Gradual change 17 slide downward of slot when, have the effect scrolled down through, 20 energy of protrusion that diameter is sequentially increased during rolling
It enough rotates rotor plate 19 more, extruding water outlet preferably is carried out to water-absorbing sponge 8, further improves the energy of fast squeezing
Power.
19 upper surface arc of the rotor plate setting, and its upper surface is fixed with multistage ladder 21；When rotor plate 19 is pushed away
It is dynamic and when squeezing water-absorbing sponge 8, the water energy of extrusion is enough to assemble at arc, when by the horizontal segment of multistage ladder 21, there is one
Parabolical motion profile has and goes out speed faster, can accelerate the impact force of water obliquely, makes water quickly through water suction sea
Silk floss 8 enters in water receiving case 12.
1 inner wall of shell right above the air inlet 11 is provided with rotating vane 22, and there is diversion trench on 22 surface of rotating vane
23；By the air of the air inlet 11 at 1 top of shell, rotating vane 22 can be pushed to rotate, rotation first by rotating vane 22
22 temperature of blade is lower, can condense out the moisture in air, and the rapid aggregation of the diversion trench 23 by its surface,
When rotating vane 22 rotates, the water of aggregation can be thrown away farther, closer to water receiving case 12, reduce water flow in top plate 6
On run duration.
When work, when gas is drawn into shell 1 from the external world, air inlet 11 is first passed around, then by first on top plate 6
Secondly open-work 9 and water-absorbing sponge 8 pass through the second open-work 10 of bottom plate 5, when by top plate 6,6 temperature of top plate is lower, can be right
Moisture in air has condensation effect, can be by the tide in air when then passing through water-absorbing sponge 8 by the air to dehumidify for the first time
Gas carries out second and dehumidifies, and finally reaches 5 bottom of bottom plate, light by the second open-work 10 of bottom plate 5 by the air to dehumidify twice
Source generator 2 issues light source and is received after the refraction of VOC and inductor 3 in air by photodetector 4, realizes to dehumidifying
The monitoring of VOC afterwards is conducive to the precision for improving monitoring, and final air is removed out of shell 1 by breather cheek valve 13, passes through
After the use of a period of time, by detection water-absorbing sponge 8 to the pressure of bottom plate 5, after reaching certain pressure, start electric pushrod
7, electric pushrod 7 squeezes top plate 6, and top plate 6 squeezes water-absorbing sponge 8, slides the water in water-absorbing sponge 8 along 5 upper surface of bottom plate
Into water receiving case 12, the water suction saturation of water-absorbing sponge 8 is prevented, and the water condensed at the top of top plate 6 can enter by interface channel
Into water receiving case 12.
