Description

Technical Field

[0001] The utility model relates to the technical field of medicine production, in particular to a medicine bottle cap. Background Art

[0002] At present, a relatively automated dispensing method has been realized in the process of dispensing Chinese medicine granules. This type of automated dispensing method usually involves a special bottle cap with a metering function. The cap is installed behind the mouth of the medicine bottle and cooperates with corresponding automated equipment and programs to achieve automatic quantitative dispensing of medicine.

[0003] The applicant has previously designed a medicine bottle dispensing bottle cap and applied for a related patent, the application number of which is: CN202323452356.2. In order to ensure the efficiency of dispensing, the bottle cap in the patent is provided with two feeding holes and two discharging holes. When dispensing medicine, the two feeding holes are fed at the same time, and then the two discharging holes drop medicine at the same time. That is, when dispensing medicine, the bottle cap in the patent can only drop medicine at the same time from the two discharging holes, and it is not possible to choose to let only one of the discharging holes drop medicine while the other one does not drop medicine. This results in that the medicine can only be dispensed in two bags at a time, and the final number of bags can only be an even number. If the number of bags to be dispensed is an odd number, the corresponding number of bags cannot be accurately dispensed, and one more bag can only be dispensed, which causes unnecessary waste. For example, the doctor's prescription states that the method of taking the medicine is: take one bag at a time, three times a day, for a total of three days, that is, a total of nine bags of Chinese medicine need to be prepared, and the bottle cap of the above patent can only be dispensed in the manner of two bags at a time, so in the end only ten generations of Chinese medicine can be dispensed, resulting in one more bag being prepared, causing unnecessary waste.

[0004] In this regard, the applicant hopes to improve the bottle cap so that when preparing Chinese medicine, both discharge holes can be used to drop medicine at the same time, or only one discharge hole can be used to drop medicine while the other discharge hole is not used. In this way, when the number of bags to be prepared is an odd number, the corresponding number of bags can be accurately prepared, rather than preparing one more bag, which causes unnecessary waste. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a medicine bottle cap to meet the requirements of allowing medicine to be dropped from two discharge ports at the same time or allowing medicine to be dropped from only one discharge port while the other discharge port is not allowed to drop medicine.

[0006] The technical solution adopted by the utility model to solve the technical problem is: providing a medicine bottle cap, comprising a cap body, a first metering component and a second metering component;

[0007] A cover body, one side of the cover body is a feed side, and the other side is a discharge side, the feed side is provided with a first feed port and a second feed port, and the discharge side is provided with a first discharge port and a second discharge port; between the feed side and the discharge side, the cover body is further provided with a first annular placement area and a second annular placement area;

[0008] A first metering component, the first metering component is arranged in the first annular arrangement area, and the first metering component has a first metering space; the first metering component can rotate around a first axis in the first annular arrangement area independently of the second metering component, and during the rotation, the first metering space can be rotated to an area corresponding only to the first feed port, or an area corresponding only to the first discharge port;

[0009] A second metering component is arranged in the second annular arrangement area, and the second metering component has a second metering space; the second metering component can rotate around the second axis in the second annular arrangement area independently of the first metering component, and during the rotation, the second metering space can be rotated to an area corresponding only to the second feed port, or an area corresponding only to the second discharge port.

[0010] The bottle cap of the above technical solution has three ways of putting medicine, specifically:

[0011] The first method is that since the first metering component can rotate independently of the second metering component, the first metering component can be rotated independently to first rotate the first metering space to the area corresponding to the first feed port, so that the Chinese medicine particles in the medicine bottle enter the first metering space, and then rotate the first metering space to the area corresponding to the first discharge port, so that the medicine can be dropped into the first discharge port independently;

[0012] The second method is that since the second metering component can rotate independently of the first metering component, the second metering component can be rotated independently to first rotate the second metering space to the area corresponding to the second feed port so that the Chinese medicine particles in the medicine bottle enter the second metering space, and then rotate the second metering space to the area corresponding to the second discharge port, so that the medicine can be dropped into the second discharge port independently;

[0013] The third method is to rotate the first metering component and the second metering component at the same time, so that the first metering space and the second metering space are respectively transferred to the areas corresponding to the first feed port and the second feed port, so that the Chinese medicine particles in the medicine bottle enter the first metering space and the second metering space at the same time, and then the first metering space and the second metering space are respectively transferred to the areas corresponding to the first discharge port and the second discharge port, so that the medicine can be dropped into the first discharge port and the second discharge port at the same time.

