[0002] With the continuous improvement of living standards, electric pressure cookers have become indispensable household appliances in people's daily lives. At present, the exhaust valves of electric pressure cookers sold on the market only have two functions: sealing and exhausting. During daily use, many consumers have reported that when cooking rice under high pressure, the rice does not boil, and the cooked rice is mostly soft and mushy in the middle, with poor results, uneven hardness of the rice grains, and bad taste, resulting in a poor user experience. Content of the Utility Model

[0003] The utility model aims to overcome the deficiencies in the above-mentioned prior art and provides a multi-functional exhaust valve for an electric pressure cooker.

The multi-functional exhaust device includes an exhaust pipe, an exhaust valve assembly, and a valve handle for rotating the exhaust valve assembly. The exhaust pipe is installed in the first cavity of the valve handle. The exhaust valve assembly is cooperatively installed with the valve handle and is located above the exhaust pipe to open and seal the exhaust pipe. The valve handle is rotatably connected to the pot lid, and the rotation of the valve handle relative to the pot lid can complete various working states of the multi-functional exhaust device.

[0005] Through the setting that the valve handle is rotatably connected to the pot lid, the rotation of the valve handle relative to the pot lid can complete three working states of high pressure, low pressure, and exhaust of the multi-functional exhaust device. That is to say, the exhaust valve assembly is driven by the valve handle to act correspondingly, and the opening and sealing of the exhaust pipe are realized through the action of the exhaust valve assembly, so as to complete various working states.

[0006] Preferably, the rotation of the valve handle relative to the pot lid can complete the states of high pressure, low pressure, and exhaust; or the states of sealing and exhaust. The rotation of the valve handle relative to the pot lid at different positions can realize the states of high pressure, low pressure, and exhaust; or the states of sealing and exhaust.

[0007] Preferably, the bottom of the exhaust pipe sequentially penetrates the bottom of the valve handle and the bottom of the pot lid, and the electric pressure cooker is provided with a first fixing member for fixing the bottom of the exhaust pipe. The setting that the bottom of the exhaust pipe sequentially penetrates the bottom of the valve handle and the bottom of the pot lid allows the gas in the electric pressure cooker to be discharged from the exhaust pipe as needed, so as to complete various cooking states. The setting that the electric pressure cooker is provided with a first fixing member for fixing the bottom of the exhaust pipe is to reliably fix the exhaust pipe on the pot lid.

[0008] Preferably, the exhaust valve assembly includes a valve body cover, a valve body ring, and a valve body. The valve body ring is sleeved outside the valve body.

The heat preservation cover 61 is sleeved outside the inner pot 62, and the heating plate 63 is arranged in the heat preservation cover 61 and at the bottom of the inner pot 62.

[0045] Specific working principle:

[0046] During operation, rotate and snap the pot lid 4 onto the pot body 6, and the cooking state can be selected according to requirements. For example, when using the low-pressure rice cooking function, rotate the valve handle 3 to the low-pressure function, and the valve handle 3 drives the valve body ring 22 to move upward. At this time, the boss 32 at the bottom of the valve handle 3 is stuck at the first groove 42 of the pot lid 4, and only the weight of the steel valve body 23 and the exhaust pipe 1 are sealed. When the pressure inside the pot exceeds the weight limit value of the steel valve body 23, the steel valve body 23 will be lifted and suspended by the pressure, and the excess air pressure will be released from the nozzle of the exhaust pipe 1, and the pressure value will be limited to work within a certain range.( Figure 10 as shown)

[0047] When cooking difficult-to-cook foods, select the high-pressure function. At this time, the weight of the valve body ring 22 and the steel valve body 23 are relied on to seal the cooking with the exhaust pipe 1, and the pressure value will be twice that of the low-pressure function, so as to realize the high-pressure cooking function.( Figure 9 as shown)

[0048] When the operation is over and you want to quickly take out the food in the pot, you can rotate the valve handle 3 to the exhaust state of the pot lid 4. At this time, the exhaust valve assembly 2 moves upward, and the tapered thimble 231 of the exhaust valve body 23 is separated from the nozzle of the exhaust pipe 1, and the steam quickly releases the pressure from the nozzle. After the pressure is released, you can quickly take out the food in the pot.( Figure 11 as shown).

[0049] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
