Compared with the prior art, the hand warmer has the advantages of convenience in use, safety and low manufacturing cost.
Description
Technical field
The utility model relates to a kind of heating installation.
Background technology
Existing hand warmer mainly contains two kinds, and a kind of is electrothermal, and a kind of is outer heat-water-adding type's.The hand warmer of electrothermal adopts the 220V power supply, is made up of heating, temperature controller, indicator lamp and socket etc.These electric parts are immersed in the liquid (water) for a long time, have certain potential safety hazard, in addition, temperature controller cements also is fatal hazards.Outer heat-water-adding type's hand warmer needs earlier that water is boiled, irritates in the hot-water bag then, uses very inconveniently, and the water capacity in the hot-water bag is easily leaked.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of hand warmer of employing electromagnetic oven heating of easy to use, safe, low cost of manufacture.
The utility model is achieved in that and comprises sealed volume, is potted in heat accumulation liquid in the sealed volume, can up and downly be arranged on heating iron plate on the sealed volume inner bottom surface, be arranged on the positioner in the sealed volume.When needing heating heat accumulation liquid, the present invention is placed on the electromagnetic oven, start electromagnetic oven, by heating iron plate heating heat accumulation liquid, rising along with the heat accumulation fluid temperature, its thermal energy drives the heating iron plate and rises, after rising to setting height, positioner should heat the iron plate location, and it can not be fallen at short notice, because the heating iron plate is away from electromagnetic oven, make electromagnetic oven no longer to heating iron plate effect heating, avoided the appearance of phenomenon of the temperature overheating of heat accumulation liquid, and, electromagnetic oven meeting automatic disconnection is no longer worked.
Here, positioner is the bimetal leaf of bending, and a wherein end of bimetal leaf is connected with the heating iron plate, and the other end is in free state.Like this, behind heat accumulation liquid heat temperature raising, bimetal leaf is because the thermal coefficient of expansion difference of two kinds of metals, the amount that expands is also different, causes bi-metal plate deformed, and the bimetal leaf of bending struts, free end jack-up with the heating iron plate, make the heating iron plate gradually away from electromagnetic oven, until the sphere of action of leaving electromagnetic oven, at this moment, the electromagnetic energy that the heating iron plate is no longer accepted electromagnetic oven heats heat accumulation liquid, make heat accumulation liquid can obtain enough heating heats, simultaneously, avoided the transition heating again.And the radian size of the metal material by selecting bimetal leaf or the bending of bimetal leaf is controlled the temperature of heat accumulation liquid.Simple in structure, control makes things convenient for again.
Perhaps, positioner is arranged on the permanent magnet of sealed volume inner top.Like this, after the heat accumulation fluid temperature rises to a certain degree, the thermal energy of heat accumulation liquid drives the heating iron plate and rises, after rising to setting height, held by permanent magnet, make the heating iron plate stop heating away from the scope of electromagnetic oven effect, thereby realize that heat accumulation liquid can obtain enough heating heats, simultaneously, avoided the purpose of transition heating again.In order to make the heating iron plate recover heating function easily, sealed volume inner top above the heating iron plate is provided with button, like this, pass through push button, just can be with heating iron plate top from permanent magnet, make the heating iron plate drop on the sealed volume inner bottom part again, accept the effect heating heat accumulation liquid of electromagnetic oven.Be provided with the button guide holder that has guide hole at the sealed volume inner top, the sealed volume wall of corresponding guide hole is a flexible plastic sheet, and button is slidingly arranged in the guide hole.Like this, push button by flexible plastic sheet, just can be with heating iron plate top from permanent magnet.
Perhaps, positioner is arranged on the thermal expansion material of heating below the iron plate.Utilize the expansion of thermal expansion material to increase, the heating iron plate is pushed away outside the sphere of action of electromagnetic oven.When stopping to heat, postpone the time that the heating iron plate falls after rise.
In order to guarantee that heating iron plate has enough up and down spaces, sealed volume is the hard plastic shell cavity volume.
Compared with the prior art the utility model has easy to use, safe, advantage of low manufacturing cost.

The specific embodiment:
Now in conjunction with the embodiments the utility model is done and is described in further detail:
Embodiment 1: as shown in Figure 1, the utility model comprises sealed volume 1, be potted in heat accumulation liquid 2 in the sealed volume 1, the seat 8 of an end by having rotating shaft up and downly is arranged on heating iron plate 3 on sealed volume 1 inner bottom surface, be arranged on the positioner 4 in the sealed volume 1.Positioner 4 is the bimetal leafs that are bent into the spring round, like this, the free-ended amplitude of fluctuation of bimetal leaf is big, the rising amplitude that helps temperature, the diameter of the turn 4a of the bimetal leaf 4 of spring round in 5 pairs of electromagnetic ovens heating iron plate, 3 operating distance scopes, like this, the turn 4a of the bimetal leaf 4 of spring round just can be arranged on heat iron plate 3 below, a wherein end of bimetal leaf 4 is connected with heating iron plate 3, and the other end is in free state.As shown in Figure 1, along with the heating of electromagnetic oven 5, the free end of bimetal leaf 4 is stretched over B and C point by the A point, and along with further heating, bimetal leaf 4 continues to stretch, and an end that is connected with heating iron plate 3 is increased to D point (as shown in Figure 3).When stopping to heat, postpone the time that heating iron plate 3 falls after rise.
Embodiment 2: as scheming: shown in 2, present embodiment is on the basis of embodiment 1, and positioner 4 is arranged on the permanent magnet of sealed volume inner top.Sealed volume 1 inner top above heating iron plate 3 is provided with button 6.Be provided with the button guide holder 9 that has guide hole 7 at sealed volume 1 inner top, the sealed volume wall 1a of corresponding guide hole 7 is flexible plastic sheet, and button 6 is slidingly arranged in the guide hole 7.
Embodiment 3: as shown in Figure 4, present embodiment is on the basis of embodiment 1, the diameter of the turn 4a of the bimetal leaf 4 of spring round is outside 5 pairs of heating of electromagnetic oven iron plate, 3 operating distance scopes, like this, the turn 4a of the bimetal leaf 4 of spring round will stagger to be provided with or to be provided with on heating iron plate 3 and wear groove turn 4a is passed with heating iron plate 3, to guarantee that heating iron plate 3 is in the operating distance scope of electromagnetic oven 5.
