquid outlet 112 is in a closed state, and the accommodating cavity 113 is in a liquid inlet state.

When the actuator 130 moves toward the bottom of the barrel 200 (when the actuator 130 moves downward), the air pressure in the cavity below the actuator 130 increases, the second valve 1121 is opened by the liquid pressure of the receiving cavity 113, the first valve 1111 is in a closed state, and at this time, the receiving cavity 113 is in a liquid outlet state for delivering liquid to the cleaning area.

In the present invention, please refer to fig. 3 and 10, the actuator 130 is abutted under the driving member 120 by the elastic element 140, and the elastic element 140 is configured to drive the actuator 130 to move toward the driving member 120 to achieve the resetting. The driving member 120 includes a rotating head 121 and a fitting 122, the rotating head 121 abuts against the fitting 122, the fitting 122 abuts against the actuating member 130, and the elastic element 140 is interposed between the fitting 122 and the actuating member 130. When the spin head 121 rotates in the first direction, the spin head 121 and the adaptor 122 rotate synchronously to make the actuator 130 deliver the cleaning liquid to the cleaning area; when the spin head 121 rotates in a second direction, which is opposite to the first direction, the spin head 121 and the adaptor 122 are disengaged to stop the actuator 130 from delivering the cleaning liquid to the cleaning area. 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 operation can be performed; when the spin head 121 rotates in the second direction, the cleaning area is in a drying mode, and drying operation can be performed. 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 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 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, the two adjacent cleaning heads 400 rotate in mirror symmetry about the middle of the axial center connecting line of the respective mounting shafts.

The driving force of the driving member 120 can be varied, and in one embodiment, the driving force of the driving member 120 is from a mopping machine (not shown) adapted to the washing member 300, and a power device (not shown) for driving the cleaning head 400 to rotate is provided on the mopping machine, and the power device of the mopping machine can be used for driving the rotating head 121 to rotate. In order to transmit the kinetic energy of the power device to the rotating head 121, in one aspect, the rotating head 121 is integrated with the cleaning head 400 of the floor cleaning machine, so that the power device can drive the rotating head 121 to rotate together when the cleaning head 400 is driven to rotate. In another mode, the rotating head 121 is disposed in the barrel 200 and exposed in the cleaning area, please continue to refer to fig. 13 and 14, the top of the rotating head 121 is hemispherical, the cleaning head 400 includes a mounting plate 410 disposed on the floor cleaning machine and a cleaning cloth 420 disposed on the mounting plate 410, a cavity 411 for accommodating the top hemisphere of the rotating head 121 is disposed in the center of the mounting plate 410, and 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, the hemispherical body at the top of the rotating head 121 is provided with a limiting block 1212, the cavity 411 is provided with a limiting groove 412 matched with the limiting block 1212, the relative rotation between the mounting disc 410 and the rotating head 121 can be prevented by the limiting block 1212 and the limiting groove 412, and therefore the rotating head 121 is ensured to rotate synchronously with the mounting disc 410. Therefore, when the driving force of the driving part 120 comes from the floor cleaning machine, a driving structure for driving the driving part 120 to rotate is not required to be arranged in the cleaning device, so that the number of parts is effectively reduced, and the production and use cost is 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 the rotational motion capability is disposed in the receiving cavity 113 for driving the rotator head 121 to rotate. The mechanism with rotational motion capability may be a motor, or may also be a gear box provided with a motor, and the mechanism with rotational motion capability includes, but is not limited to, the motor and the gear box, or may also be other mechanisms, which are not described in detail herein.

