Description

Technical Field

[0001] This invention relates to the field of garden irrigation equipment technology, specifically to an agricultural garden irrigation device. Background Technology

[0002] Irrigation methods mainly include sprinkler irrigation, drip irrigation, flood irrigation, and seepage irrigation. Sprinkler irrigation mainly simulates natural rainfall by pressurizing water through pumps and pipes, and then spraying the water evenly into the air through nozzles, forming fine water droplets that fall to the ground. Drip irrigation delivers water and nutrients directly, slowly, and evenly to the soil around the roots of crops. Flood irrigation introduces water into the field over a large area, allowing it to flow and seep into the soil. The selection of agricultural and horticultural irrigation equipment needs to balance economy, efficiency, and sustainability.

[0003] When irrigating lawns in gardens, retractable sprinklers are often used. The water source for irrigation usually comes from surface water, such as rivers, lakes, and ponds near the garden. Surface water usually contains more impurities, and filters are usually used inside the sprinklers. However, more impurities may cause the filters to become clogged, affecting the flow of water. This may also cause a drop in water pressure inside the sprinklers, resulting in a narrower irrigation range and affecting the uniformity of irrigation. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an agricultural and garden irrigation device, including a sleeve, a spring sleeve slidably connected to the inner wall of the sleeve, a filter screen fixedly connected to the inner wall of the sleeve, and a sealing ring fixedly connected to the outer wall of the spring sleeve to prevent water from entering the top of the spring sleeve. An irrigation mechanism is provided with a lifting component that slides along the inner wall of the irrigation mechanism, and a spraying component is installed on the top of the irrigation mechanism. The lifting component is used to lift the spraying component. A sewage discharge mechanism, installed on the inner wall of the irrigation system, is used to flush out impurities from the filter screen; and The separation mechanism, located on the inner wall of the irrigation mechanism, is used to keep impurities in a suspended state. A fixing ring is fixedly connected to the inner wall of the sleeve, a spring ring is slidably connected to the inner wall of the fixing ring, and a blocking rod is slidably connected to the inner wall of the sleeve. The process involves connecting a sleeve to a water pipe and using an external water pump to pump water into the sleeve. The water flow propels the irrigation mechanism upwards to irrigate the garden lawn. When the pump stops, a wastewater discharge mechanism backwashes the filter screen to clean it and effectively prevent impurities from adhering to the filter screen's pores, causing blockage, reduced water flow, and a smaller irrigation area. Finally, a separation mechanism removes the impurities.

[0005] Preferably, the irrigation system includes: The lifting assembly is slidably installed between the outer wall of the lifting assembly and the inner wall of the sleeve, and is used to lift the spraying assembly. A spraying assembly, with its bottom fixed to the top of a spring sleeve, is used to spray water to irrigate the lawn; The operator connects the sleeve to the water pipe, and an external water pump pumps water into the sleeve. The water is filtered through a filter screen, and then the water flow lifts the spraying components to irrigate the lawn.

[0006] Preferably, the sewage discharge mechanism includes: The collection component is fixedly installed on the inner wall of the sleeve and is used to collect the impurities flushed out of the filter screen. The push component is fixedly installed on the inner wall of the sleeve and is used to discharge the collected impurities; When irrigation is complete and the water pump stops, the lifting component returns to its original position, squeezing the filtered water flow and backwashing impurities inside the filter screen. This prevents impurities from adhering to the filter screen, causing blockage, reduced water flow, and a shorter spray distance from the nozzle. When irrigation resumes, the water flow pushes the lifting component upward, which in turn discharges the collected impurities. This effectively prevents impurities washed out of the filter screen from accumulating inside the sleeve, causing them to re-adhere to the filter screen surface during subsequent irrigations.

