Description

Two way toothbrush with improved movement pattern {TOOTHBRUSH}

The present invention relates to a toothbrush capable of brushing a simple, easy and repeating operation pattern compared to various brushing operations required when brushing with a known toothbrush.

Brush heads are provided on both sides of the head so that brushing of the upper and lower teeth is performed on the buccal sac when brushing the outer teeth, and brushing on the palate when brushing to remove the tongue (or tongue) of the tongue. The present invention relates to a bidirectional toothbrush having improved operation patterns that can expect two or more effects with one operation pattern.

In the technique about the toothbrush,

Korean Utility Model Publication No. 20-1999-0020605 (published on June 15, 1999, hereinafter referred to as 'prior art 1') `` Toothbrush with improved brushing function '' is proposed,

The prior art 1 is the head and the handle is maintained at an obtuse angle of the 'b' shape by integrating the head and the handle is formed on one side of the head and the bent downwardly fixed to the plurality of teeth in front of the head, the handle portion Protruding part for thumb support is formed at the proper position on the outer circumference, so as to promote correct brushing habit in the vertical direction, while minimizing the radius of arm movement according to the brushing of vertical movement, significantly reducing fatigue, especially the efficiency of brushing (e.g., It is a technology related to toothbrushes that can improve plaque removal).

As another technology, Korea Utility Model Registration No. 20-0225409 (registered on March 16, 2001, hereinafter referred to as `` advanced technology 2 '') `` Chisol '' is proposed.

The prior art 2 is the bristles are implanted in the head member of the tip of the toothbrush, the handle portion and the neck portion in the longitudinal direction is formed integrally with the head member is configured to be able to clean the teeth by holding the handle by hand In the above, the head member is formed to cross the longitudinal direction of the toothbrush rod, thereby increasing the cleaning effect of the food residue and plaque remaining between the teeth by maximizing the effective contact area between the teeth and the bristles,

In addition, when cleaning the molar teeth located inside the oral cavity, it is easy to move to the location and wash them.In case of washing the tongue, incisor, and incisor teeth, the angles of the fingers, wrists, and arms held by the toothbrush are placed in a straight line. It is a very useful toothbrush technology that can be easily cleaned even when the elderly and children, such as the tooth cleaning by inducing posture that does not overdo the arm.

The prior art 1 has a configuration in which the head is integrated into a 'b' shape on one side of the handle for brushing up and down,

According to the direction in which the head is bent, i.e. bent in the left direction and provided with the bristles in front of it, the handle is below and the head is above when brushing to the outside of the tooth located on the left of the upper and lower teeth. You can brush while you are

When brushing the tooth on the right side of the upper teeth, brushing is not possible with the handle under and the head above. On the contrary, the handle with the handle over and under the head, ie upside down, should be brushed.

In this case, the head does not touch the upper left inner side of the upper teeth and the lower right inner side when the head is held downward or upward when brushing the inner side of the upper teeth and the inner side of the lower teeth. If you can not brush or brush the mouth by pushing the tail of the mouth to the molar side as much as possible, there is a limit to the brush head to reach the molar teeth located at the end.

The prior art 2 is a configuration in which the head member is integrally formed in the neck portion of the handle part to form an approximately 'T' shape for brushing up and down like the prior art 1,

Compared to the prior art 1, the brushing operation on the inner side of the tooth located on the left side of the upper teeth, the inner side of the tooth located on the right side of the lower teeth can be made smoothly,

Looking at the brushing operation for brushing the teeth using the toothbrush of the prior art 2,

A first brushing action on the outer sides of the intermeshed upper and lower teeth,

A second brushing action against the medial portion of the upper teeth while holding the bristles in the first brushing action facing opposite,

A third brushing action with the bristle side facing up and the upper teeth molar engaging portion (i.e. the intermeshing area with the lower teeth, hereinafter referred to as the 'head'),

A fourth brushing action for the lower molar engagement, with the bristle side facing down,

A fifth brushing action on the inside of the lower teeth, with the bristle side facing outward,

A sixth brushing action on the tongue, holding the bristle side down;

A seventh brushing action on the palate, with the bristle side facing up,

Eighth and ninth brushing movements of the left and right part of the buccal sac, with the bristle side facing outwards and in the inner part of the cheek in the mouth (hereinafter referred to as the 'scapula'),

It can be done as

The various movements of such brushing are a factor that increases the fatigue of the arm, like a known toothbrush, in which a head is formed in the same direction according to the length of the handle and bristles are provided on one side of the head, and especially used by children who are inexperienced in brushing. Not only is it difficult to do this, but it also acts as a deterrent to having the right brushing habits.

In addition, the prior art 1 and 2 may exhibit a certain degree of performance in the tooth cleaning, 'b'-shaped toothbrushes,' T'-shaped toothbrushes, both the bristles and teeth to correspond to the teeth of the teeth when the teeth contact each other. In addition, the bristles of the bristles can cover each tooth in line with the teeth, that is, the structure is not in close contact with each other, deteriorating the removal of foreign matter and plaque in the interdental,

There is an inconvenience of using an inter-dental brush or a dental floss as a separate removal tool.

