Description

Technical Field

[0001] This invention relates to the field of sprinkler truck technology, and specifically discloses an intelligent sprinkler truck. Background Technology

[0002] As a traditional sanitation and greening maintenance vehicle, water sprinkler trucks play a vital role in the daily maintenance of urban gardens, parks, green spaces, and roadside green belts. Their main structure includes the vehicle body, tank, connector, water pump, pipeline network, working platform, and greening water cannon.

[0003] For example, the patent with announcement number CN120540410B and announcement date of 2025-10-10 discloses an intelligent water level control system for a sprinkler truck, including a frame, a water tank fixed to the top of the frame, a display screen fixedly installed at the rear of the water tank, a scissor bracket fixedly connected to the bottom of the frame, a first electric push rod fixedly connected between the frame and the scissor bracket, the frame and the spray pipe being driven by the scissor bracket, an operating platform fixedly connected to the rear of the frame, one side of the operating platform being adjacent to the rear of the water tank, and guardrails fixedly connected to the other three sides of the operating platform, with a spray gun fixedly connected to the top of the operating platform.

[0004] In existing technologies, water trucks, limited by their inherent structure, must travel along a predetermined road at a low and constant speed. At the same time, the onboard personnel need to adjust the angle of the water cannon to irrigate the green shrubs or trees on one side of the road in a sequence from far to near or from near to far. The aim is to cover as wide an area as possible in a single trip to improve the efficiency of a single operation. However, existing water trucks have a low level of intelligence, and the water output speed of the green water cannon cannot be dynamically adjusted. Therefore, while ensuring that the range can reach the irrigation distance, the impact force on the nearby irrigation point is too large, which can cause damage to plants due to the impact of the water flow or damage to the original structure of the soil, resulting in a certain amount of soil erosion. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent sprinkler truck that can dynamically adjust the water output speed.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An intelligent sprinkler truck includes a vehicle body, on which a tank, a water conveying mechanism, and a sprinkler cannon are mounted. The water conveying mechanism is used to transport water from the tank to the sprinkler cannon. The sprinkler cannon includes a cannon body, and a water outlet regulating component is installed at the end of the cannon body. The water outlet regulating component is driven to adjust the flow area of ​​the water outlet at the end of the cannon body to change the water outlet speed.

[0008] The aforementioned water truck also includes a three-way base, which is rotatably mounted on the vehicle body, and the cannon body is rotatably connected to the three-way base.

[0009] The water sprinkler truck described above has a water outlet adjustment component including a stop block that is movably installed at the end of the cannon body, which is driven to block the water outlet.

[0010] The water spraying truck mentioned above also includes an adjusting ring rotatably mounted on the cannon body and a fixed ring fixed to the cannon body. The blocks are arranged in a circumferential array at the end of the cannon body, and each block is slidably connected to the fixed ring. The adjusting ring is driven to rotate and synchronously adjusts the position of each block.

[0011] The aforementioned water truck has a distribution cavity in each block, and each block has a hole array that communicates with the distribution cavity. Each block also has a water inlet hole that communicates with the distribution cavity. When each block is driven to slide to the end of its stroke, the water inlet hole connects the inner cavity of the gun body with the distribution cavity.

[0012] The aforementioned sprinkler truck has a support column coaxially arranged on the inner side of the fixed ring. The part of the side wall of the support column that is directly opposite the fixed ring has an annular protrusion along its own circumference. When each stop block is driven to slide to the end of its stroke, the opening surface of the hole array on each stop block contacts the annular protrusion.

[0013] The aforementioned water sprinkler truck has a support column that is a cylindrical tube closed at one end. The side wall of the support column is provided with a first through groove near the closed end, and a blocking component is provided on the support column. The blocking component has a first position and a second position along the axial direction of the support column. When it is in the first position, the blocking component blocks the first through groove. When it is in the second position, the blocking component blocks the water inlet holes on each block.

