NOVELTY - A solar water heating device comprises shell A (15) having heat preservation layer (1), and shell B (16) having strong magnetic material layer and insulating layer. The center of magnetic material layer has a water inlet pipe (4) that is against one end of a stainless steel screen plate (5). The stainless steel screen plate has shell C (17) having a silicon particle crystal layer (6), mineralizing ball layer (7), energy active calcium layer (8), medical stone layer (9), and water removing layer (10), which are provided with a stainless steel filter screen (11).    USE - Device for heating solar water.    ADVANTAGE - The device adopts 6 layers of filter purifying material structure and has anti-scaling performance, strong sterilization, good bacteriostasis performance, more complete magnetization, and quick action.    DETAILED DESCRIPTION - A solar water heating device comprises shell A (15) having heat preservation layer (1), and a shell B (16) having a strong magnetic material layer and insulating layer. The magnetic material layer is provided with a plastic partition. The center of magnetic material layer has a water inlet pipe (4) that is extended out of the magnetic material layer. The water inlet pipe is against one end of a stainless steel screen plate (5). The stainless steel screen plate has a shell C (17) having a silicon particle crystal layer (6), mineralizing ball layer (7), energy active calcium layer (8), medical stone layer (9), and water removing layer (10), which are provided with a stainless steel filter screen (11). The dirt water layer and the other end of the stainless steel filter screen and the other end of silicon crystal grain layer are connected with stainless steel screen plate and stainless steel liner (12) through one-way valve (13). The other end of the stainless steel inner container is provided with sieve holes (14).    DESCRIPTION OF DRAWING(S) - The drawing is a schematic view of the solar water heating device.
