Abstract
The invention provides an optical wave heating metal water tank electric water heater provided with a water flow sensor with a pressure reduction function. A water tank 8 is made of metal materials. The water flow switch 4 with the pressure reduction function is installed on a water inlet pipeline of the water tank. The water flow sensor 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 main body 4-1 are separated by a cover plate 4-2; and when water flows, the cover plate 4-2 is forcibly pushed by water, so that a movable contact 4-9 and a stationary contact 4-8 are made to make contact or a microswitch 4-7 is made to be turned on, and thus a circuit is closed. According to the component B, a transverse through hole is formed in the small end of a piston 4-12, a hole is further formed in the middle of the piston 4-12, when water inflows, water passes through the transverse through hole and then enters the water tank through the middle hole of the piston 4-12, water is prevented from being blocked in the water inlet process, when the water tank is filled with water or the water inlet amount is larger than the water outlet amount, the pressure in the water tank is increased, back pressure is generated by the big end of the piston 4-12, so that the piston 4-12 is made to move, and accordingly the area of a water inlet 4-14 is decreased or even the water inlet 4-14 is closed.
