Description

Technical Field

[0001] This utility model relates to the field of hair dryer motor technology, and in particular to a novel hair dryer motor. Background Technology

[0002] Among the many components of a hair dryer, the air duct motor, as the core component for realizing the blowing function, plays a crucial role as its performance and structural design directly determine the overall efficiency and service life of the machine. Chinese utility model patent CN218183177U discloses the specific structure of a high-speed hair dryer brushless motor. This motor is vertically mounted, with the air duct housing vertically fitted onto the upper end of the motor, the top of the motor extending to the top of the air duct housing, and the fan wheel horizontally fitted onto the top of the air duct housing and connected to the top of the motor. While this design is compact and helps reduce the overall size of the machine, the air duct housing directly covers the outside of the motor, forming a relatively enclosed space. This makes it difficult for the large amount of heat generated by the motor during high-speed operation to dissipate effectively, resulting in obstructed heat dissipation channels, severe heat accumulation, and thus affecting the motor's operational stability and leading to poor overall heat dissipation performance. Prolonged high-temperature operation can also accelerate motor aging and even pose safety hazards. To address this problem, we propose a novel hair dryer motor. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a new type of hair dryer motor.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A novel hair dryer motor includes a moving part, a stator part, and a stator frame. The stator part is fixedly disposed on the stator frame, and the moving part is rotatably disposed at the center position of the stator frame. It also includes a duct housing for mounting the stator frame. The duct housing includes an outer ring housing portion and an inner ring housing portion. A duct portion is provided between the outer ring housing portion and the inner ring housing portion. A bearing housing portion is provided at the front end of the inner cavity of the inner ring housing portion. Four connecting portions are provided between the inner ring housing portion and the bearing housing portion at equal intervals. An arc-shaped heat dissipation hole is provided between two adjacent connecting portions. A wall groove communicating with the arc-shaped heat dissipation hole is opened at the bearing housing portion.

[0005] To further elaborate, the bearing support portion is located between the two wall slots of the bearing seat, and each of the arc-shaped heat dissipation holes is provided with a corresponding wall slot.

[0006] To elaborate further, the width of the arc-shaped heat dissipation hole is L1, and the width of the wall groove at the bearing seat is L2, where L1 > L2 and L1 < 2*L2.

[0007] To further elaborate, the stator is connected to the rotating shaft, and a rolling bearing is sleeved on the rotating shaft. The rolling bearing is rotatably mounted on the bearing seat portion of the air duct housing.

[0008] To further elaborate, the stator is connected to one end of the rotating shaft, the other end of the rotating shaft is connected to the impeller, and the rolling bearing is disposed between the impeller and the stator.

[0009] To elaborate further, the outer ring seat of the air duct housing is installed in the inner cavity of the outer shell.

[0010] The beneficial effects of this utility model are as follows: This utility model adopts a special structural design for the air duct housing, with a connecting part between the inner ring housing and the bearing housing, and an arc-shaped heat dissipation hole between two adjacent connecting parts. A wall groove connected to the arc-shaped heat dissipation hole is opened at the bearing housing.

[0018] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0019] Specific Implementation Example 1: Combined with Appendix Figure 1 To be continued Figure 3 As shown, a novel hair dryer motor includes a mover 20, a stator 30, and a stator frame 40. The stator 30 is fixedly mounted on the stator frame 40, and the mover 20 is rotatably mounted at the center of the stator frame 40. It also includes a duct housing 10 for mounting the stator frame 40. The stator 30 is connected to a rotating shaft 50, and a rolling bearing 60 is fitted onto the rotating shaft 50. The rolling bearing 60 is rotatably mounted on the bearing seat 14 of the duct housing 10. The stator 30 is connected to one end of the rotating shaft 50, and the other end of the rotating shaft 50 is connected to an impeller 70. The rolling bearing 60 is located between the impeller 70 and the stator 30.

