Description

Water-saving device

Technical Field

The utility model relates to a water pipe equipment, concretely relates to water economizer.

Background

The mainstream of the water saving device can be divided into two categories, namely a mechanical water saving device (such as a constant-flow water saving device, a faucet water saving device, a shower water saving device, a time-delay self-closing faucet and the like) and an induction type water saving device (such as an induction faucet, a groove type water saving device, an IC card water saving device and the like). The basic working principle of the water saving device of the water tap is that an automatic detection device is composed of a water stop plug, a floating type piston, a spring and the like in a valve core, when the water supply pressure is increased, an inner spring is compressed, the piston drives the water stop plug to move upwards, so that the effective water supply area of a water passage is reduced, the output water flow is reduced, when the water supply pressure is reduced, the inner spring is reset, the piston drives the water stop plug to move in the opposite direction, the effective water supply area of the water passage is increased, the output water flow is increased, and the water stop plug can float up and down along with the change of the water inlet pressure to keep the relative stability of the water outlet flow, so that the.

Techniques for achieving water conservation by adding air to water are known, such as air-injection shower water conservation valves, air-injection toilet flush valves. However, the product has defects that under certain conditions, air cannot be injected, but the air inlet holes spray water outwards, so that the product cannot be used normally, and clothes and furniture are easily wetted, and sometimes even electrical equipment fails; the air input can not be adjusted and controlled, and the water outlet impulsive force is overlarge when the water pressure is high, the noise is large, and the vibration is large.

The invention discloses a water saving device which is called as a water saving device and comprises a valve body and an air inlet hole arranged on the valve body, wherein the Chinese published patent No. CN 108999993A is published on 2018, 12 and 14.A regulating part is arranged on the valve body, and the water saving device is characterized in that the water saving device also comprises a regulating part, and the size of an air inlet channel can be changed by rotating or moving the regulating part until the air inlet channel is closed; the invention overcomes the defects that the size of the air inlet channel of the similar product can not be adjusted and the air inlet channel can not be selectively opened or closed according to the requirement, and is widely suitable for showering, washing and the like.

However, the water economizer has the disadvantages that the water economizer can not be used by burying in a wall because air needs to be sucked, water flow noise is caused by the sucked air, and the water impact force is excessive under the condition that the water pressure is sufficient.
