Description

Technical Field

[0001] This invention relates to the field of smart grid technology, and more specifically to a communication power supply cabinet that facilitates heat dissipation. Background Technology

[0002] With the rapid development of communication technology, communication power supply cabinets, as an important component of communication infrastructure, play a crucial role in ensuring the normal operation of communication networks through their stability and reliability. Because power supply cabinets integrate a large number of electronic devices, such as environmental monitoring equipment, remote data reading devices, remote visualization devices, and batteries, these devices generate a significant amount of heat during operation. Poor heat dissipation can lead to decreased equipment performance and even malfunctions.

[0003] To address the aforementioned issues, several existing technologies exist that can improve the heat dissipation performance of the cabinet. For example, patent publication number CN211605858U primarily utilizes a cooling motor to drive a cooling fan, generating airflow that allows cool air to enter the cabinet through the air inlet. The airflow then passes through a dust filter and is expelled from the cabinet via the vents, achieving heat dissipation. However, analysis reveals a drawback: this technology cannot dehumidify the air entering the cabinet through the vents. During heavy rainstorms, the high humidity and high moisture content in the air entering the cabinet can damage electronic components and even paralyze the entire power grid. Therefore, this invention provides a communication power cabinet that automatically dehumidifies the air entering the cabinet without affecting its heat dissipation. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a communication power supply cabinet that facilitates heat dissipation, thereby solving the technical problem that the high moisture content in the air entering the cabinet when the ambient humidity is high can damage the electronic components inside the cabinet.

[0005] The objective of this invention can be achieved through the following technical solutions: A communication power supply cabinet with convenient heat dissipation includes: The cabinet has a heat dissipation hole group on its side wall, which includes an air inlet hole group and an air outlet hole group. A box body is fixed inside the cabinet body and aligned with the heat dissipation hole group. The position on the box body aligned with the air inlet hole group is a dehumidification position, and an air inlet pipe connected to the air inlet hole group is provided on the dehumidification position. An exhaust pipe connected to the air outlet hole group is also provided on the box body, and a pressure pump is provided on the exhaust pipe. A rotating wheel, rotatably mounted within a housing, has several circumferentially arranged positioning discs. Frames for mounting dehumidifying cotton are fixed to these positioning discs. The rotating wheel is driven by a drive assembly to rotate intermittently, and each time it stops, the air intake pipe aligns with a dehumidifying cotton piece on one of the frames. Each frame has a sliding lifting plate with dehumidifying cotton on it. The bottom of the lifting plate is connected to the frame via an elastic element. The frame is equipped with a limit switch, and the position of the limit switch interferes with a point path of the lifting plate. The limit switch is connected to the drive assembly. When the dehumidifying cotton aligned with the air inlet pipe absorbs water, its weight gradually increases, which drives the lifting plate to gradually descend until the dehumidifying cotton absorbs water to the point where its weight reaches a threshold. At this time, the lifting plate triggers the limit switch, and the drive assembly starts to drive the rotating wheel to rotate once. When the rotating wheel stops, the dehumidifying cotton adjacent to the current dehumidifying cotton rotates to be aligned with the air inlet pipe.

[0006] As a further aspect of the present invention, the number of heat dissipation hole groups is at least one.

[0007] As a further aspect of the present invention: the position on the box body aligned with the air outlet group is a drying position, and an exhaust pipe connected to the air outlet group is provided on the drying position.

[0008] As a further embodiment of the present invention: an air collecting pipe is respectively provided in the dehumidification position and the drying position of the box body. One end of the air collecting pipe in the dehumidification position is connected to the air inlet group, and the other end abuts against the rotating wheel, and the two are slidably engaged. One end of the air collecting pipe in the drying position is connected to the air outlet group, and the other end abuts against the rotating wheel, and the two are slidably engaged. The two air collecting pipes are coaxially arranged with the air inlet pipe and the air outlet pipe, respectively.

[0009] As a further aspect of the present invention: the dehumidification position and the drying position are symmetrically arranged, and a squeezing position is provided on the box body at a position between the dehumidification position and the drying position. Each time the rotating wheel stops rotating, the squeezing position is aligned with the dehumidifying cotton on a frame. The squeezing position is provided with a squeezing component.

