Description

[0001] WATER IRRIGATOR WITH STERILIZING EFFECT [0002]

More particularly, the present invention relates to a mouth washer having sterilizing effect, and more particularly, to a mouth washer which has a sterilizing effect, and more particularly, To the pump and the water electrolytic cell to rapidly supply a sufficient amount of water in proportion to the amount of water to be fed and to transfer the water in the water tank through the electrolytic water in the water tank, The inside of the washer can be sterilized at the same time.

Generally, a water irrigator is widely used for personal hygiene in a dental treatment field or a home. Particularly, it is mainly used by patients who have undergone dental procedures such as orthodontic treatment or prosthodontics, those who can not use toothbrushes, and people with bad breath due to food residues. Recently, however, these mouthwashers have been widely used as an auxiliary jig cleaning tool as well as a massage effect using personal hygiene and water pressure of a washing machine rather than a therapeutic purpose.

Such an oral irrigator is also called a water irrigating device and is used to clean the oral cavity using a suitable water pressure. The irrigation device includes a system for injecting water at a constant pressure, a system for controlling pulsation and water pressure, Various oral mouth washers have been developed as in Patent Documents 1 to 3, such as an injection pump system.

The patent document 1 relates to a water purifier that combines a water purifier for producing drinking water and a mouthwasher which is capable of washing even food wastes sandwiched between teeth and a water purifier combined with a water purifier. Conventional water purifier was not equipped with a mouth washer. In the conventional mouth washer, there was a water purifier for simple water purifier. However, since there was not a water purifier having sufficient water purifying ability enough to be able to drink, Of water purifier and mouthwasher are combined into a single product.

Patent Document 2 discloses a conventional oral washing machine valve that controls the amount of oral wash water flowing in the mouth washer and controls the flow of oral wash water when not in use, The water flow control unit and the spray nozzle for spraying the thin and strong water stream are performed so as to prevent the splashing of the spray nozzle by the water pressure during use of the mouth washer and to prevent leakage phenomenon by installing double sealing member for preventing water leakage The present invention relates to a mouth washer.

Patent Document 3 relates to an oral cleanser which is connected to a directional valve of a water supply valve to which mixed water of cold water, hot water or cold or hot water is supplied to wash and massage teeth and gums with water supplied, The present invention relates to an oral care device which allows a button to be sprayed or stopped by a nozzle to be conveniently operated using a small force while maintaining uniform spray pressure of sprayed washing water.

Among the conventional oral cleaners, a method of storing water required for cleaning in a water tank includes the water tank 30 as shown in FIG. That is, the conventional oral cleaner includes a main body 10, a pump 20 installed in the main body 10, a water tank 30 which can store predetermined water and is mounted on the main body 10, And an ejection portion 40 for ejecting water into the oral cavity as the water is fed through the pump 20. The main body 10 is provided with a control means 11 such as a button for controlling the pump 20 or the like.

However, these conventional oral cleaners (washing machines) have the following problems.

(1) Since the conventional oral cleaning device cleans the inside of the oral cavity by sending water by a pump, the cleaning effect is obtained only by the pressure of the water to be fed.

(2) Therefore, in order to enhance the cleaning effect, additives such as salt are added to the water tank to improve the cleaning effect together with the water pressure. Therefore, it is troublesome to prepare or purchase additives separately and to introduce them into a water tank.

(3) In the case of an additive which causes rust in metal like salt, if such additive is added to a conventional oral cleanser for a long time, the composition of the conventional oral cleanser may be hardened or clogged due to the influence of salt, There is a concern.

(4) On the other hand, although the cleaning effect can be improved according to the additive added to the conventional mouthwasher, there is almost no additive to increase the effect on sterilization.

(5) In particular, if the water containing the water tank is not used for a long time, bacteria may multiply therein. If the mouth is washed with the water in which the bacteria are grown, there is a high possibility of bacterial infection.

Korean Patent Publication No. 10-2006-0056919 (published on May 25, 2006) Korean Patent Laid-Open No. 10-2010-0028231 (Disclosure Date: March 12, 2010) Korean Registration Practical Work No. 0451850 (Registration date: 2011.01.07)

The present invention takes this point into consideration. When the water electrolytic cell is installed in a water tank and the water is instantaneously electrolytically electrolyzed in the electrolytic water bath, the water can be cleaned by minimizing the evaporation (loss) of hydrogen in the air It is possible to obtain a sterilizing effect through the sterilizing action of hydrogen water without using any additive, and furthermore, sterilization effect which makes it possible to use safely and conveniently since no additive such as salt is used, The present invention has been made in view of the above problems.

