[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] The present invention will now be further described with reference to the accompanying drawings.

[0030] This utility model provides the following technical solution:

[0031] As attached Figure 1-10As shown, this utility model discloses an irregularly shaped nose hair trimmer, including a moving blade 1 and a stationary blade 2. A moving blade mounting cavity 3 is formed within the stationary blade 2, and the moving blade 1 is disposed within the moving blade mounting cavity 3. The stationary blade 2 has a stationary blade body portion 4 and a stationary blade cutting portion 5. The inner wall of the stationary blade cutting portion 5 has a first intersecting line 6 and a second intersecting line 7, which intersect and form an included angle α. The moving blade 1 has a moving blade cutting portion 8 corresponding to the stationary blade cutting portion 5, and the moving blade cutting portion 8 has a moving blade cutting end 9 that is clearance-fitted with the included angle α. Specifically, in this design, the first intersecting line 6 and the second intersecting line 7 on the inner wall of the stationary blade cutting portion 5 are respectively located on two cutting surfaces, and these two cutting surfaces intersect to form an included angle α. The setting of the included angle α results in the inner wall of the stationary blade cutting portion 5 having only one bend, thereby simplifying the production process and reducing manufacturing costs. Meanwhile, the clearance fit design between the moving blade shearing end 9 and the included angle α ensures the stability and accuracy of the nose hair cutter during the cutting process, effectively avoiding the risk of accidentally injuring the nasal cavity wall. Furthermore, the included angle α design also makes the fit between the moving blade 1 and the stationary blade 2 tighter, effectively preventing the nose hairs from slipping during cutting and further improving the cutting effect. Users can experience a smoother and more comfortable cutting experience, while also reducing the possibility of needing to repeat operations due to incomplete cutting.

[0032] Furthermore, the stationary blade shearing section 5 has several stationary blade shearing grooves 10, and stationary blade teeth 11 are formed between adjacent stationary blade shearing grooves 10. The outer wall of the stationary blade teeth 11 has a first stationary blade tooth portion 12 and a second stationary blade tooth portion 13 corresponding to the first intersection line 6 and the second intersection line 7, and an arc-shaped transition portion 14 is provided between the first stationary blade tooth portion 12 and the second stationary blade tooth portion 13. Specifically, in this embodiment, the design of the arc-shaped transition portion 14 optimizes the shearing effect of the stationary blade teeth 11, reduces the resistance during the shearing process, and improves the shearing efficiency and comfort of the nose hair trimmer. In addition, the first stationary blade tooth portion 12 and the second stationary blade tooth portion 13 of the stationary blade teeth 11 fit more tightly with the moving blade shearing end 9, ensuring that the nose hair can be effectively clamped and cut during the shearing process, avoiding the pulling and discomfort of the nose hair. At the same time, this design also enhances the structural strength of the stationary blade shearing section 5 and improves the service life of the nose hair trimmer.

[0033] Further, see attached document. Figure 6-7As shown, a stationary blade protrusion 15 is formed between the stationary blade cutting section 5 and the stationary blade body section 4. The inner diameter of the stationary blade protrusion 15 is larger than the inner diameter of the stationary blade body section 4. The moving blade 1 protrudes on both sides near the stationary blade protrusion 15 to form a moving blade fan blade section 16, which is bent to form a curved surface structure. Specifically, in this embodiment, the curved surface structure of the moving blade fan blade section 16 can form a certain gap with the inner wall of the stationary blade protrusion 15. This design not only enhances the stability of the moving blade 1 within the stationary blade 2, but also allows air to pass smoothly through the gap between the moving blade fan blade section 16 and the stationary blade protrusion 15 when using the nose hair trimmer, reducing resistance during use and improving comfort. In addition, the curved surface structure of the moving blade fan blade section 16 also has a certain guiding function, guiding nose hairs into the stationary blade cutting section 5 for better cutting results. Furthermore, the curved structure can absorb fallen hair during the shaving process. Its working principle is as follows: when the moving blade 1 rotates inside the stationary blade 2, the curved structure of the moving blade fan blade 16 is like a small fan blade. The airflow generated will suck the fallen hair into the tiny space between the moving blade 1 and the stationary blade 2, effectively avoiding the inconvenience caused by the hair falling out.

[0034] Further, see attached document. Figure 4-9 As shown, the top of the stationary blade cutting section 5 has several inlet holes 17 that connect to the moving blade mounting cavity 3. Specifically, in this embodiment, the inlet holes 17 also allow the nose hair trimmer to trim eyebrows. After the eyebrows enter the moving blade mounting cavity 3 through the inlet holes 17, they are precisely trimmed by the moving blade 1. This design broadens the application range of the nose hair trimmer, allowing it to not only trim nose hairs but also meet the user's needs for trimming eyebrows. The number and distribution of the inlet holes 17 have been carefully considered to ensure the uniformity and efficiency of the trimming effect. At the same time, the size of the inlet holes 17 has also been optimized to ensure that the eyebrows can enter smoothly while effectively preventing excessive external force from damaging the moving blade 1 and the stationary blade 2, thereby extending the service life of the nose hair trimmer.

