[0002] A nasal hair trimmer is a beauty tool for trimming nasal hairs. For some people, due to strong hormone secretion, living in an environment with poor air quality, or smoking, nasal hairs may grow out of the nose, thus affecting personal image.

[0003] Existing nasal hair trimmers mainly have two forms. One is that an inner and outer columnar cutter head is used in cooperation with slow shearing, which is mainly manually operated; the other is that the outer cutter head guides nasal hairs while cooperating with an internally high-speed rotating blade for shearing.

[0004] The growth of nasal hairs generally faces the center position of the nasal cavity, thus forming an irregular network, which is the first line of defense against respiratory diseases. However, in actual observation, it is found that due to the influence of hair follicles and their surrounding tissue structures or other nasal hairs, the growth direction of some nasal hairs changes and they grow along the inner wall of the nasal cavity; in addition, nasal hairs in the concave areas on both sides of the nasal vestibule grow more chaotically due to the small space. This makes the above-mentioned existing nasal hair trimmers have problems in use. For the former, it is difficult to introduce nasal hairs close to the inner wall of the nasal cavity and those in the nasal vestibule, and the trimming effect is not ideal; for the latter, there are the same problems, and normal nasal hairs are cut too finely, which is easy to be inhaled into the nasal cavity, causing irritation and discomfort in the nasal cavity.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] Referring to Figures 1 to 3 as shown, a nasal hair trimmer knife head of the present utility model includes an inner knife holder 1 and an outer knife holder 2 which are sleeved with each other. A plurality of inner knife heads 1a are circumferentially and evenly distributed along the upper end of the inner knife holder 1. A plurality of outer knife heads 2a which are matched with the inner knife heads 1a are circumferentially and evenly distributed along the upper end of the outer knife holder 2. The inner side surface of the free end of the outer knife head 2a is a first guiding inclined surface 3.

[0031] By analyzing the existing cutter head of the nose hair trimmer, it is found that except for the rounded corners on the outer end face of the free end of the outer cutter head, there is no other treatment, which makes the overall free end of the outer cutter head relatively thick. As a result, when in use, the upper end of the outer cutter head needs to be at a position farther away from the inner wall of the nasal cavity to form a notch for the nose hair to enter, resulting in an unsatisfactory shearing effect. Therefore, by setting the first guiding inclined surface, the outer cutter head can form a notch at a position closer to the inner wall of the nasal cavity, facilitating the entry of nose hair and thus improving the shearing effect.

[0032] Preferably, the side surfaces of the outer cutter head 2a on both sides of the first guiding inclined surface 3 are the second guiding inclined surfaces 4, and the first guiding inclined surface 3, the second guiding inclined surfaces 4 and the outer side surface of the outer cutter head 2a cooperate to form a tower shape with a smaller upper part and a larger lower part. Through the setting of the second guiding inclined surface, the opening of the notch is larger and closer to the inner wall of the nasal cavity, and the trimming effect on the nose hair is better.

[0033] In addition, it should be emphasized that the first guiding inclined surface and the second guiding inclined surface can be a plane or an arc surface, and the arc surface can also be concave or convex. In this embodiment, since the overall cutter head is circular, therefore, the first guiding inclined surface is a slightly concave arc surface, and the second guiding inclined surface is a plane. Theoretically, the upper end of the cutter head can also be polished so that its overall shape is close to a frustum shape. Then, both the first guiding inclined surface and the second guiding inclined surface are convex arc surfaces.

[0034] Through repeated experiments, it is found that the distance between adjacent outer cutter heads 2a is 1.1 - 1.8 mm; the distance between the upper ends of adjacent outer cutter heads 2a is 1.4 - 2.5 mm. Within the above parameter range, the nose hair can be quickly introduced into the cutter head and quickly sheared.

[0035] Further preferably, the width W of the upper end of each outer cutter head 2a is 0.1 - 0.5 mm. This can make the free end of the outer cutter head as thin and small as possible on the premise of ensuring safety, so as to be more conducive to the entry of nose hair.

[0036] In this embodiment, a closed guiding surface 1b is provided at the center of the upper end surface of the inner cutter seat 1, and each inner cutter head 1a is arranged at the edge of the guiding surface 1b.

[0037] The nose hair entering the upper end of the inner cutter seat 1 is guided by the guiding surface 1b into the shearing part formed by the inner cutter head 1a and the outer cutter head 2a.

