Description

TECHNICAL FIELD

[0001] The utility model relates to filter technical field, concretely is a filter. BACKGROUND

[0002] A filter is a device used to separate impurities from liquids or gases. It removes unwanted particles, pollutants or microorganisms through physical, chemical or biological methods, thereby achieving purification and treatment of fluids. Filters are widely used in many fields, including: water treatment: used to remove suspended solids, silt, bacteria, etc. in water to provide clean drinking water. Air purification: used in air conditioning, ventilation systems to remove dust, pollen, smoke and other pollutants in the air. Industrial applications: in chemical, food processing and other industries, filters are used to separate products and impurities to ensure product quality. Automobiles: used in automobile oil circuits and air intake systems to prevent impurities from damaging the engine. In modern water treatment systems, filters are one of the key components, bearing the important task of removing impurities and pollutants from water. However, most existing filters use threaded connections with water pipes. Although this connection method can ensure the firmness of the connection to some extent, it also has many shortcomings.

[0003] Firstly, threaded connections are easily affected by environmental factors, especially in humid or highly corrosive environments, the threaded part is prone to rust. This rust not only affects the sealing of the connection, but also may cause the connection between the filter and the water pipe to loosen, increasing the risk of water leakage. Secondly, the presence of rust makes it difficult to disassemble and replace the filter, especially in cases where regular maintenance and cleaning are required, threaded connections may require additional force, causing damage to the equipment or accidental accidents when disassembling. This inconvenience not only increases labor costs, but also may cause extended equipment downtime, affecting overall water treatment efficiency. Therefore, in view of the shortcomings of the existing filter and water pipe connection method, it is necessary to explore a more efficient, convenient and durable connection solution to improve the performance and maintenance convenience of the filter, to meet the needs of modern water treatment systems.

[0004] Therefore, we propose a filter. CONTENT OF THE UTILITY MODEL