[0014] It can be seen that when preparing Chinese medicine, the bottle cap of the utility model can allow the two discharge ports to drop medicine at the same time, or can choose to only allow one discharge port to drop medicine while the other discharge port does not drop medicine. When the number of bags of Chinese medicine to be prepared is an odd number, the bottle cap of the utility model can accurately prepare the corresponding number of bags, without preparing an extra bag as before, which would cause unnecessary waste.

[0015] Furthermore, the metering volume of the first metering space is variable, and the metering volume of the second metering space is also variable.

[0016] Usually, a dose of medicine contains multiple kinds of Chinese medicine particles. Therefore, in the process of automatic dispensing, multiple different Chinese medicine particles are usually put into one packaging bag. Different prescriptions have different types and proportions of medicine particles. Therefore, in order to make the bottle cap more applicable to the dispensing of different prescriptions, in the utility model, the metering volume size of the first metering space and the second metering space is specially designed to be variable, so that different metering volumes can be selected according to different prescriptions when dispensing, thereby achieving the purpose of adjustable proportions between medicine particles.

[0058] 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.

[0059] like Figures 1 to 8 As shown, the utility model provides a medicine bottle cap, which includes a cap body 100, a first metering component 200 and a second metering component 300.

[0060] One side of the cover body 100 is a feed side, and the other side is a discharge side. The feed side is provided with a first feed port 1a and a second feed port 1b, and the discharge side is provided with a first discharge port 1c and a second discharge port 1d. Figure 3and Figure 4 The cover body 100 is further provided with a first annular placement area 1e and a second annular placement area 1f between the feed side and the discharge side.

[0061] The first metering component 200 is arranged in the first annular placement area 1e, and the first metering component 200 has a first metering space 2a. The first metering component 200 can rotate around the first axis a in the first annular placement area 1e independently of the second metering component 300. During the rotation, the first metering space 2a can be rotated to an area corresponding only to the first feed port 1a, or an area corresponding only to the first discharge port 1c.

[0062] The second metering assembly 300 is arranged in the second annular arrangement area 1f, and the second metering assembly 300 has a second metering space 3a. The second metering assembly 300 can rotate around the second axis b in the second annular arrangement area 1f independently of the first metering assembly 200. During the rotation, the second metering space 3a can be rotated to the area corresponding only to the second feed port 1b, or the area corresponding only to the second discharge port 1d.

[0063] The first axis a and the second axis b mentioned above may be virtual axes rather than actual axes.

[0064] From the structural characteristics of the above bottle cap, it can be seen that the bottle cap has three ways of putting medicine, specifically:

[0065] The first method is that since the first metering component 200 can rotate independently of the second metering component 300, the first metering component 200 can be rotated independently to first rotate the first metering space 2a to the area corresponding to the first feed port 1a, so that the Chinese medicine particles in the medicine bottle enter the first metering space 2a, and then rotate the first metering space 2a to the area corresponding to the first discharge port 1c, so that the medicine can be dropped into the first discharge port 1c independently;

[0066] The second method is that since the second metering component 300 can rotate independently of the first metering component 200, the second metering component 300 can be rotated independently to first rotate the second metering space 3a to the area corresponding to the second feed port 1b so that the Chinese medicine particles in the medicine bottle enter the second metering space 3a, and then rotate the second metering space 3a to the area corresponding to the second discharge port 1d, so that the medicine can be dropped into the second discharge port 1d independently;

[0067] The third method is to rotate the first metering component and the second metering component at the same time, so that the first metering space 2a and the second metering space 3a are respectively rotated to the areas corresponding to the first feed port 1a and the second feed port 1b, so that the Chinese medicine particles in the medicine bottle enter the first metering space 2a and the second metering space 3a at the same time, and then the first metering space 2a and the second metering space 3a are respectively rotated to the areas corresponding to the first discharge port 1c and the second discharge port 1d, so that the medicine can be dropped into the first discharge port 1c and the second discharge port 1d at the same time.

[0068] It can be seen that when preparing Chinese medicine, the bottle cap of the utility model can allow the two discharge ports to drop medicine at the same time, or can choose to only allow one of the discharge ports to drop medicine while the other discharge port does not drop medicine.

