Technical Field
[0001] This utility model relates to the field of eyewash stations, and more particularly to an eyewash station that is easy to adjust in angle and has deep self-cleaning capabilities. Background Technology
[0002] In many fields such as chemical engineering, laboratories, and industrial manufacturing, workers are frequently exposed to various hazardous factors such as chemicals and dust, posing a high risk of eye and body contamination or injury. Eyewash stations, as an important safety device, serve to provide timely eye and body rinsing in emergencies, mitigating the severity of injury and buying time for subsequent medical treatment. Flow-through, freeze-proof eyewash stations are specifically designed for low-temperature environments, ensuring that the water system does not freeze and remains operational in cold climates, thus guaranteeing the safety of workers during winter or in cold regions.
[0003] Traditional eyewash stations generally have a simple mechanical structure. Their showering section typically consists of a fixed shower head connected to a water pipe, with the water flow controlled by a manual valve. Water travels directly from the water source to the shower head. The eyewash section is usually a simple shower head connected to a water pipe, also operated manually. The shower head angle is mostly fixed and non-adjustable, failing to meet the personalized needs of different users. Regarding freeze protection, some eyewash stations use electric heating, wrapping heating wire around the pipes to prevent the water from freezing; others wrap the equipment with insulation material to reduce heat loss. However, these methods suffer from high energy consumption and unstable insulation performance.
[0004] However, the nozzle angle of traditional eyewash stations is fixed. Since different users have different heights, body types, and postures when injured, the fixed-angle nozzle cannot be adjusted according to the needs of different users. Therefore, an eyewash station with easy angle adjustment and deep self-cleaning is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an eyewash station that is easy to adjust in angle and has deep self-cleaning capabilities, aiming to improve the problem that the nozzle angle of traditional eyewash stations in the prior art is fixed and cannot be adjusted according to the needs of different users.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An eyewash station with adjustable angle and self-cleaning depth includes a fixed tube, a connecting tube fixedly connected to the side wall of the fixed tube, a shower head fixedly connected to the side wall of the connecting tube, a pull ring provided on the side wall of the connecting tube, a drain pipe fixedly connected to the side wall of the fixed tube, an adjustment component provided on the side wall of the drain pipe, a fixing component provided on the side wall of the drain pipe, and a push plate provided on the side wall of the drain pipe.
[0008] The adjustment assembly includes an eyewash basin, the bottom of which is fixedly connected to the side wall of the drain pipe. A fixed plate is fixedly connected inside the eyewash basin. A connecting rod is rotatably connected between the fixed plates. A connecting frame is fixedly connected between the connecting rods. A telescopic tube is fixedly connected to the side wall of the connecting frame. The side wall of the telescopic tube is fixedly connected to the inside of the eyewash basin. A worm gear is fixedly connected to the side wall of one connecting rod. A worm is rotatably connected inside the fixed plate on one side. The worm gear meshes with the worm. A handle is rotatably connected to the side wall of one fixed plate. The side wall of the handle is fixedly connected to the side wall of the worm. A connecting block is fixedly connected to the side wall of the connecting rod. A water supply pipe is fixedly connected inside the connecting block.
[0009] As a further description of the above technical solution:
[0010] The fixing component includes a nozzle housing, the bottom of which is fixedly connected to the side wall of the water supply pipe;
[0011] As a further description of the above technical solution:
[0012] The nozzle housing is slidably connected to a spray head, and a protective cover is rotatably connected to the side wall of the spray head;
[0013] As a further description of the above technical solution:
[0014] A rubber ring is fixedly connected to the side wall of the nozzle, and a filter element is slidably connected inside the nozzle housing;
[0015] As a further description of the above technical solution:
[0016] The filter element has recessed holes inside, and the nozzle housing has square grooves inside;
[0017] As a further description of the above technical solution:
[0018] The nozzle housing has a locking block inside, and the side wall of the locking block is slidably connected to the inside of the square groove.
[0019] As a further description of the above technical solution:
[0020] The sidewall of the card block is slidably connected to the inside of the recess, and a spring is provided inside the nozzle housing;
[0021] As a further description of the above technical solution:
[0022] One end of the spring is fixedly connected inside the square groove, and the other end of the spring is fixedly connected to the side wall of the card block.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, rotating the handle causes the worm gear to rotate, which in turn causes the connecting rod to rotate, which in turn causes the connecting block fixed on the side wall to rotate the water pipe, thereby adjusting the nozzle angle. This solves the problem that the nozzle angle of traditional eyewash stations is fixed and cannot be adjusted according to the needs of different users. The above technical solution improves the accuracy of rinsing and helps to remove contaminants more thoroughly.
