[0001] The invention relates to the technical field of test tube cleaning, and in particular to a high-temperature disinfection cabinet for laboratory test tubes. Background Art

[0002] As a basic tool in medical and chemical experiments, test tubes are widely used and important. They are mainly used to hold chemical solutions and serve as reaction containers for small amounts of reagents. They can also be used to dissolve small amounts of substances, collect gases, or serve as simple gas generating devices. After using ordinary test tubes, they usually need to be cleaned and wiped dry as much as possible, and then placed in a high-temperature disinfection cabinet for sterilization and disinfection to ensure the normal use of the test tubes.

[0003] For example, Application Document 1, Chinese Patent Publication No. CN219896469U, discloses a laboratory glass test tube sterilization device, belonging to the technical field of test tube sterilization cabinets. The device comprises a sterilization tray, the outer surface of which is fixedly connected to equidistantly arranged connecting blocks. Each connecting block is fixedly connected to the side of a first and second fixing block. Each first fixing block is internally secured with a cable tie. The device can secure test tubes of varying diameters as needed.

[0004] As shown in application document 2, Chinese patent publication number CN215740693U, discloses a test tube disinfection cabinet, including a loading cabinet, a first door cover, a loading barrel, a shower head, a second door cover, a support block, a spring, a placement plate, a buffer pad, a second spring, a motor, a fan, a water pump, a condensation box and a placement rack. The loading cabinet is rotatably provided with a first door cover, the top of the loading cabinet is provided with a loading barrel, a plurality of shower heads are provided at the bottom of the loading barrel, a second door cover is rotatably provided at the top of the loading barrel, five support blocks are provided on the upper part of the inner wall of the loading cabinet, the support blocks are arranged horizontally, hooks are rotatably provided between the support blocks, a torsion spring is provided between the hook and the support block, a placement plate is slidably provided in the middle of the loading cabinet, and the shower head allows the disinfectant to be sprayed more evenly on the test tubes to disinfect the test tubes.

[0005] In laboratory scientific research and testing, test tubes are basic and frequently used experimental instruments. The scientificity and efficiency of their disinfection process directly affect the quality and efficiency of the experiment. At present, the mainstream test tube disinfection model generally adopts a centralized processing strategy, that is, experimenters need to collect a certain number of used test tubes in advance, and after accumulating to a suitable scale, they are placed in a disinfection cabinet for high-temperature disinfection. This traditional processing method has significant defects: on the one hand, the centralized collection process will produce a time lag, causing the chemical reagents, biological samples, organic matter and other substances remaining on the inner wall of the test tube after cleaning to dry and solidify during the static period, which will greatly increase the difficulty of subsequent disinfection; second, after the centralized disinfection is completed, a large number of high-temperature test tubes need to be transferred to an external storage area at one time. During this process, the test tubes are exposed to the conventional laboratory environment and are easily attached to microorganisms, dust and other pollutants in the air, resulting in a significant reduction in the disinfection results. Summary of the Invention

[0006] The present invention provides a high-temperature disinfection cabinet for laboratory test tubes, aiming to solve the problem in the related art that the centralized collection process of test tubes will produce a time lag, causing the residual substances on the inner wall of the test tubes after cleaning to dry and solidify during the static period, which will greatly increase the difficulty of subsequent disinfection; a large number of high-temperature test tubes need to be transferred to an external storage area at one time.

The upper end opening of the placement tube is rotatably installed with an opening and closing part through an elastic shaft, and a storage groove is provided on the inner wall of the upper end of the placement tube.

[0015] Preferably, it includes a cabinet, a high-temperature disinfection chamber, a low-temperature storage chamber, and a removal chamber are all arranged in the cabinet, a driving assembly is provided at the upper end of the cabinet, the driving assembly includes a driving device, the driving device is installed at the upper end of the cabinet, the driving shaft of the driving device is coaxially installed with a driving gear, the driving assembly also includes a rotating rod, the rotating rod passes through and is rotatably installed at the top of the cabinet, a rotating gear is coaxially installed at the upper end of the rotating rod, the rotating gear is meshed with the driving gear, the driving gear can drive the rotating gear to form intermittent rotation at a fixed angle, a cross rod is installed at the lower end of the rotating rod, and the conveying column is coaxially passed through and rotatably installed on the cross rod, so that the rotation of the cross rod can drive the conveying column to follow the rotation.

