Description

Technical Field

[0001] The utility model relates to the field of rainwater collection devices, in particular to a building rainwater collection device with a filtering function. Background Art

[0002] Modern buildings for high-end residents are designed with rooftop terraces, open-air balconies, etc. Some buildings with shops on the first floor will also have a large platform structure extending outward on the second floor. Because of the existence of these terraces and platform structures, water will accumulate on the terraces in rainy and snowy weather. Therefore, the corners of these terraces will be designed with drainage pipes extending downstairs to drain the rainwater on the platform.

[0003] For residences with terraces and platforms, the rainwater discharged through the drainage pipes is generally relatively clean and can be used for activities such as raising fish and planting flowers. However, there is currently no device that can collect this rainwater. All rainwater is directly discharged and cannot be fully utilized. If residents plant flowers or raise fish on the platform, they can only choose to use household tap water, which results in a certain amount of waste.

[0004] Therefore, in view of the fact that the rainwater on the terrace of the above-mentioned building directly flows down the drain pipe and cannot be utilized, resulting in a waste of resources, a rainwater collection device that can be used in the drain pipe of the building platform can be designed to accumulate a certain amount of rainwater for simple life activities. Utility Model Content

[0005] In order to overcome the problem that rainwater on the terrace of the building flows directly into the drainage pipe and cannot be utilized, resulting in a waste of resources.

After the rubber plug is pushed into the filter cartridge, the magnetic metal sheet is adsorbed on the magnetic ring. When pouring water, the rubber plug will not fall off from the filter cartridge due to the gravity and impact force of the water flow, thereby ensuring the tightness of the water outlet channel.

[0012] Preferably, the water outlet terminal is a shower head; the water inlet end of the shower head is fixedly connected with a through pipe covered with rubber, the through pipe is plugged and fixed on the upper end of the extension pipe, and rainwater in the water collecting pipe first enters the rubber plug, flows into the shower head along the extension pipe and is finally discharged, and is used to water the flowers and plants on the building platform.