[0035] Further, see attached document. Figure 6 As shown, a groove structure 18 is provided on the arc-shaped transition portion 14, and the groove structure 18 extends to the first stationary blade tooth portion 12 and the second stationary blade tooth portion 13 on both sides. Specifically, in this embodiment, by providing the groove structure 18 on the arc-shaped transition portion 14, the nasal hair trimmer can be supported by the groove structure 18 after entering the nostril, thus making the upright nasal hair easier to cut and improving the efficiency and effect of trimming. The design of the groove structure 18 fully considers the physiological structure of the human nostril, ensuring that the nasal hair can enter the groove naturally and comfortably and be supported upright. In addition, the depth and width of the groove structure 18 have also been carefully calculated to effectively support the nasal hair without causing discomfort or damage to the nostril. This design makes the nasal hair trimmer safer and more comfortable to use, and the trimming effect is more ideal.

[0036] Furthermore, the static blade cutting section 5 has a trapezoidal cross-sectional shape, and the inner wall of the static blade body 4 has a third intersecting line 19, with the second intersecting line 7 and the third intersecting line 19 arranged perpendicularly. Specifically, in this embodiment, the trapezoidal cross-sectional design of the static blade cutting section 5 not only enhances its structural strength but also allows the nose hair trimmer to more stably hold the nose hairs during trimming, avoiding incomplete trimming due to slippage. Simultaneously, the perpendicular arrangement of the third intersecting line 19 and the second intersecting line 7 on the inner wall of the static blade body 4 makes the connection between the static blade body 4 and the static blade cutting section 5 more stable, further improving the overall structural strength of the nose hair trimmer. This design not only ensures the stability and durability of the nose hair trimmer during long-term use but also allows users to experience a more stable and reliable cutting experience when trimming nose hairs.

[0037] Furthermore, the moving blade shearing end 9 has an arc-shaped chamfer 20, the diameter of which is 0.05mm-0.3mm. Specifically, in this embodiment, the arc-shaped chamfer 20 allows the moving blade shearing end 9 to contact the stationary blade teeth 11 more smoothly during the shearing process, reducing shearing resistance and improving shearing efficiency. Simultaneously, the arc-shaped chamfer 20 can effectively disperse the stress generated during shearing, extending the service life of the moving blade 1. In addition, the diameter range of the arc-shaped chamfer 20 is set between 0.05mm and 0.3mm, ensuring that the shearing efficiency requirements are met without affecting shearing accuracy due to an excessively large diameter. Furthermore, the diameter range of the arc-shaped chamfer 20, set between 0.05mm and 0.3mm, can partially avoid the stationary blade, minimizing the unshaving end face and preventing fraying caused by unshaving. It also solves the problem of sharp noise.

[0038] Furthermore, while the positions of the first intersecting line 6 and the second intersecting line 7 on the inner wall of the stationary blade cutting section 5 remain unchanged, the cross-sectional shape of the outer wall of the stationary blade cutting section 5 is conical or arc-shaped. Specifically, in this embodiment, the design of the cross-sectional shape of the outer wall of the stationary blade cutting section 5 further optimizes the user experience of the nose hair trimmer. The conical or arc-shaped outer wall cross-sectional shape allows the nose hair trimmer to better adapt to the shape and size of different users' nostrils, improving comfort and fit. This design not only enhances the stability of the nose hair trimmer inside the nostril but also reduces discomfort during use, allowing users to trim nose hairs more easily and pleasantly. At the same time, the conical or arc-shaped outer wall cross-sectional shape also has a certain guiding effect, guiding the nose hair trimmer to enter the nostril more smoothly, further improving ease of use. In other embodiments, the cross-sectional shape of the outer wall of the stationary blade cutting section 5 can also be parabolic, which can better adapt to the contour of the nostril, further improving comfort and stability.

[0039] Reference Appendix Figure 9 As shown, with the intersection of the second intersecting line 7 and the first intersecting line 6 as a reference, the second intersecting line 7 is horizontally arranged. Specifically, in this embodiment, when the second intersecting line 7 is horizontally arranged, the inner wall structure of the stationary blade shearing section 5 is simpler, making it easier to manufacture. At the same time, this design also ensures the stability of the moving blade 1 during the shearing process, ensuring that the nose hairs can be effectively cut.

[0040] Reference Appendix Figure 2 As shown, with the intersection of the second intersecting line 7 and the first intersecting line 6 as a reference, the second intersecting line 7 is inclined towards the lower part of the central axis of the moving blade mounting cavity 3. Specifically, in this embodiment, when the second intersecting line 7 is inclined towards the lower part of the central axis of the moving blade mounting cavity 3, the inner wall of the stationary blade cutting section 5 can form a certain guiding effect during the cutting process, guiding the nasal hairs more smoothly into the cutting area. This design not only improves the cutting efficiency of the nasal hair trimmer but also reduces the pulling sensation of nasal hairs during the cutting process, making the trimming process more comfortable.

[0041] Reference Appendix Figure 10 With the intersection of the second intersecting line 7 and the first intersecting line 6 as a reference, the second intersecting line 7 is inclined towards the upper part of the central axis of the moving blade mounting cavity 3. Specifically, in this embodiment, the inclined setting of the second intersecting line 7 towards the upper part of the central axis of the moving blade mounting cavity 3 enhances the stability and accuracy of the nose hair cutter during the cutting process, and can also effectively reduce the slippage of nose hairs during cutting, thereby improving the cutting effect of the nose hair cutter and the user experience.

Various modifications to these embodiments will be readily apparent to those 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 to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
