[0026] like Figure 2 and Figure 3 As shown, the inner walls on both sides of the purification box 10 are fixedly connected to limit blocks 18, and an activated carbon filter plate 17 is slidably connected between the outer surfaces of the two limit blocks 18. When external air enters the purification box 10, the air will be adsorbed and purified by the internal activated carbon filter plate 17. The micropores and pores on the surface of the activated carbon filter plate 17 will adsorb various harmful gases and particulate matter, such as sulfur dioxide, nitrogen oxides, volatile organic compounds, etc., thereby purifying the air.
