The cup cover component 6 covers the stirring cup 4, and the cup cover component 6 is provided with an exhaust port 7 communicated with the outside and an exhaust channel 8 communicated with the stirring cavity 5 and the outside through the exhaust port 7. In the process of making hot drinks, steam is generated in the stirring cavity 5, passes through the exhaust passage 8 and is exhausted outside through the exhaust port 7, so that the cup cover assembly 6 is conveniently opened, and scalding caused by gathering too much steam is prevented when the cup cover assembly 6 is opened.

The exhaust passage 8 includes a normally open passage 9. The normally open channel 9 is always in an open state, so that the stirring cavity 5 is always communicated with the exhaust port 7. In this embodiment, the exhaust port 7 is a normally open through hole for communicating the outside with the stirring chamber 5. That is, normally, when the exhaust port 7 is not blocked, the steam in the stirring chamber 5 is exhausted to the outside through the normally open passage 9.

In some embodiments, the lid assembly 6 includes an outer lid 10 and an inner lid 11 disposed inside the outer lid 10, the vent 7 penetrates the outer lid 10 and the inner lid 11, the vent 7 includes an inner vent 12 formed in the inner lid 11 and an outer vent 13 formed in the outer lid 10, the inner vent 12 communicates with the stirring chamber 5, the outer vent 13 communicates with the outside, and the normally-open channel 9 is a channel for hermetically communicating the inner vent 12 and the outer vent 13.

After the outer cap 10 and the inner cap 11 are assembled by extrusion, the periphery of the channel where the inner exhaust port 12 and the outer exhaust port 13 are communicated is in a sealed state, so as to prevent steam from being mixed, and the steam can only be discharged to the outside through the inner exhaust port 12 and the outer exhaust port 13 in sequence.

In some embodiments, cap assembly 6 further includes a vent seal ring 14, vent seal ring 14 surrounding the inner vent 12 and outer vent 13 at a location where they communicate and being sandwiched between outer cap 10 and inner cap 11. In this embodiment, the exhaust port sealing ring 14 is used to seal the gap between the positions where the inner exhaust port 12 and the outer exhaust port 13 meet, so as to ensure reliable sealing of the joint between the inner exhaust port 12 and the outer exhaust port 13, and prevent steam from leaking from the joint, thereby preventing steam in the stir chamber 5 from being mixed in the space except for the inner exhaust port 12 and the outer exhaust port 13, and improving the sealing effect. In some embodiments, the number of outside exhaust ports 13 includes, but is not limited to, 1, 2, 3, 4, etc.

In some embodiments, a first groove 15 disposed around the inner vent 12 is formed on a side surface of the inner cap 11 facing the outer cap 10, a first protrusion 16 disposed around the outer vent 13 is formed on a side surface of the outer cap 10 facing the inner cap 11, and the vent sealing ring 14 is disposed in the first groove 15 and is pressed and fixed in the first groove 15 by the first protrusion 16, so that the inner vent 12 is in sealed communication with the outer vent 13. In this embodiment, the first groove 15 is recessed away from the outer lid 10 such that the vent gasket 14 is embedded therein. The first projection 16 projects toward the inner lid 11 and faces the first recess 15. Thus, the vent gasket 14 is pressed into the first groove 15 by the first protrusion 16, and the positional stability and sealing reliability of the vent gasket 14 in the first groove 15 are ensured.

In some embodiments, the size of the first groove 15 matches the size of the vent seal ring 14. The size of the first protrusion 16 matches the size of the vent seal 14. In some embodiments, the cross-section of the first groove 15, the cross-section of the first protrusion 16, and the cross-section of the vent gasket 14 are U-shaped along a direction perpendicular to the height direction of the lid assembly 6.

