Abstract

The utility model relates to the electric heating technical field, in particular to a heating element delivering heat air, comprising at least two high temperature resistant glass tubes which have different diameters and are communicated up and down, inner surfaces and outer surfaces of the glass tubes are coated with electric heating films, both ends of the glass tubes are coated with the electroconductive silver colloid, the glass tubes which are different in diameter are of concentric nesting and have both ends connected with and fixed on conducting strips respectively, two conducting strips are connected with each other by a wire; the heating element applying the structure has the advantages of large heating surface, high heat efficiency and good heat dissipation effect; the heating surface is parallel to the wind direction, thereby the wind resistance is low; due to the healthy characteristics of the electric heating film, the electric heating film does not generate electromagnetic radiations which are dangerous to human bodies, but can generate far infrared biological waves which are healthy to human bodies; because the spraying film surface is the surfaces of the column-shaped glass tubes, the spraying film is of no resistance, the impedance is easy to control, which is convenient for manufacture. Therefore, the utility model is an ideal heating element delivering heat air for electric drier, etc.

Description

But the heating element of heat air delivery

Technical field:

The utility model relates to the heating element technical field, but refers in particular to a kind of heating element of heat air delivery.

Background technology:

At present, the employed hair dryer of people etc. is used to carry the electrical appliance of hot-air, all uses heating wire as its heater element mostly, also has minority to use and is coated with the honeycomb fashion pottery of Electric radiant Heating Film as its heater element.Yet test shows: though electrothermal wire heating's element is a kind of resistance heating element, also have inductance characteristic simultaneously, in use can produce harmful electromagnetic radiation, harm user's health; Sprayed the honeycomb fashion pottery of Electric radiant Heating Film, though can not produce electromagnetic radiation, its windage is big, area of dissipation is little, and because the structure of its honeycomb fashion brings the inconvenience of spray film, spray membrane impedance to be difficult for shortcomings such as Be Controlled, very inconvenience in the production.

The utility model content:

But the purpose of this utility model is exactly the heating element that a kind of heat air delivery is provided at the deficiency of prior art existence.

To achieve these goals, the technical solution adopted in the utility model is: the high-temperature resistant glass tube that comprises at least two different-diameters, the upper and lower perforation of glass tube, the inside and outside surface-coated of glass tube has Electric radiant Heating Film, the glass tube two ends scribble conductive silver glue, the glass tube of different-diameter is a nested, concentric, and the glass tube two ends are fixed by resistant to elevated temperatures conducting strip edge joint respectively, connect by lead between two conducting strips.

The glass tube of different-diameter is cascaded by conducting strip.

The glass tube of different-diameter is connected in parallel by conducting strip.

The beneficial effects of the utility model are: the heater element of this structure, and its heating is wide, heat efficiency height, good heat dissipation effect; Its heating face is parallel with wind direction, and windage is little; The health characteristic that Electric radiant Heating Film is had self can not produce harmful electromagnetic radiation, and can launch the biological ripple of human body beneficial's far infrared; Its spray face is the surface of cylindrical glass pipe, and without hindrance during the spray film, impedance also is easy to control, is convenient to produce.Therefore, but the utility model is a kind of heater element of desirable heat air delivery equipment such as hair dryer.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a cutaway view of the present utility model;

Fig. 3 is the A place enlarged diagram of Fig. 2.

Embodiment:

See shown in Fig. 1,2,3, the technical solution adopted in the utility model is: the high-temperature resistant glass tube 1 that comprises at least two different-diameters, glass tube 1 upper and lower perforation, glass tube 1 inside and outside surface-coated has Electric radiant Heating Film 2, glass tube 1 two ends scribble conductive silver glue 3, the glass tube 1 of different-diameter is a nested, concentric, and glass tube 1 two ends are fixed by resistant to elevated temperatures conducting strip 4 edge joints respectively, connect by lead between two conducting strips 4.

The glass tube 1 of different-diameter is cascaded by conducting strip 4.

The glass tube 1 of different-diameter is connected in parallel by conducting strip 4.

Some surfaces are coated with the cylindrical high-temperature resistant glass tube 1 of Electric radiant Heating Film 2 by its diameter order from big to small, successively that diameter is less high-temperature resistant glass tube 1 embeds in the bigger high-temperature resistant glass tube 1 of diameter, formation has level, surperficial parallel concentric structure, two ends at each high-temperature resistant glass tube 1 all scribble conductive silver glue 2, with resistant to elevated temperatures conducting strip 4 two ends of this structure are fixed, this structure is inserted the loop on demand promptly can be used as heater element.From Fig. 1 and Fig. 2 as can be seen, resistant to elevated temperatures hard conducting strip 4 and Ge Zhi high-temperature resistant glass tube 1 are all minimum with the area of wind direction vertical plane, and the surface of their roomy areas is all parallel with wind direction, and such combination makes windage minimum; Spray film on the surface of each resistant to elevated temperatures glass tube 1 during the spray film, do not have any obstruction, be easy to control its impedance, be convenient to produce; The heating face of each resistant to elevated temperatures glass tube 1 is very big, heat efficiency height, rapid heat dissipation; The health characteristic that Electric radiant Heating Film is had self not only without any electromagnetic radiation, and can produce the biological ripple of human body beneficial's far infrared.Based on above advantage, the utility model is a kind of heater element of desirable heat air delivery equipment such as hair dryer.

Certainly, the example of the above, it is preferred embodiments of the present utility model, be not to be used for limiting practical range of the present utility model, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