[0016] Preferably, a control system is installed in the cabinet, and the control system is used to control the opening and closing or operating speed of the drive device.

[0017] The beneficial effects of the present invention are: During use, the experimenter can immediately place a single cleaned test tube into the input component, and disinfect it in the high-temperature disinfection chamber through the intermittent rotation of the conveying structure. There is no need to wait until all the test tubes in the same batch are cleaned before placing them in the disinfection device for disinfection, so that instant processing is achieved as soon as they are cleaned, avoiding the drying and solidification of residues on the inner wall of the test tube, increasing the difficulty of disinfection, and improving the disinfection compliance rate. At the same time, the disinfected test tubes will enter the low-temperature storage chamber for storage. When the test tubes are needed, only the removal component needs to be driven to take out the single test tube for use, so that the test tubes no longer need to be transferred centrally after disinfection is completed, avoiding secondary contamination, thereby making the device significantly improve the disinfection effect and ensure the accuracy of the experimental data. At the same time, it can avoid secondary contamination of the test tubes and ensure that the test tubes are always kept clean and sterile before being taken out for use.

[0018] The opening and closing parts of the input component adopt an elastic shaft design. When the test tube is placed in, it automatically flips over to make way, and quickly rebounds and closes after the test tube is fully inserted. This can not only prevent external air from entering the high-temperature disinfection chamber, maintain a high temperature and clean environment in the chamber, but also prevent heat loss in the chamber, reduce energy loss, and prevent external impurities from contaminating the test tubes to be sterilized.

[0019] During the process of removing the test tubes, the blocking plate and the sealing plate of the removal assembly work together. The blocking plate covers the second drop trough, blocking the passage between the low-temperature storage chamber and the removal chamber to prevent the backflow of outside air when removing the tubes; the sealing plate simultaneously closes the chamber opening and cooperates with the sealing gasket to ensure the sealing of the removal chamber, maintain the sterile environment of the low-temperature storage chamber, and ensure that the remaining test tubes are not contaminated.

[0020] The detection device in the high-temperature disinfection chamber monitors the status of the test tubes in real time. When all test tubes are transferred to the low-temperature storage chamber, an instruction is automatically sent to shut down the high-temperature disinfection device. This function prevents the equipment from idling and accurately controls energy consumption. While ensuring the disinfection effect, it significantly reduces equipment operating costs and energy consumption.

[0021] By providing a protective layer, a shock-absorbing layer and an anti-wear layer, the risk of test tube damage is reduced in all directions. The protective layer prevents direct contact between the test tube and the conveying structure, preventing scratches on the bottom; the shock-absorbing layer placed in each ring groove cushions the impact of the test tube falling and moving, reducing the possibility of breakage; the anti-wear layer on the surface of the opening and closing parts replaces metal friction, avoiding wear on the outer wall of the test tube, and ensuring that the test tube remains intact throughout the entire process operation.