In some embodiments, a side surface of the outer cap 10 facing the inner cap 11 is provided with a second groove (not shown) disposed around the outer vent 13, a side surface of the inner cap 11 facing the outer cap 10 is formed with a second protrusion (not shown) disposed around the inner vent 12, and the vent sealing ring 14 is disposed in the second groove and is pressed and fixed by the second protrusion in the second groove, so that the inner vent 12 is in sealed communication with the outer vent 13.

Thus, the exhaust port seal ring 14 is pressed in the second groove by the second protrusion, and the stability of the position of the exhaust port seal ring 14 in the second groove and the reliability of sealing are ensured. In this embodiment, the vent seal 14 is located on the outer lid 10. Thus, the outer peripheries of the inner exhaust port 12 and the outer exhaust port 13 are sealed, and the sealing diversity between the outer cover 10 and the inner cover 11 is also exhibited.

Fig. 3 is an assembled cross-sectional view of another embodiment of the lid assembly 6 of the food processor 1 shown in fig. 1. As shown in fig. 3, the exhaust passage 8 includes a pressure exhaust passage 100. The cap assembly 6 further comprises a pressure relief valve 18, the pressure vent passage 100 is connected with the pressure relief valve 18, and the pressure relief valve 18 opens the pressure vent passage 100 when the pressure in the stirring chamber 5 is greater than or equal to a threshold pressure, so that the stirring chamber 5 is communicated with the outside through the pressure vent passage 100, and closes the pressure vent passage 100 when the pressure is less than the threshold pressure, so as to seal the pressure vent passage 100. When the outer side exhaust port 13 is blocked, the generated steam is more and more generated along with the continuous heating of the food material in the stirring cavity 5, so that the pressure of the stirring cavity 5 is enhanced. At this time, when the pressure is increased to be greater than or equal to the threshold pressure, the relief valve 18 is opened to open the pressure exhaust passage 100 to communicate the stirring chamber 5 with the outside, so that the steam is discharged to the outside through the pressure exhaust passage 100, and when the normally open passage 9 is blocked, no other exhaust passage is used for exhausting, thereby reducing the potential safety hazard of exhausting. In addition, when the pressure in the stirring chamber 5 decreases to be less than the threshold pressure, the relief valve 18 closes to close the pressure exhaust passage 100, and there are two cases where the pressure in the stirring chamber 5 is less than the threshold pressure. In one case, the food material in the mixing chamber 5 is no longer heated, and the temperature of the mixing chamber 5 is reduced, so that the pressure in the chamber is gradually reduced to be less than the threshold pressure; alternatively, the outer exhaust port 13 is unblocked and some of the vapor can escape through the outer exhaust port 13, which also gradually reduces the chamber pressure to less than the threshold pressure. At this time, the pressure discharge passage 100 is automatically closed.

In some embodiments, the lid assembly 6 includes a lid body 17, the pressure relief valve 18 is disposed through the lid body 17, the pressure relief valve 18 includes a valve rod 19 and a valve rod gasket 20, the valve rod 19 includes a valve cavity 21 and a pressure exhaust port 22, the pressure exhaust port 22 is communicated with the valve cavity 21, the valve cavity 21 is communicated with the pressure exhaust passage 100, the valve rod gasket 20 is sleeved on the valve rod 19 and seals the pressure exhaust port 22, and the valve rod gasket 20 is configured to be jacked up when the pressure in the stirring cavity 5 is greater than or equal to a threshold pressure, so that the pressure exhaust port 22 is communicated with the outside. In this embodiment, a pressure exhaust port 22 is provided at the upper end of the valve stem 19. When the normally open passage 9 is not blocked, the pressure exhaust port 22 is covered by the stem packing 20 on the periphery, so that the pressure exhaust port 22 is sealed. When the normally open channel 9 is blocked, the pressure in the cavity is continuously increased along with the continuous increase of the steam in the stirring cavity 5. When the pressure is increased to be higher than the threshold pressure, the steam is enabled to fill the valve cavity 21, and thrust towards the outside of the cup cover body 17 is generated on the valve rod 19, and the thrust is larger than the sum of the gravity of the valve rod 19 and the valve rod sealing ring 20. Therefore, the valve rod sealing ring 20 is jacked up to enable the pressure exhaust port 22 to be communicated with the outside to exhaust, the pressure relief valve 18 can be kept relatively fixed with the cup cover body 17, the connecting structure of the pressure relief valve 18 connected with the cup cover body 17 is simplified, and the concept is ingenious. When the thrust force is smaller than the sum of the gravity of the stem 19 and the stem packing 20, the stem packing 20 is restored to seal the pressure exhaust port 22. It should be noted that the above-mentioned pressure vent 22 is an embodiment of the vent 7, and the pressure vent 22 is formed in the valve rod 19 and communicates with the valve cavity 21.