[0014] The aforementioned water truck has an adjustment rod fixed to the cannon body, and a handle is installed at the end of the adjustment rod away from the cannon body.

[0015] The aforementioned water truck also has a transmission mechanism on the cannon body, and an adjustment handle is rotatably mounted on the handle. The adjustment handle is connected to the adjustment ring through the transmission mechanism.

[0016] The aforementioned water truck also has a locking mechanism on the handle for locking the adjustment lever.

[0017] In the above technical solution, the water truck provided in the embodiment of the present invention has a water outlet regulating component on its cannon body. The water outlet regulating component can adjust the flow cross-sectional area at the water outlet according to the change of irrigation distance, thereby dynamically adjusting the water flow speed at the water outlet to improve the intelligence of irrigation, ensure that the trees at the corresponding distance are always irrigated with a suitable water flow speed, protect the trees from damage, and at the same time prevent the original structure of the soil from being destroyed.

Detailed Implementation

[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] In the description of this invention, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," and "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] like Figures 1 to 12 As shown in the figure, an intelligent sprinkler truck provided by the present invention includes a vehicle body 1, on which a tank 11, a water conveying mechanism and a sprinkler cannon 2 are installed. The water conveying mechanism is used to convey water in the tank 11 to the sprinkler cannon 2. The sprinkler cannon 2 includes a cannon body 21, and a water outlet regulating component 3 is installed at the end of the cannon body 21. The water outlet regulating component 3 is driven to adjust the flow area of ​​the water outlet at the end of the cannon body 21 to change the water outlet speed.

[0036] Specifically, this sprinkler truck is mainly used for watering greenery, such as... Figure 1As shown, its main structure is a vehicle body 1, on which a tank 11 for storing water is installed. A working platform 12 is installed on the rear side of the vehicle body 1, and a water cannon 2 is installed on the working platform 12. The main structure of the water cannon 2 is a cannon body 21, which has a water outlet. A water outlet regulating component 3 is installed at the end of the cannon body 21, which is also the location of the water outlet. The water outlet regulating component 3 is used to change the flow area (effective flow cross section) at the water outlet. The vehicle body 1 is also equipped with a water conveying mechanism for conveying water from the tank 11 to the cannon body 21. This is existing technology and can be directly applied without further explanation.

[0037] During the greening maintenance process, water delivered to the cannon body 21 by the water conveying mechanism is sprayed outward from the outlet of the cannon body 21. During this process, the water outlet regulating component 3 adjusts the flow cross section of the outlet according to the change of irrigation distance. According to the continuity equation, under steady flow (the flow parameters at each point in the flow field do not change with time), the mass of fluid passing through any cross section per unit time is equal. For incompressible fluid (water), the volume of fluid passing through different cross sections per unit time is equal, i.e., Q=Av (where: A is the cross-sectional area, v is the flow velocity). When the flow area at the outlet gradually decreases, in order to maintain the same flow rate Q, the flow velocity v of the water at the outlet will increase, and vice versa.

[0038] The water sprinkler truck provided in this embodiment of the invention has a water outlet regulating component 3 installed on the water outlet of its cannon body 21. The water outlet regulating component 3 can adjust the flow cross-sectional area at the water outlet according to the change of irrigation distance, thereby dynamically adjusting the water flow speed at the water outlet to improve the intelligence of irrigation, ensure that the trees at the corresponding distance are always irrigated with a suitable water flow speed, protect the trees from damage, and at the same time prevent the original structure of the soil from being destroyed.

[0039] Furthermore, the water cannon 2 also includes a three-way base 22, which is rotatably mounted on the vehicle body 1, and the cannon body 21 is rotatably connected to the three-way base 22.

