Electric heater with heat preservation function

Abstract

The invention discloses an electric heater with a heat preservation function. The electric heater comprises an electric heater body. The top of the electric heater body fixedly communicates with an exhaust pipe. A sewage outlet is formed in the bottom of the electric heater body. A sealing plug is arranged in the sewage outlet. One end of the electric heater body fixedly communicates with an air inlet pipe, and the other end of the electric heater body is fixedly connected with a filter screen. The air inlet pipe is located in the filter screen. A heat preservation layer is fixedly connected to the inner wall of the electric heater body. The inner wall of the heat preservation layer is fixedly connected with two sets of symmetrical limiting blocks. The electric heater with the heat preservation function can effectively store heat, the situation that heat is lost too fast is effectively avoided, resource waste is effectively avoided, the heat preservation effect is good, the heat utilization rate is high, blockage of the electric heater is effectively avoided, the situation that the electric heater is burnt out is effectively avoided, the resource utilization rate is high, and the thermal stability is high.

Description

technical field [0001] The invention relates to the technical field of electric heaters, in particular to an electric heater with heat preservation function. Background technique [0002] Electric heating is the process of converting electrical energy into heat energy. Since the discovery that the power supply can produce thermal effects through wires, many inventors in the world have been engaged in the research and manufacture of various electric heating appliances, which are used to raise the temperature of flowing liquid and gaseous media, Insulation and heating, when the heating medium passes through the heating chamber of the electric heater under pressure, the principle of fluid thermodynamics is used to uniformly take away the huge heat generated by the electric heating element during work, so that the temperature of the heated medium meets the user's process requirements. After the existing electric heater is powered off, the heat loss is too fast, the heat preserva...
