The vibrating device may further include a wire having one end wound on the rotating shaft and the other end connected to the separating part separated from the other end of the body.

As described above, according to the embodiment of the present invention, the spring is applied instead of the electric device as the structure for generating vibration, so that the production cost can be reduced, the weight can be reduced, and the size can be reduced.

In addition, since the spring with a semi-permanent lifetime is applied, the lifetime limitation can be overcome.

Furthermore, the vibration caused by the spring is generated for a predetermined time according to the amount of winding of the spring, so that the timer function can be naturally realized.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a vibration device showing a longitudinal vibration generator according to an embodiment of the present invention.

1, the vibration device 1 according to the embodiment of the present invention includes a body 10, a vibrating unit 12, an operating member 14, a manual winding 20, a rotating shaft 22, (24), an interlocking gear (26), and a connecting rod (30).

The body 10 is a housing having a hollow cylindrical shape, and a vibration generating portion of the vibration device 1 is embedded in the hollow. In addition, the body 10 may function as a handle of a user, and may be designed to have a hollow cylindrical shape according to a design of a person skilled in the art (hereinafter referred to as a person skilled in the art) The shape can be modified on the basis of.

The vibrating unit 12 is movably coupled to one end of the body 10. The vibrating unit 12 is a vibrating unit that receives vibrations generated from the vibration generating unit of the vibrating device 1 and vibrates.

The operation member 14 is coupled to one end of the vibration unit 12 so as to move integrally with the vibration unit 12. Further, the operation member 14 can be replaced as a consumable item when it is replaced at a predetermined number of times. For example, the actuating member 14 may be a toothbrush brush (see Figures 3 and 4), but is not limited thereto.

One end of the spring 20 is fixed to the body 10 and the other end is rotatably connected to the body 10. In addition, as the other end of the spring 20 rotates, the spring 20 is wound to have elastic energy. The spring 20 is a spiral-wound spring of a thin band-like metal plate, which accumulates the elastic energy of the metal plate when wound and uses the force to be released in its original state as a power source. So that detailed description will be omitted.

The rotary shaft 22 is rotatably supported by the body 10 and the other end of the spring 20 is fixed to the rotary shaft 22. Thus, the other end of the spring 20 is rotatably connected to the body 10.

The spiral gear 24 rotates integrally with the rotary shaft 22 about the rotary shaft 22.

The interlocking gear 26 is gear-engaged with the spiral gear 24. That is, the gear teeth of the interlocking gear 26 engage with the gear teeth of the spring 24.

One end of the connecting rod 30 is connected to the vibrating part 12 and the other end is connected to the interlocking gear 26. That is, the connection rod 30 connects the interlocking gear 26 and the vibration unit 12. The other end of the connecting rod 30 is rotatably connected eccentrically to a portion of the interlocking gear 26 spaced from the center of rotation of the interlocking gear 26 by a predetermined distance. Accordingly, the vibrating part 12 connected to one end of the connecting rod 30 vibrates in the longitudinal direction according to the rotation of the interlocking gear 26. Here, the longitudinal direction means the longitudinal direction of the cylindrical body 10.

2 is a block diagram of a vibration device showing a width direction vibration generating unit according to an embodiment of the present invention.

As shown in Fig. 2, the vibration device 1 according to the embodiment of the present invention further includes a diaphragm 32. Fig.

The vibration generating portion of the vibration device 1 is divided into a longitudinal vibration generating portion such as the interlocking gear 26 and the connecting rod 30 described above and a lateral vibration generating portion such as a vibration plate 32 to be described later.

One end of the diaphragm 32 is connected to the vibration unit 12 and the other end of the diaphragm 32 is in contact with the gear teeth of the spring 24. Here, the diaphragm 32 may be a metal plate vibrating with external force. In addition, a periodic and repetitive external force can be applied to the other end of the diaphragm 32, which is in contact with the gear teeth of the spur gear 24, in accordance with the rotation of the spur gear 24. Therefore, the vibrating portion 12 connected to one end of the diaphragm 32 vibrates in the width direction according to the rotation of the spiral gear 24. Here, the width direction means the radial direction of the cylindrical body 10.

FIG. 3 is a view showing a configuration of winding a spring according to one embodiment of the present invention.

3, the vibrating device 1 according to one embodiment of the present invention is provided with a dial 40 as a constitution for winding the above-mentioned spring 20.

The dial 40 is disposed outside the body 10 and is disposed at a position corresponding to the spiral gear 24 disposed in the body 10. The dial 40 itself may be a handle, and a protrusion 42 may be formed to serve as a handle. Further, the dial 40 rotates integrally with the rotation shaft 22 and the spiral gear 24. Thus, by rotating the dial 40 by the user, the spring can be wound.

FIGS. 4 to 5 are views showing a configuration of winding a spring according to another embodiment of the present invention.

4 to 5, the vibrating device 1 according to another embodiment of the present invention is provided with a wire 50 as a constitution of winding the above-mentioned spring 20.

The wire (50) is provided so that one end thereof is wound on the rotation shaft (22). The other end of the wire (50) is connected to a separator (16) which is separated from the other end of the body (10). Further, the separator 16 is provided with a ring 18 so that the user can easily pull the separator 16.

When the user pulls the ring 18 and pulls the separator 16 connected to the other end of the wire 50, one end of the wire 50 is released from the rotation shaft 22, do. At this time, the direction in which the rotation shaft 22 rotates is the winding direction of the spring 20. Therefore, elastic energy is generated in the spring 20, and when the user releases the ring 18, the spring 24 is rotated to generate vibration.

As described above, according to the embodiment of the present invention, since the spring 20 is applied instead of the electric device as the structure for generating vibration, the production cost can be reduced, the weight can be reduced, and the size can be reduced. In addition, since the spring 20 having a semi-permanent lifetime is applied, the lifetime limitation can be overcome. Furthermore, the oscillation by the spring 20 is generated for a predetermined time according to the winding amount of the spring 20, so that the timer function can be naturally realized.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, And all changes to the scope that are deemed to be valid.
