Abstract

According to the vibrissa knife shearing mechanism, the movable blade is bent, and the cutting edge and the pressure of the elastic piece are located on the same horizontal plane after the movable blade is bent. Therefore, the cutting edge rubs with the static cutter, the cutting edge is most effective by the elastic force of the elastic piece and has no ineffective elastic force. Therefore, the force of the elastic piece is applied to the cutting part of the cutting edge. Therefore, when the same hair is cut, the structure can adopt smaller elastic force. And the pressure of the movable cutter and the static cutter is reduced, so that the abrasion of the movable cutter is reduced, the friction problem of the blades is reduced, the service life is prolonged, and the service time of the machine is prolonged.

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

[0021] As the attachment Figures 1-5The utility model discloses a nose hair scissors cutting mechanism, including static knife 1 and moving blade 4, and moving blade 4 is installed in moving knife support 2 and stretches into static knife 1 and contacts with static knife 1 inner wall, its characterized in that: moving blade 4 sets two pieces, and is opposite and is set up on moving knife support 2, is equipped with elastic member 5 between two piece moving blade 4, and moving blade 4 includes blade part 6 and moving blade body 7, and the sharp edge 8 of blade part 6 is formed, and the both ends of elastic member 5 are respectively abutted moving blade body 7, make the sharp edge 8 on blade part 6 always keep contact with static knife 1 inside, and the sharp edge 8 is in the elastic force direction section range of elastic member 5. Specifically, in the design, by bending moving blade 4, the blade edge after bending and elastic member 5 pressure are on the same horizontal plane. Such blade edge and static knife friction, blade edge receives the elastic force of elastic member 5 most effectively, and there is no invalid elastic force. Such elastic member 5's force all holds in blade edge cutting site. Such cutting same hair, this structure can adopt smaller elastic force. Make moving knife and static knife's pressure smaller, thereby reduced the wear and tear of moving knife, reduced the friction problem of blade, improved the service life, prolonged the machine use time.

[0022] Further, the blade part 6 is formed by bending one side of the moving blade body 7, the sharp edge 8 is formed on the blade part 6, and the angle of the sharp edge 8 is 30-60°. Specifically, in the embodiment, the angle of the sharp edge 8 is preferably 45°. Such design not only ensures the shearing effect, but also reduces the pulling sensation of the nose hair during shearing, thereby improving the user experience. In addition, the sharp edge 8 is finely polished to ensure its sharpness and smoothness, thereby reducing the irritation to the skin. The cooperation between the moving blade 4 and the static knife 1 is tight, and through the continuous elastic force of the elastic member 5, it is ensured that the moving blade 4 can stably adhere to the inner wall of the static knife 1 during the shearing process, thereby realizing precise shearing.

[0023] Further, the sharp edge 8 has a main shearing surface 9, the main shearing surface 9 extends towards one end of the sharp edge 8 to form an end shearing surface 10, the end shearing surface 10 and the main shearing surface 9 have an arc-shaped shearing surface 11 therebetween, and the two sides of the arc-shaped shearing surface 11 are connected with the main shearing surface 9 and the end shearing surface 10 respectively. Specifically, in the embodiment, the design of the arc-shaped shearing surface 11 optimizes the shearing effect, so that the nose hair can be cut more smoothly and painlessly. The main shearing surface 9 is responsible for the main cutting work, and its sharp edge ensures the cutting efficiency, while the end shearing surface 10 serves as an auxiliary to help complete the finishing work of the cutting process. The existence of the arc-shaped shearing surface 11 not only smoothly transitions the angle change between the two main shearing surfaces, reduces the pulling sensation of the nose hair during cutting, but also enhances the durability and cutting precision of the blade.

[0024] Further, a through blade positioning groove 12 is formed on the moving blade holder 2, the moving blade body 7 of each of the two moving blades 4 is connected with the moving blade holder 2 by extending into the blade positioning groove 12 from the two side notches of the blade positioning groove 12, and the elastic member 5 is arranged at the center of the blade positioning groove 12 along the length direction of the blade positioning groove 12, and the two ends of the elastic member 5 abut against the corresponding moving blade body 7. Specifically, in the embodiment, the design of the blade positioning groove 12 helps to ensure the stability and accuracy of the moving blade 4 during installation. Through the guidance of the blade positioning groove 12, the moving blade body 7 of the moving blade 4 can be accurately extended into and connected with the moving blade holder 2, thereby avoiding misplacement or deviation during installation. Meanwhile, the blade positioning groove 12 can also play a certain limiting role on the moving blade 4, preventing it from shaking or deviating during work, and further improving the stability of the shearing space and the shearing efficiency. The elastic member 5 is arranged at the center of the blade positioning groove 12 along the length direction of the blade positioning groove 12, and such a layout can ensure that the elastic force of the elastic member 5 on the two moving blades 4 is uniform and stable. When the moving blade 4 is subjected to resistance during shearing, the elastic member 5 can provide sufficient elastic support, so that the blade edge part 6 of the moving blade 4 always maintains close contact with the inner wall of the static blade 1, thereby ensuring the consistency and reliability of the shearing effect. Specifically, in the embodiment, the two ends of the elastic member 5 abut against the corresponding moving blade body 7, and such a connection mode is not only simple and reliable, but also facilitates disassembly and maintenance.

Specifically, in the embodiment, the width of the gap is 0.1-0.5mm, so as to ensure that the hair can be effectively cut during shearing, and excessive friction force can be avoided to cause too fast blade wear. In addition, a small chamfer is formed at the end of the acute-angle blade edge 8 close to the inner wall of the static blade 1, and the design of the chamfer helps the hair to enter the gap more smoothly, reduces the hair jam phenomenon, and improves the shearing efficiency. Meanwhile, such a design can also reduce the direct contact between the blade and the static blade to a certain extent, thereby prolonging the service life of the blade.

[0026] Further, the bottom end of the moving blade support 2 is provided with a support elastic member 13, one end of the support elastic member 13 abuts against the moving blade support 2, and a pre-pressing force is applied to the moving blade 4 on the moving blade support 2. Specifically, in the embodiment, the support elastic member 13 is a spring, one end of which is fixed on the base of the machine, and the other end abuts against the bottom of the moving blade support 2, and through the elastic force of the spring, a pre-pressing force is generated to the moving blade support 2 in the upward direction. This design can ensure that the moving blade 4 always maintains stable contact with the stationary blade 1 during the shearing process, thereby improving the shearing effect. Meanwhile, the existence of the support elastic member 13 can also effectively buffer the impact force in the shearing process, prolonging the service life of the equipment.
