Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0043] like Figure 1 As shown, a weighing system integrated onto a drying rack is ingeniously designed and uniquely functional, bringing great convenience to daily life. The system mainly consists of several key components: a long, narrow drying rack 1, a thin-film pressure sensor 2, and a control circuit.

[0044] The drying rod 1 serves as the basic support structure of the entire system, comprising the rod body 11 and the hanging part 12 located on the upper side of the rod body 11. The rod body 11 is made of high-strength and lightweight materials, such as aluminum alloy, ensuring that the drying rod has sufficient load-bearing capacity to support the weight of clothes for daily drying, while also making the entire drying rod lightweight and easy to install. The hanging part 12 has multiple hanging positions 121, which are evenly distributed and their spacing is carefully designed to meet the hanging needs of hangers of different sizes while ensuring the uniform force on the drying rod when hanging clothes. The hanging positions 121 are recessed areas on the drying rod 1. This design allows the hooks of the hangers to be securely hung in the recessed areas, effectively preventing the hangers from sliding or falling off the drying rod, greatly improving the stability of hanging clothes.

[0045] like Figures 3-5As shown, the thin-film pressure sensor 2 is located on the rod body 11 below the hanging part 12, extending along the length of the rod body 11. The hanging part 12 bears the weight of the thin-film pressure sensor 2. This structural design allows the pressure generated when clothes are hung on the hanging position 121 of the hanging part 12 to be directly transmitted to the thin-film pressure sensor 2. The thin-film pressure sensor 2 includes a long strip of conductive base 21 and multiple sensing units 22. The conductive base 21 is made of a material with good conductivity and flexibility, such as a layer of conductive metal plated on a polyethylene terephthalate (PET) substrate. This material combination ensures conductivity while adapting to the shape of the drying rod. Multiple sensing units 22 are distributed along the length of the conductive base 21, and each sensing unit 22 corresponds one-to-one with a hanging position 121. Each sensing unit 22 has a highly sensitive pressure sensing capability. When clothes are hung on the corresponding hanging position 121, the sensing unit 22 can accurately detect the pressure change caused by the weight of the clothes and convert this pressure change into an electrical signal. The conductive baseband 21 is connected to the control circuit. Through the conductive baseband 21, the electrical signals generated by each sensing unit 22 can be smoothly transmitted to the control circuit for subsequent processing.

[0046] Specifically, the conductive baseband 21 is divided into two sections, with the battery compartment 113 located in the middle of the drying rod. The two interfaces 211 of the conductive baseband 21 are electrically connected to the PCB board 115 inside the battery compartment.

[0047] A long strip of soft pad 3 is provided between the hanging part 12 and the thin-film pressure sensor 2. The soft pad 3 is made of a soft and elastic material, such as silicone, and its function is to buffer the pressure transmitted from the hanging part 12 to the thin-film pressure sensor 2, avoiding damage to the sensor due to excessive pressure concentration or instantaneous impact, thereby effectively extending the service life of the thin-film pressure sensor 2. The lower side of the rod body 11 is provided with multiple positioning posts 111 corresponding one-to-one with the hanging positions 121; the soft pad 3 is provided with positioning sleeves 31 corresponding one-to-one with the positioning posts 111. The cooperation of the positioning posts 111 and the positioning sleeves 31 enables the soft pad 3 to be quickly and accurately positioned during installation, ensuring the positional stability of the soft pad 3 on the rod body 11, and also ensuring that the pressure on the soft pad 3 can be evenly transmitted to each sensing unit 22 of the thin-film pressure sensor 2. Moreover, the one-to-one correspondence between the positioning sleeves 31 and the sensing units 22 further ensures the accuracy of pressure transmission.

[0048] The upper end face of the rod body 11 has a groove 13 distributed along the length of the rod 1. The thin-film pressure sensor 2, the soft pad 3, and the positioning post 111 are located in the groove 13. The design of the groove 13 not only provides a safe and stable installation space for these components, but also provides them with a certain degree of protection, preventing them from being hit and damaged by external forces. At the same time, this embedded design makes the overall appearance of the drying rod more concise and beautiful, and reduces the potential safety hazards caused by protruding components.

[0049] like Figures 6-7 As shown, the main body 11 of the pole has a battery compartment 113, which contains a battery 114 and a PCB board 115 with control circuitry. The battery 114 provides stable power to the entire weighing system, ensuring continuous normal operation. The control circuitry is integrated on the PCB board 115. It receives electrical signals from the thin-film pressure sensor 2, analyzes, processes, and converts these signals, and finally presents the processed signals to the user in an intuitive way. For example, it can display the weight information of the clothes hanging on each hanging position 121 through a connected display screen, making it convenient for users to understand the weight of the clothes and arrange the drying layout reasonably.

[0050] like Figures 3-5 As shown, in the development of modern smart homes, a highly efficient and intelligent clothing dryness recognition system has emerged, bringing great convenience and technological experience to users' daily lives. The system mainly consists of a drying rod 1, a clothes drying unit 4, a processing module, and a display screen 6. These components work together to accurately determine the dryness of the clothing.

