It should be understood that various changes can be made to the embodiments described in this specification and that such changes are contemplated and within the scope of the present application.

[0040] The utility model provides a kind of accessory 10 for hair dryer, and the accessory 10 is suitable for hair dryer.Hair dryer includes host computer, and accessory 10 is detachably fixedly installed in host computer.

[0041] Reference is made to Figures 1 to 9 The accessory 10 of the first embodiment of the utility model is provided.The accessory 10 includes mounting seat 100 and air nozzle body 200.

[0042] The mounting seat 100 has mounting interface 110.The host computer can be provided with host computer interface for mechanical connection with the mounting interface 110, and the mounting seat 100 is connected to the host computer by the mounting interface 110 and the host computer interface.

[0043] In the embodiment, mechanical connection is used between the mounting interface 110 and the host computer interface, such as clamping structure, which can stably connect the accessory 10 to the host computer, and the accessory 10 is not easy to fall off during use.

[0044] In combinationFigure 2 、 Figure 3 The air nozzle body 200 has an air inlet end 330, an air outlet end 320, and an air outlet channel 300 between the air inlet end 330 and the air outlet end 320. The air nozzle body 200 is rotatably connected to the mounting base 100 through the air inlet end 330. The air outlet end 320 of the air nozzle body 200 can be provided with an air outlet 310.

[0045] The mounting base 100 can have an air duct in communication with the air outlet channel 300. Air flow in the main machine passes through the air duct of the mounting base 100 and the air outlet channel 300 in the air nozzle body 200, and is blown out through the air outlet 310.

[0046] In a specific embodiment, the accessory 10 is a styling air nozzle accessory, and the air outlet 310 can be flat.

[0047] In an embodiment, the air nozzle body 200 can rotate 360° relative to the mounting base 100, and a plurality of mounting positions can be arranged at intervals in the rotation direction of the air nozzle body 200, and the air nozzle body 200 can be rotated to any mounting position. When the air nozzle body 200 is in different mounting positions, the air outlet direction of the air outlet 310 is different. In this way, the user can rotate the air nozzle body 200 according to the use requirement, and quickly adjust the air outlet direction of the air outlet 310.

[0048] Referring to Figures 3 to 5 One of the mounting base 100 and the air nozzle body 200 is provided with a positioning member 120, and the other is provided with a plurality of positioning grooves 130 arranged along the rotation direction of the air nozzle body 200. The positioning member 120 can extend towards the positioning grooves 130 or retract away from the positioning grooves 130, so as to cooperate with at least one positioning groove 130 after the air nozzle body 200 is rotated into position.

[0049] In the embodiment, the positioning member 120 is an elastic positioning member. The positioning member 120 has a cooperation state cooperating with the positioning groove 130 and a non-cooperation state not cooperating with the positioning groove 130, and the elastic force of the positioning member 120 in the cooperation state is smaller than the elastic force in the non-cooperation state.

[0050] In a specific embodiment, the plurality of positioning grooves 130 are arranged on the mounting base 100, and the positioning member 120 is arranged on the air nozzle body 200. The plurality of positioning grooves 130 are arranged at intervals along the rotation direction of the air nozzle body 200. The positioning member 120 can be provided with two groups, and the two groups of positioning members 120 can be symmetrically arranged relative to the rotation axis X of the air nozzle body 200, thereby improving the stability of the overall structure. At the same time, it is also possible to provide a more uniform resistance, and the user can obtain a better hand feeling when rotating the air nozzle body 200.

[0051] Each positioning groove 130 corresponds to an installation position, when the positioning member 120 is matched with any positioning groove 130, the tuyere body 200 is rotated to the position. When the user rotates the tuyere body 200, the positioning member 120 is rotated, so that the positioning member 120 is disengaged from the cooperation with one positioning groove 130, and the positioning member 120 is rotated to cooperate with other positioning grooves 130.

[0052] When the positioning member 120 is disengaged from the cooperation with the positioning groove 130, the positioning member 120 is compressed to accumulate elastic force, when the positioning member 120 moves to cooperate with the positioning groove 130, the elastic force of the positioning member 120 is released. Thus, when the user rotates the tuyere body 200, the user can be provided with the clear tactile feedback of the jerk, through the cooperation design of the positioning groove 130 and the positioning member 120, the user can clearly feel that the tuyere body 200 is accurately switched between the multiple installation positions, or the change of the different installation positions, so as to prompt the user to rotate the amplitude, and ensure that the user has clear operation feeling and accurate control when adjusting the wind direction.

