Through the manner, the liquid in the barrel body 200 is conveyed to the cleaning area through the relative movement between the driving part 120 and the executing part 130, and the cleaning device has the advantages of simple structure and convenience in liquid supply.

Referring to fig. 8 and 9, a cleaning head 400 is rotatably arranged at the bottom of the floor cleaning machine, the cleaning head 400 comprises a mounting disc 410 arranged on the floor cleaning machine and a cleaning cloth 420 arranged on the mounting disc 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 cloth 420 is washed by the washing member 300 of the cleaning device. Referring to fig. 5, the cleaning member 300 includes a plate-shaped main body 310 and a supporting portion 320 disposed on a bottom end 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 the top end surface of the plate-shaped main body 310, an area where the ribs 311 are located is a cleaning area of the cleaning member 300, a water outlet 312 corresponding to the first liquid outlet 131 is disposed on the plate-shaped main body 310, and the first liquid outlet 131 is communicated with the cleaning area through the water outlet 312. When cleaning the cloth 420, the cleaning liquid in the tub 200 enters the liquid storage cavity M through the first liquid inlet 134 in response to the relative movement between the driving member 120 and the actuating member 130 and is delivered to the cleaning region through the first liquid outlet 131, the cloth 420 is placed in the cleaning region and abuts against the ribs 311, and the ribs 311 scrape the cloth during the rotation of the cloth 420, so that the cleaning operation of the cloth 420 is realized. The top and bottom referred to above correspond to the top and bottom in the drawings.

In the present invention, as shown in fig. 1 to 4, the tub 200 is hollow, and has an open top, the tub 200 is provided with a first cavity 210 for storing a cleaning liquid and a second cavity 230 for storing a dirty liquid, the second cavity 230 and the first cavity 210 are independent from each other, and the second cavity 230 and the first cavity 210 are independent from each other, i.e., the second cavity 230 and the first cavity 210 are not communicated with each other, such that the cleaning liquid and the dirty liquid can be separated from each other. The actuator 130 is disposed in the first chamber 210 to enable the cleaning liquid in the first chamber 210 to be delivered to the cleaning region through the first liquid outlet 131.

Further, the plate-shaped body 310 is positioned above the first and second cavities 210 and 230. During the cleaning process of the cleaning cloth 420, the cleaning liquid in the first cavity 210 enters the liquid storage cavity M through the first liquid inlet 134 and is delivered to the cleaning region through the first liquid outlet 131 in response to the relative movement between the driving member 120 and the actuating member 130, and the dirty liquid generated by the cleaning cloth 420 is merged into the second cavity 230 along the extending direction of the ribs 311. During the spin-drying process of the cloth 420, the dirty liquid scraped by the ribs 311 flows into the second cavity 230 along the extending direction of the ribs 311, so as to collect the dirty liquid. 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.

The first embodiment is as follows: referring to fig. 1 to 17, in the present embodiment, the driving element 120 and the actuating element 130 move cooperatively, and the actuating element 130 makes a straight reciprocating motion in a vertical direction in the first cavity 210 in response to the movement of the driving element 120, where the vertical direction can be understood as an up-down direction. The first liquid inlet 134 is disposed at the bottom of the actuator 130, and the first liquid outlet 131 is disposed at the top of the actuator 130. The first liquid inlet 134 is disposed at the bottom of the actuator 130, and includes two conditions: first, the first liquid inlet 134 is disposed on the bottom end surface of the actuator 130; second, the first inlet port 134 is disposed at the bottom of the sidewall of the actuator 130. Similarly, the first liquid outlet 131 is disposed at the top of the actuator 130, which includes two conditions: first, the first liquid outlet 131 is disposed on the top end surface of the actuator 130; second, the first liquid outlet 131 is disposed at the top of the sidewall of the actuator 130.

