Description

Technical Field

[0001] This invention relates to the field of agricultural engineering technology, specifically to a new energy intelligent irrigation device based on smart agriculture. Background Technology

[0002] Traditional agricultural irrigation suffers from serious water waste, high costs and environmental problems due to reliance on traditional energy sources, and low efficiency of manual management. However, with the development of smart agriculture, the advancement of new energy technologies, and the pursuit of precise and green agricultural production, new energy intelligent irrigation devices based on smart agriculture have emerged to overcome the shortcomings of traditional irrigation. These devices combine smart agriculture concepts, new energy technologies, and intelligent control technologies to achieve efficient irrigation.

[0003] Currently, the most commonly used type of sprinkler in outdoor agriculture is the oscillating sprinkler, which uses left and right oscillation during irrigation to allow water to alternately cover the areas on both sides. Since the outdoor scenarios of smart agriculture need to meet the irrigation needs of large areas of farmland, there are higher requirements for spraying distance and range. Therefore, atomized spraying is not used to avoid the wind blowing away the water mist and the sun accelerating the evaporation of the water mist.

[0004] However, the swing sprinkler system that currently uses multiple water jets also has limitations. When it swings to a vertically upward angle, the water jets rise vertically and not only concentrate around the sprinkler when they fall, but also the water jets are easily dispersed by the wind when they reach a high altitude. Furthermore, temperature changes and air flow at high altitudes can accelerate the evaporation of droplets, causing some water to be lost before it comes into contact with the soil, resulting in a waste of water resources. Summary of the Invention

[0005] The purpose of this invention is to provide a new energy intelligent irrigation device based on smart agriculture to solve the problems mentioned in the background art.

[0006] To address the aforementioned technical problems, this invention provides a new energy intelligent irrigation device based on smart agriculture, comprising a swing sprinkler body and a swing spray pipe reciprocatingly connected to the swing sprinkler body with respect to the central axis of the swing sprinkler body. Multiple nozzles are spaced apart along the length of the swing spray pipe, and each nozzle includes...

[0007] The nozzle housing has a channel that runs through it perpendicular to the length of the oscillating spray pipe. A flow divider is connected to the end of the nozzle housing away from the oscillating spray pipe. The flow divider is elastic.

[0008] The telescopic component is located inside the nozzle housing. The telescopic end of the component is connected to the flow divider, and the bottom of the telescopic end is magnetic.

[0009] The electromagnetic drive unit is located inside the telescopic component and is positioned opposite to the bottom of the telescopic end. When the swing spray pipe swings to the middle position, the electromagnetic drive unit is energized and attracts the telescopic end. Under the combined action of the electromagnetic drive unit and the water flow, it controls the reciprocating movement of the telescopic end, causing the diverter plate to deform into a concave or convex state.

[0010] Furthermore, the telescopic component also includes,

[0011] The outer cylinder is coaxially arranged with the nozzle housing. A chamber is opened inside the outer cylinder. The electromagnetic drive unit is horizontally arranged in the chamber and is used to divide the chamber into a sliding chamber and a sealing chamber. The sliding chamber is located above the sealing chamber.

[0012] The telescopic rod is slidably connected inside the sliding cavity. The top end of the telescopic rod passes through the top end of the outer cylinder and connects to the middle of the diverter plate. The bottom end of the telescopic rod is elastic.

[0013] The electromagnetic drive unit includes a partition connected to the inner wall of the cavity. An electromagnet that is magnetically attracted to the bottom end of the telescopic rod is installed inside the partition. A rotatable triggering mechanism is provided inside the sealed cavity. Electrode plates are provided on the bottom of the partition and on the triggering mechanism, so that the two electrode plates alternately contact and separate after the triggering mechanism rotates. The electrode plates are electrically connected to the electromagnet.

[0014] Furthermore, a flow guide channel body is also provided on the outer cylinder, extending from the bottom end of the outer cylinder towards its top end. The flow guide channel body has an inlet and an outlet, and a steering component is provided at the junction of the inlet and outlet. This steering component is used to trigger the mechanism to rotate and then alternately open or close the inlet and outlet.

[0015] The telescopic rod has a cavity that communicates with the sliding cavity, and the cavity and the sliding cavity communicate to form a water storage cavity that is connected to the main body of the flow channel.

[0016] Furthermore, the water storage cavity is also provided with an elastic element, the bottom end of which is connected to the inner bottom wall of the cavity, and the top end of which is connected to the inner top wall of the sliding cavity.

[0017] Furthermore, the elastic element is a tubular structure with annular corrugated structure, and an inner cavity is provided inside. The top of the elastic element is provided with a water inlet, which is connected to the main body of the guide channel.

