[0026] like Figure 1 , Figure 2 , Fig. 9 , Fig.10 As shown, the flushing waste liquid collection mechanism 5 includes a rectangular frame 501, a soft plastic frame 502, a fixed box 503 and a waste liquid collection box 504. The rectangular frame 501 is fixed on a rectangular plate 801, the inner bottom of the rectangular frame 501 is inclined, and a liquid inlet 505 is provided on the inner bottom of the rectangular frame 501.

[0027] like Fig. 9 , Fig.10 As shown, the soft plastic frame 502 is fixed on the end surface of the rectangular frame 501 , the fixed box 503 is fixed on the bottom of the rectangular frame 501 , and the waste liquid collection box 504 is disposed in the fixed box 503 and is slidably connected to the fixed box 503 .

[0028] During specific use, the patient sits in front of the flushing device and adjusts the height of the pressure nozzle 901 according to the height of the patient's eyes. The motor 601 is started, and the motor 601 drives the clamp ring 602 to rotate. The clamp ring 602 drives the clamp ring 2 603 and the screw 604 to rotate through the transmission belt. The screw 604 drives the rectangular column 701 and the fixed plate 702 to move upward. The fixed plate 702 drives the flushing liquid control mechanism 3, the automatic eye flushing mechanism 4 and the flushing waste liquid collection mechanism 5 to move upward together, that is, drives the pressure nozzle 901 to move upward until the pressure nozzle 901 and the patient's eyes are at the same horizontal height, and then unscrew the screw cap on the liquid inlet pipe 301, add flushing liquid into the liquid inlet pipe 301, and the flushing liquid enters the rectangular box 302 through the liquid inlet pipe 301.

[0029] Then, the distance between the two pressure nozzles 901 is adjusted according to the patient's eye distance. If you want to reduce the distance between the two pressure nozzles 901, you only need to rotate the screw rod 805. The screw rod 805 drives the circular block 806 to move backward, and the circular block 806 drives the connecting rod 807 to rotate, so that the angle between the two connecting rods 807 becomes smaller, and the two connecting rods 807 drive the two L-shaped plates 802 to move from both ends to the middle, and the L-shaped plates 802 drive the sliding blocks 803 to move along the slide groove 808 from both ends to the middle, and the L-shaped plates 802 drive the pressure nozzles 901 to move from both ends to the middle through the support blocks 903, so as to reduce the distance between the two pressure nozzles 901. After adjusting to the appropriate position, stop rotating the screw rod 805. If you want to increase the distance between the two pressure nozzles 901, you only need to rotate the screw rod 805 in the opposite direction.

[0030] The patient places his face against the soft rubber frame 502 and aligns his eyes with the pressure nozzle 901 for cleaning. It is only necessary to start the motor 2 304. The motor 2 304 drives the screw 3 303 to rotate. The screw 303 drives the push plate 305 to move forward to push the flushing liquid into the hose 306. The flushing liquid enters the rotating ring 902 through the hose 306 and then enters the pressure nozzle 901 from the rotating ring 902. The flushing liquid passes through the concave groove 906 in the pressure nozzle 901 and is then sprayed out from the outlet to flush the patient's eyes. If the flushing pressure is felt to be relatively high, it is only necessary to turn off the motor 2 304 and rotate the rotating ring 902 again. The rotating ring 902 drives the fixed column 904 to rotate, and the fixed column 904 drives the pressure regulating column 905 to move backward, so that the water inlet of the internal concave groove 906 is reduced and the water outlet is increased, thereby reducing the water pressure. If the water pressure is to be increased, it is only necessary to rotate the rotating ring 902 in the opposite direction.

[0031] The waste liquid left over from flushing will be collected on the inner bottom of the rectangular frame 501, flow into the liquid inlet 505 along the slope of the inner bottom, and flow into the waste liquid collection box 504 below through the liquid inlet 505. When the waste liquid needs to be processed, the waste liquid collection box 504 only needs to be pulled out of the fixed box 503 and poured out.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0033] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
