Description

Technical Field

[0001] This invention relates to the field of variable frequency starter cabinet technology, and in particular to an intelligent high-voltage variable frequency starter cabinet with moisture-proof and dehumidification functions. Background Technology

[0002] A frequency converter (VFD) is a power control device that uses frequency conversion technology and microelectronics to control an AC motor by changing the frequency of its power supply. A VFD mainly consists of a rectification unit (AC to DC), a filter, an inverter (DC to AC), a braking unit, a drive unit, a detection unit, and a microprocessor unit. The VFD adjusts the voltage and frequency of the output power supply by switching its internal IGBTs, providing the required power voltage according to the actual needs of the motor, thereby achieving energy saving and speed regulation. In addition, VFDs have many protection functions, such as overcurrent, overvoltage, and overload protection. With the continuous improvement of industrial automation, VFDs have been widely used.

[0003] A search revealed that patent No. 202022361121.2 discloses "an intelligent high-voltage variable frequency starter cabinet with self-maintenance function", which includes a cabinet. A power device is fixedly connected to the right side wall of the cabinet. A rotating shaft extending into the cabinet is fixedly connected to the output shaft of the power device. Two top blocks are sleeved on the outside of the rotating shaft and located inside the cabinet. Fixing blocks are fixedly connected to the left and right side walls inside the cabinet. Movable rods extending below the fixing blocks and in contact with the top blocks are inserted into the top of the fixing blocks.

[0004] However, when the aforementioned starter cabinet is in use, it simply allows humid air from the outside to enter by blocking the exhaust vent with a baffle. This method cannot absorb the moisture in the humid air, and the moisture in the humid air will still directly enter the starter cabinet from the exhaust vent, resulting in moisture damage to the internal components of the starter cabinet. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that the existing technology simply uses the size of the baffle to block the exhaust port to allow the outside humid air to enter. This method cannot absorb the moisture in the humid air, and the moisture in the humid air will still directly enter the starter cabinet from the exhaust port, resulting in the damage of the internal components of the starter cabinet due to moisture. Therefore, this invention proposes an intelligent high-voltage frequency converter starter cabinet with moisture-proof and dehumidification functions.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A smart high-voltage variable frequency starter cabinet with moisture-proof and dehumidification functions includes a cabinet body, and an exhaust pipe connected to the inside of the cabinet body is provided at the right end of the cabinet body. It also includes a moisture blocking mechanism, which includes two lower flexible water-absorbing blocks that are movably installed through the lower end of the exhaust pipe and are symmetrically arranged on the left and right, and an upper flexible water-absorbing block that is movably installed through the middle of the upper end of the exhaust pipe and is located between the two lower flexible water-absorbing blocks. It is also equipped with an internal dehumidification mechanism, which includes a heat-conducting plate located on the left side of the exhaust pipe and fixedly installed on the inner wall of the cabinet. A collection plate is fixedly installed on the inner wall of the cabinet below the heat-conducting plate.

[0007] Preferably, each of the lower flexible absorbent blocks has a lower connecting seat fixedly installed at its lower end, and the lower connecting seats are fixedly connected to each other by a connecting plate. The upper flexible absorbent block has an upper connecting seat fixedly installed at its upper end.

[0008] Preferably, racks are fixedly installed on the front sides of both the upper and lower connecting seats. The racks are slidably installed on the front end of the exhaust pipe. A gear is rotatably installed on the front end of the exhaust pipe, and the left and right ends of the gear mesh with the two racks respectively. An electric push rod is fixedly installed on the upper end of the upper connecting seat, and the upper end of the electric push rod is fixedly installed on the cabinet.

[0009] Preferably, iron plates are fixedly installed at the ends of the lower flexible absorbent block and the upper flexible absorbent block that are close to each other, and magnetic pressure plates are provided at both the upper and lower ends of the exhaust pipe on the side away from the iron plates. Magnetic rods are fixedly installed at the other ends of the magnetic pressure plates. The magnetic rods are respectively movably installed through the upper and lower ends of the exhaust pipe, and springs are sleeved on the outer sides of the magnetic rods.

