[0002] In the pharmaceutical, chemical, and medical industries, the quantitative addition of drugs or reagents is a fundamental and crucial operation. Traditional dosing devices often employ manual feeding methods or simple dosing structures.

[0003] The existing dosing equipment has the following problems during use:

[0004] Traditional dosing equipment mostly relies on manual judgment or simple containers, lacking effective volume or quality control devices, which leads to differences in the amount of medicine added each time, affecting the efficacy or experimental results. In addition, manual operation requires frequent opening and closing of containers, lacks automation support, is inefficient, and is prone to errors due to improper operation.

[0005] Therefore, we propose a quantitative dosing device. Utility Model Content

[0025] Example

[0026] Reference Figures 1 to 4 This embodiment provides a quantitative drug dispensing device that can achieve precise quantitative dispensing of drugs, which includes a storage component, a dispensing component, an adjustment component and a reset component.

[0027] Specifically, the storage component includes a drug storage tank 1 with a discharge port at the bottom. The drug storage tank 1 has sufficient capacity, and the discharge port at the bottom facilitates the rapid output of drugs, thereby improving the efficiency of drug dosing.

[0028] The metering component includes a partition 2, one end of which covers the outlet of the storage tank 1, and the other end of the partition 2 is connected to a metering cylinder 3. The bottom of the metering cylinder 3 has an opening and is covered by a cover plate 8. The end of the cover plate 8 facing the handle 10 is hinged to the outer wall of the metering cylinder 3. The bottom of the end of the cover plate 8 facing the handle 10 is an inclined surface. The inner bottom surface of the support frame 4 on the side away from the handle 10 is also an inclined surface. The hinged mechanism of the cover plate 8 enables gravity-driven self-opening. The partition 2 and the metering cylinder 3 enable the sealed transfer of medicine from the storage tank 1 to the metering cylinder 3, effectively controlling the amount of medicine added each time and ensuring stability and consistency. During the sliding process of the partition 2, it can block the outlet of the storage tank 1 to prevent accidental spillage of medicine and improve the safety of use.

[0029] The partition plate 2 is located below the discharge port of the medicine storage tank 1 and has a through hole 9. The bottom port of the through hole 9 is connected to a screw sleeve 17. The upper port of the metering cylinder 3 is threadedly connected to the screw sleeve 17, which facilitates the assembly and disassembly of the metering cylinder 3, the maintenance and replacement of the metering cylinder 3, and also facilitates cleaning.

[0030] The adjustment component includes guide rails 5 at both ends of the partition 2. The guide rails 5 are located below the discharge port of the storage tank 1 and are equipped with a support frame 4 for supporting the cover plate 8. The bottom of the guide rails 5 is located above the support frame 4 and is equipped with a limiting plate 11. The support frame 4 and the limiting plate 11 are connected vertically. The bottom cover plate 8 of the metering cylinder 3, the support frame 4, and the limiting plate 11 cooperate to form a closing and opening linkage mechanism, so that the medicine will not overflow or scatter during transportation, ensuring the cleanliness and controllability of the dosing process.

[0031] Both ends of the support frame 4 have longitudinally formed square grooves 13 on their top surfaces. The limiting plate 11 is located inside the square groove 13 and is slidably connected up and down. The outer surface of the limiting plate 11 is provided with scale lines 12. A screw 14 is rotatably provided on the outer wall of one end of the support frame 4, and a positioning rod 15 is connected to the outer wall of the other end of the support frame 4. A connecting sleeve 16 is provided on the outer wall of the guide rail 5 above the screw 14 and the positioning rod 15. The screw 14 and the connecting sleeve 16 are threaded together, and the positioning rod 15 and the connecting sleeve 16 are slidably connected. Through the cooperation of the screw 14, the positioning rod 15 and the connecting sleeve 16, the relative height between the limiting plate 11 and the support frame 4 can be adjusted, thereby adjusting the dosing capacity of the metering cylinder 3, adapting to various dosing needs and enhancing applicability.

[0032] The reset assembly includes a spring telescopic rod 6 disposed at the end of the partition 2. A handle 10 is disposed at the top of the end of the partition 2 away from the metering cylinder 3. A crossbar 7 is disposed at the end of the guide rail 5 away from the handle 10. The spring telescopic rod 6 is disposed between the end of the partition 2 and the outer wall of the crossbar 7. The automatic reset function of the device after the drug is added is realized through the cooperation of the spring telescopic rod 6 and the crossbar 7, which facilitates continuous operation.

[0033] In use, the partition 2 uses the metering cylinder 3 to draw medicine from the outlet of the medicine storage tank 1. The cover plate 8 at the bottom of the metering cylinder 3 covers the lower end of the metering cylinder 3 due to the limitation of the support frame 4. The handle 10 controls the partition 2 to slide along the guide rail 5. The partition 2 drives the metering cylinder 3 and its bottom cover plate 8 to detach from the support frame 4. At the same time, the top of the end of the partition 2 away from the metering cylinder 3 covers the outlet of the medicine storage tank 1 to prevent accidental overflow of the medicine inside the medicine storage tank 1. The cover plate 8 hinges and rotates under the action of gravity to open the metering cylinder 3. The medicine in the metering cylinder 3 falls into the container, realizing accurate metering of the medicine and ensuring that the medicine taken out each time is consistent. The spring telescopic rod 6 realizes the automatic reset of the partition 2, which is conducive to recycling.

[0034] In summary, the combination of partition 2 and metering cylinder 3 enables quantitative drug dispensing. The support frame 4 and cover plate 8 ensure the safety and controllability of the dispensing process. The adjusting component allows for flexible adjustment of the metering volume, making it suitable for different dosage requirements. The reset component enhances the automation level of the device.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
