Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medicine production technology especially, it relates to a kind of quantitative unloading bottle cap used in traditional Chinese medicine dispensing process with medicament bottle. BACKGROUND

[0002] At present, in the dispensing process of traditional Chinese medicine granules, relatively automatic dispensing mode has been realized, and this kind of automatic dispensing mode usually involves a special bottle cap, which has a metering function, and is provided on the bottle mouth of the medicament bottle. With the cooperation of the corresponding automatic equipment and program, automatic quantitative dispensing can be realized.

[0003] However, the amount of single dispensing of the above-mentioned bottle cap is usually fixed and unchangeable, so there are certain defects in actual use, i.e. only the designed fixed capacity can be dispensed each time, and the amount of single dispensing cannot be changed. Therefore, if the dispensing ratio changes, the bottle cap may no longer be suitable and needs to be redesigned and replaced. INVENTION CONTENTS

[0004] The technical problem to be solved by the utility model is to provide a metering cavity control assembly for a quantitative unloading bottle cap and a quantitative unloading bottle cap, so that the unloading bottle cap can meet the automatic dispensing while allowing the amount of single dispensing to be adjusted within a certain range, thereby improving the applicability of the unloading bottle cap.

[0005] The technical solution adopted by the utility model to solve its technical problem is as follows:

[0006] The first rotating member is provided with a sector-shaped missing slot and a sector-shaped body formed at the same time when the sector-shaped missing slot is formed on the peripheral surface thereof. One of the sidewalls of the sector-shaped body in the arc direction is a first wall surface, and a cavity is formed below the sector-shaped body, and a slot is formed on the outer side of the sector-shaped body in the radial direction.

[0007] The second rotating member includes an annular body, a partition block and an elastic body. The annular body is sleeved on the periphery of the sector-shaped body, and the annular body is provided with a first rotation limiting structure for limiting the rotation angle of the second rotating member. The partition block is connected to the inner wall of the annular body and is inserted into the sector-shaped missing slot and abuts with the inner wall in the radial direction of the sector-shaped missing slot, wherein the area between the first wall surface and the partition block is a metering cavity. The elastic body is connected to the inner wall of the annular body and is inserted into the cavity from the slot and is pressed against the inner wall in the radial direction of the cavity.

[0008] In the above-mentioned metering cavity control assembly, the metering cavity is used to store the medicament particles that need to be dispensed.

[0009] Since the second rotating member is pressed against the inner wall of the cavity below the fan-shaped body in the radial direction by the elastic body, the second rotating member can be clamped on the first rotating member, and the first rotating member can drive the second rotating member to rotate synchronously. However, if the second rotating member can only rotate synchronously with the first rotating member, the volume of the metering cavity will not change, and only a fixed amount of medicine can be dispensed. Therefore, the first rotation limiting structure is arranged on the second rotating member, which can limit the rotation angle of the second rotating member. Therefore, during operation, the first rotation limiting structure can be limited at an appropriate position, so that the second rotating member remains stationary, and only the first rotating member rotates and slides relative to the second rotating member, thereby changing the distance between the first wall surface and the partition block, changing the volume of the metering cavity, and adjusting the amount of medicine dispensed at a time.

[0010] Preferably, the elastic body comprises an arc-shaped pressing plate and an elastic member.

[0011] The elastic member is connected to the inner wall of the annular body.

[0012] The arc-shaped pressing plate is connected to one side of the elastic member away from the inner wall of the annular body, and the arc-shaped pressing plate is attached to the inner wall of the cavity in the radial direction. At the same time, the arc-shaped pressing plate exerts pressure on the elastic member to form a counteracting force, forcing the arc-shaped pressing plate to tightly contact the inner wall of the cavity in the radial direction.

[0013] Preferably, the elastic member comprises two arc-shaped bending plates, which are oppositely arranged on the back side of the arc-shaped pressing plate and connected and fixed to the inner wall of the annular body. The two arc-shaped bending plates form the counteracting force through their own bending deformation.

[0014] Preferably, the second rotating member further comprises a top block, which is arranged between the two arc-shaped bending plates and fixed to the annular body, for limiting the maximum displacement of the arc-shaped pressing plate when pressing the two arc-shaped bending plates.

[0015] Preferably, the second rotating member and the first rotating member maintain the close contact between the inner wall of the annular body and the outer wall of the fan-shaped body in the radial direction through the clamping structure.

