Definitions

• the present invention relates to a device for the environmentally friendly treatment of small amounts of water with activated carbon and possibly with strong permanent magnetic fields, in particular in the kitchen and in the household.
• the treatment of water with strong magnetic fields is also of interest, since the surface tension of the water is reduced and the treated water therefore behaves like soft water. It is therefore particularly suitable for the preparation of coffee or tea. It is also of interest, for example, to prevent or at least reduce the calcification of coffee machines and steam iron.
• the invention has for its object to provide such a device for the environmentally friendly treatment of small amounts of water with activated carbon and possibly with strong permanent magnetic fields, which is particularly suitable for kitchens and households and can be used easily, inexpensively and safely .
• a device consisting of a non-ferrous metal, plastic or hose material pipe through which water can flow and a strong permanent magnet surrounding this pipe or fastened in the pipe, this device being connected to a funnel .
• Pipe diameter or the outlet of the same are to be dimensioned so narrow that a maximum of 10 1 / min can flow through with a water column of 10 to 50 cm.
• the device according to the invention must therefore additionally fulfill the task that a sufficient amount of water is passed through a sufficient amount of activated carbon in a sufficiently short time. This is not possible without using external water pressure.
• the task in particular with regard to activated carbon, can be achieved by connecting a cartridge filled with granular activated carbon and through which water can flow, with a plastic conical nozzle which can be pressed by hand onto the outlet of a water tap. If necessary, the water can also be used before or after are passed through a tube made of non-ferrous metal, plastic or hose material with strong permanent magnets surrounding this tube or adjacent to this tube.
• the nozzle has one or more planar extensions on the outside, which make it easier to press the nozzle onto the outlet of the tap.
• this areal extension consists of a disc firmly connected to the nozzle or of two areal extensions which are offset by 180 ° and which can be pressed with only two fingers at the outlet of the tap.
• the inner wall of the socket can be provided with a sealing element.
• sealing elements for example, sealing rings come into consideration, which are arranged, for example, in the form of an O-ring, in particular in a horizontal position on the inner wall of the connecting piece.
• the sealing element, in particular the O-ring is advantageously fastened to the inner wall, so that the position of the O-ring is not changed by pressing the water tap.
• the fixation can take place, for example, by gluing.
• a further preferred embodiment consists of the “inserted”. to fasten a sealing ring lying on a projection with a snap ring.
• the material of the connecting piece can be a flexible, rubber-like material, at least in the part that receives the tap, which closes elastically around the tap and, because of its tension, enables a seal.
• the nozzle can also be provided with a protuberance running around the inner wall and enable the water tap to be sealed off from the nozzle. The spout made of flexible material is pushed over the tap and the protuberance running around seals the spout after passing through a vent, for example, the tap. Due to the elastic behavior, the protuberance running on the inner wall tries to return to the rest position and due to the pressure involved, the protuberance clings to the outer wall of the tap.
• a conical rubber-elastic insert which in turn has annular knobs or depressions, can also be used in the conical connecting piece, which in turn ensures a better seal.
• the preferably conical nozzle has an angle of inclination that is large enough to accommodate different sizes of taps, on the other hand, is not so flat that it is no longer possible to provide adequate sealing when pressed on.
• the angle of the cone is therefore preferably in the range between 30 and 85 ° and in the simplest case at approximately 75 °. Since in some countries there are also taps with a aerator, which in turn is conical, the nozzle can also be non-conical, i.e. the angle can then also be 90 °. Even for such a nozzle, however, it is advisable to attach a rubber-elastic sealing ring and to secure it against changes in position by gluing or grooving.
• this configuration is very inexpensive, it may also be sensible to also supply such a conical perla. If necessary, a fitting piece that can be screwed onto this can also be supplied in order to be able to use the conical aerator more universally, particularly when traveling.
• a conical rubber sleeve with a Shore hardness of 40 to 75 °, with single, inner ones, has proven particularly useful Sealing rings is provided, attached to a suitable bead on the connector and is firmly connected to the connector with a sheathing plastic ring by welding the plastic ring to the connector. This welding is preferably carried out using ultrasound.
• plastics that are perfect under food law and have a certain elasticity are suitable as plastic for the nozzle.
• the granular activated carbon preferably has a grain diameter between 0.1 and 1 mm. Grain diameters of 0.5 mm have proven particularly useful. The uniform bed and uniform cleaning properties are produced above all if activated carbon with a grain size that is as uniform as possible is used.
• the cartridge In order to achieve a sufficiently large cleaning capacity, it is advantageous to dimension the cartridge so that it has a larger circumference than the nozzle.
• the two openings, namely the inlet and the outlet of the cartridge, are preferably closed off by sieve plates. which prevent the activated carbon from escaping undesirably.
• the lid and bottom of the cartridge are then preferably designed as very flat funnels, the central bore corresponding approximately to the diameter of the conical nozzle.
• a preferred embodiment with strong permanent magnets also has a sealing element between the tube which can hold the permanent magnet and the cartridge which preferably contains unscrewable activated carbon.
• This sealing element can for example, an O-ring made of rubber or other elastic materials. It is also possible to produce the sealing element, for example the sealing ring, from the same material as the material to be used for sealing the connecting piece towards the tap.
• the O-ring lies, for example, firmly against the outer wall of the tube receiving the permanent magnet in the area of the screw-in end (for screwing in the activated carbon container).
• the sealing element can be fastened by gluing or by letting it into a groove which surrounds the tube in the circumferential direction.
• a protuberance running around the outer wall of the tube holding the permanent magnet for example in the form of a web, can also be arranged.
• the sealing element is then coated on the thread side (opposite the opening receiving the pipe of the permanent magnet receiving tube) so that when the tube is screwed into the cartridge containing activated carbon, the sealing element is squeezed between the opening of the activated carbon cartridge and the circumferential protuberance.
• the protuberance running around the outer wall of the tube must be arranged at such a distance from the end that can be screwed into the activated carbon cartridge that sealing by means of the sealing element is made possible.
• the device according to the invention only consist of the nozzle and the cartridge, these can be firmly connected to one another and possibly even be largely produced in one piece during production. Such a device then only has to be provided with the upper sieve bottom, filled with the granular activated carbon, covered with a second sieve bottom and connected to the lower funnel of the cartridge serving as an outlet.
• the device according to the invention additionally has a tube with surrounding or adjacent permanent magnets, it is advisable to design the cartridge as a whole to be exchangeable.
• the devices according to the invention thus make it possible to use the pressure of the water pipe to treat water quantities between 50 ml and 5 l in the shortest possible time in such a way that it meets all requirements.
• the exchangeable cartridges with activated charcoal can be cleaned from 100 to 500 liters of water, depending on their dimensions, so that they are used up after a few weeks or a few months and should then be replaced.
• the permanent magnets do not lose their function, so that they can be used for many years.
• the water treatment with the device according to the invention is very environmentally friendly since no chemicals are used. Used cartridges with activated carbon can be easily burned or put in the household waste, especially if the wall of the cartridge and the filter bases are made of polyethylene and / or polypropylene.
• the treatment with strong permanent magnets also dispenses with the use of chemicals and does not lead to any problems with disposal.
• FIG. 1 shows the simplest embodiment, consisting of a conical socket and a cartridge with a granular activated carbon firmly connected to it. This is preferably at least partially impregnated with silver ions, so that subsequent germination is prevented.
• FIG. 2 shows a device in which the treatment is combined with activated carbon and permanent magnets.
• FIG. 3 shows a device in which, in a particularly preferred embodiment, a sealing element in the form of an O-ring, preferably made of rubber, is arranged in the nozzle.
• a sealing element in the form of an O-ring, preferably made of rubber, is arranged in the nozzle.
• Other, tentatively elastic materials are also suitable as sealing materials, such as, for example, silicone plastics and other materials used in the sealing industry.
• FIG. 4 shows a device according to FIG. 3 with an additional sealing element in the region of the end of the tube receiving the permanent magnet that can be screwed into the activated carbon cartridge.
• a sealing ring for example an O-ring made of rubber or another elastic material, is arranged between a web running around the outer wall of the tube and the upper edge of the thread of the activated carbon cartridge. This ensures a reliable seal between the tube holding the permanent magnet and the cartridge containing activated carbon.
• FIGS. 5 and 5a show a device which is particularly small and handy and is therefore particularly suitable for being carried on trips in order to be able to use the device practically anywhere where drinking water from pressure lines is available. Since the quality of the water is very different and fluctuating worldwide, it is possible according to the invention to provide better drinking water practically everywhere for private consumption.
• the device according to FIG. 5 consists of a plastic nozzle which can be pressed by hand onto the outlet of a water tap and a cartridge which is filled with granular activated carbon and through which water can flow, at least the upper part of the filling consisting of carbon which additionally contains mineral additives such as Contains zeolites and the lower part of the filling consists of coal, which is also impregnated with silver ions.
• Figures 6 and 6a show a device which is suitable for normal household use and also contains the two different types of coal mentioned above, but in two separate containers. These can in turn preferably be screwed together so that they can also be exchanged and replaced individually.
• FIGS. 7 and 7a show an embodiment of the device which has proven very useful for being carried on trips according to FIGS. 5 and 5a. It consists of the manually pressable plastic nozzle, an exchangeable cartridge that is filled with two types of activated carbon, a screw-on drainage chamber, a conical rubber sleeve that is attached to a bead on the nozzle and welded to the nozzle with a plastic ring. In order to also be usable on smaller taps, a second, narrower rubber sleeve can also be supplied, which can be inserted into the first rubber sleeve.

