Description

Technical Field

[0001] This utility model relates to the field of daily necessities, specifically a candy dispensing device. Background Technology

[0002] In existing technologies, candy dispensing devices are mainly divided into two categories: static container devices and trigger-based automatic devices. The basic design concept of static container devices is to place candy in an open container, allowing consumers to directly grab candy with their hands. However, this design has several drawbacks. First, because multiple people directly handle the candy, cross-contamination is highly likely, making hygiene difficult to guarantee. Second, this dispensing method makes it difficult to accurately control the amount of candy dispensed each time, especially since children often grab too much, potentially leading to waste and unnecessary disputes. Furthermore, the entire candy dispensing process lacks interactivity and fun; its use during holidays like Halloween significantly diminishes the festive experience and fails to meet people's expectations for a festive atmosphere. In contrast, trigger-based automatic devices use buttons, sensors, or other trigger mechanisms to initiate the candy dispensing process. This device solves the cross-contamination problem of static container devices to some extent, as consumers do not need to directly touch the candy. However, trigger-based automatic devices also have their limitations. First, these devices typically only support a simple binary trigger mode—either dispensing candy or not dispensing any—and cannot personalize candy dispensing according to the specific needs of consumers. Moreover, the device has a complex structure, high maintenance costs, and is difficult to apply widely. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0022] Example 1, as Figure 1-4 As shown, a candy dispensing device includes a base 1 and a top cover 2. The top cover 2 is fixedly installed on the top of the base 1. A storage chamber 3 is provided between the base 1 and the top cover 2. A conveying chamber 5 is fixedly installed below the storage chamber 3. The lower part of the storage chamber 3 is connected to the conveying chamber 5 through a discharge port 4. A candy outlet is opened on the front side of the base 1. The front end of the conveying chamber 5 is connected to the candy outlet. A screw propeller 6 is provided inside the conveying chamber 5. The rear end of the screw propeller 6 passes through the inner side of the conveying chamber 5 and is connected to the output shaft of a drive motor 7. The drive motor 7 is fixedly installed in the base 1. A feeding port 8 is opened on the upper surface of the top cover 2. A cap 9 is detachably installed on the feeding port 8.

[0023] An electronic mounting box 10 is fixedly installed inside the base 1. The electronic mounting box 10 contains a control circuit board 11, a microprocessor 12, and a power module 13. A camera 14 is fixedly embedded on the front side of the top cover 2. The signal output terminal of the microprocessor 12 is connected to the signal input terminal of the control circuit board 11 through a UART serial port. The signal output terminal of the camera 14 is connected to the data input terminal of the microprocessor 12 through a CSI interface. The signal output terminal of the control circuit board 11 is connected to the signal input terminal of the drive motor 7. The power module 13 is used to provide a stable power supply.

[0024] Working principle:

[0025] After the device is powered on and started, when someone approaches the device, the camera 14 can identify the person's face and clothing, and transmit the identification signal to the microprocessor 12 through the CSI interface. The microprocessor 12 processes the identification signal to determine whether it meets the set authorization conditions. In this embodiment, the microprocessor 12 can be a Raspberry Pi microcontroller, which runs a visual recognition model based on OpenCV and a clothing classifier trained with OpenCV Haarcascade and TensorFlow Lite, and can detect faces and clothing (this is existing technology and will not be described in detail). If the recognition is successful, the microprocessor 12 sends a command to the control circuit board 11. After receiving the command from the microprocessor 12, the control circuit board 11 controls the drive motor 7 to start through the built-in motor drive circuit (such as an H-bridge circuit). This drives the spiral propeller 6 to rotate, pushing the candy in the storage compartment 3 through the conveyor compartment 5 to the candy outlet, thus completing the automatic candy dispensing. Furthermore, during the rotation and pushing process of the screw propeller 6, the candy in the storage bin 3 is continuously replenished from the discharge port 4 into the conveying bin 5 to ensure a continuous candy supply. Additionally, a feeding port 8 is provided on the upper surface of the top cover 2, and a detachable cap 9 is installed on the feeding port 8. Therefore, when the candy in the storage bin 3 is insufficient, the cap 9 can be opened, and candy can be added to the storage bin 3 through the feeding port 8. The cap 9 ensures the airtightness of the storage bin 3, preventing the candy from getting damp or contaminated, thereby guaranteeing the quality of the candy.

[0026] In this embodiment, camera 14 accurately identifies users (e.g., those dressed in costumes matching Halloween decorations), ensuring the fun and safety of candy distribution, preventing accidental operation by unauthorized personnel, and improving user experience. Furthermore, by controlling the rotation of the screw propeller 6 driven by the drive motor 7, the candy is transported and distributed, effectively controlling the speed and quantity of candy distribution to ensure an appropriate amount of candy is given each time, avoiding waste. This also effectively enhances the fun and adds to the festive atmosphere.