[0010] As a further aspect of the present invention: a U-shaped frame for installing dehumidifying cotton is fixed on the lifting plate, and the open end of the U-shaped frame is connected to the lifting plate. A movable rod is slidably installed on the open end of the U-shaped frame, and a second magnetic component is fixed on the movable rod. A first magnetic component is fixed on the end of the U-shaped frame away from the movable rod, and the magnetism of the first magnetic component and the magnetism of the second magnetic component repel each other. A fixed column is fixed on the movable rod. When the frame rotates to the squeezing position, the fixed column triggers the squeezing assembly to squeeze the dehumidifying cotton.

[0011] As a further aspect of the present invention: both the intake pipe and the exhaust pipe are hinged with sealing plates, and the sealing plates are elastically connected to the pipe walls of the intake pipe and the exhaust pipe, and the position of the sealing plates interferes with the movement path of the fixed column.

[0012] As a further aspect of the present invention: the extrusion assembly includes a push plate slidably mounted on the box body and a push column fixed on the positioning plate. The push plate is elastically connected to the box body and is connected to the wedge block via a connecting rod. The position of the wedge block interferes with the movement path of the push column. When the push column rotates with the positioning plate to contact the wedge block, the push plate abuts against the fixed column. Subsequently, the push column continues to rotate with the positioning plate, and the push column moves along the inclined surface of the wedge block and pushes the wedge block to move vertically. The push plate moves vertically synchronously. During this process, the fixed column is blocked and cannot continue to move horizontally. The movable rod slides relative to the U-shaped frame, and the movable rod moves towards the direction of the first magnetic component, so the dehumidifying cotton is squeezed and folded.

[0013] As a further aspect of the present invention: a collection box is provided on the box body, and a squeezing position is provided inside the collection box. A sealing element is provided at the connection between the collection box and the box body. The collection box is connected to the water cooling pipe inside the cabinet through a connecting pipe, and a one-way valve is provided on the connecting pipe.

[0014] The beneficial effects of this invention are: (1) In this invention, the airflow passes through the air inlet group to dehumidify the dehumidifying cotton, and then enters the cabinet through the air inlet pipe. After absorbing the heat in the cabinet, it passes through the exhaust pipe and then through the air outlet group to dissipate heat from the cabinet. It can also automatically dehumidify the air entering the cabinet. During this process, the weight of the dehumidifying cotton gradually increases when it absorbs water, and the lifting plate gradually decreases, causing the elastic element to gradually compress. When the dehumidifying cotton absorbs water to the point where its weight reaches the threshold, the lifting plate descends to trigger the limit switch, and the drive component starts to drive the rotating wheel to rotate once to replace the dehumidifying cotton aligned with the air inlet pipe. The replacement time of the dehumidifying cotton can be adaptively controlled according to the water absorption degree of the dehumidifying cotton. When the dehumidifying cotton absorbs water to the maximum state, a new dry dehumidifying cotton is automatically replaced at the air inlet group to avoid the problem that the dehumidifying cotton cannot dry the airflow after it is saturated with water, and that the airflow entering the cabinet after passing through it will have a large humidity, which will damage the electronic components in the cabinet. (2) In this invention, when the dehumidifying cotton absorbs water and becomes damp in the dehumidification position, it will be transferred to the squeezing position. The squeezing component will squeeze the dehumidifying cotton to squeeze out the absorbed water. Then it will be transferred to the drying position and dried by the airflow that absorbs heat and is pre-discharged. Then it will be transferred back to the dehumidification position for recycling, reducing costs and achieving the functions of green environmental protection and energy saving. (3) In this invention, the water squeezed out after the extrusion component is applied is collected in the collection box and fed into the water cooling pipe to help dissipate heat from the cabinet. This can make full use of the dehumidified water and improve the energy efficiency of the communication power cabinet. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-7 As shown, the present invention is a communication power supply cabinet that facilitates heat dissipation, comprising: The cabinet 1 has a heat dissipation hole group 2 on its side wall. The heat dissipation hole group 2 includes an air inlet group and an air outlet group. A box 3 is fixed inside the cabinet 1 and is aligned with the heat dissipation hole group 2. The position on the box 3 that is aligned with the air inlet group is a dehumidification position. An air inlet pipe 4 connected to the air inlet group is provided on the dehumidification position. An exhaust pipe 5 connected to the air outlet group is also provided on the box 3. A pressure pump is provided on the exhaust pipe 5. A rotating wheel 6 is rotatably mounted inside the housing 3, and several circumferentially arranged positioning discs 7 are provided on the rotating wheel 6. A frame 8 for mounting dehumidifying cotton 10 is fixed on each positioning disc 7. The rotating wheel 6 is driven by a drive assembly 13 to rotate intermittently, and each time it stops rotating, the air inlet pipe 4 is aligned with a dehumidifying cotton 10 on one of the frames 8; and A lifting plate 9 is slidably installed in each of the frames 8, and a dehumidifying cotton 10 is provided on the lifting plate 9. The bottom of the lifting plate 9 is connected to the frame 8 through an elastic element 11. A limit switch 12 is provided on the frame 8, and the position of the limit switch 12 interferes with a point path of the lifting plate 9. The limit switch 12 is connected to the drive assembly 13. When the dehumidifying cotton 10 aligned with the air inlet pipe 4 absorbs water, its weight gradually increases, which drives the lifting plate 9 to gradually descend until the dehumidifying cotton 10 absorbs water to the point where its weight reaches a threshold. At this time, the lifting plate 9 triggers the limit switch 12, and the drive assembly 13 starts to drive the rotating wheel 6 to rotate once. When the rotating wheel 6 stops rotating, the dehumidifying cotton 10 adjacent to the dehumidifying cotton 10 rotates to be aligned with the air inlet pipe 4.

