Definitions
- Cartridge and mixing device for a hand-operated device for spraying mixed with an additive water
- the invention relates to a cartridge for a Zumischvorraum a hand-operated device for spraying water, in which an additive in the form of a liquid concentrate, such as a pesticide, is mixed.
- a liquid concentrate such as a pesticide
- the invention is not limited to the admixture of pesticides, but the application of other available in concentrate form chemical substances such as cleaning agents with the cartridge is possible.
- Additives in the form of a liquid concentrate, such as a pesticide is mixed are commonly used in crop sprays and are here connected via their water connection, which is preferably a pressurized water connection, by means of a pressure hose with a portable pressure vessel.
- This pressure vessel absorbs the already mixed with the respective additive water and can be pressurized by means of a manually operable or motor-driven air pump be, which forms an air cushion above the liquid level in the pressure vessel.
- the disadvantage of such an arrangement is that the pressure vessel, the supply hose to the spray device, the manual valve and the spray pipe can be contaminated with the admixed in the water additives, which can be toxic, but at least not environmentally friendly.
- Another disadvantage of these devices is that always a large amount of mixture must be applied, which is often not completely spent and then disposed of.
- WO 02 / 0515555A1 has disclosed a manually operable device for spraying water with an admixing device which comprises a mixing head to which a cartridge accommodating the concentrate can be releasably attached.
- the disadvantage of the device known from WO 02/051555 A1 is that the cartridge has a filling space in the manner of a cylinder, in which the concentrated additive is brought out of the cartridge into the mixing head by moving a displaceable piston.
- this is a very complicated device, on the other hand there is the problem that with the mixing chamber permanently installed in the admixing device, the admixing concentration can not be readily changed.
- No. 2,584,104 shows a tank into which the solvents, for example water, are introduced into a line. From the tank, a chemical is supplied to the flowing solvent or water and mixed into the water.
- the solvents for example water
- US Pat. No. 4,971,248 has disclosed a device for irrigating, for example, grass areas, in which a container, for example a chemical, is introduced into a conduit. The chemical is added via an outlet in a solvent, for example in a water stream.
- US Pat. No. 2,857,202 shows a device in which, in turn, from a container receiving chemicals, this container is introduced into a water supply line or solvent line, so that water from the container can be metered into the solvent when the line flows through it.
- the object of the invention is to overcome the disadvantages of the prior art, in particular to provide a cartridge that allows the use of different concentrates compared to the previously known cartridges when introduced into the admixing device, which are always optimally metered into the water depending, for example, the plant active ingredient or concentrate.
- the mixing chamber is not part of the mixing head of the admixing device, but part of the cartridge inserted into the admixing device.
- the cartridge itself comprises a mixing chamber with a first outlet opening or a nozzle device with nozzle opening for dispensing the spray, an inlet opening for water, which can be configured as a throttle with a throttle diameter, and a second outlet opening for the mixture generated in the mixing chamber of the cartridge ,
- the first outlet opening or nozzle opening has a diameter of 0.1 to 3 mm, in particular 0.1 to 1 mm, particularly preferably 0.1 to 0.5 mm, very particularly preferably 0.15 to 0, 3 mm and the inlet opening or throttle opening has a diameter of 1, 2 to 3 mm, preferably 1, 2 to 2.5 mm, in particular 1, 4 to 1, 9 mm.
- the diameter of the nozzle opening and / or the throttle opening is selected for the respective spray agent or concentrate which is introduced into the cartridge, so that the spray agent or concentrate can be applied optimally.
- the diameters of both the nozzle opening and / or the throttle opening determine the mixing ratio of the concentrate with the solvent, ie in the present case with water. This is due to the fact that different concentrates have different viscosities at the same temperature. The However, viscosities influence, inter alia, the mixing ratio. If the temperature rises, a higher mixing ratio is generally achieved with the same concentrate.
- the cartridge is detachably connected to the mixing head of the admixing device, for example via a detachable screw connection or a clip connection.
- the inner container, in which the spray is spent comprises a compressible material.
- Preferred materials are plastics or rubber-elastic materials.
- a preferred plastic is polyethylene (PE).
- the cartridge comprises an activator.
- the activator comprises an axially movable component, which can preferably be brought into different positions.
