[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] See also Figure 1-4, which is a floating limit fan swing head structure 100 provided by the utility model. The floating limit fan swing head structure 100 includes a chassis 10, a turntable 20 rotatably connected to the chassis 10, and a driving component 30 arranged on the turntable 20 for driving the turntable 20 to rotate relative to the chassis 10. A limiting structure 60 is arranged on the chassis 10, and a floating limit component 40 is arranged on the turntable 20. The driving component 30 drives the turntable 20 to rotate relative to the chassis 10 until the floating limit component 40 floats and abuts against the limiting structure 60 on the chassis 10. The driving component 30 drives the turntable 20 to drive the fan blades to rotate approximately 355° relative to the chassis 10 until the floating limit component 40 floats and abuts against the limiting structure 60 on the chassis 10. Under the action of the floating limit component 40, the driving component 30 continues to drive the turntable 20 to drive the fan blades to rotate approximately 8° relative to the chassis 10. Then, the driving component 30 reversely drives the turntable 20 to drive the fan blades to rotate approximately 355° relative to the chassis 10. After the floating limit component 40 reversely floats and abuts against the limiting structure 60 on the chassis 10, under the action of the floating limit component 40, the driving component 30 continues to reversely drive the turntable 20 to drive the fan blades to rotate approximately 8° relative to the chassis 10, thereby realizing the operation of using the floating limit fan swing head structure 100 to drive the fan to achieve a 360° swing head operation. In the embodiment provided by the utility model, the driving component 30 drives the turntable 20 to rotate relative to the chassis 10 until the floating limit component 40 floats and abuts against the limit structure 60 on the chassis 10, so that there is still a certain buffer space after the floating limit component 40 abuts against the upper limit structure 60 of the chassis 10, so that the driving component 30 can continue to drive the turntable 20 to rotate relative to the chassis 10, thereby realizing a 360° head swing operation, meeting the user's needs for all-round hair blowing, and improving the user's experience during use. In addition, the floating limit component 40 can effectively improve the smoothness of the turntable 20 driven by the driving component 30 to rotate relative to the chassis 10 while avoiding noise, thereby further improving the user's experience during use.

[0027] like Figure 1 and Figure 2As shown, the turntable 20 is provided with a mounting groove 21 for mounting a floating limit assembly 40, and the floating limit assembly 40 includes a slider 41, a first spring 42 and a second spring 43 disposed in the mounting groove 21, and a slider cover 44 for mounting the slider 41 in the mounting groove 21, and the slider 41 is elastically connected to the mounting groove 21 by the spring. After the driving assembly 30 drives the turntable 20 to rotate 335° in the forward or reverse direction relative to the chassis 10 until the slider 41 abuts against the limit structure 60 on the chassis 10, a buffer space is formed between the slider 41 and the mounting groove 21 of the turntable 20 by the first spring 42 or the second spring 43, and then under the action of the elastic force of the first spring 42 or the second spring 43, the driving motor 31 can continuously drive the turntable 20 to rotate 8° relative to the chassis 10, thereby realizing the operation of driving the fan blades to swing 360° by using the floating limit fan swing structure 100.

[0028] like Figure 3 and Figure 4 As shown, the first spring 42 and the second spring 43 are symmetrically arranged on the inner wall of the mounting groove 21, and the two ends of the slider 41 have a limiting shaft 411. The driving assembly 30 drives the turntable 20 to drive the slider 41 to abut against the limiting structure 60 of the chassis 10, and the limiting shaft 411 of the slider 41 is embedded in the first spring 42 or the second spring 43. By symmetrically arranging the first spring 42 and the second spring 43 on the inner wall of the mounting groove 21, it can be effectively guaranteed that after the driving assembly 30 drives the turntable 20 to drive the slider 41 to abut against the limiting structure 60 of the chassis 10, the limiting shaft 411 of the slider 41 is embedded in the first spring 42 or the second spring 43 with accuracy, thereby effectively ensuring that the slider 41 abuts against the first spring 42 or the second spring 43 and forms a buffer space. In the embodiment provided by the utility model, a mounting boss 211 for mounting the first spring 42 and the second spring 43 is also provided on the inner wall of the mounting groove 21. By installing the first spring 42 and the second spring 43 on the mounting boss 211 of the mounting groove 21, the stability of the first spring 42 and the second spring 43 installed in the mounting groove 21 of the turntable 20 can be effectively guaranteed, preventing the first spring 42 and the second spring 43 from falling off from the mounting groove 21 and causing failure of the floating limit assembly 40.

