Description

Technical Field

[0001] This utility model relates to the field of smart pillbox technology, and in particular to a smart pillbox with dual detection and positioning. Background Technology

[0002] A smart pillbox is a pillbox that incorporates smart technology to help users better manage their medications. It reminds users to take their medications on time via sound, light, or mobile phone notifications, and has multiple compartments for categorizing and storing different medications.

[0003] Smart pillboxes include, but are not limited to, a casing, a display screen, a divided pill tray, and a transmission mechanism. Medication is placed in the divided pill tray, and the transmission mechanism drives the tray to rotate periodically, ensuring that the designated pill compartment is precisely aligned with the dispensing spout. In existing technologies, the position detection of the divided pill tray mainly relies on infrared positioning components, which determine whether the pill compartment has reached the predetermined dispensing position by observing the state of infrared signal blocking or reflection. However, this technical solution has a significant drawback: the infrared component is susceptible to interference from ambient light, especially the overlap between the near-infrared band of sunlight and the spectrum of artificial infrared light sources, causing abnormal fluctuations in the receiver signal and leading to misjudgments of the pill tray position.

[0004] In strong light environments, the infrared signal strength may be attenuated or stray light may interfere, causing the transmission mechanism to misjudge the position of the medicine tray. This may trigger the medicine tray to rotate too much or too little. When the actual position of the medicine tray deviates from the position determined by the system, the patient may have to take the medicine repeatedly, resulting in overdose or missed doses due to misplaced medicine compartments. This poses a health threat, especially to elderly patients and patients with chronic diseases who need to take medication at regular intervals and in specific amounts. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a smart pillbox with dual detection and positioning, which can effectively solve the problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0007] According to one aspect of the present invention, a control module for driving the rotation of a medicine tray is included. The control module includes a medicine tray transmission mechanism and a gear set. The medicine tray transmission mechanism cooperates with the gear set to drive the medicine tray to rotate. The control module also includes a sensing element, which is assembled on the gear set and rotates through the gear set. The sensing element has symmetrical notches formed at both ends, one of which is equipped with an infrared sensing component for detecting the rotation position of the medicine tray. The control module also includes at least one Hall sensor assembly for detecting the rotation position of the medicine tray, which is assembled between the two notches.

[0008] Furthermore, the infrared sensing component includes an infrared receiver and an infrared emitter, which are located on the inner and outer sides of one of the notches, respectively.

[0009] Furthermore, there are two Hall sensor assemblies, which are symmetrically assembled between the two notches.

[0010] Furthermore, the Hall sensor assembly includes a Hall sensor and a magnet, with two magnets symmetrically fixedly embedded in the sensing element, and two Hall sensors respectively disposed above the two magnets.

[0011] Furthermore, it also includes a circuit board, which is placed over the sensing element. The infrared receiver and infrared emitter are located below the circuit board, and two Hall sensors are located above the circuit board. The circuit board is equipped with a microprocessor for controlling the rotation and stopping of the motor in the gear set. The infrared receiver, infrared emitter, and the two Hall sensors are all connected to the microprocessor.

[0012] Furthermore, it also includes a lower housing, a top cover, and a sliding plate. The top cover is rotatably disposed on the lower housing and has a medicine outlet. The sliding plate is movably disposed on the top cover and has at least two slide rails. The two ends of the top cover extend toward the two slide rails and are provided with limiting protrusions. The two slide rails cooperate with the two limiting protrusions to cover and expose the medicine outlet.

[0013] Furthermore, it also includes a magnifying glass for magnifying the drug indicator ring, the magnifying glass being arranged in a ring around the top cover.

[0014] By adopting the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0015] Firstly, by combining infrared sensing and Hall sensor dual detection technology, the collaborative work of two sensors based on different principles significantly reduces the risk of misjudgment caused by environmental interference such as strong light or abnormal magnetic fields. When the infrared signal is interfered with, the Hall sensor can still complete the positioning independently, and vice versa, ensuring stable operation of the system in complex environments, improving positioning accuracy, and avoiding over-rotation, under-rotation, or jamming.

[0016] Secondly, by incorporating a magnifying glass, the elderly can clearly see the medication indicator ring, reducing medication errors.

[0017] Thirdly, the adoption of a dual-slide rail structure provides more stable support and guidance, ensuring that the slider 81 maintains precise position control during movement, effectively avoiding problems such as jamming or deviation, and improving the reliability and stability of use. Furthermore, the dual slide rails can distribute the force, reducing wear on individual slide rails, thereby extending the service life of the entire medicine box structure. In addition, the dual-slide rail design enhances the symmetry and balance of the structure, making the slider more evenly and tightly positioned when covering and exposing the medicine opening, further improving the sealing performance and protective effect of the medicine box, better protecting the medicine from external environmental influences, and ensuring the safety of medicine storage and ease of use.

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are only for illustrating the present invention and do not limit the scope of the present invention. Similarly, the following embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0028] like Figures 1 to 7 As shown, this solution provides a smart pillbox with dual detection and positioning.

