Description

Technical Field

[0001] This utility model relates to the field of cooking utensils technology, and in particular to a 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 existing micro pressure cookers, the valve body is usually integrated directly onto the lid, making it impossible to maintain or replace the valve body separately. If the valve body is damaged, the entire lid needs to be taken for repair, which is very troublesome. Summary of the Invention

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

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

[0006] A pressure cooker, comprising:

[0007] Pot body;

[0008] A lid is placed over the upper part of the pot body;

[0009] The mounting slot is provided on the pot lid, and a screw-on groove is provided at the bottom of the slot, as well as a pressure relief grille surrounding the screw-on groove.

[0010] The pressure regulating valve assembly is movably disposed in the mounting slot, and its bottom is also provided with a screw-locking protrusion that can be embedded in the screw-locking slot for engagement. When the gas pressure of the pot exceeds the set threshold, excess steam in the pot passes through the pressure relief grille and is discharged through the pressure regulating valve assembly.

[0011] As described above, a micro pressure cooker is further provided with a locking mechanism on the pot body that can press the pot lid tightly against the upper end of the pot body.

[0012] As described above, in a micro pressure cooker, the locking mechanism includes a locking seat disposed on the upper periphery of the cooker body, and a locking block slidably disposed on the locking seat.

[0013] As described above, in a micro pressure cooker, the pressure regulating valve assembly includes a valve seat, a valve cover, a movable piston, and an elastic pressing member. The valve seat is connected to a mounting groove, the valve cover is mounted on the valve seat, the movable piston is movably disposed within 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. A plurality of pressure relief holes are also provided on the peripheral sidewall of the valve cover above the movable piston.

[0014] In the micro-pressure cooker described above, the peripheral wall of the movable piston is fitted to the inner wall of the valve cover.

[0015] In the micro pressure cooker described above, the movable piston is further provided with a pressure relief groove that can communicate with the corresponding pressure relief through hole.

[0016] As described above, in a micro pressure cooker, a cylinder protrudes from the upper end of the movable piston, one end of the elastic pressing member is sleeved on the cylinder and presses against the upper end of the movable piston, and the other end of the elastic pressing member presses against the inner top wall of the valve cover.

[0017] As described above, a detachable structure is also provided between the valve seat and the valve cover in a micro pressure cooker.

[0018] As described above, the disassembly and assembly structure includes a locking ring groove formed on the inner wall of the valve cover, and a locking protrusion provided on the valve seat and capable of being embedded in the locking ring groove.

[0019] As described above, in a micro pressure cooker, the valve seat is further provided with a guide post, and the lower end of the moving piston is provided with a guide groove that can be fitted onto the guide post. The screw clip protrudes from the lower end of the guide post and extends out of the lower end of the valve seat.

[0020] The beneficial effects of this utility model are as follows: This application has a simple structure. By opening an installation slot on the pot lid and using the cooperation of a screw-on slot and a screw-on protrusion, during installation, the screw-on protrusion is aligned with the screw-on slot, and then moved downward to insert the pressure regulating valve assembly into the installation slot until the screw-on protrusion passes through the screw-on slot. Then, the pressure regulating valve assembly and the screw-on protrusion are screwed so that the two ends of the screw-on protrusion press against the bottom of the installation slot to complete the installation. Disassembly is the reverse process. This achieves the separate setting of the pressure regulating valve assembly and the pot lid, allowing for independent maintenance and replacement of the pressure regulating valve assembly, which is practical and convenient.

[0030] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0031] Please see Figures 1 to 8 As shown in the figure, this application provides a micro pressure cooker, characterized in that it includes:

[0032] Pot body 1;

[0033] Pot lid 2 is placed on the upper end of the pot body 1;

[0034] The mounting slot 3 is provided on the pot lid 2, and a screw-on slot 30 is provided at the bottom of the slot 30, and a pressure relief grille 31 is provided around the screw-on slot 30.

[0035] The pressure regulating valve assembly 4 is movably disposed in the mounting slot 3, and its bottom is also provided with a screw-locking protrusion 40 that can be embedded in the screw-locking slot 30 for engagement. When the gas pressure of the pot body 1 exceeds the set threshold, the excess steam in the pot body 1 passes through the pressure relief grille 31 and is discharged through the pressure regulating valve assembly 4.

[0036] By creating an installation slot 3 on the pot lid, and cooperating with a screw-on groove 30 and a screw-on protrusion 40, during installation, align the screw-on protrusion 40 with the screw-on groove 30, then move it downwards to insert the pressure regulating valve assembly 4 into the installation slot 3 until the screw-on protrusion 40 passes through the screw-on groove 30. Then screw the pressure regulating valve assembly 4 and the screw-on protrusion 40 so that both ends of the screw-on protrusion 40 press against the bottom of the installation slot 3 to complete the installation. Disassembly is the reverse process, achieving a separate installation of the pressure regulating valve assembly 4 and the pot lid 2, allowing for independent maintenance and replacement of the pressure regulating valve assembly 4, which is practical and convenient.

[0037] Furthermore, the pot body 1 is also provided with a locking mechanism 5 that can press the pot lid 2 tightly against the upper end of the pot body 1.

[0038] Specifically, the locking mechanism 5 includes a locking seat 51 disposed on the upper periphery of the pot body 1, and a locking block 52 slidably disposed on the locking seat 51.