[0027] In Embodiment Two, as a further preferred embodiment of Embodiment One, a speaker 15 is fixedly installed inside the base 1. The audio input terminal of the speaker 15 is connected to the output terminal of the control circuit board 11. A sound outlet 16 is opened on the side surface of the base 1, and the output terminal of the speaker 15 is opposite to the sound outlet 16. The microprocessor 12 has a built-in memory containing various pre-stored sound effect files. Therefore, when the microprocessor 12 successfully recognizes the files, it can directly call the stored sound effect data and send instructions to the control circuit board 11. After receiving the instructions from the microprocessor 12, the control circuit board 11 converts the microprocessor's digital audio signal into an analog signal through a built-in audio amplifier circuit (such as a Class D amplifier chip) to drive the speaker 15 to play preset welcome messages or fun sound effects, further enhancing the interactive experience, making the candy distribution process more vivid and interesting, and improving the overall event effect.

[0028] In Example 3, as a further preferred embodiment of Example 1, an eye frame 17 is fixedly embedded on the front side of the top cover 2. An LED light is fixedly installed inside the eye frame 17. The LED light is connected to the signal output terminal of the control circuit board 11. The control circuit board 11 controls the switching on and off of the LED light or PWM dimming through the built-in GPIO port. By controlling the LED light inside the eye frame 17 to light up, the effect of a real eye is simulated, adding to the robot's vividness. Furthermore, different modes can be distinguished by the different colors of the LED light. For example, orange represents a light mode, indicating that the spiral propeller 6 rotates half a turn each time, suitable for distributing a small amount of candy; blue represents a standard mode, indicating that the spiral propeller 6 rotates one revolution each time, suitable for distributing regular candy; and purple represents a fast mode, indicating that the spiral propeller 6 rotates two revolutions each time, suitable for distributing a large amount of candy, meeting the needs of different scenarios.

[0029] In Example 4, as a further preferred embodiment of Example 1, multiple conical supports 18 are fixedly connected to the lower surface of the inner cavity of the base 1. The conveying chamber 5, the drive motor 7, and the electronic mounting box 10 are all fixedly mounted on the conical supports 18. The conical supports 18 provide stable support for the conveying chamber 5, the drive motor 7, and the electronic mounting box 10, and ensure that the drive motor 7 and the electronic mounting box 10 can effectively dissipate heat, preventing overheating from affecting equipment operation and extending service life.

[0030] In Example 5, as a further preferred embodiment of Example 1, the power module 13 includes a power adapter and a voltage converter. The power adapter is connected to an external power source via a power cord, and its output terminal is connected to the input terminal of the voltage converter. The output terminal of the voltage converter is connected to the power input terminals of the control circuit board 11, microprocessor 12, drive motor 7, camera 14, speaker 15, and LED lights, respectively. The power adapter converts the external power source into the voltage required by the device, ensuring stable operation of each component. The voltage converter then converts the converted voltage into voltages suitable for each component, ensuring efficient operation of the device.

[0031] In Example 6, as a further preferred embodiment of Example 1, multiple hollow post 21s are vertically fixedly installed at the bottom of the inner cavity of the base 1. The central hole of each hollow post 21 penetrates the bottom of the base 1. A fixing screw 22 passes through each hollow post 21. A threaded post 23 is fixedly installed on the upper wall of the inner cavity of the top cover 2. The threaded post 23 is vertically aligned with the hollow post 21. The upper end of the fixing screw 22 passes through the fixing screw 22 and the storage compartment 3 in sequence and is threadedly connected to the threaded post 23. Therefore, when assembling or disassembling the device, the fixing screw 22 can be inserted into the hollow post 21 from the bottom of the base 1, and then passed upward along the axial direction of the hollow post 21 through the storage compartment 3 before being threadedly connected to the threaded post 23, thereby effectively ensuring a tight connection between the base 1 and the top cover 2. In this embodiment, a buffer pad can be provided between the base 1 and the top cover 2 to ensure the stability of the connection between the base 1 and the top cover 2.

[0032] In Example 7, as a further preferred embodiment of Example 1, the electronic mounting box 10 is provided with multiple partitions, which divide the electronic mounting box 10 into multiple independent spaces. The control circuit board 11, microprocessor 12, and power module 13 are all installed in their respective independent spaces. The partitions effectively isolate the various components, prevent electromagnetic interference, ensure the independent and stable operation of each module, and improve overall performance.

[0033] Specifically, the motor drive circuit, audio amplifier circuit, and LED light switching or PWM dimming circuit involved in the above embodiments all adopt well-known solutions in the prior art. The motor drive circuit, audio amplifier circuit, and LED light switching or PWM dimming circuit are all mounted on the control circuit board 11, which is already known to those skilled in the art and will not be described in detail here.

[0034] 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.
