Embodiment Construction

[0013] Embodiments of the invention will be described with reference to the accompanying drawings which form a part hereof. Referring to FIG. 2 , there are shown a head 1 formed by providing bristles 10 on one end side of a shaft 11 , and a handle portion 2 containing a power source (such as a battery, etc.) 20 . Included in the handle portion 2 is a drive shaft 21 , one end of which is connected to the head 1 ; an actuator 22 for moving the drive shaft 21 in an axially reciprocating manner, etc.; and a circuit board 24 . Also, there is an electrode 23 on the outer surface of the handle part 2 , and the head 1 has an electrode 13 near the root of the bristle 10 .

[0014] As shown in FIG. 1 , the electrode 23 is connected to the positive pole of the battery 20 via the external resistor Ro1 mounted on the circuit board 24 and the booster circuit 3 . In addition, the electrodes 13 of the head 1 communicate with each other via the conductive plate 12 installed in the shaft 11, t...

Abstract

A mouth cleaning device includes: a head portion provided with bristles and an electrode; and a handle portion provided with an electrode. In the mouth cleaning device, when an electric circuit is formed from one electrode to the other electrode via a human body by application of a voltage to the electrodes, a pulse current having a frequency of about 4000 Hz to about 15000 Hz flows therein.

Description

technical field [0001] The present invention relates to an oral cleaning device for improving oral hygiene by flowing a microcurrent in the oral cavity. Background technique [0002] For conventional oral cleaning devices, electronic toothbrushes or ionic toothbrushes are already known. Conventional oral cleaning devices remove tartar from teeth by flowing microcurrent in the oral cavity, thereby improving the cleaning effect of toothbrushing, metabolism of oral tissue, or blood flow. For example, Japanese Patent Publication No. 2560162 discloses a toothbrush comprising a head provided with bristles and a handle part containing a battery, wherein an electrode connected to one pole of the battery is provided on a part of the surface of the handle part , while the electrode connected to the other pole of the battery is set on the head. When the user inserts the head into the oral cavity while holding the handle part, microcurrent flows from the hand holding the handle part t...
