The left and right sides of the bottom front side of the controller housing 311 are respectively fixedly connected with connecting plates 318. The tops of the two connecting plates 318 are fixedly connected with vertical plates 319 on one side away from the controller housing 311. The opposite sides of the two vertical plates 319 are fixedly connected with a plurality of horizontal sliding rods 3110. The inner wall of the transmission bin 312 is fixedly connected with a dual-axis motor 314. The left and right output ends of the dual-axis motor 314 extend to the outer sides of the transmission bin 312 respectively. The left and right sides of the wall are fixedly connected with conical teeth 315, the outer walls of the two conical teeth 315 are meshed with the second conical teeth 316, the inner walls of the two second conical teeth 316 are fixedly connected with screw rods 317, the bottoms of the two screw rods 317 are movably connected to the tops of the two screw rod connection bottom blocks 313, the baffle 32 includes a baffle body 321, the outer wall of the baffle body 321 is slidably connected to the opposite sides of the two vertical plates 319 and the controller housing 311, the left and right sides of the baffle body 321 are fixedly connected with baffle side plates 322, the rear sides of the two baffle side plates 322 are fixedly connected with transmission blocks 323, the inner walls of the two transmission blocks 323 are threadedly connected to the outer walls of the screw rods 317, and the front sides of the baffle body 321 are respectively provided with two sets of inclined The filter assembly 33 comprises a plurality of movable rods 331, the inner walls of the plurality of movable rods 331 are respectively slidably connected to the outer walls of the plurality of transverse sliding rods 3110, the rear sides of the plurality of movable rods 331 are fixedly connected to movable rod slide bars 332, the outer walls of the plurality of movable rod slide bars 332 are respectively slidably connected to the inner walls of the two groups of inclined grooves 324 with opposite inclinations, the upper and lower sides of the front sides of the plurality of movable rods 331 are respectively fixedly connected to polyethylene filter screen connection blocks 333, the opposite sides of the plurality of polyethylene filter screen connection blocks 333 are respectively fixedly connected to polyethylene filter screens 334, the air intake and exhaust frames 34 comprise a plurality of air intake and exhaust fan connection frames 341, the tops and bottoms of the plurality of air intake and exhaust fan connection frames 341 are respectively fixedly connected to connection frame connection rods 342,The left and right sides of the two connecting frame connecting rods 342 are respectively fixedly connected to the left and right sides of the rear side of the inner wall of the controller housing 311, and the front side of the inner wall of the multiple intake and exhaust fan connecting frames 341 is fixedly connected with a cross rod 343, and the rear sides of the multiple cross rods 343 are movably connected with fans 344. The intake and exhaust controller 3 and the second intake and exhaust controller 4 have the same structure and face opposite directions;

[0037] When air intake is needed, first start the dual-axis motor 314 so that the dual-axis motor 314 drives the two conical teeth 315 to rotate. Since the conical teeth 315 are meshed with the second conical teeth 316, the rotation of the conical teeth 315 will drive the second conical teeth 316 and the screw rod 317 connected thereto to rotate. The rotation of the screw rod 317 will drive the transmission block 323 to move upward on the screw rod 317. Since the transmission block 323 is fixedly connected to the baffle side plate 322, the baffle body 321 will also move upward. With the movement of the baffle body 321, the front side of the controller housing 311 is no longer blocked by the baffle body 321, so that the front air inlet of the purification door body can be connected to the external environment. The air intake effect is further enhanced through the operation of the fan 344. The baffle body 321 is provided with a plurality of groups of inclined grooves 324 with opposite inclinations. When the baffle body 321 moves upward, the moving rod slide bar 332 will slide in the inclined grooves 324, thereby driving the inclination of the two groups of inclined grooves 324 to push the moving rod slide bar 332 to slide along the inner wall of the inclined grooves 324, thereby driving the moving rod 331 and the polyethylene filter screen 334 connected thereto to move to both sides until the leftmost and rightmost moving rods 331 are attached to the opposite surfaces of the two vertical plates 319, and the polyethylene filter screen 334 is fully unfolded, thereby maximizing the filtering area of ​​the intake air and improving the filtering effect of the intake air. When the air in the external environment passes through the polyethylene filter screen 334, the impurities and particles therein will be effectively filtered, ensuring that the air entering the interior of the purification door body is clean.

[0038] In addition, the intake and exhaust controller 3 and the second intake and exhaust controller 4 have the same structure and are in opposite directions, so that when the purification door body needs to be exhausted, it is only necessary to start the second intake and exhaust controller 4. At this time, the baffle body in the second intake and exhaust controller 4 will move upward to open the exhaust port, so that the gas inside the purification door body can be discharged smoothly.

