DETAILED DESCRIPTION

[0042] In order to make the skilled in the art better understand the technical scheme of the utility model, the utility model is further explained in detail below in combination with specific embodiments.

[0043] As Figures 1-8 The utility model discloses a medicine cover, including end cover 1 and threaded cover 2;The cover plate of end cover 1 is provided with at least one discharge hole one 3 along the circumference;Threaded cover 2 and end cover 1 fixed connection, the cover plate of threaded cover 2 is provided with at least one discharge hole two 4, and discharge hole two 4 and discharge hole one 3 are arranged in staggered arrangement;End cover 1 and threaded cover 2 have mounting gap 5 in axial and radial direction, and rotatable driving part 6 is arranged in mounting gap 5, and driving part 6 is provided with at least one discharge hole three 7, and driving part 6 has at least one preset position one and at least one preset position two on its rotating path;When driving part 6 rotates to preset position one, discharge hole three 7 and discharge hole one 3 are communicated, and are disconnected with discharge hole two 4, when driving part 6 rotates to preset position two, discharge hole three 7 and discharge hole one 3 are disconnected, and are communicated with discharge hole two 4;Still include stirring part 8, stirring part 8 and driving part 6 are connected, and stirring part 8 is located in the inside of threaded cover 2, and follows driving part 6 and rotates.

[0044] In the embodiment, the end cover 1 and the threaded cover 2 are fixedly connected fixed components, and the driving member 6 and the stirring member 8 are combined together into a moving component. In use, the position of the fixed component is determined, and the moving component moves relative to the fixed component by applying force to the driving member 6, so that the stirring member 8 rotates while the three discharge holes 7 have relative movement, thereby agitating the medicine in the threaded cover 2, and further improving the flowability of the medicine. Specifically, in the initial state, the medicine is located in the threaded cover 2. During the rotation of the driving member 6, the medicine is communicated between the first discharge hole 3 and the third discharge hole 7, so that the medicine enters the third discharge hole 7 and continues to rotate with the driving member 6. When the second discharge hole 4 and the third discharge hole 7 are communicated, the medicine in the third discharge hole 7 can fall out of the second discharge hole 4, thereby realizing the discharge of the medicine. Since the first discharge hole 3 and the second discharge hole 4 are arranged in a staggered manner, the flow of the medicine between the first discharge hole 3, the third discharge hole 7 and the second discharge hole 4 is intermittent, thereby maintaining the discharge accuracy of the medicine. When the discharge is insufficient at one time, the driving member 6 only needs to be continuously rotated, and the above process can be repeated. Based on this, in the embodiment, the depth of the third discharge hole 7 is greater than the thickness of the cover plate of the driving member 6. As shown in Figure 6 , a protruding block structure 9 is formed on the cover plate of the driving member 6, and the third discharge hole 7 is formed by opening a hole in the structure. At this time, a relatively large amount of medicine can be stored in the third discharge hole 7. Therefore, in a process requiring a large amount of discharge at one time, the process can be completed at one time. For a process requiring a small amount of discharge, the amount of medicine can be controlled by controlling the coverage area between the second discharge hole 4 and the third discharge hole 7. Further, since the formed adjacent third discharge holes 7 have a groove portion, in order to avoid the medicine remaining in the groove portion, the driving member 6 has a void filling body 10 for filling the groove portion. In the embodiment, the thickness of the cover plate of the driving member 6 and the thickness of the void filling body 10 are small, so that deformation can be well avoided during the injection molding process. For the medicine that may be left in the mounting gap 5 through the groove portion, it should be noted that when the third discharge hole 7 concentrates the medicine, the rotation of the driving member 6 will drive the medicine to move. At this time, there is continuous extrusion between the medicines, forming a pushing force along the rotation direction, so that the medicine may enter the groove portion along the mounting gap 5. At this time, the medicine entering the groove portion moves in the manner of the third discharge hole 7. Since the amount of medicine entering the groove portion is small, the force between the medicines is small. Therefore, even by reversing the rotation of the driving member 6, the medicine in the groove portion cannot be released, thereby causing waste of the medicine and possibly causing rotation jam.

