[0037] This utility model provides a hair dryer 100, which can be configured as a hair dryer, hand dryer, or dryer. The hair dryer 100 generates a hot airflow for drying hair, clothing, shoes, hats, etc. For ease of explanation, the following description will primarily use a hair dryer as an example to illustrate the specific structure of the hair dryer 100; other devices can be adapted accordingly.

[0038] Specifically, please refer to Figures 1 to 2 In this embodiment, the blower device 100 includes a housing 1, a circuit structure 2, a suction structure 3, a heating structure 4, and an air outlet grille 5. The housing 1 is cylindrical and has an air inlet 14 and an air outlet 15. The air outlet 15 is located on the peripheral side of the housing 1. The circuit structure 2, the suction structure 3, and the heating structure 4 are all located inside the housing 1 and are arranged sequentially along the axial direction of the housing 1. The circuit structure 2 is located at the air inlet end of the suction structure 3, and the heating structure 4 is located at the air outlet end of the suction structure 3. After the airflow enters the housing 1 through the air inlet 14, it flows sequentially through the circuit structure 2, the suction structure 3, and the heating structure 4 before being discharged from the air outlet 15. The air outlet grille 5 is detachably mounted on the housing 1 and communicates with the air outlet 15.

[0039] In this embodiment, the housing 1 is cylindrical, and preferably closed at both ends. An air inlet 14 and an air outlet 15 are provided on the housing 1. When the blower 100 is turned on, airflow enters the housing 1 through the air inlet 14. Under the action of the suction device, the airflow flows sequentially through the circuit structure 2, the suction structure 3, and the heating structure 4. This allows cold airflow to pass through the circuit structure 2, improving its heat dissipation, and also enhances the heating efficiency of the heating structure 4. Furthermore, the air outlet 15 is located on the peripheral surface of the housing 1. When using the hair dryer 100, the axial direction of the housing 1 can be arranged in the vertical direction, so that the air outlet 15 can be better oriented towards the user. Moreover, since the circuit structure 2, the suction structure 3, and the heating structure 4 are arranged sequentially along the axial direction of the housing 1, the center of gravity of each component can be better overlapped when the hair dryer 100 is in use, making it easier for the user to hold and use the hair dryer 100. Furthermore, an air outlet grille 5 is provided at the air outlet 15, and the airflow can be evenly distributed through the air outlet grille 5, making the airflow gentler and more even when blowing onto the user's hair, thus effectively improving the user experience.

[0040] Among them, such as Figure 1As shown, the housing 1 has a first end and a second end arranged opposite to each other along its axial direction. An air outlet 15 is located at the first end of the housing 1, and an air inlet 14 is located at the second end of the housing 1. The air inlet 14 can be located on the peripheral surface of the housing 1 and / or the end face of the second end of the housing 1 to ensure sufficient airflow. The shape of the air outlet 15 is not specifically limited; for example, the air inlet 14 can be circular, square, or irregularly shaped. Preferably, the shape of the air outlet 15 is adapted to the surface shape of the housing 1, and is elliptical, so that the air outlet area can be larger and the air outlet effect better.

[0041] The circuit structure 2 includes a circuit board and a circuit board mounting bracket. The circuit board mounting bracket is a hollow annular frame that supports and fixes the circuit board in the middle of the bracket. The surface of the circuit board is aligned with the axial direction of the housing 1, allowing the cold airflow entering the housing 1 through the air inlet 14 to flow better along the surface of the circuit board. The circuit board effectively guides the airflow towards the suction structure 3, improving heat dissipation for the circuit board. The circuit structure 2 is electrically connected to both the suction structure 3 and the heating structure 4, providing power to and controlling their operation. The suction structure 3 can be configured as a fan, with its inlet facing the circuit board and its outlet facing the heating structure 4. The heating structure 4 includes a ring-shaped heating wire. Airflow passing through the gap formed by the heating wire is heated, and the resulting hot airflow is blown out through the air outlet 15 for user use.

[0042] The air outlet grille 5 is used to guide and divert the airflow, making the airflow gentler. To facilitate the assembly and disassembly of the air outlet grille 5, a fastening part 54 is provided on the air outlet grille 5, and a snap-fit ​​part 62 is provided inside the housing 1. The fastening part 54 can extend into the housing 1 through the air outlet 15 and engage with the snap-fit ​​part 62, so that the air outlet grille 5 is fixed to the housing 1 by the snap-fit ​​part 62 and the fastening part 54, facilitating the cleaning and maintenance of the air outlet grille 5.

