[0023] A sealing ring 8 is arranged between the outlet of the water outlet pipe 1 and the water outlet disc 3.

[0024] The working principle of the utility model is as follows:

[0025] Water flow acceleration: when the compressed air in the water storage tank of the water rocket is released, the spiral thread of the water outlet pipe makes the water flow rotate, increases the kinetic energy of the water flow, and thus improves the jet speed;

[0026] Jet control: the water flow is sprayed through the jet holes on the water outlet disc, and the hole diameter and number of the jet holes determine the dispersibility of the water flow and the thrust size;

[0027] Thrust adjustment: the user can replace the water outlet disc with different hole diameters according to needs to adjust the thrust of the water rocket. For example, a smaller hole diameter (such as 3mm) is suitable for high thrust and short time jet, and a larger hole diameter (such as 10mm) is suitable for low thrust and long time jet.

[0028] Sealing: the sealing ring ensures that the connection between the water outlet pipe and the water outlet disc is not water-leaking, and the energy of the compressed air is maximally utilized.

[0029] The water jet port design of the water rocket solves the problems of low propulsion efficiency, unadjustable thrust and inconvenient maintenance of traditional water rockets through innovative designs such as spiral thread, detachable water outlet disc and sealing ring, has the characteristics of reasonable structure, superior performance, flexible use and the like, and is suitable for various scenes such as education, entertainment and scientific research.

[0030] The utility model and its implementation modes are described above, which is not restrictive, and the embodiment shown in the drawings is only one of the embodiments of the utility model, and the actual structure is not limited thereto.
