Description

[Detailed explanation of the invention] <Industrial field of application> This invention is suitable for use in toilet flush tanks, etc.
This invention relates to a cleaning and supplying device for an aquarium that is intermittently sprayed with water and filled with water after being sprayed so as to be filled with water.

<Conventional technology> As a conventional supply device of this kind, there is a
There are products disclosed in Japanese Patent Application Laid-open No. 32265 and Japanese Patent Application Laid-open No. 59-76338, but they all have a complicated structure and have the disadvantage of increasing mold and equipment costs during manufacturing, and are not disposable. This type of feeding device, which has a large number of parts, has a problem in terms of cost.

For this reason, a supply device has recently been proposed in which a hollow cylindrical container is simply provided with a small hole through which the cleaning solution flows out.

A cleaning liquid supply device using such a cylindrical container is
When the aquarium is filled with water, water enters the container through the small holes and soaks and dissolves solid substances containing water-soluble detergents, such as surfactants, pigments, fragrances, and bleaching agents,
When water is discharged from the aquarium, the cleaning liquid in which the detergent in the container is dissolved and diluted flows out into the aquarium through the small holes.

<Problems to be solved by the invention> However, in this type of supply device, it is required that the cleaning liquid has a certain dilution concentration and that the cleaning liquid does not remain in the water tank. A configuration in which only a small hole is opened in a cylindrical container as shown has a practical problem.

First, the supply device shown in FIG. 6A has a structure in which a small hole 2 is formed protruding from the upper part of a cylindrical container 1 and a cleaning agent 3 is accommodated inside. ₁ descends to the bottom of the device when discharging water, the liquid level _L2 of the cleaning liquid 4 in the container 1 only descends to the lower end of the small hole 2, as shown by the chain line.
It is possible to stop the outflow of the cleaning liquid 4 before the water in the aquarium is released and effectively prevent the cleaning liquid 4 from remaining in the aquarium, but on the other hand, it has the disadvantage that the amount of cleaning liquid that flows out is small. Since the cleaning liquid 4 flowing out is limited to the upper part of the container 1, there is a problem that the dilution concentration of the cleaning agent is low.

Next, the feeding device shown in FIG. 6B has a structure in which a small hole 5 is protruded near the center of the body of the cylindrical container 1.
In this configuration, since the liquid level L2 of the cleaning liquid 4 falls to the center of the container, the dilution concentration of the shallow cleaning agent is higher than that in the supply device shown in FIG. A, but it is still insufficient.

However, with this type of device, although the outflow time of the cleaning liquid 4 is longer, the outflow of the cleaning liquid 4 is stopped before the stopper of the water tank works and the water discharge is stopped, and it effectively prevents the cleaning liquid 4 from remaining in the water tank. I can do it.

The feeding device shown in FIG.
In this case, the outflow amount of the cleaning liquid 4 can be increased and the dilution concentration can be made uniform.
Because the outflow time becomes longer, the cleaning liquid 4 continues to flow out even after the water tank stopper works and the water discharge stops.
There is a problem in that the amount of cleaning liquid remaining in the water tank increases, and parts in the tank are adversely affected by the chemicals.

<Means for solving the problems> As shown in FIGS. 1 and 2, the present supply device has the following features:
A drain mechanism 20 is attached to the body 11 of a cylindrical container 10 with a bottom, and a water-soluble solid detergent 30 is housed inside.

The liquid drainage mechanism 20 includes, for example, the solid detergent 30.
an upper small hole 21 transparently provided in the upper part of the container body 11 so as to open upward; and a lower small hole 22 transparently provided in the lower part of the body 11 so as to open near the bottom surface of the container 10, for example; It is equipped with a tube body 23 that allows the upper and lower small holes 21 and 22 to communicate with each other, and an outlet 24 provided in the center of this tube body 23, and this liquid drainage mechanism 20 solves the above problem. This is what we are trying to solve.