DETAILED DESCRIPTION

[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] like Figures 1 to 6 As shown, a high-temperature sterilization cabinet for laboratory test tubes of the present invention includes a cabinet body 10. The interior space of the cabinet body 10 is sequentially arranged from top to bottom as a high-temperature sterilization chamber 11, a low-temperature storage chamber 12, and a removal chamber 13. The high-temperature sterilization chamber 11 and the low-temperature storage chamber 12 are both provided with a conveying structure 14 of the same structure. A driving assembly 27 is provided at the upper end of the cabinet body 10. The driving assembly 27 can drive the conveying structure 14 to rotate intermittently at a fixed angle. An input assembly 15 and a plurality of high-temperature disinfection devices 21 are installed in the high-temperature disinfection chamber 11. The input assembly 15 is used to place the test tube in a vertical state into the high-temperature disinfection chamber 11, and the test tube is placed with its opening facing upward. A first placement ring groove 19 is provided on the bottom surface of the inner cavity of the high-temperature disinfection chamber 11. A first drop groove 16 is provided at the bottom of the first placement ring groove 19, and the first drop groove 16 and the input assembly 15 are staggered in the circumferential direction of the first placement ring groove 19. The conveying structure 14 includes a conveying column 141, which is rotatably installed in the high-temperature disinfection chamber 11, and the conveying column 141 is arranged on the driving assembly 27 for driving the conveying column 141 to rotate intermittently at a fixed angle. Several groups of positioning components are evenly arranged on the conveying column 141. 142, the positioning components 142 are evenly arranged along the circumferential direction of the conveying column 141. In the initial state, one group of positioning components 142 vertically corresponds to the lower end of the input component 15, and the adjacent group of positioning components 142 vertically corresponds to the first drop groove 16. When the driving component 27 drives the conveying column 141 to rotate intermittently at a fixed angle, each group of positioning components 142 can correspond vertically to the input component 15 or the first drop groove 16 in turn, so that the test tube placed by the input component 15 falls into the positioning component 142 and the bottom end of the test tube falls into the first placement ring groove 19. There is no need to wait until all the test tubes of the same batch are cleaned before performing the disinfection operation at the same time. The test tubes of the same batch can be placed one by one in the high-temperature disinfection chamber 11 according to the cleaning order. The positioning assembly 142 includes an upper positioning sleeve 1421 provided at the upper end of the conveying column and a lower positioning sleeve 1422 provided at the lower end of the conveying column. The upper positioning sleeve 1421 and the lower positioning sleeve 1422 are used to fix the test tube in a vertical position. The inner wall of the first drop groove 16 and the inner walls of the upper positioning sleeve 1421 and the lower positioning sleeve 1422 have the same diameter. When the test tube is placed, the inner walls of the upper positioning sleeve 1421 and the lower positioning sleeve 1422 are in contact with the outer circumference of the test tube. The upper positioning sleeve 1421 and the lower positioning sleeve 1422 are used to position the test tube so that the test tube can always be in a horizontal and vertical state in the first placement ring groove 19 for transportation under the drive of the conveying column 141. In the process of continuous transportation of the test tube by the conveying column 141, the high-temperature disinfection device 21 can perform high-temperature disinfection on the inner and outer surfaces of the test tube in all directions, and efficiently complete the disinfection operation. As the conveying column 141 continues to rotate, the first test tube placed on the upper positioning sleeve 1421 and the lower positioning sleeve 1422 will be vertically aligned with the first drop groove 16 provided on the first placement ring groove 19, and when the test tube is aligned with the first drop groove 16, it indicates that the test tube has completed the high-temperature disinfection operation; A plurality of sterile storage devices 23 are provided in the low-temperature preservation chamber 12, and a second placement ring groove 20 is provided on the bottom surface of the inner cavity of the low-temperature preservation chamber 12. The second placement ring groove 20 is coaxially arranged with the first placement ring groove 19, and a second drop groove 17 is provided at the bottom of the second placement ring groove 20. The second drop groove 17 is communicated with the removal chamber 13, and the second drop groove 17 is staggered with the first drop groove 16 and the input component 15 in the vertical direction. Since the conveying structure 14 in the low-temperature preservation chamber 12 has the same structure and principle as the conveying structure 14 in the high-temperature disinfection chamber 11, no further details will be given here. In the initial state, one group of positioning components 142 vertically corresponds to the first drop groove 16, and the adjacent group of positioning components 142 vertically corresponds to the second drop groove 17. When the conveying column 141 rotates intermittently at a fixed angle, each group of positioning components 142 can vertically correspond to the bottom of the first drop groove 16 or the top of the second drop groove 17 in turn.