[0007] Preferably, the separation mechanism includes: The striking component is slidably mounted on the inner wall of the sleeve via a slider, which is used to keep the impurities in the collection component in a suspended state. The sliding component includes a sliding ring that is slidably connected to the inner wall of the sleeve, and eleven spring rods are slidably connected to the inner wall of the sliding ring; Compression assembly, which is fixedly installed on the inner wall of the sleeve, is used to increase the thrust of the lifting assembly; When the pusher component rises, it also causes the striking component to rise, repeatedly striking the bottom of the collection component. This keeps the impurities collected by the collection component in a suspended state, effectively preventing impurities from settling at the bottom of the inclined collection ring. Some solid impurities may adhere to the bottom of the inclined collection ring, making it difficult for the water flow to remove them, thus reducing impurity deposition. At the same time, by compressing the component, the back thrust of the lifting component is increased, allowing the water flow to rinse the filter screen at a faster speed, thoroughly rinsing the filter screen.

[0008] Preferably, the lifting assembly includes a water inlet pipe fixedly connected to the inner wall of the spring sleeve; The spraying assembly includes a nozzle that is connected through to the outer wall of the water inlet pipe, and an arc-shaped stop is slidably connected to the inner wall of the nozzle; The operator connects the sleeve to an external water pipe, which in turn connects to an external water pump, keeping the sleeve vertically upward. When the lawn needs irrigation, the pump is activated to deliver water into the sleeve. As the water flows through the filter screen, it filters out impurities. The water then contacts the bottom of the spring sleeve. Due to the pressure from the pump, the spring sleeve is lifted, accumulating rebound force. The spring sleeve also causes the inlet pipe and nozzle to rise.

[0009] Preferably, the collection assembly includes a beveled collection ring fixedly connected to the inner wall of the sleeve, and a sealing rod fixedly connected to the inner wall of the sleeve; As the spring sleeve continues to move, it will stop moving when it is blocked by the protrusion inside the sleeve. The nozzle will then extend out of the sleeve, and the water inlet pipe will separate from the sealing rod. Water will then enter the water inlet pipe and flow into the nozzle, spraying water onto the lawn to irrigate it.

[0010] Preferably, the pushing component includes a drain pipe that is connected through the inner wall of the inclined collecting ring, the outer wall of the drain pipe being connected through the inner wall of the sleeve, a U-shaped rod being fixedly connected to the bottom of the spring ring, the top of the U-shaped rod being fixedly connected to the bottom of the blocking rod, and a sealing ring II being fixedly connected to both the outer wall and the inner wall of the spring ring to prevent water from entering the top of the spring ring. When the water flow pushes the spring sleeve upward, it also pushes the spring ring upward, allowing the spring ring to accumulate rebound force. When the spring ring rises, it will drive the U-shaped rod and the blocking rod to rise. When the notch of the blocking rod is aligned with the drain pipe, it will connect with the outside, allowing some water to flow out of the drain pipe. As the spring ring continues to move, the notch of the blocking rod will separate from the drain pipe, blocking the drain pipe again and preventing the water flow. When irrigation is complete, the water pump stops. At this time, the thrust of the water flow disappears, and the rebound force of the spring sleeve is released, which drives the inlet pipe and the nozzle back to their original positions. The water is squeezed into the inlet pipe and discharged through the inlet pipe until the blocking rod re-enters the inlet pipe, occupying the space of the inlet pipe. The water will then be discharged through the gap between the two, reducing the amount of water discharged. At the same time, the rebound force of the spring ring is also released, causing the spring ring to return to its original position, which drives the U-shaped rod and the blocking rod back to their original positions. When the notch of the blocking rod is aligned with the drain pipe again, the spring sleeve will squeeze the water through the filter screen and into the inclined collection ring, and then discharge it through the drain pipe. Additionally: During backwashing of the filter screen, as water flows out through the drain pipe, the impurities washed out will also move with the water flow towards the left side of the inclined collection ring and enter the inclined collection ring. Some impurities will be discharged with the water flow. After the spring sleeve and spring ring return to their original positions, the water flow will remain stable, and the remaining impurities will settle at the bottom of the inclined collection ring along the inclined surface. When the lawn is irrigated again, the water flow will squeeze the spring ring upwards, causing the U-shaped rod and the blocking rod to rise. When the notch of the blocking rod aligns with the drain pipe again, the water flow will enter from the left side of the inclined collection ring. Since the left side of the inclined collection ring is higher and the right side is lower, it facilitates the flow of impurities. Impurities entering the bottom of the inclined collection ring will be blocked by the outer wall of the inclined collection ring, reducing the escape of impurities. The water flow will then push the impurities towards the drain pipe on the right side, discharging them and reducing the residue of impurities. This effectively prevents impurities washed out of the filter screen from accumulating inside the sleeve. When irrigating again, the water flow will push the impurities to re-attach to the surface of the filter screen.

