In another embodiment, the cover 122 may include an upper cover and a lower cover assembled together. A lid seal ring 124 is positioned over the lower end of lid 122, and lid seal ring 124 seals the gap between lid 122 and bowl assembly 101. The cover 122 is provided with a central cover mounting hole 125 communicating with the cup cavity 110. The central cover mounting hole 125 may be provided in a central region of the cover body 122 or offset from the central region of the cover body 122.

The center cap 123 is mounted in the center cap mounting hole 125 of the cap body 122 to protrude upward from the cap body 122. The center cover 123 is detachably attached to the cover body 122. The bottom end of the center cap 123 may be fitted with a center cap seal 126 to seal the gap between the center cap 123 and the cap body 122. In one embodiment, center cap 123 includes an upper center cap 127 and a lower center cap 128 assembled to upper center cap 127. The center cap 123 includes a retainer 129 and an elastic member 130.

In one embodiment, cap assembly 102 includes a ball valve relief assembly 131 assembled to cap 120. In the illustrated embodiment, the ball valve pressure relief assembly 131 is assembled within the central cap 123. In one embodiment, the ball valve pressure relief assembly 131 is removably assembled within the central cap 123. The upper center cap 127 and lower center cap 128 may be opened so that the ball valve relief assembly 131 may be removed for cleaning.

The ball valve pressure relief assembly 131 includes a seal 132 assembled to the cap 120 and a ball valve 133 received in the seal 132. The sealing member 132 is made of a soft material, such as silicone rubber, etc. The seal 132 is sealingly assembled with the central cap 123. In some embodiments, the seal 132 is removably assembled to the center cap 123. The seal 132 includes an inlet 134 and at least one outlet 135. The inlet port 134 communicates with the cup cavity 110 and the outlet port 135 communicates with the inlet port 134.

Fig. 5 shows an enlarged view of the part region 11 shown in fig. 4. Referring to fig. 4 and 5, the cap 120 is provided with an exhaust hole 140, and the negative pressure relief mechanism 121 is provided on the cap 120. When the air pressure in the cup cavity 110 is not lower than the external air pressure outside the food processor 100, the negative pressure relief mechanism 121 seals the vent hole 140, so that the cup cavity 110 is sealed. When the air pressure in the cup cavity 110 is lower than the external air pressure, the negative pressure relief mechanism 121 opens the vent hole 140 to communicate the cup cavity 110 with the outside through the vent hole 140, so that the air pressure in the cup cavity 110 is close to or the same as the external air pressure, the problem that the cover is difficult to open due to the negative pressure in the cup is solved, and the cover opening resistance is greatly reduced. When the air pressure in the cup cavity 110 is not lower than the external air pressure, the vent hole 140 can be sealed, so that the pressure in the cup cavity 110 can be maintained, and the vent hole 140 does not exhaust in a micro-pressure working state, thereby ensuring the pressure maintaining effect.

In some embodiments, one or more vents 140 may be provided. In some embodiments, the diameter D3 of the vent hole 140 ranges from 2mm to 5mm, allowing ambient air to quickly enter the cup when the vent hole 140 is open.

In some embodiments, the negative pressure relief mechanism 121 is disposed on at least one of the cover 122 and the central cover 123. In the embodiment shown in fig. 4 and 5, the negative pressure relief mechanism 121 is disposed on the cover 122. The negative pressure relief mechanism 121 seals or opens the vent hole 140. When the air pressure in the cup cavity 110 is not lower than the external air pressure outside the food processor 100, for example, when the food processor 100 operates at a low pressure, the vent hole 140 is sealed, and the cup cavity 110 is isolated from the outside, so that the cup cavity 110 is sealed. When the air pressure in the cup cavity 110 is lower than the external air pressure, i.e. the pressure in the cup is negative, the vent hole 140 is opened to communicate the cup cavity 110 with the outside.

