Abstract

The invention relates to an electric pressure cooker capable of realizing safe pressure relief, which comprises a cooker body, a cooker cover that is positioned above the cooker body and covers the opening of the cooker body and a safe pressure relief unit fixed at the back end of the cooker body, wherein the safe pressure relief unit comprises a box-shaped bracket with a cavity and an elastic element, an upper revolving shaft, a lower revolving shaft and connecting bodies which are arranged in the cavity, the connecting bodies are respectively arranged on the two side walls of the cavity of the box-shaped bracket, the upper revolving shaft and the lower revolving shaft penetrate through the connecting bodies, the elastic element is fixed in the cavity of the box-shaped bracket, and the left end and the right end of the elastic element respectively abut against the lower revolving shaft. When the pressure reaches the limit value, the cooker cover overcomes the elasticity of the elastic element and moves upwards in the opening direction of the cooker cover, so that a gap can be formed between the cooker body and a seal ring to realize the safe pressure relief. The invention can ensure that the pressure relief process can be completed safely, and the pressure in the cooker can be fast and safely relieved even if the air release valve and/or the pressure relief valve are/is blocked, thereby avoiding cooker explosion and ensuring the personal safety of users.

Description

technical field [0001] The invention relates to the field of kitchen cooking utensils, in particular to a pressure rice cooker capable of safe pressure relief. Background technique [0002] With the development of science and technology and the continuous improvement of people's living standards, pressure products (such as pressure rice cookers) are favored by more and more consumers. In order to ensure the safe use of consumers, the pressure rice cooker is generally equipped with a safety pressure relief device. [0003] Existing safety pressure relief devices for pressure rice cookers are generally provided with an exhaust valve and a different pressure valve on the lid of the pressure rice cooker, and the pressure relief is realized through the cooperation of the exhaust valve and the different pressure valve. However, when the exhaust valve and the differential pressure valve are blocked by food or other substances, the safety pressure relief device will fail. If the pr...
