Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nose hair cutter for cutting nose hair.

[0002]

2. Description of the Related Art The basic structure of a conventional nose hair cutter 50 will be described with reference to FIGS. The column-shaped main body case 52 has a built-in electric motor 64 and the like, and a switch button 54 is arranged on a surface thereof. The head portion 56 is detachably provided on one end side of the main body case 52, and has an outer shape formed in a truncated cone shape as an example. The fixed blade 58 has a cylindrical outer shape, and protrudes from the tip of the head portion 56. At its tip end, hair introduction grooves 60 are provided side by side at equal angular intervals in the circumferential direction substantially along the axis L direction.

The base 62 is formed in a columnar shape, and is rotatably disposed at a mounting position of the head portion 56 of the main body case 52. As an example, in this example, the base 62 is integrally rotatably attached to a rotating shaft 64 a of the electric motor 64 built in the main body case 52, which protrudes from the surface of the main body case 52. The detailed structure of the base 62 is such that a concave portion 68 into which a joint 66 having a non-circular cross section attached to a rotating shaft 64a of an electric motor 64 is formed on a lower surface, and a plate-like stopper 70 is provided on an upper surface, and an axis L Are projected at equal angular intervals around the center. In this example, two stoppers 70 are provided as an example. One notch 70a along the axis L is formed on the upper end side of each stopper 70.

The movable blade 72 is provided on the surface (upper surface) of the base 62.
And the same number as the stoppers 70 are provided at equal angular intervals about the axis L. The movable blade 72 has a blade portion 72 a that is bent in a substantially rectangular shape so as to slide on the inner peripheral surface of the fixed blade 58.
Are constituted by a plurality of plate-like spring members 72b formed at the tips. The movable blade 72 is arranged so that the plate-shaped spring member 72b is arranged along the inner surface of each stopper 70, and the blade portion 72a that slides on the inner peripheral surface of the fixed blade 58 fits into the notch 70a of the stopper 70. Then, the outer surface of the blade portion 72a is
It protrudes from the outer surface of the stopper 70. Further, the plate-like spring member 72b is inclined from the surface of the base 62 in advance toward the inner peripheral surface of the fixed blade 58 so that the blade portion 72a is always biased toward the inner peripheral surface of the fixed blade 58. Although it extends, the opening of the blade portion 72a in the direction toward the inner peripheral surface of the fixed blade 58 is regulated to a predetermined amount by contacting the inner surface of the stopper 70. Thus, when the movable blade 72 is inserted into or removed from the head portion 56 to which the fixed blade 58 is attached, the movable blade 72 is hardly hooked on the inner surface of the fixed blade 58 to be easily inserted or removed. Deformation is prevented.

[0005]

However, the movement of the movable blade 72 toward the fixed blade 58 as in the conventional example is not limited to the base 6.
2, the shaved nose hairs enter between the stopper 70 and the plate-like spring member 72b of the movable blade 72, and the plate-like spring member 72b
At the same time, the blade portion 72a moves in the direction of the axis L, and as a result, the contact pressure of the blade portion 72a of the movable blade 72 with the inner surface of the fixed blade 58 is reduced. There is a problem to do. Also, the stopper 70
Since the nose hairs that have entered between the movable blade 72 and the plate-like spring member 72b are constantly pressed against the stopper 70 by the movable blade 72, there is also a problem that cleaning is difficult. Accordingly, the present invention has been made to solve the above-described problems, and an object of the present invention is to provide a nose hair cutter in which shaving taste is hardly reduced by shaved nose hair.

[0006]

The present invention has the following arrangement to achieve the above object. In other words, the nose hair cutter according to the present invention includes a cylindrical fixed blade that protrudes from a head portion that is detachably attached to a main body case and has hair introduction grooves extending along an axial direction arranged in a circumferential direction, and the head of the main body case. A nose hair cutter having a movable blade that is attached to a base rotatably disposed at a mounting portion of the portion and that rotates while sliding with the inner surface of the fixed blade inside the fixed blade mounted on the head portion; The movable blade includes a plurality of plate-shaped spring members extending from a surface of the base and having a blade portion formed at a tip thereof which slides on an inner peripheral surface of the fixed blade. In the invention, an opening stop ring for regulating the opening of the blade portion in the direction toward the inner peripheral surface of the fixed blade is collectively fitted to the outside.

[0007] According to this, since there is no plate-like stopper extending from the base as in the prior art, nose hairs do not accumulate between the stopper and the movable blade, and a reduction in shaving quality can be suppressed. In particular, since the stop ring is merely fitted to a plurality of plate-shaped spring members at the same time, it is relatively movable with respect to the movable blade, so that the inner peripheral surface of the stop ring and the outer periphery of the movable blade are provided. The nose hair between the surface and the nose easily falls on the base.

Further, if a restricting piece for restricting the movement of the opening retaining ring toward the base is protruded from the plate-like spring member, it opens when the movable blade is mounted in the fixed blade. It is possible to prevent the stop ring from moving toward the base of the plate-shaped spring member.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a nose hair cutter according to the present invention will be described below with reference to FIG. In addition,
Since the nose hair cutter 50 described in the conventional example has basically the same configuration except for the configuration of the movable blade and the stopper, the description will be made with reference to FIG. 2A showing the outer shape of the nose hair cutter. The same components as those in the related art are denoted by the same reference numerals, and detailed description is omitted. Nose hair cutter 10
The basic configuration of the main body 52 includes a main body case 52 in which a motor 64 and the like are incorporated, a head portion 56, a fixed blade 58 provided in the head portion 56, a base 62, a movable blade 12, and a movable blade 12.
And a stopper. The feature of this embodiment lies in the configuration of the movable blade 12 and its stopper as described above, and the other configuration is the same as the conventional nose hair cutter 50.
Therefore, this feature will be described in detail below.