In order to enable the rotating head 121 and the adapter 122 to have two motion forms of synchronous rotation and disengagement, a first clamping structure 1211 is disposed at the bottom of the rotating head 121, and a second clamping structure 1222 matched with the first clamping structure 1211 is disposed at the top of the adapter 122. Referring to fig. 10 to 12, the first engaging structure 1211 includes at least one first tooth, the second engaging structure 1222 includes at least one second tooth, the first tooth is disposed around the bottom of the rotating head 121, and the second tooth is disposed around the top of the mating head 122. In the present invention, the first engaging structure 1211 includes a plurality of first teeth, each of which has a tooth height gradually increasing in the first direction, and the second engaging structure 1222 includes a plurality of second teeth, each of which has a tooth height gradually decreasing in the first direction, and the number of the first teeth is equal to the number of the second teeth. 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 rotary head 121 rotates in the second direction, the second tooth portion is disengaged from the shoulder groove, the tooth height end Q1 of the first tooth portion and the tooth height end Q2 of the second tooth portion cannot be brought into abutting engagement, and the adapter 122 cannot rotate following the rotary 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 order to convert the rotational motion of the fitting 122 into the linear reciprocating motion of the actuator 130, a first engagement portion 1221 is provided at the bottom of the fitting 122, and a second engagement portion 132 that abuts the first engagement portion 1221 is provided at the top of the actuator 130. In one embodiment, please refer to fig. 10, the first matching portion 1221 and the second matching portion 132 are coaxially disposed, the first matching portion 1221 has a convex end protruding toward the actuator 130, the convex end abuts against a top end surface E of the second matching portion 132, the top end surface E of the second matching portion 132 has a high end close to the rotator head 121 and a low end far away from the rotator head 121, wherein the actuator 130 moves upward in response to the convex end moving from the high end to the low end and moves downward in response to the convex end moving from the low end to the high end. In another embodiment, please refer to fig. 15 and 16, the first matching portion 1221 and the second matching portion 132 are eccentrically disposed, and the bottom end surface of the first matching portion 1221 abuts against the top end surface of the second matching portion 132, wherein one of the bottom end surface of the first matching portion 1221 and the top end surface of the second matching portion 132 is a horizontal plane, and the other one is an inclined plane, an arc plane, a combination surface of an arc plane and a horizontal plane, or a combination surface of an inclined plane and a horizontal plane. For convenience of understanding, defining the top end surface of the second fitting part 132 as a horizontal plane enables the second fitting part 132 to have different abutment positions due to different points on the bottom end surface of the first fitting part 1221 at the same height when the rotary head 121 rotates, thereby achieving the linear reciprocating motion of the actuator 130.

In this embodiment, the first liquid inlet 134a is disposed at the bottom of the actuator 130a, and includes the following two conditions: first, the first liquid inlet 134a is disposed on the bottom end surface of the actuator 130 a; second, the first inlet port 134a is disposed at the bottom of the sidewall of the actuator 130 a. The first liquid outlet 131a is disposed at the top of the actuator 130a, which also includes two cases: first, the first liquid outlet 131a is disposed on the top end surface of the actuator 130 a; second, the first liquid outlet 131a is disposed at the top of the sidewall of the actuator 130 a.

In this embodiment, when the actuator 130a linearly reciprocates in a vertical direction or in an inclined direction having a motion component in the vertical direction in response to the rotational motion of the driving member 120a, the actuator 130a has a first position away from the bottom of the barrel body 200a and a second position close to the bottom of the barrel body 200a, and the driving member 120a drives the actuator 130a to linearly reciprocate between the first position and the second position so that the cleaning liquid in the accommodating chamber 113a enters the liquid storage chamber Ma through the first inlet port 134a and is delivered to the cleaning region of the cleaning member 300a through the first outlet port 131 a.

In the course of executing 130a downstream, the cleaning solution body below executing 130a can produce and prevent the descending resistance of executing 130a, and this resistance can act on the cleaning liquid in stock solution chamber Ma through first inlet 134a, orders about the cleaning liquid in stock solution chamber Ma and flows to the washing district through first liquid outlet 131a, and under this condition, stock solution chamber Ma goes out liquid while admitting liquid, has the effectual advantage of confession liquid. In the process of upward movement of the actuator 130a, since the first liquid inlet 134a is located at the bottom of the actuator 130a, the cleaning liquid in the liquid storage cavity Ma is not affected by the cleaning liquid above the actuator 130a, and the cleaning liquid in the liquid storage cavity Ma cannot be conveyed to the cleaning area through the first liquid outlet, at this time, the liquid in the liquid storage cavity Ma is only fed into the liquid storage cavity Ma and does not flow out of the liquid storage cavity Ma.

In this embodiment, a recessed area is formed by recessing an area of the bottom of the first cavity 210a facing the actuator 130a, the recessed area is used for collecting the cleaning liquid at the bottom of the first cavity 210a, and an orthographic projection of the first liquid inlet 134a on the bottom of the first cavity 210a is located in the recessed area, so that a downward movement stroke of the first liquid inlet 134a is lengthened, thereby facilitating conveying the cleaning liquid at the bottom of the first cavity 210a to the cleaning area.

Further, the bottom end surface of the actuator 130a is further provided with a sealing member 135a, the sealing member 135a is annularly arranged on the periphery of the first liquid inlet 134a, and the recessed area is provided with an annular convex rib 220a matched with the sealing member 135 a. When the executing member 130a moves to the lower limit position, the sealing member 135a abuts against the annular rib 220a, so that the pressure in the liquid storage cavity Ma is ensured, and the dirty liquid generated during cleaning by the cleaning cloth can be prevented from flowing back into the liquid storage cavity Ma through the first liquid outlet 131 a.
