A kind of safe pressure cooker[technical field]
This utility model relates to a kind of pressure cooker, refers in particular to improve the pressure cooker of security performance.
[background technology]
Pressure cooker is culinary cuisine kitchen tools, and it, with unique High Temperature High Pressure function, substantially reduces the time cooked.In life, it is local that we it is frequently necessary to that the pressure cooker of the foods such as the most cooked rice, decoction carries another, as dining room is carried in kitchen, during carrying, if pressure cooker lid rotates under external force, that just very possible and pot body is outwarded winding split, and food boiling hot in so will result in pot spills, scald human body, human body is damaged.
In this utility model, we have proposed a kind of new technical scheme.
[utility model content]
The purpose of this utility model is to be to overcome the deficiencies in the prior art, it is provided that a kind of can ensure safety, and makes pot cover and the pot cannot the pressure cooker of split under non-released state.
In order to solve the technical problem of above-mentioned existence, this utility model employing following technical proposals:
This utility model is a kind of safe pressure cooker, includes a pot body, pot cover and inner bag, and along being provided with several indented ribs one in side with described pot, the indented ribs one being provided with several and pot body in described pot cover inner edge inlays the indented ribs two of rotation matching；Being additionally provided with on described pot cover after pot cover and pot body screw cannot the safety locking pin of split by both lockings.
In the improvement project to above-mentioned a kind of safe pressure cooker, described safety locking pin includes latch and is arranged on the nut of latch wherein end, one end；Described latch runs through the through hole of pot cover cover rim outside pot cover and extend into inside pot cover, and described nut is arranged on pot cover outside and can pull latch advance and retreat activity in through hole；Described latch is provided with and prevents latch to be withdrawn into the catch outside pot cover inside pot cover completely；The spring ordering about latch holding toward pot cover internal activity it is provided with between described catch and nut；Described latch withstand on after pot cover and pot body screw make on a corresponding indented ribs one pot cover and pot body cannot the derotation, and gradient R of this indented ribs one is 70 ° ~ 110 °.
In the improvement project to above-mentioned a kind of safe pressure cooker, described safety locking pin also includes bending safety plate, and the lower end of described bending safety plate is fixing with latch to be connected, and its upper end is provided with prohibits spacing ring within it by the float-controlled valve hoop on pot cover；Described spacing ring ensures to be stopped spacing when float-controlled valve is in pressure floating state by float-controlled valve and make latch exit the distance of indented ribs one scope completely less than latch toward the distance that exits outside pot cover.
In the improvement project to above-mentioned a kind of safe pressure cooker, described bending safety plate is structure as a whole with catch.
Compared with prior art, the beneficial effects of the utility model are: this utility model, by being provided with a safety locking pin at pot cover, needs to unlock safety locking pin, could be opened by pot cover；And when the pressure in pressure cooker is excessive, float-controlled valve not yet falls, safety locking pin cannot be unlocked, avoid that the pressure in pressure cooker is excessive opens the potential safety hazard that human body is caused by pot cover rashly, visible, this utility model is rational in infrastructure, pot cover cannot be opened under non-released state, ensured user's safety in use.
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings:

[detailed description of the invention]
This utility model is a kind of safe pressure cooker, as shown in Fig. 1,2,3,4,5, include pot body 10, pot cover 20 and inner bag, along being provided with several indented ribs 1 in above described pot body 10, it is provided with several indented ribs 1 with pot body 10 in described pot cover 20 inner edge and inlays the indented ribs 2 21 of rotation matching；Being additionally provided with on described pot cover 20 after pot cover 20 and pot body 10 screw cannot the safety locking pin 30 of split by both lockings.
Described safety locking pin 30 includes latch 31 and is arranged on the nut 32 of latch 31 wherein end, one end；It is internal that described latch 31 extend into pot cover 20 from the outside through hole running through pot cover 20 cover rim of pot cover 20, and described nut 32 is arranged on pot cover 20 outside and can pull latch 31 advance and retreat activity in through hole；Described latch 31 is provided with and prevents latch 31 to be withdrawn into the catch outside pot cover 20 inside pot cover 20 completely；It is provided with between described catch and nut 32 and orders about latch 31 and keep the spring 33 toward pot cover 20 internal activity；Described latch 31 withstand on after pot cover 20 and pot body 10 screw make on a corresponding indented ribs 11 1 pot cover 20 and pot body 10 cannot the derotation, and gradient R of this indented ribs 1 is 70 ° ~ 110 °.
Described safety locking pin 30 also includes bending safety plate 34, and the lower end of described bending safety plate 34 is fixing with latch 31 to be connected, and its upper end is provided with binds round the spacing ring 35 prohibited within it by the float-controlled valve 22 on pot cover 20；Described spacing ring 35 ensures to be stopped spacing when float-controlled valve 22 is in pressure floating state by float-controlled valve 22 and make latch 31 exit the distance of indented ribs 1 scope completely less than latch 31 toward the distance that exits outside pot cover 20.Described bending safety plate 34 is structure as a whole with catch.
This utility model is by being provided with a safety locking pin 30 at pot cover 20, so, pressure cooker is after pot cover 20 and pot body 10 screw, the latch 31 of safety locking pin 30 just withstands on indented ribs 1 so that pot cover 20 cannot be with pot body 10 derotation, and user needs to hold the nut 32 outside pot cover 20, latch 31 is exited toward pot cover 20 outside direction, make it cannot withstand on indented ribs 1, safety locking pin 30 is unlocked, so pot cover 20 could be opened；Secondly, owing to the spacing ring 35 on safety locking pin 30 is chain with float-controlled valve 22, when so making that the pressure in pressure cooker is excessive, float-controlled valve 22 not yet falls, even if holding the nut 32 outside pot cover 20, also safety locking pin 30 cannot be unlocked, avoid that the pressure in pressure cooker is excessive opens the potential safety hazard that human body is caused by pot cover 20 rashly, further increase its safing performance.
Although this utility model being described in detail with reference to above example, but be it will be apparent to one skilled in the art that by the disclosure, and in the case of the principle of the present utility model limited without departing from described claim and scope, this utility model can be made a variety of changes or revise.Therefore, the detailed description of disclosure embodiment is only used for explaining rather than for limiting this utility model, but is defined by the subject-matter of the claims the scope of protection.
