Problems solved by technology

[0004] Existing fans generally include a housing in which an independent motor and blade assembly are fixed, and the motor motor is connected to the blade assembly through an output shaft. In this way, a fan is provided on the top of the motor motor so that it can be used in a limited housing volume. Inside, the size of the fan cannot be set too large, which reduces the efficiency of the fan for heat transfer
Secondly, the motor and the casing are generally connected by screws, the upper cover of the casing and the base are also connected by screws, and the whole fan is also connected by screws when installed on the seat, which makes it very inconvenient to install and disassemble.

Abstract

The invention relates to a fan for an automobile seat, which is used for dissipating heat or heating the automobile seat. A motor stator assembly of the fan is directly sleeved on a base middle pipe in a seat body and a fan blade assembly is sleeved on the motor stator assembly, so that the space is saved, blades of the fan blade assembly can be bigger under the condition of unchanged size of a shell, and the working efficiency is improved. Meanwhile, connecting pieces used in the assembling process of the shell, such as the fan blade assembly, a motor and the like, are also saved, the cost is saved, the assembly of the fan for the automobile seat can be implemented without a special tool, and the assembling and maintaining efficiency is improved.

Description

technical field [0001] The invention relates to a fan, in particular to a fan used for cooling or heating car seats. Background technique [0002] In order to solve the problem of poor air circulation in the car, drivers often add fans to the car. Customarily, the car fan is mainly directly fixed at an appropriate position in front of the driver's seat or above the seat by means of a pivot seat, and is supplied to the fan motor by connecting the conductive wires of the car or through a socket. [0003] However, when the weather is hot and hot, the driver and the seat contact still cannot avoid the situation of sweating, which causes the passenger to have a sense of discomfort. And this kind of discomfort can't be solved by the car fan in the past. In addition, because the car seat surface is often packed with a layer of leather or plastic packaging in winter, because the temperature is low, people will feel uncomfortable when they just sit on it. Feeling, and after sitting...