[0029] Please see Figure 1 , Figure 5 , Figure 6 and Figure 7 The box includes a lower housing 9, a top cover 8, and a slider 81. The top cover 8 is rotatably mounted on the lower housing 9 and has a medicine outlet 80. The slider 81 is movably mounted on the top cover 8 and has at least two slide rails 811. Limiting protrusions 82 extend from both ends of the top cover 8 toward the two slide rails 811. The two slide rails 811 cooperate with the two limiting protrusions 82 to cover and expose the medicine outlet 80. This dual-slide rail structure provides more stable support and guidance, ensuring that the slider 81 maintains precise position control during movement, effectively avoiding jamming or offset problems, and improving reliability and stability. Furthermore, the dual slide rails can distribute force, reducing wear on individual slide rails and extending the service life of the entire medicine box structure. In addition, the dual-rail design enhances the symmetry and balance of the structure, making the slide plate 81 more uniform and tighter when covering and exposing the medicine opening 80, further improving the sealing performance and protective effect of the medicine box, better protecting the medicine from the influence of the external environment, and ensuring the safety of medicine storage and the convenience of use.

[0030] It also includes a control module 100 for driving the rotation of a medicine tray (not shown). The control module 100 includes a medicine tray transmission mechanism 1 and a gear set 2. The medicine tray transmission mechanism 1 and the gear set 2 cooperate to drive the medicine tray to rotate. The medicine tray transmission mechanism 1 and the gear set 2 are direct applications of existing technology, and their working principle will not be described in detail here. It also includes a cover plate 4, which is placed on top of the control module 100.

[0031] Please see Figure 7 It also includes a magnifying glass 10 for magnifying the medication indicator ring, which is arranged in a ring around the top cover 8. Specifically, the medication indicator ring for the daily dosage is affixed to the medicine tray. By setting up the magnifying glass 10, the elderly can easily see the medication indicator ring and reduce medication errors.

[0032] Please see Figures 1 to 6 It also includes a sensor 21, which is mounted on a gear set 2. The gear set 2 drives the sensor 21 to rotate. The sensor 21 has symmetrical notches 22 at both ends. One of the notches 22 is equipped with an infrared sensing component 7 for detecting the rotation position of the medicine tray. The infrared sensing component 7 includes an infrared receiving tube 71 and an infrared emitting tube 72, which are located on the inner and outer sides of one of the notches 22, respectively.

[0033] It also includes at least one Hall sensor assembly 5 for detecting the rotational position of the medicine tray. Preferably, there are two Hall sensor assemblies 5, which are symmetrically assembled between the two notches 22. The Hall sensor assembly 5 includes a Hall sensor 51 and a magnet 52. The two magnets 52 are symmetrically fixed and embedded in the sensing element 21, and the two Hall sensors 51 are respectively disposed above the two magnets 52.

[0034] It also includes a circuit board 3, which is placed on top of the sensing element 21. An infrared receiver 71 and an infrared emitter 72 are placed below the circuit board 3, and two Hall sensors 51 are placed above the circuit board 3. A microprocessor for controlling the rotation and stopping of the motor in the gear set 2 is provided on the circuit board 3. The infrared receiver 71, the infrared emitter 72, and the two Hall sensors 51 are all connected to the microprocessor.

[0035] Working principle:

[0036] Initial positioning detection: When the notch 22 is aligned with the infrared sensing component 7, the signal emitted by the infrared emitting tube 72 is normally received by the infrared receiving tube 71, and the microprocessor determines that the division of the medicine tray is aligned with the medicine outlet 80. At the same time, two Hall sensors 51 detect the magnetic field position of two magnets 52. The two magnets 52 are symmetrically embedded in the sensing element 21. When the magnets 52 rotate to be directly below the Hall sensors 51, the Hall sensors 51 output a signal. The microprocessor combines the infrared signal and the Hall signal to double confirm the initial position of the medicine tray.

[0037] Medicine tray rotation control: The microprocessor starts the motor in gear set 2, driving the medicine tray transmission mechanism 1 to rotate the medicine tray. The sensor 21 rotates synchronously with gear set 2, and the positions of notch 22 and magnet 52 change accordingly. The infrared sensing component 7 monitors the passage status of notch 22 in real time: when notch 22 deviates from the infrared sensing component 7, the infrared signal is blocked, triggering the microprocessor to record the rotation angle. The microprocessor then triggers the motor of gear set 2 to reverse or continue rotating, thereby positioning the medicine tray. Two Hall sensors 51 synchronously detect the magnetic field changes of magnet 52: for every half-turn rotation of sensor 21, the corresponding medicine tray rotates one unit. Magnet 52 passes through the two Hall sensors 51 in sequence, outputting periodic pulse signals. When the infrared receiver tube 71 detects that notch 22 has passed again (infrared signal recovery) and both Hall sensors 51 receive the trigger signal from magnet 52, the microprocessor determines that the medicine tray has accurately rotated one unit and immediately stops the motor. If the infrared signal fails due to ambient light interference, the two Hall sensors 51 can still determine the position of the medicine tray by the magnetic field changes of magnet 52, and vice versa. The dual detection mechanism ensures that the system continues to operate reliably even if one side fails.

[0038] Each time the medicine tray rotates one division, the sensor 21 rotates half a circle synchronously. The periodic positional changes of the notch 22 and the magnet 52 correspond one-to-one with the division of the medicine tray. The dual detection signals of the infrared sensor component 7 and the Hall sensor component 5 are integrated by the microprocessor of the circuit board 3 to realize closed-loop control of the rotation of the medicine tray, ensuring that the division is accurately aligned with the medicine outlet 80, and avoiding over-rotation, under-rotation or jamming.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