[0018] Furthermore, the main body of the flow guiding channel extends from the bottom end of the outer cylinder to the top of the sliding cavity and over the top of the sliding cavity. The sliding cavity has an opening that communicates with the water storage cavity, and the water inlet of the elastic element is connected to the opening.

[0019] The inlet is located at the bottom of the outer cylinder, and the outlet extends through the outer wall of the outer cylinder and is close to the inlet.

[0020] Furthermore, the triggering mechanism also includes a swing ball, the electrode plates on the triggering mechanism are connected to the outer wall of the swing ball, a counterweight is installed at the bottom of the swing ball, and an arc-shaped rack is installed on the outer wall of the swing ball;

[0021] The steering components also include,

[0022] The main body of the steering ball and the receiving cavity opened on the outer cylinder, wherein the main body of the steering ball is embedded in the receiving cavity, the receiving cavity is located at the junction of the main body of the guide channel and the outlet, and the main body of the steering ball is provided with a three-way channel.

[0023] The outer cylinder is also provided with an annular through groove that communicates with the sealing cavity. The annular through groove is located on the periphery of the receiving cavity. A connecting ring is installed on the outer wall of the steering ball body. Multiple protruding teeth are hinged at equal intervals on the outer ring wall of the connecting ring. The connecting ring and the protruding teeth are located in the annular through groove. The protruding teeth can swing in the opposite direction of the rotation of the steering ball body. The protruding teeth mesh with the arc-shaped rack.

[0024] The inner wall of the outer cylinder is also provided with a rotating cavity, which is connected to the sealing cavity and the annular through groove. A transmission gear is rotatably connected in the rotating cavity, and the transmission gear meshes with the arc-shaped rack and the convex teeth.

[0025] Furthermore, the main body of the flow guiding channel is divided into a first flow guiding channel and a second flow guiding channel, which are distributed on the left and right sides of the swing ball. The ends of the first flow guiding channel and the second flow guiding channel away from the inlet pass over the top of the sliding cavity and intersect to form a complete flow guiding channel body;

[0026] There are two arc-shaped racks, which are symmetrically arranged and distributed on the left and right sides of the counterweight. There are also two steering components, which are symmetrically arranged on the left and right sides of the swing ball.

[0027] Furthermore, the main body of the steering ball is divided into a first steering ball and a second steering ball, and a three-way channel is opened on the first steering ball and the second steering ball, with the two three-way channels pointing in different directions.

[0028] Furthermore, a semi-circular opening is provided at the top of the outer cylinder, and the top end of the telescopic rod extends through the semi-circular opening to the outside of the outer cylinder, with the semi-circular opening slidably connected to the telescopic rod.

[0029] The bottom end of the outer cylinder is bent and arched towards the direction of the swing spray pipe, forming an outwardly protruding arc surface. The inlets of the first and second guide channels are located at the edge of the arc surface.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. In this invention, when the swinging spray pipe swings and tilts, the water flow impact causes the diverter to protrude outward. At this time, the water impact distance is far. When the swinging spray pipe swings vertically, the electromagnetic current causes the telescopic end to retract, pulling the diverter to deform and indent. The sprayed water converges towards the center and collides with each other, making the sprayed water closer to the ground. This avoids the water being sprayed too high into the air, causing it to be consumed by sunlight and crosswinds, thus reducing unnecessary waste of water resources.

[0032] 2. In this invention, when the telescopic rod retracts or extends into the outer cylinder, it generates suction or thrust. Water enters the water storage chamber or leaves the outer cylinder through the main body of the guide channel. The water increases resistance, so that the telescopic rod will not retract or extend instantly, allowing the diverter plate to slowly sink or bend and protrude. Attached Figure Description

[0064] 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.

[0065] This invention provides a technical solution:

[0066] See Figures 1-21 As shown, a new energy intelligent irrigation device based on smart agriculture includes a swing sprinkler body 1 and a swing spray pipe 2 connected to the swing sprinkler body 1, which swings back and forth about the central axis of the swing sprinkler body 1. Multiple nozzles are spaced apart along the length of the swing spray pipe 2. Each nozzle includes...

[0067] The nozzle housing 3 has a channel that runs through it perpendicular to the length of the swing spray pipe 2. A flow divider 4 is connected to the end of the nozzle housing 3 away from the swing spray pipe 2. The flow divider 4 is elastic.

[0068] The telescopic component 5 is located inside the nozzle housing 3. The telescopic end of the telescopic component 5 is connected to the flow divider 4, and the bottom of the telescopic end is magnetic.

