Abstract
The utility model relates to a shell of a hand warmer, belongs to the technical field of electric appliances and solves the problem of poor heat storage performance of the constant temperature hand warmer in the prior art. The shell of the hand warmer comprises an upper shell and a lower shell; a containing cavity is formed between the upper shell and the lower shell and is used for containing a heating element; the upper shell is also provided with a switch for controlling the circuit to be switched on and off; the lower shell is provided with a power supply interface; the upper shell is made of one of materials of ceramic/purple sands/soil/ABS (acrylonitrile butadiene styrene) plastic; the lower shell is made of one of materials of the ceramic/purple sands/soil/ABS plastic. The shell of the hand warmer is provided with the upper shell and the lower shell which are made of different materials, so the hand warmer is long in energy storage time and good in environment friendliness; a protection layer is arranged at the outside of the shell, so the handfeel of the hand warmer is enhanced, the anti-shock performance of the hand warmer is improved, and the shell of the hand warmer has the advantages of simple structure and convenience in use.
Description
Technical field
This utility model belongs to technical field of electric appliances, relates to the housing of a kind of hand warmer, particularly a kind of hand warmer.
Background technology
Hand warmer product has electric baking pan and the large class of electric hot-water bag two.Wherein, electric baking pan is heat-generating disc, temperature controller, insulation material (heat-preservation cotton), switch and the shell composition by heater element (, heating wire or other exothermic material) composition.Its operation principle is: after switching on power, heater element changes electric energy into heat energy, temperature controller action in the time reaching uniform temperature, and automatic cut-off power, so the heat of electric baking pan inside is outer loose gradually, thereby human body can be obtained transmission heat and warm oneself from electric baking pan.In the time that electric baking pan temperature declines, temperature controller resets, the heating of just can again switching on.
But hand warmer housing of the prior art often adopts plastic material to make, its ageing resistance is poor, and heat storage capacity is poor, is unfavorable for that hand warmer uses the in the situation that of long-term fever.
Utility model content
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of housing of hand warmer.
The purpose of this utility model can realize by following technical proposal: a kind of housing of hand warmer, it is characterized in that, comprise upper shell and lower house, between described upper shell and lower house, form a containing cavity, described containing cavity is interior for placing heater element, on described upper shell, be also provided with the switch of control circuit break-make, described lower house is provided with power interface, described upper shell adopts a kind of material in pottery/purple yarn/earth/ABS plastic to make, and described lower house adopts a kind of material in pottery/purple yarn/earth/ABS plastic to make.
It is strong that pottery/materials such as purple yarn/earth/ABS plastic all have heat storage capacity, be conducive to extend the temperature retention time of hand warmer, and its good looking appearance, upper-lower casing adopts unlike material to make, make its outward appearance more attractive in appearance, and its feel difference of the housing of unlike material, user can select unlike material according to demand.
In the housing of above-mentioned hand warmer, described upper shell outside is provided with heat conduction panel, and described heat conduction panel adopts aluminum material to make.It is light that aluminum material has quality, and cost is low, the advantage of good heat conductivity.
In the housing of above-mentioned hand warmer, described power interface is positioned at the sidepiece of upper shell.
In the housing of above-mentioned hand warmer, between described upper shell and lower house, adopt the mode of gummed to be fixed together.
In the housing of above-mentioned hand warmer, the mode being bolted between described upper shell and lower house is fixed together.
In the housing of above-mentioned hand warmer, described upper shell and lower house outside are coated with the protective layer that flexible material is made.
In the housing of above-mentioned hand warmer, described protective layer is rubber cover.
In the housing of above-mentioned hand warmer, described protective layer is velveteen protective layer.
Compared with prior art, the housing of this hand warmer is by arranging upper shell and the lower house of unlike material, make hand warmer energy storage time long, good environmental protection, utilizes constant temperature unit that this hand warmer can be directly inserted on power supply, long-term charging can be not overheated yet, heat conduction panel is set on housing, plays the effect of local heat conduction, make hand warmer good heat conduction effect simultaneously, can not scald one's hand again, also can not dispel the heat too fast simultaneously.In addition, be provided with protective layer in hull outside, can strengthen the feel of hand warmer, improve the anti-seismic performance of hand warmer simultaneously.There is advantage simple in structure, easy to use.
