The upper part of the pipette 58 is limited on the upper side of the third circular plate 56.

[0052] Specific use of the present invention:

[0053] First, the staff rotates the first closed door 13 to open the operation chamber 19, takes out the six pipettes 58 on the third circular plate 56 to replace the gun tips, puts the six pipettes 58 with replaced gun tips back into the six placement holes 63 of the third circular plate 56, and marks the six pipettes 58 with numbers 1, 2, 3, 4, 5, and 6 respectively through the control system. The staff rotates the first closed door 13 to close the operation chamber 19. Next, the staff rotates the third closed door 21 to open the preparation chamber 18, puts the six test tubes 36 between the disc 23 and the first circular plate 24, and squeezes and limits the outer sides of the lower and upper parts of the test tubes 36 through the first rubber ring 26 and the second rubber ring 28, respectively, so that the lower end of the test tube 36 is located on the upper side of the annular elastic member 38. The control system marks the six test tubes 36 with numbers 1, 2, 3, 4, 5, and 6 respectively. The staff member turns the third closed door 21 to close the preparation chamber 18. Then the control system controls the first stepper motor 41 to start. The first stepper motor 41 starts to drive the first rotating shaft 40 to rotate. The first rotating shaft 40 rotates to drive the disc 23 and the first circular plate 24 to rotate, so that the six test tubes 36 are moved to the bottom of the saline tank 45 in sequence. The control system controls the first discharge pipe 46 to open, so that the saline in the saline tank 45 enters the six test tubes 36 in sequence, so that the six test tubes 36 are filled with 9 ml of saline. Among them, the No. 1 pipette 58 is located directly above one of the limit shells 51, and the No. 4 pipette 58 is located in the gap between the No. 1 test tube 36 and the No. 2 test tube 36.

[0054] Secondly, the staff rotates the second closed door 20 to open the sampling chamber 17, and puts the purified flat plate into the limiting shell 51. At this time, the control system controls the second feed pipe 59 to open, so that the liquid culture medium in the solution box 52 falls into the flat plate in the limiting shell 51 through the second feed pipe 59. The second feed pipe 59 is closed, and the control system controls the second stepper motor 50 to start. The second stepper motor 50 starts to drive the second circular plate 49 to rotate. The rotation of the second circular plate 49 drives the limiting shell 51 and the flat plate to move to the bottom of the No. 1 pipette 58. At this time, the fixed block 60 is located above the telescopic rod 61, and the control system controls the telescopic rod 61 to extend. The extension of the telescopic rod 61 pushes the fixed block 60 to move upward. The upward movement of the fixed block 60 lifts one side of the limiting shell 51 upward, so that the limiting shell 51 and the flat plate are tilted and placed on the upper part of the second circular plate 49.

[0055] Then, the control system controls the electric telescopic rod 53 to extend, and the electric telescopic rod 53 extends to drive the movable plate 57 and the second rotating shaft 55 to move downward, and the second rotating shaft 55 moves downward to drive the third circular plate 56 to move downward, and the third circular plate 56 moves downward to make the tip of the No. 1 pipette 58 contact the flat plate. Then, the third stepper motor 54 starts to drive the second rotating shaft 55 to rotate forward and reverse in a small range alternately, and the second rotating shaft 55 rotates to drive the third circular plate 56 and the tip of the No. 1 pipette 58 to move back and forth in a small range, and the tip of the No. 1 pipette 58 moves back and forth to scrape the blocky bacterial strains on the surface of the flat plate. The control system controls the No. 1 pipette 58 to repeatedly absorb the solution in the flat plate, and spray the solution into the flat plate again, so as to break up the clumped bacterial strains by the solution. The camera 62 is used to detect the breaking up of the bacterial strains on the surface of the flat plate.

[0056] After the clumped bacteria in the plate are broken up, the control system controls the No. 1 pipette 58 to start sucking 1 ml of the solution in the plate into the gun tip. The control system controls the electric telescopic rod 53 to contract and drive the third circular plate 56 to move upward, so that the gun tip of the No. 1 pipette 58 is moved out of the plate. Then, the third stepper motor 54 starts to drive the second rotating shaft 55 to rotate, the second rotating shaft 55 rotates to drive the third circular plate 56 to rotate, and the third circular plate 56 rotates to drive the gun tip of the No. 1 pipette 58 to move directly above the No. 1 test tube 36. The control system controls the No. 1 pipette 58 to spray 1 ml of the solution in the gun tip into the No. 1 test tube 36. At this time, the solution in the No. 1 test tube 36 is 10 ml of the shell.

