Abstract

The invention provides a fan. The fan comprises a machine shell, a fan body, a transmission shaft, a motor and a monitoring system, wherein the fan body, the transmission shaft, the motor and the monitoring system are all positioned in the machine shell, the fan is connected with the machine shell through the transmission shaft, and the motor is connected with the transmission shaft through a belt; a shutter is arranged on one side, away from the transmission shaft, of the shell; the monitoring system comprises a detection unit, a control unit and a shutter adjusting unit; the shutter adjusting unit is connected with the shutter; the detection unit is used for detecting indoor environment information and / or the rotating speed of the motor; the control unit is used for generating a first control signal according to the environment information and / or the rotating speed of the motor; and the shutter adjusting unit is used for adjusting the working state of blades of the shutter accordingto the first control signal. According to the fan, through the indoor environment information and / or the rotating speed of the motor, the working state of the blades of the shutter is controlled, so that the fan is more intelligent, and the usability of the fan is effectively improved.

Description

technical field [0001] The invention relates to the technical field of ventilation equipment, in particular to a fan. Background technique [0002] The fan is a device for transporting gas. There are fans of various shapes and principles in the prior art. In order to protect the fans, motors and other components inside the fan, and not affect the normal use of the fan, it is usually placed on the side of the fan facing the outside. The shutters are set, and when the fan needs to exhaust air, only the blades of the shutters need to be opened to achieve ventilation. The fan in the prior art is driven by a motor to generate blowing air when the fan rotates, and the blowing blows the blades of the blinds to realize the opening of the blinds blades. This makes the blades of the blinds must be opened when the motor is working, and the opening angle of the blades depends entirely on Due to the wind force generated by the fan, that is, the working state of the louver blades on the ...
