Description

Technical Field

[0001] This utility model relates to the field of small household appliance technology, specifically to a valve body assembly, a cover assembly, and a cooking utensil. Background Technology

[0002] Pressure cooking appliances generally consist of a pot body and a lid. The lid body includes a liner and a locking mechanism, with locking teeth on the locking mechanism. During pressurized cooking, the lid body is connected to the pot body via these teeth. Simultaneously, an exhaust pipe, in conjunction with a pressure relief valve, allows for pressure release. Specifically, during cooking, food is placed into the pot body, the lid is installed, and the locking mechanism is rotated to engage the locking teeth. After cooking, the pressure is released through the exhaust pipe and pressure relief valve. Once pressure is released, the lid body is rotated to separate the locking teeth, allowing the lid to be opened.

[0003] In related technologies, to achieve rapid venting, a cavity and a sealing structure are typically provided on the cover. When rapid venting is required, a solenoid valve drives the sealing structure to open the cavity, thus enabling venting. After venting is complete, a resilient element resets the cover. The steam seat has an installation structure, with the resilient element positioned between the installation structure and the sealing structure. This arrangement makes the steam seat's structure relatively complex. Utility Model Content

[0004] The main objective of this invention is to provide a valve body assembly, a cover assembly, and a cooking appliance to solve the problem of the complex structure of steam seats in related technologies.

[0005] To achieve the above objectives, according to one aspect of the present invention, a valve body assembly is provided, comprising: a mounting base; a valve body, the valve body being mounted within the mounting base, the valve body having a cavity and a first opening communicating with the cavity and a plurality of second openings; a sealing structure, including a connecting rod and a plurality of sealing elements disposed on the connecting rod, the connecting rod being movably inserted into the plurality of second openings, the plurality of sealing elements being disposed in a one-to-one correspondence with the plurality of second openings; a mounting cylinder, mounted at one of the second openings; a driving member, drivingly cooperating with the connecting rod to drive the connecting rod to move the plurality of sealing elements and cause the sealing elements to avoid the second openings; and an elastic member, disposed between the mounting cylinder and the connecting rod and drivingly cooperating with the connecting rod, the elastic member enabling the sealing elements to remain in a position blocking the second openings.

[0006] The present invention relates to a valve body housed within a mounting base. The valve body has a cavity and a first opening communicating with the cavity, as well as multiple second openings. The sealing structure includes a connecting rod and multiple sealing elements mounted on the connecting rod. The connecting rod is movably disposed within the multiple second openings. Each sealing element corresponds to one of the multiple second openings. A mounting cylinder is installed at one of the second openings. An elastic element is disposed between the mounting cylinder and the connecting rod and drives the connecting rod. The elastic element allows the sealing element to remain in a position blocking the second opening. A driving element drives the connecting rod and allows the sealing element to avoid the second opening. With this configuration, when the driving element moves the connecting rod, it drives the sealing element to avoid the second opening, allowing fluid to drain through the second opening. When the driving element stops, the elastic element pushes the connecting rod to seal the second opening, preventing fluid from flowing out. Furthermore, since the mounting cylinder is mounted on the valve body and the elastic element drives the mounting cylinder, there is no need to install a structure to fix the elastic element on the mounting base, thus simplifying the overall structure of the mounting base. Therefore, the present invention effectively solves the problem of complex structures in related technologies for steam seats.

[0007] Furthermore, the mounting cylinder has an inner protrusion, the connecting rod has an outer protrusion, and the elastic element is positioned between the inner and outer protrusions. The two ends of the elastic element engage with the inner and outer protrusions respectively, thus, under the action of the inner and outer protrusions, the position of the elastic element becomes more stable.

[0008] Furthermore, the mounting cylinder includes a first cylindrical section and a second cylindrical section connected to the first cylindrical section. The diameter of the first cylindrical section is smaller than the diameter of the second cylindrical section. The first cylindrical section is inserted into a second opening, and the second cylindrical section is located outside the valve body. This configuration ensures a more stable position of the mounting cylinder on the valve body, and also provides some guidance for the connecting rod, thereby making the movement direction of the connecting rod more stable.

[0009] Furthermore, the valve body assembly also includes a push rod structure, which is movably mounted on the mounting base and located between the drive member and the connecting rod. The push rod structure's placement between the connecting rod and the drive member results in a larger distance between the drive member and the second opening. This ensures that when fluid exits from the second opening, the fluid will not significantly impact the drive member, thereby guaranteeing the stability of the drive member's operation.

[0010] Furthermore, the push rod structure includes a pusher top and a transmission part. A first connecting hole is provided on the mounting base, and the transmission part is movably inserted into the first connecting hole. The pusher top is located on the outside of the mounting base. This configuration simplifies the overall structure of the push rod and effectively achieves the transmission function.