[0020] In one embodiment, the drive assembly 13 includes a motor and an encoder connected to the motor. The encoder is connected to the limit switch 12. Of course, the drive assembly 13 can also be other structural components capable of intermittent rotation, which is not specifically limited here. The positioning disk 7 and the rotating wheel 6 are detachably connected, which can be assembled by snap-fit ​​or by bolt connection, which is not specifically limited here. The elastic element 11 can be the spring shown in Figure 5, or it can be replaced by other elastic components, such as silicone pillars, spring sheets, etc., which are not specifically limited in this embodiment. The pressure pump, the limit switch 12 and the drive assembly 13 are all connected to an external controller. The pressure pump, the limit switch 12 and the external controller are all prior art. This application does not improve them. Therefore, it is not necessary to disclose their specific mechanical structure and circuit structure, which does not affect the integrity of this application.

[0021] In practical applications, the initial state of this embodiment is as follows: Figure 3As shown, at this time, a dehumidifying cotton 10 is aligned with the air inlet pipe 4; the airflow through the air inlet group passes through the dehumidifying cotton 10 for dehumidification, and then enters the cabinet 1 through the air inlet pipe 4. After absorbing the heat inside the cabinet 1, it is discharged through the exhaust pipe 5 and the air outlet group to achieve heat dissipation for the cabinet 1 and automatically dehumidify the air entering the cabinet 1. During this process, as the dehumidifying cotton 10 absorbs water, its weight gradually increases, and the lifting plate 9 gradually decreases, causing the elastic element 11 to gradually compress. When the dehumidifying cotton 10 absorbs water to the point where its weight reaches a threshold, the lifting plate 9 stops. When the plate 9 descends to trigger the limit switch 12, the drive assembly 13 starts and drives the wheel 6 to rotate once to replace the dehumidifying cotton 10 aligned with the air inlet pipe 4. It can adaptively control the replacement time of the dehumidifying cotton 10 according to its water absorption level. When the dehumidifying cotton 10 absorbs water to its maximum state, it automatically replaces it with a new dry dehumidifying cotton 10 at the air inlet group to avoid the problem that the dehumidifying cotton 10 cannot dry the airflow after it is saturated with water, which would also lead to the airflow entering the cabinet 1 with high humidity and damage to the electronic components inside the cabinet 1.

[0022] like Figures 1-2 As shown, in a preferred embodiment of the present invention, the number of heat dissipation hole groups 2 is at least one.

[0023] In practical applications, each heat dissipation hole group 2 is provided with a box 3, which can ensure the efficient heat dissipation and ventilation performance of the cabinet 1.

[0024] like Figures 2-6 As shown, in a preferred embodiment of the present invention, the position on the box 3 that is aligned with the air outlet group is the drying position, and the drying position is provided with an exhaust pipe 5 connected to the air outlet group.

[0025] In one embodiment, the housing 3 is provided with a gas collecting pipe 26 in the dehumidification position and the drying position respectively. One end of the gas collecting pipe 26 in the dehumidification position is connected to the air inlet group, and the other end abuts against the rotating wheel 6, and the two are slidably engaged. One end of the gas collecting pipe 26 in the drying position is connected to the air outlet group, and the other end abuts against the rotating wheel 6, and the two are slidably engaged. The two gas collecting pipes 26 are coaxially arranged with the air inlet pipe 4 and the exhaust pipe 5 respectively.