In order to solve the above problems, the bidirectional toothbrush with improved operation pattern according to the present invention,

Grip portions;

A head portion provided at an end of the grip portion and having a shape orthogonal to the longitudinal direction of the grip portion; And

Bristles provided on the front and rear surfaces of the head portion, respectively;

It is made, including.

Here, the head portion is made of two powders,

The respective powders are connected to each other at opposite ends of the grip portion by an elastic relay member,

The brush head and the teeth in contact with each other by the pressing force in the state of brushing up and down when the movement of the respective powders are pushed back to the dents relative to the relay member, characterized in that the operation to return to the original position.

In addition, the powder and the powder of the head portion is characterized by forming obtuse angle (鈍角) with respect to the relay member when viewed from the plane.

* And the bristles located in front of the obtuse side in the two powder is formed in a concave curved shape when the contact with the teeth when viewed in a plane,

In the two powders, the bristles located on the rear side opposite to the obtuse angle are characterized in that the contact portion with the teeth is convexly curved when viewed in plan view.

Bi-directional toothbrush with improved operation pattern according to the present invention,

The two parts of the head are arranged opposite to each other on the upper part of the grip to form a shape in which the grip part and the two powders are orthogonal to each other. By increasing the adhesion to the teeth in the contact area, there is an excellent effect in the teeth cleaning, interdental foreign matter and plaque removal.

In addition, by providing the bristles on the front and rear, ie both sides of the two powders, there is an effect that can be brushed at the same time by a single brushing operation pattern on the molar outer part and scapula, tongue and palate and head.

In addition, it is possible to brush teeth, tongue, palate, buccal sac and cusp only by the pattern of up and down reciprocating brushing, and back and forth or right and left reciprocating movement (for example, reciprocating back and forth or left and right depending on user's preference when brushing head). have.

In addition, children who are inexperienced in brushing are comfortable to use and have the proper brushing habits.

In addition, the interdental and plaque removal performance is excellent, there is an effect that does not require a separate removal tool (interdental toothbrush or dental floss).

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

Prior to the description, the head side is set as the upper side or the upper side based on FIG. 1, the grip side is set as the lower side or the lower side, and the bristle side forming the obtuse angle is set as the front side or the front side, and the right angle is defined. The bristle side which comprises is defined as a back part or a back part.

As shown in Figures 1 to 4, the bidirectional toothbrush with improved operation pattern according to the present invention,

It consists of a grip part 10, a head part 20, and bristles 30.

Looking at each configuration,

The grip part 10

As shown in Figs. 1 to 3,

Neck (11),

A grip body 12 connected to the neck 11 and having a proper length to be easily grasped by one hand; and

Holding part 13 provided on the grip body 11

It is made, including.

At this time, the neck 11 preferably has a smaller diameter than the grip body (11).

And the gripping portion 13 is preferably made of an elastomer (elastomer) material to prevent slipping,

In addition, the gripping portion 13 preferably has a shape corresponding to the finger of the hand held in order to improve the grip force.

Head 20

As shown in Figures 1 to 3,

* It is provided in the edge part of the said grip part 10, and has a shape orthogonal to the longitudinal direction of the said grip part 10,

The grip part 10 and the head part 20 which are interconnected form a 'T' shape when viewed from the front.

At this time, the head portion 20 may be formed of one body,

When the bristle 30 and the tooth 1 are in contact with each other by the pressing force, the head portion 20 should be able to cope with the dentition.

To this end, in the present invention

The head portion 20 is made of two powders (20A, 20B),

By connecting each of the powders 20A, 20B to the end of the grip part 10, that is, the end of the grip part 10, the neck part 11 by an elastic relay member 25,

During the vertical brushing movement, the powders 20A and 20B are pushed back to their teeth based on the relay member 25, and the operation of repeating the original position is repeated.

More specifically, the incisors, fangs, and molars that form the upper and lower teeth are different in shape, and the incisors and fangs are slenderer toward the bottom, and the molars are blunt, and the outer surfaces of the incisors, fangs, and molars are especially It can be seen that it is not constant.

The two powders 20A and 20B are oscillated when the brush head 30 and the tooth 1 are in contact with each other when the upper and lower teeth are brushed based on the relay member 25 according to the shape of the tooth 1. By repeating the exercise, it exhibits an even greater effect on tooth cleaning or debris and plaque removal compared to known toothbrushes with a fixed head.

In addition, the lengths of the two powders 20A and 20B constituting the head part 20 may be formed to have an appropriate length for infants, children, and adults. In this case, the "suitable length" means that the length of the powder bristles 30 can be contacted to the ends of the molar teeth without causing pain when the grip part 10 presses the mouth tail. .

