The specific implementation process is as follows: the solar water heater is arranged on a roof through a base 1 and is positioned in a windy and sandy area; the wind sand enters the dust collection box 4 through the chute 51 and then falls on the dust collection plate 540 for accumulation; meanwhile, the chute 51 can increase the flowing speed of the wind, and the dust collecting plate 540 drives the rotary cylinder 53 to rotate under the action of the air deflector 51; at this time, the embedding ball 78 moves along the surface of the arc groove 74 under the action of inertia; the embedding ball 78 moves to the speed reducing block 75 and then is embedded and limited with the embedding groove 76; then, the magnetic roller 58 abuts against the dust collecting block 56, and the further magnetic roller abuts against the dust collecting block 56; the dust collecting block 56 is made magnetic to adsorb dust; then the dust collection block 56 is reset under the action of the dust collection torsion spring 59; at this time, the dust falls from the dust collecting plate 540 onto the pressing plate 81 with the lapse of time; the squeeze plate 81 slowly becomes heavy and starts moving downward; simultaneously, the unlocking roller 99 enters the unlocking tube 98; the slow first embedding ring 990 is butted with the first embedding groove 991, and meanwhile, the extrusion plate 81 is butted with the button 90; the motor 36 is started to drive, and the rotating wheel 35 starts to rotate; the rotating wheel 35 is driven to rotate, the synchronous belt 37 starts to operate, and the butt-joint block 39 is butted with the butt-joint hole 38; thereby driving the moving block 31 to start moving, and at the moment, the cleaning roller 32 moves along the surface of the heat collecting tube 24 to scrape off the sand on the surface of the heat collecting tube 24; after the cleaning roller 32 moves one stroke; the reset block 69 abuts against the boss 63 through the first limit plate 64; then the reset block 69 moves laterally against the traveling block 31 and further the abutment hole 38 is separated from the abutment block 39, at which time the reset block 69 is located in the upper traveling groove 61; then the moving block 31 starts to reset under the action of the moving spring 34; at the same time, the second cam 97 starts to abut against the first cam 97, moving the piston block 92 inside the pumping chamber 91; the generated air pressure slowly presses the squeegee 85; at this time, the scraper 85 is limited under the action of the elastic ring 87; as the air pressure increases, the elastic ring 87 is disengaged from the catching groove 88; at this time, the scraper 85 moves to scrape off the dust on the extrusion plate 81; meanwhile, the resisting block 995 resists against the unlocking block 992 along with the reset of the moving block 31, and drives the unlocking block 992 to unlock; further, the first embedding ring 990 is separated from the first embedding groove 991, and then the pressing plate 81 begins to reset, so that one cleaning is completed; after the water heater is used for a long time, the cleaning roller 32 can be manually detached to clean the sand in the silt groove 33.
