Multifunctional domestic water purifier

Abstract

The invention relates to a multifunctional household water purifier, which comprises a shell, wherein a filter screen is respectively arranged on the top and at the bottom of the inside of the shell; various filter materials are filled between the upper filter screen and the lower filter screen; a water inlet pipe is arranged on the top of the shell, and a water outlet pipe is arranged at the bottom of the shell; the outer end of the water outlet pipe is connected with a stop valve; the top end of the water inlet pipe is connected with one water outlet of a triple switch valve; a back flushing water inlet pipe is connected with the other water outlet of the triple switch valve; the tail end of the back flushing water inlet pipe is communicated with the water outlet pipe on the lower part of the water purifier; a water inlet of the triple switch valve is directly connected to a water supply pipe; a blow-off pipe is also arranged on the water inlet pipe at the top end of the shell of the water purifier; and a stop valve is arranged on the blow-off pipe. The multifunctional household water purifier can select pertinent filter materials according to the local water quality conditions, can effectively filter out impurities and pollutants in inlet water, can always maintain the high-efficiency filter effect of a filter as long as a back flushing program is often performed for the multifunctional household water purifier is provided with a back flushing device, and is suitable to be used by residents.

Description

【Technical field】 [0001] The invention relates to a water purifier, in particular to a multifunctional household water purifier. 【Background technique】 [0002] At present, the vast rural areas have caused serious water pollution due to the widespread use of chemical fertilizers, pesticides, and weir and pond silt. In addition, there are heavy metals or minerals in groundwater in many places that exceed the standard (such as magnesium oxide, calcium oxide, and iron oxide), which seriously affects The quality of people's living water is seriously threatened, and even seriously threatens people's health. Therefore, farmers' friends urgently need a household water purifier that can purify various water qualities. [0003] At present, water heaters (such as solar water heaters, electric water heaters, and liquefied gas water heaters) are widely used in urban and rural areas.

Problems solved by technology

[0002] At present, the vast rural areas have caused serious water pollution due to the widespread use of chemical fertilizers, pesticides, and weir and pond silt. In addition, there are heavy metals or minerals in groundwater in many places that exceed the standard (such as magnesium oxide, calcium oxide, and iron oxide), which seriously affects The quality of people's living water is seriously threatened, and even seriously threatens people's health. Therefore, farmers' friends urgently need a household water purifier that can purify various water qualities.

[0003] At present, water heaters (such as solar water heaters, electric water heaters, and liquefied gas water heaters) are widely used in urban and rural areas. Due to water quality problems, most users report that after a year or a half, the use of water heaters has significantly declined, and some even cannot be used. It is the trouble caused by the scale produced by the minerals and heavy metals in the water quality. If the problem of water quality purification cannot be solved, it will bring many difficulties to the popularization and application of many technological products such as water heaters.

[0004] At present, in the market, especially the water purifiers produced by southern enterprises generally adopt filter element filtration and purification, not only the filter material needs to be replaced frequently, but also the purification effect is single, only the treated tap water can be repeatedly filtered, and only the obvious suspension little effect

The product structure adopts plastic products, and long-term use will also cause secondary pollution to water quality

No purification effect on heavily polluted surface water and harmful substances
