Abstract
An electric pressure cooker capable of realizing directional pressure relief comprises a cooker cover, a cooker lining, a cooker body and a pressure relief valve, wherein the cooker cover comprises a surface cover, an inner cover, a cover board and a sealing ring arranged on the cover board; a fixing groove with a lower opening is formed in the circumferential edge of the cover board; the sealing ring comprises a base and a sealing part with an arc-shaped cross section; the base is embedded in the fixing groove; a ring-shaped buckling edge is arranged at the lower part of the radial inner side of the base; the arc-shaped sealing part is matched with the upper opening of the cooker lining. The electric pressure cooker is characterized in that a clamping groove is formed in the outer ring-shaped wall board of the fixing groove; a clamping tongue is arranged on the outer circumferential wall of the base; a pressure relief notch is formed in the axial end surface of the axial part of the sealing part; the ring-shaped buckling edge is bulked with the circumferential edge of the lower surface of a pressure disc, and the clamping tongue is in embedded connection with the clamping groove. Through the adoption of the structure, when the pressure relief valve is blocked or damaged, the sealing ring at the pressure relief notch is separated from the cooking lining to realize pressure relief under the action of cooker lining gas pressure, as a result, the purpose of preventing cooker explosion is realized.
Description
Technical field
The utility model relates to a kind of electric pressure pot.
Background technology
Currently available technology, a kind of electric pressure pot, comprise pot lid, pot courage, pot body and relief valve, pot lid comprises cover, inner cap, cover plate and setting sealing ring on the cover board; Inner cap and middle cover pivot joint, sealing ring coordinates with the upper shed of pot courage; The upstream end of relief valve stretches out and is connected with the pot gallbladder intracavity through cover plate; The circumferential edge of described cover plate has the holddown groove of under shed, described sealing ring comprises the curved sealing of pedestal and cross section, pedestal embeds in holddown groove, and the ring buckle limit is arranged at the radially inner side bottom of described pedestal, and described curved sealing coordinates with the upper shed of pot courage.The problem existed is: in the situation that relief valve stops up and damages, normally pressure release, cause quick-fried pot, has potential safety hazard.
Summary of the invention
The purpose of this utility model is: a kind of electric pressure pot of directional pressure venting is provided, and it can be in the situation that relief valve be ineffective, and effectively pressure release prevents quick-fried pot.
The utility model is achieved in that a kind of electric pressure pot of directional pressure venting, comprises pot lid, pot courage, pot body and relief valve, and pot lid comprises cover, inner cap, cover plate and setting sealing ring on the cover board; Inner cap and middle cover pivot joint, sealing ring coordinates with the upper shed of pot courage; The upstream end of relief valve stretches out and is connected with the pot gallbladder intracavity through cover plate; The circumferential edge of described cover plate has the holddown groove of under shed, described sealing ring comprises the curved sealing of pedestal and cross section, pedestal embeds in holddown groove, and the ring buckle limit is arranged at the radially inner side bottom of described pedestal, and described curved sealing coordinates with the upper shed of pot courage; Its special character is: on the outer shroud wallboard of described holddown groove, a draw-in groove is arranged; Pedestal is outer circumferentially has a block tongue on wall;
The pressure release breach is arranged on the axial end of the axial part of described sealing;
The circumferential edge of the lower surface of ring buckle limit and described platen fastens, and block tongue and draw-in groove are chimeric.
A kind of electric pressure pot of directional pressure venting, its special character is: described block tongue is adjacent with the pressure release breach.
The electric pressure pot of a kind of directional pressure venting of the utility model, owing to adopting such structure, in the situation that relief valve stops up or damages, due to the effect of pot courage body pressure, the sealing ring of pressure release indentation, there separates and pressure release with the pot courage, thereby has reached the purpose that prevents quick-fried pot.
The accompanying drawing explanation
Fig. 1 is the uncap stereogram of state state of the utility model.
Fig. 2 is the three-dimensional exploded view of the utility model pot lid.
Fig. 3 is the three-dimensional cutaway view of the utility model platen and sealing ring assembled state.
Fig. 4 is the three-dimensional exploded view of the utility model platen and sealing ring assembled state.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of electric pressure pot of directional pressure venting, comprising that pot cover 1, pot courage 2, pot body 3 and relief valve 4, and pot covers 1 and comprises cover 11, inner cap 12, cover plate 13 and setting sealing ring 14 on the cover board; Middle cover 31 pivot joints of inner cap 12 and pot courage 3, sealing ring 14 coordinates with the upper shed of pot courage 2; The upstream end of relief valve 4 through platen 13 stretch out and with pot courage 2 intracavity inter-connections; The circumferential edge of described cover plate 13 has the holddown groove 131 of under shed, described sealing ring 14 comprises the curved sealing 142 of pedestal 141 and cross section, pedestal embeds in holddown groove 131, as shown in Figure 3, ring buckle limit 1411 is arranged at the radially inner side bottom of described pedestal 141, and described curved sealing 142 coordinates with the upper shed of pot courage 2; Sealing 142 is top laminating, the axial part 1422 and the 2 inwalls laminatings of pot courage of position 1421 and pot courage 2 radially.
One draw-in groove 132 is arranged on the outer shroud wallboard of described holddown groove 131; On the outer circumferential wall of pedestal 141, a block tongue 1412 is arranged;
On the axial end of the axial part 1422 of described sealing 142, pressure release breach 143 is arranged;
Described block tongue 1412 is adjacent with pressure release breach 143.
The utility model in use, in the situation that relief valve 4 stops up or damages, along with pot courage 2 internal pressures rise, when reaching the pressure of setting, due to the effect of pot courage 2 interior gas pressures, the sealing ring 14 at pressure release breach 143 places separates with pot courage 4, pressure is through the 143 places pressure release of pressure release breach, thereby reach directional pressure venting, and prevent from quick-fried pot from eliminating safe hidden trouble.
Above-described is only preferential embodiment of the present utility model.It should be pointed out that for the person of ordinary skill of the art, in the situation that do not break away from the utility model principle, can also make some improvement and modification, this also is considered as protection domain of the present utility model.
