Abstract: An aeroponic system with uninterrupted operation and energy saving comprises a first nutrient solution storage tank, a second nutrient solution storage tank, a gas storage tank, an air compressor and a planting module; compresses air in the gas storage tank mainly through the air compressor, and transports a nutrient solution stored in the second nutrient solution storage tank to the planting module for watering by gas pressure, the excess nutrient solution dripped after watering is recycled to the first nutrient solution storage tank, and is finally transported back to the second nutrient solution storage tank to complete a circulating supply system. Since operation is carried out through a high-pressure gas stored in the gas storage tank, an object of uninterrupted operation and energy saving can be achieved.

Abstract: An air intake valve apparatus for pneumatic tool, configured in an intake port of a pneumatic tool for controlling air circulations, mainly comprises a valve base configured in the intake port of the pneumatic tool, a stem configured through the valve base inside capable of shifting to a air-blocking position and a air-exhausting corresponding to the valve base and a flexible component propped the stem for keeping the stem on the air-blocking position regularly, wherein the stem has a first portion, a second portion and a mid-reducing portion, the mid-reducing portion is coupled to the first portion and the second portion respectively with different transiting surfaces so as to maintain the force driving the stem in constant no matter the air pressure entering the valve base is lower or higher.
