JP 2003-93415 A

  Usually, it is optimal to replace the toothbrush in about two weeks. However, since it is a brush portion with a handle that can be replaced in a conventional electric toothbrush, the cost of the replacement brush is increased and cannot be easily replaced. However, in the electric toothbrush in which the replaceable brush unit 3 shown in FIG. 11 can be attached and detached, the replaceable brush unit 3 can be provided at a low cost, so that easy replacement can be promoted, and the brushing effect without bending of the brush hair can be maintained.

  However, although it is easy to replace with the replacement brush unit 3, since it is left to the user to determine whether or not to replace, the replacement time often passes and the sustainability of the toothpaste effect is impaired. Invite.

  Therefore, in view of the above problems, an object of the present invention is to provide an electric toothbrush that can inform the user of the timing of toothbrush replacement.

  The invention according to claim 1 is an electric toothbrush having a battery housing part in a gripping part, using a built-in motor as a driving source for toothbrush vibration, and having a start / stop switch for the motor. The power supply detection means for detecting the power supply energization by the battery to be loaded and the notification means for outputting the battery loading notification information based on the power supply detection information of the power supply detection means.

  When a battery is loaded in the battery compartment, if the polarity is correct, the power detection means outputs power detection information by power activation, and the notification means outputs battery loading notification information, but the battery polarity is incorrect Since the power supply detection means is not energized and is not responding, the notification means does not output the battery loading notification information, so the user can notice the erroneous loading of the electric toothbrush and perform the battery loading again. be able to.

  In this electric toothbrush, when the start / stop switch is operated after the battery loading notification information is output, the output of the battery loading notification information is stopped.

  According to a third aspect of the present invention, the brush part is replaceable, has a battery that is normally loaded in the handle part, has a built-in motor as a driving source for toothbrush vibration, and includes a start / stop switch for the motor. A timing unit for accumulating the driving period of the motor that is activated at each activation operation of the activation / stop switch, and a time limit for determining whether or not the accumulated driving time of the timing unit exceeds a predetermined time It has a determination means and a notification means for outputting toothbrush replacement notification information when a predetermined time is exceeded.

  In such an invention, since the time measuring means for accumulating the driving period of the motor that is started every time the start / stop switch is started is provided, the cumulative driving period of the motor, that is, the total tooth brushing time can be measured. When the period exceeds a predetermined time, toothbrush replacement notification information is output from the notification means. For this reason, since the user can know the replacement time of the toothbrush portion and perform the replacement, the brushing effect can be maintained.

  The invention according to claim 4 is an electric toothbrush having a battery that is normally loaded in the gripping part, having a built-in motor as a driving source for toothbrush vibration, and having a start / stop switch for the motor. -In the drive period of the said motor started by start operation of a stop switch, it has a notification means which outputs brush position change notification information for every fixed time period.

  In such an invention, since the notification means for outputting the brush position change notification information is provided at regular time intervals during the drive period of the motor that is activated by the activation operation of the activation / deactivation switch, the user can maintain a certain amount during brushing. Since it is possible to know the brushing time for each brush position from the brush position change notification information output for each time period, it is possible to encourage brushing for each brush position.

  The invention according to claim 5 is an electric toothbrush having a battery that is normally loaded in the gripping part, having a built-in motor as a driving source for toothbrush vibration, and having a start / stop switch for the motor. Start control means for controlling the motor to a low speed rotation triggered by a start operation of a stop switch; and a control for switching the motor to a high speed rotation triggered by a switching operation of the start / stop switch during the low speed rotation of the motor. 1 switching control means, 2nd switching control means for switching the motor to low speed rotation when the start / stop switch is switched during high speed rotation of the motor, and stop operation of the start / stop switch And a stop control means for stopping the rotation of the motor.

