Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a gargle device which mixes water and a chemical liquid to discharge a gargle liquid.

[Conventional technology]

Conventionally, as described in Japanese Utility Model Laid-Open No. 63-79916, a gargle device provided with a water nozzle for discharging water from a tip mouth portion and a chemical liquid nozzle for discharging a chemical liquid from a tip mouth portion, the water nozzle The mixed liquid nozzle is provided so that one end faces the tip end of the water nozzle, and the chemical solution hits the water at a right angle or an acute angle with respect to the discharge direction of the water discharged from the tip mouth part of the water nozzle and entering one end of the mixed liquid nozzle. The tip end of the chemical liquid nozzle is located at, and the ejection port at the other end of the mixed liquid nozzle is tilted upward at a predetermined angle to eject the mixed liquid of water and the chemical liquid from the ejection port. It has been known.

In the case of the gargle device, since the tip end of the water nozzle is separated from the inlet of the mixed liquid nozzle, there is no risk of the mixed liquid mixing into tap water even when the water is stopped, and the chemical liquid is discharged. There is an advantage that the power of the pump that operates is small.

[Problems to be solved by the device]

However, the first problem of the gargle device having the above structure is that when the tip end of the chemical solution nozzle is provided at a position apart from the inlet of the mixed solution nozzle, the chemical solution is caused by the flow of water when mixed with water. Not only does it scatter and not mix efficiently, but it also becomes unsanitary.

A second problem is that a pump is indispensable for discharging the liquid medicine from the tip opening of the liquid medicine nozzle. That is, since the chemicals are mixed at a right angle or an acute angle with respect to the discharge direction of water, it is necessary to discharge the chemicals at a positive pressure, and a pump is indispensable. However, when a pump is used, there is a problem that the gargle device becomes large and complicated, and the concentration of the mixed liquid changes due to the discharge force of the pump, which makes the concentration adjustment troublesome.

Therefore, an object of the present invention is to provide a mouthwash device having a simple structure that prevents the chemical liquid from splashing when mixing water and the chemical liquid and can mix the water and the chemical liquid without using a chemical liquid pump. is there.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the first invention comprises a water nozzle for discharging water, a chemical liquid nozzle for supplying a chemical liquid, and a mixed liquid nozzle for discharging a mixed liquid of water and a chemical liquid. The water nozzle is provided on the outer peripheral portion of the chemical liquid nozzle so that the water flows along the outer periphery of the chemical liquid nozzle, and the chemical liquid nozzle is projected forward from the water nozzle so that the discharged water causes a negative pressure near the tip of the chemical liquid nozzle. It is configured such that pressure is generated to suck the chemical liquid from the chemical liquid nozzle to mix it with water, and at the same time, the mixed liquid is sent to the inlet of the water mixture nozzle and the mixed liquid nozzle arranged to face the chemical liquid nozzle.

A second aspect of the present invention is the same as the first aspect, in which a hollow strip valve is installed inside the mixer, a chemical solution nozzle is formed inside the valve, and between the inner surface of the mixer and the outer surface of the valve. A water nozzle is formed, and the inner surface of the mixer and the outer surface of the valve are tapered surfaces that taper toward the tip,
An extension line of the tapered surface intersects in front of the chemical liquid nozzle.

[Action]

According to the first invention, the water discharged from the water nozzle surrounds the tip of the chemical liquid nozzle and shuts off the outside air, so that a negative pressure is generated inside the discharged water. Therefore, the negative pressure causes the chemical liquid to be sucked from the chemical liquid nozzle, and the chemical liquid is properly mixed with water without discharging the chemical liquid by the pump. Then, this mixed liquid is sent to the inlet of the mixed liquid nozzle, and discharged through the inside of this nozzle to the outside. Further, since the discharged water surrounds the chemical liquid, the chemical liquid does not scatter when the water and the chemical liquid are mixed.

Further, if the water nozzle is formed into a tapered shape as in the second invention, the water flowing around the surrounding can be completely surrounded by the chemical liquid flowing in the central portion, and the negative pressure can be efficiently generated inside the water. , It is possible to minimize the splash of chemicals and water.

〔Example〕

1 and 2 show a first embodiment of a gargle device according to the present invention.