[0011] Preferably, the striking assembly includes a spring return rod fixedly connected to the inner wall of the fixed ring, and a sliding frame is provided on the inner wall of the fixed ring, with the inner wall of the sliding frame slidably connected to the outer wall of the spring return rod.

[0012] Preferably, the striking assembly further includes a protruding plate fixedly connected to the bottom of the spring ring, and a connecting rod rotatably connected to the top of the sliding frame, with the inner wall of the connecting rod rotatably connected to the side wall of the sliding ring. When the spring ring rises, it drives the convex plate to move. The protruding part of the convex plate will contact the sliding frame. Since the contact surfaces of both are arc surfaces, the convex plate will squeeze the sliding frame towards the fixed ring, causing the sliding frame to squeeze the spring return rod. This allows the spring return rod to accumulate rebound force, which in turn pushes the connecting rod to rotate. The connecting rod then pushes the sliding ring to rise, causing the spring rod to rise and contact the bottom of the inclined collecting ring. As the sliding ring continues to move, it will squeeze the spring of the spring rod, allowing it to accumulate rebound force until the protruding part of the convex plate separates from the sliding ring.

[0013] Preferably, the compression assembly includes a piston cylinder fixedly connected to the inner wall of the sleeve, a piston ring slidably connected to the inner wall of the piston cylinder, and sealing rings fixedly connected to both the outer and inner walls of the piston ring to ensure that gas is difficult to leak to the bottom of the piston ring when the gas is compressed. As the spring sleeve rises, it contacts the piston ring, lifting it and causing it to compress the gas inside the piston cylinder, generating high pressure. When the water flow's thrust disappears, the pressure on the spring sleeve and piston ring also disappears. The pressure accumulated in the high-pressure gas inside the piston ring, along with the rebound force accumulated in the spring sleeve, are released simultaneously. The combined rebound force accelerates the initial return speed of the spring sleeve, increasing the water flow rate and generating a stronger impact force. This washes away impurities in the filter screen, resulting in more thorough separation of impurities.

[0014] The present invention has the following beneficial effects: (1) When using this invention, the operator connects the sleeve to the external water pipe, which is connected to the external water pump. The water pump is started to deliver water into the sleeve. Through the lifting component and the spraying component, the nozzle sprays water to irrigate the lawn. The water flow also pushes the spring ring to rise, which in turn drives the blocking rod to rise. When irrigation is completed, the water pump is stopped, and the spring sleeve's rebound force is released, which drives the water inlet pipe and the nozzle back to their original positions. At the same time, the spring ring's rebound force is also released, aligning the notch of the blocking rod with the drain pipe. Since the water flow between the top of the filter screen and the bottom of the spring sleeve is relatively clean after filtration, the spring sleeve will squeeze the clean water to rinse the filter screen. The water flow is discharged through the drain pipe, separating impurities from the filter screen. By rinsing the filter screen with clean water after each irrigation, impurities are effectively prevented from adhering to the filter screen's pores, causing the filter screen to become clogged, resulting in a decrease in water flow, a shorter spray distance from the nozzle, and a smaller irrigation range. This ensures that the irrigation range is complete and the lawn is watered evenly.