[0053] In addition, since the elastic force of the positioning member 120 in the cooperation state with the positioning groove 130 is smaller than the elastic force of the positioning member 120 in the non-cooperation state with the positioning groove 130, the user needs to overcome the elastic force of the positioning member 120 to compress the positioning member 120, so as to rotate the tuyere body 200. Therefore, the cooperation of the positioning member 120 and the positioning groove 130 can have a limiting effect, to a certain extent, limit the rotation of the tuyere body 200 relative to the mounting seat 100, avoid the unexpected rotation of the tuyere body 200 relative to the mounting seat 100 in the use process, affect the user experience, also help to prevent the user from causing the inaccurate position of the tuyere body 200 due to improper operation, thereby improving the usability and reliability of the product.

[0054] In an embodiment of the utility model, the positioning member 120 includes a spring and a positioning bead 121, when the positioning member 120 is in the cooperation state, the positioning bead 121 is partially located in the positioning groove 130. When the user rotates the tuyere body 200, the positioning bead 121 can be taken out from the positioning groove 130, at this time, the spring is compressed, and the elastic force of the spring is increased. When the positioning bead 121 is rotated to the cooperation position with another positioning groove 130, the elastic force of the spring is released, and the positioning bead 121 is partially inserted into the positioning groove 130. The positioning bead 121 is spherical, can be smoothly cooperated with or disengaged from the cooperation with the positioning groove 130, and is convenient for the user to easily rotate the tuyere body 200. The appropriate friction and elastic force between the positioning member 120 and the positioning groove 130 make the rotation process of the tuyere body 200 smooth and have moderate damping feeling, avoid the too loose or too tight situation.

[0055] In summary, the accessory 10 for the hair dryer provided by the embodiment can be stably connected with the main machine and is not easy to fall off from the main machine during use. On the other hand, the user can rotate the air outlet body 200 according to the use requirement to adjust the air outlet direction. In addition, the positioning member 120 and the positioning groove 130 are arranged to limit the rotation of the air outlet body 200 relative to the mounting seat 100 to a certain extent, thereby improving the stability of the product and providing tactile feedback for the user, so that the user can accurately control the direction of the air outlet, and the user experience is better.

[0056] Further, referring to Figures 2 to 4 In the embodiment of the utility model, one of the mounting seat 100 and the air outlet body 200 is provided with a connecting groove 111 extending along the rotation direction of the air outlet body 200, and the other is provided with a connecting rib 211 matched with the connecting groove 111, and the connecting rib 211 can rotate along the connecting groove 111.

[0057] In the embodiment, the connecting groove 111 is arranged on the mounting seat 100 and located on the side of the mounting seat 100 close to the air outlet end 320. The connecting rib 211 can be arranged on the air outlet body 200. During assembly, the air outlet body 200 and the mounting seat 100 can be inserted and assembled, so that the connecting rib 211 is clamped into the connecting groove 111.

[0058] The matching of the connecting groove 111 and the connecting rib 211 can limit the relative movement of the mounting seat 100 and the air outlet body 200 along the rotation axis X of the air outlet body 200 and perpendicular to the rotation axis X, so that the air outlet body 200 can only rotate relative to the mounting seat 100. That is, the air outlet body 200 and the mounting seat 100 can be connected and rotated through the connecting groove 111 and the connecting rib 211, and the whole assembly process is simple, without the need for additional complex connecting structure, so as to realize the stable connection of the air outlet body 200 and the mounting seat 100.

[0059] Further, in the embodiment, the mounting seat 100 has a connecting wall 140 protruding towards the air outlet end 320, and the connecting groove 111 or the connecting rib 211 is arranged on the connecting wall 140.

[0060] Specifically, in the embodiment, the connecting groove 111 is arranged on the connecting wall 140, and the connecting rib 211 is arranged on the air outlet body 200. Of course, the connecting rib 211 can also be arranged on the connecting wall 140, and the connecting groove 111 is arranged on the air outlet body 200.

