It may wear out along the direction of the reciprocating movement and cause a permanent map. It has a downside that can be.

In addition, since the tongue cleaning unit according to the prior art is integrally formed on the bristles, liquids such as toothpaste, water, and saliva are accumulated on the tongue cleaning unit, which reduces cleaning efficiency, and cannot be separately cleaned and managed by separating from the bristles. , It has a disadvantage that the tongue cleaning unit cannot be replaced to suit the user's oral shape or the shape of the tongue.

In addition, since the bristle part of the oral electric toothbrush according to the prior art is laminated with a silicone material on top of a plastic material for transmitting reciprocating motion, vibration cannot be efficiently transmitted or may be attenuated, so the brush head from the motor unit The efficiency of transmitting the reciprocating motion force to the negative housing is very low, and as a result, the vibration force in the silicon protrusion is relatively very small, and the cleaning efficiency is slightly lowered.

Accordingly, there is an urgent need to develop technology as a high-quality and highly efficient oral electric toothbrush required by users who require premium products.

It includes a sub-diaphragm 320 formed, and a detachable tongue cleaning unit 300 having a silicon pad portion 330 that surrounds the sub-diaphragm 320 and has an uneven shape portion 331 formed on the upper and lower surfaces thereof.

In addition, the oral-type electric toothbrush (10a) is for directly providing vibration to the connecting bar (310a) of the tongue cleaning unit (300) and the extension bars (211a, 212a) respectively extending from the plurality of main diaphragm (200a) It includes a body part 500 provided with a plurality of vibrators 530.

In particular, referring to FIG. 6 or 7, the main diaphragm 200a is configured to be separated into a first main diaphragm 201a and a second main diaphragm 202a in a state in which the spaced distance G is maintained from each other. The sub-diaphragm 320 of the tongue washing unit 300 is also in a spaced state. In addition, although not shown in each of the first main diaphragm 201a and the second main diaphragm 202a, a weight or the vertical plate 230 mentioned in the first embodiment may be further formed.

Therefore, the first main diaphragm 201a, the second main diaphragm 202a, and the sub diaphragm 320 can perform independent vibrations, respectively, can independently generate vibrations, and can be in the vertical direction and the left and right directions or There is an advantage that the movement in the front and rear direction can be made independently.

For example, the first main diaphragm 201a has an English U-shape corresponding to the housing 110 of the bristle portion 100 and has a shape erected along the Z-axis direction. The first main diaphragm 201a is vertically disposed in the housing 110 along the extension direction of the housing so as to generate vertical vibration in the bristles 100.

On the other hand, the second main diaphragm 202a has a relatively smaller radius of curvature than the first main diaphragm 201a, and although it is in an English U-shape corresponding to the housing 110 of the bristles 100, it is placed on the XY plane. It has a shape that is. This second main diaphragm 202a is spaced apart from the first main diaphragm 201a by the spacing G in order to generate horizontal vibration in the bristles 100 and the extension direction of the housing 110 It is arranged horizontally along the way.

In particular, the first main diaphragm 201a is formed on the outside thereof, and includes a first extension bar 211a extending toward the toothbrush socket part 400. At this time, since the end of the first extension bar 211a may be further formed with a magnet portion of the same or similar type as mentioned above, coupling and binding with the vibrator 530 to be described later may be easily achieved.

In addition, the first main diaphragm 201a is separated from the first through hole 240 for passing the second extension bar 212a extending from the second main diaphragm 202a and the first through hole 240 It includes a second through-hole 250 for passing through the connecting bar 310a of the tongue cleaning unit 300 based on the position. At this time, the first through hole 240 and the second through hole 250 may be long or simple circular holes, and the hole size is relatively larger than the diameter of the connecting bar 310a or the second extension bar 212a. Therefore, there is an advantage that mutual interference can be made or minimized during vibration transmission.

The second main diaphragm 202a is also provided with a bent portion 260 that may not contact the connecting bar 310a or may reduce interference. Since the connecting bar 310a of the tongue cleaning part 300 is located based on a position spaced below the bottom of the bent part 260, the vibration of the second main diaphragm 202a also does not affect the sub diaphragm 320. May not.

In addition, the ends of each of the connecting bar 310a, the first extension bar 211a, and the second extension bar 212a may be disposed inside the connection passage 401a of the toothbrush socket part 400, and the body part When the 500 and the bristle part 100 are combined, each of the vibration bars 510 for each vibrator 530 may be connected through the corresponding connection hole 521 formed in the reinforcing part 520a of the body part 500. have.

8 is a block diagram showing the internal configuration of the bristles and the main body shown in FIG.

Referring to FIG. 8, the vibrator 530 of the main body 500 may be formed of a plurality (eg, three) capable of simultaneous operation according to individual operation or mode selection.

For example, the vibrator 530 includes a Z-axis vibrator 531 providing vertical vibration to the first extension bar 211a of the first main diaphragm 201a, and a second extension bar of the second main diaphragm 202a. An X-axis vibrator 532 that provides left and right vibration to 212a, and a Y-axis vibrator 533 that provides front and rear vibration to the connecting bar 310a of the sub-diaphragm 320 may be formed.

In particular, the sub-diaphragm 320 vibrates the tongue cleaning unit 300 in the longitudinal direction of the tongue, that is, in the front-rear direction (for example, in the Y-axis direction) while operating independently with respect to the bristle part 100, thereby safeguarding the tongue and the palate. And it has the advantage of being able to wash efficiently.
