BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toothbrush for cleaning teeth and gums, and more particularly, to a toothbrush for cleaning teeth and gums, which can wipe the tooth surface, the lingual surface, the occlusal surface, the teeth, and the gingival fissure simultaneously.

A typical tooth care method is brushing using a toothbrush. The toothbrush is a means for brushing toothbrushes, which are planted in the head portion, with toothpaste to clean teeth with tooth surfaces of teeth.

As is known to those skilled in the art, a toothbrush may cleanly wipe the outer surface of a tooth ("sagging", also referred to as posterior teeth or anterior teeth) and the occlusal surface (the surface between the upper and lower teeth) The inner surface (the surface of the snow) can not be wiped easily and cleanly.

In addition, a general toothbrush can remove a significant amount of foreign material caught between the teeth while brushing in the lateral direction along the dentition, but there is a limit to completely removing the fibers or plaques. Patent Document 1 proposes a toothbrush capable of easily removing foreign matter such as plaque or food waste remaining in teeth by digging into a gap between teeth through the height difference of the bristles. The toothbrush according to Patent Document 1 is equipped with bristles having different heights so as to provide a cleaning effect between the teeth, but such bristles do not clean the dorsal surface of a tooth having a relatively high incidence of tooth decay as described above.

In this specification, the terms first, second, etc. are used to distinguish one element from another, and the element is not limited by the terms. In the accompanying drawings, some of the elements are exaggerated, omitted or schematically shown, and the size of each element does not entirely reflect the actual size.

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

1 and 2, a toothbrush for cleaning crown and gum according to a preferred embodiment of the present invention includes a handle 100 and a head 200 disposed at one end of the handle 100 have. The handle portion 100 is elongated in one shape.

As shown in the figure, the head part 200 bristles bristles extending in multiple directions at one end of the handle part 100.

The toothbrush for cleaning teeth and gums according to a preferred embodiment of the present invention is provided with an inner side surface of a head portion 200 for allowing the bristles to penetrate into the interdental spaces and to contact the bristles at the gingival perforations simultaneously while wiping the surfaces of the teeth, The bristles are loaded from the base 210, the first sidewall 220, and the second sidewall 230 toward the space 240.

Specifically, the head unit 200 includes a base 210, a first sidewall 220 extending upward from the front end of the base 210, and a rear end of the base 210 opposite to the first sidewall 220. [ And a second sidewall 230 extending upward from the side of the first sidewall. As a result, the head unit 200 is formed in a U-shaped structure and surrounds the teeth.

In addition, the present invention opens both side surfaces of the head part 200, that is, the left and right side surfaces, corresponding to the dentition forming direction. The head portion 200 opens both sides of the handle portion 100 in a direction orthogonal to the axial direction of the handle portion 100 and accommodates a part of teeth of a plurality of teeth in the space 240 of the head portion 200 While brushing forward and backward in the axial direction of the knob portion 100, the bristles are moved back and forth in the normal direction of the dentition, that is, in the direction perpendicular to the nose surface and the snowy surface.

The head portion 200 forms a space 240 defined by the base 210 and the first sidewall 220 and the second sidewall 230. The head portion 200 is configured to position the bristles as shown, Thereby providing a space 240 in which the teeth can be accommodated.

Preferably, the space 240 can accommodate one to two teeth of the molar reference, and accordingly, the width of the head portion 200 in the dentition direction has a width enough to accommodate one to two teeth or two teeth on the basis of the molar .

The head portion 200 can interpose the first refraction portion 250 between the base 210 and the first sidewall 220. The first refracting portion 250 provides flexibility to allow the first sidewall 220 extending upward from the front end of the base 210 to flow at a predetermined angle. During the brushing, the first side wall 220 is allowed to move in the anteroposterior direction in response to the external force applied to the tooth or the teeth.

The head portion 200 of the present invention includes a base 210, a first sidewall 220, and a second sidewall 230 (not shown) on the inner side of the head portion 200, To the space 240. In this way, The base 210 covers the vertical bristles 310 on its inner side.

The first sidewall 220 includes a first horizontal bristle 321 and a first tilted bristle 322 on the inner side thereof and includes an array of first horizontal bristles 321 and first tilting bristles 322, The height can be different. The first horizontal bristles 321 are oriented toward the second sidewall 230 from the first sidewall 220 parallel to the base 210 while the first tilted bristles 322 are tapered toward the second sidewall 230 And is set in an inclined direction at a predetermined angle at a portion adjacent to the free end. Preferably, the first tapered bristle 322 is inclined obliquely outwardly at an angle of 45 degrees relative to the first sidewall 220.

It is known that the brushing of the dental hygiene can remove the dental floss by a little vibration and pressure through brushing by bringing the bristles at an angle of about 45 degrees to the area of contact between the tooth and the gum. Accordingly, in the present invention, the first inclined bristles 322 inclined at a predetermined angle can penetrate the gingival fissure, which is a gap between the lingual surface of the tooth and the gum, without tilting the toothbrush separately.

