Description

The invention relates to the field of dosing of substances, including for dosing of active liquid substances in the tank for the toilet. The internal surfaces of the toilet during operation are subject to contamination. Flushing with water does not ensure complete removal of its difficult to wash off residues.

Therefore, the use of active liquid substances to remove pollution residues by dissolving, neutralizing, destroying microorganisms with their subsequent removal is the key to cleanliness and proper sanitary condition of the toilet. Components of liquid substances can prevent limescale deposits from used water on the surfaces of the toilet parts in contact with it.

Various methods are known in the art for arranging metering devices in a toilet. One way is the location of the metering device or some part of it in the cavity of the toilet. Significant disadvantages of these devices are: a) only part of the surface of the toilet bowl located under the device, located in the zone of interaction of the cleaning substance with water, is cleaned; b) the device or its individual parts are in the zone of contact with metabolic products, other washed away liquid or solid waste of human life and are subject to contamination by them, and regular cleaning of the external surfaces of the parts of reusable devices is necessary.

Placing the metering devices inside the toilet bowl eliminates the above disadvantages and contributes to the appearance of an additional positive effect in the form of the possibility of cleaning the inner surface of the tank for water.

An analogue of the invention is French patent FR 2808897.

The patent proposes a device containing a container for storing a liquid substance, having in its lower part a mouth for discharging a liquid substance extending into a cavity, inside which a movable spherical blocking element is mounted, attached to a float mounted in such a way that it floats on the surface of the water in flushing device. When the tank is filled with water, the float through the spherical blocking element closes the opening of the neck, thereby blocking the outlet of the cleaning substance. Conversely, when the flushing device is activated, the water level in the tank of the flushing device decreases, as a result of which the spherical blocking element allows the substance to flow out into the cavity and, at a water level insufficient for hydraulic communication with the float, overlaps the base of the cavity. Liquid substance enters the cavity and fills it. When the tank of the flushing device is filled, the float raises the spherical blocking element, thereby allowing the substance contained in the cavity inside the tank to flow out, and after a certain time, when the water level in the latter becomes sufficient, the spherical blocking element blocks the flow of liquid substance. In the present invention, a method is used when the dosing of a liquid substance is carried out during the discharge of water from the reservoir during the movement of the spherical element attached to the float, from the beginning of the opening of the neck opening to the closure of the outlet of the cavity.

The disadvantage of this method and a device based on it is that in the intermediate position of the spherical overlapping element, the cleaning agent does not have any obstacles for flowing directly from the storage container to the tank of the washing device both at the phases of the water discharge and the collection of water into the tank reservoir. At the same time, the amount of cleaning agent supplied in this way depends not only on the volume of the dosing cavity, but also on the time the spherical overlapping element is in the intermediate position. Factors such as the pressure of the water in the system, the characteristics of flushing devices installed by the manufacturers of toilets, influence the time of emptying and filling the tank reservoir. The rate of outflow of a liquid substance is affected by the level (column pressure) of the substance in the container, as well as the viscosity of the substance itself.

Thus, this invention does not ensure the accuracy of the supply of a liquid substance with each actuation of the flushing device.

The closest analogue is the metering device according to the patent of the Russian Federation No. 2395648. This device for dispensing a predetermined amount of liquid cleaning agent into the tank of the toilet flushing device comprises a dispensing cavity in the lower part of the liquid cleaning agent container, the volume V of which is close to the volume (V + v) of the substance to be dispensed. In the waiting phase, the tank is filled with water, the outlet of the cavity is closed by a float valve. A liquid substance fills the metering cavity through a small hole. When the flushing device is activated, the water level in the tank reservoir decreases, as a result of which the float, lowering, opens the valve, allowing the substance contained in the cavity to flow into the reservoir. The total volume of the substance discharged into the water depends on the volume of the dosing cavity V and the relatively small volume v of the liquid flowing out of the container directly into the tank through a small hole d = 0.6 during the open state of the cavity outlet until it is closed when water is taken into the tank tank. This device contains the ability to change the volume V by adding additional volumes to the existing cavity for a liquid cleaning agent. The device used a method of dispensing a liquid substance during water intake into the tank reservoir after closing the outlet of the metering cavity. The change in the volume of the dosed liquid substance is carried out stepwise.