In some embodiments, cap body 17 includes mounting holes 23, and valve stem 19 is disposed through mounting holes 23 in cap body 17.

In some embodiments, the valve cavity 21 has a pore size a ranging from 1 mm to 50 mm. Therefore, the influence of the too large aperture of the valve cavity 21 on the effect of the pressure exhaust passage 100 is avoided, and the influence of the too large aperture of the valve cavity 21 on the size of the whole machine is avoided, which is not beneficial to the miniaturization structure of the whole machine.

In some embodiments, the stem gasket 20 is raised under pressure to a height b in the range of 1-20 mm. That is, the weight of the stem gasket 20 cannot be excessive, so that the stem gasket 20 is easily lifted. Thus, the valve rod sealing ring 20 is prevented from being jacked up to an excessive height to influence the overall size of the relief valve 18, which is not favorable for the miniaturization structure of the whole machine.

In some embodiments, the stem seal ring 20 is located outside the lid body 17, the upper end of the stem seal ring 20 abuts against the head of the stem 19, the lower end of the stem seal ring 20 abuts against the lid body 17, a gap 190 is provided between the lower end of the stem seal ring 20 and the stem 19 to seal the pressure exhaust port 22, and the lower end of the stem seal ring 20 is jacked up when the pressure in the stirring chamber 5 is greater than or equal to the threshold pressure. The upper end of the stem gasket 20 is a fixed end and is fixed to the head of the stem 19. The lower end of the valve rod sealing ring 20 is a movable end which is separable from the upper surface of the cup cover body 17. Specifically, when the valve rod sealing ring 20 is not jacked up, the lower end of the valve rod sealing ring is abutted against the upper surface of the cup cover body 17, and surrounds the periphery of the pressure exhaust port 22, so that a gap 190 is formed between the valve rod sealing ring and the valve rod 19, the gap 190 facilitates gas to enter and ensures that gas pressure effectively acts on the valve rod sealing ring 20, so that the valve rod sealing ring 20 is jacked up when the pressure is greater than or equal to threshold pressure, and exhaust is realized.

In some embodiments, the lower end of the stem gasket 20 flares away from the upper end and surrounds and covers the periphery of the pressure vent 22. In this way, the flexibility of the lower end of the stem gasket 20 can be increased, which is advantageous for deformation under the action of air pressure and for releasing the sealing of the pressure vent 22. In some embodiments, the lower end of the stem seal 20 is flared.

In some embodiments, the normally open channel 9 communicates the stirring chamber 5 with the exhaust port 7 (as shown in fig. 2), and the normally open channel 9 is a sealed channel, and the valve rod 19 is inserted through the normally open channel 9. That is, the pressure exhaust passage 100 and the normally open passage 9 have a common structure, so that the cap assembly 6 has a compact structure, and is beneficial to miniaturization. And the valve rod 19 is arranged in the sealed normally open channel 9 in a penetrating way, so that steam can be prevented from leaking to other parts of the cup cover assembly 6.

