Description

[Detailed Description of the Invention] The present invention relates to a mechanism for adjusting the concentration of gargling liquid used in a gargle.

Originally, gargles introduced water from the tap through a water supply pipe, and due to the ventilating effect of the water, gargle was pumped up from the gargle container at the bottom of the gargle via a gargle liquid pipe and mixed at the same time to mix the gargle. The liquid is sprayed out from a spray nozzle provided at the top of the main body. The gargling mixture used is a mixture of ordinary water and gargling liquid at a ratio of around 100:1, but the mixing ratio is conventionally controlled by an inhaler, and depends on the location of the gargle, etc. The intake device had to be fine-tuned one by one depending on various conditions, and it had to be constantly checked to see if the mixture ratio was appropriate.

In view of these points, the present invention provides a concentration detection device for detecting the concentration of the gargling fluid near the mixing pipe located at the connection between the water supply pipe and the gargling fluid pipe, and also provides a concentration detection device for detecting the concentration of the gargling fluid. Therefore, a pump for regulating the pumping speed is provided in the gargling liquid pipe, and a gargling liquid mixture in which the mixing ratio of water and gargling liquid is always constant is created by the cooperation of the pump and the concentration detecting device. The purpose is to

The present invention will be described in detail below with reference to one embodiment. Reference numeral 1 denotes a gargling device body, and the upper portion thereof is provided with a spouting nozzle 2 and a saucer 4 for collecting the gargling liquid mixture 3 discharged from the spouting nozzle 2. Inside the main body 1, a water supply pipe 5 connected to the jet nozzle 2 and installed vertically is formed, with a mixing pipe 6, a solenoid valve 7, a pressure reducing valve 8, and a filter 9 disposed in the middle. The lower end extension of the pipe 5 is connected to the water supply.

A gargling liquid pipe 11 is connected to the mixing tube 6 for sucking up the gargling liquid L from a gargling liquid container 10 installed at the bottom of the main body 1.

A drain pipe 12 for discarding the used gargling mixture is connected to the bottom of the saucer 4.
One end is formed to extend to the outside of the main body 1. A start button 13 is located near the jet nozzle 2.
is provided, and by operating the start button 13, a micro switch 14 provided below is turned on and off.
The microswitch 14 itself contributes to opening and closing the solenoid valve 7. Further, a light emitting element 15 and a light receiving element 16 are provided between the jet nozzle 2 and the mixing tube 6 so as to face each other,
A control section (not shown) is provided inside the main body 1 for detecting light from the light emitting element 15 with the light receiving element 16, converting it into an electrical signal, and comparing it with a standard signal. Furthermore, an orifice 17 is provided at the connection between the mixing tube 6 and the gargling liquid pipe 11 to ensure stable dispensing of the gargling liquid L and to prevent backflow of the gargling liquid mixture to the pump 18 side. A pump 18 is provided for pumping up the gargling liquid L from the gargling container 10 through the gargling liquid pipe 11, and a rotary blade 19 of the pump 18 is connected to a motor 20 controlled by the control section. Next, to explain the block circuit diagram of FIG. 3, the light emitting element 15 and the light receiving element 16 are
is a concentration detection device consisting of; is a comparison device that compares the electrical signal from the concentration detection device with a standard signal; and is a control unit that controls the pumping speed of the pump 18 using the signal from the comparison device. , is a driving part of the pump 18,
is a standard signal generator that sends a standard signal to the comparison device.

In the gargle having the above configuration, the start button 13 is pressed down to turn on the micro switch 14, and at the same time the solenoid valve 7 is opened, the motor 20 is driven and the pump 18 is turned on.
The rotor blades 19 are rotated to feed the gargle liquid L into the mixing tube 6. and the filter 9,
It is mixed with the water that has passed through the pressure reducing valve 8 and the solenoid valve 7,
The gargling liquid mixture 3 is ejected from the ejection nozzle 2. At this time, the gargling liquid mixture 3 passes through the concentration detecting device, where the light emitted from the light emitting element 15 is partially absorbed, reflected, refracted, etc. by the gargling liquid mixture L.
Furthermore, the transmitted light is detected by the light receiving element 16 and compared with a standard signal by the comparison device, and the pumping speed of the pump 18 is adjusted based on the difference, so that the light having a constant mixing ratio is always detected. Supply gargle mixture 3. Since the absorption rate, reflectance, and refractive index of light change depending on the mixing ratio, it is sufficient to adjust the standard signal to the intensity of light that passes through a gargle mixture having an appropriate mixing ratio.

The orifice 17 serves to prevent the gargling liquid mixture 3 from flowing back into the gargling liquid pipe 11 and to stably pour out a small amount of the gargling liquid L. It is something.

As described above, the present invention provides a concentration detection device for detecting the concentration of the gargling liquid mixture in the water supply pipe between the mixing pipe and the jet nozzle, and also includes a concentration detection device in the gargling liquid pipe.
A pump is provided that adjusts the pumping speed of the gargle fluid under the control of the concentration detection device, and an orifice is interposed in the gargle fluid pipe between the pump and the mixing pipe, so that a stable mixing ratio can be maintained at all times. In addition to being able to supply a gargle mixture,
The orifice allows a small amount of gargling liquid to be poured out stably, and also prevents the gargling liquid mixture from flowing back to the pump side.
