Fan with vibration function

Abstract

The invention discloses a fan with a vibration function. The fan comprises a drive mechanism, a fan component and a vibration mechanism, wherein the drive mechanism comprises a coil and a rotating shaft; the fan component and the vibration mechanism are coaxially assembled on the rotating shaft; the vibration mechanism comprises a ring-shaped rail and two roll balls; when the rotating shaft is driven by the coil to rotate in a positive direction, the two roll balls continuously rotate in the same direction close to and along with the rotating shaft to generate an eccentric torque to form vibration; the fan synchronously rotates along with the rotating shaft; otherwise, when the rotating shaft is driven by the coil to rotate in a negative direction, the roll balls roll along the ring-shaped rail until the two roll balls are separated mutually to form balance rotation, the vibration stops, the fan keeps rotating. With the adoption of the fan with the vibration function, a vibration mechanism is retrofitted on the fan, when the driving mechanism is in the positive direction and in the negative direction according to a mechanical principle, the difference of internal centroid positions is caused, so that the functions of heat dissipation and heat dissipation vibration can be realized controllably; when the drive mechanism is in the positive direction, a heat dissipation and vibration reminding function of the fan are realized; and when the drive mechanism is in the negative direction, and the function of the heat dissipation of the fan is realized.

Description

technical field [0001] The invention relates to a fan, in particular to a fan with a vibration function arranged on a mobile phone. Background technique [0002] At present, in the product design of mobile phones, the vibration reminder function has become the standard configuration of mobile phones. Therefore, the vibration driving mechanism has become an indispensable component in the mobile phone. [0003] At the same time, existing consumer electronic products such as mobile phones are getting smaller and smaller, but their performance is getting higher and higher, and the problem of heat dissipation is becoming more and more prominent. The traditional passive heat dissipation method has disadvantages such as high cost, poor heat dissipation effect, and complicated process. Therefore, a variety of miniature fans have emerged on the market, and choosing thin, light and small fans for active cooling is also the most economical and effective method. [0004] However, in c...
