Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a gargling device that automatically mixes a medicinal solution and water appropriately.

[Prior art] Conventionally, water is jetted out from a nozzle, and the negative pressure generated in a suction chamber by the jet (hereinafter referred to as jet negative pressure) is used to suck a chemical solution from a chemical tank, and the chemical solution and water are combined. For example, a gargling device designed to mix the following is known from Japanese Utility Model Publication No. 52-18636. That is, in this gargling device, a chemical solution tank is installed in the housing, and the structure is such that the drug solution is sucked up through a conduit that hangs inside the drug solution tank, and the drug solution is guided to the suction mixing section via a check valve. ing.

[The problem that the idea aims to solve]

However, since the above structure requires a housing, the device becomes large and has the disadvantage that it cannot be installed in a washbasin unit where installation space is limited. In addition, as mentioned above, suction of the chemical liquid is performed by the negative pressure of the water jet, but since the chemical liquid tank is installed below the suction mixing section, the liquid suction force is reduced by the water head pressure. This, together with the pressure loss in the conduit leading from the chemical tank to the suction mixing section, resulted in a further decrease in suction force. As a result, it is not possible to aspirate the medicinal solution by simply flushing a small amount of water, and even if the medicinal solution can be aspirated, there is a time delay between the time the water flows out and the medicinal solution being sucked out, and the suction mixing section does not function adequately. There was a problem.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a gargling device that has a compact structure, can smoothly suck a medicinal solution from a medicinal solution tank, and can prevent delays in sucking the medicinal solution.

[Means to solve the problem]

In order to achieve the above object, the gargling device of the present invention is attached to the gargling device main body via a branch pipe to a water faucet, and water is supplied from the water faucet to the gargling device main body through the branch pipe. Inside the gargling device main body, a first valve body for opening and closing the water inlet is provided upstream of the suction mixing part, and a second valve body for opening and closing the medicinal solution inlet is provided upstream of the suction mixing part. A drug solution tank attachment port is formed above the suction mixing section of the device main body to communicate with the drug solution inlet and to which the lower end opening of the drug solution tank storing the drug solution can be attached and detached, and the device main body has a drug solution tank attachment port which is connected to the drug solution inlet and which is detachable from the lower end opening of the drug solution tank storing the drug solution. A discharge pipe having a discharge port is provided on the downstream side.

[Effect]

Water is sent from the faucet to the gargling device main body via a branch pipe, and the medicinal solution is sent from the lower end opening of the drug solution tank to the gargling device main body via the attachment port. Then, since the water is guided to the suction mixing section through the first valve body, the medicinal liquid is sucked into the suction mixing section through the second valve body by the ejected negative pressure, and is properly mixed with water. The mixed liquid is then discharged from the discharge port through the discharge pipe. In this way, the medicinal solution is directly supplied to the gargling device body without passing through the conduit, and since the medicinal solution tank is located above the suction mixing section, the negative pressure in the suction mixing section is small due to the water head pressure. can be easily mixed properly.

〔Example〕

FIGS. 1 to 4 show an example in which the gargling device according to the present invention is applied to an automatic gargle that is attached to a water faucet via a branch pipe. In the figure, 1 is a water faucet, and 4 is a branch valve. The branch valve 4 is attached to the handle attachment part 2 of the water faucet 1, and water is constantly supplied to the gargling device 10 through a branch pipe 6. Further, by turning the handle 5 to open the valve port of the water supply faucet 1, water can be discharged from the water supply port 3.

A gargling device 10 is attached to the tip of the branch pipe 6 in a perpendicular direction, and water in the branch pipe 6 is supplied to the gargling device 10. That is, the main body 11 of the gargling device 10 has a connecting hole 1 as shown in FIG.
2 is formed, and a branch pipe 6 is connected to this connecting hole 12.
The branch pipe 6 and the gargling device main body 11 are fixed in communication by inserting the distal end thereof in a watertight manner and screwing the mounting screw 7 into the distal end thereof.

As shown in FIG. 3, the gargling device main body 11 is equipped with a spindle 20, a liquid medicine tank 40, a suction mixing section 50, and a pipe 60. An operating lever 21 is fixed to the base end of the spindle 20 with a set screw 22, and a male screw 2 provided near the end
3 is screwed into the female thread 13 of the gargling device main body 11, the spindle 20 can move back and forth in the front and rear directions. At the center of the spindle 20 is a first valve body 24 such as a gasket for opening and closing the water inlet 14 formed inside the gargling device main body 11.
is installed, and the water that has passed through the water inlet 14 is adjusted in flow rate by a water volume adjustment valve 25 provided at the bottom of the gargling device main body 11, and then flows through the water communication passage 15 to the suction mixing section 50. be guided.