The second sidewall 230 includes a second horizontal bristle 331 and a second tilted bristle 332 on the inner side and an array of second horizontal bristles 331 and second tilting bristles 332, The height can be different. The second horizontal bristles 331 are oriented parallel to the base 210 toward the first sidewall 220 at the second sidewall 230 while the second tilted bristles 332 are tapered toward the second sidewall 220 And is set in an inclined direction at a predetermined angle at a portion adjacent to the free end. Preferably, the second beveled bristles 332 are inclined obliquely outwardly at an angle of 45 degrees relative to the second sidewall 230.

In other words, according to the present invention, it is possible to penetrate the gingival fissure, which is a gap between the surface of the tooth and the gingiva, without tilting the toothbrush separately through the second inclined bristles 332 inclined at a predetermined angle.

FIG. 3 illustrates a state of use of a toothbrush for cleaning teeth and gums according to a preferred embodiment of the present invention shown in FIGS. 1 and 2. FIG.

3 (a) is a schematic view illustrating a process of brushing a crown and a gum-cleaning toothbrush according to a preferred embodiment of the present invention on a dentition. As shown in the drawing, the toothbrush for cleaning teeth and gums according to the present invention is configured such that the tooth is received in the space 240 of the head part 200 and does not reciprocate in the transverse direction, which is the toothbrushing direction of the toothbrush according to the prior art, And reciprocates in the forward and backward directions to perform brushing.

Fig. 3 (b) shows a state of brushing the toothbrush in the forward direction according to the preferred embodiment of the present invention.

As the toothbrush of the present invention advances, the first sidewall 220 of the head portion 200 is disposed adjacent to the tooth, specifically, the lingual surface of the tooth. In this process, the vertical bristles 310 are wiped in contact with the occlusal surfaces of the teeth. At the same time, as the first sidewall 220 approaches the dorsal surface of the tooth, a portion of the first horizontal bristles 321 abuts the lingual surface of the tooth to wipe the lapping surface and a portion of the first horizontal bristles 321, So that foreign substances such as plugs caught in the teeth can be cleanly removed.

In addition, the first inclined bristles 322 penetrate the gingival perforations of the dental internal surface, that is, the gaps between the lingual surface of the teeth and the gums, to remove foreign substances such as accumulated tooth surface bacteria and plugs, Brushing can be realized.

3 (c) shows a state of brushing the toothbrush in the backward direction according to the preferred embodiment of the present invention.

With the toothbrush of the present invention moving backward, the second side wall 230 of the head portion 200 is disposed adjacent to the teeth, specifically, the nose of the tooth. In this process, the vertical bristles 310 are wiped in contact with the occlusal surfaces of the teeth. At the same time, as the second sidewall 230 approaches the tooth surface, a portion of the second horizontal bristles 331 abuts the nose of the tooth to clean the nasal surface and the remaining portion of the second horizontal bristles 331, So that foreign substances such as plugs caught in the teeth can be cleanly removed.

In addition, the second inclined bristles 332 penetrate into the gingival fissures outside the teeth, that is, the gaps between the gingival surfaces of the teeth and the gums to remove foreign substances such as accumulated tooth surface bacteria and plugs, and apply a predetermined pressure to the gums Brushing can be realized.

In particular, the handle 100 is coupled to the head portion 200 such that the handle 100 is coupled to the first horizontal bristles 321 and the second horizontal bristles 331 in parallel, The first horizontal bristles 321 and the second horizontal bristles 331 can be inserted and retracted between the teeth according to the forward and backward movement along the axial direction, .

3, the same applies to the molar teeth. However, the same applies to the molar teeth, so that the ball of the face is deformed as much as possible so that the axial direction of the handle becomes perpendicular to the narrow face and the snowy face The first horizontal bristles 321 and the second horizontal bristles 331 can be inserted and retracted between the teeth (between the teeth) in accordance with the forward and backward movement along the axial direction of the handle 100 have.

The toothbrush for cleaning crown and gum according to a preferred embodiment of the present invention can reciprocate in the forward and backward direction as shown in Fig. 3 (a), and can simultaneously clean the tooth surface of the teeth, the lap and the occlusal surface, The same effect as that of the interdental toothbrush can be expected by inserting the bristles. In addition, the present invention can provide an advantage of maintaining the health of the gum by the pressure and vibration of the bristles in the gap between the tooth and the gum.

In addition, the bristles are formed by bundling a plurality of strands or individually on the inner surface of the head portion 200. By sharpening the tips of the strands and the tips of the strands, the cleaning effect can be enhanced. In particular, It is more advantageous when performing the function of the toothbrush. The bristles can be made of nylon elastic material and soft material.

