Further, the slave driving module 330 further includes a sleeve 332, a spring member 334 and a fixing member 335. The two sleeves 332 are respectively sleeved on two free ends of the second rotating shaft 333 and located at two sides of the second sprocket 331. Each sleeve 332 includes a cylindrical body 3321 sleeved on the second rotating shaft 333, and a free end 3322 extending from the outer wall of the cylindrical body 3321 in the radial direction of the cylindrical body 3321. The fixing member 335 is received in the annular space 201 and fixed to the housing 100, and the free end 3322 of the sleeve 332 is slidably connected to the fixing member 335 along the extending direction of the free end 3322. The spring 334 is disposed on the free end 3322 of the sleeve 332, and two ends of the spring are respectively abutted against the barrel 3321 of the sleeve and the fixing element 335. When a pulling force is generated in a radial direction during the rotation of the driven module 330, the sleeve 332 and the spring member 334 are deformed to counteract the pulling force. When a compressive force is generated in a radial direction during rotation of the driving module 330, the sleeve 332 and the spring member 334 are deformed to cancel the compressive force. Thus, the drug delivery structure 200 can be made to rotate tightly around the master drive module 310 and the slave drive module 330.

The source drive module 300, the transmission module 320 and the main drive module 310 are sequentially arranged in a hollow space formed by the drug delivery structure 200; wherein, the first chain wheel 311 of the main driving module 310 is attached to the medicine conveying structure 200. Since the tooth grooves and the teeth of the first sprocket 311 are arranged to be completely matched with the first connecting column 213, the second connecting column 223, the first short bottom surface 212 and the second short bottom surface 222 of the medicine conveying structure 200, the medicine conveying structure 200 can be driven to rotate around the main driving module 310 when the main driving module 310 rotates. For more stable rotation of the drug delivery structure 200, a slave drive module 330 is provided at the other end of the drug delivery structure 200. Wherein the second sprocket 331 of the slave drive module 330 is structurally identical to the first sprocket 311. Therefore, the second sprocket 331 can also drive the drug delivery structure 200 to rotate around the main driving module 310.

The drug delivery device further comprises a first bottom cover 120 and a second bottom cover (not shown), wherein the first bottom cover 120 is disposed on a side of the drug delivery structure 200 facing the opening of the receiving cavity 101 and covers a side surface formed when the drug delivery structure 200 rotates around the main driving module 310; the second bottom cover is arranged on one side of the medicine conveying structure 200 departing from the opening of the accommodating groove 101 and covers the side surface formed when the medicine conveying structure 200 rotates around the main driving module 310; that is, the first bottom cover 120 and the second bottom cover respectively cover both side surfaces of the annular space 201 in one-to-one correspondence.

Referring back to fig. 1 to 3, the photoelectric sensor 400 is accommodated in the annular space 201, and includes a transmitter 410 and a receiver 420, wherein the transmitter 410 and the receiver 420 are spaced apart from each other along a direction perpendicular to the cross-sectional profile of the annular space 201. The above-mentioned light barrier 240 is located between the emitter 410 and the receiver 420 in a direction perpendicular to the cross-sectional profile of the annular space 201. The light barrier 240 is used to extend between the transmitter 410 and the receiver 420 during the movement of the drug delivery structure 200 to block the transmitter 410, i.e. to prevent the receiver 420 from receiving the optical signal transmitted by the transmitter 410; the photosensor 400 is used to measure the number of times the emitter 410 is blocked by the flag 240 during unidirectional movement of the drug delivery structure 200.

In addition, the drug delivery device further includes a controller, not shown, which is connected to the source driving module 300 and the photo sensor 400, respectively, so that the controller can obtain the number of times the emitter 410 is blocked, and determine that the drug delivery structure 200 has traveled an integral multiple of the set displacement corresponding to the number of times.

The embodiment of the utility model provides a drug delivery device includes shell 100, drug delivery structure 200, source drive module 300, photoelectric sensor 400 and controller. The drug delivery structure 200 is accommodated in the housing 100 and encloses an annular space 201, a plurality of accommodating spaces 202 are uniformly arranged along the contour of the annular space 201 at intervals on one side of the drug delivery structure facing away from the annular space 201, a plurality of light blocking plates 240 are uniformly arranged along the contour of the annular space 201 at intervals on one side of the drug delivery structure facing towards the annular space 201, and the light blocking plates 240 correspond to the accommodating spaces 202 one to one. The light barrier 240 is configured to extend between the emitter 410 and the receiver 420 during movement of the drug delivery structure 200 to block the emitter 410, thereby facilitating the photoelectric sensor 400 to measure the number of times of blocking by the emitter 410. The controller is also configured to obtain the number of times the emitter 410 is blocked by the flag 240 during unidirectional movement of the drug delivery structure 200.

Since the receiving spaces 202 and the light blocking plates 240 are uniformly distributed along the cross-sectional profile of the annular space 201 at intervals and are in one-to-one correspondence, one light blocking plate 240 blocks the emitter of the photoelectric sensor 400 once for each set displacement of the drug delivery structure 200 per unit of travel. Thus, the present drug delivery device may monitor whether the drug delivery structure 200 has traveled an integer multiple of the set displacement via the photoelectric sensor; and then the controller can accurately control the source driving module to operate in due time, so that the medicines in the accommodating spaces 202 can orderly move to the medicine outlet 102 to realize material dropping.

It should be understood that even if the source drive module 300, the transmission module 320 and the primary drive module 310 in the above described embodiment drive the movement of the drug delivery structure 200, it is: the source driving module 300 indirectly drives the drug delivery structure 200 to move through a transmission module 320 and the main driving module 310, but the present invention is not limited thereto; in other embodiments of the present invention, only the source driving module may be included. For example, in some embodiments, the source driving module includes a motor and the first sprocket mounted at an output end of the motor, which can also be implemented.

Please refer to fig. 9, which is a schematic perspective view of a medicine cabinet 10 according to an embodiment of the present invention, and is combined with fig. 1 to 8; the cabinet frame 11 is provided with a storage space, and the drawer unit 12 is slidably mounted on the cabinet frame 11 and can extend out of or retract into the storage space; the drawer units 12 are arranged in sequence from top to bottom as shown in the figure to form a medicine cabinet 10 with multiple layers of drawer units 12. Wherein each drawer unit 12 comprises a drawer rack (not shown) and at least one of the above-mentioned drug delivery devices mounted to the drawer rack; the worker may access the drug delivery device by pulling the drawer unit 12. It is worth mentioning that "a plurality" in this application means more than two. Of course, in other embodiments of the present application, the number of the drawer units 12 may be only one.

Because the medicine conveying device is included, the medicine cabinet 10 provided by the embodiment of the present invention can also monitor whether the medicine conveying structure 200 moves by an integral multiple of the set displacement through the photoelectric sensor; and then the controller can accurately control the source driving module to operate in due time, so that the medicines in the accommodating spaces 202 can orderly move to the medicine outlet 102 to realize material dropping.
