The two wind wheels are respectively a first fan 11 and a second fan 12, and the shell 1 is provided with a heating body on one side of the second fan 12. When the driver drives the second fan 12 to rotate, the heating elements are simultaneously opened, air is heated by the heating elements to be warm, and the corresponding cold second fan 12 is in a heating state; when the driver drives the first fan 11 to rotate, the wind is directly blown out from the wind outlet of the housing 1, and the corresponding cold second fan 12 is in a cooling state.

In order to save materials, the driver adopts a double-shaft motor 13, the shell of the motor is fixed in the shell 1, and two driving shafts of the motor respectively extend out of two ends and respectively drive the first fan 11 and the second fan 12. In order to facilitate the cold and warm state, the corresponding fan is 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 are generally rotated together in the warm air state, it is only necessary to provide a transmission assembly between the driven shaft and the driving shaft of the second fan 12.

In order to realize the connection between the transmission seat 3 and the connecting piece 4, the transmission seat 3 is provided with a sliding opening, and one end of the connecting piece 4 is sleeved in the sliding opening. Referring to fig. 3, the connecting member 4 forms a convex sliding block 42 on the side surface, and the sliding opening is provided with a sliding way for sliding the sliding block 42, so that the connecting member 4 and the connecting seat are circumferentially fixed and axially slide.

In order to prevent the connecting piece 4 from separating from the connecting seat, the connecting piece 4 is provided with a limiting block 43 extending along the radial direction at one end of the extending sliding opening, and the limiting block 43 is used for being abutted against the inner wall of the transmission seat 3.

To achieve the lifting of the connecting element 4, the transmission assembly also comprises a clutch switch. The coupling 4 has a driving surface 44 formed on the side where the coupling is provided, and the clutch switch applies an axial force to the driving surface 44 to push the coupling 4 to slide toward the side away from the rotor 2. Accordingly, a spring 5 as an elastic member is held between the driving seat 3 and the link 4, and the elastic member slides the link 4 toward the side close to the rotor 2 and engages with the rotor 2. Thereby realizing the separation of the connecting part and the rotary head 2 through the clutch switcher. And the elastic element resets to realize the engagement of the connecting part and the rotating head 2.

Different configurations of the clutch switch can be provided according to different principles.

One end of the rotary lifting sleeve 9 is provided with a driven lug 91 sliding along the driving inclined plane, and the other end is abutted with the driving surface 44. As the driven projection 91 slides along the driving slope, the rotary lifting sleeve 9 gradually moves away from the rotary lifting seat 8 and presses the driving surface 44, thereby realizing the clutch of the transmission mechanism. Therefore, the rotary lifting seat 8 converts the rotary motion of the rotary lifting sleeve 9 into linear motion to drive the connecting piece to slide.

In order to facilitate the arrangement of the driving inclined planes, the rotary lifting seat 8 is provided with driving convex blocks 81 arranged along a smooth curve, and the driving inclined planes are positioned on two sides of the driving convex blocks 81. In order to ensure that the stress of the rotary lifting sleeve 9 is stable, at least two groups of driving lugs 81 and driven lugs 91 are arranged, and each group comprises one driving lug 81 and one driven lug 91 which are in mutual contact.
