In the air supply process, when the indoor air needs to be subjected to external circulation, the first electric telescopic rod 28 far away from one side of the air inlet pipeline is controlled to extend for a preset length, the preset length can be set according to actual requirements, because the first electric telescopic rod 28 extends, the circulation opening of the elastic membrane 26 is reduced, and the elastic membrane 26 forms a similar cone shape, part of reverse wind from the air outlet nozzle to the air inlet pipeline appears on the edge of the inner wall of the round hole 14, the reverse wind blows the guide plate outwards, and the reverse wind drives the indoor air to enter the atmosphere from the sewage discharge pipe under the action of the reverse wind; thereby realizing the function of external circulation.
When the image recognition module detects that an object enters the air inlet pipeline, the first electric telescopic rod 28 close to one side of the air inlet pipeline is controlled to extend, so that the extrusion block 30 close to one side of the air inlet pipeline moves towards the axis of the fixing ring 27 and extrudes the elastic membrane 26, the air holes of the elastic membrane 26 are reduced to form bosses, the object entering the air inlet pipeline is blocked, and the object is discharged from the baffle plate opening under the action of the gravity of the object.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
