[0005] The exhaust channel, buffer space and first exhaust hole in the embodiment of the present application are arranged in sequence from bottom to top along the axial direction of the exhaust pipe. The steam discharged from the exhaust pipe is discharged to the outside through the exhaust channel, buffer space and first exhaust hole in sequence, that is, the valve assembly provided in the embodiment of the present application realizes the function of exhausting upward.

At the same time, a second exhaust hole is provided on the valve cover, and the steam discharged from the accommodating cavity enters the buffer space through the second exhaust hole. The second exhaust hole is provided to extend the length of the exhaust channel, thereby playing a certain buffering role for the steam, which is conducive to reducing the possibility of rapid splashing of steam to the outside world and bringing safety hazards to users, thereby improving the safety of the use of the valve assembly. On the other hand, the valve seat provides a space for accommodating and exhausting the exhaust pipe. By fixing the valve seat and the valve cover together, it is conducive to improving the reliability of the entire valve assembly, so that the valve assembly can work normally and stably.

[0010] In a possible implementation manner, the first exhaust hole and the second exhaust hole are staggered.

[0011] Such a design is conducive to slowing down the flow rate of steam, that is, it plays a buffering role on the steam, reducing the possibility of strong steam splashing out from the first exhaust hole, thereby improving the safety of the valve assembly in use.

[0016] In a possible implementation manner, the valve seat has an abutment portion extending along its own radial direction toward a side away from the accommodating cavity, and along the axial direction of the exhaust pipe, the valve cover abuts against the abutment portion.

[0017] The abutment portion abuts against the valve cover to limit the valve cover, thereby improving the stability and reliability of the connection between the valve cover and the valve seat and reducing the possibility of the valve cover and the valve seat being separated from each other.

[0054] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0055] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0056] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0057] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0058] like Figures 1 to 3As shown, the embodiment of the present application provides a valve assembly 3, including an exhaust pipe 2, a valve body 31 and a valve cover 32. The valve body 31 is movably connected to one end of the exhaust pipe 2, wherein the valve body 31 includes an exhaust channel 311 and a valve core 312 located in the exhaust channel 311, one end of the exhaust pipe 2 is located in the exhaust channel 311, and the valve core 312 is used to block or open the exhaust pipe 2. The valve cover 32 is connected to the side of the valve body 31 away from the exhaust pipe 2, along the axial direction Z of the exhaust pipe 2, there is a buffer space 33 connected to the exhaust channel 311 between the valve body 31 and the valve cover 32, and the valve cover 32 is provided with a first exhaust hole 321 connected to the outside and the buffer space 33.

[0059] The exhaust pipe 2 can be installed on the container cover 10, and the container cover 10 can be the cover of the pressure cooker. The container cover 10 has a cover body 1, and the exhaust pipe 2 runs through the cover body 1 to connect the inside of the pressure cooker with the outside. The end of the exhaust pipe 2 is connected to the valve body 31. The exhaust channel 311 in the valve body 31 extends along the axial direction Z of the container cover 10 and is connected to the outside. The steam generated in the pressure cooker (not shown in the figure) can flow into the exhaust channel 311 through the exhaust pipe 2 and then be discharged to the outside. The valve body 31 can move relative to the exhaust pipe 2 along the axial direction Z of the container cover 10 to control the communication state between the exhaust channel 311 and the exhaust pipe 2, that is, to control the exhaust process of the pressure cooker. Specifically, the valve body 31 has a first working position and a second working position. When the valve body 31 is located at the first working position, the valve core 312 blocks the exhaust pipe 2, so that the exhaust pipe 2 cannot be connected with the exhaust channel 311, that is, the steam in the pot cannot be discharged to the outside through the exhaust channel 311. At this time, the pressure cooker is in an upward pressure state, and the pressure in the pot can rise rapidly, so as to heat the food. When the pressure in the pressure cooker exceeds a preset range, the valve body 31 can move to the second working position away from the cover body 1 under the action of pressure, that is, the valve core 312 moves to the side away from the exhaust pipe 2, thereby opening the exhaust pipe 2 and connecting the exhaust pipe 2 with the exhaust channel 311. At this time, the pressure cooker is in a pressure relief state, and the steam in the pot enters the exhaust channel 311 through the exhaust pipe 2 and is then discharged to the outside, so that the pressure in the pressure cooker is kept within a safe range. As the steam is discharged, the pressure of the pressure cooker decreases. At this time, the valve body 31 can move to the side close to the cover body 1 under the action of its own gravity, so that the valve core 312 re-blocks the exhaust pipe 2, that is, the valve body 31 returns to the above-mentioned first working position, which is convenient for the next cooking work of the pressure cooker.

