Description

Technical Field

[0001] This invention relates to the field of irrigation equipment technology, specifically to a timed drip irrigation device for Forsythia seedling cultivation. Background Technology

[0002] Forsythia is a shrub with both medicinal and ecological value, and it is widely planted in many parts of my country. Its seedling stage is quite sensitive to environmental conditions, especially water management. The forsythia seedling device with timed drip irrigation is an agricultural equipment that combines drip irrigation technology with intelligent control functions. By adjusting the amount and time of irrigation, it ensures that the soil moisture meets the requirements for seedling cultivation.

[0003] Current drip irrigation systems work by drilling multiple holes in branch pipes, installing drip heads in the holes, with each drip head corresponding to a single Forsythia seedling for irrigation. A main control switch then controls the water supply to the main pipe at specific times, and the spacing between the holes corresponds to the distance between each Forsythia seedling. To address the issues of localized soil over-wetting and depressions caused by long-term fixed-point dripping during drip irrigation, as well as uneven irrigation coverage, the commonly used improvement method is to reduce the spacing between the water outlets on the extension pipe and to lay the pipe around the Forsythia seedlings to expand the drip irrigation coverage. However, this method requires densely perforated pipes, which affects the strength of the pipes. During daily water supply, there is a certain water pressure inside the pipes. The pipes with reduced strength cannot withstand the continuous water pressure and are prone to cracking, deformation, and other problems, which in turn cause water leakage. Moreover, some seedlings in the leaking area will also be affected, disrupting the normal water balance required for seedling growth. Summary of the Invention

[0004] The purpose of this invention is to provide a timed drip irrigation device for Forsythia seedling cultivation, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides a timed drip irrigation device for Forsythia seedlings, comprising a water delivery pipe body and a plurality of drip irrigation heads fixed at equal intervals on the water delivery pipe body. Each drip irrigation head includes an outer shell with a vertically arranged channel inside, its upper end connected to the water delivery pipe body, and its lower end having a water outlet. It also includes... A rotating plate is rotatably mounted at the bottom of the outer casing. A protrusion is provided at the eccentric part of the bottom of the rotating plate. A transmission rod is provided at the center of the upper end of the rotating plate. The upper end of the transmission rod extends vertically from the channel of the outer casing into the water supply pipe body. An impeller is connected to the extended end of the transmission rod. A diversion plate is disposed on the main body or outer shell of the water supply pipe and located below the rotating plate. The diversion plate is elastic and includes at least a plurality of arched surfaces arranged in a circular array with the center of the rotating plate as the center. The arched surfaces bend and protrude in the direction of the outer shell, so that a concave surface is formed between two adjacent arched surfaces. The concave surface extends horizontally outward or gradually tilts upward along the radial direction of the diversion plate. When the rotating plate rotates with the impeller, the protrusions successively squeeze the arched surfaces, causing the corresponding concave surfaces to tilt downward and deform.

[0006] Furthermore, the middle area of ​​the rotating plate near the transmission rod is close to the bottom end of the outer shell, the outer ring wall of the rotating plate is vertically inclined in the direction opposite to the outer shell, and a first slide rail extending from the middle of the rotating plate to the outer ring wall is opened at the bottom of the rotating plate, and the protrusion is slidably connected to the first slide rail.

[0007] Furthermore, the water supply pipe body is also connected to an outer cylinder, which extends into the channel and coincides with the axis of the channel. A baffle is vertically slidably connected to the outer wall of the outer cylinder. The baffle is hollow and has buoyancy. The outer ring wall of the baffle is close to the inner wall of the outer shell. A cavity is opened in the outer cylinder, and a strip-shaped opening communicating with the cavity is opened through the outer cylinder. The cavity is equipped with a pull rope. One end of the pull rope extends into the first slide and is connected to the protrusion, while the other end is connected to the inner ring wall of the baffle. When the baffle moves vertically with changes in water pressure, the pull rope pulls the protrusion to slide back and forth along the first slide.

