Figure 2 As shown, the power amplifier circuit includes: pin 1 of the audio power amplifier chip U4 is respectively connected to one end of the resistor R11, one end of the resistor R13, one end of the capacitor C39, and one end of the resistor R12; pin 2 of the audio power amplifier chip U4 is respectively connected to one end of the capacitor C40 and one end of the resistor R16; the other end of the resistor R16 is respectively connected to pin 3 of the audio power amplifier chip U4 and one end of the resistor R17; the other end of the resistor R17 is connected to one end of the capacitor C41; pin 4 of the audio power amplifier chip U4 is respectively connected to One end of resistor R18, one end of resistor R19, and one end of capacitor C78 are connected, the other end of resistor R18 is connected to one end of capacitor C48, the other end of resistor R19 is respectively connected to pin 5 of audio power amplifier chip U4, one end of inductor L9, and the other end of capacitor C78, ​​the other end of inductor L9 is connected to the cathode of diode D3, pin 6 of audio power amplifier chip U4 is respectively connected to one end of capacitor C42 and one end of capacitor C43, and pin 8 of audio power amplifier chip U4 is connected to one end of inductor L8.

[0036] The power amplifier circuit is mainly used to amplify the audio signal so that it can drive the speaker to produce a loud enough sound. In the video feeder, the power amplifier circuit is connected to the audio and video processing chip and the speaker to play the owner's pre-recorded voice or the sound of a real-time call.

[0037] The working principle of a power amplifier circuit is based on the principle of electronic amplification. The audio signal first passes through a preamplifier for preliminary amplification before being sent to a power amplifier for high-power amplification. A power amplifier typically uses transistors or integrated circuits as amplification components, amplifying the voltage and current of the audio signal to a level sufficient to drive a speaker. In a video feeder, the power amplifier circuit receives the audio signal through an audio and video processing chip, amplifies it, and drives the speaker to produce sound, enabling voice communication with the pet.

[0038] In this embodiment, the power amplifier circuit can not only be used to play the preset voice prompt (such as "It's time to eat"), but also amplify the sound collected by the MIC when the owner is talking remotely, thereby realizing two-way voice communication.

[0039] The MIC is an audio signal input device used to collect ambient sounds, including the owner's voice commands and pets' calls. The collected audio signals are pre-processed and then transmitted to the audio and video processing chip for processing.

[0040] The antenna is the bridge between the video feeder and the outside world, responsible for receiving and sending wireless signals. Through the antenna, the video feeder can exchange data with mobile phone apps, cloud servers and other devices, realizing functions such as remote control, video viewing, and voice calls.

[0041] Figure 3 This is the circuit diagram of the power detection circuit in the 100W video feeder of this utility model. Figure 3 As shown, the power detection circuit includes: one end of the capacitor C79 is connected to one end of the resistor R46 and one end of the resistor R45 respectively, and the other end of the resistor R45 is connected to the battery BAT+.

[0042] The battery detection circuit monitors the battery level of the video feeder, ensuring that the device can promptly remind the user to recharge when the battery is low. This circuit detects the battery voltage or current and transmits this information to the audio and video processing chip. The audio and video processing chip then controls the LED indicator to display the corresponding status (such as a low battery warning) based on the battery level.

[0043] Figure 4 This is the circuit diagram of the LED and infrared fill light circuit in the 100W video feeder of this utility model. Figure 4 As shown, the LED and infrared fill light circuit includes: one end of the resistor R38 is connected to the pin LED+, the other end of the resistor R38 is respectively connected to one end of the capacitor C69 and one end of the capacitor C70, the pin LED- is connected to the drain of the transistor Q2, the gate of the transistor Q2 is respectively connected to one end of the resistor R39 and one end of the resistor R40, the source of the transistor Q2 is grounded, the pin LED+ is connected to the positive electrode of the LED lamp, and the pin LED- is connected to the negative electrode of the LED lamp.

[0044] LED circuits provide lighting and status indication. In video feeders, LEDs are often used to illuminate the feeding area, enhancing video clarity. LEDs can also serve as status indicators, displaying the device's operating status (such as connection status and battery level). Infrared fill light circuits provide infrared light at night or in low light conditions, enhancing the camera's night vision.

