Referring to fig. 1 and 8, the adjusting mechanism 4 includes: the eye opening mechanism comprises a first limiting rotating shaft 41 arranged in the middle, three adjusting rods 42 of different sizes arranged on the first limiting rotating shaft 41 and a seal box 43 arranged outside the whole adjusting mechanism 4 and used for preventing the adjusting mechanism 4 from being damaged, wherein an adjusting knob 44 is arranged on the outer side of the seal box 4, the adjusting knob 44 is fixedly connected with the first limiting rotating shaft 41, so that the adjusting knob is rotated to drive the first limiting rotating shaft to rotate, the opening angle of the opening mechanism is adjusted, the rotating angle of the first limiting rotating shaft is adjusted, the side face of the seal box 43 is an organ-shaped box body made of rubber, the adjusting rods 42 of three different sizes can complete three different opening states of the eye part by the opening mechanism 2, the opening head 23 is made of silica gel, and a protective pad 231 arranged on the opening head is a softer thin silica gel sleeve.

With continued reference to fig. 2, the wash bottle 3 includes: a liquid outlet 31 arranged at one end of the cleaning bottle 3 close to the eye part, a liquid inlet 32 arranged at the other end of the cleaning bottle, and a liquid storage chamber 35 communicated with the liquid outlet 31 and the liquid inlet 32, wherein a spiral pipe 33 is arranged between the liquid storage chamber 35 and the liquid outlet 31 to reduce the liquid pressure, an electromagnetic valve is arranged at one end of the liquid outlet 31 to adjust the water output of the liquid outlet, and the liquid inlet 32 is connected with an external liquid inlet device; this embodiment does not do the restriction to external inlet means's structure, and it should be understood by those skilled in the art that, external inlet means only need can to wash in the bottle 3 last supply liquid can, it can be a small-size liquid pump, only need provide have less flow the washing liquid can, the during operation, the washing liquid passes through external inlet means gets into stock solution chamber 35, the washing liquid by under small-size liquid pump the stock solution chamber extrudees extremely in the spiral pipe 33, the warp spiral pipe 33 reachs liquid outlet 31.

Specifically, the use method of the invention comprises the following steps:

when the device is used for cleaning the eyes of a patient, firstly, the hand-held block 11 is clamped by fingers, the two opening heads 23 are respectively aligned to the upper and lower eyelids, the adjusting knob 44 is rotated to enable the adjusting rod 42 to jack up the fixing plate 25, so that the first opening arm 21 and the second opening arm 22 are opened, the opening step of the eyes is completed, the angle between the liquid outlet 31 and the eyes is adjusted through the second limiting rotating shaft 5 below the hand-held block 11, the distance between the liquid outlet 31 and the eyes is adjusted through the slide way 12, the patient information is input through clicking the touch display screen to control the invention to start to spray cleaning liquid to complete the cleaning of the eyes, in the cleaning process, the water flow size during the eye cleaning process is adjusted in real time according to the adjusting standard in combination with the contour size of the eyes of the patient and the current cleaning position, the stability of the flow size in the cleaning process is ensured, and the eye damage caused by the overlarge water flow is, guarantee to wash the effect stable, and the washing liquid can flow out eyes along the canthus to collect the waste liquid through collecting vat 232.

So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
