Specific embodiment

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below Example is not intended to limit the scope of the present invention for illustrating the utility model.

In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is pacified Dress ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally Connection；It can be mechanical connection, be also possible to be electrically connected；Can be directly connected, can also indirectly connected through an intermediary, It can be the connection inside two elements." first " " second " " third " " the 4th " does not represent any sequence relation, be only for The differentiation for facilitating description to carry out.For the ordinary skill in the art, it can understand that above-mentioned term exists with concrete condition Concrete meaning in the utility model.At the time of " current " is when executing certain movement, occur multiple current in text, is at any time Between passage in record in real time.

In order to solve the problems, such as that existing infrared electric heater is larger to user's Ocular irritation, the utility model provides a kind of nothing Light infrared heating pipe and electric heater.

Product, method etc. will be described in detail by basic engineering, extension design and alternative design below.

The utility model provides a kind of unglazed infrared heating pipe, as depicted in figs. 1 and 2 comprising red infrared radiation electrothermal Element 1, conductive component 2 and the filter glass pipe 3 for filtering visible light, wherein red infrared radiation electrothermal element 1 is set to filter glass In pipe 3, the both ends of red infrared radiation electrothermal element 1 are separately connected conductive component 2, insulating end of the conductive component 2 from filter glass pipe 3 It draws.

Red infrared radiation electrothermal element 1 is the electromagnetic wave heating using certain wavelength, and China is traditionally also referred to as far infrared Heating.Since most of organic compounds have strong absorption characteristic to far infrared, it is had using FAR INFRARED HEATING The higher thermal efficiency.Such as helical form or undulating metal silk or carbon fiber exothermic wire.

Red infrared radiation electrothermal element 1 is placed in filter glass pipe 3, and filter glass pipe 3 can be filled into visible light, then infrared The infrared ray that radiation electric heating element 1 issues passes through filter glass pipe 3, it is seen that light is filtered, and user will not be again by visible The stimulation of light, using effect are preferable.

Filter glass pipe 3 can be straight pipe or curved siphunculus, and tubular form is cylindrical or elliptical cylinder-shape, filter out visible Light reaches being used for the function through infrared light.In some embodiments, filter glass pipe 3 replaces existing remote red Outer glass pipe 3.

The both ends of filter glass pipe 3 need to insulate, and red infrared radiation electrothermal element 1 passes through conductive component 2 from filter glass pipe 3 Two insulating ends are drawn.Fig. 1-2 gives specific deriving structure.Wherein red infrared radiation electrothermal element 1 and filter glass pipe 3 are coaxial To setting.The mode that conductive component 2 draws filter glass pipe 3 can be improved filter glass pipe 3 and red infrared radiation electrothermal component The problem of cooperation compactness, the connection of leading-out terminal component is more reliable, avoids the occurrence of poor contact.

In order to which 3 both ends of filter glass pipe progress insulation processing is filtered the filter glass of visible light in some embodiments Close setting insulating top cover 8, conductive component 2 pass through insulating top cover 8 respectively at the both ends of pipe 3.It is arranged on insulating top cover 8 only for conduction The through-hole that component 2 passes through just, to limit and fix conductive component 2 and red infrared radiation electrothermal element 1 in filter glass pipe 3.

It, can be in the optical filtering of filtering visible light in view of the compactness connected between insulating top cover 8 and filter glass pipe 3 is poor Gum cover 7 is set between the both ends and insulating top cover 8 of glass tube 3, as shown in Figure 3.The close of connection is improved by the elasticity of gum cover 7 Property, prevent insulating top cover 8 from sliding.The gum cover 7 is high temperature resistant gum cover, can resist the high temperature of red infrared radiation electrothermal element 1.

The infrared light issued based on red infrared radiation electrothermal element 1 is circumferentially to emit, and the infrared light for being radiated rear is worn It crosses optical filtering glass tube 3 and projects rear, cause greatly to lose, therefore, the internal layer of filter glass pipe 3 is in the infra-red radiation Reflectance coating is arranged in the part at 1 rear of heating element.Infrared light reflection to front can be played the work of heat source by reflectance coating With having saved thermal energy, reduced the loss of infrared energy.

Next provide the specific structure of conductive component 2: the conductive component 2 is conductive sheet, in the longitudinal direction, first End 4 is fixedly connected with red infrared radiation electrothermal element 1, and second end 5 is terminals.It is fixedly connected with red infrared radiation electrothermal element 1 First end can become welding ends, and usually the perforation of the lead and conductive sheet welding ends at 1 both ends of red infrared radiation electrothermal element is worn Later it welds, then conductive sheet is pierced by insulating top cover 8, is then connected with external wiring (i.e. power supply line).

It, can after conductive sheet is pierced by insulating top cover 8 in order to which red infrared radiation electrothermal element 1 and conductive component 2 is effectively fixed To use flame device to preheat 3 both ends of glass tube, high temperature press seal.Press seal is heated between conductive component 2 and filter glass pipe 3.

Certainly, in other examples, can also the middle part of conductive sheet extend in the width direction two it is bent Strip 6, as shown in Figure 4 and Figure 5.Width of the welding ends width of conductive sheet greater than strip 6 when straight, is greater than terminals width, After gum cover 7 and insulating top cover 8 are mounted on 3 mouthfuls of filter glass pipe, bending strip 6 makes insulating top cover 8, gum cover 7 be stuck in strip 6 Between welding end, random movement is avoided.

In response to this, the generally rectangular hole of through-hole on insulating top cover 8, when the width in hole is straight greater than strip 6 Width, be less than welding ends width.

The utility model additionally provides a kind of electric heater comprising above-mentioned unglazed infrared heating pipe.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
