Water-breaking nails, water-breaking rods, or no water-breaking device can be used in conjunction with the first nozzle 91, the second nozzle 92, and the third nozzle 92. The first water distribution sleeve valve 101 is used to open and close the first water distribution sleeve, the second water distribution sleeve valve 102 is used to open and close the second water distribution sleeve, and the third water distribution sleeve valve 103 is used to open and close the third water distribution sleeve. In this invention, taking the first nozzle as an example, two auxiliary nozzles 911 are also provided next to the first nozzle 91. Each auxiliary nozzle is equipped with a corresponding auxiliary nozzle water-breaking pin 912 and an on / off valve 913. Both the first nozzle 91 and the auxiliary nozzles 911 are connected to the first connecting pipe 111. Two auxiliary nozzles, auxiliary nozzle water-breaking pins, and on / off valves are provided next to the second nozzle 92, identical to those of the first nozzle. Similarly, two auxiliary nozzles, auxiliary nozzle water-breaking pins, and on / off valves are provided next to the third nozzle 93.

[0022] This utility model of a multi-mode rotary water sprayer mainly includes a main water pipe 1, a branch water pipe, multiple nozzles, a water-breaking mechanism, and a valve control system. These components work together to achieve switching between multiple irrigation modes.

[0023] The main water pipe 1 serves as the primary water flow channel, with one end connected to the base 2 via a connecting elbow 3, and the other end connected to the main distribution sleeve 10 of the distribution pipe. The base 2 has an inlet, which is the starting point for water flow into the spray gun. The base 2 is designed to be fixed to a frame or other sturdy object to ensure the stability of the spray gun during operation.

[0024] The water distribution pipe system includes a main water distribution sleeve 10, a first water distribution sleeve 11, a second water distribution sleeve 12, and a third water distribution sleeve 13. Each water distribution sleeve is connected to a corresponding connecting pipe via a valve to achieve water flow distribution and control.

[0025] The main water distribution sleeve 10, as the main body of the water distribution pipe, is connected to the main water pipe 1 and is responsible for introducing water flow into each water distribution sleeve. The first water distribution sleeve 11 is connected to the first connecting pipe 111 through the first water distribution sleeve valve 101 and the first rear connecting pipe 1102. The first connecting pipe 111 is then connected to the first nozzle 91. The second water distribution sleeve 12 and the third water distribution sleeve 13 have similar structures to the first water distribution sleeve 11, and are respectively connected to the corresponding connecting pipe and nozzle through their respective valves and rear connecting pipes.

[0026] The first nozzle 91 is connected to the first connecting pipe 111, and two auxiliary nozzles 911 are provided on the side. Each auxiliary nozzle is equipped with an auxiliary nozzle water breaker pin 912 and a switch valve 913. The second nozzle 92 and the third nozzle 93 have similar structures to the first nozzle 91, and are all equipped with auxiliary nozzles, auxiliary nozzle water breaker pins, and switch valves.

[0027] Also used in conjunction are the first water distribution sleeve valve 101, the second water distribution sleeve valve 102, the third water distribution sleeve valve 103, and the on / off valves 913 for each auxiliary nozzle, which are used to control the opening and closing of each nozzle and realize the switching of multiple working modes.

[0028] In this invention, the opening and closing of the first nozzle 91, the second nozzle 92, and the third nozzle 93 are controlled by switching the first water distribution sleeve valve 101, the second water distribution sleeve valve 102, and the third water distribution sleeve valve 103, thereby enabling the individual use of the first nozzle 91, the second nozzle 92, and the third nozzle 93; the combined use of the first nozzle 91 and the second nozzle 92; the combined use of the first nozzle 91 and the third nozzle 93; the combined use of the second nozzle 92 and the third nozzle 93; and the combined use of the first nozzle 91, the second nozzle 92, and the third nozzle 93.

[0029] The operation of this utility model is as follows: After the base 2 is pumped with water, the water flows into the main water pipe 1 through the connecting elbow 3. Subsequently, the water flows through the main water pipe 1 into the main distribution sleeve 10 of the distribution pipe, and is distributed through the first distribution sleeve 11, the second distribution sleeve 12, and the third distribution sleeve 13 respectively. During this process, the water flow into the first nozzle 91, the second nozzle 92, or the third nozzle 93 can be controlled by opening or closing the first distribution sleeve valve 101, the second distribution sleeve valve 102, or the third distribution sleeve valve 103. At the same time, the water flow into the auxiliary nozzles can be controlled by opening or closing the switch valves of each auxiliary nozzle, achieving more precise irrigation control. After the base 2 is pumped with water, in addition to the above-mentioned water distribution process, the water also enters the reversing nozzle 5. The water then sprays out from the reversing nozzle 5, driving the reversing impeller 6 to rotate. The rotation of the reversing impeller 6 drives the reversing transmission mechanism 7, which in turn drives the entire water spray gun (especially the water distribution pipe) to rotate, thereby expanding the irrigation range. When it rotates to a certain extreme position, it triggers the reversing nozzle actuation mechanism 8, which in turn actuates the reversing nozzle 5 to change the spray direction aligned with the reversing impeller, thus driving the reversing impeller 6 to rotate in the opposite direction, realizing the reciprocating rotation of the water spray gun. For a detailed explanation of this part, please refer to CN213194177U.

