Some embodiments of the present aspect will be described in more detail below with reference to the accompanying drawings to enable those skilled in the art to practice the invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. These embodiments do not limit the invention, but the invention is only limited by the appended claims. Furthermore, the terminology used in the detailed description of the particular embodiments illustrated in the accompanying drawings is not intended to be limiting of the invention.

The following description focuses primarily on embodiments of the invention applied to a dispenser, but it will be appreciated that the invention is not limited to these applications.

Referring to fig. 7 and 10, there are illustrated assembled perspective views of the tablet-dispensing device 1 of the present invention in use. Referring to fig. 6, it can be seen that the inner circumference of the upper part of the enclosing chamber 12 of the tablet-distribution device 1 is provided with an inner thread. This is provided in order to open the lid of the vial 2, securing its inverted knob to the opening of the packaging cavity 12 of the tablet-dispensing device 1. Thus, the space inside the medicine bottle 2 and the package cavity 12 of the tablet distribution device 1 form a closed communication space, preventing the tablets from absorbing moisture and getting damp.

With reference to figures 1, 2 and 3, the housing chamber 12 of the tablet-dispensing device 1 of the present invention is illustrated. The packaging cavity 12 is a cylinder with a top opening and a closed bottom, and the top opening is axially arranged along the solid cylinder 111, and an inner circumference of the top opening of the packaging cavity 12 is provided with an inner thread matched with the outer thread of the bottle opening of the medicine bottle 2. The diameter of the potting cavity 12 is set to just encase the rafters 112 and the solid cylinder 111, and the height of the potting cavity 12 is set to just encase the solid cylinder 111. In addition, the material of the packaging cavity 12 of the tablet dispensing device 1 of the present invention may be plastic, metal, etc. which are conventionally used in the art. Furthermore, in order to fix the tablet dispensing apparatus 1 of the present invention conveniently, the outer circumference of the packaging cavity 12 may be provided with a fixing mechanism. In an embodiment of the present invention, as shown in fig. 5, two magnets with opposite magnetic poles may be disposed on two sides of the package cavity 12. The shape of the package cavity 12 of the tablet distribution device 1 of the present invention may be determined according to actual production conditions, for example, the shape of the package cavity may be circular in inner cross section and square in outer cross section, as long as the inner cross section is circular. It should be noted that the diameter of the circumference of the opening of the packaging cavity 12 is made according to the diameter of the mouth of the medicine bottle 2. For example, the diameter of the mouth of a conventional medicine bottle is 2.6cm to 50cm, and thus a package cavity having a diameter slightly larger than 2.6cm to 50cm can be manufactured according to the diameter thereof, for example, the diameter of the package cavity 12 of the tablet dispensing apparatus 1 of the present invention can be 3cm, 4cm, 7cm, 10cm, 15cm, 25cm, 30cm, 35cm, 40cm, 45cm, and 50 cm. That is, the diameter of the package cavity 12 of the tablet-dispensing device 1 of the present invention may be made according to the vial of the particular drug.

Referring to fig. 5, 8, 9 and 10, a medicament leakage opening 121 of the enclosing chamber 12 of the tablet-distribution device 1 is illustrated, which is used to allow a tablet to leak out of the enclosing chamber 12. The bottom of the packaging cavity 12 is provided with a medicine leakage opening 121 along the bottom round edge, the shape of the cross section of the medicine distribution groove 113 is the same, and when the tablet distribution device is static, the medicine leakage opening 121 is communicated with the medicine distribution groove 113. And, the medicine leakage opening 121 of the packaging cavity 12 is arranged below the tablet flow distribution plate 13, so that the tablet flow distribution plate 13 can distribute the tablet into an upper part and a lower part, and the number B of tablets can be output only once below, for example, one tablet leaks from the medicine leakage opening 121.

Referring to fig. 1, 2, 3 and 6, a tablet distribution plate 13 of the tablet distribution device 1 of the present invention is illustrated. As can be seen from the figure, the tablet flow distribution plate 13 of the present invention is vertically disposed on the inner circumference of the packaging cavity 12, and can also pass through the outer circumference of the packaging cavity 12, and stagger with the fixing mechanism of the packaging cavity 12, thereby facilitating the performance of the functions thereof.

