A first extension cavity 116 is formed between the bent portion of the third sidewall 113 and the second sidewall 112, and a second extension cavity 117 is formed between the bent portion of the fourth sidewall 114 and the second sidewall 112. The intake pipe 17 is connected to an outer end portion (end portion away from the inside of the base 11) of the first extension chamber 116, and the exhaust pipe 18 is connected to an outer end portion (end portion away from the inside of the base 11) of the second extension chamber 117.

The slider 12 is arranged in the base 11 with a smaller dimension between the third side wall 113 and the fourth side wall 114 than the base 11, thereby enabling the slider 12 to slide in the lateral direction, i.e. towards the third side wall 113 or the fourth side wall 114.

Wherein the baffle 161 is disposed within the vent cavity 121 and extends from a side away from the second sidewall 112 toward the second sidewall 112.

The internal circulation drying device 1 utilizes the principle of air expansion and work-applying cooling to condense and dry the water vapor entering the internal circulation drying device 1 from the water tank body 100; the principle that the air is compressed to do work and rise temperature is also utilized to change the dry cold air in the internal circulation drying device 1 into dry hot air, and the dry hot air is discharged into the water tank body 100 to be dried in a circulating mode. The first connecting rod mechanism 13 drives the sliding block 12 to do reciprocating linear motion so as to achieve the purposes of air expansion and compression.

When the slider 12 slides from the direction close to the air inlet pipe 17 toward the air outlet pipe 18, the first baffle plate 144 of the second link mechanism 14, the second baffle plate 154 of the third link mechanism 15, and the partition plate 161 of the turnover mechanism 16 are all in the closed state, at this time, the moist water vapor between the first baffle plate 144 and the partition plate 161 performs work expansion and cooling to be dry cold air, and at the same time, the dry cold air between the second baffle plate 154 and the partition plate 161 is heated by compression temperature to be dry hot air, the first return spring 145 of the second link mechanism 14 is stretched, and the second return spring 155 of the third link mechanism 15 is compressed. After the sliding block 12 slides for a certain distance, the air cooling and heating operations of the two sides of the partition 161 (the space between the partition 161 and the first baffle 144, and the space between the partition 161 and the second baffle 154) are simultaneously completed, at this time, the pushing force of the second pushing spring 153 of the third link mechanism 15 is restored to push the second baffle 154 to rotate and push away through the second pushing rod 152, that is, one side of the second pushing rod 152 connected with the second baffle 154 moves towards the outer end of the second extending cavity 117 connected with the exhaust pipe 18, and the second baffle 154 rotates due to the other side being blocked by the second stopper 158, so that the second extending cavity 117 is opened, at this time, the second restoring spring 155 is compressed, and the existence of the pressure difference enables the hot and dry air between the second baffle 154 and the partition 161 to enter the sink body 100 through the exhaust pipe 18. In the above process, the first directional pin 165 and the second directional pin 16 are always in a closed state, the second positioning column 1612 of the partition board 161 is located in the first guide rail 162, and the third positioning column 1613 is located in the second guide rail 163, so that the third positioning column 1613 of the partition board 161 is prevented from entering the third guide rail 164 to turn over, and the spaces on the two sides of the partition board 161 are communicated.

When the slider 12 of the internal circulation drying device 1 slides from the direction close to the exhaust pipe 18 toward the intake pipe 17, the second shutter 154 of the third link mechanism 15 returns to the closed state under the action of the second return spring 155, and the second stopper 158 allows the second shutter 154 to be normally closed. When the second shutter 154 is closed, the second orientation pin 166 is opened, so that the end of the second guide rail 163 near the second extension chamber 117 communicates with the third guide rail 164, the partition 161 of the turnover mechanism 16 is turned open (turned 90 ° when running to the highest point of the third guide rail 164) by the first guide rail 162 and the third guide rail 164, so that the dry cool air between the first barrier 144 and the partition 161 enters between the partition 161 and the second barrier 154, and after the dry cool air enters, the slide block 12 continues to slide, the partition 161 is turned open (90 deg. when running to the lowest point of the third guide rail 164) by the first guide rail 162 and the third guide rail 164, the septum 161 thus re-closes the vent lumen 121, at which time the first orientation pin 165 opens, such that the end of the second rail 163 adjacent the first elongated cavity 116 is open to the third rail 164 and the partition 161 of the canting mechanism 16 is returned to the second rail 163. Thereafter, the first baffle 144 is pushed away by the reset thrust of the first thrust spring 143 of the second link mechanism 14, that is, one side of the connection moves towards the outer end of the connection between the first extending cavity 116 and the air inlet pipe 17, and the first baffle 144 rotates due to the other side being blocked by the first limiting block 148, so that the first extending cavity 116 is opened, at this time, the first reset spring 145 is compressed, the water vapor in the water tank body 100 enters between the first baffle 144 and the partition plate 161 through the air inlet pipe 17 due to the existence of the pressure difference, and the dry cold air entering before can dry and cool the water vapor.

In the two processes, the air cooling and temperature rising effects are the expansion ratio and the compression ratio, the whole volume of the internal circulation drying device is smaller, the volume of air to be cooled and heated is smaller, and when the compression ratio reaches 9, the temperature of the internal circulation drying device can reach the effect of an air compressor. Assuming that the compression ratio is 7, i.e. the original air V1 needs to be compressed to 1/7V1, the stroke of the slider 12 is 6/7 of the distance between the connection points of the intake pipe 17 and the exhaust pipe 18 with the base 11. For example, the distance between the inlet pipe 17 and the junction of the outlet pipe 18 and the susceptor 11 is 350mm, the stroke of the slider 12 is 300mm, and sufficient cooling and temperature rise can be satisfied.
