Atomizer nozzle

An atomizer nozzle for automatic dispensing of a liquid for fire-fighting systems, said atomizer nozzle comprising:

• a main body, comprising:
• an inlet, configured to be supplied with said liquid,
• an outlet, and
• a cavity, extending from said inlet to said outlet;
• a dispensing head, movable along said cavity, said dispensing head being configured to dispense said liquid beyond said outlet and, therefore, outside said atomizer nozzle;
• and
• a locking assembly, configured to lock said dispensing head in a locked position at a distance from said outlet;
• wherein said locking assembly comprises a thermosensitive element configured to break at a predetermined temperature, said locking assembly being further configured to automatically release said dispensing head from said locked position when said thermosensitive element reaches said predetermined temperature;
• wherein said dispensing head is further configured to:
• move along said cavity when released, thereby reducing said distance until said distance is eliminated, and
• dispense said liquid by protruding from said outlet;
• wherein said main body further comprises an upper half-body and a lower half-body, wherein said upper half-body comprises said inlet, wherein said lower half-body comprises said outlet, said locking assembly being accommodated in said lower half-body, and wherein said lower half-body is coupled to said upper half-body in a movable manner;
• and
• wherein said lower half-body is movable between a first opening position, in which said locking assembly locks said dispensing head in said locked position while said dispensing head obstructs said cavity, and a second operating position, in which said locking assembly locks said dispensing head in said locked position but said dispensing head puts said outlet in fluid connection with said inlet.
