Description

Technical Field

[0001] This utility model relates to the field of rinsing devices, and more specifically, to a rotating nozzle for an eyewash station. Background Technology

[0002] In the daily production and experimental processes of many industries such as chemical engineering and scientific research, eye safety faces numerous potential threats. Splashes of chemical reagents and accidental intrusion of tiny particles occur frequently. If these harmful substances come into contact with the eyes and are not rinsed in a timely and effective manner, they are highly likely to cause serious and irreversible damage to the eye tissues.

[0003] Eyewash nozzles are exposed to the working environment for a long time and are easily contaminated with dust and impurities. Traditional eyewash stations lack an effective automatic reset and protection mechanism after rinsing. The nozzle opening remains open, and if the user forgets to manually reset it, it increases the risk of foreign objects falling in, reducing the reliability and safety of the equipment. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a rotating nozzle for an eyewash station. After rinsing, releasing the extended foot pedal causes the water outlet pressure switch plate to rise under the action of the internal reset structure. Through the cooperation of the spherical movable ball and the circular slot, a series of components rise synchronously. The elastic reset auxiliary ball at the upper end of the follow column pushes the nozzle cover to rotate in the opposite direction around the hinge, re-locking it onto the surface of the rotatable water outlet nozzle, preventing foreign objects from falling in and ensuring the cleanliness and normal performance of the nozzle for the next use.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A rotating nozzle for an eyewash station includes an eyewash station column. A retaining basin is fixedly connected to the upper end of the eyewash station column. A pair of water outlet pipes are fixedly connected to the lower inner wall of the retaining basin. A rotatable water outlet nozzle is fixedly connected to the upper end of the water outlet pipes. A hinge is installed on the outer side of the upper end of the rotatable water outlet nozzle. A nozzle cover is hinged to the outer end of the hinge. A water outlet pressure switch plate is movably connected to the lower right side of the eyewash station column. A linkage vertical rod is provided at the upper end of the water outlet pressure switch plate. An extension side plate is fixedly connected to the upper end of the linkage vertical rod. A connecting horizontal plate is fixedly connected to the end of the extension side plate near the retaining basin. A pair of follower columns are fixedly connected to the end of the connecting horizontal plate near the rotatable water outlet nozzle. An elastic reset auxiliary ball is fixedly connected to the upper end of the follower columns.

[0009] Preferably, a pair of water outlet pipes are connected to valves, and the valves and the water outlet pressure switch plate are interconnected.

[0010] Preferably, the two follow-up columns are located directly below the corresponding nozzle cover, and the elastic reset auxiliary ball and the nozzle cover are in contact with each other.

[0011] Preferably, a wastewater drain outlet is fixedly connected to the lower inner wall of the enclosure basin, and the wastewater drain outlet is located between two water outlet pipes.

[0012] Preferably, an extension pedal is fixedly connected to the front end of the water outlet pressure switch plate, and an anti-slip top plate is fixedly connected to the surface of the extension pedal.

[0014] Preferably, the upper end of the spherical movable ball and the lower end of the linkage vertical rod are connected to each other, and the two nozzle covers and the corresponding hinge openings are engaged with each other.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) After the eyewash station is started, the unique design of the nozzle cover ensures that the rinsing process is efficient. When the rotatable water nozzle sprays water, the water pressure acts directly on the nozzle cover connected by the hinge, causing it to rotate around the hinge axis and open, allowing the water to spray out smoothly. After rinsing, the extended foot pedal is released, and the water outlet pressure switch plate rises under the action of the internal reset structure. Through the cooperation of the spherical movable ball and the circular slot, a series of components rise synchronously. The elastic reset auxiliary ball at the upper end of the follow column pushes the nozzle cover to rotate in the opposite direction around the hinge, re-locking onto the surface of the rotatable water nozzle, preventing foreign objects from falling in, and ensuring the cleanliness and normal performance of the nozzle for the next use.

[0018] (2) A spherical movable ball is set in the circular slot at the top of the water outlet pressure switch plate and connected to the lower end of the linkage rod. By utilizing its rolling characteristics, it ensures that the linkage rod can move down stably and smoothly with the water outlet pressure switch plate, avoiding relative motion jamming, ensuring smooth operation, and enabling users to turn on the eyewash station in the shortest time and seize the golden time for eye rinsing.

[0019] (3) In addition, extending the anti-slip top plate on the pedal surface can increase friction and prevent the user's foot from slipping when stepping, ensuring safety and stability in all aspects of the operation process. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 2-4 A rotating nozzle for an eyewash station includes an eyewash station column 1. A retaining basin 16 is fixedly connected to the upper end of the eyewash station column 1. A pair of water outlet pipes 2 are fixedly connected to the lower inner wall of the retaining basin 16. A rotatable water outlet nozzle 3 is fixedly connected to the upper end of the water outlet pipes 2. A hinge 4 is installed on the outer side of the upper end of the rotatable water outlet nozzle 3. A nozzle cover 5 is hinged to the outer end of the hinge 4. A water outlet pressure switch plate 11 is movably connected to the lower right side of the eyewash station column 1. A linkage vertical rod 10 is provided at the upper end of the water outlet pressure switch plate 11. An extension side plate 9 is fixedly connected to the upper end of the linkage vertical rod 10. A connecting horizontal plate 8 is fixedly connected to the end of the extension side plate 9 near the retaining basin 16. A pair of follower columns 6 are fixedly connected to the end of the connecting horizontal plate 8 near the rotatable water outlet nozzle 3. An elastic reset auxiliary ball 7 is fixedly connected to the upper end of the follower columns 6.

