Abstract
The utility model relates to a safety device matched with the existing pressure cooker and is connected with the lower part of an exhaust pipe in a pressure cooker cover. The utility model has the advantages of reasonable design, security, simple structure, strong practicability, convenient operation, easy cleaning and convenient assembly and disassembly. The safety device for pressure cooker can completely avoid that an exhaust vent is plugged by food during cooking. The utility model can be matched with the existing pressure cookers without changing the structure, and the kinds of cooking food such as rice water, kelp, etc. are not limited.
Description
The utility model relates to a kind of pressure cooker cover inside exhaust pipe lower end safety device.
In existing technology, pressure cooker cover inside exhaust pipe lower end is to connect with a hexagon internal threaded nut that is drilled with 7 holes.When cooking food, be easy to take place food and stop up the aperture accident that meets accident.Cook congee, the group food of sea-tangle is unsuitable working pressure pot, in case use, it is careful also to need.
The utility model purpose is to avoid above-mentioned weak point of the prior art and carries, and uses a kind of safety guard very easily, and safety can be avoided cooking congee, the group food of sea-tangle stops up chance.It mainly is to increase circulation area that the structure of hollow cap 1 forms the cone space, avoids pastel and large tracts of land food that whole passage is stopped up, even the large tracts of land blocking also can guarantee other hole normal exhaust of whole cone, it is perfectly safe to accomplish.
The purpose of this utility model can reach by following technical solution: the safety device of this pressure cooker is connected in pressure cooker cover inside exhaust pipe lower end, it is characterized in that it comprises the hollow cap 1 that is surrounded by wire netting.
The purpose of this utility model can also be expressed by following other measure: its hollow cap 1 comprises nut 2, and the metal liner bowl 3 and the thin metal otter board 4 of several holes arranged above.Nut 2 and metal liner bowl 3 adopt cold stamping shaped; Thin metal otter board 4 bound edges are in metal liner bowl 3, and it is shaped as cone.
The utility model compared with prior art has obvious advantage:
1) can replace existing hexagonal (hexagon)nut, and safe and reliable.
2) easy to use, practical, be easy to clean, mounting or dismounting are convenient.
3) cooking food is unrestricted.
4) do not change existing pressure cooker structure, all can supporting use.
Fig. 1 is that pressure cooker safety device master looks schematic diagram;
Fig. 2 is a pressure cooker safety device schematic top plan view;
The utility model is further described below in conjunction with accompanying drawing:
The nut 2 of Fig. 1, Fig. 2 and metal liner bowl 3 adopt the cold punching consolidation; Be shaped as cone, uniform boring on it.Nut 2 is a securing member, connects in pot cover inside exhaust pipe lower end.Approach metal otter board 4 bound edges on metal liner bowl 3, uniform boring on it.This device is designed to cone from overall structure, and is rationally distributed, is preferred plan.But do not get rid of other version, as Cylinder, triangle body, square body, gengon yet.This device and existing pressure cooker are supporting, only need former hex nut is pulled down, and change and can use.
