In particular, referring to FIG. 6 or 7, the main diaphragm 200a is divided into a first main diaphragm 201a and a second main diaphragm 202a in a state where a spaced interval G is maintained. The sub diaphragm 320 of the tongue cleaning unit 300 is also spaced apart. In addition, although not shown in each of the first main diaphragm 201a and the second main diaphragm 202a, a weight or a vertical plate 230 mentioned in the first embodiment may be further formed.

Accordingly, the first main diaphragm 201a, the second main diaphragm 202a, and the sub diaphragm 320 may each independently perform vibrations, and may generate independent vibrations, respectively, 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 a U-shaped shape corresponding to the housing 110 of the bristle part 100 and has a shape standing along the Z-axis direction. The first main diaphragm 201a is disposed vertically along the extension direction of the housing inside the housing 110 so as to generate vertical vibration in the bristle part 100.

On the other hand, the second main diaphragm 202a has a relatively small radius of curvature compared to the first main diaphragm 201a, and is in the U-shaped shape corresponding to the housing 110 of the bristle part 100, but lies in the XY plane. It has a shape. The second main diaphragm 202a extends the extension direction of the housing 110 in a state spaced apart from the first main diaphragm 201a by the separation gap G so as to generate horizontal vibration in the bristle part 100. It is arranged horizontally.

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 400. At this time, the end of the first extension bar (211a) may be further formed with a magnet part of the same or similar type as mentioned above, it can be easily coupled and combined with the exciter 530 to be described later.

In addition, the first main diaphragm 201a is spaced apart 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. Based on the position, the second through hole 250 for passing through the connecting bar 310a of the tongue washing unit 300. In this case, the first through hole 240 and the second through hole 250 may be a long hole or a simple circular hole, 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 can be minimized or mutual interference when transmitting vibration.

The second main diaphragm 202a is also formed with a bent portion 260 that can be in contact with the connecting bar 310a or can reduce interference. Since the connecting bar 310a of the tongue cleaning unit 300 is positioned based on the position spaced below the bottom of the bend 260, the vibration of the second main diaphragm 202a does not affect the sub diaphragm 320. You may not.

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

FIG. 8 is a block diagram illustrating an internal configuration of the bristle part and the main body part shown in FIG. 5.

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

For example, the exciter 530 is a Z-axis excitation 531 for providing vertical vibration to the first extension bar 211a of the first main diaphragm 201a, and the second extension bar of the second main diaphragm 202a. X-axis excitation 532 for providing left and right vibration to the 212a, and Y-axis excitation 533 for providing front and rear vibration to the connecting bar 310a of the sub-diaphragm 320.

In particular, the sub diaphragm 320 operates independently with respect to the bristles 100, thereby vibrating the tongue cleaning unit 300 in the longitudinal direction of the tongue bottom, that is, the front and rear direction (for example, the Y-axis direction), thereby securing the tongue and the palate. There is an advantage that can be cleaned efficiently.
