Canteen with sterilization function

Abstract

To provide a canteen with a sterilization function capable of utilizing as drinking water even when a power source is blocked at an emergency evacuation site due to earthquake or typhoon at outside camping site to which a power source of the present invention is not connected.SOLUTION: Open the upper lid 3 of the water storage container and pour raw water from above, then close the lid. Next, when a switch 9 is turned on, a deep ultraviolet LED 4 starts irradiating the water inside the water storage section 2. At the same time, the display section lights up to indicate that irradiation, i.e., sterilization, is in progress, and the water stored in the water storage section is sterilized. When taking out the sterilized water, turn off the switch, open the lid, tilt a main body of a canteen, and pour out the sterilized water. This effectively inactivates various viruses that may be present in the raw water put into the water storage section of the canteen and sterilizes bacteria, ensuring safe water.SELECTED DRAWING: Figure 2

Description

[Technical Field]

[0001] The sterilizing water bottle of the present invention can be used to purify clear streams and well water at outdoor campsites without electricity, to purify drinking water for emergencies such as disasters, and to purify tap water and well water in ordinary households. Furthermore, the product of the present invention does not use chemical water sterilization methods such as conventional chlorine agents, but rather uses a physical sterilization method in which the target water is irradiated with deep-ultraviolet LED light with a wavelength of 220 to 300 nm, eliminating the risk of residues that are common with chemical sterilization and making it safe for both the environment and humans. Another feature of the water bottle of the present invention is its ability to inactivate various viruses and sterilize various bacteria that may be contained in the water stored in the water storage container. [Background technology]

[0002] Generally, sterilization of water stored in water bottles used outdoors where there is no electricity has not been widely practiced until now. However, as hygiene awareness in daily life continues to increase and there are concerns about the spread of various viruses and bacteria in evacuation shelters in the event of a natural disaster, there is a demand for water bottle products with sterilization functions that are safe for the human body and effective. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6899968 Summary of the Invention [Problem to be solved by the invention] In Patent Document 1, a water treatment device (1) applies an impact to water (11) to be treated using an impact application unit (4). The impact application unit (4) sterilizes the water (11) by utilizing cavitation generated in the water (11) by the shock waves generated by the impact. The impact application unit (4) applies kinetic energy generated when an energy storage device (7) transitions from an energy storage state to an energy release state to an impact application surface (5b) of a valve (5). Shock waves are generated in the water (11) from a shock wave generation surface (5a) of the valve (5). This patent document describes a water treatment device that applies an impact to the water (11) to be treated using the impact application unit (4) in a water container and utilizes cavitation generated in the water (11) by the shock waves generated by the impact. Because this device sterilizes the water (11) by utilizing the cavitation generated in the water (11) by the shock waves generated by the impact, the device has a complex and large structure, making it difficult to manufacture. It also has limited sterilization performance. Conventional methods for sterilizing microorganisms such as fungi present in water include methods using chemicals, fine membranes, ozone, ultraviolet light, and shock waves. Each of the above methods has its own advantages and disadvantages when it comes to sterilization, and no technology satisfies all requirements. Chemicals leave behind chemical residues that require cleaning, and fine membranes cannot kill bacteria before capturing them. Ozone also requires complex concentration management and produces an odor, while ultraviolet light uses mercury in the lamp, which places a heavy burden on the environment and restricts its manufacture and sale. Shock waves also have complex structures and require a high-voltage power source, which poses challenges to their sterilization effectiveness.

[0004] The present invention was made in consideration of the above, and aims to solve all of the problems of Prior Art Document 1 and conventional general water disinfection technologies. The deep-ultraviolet LED used in the present invention has a wavelength of 220 to 300 nm, and university research institutes, companies, etc. have published papers and other data demonstrating its effectiveness in inactivating the novel coronavirus and disinfecting all common bacteria, with a disinfection rate of 99% or more under specific conditions. [Means for solving the problem]

[0005] An embodiment of the sterilizing water bottle of the present invention will be described. The sterilizing water bottle of the present invention comprises a vertically elongated cylindrical water bottle body 1 made of metal or resin material, a water storage section 2 built into the water bottle body 1, an opening / closing lid 3 at the top of the water storage section 2, a deep-ultraviolet LED 4 attached to the bottom of the water storage section 2 and irradiating light into the water storage section, an ultraviolet-transmitting plate 5 attached to the outer wall of the bottom of the water storage section 2, a handle 6 attached to the top of the water bottle body 1, a battery section 7 in the bottom cavity of the water bottle body 1, a control section 8, a switch 9 and an indicator light section 10 on the side of the lower body, and a bottom cover 13. As an additional function, a thin solar panel 11 that can be attached to a curved surface can be attached to the side of the water bottle body to charge and store electricity using sunlight. Furthermore, as an additional function, an outlet section 12 is provided on the body for use with a power source. To use the sterilized water bottle of the present invention, open the opening and closing lid on the top of the water storage container, pour in raw water from the top, and close the opening and closing lid. Next, when the switch is turned on, the deep-ultraviolet LED begins irradiating the water in the water storage section, and at the same time, the display lights up to indicate that irradiation is in progress, i.e., sterilization is in progress, and the water stored in the water storage section is sterilized. To remove the sterilized water, turn off the switch, open the opening and closing lid, and tilt the water bottle to remove the sterilized water. [Effects of the Invention]

[0006] According to the present invention, even when electricity is cut off at an outdoor campsite where there is no power supply or at an emergency evacuation site due to an earthquake or typhoon, well water or clean stream water can be put into a water bottle and sterilized by irradiation with the built-in deep-ultraviolet LED, making the water safe to drink.