[0008] Furthermore, the main body of the water supply pipe has an opening communicating with the channel. A water leakage plate is installed on the inner wall of the opening. The water leakage plate is connected to the outer wall of the outer cylinder. The transmission rod is located in the cavity. The circumference of the transmission rod is smaller than the circumference of the inner wall of the cavity. The pull rope is located between the transmission rod and the cavity. A fixing rod is also provided inside the transmission rod. The top end of the fixing rod is connected to the inner wall of the main body of the water supply pipe. The bottom end of the fixing rod is connected to the middle of the top of the diversion plate. The transmission rod and the impeller are rotatably connected to the outer wall of the fixing rod.

[0009] Furthermore, a fixing plate is installed on the inner ring wall of the rotating plate, and the fixing plate has multiple first water passage holes through it. The inner ring wall of the fixing plate is connected to the outer wall of the transmission rod.

[0010] Furthermore, the outer cylinder has multiple second water passage holes that communicate with the cavity. The multiple second water passage holes are arranged vertically at equal intervals along the direction of the outer cylinder. A support ring is vertically slidably connected to the inner wall of the cavity. The top and bottom of the support ring are provided with annular through grooves. An annular embedding groove is provided inside the support ring. A sliding block is slidably connected inside the annular embedding groove. The end of the pull rope away from the protrusion is connected to the bottom of the sliding block. The inner ring wall of the baffle is provided with an annular embedded sliding groove, and a connecting rod is slidably connected in the annular embedded sliding groove. The end of the connecting rod away from the annular embedded sliding groove passes through the strip opening and is connected to the outer wall of the support ring.

[0011] Furthermore, the protrusion includes a push block, and second slides are provided on the inner walls of both sides of the first slide. A slide rod is slidably connected between the two second slides. The push block is connected to the outer wall of the slide rod, and one end of the pull rope extends into the first slide and is connected to the outer wall of the slide rod.

[0012] Furthermore, the drainage plate also includes a core, which is located at the center of the drainage plate. The inner wall of the concave surface is provided with multiple diversion channels, one end of which extends to the outer edge of the concave surface and the other end extends to the edge of the core.

[0013] Furthermore, a connecting ring is installed on the outer edge of the rotating plate, and an annular slider is installed on the inner ring wall of the connecting ring. A slide rail is installed on the outer wall of the outer shell, and the annular slider is slidably connected to the slide rail. An annular groove is opened on the outer wall of the outer cylinder, and the annular groove is close to the bottom end of the outer cylinder. A collar is installed on the inner ring wall of the rotating plate, and an embedded ring extending into the annular groove is installed on the inner ring wall of the collar. The embedded ring is slidably connected to the annular groove. There is a gap between the bottom end of the collar and the top of the fixed plate. One end of the first slide is located at the gap, and the pull rope extends into the first slide through the gap.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the water flow circulating in the water delivery pipe drives the impeller and the transmission rod to rotate the rotating plate and the protrusion, so that the protrusion successively squeezes the arched surface on the diversion plate, causing the adjacent concave surfaces to tilt alternately, so that the edge of the diversion plate drips water onto the Forsythia seedlings alternately. At the same time, the shaking generated by the rebound of the arched surface can disperse the water flow and change the drip position, further ensuring the uniformity of irrigation.

[0015] 2. In this invention, when the protrusion slides along the first slide and slides towards the outer edge of the rotating plate, the rotating plate gradually tilts downward from the center to the outer edge. The closer the protrusion is to the outer edge, the closer it is to the guide plate. The closer it is to the guide plate, the greater the downward tilt angle is caused by the compression of the arched surface. The water pressure increases and the flow rate increases, and the water flows out quickly. After the protrusion leaves, the rebound angle of the two increases and the shaking is longer, and the water is more dispersed and the range is larger. Attached Figure Description

[0018] 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.