[0034] When the test tubes placed on the upper positioning sleeve 1421 and the lower positioning sleeve 1422 are vertically aligned with the first drop groove 16, the test tubes will fall into the corresponding low-temperature storage chamber 12 through the first drop groove 16 under the action of gravity, and will be positioned and placed by the positioning component 142 in the low-temperature storage chamber 12, and the bottom of the test tube will fall into the second placement ring groove 20, so that it will be intermittently transported by the conveying column 141 in the low-temperature storage chamber 12, and the sterile storage device 23 will perform low-temperature sterilization operations on the test tubes in the low-temperature storage chamber 12, and the low-temperature storage chamber 12 will maintain a low-temperature and clean environment, effectively preventing The sterilized test tubes are prevented from being attached to pollutants such as microorganisms and dust in the air, thus avoiding secondary contamination and ensuring that the test tubes are always kept clean before being taken out for use, thereby completing the test tube disinfection operation steps and being able to complete the test tubes as they are cleaned and disinfected, thus avoiding problems such as reagent drying up and increased difficulty in disinfection caused by centralized collection, thereby improving the disinfection efficiency and effect. At the same time, the device can also automatically enter the low-temperature storage chamber 12 for storage after the test tubes have completed the disinfection operation, thus solving the risk of rupture caused by the test tubes continuing to be irradiated by the high-temperature disinfection device 21 after the test tubes have completed high-temperature disinfection, thereby improving safety. As the conveying column 141 continues to convey, the first test tube entering the low-temperature insulation chamber will correspond to the second drop groove 17 under the drive of the positioning component 142, so that the test tube will fall into the removal chamber 13 through the second drop groove 17 under the action of gravity, waiting for the experimenter to take it away. When there is already a test tube in the removal chamber 13, when other positioning components 142 in the low-temperature preservation chamber 12 correspond to the second drop groove 17, since there is a test tube in the removal chamber 13, the upper positioning sleeve 1421 and the lower positioning sleeve 1 The test tube fixed on 422 can no longer fall into the removal chamber 13. The test tube will rotate and be stored in the low-temperature storage chamber 12 along with the rotation of the conveying column 141. Only after the test tube in the removal chamber 13 is taken out can other test tubes enter the removal chamber 13 through the second drop chute 17. This ensures that the test tubes can be stored in the low-temperature storage chamber 12 after high-temperature sterilization and can be taken out as needed. This solves the problem of secondary contamination when the same batch of test tubes are transferred to the outside together after sterilization, and ensures that the test tubes are always kept clean and sterile before being taken out for use. The bottom surfaces of the first placement ring groove 19 and the second placement ring groove 20 are both provided with a shock-absorbing layer, so that when the test tube falls into the first placement ring groove 19 or the second placement ring groove 20, or moves in the first placement ring groove 19 or the second placement ring groove 20, it can protect the test tube and prevent the test tube from being broken due to falling or moving. The upper surface of the shock-absorbing layer is a smooth surface, which is more conducive to the movement of the test tube. A protective layer is provided on the upper surface of the conveying column 141 of the conveying structure 14 in the high-temperature disinfection chamber 11. The protective layer can prevent the test tube from contacting the upper surface of the conveying column 141 when the test tube does not correspond to the positioning component 142. The protective layer can ensure that the bottom of the test tube is not scratched.

[0035] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 As shown, a positioning shell 24 is provided in the removal bin 13. The positioning shell 24 is mounted on the inner top wall of the removal bin 13 and is aligned vertically with the second drop groove 17. The positioning shell 24 is U-shaped. A bay opening 25 is provided on the outer surface of the cabinet 10. The bay opening 25 communicates with the inner cavity of the removal bin 13. The bay opening 25 is larger than the length and diameter of the test tube, and the U-shaped opening of the positioning shell 24 faces the bay opening 25. The take-out assembly 18 is installed in the take-out bin 13. The take-out assembly 18 includes an electric push rod 181. The electric push rod 181 is installed at the bottom of the take-out bin 13. The telescopic end of the electric push rod 181 is installed with a connecting rod 182. One end of the connecting rod 182 is installed with a take-out tube 183. When the electric push rod 181 is in a retracted state, the take-out tube 183 is aligned with the positioning shell 24, and the take-out tube 183 has the same diameter as the inner wall of the second drop groove 17. The outer circumference of the connecting rod 182 is installed with a connecting column 184. The upper end of the connecting column 184 is installed with a The blocking plate 185, the upper surface of the blocking plate 185 is in close contact with the top surface of the removal bin 13. During the extension and recovery process of the electric push rod 181, the blocking plate 185 will pass through the top of the positioning shell 24 to cover the second drop groove 17. The outer circumference of the removal cylinder 183 is installed with a connecting rod 186, and one end of the connecting rod 186 is installed with a sealing plate 187. The sealing plate 187 can completely cover the bin opening 25, and a circle of sealing gasket is provided on the side of the sealing plate 187 to improve the sealing performance when the sealing plate 187 covers the bin opening 25; When the test tube in the taking-out bin 13 needs to be taken out, the electric push rod 181 is started, and the connecting rod 182, the connecting column 184, and the linkage rod 186 can simultaneously drive the taking-out tube 183, the blocking plate 185 and the sealing plate 187 to move in parallel, so that the test tube moves with the taking-out tube 183, and the blocking plate 185 will move toward the outside of the bin opening 25 and leak out of the bin opening 25. The sealing gasket will simultaneously separate from the cabinet 10 and release the sealing state. As the electric push rod 181 telescopically moves, the taking-out tube 183 is moved to the outside of the bin opening 25, and the experimenter can directly take out the test tube for use. During this taking-out process, the sealing plate 187 will follow and move, so that it will move from the top of the positioning shell 24 to the bottom of the second drop groove 17, and the blocking plate 185 will always cover the second drop groove 17 during the taking-out process, so that the test tube in the low-temperature storage bin 12 is now If the tube cannot enter the removal chamber 13 through the second drop chute 17, it will continue to be stored in the low-temperature storage chamber 12 under the drive of the conveying structure 14. At the same time, it can also block the air flow channel between the low-temperature storage chamber 12 and the removal chamber 13 to prevent the backflow of external air when taking out the tube, affecting the sterility of the low-temperature storage chamber 12. After the test tube is taken out, the electric push rod 181 can be started to retract, so that the removal cylinder 183 returns to the bottom of the positioning shell 24 to wait for a new test tube; the blocking plate 185 withdraws from the second drop chute 17 to restore the test tube falling channel; the sealing plate 187 covers the chamber opening 25 again, and the sealing gasket presses the cabinet 10 to restore the sealing of the removal chamber 13, thereby achieving the goal that the device can freely take out a single test tube for use, and there is no need to transfer the test tubes of the same batch to the outside at the same time, which can greatly reduce the secondary contamination of the test tube and ensure the accuracy of the experimental operation; A shock-absorbing layer is provided at the bottom of the inner cavity of the removal tube 183 , which can protect the test tube when it falls into the removal tube 183 and avoid the risk of the test tube being broken when it falls due to gravity.

