Embodiment approach 1

[0019] Such as figure 1 As shown, the cover body with the support frame is installed on the heat gun, and the free edge 1 of the cover body is fixed by rivets 8 at least two arc-shaped metal support rings 2 arranged in parallel as the support frame. The metal support ring 2 does not block the air outlet of the heat gun. Such a structure ensures a distance of at least 1 centimeter between the free edge 1 of the cover body and the processing object, and usually this distance is preferably 3 centimeters. During the heating process, the radian of the metal support ring 2 can also be used to adjust the heating angle relatively labor-saving and accurately.

[0020] Such as figure 2 , image 3 As shown, the support frame is a bent metal ring, and the metal ring is bent into three parts: a fixed part 3, a transition part 4 and a support part 5, wherein the fixed part 3 and the free edge 1 of the cover have the same arc And fixed on the free edge 1, the support part 5 is away from...

Abstract

The invention aims at overcoming the defects in the prior art, and provides a cover body with support frames. The cover body can be used for electric tools such as a heat gun, on the premise that the heat efficiency is guaranteed, the problem that a heating object is overheated can be avoided, the overall operation is more convenient and rapid, and adverse effects cannot occur when the wind speed is adjusted. In order to achieve the purpose, the cover body with the support frames is used for the heat gun, and the support frames are installed on at least one of the inner side, the outer side and a free edge position of the cover body. By means of the cover body with the support frames, the problem that the whole heating object is overheated to be damaged due to the fact that a person covers the heating object with the cover body and forgets to remove the cover body can be avoided; in addition, when heating is conducted, the support frames can be used for reducing the hand strength, the working intensity is reduced, and the overall heating precision is more accurate.

Description

technical field [0001] The invention relates to an auxiliary device for an air gun, in particular to a cover body with a support frame. Background technique [0002] The heat gun is mainly a device that uses the hot air blown from the gun core of the heating resistance wire to heat the heating object. In order to improve the heating effect, a cover is usually provided on the air outlet of the heat gun to prevent heat from dissipating. However, sometimes due to improper operation, when the entire cover is covered on the heating object, the heating object may be damaged due to excessive temperature. It may even cause the heat gun itself to be damaged due to overheating. [0003] In order to solve this technical problem in the prior art, the technical solution adopted is similar to the patent No. 201210228409.X "A device, assembly and method for manual local weeding", which includes a biological Heater 4. A heat generator 4 comprising a fan and a heating resistor injects a ...
