This utility model relates to the field of water rocket landing chamber technology and discloses a water rocket parachute chamber, including a water rocket body. A disc is provided on the top of the water rocket body, and a through mounting hole is opened on the disc. The disc is fitted onto the top of the water rocket body through the mounting hole.

This utility model relates to a delayed-release air-separation lower-stage rocket assembly connector for water rockets, used to connect two rocket bodies to form a single lower-stage rocket body. The assembly connector has a hollow screw body and a one-way valve body that is hollowly connected to the interior of the hollow screw body. The assembly connector also has a micro-hole communicating with an internal airflow channel of the hollow screw body. When the lower-stage rocket body is assembled, the micro-hole and the one-way valve body are located within the same rocket body, and the hollow screw body extends into the other rocket body. During water rocket launch, after the lower rocket body loses pressure, the air pressure in the upper rocket body can only be slowly released to the lower rocket body through the micro-hole. This significantly prolongs the depressurization time in the upper rocket body, thereby extending the time for triggering the air-separator assembly to achieve release and separation. This extends the separation time between the upper and lower rocket bodies, allowing for an interval of 1-2 seconds between launch and separation, which is more than 10 times longer than existing technologies.
