[0037] The ventilation mechanism 200 includes a telescopic conduit 210, one end of the telescopic conduit 210 is rotatably connected to the filter element assembly, and the other end of the telescopic conduit 210 is extruded and connected to the inner side of the ventilation fixing ring 220;

[0038] The supporting mechanism 300 includes a first supporting plate 310, a second supporting plate 320 and a third supporting plate 330. The first supporting plate 310 is fixedly connected to the bottom of the shell 110, and the third supporting plate 330 is fixedly connected to the outer side of the ventilation fixing ring 220. A plurality of moving wheels 350 are fixed to the bottom of the first supporting plate 310 and the second supporting plate 320. The first supporting plate 310 and the second supporting plate 320 can be moved by the moving wheels 350 for easy carrying.

[0039] Specifically, the ventilation main body mechanism 100 carried by the first supporting plate 310 is placed at the junction of the outdoors and the indoors, the filter element assembly and the shell 110 are rotated and clamped, and when the shell 110 is in operation, the indoor air is filtered by the air filter element 120 and flows to the outdoors. When fixed-point ventilation is required, the telescopic duct 210 and the air filter element 120 are rotated and clamped, and the second supporting plate 320 is moved to drive one end of the telescopic duct 210 to move to the position where ventilation is required. The telescopic duct 210 is stretched, and the air passes through the inside of the telescopic duct 210 and flows to the outdoors through the filter element assembly.

[0040] like Figure 2 and Figure 7As shown, in this embodiment, one end of the telescopic duct 210 is fixedly connected to multiple second clamping blocks 230, and the second clamping blocks 230 are used to rotate and clamp with the first clamping groove 130.

The inner wall of the ventilation fixing ring 220 is provided with multiple circular holes, which are fixedly connected to the extrusion spring 221, and the extrusion spring 221 is fixedly connected to the extrusion plate 222.

[0041] In specific implementation, the squeezing plate 222 is squeezed by the squeezing spring 221 so that the squeezing plate 222 squeezes and fixes the telescopic tube 210, which facilitates the removal and fixation of the telescopic tube 210 from the ventilation fixing ring 220 and also facilitates the adjustment of the position of one end of the telescopic tube 210.

[0042] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, in this embodiment, the adjacent sides of the first supporting plate 310 and the second supporting plate 320 are both serrated structures, a connecting block 311 is fixed to the bottom surface of the first supporting plate 310, the connecting block 311 is fixedly connected between the teeth of the first supporting plate 310, the second supporting plate 320 includes a fixing bolt 321, and through holes are provided on the top surface of the connecting block 311 and at the position of the second supporting plate 320 corresponding to the connecting block 311, and the fixing bolt 321 is movably inserted into the inner side of the through hole.

When the two are connected, the fixing bolt 321 is inserted into the through holes on the second carrier plate 320 and the connecting block 311, so that the first carrier plate 310 and the second carrier plate 320 are fixed. When they are separated, the first carrier plate 310 carries the shell 110, and the second carrier plate 320 drives the movement of the telescopic guide tube 210 to play different roles.

[0044] Embodiment 2

[0045] On the basis of the first embodiment, in order to make up for the problem that the telescopic catheter 210 in the first embodiment is inconvenient to store.

At this time, the relative positions of the second supporting plate 320 and the third supporting plate 330 are fixed and vertically swung. The ventilation fixing ring 220 fixedly connected to the third supporting plate 330 limits the telescopic guide tube 210, and the second supporting plate 320 can drive the end of the telescopic guide tube 210 to move synchronously when it moves. After use, the telescopic guide tube 210 is separated from the ventilation main body mechanism 100, and the third supporting plate 330 is pulled to drive the movable plug 341 to slide outward. At this time, the movable plug 341 squeezes the fixing spring 342, and then the third supporting plate 330 is rotated around the axis of the movable plug 341 to a position close to the horizontal and located above the second supporting plate 320. The telescopic guide tube 210 is stacked between the second supporting plate 320 and the third supporting plate 330 for storage, which is convenient for storage.

[0048] In the present invention, the output assembly includes a drive motor and fan blades installed at the output end of the drive motor. The drive motor is installed on the inner side of the housing 110.