Referring to fig. 1, 2 and 3, the driving mechanism 14 of the tablet distribution device 1 of the present invention is explained. The drive mechanism 14 is used to drive the tablet dispensing mechanism 11, while the drive mechanism 14 is powered by a motor drive. The driving mechanism 14 includes a driving gear 141 and a driving shaft 142, the driving shaft 142 of the driving gear 141 is fixed to the solid cylinder 111 through the bottom of the housing chamber 12 and is coaxial with the solid cylinder 111, and the motor has a motor shaft 15 engaged with the driving gear 141. As can be seen, the drive shaft 142 is centrally disposed at the bottom of the enclosure 12. The motor shaft 15 of the motor has teeth that mesh with the teeth of the driving gear 141 to thereby carry the driving gear 141. Meanwhile, the motor shaft 15 has a return spring, and after rotating a certain distance, it can return to an initial position for the next wheel driving.

Referring now to fig. 4, 5, 8 and 9, the tablet distribution plate 13 of the tablet distribution device 1 of the present invention will be further described. The tablet distribution plate 13 is vertically provided on a flat plate of the inner circumferential wall of the sealing chamber 12, and the flat plate is inserted into a predetermined gap between the upper projection 1121 and the lower projection 1122 and is provided directly above the medicine discharge port 121. The flat plate of the tablet splitter plate 13 is tangential to the circumference of the solid cylinder 111. The sectional area of the tablet flow distribution plate 13 is the same as that of the medicine leakage opening 121, that is, the tablet flow distribution plate 13 can only cover the section of one medicine distribution groove 113. It will be appreciated that the tablet splitter plate 13 is fixed to the inner circumference of the packaging chamber 12, but may also extend to the outer circumferential wall of the packaging chamber 12. When the tablet dispensing mechanism 11 is operated, it appears that the tablet distribution plate 13 separates the upper and

lower projections

1121 and 1122 of the tablet dispensing mechanism 11 because the flat plate of the tablet distribution plate 13 is inserted into the gap between the upper and

lower projections

1121 and 1122. Thus, the tablets entering the dispensing grooves 113 of the upper and

lower projections

1121 and 1122 are divided into upper and lower portions by the tablet distribution plate 13, and the number B of tablets to be dispensed per time from the dispensing port 121 can be controlled by controlling the height of the lower projection 1122 and the volume of the lower portion of the dispensing groove 113.

Referring now to figures 4, 5, 8, 9 and 10, the tablet dispensing mechanism 11 of the tablet-dispensing device 1 of the present invention is illustrated. Tablet dispensing mechanism 11 includes a solid cylinder 111 and a plurality of strips of ribs 112 uniformly arranged on the surface of solid cylinder 111 from top to bottom along the axial direction of solid cylinder 111, wherein ribs 112 are cut into upper ribs 1121 and lower ribs 1122 along the radial direction of solid cylinder 111, and a medicine groove 113 is formed between adjacent ribs 112. The thickness between the upper protruding rafter 1121 and the lower protruding rafter 1122 is substantially the same as the thickness of the flat plate of the tablet distribution plate 3. As can be seen from the figure, the cross section of the convex rafter 112 may be a sector, but may be other shapes, and the cross section of the dispensing chute 113 is correspondingly triangular. It should be noted that the top of the upper protruding rafters 1121 is a rounded curved surface protruding upward. So that the tablets can smoothly drop from the top of the upper protruding rafters 1121 into the dispensing chute 113. Meanwhile, the top of the solid cylinder 111 is a protruding cone. Such that the tablets, after falling from the vial 2 into the enclosure 12, slide smoothly from the top of the solid cylinder 111 to the upper lip 1121.

Referring now to figures 8, 9 and 10, the method of use of the tablet-dispensing device 1 of the present invention will be described in terms of its operation for accurate dispensing. The process is divided into three procedures of calculating parameters, splitting tablets and mechanically splitting medicines.

It should be noted that the tablet splitting device of the present invention is designed for a specific type of medicine. In one aspect, the tablets are preferably dispensed individually. On the other hand, the tablets are different in size and shape, a single tablet distribution device can only distribute one tablet at a time, and parameters need to be recalculated according to the sizes of different tablets each time, so that accurate distribution is achieved. However, the tablet distribution device of the present invention can be used in a plurality of ways, and a plurality of tablets are prepared for a plurality of types respectively. Therefore, the medicine can be effectively, safely and conveniently distributed, and multiple medicines can be taken at the same time.

