[0033] A nose hair trimmer with guiding comb teeth according to embodiments of the present application is described with reference to Figs. 1-10.
[0034] As shown in Figs. 1-10, the nose hair trimmer with guiding comb teeth according to embodiments of the present application comprises a housing 100; a fixed knife 200 coaxially arranged on the housing 100, the fixed knife 200 being fixedly connected with the housing 100, the fixed knife 200 having a collecting cavity 210, a plurality of guiding comb teeth 220 and a plurality of guide grooves 230 being arranged on the fixed knife 200, the plurality of guiding comb teeth 220 being in the shape of a turbine, the plurality of guide grooves 230 all being in communication with the collecting cavity 210, the plurality of guiding comb teeth 220 and the plurality of guide grooves 230 being spaced and arrayed along the circumferential direction of the fixed knife 200, each guide groove 230 extending from the end face of the fixed knife 200 to the side wall, the guide groove 230 extending along the chord direction on the end face of the fixed knife 200, the groove wall of the guide groove 230 having an included angle with the axial direction of the fixed knife 200; a moving knife mechanism 300 coaxially arranged with the fixed knife 200, the moving knife mechanism 300 being rotatably connected with the fixed knife 200, the moving knife mechanism 300 comprising two moving knives 310 symmetrically arranged in the collecting cavity 210, the two moving knives 310 all being rotatably connected with the plurality of guiding comb teeth 220, the two moving knives 310 being rotated around the axial direction of the fixed knife 200 so that the two moving knives 310 alternately abut against the plurality of guiding comb teeth 220 to form cross-cut shearing to trim the hair located in the guide grooves 230; a driving mechanism 400 arranged on the housing 100, the driving mechanism 400 being connected with the moving knife mechanism 300, the driving mechanism 400 being used to drive the moving knife mechanism 300 to rotate in the housing 100.
[0035] As shown in FIG. 1 and FIG. 2, the housing 100 is taken as the axis in the up-down direction, the fixed knife 200 is fixedly arranged on the housing 100, the inside of the fixed knife 200 is enclosed to form a collection cavity 210, specifically, the upper end surface of the fixed knife 200 is horizontally arranged, the edges of the fixed knife 200 are arranged with a plurality of guide combs 220 and a plurality of guide grooves 230 in the circumferential direction, and the plurality of guide combs 220 and the plurality of guide grooves 230 are arranged in a circumferential array. Wherein, each guide groove 230 extends downward from the upper end surface of the fixed knife 200 to the side wall of the fixed knife 200, forming an L-shaped groove body, the groove segment located at the end surface part of the fixed knife 200 extends in the chord direction, and the groove wall of the guide groove 230 has an angle α with the axis direction of the fixed knife 200, α satisfies: α≠0°, that is, the guide groove 230 is an inclined groove arranged in an inclined manner. Two moving knives 310 are arranged in the collection cavity 210, the two moving knives 310 are symmetric about the axis center of the housing 100, the two moving knives 310 are both rotationally connected with the housing 100, that is, the two moving knives 310 are both rotationally connected with the fixed knife 200, and the end part of each moving knife 310 abuts against the inner wall of the fixed knife 200. Therefore, when rotating the moving knife 310 around the axis direction of the fixed knife 200, the two moving knives 310 alternately abut against the plurality of guide combs 220, parallel movement is formed between the two, and cross shearing is formed, the guide groove 230 accurately guides the nasal hair or other hair to the optimal trimming position, thereby ensuring the accuracy of hair trimming and improving the quality of hair trimming.
[0036] Specifically, in use, the moving knife 310 rotates along the extension direction of the plurality of guide grooves 230 on the upper end surface of the fixed knife 200, in the specific embodiment, the extension direction of the guide groove 230 is offset to the right of the diameter of the end surface of the fixed knife 200, that is, the opening ends of the plurality of guide grooves 230 are arranged in a radial clockwise manner, so the moving knife 310 rotates clockwise.
[0037] Specifically, the width of the guide groove 230 gradually decreases along the depth direction of the guide groove 230. As shown in FIG. 4, the guide grooves 230 are arranged in a radial manner on the circumference of the fixed knife 200, and the guide grooves 230 have an angle with the axial direction of the fixed knife 200, the rotation directions of the plurality of guide grooves 230 are the same, and the horizontal width of each guide groove 230 gradually increases along the extension direction of the guide groove 230 towards the opening, so as to expand the hair accommodation area and improve the efficiency of hair trimming.
[0038] Specifically, the fixed knife 200 is detachably connected with the housing 100 through a threaded structure, so when the trimming is completed, the hair in the collection cavity 210 can be removed by rotating and detaching the fixed knife 200.
[0039] In some embodiments of the present application, the first cutting edges 221 are arranged on each of the guide combs 220, and are located at one end of the side wall of the fixed knife 200 close to the collection cavity 210. The second cutting edges 311 are arranged on at least one of the moving knives 310 close to one end of the side wall of the fixed knife 200, and rotate around the axis of the fixed knife 200. The second cutting edges 311 and the first cutting edges 221 alternately abut to form cross shearing.
[0040] In some embodiments of the present application, the third cutting edges 222 are arranged on each of the guide combs 220, and are located at one end of the end surface of the fixed knife 200 close to the collection cavity 210. The fourth cutting edges 312 are arranged on at least one of the moving knives 310 close to one end of the end surface of the fixed knife 200, and rotate around the axis of the fixed knife 200. The third cutting edges 222 and the fourth cutting edges 312 alternately abut to form cross shearing.