[0040] Specifically, such as Figures 1 to 3As shown, the sprinkler cannon 2 also includes a T-shaped base 22, which includes one inlet and two outlets. The cannon body 21 includes a V-shaped pipe 211 and a straight pipe 212. The open end of the V-shaped pipe 211 is bent and rotatably connected to the two outlets of the T-shaped base 22. One end of the straight pipe 212 is connected to the bottom of the V-shaped pipe 211 to ensure that water can be delivered from the V-shaped pipe 211 to the straight pipe 212. The outlet is located at the end of the straight pipe 212 away from the V-shaped pipe 211. The water delivery assembly package includes... The system includes a pipe 13 installed on the vehicle body 1. One end of the pipe 13 is connected to the inside of the tank 11, and the other end of the pipe 13 extends to the location of the working platform 12 and bends vertically upward. The water inlet end of the three-way base 22 is vertically downward, and the water inlet end of the three-way base 22 is rotatably connected to the other end of the water delivery assembly. This configuration allows the cannon body 21 to rotate on both a vertical axis and a horizontal axis, thereby enabling the operator to flexibly adjust the orientation of the water outlet for irrigation work.

[0041] In another embodiment of the present invention, the water outlet regulating member 3 includes a stop block 31 movably installed at the end of the gun body 21, and the stop block 31 is driven to block the water outlet.

[0042] Specifically, the water outlet regulating component 3 includes a stop block 31, which is movably installed on the gun body 21 at the water outlet position. Optionally, the stop block 31 is a plate parallel to the cross-section of the water outlet. The stop block 31 is rotatably installed on the water outlet end of the gun body 21, and the stop block 31 revolves around an axis parallel to the axial direction of the straight pipe 212 section of the gun body 21. The stop block 31 always rotates in the plane where the cross-section of the water outlet is located. The gun body 21 is provided with a rotary drive component for driving the stop block 31 to rotate. This allows the stop block 31 to be driven to rotate and change the flow area of ​​the water outlet. Using a rotary drive component to drive the plate to revolve around a fixed axis is existing technology and can be directly applied without further explanation.

[0043] Furthermore, the water outlet regulating component 3 also includes an adjusting ring 32 rotatably mounted on the gun body 21 and a fixing ring 33 fixedly connected to the gun body 21. The blocks 31 are arranged in a circumferential array at the end of the gun body 21, and each block 31 is slidably connected to the fixing ring 33. The adjusting ring 32 is driven to rotate and synchronously adjusts the position of each block 31.

[0044] Specifically, when water flows out from the outlet, the shape of the flow area of ​​the outlet also has a certain influence on its range; the closer it is to a columnar shape, the farther the range. In this embodiment, several sets of baffles 31 are provided, and the several sets of baffles 31 are arranged in a circular array around the central axis of the straight pipe 212. Each baffle 31 is located at the outlet position on the straight pipe 212. A fixing ring 33 is fixedly connected to the end of the straight pipe 212. The fixing ring 33 is coaxially arranged with the straight pipe 212. Each baffle 31 is slidably connected to the fixing ring 33. A guide groove 331 is opened on the fixing ring 33 corresponding to each baffle 31. Each guide groove 331 is arranged in a circular array around the central axis of the fixing ring 33. A slider 311 is fixedly connected to the contact surface between the baffle 31 and the fixing ring 33. The slider 311 is adapted to the guide groove 331. In addition, the straight pipe An adjusting ring 32 is rotatably mounted at the end of the straight tube 212. The adjusting ring 32 is coaxially arranged with the straight tube 212 and is located between the straight tube 212 and the fixed ring 33. Each stop block 31 is located between the fixed ring 33 and the adjusting ring 32. The distance between the fixed ring 33 and the adjusting ring 32 is equal to the dimension of the stop block 31 along the axial direction of the fixed ring 33. Each stop block 31 is fixedly connected to a guide post 312 on the side of the adjusting ring 32. An arc-shaped groove 321 that matches the guide post 312 is opened on the adjusting ring 32. The arc-shaped grooves 321 are arranged in a circumferential array with the central axis of the adjusting ring 32 as the center, and the arc-shaped grooves 321 and the guide posts 312 are arranged one-to-one. The guide post 312 extends into the corresponding arc-shaped groove 321 on the adjusting ring 32. In this way, the fixed ring 33, the adjusting ring 32, and each stop block 31 together constitute the iris mechanism. Figure 5 , Figure 6 , Figure 9 and Figure 10 As shown, the cross-section of the baffle 31 is approximately fan-shaped (a portion of a circular fan-shaped section). It has two straight edges, one arc-shaped edge, and one approximately arc-shaped edge. When the adjusting ring 32 is driven to rotate, one straight edge of each baffle 31 contacts the other straight edge of the adjacent baffle 31 and slides along the direction restricted by the guide groove 331. This arrangement ensures that the flow cross-section at the outlet is always a regular shape, thereby reducing the contact area with air and thus increasing the range of the water jet.