Specifically, the actuator 130 has a first position far away from the bottom of the barrel 200 and a second position close to the bottom of the barrel 200, and the driving member 120 drives the actuator 130 to reciprocate linearly between the first position and the second position so that the liquid in the liquid storage cavity 134 is pressed to flow out of the first liquid outlet 131. When executive 130 moves down, the cleaning fluid body below executive 130 can produce and prevent the descending resistance of executive 130, and this resistance can act on the cleaning fluid in stock solution chamber M through first inlet 134, orders about the cleaning fluid in stock solution chamber M and flows to the washing district through first liquid outlet 131, and under this condition, stock solution chamber M goes out liquid on the limit of feed liquid, has the effectual advantage of confession liquid. When the actuator 130 moves upward, since the first liquid inlet 134 is located at the bottom of the actuator 130, the cleaning liquid in the liquid storage chamber is not affected by the cleaning liquid above the actuator 130, and the cleaning liquid in the liquid storage chamber M cannot be conveyed to the cleaning region through the first liquid outlet without external force, at this time, the liquid storage chamber only has liquid inlet and does not have liquid outlet.

The actuator 130 is in floating contact with the lower part of the driver 120 through the elastic element 140, so that the actuator 130 has a floating displacement in the vertical direction. The position of the elastic element 140 can be selected, and in the first type, the elastic element 140 is arranged between the actuating element 130 and the driving element 120, and the elastic element 140 has continuous contraction pulling force to enable the actuating element 130 to reset upwards; second, the elastic element 140 is disposed between the actuator 130 and the bottom of the barrel 200 for driving the actuator 130 to return upward. In fig. 4, the elastic member 140 is disposed between the actuator 130 and the bottom of the tub 200, and the elastic member 140 is preferably a compression spring.

The driving member 120 can be provided in various forms, and in one embodiment, the driving member 120 includes a rotating head 121 and a fitting 122 located below the rotating head 121, as shown in fig. 4, 7 and 12, the rotating head 121 abuts against the fitting 122, and the fitting 122 abuts against the actuating member 130. When the rotating head 121 rotates along the first direction, the rotating head 121 and the adaptor 122 rotate synchronously to make the executing member 130 do linear reciprocating motion between the first position and the second position so as to realize water supply to the cleaning area; when the rotator 121 rotates in the second direction, the rotator 121 and the adaptor 122 are disengaged to stop the movement of the actuator 130 and thus stop the water supply 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 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.

When the drive member 120 is in the form of a rotating head 121 and adaptor head 122 arrangement, the driving force of the drive member 120 may come from a floor scrubber fitted with the cleaning member 300. The power device (not shown) for driving the cleaning head 400 to rotate is disposed on the floor cleaning machine, and the rotating head 121 can be driven to rotate by the power device of the floor cleaning machine. 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 region, as shown in fig. 8, 9 and 13, the top of the rotating head 121 is hemispherical, a cavity 411 for receiving the top hemisphere of the rotating head 121 is disposed at 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.

When the driving member 120 is in the form of the rotating head 121 and the adapter 122, the driving force of the driving member 120 may also come from a mechanism (not shown) having a rotating motion capability and disposed in the barrel 200, the mechanism having the rotating motion capability is used to drive the rotating head 121 to rotate, the mechanism having the rotating motion capability may be a motor, or may be a gear box having a motor, and the mechanism having the rotating motion capability includes, but is not limited to, the motor and the gear box, or may be other mechanisms, which are not described in detail herein.

The driving member 120 can be disposed in various manners, and in another embodiment, the driving member 120 is a mechanism (not shown) disposed in the first cavity 210 and having a linear reciprocating capability, and the actuating member 130 performs a reciprocating motion in a vertical direction under the action of the mechanism having the linear reciprocating capability. In this case, the driving member 120 may be a cylinder, a push-pull electromagnet, an electric push rod, or the like.