[0027] Please see Figure 2-4A pair of water outlet pipes 2 are connected to valves, and the valves and the water outlet pressure switch plate 11 are connected to each other. Two follow-up columns 6 are located directly below the corresponding nozzle cover 5. The elastic reset auxiliary ball 7 and the nozzle cover 5 are in contact with each other. The lower inner wall of the enclosure basin 16 is fixedly connected to a wastewater drain outlet 15, which is located between the two water outlet pipes 2. The front end of the water outlet pressure switch plate 11 is fixedly connected to an extension foot pedal 12, and the surface of the extension foot pedal 12 is fixedly connected to an anti-slip top plate 17. The upper end of the water outlet pressure switch plate 11 has a circular slot 13, and the inner end of the circular slot 13 is movably connected to a spherical movable ball 14. The upper end of the spherical movable ball 14 is connected to the lower end of the linkage vertical rod 10. The two nozzle covers 5 and the corresponding hinge 4 openings are engaged with each other.

[0028] Please see Figure 1-4 When a user needs to rinse their eyes urgently, they can apply external force by stepping on the extended foot pedal 12. Since the extended foot pedal 12 is fixedly connected to the front end of the water outlet pressure switch plate 11, this force will be transmitted to the water outlet pressure switch plate 11, causing it to move downward. During the downward movement of the water outlet pressure switch plate 11, the spherical movable ball 14 set in the circular slot 13 at its upper end plays a key role. The spherical movable ball 14 is connected to the lower end of the linkage vertical rod 10. With its rolling characteristics in the circular slot 13, it ensures that the linkage vertical rod 10 can move downward stably and smoothly in sync with the downward movement of the water outlet pressure switch plate 11, effectively avoiding the possible jamming phenomenon during the relative movement of the two and ensuring the smoothness of operation.

[0029] As the linkage vertical rod 10 moves downward, the extended side plate 9, which is fixedly connected to it, also descends, thereby driving the connected horizontal plate 8 to move synchronously. The pair of follower columns 6, which are fixedly connected to both ends of the connected horizontal plate 8, also move downward. At the same time, due to the downward action of the water outlet pressure switch plate 11, the water supply mechanism inside the eyewash station is triggered. The water is transported upward through the water outlet pipe 2, and the rotatable water outlet nozzle 3 connected to the upper end of the water outlet pipe 2 starts to work. High-pressure water is sprayed out at high speed from the rotatable water outlet nozzle 3, forming a water flow with a certain impact force to meet the need for rinsing the user's eyes. When the rotatable water outlet nozzle 3 starts to spray water, the pressure generated by the high-speed water flow directly acts on the nozzle cover 5. The nozzle cover 5 is hinged to the upper outer side of the rotatable water outlet nozzle 3 through the hinge 4. Under the action of the water flow pressure, the nozzle cover 5 rotates around the rotation axis of the hinge 4, thereby disengaging from the opening of the rotatable water outlet nozzle 3, so that the water flow can be smoothly sprayed out to rinse the user's eyes.

[0030] After the user finishes rinsing their eyes and releases the force applied to the extended foot pedal 12, the water outlet pressure switch 11 begins to rise under the action of the spring return structure inside the eyewash station. This spring return structure is a known technology and is not shown in detail in the diagram. As the water outlet pressure switch 11 rises, the spherical movable ball 14, in conjunction with the circular slot 13, drives the linkage vertical rod 10, the extended side plate 9, and the connected horizontal plate 8 to rise synchronously. At this time, a pair of follower columns 6 also move upwards. The elastic recoil mechanism located at the upper end of the follower columns 6... As the auxiliary ball 7 gradually approaches the nozzle cover 5, the force of the follower column 6 continuing to rise is transmitted to the nozzle cover 5 through the elastic reset auxiliary ball 7. This pushes the nozzle cover 5 to rotate in the opposite direction around the hinge 4 until the nozzle cover 5 re-engages with the surface of the rotatable water outlet nozzle 3 corresponding to the opening of the hinge 4, thus completing the reset action. This reset mechanism can effectively prevent foreign objects from falling into the interior of the rotatable water outlet nozzle 3 when it is not in use, ensuring the cleanliness and normal working performance of the rotatable water outlet nozzle 3 when it is used again.

[0031] Meanwhile, the anti-slip top plate 17, which is fixedly connected to the surface of the extended pedal 12, effectively prevents the user's foot from slipping by increasing friction during the user's pedaling process, thus ensuring the safety and stability of the operation.

[0032] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