[0069] The electromagnetic drive unit is installed inside the telescopic member 5 and is positioned opposite to the bottom of the telescopic end. When the swing spray pipe 2 swings to the middle position, and its downward orthographic projection coincides with the central axis, the electromagnetic drive unit is energized and attracts the telescopic end. Under the combined action of the electromagnetic drive unit and the water flow, it is used to control the reciprocating movement of the telescopic end, causing the diverter plate 4 to deform into a concave or convex state.

[0070] Multiple branch water pipes of the main water pipe are connected to one end of multiple swing sprinkler bodies 1. Multiple swing sprinkler bodies 1 and branch water pipes are arranged in the farmland that needs irrigation. Water is injected into the main water pipe from the water source, and then flows into multiple branch water pipes. Finally, it enters the swing spray pipe 2 installed on the swing sprinkler body 1. Multiple inlets communicating with the inside of the swing spray pipe 2 are opened on the swing spray pipe 2. Multiple inlets are arranged at equal intervals on the swing spray pipe 2. After the nozzle housing 3 is inserted into the inlet, the outer wall of the nozzle housing 3 is fixedly connected to the inner wall of the inlet. Specifically, the nozzle housing 3 and the flow divider 4 can be connected by a threaded connection.

[0071] The main body 1 of the swing sprinkler has a fixed sub-assembly and a swing sub-assembly. The fixed sub-assembly is fixed on the frame of the main body 1 of the swing sprinkler, and the swing sub-assembly rotates on the fixed sub-assembly.

[0072] The oscillating component consists of two mechanisms. The first is the drive mechanism, which converts the water flow into a low-speed rotational output. The drive mechanism includes a water turbine. When the water flow enters the main body 1 of the oscillating sprinkler, it impacts the blades of the water turbine and then enters the oscillating spray pipe 2. This water impact transfers some of the water's kinetic energy to the water turbine, causing it to rotate.

[0073] The water turbine is connected to a reduction gear set to reduce its rapid rotational input speed to the slow output speed required by the oscillating spray pipe 2, so as to ensure proper water distribution. The last gear of the gear set is mounted on the fixed sub-assembly, enabling the oscillating sub-assembly to rotate around it.

[0074] Another mechanism of the oscillating sub-assembly is a positioning mechanism for alternating the rotation direction of the turbine. Specifically, it includes a sliding baffle. The sliding baffle is mounted on the fixed sub-assembly through a rotation positioning mechanism. The teeth on the baffle body mesh with the tooth grooves on the oscillating sub-assembly. Slight meshing resistance allows the baffle to be temporarily fixed in a certain position. When the oscillating sub-assembly drives the oscillating spray pipe 2 to swing to one side to the maximum angle, the protrusion on the oscillating sub-assembly will hit the sliding baffle. At this time, the meshing of the teeth and tooth grooves is forcibly pushed open, the sliding baffle is displaced and triggers the positioning mechanism. Through gear transmission, it acts in the opposite direction on the drive mechanism, causing the rotation direction of the oscillating sub-assembly to reverse, driving the oscillating spray pipe 2 to swing to the other side.

[0075] When the swing spray pipe 2 swings to the maximum angle on the other side, the same positioning logic is triggered again, and the swing direction is reversed again. This cycle repeats, and the swing spray pipe 2 achieves stable left and right reciprocating swing under the power output of the drive mechanism and the directional control of the positioning mechanism.

[0076] Please see Figure 5 After water enters the nozzle housing 3, it passes through the diverter 4 and is sprayed out. The telescopic component 5 is fixed inside the nozzle housing 3 by a fixed bracket. The telescopic component 5 is centrally located on the central axis inside the nozzle housing 3. The outer ring wall of the diverter 4 is fixedly connected to the inner ring wall of the nozzle housing 3. Figure 3 and Figure 4 The middle part represents two different states of the shunt 4. Figure 3 The flow divider 4 is in a concave state, and at this time, the outer arc surface of the swing spray pipe 2 faces upward, and the swing spray pipe 2 is in a vertical or nearly vertical state. Figure 4 The flow divider 4 is in the state of arching outwards. At this time, the swing spray pipe 2 is in the tilted state. No matter whether the swing spray pipe 2 swings to the left or the right, the flow divider 4 is in the state of arching outwards.

[0077] The perimeter of the telescopic component 5 is smaller than the diameter of the nozzle housing 3. Water passes around the telescopic component 5 and reaches the diverter plate 4. Multiple perforations are opened through the diverter plate 4 to allow water to pass through and to divert the water so that the sprayed water is not in the form of a water column.

