Description

Technical Field

[0001] This utility model relates to the field of micro pressure cooker technology, and in particular to an automatic pressure stabilizing mechanism for a micro pressure cooker pressure valve. 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 an automatic pressure stabilizing mechanism for a micro pressure cooker pressure valve.

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

[0006] An automatic pressure stabilizing mechanism for a micro pressure cooker includes a valve seat, a valve cover, a movable piston, and an elastic pressing member. The valve seat is detachably connected to the pot cover, the valve cover is installed on the valve seat, the movable piston is movably disposed inside the valve cover, and the elastic pressing member is movably disposed between the valve cover and the movable piston and can press the movable piston against the valve seat. Several pressure relief holes are also provided on the peripheral wall of the valve cover above the movable piston.

[0007] As described above, in the automatic pressure stabilizing mechanism of the pressure valve of a micro pressure cooker, the movable piston is further provided with a pressure relief groove that can communicate with the corresponding pressure relief through hole.

[0008] As described above, in the automatic pressure stabilizing mechanism of a micro pressure cooker pressure valve, a cylinder protrudes from the upper end of the moving piston, one end of the elastic pressing member is sleeved on the cylinder and presses against the upper end of the moving piston, and the other end of the elastic pressing member presses against the inner top wall of the valve cover.

[0009] As described above, in the automatic pressure stabilizing mechanism of the pressure valve of a micro pressure cooker, a pressure relief chamber is also provided inside the valve cover, the movable piston and the elastic top pressure member are movably disposed in the pressure relief chamber, and the pressure relief through hole is connected to the pressure relief chamber.

[0010] As described above, the automatic pressure stabilizing mechanism of the pressure valve of a micro pressure cooker also includes a disassembly structure between the valve seat and the valve cover.

[0011] As described above, the automatic pressure stabilizing mechanism of a micro pressure cooker pressure valve includes a locking ring groove formed on the inner wall of the pressure relief chamber, and a locking protrusion provided on the valve seat and capable of being embedded in the locking ring groove.

[0012] As described above, in the automatic pressure stabilizing mechanism of the pressure valve of a micro pressure cooker, the peripheral wall of the moving piston is fitted to the inner wall of the pressure relief chamber.

[0013] As described above, in the automatic pressure stabilizing mechanism of a micro pressure cooker pressure valve, the valve seat is further provided with a guide post, and the movable piston is sleeved on the guide post.

[0014] In the above-described automatic pressure stabilizing mechanism for a micro pressure cooker pressure valve, the elastic pressure-pressing component is a spring.

[0015] As described above, the automatic pressure stabilizing mechanism of the pressure valve of a micro pressure cooker also has an installation cavity on the pot lid, and an installation structure is provided between the bottom of the installation cavity and the valve seat.

[0016] The beneficial effects of this utility model are as follows: This application has a simple structure. Through the cooperation of the moving piston and the elastic pressing component, when the pressure inside the pot is too high, the excess steam presses the moving piston upward until it is higher than the pressure relief hole, so that the pressure relief hole is connected to the space inside the pot. This allows the excess steam inside the pot to escape from the pressure relief hole and relieve pressure. When the pressure inside the pot returns to normal, the elastic pressing component presses the moving piston onto the valve seat, re-cutting off the connection between the pressure relief hole and the inside of the pot, automatically maintaining the 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

[0023] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1 to 5 As shown in the figure, this application embodiment provides an automatic pressure stabilizing mechanism for a micro pressure cooker pressure valve, including a valve seat 1, a valve cover 2, a movable piston 3, and an elastic pressing member 4. The valve seat 1 is detachably connected to the pot cover 100, the valve cover 2 is installed on the valve seat 1, the movable piston 3 is movably disposed inside the valve cover 2, and the elastic pressing member 4 is movably disposed between the valve cover 2 and the movable piston 3 and can press the movable piston against the valve seat 1. Several pressure relief holes 5 are also provided on the peripheral side wall of the valve cover 2 above the movable piston 3.

