Description

Technical Field

[0001] The utility model belongs to the technical field of liquid tank filters, and particularly relates to a filter with a liquid tank sealing structure. Background Art

[0002] A liquid tank filter is a filter for air filtration commonly used in life, and most of it is installed at the end of the air outlet. Most of the liquid tank filters are of an integral replacement structure, and the finished filter is integrally installed during use. The use of the filter element inside the filter will gradually lose its filtering effect over time and according to the amount of dust carried at the end of the air outlet. The common sealing method of the liquid tank filter is to fill and seal with sealant, resulting in the inability to replace the filter element alone according to its consumption in later use. The disassembly of the filter element will cause the filled sealant to break, and it cannot provide a good sealing effect in later use. It is often necessary to disassemble and replace the liquid tank filter as a whole, which will increase the use cost of the user. The scrapped liquid tank filter can often only be recycled as waste, and there is waste in the use of this structure of liquid tank filter.

[0003] In summary, there are some problems in the use of the liquid tank filter sealed with sealant, so it is hoped to propose a new structure to solve the above technical problems. Summary of the Utility Model
