[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art are within the protection scope of the present utility model.

[0024] Embodiments of this utility model:

[0025] like Figures 1-2 As shown, the self-generating booster spray gun includes a main water pipe 1, to which a power-generating spray pipe is connected. The power-generating spray pipe includes a pipe body 7 and a nozzle 8 located at one end of the pipe body 7. The main water pipe 1 is the main pipeline for irrigation, with a large water output and long range. The power-generating spray pipe is mainly used for power generation, utilizing the power of the water flow itself. The diameter of the power-generating spray pipe is relatively small, and its length is relatively short.

[0026] A generator 3 is connected to the outer periphery of the main water spray pipe 1. The housing of the generator 3 is fixed to the mounting arm, which is secured to the main water spray pipe 1 by clamps. A first impeller 2 is mounted on one end of the rotor in the generator 3. The first impeller 2 is located below the generator 3, and the rotation axis of the first impeller 2 is coaxial with the rotation axis of the rotor.

[0027] The first impeller 2 includes several blades distributed circumferentially, with each blade positioned around the axis of rotation of the first impeller 2. The water jet from the nozzle 8 is directed towards the first impeller 2, and the water flow from the nozzle 8 causes the blades of the first impeller 2 to rotate. This rotation of the first impeller 2, in turn, causes the generator 3 to generate electricity. The output current and voltage parameters of the generator 3 can be designed according to the needs of the power user, which is a conventional technique in this field. A voltage regulator is integrated into the generator to ensure stable output.

[0028] like Figures 3 to 5As shown, the pipe body 7 is an L-shaped pipe, and one end of the nozzle 8 has a spherical connecting part 81. The end of the pipe body 7 connecting to the nozzle 8 has a spherical structure 71, which mates with the spherical connecting part 81. Most of the spherical connecting part 81 is located within the spherical structure 71 to form a ball-joint structure, allowing adjustment of the nozzle 8's angle. The other end of the nozzle 8 has a tapered structure, reducing the diameter to increase the outlet water pressure. One end of the pipe body 7 has an external thread 72 and is threadedly connected to a locking ring 9. The locking ring 9 has a locking surface 91 of the spherical structure 71, used to lock the nozzle 8 after its angle is adjusted. After locking, the locking surface 91 presses against a portion of the spherical structure 71 of the nozzle 8. When adjusting the nozzle 8's angle, the locking ring 9 is first loosened. The outer circumference of the locking ring 9 has lugs for hand gripping and easy rotation.

[0029] A booster structure is connected to the end of the main water spray pipe 1 furthest from its nozzle 11. The booster structure includes a booster motor 5 and a second impeller (not shown), which is located inside the main water spray pipe 1. The fixed part of the booster motor 5, i.e., the outer casing, is connected to the main water spray pipe 1. The booster motor 5 drives the second impeller to rotate, and the electrical energy required by the booster motor 5 is supplied by the generator 3. The booster motor 5 is a DC motor. By using the water flow from the spray gun itself to generate power and also to rotate the second impeller, no external power supply is needed, which not only saves energy but also makes it convenient to use. The structure of the second impeller for boosting is not shown in the figure. When the second impeller rotates at high speed under the drive of the booster motor, it uses centrifugal force to draw water from the low-pressure area and compress it to the high-pressure area, which can increase the outlet water pressure of the main water spray pipe 1 and increase the outlet water speed. This boosting method is similar to the principle of a car turbocharger, but the application scenario is different. In other embodiments, an external power supply can also be used to power the booster motor 5.

[0030] In other embodiments, a built-in battery is incorporated in the generator to power the booster motor. In other embodiments, the self-generating booster spray gun includes a battery compartment; the battery compartment houses a battery that powers the booster motor; the battery compartment can be installed on the outer periphery of the main spray pipe 1 or on the outer periphery of the rotating base 6, with its output positive and negative terminals connected to the booster motor via cables. The corresponding battery housing features a waterproof design, which is achievable with existing technology and will not be described further.

[0031] like Figure 1As shown, the booster motor 5 and the main water spray pipe 1 are coaxially arranged. The outer casing of the booster motor 5 can be connected to one end of the main water spray pipe 1 through a flange and sealing ring. Compared with the known structure disclosed in the prior patent, in order to install the booster motor 5, a connection hole is opened at the junction of the main water spray pipe 1 and the rotating seat 6, which is made into a flange hole. In other embodiments, the outer casing of the booster motor 5 can also be threadedly connected to the main water spray pipe 1. The rotating seat 6 is hollow, and the water flow first passes through the inner cavity of the rotating seat 6 and then flows into the main water spray pipe 1, and is sprayed out from the spray nozzle 11 of the main water spray pipe 1. In other embodiments, a pair of gears of different sizes can also be used between the output shaft of the booster motor and the second impeller to increase the speed of the second impeller. In this case, the output shaft of the booster motor and the second impeller are not coaxially arranged, and the booster motor is offset from the main water spray pipe.

[0032] This utility model's self-generating booster spray gun mainly adds a booster structure. The existing structure that uses a generator-driven water pipe to generate electricity for lighting can be omitted, or a flashlight or other light fixture can be added. The main water pipe 1 is also equipped with a flashlight. The generator 3 supplies power to the flashlight via a first cable and to the booster motor 5 via a second cable 4. Figure 1 As shown. With the lights installed, the system can generate its own water power for illumination, allowing the spray gun to function normally even in low-light conditions at night. If the flashlight is removed, the booster motor 5 and generator 3 are electrically connected via a cable. To facilitate cable stability, wire clamps (using existing technology) can be installed on the casing of the booster motor 5 and the main water spray pipe 1. After the cable passes through the groove of the wire clamp, it is tightened with screws.