[0025] By cooperating with the movable piston 3 and the elastic pressure member 4, when the pressure inside the pot is too high, the excess steam pushes the movable piston 3 upward until it is higher than the pressure relief hole 5, so that the pressure relief hole 5 is connected to the space inside the pot. This allows the excess steam inside the pot to escape from the pressure relief hole 5 and relieve pressure. When the pressure inside the pot returns to normal, the elastic pressure member 4 pushes the movable piston 3 onto the valve seat 1, and cuts off the connection between the pressure relief hole 5 and the inside of the pot again, automatically maintaining the pressure state inside the pot. This is practical and convenient, and avoids the occurrence of excessive or insufficient pressure inside the pot for a long time.

[0026] Furthermore, the movable piston 3 is also provided with a pressure relief groove 30 that can communicate with the corresponding pressure relief through hole 5.

[0027] By designing the pressure relief groove 30, when the pressure inside the pot is too high, the excess steam pushes the moving piston 3 upward until its upper end face is higher than the pressure relief hole 5, so that the pressure relief hole 5 is connected to the pressure relief groove 30 and then to the space inside the pot. This allows the excess steam inside the pot to escape from the pressure relief groove 30 and the pressure relief hole 5, thus relieving pressure. When the pressure inside the pot returns to normal, the elastic pressing element 4 pushes the moving piston 3 onto the valve seat 1, re-cutting off the connection between the pressure relief hole 5 and the inside of the pot, automatically maintaining the pressure state inside the pot. This is practical and convenient, and avoids situations where the pressure inside the pot is too high or too low for a long time.

[0028] Furthermore, a cylinder 31 protrudes from the upper end of the movable piston 3. One end of the elastic pressing member 4 is sleeved on the cylinder 31 and presses against the upper end of the movable piston 3, while the other end of the elastic pressing member 4 presses against the inner top wall of the valve cover 2. Through the connection between the elastic pressing member 4 and the cylinder 31, the elastic pressing member 4 can always press against the upper end of the movable piston 3, ensuring the smooth and normal operation of the pressure stabilizing mechanism.

[0029] Specifically, the valve cover 2 is further provided with a pressure relief chamber 20, the movable piston 3 and the elastic pressing member 4 are movably disposed in the pressure relief chamber 20, and the pressure relief through hole 5 is connected to the pressure relief chamber 20.

[0030] Furthermore, a disassembly structure 6 is provided between the valve seat 1 and the valve cover 2.

[0031] Specifically, the disassembly / assembly structure 6 includes a locking ring groove 61 formed on the inner wall of the pressure relief chamber 20, and a locking protrusion 62 disposed on the valve seat 1 and capable of being embedded in the locking ring groove 61. Through the cooperative arrangement of the locking ring groove 61 and the locking protrusion 62, the pressure stabilizing mechanism can be disassembled and assembled, facilitating maintenance, cleaning, and individual replacement of each component, making it practical and convenient.

[0032] Furthermore, the circumferential sidewalls of the movable piston 3 are fitted into the inner wall of the pressure relief chamber 20. This reduces the possibility of steam escaping from the boiler under normal circumstances.

[0033] Furthermore, the valve seat 1 is also provided with a guide post 10, and the movable piston 3 is sleeved on the guide post 10. This ensures that the moving direction of the movable piston 3 remains perpendicular to the valve seat 1.

[0034] Specifically, the elastic pressing member 4 is a spring.

[0035] In this embodiment, a spring with a suitable elastic coefficient value can be selected and set according to the pressure value required by the micro pressure cooker.

[0036] Furthermore, the pot lid 100 is provided with an installation cavity 101, and an installation structure 7 is provided between the bottom of the installation cavity 101 and the valve seat 1.

[0037] In this embodiment, the mounting structure 7 is a common existing technology in the field (such as a screw-on locking structure, etc.), and will not be described in detail here.

[0038] In summary, this embodiment of the application, through the coordinated arrangement of the movable piston 3 and the elastic pressing member 4, allows the excessive steam to push the movable piston 3 upwards when the pressure inside the pot is too high, until it is higher than the pressure relief hole 5. This connects the pressure relief hole 5 with the space inside the pot, allowing the excess steam inside the pot to escape through the pressure relief hole 5 and relieve pressure. When the pressure inside the pot returns to normal, the elastic pressing member 4 presses the movable piston 3 onto the valve seat 1, reconnecting the pressure relief hole 5 with the inside of the pot, automatically maintaining the pressure state inside the pot. This is practical and convenient, preventing situations where the pressure inside the pot is too high or too low for an extended period of time.

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.
