Ultraviolet water sterilization device realizing electrification with friction

Abstract

The invention provides an ultraviolet water sterilization device realizing electrification with friction. The device comprises a mechanical energy input device, a planet gear speed increaser, a friction nanogenerator, a water pump and an ultraviolet lamp, wherein the output end of the mechanical energy input device is connected with an input shaft of the planet gear speed increaser and a rotor ofthe friction nanogenerator, and an output shaft of the planet gear speed increaser is connected with an input shaft of the water pump through a coupler; the ultraviolet lamp adopts a screw type or overflowing type and comprises a lamp tube, water pipes and first and second wire electrodes connected with first and second output ends of the friction nanogenerator, one end of each water pipe serves as a water inlet to be communicated with a water outlet of the water pump, and to-be-sterilized water is introduced into a water inlet of the water pump. the ultraviolet lamp and the friction nanogenerator are combined, high enough voltage is produced by collected mechanical movement under the effect of electrification with friction, rare gas in the ultraviolet lamp tube is broken down, the ultraviolet lamp tube emits ultraviolet, conversion from mechanical energy to light energy is realized, and the device is simple and portable.

Description

technical field [0001] The invention belongs to the technical field of ultraviolet sterilizing devices, in particular to an ultraviolet water sterilizing device utilizing friction to generate electricity. Background technique [0002] Ultraviolet (UV) sterilization is the mainstream method of water sterilization at present. The principle that ultraviolet rays with suitable wavelengths can destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in the cells of microorganisms to kill cells realizes sterilization and disinfection. Effect. The advantages of ultraviolet sterilization are mainly reflected in the following three aspects: first, the ultraviolet sterilization technology is relatively mature, and it does not produce any disinfection by-products; second, the ultraviolet sterilization speed is fast, and the sterilization effect is good; finally, its operation is safe and simple. Therefore, exploring a technology that does not rely on th...

Problems solved by technology

[0005] The disadvantages of this sterilizer are: the primary transformer and the secondary transformer need to be connected in the circuit, which makes the structure more complicated; the mains power is used as the energy source, and the scope of application is limited to areas with stable mains power supply. In the wild, disaster areas, etc. It cannot be used in areas that also require water sterilization

[0007] The disadvantage of this sterilizer is that the internal structure of the sterilizer is relatively complicated, and the increase in manufacturing cost exceeds the benefit of the sterilizing effect.

The way the sterilizer drives the ultraviolet lamp is consistent with the traditional way, without breaking through the limitation of the application range of the traditional ultraviolet lamp
