The invention relates to a method for preventing spillover of an electric cooker. The electric cooker comprises a pan body, a liner and a cover body, wherein a hard orifice plate is fixedly mounted on the lower surface of the cover body, a defoaming plate is mounted between the hard orifice plate and the cover plate, defoaming needles made of a ferro-magnetic material are arranged on the defoaming plate in an array at an equal interval, and the defoaming needles can vibrate in a vertical direction; a driving reticular plate made of a permanent magnetic material is installed inside the cover body; the driving reticular plate is parallel to the defoaming plate and can slide up and down along the inner side wall of the cover body; a vent hole is formed in the upper surface of the cover body, an exhaust baffle plate is mounted on the vent hole and can move up and down along the axial line of the vent hole; and the exhaust baffle plate and the driving reticular plate are connected via a connecting rod. The electric cooker disclosed by the invention has an elaborate structure, is convenient for cleaning, and can effectively deform to prevent spillover of rice and soup.

The present invention discloses one kind of computer lock device including one lock shell unit, one lock buckle unit, one lock head unit and one lock chain unit. The lock shell unit has one circular seat and one ring on the seat; the lock buckle unit has two cross oscillating hooks in a through hole and one elastic piece to make the hooks close each other; the lock head unit has one lock body fixed inside the circular seat and one lock core rod capable of turning between one locking position and one unlocking position; and the lock core rod has its end stretched beyond the lock body and defining one long shaft and one short shaft. In the unlocking position, the lock core rod has its end separated from two lock hooks; while in the locking position, the lock core rod end pushes these lock hooks outwards for separating. The computer lock device has convenient use and good look.

The invention discloses a widenable circular rotating dining table which comprises a circular main table surface and an annular table surface, wherein the circular main table surface is arranged on a table rack; the annular table surface can be widened; the annular table surface comprises sector table surfaces in uniform division of circle; the sector table surfaces are mounted below the table rack through a push-pull turning mechanism; the push-pull turning mechanism comprises inserted push-pull shafts and push-pull shaft sleeves; each push-pull shaft is arranged on one side of a corresponding sector table surface; guide pins on the push-pull shafts are arranged in U-shaped variation grooves formed in the push-pull shaft sleeves in a sliding manner; the U-shaped variation grooves consist of long grooves and short grooves which are formed in the outer end parts of the push-pull shaft sleeves and are communicated with each other; central angles of 90 degrees are formed between the long grooves and the short grooves; the positions of the inner ends, in the long grooves, of the guide pins correspond to vertical folding positions of the sector table surfaces; the positions of the inner ends, in the short grooves, of the guide pins correspond to horizontal widening positions of the sector table surfaces; in the horizontal widening positions, support components for bearing force of the sector table surfaces are arranged below the table rack. The area of the widenable circular rotating dining table is not increased when being folded, and the situation that the too much space is occupied by the large unfolded widenable circular rotating dining table can be avoided.
