Technical Field
[0001] This utility model relates to the technical field of circuit structure for visual ear spoons, and in particular to a circuit structure for a visual ear spoon. Background Technology
[0002] An ear pick typically consists of a long, thin handle and a small spoon at the end of the handle; it's a tool specifically designed for removing earwax. In daily life, we need to clean our ears periodically.
[0003] Ear picks are a common ear cleaning tool that is inserted into the ear canal through the tip to clean earwax inside the ear canal. When using an ear pick, if the user operates it himself, he cannot observe the condition inside the ear canal, and it is easy to scratch the ear canal during operation, making it inconvenient to use.
[0004] Later, ear-cleaning devices combining cameras and ear picks appeared on the market, allowing for visualization of the inside of the ear. However, existing visual ear picks have the following drawbacks:
[0005] 1. It lacks battery life and can only be powered by constantly replacing batteries;
[0006] 2. To view images captured by the camera, you need to download an app, which will take up memory on your phone.
[0007] Therefore, in this utility model patent application, the applicant has carefully studied a circuit structure for a visual ear spoon to solve the above problems. Utility Model Content
[0008] This invention addresses the shortcomings of the existing technology by providing a circuit structure for a visual ear pick. Users can view images captured by a camera in real time via a WeChat mini-program on a mobile terminal, eliminating the need to download a corresponding app and greatly improving the user experience. Furthermore, the microcontroller circuit is used to wake up the Bluetooth master control module, significantly reducing the power consumption of the Bluetooth master control module.
[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0017] As a preferred embodiment, it also includes a rechargeable battery, a first power supply circuit for providing a 2.8V voltage, and a second power supply circuit for providing a 3.3V voltage;
[0018] The rechargeable battery is connected to the first power supply circuit and the second power supply circuit respectively.
[0019] As a preferred embodiment, it also includes a charging interface, which is connected to a rechargeable battery via a charging circuit.
[0020] This utility model has significant advantages and beneficial effects compared with the prior art, specifically:

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0035] like Figure 1 and Figure 2 As shown, a circuit structure for a visual ear pick includes a microcontroller circuit 12, a camera 15, a power button 11, a memory 14, and a Bluetooth main control module 13 for wirelessly connecting to a cloud server 20; the cloud server 20 is used for signal connection to a mobile terminal 30. The mobile terminal 30 can be one of a smartphone, tablet, laptop, or smartwatch, and the mobile terminal 30 can install WeChat mini-programs.
[0036] The microcontroller circuit 12 is connected to the power button 11 and the Bluetooth master control module 13 respectively so that when the power button 11 (also known as button K1 in the figure) is pressed, a power-on signal is sent to the Bluetooth master control module 13. In this embodiment, the power-on and power-off are completed by the microcontroller circuit 12 alone, which helps to reduce the power consumption of the Bluetooth master control module 13.
[0037] In this embodiment, the microcontroller circuit 12 is composed of a chip U5 with model number Jiuqi 050D and its peripheral circuits.
[0038] The Bluetooth master control module 13 is connected to the memory 14 and the camera 15 respectively to process the image data captured by the camera 15 and store it on the memory 14 and the cloud server 20 respectively.
[0039] The mobile terminal 30 completes pairing by scanning a QR code (which can be placed on the packaging box of the visual ear pick, or provided by the seller; this is not a limitation) via a WeChat mini-program. By loading the WeChat mini-program onto the mobile terminal 30, a signal connection is established between the WeChat mini-program and the Bluetooth main control module 13. The mobile terminal 30 can then use the WeChat mini-program to view the image information captured by the camera 15 in real time.
[0040] In this embodiment, the Bluetooth master control module 13 is connected to the camera 15 via interface J2.
[0041] The Bluetooth main control module 13 is connected to an indicator light circuit 16, through which the usage status of the visual ear spoon can be intuitively understood.
[0042] The Bluetooth master control module 13 consists of a PAAU1603 chip U1 and its peripheral circuitry. Chip U1 is a chip with a built-in MCU and Bluetooth chip, exhibiting a high degree of integration and a simple circuit structure design, significantly reducing the manufacturing cost of this product.
[0043] Pin 2 of chip U1 is connected to cloud server 20. Pin 23 of chip U1 is connected to indicator light circuit 16. Pins 10 to 22, 36, and 37 of chip U1 are all connected to interface J2. Pins 26 and 25 of chip U1 are connected to memory 14.
[0044] It also includes a rechargeable battery 17, a charging interface 171, a first power supply circuit 181 for providing a 2.8V voltage, and a second power supply circuit 182 for providing a 3.3V voltage;
[0045] The rechargeable battery 17 is connected to the first power supply circuit 181 and the second power supply circuit 182. In this embodiment, the first power supply circuit 181 is composed of a chip U3 (model LP3987H-28) and its peripheral circuits, and the second power supply circuit 182 is composed of a chip U4 (model LP3987H-33) and its peripheral circuits. The enable terminals of chips U3 and U4 are both connected to pin 1 of chip U5 of microcontroller circuit 12. When the power button 11 is pressed, pin 1 of chip U5 of microcontroller circuit 12 sends a signal to the enable terminals (i.e., pin 3) of chips U3 and U4, thereby triggering the first power supply circuit 181 to output a 2.8V voltage and the second power supply circuit 182 to output a 3.3V voltage.
[0046] The charging interface 171 (USB1 in the figure) is connected to the rechargeable battery 17 via the charging circuit 172. The combination of the charging interface 171 and the charging circuit 172 enables the extended battery life of the visual ear pick.
[0047] In this embodiment, as Figure 2 As shown, the charging circuit 172 consists of a TP4054 chip U2 and its peripheral circuitry. In this embodiment, the input of the charging circuit 172 is connected to the charging interface 171, and the output of the charging circuit 172 is connected to an interface J1, which is connected to the rechargeable battery 17. Preferably, the rechargeable battery 17 consists of two 1.5V rechargeable batteries.
[0048] The key design feature of this utility model is that users can load a WeChat mini-program on their mobile terminal to establish a signal connection with the Bluetooth main control module. Through the WeChat mini-program, users can view the image information captured by the camera in real time without downloading a corresponding APP, which greatly improves the user experience. Moreover, through the cooperation of the power button and the microcontroller circuit, one-button power on / off can be achieved, and the microcontroller circuit can wake up the Bluetooth main control module, which greatly reduces the power consumption of the Bluetooth main control module.
[0049] Secondly, the battery life of the visual ear spoon is greatly improved through the combination of rechargeable battery, charging circuit and charging interface.
[0050] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