[0026] In practical applications, the air collecting pipe 26 can collect airflow into the air inlet pipe 4 or through the air outlet group, avoiding the problem of the heat dissipation path of the cabinet 1 being blocked due to the dehumidification structure, which would lead to a decrease in heat dissipation performance. It can also use the airflow after absorbing heat to dry the dehumidifying cotton 10 after it absorbs water. By reusing the heat, the dehumidifying cotton 10 can be recycled, which can improve the service life of the communication power supply cabinet and reduce costs, thus achieving green, environmentally friendly and energy-saving functions.

[0027] like Figures 2-9As shown, in a preferred embodiment of the present invention, the dehumidification position and the drying position are symmetrically arranged, and a squeezing position is provided on the box body 3 at the position between the dehumidification position and the drying position. Each time the rotating wheel 6 stops rotating, the squeezing position is aligned with the dehumidifying cotton 10 on a frame 8. The squeezing position is provided with a squeezing component.

[0028] In practical applications, this embodiment uses... Figure 4 As shown in the example, the rotating wheel 6 is equipped with four positioning discs 7. The dehumidification position is on the left side of the box body 3, the drying position is on the right side of the box body 3, and the squeezing position is on the lower side of the box body 3. When the dehumidifying cotton 10 absorbs water and becomes damp in the dehumidification position, it will move to the squeezing position. The squeezing component will squeeze the dehumidifying cotton 10 to squeeze out the absorbed water. Then it will move to the drying position and be dried by the airflow that absorbs heat and is pre-discharged. Then it will move back to the dehumidification position for recycling.

[0029] like Figures 3-9 As shown, in a preferred embodiment of the present invention, a U-shaped frame 14 for installing dehumidifying cotton 10 is fixed on the lifting plate 9, and the open end of the U-shaped frame 14 is connected to the lifting plate 9. A movable rod 15 is slidably installed on the open end of the U-shaped frame 14, and a second magnetic element 17 is fixed on the movable rod 15. A first magnetic element 16 is fixed on the end of the U-shaped frame 14 away from the movable rod 15, and the magnetism of the first magnetic element 16 is repelled by the magnetism of the second magnetic element 17. A fixing post 18 is fixed on the movable rod 15. When the frame 8 rotates to the squeezing position, the fixing post 18 triggers the squeezing assembly to squeeze the dehumidifying cotton 10.

[0030] In one embodiment, the U-shaped frame 14 and the lifting plate 9 are respectively installed at both ends of the dehumidifying cotton 10, and both are detachable connections. Specifically, they can be assembled by snap-fit ​​or bolted, which will not be elaborated here. The first magnetic component 16 and the second magnetic component 17 can be magnetic blocks or electromagnetic modules, which will not be specifically limited here.

[0031] In practical application, after the two ends of the dehumidifying cotton 10 are respectively installed on the U-shaped frame 14 and the lifting plate 9, the magnetic repulsion makes the distance between the first magnetic component 16 and the lifting plate 9 the largest. At this time, the dehumidifying cotton 10 is in an extended state. When it is aligned with the air inlet pipe 4, it can dehumidify the air before it enters the air inlet pipe 4. When the frame 8 rotates to the squeezing position, the fixed column 18 triggers the squeezing assembly to squeeze the dehumidifying cotton 10 to squeeze out the water in the dehumidifying cotton 10 after it has absorbed water.

[0032] like Figures 3-9 As shown, in a preferred embodiment of the present invention, both the intake pipe 4 and the exhaust pipe 5 are hinged with a sealing plate 19, and the sealing plate 19 is elastically connected to the pipe wall of the intake pipe 4 and the exhaust pipe 5. The position of the sealing plate 19 interferes with the movement path of the fixed column 18.

[0033] In one embodiment, the sealing plates 19 can be connected to the walls of the intake pipe 4 and the exhaust pipe 5 by springs or by spring sheets, which will not be described in detail here; the intake pipe 4 and the exhaust pipe 5 are respectively provided with two sealing plates 19, and according to the rotation direction of the rotating wheel 6, the two sealing plates 19 are respectively provided on the outer side of the pipe wall and the inner side of the pipe wall.

