Specific embodiment

The utility model is described in detail below in conjunction with attached drawing.As shown in Figures 1 to 4.

Embodiment: referring to Fig. 1, a kind of Electric-heating Insulation Kettle comprising:

Vacuum kettle body, the vacuum kettle body include shell 3 and liner 2, and the upper end of liner 2 is connect with the upper end of shell 3, outside Gap 4 is equipped between shell 3 and liner 2；The bottom lower end surface of liner 2 is connected with intermediate plate 6, the outer end of intermediate plate 6 and liner 2 Bottom connection, and intermediate plate 6 be equipped with recessed mounting groove 7,7 inner heating device 5 of mounting groove；

Pedestal, pedestal are equipped with power connection mechanism 10 and chassis, and chassis includes side wall 11 and bottom plate 9, and power connection mechanism 10 is set to The upper end of bottom plate 9, side wall 11 is connect with the lower end of shell 3；

Intermediate bulkhead 8, between intermediate plate 6 and pedestal；The outer end of intermediate bulkhead 8 bends and connect with side wall 11；

Intermediate bulkhead 8 is equipped with upper recess 16, and the intermediate plate 6 is equipped with lower concave part 15, and upper recess 16 offsets with lower concave part 15 And upper recess 16, lower concave part 15 are equipped with string holes 19, power connection mechanism 10 passes through string holes 19 by conducting wire and is electrically connected with heating device 5 It connects；

Shell 3 and liner 2, intermediate plate 6 form external seal space, shape between liner 2 and intermediate plate 6 between intermediate bulkhead 8 At interior sealing space, external seal space, interior sealing space vacuumize to form vacuum space.

The heat preservation of electric kettle at present is generally kept the temperature using kettle body, and the heat preservation of kettle body mostly uses greatly thermal insulating material matter to be protected Temperature also has using vacuum heat-preserving, and vacuum heat-preserving is only the vacuum area that side is formed between shell and liner 2, and bottom of the pot is still So it is in radiating state；Although the heat dissipation of bottom of the pot is smaller, this heat insulation effect is poor, in the technical program, using bottle body vacuum The structure combined with bottom of the pot vacuum；Wherein bottle body vacuum passes through being vacuum formed between shell 3 and liner 2；Bottom of the pot vacuum includes Two parts: the 1, vacuum between 2 bottom of liner and intermediate plate 6；2, being vacuum formed between intermediate plate 6 and intermediate bulkhead 8；Wherein The vacuum space of second part is connected to bottle body vacuum space.Since bottom of the pot forms two parts vacuum space, can greatly subtract Few thermal loss, to improve heat insulation effect；The prior art can be used in 1 part of pot lid, the pot lid 1 being such as made into using heat-barrier material Deng.

Further, the upper end of the side wall 11 is equipped with outer annular groove, and the outer end of the intermediate bulkhead 8 bends downward shape At lower interconnecting piece 12, lower interconnecting piece 12 is located in outer arcuate slot and connect with side arm, the lower end of the shell 3 be placed on lower connection Portion 12 is outer and connect with lower interconnecting piece 12.

Preferably, the upper end lateral surface of the side wall 11 is equipped with the card hole of indent, and the lower interconnecting piece 12 is equipped with and card hole The card convex 20 matched, card convex 20 are connected in card hole.

For convenience of side wall 11 to be connect with intermediate bulkhead 8, the outer end of intermediate bulkhead 8 bends downward to form lower interconnecting piece 12,11 upper end of side wall is equipped with outer annular groove, and lower interconnecting piece 12 is placed in outer annular groove；In order to enable lower interconnecting piece 12 and side wall 11 It is completely embedded, the technical program is provided with card hole on side wall 11, and lower interconnecting piece 12 is provided with card convex 20.As equivalent variations, Interior annular groove also can be set in side wall 11, and the lower end of shell 3 is placed on interior annular groove；Certainly, the lower end of outer end and side wall 11 can also Card convex 20 and card hole is respectively set.The setting of card convex 20 and card hole facilitates pedestal that can be dismantled and be repaired, lower interconnecting piece 12 take the mode of welding to be attached in actual operation with the lower end of shell 3, so that inner space can seal.

Further, the inner fovea part 13 of upward indent is equipped in the middle part of the bottom surface of the liner 2.

After inner fovea part 13 is arranged, so that 2 bottom surface of liner has redundancy, in use, the bottom surface of liner 2 is heated Face, liner 2 can expand with heat and contract with cold；When expanding with heat and contract with cold, recess portion changes, and prevents from varying widely outside other portions, causes interior Gallbladder 2 deforms.

Preferably, the periphery of the intermediate plate 6 is equipped with connection ring 14, and the bottom of the liner 2 is equipped with and 14 phase of connection ring The loop concave of cooperation, connection ring 14 are fixedly connected on loop concave.

For convenience of the outer end of intermediate plate 6 to be connect with the bottom of liner 2, the technical program is used in the outer of intermediate plate 6 Setting connection ring 14 is enclosed, the bottom of liner 2 is equipped with loop concave, and connection ring 14 is located at loop concave and connect with liner 2, preferably Using welding manner, connection ring 14 is fixed on loop concave, naturally it is also possible to use other modes, such as bonding.Ring is set Shape concave surface also is located at the end of connection ring 14 in concave surface, when being sealed, can facilitate and be sealed end, while The lower end surface of the bottom surface and connection ring 14 that can make liner 2 maintains an equal level.In actual practice it is preferred to ground, the height of connection ring 14 Degree is greater than the middle part of intermediate plate 6, closer to avoid bottom surface of the middle part apart from liner 2 of intermediate plate 6, and influences heating device 5 installation.

Referring to fig. 4, further, the upper recess 16, one in lower concave part 15 be equipped with outer sleeve 18, another is equipped with Inner sleeve 17, inner sleeve 17 are located in outer sleeve 18, and the inside of inner sleeve 17 forms the string holes 19.

In the present embodiment, upper recess 16 is equipped with outer sleeve 18, lower concave part 15 is equipped with inner sleeve 17, inner sleeve 17, outer sleeve 18 can pass through punch forming；Secondly, setting outer sleeve 18, inner sleeve 17 make the connection between upper recess 16, lower concave part 15 Area increases, and improves sealing shape；Secondly, the inside area of inner sleeve 17 is far longer than intermediate plate 6, intermediate bulkhead 8 in string holes 19 The cross-sectional area at place so that when contacting with wire rod, sealing probability is can be improved in inner sleeve 17, while also facilitating installation to seal Part, such as sealing-plug, sealant.

Referring to Fig. 5, further, the upper end of shell 3 is equipped with spout 21, the lower end of spout 21 respectively with shell 3, liner 2 Welding.
