[0003] In the circulating water-saving device for landscaping, impurities are likely to accumulate in the underground collection water tank for various reasons. For example, when rainwater flows through the garden surface, it will wash soil, leaves, grass clippings and other substances into the water tank, and these impurities may cause frequent blockages of the sprinkler heads. Content of the Utility Model

[0004] The purpose of the utility model is to propose a circulating water-saving device for landscaping in view of the problems existing in the background technique.

A plurality of protrusions are provided on the drive block. A support seat is fixedly mounted in the shunt pipe. A transmission rod is rotatably mounted in the support seat. One end of the transmission rod is rotatably mounted with a first roller abutting against the drive block, and the other end of the transmission rod is rotatably mounted with a second roller. A sliding cylinder is fixedly mounted in the nozzle. A sliding rod is slidably mounted in the sliding cylinder. A return spring is fixedly mounted in the sliding cylinder, and the other end of the return spring is fixedly connected to the sliding rod. A connecting plate is fixedly mounted on the sliding rod. A plurality of pressing heads are fixedly mounted on the connecting plate. The second roller abuts against the connecting plate.

[0016] In summary, the present application includes at least one of the following beneficial technical effects:

[0017] When water flows through the second scroll blade, it will drive the sliding rod to move towards the direction close to the spray opening, so that the pressing head enters the inside of the spray opening, and thus the impurities inside the spray opening can be extruded through the pressing head, effectively preventing the gradual increase of impurities accumulated inside the spray opening and ultimately causing the blockage of the spray opening. It can reduce the maintenance work of the sprinkler by garden workers and improve the evenness of water spraying when the sprinkler is working.

[0018] When the pressing head enters the inside of the spray opening, water can be discharged to the outside of the nozzle through the flow holes. At this time, since the inner diameter of the flow hole is smaller than that of the spray opening, the speed of the water sprayed through the nozzle will increase, so that the range of the spray pipe fluctuates, and thus the spraying range can be expanded while the sprayed water is more evenly distributed.

Specific embodiments

[0029] The technical solutions of the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. Embodiment

[0030] As Figure 1-2 And Figure 7As shown in the figure, a circular water-saving device for landscaping proposed by the utility model includes an underground water tank and an irrigation system. The underground water tank is used to store rainwater, tap water or treated water to provide water source for irrigation. Through the irrigation system, the water in the underground water tank can be pumped out and sprayed onto the soil in the garden (this is the prior art and will not be elaborated here). A plurality of spray heads are installed on the irrigation system. The spray head includes a base 1, and a water pipe 101 is detachably installed on the base 1. The water pipe 101 is connected to the irrigation system. The water in the underground water tank will enter the base 1 through the water pipe. A sealing piece 5 is fixedly installed at the connection between the base 1 and the water pipe 101, and a filter screen 501 is fixedly installed on the sealing piece 5. The water entering the interior of the base 1 can be preliminarily filtered through the filter screen 501.

[0031] As Figure 1-2 shown in the figure, this embodiment further includes a rotating cylinder 2 rotatably installed on the base 1. A plurality of nozzles 204 are fixedly installed on the rotating cylinder 2, and a plurality of spray openings 205 are provided on the nozzles 204. The water entering the base 1 will flow into the interior of the nozzles 204 and finally be sprayed out through the spray openings 205. A connecting cylinder 201 is fixedly installed on the rotating cylinder 2, an end cover 202 is fixedly installed on the connecting cylinder 201, a plurality of shunt pipes 203 are fixedly installed on the end cover 202, and the nozzles 204 are fixedly installed on the shunt pipes 203. The water entering the base 1 will successively enter the interior of the nozzles 204 through the rotating cylinder 2, the connecting cylinder 201, the end cover 202 and the shunt pipes 203.

[0032] As Figure 2-3 shown in the figure, in this embodiment, a rotating mechanism is installed in the rotating cylinder 2. The rotating mechanism drives the rotating cylinder 2 to rotate under the action of water flow. The rotating mechanism includes a first scroll blade 3 fixedly installed in the rotating cylinder 2. When the water flow enters the interior of the base 1, the water flow drives the first scroll blade 3 to rotate. The rotating first scroll blade 3 will drive the rotating cylinder 2 to rotate, and then drive a plurality of nozzles 204 to rotate, so that the water sprayed by the nozzles 204 covers a larger range and can evenly disperse the water on the soil.

