A numerical control fan shell structure

Abstract

The invention discloses a novel numerically controlled fan shell structure, which belongs to the technical field of numerically controlled fans, and comprises a fan shell, a shell and a bottom plate. The upper surface of the bottom plate is fixedly connected with two shells, and there is a fixed connection between the two shells. The fan casing is provided with a fixed ring inside the fan casing, and positioning mechanisms are arranged on the left and right sides of the fixed ring, and the outer surface of the fan casing is provided with clamping holes corresponding to the positions of the two positioning mechanisms. In the present invention, by setting the air guide mechanism, the first air guide pipe and the second air guide pipe are arranged in the air guide mechanism, and the first air guide pipe can be adjusted to a certain angle in the second air guide pipe, so the smoke and dust can pass through the second air guide pipe. The first air guide pipe and the second air guide pipe are discharged at different angles. By setting the positioning mechanism, when the air guide mechanism is not needed, the positioning mechanism can be used to disassemble the air guide mechanism from the fan casing. At this time, the fan The wind force discharged from the shell can be discharged along the normal trajectory, which greatly improves the scope of application of the fan.

Description

technical field [0001] The invention belongs to the technical field of numerically controlled fans, and in particular relates to a shell structure of numerically controlled fans. Background technique [0002] Existing fans have airflow in the same direction as the axis of the fan blades, such as electric fans and air conditioner external fans are fans that operate in axial flow mode. The reason why it is called "axial flow" is because the gas flows parallel to the axis of the fan, Flow fans are usually used in occasions with high flow requirements and low pressure requirements, while CNC fans are connected to a CNC controller on the outside of the fan, and the controller is used to accurately control the wind force and working time of the fan. Compared with traditional fans, By improving its degree of automation, the CNC fan is more convenient to use. The Chinese patent discloses "a shell structure of an enhanced axial fan and an axial fan" (patent number: CN201920599295.7),...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problems in the prior art that the filter screen is difficult to disassemble, the wind force cannot be changed and the adjustment of the base affects the use of the fan, and a numerically controlled fan shell structure is proposed.
