Problems solved by technology

[0003] In daily life, people often use air purifiers, fresh air fans and other products to purify the air, but both air purifiers and fresh air fans have only one aspect of efficacy. Air purifiers can purify indoor air but cannot purify the fresh and pleasant outdoor air. It should be introduced into the room, and the fresh air should not be introduced into the room when the outdoor temperature is extremely low or extremely hot. Otherwise, it will not only consume the energy of the indoor air conditioner, but also cause a huge change in the indoor temperature, making it impossible for people to adapt. If the fresh air and air purification The combination of the two devices can be used according to the location and time. The filter device is a necessary part of the air purifier and the fresh air fan to prevent external dust and impurities from entering the room. Dust and impurities, because the filter device is a consumable, after a period of use, the filter device needs to be replaced. The replacement of the filter device on the existing air purifier and fresh fan is complicated, and special personnel are required to replace it
