AI Technical Summary

Technical Problem

The single pressure relief vent of existing pressure cookers is easily clogged by food and soup, resulting in incomplete pressure relief and a risk of the cooker exploding.

Method used

The high-temperature cooking pot lid features a multi-vent pressure relief design, employing a sliding gap structure composed of baffles and support springs. Combined with dual filtration of raised rings and spiral guide rings, along with multiple pressure relief pipes and one-way valves, it forms a self-closing circulation mechanism to ensure rapid, segmented release and cooling of steam.

Benefits of technology

It effectively reduces the possibility of food scraps clogging the pressure relief pipe, ensures rapid release of high-pressure steam, avoids the risk of pot explosion, reduces the probability of burns, and ensures the reliability of the structure under high-temperature conditions.
