[0002] Rotating eyewash stations are mainly used in hazardous work areas and laboratories, such as pharmaceutical, chemical, petrochemical, and electronic companies. These places often have the risk of chemical splashes or toxic substance leaks. Rotating eyewash stations can quickly minimize the hazards and reduce the harm of toxic substances to workers.

[0003] Existing rotary eyewash stations require water to be added and pressurized to the appropriate pressure before use. The water inlet control valve and dust cover must be opened. The eyewash switch push-plate must be gently pushed clockwise or the pedal pressed. The nozzle is then aimed at the eyes, and the handle is pressed to begin flushing. In practice, workers who encounter emergencies and need to treat their eyes often struggle to locate the water inlet control valve, dust cover, and other equipment, making it difficult to quickly clean their eyes and minimize injury.

[0004] In addition, the rotary adjustable eyewash used in the prior art requires multiple pipe connections through hoses and hard pipes to achieve multi-directional movement, which increases the length of the water outlet pipe, thereby delaying the time for water to flow quickly to the nozzle, increasing the harm of chemicals to workers.

For example, these terms may refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; or internal communication between two components. Those skilled in the art will appreciate the specific meanings of these terms in the present invention based on the specific circumstances.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0026] This embodiment relates to a table-mounted rotating eyewash station. Generally speaking, Figures 1 to 14 As shown, the table-mounted rotary eyewash station includes a fixed part 1 fixed on the workbench, a water inlet pipe 2 connected to the fixed part 1, a rotating component 3 sleeved on the outside of the fixed part 1, a cleaning component 4 connected to the rotating component 3, and a valve core component 5 pivotally connected to the middle of the fixed part 1.

[0027] Among them, the fixed part 1 has an accommodating cavity 101 formed inside to accommodate the valve core assembly 5, the rotating component 3 is connected to the valve core assembly 5, the cleaning component 4 has a flushing channel 401, and a connecting cavity 6 is formed between the valve core assembly 5 and the accommodating cavity 101. The cleaning component 4 has a working state and a reset state. When the cleaning component 4 is driven to rotate from the reset state to the working state, the rotating component 3 and the valve core assembly 5 rotate by a predetermined angle, and the connecting cavity 6 connects the flushing channel 401 with the water inlet pipe 2. When the cleaning component 4 is in the reset state, the connecting cavity 6 rotates and is misaligned with the flushing channel 401, and the water inlet pipe 2 is blocked from the flushing channel 401. The cleaning component 4 also includes a regulating part 15 for adjusting the fluid flow in the flushing channel 401.

[0028] As described above, the table-mounted rotary eyewash of this embodiment is fixed on the laboratory workbench by providing a fixing portion 1, and the rotating component 3 is connected to the cleaning component 4 and the valve core component 5. When the staff needs to flush, the cleaning component 4 is manually driven to rotate, and the cleaning component 4 rotates from the reset state to the working state. At the same time, the valve core component 5 rotates accordingly by a predetermined angle, so that the connecting cavity 6 connects the flushing channel 401 and the water inlet pipe 2. When the cleaning component 4 is in the working state position, the water channel is connected, and flushing is automatically performed. There is no need for multi-step operations as in the prior art, and flushing of the staff can be achieved more quickly.

[0029] Furthermore, when the cleaning assembly 4 is in operation, the water inlet pipe 2 communicates with the flushing channel 401 via the connecting cavity 6, allowing water to quickly reach the nozzle 404, shortening the waterway layout and further reducing flushing preparation time. Furthermore, by providing a regulating portion on the flushing channel to adjust the fluid flow, the flow rate of the flushing water can be adjusted at any time to meet the flushing needs of the staff and avoid wasting water. The present invention has a simple structural arrangement and can effectively and quickly flush the eyes of staff, reducing the risk of harm to staff caused by chemicals and the like.

