It can be understood that the specific embodiments described herein are only used to explain the utility model and are not limited to the utility model. In addition, it should be noted that only the parts related to the utility model are shown in the drawings for ease of description, not all the structures.

[0031] In the description of the utility model, unless otherwise explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship of two elements.

[0033] In the description of the embodiment, the terms "up", "down", "right", etc. orientation or position relationship is based on the orientation or position relationship shown in the drawings, only for the convenience of description and simplification of operation, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the utility model. In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.

[0034] Referring to Figures 1 to 7 As shown in the drawings, the sprinkling irrigation gun provided by the embodiment of the present application comprises a base 100, a main pipe 200, a water spraying device 300, a horizontal driving assembly 400 and a transmission rod 500. The base 100 comprises a main seat 110 and a support 120 which are rotatably connected. The main seat 110 is provided with a gear disc and a communication cavity is defined in the base 100. The main pipe 200 is fixed on the support 120 and communicates with the communication cavity. The water spraying device 300 comprises a shunt module 310 and a plurality of water spraying pipes 320. The plurality of water spraying pipes 320 communicate with the main pipe 200 through the shunt module 310. The water outlet end of the water spraying pipe 320 is connected with a nozzle 600. The horizontal driving assembly 400 comprises a steering disc 410, a worm arranged on the steering disc 410, a steering nozzle 420 which communicates with the communication cavity and a reduction gearbox 430 which is drivingly connected with the worm. The inlet end of the steering nozzle 420 is movably connected with the support 120 and they communicate with each other. The outlet end of the steering nozzle 420 is arranged towards the steering disc 410. The water sprayed by the steering nozzle 420 can drive the steering disc 410 to rotate in the clockwise or counterclockwise direction. The steering disc 410 can drive the input end of the reduction gearbox 430 to rotate through the worm. One end of the transmission rod 500 is connected with the output end of the reduction gearbox 430. The other end of the transmission rod 500 passes through the support 120 and is provided with external teeth which mesh with the gear disc. The reduction gearbox 430 can drive the transmission rod 500 to rotate and the transmission rod 500 can rotate around the gear disc, so that the support 120 drives the main pipe 200 and the nozzle 600 to rotate in the horizontal direction relative to the main seat 110.

[0035] In addition, the outer peripheral wall of the main seat 110 is further provided with two limiting rods 111 which are arranged along the radial direction of the main seat 110. The two limiting rods 111 are arranged at an included angle. One side of the support 120 is provided with an oscillatable reversing element 121 which is in clamped engagement with the steering nozzle 420. The reversing element 121 is provided with a top rod 1211 and a connecting rod structure 1212. The top rod 1211 is located between the two limiting rods 111. The top rod 1211 can drive the reversing element 121 to oscillate through the connecting rod structure 1212. When the support 120 rotates, the reversing element 121 and the top rod 1211 rotate with the support 120. When the top rod 1211 contacts with the limiting rod 111, the support 120 continues to rotate. The top rod 1211 drives the reversing element 121 to oscillate through the connecting rod structure 1212. The reversing element 121 drives the steering nozzle 420 to oscillate, so as to change the angle of the steering nozzle 420 towards the steering disc 410, drive the steering disc 410 to rotate reversely and further drive the support 120 and the water spraying pipe 320 on the support 120 to rotate reversely, so as to realize the periodic self-rotation type water spraying of the water spraying pipe 320.

[0036] It can be understood that by setting the shunt module 310, the high-pressure water flow in the main pipe 200 is distributed to multiple water spray pipes 320 after passing through the shunt module 310, thereby increasing the water flow path. Under the premise that the water pressure remains high, the total flow of the multiple water spray pipes 320 increases compared to the flow of the existing single water spray pipe 320, and the flow of a single water spray pipe 320 in the multiple water spray pipes 320 is smaller than that of the existing single water spray pipe 320. The spray distance of the water spray pipe 320 is reduced. Combined with the shunt capability of the multiple water spray pipes 320, the crops near the sprinkler gun can be effectively covered, the spray effect of the gun is optimized, and sufficient water quantity is ensured.

