Description
Technical Field
The invention relates to the technical field of water purifiers, in particular to a ceramic composite filter element and a water purifier.
Background
In order to solve the current situation of drinking water, the reverse osmosis water purifier is favored by users.
Reverse osmosis water purification machines typically wind a RO membrane (reverse osmosis membrane) wafer around a central tube, which is then mounted in a membrane housing. A plurality of water inlet holes are formed in the central pipe. The water filtered by the membrane enters the cavity of the central tube through the water inlet hole. Tap water can be filtered by a membrane to remove salts, heavy metals and the like, but cannot be used for smell removal, sterilization, pH value adjustment with weak acidity and the like. Therefore, after the membrane filtration, an active carbon filter element or other filter materials can be arranged at the rear part for absorbing organic matters, removing smell and bacteria, and the PH value is adjusted to be alkaline, so that the health of drinkers is facilitated. However, the overall structure of the rear filter element results in large volume of the overall structure, insufficient space utilization rate of the overall structure and high integration level.
To sum up, the composite filter element structure in the prior art has the problems of poor integration level, insufficient space utilization rate and insufficient functionality and needs to be solved.
