The eye is the most important organ in human sense, and about 80% of the knowledge in the brain is acquired by the eye. The eyes are needed to read the books and recognize words, watch pictures, watch figures, enjoy beautiful scenery and the like. The eye can distinguish light rays with different colors and brightness, and convert the information into nerve signals to be transmitted to the brain.

At present, for some office workers, the office workers often work overnight, so that eyes are in a fatigue state for a long time; at present, due to popularization of mobile phones, people often spend a great deal of time on the mobile phones to collect various information through the mobile phones, and the health of eyes is greatly influenced after the mobile phones are used for a long time; teenagers often read books under dim light, under the sun or on buses due to high learning pressure, and thus, the teenagers can cause great damage to eyes and cause the eyes to be short-sighted; in addition, many people suffer from ophthalmic diseases, and the eyes are often uncomfortable and require frequent washing.

At present, a cleaning cup is usually used for cleaning eyes, when the cleaning cup is used, a head is firstly lowered to slightly press the cleaning cup filled with cleaning liquid on the eyes, then the head is lifted up to fully soak the eyes in the cleaning liquid, then the cleaning liquid flows back and forth at the eyes by shaking the head and the eyes to clean, the head needs to be shaken continuously in the cleaning process, neck fatigue is easily caused, shaking is stopped, the cleaning liquid is in a static state, and the cleaning effect is not ideal; in addition, in the cleaning process, if the cleaning cup is removed carelessly, the cleaning liquid in the cleaning cup can be spilled out to wet clothes, so that the design of the eye washing device which can clean without sliding the head and does not need worry about the spilling of the cleaning liquid is very necessary.

As shown in fig. 16, the input pipe 7 and the output pipe 5 are provided with filter columns for filtering the cleaning solution flowing through the input pipe 7 and the output pipe 5.

The specific working process is as follows: when the device designed by the invention is used, firstly, the piston mechanism 3 is pulled away from the first cleaning solution storage shell 2, namely, the piston shell is pulled, so that the piston shell is far away from the first cleaning solution storage shell 2, when the piston shell moves to the side far away from the first cleaning solution storage shell 2, the fifth spring 48 arranged between the piston shell and the inner end surface of the nesting groove 58 of the first cleaning solution storage shell is stretched, meanwhile, the mounting plate 55 slides to the side far away from the piston disc 51 in the piston shell under the action of the pull rod 49, because a channel between the drainage pipe 20 and the cleaning cup 1 is closed when the device is not in operation, air in a space between the lower side of the piston disc 51 and the lower end surface of the piston shell is sealed, if the piston disc 51 moves the lower side of the piston disc 51, vacuum is generated, and then great resistance is provided, so that the piston disc 51 basically cannot move; the mounting plate 55 is now displaced relative to the piston disc 51 to stretch the fourth spring 50 so that the fourth spring 50 is urged upwards and the first washing liquid storage casing 2 and the piston casing are held relatively stationary by the spacing mechanism 46 with the fourth spring 50 being in a stretched condition.

The cleaning cup 1 is taken up and placed on the eye, so that the rubber pad 9 arranged on the cleaning cup 1 is in contact with the outer ring of the eye, then the cleaning cup 1 is pressed, the rubber pad 9 on the cleaning cup 1 is pressed to move towards the inside of the cleaning cup 1, the rubber pad 9 moves to drive the transmission rod 10 connected with the transmission rod to move, and the transmission rod 10 moves to drive the mounting shell 36 to move. The mounting shell 36 moves to drive the square block 33 mounted on the inner side of the mounting shell 36 to move, the square block 33 moves to drive the elastic shifting piece 34 to move, and meanwhile, the second spring 23 compresses; in the moving process of the elastic shifting piece 34, after the elastic shifting piece 34 is contacted with the driving block 32 arranged on the first rack, the driving block 32 extrudes the elastic shifting piece 34, so that the elastic shifting piece 34 is tightly attached to the side surface of the mounting shell 36, and after the elastic shifting piece 34 passes over the driving block 32 in the moving process, the elastic shifting piece 34 can be unfolded again under the action of self elasticity, so that one end of the elastic shifting piece 34, which is far away from the square block 33, is contacted with the driving block 32; then, the first cleaning liquid storage shell 2 and the second cleaning liquid storage shell 4 are vertically lifted, the first cleaning liquid storage shell 2 is located at a position higher than the cleaning cup 1, and the second cleaning liquid storage shell 4 is located lower than the cleaning cup 1, so that the cleaning liquid in the first cleaning liquid storage shell 2 flows through the cleaning cup 1 to the second cleaning liquid storage shell 4; the eye is cleansed by the flow of cleansing fluid.

In the using process, if people carelessly remove the cleaning cup 1 from the eye, a gap is formed between the cleaning cup 1 and the eye, and the rubber pad 9 loses the extrusion force applied by the eye to the cleaning cup, so the rubber pad 9 resets under the self elastic action, the rubber pad 9 resets to pull the transmission rod 10 to move, the transmission rod 10 moves to drive the installation shell 36 to move, the installation shell 36 moves to drive the square block 33 to move, the square block 33 moves to drive the elastic poking sheet 34 to move, the elastic poking sheet 34 moves to drive the driving block 32 in contact with the elastic poking sheet to move, the driving block 32 moves to drive the first rack to move, the first rack moves to drive the gear 19 to rotate, the gear 19 rotates to drive the second rack 18 to move to one side close to the liquid discharge pipe 20, the second rack 18 moves to drive the conical switch 41 installed in the liquid discharge pipe 20 to move to one side far away from the conical end, so that a gap is formed between the outer circumferential surface of the taper switch 41 installed in the discharge pipe 20 and the inner circumferential surface of the taper end of the discharge pipe 20, the passage between the discharge pipe 20 and the washing cup 1 is opened, and at the same time, the third spring 40 installed in the discharge pipe 20 is compressed; when the passage between the drainage pipe 20 and the cleaning cup 1 is opened, the piston disc 51 moves upwards under the pulling force of the fourth spring 50, the piston disc 51 moves upwards to generate negative pressure in the space below the piston disc 51 in the piston shell, and under the negative pressure, the cleaning liquid in the cleaning cup 1 is absorbed and collected in the piston shell.
