[0023] Please see Figure 1-6 One embodiment provided by this utility model:

[0024] A cross-shaped fumigation frame includes a footrest 1 for support and a telescopic rod 2. The telescopic rod 2 is connected to the surface of the footrest 1 via damping, allowing for extension and retraction to change the overall working height. A first limiting shaft 3 is fixedly connected to the surface of the telescopic rod 2, allowing a rotating block 4 to rotate. The rotating block 4 is also connected to the surface of the first limiting shaft 3 via damping, allowing for rotation to change the direction of the ridge nozzle 8.

A steam delivery hose 6 is provided on the surface of the steam inlet trough 5, allowing steam generated by the fumigation device 7 to be delivered... The steam is delivered into the steam inlet trough 5. A fumigation device 7 is installed at the end of the steam delivery hose 6 furthest from the steam inlet trough 5 to generate steam. A ridge spray pipe 8 is fixedly connected to the surface of the steam inlet trough 5 for fumigating the spine. The surface of the ridge spray pipe 8 has steam injection holes 9 for spraying steam. Silicone plugs 10 are inserted into the surface of the steam injection holes 9 to seal them. A second limiting shaft 11 is fixedly connected to the surface of the ridge spray pipe 8 for rotating the first steam-passing rotary drum 13. A sealing ring 12 is fitted onto the surface of the second limiting shaft 11 to improve the sealing of the connection. A first steam-passing rotary drum 13 is rotatably connected to the surface of the ridge spray pipe 8. A steam turbine 13 is used to connect to a first shoulder nozzle 14. The first shoulder nozzle 14 is fixedly connected to the surface of the first steam turbine 13 for fumigating the shoulder area.

The sealing ring 12 is abutted to the inside of the first steam-passing rotary cylinder 13 via the connecting shaft 15. The first steam-passing rotary cylinder 13 can rotate on the surface of the ridge nozzle 8, so that the first shoulder nozzle 14 can rotate and fit the human body better. The connecting shaft 15 can rotate on the surface of the first steam-passing rotary cylinder 13. The connecting shaft 15 is used to connect the first steam-passing rotary cylinder 13 and the second steam-passing rotary cylinder 16. The sealing ring 12 improves the sealing performance of the connection between the ridge nozzle 8 and the first steam-passing rotary cylinder 13, and between the first steam-passing rotary cylinder 13 and the connecting shaft 15, preventing surface steam from overflowing.

[0028] Furthermore, the second steam-powered rotary cylinder 16 is rotatably connected to the surface of the connecting shaft 15 and the ridge nozzle 8, the second shoulder nozzle 17 is rotatably connected to the surface of the second steam-powered rotary cylinder 16 and the connecting shaft 15, the sealing ring 12 is abuttingly connected to the surface of the second steam-powered rotary cylinder 16 and the connecting shaft 15, and the neck nozzle 18 is rotatably connected to the surface of the second steam-powered rotary cylinder 16 via the third limiting shaft 19. The sealing ring 12 is abuttingly connected to the surface of the second steam-powered rotary cylinder 16 and the third limiting shaft 19. The second steam-powered rotary cylinder 16 can rotate on the surface of the connecting shaft 15, allowing the second shoulder nozzle 17 to rotate and better conform to the human body. The neck nozzle 18 can rotate on the surface of the second steam-powered rotary cylinder 16. The sealing ring 12 is used to improve the sealing performance of the connection between the connecting shaft 15 and the second steam-powered rotary cylinder 16, and the neck nozzle 18.

[0029] Furthermore, the sealing caps 20 are in multiple sets, used to seal one end of the first shoulder nozzle 14, the second shoulder nozzle 17, and the neck nozzle 18. The steam inlet sump 5 and the ridge nozzle 8 are connected by a passage. The first shoulder nozzle 14 is connected to the ridge nozzle 8 through the internal passage of the first steam-passing rotating cylinder 13. The second steam-passing rotating cylinder 16 is connected to the internal passage of the first steam-passing rotating cylinder 13 through the connecting shaft 15. The second shoulder nozzle 17 is connected to the internal passage of the neck nozzle 18 through the second steam-passing rotating cylinder 16. The passages are connected so that the steam generated by the fumigation device 7 can be delivered through the steam delivery hose 6 to the fumigation racks above the steam inlet sump 5 for fumigation of the human body.

[0030] Furthermore, the rotating protrusion 22 is rotatably connected to the surface of the connecting shaft 15 via the adjusting handle 23, and is rotatably connected to the surface of the connecting shaft 15 via the fixed shaft 21. The rotating protrusion 22 is abutted to the surface of the first steam inlet cylinder 13 and the second steam inlet cylinder 16. The neck nozzle 18 is fixedly connected to the surface of the ridge nozzle 8 via the rotating protrusion 22. Moving the adjusting handle 23 can drive the rotating protrusion 22 to move, rotating the rotating protrusion 22 between the first steam inlet cylinder 13 and the second steam inlet cylinder 16, so that the rotating protrusion 22 abuts between the two, thereby increasing the friction between the three and fixing their positions. At the same time, the first steam inlet cylinder 13 abuts against the surface of the second limiting shaft 11, and the second steam inlet cylinder 16 abuts against the surface of the third limiting shaft 19, thus fixing the positions of the ridge nozzle 8 and the neck nozzle 18.

[0031] Working principle: When using the tripod 1, first extend the telescopic rod 2 to a suitable height as needed. Rotate the rotating block 4 and the neck nozzle 18 to the appropriate angle, aligning them with the human shoulder and spine area. Remove the appropriate number of silicone plugs 10. Then, start the fumigation device 7 to generate steam. The steam is delivered to the steam inlet 5 through the steam delivery hose 6. The steam is dispersed through the spine nozzle 8 to the first shoulder nozzle 14, the second shoulder nozzle 17, and the neck nozzle 18, and then discharged through the steam outlet 9. Then, close the silicone plugs 10 and wait for one minute before contacting the fumigation frame. Then, as needed, pull the adjusting handle 23 to rotate the rotating protrusion 22 out from between the first steam cylinder 13 and the second steam cylinder 16. Then, rotate the first shoulder nozzle 14 and the second shoulder nozzle 17 to adjust to a suitable angle. Then, rotate the rotating protrusion 22 to engage between the first steam cylinder 13 and the second steam cylinder 16 to fix the overall position. Then, fumigation can be performed.
