Abstract

The present invention provides an airflow outlet of air-conditioning device, which comprises a main body having one end forming an entrance opening and an opposite end forming a plurality of outward-projecting curved ridges. At least one of the curved ridges has a side wall forming at least one through hole to allow air to pass through the through hole. The present invention allows airflows generated by an air-conditioning device to be conducted to the through hole to be discharged therefrom. Since the through hole is formed in a side wall, airflows do not blow directly down as that occurring in the conventional devices and instead blowing sideways so as to eliminate any potential risk of causing discomfort of persons located under the airflow outlet.

Claims

1. An airflow outlet of air-conditioning device, comprising:

a main body, which has one end forming an entrance opening and an opposite end forming a plurality of curved ridges, at least one of the curved ridges having a side wall in which at least one through hole is formed to allow airflow that enters the entrance opening to pass through the through hole.

2. The airflow outlet of air-conditioning device according to claim 1, wherein each of the curved ridges has a height that is gradually decreased from a center of the main body toward the outside.

3. The airflow outlet of air-conditioning device according to claim 1, wherein the curved ridges are arranged to be adjacent to each other.

4. The airflow outlet of air-conditioning device according to claim 1, wherein the main body further comprises an outward-projecting cup-like protrusion, the cup-like protrusion comprising a cup body and a bottom cover, the bottom cover being set on an end of the cup body, the cup body comprising at least one through hole.

5. The airflow outlet of air-conditioning device according to claim 4, wherein the bottom cover further comprises at least one airflow guide plate, a rotatable mechanism being coupled between the bottom cover and the cup body to allow the bottom cover to be rotatable with respect to the cup body.

6. The airflow outlet of air-conditioning device according to claim 5, wherein the cup body comprises an extendable structure to allow the cup body to selectively extend/retract.

7. The airflow outlet of air-conditioning device according to claim 6, wherein the extendable structure comprises:

at least one first cup body, which comprises a first upper cup opening and a first lower cup opening; and

at least one second cup body, which comprises a second upper cup opening and a second lower cup opening, wherein diameter of the second upper cup opening is greater than or equal to diameter of the first lower cup opening and diameter of the second lower cup opening is smaller than the diameter of the first lower cup opening, the bottom cover being set on the second lower cup opening.

8. The airflow outlet of air-conditioning device according to claim 7, wherein the curved ridges are arranged in a concentric form or a radiating form.

9. The airflow outlet of air-conditioning device according to claim 6, wherein the extendable structure comprises:

at least one first cup body, which comprises a first upper cup opening, a first lower cup opening, and a first internal retention strip, wherein the first internal retention strip is mounted to an inside surface of the first cup body; and

at least one second cup body, which comprises a second upper cup opening, a second lower cup opening, and a second external retention strip, wherein the second external retention strip is mounted to an outside surface of the second cup body and the bottom cover is set on the second lower cup opening;

wherein the second upper cup opening is received in the first cup body and is movable in the first cup body and the second external retention strip is arranged on the first internal retention strip.

10. The airflow outlet of air-conditioning device according to claim 9, wherein the curved ridges are arranged in a concentric form or a radiating form.
