They are upgraded products of traditional pressure cookers and electric rice cookers.

[0003] The electric pressure cooker has a pressure limiting valve, which is pressed at the outlet of the exhaust passage of the exhaust pipe by its own weight. When the pressure in the cooking chamber exceeds a preset value, the pressure limiting valve will be lifted by the gas in the cooking chamber, so that the pressure limiting valve avoids the outlet of the exhaust passage of the exhaust pipe, thereby releasing part of the gas, and preventing the danger caused by excessive pressure in the cooking chamber. In addition, the user can also actively make the pressure limiting valve avoid the outlet of the exhaust passage of the exhaust pipe, so as to discharge the gas in the cooking chamber.

[0004] In the art, the pressure limiting valve can have different working states, such as a pressureless state (i.e., an exhaust state), a pressure state, etc., so that the pressure cooker can cook different types of dishes. In specific use, the user can control the pressure limiting valve to be in different working states by operating the operating part provided on the cover body.

[0052] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0053] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0054] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0055] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
