[0024] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a portable eyewash device of the utility model in conjunction with the accompanying drawings.

[0025] like Figures 1 to 5 As shown, a portable eyewash of the utility model comprises a liquid storage tank 1, on which a filling port and a discharge port 6 are provided, and a blocking cover is detachably connected to the filling port, and the blocking cover can prevent dust or other impurities from entering the liquid storage tank 1. At the same time, a cleaning component for cleaning the eyes is rotatably provided on the side wall of the liquid storage tank 1, and the cleaning component is connected to the discharge port 6 through a connecting pipe. A locking portion 7 for limiting the cleaning component is also provided on the liquid storage tank 1. Through the locking portion 7, the user can open and close the cleaning component from the liquid storage tank 1 more labor-saving and quickly, so that the injured part of the user can be cleaned in time, and the injured part of the user can be prevented from further deteriorating due to the inability to open the cleaning component. The cleaning component includes a hand buckle frame 3 rotatably arranged on the side wall of the liquid storage tank 1, and a liquid outlet channel 4 is arranged on the hand buckle frame 3. The liquid outlet channel 4 is U-shaped, and a connector 5 is connected to the liquid outlet channel 4 near the discharge port 6 of the liquid storage tank 1. The connector 5 and the discharge port 6 are connected through a connecting pipe, and a liquid outlet 41 is opened at one end of the liquid outlet channel 4 relative to the connector 5, that is, there are two liquid outlets 41 of the liquid outlet channel 4, and the distance between the two liquid outlets 41 is adapted to the distance between the two eyes of the human body, so as to clean the user's eyes after the liquid outlet 41 discharges water. The connecting pipe is detachable between the connecting pipe 5 and the discharge port 6, so that after the connecting pipe is used for a long time, it can be disassembled to clean its inside or directly replaced.

[0026] When cleaning the eyes, the top of the hand buckle frame 3 can be directly pulled outward, and after the locking portion 7 releases the limit of the hand buckle frame 3, the hand buckle frame 3 will be fully opened due to its own weight. Figure 2 As shown, the hand buckle frame 3 is in the open state. At this time, the two liquid outlets 41 of the liquid outlet channel 4 are lower than the bottom surface of the liquid storage tank 1. Under the pressure of the liquid in the liquid storage tank 1, the liquid will be sprayed out through the liquid outlets 41. At this time, the user can bend down and align the eyes and get close to the liquid outlets 41.

[0027] In order to facilitate the storage of the hand buckle frame 3, a placement groove 2 adapted to the hand buckle frame 3 is opened on the side wall of the liquid storage tank 1, and a groove 101 for installing the locking part 7 is provided in the placement groove 2. Figure 2 and Figure 3 As shown, the locking part 7 for limiting the handcuff frame 3 includes a shell 71 arranged on the side wall of the liquid storage tank 1, a slide groove 72 is opened in the shell 71, and a slider 73 is slidably arranged in the slide groove 72, a locking block 74 is arranged at the outer end of the slider 73, and a spring 75 is arranged between the inner end of the slider 73 and the slide groove 72. At the same time, in order to prevent the elastic force of the spring 75 from pushing the locking block 74 out of the slide groove 72 through the slider 73, a limiting frame 76 is arranged at the open end of the shell 71, and the locking block 74 can slide in the limiting frame 76. It should be noted that the head of the locking block 74 is chamfered, so that the handcuff frame 3 can be pulled out and closed from the placement slot 2 more smoothly. Specifically, when the hand buckle frame 3 is pulled out from the placement slot 2, the edge of the hand buckle frame 3 will directly compress the lock block 74 through the chamfer of the lock block 74, so that the lock block 74 starts to compress the spring 75 through the slider 73, and after the lock block 74 slides into the housing 71 to release the limit of the hand buckle frame 3, the hand buckle frame 3 can be fully opened. When the hand buckle frame 3 is no longer in contact with the lock block 74, the spring 75 will push the lock block 74 outward through the slider 73 and push the lock block 74 to the initial position. When the locking portion 75 is needed to limit the hand buckle frame 3 again, the hand buckle frame 3 is lifted and pressed toward the limiting portion, and the hand buckle frame 3 will contact and press with the chamfer of the outer side surface of the locking block 74 again, and then the locking block 74 moves into the shell 71 through the slider 73 and compresses the spring 75, thereby releasing the limit of the hand buckle frame 3 by the locking block 74, allowing the hand buckle frame 3 to completely enter the placement slot 2. At this time, the hand buckle frame 3 is not in contact with the locking block 74, and the spring 75 will push the locking block 74 toward the initial position through the slider 73, completing the limiting work of the hand buckle frame 3 by the locking block 74, which is convenient and labor-saving to use.

[0028] As a further improvement, connecting arms 8 are provided at the upper and lower ends of the outer shell 71 of the locking portion 7, and through holes 9 are provided on the connecting arms 8, and screws 10 can be inserted into the through holes 9. The locking portion 7 can be fixed on the liquid storage tank 1 by the screws 10. At the same time, when the locking portion 7 needs to be replaced, the screws 10 on it can also be unscrewed and replaced.

