[0054] Embodiment 2
[0055] See attached Figure 7 As shown, an embodiment of the present invention further provides a working method of a portable floating bacteria collection device, comprising the following steps:
[0056] S1, horizontal adjustment of the base: the operator rotates the handle 390 to rotate the synchronous shaft 331 and rotate the first gear 335, which can drive the two first sprockets 332 on the surface to rotate, and at the same time, the second gear 350 and the third sprocket 360 are rotated through the transmission of the first gear 335, and the other synchronous shaft 331 is rotated through the transmission of the second chain 370. The rotation of the first chains 331 on both sides can drive the lifting seat 380 to move longitudinally, so as to adjust the level of the collection box 100;
[0057] S2, collection of floating bacteria: the culture dish 171 is placed on the tray 220, and the turbofan 260 is powered on by the collection switch 114. The negative pressure airflow generated by the turbofan 260 can connect the through hole 221 and the air inlet flange 230 to generate a negative pressure area, so that air is sucked in through the air inlet flange 230 and hits the culture dish 171 coated with agar culture medium, and the microorganisms in the air are "captured" on the agar culture medium;
[0058] S3, storage of planktonic bacteria: After completing step S2, the operator takes out the culture dish 171 from the tray 220, and places the culture dish 171 in the storage rack 170 of the storage chamber 112 for storage, and at the same time takes out another culture dish 171 from the storage rack 170 to carry out the next round of collection.
[0059] Specifically, the working principle of this portable floating bacteria collection device and method is as follows: when in use, the operator rotates the synchronous shaft 331 by turning the handle 390 and drives the first gear 335 to rotate. The first sprocket 332 on the surface of the synchronous shaft 331 drives the first sprocket 332 below the synchronous shaft 331 to rotate through the first chain 333. At the same time, the first gear 335 can drive the third sprocket 360 to rotate by meshing with the second gear 350. The second sprocket 336 drives the other synchronous shaft 331 to rotate through the transmission of the second chain 370, and the first sprocket 332 on its surface rotates. The first chain 333 drives the first sprocket 332 below the synchronous shaft 331 to rotate. At the same time, the first chains 333 on both sides drive the fixed plate 334 to move longitudinally along the guide rail 341, so that the lifting seat 380 drives the collection box 100 to move longitudinally. The height can be adjusted by adjusting the base 300 to ensure that the collection box 100 remains horizontal. When collecting, the culture dish 171 is placed on the tray 220, and the turbofan 260 is powered on by the collection switch 114. The negative pressure airflow generated by the turbofan 260 can connect the through hole 221 and the air inlet flange 230 to generate a negative pressure area, so that air is inhaled through the air inlet flange 230 and hits the culture dish 171 coated with agar culture medium, and the microorganisms in the air are "captured" on the agar culture medium; by using the battery pack 120, DC regulator, time relay 160, turbofan 260, and power display, the speed of the turbofan 260 can be effectively stabilized, and the battery pack 120 will no longer discharge after power failure, thereby achieving the stability of the turbofan 260, ensuring the accuracy of planktonic bacteria collection, and protecting the lithium battery pack 120.

2. A working method of a portable floating bacteria collection device, applied to the portable floating bacteria collection device according to claim 1, characterized in that: The following steps are involved: S1, horizontal adjustment of the base: the operator rotates the synchronous shaft (331) and rotates the first gear (335) by turning the handle (390), which can drive the two first sprockets (332) on the surface thereof to rotate. At the same time, the second gear (350) and the third sprocket (360) are rotated through the transmission of the first gear (335), and the other synchronous shaft (331) is rotated through the transmission of the second chain (370). The first chains (333) on both sides are rotated to drive the lifting seat (380) to move longitudinally, so that the collection box (100) can be adjusted horizontally; S2, collection of floating bacteria: placing a culture dish (171) on a tray (220), turning on the turbofan (260) through the collection switch (114), and energizing the turbofan (260). The negative pressure airflow generated by the turbofan (260) can connect the through hole (221) and the air inlet flange (230) to generate a negative pressure zone, so that air is sucked in through the air inlet flange (230) and hits the culture dish (171) coated with an agar culture medium, and the microorganisms in the air are "captured" on the agar culture medium; S3, storage of planktonic bacteria: After completing step S2, the operator takes out the culture dish (171) from the tray (220), and places the culture dish (171) in the storage rack (170) of the storage chamber (112) for storage, and at the same time takes out another culture dish (171) from the storage rack (170) to carry out the next round of collection.
