  • the invention is also related to a kind of water disinfection device which eliminates harmful microorganisms in water by ultraviolet beam and makes the water drinkable.
  • Device has adequate size to allow military personnel can carry it in their backpacks and health service personnel providing mobilized health services, including those working in ambulances, can keep nearby. Available Technique
  • Water is one of the essential substances for the life of living things. More than 70% of the earth is covered with water. About 70% of human body is water. Substance exchange (assimilation, metabolism, secretion and excretion), observed as a characteristic feature in tissues, organs and systems, starting from the cell, which is the basic unit of living things, occurs in a liquid environment, which is essentially the water. Therefore, water is an indispensable requirement for living creatures. Water is social and economic requirement for a healthy (hygienic) life, as well as a physiological need for human. Physiological water need of an adult is 2-2.5 I per day. About 600 cm3 of this is taken with solid foods.
  • Water is made of molecules. Each water molecule is made up of two hydrogen and one oxygen atom. It is an odorless, tasteless, colorless transparent liquid. Ideally, drinking water should contain 0 Escherichia coli per 100 cc and should have no taste, odor, turbidity, residue, or microbes. The water is the most important determinant of the relationship between human and nature, as well as being the basic substance for the life of living things. For this reason, microbiological sterilization of consumption and use water and increasing the water quality are of great importance for human health.
  • UV water purification with mercury lamp In this treatment system, microorganisms in the water are destroyed by UV rays.
  • Microorganisms are destroyed by means of UV LEDs using electrical energy generated by solar panels.
  • UV-C 200-280 nm wavelength
  • Batteries can also be used in all treatment methods other than chemical treatment and purification with sunlight.
  • the treatment system No. 1 (chemical treatment) we mentioned above is a completely different water treatment approach.
  • Water purification system No.2 is an ultraviolet purifier, but the light source is different from others and our invention.
  • Treatment systems No. 3, 4, and 6 in the current technique are similar to our invention in terms of light source but differs in terms of energy source and method of obtaining energy.
  • System No. 5 is completely different from our invention in terms of both light and energy source.
  • This invention relates to a water container with a self-powered sterilization device using a UV LED.
  • the support member in the form of a lid with one end open and one end of the support member Electricity is generated as the magnetic force changes due to the magnetic force being changed by the support plate that forms a space inside while blocking the wall, the magnet part installed in the inner space of the support member, and the coil is installed in several rows along the inner circumferential surface of the support member.
  • the sterilization device is connected to the support plate at one end by emitting light so that the electricity generated from the coil part and the coil part are transmitted to the UV LED to emit ultraviolet rays, and the sterilization device is located in the inner space in the shape of a tube with both ends open.
  • the other end is coupled to one end of the support member and consists of a body containing water, and a stopper that is coupled to one end of the body to prevent the water contained in the body from being discharged to the outside, and the user grabs and shakes the body. Electricity is generated in the coil part as the magnetic force moves between the coil parts by the change, and the electricity generated in the coil part is transmitted to the UV LED of the sterilization device to sterilize the water contained in the body. It is characterized by emitting ultraviolet rays.
  • piezoelectric crystals / ceramics are not used in above invention. It contains expensive and bulky materials such as too many circuit elements, magnets and coils. Since it contains too many circuit elements, it is very possible to deteriorate. It is very costly to manufacture. In case of malfunction, its repair requires mastery, and even is not possible in some situations.
  • the number of windings can be increased to increase the energy to be produced, which will then increase the size considerably, and if used to generate a similar amount of energy as our invention, it must be manufactured in considerably larger sizes than our invention.
  • thickness of the copper in the winding will be determined according to the energy (current) range to be produced. Therefore, if the user shakes too fast copper wires may burn and no additional apparatus is mentioned in the application to prevent this situation.
  • the unit that cleans water is completely within the water. It is mentioned that it has a protection, but in case of any breakage, it directly may pose danger to person who drinks water or cause breakdown in electronics.
  • a LED is placed on the cover for UV sterilization. Sterilization is started with the help of a button and there is a counter on it. It is mentioned that the process is over after 90 seconds. In addition, it is stated that the energy to be given to LEDs is provided by a battery.
  • UV lamp is used in this application. In other words, LED is not used.
  • the UV lamp is placed in a transparent waterproof structure in the water.
  • the light source contains mercury vapor, there is a risk of poisoning from drinking water. Although it is stated that the light source is placed in the waterproof part, if gas leaks during operation, it can poison the water. Because it is not understood whether it is a gas-tight structure and it is not mentioned in the specification. This can pose fatal consequences.
  • UV lamps were placed in the area where water can be placed. This reduces the amount of water to be cleaned. This shows design problems of this product.
  • UV lamp Since UV lamp is used, it has a narrow band of wavelength. Wide wavelength range is more efficient to inhibit (deactivate) different microorganisms. This is one of the important shortcomings of this product.
  • UV lamps mentioned in this application will heat up. This can shorten the life of certain mechanical and electrical parts. In addition, maintenance time intervals will be shortened, too.
  • the product aims to clean the water put into a transparent flask. Sun rays are used as UV source. Although this application looks good in theory, it is doubtful how it can be applied in practice.
  • UV rays in sunlight do not contain rays in UV-C (200-280 nm wavelength) band, they cannot destroy many microorganisms, so complete sterilization cannot be achieved.
  • the water tank can be removed and installed;
  • the chamber can be disinfected after removal
  • the chamber is made of different materials and can be changed.
  • Present invention relates to a piezoelectric powered ultraviolet light portable water disinfection system that meets above-mentioned requirements, eliminates all disadvantages, and brings some additional advantages.

It is also suitable for use in all healthcare facilities that provide mobilized healthcare services. Thanks to this portable and energy generating structure, the invention can be used in many nature sports activities, as well as military and medical fields.
  • Another advantage of invention is that it does not change taste of water.
  • the taste, color, odor of the water sterilized by the invention does not change.
  • the invention does not leave any chemical residue in the water. Since no chemical is used in the process, the invention does not leave any residue or waste of an additional foreign substance in the water.
  • UV LEDs contains low energy consuming UV LEDs and destroys microorganisms that cannot be destroyed by chemical methods.
  • the invention is suitable for use anywhere and in all conditions, thanks to its wide variety of designs and high service life. It does not take much space in the design due to very small dimensions of LEDs. It can be manufactured in sizes that can be put in a bag or fit into a trouser pocket.
