Because the inner container fastener 40 is connected with the bottom cover 30, the temperature controller 20 and the inner container 10 at the same time, the inner container fastener is required to be installed from the outer side of the bottom cover 30, so that the outer surface of the bottom cover 30 is used as a uniform reference, the tolerance zone in the assembling process is shortened, and the assembling effect is improved. It should be understood that the inner container fastener 40 is disposed to avoid the inner container limiting part 11, the first temperature controller limiting part 21, the second temperature controller limiting part 22 and the bottom cover limiting part 31 so as not to interfere with each other. As an example, the inner container fastener 40 is a screw, accordingly, as shown in fig. 4, an inner container screw post 12 and an inner container fastener screw post 32 are respectively provided on the inner container 10 and the bottom cover 30, and a through hole 23 is provided on the temperature controller 20, when assembling, the through hole 23 is sandwiched between the inner container screw post 12 and the inner container fastener screw post 32, the inner container fastener 40 is simultaneously passed through the inner container screw post 12, the through hole 23 and the inner container fastener screw post 32 and screwed, and the connection of the inner container 10, the temperature controller 20 and the bottom cover 30 is realized by the fastening force thereof.

In addition, as shown in fig. 4 and 5, the temperature controller 20 is also provided with a corresponding hole corresponding to the avoiding hole 33 of the bottom cover 30, and a plurality of openings are formed on the wall of the hole, which is a structure of the existing temperature controller 20' itself and can be directly used as a limiting female buckle, so that the existing temperature controller 20' can be directly utilized without improving the existing temperature controller 20', and the product optimization cost can be effectively reduced. As an example, since the existing thermostat 20' has three openings, this embodiment may provide three male limit fasteners spaced along the circumference of the avoiding hole 33 at corresponding positions of the bottom cover 30.

In some embodiments, optionally, as shown in fig. 11 and 12, the liquid heating vessel further comprises: the shell 60 is sleeved outside the inner container 10; and a housing fastener 70 for coupling the bottom cover 30 and the housing 60.

The liquid heating container of the embodiment of the present invention utilizes a small amount of inner container fasteners 40 to connect the inner container 10, the temperature controller 20 and the bottom cover 30, and there may be a case of insufficient extrusion to the casing 60. By further providing the case fastening member 70 to directly connect the bottom cover 30 and the case 60, reliable fixing of the case 60 can be secured. In addition, at this time, the case fastening member 70 also uses the outer surface of the bottom cover 30 as a reference, and the matching reference can be ensured to be uniform. It should be understood that the case fastening member 70 is disposed to avoid the inner container fastening member 40, the inner container limiting part 11, the first temperature controller limiting part 21, the second temperature controller limiting part 22 and the bottom cover limiting part 31 so as not to interfere with each other.