[0045] It should be noted that the inner diameters of the fixed ring 33 and the adjusting ring 32 are equal, and the outlet is the hole inside the fixed ring 33 and the adjusting ring 32. In this embodiment, a rotary drive is used as the power source to drive the adjusting ring 32 to rotate, so as to adjust the position of each stop 31. Using a rotary drive to drive a ring to rotate is existing technology, which can be directly applied and will not be described in detail.

[0046] Furthermore, each stop block 31 has a distribution cavity 313, and each stop block 31 has a hole array 314 communicating with the distribution cavity 313. Each stop block 31 has a water inlet hole 315 communicating with the distribution cavity 313. When each stop block 31 is driven to slide to the end of its stroke, the water inlet hole 315 connects the inner cavity of the gun body 21 with the distribution cavity 313.

[0047] Specifically, different irrigation methods are required for different objects. For example, trees need to be irrigated in a concentrated manner around the roots, which requires the water flow at the outlet to be columnar. However, since shrubs are continuous, it is impossible to directly irrigate the roots. Therefore, a rain-like spray is needed to ensure comprehensive irrigation. In this embodiment, each baffle 31 has a distribution cavity 313 and a hole array 314. The hole array 314 is located on the surface of the fixed ring 33 of the baffle 31 away from the adjusting ring 32. The hole array 314 consists of several small holes evenly distributed on the baffle 31, and each small hole is connected to the distribution cavity 313. In addition, each baffle 31 has a water inlet 315 connected to the distribution cavity 313. Optionally, the water inlet 315 is located on the surface of the adjusting ring 32 corresponding to each baffle 31, and each water inlet 315 is equipped with a solenoid valve.

[0048] When the water outlet mode needs to be adjusted to a rain-like pattern, first open the solenoid valves on each baffle 31 so that the inlet hole 315 connects the inner cavity of the straight pipe 212 with the distribution cavity 313. Some water enters the distribution cavity 313 through the inlet hole 315 and flows out through the orifice array 314. Then, the adjusting ring 32 drives each baffle 31 to move synchronously into the outlet, further reducing the flow cross section of the outlet until each baffle 31 slides to the end of its stroke. At this time, due to the limitation of the baffle 31 structure, the outlet cannot be completely blocked, and there is still a gap at the position of the outlet's central axis. However, most of the water will enter the distribution cavity 313 in each baffle 31 and spray out through the orifice array 314 to achieve rain-like irrigation.

[0049] Obviously, in order to avoid water leakage at the contact surface between the baffle 31 and the fixed ring 33, which would affect the formation of the rain shower water flow, each baffle 31 and the fixed ring 33 are dynamically sealed, and adjacent baffles 31 are also dynamically sealed. This is existing technology and can be directly applied without further explanation.

[0050] Furthermore, a support column 332 is coaxially arranged on the inner side of the fixing ring 33. The part of the side wall of the support column 332 that is directly opposite to the fixing ring 33 forms an annular protrusion 3321 along its own circumference. When each stop block 31 is driven to slide to the end of its stroke, the opening surface of the hole array 314 on each stop block 31 contacts the annular protrusion 3321.