[0015] (2) When the filter screen is backwashed, the water will be discharged through the drain pipe and the impurities washed out will also follow the flow of the water. Some impurities will be discharged with the water flow. After the spring sleeve and spring ring return to their original positions, the remaining impurities will settle down along the slope to the bottom of the slope collection ring. When the lawn is irrigated again, the water will squeeze the spring ring to rise again, driving the U-shaped rod and the blocking rod to rise. When the notch of the blocking rod is aligned with the drain pipe again, the water will push the impurities to move towards the drain pipe on the right side and discharge the impurities, thereby reducing the residue of impurities and effectively preventing the impurities washed out of the filter screen from accumulating in the sleeve. When irrigated again, the water will push the impurities to adhere to the surface of the filter screen again. (3) When the spring ring rises, it will drive the convex plate to move. The convex plate will then squeeze the sliding frame to move towards the fixed ring. By striking the component, it will drive the spring rod to rise, so that the spring rod contacts the bottom of the inclined collecting ring until the protruding part of the convex plate separates from the sliding ring. At this time, the rebound force of the spring rod is released, so that multiple spring rods strike the bottom of the inclined collecting ring multiple times, causing the bottom of the inclined collecting ring to vibrate. This suspends the impurities at the bottom of the inclined collecting ring, making it easier for the water flow to carry the impurities out. This effectively prevents the impurities from settling at the bottom of the inclined collecting ring. Some solid impurities will adhere to the bottom of the inclined collecting ring, and the water flow may have difficulty discharging the attached impurities, thereby reducing the deposition of impurities.

[0016] (4) When the spring sleeve rises, as the spring sleeve continues to move, the spring sleeve will come into contact with the piston ring, which will lift the piston ring and cause the piston ring to squeeze the gas in the piston cylinder, so that the gas generates high pressure. When the thrust of the water flow disappears, the squeezing force on the spring sleeve and the piston ring disappears. The pressure accumulated by the high pressure gas in the piston ring and the rebound force accumulated by the spring sleeve will be released simultaneously. The two rebound forces add up to accelerate the initial return speed of the spring sleeve, so that when the spring sleeve squeezes the water flow, it will accelerate the flow rate of the water flow and generate a stronger impact force, washing away the impurities in the filter screen and making the impurities in the filter screen more thoroughly separated.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1, please refer to Figures 1-4 The present invention is an agricultural and garden irrigation device, including a sleeve 111, a spring sleeve 112 slidably connected to the inner wall of the sleeve 111, a filter screen 212 fixedly connected to the inner wall of the sleeve 111, and a sealing ring 1 fixedly connected to the outer wall of the spring sleeve 112 to prevent water from entering the top of the spring sleeve 112. An irrigation mechanism 1 is provided with a lifting component 11 slidably disposed on the inner wall of the irrigation mechanism 1, and a spraying component 12 is installed on the top of the irrigation mechanism 1. The lifting component 11 is used to lift the spraying component 12. Sewage discharge mechanism 2, installed on the inner wall of irrigation mechanism 1, is used to flush out impurities from filter screen 212; and Separation mechanism 3, located on the inner wall of irrigation mechanism 1, is used to keep impurities in a suspended state; A fixing ring 221 is fixedly connected to the inner wall of the sleeve 111, a spring ring 222 is slidably connected to the inner wall of the fixing ring 221, and a blocking rod 225 is slidably connected to the inner wall of the sleeve 111. The sleeve 111 is connected to a water pipe. An external water pump pumps water into the sleeve 111, which pushes the irrigation mechanism 1 to rise and irrigate the lawn. When the water pump stops, the sewage discharge mechanism 2 backwashes the filter screen 212 to clean it and effectively prevent impurities from adhering to the filter holes of the filter screen 212, causing the filter screen 212 to become clogged, resulting in a decrease in water flow and a smaller irrigation range. Finally, the impurities are discharged through the separation mechanism 3.

[0022] Irrigation facility 1 includes: The lifting component 11 is slidably disposed on the outer wall of the lifting component 111 and the inner wall of the sleeve 111, and is used to lift the spraying component 12. The bottom of the spraying assembly 12 is fixedly installed with the top of the spring sleeve 112, and is used to spray water to irrigate the lawn. The operator connects the sleeve 111 to the water pipe and pumps water into the sleeve 111 through an external water pump. The water is filtered through the filter screen 212 and then the water flow lifts the spraying component 12 to irrigate the lawn.

