[0016] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0017] In the description of this utility model, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] This utility model discloses a replaceable head hair styling device, including a handle body 1, a replaceable head 2 detachably connected to the handle body 1, and a hair styling component 3 disposed on the replaceable head 2 (the hair styling component 3 can be a heated straightening comb, curling iron, or hair straightener, which are conventional technologies and will not be described in detail here). The handle body 1 has an L-shaped mounting surface 11, the replaceable head 2 is fitted onto the L-shaped mounting surface 11, and a terminal block 4 is disposed at the bottom of the L-shaped mounting surface 11. The replaceable head 2 has an electrical plug 5 extending downwards to be inserted into the terminal block 4. In the implementation example, a cover plate 21 is provided on the top of the handle body 1 on the replacement head 2. The cover plate 21 is provided with an extension block 211 extending downward. A positioning groove 12 is provided on the top of the handle body 1. The extension block 211 extends into the positioning groove 12. An anti-disengagement hook 6 is also provided on the bottom of the L-shaped assembly surface 11 on the handle body 1. A hook groove 22 is provided on the replacement head 2 at the position of the anti-disengagement hook 6. The anti-disengagement hook 6 can enter and exit the hook groove 22. When the anti-disengagement hook 6 enters the hook groove 22, the anti-disengagement hook 6 hooks onto the bottom of the hook groove 22 to restrict the replacement head 2 from being pulled out.

[0019] Using the above scheme, inserting the power plug 5 into the terminal block 4 during assembly can prevent the bottom of the replacement head 2 from wobbling laterally. The extension block 211 located in the positioning groove 12 can prevent the top of the replacement head 2 from wobbling laterally. And by hooking the anti-disengagement hook 6 into the bottom of the positioning groove 12, the replacement head 2 can be prevented from being pulled out axially, making it more stable during use. The assembly is also relatively convenient. When the extension block 211 and the positioning groove 12 are aligned, the power plug 5 and the terminal block 4 are aligned and inserted in the vertical direction.

[0020] The handle body 1 is also provided with a button 7 and an elastic reset member 8 for driving the button 7 to reset (the elastic reset member 8 is preferably a spring, which can be provided with a guide shaft on the button 7, and the guide shaft can facilitate the sliding of the button and the engagement of the spring; of course, the elastic reset member 8 can also be a spring sheet). The anti-disengagement hook 6 is provided on the button 7 and slides synchronously with the button 7. Pressing the button 7 can drive the anti-disengagement hook 6 to disengage from the hook groove 22, so that the replacement head 2 can be pulled out axially. When the button 7 is released, the anti-disengagement hook 6 resets and hooks the bottom of the hook groove 22 to prevent the replacement head 2 from being pulled out.

[0021] The anti-detachment hook 6 is positioned outwards, and the hook groove 22 is located on the inner side wall of the replacement head 2. This design can cover the anti-detachment hook 6, thereby preventing the anti-detachment hook 6 from being directly exposed.

[0022] The L-shaped assembly surface 11 is also provided with an anti-detachment bracket 9. The anti-detachment hook 6 has an installation part 61 and a latching part 62. The installation part 61 is connected to the button 7. When the latching part 62 is hooked in the latching groove 22, the latching part 62 passes through the anti-detachment bracket 9 (preferably, a hole for the latching part 62 to enter and exit is provided on the anti-detachment bracket 9). The anti-detachment bracket 9 is provided with a limiting surface at the top of the latching part 62 to limit the pull-out of the anti-detachment hook 6. When the button 7 is assembled, a shaft is usually used for guided installation. If all the anti-detachment force is applied to the button 7, it is easy to break after long-term use. Moreover, the replacement process of the button 7 is relatively complicated. Therefore, the limiting surface of the anti-detachment bracket 9 is used for limiting, which can play an auxiliary limiting role and increase the stability of the structure.

[0023] The handle body 1 is also provided with an air flow channel, on which a fan 10 is provided. An air outlet 20 is provided on the handle body 1 corresponding to the air outlet end of the air flow channel. The replacement head 2 is located on the front side of the handle body 1, and the air outlet 20 is located on the rear side of the handle body 1. When the fan 10 is working, it can blow cold air into the air outlet 20 through the air flow channel, which can facilitate the cooling and styling of the hair. It can achieve multiple functions without interfering with the use, making it more practical. The air intake of the fan 10 can be achieved by opening a through hole on the handle body 1.
