Abstract
The utility model relates to an electric heating bag, which comprises a bag body, a thermal conductive liquid filled in the bag body, a thermostat immersed in the thermal conductive liquid, a ultra-temperature protector and an electrode, wherein the thermostat and the electrode are respectively connected with the ultra-temperature protector. The utility model is characterized in that: an external pressure type discharge valve is arranged at the bag body. Compared with the prior art, the utility model has advantages of no liquid leakage, safe application and convenient operation.
Description
This utility model relates to the heating apparatus of the warming usefulness of human body.
Meeting arctic weather, people particularly old people, child like using the trick of warm bag, warm quilt.The Electric heating warm bag of usefulness is exercised at current social upper reaches, in the bag liquid is housed, and puts pair of electrodes in the liquid into.Before the use, energized, electrode is with liquid heat.After reaching uniform temperature, cut off the electricity supply, will warm up the bag use of taking away, very easy.But this warm bag has a very big shortcoming, is exactly in use often to have small amount of liquid to overflow in bag, cause clothes to be got wet, even human body skin is scalded.Tracing it to its cause, is because the gag of warm bag inlet can not be twisted too tightly.Otherwise warm bag is through after heating several times, and the gas that retains in the bag is heated and can bursts bag.So liquid just overflows the crack between inlet and gag in the bag.
The purpose of this utility model is in order to solve the deficiencies in the prior art, a kind of Electric heating warm bag that does not in use have liquid to overflow and use safely to be provided.
This utility model is achieved in that a kind of Electric heating warm bag, comprises bag, is contained in the intravital heat transfer oil of bag and is immersed in temperature controller, overheat fusion protector and electrode in the heat transfer oil, and wherein temperature controller, electrode are connected with the overheat fusion protector respectively.In addition, an external-compression type air bleeding valve is housed on the bag.
The structure of external-compression type air bleeding valve is made up of overcoat, valve body, spool, compression spring and annular gas seals.
This utility model compared with prior art has not leakage liquid, advantage safe in utilization, easy to operate.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of external-compression type air bleeding valve of the present utility model;
Fig. 3 is the component diagram of external-compression type air bleeding valve of the present utility model.
Further describe this utility model below in conjunction with accompanying drawing:
The bag of Electric heating warm bag (1) is made with good seal performance and resistant to elevated temperatures plastics, and heat transfer oil (2) is filled in the inside.Electrode (3), temperature controller (4) and overheat fusion protector (5) are immersed in the heat transfer oil (2).Energized, electric current reaches electrode (3) through temperature controller (4) and overheat fusion protector (5).Heat transfer oil (2) is heated, and its temperature height is controlled, generally is controlled at 75 ℃ to 80 ℃ scope by temperature controller (4).If temperature controller (4) is malfunctioning, the overflow fixed temperature, overheat fusion protector (5) will be cut off the electricity supply, and heating stops.Electric heating warm bag in use, bag accumulates many gas in (1).When gases are heated, they expand for these, bursts bag (1) easily.For reducing the pressure in the bag (1), an external-compression type air bleeding valve (6) is housed on the bag (1).The structure of external-compression type air bleeding valve (6) is made up of with annular gas seals (11) overcoat (7), valve body (8), spool (9), compression spring (10).When warm bag expands, must bleed off the gas in the bag.With spillikin roof pressure spool (9), compression spring (10) is compressed, and the annular gas seals (11) that links to each other with spool (9) is moved certain distance, and the gas in the bag is just discharged from crack between annular gas seals (11) and the valve body (8).Through the time about 10 seconds, originally expansible warm bag slowly restores to the original state.Take away spillikin, compression spring (10) resets, and the crack is plugged between annular gas seals (11) and the valve body (8), and gas can not outwards discharge in the bag.This utility model is not established inlet, and gas must could be discharged through external-compression type air bleeding valve (6) in the bag, and the liquid in the bag can not discharged outside the bag with gas under normal pressure.
Claims (2)
1. Electric heating warm bag; comprise bag, be housed in the intravital heat transfer oil of bag and be immersed in temperature controller, overheat fusion protector and electrode in the heat transfer oil; wherein temperature controller, electrode are connected with the overheat fusion protector respectively, it is characterized in that being equipped with on the bag external-compression type air bleeding valve.
2. Electric heating warm bag according to claim 1 is characterized in that the structure of described external-compression type air bleeding valve is made up of valve body, overcoat, spool, compression spring and annular gas seals.
