The other end of the gas inlet pipe 500 is used for connecting a pipeline for the circulation of the atomized gas so as to receive the atomized gas. The partition 400 is disposed to facilitate the air inlet pipe 500 to be disposed at a higher position relative to the air inlet pipe 200, so as to ensure that the liquid filtering medium in the liquid storage cavity 101 can maintain a higher liquid level.

Thus, the gas entering the liquid storage cavity 101 will float up to the liquid filtering medium and flow out of the filtering device 1 through the gas outlet hole 302 and the gas outlet channel 301 in sequence. Meanwhile, the arrangement of the air outlet 302 deviating from the air inlet pipe 300 can change the current situation that the air outlet 302 is easily wetted. It is understood that in other embodiments of the present application, the outlet pipe 300 may be provided with only one outlet hole.

This arrangement increases the distance between the outlet 300 and the liquid level of the filter medium, thereby reducing the amount of the filter medium that is splashed onto the outlet 300.

Further, along the predetermined direction Z, the air inlet hole 202 is disposed on a side of the air inlet pipe 200 away from the air outlet pipe 300. The gas flowing out of the inlet conduit 200 first flows downward as shown and then floats up out of the liquid filter media. The arrangement can prolong the flowing distance of gas in the liquid filtering medium, so that the gas is prevented from directly entering the liquid filtering medium from the gas inlet pipe 200 to a certain degree and escaping from the liquid filtering medium, and the phenomenon that the surface of the liquid filtering medium turns over and splashes wet the gas outlet pipe 300 is caused.

In order to facilitate the connection of the filtering apparatus 1 to an external device for outputting filtered gas, the filtering apparatus 1 further includes an exhaust pipe 600.

One end of exhaust pipe 600 is fixed to second wall portion 120 and communicates with exhaust passage 301; the other end of the exhaust pipe 600 extends downward as shown in the figure to prevent the whole intake pipe 500 from exceeding the height of the cabin body, so as to reduce the whole occupied space of the filtering device 1 to a certain extent, thereby facilitating the miniaturization of the filtering device 1. The other end of the gas outlet pipe 600 is used to connect a pipeline for the filtered gas to circulate, so as to output the filtered gas. It should be noted that, the present application does not limit the specific shapes of the air inlet pipe 500 and the air outlet pipe 600, and in other embodiments of the present application, the air inlet pipe 500 and the air outlet pipe 600 may also be tubular structures with other shapes, such as prisms, or the like, so as to achieve the mounting connection between the filtering device 1 and an external device.
