[0014] As Figures 1 to 8 shown, it is a detachable fan, including that the fan head assembly 2 is detachably connected to the bracket assembly 1; wherein the bracket assembly 1 includes a bracket body 11 and a cantilever connection mechanism 3 provided on the bracket body 11, the cantilever connection mechanism 3 includes a fixed arm 31 and a pair of swing arms 32 rotatably connected to the fixed arm 31, and the pair of swing arms 32 can swing down to the left and right sides of the fixed arm 31 and are perpendicularly arranged with the fixed arm 31; it further includes a fan head assembly 2, the fan head assembly 2 includes a housing 21 and a motor 22 and a fan blade 23 arranged in the housing 21, and the rotating shaft of the motor 22 is connected to the fan blade 23 so as to be able to drive the fan blade 23 to rotate.
[0015] Among them, in order to enable the fan head assembly 2 to be connected to the cantilever connection mechanism 3 of the bracket assembly 1, it further includes a T-shaped connection bracket 4, as Figure 8As shown, the connecting bracket 4 includes a horizontal connecting rod 41 and a vertical connecting rod 42. Hooks 43 are respectively arranged at both ends of the horizontal connecting rod 41. Connecting grooves 33 are arranged on a pair of the swing arms 32. An angle adjusting rod 44 is arranged on the vertical connecting rod 42. A number of adjusting holes 441 are arranged at intervals on the angle adjusting rod 44. A positioning hook post 311 is arranged on the fixed arm 31. In addition, an insertion port 211 is arranged on the housing 21. A pin 46 matching the insertion port 211 is arranged on the connecting bracket 4. The connecting bracket 4 is connected to the housing 21 through the cooperation of the pin 46 and the insertion port 211. The fan head assembly 2 is further connected to the cantilever connecting mechanism 3 through the connecting bracket 4. The hook 43 is connected to the connecting groove 33. The angle adjusting rod 44 is connected to the positioning hook post 311 through the adjusting holes 441. Among them, by combining different adjusting holes 441 with the positioning hook post 311, the up and down orientation of the fan head assembly 2 can be adjusted.
[0016] To facilitate the control of the movement of the swing arm 32, as Figure 5 shown in Figure 6 shown, the cantilever connecting mechanism 3 further includes a swing arm drive motor 34 and a central screw 35 arranged on the fixed arm 31. At least part of a gear 321 is arranged at one end of a pair of the swing arms 32 where they are connected to the fixed arm 31. The gear 321 meshes with the central screw 35. When the swing arm drive motor 34 drives the central screw 35 to rotate forward, a pair of the swing arms 32 can swing downward from the erected state to the horizontal state and be perpendicularly arranged with the fixed arm 31; when the swing arm drive motor 34 drives the central screw 35 to rotate reversely, a pair of the swing arms 32 can swing upward from the horizontal state to the erected state and be clamped on both sides of the fixed arm 31.

[0020] Further, a heating element (not shown in the figure) is provided on the swing arm 32. Further, ventilation holes 322 are also provided on the wall of the swing arm 32, and the ventilation holes 322 are arranged on the back surface of the heating element. In this way, after the fan head assembly is hooked up, it can be used as a hot air device.
[0021] Compared with the prior art, the present invention has obvious advantages and beneficial effects. First, the bracket assembly 1 and the fan head assembly 2 are designed as two separable components, so that the fan head assembly 2 can be detached separately, which not only helps to save packaging space and improve transportation efficiency, but also helps to clean and maintain the fan head assembly 2 separately, and well solves the problem of inconvenient cleaning caused by the fact that the fan head assembly 2 and the bracket in the prior art must be moved together. Second, by providing the T-shaped connecting bracket 4, the bracket assembly 1 and the fan head assembly 2 can be well connected. In particular, through the two hooks 43, an angle adjustment rod 44 and the cantilever connection mechanism 3 of the bracket assembly 1 form a three-point connection, so that the fan head assembly 2 forms a stable connection relationship, greatly reducing the excessive vibration caused by the rotation of the motor 22 and the fan blade 23 in the fan head assembly 2. Third, a number of adjustment holes 441 are arranged at intervals on the angle adjustment rod 44, and a positioning hook post 311 is provided on the fixed arm 31. The angle adjustment rod 44 is connected to the positioning hook post 311 through the adjustment holes 441. By connecting different adjustment holes 441, it is convenient to adjust the orientation of the fan head assembly 2 during use to meet people's usage requirements.
