Description

Technical Field

[0001] This invention relates to the field of medicine dispenser technology, and more specifically to a medicine protection device for medicine dispensers. Background Technology

[0002] A pill dispenser is a manual tablet-splitting tool commonly used in homes or clinical settings. It is primarily used to precisely cut whole tablets into half-tablets, quarter-tablets, etc., according to the prescribed dosage. To facilitate the storage of the split tablets and prevent them from getting damp or spilling, existing pill dispensers are often equipped with a medicine protection device. A typical structure includes a storage box with compartments and an openable dust cover.

[0003] However, in actual use, the existing medicine protection device for dispensing medicines cannot simultaneously achieve automatic removal of medicine residue and independent storage of medicine tablets when dispensing different types of medicine tablets. This results in residual debris being mixed with subsequent medicine tablets, which not only causes cross-contamination and dosage inaccuracy, but also increases the risk of accidental ingestion due to the mixing of multiple medicines, making it difficult to meet the needs of safe and accurate home medication. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention solves the problem that existing drug protection devices cannot simultaneously achieve automatic removal of drug residue and independent storage of drug tablets when splitting multiple tablets, thus leading to cross-contamination, inaccurate dosage and the risk of accidental ingestion.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a medicine protection device for a dispensing device, comprising a protective shell and a storage box slidably disposed inside the protective shell. The storage box is divided into multiple independent storage chambers by partitions, and each storage chamber has a filter screen at its bottom. The protective shell forms a cavity for collecting medicine debris falling from the filter screen. The protective shell also has a debris cleaning mechanism, which is driven by a toothed plate fixedly disposed on one side of the storage box. When the storage box slides inside the protective shell, the toothed plate drives the debris cleaning mechanism to operate, simultaneously triggering an intermittent tapping action on the filter screen, causing medicine debris adhering to the storage chamber to fall through the filter screen into the cavity of the protective shell, where it is collected and removed by the debris cleaning mechanism.

[0006] Furthermore, the debris cleaning mechanism includes a drive wheel, which is rotatably mounted in a mounting groove on one side of the protective housing. Its shaft extends horizontally and is fixedly connected to a first bevel gear. The first bevel gear meshes with a second bevel gear, which is rotatably supported on the side wall of the protective housing. A first driven wheel is fixedly connected to the end of its shaft. The shaft of the first driven wheel is fixedly connected to a shaft rod, and the other end of the shaft rod is rotatably connected to the inner wall of the opposite side of the protective housing. Multiple eccentric cams are fixedly sleeved on the shaft rod. The position of each eccentric cam corresponds to the filter screen at the bottom of each receiving cavity, and is used to intermittently tap the filter screen during rotation.

[0007] Furthermore, the first driven wheel also meshes with the second driven wheel, which is rotatably mounted on the side wall of the protective housing. Its shaft is fixedly connected to one end of the lead screw. The lead screw is horizontally rotatably mounted in a fixed sealing cover inside the protective housing. A through hole is provided at the bottom of the sealing cover. The upper end of the strip brush plate passes through the through hole and slides inside the sealing cover, and is threadedly engaged with the lead screw. The lower end of the strip brush plate is attached to the bottom wall of the protective housing, and is used to reciprocate under the drive of the lead screw to clean up the accumulated drug debris at the bottom.

[0008] Furthermore, the storage box is fixedly provided with protrusions on both the left and right sides, and the protrusions are slidably engaged in the slides opened on the inner walls of both sides of the protective shell to guide the storage box to slide smoothly in the horizontal direction.

[0009] Furthermore, several vertically arranged limiting grooves are provided on both outer walls of the storage box, and a sliding plate is provided above the boss. The sliding plate is slidably connected to the limiting grooves and connected to the boss through several elastic elements. The upper surface of the sliding plate is provided with multiple arc-shaped protrusions, which cooperate with the arc grooves opened on the upper wall of the slide to generate periodic undulations during the sliding of the storage box, thereby assisting in triggering the vibration of the filter.

[0010] Furthermore, the upper part of the storage box is hinged with multiple dust covers, each dust cover corresponding to a storage cavity, which is used to seal the opening of the storage cavity when not in the medication state to prevent dust from entering and tablets from spilling out.

[0011] Furthermore, a dispensing mechanism is detachably installed on one side of the protective shell. The dispensing mechanism includes a bracket, and a dispensing platform is hinged inside the bracket. The upper surface of the dispensing platform is provided with symmetrically arranged positioning plates for clamping the tablets and assisting in aligning the cutting position.