[0051] The drying rod 1, as the fundamental load-bearing component of the entire system, is ingeniously designed. A weighing system is cleverly integrated into the drying rod 1, employing thin-film pressure sensors 2. These thin-film pressure sensors 2 are evenly and precisely distributed below each hanging position 121 on the drying rod. The working principle of the thin-film pressure sensors 2 is based on the piezoresistive effect. When clothes are hung on the hanging position 121, the weight of the clothes exerts pressure on the sensor, causing a change in the resistance value inside the sensor, thereby generating an electrical signal output proportional to the pressure magnitude. Through this principle, the thin-film pressure sensors 2 can accurately measure the weight of the clothes on each hanging position, providing crucial weight data support for subsequent judgment of the dryness of the clothes. Moreover, due to their uniform distribution, the accuracy and consistency of the measurement are guaranteed regardless of where the clothes are hung on the drying rod, greatly improving the reliability of the weighing system. Figure 2 As shown, the display screen can be the display screen on a wall-mounted switch or the display screen of a mobile terminal.

[0052] The clothes drying rack main unit 4 plays a crucial role in the entire system for acquiring visual information. The main unit 4 is equipped with a high-definition camera 41, possessing superior image capture capabilities. Its high-definition nature ensures clear and sharp images of the clothing, accurately capturing subtle textures, colors, and wrinkles, laying a solid foundation for accurate clothing type identification. More importantly, the camera 41's shooting angle is flexibly adjustable. Through a motor-driven mechanical structure, users can manually or intelligently adjust the camera's tilt and horizontal rotation angles according to their needs. This ensures that regardless of how the clothes are hung on the drying rack, the camera 41 comprehensively captures images of the clothing at each hanging position, ensuring no important information is missed and greatly improving the accuracy and comprehensiveness of clothing type identification.

[0053] The processing module, acting as the "brain" of the entire system, plays a crucial role. It is closely connected to the weighing system and camera 41, receiving real-time weight data from the weighing system and image data of the clothing captured by camera 41. Upon receiving the data, the processing module first processes the clothing images using an advanced image recognition algorithm. This algorithm, trained on a large amount of sample data, can accurately identify the type of clothing, such as cotton, synthetic fiber, and wool. Different types of clothing exhibit different weight change patterns during the drying process due to their varying material properties. The processing module combines this clothing type information with the weight data provided by the weighing system, using a pre-set mathematical model and algorithm to determine the degree of dryness for each garment. For example, cotton clothing experiences relatively uniform moisture evaporation during drying, and its weight gradually and steadily decreases over time; while the drying speed and weight change pattern of synthetic fiber clothing differ from that of cotton clothing. Through the analysis and processing of this complex data, the processing module can accurately determine the drying stage of each garment.

[0054] Display screen 6, as an important interface for system-user interaction, is located on the control panel of the clothes drying machine main unit 4.

[0055] This design fully considers user convenience. Users can easily obtain information about the dryness of their clothes without having to search for a specific location while operating the clothes dryer. The display screen typically uses liquid crystal display (LCD) or organic light-emitting diode (OLED) technology, offering high brightness, high contrast, and clear display effects. It can clearly display the dryness level of each garment in an intuitive way, such as using different colored progress bars or percentage numbers, allowing users to understand the situation at a glance.

[0056] Further analysis of the system's internal structure reveals the following key modules:

[0057] The data acquisition module consists of a weighing system composed of a thin-film pressure sensor and a camera 41. The weighing system continuously and stably collects clothing weight data through the piezoresistive effect of the thin-film pressure sensor and converts it into an electrical signal, which is then transmitted to the processing module. The camera 41 captures images of the clothing through its optical lens, converts the light signal into a digital signal, and also transmits it to the processing module. These two components work together to provide the system with a rich and accurate data source.

[0058] Data Processing Module: This module is the core computing unit of the system. It performs complex and precise processing on the received data. In image recognition, advanced algorithms such as Convolutional Neural Networks (CNNs) are used to extract features and classify clothing images, accurately identifying clothing types. When combining weight data to determine the degree of dryness, algorithms such as Dynamic Time Warping (DTW) are used to compare the standard weight change curves of different types of clothing during the drying process with real-time measured weight data, thereby accurately determining the degree of dryness of the clothing.

[0059] Storage Module: The storage module plays a crucial role in data storage and management within the system. It stores a large amount of historical data, including information such as the type, weight, dryness level, and corresponding drying time of past garments. This historical data provides valuable reference for system optimization and improvement. Simultaneously, the storage module also stores preset model and algorithm parameters, such as training parameters for the garment type recognition model and mathematical model parameters for determining dryness level, ensuring the system operates stably and accurately under different environments and conditions.

[0060] Display Module: The display module is responsible for presenting the clothing dryness information obtained by the processing module to the user in an intuitive and easy-to-understand way. In addition to displaying the information on the display screen 6 on the control panel of the clothes drying rack main unit 4, some high-end systems also support connection with mobile terminals such as mobile phones, displaying clothing dryness information on the mobile phone screen through a dedicated application (APP), further facilitating users to check the drying status of their clothes anytime, anywhere.