[0016] Preferably, the clamping structure comprises an arc-shaped clamping ring and an arc-shaped clamping groove. The arc-shaped clamping ring is arranged on the outer side of the fan-shaped body in the radial direction and above the slot.

The arc-shaped clamping ring is adapted to the arc-shaped clamping groove and clamped into the arc-shaped clamping groove.

[0017] Preferably, the outer wall of the top block in the radial direction is pressed against the inner wall of the arc-shaped clasp ring in the radial direction under the action of the force generated by the deformation of the two arc-shaped bent plates.

[0018] In a second aspect, the utility model also provides a quantitative discharging bottle cap, it includes: rotator, discharging bottom cover, feed top cover and above-mentioned measurement cavity control component,

[0019] The rotator is provided with a discharging avoiding hole.

[0020] The discharging bottom cover is arranged above the rotator, the discharging bottom cover has a first cavity, the bottom of the first cavity is provided with a discharging hole, and a second rotation limiting structure is arranged at a predetermined position of the first cavity.

[0022] The feed top cover is arranged above the measurement cavity control component and is fixedly connected with the discharging bottom cover, the top of the feed top cover is used for being connected with the bottle mouth of a medicament bottle, and the bottom of the feed top cover is provided with a feeding hole.

[0023] When the measurement cavity corresponds to the feeding hole, the rotator can drive the first rotating member to slide relative to the second rotating member, so that the volume of the measurement cavity gradually increases, and when the measurement cavity corresponds to the discharging hole, the rotator can drive the first rotating member to slide relative to the second rotating member, so that the volume of the measurement cavity gradually decreases.

[0024] Preferably, the point positions passed by the rotator in the rotation angle range include a feeding starting point position and a discharging starting point position.

[0025] When the rotating body rotates to the feeding starting point along the first clockwise direction, the metering cavity corresponds to the feeding hole at this time, if the rotating body continues to rotate along the first clockwise direction subsequently, the second rotating part is kept stationary by the cooperation relationship between the first rotation limiting structure and the second rotation limiting structure, and the first rotating part continues to rotate, so that the first wall surface gradually moves away from the partition block, and the volume of the metering cavity gradually increases; after that, when the rotating body rotates to the discharging starting point along the second clockwise direction, the second rotating part is in the range of allowing rotation, and rotates synchronously with the first rotating part.

[0026] When the rotating body rotates to the discharging starting point along the second clockwise direction, the metering cavity corresponds to the corresponding discharging hole at this time, if the rotating body continues to rotate along the second clockwise direction subsequently, the second rotating part is kept stationary by the cooperation relationship between the first rotation limiting structure and the second rotation limiting structure, and the first rotating part continues to rotate, so that the first wall surface gradually moves close to the partition block, and the volume of the metering cavity gradually decreases; after that, when the rotating body rotates to the feeding starting point along the first clockwise direction, the second rotating part is in the range of allowing rotation, and rotates synchronously with the first rotating part.

[0045] The present utility model will be further described in detail in combination with specific embodiments, but the implementation mode of the present utility model is not limited thereto.

[0046] Embodiment 1:

[0047] As Figures 1 to 6 ​​​​​As shown, the embodiment provides a metering cavity control assembly for quantitatively dispensing bottle caps, which comprises a first rotating member 310 and a second rotating member 320.

[0048] The peripheral surface of the first rotating member 310 is provided with a sector-shaped missing slot 312 and a sector body 311 formed simultaneously when the sector-shaped missing slot 312 is formed. One of the sidewalls of the sector body 311 in the arc direction is a first wall surface 3111, the lower portion of the sector body 311 is provided with a cavity 313, and the outer side of the sector body 311 in the radial direction is formed with a slot 314.

[0049] The second rotating member 320 comprises a ring body 321, a partition block 322 and an elastic body 323. The ring body 321 is sleeved on the periphery of the sector body 311, and the ring body 321 is provided with a first rotation limiting structure 3211 for limiting the rotation angle of the second rotating member 320. The partition block 322 is connected to the inner wall of the ring body 321 and is inserted into the sector-shaped missing slot 312 and abuts against the inner wall of the sector-shaped missing slot 312 in the radial direction, wherein the area between the first wall surface 3111 and the partition block 322 is a metering cavity 3a (see Figure 1 ). The elastic body 323 is connected to the inner wall of the ring body 321 and is inserted into the cavity 313 by the slot 314 and abuts against the inner wall of the cavity 313 in the radial direction.