[0019] This invention provides a technical solution: See Figures 1-18 As shown, a timed drip irrigation device for Forsythia seedlings includes a water supply pipe body 1 and multiple drip irrigation heads fixed at equal intervals on the water supply pipe body 1. Each drip irrigation head includes an outer shell 2 with a vertically arranged channel inside, its upper end connected to the water supply pipe body 1, and its lower end having a water outlet. It also includes... A rotating plate 13 is rotatably mounted at the bottom of the outer casing 2. A protrusion is provided at the eccentric part of the bottom of the rotating plate 13. A transmission rod 12 is provided at the center of the upper end of the rotating plate 13. The upper end of the transmission rod 12 extends vertically from the channel of the outer casing 2 into the water supply pipe body 1. An impeller 3 is connected to the extended end of the transmission rod 12. The diversion plate 7 is disposed on the main body 1 or the outer shell 2 of the water supply pipe and located below the rotating plate 13. The diversion plate 7 is elastic and includes at least a plurality of arched surfaces 702 arranged in a circular array with the center of the rotating plate 13 as the center. The arched surfaces 702 bend and protrude towards the outer shell 2, so that an inner concave surface 703 is formed between two adjacent arched surfaces 702. The inner concave surface 703 extends horizontally outward or gradually tilts upward along the radial direction of the diversion plate 7. When the rotating plate 13 rotates with the impeller 3, the protrusions successively squeeze the arched surfaces 702, causing the corresponding inner concave surfaces 703 to tilt downward and deform.

[0020] The top of the outer shell 2 is fixedly connected to the outer wall of the water supply pipe body 1. The channel inside the outer shell 2 is connected to the inside of the water supply pipe body 1. There is a gap between the guide plate 7 and the bottom of the outer shell 2. The water in the water supply pipe body 1 circulates. During the water circulation, the impeller 3 is driven to rotate. The impeller 3 rotates and drives the transmission rod 12 to rotate. The transmission rod 12 drives the rotating plate 13 to rotate together. When the rotating plate 13 rotates, it drives the protrusion to rotate around the transmission rod 12. The protrusion rotates around the circumference and squeezes the upward protruding arched surface 702 in sequence. Can be combined Figure 11 As you can see, water droplets inside the outer shell 2 fall into the central area of ​​the top of the drainage plate 7. The arched surface 702 and the concave surface 703 are located at the inner end of the drainage plate 7 and the outer end of the drainage plate 7 at the outer edge. When water droplets fall on the drainage plate 7, the rotating plate 13 causes the protrusion to press against the arched surface 702. The outer arc surface of the arched surface 702 is squeezed and deforms downward, which in turn causes the outer ends of the two adjacent concave surfaces 703 to tilt downward. Then, the water concentrated in the central area of ​​the drainage plate 7 will flow into the corresponding tilted concave surface 703 and fall down along the concave surface 703. Multiple concave surfaces 703 and arched surfaces 702 are arranged around the drainage plate 7. When the protrusion rotates, it squeezes the arched surfaces 702 one by one, causing the multiple concave surfaces 703 to tilt downward alternately. Then the outer edge of the entire drainage plate 7 will drip water downward alternately. Multiple forsythia seedlings are placed below the drainage plate 7 and correspond to the outer edge of the drainage plate 7. Then the drainage plate 7 drips water around the forsythia seedlings alternately. After the protrusion presses against the arched surface 702 and rotates to be above the concave surface 703, the protrusion will not contact the concave surface 703. Then, the elastic arched surface 702 will bounce upward. During the bounce, the arched surface 702 will shake in the up and down direction with the concave surface 703. First, the shaking can spread the water. Second, after each shaking, the water will not fall in a fixed position. This can avoid repeated drip irrigation of the same position to prevent the local soil from becoming too wet.

[0021] See Figures 4-5 The middle area of ​​the rotating plate 13 near the transmission rod 12 is close to the bottom of the outer shell 2. The outer ring wall of the rotating plate 13 is vertically inclined in the direction opposite to the outer shell 2. The bottom of the rotating plate 13 has a first slide 15 extending from its middle to the outer ring wall. The protrusion is slidably connected to the first slide 15.

[0022] The rotating plate 13 is located at the bottom of the outer shell 2. A through opening is provided in the center of the rotating plate 13, which serves as the inner ring wall of the rotating plate 13. The top of the inner ring wall of the rotating plate 13 is close to the bottom of the outer shell 2, while the outer ring wall of the rotating plate 13 is inclined downward. Therefore, there is a distance between the top of the outer ring wall of the rotating plate 13 and the bottom of the outer shell 2. The protrusion can slide along the first slide 15. As the protrusion slides along the first slide 15 toward the outer edge of the rotating plate 13, the rotating plate 13 gradually tilts downward from the center to the outer edge. Therefore, the closer the protrusion is to the outer edge of the rotating plate 13, the closer the protrusion is to the drainage plate 7. As the protrusion gets closer to the guide plate 7, the angle at which the protrusion presses against the arched surface 702 and tilts downwards increases when the rotating plate 13 drives the protrusion to rotate. Due to the increased water pressure, the water flow also increases, and the angle at which the outer ends of the arched surface 702 and the concave surface 703 tilt downwards increases, allowing the water to flow out quickly. At the same time, after the protrusion leaves the tilted arched surface 702, the angle at which the arched surface 702 and the concave surface 703 rebound upwards also increases, resulting in a longer shaking time, which makes the water more dispersed and the spray area larger.