[0030] Based on the above overall configuration, an exemplary structure of the table-mounted rotating eyewash station of this embodiment is as follows: Figures 1 to 2 As shown, the eyewash station is used to be installed on the laboratory workbench. The water inlet pipe 2 passes through the workbench. There is a water pump and a bucket for water supply at the bottom of the workbench. The bucket is used to set disinfected flushing water. Figure 1 As shown, the outer side of the water inlet pipe 2 is provided with a thread and is located at the back of the workbench. A nut is sleeved on the water inlet pipe 2 to fix the eyewash. A water tank is also provided on the workbench. When the cleaning component 4 is rotated to the working state, the cleaning component 4 is just above the water tank.

[0031] Preferably, the cleaning assembly 4 of this embodiment is mounted on a table and can be opened by rotating it at a 90° angle. When in use, the cleaning assembly 4 is manually driven to the top of the laboratory sink, i.e., in working state. After use, the cleaning assembly 4 is rotated to the side of the laboratory sink to not occupy laboratory space.

[0032] When the cleaning component 4 is in the working state, the nozzle is located in the middle of the water tank. When it is rotated to the reset state, the nozzle is parallel to one side of the water tank. The opening and closing positions of the cleaning component 4 make the nozzle always located in the water tank cavity, preventing water from flowing onto the floor or table of the laboratory, thereby ensuring the sanitary environment of the laboratory.

[0033] As a preferred embodiment, Figures 1 to 4 As shown, the fixed portion 1 includes a valve seat 102, and the rotating assembly 3 includes a sleeve 301 that is sleeved on the outside of the valve seat 102. The cleaning assembly 4 includes a connecting pipe 402 radially connected to the sleeve 301, an elbow 403 vertically connected to the end of the connecting pipe 402, and nozzles 404 provided at both ends of the elbow 403. The flushing channel 401 is formed in the connecting pipe 402 and the elbow 403. The valve seat 102 is provided with a first flow portion 1021, and the sleeve 301 is provided with a second flow portion 3011. The first flow portion 1021 is connected to the connecting chamber 6. When the cleaning assembly 4 is in the working state, the first flow portion 1021 and the second flow portion 3011 are connected.

[0034] like Figures 1 to 4As shown, the valve seat 102 and sleeve 301 of this embodiment both employ a rotary structure, the connecting pipe 402 and elbow 403 utilize circular tubes, and the nozzle 404 structure is identical to that of the prior art and will not be described in detail here. Both the connecting pipe 402 and elbow 403 are made of metal tubes, allowing water to flow directly through the connecting cavity 6 and into the connecting pipe 402 without requiring additional connections, thereby improving water flow efficiency.

[0035] like Figure 3 and Figure 4 As shown, the bent pipe 403 includes a straight section 4031 vertically connected to the connecting pipe 402, and a curved section 4032 connected at both ends of the straight section 4031. The adjusting portion includes an adjusting pin 1501 screwed on the middle part of the straight section 4031, a fourth sealing ring 1502 sleeved on the adjusting pin 1501, and a top screw 1503 for fixing the adjusting pin 1501.

[0036] As Figures 2 to 3 As shown, a connecting block 4033 is provided in the middle of the straight section 4031 and is sleeved on the connecting pipe 402. The adjusting pin 1501 is threadedly connected to the connecting block 4033 and can move along the axial direction of the connecting block 4033. A connecting pipeline is formed on the connecting block 4033 and is connected to the inner hole of the connecting pipe 402 and the straight section 4031 at the same time. The straight section 4031 is divided into two sections and is connected to the two ends of the connecting block 4033. When the axial displacement of the adjusting pin 1501 in the connecting block 4033 is adjusted, the fluid flow rate entering the straight section 4031 from the connecting pipe 402 can be adjusted, thereby facilitating adaptation to flushing requirements.

[0037] In addition, if Figure 5 and Figure 6 As shown, the valve core assembly 5 includes a sleeve 501 screwed onto the fixed portion 1, and an upper rotating core 502, a connecting core 503, and a fixed core 504 clamped onto the sleeve 501, which are sequentially arranged in order from top to bottom. The fixed core 504 is provided with a through hole 5041 that communicates with the connecting pipe 402, and the connecting core 503 is formed with a groove 5031 arranged along its own radial direction. When the cleaning assembly 4 is in the working state, the groove 5031 connects the through hole 5041 and the second circulation portion 3011, and the sleeve 501 is formed with a connecting hole 5011 arranged along its own radial direction, and the connecting hole 5011 is arranged corresponding to the second circulation portion 3011.

