Description
Technical field
The utility model relates to a kind of bulb, relates in particular to a kind of heating bulb.
Background technology
Along with the continuous progress of the development of economy and society, accelerated the demand of people to the illumination series products, so that the application of illumination series products becomes more and more extensive, and incandescent lamp is exactly a kind of in many illumination series products.
Incandescent lamp had once produced irreplaceable effect in normal lighting, it generally comprises lamp holder, lamp housing and heating tungsten filament etc., and after electric current was by the heating tungsten filament, the heating tungsten filament just can emit beam, and realized the illumination purpose of incandescent lamp; Meanwhile, the heating tungsten filament also can produce certain heat when luminous, this heat is dispersed in the external world by lamp housing and goes, thereby so that incandescent lamp can exist when utilizing electric energy to throw light on because of the not high defective that causes the significant wastage of electric energy of efficiency, thereby so that incandescent lamp is little by little replaced to realize saving the purpose of the energy and environmental protection by the LED lamp in the illumination occasion.
And in the heating field, for example when pet box is heated, people but will by the heating tungsten filament of incandescent lamp electric current by the time heat that produces realize purpose that pet box is heated.But when incandescent lamp heated pet box, electric current but was wasted by the luminous energy that the tungsten filament that generates heat converts to, and incandescent lamp can be existed when utilizing electric energy to heat because of the not high defective that causes the significant wastage of electric energy of efficiency.
Therefore, be badly in need of wanting a kind of bulb that generates heat to overcome above-mentioned defective.
The utility model content
The purpose of this utility model is to provide a kind of heating bulb, can improve efficiency to improve heat generation rate and can reduce waste of energy, can also reduce production costs.
For realizing above-mentioned purpose, the utility model heating bulb comprises the insulator of lamp holder, lamp housing, heating wire and mica material.Lamp holder and lamp housing are tightly connected and form an annular seal space, and lamp holder has positive terminal and the anode connector that stretches in the annular seal space; Heating wire and insulator are built in the annular seal space, and an end of heating wire and positive terminal electric connection, and the other end of heating wire twines insulator and is electrically connected with anode connector, is filled with inert gas in the annular seal space.
Preferably, insulator is connected on positive terminal and the anode connector.
Preferably, insulator structure in the form of sheets.
Preferably, lamp holder is provided with the helicitic texture that is connected with extraneous lamp socket.
Preferably, helicitic texture is external thread structure.
Preferably, lamp holder extends a support portion in annular seal space, and an end of positive terminal and anode connector all is embedded in the support portion, and the other end of positive terminal and anode connector all stretches out outside the support portion.
Preferably, heating wire is equally spaced winding insulator formation helical structure.
Preferably, helical structure lie low between positive terminal and anode connector.
Compared with prior art, because heating wire of the present utility model is wound on the insulator of mica material, and the insulator of mica material has the thermal resistance function of low loss, superior insulation function reaches cheaply advantage, so on the one hand so that heating bulb of the present utility model can improve efficiency to improve heat generation rate and can reduce waste of energy; Can reduce on the other hand the production cost of the utility model heating bulb.
Description of drawings
Fig. 1 is the plane structure chart of heating bulb one angle of the present utility model.
Fig. 2 is the plane structure chart of another angle of heating bulb of the present utility model.
Embodiment
In order to describe technology contents of the present utility model, structural feature in detail, below in conjunction with execution mode and cooperate accompanying drawing to be described further.
See also Fig. 1 and Fig. 2, the utility model heating bulb 100 comprises the insulator 40 of lamp holder 10, lamp housing 20, heating wire 30 and mica material.Lamp holder 10 is more excellent to be cylindrical shape so that the manufacturing of lamp holder 10, and lamp holder 10 is tightly connected with lamp housing 20 and forms an annular seal space 50, and simultaneously, lamp holder 10 has positive terminal 11 and the anode connector 12 that stretches in the annular seal space 50.Heating wire 30 and insulator 40 are built in the annular seal space 50, and an end of heating wire 30 and positive terminal 11 electric connections, and the other end of heating wire 30 twines insulator 40 and is electrically connected with anode connector 12, and is filled with inert gas in the annular seal space 50.Particularly, in the present embodiment, the inert gas of annular seal space 50 interior fillings can be single nitrogen, helium or argon gas etc., also can be the mist that is formed by nitrogen, helium and argon gas, the more excellent gaseous mixture that is formed by nitrogen and argon gas, the mixed proportion optimum of this nitrogen and argon gas is 3:7, and purpose is can extend to greatest extent the ordinary life of heating wire 30 and the normal operation of guaranteeing heating wire 30.Wherein, for ease of being connected of heating bulb 100 of the present utility model and extraneous lamp socket, so lamp holder 10 is provided with the helicitic texture 13 that is connected with extraneous lamp socket, this helicitic texture 13 is more excellent to be that external thread structure is so that the processing and manufacturing of the helicitic texture 13 on the lamp holder 10, certainly, according to actual needs aforesaid helicitic texture 13 is designed to female thread structure, so be not described in detail in this; For the ease of the processing and manufacturing of insulator 40, so insulator 40 structure in the form of sheets, more excellent is the rectangular laminated structure of insulator 40.More specifically, as follows:
Than the superior, insulator 40 is to be connected on positive terminal 11 and the anode connector 12, so that insulator 40 installing and fixing on annular seal space 50.
Simultaneously, lamp holder 10 extends a support portion 14 in annular seal space 50, and support portion 14 is more excellent to be the center that is positioned at annular seal space 50, so that support portion 14 designs are more reasonable, reduces the demand to annular seal space 50; And an end of positive terminal 11 and anode connector 12 all is embedded in the support portion 14, the other end of positive terminal 11 and anode connector 12 all stretches out outside the support portion 14, so that support portion 14 can provide secure support for positive terminal 11 and anode connector 12, prevent from being connected with positive terminal 11 and anode connector 12 plaies of insulator 40.
At last, heating wire 30 is equally spaced winding insulator 40 and forms helical structure, prolong the length that is wound in the heating wire 30 on the insulator 40 in the annular seal space 50, correspondingly increased the heating power of heating wire 30, thereby advanced the heating effect that a ground improves heating bulb 100 of the present utility model.Particularly, helical structure be lie low between positive terminal 11 and anode connector 12 so that the layout of the helical structure of heating wire 30 in annular seal space 50 is more reasonable, correspondingly reduce helical structure to the demand of annular seal space 50.
Compared with prior art, because heating wire 30 of the present utility model is wound on the insulator 40 of mica material, and the insulator 40 of mica material has the thermal resistance function of low loss, superior insulation function reaches cheaply advantage, so on the one hand so that heating bulb 1 00 of the present utility model can improve efficiency to improve heat generation rate and can reduce waste of energy; Can reduce on the other hand the production cost of the utility model heating bulb 100.
Above disclosed only is preferred embodiments of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim still belongs to the scope that the utility model is contained.
