AI Technical Summary
Technical Problem
Existing pressure cooker cooling devices are complex in structure and expensive, resulting in low cooling efficiency and an inability to open the lid quickly and safely.
Method used
It adopts a combination structure of water box, check valve and air pipe, and can be connected to pressure cooker in a detachable or non-detachable manner. It uses cold water evaporation to remove heat and achieve rapid cooling. The water vapor condenses and flows back into the water box, which simplifies the structure and reduces costs.
Benefits of technology
It achieves rapid cooling of the pressure cooker, shortening the depressurization time by 50-60%, and features a simple structure, low cost, and improved safety.

Abstract
This invention provides a pressure cooker depressurization and lid-opening cooling device and a pressure cooker, aiming to solve the problems of complex structure and high cost of existing pressure cooker cooling devices. The invention provides a pressure cooker depressurization and lid-opening cooling device, comprising: a water box with a water storage chamber and a connecting part; a water supply channel connecting the water storage chamber and the cooling water chamber; a water inlet with an end cap on the water box; a check valve located at the water supply channel and used to open and close the water supply channel; and a vent pipe, the lower end of which is connected to the upper end of the cooling water chamber, and the upper end of which is connected to the upper end of the water storage chamber. The cooling device only requires a water box with a check valve and a vent pipe, mounting holes on the outer shell of the pressure cooker, and a water tank on the high-temperature component of the pressure cooker to achieve rapid depressurization and cooling of the pressure cooker. Compared with existing circulating water cooling methods, this invention has a significantly simpler structure and lower manufacturing cost.
