[0022] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] Please refer to the appendix carefully. Figure 1-6The new type of hair clipper with digital display mainly includes an upper shell 1, a lower shell 2, air duct accessories 3, a cover 4, a digital display window 5, an electrical control circuit board 6, a protective net 7, a blade motor shell 8, a blade motor cover 9, a blade motor 10, an eccentric shaft 11, a hair clipper head 12, a circuit board bracket 13, a fan motor shell 14, a circuit board inner shell 15, a fan motor cover 16, a battery 17, a fan motor 18, a suction fan blade 19, and a switch 20. The upper shell 1 is equipped with a digital display window 5, which is positioned directly opposite the digital display component on the internal electrical control circuit board 6, allowing users to easily read device information in real time.

[0024] In use, the upper shell 1 and lower shell 2 are fastened together to form a main cavity, inside which are housed a blade motor assembly, a fan motor assembly, and an air duct accessory 3. The air duct accessory 3 covers the interior of the lower shell 2, and the cavity between the air duct accessory 3 and the lower shell 2 forms an air intake channel. A protective mesh 7 is provided at the air inlet of the air duct accessory 3 to effectively prevent hair clippings and other foreign objects from being sucked into the air duct, thus avoiding channel blockage. The blade motor assembly is located at the front end of the lower shell 2 and includes a blade motor housing 8, a blade motor cover 9, a blade motor 10, and an eccentric shaft 11. The eccentric shaft 11 is located on the output shaft of the blade motor 10 and connects to the hair clipper head 12, providing it with power. The blade motor 10 is housed inside the blade motor housing 8, and the blade motor cover 9 is encapsulated at the rear of the blade motor housing 8. Waterproof sealing rings are provided at the blade motor penetration point and the joint position of the blade motor cover 9, thus forming a sealed protective cavity inside the blade motor housing 8. This structure effectively prevents water from entering and thus protects the motor from damage.

[0025] The fan motor assembly is located above the air duct accessory 3 and includes a circuit board bracket 13, a fan motor housing 14, a circuit board inner housing 15, a fan motor cover 16, an electrical control circuit board 6, a battery 17, a fan motor 18, and a suction fan blade 19. The circuit board bracket 13 has a battery compartment below to accommodate the battery 17 and a mounting slot above for installing the electrical control circuit board 6. The fan motor 18 is housed in the cavity at the rear of the fan motor housing 14, and its output shaft connects to the suction fan blade 19, which forms an effective airflow channel directly opposite the air outlet of the air duct accessory 3. The assembly employs a multi-layered sealing design, with waterproof sealing rings at the junction of the circuit board inner housing 15 and the fan motor housing 14, the connection point of the fan motor cover 16, and the point where the fan motor shaft passes through. These together form a sealed protective cavity inside the fan motor housing 14, reliably protecting the internal electronic components and motor from liquid corrosion. The lower housing 2 has an array of air outlet holes around the suction fan blade 19 to ensure efficient airflow discharge. The top of the upper shell 1 is fastened with a cover 4 via a snap-fit ​​mechanism, forming a hair storage compartment between the two. Sliding the cover 4 completely exposes the hair storage space, making hair removal operations simpler and more thorough.

[0026] In addition, the digital display window 5 is provided with a switch hole for installing a switch 20 to control the start and stop of the equipment.

[0027] In this application: When the hair clipper is turned on, the eccentric shaft on the blade motor assembly drives the hair clipper blade to move at high speed to complete the hair cutting operation. At the same time, the fan motor starts, driving the suction fan blades to rotate at high speed, generating negative pressure airflow in the suction channel formed by the air duct accessories and the lower shell.

[0028] The shed hair is then drawn into the hair storage chamber by the negative pressure airflow. After initial filtration by a protective mesh, the airflow is efficiently discharged through an array of air outlets around the lower casing. During this process, a digital display window on the upper casing, facing the digital display component 21 on the electrical control circuit board, displays key parameters such as device power, operating level, and usage time in real time. Users can monitor the device's operating status in real time, greatly improving ease of use and controllability.

[0029] By setting a digital display window on the upper shell, an intuitive human-machine interface is created, which can display key equipment operating parameters such as battery level, speed level, and working time in real time, enabling users to clearly control the equipment status and significantly improving product usability and user experience.