  In such an invention, when a start operation is performed such that the start / stop switch is pressed in the motor stop state, the start control means causes the motor to rotate at a low speed, and during this low speed rotation, the start / stop switch is momentarily pressed. When the switching operation is performed, the motor is switched to the high speed rotation by the first switching control means. During this high speed rotation, when the switching operation such as momentary pressing is performed on the start / stop switch, the second switching control means The motor switches to low speed. In addition, when a stop operation such as a long press is performed on the start / stop switch while the motor is rotating at a low speed or a high speed, the rotation of the motor is stopped by the stop control means. The motor can be stopped by switching the speed of the motor and the stopping operation such as long pressing by switching operation such as momentary pressing with respect to one start / stop switch, and the electric toothbrush can be made compact by reducing the number of switches. In addition, brushing adjustment can be adjusted by switching between low speed and high speed.

  In the present invention, it is desirable to provide a motor forward / reverse rotation switching switch. Since the toothbrush vibration method can be reversed by the switching operation on the forward / reverse rotation changeover switch, the scraping direction of tartar or the like can be appropriately changed.

  The invention according to claim 7 is an electric toothbrush having a battery that is normally loaded in the gripping part, having a built-in motor as a driving source of toothbrush vibration, and having a start / stop switch for the motor, Start control means for controlling the motor to rotate in the forward direction upon the start operation of the stop switch; and a control for switching the motor to the reverse rotation in response to the switching operation of the start / stop switch during the forward rotation of the motor. 1 switching control means, 2nd switching control means for switching and controlling the motor to normal rotation upon the switching operation of the start / stop switch during reverse rotation of the motor, and the stop operation of the start / stop switch And a stop control means for stopping the rotation of the motor.

  In such an invention, when a start operation is performed such that the start / stop switch is pressed while the motor is stopped, the motor is normally rotated by the start control means. During this normal rotation, the start / stop switch is momentarily pressed. When the switching operation is performed, the motor is switched to reverse rotation by the first switching control means. During this reverse rotation, when the switching operation such as momentary pressing is performed on the start / stop switch, the second switching control means The motor switches to normal rotation. In addition, when a stop operation such as a long press is performed on the start / stop switch while the motor is rotating forward or backward, the stop control means stops the rotation of the motor. The motor can be stopped by switching the rotation direction of the motor and the stopping operation such as long pressing by switching operation such as momentary pressing for one start / stop switch, and the electric toothbrush can be made compact by reducing the number of switches. Also, the scraping direction of tartar or the like can be changed as appropriate by switching between forward rotation and reverse rotation.

  In the present invention, it is desirable to provide a low-speed / high-speed rotation switch for the motor. Since the frequency of the toothbrush can be changed by the switching operation for the low-speed / high-speed rotation switch, the brushing can be changed.

  The invention according to claim 9 is an electric toothbrush in which the brush part is replaceable, has a battery that is normally loaded in the gripping part, and has a built-in motor from the gripping part toward the handle part that communicates with the toothbrush part. And it has an electrical conductor which covers the outer periphery of the said holding part at least, It is characterized by the above-mentioned.

  In such an invention, since at least a part of the motor is covered with a conductor, electromagnetic noise generated by the motor is absorbed from the conductor through the human body when the grip portion of the electric toothbrush is gripped by hand. Therefore, the emission of electromagnetic noise that affects peripheral devices can be suppressed, and in particular, a low-cost motor that does not include a spark extinguishing element such as a varistor can be used.

  In the present invention, since a timing means for accumulating the driving period of the motor that is activated every time the activation operation of the activation / deactivation switch is provided, the total tooth brushing time can be counted, so when the accumulated driving period exceeds a predetermined time, an announcement is made. Toothbrush replacement notification information is output from the means. For this reason, since the user can know the replacement time of the toothbrush portion, the toothbrushing effect can be maintained by replacing the toothbrush portion.

  Next, embodiments of the present invention will be described with reference to the accompanying drawings.

  1 is a sectional view showing an electric toothbrush according to a first embodiment of the present invention, FIG. 2 (a) is a front view showing a control board used in the electric toothbrush, and FIG. 2 (b) is a plan view showing the control board. FIG. 3 is a circuit diagram showing an electrical configuration of the electric toothbrush.

