[0015] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0016] This invention uses a switching element to guide water flow into a rotating water assembly, which in turn generates rotating water splashes.

[0017] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0018] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0019] Figures 1 to 8 A quick-switching rotary water spray gun according to an embodiment of the present invention includes: The switch assembly 1 consists of a housing 11 and a switch element 12. The housing 11 has a cavity for the switch element 12 to move within the housing 11. The switch element 12 moves within the housing 11 and has a water flow channel 121, which has an inlet 122 and an outlet 123. The inlet 122 moves with the switch element 12 and is connected to or closed by the inlet 122 of the housing 11. The outlet 123 is connected to a rotating water assembly disposed in the housing 11. Specifically, the switching element 12 includes a movable section 124 and an enlarged section 125. One end of the movable section 124 is hinged to the handle 2 located outside the housing 11, and the other end forms the enlarged section 125. The water flow channel 121 is located inside the enlarged section 125, and a sealing element is provided around the outside of the enlarged section 125 in a circumferential direction. A spring is sleeved on the outside of the movable section 124, with one end of the spring abutting against the enlarged section 125 and the other end abutting against the housing 11.

[0020] When in use, pressing the handle 2 causes the switching element 12 to move axially. During this process, there are sealing rings between the moving section 124 and the enlarged section 125 and the outer casing 11, so water will not spray out from the gaps in the moving area. The function of the spring is to maintain the initial position of the switching element 12, that is, to keep the enlarged section 125 out of contact so that the entire spray gun does not spray water. As the handle 2 is pressed continuously, the water inlet 122 on the enlarged end gradually aligns with the water inlet pipe, so that external pressurized water can enter through this, reach the water outlet 123 through the water flow channel 121, and then the water outlet 123 guides the water flow to the rotating water assembly.

[0021] A rotating nozzle is provided in the outer casing 11. The top of the cavity 53 is conical and narrowed and is provided with a first water spray nozzle 511. The bottom of the cavity 53 is provided with an annular limiting groove 521. The annular limiting groove 521 is coaxially arranged with the first water spray nozzle 511. The cavity 53 is provided with a water inlet channel 522 and a water outlet channel 523 at the annular limiting groove 521. Water flows through the water inlet channel 522 into the annular limiting groove 521 and is discharged from the water outlet channel 523 to form a rotating water flow in the cavity 53. Rotating body 54 is freely movable inside cavity 53. Rotating body 54 is provided with second water nozzle 5411 and water inlet hole 5421 communicating with second water nozzle 5411 and cavity 53. The lower end of rotating body 54 extends into annular limiting groove 521. The rotating water flow inside the cavity 53 can drive the lower end of the rotating body 54 to revolve within the annular limiting groove 521, and the second water nozzle 5411 can remain in contact with the first water nozzle 511 to achieve rotating water spraying.

[0022] Rotary nozzle 5 is installed on housing 11 to rotate and spray water from water chamber 4. The rotating nozzle 5 includes: The cavity 53 has a tapered top with a first water nozzle 511 and an annular limiting groove 521 at the bottom. The annular limiting groove 521 is coaxially arranged with the first water nozzle 511. The cavity 53 has an inlet channel 522 and a drain channel 523 at the annular limiting groove 521. Water flows through the inlet channel 522 into the annular limiting groove 521 and is discharged from the drain channel 523 to form a rotating water flow inside the cavity 53. Rotating body 54 is freely movable inside cavity 53. Rotating body 54 is provided with second water nozzle 5411 and water inlet hole 5421 communicating with second water nozzle 5411 and cavity 53. The lower end of rotating body 54 extends into annular limiting groove 521. The rotating water flow inside the cavity 53 can drive the lower end of the rotating body 54 to revolve within the annular limiting groove 521, and the second water nozzle 5411 can remain in contact with the first water nozzle 511 to achieve rotating water spraying.

[0023] In other words, external water is injected into the cavity 53 through the water inlet channel 522 of the rotating nozzle 5. After entering, the water flows along the annular limiting groove 521 to the drainage channel 523, forming a rotating water flow inside the cavity 53. The rotating water flow can directly act on the rotating body 54 to provide rotational driving force for the rotation of the rotating body 54. The top of the cavity 53 is conical and narrowed. When the rotating body 54 is filled with water in the cavity 53, the rotating body 54 tends to move towards the top of the cavity 53, so that the second spray nozzle 5411 remains in contact with the first spray nozzle 511 at the top of the cavity 53. At the same time, the annular limiting groove 521 can limit the lower end of the rotating body 54, so that the lower end of the rotating body 54 is restricted to rotate within the annular limiting groove 521. In this way, the water flow in the cavity 53 is sprayed out through the water inlet hole 5421 of the rotating body 54 by the second spray nozzle 5411. The cavity 53 is provided with a central column 524 that protrudes from its bottom wall toward the top of the cavity 53. An annular limiting groove 521 is formed between the outer peripheral wall of the central column 524 and the inner peripheral wall of the cavity 53. The cavity 53 can be formed by connecting the upper shell 51 and the lower shell 52 to facilitate the installation of the rotating body 54. The first water nozzle 511 is provided on the upper shell 51, and the annular limiting groove 521, the water inlet channel 522 and the drainage channel 523 are provided on the lower shell 52. The water inlet hole 5421 can be provided on the side or bottom of the rotating body 54. The diameter of the outer wall of the second water nozzle 5411 can be larger than the diameter of the first water nozzle 511. Thus, water flows into the rotating nozzle 5, forming a rotating water flow, which provides rotational driving force for the rotating body 54 inside the cavity 53. The rotating body 54 rotates and sprays water out in a rotating manner. This shower rod has a simple structure, a wide spray range, and can optimize the user's showering experience.

