Description

  The present invention relates to a structure of a vibration generator that generates vibration using a motor as a drive source.

  Conventionally, as a vibration generator that generates vibration using a motor as a drive source, the following publication is disclosed as a known technique.

JP 2003-189937 A JP-A-9-173151

  Each of the above publications has a structure for attaching an electronic component for generating vibration in the holder. In other words, the structure is such that a motor that generates vibration and a switch that controls the rotation of the motor are attached to the holder. In this case, by arranging the switch and the motor close to each other, a member to be connected, for example, a wire can be made to have a minimum length. The switch can rotate and stop the motor by detecting the operation of the operation button that is actually operated by the user such as pressing. Therefore, the operation button is often provided in the vicinity of the switch in a case serving as a casing of the vibration generator.

  By the way, depending on the vibration generator, it may be considered that the motor and the switch are attached at positions separated from each other. For example, this is a case where an operation button is provided at the end of the case. In this case, the switch is mounted at a position away from the motor by disposing the switch in the vicinity of the operation button provided at the end of the case. Then, since it is necessary to lengthen the wire connecting the motor and the switch, not only the cost is increased, but the structure of the holder can be obtained by providing a holder for holding the wire in the holder housed in the case. It becomes complicated. In addition, there is a concern that the assembly work of the vibration generator is affected by the necessity of wire connection processing with respect to the holder.

  Further, when a battery is used as a means for supplying electric power to the motor, the battery is generally attached to a holder, and a part of the case is generally detachable so that the battery can be replaced. If an operation button is provided at the end of the case and a switch is disposed in the vicinity of the operation button, the switch and the wire connecting the switch and the motor are exposed when the battery is replaced. For this reason, there is a high risk that the user accidentally touches the switch or the wire, causing failure or destruction of the vibration generator.

  The present invention has been made in view of the above-described points, and the object of the present invention is to simplify even if the switch for controlling the rotation of the motor and the operation button that the user actually operates are located at a distance. Another object of the present invention is to provide a vibration generating device that can detect the operation of the operation button while the switch is arranged near the motor.

  Another object of the present invention is to provide a vibration generator that does not expose electronic components such as a motor and a switch when the battery is replaced when a battery is used as means for supplying power to the motor. .

The vibration generator according to claim 1 is a vibration generator that includes a case top and a case bottom, a holder that is stored in a storage space for the case top and the case bottom, and a motor and a switch that are attached to the holder. The holder has a case top region surrounded by the case top and a case bottom region surrounded by the case bottom, and at least a motor and a switch are attached to the case top region, and an operation button is provided on the case bottom. And a structure in which a pressing piece is formed integrally with the operation button, and the movement of the pressing piece interlocked with the operation of the operation button is detected by the switch.

The vibration generating device according to claim 2 is the vibration generating device according to claim 1 , wherein a guide rib for restricting a moving direction of the pressing piece interlocked with the pressing operation of the operation button is provided on the inner surface side of the case bottom. It is characterized by having formed.

The vibration generating device according to claim 3 is the vibration generating device according to any one of claim 1 or claim 2 , wherein a rib is provided to extend from an opening of a storage space of the case bottom, and the rib In the peripheral direction, a locking hole and a guide groove on the inner surface side of the rib and connected to the locking hole are formed, and the holder is transmitted through the guide groove by rotating the case bottom. Thus, a protruding portion that is locked in the locking hole is formed.

A vibration generator according to a fourth aspect is the vibration generator according to any one of the first to third aspects, wherein the operation button is biased against a pressing force applied to the operation button. And is held against the case bottom via an elastic member for preventing water from entering the storage space of the case bottom.

  According to the structure of the present invention as described above, the motor and the switch are attached to the case top region of the holder surrounded by the case top, and the switch is pressed by the pressing piece formed on the operation button attached to the case bottom. Yes. As a result, since a switch can be arranged in the vicinity of the motor, the number of members necessary for connecting the motor and the switch can be minimized, the vibration generator can be realized with a simple structure, and the assembly work is also performed. It becomes easy. In addition, when using, for example, a wire rod as a member for connecting the motor and the switch in the present invention, it is not necessary to lengthen the wire rod more than necessary because the switch can be disposed in the vicinity of the motor.

  In addition, by mounting the motor or switch on the case top region of the holder and mounting the battery on the case bottom region of the holder, the motor or switch enclosed in the case top storage space can be externally replaced when replacing the battery. Therefore, it is possible to reduce the cause of failure or destruction of the vibration generator caused by the user touching the electronic component.

