Abstract
The invention provides an external optical wave heating type electric water heater provided with a water flow switch with a pressure reduction function and a non-metallic injection molding water tank. A water tank 8 is made of non-metallic materials through the injection molding technique, and the water flow switch 4 with the pressure reduction function is installed in a water inlet pipeline of the water tank and is composed of a component A and a component B. According to the component A, a water inlet channel and a water outlet channel in a body 4-1 are separated by a cover plate 4-2 instead of directly communicating with each other; and when water flows in the component A, the water can forcibly push the cover plate 4-2 and make the movable contact 4-9 and a static contact 4-8 be in contact or make a microswitch 4-7 be turned on, and a circuit is closed. According to the component B, a transverse through hole is formed in the small end of a piston 4-12, and a hole is further formed in the middle of the piston 4-12; when water enters the component B, the water passes through the transverse hole and enters the water tank from the middle hole of the piston 4-12; and when the pressure in the water tank is increased, backpressure is generated at the big end of the piston 4-12, the piston is made to move, and the opening degree of a water inlet 4-14 is decreased or even the water inlet is closed. According to the heating way, a halogen or carbon fiber electric heating pipe is installed in air in a stainless steel sleeve for achieving heating.
