[0036] like Figures 1 to 4 As shown, the fan blades 200 are coaxially arranged on the head 100, and several heating components 310 are arranged along the circumference of the head 100, and each heating component 310 is movably connected to the head 100. Therefore, when the heating component 310 extends to the range of the fan blades 200, the fan is in hot air mode, and the airflow flows out from the area with the heating component 310, and the heat is directly transferred to the air and blown out with the rotation of the fan blades 200 to achieve a heating effect. When the heating wire 312 is separated from the range of the fan blades 200, the heating component 310 is hidden, and the fan is in cold air mode. The airflow flows out from the area without the heating component 310 and will not be interfered by the heating component 310. The hot and cold air modes will not be affected by each other, thereby improving the air inlet and outlet efficiency of the hot air mode and the cold air mode.

[0037] In some specific embodiments of the present invention, in order to form a larger coverage area between the heating wire 312 and the fan blade 200 and transfer heat more evenly, the heating element 310 is fan-shaped.

[0038] Specifically, the head 100 includes a middle shell 110, a rear shell 120, and a front shell 130. The rear shell 120 is coaxially arranged on the middle shell 110, and a rear mesh cover 121 is coaxially arranged on the rear shell 120.

One of the front shell 130 and the rear shell 120 is rotatably connected to the fan blade 200. One of the front shell 130 and the rear shell 120 is arranged on the air intake side of the fan blade 200, and the other is arranged on the air discharge side of the fan blade 200. In this specific embodiment, the rear shell 120 is rotatably connected to the fan blade 200, and the front shell 130 is located on the air discharge side of the fan blade 200.

[0039] In some specific embodiments of the present invention, the plurality of heating components 310 can all move along the radial direction of the handpiece 100. Figure 3 and Figure 4 As shown, in this specific embodiment, two heating components 310 are provided, and the two heating components 310 are symmetrically arranged at the upper and lower ends of the head 100. The two heating components 310 can move in the up and down directions. Then, when the two heating components 310 approach the axis along the radial direction of the head 100, the two heating components 310 block the fan blades 200, and the air flow flows out from the area with the heating components 310, and the heat is directly transferred to the air.

[0040] In some specific embodiments of the present invention, a shaking support mechanism 400 is further included. The shaking support mechanism 400 is connected to the head 100. The head 100 is rotatably arranged on the shaking support mechanism 400. The shaking support mechanism 400 is used to change the air outlet direction. Figure 1 As shown, the head 100 is set on the shaking head support mechanism 400. Specifically, the shaking head support mechanism 400 includes a fixed seat 410, a fixed bracket and a rotating shaft. The fixed bracket is in an arc shape that matches the head 100. The fixed bracket is fixedly set at the upper end of the fixed seat 410. The rotating shaft extends in the horizontal direction. The head 100 is rotatably connected to the fixed bracket through the rotating shaft. Specifically, the head 100 rotates around the rotating shaft to realize the change of wind direction in the vertical direction.

[0041] In some specific embodiments of the present invention, the heating mechanism 300 further includes a movable component 320 , which is disposed on the handpiece 100 and connected to the heating component 310 , and the heating component 310 is movably connected to the handpiece 100 through the movable component 320 .

[0042] In some specific embodiments of the present invention, the heating component 310 includes a heating wire bracket 311 and a heating wire 312. The heating wire bracket 311 is movably arranged on the head 100. The heating wire bracket 311 can move radially along the head 100. The heating wire 312 is arranged on the heating wire bracket 311.

[0043] In some specific embodiments of the present invention, the moving component 320 includes: a gear 321 and a rack 322, one of the gear 321 and the rack 322 is set on the heating wire bracket 311, and the other is set on the head 100, the rack 322 extends along the radial direction of the head 100, and the gear 321 and the rack 322 are engaged with each other; a driving member 323, the driving member 323 is connected to the gear 321, and the driving member 323 is used to drive the gear 321 to rotate.

[0044] like Figure 2 、 Figure 5 and Figure 7 As shown, in this specific embodiment, the rack 322 is fixedly mounted on the heating wire bracket 311, and the gear 321 is rotatably mounted on the handpiece 100 via a driving member 323. The rack 322 extends radially of the handpiece 100, and the gear 321 is located on the diameter of the handpiece 100. Therefore, when the driving member 323 drives the rack 322 and the gear 321 to cooperate with each other, the heating wire bracket 311 can move radially of the handpiece 100. Specifically, the driving member 323 is a stepping motor, and the middle housing 110 has a motor slot, in which the stepping motor is mounted.

[0045] In some specific embodiments of the present invention, the heating wire bracket 311 has two accommodating holes 3111, and the two accommodating holes 3111 are arranged along the radial direction of the head 100. The heating wire 312 is arranged in the accommodating hole 3111 close to the axis of the head 100. Figure 5 As shown, the two accommodating holes 3111 extend in the up and down directions, and the heating wire 312 is arranged in the accommodating hole 3111 at the lower end. Therefore, when the heating mode is started, the connection end of the heating wire bracket 311 and the head 100 is located at the end away from the heating wire 312 to control the temperature distribution around the heating wire 312, avoid local overheating around the heating wire 312, and protect the adjacent structures from the influence of high temperature.

[0046] In some specific embodiments of the present invention, the heating mechanism 300 further includes a limiting component 330 , which is connected to the head 100 , and is connected to the heating component 310 , and is used to limit the moving direction of the heating component 310 .

[0047] In some specific embodiments of the present invention, the limiting assembly 330 includes a limiting baffle 331 and a limiting slide rail 332. One of the limiting baffle 331 and the limiting slide rail 332 is set on the machine head 100, and the other is set on the heating wire bracket 311. The limiting baffle 331 is slidably connected to the limiting slide rail 332 to limit the moving direction of the heating wire bracket 311 on the machine head 100.

[0048] like Figure 6As shown, there are four limiting slide rails 332 on the middle shell 110, and each heating wire bracket 311 is correspondingly provided with two limiting slide rails 332. The limiting slide rails 332 extend along the moving direction of the heating wire bracket 311, and a groove is provided on the limiting slide rail 332. The heating wire bracket 311 is provided with a protrusion corresponding to the groove. The protrusion is placed in the corresponding groove, so that the heating wire bracket 311 can move along the channel restricted by the heating wire 312 slide rails, thereby limiting the movement of the heating wire bracket 311 extending toward the fan blade 200 and leaving the range of the fan blade 200, and at the same time ensuring that the heating component 310 does not fall backwards, preventing the heating wire 312 from getting stuck in the fan blade 200. Furthermore, the heating wire bracket 311 is provided with a limit baffle 331, the number of which corresponds to the number of protrusions, and each protrusion is provided with a limit baffle 331. The limit baffle 331 cooperates with the limit slide rail 332 to fix the sliding path of the heating wire bracket 311 on the limit slide rail 332 to prevent the heating bracket from sliding left and right or shaking back and forth.

[0049] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
