When the rainwater collection and purification device is used, the water collection tank 5 arranged at the top of the cabinet body 1 is utilized to effectively collect rainwater, the collected rainwater is filtered by the primary filter screen 6 to remove large-particle impurities in the rainwater, then the rainwater falls into the water collection tank 5 through the primary filter screen 6, secondary filtering treatment is effectively carried out on the rainwater under the action of the fine filter screen 7 to improve the rainwater purification effect, then the rainwater is guided into the water filter pipe 8 under the action of the guide plate 11, the rainwater is further subjected to tertiary filtering and purification treatment on the rainwater through the filler filtering area 21 in the water filter pipe 8, the filtered and purified rainwater falls into the retention area 22, and then the rainwater in the retention area 22 is guided into the water collection bag 10 to be collected and reserved for use under the action of the water pump 9, so that the recycling of water resources is realized; in addition, when the water in the stagnation area 22 is accumulated to the position of the second water level sensor 24, the timer 20 starts to operate, and when the water in the stagnation area 22 is not accumulated to the position of the first water level sensor 23 within a preset time, the controller 18 controls the drainage valve 26 to be opened, so that the water in the stagnation area 22 is drained through the drainage pipe 25; when the water in the stagnation area 22 is accumulated to the position of the first water level sensor 24 within a predetermined time, the controller 18 controls the water pump 9 to operate, and the water in the stagnation area 22 is guided to the water collecting bag 10 to be collected.
The foregoing is illustrative of the preferred embodiments of this invention, and it is to be understood that the invention is not limited to the precise form disclosed herein and that various other combinations, modifications, and environments may be resorted to, falling within the scope of the concept as disclosed herein, either as described above or as apparent to those skilled in the relevant art. And that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
