The invention is thus used wherever hygienic conditions must be taken into account, what is particularly the case in trees used for medical care or in hospitals. About that In addition, the device according to the invention is used wherever there is a gathering of people, such as in waiting halls, administration buildings, department stores or large sales areas.

In addition to these areas of application, the device according to the invention is also always used in cases where in maintain a regular and slow diffusion of active vapors of any effect in a given atmosphere should be. Thus, the device can also be used for atomization purposes in silos, greenhouses, storage rooms or the like for plant protection, fungus control, disinfection, Insect control etc. are used, ^ uch can use the device according to the invention in rooms of industrial yeast and poultry breeding, etc. for improvement of the air, namely where there is a constant fight against mass diseases caused by germs which can spread quickly and thus endanger the entire livestock and poultry population.

Devices are already known which focus on the atomization of active vapors in the air of certain rooms are and the known design a container or a bottle for pressurized with an inert gas Have active substances and are connected to an atomizer, which in turn is intermittent operated by a programming device such as a timer, which has the regular intermittent atomization cycle

triggers within the room.

However, these devices do not do their job properly and do not meet the requirements placed on them.

In these known devices, the active substance reservoir assigned to each device must be regularly renewed or replaced will. This renewal is more frequent, the higher the consumption and the more limited the capacity of the container is. Such containers or memories consist of a metal housing, the so-called standard bottle. The bottles currently available are of limited capacity. It is difficult doing them to develop further in this form and to enlarge the dimensions, otherwise due to the heavy weight If the bottle is filled with liquid but is oversized, it will be more difficult to change it same result.

Now the regulated operating sequence is an important condition for the effective atomization of the substances, so that the nature of the ambient air remains essentially constant. It is easy to see that too high a concentration of active substances in the air of the room endangers living beings, whereas one too low a concentration does not reach the effectiveness threshold of the substances. For this reason it is necessary and therein lies an indispensable condition for the effectiveness of this technique, a regular and precisely dosed one To ensure that the active vapors or mists are dispersed in the treated rooms. The previous Devices achieve this goal at the expense of the operator

709836/1003

sonals that the state of the mentioned containers or storage vessels with very great frequency and regularity has to monitor to ensure that the available quantity of the remaining substances for the Dusting is sufficient until the next inspection round. But this control is also special on your part disadvantageous conditions, because the operator has no other means to determine the filling level of a bottle than this from the device to remove and estimate from the weight whether the remaining ^ tightness is sufficient.

The device according to the invention is aimed at eliminating these disadvantages and over a longer period of time and, under very regular operating conditions, the scattering of active vapors or mists in a walled one To ensure space, whereby the maintenance staff is relieved of the burden by extremely frequent Inspection corridors to have to estimate the filling level of the storage container.

The invention accordingly relates to a device for regular scattering and intermittent atomization of active substances in the form of vapors or mists into the ambient air, these active vapors or mists in liquid form and under pressure are taken from a storage container with an atomizer in the manner of a Aerosol is connected, wherein the device has a control in the manner of a timer or clock, by a mist of active substances from the container is atomized at pre-set intervals. The device is characterized in that it has several separate reservoirs for the pressurized Has active substances and a transmission element,

709836/1003 _ ₅ _

on which the intermittent control (the timer) acts and the transmission element in sequence only the first container and after emptying the first a second container into operation, each Container is connected to means by which the storage container, which no longer contains any active substances, is out of order is set.

Other features and advantages of the invention will become apparent from the following description taken in conjunction represents with the drawings a special Auführungsbeispiel, however, on which the inventive idea not restricted. Show it:

Figure 1 is a schematic view of the various mechanical and electrical parts of the invention Contraption;

2a and 2b show a cross section of the device, from which in particular the pivoting movement of the container can be seen from its active (2a) into its passive position (2b), and

Figure 3 is an external view of the device.

In the embodiment shown here, the device according to the invention has a square housing on, which can be used in particular in the wall position. This case 1 has a front door 2, which can be pivoted to release the interior 3, into which the containers or bottles 4, 5 and 6 are known Design and large capacity.