[0012] Furthermore, guide rods are fixedly provided on both sides of the bracket, and sealing end shells are slidably sleeved on the guide rods. A cutting blade is fixedly installed inside the sealing end shells, and a return spring is sleeved on the guide rod below the sealing end shells to automatically return the sealing end shells to their original position after being pressed.

[0013] Furthermore, the inner side of the bracket is symmetrically provided with elastic buckles, and one side of the protective shell is provided with a notch for installing the dispensing mechanism. The notch is provided with buckle grooves on both sides that match the elastic buckles. The dispensing mechanism can be quickly installed and removed by the snapping of the elastic buckles and the buckle grooves.

[0014] Furthermore, a support platform is fixedly provided at the rear end of the bracket, and the upper end surface of the support platform is in contact with the lower side of the dispensing table to provide stable support during the dispensing operation and prevent the dispensing table from overturning.

[0015] Beneficial effects 1. The technical solution provided by this invention transforms the sliding motion of the storage box into debris cleaning power. The toothed plate drives the eccentric cam to intermittently tap the filter screen, and in conjunction with the lead screw and strip brush plate, it automatically cleans the dust accumulated at the bottom. This achieves timely separation and centralized removal of residual debris after the tablets are divided. This design fundamentally solves the problem of cross-contamination between different batches or types of tablets caused by the retention of drug residue in traditional medicine dispensers, ensuring that the tablets used each time are in a clean state, and significantly improving the hygiene and safety of household medicine use.

[0016] 2. This invention adopts a multi-chamber, independently isolated storage structure, with each storage chamber corresponding to one type of medicine and equipped with a dedicated dust cover. This physically eliminates the risk of accidental ingestion caused by mixing different tablets. At the same time, because the debris is efficiently discharged and does not remain in the tablet storage area, the divided tablets are free of powder or particles, ensuring a high degree of consistency between the actual dosage and the prescribed dosage. Compared with existing protective devices that only provide simple compartments and cannot handle debris, this invention, through the synergistic design of mechanical self-cleaning and partition sealing, achieves for the first time a highly reliable drug protection mechanism that integrates cutting, cleaning, and storage without the need for electronic components or external energy.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] The present invention will be further described below with reference to embodiments.

[0022] See attached document Figure 1-9 A medicine protection device for a dispensing device is mainly used in home or community medical settings to safely, cleanly, and classify and store split tablets, while automatically removing medicine debris generated during the cutting process to prevent cross-contamination and dosage inaccuracies.

[0023] The device mainly includes a protective outer shell 1 and a storage box 2 that slides inside it.

[0024] The protective shell 1 is an integral closed shell with a bottom cavity inside, which is used to temporarily collect and store medicine debris falling from the storage box 2. To facilitate regular cleaning of accumulated dust, powder outlets are provided on both the left and right side walls of the protective shell 1. The powder outlets are located in the bottom area of ​​the cavity and are rectangular through holes. In the non-cleaning state, the powder outlets are fitted with removable sealing plugs. The sealing plugs are made of silicone or soft plastic and have good airtightness and easy insertion and removal. They can effectively prevent external dust from entering and can be quickly pulled out to discharge accumulated medicine powder when needed.

[0025] The storage box 2 is horizontally slidably disposed inside the protective shell 1. Its interior is divided into multiple independent storage compartments by vertical partitions, each of which is used to store a type of pre-cut tablet.

[0026] like Figure 6 As shown, each storage cavity is equipped with a filter screen 21 at the bottom. The filter screen 21 is woven from stainless steel wire or food-grade plastic with a mesh size of less than 0.5mm, allowing fine debris to pass through, but effectively supporting whole or half tablets.

[0027] To achieve automatic debris removal, a debris cleaning mechanism is provided inside the protective shell 1. This debris cleaning mechanism is driven by a toothed plate 27 fixedly installed on one side of the storage box 2. When the user pulls out or pushes the storage box 2 in, the toothed plate 27 moves accordingly, thereby driving the debris cleaning mechanism to operate.

[0028] Specifically, refer to Figure 4 and Figure 5 The debris cleaning mechanism includes a drive wheel 3, which is rotatably installed in the mounting groove 14 opened on the right side wall of the protective housing 1. Its shaft extends horizontally and is fixedly connected to a first bevel gear 31.