[0036] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 9 As shown, the input component 15 includes a placement tube 151, which is installed on the top surface of the cabinet 10. The lower end of the placement tube 151 passes through the cabinet 10 and is located inside the high-temperature disinfection chamber 11, and the lower end opening of the placement tube 151 can vertically correspond to the positioning component 142 located in the high-temperature disinfection chamber 11. The inner wall diameter of the placement tube 151 is the same as the inner wall diameter of the upper positioning sleeve 1421. The upper end opening of the placement tube 151 is rotated by an elastic shaft to install an opening and closing piece 152 so that the opening and closing piece 152 can automatically rebound. A storage groove 153 is provided on the inner wall of the upper end of the placement tube 151, and the opening and closing piece 152 can be stored in the storage groove 153. When the test tube has been cleaned, the experimenter holds the test tube with the opening upwards and lightly presses the opening and closing piece 152 on the top of the test tube. The opening and closing piece 152 is flipped inward under pressure and embedded in the storage groove 153. Ensure that the opening and closing member 152 does not affect the smooth entry of the test tube into the placement tube 151, so that the test tube will fall vertically along the inner wall of the placement tube 151. When the upper positioning sleeve 1421 is vertically aligned with the placement tube 151, the test tube will fall by gravity so that the bottom of the test tube enters the first placement ring groove 19. The upper positioning sleeve 1421 and the lower positioning sleeve 1422 position it so that it can follow the upper positioning sleeve 1421 and the lower positioning sleeve 1422 to move in the first placement ring groove 19 to perform the disinfection operation. After the test tube is completely entered into the placement tube 151, the elastic shaft will drive the opening and closing member 152 to automatically reset and restore the closing device, thereby preventing external air from entering the high-temperature disinfection chamber 11 through the upper opening of the placement tube 151, and also preventing the heat inside the high-temperature disinfection chamber 11 from being dissipated to the outside through the placement tube 151. An anti-wear layer is provided on the upper surface of the opening and closing member 152. When the test tube is placed in, the sliding friction with the anti-wear layer replaces direct metal contact, which can prevent the outer wall of the test tube from being scratched or worn.

