Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gargle apparatus for mixing a tap water and a chemical solution to discharge a gargle.

[0002]

2. Description of the Related Art Conventionally, according to Japanese Utility Model Laid-Open Publication No. 2-28215, a first flow path which is directed from a water outlet of a water supply pipe in the same direction as water discharge direction and has a water inlet at one end, and An aspirator provided with a second flow path formed in a direction perpendicular to the flow path and communicating with the flow path; separating the water outlet of the water supply pipe from the water inlet of the aspirator; The liquid supply pressure of the tap water entering the first flow path draws the chemical liquid into the first flow path through the second flow path to form a mixed gargle of the tap water and the chemical liquid; A gargle device in which a gargle liquid discharge nozzle is communicated with the other end of the first flow path has been proposed.

In such a gargle apparatus, since the water supply pipe and the aspirator are separated from each other, it is possible to reliably prevent the chemical solution or the gargle from flowing back into the water supply pipe. Further, the above-mentioned gargle device uses a negative pressure generated in an area enlarged portion of the first flow path to suck the chemical liquid by the flow rate of the water flowing through the first flow path of the aspirator. A mixed gargle of a chemical and water can be made without forcing it into the aspirator.

[0004]

By the way, in the gargle having the above structure, the second flow path through which the chemical solution flows is connected at a right angle to the first flow path through which water flows. In other words, the structure is such that the chemical liquid flows into the water at one point from the outer circumferential direction. Therefore, even if a negative pressure is generated in the first flow path due to the flow rate of the water, the suction efficiency of the chemical solution is very poor.
In addition, the opening of the second flow path that opens to the first flow path needs to be formed small so that water does not directly enter, so that the suction amount of the chemical solution itself is also small. As a result, the dilution ratio between water and the chemical solution becomes unstable, and the dilution ratio cannot be increased.

Accordingly, an object of the present invention is to provide a gargle device that can improve the suction efficiency and suction amount of a chemical solution, stabilize the dilution ratio between water and the chemical solution, and can freely increase the dilution ratio. To provide.

[0006]

In order to achieve the above-mentioned object, the present invention provides a water nozzle which is supplied with tap water and discharges water from a tip, and an inlet at one end is spaced from the tip of the water nozzle. In the gargle apparatus, which is provided with a mixer which mixes the chemical solution and water supplied from the chemical solution tank at an intermediate portion and discharges a gargle mixed with water and the chemical solution from the other end discharge port, The vessel has a water passage through which water that has entered from the inlet once flows, and a chemical passage that opens in the same direction as the flow direction of the water is formed around the entire outer peripheral portion of the water passage, and flows through the water passage. Provided is a gargle device that draws a drug solution from a drug solution channel by a water suction effect and mixes the water and the drug solution.

[0007] When water is discharged from the water nozzle, the water enters the inlet of the mixer and passes through a water passage provided in the mixer. At this time, the chemical solution is drawn out from the opening of the chemical solution passage provided on the outer peripheral portion of the water passage to the water passage by a suction effect of water flowing through the water passage. The gargle mixed in this way is discharged from the other end discharge port of the mixer, and gargle can be performed by including this in the port. In the present invention, the chemical solution is sucked in the same direction as the direction in which the water flows and from the entire circumference thereof. Suction efficiency increases. In addition, since the opening of the chemical solution passage is opened in the same direction as the direction in which water flows, there is no possibility that water jumps into the chemical solution passage, and the area of the opening of the chemical solution passage can be increased. For this reason, the suction amount of the chemical solution itself can be increased, and the dilution ratio between water and the chemical solution can be stabilized, and the dilution ratio can be freely increased.

According to a second aspect of the present invention, a receiver is provided at one end of the mixer for receiving water that cannot completely enter the inlet, and a supply passage for sucking water collected in the receiver and leading to the water passage. It may be provided. After the water discharged from the water nozzle flies in the air, it enters the inlet of the mixer, but a part of the water may not be able to enter the mixer. This water must be discharged to the outside through a drain passage. However, in the case of a gargle device in which it is difficult to provide such a drain passage (for example, a wall-mounted gargle device), it is difficult to provide a water nozzle and a mixer separately as in the present invention.
On the other hand, as described in claim 2, water that cannot enter the mixer is received by the receiving device, and the water is sucked into the mixer,
If it is discharged as a gargle with other water, there is no need to provide a drainage passage. Therefore, it can be applied to a gargle device in which it is difficult to provide a drain passage.

