Abstract

The utility model discloses a lid opening structure of an electric heating kettle, which pertains to the technical field of the house-hold kettles used in a kitchen; the structure is arranged on a base body of a lid; the base body of the lid is rotationally fixed to a kettle body by a torsional spring; the lid opening structure comprises a button, a front-end latch and a returning spring of the front-end latch; the bottom of the button leans against the front-end latch; the front end of the front-end latch is clipped on the kettle body when the lid is closed. The lid opening structure of the utility model is characterized in that the structure also comprises a rear-end latch, a positioning block and a returning spring of the positioning block; the returning spring is under the positioning block; the end part of the rear-end latch is against the positioning block which is arranged on a fixed base connected with the kettle body; the front-end latch and the rear-end latch move in a linkage way, which means that: when the button moves downwards, the front-end latch retracts, and the rear-end latch also retracts due to the linkage; after the rear-end latch retracts, the positioning block bounces up and leans against one side of the rear-end latch. Aiming at overcoming the defects that the lid opening structure in the prior art can not open the lid smoothly after the lid is closed and that the latches are easily clipped in the kettle body, the lid opening structure of the utility model provides a lid opening structure which has simple structure as well as stable self-locking and opens the lid easily and smoothly.

Description

The cover-opening structure of kettle lid of electric heating kettle

Technical field

The utility model belongs to household kitchen water cooking appliance technical field, is specifically related to a kind of open and close cover structure of kettle lid of electric heating kettle.

Background technology

Wireless insulating pot is as a kind of emerging kitchen small household appliances, with its flames of anger, and thermal efficiency height, advantage such as speed is quick is popularized very soon.

In the prior art, the cap-opening mechanism of electric kettle mainly is made up of pot lid pedestal and the button that is positioned on pot lid pedestal or the handgrip, button is slidingly connected by a push rod or inclined-plane and snap close, rely on spring control return, the pot lid seat is fixed on position, kettle handgrip upper support hole by torsion spring, when latching in the pot lid closure, the front end of snap close stretches out the lower surface that is buckled in kettle body holder from the pot lid pedestal; When needing to open, button pressed downwards, the snap close retraction breaks away from kettle body holder, and the pot lid pedestal relies on the power of torsion spring to open.But the pot lid of kettle flicks mechanism and often has bullet and do not open or open a part of phenomenon in being to use; now in the technology head it off method for increasing the uncap intensity of spring of pot lid; but the increase of spring strength makes the dynamics of uncapping when uncapping increase; the globule of pot lid can splash out when uncapping and scald the client, makes troubles in use for the client in use.

Summary of the invention

Exist button to press the shortcoming that some was not opened or opened to back pot lid bullet for solving existing cap-opening mechanism, it is a kind of simple in structure that the utility model provides, and pot lid is opened the cover-opening structure of kettle lid of electric heating kettle smoothly.

For realizing the utility model purpose by the following technical solutions:

The cover-opening structure of kettle lid of electric heating kettle, be installed on the pot lid pedestal of pot lid, the pot lid pedestal is fixed in the kettle body by the rotation of button spring, described cover-opening structure comprises button, front end snap close and front end snap close back-moving spring, the front end snap close is replaced in the button bottom, the front end of front end snap close is stuck on the kettle body when pot lid fastens, it is characterized in that also comprising the rear end snap close, locating piece and the locating piece locating piece back-moving spring under it, locating piece is replaced in the end of rear end snap close, locating piece is installed on the holder that is connected with the kettle body, front end snap close and the interlock of rear end snap close, promptly when button moved down, front end snap close retraction interlock rear end snap close bounced back, and rear end snap close retraction back locating piece can be upspring and be leaned the return that snap close one side in rear end stops the rear end snap close, this moment, the front end snap close broke away from the screens zone of kettle body, and the torsion of torsion spring is opened pot lid.

The utility model operation principle is: by the conversion of spring force, button front end snap close and rear end snap close when pressing down can shrink simultaneously and form a self-locking mechanism, the rear end latches in contraction when touching the button downwards, locating piece on this moment kettle body is upspring and is blocked the rear end snap close and do not allow its resilience, by the torsion of torsion spring pot lid is opened;

After flicking, front end snap close and rear end snap close have been thrown off the limited position of locating piece on the kettle body, and the locating piece on forward and backward snap close and the kettle body also will self-return simultaneously.

Pot lid can be run into locating piece on the kettle body closing rear end snap close when covering process, the rear end snap close can be forced the locating piece on the kettle body to lower compression, the front end snap close can eject to fastening the position automatically along the evagination face retraction of kettle body, guarantees that pot lid can not automatically spring open under the situation that is not subjected to external force.

Further, front end snap close and rear end snap close are by transmission levers interlock, and transmission levers rotates around a fixed axis.

Button in the utility model can force in the front end snap close as button by the inclined-plane for several usual ways of the prior art with being connected of front end snap close, and promptly the contact-making surface of button or front end snap close includes guiding surface; Can establish the inclined-plane on the front end snap close, button is that the inclined-plane leads; Also can pass through drive link, perhaps pass through sliding piece, be not limited to shrink under the button front end snap close on time, drive the retraction of front end snap close in the time of can be for button rotation, optimal way is that described button lower end comprises two place's guiding surfaces, the front end snap close comprises two corresponding guiding surfaces, and the button lower end is provided with back-moving spring.

Further improvement of the utility model, the contact-making surface of described rear end snap close and locating piece include one section arc, and the action of upspringing of locating piece was clear-cut under arc helped.

The utility model insulating pot compared to existing technology mode of uncapping owing to adopt front end snap close and rear end snap close and cooperate locating piece to form from contracting, is avoided the problem of uncapping effort and not opening when opening, it is smooth and easy that insulating pot is uncapped.