[0078] The telescopic component 5 limits the extension and retraction direction of the telescopic end, ensuring that the telescopic end can only reciprocate along the axis of the telescopic component 5 and the nozzle housing 3. When the telescopic end extends away from the telescopic component 5, the middle part of the flow divider 4 is lifted, causing the flow divider 4 to arch. When the telescopic end retracts, it pulls the middle part of the flow divider 4 inward toward the direction of the swing spray pipe 2. Figure 1 and Figure 2 The oscillating spray pipe 2 has a curved arched part that forms an outer arc surface. When the oscillating spray pipe 2 oscillates until its outer arc surface faces upward, the electromagnetic drive unit opens and attracts the telescopic end to retract into the nozzle housing 3 and magnetically attract it to the electromagnetic drive unit.

[0079] At this time, you can see Figure 8 After the telescopic end retracts, it pulls the diverter plate 4 downward, causing it to become concave. When the swinging spray pipe 2 swings until its outer arc surface tilts, the electromagnetic drive unit disconnects the power supply, canceling the magnetic attraction to the telescopic end. Then, using the impact on the diverter plate 4, it pushes the diverter plate 4 to bend and arch upward again. (This can be seen...) Figure 7 ;

[0080] When the water spray direction of the oscillating spray pipe 2 and the nozzle housing 3 is upward, the diverter 4 is in a concave state. At this time, the curved surface of the diverter 4 faces the inside of the water flow. After the water flow impacts the concave surface, it will be guided by a force converging towards the center. Since the middle of the diverter 4 is connected to the telescopic end, the center of the diverter 4 does not spray water. The spraying holes are around the telescopic end. After the diverter 4 is concave, the sprayed water will converge towards the central axis of the telescopic end and then collide with each other. After the collision, the horizontal range of the water flow is greatly shortened and the kinetic energy is consumed. More water will fall directly or splash around the oscillating spray pipe 2.

[0081] This prevents water from being sprayed too high into the air when the nozzle housing 3 is facing upwards, reducing the chances of water being evaporated by sunlight and blown away by the wind. The recessed diverter plate 4 makes the water sprayed when the nozzle housing 3 is facing upwards closer to the ground, reducing unnecessary waste of water resources.

[0082] After the nozzle housing 3 is tilted, the electromagnetic drive unit is turned off, causing the diverter plate 4 to slowly flatten outward or arch slightly due to the impact of the water. The arching angle is not very large and will not exceed the concave angle of the diverter plate 4. After the diverter plate 4 arches, the water is naturally sprayed outward without colliding with each other and consuming the spraying range. Because the swing spray pipe 2 will be close to the ground after tilting, the water spraying range can be extended to ensure the spraying distance.

[0083] See Figures 6-14 The telescopic component 5 also includes,

[0084] The outer cylinder 501 is coaxially arranged with the nozzle housing 3. A chamber is opened inside the outer cylinder 501. The electromagnetic drive unit is horizontally arranged in the chamber and is used to divide the chamber into a sliding chamber 5011 and a sealing chamber 5012. The sliding chamber 5011 is located above the sealing chamber 5012.

[0085] The telescopic rod 502 is slidably connected in the sliding cavity 5011. The top end of the telescopic rod 502 passes through the top end of the outer cylinder 501 and is fixedly connected to the middle of the diverter plate 4. The bottom end of the telescopic rod 502 is elastic.

[0086] The electromagnetic drive unit includes a partition 9 fixedly connected to the inner wall of the cavity. An electromagnet is installed inside the partition 9 and is magnetically attracted to the bottom end of the telescopic rod 502. A rotatable triggering mechanism 8 is provided inside the sealed cavity 5012. Electrode plates are provided on the bottom of the partition 9 and on the triggering mechanism 8, so that the two electrode plates alternately contact and separate after the triggering mechanism 8 rotates. The electrode plates are electrically connected to the electromagnet.

[0087] The method of triggering the electromagnet is not unique. To better suit this structure, a reflective photoelectric sensor electrically connected to the electromagnet can be fixedly installed at the bottom of the partition 9, and then a reflector can be installed on the triggering mechanism 8. When the swinging spray pipe 2 swings so that its outer arc faces the vertical direction, the area near the vertical square can also be used.

[0088] For example, when the swinging spray pipe 2 swings to the vertical position of the outer arc surface, it is 90 degrees. Then, it can also be triggered after the swinging spray pipe 2 swings to 70 degrees. After the triggering mechanism 8 rotates, the reflector enters the sensing area of ​​the reflective photoelectric sensor. After the reflective photoelectric sensor detects the reflected signal and outputs an electrical signal, this electrical signal can be used as a control signal to trigger the circuit to conduct, thereby energizing the electromagnet. In this way, the triggering mechanism 8 does not need to touch the partition 9.

