Description

A New Multifunctional Electric Pressure Cooker

technical field

The utility model relates to an electric pressure cooker, in particular to a novel multifunctional electric pressure cooker which is safe to use.

Background technique

Existing electric pressure cooker is of a great variety, and along with the continuous improvement of people's material living standard, its function is also more and more, and in order to enhance the safety of its use, safety valve, pressure limiting valve and A knob assembly that can make the pot cover and the pot body be in a tightly fastened or open state, as shown in an electric pressure cooker disclosed in Patent No. ZL98215733, which adopts a knob that can be interlocked with its lock ring on the pot cover , pressure control switch and lever mechanism, so that the pot lid and the pot body can be locked and sealed or opened through the knob assembly, which is more convenient and safe to use, but the fly in the ointment is: because there is no There is any detection device that can detect whether the lock ring and the inner pot are closed by the knob assembly, so that when the existing electric pressure cooker is in use, it is impossible to accurately judge whether the lid is locked with the inner pot safely, but it is realized by guessing. Therefore It is easy to start the electric control switch to work when the pot cover and the inner pot are not locked and cause people to be scalded, waste power and other events, so its structure is unreliable and unsafe to use. In addition, the pot lids of existing electric pressure cookers are mostly not equipped with an electric protection device to control the power on and off of the electric control device on the main body of the pot, so that the electric control switch will be activated by children randomly pressing or adults accidentally pressing the switch on the electric control device of the pot main body. It is extremely unsafe to use due to the occurrence of incidents such as burning out the pot body, people being scalded, wasting power supply, etc. due to work. In addition, existing electric pressure cookers mostly have a slot set on a rotating connecting rod of the knob assembly and a post on the lock ring, and then the slot is inserted into the post on the lock ring to realize the rotation with the knob. The purpose of opening and closing the cover, the voltage cooker with this structure, firstly, the length of the connecting rod is long, and the production cost is high; secondly, the long connecting rod is used for a long time under the condition of large torque at both ends, it is easy to break, and the service life is short , so the existing electric pressure cooker cannot satisfy the requirements of consumers in general.
