Description

[Detailed Description of the Invention] [Industrial Application Field] The industrial application field of the present invention is a flush tank capable of supplying a predetermined amount of a chemical solution such as an air freshener (including disinfectants, etc.) to the toilet side. This is the field of chemical liquid supply equipment.

[Prior Art] Conventionally, the following methods have been known for supplying chemicals such as aromatics, deodorants, antifouling agents, and disinfectants into a toilet bowl. The first method is to submerge a container containing a solid drug in a flush tank, dilute and diffuse the drug from its surface into the water, and let this diluted water flow down when flushing, leaving a portion of it in the toilet bowl. It is a storage method. The second type is a system in which a basket-shaped storage container for solid medicine is placed at a flushing position in the toilet bowl, the medicine is dispersed in the toilet bowl by running water, and a portion of the medicine is left behind in the toilet bowl.

[Problems to be Solved by the Invention] However, the first and second prior art techniques have the following common drawbacks. In other words, the medicine is diluted and dispersed in running water, but most of it flows away with the water that washes away the filth, and only a part of it remains in the toilet bowl.
Most drugs were wasted as they were consumed without exhibiting their initial effects.

[Means for Solving the Problems] The chemical solution supply device for a water washing tank according to the present invention has been made in order to improve the above-mentioned drawbacks, and is designed to accommodate chemicals such as aromatic liquid, deodorizing liquid, sterilizing liquid, etc. A chemical solution tank, a cylindrical body disposed within a washing tank main body, connected to the chemical solution tank via a connecting means, and having an open lower end, and a valve that can be freely opened and closed and disposed within a range from the chemical solution tank to the cylindrical body. , one end communicates with the chemical solution tank, and the other end is configured to include a supply means directly or indirectly led to the toilet side,
The feature is that when water is stored in the tank body, the chemical solution is supplied to the toilet side using air pressure.

[Function] When such a configuration is adopted, the chemical solution can be supplied to the toilet bowl after the waste in the toilet bowl has been flushed away by the running water from the flush tank, that is, when the flush tank is in the process of storing water. Can prevent wear and tear. In addition, the air pressure is increased as the water level rises due to water storage, and the medicinal solution is pumped using this air pressure, which simplifies the mechanical configuration of the device.

As a result, the chemical liquid is pushed and extruded from the lower end of the cylinder 23 into the tube 27 . This chemical solution is supplied into the toilet after use through the tube 27. During the next use, the water level will drop and the pressure inside the cylinder will become negative, but the valve 26 at the upper end of the cylinder 25 will close, so no chemical liquid will be sucked from the chemical liquid tank 21.

Thereafter, the same operation is repeated, and each time the toilet is used, the medicinal solution is supplied to the toilet after use.

[Effects of the Invention] As is clear from the above description, according to the present invention, after the waste in the toilet bowl is flushed away by running water from the flush tank, that is, when the flush tank is in the process of storing water, Since the medicinal solution can be supplied to the toilet bowl, the entire amount of medicinal solution can be used effectively and unnecessary wear and tear can be prevented.
In addition, because the chemical solution in the chemical tank is pushed out by air pressure by utilizing the rise in the water level within the tank body, and the chemical solution is supplied to the toilet side after use, there is no need for a complicated device mechanism, and the cost is low. A chemical solution supply device can be obtained.

Furthermore, when the chemical liquid tank is mounted outside the tank body, it is easy to replace the chemical liquid tank, and the remaining amount of the chemical liquid can be known reliably, so that the time for replacement will not be missed.
