In general, when the humidity inside the box 1 is normal, the driving wheel 10 does not work and remains still, the piston cylinder 8 is aligned with the discharge port 6, due to the influence of the day and night temperature difference, the temperature variable sheet 26 deforms and drives the ratchet wheel 27 and the cam 19 to rotate through the pawl plate 28, and then the cam 19 drives the driving plate 18 to move, the driving plate 18 reciprocates under the action of the cam 19 and the pressure spring, the driving plate 18 drives the piston rod 9 to move through the driven plate 17, so that the piston rod 9 performs piston movement to exchange air, air in the box body 1 and external fluid are realized, the condition that the single elements such as a magnet and the like are easily corroded and damaged when the air circulation in the box body 1 is poor is improved, the device uses the deformation of temperature change piece 26 under the difference in temperature round the clock as the power supply, has realized the automatic function that improves the mobility of air, need not to set up electric drive mechanism, practices thrift the cost, and is energy-concerving and environment-protective.

The left end of the rotating plate 29 is fixed by the pressure lever 30, and when the active plate 18 moves leftwards, the pressure plate 24 is clamped by the rotating plate 29, so that the pressure plate 24 cannot rotate, and the lifting plate 22 and the pushing baffle plate 23 can be smoothly pulled; when the driving wheel 10 rotates and drives the piston cylinder 8 to swing, the pressing rod 30 is staggered with the rotating plate 29, the piston cylinder 8 drives the baffle plate 23 and the lifting plate 22 to swing together, and the rotating plate 29 is not propped against the pressing rod 30 any more, so that the rotating plate 29 can rotate and is not bound to the pressing plate 24 any more, the pressing plate 24 can also rotate, the influence on the swing of the baffle plate 23 and other structures is avoided, the piston cylinder 8 can smoothly complete the swing action, and the water pumping and draining operation can be smoothly carried out.

When the driving plate 18 is extruded and moved by the cam 19, the lifting plate 22 is pulled open by the pressing plate 24, the clamping block 21 is further pulled open from the sealing plate 20, then the pressing plate 24 is in contact with the baffle plate 23 to drive the baffle plate 23 and the sealing plate 20 to move left, so that the vent hole 25 is opened, and the ventilation hole 25 and the exhaust port 6 are communicated with the outside to ensure that air on the inner side and the outer side of the box body 1 can smoothly circulate.

Driven plate 17 keeps fixed under supporting spring's the top pushes away and the effect of blockking of stopper, in fig. 6, when drive plate 18 moves left, drive driven plate 17 and piston rod 9 move left, when piston rod 9 moves left the top and is blocked by spacing boss, the drive plate 18 that continues the left side to move can make the fly leaf take place to deflect, then drive plate 18 moves to the left side of driven plate 17, drive plate 18 moves right afterwards, because the right side of fly leaf is blocked by the stopper, therefore, drive plate 18 can drive driven plate 17 and piston rod 9 and move right, so, drive plate 18 can drive piston rod 9 and be the piston motion, carry out the circulation of air through discharge port 6 with the external world, the air mobility inside box 1 has been improved.

Under the condition that the air humidity inside the box body 1 is normal, water liquid at the bottom of the detection tube 4 cannot be excessively gathered, when the air humidity inside the box body 1 is excessively high, the water liquid gathered at the bottom of the detection tube 4 is excessively high, the water level line moves upwards, the floating pad 13 drives the conducting strip 12 to move upwards, the conducting strip 12 moves upwards and then contacts with the on-off key 14, the driving wheel 10 starts to work and rotate, as the piston cylinder 8 is rotatably installed in the box body 1, the joint of the piston rod 9 and the convex plate is located at the eccentric position of the driving wheel 10, therefore, in the rotating process of the driving wheel 10, the piston rod 9 is driven by the convex plate to do piston motion inside the piston cylinder 8, the piston cylinder 8 can also swing back and forth, the piston cylinder 8 respectively aligns with the discharge port 6 and the water pumping port 7 when the piston cylinder 8 aligns with one port, the wing plate 11 can seal the other port, and prevent water liquid and water vapor from being re-dispersed back to the inside the box body 1 through the other port, through the time to the piston motion design for when the piston cylinder 8 aligns with the mouth 7 that draws water, carry out the suction action, with in the water liquid suction piston cylinder 8 in the detection tube 4, then piston cylinder 8 swings to and aligns with discharge port 6, discharge water liquid to the box 1 outside, when having realized at the inside humidity of box 1 high, the function of automatic dehumidification, the device is earlier with the moisture in the air collected, then the rethread dehumidification subassembly discharges and gets rid of, it is more pertinent to dehumidify, the traditional approach has been improved, heat the dehumidification by a large scale, lead to the condition of unit spare overheated and energy waste easily, dehumidification effect is better.

The air humidity in the box body 1 is detected by arranging the detection pipe 4, an electronic detection device does not need to be additionally installed, the use cost is reduced, and the consumption of electric energy is saved.
