[0002] At present, as people's health awareness gradually improves, people have higher and higher requirements for indoor working and living environments. Air conditioners, as electrical appliances that can adjust room temperature and provide people with a more comfortable indoor environment, are also constantly innovating and improving. Adding a structure with a fresh air function to the air conditioner can inhale fresh air from the outdoors into the room, which can increase the oxygen concentration in indoor places and improve the cleanliness of the indoor air environment. However, the existing fresh air component filter component is inconvenient to disassemble and clean, and the filtering effect may be poor. For example, a Chinese patent discloses "a fresh air component and a fresh air air conditioner", and its application number is: "202022716740.9". During its use, fresh air flows out from the air outlet of the shell and enters the room, thereby improving the indoor air environment; a heat exchange component is arranged at the air outlet to control the temperature of the fresh air about to enter the room, so that the temperature of the fresh air is closer to the temperature of the indoor air, so that the indoor temperature will not change much after the fresh air enters the room and mixes with the indoor air. While improving the indoor air quality, the influence of the fresh air component on the indoor temperature is reduced, but the purification and filtering component of the component is single, and after one cycle, the filtering effect may be poor.
