It is limited by tube body 702, while making metal block 715 far from the first sheet metal 724, the second metal by insulating blanked clamper 714
Piece 725 when medical fluid is filled it up with, opens manual power switch 721, when the water in medicine-chest 2 gradually decreases, what piston rod 711 was subject to
Thrust is smaller, so that weight plates 710 generate pressure due to self weight and to piston rod 711, so that piston rod 711 is into tube body 702
Contracting, while driving metal block 715 to decline by insulating blanked clamper 714, until piston rod 711 limited by stop collar 705, medicine at this time
Medical fluid in case 2 is in low liquid level state, while metal block 715 is contacted with the first sheet metal 724, the fitting of the second sheet metal 725,
Alarm 720 by metal block 715 and the first sheet metal 724, the second sheet metal 725, the first wiring 722, the second wiring 727,
Manual power switch 721 and power supply are in closed state, therefore realize the purpose of low liquid level warning.
In conclusion the technological progress that the present invention obtains compared with the prior art is: have the function of low liquid level warning, it can
During application, when medical fluid is in low liquid level state, low liquid level warning is carried out, unmanned plane is maked a return voyage powder charge in time
Liquid avoids the time that unmanned plane during flying is round-trip in no medical fluid from occupying the time sprayed insecticide, and saves the time, helps to reduce
The time sprayed insecticide, to be conducive to improve spray pattern.
