Description

Technical Field

[0001] This utility model relates to the field of cooking utensils technology, and in particular to a novel micro-pressure valve and micro-pressure cooker. Background Technology

[0002] Pressure cookers can be divided into pressure cookers, pressure fryers, etc. The pressure when a pressure cooker is working is generally less than 1.2 atmospheres. Under this pressure, it is easier to cook food than with a regular pot, and the lid can be opened at any time while it is working.

[0003] However, in order to ensure that the lid can be opened at any time and that a certain pressure is maintained inside the pot, existing pressure cookers either have a pressure device between the lid and the pot body, but this makes the lid difficult to open and can easily turn into a pressure cooker, making it difficult to guarantee safety; or they use a simple connecting device to connect the pot body and the lid, but in this case, it is difficult to increase the pressure inside the pot and achieve the performance of a pressure cooker. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a new type of micro-pressure valve and micro-pressure cooker.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A novel micro-pressure valve includes:

[0007] The valve body has a pressure relief chamber inside, and the upper end of the valve body has multiple pressure relief channels that communicate with the pressure relief chamber. The lower end of the valve body also has a connecting hole that communicates with the pressure relief chamber.

[0008] A pressure regulating component is movably disposed within the pressure relief chamber, wherein the pressure regulating component falls freely under the action of gravity and presses against the upper end face of the connecting hole to cut off the communication between the connecting hole and the pressure relief chamber;

[0009] A valve seat is connected to the lower end of the valve body and is used to connect with the pot lid assembly to install the valve body onto the pot lid assembly;

[0010] When the pressure in the pot exceeds a set threshold, the excess steam inside the pot pushes the pressure regulating component upward to connect the connecting hole and the pressure relief chamber, so that the excess steam passes through the connecting hole, the pressure relief chamber and the pressure relief channel in sequence and is discharged outside the pot.

[0011] As described above, in a novel micro-pressure valve, the pressure regulating element is a spherical body, and the connecting hole is a circular through hole that mates with the pressure regulating element.

[0012] In the novel micro-pressure valve described above, the diameter of the pressure regulating element is larger than the diameter of the connecting hole.

[0013] As described above, in a novel micro-pressure valve, a connecting ring extends outward from the lower circumference of the valve body, and an assembly structure is provided between the connecting ring and the valve seat.

[0014] As described above, a novel micro-pressure valve has an assembly structure comprising a retaining ring groove formed on the inner sidewall of the connecting ring portion, and a retaining ring disposed on the valve seat and capable of being embedded in the retaining ring groove.

[0015] As described above, in a novel micro-pressure valve, several sealing ribs are also arranged on the outer wall of the connecting ring.

[0016] In the novel micro-pressure valve described above, the connecting ring is integrally formed with the valve body, and the retaining ring is integrally formed with the valve seat.

[0017] This application also discloses a micro pressure cooker, including a pot body and a pot lid assembly covering the upper end of the pot body. The pot lid assembly has a pressure relief groove seat, and the bottom of the pressure relief groove seat has a pressure relief grid. A novel micro pressure valve as described above can also be detachably connected inside the pressure relief groove seat.

[0018] As described above, a detachable structure is also provided between the pressure relief groove seat and the valve seat in a micro-pressure cooker.

[0019] As described above, the disassembly and assembly structure includes a screw-locking groove at the bottom of the pressure relief seat and a screw-locking protrusion protruding from the lower end of the valve seat and capable of being embedded in the screw-locking groove for engagement.

[0020] The beneficial effects of this utility model are as follows: This application has a simple structure. With the setting of valve body and pressure regulating component, under normal use, the pressure regulating component falls freely under the action of gravity and presses against the upper end face of the connecting hole to cut off the connection between the connecting hole and the pressure relief chamber, thus automatically maintaining the pressure state inside the pot. When the pressure inside the pot exceeds the set threshold, the excess steam inside the pot pushes the pressure regulating component upward to connect the connecting hole and the pressure relief chamber, so that the excess steam passes through the connecting hole, the pressure relief chamber and the pressure relief channel in sequence and is discharged outside the pot to relieve pressure. Until the pressure inside the pot returns to the normal state, the pressure regulating component falls freely under the action of gravity to return to its original state and continues to maintain the normal pressure state inside the pot. It is practical and convenient, and avoids the occurrence of excessive or insufficient pressure inside the pot for a long time. Attached Figure Description

[0027] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0028] Please see Figures 1 to 5 As shown, this application embodiment provides a micro pressure cooker, including a pot body 100 and a pot lid assembly 101 covering the upper end of the pot body 100. The pot lid assembly 101 is provided with a pressure relief groove seat 6, and a pressure relief grille 60 is provided at the bottom of the pressure relief groove seat 6. A novel micro pressure valve can also be detachably connected inside the pressure relief groove seat 6.

[0029] The novel micro-pressure valve includes:

[0030] The valve body 1 has a pressure relief chamber 10 inside. The upper end of the valve body 1 has a plurality of pressure relief channels 11 that communicate with the pressure relief chamber 10. The lower end of the valve body 1 also has a connecting hole 12 that communicates with the pressure relief chamber 10.

[0031] Pressure regulating component 2 is movably disposed within the pressure relief chamber 10. The pressure regulating component 2 falls freely under the action of gravity and presses against the upper end face of the connecting hole 12 to cut off the communication between the connecting hole 12 and the pressure relief chamber 10.

