Technical Field

[0001] This utility model relates to the field of filter technology, specifically to a sterile composite filter. Background Technology

[0002] The filter cartridge is made of durable composite materials, possessing excellent chemical stability and mechanical strength, making it adaptable to various water quality environments. Its design balances filtration efficiency and service life, meeting the routine water purification needs of both household and industrial settings. The filter cartridge surface undergoes special treatment to effectively reduce impurity adhesion and lower maintenance frequency. Its compact structure facilitates easy installation and makes it suitable for a variety of water purification devices.

[0003] The sterilization effect of this filter cartridge has obvious shortcomings. Some microorganisms cannot be completely inactivated. After long-term use, bacteria may grow on the surface of the filter material, posing a risk of secondary pollution. Frequent replacement is required to maintain the basic purification effect.

[0020] The specific implementation process of this utility model is as follows: In use, by inserting the connector 32 into the plug 31, the connector 32 drives the positioning frame 36 to insert into the mounting frame 2. Then, the limiting sleeve 34 is rotated, so that the limiting sleeve 34 and the connector 32 undergo threaded movement, thereby limiting the connector 32 and keeping the connector 32 stable when it is inserted into the plug 31, thus keeping the ultraviolet lamp 3 stable during use. The system includes a coarse filter layer 11 to intercept large particles such as rust, silt, and suspended particles in the water, protecting the structure of subsequent layers. A pre-adsorption layer 12 primarily adsorbs residual chlorine, odor substances, and some organic pollutants, reducing water irritation.
