Fan

Abstract

The invention provides a fan. The problem that the assembly of a fan in the prior art is time-wasting and inconvenient is solved. The fan includes a motor, two frames, an impeller and a housing assembly. The two frames are coupled with an outer periphery of the motor and are engaged with each other by way of fastening. Each of the two frames includes one groove. The impeller is connected to the motor and is driven to rotate by the motor. The housing assembly houses the impeller and includes first and second housing parts. The first and second housing parts are engaged with each other by way of fastening. A protruding lip is provided on one of two end faces of the first housing part which is relatively adjacent to the motor. Another protruding lip is provided on one of two end faces of the second housing part which is relatively adjacent to the motor. The protruding lip and the other protruding lip are engaged with the grooves of the two frames.

Description

technical field [0001] The invention relates to a fan, in particular to a fan which can improve the convenience of assembly. Background technique [0002] Generally, at the entrances and exits of supermarkets or department stores, in order to block the outflow of indoor air-conditioning, or prevent outdoor foreign objects (such as mosquitoes, flies, insects, etc.) The air curtain device of the fan; the airflow blown down by it can form an air wall between the inside and outside of the door. On the one hand, it can prevent the cold air from leaking out of the room, and on the other hand, it can also block the outside dirty air or dust from entering. indoor. [0003] The existing fan has a motor frame, an impeller set and a casing. A motor is arranged inside the motor frame; the impeller set is connected to the motor and is driven to rotate by the motor; an accommodation space is formed in the casing, the accommodating space is provided for the impeller set, and the casing h...

AI Technical Summary

Problems solved by technology

[0004] However, the motor frame, the impeller set, and the casing of the existing fan are combined and positioned by locking components such as a plurality of screws; therefore, when assembling or disassembling the fan, personnel need to align the holes of each part one by one, Screwing and fixing with locking components is a very time-consuming and labor-intensive process. Since it is completely dependent on manual operations, not only the entire assembly and combination process is cumbersome and inconvenient, but also increases the operating cost, which in turn affects the overall operating efficiency.