[0037] Referring to Figure 1 and Figure 2 It can be understood that the shunt module 310 includes a pipe joint 311 and a water distribution assembly 312. The pipe joint 311 is connected to the water outlet end of the main pipe 200. The pipe joint 311 defines a water passing cavity 3111. The water passing cavity 3111 is open at an end away from the main pipe 200. The water distribution assembly 312 can be provided as a cover structure matching the shape of the opening. The water distribution assembly 312 is sealingly connected to the pipe joint 311 to close the opening of the water passing cavity 3111. Specifically, the water distribution assembly 312 is bolted to the pipe joint 311, and a sealing ring is provided at the connection between the water distribution assembly 312 and the pipe joint 311. The water distribution assembly 312 is provided with a plurality of water outlets 3121, which are in communication with the water spray pipes 320.

[0038] By providing the pipe joint 311 and the water distribution assembly 312, the structure of the shunt module 310 can be simplified, and the shunt module 310 can be easily assembled and used. By replacing different water distribution assemblies 312, the number of water outlets 3121 connected to the pipe joint 311 can be changed, thereby changing the number of water spray pipes 320 and effectively improving the modularization degree of the water spraying device 300.

[0039] Referring to Figure 1 , Figure 2 and Figure 5 It can be understood that the first connecting portion is provided on one end of the water spray pipe 320 close to the base 100, and the second connecting portion 3122 is provided on the side of the water distribution assembly 312 away from the pipe joint 311. The first connecting portion and the second connecting portion 3122 are detachably connected. Alternatively, the first connecting portion and the second connecting portion 3122 can be a matching internal and external thread structure, a clamping groove and hole structure, a lock and slot structure, etc., which will not be described here.

[0040] By providing the first connecting portion and the second connecting portion 3122, the user can conveniently assemble and disassemble the water spray pipe 320 and the water distribution assembly 312, thereby facilitating the user to overhaul, maintain or replace the water spray pipe 320 and the water distribution assembly 312, improving the assembly and disassembly convenience of the water spray pipe 320, and further improving the modularization degree of the water spraying device 300.

[0041] In some crop sprinkler irrigation scenarios where flow rates need to be frequently adjusted, the spray nozzle 3121 is directly connected to the water passage chamber 3111. Users cannot directly adjust the water output of the nozzle; instead, they indirectly adjust the output by controlling the nozzle's rotation speed and rotation period. However, this adjustment method is cumbersome, and the actual adjustment results are affected by various factors such as transmission efficiency and mechanical wear, making it difficult to achieve the ideal water output effect and easily leading to problems such as insufficient water output or water waste.

[0042] Reference Figure 1 , Figure 3 and Figure 4 As shown ( Figure 3 The black filler indicates that through hole 3132 is not connected to outlet hole 3121. Figure 3 (The structure related to the positioning component 315 has been omitted.) It can be understood that the water distribution component 312 includes a fixed plate 313 and a rotating plate 314. The fixed plate 313 is provided with multiple water control structures 3131, which are spaced apart along the circumference of the fixed plate 313. Each water control structure 3131 includes several through holes 3132 and several water-blocking parts 3133. The water-blocking parts 3133 are the solid structures on the fixed plate 313 without holes. The through holes 3132 and the water-blocking parts 3133 are arranged sequentially along the X direction. That is, the through holes 3132 are spaced apart along the X direction on the circumference of the fixed plate 313, and the water-blocking parts 3133 are also spaced apart along the X direction on the circumference of the fixed plate 313. Furthermore, the water-blocking parts 3133 are located at the rear end of the through holes 3132 in the X direction.

[0043] Along the X direction, the number of through holes 3132 in the multiple water control structures 3131 decreases sequentially, with the X direction being either clockwise or counterclockwise. Specifically, the sequential decrease in the number of through holes 3132 in the water control structures 3131 along a clockwise (or counterclockwise) direction is equivalent to the sequential increase in the number of through holes 3132 in the water control structures 3131 along a counterclockwise (or clockwise) direction.

[0044] It should be noted that the total number of through holes 3132 and water blocking portions 3133 in each water control structure 3131 can be equal to or different from the number of water control structures 3131. When the total number of through holes 3132 and water blocking portions 3133 in the water control structure 3131 is equal to the number of water control structures 3131, the number of through holes 3132 in the first water control structure 3131 is equal to the number of water control structures 3131. Under this premise, the number of through holes 3132 in the water control structure 3131 decreases in turn, that is, along the X direction, the number of through holes 3132 in the water control structure 3131 located at the rear is one less than the number of through holes 3132 in the water control structure 3131 located at the front (not considering the number difference of through holes 3132 between the water control structure 3131 with only one through hole 3132 at the end in the X direction and the water control structure 3131 without water blocking portion 3133 at the beginning), and the number of through holes 3132 in the water control structure 3131 is reduced to one at least.

