Wind wheel and air blower applying wind wheel

Abstract

The invention discloses a wind wheel and an air blower applying the wind wheel. The wind wheel comprises a top panel provided with a plurality of wind blades and a bottom panel. The multiple wind blades protrude out of the lower end face of the top panel, and the multiple wind blades and the top panel are integrally formed through injection molding. The multiple wind blades are located between thetop panel and the bottom panel. An air inlet is formed in the middle of the bottom panel. An air flue is formed between every two adjacent wind blades. A connecting base connected with a motor shaftis arranged in the center of the top panel. A plurality of positioning columns protrude out of the end faces, connected with the bottom panel, of the wind blades. The bottom panel is provided with installing holes for the positioning columns to penetrate, and the wind blades and the bottom panel are fixed together through welding. The end faces of the wind blades are further provided with a plurality of first bosses. The bottom panel is provided with grooves matched with the first bosses. The first bosses are embedded in the grooves, the first bosses and the grooves are combined together through welding, welding points are reduced, and the problem about solder skips is reduced; and the welding precision is improved, welding is firm, and the problems that during wind wheel running, jumpingis great, and balance performance is poor are effectively solved.

Description

Technical field: [0001] The invention relates to a wind wheel and a blower for its application. Background technique: [0002] The existing wind wheel includes a top panel, a bottom panel, and several wind blades installed and connected between the top panel and the bottom panel. An air inlet is arranged in the middle of the bottom panel, and an air duct is formed between two adjacent wind blades. A cavity is formed on the inside of the top of the wind blade, and an air outlet is formed on the outside of the wind blade. A connecting seat connected to the motor shaft is arranged in the center of the top panel, and several auxiliary pieces uniformly distributed around the axial direction protrude from the edge of the top panel. Wind blades, auxiliary wind blades and several wind blades are distributed on both sides of the top panel, and one end surface of the wind blades is combined with the bottom panel by welding. Since the wind blades and the bottom panel are plane welded, ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a wind wheel and a blower for its application, which solves the problem in the prior art that due to the plane welding between the wind blade and the bottom panel, there are many welding points, and the welding leakage is prone to occur during welding, which leads to the problem of the wind blade and the bottom panel. Welding between the panels is not firm, so that the wind wheel jumps greatly during operation and the balance is poor