[0069] When the number of bags of Chinese medicine to be prepared is an odd number, the bottle cap of the utility model can accurately prepare the corresponding number of bags. For example, in the prescription issued by the doctor, the way of taking medicine is: take one bag at a time, take it three times a day, and take it for a total of three days, that is, a total of nine bags of Chinese medicine need to be prepared. When the bottle cap of the utility model is used for preparation, the two discharge ports can be allowed to drop the medicine at the same time, and the medicine can be prepared in the manner of two bags at a time. After the fourth round of preparation, a total of eight bags have been prepared, and there is still one bag missing. In the last round, only one of the discharge ports can be allowed to drop the medicine, and the other discharge port can not drop the medicine, so that only one bag of Chinese medicine can be prepared. Finally, nine bags of Chinese medicine are prepared. Therefore, unlike the previous bottle cap, one more bag will be prepared in the last round, resulting in unnecessary waste.

[0070] Preferably, see Figure 3 The first feed port 1a and the first discharge port 1c are respectively located on two opposite sides of the first axis a, and the second feed port 1b and the second discharge port 1d are respectively located on two opposite sides of the second axis b.

[0071] Among them, when the first end face 2111 of the first arc-shaped groove 211 is within the feeding range of the first feed port 1a, the second end face 2112 is within the area between the first discharge port 1c and the first feed port 1a inside the first annular placement area 1e; at this time, even if the first passive part 220 fails, the first metering space 2a will not connect the first feed port 1a and the first discharge port 1c, so there will be no risk of drug leakage.

[0072] Similarly, when the third end face 3111 of the second arc-shaped groove 311 is within the feeding range of the second feed port 1b, the fourth end face 3112 is within the area between the second discharge port 1d and the second feed port 1b inside the second annular placement area 1f; at this time, even if the second passive component 320 fails, the second metering space 3a will not connect the second feed port 1b and the second discharge port 1d, and there will be no risk of drug leakage.

[0073] See also Figure 6 In the direction shown by the midpoint line, when feeding from the first feed port 1a, the drug particles enter from the first feed port 1a on the left side of the figure, and then enter the first metering space 2a. Subsequently, the first metering component 200 rotates around the first axis a, so that the first metering space 2a comes to the top of the first discharge port 1c, and then the drug particles fall from the first discharge port 1c on the right side of the figure.

[0074] See also Figure 8 In the direction shown by the midpoint line, when feeding from the second feed port 1b, the drug particles enter from the second feed port 1b on the right side of the figure, and then enter the second metering space 3a. Subsequently, the second metering component 300 rotates around the second axis b, so that the second metering space 3a comes to the top of the second discharge port 1d, and then the drug particles fall from the second discharge port 1d on the left side of the figure.

[0075] That is, in short, when the medicine is fed in from the left side, the medicine is dropped on the right side; when the medicine is fed in from the right side, the medicine is dropped on the left side; the medicine feeding and medicine dropping are respectively located on the left and right sides of the first axis a or the second axis b; among which, the first axis a and the second axis b can be understood as the center lines of two non-concentric but intersecting circles.

[0076] For ease of assembly, in a preferred embodiment, the cover body 100 of the present invention is split into three relatively independent parts. Specifically, the cover body 100 includes a first cover body 110 , a second cover body 120 and a middle cover body 130 .

[0077] The first cover body 110 is provided with an internal thread. When in use, the first cover body 110 can be connected to the bottle mouth of the medicine bottle through the internal thread. The first feed port 1a is provided on the first cover body 110.

[0078] The second cover body 120 is spaced apart from the first cover body 110 , and the second discharge port 1 d is disposed on the second cover body 120 .

[0079] The middle cover 130 is disposed between the first cover 110 and the second cover 120 .

[0080] The first cover body 110, the second cover body 120 and the middle cover body 130 can be connected and fixed by screws.

[0081] The first annular placement area 1e is an annular structure, formed by the area sandwiched by the first cover body 110 and the middle cover body 130, that is, Figure 4The first cover body 110 is provided with a first annular placement area upper groove 1e1, and the middle cover body 130 is provided with a first annular placement area lower groove 1e2. When the first cover body 110 and the middle cover body 130 are assembled together, the first annular placement area upper groove 1e1 and the first annular placement area lower groove 1e2 are spliced ​​together to form the first annular placement area 1e, see Figure 5 .

[0082] The second feed port 1b is formed by the first cover 110 and the middle cover 130, that is, Figure 4 The first cover body 110 is provided with a second feed inlet upper opening 1b1, and the middle cover body 130 is provided with a second feed inlet lower opening 1b2. When the first cover body 110 and the middle cover body 130 are assembled together, the second feed inlet upper opening 1b1 and the second feed inlet lower opening 1b2 are spliced ​​together to form the second feed inlet 1b, see Figure 5 .

