Description
Technical field
The present invention is a kind of pressure cooker, and particularly electric pressure cooking saucepan is covered in a kind of button folding, belongs to the improvement technology of electric pressure cooking saucepan.
Background technology
What most electric pressure cooking saucepan adopted on the market is the mode of rotation opening closing lid; its operation is complexity and the indication putting in place without clear and definite closing lid and relevant protection comparatively; user tends to maloperation, is not having hub cap to produce the security incidents such as quick-fried pot to fastening completely or uncap by force etc. under maloperation.
Along with updating of electric pressure cooking saucepan technology, on market, there is button folding lid electric pressure cooking saucepan, as Chinese Patent Application No. 200820044330.0 discloses a kind of push button type opening and closing pressure cooker, by button pressed downwards seesaw, utilize the jack at seesaw two ends to coordinate with the inserted sheet that left and right interlock slide block tilts, utilize seesaw to swing up and down and make jack and inserted sheet relative sliding and produce horizontal component and drive left and right interlock slide block to move, thereby control closing or opening and realize the fastening of lid or open of folding ring.Although said structure can be realized the fastening of lid or open, but because being utilizes the jack at inserted sheet that left and right interlock slide block tilts and seesaw two ends to be slidably matched to drive left and right interlock slide block to move, there is larger frictional force in the hole wall of jack and the inserted sheet of inclination, therefore need to adopt larger masterpiece just can press seesaw for button, even inserted sheet and jack there will be stuck phenomenon, and causing cannot folding lid.
Summary of the invention
The object of the invention is to overcome at least one the deficiency described in above-mentioned prior art, provide a kind of laborsaving, folding to cover reliable button folding lid electric pressure cooking saucepan.
In order to achieve the above object, the technical scheme that the present invention takes: a kind of button folding lid electric pressure cooking saucepan, comprise pot body and cover the lid in pot body upper end open, pot body comprises outer pot and is placed in the interior pot in outer pot, between the inner side edge edge of lid and the pot mouthful edge of interior pot, be provided with seal ring of pot cover, on lid, be also provided with the open-and-close mechanism that is driven lid folding by operating-controlling mechanism, described open-and-close mechanism comprises first, two profiles, first, two braces, first, two profiles are installed on respectively the outer edge on lid both sides, first, two braces be placed in lid above, one end of the first brace is connected with the first profile, the other end of the first brace is provided with the first tooth bar, one end of the second brace is connected with the second profile, the other end of the second brace is provided with the second tooth bar, the first brace is provided with the middle part that one end of the first tooth bar and one end that the second brace is provided with the second tooth bar lay respectively at lid, the edge of the upper end of outer pot is corresponding first, the position of two profiles is provided with button platform, first, two profiles can with the button platform snapping of outer pot, described operating-controlling mechanism comprises the support at the middle part that is installed on lid, be installed on the seesaw on support, seesaw is provided with respectively first and second gear with the first tooth bar and the engagement of the second tooth bar, seesaw is placed on the dead eye on support and can swings with the bolster at its middle part, and when seesaw swings, can drive the first brace, the first profile and the second brace, the second profile near or away from the middle part direction of lid, move, make the button platform snapping of first and second profile and outer pot or separated.
In such scheme, by first and second gear on seesaw respectively with first and second brace on first and second profile mesh, seesaw drives first and second gear to rotate and drives first and second tooth bar while swinging, thereby drive the first brace, the first profile and the second brace, the second profile simultaneously near or away from the middle part direction of lid, move, make the button platform snapping of first and second profile and outer pot or separated, realize the fastening of lid or open.
Further, above-mentioned first and second gear lays respectively at downside and the upside of seesaw, the first tooth bar is positioned at the below of seesaw, the second tooth bar is positioned at seesaw top, the first tooth bar engagement of the first gear and seesaw below, the second tooth bar engagement of the second gear and seesaw top, can drive first and second gear to rotate and drag first and second tooth bar when seesaw swings up and down.
In order to guarantee first and second brace smooth sliding, the dual-side at corresponding first and second brace above above-mentioned lid is provided with compressing tablet.
For fear of pot body internal gas pressure, do not drop to safe range and pot cover is opened in maloperation, above-mentioned lid offers steam vent in the position of corresponding the first brace or the second brace, the first brace or the second brace offer lockhole, in steam vent, be provided with the float that can move up and down, and float can pass lockhole.
In order realizing, automatically to make the button platform snapping of profile and outer pot or separated when seesaw swings certain angle, between above-mentioned seesaw and support, to be connected with spring, the junction of the junction of spring and seesaw and spring and support lays respectively at the both sides of the bolster of seesaw.
In order conveniently to carry pot cover or to press seesaw, position at corresponding operating-controlling mechanism on above-mentioned lid is provided with handle, on handle, offer first and second button fixing hole, in first and second button fixing hole, be respectively equipped with first and second button, first and second button lays respectively at the top of seesaw, and the lower end of the lower end of the first button and the second button can contact with the both ends of seesaw respectively.
For after realizing button and being pressed, can automatically reset, above-mentioned first and second button outside is respectively installed with back-moving spring.
For attractive in appearance, above-mentioned lid is provided with upper cover above corresponding the first brace and the second brace, and the lower end of handle is fixed on and covers.
For first and second profile is coordinated with the outer edge on lid both sides, above-mentioned first and second profile is circular-arc, and the shape of cross section of first and second profile is U-shaped, and first and second profile is with the button platform snapping of its lower end wall portion and outer pot.
For the steadiness that guarantees that pot cover fastens, above-mentioned first and second profile is symmetrically placed in the outer edge on lid both sides.
The present invention is owing to adopting the kind of drive of wheel and rack engagement, while swinging by seesaw, drive first and second gear to rotate and drive first and second tooth bar, thereby drive the first brace, the first profile and the second brace, the second profile simultaneously near or away from the middle part direction of lid, move, make the button platform snapping of first and second profile and outer pot or separated, realize the fastening of lid or open, reliable transmission of the present invention, the active force that seesaw is swung is relatively existing also less, and occurs that stuck probability is less.In addition, in pot body under anticyclonic state float by jack-up, thereby brace is locked, prevent user pot body internal gas pressure do not drop to safe range and maloperation to open pot cover accidents caused, between seesaw and support, be connected with spring, realize and when seesaw swings certain angle, can automatically make the button platform snapping of profile and outer pot or separated, reduce the distance that user pushes button.
