Portable fan blade mounting seat

Abstract

The present invention relates to the technical field of portable fans, in particular to a portable fan blade mounting seat; it includes a casing and four blade mounting pieces; the four blade mounting pieces are evenly distributed around All are inclined downward; the shell is a hollow cylinder; it also includes four motor blades, motor shaft mounts, motor shaft holes, and grille plates; the four motor blades are evenly distributed on the periphery of the motor shaft mounts , one end of the motor fan blade is bonded to the outer wall of the motor shaft mounting seat, and the other end is bonded to the inner wall of the casing; the middle part of the motor shaft mounting seat is provided with a motor shaft hole; the grille plate covers the surface of the motor fan blade, and the grille plate The outer ring of the grid plate is bonded to the inner wall of the housing, and the inner ring of the grid plate is bonded to the outer wall of the motor shaft mounting seat; the fan blade of the motor is inclined downward, and the direction of inclination is opposite to that of the fan blade mounting piece; A portable fan blade installation seat is invented, which can promote the air flow near the motor and protect the motor from heat dissipation.

Description

technical field [0001] The invention relates to the technical field of portable fans, in particular to a portable fan blade installation seat. Background technique [0002] Fan refers to a device used to generate wind to keep cool in hot weather. The electric fan is a device driven by electricity to generate air flow. The fan inside is energized and then rotates into natural wind to achieve the effect of enjoying the cool. In people's life, a lot of portable fans are widely used, and portable fan power is little, and is easy to carry, and wind direction is adjustable, is widely liked by people. The portable fan uses a motor to drive the fan blade mounting seat to rotate, and the fan blade mounting seat drives the inclined blade to blow the wind forward; but the air flow in the center behind the fan blade is poor, and the motor is located directly behind the fan blade mounting seat. It is difficult to dissipate the heat quickly, which will cause the motor to heat up, reduce...

AI Technical Summary

Problems solved by technology

The portable fan uses a motor to drive the fan blade mounting seat to rotate, and the fan blade mounting seat drives the inclined blade to blow the wind forward; but the air flow in the center behind the fan blade is poor, and the motor is located directly behind the fan blade mounting seat. The heat is difficult to dissipate quickly, causing the motor to heat up, reducing the service life of the motor, and causing the motor to burn out when overheating
