JPH027902A - Cutter of hair in nostril - Google Patents

Abstract

PURPOSE:To prevent from injuring the mucous membrane of the nasal cavity when a cutter of hairs in the nostrils is inserted and to improve a cutting efficiency by covering a fixed blade with a comb and by projecting an edge part of a gullet of the fixed blade a little in a slot width of a slot part of the comb. CONSTITUTION:A fixed blade 8 of a comb-teeth shape, formed cylindrically with a periphery to be inserted into the nasal cavity and with a gullet 11 toward an axis, and a movable blade 7 rotating along the inside of the fixed blade 8 are provided. A comb 3 made from synthetic resin covering a periphery of the fixed blade 8 is also provided, projecting an edge pert 14 of a gullet 11 of the fixed blade 8 a little in a slot width (a) of a slot between a comb-teeth part 20 fo the comb 3. As a result, this cutter does not injure the mucous membrane when inserted into the nasal cavity, and is of a smooth touch and has a good cutting efficiency.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a nose hair cutter for cutting nose hair extending into the nasal cavity.

[Conventional technology]

2. Description of the Related Art Conventionally, there is a nose hair trimmer that is provided with a cylindrical comb-shaped fixed blade that is inserted into the nasal cavity. The fixed blade is made of metal and exposed, and the tip and the edge of the blade groove on the outer circumferential surface are processed into a smooth curved surface so as not to damage the mucous membrane of the nasal cavity.

[Problem to be solved by the invention]

However, since the hard metal fixed blade is inserted into the soft mucous membrane of the nasal cavity, even if it is smooth, it can be rough and unpleasant to the touch, and may damage the mucous membrane. Furthermore, since smooth machining is required, machining costs increase.

An object of the present invention is to provide a nose hair cutter that does not damage mucous membranes even when inserted into the nasal cavity, has a smooth feel, and has good cutting performance.

[Means to solve the problem]

The present invention provides a nose hair counter that includes a cylindrical, comb-shaped fixed blade that is inserted into the nasal cavity, and a movable blade that rotates along the inner surface of the fixed blade. It is equipped with a comb. The edge of the blade groove of the fixed blade is made to slightly protrude within the width of the groove of the comb.

[Function] According to the structure of the present invention, since the fixed blade is covered with a comb, when inserted into the nasal cavity, the fixed blade does not touch the mucous membrane, and only the comb touches the mucous membrane of the nasal cavity. The edge of the blade groove of the fixed blade slightly protrudes into the width of the comb groove, so cutting performance is good.

〔Example〕

A first embodiment of the present invention will be described based on FIGS. 1 to 6.

As shown in FIG. 2, a head case 2 is attached to the main body housing 1, and the tip of the head case 2 is formed into a cylindrical comb 3 having an outer diameter that can be inserted into the nasal cavity. 4 is a cap that is placed over the head part case 2. Comb 3 is
It is made of a synthetic resin with good processability and elasticity.

As shown in FIG. 1, the head part case 2 is removably fitted into the cylindrical part 1a of the main body housing l. A motor 5 and a battery (not shown) are housed in the main housing l. The fixed blade 8 is fixed to the inner circumference of the comb 3, and the movable blade 7, which rotates along the inner surface of the fixed blade 8, is attached to the movable blade stand 6. The movable blade stand 6 is removably fitted onto a joint 9 which is press-fitted onto the drive shaft 5a of the motor 5, and rotation is transmitted through the D-shaped cross section of the fitted portion.

As shown in FIG. 5, the fixed blade 8 has a cylindrical shape, and has a comb-teeth shape with a large number of blade grooves 11 formed along the axial direction. As shown in FIGS. 3 and 4, the comb tooth portion 20 of the comb 3 covers each comb tooth portion of the fixed blade 8.
The edge 14 of the blade groove 11 slightly protrudes into the groove width of the groove between the comb teeth 20 of the comb 3. In FIG. 3, a is the groove width of the comb, and b is the width of the blade groove 11 of the fixed blade 8.

As shown in FIG. 6, the movable blade 7 has a U-shaped arm portion 15.
A cutting edge 12 is provided at both ends of the blade.

The arm portion 15 is designed to expand freely, and its elasticity allows the cutting edge 1 to
2 and the fixed blade 8 to obtain contact pressure. The movable blade 7 can be attached to the movable blade stand 6 by fitting the hole 15a provided at the base end of the arm part 15 into the shaft part 6a of the movable blade stand 6 (FIG. 1).
The driving piece 16 provided near the tip of the arm portion 15 is engaged with the two-pronged tip retaining piece 6b of the shaft portion 6a to enable rotation transmission. A stopper 17 further extends from the driving piece 16 and is engaged with the inside of the tip retaining piece 6b.

The operation of the above configuration will be explained. When the comb 3 is inserted into the nasal cavity, nasal hair is introduced from the groove of the comb 3 into the blade groove 11 of the fixed blade 8, and is cut by being pinched between the movable blade 7 and the fixed blade 8, which rotate along the inner surface of the fixed blade 8. Ru. The edge portion 14 of the blade groove 11 of the fixed blade 8, which serves as a cutting edge, slightly protrudes into the groove portion of the comb 3, so that the nose hair is surely contacted and good cutting performance is obtained.

Since the outer periphery of the fixed blade 8 is covered with the comb 3, it does not touch the mucous membrane of the nasal cavity, and only the comb 3 touches it. Since the comb 3 is made of synthetic resin, it provides smooth contact with the mucous membranes and does not damage the mucous membranes.
Although the edge 14 of the fixed blade 8 protrudes into the groove of the comb 3,
Since the amount of protrusion is small, the fixed blade 8 does not touch the mucous membrane.

Since the head part case 2 is removably fitted into the cylindrical part 1a of the main body housing 1, the fixed blade 8 and the movable blade 7 can be cleaned by removing the head part case 2. In this case, the movable blade 7 is designed to apply contact pressure to the fixed blade 8 as it opens, but the stopper piece 17
Since the movable blade 7 is engaged with the inner surface of the tip engaging piece 6b of the movable blade stand 6, the movable blade 7 does not open more than necessary. Therefore, the head part case 2 is easy to attach and detach, and cleaning is easy.

7 to 9 show a second embodiment. This example is
The fixed blade 8' and the movable blade 7' have substantially similar cylindrical shapes. The difference in the inner diameter between the fixed blade 8' and the movable blade 7' is 30
The diameter is about μm to improve cutting performance. Movable blade 7'
A pair of engagement holes 7b are provided on the bottom surface and are engaged with the tip engagement piece 6b of the movable blade stand 6. Other structural effects are the same as in the first embodiment.

[Effects of the Invention] Since the nose hair cutter of the present invention covers the fixed blade with a comb, the fixed blade is prevented from touching the mucous membrane when inserted into the nasal cavity, and only the synthetic resin comb comes into contact with the mucous membrane. Therefore, it does not damage mucous membranes and provides a soft feel. The edge of the blade groove of the fixed blade protrudes within the width of the groove of the comb, resulting in good cutting performance, and since the amount of protrusion is small, the fixed blade does not come into contact with the mucous membrane.