  11A and 11B are views showing a holder alone in the embodiment of the present invention. FIG. 11A is a plan view of the holder alone, and FIG. 11B is a side view thereof. As shown in the figure, the holder 4 has a case top region 4 e surrounded by the case top 2 and a case bottom region 4 f surrounded by the case bottom 3.

  In the case top region 4e, at least a motor attachment portion 4g and a substrate attachment portion 4h are formed. A motor 5 having an eccentric member attached to the rotating shaft is attached to the motor attachment portion 4g. A substrate 6 provided with a switch 6a for controlling the rotation of the motor 5 is attached to the substrate attaching portion 4h. That is, the implementation structure of the present invention collects at least electronic components necessary for generating vibration in the case top region 4 e of the holder 4. And after inserting the case top area | region 4e of the said holder 4 in the 1st storage space 2a of the said case top 2, it is set as the structure where the said case top 2 does not remove | deviate from the said holder 4 easily.

  Specifically, on the back side of the first storage space 2a formed on the case top 2, the locking pieces 4c and 4c formed on the holder 4 are moved to the case by the elastic force of the flexible portions 4b and 4b. The top 2 has a structure that is locked in locking grooves 2c and 2c formed in the first storage space 2a. In addition, the above-mentioned "back side" shows a position when it sees from the side which inserts the holder 4 in the 1st storage space 2a of the case top 2. As shown in FIG. As a result, for example, it is possible to prevent dangerous actions such as a user accidentally removing the holder 4 from the case top 2 and contacting an electronic component attached to the case top region 4e.

  In the embodiment of the present invention, a battery attachment portion 4 i for attaching a battery for supplying electric power to the motor 5 is formed in the case bottom region 4 f of the holder 4. The case bottom 3 attached so as to surround the case bottom region 4f has a structure that can be easily engaged / released by rotating with respect to the holder 4.

  Specifically, first, the case bottom 3 is moved to the case top 2 side so that the case bottom region 4f of the holder 4 to which the case top 2 is attached fits in the second storage space 3a of the case bottom 3. Let Then, the case bottom 3 is rotated at a position where the case bottom region 4 f of the holder 4 is accommodated in the second storage space 3 a of the case bottom 3. If the case bottom 3 is rotated with respect to the case top 2 attached to the holder 4, the engagement protrusions 4 d and 4 d formed on the holder 4 extend along the guide grooves 3 d and 3 d formed on the case bottom 3. The case bottom 3 can be attached to the holder 4 by the engagement protrusions 4d, 4d engaging with the engagement holes 3c, 3c. If the case bottom 3 is rotated in the direction opposite to the above from the state in which the case bottom 3 is attached to the holder 4, the engagement protrusions 4d and 4d are inserted from the engagement holes 3c and 3c. The case bottom 3 can be easily removed from the holder 4. As a result, the battery replacement operation for rotating the motor 5 is facilitated.

  In the embodiment of the present invention, a vibration generator using a battery that needs to be replaced according to the life of power is described. However, the present invention is not limited to the above-described structure, and includes, for example, a vibration generator that incorporates a battery that can maintain power by charging. If it is a vibration generating device incorporating a rechargeable battery, it is not necessary to remove the case bottom 3 and replace the battery as shown in the embodiment of the present invention. Therefore, the arrangement configuration including the electronic components attached to the holder 4 can be changed. As mentioned above, it is mentioned that various modifications are possible within the scope of the present invention.

  Next, a structure for detecting the operation of the operation button with a switch will be described. FIG. 12 is a side view showing a holder and operation buttons in the embodiment of the present invention. As shown in the figure, a substrate 6 on which a switch 6 a is disposed is attached to the case top region 4 e of the holder 4. An operation button 8 that is actually operated by the user is attached via an elastic member 9 to the end of the case bottom 3 opposite to the opening. In the embodiment of the present invention, the switch 6a detects that the operation button 8 exposed from the end of the case bottom 3 has been pressed, and the motor 5 is rotated to generate vibration. The elastic member 9 mainly serves to prevent water and foreign matter from entering the second storage space 3a of the case bottom 3, and the operation button 8 is operated by using the elastic force of the operation button 8 that has been pressed. It plays a role of returning to the state before being pressed. Further, in the vibration generator shown in the embodiment of the present invention, when the operation button 8 attached with the elastic member 9 is attached to the case bottom 3, the vibration generator can be installed from the opening side of the case bottom 3 or the case bottom 3. It is structured to be attached from the end side.

