Abstract

A breathing light assembly of an air purifier includes a front panel, a cover, a breathing light, a body cover, and a reflective strip. The cover includes a light transmission panel and a curved surface and is mounted to the front panel. The breathing light is mounted to the curved surface and faces the light transmission panel. The body cover cooperatively defines an optical channel with the cover. A surface of the body cover includes a light emitting zone within the optical channel. The light emitting zone faces the breathing light across the optical channel. Light emitted by the breathing light passes through the light transmission panel to the light emitting zone. The reflective strip is mounted on the light emitting zone and positioned at an end of the optical channel. The reflective strip reflects the light emitted by the breathing light.

Claims

1. A breathing light assembly of an air purifier, the breathing light assembly comprising:

a front panel;

a cover comprising a light transmission panel and a curved surface mounted to the front panel;

a breathing light mounted to the curved surface and facing the light transmission panel;

a body cover, the body and the cover cooperatively defining an optical channel; and

a reflective strip;

wherein;

a surface of the body cover comprises a light emitting zone within the optical channel, the light emitting zone facing the breathing light across the optical channel;

light emitted by the breathing light passes through the light transmission panel to the light emitting zone;

the reflective strip is mounted on the light emitting zone and positioned at an end of the optical channel; and

the reflective strip reflects the light emitted by the breathing light;

wherein;

the body cover comprises a touch portion and a rear panel;

the touch portion is located at a top of the body cover;

the rear panel is located opposite the light emitting zone;

a heat sink is mounted to the rear panel;

wherein;

the heat sink is a radiating fin;

the body cover transmits heat in the light emitting zone and the radiating fin disperses heat from the light emitting zone.

2. The breathing light assembly of claim 1, wherein:

a surface of the front panel is concavely recessed to coupled to the cover;

the curved surface is formed on the cover;

the breathing light is mounted to the curved surface with a space between the surface of the front panel and the curved surface.

3. The breathing light assembly of claim 1, wherein:

the breathing light emits light at an angle relative to a horizontal plane;

the breathing light is adapted to emit light of different colors according to air quality;

the light emitted by the breathing light is projected along the angle to the light emitting zone.

4. The breathing light assembly of claim 1, wherein:

the cover is mounted to an upper part of the front panel;

the light transmission panel of the cover is mounted to the curved surface and faces the breathing light.

5. The breathing light assembly of claim 4, wherein:

the light transmission panel has a curved shape conforming to a shape of the curved surface;

the light emitted by the breathing light passes through a curvature of the light transmission panel.

6. The breathing light assembly of claim 5, wherein:

the light transmission panel is milky white in color and made of acrylic.

7. The breathing light assembly of claim 1, wherein:

the light emitting zone is located on a bottom portion of the body cover within the optical channel;

the light emitting zone is a concavely curved surface;

the concavely curved surface focuses the light emitted by the breathing light.

8. The breathing light assembly of claim 1, wherein:

the reflective strip is mounted to a junction of the light emitting zone and a top of the body cover at the end of the optical channel.