[0083] The second annular placement area 1f is an annular structure, formed by the area sandwiched by the middle cover 130 and the second cover 120, that is, see Figure 4 The middle cover 130 is provided with a second annular placement area upper groove 1f1, and the second cover 120 is provided with a second annular placement area lower groove 1f2. When the middle cover 130 and the second cover 120 are assembled together, the second annular placement area upper groove 1f1 and the second annular placement area lower groove 1f2 are spliced ​​together to form the second annular placement area 1f, see Figure 5 .

[0084] The first discharge port 1c is formed by the middle cover 130 and the second cover 120, that is, Figure 4 The middle cover 130 is provided with a first discharge port upper opening 1c1, and the second cover 120 is provided with a first discharge port lower opening 1c2. When the middle cover 130 and the second cover 120 are assembled together, the first discharge port upper opening 1c1 and the first discharge port lower opening 1c2 are spliced ​​together to form the first discharge port 1c, see Figure 5 .

[0085] Preferably, see Figure 2 The second cover body 120 is internally provided with an RFID identification tag a1, which can realize the entry and reading of drug information, so that the mechanical device can accurately identify the drug information through the RFID identification tag a1 when grabbing the medicine bottle, thereby ensuring that the grabbed medicine bottle is the required medicine bottle and avoiding grabbing the wrong one.

[0086] Preferably, see Figure 2The second cover body 120 is provided with two limiting pin holes 121 for fixing the bottle cap on the outside. By inserting pins into the two limiting pin holes 121, the bottle cap can be positioned, which is convenient for quickly changing the state of the bottle cap, that is, it is ensured that the medicine bottle will not shake or shift when the external mechanical component drives the first active component 210 and / or the second active component 310 to rotate.

[0087] When assembling the bottle cap of the present invention, the second metering component 300 is placed in the lower groove 1f2 of the second annular placement area, the first metering component 200 is placed in the lower groove 1e2 of the first annular placement area, and then the first cover body 110, the second cover body 120, and the middle cover body 130 are connected and fixed together with screws.

[0088] Usually, a dose of medicine contains a variety of Chinese medicine particles. Therefore, in the process of automatic dispensing, a packaging bag usually contains a variety of different Chinese medicine particles, and different prescriptions have different types and ratios of drug particles. Therefore, in order to make the bottle cap more widely applicable to the dispensing of different prescriptions, in a preferred embodiment of the utility model, the metering volume size of the first metering space 2a and the second metering space 3a is deliberately designed to be variable, so that different metering volumes can be selected according to different prescriptions when dispensing, thereby achieving the purpose of adjustable ratios between drug particles.

[0089] That is, in a preferred embodiment of the utility model, the metering volume of the first metering space 2a is variable, and the metering volume of the second metering space 3a is also variable. It should be noted that the minimum metering volume of the first metering space 2a and the second metering space 3a can be zero, and the maximum metering volume can be set according to the actual situation; if the drug particles dropped with the maximum metering volume are still not enough for the dosage during one drug dropping process, the drug dropping can be repeated until the drug particles reach the required dosage. For example, if the metering volume of the first metering space 2a has been adjusted to the maximum value, but the drug particles dropped at one time can only reach 3 / 5 of the required amount, then the drug dropping can be repeated once more, but the dosage of the second drug dropping needs to be adjusted to 2 / 5 of the total required amount. After two drug drops, the total dosage of the drug particles dropped just reaches the required amount.

[0092] See also Figure 3 and Figure 8 The second metering component 300 includes a second active member 310 and a second passive member 320; the second active member 310 is an annular structure, the second active member 310 is arranged in the second annular arrangement area 1f and can rotate around the second axis b, the second active member 310 is provided with a second arc groove 311, and the two end faces of the second arc groove 311 in the arc direction are respectively a third end face 3111 and a fourth end face 3112; the second passive member 320 is arranged in the area enclosed by the second active member 310, the second passive member 320 is provided with a second dividing block 321, the second dividing block 321 is located in the second arc groove 311, and the second passive member 320 can rotate around the second axis b; the area between the third end face 3111 and the second dividing block 321 is the second metering space 3a, and the distance between the third end face 3111 and the second dividing block 321 is variable.