[0023] Sewage discharge facility 2 includes: Collection component 21 is fixedly installed on the inner wall of sleeve 111 and is used to collect impurities flushed out of filter screen 212; Push component 22 is fixedly installed on the inner wall of sleeve 111 to discharge the collected impurities; When irrigation is complete and the water pump is stopped, the lifting component 11 will return to its original position, squeezing the filtered water flow and backwashing the impurities in the filter screen 212 to prevent impurities from adhering to the filter screen 212 and causing blockage, which would lead to a decrease in water flow and a shorter spray distance from the nozzle 121. When irrigation is carried out again, the water flow will push the pushing component 22 to rise, and the pushing component 22 will discharge the collected impurities, effectively preventing the impurities washed out of the filter screen 212 from accumulating in the sleeve 111. When irrigation is carried out again, the water flow will push the impurities to adhere to the surface of the filter screen 212 again.

[0024] Separation mechanism 3 includes: The striking component 31 is slidably disposed on the inner wall of the sleeve 111 via a slider, and is used to keep the impurities in the collection component 21 in a suspended state. The sliding component includes a sliding ring 311 that is slidably connected to the inner wall of the sleeve 111, and eleven spring rods 316 are slidably connected to the inner wall of the sliding ring 311. Compression component 32 is fixedly installed on the inner wall of sleeve 111 to increase the thrust of lifting component 11; When the push component 22 is raised, it will drive the striking component 31 to rise, repeatedly striking the bottom of the collecting component 21, so that the impurities collected by the collecting component 21 are in a suspended state, effectively preventing the impurities from settling at the bottom of the inclined collecting ring 211. Some solid impurities will adhere to the bottom of the inclined collecting ring 211, and the water flow may have difficulty discharging the attached impurities, thereby reducing the deposition of impurities. At the same time, by compressing the component 32, the back thrust of the lifting component 11 is increased, so that the water flow can rinse the filter screen 212 at a faster speed, thoroughly rinsing the filter screen 212.

[0025] Example 2, please refer to Figures 1-9 The present invention is an agricultural and garden irrigation device. Based on Example 1, the lifting component 11 includes a water inlet pipe 113 fixedly connected to the inner wall of the spring sleeve 112. The spraying assembly 12 includes a nozzle 121 that is connected through to the outer wall of the water inlet pipe 113, and an arc-shaped stop 122 that is slidably connected to the inner wall of the nozzle 121. The operator connects the sleeve 111 to an external water pipe, which in turn connects to an external water pump, so that the sleeve 111 is vertically upward. When the lawn needs irrigation, the water pump is started to deliver water into the sleeve 111. When the water flows through the filter screen 212, the filter screen 212 filters out impurities in the water flow. Then, the water flow contacts the bottom of the spring sleeve 112. Because the water flow is pressurized by the water pump, it will push the spring sleeve 112 up, allowing the spring sleeve 112 to accumulate rebound force. The spring sleeve 112 will also drive the water inlet pipe 113 and the nozzle 121 to rise.

[0026] The collection assembly 21 includes an inclined collection ring 211 fixedly connected to the inner wall of the sleeve 111, and a sealing rod 213 fixedly connected to the inner wall of the sleeve 111. As the spring sleeve 112 continues to move, until it is blocked by the protruding part inside the sleeve 111, as... Figure 4 As shown in position G, the spring sleeve 112 will stop moving, the nozzle 121 will extend out of the sleeve 111, and the water inlet pipe 113 will also separate from the sealing rod 213. Water will enter the water inlet pipe 113 and then enter the nozzle 121 through the water inlet pipe 113, spraying water onto the lawn to irrigate it.