- the advantage of an activator which is designed as a separate component is that the activator, which is designed, for example, as an axial component, can be exchanged very easily.
- different mixing ratios must be set. This is done, for example, by using different activators for different concentrates, wherein the activators have different nozzle openings and / or throttle openings for different concentrates. By simply exchanging the activator it is then possible to use one and the same cartridge mold for different concentrates.
- the invention also provides a mixing device for a manually operated device for spraying water, in which an additive is introduced, wherein the admixing device is characterized in that the water supply line comprises a check valve.
- This check valve may be formed as a safety valve.
- a so-called backflow preventer is advantageously provided, which serves to prevent contaminated water from entering the water supply line with the admixture.
- the admixing device is equipped with a pressure regulator or pressure limiter in a first embodiment.
- the pressure regulator or pressure limiter is designed so that at the water supply side, an operating pressure in the range of 1 bar to 3 bar, preferably 1, 2 bar to 2.2 bar is present, regardless of which pressure prevails, for example, in the pressure vessel to the Pressure water supply line is connected.
- the invention also provides a manually operated device for spraying water into which an admixture is mixed.
- This device is characterized in that an admixing device according to the invention is introduced with a cartridge according to the invention between a spray pipe and a water supply line, preferably a pressurized water supply line.
- the water connection may preferably be connected either to the water network or to a portable pressure vessel. If a connection to the water network is provided, then the water mixing device can with the
- Cartridge for example, be part of a conventional garden hose system, such as is used for irrigating the garden.
- a conventional garden hose system such as is used for irrigating the garden.
- the Wasserzumischvorraum between the garden hose and a blasting unit with the water is discharged, be introduced.

- the cartridge has a first inlet 130 which when connecting the cartridge with the admixing device with a
- Water outlet 7 of the admixing device is connected. If water flows in, for example, the pressurized water supply line of the admixing device, not shown, water is introduced into the intermediate space 142 between the inner wall of the outer container 110 and the pressure-sensitive inner container 120 via the connection of the water line 7 and the water inlet opening 30. When water penetrates into the intermediate space 142 between the outer housing 110 and inner container 120, the material of the inner container 120 is compressed until the same pressure prevails in the interior of the inner container and in the intermediate space 140 between inner container and outer container. This serves to dispense concentrate or spraying agent from the inner container via a nozzle with a nozzle opening 140 into the mixing chamber 150. The nozzle opening 140 is also referred to as a concentrate outlet port.
- the mixing chamber 150 is part of the cartridge 100 itself in contrast to the known from the prior art embodiments in which the mixing chamber is part of the mixing device or the mixing head. In the
- Mixing chamber 150 which has an inlet opening designed as a throttle, water from the water line 9 of the admixing device is guided into the mixing chamber 150. Due to the design as a throttle with a throttle opening 160 is achieved that due to the pressure difference of the throttle there is a certain pressure gradient; There is thus a high pressure at the inlet side of the throttle and thus in the pressure vessel and a lower pressure at the outlet side of the throttle and thus in the region of the outlet opening or Nozzle opening 140. Due to this pressure difference between the pressure at the nozzle opening 140 and at the inner container 120 of the cartridge, a certain concentration of spray agent or concentrate is then discharged from the inner container 120. Depending on the concentrate, the throttle opening can be adjusted, in particular so chosen, so that an optimum concentration of spray agent or concentrate is discharged via the outlet opening or nozzle opening 140.
- the mixing of the spray is carried out as described in the mixing chamber via the outlet opening 140th

- the upper end part 2000 of the cartridge component is connected to a so-called activator 3000.
- the activator 3000 receives a needle 3010 having an exit opening 1140. From the exit port 1140, spray medium enters the mixing chamber 1150 from the pressurized spray container in the cartridge component 1000, as indicated by the arrow 3012.
- the mixing chamber is formed in the present case in the activator, which is associated with the cartridge and not the admixing or the mixing head.
- cartridge and activator could also be integrally formed.
- pure solvent here in particular water
- the mixing chamber On the part of the throttle 3160, pure solvent, here in particular water, is fed to the mixing chamber along the arrows 3016, which mixes with the spray agent added in the mixing chamber 1150 along the part 3012.
