Water purifier for adjusting water production TDS value

Abstract

The invention relates to a water purifier and discloses a water purifier for adjusting a water production TDS value. The water purifier comprises a composite filter element, an ultrafiltration deviceand a purification device, a tap water inlet is formed in the composite filter element, and the ultrafiltration device and the purification device are connected to a water outlet of the composite filter element through a pipe; the ultrafiltration device comprises an ultrafiltration film filter element, and a water outlet of the ultrafiltration film filter element is connected with a TDS adjuster through a pipe; the purification device comprises an RO film filter element and a rear-arranged activated carbon filter element which are connected through a pipe in the direction of water flow in sequence, a water inlet electromagnetic valve, a water inlet TDS probe and a booster pump are arranged on a pipe which is connected with the composite filter element and the RO film filter element in sequence, and the TDS adjuster and the rear-arranged activated carbon filter element are connected to a water outlet TDS probe through pipes. According to the water purifier for adjusting the water production TDS value, the function of adjusting the water production TDS value is achieved.

Description

technical field [0001] The invention relates to a water purifier, in particular to a water purifier for adjusting the TDS value of produced water. Background technique [0002] At present, the terminal direct drinking water machines on the market mainly include ultrafiltration machines, nanofiltration machines, and reverse osmosis pure water machines. Users can only choose one of them when choosing machines according to different water quality needs. They often drink pure water and minerals. Water is not the best choice for human health. Although the latest dual-outlet water purifier can realize double selection of water quality, it can only choose one of ultra-filtered water and pure water, and it is impossible to check the TDS value of the produced water. Effective control. Contents of the invention [0003] The purpose of the present invention is to provide a water purifier for adjusting the TDS value of produced water, so as to realize the function of adjusting the TD...
