[0025] Example: As attached Figure 1 To Attachment Fig.10 As shown: The invention provides a fumigation device for knee osteoarthritis.

[0026] like Figure 1-5As shown, a fumigation device for knee osteoarthritis comprises a wrapping shell 10 for wrapping a knee joint and a fumigation device 11 arranged on the wrapping shell 10. The inner cavity of the wrapping shell 10 is provided with a heating layer 12, an inflatable liner 13 and a guide needle 14. The inflatable liner 13 has a plurality of inflatable cavities 15 arranged at intervals. The inflatable liner 13 is wrapped around the heating layer 12. The heating layer 12 is connected to the guide needle 14. A smoke outlet 16 is provided on the inflatable cavity 15. The guide needle 14 passes through the smoke outlet 16. The smoking device 11 includes an inner smoke hole 17 and an outer smoke hole 18. The inner smoke hole 17 corresponds to the inflation cavity 15 one by one and is connected to each other. The outer smoke hole 18 is connected to the inner cavity of the wrapping shell 10. A first rotating ring 19 and a second rotating ring 20 are provided on the smoking device 11. The first rotating ring 19 has a first hole 21, and the second rotating ring 20 has a second hole 22. The first rotating ring 19 rotates to alternately open the inner smoke hole 17, and the second rotating ring 20 rotates to alternately open the outer smoke hole 18.

[0027] In the present embodiment, it also includes a strap connected to the wrapping shell 10 and an elastic pad 23 arranged inside the wrapping shell 10. When using the present device, the strap is tied to the knee joint so that the wrapping shell 10 wraps the knee joint, the elastic pad 23 directly contacts the skin, and a certain interval is formed between the inflatable lining 13 and the skin. In the present embodiment, a smoke generating device is provided inside the fumigation device 11. When the fumigation device 11 is started, the first rotating ring 19 is adjusted so that the first hole 21 on the first rotating ring 19 is aligned with the inner smoke hole 17. The generated smoke flows into the inflation cavity 15 through the inner smoke hole 17 and is sprayed toward the knee joint through the smoke outlet 16 on the inflation cavity 15. The smoke is discharged more evenly and can be evenly sprayed around the knee joint.

[0028] The first rotating ring 19 rotates, and the inner smoke holes 17 are connected to different inflation chambers 15 in sequence. The smoke is sprayed toward the knee joint through the inflation chambers 15 at different positions, and the smoke wraps better. In addition, when the smoke enters the corresponding inflation chamber 15, the inflation chamber 15 itself expands to a certain extent. The expansion action produces a certain disturbance to the airflow outside the inflatable liner 13, and the smoke and air produce convection, so that the smoke can be evenly distributed in the air.

The external smoke hole 18 is intermittently connected to the inner cavity of the package shell 10, and the smoke can leak to the outside through the gap. The smoke from the external smoke hole 18 is intermittently replenished into the inner cavity of the package shell 10 to maintain the amount of smoke in the cavity.

[0030] The heating layer 12 generates heat, and the heat is transferred to the guide needle 14. When the smoke flows through the smoke outlet 16, the guide needle 14 heats the smoke, and the guide needle 14 performs heating therapy on the important position of the knee joint.

[0031] In this embodiment, the heating layer 12 uses a heating resistor wire, and the heating resistor wire is electrically connected to a power source. The surface of the heating resistor wire is wrapped with a fireproof material, and a heat-conducting material is embedded in the fireproof material. The heat-conducting material is connected to the guide needle 14.

Two adjustment plates 25 are arranged on the diverter plate 27 to cover the second air inlet 29. The adjustment device is arranged on the shell 24 and drives the two adjustment plates 25 to move away from or close to each other.

[0033] In this embodiment, the smoke generator is arranged at the first air inlet 28. When the regulating device controls the two regulating plates 25 to move away from each other, the air inlet area of ​​the second air inlet 29 increases, and the ambient wind passes through the second air inlet 29 and mixes with the smoke. Since the air inlet surface of the second air inlet 29 increases, the smoke concentration is reduced. When the regulating device controls the two regulating plates to move closer to each other, the air inlet surface of the second air inlet 29 decreases, and the smoke concentration is increased.

The second rod has a cavity in which an elastic component is arranged. The first rod slides in the cavity of the second rod and is connected to the elastic component. When the elastic telescopic rod 34 is compressed, the first rod compresses the elastic component.

[0038] In this embodiment, the electric telescopic rod is extended and retracted to drive the adjustment ring 35 to rotate relative to the annular plate 30. The adjustment ring 35 pushes the slider 33 to move in the slide groove 32 through the elastic telescopic rod 34, and the slider 33 drives the adjustment plate 25 to slide.

[0045] The adjusting ring 35 rotates to drive the cover 41 and the elastic telescopic rod 34 to move together. The adjusting ring 35 pushes the slider 33 to move in the slide groove 32 through the elastic telescopic rod 34, and the slider 33 drives the adjusting plate 25 to slide.
