     As shown in  FIGS. 3-5 , in some embodiments, the heating tube  7  comprises two support pins. The heating tube  7  is arranged in the water storage cavity  14  with bilateral symmetry through the two support pins. The heating tube  7  has more stability and vibration of the water boiler during transportation can be significantly reduced. More specifically, as shown in  FIG. 4 , in some embodiments, the heating tube  7  has a curve structure. The curve structure is shaped as a Chinese character “ ”. As shown in  FIG. 3 , in some embodiments, the tank cover  6  and the second pipe  13  are formed in integrity, and therefore the tank assembly  1  has a simpler structure. 
     As shown in  FIG. 2 , in some embodiments, the connection between the expansion tank  16  and the water flow assembly  19  are detachable. In other embodiments, the expansion tank  16  and the water flow assembly  19  are formed in integrally, and therefore reducing the complicity of the water boiler, and facilitating the installation of the water boiler. The expansion tank  16  is configured to absorb the expansion water, which is caused when the water in the tank assembly  1  is heated and expanded. The exist of the expansion tank  16  avoids the spillover of the heated water and protects the users from getting hurt. 
     As shown in  FIGS. 2-5 , in some embodiments, the casing assembly  3  comprises a casing seat  11 , a casing cover  4 , and a casing side plate. The casing seat  11  is configured to support and attach the tank assembly  1 . As shown in  FIG. 3  and  FIG. 5 , in some embodiments, the casing assembly  3  further comprises a grounded plate  12 , which is located on and removable to the casing seat  11 . As shown in  FIG. 3 , in some embodiments, the grounded plate  12  comprises an attachment clip  21 . The casing seat  11  comprises a through hole adapted to the attachment clip  21 . The grounded plate  12  is connected to the casing seat  11  via the coupling of the attachment clip  21  and the through hole. 
     As shown in  FIG. 3 , in some embodiments, the casing assembly  3  comprises a support plate  10 , which is located on the bottom of the tank body  9  and extended through the insulation component  5 . An overhang of the support plate  10  extending through the insulation component  5  is connected to the casing assembly  3 . The support plate  10  and the tank body  9  are NI-Au welded, so as to reduce the effect of the welding on the tank body  9 . 
     The above description is only preferred embodiments of the disclosure, and various modification and changes may be made by those skilled in the art within the spirit of the scope of the disclosure. Any modifications, equivalent substitutions, improvements made within the spirit and principles of the present disclosure shall be deemed within the scope of the present disclosure.