[0023] See Figures 4-8 The water supply pipe body 1 is also connected to an outer cylinder 9. The outer cylinder 9 extends into the channel and coincides with the axis of the channel. A baffle 11 is vertically slidably connected to the outer wall of the outer cylinder 9. The baffle 11 is hollow and has buoyancy. The outer ring wall of the baffle 11 is close to the inner wall of the outer shell 2. A cavity 21 is opened in the outer cylinder 9. A strip opening 19 communicating with the cavity 21 is opened through the outer cylinder 9. A pull rope 24 is provided inside the cavity 21. One end of the pull rope 24 extends into the first slide rail 15 and is connected to the protrusion, and the other end is connected to the inner ring wall of the baffle 11. When the baffle 11 moves vertically with the change of water pressure, the pull rope 24 pulls the protrusion to slide back and forth along the first slide rail 15.

[0024] Please see Figure 6 The outer wall of the transmission rod 12 does not contact the inner wall of the cavity 21. The circumference of the cavity 21 is greater than the circumference of the transmission rod 12. The baffle 11 can slide vertically along the outer cylinder 9. When the water pressure is low, the baffle 11 will float in the water and be closer to the top of the outer cylinder 9. When the water pressure increases, the water pressure will push the baffle 11 to slide downward. While the baffle 11 slides downward, it will drive the end of the pull rope 24 away from the protrusion to move downward and closer to the protrusion. As the downward-moving pull rope 24 gradually relaxes its pull on the protrusion, the protrusion will slide along the inclined slope of the rotating plate 13 to the outer edge of the rotating plate 13. When the water pressure is low, the baffle 11 floats up, so the baffle 11 slides upward, thereby pulling the pull rope 24 and the protrusion to move upward, so that the protrusion slides back along the first slide 15 towards the direction of the transmission rod 12. At this time, the protrusion is farther away from the diversion plate 7, but it can still squeeze the arched surface 702. When the protrusion presses against the arched surface 702, the angle between the arched surface 702 and the concave surface 703 will not be too large because it is close to the center of the drainage plate 7. At this time, the reduction in water pressure also means that the water flow will not be too large, so there is no need for water to flow down quickly.

[0025] See Figures 2-8The main body of the water supply pipe 1 has an opening 10 that communicates with the channel. A water leakage plate 5 is fixedly installed on the inner wall of the opening 10. The water leakage plate 5 is fixedly connected to the outer wall of the outer cylinder 9. The transmission rod 12 is located in the cavity 21. The circumference of the transmission rod 12 is smaller than the circumference of the inner wall of the cavity 21. The pull rope 24 is located between the transmission rod 12 and the cavity 21. A fixing rod 4 is also provided in the transmission rod 12. The top end of the fixing rod 4 is fixedly connected to the inner wall of the main body of the water supply pipe 1. The bottom end of the fixing rod 4 is fixedly connected to the middle of the top of the diverting plate 7. The transmission rod 12 and the impeller 3 are rotatably connected to the outer wall of the fixing rod 4.

[0026] The top of the fixing rod 4 is fixedly connected to the inner wall of the water supply pipe body 1. The axial direction of the fixing rod 4 coincides with the axis inside the outer shell 2. Therefore, the fixing rod 4 is located in the center of the channel. The impeller 3 and the transmission rod 12 are rotatably connected to the outer wall of the fixing rod 4. The outer ring wall of the water leakage plate 5 is fixedly connected to the inner ring wall of the through hole 10. Then, the outer cylinder 9 is fixed in the middle part of the water leakage plate 5. The bottom end of the outer cylinder 9 extends into the channel of the outer shell 2. The transmission rod 12 is inserted into the interior of the outer cylinder 9. The diversion plate 7 is fixed to the bottom of the outer shell 2 by the fixing rod 4.

