Problems solved by technology

[0004] In order to solve the deficiencies of the prior art, the present invention provides a hollow-shaft booster fan. The primary technical problem to be solved is that the fan blades are easily collided with foreign objects, and accidental touch by human hands will cause danger. The secondary technical problem is the noise. Large, and the air volume is small, the supercharging effect is not obvious

Embodiment Construction

[0028] The invention is a hollow-shaft booster fan, which has the advantages of simple structure, good safety performance, large air output, stepless variable speed, and the like.

[0029] Such as Figure 1-Figure 6 , The hollow shaft booster fan of the present invention is mainly composed of three parts, namely a fixed part, a transmission part and an execution part.

[0030] The fixed part includes an inner shell 1 , a supporting structure 2 , an outer shell 3 and a fan base 4 sequentially from the inside to the outside.

[0031] The inner shell 1 is circular and includes two parts, the first inner shell and the second inner shell, which are made of injection molding material. The first inner shell and the second inner shell are respectively equipped with fan blade slide rails 11, and the fan blade slides as a whole It is circular, and the section of the circular ring is T-shaped. Finally, it is formed by connecting two inner casing reduction box nails and inner casing con...

Abstract

The invention discloses a hollow shaft supercharging fan. An inner shell and a ring-shaped outer shell are integrally connected through a supporting structure to form a ring-shaped air channel. Two ring-shaped fan blade sliding rails are arranged on the outer surface of the inner shell and are symmetrically arranged about the supporting structure, wherein the sections of the fan blade sliding rails are in a T shape. An executing part is composed of a first fan blade assembly and a second fan blade assembly, the first fan blade assembly and the second fan blade assembly are the same in structure and are symmetrically arranged on the two fan blade sliding rails about the supporting structure. Blade bodies on peripheral fan blades are obliquely arranged on the outer side of a ring, and the blade inclination direction in the second fan blade assembly is opposite to the blade inclination direction in the first fan blade assembly. A motor drives the first fan blade assembly and the second fan blade assembly to rotate in opposite directions through a transmission part. Hollow shaft design is adopted in the hollow shaft supercharging fan, sounds are lower due to the multiple fan blades, and the use comfort of the product is improved.

Description

technical field [0001] The invention relates to a booster fan, specifically a hollow shaft booster fan. Background technique [0002] A fan refers to an electric fan used to generate wind to keep cool in hot weather. It is a device driven by electricity to generate air flow. [0003] In the existing fans, although the fan blades are protected by a casing, but the fan blades are too large, they will inevitably be collided with foreign debris, and may even be accidentally touched by human hands and cause danger; Noise is generated, which brings some inconvenience to people's work or life; the air volume is too small, and the supercharging effect is not obvious. Contents of the invention [0004] In order to solve the deficiencies of the prior art, the present invention provides a hollow-shaft booster fan. The primary technical problem to be solved is that the fan blades are easily collided with foreign objects, and accidental touch by human hands will cause danger. The seco...