[0038] like Figure 5 and Figure 6 As shown, the sleeve 501 is screwed and fixed to the fixing part 1, and the inner hole of the sleeve 501 is used to accommodate the upper rotating core 502, the connecting core 503 and the fixed core 504. The upper rotating core 502 is provided with a shoulder, and the sleeve 501 is provided with an annular groove for accommodating the shoulder, which is used to limit the displacement of the upper rotating core 502 in the height direction. Figure 6As shown, the fixed core 504 is provided with two fan-shaped through holes 5041, and the through holes 5041 and the groove 5031 are both arranged along the axial direction of the sleeve 501. The first flow portion 1021 is formed as a long slot on the valve seat 102, and the second flow portion 3011 is formed as a long slot on the sleeve 301.

[0039] Preferably, still as Figure 5 As shown, a flow cavity 1022 is formed inside the valve seat 102, and the sleeve 501 is arranged in the flow cavity 1022. A flow gap 1023 is provided between the sleeve 501 and the flow cavity 1022. When the cleaning component 4 is in the working state, the first flow portion 1021 is connected to the second flow portion 3011, and the combination Figure 7 and Figure 11 As shown, the through-hole 5041 is connected to the groove 5031 in a corresponding manner. In this case, cleaning water can enter the through-hole 5041 through the water inlet pipe 2, flow into the first circulation portion 1021 and the second circulation portion 3011 through the groove 5031, and finally reach the nozzle 404. When the cleaning assembly 4 rotates to the reset state, the connecting core 503 rotates so that the groove 5031 and the through-hole 5041 do not correspond. The water cannot enter the connecting core 503, thereby blocking the water flow.

[0040] In addition, if Figure 5 and Figure 6 As shown, the sleeve 301 has an inner cavity 3012 formed therein, with the fixing portion 1 disposed below the inner cavity 3012. The sleeve 301 is connected to a support block 7, with the upper rotating core 502 inserted below the support block 7. The support block 7 and the valve core assembly 5 are disposed within the inner cavity 3012. The support block 7 is fixed to the sleeve 301 via bolts, and the upper rotating core 502 is inserted and fixed to the support block 7.

[0041] Furthermore, if Figure 5 As shown, an insert block 8 is provided within the support block 7, with a tooth-shaped hole formed therein. A toothed section is formed on the upper portion of the upper rotating core 502 for meshing with the toothed hole. A connecting bolt 9 is also provided between the support block 7 and the upper rotating core 502. By providing the insert block 8 for connection with the upper rotating core 502, the driving force is increased, the rotation angle of the sleeve 301 and the valve core assembly 5 are ensured to be consistent, and the waterway can be accurately opened and closed, thereby preventing waterway leakage caused by insufficient rotation of the valve core assembly 5.

[0042] In addition, if Figure 6 As shown, the outer wall of the upper rotating core 502 is provided with an inwardly recessed limiting groove 5022, within which a limiting clip 16 is engaged, the lower end of which abuts against the upper surface of the sleeve 501. In this embodiment, the provision of the limiting clip 16 prevents axial downward movement of the valve core assembly 5 during rotation, thereby preventing misalignment between the connecting cavity 6 and the flushing channel 401 and reducing the water flow rate, thereby ensuring the operational effectiveness of the rotary eyewash station.

[0043] like Figure 12 As shown, the sleeve 501 in this embodiment further has two oppositely disposed fan-shaped protrusions 5012 formed inside, as shown in FIG. Figure 13 As shown, a rectangular stopper 5023 is further provided on the upper rotating core 502 above the boss 5021; the stopper 5023 rotates in the space between the two fan-shaped bosses 5012, and the angle is the same as the predetermined angle mentioned above, which can form an angle limit for the rotation of the valve core assembly 5, thereby ensuring the conversion between the reset state and the working state of the cleaning assembly.

[0044] In addition, if Figure 12 As shown, an open groove 5013 is further provided in the sleeve 501 , and two opposite sector blocks 5042 are provided radially on the fixed core 504 . The sector blocks 5042 are inserted into the open groove 5013 to lock the fixed core 504 .

