Problems solved by technology

However, these filter elements generally exist: the use of a single single-layer filter element has only a single-layer water treatment effect, while the use of a composite filter element has different effects due to the different paths of the water filtered from the top and bottom of the filter element. question
Due to the existence of these problems, the safety and stability of the filtration effect when using domestic water and direct drinking water cannot be guaranteed.

Abstract

The present invention relates to a table-water purification technology field, especially a double-tube combined filter element, including an outer filtering layer, an inner tube, a lower cover of the inner tube, a special filtering material, an top cover of the outer filtering layer, a lower cover of the outer filtering layer and an insulation net. The advantage of the invention is that the double-tube combined filter element is small-sized, simple, convenient and practical. The double-tube combined filter element has same filtrating water stream paths, a simple structure and a low cost, and is capable of achieving a safe and stable water treatment effect.

Description

technical field [0001] The patent of the invention relates to the technical field of drinking water purification, in particular to a double-tube composite filter element. Background technique [0002] There are many types of currently known filter cores for drinking water. However, these filter elements generally exist: the use of a single single-layer filter element has only a single-layer water treatment effect, while the use of a composite filter element has different effects due to the different paths of the water filtered from the top and bottom of the filter element. question. Due to the existence of these problems, the safety and stability of the filtration effect when using domestic water and direct drinking water cannot be guaranteed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a small and practical double-tube composite filter element with simple structure, low cost and safe and stable filtering e...
