Composite filter element and water purification equipment with composite filter element

Abstract

The invention discloses a composite filter core and a water purifying device with the same. The composite filter core comprises a shell and a filter component; the shell is provided with a water inlet and a water outlet both positioned in the upper end of the shell; the filter component is arranged in the shell, separates the water inlet from the water outlet and comprises a carbon rod; the inner side of the carbon rod defines a first water passing passage; a second water passing passage is defined between the outer side of the carbon rod and the shell; one of the first water passing passage and the second water passing passage is communicated with the water inlet and the other is communicated with the water outlet. According to the composite filter core, the carbon rod is utilized to filter water to effectively remove harmful substances in the water, retain beneficial mineral matter in the water and improve the water quality and mouthfeel. In addition, the composite filter core can operate under the pressure of tap water without an external power source, thereby effectively reducing the drinking cost of a user and realizing environmental protection.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a composite filter element and water purification equipment with the composite filter element. Background technique [0002] In the face of various water pollution problems, the filter element of the water purifier in the related art is mainly made of PP (polyester) cotton, carbon particles and RO (reverse osmosis) membrane. PP cotton is mainly used to remove large sediment and rust substances in the water. , Granular carbon is mainly to absorb organic substances and residual chlorine in water, RO membrane is mainly to intercept ionic substances, organic substances and bacteria and viruses in water. These three types of filter elements need to be used together to intercept sediment, rust, and remove residual chlorine. Organic matter function, because of the small pore size of the RO membrane, the beneficial mineral elements in the water are usually removed, and the TDS...

[0002] In the face of various water pollution problems, the filter element of the water purifier in the related art is mainly made of PP (polyester) cotton, carbon particles and RO (reverse osmosis) membrane. PP cotton is mainly used to remove large sediment and rust substances in the water. , Granular carbon is mainly to absorb organic substances and residual chlorine in water, RO membrane is mainly to intercept ionic substances, organic substances and bacteria and viruses in water. These three types of filter elements need to be used together to intercept sediment, rust, and remove residual chlorine. Organic matter function, because of the small pore size of the RO membrane, the beneficial mineral elements in the water are usually removed, and the TDS (total dissolved solids) of the effluent water is extremely low, which is commonly referred to as pure water, which contains almost no Substances, not the most suitable water for drinking from a health point of view