In order to enable the rotating head 121 and the adapter 122 to have two moving configurations of synchronous rotation and disengaging, please refer to fig. 12 to 14, a first engaging structure 1211 is disposed at the bottom of the rotating head 121, and a second engaging structure 1222 engaged with the first engaging structure 1211 is disposed at the top of the adapter 122. The first latch structure 1211 includes at least one first tooth portion, and the second latch structure 1222 includes at least one second tooth portion, the first tooth portion is disposed at the bottom of the rotating head 121, and the second tooth portion is disposed at the top of the mating head 122. In the present invention, the first clamping structure 1211 includes a plurality of first teeth, all the first teeth are annularly disposed at the bottom of the rotating head 121, a tooth height of each first tooth is gradually increased in the first direction, the second clamping structure 1222 includes a plurality of second teeth, all the second teeth are annularly disposed at the top of the fitting head 122, a tooth height of each second tooth is gradually decreased 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 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. Therefore, the first and second latch structures 1211 and 1222 are engaged with each other only when the rotator head 121 rotates 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 horizontal rotation of the adaptor 122 into the linear reciprocating motion of the actuator 130 in the vertical direction, please refer to fig. 11, 12 and 14, a first matching portion 1221 is disposed at the bottom of the adaptor 122, and a second matching portion 132 abutting against the first matching portion 1221 is disposed at the top of the actuator 130. In one aspect, the first mating portion 1221 and the second mating portion 132 are coaxially disposed, the first mating portion 1221 has a convex end protruding toward the actuator 130, the convex end abuts against a top end surface E of the second mating portion 132, the top end surface E of the second mating 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 aspect, 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-shaped plane, a combination surface of an arc-shaped plane and a horizontal plane, or a combination surface of an inclined plane and a horizontal plane. For convenience of understanding, the top end surface of the second fitting part 132 is defined as a horizontal plane, and when the rotating head 121 rotates, since various points on the bottom end surface of the first fitting part 1221 are not at the same height, the second fitting part 132 can have different abutment positions in the vertical direction, thereby achieving the linear reciprocating motion of the actuator 130 in the vertical direction.

Further, as shown in fig. 4, a recessed area is formed by recessing an area of the bottom of the first cavity 210 facing the actuator 130, the recessed area is used for collecting the cleaning liquid at the bottom of the first cavity 210, and an orthographic projection of the first liquid inlet 134 on the bottom of the first cavity 210 is located in the recessed area, so that a downward movement stroke of the first liquid inlet 134 is lengthened, thereby facilitating conveying the cleaning liquid at the bottom of the first cavity 210 to the cleaning area. In the testing process, under the condition that the cavity bottom of the first cavity 210 is not provided with the depressed area, when the depth of the cleaning liquid in the first cavity 210 is 20mm, the cleaning liquid in the first cavity 210 can not supply liquid to the cleaning area any more; under the condition that the concave area is arranged at the bottom of the first cavity 210, when the depth of the cleaning liquid in the first cavity 210 is 20mm, the cleaning liquid can be continuously supplied to the cleaning area, so that the cleaning liquid in the first cavity 210 can be fully utilized, and the water supply effect is good.

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

In the present invention, the cleaning apparatus further includes a guiding column 150 and a base shell 110 disposed in the first cavity 210, as shown in fig. 4, fig. 7 and fig. 17, the base shell 110 has an opening at the bottom and an accommodating cavity 113 formed inside, the actuator 130, the guiding column 150 and the elastic element 140 are accommodated in the accommodating cavity 113, the base shell 110 is further provided with a second liquid inlet 111 and a second liquid outlet 112 communicated with the accommodating cavity 113, the second liquid inlet 111 is used for entering the cleaning liquid, and the second liquid outlet 112 is used for flowing out the cleaning liquid.

