The pressure limiting valve 22 is a conventional structure in the art and will not be described in detail here. The float valve 21 passes through the pot cover 2 and the upper handle 4 upwards, and the float valve is also a conventional structure in the art and will not be described in detail here. The upper handle 4 is provided with a slidable locking arm 5. After closing the lid, the pot cover 2 cannot be opened under the action of the locking arm 5. When opening the lid, the locking arm 5 slides inward and then rotates to open the pot cover 2. This is a prior art, such as the technical solution disclosed in Chinese invention patent application CN110292305A.

[0035] In the present invention, the upper handle 4 is detachably mounted on the pot cover 2. The upper handle 4 can be removed after the cover is opened, and it is convenient to clean the pot cover 2 and the upper handle 4 after the upper handle 4 is removed, and the cleaning effect is better when the pot cover 2 and the upper handle 4 are cleaned separately.

[0036] In this embodiment, the upper handle 4 is detachable in the following manner: a locking plate 6 is provided inside the upper handle 4, one end of the locking plate 6 is connected to an elastic member 7 located inside the upper handle, the elastic member 7 is generally a tension spring, and a locking hook 8 is provided at the other end. The locking plate 6 has a tendency to move inward under the action of the elastic member 7, and the locking hook 8 hooks the edge of the pot cover 2 after the cover is closed.

[0037] The upper handle 4 is also provided with a driving mechanism for overcoming the force of the elastic member, thereby driving the locking plate 6 to move outward. After the lid is opened, the driving mechanism drives the locking plate 6 to move outward, and the locking hook 8 is separated from the edge of the pot cover 2, so that the upper handle 4 can be removed. In this embodiment, the edge of the pot cover is also provided with a fixing plate 9, and the fixing plate 9 is provided with a locking hole 10.
