[0002] Handheld Water Purification Device

[0003] Field of Invention

[0004] The present novel invention falls within the domain of water purification technologies, specifically focusing on handheld and portable - pocket sized device that is designed to provide safe, clean, and bacteria free drinking water on-the-go using ultraviolet (UV) light and silver electrodes.

[0005] Background of Invention

[0006] Access to clean drinking water is a fundamental human right and a critical determinant of public health and wellbeing. However, in many parts of the world, obtaining safe and potable water remains a significant challenge. This is especially true in rural or remote areas, as well as in developing nations, where water sources may be contaminated with harmful microorganisms and access to advanced water treatment systems is limited. Contaminants such as E. coli, V. cholerae, S. typhi, and Pseudomonas cause various illnesses, including diarrhea, dysentery, urinary tract infections, cholera, and typhoid.

[0007] Conventional water purification methods, such as boiling or chemical treatment, can be timeconsuming, inefficient, or inaccessible to those with limited resources. This often leads to the spread of waterborne diseases, causing illness, mortality, and significant societal impacts. Traditional water purification methods often fall short in terms of portability, and accessibility, particularly for individuals on the move or those residing in remote locations.

[0008] The current reliance on packaged drinking water, typically supplied in plastic bottles, presents environmental concerns due to plastic degradation and the release of microplastics into the gut, posing long-term health risks. There is a pressing need for an eco-friendly, effective, and portable water purification solution that reduces the dependence on single-use plastic bottles. An invention disclosed in patent application number KR20090003754U discloses Install batteries, especially button-type power supplies, silver electrodes, etc., inside the lid of the bottle with the capacity for one-time drinking, and use ordinary drinking water such as water, weak, and mineral water. Practical silver maker and portable drinking water sterilizer with simple structure for producing silver water

[0009] An invention disclosed in patent application number CN210657160U discloses a portable disinfectant generator, which comprises a battery, an anode piece electrically connected with the anode of the battery and a cathode piece electrically connected with the cathode of the battery, the anode piece is a silver piece or a silver alloy piece, and a waterproof sealing cavity used for coating the battery is arranged outside the battery. The disinfectant generator provided by the utility model is put into water; the silver ion disinfectant can be formed by releasing silver ions in water through electrolytic reaction, the disinfectant can be prepared according to needs, the problems of waste, pollution and storage safety of the disinfectant can be effectively solved, and meanwhile due to the fact that an electrolytic bath body and other large parts do not need to be configured, the portable water purifier is convenient to carry when a user goes out and wide in application range.

[0010] Water infused with silver ions, often referred to as "silver water" or "colloidal silver," has been a subject of interest for its potential health benefits and antimicrobial properties. Here are some of the purported benefits of water with silver ions: Antimicrobial Action, Improved Water Quality, Gut Health, Immune Support, Wound Healing, Anti-Inflammatory Effects, Skin Care, and Longevity and Freshness.

[0011] It is important to note that while silver ions in water may offer potential benefits, excessive silver ions in water can pose health and environmental risks. Short-term Exposure of excessive silver can cause irritation of the skin, eyes, and throat and Long-term Exposure May lead to argyria, a condition where the skin turns a bluish-gray color due to silver accumulation in the body. Other potential effects include liver and kidney damage, respiratory and intestinal irritation, and neurological issues.

[0012] The present novel invention is primarily based on the emission of alternating and regulated current, which plays a crucial role in the electrolysis process. This process involves two silver rods, designated as the anode and cathode, immersed in the water. When the current flows through these rods, it induces the release of silver ions into the water. These ions possess strong microbicidal properties, effectively targeting and neutralizing a wide range of harmful microorganisms including various bacteria. This ensures a high level of disinfection, making the water safe for consumption.

[0013] Moreover, the system is enhanced with a UV LED light, which provides an additional layer of protection. The UV light targets and deactivates microorganisms by disrupting their DNA, preventing them from reproducing and causing harm. This dual-action approach— combining the microbicidal properties of silver ions with the sterilizing power of UV light— significantly boosts the overall effectiveness of the purification process and shows significant synergistic effect.

[0014] The UV LED light emits a distinctive blue color during operation, serving as a visual indicator that the purification process is active. This feature not only provides a clear indication of the system's status but also offers a level of assurance to the user that the water is being treated. Once the purification cycle is complete, the UV light automatically turns off. This automatic shutoff function is crucial as it signals that the water has been purified and is now safe for consumption, preventing any premature use of potentially untreated water.

[0015] In addition to these core features, the system is designed with user safety and convenience in mind. The use of regulated current ensures that the silver ion concentration remains within safe and effective limits, preventing any potential toxicity from excessive silver ion release. The combination of electrolysis and UV sterilization provides a comprehensive purification solution, addressing a broad spectrum of contaminants.

[0016] This innovative approach not only enhances water safety but also promotes user confidence in the purification process. The integration of visual indicators and automatic control simplifies the user experience, making it easier to ensure that the water being consumed is thoroughly purified and safe. Overall, the present novel system represents a significant advancement in water purification technology, combining multiple disinfection methods to deliver reliable and effective results.

[0027] Summary

[0028] The present novel invention stands out for its innovative approach to current regulation and microbial neutralization, revolutionizing the way we purify water. At the core of the present novel invention is a meticulously designed electric circuit that emits a precisely controlled and alternating current, setting the stage for a dynamic electrolysis process. The two pure silver electrodes, strategically positioned within the device, serve as the anode and cathode. Through the regulated emission of alternating current, an electrolysis process unfolds, resulting in the generation of silver ions with remarkable microbicidal properties. This controlled current emission is the core of the invention, as it harnesses the power of silver ions to effectively target and neutralize a diverse range of microorganisms, including bacteria, and pathogens. This dynamic process allows for a more comprehensive purification effect, addressing a broader spectrum of contaminants. Furthermore, the incorporation of ultraviolet (UV) LED light adds microbial neutralization. The UV light, with its well-known germicidal properties, targets any remaining microorganisms that may have evaded the initial silver ion treatment. This dual-action approach ensures that the treated water undergoes a thorough purification process, enhancing its safety and portability. The UV LED light also introduces an element of user-friendly innovation. The blue light emitted during the purification process serves as a visual indicator, providing real-time feedback to the user. The use of color acts as a built-in timer, automatically turning off the device when the purification is complete, thus ensuring safe consumption. This combination of technologies not only enhances the purification process but also simplifies the user experience, eliminating the need for complex monitoring or guesswork. The automatic shut-off feature guarantees that users consume only purified water, instilling confidence in the safety and quality of their drinking water.
