[0052] Here, the technical solutions in the embodiments (or "implementations") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0053] If there are terms related to directional indications or positional relationships in the embodiments of this application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components in a specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first" and "second" in the embodiments of this application are only used for the purpose of convenience of description and should not be understood as indicating or implying relative importance.

[0054] In order to facilitate understanding of the technical solution of the present disclosure, the hair dryer of the present disclosure is described in detail below with reference to the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.

[0055] See also Figures 1 to 3 As shown, an embodiment of the present disclosure provides a hair dryer, including a hair dryer body 10 and an accessory assembly 20 detachably connected to the hair dryer body 10. The accessory assembly 20 can be an accessory such as a curling iron, a comb nozzle, and a fluffing nozzle.

[0056] The hair dryer body 10 is provided with an air duct 19 inside. The surface of the hair dryer body 10 is provided with an air outlet 18 connected to the air duct 19. A mounting groove 11 is provided near the air outlet 18, and an elastic limiter 12 is provided in the mounting groove 11. The accessory assembly 20 includes a mounting portion 21, which extends along the axial direction X of the accessory assembly 20. The mounting portion 21 is used to be inserted into the mounting groove 11. The mounting portion 21 is provided with a limiting groove 22. When the mounting portion 21 is inserted into the mounting groove 11, the limiting groove 22 is used to engage with the elastic limiter 12 to limit the mounting portion 21 within the mounting groove 11, thereby achieving assembly of the accessory assembly 20 with the hair dryer body 10. Optionally, the notch 111 of the mounting groove 11 is along the axial direction of the hair dryer body 10, the elastic limiter 12 can be deformed along the radial direction Y of the hair dryer body 10, and the opening of the limiting groove 22 is along the radial direction Y of the mounting portion 21.

[0057] See also Figures 4 to 6 As shown, through the above arrangement, the hair dryer disclosed in the present invention has a mounting groove 11 and an elastic limiting member 12 provided at the front of the hair dryer body 10 for allowing the mounting portion 21 of the accessory assembly 20 to extend therein, and a limiting groove 22 is provided on the outer wall of the mounting portion 21, and the accessory assembly 20 can be inserted into the mounting groove 11 of the hair dryer body 10 along the axial direction X through the mounting portion 21, as shown in FIG. Figure 4 During the assembly process, when the end face of the mounting portion 21 contacts the elastic stopper 12, the elastic stopper 12 can be squeezed to deform the elastic stopper 12 under force, and move in the radial direction Y away from the mounting portion 21 (upward in the figure), as shown. Figure 5 When the mounting portion 21 is assembled to the inner wall of the limiting groove 22 and contacts the elastic limiting member 12, the elastic limiting member 12 recovers its deformation under the action of the elastic rebound force and rebounds toward the limiting groove 22 until the elastic limiting member 12 is engaged in the entire limiting groove 22, limiting the axial displacement (i.e., axial direction X) of the accessory assembly 20 relative to the hair dryer body 10, so that the mounting portion 21 is installed in place, thereby stably fixing the accessory assembly 20 on the hair dryer body 10. Figure 6 shown.

[0058] In this way, the accessory assembly 20 is assembled with the hair dryer body 10 through the insertion and engagement of the mounting portion 21 with the mounting slot 11. The hair dryer body 10 and the accessory assembly 20 are secured together through the engagement of the elastic retainer 12 with the retaining slot 22. The thickness, material, and angle of the elastic retainer can be adjusted to meet actual needs, controlling its elastic force. Its high ductility allows for the optimal insertion and removal force to be designed based on customer needs, facilitating assembly and disassembly, extending the product's lifespan, and reducing wear.

[0059] In some optional embodiments, the hair dryer body 10 includes a head 171 and a grip portion 172. The head 171 is used to be assembled with the accessory assembly 20. The grip portion 172 is convenient for the user to hold. The head 171 includes a first end (the left end shown in the figure) and a second end (the right end shown in the figure) arranged opposite to each other along the axial direction X. The air outlet 18 and the mounting groove 11 are both provided at the first end of the head 171, that is, the first end of the head 171 is the mounting side for assembling the accessory assembly 20. In this way, when the accessory assembly 20 is assembled with the head 171, the air outlet 18 can be directed towards the accessory assembly 20 to achieve blowing.

