Description

Technical Field

[0001] This utility model relates to the field of water receiving tray technology, and in particular to the Coanda effect water receiving tray. Background Technology

[0002] When collecting the falling medicine, a drip tray is needed to facilitate its subsequent reuse.

[0003] When catching rapidly falling liquid medicine, the initial drop will land on the top of the side wall of the catching tray. At this point, the liquid will collide with the side wall of the catching tray under the influence of gravity and splash. The splashed liquid droplets will drip onto other products during the movement, or alkaline liquids will drip onto acidic liquids, causing contamination and damage to the liquid. To solve the above problems, this application proposes the Coanda effect catching tray. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a Coanda effect water receiving tray. To prevent the medicine from splashing everywhere, a raised water receiving plate is provided on the water receiving tray using the Coanda effect. This plate can collect the fluid and prevent it from being contaminated, thus protecting the medicine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The Coanda effect water receiving tray includes a tray body, a water receiving groove on the top of the tray body, a water receiving plate above the tray body, a protrusion at one end of the water receiving plate, a rotating rod fixedly connected to the water receiving plate on the same axis, the rotating rod being rotatably connected to the tray body, a first gear being fixedly connected to the front end of the rotating rod, the first gear meshing with a second gear, and an adjustment mechanism being provided on the second gear.

[0007] Preferably, the adjusting mechanism includes a rotating rod fixedly connected to the second gear on the same axis. The rear end of the rotating rod is rotatably connected to the outer wall of the disc body. A worm gear is fixedly connected to the outer wall of the rotating rod. The worm gear meshes with a worm. A handle is fixedly connected to the top of the worm. Two limiting blocks are fixedly connected to the outer wall of the disc body. The worm passes through the limiting blocks and is rotatably connected to them.

[0008] Preferably, the height of one end face of the disc is lower than the height of the other three end faces, the water receiving plate is located above the lower end face, and the top of the lower end face of the disc has an inclined surface.

[0009] Preferably, the protrusion is arranged in the form of an arc surface, and the protrusion is located on the side of the water receiving plate away from the inclined surface.

[0010] Preferably, the rear end of the rotating rod is rotatably connected to the inner wall of the disc, the front end of the rotating rod penetrates the disc, and the rotating rod is coaxially arranged with the first gear.

[0011] Preferably, the inner wall of the disc is provided with a protective layer, which is a zinc-plated layer.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By utilizing the raised arc surface structure on the water receiving plate, the Coanda effect is used to change the flow direction of the medicine, so that the vertically falling medicine flows and drips along the bottom of the water receiving plate, instead of directly hitting the straight wall of the water receiving tray and splashing. This avoids splashed medicine dripping into other products or medicines of different properties, prevents medicine contamination and damage, and improves the safety and reliability of the collection process.

[0014] 2. The rotation angle of the water receiving plate can be flexibly adjusted through the worm gear transmission mechanism, changing the position of the protrusion. Adjusting the rotation angle of the water receiving plate can adapt to different drug collection scenarios with different heights, flow rates, or falling angles, ensuring that the drug can always contact the optimal position of the protrusion, optimizing the collection effect, and improving the versatility and flexibility of the device.

[0015] In summary, to prevent the medicine from splashing everywhere, a raised water-receiving plate is installed on the water-receiving tray using the Coanda effect. This plate can collect the fluid and prevent it from being contaminated, thus protecting the medicine. Attached Figure Description

[0020] 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.

[0021] Reference Figures 1-3The Coanda effect water receiving tray includes a tray body 1. A water receiving groove 2 is provided on the top of the tray body 1 to collect the medicine dripping from the water receiving plate 4, thus achieving centralized collection of the medicine. The inner wall of the tray body 1 is provided with a protective layer, which is a galvanized layer. The protective layer plays a protective role in preventing the tray body 1 from being corroded by the medicine and extending the service life of the water receiving tray. The height of one end face of the tray body 1 is lower than the height of the other three end faces. The water receiving plate 4 is located above the lower end face. A slope 3 is provided on the top of the lower end face of the tray body 1. The slope 3 can guide the medicine to flow along the slope 3 towards the lower end of the water receiving tray, which facilitates the collection of the medicine.

[0022] A water receiving plate 4 is provided above the plate 1. A protrusion 5 is provided at one end of the water receiving plate 4. The protrusion 5 is set in an arc shape and is located on the side of the water receiving plate 4 away from the inclined surface 3. The Coanda effect is used to change the flow direction of the medicine, so that the medicine flows along the bottom of the water receiving plate 4 and drips down, preventing the medicine from splashing.

[0023] A rotating rod 6 is fixedly connected to the water receiving plate 4 on the same axis. The rotating rod 6 is rotatably connected to the disc body 1. The rear end of the rotating rod 6 is rotatably connected to the inner wall of the disc body 1. The front end of the rotating rod 6 is set through the disc body 1. The rotating rod 6 provides support and rotation center for the rotation of the water receiving plate 4, so that the water receiving plate 4 can rotate around the rotating rod 6. The rotating rod 6 is coaxially set with the first gear 7. The front end of the rotating rod 6 is fixedly connected to the first gear 7. The first gear 7 meshes with the second gear 8. Through gear meshing transmission, the rotation of the second gear 8 is transmitted to the rotating rod 6 to drive the water receiving plate 4 to rotate.

[0024] The second gear 8 is equipped with an adjustment mechanism, which includes a rotating rod 9 coaxially and fixedly connected to the second gear 8. The rear end of the rotating rod 9 is rotatably connected to the outer wall of the disc body 1. A worm gear 10 is fixedly connected to the outer wall of the rotating rod 9. The worm gear 10 meshes with a worm 11. The rotation adjustment of the second gear 8 is achieved through the worm gear transmission, thereby controlling the rotation angle of the water receiving plate 4. The worm gear has self-locking properties, which can ensure the stability of the water receiving plate 4 after the angle is adjusted. A handle 13 is fixedly connected to the top of the worm 11. Two limit blocks 12 are fixedly connected to the outer wall of the disc body 1. The worm 11 passes through the limit blocks 12 and is rotatably connected to them.

[0025] In this invention, rapidly falling liquid (in the form of a liquid column) first contacts the protrusion 5 on the receiving plate 4. Through the Coanda effect (the phenomenon that when a fluid comes into contact with and flows over a curved surface, the fluid does not flow in a straight line but flows along the shape of the curved surface), the vertically falling liquid accumulates at the bottom of the receiving plate 4 and finally drips down, thus preventing splashing and collecting the rapidly falling liquid. The operator can hold the handle 13 and rotate it to drive the worm gear 11, worm wheel 10, rotating rod 9, second gear 8, first gear 7, rotating rod 6, and protrusion 5 to rotate, causing the receiving plate 4 to rotate around the rotating rod 6 as the center of rotation. This allows the position of the protrusion 5 to be adjusted, so that the rapidly falling liquid contacts different positions on the protrusion 5, resulting in a good collection effect for the rapidly falling liquid.
