The air suction base 2 is arranged in the accommodating cavity 13, a second air inlet 21 is arranged on the outer wall of the air suction base 2, and the second air inlet 21 is communicated with the first air inlet 14. The sealing member 3 is configured to be in a natural state when water is normally supplied (i.e., low pressure or normal water pressure), and an air inlet passage 31 is formed between the outer wall of the sealing member 3 and the inner wall of the suction seat 2; or, when the water outlet end is blocked, the water outlet end is in an unfolding state, the sealing element 3 is unfolded outwards, and the outer wall of the sealing element is at least partially attached to the inner wall of the air suction seat 2, so that the air inlet channel 31 is closed.

Referring to fig. 1, when water is normally supplied, external air may enter from the first air inlet hole 14, and the air is delivered to the air inlet channel 31 through the second air inlet hole 21, and finally is introduced from the air inlet channel 31 to be mixed with water flow, and the air inlet channel 31 may be a gap between the outer wall of the sealing member 3 and the inner wall of the air suction seat 2. Referring to fig. 2, when the water outlet end is blocked, for example, when the water outlet hole of the water outlet device connected to the air suction device is blocked, the water flow applies pressure to the sealing member 3, so that the inner wall of the sealing member 3 is pressed to open outwards, and the opened sealing member 3 is attached to the inner wall of the air suction seat 2, so that the air inlet channel 31 is closed, that is, air cannot enter the inside of the sealing member 3 to mix with the water flow, thereby preventing the water flow inside from overflowing outwards from the air inlet channel 31.

In summary, in the present embodiment, when water is normally supplied, the air inlet channel 31 can be kept open, so as to ensure the air inlet effect; when the water outlet end is blocked, the air inlet channel 31 can be closed, so that the water flow is prevented from overflowing.

In another embodiment, the sealing member 3 includes a movable portion 32 and a fixed portion 33, an outer wall of the movable portion 32 is in a tapered cylindrical shape, the outer wall is inclined from a water outlet end to a water inlet end, and is sleeved in a water passing cavity of the air suction base 2, and an air inlet channel 31 is formed between the outer wall and an inner wall of the water passing cavity when water is normally passed through. The fixing portion 33 is disposed along the periphery of the movable portion 32, the fixing portion 33 is provided with an assembling groove 331, the air suction seat 2 is inserted in the assembling groove 331, and the fixing portion 33 is tightly abutted against the housing 1, so that the sealing member 3 is sealed with the housing 1.
