Embodiment Construction
[0028] The present invention will be further described below in conjunction with the accompanying drawings.
[0029] Such as figure 1 , figure 2 As shown, an electric pressure cooker with an improved sealing ring includes a pot body 1, a pot cover 2, a sealing ring 3, a pressure sensor 4 and a lock 5 arranged on the pot cover 3; the upper opening of the pot body 1 has a The outer folding edge 11; the outer folding edge 11 has a vertical coaming board, and the gap between the vertical coaming board and the pot body 1 forms a card slot.
[0030] The pot cover 2 includes a top plate 21 and a surrounding plate 22, and a positioning device is arranged on the top plate 21 of the pot cover 2;
[0031] Such as image 3 As shown, the sealing ring 3 includes an inner annular ring 31, an elastic support plate 32 pre-embedded in the inner annular ring, a lower groove 33 located radially outside the inner annular ring 31, and a level mirrored with the lower groove 33. The clamping gro...

The invention discloses an electric pressure cooker with an improved seal ring. The electric pressure cooker comprises a pot, a pot cover, a seal ring, and a pressure sensor and a lock catch which are arranged on the pot cover; the electric pressure cooker is characterized in that a deflexed edge is formed on an upper opening of the pot; the pot cover comprises a top plate and peripheral plates, and a location device is arranged on the top plate of the pot cover; the seal ring comprises an inner ring circle, an elastic support plate embedded in the inner ring circle, a lower groove located atradial outside of the inner ring circle, and a horizontal clamping groove arranged in mirror image with the lower groove; the horizontal clamping groove is matched with the location device on the topplate, and the lower groove and the external wall of the horizontal clamping groove are attached to the peripheral plates of the pot cover; and the upper opening and the deflexed edge of the pot are embedded into the lower groove. With the elastic support plate, an axial lower end of the seal ring is closely attached to the pot, and simultaneously, the pot cover tightly compresses the seal ring under the function of the lock catch so as to prevent the seal ring from deformation and maintain excellent sealing performance.
Description
technical field [0001] The invention relates to an electric pressure cooker. Background technique [0002] In the current prior art, a voltage cooker includes a main body, a pressure sensor arranged on the main body, an electric heater and a control device. The main body includes a pot body, a pot cover and a sealing ring, and the pot body and the pot cover are fastened by a lock; The pressure sensor is in communication with the control device. Existing problems are: the sealing ring is easily deformed, the service life of the sealing ring is short, the sealing ring is not tightly sealed, and air leakage occurs. Contents of the invention [0003] The object of the present invention is to provide an electric pressure cooker with an improved sealing ring, which can prolong the service life of the sealing ring and ensure sealing without air leakage. [0004] The present invention is achieved in the following way: an electric pressure cooker with an improved sealing ring, in...