In addition, since the present invention controls the intensity of the power applied to the pump and the electrolytic cell in proportion to the flow rate to be jetted through the flow rate regulator, even if a large amount of water flows out at one time, a stronger power is supplied to the electrolytic cell The present invention provides a mouth washer having a sterilizing effect that can sufficiently supply a desired amount of hydrogen by increasing the water electrolysis amount.

To achieve the above object, the present invention provides a sterilizing mouthwasher comprising: a body; A water tank 100 capable of storing a predetermined amount of water inside the main body B; A water electrolytic bath 200 mounted in the water tank 100 to electrolyze water to generate hydrogen water; A pipe (300) having one side connected to the water electrolytic bath (200) and the other side projecting out of the main body (B); A handpiece 310 for actuating a proximity switch 311 mounted on the main body B as it is mounted on the main body B is connected to the other end of the pipeline 300 to spray hot water through the nozzle, ); A flow rate controller 320 installed at least one of the main body B and the handpiece 310 for controlling the flow rate of hydrogen gas discharged through the handpiece 310; A pump 400 mounted in the main body B and supplying hydrogenated water through the piping 300; A power supply 500 mounted on the main body B for supplying a power supplied from the outside to the hydrogen-based electrolytic bath 200 and the pump 400 or a battery installed in the electrolytic bath 200; And a controller 600 mounted on the main body B to control the pump 400 and the power supply 500. The proximity switch 311 is connected to the handpiece 310 in the main body B, The controller 600 outputs an operation signal to the controller 600 so as to allow the flow rate set by the flow rate controller 320 to flow out of the flow rate controller 320, And the power of the power source is applied to the pump 400 and the water electrolyzer 200, respectively.

In particular, the hydrogen-containing electrolytic bath 200 is installed on the bottom surface of the water tub 100, and water is introduced into the water bath 100 at a predetermined height H, Water can be prevented from flowing into the water electrolytic bath 200.

In addition, the flow rate controller 320 is configured to control the flow rate in a large, medium, and small three-stage.

The proximity switch 311 may be configured such that when the magnet mounted on the handpiece 310 and the handpiece 310 mounted on the main body B are stuck or fitted on the main body B, And a Hall sensor for detecting a magnetic field of the Hall element.

The oral cleanser having a germicidal effect according to the present invention has the following effects.

(1) Since the inside of the oral cavity is washed with hydrogen water generated by electrolysis in a hydrogen water electrolytic cell, a sterilizing effect can be obtained by sterilizing the hydrogen water.

(2) In particular, since the sterilizing action can be obtained as in the present invention by adding a water electrolytic bath to the conventional oral cleanser, the sterilizing effect of the entire water pipe in the product including the water tank can be enhanced.

(3) In addition, the power supplied to the water electrolytic cell may be configured to use an external power source such as a home or an office, or an internal power source using a battery may be used so that the user may use the oral cleaner according to the present invention It is convenient to select the power source.

(4) By adding a water electrolytic cell to the existing mouthwasher, it is possible to easily manufacture the sanitizer, and the sanitizing effect can be improved while minimizing the additional cost.

(5) In addition, since it is not necessary to add additives such as salt, it is convenient to use, and it is possible to prevent the components of the oral cleanser from being damaged by the influence of salt or the like.

(6) Hydrogen is electrolyzed in the water tank including the water electrolytic cell and discharged immediately, so there is no loss of hydrogen into the air. Since the whole flow in the water tank is transferred to the water and then it is not necessary to pressurize, Hydrogen water can be used to increase the dissolved hydrogen concentration.

(7) On the other hand, the water electrolytic cell controls the intensity of the power applied to the pump and the electrolytic cell by the controller in proportion to the amount of hydrogen to be delivered. Therefore, when the amount of hydrogen to be delivered is large, And when the amount of water to be drained is low, a weak power source is applied to reduce the amount of hydrogenated water. Therefore, not only can a desired hydrogen amount be secured in a short time, but also hydrogenated water having a high hydrogen ion concentration can be obtained.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary terms, and the inventor should properly define the concept of the term to describe its invention in the best possible way The present invention should be construed in accordance with the spirit and scope of the present invention.

Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and are not intended to represent all of the technical ideas of the present invention. Thus, various equivalents And variations may be present.

The mouthwasher having a sterilizing effect according to the first embodiment of the present invention has the body B, the water tank 100, the water electrolytic bath 200, the pipe 300 (see FIG. 6) A handpiece 310, a flow controller 320, a pump 400, a power supply 500, and a controller 600.

