It can be seen that in this state, the vent valve assembly 10 is primarily used for venting and adding flavorings.

When the food material is beaten by the wall breaking machine, the pressure in the stirring cup is equal to the environmental pressure, the float valve 13 and the valve cavity 113 form a sealed cavity, and the noise generated by the collision of the stirring knife assembly 23 and the liquid is prevented from being transmitted to the environment.

When the stirring cup is heated and stirred simultaneously, the liquid of the stirring cup is heated continuously to generate gas, the pressure in the stirring cup is higher than the ambient pressure, the float valve 13 moves to the second position, and the gas and noise are discharged from the second through hole 134 of the float valve 13 to the valve cavity 113 (expansion cavity) to enter the environment, so that the excessive pressure in the stirring cup is avoided. The noise passes through the expansion cavity structure inside the valve body 11, and the noise has certain dissipation, thereby realizing the amortization.

After the stirring cup is heated, the temperature in the stirring cup is higher than the ambient temperature and gradually decreases, the pressure intensity is approximately equal to the ambient pressure intensity, the float valve 13 decreases due to the self gravity, the temperature in the stirring cup continues to decrease, and the air density in the stirring cup is lower than the ambient density, so that negative pressure is formed in the stirring cup, the float valve 13 and the stirring cup form a sealed environment, the oxidation of food materials can be effectively slowed down, and the fresh-keeping effect is achieved.
