[0024] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0025] Reference Figures 1 to 5 A hair dryer includes: a handheld part 1 for a person to hold, and an air outlet 2 connected to the handheld part 1; the air outlet 2 includes a housing 21 detachably connected to the handheld part 1, a front inner housing 22 and a rear inner housing 23 detachably connected to the housing 21, the front inner housing 22 having a plurality of air outlets (not shown in the figure); the front inner housing 22 and the rear inner housing 23 are connected by a first step structure 3.

[0026] When this blower is working, air flows between the outer shell 21 and the front inner shell 22 and the rear inner shell 23, and is blown out through the air outlet. The front inner shell 22 and the rear inner shell 23 are connected by a first step structure 3, so that the front inner shell 22 and the rear inner shell 23 have stable support. The fit of the first step structure 3 can better control the gap between the front inner shell 22 and the rear inner shell 23, reduce the possibility of air leakage from the gap, and ensure the air volume. In the assembly direction, since the front inner shell 22 and the rear inner shell 23 are directly and tightly fitted, the assembly of the sealing ring is reduced, thus reducing the assembly steps of the sealing ring and improving production efficiency.

[0027] Furthermore, the handheld part 1 is equipped with a blower motor, which blows air towards the air outlet 2. The air enters the space between the outer shell 21 and the front inner shell 22 and the rear inner shell 23, and is then blown out through the air outlet.

[0028] Reference Figure 2 and Figure 3 In one embodiment, the first step structure 3 includes a first protrusion 31 disposed on the rear inner shell 23, a first groove 32 disposed adjacent to the first protrusion 31, and a second groove 33 disposed on the front inner shell 22 that matches the first protrusion 31 and a second protrusion 34 that matches the first groove 32, wherein the second protrusion 34 is disposed close to the outer shell 21.

[0029] The second protrusion 34 is located on the side near the outer shell 21, that is, the side near the air outlet path. Even if a small amount of air enters the gap between the second protrusion 34 and the first groove 32 during the air outlet process, it will be rebounded by the first protrusion 31 and flow back, thus ensuring the air outlet volume. Furthermore, during the assembly process, the first protrusion 31 and the second protrusion 34 are in pre-contact, which can play a positioning role. Continuous pushing will make the front inner shell 22 and the rear inner shell 23 completely fit together, further simplifying the assembly steps and improving production efficiency.

[0030] Furthermore, by adopting the first step structure 3 in this embodiment, external dust can be reduced from entering the gap between the front inner shell 22, the rear inner shell 23, and the outer shell 21 through the gap between the second protrusion 34 and the first groove 32, and between the first protrusion 31 and the second groove 33.

[0031] Reference Figure 1 and Figure 2 In one embodiment, the rear inner shell 23 is provided with a mounting cavity 231 and an air inlet 232. The mounting cavity 231 is used for mounting electronic devices. The bracket 4 is detachably connected to the end of the rear inner shell 23 away from the air inlet 232.

[0032] Specifically, the electronic device is a heating element, such as a heating wire, which is existing technology and will not be described here.

[0033] Reference Figure 1 and Figure 2 In one embodiment, a bracket 4 for fixing electronic devices is provided between the outer shell 21 and the front inner shell 22 and the rear inner shell 23. The bracket 4 has a bent portion 41 on the side adjacent to the handheld part 1, and the bent portion 41 bends towards the front inner shell 22. When the air outlet motor is installed in the handheld part 1 and the air outlet direction is towards the air outlet 2, the bent portion 41 can act as a wind deflector to guide the air blown from the motor into the mounting cavity 231. This prevents the air blown from the motor from bypassing the heating element and blowing directly out of the air outlet after leaving the handheld part 1, which would otherwise result in the air not being heated and the drying effect being poor.

[0034] Reference Figure 2 In one embodiment, the first step structure 3 is fitted to the bracket 4.

[0035] When the hair dryer is working, the operation of the motor and the flow of air will generate certain vibrations and forces. These forces and vibrations are transmitted and dispersed through the first step structure 3 and the bracket 4, which may cause gaps or loosening between the front inner shell 22, the rear inner shell 23 and the bracket 4. This can easily cause vibrations and noise when the hair dryer is working, and may even cause the connection between other parts to gradually loosen, affecting the normal use and safety of the hair dryer, and may also shorten the service life of the hair dryer.

[0036] This embodiment further enhances the stability among the front inner shell 22, the rear inner shell 23, and the bracket 4, which helps to improve the mechanical strength and vibration resistance of the air outlet 2 and ensures the stable performance of the hair dryer under long-term use.

[0037] In one embodiment, the bracket 4 engages with the side of the rear inner shell 23 near the outer shell 21.

[0038] During assembly, the heating unit and other electronic components can be installed into the mounting cavity 231 first, and then the bracket 4 can be snapped into the rear inner shell 23 to fix and limit the electronic components; the installation steps are simple and further improve the installation efficiency.

[0039] Reference Figure 2 and Figure 5 In one embodiment, a second step structure 5 is also included, through which the rear inner shell 23 and the outer shell 21 are fitted together.

[0040] The second-stage structure 5 can improve the stability and tightness of the connection between the inner shell 23 and the outer shell 21. During the assembly process, it can achieve rapid positioning and assembly, which helps to improve the assembly quality and further improve production efficiency.

[0041] In one embodiment, the second stepped structure 5 includes a limiting part 51 disposed inside the outer shell 21 and a connecting part 52 disposed on the rear inner shell 23 and matching the limiting part 51. The limiting part 51 and the connecting part 52 cooperate with each other, making the connection between the outer shell 21 and the rear inner shell 23 more precise and secure. Furthermore, the setting of the limiting part 51 and the connecting part 52 can also provide better positioning and fixing functions, preventing the rear inner shell 23 from shifting during installation and reducing the probability of loosening between the rear inner shell 23 and the outer shell 21.

[0042] Reference Figure 1 , Figure 2 and Figure 3In one embodiment, the front inner shell 22 has a guide portion 222 at one end near the outer shell 21. The guide portion 222 is used to assist the front inner shell 22 in being installed into the outer shell 21. In particular, when the front inner shell 22 needs to be assembled with other components, the guide portion 222 can play a guiding and positioning role. When assembling the front inner shell 22, the rear inner shell 23 is first fixedly fitted to the outer shell 21 through the second step structure 5. When installing the front inner shell 22, under the guidance of the guide part 222, the second protrusion 34 and the first protrusion 31 come into contact. Under the guidance of the guide part 222, the front inner shell 22 is continuously pushed towards the rear inner shell 23, so that the second protrusion 34 fits into the first groove 32 and the first protrusion 31 fits into the second groove 33. Even if the second protrusion 34 at the front inner shell 22 has slight deformation, it can still be smoothly fitted and installed with the rear inner shell 23 under the action of the guide part 222, making the installation process smoother and more accurate, reducing assembly time and difficulty, and improving production efficiency.

[0043] Specifically, the guide portion 222 is an inclined surface.

[0044] In one embodiment, a third step structure 6 is also included. The outer shell 21 and the front inner shell 22 are installed through the third step structure 6. The third step structure 6 is used to limit the outer shell 21 and together with the first step structure 3, it holds the front inner shell 22 between the rear inner shell 23 and the outer shell 21, so as to achieve rapid assembly and precise positioning, improve production efficiency and product quality, and facilitate subsequent disassembly and maintenance.

[0045] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