[0045] Exemplarily, when two water control structures 3131 are provided, one of the water control structures 3131 includes two through holes 3132, and the other water control structure 3131 includes one through hole 3132 and one water blocking portion 3133. When four water control structures 3131 are provided, one of the water control structures 3131 includes four through holes 3132, and the three water control structures 3131 located at the rear end of the water control structure 3131 in the X direction in turn include three through holes 3132, two through holes 3132 and one through hole 3132, starting from the water control structure 3131.

[0046] The above arrangement can be further described by a mathematical model, which is specifically described as follows:

[0047] The fixed disc 313 is provided with n water control structures 3131, each water control structure 3131 includes a through hole 3132 and b water blocking portions 3133, which satisfy: a+b=n, and a≥1. The n water control structures 3131 are arranged at intervals along the circumference of the fixed disc 313. The a and n in one of the water control structures 3131 satisfy: a=n, and the water control structure 3131 is defined as a set A0, which satisfies: {A0|a=n, b=0}. Starting from A0 in the X direction, the subsequent xth water control structure 3131 is defined as Ax, which satisfies: {Ax|a=n-x, b=x}, where 1≤x≤n-1. x x x |a=n-x, b=x}, where 1≤x≤n-1.

[0048] When the total number of the through holes 3132 and the water blocking portions 3133 in the water control structure 3131 is not equal to the number of the water control structures 3131, with the decrease of the number of the through holes 3132 in the water control structure 3131, the total number of the through holes 3132 and the water blocking portions 3133 determines the number of the through holes 3132 in the last water control structure 3131. When the total number of the through holes 3132 and the water blocking portions 3133 in the water control structure 3131 is less than the number of the water control structures 3131, there is no through hole 3132 in the last water control structure 3131 along the X direction, and when the total number of the through holes 3132 and the water blocking portions 3133 in the water control structure 3131 is greater than the number of the water control structures 3131, there is at least one through hole 3132 in the last water control structure 3131.

[0049] Exemplarily, when the water control structure 3131 is provided with three, and the total number of the through holes 3132 and the water blocking portions 3133 in each water control structure 3131 is two, along the X direction, the first water control structure 3131 includes two through holes 3132, the middle water control structure 3131 includes one through hole 3132 and one water blocking portion 3133, and the last water control structure 3131 includes two water blocking portions 3133 (i.e. the fixed disc 313 has no through hole 3132 structure at the last water control structure 3131). When the water control structure 3131 is provided with three, and the total number of the through holes 3132 and the water blocking portions 3133 in each water control structure 3131 is four, along the X direction, the first water control structure 3131 includes three through holes 3132 and one water blocking portion 3133, the middle water control structure 3131 includes two through holes 3132 and two water blocking portions 3133, and the last water control structure 3131 includes one through hole 3132 and three water blocking portions 3133.

[0050] The above arrangement can be further described by a mathematical model, which is specifically described as follows:

[0051] The fixed disc 313 is provided with n water control structures 3131, the n water control structures 3131 are arranged at intervals along the circumference of the fixed disc 313, each water control structure 3131 includes a through hole 3132 and b water blocking portions 3133, and satisfies: a+b=m. When m y y ​|a = m - y, b = y}, where 1≤y≤m. When m>n, one of a and n in one water control structure 3131 satisfies: a = n, and the water control structure 3131 is defined as a set Co, satisfying {Co | a = n, b = m - n}. Starting from Co in the X direction, the subsequent z-th water control structure 3131 is defined as Cz, satisfying {Cz | a = n - z, b = m - n + z}, where 1≤z≤n-1. z , satisfying {C z |a = n - z, b = m - n + z}, where 1≤z≤n-1.

[0052] The number of water control structures 3131 and the total number of through holes 3132 and water blocking portions 3133 in each water control structure 3131 are not specifically limited herein, and the user can set appropriate numbers of water control structures 3131 and the total number of through holes 3132 and water blocking portions 3133 in each water control structure 3131 according to actual needs, as long as the water spraying amount meets the needs of crops.

