[0030] The present invention will be further described in detail below in conjunction with specific embodiments, but the implementation methods of the present invention are not limited thereto.

[0031] In the patent entitled A medicine bottle cap (application number CN202421298940.9), the specific structure of the medicine bottle cap 910 can be found in the records of the above patent and the attached document of this application specification. Figure 1 and attached Figure 2, which includes two active parts, namely the first active part 911 and the second active part 912. The outer walls of the two active parts 911 and 912 are provided with tooth surfaces. The two active parts 911 and 912 control two material drop channels respectively. The bottoms of the two material drop channels are provided with a first discharge port 91c and a second discharge port 91d respectively. When preparing Chinese medicine granules, it is possible to choose to let the two active parts rotate at the same time or only let one of the active parts rotate. When the two active parts rotate at the same time, the two discharge ports will drop medicine at the same time. When only one active part rotates, only one discharge port will drop medicine.

[0032] In order to cooperate with the bottle cap 910, when preparing Chinese medicine particles, both the double discharge ports can be selected to drop the medicine at the same time, or the single discharge port can be selected to drop the medicine. The utility model specifically provides a dispensing unit, see Figures 1 to 5 The adjusting unit includes: a placing box 100, two sets of driving components 200 and a frame 300.

[0033] See also Figure 1 and Figure 2 The placement box 100 has a first cavity 110, the top of the first cavity 110 has an opening to allow the bottle cap of the medicine bottle to be inserted therein, and the bottom of the first cavity 110 is provided with two medicine discharge holes 120, and the two medicine discharge holes 120 respectively correspond to the discharge ports at the bottom of the two material discharge channels arranged in the bottle cap 910.

[0034] See also Figures 1 to 3 The two groups of driving components 200 are respectively arranged on both sides of the placing box 100, and the two groups of driving components 200 are suitable for respectively controlling the two dropping channels of the bottle cap 910, so that the discharge ports at the bottom of the two dropping channels can drop medicine at the same time or selectively drop medicine one by one.

[0035] See also Figures 1 to 3 The placement box 100 and the two sets of driving components 200 are installed on the frame 300.

[0036] Since the outer walls of the first active member 911 and the second active member 912 in the medicine bottle cap 910 of the application number CN202421298940.9 are both provided with tooth surfaces, in order to cooperate with the tooth surfaces to drive the first active member 911 and the second active member 912 to rotate, the driving assembly 200 at least includes a motor 210 and a first gear 220.

[0037] See also Figures 1 to 3, the motor 210 is mounted on the frame 300. The first gear 220 is driven to rotate directly or indirectly by the motor 210, and at least part of the teeth of the first gear 220 are located in the first cavity 110, so that after the bottle cap 910 is inserted into the first cavity 110, it can mesh with the tooth surfaces of the outer walls of the first active member 911 and the second active member 912 of the bottle cap 910, so as to achieve the purpose of driving the first active member 911 and the second active member 912 to rotate.

[0038] In some embodiments, the first gear 220 is indirectly driven to rotate by the motor 210. Figures 1 to 3 The driving assembly 200 further includes a second gear 230 , which is connected to the output shaft of the motor 210 , and the second gear 230 is meshed with the first gear 220 , and the first gear 220 is rotatably mounted on the frame 300 .

[0039] Preferably, see Figure 1 The first gear 220 is rotatably mounted on the outside of the placement box 100 , and a portion of the teeth of the first gear 220 is placed into the first cavity 110 through a notch 130 opened on the side wall of the placement box 100 .

[0040] Preferably, see Figure 1 , the number of teeth of the second gear 230 is much less than the number of teeth of the first gear 220.

[0041] Therefore, when the bottle cap 910 of the above patent is inserted into the first cavity 110 of the placing box 100, the first active member 911 and the second active member 912 are respectively meshed with the two first gears 220. At this time, if the two motors 210 are started at the same time, the first active member 911 and the second active member 912 can be driven to rotate simultaneously through the two first gears 220, so that the two discharge ports 91c and 91d of the bottle cap 910 can drop medicine at the same time. If only one of the motors 210 is started, the first active member 911 or the second active member 912 can be driven to rotate through one of the first gears 220, so that medicine can drop from one of the discharge ports 91c / 91d of the bottle cap 910.

