Description

Technical Field

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

[0002] The hair dryer motor is the core power component of the hair dryer. It drives the fan to rotate, thereby generating airflow. The performance of the hair dryer motor directly affects the air volume, wind speed, and overall drying efficiency of the hair dryer.

[0003] When using a hair dryer, hair can easily get into the motor due to the location of the air inlet and the way it is used. Shorter hairs can be expelled through the air duct without affecting the normal operation of the hair dryer. However, longer hairs can easily become entangled in the rotating motor structure, making them difficult to clean and affecting motor performance and user experience. Therefore, those skilled in the art have provided a hair dryer motor structure to solve the problems mentioned in the background art. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see the appendix Figures 1 to 2 As shown, a hair dryer motor structure in this embodiment of the present invention includes a housing 1, a stator and rotor assembly 2 fixed inside the housing 1, an impeller 3 fixedly connected to the output end of the stator and rotor assembly 2, and a plurality of hair cutting assemblies 4 arranged around the outside of the impeller 3.

[0031] The housing 1 includes an outer shell 101, and a plurality of notches 103 are provided around the outer side of the outer shell 101 near the end of the impeller 3;

[0032] The impeller 3 includes a wheel body 31, and multiple blades 32 are fixedly connected to the outer end of the wheel body 31. When the motor of this hair dryer is working, after the stator and rotor assembly 2 is energized, the rotor inside drives the impeller 3 to rotate at high speed, thereby generating airflow. The notch 103 is located on the side close to the impeller 3, so that some of the dust carried by the airflow can be discharged through the notch 103, thereby reducing the amount of dust carried in the airflow. At the same time, when the hair that is wrapped around passes through the notch 103, the notch 103 can cut the hair, thereby reducing the length of the hair and reducing the risk of hair getting tangled in the impeller 3.

[0033] In this embodiment, the outer end of the notch 103 is set to an open state and is U-shaped. The U-shaped notch 103 has a large opening area and is open at one end, which facilitates the discharge of dust and the entry of hair, thereby realizing the function of cutting off the hair.

[0034] Please see Figure 5As shown, in another embodiment of this invention, the notch 103 is configured as a through hole, in the shape of an O. The through hole notch 103 reduces the open area, but compared with the U-shaped notch 103, it has less impact on the structural strength of the shell 1. When it is necessary to ensure the structural strength of the shell 1, the through hole notch 103 can be used.

[0035] It should be noted that the edges of both the U-shaped notch 103 and the O-shaped notch 103 are set at right angles to facilitate cutting off hair strands.

[0036] In this embodiment, an inner shell 102 is fixedly connected to the inner side of the outer shell 101, and the stator and rotor assembly 2 is fixedly connected inside the inner shell 102. An air duct is left between the outer shell 101 and the inner shell 102. The shell 1 adopts a double-layer structure design, and a space is left between the outer shell 101 and the inner shell 102 as an air duct to facilitate the airflow generated by the impeller 3.

[0037] The stator and rotor assembly 2 is electrically connected to a terminal 5 at its outer end. The terminal 5 facilitates power supply. The stator and rotor assembly 2 adopts the stator and rotor structure and wiring method of the existing motor, which will not be described in detail here.

[0038] Example 2

[0039] Please see Figures 1 to 4 As shown, based on Embodiment 1, the hair cutting assembly 4 includes a groove 401 formed on the outer side of the wheel body 31. A movable seat 404 is slidably connected inside the groove 401. A connecting plate 405 is fixed to the outer end of the movable seat 404. A blade 406 is fixedly connected to the outer end of the connecting plate 405. The end of the blade 406 can extend out of the groove 401 and has a cutting edge in the direction of rotation of the impeller 3. The hair cutting assembly 4 will rotate together with the wheel body 31. When the wheel body 31 rotates at high speed, the blade 406 inside the groove 401 will extend out of the groove 401 due to centrifugal force. When the cutting edge of the high-speed rotating blade 406 contacts the hair, it can directly cut the hair, such as the hair wrapped around the blade 32 and the hair located between the blade 32 and the notch 103, thereby further ensuring that the impeller 3 will not be entangled by hair.

[0040] To improve safety and prevent the blade 406 from falling out of the groove 401, a fixed seat 403 is fixedly connected to the center of the groove 401. Two guide rods 408 are fixedly connected to both sides of the upper end face of the fixed seat 403. The movable seat 404 is slidably sleeved between the multiple guide rods 408. The upper end of the guide rods 408 is provided with an outward protrusion. The fixed seat 403 and the guide rods 408 limit the movable seat 404 with the blade 406 connected to it, ensuring that it will not fall out of the groove 401. At the same time, the guide rods 408 can also keep the blade 406 in a stable posture when it is extended, ensuring good hair cutting function.

[0041] In addition, to further improve safety and facilitate installation and maintenance, two tension springs 407 are fixedly connected to the inner bottom of the groove 401. The upper ends of the two tension springs 407 are fixedly connected to the movable seat 404. By setting the tension springs 407, when the motor stops rotating, the blade 406 can be retracted into the groove 401 by the tension of the tension springs 407 and is not exposed, thereby preventing the operator from being scratched during use and maintenance.

[0042] In this embodiment, an outer cover 402 is provided on the outer side of the groove 401. The outer cover 402 is fixedly connected to the groove 401 by multiple screws. The blade 406 is fixedly connected to the connecting plate 405 by screws. A slot is provided at the upper end of the outer cover 402. After the outer cover 402 is closed with the groove 401, the blade 406 can extend out from the slot. The outer cover 402 can protect the internal components of the groove 401, prevent external interference and internal components from flying out, and also facilitate the disassembly and replacement of the blade 406.

[0043] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