[0093] Furthermore, the limit positions of the first passive member 220 rotating around the first axis a are respectively a limit position I suitable for feeding the first metering space 2a and a limit position II suitable for discharging the first metering space 2a.

[0094] When the first passive member 220 rotates between the extreme position I and the extreme position II, it is driven to rotate by the first active member 210 .

[0095] Preferably, when the first passive member 220 rotates to the extreme position I, the side wall of the first partition block 221 close to the first end surface 2111 is aligned with the side wall of the first feed opening 1a, and the first partition block 221 is hidden under the first feed opening 1a. Fig.10 , the first active member 210 can continue to rotate in the direction of increasing the metering volume of the first metering space 2a, that is, at this time, the first active member 210 can rotate in the direction of increasing the metering volume of the first metering space 2a. Fig.10 The first active member 210 rotates counterclockwise in the middle, and the first passive member 220 will remain stationary due to the limit position I during the rotation. The first active member 210 can rotate to the maximum until the second end surface 2112 contacts the first partition block 221 (at this time, the metering volume of the first metering space 2a increases to the maximum value).

[0096] Preferably, when the first passive member 220 rotates to the extreme position II, the first partition block 221 is located above the first discharge port 1c (at this time, the side wall of the first partition block 221 may be aligned with the side wall of the first discharge port 1c, or may not be aligned, as long as the first discharge port 1c is not largely blocked). Fig.11 , the first active member 210 can continue to rotate in the direction of reducing the metering volume of the first metering space 2a, that is, at this time, the first active member 210 can rotate in the direction of reducing the metering volume of the first metering space 2a. Fig.11 The first active member 210 rotates clockwise in the middle, and the first passive member 220 will remain stationary due to the limit position II during the rotation. The first active member 210 can rotate to the maximum until the first end surface 2111 contacts the first partition block 221 (at this time, the metering volume of the first metering space 2a is reduced to zero).

[0097] Furthermore, the limit positions of the second passive member 320 rotating around the second axis b are respectively the limit position III suitable for feeding into the second metering space 3a and the limit position IV suitable for discharging from the second metering space 3a.

[0098] When the second passive member 320 rotates between the extreme position III and the extreme position IV, it is driven to rotate by the second active member 310 .

[0099] Preferably, when the second passive member 320 rotates to the extreme position III, the side wall of the second partition block 321 close to the third end surface 3111 is aligned with the side wall of the second feed opening 1b, and the second partition block 321 is hidden under the second feed opening 1b. Fig.12 , the second active member 310 can continue to rotate in the direction of increasing the metering volume of the second metering space 3a, that is, at this time, the second active member 310 can rotate in the direction of increasing the metering volume of the second metering space 3a. Fig.12 The second active member 310 rotates counterclockwise in the middle, and the second passive member 320 will remain stationary due to the limit position III during the rotation. The second active member 310 can rotate to the maximum until the fourth end face 3112 contacts the second partition block 321 (at this time, the metering volume of the second metering space 3a increases to the maximum value).

[0100] Preferably, when the second passive member 320 rotates to the extreme position IV, the second partition block 321 is located above the second discharge port 1d (at this time, the side wall of the second partition block 321 may be aligned with the side wall of the second discharge port 1d, or may not be aligned, as long as the second discharge port 1d is not largely blocked). Fig.13 , the second active member 310 can continue to rotate in the direction of reducing the metering volume of the second metering space 3a, that is, at this time, the second active member 310 can rotate in the direction of reducing the metering volume of the second metering space 3a. Fig.13 The second active member 310 rotates clockwise in the middle, and the second passive member 320 remains stationary due to the limit position IV during the rotation. The second active member 310 can rotate to the maximum until the third end surface 3111 contacts the second partition block 321 (at this time, the metering volume of the second metering space 3a is reduced to zero).

[0101] In order to limit the rotatable angle range of the first passive member 220, in a preferred embodiment, see Figure 7 The first passive member 220 is provided with a first limiting block 222 on its inner wall, and the first cover 110 is provided with a first limiting groove 111 at a position adapted to the first limiting block 222. When the first metering assembly 200 is assembled in the first annular placement area 1e, the first limiting block 222 is limited in the first limiting groove 111, and the first limiting block 222 can only rotate within the range limited by the first limiting groove 111, so as to ensure that the first passive member 220 can only rotate between the limit position I and the limit position II.