The calculation parameters will now be described in detail. First, the cap of the medicine bottle 2 is unscrewed and the mouth is opened. The mouth of the medicine bottle 2 has an external thread. With 2 back-offs of medicine bottle the utility model discloses a tablet dispensing device 1's encapsulation cavity 12, with the internal thread spiral shell of encapsulation cavity 12 upper portion opening part closes to fix medicine bottle 2 the utility model discloses a tablet dispensing device 1. Then, the tablet falls into the sealing cavity 12 along the opening of the bottle 2, and is divided by the protruding cone at the top of the solid cylinder 111, and then, the tablet contacts the curved top of the upper protruding rafter 1121, and slides down to the dispensing groove 113. At this time, each tablet distributing groove 113 is filled with tablets, and the upper part of the tablet distributing groove 113 partitioned by the tablet distributing plate 13 is filled with tablets only, and the lower part of the tablet distributing groove 113 is communicated with the tablet leaking port, and no tablet exists. The tablet diversion is complete. The specific process is as follows: a number of tablets to be dispensed are dosed into the tablet-distribution device 1. These tablets are not all tablets to be dispensed, but a part thereof, and are for calculating the number of tablets to be dispensed from the medicine dispensing port 121 at a single time. And (5) turning on the motor, and recording the time I of single tablet output when the motor drives the convex rafter 112 to rotate horizontally and just passes through the medicine leakage opening 121. This time is the time when the protruding rafter 112 just passes over one drug leaking opening 121, so that the number of tablets leaking out of the drug leaking opening 121 at one time can be correspondingly known. The number B of tablets per discharge leaked from the medicine leakage port 121 is counted, and the total discharge time T required for the motor drive mechanism 14 to complete medicine dispensing is calculated according to the following equation:

full output time T = single output tablet time I × total number of tablets required to be dispensed a/single output tablet number B.

The tablet splitting process will now be described in detail. The cap of the vial 2 is opened so that all the tablets can enter the package chamber 12 of the tablet splitting apparatus. The medicine bottle 2 is turned upside down to the internal thread of the top opening of the packaging shell 12, and then is shunted by each convex rafter 112 to enter each medicine distributing groove 113 to wait for mechanical medicine distribution and complete the medicine distribution. It should be noted that when the tablet dispensing apparatus 1 of the present invention is at rest, the protruding rafter 112 is just adjacent to and completely staggered with respect to the dispensing chute 113. Thus, each cycle of operation causes only one lower lip 1122 to pass through the dispensing opening 121 and the next dispensing slot 113 of that lower lip 1122 is aligned with the dispensing opening 121, and a tablet is dispensed therefrom. Such that the rafter 112 is operated to deliver the maximum number of tablets during a given single tablet delivery time I.

The mechanical dispensing will now be described in detail. When the motor is turned on, the driving shaft 142 drives the driving gear 141 to rotate the convex beam 112, and the tablets in the respective tablet dispensing grooves 113 rotate accordingly. After the driving mechanism 14 starts to drive, the convex beam 112 starts to run clockwise or counterclockwise, and the tablet splitting plate 13 splits the tablet in the tablet splitting groove 113 communicated with the tablet leaking port 121 into an upper part and a lower part. When the medicine distributing groove 113 is aligned with the medicine leaking opening 121, the tablets leak from the medicine leaking opening 121, and one operation cycle is completed. Thus, when the dispensing groove 113 is the same as the medicine leakage opening 121, the tablet leaks out from the medicine leakage opening 121, and one-time tablet output is completed. Such a tablet output process is continuously circulated as the motor is continuously rotated. When the driving mechanism 14 is driven for the entire discharge time T, a required number of tablets are discharged from the tablet discharge port 121, and the discharge of the tablets is completed.

Obviously, modifications and/or additions of parts may be made to the dispensing device as described heretofore, without departing from the field and scope of the present invention.

It should also be clear that, although the present invention has been described with reference to some specific examples, a person of skill in the art shall certainly be able to achieve many other equivalent forms of dispensing device, including the corresponding features as set forth in the claims and hence all coming within the field of protection defined thereby.
