Description

Technical Field

[0001] This utility model relates to the field of emergency safety protection equipment technology, specifically to a portable eyewash station. Background Technology

[0002] Eyewash stations are used to provide emergency rinsing of the eyes and face when workers' eyes or faces come into contact with toxic, harmful, or other corrosive chemicals. This prevents further harm and minimizes the damage. They are widely used in the petroleum, chemical, semiconductor, and pharmaceutical industries, as well as in locations where hazardous materials are exposed.

[0003] Existing eyewash stations are usually fixed to the wall and cannot be carried around. When using them, staff need to find the location of the eyewash station themselves, which can sometimes delay the best time for rescue. In addition, existing eyewash stations usually require a water pump and other structures to deliver the eyewash solution to the eyewash nozzles, which also makes the existing eyewash station structure relatively complex. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a portable eyewash station that overcomes these deficiencies. Its reasonable design allows for convenient and quick use in various locations. Furthermore, it relies entirely on the pressure of the liquid within the tank to achieve the desired eyewash effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A portable eyewash station includes a water tank with a water inlet at the top and a through mounting groove on the front side of the water tank. A water delivery frame is movably engaged in the mounting groove. Shaft holes are provided at the bottom of the two side walls of the mounting groove. Rotating shafts are fixedly installed at the bottom of the two side walls of the water delivery frame. The bottom of the water delivery frame is rotatably connected to the shaft holes at the bottom of the two side walls of the mounting groove via the rotating shafts.

[0007] Two eyewash nozzles are installed above the inner side of the water supply frame and the mounting groove. A U-shaped water channel is provided inside the water supply frame, and the upper end of the U-shaped water channel is connected to the two eyewash nozzles respectively. A water inlet connector is provided at the lower end of the U-shaped water channel. A water outlet connector is provided at the lower end of the front side of the water tank, and the water outlet connector is connected to the inner cavity of the water tank. The water outlet connector and the water inlet connector are connected to each other through a water pipe.

[0008] When the water supply frame is snapped into the installation slot, the height of the eyewash nozzle is higher than the height of the water tank.

[0009] Preferably, the two side walls of the mounting groove are provided with snap-fit ​​protrusions, and the two sides of the outer surface of the water conveying frame are provided with snap-fit ​​grooves, and the snap-fit ​​protrusions cooperate with the snap-fit ​​grooves.

[0010] Preferably, a support protrusion is provided on the lower outer side of the water conveying frame.

[0011] Preferably, a snap-fit ​​groove is provided in the middle of the lower end face of the water conveyor, and snap-fit ​​protrusions are provided on both sides of the snap-fit ​​groove, and the water pipe is movably snapped into the snap-fit ​​groove.

[0012] Preferably, pipe clamps are provided at both ends of the water pipe.

[0013] Preferably, the upper surface of the water tank is provided with a handle.

[0014] Preferably, the water inlet is connected to an outer cover by a thread, the outer cover has a locking ring on its side, and the water tank has a locking lug on its side, with the locking ring and the locking lug corresponding to each other.

[0015] Preferably, a sign is fixedly installed on the outer side of the water conveyor frame.

[0016] This invention provides a portable eyewash station. It offers the following advantages: Through the rotating connection between the water supply frame and the water tank, the frame can be rotated downwards to a horizontal position. At this point, the liquid pressure of the eyewash solution within the tank forces the solution to flow from the outlet connector along the water pipe into the U-shaped water channel, and then spray it outwards through two eyewash nozzles at the end of the U-shaped channel, directly cleaning the user's eyes. The entire device only requires the size of the water tank, making it easy to relocate and use quickly. Furthermore, the eyewash effect is achieved entirely by the pressure of the liquid within the tank. Therefore, the device does not require an additional water pump or other complex structure, nor does it need electrical connection, making it much simpler to use. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0025] Example 1, as Figure 1-4 As shown, a portable eyewash station includes a water tank 1 with a water inlet at the top and a vertically extending mounting groove 2 on the front side of the water tank 1. A water delivery frame 3 is movably engaged in the mounting groove 2. Shaft holes 19 are provided at the bottom of the two side walls of the mounting groove 2. Rotating shafts 20 are fixedly installed at the bottom of the two side walls of the water delivery frame 3. The bottom of the water delivery frame 3 is rotatably connected to the shaft holes 19 at the bottom of the two side walls of the mounting groove 2 via the rotating shafts 20.

[0026] Two eyewash nozzles 4 are installed above the inner side of the water supply frame 3, which is attached to the mounting groove 2. A U-shaped water channel 5 is installed inside the water supply frame 3, and the upper end of the U-shaped water channel 5 is connected to the two eyewash nozzles 4. A water inlet connector 6 is installed at the lower end of the U-shaped water channel 5. A water outlet connector 7 is installed at the lower end of the front side of the water tank 1, and the water outlet connector 7 is connected to the inner cavity of the water tank 1. The water outlet connector 7 and the water inlet connector 6 are connected to each other through a water pipe 8. When the water supply frame 3 is engaged in the mounting groove 2, the height of the eyewash nozzles 4 is higher than the height of the water tank 1.