Particularly, [Example 1] is constituted so that the hydrogen water electrolyzed in the water electrolytic bath 200 can be directly fed by being driven and controlled by the pump 400 so that it can be used for oral cleaning, It is possible to obtain sterilization effect at the same time as cleaning.

The controller 600 controls the intensity of power applied to the electrolyzer 200 and the pump 400 in proportion to the flow rate set by the flow controller 320 so that hydrogen The amount of hydrogen to be electrolyzed in the electrolytic cell 200 can be controlled in proportion to the increase in the amount of water, so that the desired amount of hydrogen can be sufficiently provided.

Hereinafter, this configuration will be described in more detail.

The main body B is a kind of housing for accommodating or supporting another structure according to the present invention to be described later as in Fig.

The water tank 100 provides a space for storing a predetermined flow rate therein as shown in Fig. It is preferable that the water tub 100 is configured to be capable of opening and closing the lid so as to provide water from the outside or clean the inside of the water tank 100. The water tank 100 is manufactured at a flow rate sufficient to supply water according to the cleaning capacity of the oral cleanser according to the present invention, and is installed in the main body B.

The hydrogen-containing electrolytic bath 200 receives water from the water bath 100 and electrolyzes hydrogen water as shown in FIGS. 2 and 6. The electrolytic cell 200 may be any electrolytic cell capable of electrolyzing water as water as it is supplied with power. For example, the hydrogen-containing electrolytic bath 200 has two compartments for separating electrolytic ions such as an ion exchange membrane (or an ion exchange resin) into an inner space thereof, and electrodes 220 can be constituted such that electrolytic ions are separated into the respective compartments by applying power to the electrodes 220, and hydrogen water can be obtained from the cathode side. Of course, it is also possible to provide two electrodes 220 having different polarities in one compartment to obtain hydrogenated water.

In the preferred embodiment of the present invention, the water electrolytic bath 200 is preferably installed in the water bath 100 as shown in Fig. This is because the water in the water tank 100 is used while the water electrolytic bath 200 is not exposed to the outside, so that water can be supplied directly, and the entire volume of the oral cleaner according to the present invention can be reduced. Of course, the water electrolytic bath 200 may be provided outside the water tub 100, and may be connected through a pipe or the like.

In particular, in the preferred embodiment of the present invention, the water electrolytic bath 200 is installed on the bottom surface of the water tank 100, as shown in FIG. 2, It is preferable to install the electrolytic solution so as to obtain hydrogenated water.

2, the water electrolytic bath 200 is preferably installed such that the inlet of water in the water tank 100 is located at a predetermined height H from the bottom of the water tank 100 . This is because, when water is filled in the water tank 100, foreign matter or the like contained in the water may sink, and in the present invention, to minimize the inflow of the settled foreign matter through the water electrolytic bath 200.

As shown in FIG. 2 and FIG. 6, one end of the pipe 300 is connected to the water electrolytic bath 200 and the other end of the pipe 300 is protruded out of the main body B to discharge hydrofluoric acid water out of the water tub 100 It is a pipe for. The pipe 300 is preferably made of a material made of copper or synthetic resin and made of a material which is not corroded or damaged even when exposed to water or hydrogen water. Preferably, the handpiece 310 to be described later can be conveniently used at a desired position by using a flexible hose.

In the drawing, the piping 300 shows a state where one side of the piping 300 is connected to the hydrogen-containing electrolytic bath 200 mounted on the bottom of the water tank 100, and the other end thereof is provided with a spray nozzle And discharges the electrolyzed hydrogen water from the hydrogen-containing electrolytic bath 200.

6, the handpiece 310 is connected to the other side of the pipeline 300 to allow the user to carry it to a desired place by hand and conveniently use the handpiece 310. The handpiece 310 has a cleaning nozzle So that water can be sprayed through the spray nozzle.

When the handpiece 310 is not in use, the handpiece 310 can be mounted on the main body B and can be taken out and used when necessary. At this time, To control the operation of the small water electrolytic bath 200 and the pump 400 to be described later. 6, a proximity switch 311 is mounted on the main body B at a position where the handpiece 310 is mounted, so that the switch operation is performed through the presence or absence of the handpiece 310 . Here, the proximity switch 311 is an ordinary switch manufactured to detect and turn on / off the object as it approaches, and includes various types of proximity switches such as a micro switch, a reed switch, a hall switch, Can be used in the present invention.