The rotating head 121 of the driving element 120 is exposed in the cleaning area, the adapter 122 of the driving element 120 is located in the accommodating cavity 113, the top of the guiding column 150 abuts against the rotating head 121, the guiding column 150 penetrates through the adapter 122 in the up-down direction, and the cross section of the matching part of the guiding column 150 and the adapter 122 is circular. In order to avoid relative rotation between the actuator 130 and the guide post 150, the cross section of the matching part of the guide post 150 and the actuator 130 is rectangular or square, and the through hole 133 is a square hole matched with the guide post 150. In the present invention, the base housing 110, the driving member 120, the actuating member 130, the elastic member 140 and the guiding post 150 form a liquid supply assembly 100, and the liquid supply assembly 100 is used for supplying cleaning liquid to the cleaning area of the cleaning member 300 for cleaning by the cleaning cloth 420.

Example two: in the present embodiment, referring to fig. 18 to 21, the actuating element 130a is fixed relative to the driving element 120a, the actuating element 130a is fixed in the first cavity 210a, and the liquid storage cavity Ma of the actuating element 130a is forced to change the pressure of the cleaning liquid in the liquid storage cavity Ma in response to the movement of the driving element 120a, so as to transport the cleaning liquid in the first cavity 210 to the cleaning area. The first liquid inlet 134a is disposed on a sidewall of the actuator 130a and faces the driving member 120a, and the first liquid outlet 131a is connected to the water outlet 312a of the plate-shaped main body 310 a. The driving member 120a is block-shaped or plate-shaped, and the driving member 120a and the actuating member 130a are located on the same extension line. The driving force of the driving member 120a comes from a mechanism 500a with linear reciprocating capability, and the mechanism 500a is arranged outside the liquid storage cavity Ma and is used for driving the driving member 120a to do linear reciprocating motion. The initial position of the driving member 120a is located outside the liquid storage cavity Ma, and the driving member 120a moves from the initial position toward the first liquid inlet 134a or resets from the moving position to the initial position under the action of the mechanism 500 a. The driving member 120a may or may not be operated inside the liquid storage chamber Ma, and in the present invention, the driving member 120a linearly reciprocates at a position close to the first liquid outlet 131a to change the pressure inside the liquid storage chamber Ma. Specifically, in the case that the driving member 120a moves towards the first liquid inlet 134a, the cleaning liquid outside the liquid storage cavity Ma moves towards the first liquid inlet 134a under the driving of the driving member 120a, so as to drive the cleaning liquid in the liquid storage cavity Ma to flow to the cleaning area through the first liquid outlet 131 a. The mechanism 500a with linear reciprocating motion capability may be an air cylinder, a push-pull electromagnet, an electric push rod, a lead screw, etc., and the mechanism may be determined according to actual use conditions.

In the present invention, the magnitude relationship between the driving member 120a and the first liquid inlet 134a includes the following conditions: in the first case, the longitudinal section of the driving member 120a is larger than the longitudinal section of the first liquid inlet 134a, as shown in fig. 19, in which case the driving member 120a cannot travel into the liquid storage chamber Ma, and the limit positions of the driving member 120a are: the position of the driving member 120a is opposite to the first liquid inlet 134a, when the driving member 120a moves to the limit position, the driving member 120a completely covers the first liquid inlet 134a, the driving member 120a is opposite to the first liquid inlet 134a, the liquid storage cavity Ma is closed, and the pressure intensity is larger. In a second situation, please refer to fig. 20, the longitudinal section of the driving member 120a is equal to the longitudinal section of the first liquid inlet 134a, when the driving member 120a moves to the limit position, the driving member 120a is located in the liquid storage cavity Ma, and the edge of the driving member 120a is attached to the inner wall of the liquid storage cavity Ma, so as to better push the cleaning liquid in the liquid storage cavity Ma to flow to the first liquid outlet 131 a. In a third situation, please refer to fig. 21, the longitudinal section of the driving member 120a is smaller than the longitudinal section of the first liquid inlet 134a, when the driving member 120a moves to the limit position, the driving member 120a is located in the liquid storage cavity Ma, and a gap exists between the driving member 120a and the inner wall of the liquid storage cavity Ma, so that there is no friction between the driving member 120a and the inner wall of the liquid storage cavity Ma during the movement process, and the problem of jamming between the driving member 120a and the liquid storage cavity Ma does not occur.

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.