[0010] Preferably, a sealing plate is movably installed through the upper left side of the exhaust pipe, and the upper end of the sealing plate is fixedly connected to a magnetic rod.

[0011] Preferably, a magnetic plate is slidably mounted on the upper end of the exhaust pipe, the magnetic plate is located behind the magnetic rod, and a spring is fixedly installed between the magnetic plate and the exhaust pipe.

[0012] Preferably, a top rod is fixedly installed on the upper end of the upper connecting seat, and an inclined plate is fixedly installed on the rear end of the magnetic plate below the top rod.

[0013] Preferably, a through groove is provided at the far end of the lower flexible absorbent block and the middle of the right end of the upper flexible absorbent block, and a connecting rod is movably installed through the through groove. One end of the connecting rod is fixedly connected to the iron plate, and the other end of the connecting rod is movably installed through the lower connecting seat and the upper connecting seat respectively. A spring is sleeved on the outside of the connecting rod, and the two ends of the spring are fixedly connected to the lower connecting seat and the iron plate, or the upper connecting seat and the iron plate respectively.

[0014] Preferably, magnetic plates are attached to the lower sides of the lower flexible absorbent blocks that are close to each other. A rotating shaft is fixedly installed at the front end of the magnetic plate. The front side of the rotating shaft is rotatably mounted on the lower connecting seat. A torsion spring is sleeved on the outer side of the rotating shaft. Magnet blocks are fixedly installed on the magnetic plates on both sides corresponding to the lower end of the exhaust pipe.

[0015] Preferably, a drainage groove is provided on the right end of the cabinet corresponding to the collection plate, and a blocking plate is slidably installed on the right end of the cabinet corresponding to the drainage groove.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, when the external humidity is high, the electric actuator is activated to push the upper connecting seat downwards. The upper connecting seat causes the upper flexible water-absorbing block and its corresponding iron plate to descend, and simultaneously causes the rack fixedly installed with the upper connecting seat to descend, driving the gear to rotate. The gear then drives another rack to rise, which in turn drives the lower connecting seat, the lower flexible water-absorbing block, and its corresponding iron plate to rise. This causes the two lower flexible water-absorbing blocks and the upper flexible water-absorbing block to move relative to each other, adjusting the size of the exhaust pipe. The upper flexible water-absorbing block and the two lower flexible... The absorbent blocks can absorb moisture from the air passing through the exhaust pipe, reducing the entry of external moisture. The upper flexible absorbent block and the two lower flexible absorbent blocks can move in a staggered state, making the internal channel of the exhaust pipe U-shaped. This prevents external moisture from entering the cabinet directly in a straight line, increasing the contact between the moisture and the upper and lower flexible absorbent blocks, thus improving the absorption of moisture and further reducing the entry of moisture. This ensures that the electronic components inside the starter cabinet are not corroded or damaged by moisture.

[0017] 2. In this invention, when the upper flexible absorbent block and the two lower flexible absorbent blocks absorb a large amount of moisture, the upper connecting seat can be pushed down by the electric push rod. The upper connecting seat drives the top rod to descend synchronously. The top rod contacts and squeezes the inclined plate, causing the inclined plate to drive the magnetic plate to slide on the exhaust pipe towards the magnetic rod, compressing the second spring. When the magnetic plate moves to the side where the magnetic rods are far apart (the upper and lower sides of the two magnetic rods), under the action of magnetic repulsion, it will push the magnetic rods on both sides to move in a direction closer to each other, which will also drive the magnetic pressure plates on both sides to move in a direction closer to each other synchronously, compressing the first spring. The magnetic pressure plates are set to facilitate the squeezing of the two lower flexible absorbent blocks and the upper flexible absorbent block fixed to the iron plate, squeezing out the moisture absorbed in the two lower flexible absorbent blocks and the upper flexible absorbent blocks, ensuring that the lower flexible absorbent blocks and the upper flexible absorbent blocks can normally absorb moisture in the humidity.

