The diffuser cone opens and closes the diffuser housing. The driving motor is installed inside the diffuser housing, and a rotary shaft of the driving motor rotates with power supply. The spiral shaft connects to the rotary shaft and a screw thread forms on the exterior of the spiral shaft. The connector is connected to the diffuser cone and the spiral shaft and makes the diffuser cone move upward and downward by rotation of the spiral shaft.
