AI Technical Summary

⚠Technical Problem

The top spray arm of existing cleaning machines is prone to bending, deformation and sagging, and the head loss is relatively large, which affects the cleaning effect, especially in large-scale models.

⚗Method used

The system employs a horizontally arranged water inlet pipe and a clamping ring structure with the spray arm. The water inlet pipe is locked to the top wall of the cleaning machine, and the spray arm is constrained under the water inlet pipe by the rotation of the clamping ring, ensuring that the spray arm is connected to the inner water pipe, reducing head loss and improving installation reliability.

🎯Benefits of technology

This effectively avoids the problem of spray arm sagging, reduces head loss, and increases spray coverage, thereby improving the cleaning effect.

Abstract

This utility model relates to a spray assembly for a cleaning machine and the cleaning machine itself, including a horizontally arranged water inlet pipe and a spray arm. The lower surface of the water inlet pipe has an outlet, and the top of the spray arm has an inlet connected to the outlet. The top of the water inlet pipe is locked to the top wall of the cleaning machine, with the locking point corresponding to the outlet. The spray arm is rotatably constrained below the water inlet pipe by a retaining ring. This utility model locks the top of the water inlet pipe to the top wall of the cleaning machine, providing sufficient support for the spray arm below the pipe, improving installation reliability, and preventing the spray arm from sagging due to bending or deformation of the water inlet pipe end. The spray arm is rotatably constrained below the water inlet pipe by the retaining ring. The spray arm can be connected to the internal water pipe in the cleaning machine through the water inlet pipe. The stable constraint of the water inlet pipe at the top of the cleaning machine ensures stable rotation of the spray arm, reduces head loss, and guarantees spray coverage, thus improving the cleaning effect.
