Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0044] Embodiment 1:

[0045] This embodiment provides a rainwater collection and recycling device, comprising:

[0046] The water storage component comprises a water storage tank 1 for storing water, a collection component for collecting rainwater, and a treatment component for treating rainwater, and the water storage tank 1 is installed at a high position;

[0047] An irrigation assembly 2, which is installed at a low position and is provided in plurality, and is used for watering the garden landscape;

[0048] The main pipeline 3 is connected to the water storage tank 1, and a water pump 8 is provided between the main pipeline 3 and the water storage tank 1;

[0049] There are multiple branch pipes 4, which are respectively used to connect the main pipe 3 and the multiple nozzles 60;

[0050] Among them, a plurality of irrigation components 2 are provided with a water storage chamber 5 and a sprinkler assembly 6;

[0051] Meanwhile, the collection components and the processing components are both existing technologies and will not be elaborated here, and the distribution of the main pipeline 3 and the branch pipeline 4 needs to be arranged from high to bottom from beginning to end.

[0052] It can be seen from this embodiment that by setting the water storage tank 1 of the water storage assembly at a high position instead of burying it underground, the cleaning and maintenance of the water storage tank 1 are more convenient, ensuring the service life and the treatment effect and application effect of rainwater;

[0053] The irrigation assembly 2 for watering the garden landscape is arranged at a low position, so that when the water storage tank 1 is transporting water to the irrigation assembly 2, only a single water pump 8 is needed to form a continuous water flow through the main pipe 3 and the branch pipe 4 between the water storage tank 1 and the water storage chamber 5 in the early stage, and then the water pump 8 can be turned off, that is, the water storage tank 1 is prompted to replenish water to the irrigation assembly 2 through the siphon effect, on the one hand, the use of the irrigation pump is reduced, and the power consumption is saved, and on the other hand, the pressure of the siphon water flow is increased by the height difference between the water storage tank 1 and the water storage chamber 5, thereby avoiding the need to set up multiple irrigation pumps and reducing the occupied area;

[0054] Specifically, the water tank 1 can be set on the roof of a high-rise building to increase the height difference and thereby increase the pressure of the siphon water flow, thereby avoiding the need to set up multiple irrigation pumps, and multiple main pipes 3 can be set as needed, that is, each main pipe 3 is supplied by multiple branch pipes 4, so as to meet a larger irrigation area.

[0055] Embodiment 2:

[0056] This embodiment provides a rainwater collection and recycling device, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0058] The inner wall 200 is provided with an overflow port 202 , the outer wall 201 is provided with a drain hole 203 , and the branch pipe 4 passes through the outer wall 201 and the inner wall 200 and extends to below the liquid level in the water storage chamber 5 .

[0059] It can be seen from the present embodiment that, through the arrangement of the inner wall 200 and the outer wall 201, when too much supplied water or rainwater enters the inner wall 200 of the cylinder 20, it can be discharged in sequence through the overflow port 202 and the drain hole 203 to keep the water level in the water storage chamber 5 stable, and the branch pipe 4 is extended to between the liquid levels in the water storage chamber 5, so as to ensure that a continuous water flow is formed between the water storage tank 1 and the water storage chamber 5, thereby ensuring the siphon effect.

[0060] Embodiment 3:

[0061] This embodiment provides a rainwater collection and recycling device, which, in addition to the technical solutions of the above embodiments, also has the following technical features. The nozzle assembly 6 includes:

[0063] The water pump device 61 is arranged in the water storage chamber 5, and the water outlet is connected to the tail of the nozzle 60 through a water pipe 62;

[0064] The size of the mounting hole 204 is larger than the size of the water pumping device 61, so that the water pumping device 61 is placed in the mounting hole 204;

[0065] At the same time, the water pumping device 61 can adopt a small submersible pump 8 powered by a 12V voltage.

[0066] It can be seen from this embodiment that by setting the nozzle 60 at the top of the cylinder 20 and installing the water pumping device 61 in the water storage chamber 5, the nozzle 60 and the water pumping device 61 are arranged vertically, which facilitates burying the cylinder 20 underground, reduces horizontal occupied space, and reduces damage to the garden lawn.

[0071] The annular protrusion 601 and the cylinder 20 can be connected by bolts, and the bolts are wrapped with raw tape to improve the sealing performance and avoid corrosion of the threads on the bolts.

[0072] It can be seen from this embodiment that the annular protrusion 601 facilitates the installation and support of the nozzle 600, thereby improving the installation strength and stability of the nozzle 600, while the dispersed structure enables the water pumping device 61 to spray in a dispersed manner, thereby increasing the spraying area and improving the irrigation efficiency and effect.

[0083] The multiple water outlet holes 603 can also be used as water inlet holes, so that part of the rainwater is filtered through the filter net 604 and enters the cylinder 20 for temporary storage for the next irrigation water. The multiple water outlet holes 603 opened upward can increase the spraying distance and improve the irrigation effect.

[0084] Embodiment 7:

[0085] This embodiment provides a rainwater collection and recycling device, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0086] The nozzle 600 is provided with a counterbore 605 at the axis center of the expanded portion, and a lamp holder 606 is installed in the counterbore 605;

[0099] It can be seen from this embodiment that the liquid level in the water storage chamber 5 is fed back by the liquid level sensor to ensure that the liquid level in the water storage chamber 5 is at a set height and that the outlet end of the branch pipe 4 is always below the liquid level;

[0100] The control unit can control the opening and closing of the siphon by controlling the start and stop of the solenoid valve 7, and the solenoid valve 7 is set below the installation height of the water storage tank 1, so that after the water pump 8 starts the siphon effect, the opening and closing of the solenoid valve 7 is used to control the temporary opening and closing of the siphon;

[0101] Specifically, when any one end or both ends of the main pipe 3 or the branch pipe 4 leave the liquid surface, that is, the liquid level drops too much, the siphon phenomenon stops, and the next start needs to use the water pump 8 to regenerate the siphon effect.
