Abstract

An electronic device is directly disposed on a lamp base and is powered by the lamp base. The electronic device includes a connection base matching with a specification of the lamp base, and an air-flow generator. The connection base may be directly screwed into the lamp base to power the air-flow generator, so that the air-flow generator operates to generate an air flow.

Claims

1. An electronic device, disposed on a lamp base, the electronic device comprising:

a connection base, having a threaded connecting portion connected to the lamp base; and

an air-flow generator, disposed on the connection base, for generating an air flow,

wherein the threaded connecting portion has an accommodation space therein, the threaded connecting portion is formed with a through hole on one side thereof, an electrical connection post and an elastic element are disposed in the accommodation space, the electrical connection post is inserted in the through hole, and the elastic element is connected to one end of the electrical connection post, so as to force the electrical connection post to protrude out of the threaded connecting portion.

2. The electronic device according to claim 1, wherein the threaded connecting portion has a male thread, the lamp base has a female thread matching with the male thread therein, and the male thread is fitted with the female thread, such that the threaded connecting portion is connected to the lamp base.

3. The electronic device according to claim 1, wherein the air-flow generator is an axial-flow fan or a centrifugal fan.

5. The electronic device according to claim 1, wherein the air-flow generator further comprises a flow guide portion therein, and at least one vent corresponding to the flow guide portion is disposed on a side wall of the air-flow generator.

6. The electronic device according to claim 1, wherein the air-flow generator further comprises at least one damping washer therein.

4. (canceled)

7. An electronic device, disposed on an alternating current (AC) lamp base and used for generating an air flow, the electronic device comprising:

a connection base, having a threaded connecting portion and a rectifier, wherein the threaded connecting portion is connected to the AC lamp base, and the rectifier outputs a direct current (DC) power; and

an air-flow generator, disposed on the connection base and electrically connected to the rectifier, wherein the air-flow generator receives the DC power and generates an air flow,

wherein the threaded connecting portion has an accommodation space therein, the threaded connecting portion is formed with a through hole on one side thereof, an electrical connection post and an elastic element are disposed in the accommodation space, the electrical connection post is inserted in the through hole, and the elastic element is connected to one end of the electrical connection post, so as to force the electrical connection post to protrude out of the threaded connecting portion.

8. The electronic device according to claim 7, further comprising an anion generator disposed in the air-flow generator, wherein the anion generator is electrically connected to the rectifier to release a plurality of anions.

9. The electronic device according to claim 7, further comprising at least one light emitting diode (LED) disposed on the air-flow generator, wherein the LED is electrically connected to the rectifier to receive the DC power.

10. The electronic device according to claim 7, further comprising an ultraviolet lamp disposed on the air-flow generator, wherein the ultraviolet lamp is electrically connected to the rectifier to receive the DC power.

11. The electronic device according to claim 10, wherein the air-flow generator further comprises a photocatalyst screen and the photocatalyst screen is disposed opposite to a flowing direction of the air flow and corresponding to the ultraviolet lamp.

12. The electronic device according to claim 7, wherein the threaded connecting portion has a male thread, the AC lamp base has a female thread matching with the male thread therein, and the male thread is fitted with the female thread, such that the threaded connecting portion is connected to the AC lamp base.

13. The electronic device according to claim 7, wherein the air-flow generator is an axial-flow fan or a centrifugal fan.

15. The electronic device according to claim 7, wherein the air-flow generator further comprises a flow guide portion therein, and at least one vent corresponding to the flow guide portion is disposed on a side wall of the air-flow generator.

16. The electronic device according to claim 7, wherein the air-flow generator further comprises at least one damping washer therein.
