Definitions

  • the invention relates to a mechanical dosing device for cisterns from Wcs in accordance with the preamble of claim 1.
  • odor formation is e.g. countered by inserting fragrance stones or fragrance packs in a perforated container arranged in the toilet bowl. This method is partly unsanitary and partly impractical and is not a satisfactory solution to the problem. Furthermore, odor formation is counteracted by spraying fragrances. This solution results in considerable environmental problems, since the disposal of the spray cans is extremely polluting.
  • a dosing insert for additives in toilets water boxes with a reservoir holding the additive is known.
  • the storage container receiving the liquid additive has a lower outlet opening, to which a metering valve insert is attached, which comprises an inlet valve, an outlet valve and a metering chamber located therebetween and a valve closing body.
  • a float mounted vertically on the dosing insert is connected to the valve closing body.
  • a metering insert proposed by this utility model has a number of significant shortcomings which prevent the metering insert from being suitable for practical use. So z. B. the height of the known metering device due to the proposed construction so large that the placement in conventional cisterns is difficult.
  • the upper central inlet opening must be kept very small so that the metering agent inlet is limited; This has the consequence that it is very difficult for the air enclosed in the dosing chamber before filling to escape upward against the dosing agent flowing in, since the cross section of the central inlet opening is extremely small.
  • the metering is therefore in such a metering device
  • the cross-section between the metering chamber and the outlet opening into the cistern space is also very small, since the guide rod for receiving the float should essentially fill the bore in order to achieve perfect rod guidance. To achieve this, little play is required; this slight play is also necessary so that the dosing agent can flow from the dosing chamber past the linkage into the cistern.
  • this metering device is designed so that when the cistern is full, the inlet valve is closed and the outlet valve is open, and conversely, when the cistern is empty, the inlet valve is open and the outlet valve is closed.
  • the function of the float is limited to the pure buoyancy function.
  • the object of the invention is to provide a solution for odor removal in toilets, which meets the needs of practice, is hygienic to use, does not pollute the environment, is easy to handle, namely is triggered together with the flushing process, and is constructed in this way that the buoyancy body is also effective as a sealing device on the underside of the metering device.
  • liquid-soluble dosing agent is added to the water supply in the cistern together with the flushing process.
  • This dosing agent can be, for example, a fragrance and / or a cleaning agent and / or a disinfectant that gets into the toilet bowl with the rinsing water and thereby exerts the desired effect.
  • the container that holds the dosing agent is inserted into the water reservoir of the cistern.
  • the container is refilled with dosing agent either via a line or hose connection between the outside of the cistern and the inside of the container, so that filling from the outside is safe is set, or by removing the cistern lid and container lid by immediately filling the dosing agent.
  • the bottom of the container has an opening which is opened and then closed again for the metered delivery of the dosing agent into the water reservoir of the cistern.
  • the bottom opening of the container is assigned a concentric chamber down which a closure element, for. B. in the form of a bolt with a head, and serves as a buffer for the dosing agent, as long as the discharge opening in the cistern is closed.
  • the dosing agent feed from the dosing agent container takes place in the radial direction through openings in the peripheral wall of the feed device.
  • two concentric chambers are provided, the radially outer chamber being filled with water from the cistern and the open underside of both chambers being closed by the buoyancy device as long as the cistern is filled with water.
  • the buoyancy device (float) is designed so that it has an upper, sealing closure surface which, when the cistern is full, is pressed against the underside of the chamber or the two chambers, so that the chambers are closed from below, while the closure device in the upper Area, namely where the dosing agent can enter the inner chamber, is open and through these openings the inner chamber is filled with dosing agent.
  • the drive for the buoyancy device is missing, so that the closure device in the lower region releases the underside of the two chambers, blocks the inflow of dosing agent into the chamber and the inner chamber shows its filling quantity of dosing agent on its underside can flow radially outward where the dosing agent is premixed with the water in the outer chamber.
  • the closure body which controls the metering agent inlet, has an O-ring seal which is formed by an annular recess of the cross-section which is partially circular in cross section Head part of the closure device is received, and which cooperates with an annular receptacle of the chamber wall receiving the open annular region of the O-ring and sealingly receives the O-ring in the closed position.
  • the metering agent is thus fed from the container into the metering chamber by lowering the cylinder and positioning the O-ring seal.
  • This inflow is adjusted and can be controlled in such a way that the inflow opening is made changeable or adjustable in cross-section by assigning a second annular wall, which is designed to be movable radially or axially to the first annular wall, to the annular wall receiving the inflow openings, such that that the cross section of the openings is changed by relative movement of one relative to the other ring wall.
  • the cylindrical locking pin has a bottom with a downwardly directed guide bolt with an internal thread, into which a bolt with an external thread can be screwed, which is firmly connected to a spherical cap-shaped buoyancy body.
  • the outer cylindrical chamber surrounds the metering chamber in the radial direction. Like the dosing chamber, it is open at the bottom and is closed in a sealing manner by the buoyancy body, as long as the dosing agent closure supplying the dosing agent is open.
  • the radially outer peripheral wall of the outer chamber has openings which are offset approximately uniformly in the circumferential direction and through which water flows from the cistern into the chamber. Since this chamber is open at the bottom, the water column in the chamber rests on the upper side of the buoyancy device facing and sealing the chamber. If the water level in the cistern falls, the water column in the outer chamber pushes the buoyancy device down from the sealing position and supports the sinking movement of the float.
