IoT solution: smart toothbrush disinfection device (ultraviolet, steam disinfection)

Maintaining good brushing habits is good for teeth health, but many people may not know that the toothbrushes we usually need to clean. Due to the contact with the tooth and the gum brush, the food residues in the mouth, the bacteria will enter the toothbrush, and the placement of the tooth is generally in a humid bathroom. This provides superior conditions for the reproduction of bacteria. Virus contaminated toothbrushes have become the root cause of dental disease.


Toothbrushes are used as cleaning teeth and are contaminated by a variety of germs in the mouth. Because they are in a humid and dark environment for a long time, they are easily breed of various germs. Especially when multiple toothbrushes are shared with a toothpaste, it is more likely to cause cross infection. Health causes damage. The only way to prevent the disease caused by toothbrushes is to prevent breeding bacteria and disinfect the toothbrush with ultraviolet lights. It is one of the most effective methods at present and easily completes the disinfection process.

Therefore, there is the birth of the development of a smart toothbrush disinfection solution! Let me introduce the functional characteristics of the development of the smart toothbrush disinfection device scheme!

1. Principles of smart toothbrush disinfectioner:


Using cold cathode ultraviolet lamps can emit ultraviolet rays with a wavelength of 253.7nm. It is used to use lower mercury steam pressure (<10-20Pa) to emit UV light waves. There are two main luminous spectrum lines:


One is 253.7nm, which can absorb ultraviolet rays in the deoxyrocytes (DNA), ribosaccharotic acid (RNA) and ribin in bacteria. After the bacterial absorption of ultraviolet rays, the DNA chain is broken, causing the cross -linking of nucleic acid and protein, killing the biological activity of nucleic acid, causing bacterial death;


The other is 185nm. The wavelength UV rays are used for high vacuum sterilization. Vacuum ultraviolet rays can cause oxygen and electricity in the air to produce ozone to achieve the purpose of purifying the air. Shortcomings.


Second, the technical principle of smart toothbrush disinfectant steam:

Ultraviolet radiation can kill bacterial cells and is often used to kill bacteria (such as tables) that are used in the air, but there are many corners, gaps, and regional ultraviolet rays between dark and toothbrush bristles cannot be reached. Even after several UV disinfection, there are potential surviving bacteria in your toothbrush brush.

Steaming technology using ultraviolet rays is proven to be the most effective way to kill bacteria. Steam disinfection is very natural and safe. There is no harmful chemical substance. Compared with ultraviolet rays, it is effectively clearing the germs. Even doctors and dentists rely on steam methods to disinfect the most!


Second, the functional characteristics of smart toothbrushes disinfectioner:

The ingenious structural design collects toothbrushes, toothpaste, cups, and other toiletries on the wall -mounted disinfectioner, saving space and beautiful;

Smart infrared induction, automatically turn on disinfection and sterilization mode when no one is induced;

Lithium batteries can be charged to ensure long battery life;


Solar photovoltaic is charged. When there is light, no matter the sun or the indoor light, it can be powered by the battery;
