Abstract

The utility model relates to a separable air outlet net cover which is essentially used for a heat wind gun for electronic industry, electrician industry, packing industry and laboratory production as well as maintenance. The middle position of the cover body has a lug boss and the edge of the cover body is provided with a bending folded edge. The separable air outlet net cover has the advantages of easy machining, convenient installation, and capability of fixing a heating element, as well as smooth wind flow and good isolation.

Description

A kind of separate type air outlet mesh

Technical field

The utility model relates to the heat gun of electronics, electrician, packaging industry and Laboratory Production, maintenance usefulness, the air outlet mesh of the heat gun of more specifically saying so.

Background technology

Heat gun development so far, its simple, convenient carrying is changeed heat, experimental ware drying etc. and is widely used carrying out collapsible tube backheat, object fusion, paint removal, shrink wrapping, softening sheet, liquid.Because be no fiery high temperature heating, safety in utilization further improves, the utilization scope is more and more wider, is subjected to people's welcome deeply.Traditional heat gun, the wind outlet unit of its heat gun discharge pipe and discharge pipe are one-body molded to process, simple in structure, is the form that most heat gun products adopt.But because discharge pipe inner wall smooth, there is not the Support Position, cause the heater element that is installed in the discharge pipe not rely on, meeting secundly during installation, the electric property that can make on the one hand heat gun particularly insulating coefficient reduces, on the other hand since heater element depart from the output that the center can stop hot blast and can cause hot blast heat inhomogeneous so that temperature control inaccurate.In addition, the boring ratio of air outlet is bigger, and pocket-handkerchief falls into easily, causes danger.Owing to be one-body molded, process also more complicated, be through stretching several times, the percent defective height causes the waste of resource.

Summary of the invention

The purpose of this utility model be provide in order to overcome above-mentioned the deficiencies in the prior art part a kind of handling ease, easy for installation, fixedly heater element, air-out is smooth and easy, isolation is good heat gun goes out wind apparatus.

Technical solution of the present utility model is on the basis of cover body, ventilation unit, is equipped with lug boss in the interposition of cover body, and there is crooked flanging at the edge of cover body.

Above-described lug boss is garden shape or polygonized structure, for inwardly or to outer lug.

Ventilation unit of the present utility model is circular port or diamond hole.

Lug boss of the present utility model and cover body are one-body molded or by being welded together.

The utility model has the advantages that handling ease, easy for installation, fixedly heater element, air-out is smooth and easy, isolation good.

Description of drawings

Fig. 1 is an organigram 1 of the present utility model;

Fig. 2 is an organigram 2 of the present utility model;

Fig. 3 is user mode figure of the present utility model;

Fig. 4 is a user mode exploded view of the present utility model;

Fig. 5 is the outline drawing of traditional heat gun discharge pipe.

The specific embodiment

Shown in Fig. 1,2, the utility model is on the basis of cover body 1, ventilation unit 3, and position has lug boss 2, edge that crooked flanging 4 is arranged in the middle of it.

Shown in Fig. 3,4, air outlet mesh of the present utility model is installed in the discharge pipe 5 near head position.

Operation principle of the present utility model is when heat gun is installed, air outlet mesh is installed in the discharge pipe 5, by flanging 4, increased contact-making surface with discharge pipe 5 inwalls, air outlet mesh more stably is fixed in the discharge pipe 5, when heater element is installed, heater element is installed in the discharge pipe 5, the hole that the head of heater element has the lug boss 2 with guard to adapt, heater element is fixed on the guard, by the support of guard, and heater element position relative fixed, in the heat gun use, heater element remains at the centre position in the discharge pipe, has improved the electric property of product, and the output of air quantity and the temperature of wind reach stable, heater element can arbitrarily not swung owing to fixing, has increased security.The wind of exporting in the heat gun, by the heating of the heater element in the discharge pipe 5, the ventilation unit 3 from air outlet mesh is sent.Because air outlet mesh and discharge pipe are processed respectively, reduced the difficulty of processing and to the requirement of process equipment, the yield rate raising has reduced production cost.

Claims

1, a kind of separate type air outlet mesh comprises cover body, ventilation unit, it is characterized in that the interposition of cover body is equipped with lug boss, and there is crooked flanging at the edge of cover body.

2, a kind of separate type air outlet mesh as claimed in claim 1 is characterized in that lug boss is garden shape or polygonized structure, for inwardly or to outer lug.

3, a kind of separate type air outlet mesh as claimed in claim 1 is characterized in that ventilation unit is circular port or diamond hole.