[0018] 3. In this invention, when the upper magnetic rod descends, it also drives the sealing plate to descend synchronously, sealing the inside of the exhaust pipe and preventing water from splashing into the cabinet when the lower and upper flexible water-absorbing blocks are squeezed out.

[0019] 4. In this invention, the iron plate is designed to be firmly attached to the magnetic pressure plate, which ensures that the magnetic pressure plate will not deviate when it squeezes the lower and upper flexible water-absorbing blocks.

[0020] 5. In this invention, the lower connecting seat and the upper connecting seat can provide a supporting force when the lower flexible water-absorbing block and the upper flexible water-absorbing block are squeezed by the magnetic pressure plate, so as to ensure that the lower flexible water-absorbing block and the upper flexible water-absorbing block can be squeezed normally.

[0021] 6. In this invention, when the upper and lower connecting seats drive the lower and upper flexible water-absorbing blocks to move relative to each other to squeeze out water, the lower connecting seats will also move relative to each other. The lower connecting seat will then drive the rotating shaft, magnetic plate, and torsion spring to rise. The magnetic plate will insert into the gap between the lower flexible water-absorbing block and the lower end of the exhaust pipe. The provided magnet will generate a magnetic repulsion force on the magnetic plate, thereby causing the magnetic plate and rotating shaft to rotate downwards from the lower connecting seat towards the lower flexible water-absorbing block, squeezing it. This creates a gap between the two lower flexible water-absorbing blocks at their closest points and the lower end of the exhaust pipe. This allows water to flow out from the gaps on both sides when the upper flexible water-absorbing block is squeezed out, reducing the likelihood of water being reabsorbed by the lower flexible water-absorbing blocks on both sides when the upper flexible water-absorbing block is squeezed out. This improves the quality of water squeezed out by the lower and upper flexible water-absorbing blocks.

[0022] 7. In this invention, the connecting rod, under the action of spring three, provides support for the iron plate. Since the iron plate is fixed to the lower and upper flexible water-absorbing blocks, it stabilizes the lower and upper flexible water-absorbing blocks during lifting and lowering, preventing them from becoming loose. This allows the lower and upper flexible water-absorbing blocks to lift and lower vertically, ensuring that they do not become loose and preventing the internal channel of the exhaust pipe from becoming straight. This also prevents moisture from contacting the lower and upper flexible water-absorbing blocks, thereby improving the absorption efficiency of moisture in the air.

[0023] 8. In this invention, when a small amount of moisture in the air still enters the cabinet, the heat-conducting plate, located inside the cabinet, receives heat generated by the internal components, resulting in a higher surface temperature. When the moisture enters the cabinet from the exhaust pipe, it first comes into contact with the heat-conducting plate located at the exhaust pipe outlet. The moisture in the air is at a lower temperature, while the heat-conducting plate is at a higher temperature. Due to the large temperature difference, the moisture in the air condenses on the surface of the heat-conducting plate and drips onto the collection plate under gravity. The blockage plate is slid open, and the moisture collected inside the collection plate is discharged to the outside through the drain groove, further reducing the amount of moisture entering the cabinet.