In the preferred embodiment of the present invention, the proximity switch 311 is preferably a Hall sensor and a magnet. At this time, the magnet is attached to the handpiece 310, and the hall sensor is mounted at a position where the magnetic field of the magnet can be detected when the handpiece 310 is placed on the main body B or inserted. Therefore, it is preferable that the water can be safely used even when there is water around.

The flow rate regulator 320 is for regulating the amount of hydrogen gas ejected through the handpiece 310 and may be mounted on the main body B or mounted on the handpiece 310 as shown in FIG. Or may be mounted on the main body B and the handpiece 310, respectively. Preferably, at least the handpiece 310 is mounted on the handpiece 310, and the flow rate is adjusted when the handpiece 310 is cleaned.

It is preferable that the flow rate regulator 320 is configured such that a flow rate corresponding to the changed resistance value is output when the flow rate is previously determined according to the resistance of the resistor using a variable resistor and the resistance of the resistor is changed by the flow rate controller 320. At this time, the change in flow rate according to the intensity of the resistance may be stored in advance in the controller 600 or may be used, or the resistance strength may be used as it is. This flow control will be described in detail again while explaining the controller 600. [

On the other hand, it is preferable that the resistance change is configured to be easily controllable through a variable resistor. Here, it is preferable to use a variable resistor manufactured by a conventional technique which is manufactured such that the resistance value changes according to turning of the knob in a rotary manner.

In a preferred embodiment of the present invention, it is preferable that the flow controller 320 is configured so that the user selects any one of the large, middle, and small three stages in advance. This is because, if the preset resistance is set for each stage and the flow rate appropriate for each stage is set in advance, the user can conveniently use only the desired number of steps, and the number of steps is rapidly adjusted It is possible to prevent a safety accident such as the discharge of a large amount of hydrogen at a flow rate in advance.

The pump 400 is installed in the above-described pipe 300 and is installed in the main body B so that hydrogen water can be jetted at a predetermined pressure from the injection nozzle, as shown in Figs. 2 and 6. Fig. In this case, it is preferable to use a pump having an appropriate number of revolutions and a discharge flow rate in consideration of the delivery pressure and the discharge flow rate of water.

This pump 400 is under the control of a controller 600 to be described later.

The power supply 500 supplies power to the above-described water electrolytic bath 200 and the pump 400 as shown in Figs. 2 and 6, respectively.

In a preferred embodiment of the present invention, the power supply 500 is preferably configured to be capable of supplying at least a direct current. This is because, in general, since the power source necessary for electrolyzing the hydrogen water in the electrolytic cell 200 is DC, it is possible to provide an appropriate DC power source. Of course, AC power may be supplied, or AC power may be converted into DC and supplied.

The pump 400 may be either a DC power supply or an AC power supply so that the power supply 500 can supply power to the pump 400 separately from the structure for driving the water electrolytic bath 200 It is preferable to construct a DC circuit or an AC circuit. Of course, when the direct current is used, the water electrolytic bath 200 and the pump 400 may be driven and controlled together through a single circuit.

As shown in FIG. 2, the power supply 500 is configured to receive an external power supply using an external power outlet or the like, and to obtain a required direct current or AC power.

The controller 600 controls the above-described water electrolytic bath 200 and the pump 400 as shown in Fig. 5 and Fig. 6. At this time, the controller 600 controls the flow rate according to the intensity of the power applied to the water electrolytic bath 200 and the pump 400 through the proximity switch 311 and the flow rate controller 320.

That is, when the controller 600 prepares to clean the handpiece 310 from the main body B, the proximity switch 311 is turned on, and when the signal is received, the controller 600 controls the hydrogen- 400 is ready to be powered. At this time, the power applied to the hydrogen-water electrolytic bath 200 and the pump 400 is determined by the power of the power source that varies depending on the flow rate regulated by the flow rate controller 320.

To be more specific, the flow rate regulator 320 is configured to cause the flow rate regulator 320 to discharge the hydrogen water through the handpiece 310 for cleaning, and after the cleaning, the flow rate controller 320, (320) to set the flow rate to "0 ". The controller 600 determines that the oral cleaner according to the present invention is to be used through the proximity switch 311. The controller 600 prepares to supply power from the power supply 500 to the water electrolytic bath 200 and the pump 400, As the flow rate is adjusted by rotating the flow rate controller 320, the intensity of the power applied to the electrolyzer 200 and the pump 400 is adjusted in proportion to the flow rate determined by the flow rate, 200 and the pump 400 is also increased.

When the water flow rate of the water is small, the water electrolytic bath 200 and the pump 400 are weakly driven. On the contrary, when the water flow rate is high, Is also strongly driven.

