Description

Technical Field

[0001] The utility model relates to a multifunctional double-layer kettle which is easy to process and belongs to the technical field of kettles. Background Art

[0002] At present, the kettle body in the prior art is generally a single-layer stainless steel kettle body welded with a spout, and the single-layer kettle body has poor thermal insulation effect. In order to improve the thermal insulation effect, the kettle body needs to be designed as a double-layer kettle body or a double-layer vacuum kettle body, and the connection problem between the spout and the double-layer kettle body needs to be solved.

[0003] At present, CN211657985U discloses a stainless steel double-layer vacuum kettle with a long spout and water outlet from the lower part of the kettle body, including a kettle body and a long spout. The kettle body includes an outer liner, an inner liner and a water outlet steel pipe. The side wall of the outer liner and the side wall of the inner liner are respectively provided with a mounting hole. The two ends of the water outlet steel pipe are respectively aligned with the two mounting holes and welded and sealed. A vacuum chamber is formed between the outer liner and the inner liner. The connecting end of the long spout is sealed and connected to the water outlet steel pipe. The beneficial effects of the utility model are: the structure is simple, and the outer liner and the inner liner are formed into a vacuum chamber by first connecting the water outlet steel pipe to the outer liner and the inner liner, and then riveting the long spout. In this way, the beverage stored in the vacuum kettle body can be kept warm for a longer time, which improves the consumer experience. In the reproduction process of this structure, the outer liner mounting hole also needs to be aligned with the water outlet steel pipe and then welded, which is inefficient. Utility Model Content

[0008] The pot bottom is also included, wherein the outer side of the pot bottom is connected to the lower end of the outer liner by welding, and the inner side of the pot bottom is connected to the bottom of the inner liner by welding.

[0009] The inner side of the pot bottom is provided with a flange, and the flange is welded to the inner pot bottom. A large gap is left before the pot bottom, which is convenient for connecting objects such as a heating plug.

[0010] The upper end of the inner liner is provided with an inner opening ring, the upper end of the outer liner is provided with an outer opening ring, and the inner opening ring and the outer opening ring are welded and connected, so that the welding effect and the sealing effect are better.

[0011] The outer liner is provided with a positioning column, and the positioning column is connected to a handle through a connecting rod.

[0012] The inner mouth ring and the outer mouth ring are provided with a pot cover.

[0013] The bottom of the kettle is also provided with a composite bottom sheet. The inner liner is titanium, and the composite bottom sheet is aluminum, which can boil water faster (titanium + aluminum sheet + brazing), and aluminum has better thermal conductivity.

[0014] The inner liner and the outer liner are in the shape of a cup, a bottle or a pot.

[0015] The utility model has the following advantages and beneficial effects:

[0016] The utility model relates to a multifunctional double-layer kettle which is easy to process. The inner liner, the spout, the outer liner and the bottom of the kettle can all be formed separately. The inner liner and the outer liner are first welded into shape, and then the holes of the inner liner and the outer liner are cut by laser. After cutting, the adapters of the inner liner and the outer liner are welded, and then vacuum is drawn. The whole process is simpler than the existing process. The circular ring piece in the adapter and the vertical piece are welded to connect the inner liner and the outer liner respectively. The air tightness is high, the combination is firm and strong, the process is simple, and the cost performance is better. The higher the yield rate of the adapter, the higher the yield rate of the product. No punching machine is needed, the safety factor is higher, the yield rate is higher, and the cost is saved.
