[0024] The effect achieved by the whole embodiment 1 is that the wear-resistant layer 310 of the protective cover 3 is made of plastic material, which can effectively prevent the internal equipment from being damaged due to external impact or wear and tear, the heat preservation layer 320 is made of polyurethane foam material, which can heat the water ring vacuum pump 6, thereby slowing down the freezing speed of the internal water, reducing the use cost of the steam generator 2, the sound insulation layer 330 can reduce the working time of the internal equipment, and provide a good working and living environment for people near the device. After the steam generator 2 is started, the generated air is transported to the inside of the heat exchange box 10 through the steam conveying pipe 14, the filter pipe 13 and the flow rate detector 12. The heat exchange box 10 can heat the water in the water ring vacuum pump 6 through heat conduction, so that the water is kept at a certain temperature, preventing the water ring vacuum pump 6 from being damaged due to water freezing. The steam with residual heat can return to the inside of the steam generator 2 through the steam return pipe 11, which not only reduces the heat pollution to the air, but also reduces the energy consumption of the steam generator 2.
