[0027] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] Please refer to Figure 1-2 As shown, a pressure relief device for a pot body at least comprises:

[0029] An exhaust pipe 600, one end of which extends into the inner pot of the pot body, and the other end of which extends out of the pot body and communicates with the outside;

[0030] A pressure relief valve 700, which is located at the other end of the exhaust pipe 600 and can move on the exhaust pipe 600 to block or open the other end of the exhaust pipe 600;

[0031] The lifting structure 800 is connected to the pressure relief valve 700 and is used to push the pressure relief valve 700 .

[0032] The present application uses a lifting structure to push the pressure relief valve away from the exhaust valve, thereby connecting the exhaust valve to the outside for exhaust, and then replacing the solenoid valve. It can also greatly reduce the size of the device, increase adaptability to the working environment, and be more reliable and durable.

[0033] In this embodiment, the jacking structure 800 includes:

[0034] Lifting the base 801;

[0035] The lifting cover 802 cooperates with the lifting base 801 and has a limiting movable part 803;

[0036] A push rod 804, provided on the limit movable portion 803, for lifting the pressure relief valve 700;

[0037] The lifting driving part 805 is located on the lifting base 801 and is provided with a guiding inclined surface 806 . The lifting rod 804 is located on the guiding inclined surface 806 . As the lifting driving part 805 works, the guiding inclined surface 806 is used to lift the lifting rod 804 .

[0038] Since the push rod is limited by the limiting movable part, it can only move up and down. Under the rotation of the lifting drive part, the slope of the guide slope is used to push the push rod up and down. When it is pushed upward, the pressure relief valve can be pushed away from the exhaust pipe, thereby opening the exhaust. When it moves downward, the pressure relief valve approaches the exhaust valve through gravity, thereby blocking the exhaust pipe.

[0039] In this embodiment, the lifting structure 800 further includes:

[0040] The outer periphery of the jacking driving part 805 is provided with a rack, the rack is meshedly connected with a driving wheel 807, and the driving wheel 807 is connected with a driver 808;

[0041] The lifting driving part 805 is rotatably disposed on the lifting base 801, and the guiding inclined surface 806 is disposed around the outer periphery of the lifting driving part 805 and is designed in a sloped shape;

[0042] The driver works, driving the driving wheel and then driving the jacking drive part to rotate, and then the guide inclined surface of the slope type design is used to drive the jacking rod to move up and down.

[0043] In this embodiment, the push rod 804 is provided with a limit stopper 809 that cooperates with the limit movable portion 803 to prevent the push rod from falling off.

[0044] In this embodiment, a spring 810 is provided between the shaft of the push rod 804 and the inner cavity of the limit movable portion 803, and the push rod is reset by the action of the spring when it falls.

[0045] In this embodiment, the lifting base 801 is provided with a first micro switch 811 in the positive direction of rotation of the lifting drive part 805, and a second micro switch 812 is provided in the reverse direction of rotation of the lifting drive part 805 to prevent the lifting drive part from excessive rotation and causing the lift rod to disengage from the guide inclined surface.

[0046] In this embodiment, the upper end of the pressure relief valve 700 is provided with an insertion portion 701 for inserting into the port of the exhaust pipe 600 for blocking. The insertion portion 701 is used to insert into the port of the exhaust pipe for blocking. Conversely, exhaust is performed when the pressure relief valve is detached.

[0047] In this embodiment, the pressure relief valve 700 is located on the outer side of the insertion portion 701 and is provided with an air outlet 702 which is communicated with the exhaust pipe 600 .

[0048] The above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application. Other principles and basic structures that are the same or similar to those of the present application are within the protection scope of the present application.