[0024] Optionally, the rotating body 54 has a structure that is larger in the middle and smaller at both ends in the axial direction. Understandably, the top of the rotating body 54 is used to mate with the tapered constriction at the top of the cavity 53, the middle part of the rotating body 54 is used to mate with the inner wall of the middle part of the cavity 53, and the bottom of the rotating body 54 is used to mate with the annular limiting groove 521. When the rotating body 54 revolves, the top of the rotating body 54, in mate with the tapered constriction, forms a fulcrum-like function, and the middle part of the rotating body 54, in contact with the inner wall of the cavity 53, provides a supporting abutment, allowing the rotating body 54 to rotate simultaneously with its own rotation. This reduces the rotational resistance of the rotating body 54 and improves the smoothness of its rotation. The bottom of the rotating body 54, in mate with the annular limiting groove 521, restricts the lower end of the rotating body 54 to rotate along a designated path. The cavity 53 and the rotating body 54 are arranged to match the contour of their revolution. The bottom of the rotating body 54 is provided with a limiting post 5423, which is coaxially arranged with the second water nozzle 5411.

[0025] Furthermore, there are multiple water inlet holes 5421, which are located at the bottom of the large central section of the rotating body 54 and spaced apart around the axis of the rotating body 54. Understandably, the large central section of the rotating body 54 provides space for multiple water inlet holes 5421. Distributing these holes around the axis allows the rotating water flow within the annular limiting groove 521 to enter each water inlet hole 5421 more evenly, avoiding problems such as excessive local pressure or uneven center of gravity distribution caused by concentrated water flow in a single water inlet hole 5421. This reduces jamming caused by uneven force during rotation of the rotating body 54, ensuring stable rotation speed and uniform water flow during showering. Simultaneously, the multiple water inlet hole design improves water intake efficiency, prevents interruptions in water flow due to blockage of a single hole, and ensures the continuity of the shower process.

[0026] Furthermore, the isolation zone between adjacent water inlets 5421 forms a water-blocking section 5422. Understandably, the water-blocking section 5422 serves as the outer wall of the water inlet 5421, and also increases the force of the rotating water flow on the rotating body 54, so that the rotating water flow can more easily drive the rotating body 54 to rotate. The multiple water-blocking sections 5422 are arranged radially.

[0027] Optionally, the outer peripheral wall of the second nozzle 5411 is constricted along the water flow direction. Understandably, by constricting the outer peripheral wall of the second nozzle 5411, the second nozzle 5411 can fit more closely to the inner wall of the first nozzle 511, reducing the obstruction of the first nozzle 511 on the second nozzle 5411, increasing the rotation angle of the second nozzle 5411, and achieving a larger range of rotational spray. Specifically, the cavity 53 extends downwards from the first nozzle 511 with an annular protrusion 512. The annular protrusion 512 has a conical constriction, and the top of the conical constriction is provided with the second nozzle 5411. The rotating body 54 has a groove 5412 at the lower edge of the annular protrusion 512. The groove 5412 and the lower edge of the annular protrusion 512 can make way for each other during the rotation of the rotating body 54, allowing the rotating body 54 to achieve a larger range of rotation.

[0028] Optionally, both the inlet channel 522 and the outlet channel 523 are tangentially connected to the annular limiting groove 521. Understandably, the inlet channel 522 allows water to flow in tangentially to the annular limiting groove 521, minimizing the impact force on the inner and outer walls of the annular limiting groove 521. This allows water to flow smoothly into the annular limiting groove 521 and then smoothly out of the outlet channel 523 tangentially. This generates a stable rotating water flow without additional structural guidance, resulting in a simple and reliable structure. The inlet channel 522 and the outlet channel 523 can be symmetrically distributed with a 90° rotation.

[0029] Furthermore, the rotating body 54 includes a first part 541 and a second part 542 connected to the first part 541. A second water nozzle 5411 is disposed in the first part 541, and a water inlet 5421 is disposed in the second part 542. Understandably, by separating the rotating body 54 into two parts, the processing difficulty of the rotating body 54 can be greatly reduced, thereby lowering manufacturing costs. Water flows into the first part 541 through multiple water inlets 5421, then converges in the second part 542 and is ejected from the second water nozzle 5411. The first part 541 and the second part 542 can be connected by a sleeve connection or by ultrasonic welding.