[0061] In an embodiment, the connecting walls 140 are arranged at intervals along the rotation direction of the nozzle body 200. In this way, the connecting walls 140 are more likely to be elastically deformed, facilitating the assembly process of the connecting rib 211 being inserted into the connecting groove 111, and enabling the nozzle body 200 to be quickly and rotatably connected to the mounting base 100.

[0062] In an embodiment, the nozzle body 200 further comprises an assembly seat 240 for mounting the positioning member 120, the assembly seat 240 is arranged adjacent to the connecting wall 140 along the rotation axis X, and the positioning groove 130 is concavely formed from one end of the connecting wall 140 adjacent to the assembly seat 240, and the extension direction of the positioning member 120 is parallel to the rotation axis X of the nozzle body 200.

[0063] In the embodiment, the opening direction of the positioning groove 130 is towards the assembly seat 240. In the assembly process, the positioning member 120 can be mounted to the assembly seat 240 first, and then the mounting base 100 and the nozzle body 200 are inserted and assembled. The insertion direction of the mounting base 100 and the nozzle body 200 is parallel to the rotation axis X. In the assembly process, when the connecting rib 211 is inserted into the connecting groove 111, the positioning member 120 is located at a cooperation position cooperating with the positioning groove 130 or a non-cooperation position not cooperating with the positioning groove 130. At this time, if the positioning member 120 and the positioning groove 130 are in cooperation, i.e., the positioning member 120 is partially located in the positioning groove 130, the user can directly use the accessory for the hair dryer; if the positioning member 120 and the positioning groove 130 are in non-cooperation, i.e., the positioning member 120 is located between two positioning grooves 130, the user only needs to rotate the nozzle body 200 to make the positioning member 120 enter the positioning groove 130. In the assembly process, the positioning member 120 and the positioning groove 130 do not need to be additionally positioned, the extension direction of the positioning member 120 is the same as the insertion direction of the mounting base 100 and the nozzle body 200, and in the assembly process, a large elastic force does not need to be overcome, and the overall assembly process is simple and fast.

[0064] Further, in an embodiment of the utility model, at least part of the positioning grooves 130 are concavely formed through the connecting wall 140, so as to divide the connecting wall 140 into multiple segments along the rotation direction of the nozzle body 200.

[0065] In the embodiment, the positioning groove 130 can be used for cooperating with the positioning member 120, and can also divide the connecting wall 140 to make the connecting rib 211 and the connecting groove 111 easily connected, so as to simplify the overall manufacturing process and reduce the overall size.

[0066] Further, continuing to refer to Figure 2 , Figure 3 , Figures 5 to 9 In an embodiment of the utility model, the nozzle body 200 comprises an inner shell 210, and the air outlet channel 300 can be formed in the inner shell 210.

[0067] The tuyere body 200 can further include an end shell 230. The end shell 230 can be sleeved on the outside of the inner shell 210 close to the air inlet end 330.

[0068] The connecting rib 211 or the connecting groove 111 on the tuyere body 200 is arranged on the radial outside of the inner shell 210 or the radial inside of the end shell 230.

[0069] The mounting seat 240 is arranged on the inner shell 210 and located between the inner wall surface of the end shell 230 and the outer wall surface of the inner shell 210 in the radial direction of the inner shell 210.

[0070] Specifically, in the embodiment, the radial inside of the end shell 230 is provided with the connecting rib 211, that is, the connecting rib 211 protrudes to the inside of the end shell 230 in the radial direction. The outer surface of the inner shell 210 is provided with the mounting seat 240, and the end shell 230 can shield the positioning member 120, so that the accessory 10 has a better appearance. The end shell 230 is annular, and a rib or a textured structure can be arranged on the outer surface of the end shell 230, and the user can rotate the tuyere body 200 by rotating the end shell 230. The arrangement of the end shell 230 provides the user with a better operation structure for rotating the tuyere body 200, thereby improving the comfort of use of the user.

[0071] In an embodiment of the utility model, the tuyere body 200 further includes an outer shell 220. The outer shell 220 is sleeved on the outside of the inner shell 210. The outer shell 220, the inner shell 210 and the end shell 230 are fixedly connected and jointly form the tuyere body 200.

