[0025] Example 1

[0026] like Figures 1-3As shown in the figure, the drug delivery device with stable rotation speed proposed in this embodiment includes a bottom shell 1, an upper cover 2, a controller 3, an annular turntable 5, a feeding pipe 10, and a power component.

[0027] The bottom of the bottom shell 1 is provided with multiple support feet 15; the top cover 2 is rotatably mounted on the bottom shell 1. The top cover 2 is made of tempered glass, so that the patient can see the remaining amount of medicine stored inside the annular turntable 5 through the top cover 2; the top cover 2 has a circular hole 201, and the movable end of the top cover 2 has a detachable connection structure with the bottom shell 1; the movable end of the top cover 2 is connected to an elastic piece 4, and the end of the elastic piece 4 is provided with a wedge block 41. The bottom shell 1 is provided with a buttonhole 16 for the elastic piece 4 to be inserted, and a groove for limiting the wedge block 41 is provided in the buttonhole 16.

[0028] The annular turntable 5 is rotatably mounted on the inner side of the bottom shell 1. Multiple material holes 501 are equidistantly opened on the annular turntable 5. The power component is installed at the bottom center of the inner side of the bottom shell 1 and is used to drive the annular turntable 5 to rotate. The power component includes a servo motor, a gear and a gear ring. The gear is mounted on the output shaft of the servo motor, and the gear ring is mounted on the annular turntable 5 and meshes with the gear.

[0029] The controller 3 is located at the upper middle part of the inner side of the bottom shell 1. The controller 3 is a PLC controller or a microcontroller. The controller 3 is equipped with a display screen, control buttons and an alarm.

[0030] The feeding tube 10 is located at the bottom end of the bottom shell 1 and communicates with the inner side of the bottom shell 1. A rotating base plate 12 is rotatably installed at the bottom end of the feeding tube 10. The cross-section of the rotating base plate 12 is U-shaped. The purpose of this design is to prevent the medicine from slipping off the sides of the rotating base plate 12. An elastic band 14 connects the rotating base plate 12 and the bottom shell 1. An L-shaped pressure rod 13 is connected to the movable end of the rotating base plate 12. When taking the medicine, the patient should turn their palm upward and press the back of their fingers downward to push the L-shaped pressure rod 13, causing the rotating base plate 12 to flip downward. Then the medicine rolls directly into the patient's palm, improving the convenience of taking the medicine.

[0031] Specifically, before use, the medication that the patient needs to take for several consecutive days should be placed in the dispenser. Before placing the medication, the top cover 2 should be rotated open, and then the medication should be placed into the inside of the multiple feed holes 501 in sequence. During the dispensing process, attention should be paid to the dispensing order and the rotation direction of the annular turntable 5.

[0032] The number of times and the time of medication to be taken each day are then set via controller 3. The time is displayed on the screen of controller 3. When the set time is reached, controller 3 controls the alarm to sound to remind the patient to take the medication on time. During this process, the annular turntable 5 is driven to rotate by the set power component. The single rotation angle of the annular turntable 5 is 360 / N (N is the number of feed holes 501). At this time, the medication to be taken rotates to the top of the feed pipe 10 and falls into the inside of the feed pipe 10. The operator rotates the rotating base plate 12 downwards to make the medication inside the feed pipe 10 discharged.

[0033] Example 2

[0034] like Figure 1 and Figure 2 As shown, this embodiment proposes a drug delivery device with stable rotation speed. Compared with the first embodiment, in this embodiment, the upper cover 2 is provided with a desiccant box 7, the desiccant box 7 is detachably provided with a cover 8, the inner side of the desiccant box 7 is provided with desiccant particles, and the desiccant box 7 is provided with several fine holes; the desiccant inside the desiccant box 7 can absorb the moisture inside the bottom shell 1, and prevent the drugs stored inside the bottom shell 1 from getting damp.

[0035] Example 3

[0036] like Figure 2 As shown, this embodiment proposes a drug delivery device with stable rotation speed. Compared with Embodiment 1, in this embodiment, a first sealing ring 6 and a second sealing ring 9 are installed on the inner side of the upper cover 2. The first sealing ring 6 is located on the outer periphery of the circular hole 201, and the second sealing ring 9 is located on the outer periphery of the upper cover 2. The arrangement of the first sealing ring 6 and the second sealing ring 9 can enhance the sealing between the upper cover 2 and the bottom shell 1. It should be noted that after the upper cover 2 is closed, the first sealing ring 6 is pressed against the outer periphery of the controller 3. A third sealing ring is provided at the bottom end of the feed pipe 10. The arrangement of the third sealing ring can enhance the sealing between the feed pipe 10 and the rotating base plate 12, and prevent moisture from entering the interior of the bottom shell 1 through the feed pipe 10.

[0037] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