[0038] Further preferably, the guiding surface 1b is in a conical shape with a higher middle part and lower sides, and the inclined surface of the guiding surface smoothly extends to the edge of the outer cutter seat 2. The guiding surface can guide the nose hair into the cutting opening. Through experiments, it is found that when the guiding surface is conical, the nose hair will not rotate idly in the guiding surface, but will quickly enter the nearest cutting opening and will not be randomly guided to other cutting openings or rotate idly because the guiding surface is a plane.

[0039] Further preferably, each inner cutter head 1a cooperates to form an inner cutter assembly, and each outer cutter head 2a cooperates to form an outer cutter assembly; the inner wall of the outer cutter assembly and the outer wall of the inner cutter assembly are in close contact, and the contour of the inner wall of the outer cutter assembly and the contour of the outer wall of the inner cutter assembly are in the shape of a frustum of a cone that cooperate with each other.

[0040] This structure can make the inner and outer cutter assemblies fit tightly together, avoiding gaps between them. At the same time, during operation, the tightly fitting structure can grind the cutting edges of the inner and outer cutter assemblies to keep them sharp, thus ensuring the shearing effect.

[0041] Further preferably, the inner end surface or the upper part of the inner end surface of each inner cutter head 1a is an inclined surface, and the upper end of this inclined surface is located at the lower end of the first guiding inclined surface. The design of the inclined surface can make the upper end of the inner cutter head stick to the outer cutter head as much as possible. This can not only prevent the inner side of the upper end of the inner cutter head from protruding and scratching the nose when rotating, or prevent the user from touching the cutter head with their fingers or touching other body parts with the cutter head during the operation of the trimmer, but also smoothly guide the nasal hair into the shearing part for shearing, avoiding the nasal hair getting stuck at the step between the inner cutter head and the outer cutter. Moreover, this inclined surface preferably follows the first guiding inclined surface, so as to more smoothly guide the nasal hair into the inner cutter.

[0042] Refer to Figure 4 and Figure 5 As shown, a nasal hair trimmer of the present utility model using the above cutter head includes a cutter head 5, and the cutter head 5 is connected with a driving structure. The driving structure is a manual driving structure or an electric driving structure. In this embodiment, the driving structure is an electric driving structure. Whether it is a manual driving structure or an electric driving structure, conventional structures in the art can be adopted, which are not the technical points to be protected in this application and will not be elaborated here.

[0043] Meanwhile, the inner cutter seat 1 or the outer cutter seat 2 is connected with an elastic self-tightening structure for tightly fitting the inner cutter head 1a and the outer cutter head 2a together. Through the elastic self-tightening structure, the inner and outer cutter heads are always in a tightly fitting state.

[0044] Preferably, the trimmer includes a seat body 6, the electric driving structure is arranged inside the seat body 6, and the cutter head 5 is connected to the free end of the seat body 6; an elastic self-tightening structure is connected between the output end of the electric driving structure and the cutter head 5.

[0045] In this embodiment, the elastic self-tightening structure includes a connecting block 7 connected to the free end of the output shaft of the electric driving structure. A tension spring 8 is sleeved on the output shaft of the electric driving structure at the bottom of the connecting block 7; a connecting head 7a is arranged at the upper end of the connecting block 7, and a connecting groove 1c matching with the connecting head 7a is arranged at the bottom of the inner cutter seat 1; the inner cutter seat 1 is always in an upward pressing state under the action of the elastic self-tightening structure, so that the inner cutter head 1a and the outer cutter head 2a are always in close contact.

[0046] During operation, press the switch, and the electric drive structure drives the main and slave rotation of the inner blade through the cooperation of the connector and the connection groove, so that the inner blade assembly and the outer blade assembly cooperate to cut nasal hair.

[0047] In particular, when trimming nasal hair that grows horizontally, clings to the inner wall of the nasal cavity, or is located in the nasal vestibule, due to the setting of the first guiding inclined surface, a notch for guiding nasal hair into the cutting part is formed at a position close to the outer wall of the outer blade head, and the nasal hair in the above special positions can be effectively guided and cut.

[0048] The above embodiments are the preferred embodiments of the present invention, which are only used to conveniently illustrate the present invention and do not impose any form of limitation on the present invention. Any person with ordinary knowledge in the technical field, if within the scope of not departing from the technical features of the present invention, makes local changes or modified equivalent embodiments by using the technical content disclosed in the present invention, and does not depart from the technical feature content of the present invention, still belongs to the scope of the technical features of the present invention.
