Description

Technical Field

[0001] This utility model relates to a tower fan. Background Technology

[0002] The existing technology, Chinese Patent 202022817120.4, discloses a snap-fit ​​building fan, including a shell, a fan body, a top cover assembly, and a base. The shell, top cover assembly, and base are assembled together to form an installation cavity. The fan body is disposed within the installation cavity. The shell includes a front shell and a rear shell that are assembled together, and the front shell and the rear shell are assembled by a snap-fit ​​device. The snap-fit ​​device includes a lower snap fastener and an upper snap-fit ​​body that are snapped together. The upper snap-fit ​​body is provided on the inner side wall of the front shell, and the lower snap fastener is provided on the inner side wall of the rear shell. The lower snap fastener is snapped onto the upper snap-fit ​​body from bottom to top.
