  • Publication number: 20230381794
    Abstract: The present disclosure provides a rotary sheet-shaped water structure, including a shell assembly and a gear assembly disposed inside the shell assembly. The shell assembly includes a water inlet and a water outlet. Water flows through the gear assembly through the water inlet and is sprayed out of the water outlet. The water inlet has a plurality of oblique surfaces and the water outlet has a water delivery nozzle having a long conical section. In this case, water enters obliquely to impact the gear assembly and flows toward the water delivery nozzle of long conical section at a lower speed, so as to ensure the water sprays can flow out in the form of rotary sheet-shaped structures. The rotary sheet-shaped water structure features less parts, simple structure, easy assembling, stable water delivery, beautiful water sprays and impact comfort.