[0089] The telescopic component 5 consists of an outer cylinder 501 and a telescopic rod 502. The outer cylinder 501 is fixed inside the nozzle housing 3 by a fixing bracket, while the telescopic rod 502 is inserted into the outer cylinder 501 from the top. Figure 9 It shows a cross-sectional view of the outer cylinder 501 and a schematic diagram showing its separation from the telescopic rod 502. Figure 11 and Figure 12 This is a side sectional view of the outer cylinder 501 and the telescopic rod 502 when they are connected. Figure 10 In the middle, the outer cylinder 501 has a complete cylindrical shape, and then... Figure 9 The top and bottom of the telescopic rod 502 are closed circles, and the middle area of ​​the telescopic rod 502 is a half cylinder.

[0090] Please see Figure 11 and Figure 12 The telescopic rod 502 has a cavity 5021. The chamber inside the outer cylinder 501 is separated by a partition 9. The partition 9 is fixedly connected to the inner wall of the chamber. Above the partition 9 is a sliding cavity 5011, and below the partition 9 is a sealed cavity 5012. The telescopic rod 502 slides in the sliding cavity 5011. When the trigger mechanism 8 rotates and causes the reflector to enter the sensing area of ​​the reflective photoelectric sensor, the electromagnet is energized. Then, it attracts the bottom end of the telescopic rod 502 to slide towards the partition 9 and abut against the top of the partition 9. Then, the telescopic rod 502 will pull the diverter 4 to deform and indent. The magnetic attraction strength between the electromagnet and the bottom end of the telescopic rod 502 is greater than the impact strength of the water flow on the diverter 4.

[0091] In the initial state, that is, before water is introduced, the bottom of the telescopic rod 502 is in contact with the top partition 9. After water is introduced, the water pushes the diverter plate 4 to arch up, and then the telescopic rod 502 slides in the sliding cavity 5011. At this time, the swing spray pipe 2 is in an inclined state when it is turned on.

[0092] See Figures 7-17 The outer cylinder 501 is also provided with a flow channel body 6, which extends from the bottom end of the outer cylinder 501 to its top end. The flow channel body 6 is provided with an inlet 601 and an outlet 602. A steering component 7 is provided at the junction of the inlet 601 and the outlet 602, which is used to trigger the steering component 7 to alternately open or close the inlet 601 and the outlet 602 after the trigger mechanism 8 rotates.

[0093] When the swing spray pipe 2 is tilted, the inlet 601 is closed and the outlet 602 is open; when it is upright, the outlet 602 is closed and the inlet 601 is open.

[0094] The telescopic rod 502 has a cavity 5021 that communicates with the sliding cavity 5011. The cavity 5021 and the sliding cavity 5011 communicate to form a water storage cavity 503 that communicates with the main body of the flow channel 6.

[0095] The cavity 5021 inside the telescopic rod 502 coincides with the sliding cavity 5011, forming a water storage cavity 503. Water enters the nozzle housing 3 and instantly fills it. Figure 8 Water enters the main body of the flow channel 6 through the inlet 601 located at the bottom of the outer cylinder 501, and then flows into the water storage chamber 503 along the main body of the flow channel 6. Figure 11 The middle position is the state after the telescopic rod 502 is retracted. At this time, the space of the water storage chamber 503 becomes larger. Figure 12 The middle position is the state after the telescopic rod 502 is extended, at which point the water storage chamber 503 becomes smaller;

[0096] Please see Figure 13The main body of the flow channel 6 extends from the bottom end of the outer cylinder 501 toward the top end of the outer cylinder 501. After it is about to reach the top end of the outer cylinder 501, it makes a right-angle turn and then connects with the water storage chamber 503. In this way, after the water enters the main body of the flow channel 6, it can enter the water storage chamber 503. The triggering mechanism 8 will rotate due to the change in the swing angle of the swing spray pipe 2, which in turn changes the center of gravity. When the outer arc surface of the swing spray pipe 2 is facing upward, the telescopic rod 502 slides down.

