Problems solved by technology

For this purpose, mechanical components such as valves, springs and / or seals are used in known sprinklers, which on the one hand increase the manufacturing costs and, on the other hand, also increase the risk of failure of the sprinkler
In addition, when the sprinkler is aged, the internal pressure in the flow passage of the sprinkler increases, causing water to possibly overflow from the air suction nozzle

Embodiment Construction

[0015] figure 1 A partial view of a sprinkler head 1 with a sprinkler housing 2 is shown in a sectional view. The basic structure of the sprinkler head 1 is described in column 2, line 61 to column 5, line 19 of DE 41 13 289 A1. The stated content of DE4113289A1 is incorporated in the present invention by reference.

[0016] The sprinkler head 1 has a jet shaper 15 with an insert body 16 , a housing bell 17 , a distributor 7 , a central body 18 and a jet discharge plate 19 . The insert body 16 is fixedly connected to the sprinkler housing 2 and basically serves the purpose of supplying the water flowing in through the opening 20 to the subsequent channel system of the sprinkler head 1 or of the jet shaper 15 . The housing bell 17 and the jet outlet plate 19 are connected to one another in a rotationally fixed manner, so that the user of the sprinkler head 1 (for example via the handle body 13 ) rotates the jet outlet plate 19 about the axis of rotation 14 and correspondingly...

Abstract

The invention relates to a sprinkler head (1) which is provided with a sprinkler casing (2) with at least one flow channel (3,8), wherein the at least one flow channel (3,8) is provided with a nozzle (4); when water flows in the flow channel (3,8)through the nozzle (4), low pressure can be generated, absorbing air into the at least one flow channel (3,8) through a channel (5), wherein at least one flow channel (3,8) can be closed so as to allow water to be discharged from the channel (5).

Description

technical field [0001] The invention relates to a sprinkler head, by means of which air can be mixed into the spray jet. Such sprinkler heads are used in particular in showers or bathtubs. Background technique [0002] Sprinkler heads are known from the prior art, by means of which different water spray jets can be generated. A sprinkler head is known, for example, from DE 41 13 289 A1, with which "strong jets", "weak jets" and "pulse jets" can be generated. In order to form a defined water jet, it may be desirable to mix air into the water jet. To generate the air-entrained water jet, air is introduced from the outside into the water-conducting part of the sprinkler device. For this purpose, known sprinkler devices use mechanical components, such as valves, springs and / or seals, which on the one hand increase the manufacturing costs and, on the other hand, increase the risk of failure of the sprinkler device. In addition, when the sprinkler is aged, the internal pressur...
