Description
Technical field
The present invention relates to a kind of garden furniture, more particularly to a kind of irrigation system.
Background technology
At present, in the construction of garden landscape, often trees is combined with lawn and built, in the prior art to this
The irrigations of lawn and trees it is general using sprinkling irrigation by the way of, sprinkling irrigation one side can allow water to compare waste, in addition, soil surface can allow
Compare moist, it is inconvenient.In order to economize on water, it can be carried out using slight irrigation.Slight irrigation is as desired, by pipe-line system with installing
Douche on final stage pipeline, by water and nutrient with less flow, is delivered directly near plant root uniformly, exactly
A kind of irrigation method of soil.And this micro irrigation technology is typically used in the plantation of gardens and crops.
Publication No. CN106069619A Chinese patent discloses a kind of using straw as agricultural crop straw as carrier
Slight irrigation underground heat and ventilation water-saving system, are fed the water into underground by micro irrigation pipe, so as to realize sub-irrigation, reach the mesh of water saving
, likewise, the system can be carried out to the irrigation on lawn, but, it is necessary to which pipe fitting is embedded to during actual use
Below ground, and open up apopore and irrigated, and easily cause pipe fitting to be blocked during irrigation, at this time, it may be necessary to
Pipe fitting is dug out, being repaired or being changed can allow system to work on, this system is when safeguarding, it is necessary to which pipe fitting is dug
Go out and carry out again, operate cumbersome, it is necessary to improve.
The content of the invention
It is an object of the invention to provide a kind of irrigation system, it can extract inner tube from outer tube out, so that internally blockage
When be convenient for changing.
The present invention above-mentioned technical purpose technical scheme is that：
A kind of irrigation system, including water inlet component and irrigation assembly, the irrigation assembly include sparge pipe and installed in