[0078] Continuing to refer to Figures 1 to 3 In an embodiment, the outer shell 220 and the inner shell 210 form an airflow passage 250 therebetween, and the airflow passage 250 has a large internal cross section or multiple airflow passages, which helps to promote airflow and heat dissipation. The outer shell 220 has a first air port 221 and a second air port 222 communicating the airflow passage 250 with the outside of the outer shell 220, so that the accessory 10 can quickly remove the heat around the inner shell 210 through the airflow during operation, avoiding excessive temperature of the inner shell.

[0079] In this embodiment, during use of the accessory 10, the airflow in the hair dryer main machine is continuously blown out from the air outlet passage 300. After a certain period of use, the temperature of the inner shell 210 will rise, causing the inner shell 210 to become hot, affecting the user's use. By sleeving the outer shell 220 outside the inner shell 210, the transmission of the temperature of the inner shell 210 to the outside can be isolated. This technical solution ensures that the user will not feel uncomfortable due to the high temperature of the inner shell 210 during long-term use through the design of thermal isolation and airflow cooling. Even under high temperature conditions, the outer shell 220 can effectively reduce the surface temperature of the air nozzle, preventing burns or discomfort caused by overheating of the inner shell. The effective cooling of the airflow not only improves the comfort of the user, but also enhances the safety of the product.

[0080] In addition, the temperature of the air nozzle body 200 is increased, and a pressure difference can exist between the inside of the airflow channel 250 and the external environment, thereby facilitating the flow of fluid in the airflow channel 250 through the first air port 221 and the second air port 222, dissipating heat from the air nozzle body 200, avoiding excessively high temperature of the air nozzle body 200, and providing a more comfortable use experience, so that the user does not have to worry about discomfort or injury due to overheating of the air nozzle.

[0081] Further, in an embodiment of the present application, the first air port 221 and the second air port 222 are arranged on the side of the shell 220 close to the air inlet end 330. At the air outlet end 320 of the air nozzle body 200, the airflow channel 250 between the shell 220 and the inner shell 210 is closed.

[0082] In the present embodiment, the air outlet end 320 of the inner shell 210 is provided with a turned-up edge 216 facing the shell 220, and the inner surface of the shell 220 is provided with a step close to the air outlet end 320, and the turned-up edge 216 of the inner shell 210 is lapped on the step, thereby closing the airflow channel 250 between the air outlet end 320 of the shell 220 and the air outlet end 320 of the inner shell 210. At the same time, the lapping of the turned-up edge 216 on the step can also achieve the limiting of the shell 220 and the inner shell 210. During installation, the airflow channel between the air outlet end of the shell 220 and the air outlet end of the inner shell 210 can be closed by sleeving the shell 220 on the outer side of the inner shell 210 along the rotation axis X direction.

[0083] In this way, the airflow in the airflow channel 250 can better flow between the first air port 221 and the second air port 222.

[0084] At the air inlet end 330, the inner shell 210 is inserted into the mounting seat 100, and a sealing ring 218 is arranged between the inner shell 210 and the mounting seat 100 to seal the gap between the inner shell 210 and the mounting seat 100. In this way, the airflow blown by the host computer can be prevented from entering the airflow channel 250 between the inner shell 210 and the shell 220, thereby affecting the blowing effect.

[0085] In the present embodiment, the air inlet end 330 of the inner shell 210 is provided with a groove, and the sealing ring 218 is installed in the groove. The inner surface of the mounting seat 100 is provided with a limiting boss 112, and the air inlet end 330 of the inner shell 210 protrudes outside the shell 220 and partially protrudes into the mounting seat 100, abutting against the limiting boss 112. The sealing ring 218 can seal the gap between the inner shell 210 and the limiting boss 112, thereby preventing the airflow blown by the host computer from entering the airflow channel 250 between the inner shell 210 and the shell 220.

[0086] Preferably, the first air port 221 and the second air port 222 are symmetrically arranged relative to the rotation axis X of the tuyere body 200. In this way, the air flow can directly pass through the first air port 221 and the second air port 222, forming a convection, and the heat dissipation effect is better.

[0087] Specifically, referring to Figure 7 In the embodiment, the inner shell 210 includes a first part 214 arranged at the air inlet end 330 and a second part 215 arranged at the air outlet end 320. The first part 214 is tapered from the air inlet end 330 to the air outlet end 320, and the second part 215 is flat. The second part 215 has opposite first and second flat walls 2151 and 2152. The second part 215 has a flat air outlet 310.