A chemical liquid inlet 1 is provided at the tip of the spindle 20.
A second valve body 27 for opening and closing the valve 6 is provided. That is, at the tip of the spindle 20, as shown in FIG. 4, there is a stepped shaft 26 screwed and fixed to the tip of the spindle 20, and a second valve consisting of a sleeve fitted over the tip of the shaft 26. body 27
, a gasket 28 attached to the right end of the second valve body 27 , a washer 29 in contact with the left end surface of the second valve body 27 , and a large spring force interposed between the washer 29 and the spindle 20 . A spring 30 is provided. The spring 30 presses the second valve body 27 to the right via the washer 29, and the gasket 28
is pressed against the chemical liquid inlet 16 to close the valve. That is, when the valve is closed, the stepped portion 2a of the shaft 26 is separated from the washer 29, so the spring force of the spring 30 acts on the second valve body 27 via the washer 29, providing a valve-closing force. From this state, spindle 20
When the is moved to the left, the shaft 26 also moves to the left, and the washer 29 is pulled to the left by the stepped portion 26a of the shaft 26, and the washer 29 and the second valve body 2
7 are separated, and the valve-closing force applied to the second valve body 27 is released. Therefore, the second valve body 27 becomes movable in the axial direction, and as described later, the second valve body 27 opens the chemical liquid inlet 16 due to the negative pressure generated in the suction mixing section 50, and the chemical liquid flows through the chemical liquid inlet. 16 and is guided to the suction mixing section 50 via the chemical liquid communication path 17.

A chemical liquid adjustment valve 31 is provided at a position facing the spindle 20, and the opening degree of the chemical liquid inlet 16 can be adjusted by this valve 31. At the top of the gargling device main body 11, there is a medical solution inlet 1.
A chemical solution tank attachment port 18 is provided in a protruding manner and communicates with the chemical solution tank 6 , and a lower end opening 42 of the chemical solution tank 40 is removably screwed into this attachment port 18 via a seal ring 41 . It is guided to the chemical liquid inlet 16 via the regulating valve 31. The chemical liquid tank 40 is made of a transparent or translucent material so that the remaining amount of the chemical liquid can be visually checked, and a lid 43 having an air hole 44 is attached to the upper end thereof. A sealing valve 45 is installed in the opening 42 to prevent liquid leakage when the chemical tank 40 is removed, and a push-up pin 46 and a filter 47 are installed in the chemical tank attachment port 18 to push up the valve 45 to open it. and are arranged. This filter 47 prevents impurities from flowing into the gargling device main body 11 even if impurities should be mixed into the chemical solution tank 40 .

As mentioned above, the chemical solution tank 40 is connected to the gargling device main body 1.
1, especially directly above the suction mixing section 50, there is no need for a conventional conduit for guiding the chemical solution, which reduces the pressure loss of the chemical solution flowing inside the conduit, and reduces the water head of the chemical solution. Since the chemical liquid can be guided to the suction mixing section 50 using pressure, it becomes possible to mix water and the chemical liquid more efficiently.

The suction mixing unit 50 includes a differential user 51 that is detachably attached to a cavity 19 formed in the gargling device main body 11, an orifice 52 that is screwed into the differential user 51, and an orifice 52 that is attached to the left end of the orifice 52. It is composed of a screen 53 that removes dirt, rust, etc. from tap water. Therefore, even if clogging occurs inside the orifice 52, the orifice 52 and screen 53 can be removed together by pulling out the differential user 51 from the space 19, making repair or replacement easy. be. The water introduced into the orifice 52 through the water communication passage 15 is ejected from the small-diameter nozzle 52a into the throat portion 51a at high speed, thereby generating negative pressure in the suction chamber 54. The pressure causes the chemical liquid to be sucked through the chemical liquid communication path 17 and mixed with water. The mixed liquid is sent to the discharge pipe 60 through the throat portion 51a of the diffuser 51, and is discharged upward from the discharge port 61.

Note that the pipe 60 is rotatably attached to the gargling device main body 11, and the position of the discharge port 61 can be changed as desired.

