The two wind wheels are a first fan 11 and a second fan 12 respectively, and a heating body is arranged on one side of the second fan 12 of the shell 1. When the driver drives the second fan 12 to rotate, the heating body is simultaneously turned on, air is heated by the heating body and is warm, and the corresponding cold second fan 12 is in a heating state; when the driver drives the first fan 11 to rotate, wind is directly blown out from the air outlet of the shell 1, and the corresponding cold second fan 12 is in a refrigerating state.
In order to save materials, a biaxial motor 13 is selected as a driver, a shell of the motor is fixed in the shell 1, and two driving shafts of the motor respectively extend out from two ends and respectively drive a first fan 11 and a second fan 12. In order to facilitate the cold and warm state, the corresponding fans are controlled to rotate, and a transmission assembly with a clutch function is arranged between the driving shaft and the corresponding wind wheel. Since the first fan 11 and the second fan 12 generally rotate together in the warm air state, only the transmission assembly is required between the driven shaft and the driving shaft of the second fan 12.
Referring to fig. 2, the transmission assembly includes a rotating head 2 and a transmission member, wherein the rotating head 2 is fixed on a driving shaft of the driver, the transmission member includes a transmission seat 3 and a connection member 4, the transmission seat 3 is fixed on a driven shaft, the connection member 4 and the transmission seat 3 are circumferentially fixed on the connection member 4 and slide along the axial direction of the driven shaft, and one end of the connection member 4 is provided with a connection portion for the rotating head 2 to engage. When the connecting piece 4 is driven to slide to the side close to the rotary head 2, the connecting part is meshed with the rotary head 2, and the driving shaft drives the driven shaft to rotate; when the connecting piece 4 is driven to slide to the side far away from the rotating head 2, the connecting part is separated from the rotating head 2, and the driving shaft independently rotates.

In order to prevent the connecting piece 4 from being separated from the connecting seat, a limiting block 43 extending radially is arranged at one end of the connecting piece 4 extending into the sliding opening, and the limiting block 43 is used for being abutted with the inner wall of the transmission seat 3.
In order to achieve lifting of the connection 4, the transmission assembly also comprises a clutch switch. The link 4 is formed with a driving surface 44 on the side where the link is provided, and the clutch switch applies an axial force to the driving surface 44 to push the link 4 to slide away from the rotor 2. Correspondingly, a spring 5 serving as an elastic member is clamped between the transmission seat 3 and the connecting member 4, and the elastic member enables the connecting member 4 to slide to the side close to the swivel 2 and engage with the swivel 2. Thereby effecting the separation of the connection and the rotor 2 by means of the clutch switch. And the elastic piece resets to realize the engagement of the connecting part and the rotary head 2.
Different configurations of the clutch switches can be provided according to different principles.