[0025] 2. In this utility model, the spray head is twisted to remove the filter element, and then the filter element is removed. During the movement, the locking block is squeezed into the square groove and squeezes the spring. The locking block is released from the concave hole and the filter element is removed and cleaned. This solves the problem that the internal structure of traditional eyewash nozzles is relatively closed and it is not easy to perform deep cleaning. The above technical solution improves the cleanliness of the nozzle's interior. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 1 and Figure 2 This utility model provides an embodiment of an eyewash station with adjustable angle and self-cleaning depth, comprising a fixed tube 1, a connecting tube 2 fixedly connected to the side wall of the fixed tube 1, a shower head 3 fixedly connected to the side wall of the connecting tube 2, a pull ring 4 provided on the side wall of the connecting tube 2, a drain pipe 5 fixedly connected to the side wall of the fixed tube 1, an adjusting component provided on the side wall of the drain pipe 5, a fixing component provided on the side wall of the drain pipe 5, and a push plate 7 provided on the side wall of the drain pipe 5; the adjusting component includes an eyewash basin 6, the bottom of the eyewash basin 6 fixedly connected to the side wall of the drain pipe 5, a fixed plate 8 fixedly connected inside the eyewash basin 6, a connecting rod 9 rotatably connected between the fixed plates 8, and a connecting rod 9 fixedly connected between the connecting rods 9. A telescopic tube 11 is fixedly connected to the side wall of frame 10. The telescopic tube 11 can bend according to the rotation angle of the nozzle. The side wall of the telescopic tube 11 is fixedly connected to the inside of the eye basin 6. A worm gear 12 is fixedly connected to the side wall of one side connecting rod 9. The worm gear 12 is used to drive the connecting rod 9 to rotate. A worm 13 is rotatably connected inside one side fixing plate 8. The worm gear 12 and the worm 13 mesh. A handle 14 is rotatably connected to the side wall of one side fixing plate 8. The handle 14 is a convenient operating component for manually adjusting the angle. The side wall of the handle 14 is fixedly connected to the side wall of the worm 13. A connecting block 16 is fixedly connected to the side wall of the connecting rod 9. A water supply pipe 15 is fixedly connected inside the connecting block 16.
[0034] When staff need to rinse both their eyes and body simultaneously, they pull the hand ring 4. The hand ring 4 is a key operating component for activating the shower function. It forms a linkage mechanism with the corresponding valve through a mechanical linkage. When the staff pulls it, it triggers the valve connected to it to open. The water flows from the connecting pipe 2 to the shower head 3. The shape of the shower head 3 and the distribution of the water outlet holes are carefully designed to evenly disperse the water flow into a large coverage area, thoroughly rinsing the staff's body. Then, the push plate 7 is pushed. The push plate 7 is reliably connected to another valve through a rigid linkage or hydraulic transmission. The position and stroke design of the push plate 7 can precisely control the opening degree of the valve. When the push plate 7 is pushed, the resulting force is stably transmitted to the valve, allowing it to open smoothly. At this time, water flows out from the spray head 17 for eyewash. The eyewash station can be adjusted in angle according to individual needs by turning the handle 14. The handle 14 serves as a convenient manual angle adjustment component. When the handle 14 is turned, it can drive the worm gear 13 to rotate with a small torque. The worm gear 13 has a specific helical tooth profile and lead. During rotation, it can efficiently convert the circular motion transmitted from the handle 14 into linear motion and transmit the force to the meshing worm wheel 12. The rotation of the worm wheel 12 drives the connecting rod 9 to rotate. The connecting rod 9 serves as an intermediate transmission connector, which in turn causes the connecting block 16 fixed to the side wall to drive the water pipe 15 to rotate, adjusting the spray head angle to adapt to different needs. To ensure that the water flow accurately reaches the areas requiring rinsing, the connecting frame 10 is connected to a telescopic tube 11. The telescopic tube 11 is made of rubber or plastic with good flexibility and elasticity. Its internal structure design makes it telescopic and bendable. During the adjustment of the nozzle angle, the telescopic tube 11 can bend accordingly according to the rotation angle of the nozzle. At the same time, its telescopic function can compensate for the length change required due to the angle adjustment to a certain extent, ensuring that the water flow can be stably and smoothly transmitted from the water source to the nozzle throughout the entire angle adjustment process. The water flow will not be obstructed due to the change of the nozzle angle, thus ensuring the reliability and stability of the eyewash station under different usage conditions.
[0035] The eyewash station's water supply valve is a three-way valve. The three ports of the three-way valve are connected to the water source, the shower head pipe, and the eyewash head pipe, respectively. Under normal conditions, after the water source flows into the valve, part of the water flow can enter the shower head pipe through one of the channels to maintain the water flow in the pipe and prevent stagnant water from causing bacterial growth or freezing in winter. The other part of the water flow can enter the eyewash head pipe through the other channel, serving a similar purpose. When showering or eyewashing is required, the valve channel is switched by the corresponding control mechanism (such as the aforementioned linkage device between the pull ring or push plate and the valve), so that more water can flow quickly and accurately to the corresponding nozzle to meet emergency rinsing needs.
