Abstract

The invention discloses a hot air gun and belongs to the technical field of heating machinery. The hot air gun comprises a machine head and a machine body. The machine head comprises a machine head shell. A motor, a fan and a heating assembly are arranged in the machine head shell. The machine body comprises a machine body shell. The machine head shell is rotationally connected with the machine body shell. A locking mechanism used for fixing the machine head relative to the machine body is arranged between the machine head shell and the machine body shell. According to the hot air gun, the machine head and the machine body are arranged to be of a split structure, the machine head is rotationally connected with the machine body, and the locking mechanism is arranged between the machine head and the machine body, so that a user adjusts the angle between the machine body and the machine head according to using conditions and using requirements, and the universality and using convenience of the hot air gun are improved.

Description

technical field [0001] The invention relates to the technical field of heating machinery, in particular to a heat gun. Background technique [0002] A heat gun is a heating machine 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] A heat gun is generally composed of a shell, a motor placed in the shell, a fan, a heating element, a switch, and other components. The shell of an existing heat gun usually adopts a left-right symmetrical split structure, and screws or bolts are used to fix the shell when assembling. . After...
