[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with illustrations and specific embodiments.

[0030] like Figures 1 to 4 As shown, a gas impurity filtering device proposed by the utility model includes a base 1, which is used to provide an installation space; it also includes a filter cartridge 2, which is arranged on the base 1, and a filter chamber 3 is opened inside the filter cartridge 2, an opening 4 is arranged on one end of the filter cartridge 2, and the opening 4 is connected to the filter chamber 3, and an air inlet 5 and an air outlet 6 are also arranged on the filter cartridge 2, and the air inlet 5 and the air outlet 6 are connected to the filter chamber 3; a sealing unit, which is arranged on the opening 4 of the filter cartridge 2, and the sealing unit is used to improve the filter cartridge 2; a filter unit, which is arranged in the filter chamber 3, and the filter unit is used to filter impurities contained in the gas.

[0031] In this embodiment, the sealing unit includes a sealing cover plate 7, which is arranged on the opening 4 and is used to seal the opening 4; a sealing gasket 8, one end of which is bonded to the lower surface of the sealing cover plate 7, and the sealing gasket 8 is used to improve the sealing between the sealing cover plate 7 and the opening 4, effectively preventing external impurities from entering the filter chamber 3 during the filtration process, thereby ensuring the filtration effect.

[0032] In this embodiment, the filter unit includes a first mounting portion 9, the outer side of the first mounting portion 9 is connected to the inner wall of the filter cartridge 2, a first mounting groove is provided on the first mounting portion 9, a first filter element 10 is provided in the first mounting groove, and the first filter element 10 is used to preliminarily filter the gas passing through the first mounting portion 9;

[0033] The second mounting part 11, the outer side of the second mounting part 11 is connected to the inner wall of the filter cartridge 2, the second mounting part 11 is provided with a second mounting slot, the second mounting slot is provided with a second filter element 12, the second filter element 12 is used to perform secondary filtration on the gas passing through the second mounting part 11, after the preliminary filtration of the first filter element 10, the second filter element 12 mainly processes the remaining tiny particles and harmful substances. The second filter element 12 can further remove trace harmful substances in the gas and improve the purity of the gas.

[0034] Preferably, the first filter element 10 and the second filter element 12 are both made of activated carbon. The first filter element 10 and the second filter element 12 made of activated carbon can effectively remove impurities and harmful substances in the gas and improve the purity of the gas.

[0035] In this embodiment, a connecting portion 13 is provided on the side of the sealing cover plate 7, a connecting groove is opened on the filter cartridge 2, and the end of the sealing cover plate 7 is arranged on the filter cartridge 2 through the connecting portion 13 and the connecting groove. This design further enhances the connection stability and sealing between the sealing unit and the filter cartridge 2.

[0036] In this embodiment, an observation portion 14 is provided on the filter cartridge 2, and an observation window 15 is provided in the observation portion 14. The observation window 15 is a component made of transparent material. The situation in the filter cavity 3 can be observed through the observation window 15, which is convenient for immediate replacement of the filter element.

[0037] In this embodiment, the air inlet 5 is connected to an external air source (not shown in the figure), and the air outlet 6 is connected to an external fan (not shown in the figure). When in use, the gas to be filtered is passed into the filter cartridge 2 through the air inlet 5. At the same time, the fan is started to form a negative pressure, so that the gas passes through the first filter element 10 and the second filter element 12 in turn for filtering treatment.

[0038] The use process and principle of the utility model are as follows: when in use, connect the external air source to the air inlet 5, connect the external fan to the air outlet 6, and check whether each connection is tight and sealed; turn on the power of the external fan, the fan starts to run, and a negative pressure environment is formed. At this time, the gas enters the filter cartridge 2 from the external air source through the air inlet 5. The gas entering the filter cartridge 2 first passes through the first filter element 10 for preliminary filtration to remove larger particles and impurities. Then, the gas passes through the second filter element 12 for secondary filtration to further remove tiny particles and harmful substances. After two layers of filtration, the pure gas is discharged from the air outlet 6 and enters the external fan for subsequent treatment or discharge. During the filtration process, the user can observe the situation in the filter chamber 3 through the observation window 15, including the degree of contamination of the filter element, the flow state of the gas, etc. When it is found that the filter element is seriously contaminated, the external air source and the fan should be turned off in time, the sealing cover plate 7 should be opened, and the filter element should be taken out for replacement or cleaning. After long-term use or completion of the filtering task, the external gas source and fan should be turned off, all connections should be disconnected, and the filter cartridge 2 and the filter element should be thoroughly cleaned and maintained to ensure that a good filtering effect can be maintained the next time it is used. Through the above steps, the gas impurity filtering device can effectively remove impurities and harmful substances in the gas and improve the purity of the gas.