[0027] The pushing component 22 includes a drain pipe 223 that is connected through the inner wall of the inclined collection ring 211. The outer wall of the drain pipe 223 is connected through the inner wall of the sleeve 111. A U-shaped rod 224 is fixedly connected to the bottom of the spring ring 222. The top of the U-shaped rod 224 is fixedly connected to the bottom of the blocking rod 225. Sealing rings 222 are fixedly connected to both the outer and inner walls of the spring ring 222 to prevent water from entering the top of the spring ring 222. When the water flow pushes the spring sleeve 112 upward, it also pushes the spring ring 222 upward, allowing the spring ring 222 to accumulate rebound force. As the spring ring 222 rises, it drives the U-shaped rod 224 and the blocking rod 225 upward. When the notch of the blocking rod 225 aligns with the drain pipe 223, as... Figure 6 As shown in the position of H, it will connect with the outside, allowing some water to be discharged from the drain pipe 223. As the spring ring 222 continues to move, the notch of the blocking rod 225 will separate from the drain pipe 223, blocking the drain pipe 223 again and preventing the water flow. When irrigation is complete, the water pump stops. At this time, the thrust of the water flow disappears, and the rebound force of the spring sleeve 112 is released, which drives the water inlet pipe 113 and the nozzle 121 back to their original positions. The water flow is squeezed into the water inlet pipe 113 and discharged through the water inlet pipe 113 until the blocking rod 213 re-enters the water inlet pipe 113 and occupies the space of the water inlet pipe 113. The water flow will then be discharged through the gap between the two, reducing the water flow. At the same time, the rebound force of the spring ring 222 is also released, causing the spring ring 222 to return to its original position, which drives the U-shaped rod 224 and the blocking rod 225 back to their original positions. When the notch of the blocking rod 225 is aligned with the drain pipe 223 again, the spring sleeve 112 will squeeze the water flow through the filter screen 212 and into the inclined collection ring 211, and then discharge it through the drain pipe 223. Additionally: During backwashing of filter screen 212, as water flows out through drain pipe 223, the washed-out impurities will also move with the water flow towards the left side of inclined collection ring 211 and enter the inclined collection ring 211. Some impurities will be discharged with the water flow. After spring sleeve 112 and spring ring 222 return to their original positions, the water flow will remain stable, and the remaining impurities will settle at the bottom of inclined collection ring 211 along its slope. Figure 9 The position of I in the middle is shown; When the lawn is irrigated again, the water flow will squeeze the spring ring 222 upward again, causing the U-shaped rod 224 and the blocking rod 225 to rise. When the notch of the blocking rod 225 is aligned with the drain pipe 223 again, the water flow will enter from the left side of the inclined collection ring 211. Since the left side of the inclined collection ring 211 is higher and the right side is lower, it facilitates the flow of impurities. Impurities entering the bottom of the inclined collection ring 211 will be blocked by the outer wall of the inclined collection ring 211, reducing the escape of impurities. The water flow will push the impurities towards the drain pipe 223 on the right side and discharge the impurities, thereby reducing the residue of impurities and effectively preventing the impurities washed out of the filter screen 212 from accumulating in the sleeve 111. When irrigating again, the water flow will push the impurities to re-attach to the surface of the filter screen 212.

[0028] The striking assembly 31 includes a spring return rod 314 fixedly connected to the inner wall of the fixed ring 221. A sliding frame 313 is provided on the inner wall of the fixed ring 221, and the inner wall of the sliding frame 313 is slidably connected to the outer wall of the spring return rod 314.

[0029] The striking assembly 31 also includes a protruding plate 312 fixedly connected to the bottom of the spring ring 222, and a connecting rod 315 rotatably connected to the top of the sliding frame 313, with the inner wall of the connecting rod 315 rotatably connected to the side wall of the sliding ring 311. When the spring ring 222 rises, it drives the convex plate 312 to move. The protruding part of the convex plate 312 will contact the sliding frame 313. Since the contact surfaces of both are arc surfaces, the convex plate 312 will squeeze the sliding frame 313 to move towards the fixed ring 221, so that the sliding frame 313 squeezes the spring return rod 314, allowing the spring return rod 314 to accumulate rebound force. The sliding frame 313 will push the connecting rod 315 to rotate, so that the connecting rod 315 pushes the sliding ring 311 to rise, driving the spring rod 316 to rise, so that the spring rod 316 contacts the bottom of the inclined collecting ring 211. The sliding ring 311 continues to move, which will squeeze the spring of the spring rod 316, allowing it to accumulate rebound force until the protruding part of the convex plate 312 separates from the sliding ring 311.

