Abstract
The utility model discloses an electric heating device for a hot-water bag, which comprises a heat conduction shell and a heating body arranged in the heat conduction shell. The heating body comprises a positive electrode plate, a negative electrode plate and a heating plate, the heating plate is arranged between the positive electrode plate and the negative electrode plate and is electrically connected with the positive electrode plate and the negative electrode plate, a thermal insulation and heat conduction film with high temperature resistance is arranged between the heating body and the heat conduction shell, and the heating body is sealed in the heat conduction shell; and the heating body adopts a PTC (positive temperature coefficient) plate. Since complete insulation and sealing is adopted between the heat conduction shell and the heating plate, current leakage is avoided. In addition, since the PTC plate is used as a heating material and the constant-temperature heating characteristic of a PTC thermistor is utilized, overheating caused by continuous heating is prevented, and the damage to the hot-water bag and even a human body is avoided. The PCT material has a small thermal resistance and high heat transfer efficiency, the electric heating device can achieve rapid heating and is convenient to use.
Description
Technical field
The utility model relates to a kind of electric heater unit, particularly a kind of electric heater unit that is used for hot-water bottle.
Background technology
Hot-water bottle is as a kind of heating tool and since have volume little, be convenient for carrying, advantage such as heating effect is good, enjoy the people parent to look at for a long time.Existing hot-water bottle mainly comprises common plastic cement hot-water bottle, cloth-plastic hot-water bag and electric hot-water bag several types.Common plastic cement hot-water bottle and cloth-plastic hot-water bag all need manually to irritate hot water when each the use could use, and the use that repeats to pour water bothers, and scalds easily when pouring water, and wastes time and energy, and causes waste to water resources.In order to overcome above-mentioned shortcoming, electric hot-water bag arises at the historic moment, the groundwork principle of electric hot-water bag is: electric heater is set in hot-water bottle, in electric hot-water bag, adorn water then as heat transfer medium, only need energising before each the use, can use after utilizing electric heater that the water in the hot-water bottle heat is heated.Electric hot-water bag since have cleaning, heating soon, water saving, advantage such as easy to use paid close attention to by the consumer always.But electric leakage because that the structure of electric heater is provided with is unreasonable, takes place and causes security incident in electric hot-water bag easily that generally sell on the existing market.Therefore brought mental handicape to the consumer, most of consumer also has to have to take the second best, and continues high common plastic cement or the cloth-plastic hot-water bag of usage safety performance.
At above-mentioned deficiency, need to explore a kind of new electric hot-water bag heater, leaky takes place when preventing to use, avoid the generation of security incident, improve the security reliability of electric hot-water bag.
The utility model content
In view of this, the purpose of this utility model provides and a kind ofly prevents to leak electricity and overheated, quick heating, hot-water bottle heater that heats is good, eliminates the potential safety hazard of electric hot-water bag fully, guarantees user's personal safety.
The purpose of this utility model is achieved through the following technical solutions: a kind of electric heater unit that is used for hot-water bottle, comprise that heat conduction shell and sealing are arranged on the heater in the heat conduction shell, described heater comprises the positive and negative electrode sheet and is arranged between the positive and negative electrode sheet and the heating sheet that is electrically connected with the positive and negative electrode sheet, resistant to elevated temperatures insulating heat-conductive film is set between heater and the heat conduction shell.
Further, the cuboid aluminum hull that described heat conduction shell is a both ends open, the sheathed silica gel sheath in cuboid aluminum hull two ends is filled the refractory seals glue that is used for water-tight in the silica gel sheath;
Further, described heating sheet is the PTC sheet;
Further, described refractory seals glue is that silica gel material is made.
The beneficial effects of the utility model:, prevent that leaky from taking place owing to adopt complete insulated enclosure setting between heat conduction shell and the heating sheet; In addition, adopt the PTC sheet, utilize the PTC thermistor to have the constant temperature heat generation characteristic, prevent its constantly superheating phenomenon of causing of heating, thereby prevent to the damage of hot-water bottle even to the injury of human body as exothermic material; PCT material thermal resistance is little, heat exchange efficiency is high, so programming rate is fast, and is easy to use.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a structural perspective of the present utility model;
Fig. 2 is that A-A among Fig. 1 is to cutaway view.
Embodiment
Fig. 1 is a structural perspective of the present utility model; Fig. 2 is that A-A among Fig. 1 is to cutaway view, as shown in the figure: the electric heater unit that is used for hot-water bottle of the present utility model, comprise that heat conduction shell 1 and sealing are arranged on the heater in the heat conduction shell, described heater comprises positive and negative electrode sheet 2 and is arranged between the positive and negative electrode sheet and the heating sheet 3 that is electrically connected with the positive and negative electrode sheet, resistant to elevated temperatures insulating heat-conductive film 4 is set between heater and the heat conduction shell, and the heater sealing is arranged in the heat conduction shell.Owing to adopt complete insulated enclosure setting between heat conduction shell and the heating sheet, prevent that leaky from taking place, fully guaranteed user's personal safety, eliminated potential safety hazard fully.
In the present embodiment, heat conduction shell 1 adopts the cuboid aluminum hull of both ends open, and the sheathed silica gel sheath 5 in cuboid aluminum hull two ends is filled the refractory seals glue 6 that is used for water-tight in the silica gel sheath, and present embodiment adopts silica gel material to make.Adopt the sheathed silica gel sheath in cuboid aluminum hull two ends, and filling gel seals, simple in structure, easy to process; Utilize the fast characteristics of aluminium heat transfer, the water quick heating during use in the hot-water bottle, the convenient use.Certainly, the heat conduction shell is that cylindrical other shapes that wait all can realize, but also all falls into protection range of the present utility model.
In the present embodiment, described heating sheet 3 is the PTC sheet, fit tightly the PTC sheet between the positive and negative electrode sheet 2, the positive and negative electrode sheet links to each other with extraneous power supply by lead 7, adopt the PTC sheet as exothermic material, utilize the PTC thermistor to have the constant temperature heat generation characteristic, prevent its constantly superheating phenomenon of causing of heating, thereby prevent to the damage of hot-water bottle even to the injury of human body; PCT material thermal resistance is little, heat exchange efficiency is high, so programming rate is fast, and is easy to use.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
