Abstract

The utility model belongs to the technical field of electric pressure cookers and discloses a pot cover of an electric pressure cooker. The pot cover comprises a middle cover and an inner cover which are connected in a relatively rotating mode. A handle is connected on the middle cover in a pivot mode and connected with a poking fork. A poking rod is arranged on the inner cover. A through hole is formed in the poking fork, and the poking rod penetrates through the through hole. A locating groove is formed in the middle cover. A clamping plate which can slide opposite to the poking fork is arranged on the poking fork and in connection with an elastic element. A protruding block is arranged on the clamping plate and clamped into the locating groove. A via hole and an inclined plate are arranged on the clamping plate. The poking rod penetrates through the via hole and is abutted against the inclined plate and forces the clamping plate to slide. After the poking rod is abutted against the inclined plate, the protruding block is separated from the locating groove. According to the pot cover of the electric pressure cooker, after the inner cover is dismantled, the poking fork and/or the handle cannot rotate, a situation of mistake power-on is avoided, and potential safety hazards are eliminated.

Description

A kind of pot cover of electric pressure cooking saucepan

Technical field

The utility model belongs to the electric pressure cooking saucepan technical field, especially relates to a kind of pot cover of electric pressure cooking saucepan.

Background technology

A variety of electric pressure cooking saucepans are arranged on the market, but its pot cover consists essentially of successively enclosing cover, middle cover, the inner cap of fit, wherein enclosing cover and middle cover are generally and are fastened and connected, inner cap and middle cover are rotationally connected, and inner cap can rotate and realize the effect that the pot tooth fastens with interior pot to reach middle cover and pot body fastening.In order to realize the rotation of inner cap special angle, in cover deep-slotted chip breaker be set, interior covering driving lever is set, driving lever is mobile in deep-slotted chip breaker, has so just limited the anglec of rotation of inner cap.For easy to operate, pot cover is provided with rotary handle, and handle is connected with shift fork, and shift fork and driving lever are rotationally connected, and swing handle just can drive the inner cap rotation and can only rotate a specific angle like this.

This type of electric pressure cooking saucepan generally can design inductive switch on the rocking link of handle or inner cap, only have inductive switch to detect to rotate in place the rear energising that just allows.The inner cap of existing electric pressure cooker cover generally can be designed to dismountable for easy to clean, but can be with the problem of serving like this, as: after inner cap is pulled down, handle still can rotate, if the user rotate in place handle because of carelessness, this moment, electric pressure cooking saucepan allowed energising, so just had certain potential safety hazard.Also may make the inner cap setting angle not right when inner cap is installed in addition, cause the problems such as closing lid difficulty.

The utility model content

In order to solve above-mentioned the deficiencies in the prior art, the utility model has designed a kind of pot cover of the electric pressure cooking saucepan that handle can't rotate after inner cap is removed.

The technical solution of the utility model is: a kind of pot cover of electric pressure cooking saucepan, comprise the middle cover (1) and the inner cap (2) that relatively rotate connection, be articulated with handle (3) on the middle cover (1), handle (3) is connected with shift fork (4), inner cap (2) is provided with driving lever (21), shift fork (4) is provided with through hole (41), and driving lever (21) passes through hole (41); Middle cover (1) is provided with locating slot (11), above-mentioned shift fork (4) is provided with the relatively clamp (5) of shift fork (4) slip, clamp (5) is connected with flexible member (6), and clamp (5) is provided with projection (51), and projection (51) snaps in the locating slot (11); Also be provided with via hole (52) and swash plate (53) on the clamp (5), driving lever (21) passes via hole (52) and withstands on the swash plate (53), and forces clamp (5) to slide, and after driving lever (21) pushed up swash plate (53), projection (51) broke away from locating slot (11).

After inner cap in this programme (2) is removed, snap in the locating slot (11) at the elastic reaction lower protruding block (51) of flexible member (6) so that shift fork (4) and or handle (3) can't rotate; Thoroughly avoid inner cap (2) to pull down the situation of rear mistake energising, eliminated potential safety hazard.After inner cap (2) was installed, driving lever (21) withstood on the swash plate (53), forced clamp (5) to slide, and finally made projection (51) break away from locating slot (11), and shift fork (4) can rotate; Break away from locating slot (11) before at projection (51), shift fork (4) can't rotate, and this has guaranteed the accuracy of inner cap (2) setting angle to a certain extent.

As further improvement, above-mentioned flexible member (6) is spring, and spring one end is connected on the shift fork (4), and an end is connected on the clamp (5).

As further improvement, pot cover also comprises enclosing cover, and handle (3) passes enclosing cover and middle cover (1) articulates.

The utility model compared with prior art mainly has following beneficial effect: inner cap (2) pull down rear shift fork (4) and or handle (3) can't rotate, avoided the situation of mistake energising, eliminated potential safety hazard; And guaranteed to a certain extent the accuracy of inner cap (2) setting angle.

The specific embodiment

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

Such as Fig. 1, Fig. 3 and shown in Figure 5, a kind of pot cover of electric pressure cooking saucepan comprises the enclosing cover (not shown), relatively rotates middle cover 1 and the inner cap 2 of connection.

Handle 3 passes enclosing cover and middle cover 1 articulates, and handle 3 is connected with shift fork 4, and inner cap 2 is provided with driving lever 21, and shift fork 4 is provided with through hole 41, and driving lever 21 passes through hole 41.

Middle cover 1 is provided with locating slot 11, and shift fork 4 is provided with the relatively clamp 5 of shift fork 4 slips, and clamp 5 is connected with spring 6, and spring 6 other ends are connected on the shift fork 4.

Clamp 5 is provided with projection 51, and projection 51 snaps in the locating slot 11; Also be provided with via hole 52 and swash plate 53 on the clamp 5, driving lever 21 passes via hole 52 and withstands on the swash plate 53, and forces clamp 5 to slide, and after driving lever 21 pushed up swash plate 53, projection 51 broke away from locating slot 11.

As shown in Figures 2 and 3, after the inner cap 2 in the present embodiment is removed, snap in the locating slot 11 at the elastic reaction lower protruding block 51 of spring 6, so that shift fork 4 and handle 3 can't rotate; Thoroughly avoid inner cap 2 to pull down the situation of rear mistake energising, eliminated potential safety hazard.

As shown in Figure 4 and Figure 5, after inner cap 2 was installed, driving lever 21 withstood on the swash plate 53, forced clamp 5 to slide, and finally made projection 51 break away from locating slot 11, and shift fork 4 can rotate; Before projection 51 broke away from locating slot 11, shift fork 4 can't rotate, and this has guaranteed the accuracy of inner cap 2 setting angles to a certain extent.
