This creation is a gas cleaning device, which is mainly composed of one or more hexagonal columnar bodies. The hexagonal columnar body includes at least three functional layers, which are a gas suction layer, a gas cleaning layer, and a gas output layer in this order. The gas cleaning layer uses air plasma technology to purify the air, and the gas output layer of one hexagonal columnar body can be connected to the gas of another hexagonal columnar body by stacking a plurality of the aforementioned hexagonal columnar bodies. The suction layer is connected to enhance the cleaning ability of the gas cleaning device.本創作為一氣體潔淨裝置,該裝置主要為一或一個以上的六角柱狀本體組成,該六角柱狀本體包括至少三層功能層,其依序為氣體吸入層、氣體潔淨層、氣體輸出層,其中該氣體潔淨層利用電漿技術進行空氣淨化,並可藉由將多個前述的六角柱狀本體堆疊,將一六角柱狀本體的氣體輸出層連接另一六角柱狀本體的氣體吸入層的連結方式,以增強該氣體潔淨裝置的潔淨能力。
