Embodiment Construction
[0010] The technical solutions and beneficial effects of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0011] like figure 1 As shown, the present invention provides an air purification device, comprising a housing 1, a fan 2, a filter layer 3 and at least two layers of adsorption layers 4, wherein the housing 1 is a closed device with an air inlet and an air outlet, so that An air duct is formed between the tuyere and the air outlet for air to pass through; the filter layer 3, the adsorption layer 4 and the fan 2 are sequentially arranged in the air duct of the housing 1, and are arranged in sequence from the air inlet to the air outlet; the adsorption layer 4 Activated carbon can be used, and two or more layers can be selected according to the surrounding environment conditions. In this embodiment, three layers are used as an example for illustration, wherein, each adjacent adsorption layer 4 is relatively interlaced...
