Description

Technical Field

[0001] This utility model relates to the field of small household appliance technology, specifically to a valve body structure, 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 valve chamber and a sealing structure are typically provided on the cover. When rapid venting is required, the solenoid valve drives the sealing structure to open the valve chamber, thereby enabling venting. Due to the influence of gravity, the position of the sealing structure is prone to skew, which can lead to misalignment between the solenoid valve and the sealing structure, resulting in instability when the solenoid valve drives the sealing structure to move. Utility Model Content

[0004] The main purpose of this utility model is to provide a valve body structure, a cover assembly, and a cooking appliance to solve the problem of misalignment between the solenoid valve and the sealing structure in related technologies.

[0005] To achieve the above objectives, according to one aspect of the present invention, a valve body structure is provided, comprising: a mounting base having a connecting hole; an exhaust structure disposed on the mounting base having an exhaust hole; a sealing structure including a connecting structure and a sealing element disposed on the connecting structure, the sealing element corresponding to the exhaust hole, the connecting structure being movably disposed within the connecting hole and the exhaust hole; a guide seat having a guide hole disposed on the mounting base, the guide hole corresponding to the connecting hole, the connecting structure being disposed within the guide hole; and a reset element disposed between the connecting structure and the exhaust structure to hold the sealing element in a position blocking the exhaust hole.

[0006] The present invention utilizes a mounting base with a connecting hole, an exhaust structure mounted on the mounting base, and an exhaust hole. The sealing structure includes a connecting structure and a sealing element mounted on the connecting structure, with the connecting structure movably inserted into the connecting hole and the exhaust hole. A guide seat has a guide hole, mounted on the mounting base, with the guide hole and connecting hole corresponding to each other, and the connecting structure inserted into the guide hole. A reset element is positioned between the connecting structure and the exhaust structure. Through this arrangement, when exhaust is required, the connecting structure is driven to move, causing the sealing element to move away from the exhaust hole, allowing steam to exit through the exhaust hole. Simultaneously, the guide hole on the guide seat guides the connecting structure, making its position more stable and ensuring alignment between the connecting structure and the driving element. Therefore, the present invention effectively solves the problem of misalignment between the solenoid valve and the sealing structure in related technologies.

[0007] Furthermore, the guide seat includes a first seat body and a second seat body, with a guide hole disposed between the first seat body and the second seat body. The guide seat is a split structure; when the first seat body and the second seat body are separated, the connecting structure can be installed in the guide hole; after the first seat body and the second seat body are assembled, the connecting structure can be effectively fixed.

[0008] Furthermore, the guide hole includes a first half-hole and a second half-hole. The first half-hole is disposed on a first base body, and the second half-hole is disposed on a second base body. The first base body is provided with a first extending protrusion located on the outer periphery of the first half-hole, and the second base body is provided with a second extending protrusion located on the outer periphery of the second half-hole. The aforementioned first and second extending protrusions have simple structures, are easy to install, and can extend the length of the guide hole, thereby improving the guiding effect on the connecting structure.

[0009] Furthermore, the first seat has a recessed portion, and the second seat is disposed within the recessed portion. The placement of the second seat within the recessed portion ensures greater stability in its position, thereby guaranteeing the guiding effect of the guide hole on the connecting structure.

[0010] Furthermore, a positioning structure is provided between the first and second seats. The positioning structure ensures the relative position between the first and second seats and prevents misalignment between them.

[0011] Furthermore, the positioning structure includes a positioning notch and a positioning protrusion that fit together, one of which is located on the first base body, and the other on the second base body. Alternatively, the positioning structure also includes a positioning hole and a positioning post, one of which is located on the first base body, and the other on the second base body. The positioning protrusion and positioning notch have a relatively simple structure, are easy to install, and can effectively achieve the positioning function. Simultaneously, the positioning post and positioning hole also enable positioning of the first and second base bodies, further ensuring a relatively stable relative position between them.

[0012] Furthermore, the guide hole includes a first half-hole and a second half-hole. The first half-hole is disposed on the first seat, and the second half-hole is disposed on the second seat. The opening of the first half-hole communicates with the recessed portion. A positioning structure is provided between the first and second seats. The positioning structure includes a positioning notch and a positioning protrusion for interlocking. The positioning notch is disposed on the recessed portion, and the positioning protrusion is disposed on the second seat. This arrangement allows the positioning notch to avoid the first half-hole, thereby facilitating the assembly of the connecting structure with the guide seat.

[0013] Furthermore, the second seat is located between the first seat and the mounting base. This arrangement allows the second seat to be sandwiched between the first seat and the mounting base, thereby making the position of the second seat more stable.