In some embodiments, cap assembly 6 further includes a vent seal 14 that seals the passage between stir chamber 5 and pressure vent 22. The lower end of the valve rod 19 penetrates through the exhaust port sealing ring 14 and is cast into an integrated structure with the exhaust port sealing ring 14 through an injection molding process. Therefore, the upper end of the valve rod 19 can be fixed with the cup cover body 17, and the lower end of the valve rod 19 can be fixed with the exhaust port sealing ring 14, so that the stability of the position of the valve rod 19 can be ensured, and smooth exhaust of the valve cavity 21 through the valve rod 19 is ensured.

Fig. 4 is an assembled sectional view of another embodiment of the lid assembly 6 of the food processor 1 shown in fig. 1. As shown in fig. 4, in some embodiments, vent passage 8 further comprises a manual vent passage 101. The cap assembly 6 is provided with a manual switch 24 for opening or closing the manual exhaust passage 101. In this embodiment, when the outer side exhaust port 13 of the exhaust port 7 is blocked and the food material in the stirring cavity 5 is continuously heated, more and more steam is generated to increase the pressure in the stirring cavity 5, so that the stem gasket 20 is pushed open, the head of the manual switch 24 (shown in fig. 3) is pressed to slide the manual switch 24 toward the lid body 17, and accordingly, the stem gasket 20 is also pressed toward the lid body 17. This causes the manual switch 24 to provide a negative pressure into the stir chamber 5. At this time, the steam at the outside exhaust port 13 is burst. Thus, the outside exhaust port 13 is communicated with the outside, and rapid exhaust and pressure relief of the manual exhaust passage 101 is realized.

In some embodiments, the manual switch 24 includes an elastic baffle 25, the exhaust port 7 is disposed on the lid body 17, the elastic baffle 25 includes a connecting end 29 and a free end 26, the connecting end 29 is fixedly connected to the lid body 17, the free end 26 is connected to the valve rod 19, the valve rod 19 is axially movably disposed relative to the lid body 17, the valve rod 19 drives the free end 26 to move down under the action of external force, the manual exhaust passage 101 is opened, and after the external force disappears, the free end 26 resets and closes the manual exhaust passage 101. In this embodiment, the lower end of the valve rod 19 extends into the cup lid body 17, and the elastic baffle 25 is penetrated through, so that the rod cavity 28 of the valve rod 19 is communicated with the stirring cavity 5. The free end 26 of the elastic retainer 25 can move up and down relative to the cup cover body 17. Specifically, when the outside gas vent 13 is blocked, and the valve rod 19 slides towards the cup cover body 17 under the combined action of the steam pressure of the stirring cavity 5 and the rod cavity 28, the top of the valve rod 19 has a certain length away from the upper surface of the cup cover body 17, so that the manual switch 24 is conveniently and manually pressed, and the valve rod 19 slides towards the stirring cavity 5. At this moment, the lower end of the valve rod 19 can drive the free end 26 to move downwards, so that the outer side exhaust port 13 is communicated with the outside, exhaust is realized, the structure is simple, the design is ingenious, and the pressure relief effect is good. And after the hand is released from the manual switch 24, the free end 26 is displaced upward to be restored by the elastic restoring force of the elastic shutter 25, so that the manual exhaust passage 101 is closed.

In some embodiments, pressing the manual switch 24 displaces the free end 26 downward by a stroke d in the range of 1-50 mm. So, avoid free end 26 downward displacement stroke d too big, and cause elastic baffle 25 too big, and then cause the too big problem of bowl cover subassembly 6, be unfavorable for the miniaturized structure of complete machine.

In some embodiments, valve stem 19 and resilient barrier 25 are cast as a unitary structure by an injection molding process. This ensures the stability of the connection of the valve rod 19 to the elastic shutter 25 and the reliable opening of the manual exhaust passage 101.

The valve rod 19 serves to form a structural component of the pressure discharge channel 100. The manual switch 24 is used to form a structural component of the manual air discharge passage 101. In some embodiments, valve stem 19 functions as manual switch 24. Therefore, the pressure exhaust channel 100 and the manual exhaust channel 101 share the same structural components, so that the whole structure of the cup cover assembly 6 is compact, and the miniaturization is facilitated.

