Induction cooker overflow protection device based on thermal expansion and cold contraction of gas

An induction cooker overflow protection device based on thermal expansion and cold contraction of gas relates to the technical field of household appliances. The device comprises a cooker body, wherein a heating device is fixedly connected to the middle of the cooker body, electric heating blocks are fixedly connected to the inner bottom walls of two sides of the cooker body, resistors electrically connected with the electric heating blocks are fixedly connected to the inner walls of two sides of the cooker body, and the inner wall of the cooker body is fixedly connected with negative plates electrically connected with the resistors. According to the induction cooker overflow protection device based on thermal expansion and cold contraction of gas, through cooperative use of the electric heating blocks and electric contacts, when water exists on the upper surface of the induction cooker, the water flows into a water collecting tank, the two electric contacts are electrically connectedat the moment, a circuit