[0011] Furthermore, a first stop block is provided on the push rod structure, and a second stop block is provided on the mounting base. The first and second stop blocks cooperate to prevent the push rod structure from separating from the mounting base. When the elastic element drives the connecting rod to move, it can drive the push rod structure to move away from the valve body. At this time, under the action of the first and second stop blocks, the push rod structure can be prevented from separating from the mounting base, thereby making the position of the push rod structure more stable.

[0012] Furthermore, the valve body assembly also includes a push rod seat, which is mounted on a mounting base. The push rod seat has a guide hole, and the push rod structure also includes a guide portion that is movably inserted into the guide hole. A first stop block is disposed on the guide portion. The movable placement of the guide portion within the guide hole makes the movement of the push rod structure more stable and the direction of movement more fixed.

[0013] Furthermore, the push rod seat is also provided with a second connecting hole, which corresponds to the first connecting hole. The valve body assembly also includes a sealing sleeve, the first end of which is fixed to the connecting rod, and the second end of which is fixed between the mounting base and the push rod seat. The sealing sleeve blocks the second opening and the driving component, thereby preventing the driving component from being affected by the fluid.

[0014] Furthermore, the mounting base is a steam mount, and / or the mounting base is provided with a connection hole, into which the valve body is installed. This configuration allows for greater stability of the valve body's position.

[0015] According to a second aspect of this utility model, a cover assembly is provided, including a valve body assembly, which is the valve body assembly described above. No other structures are required on the mounting base, which not only reduces the processing difficulty of the mounting base but also makes cleaning the mounting base easier. Therefore, the cover assembly having the valve body assembly also has the aforementioned advantages.

[0016] According to a third aspect of this utility model, a cooking utensil is provided, including a lid assembly, which is the lid assembly described above. The lid assembly described above is relatively easy to manufacture and clean; therefore, the cooking utensil having the lid assembly described above also has the aforementioned advantages.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0033] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0034] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0035] like Figure 1 , Figure 2 as well as Figures 4 to 6As shown, in Embodiment 1, the valve body assembly includes: a mounting base 10, a valve body 20, a sealing structure 30, a mounting cylinder 40, a driving member 50, and an elastic member 60. The valve body 20 is mounted within the mounting base 10 and has a cavity 21, a first opening 22 communicating with the cavity 21, and multiple second openings 23. The sealing structure 30 includes a connecting rod 31 and multiple sealing elements 32 disposed on the connecting rod 31. The connecting rod 31 is movably inserted into the multiple second openings 23, and the multiple sealing elements 32 are correspondingly arranged one-to-one with the multiple second openings 23. The mounting cylinder 40 is mounted at one of the second openings 23. The driving member 50 drives the connecting rod 31 to move the multiple sealing elements 32, causing the sealing elements 32 to avoid the second openings 23. The elastic member 60 is disposed between the mounting cylinder 40 and the connecting rod 31 and drives the connecting rod 31 to maintain the sealing elements 32 in a position blocking the second openings 23.

[0036] Using the technical solution of Embodiment 1, the valve body 20 is disposed within the mounting base 10. The valve body 20 has a cavity 21 and a first opening 22 communicating with the cavity 21 and multiple second openings 23. The sealing structure 30 includes a connecting rod 31 and multiple sealing elements 32 disposed on the connecting rod 31. The connecting rod 31 is movably disposed within the multiple second openings 23. The multiple sealing elements 32 and the multiple second openings 23 are disposed in a one-to-one correspondence. The mounting cylinder 40 is installed at one of the second openings 23. An elastic element 60 is disposed between the mounting cylinder 40 and the connecting rod 31 and drives and cooperates with the connecting rod 31. The elastic element 60 enables the sealing element 32 to be held in the position blocking the second opening 23. The driving element 50 drives and cooperates with the connecting rod 31 and enables the sealing element 32 to avoid the second opening 23. With the above configuration, when the driving member 50 drives the connecting rod 31 to move, it can drive the sealing member 32 to avoid the second opening 23, thereby allowing the fluid to be discharged through the second opening 23. When the driving member 50 stops driving, the elastic member 60 can push the connecting rod 31 to make the sealing member 32 block the second opening 23, thereby preventing the fluid from flowing out of the second opening 23. Furthermore, since the mounting cylinder 40 is set on the valve body 20, and the elastic member 60 is driven and cooperates with the mounting cylinder 40, there is no need to set a structure to fix the elastic member 60 on the mounting base 10, thus making the overall structure of the mounting base 10 simpler. Therefore, the technical solution of Embodiment 1 effectively solves the problem of the complex structure of the steam seat in the related art.