[0102] In order to limit the rotatable angle range of the second passive member 320, in a preferred embodiment, see Fig. 9 The inner wall of the second passive member 320 is provided with a second limit block 322, and the middle cover 130 is provided with a second limit groove 131 at a position adapted to the second limit block 322. When the second metering assembly 300 is assembled in the second annular placement area 1f, the second limit block 322 is confined in the second limit groove 131, and the second limit block 322 can only rotate within the range defined by the second limit groove 131, so as to ensure that the second passive member 320 can only rotate between the limit position III and the limit position IV.

[0103] In a preferred embodiment, see Figure 3The first metering component 200 also includes a first force-applying member 230, which is engaged in a first groove 212 preset on the inner wall of the first active member 210 and is relatively fixed to the first active member 210. The first force-applying member 230 applies an extrusion force to the outer wall of the first passive member 220, so that the first passive member 220 can rotate with the first active member 210 with the help of the friction force generated by the extrusion force, and the rotation range is between the extreme position I and the extreme position II.

[0104] Among them, the above-mentioned extrusion force is formed by the deformation of the first force-applying member 230 when it is engaged in the first groove 212. The strength of the extrusion force is moderate, and it can cause the first passive member 220 to rotate together with the first active member 210 when the first limit block 222 does not touch the side wall of the first limit groove 111. Once the first limit block 222 touches the side wall of the first limit groove 111, when the first active member 210 is turned with force, the first passive member 220 is restricted by the side wall of the first limit groove 111 and will not be able to continue to rotate together with the first active member 210. The first active member 210 can only rotate by itself (at this time, the first force-applying member 230 rotates together with the first active member 210 and slides relative to the first passive member 220), thereby changing the distance between the first end face 2111 and the first dividing block 221, and then changing the metering volume of the first metering space 2a.

[0105] Similarly, the second metering component 300 also includes a second force-applying member 330, which is engaged in a second groove 312 preset on the inner wall of the second active member 310 and is relatively fixed to the second active member 310. The second force-applying member 330 applies an extrusion force to the outer wall of the second passive member 320, so that the second passive member 320 can rotate with the second active member 310 with the help of the friction force generated by the extrusion force, and the rotation range is between the extreme position III and the extreme position IV.

[0106] Similarly, the above-mentioned extrusion force is formed by the deformation of the second force-applying member 330 when it is engaged in the second groove 312. The strength of the extrusion force is moderate, and it can cause the second passive member 320 to rotate together with the second active member 310 when the second limit block 322 does not touch the side wall of the second limit groove 131. Once the second limit block 322 touches the side wall of the second limit groove 131, when the second active member 310 is turned with force, the second passive member 320 is restricted by the side wall of the second limit groove 131 and will not be able to continue to rotate together with the second active member 310. The second active member 310 can only rotate by itself (at this time, the second force-applying member 330 rotates together with the second active member 310 and slides relative to the second passive member 320), thereby changing the distance between the third end face 3111 and the second dividing block 321, and then changing the metering volume of the second metering space 3a.

[0107] Preferably, the first force applying member 230 and the second force applying member 330 are both non-closed annular structures, and the central angle corresponding to the non-closed annular structure is greater than 180°. For example, as shown in the figure, the central angle corresponding to the annular structure of the first force applying member 230 or the second force applying member 330 is between 210° and 300°.

[0108] The first force-applying member 230 or the second force-applying member 330 of the above-mentioned structure will form an annular tightening effect on the first passive member 220 or the second passive member 320. The annular tightening effect is similar to the braking principle, and can wrap and clamp the first passive member 220 or the second passive member 320, so that when the first force-applying member 230 or the second force-applying member 330 drives the first passive member 220 or the second passive member 320 to rotate, the first passive member 220 or the second passive member 320 can rotate more stably to avoid relative sliding.

[0109] In order to facilitate the driving of the first active member 210 and the second active member 310 to rotate, a first matching structure that can cooperate with an external driving component to drive the first active member 210 to rotate is provided on the outer wall of the first active member 210, and a second matching structure that can cooperate with an external driving component to drive the second active member 310 to rotate is provided on the outer wall of the second active member 310.

[0110] In a preferred embodiment, see Figures 1 to 13 The first matching structure is two first protrusions 213 arranged at intervals, and the second matching structure is two second protrusions 313 arranged at intervals.

