The aperture of the first opening 811 can be smaller than that of the second opening 812, the cleaning liquid vapor is sprayed out from the first opening 811 with the smaller aperture and impacts the water retaining wall 813 at high speed, the water retaining wall 813 can give a certain buffer to the cleaning liquid sprayed out from the first opening 811, so that the cleaning liquid is sprinkled in the inner cavity 81, the whole water outlet groove 80 can be better and more fully filled, the cleaning liquid in a vapor state can be gathered into flowing liquid cleaning liquid after being impacted on the water retaining wall 813, and the liquid cleaning liquid flows out from the second opening 812 in a liquid manner.
As shown in fig. 3, the water blocking wall 813 is preferably a sloped wall that slopes from top to bottom in a direction away from the first opening 811. The cleaning liquid sprayed from the first opening 811 can hit the water blocking wall 813 and then fall off the water blocking wall 813, and the inclined water blocking wall 813 can provide a large water blocking area and can cause the cleaning liquid to change the flow direction and fall off from multiple directions into the inner cavity 81, fill the inner cavity 81, and flow out of the second opening 812.
Of course, as another alternative, the water blocking wall 813 may be a curved surface, an upright wall surface, a special-shaped surface, or the like, and this embodiment is not limited as long as the blocking force can be provided for the cleaning liquid sprayed from the first opening 811, and the cleaning liquid sprayed from the first opening 811 is prevented from being directly sprayed from the second opening 812.