  The electric toothbrush of this example includes a toothbrush body 10 shown in FIG. 1 and a replacement brush unit 3 shown in FIG. The toothbrush main body 10 includes a grip portion 11, a handle portion 1 extending from one end thereof, and a head portion 2 that is a tip of the handle portion 1, and is integrally formed of resin. The head unit 2 has a structure shown in FIG.

A battery accommodating portion 11a for accommodating _two batteries (AAA dry batteries) B ₁ and B ₂ is provided in the grip portion 11, and the battery accommodating portion 11a is closed by an end lid 11b having a presser spring S. Positive electrode on the back side cell B ₁ represents contact with the positive terminal piece 11c, the minus electrode of the front battery B ₂ is pressed against the pressing spring S of the end cap 11b. A motor housing portion 11d for housing a vibration motor M having an eccentric weight W is formed from the battery housing portion 11a to the handle portion 1 side. The motor housing portion 11d is a cavity having a smaller diameter than the battery housing portion 11a, and the eccentric weight W of the vibration motor M is located on the back side of the motor housing portion 11d (tapered portion 1a connected to the handle portion 1). A cylindrical bracket B as a spacer is externally fitted to the body portion of M and is fitted in the motor storage portion 11d. For this reason, even when the diameter of the trunk portion of the motor M is smaller than the locus circle of the eccentric weight W, the eccentric weight W does not contact the inner peripheral surface of the motor storage portion 11d.

The anti-eccentric weight side end of the vibration motor M is prevented from coming off by a plus terminal piece 11c, and two power supply lines L ₁ and L ₂ are drawn from the anti-eccentric weight side end. A control board 11e is fitted in the board frame part F provided on the outer peripheral surface of the gripping part 11 near the tapered part 1a. One end of the plus terminal piece 11c is inserted into and connected to the control board 11e. As shown in FIG. 2, notches H _{1 to} H ₃ are formed at the edge of the control board 11e. Feed lines L ₁ and L ₂ from the vibration motor M are connected to the control board 11e through the cuts H ₁ and H ₂ . The lead wire L ₃ connecting the presser spring S is wired along the inner circumferential surface of the battery housing section 11a, is connected to the control board 11e through incisions H _3. For this reason, even if the control board 11e is fitted in the board frame portion, the power supply lines L ₁ and L ₂ and the lead wire L ₃ can be drawn out and connected to the upper surface side of the control board 11e. The control board 11e has the microcomputer A as a main component, and has a first push button switch SW1, a second push button switch SW2, and a notification buzzer BZ.

  The vibration motor M is a small motor with a brush, and has a brush pair (not shown) at the end of the body on the side opposite to the eccentric weight, and the end on the side opposite to the eccentric weight of the motor M is in the battery housing portion 11d. To position. The outer periphery of the gripping part 11 is covered with an aluminum conductive tube 11g except for a part of the substrate frame part F, and the anti-eccentric weight side end (brush pair) of the motor M is also substantially covered. In the state where the grip portion 11 of the electric toothbrush main body 10 is gripped by hand, electromagnetic noise generated by the vibration motor M is absorbed from the conductive tube 11g through the human body, and therefore, electromagnetic noise radiation that affects peripheral devices is emitted. Can be suppressed. In particular, a low-cost motor M that does not include a spark extinguishing element such as a varistor can be used.

  Hereinafter, operation | movement of the electric toothbrush of this example is demonstrated based on the flowchart of FIGS. The electric toothbrush of this example is a two-push button system (SW1, SW2), but has a function of detecting whether the battery is loaded correctly.

In step ST1 of FIG. 4, when the two batteries B ₁ and B ₂ are loaded in the battery storage portion 11a, the microcomputer A functions as a power source detection means for determining whether or not the power is energized. When normal insertion is performed in step ST2, a motor stop command is first output in step ST3. This motor stop command is to set both the forward rotation command and the reverse rotation command of the vibration motor M to the ground potential (0 V) in FIG. 3, the transistors Q2 and Q4 are turned off, the transistors Q1 and Q3 are turned on, and the vibration is stopped. Since the power supply voltage Vcc is supplied to the power supply lines L1 and L2 of the motor M, the vibration motor M does not rotate.