The right end of the cabinet body 1 has an exhaust pipe 2 that communicates with the interior of the cabinet body 1. It also includes a moisture-blocking mechanism. The moisture-blocking mechanism includes two lower flexible water-absorbing blocks 3 that are symmetrically arranged and movably installed through the lower end of the exhaust pipe 2, and an upper flexible water-absorbing block 31 that is movably installed through the middle of the upper end of the exhaust pipe 2 and located between the two lower flexible water-absorbing blocks 3. Each lower flexible water-absorbing block 3 has a lower connecting seat 4 fixedly installed at its lower end, and the lower connecting seats 4 are fixedly connected to each other by a connecting plate. The upper flexible water-absorbing block 31 has an upper connecting seat 41 fixedly installed at its upper end. A rack 5 is fixedly installed on the front side of both the base 41 and the lower connecting base 4. The rack 5 is slidably installed on the front end of the exhaust pipe 2. A gear 6 is rotatably installed on the front end of the exhaust pipe 2, and the left and right ends of the gear 6 mesh with the two racks 5 respectively. An electric push rod 7 is fixedly installed on the upper end of the upper connecting base 41. The upper end of the electric push rod 7 is fixedly installed on the cabinet 1. Iron plates 8 are fixedly installed on the ends of the lower flexible water absorption block 3 and the upper flexible water absorption block 31 that are close to each other. Magnetic pressure plates 9 are provided on the upper and lower ends of the exhaust pipe 2 on the side away from the iron plates 8. Magnetic rods 10 are fixedly installed on the other end of the magnetic pressure plates 9. The magnetic rods 10 are movably installed through the upper and lower ends of the exhaust pipe 2 respectively. Furthermore, spring 11 is fitted on the outer side of the magnetic rod 10. A sealing plate 12 is movably installed through the upper left side of the exhaust pipe 2, and the upper end of the sealing plate 12 is fixedly connected to the magnetic rod 10. A magnetic plate 13 is slidably installed on the upper end of the exhaust pipe 2. The magnetic plate 13 is located behind the magnetic rod 10, and spring 14 is fixedly installed between the magnetic plate 13 and the exhaust pipe 2. A top rod 16 is fixedly installed on the upper end of the upper connecting seat 41. An inclined plate 15 is fixedly installed on the rear end of the magnetic plate 13 below the top rod 16. A through groove 17 is opened at the far ends of the lower flexible water-absorbing blocks 3 and the middle of the right end of the upper flexible water-absorbing block 31, and a connecting plate is movably installed through the through groove 17. Rod 18, one end of connecting rod 18 is fixedly connected to iron plate 8, and the other end of connecting rod 18 is movably installed through the lower connecting seat 4 and the upper connecting seat 41 respectively. Spring 3 19 is sleeved on the outside of connecting rod 18. The two ends of spring 3 19 are fixedly connected to the lower connecting seat 4 and iron plate 8, or the upper connecting seat 41 and iron plate 8 respectively. Magnetic plate 20 is attached to the lower side of the lower flexible water-absorbing block 3 at the close side of each other. A rotating shaft 21 is fixedly installed at the front end of magnetic plate 20. The front side of rotating shaft 21 is rotatably installed through the lower connecting seat 4. Torsion spring 22 is sleeved on the outside of rotating shaft 21. Magnet blocks 23 are fixedly installed on the magnetic plate 20 on both sides of the lower end of exhaust pipe 2.