[0045] Preferably, if Figure 5 As shown, a first sealing ring 10 is installed between the upper rotating core 502 and the sleeve 501 for sealing, and a second sealing ring 11 is installed between the sleeve 501 and the valve seat 102 for sealing. A third sealing ring 12 is installed between the valve seat 102 and the sleeve 301 for sealing. These sealing rings prevent water from flowing to the upper portion of the upper valve core 502, causing the toothed portion to rust and causing insertion problems.

[0046] Preferably, still as Figure 5 As shown, a radially arranged support plate 1024 is provided within the circulation cavity 1022, with a circulation hole 1025 defined in the middle of the support plate 1024. A seal 13 is also provided below the stationary core 504, abutting against the support plate 1024. The seal 13 of this embodiment is formed into a bowl-shaped structure with an outwardly extending tapered edge formed at its lower portion. During installation, the extrusion force of the seal 13 is adjusted by adjusting the depth of insertion of the upper rotating core 502 into the insert 8. After installation, the seal 13 abuts between the sleeve 501 and the support plate 1024. When the cleaning assembly 4 is in the reset state, water will not flow through the gap between the sleeve 501 and the support plate 1024 into the aforementioned circulation gap 1023.

[0047] In addition, in order to facilitate the rotation of the connecting core 503, as shown in FIG. Figure 8 and Figure 13 As shown, a slot 5032 is provided on the connecting core 503 , and a downwardly protruding boss 5021 is formed on the upper rotating core 502 . The boss 5021 is inserted into the slot 5032 , and the connecting core 503 rotates with the upper rotating core 502 .

[0048] like Figure 5 As shown, the connecting core 503 of this embodiment includes an upper ferrule 5033 and a lower ferrule 5034. Figures 8 and 9As shown, the slot 5032 is formed on the upper part of the upper insert 5033. The slot 5032 is formed into a cross-shaped structure, which can adapt to the adjustment of the connection direction between the boss on the upper rotating core 502 and the connecting core 503, and is convenient for adapting to the toothed connection between the upper rotating core 502 and the above-mentioned insert block 8.

[0049] like Figure 5 、 Figure 9 、 Figure 10 、 Figure 11 As shown, the upper ferrule 5033 is plugged and fixed to the lower ferrule 5034. A rectangular insert 50331 is provided on the lower back of the upper ferrule 5033, and a rectangular groove 50341 is provided on the lower ferrule 5034 to accommodate the rectangular insert 50331. In addition, the upper ferrule 5033 is also provided with inserting edges 50332 that are inserted into the two sides of the lower ferrule 5034. The two inserting edges 50332 respectively abut the two sides of the lower ferrule 5034, ensuring a secure connection between the upper ferrule 5033 and the lower ferrule 5034 and preventing twisting that would cause an inaccurate rotation angle.

[0050] like Figure 4 and Figure 13 As shown, the bottom of the valve seat 102 further includes a bottom plate 1026 disposed on a workbench, the bottom plate 1026 is provided with a limit pin 14, and the sleeve 301 is formed with an arcuate groove 3013, with part of the limit pin 14 disposed in the arcuate groove 3013. By providing the limit pin 14 and the arcuate groove 3013, the accuracy of the rotation angle of the cleaning assembly 4 can be ensured.

[0051] In addition, if Figure 5 and Figure 6 As shown, a friction ring 17 is also sleeved on the bottom of the valve seat 102, and a ring groove for accommodating the friction ring 17 is provided in the sleeve 301. The friction ring 17 is made of wear-resistant material, and the longitudinal section of the friction ring 17 is L-shaped, which can withstand the axial and radial friction between the sleeve 301 and the valve seat 102, protect the sleeve 301 and the valve seat 102, reduce wear, and increase service life.

[0052] The table-mounted rotary eyewash station of this embodiment can reduce the setting of manual switches through the above-mentioned settings. Workers whose eyes are contaminated only need to manually drive the cleaning component 4 to rotate to achieve the need for flushing with flushing water from the nozzle 404. In order to increase water channel control, an electric control valve can be set at the water pump outlet to control the flow rate and pressure of the water flow.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
