Description
Technical field
The utility model relates to the electric pressure cooking saucepan product of kitchen appliance, is specifically related to a kind of pressure cooker sealing structure.
Background technology
The fixed form of the sealing ring of the electric pressure cooking appliance of existing market is: at stainless steel coil of interior welds of pot cover, in order to support sealing ring to guarantee the sealing of itself and interior pot, this kind structure exists following deficiency: solder joint affect outward appearance, cost is high and clean inconvenience.
In order to address this problem: publication number is to disclose two technical schemes in the patent of CN201481061: the first is: the side of pot cover increases projection, sealing ring is provided with annular groove, annular groove and pot cover projection pressure contact, this structure is used on the electric pressure cooking saucepan of elastic mechanism and (refers to that pot cover and outer pot fasten, interior pot is positioned on the heat-generating disc, sealing ring is sealed in when sealing between pot cover and the interior pot, and elastic mechanism is between heat-generating disc and outer pot) poorly sealed hidden danger arranged.Contact because sealing ring is rigidity with pot cover, when the pot inner pressure rising, sealing ring does not have enough displacement spaces.In order to ensure well sealing effectiveness, need to increase the height of pot cover, to guarantee sealing ring displacement space is arranged, but this will inevitably increase the cost of pot cover and sealing ring.The second is: the pot cover sidewall is provided with a step surface, and the pot cover projection is positioned under the step surface, and the annular convex shoulder of sealing ring embeds between the end face of pot cover projection and pot cover step surface.The projection of pot cover has affected the sealing between interior pot and the sealing ring in this structure, also has poorly sealed hidden danger.
The technical scheme of publication number CN201911870 is: the side at pot cover rushes groove, and the position corresponding at sealing ring increases projection, and back-off is arranged on the projection, utilizes the deformation of sealing ring, and back-off passes the groove of pot cover, forms interference fit, is assemblied on the product.The shortcoming of this scheme is: after pot cover rushed groove, the periphery of groove was sharper, and the user is when the dismounting sealing ring, and sealing ring is cut by the pot cover groove easily, forms easily poor sealing.
The utility model content
The purpose of this utility model is for overcoming the deficiencies in the prior art, a kind of pressure cooker sealing structure is provided, its good sealing effect, disassembly, cleaning convenience.
The purpose of this utility model is achieved in that a kind of pressure cooker sealing structure, comprise pot cover (1), cover (2) and sealing ring (3), cover (2) is positioned at the outside of pot cover (1), pot cover (1) is provided with through hole (4), sealing ring (3) is provided with projection (5), cover (2) is provided with buckle (6), it is characterized in that: described projection (5) is provided with groove (51), and the through hole (4) that the projection (5) on the described sealing ring (3) is passed on the pot cover (1) hangs on the buckle (6) by groove (51).
Projection (5) on the described sealing ring (3) is located at sealing ring (3) lateral wall or top radially, corresponding therewith, through hole (4) on the above-mentioned pot cover (1) is located at pot cover (1) sidewall or top, and above-mentioned buckle (6) is located at cover (2) madial wall or top radially.
In order to prevent that through hole (4) edge on the pot cover in the disassembly process (1) from scratching sealing ring (3), make installation more convenient, also be provided with the block reinforcement (8) corresponding with pot cover through hole (4) on the described cover (2), block reinforcement (8) is positioned at the both sides of pot cover through hole (4), and the width of through hole (4) is greater than the distance between the block reinforcement (8).
For avoiding buckle, block reinforcement on the cover to scratch sealing ring, buckle (6), block reinforcement (8) on the above-mentioned cover (2) are circumferentially with fillet.
For making sealing ring (3) more firm its self falling of avoiding is installed to get, and within the specific limits displacement of sealing ring (3), the A/F of described projection (5) upper groove (51) is less than the free-ended width of cover buckle (6), and the width in groove (51) groove is greater than the free-ended width of cover buckle (6).
Buckle (6) on projection (5) on the above-mentioned sealing ring (3), pot cover through hole (4), the cover (2) arranges respectively 3～6.
Described cover (2) is semi-surrounding or the full vinyl cover that surrounds.
The beneficial effects of the utility model are, by sealing ring being hung on the buckle on the cover, can effectively avoid sealing ring to come off, avoided simultaneously the edge of opening of pot cover to scratch sealing ring, sealing ring sealing effectiveness and service life have effectively been guaranteed, have simple in structure, cost is low, dependable performance, the advantage that makes things convenient for user's dismounting to clean.
