[0029] like Figure 1As shown, the utility model provides a multi-mode eyewash station, including:

[0030] Clean water direct flushing flow path a, clean water immersion flow path b and physiological saline direct flushing flow path c;

[0031] The clean water direct flushing flow path a and the clean water immersion flow path b are both connected to the water pipe 1, and the water pipe 1 is provided with a filter 2, the filter 2 is used to filter the solid particle impurities in the tap water, and then divide it into two paths to transport the filtered clean water to the clean water direct flushing flow path a and the clean water immersion flow path b;

[0032] Two first eyewash nozzles 5 are arranged at the top of the clean water direct flushing flow path a, and an immersion container 7 is arranged at the top of the clean water immersion flow path b; a first pressure valve 4 and a second pressure valve 6 are respectively arranged on the water pipelines of the clean water direct flushing flow path a and the clean water immersion flow path b, and the first pressure valve 4 and the second pressure valve 6 are respectively used to control the water flow of the first eyewash nozzle 5 and the immersion container 7;

[0033] The bottom end of the saline direct flushing flow path c is connected to the saline source 8, and a water pump 9 and a third pressure valve 10 are provided on the water pipeline. Two second eyewash nozzles 11 are provided at the top of the saline direct flushing flow path c. The water pump 9 is used to extract the saline and output it to the second eyewash nozzle 11, and the water outlet flow of the second eyewash nozzle 11 is adjusted by the third pressure valve 10.

[0034] In this embodiment, three flow path modes, namely, a clean water direct flushing path, a clean water immersion flow path and a physiological saline direct flushing path, are provided to meet the cleaning requirements of the laboratory where the eyes are easily stimulated by various chemical substances. In addition, the clean water direct flushing path or the physiological saline direct flushing path can be used for direct flushing first, and then the clean water immersion flow path can be used for immersion, making the eyewash process more professional and convenient.

[0035] In some embodiments, the present invention further comprises: a water tank 3, a drain pipe 12 and a downpipe 13, wherein the bottom end of the water tank 3 is connected to the drain pipe 12, and the drain pipe 12 is connected to the downpipe 13;

[0036] The water outlets of the clean water direct flushing flow path a, the clean water immersion flow path b and the saline direct flushing flow path c are all arranged in the water tank 3. The waste water from the clean water direct flushing flow path a, the clean water immersion flow path b and the saline direct flushing flow path c for cleaning the eyes flows into the water tank 3 and is discharged through the drain pipe 12.

[0037] In this embodiment, the eyewash nozzles and immersion container 7 of the clean water direct flushing flow path a, the clean water immersion flow path b and the normal saline direct flushing flow path c are all arranged in the water tank 3. The waste water from cleaning the eyes through the clean water direct flushing flow path a, the clean water immersion flow path b and the normal saline direct flushing flow path c can directly flow into the water tank 3 and be discharged through the drain pipe 12.

[0038] In some embodiments, the immersion container 7 is also provided with a drain port, and the drain port can be opened to allow the clean water stored in the immersion container 7 to flow into the water tank 3. The drainage method is simple and convenient, and the operation is simple in an emergency, avoiding wasting emergency rescue time.

[0039] In some embodiments, the bottom ends of the four eyewash nozzles of the clean water direct flushing flow path a and the physiological saline direct flushing flow path c are connected to the bendable and shaped metal tube 15 so that the eyewash nozzles can move freely.

[0040] In the present embodiment, the clean water direct flushing flow path a and the physiological saline direct flushing flow path c are both provided with two eyewash nozzles for cleaning two eyeballs at the same time. However, since the eye distance of each experimenter is different, the spacing distance between the two eyewash nozzles needs to be slightly adjusted according to the eye distance of the experimenter, and it is obviously time-consuming to use a fine screw device to adjust the distance in an emergency. Therefore, in the present embodiment, a bendable and shaped metal tube 15 is provided at the bottom of each eyewash nozzle. Then, the experimenter only needs to grasp the bendable and shaped metal tube to adjust the position to move the position of the eyewash nozzle and adjust the spacing. This is not only simple to operate, but also convenient and fast, and is suitable for eye cleaning in emergency situations.

