Problems solved by technology

In terms of showers, water pipes with longer pipe bodies are usually used, and the installation method is generally vertically installed on the wall. Drain the accumulated water in the lumen in time, and the accumulated water in the lumen will easily deteriorate
When people take a shower next time, the polluted stagnant water in the lumen will be discharged as soon as possible. If the human body comes into contact with the polluted stagnant water, it will cause certain harm to health

Abstract

The invention discloses a reflux valve. A fixed bolt and a bolt cover matched with the fixed bolt are arranged in the reflux valve main body; the fixed bolt is provided with a water outlet; a movable sheet for sealing and cover the water outlet is arranged between the fixed bolt and the bolt cover; the movable sheet is provided with a water guide hole; and the reflux valve body is provided with a drainage hole for leaking reflux water. The reflux valve is applied to a shower sanitary appliance; after a shower product is used up, accumulated water in a pipe cavity can be discharged out of a pipe body in the first time to prevent from threatening the health of the human body because of accumulated water degeneration. The reflux valve is simple to install, has beautiful appearance and is easy to cooperate with various bathroom faucet products.

Description

technical field [0001] The invention relates to a backflow valve, in particular to a backflow valve used in a shower pipe. Background technique [0002] Ordinary faucet spools have been widely used, and are currently widely used in faucets and showers. It is known that the spool uses its movement to achieve direction control, pressure control, or flow control. Among them, these sanitary products These common function spools are being used. The existing spool does not have the function of discharging the accumulated water in the water pipe in time. In terms of showers, water pipes with longer pipe bodies are usually used, and the installation method is generally vertically installed on the wall. Drain the accumulated water in the lumen in time, and the accumulated water in the lumen will easily deteriorate. When people take a shower next time, the polluted stagnant water in the lumen will be discharged immediately. If the human body comes into contact with these polluted s...
