Description

Technical Field

[0001] This utility model relates to the field of veterinary drug feeding technology, and in particular to a drug feeder. Background Technology

[0002] Veterinary sustained-release emulsions are drug formulations specifically designed for animals. They can provide an effective drug concentration over a longer period of time by slowly releasing the drug, thereby improving the therapeutic effect.

[0003] Sustained-release emulsions release the drug gradually, ensuring a consistent and effective drug concentration in the body. If administration is irregular or inconsistent, the drug concentration may be excessively high for short periods or insufficient for extended periods, leading to unstable efficacy or reduced therapeutic effect. Furthermore, the timed and quantitative administration of sustained-release emulsions helps ensure uniform drug release within the animal's body, allowing for optimal absorption and utilization in the digestive system and various tissues.

[0004] Existing technologies rely on manual, timed, and quantitative drug administration, which results in high labor costs. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a medicine feeder, which aims to solve the problem of high labor costs caused by the manual administration of medicines at regular intervals and in fixed quantities in the prior art.

[0006] This utility model provides a medicine feeder, including a tank, a liquid guide tube, a valve stem, and a drive structure. The liquid guide tube is connected to the tank and located below the tank. An isolation plate is provided inside the liquid guide tube, which divides the liquid guide tube into a first chamber and a second chamber. A through hole is provided on the isolation plate for connecting the first chamber and the second chamber. One end of the valve stem is connected to the power output end of the drive structure, and the other end extends into the tank. A first plug and a second plug are provided on the valve stem. The first plug is located above the isolation plate, and the second plug is located below the isolation plate. The drive structure is used to drive the valve stem to cause the first plug to seal and open the upper end of the liquid guide tube, and to cause the second plug to seal and open the through hole.

[0007] Furthermore, the end of the first plug near the isolation plate is tapered, and the end face of the isolation plate away from the first plug is provided with a conduit, the volume of the tapered body being the same as the volume of the conduit.

[0008] Furthermore, the drive structure includes a drive motor, a rotating shaft, a spring, and a cam. The drive motor is mounted on the tank body, and the power output end of the drive motor is connected to the rotating shaft. The cam is connected to the rotating shaft. A stop ring is provided on the valve stem. One end of the spring abuts against the stop ring, and the other end abuts against the tank body. The spring is used to drive the valve stem to abut against the cam, and the drive motor is used to drive the cam to rotate so as to drive the valve stem to move up and down.

[0009] Furthermore, the valve stem is provided with a roller, which abuts against the cam.

[0010] Furthermore, the tank body is provided with a protective cover, which is used to cover the drive structure.

[0011] Furthermore, the end face of the tank is provided with a liquid inlet, which allows liquid to be added into the tank.

[0012] Furthermore, the lower end face of the tank is a conical surface.

[0013] Furthermore, the lower end of the liquid guide tube is connected to a connecting pipe, and a valve assembly is provided on the connecting pipe, which is used to close and open the connecting pipe.

[0014] Furthermore, the valve assembly includes a valve plug with a flow guide hole, and the valve plug is rotatably connected to the connecting pipe so that the flow guide hole can open or close the connecting pipe.

[0015] Furthermore, the lower end face of the liquid guiding tube is a conical surface.

[0016] Beneficial Effects: This utility model provides a medicine feeder, including a tank, a liquid guide tube, a valve stem, and a drive structure. Since the partition plate divides the liquid guide tube into a first chamber and a second chamber, when slow-release emulsion needs to be fed, the drive structure drives the valve stem to move the first plug and the second valve body upwards simultaneously. The first plug opens the upper end of the liquid guide tube, while the second plug seals the through hole, allowing the slow-release emulsion in the tank to flow into the first chamber and fill it. Subsequently, the drive structure drives the valve stem to move the first plug and the second valve body downwards simultaneously. The first plug seals the upper end of the liquid guide tube, while the second plug opens the through hole, allowing the slow-release emulsion in the tank to flow into and out of the second chamber, completing the dispensing of the slow-release emulsion.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the 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 scope of protection of the present utility model.

[0025] Please see Figures 1 to 6 This utility model provides a medicine feeder, including a tank 1, a liquid guide cylinder 2, a valve stem 3, and a drive structure 4. The liquid guide cylinder 2 is connected to the tank 1 and located below the tank 1. The liquid guide cylinder 2 is provided with a partition plate 21, which divides the liquid guide cylinder 2 into a first chamber 22 and a second chamber 23. The partition plate 21 has a through hole 24 for connecting the first chamber 22 and the second chamber 23. One end of the valve stem 3 is connected to the power output end of the drive structure 4, and the other end extends into the tank 1. The valve stem 3 is provided with a first plug 31 and a second plug 32. The first plug 31 is located above the partition plate 21, and the second plug 32 is located below the partition plate 21. The drive structure 4 is used to drive the valve stem 3 to block and open the upper end of the liquid guide cylinder 2 with the first plug 31 and to block and open the through hole 24 with the second plug 32.

