AI Technical Summary
Technical Problem
Existing toilets have a strong siphon force when draining, which leads to insufficient water seal height recovery and affects the odor prevention effect, especially the problem is more serious with pressure flush toilets.
Method used
Design a sealing ring comprising a flange, a flexible seal, and an air intake assembly. The air intake assembly has a one-way valve and a connecting pipe for drawing in air when a negative pressure is generated by the siphon, eliminating the negative pressure, and preventing the water seal from being drawn away.
Benefits of technology
The air intake component design eliminates the negative pressure generated by the siphon, ensuring the continuity of the toilet water seal and preventing odor from escaping.
