Abstract

The utility model relates to a thermostatic automatic plug for thermos bottles. Boiled water is pumped to a water outlet by a water pump in the bottle plug of a thermos bottle using electricity as the motive power. The bottom of the bottle plug of the thermos bottle is provided with an electric heating component and a switch controlled by temperature, and the double-metal sheet type switch controlled by temperature is connected with the electric heating component in series.

Description

Thermostatic automatic plug of thermos bottle

The utility model belongs to the small stores class.

Existing gas-pressure thermos bottle adopts a hot water conduit to be inserted into the bottom of thermos bottle glass liner, and the user forms the interior high pressure of thermos bottle glass liner with the piston on the hand thermos bottle bottle stopper, and hot water is flowed out; This method is relatively required great effort, and piston is not easy sealing, also often the incrustation scale of thermos bottle bottom is ejected, and can not satisfy hygienic requirements.Existing electric heating thermos bottle does not have the constant temperature heat insulation function usually, and water temperature descended much after the hot water in the thermos bottle was placed a night, can not satisfy the demand in many special places, such as the punching out soup, and soya-bean milk juice or instant noodles etc.

The purpose of this utility model is that the hot water in the thermos bottle is often remained near the temperature of closing on boiling, and boiling water flows out automatically when water.

The purpose of this utility model is achieved in that in the bottom of thermos bottle bottle stopper installs a cover automatic constant temperature heating device, automatically water is heated be lower than the temperature of regulation in water temperature after; The top installation one cover water pump of heater relies on electric strength, the outside of heat-exchanger pump to thermos bottle after the energising.

The utility model is owing to installed water pump in the thermos bottle bottle stopper, the user can add water very easily in teacup or other containers, and the water temperature of hot water often remains near the boiling point.

Below in conjunction with drawings and Examples the utility model is described further.

1 electric heater and temperature sensor in the drawings, 2 conical valves and electromagnetic core, 3 pistons, 4 electromagnet coils, 5 thermos bottle bottle stopper rods, 6 check valve valve blocks, 7 springs, 8 bottle stopper supports, 9 switch depression bars, 10 outlet pipes.

Electric heater and temperature sensor (1) manufacture an entity in the drawings, and heating wire is connected with the double-metal sheet type temperature sensor circuit, and when water temperature during near boiling point, the distortion of bimetal leaf strengthens circuit and disconnects; When the temperature of water was lower than the temperature of regulation, the distortion of bimetal leaf reduced, and circuit is connected, thereby the water temperature in the heating wire heating assurance thermos bottle is often near boiling point.Conical valve (2) also is the iron core of electromagnet simultaneously, moves reciprocatingly under the alternation magnetic force of electromagnet coil (4); Electromagnetic core leads to 50 hertz of alternating currents (civil power), produces alternating magnetic field.When conical valve and electromagnetic core (2) reciprocating motion, piston (3) also moves reciprocatingly with conical valve (2), but because the difference of material is different with the position of relative coil, their relative position has certain variation; When conical valve (2) when moving downward, piston also moves downward under the promotion of gravity and magnetic force, but do not have that conical valve walks far away, thereby the opening of two parts in conjunction with the conical surface, water enters into plunger shaft; Conical valve (2) is when moving upward, and the conical surface of it and piston is airtight, and the water that drives in piston (3) the compressing plunger shaft upwards flows; The water at upper reaches is washed check valve valve block (6) open and is flowed to effluent pipe mouth (10); When electromagnetic core moved downward once more, check valve valve block (6) was lived the valve block end face at the pressure effect lower seal of gravity and spring, and current can not be refluxed.Solenoid (4) provides reciprocating driving force for electromagnetic core (2); Bottle stopper rod (5) supports each heater block and water pump; Bottle stopper support (8) supports the part miscellaneous of whole system; The inner of switch depression bar (9) is a switch open in usual, as user during the edge pull switch depression bar (9) of water tumbler, and solenoid (4) energising, pump working pumps boiling water for the user.

Claims

1, constant temperature automatic hot-water bottle bottle stopper flows out along conduit as power drive hot water with electricity, it is characterized in that: electric water pump (2) is installed in the bottle stopper (5) of thermos bottle.

2,, it is characterized in that constant temperature electric heater (1) being installed in the bottom of thermos bottle bottle stopper (5) by the constant temperature automatic hot-water bottle bottle stopper described in the claim 1.