[0053] The rotating disc 314 is coaxially arranged with the fixed disc 313, and is tightly attached to and rotationally connected with the fixed disc 313. The rotating disc 314 is provided with a plurality of water outlets 3121. The water outlets 3121 are one-to-one correspondingly arranged with the water control structures 3131 and can be correspondingly communicated with the through holes 3132 in the water control structures 3131. The water spraying pipe 320 is communicated with the through holes 3132 through the water outlets 3121. When the total number of through holes 3132 and water blocking portions 3133 in the water control structure 3131 is less than the number of water control structures 3131, and the water control structure 3131 located at the end in the X direction does not have a through hole 3132, the water outlet 3121 corresponding to the water control structure 3131 located at the end does not spray water. It is particularly stated herein to avoid misunderstanding.

[0054] Rotating the rotating disc 314 in the X direction can gradually reduce the number of water outlets 3121 communicated with the through holes 3132 (when the number of water outlets 3121 communicated with the through holes 3132 is reduced to a minimum value, and the rotating disc 314 is continuously rotated in the X direction, the rotating disc 314 will reset to the initial state where the number of water outlets 3121 communicated with the through holes 3132 is the maximum). Similarly, rotating the rotating disc 314 in the reverse direction of the X direction can gradually increase the number of water outlets 3121 communicated with the through holes 3132.

[0055] It should be noted that the distribution of the corresponding through holes 3132 (or water blocking portions 3133) in the plurality of water control structures 3131 is the same as the distribution of the plurality of water outlets 3121, and the arrangement of the adjacent two through holes 3132 in the same water control structure 3131 can be set according to actual needs. For example, when the water control structure 3131 is provided with three, and the total number of through holes 3132 and water blocking portions 3133 in each water control structure 3131 is also three, the water outlet 3121 is provided with three corresponding to the water control structure 3131, and the included angle between the adjacent two water outlets 3121 (i.e. the central angle between the adjacent two water outlets 3121 and the center of the rotating disc 314) is 120°. Then, the three through holes 3132 located in the first position in the X direction in the three water control structures 3131 are also distributed in the form of an included angle of 120° between two, the two through holes 3132 and one water blocking portion 3133 located in the second position in the X direction in the three water control structures 3131 are also distributed in the form of an included angle of 120° between two, and the one through hole 3132 and two water blocking portions 3133 located in the third position in the X direction in the three water control structures 3131 are also distributed in the form of an included angle of 120° between two, but the included angle between the adjacent two through holes 3132 (or the adjacent through hole 3132 and the water blocking portion 3133, or the adjacent two water blocking portions 3133) in the same water control structure 3131 can be set according to actual needs. Hereinafter, the adjacent two through holes 3132 in the same water control structure 3131 are described to be distributed at equal intervals, and it is particularly stated here to avoid misunderstanding.

[0056] It can be understood that the water control structure 3131 is provided with the rotating disc 314 and the fixed disc 313, the user rotates the rotating disc 314 along the X direction, the water outlet 3121 rotates with the rotating disc 314 and moves relative to the water control structure 3131, and since the number of through holes 3132 in the water control structure 3131 decreases in turn along the X direction, the water outlet 3121 located at the rear end in the X direction moves to the water blocking portion 3133 (or the through hole 3132) located at the rear end in the X direction in the corresponding water control structure 3131 every time the rotating disc 314 rotates by a certain angle (i.e. the included angle between the adjacent two through holes 3132 in the same water control structure 3131). At this time, the number of water outlets 3121 corresponding to the through holes 3132 is correspondingly reduced, achieving the purpose of reducing the water flow.

[0057] Exemplarily, when the water control structures 3131 are provided with three, the total number of the through holes 3132 and the water blocking portions 3133 in each water control structure 3131 is also three, and the three water control structures 3131 are equidistantly arranged, and the through holes 3132 and the water blocking portions 3133 in the same water control structure 3131 are also equidistantly arranged (i.e. the included angle between two adjacent water control structures 3131 is 120°, and the included angle between two adjacent through holes 3132 and water blocking portions 3133 in each water control structure 3131 is 30°), the water outlet holes 3121 are correspondingly provided with three water control structures 3131. In the initial state, the three water outlet holes 3121 are communicated with the three through holes 3132 located at the front in the X direction (the clockwise direction of the side of the rotating disc 314 away from the fixed disc 313 is defined as the X direction) in the corresponding water control structures 3131. The rotating disc 314 rotates clockwise by 30°, at this time, in the X direction, the water outlet hole 3121 located at the end is rotated to the water blocking portion 3133 located in the middle in the corresponding water control structure 3131, and the other two water outlet holes 3121 are rotated to the through holes 3132 located in the middle in the corresponding water control structures 3131, in this state, only two water outlet holes 3121 are communicated with the main pipe 200. The rotating disc 314 continues to rotate clockwise by 30°, at this time, in the X direction, the water outlet hole 3121 located at the front is rotated to the through hole 3132 located at the end in the corresponding water control structure 3131, and the other two water outlet holes 3121 are rotated to the water blocking portions 3133 located at the end in the corresponding water control structures 3131, in this state, only one water outlet hole 3121 is communicated with the main pipe 200.