- the mixture of water or solvent and spray or the chemical substances contained in the cartridge occurs along the arrow 3018 at an outlet opening 1170 in the line 1011 a.
- the supply of water takes place via the water inlet opening 1030 along the arrow 3020.
- the pressure regulating device which reduces the pressure prevailing in the admixing device or the mixing head to an operating pressure in the region of the throttle on the input side, is marked 1032.

- the piston 3700 acts on the outside of the component 3500
- Plunger 3600 is preferably made of a rubber-elastic material and thus fulfills a sealing function.
- a channel 3620 is provided to the needle 3010. In the channel 3620 enters from the spray container in the cartridge via milled 3622 along the arrow 3624 spray or concentrate.
- this conductive connection between the nozzle opening 1140 and the spray container in the cartridge 1000 is only released when the plunger 3600, as shown in Figure 1b, is held down. If the plunger 3600 is in the upper position, as shown in FIG. 1c, the plunger seals the inlet via the cutouts 3622. When the cartridge component 1000 is withdrawn, spraying agent can not then reach the area of the exit opening 1140. In this way it is prevented that during storage, the outlet opening of the activator or the mixing chamber is glued or gummy by spray residue or concentrate residues.
- Outlet 1140 of the mixing chamber 1150 and the interior of the spray container consists. It is then also possible to provide different activators with different outlet openings 1140 for different concentrates.

- the housing acts as a spring and a force F occurs, whereby the projection 5010 of the mixing head housing moves in the direction of the arrow P and thus release the cartridge.
- the mixing head housing optionally includes a rotary knob 6000 which converts a rotary motion into an axial movement for moving the piston 3700.
- the piston 3700 is moved by the axial movement of the knob 6000 in a position in which the activator is spent as shown and in Figure 1b also described in the operating position, d. H. the plunger 3600 is moved to the position shown in FIG. 1b.
- the piston is raised and the ram is brought into the position shown in FIG. 1c. Due to the fact that the plunger 3600 is in the raised position, there is no longer any conductive connection between the nozzle opening 1140 and the spray container. As before, however, with the cartridge inserted, as shown in FIG. 1 b, water can flow into the mixing chamber 1150 via the throttle opening 1160. This makes you for a flushing of the mixing head to use. By flushing all contaminants can be discharged from the mixing head. The plunger is raised due to the existing operating pressure in the spray container, if no counterforce can be applied to hold down by the piston. After release of the cartridge component by pressure loading of the mixing housing in the area of the pressure points 5020, the cartridge component can be pulled down.
- FIGS. 1b to 1d of a mixing head and a cartridge consisting of cartridge component and activator which has been improved compared to embodiment 1a with numerous additional features, a bearing is possible with respect to the embodiment in FIG can not occur because there is no conductive connection between the nozzle opening and the spray container in the storage condition.

- the outer container of the cartridge component coincides with the outer housing 11100.
- an inner container 11002 made of an elastic material, which receives a certain concentration of the concentrate, for example, the rinsing agent, introduced. By compressing the elastic material, the concentrate received in the inner container 1002 is discharged via the needle 13010.
- the inlet 11162 of water into the activator component in the present case is formed from milling cuts 12002 in the axial direction into an upper end part 12000 of the cartridge component 11000.
- the upper end part 12000 of the cartridge component rests against the so-called activator 13000.
- the activator 13000 receives a needle 13010 having an exit port 13140. From the exit port 13140, the pressurized inner container 11002 in the cartridge member 11000 exits
- Concentrate or spray into the mixing chamber 11150 if there is a conductive connection between the inner container 11002 and the needle 13010.
- the concentrate or spraying agent entering through the inner container opening 20000 from the inner container 11002 into the outer space 20002 can not flow to the concentrate inlet opening 20004 of the activator 13000, since the outer space 20002 passes through a first seal 20006 serving as an O-ring may be formed, is sealed.
- the first seal 20006 bears against a stop 20008. Since the second seal 20010 is applied to the activator 13000 at the center of a water inlet port 20012, the water flow supplied through the water inlet port 20012 becomes one
- the embodiment according to FIG. 1e has the advantage that both the mixing chamber 11150 and the needle 13010 can be rinsed after the system has been put out of action, ie. H. no spray or concentrate in the
- the mixing chamber 11150 is formed in the present case in the activator 13000, but which is associated with the cartridge and not the admixing device or the mixing head 11001. Alternatively cartridge and activator could also be integrally formed.