[0036] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The fixing assembly includes a nozzle housing 22, the bottom of which is fixedly connected to the side wall of the water supply pipe 15. A spray head 17 is slidably connected inside the nozzle housing 22. A rubber ring 19 has good sealing performance to prevent water from leaking from the nozzle connection during spraying. A protective cover 18 is rotatably connected to the side wall of the spray head 17 to prevent dust from falling onto the spray head 17. A rubber ring 19 is fixedly connected to the side wall of the spray head 17. A filter element 20 is slidably connected inside the nozzle housing 22. A recessed hole 21 is opened inside the filter element 20. A square groove 23 is opened inside the nozzle housing 22. A locking block 24 is provided inside the nozzle housing 22. The side wall of the locking block 24 is slidably connected to the inside of the square groove 23 and the recessed hole 21. A spring 25 is provided inside the nozzle housing 22 for rebound and reset. One end of the spring 25 is fixedly connected to the inside of the square groove 23, and the other end of the spring 25 is fixedly connected to the side wall of the locking block 24.
[0037] When cleaning the inside of the eyewash nozzle, first twist the nozzle 17. The nozzle 17, as a key component of the eyewash station that directly contacts the eyes and sprays water, is fixed to the nozzle housing 22 via a threaded connection. Twisting it allows it to be easily separated from the nozzle housing 22 for deep cleaning of the inside. Then remove the filter element 20. The filter element 20 primarily performs the important task of filtering impurities from the water. It effectively blocks any small particles and suspended solids that may be present in the water, preventing these impurities from entering the user's eyes with the water flow. To avoid causing additional damage to the eyes, when the filter element 20 moves, its outer locking block 24 is squeezed into the square groove 23. During this process, the locking block 24 exerts a squeezing effect on the spring 25. The cooperation design between the locking block 24 and the recess 21 achieves the function of fixing the filter element 20. When the locking block 24 is squeezed into the square groove 23, it will disengage from the recess 21, thereby releasing the fixing of the filter element 20. In this way, the filter element 20 can be easily removed for cleaning. After cleaning, the filter element 20 is placed into the nozzle housing 22. At this time, the locking block 24 is squeezed again. Once inside the square groove 23, when the recess 21 aligns with the locking block 24, the spring 25, previously compressed, will spring back upon release of pressure. The spring 25 will then lock the locking block 24 into the recess 21, thus securing the filter element 20 again and ensuring its stable position within the nozzle housing 22, guaranteeing its proper filtration function. Then, the spray head 17 is screwed into the nozzle housing 22. A rubber ring 19 is fixed to the side wall of the spray head 17, providing excellent sealing performance and ensuring a tight fit against the nozzle housing 22. The inner wall effectively fills the tiny gaps between the two, thus preventing water from leaking from the nozzle connection during spraying. Finally, the protective cover 18 is put on. The main function of the protective cover 18 is to prevent dust from falling onto the nozzle 17. If dust enters the nozzle 17, it may clog the nozzle's water outlet, affecting the normal water output function of the nozzle 17. It may also mix into the rinsing water, posing a potential threat to the user's eye health. The protective cover 18 can provide a relatively clean protective space for the nozzle 17, ensuring that the nozzle 17 maintains good performance when not in use.
[0038] Working principle: When the staff needs to rinse their eyes and body at the same time, they pull the handle ring 4 and the valve connected to it to open the water flow from the connecting pipe 2 to the shower head 3 and spray it down. Then, they push the push plate 7 to open the connected valve, and the water flow from the spray head 17 sprays out to rinse the eyes. The eyewash station can be adjusted according to the staff's needs. Turning the handle 14 causes the worm gear 13 to rotate, which drives the worm wheel 12 to rotate. The rotation of the worm wheel 12 drives the connecting rod 9 to rotate, which in turn causes the connecting block 16 fixed to the side wall to drive the water supply pipe 15 to rotate, thereby adjusting the angle of the spray head. The telescopic pipe 11 is connected below the connecting frame 10, and its characteristic is that it can bend and adjust the angle with the spray head.
[0039] When it is necessary to clean the inside of the eyewash nozzle, twist the nozzle 17 to remove it, and then remove the filter element 20. When the filter element 20 moves, the locking block 24 is squeezed into the square groove 23 and squeezes the spring 25. As the locking block 24 disengages from the recess 21, it releases the fixation of the filter element 20, allowing it to be removed for cleaning. After cleaning, put the filter element 20 back into the nozzle housing 22. The locking block 24 is squeezed into the square groove 23 again. When the recess 21 is aligned with the locking block 24, the spring 25 loses its compression and rebounds, locking the locking block 24 into the recess 21 to fix the filter element 20. Then twist the nozzle 17 back into the nozzle housing 22. A rubber ring 19 is fixed to the side wall of the nozzle 17 to prevent water leakage. Finally, put on the protective cover 18 to prevent dust from falling onto the nozzle 17.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
