A transparent cover 3 is fixedly connected to the top of the exhaust port 4, so that the steam generated from the boiler 1 can be observed. One side of the transparent cover 3 penetrates and is fixedly connected to a guide pipe 18. An air inlet 17 is opened on the front side of the guide pipe 18. A heat preservation sleeve 5 is fixedly connected to the outer wall of the guide pipe 18, which can perform heat preservation treatment on the just-generated steam and improve the utilization rate of the residual temperature. One side of the guide pipe 18 is fixedly connected to a heat conduction copper pipe 14. An air outlet 16 is opened on the front side of the bottom of the heat conduction copper pipe (14). An activated carbon filter screen 15 is arranged on the inner wall of the bottom of the heat conduction copper pipe 14, which can filter harmful gases in the steam. A high-temperature resistant blower 6 is fixedly connected to the outer wall at the rear side of the guide pipe 18, preventing the pressure in the boiler 1 from being too high due to excessive steam and causing an explosion. A heat preservation component is arranged at the rear side of the guide pipe 18.
[0033] Combined with Figure 2 , an exhaust valve 10 is fixedly connected to the outer wall of the bottom of the heat conduction copper pipe 14. When the temperature of the water measured by the temperature detector reaches the standard, the exhaust valve 10 is opened to discharge the steam. And the heat conduction copper pipe 14 penetrates through a heat preservation water tank 7. An activated carbon filter screen 15 is arranged on the inner wall of the bottom of the heat conduction copper pipe 14, which can filter harmful gases contained in the steam. An air outlet 16 is opened on the front side of the bottom of the heat conduction copper pipe 14, and the discharged steam is discharged through the air outlet 16. One side of the transparent cover 3 penetrates and is fixedly connected to a guide pipe 18. A high-temperature resistant blower 6 is fixedly connected to the outer wall at the rear side of the guide pipe 18 to transport the steam and prevent the pressure in the furnace from being too high. The heat conduction copper pipe 14 is fixedly connected to the inner wall of the heat preservation water tank 7.
[0034] Combined with Figure 1 and Figure 3, the heat preservation component includes a heat preservation water tank 7. The heat preservation water tank 7 is fixedly connected through the air guide pipe 18. The inner wall of the heat preservation water tank 7 is fixedly connected with a heat conduction copper pipe 14, and the heat conduction copper pipe 14 is fixedly connected with the air guide pipe 18. Through the heat conduction copper pipe 14, the temperature generated by the steam can be transmitted to the cold water to recover the residual heat. The front outer wall of the heat preservation water tank 7 penetrates and is fixedly connected with a temperature detector 9, which is used to detect the temperature of the water in the heat preservation water tank 7 to indirectly reflect the recovery situation of the residual heat.

[0035] Working principle: When the boiler 1 generates steam, the user can start the high-temperature resistant blower 6, and let the steam enter the air guide pipe 18 through the exhaust port 4. At this time, the steam situation can be observed through the transparent cover 3, and the heat preservation sleeve 5 on the outer wall of the air guide pipe 18 can reduce the loss of residual heat. Then the steam is transported to the heat conduction copper pipe 14. During this period, the user can open the water inlet valve 8 to let the cold water enter the heat preservation water tank 7 through the water inlet pipe 12 to wait for the recovery of the residual heat. When the steam dissipates heat in the heat conduction copper pipe 14, watch the temperature detector 9. When the temperature reaches the standard, open the exhaust valve 10 to discharge the steam filtered by the activated carbon filter net 15 from the air outlet 4. Then open the drain valve 11 to discharge the water that has recovered the residual heat from the drain pipe 13 for utilization. After the water that has recovered the residual heat is drained, repeat the operation.