[0060] In some optional embodiments, the mounting slot 11 includes a slot opening 111, slot walls 112, and a slot bottom 113, meaning the mounting slot 11 is concave. The slot opening 111 of the mounting slot 11 and the air outlet 18 are both located on the end surface of the first end. Thus, the air outlet 18 and the slot opening 111 of the mounting slot 11 are located at the same end of the handpiece 171. The installation direction of the accessory assembly 20 is also the direction of air flow from the air outlet 18. When the accessory assembly 20 is assembled with the handpiece 171, the air outlet 18 can be directed toward the accessory assembly 20, achieving air blowing.

[0061] In some optional embodiments, there are multiple air outlets 18, evenly arranged along the circumference of the head 171, to achieve a more uniform air outlet effect. The mounting groove 11 surrounds the air outlet 18 along its outer periphery. That is, along the radial direction of the head 171, the mounting groove 11 is located on the outer periphery of the air outlet 18, as close as possible to the inner side wall of the head 171, thereby reducing the space occupied by the air duct 19 and reducing the impact on the blowing effect.

[0062] In some optional embodiments, the mounting groove 11 is formed in a ring shape, and the mounting portion 21 is formed in a ring shape, so that the accessory component 20 can be rotated 360° during use to facilitate the user to adjust the use direction of the accessory component 20, thereby enhancing the user's styling experience. Optionally, the number of elastic limiting members 12 can be multiple, and they are evenly arranged along the circumference, so that the connection between the accessory component 20 and the hair dryer body 10 during and after the assembly process is completed is more stable and the force is more evenly distributed. Optionally, the portion of the elastic limiting member 12 that contacts the mounting portion 21 is arc-shaped, and the end face of the mounting portion 21 is an arc-shaped surface. In the process of assembling the mounting portion 21 into the limiting groove 22, the arc surface of the mounting portion 21 is more convenient for pushing the arc-shaped portion of the elastic limiting member 12, which is beneficial for assembly.

[0063] See also Figure 1 Combined with Figures 7 and 8 As shown, in some optional embodiments, the hair dryer body 10 includes an inner cylinder 13 , an annular cover 14 and an elastic structure 15 .

[0064] An annular connecting portion 131 is provided on the outer wall of the inner cylinder 13 , and an air outlet 18 is provided at a first end (the left end as shown in the figure) of the inner cylinder 13 along the axial direction X.

[0065] The annular cover 14 is sleeved on the inner cylinder 13 from the first end thereof and connected to the annular connecting portion 131. The annular space between the inner wall of the annular cover 14 and the outer wall of the inner cylinder 13 forms the mounting groove 11.

[0066] The elastic structure 15 includes an annular body 151, which is connected between the annular cover 14 and the annular connecting portion 131. The annular body 151 is provided with an elastic stopper 12 radially extending along the side of the annular body 151 facing the annular cover 14. Optionally, the mounting groove 11 is formed in an annular shape, the mounting portion 21 is formed in an annular shape, the elastic stoppers 12 are evenly arranged along the circumference of the annular body 151, and the stopper groove 22 is formed in an annular shape along the circumference of the mounting portion 21.

[0067] During assembly, the annular cover 14, elastic structure 15, and annular connecting portion 131 are first fixed together to form a single unit. The annular space between the inner wall of the annular cover 14 and the outer wall of the inner cylinder 13 forms an annular mounting groove 11. Accordingly, the mounting portion 21 is configured as an annular shape to match the annular mounting groove 11, and the retaining groove 22 is arranged along the circumference of the mounting portion 21. This allows the accessory assembly 20 to rotate 360° during use, making it easier for the user to adjust the orientation of the accessory assembly 20 and enhancing the user's styling experience.

[0068] Optionally, the elastic structure 15 can be made of sheet metal, the annular body 151 can be a sheet metal connecting piece, and the elastic limiter 12 can be a sheet metal spring piece, which has relatively reliable mechanical properties. The sheet metal spring piece after stamping and bending can adjust its buckle angle according to the mounting portion 21 of the accessory component 20. The rigidity of the sheet metal material is more ductile than that of plastic, which can extend the service life of the product and overcome the risk of deformation and failure of plastic parts in high temperature environments. After the sheet metal spring piece is assembled, it can form a relatively fixed card point, which will not easily cause the phenomenon of alignment deviation as in the magnetic buckle method. At the same time, there is no need to embed magnets in the accessory component 20 and set metal parts in the hair dryer body 10 to meet the magnetic buckle requirements, thereby saving corresponding cost control. The material of the elastic structure is not limited to sheet metal, and plastic parts and other materials with good ductility can also be selected. The material of the elastic structure can also be used in combination with sheet metal and plastic buckles to further reduce costs while ensuring a stable connection effect.

