[0052] The above content is the basic structural solution of the present utility model. Compared with the prior art, first, the present utility model has at least 2 air outlet accessories 1, replacing the single-form air outlet accessory 1 in the prior art. Each air outlet accessory 1 can have an air outlet main body 12 with different shapes, so that users can obtain a diversified hair combing experience with different air outlets. Second, each air outlet accessory 1 has a modular design, that is, the same disassembly and assembly structure, and a connection lock groove 13 is formed to cooperate with the rocker-type quick-release connection block 22 on the hair comb handle 2 to achieve quick disassembly and assembly.

[0053] The disassembly and assembly operation of the present utility model is as follows: Referring to Figure 4 , the user presses the pressing end 222 to make the locking end 221 tilt up, so that the locking end 221 leaves the connecting lock groove 13, thereby releasing the connection lock between the air outlet accessory 1 and the comb handle 2. At this time, the air outlet accessory 1 and the comb handle 2 can be separated. After selecting the next air outlet accessory 1, press the pressing end 222 to make the locking end 221 tilt up. The air outlet accessory 1 approaches the comb handle 2, so that the locking end 221 is aligned with the connecting lock groove 13. Release the pressing end 222, and under the action of the elastic reset member 23, the toggle-type quick-release connecting block 22 automatically resets, that is, the locking end 221 is snapped into the connecting lock groove 13, so that the air outlet accessory 1 and the comb handle 2 form a locked connection.

[0054] Further, referring to Figure 5 , the connecting lock groove 13 has an anti-disengagement step 131, and the locking end 221 has a hook portion 2211. When the locking end 221 is inserted into the connecting lock groove 13, the hook portion 2211 abuts against the anti-disengagement step 131 and forms a vertical limit anti-disengagement fit. Of course, the toggle-type quick-release connecting block 22 can still rotate to unlock the locked connection or form a locked connection.

[0055] Preferably, referring to Figure 2 , a baffle plate 211 is provided at the end of the air inlet flow channel 21. Through the setting of the baffle plate 211, firstly, during the use process, it can block and filter the fluid in the air inlet flow channel 21, that is, it can prevent large-size impurities from entering the air outlet flow channel 14; secondly, during the disassembly and assembly process, the air inlet flow channel 21 of the comb handle 2 will be partially exposed, and the baffle plate 211 can effectively block external impurities from entering the air inlet flow channel 21.

[0056] In order to enrich the usage functions, especially when there are electrical components in the air outlet accessory 1, in order to realize the power supply and control of the electrical components, the adopted structural solution is: Referring to Figure 3 、 Figure 7 , the comb handle 2 is provided with a plug hole 24, a conductive bracket 25 is arranged in the plug hole 24, and the conductive bracket 25 is electrically connected to the circuit board assembly 3; an electrode post 15 is provided in the air outlet base 11, and the electrode post 15 can be inserted into the electrode post 15 and form an electrical connection.

[0057] Embodiment 2

[0058] There are various types of air outlet bodies 12. This embodiment provides 3 preferred solutions, which are specifically as follows:

[0059] 1. Referring to Figures 6 to 7, the air outlet body 12 is a unidirectional air outlet bracket 6. A plurality of air outlet holes 61 communicating with the air outlet flow channel 14 are formed on the front end face of the unidirectional air outlet bracket 6. A first heat conducting sheet 62 is further arranged on the front end face of the unidirectional air outlet bracket 6. A first heating element 63 is arranged inside the heat conducting sheet. The first heating element 63 is electrically connected to the electrode post 15.

[0060] During the use of the unidirectional air outlet bracket 6, the air outlet mode is unique and does not have an adjustment function. Through the arrangement of the first heating element 63 and the first heat conducting sheet 62, the function of heating and temperature rising can be achieved. Users can selectively start or stop the first heating element 63 according to their own needs to obtain the function of blowing hot air or cold air.

[0061] According to the basic effect of fluid flow, the air volume is larger and the air speed is faster at the position closer to the air inlet flow channel 21. Therefore, if the air outlet flow channel 14 is in the shape of a straight cylinder with an equal cross-sectional area, the air outlet speed will be uneven. To eliminate the above defects, the adopted structural setting is that the air outlet flow channel 14 is in a conical shape, and the cross-sectional area of the air outlet flow channel 14 gradually decreases from bottom to top. Through the change of the shape, the fluid can obtain a pressurizing effect, so that the air outlet effect of the fluid at the end of the air outlet flow channel 14 is closer to that at the beginning.

