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 extending into a nasal cavity.

[0002]

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

[0003]

However, since a hard metal fixed blade is inserted into the nasal cavity of the soft mucous membrane, even if it is smooth-worked, it will be rough and uncomfortable and will damage the mucous membrane. was there. SUMMARY OF THE INVENTION An object of the present invention is to provide a nose hair cutter having a smooth feel without damaging mucous membranes even when inserted into a nasal cavity.

[0004]

SUMMARY OF THE INVENTION A nose hair cutter according to the present invention includes a comb-shaped fixed blade formed in a cylindrical shape and having an axial blade groove, and a movable blade rotating along an inner surface of the fixed blade. A comb made of synthetic resin having a comb tooth portion corresponding to each comb tooth of the fixed blade and covering the outer periphery of the fixed blade, wherein the tip of the comb tooth portion of the comb covers the tip of the comb tooth of the fixed blade. A curved part protrudes.

[0005]

According to the structure of the present invention, since the fixed blade is covered with the comb made of synthetic resin, the fixed blade does not touch the mucous membrane when inserted into the nasal cavity, and only the comb touches the mucous membrane of the nasal cavity. In addition, a bent portion that covers the tip of the comb teeth of the fixed blade protrudes from the tip of the comb teeth of the comb, so that when the tip of the fixed blade is inserted into the nasal cavity, the mucous membrane at the back of the soft nasal cavity is cylindrical. Of the fixed blade inserted into the nasal cavity is covered with a synthetic resin bend, so that the mucous membrane is not hurt by the tip of the fixed blade. As a result, the user can use the device without anxiety that the user will be hurt inside the nasal cavity by the tips of the comb teeth of the fixed blade.

[0006]

An embodiment of the present invention will be described with reference to FIGS. In this nose hair cutter, as shown in FIG. 2, a head case 2 is attached to a 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 a nasal cavity. Reference numeral 4 denotes a cap that covers the head case 2. The comb 3 is formed of an elastic synthetic resin having good workability.

As shown in FIG. 1, the head case 2 is detachably fitted to the cylindrical portion 1a of the main body housing 1.
A motor 5 and a battery (not shown) are housed in the main body housing 1. The fixed blade 8 is fixed to the inner periphery of the comb 3,
The movable blade 7 that rotates along the inner surface of the fixed blade 8 is
It is attached to. The movable blade base 6 includes a drive shaft 5 a of the motor 5.
The fitting 9 is press-fitted onto the fitting 9 so that it can be freely inserted and removed, and rotation is transmitted by the D-shaped cross-sectional shape of the fitting portion.

As shown in FIG. 5, the fixed blade 8 has a cylindrical shape, and has a plurality of blade grooves 11 along the axial direction, and has a comb-like shape. As shown in FIGS. 3 and 4, the comb teeth 20 of the comb 3 are provided corresponding to the respective comb teeth of the fixed blade 8, and the edge 14 of the blade groove 11 of the fixed blade 8 is It projects slightly within the groove width of the groove between the parts 20. In FIG. 3, a is the groove width of the comb 3, and b is the width of the blade groove 11 of the fixed blade 8. Further, a bent portion 20a is provided at the end of the comb teeth 20 of the comb 3 so as to cover the end of the comb teeth of the fixed blade 8.

As shown in FIG. 6, the movable blade 7 is provided with cutting blades 12 at both ends of a U-shaped arm portion 15. The arm portion 15 is designed to be freely spread, and its elasticity allows the cutting blade 12 to be used.
The contact pressure between the blade and the fixed blade 8 is obtained. Movable blade 7
The hole 15a provided at the base end of the arm 15 is
(FIG. 1) is mounted on the movable blade base 6 by being fitted to the shaft portion 6a of FIG. 1, and the driving piece 16 provided near the front end of the arm portion 15 is rotated by engaging the bifurcated front end engaging piece 6b of the shaft portion 6a. It can be transmitted. A stopper 17 is further extended from the drive piece 16 and is engaged with the inside of the distal end engagement piece 6b.

The operation of the above configuration will be described. When the comb 3 is inserted into the nasal cavity, the nose hair is introduced into the blade groove 11 of the fixed blade 8 from the groove of the comb 3 and cut by being sandwiched between the movable blade 7 and the fixed blade 8 rotating along the inner surface of the fixed blade 8. You. Fixed blade 8
Since the edge portion 14 serving as the cutting edge of the blade groove 11 slightly projects into the groove portion of the comb 3, the nose hair surely hits and good cutting properties can be obtained.

Since the outer periphery of the fixed blade 8 is covered with the comb 3, only the comb 3 does not touch the mucous membrane of the nasal cavity. Since the comb 3 is formed of a synthetic resin, a smooth feel to the mucous membrane can be obtained and the mucous membrane is not damaged. Although the edge 14 of the fixed blade 8 protrudes into the groove of the comb 3, the amount of protrusion is small, so that the fixed blade 8 does not touch the mucous membrane. Furthermore, since the bent portion 20a that covers the tip of the comb tooth of the fixed blade 8 protrudes from the tip of the comb tooth portion 20 of the comb 3, when the tip of the fixed blade 8 is inserted into the nasal cavity, the back of the soft nasal cavity is formed. Mucous membrane does not enter the inside of the cylindrical fixed blade 8 and damage the mucous membrane at the tip of the comb tooth of the fixed blade 8, and the tip of the comb tooth of the fixed blade 8 inserted into the nasal cavity is made of synthetic resin. Can be safely used without the user having anxiety that the tip of the comb teeth of the fixed blade 8 may damage the nasal cavity.

Since the head case 2 is detachably fitted to the cylindrical portion 1a of the main body housing 1, the fixed blade 8 and the movable blade 7 can be cleaned by extracting the head case 2. In this case, the movable blade 7 is configured to apply a contact pressure to the fixed blade 8 as it is opened. However, since the movable blade 7 is engaged with the inner surface of the tip engaging piece 6b of the movable blade base 6 by the stopper piece 17, it is necessary. As described above, the movable blade 7 does not open. Therefore, attachment and detachment of the head unit case 2 is easy, and cleaning is easy.

[0013]

According to the nose hair cutter of the present invention, since the fixed blade is covered with the synthetic resin comb, the fixed blade does not touch the mucous membrane when inserted into the nasal cavity, and only the synthetic resin comb is applied to the nasal mucosa. touch. Therefore, a smooth feel can be obtained without damaging the mucous membrane. In addition, a bent portion that covers the tip of the comb teeth of the fixed blade protrudes from the tip of the comb teeth of the comb, so that when the tip of the fixed blade is inserted into the nasal cavity, the mucous membrane at the back of the soft nasal cavity is cylindrical. Inside the fixed blade of
The mucous membrane is not hurt by the tips of the fixed-blade comb teeth, and the fixed-tooth tips of the fixed blade to be inserted into the nasal cavity are covered and hidden by a synthetic resin bent part, so that the user can fix it. It is safe to use without having to worry about injuring the nasal cavity with the tip of the comb teeth.
