[0033] like Figures 1 to 2 As shown, a fixing plate 208 is fixedly connected to one side of the fixing racks 207, and the fixing plate 208 is fixedly assembled above the cell liquid delivery platform 1. The fixing plate 208 assembles and fixes the fixing racks 207 and the assembly rack 301.

[0034] like Figures 1 to 2 As shown, a connecting pipe 209 is inserted below the positive pressure input pipe 201 and the negative pressure output pipe 202. The connecting pipe 209 connects the positive pressure input pipe 201, the negative pressure output pipe 202 and the cell fluid delivery pipeline.

[0035] like Figures 1 to 2 As shown, one side of the connecting pipe 209 is engaged with a support bracket 210, and the support bracket 210 is fixedly assembled above the cell liquid transport platform 1. The connecting pipe 209 is assembled and limited by the support bracket 210.

[0036] like Figures 3 to 6 As shown, a positive pressure piston block 203 is slidably mounted in the positive pressure input tube 201. By controlling the downward movement of the positive pressure piston block 203, the cell fluid contained in the positive pressure input tube 201 is positively pressured and discharged.

[0037] like Figures 3 to 6 As shown, a positive pressure driving rod 204 is fixedly connected to the top of the positive pressure piston block 203. The positive pressure driving rod 204 plays the role of assembly limit and movement control for the positive pressure piston block 203.

[0038] like Figures 3 to 6 As shown, a negative pressure piston block 205 is slidably mounted in the negative pressure output tube 202. By controlling the rise of the negative pressure piston block 205, the cell fluid is extracted under negative pressure.

[0039] like Figures 3 to 6 As shown, a negative pressure driving rod 206 is fixedly connected to the upper part of the negative pressure piston block 205. The negative pressure driving rod 206 plays the role of assembly limit and movement control for the negative pressure piston block 205.

[0040] like Figures 1 to 2 As shown, the positive pressure driving rod 204 and the negative pressure driving rod 206 are fixedly connected to the driving top plate 211 at their ends away from the cell solution delivery platform 1. By controlling the movement of the driving top plate 211, the positive pressure driving rod 204 and the negative pressure driving rod 206 are driven and controlled, thereby facilitating the control of the compression delivery state of the positive pressure input tube 201 and the negative pressure output tube 202.

[0041] like Figures 1 to 2 As shown, a connector 212 is fixedly connected between the driving top plate 211 and the threaded slider 303. The connector 212 serves to connect the threaded slider 303 and the driving top plate 211, so that the driving top plate 211 can drive the positive pressure driving rod 204 and the negative pressure driving rod 206 to move and control as the threaded slider 303 moves.

[0042] like Figures 3 and 4 As shown, the outer sides of the positive-pressure piston block 203 and the negative-pressure piston block 205 are each fitted with a sealing ring 213. The provision of the sealing ring 213 ensures a sliding seal between the positive-pressure drive rod 204 and the negative-pressure drive rod 206. A plurality of evenly distributed vent holes are provided on each of the positive-pressure drive rod 204 and the negative-pressure drive rod 206.

[0043] like Figures 3 and 4 As shown, a plurality of positive pressure sealing pads 214 are hingedly connected to the bottom of the positive pressure piston block 203. The vent holes on the positive pressure piston block 203 are controlled to be unidirectionally conducted by the plurality of positive pressure sealing pads 214.

[0044] like Figures 3 and 4 As shown, a plurality of negative pressure sealing pads 215 are hinged on the top of the negative pressure piston block 205, and a plurality of positive pressure sealing pads 214 and the negative pressure sealing pads 215 are all arranged in conjunction with the vent holes. The negative pressure sealing pads 215 play a one-way conduction role on the negative pressure piston block 205.

[0045] like Figures 5 and 6 As shown, the drive control assembly 3 is assembled between the positive pressure input pipe 201 and the negative pressure output pipe 202. The drive control assembly 3 includes an assembly frame 301, which is fixedly assembled between the positive pressure input pipe 201 and the negative pressure output pipe 202. The assembly frame 301 is used to assemble and limit the movable screw 302 and the drive motor 308.

[0046] like Figure 1 As shown, both sides of the assembly frame 301 are fixedly connected to the limiting side plates 304, and a pair of threaded sliders 303 are slidably matched with the limiting side plates 304. The limiting side plates 304 play a role of sliding guide for the pair of threaded sliders 303.

