The movement of the rack 63 will drive the second gear 52 to rotate, and the rotation of the second gear 52 will drive the transmission rack 62 to move, and the movement of the transmission rack 62 will drive the fixed rods 61 on both sides to slide close to each other, and the movement of the two fixed rods 61 will drive the two closed doors 6 to move close to each other. Due to the limited length of the double-sided rack 63, after the double-sided rack 63 moves to a position where it is not meshed with the first gear 43 and the second gear 52, the closed doors 6 on both sides move to a state of contact with each other, thereby closing the vent 31, and then closing the vent 31 while the folded opaque cloth 8 is folded. After the storage of the device is completed, as shown in the attached Figure 2 As shown, the folded light-proof cloth 8 is in a folded state, the closed door 6 closes the vent 31, the wind detector 72 detects no wind and the ultraviolet lamp 7 is in a closed state; Each double-sided rack 63 is meshed with the second gear 52 and the first gear 43.

A measuring probe 73 and a reference probe 74 are fixedly installed on the upper end of the wind force detector 72. The measuring probe 73 and the reference probe 74 penetrate the inner side wall of the wind slot 34 respectively. When the device is in working state, as shown in the attached Figure 1 As shown, the cabin board 2 is fixed to the top of the wall, and at this time, the vent 31 is in an open state, the HEPA filter and the fan in the filter cabin 3 are started, and ventilation is carried out through the vents 31 on both sides, that is, at this time, the gas in the filter cabin 3 is in a circulating state, and a measuring probe 73 and a reference probe 74 are set at the upper end of the wind detector 72, which are both located on the inner wall of the wind slot 34. When the fan is started and the air flows through the probe, the measuring probe 73 is heated for measurement. The reference probe 74 is used as a reference probe. When there is airflow passing through, the heat of the measuring probe 73 will be taken away by the airflow, and its temperature will change. The instrument can sense the temperature change and thus detect the existence of wind speed. After the wind detector 72 detects the wind speed, it means that the equipment is in working state at this moment. The wind detector 72 can start the ultraviolet lamp 7 through the relay 71 to irradiate and sterilize the space inside the folded opaque cloth 8, thereby realizing that the ultraviolet lamp 7 is automatically turned on for sterilization while the filter and the fan are turned on; A metal bottom plate 82 is fixedly installed at the lower end of the foldable light-proof cloth 8, and four pull ropes 81 are fixedly installed at the upper end of the metal bottom plate 82.

When the user completes the sample processing and does not need to use the device, the device can be folded and stored. The user can start the driving motors 23 on both sides. The starting of the driving motors 23 on both sides will drive the winding rollers 42 on both sides to rotate in opposite directions. When the winding rollers 42 rotate, the pull ropes 81 will be rolled up. The rolling of the pull ropes 81 will drive the metal bottom plate 82 to move upward. The upward movement of the metal bottom plate 82 will drive the foldable light-proof cloth 8 to fold, thereby realizing the folding of the foldable light-proof cloth 8 and reducing the space occupied by the device when it is not in use. Second chains 92 are provided on both side ends of the transparent film 9, and two operating cylinders 91 are provided through the side ends of the transparent film 9. Each second chain 92 is meshed with the first chain 83, and each side end of the second chain 92 is provided with a zipper head 93. After the sample processing is completed, the user can store the device. Before storage, the transparent film 9 can be rolled up first. The user can pull the zipper head 93 to separate the second chain 92 and the first chain 83. After separation, the transparent film 9 can be rolled up. An operating cylinder 91 is provided on the transparent film 9. In actual operation, the user can operate the sample by wearing gloves and reaching into the operating cylinder 91 to ensure that the folded opaque cloth 8 and the transparent film 9 cooperate to make the sample processing area a closed space.

[0019] Working principle: In the first step, in the processing of samples, the samples are extremely precious and fragile. During the processing, dust, microorganisms, pollen and other pollutants in the environment may adhere to the surface of the samples or enter the inside of the samples, accelerating the corrosion and deterioration of the samples. Microorganisms may grow on the surface of the samples and secrete acidic substances, causing damage to the sample material. When processing the samples, the samples can be placed on the metal bottom plate 82 in the folded opaque cloth 8 for processing. The filter cabin 3 is provided with a filter and a fan. Before processing, the air can be filtered by the filter in the filter cabin 3. The filter in the filter cabin 3 is a HEPA filter. The HEPA filter can achieve a good filtering efficiency for particles with a particle size of 0.3 microns. Its working principle is based on interception, inertial collision, diffusion effect, etc. When the dust-laden airflow passes through the filter screen of the HEPA filter, the tiny particles are captured due to collision with the fibers and attraction by van der Waals forces, creating a clean operating environment for the samples. In actual processing, the user can wear gloves and extend his hand through the operating tube 91 into the folded opaque cloth 8 to process the sample. The transparent film 9 is made of transparent material, and the state of sample processing can be observed through the transparent film 9.

