[0042] Further, in the embodiment, the raised end of the spray base 1 is provided with an anti-theft ring 6 between the spray knob 2, through the setting of the anti-theft ring 6, it can avoid the situation of spraying water due to external force in the abnormal use state such as production or transportation, so as to cause the waste of product, at the same time, the anti-theft ring 6 also makes the whole structure more reasonable.

[0043] Further, in the embodiment, the eye washing cup 3 is made of silica gel material, and a bottom hole 301 is formed in the bottom of the eye washing cup 3, the other end of the spray knob 2 is sleeved outside the eye washing cup 3, and the other end of the connecting pipe 201 passes through the bottom hole 301 and is located inside the eye washing cup 3.

[0044] The other end of the spray knob 2 is rotatably connected with the eye washing cup 3, through the rotary connection, the position of the eye washing cup 3 can be kept unchanged, through rotating the spray knob 2 or the bottle body 5, the relative rotation between the spray knob 2 and the spray base 1 occurs, the bottle body 5 rises or falls under the action of the sliding block 203 and the track groove 101, so that the suction pipe 502 is pressed down by the connecting pipe 201, and the suction pipe 502 performs water pumping and spraying.

[0045] Further, in the embodiment, the atomizing sheet 4 is fixedly installed at one end of the connecting pipe 201 located inside the eye washing cup 3, the atomizing sheet 4 includes a cylinder 401 with one end open, the cylinder 401 is fixedly installed in the connecting pipe 201, a bottom center of the cylinder 401 is provided with an atomizing hole 403, an outer circle of the atomizing hole 403 is provided with a flow guide block 402, and the flow guide block 402 is fixedly installed at the bottom of the cylinder 401; after water enters the atomizing sheet 4 from the connecting pipe 201, the water forms a counter-rotating flow under the action of the flow guide block 402, and then is discharged through the atomizing hole 403, so that the water forms a diffused atomized water mist.

[0046] The flow guide block 402 is provided with two blocks, and the whole is in an arc shape and is centrally symmetric about the atomizing hole 403, the two flow guide blocks 402 correspond to each other at the head and tail, and two flow guide gaps 404 are arranged between the head and the tail, the two flow guide gaps 404 form a counter-rotating structure, and the water forms a rotating flow through the flow guide gaps 404.

[0047] The cover plate 406 is fixedly connected to one side of the flow guide block 402, and the cover plate 406 and the flow guide block 402 form a water inlet groove 405 with the cylinder 401, and the water inlet groove 405 is in communication with the flow guide gap 404. By fixing the cylinder 401 in the connecting pipe 201, water first enters the water inlet groove 405 in the connecting pipe 201, and then enters the atomizing hole 403 through the two flow guide gaps 404 on the side. Since the two flow guide gaps 404 are in a butt structure, the water can form a rotational flow and then be discharged from the atomizing hole 403, so that after being discharged from the atomizing hole 403, the water forms a diffused atomized water mist.

[0048] It should be noted that the amount of water rotation can be adjusted by changing the distance of the flow guide gap 404, thereby adjusting the atomization amount to adapt to different situations. Moreover, the conventional atomizing sheet generally has a plurality of atomizing small hole structures, which divides water to form atomization. However, the atomizing sheet 4 of the present application has only one hole, and the atomizing diffusion range of water of the atomizing sheet 4 is larger than that of the conventional atomizing sheet. Therefore, the conventional atomizing sheet is easy to form a water column, which can cause eye discomfort, and the atomizing diffusion range is also relatively small.

[0049] Specifically, in use, the user rotates the spray knob 2 or the bottle body 5 to make the spray knob 2 relatively rotate with the spray base 1 fixed to the bottle mouth. The sliding block 203 on the inner wall of the spray knob 2 moves along the spiral track groove 101 on the spray base 1 to convert the rotary motion into the downward pressure of the spray knob 2. The downwardly pressed spray knob 2 presses the connecting pipe 201 in the interior thereof to press the suction pipe 502, so that the elastic water pump 501 at the top end of the bottle body generates negative pressure to suck the water in the bottle up through the suction pipe 502. The sucked water enters the connecting pipe 201 through the through hole 102 and is delivered to the atomizing sheet 4 fixed to the end of the connecting pipe. The water flow is guided to form a butt rotational flow through the flow guide gap 404 formed by the flow guide block 402 in the interior of the atomizing sheet, and finally is sprayed out from the single atomizing hole 403 to form a soft atomized water mist with a wide diffusion range, which is used for the user to clean the eyes. Embodiment 2:

