Description

Technical Field

[0001] The present application relates to the technical field of daily necessities, and particularly to a nose hair trimmer and a nasal hair clipper. Background Art

[0002] A nasal hair clipper is a trimming tool that emerged with people's increasingly high pursuit of hygiene conditions. It can trim the body hair inside the nostrils to protect the hygiene conditions inside the nasal cavity. Currently, there are various nasal hair clipper products on the market, but their general principles are similar, all achieved by driving the cutter head to rotate with a micro motor.

[0003] Related prior art such as the Chinese patent application "Cutter head structure of a nasal hair clipper", application number: CN202323267762.1, discloses a cutter head structure including a cutter base and a cutter net. A moving cutter is provided on the cutter base, and the moving cutter is arranged inside the cutter net. The top end face of the moving cutter is provided with a cutting edge. The cutter net includes a side wall and a hair inlet wall inclined with respect to the side wall. A plurality of through grooves for nasal hair to enter are provided on the hair inlet wall, and the cutting edge is arranged opposite to the inner wall of the hair inlet wall. A cutter head structure of a nasal hair clipper is provided. Nasal hair enters from the front end face of the cutter net and is cut by the cutting edge at the end of the moving cutter. The tight fit between the moving cutter and the mesh cover can conveniently shave off nasal hair.

[0004] The cutter net adopted by the nasal hair clipper in the prior art has an arc-shaped top surface and an arc transition from the top surface to the wall surface. Its main purpose is to make the overall cutter net round, providing a good user experience and not easily hurting the skin. However, adopting this cutter net structure greatly hinders the introduction of nasal hair into the cutter net, and the nasal hair cannot fully contact the moving cutter to trim the nasal hair. Although the large opening on the top surface of the cutter net can significantly improve the problem of nasal hair introduction, it cannot provide a smooth touch, resulting in a poor user experience. Utility Model Content

[0005] The technical problem to be solved by the present application is to provide a nose hair trimmer and a nasal hair clipper, which further simplifies the cutter net structure and ensures a smooth touch of the nose hair trimmer.

[0006] The technical solution adopted by the present application is as follows: A nose hair trimmer includes a cutter base, a moving cutter group, and a cutter net. The moving cutter group is installed on the cutter base, and the cutter net covers the outside of the moving cutter group. A circle of convex ribs is provided on the outer peripheral surface of the cutter net, and the surface of the convex ribs is smooth. The convex ribs are arranged close to the top surface of the cutter net. The cutter base is connected to a rotating motor, and when the rotating motor works, it drives the moving cutter group to rotate through the cutter net. The top surface and / or side surface of the cutter net is provided with an inlet, and nasal hair enters the cutter net through the inlet and contacts the moving cutter group.

[0007] Compared with the prior art, the advantages of the present application are as follows. When designing the cutter net, a circle of convex ribs is added to its outer peripheral surface, and the convex ribs are arranged close to the top surface of the cutter net. Then when the nose hair trimmer is working and extends or enters the nasal cavity, this circle of convex ribs constitutes the outermost periphery where the nose hair trimmer will contact the user's nose tip and nasal cavity wall. The surface of the convex ribs designed in the present application is smooth, providing a good user experience and being safer. In addition, the outwardly convex convex ribs can form a clearance area for the cutter net part below them, reducing or avoiding contact between other positions of the cutter net and the human body, further improving the user experience.

[0008] In some embodiments of the present application, the cutter net as a whole has a cylindrical structure, the top surface of the cutter net is an open structure and constitutes an inlet; a plurality of openings are provided at the top of the cutter net to form an inlet. Compared with the prior art, the cutter net with a cylindrical open structure adopted in the present application can more smoothly introduce nose hairs, and at the same time provide a smooth touch, with a good user experience.

[0009] In some embodiments of the present application, the cutter net includes a convex rib, a neck, a middle part and a bottom part connected in sequence from top to bottom. The bottom of the cutter net is installed on the net base. The middle part is provided with textures, and the outer diameter of the neck gradually decreases towards the side where the convex rib is located. That is, the structural setting of the neck further cooperates with the convex rib to achieve a clearance structure. With this design, the outer diameter of the convex rib can be made smaller, thus avoiding excessive increase in the outer diameter of the entire cutter net.

[0010] In some embodiments of the present application, the longitudinal section of the convex rib has a semi-circular structure, and the top surface of the convex rib constitutes the top surface of the cutter net. The longitudinal section of the inner wall surface of the cutter net is two parallel line segments. The top surface of the convex rib is the top surface of the cutter net, which means that the user will only contact the convex rib under normal use conditions, and the convex rib has a semi-circular structure, ensuring the user's contact experience. Although the structure of the outer peripheral surface of the cutter net designed in the present application is irregular, the inner wall surface of the cutter net is a regular cylindrical structure, which is used in cooperation with the rotating moving cutter group.