[0041] In some embodiments, a support frame is further included under the bendable shaped metal tube 15, and a bendable shaped metal tube is respectively provided at both ends of the support frame for supporting two eyewash nozzles.

[0042] In this embodiment, the two eyewash nozzles of the clean water direct flushing flow path a or the physiological saline direct flushing flow path c need to be maintained at a horizontal height, and the spacing does not need to be adjusted significantly, only slight adjustments are required. Therefore, a horizontal support frame needs to be set under the bendable and shaped metal tubes of the two eyewash nozzles so that the two eyewash nozzles are located at both ends of the support frame.

[0043] In some embodiments, it also includes: a first telescopic platform 14 and a second telescopic platform 16, which are respectively arranged under the support frames of the clean water direct flushing flow path a and the physiological saline direct flushing flow path c, and are used to adjust the height of the eyewash nozzle.

[0044] In this embodiment, due to the differences in heights of the experimenters, the bendable shaped metal tube is used to adjust the horizontal spacing, and the height adjustment requires the additional provision of a telescopic table.

[0045] In some embodiments, a medicine liquid tank 17 is provided on the water pipeline of the clean water direct flushing flow path a, and a control valve is provided between the medicine liquid tank 17 and the water pipeline for adjusting the flow rate of the medicine liquid. A medicine liquid tank 17 is provided on the water pipeline of the clean water direct flushing flow path a, and a control valve is provided between the medicine liquid tank 17 and the water pipeline for adjusting the flow rate of the medicine liquid.

[0046] In this embodiment, there are clean water cleaning flow paths and physiological saline cleaning flow paths, but the chemical properties in the laboratory are diverse, and some chemical substances require special liquid medicine for cleaning. Therefore, a liquid medicine tank 17 is set on the water pipeline of the clean water direct flushing flow path a, and a control valve is set between the liquid medicine tank 17 and the water pipeline to adjust the flow rate of the liquid medicine. Then, as the clean water flows out, the liquid medicine will be diluted and flow out from the first eyewash nozzle 5 for eye cleaning.

[0047] In some embodiments, reference may be made to Figure 2 A circular arc-shaped insert 18 is arranged on one side of the top of the eyewash nozzle, and the insert 18 has concave and smooth arc-shaped edges from the top to both sides, which are used to open the eyelids.

[0048] In this embodiment, people will close their eyes unconsciously when under the direct flow of water, and the eyes will be more sensitive when chemical substances enter the eyes, and the eyes will be closed reflexively, which will easily affect the cleaning effect. Therefore, a circular arc-shaped insert 18 is provided on one side of the top of each eyewash nozzle, and the top and both sides of the insert 18 are concave and smooth arc-shaped edges, which are used to open the eyelids and help the experimenter clean the eyeballs.

[0049] Next, taking methanol as an example, the steps for using the multi-mode eyewash station are explained.

[0050] Methanol is a very common chemical reagent in laboratories, but methanol vapor can damage human respiratory mucosa and vision. Methanol has an anesthetic effect on the central nervous system and has a special selective effect on the optic nerve and retina, causing lesions and metabolic acidosis. When methanol vapor invades the eyes of the experimenter, the multi-mode eyewash station in this embodiment needs to be used for professional eye cleaning.

[0051] Route a is a clean water direct flushing path, route b is a clean water immersion path, and route c is a physiological saline direct flushing path. When an emergency occurs, choose route a or route c to flush the eyes according to the situation. After flushing for a certain period of time, choose route b for clean water immersion to thoroughly clean the substances that invade the eyes, and all waste water will be drained into the sewer pipe. The lower connection of the eyewash nozzle of route a or route c is a bendable and shaped metal pipe. The spacing between the eyewash nozzles can be adjusted according to the difference in eye distance of each person, and the height of the eyewash nozzle can be adjusted with the first telescopic platform 14 or the second telescopic platform 16. When multiple people need to wash at the same time in an emergency situation, multiple people can operate at the same time.

[0052] The eyewash station of this embodiment is easy to operate and can provide professional eye cleaning for the experimenter in time when an emergency occurs. After a simple cleaning operation, the experimenter can choose to go to the doctor or rest according to the situation.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
