Description

Liquid monitoring indicator

The innovation relates to a liquid monitoring indicator for hydroponics, consisting of a housing in which, depending on the liquid level a floating body connected to a display rod is arranged to be axially displaceable relative to the housing, the display rod protrudes into a transparent, detachable housing head piece provided with markings.

Appropriate monitoring display devices are required to be able to check whether or not hydroplant needs to be supplied with new fluid. The Indication by the upper end of an indicator rod, its position relative to one on the transparent housing head piece attached mark shows whether there is still enough water.

In order for the hydro plants to flourish, it doesn't just take the required amount of water, but at regular intervals an additional nutrient must be added. to

(12 327)

For this purpose, tables are supplied with the purchase of hydro plants, from which you can see the time interval at which the nutrient must be added. If you misplace such tables or not write down the data in one Calendar, there is a risk that the necessary nutrients will not be supplied to the plant, so that they will die can.

The well-known liquid level indicators often guarantee a reliable fluid check is not possible if the float is defective. So can with blown Floats that are manufactured as a unit, defective productions occur that lead to leaks lead so that liquid penetrates. The upper end of the indicator bar therefore no longer shows the correct one Amount of liquid. There are also floating bodies that are open at the bottom, facing the liquid, i.e. one Make a bell. As long as there is enough air in the bell, the indicator stick indicates the correct one Liquid level marked. If, on the other hand, liquid enters, false indications occur.

The object of the present innovation is to provide a liquid monitoring display device of the type described above in such a way that, from a manufacturing point of view, a there is a simpler structure, with different materials being able to be used inexpensively. In addition, the Users are given the opportunity to determine when nutrients need to be added to the liquid.

The object is achieved according to the invention in that the housing consists of a passage opening which can be plugged together with a sleeve having bottom part and a detachably insertable between the sleeve and the housing head piece There is an intermediate piece, which at its upper area adjoining the housing head piece is a rotatable about the housing axis Has marking, wherein the floating body in the sleeve and in the lower portion of the intermediate piece is displaceable is arranged.

In contrast to the prior art, in which the surveillance display device consists of three parts (indicator rod with float, housing head piece, housing lower part), is proposed according to the innovation, the housing in addition to the housing head piece and the indicator rod with floating body assemble a base part, a sleeve that can be connected to this, and an intermediate piece. This has the advantage that the individual elements can be relatively simple injection molded parts for which the necessary mold costs are low. In addition, the various elements can be made of different materials, which is particularly advantageous for the bottom part with the existing passage openings. Because it must be avoided that a plant ingrown takes place over the bottom part, otherwise it will be damaged when removing the device the plants would cause and, moreover, it would no longer be guaranteed that the float exclusively carried by the liquid. As a result

In order to ensure that the float with indicator rod always shows the correct liquid level, it is proposed in an embodiment of the innovation that the float consists of two composite sub-bodies produced by injection molding. Accordingly, the floating body is also be constructed from simple elements, which is ensured that liquid is not switched ζ - can penetrate, which is not always the case, for example, in the produced by blow molding bodies.

In the case of particularly calcareous water, the disadvantage is often found that the floating body is no longer free in the lower housing body is movable in the longitudinal direction. Rather, it partially adheres to deposited lime, the one Causes roughening of the inner surface, so that a correct display is not made. To avoid this, a Particularly noteworthy embodiment of the innovation proposed that the inner wall of the sleeve for spacing of the float from that in the housing in the longitudinal direction web. As a result, the swimming ( 'body only in contact with the end faces of the webs and is guided along them, so that even when deposited of lime there is no danger that the float will stick during the downward movement, so that a wrong to high fluid level is displayed.

Preferably is the marking on a web 28 running in the longitudinal direction on the housing head piece 18 for better clarity appropriate. The housing head piece 28 is understandably also transparent. The web 28 can then have three markings that correspond to a minimum and maximum fluid level and a middle one. The floating body 12 can, like FIG. 2

can be made available as inexpensive injection molded parts, the advantage being that the individual elements can consist of different materials, so in particular for the bottom part 12, in the openings 34 are provided for the passage of the liquid. By the marking element 32 is also has the advantage that no calendar notes or spreadsheets are required to determine when to add nutrient to the liquid. The adjustment of the marking element 12 in relation A marking 30 always gives the owner of a hydroplant the required information when the fertilizer is applied must be attached. Since the liquid has to be refilled more often than the fertilizer, it is always guaranteed that the deadline will not be missed significantly.
