First Embodiment
FIG. 1 is an explanatory view of the urine sprinkling prevention device 1 according to the first embodiment of the present invention.

The urine sprinkling prevention device 1 has a device main body 19 and a fixing device 25 for liquid transport.
The apparatus main body 19 and the liquid transfer fixing tool 25 are connected by the fixed tool side first liquid transfer pipe 23 and the fixed tool side second liquid transfer pipe 24.
The liquid transfer fixing tool 25 passes the fixed tool side first liquid transfer pipe 23 and the fixed tool side second liquid transfer pipe 24 in a penetrating state.
Then, the liquid transfer fixing tool 25 plays a role of releasing each liquid from the fixed tool side first liquid transfer pipe 23 and the fixed tool side second liquid transfer pipe 24 in a predetermined direction (position) in the toilet bowl B. Have.
That is, the liquid transfer fixing device 25 is a direction and position fixing device.

The apparatus main body 19 has a first liquid container 2 for the first liquid 102 and a second liquid container 3 for the second liquid 103.
The first liquid container 2 has a first container attachment 11, and the second liquid container 3 has a second container attachment 12.
The first container attachment 11 is made so that the first liquid container 2 can be replaced.
Similarly, the second container attachment 12 is made so that the second liquid container 3 can be replaced.
A container-side first liquid transfer pipe 13 extends from the first container attachment 11.
Similarly, a container side second liquid transfer pipe 14 extends from the second container attachment 12.

A valve 15 is disposed between the container side first liquid transfer pipe 13 and the fixture side first liquid transfer pipe 23.
Similarly, a valve 15 is disposed between the container side second liquid transfer pipe 14 and the fixture side second liquid transfer pipe 24.
The valve 15 is controlled by the controller 16 in terms of open / close / open / close degree / open / close time.
In this embodiment, the valve 15 can simultaneously control the first liquid 102 and the second liquid 103 with one valve.
However, it is naturally possible to separately provide separate valves 15 respectively.

The first liquid container 2 and the second liquid container 3 are formed so as to be able to be charged so that each new container can be removed, for example, when the contained liquid is exhausted.
At this time, it is more appropriate to form a package 4 in which the first liquid container 2 and the second liquid container 3 can be charged together at the same timing.
The shapes of the first container attachment 11 and the second container attachment 12, the shape of the package 4, the shape of the portion for storing the package 4 and the like are special shapes, and the first liquid container 2 and the second liquid container 3 It is more appropriate to prevent reverse mounting. The fact that the first liquid container 2 and the second liquid container 3 can be exchanged in the same operation as the package 4 also contributes to this.
By making such replacement possible, the user can easily perform maintenance.

The control unit 16 is formed to be able to communicate with the wireless slave device 17 wirelessly. Further, a valve control unit 18 is formed by the control unit 16 and the valve 15.
The wireless slave device 17 detects a person or detects the opening and closing of a door, and wirelessly notifies the control unit 16 of the information.
In response thereto, the control unit 16 closes the valve 15 after opening the valve 15 for a predetermined time.
During this time, the first liquid 102 and the second liquid 103 are discharged toward a predetermined position in the toilet bowl B.
Note that the opening by the valve control unit 18 may be based on the user pressing a button or the like to the wireless slave device 17 or the control unit 16. Anything else may be used.

By forming in this manner, it is possible to form bubbles before the user actually urines.

The first liquid 102 is a liquid containing at least baking soda.
The second liquid 103 is a liquid containing at least citric acid. Furthermore, it is preferable that the second liquid 103 contains a surfactant.
Note that the surfactant is not essential for the second liquid 103, and it is also possible to prepare a container or the like separately and send it out into the toilet bowl B.
Here, the reason for adding the surfactant to the second liquid 103 is mainly the simplification of the apparatus such as the saving of the container.
However, surfactant can not be introduced into the first liquid. The reason is that the baking soda and the surfactant react with each other.

When baking soda and citric acid are mixed, a gas is generated. This is the mechanism that makes bubbles.
Also, in that state, if a surfactant is present, the foam lasts longer.

When such bubbles cover the surface of the water of the toilet bowl B, even if urine is produced by a man or the like standing, urine splashing can be reduced.
In addition, even if there is no splashing during urine discharge, it is possible to reduce splashing when the water in the toilet bowl B flows at the time of flushing.
Further, although not shown, a power on / off button is disposed in the device main body 19.
Furthermore, it goes without saying that the urine splash prevention device 1 can be driven manually.

FIG. 2 is an explanatory view of the arrangement of the urine splash prevention device 1 and the like.

As shown in FIG. 2, the liquid transfer fixing device 25 of the urine sprinkling prevention device 1 is fixed to the upper surface of the toilet bowl. In this figure, although it is fixed to the center of the back of the toilet bowl B, you may be fixed to the place other than this.
Further, the device main body 19 is fixed to the lateral part of the toilet seat or the like. Of course, it is also possible to install in other parts.
The fixing device-side first liquid transfer pipe 23 and the fixing device-side second liquid transfer pipe 24 connect the apparatus main body 19 and the liquid transfer fixing tool 25.