But even in this device, the shortcomings in ensuring the accuracy of the delivery of a given volume of liquid substance have not been completely eliminated. There is a small variable component of the total volume of the liquid substance released into the water, which will depend on the viscosity of the cleaning liquids used. Even with a small influence, in accordance with the applicant’s claims, the time of the open state of the cavity outlet on the volume v, for low-viscosity, non-concentrated liquids, the flow rate, respectively, and the volume v will be greater than for viscous, concentrated. Another disadvantage is that during emergency water outages after using the toilet, due to the lack of water in the tank, the float will lower with the valve, opening the outlet of the dosing cavity. As a result, uncontrolled complete outflow of liquid substance from the container will occur. Another disadvantage is that the release of liquid substance occurs during the flushing of water into the toilet. Therefore, the released substance does not have time to dissolve, mix with water. As a result, part of the surface of the toilet bowl is not treated with a substance, some undissolved volume of the substance merges into the toilet bowl without participating in the treatment of its surface. Changing the dosed volume V during operation of the device is performed in steps by connecting additional elements to the device. This is inconvenient and is associated with the need to dismantle the device from the water tank.

The aim of the present invention is to eliminate the above disadvantages of the prior art by proposing a new dispensing method and a dispensing device based on it.

A method for dispensing liquid substances is proposed when a container 1 for dosed liquid substance 12 is placed in the liquid tank 13. The required volume V is dosed as a result of the relative, vertical movement of the system of hydraulically interconnected floats 5, 6. The dosed volume V of liquid substance 12 is discharged by displacing from the cavity 8 of the float 6 while filling the tank 13 with liquid.

Implementation of the dispensing method is carried out in a device for dispensing a given amount of active liquid substances, containing shaped racks 9 of the container 1, orienting the vertical axis of the system of two floats 5, 6, with the possibility of reciprocating movement. Moreover, the float 5 is located in the cavity 8 of the float 6 and has a hydraulic connection with it, the element of which is the liquid substance 12. The lower position of the float 6 is fixed by the hooks 10 and the supporting surface of the latches 11. The float system is designed to form a dosed volume V of the liquid substance 12 in the descent phase water into the toilet, closing the channel 3 of the neck 2 with the valve 4 and discharging the dosed volume V of the liquid substance 12 into the water during the phase of the collection of water into the tank 13.

Also proposed is a device that differs from the above in that it comprises means 20 with a channel 3 with the possibility of vertical, adjustable reciprocating motion, fixed through a threaded connection with the outlet neck 2 for stepless regulation of the volume V of the dosed liquid substance 12.

The second device, which differs from the above in that the cover 14 of the tank 13 has an opening for securing the container 1, and the gasket 15 may have parallel planes or planes converging at a certain angle to orient the axis of the device normal to the surface of the water in the tank 13.

The third device, which differs from the above in that it comprises a traverse resting on the end surfaces of the opposite walls of the tank 13 with an opening for securing the container 1.

The description of the invention is facilitated by the attached drawings.

In FIG. 1-5 shows a device for dispensing liquid substances, including individual moments of interaction of its parts or elements.

A device for dispensing a predetermined amount of active liquid substances according to the invention of the invention comprises shaped racks 9 of the container 1, orienting the vertical axis of the system of two floats 5, 6, with the possibility of reciprocating movement. Moreover, the float 5 is located in the cavity 8 of the float 6 and has a hydraulic connection with it, the element of which is the liquid substance 12. The lower position of the float 6 is fixed by hooks 10 made on the outer surfaces of the struts 9 and the supporting surface of the latches 11, combined with the walls of the cavity. The float system is designed to form a metered volume V of the liquid substance 12 in the phase of flushing the toilet, closing the channel 3 of the neck 2 with a valve 4 and discharging the metered volume V of the liquid substance 12 into the water during the phase of the collection of water into the tank 13.

It is important that the lower position of the float 6, determined by the hook-to-latch connection, should ensure the termination of the outflow of liquid substance from the outlet channel 3 by the valve 4 of the float system after the necessary volume V of the dosed substance is discharged into the cavity 8 of the float 6.

The device provides the use of liquid substances of various concentrations from low viscosity to viscous. During long-term operation, drying of viscous substances on the surface of floats in air is possible. To prevent changes in the mass-weight, geometric characteristics of the floats 5, 6, part of the metering device, including the float system, in the standby mode of operation of the flushing device are in a flooded position. In this case, the weight of the lid of the tank of the water tank and the container with liquid substance is incomparably greater than the lifting force of the float system. This also ensures that the metering device fits into the limited air space between the water level and the tank lid.

The angles of inclination of the inner and outer surfaces of the lid 14 of the reservoir 13 of the tank to the surface of the water at the place of the mounting hole for mounting the container 1 of different manufacturers may be different. To orient the axis of the metering device normal to the surface of the water and depending on the angle of inclination of the surfaces of the lid, the gaskets 15 may have parallel planes or planes converging at a certain angle.

The operation of the metering device is explained in the following description.

