Description

Technical Field

[0001] This utility model relates to the field of hair dryers, and more specifically to a hair dryer with uniform airflow. Background Technology

[0002] Most hair dryers currently feature a hollow shaft, meaning the internal part of the shaft has a first air duct with a first air outlet. The hollow section forms a second air duct, with a second air outlet and a second air inlet at each end. The second air duct relies on negative pressure to draw airflow from the second air inlet to the second air outlet, supplementing the airflow at the first air outlet. However, the airflow in the first air duct flows and gathers radially from bottom to top before exiting through the first air outlet. This results in less airflow at the top of the shaft compared to the bottom, and the supplementary airflow from the second air duct also tends to concentrate at the bottom, failing to effectively supplement the airflow at the top. Consequently, the hair dryer experiences uneven airflow and a poor user experience. Utility Model Content

[0003] To address the aforementioned technical problems, the purpose of this utility model is to provide a hair dryer with uniform airflow. A guide component is provided in the second air duct, which connects the bottom of the second air inlet and the top of the second air outlet. This allows the natural airflow from the second air inlet to converge towards the top of the second air outlet through the guide component, enabling the second air duct to better supplement the airflow at the top of the hair dryer, resulting in a more uniform and comfortable airflow.

[0004] To achieve the above objectives, this utility model provides a hair dryer with uniform airflow, including a blower casing, a heating wire assembly, and a handle. The blower casing has a first air duct and a second air duct. The first air duct is disposed outside the second air duct, and a first air outlet is provided at one end of the first air duct. The second air duct is axially connected and has a second air outlet and a second air inlet. A guide member is provided inside the second air duct, and the guide member connects the bottom of the second air inlet and the top of the second air outlet. Natural air from the second air inlet can be gathered towards the top of the second air outlet through the guide member. The heating wire assembly is installed inside the first air duct. The handle has a placement cavity, which is connected to the first air duct. A drive motor is provided inside the placement cavity.

[0005] In some embodiments, the guide element is disposed below the second air duct, causing the central axis of the second air outlet to be offset upward. The guide element includes a first guide surface that extends arc-shaped from the second air inlet along the axial direction of the second air duct toward the top of the second air outlet.

[0006] In some implementations, the central axis of the second air duct is offset upwards by 10-20 mm.

[0007] In some embodiments, a second guide surface is also included, which is disposed on the side of the first guide surface near the second air outlet. The second guide surface is disposed along the axial direction of the second air duct, so that the airflow passing through the second guide surface is disposed in the same direction as the airflow of the first air outlet.

[0008] In some embodiments, a third guide surface is also included, which is disposed on the side of the first guide surface near the second air inlet. The third guide surface is disposed along the radial direction of the second air duct, and the first guide surface connects the second guide surface and the third guide surface by arc.

[0009] In some embodiments, the air guide is further provided with a third air duct, which is suitable for installing maintenance components. The top of the third air duct is also provided with a third air outlet, which is connected to the second air duct.

[0010] In some embodiments, the third air outlet is disposed at the connection between the first guide surface and the second guide surface, the third air outlet is disposed in the same direction as the second air outlet, and the third guide surface is also provided with a third air inlet.

[0011] In some embodiments, an auxiliary motor is also provided in the third air duct, and the auxiliary motor is connected to the third air inlet and the third air outlet.

[0012] In some embodiments, the bottom of the air guide is further provided with a fourth air inlet, which is connected to the first air duct, so that the airflow at the bottom of the first air duct enters the second air duct through the third air duct and flows out from the top of the air duct.

[0013] In some embodiments, the guide element is disposed at the top of the second air duct, an auxiliary motor is provided inside the guide element, and a third air inlet and a third air outlet are provided at both ends of the guide element along the axial direction. The third air inlet is connected to the second air duct, and the third air outlet is arranged in the same direction as the first air outlet.

[0029] refer to Figure 1 and Figure 2 This utility model provides a hair dryer with uniform airflow, including a blower 1, a heating wire assembly, and a handle. The blower 1 has a first air duct 11 and a second air duct 12. The first air duct 11 is located outside the second air duct 12. One end of the first air duct 11 has a first air outlet. The second air duct 12 is axially connected and has a second air outlet and a second air inlet. A guide 2 is provided inside the second air duct 12. The guide 2 is connected to the bottom of the second air inlet and the top of the second air outlet. Natural air from the second air inlet can be gathered towards the top of the second air outlet through the guide 2. The heating wire assembly is installed inside the first air duct 11. The handle has a placement cavity that is connected to the first air duct 11. A drive motor is provided inside the placement cavity.

[0030] In this embodiment, a guide 2 is provided in the second air duct 12. The guide 2 is connected to the bottom of the second air inlet and the top of the second air outlet, so that the natural wind from the second air inlet can be gathered to the top of the second air outlet through the guide 2. This allows the second air duct 12 to better supplement the airflow at the top of the blower 1, making the airflow of the blower more uniform and more comfortable.

