The first snap structure 1211 includes at least one first tooth portion, and the second snap structure 1222 includes at least one second tooth portion. The utility model discloses in, first joint structure 1211 includes a plurality of first tooth portions, and the bottom of rotating head 121 is located to a plurality of first tooth portion rings, and the tooth height of each first tooth portion is the situation that increases gradually on the first direction, and second joint structure 1222 includes a plurality of second tooth portions, and the top of joining in marriage joint 122 is located to a plurality of second tooth portion rings, and the tooth height of each second tooth portion is the situation that reduces gradually on the first direction, and the quantity of first tooth portion equals with the quantity of second tooth portion. Each first tooth portion has two end portions in the rotation direction of the rotating head 121, which are defined as a tooth low end P1 and a tooth high end Q1, and the tooth height of the tooth high end Q1 is greater than the tooth height of the tooth low 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 second tooth portion has two end portions in the rotation direction of the rotating head 121, and the two end portions 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 is in contact with the tooth height end Q1 of the first tooth portion, so that the adaptor 122 and the spin head 121 rotate synchronously. When the spin 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 cannot be brought into abutting engagement with each other, and in this case, the frictional force between the adapter 122 and the spin head 121 is smaller than the rotational power of the spin head 121, and the adapter 122 cannot rotate along with the spin head 121, and the adapter 122 is disengaged from the spin head 121. It can be seen that the first and second latch structures 1211 and 1222 are engaged only when the rotator head 121 rotates in a first direction, so that the actuating member 130 supplies water to the cleaning region; when the rotator head 121 rotates in the second direction, the first and second latch structures 1211 and 1222 are disengaged to stop the water supply from the actuator 130.

The base shell 110, the actuator 130, the elastic element 140 and the guiding column 150 are disposed in the first cavity 210 so that the cleaning liquid in the first cavity 210 can be delivered to the cleaning cloth 420 through the first liquid inlet 134, the first liquid outlet 131 and the water outlet 312 in sequence.

The second embodiment:

referring to fig. 16 to fig. 19, the only difference between the present embodiment and the first embodiment is: the liquid supply assembly 100a has different structures, and in this embodiment, the liquid supply assembly 100a includes a base housing 110a, a driving member 120a, an actuating member 130a, and a guide post 150a. The base housing 110a is hollow inside and open-ended to form a liquid passage for the cleaning liquid to be delivered upward to the washing member 300 a. The bottom of the base shell 110a is provided with a conical surface structure, and the conical surface structure is provided with a plurality of second liquid inlets 111a for feeding liquid. The base shell 110a can have better stability when being placed in the barrel 200a by providing the above-mentioned tapered surface structure. The actuator 130a is disposed at the bottom of the driving member 120a and is received in the base housing 110a to form a whole with the driving member 120a and then rotate synchronously with the driving member 120 a. The guide posts 150a are received in the base housing 110a and are distributed in the vertical direction for supporting the driving member 120a and the actuating member 130a. The cleaning element 300a has a water outlet 312a opposite to the top opening of the base shell 110a, the top opening of the base shell 110a is a liquid outlet of the liquid channel, and the driving element 120a is exposed at the top of the cleaning element 300a through the water outlet 312 a.

In this embodiment, the actuator 130a is an impeller, the outer sidewall of the actuator 130a is provided with blades 131a spirally distributed in the vertical direction, the actuator 130a is located in the liquid channel, and the cleaning liquid in the liquid channel is delivered to the cleaning cloth 420a through the water outlet hole 312a in response to the rotational movement of the driving member 120 a. The actuator 130a further has a through hole for the guiding post 150a to pass through, the through hole extends along the rotation axis of the driving member 120a, and the bottom of the driving member 120a is recessed upward at a position corresponding to the through hole to form a groove. After the driving element 120a and the actuating element 130a are integrally formed, the actuating element is sleeved on the guiding post 150a and can rotate relative to the guiding post 150a, and the top of the guiding post 150a extends into the groove and abuts against the driving element 120 a. When the cleaning head 400a is placed on the cleaning member 300a and the driving member 120a is rotated, the cleaning liquid in the liquid channel flows to the cleaning cloth 420a.