[0058] Exemplarily, when the water control structures 3131 are provided with three, the total number of the through holes 3132 and the water blocking portions 3133 in each water control structure 3131 is also three, and the three water control structures 3131 are equidistantly arranged, and the through holes 3132 and the water blocking portions 3133 in the same water control structure 3131 are also equidistantly arranged (i.e. the included angle between two adjacent water control structures 3131 is 120°, and the included angle between two adjacent through holes 3132 and water blocking portions 3133 in each water control structure 3131 is 60°), the water outlet holes 3121 are correspondingly provided with three water control structures 3131. In the initial state, the two water outlet holes 3121 located at the front in the X direction are correspondingly communicated with the two through holes 3132 located at the front in the X direction in the corresponding water control structures 3131. The rotating disc 314 rotates clockwise by 60°, at this time, in the X direction, the two water outlet holes 3121 located at the back are rotated to the water blocking portions 3133 located at the second position in the corresponding water control structures 3131, and the water outlet hole 3121 located at the front is rotated to the through hole 3132 located at the second position in the corresponding water control structure 3131, in this state, only one water outlet hole 3121 is communicated with the main pipe 200. The rotating disc 314 continues to rotate clockwise by 60°, at this time, the rotating disc 314 returns to the initial state that the two water outlet holes 3121 are correspondingly communicated with the two through holes 3132.

[0059] Exemplarily, when the three water control structures 3131 are provided, the total number of the through holes 3132 and the water blocking portions 3133 in each water control structure 3131 is four, the three water control structures 3131 are equidistantly arranged, and the through holes 3132 and the water blocking portions 3133 in the same water control structure 3131 are also equidistantly arranged (i.e., the included angle between two adjacent water control structures 3131 is 120°, and the included angle between two adjacent through holes 3132 and water blocking portions 3133 in each water control structure 3131 is 22.5°), the water outlet hole 3121 is correspondingly provided with three water control structures 3131. In the initial state, the three water outlet holes 3121 are communicated with the three through holes 3132 located at the first position in the X direction in the corresponding water control structure 3131. When the rotating disc 314 rotates clockwise by 22.5°, in the X direction, the water outlet hole 3121 located at the end is rotated to the water blocking portion 3133 located at the second position in the corresponding water control structure 3131, and the other two water outlet holes 3121 are rotated to the through holes 3132 located at the second position in the corresponding water control structure 3131. In this state, only two water outlet holes 3121 are communicated with the main pipe 200. When the rotating disc 314 continues to rotate clockwise by 22.5°, in the X direction, the water outlet hole 3121 located at the first position is rotated to the through hole 3132 located at the third position in the corresponding water control structure 3131, and the other two water outlet holes 3121 are rotated to the water blocking portions 3133 located at the third position in the corresponding water control structure 3131. In this state, only one water outlet hole 3121 is communicated with the main pipe 200. When the rotating disc 314 continues to rotate clockwise by 22.5°, in the X direction, the three water outlet holes 3121 on the rotating disc 314 are all rotated to the water blocking portions 3133 located at the end in the corresponding water control structure 3131. In this state, the three water outlet holes 3121 are all disconnected with the main pipe 200, and the water spraying pipe 320 does not spray water.

[0060] According to the number of the water outlet holes 3121 on the rotating disc 314 communicated with the through holes 3132, different water outlet gears of the water spraying pipe 320 can be set. The greater the number of the water outlet holes 3121 on the rotating disc 314 communicated with the through holes 3132, the higher the different water outlet gears of the water spraying pipe 320. The user can switch different gears by rotating the rotating disc 314 to adjust the water output of the water spraying pipe 320. As known from the above embodiment, the total number of the through holes 3132 and the water blocking portions 3133 in each water control structure 3131 is the number of the water outlet gears of the water output of the water spraying pipe 320. When the total number of the through holes 3132 and the water blocking portions 3133 in each water control structure 3131 is less than or equal to the number of the water control structures 3131, the water spraying pipe 320 can quickly reset and spray water at any water outlet gear. When the total number of the through holes 3132 and the water blocking portions 3133 in each water control structure 3131 is greater than the number of the water control structures 3131, the water spraying pipe 320 stops spraying water at the lowest water outlet gear, which is convenient for the user to move the sprinkling irrigation lance.

