Composite filter element and water purification equipment

Abstract

The invention discloses a composite filter element and water purification equipment. The composite filter element comprises a shell, an isolation component, a first filter material and a second filtermaterial, wherein a filter cavity is arranged in the shell; the isolation component is arranged in the filter cavity and divides the filter cavity into a first filter cavity and a second filter cavity which are mutually independent; the first filter cavity is provided with a water inlet channel, a confluence channel and a water outlet channel which sequentially communicate with one another; the shell is provided with a first water inlet communicating with the water inlet channel and is provided with a first water outlet communicating with the water outlet channel; the shell is also provided with a second water inlet and a second water outlet which communicate with the second filter cavity; the first filter material is arranged in the water inlet channel and is positioned between the firstwater inlet and the confluence channel; and the second filter material is arranged in the second filter cavity and is positioned between the second water inlet and the second water outlet. Accordingto the technical scheme, the overall utilization rate of the first filter material in the composite filter element is improved, and the normal working life of the first filter material is ensured.

Description

technical field [0001] The invention relates to the field of water purification equipment, in particular to a composite filter element and water purification equipment. Background technique [0002] With the continuous improvement of people's living standards, people's requirements for water quality are getting higher and higher, so water purification equipment such as water purifiers have also attracted people's attention. Existing water purifiers are gradually developing towards miniaturization. The multi-stage filter element filtration system in the water purifier is often implemented with a composite filter element structure, thereby reducing the size of the filter element and improving the water purification effect. the goal of. [0003] In order to meet the user's filtration requirements for various water qualities, multiple independent filter chambers can be formed inside the composite filter element, so that the composite filter element has multiple independent filt...

Problems solved by technology

However, for this composite filter element, the filter material is located in the corresponding filter cavity, and the water flow is easy to pass through the position close to the water inlet and outlet of the filter cavity on the filter material, while the circulation effect of the water flow at other positions of the filter material is relatively poor. , which will lead to poor overall utilization of the filter material