[0029] Preferably, the liquid outlet channel 4 is provided with an installation cavity 11 at the position of the liquid outlet 41, and a nozzle 12 is detachably provided in the installation cavity 11. The nozzle 12 can filter impurities in the liquid storage tank 1. At the same time, the impurities in the nozzle 12 and the installation cavity 11 can also be cleaned in time to keep the cleaning liquid flowing out smoothly from the nozzle 12. Specifically, the nozzle 12 includes a limit frame 124 detachable in the installation cavity 11, and a threaded hole 125 is provided on the limit frame 124, and a bolt 126 is threadedly connected in the threaded hole 125. A nozzle 121 is penetrated on the bolt 126, and the nozzle 121 is located outside the liquid outlet 41, and the circumferential size of the nozzle 121 is larger than the inner diameter of the liquid outlet 41, so that the liquid outlet 41 is located between the nozzle 121 and the limit frame 124, and when the bolt 126 tightens the nozzle 121 and the limit frame 124, the nozzle 121 and the limit frame 124 will be fixed on the liquid outlet 41. Specifically, an extension ring 122 is provided at the bottom end of the nozzle 121, and the outer diameter of the extension ring 122 is less than or equal to the diameter of the liquid outlet 41. A sealing ring 123 is sleeved outside the extension ring 122 to seal the liquid outlet 41, and the outer diameter of the sealing ring 123 is greater than the outer diameter of the liquid outlet 41. The limiting frame 124 includes a limiting column 1241 that can be detached from the installation cavity 11, and the threaded hole 125 is provided on the limiting column 1241. At the same time, support arms 1242 are evenly distributed around the limiting column 1241. When installing the nozzle 12, the sealing ring 123 can be sleeved on the extension ring 122, and then the nozzle 121 and the limiting frame 124 are connected by the bolt 126, and the gap between the nozzle 121 and the limiting frame 124 is made larger than the wall thickness between the outer wall of the liquid outlet 41 and the installation cavity 11, and then the support arms 1242 of the limiting frame 124 are respectively inserted into the installation cavity 11, and then the nozzle 121 is lifted up, and the nozzle 121 drives the top surface of the support arm 1242 on the limiting frame 124 to fit with the top surface of the installation cavity 11 through the bolt 126, and then the bolt 126 is tightened to complete the installation of the nozzle 12 on the liquid outlet 41. Specifically, in this embodiment, the support arms 1242 are preferably three, and the maximum outer diameter formed by the free ends of the three support arms 1242 is larger than the inner diameter of the liquid outlet 41, so that the limiting frame 124 can be limited in the installation cavity 11. However, the maximum outer diameter of the free ends of the three arms 1242 must satisfy the condition that they can be freely disassembled and assembled from the installation cavity 11.

[0030] like Figure 4 and Figure 5As shown, a limit plate 13 is also provided on the bottom surface of the extension ring 122, and the limit plate 13 cooperates with the limit column 1241. After the nozzle 12 is installed in the installation cavity 11, the limit plate 13 will be inserted into one side of the adjacent support arm 1242. When the bolt 126 is rotated, the limit frame 124 threadedly connected to the bolt 126 may also rotate. When the support arm 1242 contacts the limit plate 13, the support arm 1242 will limit the limit frame 124, preventing the limit frame 124 from continuing to rotate with the bolt 126. At the same time, in order to increase the connection strength between the support arm 1242 and the limit column 1241 on the limit frame 124, a reinforcing plate 14 is provided between the support arm 1242 and the limit column 1241.

[0031] Instructions for use: Place the portable eyewash station in an appropriate position, and add an appropriate amount of cleaning liquid into the liquid storage tank 1 through the filling port. When the user uses it, he only needs to pull the hand buckle frame 3 outward through the top of the hand buckle frame 3, and when the hand buckle frame 3 is pulled outward, the locking block 74 on the locking portion 7 will be compressed, so that the locking block 74 releases the limiting work of the hand buckle frame 3, and then the hand buckle frame 3 can be fully opened. After the hand buckle frame 3 is opened, because the liquid outlet 41 is lower than the bottom of the liquid storage tank 1, the cleaning liquid in the liquid storage tank 1 is sprayed out through the liquid outlet channel 4 and the nozzle 12 on the liquid outlet 41, and then the user bends down and aligns the eyes with the liquid outlet 41 to complete the purpose of eye cleaning. When the hand buckle frame 3 needs to be recovered to the initial position, the hand buckle frame 3 is lifted and pressed toward the placement slot 2, and the hand buckle frame 3 presses the locking block 74 on the locking portion 7 again, so that the locking block 74 releases the limit on the movement of the hand buckle frame 3 into the placement slot 2. After the hand buckle frame 3 completely enters the placement slot 2, the locking block 74 that has restored the initial position will limit the position of the hand buckle frame 3.
