Once it reaches a suitable height, it is moved away from the vertical groove, causing it to drive the positioning block into the horizontal groove of the L-shaped slot. Finally, the second air outlet pipe is moved downwards, causing it to engage with the positioning block in the vertical groove at the lower end of the L-shaped slot, thus maintaining the stability of the second air outlet pipe. This design is simple, stable, and low-cost, with convenient adjustment. The upper end of the second air outlet pipe is threaded to the rear end of the connecting pipe, facilitating disassembly and cleaning of the connecting pipe. A PM sensor is installed on the filter plate. When the PM sensor indicates poor indoor air quality, the centrifugal fan is activated to ventilate the room. Attached Figure Description
