[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only some of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the utility model.

[0021] ​The present invention will now be further described with reference to the accompanying drawings.

[0022] This utility model provides the following technical solution:

[0023] As attached Figures 1-5 As shown, this utility model discloses a static blade structure for a nose hair trimmer, including a static blade body 1. The static blade body 1 has a plurality of static blade teeth 2 arranged in a circular array along its axis. A hair-guiding groove is formed between adjacent static blade teeth 2. The key feature is that at least a partial inclined surface 3 is provided on at least one of the two sidewalls of each static blade tooth 2, increasing the width of the opening of the hair-guiding groove between adjacent static blade teeth 2. Specifically, in this design, by providing an inclined surface 3 on at least a partial portion of at least one of the two sidewalls of each static blade tooth 2, nose hairs, after entering the hair-guiding groove, are guided by the inclined surface 3, allowing for smoother cutting, reduced cutting resistance, and improved cutting efficiency. Simultaneously, the inclined surface 3 effectively prevents nose hairs from getting stuck or tangled during cutting, ensuring the smoothness and reliability of the nose hair trimmer. Furthermore, the inclined surface 3 also increases the sharpness of the static blade teeth 2 to a certain extent, allowing for faster cutting of nose hairs and further enhancing the user experience. Furthermore, the inclined surface 3 is set so that the opening of the hair guide groove between adjacent static blade teeth 2 facing outward is at least locally wider. This design provides more space for the nose hair to move after it enters the hair guide groove, reducing the risk of poor cutting or skin damage caused by the narrow space.

[0024] Further, see attached document. Figures 1-2 As shown, the stationary blade 2 has a blade head 4, a blade body 5, and a corner portion 6 disposed between the blade head 4 and the blade body 5. The inclined surface 3 is disposed at least at one of the blade head 4, the blade body 5, or the corner portion 6. Specifically, in this embodiment, the inclined surface 3 is disposed at at least one position on the blade head 4, the blade body 5, or the corner portion 6, which can more flexibly adapt to the needs of cutting nose hairs of different lengths and directions. When the inclined surface 3 is disposed on the blade head 4, it can more directly guide and cut the nose hairs entering the guide groove, improving the cutting accuracy; when the inclined surface 3 is disposed on the blade body 5, it can increase the stability during the cutting process, ensuring that the nose hairs are cut smoothly; and when the inclined surface 3 is disposed on the corner portion 6, it can better adapt to the bending changes of the nose hairs during the cutting process, reducing the jamming phenomenon during cutting. This design not only improves the cutting efficiency of the nose hair cutter, but also further enhances its user comfort and durability.

[0025] Further, see attached document. Figures 3-5As shown, the inclined surface 3 is arranged on the corner portion 6, and the two ends of the inclined surface 3 extend towards the cutter head portion 4 and the cutter body portion 5 respectively, and there is a gap between the two ends of the inclined surface 3 and the end of the cutter head portion 4 and the end of the cutter body portion 5 respectively. Specifically, in this embodiment, the design of the inclined surface 3 arranged on the corner portion 6 not only optimizes the guiding path of the nasal hair, but also enhances the structural strength of the static cutter 2. The gap between the two ends of the inclined surface 3 and the end of the cutter head portion 4 and the end of the cutter body portion 5 ensures that the nasal hair can smoothly enter and slide along the inclined surface 3 during cutting without being hindered too much. This design further reduces friction and resistance during cutting, making the nasal hair cutter more efficient and smooth during use. At the same time, since the inclined surface 3 is arranged on the corner portion 6, the static cutter 2 can be more evenly stressed during cutting of the nasal hair, prolonging the service life of the static cutter 2 and improving the overall durability of the nasal hair cutter.

[0026] Further, the inclined surface 3 is arranged on the corner portion 6, and one end of the inclined surface 3 extends towards the cutter head portion 4, and there is a gap between the inclined surface 3 and the end of the cutter head portion 4. Specifically, in this embodiment, the gap is arranged to ensure that the nasal hair can smoothly enter and slide along the inclined surface 3 to the cutter head portion 4 for cutting without being unnecessarily hindered by being too close to the end of the cutter head portion 4. This design detail further optimizes the smoothness of nasal hair cutting, while also helping to reduce noise and vibration that may occur during cutting, improving the overall comfort of use. In addition, the gap between the inclined surface 3 and the end of the cutter head portion 4 also facilitates subsequent cleaning and maintenance, ensuring that the nasal hair cutter can maintain good working condition for a long time.

[0027] Further, the inclined surface 3 is arranged on the two outer edges of the static cutter 2, and the inclined surface 3 extends from the two outer edges of the end of the cutter body portion 5 to the two outer edges of the cutter head portion 4, and passes through the two outer edges of the corner portion 6. Specifically, in this embodiment, the inclined surface 3 is arranged on the two outer edges of the static cutter 2, which can effectively reduce the resistance during cutting of the nasal hair, making the cutting process more smooth. At the same time, the extension of the inclined surface 3 also ensures the stability of the cutter during cutting, avoiding shaking due to uneven stress, further improving cutting efficiency and safety. In addition, the inclined surface 3 passes through the two outer edges of the corner portion 6, so that the corner portion 6 also participates in the cutting process, increasing the cutting area and thus improving the overall performance of the nasal hair trimmer.

[0028] Further, tooth grooves 7 are formed between adjacent static blade teeth 2, the outer side of the groove walls between the two static blade teeth 2 is inclined towards the upper part of the axis of the static blade body 1, and the opposite outer edges of the adjacent static blade teeth 2 and the groove walls between the two static blade teeth 2 form a bell mouth structure. Specifically, in this embodiment, the tooth grooves 7 formed between adjacent static blade teeth 2 have groove walls whose outer side is inclined towards the upper part of the axis of the static blade body, which optimizes the hair guiding path. When the hair enters these tooth grooves, it will be smoothly guided to the bell mouth structure along the inclined groove walls. The bell mouth structure is formed by the opposite outer edges of the adjacent static blade teeth and the groove walls, which further enhances the hair guiding effect. When the hair passes through the bell mouth, it is more effectively controlled and guided due to the gradual narrowing of the structure. This not only improves the cutting efficiency, but also reduces the possibility of hair entanglement and blockage.

[0029] Further, the inclined surface 3 has a spacing with the end of the blade tooth head 4. Specifically, in this embodiment, the size of the spacing can be adjusted according to actual needs to ensure that the cutting effect is optimal. By setting this spacing, excessive friction between the inclined surface 3 and the end of the blade tooth head 4 during cutting can be effectively avoided, wear is reduced, and service life is improved. At the same time, the setting of the spacing also helps to improve the flexibility of cutting, making the cutting process smoother.

[0030] Further, the inclination angle of the inclined surface 3 is 45-50°. Specifically, in this embodiment, when the inclination angle is 45-50°, the hair can be ensured to receive appropriate guiding force when it contacts the inclined surface, neither causing hair jam due to too large an angle, nor weakening the guiding effect due to too small an angle. This design enables the hair to more smoothly slide into the tooth groove along the inclined surface, further improving the cutting efficiency and reducing machine failures caused by hair entanglement or blockage.

[0031] The above description of the disclosed embodiments enables a person skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application should not be limited to the embodiments shown herein, but should be consistent with the widest scope consistent with the principles and novel features disclosed herein.
