Certainly, heat insulation loop 34 is also possible to be fixed on the side wall of insulation cover 12, and when dismantling insulation cover 12, heat insulation loop 34 can be with heat preservation Cover 12 is dismantled together, and certainly, heat insulation loop 34 can be separated with insulation cover 12, the two be made of different technique two match Part.
To sum up, the present embodiment has the advantages that
1, heat insulation loop is set below insulation cover 12, clamped using claw 51 heat insulation loop, insulation cover 12, liner flange and Inner cover, and the contact area of the claw 51 and heat insulation loop is less than the contact area of liner flange and insulation cover 12.Due to existing There is in technology the main pressure-bearing of bearing structure of " side stews " on liner flange, the strong of liner flange can be promoted by heat insulation loop Degree.Moreover, the contact area of insulation cover 12 and liner flange increases, so that liner flange is more uniformly stressed, reduce liner The intensity requirement of flange, to reduce the cost of liner.In the prior art, one is pot tooth, pot cover is arranged on liner flange The retainer of upper setting rotation is engaged pot tooth pressure-bearing, so that chucking power all concentrates in the pot tooth on liner flange, to pot tooth Intensity requirement is especially high, contacts since retainer is directly scraped with pot tooth lower surface, also high to the coating needs of pot tooth lower surface, makes It is at high cost at liner.In the prior art, also one is utilization clamps directly to clamp liner flange, and in the circumference of liner flange On, clamp is not capable of clamping whole circumference region, causes unbalance stress on liner flange, the chucking power that clamped region is subject to Greatly, the chucking power that other regions are subject to is small, and liner flange is caused to be easily deformed, so also high to the intensity requirement of liner flange. Likewise, contacted since clamp is directly scraped with liner flange lower surface, it is also high to the coating needs of liner flange lower surface, and The present embodiment can reduce the intensity requirement of liner by the way that heat insulation loop is arranged between claw 51 and liner flange, reduce liner The coating needs of flange lower surface greatly reduce the cost of liner.Generally speaking, due to being provided with heat insulation loop, so that this Embodiment can use the liner of " circle stews " cost, reach advantage possessed by " side stews ", for example setting handle, heating device are Electromagnetic wire coil etc..The cost of " side stews " liner is at 60 yuan or more in the prior art, and the cost of " circle stews " liner can accomplish 15 Member is hereinafter, and the present embodiment is further added by heat insulation loop and can reach can slightly thicken on the basis of existing " circle stew " liner The effect of " side stews ", within 30 yuan, opposite " side stews " liner cost significantly reduces cost.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to In this, being familiar with the those skilled in the art should be understood that the utility model includes but is not limited to attached drawing and specific embodiment party above Content described in formula.The modification of any function and structure principle without departing from the utility model is intended to be included in claims Range in.