[0061] The rotating disc 314 and the fixed disc 313 are simple in structure and convenient to operate. A user can set the number of the water control structures 3131 according to requirements, and quickly and accurately adjust the water output or even stop the water output through rotating the rotating disc 314, so as to adapt to crops with different water output requirements, avoid problems such as insufficient water output or waste of water resources, and directly rotate the rotating disc 314 to stop the water output without returning to the water source to close the water pump, the water valve or other water output components, thereby effectively improving the practicability and control accuracy of the sprinkling irrigation gun.

[0062] Further, the water distribution assembly 312 further comprises a screw 740, the center of the fixed disc 313 is provided with a screw hole 3137, the center of the rotating disc 314 is provided with a guide hole 3143, and the screw 740 is arranged in the guide hole 3143 and connected to the screw hole 3137. At this time, the rotating disc 314 rotates around the screw 740 as a fulcrum.

[0063] By arranging the screw 740, the rotating disc 314 is rotatably installed on the fixed disc 313, which simplifies the installation structure of the rotating disc 314 and effectively improves the convenience of dismounting and mounting the rotating disc 314, thereby facilitating subsequent maintenance, maintenance or replacement of the fixed disc 313 and the rotating disc 314.

[0064] Further, the outer peripheral wall of the fixed disc 313 is flush with the outer peripheral wall of the rotating disc 314, and the outer diameter of the fixed disc 313 is equal to the outer diameter of the rotating disc 314.

[0065] The outer peripheral wall of the fixed disc 313 is flush with the outer peripheral wall of the rotating disc 314, which facilitates positioning and installation of the rotating disc 314 and ensures that the multi-nozzle gun has a simple and natural appearance, thereby effectively improving the appearance of the multi-nozzle gun.

[0066] Referring to Figure 3 It can be understood that the water distribution assembly 312 further comprises a positioning assembly 315 located between the fixed disc 313 and the rotating disc 314 to position the rotating disc 314 in the X direction. Alternatively, the positioning assembly 315 can be arranged as a simple convex point and groove structure, a top wire and sliding groove structure, or a complex inductive sheet and photoelectric sensor assembly, which will not be described here.

[0067] By arranging the positioning assembly 315, the user can be prompted by the positioning assembly 315 whether the rotating disc 314 is rotated in place every time the rotating disc 314 is rotated, thereby ensuring that the water outlet holes 3121 on the rotating disc 314 are accurately aligned with the through holes 3132 on the fixed disc 313 before and after the rotating disc 314 is rotated, avoiding problems such as water leakage from the water outlet holes 3121 that should be turned off, abnormal water output from the water outlet holes 3121 that should be turned on, and the like, thereby further improving the control accuracy of the sprinkling irrigation gun and improving the user experience.

[0068] Furthermore, the water distribution assembly 312 also includes a sealing assembly 316, which abuts against the fixed plate 313 and the rotating plate 314. The seal can be an O-ring, oil seal, labyrinth structure, etc., which will not be elaborated here. By setting the seal, leakage between the rotating plate 314 and the fixed plate 313 is prevented when the rotating plate 314 rotates, effectively improving the sealing performance between the rotating plate 314 and the fixed plate 313.

[0069] Reference Figure 2 and Figure 5 As shown, it can be understood that the positioning component 315 includes a steel ball 3151 and a spring 3152, and the fixing plate 313 is provided with an arc-shaped positioning groove 3134. The central angle of the arc-shaped positioning groove 3134 is equal to the included angle between the two through holes 3132 at both ends of any water control structure 3131 (or between the through hole 3132 and the water blocking part 3133).

[0070] The positioning groove 3134 is provided with multiple positioning holes 3135 that match the shape of the steel ball 3151. The number of positioning holes 3135 is equal to the number of water control structures 3131. The multiple positioning holes 3135 are spaced apart along the X direction, and the central angle between two adjacent positioning holes 3135 and the center of the fixed plate 313 is the same as the central angle between two adjacent through holes 3132 in the same water control structure 3131 and the center of the fixed plate 313. The steel ball 3151 is located between the fixed plate 313 and the turntable 314 and is rolled and assembled in the positioning groove 3134. The spring 3152 is installed on the turntable 314 and abuts against the steel ball 3151.