• FIG. 9 shows an embodiment with a permanent magnet using the same screw-on cartridge as in FIG. 8.
• Coal filters are preferably also used in the case of coal which, through special absorptive mineral additives such as silica, alumina and natural or synthetic zeolites, is able to remove heavy metals such as lead from the water. This can be of particular importance in houses or communities in which there are still lead pipes or water pipes soldered with lead solder, which lead to an undesired lead contamination of the water.

• lead solder which lead to an undesired lead contamination of the water.
• Such a material is manufactured and sold, for example, by Engelhard under the names ATC TM and ATS TM. It is impregnated onto the surface of microporous activated carbon granules.
• the carbon filters are therefore preferably filled with two layers of different activated carbon.
• the lower layer then preferably consists of activated carbon, which is impregnated with silver ions, while the upper layer consists of activated carbon, which contains no silver ions and is instead mixed or impregnated with the mineral additives.
• These two layers are preferably separated from one another by a sieve plate or a filter fleece.
• the upper activated carbon can both absorb the cationic heavy metals such as lead dissolved in water and remove the undesired components such as flavors, smells, chlorine and organic contaminants such as pesticides and herbicides.
• the upper and lower layers can be chosen to be the same or of different strengths.
• the lower layer is preferably again impregnated with silver ions.
• the cartridge can also be filled with a mixture of the two types of activated carbon. This mixture is at least initially as effective as the two types in separate parts of the cartridge.
• the service life of such cartridges may be a little shorter because silver ions can inactivate the mineral additives prematurely.
