Description

Technical Field

[0001] This utility model belongs to the technical field of laboratory eyewash stations, specifically relating to a flip-type eyewash station. Background Technology

[0002] Laboratory eyewash stations are safety and rescue equipment used in laboratories. When laboratory staff are accidentally injured by acidic, alkaline, or other harmful substances, they can use laboratory eyewash stations to perform emergency rinsing of the eyes, face, or whole body to reduce the concentration of harmful substances, minimize their damage to the eyes and skin, and buy valuable time for subsequent medical treatment.

[0003] Chinese patent CN219062532U discloses a flip-type double-outlet faucet. Its structure includes a base, an inlet pipe fixedly connected to the base, and outlet pipes respectively located at both ends of the base. The outlet pipes are equipped with switches. A connecting pipe connects the base and the outlet pipes. The inlet pipe, base, connecting pipe, and outlet pipes are sequentially connected. One end of the connecting pipe is fixedly connected to the inlet end of the outlet pipe, and the other end is rotatably connected to the base. A sealing element is provided between the connecting pipe and the base. A limiting spring is fitted onto the connecting pipe. A fixing nut is threaded onto the end of the base connected to the connecting pipe. The limiting spring is pressed between the end face of the base and the fixing nut. The flip-type faucet allows for the flipping of a single outlet pipe through the rotatable cooperation of the connecting pipe and the base. The structure is simple and the flipping is reliable. The fixing nut ensures the stability of the flipped outlet pipe, preventing displacement. Multiple sealing rings on the connecting pipe provide a good sealing effect, reducing leakage during the flipping process.

[0004] Specifically, since eyewash stations are devices specifically designed for cleaning the eyes of laboratory personnel, their water quality requirements are extremely stringent. However, the existing dual-outlet faucets disclosed in the aforementioned technology employ a single filter structure. This structure has significant limitations in filtration effectiveness, resulting in filtered water that falls far short of the safety standards for direct use in rinsing the eyes of laboratory personnel. Therefore, this deficiency directly affects the effectiveness and safety of the eyewash station, potentially posing risks to the eye health of laboratory personnel, thereby impacting the smooth progress of experimental procedures and the overall safety and health of the personnel. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention involves installing a support filter frame inside a treatment box. During the process, an activated carbon plate and a filter screen are installed sequentially from bottom to top inside the support filter frame. The treatment box is then installed between the water outlet pipe and the universal hose via a flange. After controlling the switch, the water flows through the treatment box and undergoes multi-layer filtration, ensuring that clean water flows out of the outlet. This facilitates eye washing for laboratory personnel and avoids discomfort caused by impurities in the experimental water, thus improving the practicality of the eyewash station.

For reference, a flip-type double-outlet faucet disclosed in Chinese Patent (Announcement No. CN219062532U) is provided, so it will not be described in detail here.

[0027] A treatment box 10 is installed between the water outlet pipe 4 and the universal hose 6. A support filter frame 12 is installed on the inner wall of the treatment box 10. An activated carbon plate 13 is installed at the bottom of the inner part of the support filter frame 12. A filter screen 14 is connected to the surface of the activated carbon plate 13.

The surface dimensions of the activated carbon plate 13 and the filter screen 14 match the opening dimensions of the inner wall of the support filter frame 12, and flanges 11 are connected to both ends of the opening of the treatment box 10.

[0029] In practical use, by assembling the activated carbon plate 13 and the filter screen 14, and combining them with the use of the supporting filter frame 12, the effect of multi-layer filtration of experimental water quality is improved, ensuring that experimental personnel can directly rinse their eyes.

[0030] Preferably, the water outlet pipe 4 is connected to the top of the treatment box 10 via a water outlet pipe connection valve 8, and the water outlet pipe 4 is connected to the flange 11 at the bottom of the treatment box 10 via the water outlet pipe connection valve 8. The bottom of the universal hose 6 is connected to a hose connection valve 9, and the universal hose 6 is connected to the flange 11 on the surface of the treatment box 10 via the hose connection valve 9.

[0031] In practical use, the flange 11 is threaded to the outlet pipe connection valve 8 and the hose connection valve 9 respectively, which facilitates the quick and stable assembly of the treatment box 10.

[0032] Preferably, a sealing ring 15 is connected to the flange 11 mating opening, and an installation strip 16 is connected to the side of the sealing ring 15. Both the installation strip 16 and the sealing ring 15 are made of silicone.
