[0051] The liquid collecting bottle 50 is inserted into the fourth joint 15b; the liquid collecting bottle 40 is used to collect waste water; a negative pressure is formed in the liquid collecting bottle 40 in advance, for example, the air therein is pumped out by an air pump and then sealed.

[0052] The upper end of the cylinder 30 is open, and air holes are formed on the cylinder 30, so that the inside and outside of the cylinder 30 are connected. The cylinder 30 can protect the liquid feeding bottle 40 and the liquid receiving bottle 50 on the one hand, and on the other hand, it is convenient for the operator to hold the entire flusher during operation.

[0053] A convex edge 14 extending downward is formed on the lower side of the cover body 11 ; the opening of the upper end of the cylinder 30 is inserted on the outer periphery of the convex edge 14 and is clamped on the convex edge 14 .

[0054] A first clamp ring and a second clamp ring extending upward are formed on the bottom surface of the cylinder 30; the first clamp ring is used to clamp the lower end of the liquid-feeding bottle 40, and the second clamp ring is used to clamp the lower end of the liquid-receiving bottle 50. The first clamp ring and the second clamp ring are fixed at the lower end, and the third joint and the fourth joint are fixed at the upper end, so that the liquid-feeding bottle 40 and the liquid-receiving bottle 50 are firmly fixed, and even when there is a lot of liquid in them, the bottle bodies of the liquid-feeding bottle 40 and the liquid-receiving bottle 50 are placed horizontally for operation, and the bottle bodies will not be tilted due to gravity, causing the connection between the liquid-feeding bottle 40 and the liquid-receiving bottle 50 and the third joint and the fourth joint to become loose, leak or even disconnect.

[0055] The upper end surfaces of the first clamp ring and the second clamp ring are shaped as inclined guide surfaces to facilitate the insertion of the liquid feeding bottle 40 and the liquid receiving bottle 50 .

[0056] A silicone ring 25 is formed on the front side of the outer frame 21, and the silicone ring has a trumpet-shaped opening. The silicone ring 25 is used to facilitate the eye mask unit to fit the physiological curve around the eye. In addition, the elasticity of the silicone ring also provides the possibility for the flushing device to adjust the flushing angle appropriately during the flushing process. For example, when the left side is pressed down more and the right side is pressed down less, the direction of the nozzle will tilt from right to left.

[0057] A groove 21 a recessed toward the rear side is formed at the front end of the outer frame 21 , and a rear end 25 a of the silicone ring 25 is retained in the groove 21 a .

[0058] The pushing device of the liquid-feeding bottle 40 comprises a piston 41 and a compression spring 42 . The compression spring 42 is arranged between the piston 41 and the bottom of the liquid-feeding bottle 40 . An air hole 43 is formed on the bottom of the liquid-feeding bottle 40 .

[0059] The mouth of the liquid-feeding bottle 40 is sealed by a first rubber stopper 44 ; the first rubber stopper 44 is fixed to the convex edge of the mouth of the liquid-feeding bottle 40 by an aluminum metal ring 45 .

[0060] The mouth of the liquid collecting bottle 50 is sealed by a second rubber stopper 51 ; the second rubber stopper 51 is fixed to the convex edge of the mouth of the liquid collecting bottle 50 through an aluminum metal ring 52 .

[0061] The outer frame 21 has a lower side formed with an insertion rod 26 extending downward.

[0062] The upper side of the cover body 11 is formed with an insertion rod and insertion tube 13 extending upward; the insertion rod 26 is tightly inserted into the insertion rod and insertion tube 13 .

[0063] The positions of the first joint 12a, the second joint 12b, and the insertion rod and the insertion tube 13 on the cover plate body 11 form an isosceles triangle, wherein the insertion rod and the insertion tube 13 are located at the vertices of the isosceles triangle. The arrangement at the triangle makes the eye mask unit more stably combined with the cover plate unit, so that the eye mask unit is closely attached to the eye.

[0064] The cross section of the insertion rod 26 is rectangular; the cross section of the inner cavity of the insertion rod cannula 13 is also a corresponding rectangle.

[0065] When in use, the rotating shaft is first rotated to close the first and second passages, the third joint is pierced through the rubber stopper of the liquid delivery bottle, and the fourth joint is pierced through the rubber stopper of the liquid collection bottle; then, after the person to be rinsed bends over, the operator's first hand holds the cylinder body and covers the eye to be rinsed with the eye mask unit, so that the skin around the eye is tightly overlapped with the silicone ring to prevent water leakage; the operator's second hand rotates the rotating shaft to open the first and second passages at the same time; the physiological saline in the liquid delivery bottle is pushed by the spring and the piston to be delivered to the eye mask unit through the first passage. The waste water is drawn into the inner tube and then sprayed out through the nozzle at the front end of the inner tube to rinse the eyeball; after the second hand of the operator completes the rotation of the rotating shaft, the thumb and index finger are respectively inserted into the upper finger tube and the lower finger tube, and the eyelids of the washed eye are opened with the fingers through the upper finger tube and the lower finger tube; the waste water after washing is guided to the inner frame by the sheet-like film and flows into the outer tube through the gap between the inner tube and the outer tube, and finally sucked into the liquid collecting bottle through the second passage; because the waste liquid is sucked by the liquid collecting bottle with negative pressure, the waste liquid can be quickly discharged and no water will accumulate in the eye mask unit. After washing, the fingers of the second hand are taken out from the upper finger tube and the lower finger tube, and the rotating shaft is rotated with the second hand to close the first and second passages. The operator and the person to be washed can be the same person.

[0066] In the present application, the eye mask unit, the cover unit, the liquid feeding bottle, and the liquid collecting bottle are all independent and replaceable individual components, which are easy to replace. The capacity of the liquid feeding bottle and the liquid collecting bottle is selected according to actual needs, for example, each can be 100 ml, so that the volume of the entire device is small.