[0029] The first bevel gear 31 meshes with the vertically arranged second bevel gear 32. The second bevel gear 32 is rotatably supported on the side wall of the protective shell 1 by bearings. The upper end of the bevel gear 32 is fixedly connected to the first driven wheel 33. One end of the shaft of the first driven wheel 33 is fixedly connected to the shaft 34. The shaft 34 passes through the interior of the protective shell 1 laterally and is rotatably connected to the left inner wall by bearings. Multiple eccentric cams 35 are fixedly sleeved on the shaft 34. The position of each eccentric cam 35 is directly opposite the filter screen 21 at the bottom of each storage cavity.

[0030] When the shaft 34 rotates, the protruding part of the eccentric cam 35 periodically pushes the lower surface of the filter screen 21 upward, causing it to vibrate slightly, thereby shaking off the debris attached to the tablet or cavity wall, which then falls into the cavity below through the filter screen 21.

[0031] Furthermore, the first driven wheel 33 also meshes with the second driven wheel 36, which is also rotatably mounted on the side wall of the protective housing 1. Its shaft is fixedly connected to one end of the lead screw 37, which is horizontally positioned inside the sealing cover 13 fixed at the bottom of the protective housing 1.

[0032] The sealing cover 13 is a long, narrow, enclosed cavity with a through hole at the bottom. The upper end of the strip brush plate 38 passes through the through hole and slides inside the sealing cover 13, and is threadedly engaged with the lead screw 37. The lower end of the strip brush plate 38 extends out of the sealing cover 13 and fits tightly against the bottom wall of the protective shell 1.

[0033] When the lead screw 37 rotates, the strip brush plate 38 moves back and forth along the axial direction of the lead screw 37, sweeping the debris deposited at the bottom of the cavity toward the powder discharge port on either side for easy centralized cleaning.

[0034] To ensure that the storage box 2 slides smoothly, protrusions 22 are fixed on both its left and right sides, and the protrusions 22 slide in the slides 11 opened on the inner walls of both sides of the protective shell 1.

[0035] In addition, a sliding plate 23 is provided above the boss 22. The sliding plate 23 is slidably connected to the outer wall of the storage box 2 through a vertically arranged limiting groove 25, and is connected to the boss 22 through several elastic elements 26 (such as compression springs).

[0036] The upper surface of the slide plate 23 is provided with multiple arc-shaped protrusions 24, which cooperate with the arc grooves 12 opened on the upper wall of the slide rail 11. When the storage box 2 slides, the arc-shaped protrusions 24 slide along the arc grooves 12.

[0037] When the eccentric cam 35 strikes intermittently, the elastic element 26 causes the storage box 2 to move up and down, and then the elastic element 26 transmits the micro-vibration to the entire storage box 2, which helps the filter screen 21 shake off the debris.

[0038] Each storage compartment is hinged with a dust cover 28, which can be opened and closed independently to seal the compartment when not in use, preventing dust from entering, tablets from getting damp, or accidental spillage.

[0039] To achieve integrated cutting and storage, a dispensing mechanism is detachably installed on one side of the protective casing 1, as shown in the reference. Figure 2 and Figure 9The dispensing mechanism includes a support 4, which is fixed to the notch on the side wall of the protective shell 1 by a snap-fit ​​structure. Specifically, the support 4 has symmetrical elastic buckles 44 on the inner side, and the protective shell 1 has corresponding buckle grooves 15 on both sides of the notch. It can be quickly installed and removed by pressing. The notch is not only used to accommodate the dispensing mechanism, but also forms an open channel below it, so that the cut tablets can slide off the dispensing table 41 without obstruction and fall directly into the corresponding storage cavity in the storage box 2 inside the protective shell 1, ensuring that the tablets are transferred smoothly and avoiding jamming or spillage in the middle.

[0040] The support 4 has a dispensing table 41 hinged inside. The upper surface of the dispensing table 41 is provided with symmetrical positioning plates 42, which are used to hold the tablets and assist in aligning them with the cutting line.

[0041] The support platform 43 is fixed at the rear end of the bracket 4. Its upper surface is in contact with the lower side of the dispensing table 41 to limit the rotation angle of the dispensing table 41 and ensure stable operation.

[0042] Guide rods 45 are fixed on both sides of the bracket 4, and a sealing end shell 47 is slidably sleeved on them. A cutting blade 48 is fixedly installed inside the sealing end shell 47. Pressing the sealing end shell 47 can cause the cutting blade 48 to move down to complete the cutting. After releasing, the return spring 46 pushes the sealing end shell 47 to return to its original position automatically, realizing one-handed operation. During the cutting process, the sealing end shell 47 covers the tablet, forming a local closed space, which effectively prevents the powder from flying away and protects the tablet and the operating environment.

