Rainwater recycling device

Abstract

The invention provides a rainwater recycling device, and belongs to the field of resource recycling. The rainwater recycling device comprises a rainwater receiving air bag, an inflation mechanism and a rainwater receiving box, the inflation mechanism is connected with the rainwater receiving air bag and used for inflating the rainwater receiving air bag to enlarge the rainwater receiving air bag, a water inlet groove is formed in the middle of the rainwater receiving air bag and connected with the rainwater receiving box, and rainwater received by the rainwater receiving air bag enters the rainwater receiving box through the water inlet groove. The rainwater recycling device can quickly recycle more rainwater, reduces waste of rainwater resources during short-time rainfall, has heat insulation performance, and effectively avoids rainwater deterioration caused by temperature rise in summer; and meanwhile, the rainwater recycled in winter can be effectively prevented from being frozen, normal use of the recycled rainwater is ensured, and the rainwater recycling device is practical, efficient, energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the field of resource recovery, in particular to a rainwater recovery device. Background technique [0002] In order to save resources, rainwater recovery devices are used in housing construction to collect and filter rainwater for reuse. The recovered rainwater can be used for residents to wash vegetables and water flowers. However, when the current rainwater recovery device used in house construction is in use, its rain outlet cannot be expanded, and the rainwater recovery speed is relatively slow. When the rainfall time is short, it cannot receive more rainwater, which in turn causes a waste of rainwater resources. And at present, when the rainwater recovery device is in use, the rainwater in summer is exposed to the sun for a long time, and the temperature of the rainwater will rise, which will undoubtedly increase the reproduction speed of bacteria in the rainwater. When the number of bacteria increases to a certain extent...

AI Technical Summary

Problems solved by technology

However, when the rainwater recovery device used in housing construction is in use, the rainwater outlet cannot be expanded, and the rainwater recovery speed is slow. When the rainfall time is short, it cannot receive more rainwater, which in turn causes a waste of rainwater resources.

And at present, when the rainwater recovery device is in use, the rainwater in summer is exposed to the sun for a long time, and the temperature of the rainwater will rise, which will undoubtedly increase the reproduction speed of bacteria in the rainwater. When the number of bacteria increases to a certain level, the rainwater will deteriorate. If rainwater is used to wash vegetables and then eaten by people, it will affect people's health

And in winter, because the device cannot heat the water, the rainwater is prone to freezing, which makes the rainwater in winter unable to be used normally.