[0028] During operation, when the external humidity is high, the electric actuator 7 is activated to push the upper connecting seat 41 downwards. The upper connecting seat 41 causes the upper flexible water-absorbing block 31 and its corresponding iron plate 8 to descend. Simultaneously, it also causes the rack 5, which is fixedly installed on the upper connecting seat 41, to descend, driving the gear 6 to rotate. The gear 6 then drives another rack 5 to rise, which in turn drives the lower connecting seat 4, the lower flexible water-absorbing block 3, and its corresponding iron plate 8 to rise. This causes the two lower flexible water-absorbing blocks 3 and the upper flexible water-absorbing block 31 to move relative to each other, adjusting the size of the exhaust pipe 2. The upper flexible water-absorbing block 31 and the two lower flexible water-absorbing blocks 3 can absorb moisture from the air passing through the exhaust pipe 2, reducing the entry of external moisture. Furthermore, the upper flexible absorbent block 31 and the two lower flexible absorbent blocks 3 can move into a staggered state. At this time, the internal channel of the exhaust pipe 2 will be U-shaped, preventing external moisture from directly entering the cabinet 1 in a straight line. This increases the contact between the moisture and the upper flexible absorbent block 31 and the two lower flexible absorbent blocks 3, thereby improving the absorption of moisture in the moisture and further reducing the entry of moisture. This ensures that the electronic components inside the starter cabinet are not corroded by moisture. When the upper flexible absorbent block 31 and the two lower flexible absorbent blocks 3 have absorbed a lot of moisture, the upper connecting seat 41 can be pushed down by the electric push rod 7. The upper connecting seat 41 drives the top rod 16 to descend synchronously. The top rod 16 contacts and squeezes the inclined plate 15. This causes the inclined plate 15 to drive the magnetic plate 13 to slide on the exhaust pipe 2 towards the magnetic rod 10, compressing the second spring 14. When the magnetic plate 13 moves to the side where the magnetic rods 10 are far apart (the upper and lower sides of the two magnetic rods 10), under the action of magnetic repulsion, it will push the magnetic rods 10 on both sides to move closer to each other, which will also drive the magnetic pressure plates 9 on both sides to move closer to each other synchronously, compressing the first spring 11. The magnetic pressure plates 9 are designed to squeeze the two lower flexible water-absorbing blocks 3 and the upper flexible water-absorbing blocks 31 fixed to the iron plate 8, squeezing out the water absorbed in the two lower flexible water-absorbing blocks 3 and the upper flexible water-absorbing blocks 31, ensuring that the lower flexible water-absorbing blocks 3 and the upper flexible water-absorbing blocks 31 are squeezed out. It can effectively absorb moisture from the air. When the upper magnetic rod 10 descends, it also drives the sealing plate 12 to descend synchronously, sealing the inside of the exhaust pipe 2. This prevents water from splashing into the cabinet 1 when the lower flexible absorbent block 3 and the upper flexible absorbent block 31 are squeezed out. The iron plate 8 is designed to firmly adhere to the magnetic pressure plate 9, ensuring that the magnetic pressure plate 9 will not deviate when squeezing the lower and upper flexible absorbent blocks 3 and 31. The lower connecting seat 4 and the upper connecting seat 41 provide support when the lower and upper flexible absorbent blocks 3 and 31 are squeezed by the magnetic pressure plate 9, ensuring that the lower and upper flexible absorbent blocks 3 and 31 can be squeezed normally.When the upper connecting seat 41 and the lower connecting seat 4 drive the lower flexible water-absorbing block 3 and the upper flexible water-absorbing block 31 to move relative to each other to squeeze out water, the upper connecting seat 41 and the lower connecting seat 4 will also move relative to each other. The lower connecting seat 4 will drive the rotating shaft 21, the magnetic plate 20 and the torsion spring 22 to rise. The magnetic plate 20 will be inserted into the gap at the connection between the lower flexible water-absorbing block 3 and the lower end of the exhaust pipe 2. The magnet 23 will generate a magnetic repulsion force on the magnetic plate 20, which will drive the magnetic plate 20 and the rotating shaft 21 to rotate on the lower connecting seat 4 towards the lower flexible water-absorbing block 3, squeezing the lower flexible water-absorbing block 3. This will create a gap between the two lower flexible water-absorbing blocks 3 and the lower end of the exhaust pipe 2, which is beneficial for the water to flow out from the gap on both sides when the upper flexible water-absorbing block 31 is squeezed out. This reduces the water being squeezed by the lower flexible water-absorbing blocks on both sides when the upper flexible water-absorbing block 31 is squeezed out. The reabsorption process improves the water extraction quality of the lower flexible absorbent block 3 and the upper flexible absorbent block 31. The connecting rod 18, under the action of the spring 19, supports the iron plate 8. Since the iron plate 8 is fixed to the lower and upper flexible absorbent blocks 3 and 31, it provides stable lifting and lowering for the blocks, preventing them from becoming loose. This ensures the lower and upper flexible absorbent blocks 3 and 31 can lift vertically, preventing them from becoming loose and ensuring the internal channel of the exhaust pipe 2 does not become straight. This also prevents moisture from contacting the lower and upper flexible absorbent blocks 3 and 31, thus improving the absorption efficiency of moisture in the air.