According to a third aspect of the present invention, a cylindrical partition wall is provided between the water passage of the mixer and the chemical liquid passage, and a water supply hole through which a part of the water flowing in the water passage is sent to the chemical liquid passage side in the cylindrical partition wall. Is desirably provided. Although the water flows in the water passage at a high speed, if a part of the kinetic energy can be transmitted to the chemical solution flowing through the chemical solution passage, the suction of the chemical solution can be performed more efficiently. In view of this, in claim 3, a water supply hole is provided in a cylindrical partition partitioning between the water passage and the chemical liquid passage, and a part of the kinetic energy of water is transmitted to the chemical liquid so that the chemical liquid is efficiently sucked out. is there.

It is preferable that the chemical liquid tank is installed above the mixer and the chemical liquid is supplied to the chemical liquid passage of the mixer using the head pressure of the chemical liquid. As described above, the water discharged from the water nozzle flies in the air and then enters the inlet of the mixer, so that the kinetic energy of the water flowing in the mixer is smaller than the kinetic energy of the water flowing through the water nozzle. . Therefore, the suction force of the chemical solution by the mixer cannot be increased so much. On the other hand, when the chemical tank is installed below the mixer, the chemical must be drawn from the chemical tank to the mixer, and between the chemical tank and the mixer, a chemical hose, a flow control valve, Since fluid resistance such as a check valve acts, it is difficult to efficiently supply a chemical solution to the mixer without using a chemical pump. Therefore, by installing the chemical solution tank above the mixer, the head pressure of the chemical solution works effectively, and without using means such as a chemical solution pump,
The chemical can be efficiently supplied to the mixer.

[0011]

1 to 5 show a first embodiment of a gargle device according to the present invention. The gargle device of this embodiment is of a wall-mounted type, and is attached to a wall surface W such as a washroom. The gargle device includes a main body frame 1 fixed to a wall surface W, and a cover 2 detachably mounted on a front surface of the main frame 1. A chemical solution tank 3 containing a chemical solution is housed therein.

One end of a chemical pipe 6 is inserted into the chemical tank 3, and the other end of the chemical pipe 6 is connected via a flow control valve 7 and a check valve 8 to a water supply attached to a lower portion of the main body frame 1. It is connected to an on-off valve 5 for supplying liquid. The check valve 8 is provided so as to allow only the flow of the chemical from the chemical tank 3 to the opening / closing valve 5. As shown in FIG. 3, the opening and closing valve 5 has a connection port 5 connected to the water pipe 4.
b and a connection port 5c connected to the chemical pipe 6 are provided. By pushing a push button 5a protruding forward from the cover 2, a water passage and a chemical passage are simultaneously opened, and the push button 5a is pushed. At the same time as the pressure is released, the water passage and the chemical solution passage can be simultaneously closed by the spring 5d. That is, the water supplied from the water pipe 4 is supplied to a water nozzle 14 described below, and at the same time, the chemical supplied from the chemical tank 3 is supplied to a mixer 20 described later.

The open / close valve 5 is connected to a joint 12 via a water pipe 10 and a chemical liquid pipe 11 (see FIG. 1).
A flow regulating valve 13 is provided in the water pipe 10. An L-shaped water nozzle 14 is connected to the joint 12 so as to be rotatable in the horizontal direction. A hole 14 a through which tap water flows through the joint 12 is provided at the center of the water nozzle 14.
Is formed, and the water squeezed finely from the nozzle port 14b at the tip of the nozzle urges vigorously in the horizontal direction. A chemical solution flow hole 14c is formed in the water nozzle 14 in parallel with the water flow hole 14a, and a chemical solution is supplied to the chemical solution flow hole 14c via the joint 12. The chemical solution flow hole 14c is connected to the mixer 20 via the connection pipe 15.

As shown in FIGS. 4 and 5, an annular holder 22 is formed integrally with the mixer 20 via a connecting portion 21, and the holder 22 is attached to the tip of the water nozzle 14. They are fitted and fixed by fixing screws 34.
The mixer 20 has a wide-mouthed inlet 23 that faces the nozzle port 14 b of the water nozzle 14 at a position separated by a predetermined distance L and that receives the water discharged from the water nozzle 14. The holder 22 also has a function of matching the center of the water nozzle 14 with the center of the inflow port 23. Mixer 20
A small-diameter water passage 24 through which water entering from the inflow port 23 flows, and an annular chemical liquid passage 26 which is separated from the outer periphery of the water passage 24 via a cylindrical partition wall 25 are formed inside. The chemical solution is supplied to the chemical solution passage 26 through the chemical solution flow hole 14 c of the water nozzle 14, the connection pipe 15, and the communication hole 33 formed in the connecting portion 21 of the mixer 20. The opening 26 a of the chemical liquid passage 26 opens in the same direction as the flowing direction of water with respect to the mixing portion 29 provided at the end of the water passage 24. An outlet 27 is provided at an end of the mixer 20 opposite to the inlet 23, and a gargle discharge nozzle 28 is connected to the outlet 27. The tip discharge port 28a of the gargle discharge nozzle 28 is formed upward.

