Among them, preferably, a vent hole may be provided on the cover body, so that the pressure relief after vacuum juice extraction can be performed through the cover body. Of course, the vent hole may also be provided on the barrel or the food processing cup.

In any of the above technical solutions, preferably, the pressure relief assembly includes: a pressure relief seat provided with at least one pressure relief hole, the pressure relief hole communicating with the air relief hole; A plug is installed on the pressure relief seat to seal or open the at least one pressure relief hole; a pressure relief cover is movably installed on the high pressure side of the pressure relief seat, toward the low pressure side of the pressure relief seat Press the pressure relief cap in the direction, the pressure relief cap can move in the direction of the low pressure side of the pressure relief seat, and drive the pressure relief plug in the direction of the high pressure side of the pressure relief seat, and open the at least A pressure relief hole to release the pressure relief cap, the pressure relief cap and the pressure relief plug can be automatically reset; wherein, the pressure relief plug is an elastic member.

In these technical solutions, the pressure relief assembly includes a pressure relief seat, a pressure relief plug and a pressure relief cover, wherein the pressure relief seat may be a part of the structure to be pressure relieved, for example, may be a juice cup of a vacuum juicer, Of course, a part of the feed cup, cover, etc., of course, the pressure relief seat can also be provided independently of the pressure relief structure, for example, the pressure relief seat can be detachably installed on the juice cup, feed cup, cover and other parts. Here, the pressure relief seat is used to install a pressure relief plug and a pressure relief cover, and to form a pressure relief channel, and one side of the pressure relief seat corresponds to the cavity requiring pressure relief, and the other side of the pressure relief seat corresponds to the external environment Setting, so when the pressure relief seat is specifically used, there will be a pressure difference between the two sides of the pressure relief seat, and the high pressure side of the pressure relief seat is the side with the higher pressure, that is, the side where the pressure relief seat corresponds to the atmosphere. Therefore, the high-pressure side is also the atmospheric side, and the low-pressure side of the pressure-relief seat is the side with lower pressure, that is, the side of the pressure-relief seat corresponding to the pressure-relieving cavity. Therefore, the low-pressure side can also be called negative pressure side. The pressure relief plug is installed at the pressure relief hole to open and seal the pressure relief hole, and the pressure relief cover is movably installed on the high pressure side of the pressure relief seat, so that the pressure relief cover can be pressed from the high pressure side to the low pressure side. The pressure relief cover moves toward the low pressure side. At the same time, when the pressure relief cap moves in the direction of the low pressure side of the pressure relief seat, the pressure relief plug can move in the direction of the high pressure side of the pressure relief seat under the action of the pressure relief cap, and open at least one pressure relief hole, that is, the program presses The pressure relief cap can move the pressure relief cap in the pressing direction and simultaneously drive the pressure relief plug to move in the direction opposite to the pressing direction, such as moving or deforming in the direction opposite to the pressing direction, so that at least one pressure relief hole can be opened, so When pressure relief is required, pressure relief can be performed by pressing the pressure relief cap. This type of pressure relief structure can make the pressure relief plug move to the high pressure side and realize the opening of the pressure relief hole during pressure relief, while the conventional button-type pressure relief structure mostly uses the button to drive the rubber