[0097] A rubber ring is installed on the outer wall of the telescopic rod 502, and it fits tightly against the inner wall of the sliding cavity 5011. This allows it to generate suction force on the water storage cavity 503 when sliding downwards along the inner wall of the sliding cavity 5011. (See...) Figure 15 As the oscillating spray pipe 2 oscillates into a near-vertical state, the rotating trigger mechanism 8 also triggers the steering component 7 to open the inlet 601. Then, due to the suction generated by the movement of the telescopic rod 502, the water in the nozzle housing 3 is sucked into the guide channel body 6 through the inlet 601 and then enters the water storage chamber 503 along the guide channel body 6. As the telescopic rod 502 continues to slide down and the water continuously enters the water storage chamber 503, the water storage chamber 503 expands, and at the same time, it pulls the middle part of the diverter plate 4 downward to deform, so that the diverter plate 4 is pulled into a concave state.

[0098] Because the downward movement of the telescopic rod 502 generates negative pressure and requires the intake of water, when the electromagnet is energized to attract the telescopic rod 502, the telescopic rod 502 will not slide towards the partition 9 very quickly, but will slowly approach the partition 9. Thus, when the swing spray pipe 2 swings to about 70 degrees, the electromagnet opens, and then the telescopic rod 502 gradually slides down, and the diverter plate 4 gradually sinks, instead of sinking directly. Thus, after the angle of the swing spray pipe 2 reaches 90 degrees, the diverter plate 4 is in the most concave state.

[0099] When the swing angle of the swing spray pipe 2 is below 70 degrees, the trigger mechanism 8 rotates, the reflector leaves the sensing area of ​​the reflective photoelectric sensor, and then the power supply to the electromagnet is turned off. At this time, the water impacts the diverter plate 4, which will pull the telescopic rod 502 upward. Then the trigger mechanism 8 triggers the steering component 7 to close the inlet 601 and open the outlet 602. Then the upward telescopic rod 502 will squeeze the water in the water storage chamber 503 out, and the water will return to the guide channel body 6 and then flow from the outlet 602 into the nozzle housing 3.

[0100] Due to the presence of water, there will be resistance to the upward movement of the telescopic rod 502. Therefore, the telescopic rod 502 will move upward slowly, and the diverter 4 will not immediately return to flat or arch. Only after the swing spray pipe 2 swings to a horizontal state will the diverter 4 arch to its maximum angle.

[0101] See Figures 9-12The water storage cavity 503 is also provided with an elastic element 10. The bottom end of the elastic element 10 is fixedly connected to the inner bottom wall of the cavity 5021, and the top end of the elastic element 10 is fixedly connected to the inner top wall of the sliding cavity 5011.

[0102] The elastic element 10 is installed inside the water storage chamber 503. The elastic force of the elastic element 10 is less than the force of water impacting the diverter plate 4. When the telescopic rod 502 moves upward, the water storage chamber 503 shrinks and the elastic element 10 is compressed. When the telescopic rod 502 moves downward, the water storage chamber 503 expands and the elastic element 10 also extends. The initial state of the elastic element 10 is extended. When the telescopic rod 502 moves downward, the elastic element 10 can use its own elasticity to accelerate the downward movement of the telescopic rod 502, making the water absorption speed faster. Because the swing spray pipe 2 tilts to both sides for a longer time than in the vertical state, the telescopic rod 502 needs to move downward faster. This ensures that when the swing angle of the swing spray pipe 2 reaches 90 degrees, the diverter plate 4 can be recessed at a larger angle.

[0103] See Figures 9-12 The elastic element 10 is a tubular structure with an annular corrugated structure and an inner cavity. The top of the elastic element 10 has a water inlet, which is connected to the main body 6 of the guide channel.

[0104] The elastic element 10 is hollow, so that when the elastic element 10 rebounds, it can help to absorb water. Water enters the elastic element 10 directly through the main body 6 of the guide channel, making the water absorbed faster. This further ensures that when the swing angle of the swing spray pipe 2 reaches 90 degrees, the diverter plate 4 can be recessed at a larger angle.

[0105] See Figures 7-21 The main body of the flow channel 6 extends from the bottom of the outer cylinder 501 to the top of the sliding cavity 5011 and over the top of the sliding cavity 5011. The sliding cavity 5011 is provided with an opening 603 that communicates with the water storage cavity 503. The water inlet of the elastic element 10 is connected to the opening 603.

[0106] The inlet 601 is located at the bottom of the outer cylinder 501, and the outlet 602 extends through to the outer wall of the outer cylinder 501 and is close to the inlet 601.

[0107] Please pay close attention. Figure 11 and Figure 12 After water enters the main body 6 of the flow channel, it enters the elastic element 10 through the opening 603. When water is squeezed out, it also enters the main body 6 of the flow channel through the opening 603. Then please see... Figure 13 Since water enters the nozzle housing 3 from the bottom up from the swing spray pipe 2, the position of the inlet 601 corresponds exactly to the direction of the water flow. This makes it easier for the water to enter the main body of the guide channel 6 directly and quickly. The outlet 602 is on the side of the outer cylinder 501, which is not in the direction of water impact, thus facilitating water discharge. This is mainly to avoid the direction of water impact, which would affect the speed of water discharge.