Referring to fig. 2 and 4, in some embodiments, the normally open channel 9 is a sealed channel that hermetically connects the stirring chamber 5 and the exhaust port 7, and the free end 26 is disposed in the normally open channel 9. In other words, the manual exhaust channel 101 and the normally open channel 9 have a common part in structure, so that the overall structure of the cup cover assembly 6 is compact, and miniaturization is facilitated. And the elastic baffle plate 25 is arranged in the sealed normally open channel 9 in a penetrating way, so that steam can be prevented from leaking to other parts of the cup cover assembly 6.

In some embodiments, one end of the flexible barrier 25 is a connecting end 29, the connecting end 29 is connected to the vent gasket 14, and the other end of the flexible barrier 25 is a free end 26. So, elastic baffle 25 passes through link and gas vent sealing washer 14 fixed connection, realizes elastic baffle 25's location, and the relative bowl cover body 17 of free end 26 of avoiding elastic baffle 25 is dropped easily about the displacement to ensure elastic baffle 25's stability, and ensure to open manual exhaust passage 101 smoothly and exhaust.

In some embodiments, the resilient flap 25 is provided as a unitary structure with the vent seal 14. Therefore, the connection stability of the elastic baffle 25 and the exhaust port sealing ring 14 can be ensured, and the processing technology is simple and low in cost.

Fig. 5 is a bottom structure view of the lid assembly 6 of the food processor 1 shown in fig. 1. In some embodiments, as shown in fig. 1, 4 and 5, the cap body 17 includes a support rib 30 protruding toward the free end 26, and the support rib 30 contacts the free end 26. When the free end 26 is not pressed down, the support rib 30 supports the free end 26 to prevent the free end 26 from blocking the communication between the agitation chamber 5 and the air discharge port 7 in the free-fall state. One side of the support rib 30 back to the connecting end 29 is a first space 31, the first space 31 is communicated with the stirring cavity 5 and the exhaust port 7 all the time to form a normally open channel 9, one side of the support rib 30 facing the connecting end 29 is a second space 32, the second space 32 is communicated with the stirring cavity 5 and the exhaust port 7 when the manual switch 24 is pressed down to form a manual exhaust channel 101, and the elastic baffle 25 is separated from the support rib 30 when the manual exhaust channel 101 is in an open state. In the closed state of the manual exhaust passage 101, the elastic shutter 25 abuts against the support rib 30. The support rib 30 is surrounded by the first projection 16. That is, the space between the support rib 30 and the first projection 16 is a first space 31, and the first space 31 is a normally open space. When the exhaust port 7 is not blocked, the steam in the stirring chamber 5 is exhausted through the first space 31 and the exhaust port 7. When the first space 31 is blocked and the air pressure of the valve rod 19 in the stirring chamber 5 continuously rises and slides back to the stirring chamber 5, the manual switch 24 can be manually pressed down, so that the valve rod 19 drives the free end 26 to be pressed down, the free end 26 is separated from the support rib 30, and a space is formed between the two, and the space is a second space 32. And, valve rod 19 drives free end 26 and pushes down and produces the driving force towards stirring chamber 5 bottom, and according to the reaction force principle of power, this driving force makes the gas in stirring chamber 5 produce the apical force opposite with this driving force direction, can scatter the steam of gas vent 7 department through this apical force. In this way, the stirring chamber 5 is communicated with the exhaust port 7 through the second space 32, and at this time, the gas can flow from the second space 32 to the exhaust port 7 to be exhausted. This scheme pressure release exhaust effect is good, and structural design is simple ingenious, convenient operation.

In some embodiments, the height c of the first protrusion 16 along the height direction of the lid assembly 6 ranges from 1 mm to 30mm, so as to avoid the height c from being too high to affect the overall size of the lid assembly 6.
