Electric pressure cooker allowing lid to be opened and closed through buttons

Abstract

The invention provides an electric pressure cooker allowing a lid to be opened and closed through buttons. The electric pressure cooker comprises a cooker body and the lid. The lid is provided with an opening and closing mechanism driven by a control mechanism to open and close the lid. The opening and closing mechanism comprises a first buckling strip, a second buckling strip, a first connection strap and a second connection strap, the first buckling strip and the second buckling strip are arranged on the outer edges of the two sides of the lid respectively, one end of the first connection strap is connected with the first buckling strip, the other end of the first connection strap is provided with a first toothed bar, one end of the second connection strap is connected with the second buckling strip, the other end of the second connection strap is provided with a second toothed bar, both the end, provided with the first toothed bar, of the first connection strap and the end, provided with the second toothed bar, of the second connection strap are located in the middle of the lid, a buckling platform is installed at the upper end of an outer cooker, and both the first buckling strip and the second buckling strip can be connected with the buckling platform of the outer cooker in a buckling mode. The control mechanism comprises a support and a swing plate, the support is installed in the middle of the lid, the swing plate is installed on the support and provided with a first gear and a second gear, and the first gear and the second gear are meshed with the first toothed bar and the second toothed bar respectively. According to the electric pressure cooker, by the adoption of the transmission mode that the gears are meshed with the toothed bars, transmission is reliable, acting force for enabling the swing plate to swing is small, and the jamming probability is very low.

Description

technical field [0001] The invention relates to a pressure cooker, in particular to an electric pressure cooker with a button opening and closing cover, which belongs to the improvement technology of the electric pressure cooker. Background technique [0002] Most of the electric pressure cookers on the market use a rotary lid opening and closing method. The operation is more complicated and there is no clear instruction for closing the lid in place and related protection. Users often make misoperations. Misoperations such as closing or forcibly opening the lid may cause safety accidents such as pot explosion. [0003] With the continuous improvement of electric pressure cooker technology, electric pressure cookers with button opening and closing lids have appeared on the market. For example, Chinese Patent Application No. 200820044330.0 discloses a button-type opening and closing pressure cooker. The rocker is pressed down by the button, and the jack at both ends of the roc...

Problems solved by technology

Although the above-mentioned structure can realize the fastening or opening of the cover body, it drives the left and right interlocking sliders to move due to the sliding fit between the inclined inserts on the left and right interlocking sliders and the jacks at both ends of the seesaw. There is a large friction force between the wall of the hole and the inclined insert, so a large force is required to act on the button to press the rocker, and even the insert and the socket may be stuck, making it impossible to open and close the cover
