Definitions

• This invention concerns a metering dispenser of treatment liquid in water closets, and more particularly this invention concerns a device for the delivery of a determined amount of a bacteriostatic liquid agent at the time of flushing in such a way as to leave, after each operation, a bacteriologically "clean" unit for - the next user.
• the device according to the invention can advantageously be combined with a device delivering environmental deodorant by means of indirect positive activation with each operation.
• a device is foreseen associated with a dynamic liquid injector in a water-flush falling column associated with a valve device which allows the withdrawal, from time to time, of an amount of water precisely metered at the time of flushing by putting the said amount of water in communication with a liquid-liquid exchanger associated with a feed supplier from a container containing a bacteriostatic liquid or other treatment liquid.
• the container, valve device and bottle of bacteriostatic liquid or other treatment liquid is designed in such a way that the movement of water into if induces an aspiration action such that a supplier of environmental deodorant is activated, the deodorant being impregnated onto felt or similar material able to contain a volatile liquid or solid.
• a dispensing device for administering a predetermined amount of treatment liquid into water closets, comprising a casing within which is a container-dispenser, co-operating with a chamber containing a float-operated valve, the container-dispenser being adapted to dispense a pre-determined amount of treatment liquid into the chamber when the chamber is flooded by a flow of flushing water, the a mount of flushing water being controlled by the float operated valve.
• a hydrodynamic unit may be provided in the flushing water pipe which is adapted to supply flooding to the said chambers.
• a method for administering a liquid to water closets which comprises dispensing the liquid from a device which consists of a casing within which is a treatment-liquid dispenser which co-operates with a chamber containing a float operated valve, the components of the device being arranged such that, at the beginning of a flushing cycle, flushing water floods the chamber to a level determined by the position of the float operated valve, the influx of flooding water releasing a predetermined amount of the treatment liquid from the dispenser into the chamber, which is expelled from the device along with the flushing water into the water closet, at the end of the flushing cycle.
• the chamber may be partitioned into a first and a second chamber, said first chamber containing the float -operated valve, and said second chamber co-operating with the container-dispenser, the arrangement of the chambers being such that flooding water may pass freely between the two chambers.
• a method for administering a metered amount of deodorant into the atmosphere which comprises a dispensing device as hereinbefore defined, an aperture fitted to the casing of the device, and an enviromental deodorant dispenser impregnated with a volatile liquid or solid, the components being arranged such that during a flushing cycle, air is displaced through said aperture and a metered amount of deodorant is expelled into the atmosphere.
• Figures 1,2 and 3 show schematically in perspective, lateral and plan views respectively, the design of a device according to this invention.
• Figure 4 shows an even more schematic view of the device according to the Invention in the resting position.
• Figure 5 shows, in succession to Figure 4, a view of the device according to the invention in the refilling phase during a flushing operation.
• Figure 6 shows a view a ⁇ alagous to that of Figure 5 in the phase of inflow of bacteriostatic liquid or other treatment liquid
• FIG 7 shows, similarly to Figure 6, the discharge phase of the device according to the invention.
• the device comprises a casing 1 containing a tank 2 of treatment liquid, particularly a bacteriostatic liquid, an aspiration chamber 3 the flooding of which is controlled by a valve 4 associated with a float 5, and an exchange or dilution chamber 6 fed from tank 2 via a metering dispenser valve- 7.
• the side of valve 4 turned towards the outside is connected by pipe 8 to the water flush falling column 9, which is forced through conduit 8 by means of a hydrodynamic dispenser device symbolized by the element 10.
• a dispenser of enviromental deodorant 11 of the type comprising a felt unit or other similar material which dispenses a deodorant in accordance with the aspiration action induced by the displacement of liquid in chambers 3 and 6.
• valve 4 in the resting position the valve 4 is disposed against the seal present at the end of pipe 8, and the device is ready for operation.
• the tube 9 With a flushing operation the tube 9 is traversed by a column of moving water, part of which is captured by element 10 of the hydrodynamic dispenser and is sent through pipe 8 so as to refill chamber 3 and raise the float 5 until the valve 4 blocks the subsequent flow of water by sealing against seating 4a.
• the water which reaches the aspiration chamber 3 passes through a passage (not illustrated) to reach the exchange or dilution chamber 6.
• Figure 7 is shown the end of the dispensing operation.
• the predominance of the water column traversing pipe 9 is in the final phase and there is no longer a hydraulic counter-pressure forcing valve 4 against seating 4a 1 and prohibiting the passage of water into chamber 3. Consequently, the predominance of the added treatment of bacteriostatic agent liquid present in chambers 3 and 6 prevails over the thrust of water in tube 9 and reaches the water closet unit.
• the solution according to this invention is particularly advantageous in that a calibrated dispensation of treatment agent, particularly a bacteriostatic agent, is produced without the use of external motor force save the almost gratuitous force supplied by the column of flushing water.
• container 2 can suitably be produced with a capacity of 600 ml and with a dispensation through metering valve 7 of 0.5 ml per flush, this content will suffice for 1200 flushes.
• an operational time of 76 days or 9.2 weeks can be attained. With a mean of 20 flushes per day, the operational time will be about 8.5 weeks.