[0014] Furthermore, the connecting structure includes a first connecting rod and a second connecting rod, with a seal disposed on the first connecting rod. The first connecting rod is movably inserted into the discharge hole, and the second connecting rod is movably inserted into the connecting hole. Movement of the second connecting rod can drive movement of the first connecting rod. The second connecting rod extends the distance between the discharge hole and the driving component, thereby preventing the fluid discharged from the discharge hole from affecting the driving component, thus making the driving process of the driving component more stable.

[0015] Furthermore, the second connecting rod includes a rod body, a stop portion disposed on the rod body, and a push head. The push head is located at the end of the rod body, and there is a gap between the stop portion and the push head. A guide seat is located between the stop portion and the push head. The stop portion prevents the second connecting rod from separating from the mounting base, that is, it prevents the second connecting rod from passing through the connecting hole. The push head makes it easier to drive the driving component.

[0016] Furthermore, the valve body structure also includes a sealing sleeve. The first end of the sealing sleeve is fixed to the second connecting rod, and the second end of the sealing sleeve is clamped between the mounting seat and the guide seat. The sealing sleeve prevents fluid from flowing from the connecting hole to the outside of the mounting seat, and the clamping of the second end of the sealing sleeve between the mounting seat and the guide seat makes the position of the sealing sleeve more stable and the sealing effect better.

[0017] Furthermore, the exhaust structure includes an exhaust pipe and a guide cylinder. The guide cylinder is mounted on the exhaust pipe, the discharge port is located on the guide cylinder, and the reset component is positioned between the guide cylinder and the first connecting rod. The guide cylinder effectively fixes the reset component and makes its position more stable.

[0018] Furthermore, the guide cylinder has an inner protruding edge, the first connecting rod has an outer protruding edge, and the reset element is positioned between the inner and outer protruding edges. The two ends of the reset element engage with the inner and outer protruding edges respectively, thus, under the action of the inner and outer protruding edges, the position of the reset element becomes more stable.

[0019] According to a second aspect of this utility model, a cover assembly is provided, including a valve body structure, wherein the valve body structure is as described above. The valve body structure described above enables the connection structure to be more stable in position and less prone to misalignment with the driving component; therefore, the cover assembly having the valve body structure described above also has the aforementioned advantages.

[0020] According to a third aspect of this utility model, a cooking appliance is provided, including a lid assembly, which is the lid assembly described above. The valve body structure in the lid assembly described above has good driving stability and is less prone to misalignment between the connecting structure and the driving component. Therefore, the cooking appliance having the lid assembly described above also has the aforementioned advantages. Attached Figure Description

[0036] like Figure 1 , Figure 2 as well as Figure 8 As shown, in this embodiment, the valve body structure includes: a mounting base 10, an exhaust structure 20, a sealing structure 30, a guide seat 40, a reset member 50, and a driving member 60. The mounting base 10 has a connecting hole 11. The exhaust structure 20 is mounted on the mounting base 10 and has a discharge hole 21. The sealing structure 30 includes a connecting structure 31 and a sealing member 32 mounted on the connecting structure 31. The sealing member 32 corresponds to the discharge hole 21, and the connecting structure 31 is movably inserted into the connecting hole 11 and the discharge hole 21. The guide seat 40 has a guide hole 41, and is mounted on the mounting base 10. The guide hole 41 corresponds to the connecting hole 11, and the connecting structure 31 is inserted into the guide hole 41. The reset member 50 is disposed between the connecting structure 31 and the exhaust structure 20 to hold the sealing member 32 in a position that blocks the discharge hole 21.

[0037] Applying the technical solution of this embodiment, the mounting base 10 is provided with a connecting hole 11, and the exhaust structure 20 is provided on the mounting base 10, with an exhaust hole 21. The sealing structure 30 includes a connecting structure 31 and a sealing element 32 provided on the connecting structure 31, the connecting structure 31 being movably inserted into the connecting hole 11 and the exhaust hole 21. The guide seat 40 is provided with a guide hole 41, the guide seat 40 being provided on the mounting base 10, the guide hole 41 and the connecting hole 11 being correspondingly provided, and the connecting structure 31 being inserted into the guide hole 41. The reset element 50 is provided between the connecting structure 31 and the exhaust structure 20. With the above arrangement, when exhaust is required, the connecting structure 31 is driven to move, thereby causing the sealing element 32 to move away from the exhaust hole 21, so that steam can be discharged through the exhaust hole 21. At the same time, the guide hole 41 on the guide seat 40 can guide the connecting structure 31, thereby making the position of the connecting structure 31 more stable, that is, enabling the connecting structure 31 to be aligned with the driving element 60. Therefore, the technical solution of this embodiment effectively solves the problem that the solenoid valve and the sealing structure are prone to misalignment in related technologies.

