SPRINKLER HEAD Russian patent published in 2020 - IPC A62C37/14 A62C37/36 

FIELD: liquid atomisation or spraying devices.

SUBSTANCE: sprinkler head (1) for sprinkler installation with linear section (2) for sprinkler liquid, made of electrically conductive material by shutoff body (5) for tight closing of outlet opening (4) of linear section (2), rigidly and electrically conductively connected to linear section (2) through support element (6) by section (7) of counter support made of electroconductive material, located between counter-rest section (7) and shut-off body (5) by thermal trigger element (8), wherein starting means are provided for controlled active thermal actuation of thermal trigger element (8) by active heating of thermal trigger element (8), characterized in that starting facilities include electric printed-circuit board (10) with control unit (12) located on it, as well as power supply (11) and electric conductive path (9) along thermal trigger element (8), wherein the electric printed-circuit board (10) has an upper side and a lower side and on the first side the upper side or the lower side is in electrical contact with shut-off body (5), and on second side of sides of upper side or lower side is in electrical contact with support element (6), wherein counter-support section (7) and shut-off body (5) in each case are in electrical connection with electric conductive path (9), so that by means of control unit (12) on printed-circuit board (10) there can be generated current passing through power supply (11) through support element (6), counter-support section (7), electric current-conducting path (9) and shut-off body (5) causing active heating and thus actuation of thermal trigger element (8).

EFFECT: sprinkler head is provided.
