Spraying heat preservation vapor supplying device and generator apparatus using such device

A spraying heat preservation vapor supplying device, comprising:

• a heat preservation boiler having an inner chamber, an outer chamber surrounding the inner chamber and a compartment layer separating the inner chamber from the outer chamber;
• a high heat capacity material filled in the outer chamber;
• a heater, which is connected to the heat preservation boiler and heats the high heat capacity material, wherein heat of the high heat capacity material is transferred to the inner chamber through the compartment layer;
• a supplier tube having a first end disposed in the inner chamber of the heat preservation boiler;
• a liquid source, which is connected to a second end of the supplier tube, and supplies a liquid to the inner chamber through the supplier tube, so that the liquid absorbs heat of the inner chamber to generate a vapor;
• and
• a vapor outlet connected to the inner chamber, wherein the vapor is outputted through the vapor outlet,
• wherein a portion of the compartment layer close to the vapor outlet is formed with an inclined surface, so that the vapor is sprayed from the vapor outlet through a nozzle-like structure formed by the inclined surface and an inner camber of the heat preservation boiler.