plug to move or deform into the pressure relief hole. In order to achieve the opening of the pressure relief hole, the rubber plug of this structure needs to be moved or deformed inward by the elastic deformation of the spring, and the reset after the movement. In this way, the rubber plug must use a button to achieve pressure relief The opening and sealing of the hole, so the button needs to be directly connected and matched with the rubber plug, so that there is a certain correlation between the button and the rubber plug, so that the button and the rubber plug cannot be set independently, which will cause the button to fail The rubber plug fails, which makes the entire pressure relief structure invalid. In this technical solution, since the pressure relief plug does not need to move to the low-pressure side during pressure relief, under normal conditions, the pressure relief plug is not required to be compressed by the pressure relief cap, and the pressure relief plug does not require the help of the pressure relief cap. To reset, so that under normal circumstances, when the pressure relief cap is not pressed, the pressure relief plug and the pressure relief cap are independent of each other, there is no force interaction, the pressure relief plug can rely on gravity, deformation and the inside and outside of the pressure relief plug The pressure difference etc. seals the pressure relief hole by itself, which allows the pressure relief cap to exist independently of the pressure relief plug when the pressure is not relieved, that is, the interaction between the pressure relief cap and the pressure relief plug is relieved, so that during use Regardless of whether the pressure relief cap fails, the pressure relief plug can seal the pressure relief hole, which can avoid the failure of the entire pressure relief component due to the failure of the pressure relief cap, thereby reducing the probability of product failure. At the same time, when the structure is in a normal state, the pressure relief plug is not subject to the force of the pressure relief cover. It does not need to rely on the pressure relief cover to seal the pressure relief hole, that is, it can rely on itself to seal the pressure relief hole. For the conventional spring button pressure relief structure, after the product is evacuated, the pressure difference between the internal and external pressure relief structures directly acts on the spring. Therefore, the spring also needs to overcome the pressure difference between the internal and external pressure relief structures. It is necessary to have a large compression state in order to be able to provide sufficient force to overcome the difference between internal and external pressures. On the one hand, the structure such as springs will be easily damaged due to long-term compression, and on the other hand, when pressure relief is required, the user also A large force is required to overcome the elastic force of the spring, thereby opening the pressure relief hole for pressure relief, which makes the opening of the pressure relief assembly very laborious, thereby reducing the user experience. There is also this type of relief plug that directly seals the relief hole, so after the product is evacuated, atmospheric pressure and negative pressure can directly act on the relief plug, so that atmospheric pressure and negative pressure will form on both sides of the relief plug Due to the pressure difference, the pressure relief plug can further form a seal with the pressure relief seat under the effect of the pressure difference, thereby improving the sealing effect of the pressure relief plug. In addition, in this structure, the combination of the pressure relief seat, the pressure relief cap and the pressure relief plug can form a button type structure, and the button type switch The operating feel is often better than that of a separate rubber plug, which makes the overall appearance and operating feel of the entire pressure relief component better, which can improve the sense of grade of the product and improve the user experience, which can improve the product's experience. Market Competitiveness.

