Abstract

The invention provides a fan, which belongs to the technical field of fan equipment. Its technical scheme is: a fan, comprising a fan casing and a fan body arranged inside the fan casing, characterized in that the fan casing includes an inner frame body and an outer frame body, and the fan The main body is arranged on the inner frame body; the outer frame body is arranged with several installation components; the installation components include a cylinder body, a combustion chamber is arranged in the cylinder body, and a combustion chamber is arranged in the combustion chamber to generate a large amount of gas The combustible material, one end of the cylinder close to the outer frame is provided with a cylindrical connecting piece, a sealed space is formed between the cylindrical connecting piece and the combustion chamber, the combustible material burns, the Under the action of gas, the column-shaped connecting piece can penetrate into the wall through the outer frame. The beneficial effects of the present invention are: the fan is easy to install and can avoid using a drill bit to make holes on the surface of the wall.

Description

technical field [0001] The invention relates to the technical field of fan equipment, in particular to a fan. Background technique [0002] The motor and blades of the axial flow fan are all in the shell, which is used for local ventilation. The ventilation effect is obvious and safe. It can be used in metallurgy, chemical light industry, food factories, office buildings, residences and other places that need ventilation. , stable and reliable, features a wide range of function options. However, the existing axial flow fans still have shortcomings in use. The shape of the axial flow fan is relatively simple. When installing the axial flow fan, it is necessary to drill holes on the surface of the wall with a drill bit, and then use a plurality of bolts to The axial flow fan is fixed, and the installation process is cumbersome and inconvenient to operate. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a fan that is easy to install and ...
