Description

Rotary nose shaver and fixed blade and its products {Rotary and Manual type Nostrils Hair Trimmer, and Trimming Blade}

The present invention relates to a nose shaver for cutting the nose hair, using a rotary blade, but without a motor and a battery, by rotating the rotary blade associated with the rotary blade to the left and right by rotating the rotary blade to the left and right to rotate the rotary blade. In that,

In particular, the rotary knob is located directly below the rotary blade and the grip portion is formed in the lower part of the body, so that the nose blade can be cut by rotating the rotary blade by moving only the thumb and index finger while holding it with one hand. It is characterized by matching according to structure and function.

Nose hair shavers generally include nose hair scissors or a manual rotary nose hair shaver and an electric nose hair shaver. Nose hair scissors use round-shaped scissors to prevent them from sticking inside the nose, and the most problematic problem when cutting with these scissors is that the cut nose hair may be scattered from inside the nose or sucked inward when breathing. In use, the clipped nose hairs will remain inside the stationary blade.

Manual rotary nose hair shaver as U.S. patent U.S. PAT 5,655,301 U.S. PAT D376,670 consists of a manual rotary blade with a handle that can turn the rotary blade at the lower end of the nose hair shaver and a number of cutting blades that protrude sharply forward to insert the nose hair at the top. There is a risk of injury inside the nose, and there is also a rotating knob installed on the lower part of the body. When using it, you must use both hands to hold the center of the body with one hand and turn the rotary knob attached to the lower end of the body with the other hand. It is more inconvenient to use than can be operated by hand.

In addition, the nose hair shaver composed of the electric motor is often inconvenient to change the battery and noise is high in use, and it is expensive, and it is necessary to make the nose hair powder by breathing at high speed unnecessarily. There is a tendency.

Therefore, the object of the present invention is to propose a new type of manual nose nose shaving device, but to rotate the nose hair by manual but not using the motor and battery, but holding the nose hair shaver with one hand without using both hands. By operating the rotary knob using the thumb or black only, the fixed blade and the inscribed rotary blade rotate to cut the nose hair.

First of all, in order to achieve this object, in order to simultaneously hold and rotate with one hand, the configuration of the manual rotary nose shaver must match the structure and function of the hand. If the rotary knob is located at the bottom of the manual rotary nose shaver, it cannot be operated with one hand and two hands must be used. Therefore, the rotary knob that turns the rotary blade of the nose hair shaver must be brought directly under the rotary blade, and the lower part of the body forms a grip part that can be held by one hand, so that the thumb and index finger are simply moved while the nose hair is held with one hand. The purpose of cutting the nose hair can be achieved by rotating the rotary blade. Therefore, an object of the present invention is to maximize the ease of use by ergonomically suitable in the construction of the device.

The nose hair is also divided into long stretches from deep inside the nose and growing at the mouth. In other words, the angle formed by the nose shaver into the nose to cut the nose hair is required to be formed horizontally and vertically. Therefore, the fixed blade and the rotary blade for cutting the nose hair need a blade formed at the same time horizontally and vertically.

This blade allows the nose around the nose and the nose around the nose to be cut at the same time can be cut at the same time to achieve a simple purpose.

Therefore, in the fixed blade, the blade surface is formed on one side of the circumference of the cylinder, and the cutting blade surface is formed successively on the surface perpendicular to the axis of the cylinder while contacting the end thereof, and the angle of the cylinder is formed around the cylinder to form an angle that opens. On the surface perpendicular to each other, forming a receding angle to face the rotary blade inside, so that the nose hair can be cut off more easily by cutting the nose hair like scissors, so that the nose hair can be cut more easily. To form a fixed blade of the nose shaver, characterized in that to be cut,

A blade contacting both the inner surface of the blade surface around the cylinder of the fixed blade and the blade surface of the inner surface of the surface perpendicular to the axis of the cylinder is successively formed, thereby forming a rotary blade so that the nose hair can be cut in two sides.

In addition, when the structure of the pointed scissors or the rotary blades with a number of tips touch the skin inside the nose directly, if the hand movement is a little incomplete, the inside of the nose can be easily injured. Do not touch. As described above, the blade bent in two sides can be used safely without damaging the inside of the nose regardless of the user's carelessness because the blade tip is not sharp.

The nose hair cut off by the front surface of the fixed blade can be easily shaken off without the cleaning process by disassembling the device, and the nose hair can be cleaned more conveniently by incorporating a cleaning brush in the lower body.

In addition, the rotation of the nose shaver to rotate only one direction irrespective of the operating direction of the rotary knob, install a torsion spring slightly smaller in diameter than the outer diameter of the shaft at the end of the cylindrical shaft coupled to the rotary blade, and rotates the end of the torsion spring By engaging the bottom of the blade, the rotary blade can be rotated in only one direction.

In addition, it is economical because it does not require consumables such as batteries, and it can be commercialized at the minimum manufacturing cost by making an extremely simple structure.
