Problems solved by technology

This limits the use of the base to create air holes to provide air for the operation of the heat gun
Also, the use of slidable wings results in a weak structure that is easily damaged during use
Also, the wings need to slide in grooves which tend to get clogged when using the aforementioned heat gun

Embodiment Construction

[0019] refer to figure 1 and figure 2 , the heat gun includes a tubular main body 2 . The channel 4 formed by the body 2 extends over the entire length of the body (see figure 2 ). A D-shaped handle 6 with a clip 8 is attached to the side of the main body. The handle, in particular the clamping portion, extends in a direction substantially perpendicular to the longitudinal axis 18 of the main body 2 .

[0020] The interior of the body 2 is provided with a motor 10 which, when activated, drives in rotation a fan 12 mounted on its spindle 14 in the channel 4 .

[0021] The front part of the body 2 is fitted with a metal tube nozzle 16 , the longitudinal axis 18 of which is substantially parallel and coaxial with the longitudinal axis of said channel 4 . A plastic sheath 20 surrounding part of the length of the nozzle 16 is installed on the front of the main body 2 . As shown in the figure, a gap 22 is formed between the sheath 20 and the nozzle 16 . The shroud 20 defines...

Abstract

A heat gun comprising: a body; a fan assembly located within the body to generate an air flow; a heating device located within the body which, when activated, heats air which flows over and / or through the heating device ; a nozzle mounted on the front of the body to direct the air flow from the body; wherein the fan assembly, when activated, blows air over the heating device and then through the nozzle; a base mounted on the rear of the body; and a handle connected to the body; wherein there is further provided a support mechanism mounted on the handle remote from the base which comprises at least one arm moveably mounted on the handle and which is capable of moving between a first retracted position and a second extended position and wherein, when the at least one arm, is in its extendedposition, is capable of co-operating with the base to form a platform upon which the heat gun can rest on a work surface whilst locating the nozzle remotely from the work surface.

Description

technical field [0001] The invention relates to a heat gun. Background technique [0002] A heat gun is a device that produces a stream of hot air for various purposes. A heat gun consists of a tubular body with a fan built into it. Air is sucked in from one end of the body by a fan, blown out the other end through nozzles after passing a heating element also provided in the body for heating the air passing over or in it. [0003] US3668370 and US4135080 disclose heat guns. [0004] Hot air is usually exhausted from the body through metal nozzles. The problem with this design is that the nozzle can get very hot. Therefore, when the operator is done using the heat gun, they should not simply place the heat gun on its side on the work surface, as the heat from the nozzle will damage the work surface, but should at least wait until the nozzle cools down. Therefore, the heat gun must be placed on a surface that can withstand the heat, or where damage is inconsequential. Ev...
