Shower nozzle sprays, and can play a part of fire extinguishing.
Preferably, being provided with magnetic valve on the water inlet pipe, being provided with the sonde body can control magnetic valve to open
The 3rd controller closed.
By using above-mentioned technical proposal, sonde body is sensed when catching fire, and signal can be transferred to the 3rd controller,
Three controllers control magnetic valve is opened, and is carried out water spray effect, is reacted rapider.
Preferably, the shower nozzle has multiple along the circumferentially distributed of housing.
By using above-mentioned technical proposal, shower nozzle is multiple along being circumferentially provided with for housing, and multiple directions can be carried out simultaneously
Water spray, makes the effect of fire extinguishing more preferable.
Preferably, being provided with interlayer in the housing, the water inlet pipe is arranged in interlayer.
By using above-mentioned technical proposal, by the way that water inlet pipe is arranged in the interlayer of housing, the cloth of enclosure interior can be made
Office is more succinct, and anti-antipriming pipe influences the wind-force that getter device is produced by enclosure interior.
Preferably, being covered with guard outside the sonde body.
By using above-mentioned technical proposal, guard, which is located on sonde body, can prevent mosquito from entering in sonde body, Jin Erfang
Only sonde body is reported by mistake.
Preferably, the shape of the guard is hemispherical, the guard is threadedly coupled with housing.
By using above-mentioned technical proposal, guard is threadedly coupled with housing so that guard is detachable, is easy to staff to tear open
Wash guard or maintenance sonde body.
In summary, the utility model has the advantages that：Interior rise fight generation a large amount of smog when, pop one's head in body-sensing
Smog should be arrived, and transmits a signal to the first controller, now the first controller can control getter device to start, is inhaled to first
Stomata produces getter action, so by outside smog by the first suction hole from indoor sucking-off, reduce smog to human body
Injury, while reducing stop of the smog to people's sight, more facilitates indoor occupant to escape.
