[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0027] like Figure 1-5 As shown, the intelligent cloud electronic scale of this application includes components such as a button panel 1, a support frame 2, a circuit board protective shell 3, a scale body shell, and a transparent cover 5. The components work together to ensure that the electronic scale has good moisture and water resistance and stable operation.

[0028] The button panel 1 is located in the operating area on the top of the electronic scale. Its structure mainly consists of several buttons for user operation and data interaction. An elastic rubber pad 12 is fitted to the bottom of the button panel 1, creating a flexible seal to prevent external moisture from seeping in. Furthermore, a ring of waterproof protrusions 13 is designed around the button panel 1 to intercept water droplets or liquids from flowing into gaps, preventing direct contact with internal electronic components. Technically, this component can be injection molded, and the rubber pad and waterproof protrusions 13 can be precisely positioned and fitted using a mold.

[0029] The support frame 2, as the core support component of the entire equipment, provides structural stability and secures other components. Its hollow interior allows the circuit board protective shell 3 and other functional components to be embedded within. Manufactured using methods such as metal stamping or engineering plastic injection molding, it meets the strength requirements of different environments while ensuring sufficient durability and corrosion resistance.

[0030] The circuit board protective shell 3 is placed inside the support frame 2 and tightly connected to the button panel 1, together forming a sealed cavity space. This protective shell is usually made of high-molecular polymer material, which has strong insulation and moisture resistance, thus effectively protecting the internal sensitive circuits from damage in harsh environments. During installation, it can be seamlessly connected to the button panel 1 by screw tightening, snap-fit ​​connection, etc., forming a closed barrier.

[0031] The scale's outer shell completely encloses all the aforementioned components, achieving a clean overall appearance and enhancing external protection. It is typically composed of two or more shell units joined together, secured with screws or adhesive during assembly. To further optimize aesthetics and user experience, surface treatments such as spraying and anodizing can be used to improve tactile feel and gloss.

[0032] The transparent cover 5 is positioned directly above the button panel 1, providing a more intuitive user interface and effectively preventing interference from external objects. It is made of a preferred optical-grade transparent material (such as acrylic sheet or tempered glass), combining high strength and wear resistance with lightweight properties for stable operation over extended periods. In practice, it is securely fastened to the corresponding slot using an embedded design, further enhanced by sealing strips to improve airtightness.

[0033] To address the challenges of moisture and water resistance and enhance durability, this solution incorporates several innovative designs: First, the elastic rubber pad 12 at the bottom of the button panel 1 acts as an additional insulating layer, preventing water vapor transmission. Second, the annular waterproof protrusions 13 around the panel's outer perimeter block most water flow channels, preventing accidental liquid spills from easily breaching the protective barrier and threatening the internal components. Furthermore, the sealing structure, such as the combination of the protective shell and cover, plays a crucial role in minimizing the impact of air humidity on the internal system. These measures collectively constitute a comprehensive protective network, ensuring the long-term reliable operation of this intelligent cloud electronic scale.

[0034] like Figure 2As shown, in one embodiment, load cells 6 are installed at the four corners and the center of the weighing body shell 4 of the intelligent cloud electronic scale of this application. The positional distribution of these load cells 6 ensures that they can accurately sense the pressure signals applied by the object and convert them into corresponding weight data. Specifically, the load cells 6 are located at key load-bearing points at the top of the weighing body shell 4: the four corners provide structural balance to support the entire weighing surface, while the center serves as an additional sensing node to compensate for inaccurate data caused by the object being placed off-center. The load cells 6 themselves are composed of high-precision elastic elements and signal acquisition circuits, possessing stable response capabilities and high sensitivity. In addition, the sensors are electrically connected to the circuit board via built-in wires, and shielding protection measures are adopted to prevent external electromagnetic interference.

[0035] For example, installation can be completed by first fixing each load cell 6 into a pre-drilled groove in the weighing housing 4, where the depth of each groove is precisely designed to fit the sensor size, and then firmly fixing it in the correct position with fasteners or adhesive materials. This not only makes the load cells 6 stable and less prone to loosening, but also avoids the risk of displacement during long-term use.

[0036] like Figure 5 As shown, in one embodiment, the elastic rubber pad 12 of the intelligent cloud electronic scale of this application is composed of multiple layers of microporous elastic material. Specifically, an adhesive is coated between these microporous elastic material layers to achieve a tight and effective connection. The elastic rubber pad 12 is disposed at the bottom of the button panel 1, closely adjacent to the circuit board protective housing 3. This position can effectively isolate external humid gases from damaging the internal components. Since a sealed cavity space is formed between the button panel 1 and the circuit board protective housing 3, this design helps to further improve the overall moisture-proof and waterproof performance of the electronic scale. In addition, this structure not only increases the elasticity of the rubber pad, but also reduces the risk of aging and embrittlement in humid environments. This ensures that the elastic rubber pad 12 can continuously provide reliable cushioning and protection under complex usage conditions, ensuring that users still have a good operating experience and safety factor after long-term use.

