Technical Field

The invention belongs to the field of oral tooth cleaning tools, and particularly relates to a toothbrush with functions of decontamination, disinfection and sterilization.

Background

The hydroxyl radical (. OH) has extremely high oxidation potential and extremely strong oxidizing power, is second to fluorine in nature, can generate rapid chain reaction with most organic pollutants, can not selectively oxidize harmful substances into CO2, H2O or mineral salts, has no secondary pollution, and is the most effective method for removing the organic pollutants. OH is not an ion, but a group, i.e.does not exhibit electrical properties, cannot exist alone, can only be combined with other groups, and has a short lifetime, generally less than minus 4 seconds of 10, i.e.0.0001 seconds. The photochemical reaction is generated under the three conditions of ultraviolet ray, water and ozone on the atmosphere, and the ultraviolet ray disappears immediately.

The black teeth of the oral cavity of smokers and tea drinkers are widely existed, the main components of smoke stain and tea stain dental stain are compounds consisting of organic matters and bacteria, the general tooth cleaning method has poor effect or painful process, patients do not want to accept the method, and if the hydroxyl free radicals can clean, sterilize and disinfect the oral cavity teeth, the method is an improvement on oral hygiene.

In the description of the present invention, it is to be understood that the terms "front", "back", "etc. indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, but do not indicate or imply that the referenced devices or elements must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

As shown in figures 1-2, the toothbrush with disinfection function of the invention mainly comprises a toothbrush head 1 and a toothbrush handle 2. The shell of the toothbrush head 1 is made of disposable medical plastic, a cavity 11 is processed inside the toothbrush head 1, and the inner side surface of the cavity 11 is a polishing surface 12 made of arc-shaped aluminized materials and can be used for reflecting ultraviolet rays. The front side of the toothbrush head 1 is provided with a plurality of optical fiber brush hairs 3 and a water spray hole 4, the optical fiber brush is made of plastic optical fibers with the diameter of 0.2mm, and the plastic optical fibers are quartz optical fibers wrapped by plastic layers. The base of the fibre-optic bristles 3 extends into the cavity 11 so that ultraviolet radiation within the cavity can be directed out. The water spraying holes 4 are communicated with the cavity 11 and have the diameter of 0.8 mm. An inner retaining ring is arranged on the inner wall of the rear end of the toothbrush head 1, and a sealing rubber ring 13 for improving the sealing performance is arranged on the inner retaining ring. A circular cavity is formed in the toothbrush handle 2 for receiving a liquid conduit 5 and a fiber optic bundle 6. The front end of the toothbrush handle 2 is embedded with a quartz glass sheet 21, the front end of the liquid pipeline 5 penetrates through the quartz glass sheet 21 and extends into the cavity 11, the front end of the optical fiber bundle 6 is abutted against the quartz glass sheet 21, and ultraviolet rays pass through the quartz glass sheet through the optical fiber bundle and directly enter the cavity 11 because the quartz glass sheet is transparent. The toothbrush head 1 and the toothbrush handle 2 are connected into a whole in an inserting mode, and the toothbrush head is convenient to replace due to the design.

Because the invention is mostly used in oral hospitals, some conventional equipment is needed to be matched. As shown in fig. 3, a solution tank 7 is provided, and the solution tank 7 contains a mixed liquid of hydrogen peroxide and ferrous sulfate. The solution tank 7 is communicated with the rear end of the liquid pipeline through a booster pump 8 and a connecting hose. The ultraviolet generator 9 is 254 nm ultraviolet ray, is arranged at the tail end of the toothbrush handle and is communicated with the optical fiber bundle. The switches of the ultraviolet generator 9 and the booster pump 8 are arranged on the toothbrush handle, thus being convenient for the medical staff to operate and use.

Taking an example of cleaning teeth for a patient in an oral hospital, the toothbrush with the disinfection and sterilization functions provided by the invention has the following specific using process:

firstly, 1400ppm (1.4 ten-thousandth) ferrous sulfate (PH 3.5-4) is added into 700ppm (0.7 ten-thousandth) hydrogen peroxide to form mixed liquid, a switch is turned on, the mixed liquid is conveyed to a liquid pipeline from a solution tank by a booster pump to enter a cavity, and then the mixed liquid is sprayed into an oral cavity through a water spraying hole. Simultaneously, ultraviolet rays generated by the ultraviolet ray generator penetrate through the quartz glass sheet through the optical fiber bundle, enter the plurality of optical fiber brushes through the reflection of the polished surface, the ultraviolet rays irradiate hydrogen peroxide at the tip parts of the optical fiber brushes, and OH (hydroxyl radical), O (ozone) and O (simple substance oxygen ions) are instantaneously generated in liquid, so that the teeth are sterilized and disinfected, and meanwhile, tartar and dental plaque are removed. Since OH (hydroxyl radical), O (ozone) and O (simple substance oxygen ion) are unstable, they disappear after the ultraviolet irradiation is stopped, thereby ensuring the safety and handling of the present invention.
