First, the technical idea of the technical solution disclosed in the present invention will be explained. In order to enhance the sealing effect, the sealing element arranged on the cup cover assembly of the traditional food processor is formed into a cavity structure capable of generating large deformation, so that when the cup cover assembly covers the cup body assembly, the sealing element can be extruded by the cup cover assembly, and the extrusion deformation of the sealing element is increased to improve the sealing effect between the cup cover assembly and the cup body assembly. But because food preparation machine's slurrying process needs carry out continuous heating to the processing chamber inside, lead to processing chamber inside temperature higher, and when slurrying accomplished and need wash the processing chamber, the water of pouring into to the processing chamber then is normal atmospheric temperature water, leads to processing chamber inside temperature shock, cavity that forms along with the area sealing member takes place to shrink because of the temperature reduces, leads to the inefficacy of sealing member short time, the gap grow between bowl cover subassembly and the cup body assembly, wash water and easily spill over, influence user's use and experience. In view of the above problems, the cup cover assembly with the optimized sealing structure and the food processor using the same disclosed by the application reduce the influence of the volume change of the cavity caused by the temperature change on the sealing.

The specific scheme is as follows:

When the gap 14 is used as a pressure balance structure, the resistance of the air flow is minimal when the cavity 13 is communicated with the outside, and the outside air can be quickly filled into the cavity 13, so that the sealing element 12 is quickly deformed, and the sealing reliability of the cup body assembly 20 and the cup cover assembly 10 is maintained.

In one embodiment, the cover comprises a cover cup 111 and a bracket 112 for connecting the cover cup 111 to the cup body, the cover cup 111 is used for forming an upper cavity, the cup body is used for forming a lower cavity, and the cover cup 111 covers the cup body to form a complete processing cavity. The bracket 112 is fixedly connected to the cover cup 111 to maintain stability of the cover cup 111 when connected to the cup body. In order to ensure that the sealing member 12 is reliably fixed, the sealing member 12 is disposed on the bracket 112, and in the present embodiment, the sealing member 12 is clamped between the bracket 112 and the cup body, and partially extends to the lower surface of the bracket 112 to flexibly abut against the cup body, thereby achieving a reliable sealing effect. A cavity 13 is formed below the bracket 112 to provide sufficient deformation space when the cups abut. Further, in order to avoid the sealing effect being influenced by the excessive deformation of the sealing element 12, in this embodiment, the support rib 1123 of the support cavity 13 is further arranged on the outer surface of the support 112 in a protruding mode, one or more support ribs 1123 are distributed along the circumference of the bottom surface of the support 112, the support rib 1123 extends into the cavity 13, and part of the cavity 13 space is filled, on the premise that the deformation of the cavity 13 is not influenced, the support of the cavity 13 is realized from the inside, the cavity 13 can be prevented from collapsing, when the air pressure inside and outside the cavity 13 is prevented from being changed remarkably and shrinking, the excessive deformation of the position of the pressure balance structure is formed, sufficient sealing effect can be provided by using sufficient deformation space, the sealing effect is enabled to be effective for a long time, and the reliability is higher.

From the aspect of mold opening and mold drawing, if the turnbuckle 1124 and the support rib 1123 are disposed at the same position, the turnbuckle 1124 will shield the support rib 1123, and the small gap formed therebetween is not favorable for mold drawing. In practical terms, the turnbuckle 1124 also needs to be dislocated and avoided from the support rib 1123 so as to avoid the interference of the support rib 1123 to the screwing process when the lid assembly 10 and the cup assembly 20 are screwed together.
