Description

Household water purifier with automatic sterilization and preservation functions

Technical Field

The utility model relates to a water purification technology field especially relates to an automatic select domestic water purifier of fresh-keeping function of degerming.

Background

Water is a source of life, and drinking water quality directly affects the health of people. Drinking high-quality water has become a symbol of social civilization and progress, and is also a target pursued by people in China. At present, one fourth of people in China drink water which does not meet the sanitary standard, and the water pollution is a main environmental problem in China. With the improvement of living standard, people are more concerned about drinking water. At present, the sources of urban drinking water are mainly tap water and purified water. Tap water is supplied from a water supply company in a centralized manner, and generally, the quality of water quality is determined by the quality of water supplied in a centralized manner, and thus, the quality cannot be selected by an individual. In the past, purified water drunk by people is barreled purified water used on a water dispenser and bottled purified water drunk daily. Barreled drinking water that people used has a lot of sanitary aspects's problems, say that the reciprocal use of vat, can't brush the bucket interior totally, has a lot of illegal businessmen to retrieve old bucket and do the bucket again, generally calls black bucket, and black bucket flows into market and causes harmful effects for people's physical and mental health, and kneck and air direct contact have so produced secondary pollution behind the drinking water machine is put to the barreled water.

In recent years, in order to improve the quality and safety of drinking water, more and more water purifying devices enter thousands of families, and a household water purifier is a water purifying device for families, which can be used by users to drink purified water in 24 hours. The water purifier has the advantages that the water purifier can be idle in field time due to different drinking habits of people, so that the household water purifier has a plurality of defects in use, for example, when the household water purifier is in a standby and non-operating state for a long time, the purified drinking water in the system can not be guaranteed to keep aseptic freshness at all times, because when the household water purifier is not used for a long time, the purified water accumulated in the water purifying barrel accumulation pipeline is in a static state and can not be discharged in time, the accumulated water can nourish the propagation of bacteria after being placed for a long time, and the water quality and the freshness are influenced; or when the residents take water, air enters the water purifying barrel, secondary pollution is caused to drinking water, bacteria are bred, the water quality is influenced, and even the potential safety hazard of drinking water is brought.