[0111] See also Fig.15The external driving component matched with the first protrusion 213 includes a first arc-shaped rack 510, two first passive gears 520 and a first driving gear 530. The first arc-shaped rack 510 has two first slots on its inner side and a first arc-shaped tooth surface 511 on its outer side. The first arc-shaped tooth surface 511 meshes with the two first passive gears 520 at the same time. The two first passive gears 520 also mesh with the first driving gear 530 at the same time. The first driving gear 530 is installed on the output shaft of one of the motors (not shown in the figure).

[0112] Similarly, see Fig.15 The external driving component matched with the second protrusion 313 includes a second arc-shaped rack 540, two second passive gears 550 and a second driving gear 560. The second arc-shaped rack 540 has two second slots on its inner side and a second arc-shaped tooth surface 541 on its outer side. The second arc-shaped tooth surface 541 meshes with the two second passive gears 550 at the same time. The two second passive gears 550 also mesh with the second driving gear 560 at the same time. The second driving gear 560 is installed on the output shaft of another motor (not shown in the figure).

[0113] When working, see Fig.15 The two first protrusions 213 are respectively inserted into the two first slots on the inner side of the first arc-shaped rack 510, and the two second protrusions 313 are respectively inserted into the two second slots on the inner side of the second arc-shaped rack 540; thereafter, starting one of the motors or starting both motors at the same time can drive one of the active parts to rotate or drive both active parts to rotate at the same time, thereby achieving the purpose of allowing medicine to fall from only one of the discharge ports or both discharge ports at the same time.

[0114] The above-mentioned arrangement of the first matching structure and the second matching structure as two spaced protrusions (i.e., the first protrusion 213 and the second protrusion 313) has the following advantages: the contact area is larger, and when the arc-shaped rack (i.e., the first arc-shaped rack 510 or the second arc-shaped rack 540) drives the first active member 210 or the second active member 310 to rotate through the cooperation of the two slots and the two protrusions, the force surface is larger and the rotation is more stable.

[0115] In another preferred embodiment, see Fig.16 The first matching structure is the first tooth surface 214 , and the second matching structure is the second tooth surface 314 .

[0116] Therefore, in the process of automatic dispensing, the motor can be used to drive the gear to rotate, and then the meshing relationship between the gear and the first tooth surface 214 or the second tooth surface 314 can be used to drive the first active member 210 or the second active member 310 to rotate (not shown in the figure). The first active member 210 and the second active member 310 are respectively driven to rotate by two motors, so when dropping medicine, it can be selected to let the two motors work at the same time or only let one motor work, so as to achieve the purpose of dropping medicine at two discharge ports at the same time, or only let one discharge port drop medicine.

[0117] In the above two forms of the first matching structure and the second matching structure, when the first passive member 220 rotates to the extreme position I, in the subsequent process of driving the first active member 210 to rotate, the rotation angle of the motor can be controlled to control the metering volume of the first metering space 2a, thereby achieving the purpose of adjusting the metering volume of the first metering space 2a. Similarly, when the second passive member 320 rotates to the extreme position III, in the subsequent process of driving the second active member 310 to rotate, the rotation angle of the motor can be controlled to control the metering volume of the second metering space 3a, thereby achieving the purpose of adjusting the metering volume of the second metering space 3a.

[0118] When the medicine bottle cap of the utility model is used, medicine can be dropped from two discharge ports at the same time, or medicine can be dropped from only one discharge port while medicine is not dropped from the other discharge port.

[0119] The following is a detailed description of the working principle by assuming that only the first discharge port 1c allows the medicine to fall, while the second discharge port 1d does not allow the medicine to fall:

[0120] Before use, the medicine bottle cap of the utility model is connected to the bottle mouth of the medicine bottle 400 by threaded connection;

[0121] When in use, turn the medicine bottle 400 and the medicine bottle cap upside down. The effect after inversion is as follows: Fig.14 As shown, the medicine bottle 400 is pre-filled with Chinese medicine particles;

[0122] Before letting the medicine fall into the first discharge port 1c, the first metering space 2a needs to be fed first. Specifically, before feeding, the first passive member 220 stays at the extreme position I, and at the same time, the first end face 2111 is fitted together with the first dividing block 221. At this time, the metering volume of the first metering space 2a is zero; during feeding, the motor drives the first active member 210 to rotate in the positive direction through the gear, so that the first end face 2111 rotates toward the side away from the first dividing block 221, and during the rotation, the first passive member 220 is restricted by the first limiting groove 111 and will remain motionless. When the first end face 2111 rotates to a predetermined position, the motor stops working. At this time, the first metering space 2a between the first end face 2111 and the first dividing block 221 is adjusted to a preset volume, see Fig.10 , the arrow in the figure indicates the rotation direction of the first active member 210 when it rotates in the forward direction; during this process, the Chinese medicine particles in the medicine bottle 400 will enter the first metering space 2a from the first feed port 1a and fill the first metering space 2a;