[0027] See Figures 7-8 A fixed plate 131 is fixedly installed on the inner ring wall of the rotating plate 13. The fixed plate 131 has multiple first water passage holes 132 through it. The inner ring wall of the fixed plate 131 is fixedly connected to the outer wall of the transmission rod 12.

[0028] Please see Figure 7 and Figure 8 The rotating plate 13 includes a fixed disk 131 located at the center of the rotating plate 13. The inner ring wall of the fixed disk 131 is directly fixedly connected to the outer wall of the transmission rod 12, so that when the transmission rod 12 rotates, it can drive the rotating plate 13 to rotate together.

[0029] See Figures 5-13 The outer cylinder 9 has multiple second water passage holes 18 that communicate with the cavity 21. The multiple second water passage holes 18 are arranged vertically at equal intervals along the direction of the outer cylinder 9. The inner wall of the cavity 21 is vertically slidably connected to a support ring 29. The top and bottom of the support ring 29 are provided with annular through grooves 31. An annular embedding groove 30 is provided inside the support ring 29. A sliding block 32 is slidably connected inside the annular embedding groove 30. The end of the pull rope 24 away from the protrusion is fixedly connected to the bottom of the sliding block 32. The inner ring wall of the baffle 11 is provided with an annular embedded sliding groove 111. A connecting rod 112 is slidably connected in the annular embedded sliding groove 111. One end of the connecting rod 112 away from the annular embedded sliding groove 111 passes through the strip opening 19 and is fixedly connected to the outer wall of the support ring 29.

[0030] Multiple second water passage holes 18 are opened in the outer cylinder 9 and are connected to the cavity 21. Then, the water in the outer shell 2 needs to enter the cavity 21 through the second water passage holes 18 first, and then pass through the first water passage hole 132 before falling onto the guide plate 7. The diameters of the second water passage holes 18 and the first water passage hole 132 are very small, which mainly applies resistance to the water, so that the water falls onto the guide plate 7 slowly and not at a fast flow rate. Since water needs to flow out through the second water passage 18, when the water pressure is low, although the baffle 11 is higher, the upper part of the second water passage 18 will also be exposed. The multiple second water passages 18 are arranged vertically. When the water pressure increases, the water pressure will push the baffle 11 to slide downward, so that more second water passages 18 can be exposed to allow water to flow out of the outer shell 2. As the baffle 11 slides downward, it drives the support ring 29 to slide downward together through the connecting rod 112, so that the end of the pull rope 24 away from the protrusion moves downward and closer to the protrusion. Since the rotating plate 13 will rotate, in order to prevent the pull rope 24 from getting tangled on the transmission rod 12, the end of the pull rope 24 away from the protrusion is fixed to the bottom of the sliding block 32. In this way, when the rotating plate 13 rotates, the pull rope 24 will rotate together with the first slide rail 15, and then the sliding block 32 will slide in the annular embedded groove 30, so that the pull rope 24 can rotate around the transmission rod 12.

[0031] See Figure 9 The protrusion includes a push block 14. The inner walls of both sides of the first slide 15 are provided with second slides 28. A slide rod 16 is slidably connected between the two second slides 28. The push block 14 is fixedly connected to the outer wall of the slide rod 16. One end of the pull rope 24 extends into the first slide 15 and is fixedly connected to the outer wall of the slide rod 16.

[0032] As the pusher 14 presses against the arched surface 702, the pull rope 24 gradually relaxes its pull on the slide rod 16 and the pusher 14. The slide rod 16 will slide along the slope of the rotating plate 13 towards the outer edge of the rotating plate 13. When the slide rod 16 slides, both ends slide along the second slide rail 28, while the pusher 14 slides along the first slide rail 15 towards the outer edge of the rotating plate 13. When the pull rope 24 moves up and pulls the slide rod 16 and the pusher 14, the pusher 14 slides along the first slide rail 15 towards the middle of the rotating plate 13.

[0033] See Figure 11 The drainage plate 7 also includes a core 701, which is located at the center of the drainage plate 7. The inner wall of the concave surface 703 is provided with multiple diversion channels 704, one end of which extends to the outer edge of the concave surface 703 and the other end extends to the edge of the core 701.

