[0022] A heating tank structure of an electric thermos flask, referring to Figure 1 - Figure 2 , includes a barrel body 1, a barrel lid 2 and a sealing assembly. The barrel lid 2 and the barrel body 1 jointly enclose a receiving groove 3. An opening 4 is provided on the barrel body 1. The sealing assembly is a first adhesive layer and a second adhesive layer 5 spacedly arranged on the barrel lid 2. A convex portion 6 adapted to the opening 4 is provided on the barrel lid 2. The convex portion 6 is embedded in the opening 4. The first adhesive layer and the second adhesive layer 5 are used to connect the barrel lid 2 and the barrel body 1.

[0023] Further, the first adhesive layer includes a plurality of mounting platforms 7 provided on the barrel lid 2. An adhesive 71 is provided on the mounting platform 7. The barrel body 1 is connected to the barrel lid 2 through the adhesive 71.

[0024] Further, the first adhesive layer includes a plurality of mounting platforms 7 provided on the barrel lid 2. A sealing ring is provided in the mounting platform 7 and the upper end of the sealing ring extends out of the mounting platform 7. When the barrel lid 2 is connected to the barrel body 1 through the second adhesive layer 5, the sealing ring is squeezed to fill the gap between the barrel body 1 and the barrel lid 2.

[0025] Further, an upper bent edge 21 is provided on the barrel lid 2, and a lower bent edge 11 adapted to the upper bent edge 21 is provided on the barrel body 1. The upper bent edge 21 and the lower bent edge 11 jointly enclose a first L-shaped bending channel 8 and a second L-shaped bending channel 9. The first adhesive layer is provided in the first L-shaped bending channel 8, and the second adhesive layer 5 is provided in the second L-shaped bending channel 9.

[0026] Further, edges 12 are provided at one ends of the upper bent edge 21 and the lower bent edge 11 away from the opening 4.

[0027] The working principle of the present utility model is:

[0028] As Figure 1As shown in the figure, the first adhesive layer and the second adhesive layer 5 are respectively arranged in the first L-shaped bending channel 8 and the second L-shaped bending channel 9. Taking the first adhesive layer as an example, preferably, an annular groove is provided on the mounting table 7, and adhesives such as glue 71 or a sealing ring can be placed in the annular groove. The second adhesive layer 5 can be selected as glue 71. During installation, the convex part 6 on the bucket lid 2 is embedded into the opening 4 of the bucket body 1. When both the first adhesive layer and the second adhesive layer 5 use glue, an installation table 7 is provided on the inner wall of the bucket lid 2 or the bucket body 1 in the first L-shaped bending channel 8, and glue can be first injected into the installation table 7; an installation table 7 can also be provided on the inner channel in the second L-shaped bending channel 9 or the inner wall of the bucket body 1, and similarly, glue is injected into the installation table 7. At this time, the convex part 6 on the bucket lid 2 is embedded into the opening 4 of the bucket body 1, and the side wall of the bucket lid 2 will be bonded by the glue on the first L-shaped bending channel 8 and the glue on the second L-shaped bending channel 9. After the glue cures, the bucket body 1 and the bucket lid 2 are effectively connected and fixed. At this time, curling operations are performed on the upper curling edge 21 of the bucket lid 2 and the edge 12 provided on the lower curling edge 11 of the bucket body 1. The setting of curling can further prevent moisture from entering the first L-shaped bending channel 8 and the second L-shaped bending channel 9 through the gap between the upper curling edge 21 and the lower curling edge 11. As Embodiment 1, a sealing ring can be placed in the installation table 7 in the first L-shaped bending channel 8. At this time, one end of the sealing ring must extend out of the installation table 7. When the bucket lid 2 and the bucket body 1 are bonded through the second adhesive layer 5, the bucket lid 2 and the bucket body 1 will squeeze the sealing ring to deform, so that the sealing ring can fill the gap between the bucket lid 2 and the bucket body 1. This application replaces the existing welding method and connects and fixes the bucket lid 2 and the bucket body 1 through the cooperation of structures such as the first adhesive layer, the second adhesive layer 5, and the convex part 6, effectively avoiding the phenomenon of yellowing caused by the high-temperature welding process. In the above technology, the accommodation groove formed by enclosing the bucket lid 2 and the bucket body 1 constitutes the heating tank of the electric thermos flask. In addition, due to the limitation of the existing welding process, the shape of the opening 4 needs to be set as a trumpet shape, while this application can set the opening 4 as a straight cylinder shape with equal diameters. In the above technology, the bucket body is provided with openings at the upper and lower parts respectively. Only by connecting the bucket lid to any one of the openings, that is, the bucket lid and the bucket body enclose a space for accommodating liquid. The main design concept of this application lies in the connection method between the bucket lid and the bucket body.

[0029] Although the present invention has been described in detail with reference to the above embodiments, it is obvious to those skilled in the art through the present disclosure that various changes or modifications can be made to the present invention without departing from the principle and spirit scope of the present invention defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, rather than to limit the present invention, and the scope of protection is defined by the content of the claims.