[0032] Valve seat 3 is connected to the lower end of the valve body 1 and is used to connect with the pot lid assembly 101 to install the valve body 1 on the pot lid assembly 101;

[0033] When the pressure in the pot body 100 exceeds a set threshold, the excess steam in the pot body 100 pushes the pressure regulating member 2 upward to connect the connecting hole 12 and the pressure relief chamber 10, so that the excess steam passes through the connecting hole 12, the pressure relief chamber 10 and the pressure relief channel 11 in sequence and is discharged outside the pot body 100.

[0034] With the valve body 1 and pressure regulating component 2 in normal use, the pressure regulating component 2 falls freely under gravity and presses against the upper end face of the connecting hole 12 to cut off the connection between the connecting hole 12 and the pressure relief chamber 10, thus automatically maintaining the pressure state inside the pot. When the pressure in the pot 100 exceeds the set threshold, the excess steam inside the pot 100 pushes the pressure regulating component 2 upward to connect the connecting hole 12 and the pressure relief chamber 10, allowing the excess steam to pass through the connecting hole 12, the pressure relief chamber 10, and the pressure relief channel 11 in sequence and be discharged outside the pot 100 to relieve pressure. When the pressure inside the pot returns to normal, the pressure regulating component 2 falls freely under gravity to return to its original state, continuing to maintain the normal pressure state inside the pot. This is practical and convenient, avoiding situations where the pressure inside the pot is too high or too low for a long time.

[0035] Furthermore, the pressure regulating component 2 is a spherical body, and the connecting hole 12 is a circular through hole that mates with the pressure regulating component 2.

[0036] Specifically, the diameter of the pressure regulating element 2 is greater than the diameter of the connecting hole 12.

[0037] By using the combination of a spherical body and a circular through hole, the pressure regulating component 2 can fully cover the connecting hole 12 when it falls freely under gravity and presses against the upper surface of the connecting hole 12 under normal conditions, thus ensuring the normal use of the micro pressure cooker.

[0038] In this embodiment, the pressure regulating component 2 is a steel ball, and the specific size and mass of the steel ball can be selected according to the specific needs of maintaining a stable pressure value, which is practical and convenient.

[0039] Furthermore, a connecting ring portion 13 extends outward from the lower periphery of the valve body 1, and an assembly structure 4 is provided between the connecting ring portion 13 and the valve seat 3.

[0040] Specifically, the assembly structure 4 includes a retaining ring groove 41 formed on the inner side wall of the connecting ring portion 13, and a retaining ring 42 provided on the valve seat 3 and capable of being embedded in the retaining ring groove 41.

[0041] The micro-pressure valve can be disassembled and assembled by the engagement of the locking ring groove 41 and the ring 42, which facilitates maintenance, cleaning, and individual replacement of each component, making it practical and convenient.

[0042] Furthermore, several sealing ribs 5 are arranged on the outer wall of the connecting ring portion 13. This ensures the overall sealing performance of the micro-pressure valve after it is installed on the pressure relief groove seat 6, making it practical and convenient.

[0043] Specifically, the connecting ring 13 is integrally formed with the valve body 1, and the retaining ring 42 is integrally formed with the valve seat 3. This facilitates processing and production, and is practical and convenient.

[0044] Furthermore, a disassembly structure 7 is provided between the pressure relief groove seat 6 and the valve seat 3.

[0045] Specifically, the disassembly and assembly structure 7 includes a screw-locking groove 71 opened at the bottom of the pressure relief groove seat 6, and a screw-locking protrusion 72 protruding from the lower end of the valve seat 3 and capable of being embedded in the screw-locking groove 71 for engagement.

[0046] During installation, align the screw-on locking protrusion 72 with the screw-on locking groove 71, then move it downwards to insert the micro-pressure valve into the pressure relief groove 6 until the screw-on locking protrusion 72 passes through the screw-on locking groove 71. Then screw the micro-pressure valve and the screw-on locking protrusion 72 so that both ends of the screw-on locking protrusion 72 press against the bottom of the pressure relief groove 6 to complete the installation. Disassembly is the reverse process, which realizes the separate setting of the micro-pressure valve and the pot lid assembly 101, allowing the micro-pressure valve to be maintained and replaced separately, which is practical and convenient.

[0047] In summary, this embodiment of the application, through the setting of valve body 1 and pressure regulating component 2, allows the pressure regulating component 2 to fall freely under gravity and press against the upper end face of the connecting hole 12 to cut off the connection between the connecting hole 12 and the pressure relief chamber 10, thus automatically maintaining the pressure state inside the pot. When the gas pressure in the pot body 100 exceeds the set threshold, the excess steam inside the pot body 100 pushes the pressure regulating component 2 upward to connect the connecting hole 12 and the pressure relief chamber 10, allowing the excess steam to pass through the connecting hole 12, the pressure relief chamber 10, and the pressure relief channel 11 in sequence and be discharged outside the pot body 100 to relieve pressure. When the pressure inside the pot returns to normal, the pressure regulating component 2 falls freely under gravity to return to its original state, continuing to maintain the normal pressure state inside the pot. This is practical and convenient, avoiding situations where the pressure inside the pot is too high or too low for a long time.

[0048] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structure made using the contents of this utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of this utility model.