[0050] The first rotating member 310 can be driven to rotate by corresponding components, and in the rotation process, the first rotation limiting structure 3211 cooperates with the second rotation structure on the corresponding components to limit whether the second rotating member 320 rotates with the first rotating member 310.

[0051] In the metering cavity control assembly of the embodiment, the metering cavity 3a is used to store the medicament particles that need to be dispensed.

[0052] Since the second rotating member 320 abuts against the inner wall of the cavity 313 in the radial direction of the sector body 311 by the elastic body 323, the second rotating member 320 can be clamped on the first rotating member 310, and the first rotating member 310 can drive the second rotating member 320 to rotate synchronously. At the same time, the first rotation limiting structure 3211 is arranged on the second rotating member 320, which can limit the rotation angle of the second rotating member 320. Therefore, in the working process, the first rotation limiting structure 3211 can be limited at a suitable position, so that the second rotating member 320 remains stationary and only the first rotating member 310 rotates, and the relative sliding between the first rotating member 310 and the second rotating member 320 occurs when rotating, so that the distance between the first wall surface 3111 and the partition block 322 can be changed, and the volume of the metering cavity 3a can be changed, so that the amount of single dispensing can be adjusted.

[0053] In a preferred embodiment, referring to Figure 3 and Figure 4 The elastic body 323 comprises an arc-shaped pressing plate 3231 and an elastic member.

[0054] The elastic member is connected to the inner wall of the annular body 321.

[0055] The arc-shaped pressing plate 3231 is connected to the side of the elastic member away from the inner wall of the annular body 321. The arc-shaped pressing plate 3231 is in contact with the inner wall of the cavity 313 in the radial direction, and the arc-shaped pressing plate 3231 exerts a pressing force on the elastic member, so that the elastic member generates a counteracting force to force the arc-shaped pressing plate 3231 to tightly contact the inner wall of the cavity 313 in the radial direction.

[0056] Further, referring to Figure 3 and Figure 4 The elastic member comprises two arc-shaped bending plates 3232. The two arc-shaped bending plates 3232 are oppositely arranged on the back side of the arc-shaped pressing plate 3231 and are fixedly connected to the inner wall of the annular body 321. The two arc-shaped bending plates 3232 generate the counteracting force by their own bending deformation. Preferably, Figure 3 and Figure 4 The bending directions of the two arc-shaped bending plates 3232 are respectively bent to both sides.

[0057] When assembling the first rotating member 310 and the second rotating member 320, the annular body 321 is sleeved on the outer periphery of the sector body 311, and the elastic body 323 is placed into the cavity 313 through the slot 314. During the placing process, the arc-shaped pressing plate 3231 is slightly bent outward and pressed downward, so that the arc-shaped pressing plate 3231 is clamped into the cavity 313 by extruding the arc-shaped bending plates 3232. After clamping, the arc-shaped pressing plate 3231 is tightly pressed against the inner wall of the cavity 313 in the radial direction under the action of the arc-shaped bending plates 3232. Thus, the assembly of the two is completed.

[0058] In a preferred embodiment, referring to Figure 3 and Figure 4 The second rotating member 320 further comprises a top block 324. The top block 324 is arranged between the two arc-shaped bending plates 3232 and is fixedly connected to the annular body 321, and is used to limit the maximum displacement of the arc-shaped pressing plate 3231 when extruding the two arc-shaped bending plates 3232.

[0059] In order to avoid the displacement of the arc-shaped pressing plate 3231 being too large, causing the arc-shaped bending plate 3232 to be excessively pressed and broken, the top block 324 is specially added in the above embodiment, which can abut against the arc-shaped pressing plate 3231 at a certain distance on the rear side, limiting the maximum displacement of the arc-shaped pressing plate 3231, and avoiding the excessive deformation of the arc-shaped bending plate 3232 and the breaking of the arc-shaped bending plate 3232.

[0060] In a preferred embodiment, the second rotating member 320 and the first rotating member 310 maintain the close fit between the inner wall of the annular body 321 and the outer wall of the fan-shaped body 311 in the radial direction through a clamping structure.

[0061] Specifically, referring to Figure 3 and Figure 4 , the clamping structure includes an arc-shaped clamping ring 315 and an arc-shaped clamping groove 325. The arc-shaped clamping ring 315 is arranged on the outer side of the fan-shaped body 311 in the radial direction and above the slot 314. The arc-shaped clamping groove 325 is arranged between the upper region of the top block 324 and the annular body 321. The arc-shaped clamping ring 315 is adapted to the arc-shaped clamping groove 325 and clamped into the arc-shaped clamping groove 325.