[0069] Compared to the common snap-on fastening method on the market, it has higher wear resistance and mechanical ductility. Conventional snap-on fastening methods require plastic parts to interlock with each other to connect the hair dryer body and accessories. During this process, the plastic parts will wear at the corresponding snap-on positions, and the impact strength of the plastic parts will gradually weaken. This will affect the product assembly design, resulting in running-in gaps, gradually shortening the product lifespan, and causing the connection between the hair dryer body and accessories to loosen, affecting the user experience.

[0070] In some optional embodiments, an annular connecting portion 131 may be provided on one side close to the annular cover 14 for abutting against the mounting portion 21. Optionally, the annular sealing member 146 may be a silicone gasket. In this way, when the elastic limiting member 12 and the limiting groove 22 are engaged and limited so that the mounting portion 21 is installed in place, the silicone gasket seal can prevent the formation of a gap between the accessory assembly 20 and the mounting groove 11 that is prone to air leakage, and increase the resistance of the accessory assembly 20 to rotation relative to the hair dryer body 10. When the user does not actively rotate the accessory assembly 20, the accessory assembly 20 can also be relatively stably maintained at the angle desired by the user until the user forcefully turns the accessory assembly 20, thereby improving the user experience.

[0071] In some optional embodiments, the annular cover body 14 is provided with a through hole portion 141, and the through hole portion 141 penetrates the annular cover body 14 along the radial direction Y of the annular cover body 14. At least a portion of the elastic limiting member 12 passes through the through hole portion 141 and extends into the mounting groove 11. In this way, the annular main body 151 of the elastic structure 15 is located between the annular cover body 14 and the inner cylinder 13, and the elastic limiting member 12 can pass through the through hole portion 141 of the annular cover body 14 and extend into the mounting groove 11 to be engaged and limited with the limiting groove 22 of the mounting portion 21 of the additional component 20. Optionally, when there are multiple elastic limiting members 12 and they are evenly arranged along the circumference, the number of the through hole portions 141 can correspond to the number of the elastic limiting members 12 and be evenly arranged along the circumference, so as to ensure that each elastic limiting member 12 can pass through the through hole portion 141 corresponding to the position and extend into the mounting groove 11.

[0072] See also Figure 9 As shown, in some optional embodiments, the outer wall of the annular cover body 14 corresponds to the position of the through-hole portion 141, and is formed with a slot 142 connected to the through-hole portion 141. The elastic limiting member 12 includes a clamping portion 121 and a protruding portion 122. The clamping portion 121 is connected to the outer wall of the annular main body 151 and is clamped with the slot 142. The protruding portion 122 is connected to the clamping portion 121 and extends into the mounting groove 11 through the through-hole portion 141. In this way, the elastic limiting member 12 is clamped with the slot 142 of the annular cover body 14 through the clamping portion 121, which can stabilize the position of the elastic limiting member 12 in the slot, and reduce the occurrence of position deviation of the elastic limiting member 12 when the elastic limiting member 12 is deformed. Optionally, the protruding portion 122 is arc-shaped, and the end face of the mounting portion 21 is arc-shaped. When the mounting portion 21 is assembled into the limiting groove 22 , the arc surface of the mounting portion 21 is more convenient for pushing the arc-shaped protrusion 122 , which is beneficial for assembly.

[0073] In this embodiment, both ends of the outer wall of the annular cover body 14 along the axial direction X correspond to the position of the through hole portion 141, and are formed with a slot 142 communicating with the through hole portion 141. Figure 3 As shown, the two ends of the raised portion 122 of the elastic limiting member 12 are respectively connected to a clamping portion 121, and the two clamping portions 121 are respectively clamped in the two clamping grooves 142 of the annular cover body 14, so that the elastic limiting member 12 and the annular cover body 14 are more firmly connected to each other.