[0108] See Figures 14-21 The triggering mechanism 8 also includes a swing ball 801. The electrode plate on the triggering mechanism 8 is fixedly connected to the outer wall of the swing ball 801. A counterweight 802 is fixedly installed at the bottom of the swing ball 801. The electrode plate is located on the side of the swing ball 801 opposite to the counterweight 802. An arc-shaped rack 803 is fixedly installed on the outer wall of the swing ball 801.

[0109] Steering component 7 also includes,

[0110] The steering ball body 701 and the receiving cavity 702 opened on the outer cylinder 501 are included. The steering ball body 701 is embedded in the receiving cavity 702. The receiving cavity 702 is located at the junction of the guide channel body 6 and the outlet 602. The steering ball body 701 is provided with a three-way channel 703.

[0111] The outer cylinder 501 is also provided with an annular through groove 704 that communicates with the sealing cavity 5012. The annular through groove 704 is located on the periphery of the receiving cavity 702. A connecting ring 705 is fixedly installed on the outer wall of the steering ball body 701. Multiple protruding teeth 706 are hinged at equal intervals on the outer ring wall of the connecting ring 705. The connecting ring 705 and the protruding teeth 706 are located in the annular through groove 704. The protruding teeth 706 can swing in the opposite direction of the rotation of the steering ball body 701. The protruding teeth 706 are engaged with the arc-shaped rack 803.

[0112] The inner wall of the outer cylinder 501 is also provided with a rotating cavity, which is connected to the sealing cavity 5012 and the annular through groove 704. A transmission gear 707 is rotatably connected in the rotating cavity, and the transmission gear 707 meshes with the arc-shaped rack 803 and the convex tooth 706.

[0113] The outer wall of the steering ball body 701 is in close contact with the inner wall of the receiving cavity 702. The three-way channel 703 is located inside the receiving cavity 702. The swing ball 801 is rotatably connected to the inner wall of the sealing cavity 5012 by a first rotating shaft 13. The steering ball body 701 is rotatably connected to the inner wall of the receiving cavity 702 by a second rotating shaft 14. There is a gap between the connecting ring 705 and the three-way channel 703.

[0114] Please see Figure 14 and Figure 15 At this time, the swing spray pipe 2 and the nozzle housing 3 are in a vertical state, the counterweight 802 has weight and is in a downward state. At this time, the vertical channel of the three-way channel 703 connects the inlet 601 and the main body of the guide channel 6, and the outlet 602 is in a closed state. Then, the horizontal channel of the three-way channel 703 corresponds to the inner wall of the receiving cavity 702, and the outer wall of the three-way channel 703 is in contact with the inner wall of the receiving cavity 702. At this time, water will first enter the inlet 601, then enter the three-way channel 703, and then enter the main body of the guide channel 6.

[0115] Then look Figure 16 or Figure 17 , Figure 16 and Figure 17 This is the state after the telescopic component 5 is tilted. At this time, the counterweight 802 will turn downwards due to gravity, and then the swing ball 801 will rotate. At the same time, the arc rack 803 will rotate together with the swing ball 801. At this time, the three-way channel 703 connects the main body of the guide channel 6 with the outlet 602. The inlet 601 is closed. At this time, water will enter the three-way channel 703 from the main body of the guide channel 6 and then flow out through the outlet 602.

[0116] Please see Figure 20 One end of the protruding tooth 706 is hinged to the connecting ring 705. The end of the protruding tooth 706 that contacts the connecting ring 705 has a flat surface. This flat surface abuts against the outer ring wall of the connecting ring 705, preventing the protruding tooth 706 from swinging in the direction of the flat surface. Thus, when the arc-shaped rack 803 rotates with the swing ball 801... Figure 20 The arc-shaped rack 803 in the field of view will swing up or down. When the arc-shaped rack 803 swings up, it will push the convex tooth 706 to move upward, thereby causing the connecting ring 705 and the steering ball body 701 to rotate clockwise.

