Description

Technical Field

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

[0002] A hair dryer is an appliance primarily used for drying and styling hair. It typically consists of a heating element and a small, high-speed fan. When powered on, the heating element generates heat, and the air blown out by the fan passes over it, becoming hot air. If only the fan is running without the heating element heating up, cold air will be blown out. The fan is driven by a motor, and current motors are noisy during use, and generate significant heat during prolonged operation, affecting their lifespan. Utility Model Content

[0009] Furthermore, the inner housing is provided with multiple fixing grooves, and the stator is provided with fixing protrusions, which are installed in conjunction with the fixing grooves.

[0010] The advantages of adopting the above technical solution are that the fixing groove and the fixing protrusion cooperate with each other to facilitate the fixing of the stator, prevent the stator from rotating and moving, greatly reduce the stator installation error, and facilitate installation.

[0012] Furthermore, the oblique angle is between 60 and 70 degrees.

[0013] The advantage of adopting the above technical solution is that the deflector plate plays a role in guiding the airflow, effectively enhancing the smoothness of the airflow, reducing wind resistance, and lowering noise.

[0014] Furthermore, a siphon port is provided between the bottom of the fixing groove and the stator, and the siphon port connects the gap between the stator and the rotor.

[0015] The advantage of adopting the above technical solution is that, during the rotation of the fan, the generated airflow flows out from the guide channel, which drives the air in the gap between the stator and rotor to flow out from the siphon, thereby playing a role in heat dissipation and extending the service life of the motor.

[0016] Furthermore, the fan includes a fan body and fan blades evenly arranged on the side of the fan body, the fan blades being inclined.

[0017] The advantage of adopting the above technical solution is that when working, the fan blades rotate, generating airflow from the guide channel, which plays a blowing role.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] As shown in Figures 1-2, this utility model discloses a hair dryer motor, including: a housing assembly, a motor assembly, and a fan assembly;

[0031] The motor assembly includes a stator 1 and a rotor 2, wherein the stator 1 is connected to the housing assembly and the rotor 2 is connected to a rotating shaft 3;

[0032] The housing assembly includes an outer shell 4 and an inner shell 5. A plurality of arc-shaped guide plates 6 are provided between the outer shell 4 and the inner shell 5, and a guide channel is formed between the arc-shaped guide plates 6. The motor assembly is installed inside the inner shell 5.

[0033] A fan assembly, including a fan 7, which is connected to the shaft 3.

[0034] The advantages of adopting the above technical solution are that it reduces noise, facilitates heat dissipation, improves motor lifespan, and increases motor efficiency.

[0035] In some implementations, the inner housing 5 is provided with multiple fixing grooves 51, the upper end of the fixing grooves 51 is open and they are evenly distributed around the inner housing 5. The stator 1 is provided with fixing protrusions 11, which are installed in conjunction with the fixing grooves 51, effectively preventing the fixing protrusions 11 and fixing grooves 51 from moving, greatly reducing the installation error of the stator 1 and facilitating installation.

[0036] Furthermore, the end of the guide plate 6 near the fan 7 is flat, and the other end is inclined. The inclined surface forms an angle 61 with the side of the guide plate 6 near the inner shell 5. The angle 61 is between 60 and 70 degrees and protrudes from the upper end of the outer shell 4. The guide plate 6 is arc-shaped as a whole, and multiple guide plates 6 are evenly arranged on the outer surface of the inner shell 5, with a quantity of 4 to 10.

[0037] The advantage of adopting the above technical solution is that the deflector 6 plays a role in guiding the airflow, effectively enhancing the smoothness of the airflow, reducing wind resistance, and lowering noise.

[0038] In some implementations, a siphon 62 is provided between the bottom of the fixing groove 51 and the stator 1. The siphon 62 connects the gap between the stator 1 and the rotor 2. A limiting step is provided on the inner side of the housing to restrict the installation position of the stator 1 and ensure that the siphon 62 is of appropriate size. During the rotation of the fan 7, the generated airflow flows out from the guide channel, driving the air in the gap between the stator 1 and the rotor 2 to flow out from the siphon 62 (airflow path as shown). Figure 3 As shown in the figure, it serves to dissipate heat and extend the service life of the motor.

[0039] Furthermore, the fan 7 includes a fan body 71 and fan blades 72 evenly arranged on the sides of the fan body 71 (e.g., ...). Figure 5 As shown, the fan blades 72 are tilted, and the motor assembly rotates, driving the fan to rotate and thus blowing air.

[0040] Furthermore, the stator 1 includes a stator core 12, a stator support 13, and stator windings (such as...). Figure 4 As shown, the stator bracket 13 is used to fix the stator core 12, and the stator winding is wound around the outside of the stator core 12.

[0041] Furthermore, the upper end of the inner shell 5 is higher than the outer shell 4, and the oblique angle 61 extends beyond the edge of the outer shell 4, extending the air duct, ensuring smooth airflow, and reducing noise.

[0042] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