[0037] like Figure 2 , Figure 5 as well as Figure 6As shown, in Embodiment 1, the mounting cylinder 40 has an inner protrusion 41 inside, the connecting rod 31 has an outer protrusion 311, and the elastic member 60 is disposed between the inner protrusion 41 and the outer protrusion 311. The two ends of the elastic member 60 cooperate with the inner protrusion 41 and the outer protrusion 311 respectively, meaning that under the action of the inner protrusion 41 and the outer protrusion 311, the position of the elastic member 60 can be made more stable.

[0038] like Figure 2 , Figure 5 as well as Figure 6 As shown, in Embodiment 1, the mounting cylinder 40 includes a first cylindrical section 42 and a second cylindrical section 43 connected to the first cylindrical section 42. The diameter of the first cylindrical section 42 is smaller than the diameter of the second cylindrical section 43. The first cylindrical section 42 is inserted into a second opening 23, and the second cylindrical section 43 is located outside the valve body 20. This arrangement ensures that the mounting cylinder 40 is stably positioned on the valve body 20, and the mounting cylinder 40 also provides some guidance for the connecting rod 31, thereby making the movement direction of the connecting rod 31 more stable.

[0039] It should be noted that the second cylindrical section 43 has a shielding effect on the elastic element 60, thus preventing the user from touching it. That is, the end of the elastic element 60 away from the valve body 20 is flush with the end of the second cylindrical section 43 away from the valve body 20, or the end of the elastic element 60 away from the valve body 20 is located between the end of the second cylindrical section 43 away from the valve body 20 and the valve body 20.

[0040] like Figure 1 , Figure 3 , Figure 7 as well as Figure 8 As shown, in Embodiment 1, the valve body assembly further includes a push rod structure 70, which is movably disposed on the mounting base 10 and located between the drive member 50 and the connecting rod 31. The push rod structure 70 is positioned between the connecting rod 31 and the drive member 50, resulting in a larger distance between the drive member 50 and the second opening 23. This ensures that when fluid is discharged from the second opening 23, the fluid will not significantly affect the drive member 50, thereby guaranteeing the stability of the drive member 50's operation.

[0041] like Figure 3 and Figure 8 As shown, in Embodiment 1, the push rod structure 70 includes a push top 71 and a transmission part 72. A first connecting hole 11 is provided on the mounting base 10, and the transmission part 72 is movably inserted into the first connecting hole 11. The push top 71 is located on the outside of the mounting base 10. This configuration makes the overall structure of the push rod structure 70 relatively simple and effectively realizes the transmission function.

[0042] like Figure 3 and Figure 8As shown, in Embodiment 1, the cross-sectional area of ​​the push-top 71 is larger than the cross-sectional area of ​​the transmission part 72. This arrangement ensures that the drive member 50 drives the push-top 71, thereby reducing the need for high precision during assembly and simplifying the assembly process.

[0043] like Figure 3 , Figure 7 as well as Figure 8 As shown, in Embodiment 1, a first stop block 73 is provided on the push rod structure 70, and a second stop block 12 is provided on the mounting base 10. The first stop block 73 and the second stop block 12 cooperate to prevent the push rod structure 70 from separating from the mounting base 10. When the elastic element 60 drives the connecting rod 31 to move, it can drive the push rod structure 70 to move away from the valve body 20. At this time, under the action of the first stop block 73 and the second stop block 12, the push rod structure 70 can be prevented from separating from the mounting base 10, thereby making the position of the push rod structure 70 more stable.

[0044] Specifically, the bottom surface of the mounting base 10 is provided with a recess, and the second stop block 12 is formed by the edge of the recess facing the drive member 50, which can effectively reduce the thickness of the valve body assembly.

[0045] like Figure 3 , Figure 8 as well as Figure 9 As shown, in Embodiment 1, the valve body assembly further includes a push rod seat 80, which is mounted on the mounting base 10. The push rod seat 80 is provided with a guide hole 81. The push rod structure 70 also includes a guide portion 74, which is movably disposed within the guide hole 81. A first stop block 73 is disposed on the guide portion 74. The movable placement of the guide portion 74 within the guide hole 81 makes the movement of the push rod structure 70 more stable and the direction of movement more fixed.

[0046] Specifically, the guide hole 81 is a rectangular hole, and the guide portion 74 is a guide plate. The guide plate passes through the rectangular hole, which improves the guiding effect, enabling limiting in four directions: up, down, left, and right. A portion of the guide hole 81 is located below the mounting base 10, and the lower surface of the mounting base 10 and the guide hole 81 jointly guide the guide portion 74. The guide portion 74 is sandwiched between the guide hole 81 and the lower surface of the mounting base 10, thus ensuring the guiding effect.

