Description

Technical Field

[0001] This invention relates to the field of eyewash technology, and particularly to a portable eyewash device. Background Technology

[0002] An eyewash station is an emergency rescue device. During experiments, it is inevitable that test reagents will splash into the eyes. When reagents get into the eyes, it is necessary to rinse the eyes with clean water or cleaning solution in time to reduce the damage caused by the reagents. Existing portable eyewash stations generally consist of a base, a clean water tank, and an eyewash nozzle. By bringing the eyes close to the eyewash nozzle, clean water from the tank is sprayed out through the eyewash nozzle to rinse the eyes.

[0003] According to application number CN202310071109.3, a hand-push portable eyewash station is disclosed. The eyewash station includes a base, an eyewash stand, and two sets of pressure-activated eyewash nozzles. The base includes a wastewater tank with several wheels fixed to its bottom and an eyewash platform fixed to its top. An eyewash stand mounting groove is formed in the middle of the eyewash platform. The eyewash stand includes a clean water tank, which is inserted and installed in the eyewash stand mounting groove of the eyewash platform. The key feature is that a partition is inserted and fixed inside the wastewater tank, dividing the inner cavity of the wastewater tank into a front wastewater chamber and a rear equipment chamber. A pneumatic pump, an air tank, and a solenoid valve are inserted and fixed inside the rear equipment chamber of the wastewater tank. The pneumatic pump, air tank, and solenoid valve are connected in series on an air supply pipeline, the end of which is fixed to the eyewash platform. This eyewash station improves the eyewash effect by injecting air into the clean water tank, which forces water out of the tank through air pressure to form a water jet.

[0004] However, existing portable eyewash stations have limitations during use. Because they are placed in a fixed location, when harmful substances splash into the eyes, the eyes will produce a lot of tears after feeling pain, which will cause blurred vision and make it difficult to find the eyewash station in time. This can delay the best time to clean the eyes. In addition, when rinsing the eyes, if the water jet is too strong, it can cause discomfort to the user and affect the use of the device.

Beneficial effects

[0016] This invention achieves eye cleaning through its cleaning mechanism. The cleaning cup is placed against the outside of the eye via a rubber ring. By rotating the operating component, the driving bevel gear drives the driven bevel gear to rotate. The rotation of the driven bevel gear causes the cleaning tank to align with the connecting tank, thus connecting the inside of the cleaning bottle to the outside. The piston then slides upward under the action of the compression spring, squeezing the cleaning solution inside the cleaning bottle. The cleaning solution is then sprayed out through the cleaning head to clean the eyes. It is convenient to use and carry, allowing the eyewash station to be removed and used to clean the eyes in a short time, ensuring the user's health. Furthermore, the one-way damper reduces the sliding speed of the piston, preventing excessive water flow impact from the cleaning head, thus improving the user experience and practicality.

[0017] In addition, the adsorption mechanism enables the adsorption of overflowing cleaning fluid. When the cleaning fluid overflows through the outside of the rubber ring, it flows downwards. When the outflowing cleaning fluid comes into contact with the absorbent cotton, the absorbent cotton will absorb the cleaning fluid, preventing the cleaning fluid from flowing out and falling onto the instruments in the laboratory and causing contamination. This ensures the cleanliness of the surrounding environment, guarantees the normal use of the instruments, and reduces economic losses.

[0018] In addition, the recycling mechanism enables the recycling of eyewash solution. After rinsing the eyes with the cleaning head, the solution flows into a recycling bag through a connecting tube to collect the used solution, preventing it from leaking out and polluting the surrounding environment, and ensuring the cleanliness of the laboratory.

[0019] Furthermore, the aforementioned mechanisms enable eye cleaning, ensuring user health, improving user experience, and enhancing practicality. They also facilitate the absorption of spilled cleaning fluid, maintaining a clean environment, ensuring normal instrument operation, reducing economic losses, and enabling the recycling of eye cleaning fluid, thus ensuring a clean laboratory.

The following components are installed on the outer side of the sliding plate 6: a compression spring 9 is fixedly connected to the inner side of the lower end of the cleaning bottle 1, and the upper end of the compression spring 9 is fixedly connected to the lower end face of the sliding plate 6; a one-way damper 10 is fixedly installed on the inner side of the fixed plate 8; a fixed roller 11 is fixedly connected to the outer side of the rotating shaft of the one-way damper 10; the lower end of the connecting rope 12 is wound around the outer side of the fixed roller 11, and the upper end of the connecting rope 12 is fixedly connected to the lower end face of the sliding plate 6; a fixed frame 13 is fixedly connected to the outer side of the fixed plate 8; and a spiral spring 14 is fixedly connected to the inner side of the fixed plate 8. The outer ring of the spiral spring 14 is fixedly connected to the outer side of the fixing frame 13 on the outside of the rotating shaft of the damper 10; two pressing blocks 15 are provided, and both pressing blocks 15 are slidably connected to the outside of the cleaning bottle 1; two limiting blocks 16 are provided, and the two limiting blocks 16 are respectively fixedly connected to the inner side of the two pressing blocks 15, and both limiting blocks 16 are slidably connected to the inner side of the cleaning bottle 1; a baffle 17 is fixedly connected to the inner side of the cleaning cover 2; two cleaning grooves 1701 are provided, and both cleaning grooves 1701 are opened on the baffle. The inner side of plate 17; driven bevel gear 18 is rotatably connected to the lower end face of baffle 17; two connecting grooves 1801 are provided, both of which are opened on the inner side of driven bevel gear 18; operating member 19 is rotatably connected to the outer side of cleaning cover 2; limiting block 1901 is fixedly connected to the inner side of operating member 19, and limiting block 1901 is slidably connected to the inner side of limiting groove 201; driving bevel gear 20 is fixedly connected to the inner side of operating member 19, and driving bevel gear 20 meshes with driven bevel gear 18.

