Description

Toothbrush

The present invention relates to a toothbrush, and more particularly, to a toothbrush that has a light toothbrush down the center of gravity and is fixed to the floor to prevent the toothbrush from turning, while the bristles do not touch the floor.

Toothbrushes, which are widely used in general, are composed of a head having a fixed length and a bristles to hold by hand, and are an essential hygiene tool for oral hygiene. It is a tool to clean the.

Conventional toothbrushes have a rectangular bar shape that is divided into bristles and handles, and after the toothbrush is used, the bristles should be dried quickly and kept so dried to prevent the bristles from being contaminated by bacteria.

However, when the conventional toothbrush is placed on the floor instead of a separate toothbrush storage means, bristles or contaminates the bristles due to contaminants or water on the floor while the floor and the bristles touch.

As a result, the user of the toothbrush feels psychological discomfort and anxiety about contamination of the brush head.

According to Utility Model Registration No. 2004-25089, which was devised to solve such a problem, in the toothbrush provided with the bristles and the handle as shown in FIG. 1, the spherical body of the handle corresponding to the bristles was formed. It has a center of gravity installed in the lower end of the weight body.

In addition, according to Utility Model Registration No. 2003-5559, a head portion having a sole body, a neck portion extending from the lower end of the head portion, and a handle portion extending and connected to the head portion with the neck portion therebetween. In the conventional toothbrush made of, connected to the lower portion of the neck portion is gradually expanded in diameter while the lower end forms a round spherical shape (sphere), the inside of the weight based on the transverse centerline, the weight body is embedded in the lower side It is characterized by consisting of the handle portion formed.

However, the above method has a disadvantage in that it is inconvenient for the elderly to use the weak wrist strength due to the increase in the weight of the toothbrush according to the purchase of a separate weight.

The present invention has been made to solve the conventional problems as described above, even if you put the toothbrush in any direction to prevent the back of the toothbrush to move the center of gravity down to a light toothbrush, the toothbrush body is fixed to the floor but the bristles do not touch the floor To provide a toothbrush.

Toothbrush according to the present invention for achieving the above object, in the toothbrush consisting of a head portion coupled to the bristles, a neck portion extending from the head portion, a handle portion extending from the neck portion, the neck portion and Between the handle portion is provided with a protrusion formed protruding forward and backward and extending in the left and right direction, the end of the handle portion connected to the protrusion is formed in a flat flat portion so that the cross section of the protrusion and the handle portion of the toothbrush is formed in an oval shape, A backing protrusion is formed on the rear surface of the flat portion.

In addition, in the toothbrush according to the present invention, the protrusion is formed of a front protrusion and a rear protrusion, characterized in that formed to be offset from each other with respect to the center line connecting the neck portion and the handle portion.

In addition, in the toothbrush according to the present invention, the front surface portion of the handle portion connected to the protrusion is characterized in that the anti-slip microprotrusion is formed.

On the other hand, another toothbrush according to the present invention, in the toothbrush consisting of a head portion coupled to the bristles, a neck portion extending from the head portion, and a handle portion extending from the neck portion, between the neck portion and the handle portion A plate-shaped protrusion is formed to protrude around, and the length of the handle portion coupled to the protrusion extends longer than the length of the neck portion coupled to the protrusion so that the bristles do not touch the floor.

In addition, in the toothbrush according to the present invention, the centerline of the neck portion connected to the plate-like protrusion and the centerline of the handle portion connected to the plate-like protrusion are arranged to be offset from each other.

In addition, in the toothbrush according to the present invention, the neck portion is coupled to the outer circumferential surface from the center of the plate-shaped protrusions in front of the front surface, the handle portion is characterized in that the coupling at the same position corresponding to the back surface of the protrusions.

In addition, in the toothbrush according to the present invention, the neck portion and the plate-shaped protrusion coupled to the handle portion are characterized in that the neck portion and the handle portion is obliquely coupled.

On the other hand, another toothbrush according to the present invention, in the toothbrush consisting of a head portion coupled to the bristles, a neck portion extending from the head portion, and a handle portion extending from the neck portion, from the boundary between the neck portion and the handle portion The handle portion toward the end portion of the handle portion is formed so that its cross section is tapered in a conical shape is characterized in that the bristles do not touch the floor.

According to the toothbrush according to the present invention, the handle portion of the toothbrush is rounded so that the bristles do not touch the floor in any direction so as to separate from the contamination by the washbasin pollutants and water.

In addition, the round handle portion of the toothbrush of the present invention has an effect of facilitating the utilization and direction of the force when using the toothbrush to give a material and form deformation.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