  The operation button 8 is formed with a step portion 8b for attaching the elastic member 9. Further, the operating button 8 is formed with a pressing piece 8c that directly presses the switch 6a when the operating button 8 is pressed against the elastic force of the elastic member 9. Guide ribs 3e and 3e are formed in the vicinity of the opening of the case bottom 3 and on the inner surface of the second storage space 3a for guiding the pressing piece 8c that moves by the pressing operation of the operation button 8 to the switch 6a. (See FIG. 6).

  With the above-described structure, the pressing piece 8c that moves along the guide ribs 3e and 3e by the pressing operation of the operation button 8 can surely press the switch 6a disposed on the substrate 6. The movement of the pressing piece 8c is detected by the switch 6a, and the rotation of the motor 5 is controlled. The pressed operation button 8 moves to a position before pressing away from the switch 6a by the restoring force of the elastic member 9 when the load is removed.

  Further, when replacing the battery, it is conceivable that the case top 3 in a state where the user presses the operation button 8 is attached to the holder 4 attached to the case top 2. In this case, since it is assumed that the pressing piece 8c damages the switch 6a, it is preferable to form a wall portion (not shown) in the holder 4 that prevents the switch 6a from being damaged. By forming the wall portion, when the case bottom 3 is attached, the pressing piece 8a can be attached to the holder 4 in a state where it is stopped at the position before the pressing of the operation button 8 separated from the switch 6a. Become. The shape of the wall portion is not particularly limited, and a shape that does not hinder the attachment / detachment of the case bottom 3 to the holder 4 may be selected as appropriate.

  As described above, in the embodiment of the present invention, the vibration generating device provided with the operation button 8 at the end of the case bottom has been described. However, the present invention is not limited to the above-described structure, and for example, a part for pressing the switch 6 a instead of the operation button 8 may be provided on the peripheral portion of the case bottom 3. Moreover, the Example of this invention has demonstrated the vibration generator using the switch 6a which detects pressing with the press piece 8. FIG. However, the present invention is not limited to the above-described structure. For example, a non-contact type switch, a contact type switch, or a switch using another switching method may be used. That is, the present invention relates to a vibration generator provided with an operation button that is actually operated by a user at a position away from a switch that controls rotation of a motor. Therefore, the arrangement configuration including electronic parts can be changed without being limited to the embodiment of the present invention. As mentioned above, it is mentioned that various modifications are possible within the scope of the present invention.

  By the way, according to the structure shown in the embodiment of the present invention, the switch 6a of the substrate 6 attached to the case top region 4e of the holder 4 and the pressing piece 8c of the operation button 8 attached to the end of the case bottom 3 are provided. The positional relationship is important. That is, the switch 6a of the substrate 6 attached to the case top region 4e of the holder 4 can be surely pressed by the pressing piece 8c provided on the case bottom 3 that can be easily attached / released for battery replacement. Therefore, it is necessary to make the positional relationship when the case bottom 3 is attached to the case bottom region 4f of the holder 4 constant.

  Next, a structure for making the positional relationship when the case bottom 3 is attached to the holder 4 constant will be described. FIG. 13 shows a case bottom in the embodiment of the present invention, and is a view when the opening is viewed from the front side. As shown in the figure, a position regulating rib 3f is formed in the vicinity of the opening of the case bottom 3 and on the inner surface of the second storage space 3a in parallel with the aforementioned guide ribs 3e, 3e.

  FIG. 14 is a view showing the vicinity of the battery mounting portion of the holder in the embodiment of the present invention, FIG. 14 (a) is a bottom plan view of the battery mounting portion, and FIG. 14 (b) is an end face side of the battery mounting portion. FIG. As shown in the figure, the case bottom region 4f of the holder 4 is formed with a contact protrusion 4j that enables the position regulating rib 3f formed on the case bottom 3 to contact. The case bottom region 4f is formed with a retracting surface 4k so that the guide ribs 3e, 3e and the pressing piece 8c do not come into contact when the case bottom 3 is attached to the holder 4. In the embodiment of the present invention, the contact protrusion 4j and the retracting surface 4k are formed on the bottom surface side of the battery mounting portion 4i.

