Description

Technical Field

[0001] The utility model relates to a cutter head, more specifically, to a cutter head structure of a nose hair trimmer. The utility model also relates to a nose hair trimmer using the cutter head. Background Art

[0002] Nose hair trimmer is a beauty tool used to trim nose hair. Some people have nose hair growing outside the nose due to high hormone secretion, living in an environment with poor air quality or smoking, which affects their personal image.

[0003] There are two main types of existing nose hair trimmers. One is an inner and outer cylindrical blade head that cooperates with slow shearing, which is mostly manually operated; the other is an outer blade head that guides the nose hair and cooperates with the internal high-speed rotating blade for shearing.

[0004] Nose hair generally grows toward the center of the nasal cavity, forming an irregular mesh, which is the first line of defense against respiratory diseases. However, in actual observations, it was found that some nose hairs were affected by the hair follicles and their surrounding tissue structures or other nose hairs, and their direction changed during growth, and they would grow along the inner wall of the nasal cavity; in addition, the nose hair located in the depressions on both sides of the nasal vestibule grows more disorderly due to the smaller space. This means that when the above-mentioned existing nose hair trimmers are used, the former has the problem that the nose hair close to the inner wall of the nasal cavity and located in the nasal vestibule is difficult to introduce and the trimming effect is not ideal, and the latter has the same problem and the normal nose hair is cut too thin, which is easy to be inhaled into the nasal cavity, causing irritation and nasal discomfort. Utility Model Content

[0005] The first object of the utility model is to provide a nose hair trimmer head that is easy to introduce nose hair and has a good trimming effect in view of the deficiencies of the above-mentioned prior art.

[0006] The latter object of the utility model is to provide a nose hair trimmer adopting the above-mentioned cutter head.

[0007] The previous technical solution of the utility model is implemented as follows: a nose hair trimmer blade head structure, including an inner blade seat and an outer blade seat which are connected to each other, and a plurality of outer blade heads are evenly distributed along the circumferential edge of the upper end of the outer blade seat; the upper end of the inner blade seat includes a closed guide cone surface and inner blade heads which are evenly distributed on the edge of the guide cone surface along the edge of the inner blade seat and cooperate with the outer blade heads; the nose hair entering the upper end of the inner blade head is guided by the guide cone surface into the shearing portion formed by the inner blade head and the outer blade head.

[0008] In the above-mentioned nose hair trimmer blade head structure, each inner blade head cooperates to form an inner blade assembly, and each outer blade head cooperates to form an outer blade assembly; the inner wall of the outer blade assembly and the outer wall of the inner blade assembly are tightly attached, and the inner wall contour of the outer blade assembly and the outer wall contour of the inner blade assembly are in the shape of a truncated cone that cooperates with each other.

[0009] In the above-mentioned nose hair trimmer blade head structure, the guide surface is in a cone shape with a high middle and low sides, and the inclined surface of the guide surface smoothly extends to the edge of the outer blade holder.

[0010] In the above-mentioned nose hair trimmer blade structure, the angle between the outer shearing edge located at the inner end of the outer blade and the inner shearing edge located at the outer end of the inner blade and matching with each other is 3-25°.

[0011] The latter technical solution of the present utility model is implemented as follows: a nose hair trimmer adopting the above-mentioned cutter head, the trimmer comprises a cutter head, and the cutter head is connected to a driving structure.

[0012] In the above-mentioned nose hair trimmer, the inner blade holder or the outer blade holder is connected to an elastic self-tensioning structure that enables the inner blade head and the outer blade head to fit tightly with each other.

[0013] In the above-mentioned nose hair trimmer, the driving structure is a manual driving structure.

[0014] In the above-mentioned nose hair trimmer, the driving structure is an electric driving structure.

[0015] The above-mentioned nose hair trimmer includes a base body, the electric drive structure is arranged in the base body, and the cutter head is connected to the free end of the base body; an elastic self-tensioning structure is connected between the output end of the electric drive structure and the cutter head.

[0016] In the above-mentioned nose hair trimmer, the elastic self-tensioning structure includes a connecting block connected to the free end of the output shaft of the electric drive structure, and a tensioning spring is sleeved on the output shaft of the electric drive structure at the bottom of the connecting block; a connecting head is provided at the upper end of the connecting block, and a connecting groove matching the connecting head is provided at the bottom of the inner knife seat.

[0017] The inner cutter seat is always in an upward pressing state under the action of the elastic self-tensioning structure, so that the inner cutter head and the outer cutter head are always in close contact.

[0018] After adopting the above structure, the utility model can quickly guide the nose hair entering the upper end of the inner knife seat to the cutting part by setting the guide cone surface. Compared with the existing flat guide surface, it can prevent the nose hair from idling at the upper end of the inner knife seat and failing to enter the cutting part, causing the nose hair to fail to be cut.

[0030] Further preferably, the angle between the outer shearing blade located at the inner end of the outer blade head 3 and the inner shearing blade located at the outer end of the inner blade head 5 and matched is 3-25°. The angle between the inner and outer shearing blades is preferably 15°±5°. Within a reasonable angle range, the inner and outer shearing blades are scissor-shaped and can effectively cut nose hair, avoiding the phenomenon of pulling out nose hair.

[0031] See also Figure 4 and Figure 5 As shown, the utility model is a nose hair trimmer using the above-mentioned cutter head, the trimmer includes a cutter head 6, and the cutter head 6 is connected to a driving structure. The driving structure is a manual driving structure or an electric driving structure. In this embodiment, the driving structure is an electric driving structure. Whether it is a manual driving structure or an electric driving structure, a conventional structure in the art can be adopted. It is not a technical point to be protected by this application and will not be described in detail here.

[0032] At the same time, the inner blade seat 1 or the outer blade seat 2 is connected with an elastic self-tensioning structure that allows the inner blade head 5 and the outer blade head 3 to fit closely with each other. The elastic self-tensioning structure allows the inner and outer blade heads to always be in a tight fit state.

[0033] Preferably, in this embodiment, the trimmer includes a seat body 7, the electric drive structure is arranged in the seat body 7, and the cutter head 6 is connected to the free end of the seat body 7; the elastic self-tensioning structure is connected between the output end of the electric drive structure and the cutter head 6.
