[0001]

[Industrial applications]

 The present invention relates to a chemical container for a flush tank in which an appropriate amount of a chemical solution such as a deodorant and a cleaning agent is automatically flowed into and mixed with the running water in the flush tank for a toilet.

[0002]

[Prior Art]

 As this type, a chemical container for a flush tank is known that is suspended in the flush tank to mix the chemical solution in the container into water. In this case, it is necessary to flow out an appropriate amount of liquid medicine into the tank each time the toilet is used, and various structures have been conventionally provided. Japanese Utility Model Publication No. 62-27583 is one such example. In this publication, the cap of the container is provided with a floating stopper that discharges the water and moves up and down by a reservoir, and by the action of the floating stopper, an appropriate amount of chemical liquid is automatically poured every time the toilet is used and flows into the water. I made it possible. In addition, as a method of suspending in the flush tank using a floating plug, there are JP-B-61-8147 and JP-B-62-27582.

[0003]

[Problems to be solved by the device]

 The conventional device shown in the above example is quite satisfactory, but it is not without its drawbacks. For example, since the chemical container is hung in the flush tank, it is necessary to open the heavy lid of the tank when changing the container or replenishing the chemical solution, and the level of the running water in the flush tank changes depending on the mode. In terms of handling, it is necessary to adjust the hanging position of the drug container depending on the type of tank due to the operation of the floating stopper.

The present invention controls the outflow of chemicals by using hand-washing water that is discharged from the tap at the top of the flush tank and becomes flush water, so that the flushing is simple and easy to handle by simply placing it on the lid of the tank. To get the drug container in the tank.

[0005]

[Means for Solving the Problems]

 The chemical container of the flush tank of the present invention is a dish-like shape in which a vertical bearing cylinder 5 is formed at the center of the bottom wall 4, and a gap is provided between the flush tank 6 and the lid 7 on the top of the lid 7. A pedestal 1 installed and placed, and a body for tightly fitting the pedestal 1 therein, and for holding a chemical solution which is held upside down with an appropriate gap between the mouth top and the bottom wall 4 From the screw portion 9 provided inside the mouth / neck portion 8 of the container body 2 with a gap such that liquid does not normally flow through the container body 2 and a lid 7 that communicates the bearing cylinder 5 into the tank 6. It is composed of a screw pump 3 which hangs down at a portion of a water flow hole 10 and a rotating shaft 12 provided with a blade 11 at a lower portion thereof is vertically movably attached.

[0006]

[Action]

 In the above description, the screw portion 9 of the screw pump 3 is fitted in the mouth / neck portion 8 of the container body 2 through a narrow gap that does not allow the drug solution to flow in a normal state. The chemical solution of is not discharged downward.

[0007] Here, when the water in the flush tank 6 is flushed by operating an operating plug (not shown) after using the toilet, in conjunction with this operation, it flows down from the tap (not shown) above the lid 7 into the tank 6 and is stored. The water for hand-washing, which will be used as the wash water for the next use, is discharged.

This water flows down to the bottom (upper surface in FIG. 1) of the container body 2 of the medicine container, then flows around the container body 2 and the pedestal 1 and flows down to the upper surface of the lid 7, and then to the upper surface of the lid 7 and the receiving surface. It flows through the gap between the bottom surface of the base 1 and the water hole 10 into the tank 6.

Then, the hand-washing water flowing into the tank 6 hits the blades 11 and drives the screw portion 9 to rotate via the rotary shaft 12, so that the screw pump 3 is started and the chemical solution in the container body 2 is caused to flow through a narrow gap. Then, the screw portion 9 is forcibly forced through the lower water flow hole 8 into the tank 6 and discharged.

When the water for hand washing stops, the rotation of the blades 11 stops and the screw pump 3 stops, so that the delivery of the chemical liquid stops. Since the amount of hand-washing water released is approximately constant, the amount of chemical solution delivered is also approximately constant.

[0011]

【Example】

 An embodiment will be described below with reference to the drawings. The chemical container of the flush tank of the present invention is composed of a cradle 1, a chemical liquid container 2 and a screw pump 3.

The pedestal 1 is a dish-like shape in which the peripheral side of the bottom wall 4 is slanted and raised upward, and the legs 13 are put out from the four corners of the bottom raised bottom portion, and a vertical shape is formed at the center of the bottom wall 4. The bearing cylinder 5 is pierced through and a radial receiving plate 15 is projected inward from the four inner surfaces of the lower half of the peripheral wall 14 and is further positioned inside the peripheral wall 14 to hold the retaining cylinder 16 at the bottom wall. It stands from 4.