[0030] The compression assembly 32 includes a piston cylinder 321 fixedly connected to the inner wall of the sleeve 111. A piston ring 322 is slidably connected to the inner wall of the piston cylinder 321. Sealing rings are fixedly connected to both the outer and inner walls of the piston ring 322 to ensure that gas is difficult to leak to the bottom of the piston ring 322 when the gas is compressed. As the spring sleeve 112 rises, it contacts the piston ring 322 as it continues to move, lifting the piston ring 322 and causing it to compress the gas inside the piston cylinder 321, generating high pressure. When the water flow's thrust disappears, the compressive force on the spring sleeve 112 and piston ring 322 also disappears. The pressure accumulated in the high-pressure gas inside the piston ring 322, along with the rebound force accumulated in the spring sleeve 112, are released simultaneously. The combined rebound force accelerates the initial return speed of the spring sleeve 112, increasing the water flow rate and generating a stronger impact force. This washes away impurities in the filter screen 212, resulting in more thorough separation of impurities.

[0031] The number of the above components is not limited. Those skilled in the art can set it freely according to actual needs, as long as the above components are installed at the corresponding component connection positions.

[0032] A specific application of this embodiment is as follows: When using this invention, the operator connects the sleeve 111 to an external water pipe, which in turn connects to an external water pump, making the sleeve 111 vertically upward. When irrigation of the lawn is needed, the water pump is activated to deliver water into the sleeve 111. As the water flows through the filter screen 212, the filter screen 212 filters out impurities in the water. Then, the water flows into contact with the bottom of the spring sleeve 112. Due to the pressure exerted by the water pump, the spring sleeve 112 is lifted, accumulating a rebound force. The spring sleeve 112 also drives the inlet pipe 113 and the nozzle 121 to rise until the spring sleeve 112 is blocked by a protruding part inside the sleeve 111. Figure 4As shown in position G, the spring sleeve 112 will stop moving, the nozzle 121 will extend out of the sleeve 111, the water inlet pipe 113 will also separate from the sealing rod 213, the water will enter the water inlet pipe 113, and then enter the nozzle 121 through the water inlet pipe 113 to spray water onto the lawn and irrigate the lawn. As the water flow pushes the spring sleeve 112 upward, it also pushes the spring ring 222 upward, allowing the spring ring 222 to accumulate rebound force. As the spring ring 222 rises, it drives the U-shaped rod 224 and the blocking rod 225 upward. When the notch of the blocking rod 225 aligns with the drain pipe 223, ... Figure 6 As shown in the position of H, it will connect with the outside, allowing some water to be discharged from the drain pipe 223. As the spring ring 222 continues to move, the notch of the blocking rod 225 will separate from the drain pipe 223, blocking the drain pipe 223 again and preventing the water flow. When irrigation is complete, the water pump stops. At this time, the thrust of the water flow disappears, and the rebound force of the spring sleeve 112 is released, which drives the water inlet pipe 113 and the nozzle 121 back to their original positions. The water flow is squeezed into the water inlet pipe 113 and discharged through the water inlet pipe 113 until the blocking rod 213 re-enters the water inlet pipe 113 and occupies the space of the water inlet pipe 113. The water flow will then be discharged through the gap between the two, reducing the water flow. At the same time, the rebound force of the spring ring 222 is also released, causing the spring ring 222 to return to its original position, which drives the U-shaped rod 224 and the blocking rod 225 back to their original positions. When the notch of the blocking rod 225 is aligned with the drain pipe 223 again, the spring sleeve 112 will squeeze the water flow through the filter screen 212 and into the inclined collection ring 211, and then discharge it through the drain pipe 223. Because the water flow between the top of the filter screen 212 and the bottom of the spring sleeve 112 is relatively clean after filtration, when the clean water flow squeezed by the spring sleeve 112 passes through the filter screen 212, it will backwash the impurities in the filter screen 212, causing the impurities to separate from the filter screen 212 and fall into the inclined collection ring 211. By rinsing the filter screen 212 with clean water after each irrigation, it is possible to effectively prevent impurities from adhering to the filter holes of the