[0033] Embodiment 2

[0034] Reference Figs. 1-3 On the basis of Embodiment 1, an improved multi-stage solar interface water purification device is applied to the field of water treatment. In order to facilitate water inlet and fixation of the partition plate, a connecting plate 3 is fixedly arranged on one side of the top of the box body 1, and a plurality of water inlet pipes 4 are threadedly arranged through the connecting plate. The number and position of the water inlet pipes 4 correspond to the insertion holes 21 on the blocking ring.