[0039] like Figure 2 and Fig.10As shown, the door frame 1 includes a door frame body 11, a concave plate 12 is fixedly connected to the bottom of the inner wall of the door frame body 11, a sealing slide plate 13 is slidably connected to the inner wall of the concave plate 12, and the left and right sides of the sealing slide plate 13 are respectively fixedly connected to sealing slide plate bottom blocks 14, and the bottoms of the two sealing slide plate bottom blocks 14 are fixedly connected to springs 16, and the inner walls of the two sealing slide plate bottom blocks 14 are rotatably connected to rotating rods 15, and the sides of the two rotating rods 15 away from the sealing slide plate bottom blocks 14 are rotatably connected to the bottom of the middle part of the inner wall of the concave plate 12, and the bottoms of the two springs 16 are respectively fixedly connected to the left and right sides of the bottom of the inner wall of the concave plate 12, and the outer wall bottom of the sealing slide plate 13 is slidably connected to the top of the inner wall of the concave plate 12;

[0040] When the clean door 2 is closed, the clean door 2 will fit tightly with the door frame 1. At this time, the bottom of the clean door 2 will contact the concave plate 12 in the door frame body 11. As the clean door 2 is further closed, its bottom will push the sealing slide plate 13 to slide downward along the inner wall of the concave plate 12. During the sliding process, the sealing slide plate 13 will compress the spring 16 connected to it. At the same time, through the action of the rotating rod 15, the sealing slide plate 13 can slide smoothly along the inner wall of the concave plate 12, ensuring that no excessive friction or obstruction is generated during the closing process;

[0041] When the cleanroom door 2 is fully closed, the sealing slide plate 13 will be fully compressed in the concave plate 12. At this time, the sealing slide plate 13 is reset and snapped into the inner wall of the bottom sealing groove 24 by the spring 16, so that a tight seal is formed between the cleanroom door 2 and the door frame 1, effectively preventing outside air or impurities from entering the inside of the cleanroom door body through the gap, ensuring the sealing and filtering effect of the cleanroom door body, ensuring that the gas inside the cleanroom door body will not leak into the external environment, and also preventing external impurities and particles from entering the inside of the cleanroom door body;

[0042] In addition, the close fit between the door frame 1 and the cleanroom door 2 not only ensures the sealing performance, but also improves the overall aesthetics. At the same time, due to the coordinated use of the sealing slide plate 13 and the spring 16, the cleanroom door 2 can be closed smoothly and stably, thus avoiding noise and damage caused by friction or obstruction.

[0043] At the same time, the spring 16 also plays a certain buffering role, reducing the impact and noise when the purification door 2 is closed.

[0044] The working principle of the present invention is as follows: when air intake is required, the dual-axis motor 314 is first started, so that the dual-axis motor 314 drives the two conical teeth 315 to rotate. Since the conical teeth 315 are meshed with the second conical teeth 316, the rotation of the conical teeth 315 will drive the second conical teeth 316 and the screw rod 317 connected thereto to rotate, and the rotation of the screw rod 317 will drive the transmission block 323 to move upward on the screw rod 317. Since the transmission block 323 is fixedly connected to the baffle side plate 322, the baffle body 321 will also move upward accordingly. With the movement of the baffle body 321, the front side of the controller housing 311 is no longer blocked by the baffle body 321, so that the front side air inlet of the purification door body can be connected with the external environment, and the operation of the fan 344 further enhances the air intake effect. At the same time, since a plurality of groups of inclined slide grooves 324 with opposite inclinations are provided on the baffle body 321, when the baffle body 321 moves upward, the moving rod slide rod 332 will move in the inclined The sliding groove 324 slides, thereby driving the inclination of the two sets of inclined sliding grooves 324 to push the moving rod sliding rod 332 to slide along the inner wall of the inclined sliding groove 324, thereby driving the moving rod 331 and the polyethylene filter screen 334 connected thereto to move to both sides until the leftmost and rightmost moving rods 331 are in contact with the opposite surfaces of the two vertical plates 319, and the polyethylene filter screen 334 is fully unfolded, thereby maximizing the filtration area of ​​the intake air and improving the filtration effect of the intake air. When the air in the external environment passes through the polyethylene filter screen 334, the impurities and particles therein will be effectively filtered to ensure that the air entering the interior of the purification door body is clean. In addition, the structure of the intake and exhaust controller 3 and the second intake and exhaust controller 4 are the same and in opposite directions, so that when the purification door body needs to be exhausted, it only needs to start the second intake and exhaust controller 4. At this time, the baffle body in the second intake and exhaust controller 4 will move upward to open the exhaust port so that the gas inside the purification door body can be discharged smoothly;

[0045] When the cleanroom door 2 is closed, the cleanroom door 2 will fit tightly with the door frame 1. At this time, the bottom of the cleanroom door 2 will contact the concave plate 12 in the door frame body 11. As the cleanroom door 2 is further closed, its bottom will push the sealing slide plate 13 to slide downward along the inner wall of the concave plate 12. During the sliding process, the sealing slide plate 13 will compress the spring 16 connected to it. At the same time, through the action of the rotating rod 15, the sealing slide plate 13 can slide smoothly along the inner wall of the concave plate 12 to ensure that no excessive friction or obstruction is generated during the closing process. When the cleanroom door 2 is fully closed, the sealing slide plate 13 will be fully compressed in the concave plate 12. At this time, the sealing slide plate 13 is reset by the spring 16 and is stuck in the inner wall of the bottom sealing groove 24, so that A tight seal is formed between the clean room door 2 and the door frame 1, which effectively prevents outside air or impurities from entering the clean room door body through the gap, thereby ensuring the sealing and filtering effect of the clean room door body, ensuring that the gas inside the clean room door body will not leak into the external environment, and also preventing external impurities and particles from entering the clean room door body. In addition, the close fit between the door frame 1 and the clean room door 2 not only ensures the sealing, but also improves the overall aesthetics. At the same time, due to the coordinated use of the sealing slide plate 13 and the spring 16, the clean room door 2 can be closed smoothly and smoothly, avoiding noise and damage caused by friction or obstruction. At the same time, the spring 16 also plays a certain buffering role, reducing the impact and noise when the clean room door 2 is closed.