[0060] Among them, along the axial direction Z of the container cover 10, the valve cover 32 is located above the valve body 31 and is fixedly connected to the valve body 31, that is, the valve cover 32 moves with the valve body 31. There is a buffer space 33 between the valve cover 32 and the valve body 31. When the valve body 31 is located at the second working position mentioned above, the steam in the pot enters the exhaust channel 311 through the exhaust pipe 2, and then enters the buffer space 33 from the exhaust channel 311, and finally is discharged to the outside through the first exhaust hole 321. It can be seen that the valve assembly 3 in the embodiment of the present application adopts an upward exhaust method to exhaust.

[0061] At present, the pressure limiting valve on the lid of the pressure cooker is usually vented downward, so that the pressure limiting valve is easily affected by the airflow during the venting process and vibrates violently, thereby generating noise, affecting the user's experience. At the same time, the safety of the pressure limiting valve is low, and the user is easily scalded by the steam ejected from the pressure limiting valve. Compared with the prior art, the exhaust channel 311, the buffer space 33 and the first exhaust hole 321 in the embodiment of the present application are arranged in sequence from bottom to top along the axial direction Z of the container cover 10, and the steam discharged from the exhaust pipe 2 is discharged to the outside through the exhaust channel 311, the buffer space 33 and the first exhaust hole 321 in sequence, that is, the valve assembly 3 provided in the embodiment of the present application realizes the function of upward exhaust. During the exhaust process, the steam is ejected upward, and the exhaust path provided by the valve assembly 3 for the steam can be adapted to the direction of the steam ejection, so as to facilitate the realization of a smooth and smooth exhaust process, reduce the possibility of the valve assembly 3 vibrating violently during the exhaust process due to the influence of the airflow, thereby improving the stability and reliability of the operation of the valve assembly 3, and at the same time, reduce the possibility of the valve assembly 3 making noise due to the vibration, thereby improving the user's experience. At the same time, the embodiment of the present application is provided with a buffer space 33 between the valve cover 32 and the valve body 31, so that the steam discharged from the exhaust channel 311 can be buffered in the buffer space 33, and then discharged to the outside through the first exhaust hole 321, which is beneficial to slow down the flow rate of the steam, thereby reducing the possibility of strong steam and liquid splashing to the outside through the first exhaust hole 321 and causing safety hazards to users, which is beneficial to improving the safety of the use of the valve assembly 3, that is, improving the safety of the container cover 10 and the entire pressure cooker.

[0062] like Figure 2 and Figure 3 As shown, in a possible implementation, the valve cover 32 includes an arc portion 322 , which protrudes toward a side away from the valve body 31 . The buffer space 33 is located between the arc portion 322 and the valve body 31 , and the first exhaust hole 321 is opened in the arc portion 322 .

[0063] The first exhaust hole 321 can be arranged at the center of the arc portion 322, that is, at the top of the arc portion 322. By arranging the arc portion 322 on the valve cover 32, the space provided for the buffer space 33 is increased, so as to buffer the steam discharged from the exhaust channel 311. The arc portion 322 can gather the steam entering the buffer space 33, so that the steam can be discharged to the outside through the first exhaust hole 321 on the valve cover 32, which is conducive to achieving stable and smooth exhaust work of the valve assembly 3, and further conducive to improving the safety of the container cover 10.

[0064] like Figure 2 and Figure 3 As shown, in a possible embodiment, the valve body 31 also includes a valve seat 313 and a valve cover 314 fixedly connected to the outside of the valve seat 313; the valve core 312 is fixedly connected to the valve cover 314, the valve seat 313 has a accommodating cavity 311a, and the valve core 312 extends into the accommodating cavity 311a; one end of the exhaust pipe 2 is in the accommodating cavity 311a and is movably connected to the valve seat 313; the valve cover 314 has a second exhaust hole 311b, one end of the second exhaust hole 311b is connected to the accommodating cavity 311a to form an exhaust channel 311, and the other end of the second exhaust hole 311b is connected to the buffer space 33.

[0065] The valve cover 314 has a containing space, and the valve core 312 and the valve seat 313 can be contained in the containing space. The valve core 312 can be fixedly connected to the top wall of the valve cover 314; the valve seat 313 can be fixedly connected to the side wall of the valve cover 314, so that the valve core 312, the valve cover 314 and the valve seat 313 can move relative to the exhaust pipe 2 along the axial direction Z of the container cover 10. The valve cover 314, the valve core 312 and the valve seat 313 can be made of metal materials, or plastic. The exhaust channel 311 includes a second exhaust hole 311b and an accommodating chamber 311a that are interconnected, and the accommodating chamber 311a and the second exhaust hole 311b can extend along the axial direction Z of the container cover 10. When the valve body 31 is in the second working position, the exhaust pipe 2 is opened, and the steam enters the accommodating chamber 311a through the exhaust pipe 2, and then enters the buffer space 33 through the second exhaust hole 311b, and finally is discharged to the outside through the first exhaust hole 321.

