Abstract
The utility model discloses a heating assembly for hot air guns. The heating assembly comprises a bracket and an electrical heating wire wound on the bracket. The bracket is formed by splicing a plurality of mica plates. The heating assembly also comprises a plurality of ceramic strips axially extending along the bracket, and each ceramic strip is arranged in the space enclosed by adjacent mica plates and the electrical heating wire. The number of the mica plates is optimally four to six, and the bracket formed by splicing the mica plates is a bracket of four to six angles. Grooves of which the size and shape fit with the electrical heating wire are arranged on the ceramic strips in the long directions. When the heating assembly is used, the thermal efficiency is high, and the electrical heating wire has small temperature difference and can not be easily fused. The heating assembly is suitable for being popularized and used in hot air guns.
Description
Technical field
The utility model relates to a kind of heat gun, especially relates to the heat generating component in the heat gun.
Background technology
Existing heat gun heat generating component is 03221194.5 as the patent No. of the applicant's previous application, and name is called the disclosed structure of heat gun heater, and it comprises support and the heating wire of winding on this support that is spliced to form by micarex.Though the heat generating component of this structure can make heating wire not yieldingly walk about, bump a short circuit in when work, but it is when work, also there are some shortcomings, promptly owing to partly in the space that adjacent micarex and heating wire surrounded, flow out than cold air, partly after the heating wire heating, flow out and have only than cold air, thereby the air discharge that heated through heating wire is less, cause the air-out of this heat generating component bigger in the different parts temperature contrast, and after the long period used, heating wire was also can Yin Wendu higher and fusing takes place damage phenomenon.
The utility model content
The technical problems to be solved in the utility model provides the heat gun heat generating component that a kind of temperature contrast is less, heating wire is difficult for fusing.
For solving the problems of the technologies described above, the utility model adopts so a kind of heat gun heat generating component, comprise the support and the heating wire of winding on this support that are spliced to form by some killinite plates, this heat generating component also comprises several along the axially extended ceramic bar of described support, and each ceramic bar is arranged in the space that is surrounded by adjacent micarex and heating wire.
Described micarex is preferably four to six, the described support that is spliced to form by micarex be four jiaos to the hexagon support.
After adopting such structure, owing to comprise that also several are along the axially extended ceramic bar of described support in the heat generating component, and each ceramic bar is arranged in the space that is surrounded by adjacent micarex and heating wire, thereby when work, can't in the space that adjacent micarex and heating wire surrounded, flow out than cold air, and must be through flowing out after the heating wire heating, improved the utilization rate of heating wire heat energy so on the one hand greatly, improved the thermal efficiency of heat generating component, what flow on the other hand also greatly reduces the temperature of heating wire than cold air, and make its temperature contrast less, even heating wire also is difficult for fusing when working long hours.
As a kind of preferred implementation of the present utility model, described ceramic bar also is provided with size, shape and the suitable groove of described heating wire on its length direction.After adopting such structure, heating wire can be entrenched in the groove of described ceramic bar, and so ceramic bar has played the fixed bearing effect to heating wire, thereby can prevent better that heating wire is out of shape the generation of walking about, bumping phenomenons such as a short circuit when work.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is a kind of structural representation of the utility model heat gun heat generating component.
Fig. 2 is the schematic top plan view of Fig. 1, does not wherein show ceramic bar.
Fig. 3 is the schematic top plan view of Fig. 1.
Fig. 4 is a kind of structural representation of ceramic bar in the utility model.
The specific embodiment
Referring to a kind of heat gun heat generating component shown in Fig. 1 to 4, comprise the support and the heating wire 2 of winding on this support that are spliced to form by some killinite plates 1, this heat generating component also comprises several along the axially extended ceramic bar 3 of described support, and each ceramic bar 3 is arranged in the space 4 that is surrounded by adjacent micarex 1 and heating wire 2.
Described micarex 1 is preferably four to six, and the described support that is spliced to form by micarex 1 shown in Figure 1 is the hexagon support.Certainly, described micarex 1 also can be more than six, and the described support that is spliced to form by micarex 1 also can be tetragonal support or is the support of shape such as hexagon.
As shown in Figure 4, described ceramic bar 3 is provided with the suitable groove 3-1 of size, shape and described heating wire 2 on its length direction.So when mounted, heating wire 2 can be entrenched in the groove 3-1 of described ceramic bar 3, and 3 pairs of heating wire 2 of ceramic bar have played the fixed bearing effect, thereby can prevent better that when work heating wire 2 is out of shape the generation of walking about, bumping phenomenons such as a short circuit.
The utility model is through on probation, and its air heat is rapid, and caloric value is big, and thermal efficiency height, and the difficult fusing of heating wire have been obtained good effect.