[0047] like Figure 1 As shown, a top plate 305 is fixedly mounted on one side of a pair of limiting side plates 304, and the assembly frame 301, a pair of limiting side plates 304 and the top plate 305 cooperate to form a transmission control box. The top plate 305 is used to seal and protect the moving screw 302 and the synchronous gear 307.

[0048] like Figures 5 and 6As shown, an inner partition 306 is fixedly connected to the assembly frame 301. A pair of movable screws 302 are rotatably connected to the inner partition 306. The inner partition 306 and the assembly frame 301 form a gear transmission cavity. The inner partition 306 is used to limit the assembly position of the movable screws 302 and also to separate and limit the threaded slider 303 and the synchronous gear 307.

[0049] like Figures 5 and 6 As shown, a pair of movable lead screws 302 are rotatably connected in the assembly frame 301. The movable lead screws 302 play the role of assembly limit and movement control for the threaded slider 303.

[0050] like Figures 5 and 6 As shown, the outer sides of a pair of movable screws 302 are both threadedly connected with threaded sliders 303, and the pair of threaded sliders 303 are respectively connected to the positive pressure driving rod 204 and the negative pressure driving rod 206. By controlling the lifting and lowering movement of the threaded sliders 303, the positive pressure piston block 203 and the negative pressure piston block 205 are raised and lowered.

[0051] like Figures 5 and 6 As shown, one end of a pair of movable lead screws 302 located in the gear transmission cavity is fixedly connected to a synchronous gear 307, and the pair of synchronous gears 307 are meshed with each other. Through the mutual meshing of the pair of synchronous gears 307, the pair of movable lead screws 302 can rotate synchronously under the action of the synchronous gears 307.

[0052] like Figures 5 and 6 As shown, a drive motor 308 is fixedly mounted below the assembly frame 301, and the output shaft of the drive motor 308 is in driving connection with a single movable lead screw 302. The drive motor 308 provides power, and by controlling the operation of the drive motor 308, the movable lead screw 302 is rotationally driven, thereby facilitating control of the movement state of the threaded slider 303.

[0053] Specifically, the driving motor 308 is commercially available and can be purchased and used directly.

[0054] During specific use, the cell fluid can be collected and stored through the positive pressure input tube 201 and the negative pressure output tube 202. Subsequently, the positive pressure input tube 201 and the negative pressure output tube 202 are assembled on one side of the fixed plate 208 through the fixing frame 207, and the positive pressure input tube 201 and the negative pressure output tube 202 are connected to the cell fluid delivery pipeline by connecting the connecting tube 209.

[0055] When it is necessary to control the input and output states of the cell fluid, the movable screw 302 can be driven to rotate by controlling the operation of the drive motor 308. The pair of movable screws 302 rotate synchronously under the cooperation of the synchronous gear 307. The threaded slider 303 moves up and down with the rotation of the movable screw 302 under the action of the internal and external threads. The positive pressure piston block 203 is driven to descend by the threaded slider 303 to positively pressure the cell fluid in the positive pressure input pipe 201. Since the pair of movable screws 302 rotate synchronously under the meshing action of a pair of synchronous gears 307, the pair of movable screws 302 are in a reverse rotation state during actual operation. When the positive pressure piston block 203 descends, the negative pressure piston block 205 will rise under the action of the internal and external threads. The negative pressure output pipe 202 is in a negative pressure state due to the rising of the negative pressure piston block 205, thereby playing the role of negative pressure extraction of the cell fluid.

[0056] Furthermore, during the descent of the positive-pressure piston block 203, the vent holes on the outside of the positive-pressure piston block 203 can be sealed and limited by a plurality of positive-pressure sealing pads 214. When the positive-pressure piston block 203 ascends, the plurality of positive-pressure sealing pads 214 open under the action of gas pressure, thereby opening the vent holes and allowing outside air to be replenished into the positive-pressure input pipe 201 through the vent holes. Similarly, during the descent of the negative-pressure piston block 205, the plurality of negative-pressure sealing pads 215 close the vent holes, thereby allowing negative pressure to be drawn into the negative-pressure output pipe 202 by the ascending negative-pressure piston block 205. When the negative-pressure piston block 205 descends, the negative-pressure sealing pads 215 open the vent holes under the action of gas pressure, allowing air in the negative-pressure output pipe 202 to be discharged through the vent holes.

[0057] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