[0029] As an embodiment of the present invention, an internal dehumidification mechanism is also provided. The internal dehumidification mechanism includes a heat-conducting plate 24 disposed on the left side of the exhaust pipe 2 and fixedly installed on the inner wall of the cabinet 1. A collection plate 25 is fixedly installed on the inner wall of the cabinet 1 below the heat-conducting plate 24. A drainage groove 26 is opened at the right end of the cabinet 1 corresponding to the collection plate 25. A blocking plate 27 is slidably installed at the right end of the cabinet 1 corresponding to the drainage groove 26.

[0030] During operation, when a small amount of moisture in the air still enters the cabinet 1, the heat-conducting plate 24, located inside the cabinet 1, receives heat generated by the internal components, resulting in a higher surface temperature. When the moisture enters the cabinet 1 through the exhaust pipe 2, it will first come into contact with the heat-conducting plate 24 located at the outlet of the exhaust pipe 2. The moisture in the air is at a lower temperature, while the heat-conducting plate 24 is at a higher temperature. Due to the large temperature difference, the moisture in the air will condense on the surface of the heat-conducting plate 24 and then drip onto the collection plate 25 under the action of gravity. By sliding open the blocking plate 27, the moisture collected inside the collection plate 25 will be discharged to the outside through the drain trough 26, which further helps to reduce the amount of moisture entering the cabinet 1.

