Oral cavity cleaner including mouthpiece
An oral cavity cleaner according to the present disclosure includes: a handle including an inflow path through which washing water flows; and a mouthpiece having spray holes for spraying the washing water into an oral cavity, in which the mouthpiece includes: a labial surface corresponding portion formed at a position facing labial surfaces of teeth; a buccal surface corresponding portion connected to the labial surface corresponding portion and formed at a position facing buccal surfaces of the teeth; a lingual surface corresponding portion formed at a position facing lingual surfaces of the teeth; and an intermediation portion configured to connect the labial surface corresponding portion and the lingual surface corresponding portion and having two opposite ends starting from a connection point between the labial surface corresponding portion and the lingual surface corresponding portion.
1 . An oral cavity cleaner comprising:
a handle comprising an inflow path configured to allow washing water to flow therethrough; and
a mouthpiece connected to the inflow path and comprising:
a plurality of spray holes configured to spray the washing water into an oral cavity;
a flow path formed inside the mouthpiece and configured to direct the washing water from the inflow path to the spray holes; and
a plurality of water stoppers disposed inside the mouthpiece, located on the flow path toward the spray holes,
wherein each water stopper is disposed in a flow direction of the washing water and defines a plurality of reservoirs that guides a part of the washing water to allow the part of the washing water to flow reversely.
2 . The oral cavity cleaner of claim 1 , further comprising a plurality of spray grooves, wherein each spray groove is formed between each pair of the plurality of water stoppers, each spray groove being configured to guide the washing water to flow toward the spray holes.
3 . The oral cavity cleaner of claim 1 , wherein the plurality of reservoirs are formed between the plurality of water stoppers and configured to store the washing water.
4 . The oral cavity cleaner of claim 1 , wherein each water stopper is elongated in an upward/downward direction, and a center of each water stopper has a flow hole through which the washing water flows.
5 . An oral cavity cleaner comprising:
a mouthpiece comprising a plurality of reservoirs, each reservoir being formed inside the mouthpiece and fluidly connected to receive washing water,
a spray hole formed in each reservoir and configured to spray the washing water into an oral cavity; and
a plurality of water stoppers, each water stopper disposed between each pair of the plurality of reservoirs and configured to separate the plurality of reservoirs from one another,
wherein each reservoir is configured to temporarily store the washing water before the washing water is sprayed through the respective spray hole.
6 . The oral cavity cleaner of claim 5 , wherein the mouthpiece has a spray groove configured to guide the washing water introduced into each reservoir in a direction toward the spray hole.
7 . The oral cavity cleaner of claim 5 , wherein volumes of the plurality of reservoirs gradually increase rearward.
8 . The oral cavity cleaner of claim 5 , wherein each water stopper has a flow hole through which the washing water, which is supplied and exceeds a washing water storage capacity of each reservoir, flows to another reservoir of the plurality of reservoirs.
9 . An oral cavity cleaner comprising:
a handle comprising an inflow path configured to allow washing water to flow therethrough; and
a mouthpiece comprising a plurality of water stoppers formed inside the mouthpiece and disposed along a flow direction of the washing water before the washing water is sprayed into an oral cavity,
wherein the plurality of water stoppers define a plurality of reservoirs formed inside the mouthpiece, and one or more spray holes configured to spray the washing water into the oral cavity are formed in the reservoirs.
10 . The oral cavity cleaner of claim 9 , wherein the water stoppers are vertically formed to circulate the introduced washing water in an upward/downward direction.
