Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

Referring to fig. 1 to 7, the utility model provides a high-pressure electric cooker, including the pot body 1, the inner bag 5 and the lid of setting in the pot body 1 close pot cover 2 on the pot body 1, pot cover 2 can rotate on the pot body 1 in order to switch between unblock position and locking position, be provided with relief valve 3 and pressure floating valve 4 on pot cover 2, pot cover 2 still is provided with separation blade 61 that can control about it, be provided with the through-hole 611 that can supply the float 41 of pressure floating valve 4 to pass on the separation blade 61, be provided with ejection mechanism between pot cover 2 and the pot body 1, ejection mechanism is with separation blade 61 roof pressure to the position that can block float 41 rebound when pot cover 2 is in between unblock position and the locking position, still be provided with the resetting means who drives separation blade 61 and reset when it rotates to the locking position on pot cover 2.

Referring to fig. 3, a sealing ring 42 is fitted over the float 41, and when the pressure in the pot is not raised, the float 41 naturally drops, the pressure float valve 4 is kept in a normally open state, and when the pressure in the pot rises to a certain level, the float 41 is pushed upward by the pressure in the pot, so that the sealing ring 42 closes the pressure float valve 4.

As the utility model discloses an optimal scheme, ejection mechanism is including connecting the ejector pin 62 in the one end of separation blade 61, and set up ejection lug 120 on the pot body 1, when the pot cover 2 switches between unblock position and locking position, ejection lug 120 roof pressure ejector pin 62 so that separation blade 61 moves to the position that can block float 41, ejection mechanism is still including setting up third ejection inclined plane 131 on the pot body 1, when the unblock position was gone into to the pot cover 2 lid, third ejection inclined plane 131 ejection pot cover 2 rotated an angle so that ejector pin 62 moves to the position by ejection lug 120 roof pressure. The ejecting lug 120 has three sides capable of ejecting the ejecting rod 62, and the three sides are respectively: a first push inclined surface 121 located at one end of the push protrusion 120, a second push inclined surface 122 located at the other end of the push protrusion 120, and a push arc surface 123 located between the first push inclined surface 121 and the second push inclined surface 122.

Due to the pushing action of the third pushing inclined plane 131, after the pot cover 2 is covered, the push rod 62 directly rotates to the position where the push rod abuts against the first pushing inclined plane 121, in the process, the first pushing inclined plane 121 pushes the push rod to axially move for a certain distance, so that the float 41 is blocked by the blocking piece 61 under the pot cover 2, and the pressure in the pot caused by mistaken touch is avoided. In the process that the pot cover 2 rotates from the unlocking position to the locking position, the ejector rod 62 slides along the first ejection inclined surface 121 → the ejection arc surface 123 → the second ejection inclined surface 122, and in the process, the baffle piece 61 moves to the position capable of blocking the floater 41 due to the ejection effect of the ejection convex block 120, so that the pressure in the pot cannot be raised even if the cooking program is started by mistake, and the situation of frying the pot is avoided; after the cooker cover 2 is rotated to the locking position, under the action of the resetting device, the blocking piece 61 is reset, the through hole 611 on the blocking piece 61 is aligned with the float 41 of the pressure floating valve 4, at the moment, the cooking procedure is started, and the cooker can be normally pressurized for cooking.

Referring to fig. 5, the end of the ejector pin 62 abutting against the ejector protrusion 120 is shaped like a hemisphere or a semi-ellipsoid, and the surface thereof is arc-shaped. The design can reduce the friction between the ejector rod 62 and the ejector lug 120, and improve the smoothness of the movement of the ejector rod 62.

The pan body 1 comprises a cylindrical outer shell 11 and a cylindrical inner shell 12 arranged in the outer shell 11, wherein the upper end of the inner shell 12 is connected with the upper end of the outer shell 11 through an annular middle ring 13. The utility model discloses an in the scheme, the outer fringe of zhonghuan 13 is provided with the ascending bellied outer lane board 130 of round, be provided with a notch 132 on the outer lane board, pot cover 2 has handle lug 23, when pot cover 2 rotates between unblock position and locking position, handle lug 23 is at the internal rotation of notch 132, third ejection inclined plane 131 sets up on a lateral wall of notch 132, another lateral wall of notch 132 can be with handle lug 23 butt in order to inject pot cover 2 in locking position, it is comparatively convenient that such structure is manufactured. Of course, the pushing projection 120 can be disposed at other positions of the pot body 1, but is not limited thereto.

Referring to fig. 2 and 3, the pot cover 2 includes an upper cover plate 21 and a lower cover plate 22, a mounting hole for mounting the pressure floating valve 4 is provided on the lower cover plate 22, the pressure floating valve 4 is fixedly mounted at the mounting hole, an exhaust hole 211 capable of allowing the float 41 to be inserted therein is provided at a position on the upper cover plate 21 right opposite to the pressure floating valve 4, a through hole 611 is provided at the head end of the blocking piece 61, the blocking piece 61 is provided between the upper cover plate 21 and the lower cover plate 22, and the head end of the blocking piece 61 is located between the pressure floating valve 4 and the exhaust hole 211, and the ejector rod 62 is connected at.

The edge of the lower cover plate 22 is bent downwards and surrounds the ejecting lug 120, a horizontal first guide hole 222 is arranged at the edge of the lower cover plate 22, and one end of the ejector rod 62 passes through the first guide hole 222 and extends to a position capable of abutting against the ejecting lug 120.
