Liftable fan based on stainless steel impeller

Abstract

The invention discloses a liftable fan based on a stainless steel impeller. The liftable fan comprises a housing, an impeller and a motor, wherein the motor is connected with the impeller; the impeller is limited in an inner cavity of the housing; an air inlet and an air outlet are formed in the housing; lifting type supporting legs are arranged on the bottom of the housing and the bottom of the motor; and each lifting type supporting leg comprises a straight barrel, a lengthened supporting rod, a supporting block and a supporting spring. A first filter screen assembly is further arranged between the impeller and the air inlet. The liftable fan has the advantages of being good in supporting stability and high in cleanliness of air discharged from the air outlet.

Description

technical field [0001] The invention relates to the technical field of impeller application, in particular to a liftable fan based on a stainless steel impeller. Background technique [0002] The impeller refers to the disc equipped with moving blades, including closed impeller, front semi-open impeller, rear semi-open impeller, open impeller and other forms. The impellers in the prior art are mostly used in technical fields such as liquid pumps or fans. [0003] When it is used in a liquid pump, the motor rotates to drive the impeller to rotate, and its high-speed rotation causes the liquid to generate centrifugal force, so that a vacuum is generated in the middle of the impeller, and the liquid is continuously sucked into the impeller to increase the kinetic energy of the liquid and play a driving role. When it is applied in the fan, similarly, its rotation generates centrifugal force, throws the air out of the impeller, collects it in the housing to increase the pressure...

AI Technical Summary

Problems solved by technology

It can be seen from this that when the invention is actually working, its stress point is concentrated on the connecting piece, and the connecting piece of the present invention is a movable piece. In this case, the connecting parts will be displaced, which will affect the overall stability of the device, and the shock absorption effect will be poor.

[0008] The existing suction fan has a weak ability to deal with the inhaled particulate matter or may bring new pollution. For example, a flue gas dust removal device with high efficiency dust removal and water saving proposed in patent application 201620330714.3 includes a device body, a settling box and The water pump and the first dust removal room and the second dust removal room are arranged in the device body, the smoke inlet is fixed on one side of the first dust removal room, the nozzle is fixed on the top of the first dust removal room, and the second dust removal room is fixed There is a filter screen, a vent is fixed between the first dust removal chamber and the second dust removal chamber, the bottom of the device body is fixed with a water outlet, the bottom of the water outlet is fixedly connected to the sedimentation tank, and one side of the sedimentation tank is fixed with a Suction pump, the water pump is fixedly connected to the nozzle through the water delivery pipe, and the top of the device body is fixed with a suction fan

This solution has the following problems: (1) The suction fan directly inhales particles, and the particles will cause damage to the blades of the suction fan and reduce the life of the suction fan; (2) The device described in this case has a large volume and high cost, and is suitable for large factories, etc. Large occasions are not suitable for small occasions: such as home use