[0011] In some embodiments of the present application, the cutter base includes a mounting post, a disc and a mounting cylinder connected in sequence from top to bottom. The inner hole of the mounting cylinder is a non-circular structure. The inner hole of the mounting seat is connected to the output shaft of the power device, and the moving cutter group is installed at the mounting post. This is the preferred structural solution of the present application.

[0012] In some embodiments of the present application, a long and narrow mounting channel is provided on the mounting post. The mounting channel is arranged along the central axis of the mounting post and penetrates through two opposite side surfaces of the mounting post to form a through surface. The moving cutter group is installed at the mounting channel and passes through the two through surfaces of the mounting channel.

[0013] In some embodiments of the present application, the moving blade group includes two symmetrically arranged blades. There is an included angle between the bent part of the blade edge and the inner wall surface of the knife net, and the included angle is an acute angle. In the present application, the blade rotates relative to the inner wall of the knife net. If the blade is perpendicular to the inner wall surface of the knife net, then this relative movement will continuously wear the blade edge. Therefore, in the present application, the blade edge is designed to be bent. As long as the blade rotates along the direction of the blade edge bending, then this relative movement is equivalent to further grinding the sharpness of the blade edge, which can further extend the service life of the blade.

[0014] In some embodiments of the present application, a number of convex columns are provided on both side wall surfaces of the installation channel. A waist-shaped hole is provided on the blade. The blade is installed in the installation channel, and the convex column passes through the corresponding waist-shaped hole. A linear spring is also provided at the installation channel. The linear spring is in a compressed state, and both ends of the linear spring act on the two blades of the moving blade group respectively. The linear spring applies a force to push the blade to move towards the side of the knife net wall surface.

[0015] In the present application, the linear spring is provided, and in cooperation with the waist-shaped hole on the blade, it is realized that the blade is elastic in the length direction of the linear spring and has a certain displacement deformation, which can effectively prevent the nose hair from getting stuck with the blade after entering. The blade can well adapt to the trimming environment.

[0016] In some embodiments of the present application, a number of baffle plates are provided on the upper part of the disc, and the net seat is erected on the baffle plates. The top surface of the baffle plate is of an arc-shaped structure, and a number of baffle plates are evenly arranged.

[0017] In the present application, by providing a number of baffle plates, the contact surface between the knife seat and the net seat is reduced. Since the knife seat rotates relative to the knife net, reducing the contact surface also realizes the reduction of the frictional force. Further, the top surface of the baffle plate is set to be of an arc-shaped structure, further reducing the contact area and the friction coefficient, thereby reducing the frictional force, and thus realizing the avoidance of wear.

[0018] A nose hair trimmer includes a main body, and the nose hair knife is provided on the main body. The rotating motor is arranged in the main body.

[0019] On the basis of conforming to the common knowledge in the art, the above embodiments can be combined arbitrarily. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will describe the present application in detail with reference to the accompanying drawings.

[0027] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0028] A nose hair trimmer, as shown in Embodiment 1 Figures 1 to 3 : It includes a knife holder 1, a moving knife group 2 and a knife net 3. The moving knife group 2 is installed on the knife holder 1, the knife net 3 covers the outside of the moving knife group 2, and a circle of convex ribs 4 is arranged on the outer peripheral surface of the knife net 3. The surface of the convex ribs 4 is smooth and the convex ribs 4 are arranged close to the top surface of the knife net 3. Then when the nose hair trimmer works and extends or penetrates into the nasal cavity, this circle of convex ribs 4 constitutes the outermost periphery where the nose hair trimmer will contact the user's nose tip and nasal cavity wall. Therefore, in the present application, the surface of the convex ribs 4 is designed to be smooth, resulting in a good user experience and higher safety. The knife holder 1 is connected to a rotating motor. When the rotating motor works, it drives the moving knife group 2 to rotate through the knife net 3. An inlet 6 is arranged on the top surface and / or side surface of the knife net 3, and nose hairs enter the knife net 3 through the inlet 6 and contact the moving knife group 2. The outwardly convex convex ribs 4 can form a clearance area for the part of the knife net 3 below it, reducing or avoiding contact between other positions of the knife net 3 and the human body. Further improving the user experience.

[0029] Embodiment 2, as shown in Figures 1 to 4As shown in the figure, the entire cutter net 3 is in a cylindrical structure. The top surface of the cutter net 3 is an open structure and forms an inlet 6. Multiple openings are provided at the top of the cutter net 3 to form the inlet 6. Compared with the prior art, the cutter net 3 with a cylindrical open structure adopted in this application can introduce nasal hair more smoothly, and at the same time provide a smooth touch, with a good user experience.

