How to make a new nose hair trimmer

The nose hair trimmer is a special beauty tool that can be inserted into the nostrils to trim the long nose hair. Common electric nose hair trimmers include a body, and the body is provided with a motor, a corresponding transmission mechanism, and a movable blade and a fixed blade that cooperate with each other. The nose hair trimmer can be divided into two categories according to the different movement modes of the movable blade. One is that the movable blade rotates relative to the fixed blade; the other is the movable blade. Reciprocate laterally relative to the fixed blade (at this time, the movable blade moves perpendicular to the depth of the nasal cavity). These two types of electric nose hair trimmers are very fast and convenient to trim nose hair, but the movable blades rotate or move back and forth in the working plane perpendicular to the depth direction of the nasal cavity, which will affect the fixed blades during work, thereby repeatedly hitting the inner wall of the nasal cavity, which This kind of impact is relatively strong for the weak nasal cavity, and it is easy to cause nasal discomfort and even injury to the nose. In addition, the aforementioned trimmers are not ideal for trimming and shaving nose hair.

SUMMARY OF THE UTILITY MODEL In order to solve the defects in the prior art, the present invention provides a fast and efficient nose hair trimmer which can change the installation position and movement mode of the blade, which will not hit the inner wall of the nasal cavity during operation, and feel more comfortable and efficient when shaving nose hair. Improves trimming and shaving without hurting your nose.

The technical scheme of the utility model is a novel nose hair trimmer, which comprises a body including a holding section and a blade mounting section, the upper part of the body is the blade mounting section, the lower part is the holding section, and the body is provided with a motor and a blade assembly, which is characterized by: The blade assembly includes a fixed blade located in the blade installation end and arranged along the axis of the body, and a movable blade that cooperates with it and can move back and forth along the axis of the body. It is connected with the output end of the motor, and the blade mounting section is provided with a working opening of the blade assembly. The utility model changes the previous plane movement mode of the blade in the direction perpendicular to the depth of the nasal cavity, and drives the movable blade to move back and forth along the axis direction of the body through the transmission mechanism to cooperate with the fixed blade, so as to realize the movement along the depth direction of the nasal cavity and trim the nose hair without hitting the inner wall of the nasal cavity. Avoid discomfort and prevent nose injury from impact. Since the blade assembly trims the nose hair in a direction substantially parallel to the nasal cavity, the nose hair corresponding to the length of the blade can be effectively trimmed, thereby improving the cleanness of shaving.

The transmission mechanism described in the utility model comprises two matching main and auxiliary bevel gears, wherein the main bevel gear is connected with the motor output shaft, the auxiliary bevel gear is connected with an eccentric wheel, and the eccentric wheel is connected with an eccentric wheel that drives the movable blade to move. A transmission rod, the other end of which is connected with the lower end of the movable blade. The motor drives the eccentric wheel to rotate through the output of the bevel gear, and relies on the eccentric wheel to drive the transmission rod to make the movable blade move back and forth, so as to move and trim the nose hair along the depth direction of the nasal cavity. The entire transmission mechanism is compact and easy to install in the slender body.

The movable blade described in the utility model is provided with two spaced limiting grooves along the direction thereof, and corresponding upper and lower guide blocks are arranged in the body. A plurality of distributed guide blocks and limit grooves cooperate to limit the position of the movable blade, so as to ensure the stable movement of the movable blade along the axis direction of the body, and to facilitate manufacturing and processing.

In the upper and lower guide blocks described in the utility model, the cross-section of the upper guide block near the top of the main body is "cross" shape, the vertical part of which is parallel to the axis of the main body, and the cross-section of the lower guide block is rectangular. The movement of the movable blade is limited by the transverse part of the "cross"-shaped guide block. Since the guide block is very small, in order to ensure its working strength, a vertical intersecting vertical part is set to enhance its working strength, which is not easy to break and is reliable in use.

Both sides of the movable blade and the fixed blade described in the utility model are provided with cutting edges, and the two sides of the blade installation section are provided with corresponding working openings. Because there are working openings for trimming nose hair on both sides, just turn 90 degrees clockwise or counterclockwise to achieve 360-degree circumferential trimming of excessively long nose hair on the inner surface of the nasal cavity. It needs one rotation to achieve 360-degree circumferential trimming of nose hair, which has higher work efficiency and shorter trimming process.

A plurality of parallel protective ridges are distributed along the circumferential direction on the outer surface of the blade installation section corresponding to the working opening in the utility model. During the working process of the blade assembly, the convex protective ridges first touch the inner wall of the nasal cavity to ensure that there is a gap between the blade and the inner wall of the nasal cavity to avoid direct contact between the blade and the inner wall of the nasal cavity. Safe and secure.

The utility model realizes the nose hair trimming along the depth direction of the nasal cavity by arranging a movable blade that can move along the axis of the body to cooperate with the fixed blade installed in the same direction, and avoids the working plane of the blade perpendicular to the depth direction of the nasal cavity when the existing nose hair trimmer works. The impact of the impact of the internal movement on the nasal cavity is safer to use, the trimming effect is better, and the human body feels more comfortable.
