Circulating fan

Abstract

A circulating fan includes a front cover, a rear cover, a fan module, an ultraviolet (UV) antibacterial purification module, and a cover plate. The rear cover includes a first surface remote from the front cover, a second surface opposite to the first surface, and an opening penetrating the first and second surfaces. The fan module is located between the front cover and the rear cover. The UV antibacterial purification module is located between the fan module and the rear cover. The cover plate covers the opening and is connected to the rear cover via a perforated design.

Claims

1. A circulating fan, comprising: One front cover; A rear cover includes a first surface remote from the front cover, a second surface opposite to the first surface, and an opening penetrating the first surface and the second surface; a fan module located between the front cover and the rear cover; an ultraviolet light antibacterial purification module located between the fan module and the rear cover; and a cover plate covering the opening and connected to the rear cover through a perforated stamp.

2. The circulating fan as claimed in claim 1, wherein the rear cover further includes a sidewall extending from the first surface around the edge of the opening and away from the first surface.

3. The circulating fan as described in claim 1, wherein the ultraviolet antibacterial purification module includes a body and two connectors, the body is annular, and the two connectors are disposed on opposite sides of the body, wherein the two connectors are respectively fixed to the second surface and located on opposite sides of the opening.

4. The circulating fan as described in claim 3, wherein the body has a light-emitting surface, the light-emitting surface having a light-reflecting channel, configured to uniformly project an ultraviolet light emitted by the ultraviolet antibacterial purification module.

5. The circulating fan as described in claim 3, wherein the ultraviolet antibacterial purification module provides ultraviolet light with a wavelength range covering one of 200 nanometers to 400 nanometers.

6. The circulating fan as claimed in claim 1, wherein the front cover includes an air outlet, wherein the air outlet, the fan module, and the ultraviolet antibacterial purification module are coaxial in one of the arrangement directions of the front cover and the rear cover.

7. The circulating fan as claimed in claim 1, wherein, in one of the arrangement directions of the front cover and the rear cover, the projection range of one of the fan modules covers the ultraviolet antibacterial purification module.

8. The circulating fan as described in claim 7, wherein one body of the ultraviolet antibacterial purification module has a light-emitting surface and a back surface opposite to the light-emitting surface, the light-emitting surface facing the fan module and the back surface facing the rear cover.

9. A circulating fan, comprising: One front cover; A rear cover includes a first surface remote from the front cover, a second surface opposite to the first surface, and an opening penetrating the first surface and the second surface; a fan module located between the front cover and the rear cover; an ultraviolet light antibacterial purification module located between the fan module and the rear cover; and a cover plate covering the opening, wherein the rear cover further includes a snap-fit ​​groove, and the cover plate has a snap-fit ​​element corresponding to the snap-fit ​​groove.

10. The circulating fan as claimed in claim 9, wherein the engaging slot has a first slot segment and a second slot segment connected together, the area of ​​the first slot segment being larger than the area of ​​the second slot segment.
