Embodiment Construction

[0029] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0030] A multi-stage compressed air high-speed air circulation fan. The present invention mainly provides the structure of the fan head. Its swing head structure, pitch angle adjustment structure, bracket and console part are similar to the prior art, and do not contain the innovation points of the invention.

[0031] The fan head part includes a cover, an air inlet, a motor and an air outlet, and a spiral drainage mechanism is also designed at the air outlet.

[0032] The outer cover is divided into two parts, one part is the speed-increasing part of the air intake, between the air inlet and the drive wheel of the final blade; the other part is the air outlet directivity adjustment part, which is a wind tunnel structure formed by an outer cover composed of.

[0033] After the air inlet, it is divided into multi-stage air compression chambers. From the ...

Abstract

A multi-stage pneumatic high-speed air circulation fan adopts an air compressor structure similar to an aeroengine, and multiple layers of blades at different rotation speeds are used for driving to gradually increase the speed and pressure of inlet air in a multi-stage air compression cavity until the air speed and pressure are very high, so that the air can be diffused directionally. The multi-stage pneumatic high-speed air circulation fan can provide stronger air force, the air supply distance is farther than that of an existing air circulation fan, and better circulation and convection ofindoor air can be realized.

Description

technical field [0001] The invention relates to a household appliance, in particular to a multi-stage compressed air high-speed air circulation fan. Background technique [0002] Circulation fan is a popular fan design in recent years. It adopts a higher-speed air supply system and increases the air duct design, making the air supply distance longer than that of traditional household fans, and the wind force is more concentrated. [0003] Its role has also changed from the traditional household fan blowing directly on people to forming an air convection circulation system in an indoor closed environment, especially when combined with the air conditioner cooling system, it will greatly increase the cooling air supply distance of the air conditioner and speed up the improvement of the indoor environment. Air convection makes people feel comfortable and cool. [0004] However, the current design of the circulating fan is still the traditional fan motor system. It has been impr...
