Self-cleaning interior-exterior two-stage robot cleaning equipment of water purifier

Abstract

The invention discloses self-cleaning interior-exterior two-stage robot cleaning equipment of a water purifier. The equipment is mainly composed of two stages of filter elements; a barrel-type ceramic filter element is adopted as the first-stage filter element and composed of a ceramic inner core and a first outer barrel, tap water flows into the barrel-type ceramic filter element from a water inlet formed in one end of the ceramic inner core, and yielding water comprises the tap water and initial filtered water; a barrel-type ultrafiltration membrane filter element is adopted as the second-stage filter element and composed of an ultrafiltration membrane inner core and a second outer barrel, the initial filtered water flows into the barrel-type ultrafiltration membrane filter element from a water inlet formed in one end of the second outer barrel, and yielding water comprises the initial filtered water and fine filtered water. The equipment has the advantages that the ceramic inner core is cleaned (first-stage cleaning) by the tap water when the tap water flows through the ceramic inner core, the ultrafiltration membrane inner core is cleaned (second-stage cleaning) by the initial filtered water when the initial filtered water flows through the second outer barrel, first-stage cleaning and second-stage cleaning are both performed at the normal water pressure of the tap water without needing to use a booster pump, and therefore not only are energy saving and consumption reducing achieved, but also the structure of the equipment is simplified; meanwhile, the failure rate is greatly decreased, and therefore the input cost and maintenance cost of the equipment are reduced.

Description

Technical field [0001] The invention relates to a cleaning equipment for a water purifier, in particular to a robot self-cleaning internal and external double-stage cleaning equipment for a water purifier, belonging to the technical field of water purifiers. Background technique [0002] At present, most water purifiers use pp cotton or ultrafiltration membrane as the cleaning filter element, while pp cotton and ultrafiltration membrane are used as the flushing filter element. It is easy to retain dirt, sediment, collagen, bacteria, etc., and remain in the ultrafiltration membrane. The filter membrane cannot be cleaned, and a large amount of residual dirt in the filter element will breed bacteria, causing a vicious circle. After a period of use, other filter elements will be affected, so that other filter elements will also breed bacteria and form a variety of pathogenic bacteria. Since then, the originally clean water purifier has become a source of secondary pollution, seriousl...

AI Technical Summary

Problems solved by technology

[0002] At present, most water purifiers use pp cotton or ultrafiltration membrane as the cleaning filter element, and pp cotton and ultrafiltration membrane are used as the filter element for flushing, and dirt, sediment, collagen, bacteria, etc. are easily left in the ultrafiltration filter element. The inside of the filter membrane cannot be cleaned, and a large amount of residual dirt will breed bacteria in the filter element, resulting in a vicious cycle. After a period of use, it will affect other filter elements, causing other filter elements to breed bacteria and form a variety of pathogenic bacteria. Later, the originally clean water purifier has become a secondary pollution source, seriously endangering the health of users