FIGS. 4 through 6 are schematic views of a toothbrush for cleaning teeth and gums according to another embodiment of the present invention. A toothbrush according to another embodiment of the present invention is another variation of the toothbrush shown in Figs. 1 and 2, and a description of similar or identical components will be omitted herein to facilitate a clear understanding of the present invention.

The toothbrush for cleaning crown and gum according to another embodiment of the present invention rotatably connects the head part 200 in the direction of the arrow in FIG. 4 at one end of the grip part 100.

The toothbrush for cleaning crown and gum according to another embodiment of the present invention can be used to simultaneously clean the tooth surface of a tooth and the tongue and the occlusal surface by means of a U-shaped head portion 200 having bristles extending in multiple directions on its inner surface As well as the clearance between the teeth and the teeth and the clearance between the teeth and the gums, it is possible to reliably remove the foreign substances such as plugs by ensuring reliable insertion of the bristles.

The crown and gum cleaning toothbrush can be cleaned by disposing the space 240 of the head part 200 in the tooth arranged at the back of the teeth, i.e., the molar teeth. Since the posterior teeth are disposed adjacent to the inner side of the ball, the toothbrush according to the above-described embodiment may not be aligned with the teeth and may be arranged obliquely to prevent the bristles from effectively penetrating into the gaps between the teeth and the gums .

Accordingly, the toothbrush for cleaning crown and gum according to another embodiment of the present invention is characterized in that the head part 200 is rotatably coupled to the handle part 100.

The grip portion 100 includes a cylindrical portion 170 provided at one end of the grip portion 100, a disc portion 171 attached to an end of the cylindrical portion 170, and a protrusion portion 172).

Correspondingly, the head portion 200 includes a cylindrical receiving groove 270 on the outer surface of the base 210, a stepped portion 271 extending radially around the upper end of the receiving groove 270, And an arc-shaped concave groove (272) is provided in an inner region of the groove (270).

The disc portion 171 of the handle 100 is forcibly inserted into the receiving groove 270 of the head portion 200 so that the disc portion 171 is caught by the step portion 271, (100). The handle portion 100 and the head portion 200 may be made of a soft material to partially or wholly protect the mouth and the gum from being injured in the oral cavity. It can be inserted and fixed in the groove.

As shown in the figure, the cylindrical portion 170 and the circular plate portion 171 of the handle 100 form a circular cross-sectional shape having a different diameter, and correspondingly, the stepped portion 271 of the head portion 200, The groove 270 also has a circular cross-sectional shape. The inner diameter of the stepped portion 271 of the head portion 200 is formed to be larger than the outer diameter of the cylindrical portion 170 of the handle portion 100 and the inner diameter of the receiving groove 270 of the head portion 200 is set to be larger than the outer diameter of the handle portion 100 The outer diameter of the disc portion 171 is larger than the outer diameter of the disc portion 171. Thus, the toothbrush of the present invention can support and hold the head part 200 from the grip part 100 so as to be rotatable.

The disc portion 171 of the handle 100 inserted into the receiving groove 270 of the head unit 200 may be rotated 360 degrees without any limitation. Accordingly, the toothbrush according to another embodiment of the present invention is designed to limit the rotation angle of the head part 200. [

As described above, the disc portion 171 rotatably inserted into the receiving groove 270 has the protruding portion 172 protruding in the vertical direction on one surface of the receiving groove 270 facing the bottom surface, and the protruding portion 172 Is seated on the arc-shaped concave groove 272 of the receiving groove 270. [ That is, the projection 172 is slid along the forming direction of the concave groove 272, and it is possible to limit the turning angle of the head through the arc length of the arc concave groove 272.

The edge of the disc portion 171 and the arc-shaped concave groove are formed to have the same curvature so that the head portion 200 can rotate smoothly with respect to the handle portion 100. [ In other words, the imaginary lines drawn in the circumferential direction at both ends of the disk portion 171 and the concave grooves of the arcuate shape have concentric arrays having the same center and different radii.

In addition, the toothbrush according to another embodiment of the present invention interposes the O-ring 400 between the handle 100 and the head 200. The O-ring 400 is arranged concentrically with the cylindrical portion 170 of the handle 100 and / or the receiving groove 270 of the head portion 200 to block the inflow of water between the handle portion and the head portion It is possible to perform a spacer function to maintain a constant distance between the handle and the cylindrical portion.

The head unit 200 includes a first refraction unit 250 between the base 210 and the first sidewall 220 and a second refraction unit 260 between the base 210 and the second sidewall 230 Can intervene. The first refracting portion 250 provides flexibility to allow the first sidewall 220 extending upward from the front end of the base 210 to flow at a predetermined angle while the second refracting portion 260 provides flexibility to the base The second sidewall 230 extending upward from the rear end side of the first sidewall 210 can be made flexible at a predetermined angle. During the brushing, the first or second sidewalls 220 and 230 are allowed to move in the anteroposterior direction in response to the applied external force or contact with the teeth.
