1 to 3, the toothbrush 10 according to an embodiment of the present invention, the toothbrush body 100 to provide a plurality of separated head portion 120, and the plurality of separated head portion It may include a moving piece 200 that can be in close contact with each other by pressing the 120.

In detail, the toothbrush body 100 may quickly dry the moisture on the bristles of the head part 120 by securing a space between the head parts 120 through the plurality of separated head parts 120. . For example, the user may brush teeth in a state in which the plurality of head portions 120 are collected, and after brushing is finished, the user opens (separates) the plurality of head portions 120 and the surface area of the bristles in contact with air. By widening, the rate of moisture drying for bristles can be increased.

To this end, the toothbrush body 100 may include a body portion 110, a head portion 120, a bristle portion 130 and a guide groove 140. Here, the body portion 110 may be manufactured in the form of a convex bar that can be gripped by the user. The grip protrusion and grip grooves of various shapes may be formed on the surface of the body part 110 for a stable grip.

In addition, the head part 120 may extend in one end of the body part 110 and may be provided in a shape including a plurality of beams. In this case, the plurality of separated beams constituting the head part 120 may be provided in a form of being separated from each other as the body part 110 moves away from the body part 110.

For example, the head part 120 includes the first head part 121 extending from the center of the tip end of the body part 110 and the body part 110 such that the tip is spaced apart in one direction from the tip of the first head part 121. The second head portion 122 that extends from one side of the tip, and the third head portion 123 that extends from the other end of the body portion 110 so that the tip is spaced apart from the tip of the first head 121 in the other direction. It can be composed of).

In this case, first and second protrusions 121a and 121b may be formed on both side surfaces of the first head 121, respectively. In addition, a first recess 122a that can be inserted into the first protrusion 121a is formed on one side of the second head 122, and a second protrusion 121b is inserted into one side of the third head 123. Possible second recesses 123a may be formed. Accordingly, when the moving piece 200 is moved to the head part 120, the first protrusion 121a and the second protrusion 121b are formed in the first recess 122a and the first head 122 of the second head part 122. 2 grooves (123a) may be inserted and seated respectively.

The second head part 122 may be made of a flexible plastic (synthetic resin) material that may be in close contact with one side of the first head part 121 by the pressing of the moving piece 200. The third head part 123 may also be made of a flexible plastic material that can be in close contact with the other side of the first head part 121 by the pressing of the moving piece 200.

In the present embodiment, the contents of the second head portion 122 and the third head portion 123 are made of a flexible plastic material, but the present invention is not limited thereto, and the second head portion 122 and the third head portion 122 are described. Of course, the configuration other than the head 123 may be made of a flexible plastic material.

The bristle part 130 may be provided at each head part 120, more specifically, the first head part 121, the second head part 122, and the second head part 122. The bristle part 130 may be formed of a plurality of bristles. The plurality of bristles may be of a configuration corresponding to the bristles used in conventional toothbrushes.

The guide groove 140 may extend from the side of the body 110 to the side of the head 120 along the longitudinal direction of the toothbrush body 100 to guide the movement of the moving piece 200. For example, the guide groove 140 may include a first groove 141 formed on both sides of the body 110, and a second groove 142 formed on the outermost sides of the head 120. The channel part 143 may connect the first groove part 141 and the second groove part 142 to each other.

At this time, the first groove portion 141 and the second groove portion 142 has a depth corresponding to the thickness of the guide protrusion 210 protruding from the inner surface of the moving piece 200, the channel portion 143 is the first groove portion It has a depth shallower than the depth of 141 and the second groove 142.

Accordingly, when the moving piece 200 is completed moving to the body part 110, the guide protrusion 210 of the moving piece 200 may be seated in the first groove part 141 of the body part 110. When the moving piece 200 is moved to the head part 120, the guide protrusion 210 of the moving piece 200 may be seated in the second groove part 142 of the head part 120. In addition, in order for the moving piece 200 to move to the head part 120 or the body part 110, the guide protrusion 210 of the moving piece 200 may be guided in a state of being inserted into the channel part 143. .

The moving piece 200 may be provided in the form of a square ring that is movable along the longitudinal direction of the toothbrush body 100. When the moving piece 200 is moved from the body part 110 of the toothbrush body 100 to the head part 120, the moving piece 200 presses the plurality of separated head parts 120, thereby between the plurality of head parts 120. It can be in close contact with each other.

The guide protrusion 210 may protrude from the inner surface of the moving piece 200. The guide protrusion 210 may guide the moving direction of the moving piece 200 while moving along the guide groove 140 of the toothbrush body 100 when the moving piece 200 moves.

 Referring to the operation of the present invention made of such a configuration as follows.

Figure 4 is a state diagram showing the state of the toothbrush when the moving piece is moved to the head portion of the toothbrush body in one embodiment of the present invention, Figure 5 is, in one embodiment of the present invention, the moving piece moves to the body portion of the toothbrush body Is a state diagram showing the state of the toothbrush.

As shown in FIG. 4, when the user intends to brush teeth using a toothbrush, the user moves the moving piece 200 to the head portion of the body 110 of the toothbrush body 100 while holding the toothbrush body 100. When moving to 120, while the plurality of heads 120 closely contact each other, the plurality of heads 120 may form one head 120. At this time, the user can brush their teeth conveniently through the brush head 130 collected as one.

As shown in FIG. 5, when brushing is completed, when the user moves the moving piece 200 from the head part 120 of the toothbrush body 100 to the body part 110, the plurality of head parts 120 may be formed. While restored to its original form, the plurality of head portions 120 may be spaced apart from each other.

At this time, since each space between the bristles of the head portion 120 is formed to move the air smoothly, drying of the bristles proceeds quickly to maintain a hygienic clean state of the toothbrush, the head portion of the 120 It is easy to remove debris between the bristles.

The embodiments described above are merely illustrative of some examples of the present technical idea, and the scope of the present technical idea is not limited to the described embodiments, within the scope of the present technical idea by those skilled in the art. Various changes, modifications, or substitutions of will be possible and all such implementations should be regarded as falling within the scope of the present invention.
