Abstract

A fan integrated with a sensor is provided and includes a transmission terminal, a frame, a stator, a rotor with the blades. The transmission terminal is electrically connected to the sensor. The frame includes a main body and a supporting structure. The main body forms an inlet, and the supporting structure extends from the main body toward the interior of the inlet and embeds a part of the transmission terminal. Also, a method for manufacturing the above-mentioned fan is disclosed.

Claims

1. A fan integrated with a sensor, comprising:

a transmission terminal, electrically connected to the sensor;

a frame, comprising;

a main body comprising an inlet; and

a supporting structure, extending from the main body toward the inlet and embedding a part of the transmission terminal; and

a stator and a rotor with a plurality of blades disposed in the frame;

wherein the sensor is located close to the inlet.

2. The fan of claim 1, wherein the main body is constituted by an upper main body and a lower main body, and the inlet is disposed at the upper main body.

3. The fan of claim 2, wherein the supporting structure and the upper main body of the frame are integrally formed or molded as a single piece.

4. The fan of claim 1, wherein the sensor is a temperature sensor and/or a humidity sensor.

5. The fan of claim 1, wherein the sensor is a surface mount device (SMD).

6. The fan of claim 1, wherein the transmission terminal comprises a transmission portion and a carrier portion connected thereto, and the carrier portion is flat for holding and being electrically connected to the sensor.

7. The fan of claim 6, wherein the carrier portion comprises a first leadwire supporting sub-portion and a second leadwire supporting sub-portion extending and protruding inwardly and radically from two sites of the main body with an angle therebetween.

8. The fan of claim 6, wherein the carrier portion comprises a U-shaped or hollow rectangular cross section.

9. The fan of claim 6, further comprising a connection portion disposed on a peripheral of the frame, wherein the connection portion comprises at least two pins electrically connected to the sensor through the transmission portion of the transmission terminal, and a signal from the sensor is transmitted through the connection portion to an external system.

10. A method for manufacturing a fan, comprising:

providing a mold;

disposing the transmission terminal in the mold;

forming a frame with a supporting structure embedding a part of the transmission terminal by using the mold;

providing a sensor; and

electrically connecting the sensor with the transmission terminal.

11. The method of claim 10, wherein the sensor is a temperature sensor and/or a humidity sensor.

12. The method of claim 10, wherein the sensor is a surface mount device.

13. The method of claim 10, wherein the transmission terminal comprises a transmission portion and a carrier portion, and the carrier portion is flat for holding and being electrically connected to the sensor.

14. The method of claim 10, wherein the sensor is connected to the carrier portion by welding.

15. The method of claim 13, further comprising a connection portion disposed on a peripheral of the frame.

16. The method of claim 15, wherein the connection portion comprises at least two pins electrically connected to the transmission terminal, and a signal from the sensor is transmitted through the connection portion to an external system.

17. The method of claim 10, wherein the frame is formed by injection molding, hot melt molding, or compression molding.

18. The method of claim 10, wherein the frame and the supporting structure comprise resin.

19. The method of claim 10, wherein the frame further comprises a main body which is constituted by an upper main body and a lower main body, and the upper main body and the supporting structure of the frame are integrally formed as a single piece.

20. The method of claim 19, wherein the upper main body and the lower main body are combined by buckling.
