[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] The utility model provides the following technical solutions:

[0021] As attached Figure 1-4As shown, the utility model discloses a blade device, including a blade 1 and a blade holder 2, wherein the blade 1 is fixed on the blade holder 2, and the blade holder 2 is arranged in an open structure. A plurality of through holes 3 are provided at the center position of the top of the blade holder 2, and the through holes penetrate the center position of the top of the blade holder 2. Specifically, in this design, by providing a through hole 3 at the center position of the top of the blade holder 2, the provision of the through hole 3 can discharge the fallen hair through the through hole 3 during the hair cutting process, thereby effectively avoiding the accumulation of hair on the blade holder 2, keeping the blade 1 device clean and hygienic, and when flushing with water, water can directly pass through, making it very easy to remove hair residues. The weight of the blade head is reduced, and the vibration of the blade head is reduced. In addition, the open structure design of the blade holder 2 makes the replacement and cleaning of the blade 1 more convenient and quick.

[0022] Specifically, through-hole 3 connects to the hair removal groove 13 between the blades 1. This allows hair, after being cut by the blades 1, to flow along the blades 1 into the hair removal groove 13, then from the hair removal groove 13 into through-hole 3, and finally out of the device through through-hole 3. This design not only effectively prevents hair from accumulating and tangling inside the device, but also greatly improves the smoothness and efficiency of trimming. Furthermore, the presence of through-hole 3 serves as a heat dissipation mechanism, ensuring that the device maintains good working condition during extended use and preventing overheating that could damage the motor or other components.

[0023] Furthermore, a blade through hole 12 is provided on the blade, and the area of ​​the blade through hole 12 is ≥0.5²mm. Specifically, in the present embodiment, the area of ​​the blade through hole 12 is set to ≥0.5²mm, and the blade through hole 12 is provided on the blade 1. When each blade 1 is driven by a power source to swing back and forth along the static blade net, each blade 1 will squeeze the air to form an airflow. The power source is a motor. When the speed of the motor is reduced so that the vibration generated by the reciprocating swing of the blade 1 is weakened and is not enough to shake off the broken beard, the airflow can pass through the blade through hole 12 along the reciprocating swing direction of the blade 1, so that a cyclone is formed in the blade groove between adjacent blades 1 to exert additional force on the broken beard to overcome the viscosity of the grease, discharge the broken beard from the blade groove, and improve the discharge efficiency of the broken beard.

[0024] When viewed from either end, the blade holes 12 form an airflow channel 14 that passes through both ends. The airflow channel 14 allows air to flow between the blades 1, effectively cleaning the hair stuck on the blades 1. This design not only improves the working efficiency of the device, but also reduces the maintenance cost caused by hair accumulation.

[0025] Furthermore, a partition block 4 is provided at the top center of the blade holder 2, and the through holes 3 are provided on the partition block 4. The blades 1 are arranged at equal intervals along the length of the blade holder 2, and the through holes 3 on the partition block 4 are provided at a position where the partition block 4 is located between adjacent blades 1. Specifically, in this embodiment, the through holes 3 are provided at a position where the partition block 4 is located between adjacent blades 1, which ensures that the blades 1 remain stable during use and avoids displacement due to vibration or impact. In addition, the location of the through holes 3 can effectively disperse the heat generated during cutting, thereby extending the service life of the blades 1.

[0026] Furthermore, the blade 1 and the blade holder 2 are integrally injection molded, and a blade fixing groove 5 is formed on the separator 4. One end of the blade 1 extends into the blade fixing groove 5 and is fixedly connected to the separator 4. Specifically, in this embodiment, the blade 1 and the blade holder 2 are integrally molded by injection molding. After molding, the blade fixing groove 5 for fixing the blade 1 is formed on the separator 4 of the blade holder 2. The blades 1 located on the separator 4 are respectively inserted into the corresponding blade fixing groove 5 for fixation. This structural arrangement makes the blade 1 more firmly fixed and not easy to loosen or deform.

[0027] Furthermore, a mounting post 6 is provided at the center of the blade holder 2, a power connection hole 7 is provided at the center of the mounting post 6, an upper limit portion 8 and a lower limit portion 9 are provided on the outer wall of the mounting post 6, and a limiting ring groove 10 is formed between the upper limit portion 8 and the lower limit portion 9. Specifically, in this embodiment, the bottom of the blade holder 2 has a power source (not shown) for driving the blade holder 2 to move. The power source is connected to the mounting post 6 on the blade holder 2, and the blade holder 2 is driven to move by the mounting post 6. One end of the mounting post 6 extends into the limiting ring groove 10 and is connected to the mounting post 6. The upper limit portion 8 and the lower limit portion 9 above and below the limiting ring groove 10 can limit the axial position of the power source on the mounting post 6. In this embodiment, the upper limit portion 8 is a ring structure with an arc surface protruding from the mounting column 6, and the lower limit portion 9 is a convex block structure with an inclined surface protruding from the mounting column 6. The inclination direction of the inclined surface is that the outer side of the lower limit portion 9 is inclined toward the inner side of the upper limit portion 8. The setting of the upper limit portion 8 and the lower limit portion 9 can effectively prevent the mounting column 6 from excessive displacement during movement, thereby ensuring the stable operation of the blade holder 2.

[0028] Furthermore, ventilation holes 11 are provided on both sides of the blade holder 2 to connect the inside of the blade holder 2 and the outside of the blade holder 2. Specifically, in this embodiment, the ventilation holes 11 are provided at the lower parts of both sides of the blade holder 2. The provision of the ventilation holes 11 makes it easy to bear the force when removing the blade head, and can also ventilate and discharge hair.

[0029] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