FIG. 3 is an explanatory view of a positional relationship between the apparatus main body 19 and the wireless slave device 17 and the like.

As shown in FIG. 3, the wireless slave device 17 is fixed at a predetermined position on the door D side or a position that the user can reach.
Then, upon detecting that the user m has entered the room, that the door D has been opened, and the like, the urine splash prevention device 1 creates a bubble.

FIG. 4 is an explanatory view of a fixing device 25 for liquid transfer.

As shown in FIG. 4, the lower surface of the liquid transfer fixing tool 25 is flat. It is fixed to the upper surface of the toilet bowl B with an adhesive such as double-sided tape on this portion.
On the other hand, the upper surface is formed in a shape that changes smoothly with the upper surface of the toilet bowl B.
This is because the urine and the like adhere to the toilet seat so that it does not remain when the urine and the like are wiped off. This is very significant not only in terms of appearance but also in practical hygiene. On the contrary, if it does not have a smooth shape, the residue on the part is extremely harmful to hygiene.
Note that one example of the shape of the liquid transfer fixing tool 25 is the shape shown in FIG. 4 and any shape that is smooth with respect to the upper surface of the toilet seat is a modification of the present embodiment.

Other Embodiments
FIG. 5 is an explanatory view of a modified example of the urine splash prevention device 1.

It is also possible to use another surfactant as shown in FIG.
It is also possible to put, for example, a sterilizing / aroma / detergent liquid into a third tank while putting a surfactant in the second liquid 103.
Of course, the first liquid 102 or the second liquid 103 can also contain germicidal, aroma and detergent components.

FIG. 6 is another embodiment of how to mix the first liquid 102 and the second liquid 103.

As in the first embodiment, the first liquid 102 and the second liquid 103 may not be mixed in the toilet bowl B, but may be mixed before being discharged to the toilet bowl B as shown in FIG.

FIG. 7 shows the experimental results of the ratio of baking soda and citric acid.

The inventors consider that baking soda and citric acid are the best for foaming.
Among them, Patent Document 1 discloses the use of the two, but since there is no description about an appropriate amount, experiments were conducted by adjusting the amount.
Then, the generation rate and amount of bubbles were measured by visual observation.
The amount of the foaming agent 101 used in the experiment was 20 g in total of sodium bicarbonate and citric acid.
In addition, in the experiment of FIG. 7 and the experiment of FIG.

It can be seen from this experiment that when the weight percent is 30% to 55% of baking soda and the rest is citric acid, appropriate foam is generated.
Furthermore, more preferably, it can be seen that the optimum foam is generated when the weight percentage is 40% to 45% of sodium bicarbonate and the remainder is citric acid.

FIG. 8 is an experimental result of the ratio of surfactant.

Next, experiments were conducted on the amount of surfactant that is appropriate to add to further maintain the foam.
Although this surfactant is also described in Patent Document 1, there is no description of an appropriate amount and type of surfactant.
The experiment was conducted for the appropriate amount of surfactant. The result is shown in FIG.
The amounts of baking soda and citric acid were found to be optimal according to the results of the experiment in FIG. 7, in the range of 40% to 45% by weight of baking soda and the remaining citric acid, sodium bicarbonate: 3 The ratio of citric acid to 4 is 4 (sodium bicarbonate: about 42.85%, citric acid: about 57.15%).
Currently, the inventor considers that the ratio of citric acid: 4 to baking soda: 3 is the optimum value.
Furthermore, a surfactant is added to the foaming component made into this ratio, and it is experimented by setting it as 20 g in the whole which added both.
The surfactant used was an anionic surfactant.
In addition, about the duration of foam, it confirmed by visual observation.

From FIG. 8, it was found that when the weight of baking soda + citric acid is 75% to 95%, the surfactant maintains the foam to a practicable level when the rest is used as the surfactant. The
Furthermore, it was found that the optimum value is when the weight of baking soda + citric acid is set to 80% to 90%, and the rest is used as a surfactant.
Finally, the inventor considers that sodium bicarbonate: citric acid: surfactant = 3: 4: 1 is the optimal blending ratio, and the final product is to be manufactured at this ratio.

Based on this result, experiments were conducted with sodium bicarbonate: citric acid: surfactant = 3: 4: 1 and surfactants other than anions such as amphoteric surfactants and nonionic surfactants.
In any case, it was found that the same effect was obtained (it is omitted because it is almost the same result as FIG. 8).
In the urine splash prevention device 1 of the present invention, since it is used as a liquid, it is dissolved in water or the like so as to have these proportions.

Another Embodiment
Furthermore, the first liquid 102 and the second liquid 103 are not limited to sodium bicarbonate and citric acid (further, surfactants). That is, it may be anything as long as it can produce the foam component formed on the water in the toilet bowl.
Furthermore, in some cases, such as the first liquid 102 and the second liquid 103, it is not necessary to chemically boil the two liquids, providing only a single liquid, water or air, or compression. It is also possible to make foam by foaming from the state (principle like hair setting mousse).