In FIG. 1 shows a metering device in the standby phase until the next operation of the mechanism for discharging water into the toilet. In this state, the water in the reservoir 13 of the tank is at the upper level B. The buoyancy forces F ₁ and F _{2 of the} flooded floats 5.6 channel 3 is closed by the valve 4. In this case, the float 6 is in the upper position, coming into contact with the supporting heel 7 with the surface of the float 5. The liquid substance is displaced from the cavity 8 of the float 6 into the tank and dissolved in water.

When the water release mechanism is triggered, the water level in the tank starts to drop. The float 6 begins to emerge from the flooded state, and the point in time (Fig. 3) at a water level B ₁ , the float system 5, 6 is still in a static state, since the sum of the gravity forces F _{t1 of the} float 5, F _{t2 of the} float 6 with it in the cavity with a liquid substance is less than the sum of the buoyancy forces F ₁ and F _{2 of the} floats 5, 6. At this level G of the liquid substance, the float 5 is in a flooded state.

With a further decrease in water level (Fig. 4), the float 6, which is in hydraulic relationship with the water level, also continues to sink. At a point in time at a water level of B _{2, the} float 5, being in hydraulic communication with the float 6, where the communication element is a liquid substance, leaves the flooded state. The liquid substance in the cavity of the float 6 takes level W ₁ . The height of the liquid level from the lower surface of the cavity is H, and the distance between the lower surfaces of the float 5 and the cavity of the float 6 is equal to h ₂ . The buoyancy force of the float 5 provides a closed state of the channel 3 by the valve 4.

A further decrease in the water level (Fig. 5) leads to the fact that the float 6, lowering along with the water level, takes the lower position fixed by the contact of the hooks 10 of the racks 9 with the supporting surface of the latches 11. The float 5, which is in communication with the float 6, is lowered , opens the channel 3. A liquid substance begins to pour into the cavity of the float 6. The liquid substance, filling the cavity, takes level Ж ₂ , at which the float 5, which has risen along with the level of the liquid substance, closes channel 3 with valve 4. The height of the liquid level from the lower surface the cavity cavity is H ^I , and the distance between the lower surfaces of the float 5 and the cavity of the float 6 is equal to h ^I ₂ . The lifting force of the float 5 for one liquid is a constant value. Therefore, the values of h ₁ and h ^I ₁ , determined by the buoyancy of the float for the same liquid, are equal. Therefore, the dosed amount of liquid substance poured into the cavity is determined by the value (h ^I ₂ -h ^I ₁ ). In the cavity of the float is a dosed volume of liquid V = S × (h ^I ₂ -h ₂ );

where S is the cross-sectional area of the cavity 8 of the float 6.

After completion of the discharge of water into the toilet, the release mechanism closes the outlet of the tank and the water coming from the water supply system begins to fill the tank reservoir. As it fills, water at a certain level enters into hydraulic communication with the float. With a further increase in the water level in the tank and the corresponding raising of the float 6, the float 5 enters the cavity of the float 6 until it contacts the supporting heel 7. The liquid substance is displaced from the cavity into the tank of the water tank. After the water reaches level B, the water supply to the tank tank is stopped. The water release mechanism and metering device are ready for the next operation.

Currently, for most toilets, removing the lid of the tank of the water tank is associated with the dismantling of individual fastening elements or controlling the mechanism for releasing water from the tank. Therefore, the mounting of the metering device to the lid of the tank reservoir is preferable, since during operation the filling of the liquid substance into the container is extremely simple. But in this case, before the release of toilet bowl manufacturers by manufacturers of an additional hole for mounting the metering device, there is a need to make this hole at home.

When using the tanks of the water tank, in which the lid is easily removable, it is possible to fasten the metering device to the side walls of the tank using a traverse (Fig. 6). The traverse 19 is fixed by a fixed connection to the end surfaces of the side walls of the tank 13 of the tank and has a hole for fastening with the nut 16 of the filler neck 18, which is closed by the lid 17.

The proposed dosing device allows the regulation of the volume V of the dosed liquid substance 12 (Fig. 7). For this, the outlet neck 2 comprises a means, which is a screw 20 with a channel 3 for the outflow of a liquid substance. At the upper end of the screw, two perpendicular slots are made for vertical adjustment through the filler neck of the position of the outlet of the channel 3 relative to the float system 5, 6. An o-ring 21 is installed in the annular groove of the screw. In the manufacture of the screw 20 from materials with elastic properties that ensure the tightness of the threaded connection with neck, o-ring is not installed. When screwing or unscrewing the regulatory means, the distance h ₂ between the lower surfaces of the float 5 and the cavity of the float 6 decreases or increases, proportionally decreasing or increasing the volume of the dosed substance. Regulation provides the opportunity for economical use of concentrated liquid substances.