- 6 709836/1003

The container content is 4 liters. After the Figures 2a and 2b it can be seen that each container is from an active position shown in Figure 2a can be tilted into a passive or inoperative position of FIG. 2b.

The full container (Figure 2a) rests in equilibrium on an obliquely cut plane and the rear bearing point 7 »which in turn is mounted on a flexible, calibrated spring leaf 8.

When the container is full (Fig. 2a), it can easily tilt the front section due to its weight compensate for the trimmed plane. The load-bearing surface of the container is calculated so that it is in Empty state or almost empty state shifts its focus in such a way that the container then moves forward tilts and thus assumes the passive position.

During this movement, the bearing point 7 is lifted upwards by the action of the spring, whereby the small switch 9 completes a signal circuit and energizes an indicator, for example in the form of a control lamp through the cover plates 10, 10 'or 10 "through the empty state of the respective container on the The front of the case.

The mode of operation of the device will now be explained in more detail with reference to FIG.

All containers 4, 5 and 6, here three (the number but can be significantly higher or limited to 2) are on a plate 11 on the same

709836/1003 " ⁷ "

Level, each container being connected to a bearing point 7 designed to be tilted.

Each container has a per se known upper spray nozzle 12, 13 and 14, which consists of an open cylindrical attachment with the outlet opening for the radial jet is formed. The containers are set up here in such a way that the nozzle emits a jet to the outside delivers, i.e. in the direction facing away from the device.

The device has a transmission element, which here consists of a rail 15 that is connected to the pushers 16, 17 and 18 of different and decreasing dimensions is provided.

According to the drawing, the pusher 16 is longer than its neighbor 17 »which in turn is longer than pusher 18.

In this situation, the lowering movement of the rail 15 first brings the trigger 16 into contact with the spray nozzle 12, whereby when the container 4 is put on, a jet of mist emits, as long as the rail in the lower or active position. However, the contact of the trigger 16 with the spray nozzle 12 prevents that pushes the rail further downwards and thus the pushers I7 and 18 do not contact the spray nozzles I3 and 14, respectively can, which is why only the container 4 is put into operation when the rail I5 is moved.

If the container 4 is exhausted, it is in the inoperative position brought as already described.

Now hits due to the vertical shift the rail 15 of the descending pusher 16 no longer on the spray nozzle 12 (which is caused by the tilted container no longer stands vertically) but hits the void.

In this Jachlage the trigger 17 with the spray nozzle 13 come into contact and thus after emptying from container 4 put the next container 5 into operation. As long as the container 5 is in the operating position vertically below the pusher 17 is, the rail 15 will always allow the pusher 17 to be placed on the spray nozzle 13, so that here, too, the rail is not lowered any further and thus the pusher 18 the spray nozzle 14 of container 6 can not achieve.

If the container 5 is exhausted, it in turn tilts into the passive spray nozzle 13 set out above, so that the subsequent movement of the rail 15 penetrate so far downwards can, until the trigger 18 in turn contacts the spray nozzle 14, whereby the container 6 in operation is taken.

The empty state of containers 4 and 5 and their inactivation are activated by the lighting of the indicator lights 10 'or 10 "are displayed.

This means that the person responsible for monitoring the entire system becomes the empty container is displayed so that it can replace the empty container with a full one.

Accordingly, the operator no longer has to be on site and place inspect the containers by lifting each one up and then putting it down again to determine the degree of filling, as this is now on the front displayed on the device.

In addition, on the one hand by the larger number of accommodated in a device and of Your used containers avoided that the latter have to be replaced too often, since it is now permanent Reserve can be kept in the device and a more flexible exchange is possible. So that can Personnel in widely spaced inspection corridors check the filling status of the device secure and make the necessary replacements without handling the large-volume containers and having to carry around things not to mention the security issues associated with the under Pressurized containers brings with it problems that relate to the insertion of the container.