[0050] Please refer to Figures 1-6 On the basis of the above-mentioned embodiments, a plurality of continuous and spiral track grooves 101 are formed on the outer wall of the protruding end of the spray base 1, and the plurality of track grooves 101 are in communication through the vertical transition grooves between the first and last ends. When the sliding block 203 enters the transition groove, the elastic water pump 501 returns the connecting pipe 201 to the original position through the suction pipe 502 to realize multi-section continuous spraying.

[0051] 0Specifically, in use, the track groove 101 is arranged in the form of multiple connected tracks, for example, four track grooves 101 are arranged on the outer wall of the protruding end of the spray base 1, and the first track groove is connected to the last track groove through a transition groove in the vertical direction. Due to the resilience of the elastic water pump 501, when the sliding block 203 is in the track groove 101 and the suction pipe 502 is pressed down by the connecting pipe 201, the sliding block 203 enters the transition groove, and the elastic water pump 501 is used to lift the connecting pipe 201 back to the original position through the suction pipe 502, that is, the spray knob is reset, and continuous spraying of multiple sections can be achieved.

[0052] The scheme in this embodiment can be selectively combined with the schemes in other embodiments.

[0053] The working principle and specific use process of the eye washing device are as follows: When the eye washing device needs to be used, the user first tears off the anti-theft ring 6, normally rotates the spray after tearing off the anti-theft ring 6, and then holds the eye washing device and rotates the spray knob 2 or the bottle body 5. Relative rotation occurs between the spray knob 2 and the spray base 1 fixedly installed at the bottle mouth. At this time, the sliding block 203 arranged on the inner wall of the spray knob 2 will slide along the spiral track groove 101 opened on the outer wall of the protruding end of the spray base 1. The cooperation of the spiral groove and the sliding block accurately converts the rotating action of the user into the downward linear movement of the spray knob 2 relative to the spray base 1.

[0054] With the downward movement of the spray knob 2, the connecting pipe 201 fixedly arranged inside the spray knob 2 presses the suction pipe 502 extending into the through hole 102 of the spray base 1 downward. After being pressed, the suction pipe 502 compresses the elastic water pump 501 connected thereto, so that a negative pressure is generated in the elastic water pump 501. The negative pressure sucks the liquid in the bottle body 5 up through the suction pipe 502. The sucked liquid flows through the suction pipe 502, the through hole 102 of the spray base 1, and the connecting pipe 201 in the spray knob 2 in sequence, and is finally delivered to the atomizing sheet 4 fixedly installed at the end of the connecting pipe 201.

[0055] The atomizing sheet 4 is designed with a unique flow guide structure: the liquid first enters the water inlet groove 405 formed by the cylinder body 401, the flow guide block 402, and the cover plate 406, and then is forced to pass through the flow guide gap 404 between the two center-symmetric and arc-shaped flow guide blocks 402. The two flow guide gaps 404 constitute a hedging structure, so that the liquid forms a high-speed rotating vortex at this position. The rotational flow finally sprays out from the single atomizing hole 403 located at the center. Due to the combined action of centrifugal force and hedging, the liquid is fully broken, thereby forming a fine water mist with a large diffusion range and soft texture, which perfectly meets the comfort and safety requirements of eye cleaning.

[0056] In addition, by rotating the spray knob 2 to reset, under the resilience of the elastic water extractor 501, the device can be prepared for the next spray, and if the track groove 101 is designed as multiple sections, multiple continuous sprays can be achieved.

[0057] It should be noted that, although the above-mentioned embodiments have been described herein, the patent protection scope of the present application is not limited thereby. Therefore, based on the innovative idea of the present application, changes and modifications to the embodiments described herein, or equivalent structures, equivalent processes or equivalent function transformations made using the content of the present application specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the protection scope of the present application patent.