[0057] Next, the control system controls the first stepper motor 41 to start, and the first stepper motor 41 starts to drive the first rotating shaft 40 to rotate, and the first rotating shaft 40 rotates to drive the disc 23 and the first circular plate 24 to rotate, and the disc 23 and the first circular plate 24 rotate to drive the No. 1 test tube 36 to revolve around the first rotating shaft 40, so as to preliminarily mix the bacterial suspension and the physiological saline in the No. 1 test tube 36. The disc 23 rotates to drive the sleeve 25 to revolve around the first rotating shaft 40, and the outer side of the second gear 44 is meshed with the outer side of the first gear 42, and the fixing ring 43 and the second gear 44 are fixed, so that the sleeve 25 and the No. 1 test tube 36 rotate, and the rotation and revolution of the No. 1 test tube 36 cooperate to improve the efficiency of mixing the bacterial suspension and the physiological saline, which is conducive to improving the efficiency of preparing the bacterial suspension. The rotation of the sleeve 25 drives the first annular plate 27 to slide in an annular manner in the upper part of the disc 23, and the rotation of the test tube 36 drives the second rubber ring 28 and the second annular plate 66 to rotate, so that the second annular plate 66 slides in an annular manner in the first circular plate 24, so as to make the test tube 36 rotate smoothly.

[0058] At the same time, the rotation of the disk 23 drives the fixed tube 29 and the push rod 30 to rotate, and the lower end of the push rod 30 moves from the first plane portion of the annular guide block 37 to the second plane portion of the annular guide block 37 through the inclined portion of the annular guide block 37, so that the push rod 30 moves upward under the guidance of the inclined portion of the annular guide block 37. The upper end of the push rod 30 slides in contact with the inclined surface of one end of the push rod 31, so that the push rod 30 moves upward to push the push rod 31 to move radially inward, and the push rod 31 moves to push the arc plate 34 and the arc rubber member 35. And under the action of the first rubber ring 26 and the second rubber ring 28, the arc rubber member 35 pushes the upper part of the No. 1 test tube 36 to move, so that the No. 1 test tube 36 is arranged obliquely in the first rubber ring 26 and the second rubber ring 28. Thus, during the movement of the lower end of the push rod 30 on the second plane portion of the annular guide block 37, the No. 1 test tube 36 is in an inclined arrangement state, and the rotation and revolution of the No. 1 test tube 36 cooperate, which is conducive to further improving the efficiency of uniform mixing of the bacterial suspension and the physiological saline. Among them, the movement of the push rod 31 drives the slider 32 to move, and the movement of the slider 32 squeezes the spring 33 to generate elastic force. A wave-shaped uneven structure is formed by a plurality of grooves 39 on one side of the second plane portion of the annular guide block 37, and under the elastic force of the spring 33, the push rod 31 moves back and forth, and the push rod 31 moves back and forth to drive the arc plate 34 and the arc rubber member 35 to move back and forth, and the arc rubber member 35 moves back and forth to swing the No. 1 test tube 36 back and forth, so that the bacterial suspension in the No. 1 test tube 36 is fully mixed with the physiological saline, which is conducive to improving the efficiency of bacterial suspension preparation.

[0059] When the solution in test tube No. 1 36 is mixed evenly, the disc 23 rotates to drive test tube No. 1 36 to move to the top of the turbidimeter 47 , and the turbidimeter 47 measures the light transmission or scattering of the solution in test tube No. 1 36 to estimate the number of bacteria, so as to quickly detect the concentration of the bacterial suspension in test tube No. 1 36 .

[0060] When the turbidimeter 47 detects that the concentration of the bacterial suspension in the No. 1 test tube 36 does not meet the requirements, the concentration of the bacterial suspension in the No. 1 test tube 36 is adjusted in time by adding physiological saline through the physiological saline tank 45 or by sucking the solution in the plate into the No. 1 test tube 36 through the No. 1 pipette 58.

