Abstract
The utility model discloses an explosion-proof device of an electric heating faucet and relates to the technical field of electric heating. The explosion-proof device of the electric heating faucet comprises a body cover, an antifreeze pad, and a pressure spring. The body cover comprises a seal groove, a spring seat, and a vent hole. The antifreeze pad comprises a U-shaped gasket, and a circular spacer. The U-shaped gasket and the circular spacer are in a monolithic structure. The pressure spring is fixed on the spring seat in a pagoda type structure. When the pressure spring and the antifreeze pad are arranged on the body cover, the body cover is arranged on one side of the heating cavity of the faucet body. The antifreeze pad has a sealing effect. Due to the fact that spring pressure is similar to the pressure of heated water, a hot type electric heating faucet can work regularly under the normal temperature condition. When temperature is dropped to a freezing point, the heated water is swelled in size because of icing, the pressure spring and the antifreeze pad are compressed, and air is vented from the vent hole. Therefore, volume expansion is relived and faucet body burst is avoided.
Description
Technical field
The utility model relates to a kind of instant electric water tap, is a kind of electric hot water tap flameproof apparatus with explosion prevention function specifically.
Background technique
At present, known instant electric water tap, formed by faucet body and flow control switch, faucet body mainly adopts the engineering plastics molding and forming, is provided with heating chamber and electrical equipment control chamber in the faucet body, separates with seal diaphragm between heating chamber and the electrical equipment control chamber, be provided with heating pipe in the heating chamber, be provided with heater circuit plate, electric switch and insulation hydraulic pressure switch in the electrical equipment control chamber, the insulation hydraulic pressure switch is connected with electric switch is terminal, and heating pipe is connected with heater circuit plate circuit.When flow control switch is opened, pass into water in the heating chamber, water flow pressure acts on the insulation hydraulic pressure switch, it is closed to make the insulation hydraulic pressure switch promote electric switch, the heater circuit of heating pipe is connected, heating pipe begins the water of the heating chamber of flowing through is heated, and heated water flows out through the water outlet of faucet body.This electric hot water tap has that volume is little, cost is low, quick heating, hot water is with opening with the advantage of coming, but, defective is also very obvious, in winter during mercury dropped, the remaining water in this Instant heating type electric faucet body will cause volumetric expansion because freezing, and faucet body is because of expansion explosion or the misoperation of insulation hydraulic pressure switch, and a kind of volumetric expansion, electric hot water tap flameproof apparatus simple in structure really can alleviated not yet occurs on the market.That is to say that existing instant electric water tap product exists the potential safety hazard defective of the icing rear explosion of low temperature.
Summary of the invention
Task of the present utility model is to provide a kind of and helps to prevent that low temperature from freezing, electric hot water tap flameproof apparatus simple in structure, and this electric hot water tap flameproof apparatus can not only be at trouble free service under the ultra-low temperature surroundings, and can be at trouble free service under the normal temperature environment.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts provides a kind of electric hot water tap flameproof apparatus, comprise body cap, antifreeze pad, pressure spring, described body cap comprises seal groove, spring seat, exhaust hole, described antifreeze pad comprises U-shaped packing ring, round pad, be monolithic construction, described pressure spring is fixed on the spring seat, is pyramid-like structure.
Of the present utility model further to be set to described body cap be round structure, adopts the engineering plastics molding and forming, and seal groove is U-shaped structure, be arranged on the body cap inboard, exhaust hole, spring seat are arranged on the body cap center, and spring seat is tubular structure, are used for the fixation pressure spring.
Of the present utility modelly further be set to described antifreeze pad and adopt silica gel material hot-forming, U-shaped packing ring, round pad are installed on the body cap seal groove for being monolithic construction, and U-shaped packing ring and seal groove are identical.
Of the present utility modelly further be set to described pressure spring one end and be arranged on antifreeze pad lower end surface, the other end is fixed on the spring seat, adopts steel wire wound.
The beneficial effects of the utility model are: be installed in faucet body heating chamber one side after body cap is loaded onto pressure spring, antifreeze pad, the antifreeze seal action that paves, when under the normal temperature state, working, because the pressure of spring is similar to the pressure of healed water, the instant electric water tap can work; When mercury dropped during to freezing point, healed water is because of the volumetric expansion of freezing, pressure spring is compressed with antifreeze pad, gas is discharged from the exhaust hole, reach the purpose of alleviating volumetric expansion, preventing the faucet body explosion, compare safe and reliablely with the instant electric water tap on the existing market, enjoy people to favor.