[0051] Specifically, in the above embodiments, due to the limitations of the structure and sliding method of the baffle 31, each baffle 31 cannot completely block the outlet at the end of its stroke, and there is still a gap at the position of the central axis of the outlet. Furthermore, since the part of the baffle 31 corresponding to the central axis of the fixing ring 33 is not supported, the support of the water flow for a long time will cause the baffle 31 to deform. In this embodiment, a support column 332 is fixedly connected inside the straight pipe 212. The support column 332 is coaxially arranged with the outlet, i.e., the fixing ring 33. The support column 332 extends to the surface of the fixing ring 33 away from the baffle 31, and the end of the support column 332 is flush with the end face of the fixing ring 33. The outer wall has an annular protrusion 3321 along its circumference. When the baffle 31 is driven to slide to the end of its stroke (completely blocking the water outlet without considering the gap), the surface of each baffle 31 corresponding to the fixed ring 33 near the central axis of the fixed ring 33 is in contact with the annular protrusion 3321. Preferably, the baffle 31 and the annular protrusion 3321 are dynamically sealed together. This allows the support column 332 to support the baffle 31 while sealing the gap at the end of each baffle 31 when the baffle 31 is at the end of its stroke, so that all the water can enter the distribution cavity 313 and be sprayed outward in a rain-like manner.

[0052] In another embodiment of the present invention, the support column 332 is a cylindrical tube closed at one end. The side wall of the support column 332 is provided with a first through groove 3322 close to the closed end. A blocking member is provided on the support column 332. The blocking member has a first position and a second position along the axial direction of the support column 332. When it is in the first position, the blocking member blocks the first through groove 3322. When it is in the second position, the blocking member blocks the water inlet hole 315 on each block 31.

[0053] Specifically, in actual use, the water cannon 2 is not simply used for irrigation; it may also be used to wash and clean roads, guardrails, and billboards. This requires a high water flow rate to achieve the washing effect. This necessitates that the stop block 31 slide to a position near the end of its stroke, leaving a small annular hole between the stop block 31 and the support column 332 for water to flow out, ensuring sufficient water flow. This results in the support column 332 losing its supporting effect on the stop block 31 (the stop block 31 cannot contact the annular protrusion 3321 on the support column 332, otherwise water cannot flow out). Furthermore, the presence of the support column 332 also affects the formation of a strong water flow. In this embodiment, the support column 332 is a cylindrical tube closed at one end, and the end of the support column 332 facing the inside of the cannon body 21 is... Figure 6 The lower end is closed in the view, and a first through groove 3322 is provided on the side wall of the support column 332 at the position corresponding to the closed end, as shown. Figures 5 to 8As shown, the first through groove 3322 is arranged circumferentially along the side wall of the support column 332, connecting the inner cavity of the support column 332 with the space outside the support portion, so that water can enter the inner cavity of the support column 332 through the first through groove 3322 and flow outward from its opening; the support column 332 is also provided with a blocking member, which is a sleeve 34 fitted onto the outer wall of the support column 332. The sleeve 34 is driven to move along the axial direction of the support column 332, and the sleeve 34 can be restricted from rotating relative to the support column 332 by the cooperation of the locking block and the locking groove; the difference from the above embodiment is that, In this embodiment, the water inlet holes 315 on each stop block 31 are all opened on the arc-shaped surface of the stop block 31 near the central axis of the fixing ring 33. The sleeve 34 is provided with a second through groove 341 corresponding to the first through groove 3322. The number of the first through groove 3322 and the second through groove 341 are the same as the number of stop blocks 31 and are directly opposite each other. The second through groove 341 is evenly opened along the circumference of the sleeve 34, and the length of the second through groove 341 is equal to that of the first through groove 3322. The stop block 31 is adapted to the outer wall of the sleeve 34, that is, the diameter of the smaller arc-shaped surface on the stop block 31 is equal to the outer diameter of the sleeve 34.