This motor stop command also functions as power supply detection information, outputs a battery loading notification command for turning on the transistor Q6 in step ST4, and the notification buzzer BZ generates a ringing pattern. The ringing pattern is a repetition of the silent period T ₂ of the sounding period T ₁ and an OFF state of the intermittent ON. By this ringing pattern, the user can know that the battery is loaded normally.

  On the other hand, if this ringing pattern is not heard, it can be known that the battery has been inserted abnormally, so the user tries to remove the battery and reload it in step ST5.

  Since the ringing pattern of step ST4 continues for a long time, it is determined in step ST6 whether the push button switch (start / stop switch) SW1 is pressed (turned on). When not pressed, the ringing pattern continues, but when pressed, the ringing of the notification buzzer BZ is stopped by turning off the transistor Q6 in step ST7. The steps up to this point are a group of steps for detecting and notifying whether or not the battery is loaded correctly, but the 30-minute counter is cleared to 0 in step ST8. As will be described later, the 30-minute counter accumulates the drive time of the vibration motor M to notify the replacement time of the replacement brush unit 3.

  In step ST9, in order to reduce the power consumption of the microcomputer A, the operation of the microcomputer A enters the sleep mode.

  Next, an operation mode according to the operation of the first push button switch (start / stop switch) SW1 and the second push button switch (forward / reverse switch) SW2 will be described with reference to FIG.

  In step T1, it is determined whether or not the first push button switch SW1 has been pressed. If it is not pressed, the determination is repeated until it is pressed, but if it is pressed, the operation of the microcomputer A is released from the pause mode in step T2, returns to the normal mode, and in step T3, 5 for fixed position brushing is performed. After counting the second counter is started and the time counting of the 2-minute counter for brushing once is started in step 4, a normal motor low-speed rotation command is output in step T5. This forward rotation motor low-speed rotation command is a ground potential reverse rotation command for turning on the transistor Q1 in FIG. 3 and a Vcc potential forward rotation command for turning on the transistor Q4, and the vibration motor M has a low polarity shown in FIG. Since a voltage (a voltage obtained by subtracting the voltage between the emitter and the collector of the transistor Q1 and the voltage between the collector and the ground of the transistor Q4) from the Vcc voltage is applied, the vibration motor M first rotates at a normal speed and at a low speed. This allows the user to start brushing his teeth.

  In the low-speed forward rotation state of the vibration motor M, it is determined in step T6 whether or not the first push button switch SW1 has been pressed. If the switch SW1 has not been pressed, it is determined in step T7 whether or not the second push button switch SW2 has been pressed. If the switch SW2 is not pressed, the home position brushing operation routine is executed in step T8 as described later.

  When the first push button switch SW1 is pressed in step T6, it is determined in step T9 whether the press is a long press (1 second or more) or an instantaneous press (1 second or less). In this case, a motor stop command is first output in step T17. The motor stop command is that both the forward rotation command and the reverse rotation command of the vibration motor in FIG. 3 are set to the ground potential (0 V), the transistors Q2 and Q4 are turned off, the transistors Q1 and Q3 are turned on, and the vibration motor Since the power supply voltage Vcc is supplied to both of the M power supply lines L1 and L2, the vibration motor M does not rotate.

  If it is instantaneously pressed in step T9, it is determined in step T10 whether the motor is rotating at a low speed or in a high speed. If it is rotating at a low speed, a motor high speed rotation command is output in step 11. This motor high-speed rotation command is a low-speed / high-speed rotation command for the power supply potential Vcc. In FIG. 3, the transistor Q5 is turned on, and the voltage between the emitter and collector of the transistor Q5 is lower than the voltage drop of the diode D2. As a result, the voltage applied to the vibration motor M increases, and the vibration motor M rotates at high speed. On the other hand, if the motor is rotating at a high speed in step T10, a motor low speed rotation command is output in step 12. This motor low-speed rotation command is a ground / low-speed rotation command. In FIG. 3, the transistor Q5 is turned off and the voltage drop of the diode D2 is higher than the emitter-collector voltage of the transistor Q5. The applied voltage is lowered, and the vibration motor M rotates at a low speed.

