Detailed Description

The invention is further illustrated with reference to the following figures and examples.

As shown in figure 1, the invention provides a glass electric kettle which at least comprises a base 4, a kettle body fixed on the base 4 and a heating device arranged in the base 4. This kettle body includes glass inner bag 1, locate the shell 2 of 1 lateral surfaces of glass inner bag and locate glass inner bag 1 and go up terminal hu zui subassembly 3, by hu zui subassembly 3 with glass

inner bag

1 and 2 both go up terminal stationary phase even, thereby keep away the space and contactless formation insulating layer between glass inner bag 1 and the shell 2.

The glass liner 1 comprises a glass cavity and a heating seat, and the glass cavity is embedded in the heating seat. The heating seat of the glass liner 1 is positioned above the heating device, and the heat generated by the heating device during working is conducted to the liquid in the glass cavity through the heating seat, so that the heating function is realized.

The kettle body is arranged into a double-layer structure, and the shell 2 has at least three functions: firstly, the shell 2 can protect the glass inner container 1 and reduce the probability of damage of the glass inner container 1, thereby improving the durability and prolonging the service life of the glass electric kettle; the housing 2 can be made of plastic, metal and other materials, and the appearance of the glass electric kettle can be improved through the shape, surface color or/and surface pattern and the like on the housing 2, so as to meet the requirements of users; thirdly, the heat insulating layer between the glass inner container 1 and the shell 2 can prevent the heat of the heating liquid in the glass inner container 1 from being conducted to the shell 2, prevent the shell 2 from scalding hands in the using process, also can reduce the heat dissipation of the glass inner container 1 to a certain extent, and has better heat insulation effect compared with the electric kettle with a single-layer kettle body structure.

Referring to fig. 2 and 3, the spout assembly 3 includes a spout portion 31 and a limit coupling ring 32 connected to a lower end of the spout portion 31. The spout portion 31 has a larger-sized water inlet 311 at an upper end thereof, and a water outlet 312 at a side of the spout portion 31 for pouring hot water from the glass liner 1. The section of the limit connecting ring 32 is in a shape of 'Jiong', a first annular groove 33 for accommodating the upper end of the glass liner 1 is arranged between the outer side edge and the inner side edge of the limit connecting ring 32, and the notch of the first annular groove 33 is arranged downwards. The upper end part of the outer side edge of the limiting connecting ring 32 is provided with a connecting end part 311 matched with the inner side surface of the spout part 31, and the limiting connecting ring 32 is hermetically connected with the inner side surface of the spout part 31 by welding, bonding, pressing and the like by utilizing the connecting end part 311 (for example, the inner side surface of the spout part 31 is in a concave arc shape, and the outer surface of the connecting end part 311 is in a convex arc shape matched with the inner surface of the spout part 31 and with the same radian); and, the lower end of the outer side of the limit connecting ring 32 is bent, so that a second annular groove 34 for accommodating the upper end of the outer shell 2 is formed between the lower end of the outer side of the limit connecting ring 32 and the inner side of the spout 31, and the notch of the second annular groove 34 is arranged downward.

As further shown in conjunction with fig. 1, 4 and 5A. The upper end of 2 lateral surfaces of shell, lower end all are equipped with step portion, and the lower end of shell 2 links to each other with the upper end lock of 4 medial surfaces of base, and the step portion of 2 lower ends of shell withstands the upper end of base 4 to reduce the seam and make both appearances more smooth between base 4 and the shell 2. At this time, the upper end of the glass liner 1 is inserted into the first annular groove 33 of the limit connecting ring 32, the upper end of the glass liner 1 is fixed in the first annular groove 33 by an adhesive (such as resin), the upper end of the outer shell 2 is inserted into the second annular groove 34, the step part of the upper end of the outer shell 2 is pressed against the lower end of the spout part 31, the seam between the outer shell 2 and the spout part 31 is small, and the outer shapes of the outer shell 2 and the spout part 31 are smooth. Thus, the glass inner container 1, the outer shell 2, the spout assembly 3 and the base 1 are assembled into a whole to form the glass electric kettle.

As further shown in conjunction with fig. 1, 4 and 5B. In one embodiment, the glass electric kettle is added with a light display effect corresponding to the working state, and particularly, the glass electric kettle further comprises: a lamp ring 5 for providing light display, an elastic support 6 fixed on the base 4, wherein the elastic support 6 is positioned below the lamp ring 5 and presses the lamp ring 5 on the outer bottom surface of the glass liner 1.

Because the glass liner 1 is inevitably subjected to the condition of large tolerance in the manufacturing process, in order to solve the problem that the display effect of the lamp ring 5 is influenced because the lamp ring 5 is deformed due to the large tolerance of the outer bottom surface of the glass liner 1 when the lamp ring 5 is arranged on the outer bottom surface of the glass liner 1, the lamp ring 5 can be tightly attached to the outer bottom surface of the glass liner 1 by adopting the elastic support 6, and the lamp ring 5 is prevented from being deformed in the assembling process. Specifically, the elastic support 6 includes: annular body 60, a plurality of connecting portion 61 (for example 61 be the double-screw bolt) that is used for with base 4 fixed linking to each other, a plurality of from annular body 60 last end level inwards extend the elastic support piece that sets up, have the lug 62 that upwards protruding was established on every elastic support piece, and the lateral surface of annular body 60 has a plurality of stopper 63 that extend the setting outwards, and the terminal conflict of this stopper 63 is at the medial surface of shell 2.

The elastic support 6 is fixedly connected with the base 4 through a connecting part 61. At the in-process of assembly kettle body, elastic support 6 is located the downside of lamp ring 5, forces from a plurality of different positions through lug 62 on a plurality of elastic support piece to put lamp ring 5 inseparable pressure in glass inner bag 1 outer bottom surface, avoided lamp ring 5 to produce in the assembling process and warp.

In addition, in order to further improve the reliability of the elastic support 6 and prevent the annular body 60 from deforming and losing the pressing function of the lamp ring 5, a plurality of support frames 41 are arranged in the base 4, when the elastic support 6 is fixed in the base 4, the lower end of the annular body 60 is pressed against the support frames 41, and the capability of the annular body 60 that is not deformed by stress is increased through the support frames 41.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
