Description

The pressure cooker safety that prevents maloperation is ended opening mechanism

Technical field

The utility model relates to the pressure cooker that a kind of family life is used, and especially relates to a kind of pressure cooker safety and ends opening mechanism.

Background technology

In order to guarantee the safe handling of pressure cooker, current in the design of pressure cooker, all considered release mechanism, wherein one for correctly not closing when covering when pressure cooker, do not allow in the pot to press, and when pressure is arranged in the pot (during P＞5kpa), can not open pot cover with common strength, this abbreviates only opening mechanism of safety as in the pressure cooker design.

Fig. 1 is that the cap-rotating type safety of current a kind of maturation is ended the opening mechanism scheme, and this scheme is by the handle 1 that is loaded on the pot cover, and safe stopping valve assembly 2 and the lower handle 3 that is loaded on pot body are formed.Push button 11 is housed on the handle 1, and backstay 12, apron push away post 13; Be equipped with on the safe stopping valve assembly when pot inner pressure P ≯ 5kpa, can rise only start 21; The guide groove 31 of only starting that lower handle 3 is provided with particular design reaches prominent 32.The feature of this scheme is Dang Hegai when putting in place, and prominent head makes prominent 112 hole of having aimed in the backstay column in rear portion on the push button with backstay jack-up, thus make the head of only starting on the push button snap in guide groove and locking last lower handle.When pot inner pressure rises, only start to rise and keep off front portion at push button, make push button can't push the front portion to, thereby guarantee user's safety.And reduce to 5kpa when following when pot inner pressure, only start to fall, can push push button to front portion with hand, make handle and lower handle remove lockup state, the back backstay of uncapping has broken away from prominent head, descends under the effect of spring 15, prominent head is blocked by the head of column, can't make backward and only start and to rise, play and do not close lid and put security protection effect that can not upward pressure in the pot in place.This structure is used widely because of using reliably, but there is a maloperation problem, just working as backstay is pressing under unexpected situation, push button is moved back to the rear portion, only start and to rise thereby make, this moment, pot inner pressure also may rise if upper and lower handle does not close lid to put in place, thus the potential safety hazard of causing.

Summary of the invention

The purpose of this utility model is: develop a kind of pressure cooker safety of maloperation that prevents and end opening mechanism, to prevent that working as backstay is pressing under unexpected situation, and upper and lower handle does not close lid when putting in place, and pot inner pressure also may rise, thereby causes the technical problem of potential safety hazard.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of pressure cooker safety of maloperation that prevents is ended opening mechanism, contain the upper handle that is loaded on the pot cover, safe stopping valve assembly and be loaded on lower handle on pot body, push button is housed on the upper handle, reach only starting of linking to each other with push button, on only starting, apron is housed and pushes away post, one side has backstay, it is characterized in that: described apron pushes away the other end that post contacts with apron and is provided with extension body, described extension body only passes starts, and matches with the hole on the backstay column.

The technical solution of the utility model also can be further perfect, and as preferably, the lower end of described backstay pushes away post one side near apron, is provided with to be suitable for the hole that extension body that apron pushes away post inserts.

Therefore, the beneficial effects of the utility model are: have simple in structurely, it is safe and reliable to end opening mechanism, and characteristics such as fundamentally eliminate safe hidden trouble.

Description of drawings

Accompanying drawing 1 is a kind of pressure cooker structural representation of prior art;

Accompanying drawing 2 is that the utility model closes the structural representation that covers when putting in place;

Structural representation when accompanying drawing 4 is the utility model releasing lockup state.

The specific embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.

As Fig. 2, Fig. 3, pressure cooker shown in Figure 4, by the upper handle 1 that is loaded on the pot cover, safe stopping valve assembly 2 and the lower handle 3 that is loaded on pot body are formed.Push button 11 is housed on the handle 1 and coupled only starts 111, prominent 112 at rear portion and push button spring 14 are only started apron to be housed on 111 and are pushed away post 13 and extension body 131 thereof; There is backstay 12 only start 111 side, and the column 121 that contains hole is arranged at backstay top, and there is the hole 122 that adapts with the extension body diameter extension body 131 corresponding positions that backstay lower end and apron push away post, and backstay spring 15 is arranged on the backstay 12; Be equipped with on the safe stopping valve assembly 2 when pot inner pressure P ≯ 5kpa, can rise only start 21; There is the guide groove 31 of only starting of particular design to reach prominent 32 on the lower handle 3.

During use, put in place when closing lid, see Fig. 2, prominent 32 with backstay 12 jack-up, make the hole in prominent 112 column of having aimed on the backstay 12 121 in rear portion on the push button 11, thereby push button 11 only start 111 head under the effect of push button spring 14, snap in guide groove 31 and locking upper and lower handle; When pot inner pressure rises, only start 21 can rise and keep off, make push button 11 can't push the front portion to, make and only start 111 to break away from guide grooves 31 in the front portion of push button 11, thereby can't remove the lockup state between upper handle 1 and the lower handle 3 and can not uncap, thereby guarantee user's safety; And reduce to 5kpa when following when pot inner pressure, only start 21 to fall, can push push button 11 to front portion with hand, see Fig. 4, make upper handle 1 and lower handle 3 remove lockup state, the back backstay 12 of uncapping has broken away from prominent 32, under the effect of backstay spring 15, descend, making that prominent 112 at the rear portion broken away from column 121 holes is blocked by the head of column 121 can't be backward, and apron pushes away the hole that the extension body 131 of post 13 inserts on the backstay columns 121, sees Fig. 3, and the head that has kept push button 11 is only being started 21 top, only start and to rise thereby make, play and do not close lid and put security protection effect that can not upward pressure in the pot in place.The cap-rotating type safety of the utility model and prior art is ended the problem that the opening mechanism difference is not exist maloperation, just when backstay 12 is pressed under unexpected situation, because the extension body 131 that apron pushes away post 13 has blocked backstay 12 and has moved upward, thereby can not make 21 rises of only starting yet, be upper and lower handle do not close the lid put in place, pot inner pressure can not rise yet, thereby thoroughly eliminates the potential safety hazard that the cap-rotating type safety of prior art is ended opening mechanism.