[0030] The cutter net 3 includes a convex rib 4, a neck 8, a middle part 9, and a bottom 10 that are connected in sequence from top to bottom. The bottom 10 of the cutter net 3 is installed on the net base 7. The middle part 9 is provided with textures, and the outer diameter of the neck 8 gradually decreases toward the side where the convex rib 4 is located. That is, the structural setting of the neck 8 further cooperates with the convex rib 4 to achieve a clearance structure. With this design, the outer diameter of the convex rib 4 can be made smaller, thereby preventing the overall outer diameter of the cutter net 3 from increasing excessively.

[0031] The longitudinal section of the convex rib 4 is in a semi-circular structure, and the top surface of the convex rib 4 constitutes the top surface of the cutter net 3. The longitudinal section of the inner wall surface of the cutter net 3 is two parallel line segments. The top surface of the convex rib 4 is the top surface of the cutter net 3, that is to say, the user will only contact the convex rib 4 under normal use conditions, and the convex rib 4 is in a semi-circular structure, ensuring the user's contact experience. Although the outer peripheral surface structure of the cutter net 3 is designed to be irregular in this application, the inner wall surface of the cutter net 3 is a regular cylindrical structure and is used in cooperation with the rotating moving cutter group 2.

[0032] Other contents of Embodiment 2 are the same as those of Embodiment 1.

[0033] Embodiment 3, as Figures 2 to 4 shown, the cutter base 1 includes a mounting post 17, a disc 18, and a mounting cylinder 19 that are connected in sequence from top to bottom. The inner hole of the mounting cylinder 19 is a non-circular structure. The inner hole of the mounting seat is connected to the output shaft of the power device, and the moving cutter group 2 is installed at the mounting post 17. This is the preferred structural solution of this application.

[0034] A long and narrow mounting channel is provided on the mounting post 17. The mounting channel is arranged along the central axis of the mounting post 17. The mounting channel penetrates through two opposite side surfaces of the mounting post 17 to form a through surface. The moving cutter group 2 is installed at the mounting channel, and the moving cutter group 2 passes out through the two through surfaces of the mounting channel.

[0035] The described moving knife group 2 includes two symmetrically arranged blades 11. There is an angle between the bent part at the cutting edge 12 of the blade 11 and the inner wall surface of the knife net 3, and the angle is an acute angle. In this application, the blade 11 rotates relative to the inner wall of the knife net 3. If the blade 11 is perpendicular to the inner wall surface of the knife net 3, then this relative movement will continuously wear the cutting edge 12 of the blade 11. Therefore, in this application, the cutting edge 12 of the blade 11 is designed to be bent. As long as the blade 11 rotates along the direction of the bend of the cutting edge 12, then this relative movement is equivalent to further grinding the sharpness of the cutting edge 12, which can further extend the service life of the blade 11.

[0036] A number of convex columns 13 are provided on both side wall surfaces of the described installation channel. A waist-shaped hole 14 is provided on the blade 11. The blade 11 is installed in the installation channel, and the convex column 13 passes through the corresponding waist-shaped hole 14. A linear spring 15 is also provided at the installation channel. The linear spring 15 is in a compressed state. The two ends of the linear spring 15 act on the two blades 11 of the moving knife group 2 respectively, and the linear spring 15 applies a force to push the blade 11 to move towards the side of the wall surface of the knife net 3.

[0037] In this application, the linear spring 15 is provided, cooperating with the waist-shaped hole 14 on the blade 11, to make the blade 11 elastic in the length direction of the linear spring 15 and have a certain displacement deformation, which can effectively prevent the nose hair from getting stuck with the blade 11 after entering. The blade 11 can well adapt to the trimming environment.

[0038] A number of baffles 16 are provided on the upper part of the disc 18. The net seat 7 is erected on the baffles 16. The top surface of the baffle 16 is in an arc structure, and a number of baffles 16 are evenly arranged.

[0039] In this application, by providing a number of baffles 16, the contact surface between the knife seat 1 and the net seat 7 is reduced. Since the knife seat 1 rotates relative to the knife net 3, reducing the contact surface also reduces the frictional force. Further, the top surface of the baffle 16 is in an arc structure, which further reduces the contact area and the friction coefficient, thereby reducing the frictional force and achieving wear avoidance.

[0040] The other contents of Embodiment 3 are the same as those of Embodiment 1 or Embodiment 2.

[0041] A nose hair trimmer, Embodiment 4, includes a main body, and the nose hair knife as described in any one of Embodiments 1 to 3 is provided on the main body. The rotating motor is arranged inside the main body.

[0042] The above has introduced the present application in detail. Specific examples are used herein to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only for helping to understand the present application and its core idea. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present application, several improvements and modifications can still be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