[0030] When water is pumped into the base 2 by the water pump, the water also enters the main water pipe 1 through the connecting elbow 3 and the reversing nozzle 5. The water then sprays out from the reversing nozzle 5, driving the reversing impeller 6 to rotate. The rotation of the reversing impeller 6 drives the reversing transmission mechanism 7.

[0031] Figure 1 The overall appearance of this multi-mode rotary water gun is shown. As can be seen from the image, the main water pipe 1 extends vertically downwards and connects to the base 2 via a connecting elbow 3. The branch water pipes can be controlled via external valves. The nozzle system is located at the front of the water gun for easy adjustment of the spray direction.

[0032] Figure 2 This shows the appearance of the water gun from another angle. (And...) Figure 1 compared to, Figure 2 The layout of the nozzle system is shown. It can be seen that each nozzle is connected to the connecting pipe via a rotary joint, enabling adjustment of the spray direction.

[0033] Figure 3 The structure of the water distribution pipe is shown in detail. The water distribution pipe consists of a main water distribution sleeve 10, a first water distribution sleeve 11, a second water distribution sleeve 12, and a third water distribution sleeve 13. Each water distribution sleeve is connected to its corresponding downstream pipe via a valve to achieve water flow distribution and control. The main water distribution sleeve 10 serves as the main channel for water flow and is connected to the main water pipe 1.

[0034] Figure 4This is a cross-sectional view of the main view of this utility model, which shows in detail the internal structure of the water spray gun. The view shows the connection method between the main water pipe 1 and the main water distribution sleeve 10, the connection method between the water distribution sleeve and the rear connecting pipe, and the transmission method of the water-breaking mechanism.

[0035] Figure 5 The diagram shows a partial structure including the third nozzle 93. As can be seen from the diagram, the third nozzle 93 is connected to the third water distribution sleeve 13 via a third connecting pipe, and two auxiliary nozzles, corresponding water-breaking pins, and switching valves are located alongside it. The third water-breaking pin 431 works in conjunction with the third nozzle 93 to achieve the water-breaking function.

[0036] In this utility model's water distribution pipe, water first enters the water spray gun system through the inlet of the base 2. The base 2 serves as the support and water inlet for the entire system, and its internal design ensures that the water can enter the main water pipe 1 smoothly and efficiently. The main water pipe 1, as the main channel for water flow, guides the water flow to the main distribution sleeve 10 of the distribution pipe.

[0037] The main water distribution sleeve 10 serves as the water distribution system, responsible for distributing water flow to the first water distribution sleeve 11, the second water distribution sleeve 12, and the third water distribution sleeve 13 as needed. Each water distribution sleeve is equipped with an independent valve (first water distribution sleeve valve 101, second water distribution sleeve valve 102, and third water distribution sleeve valve 103), which controls the flow of water by opening and closing the valves.

[0038] The first water distribution sleeve 11 controls the flow of water through the first water distribution sleeve valve 101. When the valve is open, water flows from the main water distribution sleeve 10 into the first water distribution sleeve 11, then through the first downstream pipe 1102 and the first connecting pipe 111, and finally reaches the first nozzle 91.

[0039] The working principle of the second water distribution sleeve 12 is similar to that of the first water distribution sleeve 11. Water flows from the main water distribution sleeve 10 into the second water distribution sleeve 12 under the control of the valve 102 of the second water distribution sleeve, and then through the second rear pipe and the second connecting pipe 121 to reach the second nozzle 92.

[0040] Similarly, the water flow is controlled by the valve 103 of the third water distribution sleeve, flowing from the main water distribution sleeve 10 into the third water distribution sleeve 13, and then through the third rear pipe and the third connecting pipe 131 to reach the third nozzle 93.

[0041] Valve control and operating mode switching are as follows:

[0042] Independent control. Each water distribution sleeve valve can be opened or closed independently, thus enabling the independent operation of a single nozzle. For example, when only the first nozzle 91 needs to operate, simply open the first water distribution sleeve valve 101 and close the second and third water distribution sleeve valves.

