[0006] Furthermore, one end of the bracket is connected to the top of the ring suction box.
[0007] Furthermore, the minimum distance between the edge of the vertical brush and the ring suction box is 2-5 mm, the bristles are vertically downward, and the ends of the bristles are at the same height as the bottom of the buffer pad.
[0008] Furthermore, the height of the brush plate end of the vertical brush is consistent with the bottom of the ring suction box.
[0009] Furthermore, the lowest point of the horizontal brush is at the same height as the bottom of the buffer pad.
[0010] Furthermore, the brush plate is connected to the brush head.
[0011] Compared with the prior art, the beneficial effects of the utility model are: first, the design is simple and easy to use; second, the pure titanium metal denture is cleaned by brushes in two directions and then recovered by a vacuum cleaner, with high powder cleaning efficiency, and only the titanium powder that is exposed to high temperature near the finished product and cannot be directly reused is recovered, without affecting the direct use of the remaining titanium powder; third, the escape of titanium alloy powder can be prevented by the surrounding vacuuming method, which is beneficial to protecting the health of the operator.
