Abstract
The utility model relates to an electric heating bag with an anti-explosion device, belonging to the electric heating bag in the domestic appliance field. The utility model comprises a heating preservation bag body which is provided with the heating storing liquid, a heating core arranged in the bag body and a socket head fixed on the heating preservation bag body. An anti-explosion device is also arranged in the bag body, and is composed of a sealing seat, a control board, a push rod, a leather bowl, a brass sheet, a static contact point and a dynamic contact point. The static contact point is fixed on one end of the control board. The control board and the leather bowl are fixed together through the sealing seat. The push rod is fixed on the leather bowl. One end of the brass sheet is fixed on one end of the control board without the static contact point, and the static contact point is fixed on the other end of the brass sheet. The structural design is reasonable, and the hidden troubles of the arc drawing and the flashover of the contact point, etc are avoided by adopting the mechanical form. Not only the high-temperature protective action can be played, but also the pressure protective action can be played. The safety is greatly raised. The utility model can replace the using of the existing electric heating bag.
Description
Affiliated technical field:
This utility model relates to a kind of electric heating bag that is used to warm oneself, and belongs to household appliance technical field.
Background technology:
The temperature control of electric warming bag of the prior art is finished by temperature controller, promptly when reaching design temperature, circuit is cut off in the temperature controller action, this class thermo bimetal temperature sensitive type temperature controller adopts thrermostatic bimetal-plate to make dish shape temperature-sensing element, utilizes the butterfly shaped dual metal sheet temperature-sensing element to produce the moment dancing principle of suddenling change under temperature action, effect by mechanism, contact is moved rapidly, reach the purpose that is switched on or switched off circuit, control circuit.But under long-time the use, contact is tired easily, and the dancing distance of bimetal leaf is too short, and arcing easily burns out the contact even the situation that flashover can not cut off the power supply may occur.In addition, because existing electric warming bag product temperature controller all is to be sealed in the middle duct in the plastic stent with resin glue, affinity between resin glue and plastics is poor, the coefficient of expansion of the two is different again, heating-the cooling that in water, goes round and begins again, the gap can occur, water is infiltrated in the temperature controller, cause temperature controller malfunctioning.After above-mentioned situation occurring, cause to continue energising, the heat generating core continuous operation makes the interior temperature of liquid of insulation bag continue to rise, and produces a large amount of water vapour and other gases, and warm handbag has hidden peril of explosion.
Summary of the invention:
The purpose of this utility model provides a kind of electric heating bag with explosion-protection equipment just at above deficiency of the prior art.
The electric heating bag of this band explosion-protection equipment comprise be equipped with the storage hydrothermal insulation bag, be arranged on the heat generating core in the bag and be fixed on the socket head that is incubated on the bag, it is characterized in that in described bag, also being provided with an explosion-protection equipment, described explosion-protection equipment is by seal receptacle, panel, push rod, leather cup, copper sheet, static contact and dynamic contact constitute, static contact is fixed on an end of panel, panel and leather cup are fixed together by seal receptacle, push rod is fixed on the leather cup, one end of copper sheet is fixed on panel not to be had on the end of static contact, and static contact is fixed on the other end of copper sheet.
Down, leather cup outwards protrudes this utility model in working order, and static contact closely contacts with dynamic contact, energized, the heat generating core heating power stores up hydrothermal temperature and rises gradually, produce steam and other gas, bag interior pressure is constantly increased, and when the intravital pressure of insulated bag reached leather cup setting intensity, leather cup outwards overturn, drive push rod and promote copper sheet, cause static contact and dynamic contact to disconnect, cut off the electricity supply, heat generating core stops heating.Along with the temperature of insulation bag reduces gradually, pressure descends in the bag, sets intensity when following when pressure drops to leather cup, and leather cup resets, and drives push rod copper sheet is resetted, and its static contact closely contacts with dynamic contact, energized, and heat generating core begins again to heat.Electric heating bag is worked so again and again, has avoided the bag too high pressure to cause the electric heating bag blast.
Prior aries such as this utility model and thermo bimetal's temperature sensitive type temperature controller are compared, and have following advantage: 1, reasonable in design, adopt mechanical type, and avoided the hidden danger of contact arcing flashover etc.2, machine power of the present utility model changes and the intrinsic pressure strongly consistent of insulation bag, can not have the phenomenon of hysteresis.3, this utility model not only can play the high temperature protection effect, can also play the pressure protective effect.4, by the pressure electric warming bag of letting slip by mistake, the pressure of electric warming bag increases electric warming bag under the energising situation, also can make outwards upset and cutting off the power supply of leather cup.Safety improves greatly.
The utility model is described in further detail below in conjunction with accompanying drawing.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an explosion-protection equipment structural representation of the present utility model.
The specific embodiment:
Referring to Fig. 1～2, the electric heating bag of this band explosion-protection equipment comprises the insulation bag 1 that heat accumulation liquid 2 is housed, be arranged on the heat generating core 5 in the bag and be fixed on the socket head 3 that is incubated on the bag 1, in described bag 1, also be provided with an explosion-protection equipment 4, described explosion-protection equipment 4 is by seal receptacle 7, panel 8, push rod 9, leather cup 10, copper sheet 11, static contact 12 and dynamic contact 13 constitute, static contact 12 is fixed on an end of panel 8, panel 8 and leather cup 10 are fixed together by seal receptacle 7, push rod 9 is fixed on the leather cup 10, one end of copper sheet 11 is fixed on panel not to be had on the end of static contact, and static contact 12 is fixed on the other end of copper sheet 11.The socket head 3 that is fixed on the insulation bag 1 connects together by seal receptacle 7 and explosion-protection equipment 4, and the panel 8 in socket head 3, heat generating core 5 and the explosion-protection equipment 4 is linked to be electric loop by power lead 6.Explosion-protection equipment also can be separated with socket head, is arranged on other places of bag separately.
Down, leather cup 10 outwards protrudes in working order, and static contact 12 closely contacts with dynamic contact 13, heat generating core 5 heating powers, the temperature of heat accumulation liquid 2 rises gradually, produces steam and other gas, and bag interior pressure is constantly increased, when the intravital pressure of insulated bag reaches leather cup 10 setting intensity, leather cup 10 outwards overturns, and drives push rod 9 and upwards promotes copper sheet 11, causes static contact 12 and dynamic contact 13 to disconnect, cut off the electricity supply, heat generating core 5 stops heating.Along with the temperature of heat accumulation liquid 2 reduces gradually, pressure descends in the bag, sets intensity when following when pressure drops to leather cup 10, leather cup 10 resets, and drives push rod 9 and descends, and copper sheet 11 resets, static contact 12 closely contacts with dynamic contact 13, energized, and heat generating core 5 begins heating again.Electric heating bag is worked so again and again, has avoided the bag too high pressure to cause the electric heating bag blast.