[0062] Further, the outer wall of the top block 324 in the radial direction is pressed against the inner wall of the arc-shaped clamping ring 315 under the action of the deformation force generated by the two arc-shaped bending plates 3232.

[0063] In the above embodiment, the arc-shaped clamping ring 315 and the arc-shaped clamping groove 325 function as follows: when the arc-shaped bending plate 3232 exerts a force on the arc-shaped pressing plate 3231, it will also exert a counteracting force on the annular body 321. Therefore, the annular body 321 may be deformed, i.e., the diameter corresponding to the arc-shaped bending plate 3232 may be affected by the counteracting force of the arc-shaped bending plate 3232 and become larger, causing a gap to appear between the inner wall of the annular body 321 and the outer wall of the fan-shaped body 311 in the radial direction. To this end, the arc-shaped clamping ring 315 and the arc-shaped clamping groove 325 are specially added, which are clamped into the arc-shaped clamping groove 325 and abut against the outer wall of the top block 324, so as to limit the shape of the annular body 321 and avoid its deformation, thereby eliminating the above-mentioned gap.

[0064] In addition, due to the action force generated by the deformation of the two arc-shaped bent plates 3232, the outer wall of the top block 324 in the radial direction is also pressed against the inner wall of the arc-shaped clamping ring 315 in the radial direction. Therefore, the arrangement of the arc-shaped clamping ring 315 and the arc-shaped clamping groove 325 can also increase the friction between the first rotating part 310 and the second rotating part 320, so that the two arc-shaped bent plates 3232 not only press against the inner wall of the cavity 313, but also press against the outer wall of the cavity 313 (i.e., the inner wall of the arc-shaped clamping ring 315), so that the inner and outer walls of the cavity 313 are pressed against by the arc-shaped pressing plate 3231 and the top block 324 respectively. Compared with the case where only the inner wall of the cavity 313 is pressed against, the friction can be further increased, and the reliability of the synchronous rotation of the first rotating part 310 and the second rotating part 320 can be ensured.

[0065] The cooperation of the arc-shaped clamping ring 315 and the arc-shaped clamping groove 325 can also increase the friction between the first rotating part 310 and the second rotating part 320, so that the two can be more reliably synchronized.

[0066] Preferably, as shown in Figures 1 to 4 In order to improve the work efficiency of dispensing, the number of the metering cavities 3a is usually designed to be two and arranged oppositely.

[0067] Correspondingly, in the first rotating part 310, the number of the structures such as the sector 311, the sector-shaped slot 312, the cavity 313, the slot 314, the arc-shaped clamping ring 315, and the first wall surface 3111 is also two, and they are also arranged oppositely.

[0068] Correspondingly, in the second rotating part 320, the number of the structures such as the partition block 322, the elastic body 323, the top block 324, the arc-shaped clamping groove 325, and the first rotation limiting structure 3211 is also two, and they are also arranged oppositely. The two elastic bodies 323 can press the inner walls of the two cavities 313 from both sides to increase the friction for clamping the first rotating part 310.

[0069] Therefore, when dispensing, the two metering cavities 3a can simultaneously receive the medicine, and then simultaneously dispense the medicine. Compared with the structure with only one metering cavity 3a, the work efficiency of dispensing can be improved.

[0070] Embodiment 2:

[0071] Referring to Figures 7 to 11 This embodiment based on embodiment 1 provides a quantitative dispensing bottle cap, which comprises a rotating body 100, a dispensing bottom cover 200, a feeding top cover 400, and the metering cavity control assembly 300 of embodiment 1.

[0072] The rotating body 100 is provided with a dispensing avoiding hole 110.

[0073] The lower discharging bottom cover 200 is arranged above the rotating body 100, and the lower discharging bottom cover 200 has a first cavity 210, the bottom of the first cavity 210 is provided with a discharging hole 220, and a second rotation limiting structure 230 is arranged at a predetermined position of the first cavity 210. Moreover, the rotating body 100 can independently rotate relative to the lower discharging bottom cover 200.

[0074] The metering cavity control assembly 300 is arranged in the first cavity 210. The first rotating part 310 synchronously rotates with the rotating body 100, the rotation range of the second rotating part 320 is restricted by the cooperation relationship between the first rotation limiting structure 3211 and the second rotation limiting structure 230, and the second rotating part 320 synchronously rotates with the first rotating part 310 in the range of the allowed rotation and can slide relative to the first rotating part 310 in the range of the disallowed rotation under the extrusion of the elastic body 323.

