Central water purifier

Abstract

The invention provides a central water purifier. The central water purifier comprises a tank, a filter component, an air pump and a valve and is characterized in that the tank is of a hollow structure, the filter component is arranged inside the hollow tank, the valve is mounted at the top of the tank, a sealing cover is detachably mounted at the bottom of the tank, the valve is provided with a raw water inlet communicated with tap water, the valve is provided with a purified water outlet communicated with the internal space of the tank, and an ultrafiltration membrane is of a hollow structure. The water purifier has the advantages that the water purifier is reasonable in structural design, easy to demount, capable saving the time and physical power of staff during filter element replacingand convenient in fast filter element replacing; meanwhile, when a user is away from home for a long time, air can be fed into the tank through the air pump to discharge redundant water in the tank,bacterium breeding can be reduced, and economic cost increasing caused by frequency filter element replacing can be avoided.

Description

Technical field [0001] The present invention relates to the technical field of water purification equipment, in particular to a central water purifier. Background technique [0002] Central water purifier is a large-scale household water treatment equipment. It originated in 1832 and was invented by Barney Australia in the United Kingdom. It is suitable for central water purification in the whole house. Its core technology is mainly microfiltration (PP fiber cotton and activated carbon), ultrafiltration (Hollow fiber), KDF, ACF and ceramic filter elements. The central water purifier is installed in the main water inlet pipe to filter large particles such as sand and rust in the tap water. Imported KDF, coconut shell granular activated carbon and other core filter materials can absorb the chlorine and water impurities that are the most threatening to human health in tap water. Color, peculiar smell and other harmful substances, thereby improving the taste of purified water. [000...

AI Technical Summary

Problems solved by technology

[0003] At present, the central water purifier has covered every household, providing people with clean and healthy water sources. However, when the filter element inside the existing central water purifier needs to be replaced after being used for a long time, the central water purifier is Structural reasons make it difficult to replace the filter element, which is time-consuming and laborious; in addition, when the household user is away from home for a long time, the water in the central water purifier cannot be discharged in time, because the water is always in a static state and stays in the water purifier for a long time. Bacteria grow and attach to the surface of the filter element, bringing safety hazards to the user's drinking water again