- pure solvent here in particular water
- the mixing chamber 11150 Via the throttle opening 11160, pure solvent, here in particular water, is fed to the mixing chamber along the arrows 13016, which mixes with the concentrate or spray agent added via the needle 13140 in the operating state as shown in FIGS. 1g1 and 1g2 in the mixing chamber 11150.
- the mixture of water or solvent and concentrate or the chemical substances contained in the cartridge enters the outlet line 11011 along an arrow 13018 at an outlet opening 11170.
- the supply of water is via the water inlet opening 11030 along the arrow 13020.
- the pressure control device which reduces the pressure prevailing in the mixing device or the mixing head to an operating pressure in the region of the throttle opening 11116 is marked 11032.
- the pressure control device By being able to select the size of the throttle opening 11160 and the size of the diameter of the nozzle opening 13140 of the needle 13010, it is possible, as described above, to adjust the concentration at which the spray or concentrate is supplied to the water or solvent via line 11030 , is mixed. Since the throttle opening 11160 is formed here as a bore, the hole can be made very easily for different concentrates or spraying, in particular in the required accuracy with low production costs. This is an advantage over the embodiment as shown in Figures 1b-1d where the size of the solvent inlet port is determined by the size of the mill slot 2002.
- an axially movable component for example a pusher 13600, on which the needle 13010 is attached, is used.
- an outer surface 13500 At the upper end of the axially movable member or plunger 13600 is an outer surface 13500.
- the illustrated non-operating state according to Figure 1e acts on the outer surface 13500 no force, so that due to a hydrodynamic restoring force or the restoring force of Spring 21000 of the plunger 13600 is in the illustrated non-operating state, which allows purging of both the mixing chamber and the needle.
- the piston 13700 By one of the admixing unit associated rotary head 16000, which converts a rotary movement into an axial movement for moving the piston 13700, the piston 13700 is either moved to a position in which the activator as shown in Figure 1e, is not in the operating state or on the axially movable component 13600 of the activator acts and, as shown in FIGS. 1g1 to 1g2, spends the activator component into the operating state.
- FIGS. 1f1 the cartridge component 11000 with associated terminating component and the activator 13000 arranged in the terminating component are shown for the system shown in FIG. 1e.
- Fig. 1f1 shows this overall system, wherein the activator is found in the spray position of Fig. 1e.
- the mixing chamber 11150 in the activator component 13000 is assigned and not to the mixing head not shown in FIG. 1f1.
- Fig. 1f1 shows the overall system, wherein the cartridge component 11000 has an outer wall 11003 or an outer housing and an inner container 11002 made of an elastic material.
- the interior 11005 of the inner container receives the concentrate or the spray.
- a conductive connection between the inner space 11005 of the inner container in which the concentrate is stored and the activator 13000 forms the inner container opening 20000.
- the activator component in the non-operating state as shown in Fig. 1e, 1f1 is shown in detail in Fig. 1f2.
- the same components as in Figs. 1e to 1f1 bear the same reference numerals.
- a first seal 20006 of the plunger 13600 is sealed, with which the outer space 20002 of the activator is above the opening 20000 with the interior of the cartridge component and thus in a conductive connection with the concentrate.
- the second seal 20010 with which the entry of the water supplied via the water inlet opening 20012 to the activator can be controlled. If the component is in the position shown in FIG. 1f2, the second seal 20010 is located approximately in the middle of the water inlet opening 20012. In this way, the water flowing in the direction of the arrow 13020 is split into two streams, namely a mixing chamber flushing stream 20014 and a needle flushing stream 20016.
- the mixing chamber purge stream 20014 flows through a throttle opening 11160 in the
- the third seal 20060 seals the space 20062, in which the water flows from the mixing chamber.
- the current 13020 used for purging in the non-operating state is thus divided into two substreams in comparison to all the preceding examples. This makes it possible in addition to the mixing chamber and the needle 13010 to rinse, so that collect after use no concentrate residues in the needle and These can enforce, so that when used again due to the closed needle, the entire system fails.
