Meanwhile, the disinfectant has the characteristics of wide bactericidal spectrum, strong bactericidal capacity, high action speed, good stability, low toxicity, small corrosiveness, small irritation (mainly non-toxicity, no residue, no corrosion and no irritation), low price, easiness in obtaining, low environmental pollution degree and the like, so that the disinfectant is convenient to obtain and has a remarkable sterilization effect; in the scheme, the liquid inlet component 130 is filled with common disinfectant liquids of oxidation, aldehydes, phenols and alcohols.
Further, the air inlet 111 and the air outlet 114 are arranged in a vertically staggered manner, and the liquid inlet assembly 130 is installed below the high-position air port where the liquid inlet assembly 130 is located, so that the liquid inlet assembly 130 corresponds to the low-position air port, when disinfectant is poured into the U-shaped air passage, the liquid level of the disinfectant should not be lower than the low-position air port, and the liquid inlet assembly 130 is higher than the highest liquid level of the disinfectant, so that the disinfectant is prevented from being poured back into the liquid inlet assembly 130.

On the other hand, the second liquid level sensor 142 is closely arranged at the water outlet 113, and when the liquid level of the disinfecting liquid is lower than the second liquid level sensor 142, the second liquid level sensor 142 controls the second electromagnetic valve 150 to close.
The liquid inlet assembly 130 includes a pipe 131 and a first electromagnetic valve 132 for opening and closing the pipe 131, the pipe 131 extends into the U-shaped air passage from the outside of the transition pipe 112, the first electromagnetic valve 132 is electrically connected to the first liquid level sensor 141, and when the disinfectant liquid is sensed by the first liquid level sensor 141, the first liquid level sensor 141 controls the second electromagnetic valve 150 to open and also controls the first electromagnetic valve 132 to close so as to limit the disinfectant liquid in the pipe 131 from flowing into the U-shaped air passage.

In the first embodiment, referring to fig. 1, the filter assembly 120 is installed at one end near the air inlet 111, and the filter assembly 120 is connected to the inner wall of the U-shaped air passage and the isolation member 115, so that when the filter assembly 120 is replaced, the air exhaust device is detached from the exhaust system, so as to detach the filter assembly 120 from the air inlet 111.
In the second embodiment, referring to fig. 2, the filter assembly 120 is installed at one end near the air outlet 114, the filter assembly 120 is connected to the inner wall of the U-shaped air passage and the isolation component 115, and since the filter assembly 120 is near the air outlet 114, when the filter assembly 120 is replaced, the air exhausting device is detached from the air exhausting system, so as to detach the filter assembly 120 from the air outlet 114.
In the third embodiment, referring to fig. 3-7, the U-shaped air passage is formed by dividing through a partition 115, and the filter assembly 120 is installed on the side wall of the U-shaped air passage; and the filtering component 120 is abutted against the bottom of the isolation component 115, when the air flow passes through the U-shaped air passage, the air flow passes through the filtering component 120 twice, and secondary filtering is performed on the air flow through the single isolation component 115, so that the cleanliness of the discharged air flow is ensured.
However, since the isolation member 115 abuts against the isolation member 115, the area of the isolation member 115 is larger than the sectional areas of the air inlet 111 and the air outlet 114, so that the isolation member 115 is difficult to be detached from the air inlet 111 and the air outlet 114 at one end;
further, a fastening groove 1121 is formed at a position of the upper side wall of the transition pipe 112 corresponding to the position where the filter assembly 120 is disposed, so that the filter assembly 120 is inserted into the U-shaped air passage from the fastening groove 1121 of the upper side wall of the transition pipe 112, thereby facilitating the assembly and disassembly of the isolation component 115.
