[0026] Reference Figure 3 The inside of pipe body 1 is fixedly installed with connecting pipe 6, the inside of connecting pipe 6 is provided with baffle 7, the middle part of baffle 7 is provided with through hole, and the bottom of threaded rod 11 is fixedly installed with valve core 121 used in cooperation with the through hole.

[0027] Further, when using, rotating disc 12 is rotated, threaded rod 11 connected with rotating disc 12 is rotated, so that threaded rod 11 moves up and down, and then valve core 121 is also moved up and down, so that steam delivery can be opened or closed.

[0028] Reference Figure 2One end of the tube body 1 is connected to the air inlet pipe 2, and a pressure relief plate 3 is fixedly provided inside the air inlet pipe 2. A pressure relief hole 4 is opened inside the pressure relief plate 3. The pressure relief plate 3 is a prior art and will not be disclosed in detail here. The purpose of regulating the pressure is achieved by changing the flow area, thereby reducing the steam pressure and reducing the pressure first.

[0029] refer to Figure 3 An arc-shaped tube 5 is fixedly installed at one end of the pipe body 1 near the air inlet pipe 2, and the air inlet pipe 2 is connected to the connecting pipe 6 through the arc-shaped tube 5. The arc-shaped tube 5 can effectively reduce the pressure of the pipeline and has a specific arc-shaped structure. This design enables it to withstand and disperse pressure and reduce the steam flow rate.

[0030] refer to Figure 3-Figure 5 The end of the connecting pipe 6 away from the air inlet pipe 2 is connected to the air outlet pipe 13, and the surface of the air outlet pipe 13 is surrounded by a cooling pipe 14. The surface of the cooling pipe 14 is fixedly installed with a heat dissipation fin 16, and one end of the cooling pipe 14 is fixedly connected to the water inlet pipe 15. The top of the water inlet pipe 15 passes through the upper surface of the tube body 1, and the other end of the cooling pipe 14 is connected to the atomizing nozzle 17 inside the air outlet pipe 13. A steam-water separation filter plate 19 is fixedly installed inside the air outlet pipe 13 and on one side of the atomizing nozzle 17. The steam-water separation filter plate 19 is a prior art and will not be disclosed in detail here.

[0031] Furthermore, during use, when high-temperature steam enters the exhaust pipe 13, cooling water is injected into the cooling pipe 14 through the water inlet pipe 15 to pre-cool the steam. The heat dissipation fins 16 use the principles of heat conduction and convection to transfer heat from the high-temperature area to the low-temperature area to achieve a cooling effect and improve the cooling effect. Subsequently, the cooling water is atomized and sprayed out through the atomizing nozzle 17 to further cool the steam to achieve a usable stability. Finally, the water vapor is filtered through the steam-water separation filter plate 19 to improve the use effect of the steam.