[0037] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 8As shown, the drive assembly 27 includes a drive device 271, which includes but is not limited to a motor. The drive device 271 is installed at the upper end of the cabinet 10. The drive shaft of the drive device 271 is coaxially mounted with a driving gear 272, and the driving gear 272 is not limited to a special-shaped gear and a cylindrical gear. The drive assembly 27 also includes a rotating rod 273, which passes through and is rotatably mounted on the top of the cabinet 10. A cross rod 275 is installed at the lower end of the rotating rod 273. The conveying columns 141 located in the high-temperature disinfection chamber 11 and the low-temperature storage chamber 12 are coaxially penetrated and rotatably mounted on the cross rod 275, so that the rotation of the cross rod 275 can simultaneously drive the conveying column 141 to rotate. The upper end of the rotating rod 273 is coaxially mounted with a rotating gear 27 4. The rotating gear 274 is meshed with the driving gear 272, so that the driving gear 272 can drive the rotating gear 274 to form a fixed-angle intermittent rotation, so that the positioning components 142 located in the high-temperature disinfection chamber 11 will have a group of vertically corresponding to the placement tube 151 under the fixed-angle intermittent drive of the conveying column 141 according to the installation sequence, and the positioning components 142 located in the low-temperature storage chamber 12 will have a group of vertically corresponding to the first drop groove 16 under the fixed-angle intermittent drive of the conveying column 141 according to the installation sequence, thereby achieving the ability to transport test tubes through intermittent rotation, so that the entire process of test tube input, disinfection, transfer to storage is automated and precisely controlled, solving the time lag and secondary contamination problems of the traditional centralized disinfection mode.

[0038] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 8 、 Figure 9 As shown, a control system 28 is installed inside the cabinet. When the test tube is placed in the placement tube 151, the sensor provided on the inner wall of the placement tube 151 will sense the entry of the test tube. After the test tube completely leaves the placement tube 151 and enters the positioning assembly 142, a control signal is generated to the control system 28. When the control system 28 receives the control signal, it sends an instruction to the drive device 271 to start the drive device 271, which drives the rotating gear 274 to rotate a certain angle through the active gear 272, causing the cross rod 275 to rotate an angle, so that the test tubes can be placed on the positioning assembly 142 and the first placement ring groove 19 in sequence, and undergo high-temperature disinfection operation in the high-temperature disinfection chamber 11 through the high-temperature disinfection device 21; After the system determines that the test tubes have been loaded, the control system 28 will issue an instruction to the drive device 271 to ensure that the high-temperature disinfection time of the last added test tube is not less than t. When the high-temperature disinfection time of the last added test tube is greater than t, the drive device 271 will autonomously rotate intermittently at a fixed angle and will no longer be activated according to the sensor. Thus, under the intermittent rotation at a fixed angle, the test tubes in the high-temperature disinfection chamber 11 are sequentially transported to the corresponding second drop trough 17, so that the test tubes can receive sufficient disinfection treatment before falling into the low-temperature storage chamber 12, completing the disinfection operation. The rotation speed of the conveying column 141 during this process is expressed by the following formula: Wherein, V represents the speed of each rotation of the driving round seat; t represents the minimum time required to complete the disinfection of the test tube; n represents the number of positioning components 142 provided on the conveying column 141; Note: The system determines that the test tube loading is complete in a manner including, but not limited to, the system automatically detecting that the high-temperature disinfection chamber 11 is full of test tubes, or manually inputting a signal indicating that the test tube loading is complete. The value range of t is greater than or equal to T, where T represents the shortest time for high-temperature disinfection. In the present invention, the value of T includes, but is not limited to, 20 minutes, 30 minutes, or 40 minutes.

[0039] like Figure 2-4 As shown, a detection device 22 is provided on the top wall of the high-temperature disinfection chamber 11. The detection device 22 is used to detect whether there are test tubes in the high-temperature disinfection chamber 11. When all the test tubes have entered the low-temperature storage chamber 12, the detection device 22 detects that there are no test tubes in the high-temperature disinfection chamber 11, or the system determines that the high-temperature disinfection chamber 11 is disinfected. It will issue an instruction to the control device to control the high-temperature disinfection device 21 to turn off, so as to achieve the goal of automatically turning off the high-temperature disinfection device 21 when there are no test tubes in the high-temperature disinfection chamber 11 and the high-temperature disinfection device 21 is no longer necessary for disinfection operations, thereby avoiding energy consumption.

[0040] like Figure 3 、 Figure 7 As shown, the surface of the cabinet 10 and the surface of the sealing plate 187 are provided with observation windows made of transparent material, so that the experimenter can better understand the transportation status of the test tubes inside the device, monitor the flow status of the test tubes in real time, and improve the operational safety and process controllability.

[0041] In summary, in the present invention, the angle of the fixed-angle intermittent motion controlled by the driving device is: R=360° / n; The time of intermittent motion detection is t1.
