Embodiment 1

[0049] Such as Figures 1 to 15 As shown, the present invention provides a multifunctional heat gun, comprising a head 1 and a handle assembly, the head 1 is provided with a hot air device for generating hot air and a hot air pipe 8 for discharging the hot air generated by the hot air device, and the hot air pipe 8 is a metal pipe, specifically a stainless steel hot air pipe. The heat resistance of the stainless steel hot air pipe is good, which improves the durability of the hot air pipe and strengthens the strength of the hot air pipe. If the hot air gun is accidentally dropped during operation, It will not cause problems such as deformation and damage of the hot air pipe, wherein the handle assembly includes a handle 2 and an extension rod 3 detachably connected to the handle, the extension rod includes a connecting part 31 and a handshake part 32, the handle 2 is connected to the machine head 1 Relatively rotatable, the heat gun also includes a detachable battery pack 4, t...

Embodiment 2

[0089] The difference between this embodiment and the first embodiment lies in that the structure of the mounting bracket is different.

[0090] In this example, if Figure 16 As shown, the longitudinal section of the mounting bracket 91 is Y-shaped. Correspondingly, there are three closely wound sections 921 and are distributed at the three inner corners of the mounting bracket 91. In this way, the closely wound sections can also be separated, so that It does not affect the work between the closely wound sections, but also ensures that the heat between the closely wound sections is concentrated together and is not easy to disperse, so as to ensure that the temperature of the air outlet is sufficient to ensure the working effect of the heat gun, and Improve the working efficiency of the heat gun.

[0091] The structures and beneficial effects of other parts not described are the same as those in Embodiment 1, and will not be repeated here.

Embodiment 3

[0093] The difference between this embodiment and the first embodiment lies in that the structure of the mounting bracket is different.

[0094] In this example, if Figure 17 As shown, the longitudinal section of the mounting bracket 91 is Correspondingly, there are six closely wound sections 921 and they are distributed at the six inner corners of the mounting bracket 91. In this way, the closely wound sections can also be separated, so that it does not affect the connection between the closely wound sections. Working, it can also ensure that the heat between the closely wound sections is concentrated and not easy to disperse, so as to ensure that the temperature of the air outlet is sufficient to ensure the working effect of the heat gun and improve the working efficiency of the heat gun.

[0095] The structures and beneficial effects of other parts not described are the same as those in Embodiment 1, and will not be repeated here.

Abstract

The invention provides a multi-functional hot air gun. The multi-functional hot air gun includes a machine head and a handle assembly; a hot air device for generating the hot air is arranged in the machine head, the handle assembly comprises a handle and an extension rod detachably connected to the handle, the handle is connected to the machine head and can be rotated relatively, and the hot air gun further includes a detachable battery pack; and the battery pack is electrically connected with the hot air device and supplies the power to the hot air device so as to enable the hot air device towork, and the handle is connected with the machine head and can be rotated relatively, in this way, a user can operate conveniently in different use environments; when the direction of the hot air blowing out of the machine had is coincide or parallel or approaching parallel to the axis of the handle, the hot air gun can be used as a carbon igniting machine and can be used as a lawn mower with the extension rod; and when the direction of the hot air blowing out of the machine head intersects with the axis of the handle or is located on one side of the handle, the hot air gun can be used for the conventional hot air operation such as plastic product melting for melting connecting.

Description

technical field [0001] The invention relates to the field of electric tools, in particular to a multifunctional heat gun. Background technique [0002] A heat gun is a heating tool used to heat air to form a hot air flow. It has a variety of functions. Specifically, a heat gun can be used to remove old paint on metal surfaces, remove self-adhesive stickers, heat plastic hoses to bend them, Drying wet wood, heating shrinkage of packaging film and packaging tube, rust removal, heating shrinkage of polyethylene used to connect metals and heating softening of welds, etc., can also use the hot air blown from the gun core of the heating resistance wire Solder or remove components. [0003] The above-mentioned heat gun has a single function and can only be used to melt plastic products for welding, etc. As for the application of charcoal burning, weeding, etc., there is no targeted design, so it is inconvenient to use, and it is all connected to the power supply through the power ...
