Description

[0001] The present invention relates to a portable water purification system and, more particularly, to multifunctional water purification devices that generate renewable energy for charging electronic devices such as smartphones.

[0002] Access to clean drinking water and reliable electricity remains a major challenge in many remote and underdeveloped regions of the world. Conventional water purification devices are designed solely to remove contaminants and pathogens from water to make it safe for human consumption. At the same time, the increasing reliance on mobile electronic devices such as smartphones has led to a growing need for off-grid charging solutions, particularly in situations where conventional power sources are inaccessible—such as during natural disasters, remote expeditions, or in rural areas. While portable power banks and solar chargers are available, they often require separate transport, maintenance, and charging and are not always reliable due to weather or battery degradation.Currently, there is no widely used integrated system that simultaneously purifies water and generates electrical energy to charge electronic devices. This discrepancy between water purification and access to energy highlights a technological gap that this invention aims to fill.

[0003] To solve this problem, the present invention provides a water purification device for charging smartphones.

[0004] The device is designed to simultaneously purify water and generate electrical energy through the kinetic flow of the water, providing a reliable source of clean drinking water and electricity to charge electronic devices such as smartphones, tablets and other low-power devices.

[0005] The device is capable of generating electrical energy through the water flow with the help of an integrated microgenerator and using this energy to charge electronic devices such as smartphones, tablets or other low-power devices.

[0006] The device is capable of purifying water while simultaneously generating electrical energy, allowing users to charge electronic devices such as smartphones, especially in off-grid or emergency situations where access to clean water and electricity is limited.

[0007] In one embodiment, the present invention provides a smartphone charging water purification device. The present invention provides a dual-purpose device that combines water purification and mobile device charging in a single compact unit. The system integrates a water-powered microgenerator capable of generating electrical energy as water flows through the purifier. This energy is used to charge small electronic devices such as smartphones, either directly or via an interposed battery storage module. The water purifier uses standard or advanced filtration methods to remove contaminants and improve water quality, while simultaneously converting hydraulic energy into electrical energy using an integrated turbine generator or similar mechanism.The generated power is either used immediately to charge connected devices or stored in a rechargeable battery built into the device. This multifunctional system addresses the urgent need for drinking water and reliable power sources in remote, off-grid, disaster-affected, or outdoor areas. It offers a cost-effective and practical solution for users without access to electricity, enabling water purification and electronics charging without the need for an external power source. The system is user-friendly, portable, and robust, making it especially valuable for emergency kits, humanitarian aid, outdoor camping, and rural applications. The invention is explained again below.

[0008] The present invention relates to a smartphone-charging water purifier configured to perform the dual functions of water purification and portable device charging, and more particularly, to a water purifier integrated with a power generation system capable of charging electronic devices, such as smartphones, using water flow as the power source. The operation of the smartphone-charging water purifier is controlled by a logical control sequence illustrated in the attached flowchart. The process begins with a power availability check. Once the presence of a power supply (either from a turbine or a battery) is confirmed, the user selects one of three operating modes: (i) water purification only, (ii) smartphone charging only, or (iii) simultaneous operation of both functions.In water purification mode, the system checks for the presence of water and the condition of the filter before beginning the purification process. Once the process is complete and clean water is dispensed, the system indicates success. In charging mode, the system checks whether the battery has enough power to initiate the charging process and, if confirmed, begins charging.

[0009] The system monitors the charging status until the phone is fully charged; after that, the process is marked as successful. If both functions are selected, the system activates them simultaneously and manages power distribution and operational controls for both subsystems. This intelligent control logic ensures safe, efficient, and user-controlled use of the dual-function purifier and charger. The invention provides a compact, portable device that combines water purification and smartphone charging. It includes a water inlet, a microturbine generator that converts flowing water into electricity, and a multi-stage filtration system (sediment, carbon, RO, and / or UV-C) to remove contaminants. The generated power is stored in a rechargeable battery (5,000–10,000 mAh) and provided via USB ports (5–15 watts) for charging electronic devices.An optional smart module enables Bluetooth / Wi-Fi connectivity for monitoring water quality, battery status, and filter life. Designed for off-grid, emergency, and outdoor use, the device offers a self-contained clean water and power solution that uniquely combines two critical utilities into one system.