[0026] Specifically, when it is necessary to feed the slow-release emulsion, the drive structure 4 drives the valve stem 3 to move the first plug 31 and the second valve body upwards simultaneously. The first plug opens the upper end of the liquid guide tube 2, and at the same time, the second plug 32 seals the through hole 24. The slow-release emulsion in the tank 1 flows into the first chamber 22 and fills the first chamber 22. Subsequently, the drive structure 4 drives the valve stem 3 to move the first plug 31 and the second valve body downwards simultaneously. The first plug 31 seals the upper end of the liquid guide tube 2, and at the same time, the second plug 32 opens the through hole 24. The slow-release emulsion in the tank 1 flows into the second chamber 23 and flows out from the second chamber 23, completing the feeding of the slow-release emulsion.

[0027] To achieve timed and quantitative control, the drive mechanism can be set to drive the valve stem 3 to move within a certain interval.

[0028] In one feasible implementation, the end of the first plug 31 near the isolation plate 21 is conical, and the end face of the isolation plate 21 away from the first plug 31 is provided with a conduit 25. The volume of the conical body is the same as the volume of the conduit 25. Specifically, when the valve stem 3 moves downward, the conical body first comes into contact with the liquid in the first chamber 22. At the same time, the second plug 32 moves downward, and the liquid in the first chamber 22 flows into the conduit 25. Therefore, during the downward movement of the valve stem 3, the total amount of liquid in the first chamber 22 and the conduit 25 remains unchanged, thus achieving the purpose of metering. When the first plug 31 completely closes the upper end of the liquid guide tube 2, the second plug 32 opens the through hole 24, allowing the liquid in the conduit 25 to enter the second chamber 23.

[0029] In one feasible embodiment, the drive structure 4 includes a drive motor 41, a rotating shaft 42, a spring 43, and a cam 44. The drive motor 41 is mounted on the tank body 1, and its power output end is connected to the rotating shaft 42. The cam 44 is connected to the rotating shaft 42. A stop ring 33 is provided on the valve stem 3. One end of the spring 43 abuts against the stop ring 33, and the other end abuts against the tank body 1. The spring 43 drives the valve stem 3 to abut against the cam 44. The drive motor 41 drives the cam 44 to rotate, thereby driving the valve stem 3 to move up and down. In this embodiment, the cam 44 rotates or reciprocates around its axis, and the valve stem 3, pushed by the contour of the cam 44, performs linear reciprocating motion according to a preset pattern. The spring 43 allows the cam 44 to automatically return to its original position after moving along a predetermined path, ensuring that the surfaces of the cam 44 and the valve stem 3 always have appropriate contact force, thereby ensuring smooth movement and torque transmission, while reducing the impact or vibration caused by the movement of the cam 44.

[0030] In one feasible embodiment, the valve stem 3 is provided with a roller 34, which abuts against the cam 44. This embodiment transforms the friction between the cam 44 and the valve stem 3 into rolling friction, improving the smoothness of movement.

[0031] In one feasible embodiment, the tank 1 is provided with a protective cover 11, which is used to cover the drive structure 4. Since the feeder is in a harsh environment (humid and highly corrosive), the protective cover 11 effectively shields the drive structure 4, preventing it from being corroded by moisture and pollutants.

[0032] In one feasible implementation, the end face of the tank body 1 is provided with a liquid inlet 12, which is used to add liquid into the tank body 1.

[0033] In one feasible embodiment, the lower end face of both the tank 1 and the liquid guide tube 2 is conical. In this embodiment, the conical surface facilitates complete emptying of the liquid from the tank 1. Because the bottom is conical, the liquid can flow along the bottom towards the center, facilitating more thorough drainage and reducing residue.

[0034] In one feasible implementation, the lower end of the liquid guide tube 2 is connected to a connecting pipe 5, and a valve assembly 6 is provided on the connecting pipe 5. The valve assembly 6 is used to close and open the connecting pipe 5. Because the second chamber 23 has a large capacity and is connected to the first chamber 22, it is easily contaminated by external factors when administering the sustained-release emulsion, which may affect the effectiveness of the drug and even cause secondary contamination. Therefore, when it is not necessary to administer the drug at fixed times and in fixed quantities, the second chamber 23 is closed by the valve to maintain a clean internal environment.

[0035] In one feasible embodiment, the valve assembly 6 includes a valve plug 61 having a flow guide hole 611, and the valve plug 61 is rotatably connected to the connecting pipe 5 so that the flow guide hole 611 can open or close the connecting pipe 5.

[0036] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of the equivalent elements of the claims are intended to be included within this application.
