Abstract
The invention provides an external rapid-heating type electric water heater provided with a water flow sensor with a pressure reduction function and a non-metallic blow-molded water tank. The water tank 8 is made of non-metallic materials through the blow molding technique, and the water flow sensor 4 with the pressure reduction function is installed on a water inlet pipeline of the water tank and is composed of a component A and a component B. According to the component A, when water flows in the component A, the water flow pushes an impeller or a rotor or a Hall element 4-8 to rotate, and a pulse signal or a current signal or a voltage signal or other signals are output by sensing the water flow rate, so that an intermediate relay is started, and a circuit is closed; and when water is stopped, the circuit is opened, and an electric heating pipe stops heating. According to the component B, a transverse through hole is formed in the small end of a piston 4-9, and a through hole is further formed in the middle of the piston 4-9; when water enters the component B, the water passes through the transverse through hole and enters the water tank from the middle hole of the piston 4-9; and when the pressure in the water tank is increased, backpressure is generated at the big end of the piston 4-9, the piston is made to move, and thus the opening degree of a water inlet 4-11 is decreased or even the water inlet 4-11 is closed.
