Description
Hair dryer housing and hollow hair dryer
[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on January 12, 2024, with application number 202420087186.8 and invention name “A hair dryer housing and a hollow hair dryer”, the entire contents of which are incorporated by reference into this application. Technical Field
[0002] The present application relates to the technical field of hair care, and in particular to a hair dryer housing and a hollow hair dryer. Background Art
[0003] Existing hair dryer housings typically feature an air inlet at the rear and an outlet at the front. The housing is a solid structure, forming an internal air duct extending from the inlet to the outlet. If the rear end of the housing is used as the air inlet, the suction force at the inlet is strong, often causing the air to stick to the hair, affecting the user's hair drying experience.
[0004] Therefore, it is necessary to improve the existing hair dryer to solve the problem that the suction force at the air inlet is too strong, which easily affects the user experience by absorbing foreign objects such as hair.
[0005] The above information disclosed in this Background section is included only for enhancement of understanding of the background of the disclosure and therefore it may contain information that does not form the prior art that is currently known to a person of ordinary skill in the art.
[0006] Summary of the Invention
[0007] One purpose of the present application is to provide a hair dryer housing and a hollow hair dryer, which can effectively solve the problem that the suction force at the air inlet of the existing hair dryer is too large, which easily affects the user experience due to the absorption of foreign objects such as hair.
[0008] To achieve the above objectives, on the one hand, the present application provides a hair dryer housing and a hollow hair dryer, comprising:
[0009] A hollow shell, wherein the hollow shell surrounds an inner shell space, and the hollow shell is provided with a plurality of hollow holes connecting the inner shell space to the hair dryer housing and the outer space of the hollow hair dryer;
[0010] An internal bracket, the internal bracket is located in the space inside the shell and surrounds and forms an internal air duct;
[0011] Wherein, the internal bracket also includes an air inlet connecting the internal air duct to the space inside the shell and an air outlet connecting the internal air duct to the hair dryer shell and the external space of the hollow hair dryer.
[0012] Optionally, the air inlet is located on a circumferential surface of one end of the internal bracket.
[0013] Optionally, the air outlet is located at the end surface of the other end of the internal bracket.
[0014] Optionally, an air inlet grille is installed at the air inlet.
[0015] Optionally, the circumferential surface of the hollow shell is provided with a positioning slot extending in the axial direction;
[0016] The internal bracket is provided with a guide boss which is pluggably connected to the positioning slot along the axial direction.
[0017] Optionally, a side surface of the guide boss is provided with a limiting slot for the hollow shell to be snapped into.
[0018] On the other hand, a hollow hair dryer is provided, comprising:
[0019] Any of the above hair dryer housings;
[0020] The fan assembly is installed in the internal bracket of the hair dryer housing and is used to drive the air outside the hair dryer housing to flow through the hollow hole, the space inside the shell, the air inlet, the internal air duct, and the air outlet in sequence.
[0021] Optionally, the fan assembly is installed inside the internal air duct, or the fan assembly is installed at the air outlet.
[0022] Optionally, it also includes a hair dryer handle hingedly connected to the internal bracket.
[0023] Optionally, it also includes a light strip assembly.
[0024] The light strip assembly is arranged at at least one position of the front end of the hair dryer housing, the rear end of the hair dryer housing, and between the hair dryer housing and the internal bracket.
[0025] The beneficial effects of the present application are: providing a hair dryer housing and a hollow hair dryer. When hair is to be blown, the air outlet is directed toward the hair and the blower assembly is activated. Air from the hair dryer housing flows sequentially through the hollow holes, the housing interior, the air inlet, the internal air duct, and the air outlet, finally blowing toward the hair. During this process, the air inlet is a secondary air inlet structure, while the hollow holes are a primary air inlet structure. The hollow holes are distributed throughout the hair dryer housing, resulting in a large overall hollow area and a weaker adsorption force. Therefore, foreign objects such as hair or tissues are not easily adsorbed. Furthermore, the housing interior space between the hollow holes and the air inlet acts as a buffer, further reducing the suction force of the hollow holes.
[0026] Therefore, the hair dryer housing and hollow hair dryer provided in the present application can effectively solve the problem that the suction force at the air inlet of the existing hair dryer is too large, which easily affects the user experience due to the absorption of foreign objects such as hair.

However, these embodiments do not limit the present application, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are included within the scope of protection of the present application.
[0038] The present application provides a hair dryer housing and a hollow hair dryer, which are suitable for application scenarios of blowing hair. They can effectively solve the problem that the suction force at the air inlet of the existing hair dryer is too large, which easily affects the user experience due to the adsorption of foreign objects such as hair.
[0039] Example 1
[0040] 1 , the hollow hair dryer provided in this embodiment includes a hair dryer housing 100 , a fan assembly 200 , and a hair dryer handle 300 .
[0041] Referring to Figure 2 , the hair dryer housing 100 comprises a hollow outer shell 1 and an internal support 2. The hollow outer shell 1 encloses an inner shell space 101 and is provided with a plurality of hollow holes 102 that connect the inner shell space 101 to the hair dryer housing 100 and the outer space of the hollow hair dryer. The internal support 2 is located within the inner shell space 101 and encloses an internal air duct 204.
[0042] The internal bracket 2 further includes an air inlet 201 connecting the internal air duct 204 to the shell space 101 and an air outlet 202 connecting the internal air duct 204 to the hair dryer shell 100 and the external space of the hollow hair dryer.