[0037] For example, the elasticity and waterproof rating of the rubber pad can be adjusted by selecting microporous elastic materials with different thicknesses and density ratios, and the number of material layers and the amount of adhesive applied can be reasonably determined according to the required performance indicators. To achieve better waterproofing, die casting or molding can be used during production to ensure a tight bond between each material layer, and the overall structural strength and stability can be verified through a rigorous quality inspection process.

[0038] like Figure 5As shown, in one embodiment, the surrounding waterproof protrusion 13 of the intelligent cloud electronic scale of this application is filled with a moisture-absorbing sponge layer 7. Specifically, the surrounding waterproof protrusion 13 is installed at the bottom of the button panel 1 and arranged around its edge to form a closed moisture barrier. The moisture-absorbing sponge layer 7 is embedded in the internal space of the waterproof protrusion 13 and works together with its external protruding surface. This design, through a reasonable structural layout, further reduces the possibility of moisture entering the device.

[0039] The aforementioned features can be achieved in various ways during technical implementation. For example, during the manufacturing process, the moisture-absorbing sponge material is precisely cut and fixed to the space reserved in the surrounding waterproof protrusion 13, ensuring uniform filling without air bubbles. Furthermore, by selecting a moisture-absorbing sponge material with specific pore size and absorption properties, the absorption efficiency of moisture can be improved. Subsequent processing involves applying additional edge sealing to the surface of the surrounding waterproof protrusion 13 to prevent leakage. Simultaneously, this component must fit tightly against the connection between the button panel 1 and the support frame 2 to ensure stability and reliability after assembly.

[0040] like Figure 2 As shown, in one embodiment, a sealing strip 8 is provided between the button panel 1 and the transparent cover 5 of the intelligent cloud electronic scale of this application. The sealing strip 8 is made of silicone material to ensure a tight seal. The sealing strip 8 is positioned at the edge of the button panel 1, closely abutting its mounting area and fitting snugly with the transparent cover 5, thereby effectively isolating it from the influence of external environmental factors. By using silicone material, the sealing strip 8 not only provides the necessary elasticity to fill assembly gaps caused by tolerance accumulation, but also adapts to different operating temperature ranges.

[0041] Specifically, the edge of the button panel 1 has a pre-designed groove to accommodate the sealing strip 8, ensuring that the sealing strip 8 is securely pressed between the two components when the transparent cover 5 is installed above the button panel 1. This design creates a double layer of protection: firstly, the excellent elasticity of the sealing strip 8 fills any tiny gaps; secondly, mechanical assembly force applies pressure to ensure a tight bond between the transparent cover 5 and the button panel 1, further enhancing the device's resistance to harmful external factors such as dust and moisture. For example, during actual assembly, the pre-molded silicone sealing strip 8 can be inserted into the corresponding groove of the button panel 1, then the transparent cover 5 can be aligned and fastened, ensuring that the sealing strip 8 is evenly compressed to achieve a reliable airtight connection.

[0042] like Figure 2As shown, in one embodiment, the weighing sensor 6 of the intelligent cloud electronic scale of this application is provided with a tray 9 on its upper end. This tray 9 is mainly used to support the object being measured, providing a platform for the user to place the object. This platform has a large planar structure and is horizontally mounted on the weighing sensor 6, thereby effectively transmitting the gravity from the object to the weighing sensor 6 and accurately reflecting the weight information. To ensure good mechanical stability and accurate transmission, the tray 9 is typically made of high-strength, corrosion-resistant materials, such as stainless steel or composite fiberboard. Furthermore, the tray 9 and the weighing sensor 6 are fixedly connected by threads or snap-fit ​​methods to prevent displacement and ensure unobstructed force transmission path.

[0043] For example, positioning holes or inserts can be pre-drilled at the bottom of the tray 9 for precise assembly, and then screws can be used to lock the tray 9 to the end plane of the load cell 6. This design not only facilitates disassembly and maintenance, but also meets the needs of size replacement under different weighing tasks, thereby expanding the applicability and flexibility of the equipment.

[0044] like Figure 4 and Figure 5 As shown, in one embodiment, the inner surface of the circuit board protective shell 3 of the intelligent cloud electronic scale of this application is uniformly distributed with desiccant granular bags 10. These bags contain calcium chloride or other high-efficiency chemical desiccant to maintain the humidity within the sealed cavity within a safe range for a long time. By rationally arranging and selecting high-performance desiccant materials, the entire interior of the electronic scale can maintain a stable humidity environment for a long time, ensuring that key components such as circuits and sensors are not affected by moisture, thereby improving service life and stability. In particular, this design not only considers the needs of static humidity control, but also fully considers the requirements for continuous and stable operation in various environments.

[0045] To ensure the circuit board operates under optimal conditions, the desiccant granule bags 10 are carefully positioned so that they are evenly distributed on all four sides of the circuit board protective housing 3, ensuring effective coverage of every corner. These desiccant granule bags 10 are individually sealed and filled with highly absorbent, long-lasting calcium chloride or similar high-efficiency desiccant, and are fixed to the inner surface of the circuit board protective housing 3 to prevent displacement due to vibration or handling. This method not only achieves comprehensive moisture protection but also does not affect the installation and connection structure of other components, ensuring a compact and rational overall layout of the electronic scale.

