Description

A kind of portable tooth cleaning device

Technical field

The utility model relates to oral hygienes, and in particular to a kind of portable tooth cleaning device.

Background technique

Either the illness rate of developed country or developing country's odontopathy is all very high.The United Nations's health organization 2012 Bulletin points out " in world wide 60 ~ 90% school-ager and almost 100% adult suffers from saprodontia "；Adult suffers from periodontal disease Ratio is in majority state up to 90% or more.Odontopathy is most wide one of the chronic disease of global prevalence, the generation of odontopathy Will cause loss of tooth and also bring very big inconvenience on the living conditions to people, serious periodontal disease can also cause heart disease, Diabetes and nephrosis have close be associated with people's health.

According to the summary of scientists, the plaque at most removing 50% of brushing teeth, along with dental floss also at most removes 70% One of the reason of plaque, this is the human diseases for causing odontopathy most wide as prevalence.

Water dental floss (Water Flosser) is widely used also referred to as tooth flusher, dentistry injection water health-promoting apparatus.It is washing In tooth, therapeutic process, water dental floss is essential medical instrument, but other than dental hospital is using water dental floss, it is more next More families has also provided water dental floss for oneself, and the water dental floss of household is portable, portable water tooth currently on the market mostly Line mostly uses fixed water tank mode, use can not be connect with other containers, while such water dental floss occupied space volume is big Be inconvenient to be carried.

Although disclosing portable water dental floss in the prior art, such as application No. is 201520404600.4 China is practical New patent and application No. is 201710184501.3 Chinese invention patent, due to motor must waterproof, these schemes are often It is the side or lower part that water tank is set to shell, water tank and motor is provided separately, structure is lengthy and jumbled, is on the one hand easy to cause water Dental floss volume is excessive, on the other hand may be due to volumetric constraint, and water tank volume is too small, causes inconvenient for use.Additionally, due to motor Shaft and water tank between need to seal, be also easy to appear in use failure leak the case where, so as to cause motor damage It is bad.

It is to be not provided with water tank there are also some schemes, such as application No. is the sides by increasing the external water pipe connecting with tap Formula, but the program is (must be able to connect with external water pipe) required for the shape of the water outlet of tap, therefore So that using by biggish limitation, it cannot achieve and meet user and wish the needs of using whenever and wherever possible.