Description of Operation Next, the operation of the gargle device 10 having the above configuration will be explained. First, the water amount adjustment valve 25 and the chemical liquid adjustment valve 31 are adjusted to obtain a desired mixing ratio. When the operating lever 21 is opened, the first valve body 24 and the second valve body 27 open the water inlet 14 and the chemical liquid inlet 16, respectively. At this time, the first valve body 24 opens at the same time as the operation lever 21 is opened, but the second valve body 27 opens when there is a gap δ between the stepped portion 26a of the shaft 26 and the washer 29, as shown in FIG. Since the first valve body 24 is present, the valve closing force is released following the opening of the first valve body 24. When the first valve body 24 is opened, water flows into the suction mixing section 50 through the water inlet 14 and the water communication passage 15, and the suction mixing section 50 generates negative pressure in the suction chamber 54 by jetting out water. The chemical solution is sucked and mixed with water at the throat portion 51a. As described above, the mixed liquid is discharged upward from the discharge port 61 through the pipe 60, and can be gargled directly without receiving it with a pot or the like.

When sucking the chemical liquid, the closing force of the second valve body 27 is zero, so the chemical liquid is suctioned without resistance.Moreover, since the chemical liquid tank 40 is installed above the suction mixing section 50, the chemical liquid is absorbed. Water head pressure is added, and as a result, suction is further smoothly performed by the two forces of suction negative pressure and water head pressure. Therefore, the mixed liquid can be discharged from the discharge port 61 of the pipe 60 almost simultaneously with the opening operation of the operating lever 21, and the operation followability is significantly improved compared to the conventional method, and even with a small amount of water. It becomes possible to aspirate the chemical liquid and obtain a wide range of mixing ratios.

On the other hand, when the operating lever 21 is operated to close, the washer 2 whose position is regulated by the stepped portion 26a of the shaft 26 is moved.
9 contacts the second valve body 27 and causes the spring force of the spring 30 to act on the second valve body 27, so that the chemical liquid inlet 16 is closed, and then the water inlet 14 is closed.

Other Embodiments In the above embodiment, the second valve body 27 is connected to the spindle 2.
0, and the closing force of the second valve body 27 is obtained by the spring 30. However, if the dimensional tolerance is small, the second valve body 27 can be moved in the axial direction with respect to the first valve body 24. Similarly, it may be configured to be integrally attached to the spindle 20. On the contrary, the first valve body 24
Similarly to the second valve body 27, it may be provided movably with respect to the spindle 20, and the valve closing force may be obtained by the spring force of the spring. In either case, the closing force of the first and second valve bodies 24 and 27 can be set arbitrarily, so that when the spindle 20 is closed, the water inlet 14 and the chemical solution inlet 16 are reliably closed, preventing water leakage. It is possible to reliably prevent chemical liquid leakage or backflow of water into the chemical liquid tank 40.

Furthermore, in the present invention, the valve for opening and closing the chemical liquid inlet 16 is not limited to the second valve body 27 provided on the spindle 20, but may be used in the suction mixing part 50 as in the conventional case.
A check valve may be provided that opens only when negative pressure is generated.

FIG. 5 shows another embodiment of the present invention, in which the lower end opening 42 of the chemical liquid tank 40 is closed with a sheet 48 that can be freely pierced, and the sheet 48 is inserted into the chemical liquid tank attachment port 18 when the chemical liquid tank 40 is attached. It is equipped with a pin 49 that pierces through and opens. In this case, there is no need to provide the sealing valve 45 in the lower end opening 42 as in the above embodiment, and if the chemical in the chemical tank 40 is completely used, the chemical tank 40 can be replaced with a new one. Therefore, handling becomes easy.

[Effect of idea]

As is clear from the above explanation, according to the present invention, by attaching the chemical tank directly to the upper part of the main body,
The device can be made smaller by eliminating the conduit, and the pressure loss of the chemical solution is small, and the chemical solution can be smoothly guided to the suction mixing section by using the water head pressure of the chemical solution.

In addition, by attaching the main unit to the water faucet via a branch pipe, there is no need for components such as a housing to support the main unit, and there is also no need for a water supply conduit, making it suitable for washbasin units with limited installation space. Can be installed.

Furthermore, by using the first valve body that opens and closes the water inlet and the second valve body that opens and closes the chemical solution inlet, wasteful outflow of water and chemical solution can be prevented.

Furthermore, by holding the mixed liquid discharged from the discharge pipe in the mouth, the user can easily gargle without using a tip or the like.
