The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings, but it is understood that the scope of the present invention is not limited by the specific embodiments. As shown in Figs. 1 and 2, the steam cleaner boiler includes a barrel-shaped outer casing 2 and a barrel-shaped heat exchanger 1, which is sleeved inside the outer casing 2 and which are open to each other. One side of the outer casing 2 is provided with a water inlet joint 21, and a steam nozzle 22 is provided at the top. An electric heating body 15 is attached to the bottom of the heat exchanger 1. The outer surface of the heat exchanger body 1 is spirally opened with a groove 12, and the groove 12 and the inner wall of the outer casing 2 constitute a steam generating chamber, and one end of the groove 12 is a water inlet 11, the water inlet 11 and the outer casing The water inlet joint 21 on the second side communicates with the other end through a connection hole 13 formed in the heat exchange body 1 and communicates with a cavity inside the heat exchange body 1. The cavity in the heat exchange body is a secondary evaporation chamber 14, which Secondary evaporation chamber 14 with steam The nozzles 22 are in communication. When the boiler is in operation, water enters the heat exchanger body groove 12 (steam generating chamber) through the water inlet joint 21, and the heat generated by the electric heating body 15 is transferred to the steam generating chamber through the heat exchanger body 1 to change the water inside thereof. Into steam. A small amount of unvaporized water in the steam enters the secondary evaporation chamber 14 through the connection hole 13, and is again heated by the heat in the heat exchanger 1 to be completely vaporized and then ejected through the steam vent 22 in the outer casing 2. Since the steam generating chamber is directly opened on the heat exchanger, the steam generating chamber of the present invention has a larger contact area with the heat exchanger than the steam generating chamber used in the prior art, and the heat exchange is more. To be sufficient, the heat exchange rate of the boiler is higher. At the same time, due to the addition of the secondary evaporation chamber, the remaining heat of the heat exchanger can be used to completely vaporize a small amount of incompletely vaporized and partially recondensed liquid water in the steam, thereby avoiding the water leakage problem of the steam cleaner. The above disclosure is only one specific embodiment of the present invention, but the present invention is not limited thereto, and any changes that can be made by those skilled in the art should fall within the protection scope of the present invention.