[0042] Among them, in the bottle cap 910 of the above patent, the rotation angle of the first active member 911 or the second active member 912 controls the amount of medicine dropped from the bottle cap 910 (for the specific principle, see the patent with application number CN202421298940.9). Therefore, in the present utility model, the rotation angle of the output shaft of the motor 210 can be controlled to control the rotation angle of the first active member 911 or the second active member 912, thereby changing the amount of medicine dropped from the first discharge port 91c or the second discharge port 91d of the bottle cap 910.

[0043] In order to position the position angles of the first active member 911 and the second active member 912 inserted into the first cavity 110 so that the first active member 911 and the second active member 912 can only be inserted into the first cavity 110 at the initial position angles, in some embodiments, the utility model further makes the following arrangements.

[0044] For details, see Figure 5 The outer surface of the first gear 220 forms a positioning structure 221 with a shape different from that of the teeth between two adjacent teeth. Preferably, the positioning structure 221 is a bar-shaped block structure with a height substantially equal to that of the teeth. Figure 5 In the bottle cap 910 designed by the applicant, the tooth surfaces of the outer walls of the two active parts 911 and 912 are respectively formed with a positioning notch that matches the positioning structures 221 of the two first gears 220, namely the first positioning notch 9111 and the second positioning notch 9121. The first positioning notch 9111 and the second positioning notch 9121 are both roughly located in the middle of their respective tooth surfaces.

[0045] See also Figure 2 When the first active member 911 and the second active member 912 are both in the initial position, the first positioning notch 9111 and the second positioning notch 9121 are located at the left and right sides of the bottle cap 910, respectively. Figure 5 When the two first gears 220 are both at the zero position, the positioning structures 221 of the two first gears 220 are respectively rotated to the positions where the distance between them is the shortest and they are facing each other.

[0046] In order to detect the position angles of the two first gears 220 and determine whether the two positioning structures 221 have rotated to the positions that are closest to each other and face each other, in a more preferred embodiment, the following settings are also made.

[0047] For details, see Figure 1 , Figure 2 , Figure 3 as well as Figure 5 The adjusting unit further includes two first sensors 400 , which are respectively arranged corresponding to the two first gears 220 and fixed on the frame 300 , and are respectively used to detect whether the two first gears 220 are at the zero position.

[0048] Preferably, the first sensor 400 is a Hall sensor, and a magnet is provided at a corresponding position of the first gear 220. The Hall sensor determines whether the first gear 220 rotates to the zero position by sensing the magnet.

[0049] Thus, before the bottle cap 910 is inserted into the first cavity 110, the two motors 210 drive the two first gears 220 to rotate respectively, and the two first sensors 400 respectively detect whether the two first gears 220 rotate to the zero position. Once the rotation to the zero position is detected, the two motors 210 stop working. At this time, the positioning structures 221 of the two first gears 220 are at the closest and opposite positions, see Figure 5 . Afterwards, when inserting the bottle cap 910, the first active member 911 and the second active member 912 of the bottle cap 910 can only be inserted at the angle of the initial position, that is, only when the two first active members 911 and 912 are both in the initial position and the two positioning notches 9111 and 9121 are respectively located on the left and right sides of the bottle cap 910, can the bottle cap 910 be smoothly inserted into the first cavity 110. Otherwise, as long as one of the active members is not in the initial position, the positioning notch of the active member will be misaligned with the corresponding positioning structure 221, thereby causing the bottle cap 910 to be unable to be inserted into the first cavity 110. Therefore, the above structure ensures that after the bottle cap 910 is inserted into the first cavity 110, the two active members 911 and 912 are both in the initial position, so when the first gear 220 subsequently drives the first active member 911 or the second active member 912 to rotate, it can be ensured that the rotation starts from the initial position as the starting point, and then the amount of medicine dropped can be accurately controlled. That is to say, if the first active member 911 or the second active member 912 rotates unexpectedly before the bottle cap 910 is inserted into the first cavity 110, resulting in it not being in the initial position, then when the bottle cap 910 is subsequently inserted, the bottle cap 910 cannot be inserted into the first cavity 110, thereby avoiding the situation where the actual amount of medicine dropped is inconsistent with the expected amount of medicine dropped when the first gear 220 drives the first active member 911 or the second active member 912 to rotate.

[0050] In some embodiments, see Figure 1 The dispensing unit further includes a second sensor 500, which is disposed at the side of the placing box 100 and is used to detect whether the bottle cap 910 is inserted into the first cavity 110 and whether the insertion position is in place.

