Vapor generator

The utility model relates to a vapor generator which comprises a vapor generator chamber (3) which is formed by closing of a shell body (1) and a cover plate (2). A plurality of vapor outlets (4) are arranged on two sides of the bottom of the vapor generator chamber (3). A U-shaped heating bar (5) is arranged inside the chamber. The inner surface (6) of a bottom plate is a cone-shaped structural body. The top ends of the vapor outlets (4) are higher than the diameter of the heating bar (5). A tendon (8) which is shaped like a ring is arranged on the U-shaped heating bar (5), and a small notch is opened on a part of the tendon (8). The top portion of the tendon and the cover plate (2) separate the vapor generator into two cavities, the middle part is a primary vaporization cavity, and the outer ring is a secondary vaporization and vapor channel. And the whole vapor generator is fixedly arranged on the top face of a hot platen (7). The Vapor generator can more evenly and effectively vaporize water which enters