[0046] For example, the specific technical means to achieve the above features is as follows: First, select a desiccant bag material that meets the specifications and has good heat resistance for packaging; fill the bag with desiccant according to the set ratio and seal it firmly; then, use adhesive, clips, or double-sided tape to tightly fix it to the appropriate areas on the four sides of the circuit board protective shell 3. Ensure that the spacing between each bag is consistent to achieve a balanced distribution and avoid local differences in moisture absorption capacity caused by uneven installation.

[0047] like Figure 3 As shown, in one embodiment, the circuit board protective shell 3 of the intelligent cloud electronic scale of this application is firmly connected to the support frame 2 through specific technical measures, and this connection adopts a waterproof adhesive method. Specifically, the circuit board protective shell 3 is arranged inside the support frame 2, adjacent to the bottom area of ​​the button panel 1, forming a well-sealed internal cavity environment. This cavity is used to accommodate key electronic components and isolate them from the influence of external moisture. To ensure that the bonding interface can withstand the test of complex usage environments, a specially developed waterproof polyurethane adhesive is used as a fixing method. In addition, this installation method not only ensures the stability of the mechanical structure, but also enables the electronic scale to adapt to various humidity conditions.

[0048] For example, a waterproof polyurethane adhesive can be evenly applied to the edges of the circuit board protective shell 3 and the corresponding contact areas of the support frame 2 using a precision dispensing process. Subsequently, pressure is applied during assembly to ensure full adhesion, and after a certain period of curing, the two components are ultimately formed into an inseparable integral structure, guaranteeing long-term stability and sealing.

[0049] like Figure 1 and Figure 2 As shown, in one embodiment, the transparent cover 5 of the intelligent cloud electronic scale of this application is disposed above the button panel 1 to protect the operating area and improve the overall protective performance of the device. The transparent cover 5 has specially designed reinforcing components at its four corners. These components are installed in positions corresponding to the area around the button panel 1, ensuring a secure mechanical connection between the two. Specifically, the reinforcing components are reinforcing studs 11, made of high-strength material, with standard threads on the outside for easy locking with nuts.

[0050] For example, this structure can be connected by pre-drilling screw holes at the four corners of the transparent cover 5, and providing matching positioning holes in the corresponding area of ​​the button panel 1. After the studs are inserted, tightening the outer nuts balances the forces between the components, forming a stable overall structure. At the same time, this connection method can reduce the impact of external vibrations on the internal circuitry of the smart cloud electronic scale, enhancing the reliability of the equipment during long-term use.

[0051] like Figure 4 and Figure 5As shown, in one embodiment, the wraparound waterproof protrusion 13 of the intelligent cloud electronic scale of this application is made of fluorosilicone rubber. The wraparound waterproof protrusion 13 is tightly fitted to the edge of the button panel 1 and is fixedly connected to the button panel 1 through a specific process. This material has good physical and mechanical properties and elastic recovery, which can ensure its shape stability during long-term use. In addition, fluorosilicone rubber also exhibits excellent resistance to oily environments and aging resistance, thus adapting to complex application scenarios.

[0052] The specific installation method of the wraparound waterproof protrusion 13 is as follows: it completely wraps around the outer contour of the button panel 1, playing a crucial sealing role during the installation of the button panel 1 and the transparent cover 5. Specifically, the fluorosilicone rubber component is precisely molded using techniques such as injection molding, and then firmly bonded to the button panel 1 using adhesives or other fixing methods, ensuring that there are no gaps or loosening after assembly. For example, an adhesive layer can be applied to position and fix the wraparound waterproof protrusion 13, thereby constructing an effective liquid barrier. This method not only improves the overall structural integration but also enhances the environmental adaptability of the smart cloud electronic scale.

[0053] In actual operation, when using this device, the user first sets up and starts the operation via buttons on the button panel 1. At this time, the elastic rubber pad 12 at the bottom of the button panel 1 ensures that humid air will not be conducted in from below. The user can place the item to be weighed on the scale body, and the device begins to automatically identify and weigh it. The weighing data is processed and displayed on the button panel 1, and can interact with external devices or the cloud. To prevent water droplets from entering the interior, a ring of waterproof protrusions 13 is designed above the button panel 1, effectively preventing moisture from penetrating into the cavity space. Throughout the process, the support frame 2 provides stable structural support for all components, while the circuit board protective shell 3 is tightly adjacent to the button panel 1, forming a sealed internal environment to ensure the safety of electronic components. The transparent cover 5 is embedded above the button panel 1, making the operating area clearly visible and further preventing foreign object intrusion, ensuring normal operation of the device. Finally, the entire device is encased in the scale body shell, forming a complete and well-protected appearance, ensuring that the smart cloud electronic scale works stably and reliably in various environments.