[0074] In some optional embodiments, to secure the annular cover 14, the elastic structure 15, and the annular connecting portion 131 to each other as a whole, one of the annular cover 14 and the annular connecting portion 131 is provided with a snap-fitting member 143, and the other is provided with a connecting groove 132 that engages with the snap-fitting member 143. A through-slot is provided in the annular main body 151 at a position corresponding to the connecting groove 132. In this embodiment, the annular cover 14 is provided with the snap-fitting member 143, and the annular connecting portion 131 is provided with the connecting groove 132.

[0075] In this way, when the annular cover body 14, the elastic structure 15 and the annular connecting portion 131 are connected, the clamping member 143 passes through the through groove and connects with the connecting groove 132, and is clamped between the annular cover body 14 and the annular connecting portion 131 to form a stable installation of the three.

[0076] Furthermore, the clamping member 143 includes at least one cylindrical clamping post 144 and at least one elongated buckle 145, evenly arranged along the circumference of the annular cover 14. The connecting groove 132 includes a first connecting groove 133 and a second connecting groove 134. The first connecting groove 133 matches the shape, position, and number of the clamping post 144, while the second connecting groove 134 matches the shape, position, and number of the buckle 145. The through groove includes a first through groove 153 and a second through groove 154. The first through groove 153 matches the shape, position, and number of the clamping post 144, while the second through groove 154 matches the shape, position, and number of the buckle 145. In this embodiment, the clamping post 144 is cylindrical, and the buckle 145 is elongated. Accordingly, the first connecting groove 133 is a circular groove, and the second connecting groove 134 is an elongated groove. The first through slot 133 is a circular slot, and the second through slot 134 is an elongated slot, and is formed on the outer wall of the annular body 151 .

[0077] In this way, when the annular cover 14, the elastic structure 15 and the annular connecting portion 131 are connected, the clamping column 144 passes through the first through slot 153 and is connected to the first connecting slot 133, and the buckle 145 passes through the second through slot 154 and is connected to the second connecting slot 134, so that the three are stably installed.

[0078] In this embodiment, there are multiple clamping columns 144 and buckles 145, which are evenly arranged along the circumference, which can improve the stability of the connection between the annular cover 14, the elastic structure 15, and the annular connecting portion 131. In addition, the clamping member 143 is configured as clamping columns 144 and buckles 145 with different structures. The length, width, and height of the clamping columns 144 and buckles 145 can be different. In this way, the connection through the connecting members of different structures can further improve the reliability of the connection.

[0079] In some optional embodiments, the hair dryer body 10 may further include an outer shell 16, which is sleeved on the inner cylinder 13 from the second end of the inner cylinder 13, and there is a gap between the end wall of the outer shell 16 and the elastic limit member 12, so that when the user installs the accessory component 20 so that the elastic limit member 12 is deformed under force, the elastic limit member 12 has a certain amount of movement space in the axial direction (i.e., axial direction X).

[0080] Furthermore, the outer shell 16 has a stopper 161 formed on one end near the mounting side, which is designed to abut against the accessory assembly 20. The stopper 161 is bent along the radial direction Y toward the inner barrel 13. An insertion interface is formed between the stopper 161 and the inner barrel 13, corresponding to the position of the mounting slot 11. This insertion interface facilitates the insertion of the mounting portion 21 into the mounting slot 11. When the elastic stopper 12 engages the stopper slot 22 to secure the mounting portion 21 in place, the end surface of the accessory assembly 20 near the inner barrel 13 abuts against the stopper 161 of the outer shell 16, stably securing the accessory assembly 20 to the hair dryer body 10.

[0081] In some optional embodiments, the interior of the outer shell 16 is connected to the interior of the inner cylinder 13 to form the air duct 19, and the end of the outer shell 16 away from the inner cylinder 13 is provided with a first air inlet 162 connected to the air duct 19, and the bottom end of the outer shell 16 is provided with a second air inlet 163 connected to the air duct 19. The accessory component 20 has a third air inlet 23 adapted to the air outlet 18. In this way, when the accessory component 20 is assembled with the hair dryer body 10, the air flow enters the air duct 19 inside the head 171 from the first air inlet 162 and the second air inlet 163 of the outer shell 16, and then blows out from the air outlet 18 of the inner cylinder 13, and then blows in from the third air inlet 23 of the accessory component 20 to achieve blowing. The airflow path is as follows Figure 1 Indicated by the dotted arrow direction.

[0082] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application shall be included in the scope of protection of this application.
