Description

  The present invention relates to a cleaning device, and relates to a cleaning device for cleaning the oral cavity.

  A toothbrush is generally used to clean the oral cavity. In recent years, electric toothbrushes have come out as toothbrushes, and technical improvements are progressing. In addition, there is a liquid thing called mouthwash that performs oral care. Furthermore, in recent years, in addition to dental floss and interdental brushes for cleaning between teeth, what is called air floss has come out. The air floss is shaped like an electric toothbrush as a whole, and there is a nozzle with a small hole at the tip of the handle instead of the brush. How to use is to remove the plaque by putting a small hole in the nozzle between the teeth and switching it on so that water and air come out vigorously.

  In addition to the above, an apparatus for cleaning the oral cavity using microbubbles has been proposed as described in Patent Document 1. The microbubbles are ejected from the toothbrush portion at the tip, and the oral cavity inner wall and the tooth surface are cleaned. Regarding the use of nanobubbles, some are disclosed as described in Patent Document 2. In Patent Document 2, Patent Document 3 is also cited as a prior art. Here, in general, a microbubble refers to a bubble with a sphere equivalent diameter of 1 to 100 micrometers, a nanobubble is a nano-level bubble, also referred to as an ultrafine bubble, and a sphere equivalent diameter of 1 micrometer or less. Fine bubbles refer to bubbles having a sphere equivalent diameter of 100 micrometers or less, and include the above-described microbubbles and ultrafine bubbles.

  However, in the prior art, if it is not electric, it is necessary to actually move a hand about a toothbrush. Even if it is electric, there is a problem that toothpaste is required. In other words, when using a toothbrush, it is necessary to brush and comb the teeth. Moreover, since removal of dirt between teeth is not sufficient with a toothbrush, separate tools such as an interdental brush, dental floss, and air floss are required.

  Moreover, although the case where a micro bubble and a nano bubble are used has also been proposed, as described in Patent Documents 1, 2, and 3, it is assumed that the tip takes the shape of a toothbrush or an air floss nozzle. Even if the cleaning effect is improved, it is only an extension of the toothbrush or air floss, and it is merely a matter of brushing teeth one by one and cleaning between the teeth one by one.

  Therefore, the present invention can integrate the polishing process and the rowing process when cleaning the oral cavity using a liquid in which a plurality of bubbles such as fine bubbles are generated. It is an object of the present invention to provide a cleaning device that can perform cleaning of the oral cavity and cleaning of the tooth surface all together.

  A first aspect of the present invention is a cleaning device for cleaning the inside of an oral cavity, wherein a generating means for generating a plurality of bubbles in a liquid, a sending means for sending out a liquid having the plurality of bubbles, and a mouth of the mouth A plurality of spouts that are accommodated in the device and that are connected to the delivery means and cause the fluid having a plurality of bubbles sent out to pass through a passage formed by a hollow inside to be ejected in the oral cavity. The appliance has a dentition-shaped portion along the dentition between the upper teeth and the lower teeth, and the plurality of jets of the upper teeth and lower teeth It is formed in the said dentition shape part along at least one dentition of a dentition.

  According to a second aspect of the present invention, in the first aspect, the delivery means delivers the liquid having the plurality of bubbles at a periodic rhythm.

  According to a third aspect of the present invention, in the first or second aspect, the delivery means includes an adjustment means for adjusting a force for delivering the liquid having the plurality of bubbles.

  According to the present invention, the cleaning implement that is placed in the mouth and accommodated in the oral cavity has a dentition-shaped portion along the dentition between the upper jaw teeth and the lower jaw teeth, and includes a plurality of bubbles (fine bubbles). A plurality of spouts that pass through the passage formed by the hollow inside and are ejected in the oral cavity in at least one of the dentition of the upper teeth and the dentition of the lower teeth Since it is formed along the dentition shape portion, cleaning of the oral cavity and cleaning of the tooth surface can be performed simultaneously. In addition, if the fine bubble is used, the cleaning power is strong, toothpaste and the like are unnecessary, and rowing can be performed simultaneously with cleaning with water or hot water. In particular, if the fine bubble in which carbon dioxide gas is dissolved, the effect is significant. Moreover, as a washing | cleaning apparatus, according to the shape of the washing | cleaning instrument, while being able to fill a liquid easily, the inner wall in an oral cavity can be massaged by controlling it, using the flow by a liquid.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited thereto.

  FIG. 1 is a block diagram showing an entire cleaning apparatus according to an embodiment of the present invention.