[0031] Specifically, the air duct 1 has a first air duct 11 and a second air duct 12. The first air duct 11 has a first air outlet at one end and a first air inlet at the connection between the air duct 1 and the handle. The drive motor blows air into the first air duct 11 through the first air inlet and out through the first air outlet. The second air duct 12 is located inside the first air duct 11. The second air duct 12 has a second air inlet and a second air outlet at both ends along its axial direction. The second air outlet is aligned with the first air outlet. After airflow is blown out from the first air outlet of the first air duct 11, a negative pressure is created at the second air outlet, causing external airflow to flow from the second air inlet to the second air outlet, supplementing and strengthening the airflow at the first air outlet. A guide member 2 is provided inside the second air duct 12, connecting the bottom of the second air inlet and the top of the second air outlet. Natural airflow from the second air inlet can gather towards the top of the air duct 1 through the guide member 2, making the airflow at the first air outlet more uniform.

[0032] Furthermore, the guide element 2 is disposed below the second air duct 12, causing the central axis of the second air outlet to shift upward. The guide element 2 includes a first guide surface 21, which extends arc-shaped from the second air inlet along the axial direction of the second air duct 12 toward the top of the second air outlet.

[0033] In this embodiment, the guide member 2 is disposed below the second air duct 12 and the top of the guide member 2 is provided with a first guide surface 21, so that the central axis of the second air outlet is offset upward, and the airflow of the second air duct 12 can gather towards the top of the second air outlet through the first guide surface 21.

[0034] Specifically, the central axis of the second air duct 12 is offset upwards by 10-20mm. Preferably, the central axis of the second air duct 12 is offset upwards by 15mm. The guide member 2 is arranged along the axial direction of the second air duct 12. A first guide surface 21 is provided at one end of the guide member 2 near the second air inlet. The first guide surface 21 is curved and extends from the second air inlet along the axial direction of the second air duct 12 towards the top of the second air outlet. The curved end of the first guide surface 21 is flush with the axial direction of the second air duct 12. It is worth noting that the first guide surface 21 extends from the middle of the second air inlet along the axial direction of the second air duct 12 towards the top of the second air outlet. The first guide surface 21 is a convex curved surface, not a concave curved surface. That is, the starting point of the first guide surface 21 is connected to the curvature of the second air inlet. Preferably, the starting point of the first guide surface 21 is tangential to the second air inlet.

[0035] Furthermore, it also includes a second guide surface 22, which is disposed on the side of the first guide surface 21 near the second air outlet. The second guide surface 22 is disposed along the axial direction of the second air duct 12, so that the airflow passing through the second guide surface 22 is disposed in the same direction as the airflow of the first air outlet.

[0036] In this embodiment, the second guide surface 22 is disposed on the side of the first guide surface 21 near the second air outlet. The second guide surface 22 is disposed along the axial direction of the second air duct 12, so that the airflow of the second air duct 12 passing through the second guide surface 22 is disposed in the same direction as the airflow of the first air outlet, thereby avoiding the airflow of the second air duct 12 from colliding with the airflow of the first air duct 11, which would damage the airflow and cause great noise.

[0037] Specifically, it also includes a second guide surface 22, which is disposed on the side of the first guide surface 21 near the second air inlet. The second guide surface 22 is arranged radially along the second air duct 12, and the first guide surface 21 is arc-connected to the second guide surface 22. The second guide surface 22 is flush with the second air inlet, and the arc-connection of the first guide surface 21 to the second guide surface 22 allows the airflow from the second air inlet to converge towards the top of the second air duct 12 via the second guide surface 22. The converged airflow then flows axially along the second air duct 12 and exits from the second air outlet via the second guide surface 22. It is worth noting that a fourth guide surface can also be provided on the left and right sides of the guide component 2. The fourth guide surface is arc-shaped, allowing the airflow from the second air duct 12 to reach the bottom of the second air outlet more quickly, thereby enhancing the airflow of the blower.

[0038] Furthermore, the guide component 2 is also provided with a third air duct, which is suitable for installing maintenance components. The top of the third air duct is also provided with a third air outlet, which is connected to the second air duct 12.

[0039] In this embodiment, a third air duct is provided inside the air guide 2, and the third air duct is suitable for setting up maintenance components, making full use of the space inside the air guide 2 and improving the user experience.

[0040] Specifically, the third air outlet is located at the junction of the first guide surface 21 and the second guide surface 22. The third air outlet is arranged in the same direction as the second air outlet. The second guide surface 22 is also provided with a third air inlet.

[0041] It is worth noting that an auxiliary motor is also installed in the third air duct, which is connected to the third air inlet and the third air outlet.

[0042] In a modified embodiment, the bottom of the guide member 2 is also provided with a fourth air inlet, which is connected to the first air duct 11, so that the airflow at the bottom of the first air duct 11 enters the second air duct 12 through the third air duct and flows out from the top of the air duct 1.

[0043] In this embodiment, the guide 2 connects the first air duct 11 and the third air duct, so that the hot air in the first air duct 11 can pass through the third air duct and then reach the second air duct 12 through the third air duct, thereby achieving uniformity of air output from the air duct 1.

[0044] In another modified embodiment, the guide 2 is disposed at the top of the second air duct 12, the guide 2 is provided with an auxiliary motor, and the guide 2 has a third air inlet and a third air outlet at both ends along the axial direction. The third air inlet is connected to the second air duct 12, and the third air outlet is arranged in the same direction as the first air outlet.

[0045] In this embodiment, the guide 2 is disposed at the top of the second air duct 12, and an auxiliary motor is provided inside the guide 2. The auxiliary motor can quickly and efficiently blow the airflow from the third air inlet to the third air outlet and supplement and strengthen the airflow at the top of the air duct 1.

[0046] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
