Abstract

The utility model relates to a light touch and keystroke type opening mechanism for a cover of an electric rice cooker. The utility model comprises a hollow cooker cover formed by a face cover and an inner cover, a button for opening covers, and a spring of the button. A cooker body is provided with a buckling position. The buckling position and a hook on the end part of a button lever on the button are matched to open and close the cooker over. The utility model can be affected by the deformation of the cooker body little. The utility model has the advantages of easy machining, simple assembly, and tight cover closing. The buckling position and the hook engage better. The utility model overcomes the condition that the buckling position and the hook engage tightly, and thus, the cooker cover can not be opened.

Description

A kind of electric cooker cap-opening mechanism

The utility model relates to a kind of electric cooker contact button formula cap-opening mechanism.

Existing commercially available electric cooker cap-opening mechanism has manually and two kinds of automatic lid closing/openings.The shift knob multidigit of hand is on handle, and working method mostly is button bit and hook formula, though simple in structure, manual opening cover is common in low-grade electric cooker.Chinese patent ZL89214716.4 disclosed " lid of electric cooking-vessel ", complex structure, close cover sealing effectiveness be difficult to control, poor durability, practicality is low.Self-action is more common in high-grade electric cooker, structure mostly is the hook lever type button, button is positioned at shell edge, the boss cooperating at its hook and pot cover edge, strength by extension spring is hooked or is pressed on the flat limit of L, though structure is simple, very easily is subjected to the influence generation interlock of pot body deformability to cross extremely and can't uncap, interlock is shallow excessively closes problems such as lid is not tight, has seriously influenced to sell and use.

The purpose of this utility model provides a kind of contact button formula cap-opening mechanism that overcomes above-mentioned drawback.

A kind of electric cooker touches the button cap-opening mechanism, comprises the hollow type pot cover body that cover and inner cap constitute, and has in the button of uncapping on push-button reset spring, the pot body button bit is arranged, and button bit fastens the hook of the button lever end that the button lower edge stretches out downwards.Wherein, the button of uncapping of hollow form is positioned at cover edge, and button bit is barb-like or other shapes, have under the barb upper surface can with the interlock button slide block of end in contact under the barb.The button slide block can slide in chute, and back-moving spring is arranged in it.

Button bit also can be the dustpan shape, and is anterior unsettled, and the bottom, rear end has support column to be connected with the pot body.At this moment, on the button lever end L type hook that stretches out under button lower edge one side direction an automatic folder that cooperates with dustpan shape button bit is arranged.Automatically folder to go up folder mouthful mouthful longer than folder under the L type, last folder mouth comprises interlock button slide block and is positioned at the chute of L back.Back-moving spring is arranged in the button slide block equally, and its width is less than the width of dustpan shape button bit mouth, and the width of L type hook is greater than the width of dustpan shape button bit mouth.All there is the positioning boss of a push-button reset spring inboard of the button of two kinds of schemes, in cover corresponding position also have one the location boss.

The utility model compared with prior art, novel structure, handsome in appearance, comfortable feel fastens reliable; Close lid, be attended by clear and melodious " click clatter " sound when uncapping, the user is had the prompting effect.This structure overcome effectively the common automatic lid closing/opening mechanism of electric cooker in the past because of foozle, add that the fastening that factor such as thermal deformation causes is bad, interlock is crossed dead so that the defective that can't uncap.

Below in conjunction with accompanying drawing the utility model is further described.

Accompanying drawing 1 is the cap-opening mechanism structural representation of existing commercially available prod;

Accompanying drawing 2 is that the utility model embodiment 1 closes the structural representation when covering;

Accompanying drawing 3 is embodiment 1 structural representations when uncapping;

Accompanying drawing 4 is that the utility model embodiment 2 closes the structural representation when covering;

Accompanying drawing 5 is embodiment 2 structural representations when uncapping.

Embodiment 1, with reference to accompanying drawing.Covering under the tightening state closing, uncap button 5 under the effect of push-button reset spring 6 on the cover 4, is fulcrum with the boss on the inner cap 2, and fastening forms reliable fastening and closes the state of lid on button bit 3.This moment, withstood the uncapped end of button lever 9 of button slide block 7 and its back-moving spring 8, is pressed in pot body 1, and button slide block back-moving spring is in compressive state.

In closing the process of lid, the button of uncapping protrudes outside cover under the effect of its back-moving spring.When the pot cover body falls, the end of button lever drop on gradually on the following hook inclined-plane of barb-like button bit thereupon and along under sliding, withstand button upper end of slide block face gradually, be pressed in pot body, make it to break away from and the contacting of button bit, the hook of button lever end then slips into from the gap.When pot cover cap on earth the time, the hook of button lever end also slips in the button bit fully, forms reliably to fasten.

Press the button of uncapping when uncapping, button spring is compressed, and the button of uncapping is that fulcrum is done lever motion with the interior boss that covers, and the total aft hook of button lever end breaks away from the buckling state with button bit.The button slide block then under its action of reset spring the end with button lever upwards skid off, after disengaging, just rapidly rise up to being withstood by button bit with button lever.When unclamping when uncapping button, the pressure that button is subjected to disappears, resilience under the effect of its back-moving spring, but owing to be subjected to stopping of button slide block and can not fasten in the button bit again, the state of uncapping is held, the pot cover body is upspring, is opened under the torsion spring effect.

Embodiment 2, with reference to accompanying drawing.Closing when covering fastening, button slide block 7 and its back-moving spring 8 that is in compressive state are positioned at the top of button bit 3, with the L type hook of button lever 9 ends dustpan shape button bit lockjaw are gripped.In closing the process of lid, when lid drops to certain position, the L type of button lever 9 ends is linked up with on the button bit inclined-plane that drops on pot body and is sliding under suitable, the button slide block narrower than button bit mouth stopped by the button bit lip, when pot cover cap on earth the time, L type hook has slided under the button bit lip, with the button slide block button bit lip is clamped, and forms reliably to fasten.Operation when uncapping is just the opposite, with the similar process of uncapping of embodiment 1.
