The utility model content:

The purpose of this utility model is to provide a kind of instructions for use of satisfying the conjuncted electric pressure cooking saucepan that pot cover is connected with the pot body, guarantees that when pressure cooker lid was not built, pot inner pressure can not raise, when in the pot pressure being arranged, and the electric pressure cooking saucepan pot cover that pot cover can not be opened.The utility model is reasonable in design, use is reliable.

The technical solution of the utility model is: comprise and the hinged inner cap of pot body, covering in being installed in can be around the inner pot cover of its center rotation, the mount pad that is connected with inner pot cover, inner pot cover is provided with float-controlled valve, wherein also be provided with sliding bar on the inner pot cover, one end of sliding bar is arranged in the slideway between mount pad and the inner pot cover, cover in the other end places set, can do within it in the guide groove of radial displacement, and sliding bar is provided with at inner pot cover and pot body and fastens when putting in place through hole over against float-controlled valve.

One end of above-mentioned sliding bar is provided with the reference column of projection, and sliding bar is fixed on inner cap by the reference column activity radially to be had in the guide groove of displacement difference.

Above-mentioned slideway is made on the mount pad, or slideway is made on the inner pot cover, or mount pad and inner pot cover surround slideway.

Above-mentioned mount pad is provided with the limited post of projection, and limited post is movably placed in the set gathering sill of inner cap.

The utility model is owing to adopt by the cooperating of float-controlled valve and sliding bar, and when pot cover and a pot body did not close fully, sliding bar can effectively stop the spool of float-controlled valve to rise, and makes pot to be in exhaust condition, and pot inner pressure can not rise.In normal operation, the spool of float-controlled valve is placed by pot inner vapor pressure jack-up and plays self-locking action by the hole on the sliding bar, can not uncap.When the whole dischargings of steam in the pot finished, the spool of float-controlled valve was because deadweight is fallen, and normally folding of pot cover guarantees that the user is safe in utilization.The utility model is a kind of reasonable in design, simple in structure, and stable performance is safe in utilization, convenient and practical electric pressure cooking saucepan pot cover.

The specific embodiment:

Embodiment:

Structural representation of the present utility model as shown in Figure 1, 2, 3, comprise and the hinged inner cap 1 of pot body, being installed in can be around the inner pot cover 2 of its center rotation on the inner cap 1, the mount pad 3 that is connected with inner pot cover 2, inner pot cover 2 is provided with float-controlled valve 5, wherein also be provided with sliding bar 4 on the inner pot cover 2, one end of sliding bar 4 is arranged in the slideway 3A between mount pad 3 and the inner pot cover 2, the other end places on the inner cap 1 in the guide groove 1A set, that can do radial displacement within it, and sliding bar 4 is provided with at inner pot cover 2 and pot body and fastens when putting in place through hole 41 over against float-controlled valve 5.Above-mentioned slideway 3A is made on the mount pad 3, or slideway 3A is made on the inner pot cover 2, or mount pad 3 surrounds slideway 3A with inner pot cover 2.

For the slip of guaranteeing sliding bar 4 freely, an end of above-mentioned sliding bar 4 is provided with the reference column 42 of projection, sliding bar 4 is fixed on inner cap 1 by reference column 42 activities radially to be had in the guide groove 1A of displacement difference.

Fasten to bit position for effectively determining whether pot cover is in a pot body, above-mentioned mount pad 3 is provided with the limited post 3B of projection, and limited post 3B is movably placed in the set gathering sill 1B of inner cap 1.

Operation principle of the present utility model is as follows: when rotation mount pad 3, the limited post 3B of mount pad 3 slides in inner cap 1 set gathering sill 1B, simultaneously, inner pot cover 2 drives sliding bar 4 and radially slides in the guide groove 1A of inner cap 1, when limited post 3B arrives the end of inner cap 1 set gathering sill 1B, this position is the position that pot cover and pot body are uncapped, the sliding position of sliding bar 4 such as Fig. 6 during this position, shown in 7, through hole 41 staggers mutually with float-controlled valve 5, the spool of float-controlled valve 5 is stopped by sliding bar 4 can not be to top offset, can not form sealing state in the pot, the user is as the beginning cooking food, then pot inner pressure can not rise, thereby avoids pressure cooker " quick-fried pot " phenomenon to occur, guarantees that the user is safe in utilization.

When rotation mount pad 3, when making limited post 3B arrive the other end of inner cap 1 set gathering sill 1B, this position is that pot cover fastens to bit position with the pot body, and the sliding position of sliding bar is shown in Fig. 4,5 during this position, through hole 41 is over against float-controlled valve 5, at this moment, the user can begin heat food, can form operating pressure in the pot after the heat food, the spool of float-controlled valve 5 can be by pot inner vapor pressure jack-up, form sealing state in the pot, and can not uncap by 41 self-locking actions of through hole on the sliding bar 4.

After food is cooked, treat that pot interior steam all discharges when finishing, the spool of float-controlled valve 5 is owing to deadweight is fallen, and normally folding of pot cover guarantees that the user is safe in utilization.The utility model is a kind of reasonable in design, simple in structure, and stable performance is safe in utilization, convenient and practical electric pressure cooking saucepan pot cover.
