The invention discloses a solar convenient water purification tank group which is composed of a tank body, a tank cover, a water purifier inner tank
assembly, a water purifier power distribution
assembly and an intelligent power supply module, the water purifier inner tank
assembly and the water purifier power distribution assembly are installed in the tank body, and a tank body partition plate is arranged between the water purifier inner tank assembly and the water purifier power distribution assembly; the water purifier inner tank assembly comprises
reverse osmosis filter elements, a water suction pump, a diaphragm
booster pump, a water purifier inner tank assembly bottom plate and a heater; the
reverse osmosis filter elements are connected with the water suction pump through
filter element connecting frames, the
reverse osmosis filter elements are mutually connected through
filter element connecting frames, the reverse
osmosis filter elements and the bottom end of the water suction pump are installed on the water purifier inner tank assembly bottom plate through
filter element supports, a water inlet is formed in one end of the heater, and the water inlet is connected with water outlets of the reverse
osmosis filter elements through pipelines; and the diaphragm
booster pump is mounted on the water purifier inner tank assembly bottome plate through bolts. The solar convenient water purification tank group internally has heat preservation and heating functions, and can be used at continuous low temperature.
