Description
Technical field
The utility model relates to pressure cooker, relates in particular to the self-locking structure of pressure cooker.
Background technology
The pressure cooker of prior art, seal to produce pressure by pot body pot cover, all with self-locking structure, its structure operated by rotary motion is on pot cover, realize by self-locking plate, self-locking plate spring, float-controlled valve, upper handle and lower handle etc., in use, can ensure the security of folding lid, prevent that pressure cooker from producing potential safety hazard in the time of misoperation.But along with social development, growth in the living standard, demand to new product is also more and more higher, for meeting market demands, develop a kind of pressure cooker of self-heating, at the inner pressure that produces of pot body, this self-heating pressure cooker is made up of inner pan body and outer pan body conventionally, heating bag is set between inner pan body and outer pan body, the space wrapping between inner pan body and outer pan body by heating produces heat and pressure, food in inner pan body is carried out to hot digestion, in order to ensure security performance, must between inner pan body and outer pan body, be equipped with a set of corresponding self-locking structure.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of self-locking structure of self-heating pressure cooker, can carry out self-locking to the inner pan body of self-heating pressure cooker and outer pan body, guarantees the security performance of pressure cooker.
The technical scheme that the utility model technical solution problem adopts is: the self-locking structure of self-heating pressure cooker, comprise pot cover, inner pan body and outer pan body, described inner pan body is provided with upper handle, described outer pan body is provided with lower handle, described inner pan body coordinates with described outer pan body clamping, between described inner pan body and described outer pan body, be provided with sealing ring, described upper handle is provided with self-locking plate, described self-locking plate is fixedly connected in described upper handle by self-locking plate spring, the upper end of described self-locking plate has push rod, the lower end of described self-locking plate has U-lag, the outside turnover in edge of described inner pan body then bends inwards, outwards this part edge of turnover forms the mounting groove of sealing ring, on the edge of described outside turnover, be provided with the perforate consistent with described push rod shape, described lower handle is provided with latching valve, described latching valve comprises valve seat, spool, valve body and Connection Block, described Connection Block is arranged on the pot wall of described outer pan body, described valve seat is arranged on described Connection Block, described valve body is arranged on described valve seat, described spool is arranged on also can be up and down in described valve body, described lower handle is also provided with the chute slidably reciprocating for described self-locking plate and the through hole passing for spool, described chute comprises flat segments and arc section, in the time that the lower end of described self-locking plate is positioned at the arc section of described chute, described spool can enter in the U-lag of described self-locking plate lower end.
Self-heating pressure cooker of the present utility model is (inner pan body and outer pan body do not coordinate and put in place) in the time there is no complete closing lid, upper lower handle does not overlap completely, the lower end of self-locking plate does not also enter the flat segments of chute, now, push rod stretches in the perforate on the outside edge turning down of inner pan body, withstands sealing ring, makes blow-by between inner pan body and outer pan body, pressure in pot can leak by the gap of sealing ring and tapping, and pot inner pressure can not continue to rise, interior outer pan body continues to relatively rotate, make lower handle further overlap (but not yet completely overlap), now the lower end of self-locking plate moves to the flat segments of chute, self-locking plate outwards shifts out under the effect of flat segments, the push rod of self-locking plate upper end is drawn out perforate, no longer withstand sealing ring, now sealing ring internally seals between outer pan body, between interior outer pan body, can produce pressure, but because upper lower handle does not overlap completely, self-locking plate lower end does not move to the arc section of chute, therefore spool can not enter in the U-lag of self-locking plate, but withstood by the lower end of self-locking plate, steam can be discharged between spool and valve body like this, pot inner pressure can not rise, thereby ensure the closing lid security of pressure cooker.
In the time that interior outer pan body cooperation puts in place, upper lower handle overlaps completely, the lower end of self-locking plate continues to move in the arc section of chute, now spool can enter in the U-lag of self-locking plate lower end, in the time producing pressure in pot, pot inner pressure by Connection Block, valve seat by spool jack-up to entering in U-lag, the position of upper lower handle is relatively fixing, be pressure cooker self-locking, interior outer pan body can not be opened, guarantee the security of uncapping.Complete when heating, when pot inner pressure declines, spool skids off U-lag under Action of Gravity Field, fall in valve body, now can rotate upper handle and open inner pan body, meanwhile, the self-locking plate of upper handle again enters in the perforate on inner pan body and withstands sealing ring under the effect of self-locking plate spring, for closing lid is next time prepared.
Adopting on the basis of technique scheme, the utility model is further technical scheme below can also adopting or combine and adopting:
Between the pot wall of described Connection Block and described outer pan body, by the sealing of O type circle, guarantee the pot wall sealing of outer pan body.
Between described Connection Block and valve seat, between valve seat and valve body and the surface that contacts with described valve body of spool is equipped with the O type circle for sealing, and guarantees the sealing in latching valve.
The beneficial effects of the utility model are: self-locking structure of the present utility model has adopted right-angle type self-locking structure between the upper lower handle of self-heating pressure cooker, solve practical operation problem, make structure more simple and convenient, install more rationally reliable, the security hidden trouble having existed while having ensured work, makes feel more relieved safe handling of pressure cooker; More safe and reliable in design, simple in structure, convenient cleaning.Between interior outer pan body, add water, need not generate heat bag time, this pan also can be used as general pressure cooker and on other burning things which may cause a fire disaster, heats use.