[0029] like Figure 1As shown, the limiting structure 60 is a limiting rib, and the driving assembly 30 includes a driving motor 31 fixed on the turntable 20 and a gear 32 sleeved on the output shaft of the driving motor 31. The driving motor 31 drives the gear 32 to mesh with the chassis 10. In the embodiment provided by the utility model, the chassis 10 is provided with a rotating part 11, a transmission part 12 and a limiting part 13, and the transmission part 12 is provided with an inner gear for meshing with the gear 32. After the driving motor 31 drives the turntable 20 to rotate 335° in the forward or reverse direction relative to the chassis 10 until the slider 41 abuts against the limiting rib on the chassis 10, a buffer space is formed between the slider 41 and the mounting groove 21 of the turntable 20 through the first spring 42 or the second spring 43, and then under the action of the elastic force of the first spring 42 or the second spring 43, the driving motor 31 can continuously drive the turntable 20 to rotate 8° relative to the chassis 10, thereby realizing the operation of driving the fan blade 360° swing head by the floating limiting fan swing head structure 100. By utilizing the driving gear 32 of the driving motor 31 to mesh with the inner gear on the transmission part 12 of the chassis 10, the stability of the turntable 20 driven by the driving motor 31 to rotate forward or reverse relative to the chassis 10 can be effectively guaranteed, the driving structure can be simplified, and the driving efficiency can be improved. In addition, a limiting groove is set on the limiting part 13, and the driving motor 31 drives the turntable 20 to rotate relative to the chassis 10 along the limiting groove. By utilizing the driving motor 31 to drive the turntable 20 to rotate along the limit groove relative to the chassis 10, the displacement of the turntable 20 relative to the chassis 10 can be effectively limited, thereby further improving the displacement accuracy of the turntable 20 relative to the chassis 10 and avoiding collisions between the turntable 20 and the chassis 10, thereby causing wear.

[0030] like Figure 1 and Figure 2As shown, the floating limit fan swing head structure 100 also includes a rotating shaft 50, which passes through the turntable 20 and is embedded in the chassis 10, so that the turntable 20 is rotatably connected to the chassis 10. The rotating shaft 50 can effectively ensure the stability of the turntable 20 when rotating relative to the chassis 10, and avoid relative displacement between the turntable 20 and the chassis 10, thereby effectively improving the stability and accuracy of the turntable 20 when driving the fan blades to rotate. In the embodiment provided by the present utility model, the turntable 20 has a first mounting hole 22 for the rotating shaft 50 to be embedded, and the chassis 10 has a second mounting hole 111 for the rotating shaft 50 to be embedded, and the rotating shaft 50 passes through the first mounting hole 22 of the turntable 20 and is embedded in the second mounting hole 111 of the chassis 10. The first mounting hole 22 and the second mounting hole 111 fit with the outer edge surface of the rotating shaft 50, thereby effectively ensuring the fit between the rotating shaft 50 and the first mounting hole 22 and the second mounting hole 111, and further effectively ensuring the stability of the rotation connection between the turntable 20 and the chassis 10 through the rotating shaft 50. A shaft sleeve 51 is also provided at the bottom of the chassis 10, and a locking member passes through the rotating shaft 50 and is locked on the shaft sleeve 51, so that the rotating shaft 50 is installed in the turntable 20 and the chassis 10. By using a locking member such as a bolt, a stud and a pin to pass through the rotating shaft 50 and be locked in the shaft sleeve 51, the stability of the fixed connection between the rotating shaft 50 and the shaft sleeve 51 can be effectively ensured, thereby ensuring the stability of the rotating shaft 50 installed between the turntable 20 and the chassis 10.