filter screen 212 and gradually accumulating, causing the filter screen 212 to become clogged, resulting in a decrease in water flow, a shorter water flow distance from the nozzle 121, and a smaller irrigation range, thereby ensuring the integrity of the irrigation range and uniform water supply to the lawn. Secondly, during backwashing of filter screen 212, as water flows out through drain pipe 223, the washed-out impurities also move with the water flow towards the left side of inclined collection ring 211 and enter the inclined collection ring 211. Some impurities are discharged with the water flow. After spring sleeve 112 and spring ring 222 return to their original positions, the water flow will remain stable, and the remaining impurities will settle at the bottom of inclined collection ring 211 along the slope. Figure 9 The position of I in the middle is shown; When the lawn is irrigated again, the water flow will squeeze the spring ring 222 upward again, causing the U-shaped rod 224 and the blocking rod 225 to rise. When the notch of the blocking rod 225 is aligned with the drain pipe 223 again, the water flow will enter from the left side of the inclined collection ring 211. Since the left side of the inclined collection ring 211 is higher and the right side is lower, it is convenient for impurities to flow. The impurities entering the bottom of the inclined collection ring 211 will be blocked by the outer wall of the inclined collection ring 211, reducing the escape of impurities. The water flow will push the impurities towards the drain pipe 223 on the right side to discharge the impurities, thereby reducing the residue of impurities and effectively preventing the impurities washed out of the filter screen 212 from accumulating in the sleeve 111. When irrigating again, the water flow will push the impurities to adhere to the surface of the filter screen 212 again. Secondly, when the spring ring 222 rises, it will drive the convex plate 312 to move. The protruding part of the convex plate 312 will contact the sliding frame 313. Since the contact surfaces of both are arc surfaces, the convex plate 312 will squeeze the sliding frame 313 to move towards the fixed ring 221, so that the sliding frame 313 squeezes the spring return rod 314, allowing the spring return rod 314 to accumulate rebound force. The sliding frame 313 will push the connecting rod 315 to rotate, so that the connecting rod 315 pushes the sliding ring 311 to rise, driving the spring rod 316 to rise, so that the spring rod 316 contacts the bottom of the inclined collecting ring 211. The sliding ring 311 continues to move, which will squeeze the spring of the spring rod 316, allowing it to accumulate rebound force until the protruding part of the convex plate 312 separates from the sliding ring 311. At this time, the spring return rod 314 will release its elastic force, allowing the sliding frame 313 and the sliding ring 311 to return to their original positions. This will release the elastic force of the spring rod 316, causing it to vibrate and contact the bottom of the inclined collecting ring 211, striking the bottom of the inclined collecting ring 211 until the protruding position of the convex plate 312 is reached. Then, the sliding frame 313 will be squeezed again. This process is repeated, allowing multiple spring rods 316 to strike the bottom of the inclined collecting ring 211 multiple times, causing the bottom of the inclined collecting ring 211 to vibrate. This suspends the impurities at the bottom of the inclined collecting ring 211, making it easier for the water flow to carry the impurities out. This effectively prevents impurities from settling at the bottom of the inclined collecting ring 211. Some solid impurities may adhere to the bottom of the inclined collecting ring 211, making it difficult for the water flow to remove the attached impurities, thus reducing the deposition of impurities. Secondly, as the spring sleeve 112 rises, it continues to move and comes into contact with the piston ring 322, which in turn lifts the piston ring 322, causing it to compress the gas inside the piston cylinder 321 and generate high pressure. When the thrust of the water flow disappears, the compressive force on the spring sleeve 112 and the piston ring 322 also disappears. The pressure accumulated by the high-pressure gas inside the piston ring 322 and the rebound force accumulated by the spring sleeve 112 are released simultaneously. The addition of these two rebound forces will accelerate the initial return speed of the spring sleeve 112, thus increasing the flow rate of the water when the spring sleeve 112 compresses it, resulting in a stronger impact force that washes away impurities in the filter screen 212, making the separation of impurities in the filter screen 212 more thorough.