[0066] The embodiment of the present application is advantageous in improving the stability and reliability of the valve core 312 by setting the valve cover 314, so that the valve core 312 can block or open the exhaust pipe 2, thereby facilitating the normal use of the valve assembly 3. At the same time, the valve cover 314 is provided with a second exhaust hole 311b, and the steam discharged from the accommodating chamber 311a enters the buffer space 33 through the second exhaust hole 311b. The second exhaust hole 311b is advantageous in extending the length of the exhaust channel 311, thereby playing a certain buffering role for the steam, and is advantageous in reducing the possibility of the steam rapidly splashing to the outside and bringing safety hazards to the user, thereby improving the safety of the use of the valve assembly 3. On the other hand, the valve seat 313 provides a space for accommodating and exhausting the exhaust pipe 2. By fixing the valve seat 313 and the valve cover 314 together, it is advantageous in improving the reliability of the entire valve assembly 3, so that the valve assembly 3 can work normally and stably.

[0067] like Figure 2 and Figure 3 As shown, in a possible implementation manner, the first exhaust hole 321 and the second exhaust hole 311 b are staggered.

[0068] The shape of the first exhaust hole 321 may also be circular, rectangular or other shapes. The shape of the second exhaust hole 311b may also be the same as or different from the shape of the first exhaust hole 321. The axis of the first exhaust hole 321 does not coincide with the axis of the second exhaust hole 311b, that is, the two are arranged in a staggered manner. This design is conducive to slowing down the flow rate of steam, that is, it has a buffering effect on the steam, reducing the possibility of strong steam splashing out from the first exhaust hole 321, thereby improving the safety of the valve assembly 3.

[0069] In some embodiments, both the first exhaust hole 321 and the second exhaust hole 311b may extend along the axial direction Z of the container cover 10. In other embodiments, one or both of the first exhaust hole 321 or the second exhaust hole 311b may extend along a direction inclined to the axial direction Z of the container cover 10 to further slow down the flow rate of the steam and reduce the possibility of violent splashing of the steam to the outside.

[0070] like Figure 3 In a possible implementation, the valve cover 32 has a plurality of first exhaust holes 321, and the plurality of first exhaust holes 321 are arranged along the circumference of the valve cover 32. The valve housing 314 has a plurality of second exhaust holes 311b, and the plurality of second exhaust holes 311b are arranged along the circumference of the valve housing 314.

[0071] Specifically, the valve cover 32 may have four first exhaust holes 321, and the four first exhaust holes 321 are arranged at intervals along the circumference of the valve cover 32. The valve cover 314 may have four second exhaust holes 311b, and the four second exhaust holes 311b are arranged at intervals along the circumference of the valve cover 314. By providing a plurality of first exhaust holes 321 and a plurality of second exhaust holes 311b, it is beneficial to improve the exhaust efficiency of the valve assembly 3, so that the steam in the pot can be quickly discharged, so that the pressure cooker in the pot can be restored to a safe range as soon as possible, so as to improve the safety of the valve assembly 3 and the entire pressure cooker, and reduce the possibility of explosion of the pressure cooker.

[0072] The first exhaust hole 321 and the second exhaust hole 311b may be staggered, for example, the second exhaust hole 311b may be disposed outside the first exhaust hole 321. More specifically, the first exhaust hole 321 may be disposed in the central area of ​​the valve cover 314, and the second exhaust hole 311b may be disposed in the edge area of ​​the valve cover 314.

[0073] like Figure 3 and Figure 4 As shown, in a possible implementation, the valve cover 314 is provided with at least one engaging groove 314a. The valve cover 32 further includes at least one engaging portion 323, and the engaging portion 323 is engaged with the engaging groove 314a.

[0074] The engaging groove 314a is provided on the upper surface of the valve cover 314, and the engaging groove 314a can extend along the axial direction Z of the container cover 10. The engaging portion 323 is located on one side of the arc portion 322, and extends toward the valve core 312 away from the arc portion 322. Specifically, the engaging portion 323 includes a plurality of engaging ribs 323a, and the plurality of engaging ribs 323a can form a "T"-shaped structure, or an "X"-shaped structure, so as to improve the stability of the engagement between the engaging portion 323 and the engaging groove 314a. By setting the engagement between the engaging groove 314a and the engaging portion 323, it is helpful to improve the stability of the connection between the valve cover 314 and the valve cover 32, and reduce the possibility of the valve cover 32 falling off from the valve cover 314 under the action of steam, so as to improve the reliability of the valve assembly 3 as a whole.