[0061] When the turbidimeter 47 detects that the concentration of the bacterial suspension in the No. 1 test tube 36 meets the requirements, at this time, the No. 1 test tube 36 contains a 10% dilution of the shell bacterial suspension. The No. 1 test tube 36 moves to the bottom of the No. 2 pipette 58, and the control system controls the electric telescopic rod 53 to extend, and the electric telescopic rod 53 extends to drive the No. 2 pipette 58 to move downward, so that the tip of the No. 2 pipette 58 enters the No. 1 test tube 36, and the start of the No. 2 pipette 58 absorbs 1 ml of the solution in the No. 1 test tube 36 into the tip of the No. 2 pipette 58. The first stepper motor 41 starts to drive the disc 23 and the first circular plate 24 to rotate, so that the No. 2 test tube 36 moves to the bottom of the No. 2 pipette 58, and the control system controls the No. 2 pipette 58 to spray, and sprays the 1 ml dilution of the bacterial suspension in the tip of the No. 2 pipette 58 into the No. 2 test tube 36. The preparation component starts to shake the No. 2 test tube 36 vigorously, which is conducive to fully mixing the bacterial suspension in the No. 2 test tube 36 with the physiological saline. According to the above steps, the six test tubes 36 are diluted with bacterial suspension in turn, so that the contents of the No. 1, 2, 3, 4, 5, and 6 test tubes 36 correspond to the shell 10. -1 To housing 10 -6 dilution of bacterial suspension.

[0062] Finally, the working solution controls the control system through a plurality of control buttons 11, so that a bacterial suspension of a specific concentration can be quickly prepared as needed to improve the efficiency of microbial detection. The fan 65 is started to ventilate the interior of the housing 10, and the sterilizing ultraviolet light lamp 64 is started to sterilize and disinfect the interior of the housing 10.

Through the arrangement of the disc 23, the first circular plate 24, and the first rotating shaft 40, the first stepper motor 41 is started to drive the first rotating shaft 40 to rotate. The rotation of the first rotating shaft 40 drives the disc 23 and the first circular plate 24 to rotate. The rotation of the disc 23 and the first circular plate 24 drives the No. 1 test tube 36 to revolve around the first rotating shaft 40, so as to preliminarily mix the bacterial suspension in the No. 1 test tube 36 with the physiological saline. Then, through the arrangement of the sleeve 25, the first gear 42, and the second gear 44, the disc 23 rotates to drive the sleeve 25 to revolve around the first rotating shaft 40, and the outer side of the second gear 44 is meshed with the outer side of the first gear 42, and the fixing ring 43 and the second gear 44 are fixed, so that the sleeve 25 and the No. 1 test tube 36 rotate, and the rotation and revolution of the No. 1 test tube 36 cooperate to improve the efficiency of mixing the bacterial suspension and the physiological saline, which is conducive to improving the efficiency of bacterial suspension preparation.

Through the arrangement of a push rod 30, a push rod 31, an arc plate 34, an arc rubber member 35, a first rubber ring 26, and a second rubber ring 28, the rotation of the disk 23 drives the fixed tube 29 and the push rod 30 to rotate. The lower end of the push rod 30 moves from the first plane portion of the annular guide block 37 through the inclined portion of the annular guide block 37 to the second plane portion of the annular guide block 37, so that the push rod 30 moves upward under the guidance of the inclined portion of the annular guide block 37; the upper end of the push rod 30 slides in contact with the inclined surface of one end of the push rod 31, so that the push rod The push rod 30 moves upward to push the push rod 31 to move radially inward, and the push rod 31 moves to push the arc plate 34 and the arc rubber member 35; and under the action of the first rubber ring 26 and the second rubber ring 28, the arc rubber member 35 pushes the upper part of the No. 1 test tube 36 to move, so that the No. 1 test tube 36 is arranged obliquely in the first rubber ring 26 and the second rubber ring 28; therefore, during the movement of the lower end of the push rod 30 on the second plane portion of the annular guide block 37, the No. 1 test tube 36 is arranged obliquely, and the rotation and revolution of the No. 1 test tube 36 cooperate to further improve the efficiency of mixing the bacterial suspension and the physiological saline. The push rod 31 is moved by the setting of the slider 32, the spring 33 and the groove 39, and the slider 32 is squeezed by the movement of the slider 32 to generate elastic force; a wave-like uneven structure is formed by a plurality of grooves 39 on one side of the second plane portion of the annular guide block 37, and under the elastic force of the spring 33, the push rod 31 moves back and forth, and the push rod 31 moves back and forth to drive the arc plate 34 and the arc rubber member 35 to move back and forth, and the arc rubber member 35 moves back and forth to swing the No. 1 test tube 36 back and forth, so that the bacterial suspension in the No. 1 test tube 36 is fully mixed with the physiological saline, which is beneficial to improving the efficiency of bacterial suspension preparation.