[0033] As Figure 2-6 and Figure 9As shown in the figure, this embodiment further includes a self-cleaning mechanism. The self-cleaning mechanism is installed inside the rotating cylinder 2 and periodically enters the inside of the spray nozzle 205 under the action of water flow. The self-cleaning mechanism includes a second scroll blade 4 rotatably installed on the end cover 202. A driving block 401 is coaxially and fixedly installed on the second scroll blade 4. Multiple protrusions are provided on the driving block 401. A support seat 402 is fixedly installed inside the shunt pipe 203. A transmission rod 403 is rotatably installed inside the support seat 402. One end of the transmission rod 403 is rotatably installed with a first roller 404 that abuts against the driving block 401. The other end of the transmission rod 403 is rotatably installed with a second roller 405. A sliding cylinder 406 is fixedly installed inside the nozzle 204. A sliding rod 407 is slidably installed inside the sliding cylinder 406. A return spring 408 is fixedly installed inside the sliding cylinder 406. The other end of the return spring 408 is fixedly connected to the sliding rod 407. A connecting plate is fixedly installed on the sliding rod 407. Multiple pressing heads 409 are fixedly installed on the connecting plate. The second roller 405 abuts against the connecting plate. When water flow passes through the second scroll blade 4, the water flow will drive the second scroll blade 4 to rotate. The rotating second scroll blade 4 will drive the driving block 401 to rotate. The rotating driving block 401 will squeeze the first roller 404. Through the first roller 404, the transmission rod 403 will be driven to move. The moving transmission rod 403 will drive the second roller 405 to move. The pressure exerted on the connecting plate by the second roller 405 can drive the sliding rod 407 to move in the direction close to the spray nozzle 205, so that the pressing head 409 enters the inside of the spray nozzle 205, and thus the impurities inside the spray nozzle 205 can be extruded through the pressing head 409, effectively preventing the gradual increase of impurities accumulated inside the spray nozzle and finally preventing the phenomenon that the spray nozzle 205 is blocked. When the first roller 404 detaches from the driving block 401, the return spring 408 will reset the transmission rod 403 and the pressing head 409.

[0034] Among them, the connecting plate is in a parallel position with multiple spray nozzles 205. A flow hole 410 is provided on the pressing head 409. When the pressing head 409 enters the inside of the spray nozzle 205, water flow can be discharged to the outside of the nozzle 204 through the flow hole 410. At this time, since the inner diameter of the flow hole 410 is smaller than that of the spray nozzle 205, according to the continuity equation, the flow rate (volume flow rate) of the fluid in the pipeline is constant. The flow rate Q is determined by the product of the cross-sectional area A of the pipeline and the fluid velocity v, that is, Q = A×v. When water flows from a large-diameter pipeline into a small-diameter pipeline, the cross-sectional area decreases. To keep the flow rate unchanged, the fluid velocity must increase. Therefore, the velocity of the water sprayed out through the nozzle 204 will increase at this time, so that the range of the spray pipe fluctuates, and thus the spraying range can be expanded while making the sprayed water more evenly distributed.

[0035] As Figure 2 and Figure 8As shown in the figure, in this embodiment, a push plate 6 is slidably installed in the base 1. A driving rod 601 is fixedly installed on the push plate 6. The driving rod 601 penetrates the bottom of the base 1 and extends to the outside of the base 1. A compression spring 602 is fixedly installed on the base 1. The other end of the compression spring 602 is fixedly connected to the driving rod 601. A sealing pressure ring 603 is fixedly installed on the base 1. The driving rod 601 can be pressed to drive the push plate 6 to slide inside the base 1. The space inside the base 1 is instantaneously compressed by the rapidly moving push plate 6, so that the water pressure inside the base 1 rapidly increases, which can apply a greater thrust to the second scroll vane 4. Thus, the indenter 409 can apply a greater thrust to the impurities inside the spray nozzle 205. When the water pressure of the base 1 itself cannot clean the impurities inside the spray nozzle 205, manual pressure boosting can be carried out.

[0036] Working principle: The underground water tank is used to store rainwater, tap water or treated water to provide water source for irrigation. The water in the underground water tank can be pumped out through the irrigation system and enter the base 1. The water entering the base 1 will successively pass through the rotating cylinder 2, the connecting cylinder 201, the end cover 202 and the shunt pipe 203 and enter the inside of the nozzle 204, and finally be sprayed out through the spray nozzle 205.

[0037] When the water flow enters the inside of the base 1, the water flow drives the first scroll vane 3 to rotate. The rotating first scroll vane 3 will drive the rotating cylinder 2 to rotate, and then drive a plurality of nozzles 204 to rotate, so that the water sprayed by the nozzles 204 covers a larger range and the water can be evenly dispersed on the soil.

[0038] When the water flow passes through the second scroll vane 4, the water flow will drive the second scroll vane 4 to rotate. The rotating second scroll vane 4 will drive the driving block 401 to rotate. The rotating driving block 401 will squeeze the first roller 404. The transmission rod 403 will be driven to move through the first roller 404. The moving transmission rod 403 will drive the second roller 405 to move. The pressure applied to the connecting plate by the second roller 405 can drive the sliding rod 407 to move towards the direction close to the spray nozzle 205, and then the indenter 409 enters the inside of the spray nozzle 205. Thus, the impurities inside the spray nozzle 205 can be extruded by the indenter 409, which can effectively prevent the impurities accumulated inside the spray nozzle from gradually increasing and finally causing the phenomenon that the spray nozzle 205 is blocked. When the first roller 404 detaches from the driving block 401, under the action of the return spring 408, the transmission rod 403 and the indenter 409 will be reset.

[0039] The above specific embodiments are only several alternative embodiments of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
