Detailed Description
The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work are within the scope of the present invention based on the embodiments of the present invention.
Referring to fig. 1 to 3, a steam generator includes a metal bottom case 1, an electric heating tube 2 and a metal top case 3, wherein a protrusion 11 is disposed at the top of an opening of the metal bottom case 1 along the direction of the opening, a plurality of recesses 12 recessed into the metal bottom case 1 are disposed on the side wall of the protrusion 11, the metal top case 3 is fastened to the metal bottom case 1, the shape of the inner side wall of the bottom of the metal top case 3 matches the shape of the protrusion 11, and the design has the advantage that the contact area between the metal bottom case 1 and the metal top case 3 is larger, and the connection is more stable.
The electric heating tube 2 is spirally arranged at the bottom of the metal bottom shell 1, so that the bottom space of the bottom shell can be utilized to the maximum, the electric heating tube 2 with the maximum length can be accommodated in a limited space, and the overall heating efficiency is improved.
The metal top shell 3 is provided with a water spray opening 31 facing the direction of the electric heating tube 2, the middle position of the metal top shell 3 is provided with a steam outlet 32, as the metal top shell 3 and the metal bottom shell 1 are both made of metal materials, the heat transfer performance of the metal materials is better, when the electric heating tube 2 is heated, heat is rapidly transferred to the metal top shell 3 from the metal bottom shell 1, the metal top shell 3 and the metal bottom shell 1 are rapidly heated to the temperature close to the electric heating tube, therefore, the internal temperature of the closed space between the metal top shell 3 and the metal bottom shell 1 is very high and is much higher than that of the traditional steam generator, and the position of the water spray opening 31 and the position of the electric heating tube 2 extend the farthest vaporization heating time, which is beneficial to absorbing more heat, when water is not contacted with the electric heating tube, the water is completely vaporized and is output from the steam outlet 32, the vaporization efficiency of the product is improved, the full vaporization of water is ensured, the electric heating pipe is prevented from contacting with the water, the service life of the product is prolonged, and the product has high practicability.
