It should be understood that the above-described on-off stop device may be used not only with showers, but also with other water outlets.
In the technical scheme, the shower head is closed and stopped immediately when used, so that the outflow of residual water is avoided, and the structure with compact structure, thin thickness and good appearance integrity can be realized. In the water inlet process of the shower head, the water inlet pressure in the water inlet channel 11 acts on the air bag 21 to overcome the elastic force effect to deform and compress the air bag, so that the water storage cavity 3 is gradually compressed, and the air and the residual water in the water storage cavity 3 are discharged to the water outlet cavity 12; when the air bag 21 deforms to a certain degree, the water passing opening 111 is exposed, and at the moment, water in the water inlet channel 11 flows to the water outlet cavity 12 through the water passing opening 111 to realize water outlet; when the water inlet of the shower head is closed again, the water inlet pressure borne by the air bag 21 disappears, and the water storage cavity 3 is reset under the action of elastic force, at the moment, the water storage cavity 3 is restored, and the air pressure in the water outlet cavity 12 is smaller than the external air pressure, so that the water in the water outlet cavity 12 can be pressed into the water storage cavity 3 to be stored under the action of the external air pressure, and the situation that residual water flows out after the water inlet is stopped is avoided, the volume and the sealing performance of the water storage cavity 3 are controllable, the sealing performance is good, the water storage quantity is large, and therefore, the function of storing the residual water is reliable, and the residual water cannot easily fall off; in addition, when water is fed again, the mixed water with proper temperature in the water inlet channel 11 immediately enters the water outlet cavity 12 to be mixed with the residual water at the moment that the residual water enters the water outlet cavity 12 again, so that the situation that the cold residual water drops onto a user body first to cause discomfort of the user is avoided.
The description of the above specification and examples is intended to illustrate the scope of the invention, but should not be construed as limiting the scope of the invention.