[0020] Combined with appendix Figure 4 To be continued Figure 6 As shown, the air duct housing 10 includes an outer ring seat 11 and an inner ring seat 12, with an air duct 13 located between the outer ring seat 11 and the inner ring seat 12. The outer ring seat 11 of the air duct housing 10 is installed in the inner cavity of the outer casing 80. When the stator 30 drives the impeller 70 to rotate via the rotating shaft 50, the back of the impeller 70 draws air from the air duct portion 13 of the air duct housing 10 and then blows the drawn air out in the forward direction. Simultaneously with the rotation of the impeller 70, the rolling bearing 60 also rotates synchronously. During rotation, the rolling bearing 60 rubs against the bearing seat portion 14 of the air duct housing 10, generating heat. This heat accumulation is severe, affecting the working stability of the motor and resulting in poor overall heat dissipation performance.

[0021] Combined with appendix Figure 4 To be continued Figure 6 As shown, the inner ring seat 12 has a bearing seat 14 at its front end. Four equally spaced connecting portions 15 are provided between the inner ring seat 12 and the bearing seat 14. An arc-shaped heat dissipation hole 16 is provided between adjacent connecting portions 15. A wall groove 17 communicating with the arc-shaped heat dissipation hole 16 is provided at the bearing seat 14. When the impeller 70 rotates, it absorbs heat through the arc-shaped heat dissipation hole 16, and the hot air at the bearing seat 14 of the air duct housing 10 is discharged by the impeller 70 through the arc-shaped heat dissipation hole 16. Furthermore, through the structural design of the wall groove 17, the hot air generated by the rotation of the moving part 20 can be guided to the arc-shaped heat dissipation hole 16 and discharged by the impeller 70.

[0022] Specific Implementation Example 2: Combined with Appendix Figure 1 To be continued Figure 3 As shown, a novel hair dryer motor includes a moving part 20, a stator part 30, and a stator frame 40. The stator part 30 is fixedly mounted on the stator frame 40, and the moving part 20 is rotatably mounted at the center of the stator frame 40. It also includes a duct housing 10 for mounting the stator frame 40. Figure 4 To be continued Figure 6As shown, the air duct housing 10 includes an outer ring seat portion 11 and an inner ring seat portion 12. An air duct portion 13 is provided between the outer ring seat portion 11 and the inner ring seat portion 12. The outer ring seat portion 11 of the air duct housing 10 is installed in the inner cavity of the outer shell 80. A bearing seat portion 14 is provided at the front end of the inner cavity of the inner ring seat portion 12. Four connecting portions 15 are provided between the inner ring seat portion 12 and the bearing seat portion 14 at equal intervals. An arc-shaped heat dissipation hole 16 is provided between two adjacent connecting portions 15. A wall groove 17 communicating with the arc-shaped heat dissipation hole 16 is opened at the bearing seat portion 14.

[0023] Combined with appendix Figure 4 To be continued Figure 6 As shown, the bearing support portion 18 is located between the two wall slots 17 of the bearing housing portion 14, and each arc-shaped heat dissipation hole 16 is provided with a corresponding wall slot 17. The width of the arc-shaped heat dissipation hole 16 is L1, and the width of the wall slot 17 at the bearing housing portion 14 is L2, where L1 > L2 and L1 < 2*L2. This structural design, where L1 > L2 and L1 < 2*L2, not only avoids poor heat dissipation efficiency due to the arc-shaped heat dissipation hole 16 being too small, but also balances the size relationship between the arc-shaped heat dissipation hole 16 and the wall slot 17, avoiding the problem that the bearing housing portion 14 of the air duct housing 10 cannot effectively support the rolling bearing 60 due to the wall slot 17 being too large.

[0024] When the impeller 70 rotates, it can absorb heat through the arc-shaped heat dissipation holes 16, and the hot air at the bearing seat 14 of the air duct housing 10 is discharged by the impeller 70 through the arc-shaped heat dissipation holes 16. In addition, through the structural design of the wall slot 17, the hot air generated by the rotation of the moving part 20 can be guided to the arc-shaped heat dissipation holes 16 and discharged by the impeller 70.

[0025] The stator 30 is connected to the rotating shaft 50, and a rolling bearing 60 is fitted onto the rotating shaft 50. The rolling bearing 60 is rotatably mounted on the bearing seat 14 of the air duct housing 10. The stator 30 is connected to one end of the rotating shaft 50, and the other end of the rotating shaft 50 is connected to the impeller 70. The rolling bearing 60 is located between the impeller 70 and the stator 30.