[0075] The feeding top cover 400 is arranged above the metering cavity control assembly 300 and is fixedly connected with the lower discharging bottom cover 200, the top of the feeding top cover 400 is used for being connected with the bottle mouth of a medicine bottle, and the bottom is provided with a feeding hole 410.

[0076] When the metering cavity 3a corresponds to the feeding hole 410, the rotating body 100 can drive the first rotating part 310 to slide relative to the second rotating part 320, so that the volume of the metering cavity 3a gradually increases. When the metering cavity 3a corresponds to the discharging hole 220, the rotating body 100 can drive the first rotating part 310 to slide relative to the second rotating part 320, so that the volume of the metering cavity 3a gradually decreases.

[0077] In the above-mentioned quantitative discharging bottle cap, the discharging avoiding hole 110 is used for avoiding the discharging hole 220 when the medicine is discharged, and the bottom of the discharging hole 220 is opened, so that the medicine can be smoothly discharged.

[0078] In the above-mentioned quantitative discharging bottle cap, the metering cavity 3a is used for temporarily storing the medicine, and the volume of the metering cavity 3a determines the amount of the medicine released at a time, that is, when the metering cavity 3a communicates with the feeding hole 410, the larger the volume of the metering cavity 3a is, the more the medicine entering the metering cavity 3a from the feeding hole 410 is, so that more medicine can be released when the metering cavity 3a communicates with the discharging hole 220 subsequently. Conversely, the smaller the volume of the metering cavity 3a is, the less the medicine released when the medicine is discharged is.

[0079] In a preferred embodiment, the rotating body 100 passes through a point position in a rotation angle range, and the point position includes a feeding starting point position and a discharging starting point position.

[0080] When the rotating body 100 rotates to the feeding starting point in the first clockwise direction, as shown in Figure 12 , at this time, the metering cavity 3a is in communication with the feeding hole 410, and if the rotating body 100 continues to rotate in the first clockwise direction, the second rotating part 320 will be kept stationary due to the cooperation between the first rotation limiting structure 3211 and the second rotation limiting structure 230, while the first rotating part 310 will continue to rotate, so that the first wall surface 3111 gradually moves away from the partition block 322, thereby gradually increasing the volume of the metering cavity 3a, as shown in Figure 13 . After that, when the rotating body 100 rotates to the discharging starting point in the second clockwise direction, the second rotating part 320 will rotate synchronously with the first rotating part 310 since it is within the range of allowed rotation.

[0081] When the rotating body 100 rotates to the discharging starting point in the second clockwise direction, as shown in Figure 14 , at this time, the metering cavity 3a is in communication with the corresponding discharging hole 220, and if the rotating body 100 continues to rotate in the second clockwise direction, the second rotating part 320 will be kept stationary due to the cooperation between the first rotation limiting structure 3211 and the second rotation limiting structure 230, while the first rotating part 310 will continue to rotate, so that the first wall surface 3111 gradually moves towards the partition block 322, thereby gradually reducing the volume of the metering cavity 3a, as shown in Figure 15 . After that, when the rotating body 100 rotates to the feeding starting point in the first clockwise direction, the second rotating part 320 will rotate synchronously with the first rotating part 310 since it is within the range of allowed rotation.

[0082] As can be seen from the above, since the volume of the metering cavity 3a can be adjusted when it is in communication with the feeding hole 410, i.e., the volume of the metering cavity 3a will gradually increase when the rotating body 100 rotates in the first clockwise direction, therefore, the amount of medicine discharged at one time in the above-mentioned dosing discharging bottle cap can be adjusted within a certain range. Thus, compared with the existing bottle cap, the dosing discharging bottle cap of the present embodiment has better applicability, and when the proportion of the medicine to be dispensed changes, the volume of the metering cavity 3a can be adjusted accordingly to adapt the amount of medicine discharged at one time, thereby meeting the corresponding dispensing proportion.

[0083] In a preferred embodiment, as shown in Figure 3 , Figure 4 or Figure 8 , Figure 10 , the first rotation limiting structure 3211 is an arc-shaped groove arranged on the lower side of the outer wall of the annular body 321, and the second rotation limiting structure 230 is a protrusion arranged on the inner wall bottom of the first cavity 210 and corresponding to the arc-shaped groove.

