The number of the jet ports 423 is not limited to three, and is determined according to the number of the spray nozzles. The specific type of the killing assembly is not limited to the spray nozzle, and may be an ultraviolet lamp, and when the killing assembly is an ultraviolet lamp, one side of the killing box 422 facing the sampling window is a hollowed-out design or is provided with a metal net, so that all the ultraviolet light emitted by the ultraviolet lamp is emitted to the area where the sampling window is located.

It will be appreciated that the drive member 430 is adapted to drive the kill box 422 in rotation about the axis of rotation 421 so that the area of kill defined by the spray nozzle is in the form of a fan.

It can be understood that, as shown in fig. 15 and 16, the killing assembly further comprises two electric fans 425, the electric fans 425 are arranged in the killing box 422, two air outlets 424 are formed on one side of the killing box 422 facing the sampling window, each air outlet 424 is located between two adjacent nozzles 423, and the positions of the air outlets 424 correspond to the positions of the electric fans 425 one by one. The electric fan 425 is used for blowing air to the sterilized area, so that the drying time of the disinfectant is shortened, and detection by later detection personnel is facilitated.

In order to increase the drying rate of the disinfecting liquid, an electric heating element (not shown) is further arranged in the disinfecting box 422, the electric heating element is an electric heating wire or an electric heating sheet, the electric heating element is located near the air outlet 424, the air blown by the electric fan 425 is heated by the electric heating element, the temperature of the air is rapidly increased, and the air drying speed of the disinfecting liquid can be further increased.

As can be understood from fig. 15 and 16, the driving member 430 further includes a motor mounting seat 432 and a speed reducer 433, the motor mounting seat 432 is used for providing a mounting base for the speed reducer 433 and the killing and driving motor 431, and a side of the motor mounting seat 432 facing the fixed base 410 is hollow, so as to provide a mounting space for mounting the driving pulley 434 and reduce a space occupied by the driving member 430. The motor mounting seat 432 is disposed on a side of the fixing base 410 away from the killing part 420, and the motor mounting seat 432 is connected with the fixing base 410 through a screw. The shell of the speed reducer 433 is connected with the motor mounting base 432 through a screw, the speed reducer 433 is coaxially arranged with the killing driving motor 431, the shell of the speed reducer 433 is connected with the shell of the killing driving motor 431 through a screw, and the input shaft of the speed reducer 433 is connected with the rotating shaft of the killing driving motor 431. The motor mounting base 432 is provided with a through hole, and an output shaft of the speed reducer 433 penetrates through the through hole and then is connected with the transmission assembly.

When the killing drive motor 431 rotates, the killing drive motor 431 drives the input shaft of the speed reducer 433 to rotate, the speed of the input shaft is reduced by the speed reducer 433, the output shaft of the speed reducer 433 drives the driving pulley 434 to rotate at a lower rotating speed, the driving pulley 434 which rotates at a low speed drives the driven pulley 435 to rotate through the synchronous belt 436, and the driven pulley 435 drives the rotating shaft 421 to rotate, so that the rotation of the killing box 422 is realized.

Here, the specific structure type of the transmission assembly is not limited to the combination of the pulley and the timing belt 436, but may be a gear set, for example, the output shaft of the speed reducer 433 is provided with a first gear, the second end of the rotating shaft 421 is provided with a second gear, and the first gear is engaged with the second gear. Of course, the number of gears in the gear train is not limited to two, and more gears may be provided as needed. Since the pipe and the wire are provided inside the rotating shaft 421, in order to prevent the pipe and the wire from being entangled, the maximum predetermined angle of the rotating shaft 421 should not exceed 360 °, and after rotating to the maximum predetermined angle, the rotating shaft reversely rotates to the initial position.

It can be understood that, as shown in fig. 15 and 16, the killing member 420 further includes a blocking plate 426, the blocking plate 426 includes a blocking plate main body and a connecting plate, the blocking plate main body is a rectangular plate, the connecting plate is a bent strip-shaped plate, and the blocking plate main body and the connecting plate are integrally formed.

It is understood that one end of the connection plate away from the main body of the blocking plate is connected to the end of the second end of the rotation shaft 421 by a screw. When the killing drive motor 431 drives the rotating shaft 421 to rotate, the blocking plate 426 and the killing box 422 synchronously rotate. When the sterilizing box 422 is rotated to the sampling window, the blocking plate 426 is also rotated to the sampling window and blocks the sampling window from the inner side of the housing, preventing the atomized disinfectant from entering the inside of the nucleic acid sampling apparatus.

It can be understood that, as shown in fig. 15 and 16, the driving member 430 further includes two adjusting brackets 437, the two adjusting brackets 437 are spaced apart from one side of the fixed base 410 facing away from the killing member 420, the two adjusting brackets 437 are located on one side of the motor mounting seat 432 facing the driven pulley 435, the adjusting brackets 437 are L-shaped brackets, and one end of the adjusting brackets 437 is connected with the fixed base 410 by screws.

The adjustment bolt 438 is adapted to adjust the distance between the motor mount 432 and the driven pulley 435. Since the timing belt 436 is used for a certain period of time, the timing belt 436 is loosened, which affects transmission efficiency. It is therefore necessary to adjust the position of the motor mount 432 so that the timing belt 436 remains tensioned. The specific adjustment mode is as follows: the screw in the through hole 439 is loosened, the adjusting bolt 438 is rotated by a tool, the motor mount 432 is pushed by the adjusting bolt 438 to move away from the driven pulley 435, and the screw in the through hole 439 is tightened by the tool after the timing belt 436 is in a tensioned state.

The working principle of the sampling window killing device is as follows:

when the nucleic acid sampling apparatus receives a signal indicating that the sampling is completed, the sterilizing drive motor 431 drives the rotation shaft 421 to rotate, thereby driving the sterilizing cassette 422 to rotate. Meanwhile, a signal is sent to the pressurizing pump assembly, the pressurizing pump assembly pumps disinfectant to the spray nozzle, so that the spray nozzle sprays atomized disinfectant to the area where the sampling window is located, the rotating killing box 422 drives the spray nozzle to rotate together, and rotary killing is achieved. After the set disinfection range is disinfected, the electric fan 425 is started to air-dry the disinfection area, and the specific air-drying time is set according to actual needs.
