The air suction nozzles 503 are arranged on the lower side of the work surface 4. The output end of the air pump 501 is connected to the exhaust system 7. The exhaust system 7 includes a work surface exhaust piece 701 and an air curtain exhaust piece 702. The bottoms of the work surface exhaust piece 701 and the air curtain exhaust piece 702 are both connected to the exhaust nozzles 703. The work surface exhaust piece 701 corresponds to the work surface 4.

[0041] The present invention absorbs the air above the exhaust table 202 and the work table 4 through the air supply system 5, and then supplies air through the exhaust system 7, thereby forming an air curtain inside the clean air curtain 2. The clean air curtain technology ensures the biosafety of the environment when the sampled object takes off the mask. At the same time, under the action of the exhaust system 7 and the exhaust nozzle 503 on the other side of the isolation baffle 3, the clean positive pressure air supply technology is adopted to ensure the biosafety environment of the sampler. The unique control system technology constitutes a biological sampling safety device, which greatly improves the biosafety of the environment.

[0042] Further, such as Figure 2 and 7 As shown, a clean air curtain 2 is provided on the front side of the safety cabinet body 1, and the clean air curtain 2 includes an air supply table 201 and an exhaust table 202, and an air curtain exhaust member 702 is provided inside the air supply table 201, and the exhaust table 202 is connected to the air supply system 5, and an air curtain table filter 12 is fixedly provided on the exhaust table 202;

[0044] At the same time, a work surface filter 11 is arranged on the work surface 4, and a plurality of suction nozzles 503 are arranged below the work surface filter 11. The air pump 501 on the air supply system 5 absorbs the air inside the work surface 4 through the suction nozzles 503, and then discharges the air to the top of the work surface 4 through the exhaust system 7. The work surface filter 11 on the work surface 4 plays a supporting role as well as a filtering role, so that a circulating airflow can be formed, and negative pressure and high-efficiency exhaust technology is adopted to ensure the biosafety treatment of the exhaled gas of the sampled object.

After the air enters the filter box 8, the air is filtered by the activated carbon adsorption layer 901 and the cotton and linen layer 902 on the disinfection part 9, and then the moisture in the air is absorbed by the sponge layer 903, which greatly improves the purification rate of the air and ensures the biosafety environment of the sampler.

[0047] At the same time, a disinfection box door 804 is rotatably provided on the filter box 8, and a door handle 805 is provided on the outer side of the disinfection box door 804. The disinfection box door 804 is opened through the door handle 805 and the disinfection component 9 is replaced, which improves the convenience of use and subsequent repair and maintenance, thereby increasing the service life of the filter box 8.