Here, the controller 600 inputs the intensity of the power to be applied to the water electrolyzer 200 and the pump 400 in advance in proportion to the flow rate controlled by the flow controller 320, that is, the resistance, And the power is supplied to the water electrolyzer 200 and the pump 400 at the intensity of the resistance adjusted by the flow controller 320 as described above. In this case, there is no problem in inputting the amount of change of the flow rate according to the intensity of the resistance to the controller 600. However, when the power is applied according to the resistance value detected by the flow rate controller 320, It is preferable to configure the flow regulator 320 such that the intensity of the resistance is weakened in order to discharge a large amount of flow rate. This is because the resistance is inversely proportional to the current and is proportional to the voltage, so a high resistance is required because a high current is required to conduct a large amount of flow.

Thus, the oral cleanser according to the present invention can pressurize the electrolyzed hydrogen water in the electrolyzed water tank 200 by the pump 400 and discharge the electrolyzed water through the pipe 300, and through the sterilization effect of the water, And massage effect as well as sterilizing effect can be obtained. At this time, the user can select the amount of hydrogen to be taken out, and electrolyzed an adequate amount of hydrogenated water in the hydrogenated water electrolytic bath 200 in proportion to the amount.

Here, the germicidal effect of hydrogen peroxide is disclosed in the microbicidal effect of the drinking water on oral bacteria submitted to the 2012 master's thesis (Kim, Jun-Beom, "Sterilization Effect of Hydrophobic Water on Oral Bacteria", Dankook University Dankook University, 2012 , PP4-10). Hydrophobic water was obtained by working tap water in Hydrogen Inc. (KwangJu, Kyunggi) for 5 minutes. Hydrophobic water was used and used within 10 minutes. In the anaerobic state, S. mutans , periodontal disease bacteria, F. nucleatum , P. gingivalis and T. forsythia were cultured in anaerobic condition. After reacting each organism with tap water and hydrogen peroxide for 30 seconds, . In the case of S. mutans , which is a phytopathogenic fungus, there was almost no change in tap water, but it decreased by 50% in the case of hydrogen peroxide . In addition, bactericidal effects were also observed in periodontal disease bacteria such as F. nucleatum , P. gingivalis and T. forsythia .

Industrial Applicability As described above, the present invention can be expected to have a sterilizing effect through sterilizing action of hydrogen water by using hydrogen water obtained through a water electrolyzer for oral cleaning. Particularly, since the high concentration of hydrogenated water immediately made in the electrolytic cell for hydrolysis is used, it is constructed so as to use the water. Therefore, the water is not converted into water in the tank capacity, Minimizing the loss of hydrogen production to the desired hydrogen content can increase the dissolved hydrogen concentration (PPM) of the hydrogen from the nozzle tip.

In the present invention, when the amount of hydrogen that flows out through the pump is high, the strength of the power supplied to the pump and the electrolytic cell is increased in proportion to the flow rate. Therefore, the necessary amount of hydrogen in the electrolytic cell is sufficiently electrolyzed, .

As shown in FIG. 3, the oral cleaner having a sterilizing effect according to [Embodiment 2] of the present invention is different from the [Embodiment 1] in the configuration of the power supply 500 '. Here, the same components as those in [Embodiment 1] will not be described in detail, and only the power supply 500 'as a difference configuration will be described.

[Embodiment 2] As shown in FIG. 3, the power supply unit 500 'is constructed as a built-in type that can be used by being mounted in a mouthwasher such as a battery. This is because, in the case of [Embodiment 1] receiving power from the outside through an outlet or the like, there is a limit to be used outdoors, such as leisure life, and there is a limit to the length of a cable even when used indoors, have.

Thus, according to the present invention, as in the second embodiment, the power supply 500 'is constructed as a built-in type so that it can be used not only in the length of the cable, but also in the outdoors. At this time, the power supply 500 'may be used for disposable use, but it is preferable that the power supply 500' is configured to be charged again.

4 and 5 show a state where the water electrolytic bath 200 is mounted on the bottom of the water tank 100 manufactured according to the present invention. At this time, as shown by arrows, the water electrolytic bath 200 is configured such that a sufficient amount of water can be supplied from the water tank 100 by forming a water inlet on both sides thereof. In addition, two electrodes 220 are installed in the water electrolytic bath 200 so as to allow the water to flow out to the water outlet 230 through which the water is discharged. The pipe 300 is connected to the drain hole 230.

As the water in the water tank 100 enters the water tank 100 from both sides of the water electrolytic cell and power is applied to the electrode 220, the electrolytic water is electrolyzed and discharged to the pipe 300 through the drain hole 230 do.
