[0018] An embodiment of this application provides an atomizer control connection cable.

[0019] The embodiments of this application aim to solve the problems of poor compatibility and inflexible control in existing wired atomizing products. Specifically, it aims to address the issue of poor compatibility of the liquid cup caused by the atomizing drive circuit 100 being built into the wired interface device, and the problem of the wired drive board relying on physical buttons and being unable to be controlled through the wired interface device. The embodiments of this application provide a customizable atomizer control cable that integrates its own drive circuit, enables data transmission, allows control of the atomization function via host computer software, and is compatible with multiple devices.

[0020] This connecting cable is suitable for various wired atomizing products, is compatible with a variety of devices, and can be widely used in medical atomization, home atomization and other scenarios to achieve flexible control of the atomization function.

[0021] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0022] Reference Figures 1 to 4The atomizer control connection cable includes: cable body, main control chip 200, interface conversion chip 300 and atomization drive circuit 100.

[0023] Reference Figure 1 The two ends of the cable are a first port 410 for connecting to the medicine cup and a second port 420 for connecting to the nebulizer.

[0024] One end of the interface conversion chip 300 is connected to the second port 420, and the other end of the interface conversion chip 300 is connected to the main control chip 200. The interface conversion chip 300 is used to convert control commands from protocol signals to serial port signals.

[0025] The main control chip 200 is connected to the atomization drive circuit 100. The main control chip 200 is used to output PWM signals to control the atomization drive circuit 100 according to the control instructions.

[0026] The atomization driving circuit 100 is disposed in the wire body. The two ends of the atomization driving circuit 100 are connected to the first port 410 and the second port 420 respectively through wires. The atomization driving circuit 100 includes a driving module, a frequency sweeping module and a power adjustment module.

[0027] The main control chip 200, interface conversion chip 300, and atomization drive circuit 100 are integrated inside the cable. A miniaturized and integrated design is adopted, using high-performance chips and electronic components to ensure stable atomization drive function within a small space. The drive circuit uses a dedicated atomization drive chip as the core component, combined with capacitors, resistors, and other peripheral components to form a stable circuit. The circuit design considers miniaturization, integrating it in an appropriate location within the cable and providing insulation and protection to ensure it is not affected by external environmental interference during use.

[0028] The cable features a dedicated data transmission core inside, employing standard communication protocols (such as USB) to enable bidirectional data transmission with the host computer and the interface device. Utilizing the USB interface protocol, it offers strong anti-interference capabilities.

[0029] When using the USB communication protocol, the second port 420 uses a USB port.

[0030] The data transmission cable core is interference-resistant, and the cable body is wrapped with an interference-resistant shielding layer, ensuring the stability and accuracy of data transmission. It accurately transmits control commands from the host computer to the drive circuit of the connecting cable, and also feeds back relevant parameters during the atomization process (such as atomization volume and operating status) to the host computer. The data transmission cable core uses shielded twisted-pair cable to reduce the impact of external electromagnetic interference on data transmission. Inside the connecting cable, the data transmission cable core connects to the communication interface of the drive circuit, realizing communication with the host computer through a corresponding interface circuit. The interface circuit supports plug-and-play functionality, facilitating quick connection and use by users.

[0031] The nebulizer control cable connects the medicine cup and the nebulizer device. The first port 410 connects to the medicine cup, and the second port 420 connects to the nebulizer device. The cable converts the USB protocol signal into a serial port signal through the interface conversion chip 300 to communicate with the main control chip 200. The main control chip 200 receives the control commands through the serial port and then controls the output of the nebulizer drive circuit 100 via PWM.

[0032] To address the following issues: Some atomizing products have driver boards at their cable ends, but these boards require physical buttons for operation. In this case, the cable interface device can only provide power and cannot control the atomizing driver board directly. This control method is inflexible, requiring users to manually press physical buttons, which is cumbersome and makes it difficult to quickly and conveniently control the atomization function in certain scenarios, such as when the user is far from the device. The host computer atomizing device has accompanying host computer software with an intuitive interface. Users can set various atomization parameters, such as atomization rate and atomization time, and send control commands to the cable. Upon receiving the control commands from the host computer, the cable's driver circuit adjusts the atomization drive parameters accordingly, achieving precise control of the atomization function. Simultaneously, the driver circuit feeds back the real-time atomization status to the host computer via the data transmission cable, allowing users to monitor the atomization process in real time. The host computer atomizing device's software interface includes parameter setting areas, status display areas, and control buttons. After the user enters the desired atomization parameters in the parameter setting area and clicks the control button, the software will generate corresponding control commands and send them to the drive circuit of the connecting cable via the data transmission cable. Simultaneously, the software receives data feedback from the drive circuit in real time and displays it in the status display area.

The other ends of the second and fourth voltage divider resistors are grounded. The other end of the first voltage divider resistor is set as the first sampling point, and the other end of the third voltage divider resistor is set as the second sampling point.

[0040] Atomization frequency sweep function: When started, the main control chip 200 outputs a PWM signal within a certain frequency range, gradually increasing the frequency between 100K and 150K, with the frequency output gradually increasing in 1K increments; the frequency point with the largest current is detected through the DIS_A terminal, which is the optimal frequency for the medicine cup, and then the determined optimal frequency is fixedly output to the medicine cup.

[0041] Atomization power adjustment function: By sampling resistor R13, the two AD channels (AD1 and AD2) are used to calculate the working power of the medicine cup during operation, and the output PWM duty cycle is dynamically adjusted to adjust the output power.

[0042] Different liquid medicine cups are equipped with different driving frequencies. The optimal frequency for the liquid medicine cup can be determined by a frequency sweep module, and the operating power of the liquid medicine cup can be calculated by a power adjustment module using a sampling resistor and two-channel AD converters. The atomization drive circuit 100 can provide corresponding drive signals and power outputs according to the needs of different types of liquid medicine cups, so that the liquid medicine cup does not need to rely on the drive circuit at the wire interface device end, and can work normally through this connection cable alone, which greatly improves the compatibility of the liquid medicine cup with different devices.

Controlling the nebulization function via host computer software eliminates the reliance on physical buttons, enabling users to precisely control the nebulization process remotely or through convenient software operation. This makes operation more convenient and efficient, enhancing the user experience. The data transmission function allows the host computer software to receive various parameters during the nebulization process in real time, allowing users to clearly understand the nebulization's working status and easily adjust parameters to ensure the nebulization effect meets expectations.
