Optionally, referring to fig. 6, the pressure equalizing valve 160 includes an elastic pushing and pulling member 161. The elastic pushing and pulling member 161 includes an elastic plugging portion and a pushing and pulling portion connected to each other, the elastic plugging portion plugs the pressure equalizing port 125, the pushing and pulling portion is located outside the pressure equalizing port 125, and pushing or pulling the pushing and pulling portion can deform the elastic plugging portion to communicate the inside and outside of the pressure equalizing port 125. The pressure equalizing valve 160 of the present embodiment utilizes the elasticity of the elastic pushing and pulling member 161 to generate deformation, so as to connect the inside and the outside of the pressure equalizing port 125; meanwhile, the elastic pushing and pulling piece 161 is reset by the elasticity of itself, and the pressure equalizing port 125 is restored to the elastic plugging part. The elastic push-pull member of the present embodiment may be configured to push the elastic push-pull member 161 to open the pressure equalizing port 125 or stretch the elastic push-pull member 161 to open the pressure equalizing port 125 according to the position of the pressure equalizing port 125 and the design requirement.
As shown in fig. 6, the elastic plugging portion of the elastic pushing-pulling member 161 of the present embodiment is a protruding structure on the elastic pushing-pulling member, the protruding structure is pressed against the pressure equalizing opening 125 by the elasticity of the elastic pushing-pulling member itself, when the pushing-pulling portion outside the pressure equalizing opening is pushed, the protrusion is released from the pressure equalizing opening 125, so that the pressure inside and outside the pressure equalizing opening are communicated, and the pressure inside and outside the cup cover is the same, which is convenient for opening the cup cover.
With continued reference to fig. 7, another embodiment of a pressure equalizing valve 160 is provided. The pressure equalizing valve 160 includes a restoring member 162 and a push-pull member 163. The push-pull member 163 includes a blocking portion 1631 and a push-pull portion 1632 connected to each other, the push-pull portion 1632 penetrates through the pressure equalizing port 125, and the push-pull portion is located outside the pressure equalizing port 125, the reset member 162 presses the blocking portion 1631 against the pressure equalizing port 125, and the push-pull portion is pushed or pulled to drive the blocking portion 1631 to avoid the pressure equalizing port 125, so that the pressure equalizing port 125 is communicated inside and outside.
Optionally, with continued reference to fig. 7, the pressure equalizing valve 16 further includes a pressure equalizing sealing ring 164, and the pressure equalizing sealing ring 164 is sleeved on the push-pull member and abuts against the pressure equalizing port 125 to ensure the sealing performance of the pressure equalizing valve 160 when sealing the pressure equalizing port.
Optionally, the push-pull member 163 further includes a limiting portion 1633, when the push-pull member 163 is pressed or pulled to a position where the inside and the outside of the pressure equalizing port 125 can be communicated, the limiting portion 1633 of the push-pull member 163 is limited by the cup cover and cannot move continuously, so that the push-pull member 163 can be prevented from being separated from the pressure equalizing port.

Since the push-pull part of the push-pull part 163 needs to penetrate through the pressure equalizing port 125 and the push-pull part is located outside the pressure equalizing port 125, and at the same time, the inside and the outside of the pressure equalizing port 125 need to be communicated after the blocking part leaves the pressure equalizing port, the outer diameter of the push-pull part is smaller than the inner diameter of the pressure equalizing port 125, and the push-pull part 163 can be prevented from deflecting when the push-pull part is pushed and pulled by arranging the guide part.
The vacuum cup lid 100, the vacuum cup and the vacuum blender/grinder cup provided by the present invention are further described below through the use process of the vacuum cup lid 100.
When a vacuum is drawn using the vacuum cap, the vacuum cap 100 is first coupled to the cup 200 via the coupling portion 123.
An external force is applied to the upper cover assembly 110, the piston 130 moves downwards in the piston cylinder 140 by overcoming the elastic force of the elastic member 150, the first air suction one-way valve 143 is closed under the action of pressure difference, the first air exhaust one-way valve 135 is opened, air in the vacuum chamber between the piston 130 and the piston cylinder 140 is exhausted into the hollow structure of the piston 130 through the first air exhaust one-way valve 135, and further enters the space between the outer wall of the piston 130 and the upper outer peripheral wall 112 through the air exhaust groove 133 at the top of the piston 130, and then is exhausted out of the vacuum cup cover 100. As the piston 130 moves downward, the volume in the evacuation chamber gradually decreases until the first exhaust valve seat 134 at the bottom wall of the piston 130 engages the first intake valve seat 142 at the bottom wall of the piston cylinder 140, the volume of the evacuation chamber decreases to substantially zero, and the process configuration compresses. When the external force applied to the lid assembly 110 is removed, the lid assembly 110 moves upward under the action of the elastic member 150, the volume of the vacuum pumping chamber gradually increases and negative pressure is formed, the first air suction check valve 143 is opened, and the first air discharge check valve 135 is closed. The air in the container enters the vacuum chamber through the first suction check valve 143 until the expansion of the elastic member 150 is finished, thereby completing an air suction cycle. The external force is applied again to the upper cap assembly 110, and the process is repeated until the container reaches the required vacuum degree, thereby achieving the purpose of vacuumizing the container. In each air extraction cycle, the air in the vacuum-pumping cavity is completely discharged, so that the air extraction efficiency is greatly improved.
After the container reaches the required vacuum degree, the piston 130 can be pressed to the bottommost point and then the upper cover assembly 110 is rotated, so that the top of the guide rib is abutted to the lower part of the flange structure, the upper cover assembly 110 is prevented from moving upwards under the action of the elastic piece 150, and therefore the foot bath compression state of the upper cover assembly 110 is maintained, and the container is convenient to store.
When the vacuum cup is opened to take out food, the pressure equalizing valve 160 is pulled to avoid the pressure equalizing port 125, so that the external air enters the container through the pressure equalizing port 125, and the vacuum cup cover 100 is taken down from the cup body 200.
Before the stirring/crushing work is carried out by utilizing the vacuumizing stirring/crushing cup, the stirring/crushing cup can be vacuumized to reduce air in the stirring/crushing cup so as to prevent food from being oxidized in the stirring/crushing process. Because gas is possibly generated in the stirring/crushing process, after the stirring/crushing process is finished, the vacuumizing cup cover 100 can be used for vacuumizing again.
