Abstract

The invention belongs to the field of fans, and particularly relates to a driving circuit and a fan. The driving circuit is composed of independent components and a chip. The rotation speed of the fan is controlled in real time through a negative temperature coefficient thermo-sensitive resistor, and the rotation speed of the fan is increased or decreased along with rising and falling of the environmental temperature. When the environmental temperature drops from a high point to the point lower than the temperature for starting the fan, the fan is made to work for a certain time through an energy storage capacitor so as to further lower the temperature, so that the situations that due to the fact that the temperature for starting the fan rises and drops in a range, the fan is turned on and turned off suddenly and accordingly the fan is damaged are avoided. In addition, by touching a control circuit, a user can control the fan to work in real time through a switch button according to needs. Thus, noise is effectively lowered, the power utilization rate is increased and the service life of the fan is prolonged.

Description

technical field [0001] The invention belongs to the field of fans, in particular to a driving circuit and a fan. Background technique [0002] At present, fans are commonly used in daily work and daily life to dissipate heat to reduce summer heat. [0003] With the development of electronic technology, various electronic products have penetrated into various fields; because electronic devices will affect the electrical quality and service life of electronic devices due to high ambient temperature, in order to solve this problem, it is usually used in the external environment of electronic products Or a fan is installed inside the electronic product to dissipate heat to force cooling. [0004] The traditional fan is a single fixed speed fan. Although the circuit of the fan is simple, it has the following disadvantages: [0005] In order to ensure that the system can still dissipate heat reliably under the maximum power consumption or maximum temperature working condition, t...
