FIG. 5 is a cross-sectional view showing a part of the electric toothbrush, and FIG. 6 is an exploded perspective view showing the head portion.

<A> Main body (FIGS. 1, 3, and 4)
The main body 1 has a shape and size that can be easily grasped by a hand, and is formed into a cylindrical shape with resin or the like.
A battery (not shown), a motor 10, a transmission member 2 and the like are accommodated inside the main body 1, and a switch 12 for turning the motor 10 on and off is provided outside.
The electrical wiring may be a simple one in which, for example, the motor 10, the battery, and the switch 12 are connected in series.
An eyewash 30 or a toothbrush 60 is attached to the upper part of the main body 1.
When the eyewasher 30 is attached, the portable eyewasher 3 is obtained, and when the toothbrush 60 is attached, the electric toothbrush 6 is obtained.
Hereinafter, the case of the portable eye washer 3 will be described.

<B> Eyewash (Figure 1)
The eye wash 30 includes a cup-shaped container 31 and a connection member 4.
The cup-shaped container 31 is greatly opened upward, and the upper end edge is inclined or curved. The cup-shaped container 31 is preferably made of an elastic resin or the like so as to be in close contact when pressed against the face.
The cup-shaped container 31 may be graduated so that the amount of the cleaning liquid (eyewash liquid) can be measured.
The connecting member 4 connects the cup-shaped container 31 to the main body 1 and includes an upper member 40 and a lower member 41. When the upper member 40 and the lower member 41 are assembled, the hollow portion 44 is formed, and the hollow member 44 and the hole 43 are provided with a transmission member 2 and a vibration generator which will be described later.
The convex part 42 of the upper member 40 is pushed into the concave part 32 of the cup-shaped container 31 to constitute the eyewash device 30.

<C> Transmission member The transmission member 2 transmits the rotation of the motor 10 to the connection member 4 and is provided between the main body 1 and the eyewash 30.
The transmission member 2 is, for example, a joint that engages in a concavo-convex manner and engages in a concavo-convex manner when the eyewasher 30 is attached to the main body 1.
In this example, as can be seen from FIGS. 1 and 2, a female joint 20 having a cross-shaped concave portion is attached to the motor shaft 11, and a male joint having a cross-shaped convex portion that engages with the connecting member 4 is formed. 5 is provided, but may be reversed, and is not limited to a cross shape but may be a polygonal shape.
By providing the transmission member 2, the eyewash device 30 is detachable from the main body 1.

<D> Vibration generator The male joint 5 is rotatably supported on the connection member 4, and an eccentric weight 53 is attached to one end of the male joint 5. Since the male joint 5 is concavo-convexly engaged with the female joint 20 of the motor shaft 11, when the motor 10 rotates, the eccentric weight 53 also rotates together with the male joint 5, and the connecting member 4 vibrates due to the centrifugal force.
For this reason, the motor 10 and the eccentric weight 53 rotated by the motor 10 constitute a vibration generator.
A cup-shaped container 31 is attached to the connecting member 4, and the cleaning liquid inside can vibrate and wash the eyes.
In the figure, the rotary shaft 51 is pushed and coupled into the hole 50 of the male joint 5, and the rotary shaft 51 is rotatably supported by a bearing 52 and an eccentric weight 53 is attached (see FIG. 2). You may comprise the axis | shaft 51 by the integral object.

<E> Toothbrush (Figs. 4 and 5)
The toothbrush 60 includes an elongated arm 7 formed in a cylindrical shape and a head 8 in which a brush 80 is planted in a ring shape at the tip.
The electric toothbrush 6 is, for example, a type in which a brush 80 is rotated or swung to be polished circumferentially, and a head 8 is rotatable around a central axis 82.
A shaft 70 is rotatably attached to the inside of the arm 7. A cross-shaped male joint 71 is formed at the rear end of the shaft 70 as in the case of the portable eye washer 3 and is engaged with the female joint 20 of the motor shaft 11 to form the transmission member 2 (FIG. 5). ).

<F> Vibration generator A transmission pin 73 is eccentrically attached to the step portion 72 (head 8 side) of the shaft 70 with respect to the motor shaft 11.
A bifurcated projection 81 is provided on the end face of the head 8 in parallel with the central axis 82, and the bifurcated projection 81 is engaged so as to sandwich the transmission pin 73 (see FIG. 6). As the shaft 70 rotates, the head 8 swings around the central shaft 82 at a high speed through the bifurcated protrusion 81 by the amount of eccentricity of the transmission pin 73.
For this reason, the motor 10 and the transmission pin 73 rotated by the motor 10 constitute a vibration generating device of the head 8.

<E> Action When used as the portable eyewasher 3, the convex part 42 of the upper member 40 is pushed into the concave part 32 of the cup-shaped container 31, and the male joint 5 and the female joint 20 are fitted to the main body 1 while engaging the concave and convex portions. (FIGS. 1 and 3).
Next, the cleaning liquid is poured into the cup-shaped container 31, and the periphery of the eyes is pressed against the upper end edge of the cup-shaped container 31 to be brought into close contact therewith.
When the motor 10 is rotated by operating the switch 12 in this state, the eccentric weight 53 rotates via the transmission member 2. Since the eccentric weight 53 is attached to the rotating shaft 51 in an eccentric state, the cup-shaped container 31 vibrates together with the connecting member 4 as the motor 10 rotates at high speed. The cleaning liquid in the cup-shaped container 31 vibrates and can wash eyes.
When ending the eye wash, the switch 12 may be operated to stop the rotation of the motor 10.
When used as the electric toothbrush 6, the eyewasher 30 is pulled out from the main body 1, and the male joint 71 of the toothbrush 60 is attached to the female joint 20 of the motor shaft 11 in an uneven manner (FIGS. 4 and 5).
As in the case of the portable eyewasher 3, when the motor 10 is rotated by operating the switch 12, the transmission pin 73 that is eccentric with respect to the motor shaft 11 rotates, and the bifurcated protrusion that engages with this The head 8 swings at a high speed via 81. Accordingly, the brush 80 vibrates together with the head 8, and the teeth can be brushed.
In the present invention, the joints 5, 20, 71 that engage with each other are used, so that the eyewasher 30 or the toothbrush 60 can be easily mounted by simply inserting it into the main body 1.