And the relay member 25 may be implemented in various ways,

Referring to Figure 2 the relay member 25 of the example,

As the grip part 10 and the head part 20 are integrally formed, the grip part 10 and the head part 20 are made to have elastic force while being the self-connecting part 251 of the grip part 10 and the head part 20.

Another example of the relay member 25, referring to Figure 3,

It is composed of a separate coupling portion 252 having an elastic force, and the coupling portion 252 is interposed between the neck portion 11 and the head portion 20 of the grip portion 10. As a result, the head part 20 is connected to the neck part 11 and the head part 20 of the grip part 10 by fixing means, so that the head part 20 is connected to the neck part 11 of the grip part 10.

Brush head 30

As shown in Figures 1 to 4,

To be provided on the front and rear of the two powder (20A, 20B) of the head portion 20,

When brushing teeth, a plurality of soft brushes are formed in a dense form to remove foreign substances and plaques between the interdental teeth, plaque, tongue tongue tongue (or white feces), and foreign bodies of the buccal sac.

In this case, the plurality of soft brushes are densely formed in a form corresponding to the front and rear circumferences in the front and rear shapes of the head part 20.

The bristle 30 of the powder 20A on one side and the bristle 30 of the powder 20B on the other side may be interconnected or non-connected (spaced).

On the other hand, in the toothbrush according to the invention as shown in FIG.

The powder 20A and the powder 20B of the head 20 preferably form obtuse angles with respect to the relay member 25 when viewed from a plane.

This is to have a structure that can be in close contact with the upper bristle and the lower teeth 30 located on the obtuse side,

In addition, the bristles (3) located on the opposite side of the obtuse angle, that is, the right angle (優 角) is to have a structure that can be in close contact with the upper teeth and the lower teeth inner portion.

Hereinafter, in order to distinguish and describe the bristles 30 located on the obtuse side and the bristles 30 located on the right side, the former bristles are collectively referred to as 'obtended bristles', and the reference numeral is set as '30A'.

In addition, the latter bristles are collectively referred to as 'right bristle bristles' and the reference numerals for them are designated as '30B'.

On the other hand, in the toothbrush according to the invention as shown in FIG.

In the two powders 20A and 20B, the obtuse bristle bristles 30A are formed in a concave curved shape when the contact portion 31 with the tooth 1 is viewed in plan view.

In addition, the right bristle bristles 30B in the two powders 20A and 20B are preferably formed in a convexly curved form in contact with the tooth 1 when viewed from a plane.

This is because the teeth of the upper teeth and the lower teeth are arranged in a streamlined fashion rather than a straight line.

Eventually, the brushing is made in a form of wrapping the outer or inner portion of the tooth through the curved shape of the obtuse bristle bristles 30A and the right angle bristle bristles 30B, thereby facilitating brushing to remove foreign substances or plaque between the interdental teeth.

Referring to Figures 5 to 10 with respect to the effect of the toothbrush according to the invention made of the above configuration,

Upper and lower reciprocating first brushing operation (A1) with respect to the outer side of the upper and lower teeth while holding the grip portion 10 such that the obtuse bristle bristles 30A can contact the outer side of the upper and lower teeth contacted with each other,

At this time, the first brushing operation (A1) while moving to the left and right to brush the teeth on the outer side of the front teeth, canines, molars, and also brushing the buccal bag through the right angle brush head (30B) when brushing the outer portion of the molars Together.

Vertically reciprocating second brushing operation A2 of the upper teeth, while holding the grip portion 10 so that the right bristle bristles 30B can contact the inner teeth of the open mouth,

Front and rear reciprocation of each engaging portion of the upper and lower teeth with the grip 10 being held so that the right bristle bristle 30B and the obtuse bristle 30A (or vice versa) contact the upper and lower teeth of the open mouth. Third brushing operation (A3),

At this time, the brushing of the upper teeth and the lower teeth at the time of the third brushing operation (A3) is made at the same time.

Up and down reciprocating fourth brushing operation (A4) with respect to the inner teeth of the lower teeth while holding the grip portion 10 so that the right bristle bristles 30B can contact the inner teeth of the lower teeth of the open mouth,

At this time, brushing about the circumference of the tongue is also performed through the obtuse bristle brush 30A during the fourth brushing operation A4.

The back and forth reciprocating fifth brushing motion of the tongue and the palate with the grip part 10 held so that the obtuse bristle 30A on the tongue of the open mouth and the right bristle 30B on the palate, or vice versa. A5),

At this time, it is preferable that each of the obtuse bristle 30A and the right angle bristle 30B are open to the upper portion of the tongue and the palate.

The first to fifth brushing operations A1 to A5 are not limited thereto.

As in the above first to fifth brushing operations (A1 to A5), the brushing operation using the toothbrush according to the present invention is simple and constant as a whole, so that anyone can easily use, in particular so that children who are inexperienced in brushing have a correct brushing habit. Can be induced.
