Disclosed is an air filtration device, which is used together with a combustion device. The air filtration device comprises a first tank body (1), a second tank body (2) and a liquid communicating pipe unit (51), wherein a combustion-supporting liquid (4) is accommodated inside the first tank body (1). The air filtration device also comprises an air inlet hole (122) via which the inner space of the first tank body (1) is in communication with the outside, and an air duct (13) which is in communication with the air inlet hole (122) in the first tank body (1), wherein the air duct (13) extends into the combustion-supporting liquid (4) and has an end hole (131) which is located in the combustion-supporting liquid (4); and air inside the second tank body (2) is in communication with air inside the first tank body (1). The air filtration device also comprises an air exhaust hole (222) via which the combustion device is in communication with an inner space of the second tank body (2), and a filter element (23) which is installed in the inner space of the second tank body (2), wherein the first tank body (1) is in communication with the second tank body (2) via the liquid communicating pipe unit (51). The air filtration device has a simple structure, and can add a combustion-supporting component in the air, so as to improve the combustion efficiency of combustion devices, such as an engine, etc. |