[0123] Afterwards, the motor drives the first active member 210 to rotate in the opposite direction through the gears. During the rotation, since the first limit block 222 will not be restricted by the first limit groove 111, under the action of the first force-applying member 230, the first passive member 220 will rotate together with the first active member 210, so the first metering space 2a will maintain a constant volume and eventually rotate to the limit position II. At this time, the first metering space 2a is connected to the first discharge port 1c, and the Chinese medicine particles in the first metering space 2a begin to fall from the first discharge port 1c. Fig.11 , the arrow in the figure indicates the direction of rotation of the first active member 210 when it rotates in the reverse direction; in order to ensure that there is no residual Chinese medicine particles in the first metering space 2a and they can fall completely, at this time, the motor will continue to drive the first active member 210 to rotate in the reverse direction. During the rotation, the first passive member 220 will remain motionless due to the restriction of the first limiting groove 111. Therefore, the first end surface 2111 will gradually approach the first partition block 221 until it is fitted together with the first partition block 221. As a result, the metering volume of the first metering space 2a is reduced to zero, and the Chinese medicine particles in the first metering space 2a are completely emptied and all fall from the first discharge port 1c; and a packaging bag is pre-placed below the first discharge port 1c, so the fallen Chinese medicine particles will all fall into the packaging bag;

[0124] During the above process, the motor controlling the second active member 310 remains stationary.

[0125] Thus, the process of allowing medicine to fall only from the first discharge port 1c and not from the second discharge port 1d is completed.

[0126] When it is necessary to allow only the second discharge port 1d to drop medicine, and not allow the first discharge port 1c to drop medicine, the working principle is similar to the above, and another motor is operated to first drive the second active member 310 to rotate forward, so that the second metering space 3a is adjusted to a preset volume (see Fig.12 , the arrow in the figure is the rotation direction of the second active component 310 when it rotates forward), after the Chinese medicine particles in the medicine bottle 400 enter and fill the second metering space 3a, the motor drives the second active component 310 to rotate in the opposite direction. During the rotation, the second metering space 3a is first connected to the second discharge port 1d, and then the second active component 310 continues to rotate until the third end face 3111 fits together with the second partition block 321. At this time, the metering volume of the second metering space 3a is reduced to zero, and all the Chinese medicine particles that have entered the second metering space 3a will fall from the second discharge port 1d and fall into the packaging bag below; thus, the process of only allowing the second discharge port 1d to drop medicine, while the first discharge port 1c does not drop medicine is completed. It should be noted that during the entire process, the motor controlling the first active component 210 always remains stationary;

[0127] When it is necessary to allow the first discharge port 1c and the second discharge port 1d to drop medicine at the same time, two motors can be activated at the same time to control the first active member 210 and the second active member 310 to rotate forward at the same time first, and then rotate backward at the same time, and finally the process of allowing the first discharge port 1c and the second discharge port 1d to drop medicine at the same time can be completed. The specific action steps are similar to the above and will not be repeated here.

[0128] It can be seen that when preparing Chinese medicine, the bottle cap of the utility model can allow the two discharge ports to drop medicine at the same time, or can choose to allow only one of the discharge ports to drop medicine, while the other discharge port does not drop medicine. When the number of bags of Chinese medicine to be prepared is an odd number, the bottle cap of the utility model can accurately prepare the corresponding number of bags. For example, in the prescription issued by the doctor, the way of taking medicine is: take one bag at a time, take it three times a day, and take it for a total of three days, that is, a total of nine bags of Chinese medicine need to be prepared. When the bottle cap of the utility model is used for preparation, the two discharge ports can be allowed to drop medicine at the same time, and the medicine is prepared in the manner of two bags at a time. After the fourth round of preparation, a total of eight bags are prepared, and there is still one bag missing. In the last round, only one of the discharge ports can be allowed to drop medicine, and the other discharge port can not drop medicine, so as to complete the preparation of only one bag of Chinese medicine. Finally, nine bags of Chinese medicine are prepared. Therefore, unlike the previous bottle cap, one more bag will be prepared in the last round, resulting in unnecessary waste.

[0129] 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.
