It is to be understood that the shape of the housing 10 is not limited thereto, but is preferably a rectangular parallelepiped.

Referring to fig. 2 and 3, the housing 10 is provided at least at a rear surface and each side surface thereof with at least one set of ventilation assemblies 40, and each ventilation assembly 40 includes an air inlet 401 and an air outlet 403. It should be noted that the casing 10 has an air inlet chamber 20 and an air outlet chamber 30, the air inlet chamber 20 is communicated with each air inlet 401, so that the outside air can enter the air inlet chamber 20 through the air inlet 401 for subsequent purification; the exhaust chamber 30 is connected to an exhaust opening 403, so that the exhaust gas obtained by purification can be discharged from the exhaust chamber 30 to the external environment through the exhaust opening 403. It can be understood that, in order to improve the exhaust efficiency, an exhaust fan 301 is provided in the exhaust chamber 30.

Each ventilation assembly 40 also includes an intake damper 402 and an exhaust damper 404. The air inlet baffles 402 correspond to the air inlets 401 one by one, the air inlet baffles 402 are detachably mounted on the shell 10, when the air inlet baffles 402 are mounted on the shell 10, the corresponding air inlets 401 are sealed, and when the air inlet baffles 402 are detached from the shell 10, the corresponding air inlets 401 are opened; the exhaust baffles 404 are in one-to-one correspondence with the exhaust ports 403, the exhaust baffles 404 are detachably mounted on the housing 10, when the exhaust baffles 404 are mounted on the housing 10, the corresponding exhaust ports 403 are closed, and when the exhaust baffles 404 are detached from the housing 10, the corresponding exhaust ports 403 are opened. It is understood that, for the convenience of the worker to disassemble and assemble, the air intake baffle 402 and the air exhaust baffle 404 are both preferably disposed on the surface of the casing 10; the air intake baffle 402 and the air exhaust baffle 404 are preferably mounted by screws or the like.

The new air blower further comprises an air inlet pipe 50 and an air outlet pipe 60, the air inlet pipe 50 and the air outlet pipe 60 are preferably provided with a group and detachably mounted on the shell 10, wherein the air inlet pipe 50 is communicated with any one of the air inlets 401, and the air outlet pipe 60 is communicated with any one of the air outlets 403.

For example, when the fresh air fan is backed on a wall, the air inlet baffle 402 and the air outlet baffle 404 on the back of the casing 10 are removed, the air inlet pipe 50 is installed on the back of the casing 10 and correspondingly communicated with the air inlet 401, the air outlet pipe 60 is installed on the back of the casing 10 and correspondingly communicated with the air outlet 403, and then the air inlet pipe 50 and the air outlet pipe 60 pass through the preset opening on the wall, so as to realize the air circulation between the outdoor and the fresh air fan.
