Description

Oral care device {ORAL CARE DEVICE}

The present invention relates to an oral care device, and more particularly, to an oral care device configured to enable width adjustment.

The oral cavity is a very important organ for breathing and food intake. If the oral cavity is not kept clean, plaque and calculus may form around the teeth and gums.

Such plaque and tartar proliferate bacteria in the oral cavity, causing gum diseases such as periodontitis and gingivitis. To prevent such gum disease, an oral care device configured to sterilize oral bacteria and whiten teeth by irradiating LED light to teeth and gums has been developed.

Most of the conventional oral care devices are manufactured for the main purpose of tooth whitening, and are configured to irradiate LED light to the user's front teeth that are easily visible from the outside. That is, it is difficult for conventional oral care devices to irradiate LED light to the posterior teeth, which are molars and inner portions of teeth that are not visible from the outside.

That is, based on the base 110, the upper tooth accommodating space 101 is provided in the upper part, and the lower tooth accommodating space 102 is provided in the lower part.

The first labial partition wall portion 120 is provided on an outer rim of the base 110 . The first labial partition wall portion 120 protrudes upward from the base 110 to provide an upper tooth accommodating space 101 . The first labial partition wall portion 120 is made to be disposed on the front side of the teeth, that is, on the lip side, while the user is holding the oral care device 1000.

The first lingual partition wall portion 130 is provided on the inner rim of the base 110 . The first lingual partition wall portion 130 is spaced apart from the first labial partition wall part 120 and protrudes upward from the base 110 to form the upper tooth accommodating space 101 together with the first labial partition wall part 120. arrange The first lingual partition wall portion 130 is configured to be disposed on the rear side of the teeth, that is, on the tongue side, while the user is holding the oral care device 1000.

The second labial partition wall portion 140 and the second lingual partition wall portion 150 protrude downward from the base 110 and form a lower tooth accommodating space 102 .

The first lingual partition 130 and the second lingual partition 150 form a space 104 corresponding to the width adjustment space 103 and are spaced apart from each other.

Accordingly, when a certain or more external force is applied to the oral care device 1000, the width of the space between the width adjustment space 103 and the separation space 104 of the oral care device 1000 is reduced, and the width of the oral care device 1000 is reduced. can Due to the structural form of the bracket 100, the user can more conveniently insert the oral care device 1000 into the oral cavity.

Referring to (a) of Figure 4, the bracket 100 is provided with an anterior insertion space (S1) into which the user's front teeth are inserted and a posterior insertion space (S2) into which the user's molars are inserted, but the anterior insertion space (S1) And posterior teeth insertion space (S2) may be made at different intervals. Posterior tooth insertion space (S2) can be formed at wider intervals than the anterior insertion space (S1). In this way, by forming different intervals between the anterior insertion space (S1) and the posterior insertion space (S2) according to the thickness of the teeth, the teeth and interdental papillae from the light source (250, 260, 270) (to the gap between the teeth) It is possible to increase the irradiation efficiency of the light irradiated to the gum). Such a bracket 100 can increase light irradiation efficiency by increasing light adhesion between teeth and interdental papillae and the light sources 250 , 260 , and 270 .

Referring to (b) of Figure 4, the height (H2) of the posterior side of the partition wall portion may be formed lower than the height (H1) of the anterior portion. This is because the gap between the upper and lower posterior teeth is narrower than the anterior gap in a state where the user opens the mouth, so the height H2 of the posterior part of the partition wall is lower than the height H1 of the anterior part so that the user can use the oral care device ( 1000) is to be smoothly inserted into the oral cavity.

Meanwhile, the barrier rib portion may protrude from the base 110 in a form widening. This is to form a wider irradiation range of light when the light sources 250, 260, and 270 irradiate light to teeth and interdental papillae. Therefore, treatment and prevention of teeth and interdental papillae can be made more effective.

An inclination angle (A) of the partition wall portion obliquely protruding from the base 110 may be made of 120 to 130 ° based on the base 110 . A more preferable inclination angle (A) of the partition wall portion may be made of 125°.
