This utility model discloses a vaginal irrigation device, relating to the field of medical device technology. The utility model includes a delivery tube, an irrigation tube, and a storage tank. A mesh tube is rotatably arranged along the circumference of the inner wall of the irrigation tube. An impeller is fixed to one end of the mesh tube near the delivery tube. Several diversion holes are evenly distributed in a circular array along the circumferential side of the irrigation tube, and these diversion holes are located along the rotation path of the mesh holes on the mesh tube. This utility model, by setting multiple diversion holes of different sizes on the circumferential side of the irrigation tube, gradually reduces the inner diameter of the diversion holes from near the inner wall of the irrigation tube to away from it. The further inward the diversion holes contract, the greater the water flow velocity at the outlet of the diversion holes. Consequently, the irrigation force of the irrigation fluid flowing out of the irrigation tube varies; a lower water flow velocity results in a weaker irrigation force, thus providing a gentler irrigation, while a higher water flow velocity provides a stronger irrigation force, effectively flushing away stubborn bacteria and improving the efficiency of vaginal irrigation.