  The contact protrusion 4j extends from the end of the battery mounting portion 4i to a certain length and is not formed over the entire length of the battery mounting portion 4i. In the embodiment of the present invention, when the case bottom 3 is attached to the holder 4, the case bottom 3 is rotated at a position where the case bottom region 4 f of the holder 4 is accommodated in the second storage space 3 a of the case bottom 3. Therefore, when the case bottom 3 is rotated, the position restricting rib 3f is formed so as not to contact the contact protrusion 4j. Note that the end of the battery mounting portion 4i formed on the holder 4 is partially cut out from a circular shape by providing the contact protrusion 4j and the retracting surface 4k.

  With the above-described structure, when the case bottom 3 is attached from the end of the battery mounting portion 4i having a different shape, the position regulating rib 3f formed on the case bottom 3 and the contact protrusion 4j formed on the holder 4, and The position is regulated by the guide rib 3 e formed on the case bottom 3 and the retracting surface 4 k formed on the holder 4. The case bottom attached to the holder 4 can be securely attached at a position where the switch 6a can be pressed by the pressing piece 8c.

  More specifically, when the case bottom region 4f of the holder 4 is inserted into the second storage space 3a of the case bottom 3, the holder 4 is formed with the position regulating rib 3f formed on the case bottom 3. The rotation of the case bottom 3 in one direction is restricted by the contact protrusion 4j. Further, the rotation of the case bottom in the other direction is restricted by the guide rib 3 e formed on the case bottom 3 and the retracting surface 4 k formed on the holder 4. In the position where the case bottom region 4f of the holder 4 is accommodated in the second storage space 3a of the case bottom 3, the position regulating rib 3f and the contact protrusion 4j are formed so as not to contact each other. Therefore, the case bottom 3 can be rotated and attached.

  As described above, in the embodiment of the present invention, as a means for making the positional relationship when the case bottom 3 is attached to the holder 4 constant, the rotation direction is regulated by the position regulating rib 3f and the contact protrusion 4j, and the guide rib 3e and the retracting surface 4k. The vibration generating device provided with the above is described. However, the present invention is not limited to the above-described structure. For example, a plurality of position restricting ribs 3f may be formed, or a groove in which the guide rib 3e can slide instead of the contact protrusion 4j may be provided. That is, the present invention relates to a vibration generator provided with an operation button that is actually operated by a user at a position away from a switch that controls rotation of a motor. Therefore, it is mentioned that various modifications can be made within the scope of the present invention without limiting to the embodiment of the present invention as means for making the positional relationship between the switch and the operation button constant.

  Next, a method of using the vibration generator shown in the embodiment of the present invention will be described. FIG. 15 is a perspective view showing a toothbrush body and a case top. As shown in the figure, an attaching / detaching portion 2 d is provided at the end of the case top 2. The toothbrush body 11 can be attached to and detached from the attaching / detaching portion 2d. By the way, in the Example of this invention, the handle | pattern of the said toothbrush body 11 is formed with transparent resin. An LED (light emitting diode) 6b is disposed on the substrate 6 stored in the first storage space 2a of the case top 2. That is, in the embodiment of the present invention, the rotation control of the motor 5 and the light emission control of the LED 6b are performed by the pressing operation of the operation button 8.

  Here, the structure in the vicinity of the LED 6b will be described in detail. The board 6 is provided with an LED 6b together with the switch 6a. A lens (not shown) for guiding the light of the LED 6b to the toothbrush body 11 is attached to the attaching / detaching portion 2d side of the case top 2.

  In the embodiment of the present invention, the rotation of the motor 5 and the light emission of the LED 6b are controlled by the number of times the operation button 8 is pressed. Specifically, if the first pressing of the operation button 8 is detected by the switch 6a, the LED 6b emits light. That is, the toothbrush body 11 attached to the vibration generator 1 is in a light emitting state. If the second pressing operation of the operation button 8 is detected by the switch 6a, the motor 5 rotates with the LED 6b emitting light. That is, the toothbrush body 11 attached to the vibration generator 1 is in a state of generating vibration while emitting light. Further, if the third pressing operation of the operation button 8 is detected by the switch 6a, the light emission of the LED 6b and the rotation of the motor 5 are stopped. That is, the light emission and vibration of the toothbrush body 11 attached to the vibration generator 1 are stopped.

  As mentioned above, the Example of this invention demonstrated the vibration generator 1 which attached the toothbrush body 11. FIG. However, the present invention is not limited to the above-described structure. For example, in addition to a toothbrush, an ear or nail cleaning device or a massage device such as a face or shoulder may be attached. That is, the present invention can be applied within the scope of the gist of the present invention as long as it uses a vibration generator that mainly converts the rotation of the motor into vibration. The present invention also includes a structure in which a light emitting function is added to the vibration generator described above.