Specifically, for example, the pressure relief plug is made of silicone or rubber. In addition, the pressure relief plug is an elastic piece, so that after pressure relief, the pressure relief plug can also be reset by its own elastic deformation, so that it does not need to be reset by the pressure relief cap, which can reduce the pressure relief plug and the pressure relief cap The interrelationship between them, so that the pressure relief plug can independently seal the pressure relief hole.

In any of the above embodiments, preferably, as shown in FIGS. 34 to 44, the pressure relief assembly 9 includes: a pressure relief seat 90 provided with at least one pressure relief hole 902 on the pressure relief seat 90, and The relief hole 82 communicates; the relief plug 92 is installed on the relief seat 90 to seal or open at least one relief hole 902; the relief cap 94 is movably installed on the high pressure side of the relief seat 90 to relieve pressure The low-pressure side of the seat 90 presses the pressure-relief cover 94, and the pressure-relief cover 94 can move toward the low-pressure side of the pressure-relief seat 90, and drive the pressure-relief plug 92 to move toward the high-pressure side of the pressure-relief seat 90, and open at least one relief The pressure hole 902 releases the pressure relief cap 94, and the pressure relief cap 94 and the pressure relief plug 92 can be automatically reset; wherein, the pressure relief plug 92 is an elastic member.

In these embodiments, the pressure relief assembly 9 includes a pressure relief seat 90, a pressure relief plug 92, and a pressure relief cover 94, wherein the pressure relief seat 90 may be part of the structure to be pressure relieved, for example, may be a vacuum juicer Part of the juicer cup, feeder cup, cover 8, etc. Of course, the pressure relief seat 90 can also be provided independently of the pressure relief structure, for example, the pressure relief seat 90 can be detachably mounted to the juicer cup, feeder cup , Cover 8 and other parts. Here, the pressure relief seat 90 is used to install the pressure relief plug 92 and the pressure relief cover 94, and to form a pressure relief channel, and one side of the pressure relief seat 90 is provided corresponding to the cavity requiring pressure relief, and the other side of the pressure relief seat 90 One side corresponds to the external environment. Therefore, when the pressure relief seat 90 is specifically used, there will be a pressure difference between the two sides of the pressure relief seat 90, and the high pressure side of the pressure relief seat 90 is the side with the higher pressure, that is, the pressure relief The seat 90 corresponds to the side where the atmosphere is installed, so the high pressure side is also the atmosphere side, and the low pressure side of the pressure relief seat 90 is the side with lower pressure, that is, the pressure relief seat 90 corresponds to the side of the chamber to be relieved of pressure Therefore, the low-pressure side can also be called the negative-pressure side. The pressure relief plug 92 is installed at the pressure relief hole 902 to open and seal the pressure relief hole 902, and the pressure relief cap 94 is movably installed at the high pressure side of the pressure relief seat 90, so that the pressure is released from the high pressure side to the low pressure side The cover 94 can move the pressure relief cover 94 toward the low pressure side. At the same time, when the pressure relief cap 94 moves in the direction of the low pressure side of the pressure relief seat 90, the pressure relief plug 92 can move in the direction of the high pressure side of the pressure relief seat 90 under the action of the pressure relief cap 94, and open at least one pressure relief hole 902 , That is, pressing the pressure relief cap 94 in this solution can move the pressure relief cap 94 in the pressing direction and simultaneously drive the pressure relief plug 92 to move in the direction opposite to the pressing direction, such as moving or deforming in the direction opposite to the pressing direction, thereby At least one pressure relief hole 902 can be opened, so that when pressure relief is required, the pressure relief cap 94 can be pressed to relieve pressure. This type of pressure relief structure can cause the pressure relief plug 92 to move toward the high pressure side when the pressure is relieved, and realize the opening of the pressure relief hole 902, while the conventional button-type pressure relief structure mostly drives the rubber plug into the pressure relief hole 902 through the button Movement or deformation to achieve the opening of the pressure relief hole 902, and the rubber plug of this structure needs to be moved or deformed inward by the elastic deformation of the spring, and the reset after the movement, so on the one hand the rubber plug must be able to use a button to be able to To realize the opening and sealing of the pressure relief hole 902, the button needs to be directly connected and cooperated with the rubber plug, so that there is a certain correlation between the button and the rubber plug, so that the button and the rubber plug cannot be set independently. When it fails, it will cause the rubber plug to fail, which will cause the entire pressure relief structure to fail. In this embodiment, since the pressure relief plug 92 does not need to move to the low pressure side during pressure relief, under normal conditions, the pressure relief plug 92 is not required to be compressed by the pressure relief cap 94, and the pressure relief plug 92 is also unnecessary. Reset by means of the pressure relief cap 94, so that under normal circumstances, when the pressure relief cap 94 is not pressed, the pressure relief plug 92 and the pressure relief cap 94 are independent of each other, there is no force interaction, the pressure relief plug 92 can rely on Gravity, deformation and pressure difference between the internal and external pressure relief plug 92 automatically seal the pressure relief hole 902, which allows the pressure relief cap 94 to exist independently of the pressure relief plug 92 when the pressure is not relieved, that is, the pressure relief cap 94 is removed from The interaction between the pressure relief plug 92, so that regardless of whether the pressure relief cap 94 fails during use, the pressure relief plug 92 can seal the pressure relief hole 902, so that the entire pressure relief due to the failure of the pressure relief cap 94 can be avoided The failure of component 9 occurs, thereby reducing the probability of product failure. At the same time, when the structure is in a normal state, the pressure relief plug 92 is not subject to the force of the pressure relief cover 94, and it does not need to rely on the pressure relief cover 94 to seal the pressure relief hole 902, that is, it can rely on itself to realize the pressure relief hole 902 For the conventional spring button type pressure relief structure, after the product is evacuated, the internal and external pressure difference of the pressure relief structure directly acts on the spring. Therefore, the spring also needs to overcome the internal and external pressure difference of the pressure relief structure, so In the actual process, the spring needs to have a large compression state in order to provide enough force to overcome the difference between the internal and external pressures. On the one hand, the spring and other structures will be easily damaged due to long-term compression, and on the other hand, they need to be released.