[0071] As the user rotates the turntable 314, the spring 3152 drives the steel ball 3151 to roll in the positioning groove 3134. When the turntable 314 rotates a predetermined angle (i.e., the angle between two adjacent through holes 3132 in the same water control structure 3131), the steel ball 3151 also moves from one positioning cavity 3135 to another positioning cavity 3135. At this time, the steel ball 3151 is engaged in the positioning cavity 3135 under the action of the spring 3152, reminding the user that the turntable 314 has been rotated into place. By setting the positioning component 315 as a steel ball 3151 and a spring 3152, on the one hand, the structure of the spring 3152 and the steel ball 3151 is relatively simple, which can simplify the structure of the positioning component 315 and facilitate its assembly; on the other hand, the steel ball 3151 rolls in the positioning groove 3134, and the friction it experiences is small, resulting in less wear on the steel ball 3151, which can effectively extend the service life of the positioning component 315.

[0072] It should be noted that the rotating disc 314 is provided with a mounting hole 3141 penetrating the rotating disc 314, and the side of the rotating disc 314 away from the fixed disc 313 is provided with a detachable plug 3142 for closing the mounting hole 3141. Alternatively, the plug 3142 can be a screw threadedly connected with the mounting hole 3141 or a pin shaft insertedly matched with the screw hole 3137, which will not be described herein. The spring 3152 is limited in the mounting hole 3141 and abuts against the plug 3142.

[0073] By providing the detachable plug 3142, the user can detach the spring 3152 and the steel ball 3151 from the plug 3142 without detaching the entire rotating disc 314, further improving the convenience of assembling and disassembling the positioning assembly 315.

[0074] Further, the sealing assembly 316 includes a plurality of sealing rings, the sealing rings are provided one by one corresponding to the through holes 3132, and the side of the fixed disc 313 facing the rotating disc 314 is provided with a plurality of annular positioning grooves 3134, the positioning grooves 3134 are provided one by one corresponding to the through holes 3132 and surround the through holes 3132, and the sealing rings are limited in the positioning grooves 3134.

[0075] The sealing assembly 316 is provided as a plurality of sealing rings, which simplifies the structure of the sealing assembly 316 while increasing the independence between different through holes 3132, further improving the sealing between the rotating disc 314 and the fixed disc 313. In addition, the sealing rings are installed in the positioning grooves 3134, which can effectively improve the installation stability of the sealing rings.

[0076] Referring to Figure 6 It can be understood that the inner diameter of the nozzle 600 gradually decreases along the direction of the water flow in the water spraying pipe 320, the nozzle 600 is provided one by one corresponding to the water spraying pipe 320, and the nozzle 600 includes a base 610, a nozzle 600 body and a fixing sleeve 630, the base 610 is fixedly provided on the water spraying pipe 320, the nozzle 600 body is assembled on the base 610 through a hollow ball joint and can rotate upward or downward relative to the base 610, and the fixing sleeve 630 is detachably fixed on the base 610 and can seal and fixedly connect the nozzle 600 body and the base 610. The user can adjust the orientation of the nozzle 600 to control the water outlet direction and water outlet angle of the water spraying pipe 320, further improving the practicability of the multi-nozzle spray gun.

[0077] Referring to Figure 1 and Figure 6As shown, it can be understood that the water spraying pipe 320 is connected with a water breaker 700 at the end away from the shunt module 310, and the water breaker 700 and the nozzle 600 cooperate to disperse the water flow in the water spraying pipe 320. Specifically, in the embodiment, the water breaker 700 includes a fixing frame 710 and a top pin 730, the end of the top pin 730 is tapered, the fixing frame 710 is installed at the end of the water spraying pipe 320 away from the rotating disc 314 and located at one side of the nozzle 600, the fixing frame 710 is provided with a rotatable swing arm 720, and the top pin 730 is installed at the free end of the swing arm 720.

[0078] By setting the water breaker 700, the user can insert the tapered end of the top pin 730 into the nozzle 600 by rotating the swing arm 720, so as to reduce the water outlet area of the nozzle 600, disperse the water flow sprayed by the nozzle 600, and achieve the atomization effect. Thus, the sprinkling range of the multi-nozzle spraying gun is expanded, and the sprinkling effect of the nozzle 600 is optimized.
