[0021] See also Figure 1-4 The utility model provides a technical solution: a floating bacteria adopting device, comprising an upper cylinder 1 and a lower cylinder 2. In this embodiment, an ultraviolet germicidal lamp 5 is installed on the inner side wall of the upper cylinder 1. By setting the ultraviolet germicidal lamp 5, the interior of the upper cylinder 1 is disinfected and sterilized. Compared with the traditional disinfection method, the ultraviolet germicidal lamp 5 can be used to perform sterilization without corroding the components to be sterilized. The upper cylinder 1 is sequentially installed with a first filter plate 11 and a second filter plate 6 from top to bottom. The first filter plate 11 is provided to filter the floating particles in the air to prevent contamination of the culture dish 63. The second filter plate 6 is provided to perform secondary filtration. The vacuum pump 4 is protected to prevent debris from entering and damaging the vacuum pump 4. A support block 61 is fixedly connected to the top surface of the second filter plate 6. A mounting seat 62 is fixedly connected to the top surface of the support block 61. The support block 61 is installed to increase the filter hole area of ​​the second filter plate 6, thereby increasing the air flow rate and improving the sampling efficiency of planktonic bacteria. A positioning groove is provided on the top of the mounting seat 62. The culture dish 63 is inserted into the positioning groove of the mounting seat 62 to limit the culture dish 63 and prevent it from tipping over. The first filter plate 11 is located on the upper part of the culture dish 63 and does not contact the culture dish 63, thereby increasing the contact area between the culture dish 63 and the air and improving the sampling efficiency of planktonic bacteria.

[0022] In this embodiment, a fixing block 12 is installed on the outer wall of the upper cylinder 1, a hinge 13 is installed on the side wall of the fixing block 12, and a cylinder cover 3 is installed on the end of the hinge 13 away from the fixing block 12 to prevent dust from falling into the upper cylinder 1 and causing pollution during storage, and the cylinder cover 3 is prevented from being lost through the hinge 13.

[0023] In this embodiment, an air pump 4 is provided inside the lower cylinder 2, and the bottom of the air pump 4 is installed at the bottom of the lower cylinder 2.

The external thread of the mounting ring 14 and the internal thread of the mounting groove 22 are threadedly connected, which is convenient for the staff to disassemble during maintenance and cleaning.

[0028] During specific use: place the culture dish 63 in the positioning groove of the mounting seat 62, limit the culture dish 63 to prevent it from tipping over, turn on the vacuum pump 4 to start working, and speed up the circulation of air in the upper cylinder 1 by setting the vacuum pump 4 to increase the sampling rate of planktonic bacteria. The first filter plate 11 set in the upper cylinder 1 is used to filter debris in the air to prevent contamination of the culture dish 63. The first filter plate 11 is located on the upper part of the culture dish 63 and does not contact the culture dish 63, thereby increasing the contact area between the culture dish 63 and the air and improving the sampling efficiency of planktonic bacteria. The planktonic bacteria in the air are collected through the culture dish 63, and a secondary filtration is performed through the second filter plate 6 to prevent debris from entering the vacuum pump 4 and causing damage.

[0029] When disinfection is required before use, turn on the ultraviolet sterilization lamp 5 to disinfect the culture dish 63, the first filter plate 11, the second filter plate 6 and the inner wall of the upper cylinder 1. By setting the ultraviolet sterilization lamp 5, the interior of the upper cylinder 1 is disinfected and sterilized. Compared with the traditional disinfection method with disinfectant, the use of the ultraviolet sterilization lamp 5 can perform sterilization operations without corroding the components to be sterilized. When the sampling is completed and needs to be stored, cover the cylinder cover 3 to prevent dust from falling into the upper cylinder 1 and contaminating the culture dish 63 during storage. The cylinder cover 3 is connected by a hinge 13 to prevent it from being lost.

[0030] After long-term use, when the interior of the device needs to be cleaned or maintained, a mounting ring 14 is set at the bottom of the upper cylinder 1, and a mounting groove 22 is opened on the inner wall of the upper part of the lower cylinder 2. The internal thread of the mounting ring 14 is adapted to the internal thread of the mounting groove 22.
