step 1, preconditioning the cleaning brush (54):
the handheld shell (1) is held by a hand, then the distance adjusting lug (43) is rotated to drive the distance adjusting disc (41) and the distance adjusting inclined hole (42) to rotate, the distance adjusting inclined hole (42) acts on the roller column cavity (55) to drive the output device (5) to slide along the underlying sliding hole (12a), and the distance between a pair of cleaning brushes (54) is adjusted to adapt to cathode-type color ultrasonic probes with different thicknesses;
during the movement of the output device (5), the compression spring (33b) drives the telescopic sleeve (33) to enable the input bevel gear (33c) to be in transmission connection with the output bevel gear (57) at all times;
step 2, rubbing and cleaning the cathode type color ultrasound probe:
the cathode type color ultrasound probe is inserted into the upper cavity (13) through the upper opening (13 a);
holding the hand-held housing (1) by hand, so that the input rotating wheel (15a) and the free rotating wheel (15b) are in contact with a horizontal plane;
pushing the hand-held housing (1) to advance to enable the input rotating wheel (15a) and the free rotating wheel (15b) to rotate;
the right end face of the input rotating wheel (15a) acts on the sliding sleeve ring (23) to drive the speed regulating device (2) to rotate;
the driving bevel gear (24) drives the driven bevel gear (32) and the sliding inner cylinder (32b) to rotate, and further the telescopic sleeve (33) and the input bevel gear (33c) rotate;
the input bevel gear (33c) drives the output bevel gear (57), the driving roller column (56), the driven roller wheel (52), the brush connecting rod (53) and the cleaning brush (54) to rotate, and the cleaning brush (54) performs friction cleaning on the female color ultrasound probe.
2. The method for cleaning a cathode-ray color ultrasound probe according to claim 1, wherein: further comprising the steps of:
before step 1, a disinfectant is sprayed onto the cleaning brush (54) through the upper opening (13 a).