[0084] The protruding block is clamped in the arc-shaped groove, and the protruding block is narrow and the arc-shaped groove is long, so the arc covered by the protruding block is much smaller than the arc covered by the arc-shaped groove. Therefore, the protruding block limits the rotation range of the second rotating member 320. When the second rotating member 320 rotates to a side wall of the arc-shaped groove and abuts against the protruding block, the second rotating member 320 cannot continue to rotate in the previous direction, so as to limit the rotation angle of the second rotating member 320.

[0085] In the technical solution, the first rotating member 310 is always linked with the rotating body 100, so when the rotating body 100 rotates, the first rotating member 310 always rotates synchronously with the rotating body 100. The second rotating member 320 is clamped on the periphery of the first rotating member 310 by the elastic body 323, so when the first rotating member 310 rotates, the second rotating member 320 can rotate with the first rotating member 310 under the friction of the elastic body 323. Thus, the metering cavity 3a can be rotated to a position in communication with the feeding hole 410 or the discharging hole 220.

[0086] In addition, in order to adjust the volume of the metering cavity 3a, the first rotation limiting structure 3211 and the second rotation limiting structure 230 are specially added. When the second rotating member 320 rotates to a specific position, it cannot continue to rotate with the first rotating member 310, so as to change the distance between the first wall surface 3111 and the partition block 322 during subsequent rotation of the first rotating member 310, thereby achieving the purpose of changing the volume of the metering cavity 3a.

[0087] Specifically:

[0088] As shown in Figure 12 the feeding hole 410, the hole wall close to the discharging hole 220 is the front wall 411 of the feeding hole, and the hole wall away from the discharging hole 220 is the rear wall 412 of the feeding hole; Figure 12 is an exploded view of the rotating body 100 rotating in the first clockwise direction (i.e. counterclockwise direction in the figure) to the feeding starting point. At this time, the first rotation limiting structure 3211 rotates to one of the limit positions relative to the second rotation limiting structure 230, the first wall surface 3111 is aligned with the front wall 411 of the feeding hole 410 above and below, and the volume of the metering cavity 3a is zero; in Figure 12On the basis, if the rotating body 100 continues to rotate in the first clockwise direction (i.e. counterclockwise direction in the figure), it is blocked by the second rotation limiting structure 230, the second rotating part 320 cannot follow the rotation and can only remain stationary, and the first rotating part 310 will rotate with the rotating body 100, so the first wall surface 3111 will gradually move away from the partition block 322, thereby gradually increasing the volume of the metering cavity 3a, as shown in Figure 13 , which is a display diagram of the volume of the metering cavity 3a after the first rotating part 310 rotates;

[0089] As shown in Figure 14 , the hole wall near the inlet hole 410 of the discharge hole 220 is the rear wall 222 of the discharge hole, and the hole wall away from the inlet hole 410 is the front wall 221 of the discharge hole; Figure 14 is an exploded view of the rotating body 100 rotating to the starting point of the discharging in the second clockwise direction (i.e. clockwise direction in the figure), at this time, the first rotation limiting structure 3211 rotates to the limit position on the other side relative to the second rotation limiting structure 230, and the side wall of the partition block 322 near the first wall surface 3111 is aligned with the front wall 221 of the discharge hole up and down; on the basis Figure 14 , if the rotating body 100 continues to rotate in the second clockwise direction (i.e. clockwise direction in the figure), it is blocked by the second rotation limiting structure 230, the second rotating part 320 cannot follow the rotation and can only remain stationary, and the first rotating part 310 will rotate with the rotating body 100, so the first wall surface 3111 will gradually move away from the partition block 322, thereby gradually increasing the volume of the metering cavity 3a, as shown in Figure 15 .

[0090] Based on the above technical scheme, the first rotating part 310 can drive the second rotating part 320 to rotate together through the clamping action of the elastic body 323, but the rotation range of the second rotating part 320 is limited by the cooperation relationship between the first rotation limiting structure 3211 and the second rotation limiting structure 230, that is, only when the first rotation limiting structure 3211 is not blocked by the second rotation limiting structure 230, the rotation of the first rotating part 310 will drive the second rotating part 320 to rotate together, otherwise, when the first rotation limiting structure 3211 is blocked by the second rotation limiting structure 230, the first rotating part 310 rotates, and the second rotating part 320 will remain stationary, and the two will slide relative to each other. When the second rotating part 320 rotates together with the first rotating part 310, the effect is to allow the metering cavity 3a to be rotated to a position in communication with the feed hole 410 or a position in communication with the discharge hole 220. When the second rotating part 320 cannot rotate together with the first rotating part 310, the effect is to allow the volume of the metering cavity 3a to gradually increase or decrease, and during the increasing process, the feed volume of the metering cavity 3a is changed, and during the decreasing process, the medicament in the metering cavity 3a is gradually discharged from the discharge hole 220.