[0054] The sleeve 34 has a first position and a second position during its stroke when it is driven to move axially along the support column 332:

[0055] When in the first position, the second through groove 341 and the first through groove 3322 are directly opposite each other, such as Figure 8 As shown, at this time, the outer wall of the sleeve 34 contacts the smaller arc-shaped surface on the baffle 31, and completely blocks the water outlet holes on each baffle 31. That is, at this time, the water flow can only enter the interior of the support column 332 through the second through groove 341 and the first through groove 3322, and exit through the opening of the support column 332. Preferably, the surfaces of the sleeve 34 and the baffle 31 that are in contact are dynamically sealed so that the baffle 31 can remain sealed when in contact with the outer wall of the sleeve 34, and the water flow cannot enter the distribution cavity 313 through the water inlet hole 315.

[0056] When in the second position, the second through groove 341 is completely offset from its corresponding first through groove 3322. Figure 8 The sleeve 34 in the view can be moved upward to adjust to the second position. At this time, the sleeve 34 and each stop 31 are offset along the axial direction of the fixed ring 33. That is, each water inlet 315 is not blocked. When the stop 31 is at the end of its stroke, the water can enter each distribution cavity 313 through the water inlet 315 and flow out through the hole array 314 opened on each stop 31.

[0057] It should be noted that since the contact surfaces of the stop 31 and the sleeve 34 are arc-shaped, and the stop 31 is adjusted by sliding, in actual operation, the stop 31 must first be slid to the end of its stroke before the sleeve 34 is moved to the first position. Otherwise, the sleeve 34 will block the sliding of the stop 31, causing the stop 31 to be unable to slide to the end of its stroke.

[0058] When it is necessary to dynamically adjust the columnar water flow, keep the sleeve 34 in the first position mentioned above and drive the adjusting ring 32 to rotate. At this time, the water can flow outward through the channel between each baffle and the outer wall of the support column 332, and can also enter the support column 332 through the second through groove 341 and the first through groove 3322, and flow out from the opening of the support column 332. As the position of the baffle changes, since the cross-sectional size of the inner cavity of the support column 332 is constant, while the size of the channel (the above-mentioned flow cross-section) between each baffle and the outer wall of the support column 332 is adjusted, the speed of water flow also changes accordingly.

[0059] When it is necessary to maintain a rain-like water flow, first adjust the sleeve 34 from the first position to the second position, and then drive the adjusting ring 32 to rotate. The adjusting ring 32 drives each stop block 31 to slide to the end of its stroke. At this time, the smaller arc surfaces on each stop block 31 together form a circle with a diameter equal to the outer diameter of the sleeve 34, driving the sleeve 34 to move along the axial direction of the support column 332. The outer wall of the sleeve 34 contacts the stop block 31. At this time, the water flow only enters each distribution cavity 313 through the water inlet hole 315 and flows outward from the hole array 314 opened on the stop block 31 to form a rain-like water flow.

[0060] When it is necessary to wash and clean the road surface, guardrail or billboard, first rotate the adjusting ring 32, adjust the stop block 31 to slide to the end of its stroke position, and then drive the sleeve 34 to move along the axial direction of the support column 332, adjusting the sleeve 34 from the second position to the first position. At this time, the water can only enter the interior of the support column 332 through the second through groove 341 and the first through groove 3322, and flow outward from the opening of the support column 332. Since the flow cross section is the smallest at this time, the water velocity is the largest when the flow rate is constant, which is suitable for washing.

[0061] In this embodiment, the position of the sleeve 34 along the axial direction of the support column 332 is adjusted. On the one hand, this ensures that only one of the water inlet hole 315 and the first through groove 3322 is always open, that is, the water flow either enters the distribution cavity 313 or the support column 332, which facilitates the switching of the water flow state. On the other hand, when the sleeve 34 is in the first position, the outer wall of the sleeve 34 contacts the small arc-shaped surface on the stop block 31. At this time, each stop block 31 can clamp the sleeve 34 from all directions, thereby improving the stability of both the sleeve 34 and the support column 332 and preventing the fixation of the support column 332 from being damaged by the high-speed water flow.

