Automatic dosing device for active substances

It is known that by adding active substances to a solvent, various properties can be achieved Solvent can change. For example, adding electrolyte to water increases the conductivity of the water changed, or it is enabled by adding active cleaning substance to the water to perform cleaning work.

In any case, it is important to adhere to a previously determined dosage in order to achieve the desired effect.

In the case of frequently recurring dosing processes, one works with dosing devices, which are used with each dosing process add the same amount of active ingredient to a given amount of solvent.

The dosing of liquids is very easy, as the amount of active substance can be determined through a simple measuring vessel can be set.

In the case of solid active substances, a liquid active substance concentrate is therefore often first produced and then this dosed by means of a dosing device for liquids.

One application of this principle are the so-called toilet water tank cartridges. These essentially exist from a container which is filled with solidified active cleaning substance or a mixture thereof and is hung in the flush water reservoir of a toilet. The water penetrates this container and dissolves the active cleaning substance contained therein. Due to the natural flow in the toilet's flush water reservoir Active cleaning substance gets into the water held ready for the subsequent rinse. This will result in the Flushing process the toilet bowl is flushed with a cleaning solution, which removes any existing soiling can be removed and the emergence of new soiling is prevented.

However, the devices that have become known so far have '|

all have the disadvantage that the part of the rinse water f

Active substance is given, which the toilet bowl only flows through and does not remain in the same after the flushing process has ended.

The invention is based on the object to provide a metering device which is only a fraction of the applied rinse water active substance metered.

The object is achieved in that an active substance - (4) in a laterally closed container (l) arranged and this is equipped with a float (2) and a tilting device (j5). (Fig. L)

The container (1) is usually designed as an upright column, whose base can assume any geometric figure. The container can also be designed as a truncated cone or as a truncated pyramid, the smaller area in each case Application facing down.

The float (2) and the container (1) can be a unit which is made in one operation from the same material ^ Fi ^0- . 1 ^ · The float will preferably be placed above the center of gravity of the container, as this will best perform its task. In another embodiment (FIG. 2) of the proposed metering device, the float and container consist of two parts which are produced in two separate operations. Various embodiments are also possible here. In one embodiment, one or more floats are attached to the outer wall of the container. They can be of any shape.

In another embodiment (Fig. 3) is the Float housed in the container and is located in the cement or above the active substance. In a Another embodiment (Fig. 4), the float is placed on the container, either by the shape of the float or the type of attachment, the upper opening of the container is not completely closed will. In this embodiment, a plurality of openings in the container can also be present on its upper side

being. ··· / - '

The tilting device (3) consists essentially of a holder, which preferably holds the container connects on the lower side with the edge of the cistern. This holder consists in one embodiment (Fig. L) from a fixed rod (5) * which has an eyelet (6) on the underside of the container (l) is connected. There is free rotation between the rod and the eyelet. The other end of the rod is with firmly connected to the wall (8) of the cistern. In a further embodiment (Pig 5) there is the tilting device from a movable belt (7) or a thread, which is attached to the lower side of the container is connected and the other end is firmly connected to the wall (8) of the flush water tank.

The following describes the mode of operation of the automatic metering device for active substances in cisterns to be discribed :

After emptying the cistern, the dosing device is lying on the floor (Fig. 6) the cistern (8) or hanging on the tilting device (Fig. 7) the active substance concentrate has run out. As the water level rises (9), the container is filled with water in a horizontal position (Fig. 8) The buoyancy force of the swimmer raises the tank when the water level continues to rise and thereby prevents the water in the container (lo), which is meanwhile active substance has dissolved, enters the rinse water surrounding the container (Fig. 9). If the cistern is now emptied, so the water level sinks and with it the container. With a previously freely selectable water level, now the container prevented from further sinking by the tilting device, whereby it was due to the lack of buoyancy of the float moves out of the vertical position and tilts if the water level continues to fall. Concentrated active substance solution is added to the last portion of the rinsing water. After complete expiration of the rinsing water, the container is then in the position shown in Figure (6) or (7).
