[0066] In addition, the number of the connecting members 250 can be multiple, and the multiple connecting members 250 are arranged circumferentially around the knife cover 40 at intervals, so that the trimmed nose hair can enter the transition cover 20.

[0067] like Figure 1 , Figure 2As shown, the medical nose hair remover includes a shell 10, a transition cover 20, an illuminating lamp 30, a blade cover 40 and a blade head 50; the transition cover 20 is arranged at the top of the shell 10 and is connected to the shell 10, and an opening 210 is arranged at the end of the transition cover 20 away from the shell 10; the illuminating lamp 30 is arranged at the end of the transition cover 20 away from the shell 10 and surrounds the opening 210; the blade cover 40 is rotatably arranged in the opening 210 through a connecting member 250, the blade cover 40 can rotate around the spherical center of the connecting member 250, and the blade cover 40 has a plurality of hair guide grooves 410; the blade head 50 is arranged in the transition cover 20, and one end of the blade head 50 extends into the blade cover 40 and abuts against the blade cover 40; a driving component is arranged in the shell, and the driving component is elastically connected to the blade head 50, drives the blade head 50 to rotate and enables the blade head 50 to move together with the blade cover 40, so as to trim the hair entering the hair guide grooves 410.

[0068] As can be seen from the above, by setting a knife cover 40 that can rotate around the center of the sphere of the connecting member 250, the knife cover 40 can rotate in multiple directions, such as the axial direction and the radial direction, and the cutter head 50 moves together with the knife cover 40, so that the nose hair at various angles in the nasal cavity can be removed and the nose hair can be trimmed without dead angles, solving the problem that the existing nose hair remover has a fixed angle and cannot meet the needs of nose hair trimming at various angles in the nasal cavity; by setting an illumination lamp 30 at the opening 210, the illumination lamp 30 is close to the knife cover 40 and the cutter head 50, and the nasal cavity is illuminated during the nose hair trimming process to ensure a clear field of vision, so that the doctor can check the trimming of the nose hair at any time, thereby solving the problem that the existing nose hair remover lacks an illumination device, resulting in unclear trimming vision in the nasal cavity. In addition, the elastic connection between the drive assembly and the cutter head 50 can not only drive the cutter head to rotate, but also use elasticity to make the cutter head move together with the knife cover while rotating to change the trimming direction, providing a structural basis for achieving nose hair trimming at various angles.

[0069] It should be noted that the transition cover 20 is in a truncated cone shape, and the diameter of one end of the transition cover 20 close to the outer shell 10 is D1, and the diameter of one end of the transition cover 20 away from the outer shell 10 is D2, and D1<D2.

[0070] It should also be noted that the knife cover 40 is a cylindrical structure, and the knife cover 40 can be set to a variety of different diameter specifications as needed to adapt to the nasal cavity sizes of different people; for example, the diameter of the knife cover 40 is 7mm, and the diameter of the knife cover 40 is 5mm, so as to meet the needs of adults and children respectively.

[0071] It should also be noted that the lighting lamp 30 is a ring-shaped structure and is a shadowless LED lamp.

[0072] It should also be noted that the cross section is a plane perpendicular to the axial direction; the rotational connection method of the connecting member 250 and the opening 210 can be the existing technology, for example:

[0073] like Figure 3 As shown, the connecting member 250 is spherical in shape, the diameter of the sphere corresponding to the connecting member 250 is D3, the cross-sectional width of the top end of the connecting member 250 is D4, D4<D3, the cross-sectional width of the bottom end of the connecting member 250 is smaller than D3, and the maximum width of the cross-sectional area of ​​the connecting member 250 is D3;

[0074] A limiting member 220 is arranged in the opening 210, and a limiting groove 230 is arranged in the limiting member 220. The limiting groove 230 is a spherical surface, and the connecting member 250 is located in the limiting groove 230 and is adapted to the shape of the limiting groove 230; the diameter of the sphere corresponding to the limiting groove 230 is D5, and the cross-sectional width of the top of the limiting groove 230 is D6, D6>D4, and the cross-sectional width of the bottom of the limiting groove 230 is less than D5, and the maximum width of the cross section of the limiting groove 230 is D5, and D5 is equal to D3 or D5 is slightly larger than D3, for example, D5 is 1-3mm larger than D3, so that the limiting groove 230 limits the connecting member 250, and the connecting member 250 can rotate 360° in the limiting groove 230;

[0075] In addition, the number of the connecting members 250 can be multiple, and the multiple connecting members 250 are arranged circumferentially around the knife cover 40 at intervals, so that the trimmed nose hair can enter the transition cover 20.

[0076] like Figure 1 , Figure 2 , Figure 4 As shown, in some embodiments, the cutter head 50 includes a cutter column 510, a plurality of blades 520 and a plurality of springs; the cutter column 510 is elastically connected to the driving assembly; the plurality of blades 520 are movably arranged on the cutter column, the plurality of blades 520 are arranged at equal intervals around the circumference of the cutter column, and a groove body 5201 is provided on the side of the cutter blade 520 close to the cutter column 510; the plurality of springs correspond one to one with the plurality of blades 520, the springs are located in the groove bodies 5201 of the corresponding blades 520, one end of the spring is connected to the corresponding blade 520 and the other end is connected to the cutter column 510, so that the blade 520 abuts against the inner wall of the cutter cover 40.

[0077] By setting a spring to make the blade 520 abut against the inner wall of the blade cover 40, it is avoided that the distance between the blade 520 and the inner wall of the blade cover 40 is too large, resulting in the inability to trim the nose hair entering the guide groove 410, thereby improving the trimming efficiency.

[0078] It should be noted that the number of blades 520 is four.

[0079] It should also be noted that a plurality of slide grooves are provided on the outer wall of the blade column 510, and the plurality of slide grooves are arranged at equal intervals around the blade column 510 in the circumferential direction. The plurality of slide grooves correspond one-to-one to the plurality of blades 520, and the blades 520 are movably arranged in the corresponding slide grooves so that the blades 520 can move in the radial direction; in addition, the blades 520 can cooperate with the shape of the slide groove, thereby realizing the movable installation of the blades 520 in the slide groove.

[0080] like Figure 1 , Figure 2 , Figure 5 As shown, in one embodiment, a plurality of whisker guide grooves 410 are arranged circumferentially around the blade cover 40 at intervals; wherein the whisker guide grooves 410 penetrate the blade cover 40 in the radial direction of the blade cover 40, and the whisker guide grooves 410 extend along the axial direction of the blade cover 40.

[0081] By providing a plurality of hair guide grooves 410 , the nose hair can be guided into the blade cover 40 , making it convenient for the blade 520 to trim the nose hair.

[0082] It should be noted that the number of the whisker guide grooves 410 is set according to specific needs. The more the whisker guide grooves 410 are, the larger the contact area with the nasal cavity is. Of course, the number of the whisker guide grooves 410 cannot be too many, as too many will lead to a reduction in the strength of the blade cover 40. For example, the number of the whisker guide grooves 410 is 12.

[0083] In some embodiments, the length of the whisker guide groove 410 is 2 / 3 of the length of the blade cover 40 .

[0084] By setting the length of the hair guide groove 410 to 2 / 3 of the length of the blade cover 40, the length of the hair guide groove 410 is increased, thereby increasing the contact area with the nasal cavity.

[0085] It should be noted that the length of the whisker guide groove 410 is 8 mm.
