3. The seamless inner container for the water heater as claimed in claim 2, wherein: the periphery of the upper drainage pipe (31) is sleeved with a porous fiber sleeve (34) at a position corresponding to the drainage hole (33), and the fiber sleeve (34) is used for adsorbing silicate precipitated during the heating of cold water in the liner body (1), so that the adhesion of the silicate in the drainage hole (33) is reduced, and the normal drainage of hot water by the drainage pipe (12) is further ensured.
4. The seamless inner container for the water heater as claimed in claim 3, wherein: the fiber sleeve (34) is provided with a through hole (35) at a position corresponding to the drain hole (33), the diameter of the through hole (35) is larger than that of the drain hole (33), and the through hole (35) is used for preventing the fiber sleeve (34) from adsorbing excessive silicate and then influencing the water inflow of the drain hole (33), so that the drain pipe (12) is further ensured to normally drain hot water.
5. The seamless inner container for the water heater as claimed in claim 4, wherein: a vacuum cavity (36) is arranged in the upper drainage pipe (31) below the fiber sleeve (34), and the vacuum cavity (36) is used for isolating cold water in the upper drainage pipe (31) at the corresponding position of the vacuum cavity (36) from absorbing heat, so that silicate is precipitated and then adhered to the inner wall of the upper drainage pipe (31), and the water drainage pipe (12) is further ensured to normally discharge hot water.
6. A water heater, characterized in that: the water heater adopts the seamless inner container for the water heater as claimed in any one of claims 1 to 5; the water heater comprises a cylindrical shell (17) with two closed ends; the water inlet pipe (11) and the water outlet pipe (12) penetrate through and extend to the outside of the shell (17); be equipped with foam cushion (18) between shell (17) both ends and inner bag body (1), foam cushion (18) are used for preventing that inner bag body (1) transportation in with shell (17) collision deformation from causing and leaking the hidden danger.