[0031] Working principle: When this invention is in use, when the external humidity is high, the electric actuator 7 is activated to push the upper connecting seat 41 down. The upper connecting seat 41 drives the upper flexible water-absorbing block 31 and the corresponding iron plate 8 down. At the same time, it also drives the rack 5 fixedly installed with the upper connecting seat 41 down, driving the gear 6 to rotate. The gear 6 then drives another rack 5 to rise. The other rack 5 drives the lower connecting seat 4, the lower flexible water-absorbing block 3 and the corresponding iron plate 8 to rise, thereby causing the two lower flexible water-absorbing blocks 3 and the upper flexible water-absorbing block 31 to move relative to each other, thus adjusting the size of the exhaust pipe 2. The upper flexible absorbent block 31 and the two lower flexible absorbent blocks 3 can absorb moisture from the air passing through the exhaust pipe 2, reducing the entry of external moisture. The upper flexible absorbent block 31 and the two lower flexible absorbent blocks 3 can move into a staggered state, so that the internal channel of the exhaust pipe 2 will be U-shaped, preventing external moisture from directly entering the cabinet 1. This increases the contact between the moisture and the upper flexible absorbent block 31 and the two lower flexible absorbent blocks 3, which in turn helps to improve the absorption of moisture from the air, further reducing the entry of moisture and ensuring that the electronic components inside the starter cabinet are not corroded by moisture. When the upper flexible absorbent block 31 and the two lower flexible absorbent blocks 3 absorb a large amount of water, the upper connecting seat 41 can be pushed down by the electric push rod 7. The upper connecting seat 41 drives the top rod 16 to descend synchronously. The top rod 16 contacts and squeezes the inclined plate 15, causing the inclined plate 15 to drive the magnetic plate 13 to slide on the exhaust pipe 2 towards the magnetic rod 10, compressing the second spring 14. When the magnetic plate 13 moves to the side where the magnetic rods 10 are far apart (the upper and lower sides of the two magnetic rods 10), under the action of magnetic repulsion, it will push the magnetic rods 10 on both sides to move closer to each other, which will also drive the magnetic pressure plates 9 on both sides to move closer to each other synchronously, compressing the first spring 11. The magnetic pressure plates 9 are set to facilitate the squeezing of the two lower flexible absorbent blocks 3 and the upper flexible absorbent block 31 fixed to the iron plate 8, and to compress the two lower flexible absorbent blocks 11. The water absorbed by the water block 3 and the upper flexible water-absorbing block 31 is squeezed out, ensuring that the lower flexible water-absorbing block 3 and the upper flexible water-absorbing block 31 can normally absorb the moisture in the humidity. When the upper magnetic rod 10 descends, it will also drive the sealing plate 12 to descend synchronously, sealing the inside of the exhaust pipe 2, avoiding water splashing into the cabinet 1 when the lower flexible water-absorbing block 3 and the upper flexible water-absorbing block 31 are squeezed out. The iron plate 8 is set to firmly adhere to the magnetic pressure plate 9, which can ensure that the magnetic pressure plate 9 will not deviate when squeezing the lower flexible water-absorbing block 3 and the upper flexible water-absorbing block 31. The lower connecting seat 4 and the upper connecting seat 41 can provide a support force when the lower flexible water-absorbing block 3 and the upper flexible water-absorbing block 31 are squeezed by the magnetic pressure plate 9, ensuring that the lower flexible water-absorbing block 3 and the upper flexible water-absorbing block 31 can be squeezed normally. When the upper connecting seat 41 and the lower connecting seat 4 drive the lower flexible water-absorbing block 3 and the upper flexible water-absorbing block 31 to move relative to each other to squeeze out water, the upper connecting seat 41 and the lower connecting seat 4 will also move relative to each other. The lower connecting seat 4 will drive the rotating shaft 21, the magnetic plate 20 and the torsion spring 22 to rise. The magnetic plate 20 will be inserted into the gap at the connection between the lower flexible water-absorbing block 3 and the lower end of the exhaust pipe 2. The magnet 23 will generate a magnetic repulsion force on the magnetic plate 20, which will drive the magnetic plate 20 and the rotating shaft 21 to rotate on the lower connecting seat 4 towards the lower flexible water-absorbing block 3, squeezing the lower flexible water-absorbing block 3. This will create a gap between the two lower flexible water-absorbing blocks 3 and the lower end of the exhaust pipe 2, which is beneficial for the water to flow out from the gap on both sides when the upper flexible water-absorbing block 31 is squeezed out. This reduces the water being squeezed by the lower flexible water-absorbing blocks on both sides when the upper flexible water-absorbing block 31 is squeezed out. The reabsorption process improves the water extraction quality of the lower flexible absorbent block 3 and the upper flexible absorbent block 31. The connecting rod 18, under the action of the spring 19, provides support for the iron plate 8. Since the iron plate 8 is fixed to the lower flexible absorbent block 3 and the upper flexible absorbent block 31, it provides stable lifting and lowering for the lower and upper flexible absorbent blocks 3 and 31, preventing them from becoming loose. This allows the lower and upper flexible absorbent blocks 3 and 31 to lift and lower vertically, ensuring that they do not become loose and preventing the internal channel of the exhaust pipe 2 from becoming straight. This also prevents moisture from coming into contact with the lower and upper flexible absorbent blocks 3 and 31, thereby improving the absorption efficiency of moisture in the air. When a small amount of moisture still enters the cabinet 1, the heat-conducting plate 24, located inside the cabinet 1, receives heat generated by the internal components, resulting in a higher surface temperature. When the moisture enters the cabinet 1 through the exhaust pipe 2, it will first come into contact with the heat-conducting plate 24 located at the outlet of the exhaust pipe 2. The moisture in the air is at a lower temperature, while the heat-conducting plate 24 is at a higher temperature. Due to the large temperature difference, the moisture in the air will condense on the surface of the heat-conducting plate 24 and drip onto the collection plate 25 under the action of gravity. By sliding open the blocking plate 27, the moisture collected inside the collection plate 25 will be discharged to the outside through the drain groove 26, which further helps to reduce the amount of moisture entering the cabinet 1.
