The electronic dust collection module has a built-in high-voltage electric field and high-energy ion field, and charged particles generated in the high-voltage electric field and high-energy ion field or charged particles in the air are deposited on the anode of the high-energy ion field.

A further technical solution is: the gas composite filter module is a detachable integrated structure, which is composed of a plurality of gas composite filter plates and corresponding fixing brackets. When replacing, only the gas composite filter plate needs to be replaced. Multiple gas composite filter plates are connected end-to-end in an inverted "V" shape between the fixed brackets to increase the gas contact area.

A further technical solution is: a fixing and sealing component is arranged between adjacent gas composite filter plates, so as to facilitate the installation of multiple gas composite filter plates.

A further technical solution is: the gas composite filter plate is a cuboid one-piece structure, and is fixed with an aluminum alloy material frame around it; the gas composite filter plate is divided into seven layers and distributed symmetrically, the outermost two layers are symmetrically distributed with filter films, and the second The outer two layers are symmetrically distributed aluminum alloy material mesh, and then the inner two layers are symmetrically distributed with special adsorption material fiber felt for flue gas, and the middle layer is high-efficiency activated carbon fiber felt.

The further technical solution is: the fiber mat layer of the special adsorption material attached to the flue gas is a microscopic material that has a strong selective adsorption effect on harmful substances such as tobacco-specific nitrosamines and benzo[a]pyrene in the flue gas components. It is made of mesoporous materials and porphyrin compounds attached to fiber mats. The micro-mesoporous material is made of one or a combination of micro-mesoporous carbon composite material, metal pillared montmorillonite coated mesoporous silicon composite material, micro-mesoporous core-shell composite molecular sieve or MCM-48 mesoporous molecular sieve , the porphyrins are prepared by mixing cobalt porphyrin or protoporphyrin derivatives or a combination thereof.

Compared with the prior art, the present invention has the following beneficial effects: the present invention collects the smoke generated during smoking in time through the smoke collection cover, and sends it into the air inlet through the ventilation pipe; To balance the air and improve the uniformity of the air intake, so that the air passes through the pre-filter module evenly, and the large particles in the air are filtered first, which prevents the large particles in the air from directly entering the electronic dust collection module and affecting the electronic dust collection module. Purification efficiency and service life. The gas shroud and pre-filter module can be easily taken out for cleaning or replacement.

The pre-filtered air containing cigarette smoke enters the electronic dust collection module. After the particulate matter and charged particles in the cigarette smoke are captured by the electronic dust collection module, the gas enters the gas composite filter module. Small molecular organic matter and fine dust are adsorbed or filtered out to achieve the purpose of purifying indoor air.

The invention collects cigarette smoke in time through the smoke collection cover, and effectively utilizes multiple purification technologies such as "pre-filtration + electronic dust collection to capture particulate matter and charged particles + selective adsorption + activated carbon adsorption + high-efficiency particle filtration", forming a multi-stage The filter and purification device can purify indoor air, especially suitable for the purification of cigarette smoke. It has the advantages of large flow rate, high efficiency, good durability, and low maintenance cost.
