[0037] The utility model provides a hair dryer 100, specifically, please refer to Figures 1 to 3In this embodiment, the hair dryer 100 includes a main body 1, a handle 2 and a heating component 3, the main body 1 is provided with an air outlet 11; the handle 2 is provided on one side of the main body 1 along its circumference and is provided with an air inlet 21, and a first through hole 4 is provided at the junction of the handle 2 and the main body 1, the first through hole 4 connects the air inlet 21 and the air outlet 11; the heating component 3 is provided in the main body 1; wherein the orthographic projection of the heating component 3 on the plane where the first through hole 4 is located at least partially overlaps with the first through hole 4.

[0038] In this embodiment, an air outlet 11 is provided on the main body 1, and the air outlet 11 is used to face the surface to be blown (such as hair, animal hair or wet cloth, etc.), and an air inlet 21 is provided on the handle 2, and the handle 2 and the main body 1 are connected through a first through hole 4. The air flow can enter the handle 2 from the air inlet 21 of the hair dryer 100, flow through the first through hole 4 and then enter the main body 1, and then flow out through the air outlet 11 after being heated by the heating component 3, so as to form a hot air flow blowing towards the hair dryer 100; and the heating component 3 is arranged in the The orthographic projection on the plane where the first through hole 4 is located at least partially overlaps with the first through hole 4, so that the airflow can be blown directly to the heating component 3 after flowing out of the handle part 2, so that the flow path of the airflow between the handle part 2 and the heating component 3 is shorter, so the airflow can be quickly heated after entering the main body 1, the heating efficiency is higher, and the air outlet efficiency of the blower is also higher; and the shorter flow path can make the overall structure of the hair dryer 100 more compact and smaller in size, which can better meet the user's demand for the use of a miniaturized hair dryer 100.

[0039] For the convenience of explanation, the hair dryer 100 is mainly used to dry the user's hair. Figure 1 and Figure 2As shown, the central axis of the main body 1 is perpendicular to the central axis of the handle 2. The main body 1 is roughly cylindrical, and the air outlet 11 is located at the axial front end of the main body 1. The handle 2 is also roughly cylindrical. The main body 1 and the handle 2 are arranged in a roughly "T" or "L" shape. The handle 2 is arranged close to the rear end of the main body 1. When the user touches the handle 2, the air outlet 11 can be better oriented towards the user, making it easier to hold. The front end here refers to the end of the main body 1 facing the user when the hair dryer 100 is in normal use, which is the front end and the end of the main body 1 facing away from the user is the rear end. Among them, the handle part 2 is open at one end facing the main body part 1, and the first through hole 4 is formed on the peripheral side of the main body part 1, so that the main body part 1 and the handle part 2 are connected. The air flow can enter the handle part 2 from the air inlet 21 on the handle part 2, and flow into the main body part 1 from the first through hole 4, and then be heated by the heating component 3 and blown out from the air outlet 11 to form a hot air flow to dry the hair.

[0040] Further preferably, the heating component 3 is also arranged in a roughly circular shape, and the heating component 3 and the main body 1 are coaxially arranged, so that the distance between the heating component 3 and the inner wall of the main body 1 is more uniform, thereby avoiding local overheating of the main body 1. At the same time, the heating component 3 can more evenly heat the airflow entering the main body 1, so that the hot airflow blown out is also more evenly distributed, thereby providing a better hair blowing experience.

[0041] Specifically, combined Figure 3 and Figure 4 As shown, the heating component 3 includes a heating bracket 31 and a heating wire 32. The heating bracket 31 is disposed within the main body 1 and defines an inner cavity. The heating bracket 31 is used to secure the heating wire 32 within the main body 1 while preventing the heating wire 32 from directly contacting the peripheral sidewalls of the main body 1, thereby preventing the main body 1 from overheating and potentially scalding the user. A second through-hole 3111 is formed on the heating bracket 31, communicating with the first through-hole 4. The inner cavity of the heating bracket 31 connects the second through-hole 3111 with the air outlet 11. The heating wire 32 is disposed within the inner cavity of the heating bracket 31. When air enters the main body 1 from the first through-hole 4, it can enter the inner cavity of the heating bracket 31 through the second through-hole 3111, where it is then heated by the heating wire 32. The heating bracket 31 also conducts the airflow entering the main body 1, allowing it to flow more effectively through the heating wire 32, ensuring a better heating effect.

