[0003] The fumigation instrument generally comprises a steam generating device, a spray head and a cold and hot steam pipeline connecting the steam generating device and the spray head, and the cold and hot steam reaches the spray head through the cold and hot steam pipeline.

[0004] A rotating and swinging part is arranged on the cold and hot steam pipeline, which can realize multi-angle treatment, but after long-term use, the connection position between the two parts is prone to looseness, so that the cold and hot steam pipeline cannot be fixed at will, affecting the use of the fumigation instrument. SUMMARY

[0005] In order to enable the cold and hot steam pipeline to be fixed at will after adjusting the angle, the present application provides a cold and hot steam pipeline and a fumigation instrument.

[0006] The cold and hot steam pipeline and the fumigation instrument provided by the present application adopt the following technical scheme:

[0007] A cold and hot steam pipeline comprises an upper pipeline, a lower pipeline and a swinging part for connecting the upper pipeline and the lower pipeline, the swinging part comprises an inner connecting sleeve connected with the upper pipeline and an outer connecting sleeve connected with the lower pipeline, the inner connecting sleeve is rotatably and sealingly embedded in the outer connecting sleeve, the outer connecting sleeve is further provided with a first damping assembly, the first damping assembly comprises an adjusting plate connected with the outer connecting sleeve, a first damping elastic piece abutting against one end of the adjusting plate and a first friction plate for increasing the abutment of the outer connecting sleeve and the inner connecting sleeve, the first damping elastic piece has a tendency to force the first friction plate to abut against the inner connecting sleeve.

[0008] By adopting the technical scheme, the swing part can swing the upper pipeline relative to the lower pipeline, the inner connecting sleeve and the outer connecting sleeve can seal the connecting position of the upper pipeline and the lower pipeline, and can rotate relative to each other to realize the swing of the upper pipeline, the first damping elastic piece can improve the rotating friction between the outer connecting sleeve and the inner connecting sleeve, one end of the first damping assembly abuts against the adjusting plate, and under the reaction force, the first damping assembly can push the first friction sheet to abut against the inner connecting sleeve, so that the inner connecting sleeve and the outer connecting sleeve are kept in a certain friction, and the problem that the inner connecting sleeve and the outer connecting sleeve are prone to loosening is reduced. On the one hand, when the force applied by the staff to the upper pipeline is greater than the friction resistance, the upper pipeline can rotate relative to the lower pipeline, and on the other hand, when the upper pipeline is not subjected to additional external force, the first friction sheet can be fixed at will under the action of the first friction sheet.

[0009] Optionally, the outer connecting sleeve is provided with an adjusting groove, the adjusting plate is threadedly connected with the groove wall of the adjusting groove, the first damping elastic piece is located in the adjusting groove, one end of the first damping elastic piece towards the first friction sheet is fixed with a first baffle, the first baffle abuts against the first friction sheet, the outer connecting sleeve is provided with a first limiting groove, and the first friction sheet is fixed with a first limiting column, one end of the first limiting column passes through the first baffle and is located in the first limiting groove; when the adjusting plate rotates, the first damping elastic piece can increase or decrease the elastic potential energy.

[0010] By adopting the technical scheme, the adjusting groove can accommodate the first damping elastic piece, and the adjusting plate can rotate relative to the adjusting groove, so that the first damping elastic piece can be compressed or relaxed. The first baffle can uniformly push the force of the first damping elastic piece to the first friction sheet, increase the contact surface of the first damping elastic piece and the first friction sheet, and the first limiting column can limit the rotation of the first friction sheet, so that the inner connecting sleeve does not drive the first friction sheet to rotate when rotating, avoiding the problem of slipping, to ensure the friction between the first friction sheet and the inner connecting sleeve. When the upper pipeline is loose and does not have external force, the adjusting plate can be rotated towards the adjusting groove, the adjusting plate can compress the first damping elastic piece, thereby increasing the elastic potential energy of the damping elastic piece, so that the first damping elastic piece can further compress the first friction sheet to the inner connecting sleeve, improve the friction damping of the first friction sheet to the inner connecting sleeve, and make the upper pipeline can be fixed at will. When the staff needs to exert a large force to rotate the upper pipeline, the adjusting plate can be reversely rotated, so that the adjusting plate moves away from the adjusting groove, so that the first damping elastic piece can be relatively relaxed, thereby the staff can realize the random fixing of the upper pipeline without too much force.

When the upper pipe swings in one direction, the center of gravity of the upper pipe changes, and the upper pipe tends to swing more in this direction, so as the swing amplitude of the upper pipe increases, the inner connecting sleeve and the outer connecting sleeve are prone to loosening, and the damping elastic sheet pushes the second transmission block to indirectly provide the upper pipe with a counteracting force in the opposite direction, so as to realize damping balance, and the staff can push the upper pipe with a force of about the same size regardless of the direction of swing.

In the embodiment, the first damping assembly 4 has two, which are located on both sides of the inner connecting sleeve 32, and the two first damping assemblies 4 are the same in structure but different in position.

[0053] Referring to Figure 4 and Figure 5When the inner rotating sleeve rotates, the guide protrusion 572 moves in the accommodation slot 55, which pushes the damping elastic sheet 56 to deform, according to the principle of reaction force.