[0027] Working principle:

[0028] Under normal conditions, the water supply frame 3 is snapped into place within the mounting groove 2. At this time, the two eyewash nozzles 4 on the water supply frame 3 are at a higher level than the water tank 1, preventing liquid from flowing out of the eyewash nozzles 4. When needed, the entire water tank 1 can be moved to a suitable position. The water supply frame 3 is moved out of the mounting groove 2 by rotating the pivots 20 on the bottom of both sides of the water supply frame 3 with the shaft holes 19 on the bottom of both sides of the mounting groove 2, causing the water supply frame 3 to rotate downwards around the pivots 20 to a horizontal position. At this point, since the height of the eyewash nozzles 4 is much lower than the liquid level in the water tank 1, the eyewash liquid, due to its own liquid pressure, flows from the outlet connector 7 along the water pipe 8 into the U-shaped water channel 5, and then is sprayed outwards through the two eyewash nozzles 4 at the end of the U-shaped water channel 5, allowing direct eyewash cleaning of the user's eyes.

[0029] After cleaning, the water supply frame 3 can be rotated upwards to snap into the installation slot 2 again. At this time, the horizontal height of the two eyewash nozzles 4 on the water supply frame 3 is higher than the height of the water tank 1, so that the liquid in the water tank 1 will no longer flow out of the eyewash nozzles 4.

[0030] The entire device only requires the size of water tank 1, allowing it to be moved easily and conveniently when there is a small amount of liquid or no liquid inside. Furthermore, during use, the eye-cleaning effect is achieved entirely by the pressure of the liquid within water tank 1. Therefore, the device does not require an additional water pump or other complex structures, nor does it need electrical connection, making it extremely simple to use.

[0031] In Embodiment 2, as a further preferred embodiment of Embodiment 1, the two side walls of the mounting groove 2 are provided with snap-fit ​​protrusions 17, and the two sides of the outer surface of the water conveyor 3 are provided with snap-fit ​​grooves 18, with the snap-fit ​​protrusions 17 cooperating with the snap-fit ​​grooves 18. Therefore, when the water conveyor 3 is rotated upward so that it fits into the mounting groove 2, it can be snapped into the snap-fit ​​grooves 18 on both sides of the water conveyor 3 by the snap-fit ​​protrusions 17 on the two side walls of the mounting groove 2, thereby achieving the snap-fit ​​fixing effect of the water conveyor 3. When it is necessary to remove the water conveyor 3 from the mounting groove 2, only an outward force needs to be applied to the water conveyor 3.

[0032] In embodiment three, as a further preferred embodiment one, a support protrusion 11 is provided on the lower outer side of the water conveyor frame 3. Therefore, when the water conveyor frame 3 is rotated downwards to a horizontal state, the support protrusion 11 can provide support for the water conveyor frame 3, preventing the water conveyor frame 3 from directly contacting the ground and causing wear problems.

[0033] In Example 4, as a further preferred embodiment of Example 3, a snap-fit ​​groove 9 is provided in the middle of the lower end face of the water conveyor 3. Snap-fit ​​protrusions 10 are provided on both sides of the snap-fit ​​groove 9, and the water pipe 8 is movably snapped into the snap-fit ​​groove 9. By providing the snap-fit ​​groove 9, the water pipe 8 is snapped into the snap-fit ​​groove 9, and the snap-fit ​​protrusions 10 achieve a restraining effect on the water pipe 8, thereby preventing the water pipe 8 from detaching at both ends due to the rotation of the water conveyor 3.

[0034] In Example 5, as a further preferred embodiment of Example 1, pipe clamps 16 are provided at both ends of the water pipe 8. The pipe clamps 16 are used to lock the ends of the water pipe 8 at the points where they connect to the inlet connector 6 and the outlet connector 7, respectively. This effectively ensures the tightness of the connection between the two ends of the water pipe 8 and the inlet connector 6 and the outlet connector 7, thereby further preventing the two ends of the water pipe 8 from detaching from the inlet connector 6 and the outlet connector 7.

[0035] In Example 6, as a further preferred embodiment of Example 1, a handle 13 is provided on the upper surface of the water tank 1. The handle 13 facilitates the carrying and moving of the entire water tank 1.

[0036] In Example 7, as a further preferred embodiment of Example 1, an outer cover 14 is threaded onto the water inlet. A locking ring is provided on the side of the outer cover 14, and a locking lug is provided on the side of the water tank 1, with the locking ring and locking lug corresponding to each other. The water inlet facilitates the replenishment of cleaning fluid in the water tank 1, while the outer cover 14 effectively ensures the cleanliness of the cleaning fluid in the water tank 1. By providing a mutually cooperating locking ring and locking lug, after the cleaning fluid has been added and the outer cover 14 is closed onto the water inlet, the locking ring can be used to connect and lock the locking ring and locking lug, preventing the outer cover 14 from being accidentally opened.

[0037] In Example 8, as a further preferred embodiment of Example 1, a sign 15 is fixedly installed on the outer side of the water conveyor 3. The sign 15 can instruct users on how to use the device.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