[0034] In practical applications, this embodiment uses... Figure 5 Taking the direction shown as an example, if the rotating wheel 6 rotates counterclockwise, when the positioning disk 7 is in the dehumidification position, the fixing post 18 passes through the top of the air intake pipe 4. The sealing plate 19 here is set inside the pipe wall of the air intake pipe 4. When the fixing post 18 passes through the pipe wall at the top of the air intake pipe 4, it drives the sealing plate 19 to flip. After rotating away, the sealing plate 19 returns to its original position under the elastic action, and re-closes the pipe wall at the top of the air intake pipe 4. When the positioning disk 7 is in the dehumidification position, the fixing post 18 passes through the bottom of the air intake pipe 4. The sealing plate 19 here is set outside the pipe wall of the air intake pipe 4. When the fixing post 18 passes through the bottom wall of the intake pipe 4, it causes the sealing plate 19 to flip. After it rotates away, the sealing plate 19 resets under the elastic action and closes the bottom wall of the intake pipe 4 again. Similarly, in the drying position on the other side of the box 3, the sealing plate 19 at the bottom of the exhaust pipe 5 is located inside its pipe wall, and the sealing plate 19 at the top of the exhaust pipe 5 is located inside its pipe wall. When the positioning plate 7 rotates into the drying position, the fixing post 18 passes through the bottom of the exhaust pipe 5, and when the positioning plate 7 rotates into the drying position, the fixing post 18 passes through the top of the exhaust pipe 5.

[0035] like Figures 3-9 As shown, in a preferred embodiment of the present invention, the extrusion assembly includes a push plate 22 slidably mounted on the box body 3 and a push column 25 fixed on the positioning disk 7. The push plate 22 is elastically connected to the box body 3, and the push plate 22 is connected to the wedge block 24 through a connecting rod 23. The position of the wedge block 24 interferes with the movement path of the push column 25. When the push column 25 rotates with the positioning disk 7 to contact the wedge block 24, the push plate 22 abuts against the fixed column 18. Then the push column 25 continues to rotate with the positioning disk 7, and the push column 25 moves along the inclined surface of the wedge block 24 and pushes the wedge block 24 to move vertically. The push plate 22 moves vertically in sync. During this process, the fixed column 18 is blocked and cannot continue to move horizontally. The movable rod 15 slides relative to the U-shaped frame 14, and the movable rod 15 moves toward the direction of the first magnetic component 16, and the dehumidifying cotton 10 is squeezed and folded.

[0036] In one embodiment, the push plate 22 and the box 3 can be connected by a spring or by a spring sheet, which will not be described in detail here; the two ends of the movable rod 15 are connected to the U-shaped frame 14 by rubber blocks.

[0037] In practical applications, this embodiment uses... Figure 4 Taking the direction shown as an example, the rotating wheel 6 is equipped with four positioning discs 7. The dehumidification position is on the left side of the box body 3, the drying position is on the right side of the box body 3, and the squeezing position is on the lower side of the box body 3. When the dehumidifying cotton 10 absorbs water and becomes damp in the dehumidification position, it will rotate towards the squeezing position. During this process, when the pushing column 25 rotates with the positioning disc 7 until it contacts the wedge block 24, the push plate 22 abuts against the fixed column 18 (e.g., Figure 8 As shown), the push column 25 then continues to rotate with the positioning disk 7, causing the push column 25 to move along the inclined surface of the wedge block 24 and push the wedge block 24 down. The push plate 22 then descends synchronously. During this process, the fixed column 18 is blocked and cannot move further to the right. Therefore, relative sliding occurs between the movable rod 15 and the U-shaped frame 14, and the movable rod 15 moves towards the first magnetic component 16. This causes the dehumidifying cotton 10 to be squeezed and folded (as shown). Figure 9 As shown), this completes the squeezing out of the water from the dehumidifying cotton 10 after absorption, thereby accelerating the drying of the dehumidifying cotton 10 and facilitating its recycling; when the rotating wheel 6 stops rotating, the pushing column 25 contacts the highest point of the inclined surface of the wedge block 24, but the two do not separate (as shown). Figure 9 As shown), at this time, the push plate 22 descends to its highest point and abuts against the fixed column 18. When the rotating wheel 6 starts to rotate again, the push column 25 slides relative to the top of the wedge block 24 and gradually slides away from the wedge block 24. At the same time, after the push plate 22 descends slightly, the fixed column 18 slides relative to the top of the push plate 22 and gradually slides away from the push plate 22. Then, under the action of magnetic repulsion, the movable rod 15 is reset, and the squeezed dehumidifying cotton 10 can return to its extended state. At the same time, under the action of elasticity, the wedge block 24 is reset, ready to contact the next push column 25.

[0038] like Figures 3-9 As shown, in a preferred embodiment of the present invention, a collection box 20 is provided on the box body 3, and a squeezing position is provided inside the collection box 20. A sealing element is provided at the connection between the collection box 20 and the box body 3. The collection box 20 is connected to the water cooling pipe in the cabinet 1 through a connecting pipe 21, and a one-way valve is provided on the connecting pipe 21.

