Description

A kind of electric kettle with hard kettle body

Technical field

The utility model relates to a kind of electric kettle, particularly a kind of electric kettle with hard kettle body.

Technical background

The electric kettle that uses hard materials such as glass, pottery to make the kettle bodies is used more and more, and the kettle body of hard is installed heat-generating disc in its bottom by dual mode, and first kind of mode is connected by silica adhesive between kettle body and heat-generating disc and seals; The second way be the kettle body with heat-generating disc between realize being connected, sealing by clamping elastic silica gel sealing ring.

First kind of mode is because the own precision of hard kettle body that glass, pottery etc. are made is lower, between the two gap is difficult to keep stable when boning with heat-generating disc, this just is easy to occur bonding slit, cause Hu Tiloushui, when the kettle body that leaks is repaired, the colloid that has adhered to is difficult to peel off, and causes scrapping of kettle body.

The shortcoming of the second way is that the sealing between kettle body and the heat-generating disc only depends on the sidewall of heat-generating disc and kettle body inwall that the extruding of sealing ring is finished, this extruding force also will guarantee can be in place smoothly when heat-generating disc is packed the kettle body into, in the precision of kettle body own just under the lower situation, the extruding force that sealing ring is subjected to is less, the reliability of sealing is lower, occur under the aging conditions after particularly using certain hour, the reliability of sealing is lower; Higher to the precision of kettle body in addition, the production cost of kettle body increases.

The utility model content

The utility model is in order to overcome defective in the above-mentioned prior art, by in sealing ring, setting a kind of rubber-like hard skeleton, and the fastening squeezing action by bolt, realize that hard kettle body is connected the fault-free life-span of increase electric kettle with long-time positiver sealing between the heat-generating disc.

For achieving the above object, the utility model provides a kind of electric kettle with hard kettle body, includes: kettle body, heat-generating disc and bottom are provided with sealing ring between kettle body and the heat-generating disc; Wherein, heat-generating disc, its edge is provided with outside flange; The kettle body, its lower port that heat-generating disc is installed is provided with the neck of contraction, and the uncovered size of neck makes heat-generating disc can put into the kettle body earlier when assembling greater than the edge contour of heat-generating disc; Bottom is the thin walled shell that the upper end is opened wide, and with the socket of kettle body lower port, the edge of thin walled shell is connected to the lower surface of kettle body, and heat-generating disc is fastenedly connected by the bottom of bolt and electric kettle; Sealing ring, its inner loop week is provided with groove, sets the rubber-like hard skeleton in the groove; Hard skeleton, the transverse width of its section can be connected on the athwartship plane of the flange bottom, edge of heat-generating disc and kettle body lower port neck.

In the technique scheme, hard skeleton has the vertical muscle that is connected with its horizontal section, and the length of vertical muscle extends to the narrowest place of kettle body lower port neck.

In the technique scheme, vertical muscle is arranged at the middle part of hard skeleton, forms the section structure of T shape, and vertical muscle is corresponding with the gap between heat-generating disc, the kettle body lower, neck end.

In the technique scheme, the outer joint angle between the athwartship plane of vertical muscle and hard skeleton arranges arc transition, and the cambered surface of the shape of circular arc and kettle body lower, neck end is suitable.

In the technique scheme, the lateral surface of sealing ring is fitted in the outer surface of hard skeleton and extends to the bottom of vertical muscle, makes the outer surface of sealing ring be subjected to butt, the extruding of kettle body lower port neck and hard skeleton, further improves sealing effectiveness.

In the technique scheme, the bearing surface of sealing ring and heat-generating disc, kettle body is provided with the sealing tooth of projection, and when the sealing ring butt, the extrusion of sealing tooth can be played better sealing effectiveness.

Compared with prior art, the utlity model has following beneficial effect:

1. by in sealing ring, setting the elasticity hard skeleton, and match with heat-generating disc flange, kettle body lower, neck end, under the bolted effect that connects bottom and heat-generating disc, sealing ring is pushed, positiver sealing effect when being implemented in assembling, simultaneously, in the work ageing process of sealing ring, can keep positiver sealing for a long time.

2. the assembling process between kettle body, heat-generating disc and the sealing ring is simple, the efficiency of assembling height.

3. the quality of fit between kettle body and the heat-generating disc requires to reduce, and improves the yield rate of kettle body, and the product cost that drives whole electric kettle reduces.
