Abstract

The utility model relates to an electric rice cooker cover opening buffer structure, comprising a cooker body with an opening at the top surface, a cooker cover which covers on the opening of the cooker body, and a pair of hinge springs which are arranged on a hinge shaft and used for braking the opening of the cooker cover, wherein the cooker cover is composed of a surface cover and an inner cover; the inner cover of the cooker cover is hinged with the hinge shaft which is supported on the cooker body in a retractable manner; two ends of the hinge springs are respectively clamped on the cooker body and the inner cover of the cooker cover; hinge shaft mounting ribs at two sides of the inner cover of the cooker cover are concave to form an embedding groove with a fixed through hole; and the embedding groove is internally provided with a buffer block which penetrates through the through hole and is used for increasing the friction force of the cooker cover relative to the cooker body so as to slow down the opening speed of the cooker cover when rotating along with the inner cover.

Description

The electric cooker buffer structure of uncapping

[technical field]

The utility model relates to electrical home appliances, is specifically related to the electric cooker buffer structure of uncapping.

[background technology]

The electric cooker of existing market generally comprises pot body, pot lid, and hinged through rotating shaft between pot lid and pot body, several torsion springs are passed in rotating shaft; Its two ends are stuck in pot body draw-in groove, and the two ends external part of several torsion springs is stuck on pot body and pot tegmental wall, and the another side of pot lid is provided with cap-opening mechanism; During use; Press the button of cap-opening mechanism, pot covers under the effect of torsion spring and flicks, and is very convenient.But there is the problem of aspects such as material in the speed that flicks of pot lid fully by the elastic force decision of torsion spring in this structure because of torsion spring, and Chang Yi causes torsion spring elastic force excessive; The user is opening pot when cover, and pot covers and flicks excessive velocities, causes electric cooker not steady; And hurt sb.'s feelings easily, security reliability is not high.Existing buffer gear generally adopts plastics and metal clips contact friction, because plastics and metal friction are easy to cause plastics contact surface abrasion or distortion to cause buffer invalidation after work a period of time, influences its service life.

[utility model content]

The utility model provide a kind of simple in structure, reliability is high, effectively slow down pot lid electric cooker of speed, the durable wear buffer structure of uncapping of uncapping.

For realizing above-mentioned purpose, the technical scheme that the utility model adopts is:

The electric cooker buffer structure of uncapping; Comprise the end face opening pot body, cover pot lid of the end face peristome of said pot body; And the hinge spring that a pair ofly is installed on the said hinge axis, the unlatching of said pot lid is braked; Pot lid is divided into cover and inner cap, and the inner cap of pot lid is with the hinge axis of folding mode hinged support on said pot body; Said hinge spring two ends be stuck in said pot body and pot lid in cover; The hinge axis installation muscle that cover one or both sides of inner cap at pot be recessed to form one have a fixed via embedding groove; Be equipped with in the embedding groove one pass fixed via and be used to when rotating increase with inner cap pot lid with respect to the frictional force of pot body, slow down the uncap buffer stopper of speed of pot lid; Buffer stopper is made up of axle shape loudspeaker oral area, thin neck, fitting portion and conical surface friction portion; The fixed via that the axle shape loudspeaker oral area of buffer stopper passes hinge axis installation muscle makes thin neck, fitting portion chimeric with fixed via and embedding groove respectively, and the conical surface friction portion of buffer stopper contacts with the jacket counter structure of pot body and produces elastic-friction power and the speed that flicks of the lid that delays to stew.

Be provided with the buckle structure that both are further engaged with the fitting portion of buffer stopper in the said embedding groove.

The advantage of this practical property:

The utility model is simple in structure; When pot lid is opened, flick, in order to slow down the speed of uncapping of pot lid through torsion spring elastic force; The hinge axis installation muscle that cover one or both sides of inner cap at pot be recessed to form one have a fixed via embedding groove; Be equipped with in the embedding groove one pass fixed via and be used to when rotating increase with inner cap pot lid with respect to the frictional force of pot body, slow down the uncap buffer stopper of speed of pot lid, the conical surface friction portion through buffer stopper contact generation elastic-friction power with the jacket counter structure of pot body, delays the speed that flicks of stewing and covering; The total stable performance, security reliability is high; Durable in use, can be adaptable across the electric cooker of various automatic lid closing/openings.

[specific embodiment]

Extremely shown in Figure 4 like Fig. 1; Present embodiment provides the electric cooker buffer structure of uncapping; Comprise the end face opening pot body 1, cover pot lid 2 of the end face peristome of said pot body 1; And the hinge spring 4 that a pair ofly is installed on the said hinge axis 3, the unlatching of said pot lid 2 is braked; Pot covers 2 and is divided into cover (not shown) and inner cap 20, and pot covers 2 inner cap 20 with the hinge axis 3 of folding mode hinged support on said pot body 1, and hinge axis 3 further installs and fixes on pot body 1 through hinge axis stator 5; Said hinge spring 4 two ends are stuck in said pot body 1 and pot and cover on 2 the inner cap 20; The hinge axis installation muscle 21 that cover 2 inner caps, 20 both sides at pot be recessed to form one have a fixed via 22 embedding groove 23; Be equipped with in the embedding groove 23 one pass fixed via 22 and be used to when rotating increase with inner cap 20 pot cover 2 frictional force with respect to pot body 1, slow down stew cover 2 uncap speed buffer stopper 6; Buffer stopper 6 is made up of axle shape loudspeaker oral area 60, thin neck 61, fitting portion 62 and conical surface friction portion 63; The axle shape loudspeaker oral area 60 of buffer stopper 6 passes hinge axis and the fixed via 22 of muscle 21 is installed is made thin neck 61, fitting portion 62 chimeric with fixed via 22 and embedding groove 23 respectively, and the conical surface friction portion 63 of buffer stopper 6 contacts generation elastic-friction power and 2 the speed that flicks of covering that delays to stew with jacket 10 counter structures of pot body 1.

As shown in Figure 3, be provided with the buckle structure 7 that both are further engaged with the fitting portion of buffer stopper 6 in the said embedding groove 23.

When uncapping; Pot covers 2 to be opened under the elastic force effect of hinge spring 4 automatically, and pot covers 1 drive buffer stopper 6 and rotates synchronously, reaches certain angle when pot covers 2; The conical surface friction portion 63 of buffer stopper 6 contacts with the jacket counter structure of pot body 1, produces elastic-friction power and 2 the speed that flicks of covering that delays to stew.

Certainly, the utility model relates to the rotating shaft installation muscle that covers one or both sides of stewing can be provided with two or more embedding grooves and buffer stopper, and the corresponding jacket of going up pot body is provided with two or more rubbing surfaces increase frictional force.In a word, doing conspicuous change according to the prompting of the foregoing description, and other every changes that do not break away from the utility model essence, all should be included within the described scope of claim.
