[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0011] In FIG. 1, reference numeral 1 denotes an ultrasonic oral irrigator according to an embodiment of the present invention.

[0012] As shown in FIG. 2, this ultrasonic oral irrigator 1 includes an intraoral mounting portion 3 to be mounted inside the oral cavity 2 and an operation portion 4 exposed outside the oral cavity 2. The outer shells of these intraoral mounting portion 3 and operation portion 4 are integrally formed of an insulating member.

[0013] The intraoral mounting portion 3 includes an ultrasonic vibration portion 5 to be inserted inside the oral cavity 2 and a connecting portion 6 that connects the ultrasonic vibration portion 5 and the operation portion 4. The operation portion 4 is configured to operate the ultrasonic vibration portion 5 from outside the oral cavity 2.

[0014] As shown in FIGS. 3 and 4, an ultrasonic vibrator 7 is embedded in the ultrasonic vibration portion 5, and this ultrasonic vibrator 7 is electrically connected to the operation portion 4 via the inside of the connecting portion 6.

[0015] Further, as shown in FIG. 5, the operation portion 4 is provided with a pulse oscillator 8, a battery 9, a switch 10, a charging USB socket 11, a pilot lamp 21, a timer 22, and a speaker 23, etc. The timer 22 counts down the time required for cleaning, and the speaker 23 is configured to notify the countdown of the timer 22 by sound.

[0016] The connecting portion 6 includes a retaining portion 12 that prevents the ultrasonic vibration portion 5 from coming out of the oral cavity 2.

[0017] This retaining portion 12 includes an overhanging portion 15 that projects outward from the connecting portion 6, and this overhanging portion 15 is configured to be interposed between the tooth 13 and the lip 14.

[0018] In addition, the connecting portion 6 includes a tooth-holding portion 16 held by the teeth 13 and a lip-holding portion 17 held by the lips 14. The tooth-holding portion 16 is provided between the retaining portion 12 and the ultrasonic vibration portion 5, and the lip-holding portion 17 is provided between the retaining portion 12 and the operation portion 4.

[0019] The cross-sectional shapes of the tooth-holding portion 16 and the lip-holding portion 17 may be circular or rounded rectangular.

[0020] In addition, the ultrasonic vibration portion 5 is formed in a flat and disk shape so as to be inserted onto the tongue, has a width larger than the width of the connecting portion 6, and has a height approximately the same as the height of the connecting portion 6.

[0021] Furthermore, the retaining portion 12 has a width larger than the width of the ultrasonic vibration portion 5 and a height larger than the height of the ultrasonic vibration portion 5.

[0022] Furthermore, the operation portion 4 is formed in a shape along the direction of the lips 14, has a width larger than the widths of the ultrasonic vibration portion 5 and the retaining portion 12, and has a height approximately the same as the height of the ultrasonic vibration portion 5.

[0023] Furthermore, the connecting portion 6 is formed in a drum shape in the shape between the ultrasonic vibration portion 5 and the retaining portion 12 and in the shape between the operation portion 4 and the retaining portion 12.

[0024] Furthermore, the operation portion 4 and the connecting portion 6 are arranged in an anchor shape in a plan view.

[0025] When using the ultrasonic oral cleaner 1 configured as described above, as shown in FIG. 6, the ultrasonic vibration portion 5 is inserted into the oral cavity 2 and set so as to be placed on the tongue 18 as shown in FIG. 1.

[0026] Also, by holding the tooth-holding portion 16 with the teeth 13 and holding the lip-holding portion 17 with the lips 14, the retaining portion 12 is positioned between the teeth 13 and the lips 14, and water is included in the oral cavity 2.

[0027] This prevents the ultrasonic vibrating unit 5 from coming out of the oral cavity 2, and also allows for the positioning of the ultrasonic vibrating unit 5.

[0028] <Variation> The ultrasonic vibration unit 5 described above may be configured as shown in Figures 7 to 10.

[0029] In Figures 7 to 10, components identical to those in Figures 1 to 6 are denoted by the same reference numerals, and their explanations are omitted.

[0030] In other words, the ultrasonic vibration unit 5 comprises a disc-shaped ultrasonic transducer 31 and a disc-shaped metal plate 32, for example, made of stainless steel, which is laminated on the upper surface of the ultrasonic transducer 31.

[0031] These ultrasonic transducers 31 and metal plates 32 are covered by an insulating member 33, except for a portion of the upper surface of the metal plate 32, for example, the central portion.

[0032] The insulating member 33 is provided with a pair of clamping parts 34 for clamping the ultrasonic transducer 31 and the metal plate 32 with teeth 13 on the left, right, top, and bottom via the insulating member 33.

[0033] Furthermore, in the central portion where the insulating member 33 is not provided, a mesh-like cover 35 is provided on the upper surface side of the metal plate 32 at a predetermined interval and connected to the insulating member 33.

[0034] Then, during cleaning, the clamping part 34 is clamped by the teeth 13 on the top, bottom, left, and right.

[0035] Furthermore, bubbles generated by the vibration of the ultrasonic transducer 31 are introduced into the oral cavity 2 through the mesh-like cover 35.

[0036] With the above configuration, a large ultrasonic transducer 31 that conforms to the shape of the teeth can be used.
