Water purifier capable of adjusting water quality

Abstract

The invention discloses a water purifier capable of adjusting the water quality. The water purifier comprises a first-stage direct drinking water filtering tank (1) and a reverse osmosis filtering tank (3) which are sequentially serially connected between a water inlet (5) and a water outlet (6), wherein a direct drinking water outlet (7) is separately connected to the outlet of the first-stage direct drinking water filtering tank (1), and a bypass pipeline capable of adjusting the water quantity is connected between the inlet and outlet of the reverse osmosis filtering tank in parallel. According to the water purifier capable of adjusting the water quality, multiple types of water can be produced, and ultra-filtered water can meet the large-volume water demand of vegetable washing and cooking in a kitchen of a family; water subjected to reverse osmosis can meet the demand of water drinking of a family or department; ultra-filtered and reverse osmosis mixed water can be used for adjusting the hardness of water generated through reverse osmosis, so that the water subjected to reverse osmosis is moderate in hardness, not only is suitable for being drunk for a long time without generating water scale to block a water appliance, but also is used for meeting the demands of direct drinking, tea making and milk mixing in the family; reverse osmosis concentrated water can be used for mopping the floor, watering the flower and flushing the toilet. The water purifier is flexible and convenient to use, and capable of meeting multiple demands of a user.

Description

technical field [0001] The invention relates to a water purifier, in particular to a water purifier capable of adjusting water quality. Background technique [0002] With the increasingly serious pollution of tap water, people can no longer drink tap water directly and need to purify the tap water. The key components of water purifiers currently on the market are filter elements, which can be divided into microfiltration, ultrafiltration, nanofiltration, and reverse osmosis according to the filtration level. [0003] The filter element of microfiltration can intercept large impurities such as suspended solids, but cannot filter organic matter and dissolved solids. Common PP cotton and activated carbon belong to microfiltration; it is generally used for pre-filtration of reverse osmosis water purifiers and ultrafiltration water purifiers , to protect ultrafiltration membranes and reverse osmosis membranes. [0004] The purification of water by ultrafiltration membrane is ph...

Problems solved by technology

However, limited by the small amount of water produced by the reverse osmosis pure water machine, the water quality is too pure and not suitable for long-term drinking, which cannot satisfy consumers.

[0010] Existing water purifiers cannot take into account the large water production volume and high water quality requirements, let alone adjust the water quality. Therefore, it is an urgent need to develop a water purification equipment with large water production volume, good water quality, and the ability to adjust water quality according to demand. question
