[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the invention.

[0032] The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art in understanding and reading the invention. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.

[0033] like Figures 1 to 6 The diagram shows a preferred embodiment of a rotary nozzle structure, which includes: a first central rod 18, a first return spring 20, a driven wheel 9, a fixed cover 8, a nut 7, a nozzle seat structure, a protective sleeve 10, a second return spring 12, a second central rod 14, and a locking nut 16.

[0034] The middle part of the first central rod 18 protrudes outward to form an annular portion 36; the first return spring 20, the driven wheel 9, and the fixed cover 8 are sequentially sleeved on the upper end of the first central rod 18, wherein the two ends of the first return spring 20 abut against the annular portion 36 and the driven wheel 9 respectively, and the driven wheel 9 cooperates with the fixed cover 8 for transmission; the rotating seat 6 extends into the fixed cover 8 and is sleeved on the first central rod 18, and the rotating seat 6 cooperates with the driven wheel 9 through a sawtooth structure; the nozzle seat structure is sleeved on the rotating seat 6 and fixedly installed on the fixed cover 8 by a nut 7; the protective sleeve 10 is installed on the upper end of the first central rod 18, and the inner wall of the protective sleeve 10 cooperates with the driven wheel 9 for transmission through a locking structure; the second return spring 12 is sleeved on the lower end of the first central rod 18; the second central rod 14 is installed on the first central rod 18, and the two ends of the second return spring 12 abut against the protective sleeve 10 and the second central rod 14 respectively; the locking nut 16 is installed on the second central rod 14.

[0035] This device has the following usage methods:

[0036] The nozzle seat structure and the fixed cover 8 are fixed together by the nut 7. In the first step, the protective sleeve 10 is held, causing it to move downwards towards the second central rod 14. During this movement, the sleeve 10 rotates the driven wheel 9 via a locking mechanism. The driven wheel 9, through the locking mechanism, rotates the fixed cover 8. Since the fixed cover 8 is fixed to the nozzle seat structure, it causes the nozzle seat structure to rotate by a certain angle, thus rotating the nozzle 1 on the nozzle seat structure by a certain angle. In the second step, the nozzle 1 rotates by a certain angle but not to the designated position. The hand is released from the protective sleeve 10, and the second return spring 12 restores its deformation, pushing the sleeve 10 back to its initial position. The driven wheel 9 moves upwards under the action of the first return spring 20. Simultaneously, through the serrated structure of the rotating seat 6 and the driven wheel 9, the driven wheel 9 again rotates the fixed cover 8, causing the nozzle seat structure to rotate again. At this point, the nozzle 1 on the nozzle seat structure moves to the designated position, and the movement ends. This device allows for the replacement of different types of nozzles by rotating the nozzle.

[0037] In addition to the above, the present invention also has the following embodiments:

[0038] Furthermore, a rotary nozzle structure is provided, wherein the nozzle seat structure includes: a rectifier 4, a nozzle seat spring 23, a nozzle seat 2, a nozzle seat sleeve 5, and a nozzle 1; the nozzle seat sleeve 5 is fitted onto a rotary seat 6 and fixedly installed on a fixed cover 8 by a nut 7; the rotary seat 6 has a first mounting hole and a second mounting hole at its upper end; the rectifier 4 is installed on the nozzle seat 2; the nozzle seat 2 is correspondingly installed in the first mounting hole and the second mounting hole; and the nozzle seat spring 23 is located between the nozzle seat 2 and the rotary seat 6; a plurality of nozzles 1 are installed on the nozzle seat sleeve 5. Specifically, when the fixed cover 8 rotates, the fixed cover 8 drives the nozzle seat sleeve 5 to rotate, and the nozzle seat sleeve 5 directly drives the nozzle 1 to rotate, thereby allowing the nozzle 1 to be replaced.

[0039] Furthermore, in a rotary nozzle structure, a plurality of first locking blocks 17 extend upward from the driven wheel 9, forming a locking slot 24 between each pair of adjacent first locking blocks 17. A plurality of second locking blocks 25 protrude outward from the lower part of the driven wheel 9 and engage with the inner wall of the protective sleeve 10. Specifically, the inner wall of the protective sleeve 10 has locking slots that engage with the second locking blocks 25. The protective sleeve 10 and the driven wheel 9 are installed through the locking slots and the second locking blocks 25, so that when the protective sleeve 10 is held and the sliding sleeve 10 is rotated, the driven wheel 9 is driven to rotate.

[0040] Furthermore, in a rotating nozzle structure, a plurality of third locking blocks 26 that engage with a locking slot extend downward from the fixed cover 8, and a boss 27 protrudes outward from the upper part of the fixed cover 8. Specifically, the third locking blocks 26 at the lower end of the fixed cover 8 extend into the locking slot 24 on the driven wheel 9, thereby achieving a locking structure engagement between the fixed cover 8 and the driven wheel 9, and the rotation of the driven wheel 9 drives the fixed cover 8 to rotate.