[0045] Figure 5 This is the circuit diagram of the key circuit in the 100W video feeder of this utility model. Figure 5 As shown, the key circuit includes: one end of the key resistor S1 is respectively connected to one end of the resistor R35, one end of the capacitor C66, and one end of the diode D12.

[0046] The key circuit is the interface for users to interact with the video feeder, including buttons for setting the feeding time, adjusting the feeding amount, and starting / stopping feeding. The key circuit transmits user operation instructions to the audio and video processing chip, which then controls other components to perform corresponding operations based on the instructions.

[0047] Figure 6 This is the red and blue indicator circuit diagram of the 100W video feeder of this utility model. Figure 6 As shown, the red and blue indication circuit includes: one end of a resistor R41 is connected to one end of a resistor R42, the other end of the resistor R41 is respectively connected to pin 2 of a diode D15 and pin 2 of a diode D17, pin 1 of a diode D15 is respectively connected to one end of a resistor R49, the collector of a transistor Q3, pin 1 of a diode D16, and pin 1 of a diode D17, pin 3 of a diode D15 is respectively connected to pin 3 of a diode D16, pin 3 of a diode D17, one end of a resistor R52, and the collector of a transistor Q4, the other end of the resistor R52 is connected to one end of a resistor R51, the other end of the resistor R51 is respectively connected to one end of a resistor R50 and the base of a transistor Q4, and the base of the transistor Q3 is respectively connected to one end of a resistor R49 and one end of a resistor R47.

[0048] Red and blue indicator circuits are often used to display different working states of video feeders. For example, a red indicator light may indicate that the device is charging or has a fault, while a blue indicator light may indicate that the device is connected to the network or is in normal working condition.

[0049] The first motor drives the dial on the feeder's turntable to rotate and feed the food. When the audio and video processing chip receives a feeding command, it activates the first motor, rotating the dial and dropping food from the storage bin into the feeding bowl. The second motor controls the turntable and camera to rotate left and right, as well as up and down, enabling comprehensive monitoring and feeding.

[0050] Figure 7 This is the circuit diagram of the DC-DC step-down circuit in the 100W video feeder of this utility model. Figure 7 As shown, in a specific implementation, the video feeder further includes: a DC-DC step-down circuit, which is connected to the audio and video processing chip. The DC-DC step-down circuit includes: pin 4 of the monolithic step-down switching regulator chip U3 is respectively connected to one end of capacitor C34 and one end of capacitor C35, pin 5 of the monolithic step-down switching regulator chip U3 is respectively connected to one end of capacitor C36, one end of resistor R9, and one end of resistor R10, pin 3 of the monolithic step-down switching regulator chip U3 is connected to one end of inductor L7, the other end of inductor L7 is respectively connected to the other end of capacitor C36, the other end of resistor R9, one end of capacitor C37, one end of capacitor C77, and one end of capacitor C38, the other end of capacitor C34, the other end of capacitor C35, the other end of resistor R10, the other end of capacitor C37, the other end of capacitor C77, and the other end of capacitor C38 are all grounded.

[0051] The DC-DC step-down circuit converts the high-voltage DC power supply inside the video feeder into a low-voltage DC power supply to meet the power supply needs of various electronic components, such as the audio and video processing chip BK7256. For example, it converts the input 12V DC power supply into a low-voltage power supply such as 5V or 3.3V to supply components such as the audio and video processing chip and the camera.

[0052] Figure 8 This is the DC-DC circuit diagram of the 100W video feeder of this utility model. Figure 8 As shown, in a specific implementation, the video feeder further includes: a DC-DC circuit, which is respectively connected to the DC-DC step-down circuit and the camera. The DC-DC circuit includes: pin 1 of the monolithic step-down switching regulator chip U2 is respectively connected to one end of capacitor C30 and one end of capacitor C31, pin 3 of the monolithic step-down switching regulator chip U2 is connected to one end of resistor R7, pin 5 of the monolithic step-down switching regulator chip U2 is respectively connected to one end of capacitor C32 and one end of capacitor C33, and the other end of capacitor C30, the other end of capacitor C31, the other end of capacitor C32, and the other end of capacitor C33 are all grounded.