- FIGS. 1g1 to 1g2 the operating position of the third embodiment of the invention according to FIGS. 1e to 1g is shown. Will the illustrated in Fig. 1e
- FIG. 1g1 shows the entire cartridge with cartridge component 11000 and activator component 13000.
- the optimum concentration can be set for each individual spray.
- this is simply possible for the embodiment of the system illustrated in FIGS. 1e to 1g2, in that for different spraying agents or concentrates, the underside 20090 of the plunger 13600 is varied in diameter D.
- the diameter D of the plunger is always smaller than the diameter of the opening 20000.
- Fig. 1g2 again the same reference numerals are used for the same components as in Fig. 1e - 1g1.
- the axially movable component 13600 in the activator, the so-called ram, is brought into the operating position by pressing down on the surface 13500 in FIG. 1g2 with the aid of the piston (not shown).
- the underside 20090 of the plunger 13600 is thus moved into the region of the opening 20000 to the cartridge 11000, resulting in an effective opening 20092, which is defined by the diameter D of the plunger 13600 at the lower end.
- the first seal 20026 no longer abuts the stop 20008 of the activator 13000.
- the concentrate flowing into the space 20002 through the opening 20092 along the arrow 21002 can be seen along arrow 21002
- Fig. 1 h is a plan view of a knob 16000 is shown, with the rotary motion of the rotary knob 16000, the rotational movement is converted into an axial movement of the piston, not shown.
- the knob has a total of 3 positions, a first position 30000, in which the cartridge can be changed.
- a second position 30002 which indicates the operating state, the so-called mixing operation, in which the piston is brought downwards, as shown in FIG. 1g2, and thus Concentrate with solvent, especially water is mixed, and a third position 30004, the so-called.
- Spül ein which is shown in Fig. 1.c and 1f2, in the solvent, in particular water both by needle and mixing head (Fig. 1f2) or only is passed through the mixing head (Fig. 1c) and so both mixing chamber and needle of residues of the concentrate is flushed.
- FIG. 2 there is shown an admixing device constituting a hand-operated device for spraying water blended with an additive in the form of a liquid concentrate, such as a plant protection agent.
- the admixing device 1 is constructed as shown in FIG. 1 a and introduced between a spray tube 200 and a manual valve 220 with a pressurized water connection 224. Further illustrated is the disposable cartridge 100 of FIG. 1.
- the disposable cartridge 100 is shown in FIG. 1 a, inserted into an outer container 105 with the cartridge outer wall 110.
- the outer container may be formed as a screw-in vessel 105 comprising a thread 5. If the thread 5 is screwed into the thread 3 of the admixing device and previously the cartridge with the outer wall 110 inserted into the receiving device 105, the cartridge with mixing head 150 is introduced into the admixing device, that an outlet of admixed spray is prevented.
- Einschraubkartusche cartridges 1000 and 11000 can be used as in Fig. 1b - 1 h. Even with the cartridges is activated only by the rotation in the mixing position (mix mode) as shown in Figure 1h.
- the disposable cartridge may be designed differently for different substances, in particular comprise different mixing heads.
- the manual valve 220 comprises a handle 226 via which the manual valve 220 can be actuated.
- the manual valve 220 is a high-speed valve that opens fully when actuated via the hand lever 226 and immediately upon release of the hand lever 226 closes.
- the manual valve 220 may be connected via a pressure water connection 224 either directly to a pressurized water line or to a pressure vessel.
- FIG. 3 An embodiment of the invention with a pressure vessel is shown in FIG.
- the same components as in Figures 1a-h and 2 are assigned the same reference numerals.
- the pressure vessel 300 is shown.
- the pressure in the pressure vessel is indicated by means of a manometer 310.
- the pressure vessel further comprises a manually operated one
- Air pump 320 with which the pressure vessel 300 can be pressurized.
- the manual valve 220 and thus the admixing device 1 is connected to the pressure vessel 300 via a pressure hose 330, which in this case represents the pressurized water supply line.
- a pressure hose 330 which in this case represents the pressurized water supply line.
- a cartridge for an admixing device is specified for the first time, which is easy to replace and, in particular, always ensures optimum mixing of the spraying agent present in the cartridge into an admixing device.