[0043] like Figure 9 As shown, after cutting, the user can flip the dispensing platform 41 forward so that its front end tilts downward, so that the divided tablets slide down the surface of the dispensing platform 41 and are directly introduced into the corresponding storage cavity inside the lower protective shell 1. In order to facilitate accurate dispensing, the front outlet position of the dispensing platform 41 is aligned with the opening of a certain storage cavity in the storage box 2. The user can select the corresponding storage cavity for dispensing according to the type of medicine being cut, so as to avoid mixing.

[0044] Once a storage chamber has finished storing tablets, the user can push the storage box 2 horizontally so that it slides along the slide 11 to move the adjacent empty storage chamber directly below the outlet of the dispensing station 41, so as to receive the next type of tablet. This design supports continuous and orderly processing of multiple drugs without changing containers or manually transferring tablets, effectively preventing cross-contamination between different drugs.

[0045] It is worth noting that the storage cavities are arranged at equal intervals along the sliding direction, and the center distance between adjacent storage cavities is equal to the distance from the outlet of the dispensing platform 41 to the sliding starting position of the storage box 2. That is, each time the storage box 2 is slid a fixed distance, the next storage cavity can be automatically aligned with the outlet of the dispensing platform 41.

[0046] In summary, during actual use, the user first installs the dispensing mechanism into the notch on the side wall of the protective shell 1 by using the elastic buckle 44 and the buckle groove 15, so that the front outlet of the dispensing table 41 is directly opposite the opening of the leftmost storage cavity in the storage box 2.

[0047] Subsequently, the tablets to be divided are placed on the dispensing platform 41 and held in place by the positioning plates 42 on both sides. The sealing end shell 47 is pressed down, which drives the cutting blade 48 to move down to complete the cutting. At this time, the sealing end shell 47 covers the tablet to prevent the powder from flying away. After being released, the reset spring 46 pushes the sealing end shell 47 to return to its original position automatically.

[0048] After cutting, the dispensing platform 41 is flipped forward so that it tilts downward around the hinge axis. The divided tablets slide down its surface and fall precisely into the currently aligned storage cavity through the open channel below the notch. The filter 21 at the bottom of the storage cavity supports the tablets, while fine debris passes through the filter 21 and falls into the bottom cavity of the protective shell 1.

[0049] When the tablets are stored, the user pushes the storage box 2 horizontally, causing it to slide one position to the right along the slide rail 11. At this time, the toothed plate 27 moves synchronously, driving the drive wheel 3 to rotate. This, in turn, drives the shaft 34 to rotate through the first bevel gear 31 and the second bevel gear 32, causing the eccentric cam 35 to periodically push the lower surface of each filter screen 21, generating vibration to shake off residual debris. At the same time, the first driven wheel 33 drives the lead screw 37 to rotate through the second driven wheel 36, causing the strip brush plate 38 to move back and forth, sweeping the dust accumulated at the bottom of the cavity towards the powder discharge port.

[0050] When the eccentric cam 35 pushes upward against the lower surface of the filter screen 21 during rotation, it applies an instantaneous upward impact force to the entire storage box 2. At this time, the elastic element 26 connected between the boss 22 and the slide plate 23 is compressed, absorbing part of the impact energy and playing a buffering role to prevent the tablets from bouncing, breaking, or shifting due to violent vibration. After the eccentric cam 35 rotates past its highest point, the elastic element 26 releases its stored energy, pushing the storage box 2 back to its original position smoothly, ensuring that the filter screen 21 returns to a horizontal state and providing a stable foundation for the next cleaning action. This mechanism not only protects the integrity of the tablets but also extends the service life of the device. At the same time, it allows the debris to more effectively detach from the tablet surface and pass through the filter screen 21 under controlled vibration, improving the cleaning efficiency.

[0051] In addition, the arc-shaped protrusion 24 on the slide plate 23 cooperates with the arc groove 12 on the upper wall of the slide rail 11 to provide guidance and limit during the horizontal sliding of the storage box 2, ensuring that its movement trajectory is smooth and does not deviate, thereby ensuring that the storage cavity can be accurately aligned with the outlet of the dispensing station 41 after each slide, while maintaining the vertical alignment accuracy between the filter screen 21 and the eccentric cam 35.

[0052] Once slid into place, the next empty storage chamber is aligned with the exit of the dispensing station 41. Users can then repeat the above operation to divide and store another type of tablet. Each storage chamber is independently sealed, and debris is removed in real time, effectively avoiding cross-contamination, product confusion, and dosage inaccuracy, thus achieving safe, accurate, and continuous management of multiple medications.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