[0041] As shown in FIG. 3, the two moving knives 310 are centrally symmetrical. Taking the right moving knife 310 as an example, the right end of the moving knife 310 is provided with the second cutting edge 311, and the upper end of the moving knife 310 is provided with the fourth cutting edge 312. As shown in FIGS. 4 and 5, the first cutting edges 221 and the third cutting edges 222 are arranged on the guide combs 220. The first cutting edges 221 are located on the inner side wall of the fixed knife 200, and the third cutting edges 222 are located on the inner wall of the end surface of the fixed knife 200. It should be noted that the inner side wall of the fixed knife 200 and the inner wall of the end surface of the fixed knife 200 are the cavity walls of the collection cavity 210. Specifically, the first cutting edges 221 correspond to all the third cutting edges 222, and the first cutting edges 221 can alternately abut to all the third cutting edges 222. Similarly, the second cutting edges 311 correspond to all the fourth cutting edges 312, and the second cutting edges 311 can alternately abut to all the fourth cutting edges 312. Thus, when rotating along the axis of the fixed knife 200 and along the extension direction of the plurality of guide grooves 230, the second cutting edges 311 on the two moving knives 310 move in parallel with and alternately abut to all the first cutting edges 221, and the fourth cutting edges 312 on the two moving knives 310 move in parallel with and alternately abut to all the third cutting edges 222. The first cutting edges 221 and the third cutting edges 222, and the second cutting edges 311 and the fourth cutting edges 312 form L-shaped trimming regions, which can simultaneously trim the hair near the side surface of the fixed knife 200 and the end surface of the fixed knife 200, so as to expand the trimming range and improve the efficiency of hair trimming.
[0042] Of course, the moving knives 310 on the left and right sides can be provided with the second cutting edges 311 alternatively, and the other with the fourth cutting edges 312. When rotating along the axis of the fixed knife 200 and in the extension direction of the plurality of guide grooves 230, the second cutting edges 311 on one of the moving knives 310 move in parallel with all the first cutting edges 221 and alternately abut, and the fourth cutting edges 312 on the other moving knife 310 move in parallel with all the third cutting edges 222 and alternately abut. The first cutting edges 221 and the third cutting edges 222, and the second cutting edges 311 and the fourth cutting edges 312 can also form L-shaped trimming areas to trim the hair near the side surface of the fixed knife 200 and the end surface of the fixed knife 200.
[0043] In some embodiments of the present application, one end of the second cutting edge 311 is connected to the moving knife 310 through the first folding part 3111, and the first folding part 3111 protrudes away from the rotating direction of the moving knife 310. One end of the fourth cutting edge 312 is connected to the moving knife 310 through the second folding part 3121, and the second folding part 3121 protrudes away from the rotating direction of the moving knife 310.
[0044] As shown in FIG. 6, the cross sections of the second cutting edge 311 and the fourth cutting edge 312 are both acute angles. The second cutting edge 311 is inclined forward to the left through the first folding part 3111, and the fourth cutting edge 312 is inclined forward to the left through the second folding part 3121. The inclination directions of the second cutting edge 311 and the fourth cutting edge 312 are consistent with the rotating direction of the moving knife 310. When the second cutting edge 311 and the fourth cutting edge 312 are inclined forward to the cutting direction, they will contact and cut the hair at a smaller angle, which helps to guide the knife edge to cut the material accurately and smoothly, reduces the resistance and extrusion of the material, so that the knife edge can penetrate the hair more easily, reduces the pulling of the hair, and reduces the damage to the nasal cavity caused by hair trimming.
[0045] In some embodiments of the present application, the moving knife 310 is further provided with two positioning members 313. The two positioning members 313 are located at the same end of the moving knife 310 as the fourth cutting edge 312. The two positioning members 313 are flush with the fourth cutting edge 312 away from the end of the moving knife 310. The two positioning members 313 abut the end surface of the fixed knife 200. The positioning member 313 is used to limit the position of the fourth cutting edge 312.
[0046] As shown in FIG. 6, the movable cutter 310 is in a U-shaped form, specifically, the movable cutter 310 has a first panel 314, a second panel 315, and a bent panel 316, wherein the first panel 314 is located at the front side of the second panel 315, the first panel 314 and the second panel 315 are connected through the bent panel 316 at the left end, the second blade edge 311 is arranged at the right end of the second panel 315, and the fourth blade edge 312 is arranged at the upper end of the second panel 315. The upper end of the first panel 314 is provided with a positioning piece 313, the upper end of the second panel 315 is provided with a positioning piece 313, the two positioning pieces 313 are flush with the fourth blade edge 312, and further, the two positioning pieces 313 correspond to each other. Thus, the two positioning pieces 313 and the fourth blade edge 312 form a triangular positioning and abut the inner wall of the end surface of the fixed cutter 200, so as to ensure that the movable cutter 310 can stably abut against the third blade edge 222 during rotation, and further, the movable cutter 310 and the fixed cutter 200 cooperatively form a cross shearing.
[0047] In some embodiments of the present application, the guide comb 220 is provided with a first bent portion 240 and a second bent portion 250, the first bent portion 240 protrudes towards the side of the fixed cutter 200 away from the movable cutter 310, and the second bent portion 250 is arranged at the lower end of the first bent portion 240 and smoothly transitions with the first bent portion 240, the second bent portion 250 protrudes towards the side of the fixed cutter 200 adjacent to the movable cutter 310.