[0053] The DC-DC circuit can be used to power audio and video processing chips.

[0054] Figure 9 This is the circuit diagram of the filter switching circuit in the 100W video feeder of this utility model. Figure 9As shown, in a specific implementation, the video feeder also includes: a filter switching circuit (IR-CUT), which is connected to the audio and video processing chip. The filter switching circuit includes: Pin 5 of the DC brush motor driver chip U5 is connected to one end of capacitor C53 and one end of capacitor C54, respectively; Pin 4 of the DC brush motor driver chip U5 is connected to one end of resistor R23; Pin 3 of the DC brush motor driver chip U5 is connected to one end of resistor R24; Pin 6 of the DC brush motor driver chip U5 is connected to one end of capacitor C55; Pin 1 of the DC brush motor driver chip U5 is connected to the other end of capacitor C55. In a specific implementation, the DC brush motor driver chip U5 is selected as BDR6120S.

[0055] The IR-CUT operates based on the different transmission characteristics of infrared and visible light through optical lenses. Its core components typically consist of two filters: an infrared cutoff or absorption filter and a full-spectrum transmittance filter. These two filters are switched by a power source (such as an electromagnet or motor). This power source is controlled by the BDR6120S, enabling precise positioning and switching of the filters.

[0056] During bright daylight hours, the BDR6120S drives the switch to position the infrared cutoff filter. This filter effectively blocks infrared light while allowing nearly complete transmission of visible light, ensuring the camera captures true color images without the interference of infrared light on color reproduction.

[0057] At night or in low light, the infrared cutoff filter automatically moves away, allowing the full-spectrum filter to kick in. This filter allows both infrared and visible light to pass through simultaneously. Combined with the supplemental infrared light source, the camera can fully utilize all available light for imaging, significantly enhancing night vision and providing clearer, more natural-looking images.

[0058] IR-CUT realizes automatic switching between color images during the day and black-and-white images at night without human intervention. It not only improves image quality and color reproduction, but also greatly enhances the adaptability and practicality of the camera, playing an important role in surveillance cameras, mobile phone cameras and other fields.

[0059] The working principle of the utility model video feeder is:

[0060] When the video feeder is powered on, it first performs initialization operations, including self-test, program loading, network connection, etc. After initialization is completed, the device enters standby mode, waiting for user instructions or the preset feeding time to arrive.

[0061] When the preset feeding time arrives or the user sends a feeding command via the app, the audio and video processing chip receives the command and first checks the device status (such as sufficient battery and network connection). If everything is normal, it controls the first motor to start, driving the dial on the feeder's turntable to feed the baby. At the same time, the audio and video processing chip also controls the motor's operating time based on the preset feeding amount to ensure accurate feeding.

[0062] During the feeding process or at any time, users can remotely view the video feeder's real-time image through the app. The video signal captured by the camera is processed by the audio and video processing chip and then transmitted via the antenna to the mobile app or cloud server. Users can also send voice commands to the video feeder through the app, enabling remote calls or voice control.

[0063] At night or in low light conditions, the infrared fill light circuit automatically activates to provide infrared light for the camera. This infrared light is captured by the camera and processed by an image processing algorithm, resulting in a clear black and white image on the screen. This allows you to clearly see your pet's activities even at night.

[0064] The battery detection circuit monitors the battery level of the video feeder in real time and transmits this information to the microprocessor. When the battery level falls below a preset threshold, the audio and video processing chip controls the LED indicator to flash as a low-battery warning and reminds the user through the app to charge the device in time.

[0065] The button circuit allows users to configure and operate the video feeder in various ways, such as setting the feeding time, adjusting the feeding amount, and starting / stopping feeding. Furthermore, the red and blue indicator circuit displays the corresponding indicator light color according to the device's different operating states, allowing users to easily understand the device's current status.
