Description
Technical field
The utility model relates to a kind of heat gun, especially a kind of heat gun heater.
Background technology
As a kind of electric tool commonly used, along with the needs of industrial development, the power output of heat gun is increasing, and is also more and more higher to the requirement of the fail safe of heat gun and reliability simultaneously.And the core position in the heat gun---the improvement of heater part is the most key.As just having described a kind of heat gun fixture in the utility model patent that October 12 calendar year 2001, the disclosed patent No. was CN2538196, make the heating wire difficult drop-off of heat gun heater part, heat efficiency height with locating piece.But the heating wire in this patent is fully on locating piece, and locating piece to be plug-in card be connected on the pedestal.Variations in temperature is very big in the heater, in case difference variation causes the instability that contacts of locating piece and pedestal, just is easy to cause locating piece loosening, the consequence of bringing the heating wire short circuit even blowing.Simultaneously owing to rely on fixedly heating wire of locating piece fully; therefore the shape of locating piece can not be too little; certainly will make that like this weight of heat gun increases greatly; be unfavorable for the use of ordinary consumer; bigger locating piece has also caused being difficult in the total place thermel protection device, can't protect heater under condition of overhigh temperature.Existing heat gun heater also has the band thermel protection device, but these protective devices generally are the settings of similar fuse, fuse automatically when temperature is too high.Such protective device is disposable, can't reuse, and also will spend a large amount of energy in the time of replacing, uses inconvenient.
The utility model content
The purpose of this utility model provides a kind of heat gun heater, and described heater can increase the heat efficiency that improves heater under few situation greatly for whole heat gun weight, and heating wire is not easy to blow, and more difficultly damages because of other reasons.The thermel protection device automatic disconnection is protected whole system when temperature is too high, and thermal protection system can reuse, can be because of once just needing to change after the protection.
In order to solve the problems of the technologies described above, the utility model adopts a kind of heat gun heater of following technical scheme, comprises the coil holder of being made up of insulation board, and coil holder is provided with groove I, and it is thick also to be provided with front end between the insulation board of described coil holder, and the rear end is thin, is tapered locating piece.Also be provided with groove II on the locating piece, heating wire is on the groove I of coil holder and among the groove II of locating piece.
Preferably, described coil holder is provided with location hole, and the locator of fixed block is riveted on the coil holder by location hole.Can further guarantee the stability of fixed block like this.The position of locating piece can not be subjected to displacement yet when guaranteeing simultaneously to use under high-temperature condition yet.
Preferably, set groove II is a wedge shape on the described locating piece, and such groove II is the same with groove I shape on the coil holder, the convenient heating wire of installing.
Preferably, set groove II is half arc on the described locating piece, and such shape and heating wire can mate better.Improve the heat efficiency of heat gun.
Preferably, also being provided with bottom the described coil holder can reusable heat protection thermostat.Make circuit thermel protection device automatic disconnection when temperature is too high, whole system is protected, and thermal protection system can reuse, can be because of once just needing to change after the protection.And heat protection thermostat is arranged on the coil holder bottom, and variations in temperature is less, can accurately feel variations in temperature, and disconnects at reasonable time.
The utility model is owing to adopted above-mentioned front end thick, the rear end is thin, be tapered locating piece, not only saved material, the weight of whole air pressure gun is descended, made that simultaneously the heat conduction of whole heater is more smooth, especially when heat gun back hair-dryer is worked, hot blast flows more smooth and easy, and firing rate is fast, heat efficiency height.Cooling rate also increases when heater quits work.Locating piece is provided with groove II, heating wire is on the groove I of coil holder and among the groove II of locating piece, whole like this heat gun weight increases the heat efficiency that improves heater under few situation greatly, and heating wire is not easy to blow, and more difficultly damages because of other reasons.

Embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of heat gun heater of the utility model, the coil holder of being made up of insulation board 11 1 constitutes, coil holder 1 is provided with groove I12, also be provided with locating piece 3 between the insulation board 11 of described coil holder 1, locating piece 3 is fixed on the coil holder 1 by the mode in the groove 13 that is connected to insulation board 11 and is used for fixing mutually, also is provided with groove II31 on the locating piece 3, among the groove I12 of heating wire 2 on the coil holder 1 and among the groove II31 on the locating piece 3, at last will lead 5 welding go up and get final product.Wherein locating piece 3 front ends are thick, and the rear end is thin, is tapered.So not only saved material, the weight of whole air pressure gun is descended, the thin structure in the thick rear end of front end makes that the heat conduction of whole heater is more smooth simultaneously, and firing rate is fast, heat efficiency height, and cooling rate also increases when not using.Locating piece 3 is generally made with pottery.
Because when using generally is that the hot blast muzzle is downward, under the effect of high temperature and gravity, locating piece 3 can change the position unavoidably, may damage heating wire 2.Occur for fear of such situation, we also are provided with the through hole 14 of the locator 6 that is used to install heater fixed block 3 on coil holder 1.Locator 6 is provided with joint pin 62, is used to be riveted on coil holder 1.After installing, fixed block 3 just in time can be stuck on its baffle plate 61.So just can not be owing to causing fixed block 3 displacements under gravity or the action of high temperature.
And this heater is installed in when working in the heat gun, because the relation of locating piece 3, under the situation of the heating wire 2 that uses same power, can improve the heating efficiency of whole heater.Also make simultaneously the heating wire 2 and the contact area of coil holder 1 increase.When temperature is very high, a little less than heating wire 2 is highly brittle.The contact area that increases can make heating wire 2 be difficult for disconnecting.Under the situation of not using heat gun, the contact area of increase also make heat gun fall or the situation of accidental impact under heating wire 2 do not come to harm.
Under the situation of carrying out large-scale production, set groove II31 is a wedge shape on the locating piece 3.Such groove II31 is the same with groove I12 shape on the coil holder 1, and the convenient heating wire 2 of installing improves workpeople's operating efficiency.But when doing some processing requests than higher heat gun heater, set groove I32 is half arc on the locating piece 3, and such shape and heating wire 2 can mate better, have further improved the heat efficiency.