[0034] As the center of the drainage plate 7, the core 701 allows water inside the outer shell 2 to fall onto the core 701 first. Then, when a certain concave surface 703 is tilted, the water flows directly from the core 701 into the corresponding tilted concave surface 703. Multiple diversion channels 704 are opened in the concave surface 703, so that after the water enters the concave surface 703, it can be dispersed by multiple diversion channels 704, and will not be concentrated into a single water flow. This further disperses the water, expands the dripping range, and allows for drip irrigation of more Forsythia seedlings, so that the installation of the outer shell 2 does not need to be too dense. See Figures 5-7 A connecting ring 8 is fixedly installed on the outer edge of the rotating plate 13. An annular slider 801 is fixedly installed on the inner ring wall of the connecting ring 8. A slide rail 802 is fixedly installed on the outer wall of the outer shell 2. The annular slider 801 is slidably connected to the slide rail 802. An annular groove 27 is opened on the outer wall of the outer cylinder 9. The annular groove 27 is close to the bottom end of the outer cylinder 9. A collar 25 is fixedly installed on the inner ring wall of the rotating plate 13. An embedded ring 26 extending into the annular groove 27 is fixedly installed on the inner ring wall of the collar 25. The embedded ring 26 is slidably connected to the annular groove 27. There is a gap between the bottom end of the collar 25 and the top of the fixed plate 131. One end of the first slide rail 15 is located at the gap. The pull rope 24 passes through the gap and extends into the first slide rail 15.

[0035] The connecting ring 8 is fixedly connected to the outer ring wall of the rotating plate 13. The slide rail 802 is fixed on the outer wall of the outer shell 2. When the rotating plate 13 rotates, the connecting ring 8 will rotate together. At the same time, the connecting ring 8 slides along the slide rail 802 through the annular slider 801. The connecting ring 8 provides support for the rotating plate 13. The collar 25 fixed on the inner ring wall of the rotating plate 13 will also slide along the annular groove 27 through the embedded ring 26 when the rotating plate 13 rotates, providing further support for the rotating plate 13.

[0036] See Figure 5 The outer shell 2 has a first spiral groove 6, the outer wall of the first spiral groove 6 protruding outward from the outer periphery of the outer shell 2. The outer wall of the outer cylinder 9 has a second spiral groove 17 that matches the pitch of the first spiral groove 6. The outer wall of the outer cylinder 9 also has a strip groove 20, the two ends of the strip groove 20 connecting to the two ends of the second spiral groove 17. The strip opening 19 and the second water passage hole 18 are both opened in the strip groove 20. The outer ring wall of the baffle 11 is fixedly installed with a first sliding ball 22 extending into the first spiral groove 6. The first sliding ball 22 is slidably connected to the first spiral groove 6. The inner ring wall of the baffle 11 is fixedly installed with a second sliding ball 23 extending into the second spiral groove 17. The second sliding ball 23 is slidably connected to the second spiral groove 17. The first spiral groove 6 is made of glass.

[0037] The spiral angles of the first spiral groove 6 and the second spiral groove 17 are adapted to each other. The baffle 11 is slidably connected between the first spiral groove 6 and the second spiral groove 17. The outer ring wall of the baffle 11 is slidably connected to the first spiral groove 6 through the first sliding ball 22. The inner ring wall of the baffle 11 extends into the second spiral groove 17 through the second sliding ball 23 and is slidably connected to the second spiral groove 17. When the baffle 11 moves up or down, the baffle 11 will rotate due to the sliding with the first spiral groove 6 and the second spiral groove 17. The first sliding ball 22 will slide along the first spiral groove 6, and the second sliding ball 23 will also slide along the second spiral groove 17. The baffle 11 has buoyancy, so it can move upward after the water pressure decreases. The first spiral groove 6 can be made of transparent glass, while the first slider 22 can be made of a bright color, such as red. In this way, if the first slider 22 is found to be in the lower part of the first spiral groove 6 for a long time after the water pressure drops, it means that there is no water in the outer shell 2, or that the water supply pipe body 1 is leaking or has other malfunctions that prevent water from being delivered normally. This can be detected and repaired. After water enters the cavity 21 through the second water passage 18, it can fall through the annular groove 31 and the support ring 29 will not block the flow of water.