[0047] like Figure 3 , Figure 8 as well as Figure 9As shown, in Embodiment 1, the push rod seat 80 is further provided with a second connecting hole 82, which corresponds to the first connecting hole 11. The valve body assembly also includes a sealing sleeve 90, with the first end of the sealing sleeve 90 fixed to the connecting rod 31 and the second end of the sealing sleeve 90 fixed between the mounting base 10 and the push rod seat 80. The sealing sleeve 90 blocks the second opening 23 and the driving member 50, thereby preventing the driving member 50 from being affected by the fluid.

[0048] like Figure 1 , Figure 4 as well as Figure 7 As shown, in Embodiment 1, the mounting base 10 is a steam base, and a connection hole 13 is provided on the mounting base 10, with the valve body 20 installed in the connection hole 13. The above arrangement enables the valve body 20 to be positioned more stably.

[0049] Specifically, in Embodiment 1, there are two second openings 23 and two sealing elements 32. The two sealing elements 32 and the two second openings 23 are arranged in a one-to-one correspondence. The two sealing elements 32 include an inner sealing element and an outer sealing element. The inner sealing element is disposed inside the cavity 21 and seals with the inner side of one second opening 23. The outer sealing element is disposed outside the cavity 21 and seals with the outer side of the other second opening 23. The area of ​​the second opening 23 corresponding to the inner sealing element is the first area S1, and the area of ​​the second opening 23 corresponding to the outer sealing element is the second area S2. The first area S1 and the second area S2 satisfy the condition: S1 > S2.

[0050] The fluid inside cavity 21 applies force to both the inner and outer seals simultaneously. When the seal blocks the second opening 23, the fluid can compress the inner seal, causing the outer seal to tend to move towards the inner seal, thus improving the sealing effect. Furthermore, since the first area S1 is larger than the second area S2, the force exerted by the fluid on the inner seal is greater than the force exerted by the fluid on the outer seal. As a result, under the force on the inner seal, the connecting rod 31 can pull the outer seal, allowing the outer seal to fit against the valve body 20, further enhancing the sealing effect. Since both the inner and outer seals are mounted on the connecting rod 31, and the inner and outer seals can move synchronously, when the seal 32 moves from blocking the second opening 23 to opening the second opening 23, the fluid can flow out from the gap between the outer seal and the corresponding second opening 23. At the same time, there is also a gap between the inner seal and the corresponding second opening 23, through which the fluid can flow out. When the seal continues to move, the resistance encountered by the seal 32 is small, that is, the movement of the sealing structure 30 is relatively easy.

[0051] When all seals 32 open the second opening 23, the distance between the inner seal and the corresponding second opening 23 is a first distance A1, and the distance between the outer seal and the corresponding second opening 23 is a second distance A2, wherein the first distance A1 and the second distance A2 satisfy: A1 < A2. With the above settings, when the valve body assembly switches from the open state to the closed state, the inner seal can first seal the corresponding second opening 23, and then the outer seal can seal the corresponding second opening 23. When the outer seal seals the corresponding second opening 23, the inner seal can deform. When the valve body assembly switches from the closed state to the open state, the inner seal resets, thus making the movement of the sealing structure easier.

[0052] It should be noted that the difference between Embodiment 2 and Embodiment 1 is that a magnetic connection structure is provided between the push rod structure 70 and the connecting rod 31.

[0053] Specifically, such as Figure 10 As shown, in Embodiment 2, a first magnetic element is provided on the push rod structure 70, and the first magnetic element can magnetically engage with the connecting rod 31.

[0054] It should be noted that the difference between Embodiment 2 and Embodiment 3 is that a second magnetic element is provided on the side of the connecting rod 31 facing the push rod structure 70.

[0055] Specifically, such as Figure 11 As shown, in Embodiment 3, the first magnetic component and the second magnetic component are magnetically coupled.

[0056] According to a second aspect of this application, a cover assembly is provided, such as Figure 12 As shown, this embodiment includes a valve body assembly, which is the valve body assembly described above. No other structures are required on the mounting base, which not only reduces the processing difficulty of the mounting base but also makes cleaning the mounting base easier. Therefore, the cover assembly having the valve body assembly also has the aforementioned advantages.

[0057] According to a third aspect of this application, a cooking utensil is provided, including a lid assembly, which is the lid assembly described above. The lid assembly described above is relatively easy to manufacture and clean; therefore, the cooking utensil having the lid assembly described above also has the aforementioned advantages.

[0058] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0059] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0060] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0061] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
