Moreover, the sealing ring 12 is provided with a foam backflow channel for enabling foam accumulated above the sealing ring 12 to flow back to enter the cup body, and meanwhile, a foam extrusion structure for enabling the foam to be extruded and broken can be correspondingly designed on the foam backflow channel.

When the foam in the cup body 13 continuously increases until the foam enters the cup cover cavity 113, the top closed foam is partially pressed and self-broken, and partial foam is extruded into the inner channel hole 114 under the action of external pressure, then enters the exhaust cavity and is accumulated outside the foam backflow channel, and at the moment, the gas seeks an air outlet under the pressure in the cup body, namely, the gas in the cup body 13 reaches the upper part of the sealing ring 12 and is exhausted out of the cup body 13 from the outer channel hole 110-2; the foam entering the exhaust cavity is continuously accumulated, broken and accumulated again, and when the accumulation speed exceeds the breakage speed, the foam can be slowly broken and returned into the cup body 13 along the foam return channel under the action of the foam extrusion structure.

As shown in fig. 11, the upper portion of the outer ring of the seal ring 12 is provided with an upper seal rib 121, and the lower portion is provided with a lower seal rib 122. Wherein the upper sealing rib 121 is provided with a drainage port 121-1, and the lower sealing rib 122 is provided with a reflux port 122-1. The drainage port 121-1 and the backflow port 122-1 are respectively located at two ends of the foam backflow channel, and foam is gradually extruded through the upper sealing rib 121, the drainage port 121-1, the lower sealing rib 122 and the backflow port 122-1 to form a foam extrusion structure.

As shown in fig. 12 to 14, for the assembly completion schematic diagram of the food processor, the triggering rib 116 is inserted into the cup body 13 for power on triggering, when the food material is added into the cup body 13 and then the cup body 13 starts to work, the cup body work is divided into two processes of stirring and heating, and the stirring and heating processes are analyzed separately as follows:

when the cup body 13 is in a stirring state, the inner part of the cup cover cavity 113 is in a vortex shape, and the food material is in a vortex shape under high-speed rotation, and at the moment, the food material rotates in the cup cover vortex cavity, so that the advantages that the food material is stirred in the vortex cavity smoothly, and high noise caused by stirring impact due to large resistance is avoided; on the other hand, because the top of the cup cover cavity 113 is provided with no hole, the noise above the food material stirring cup cover can be greatly attenuated. When the food material may be thrown to the inner channel hole 114 under vigorous stirring, the food material entering the inner channel hole 114 will flow from the drainage port 121-1 of the upper sealing rib 121 to the lower sealing rib 122 under its own weight, and then the food material slowly accumulates on the surface of the lower sealing rib 122 and gradually extends to both sides, flows to the backflow port 122-1 along the surface of the lower sealing rib 122, and then falls into the cup body 13 along the trend after reaching the drainage port 122-1.

When the cup body 13 is in a heating state, a large amount of foam is formed after the food material is heated violently and rises gradually, when the food material rises vertically to the cup cover cavity 113, the foam part closed at the top is broken by itself due to the pressure, and part of the foam is extruded into the inner channel hole 114 under the action of external pressure and then enters the drainage port 121-1 of the upper sealing rib 121, and at the moment, the gas is searched for a gas outlet under the internal pressure of the cup body, namely, the gas in the cup body 13 reaches the upper part of the upper sealing rib 121 and is discharged out of the cup body 13 from the outer channel holes 110-2 at two sides; foam entering the drainage port 121-1 is continuously accumulated, broken and then accumulated, when the accumulation speed exceeds the breakage, the foam is slowly accumulated to the backflow port 122-1 of the lower sealing rib 122 along the drainage port 121-1, and the foam cannot cross the upper sealing rib 121 because the upper sealing rib 121 on the top of the backflow port 122-1 is tightly attached to the cup body 13, so that the foam is slowly broken and flows back into the cup body 13.

It is understood that, in this embodiment, referring to the second embodiment, the vertical blocking rib 117 is disposed inside the lid cavity blocking rib 110, so that the lid inner cavity 113-1 and the lid outer cavity 113-2 are also formed.

Furthermore, the number of the drainage ports 121-1, the transition ports 124-1 and the return ports 122-1 is more than two and is uniformly distributed along the circumferential direction of the sealing ring 12, the size of at least two drainage ports 121-1 can be the same, the size of at least two transition ports 124-1 can be the same, the size of at least two return ports 122-1 can be the same, and the drainage ports 121-1, the transition ports 124-1 and the return ports 122-1 are staggered along the circumferential direction of the sealing ring 12. Because the drainage port 121-1, the transition port 124-1 and the backflow port 122-1 are staggered along the circumferential direction of the sealing ring 12, a space is provided for accumulation and final rupture of foam, so that the foam can be intermittently accumulated, ruptured and re-accumulated above the upper sealing rib 121, between the upper sealing rib 121 and the middle sealing rib 124 and between the middle sealing rib 124 and the lower sealing rib 122, and the ruptured foam flows back into the cup body 13; as the number of the drainage ports 121-1, the transition ports 124-1 and the backflow ports 122-1 can be more than two and are uniformly distributed along the circumferential direction of the sealing ring 12, a plurality of backflow channels are formed, and broken foams can flow back into the cup body 13 in time.

The principle of the anti-overflow and exhaust gas during the stirring and heating process is described in detail as follows:

when the cup body 13 is in a stirring state, the food material thrown to the inner channel hole 114 under vigorous stirring flows from the drainage port 121-1 of the upper sealing rib 121 to the middle sealing rib 124 under the self gravity, then the food material on the middle sealing rib 124 is slowly stacked and slowly extends from two sides, when the food material extends to the transition port 124-1, the food material falls to the lower sealing rib 122, and the food material continues to be stacked on the surface of the lower sealing rib 122 and extends until the food material reaches the backflow port 122-1, and finally flows back into the cup body 13.

When the cup body 13 is in a heating state, a large amount of foam is formed after the food material is heated violently and rises gradually, when the food material rises vertically to the cup cover cavity 113, the foam part at the top part is broken by self due to pressure, part of the foam is squeezed into the inner channel hole 114 under the action of external pressure and then enters the drainage port 121-1 of the upper sealing rib 121, at the moment, the internal air pressure of the cup body is higher, along with the increasing of the steam quantity, the foam rises to the surface of the cup cover cavity 113 and is condensed into liquid state to be attached and accumulated, and finally flows back to the cup body 13, and the steam entering from the inner channel hole 114 moves towards the upper side and the two sides and can be discharged outside when reaching the outer channel hole 110-2. Meanwhile, the more the foam in the cup body 13 is gathered, the foam is continuously accumulated, broken and accumulated again after entering the drainage port 121-1, when the accumulation speed exceeds the breakage, the foam is slowly accumulated and climbs to the surface of the middle sealing rib 124 along the drainage port 121-1, the foam is continuously accumulated to reach the transition port 124-1 and then is extruded to the lower sealing rib 122 under the blocking of the upper sealing rib 121, meanwhile, the foam is continuously accumulated, when the foam is accumulated and extruded to the backflow port 122-1, the broken foam flows back to the cup body 13 from the backflow port 122-1, and part of the accumulated foam which is not broken is gradually extruded and broken under the blocking of the middle sealing rib 124 and finally flows back to the cup body 13.
