Then, the pressing plate 113 and the limit rod 114 are reset to their original positions, and then the controller 104 is used to start the servo electric cylinder 105. At this time, the started servo electric cylinder 105 will, with the cooperation of the two single-headed bolts 107, the double-hole plate 108 and the connecting block 106, bring The dynamic pressure block 109 moves downward vertically. When the bottom of the pressure block 109 contacts the top of the pressure plate 113 and continues to move, the moving pressure block 109 will squeeze out the liquid in the biological sample with the cooperation of the pressure plate 113, four limit rods 114, the placement block 111, the placement table 110, the shell 102 and the base 101. At this time, the squeezed liquid will be absorbed by the two papers 112. At the same time, the shape of the specimen will be fixed and gradually become flat. When the biological sample is pressed to a suitable thickness, the controller 104 is used to pause the servo electric cylinder 105. At this time, the biological specimen will complete the drying and shaping operations under the combined action of pressure and dry environment.

[0024] The effect and working principle of the whole mechanism are as follows: when it is necessary to prepare biological specimens, first remove the two clamping rods 202 from the rectangular plate 201, then remove the rectangular plate 202 from the shell 102, then connect the controller 104 to the external power supply through the prepared power cord, then turn on the controller 104, set the valve opening degree of the electric regulating valve 204, the start time of the electric regulating valve 204 and the use procedure, then remove the porous plate 4, then manually open one of the manual valves 211, then inject a proper amount of clean water into the water storage shell 212 (to submerge the outlet end of the air outlet pipe 215 and the outlet end of the exhaust pipe 216), when the valve of one of the manual valves 211 is opened, the gas storage tank 20 3 will enter the interior of the electric regulating valve 204, and then the porous plate 4 will be reset and installed back to the initial position. When everything is ready, the pressing plate 113 is first removed from the other paper 112. At this time, the moving pressing plate 113 will drive the limit rod 114 connected to it to move, and then the other paper 112 is removed from one of the papers 112, and then the biological sample is placed on one of the papers 112, and then the other paper 112 is placed on the surface of the biological sample, and then the pressing plate 113 and the limit rod 114 are reset to their original positions, and then the rectangular plate 201 is reset, and the reset rectangular plate 201 is fixed by the cooperation of the two clamping rods 202 and the shell 102, and finally the clamping rod 202 is used to fix the reset rectangular plate 201. The controller 104 is used to start the servo electric cylinder 105. At this time, the started servo electric cylinder 105 will drive the pressing block 109 to move vertically downward with the cooperation of the two single-headed bolts 107, the double-hole plate 108 and the connecting block 106. When the bottom of the pressing block 109 contacts the top of the pressing plate 113 and continues to move, the moving pressing block 109 will squeeze out the liquid in the biological sample with the cooperation of the pressing plate 113, the four limit rods 114, the placement block 111, the placement table 110, the shell 102 and the base 101. At this time, the squeezed liquid will be absorbed by the two papers 112, and the shape of the specimen will be fixed and gradually become flat. When the biological sample is pressed to a suitable thickness, the controller 104 is used to pause the servo. The biological specimen is dried and shaped under the combined effect of pressure and dry environment. When the liquid squeezed out of the biological specimen contains viruses, the electric regulating valve 204 and the first electric valve 208 connected to one of the second round tubes 210 are opened by the controller 104. At this time, the chlorine dioxide gas entering the electric regulating valve 204 directly enters the L-shaped tube 205, then enters the corresponding three-way tube 207, then enters the opened first electric valve 208, then enters the second round tube 210, and then enters the space composed of one of the grooves of the housing 102 and the rectangular plate 202. When the chlorine dioxide gas enters the space,At this time, the gas will directly kill viruses in the space, biological specimens and components. When the closing time of the electric regulating valve 204 (depending on how long the electric regulating valve 204 is started) is reached, the controller 104 will close the electric regulating valve 204 and the corresponding first electric valve 208. When the space is completed with disinfection, the controller 104 will start the motor 206, open the first electric valve 208 connected to the other second circular tube 210 and the second electric valve 214 connected to the outlet pipe 215. At this time, the started fan 206 will filter the air in another groove of the shell 102 through the cooperation of the filter screen plate 6, and then suck it into the inside of the fan 206, and then transport it to the inside of the three-way pipe 207 connected to it, and then transport it to the inside of the three-way pipe 207. It is sent to the inside of the opened first electric valve 208, and then to the inside of the corresponding second circular tube 210, and then to the inside of the above-mentioned space. At this time, the gas (normal gas) transported to the inside of the space will bring the chlorine dioxide gas previously transported to the inside of the space into the inside of the air inlet pipe 213, and finally through the cooperation of the opened second electric valve 214 and the air outlet pipe 215, it is transported to the water storage shell 215 with water. When the mixed gas (normal gas and chlorine dioxide gas) is discharged into the water, the chlorine dioxide gas in the mixed gas will quickly dissolve into the water, and the normal gas will emerge from the water and then spread inside another groove of the shell 102. When the chlorine dioxide gas in the above-mentioned space is almost processed, Then, the controller 104 is used to close the corresponding second electric valve 214 and the corresponding first electric valve 208, and then the rectangular plate 201 is removed. Then, the controller 104 and the servo electric cylinder 105 are used to reset the pressing block 109 to the initial position, and then the sealing plate 218 is removed from the concave block 217. Then, the placement block 111, the two papers 112, the pressing plate 113 and the four limiting rods 114 are moved out of one of the grooves of the housing 102 together. Then, the pressing plate 113, the other paper 112, the biological specimen, one of the papers 112 and the placement block 111 are separated by wearing gloves, and are placed flat inside the concave block 217. Finally, the sealing plate 218 is installed back to the initial position. When the sealing plate 218 is installed, At this time, the controller 104 is used to open the electric regulating valve 204 and the first electric valve 208 connected to one of the first circular tubes 209. At this time, the chlorine dioxide gas entering the electric regulating valve 204 will be directly transported to the space composed of the concave block 217 and the sealing plate 218 through the cooperation of the L-shaped tube 205, the corresponding three-way tube 207, the opened first electric valve 208 and the corresponding first circular tube 209. At this time, the chlorine dioxide gas entering the space will directly disinfect the objects placed in the space. When the closing time of the electric regulating valve 204 (depending on how long the electric regulating valve 204 is started) is reached, the controller 104 will close the electric regulating valve 204 and the corresponding first electric valve 208.When the objects in the space are disinfected, the controller 104 is used to start the fan 206, open the first electric valve 208 connected to the other first circular tube 209 and the second electric valve 214 connected to the exhaust pipe 216. The started fan 206 will filter the air in the other groove of the shell 102 through the cooperation of the filter screen plate 6, and then suck it into the fan 206, and then transport it to the inside of the three-way pipe 207 connected to it, and then transport it to the inside of the opened first electric valve 208, and then transport it to the inside of the corresponding first circular tube 209, and then transport it to the inside of the space. At this time, the gas transported to the inside of the space (normal gas ) will bring the chlorine dioxide gas previously delivered to the interior of the space into the interior of the opened second electric valve 214, and then through the cooperation of the gas outlet pipe 215, it will be delivered to the water storage shell 215 with water. When the mixed gas (normal gas and chlorine dioxide gas) is discharged into the water, the chlorine dioxide gas in the mixed gas will quickly dissolve into the water, and the normal gas will emerge from the water and then spread inside another groove of the shell 102. When the chlorine dioxide gas inside the above space is almost processed, the controller 104 is directly used to close the corresponding second electric valve 214 and the corresponding first electric valve 208, and then the rectangular plate 201 can be removed.