[0043] In one embodiment, combined with Figure 3 and Figure 4As shown, the air outlet grille 5 covers the air outlet 15. The air outlet grille 5 includes a grille frame 51 and multiple grille ribs 52 disposed on the inner ring side of the grille frame 51. The multiple grille ribs 52 are arranged at intervals along the axial direction of the housing 1. The fastening part 54 includes a snap-fit ​​groove 541 protruding from the side of the grille frame 51 facing the housing 1. The snap-fit ​​part 62 includes a snap-fit ​​protrusion 621 disposed on the inner side of the housing 1. The snap-fit ​​protrusion 621 engages with the snap-fit ​​groove 541. By directly guiding and separating the airflow of the air outlet 15, the air outlet grille 5 is made smaller, thus making it easier to replace.

[0044] In another embodiment, combined Figure 5 and Figure 6 As shown, the air outlet grille 5 forms part of the housing 1, and the air outlet 15 is provided on the air outlet grille 5, so that after the air outlet grille 5 is removed, the housing 1 can be better matched with different accessories (such as straightening combs), making the connection operation more convenient, and making the hair dryer 100 better adaptable to a variety of accessories.

[0045] Specifically, the housing 1 includes a main body with a clearance notch at one end along its axial direction; the air outlet grille 5 includes a cover 53 covering the clearance notch, an air outlet 15 on the cover 53, and a plurality of grille ribs 52 inside the air outlet 15; a snap-fit ​​groove 541 protrudes from the inside of the cover 53, and a snap-fit ​​part 62 snaps onto a protrusion 621 on the inside of the housing 1, the protrusion 621 engaging with the snap-fit ​​groove 541. Similarly, the air outlet grille 5 can be quickly assembled and disassembled using the protrusion 621 and the groove 541, making the operation simple and convenient, and requiring fewer assembly parts.

[0046] Preferably, such as Figure 4 and Figure 5 As shown, multiple snap-fit ​​grooves 541 are provided, and the multiple snap-fit ​​grooves 541 surround the outer periphery of the multiple grid ribs 52, making the air outlet of the blower 100 more stable and less prone to shaking under the action of airflow.

[0047] Furthermore, the blower 100 also includes an air guide 6 disposed within the housing 1. The air guide 6 forms an air guide channel that connects the air outlet of the heating structure 4 and the air outlet 15. Through this guide channel, airflow flowing axially along the housing 1 can be guided to flow radially along the housing 1, allowing for better exit from the air outlet 15, resulting in less wind resistance and higher airflow efficiency. The snap-fit ​​part 62 is disposed on the air guide 6 and is connected to the air outlet grille 5, simultaneously fixing both the air outlet grille 5 and the air guide 6 to the housing 1, making the assembly of the blower 100 simpler and more convenient.

[0048] Preferably, combined with Figure 2 and Figure 3 As shown, the air guide 6 includes an air guide duct 61, which has a first opening 64 along the axial direction of the housing 1 and a second opening 65 along the radial direction of the housing 1. The first opening 64 is connected to the air outlet of the heating structure 4, and at least a portion of the second opening 65 is inserted into the air outlet 15 and connected to the air outlet grille 5. The air guide duct allows for better airflow reversal and reduces airflow resistance, ensuring a good airflow rate even during reversal.

[0049] Furthermore, multiple fastening portions 54 are provided, and multiple snap-fit ​​portions 62 are provided in a one-to-one correspondence with the fastening portions 54; wherein, when the air outlet grille 5 is disposed over the air outlet 15, the housing 1 is provided with a flange 12 on the inner circumference of the hole corresponding to the air outlet 15, and the flange 12 is provided with multiple guide holes 13, and the multiple snap-fit ​​portions 62 can pass through the multiple guide holes 13 one-to-one and snap-fit ​​with the multiple fastening portions 54 one-to-one. The multiple guide holes 13 can restrict the position of the air outlet grille 5 and the air guide 6 along the plane direction of the air outlet 15, making the installation of the air outlet grille 5 and the air guide 6 more stable and easier to align during installation.

[0050] Preferably, the first end of the housing 1 along its axial direction is arc-shaped. When the blower 100 is in normal use, the first end is the upper end of the housing 1, which is cylindrical. The air guide 61 is arranged in an arc shape to match the first end of the housing 1. This allows the airflow to flow towards the air outlet 15 more effectively along the inner surface of the air guide 6 under the guidance of the air guide 6. Furthermore, a limiting groove 63 protrudes from the outer side of the air guide 61, and a limiting post 11 is provided on the inner side of the housing 1. The limiting post 11 is engaged within the limiting groove 63 to restrict the circumferential displacement of the air guide 61 along the first end of the housing 1, preventing the air guide 6 from rotating relative to the housing 1 after it is fixed, thus making the fixing of the air guide 6 more stable.

[0051] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