[0043] In this embodiment, the fan assembly 200 is installed in the internal bracket 2 of the hair dryer housing 100. For example, the fan assembly 200 is installed inside the internal air duct 204, or the fan assembly 200 is installed at the air outlet 202, and is used to drive the air outside the hair dryer housing 100 to flow through the hollow hole 102, the space inside the shell 101, the air inlet 201, the internal air duct 204, and the air outlet 202 in sequence.
[0044] Optionally, the air inlet 201 is located on the circumferential surface of one end of the internal bracket 2 , and the air outlet 202 is located on the end surface of the other end of the internal bracket 2 .
[0045] When blowing hair, aim the air outlet 202 at the hair and start the blower assembly 200. Air from the hair dryer housing 100 flows sequentially through the hollow holes 102, the housing interior space 101, the air inlet 201, the internal air duct 204, and the air outlet 202, before finally blowing toward the hair. During this process, the air inlet 201 represents the secondary air inlet structure, while the hollow holes 102 represent the primary air inlet structure. The hollow holes 102 are distributed throughout the hair dryer housing 100, resulting in a relatively large hollow area and a relatively weak suction force. Therefore, they are less likely to attract foreign objects such as hair or tissues. Furthermore, the housing interior space 101 acts as a buffer between the hollow holes 102 and the air inlet 201, further reducing the suction force of the hollow holes 102.
[0046] Therefore, the hair dryer housing 100 and the hollow hair dryer provided in the present application can effectively solve the problem that the suction force at the air inlet 201 of the existing hair dryer is too strong, which easily affects the user experience due to the absorption of foreign objects such as hair.
[0047] Optionally, an air inlet grille 3 (the mesh size of the air inlet grille 3 is smaller than the size of the hollow hole 102 ) is installed at the air inlet 201 to prevent tiny foreign objects or mosquitoes and the like from entering the internal air duct 204 .
[0048] Referring to Figures 2 and 3 , the circumferential surface of the hollow housing 1 is provided with an axially extending positioning slot 103. The internal bracket 2 is provided with a guide boss 203 that is axially pluggably connected to the positioning slot 103. The side of the guide boss 203 is provided with a retaining groove 2031 for the hollow housing 1 to engage. The internal bracket 2 can be inserted into the hollow housing along the axial direction.
[0049] Furthermore, the bottom of the guide boss 203 of the internal bracket 2 extends downward and is hingedly connected to the hair dryer handle 300 for easy gripping.
[0050] Optionally, the hollow hair dryer further includes a light strip assembly. In this embodiment, the light strip assembly is disposed between the hair dryer housing 100 and the internal bracket 2. When the light strip assembly is illuminated, light can be emitted outward through the hollow holes 102, creating a gorgeous lighting effect. Of course, in some other embodiments, the light strip assembly is also disposed at the front end of the hair dryer housing 100, the rear end of the hair dryer housing 100, or at least one position between the hair dryer housing 100 and the internal bracket 2. This application is not limited to this.
[0051] In summary, the hair dryer housing 100 and the hollow hair dryer provided in this embodiment have the following advantages:
[0052] ① The air inlet 201 belongs to the second air inlet structure, and the hollow hole 102 is the first air inlet structure. The hollow holes 102 are distributed throughout the hair dryer housing 100. The overall hollow area is large, and the adsorption force it can generate is weak. Therefore, it is not easy to adsorb foreign objects such as hair or paper towels;
[0053] ② The hollow shell and the internal bracket 2 are plug-in connected, which is convenient for assembly and helps improve production efficiency;
[0054] ③ The hollow shell is covered with hollow holes 102. After the light strip assembly is set inside, a gorgeous lighting effect can be produced;
[0055] ④The air intake method has been changed from the traditional end of the handle to the current body air intake method, which adopts a fully hollowed-out large area to absorb sufficient air input. Visually, the fully hollowed-out body is integrated with the whole machine, and can also achieve a hidden air intake effect.

During this process, the air inlet 201 represents the secondary air inlet structure, while the hollow holes 102 represent the primary air inlet structure. The hollow holes 102 are distributed throughout the hair dryer housing 100, resulting in a relatively large hollow area and a relatively weak suction force. Therefore, they are less likely to attract foreign objects such as hair or tissues. Furthermore, the housing interior space 101 acts as a buffer between the hollow holes 102 and the air inlet 201, further reducing the suction force of the hollow holes 102.
[0063] Therefore, the hair dryer housing 100 and the hollow hair dryer provided in the present application can effectively solve the problem that the suction force at the air inlet 201 of the existing hair dryer is too strong, which easily affects the user experience due to the absorption of foreign objects such as hair.
[0064] Optionally, an air inlet grille 3 (the mesh size of the air inlet grille 3 is smaller than the size of the hollow hole 102 ) is installed at the air inlet 201 to prevent tiny foreign objects or mosquitoes and the like from entering the internal air duct 204 .
[0065] Optionally, the hollow hair dryer further includes a light strip assembly. In this embodiment, the light strip assembly is disposed between the hair dryer housing 100 and the internal bracket 2. When the light strip assembly is illuminated, light can be emitted outward through the hollow holes 102, creating a gorgeous lighting effect. Of course, in some other embodiments, the light strip assembly is also disposed at the front end of the hair dryer housing 100, the rear end of the hair dryer housing 100, or at least one position between the hair dryer housing 100 and the internal bracket 2. This application is not limited to this.
[0066] In summary, the hair dryer housing 100 and the hollow hair dryer provided in this embodiment have the following advantages:
[0067] ① The air inlet 201 belongs to the second air inlet structure, and the hollow hole 102 is the first air inlet structure. The hollow holes 102 are distributed throughout the hair dryer housing 100. The overall hollow area is large, and the adsorption force it can generate is weak. Therefore, it is not easy to adsorb foreign objects such as hair or paper towels;
