Description

Anti-freezing shower faucet

Technical Field

The utility model relates to an articles for daily use bathroom field especially relates to a gondola water faucet prevents frostbite.

Background

At present, the gondola water faucet is the bathroom product that people daily life is commonly used now, through using the gondola water faucet, except providing a rivers and being used for simple shower, can also adjust water yield and temperature to improve the travelling comfort of shower. The existing shower faucet is generally made of brass and engineering plastics, is not anti-freezing in the use process of the shower faucet, and is easy to frost crack at the temperature below-10 ℃.

Although the anti-freezing shower faucet appears on the market, the actual anti-freezing effect is not good, the shower faucet is easy to freeze, and therefore, the event that a manufacturer pays for a consumer due to frost cracking of the shower also occurs. With the increasing demand, people also expect a shower faucet which can resist the freezing temperature of-20 ℃ or even-40 ℃ and does not have the frost crack.

The main reason that the shower faucet is easy to frost crack is that water is reserved in the shower faucet. At present, a water mixing valve (core) is generally adopted in a shower faucet to control an upper outlet and a lower outlet, but the water mixing valve (core) has the defect that when a cold water inlet and a hot water inlet are closed, the upper outlet and the lower outlet are also closed, so that water reserved in the shower faucet cannot be discharged.