The pedestal 1 is mounted on the upper surface of the lid 7 of the flush tank 6 with the bearing cylinder 5 positioned at the center of the water flow hole 10 of the lid 7 by the foot 13. Therefore, a gap is formed by the foot 13 between the bottom surface of the pedestal 1 and the upper surface of the lid 7.

It should be noted that, even if several engaging pieces are vertically hung from the central portion of the lower surface of the bottom wall 4 in a split cylindrical shape, these engaging pieces are engaged with the edge of the water flow hole 10 for positioning. Good.

Since the body part of the drug solution container 2 can be fitted in the peripheral wall 14 of the pedestal 1 in a liquid-tight manner, the inner cylinder 17 is fitted and fixed in the mouth / neck part 8, and An engaging ridge is provided on the outer surface of the mouth of the portion 8, and an inward flange-shaped support plate 18 is fitted and fixed to the ridge of the mouth by using the engaging ridge, and the peripheral edge of the shoulder is the receiving plate. It is supported by 15, and the mouth / neck portion 8 is internally housed in a holding cylinder 16, and an appropriate gap is provided between the mouth and neck portion 8 and the bottom wall 4 so that the pedestal 1 is held in an inverted state.

An inward flange 19 is shortly projected at the lower end of the inner cylinder 17 (upper end in FIG. 1), and a groove 20 for radial flow of the chemical liquid is circumferentially scattered on the upper surface of the support plate 18. There are several articles.

As shown in FIG. 2, the screw pump 3 has a rotary shaft 12 having several blades 11 provided at the lower end in the hollow portion of a screw portion 9 in which a spiral portion is formed on the outer surface of a closed cylinder. It is shaped so that it can be fitted and fixed as much as possible, the screw part 9 is placed on the support plate 18 of the mouth and neck part 8 of the container body 2 and is housed inside the inner cylinder 17, and the rotary shaft 12 is passed through the bearing cylinder 5 and the running water below The blade 11 hangs down from the shaft core of the hole 10 and is attached so that the blade 11 at the lower end of the rotary shaft 12 can rotate in the water flow hole 8.

An outer surface of the rotating shaft 12 located on the bearing cylinder 5 has a peripheral groove, and the peripheral groove is supported by being engaged with an engaging groove on the inner surface of the bearing cylinder 5. Further, vertical grooves 21 are provided in the outer circumferential surface of the rotating shaft 12 in a circumferentially discrete manner so as to allow the chemical solution to flow down.

A gap between the upper corner of the screw portion 9 and the flange 19 of the inner cylinder 17 serves as a chemical liquid discharge portion, but this gap is a narrow gap that does not allow the chemical liquid to flow through under normal circumstances.

In this embodiment, since the clearance for discharging the chemical liquid between the screw portion 9 of the screw pump 3 and the flange 19 of the inner cylinder 17 is narrow, the chemical liquid does not always flow downward from the container body 2. .

However, when hand-washing water is discharged from a tap (not shown) by using a toilet, this hand-washing water flows down from the upper surface of the medicine container to the upper surface of the lid 7, and through the gap between the bottom surface of the pedestal 1 and the water outlet. Since the water flowing from 10 into the tank 6 hits the blade 11 in the water flow hole 10 and rotates the screw portion 9 via the rotating shaft 12, the screw pump 3 is started and the chemical liquid in the container body 2 is discharged. Since the chemical liquid is forcibly delivered downward through the gap between the screw portion 9 and the inner cylinder 17, the chemical liquid is delivered into the tank 6 from the groove 20 on the upper surface of the support plate 18 through the groove 21 on the outer surface of the rotary shaft 12.

When the hand washing water stops, the rotation of the blades 11 stops and the screw pump 3 stops, so that the delivery of the chemical solution stops.

In the above-described embodiment, at the time of distribution, the rotating shaft 12 of the screw pump 3 and the blade 11 are integrally removed from the screw portion 9, and a separate cap 22 is attached to the outer surface of the mouth / neck portion 8 of the container body 2 as shown in FIG. Screw together.

[0024]

[Effect of the device]

 As described above, since the chemical container of the flush tank of the present invention is configured to operate the screw pump 3 for delivering the chemical solution by using hand-washing water, it can be placed on the upper surface of the lid 7 of the tank 6, and its handling Is extremely simple, and on top of that, there is an advantage that a suspending component for suspending in the tank 6 is unnecessary.

Further, since the liquid medicine is delivered by the screw pump 3 which is operated by the falling hand-washing water, not by the floating stopper which operates by the displacement of the liquid level, the liquid delivery is reliable, stable and highly reliable.
