The second embodiment
Fig. 6 is the profile of the utility model the second embodiment electric pressure cooking saucepan, the structure of Fig. 6 and the structural similarity of Fig. 1, therefore identical component symbol represents identical element, and the main difference point of the present embodiment and the first embodiment is for being provided with support protrusion between reinforcement and stay-warm case bottom.
Please merge referring to Fig. 6-Fig. 8, in the present embodiment, described stay-warm case 21 bottoms are provided with at least two strip support protrusion 22, support protrusion 22 is fixed on described stay-warm case 21 bottom surfaces, in the present embodiment, described support protrusion 22 is one-body molded with stay-warm case 21 bottoms, the strip convex tendon of support protrusion 22 for being parallel to each other, and the quantity of described support protrusion 22 is two, reinforcement 60 is arranged in support protrusion 22, reinforcement 60 is provided with through hole, and jockey 82 is fixed to reinforcement 60 on the second leg 412 through through hole.In general, because the rigidity of reinforcement 60 is larger, thereby the deflection of reinforcement 22 is smaller, when pressure forces reinforcement 60 deflections when larger, for example, while arriving certain threshold value, reinforcement 60 is just easy to fracture, in order to prevent the fracture of reinforcement 60, in the present embodiment, on reinforcement 60 for being fixed to through hole on the second leg 412 between two support protrusion 22, the through hole corresponding thereto distance of 22 of both sides adjacent supports projections is not more than 6mm, in the present embodiment, the distance that the through hole support protrusion adjacent with its left side is 22 is not more than 6mm, the distance of the support protrusion 22 that through hole is adjacent with its right is not more than 6mm, be reinforcement top the second leg 412 corresponding thereto the distance of 22 of adjacent support protrusion in both sides be not more than 6mm, the distance here refers to the distance L between the nearest limit of the center support protrusion 22 that both sides are close to corresponding thereto of through hole, the i.e. central point of the second leg 412 distance L between the nearest limit of the contiguous support protrusion 22 in both sides corresponding thereto, refer to Fig. 7.Because the distance of through hole and support protrusion 22 is smaller, thereby the pressure that the second leg 412 is applied on reinforcement 60 is mainly delivered in support protrusion 22, thereby reinforcement 60 is not easy fracture.In addition, in other embodiment of the present utility model, the quantity of described support protrusion can also be not limited to two, and those of ordinary skill in the art can increase according to actual conditions the number of support protrusion, for example, can also increase support protrusion in the periphery of the present embodiment two support protrusion.And, in other embodiment of the present utility model, described reinforcement through hole can also directly contact with support protrusion, the second leg be located immediately at support protrusion directly over, in such cases, the number of described support protrusion can also be one, and preferably, the area of described support protrusion wants design comparison large.
In addition, please continue referring to Fig. 7-Fig. 8, described reinforcement is provided with at least two positioning ports 61, corresponding, described support protrusion 22 is provided with keeper 62, and described positioning port 61 is two in the present embodiment, it is all through hole, described keeper 62 is a cylindrical bar, and described keeper 62 is one-body molded with described support protrusion 22, and described keeper 62 positions through 61 pairs of reinforcements 60 of described positioning port.
In the present embodiment, described support protrusion 22 is bar shaped convex tendon, but the utility model is not limited to this, in other embodiment of the present utility model, described support protrusion can also be circular convex tendon, reinforcement is arranged in support protrusion, on reinforcement, for the through hole being fixed on the second leg, be positioned at circular support protrusion, through hole is not more than 6mm with the distance of relative both sides adjacent supports projection, be reinforcement top the second leg corresponding thereto the distance between both sides adjacent supports projection be not more than 6mm, the distance here refers to that the distance of any point on through hole center and adjacent supports projection inner edge is not more than 6mm, described circular support protrusion can be continuous, also can be interrupted setting.
In above two embodiment, described reinforcement is square, but the utility model is not limited to this, and in other embodiment of the present utility model, described reinforcement can also be other known shapes such as circle.
In above two embodiment, described elastic component comprises the base of folded spring shape elastic plate and support elastic plate, but the utility model is not limited to this, and those of ordinary skill in the art also falls in scope of the present utility model the distortion of elastic component according to prior art.
In sum, in the utility model, owing to being respectively equipped with the reinforcement of elastic component and raising stay-warm case intensity between a plurality of legs and stay-warm case bottom, and under uniform pressure, the leg deflection of heat-generating disc connection elastic component is greater than the leg deflection of connection reinforcement part, because elastic component has larger elastic deformation, and the cost of reinforcement is lower, thereby structure of the present utility model has the large and advantage cheaply of the elasticity of taking into account.
The above; it is only the specific embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