[0075] like Figure 3 As shown, in some embodiments, the valve cover 314 is provided with a plurality of snap-fit ​​grooves 314a, and the valve cover 32 has a plurality of snap-fit ​​portions 323, which cooperate with the corresponding snap-fit ​​grooves 314a. By providing a plurality of snap-fit ​​grooves 314a and a plurality of snap-fit ​​portions 323, the stability of the connection between the valve cover 314 and the valve cover 32 is further improved.

[0076] In another possible implementation, the valve cover 32 may be threadedly connected to the valve housing 314 , or connected to the valve housing 314 via fasteners such as screws.

[0077] like Figure 2 As shown, in a possible implementation, the valve seat 313 has an abutment portion 313 a extending along its own radial direction X toward a side away from the accommodating cavity 311 a , and along the axial direction Z of the exhaust pipe 2 , the valve cover 314 abuts against the abutment portion 313 a .

[0078] The valve seat 313 can be threadedly connected to the valve cover 314. The abutment portion 313a can be arranged around the circumference of the valve seat 313, that is, the abutment portion 313a can also be an annular boss. The abutment portion 313a acts as a limiter on the valve cover 314 by abutting against the valve cover 314, thereby facilitating the stability and reliability of the connection between the valve cover 314 and the valve seat 313 and reducing the possibility of the valve cover 314 and the valve seat 313 being separated from each other.

[0079] like Figure 2 As shown, in a possible implementation manner, the valve seat 313 has a mounting groove 313 b communicating with the accommodating cavity 311 a , a connecting piece 4 is disposed in the mounting groove 313 b , and the exhaust pipe 2 is connected to the valve seat 313 via the connecting piece 4 .

[0080] The connector 4 may be a retaining spring, which is sleeved on the outside of the exhaust pipe 2 to achieve a movable connection between the valve seat 313 and the exhaust pipe 2, that is, the valve body 31 can move along the axial direction Z of the exhaust pipe 2 to block or open the exhaust pipe 2. Of course, the connector 4 may also be a part of other forms, as long as it meets the use requirements of the valve body 31 and the exhaust pipe 2.

[0081] Such a design is conducive to improving the stability and reliability of the connection between the valve body 31 and the exhaust pipe 2, and reducing the possibility of the valve body 31 falling off the exhaust pipe 2, thereby facilitating the pressure cooker to achieve normal pressure-up and pressure-release operations.

[0082] like Figure 5 As shown, in a possible implementation manner, the valve core 312 and the valve cover 314 are integrally formed, wherein the valve core 312 includes a valve head 312 a , and the diameter of the valve head 312 a gradually decreases toward a side close to the exhaust pipe 2 .

[0083] Specifically, the valve core 312 and the valve cover 314 can be integrally injection molded to improve the stability of the connection between the valve core 312 and the valve cover 314, thereby facilitating the improvement of the overall reliability of the valve assembly 3. The valve head 312a of the valve core 312 can be tapered to facilitate cooperation with the opening of the exhaust pipe 2, thereby improving the sealing effect of the valve core 312 on the exhaust pipe 2, and reducing the possibility of steam leaking outward from between the valve head 312a and the exhaust pipe 2 during the plugging process, thereby ensuring the normal use of the valve assembly 3.

[0084] In some other possible implementations, the valve core 312 may also be snap-fitted to the valve cover 314 or fixedly connected in other ways.

[0085] The embodiment of the present application also provides a cooking container, comprising a container body, a container cover 10 and a valve assembly 3, wherein the container cover 10 covers the container body, the valve assembly 3 is installed on the container cover 10, and the valve assembly 3 is any one of the valve assemblies 3 described above.

[0086] The cooking container can be a pressure cooker, and the container body is the pot body of the pressure cooker. When the pressure cooker is ready to cook, the valve body 31 is in the first working position so that the pressure cooker can be pressurized. After the pressure in the pressure cooker exceeds a preset range, the valve body 31 can move to the second working position under the action of pressure to make the pressure cooker depressurize to reduce the possibility of explosion of the pressure cooker. Since the valve assembly 3 can achieve the above-mentioned technical effects, the cooking container having the valve assembly 3 can also achieve the above-mentioned technical effects, which will not be repeated here.