  The cleaning apparatus 1 includes a hot water tank 3, a water pump 5 (an example of a delivery unit) connected to the hot water tank 3 via a connection pipe 4, and a fine bubble generator 7 connected to the water pump 5 via a connection pipe 6. (An example of generating means), a cleaning instrument 9 connected to the fine bubble generating unit 7 via a connecting pipe 8, and a water pressure adjusting valve 10 provided between the fine bubble generating unit 7 and the cleaning instrument 9. Further, the cleaning apparatus 1 includes a carbon dioxide gas cylinder 11 having carbon dioxide gas as a gas used for generating fine bubbles, a pressure reducing valve 13 connected to the carbon dioxide gas cylinder 11, and a fragrance cartridge connected to the fine bubble generating unit 7. 15 and an electromagnetic valve 17 provided between the pressure reducing valve 13 and the fragrance cartridge 15. The water pump 5 and the electromagnetic valve 17 are electrically connected to a switch 21 connected to an AC-DC converter 19, and the operation is turned on / off by the switch 21. The power supply to the water pump 5 and the electromagnetic valve 17 when the switch 21 is turned on is performed by DC conversion from the household outlet (100 V) by the AC-DC converter 19.

  2 is a view showing the cleaning tool of FIG. 1, FIG. 2 (A) is a plan view, FIG. 2 (B) is a front view, and FIG. 2 (C) is a left side view. FIG. 3 is a diagram illustrating a state in which the cleaning tool of FIG. 1 is actually used. Hereinafter, the cleaning tool will be specifically described with reference to FIGS. 2 and 3.

  The cleaning instrument 9 has a flat U-shape as a whole. The thickness is about 5 mm to prevent aspiration. This U-shape is formed by the dentition-shaped portion 9a along the dentition between the upper teeth and the lower teeth. The cleaning instrument 9 is provided with a water inlet 9 b connected to the connection pipe 8. Moreover, the dentition shape part 9a is provided with jet nozzles 9c arranged in two rows along the dentition of the upper teeth on the upper surface. Here, the diameter of the jet port 9c is very small and sufficient. Similarly, in the dentition shape portion 9a, jet ports arranged in two rows along the dentition of the lower jaw teeth are also provided on the lower surface. The reason why they are arranged in two rows is that they can be delivered to the tooth surface or alveolar portion as much as possible by arranging them on the front and back sides of the teeth. The dentition-shaped portion 9a is formed with a passage through which a hollow liquid passes through the water inlet 9b as an inlet, and the passage and the jet port 9c are connected to each other. Further, in the dentition-shaped portion 9a, two guide paths 9d having a concave shape are formed near the lips on the water inlet 9b side. As shown in FIG. 3, the guide path 9d is formed from the mouth 9c of the cleaning device 9 housed in the oral cavity, and the mouth and the liquid for cleaning the oral cavity, such as hot water, fill the mouth and exit from the lips. It plays a role of guiding when discharged into the water. The material of the cleaning device 9 is made of nylon, resin, or the like that does not crush the hollow inside even if a user bites it, while a general mouth guard uses rubber to protect teeth. The reason for this strength is that it is necessary to secure a passage by the hollow inside even if the user bites.

  Next, operations of the cleaning device 1 and the cleaning tool 9 will be described with reference to FIGS. 1 to 3.

  First, the hot water in the hot water tank 3 is an example of a liquid, but is sent to the fine bubble generating unit 7 by the water pump 5 that is powered on by the switch 21. The fine bubble generating unit 7 generates fine bubbles using a gas. As a specific technique, for example, the technique disclosed in JP 2010-167404 A or JP 2012-75744 A may be used. . Here, in generating fine bubbles, as described below, the use of carbon dioxide gas to dissolve it is one of the major features.

  The carbon dioxide gas in the carbon dioxide cylinder 11 is depressurized by the pressure reducing valve 13. When the electromagnetic valve 17 is turned off by the switch 21, the carbon dioxide gas is blocked by the electromagnetic valve. This prevents the carbon dioxide from flowing out when the apparatus that is not cleaned by the user is unused. When the electromagnetic valve 17 is turned on by the switch 21, the carbon dioxide gas is scented by passing through the fragrance cartridge 15. The scented carbon dioxide gas is used for generating fine bubbles in the fine bubble generating unit 7 and is dissolved in warm water. The hot water in which the carbon dioxide gas is dissolved is adjusted in water pressure by the water pressure adjusting valve 10 and is sent to the cleaning device 9, and is ejected vigorously on the tooth surface from the plurality of jet nozzles 9c with respect to the upper dentition and the lower dentition. Is done.

