Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a toothbrush, particularly a toothbrush used for cleaning dentures.

<Prior Art> Conventionally, this type of denture toothbrush had a soft brush and a hard brush implanted on the ventral back of one end of a single handle.

<Problems to be solved by the invention> Therefore, when using this type of conventional denture toothbrush for cleaning dentures, one of the brushes always wears out faster than the other. Even if one of the brushes is deformed and is still usable or has little wear, it must be discarded, and this tendency occurs regardless of the user. This problem occurred regardless of whether people used hard brushes or soft brushes. In addition, conventional denture toothbrushes
When using the denture with the denture in the mouth, the other brush gets in the way and cannot be used, and in such cases, it is necessary to keep another regular toothbrush on hand. It was hot.

Therefore, in order to solve these conventional problems, the present invention has two types of toothbrushes with different hardnesses, which can be used in the ventral dorsal position like conventional toothbrushes, but which can be separated individually. The conventional problem can be solved by making it possible to use the same.

<Means for Solving the Problems> The structure of the present invention for achieving the object will be explained using FIGS. 1 to 3 corresponding to the embodiments. brush part 1b
It consists of a toothbrush body 1 in which bristles are flocked, and a toothbrush subbody 2 in which a brush part 2b whose hardness is larger in proportion to the hardness of the brush part 1b in the toothbrush main body 1 is flocked in one end of the grip handle 2a. The grip handles 1a and 2a in 1 and 2 are formed to have approximately the same length, and the fitting portion 1 is formed over the entire length on the back side of each of these.
c and 2c so that they are removably fitted into each other.

<Function> Since the present invention has such a structure, when cleaning a denture outside the oral cavity which has been taken out from the oral cavity and immersed in a cleaning solution placed in a container, etc., it can be used as shown in Figure 1. When cleaning the denture in the oral cavity by fitting the hard and soft toothbrush bodies 1 and 2 together, and using the toothbrush parts 1a and 2a in different directions with the toothbrush parts 1a and 2a positioned on the ventral back,
The hard and soft toothbrush bodies 1 and 2 can be uncoupled and used as separate bodies.

<Examples> Examples of the present invention will be described below based on the drawings.

1 to 3 of the drawings show a first embodiment of the present invention, in which FIG. 1 shows a toothbrush main body 1 and a toothbrush subbody 2 fitted together, and FIGS. It is a diagram showing a state in which both bodies 1 and 2 are separated.
The toothbrush main body 1 has a brush portion 1b formed by implanting relatively soft bristles at one end of the grip handle 1a, the hardness of which is comparable to the hardness of the brush in a general toothbrush. As shown in FIG. 2, on the back side of 1a, a fitting portion 1c having a dovetail groove shape in plan view is formed along the entire length in the longitudinal direction. The toothbrush subbody 2 has a hard brush part 2b in which bristles harder than the toothbrush part 1b are implanted at one end of a grip handle 2a formed to have approximately the same length as the grip handle 1a of the toothbrush main body 1. On the back side of the grip handle 2a, a fitting part 2c having a dovetail-like protrusion in a plan view that fits with the fitting part 1c is formed along the entire length in the longitudinal direction. be.

When the denture is removed from the oral cavity for cleaning, the denture toothbrush constructed as described above has two hard and soft toothbrush parts, with both the toothbrush bodies 1 and 2 fitted together as one body, as shown in FIG. 1b and 2b are positioned on the ventral dorsum, and first, foreign substances with strong adhesion such as tartar formation adhering to the denture are removed with the hard brush part 2b, and then the entire denture is brushed with the soft brush part 1b.
Wash with water. At this time, unlike cleaning by switching between holding two toothbrushes, hard and soft,
Since the toothbrush can be cleaned by simply changing the direction of the toothbrush, the dentures can be cleaned very conveniently and quickly.

In addition, when it is difficult to remove the denture from the oral cavity and clean it due to time constraints, when brushing the denture in the oral cavity, as shown in FIG. The toothbrush body 1 can be used only by sliding it to release the fitting.

Figure 4 shows fitting parts 1c and 2c in both bodies 1 and 2.
This shows an embodiment in which the fitting part 1c in the toothbrush main body 1 is a channel-shaped groove in plan view, and the fitting part 2c in the toothbrush subbody 2 is a groove.
is a T-shaped protrusion in plan view.

Either of these fitting parts 1c, 2c may be groove-shaped and which one may be a protrusion, and these fitting parts are not limited to only groove-like and protrusion-like parts, but also include fitting holes. It may be a fitting structure with a fitting protrusion and a fitting projection, or it may be of other shapes, but both bodies 1 and 2 can be easily fitted and removed, and the brush part 1b of the toothbrush main body 1 can be easily fitted and removed in the separated position. It is important to have a structure in which the protrusion that protrudes largely toward the back side of the camera does not protrude.

FIGS. 5 and 6 show brush parts 1b and 2, respectively.
Fig. 5 shows another embodiment of Fig. 5, in which the brush portion 1b of the toothbrush body 1 is curved in a concave shape corresponding to the curvature of the teeth when viewed from the side (as shown in the figure). The brush portion 2b of the toothbrush subbody 2 is formed into a convexly curved shape when viewed from the side, so that it can be strongly rubbed with the abdomen. In the embodiment shown in FIG. 6, both toothbrush bodies 1 and 2 have brush parts 1b,
The side view shape of 2b, together with the shape of the tufting table portions 1a' and 2a', is formed into an inclined shape that protrudes outward toward the proximal side (downward side in the figure) compared to the tip side (upper side in the figure). The direction of the force at the time of the polishing is made to be inclined downward toward the tip, making it easier to perform the polishing operation. Further, the bristles of the brush portion 2b of the toothbrush subbody 2 are thicker than the bristles of the brush portion 1b of the toothbrush main body 1, and have a structure in which the bristles are coarsely flocked.

The figure shown in FIG. 7 shows a posture in which the brush parts 1b and 2b of both brush bodies 1 and 2 are fitted on the opposite sides of the grip handles 1a and 2a in the longitudinal direction. When used outside the oral cavity and inside the oral cavity, it is possible to save the effort of fitting and removing both bodies 1 and 2 one by one.

Although the embodiments considered to be representative of the present invention have been described above, the present invention is not necessarily limited to the structure of these embodiments, and the present invention is not necessarily limited to the structure of these embodiments. It can be implemented with appropriate modification within the scope of achieving the following effects.

<Effects of the invention> As is already clear from the above explanation, the invention has the following effects:
As a toothbrush for dentures, it has a structure in which a brush body with two types of brush parts of different hardness can be fitted together in a removable state, so when cleaning dentures outside the oral cavity, Even in the mated state, it is possible to perform cleaning operations with two different hardnesses in a state similar to a single brush.
In addition, when brushing teeth in the oral cavity, the two bodies can be unfitted and made into separate pieces, and only the toothbrush body can be used.Also, if necessary, the length of the handle can be changed to the length of the handle on the toothbrush body. There is an advantage that only the toothbrush accessory body, which is formed to have approximately the same length as the toothbrush body, can be used in a normal manner without any inconvenience.

Therefore, it is possible to brush teeth inside and outside the oral cavity without the need for a third toothbrush, and by integrating the toothbrush, one toothbrush will not be lost, and storage is convenient. If only one of the toothbrushes becomes worn or deformed or damaged, it is now possible to expect the economical effect that only that toothbrush needs to be purchased.