[0062] II. Refer to Figure 8 , the air outlet body 12 is a bidirectional arc-shaped air outlet bracket 7. A plurality of first forward air outlet openings 71 and first reverse air outlet openings 72 are formed on the bidirectional arc-shaped air outlet bracket 7. The first forward air outlet openings 71 and the first reverse air outlet openings 72 are arranged at intervals along the circumferential direction. A rotatable air guiding bracket 73 is arranged in the air outlet flow channel 14 of the bidirectional arc-shaped air outlet bracket 7. A wind shielding portion 731 is arranged on the air guiding bracket 73. The wind shielding portion 731 can block one of the first forward air outlet openings 71 and the first reverse air outlet openings 72, so that the other of the first forward air outlet openings 71 and the first reverse air outlet openings 72 is communicated with the air outlet flow channel 14.

[0063] During use, the user operates the air guiding bracket 73 to change the relative position relationship between the air guiding bracket 73 and the bidirectional arc-shaped air outlet bracket 7, so as to control the air outlet direction of the fluid (the first forward air outlet opening 71 or the first reverse air outlet opening 72). At the same time, the air outlet openings are arranged at intervals along the circumferential direction. When a plurality of first forward air outlet openings 71 / first reverse air outlet openings 72 are discharging air, a vortex air flow (forward or reverse) can be formed along the outer peripheral side of the air outlet accessory 1 to better perform the hair curling operation.

[0064] Further, a second heating element 74 is provided inside the bidirectional arc-shaped air outlet bracket 7, and the second heating element 74 is electrically connected to the electrode post 15. By providing the second heating element 74, the function of heating and temperature rising can be achieved. Users can selectively start or stop the second heating element 74 according to their own needs to obtain the function of blowing hot air or cold air.

[0065] III. Referring to Figures 9 to 13 , the air outlet main body 12 is a three-way arc-shaped air outlet bracket 8. A plurality of direct-blow air outlets 81 communicating with the air outlet flow channel 14 are provided on the front end face of the three-way arc-shaped air outlet bracket 8. A second forward air outlet 82 and a second reverse air outlet 83 identical to the air outlet flow channel 14 are provided on the rear end face of the three-way arc-shaped air outlet bracket 8;

[0066] A wind guiding assembly 84 is provided in the air outlet flow channel 14 of the three-way arc-shaped air outlet bracket 8, and the wind guiding assembly 84 can be communicated with any one of the direct-blow air outlet 81, the second forward air outlet 82, and the second reverse air outlet 83.

[0067] During use, the user operates the wind guiding assembly 84 to change the relative positional relationship between the wind guiding assembly 84 and the three-way arc-shaped air outlet bracket 8, thereby realizing the control of the air outlet direction of the fluid (the direct-blow air outlet 81, the second forward air outlet 82, and the second reverse air outlet 83).

[0068] The further structure is as follows: The wind guiding assembly 84 includes a fixed bracket 841 and a movable bracket 842 rotatably arranged in the fixed bracket 841; a first outer air outlet channel 8411 opposite to the direct-blow air outlet 81, a second outer air outlet channel 8412 opposite to the second forward air outlet 82, and a third outer air outlet channel 8413 opposite to the second reverse air outlet 83 are provided on the fixed bracket 841; a first inner air outlet channel 8421, a second inner air outlet channel 8422, and a third inner air outlet channel 8423 are provided on the movable bracket 842. By operating the movable bracket 842, the movable bracket 842 rotates relative to the fixed bracket 841, so as to obtain the following different air outlet experiences at different rotation angles:

[0069] When the first inner air outlet channel 8421 is communicated with the first outer air outlet channel 8411, the second inner air outlet channel 8422 is blocked from the second outer air outlet channel 8412, and the third inner air outlet channel 8423 is blocked from the third outer air outlet channel 8413;

[0072] It should be noted that other technical solutions of the present utility model belong to the prior art, so they will not be elaborated here.

[0073] The above are only the preferred embodiments of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as within the protection scope of the present utility model.
