The liquid inlet 2 is connected to the middle position of the top of the shell 1 by welding. The liquid storage tank 3 is placed inside the shell 1. The liquid inlet 2 is located above the liquid storage tank 3. The bottom of the liquid storage tank 3 is connected to the pumping pump 4 by bolts. The pumping pump 4 is connected to the infusion tube 5. The infusion tube 5 passes through the liquid storage tank 3 and the shell 1, and the port is connected to the telescopic tube 6. The telescopic tube 6 is made of PVC and has the advantages of light weight, flexibility, corrosion resistance, and not easy to age. The port of the telescopic tube 6 is connected to the liquid outlet 7. The bottom of the shell 1 is connected to the placement table 8 by welding. The bottom of the placement table 8 It is connected with a plurality of anti-skid pads 15 distributed in a rectangular shape. The anti-skid pads 15 are made of rubber. Through the movement of the pumping pump 4, the liquid culture medium inside the liquid storage tank 3 is transported to the infusion tube 5 and the telescopic tube 6, and then flows out from the liquid outlet 7. It also includes a bidirectional screw 10, a knob 9, a clamping block 11 and a rubber pad 12. The upper part of the placement table 8 is rotatably connected with the bidirectional screw 10. The right end of the bidirectional screw 10 is connected to the knob 9 for assisting rotation by welding. The external thread of the bidirectional screw 10 is connected with symmetrically distributed clamping blocks 11. The sides of the two clamping blocks 11 that are close to each other are connected with rubber pads 12 for increasing friction. By rotating or reversing the bidirectional screw 10, the clamping block 11 is moved inward or outward.

[0025] See also Figure 1 and Figure 2 As shown, it also includes an electric slide rail 17 and an electric skateboard 18. The front side of the housing 1 is connected to the electric slide rails 17 distributed on the left and right by bolts. The electric skateboard 18 is slidably connected between the two electric slide rails 17. The electric skateboard 18 is fixedly connected to the liquid outlet 7, so that the liquid outlet 7 is driven to move when the electric skateboard 18 moves.

[0026] See also Figure 1 , Figure 2 and Figure 5 As shown, it also includes a rotating shaft 13 and a placement rack 14. The rotating shaft 13 is connected to the front side of the lower part of the shell 1 by welding.

[0028] First, the staff places the perfusion machine on the laboratory table, pours the liquid culture medium from the liquid inlet 2 into the liquid storage tank 3, and after the pouring is completed, the liquid inlet 2 is sealed with a blocking object, and then the electric slide rail 17 is turned on by the controller 16, and the electric slide plate 18 is controlled to move upward to the limit, thereby increasing the distance between the liquid outlet 7 and the placement table 8, and then the bottle is placed on the placement table 8, so that the bottle is placed between the two clamping blocks 11, and then the knob 9 is pinched by hand to rotate the bidirectional screw 10, so that the two clamping blocks 11 move inward synchronously to clamp the bottle, thereby improving the stability of the bottle and preventing the bottle from falling from the placement table 8. When clamping, the rubber pad 12 increases the friction between the clamping block 11 and the outer wall of the bottle to achieve a better clamping effect, and then the electric slide plate 18 is controlled to move downward When the bottle is filled with liquid culture medium, the pump 4 is turned on and the liquid culture medium in the liquid storage tank 3 is transported to the infusion tube 5 and the telescopic tube 6 in turn, and then flows out from the liquid outlet 7 into the bottle to realize the perfusion of the liquid culture medium. When the bottle is filled with liquid culture medium, the pump 4 is turned off and the electric slide 18 is controlled to move upward so that the liquid outlet 7 is disengaged from the bottle mouth of the bottle. The electric slide rail 17 is then closed and the bidirectional screw 10 is reversed so that the two clamping blocks 11 move outward synchronously and separate from the bottle. The bottle is removed from the placement table 8. When it is necessary to perfuse the liquid culture medium into the test tube, the placement rack 14 is rotated upward to 90 degrees and the test tube is placed in the placement rack 14. After placement, the above steps are repeated to perfuse the liquid culture medium into the test tube.