[0020] The second step is that the device is in working condition, as shown in the attached Figure 1As shown, the cabin board 2 is fixed to the top of the wall, and at this time, the vent 31 is in an open state, the HEPA filter and the fan in the filter cabin 3 are started, and ventilation is carried out through the vents 31 on both sides, that is, at this time, the gas in the filter cabin 3 is in a circulating state, and a measuring probe 73 and a reference probe 74 are set at the upper end of the wind detector 72, which are both located on the inner wall of the wind slot 34. When the fan is started and the air flows through the probe, the measuring probe 73 is heated for measurement. The reference probe 74 is used as a reference probe. When there is airflow passing through, the heat of the measuring probe 73 will be taken away by the airflow, and its temperature will change. The instrument can sense the temperature change and thus detect the existence of wind speed. After the wind detector 72 detects the wind speed, it means that the equipment is in working state at this moment. The wind detector 72 can start the ultraviolet lamp 7 through the relay 71 to irradiate and sterilize the space inside the folded opaque cloth 8, thereby realizing that the ultraviolet lamp 7 is automatically turned on for sterilization while the filter and the fan are turned on; The device is equipped with an ultraviolet lamp 7, a relay 71 and a wind force detector 72. When the device is in working state, the ultraviolet lamp 7 can be started when the measuring probe 73 and the reference probe 74 on the wind force detector 72 detect the wind force of the air flow, thereby realizing the linkage control between the device and the ultraviolet lamp 7 in the working state, and there is no need to manually operate the switch of the ultraviolet lamp 7, thereby improving the working efficiency, reducing the erroneous operation caused by human negligence, and avoiding the phenomenon of forgetting to turn on the ultraviolet lamp 7 during work or forgetting to turn off the ultraviolet lamp 7 after completing the sample processing. When the device is started, the ultraviolet lamp 7 can immediately respond and turn on to ensure the sterilization effect; The third step is that after the sample processing is completed, the user can store the device. Before storing, the transparent film 9 can be rolled up first. The user can pull the zipper head 93 to separate the second chain 92 and the first chain 83. After separation, the transparent film 9 can be rolled up. An operating cylinder 91 is set on the transparent film 9. In actual operation, the user can operate the sample by wearing gloves and reaching into the operating cylinder 91 to ensure that the folded opaque cloth 8 and the transparent film 9 cooperate to make the sample processing area a closed space; The device is provided with a transparent film 9 that is easy to roll up. In the working state, the transparent film 9 can cooperate with the folded opaque cloth 8 to form a relatively closed space, effectively blocking dust, fibers and other tiny particles in the air from entering the operating area, thereby reducing the risk of sample contamination. The transparent film 9 is provided with an operating cylinder 91, which allows the user's hand to easily reach in for operation. The user can flexibly use tools to clean, inspect, repair and other operations on the sample, and the transparent film 9 is easy to roll up. The second chain 92 and the first chain 83 cooperate to achieve rapid rolling of the transparent film 9, and the operation is simple and fast. In the fourth step, when the user has finished processing the sample and does not need to use the device anymore, the user can fold and store the device. The user can start the drive motors 23 on both sides. The start of the drive motors 23 on both sides will drive the winding rollers 42 on both sides to rotate in opposite directions. When the winding rollers 42 rotate, the pull rope 81 will be rolled up. The rolling of the pull rope 81 will drive the metal bottom plate 82 to move upward. The upward movement of the metal bottom plate 82 will drive the folded light-proof cloth 8 to fold, thereby realizing the folding of the folded light-proof cloth 8 and reducing the space occupied by the device when it is not in use. The device is provided with a foldable light-proof cloth 8. The foldable light-proof cloth 8 can be folded and stored when not in use, thereby reducing the space occupied by the device. In the existing sample processing space, the existing equipment occupies a large space when not in use, resulting in low space utilization. Compared with the traditional fixed structure operating table, the device optimizes the space utilization of the sample processing area, and the storage operation is convenient, which can be achieved by opening and closing the drive motor 23, and the operation is convenient, and can achieve rapid storage and reset, and is flexible to use. In the fifth step, when the winding rollers 42 on both sides rotate, the first gear 43 is driven to rotate, and the rotation of the first gear 43 drives the double-sided rack 63 to move, and the movement of the double-sided rack 63 drives the second gear 52 to rotate, and the rotation of the second gear 52 drives the transmission rack 62 to move, and the movement of the transmission rack 62 drives the fixed rods 61 on both sides to slide close to each other, and the movement of the two fixed rods 61 drives the two closed doors 6 to move close to each other. Due to the limited length of the double-sided rack 63, after the double-sided rack 63 moves to a position where it is not meshed with the first gear 43 and the second gear 52, the closed doors 6 on both sides move to a state of contact with each other, thereby achieving the closure of the vent 31, and then achieving the closure of the vent 31 while the folded opaque cloth 8 is folded. After the storage of the device is completed, as shown in the attached Figure 2 As shown, the folded light-proof cloth 8 is in a folded state, the closed door 6 closes the vent 31, the wind detector 72 detects no wind and the ultraviolet lamp 7 is in a closed state; The device is provided with two movable and adjustable closed doors 6. When the user folds and stores the device, the closed doors 6 on both sides can be driven to move closer to each other to close the vent 31, thereby preventing dust, fibers and other tiny particles from easily entering the filter cabin 3 through the vent 31. When the device is reset, the closed doors 6 can also be driven to move away from each other, so that the vent 31 is in an open state, thereby allowing the filter and the fan to work. The device is flexible to use and has a better protection effect on the device after folding. The device cooperates with the winding roller 42, the first gear 43, the double-sided rack 63, the second gear 52 and the transmission rack 62, so that the vent 31 can be closed while the folded opaque cloth 8 is folded, thereby realizing integrated operation. After the user completes the folding and storage of the folded opaque cloth 8, there is no need to close the vent 31 separately, which simplifies the workflow and eliminates the need for additional manual operations, thereby improving the efficiency of equipment storage and processing, saving manpower and avoiding the phenomenon of negligence in manual processing and forgetting to close the vent 31.
