Domestic water supply system with water purification function

Abstract

The invention discloses a domestic water supply system with a water purification function. The domestic water supply system comprises an irrigation device, a pressurizing cylinder, a buckle, a pressurizing assembly, a ball valve, a connecting rod, a valve closing assembly, a pressing rod, a driving piece and a floating ball. The irrigation device comprises a liquid channel, a first piston, a firstspring, an end cover, a middle cavity and a plurality of irrigation assemblies installed at the bottom of the middle cavity. A sealing groove is formed in the first piston; a water inlet and a nutrient solution pouring port are formed at the top of the pressurizing cylinder, a water outlet is formed in the side face, and multiple guide rails are fixed to the outer wall; a plurality of notches areformed in the nutrient solution pouring port; and domestic water in a high-rise building is purified and then used for cultivating green plants in a roof garden, the irrigation assemblies are pushedby water pressure to be inserted into the ground to loosen soil, water flow flows into the soil along the irrigation assemblies, and the soil is wetted. Compared with an existing manual water sprayingirrigation manner, the system is more suitable for irrigation of roof gardens, and the irrigation effect is enhanced.

Description

technical field [0001] The invention belongs to the technical field of urban domestic water supply applications, in particular to a domestic water supply system with water purification function. Background technique [0002] Roof gardens refer to gardens built in the form of greening on the roof. Roof gardens not only have excellent cooling and heat insulation effects, but also can beautify the environment, purify the air, improve local microclimates, enrich the city's pitching landscape, and compensate for the greenery occupied by buildings. The ground, which greatly improves the green coverage of the city, is a roof form worthy of vigorous promotion; in the existing technology, the roof garden needs to be taken care of manually.

[0002] Roof gardens refer to gardens built in the form of greening on the roof. Roof gardens not only have excellent cooling and heat insulation effects, but also can beautify the environment, purify the air, improve local microclimates, enrich the city's pitching landscape, and compensate for the greenery occupied by buildings. The ground, which greatly improves the green coverage of the city, is a roof form worthy of vigorous promotion; in the existing technology, the roof garden needs to be taken care of manually. Since the roof garden is built on the roof, large-scale land reclamation and irrigation facilities cannot Most of the roof gardens rely on artificial watering, and some high-rise buildings also use pipes and nozzles to water the green plants, but these methods are only watering the green plants, and there is no special loosening equipment for the planted soil. Under long-term use, the air permeability of the soil decreases, which affects the growth of green plants; at the same time, because the roof is full of sunlight, the water sprayed on the surface of the soil is easy to evaporate and lose, so the irrigation effect is not good
