specific Embodiment approach 1
[0012] Specific implementation mode one: combine Figure 1 to Figure 3 Explain that an indoor and outdoor air filter exchange device in this embodiment includes a face mask 1, a time control switch 2, a power switch connecting rod 3, a power switch 4, a filter layer 7, a rotary valve 13, an axial flow fan 20, and an inner sleeve 21 and the outer sleeve 22, the outer sleeve 22 is vertically inserted on the body of wall 6, the outer sleeve 22 includes the outer sleeve outer tube 22-1 and the outer sleeve inner tube 22-2, the outer sleeve outer tube 22-1 and the outer sleeve inner tube 22- A cavity is formed between the 2, and an outer sleeve flange 22-3 is provided on the front end surface of the outer sleeve outer tube 22-1, and the outer sleeve flange 22-3 is fixed to the inner surface of the wall body 6 by a plurality of set screws 17. Connected, the inside of the outer sleeve 22 is set with an inner sleeve 21, the front end of the inner sleeve 21 is provided with an inner sl...
specific Embodiment approach 2
[0016] Specific implementation mode two: combination Figure 1 to Figure 3 Note that the rotary baffles of the rotary valve 13 in this embodiment are arranged alternately with the multiple casing air inlets 16 on the casing outer tube 22 - 1 . Other compositions and connection methods are the same as those in Embodiment 1.
[0017] In such a design, the rotary valve 13 is set on the outer casing 22, and the rotating baffle of the rotary valve 13 intersects with the casing of the outer casing outer tube 22-1 of the outer casing 22 to control the switch of the tuyere and adjust the size of the tuyere.
specific Embodiment approach 3
[0018] Specific implementation mode three: combination Figure 1 to Figure 3 Illumination, the indoor and outdoor air filtration and exchange device described in this embodiment also includes an electric heater 18 and a negative oxygen ion generator 19, and the electric heater 18 and the negative oxygen ion generator 19 are arranged in the inner casing sequentially from front to back 21 and is located at the front end of the axial flow fan 20, the heating control signal output end of the controller 12 is connected to the switch control signal input end of the electric heater 18, and the generation control signal output end of the controller 12 is connected to the negative oxygen ion generator 19 The switch control signal input terminal. Other compositions and connection modes are the same as those in Embodiment 1 or 2.
[0019] The electric heater 18 designed in this way can realize the heating of the air entering the room, improve the overall temperature of the room, and is ...