[0062] Furthermore, a push rod 26 is installed on the gun body 21 along the axial direction of the fixing ring 33. One end of the push rod 26 is rotatably connected to the sleeve 34, and the other end of the push rod 26 extends through to the outside of the gun body 21. The push rod 26 is dynamically sealed to the gun body 21.

[0063] Specifically, such as Figure 4 As shown, by setting a push rod 26 and making it dynamically sealed with the gun body 21, it is ensured that during the process of the push rod 26 pushing the sleeve 34 to move axially along the support column 332, the position on the gun body 21 where the push rod 26 protrudes will not leak water.

[0064] In another embodiment of the present invention, an adjusting rod 23 is fixedly connected to the gun body 21, and a handle 24 is installed at the end of the adjusting rod 23 away from the gun body 21. The setting of the adjusting rod 23 and the handle 24 makes it convenient for the operator to adjust the angle of the gun body 21.

[0065] Furthermore, a transmission mechanism 4 is also provided on the gun body 21, and an adjustment handle 25 is rotatably mounted on the handle 24. The adjustment handle 25 is connected to the adjustment ring 32 through the transmission mechanism 4.

[0066] Specifically, the transmission mechanism 4 includes a first shaft 41 rotatably mounted on the gun body 21. The first shaft 41 is arranged parallel to the straight pipe 212, and a spur gear 411 is fixedly connected to one end of the first shaft 41 corresponding to the water outlet. A spur gear ring 322 is fitted on the adjusting ring 32. Figure 3 , Figure 5 and Figure 7 As shown, a slot 333 is provided on the fixed ring 33 at the position corresponding to the spur gear 411. The spur gear 411 meshes with the spur ring 322. A second shaft 42 is rotatably mounted inside the adjusting rod 23. The first end of the first shaft 41 away from the spur gear 411 is connected to the second shaft 42 via a coupling 421. An adjusting handle 25 is rotatably mounted on the handle 24. The adjusting handle 25 and the handle 24 are respectively located on both sides of the end of the adjusting rod 23 away from the gun body 21. The adjusting handle 24 is connected to the second shaft 42 via a bevel gear set 422. Figure 11 As shown, the use of bevel gear set 422 to connect two mutually perpendicular shafts is an existing technology that can be directly applied and will not be elaborated further. A protective cover is provided on the straight tube 212 at the position corresponding to the first shaft 41, and the first shaft 41 and the spur gear 411 are both inside the protective cover.

[0067] Furthermore, the grip 24 is also equipped with a locking element 5 for locking the adjustment handle 25.

[0068] Specifically, in the above embodiments, when it is necessary to maintain a rain-like water flow or a high-speed water flow corresponding to rinsing, the baffle needs to remain stationary at the end of its stroke. That is, the adjustment handle 25 cannot be rotated in the reverse direction (it cannot be rotated further in the forward direction). However, since the operator needs to hold the handle 24 to adjust the angle of the gun body 21, the adjustment handle 25 may be accidentally rotated during this process, causing the position of the stop block 31 to be adjusted. In this embodiment, an elastic telescopic rod 51 is installed inside the handle 24. One end of the elastic telescopic rod 51 is threadedly connected to the handle 24, and the other end of the elastic telescopic rod 51 is rotatably connected to a first end face tooth 52. The adjustment handle 25 is fixedly connected to... The first end face tooth 52 and the second end face tooth 53 mesh with each other. When the elastic telescopic rod 51 is rotated and spiraled along the handle 24, when the elastic telescopic rod 51 is retracted to its shortest length, the second end face tooth 53 is locked by the first end face tooth 52, and the adjusting handle 25 cannot be rotated. When the elastic telescopic rod 51 is in the extended state, the adjusting handle 25 will push the first end face tooth 52 through the second end face tooth 53 during rotation, so that the first end face tooth 52 drives the elastic telescopic rod 51 to retract once and then return to its original position. This makes the rotation of the adjusting handle 25 have a certain resistance, further avoiding accidental rotation when adjusting the angle of the gun body 21.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