[0091] Preferably, in the present embodiment, the number of metering cavities 3a is designed to be two, and they are oppositely arranged. Correspondingly, in the first rotating part 310, the number of structures such as the sector body 311, the sector-shaped slot 312, the cavity 313, the slot 314, the arc-shaped clasp ring 315, and the first wall surface 3111 is also two, and they are also oppositely arranged; in the second rotating part 320, the number of structures such as the partition block 322, the elastic body 323, the top block 324, the arc-shaped clasp slot 325, and the first rotation limiting structure 3211 is also two, and they are also oppositely arranged; in the feed top cover 400, the number of feed holes 410 is also two, and they are also oppositely arranged; in the discharge bottom cover 200, the number of discharge holes 220 and the second rotation limiting structure 230 is also two, and they are also oppositely arranged; in the rotating body 100, the number of avoiding holes 110 is also two, and they are also oppositely arranged.

[0092] In a preferred embodiment, the first rotating part 310 is linked with the rotating body 100 through the following structure, specifically:

[0093] As shown in Figure 8 The middle part of the rotating body 100 is provided with a polygonal boss 120, and the middle part of the first rotating part 310 is provided with a polygonal notch 316 matched with the polygonal boss 120, and the polygonal boss 120 is clamped into the polygonal notch 316 to realize the synchronous rotation of the first rotating part 310 with the rotating body 100.

[0094] In a preferred embodiment, as shown in Figure 7 andFigure 8 As shown in the drawings, the quantitative dosing bottle cap further comprises a flow guide 500, the bottom of which is provided with a flow guide slope 510 for facilitating the introduction of the medicament into the feeding hole 410, and the flow guide 500 is fixedly connected with the rotating body 100 and can move together with the rotating body 100.

[0095] Preferably, the bottom of the flow guide 500 is provided with a connecting head 530 matching the outer contour of the polygonal boss 120, which is inserted into the polygonal notch 316 of the first rotating member 310 and fixedly connected with the polygonal boss 120 through a screw. In addition, the side surface of the flow guide 500 is provided with two stirring rods 520 for disturbing the medicament.

[0096] Therefore, when the rotating body 100 is rotated, the flow guide 500 will rotate together, so that the stirring rods 520 fixed on the flow guide 500 can disturb the medicament, avoiding the medicament being stuck above the feeding hole 410 and failing to fall down.

[0097] In a preferred embodiment, as shown in Figure 7 and Figure 8 the top of the flow guide 500 is provided with an RFID tag 700, on which the information of the name of the drug is recorded. By identifying the RFID tag 700, the type of the medicament can be known, so as to realize automatic dispensing.

[0098] In a preferred embodiment, as shown in Figure 7 and Figure 8 the outer wall of the rotating body 100 is provided with two driving lugs 130 in opposition, and the outer wall of the feeding top cover 400 is provided with two positioning lugs 420 in opposition.

[0099] Referring to Figure 8 and Figure 10 the top of the driving lug 130 is provided with a first magnet 140, and the bottom of the flange provided around the top of the dosing bottom cover 200 is provided with two second magnets 240 matching the first magnet 140.

[0100] When the rotating body 100 stops at the feeding starting point, the two driving lugs 130 and the two positioning lugs 420 correspond to each other in up and down directions, respectively, and the two first magnets 140 and the two second magnets 240 also correspond to each other in up and down directions and are attracted to each other. The mutual attraction between the first magnet 140 and the second magnet 240 can ensure that the rotating body 100 accurately stops at the feeding starting point.

[0101] The working principle of the embodiment is as follows:

[0102] The medicine bottle is pre-filled with medicine. Before dispensing the medicine, the quantitative dispensing bottle cap of this embodiment is connected to the mouth of the medicine bottle through the internal thread of the feed top cap 400.

[0103] Then, the medicine bottle is inverted so that the positioning protrusion 420 of the feed top cover 400 is engaged in the arc-shaped slot of the external positioning device, and at the same time, the driving protrusion 130 of the rotating body 100 is engaged in the arc-shaped slot of the external driving device; that is, the feed top cover 400 is kept fixed, and the rotating body 100 can rotate clockwise or counterclockwise under the drive of the driving device.