The rail 15 is by suitable operating and Drive element shifted vertically, which be an electromagnet lc j mn. In the illustrated embodiment a motor 20 is used, which is connected to a transmission rod 21, which is on the terminating end the rail acts, which is advantageously pivotable at its other end 23.

The whole thing is controlled by a timer unit which consists of a gear motor $ 1 which drives the cam 32, which is a few degrees Has recess (which can be achieved, for example, by the addition of two cams that are jammed together lets, whereby the opening angle 33 and consequently the fogging period can be adjusted).

The cam is followed by a pinger 3 which controls contact 35.

If the finger reaches the recess or recess 33 ', the contact 35 remains closed during the dwell time of the finger YES in the recess 33, so that the motor 20 which drives the rail 15 carrying the handle is fed.

The auxiliary circuit 36, which runs via the opener 37, represents a safety device that serves to feed the motor 20 until the rail 15 in their superscript returns.

In the open position of the contact 35, the finger y \ - can be taken along by the cam, while the motor 20 has guided the rail 15 into the lower position. The unit is then locked and stopped in the lower position, which would mean an uninterrupted outflow of mist to be avoided. The circuit 36 represents an auxiliary circuit which feeds the motor 20 via the break contact 37 on which the lever 38 acts. When the rail 15 is in the low position, the lever 38 pushes the contactor of the miniature switch 37 back and lets it come into contact with the contact block 37 ', whereby the auxiliary circuit 36 is closed and the supply of the motor 20 is maintained for as long until the rail 15 returns to the upper position.

The opener 37 then opens the auxiliary circuit 36 again. In this position when the finger 3 ^ is still within of the opening angle 33 of the cam 32, the contact 35 remains closed and the motor 20 starts a new sequence. If, on the other hand, the finger 3 ^ · reaches the spaced position and the contact 35

opens, the motor 20 remains, which is neither from the main nor fed by the auxiliary circuit 36 is shut down and the fog scattering comes to a standstill until the following Cycle begins, i.e. until the next opening angle 33 passes the contact finger 3 ^.

The lever 40, which is brought into the locking position by the spring 41, forms safety locks. This lever lies perpendicularly under the rail 15 and therefore hinders any Downward movement of the rail for active fog spreading.

The electromagnet 42, which is fed in parallel from the supply circuit of the motor 20, acts on this lever 40 will. If the supply circuit is closed by the contact 35, the motor 20 and the electromagnet are accordingly 42 is fed and the mist is released, while at the same time the motor 20 actuates the rail 15. This facility ensures the safety of the unit, especially in the event of a power failure, e.g. in the course of of the atomization process could occur when the motor 20 is just pushing the rail 15 into the Has brought contact position with a container. If the motor comes to a standstill, it locks the pusher, and this would continue the aggravation process. However, since the electromagnet is no longer fed, it works no longer on the lever 40, whereupon the latter returns to the upper position under the action of the spring 41 and the rail 15 pushes upwards during its V-angled movement, so that it is under the action of the pusher Spray nozzle is released.

The device according to the invention thus works with absolute security and can be left to its own devices, with those stored in the containers Active substances at regular intervals (and according to the means of the profile and the speed of rotation of the cam 32 created program) are atomized. The device does not require any maintenance. It was also shown that the intended safety devices flawless work even under special events that can be traced back to a power failure or the like enable the entire system.

Accordingly, maintenance based only on replacing the container is required, as indicated by the control lights is facilitated, which instantly show whether and how quickly a replacement of the exhausted one is required Container is required or not.

This replacement is done by removing the empty The container is removed and the containers that are still operational are moved to the left. For example, if the containers 4 and 5 are empty, the container 6 is in the position brought from container 4 and two fresh containers become brought in the place of the containers 5 and 6. Through this in particular, it is avoided that the container 6 does not remain in the device for too long without until the storage or expiration date to be consumed. As a result, the container 6, which has not been used, arrives in the first user position and will then be replaced in the next substitution course.
