Abstract

The utility model relates to a safety micro pressure cooking boiler, which is composed of a cooking boiler body, a cooking boiler bottom, and a cooking boiler cover. A pressure limitation valve and a valve core are arranged on the cooking boiler cover. A movable pressure buckle and a pressure cover ring are arranged on the cooking boiler body. The pressure cover ring is used for pressing the edge of the cooking boiler cover instead of the buckle type structure of the existing pressure cooker. The utility model has the advantages of the existing pressure cooker, fundamentally solves the problems of the safety hazard of the existing pressure cooker, and has the advantages of low cost, long service life, good insulation performance, and energy saving.

Description

Safe minute-pressure digester

The utility model belongs to a kind of kitchen cooker, and specifically, it is a kind of safety-type minute-pressure digester.

The culinary art pressure cooker is the widely used a kind of cooker of current family, and it is simple in structure, and the same food required time of boiling can shorten dramatically than the normal pressure pot, thereby has energy-conservation, the outstanding advantage in timesaving.Yet, its manufacture technology and material requirements, generally can not surpass 8 year from security consideration service life, and its pressure limiting spool and safe spool are easily blocked simultaneously, thereby explosion, dash security incident such as lid and happen occasionally, and have caused very big potential safety hazard to the user.

The purpose of this utility model is to provide a kind of safety-type minute-pressure digester, makes it both have an advantage of pressure cooker cooking food, can eradicate the deficiency of pressure cooker on safety again, simultaneously also low than the pressure cooker safe minute-pressure digester of its manufacturing cost.

Major technique measure of the present utility model is as follows:

A kind of safe minute-pressure digester mainly is made up of pot body, the bottom of a pan and pot cover, and body is affixed is integral with pot in the bottom of a pan, at pot handle is housed on one's body, and at the pot cover and the interface position of pot body sealing ring is housed, simultaneously:

1, be provided with a pressure limiting valve on pot cover, this pressure limiting valve is buckled on the spool;

2, flexibly connect clinching with connecting rod on the handle, and flexibly connect a gland ring in clinching, the free end of this gland ring can press on the edge of pot cover.

When needing cooking food, earlier thing to be cooked is put into pot, cover pot cover, up pull clinching, can up stretch toward gland ring, after the free end of gland ring rides over the edge of pot cover, down pull clinching again, the free end of gland ring is pressed on the edge of pot cover, under the normal condition, the pot inner vapor overflows from pressure limiting valve, in case because of certain reason (stopping up as pressure limiting valve) causes pot inner pressure to surpass setting, steam will promote pot cover toward rising, thereby make the flexible gland ring transformation of tool, between pot cover and pot body, form the space that steam flows, steam is overflowed from this space, reach the purpose that exhaust steam reduces pot inner pressure.After pot inner pressure reaches normal value, recover sealing state once again between pot cover and pot body.

Therefore, the utility model had both kept the advantage of existing pressure cooker cooking food, fundamentally solved its safety problem again, and because the raising of its security performance, it is minimized its manufacture technology and raw material requirement, reached the purpose that reduces production costs, also therefore prolonged its service life simultaneously.

Below in conjunction with accompanying drawing and the embodiment that provides thereof the utility model is further described:

Accompanying drawing is safe minute-pressure digester structural representation.

As shown in the figure, safety minute-pressure digester is made up of pot body, the bottom of a pan 16 and pot cover, and its bottom of a pan 16 is affixed in aggregates, as follows to each several part structure division below with the pot body:

1, pot cover: a pressure limiting valve 9 is housed on the pot cover, and this pressure limiting valve 9 is buckled on the spool 10, is provided with a filter mantle 14 in case spool 10 is blocked below spool 10; At the top of pot cover with holding screw 13 fixed installation one handles 1, establish in this handle 1 one can ccontaining pressure limiting valve 9 cavity; Junction with the pot body on pot cover embeds a sealing ring 4; For improving heat-insulating property, reach the purpose of further energy-saving heat preserving, its pot cover can be made the laminated heat-preserving structure, and promptly it is made up of lid skin 2, lid internal layer 18 and intermediate course 3, and interlayer 3 is vacuum layer or filled thermal insulation materials layer in the middle of it.

2, pot body: install handle 5 with holding screw 6 on one's body at pot, flexibly connect clinching 12 with connecting rod 17 on the handle 5, and activity connects the flexible gland ring 11 of tool in clinching 12, the free end of gland ring 11 can press on the edge of pot cover, for further improving its energy-saving heat preserving performance, the pot body is also made the laminated heat-preserving structure, and promptly it is made up of pot body skin 7, pot body internal layer 8 and intermediate course 15, and interlayer 15 is vacuum layer or filled thermal insulation materials layer in the middle of it.

The utility model is the advantage of the existing pressure cooker of tool both, has eradicated again Its potential safety hazard, and the energy-saving heat preserving performance is good, and manufacturing cost is more existing Low, the long service life of pressure cooker is arranged.