[0036] The specific usage and function of this embodiment are as follows: When it is necessary to clean the eyes, place the cleaning cup 4 against the outside of the eyes. At this time, the rubber ring 5 will contact the skin to prevent the liquid from flowing out during the cleaning process. After placing the cleaning cup 4 against the outside of the eyes, rotate the operating component 19. The rotation of the operating component 19 drives the driven bevel gear 18 to rotate through the driving bevel gear 20. This causes the connecting groove 1801 on the inner side of the driven bevel gear 18 to coincide with the cleaning groove 1701 on the inner side of the baffle 17. At this time, the sliding plate 6 and the piston component 7 inside the cleaning bottle 1 will slide upward under the action of the compression spring 9, squeezing the liquid in the cleaning bottle 1 and spraying the liquid in the cleaning bottle 1 through the cleaning head 3 to clean the eyes. When the sliding plate 6 slides, it pulls the connecting rope 12, and the connecting rope 12 is pulled. The movement causes the fixed roller 11 to rotate, unwinding the connecting rope 12. During the rotation of the fixed roller 11, the rotation speed is slowed down by the one-way damper 10, allowing the piston 7 to slide at a uniform speed and squeeze the liquid in the cleaning bottle 1. At this time, the liquid in the cleaning bottle 1 will be sprayed out through the cleaning head 3 in a smooth state to clean the eyes. When filling is required, the cleaning cap 2 is unscrewed, and the piston 7 can be pressed down with the long rod, so that the sliding plate 6 slides to the lower end of the cleaning bottle 1. At this time, the pressing block 15 is pinched, so that the limiting block 16 is inserted into the inner side of the limiting groove 601 to limit the sliding plate 6. At this time, the liquid for cleaning the eyes can be injected into the cleaning bottle 1. At the same time, when the limiting block 16 slides down, the fixed roller 11 will wind up the connecting rope 12 under the action of the spiral spring 14. Example

[0037] Based on Example 1, such as Figure 8 As shown, it also includes an adsorption mechanism, a fixing block 21, a right-angle rod 22, a hinge plate 23, an arc-shaped groove 2301, absorbent cotton 24, a torsion spring 25, and a fixing shaft 26; the adsorption mechanism is located on the outside of the cleaning cup 4; the fixing block 21 is fixedly connected to the outside of the cleaning cup 4; the right-angle rod 22 is hinged to the inside of the fixing block 21; the hinge plate 23 is hinged to the upper end of the right-angle rod 22, and the upper end surface of the hinge plate 23 is provided with Velcro; there are two arc-shaped grooves 2301, both of which are opened at the lower end of the hinge plate 23; the absorbent cotton 24 is attached to the upper end surface of the hinge plate 23 by Velcro; there are two torsion springs 25, both of which are fixedly connected to the outside of the fixing block 21, and both of which are fixedly connected to the outside of the lower end pivot of the right-angle rod 22; there are two fixing shafts 26, both of which are fixedly connected to the outside of the upper end of the right-angle rod 22.

[0038] The specific usage and function of this embodiment are as follows: When the cleaning cup 4 is placed against the outside of the eye, the absorbent cotton 24 will be pressed against the outside of the skin by the right-angle rod 22 under the action of the torsion spring 25. During the cleaning process of the eye, if liquid flows out, the liquid will be absorbed by the absorbent cotton 24. After use, since the absorbent cotton 24 is attached to the outside of the hinge plate 23 by Velcro, the absorbent cotton 24 can be removed and replaced with a new absorbent cotton 24. Example

[0039] Based on Example 1, such as Figure 1 As shown, it also includes a recycling mechanism, a recycling bag 27, a fixing bracket 28, a fixing cap 29, and a connecting hose 30; the recycling mechanism is located on the outside of the cleaning bottle 1; the recycling bag 27 is attached to the outside of the cleaning bottle 1 by Velcro; the fixing bracket 28 is fixedly connected to the outside of the cleaning bottle 1; the fixing cap 29 is fixedly connected to the inside of the fixing bracket 28, and the fixing cap 29 is threadedly connected to the recycling bag 27; the connecting hose 30 is fixedly connected to the upper end of the fixing cap 29, and the upper end of the connecting hose 30 is fixedly connected to the outside of the cleaning cup 4, and the connecting hose 30 connects the recycling bag 27 and the cleaning cup 4.

[0040] The specific usage and function of this embodiment are as follows: During the eye cleaning process, the cleaning liquid will fall into the cleaning cup 4, and the cleaning liquid in the cleaning cup 4 will flow into the recycling bag 27 through the connecting hose 30 for recycling.