In some embodiments, the negative pressure relief mechanism 121 includes a negative pressure relief valve that is movable relative to the vent 140 at least partially under the influence of air pressure. When the air pressure in the cup cavity 110 is not lower than the external air pressure, the negative pressure relief valve 121 covers and seals the exhaust hole 140 on the side of the cup cover 120 facing the cup cavity 110; when the air pressure in the cup cavity 110 is lower than the external air pressure, the negative pressure relief valve 121 opens the vent hole 140. The negative pressure relief valve 121 may be made of a soft material, such as silica gel, rubber, etc., and may deform under the action of air pressure to partially or wholly move relative to the cup cover 120. The negative pressure relief valve 121 covers the vent hole 140 on the side of the cup cover 120 facing the cup cavity 110, and when the air pressure in the cup cavity 110 is not lower than the outside air pressure, the air pressure in the cup cavity 110 pushes the negative pressure relief valve 121 against the cup cover 120, so that the negative pressure relief valve 121 is pressed against the cup cover 120, and the negative pressure relief valve 121 can be in interference fit with the cup cover 120 to seal the vent hole 140. When the air pressure in the cup cavity 110 is lower than the external air pressure, the negative pressure relief valve 121 moves into the cup cavity 110 under the action of the air pressure, and the exhaust hole 140 is opened. The negative pressure relief valve 121 has low cost, can automatically seal or open the vent hole 140 under the action of air pressure, thereby automatically realizing pressure relief under the condition of negative pressure in the cup, and covers the vent hole 140 when positive pressure in the cup, namely the air pressure in the cup is not lower than the external air pressure, thereby ensuring pressure maintaining in the cup and preventing the vent hole 140 from being blocked due to food entering.

In some embodiments, the cap 120 includes a mounting hole 141, and the negative pressure relief valve 121 includes a mounting portion 142 and a relief portion 143 extending from the mounting portion 142. The mounting portion 142 is mounted in the mounting hole 141, and the relief portion 143 extends from the mounting hole 141 toward the vent hole 140 beyond the vent hole 140 on a side of the lid 120 facing the cup cavity 110. The pressure relief portion 143 may move relative to the vent hole 140 under the gas pressure to seal or open the vent hole 140. In one embodiment, the mounting hole 141 is provided in the cover 122. The mounting hole 141 may be a through hole. The mounting portion 142 is fixedly held in the mounting hole 141. The relief 143 is located on a side of the cap 120 facing the cup cavity 110. When the air pressure in the cup cavity 110 is not lower than the external air pressure, the pressure relief portion 143 covers the vent hole 140, and seals the vent hole 140. When the air pressure in the cup cavity 110 is lower than the external air pressure, the external air pressure pushes the pressure relief portion 143 into the cup cavity 110, and the pressure relief portion 143 moves in the direction away from the vent hole 140 and tilts up, so that the vent hole 140 is opened to communicate the cup cavity 110 with the outside. The negative pressure relief valve 121 is simple to assemble, convenient to disassemble and clean, and simple in automatic sealing and pressure relief mode.

In one embodiment, the diameter of the mounting hole 141 ranges from 3mm to 8mm, facilitating assembly of the negative pressure relief valve 121. In one embodiment, the mounting portion 142 has a limiting portion 144 for limiting engagement with the cap 120. The maximum outer diameter D1 of the limiting part 144 is larger than the diameter D2 of the mounting hole 141, and the difference between the maximum outer diameter D1 of the limiting part 144 and the diameter D2 of the mounting hole 141 ranges from 1mm to 3 mm. So can be convenient for assemble, and can be spacing negative pressure relief valve 121 well. The pressure relief portion 143 is located on one side of the cap 120 facing the cup cavity 110, and the position-limiting portion 144 is located on the other side of the cap 120 opposite to the pressure relief portion 143. During assembly, the mounting portion 142 may be inserted into the mounting hole 141 from a side facing the cup cavity 110, and the stopper portion 144 may pass through the mounting hole 141. In one embodiment, the stopper portion 144 extends obliquely outward from a direction away from the pressure relief portion 143 to a direction close to the pressure relief portion 143, and may be similar to a head shape of mushroom, thus facilitating assembly.

In some embodiments, the negative pressure relief valve 121 is provided with a surrounding rib 146 protruding toward the cap 120, the surrounding rib 146 surrounds the exhaust hole 140, and when the negative pressure relief valve 121 seals the exhaust hole 140, the surrounding rib 146 is sealed and abutted against the cap 120. In one embodiment, relief portion 143 includes a circumferential rib 146 projecting toward cap 120 from a side facing cap 120. The surrounding rib 146 is abutted against the periphery of the exhaust hole 140 away from the mounting hole 141. When the air pressure in the cup cavity 110 is not lower than the external air pressure, the surrounding rib 146 is abutted to the cup cover 120 by the air pressure in the cup cavity 110, the surrounding rib 146 is abutted to the cup cover 120 in a sealing manner, and the air vent hole 140 can be sealed and the cup cavity 110 can be sealed in an interference fit manner. When the air pressure in the cup cavity 110 is lower than the external air pressure, the surrounding rib 146 is separated from the cup cover 120, and the exhaust hole 140 is opened. The arrangement of the surrounding ribs 146 can ensure that the sealing effect is better when positive pressure is generated in the cup. In one embodiment, the thickness W1 of the ribs 146 is in the range of 0.3mm to 1mm, which ensures better sealing effect under positive pressure in the cup.