The cylindrical partition wall 25 is provided with a small water supply hole 30 which is inclined from the inside to the outside at an acute angle with respect to the flow direction of water. The water supply hole 30 has a function of sending out a part of the water flowing in the water passage 24 to the side of the chemical solution passage 26 to thereby push out the chemical solution to the mixing unit 29 by the jet pump action. Also, the mixer 20
A receiver 31 for receiving water that cannot enter the inflow port 23 is attached to the inflow port 23. The receiving tool 31 surrounds the periphery of the inflow port 23 so that the water scattered at the inflow port 23 can be received. Between the receiving member 31 and the water passage 24, the water accumulated in the receiving member 31 is supplied to the water passage 24.
A supply pipe 32 for leading to is connected.

Next, the operation of the gargle having the above configuration will be described. First, the chemical in the chemical tank 3 is led to the chemical passage 26 of the mixer 20. In this state, when the push button 5a of the on-off valve 5 is pressed, the water supplied from the water pipe 4 is jetted from the water nozzle 14 and the
Into the inflow port 23. The water that has entered through the inflow port 23 flows through the water passage 24 narrowed at a small diameter at a high speed. Water passage 24
The water flowing at a high speed causes the passage area to increase in the mixing section 29, causing a pressure drop. The suction action causes the chemical to be drawn in from the chemical passage 26. Therefore, the water and the chemical solution are properly mixed in the mixing section 29, and the mixed gargle passes from the outlet 27 of the mixer 20 through the discharge nozzle 28 to the discharge port 2.
It is possible to gargle by discharging upward from 8a and including the gargle in the mouth.

The opening 26a of the chemical solution passage 26 is
Since the opening is formed in an annular shape around the entire outer peripheral portion of 4, the liquid is sucked from the entire peripheral portion of the water flowing through the central portion. Therefore, compared with the conventional aspirator that draws the liquid medicine from one point on the outer periphery, the suction efficiency of the liquid medicine is remarkably improved. Further, since the opening 26a is opened in the same direction as the direction in which water flows, even if the opening area of the opening 26a is increased, water does not directly enter, and the amount of suction of the chemical solution can be increased. As a result, the dilution ratio between water and the chemical solution is stabilized, and the dilution ratio can be increased. The dilution rate is
It can be adjusted freely by a flow control valve 7 provided in the middle of the chemical liquid pipe 6.

Further, since water is fed from the water passage 24 toward the chemical liquid passage 26 through the water supply hole 30 provided in the cylindrical partition wall 35, the chemical liquid is supplied to the mixing section 29 by the jet pump action. It can be extruded efficiently. Further, since the chemical tank 3 is provided above the mixer 20, the chemical liquid passage 26 is utilized by utilizing the head pressure of the chemical.
Can be supplied smoothly. for that reason,
Even if the negative pressure generated in the mixing section 29 is not so high, the chemical solution and the water can be efficiently mixed.

Most of the water spouted from the water nozzle 14 enters the inflow port 23, but part of the water may splatter or bounce. Such water that cannot enter the inflow port 23 is received by the receiver 31 and stored. Then, the accumulated water is sucked into the water passage 24 via the supply pipe 32 by the water flowing through the water passage 24 at a high speed, so that there is no need to provide a special drain passage. In particular, in the case of a wall-mounted gargle, it is difficult to provide a drain passage, which is effective.

The present invention is not limited to the above embodiment. In the above embodiment, an example of a wall-mounted gargle was shown, but it goes without saying that the invention can be applied to a so-called floor-mounted gargle. Therefore, the chemical liquid tank 3 is not limited to the case where it is installed above the mixer 20. In addition, in order to install the water nozzle and the mixer at a fixed distance L and to match the center thereof, the connecting portion is extended from the mixer, and the water nozzle is attached to a holder provided at an end of the connecting portion. Although the distal end is fixed, the present invention is not limited to this. For example, a connecting member for connecting the water nozzle and the mixer may be separately provided.

[0021]

As is apparent from the above description, according to the present invention, a water passage through which water once enters the mixer through the inlet and the same direction as the water flows over the entire outer peripheral portion thereof. Is formed in the same direction as the direction in which the water flows, and is drawn from the entire circumference. As compared with the case of sucking the liquid, the suction efficiency of the chemical solution is increased. Further, since the opening of the chemical liquid passage is opened in the same direction as the direction in which the water flows, there is no possibility that water jumps into the chemical liquid passage, and the area of the opening of the chemical liquid passage can be increased. Therefore, the suction amount of the chemical solution itself can be increased, and the dilution ratio between water and the chemical solution can be stabilized, and the dilution ratio can be freely increased.
