It is easy to use, clean and hygienic, and has multiple functions such as steaming, boiling, stewing, and simmering food. Electric rice cookers are now popular in every household and are one of the most frequently used household appliances.

[0003] Electric rice cookers are mainly used for cooking rice. The dirt at the bottom of the pot is mainly the burnt residue of rice grains. The paint on the outer shell of the rice cooker is also corroded because of the frequent overflow of high-temperature rice soup. During the cooking process, the high-temperature rice soup overflows upward and may enter the pressure relief pipe. The rice soup remaining in the pressure relief pipe will gradually block the pressure relief pipe after it dries up. Long-term accumulation will cause the pressure in the rice cooker to increase. The steam cannot be eliminated, causing the temperature to remain high, affecting the original nutrition of the rice. Utility Model Content

The connecting shell 6 is located at the top of the pot cover body 1, the pressure relief cylinder 7 is located at the end of the connecting shell 6 away from the pot cover body 1, the cooling pipe 8 is located inside the connecting shell 6, the movable sleeve 9 is located inside the pressure relief cylinder 7, the spiral groove 10 is opened inside the pressure relief cylinder 7 and is located on the outside of the movable sleeve 9, two groups of pressure relief holes 11 are opened on both sides of the pressure relief cylinder 7, and the compression spring 12 is located at the end of the movable sleeve 9 away from the connecting shell 6. When the gas is introduced into the interior of the airbag 3 and the airbag 3 reaches its limit, the pressure relief treatment can be performed on it through the pressure relief assembly 5 to prevent the gas pressure from being too high, which causes the rice soup to overflow upward.

[0023] The cooling tube 8 is designed with a spiral structure inside the connecting shell 6. The connecting shell 6 is filled with coolant. When the gas is introduced into the cooling tube 8, the spiral structure design of the cooling tube 8 can increase the contact time between the gas and the connecting shell 6. The coolant can be used to cool the gas, and the gas pressure can be reduced after cooling.

[0024] The movable sleeve 9 extends to the interior of the spiral groove 10 and is provided with a movable block. The external structure size of the movable block is designed to correspond to the internal structure size of the spiral groove 10. The movable sleeve 9 is connected to the spiral groove 10 through the movable block, and the movable block is slidably connected to the spiral groove 10, so that the movable sleeve 9 can be slidably connected to the spiral groove 10. When the gas is introduced into the interior of the pressure relief cylinder 7 through the cooling pipe 8, the movable sleeve 9 can be rotated and displaced through the spiral groove 10, and the compression spring 12 can be used to rotate and unload the gas, thereby reducing the gas pressure.