A water supply valve 2 connected to the water pipe 1 is provided in the lower part of the gargle device, and when the pedal 3 is depressed, the water supply valve 2 is opened, and tap water having a predetermined pressure is supplied to the mixer 5 via the hose 4. Be guided.

The mixer 5 is horizontally fixed to the top plate 6 of the gargle device with screws 7. The water introducing pipe 8 and the chemical liquid introducing pipe 9 are connected to the lower portion of the mixer 5, and the hose 4 is connected to the water introducing pipe 8. Further, the chemical liquid introducing pipe 9 is provided with a check valve 16 described later.
Further, it is connected via a tube 11 to a chemical liquid tank 10 installed at the bottom of the gargle device.

A hollow valve 12 is screwed inside the mixer 5 so as to be adjustable in the front-rear direction, and the tip of the valve 12 slightly projects to the front of the mixer 5 (right side in FIG. 2). A chemical liquid nozzle 13 communicating with the chemical liquid introducing pipe 9 is formed inside the valve 12, and a rear end portion of the valve 12 is sealed with a plug 14. Between the tapered outer peripheral surface of the valve 12 and the tapered inner peripheral surface of the mixer 5, a gap communicating with the water introducing pipe 8 is provided. nozzle
Forming fifteen. That is, the water nozzle 15 is open to the outer peripheral portion of the chemical liquid nozzle 13, and the chemical liquid nozzle 13 projects forward from the opening of the water nozzle 15. The extended line of the tapered surface which constitutes the water nozzle 15 intersects at the O point in front of the chemical liquid nozzle 13 as shown by the alternate long and short dash line in FIG. Therefore, the water discharged from the water nozzle 15 surrounds the chemical liquid nozzle 13, prevents the outside air from flowing into the inside of the discharge water, and generates a negative pressure in the vicinity of the tip of the chemical liquid nozzle 13 to discharge the chemical liquid to the chemical liquid nozzle. By sucking through the mouth 13, the water and the drug solution can be mixed efficiently.

The check valve 16 is equipped with a diaphragm 17 inside. The upper chamber 18 of the diaphragm 17 has a connecting pipe 20 and a hose 21.
Is connected to a communication hole 5a that is opened to the side of the mixer 5 through the. This communication hole 5a communicates with the water nozzle 15,
The water pressure of the water nozzle 15 acts on the upper chamber 18. The lower chamber 19 of the diaphragm 17 is connected to the chemical solution nozzle 13 through the chemical solution introducing pipe 9. A valve body 22 is provided in the lower chamber 19.
Are arranged in a state of being urged upward by a spring 23, and a gasket 24 attached to the outer periphery of the valve body 22 normally closes the valve opening 25. The upper end surface of the valve element 22 is always in contact with the lower surface of the diaphragm 17. The connection port 26 formed at the lower end of the check valve 16 is connected to the chemical liquid tank 10 via the tube 11. Now, when tap water is supplied to the water nozzle 15, a part of the tap water is supplied to the connecting pipe 20 and the hose 21.
Flow into the upper chamber 18 via the, and the water pressure causes the diaphragm 17 to bend downward. Since the valve body 22 moves downward in conjunction with this, the gasket 24 opens the valve opening 25,
The drug solution in 10 passes through the tube 11 and the check valve 16 and the drug solution nozzle
Supplied to 13. In this way, the check valve 16 is opened by utilizing not only the negative pressure generated in the chemical liquid nozzle 13 but also the water pressure of the water nozzle 15, so that the chemical liquid can be quickly supplied to the chemical liquid nozzle 13.

In front of the chemical liquid nozzle 13 and the water nozzle 15, the inflow ports 27a of the mixed liquid nozzle 27 are arranged so as to face each other at regular intervals. The mixed liquid nozzle 27 stands obliquely upward from the inflow port 27a and is a support plate fixed to the top plate 6 together with the mixer 5.
Supported by 28. The mixed liquid that has flowed into the inflow port 27a of the mixed liquid nozzle 27 flows through the mixed liquid nozzle 27 and is jetted upward from the jet nozzle 27b. By including this mixed liquid in the mouth, it is possible to gargle.