[0088] The outer shell 220 can have a shape similar to that of the inner shell 210. The first air port 221 and the second air port 222 can be arranged on both sides of the outer shell 220 along the length direction of the flat air outlet 310. The air flow flowing through the first air port 221 and the second air port 222 can directly flow through the first and second flat walls 2151 and 2152, thereby carrying away more heat and having a better heat dissipation effect.

[0089] Further, referring to Figure 7 and Figure 9 In an embodiment of the utility model, the inner surface of the outer shell 220 is provided with a first clamping structure 223, and the outer surface of the inner shell 210 is provided with a second clamping structure 213 matched with the first clamping structure 223. The first clamping structure 223 and the second clamping structure 213 are arranged close to the air outlet end 320.

[0090] By clamping the first clamping structure 223 and the second clamping structure 213, the mechanical strength of the inner shell 210 and the outer shell 220 can be enhanced, deformation of the inner shell 210 and the outer shell 220 can be avoided, and the connection stability between the inner shell 210 and the outer shell 220 can be increased.

[0091] Further, continuing to refer to Figure 2 、 Figure 3 In an embodiment of the utility model, the inner shell 210 is provided with a guide vane 260. The guide vane 260 is connected to the first and second flat walls 2151 and 2152.

[0092] In this embodiment, on the one hand, the guide vane 260 can serve as a reinforcing rib to reduce the risk of deformation of the inner shell 210, improve the mechanical strength of the inner shell 210, and maintain the stability of the entire accessory. On the other hand, the guide vane 260 can be arranged obliquely to guide the flow direction of the fluid in the air outlet channel 300, so that the air blown out of the air outlet channel 300 is more concentrated and stable to the target area. The guide vane 260 can reduce the dispersion of airflow, so that the airflow is more concentrated and uniform at the air outlet, thereby improving the concentration of wind speed and wind force, and reducing the turbulence of airflow, making the airflow flow out more smoothly and orderly, avoiding problems such as uneven wind force and unstable wind direction, and ensuring that the user can obtain a more uniform and comfortable airflow experience during use.

[0093] Further, in an embodiment of the utility model, the mounting seat 100 is also provided with an accessory detection element, and the accessory detection element comprises a magnet 270.

[0094] In this embodiment, the magnet 270 can be provided with one or more, which can be designed according to the detection requirements. When the accessory 10 includes a plurality of different types of accessories 10, the magnet 270 can have multiple. The number of magnets 270 in different accessories 10 is the same, but the magnetic pole arrangement can be different. For example, the accessory detection element includes four magnets, the magnetic pole arrangement of the A-type accessory close to the air inlet end 330 side can be N-pole, the magnetic pole arrangement of the B-type accessory close to the air inlet end 330 side can be S-pole, and the magnetic pole arrangement of the C-type accessory close to the air inlet end 330 side can be N-pole, S-pole, N-pole and S-pole arranged alternately.

[0095] The host is provided with a Hall sensor for detecting the magnetic force information of the magnet 270, and the magnetic force information of the magnet 270 is detected by the Hall sensor when the accessory 10 is installed on the host. The magnetic force information corresponding to the magnet 270 arranged in different ways is different, so the type of the accessory 10 can be judged according to the detected magnetic force information. The controller can also be provided in the host, which can automatically control the air volume and temperature according to the type of the accessory 10, and improve the user experience.

[0096] In this embodiment, the mounting seat 100 can include an interface part, a detection element mounting part and a connecting part. In the direction of the rotating axis X of the accessory 10, the interface part, the detection element mounting part and the connecting part can be arranged in sequence from the air inlet end 330 to the air outlet end 321. The interface part can be provided with a mounting interface 110 for connecting with the host. The connecting part has a connecting wall 140 for rotating connection with the air nozzle body 200. The detection element mounting part can protrude outward relative to the interface part for mounting the detection element.

[0097] The magnet 270 and the Hall sensor are not in physical contact, thus no mechanical wear is generated, and no interference is generated to the mechanical connection structure of the accessory 10 and the main machine, because any mechanical connection structure can be used to connect the accessory 10 and the main machine, and the accessory 10 is not easy to fall off from the main machine.
