[0055] Of course, in some embodiments, the first component 100 described above may also be a single housing or three housings, and this is not limited here.

[0056] Understandably, referring to Figure 4 and Figure 5 In this embodiment of the utility model, the second component 200 includes a second inner shell 240 and a second outer shell 250 sleeved on the outside of the second inner shell 240, wherein the second positioning part 210 is disposed on the second inner shell 240.

[0057] With the above structure, the second component 200 forms a double-layer structure through the second inner shell 240 and the second outer shell 250. The second positioning part 210 is disposed in the second inner shell 240, and the second outer shell 250 can protect the second positioning part 210. The second component 200 adopts a double-layer structure, and the inner second inner shell 240 can also play a role in heat insulation, while the outer second outer shell 250 has no heat insulation requirements. The double-layer structure saves the amount of heat insulation material used.

[0058] Of course, in some embodiments, the first positioning part 110 may also be disposed on the first housing 130, and the second positioning part 210 may also be disposed on the second housing 250.

[0059] It should be noted that in some embodiments, the second component 200 may be a single housing or three housings, which is not limited here. It can also be understood that the first component 100 is a single-layer housing and the second component 200 is a double-layer housing, which is not limited here.

[0060] Understandably, referring to Figures 3 to 6 In this embodiment of the present invention, the first positioning part 110 is a positioning groove, and the second positioning part 210 includes a positioning post 211. The positioning post 211 is engaged with the positioning groove so that the second component 200 is fixed to the first component 100. The positioning post 211 is configured to be able to extend and retract relative to the second component 200.

[0061] The design incorporates a positioning groove and a positioning post 211, allowing the positioning post 211 to extend and retract relative to the second component 200. The snap-fit ​​design of the positioning groove and the positioning post 211 ensures precise alignment of the second component 200 with the first component 100, thereby maintaining the stability of the airflow direction. Because the positioning post 211 is extendable and retractable, the second component 200 can be adjusted within a certain range to adapt to different usage needs or blow-drying angles. Users can easily adjust the positioning post 211 according to their needs, making the installation and removal of the second component 200 more convenient. The tight snap-fit ​​of the positioning groove and the positioning post 211 helps maintain the airtightness of the ventilation duct 300, preventing airflow leakage and improving blow-drying efficiency. By providing a stable and adjustable airflow angle, users can more easily achieve various hairstyles, enhancing user satisfaction.

[0062] It should be noted that in this embodiment of the utility model, the positioning groove is integrally formed on the first component 100. Of course, in some embodiments, a positioning seat can also be installed on the outside of the first component 100, and the positioning seat is recessed to form the above-mentioned positioning groove.

[0063] It is conceivable that in some other embodiments, one of the first positioning part 110 and the second positioning part 210 may be configured as a toothed ring with its teeth located on the inner or outer side of the ring, and the other may be configured as a retractable positioning post 211 or an elastic positioning pin, without limitation here.

[0064] Of course, in some embodiments, the first positioning part 110 may also be disposed on the second component 200, and the second positioning part 210 may also be disposed on the first component 100, which is not limited here.

[0065] Specifically, refer to Figure 3 , Figure 5 and Figure 6 In this embodiment of the present invention, the second positioning part 210 further includes an elastic reset member 212, which is disposed between the positioning post 211 and the second component 200. The elastic reset member 212 is used to drive the positioning post 211 to move in the direction of engaging with the positioning groove.

[0066] With the above structure, after the positioning post 211 separates from the positioning groove, the elastic reset member 212 can automatically return to its original state, driving the positioning post 211 to reset and prepare for the next snap-fit; the elastic force of the elastic reset member 212 can ensure that the position of the positioning post 211 in the groove will not be easily changed due to vibration or external force, which can prevent the positioning post 211 from accidentally falling off during use and improve the stability of the overall structure; the user can easily insert or remove the positioning post 211 into the positioning groove without using additional tools.