[0038] Specifically, mounting base 10 is a steam mount.

[0039] In this embodiment, the valve body structure further includes a drive member 60, which drives the connecting structure 31 to move the connecting structure 31 and move the sealing member 32 away from the discharge port 21. The drive member 60 includes a solenoid valve, an electric actuator, a manual knob, a manual push button, or other drive structures.

[0040] like Figure 2 , Figure 4 as well as Figure 5 As shown, in this embodiment, the guide seat 40 includes a first seat body 42 and a second seat body 43, and a guide hole 41 is disposed between the first seat body 42 and the second seat body 43. The guide seat 40 is a split structure. When the first seat body 42 and the second seat body 43 are separated, the connecting structure 31 can be installed in the guide hole 41. After the first seat body 42 and the second seat body 43 are assembled, the connecting structure 31 can be effectively fixed.

[0041] like Figure 2 , Figure 4 as well as Figure 5As shown, in this embodiment, the guide hole 41 includes a first half-hole 411 and a second half-hole 412. The first half-hole 411 is disposed on the first seat 42, and the second half-hole 412 is disposed on the second seat 43. The first seat 42 is provided with a first extending protrusion 421 located on the outer periphery of the first half-hole 411. The second seat 43 is provided with a second extending protrusion 431 located on the outer periphery of the second half-hole 412. The aforementioned first extending protrusion 421 and second extending protrusion 431 have simple structures and are easy to install. Furthermore, the first extending protrusion 421 and second extending protrusion 431 can extend the length of the guide hole 41, thereby improving the guiding effect on the connecting structure 31.

[0042] like Figure 2 , Figure 4 as well as Figure 5 As shown, in this embodiment, the first seat 42 is provided with a recess 422, and the second seat 43 is disposed within the recess 422. The placement of the second seat 43 within the recess 422 makes the position of the second seat 43 more stable, thereby ensuring the guiding effect of the guide hole 41 on the connecting structure 31.

[0043] like Figure 2 , Figure 4 as well as Figure 5 As shown, in this embodiment, a positioning structure 44 is provided between the first seat 42 and the second seat 43. The positioning structure 44 ensures the relative position between the first seat 42 and the second seat 43, preventing misalignment between them.

[0044] like Figure 2 , Figure 4 as well as Figure 5 As shown, in this embodiment, the positioning structure 44 includes a positioning notch 441 and a positioning protrusion 442 that fit together. One of the positioning notch 441 and the positioning protrusion 442 is disposed on the first seat 42, and the other of the positioning notch 441 and the positioning protrusion 442 is disposed on the second seat 43. The positioning structure 44 also includes a positioning hole 443 and a positioning post 444. One of the positioning hole 443 and the positioning post 444 is disposed on the first seat 42, and the other of the positioning hole 443 and the positioning post 444 is disposed on the second seat 43. The structure of the positioning protrusion 442 and the positioning notch 441 is relatively simple, easy to set, and can effectively realize the positioning function. At the same time, the positioning post 444 and the positioning hole 443 can also realize the positioning of the first seat 42 and the second seat 43, which can further ensure that the relative position of the first seat 42 and the second seat 43 is relatively stable.

[0045] Preferably, such as Figure 2 , Figure 4 as well as Figure 5 As shown, in this embodiment, the guide hole 41 includes a first half-hole 411 and a second half-hole 412. The first half-hole 411 is disposed on the first seat 42, and the second half-hole 412 is disposed on the second seat 43. The opening of the first half-hole 411 communicates with the recess 422. A positioning structure 44 is provided between the first seat 42 and the second seat 43. The positioning structure 44 includes a positioning notch 441 and a positioning protrusion 442 for insertion and engagement. The positioning notch 441 is disposed on the recess 422, and the positioning protrusion 442 is disposed on the second seat 43. The above-mentioned arrangement allows the positioning notch 441 to avoid the first half-hole 411, thereby making the assembly of the connecting structure 31 and the guide seat 40 easier.

[0046] like Figure 2 , Figure 4 as well as Figure 5 As shown, in this embodiment, the second seat 43 is located between the first seat 42 and the mounting base 10. This arrangement ensures that the second seat 43 is sandwiched between the first seat 42 and the mounting base 10, thereby making the position of the second seat 43 more stable.

[0047] like Figures 1 to 3 as well as Figure 6 As shown, in this embodiment, the connecting structure 31 includes a first connecting rod 311 and a second connecting rod 312, and a sealing member 32 is disposed on the first connecting rod 311. The first connecting rod 311 is movably inserted into the discharge hole 21, and the second connecting rod 312 is movably inserted into the connecting hole 11. When the second connecting rod 312 moves, it can drive the first connecting rod 311 to move. The second connecting rod 312 extends the distance between the discharge hole 21 and the driving member 60, thereby preventing the fluid discharged from the discharge hole 21 from affecting the driving member 60, thus making the driving process of the driving member 60 more stable.

