Description

Heat gun heat generating component

Technical field

The utility model relates to a kind of heat gun, it is specifically related to used heat generating component in heat gun.

Background technique

Existing heat gun heat generating component, including splicing the bracket formed by several killinite plates, being wound around on bracket Heating wire and the porcelain item being arranged in adjacent micarex and the surrounded space of heating wire；On the lateral surface of porcelain item along its length Offer several spaced apart grooves for heating wire insertion along its length equipped with the raised line outwardly protruded, on raised line, The lateral surface of porcelain item is outer convex arc surface, and the medial surface of porcelain item is interior concaved circular cambered surface.

But there is the shortcomings that following three aspects in the heat generating component of this structure in use: on the one hand, due to The lateral surface of porcelain item is outer convex arc surface, and heating wire is tightly attached to during installation on the lateral surface of porcelain item, therefore the ventilation of heating wire Heat dissipation effect is poor, and heating wire easily occurs hot-spot and fuses；Porcelain item itself has higher when on the other hand, due to work Heat, and heating wire is tightly attached on porcelain lateral surface, porcelain item by its heat transfer to heating wire, so as to cause heating wire part Temperature further increases and is easier to occur fusing accident, affects the service life of heat generating component；In another aspect, due to porcelain item Medial surface is interior concaved circular cambered surface, causes draught area small, is unfavorable for radiating, therefore affects the service life of heat generating component.

Summary of the invention

The technical problem to be solved by the present invention is to provide a kind of result of ventilating heat dissipation that can effectively improve heating wire, greatly Width extends the service life of heat generating component, and structure is simple, the low heat gun heat generating component of manufacturing cost.

In order to solve the above technical problems, the utility model uses such a heat gun heat generating component, including by several pieces Bracket, winding heating wire on the bracket and the setting of insulation board splicing composition are enclosed in adjacent insulation board and heating wire At the porcelain item in space；A raised line outwardly protruded is equipped on the lateral surface of the porcelain item along its length, on the raised line Several spaced apart grooves for heating wire insertion are offered along its length, and the lateral surface of the porcelain item is flat Face, shape or square or acute angle shape in obtuse angle between the lateral surface of the porcelain item and the side of raised line.

As a kind of preferred embodiment of the utility model, the medial surface of the porcelain item is plane, the porcelain item it is interior Cross section ventilation slot triangular in shape is formed between side and adjacent insulation board.

In the present invention, the insulation board preferably has four pieces, four pieces of insulation boards splicing, one cross of composition Bracket, the porcelain item and triangle ventilation slot it is equal there are four.

It in the present invention, is preferably in 90 ° of α≤120 ° < between the lateral surface of the porcelain item and the side of raised line Obtuse angle shape is in 60 °≤α <, 90 ° of acute angle shapes.

After adopting the above structure, the utility model has the following beneficial effects:

Since the lateral surface of the utility model porcelain item is plane, shape in obtuse angle between the lateral surface of porcelain item and the side of raised line Either square or acute angle shape, therefore, heating wire are not in contact with the lateral surface of porcelain item during installation and far from lateral surface, electricity There is the cooling air channel for the ventilation and heat that is highly advantageous between heated filament and the lateral surface of porcelain item, effectively prevent heating wire hot-spot And fusing accident occurs.

Since heating wire is not in contact with the lateral surface of porcelain item, the heat of porcelain item itself is not transferred to when work Heating wire effectively prevents heating wire part and further overheats and fusing accident occurs.

Since the medial surface of the utility model porcelain item is plane, formed between the medial surface of porcelain item and adjacent insulation board transversal Face ventilation slot triangular in shape, therefore, the draught area between porcelain medial surface and insulation board is bigger compared with the prior art, more favorably In heat dissipation, the service life of heat generating component is further extended.

The utility model structure is simple, is easy to implement, and manufacturing cost is low, long service life.
