Description

Technical Field

[0001] This utility model relates to the field of disinfection and sterilization equipment technology, specifically to a solar-powered ultraviolet sterilization box. This device can sterilize items in outdoor environments without a stable power supply, and is suitable for scenarios such as field operations, camping, and emergency rescue. It can process various items that need to be disinfected, such as medical devices, tableware, and outdoor tools, and also has a lighting function. Background Technology

[0002] In the field of disinfection and sterilization, ultraviolet (UV) sterilization is widely used due to its high efficiency and lack of chemical residues. However, existing UV sterilization equipment still has significant limitations. Most current equipment relies solely on mains power, making it unsuitable for use in scenarios without stable power supply, such as outdoor camping, field exploration, and disaster relief, severely restricting its application. While some portable UV sterilization devices are battery-powered, their limited battery capacity results in short runtimes, requiring frequent charging or battery replacements, making it difficult to meet long-term, continuous disinfection needs. Furthermore, these devices often have a monolithic structure without proper internal partitioning, with batteries, wires, and sterilization components mixed together, which not only easily leads to circuit interference affecting equipment stability but also increases maintenance difficulty. In addition, traditional equipment often uses ordinary translucent materials for the casing, which can easily cause UV leakage, posing a safety hazard. Additionally, some devices are too bulky, making them inconvenient to carry.

[0003] In summary, existing equipment cannot simultaneously meet the three core requirements of "no external power supply", "compact and safe structure" and "long-lasting battery life", and there is an urgent need for an ultraviolet sterilization device that can solve the above problems. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a solar-powered ultraviolet sterilization box that overcomes the limitations of existing ultraviolet sterilization equipment, such as reliance on mains power, poor portability, and insufficient safety protection. The box operates without an external power source by utilizing solar power, and its optimized internal structure enhances safety and portability, meeting the disinfection and lighting needs of outdoor environments.

[0005] The solar-powered ultraviolet sterilization box of this utility model includes a box body, a solar power supply module, an ultraviolet sterilization module, and a lighting module. The specific structure and connection relationship of each module are as follows: The enclosure is constructed with a rectangular frame made of eight profiles. The top plate, bottom plate, left side plate, right side plate, back plate, door frame and door are fixed inside the frame by riveting to form a closed structure. The interior of the enclosure is divided into two independent spaces: a sterilization chamber and a placement chamber. The sterilization chamber is used to place items to be sterilized, and the placement chamber is used to install power supply-related components.

[0006] As a further preferred embodiment, the inner side panel of the box is connected to the top and bottom panels by riveting, the clamping plate is connected to the inner side panel by riveting, and the door frame is connected to the door by riveting.

[0007] As a further preferred embodiment, the door is hinged to the door frame via hinges, and a door handle is installed on the door frame and fixed to the door frame with screws.

[0008] As a further preferred option, the enclosure is made of opaque material to prevent ultraviolet light leakage; through holes are provided on the back panel to ensure air circulation inside and outside the enclosure and to prevent a humid environment from affecting the lifespan of the components.

[0009] The core components of the solar power module include a solar panel, a solar panel mounting bracket, a controller, a battery, and a clamping plate. The solar panel mounting bracket is screwed to the top plate, and the solar panel is fixed to the bracket, allowing for full sunlight absorption. A clamping plate is installed inside the compartment, connected to the left side panel and the top plate by riveting, dividing the compartment into upper and lower layers. The lower layer houses the controller and battery, while the upper layer accommodates the connecting wires, achieving physical separation between the power supply components and the wiring. As a further preferred embodiment, the solar panel is connected to the controller via wires passing through through holes in the back plate, and the controller is connected to the battery via wires passing through through holes in the clamping plate, forming a complete power supply chain of "solar energy absorption - electrical energy conversion - energy storage".

[0010] As a further preferred embodiment, the top plate is fixed to the profile with screws, and the clamping plate is connected to the left side plate and the top plate by riveting.

[0011] As a further preferred option, the solar power module has an automatic switching function. When there is sufficient sunlight, the electricity generated by the solar panel directly powers the equipment and charges the battery at the same time. When there is insufficient sunlight, the controller automatically switches to battery power to ensure continuous operation of the equipment.

[0012] The ultraviolet sterilization module consists of an ultraviolet lamp and an ultraviolet lamp bracket. The ultraviolet lamp bracket is fixed to the back panel of the sterilization chamber with glue, and the ultraviolet lamp is installed on the ultraviolet lamp bracket to ensure that the ultraviolet light can evenly cover the inside of the sterilization chamber. The ultraviolet lamp is connected to the controller through the through hole of the middle partition with wires. A switch is embedded in the right side panel and connected in series with the ultraviolet lamp to control the start and stop of the ultraviolet lamp.

[0013] The lighting module includes two lights and corresponding switches; one light is fixed to the right side panel of the sterilization chamber by bolts and nuts for internal lighting inside the sterilization chamber; the other light is fixed to the door frame in the same way for outdoor ambient lighting; a switch is embedded in the left side panel, and the switch is connected in series with the two lights to achieve independent control; the bolts of the lights are hollow, and the wires pass through the hollow part of the bolts to connect to the battery to avoid exposed wiring.

[0014] Compared with the prior art, the present invention has at least the following significant advantages: First, this utility model adopts a power supply-free approach: it achieves self-sufficiency in electricity through a solar power module, eliminating the need to connect to the mains power supply. It can operate stably in various outdoor power-free scenarios, solving the power supply limitations of traditional equipment.

[0015] Secondly, the structure of this utility model is safe and compact: the internal compartments of the box are clearly defined, and the clamps separate the power supply components from the wires to avoid line interference; the opaque box prevents ultraviolet rays from leaking out, and the hollow bolts hide the wires, improving safety; the overall frame structure is small in size and easy to carry.

[0016] Third, this utility model has diverse and practical functions: it integrates ultraviolet sterilization and lighting functions, which can simultaneously meet the needs of disinfection and outdoor lighting, and is especially suitable for emergency rescue, field operations and other scenarios, making it highly practical.

[0017] Finally, this utility model ensures long-term and stable operation: the controller enables automatic switching between solar power and battery power, and the battery can store electrical energy, ensuring that the equipment can still work normally on cloudy days or at night, thus improving its endurance.