[0048] like Figure 6 As shown, in this embodiment, the second connecting rod 312 includes a rod body 3121, a stop portion 3122 and a push top 3123 disposed on the rod body 3121. The push top 3123 is located at the end of the rod body 3121, and there is a gap between the stop portion 3122 and the push top 3123. The guide seat 40 is located between the stop portion 3122 and the push top 3123. The stop portion 3122 can prevent the second connecting rod 312 from separating from the mounting base 10, that is, it can prevent the second connecting rod 312 from passing through the connecting hole 11. The push top 3123 can make it easier to drive the driving member 60.

[0049] Specifically, the cross-sectional area of ​​the push top 3123 is larger than that of the rod body 3121, and the push top 3123 has a plate structure. This makes it easier for the drive component 60 to cooperate with the push top 3123.

[0050] like Figure 1 , Figure 2 as well as Figure 7 As shown, in this embodiment, the valve body structure further includes a sealing sleeve 70. The first end of the sealing sleeve 70 is fixed to the second connecting rod 312, and the second end of the sealing sleeve 70 is clamped between the mounting base 10 and the guide seat 40. The sealing sleeve 70 can prevent fluid from flowing from the connecting hole 11 to the outside of the mounting base 10, and the second end of the sealing sleeve 70 is clamped between the mounting base 10 and the guide seat 40, which makes the position of the sealing sleeve 70 more stable and the sealing effect better.

[0051] like Figures 1 to 3 As shown, in this embodiment, the exhaust structure 20 includes an exhaust pipe 22 and a guide cylinder 23. The guide cylinder 23 is disposed on the exhaust pipe 22, the discharge hole 21 is located on the guide cylinder 23, and the reset member 50 is disposed between the guide cylinder 23 and the first connecting rod 311. The guide cylinder 23 can effectively fix the reset member 50 and make the position of the reset member 50 more stable.

[0052] like Figures 1 to 3 As shown, in this embodiment, the guide cylinder 23 has an inner protruding edge 231 inside, and the first connecting rod 311 has an outer protruding edge 3111. The reset member 50 is disposed between the inner protruding edge 231 and the outer protruding edge 3111. The two ends of the reset member 50 cooperate with the inner protruding edge 231 and the outer protruding edge 3111 respectively, that is, under the action of the inner protruding edge 231 and the outer protruding edge 3111, the position of the reset member 50 can be made more stable.

[0053] Specifically, in Embodiment 1, there are two discharge holes 21 and two sealing elements 32. The two sealing elements 32 and the two discharge holes 21 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 exhaust pipe 22 and seals with the inner side of one discharge hole 21. The outer sealing element is disposed outside the exhaust pipe 22 and seals with the outer side of the other discharge hole 21. The area of ​​the discharge hole 21 corresponding to the inner sealing element is the first area S1, and the area of ​​the discharge hole 21 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.

[0054] The fluid inside the exhaust pipe 22 exerts force on both the inner and outer seals simultaneously. When the seal 32 blocks the discharge hole 21, the fluid can squeeze 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 structure 31 can pull the outer seal, allowing the outer seal to fit against the exhaust pipe 22, further enhancing the sealing effect. Since both the inner and outer seals are mounted on the connecting structure 31, and the inner and outer seals can move synchronously, when the seal 32 moves from blocking the discharge hole 21 to opening the discharge hole 21, the fluid can flow out from the gap between the outer seal and the corresponding discharge hole 21. At the same time, there is also a gap between the inner seal and the corresponding discharge hole 21, through which the fluid can flow out. When the seal 32 continues to move, the resistance encountered by the seal 32 is small, that is, the movement of the sealing structure 30 is relatively easy.

[0055] According to a second aspect of this application, a cover assembly is provided, such as Figure 9 As shown, the cover assembly of this embodiment includes a valve body structure, which is the valve body structure described above. The valve body structure described above makes the position of the connecting structure 31 more stable and less prone to misalignment with the driving member 60. Therefore, the cover assembly with the valve body structure described above also has the aforementioned advantages.

[0056] According to a third aspect of this application, a cooking appliance is provided. The cooking appliance of this embodiment includes a lid assembly, which is the lid assembly described above. The valve body structure in the lid assembly has good driving stability and is less prone to misalignment between the connecting structure 31 and the driving member 60. Therefore, the cooking appliance having the lid assembly described above also has the aforementioned advantages.

[0057] The cooking appliance in this embodiment is an electric pressure cooker.

[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.
