Description
Technical field
The invention relates to a kind of ullrasonic spraying toothbrush, and its atomization being mainly characterized by utilizing gas-liquid two-phase and crushing mechanism, the ultrasound wave sent in conjunction with ultrasonic system, to tooth, particularly teeth space is cleaned.
Background technology
Many time-honoureds the most once had the way rubbing tooth of brushing teeth with twig or spile in the world, and another kind of common method is to rub tooth with sodium bicarbonate or Chalk.Data according to U.S.'s stomatology meeting represents, first toothbrush is by Chinese emperors bright filial piety ancestor in invention in 1498 in the world, and method is that short hard Pilus Sus domestica is injected a fulcra on the handle.The method of west tradition cleaning tooth is to rub, with one block of cloth waste, tooth of brushing teeth, and the method is to having existed less than ancient rome era.Toothbrush occurs to the 17th century side, is just widely current to 19th century.Du Pont chemical industry in 1938 release the toothbrush replacing animal wool with synthetic fibers (majority is nylon), make the toothbrush of bristle with nylon yarn for first and list on February 24th, 1.
Mankind ancestors early have the custom gargled, brush teeth, and just it has been found that cross the tooth of the instrument the earliest rod in cleaning oral cavity in the king coffin pit of B.C. 3000 Sumerian Wu Er city-states, can use fortnight for one.At ancient Greek and Roman period, people make dentifrice with animal bone ash, clear up oral cavity, and also some primitive tribe's Linesless charcoal, saline, fine sand, branch clears up tooth., one end being smashed to pieces, makes brush, be used for clearing up teeth space and brushing teeth, referred to as Miswak, is a kind of natural toothbrush, analyzes according to scientist, and this branch is fluorine-containing and Saponin, can prevent decayed tooth, and have analgesic effect.
Chinese just understood take care of one's teeth important before more than 2000 years.The reason just batch going out to cause dental caries in " Records of the Historian storehouse public affairs biography " is " food and do not gargle ".In " Book of Rites ": " ringing at the beginning of chicken, salty washing is coughed " just explanation people there has been the custom gargled.Ancients clear up oral cavity and tooth finger and Ramulus Salicis Babylonicae.In Dunhuang frescoes " labor degree jaw sage figure ", being decorated with a Buddhist monk, squat down on the ground, left hand holds gargle drinking bottle, wipes nipper with right hand middle finger.In the Tang Dynasty, people make brush with Ramulus Salicis Babylonicae, dip in liquid medicine and wipe tooth.Song dynasty, someone advocates that morning and evening every day Ramulus Salicis Babylonicae wipes tooth twice, and formally there is " toothbrush " word in the Yuan Dynasty, Guo Yu poem medium cloud: " head day posted by Antarctica's toothbrush, and a tired gold number is washed in de-sludging." society of Yuan Dynasty elite toothbrush, common people still use Ramulus Salicis Babylonicae, and the tooth powder of wiping that Chinese herbal medicine is developed into is brushed teeth, and according to another archaeological discovery, China is distant for two fulcra handle of being unearthed in ancient tomb before more than 1000 year.Visible China takes than Europe just the toothbrush in similar modern times for Zao more than 600 years.
In Europe, first toothbrush is invented in London in 1780 by Britain's cobbler's William's Ellis.William's Ellis is arrested by London authorities because violating sedition crime, is put into the most again notorious Newgate.He is different with most of prisoners, is good at pondering a problem with the brain of oneself.In one early morning, he is just by common mode little pieces of cloth oneself tooth of scouring, and a thought has rushed in suddenly his brain: if brushing teeth tooth with a small brushes, more more convenient than the tooth that uses cloth to wipe with the most more effective？When having supper, a meat bone is stealthily loaded pocket and takes back the prison cell of oneself by him, has wanted some bristles to a very friendly guard again.He wore into a thin rod bone, bored a little aperture above, then a branch of for bristles bundle has been injected aperture at night this day, and by they trimmed.Like this, first toothbrush in the world at the prison in be born！After leaving prison, Ellis has organized the toothbrush factory of oneself.He is successful, because people are ready to replace original little pieces of cloth with toothbrush.The company that Ai Disi foundes the most still is producing toothbrush.
Toothbrush can be divided into ordinary toothbrush, Spraying tooth brush, electric toothbrush and ultrasonic tooth-bruss etc. by action principle.
The head shapes of ordinary toothbrush is generally square and brilliant.Square brush can effectively clean each surface of tooth.The end relatively squared design of this kind of brush of diamond is point, cleans in being easier to go deep into oral cavity.Toothbrush possesses the brush of any shape, can clean tooth, but the size of brush is necessary for needing to consider oral cavity size, degree and the personal habits etc. of dehiscing factor.Use small and exquisite brush, in order to depths, oral cavity can be goed deep into, it is ensured that flexible rotating as far as possible, clean back teeth.But the most unified standard.Pediatric Oral Emergency should select to meet the toothbrush for children at its age.
Spraying tooth brush is the instrument of atomized liquid toothpaste, when brushing teeth with Spraying tooth brush, it liquid tooth paste can be sprayed onto on tooth, Spraying tooth brush is divided into hand spray hand spray toothbrush toothbrush and electric atomizing toothbrush.
Hand spray toothbrush has installed a head toothbrushes additional exactly on compression bottle, and bottle uses as handle.Hand spray toothbrush be technically characterized in that the compression bottle in handle, built with liquid tooth paste, is provided with toothpaste passage and spout on the head, spout is hidden in toothbrush scopular, and liquid tooth paste sprays from spout；Being additionally provided with a flexible glue check valve at nozzle and block spout, flexible glue check valve, for the sealing of spout, prevents antibacterial and saliva from entering in toothpaste passage, it is ensured that the toothpaste quality in toothpaste passage.
