Title:
JET PRESSURE ADJUSTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/003989
Kind Code:
A1
Abstract:
The present invention relates to the technical field of medical apparatus and instruments, and in particularly to a jet pressure adjusting apparatus, comprising a high-pressure tube for liquid flowing and an adjusting member for adjusting liquid jet form and pressure. One end of the high-pressure tube is provided with a first jet orifice for jetting the liquid from the high-pressure tube. The adjusting member comprises a rotating shaft part and a shaping part. The rotating shaft part is disposed at one side of the high-pressure tube. The shaping part is provided with a second jet orifice, and the number of the second jet orifice is not limited to one. The shaping part could, by means of the rotating shaft part, rotate along the circumferential direction and/or move along the axial direction of the rotating shaft part to adjust the relative position of the second jet orifice and the first jet orifice. By providing the adjusting member in the present invention, the second jet orifice can, by means of the rotating shaft part, move along the axial direction of the rotating shaft part to adjust the distance to the first jet orifice, and further more can, by means of the rotating shaft part, rotate relative to the high-pressure tube to change the relative position of the axis of the second jet orifice and the axis of the first jet orifice, so that liquid of different divergence angles and jet pressures is jetted from the second jet orifice.
