Detailed Implementation Methods
[0029] The present invention will be further described below with reference to the accompanying drawings:
[0030] like Figures 1 to 7 The illustrated nose hair trimmer cutting assembly includes a blade net 1 and a moving blade assembly. The blade net 1 has a cutting cavity 13 for the moving blade assembly to move within it. The blade net 1 includes a blade net sidewall 11, on which cutting teeth are spaced apart in a circumferential direction. Hair inlet pores 14 are formed between the cutting teeth. The upper ends of the plurality of cutting teeth have curved portions 1211 that bend toward the center of the cutting cavity 13, and extension portions 1212 that extend downward from the curved portions 1211. The plurality of extension portions 1212 are connected by an intermediate connecting portion 15. Together, the extensions 1212 form a recessed groove 150 from top to bottom. Adjacent extensions 1212 are spaced apart to form a portion of an inlet 14, connecting the inlet 14 to the groove 150. The moving blade assembly includes a moving blade support 3 and a blade 4 mounted on the moving blade support 3. The blade 4 has a side cutting edge 41 that engages with cutting teeth to cut hair. The side cutting edge 41 is located between the blade sidewall 11 and the intermediate connecting portion 15, and its upper end is higher than the intermediate connecting portion 15. Figure 4 As shown, when trimming nose hairs, the blade 1 is inserted into the nostril. After the horizontally growing nose hairs 10 enter the pore 14, they can fall downwards through the concave groove 150. The lowest position where they fall is on the middle connecting part 15, where they are blocked. The upper end of the side cutting blade 41 is higher than the middle connecting part 15, which makes it easier for the nose hairs 10 to fall into the cutting range of the side cutting blade 41, so that the nose hairs can be cut off and the efficiency of trimming nose hairs can be improved.
[0031] Furthermore, the pore 14 includes a narrow opening 141 at the lower part and a wide opening 142 at the upper part that is wider than the narrow opening 141. The wide opening 142 and the narrow opening 141 are connected vertically. The position of the narrow opening 141 is used to cut nasal hairs corresponding to the side cutting blade 41 that rotates inward. By providing the narrow opening 141 to cooperate with the side cutting blade 41, the safety of cutting is improved. When the blade net 1 is in the nostril, including but not limited to rotating, swinging and / or moving inward and outward, the wide opening 142 facilitates the entry of nasal hairs. After the nasal hairs enter the wide opening 142, they can easily enter the narrow opening 141 from the wide opening 142, thereby increasing the probability of the nasal hairs entering the cutting position for cutting.
[0032] Preferably, such as Figures 1-6 As shown, the cutting teeth include multiple long blades 121 and multiple short blades 122. Several short blades 122 are arranged between adjacent long blades 121. The heads of the short blades 122 are free ends. The hair inlet 14 is formed between adjacent long blades 121. The short blades 122 form narrow openings 141 on their left and right sides with adjacent long or short blades 121 or 122. Two long blades 121 form a wide opening 142 at the top of the short blades 122. The curved portion 1211 and the extension portion 1212 are provided on the long blades 121. Through the combination of long and short blades, while ensuring a suitable width for the narrow opening 141, the wide opening 142 can have a larger width. Moreover, one wide opening 142 corresponds to two or more narrow openings 141 simultaneously, improving the efficiency of nose hairs entering the narrow opening 141 from the wide opening 142 and increasing the efficiency of hair trimming.
[0033] Of course, it can also be like Figure 7 As shown, the cutting tooth is composed of long cutting teeth 121, which includes a thin upper section and a thick lower section. Two long cutting teeth 121 form a wide opening 142 between the thin sections and a narrow hole 141 between the thick sections. It has a small number of teeth, a simple structure, and is easy to manufacture.
[0034] Preferably, such as Figure 3 As shown, the upper end of the narrow hole 141 is higher than the upper end of the side cutting blade 41, protecting the side cutting blade 41 on the inside to improve safety. The bottom 140 of the narrow hole 141 is lower than the top of the intermediate connecting part 15. The side cutting blade 41 is attached to the inner wall of the blade net 1 and cooperates with the cutting teeth during rotation to cut the hair entering the narrow hole 141. Figure 4 As shown, when the nose hair 10 is blocked between the bottom 140 and the middle connecting part 15 of the narrow hole 141, the nose hair 10 is obliquely downward from the middle connecting part 15 to the bottom 140 of the narrow hole 141, which makes it easier for the nose hair 10 to be cut by the side cutting blade 41.
[0035] Preferably, such as Figures 3-5In the shown embodiment, the intermediate connecting part 15 and the movable cutter assembly are provided with a center positioning structure for center positioning when the movable cutter assembly rotates, which is beneficial to improve the stability of the movable cutter assembly when rotating, so as to reduce noise, noise, jamming and other adverse effects, and improve the cutting sharpness. Preferably, the center positioning structure comprises a positioning column 10 arranged at the bottom of the intermediate connecting part 15, and a center positioning hole 30 arranged on the movable cutter support 3. Of course, the center positioning hole 30 can also be arranged on the intermediate connecting part 15, and the positioning column 10 matched with the center positioning hole 30 can be arranged on the movable cutter support 3, which is omitted here.
[0036] Preferably, as shown, Figure 2 the rear side surface 120 of the cutting tooth is arranged eccentrically relative to the center of the cutter net 1 and forms an acute angle α with the inner wall of the cutter net side wall 11 in the direction V of the rotation of the blade 4, which improves the cutting sharpness.
[0037] Preferably, the angle β of the cutting edge of the side cutting edge 41 is less than 90°, which improves the cutting sharpness.
[0038] As shown in the shown embodiment, two opposite blades 4 are arranged on the movable cutter support 3, and a spring 5 is arranged between the two blades 4 to laterally press the blades 4 and make the side cutting edge 41 adhere to the inner wall of the cutter net side wall 11, which is beneficial to improve the cutting sharpness. Figures 3-5
[0039] As shown in the shown embodiment, two opposite blades 4 are arranged on the movable cutter support 3, and a spring 5 is arranged between the two blades 4 to laterally press the blades 4 and make the side cutting edge 41 adhere to the inner wall of the cutter net side wall 11, which is beneficial to improve the cutting sharpness.