[0039] In one embodiment, the sealing element can be a rubber strip or other structural components with sealing performance, without specific limitations; the water-cooling pipe is laid out against the inner wall of the cabinet 1 and connected to the external liquid tank; the water-cooling pipe is prior art, and this application has not improved it, therefore, it is not necessary to disclose its specific mechanical structure and circuit structure, and it does not affect the integrity of this application.

[0040] In practical application, the squeezing component is located inside the collection box 20. The water squeezed out by the squeezing component is collected in the collection box 20 and flows into the water cooling pipe to help dissipate heat from the cabinet 1. This can make full use of the dehumidified water and improve the energy efficiency of the communication power cabinet.

[0041] Working principle of the invention: The above embodiments of the invention provide a communication power cabinet that facilitates heat dissipation. Airflow passes through the air inlet group and dehumidifies the dehumidifying cotton 10. Then, it enters the cabinet 1 through the air inlet pipe 4, absorbs heat from the cabinet 1, and is discharged through the air outlet group via the exhaust pipe 5. This achieves heat dissipation for the cabinet 1 and automatically dehumidifies the air entering the cabinet 1. During this process, as the dehumidifying cotton 10 absorbs water, its weight gradually increases, causing the lifting plate 9 to gradually decrease, thus compressing the elastic element 11. When the dehumidifying cotton 10 absorbs water to its weight... When the threshold is reached, the lifting plate 9 descends to trigger the limit switch 12, and the drive component 13 starts to drive the rotating wheel 6 to rotate once to replace the dehumidifying cotton 10 aligned with the air inlet pipe 4. It can adaptively control the replacement time of the dehumidifying cotton 10 according to the water absorption degree of the dehumidifying cotton 10. When the dehumidifying cotton 10 absorbs water to the maximum state, it automatically replaces the new dry dehumidifying cotton 10 to the air inlet group, so as to avoid the problem that the dehumidifying cotton 10 cannot dry the airflow after it is saturated with water, and will also cause the airflow entering the cabinet 1 to have high humidity, which will damage the electronic components inside the cabinet 1.

[0042] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.

When the rotating wheel (6) stops rotating, the dehumidifying cotton (10) adjacent to the dehumidifying cotton (10) rotates to be aligned with the air inlet pipe (4). The position on the box (3) aligned with the air outlet group is the drying position, and an exhaust pipe (5) connected to the air outlet group is provided on the drying position. The dehumidification position and the drying position are symmetrically arranged, and a squeezing position is provided on the box body (3) between the dehumidification position and the drying position. When the rotating wheel (6) stops rotating each time, the squeezing position is aligned with the dehumidifying cotton (10) on a frame (8). The squeezing position is provided with a squeezing component. A U-shaped frame (14) for installing dehumidifying cotton (10) is fixed on the lifting plate (9), and the open end of the U-shaped frame (14) is connected to the lifting plate (9). A movable rod (15) is slidably installed on the open end of the U-shaped frame (14), and a second magnetic component (17) is fixed on the movable rod (15). A first magnetic component (16) is fixed on the end of the U-shaped frame (14) away from the movable rod (15), and the magnetism of the first magnetic component (16) and the magnetism of the second magnetic component (17) are repulsive. A fixed column (18) is fixed on the movable rod (15). When the frame (8) rotates to the squeezing position, the fixed column (18) triggers the squeezing assembly to squeeze the dehumidifying cotton (10). The extrusion assembly includes a push plate (22) slidably mounted on the box body (3) and a push column (25) fixed on the positioning plate (7). The push plate (22) is elastically connected to the box body (3), and the push plate (22) is connected to the wedge block (24) through a connecting rod (23). The position of the wedge block (24) interferes with the movement path of the push column (25). When the push column (25) rotates with the positioning plate (7) to contact the wedge block (24), the push plate (22) and the fixed column (1) are connected. 8) Upon contact, the push column (25) continues to rotate with the positioning plate (7), and the push column (25) moves along the inclined surface of the wedge block (24) and pushes the wedge block (24) to move vertically. The push plate (22) moves vertically in sync. During this process, the fixed column (18) is blocked and cannot continue to move horizontally. The movable rod (15) slides relative to the U-shaped frame (14), and the movable rod (15) moves towards the first magnetic component (16), and the dehumidifying cotton (10) is squeezed and folded.
