The working principle is as follows:

when the water absorption pad is used, when an object with moisture contacts with the water absorption pad, the water absorption layer 1 can absorb the moisture, and the moisture falls to the position above the bag body through the water inlet hole 11 under the action of gravity. Air exhaust device forms the negative pressure in the internal portion of bag, inhales moisture through crossing water hole 21 with the internal portion of bag, and moisture flows through crossing the water clearance, gets into interior suction pipe 31 to bag edge through suction hole 311, then reachs outer suction pipe 33 through the three-way pipe, behind the filter 43 of retrieving bottle 4, is retrieved bottle 4 and tentatively collects.