[0043] Combined control. By simultaneously opening multiple water distribution sleeve valves, multiple nozzles can operate in combination. For example, opening the first and second water distribution sleeve valves simultaneously allows the first and second nozzles to work at the same time, meeting irrigation needs over a wider area.

[0044] Full-open mode. When all the water distribution sleeve valves are open, the three nozzles will work simultaneously, forming the maximum irrigation range and flow rate, suitable for scenarios requiring large-area, high-power water spraying.

[0045] The advantage of multi-mode operation lies in its ability to achieve seven different operating modes (using each nozzle individually, using them in pairs, and using all three nozzles simultaneously) through an independent valve control system. This versatility allows the water gun to adapt to various irrigation scenarios and needs, enabling both small-scale precision irrigation and large-scale powerful spraying with a single water gun.

[0046] This utility model of a water spray gun features adjustable flow rate and spray range. By selecting different nozzle diameters (55cm, 45cm, 35cm) and using them in combination, users can adjust the irrigation flow rate and range according to their actual needs. This flexibility not only improves irrigation efficiency but also saves water resources.

[0047] Specifically, in standalone mode: only the first water distribution sleeve valve 101 can be opened to allow the first nozzle 91 to work alone; or only the second water distribution sleeve valve 102 can be opened to allow the second nozzle 92 to operate independently; or only the third water distribution sleeve valve 103 can be opened to allow the third nozzle 93 to spray water alone.

[0048] Two-way combination usage modes: When the first water distribution sleeve valve 101 and the second water distribution sleeve valve 102 are opened, the first nozzle 91 and the second nozzle 92 work simultaneously; when the first water distribution sleeve valve 101 and the third water distribution sleeve valve 103 are opened, the first nozzle 91 and the third nozzle 93 spray water in coordination; when the second water distribution sleeve valve 102 and the third water distribution sleeve valve 103 are opened, the second nozzle 92 and the third nozzle 93 work together.

[0049] Three-nozzle combination mode: When the first water distribution sleeve valve 101, the second water distribution sleeve valve 102 and the third water distribution sleeve valve 103 are opened at the same time, the first nozzle 91, the second nozzle 92 and the third nozzle 93 are all put into operation.

[0050] In terms of nozzle design, the first nozzle corresponds to a 55cm diameter nozzle, the second nozzle to a 45cm diameter nozzle, and the third nozzle to a 35cm diameter nozzle. Based on these diverse operating modes, water guns with varying spray volumes can be created, ranging from a 35cm diameter (when only the third nozzle is working) to a 75cm diameter (when the first, second, and third nozzles are working simultaneously, a similar large-diameter spray effect can be achieved through a well-designed nozzle combination; here, the 75cm diameter is based on the equivalent diameter concept corresponding to the comprehensive spray capacity achieved by multiple nozzles working together). This multi-mode design greatly enhances the applicability of the water gun in different scenarios, satisfying both small-scale, precise water spraying operations and large-scale, powerful water spraying needs with a single water gun.

[0051] Furthermore, this invention achieves precise irrigation control. Two auxiliary nozzles are installed next to each main nozzle, controlled by independent on / off valves. This design allows users to open or close the auxiliary nozzles as needed, achieving more precise irrigation control. For example, when a specific area needs irrigation, the corresponding auxiliary nozzle can be opened; when an area does not need irrigation, the auxiliary nozzle can be closed.

[0052] The water-breaking rods or pins installed next to the first, second, and third nozzles of this invention can effectively break up the water flow, forming finer water droplets and improving the uniformity and efficiency of irrigation.

[0053] In this invention, users can switch between different working modes simply by opening and closing the corresponding valves, without any complicated operating procedures. This simple operation method reduces the difficulty of use for users.

[0054] The water spray gun has three main nozzles (first nozzle 91, second nozzle 92, and third nozzle 93) and two auxiliary nozzles next to each main nozzle. Each nozzle is connected to a connecting pipe via a rotary joint to adjust the spray direction.

[0055] This multi-mode rotary water gun controls the opening and closing of corresponding nozzles by switching the valves on each water distribution sleeve. Users can choose to use a single nozzle, two nozzles in combination, or all three nozzles simultaneously, depending on their actual needs, to meet irrigation requirements in different scenarios.

[0056] This utility model has the following advantages:

[0057] 1. Diverse operating modes to meet diverse irrigation needs. The multiple combinations of nozzles provide users with great flexibility, allowing them to select the most suitable nozzle combination according to different irrigation scenarios and needs, such as small-scale precision irrigation or large-area powerful spraying, to achieve precise and efficient irrigation operations.