  In this way, the plurality of spouts 9c are arranged along the dentition, and hot water containing carbon dioxide fine bubbles is ejected from the immediate vicinity of the teeth (tooth and alveolar portion), and the interdental and periodontal pockets are fine. Fine bubbles enter into a large space, and thus it is possible to clean a portion that was difficult with the conventional method. Further, the amount of unpolished material is reduced as compared with the conventional case, and the surface of the tooth and the gingiva are removed cleanly. This makes it possible to prevent tooth decay and periodontal disease. Here, the reason why the contamination by the carbon dioxide fine bubble can be removed is not only due to the water pressure but also due to being charged. That is, fine bubbles are negatively charged, and there is a surface that can adsorb positively charged dirt. In addition, the cleaning device of this time is not for each one such as air floss, but by putting the cleaning tool 9 in the mouth and turning on the power, the upper teeth and lower jaws The water flow toward the teeth is jetted at an appropriate water pressure, and warm water containing carbon dioxide fine bubbles is jetted out to fill the mouth, cleaning the entire oral cavity as well as the tooth surface. Being able to do so is also an important merit. In addition, there is an advantage that rinsing is unnecessary because a toothpaste is not necessary when using a toothbrush, and even if it has carbon dioxide gas or scent, it is basically washed with warm water. As a result, it is possible to reduce the time and effort of washing and rinsing. In addition, since carbon dioxide gas is scented and warm water containing scented carbon dioxide fine bubbles, it is also devised that measures against bad breath are also taken.

  In addition, there is a massage effect by warm water containing carbon dioxide fine bubbles injected into the gums at an appropriate water pressure by the water flow, but the water flow spreads throughout the mouth, so that the mouth massage effect by the water flow can also be obtained However, it is a big difference from conventional toothbrushes, air floss, etc., and can be said to be a characteristic effect. It should be noted that the water pressure can be adjusted to a water pressure appropriate for each user by adjusting the water pressure adjusting valve 10 at the request of the user. As a further contrivance from this point, for example, when warm water is sent out by a water pump at a periodic rhythm, the massage effect can be increased. In addition, as described above, with the new style that can be completed in a short time of washing with the mouth full, induction is a device that makes it easy to discharge hot water used for washing from the oral cavity to the outside through the lips. It is also characterized by providing a path 9d.

  In addition, it describes further below that there exists an effect by using a carbon dioxide gas by using such a carbon dioxide fine bubble. When carbon dioxide gas is used, there are effects such as an increase in the cleaning effect, an increase in the antibacterial effect, and an improvement in blood flow by peripheral blood vessel dilation. Furthermore, as an apparatus, it is important to prevent bacteria from growing in the remaining hot water, but by using carbon dioxide gas, oxygen in the water can be driven out and bacterial growth can be suppressed. There is also an effect. This also has the advantage that the warm water used for cleaning can be kept clean and the oral cavity can be cleaned cleanly.

  In the above description, it is described that an adult or the like uses the cleaning device 1 in a general household. However, the effect is effective for a person who is difficult to brush his / her teeth such as an infant or an elderly person. Is big. In particular, elderly people often suffer from periodontal disease due to their teeth, and brushing with a toothbrush may be painful. In addition, there is a massage effect, and the merit of using the cleaning device 1 is great. This can be said to be very beneficial not only at home but also in nursing and nursing settings. Furthermore, not only elderly people but also people who have a tooth defect can be easily cleaned.

It is line sectional drawing. Note that the left side view shown in FIG. 9 is the same as the right side view omitted in the drawing. FIG. 11 is a schematic diagram showing a state in which the cleaning device is sandwiched between the upper and lower teeth at the position XI in FIG. 9, and FIG. 12 is the upper teeth at the position XII in FIG. It is the schematic model which showed the state by which the washing | cleaning implement was pinched | interposed between the teeth of the lower jaw.

  Hereinafter, differences from those shown in FIGS. 1 and 2 will be mainly described. Similarly to the cleaning instrument 9, the cleaning instrument 25 is provided with a dentition-shaped portion 25a, a water inlet 9b, and a jet outlet 25d. In addition, the cleaning device 25 is also provided with a recess 25e along the dentition that houses the tip of the dentition of the upper jaw teeth. The recess 25e enables positioning of the teeth and the ejection port 25d and fixation during cleaning (see FIGS. 11 and 12). In addition, as shown in FIG. 9, the cleaning device 9 has a thin throat side thickness when the throat side thickness is compared with the lip side thickness. By adopting this shape, in the state where the dentition-shaped portion 25a is bitten by the teeth while being stored in the mouth, the teeth between the upper teeth and the lower teeth are firmly placed in the oral cavity in relation to the jaw structure. The row-shaped portion 25a is to be accommodated. In addition, in FIG. 10-12, the channel | path 25f by the hollow inside is also shown.

  Here, description is added about the injection port 25c. In the cleaning device 9, the injection ports are arranged in two rows along the dentition, and the opening direction is upward, which is the upper tooth side, and the lower one is the lower tooth side. It turned down. However, in this cleaning instrument 25, although the injection ports 25c are also arranged in two rows, the opening direction is toward the center of the teeth, and the upper direction is directed upward, which is the upper teeth 26a and 26c side. While facing the tooth surface of the tooth at an acute angle as much as possible, the lower one is facing downward on the lower teeth 26b and 26d side, while intersecting the tooth surface of the tooth at an acute angle as much as possible (See FIGS. 11 and 12). By doing in this way, as shown in FIG.11 and FIG.12, the high washing | cleaning effect by the hot water 28 containing a carbon dioxide fine bubble will be acquired.
