Description

Technical Field

[0002] The existing technology, Chinese patent 202320339656.0, describes a chassis for a floor fan and the floor fan itself. The chassis includes a chassis body and a charging interface. The chassis body has a first recess, and the inner bottom wall of the first recess has a first opening. The charging interface is located inside the chassis body and protrudes through the first opening. The charging interface is used to connect to an external power source to power the floor fan. This allows the floor fan to be powered by an adapter connected to a power outlet or by a power bank, improving its flexibility. Furthermore, placing the charging interface on the side of the first recess near the chassis body helps protect the charging interface to some extent, extending the lifespan of both the charging interface and the floor fan, thus ensuring the reliable operation of the floor fan. However, a problem exists: the fan motor is externally mounted, with the front exhaust shroud and rear intake shroud located at the front end of the motor. Utility Model Content
