Gesture control method and device for vehicle mounted atomizer

A gesture control method for a vehicle mounted atomizer, wherein the vehicle mounted atomizer comprises a light emitting component fixedly installed on a front of the vehicle mounted atomizer and a position sensor, wherein, the light emitting component is configured to actively emit infrared ray having a constant angle, and the position sensor is configured to receive the infrared ray, wherein the gesture control method comprises:

• calculating a real-time distance between the light emitting component and an obstacle according to an incident angle of received infrared ray;
• presetting a distance threshold, generating a first control command in a condition that the real-time distance is less than the distance threshold, triggering a connection or disconnection of a switch unit by the first control command, coupling an atomization piece of the vehicle mounted atomizer with a power supply unit via the switch unit, detecting a current on/off state of the switch unit, and generating a corresponding voice prompt according to the on/off state;
• wherein the gesture control method for a vehicle mounted atomizer further comprises:
• causing the vehicle mounted atomizer to enter a switch control stage in a condition that a first preset time is passed and a connection of the switch unit is triggered by the first control command;
• triggering a disconnection of the switch unit by the first control command after the first preset time;
• causing the vehicle mounted atomizer to be in an atomization amount control stage during the first preset time and after the connection of the switch unit is triggered by the first control command;
• detecting and accumulating a generation time of the first control command during the first preset time;
• and
• generating a second control command according to a mapping relationship of the generation time;
• wherein, the second control command triggers the switch unit to turn on or off according to a preset PWM pulse width.