[0039] When in use, after placing the lid 2 on the pot body 1, move the locking block 52 so that one end of it presses firmly onto the lid 2 to complete the fixation. It is practical and convenient.

[0040] In this embodiment, the working principle of the locking mechanism 5 is a common existing technology in the field, and will not be described in detail here.

[0041] Furthermore, the pressure regulating valve assembly 4 includes a valve seat 41, a valve cover 42, a movable piston 43, and an elastic pressing member 44. The valve seat 41 is connected to the mounting groove 3, the valve cover 42 is mounted on the valve seat 41, the movable piston 43 is movably disposed within the valve cover 42, and the elastic pressing member 44 is movably disposed between the valve cover 42 and the movable piston 43 and can press the movable piston against the valve seat 41. Several pressure relief through holes 45 are also provided on the peripheral side wall of the valve cover 42 above the movable piston 43.

[0042] By cooperating with the movable piston 43 and the elastic pressing member 44, when the pressure inside the pot body 1 is too high, the excess steam presses the movable piston 43 upward until it is higher than the pressure relief hole 45, so that the pressure relief hole 45 is connected to the space inside the pot body 1. This allows the excess steam inside the pot body 1 to escape from the pressure relief hole 45 and relieve pressure. When the pressure inside the pot body 1 returns to normal, the elastic pressing member 44 presses the movable piston 43 onto the valve seat 41, re-cutting off the connection between the pressure relief hole 45 and the pot body, automatically maintaining the pressure state inside the pot body 1. This is practical and convenient, and avoids the occurrence of excessive or insufficient pressure inside the pot body 1 for a long time.

[0043] Furthermore, the peripheral wall of the movable piston 43 is fitted to the inner wall of the valve cover 42. This reduces the possibility of steam escaping from the pot body 1 under normal circumstances.

[0044] Furthermore, the movable piston 43 is also provided with a pressure relief groove 430 that can communicate with the corresponding pressure relief through hole 45.

[0045] By designing the pressure relief groove 430, when the pressure inside the pot body 1 is too high, the excess steam pushes the moving piston 43 upward until its upper end face is higher than the pressure relief through hole 45, so that the pressure relief through hole 45 is connected to the pressure relief groove 430 and then to the space inside the pot body 1. This allows the excess steam inside the pot body 1 to escape from the pressure relief groove 430 and the pressure relief through hole 45, thus relieving pressure. When the pressure inside the pot body 1 returns to normal, the elastic pressing member 44 presses the moving piston 43 onto the valve seat 41, re-cutting off the connection between the pressure relief through hole 45 and the pot body 1, automatically maintaining the pressure state inside the pot body 1. This is practical and convenient, and avoids situations where the pressure inside the pot is too high or too low for a long time.

[0046] Furthermore, a cylinder 431 protrudes from the upper end of the movable piston 43. One end of the elastic pressing member 44 is sleeved on the cylinder 431 and presses against the upper end of the movable piston 43, while the other end of the elastic pressing member 44 presses against the inner top wall of the valve cover 42. Through the connection between the elastic pressing member 44 and the cylinder 431, the elastic pressing member 44 can always press against the upper end of the movable piston 43, ensuring the smooth and normal operation of the pressure regulating valve assembly 4.

[0047] Furthermore, a disassembly structure 46 is provided between the valve seat 41 and the valve cover 42.

[0048] Specifically, the disassembly / assembly structure 46 includes a retaining ring groove 461 formed on the inner sidewall of the valve cover 42, and a retaining protrusion 462 disposed on the valve seat 41 and capable of being embedded in the retaining ring groove 461. Through the cooperative arrangement of the retaining ring groove 461 and the retaining protrusion 462, the pressure regulating valve assembly 4 can be disassembled and assembled, facilitating maintenance, cleaning, and individual replacement of each component, making it practical and convenient.

[0049] Furthermore, the valve seat 41 is also provided with a guide post 410, and the lower end of the moving piston 43 is provided with a guide groove 432 that can be fitted onto the guide post 410. The screw-locking protrusion 40 is provided at the lower end of the guide post 410 and protrudes from the lower end of the valve seat 41. This ensures that the moving direction of the moving piston 43 remains perpendicular to the valve seat 41.

[0050] In this embodiment, the elastic pressing element 44 is a spring. Furthermore, a spring with a suitable elastic coefficient can be selected and configured according to the pressure value required by the micro-pressure cooker.

[0051] In summary, this embodiment of the application, by providing an installation slot 3 on the pot lid and the matching arrangement of the screw-on groove 30 and the screw-on protrusion 40, allows for easy installation. During installation, the screw-on protrusion 40 is aligned with the screw-on groove 30, and then moved downwards to insert the pressure regulating valve assembly 4 into the installation slot 3 until the screw-on protrusion 40 passes through the screw-on groove 30. Then, the pressure regulating valve assembly 4 and the screw-on protrusion 40 are screwed together so that both ends of the screw-on protrusion 40 press against the bottom of the installation slot 3, thus completing the installation. Disassembly is performed by reversing the process. This achieves a separate installation of the pressure regulating valve assembly 4 and the pot lid 2, allowing for independent maintenance and replacement of the pressure regulating valve assembly 4, making it practical and convenient.