[0104] In the initial position, the two first magnets 140 of the rotating body 100 and the two second magnets 240 of the feeding bottom cover 200 overlap and attract each other; at this time, the rotating body 100 stays at the feeding starting point, see Figure 12 The first wall surface 3111 is attached to the partition block 322, the volume of the metering cavity 3a is zero, and the first wall surface 3111 is also aligned vertically with the front wall 411 of the feed hole. The first rotation limiting structure 3211 is attached to one side of the second rotation limiting structure 230.

[0105] In a single dispensing process, the medicine in the medicine bottle must first enter the metering chamber 3a to achieve the metering purpose, and then the medicine in the metering chamber 3a is released to achieve the dispensing purpose. Afterwards, the rotating body 100, the first rotating component 310, and the second rotating component 320 are returned to their initial positions, thus completing one dispensing operation. The specific process is as follows:

[0106] First, the driving device drives the rotating body 100 to rotate a certain angle in the first clockwise direction (i.e., along the clockwise direction). Figure 12 (When rotating counterclockwise by a certain angle), during this process, the first rotation limiting structure 3211 will be blocked by the second rotation limiting structure 230, so the second rotating member 320 will remain stationary, while the first rotating member 310 will rotate counterclockwise together with the rotating body 100. Therefore, if... Figure 13 As shown, the distance between the first wall surface 3111 and the partition block 322 will gradually increase until the driving device stops driving the rotating body 100 to rotate. At this time, the rotating body 100 and the first rotating component 310 stop at the predetermined position of counterclockwise rotation, and the volume of the metering cavity 3a reaches the predetermined volume. During this process, the medicine in the medicine bottle will enter the metering cavity 3a through the feed hole 410 of the feed top cover 400 and fill the metering cavity 3a.

[0107] Then, the drive device drives the rotating body 100 to rotate in the second clockwise direction (i.e., along the clockwise direction). Figure 13clockwise direction), the second rotating member 320 will rotate with the first rotating member 310 and the rotating body 100 clockwise under the action of the elastic body 323 until the first rotation limiting structure 3211 rotates to the other side of the second rotation limiting structure 230, and the rotating body 100 reaches the starting point of the dispensing, as shown in Figure 14 illustrated, at this time, the side wall of the partition block 322 close to the first wall surface 3111 is aligned with the front wall 221 of the dispensing hole, and the metering cavity 3a is communicated with the dispensing hole 220, and the medicine in the metering cavity 3a begins to fall from the dispensing hole 220;

[0108] Then, the driving device continues to drive the rotating body 100 to rotate clockwise, and in this process, the first rotation limiting structure 3211 is blocked by the second rotation limiting structure 230, so that the second rotating member 320 remains stationary, and the first rotating member 310 rotates clockwise with the rotating body 100 until the first wall surface 3111 rotates to the partition block 322, at which time the driving device stops driving the rotating body 100 to rotate, as shown in Figure 15 illustrated, at this time, the rotating body 100 and the first rotating member 310 stop at the limit position of the clockwise rotation, and the volume of the metering cavity 3a becomes zero; in this process, since the volume of the metering cavity 3a gradually decreases, the medicine in the metering cavity 3a is gradually pushed by the first wall surface 3111 and then falls from the dispensing hole 220 until the volume of the metering cavity 3a becomes zero;

[0109] Finally, the driving device reverses to drive the rotating body 100 to rotate counterclockwise, and in this process, since the second rotation limiting structure 230 does not block the first rotation limiting structure 3211, the second rotating member 320 will rotate with the first rotating member 310 and the rotating body 100 clockwise under the action of the elastic body 323 until the rotating body 100, the first rotating member 310 and the second rotating member 320 return to the initial position, thereby completing a complete dispensing process.

[0110] In the above process, when the rotating body 100 rotates in the first clockwise direction from the starting point of the dispensing (i.e., from Figure 12The rotation position of the rotating body 100 determines the volume of the metering cavity 3a, and further determines the amount of the subsequent medicine. For example, the rotating body 100 rotates 30° or 45° in the first clockwise direction from the starting position of the feeding, and the amount of the medicine entering the metering cavity 3a is different, and thus the final amount of the medicine is different. Therefore, in the actual use process, the rotation angle of the rotating body 100 can be controlled by the driving device, and thus the predetermined volume of the metering cavity 3a can be controlled, and thus the amount of the single medicine can be controlled to meet the requirements of different medicine mixing ratios.

[0111] The preferred embodiments of the present application are described above, but the present application is not limited to the above. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
