Description:

Foaming head

The innovation relates to a foam generation head, in particular is suitable in connection with high-pressure washing systems.

In Figure 1, a known foam generation head is shown. In a cylindrical interior 10 there are between two metal disks 12a, 12b provided with holes a larger number of plastic balls 13, for example 250 to 400 pieces. The supplied via the connection 14, offset with detergent Liquid is supplied to the cylindrical space 10 under pressure and swirls up the balls 13, the liquid foaming will. The foam then exits through nozzle 15.

The known arrangement has several disadvantages. Once the plastic balls 13 use each other through their mutual Collide relatively quickly> are proportionate expensive and awkward to handle, since there is always a relatively large number of balls for a given one Degree of foaming must be used. To form the cylindrical Three metal parts are also required inside the interior, namely the two perforated plates 12a and 12b and the spacer ring 16.

The innovation has set itself the task of a foam generation head which uses no moving parts and is easy to assemble.

According to the innovation, this is achieved in that as a means for foam formation at least three perpendicular to the longitudinal axis of the Foam generation head in the interior of the same spaced apart, provided with opening discs are provided.

Further features and advantages of the innovation emerge from the subclaims and the following description based on the drawing. Show it

Figure 1 is a longitudinal section through a known Schaumerz eugung skop f

Figure 2 shows a longitudinal section of an embodiment of a foam generation head according to the innovation and

FIG. 3 shows a cross section along the line III-III in FIG.

As can be seen from FIG. 2, the new foam diffuser head has a foam diffusion head a base part 24 which is connected in any way, for example by a screw connection, to a detergent source, wherein an air supply device can also be interposed. The detergent is pressurized through the feed opening 25 fed to the interior 20 of the foam generation head.

The cylindrical interior is in the embodiment by the end face 29 of the base part 24 on the one hand and formed by a cup-shaped part 26 on the other hand, which on his The bottom is provided with the nozzle 25. The cup-shaped part 26 is preferably screwed onto the base part 24. The pot

The föntiige part has an annular stop 28 for disks -..- ben 23

The disks 23 are perpendicular to the longitudinal axis of the foam generation head arranged, namely at least three disks. The disks 23 have openings 23a, preferably Bores of the same diameter, the same number and / or the same arrangement, so that the production of these perforated disks 23 is uniform. At their circumference, the disks are provided on one or both sides with an edge 27 which is approximately perpendicular to the surface of the pane. 1 The edge serves to maintain the spacing between the panes 23. Alternatively, flat panes 23 could also be used and the Distance must be maintained by means of intermediate rings.

The discs are preferably made of plastic, preferably made of a hard rubber-like plastic, so that they are relatively dimensionally stable.

A different foaming can be achieved in a simple manner that more or fewer disks, if necessary be arranged with intermediate rings in the interior space 20.

Alternatively, it would be possible to arrange the discs with a certain amount of play.