[0117] When the oscillating spray pipe 2 tilts to the other side, the arc-shaped rack 803 swings downward. Then, the teeth of the arc-shaped rack 803 will exert a downward force on the convex tooth 706. Since the convex tooth 706 can swing downward, the arc-shaped rack 803 cannot drive the connecting ring 705 and the steering ball body 701 to rotate counterclockwise. However, the arc-shaped rack 803 will drive the transmission gear 707 to rotate. The teeth of the transmission gear 707 will exert a thrust on the convex tooth 706 in the counterclockwise direction, so that the connecting ring 705 can rotate. Moreover, when the arc-shaped rack 803 swings upward, although it will also drive the transmission gear 707 to rotate, at this time the rotation of the transmission gear 707 will exert a force on the convex tooth 706 that causes the convex tooth 706 to rotate in the opposite direction. The convex tooth 706 will swing, so it will not drive the convex tooth 706 to rotate in the opposite direction.

[0118] Therefore, the function achieved here is that when the swing ball 801 swings counterclockwise, the arc rack 803 will directly push the convex tooth 706, causing the connecting ring 705 and the steering ball body 701 to rotate clockwise. When the swing ball 801 swings clockwise, it will drive the transmission gear 707 to rotate through the arc rack 803, and then drive the convex tooth 706 through the transmission gear 707, so that the connecting ring 705 and the steering ball body 701 will still rotate clockwise.

[0119] When the oscillating spray pipe 2 is tilted to the vertical distance, or from the vertical to the tilted distance, the steering ball body 701 only rotates 90 degrees, and the transmission gear 707 rotates within the annular through groove 704.

[0120] See Figures 7-21 The main body of the flow channel 6 is divided into a first flow channel 604 and a second flow channel 605, which are distributed on the left and right sides of the swing ball 801. The ends of the first flow channel 604 and the second flow channel 605 away from the inlet 601 pass over the top of the sliding cavity 5011 and intersect to form a complete flow channel main body 6.

[0121] There are two arc-shaped racks 803, which are symmetrically arranged and distributed on the left and right sides of the counterweight 802. There are two steering components 7, which are symmetrically arranged on the left and right sides of the swing ball 801.

[0122] The first guide channel 604 and the second guide channel 605 are both provided with an inlet 601 and an outlet 602. The two inlets 601 and outlets 602 work together to achieve water intake and discharge, improving the efficiency of water intake and discharge. The two arc-shaped racks 803 drive the two steering components 7 together to open or close the inlets 601 and outlets 602 on both sides.

[0123] See Figures 14-21 The main body of the steering ball 701 is divided into a first steering ball 7011 and a second steering ball 7012. The three-way channel 703 is opened on the first steering ball 7011 and the second steering ball 7012, and the two three-way channels 703 point in different directions.

[0124] Figure 15 This refers to the state of the two steering ball bodies 701 when the nozzle housing 3 and the telescopic component 5 are in a vertical position. Figure 16 and Figure 17 This refers to the state of the two steering ball bodies 701 when the nozzle housing 3 and the telescopic component 5 are tilted at two different angles. Figure 18 The angle of the three-way channel 703 when the first steering ball 7011 and the second steering ball 7012 rotate together is such that, since the first steering ball 7011 and the second steering ball 7012 always rotate in the same direction, that is, clockwise, the two three-way channels 703 have four different angles of cooperation, which can ensure that at least one inlet 601 or outlet 602 is open.

[0125] Both inlet 601 and outlet 602 can drain water or take in water. When both inlet 601 and outlet 602 are open, water can enter the main body of the guide channel 6 from both channels at the same time, and can also be discharged at the same time, further improving the efficiency of drainage and water intake.

[0126] See Figures 10-17 The top of the outer cylinder 501 is provided with a semi-circular through-hole 11, and the top end of the telescopic rod 502 extends through the semi-circular through-hole 11 to the outside of the outer cylinder 501. The semi-circular through-hole 11 is slidably connected to the telescopic rod 502.

[0127] The bottom end of the outer cylinder 501 is bent and arched in the direction of the swing spray pipe 2, forming an outwardly protruding arc surface 12. The inlets 601 of the first guide channel 604 and the second guide channel 605 are located at the edge of the arc surface 12.

[0128] The arc surface 12 is located at the bottom of the outer cylinder 501, directly facing the impact of the water flow. The arc surface of the arc surface 12 can reduce the impact force of the water flow, and at the same time, the water can easily flow into the inlet 601 after hitting the arc surface 12. The semi-annular through-hole 11 is opened through the top of the outer cylinder 501, and is used for the telescopic rod 502 to slide along the inside of the semi-annular through-hole 11 when it is extended or retracted. In order to further improve the sealing performance, a rubber sealing ring can be fixedly installed on the inner wall of the semi-annular through-hole 11. The sealing ring and the outer wall of the telescopic rod 502 are in close contact, and the telescopic rod 502 can still slide normally.