The base 62 is formed in a cylindrical shape, and is rotatably disposed at a portion of the main body case 52 where the head portion 56 is mounted. A joint 66 having a non-circular cross section attached to a rotating shaft 64 a of an electric motor 64 is provided on the lower surface of the base 62.
Is formed, and an insertion hole 14 for inserting the movable blade 12 is formed at the center of the upper surface. As an example, two movable blades 12 extend from the upper surface of the base 62. The movable blades 12 are opposed to each other and extend at equal angular intervals around the axis L of the base 62 (interval of 180 degrees because there are two). The plate-like spring member 12b constituting the movable blade 12 is provided with a base 62 for an opening prevention ring described later.
Restricting piece 1 for restricting movement to the side (root side of movable blade 12)
2c is protruded toward both sides. The position of the restriction piece 12c is determined by the blade 12a and the restriction piece 12 that constitute the movable blade 12.
The opening stop ring is set in accordance with the length of the opening stop ring so that the opening stop ring just fits between them.

The stop ring 16 is formed in a cylindrical body using a synthetic resin material, and functions as a stopper for the movable blade 12. The stop ring 16 is attached to all the movable blades 12.
One of the movable blades 12 is attached to the outer surface of the movable blade 12 so as to be bundled together.
Movement (opening of the blade portion 72a in the direction toward the inner peripheral surface of the fixed blade 58) with respect to the inner peripheral surface side of the fixed blade 58 with respect to the urging force of the plate spring members 12b. Regulations are made by bundling them together. Here, since the plurality of movable blades 12 have the same plate thickness and the same shape, the positions of the blade portions 12a of the movable blades 12 bundled by the retaining ring 16 are centered on the axis L. Will be located substantially on the same circumference.

When the movable blade 12 is inserted into or removed from the fixed blade 58, the inner diameter of the stop ring 16 is set at a position where the blade portion 12a at the tip of the movable blade 12 does not unnecessarily interfere with the fixed blade 58. It is set as follows. The method of attaching the opening prevention ring 16 to the movable blade 12 may be such that the movable blades 12 are simultaneously flexed in the direction of the axis L and simultaneously attached from the blade portion 12a side. After mounting, each movable blade 12 spreads outward by its own elastic force, and its outer surface opens and comes into contact with the inner surface of the stop ring 16. Further, since the shape of the blade portion 12a of each movable blade 12 is formed in a V-shape that expands outward as shown in FIG. 1, the opening prevention ring 16 once attached to the movable blade 12 can be easily formed. Does not come off the movable blade 12.

When the movable blade 12 is mounted inside the fixed blade 58 as shown in FIG. 1, the blade portion 12a comes into contact with the inner peripheral surface of the fixed blade 58, and the biasing force of the plate-like spring member 72b is applied. It slightly moves in the direction of the axis L in opposition. Accordingly, each leaf spring member 72b also moves slightly in the direction of the axis L from the position before the movable blade 12 is mounted in the fixed blade 58, so that the outer surface of the leaf spring member 72b and the inner surface of A gap is formed between the spring ring 72 and the leaf spring member 72.
b does not receive the biasing force from
Is in a state where it can freely move in the direction of the axis L and rotate independently of the movable blade 12, that is, a so-called floating state. Therefore, in this state, the plate-like spring member 72b is provided with a regulating piece 12c that abuts on the lower end of the opening ring 16 when the opening ring 16 is about to fall so that the opening ring 16 does not drop to the root side of the movable blade 12. ing.

When the movable blade 12 is mounted in the fixed blade 58 as described above, the opening prevention ring 16 is in a floating state with respect to the movable blade 12, The nose hair that has entered between the surface and the outer peripheral surface of the movable blade 12 has an appropriate inner peripheral surface of the opening prevention ring 16 and an outer peripheral surface (or side surface) of the movable blade 12 (specifically, the plate-like spring member 72b). By contacting it, it is scraped down and can be prevented from adhering to each. Therefore, it can be reduced that the cut pressure of the nose hair reduces the contact pressure of the blade portion 12a with the inner surface of the fixed blade 58, thereby reducing sharpness.

In the above-described embodiment, the movable blade 1
The number 2 is two, but in the case of three or more, the opening prevention ring 16 can be used similarly. Further, the shape of the opening prevention ring 16 may be an annular shape instead of the above-described cylindrical shape. In addition, the plane shape of the cylindrical body and the ring body is replaced with a circle,
It may be an ellipse or a polygon such as a quadrangle.

[0016]

According to the nose hair cutter according to the present invention, there is no plate-like stopper extending from the base as in the prior art, so that nose hair does not accumulate between the stopper and the movable blade. A decrease in taste can be suppressed. In particular, the retaining ring is simply fitted around a plurality of leaf spring members at once, so when the movable blade is mounted inside the fixed blade, it floats relative to the movable blade and The nose hairs between the inner peripheral surface of the stop ring and the outer peripheral surface of the movable blade are also scraped off and easily fall on the base. Therefore, there is an effect that it is difficult to be stained.
