[0023] A pressure device for a micro-pressure cooking appliance, comprising a pot body 1 having a accommodating cavity and a pot cover 2 arranged on the pot body 1, the pot cover 2 being provided with an air leakage channel 3 for exhaust and pressure relief, which is connected to the pot body 1 and the outside, a first sealing ring 4 for sealing the air leakage channel 3 is penetrated in the air leakage channel 3, the first sealing ring 4 is axially provided with an air leakage port 40 which can be communicated with the air leakage channel 3, the air leakage port 40 is provided with a counterweight valve body 5 which can block the air leakage port 40, when the air pressure in the pot body 1 is greater than the gravity of the counterweight valve body 5, the counterweight valve body 5 can be lifted up along the axial direction of the air leakage port 40 to allow the air to escape. The gas can be discharged from the air release port 40 to the air release channel 3. The counterweight valve body can automatically respond according to the internal air pressure conditions, release excess gas in time, effectively reduce pressure, and ensure safe use by users. When the pressure exceeds the limit, the counterweight valve body can be quickly lifted up and the air release port can be opened to allow the gas to be discharged quickly, thereby accelerating the exhaust and pressure relief process, shortening the cooking time, and improving efficiency. The structure is simple and the function is clear, and the operation is convenient. Users do not need to perform too much operation to achieve pressure relief, which lowers the usage threshold and improves user experience.

The setting of the transparent cover plate 24 allows the user to clearly observe the cooking process of the food and is convenient for grasping the cooking progress. The design of the second sealing ring 23 further enhances the sealing performance, effectively prevents the leakage of gas or water vapor, and ensures the quality and taste of the cooking. The overall design is simple and practical, and is easy to clean and maintain.

[0028] Preferably, the transparent cover plate 24 is also provided with a handle 6 for opening the pot body 1, so that the user can open the pot cover conveniently.

[0029] Preferably, the handle 6 is further provided with a recessed portion 60 sunken toward the pot body 1 , so that when in use, the user can conveniently place tools such as soup spoons and rice spoons on the recessed portion, thereby saving space.
