The structure of container body and element board

In each embodiment as described below of the present utility model, be provided with the heating element plate 12 of the part or all of base plate of the liquid-storage container that forms heating vessel or heating chamber 5.The sidepiece of liquid-storage container 5 is formed by the container wall of container body 1, and container wall can be made by for example plastics, metal, glass or stupalith.

In preferred embodiment of the present utility model, the cross section of container wall is circular about the horizontal plane in the zone of element board 12, and element board 12 roughly is circular; In other embodiments, can use such as oval-shaped other shape.

The diameter of container can reduce with height, so that element board 12 must be inserted in the under shed of container; Alternatively, container can have parallel sidepiece or diameter can increase with height, and in this case, element board 12 can be inserted through the upper shed of container.Element board 12 can directly seal against container wall, or can be provided with the ring-type mating part between element board 12 and container wall.Element board 12 can be assemblied in the container wall, or extends beyond container wall and seal against the outer surface of described container wall.

Element board 12 has the Rotational Symmetry section around its central axis, and this Rotational Symmetry section is perpendicular in use.Element board 12 comprises the basically smooth part that is positioned at the center and from the downward horizontal expansion of described core and be arranged essentially parallel to the channel portion 12a of container wall.The end portion of flange 12a can extend to form the lip shape 12b of section by outward radial.

Element board 12 is metals, and preferably such as stainless steel.The described basically smooth part that is positioned at the center can comprise one or more steps that along the circumferential direction extend, for example in order to larger intensity to be provided or to adapt to specific heating equipment.

The annular seal 400 of being made by elaxtic seal is positioned at around the flange 12a.Sealing 400 comprises groove and supporting walls 406, and the lip shape 12b of section is assemblied in the described groove, and supporting walls 406 extends radially inwardly below the lip shape 12b of section, therefore Sealing 400 is fixed on the flange 12a.Sealing 400 comprises and radially extends to get in the more circumference fin-shaped section 23 one, the circumferential seal between this fin-shaped section forming element plate 12 and the container body 1.

In specific embodiment of the utility model, heating element includes the heating element 39 of sheath, this has the heating element of sheath and element board 12 to pass through diffuser 410 thermo-contacts, yet, component type is unrestricted, and embodiment of the present utility model also is fit to use for example die casting and/or thick film element plate, and wherein heating element is arranged on the dielectric layer on the downside that is formed on element board 12 as one or more thick-film heating tracks (track).

A kind of in order to there is no that the mode of further improving the integrity of Easifix type seal in the situation that increases cost of material is that one or more sealing surfaces at Sealing provide additional circumference flank, for example on the internal diameter of Sealing and/or the circumference fin-shaped section of Sealing additional circumference flank is provided.According to described seal configuration, additional circumference flank can provide some or all in the following advantage.

1) in the circumference flank is not arranged on structure on the sealing surfaces of circumference radiating fin, with the surface opposite across smooth Sealing, in assembly process, can be conducted through the circumference flank across Sealing by any active force that fin-shaped section produces, therefore the local sealing load that has increased in the flank zone.

2) in the circumference flank was not arranged on structure on the sealing surfaces of circumference fin-shaped section, the circumference flank increased the part tightness or the sealing of the Sealing in the flank zone.For example, in the situation of the element board of 140mm, it is about 1.5% that the 1mm flank will make the stretching in the flank zone increase, and 3 millimeters flanks will make the stretching in the flank zone increase about 4.5%.

3) increase of less flank can make Sealing in the surface of element board and/or container body on any defective more tolerate.

4) increase of less flank can be used for preventing or limiting capillarity.

In each embodiment as described below of the present utility model, one or more flanks that circumferentially extend 27 can be formed at least a portion of sealing surfaces of Sealing 400, and described sealing surfaces is Sealing 400 and the part that for example contacts for one or more parts sealings of container wall and/or element board 12 heating vessel.Although can utilize overlapping circumferential section or other variation to realize similar effect, (one or more) flank 27 preferably extends around Sealing 400 along the circumference Perfect Ring, in order to reliable sealing effect is provided.

(one or more) flank 27 can be formed in sidewall 450, (one or more) fin-shaped section 23 and/or on another part of the formation sealing surfaces of Sealing 400.(one or more) flank 27 is preferably roughly less than (one or more) fin-shaped section 23, and outstanding with smaller szie from the sealing surfaces of Sealing 400.In one example, the cross sectional area of fin-shaped section 23 is about 5mm ²And the cross sectional area of flank 27 is about 0.06mm ²Usually, the cross sectional area of flank 27 can be less 10 times to 100 times than the cross sectional area of fin-shaped section 23.Size between fin-shaped section 23 and the flank 27 is compared to different application and can changes so that flank 27 can the compensation vessel wall and element board 12 between different manufacturing tolerancess.The cross-sectional profiles of flank 27 can be for example sub-circular, semicircle or triangle; Yet this shape is unrestricted, and any other suitable form or shape can fall within the scope of the present utility model.

Preferably, Sealing 400 is for example formed by the material of homogeneity basically by mold treatment.Alternatively, flank 27 can form and in the mold treatment process of for example using ' two shot-peenings (twin-shot) ' processing or be fixed to Sealing 400 after the mold treatment by processing separately.Flank 27 can be formed by the material different from the remaining part of Sealing 400; Then flank 27 can have different hardness.Alternatively or in addition, the surface of Sealing 400 can be processed in order to change the characteristic of flank 27, for example, makes described flank sclerosis or softening by for example vulcanizing treatment.