<Function> As shown in FIG. 3A, in the present supply device, when the water tank is full of water, the cylindrical container 10 is filled with water and the detergent 3 is filled with water.
0 and then when the aquarium is watered, the third
As shown in FIG. B, the cleaning liquid 40 containing the diluted detergent flows out from the outlet 24 of the drainage mechanism 20 due to the ventilate effect caused by the movement of water in the water tank.

The cleaning liquid 40 flowing out in this way is
However, when the water tank is filled with water again, the container 10 is filled with water that flows backward from the outflow port 24, and as shown in FIG.
The state shown in is reached.

This backflow of water is guided into the container through the two upper and lower small holes 21 and 22 through the pipe body 23.
At this point, a vortex is created in the container and the solid detergent 30 inside is washed away by the vortex.

<Example> In FIGS. 1 and 2, 10 is a cylindrical container with a bottom, a drain mechanism 20 is provided on the outside of the body 11, and a water-soluble solid detergent 30 is stored inside. be done.

The liquid drainage mechanism 20 has an upper small hole 21 transparently provided in the upper part of the body 11 so as to open above the solid detergent 30, and an upper hole 21 that opens at a position close to the bottom surface of the container 10. A tube 23 provided outside the body 11 so as to communicate the lower small hole 22 transparently provided in the lower part of the body 11 with the two small holes 21 and 22, and the center of this tube 23. The outlet 24 is provided with an outlet 24 projecting from the bottom.

The upper surface of the container 10 is covered by a lid 12, etc., and the lid 12 has a ventilation hole 13 transparent therethrough, and the outer surface of the container 10 is provided with mounting means, for example, a hanging tool 14. The container 10 is suspended in a water tank (not shown).

Therefore, when the water level of the aquarium rises, water flows backward into the container 10 from the outlet 24, while when the water level of the aquarium falls, the cleaning liquid 40 in which the detergent 30 is dissolved and diluted flows out from the container. It's going to happen.

In the above, the container 10 is not necessarily one
For example, as shown in Figure 4,
A plurality of containers 10, 10 may be combined so that the containers share one outlet 24, thereby increasing the types and amounts of chemicals used.

The tube body 23 is the container 10 in the embodiment shown in FIG.
However, the configuration of this tubular body 23 is arbitrary.For example, as shown in FIG.
1 may be formed separately from the tube body 2. In this case, the tube body 2
The tube body 23 may be made by bonding the outer tube wall portion 231 of No. 3 to the container body 11.

The upper small hole 21 may be provided so as to take out the low-concentration cleaning liquid. Therefore, if the space above the detergent 30 is long, such as when the detergent 30 is housed in a long and narrow container, it should be located close to the upper end of the container. There is no need to provide one.

Although a small-sized detergent 30 is used in the embodiment, a larger one may be used depending on the case. It will be located higher than 21.

The lower small hole 22 may be opened at the bottom of the container so that the high concentration cleaning liquid can be taken out, and therefore may be opened on the same plane as the bottom surface, or alternatively, as shown in the drawings of the embodiment. The opening may be made at a location slightly higher than the bottom surface.

In the container 10, as in the embodiment, if the water surface L1 does not reach above the container 10, the lid 12 may be provided with a ventilation hole 13; It is configured so that it opens at

<Effects of the invention> Since the device of the present invention is as described above, the vortex generated when the water in the aquarium flows back into the container 10 agitates the inside of the container and promotes the dissolution of the detergent 30. is taken out from the upper and lower parts of the container 10 at the time of outflow, there is an advantage that the bottom concentration cleaning liquid in the upper part and the high concentration cleaning liquid in the lower part are mixed to form a cleaning liquid having an appropriate concentration. Since the cleaning liquid 40 concentrates from the small holes 21 and 22 in the upper and lower two places, the amount of cleaning liquid 40 flowing out is large. Therefore, when the water level L1 falls below the outlet 24, the liquid level L2 of the cleaning liquid 40 reaches the outlet. Since the cleaning liquid 40 is lowered to a height of 24, it is possible to effectively prevent the cleaning liquid 40 from flowing out after water is discharged.