[0042] The heating wire 32 includes a winding frame and a heating wire wound on the winding frame. The winding frame is connected and fixed to the heating bracket 31 to fix the heating wire in the inner cavity of the heating bracket 31. Figure 4 and Figure 5 As shown, the heating bracket 31 includes a ring-shaped side bracket 311 and a center bracket 312 located at one end of the side bracket 311 near the air outlet 11. The heating wire 32 is sleeved inside the side bracket 311 and connected to the center bracket 312. A first air passage is formed at the connection between the side bracket 311 and the center bracket 312. A second air passage is formed on the winding frame of the heating wire 32 along the axial direction of the main body 1. The first air passage connects the air outlet 11 and the second air passage. After airflow enters the inner cavity of the heating bracket 31 through the second through-hole 3111, it enters the second air passage. The heating wire is wound around the circumference of the second air passage. As airflow passes through the second air passage, it is heated by the heating wire and flows from the first air passage toward the air outlet 11.

[0043] Specifically, combined Figure 4 and Figure 6 As shown, the center bracket 312 is recessed toward the inside of the side bracket 311, forming a bowl-shaped structure. The heating wire 32 includes an inner ring portion 321 and an outer ring portion 322 that are nested together. The heating wire is located on at least one of the inner ring portion 321 and the outer ring portion 322. The second airflow channel is formed between the inner ring portion 321 and the outer ring portion 322. The outer ring portion 322 is sleeved around the inner circumference of the side bracket 311, and the center bracket 312 is secured to the inner side of the inner ring portion 321. The center bracket 312 is provided with a plurality of studs, and the inner ring portion 321 of the winding frame is provided with a plurality of screws. The center bracket 312 and the inner ring portion 321 are screwed into the corresponding studs and screw holes to secure the heating wire 32 to the heating bracket 31, ensuring the stability of the heating wire 32.

[0044] In order to ensure that the airflow can be heated more quickly after entering the main body 1, preferably, the orthographic projection of the first through hole 4 on the heating component 3 is completely located within the heating component 3. That is, the first through hole 4 is arranged directly opposite the heating component 3. After passing through the first through hole 4, the airflow can flow directly to the heating component 3, that is, enter the inner cavity of the heating bracket 31, and be heated by the heating wire 32. No guide air duct is required between the handle 2 and the heating component 3, the airflow conduction path is shortened, and the heating efficiency is also higher, which can effectively improve the working efficiency of the hair dryer 100.

[0045] Further preferably, the orthographic projection of the second through hole 3111 on the plane where the first through hole 4 is located at least partially overlaps with the second through hole 3111, so that the airflow can better enter the inner cavity of the heating bracket 31 from the second through hole 3111 after passing through the first through hole 4, thereby achieving heating of the airflow, less wind resistance encountered by the airflow, and higher working efficiency of the hair dryer 100.

[0046] There are a plurality of second through holes 3111 , and the plurality of second through holes 3111 are spaced apart along the circumference of the side bracket 311 , so that the air flow speed entering the inner cavity of the heating bracket 31 is faster.

[0047] Moreover, combined Figure 2 and Figure 3 As shown, the hair dryer 100 further includes a circuit board 5 disposed within the main body 1. The circuit board 5 is electrically connected to the heating component 3 to control the operation of the heating component 3. The circuit board 5 is located outside the second air passage and on the side of the heating component 3 facing away from the air outlet 11. This allows the airflow to flow toward the air outlet 11 after entering the heating component 3, thereby preventing the temperature of the circuit board 5 from rising and better protecting the circuit board 5.

[0048] Understandable, combined Figure 2 and Figure 3As shown, the hair dryer 100 also includes an airflow generating device 6. The air inlet 21 is located at the end of the handle portion 2 away from the main body 1. A first airflow channel is formed between the air inlet 21 and the first through-hole 4, and the airflow generating device 6 is located in the first airflow channel. The airflow generating device 6 can be set as an axial flow fan or a centrifugal fan. The airflow generating device 6 forms a negative pressure in the handle portion 2. Under the action of the negative pressure, the airflow outside the hair dryer 100 can enter the handle portion 2 from the air inlet 21 and blow from the air outlet end of the airflow generating device 6 to the heating component 3 in the main body 1 to form a hot airflow that blows towards the user's hair, thereby better drying the hair. The airflow generating device 6 is also electrically connected to the circuit board 5. The circuit board 5 can better control the operation of the airflow generating device 6 to realize the operation or pause of the hair dryer 100, or to realize the control of the airflow size, so that the user can use more diverse functions.

[0049] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention.
