Description

[0001] The present invention relates to a toothbrush with replaceable brush section,

More particularly, the present invention relates to a toothbrush replacement type toothbrush, and more particularly, to a toothbrush replacement type toothbrush, which is capable of binding a toothbrush head and a bristle easily and stably by tying a trapezoidal groove-shaped rail portion of a toothbrush head and a binding portion of a trapezoid- Gt; toothbrush < / RTI >

Generally, a toothbrush is a sanitary tool used to keep the inside of the mouth and the teeth clean.

Such a toothbrush is made of various kinds of toothbrushes depending on the age and the condition of the user, and generally comprises a handgrip and a toothbrush head formed with bristles. Such a toothbrush is used for rubbing a tooth, a gum, a tongue, etc., by grasping a handle and a toothbrush with a toothbrush.

The toothbrush used in this way is frequently replaced because wear and deformation of the bristles, various bacteria, and so on may cause damage to the inside of the mouth and the health of the teeth.

As described above, frequent replacement of toothbrushes has problems such as non-economic problems as well as various environmental pollution due to an increase in disposal amount of synthetic resin material.

To improve this, a toothbrush head of a conventional toothbrush is configured to be assembled on a handle and a toothbrush head is replaced with only a toothbrush head.

For example, the bristles are formed to have a thickness of the head portion and press-fit into the insertion hole at the center of the head. However, the replacement of the bristles is inconvenient and the bristles are not stably bound to the toothbrush head.

In addition, the conventional toothbrush has a problem that foreign matter is caught between the bristles and is difficult to remove easily.

One aspect of the present invention provides a toothbrush replaceable toothbrush capable of binding the toothbrush head and the bristles easily and stably by binding the rail portion of the trapezoidal groove shape of the toothbrush head and the binding portion of the trapezoidal projection shape of the bristles in a sliding manner It is on.

Another aspect of the present invention is to provide a bristle interchangeable toothbrush wherein bristles can be separated from each other by unit bristles to easily remove foreign substances sandwiched between bristles.

A toothbrush replacement type toothbrush according to an embodiment of the present invention includes: a toothbrush handle; a tongue scratching portion formed integrally with the toothbrush handle at a head portion of the toothbrush handle, the tongue scratching portion formed on a top surface of the toothbrush handle, The toothbrush of claim 1, further comprising: a toothbrush head having a rail portion with a width gradually increasing from a lower side toward an upper side in a direction from the lower side to the upper side, And a bristle having a fastening portion that is gradually widened and has a fastening protrusion formed at an upper edge thereof.

Also, the bristles are comprised of unit bristles that are connected by a wire to each other to selectively form a separate or non-separable state, wherein the bristle interchangeable toothbrush is configured to either restrain or decouple the wire to remove any of the unit bristles And a stopper for pulling the unit bristles to separate or non-separate the unit bristles.

In addition, the stopper restrains the wire at the engagement position of the 'A' -shaped sliding groove of the toothbrush handle so that the unit bristles are not separated from each other, and at the engagement release position of the 'A' -shaped sliding groove of the toothbrush handle And a fixing protrusion releasing the wire so that the unit bristles are separated from each other.

The stopper may include an operating rod provided at one end of the holder coupled to the wire for restraining or restraining the wire while being operated in a space between the cut portions of the toothbrush handle, And a handle for moving the operating rod while being moved.

Therefore, the bristle interchangeable toothbrush according to the embodiment of the present invention can easily and stably bind the toothbrush head and the bristles by tying the trapezoidal groove-shaped rail portion of the toothbrush head and the binding portion of the trapezoidal projection shape of the bristles in a sliding manner It is effective.

In addition, the bristle replacement type toothbrush according to the embodiment of the present invention has the effect that the brush bristles are made of detachable unit bristles to easily remove the foreign substances between the bristles.

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

FIG. 1 is a perspective view of a bristle interchangeable toothbrush according to an embodiment of the present invention. FIG. 2 is a perspective view of the bristle interchangeable toothbrush shown in FIG. 1, ≪ / RTI > wherein the toothbrush is a toothbrush.

1 to 3, a bristles interchangeable toothbrush 10a according to an embodiment of the present invention includes a toothbrush holder 100, and a toothbrush holder 100 integrally formed with the toothbrush holder 100 at a head portion of the toothbrush holder 100 The tongue scratch 210 is formed on the upper surface of the toothbrush 100. The tongue scratch 210 is formed on the upper surface of the toothbrush 100. The width of the tongue scratch 210 is gradually widened from the lower side toward the upper side in the direction of forming the toothbrush pedestal 100, The width of the toothbrush head 200 having the part 220 gradually widens from the lower side to the upper side so as to correspond to the engaging groove 221 for sliding engagement with the rail 220 of the toothbrush head 200, (300) having a coupling portion (310) formed with a locking protrusion (311).

The toothbrush holder 100 is formed in a plate shape having a predetermined thickness so that the user can hold the toothbrush 10a by hand.

The toothbrush head 200 is integrally formed with the toothbrush head 100 at the head of the toothbrush head 100. The toothbrush head 200 is integrally formed with a tongue-like scratching portion 210 in the shape of a washboard.

At the center of the bottom of the toothbrush head 200, a rail 220 having a trapezoidal groove shape is formed in a direction in which the toothbrush table 100 is formed.

The width of the rail 220 is gradually widened from the lower side toward the upper side, and the latch groove 221 is formed at the upper edge.

The toothbrush head 200 is detachably coupled to the bristles 300 such that the bristles 300 include a bristle portion 320 and a toothbrush plate 330.

A coupling portion 310 having a trapezoidal protrusion shape is formed in the toothbrush plate portion 330 at a top center thereof so as to be bound to the rail portion 220 of the toothbrush head 200.

The upper and lower sides of the binding portion 310 are formed in a trapezoidal shape in which the width is gradually widened from the lower side to the upper side so as to have a shape to be in contact with the shape of the rail 220. A hooking jaw 311 is formed at the upper corner do.

The bristles 300 having the binding portion 310 are positioned at one end of the toothbrush head 200 and one side of the binding portion 310 of the bristles 300 is inserted into the end of the rail 220 of the toothbrush head 200 So that the bristles 300 are slid into the rail 220 and inserted into the other rail 220 of the coupling part 310 to be engaged.

The bristles 300 bound to the rails 220 of the toothbrush head 200 can be engaged or disengaged while being guided by the binding portion 310 and sliding left and right on the rail 220. [

Therefore, when a strong force is applied to the bristles 300, since the binding portion 310 of the bristles 300 and the upper portion of the rail portion 220 of the toothbrush head are formed to have a wider width, Since the engaging jaw 311 is caught by the engaging groove 221 formed in the rail part of the toothbrush head 200 and the binding part 310 is not drawn out from the rail part 220, the bristles 300 are separated from the toothbrush head 200 There is no fear of becoming.

The bristles 300 can be conveniently attached to the lower end of the toothbrush head 200 while the brush bristles 300 are in close contact with each other, So that the toothbrush head 200 and the bristles 300 can be sanitized because toothpaste and foreign substances do not flow in between the toothbrush head 200 and the bristles 300.

Another embodiment of the present invention will be described with reference to Figs. 4 and 5. Fig. The same reference numerals are assigned to the same components as those of the above-described embodiment, and a description thereof will be omitted.