[0067] Specifically, refer to Figure 3 , Figure 5 and Figure 6 In this embodiment of the present invention, the second component 200 is provided with a mounting groove 220, and the mounting groove 220 is provided with an annular limiting platform 221; the positioning post 211 is provided with a limiting protrusion 2111 in the circumferential direction, the limiting protrusion 2111 is located in the mounting groove 220, and the outer side of the limiting protrusion 2111 abuts against the inner side of the annular limiting platform 221 to limit the separation of the positioning post 211 from the mounting groove 220; the elastic reset member 212 is located in the mounting groove 220, one end of the elastic reset member 212 abuts against the limiting protrusion 2111, and the other end of the elastic reset member 212 abuts against the inner wall of the mounting groove 220.

[0068] It should be noted that, in this embodiment of the utility model, the aforementioned limiting protrusion 2111 and the positioning post 211 are integrally injection molded. Integral injection molding has higher structural strength and stability, can better withstand external forces and vibrations, reduces assembly steps and the number of parts, thereby reducing production costs; or, in some other embodiments, the aforementioned limiting protrusion 2111 is a ring, and the ring and the positioning post 211 are connected by threads or snap-fit ​​connections, which are simple and easy to operate, and facilitate disassembly and maintenance.

[0069] By employing the above structure, the annular limiting platform 221 and the limiting protrusion 2111 ensure the accurate positioning of the positioning post 211 within the mounting groove 220. The outer surface of the limiting protrusion 2111 abuts against the inner surface of the annular limiting platform 221, preventing excessive sliding of the positioning post 211 and limiting its maximum travel. When the positioning post 211 is inserted into or removed from the mounting groove 220, the elastic reset member 212 deforms, providing a reset force. This design ensures that after the positioning post 211 is removed, the elastic reset member 212 can push it back to its original position, maintaining structural stability. Furthermore, the presence of the elastic reset member 212 reduces hard collisions and wear between components, extending the product's service life. This structural design not only improves the stability and durability of the hair dryer components but also enhances the user experience through the use of the elastic reset member 212, making the product more reliable and user-friendly.

[0070] Specifically, refer to Figure 3 , Figure 5 and Figure 6 In this embodiment of the invention, a positioning protrusion 2112 is provided along the axial direction of the positioning post 211, and the elastic reset member 212 is a spring. The elastic reset member 212 is sleeved on the positioning protrusion 2112 and abuts against the limiting protrusion 2111. Through the above structure, the positioning protrusion 2112 can ensure that the elastic reset member 212 is accurately aligned at a specific position, reduce assembly errors, and improve the precision of the product.

[0071] It should be noted that in some embodiments, the above-mentioned elastic reset member 212 may also be an elastic sheet or an elastic pad, etc., which is not limited here.

[0072] Understandably, referring to Figure 4 In this embodiment of the utility model, there are multiple first positioning parts 110, and the first component 100 is provided with multiple first positioning parts 110 at intervals along its circumference, that is, multiple positioning grooves.

[0073] Specifically, there are four positioning grooves, which are arranged circumferentially and at intervals along the second component 200. Therefore, when the second component 200 rotates relative to the first component 100, the four positioning grooves allow the second component 200 to be fixed in multiple different positions, providing various blow-drying angle options to meet the needs of different users. The uniform distribution of the positioning grooves helps maintain balance during rotation, reduces vibration caused by center of gravity shift, and improves the stability of the overall structure. Of course, in some embodiments, the positioning grooves may be one, two, or five, etc., and this is not limited here.

[0074] Understandably, referring to Figure 3 and Figure 5In this embodiment of the utility model, there are multiple second positioning parts 210, and multiple second positioning parts 210 are arranged at intervals along the circumference of the second component 200.

[0075] With the above structure, the multiple second positioning parts 210 provide more fixing points, making the connection between the first component 100 and the second component 200 more secure and dispersing the pressure of a single fixing point; due to the multiple fixing points, the stability of the entire structure is improved.

[0076] Specifically, in this embodiment of the present invention, there are two second positioning parts 210, which are arranged at intervals. Of course, in some embodiments, the second positioning parts 210 may be one or three, that is, it can be understood that in this embodiment, the number of first positioning parts 110 is greater than the number of second positioning parts 210, and the corresponding number can be set as needed, without limitation here.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
