technical field

The invention relates to a water purifier, in particular to a water purifier with a sterilizing function.

Background technique

Ultraviolet rays refer to sunlight with a wavelength between 200nm and 380nm, including 3 types: UV-A with a wavelength of 315nm to 380nm, UV-B with a wavelength of 280nm to 315nm, and UV-C with a wavelength of 200nm to 280nm. About 13% of the sun's rays (290nm-2000nm) reaching the earth's surface are ultraviolet rays, of which UV-A accounts for 97%, UV-B accounts for 3%, and UV-C is close to 0. Only UV-A and UV-B are harmful to human skin. UV-A light in ultraviolet rays has strong penetrating power and can penetrate most transparent glass and plastics. It can be used in ultraviolet light therapy, document and banknote anti-counterfeiting detectors, photocatalysts, and air purification. UV-B light has medium penetrating power, and its shorter wavelength will be absorbed by transparent glass, which can be used for health care and plant growth promotion. UV-C light has the weakest penetrating ability and cannot penetrate most transparent glass and plastics, so it can be used for sterilization and floatation.

We know that ultraviolet rays can be used for disinfection and sterilization. But what really has a bactericidal effect is the UV-C wave ultraviolet light. Ultraviolet sterilization is very efficient. The sterilization effect is generally completed within one second, and it has a broad spectrum of sterilization. It can kill almost all bacteria and viruses with high efficiency and will not cause secondary pollution.

With the development of science and technology, LED has been widely used, but besides lighting, LED also has the most important function, which is sterilization. The LED germicidal lamp does not need to be converted into visible light, and the wavelength of 253.7nm can play a very good bactericidal effect. This is because there is a rule in the absorption spectrum of light waves by cells. The LED ultraviolet light at 250-270nm has the largest absorption and is used The absorbed LED ultraviolet rays actually act on the genetic material of the cell, namely DNA, which acts as a photochemical effect. The energy of the LED ultraviolet photons is absorbed by the base pairs in the DNA, causing the genetic material to mutate, causing the bacteria to die immediately or cannot reproduce Offspring, to achieve the purpose of sterilization. In addition to LED germicidal lamps, the current miniaturized low-voltage quartz tube ultraviolet germicidal lamps have been industrialized. With the application and development of cathode technology, cold cathode lamps have made breakthroughs in technology. It is better than hot cathode lamps. Low-pressure mercury lamps consume 90% less energy and have many times longer lifespans. In order to meet the needs of different use environments, the size of the cathode of the lamp is designed according to its rated current during operation. For every 1% increase in current, the life will be shortened by 1.7%; the starting voltage of the lamp is not only related to the gas pressure in the lamp, but also related to The pole distance of the lamp is related, so the starting voltage of the lamp must be controlled in the process of making the lamp. The gas generally uses argon or neon-argon mixed gas. The starting electronic circuit board of the cold cathode lamp speeds up the start-up time of the lamp. Generally, 12V, 6V, and 3V DC power sources are used to make the lamp more applicable. The cold cathode lamp germicidal lamp has the characteristics of small size, long life, large ultraviolet output and low temperature.

At present, we use ultraviolet lamps to disinfect water sources. We generally use large-scale special equipment, which are generally large in size and very expensive in price. For ordinary families, they cannot be widely used.
