[0037] The remaining structure is the same as that of Embodiment 1.

[0038] During the use process, the motor drives the ball screw to rotate forward or backward, driving the lead screw nut 203b, the moving cylinder 204a, the cross bracket 204c-1, the pressing plate 204c-2 and the straight rack 204d-1 to move synchronously. During the movement of the two pressing plates 204c-2, the side ventilation assembly 301 and the middle ventilation assembly 302 are respectively repeatedly compressed for ventilation. During the movement of the straight rack 204d-1, the gear 204d-2 is driven to rotate, so that the fan blade 204d-4 rotates, accelerating the air flow in the groove body 101.

[0040] Refer to Figures 1 - 5, which is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the side ventilation component 301 includes two side elastic air bags 301a arranged on the inner wall of the end of the groove body 101, a side air inlet pipe 301b and a side exhaust pipe 301c arranged on the outer wall of the side elastic air bag 301a, a side drying cylinder 301d arranged outside the groove body 101 and used to communicate with the side air inlet pipe 301b, and a side connecting pipe arranged on the side drying cylinder 301d. Among them, the side drying cylinder 301d is filled with drying filler. The side air inlet pipe 301b, the side exhaust pipe 301c, and the side connecting pipe are all one-way ventilation pipes. The side connecting pipe only allows external air to enter the side drying cylinder 301d. One end of the side air inlet pipe 301b is communicated with the inside of the side elastic air bag 301a, and the other end extends outside the groove body 101 and is communicated with the side drying cylinder 301d. The side air inlet pipe 301b only allows external dry air to enter the side elastic air bag 301a; one end of the side exhaust pipe 301c is communicated with the inside of the side elastic air bag 301a, and the other end extends into the groove body 101. The side exhaust pipe 301c only allows the air in the side elastic air bag 301a to be discharged into the groove body 101.

[0041] The middle ventilation component 302 includes four middle elastic air bags 302a arranged on the left and right sides of the limit block 203c, a middle air inlet pipe 302b and a middle exhaust pipe 302c arranged on the outer wall of the middle elastic air bag 302a, a middle drying cylinder 302d arranged outside the groove body 101 and used to communicate with the middle air inlet pipe 302b, and a middle connecting pipe arranged on the middle drying cylinder 302d. Among them, the middle drying cylinder 302d is also filled with drying filler. The middle air inlet pipe 302b, the middle exhaust pipe 302c, and the middle connecting pipe are all one-way ventilation pipes. The middle connecting pipe only allows external air to enter the middle drying cylinder 302d. One end of the middle air inlet pipe 302b is communicated with the inside of the middle elastic air bag 302a, and the other end extends outside the groove body 101 and is communicated with the middle drying cylinder 302d. The middle air inlet pipe 302b only allows external dry air to enter the middle elastic air bag 302a; one end of the middle exhaust pipe 302c is communicated with the inside of the middle elastic air bag 302a, and the other end extends into the groove body 101. The middle exhaust pipe 302c only allows the air in the middle elastic air bag 302a to be discharged into the groove body 101.

[0043] During use, when the abutting plate 204c-2 presses against the side elastic airbag 301a to compress the side elastic airbag 301a, at this time, the side exhaust pipe 301c discharges the air in the side elastic airbag 301a into the groove body 101. When the abutting plate 204c-2 leaves the side elastic airbag 301a to make the side elastic airbag 301a recover from the compressed state to the original state, at this time, the side intake pipe 301b sucks the outside dry air into the side elastic airbag 301a for the next discharge. Similarly, when the other abutting plate 204c-2 presses against the middle elastic airbag 302a to compress the middle elastic airbag 302a, at this time, the middle exhaust pipe 302c discharges the air in the middle elastic airbag 302a into the groove body 101. When the other abutting plate 204c-2 leaves the middle elastic airbag 302a to make the middle elastic airbag 302a recover from the contracted state to the original state, at this time, the middle intake pipe 302b sucks the outside dry air into the middle elastic airbag 302a for the next discharge. By repeatedly expanding and contracting the side elastic airbag 301a and the middle elastic airbag 302a, the outside dry air can be sucked and discharged into the groove body 101 for dehumidification.
