The outer sleeve pipe is a pipe body which is made of special ceramic materials to prevent the strike when used. Because of the action of the special ceramic materials, the function of the emission of far infrared rays can be achieved.

Description

The film covering type tubular heater

Technical field

The utility model relates to relevant a kind of tubular heater, particularly relates to a kind of parent tube that has, and parent tube can give out the film covering type tubular heater of heat after energising.

Background technology

The tubular heater of commonly seeing shown in Figure 1A, is by one with the made parent tube 10 of glass, and is installed in its inner electric-heating assembly 11, constitutes as heating wire; Again just like shown in Figure 1B, with metal heat-generating pipe 20.

All there is following problem in the tubular heater of commonly seeing:

1, to adorn heating wire in the glass parent tube, because the heat that heating wire sent causes the heat efficiency not good through the obstruct of the gases such as nitrogen of glass parent tube and the inside, and comparatively power consumption; Its parent tube is made with glass simultaneously, and is rather fragile again, breaks easily, produces dangerous.

2, metal heat-generating pipe is owing to be that direct energising back produces heat energy, so though do not have aforementioned glass-based pipe heater and break easily and produce dangerous situation, directly switch on because of the piping that generates heat, do not note that slightly the danger of electric shock is promptly arranged during as if use.

The above-mentioned tubular heater of 3, commonly seeing, because be the employing electrothermal method, that is electric energy converts the mode of heat energy to, and the heat that it sent only has the function of heating, there is no other effect, and because the difficult control of this heat energy often has minus effect to produce, for example, in hair iron, hair is caused the situation of burn.

The problems referred to above because commonly seen, the utility model designer is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge, actively studied innovation, in the hope of founding a kind of new tubular heater, can improve the performance of the electrothermal device of general existing routine, make it have more practicality.Through constantly research, design, and, create the utility model that has practical value finally through repetition test and after improving.

The utility model content

The purpose of this utility model is to provide a kind of film covering type tubular heater, according to this kind film covering type tubular heater of the present utility model, it is by a parent tube, be coated on the Electric radiant Heating Film on the parent tube, and the outer outer tube that is sheathed on Electric radiant Heating Film constitutes, outer tube, can prevent to use and be shocked by electricity with this for to make with special ceramics material.

According to this kind film covering type tubular heater of the present utility model, the result that its outer tube is made with special ceramics material, the effect of special ceramics material by this reaches the function that can send far infrared, avoid because of directly heating the injury that is caused, this is an of the present utility model purpose.

According to this kind film covering type tubular heater of the present utility model, the heat system that its Electric radiant Heating Film energising back is sent can spread out at once, can be as known electrothermal tube, can be subjected to the situation that body and air in tube intercept and influence its efficient, this is a purpose more of the present utility model.

According to this kind film covering type tubular heater of the present utility model, because it has the advantage that tubular heater did not have of commonly seeing, be to make its purposes more extensive, this is an another purpose of the present utility model.

The utility model is to adopt following technological means to realize;

A kind of film covering type tubular heater, be by a parent tube, be coated on the Electric radiant Heating Film on the parent tube, and the outer outer tube that is sheathed on Electric radiant Heating Film constitutes, wherein parent tube can be the microscler body that glass, pottery magnetic or quartz etc. are made, Electric radiant Heating Film is the multi-disc semiconductor thermoelectric film with semi-conducting material manufacturing, its two ends are conductive electrode, the body of its outer tube for making with special ceramics material.

Aforesaid parent tube can be the metal tube through insulation processing.

Aforesaid electric membranous layer is constituted by one or more pieces strip electrothermal films.

The two ends of aforesaid Electric radiant Heating Film have an electrode respectively.

Aforesaid outer tube can send far infrared.

The utility model compared with prior art has remarkable advantages and beneficial effect:

From the above as can be known, this kind film covering type tubular heater of the present utility model has the lifting heating efficiency really, promote heating function, and have more safe effect when making operation, and that these effects can be improved the tubular heater efficient of commonly seeing really is low and the drawback of heating function only arranged.
