Abstract

An oral cleaner is provided to remove food dregs and plaque from the teeth and the gum out of reach of a toothbrush effectively without cervical abrasion or damage of the gum by repeating spray and suction of water in turn. The oral cleaner includes a motor(3), a motor shaft(5) formed on the motor, a wheel(1) rotating by being attached to the motor shaft, a spray wrinkled bag(2) for receiving clean water sucked from a main body(4), a suction wrinkled bag(11) for receiving sprayed water containing food dregs, plaque, and bacteria, a steel spring(6) for varying a volume of the wrinkled bags by a tension power, and a brush part(9). The cleaner performs in turn a spray stroke for taking off the dregs and plaque from the teeth by spraying water at a proper pressure, and a suction stroke for discharging the dregs, plaque, and bacteria to the outside by sucking them with the sprayed water.

The present invention relates to an oral scrubber, and more particularly, to rub the brush head on the teeth to remove food waste or plaque by the friction force, unlike the general brushing method, the pressure of the water ejected with the air bubble and sucks it again With suction power, it is a device that applies and develops a method of washing water in the mouth after meals to clean and remove food waste and plaque without any side effects.

In general, brushing with a toothbrush rubs the bristles on the teeth and removes food scraps or plaque by the frictional force. Brushing them with excessive force or by the wrong method causes cervical abrasion or gum damage, which causes the toothbrush to thicken. Narrow dentition, gingival sulcus, deep parts of interdental area, especially fine food residues or plaques in periodontal pockets are almost impossible to remove because bristles cannot reach. Fine food residue or plaque is not removed, causing bad breath and gradually becoming tartar, which leads to gingivitis and periodontitis.

 In addition, there is a device to remove foreign substances such as gingival fissures, interdental and periodontal pockets by spraying water, but this is effective only for the interdental opening and closing because it only sprays water, but the interdental or periodontal pockets that are blocked are deep There are side effects that push foreign matter into place.

In order to solve the above problems, the present invention injects water containing air bubbles at an appropriate pressure to inject the food waste and plaque attached to the teeth and drop the food waste and the plaque and bacteria and sprayed water. By alternately repeating the suction stroke to remove outside the oral cavity, water is vortexed to form swirls and bubbles in the process of alternately spraying and inhaling, so that the toothbrush or tooth that the bristles reach, as well as the general brush It is possible to remove fine food residues and plaques such as interdental, gingival sulcus, and periodontal sac that could not be removed because it could not be reached. It can be removed.

 In addition, the bristle bundle moves freely back and forth according to the flow of water at the inlet of the device where water is injected and sucked, so that the bristle bundle vibrates back and forth as if it is a scaling, and removes foreign substances from the teeth or gums. It is effective because it removes foreign substances from teeth or gums only by a certain force by the injection force and suction force of the water, but it is effective, but there is a characteristic that can prevent tooth wear and gum damage due to the wrong method or excessive force.

Hereinafter, described in detail by the accompanying drawings as follows.

In Figs. 1 and 3, the injection stroke and the suction stroke as shown in Figs. 3A and 3B alternately by rotation of the motor rotating shaft 5 and the wheel 1 attached thereto by the motor 3 in Figs. Is formed.

When the wheel 1 is in the state of FIG. 3B due to the rotation of the wheel 1, the pleat bag for spraying the top plate of the pleat bag in contact with the wheel 1 is pulled by an elastic body such as a steel spring 6 or the like. ) And a suction stroke (B) which enlarges the volume of the suction wrinkle bag 11, and at this time, clean water is sucked from the main body 4 into the injection wrinkle bag 2 by the negative pressure generated in the wrinkle bag. In the suction pleat bag 11, food waste, plaque and bacteria are sucked from the oral cavity together with water sprayed. Subsequently, when the wheel 1 is brought to the state of FIG. Food waste and plaque and bacteria-containing water injected into the inhalation pleat bag 11 are allowed to flow toward the body. At this time, the role of the four backflow prevention ball (7) at the front, rear inlet of each pleated bag so that the contents entered into the pleated bag does not become a reverse flow. As such, when the injection stroke and the suction stroke are alternately repeated, foreign substances in deep areas such as gingiva, interdental and periodontal sac, which the brush head cannot reach, can be removed as if water is washed in the mouth and washed out of the mouth.

In addition, the bristle bundle 9 is pushed forward by surpassing the tensile force of the soft plastic spring 10 by the pressure of the water sprayed when the clean water entering the pleating bag 2 for spraying is injected toward the inlet of the apparatus. When the water is sucked into the inhalation pleat bag 11 during the inhalation stroke, the bristle bundles 9 retreat backward as the water flows. When the injection stroke and the suction stroke are alternately repeated, as if the bird pecked with beak, the bristle bundle (9) vibrates back and forth and effectively removes foreign substances from the teeth or gums without side effects.

The soft silicone or rubber cup 8 at the forefront of the device serves to bring the oral irrigator into close contact with the teeth or gums, maximizing the effect during the spraying or inhalation stroke and also acting as a massage to the gums.

As described above, the present invention, the injection stroke to drop the food waste and plaque attached to the teeth by spraying the water containing the air bubbles at a suitable pressure, and thus the water sprayed to the dropped food waste and plaque and bacteria in the oral cavity And a device that alternately repeats the suction stroke to inhale and remove it out of the oral cavity, and a brush bristle that moves freely back and forth according to the flow of water at the inlet of the device where water is injected and sucked, as if a bird is pecking at its beak, In addition, the toothbrush can be wiped with a constant force to effectively manage food residues and plaque in deep areas such as interdental, gingival and periodontal pockets that can not be removed by normal brushing without side effects such as cervical abrasion and gum damage. .

In particular, if gum disease progresses more than moderately, the periodontal sac management should be continued even after the gum treatment in the hospital, but the gum disease will not progress anymore, but there is no mechanism to manage the periodontal sac on the market. In many cases, the tooth eventually lost, but the present invention allows anyone to easily manage the periodontal pocket without any special technique.
