In order to improve the strength of the bellows body 100 after installation, two reinforcing ribs 130 are arranged on the side wall of the bellows body 100 connected with the nucleic acid sampling cabin 400, the side wall of the bellows body 100 is provided with a through hole 110, and the through hole 110 is a weak position of the side wall of the bellows body 100, so that the two reinforcing ribs 130 are respectively arranged on the upper side and the lower side of the through hole 110, and the bellows body 100 is installed on the inner wall of the nucleic acid sampling cabin 400 by utilizing the reinforcing ribs 130, so that the stability of the mounted bellows body 100 is improved.

Optionally, the two reinforcing ribs 130 are located on the inner side wall of the wind box body 100 where the through hole 110 is provided. Therefore, in order to reduce the gap between the wind box body 100 and the inner wall of the nucleic acid sampling cabin 400, the two reinforcing ribs 130 are arranged on the inner side wall of the wind box body 100 provided with the through hole 110, after the side wall of the wind box body 100 is connected with the inner wall of the nucleic acid sampling cabin 400 through the two reinforcing ribs 130, the gap between the side wall of the wind box body 100 and the inner wall of the nucleic acid sampling cabin 400 is smaller, and the stability of the wind box body 100 is higher.

Specifically, the reinforcing rib 130 and the side wall of the bellows body 100 are provided with through holes 131 for mounting screws. The bellows body 100 is fixed on the inner wall of the nucleic acid sampling chamber 400 through a screw passing through the reinforcing rib 130 and a through hole 131 in the side wall of the bellows body 100.

Specifically, each reinforcing rib 130 is provided with three through holes 131 which are uniformly distributed, the two reinforcing ribs 130 are provided with six through holes 131, the side wall of the bellows body 100 is provided with six through holes 131 at positions corresponding to the two reinforcing ribs 130, and when the bellows body 100 is installed, the two reinforcing ribs 130 and the bellows body 100 are fixed on the inner wall of the nucleic acid sampling cabin 400 through six screws.

Thus, when the bellows body 100 is installed on the inner wall of the nucleic acid sampling cabin 400, the high-efficiency filter 320 and the surrounding frame 310 can be synchronously preassembled to form the filter package 300, the high-efficiency filter 320 and the fan 210 can be synchronously preassembled, after the bellows body 100 is installed and fixed, the fan package 200 and the filter package 300 are sequentially installed inside the bellows body 100 and in the installation opening 120, the assembly efficiency is further improved, when the high-efficiency filter 320 needs to be disassembled and replaced, only the high-efficiency filter 320 in the surrounding frame 310 needs to be disassembled, the replacement efficiency of the high-efficiency filter 320 is improved, the installation opening 120 is plugged through the surrounding frame 310, the high-efficiency filter 320 plugs the flow passing space 311 inside the surrounding frame 310, the air tightness between the installation opening 120 and the filter package 300 can be improved, and the aerosol in the external environment is further reduced from entering the nucleic acid sampling cabin 400.

Optionally, the mouth rim of the air intake side of the enclosure 310 has a flap 312 turned towards the inside. Like this, when installing high efficiency filter 320 in enclosing frame 310 inboard space 311 that overflows, high efficiency filter 320's air inlet end can be blockked by turn-ups 312, reinforcing high efficiency filter 320's installation stability, and the setting of turn-ups 312 can also improve the gas tightness between enclosing frame 310 inside wall and high efficiency filter 320, reduces the risk that outside dirty air is revealed from enclosing the gap between frame 310 inside wall and high efficiency filter 320.

Optionally, the corner of the enclosure 310 is provided with a removable clamp 313 to confine the high efficiency filter 320 within the plenum 311 by the clamp 313. In this way, the high efficiency filter 320 attached to the inside of the enclosure frame 310 can be pressed and fixed by the pressing plate 313, and the high efficiency filter 320 is prevented from shaking and falling off.

Specifically, each corner of the frame 310 is provided with a detachable pressing plate 313 for pressing and fixing the corner of the high efficiency filter 320. In this way, the mounting stability of the high efficiency filter 320 is further improved.

It can be understood that the pressing plate 313 and the surrounding frame 310 are detachably connected through a screw structure, and when the high-efficiency filter 320 needs to be replaced, the pressing plate 313 at the corner of the surrounding frame 310 is only needed to be detached one by one, so that the high-efficiency filter 320 can be detached from the surrounding frame 310.

Alternatively, the pressure plate 313 may be one of oblong, triangular, and rectangular. Specifically, the pressing plate 313 is in a strip shape, and two ends of the pressing plate 313 are respectively erected on two side walls of the corner portion of the enclosure frame 310.

Optionally, the lateral side of the installation opening 120 corresponds to the lateral wall of the bellows body 100 and has a screw hole, and the surrounding frame 310 is installed in the installation opening 120 by screws to block the installation opening 120.

Specifically, after the surrounding frame 310 is installed, glue is applied to the periphery of the surrounding frame 310 to seal the gap between the surrounding frame 310 and the installation opening 120. Further enhancing the air tightness between the surrounding frame 310 and the mounting opening 120 and reducing the risk of leakage of the outside dirty air from the gap between the surrounding frame 310 and the mounting opening 120.

Referring to fig. 9 and 10, in some embodiments, the blower mounting structure for a nucleic acid sampling compartment further comprises: the louver 500. The louver 500 is provided on the side wall of the wind box 100 where the mounting opening 120 is provided, and can guide the airflow blown out from the mounting opening 120. Thus, the air flow passing through the high efficiency filter 320 is guided by the louver 500, so that the intake air flow is more uniformly diffused into the nucleic acid sampling chamber 400, and the louver 500 can also play a dustproof role, thereby reducing the risk of pollution on the air outlet side of the high efficiency filter 320 in the mounting opening 120.

Specifically, the outer side of the louver 500 has a flange 510 bent toward the bellows body 100. Thus, since the bellows body 100 is horizontally installed, when the louver 500 is covered on the side wall of the bellows body 100 where the installation opening 120 is provided, the outer wall of the bellows body 100 in the horizontal direction can be engaged by the folded edge 510 of the outer side of the louver 500, thereby playing a role of hanging, and improving the stability of the louver 500.

In one embodiment, as shown in fig. 10, the shutters 500 are detachably connected to the side wall of the wind box 100 by using a magnetic attraction structure 520. In this way, the magnetic connection structure 520 is used to connect the louver 500 to the bellows body 100, so that when aerosol concentration scanning is required on the air outlet side of the high efficiency filter 320, the louver 500 can be conveniently detached, and the installation of the louver 500 after scanning is convenient.

Optionally, the magnetically attractive connection structure 520 includes: a magnetic attraction bar 521 and a magnetic metal bar 522. One of the magnetic attraction strips 521 and 522 is disposed on the sidewall of the wind box 100, and the other side is disposed on the sidewall of the louver 500 facing the wind box 100, so that the magnetic attraction strips 521 can be attracted to the magnetic metal strips 522 to fix the louver 500 when the louver 500 is covered on the sidewall of the wind box 100. Thus, under the adsorption restriction of the magnetic adsorption strips 521 and the magnetic metal strips 522, the covering stability of the louver 500 is ensured, and the louver 500 is convenient to disassemble and assemble.

Specifically, the magnetic attraction strips 521 are disposed on the side wall of the wind box 100, and the magnetic metal strips 522 are disposed on the side wall of the louver 500 facing the wind box 100.
