Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1:

referring to fig. 1, 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, an instant heating type safe and energy-saving heating body, including casing 1, inner tube 2 has been run through to casing 1's inside, casing 1's internally mounted has spiral helicine heating tube 3, and inner tube 2 is located heating tube 3 inboard, casing 1's internally mounted has spiral helicine outer tube 4, and outer tube 4 is located heating tube 3's the outside, casing 1 is all worn out at the both ends of outer tube 4, the one end of outer tube 4 is passed through return bend 5 and is connected with the one end of inner tube 2.

The inner tube 2 is internally provided with a spiral sheet 6, the diameter of the inner tube 2 is larger than that of the outer tube 4, cast aluminum is filled between the spiral coils of the outer tube 4 and the heating tube 3, and the heating tube 3 is provided with one or more groups.

Example 2:

referring to fig. 1, 2, 3, 4, 5, 8, 9, 10, 11, 12, an instant heating type safe and energy-saving heating body, including casing 1, inner tube 2 has been run through to casing 1's inside, casing 1's internally mounted has spiral helicine heating tube 3, and inner tube 2 is located heating tube 3 inboard, casing 1's internally mounted has spiral helicine outer tube 4, and outer tube 4 is located heating tube 3's the outside, casing 1 is all worn out at the both ends of outer tube 4, the one end of outer tube 4 is passed through return bend 5 and is connected with the one end of inner tube 2.