A discharge hole is provided at the lower end of a support plate 28 supporting the mixed liquid nozzle 27.
28a is formed, and when the water supply valve 2 is closed and the discharge of water is stopped, the mixed liquid accumulated in the mixed liquid nozzle 27 drops from the inlet 27a onto the support plate 28, and further from the discharge hole 28a to the ceiling. It is discharged onto the plate 6. Therefore, there is no possibility that the mixed liquid is accidentally mixed in the tap water. In addition, the check valve 16 is closed when the discharge of water is stopped, so that the chemical liquid is discharged from the chemical liquid nozzle.
It does not leak from the tip of 13 and the chemical solution does not mix with water.

Further, in the case of a gargle device, it is desirable that the chemical solution flows out after the water starts to be discharged, but a check valve 16 that opens with the water pressure of the water nozzle 15 is provided as a check valve in the chemical solution passage. For example, since the chemical solution will flow out after water begins to be discharged,
There is no risk that the chemical solution will flow out first. Further, in the case of a gargle device using a conventional ejector, there is a problem that the check valve provided in the chemical liquid passage does not open easily and the outflow of the chemical liquid is delayed too much, but in the check valve 16 the negative pressure of the chemical liquid is low. But valve opening 25
Since the open, the outflow of the drug solution is not too late.

As described above, in the case of the gargle device, water flows along the outer periphery of the chemical liquid nozzle 13, and the water surrounds the chemical liquid nozzle 13 to block the outside air, so that a negative pressure is applied to the vicinity of the tip of the chemical liquid nozzle 13. Occurs. Therefore, the chemical solution is supplied from the chemical solution tank 10 to the chemical solution nozzle.
It is sucked out via 13 and mixed with water. Therefore, there is no need for a pump for discharging the chemical liquid as in the conventional case,
The device can be made smaller and simpler. In addition, because the pump is no longer needed, the chemical concentration in the mixed solution can be determined only by the flow rate of water, so that the concentration can be determined by both factors such as the flow rate of water and pump efficiency as in the past. In comparison, the density adjustment is easy. The flow rate of water may be adjusted by a flow rate adjusting valve (not shown) provided in the middle of the water supply valve 2 and the water introducing pipe 8, or the valve 12 screwed to the mixer 5 may be screwed. Adjust the amount, valve 12 and mixer 5
The opening area of the water nozzle 15 formed in the gap between and may be adjusted.

FIG. 3 shows a second embodiment of the present invention, in which the same parts as those in the first embodiment are designated by the same reference numerals and their description is omitted.

In this embodiment, a thin tube 29 is connected to the tip of the valve 12 and the tube 29 is projected longer than the opening of the water nozzle 15. In this case, since water flows along the outer circumference of the pipe 29 as shown by the arrow, a larger negative pressure can be generated at the tip of the pipe 29 as compared with the first embodiment, and the chemical liquid can be efficiently sucked. There is.

FIG. 4 shows a third embodiment of the present invention. The same parts as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

In this embodiment, a bulging portion 30b is integrally provided near the inflow port 30a of the mixed liquid nozzle 30, and the tip portion of the pipe 31 connected to the valve 12 is inserted into the bulging portion 30b. In this case, the water flowing along the outer periphery of the pipe 31 is divided into the inflow port 30a side and the bulging portion 30b side at the tip of the pipe 31, and especially the water flowing along the inner surface of the bulging portion 30b is Since the rear end opening of the bulging portion 30b is water-sealed, almost no outside air flows into the inside of the bulging portion 30b.
Therefore, a negative pressure larger than that in the second embodiment can be generated at the tip of the pipe 31, and the suction efficiency of the chemical liquid is further improved.

In the above embodiment, a diaphragm is used as a check valve for preventing the backflow of the chemical liquid, and the valve is opened by utilizing the water pressure of the water nozzle. However, instead of this, the valve is actually opened.
A diaphragm-type check valve that opens only with negative pressure as described in Japanese Patent No. 9 may be used, or a known check valve that does not utilize the water pressure of the diaphragm or the water nozzle may be used.

[Effect of device]

As is clear from the above description, according to the present invention, it is possible to realize a gargling device capable of properly mixing a chemical liquid and water with a simple and small structure without the need for a pump for discharging the chemical liquid. Moreover, since the drug solution is surrounded by water, there is no risk of the drug solution splashing when mixing with water, and the drug solution can be mixed very efficiently and is hygienic.