[0045] As shown in Figure 3 , Figure 5 , Figure 8As shown, in this embodiment, a central post 11 extends from the middle of the end cap 1. The driving member 6 has an annular flange 12 for engaging with the central post 11. The threaded cap 2 is fitted inside the annular flange 12. The stirring member 8 is connected to the annular flange 12. The central post 11 serves as an assembly reference. After the driving member 6 is fitted onto the central post 11, it contacts the cover plate of the end cap 1 to achieve assembly positioning. Then, the threaded cap 2 is fitted inside the annular flange 12, and the cover plate of the threaded cap 2 contacts the cover plate of the end cap 1 to form assembly positioning. Next, the stirring member 8 is installed, connecting the stirring member 8 to the annular flange 12. Finally, the threaded cap 2 and the end cap 1 are fixed. Thus, when the driving member 6 is rotated, the stirring member 8 rotates accordingly, while the threaded cap 2 and the end cap 1 remain relatively stationary. The above method is only one assembly method adapted to the structure and process of this embodiment. In some embodiments, it can be directly formed by 3D printing, or it can be formed by half-body assembly. Therefore, different embodiments have different assembly and forming methods. For some other assembly methods, the threaded cap 2 and end cap 1 can be independently formed and assembled first, and then fixedly connected by ultrasonic welding technology. In this embodiment, as shown... Figure 7 As shown, it also includes a bracket 13, which has a mounting portion 14 connected to the intermediate column 11, and a plurality of mounting portions 15 inclined circumferentially along the mounting portion 14. The mounting portions 15 are connected to the cover plate of the threaded cover 2. Further, the mounting portion 14 is a cap structure, which is fastened to the end of the intermediate column 11. The plurality of mounting portions 15 are claw-shaped structures in a closed state relative to the mounting portion 14. According to the length and inclination angle of the mounting portions 15, the end cover 1 and the threaded cover 2 have an axial installation gap 5, and the radial installation gap 5 can be formed by the threaded cover 2 sleeved on the annular flange 12. This structure is suitable for a scheme in which the thread of the threaded cover 2 is set on the inside. In this case, it should be noted that the movement interference between the stirring element 8 and the mounting portions 15 should be avoided as much as possible, otherwise the stirring element 8 can only reciprocate within a limited range. When the thread of the threaded cap 2 is an external thread, the mounting part 2 15 is allowed to be connected to the inner wall of the threaded cap 2. At this time, it does not affect the threaded connection between the threaded cap 2 and the medicine bottle.

[0046] like Figure 3 As shown, in this embodiment, the stirring element 8 is sleeved on the outside of the intermediate column 11, and the stirring element 8 has axial freedom between the driving element 6 and the support 13. Figure 5As shown, in the drive member 6 and the stirring member 8, one is provided with a protrusion 16, and the other is provided with a recess 17 that mates with the protrusion. The stirring member 8 has multiple stirring parts radially distributed. The annular flange 12 is provided with the protrusion 16, and the stirring member 8 is provided with the recess 17 that mates with the protrusion 16. Therefore, when assembling the stirring member 8, installation can be easily achieved, thereby realizing the transmission connection. It should be understood that in order to stably achieve the rotation of the stirring member 8, the axial degree of freedom of the stirring member 8 between the drive member 6 and the bracket 13 should ensure that the stirring member 8 does not detach from the drive member 6. Assuming that the length of the protrusion 16 is equal to the length of the recess 17, then the degree of freedom should be less than the length of the protrusion 16. That is to say, in the axial direction, no matter what position the stirring member 8 is in, the protrusion 16 and the recess 17 always maintain a transmission engagement.

[0047] like Figure 3 As shown, in this embodiment, an annular guide member is provided between the end cap 1 and the driving member 6, and / or between the driving member 6 and the threaded cap 2. Specifically, an annular guide member is provided between the end cap 1 and the driving member 6, and between the driving member 6 and the threaded cap 2. The annular member is circular, which can improve the stability of rotation and ensure smoother movement of the rotating driving member 6. In addition, in order to ensure the rotation performance of the driving member 6, the driving member 6 and the intermediate column 11 should be in clearance fit. Therefore, the annular member can ensure the stability of the rotation path and avoid the skewing of the rotating driving member 6 during operation. At the same time, it can also avoid the misalignment between the first discharge hole 3 and the third discharge hole 7, and between the second discharge hole 4 and the third discharge hole 7, thereby reducing the discharge accuracy. The annular member is an annular groove and annular block member. Taking the end cap 1 and the driving member 6 as an example, the end cap 1 is provided with an annular groove, and the driving member 6 is provided with an annular block that fits into the annular groove. The same applies to the driving member 6 and the threaded cap 2.

[0048] In this embodiment, the mounting part 14 of the bracket 13 is provided with an identification part, which can be a QR code, barcode, NFC, RFID chip, etc. The identification part can identify the type of medicine and can be fixed to the mounting part 14 by means of snap-fit, adhesive, etc.

[0049] Based on the above embodiments, this embodiment also discloses a medicine bottle, which further includes a bottle body. The threaded cap 2 has internal or external threads, and the threaded cap 2 is threadedly connected to the mouth of the bottle body. The medicine bottle can be applied to a dispensing machine. Through a drive mechanism installed on the dispensing machine, the drive mechanism is connected to the drive component 6 to achieve rotation of the drive component 6. The drive mechanism can be a gear mechanism, rack mechanism, belt mechanism, push rod mechanism, cam mechanism, etc.

[0050] The above are only preferred embodiments of the present application, and it should be pointed out that the above preferred embodiments should not be regarded as a limitation to the present application, and the protection scope of the present application should be subject to the range defined by the claims. For ordinary skilled in the art, some improvements and refinements can be made without departing from the spirit and scope of the present application, and these improvements and refinements should also be regarded as the protection scope of the present application.