[0051] Preferably, the second sensor 500 is an infrared reflection sensor, which is fixed on the outside of the placement box 100. The side wall of the placement box 100 begins to have an avoidance hole corresponding to the infrared reflection sensor, so that the infrared reflection sensor can detect through the avoidance hole whether the bottle cap 910 is inserted into the first cavity 110 and whether the insertion position is in place.

[0052] In some embodiments, see Figure 1 and Figure 4, the adjustment unit also includes an elastic limiting component 600, and the elastic limiting component 600 includes a top ball 610 and an elastic member 620. The front end of the top ball 610 is a hemispherical structure, and the rear end is connected to or abuts against the elastic member 620. The elastic member 620 is relatively fixed to the placement box 100. Wherein, when in a natural state, under the action of the elastic member 620, the front end of the top ball 610 penetrates the side wall of the placement box 100 and is placed in the first cavity 110; when the elastic member 620 is compressed, the front end of the top ball 610 can retreat from the first cavity 110 to hide in the wall of the placement box 100.

[0053] Preferably, the number of the elastic limiting components 600 is four, of which two elastic limiting components 600 are arranged at a certain distance on the front side of the placement box 100, and the other two elastic limiting components 600 are also arranged at a certain distance on the rear side of the placement box 100. The elastic member 620 is a U-shaped spring sheet, which is fixed in a strip square groove 630, and the strip square groove 630 is fixed on the outer wall of the placement box 100.

[0054] Thus, when the bottle cap 910 is inserted into the first cavity 110, the outer wall of the bottle cap 910 will squeeze each top bead 610, causing each top bead 610 to retract. When the bottle cap 910 is inserted into place, each top bead 610 will extend again under the action of the corresponding elastic member 620, and the step surface of the bottle cap 910 will be stuck (see Figure 4 and Figure 5 ) to prevent the bottle cap 910 from moving upward when the first active member 911 or the second active member 912 is subsequently rotated.

[0055] In some embodiments, the side wall of the placement box 100 is provided with a positioning boss 140 and / or a positioning groove for limiting the bottle cap inserted into the first cavity 110 so that the bottle cap maintains a fixed position.

[0056] Preferably, see Figure 1 The inner walls of the front and rear sides of the placing box 100 are each provided with a positioning boss 140 extending along the height direction of the placing box 100. Figure 1 In the bottle cap 910 designed by the applicant, a vertical groove 913 matching the positioning boss 140 is respectively provided on the front and rear sides of the bottle cap 910 .

[0057] Thus, when the bottle cap 910 is inserted into the first cavity 110, the two positioning bosses 140 will be respectively embedded in the two vertical grooves 913 (see Figure 4 ), so that the position of the bottle cap 910 in the first cavity 110 is stabilized, and the bottle cap 910 is prevented from shaking when the first active member 911 or the second active member 912 is rotated.

[0058] In some embodiments, see Figure 3 , the bottom area of ​​the placing box 100 is provided with an RFID sensor 710. The RFID sensor 710 is used to identify the RFID tag provided on the bottle cap 910, and the RFID tag records information such as the drug category. Therefore, the RFID sensor 710 can determine whether the medicine bottle inserted in the first cavity 110 is a drug of a predetermined category by reading the RFID tag, thereby preventing the wrong drug from being inserted in the first cavity 110.

[0059] Preferably, the RFID sensor 710 is covered on the bottom of the placement box 100 through a detachable cover plate 720. The RFID sensor 710 can also be electrically connected or communicatively connected to an alarm device. If the RFID sensor 710 detects that the medicine bottle inserted in the first cavity 110 is inconsistent with the predetermined medicine bottle, an alarm sound and / or an alarm light can be emitted through the alarm device to alert the staff.

[0060] In summary, it can be seen that the dispensing unit of the utility model achieves the purpose of working in coordination with the medicine bottle cap previously designed by the applicant. By controlling the two motors 210 to rotate simultaneously or selectively, the two discharge ports of the medicine bottle cap inserted in the placement box 100 can drop medicine at the same time or selectively drop medicine. By controlling the rotation angle of the motor 210, the amount of medicine dropped can be controlled.

[0061] In addition, the utility model also provides a Chinese medicine formula granule dispensing device, which is provided with the above-mentioned dispensing unit.

[0062] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