  As described above, when the first push button switch SW1 is first pressed, the vibration motor M rotates at a low speed in the normal direction, when the switch SW1 is pressed and held for a long time, the vibration motor M rotates at a low speed in the normal direction. Switches to high speed rotation, and switches to low speed rotation during high speed rotation. For this reason, it is possible to select the level of brushing (strength) by switching between high and low. Since the difference between the long press and the short press of the switch SW is determined, the switch SW functions not only as a switch for starting / stopping but also as a switch for switching between high and low, and contributes to a reduction in the number of switches.

  If the second push button switch SW2 is pressed in step T7, it is determined in step T13 whether the motor rotation direction is forward rotation or reverse rotation. If the motor rotation direction is normal rotation, a motor reverse rotation command is output in step T14. This motor reverse rotation command is a reverse command of the power supply potential Vcc for turning on the transistor Q2 in FIG. 3 and a normal rotation command for the ground potential for turning on the transistor Q3. The voltage applied by the vibration motor M has the polarity shown in FIG. Is reversed, and the vibration motor M rotates in the reverse direction. On the other hand, if the motor rotation direction is reverse in step T13, a motor forward rotation command is output in step 15. The motor forward rotation command is a forward rotation command of the power supply potential Vcc for turning on the transistor Q4 in FIG. 3 and a reverse rotation command of the ground potential for turning on the transistor Q1, and the voltage applied by the vibration motor M has the polarity shown in FIG. Therefore, the vibration motor M rotates forward.

  Thus, every time the second push button switch SW2 is pressed, the motor rotation direction is switched, and the rotation direction of the eccentric weight W is switched. Therefore, the circular vibration direction of the handle 1 is switched, and the electric toothbrush is held with one hand. Even if it continues, since the sweeping direction of the toothbrush tip of the toothbrush with respect to the tooth surface can be reversed, for example, the sweeping direction can be selected for the right tooth row and the left tooth row, and the brushing effect can be enhanced.

  In the fixed position brushing operation routine in step T8, as shown in FIG. 6, it is first determined whether or not the motor is rotating in step U1, and if it is rotating, whether or not the 5-second counter has passed 5 seconds in step U2. Judging. If 5 seconds have not passed, it is determined in step U3 whether the 5 second counter has passed 4 seconds. If 4 seconds have passed, a buzzer sounding command is output in step U4 and the transistor Q6 is turned on. Then the notification buzzer BZ sounds. If the 5-second counter has elapsed in step U2, the buzzer stop command is output in step U5, the transistor Q6 is turned off to stop the ringing of the notification buzzer BZ, and then the 5-second counter is set in step U6. Clear to zero, and start counting the time of the 5-second counter in step U7.

  In step 16 of FIG. 5, it is determined whether or not the 2-minute counter has passed 2 minutes. If less than 2 minutes, the process returns to step T6. As described above, since the buzzer BZ sounds for 1 second for 5 seconds continuously while the motor is rotating, the user continues to brush the teeth with teeth in a fixed position for 5 seconds, and then is urged by the sound to push the hair. The tip can be moved to another tooth and fixed position brushing can be performed, and insufficient polishing or unpolished can be suppressed.

  If the 2-minute counter has elapsed for 2 minutes, a motor stop command is output in step T17 described above, and the rotation of the vibration motor M is automatically stopped. By driving the vibration motor M for 2 minutes, 24 times (= 120 ÷ 5) fixed position brushing sounding periods occur. In step 18, the buzzer of the ground potential that turns off the transistor Q6 is considered in consideration of the case where the vibration of the fixed position brushing is generated when the vibration motor M is stopped by the long press of the first push button switch SW1. Output a stop command.

In step T19, the driving period of the vibration motor M is accumulated by the 30-minute counter, and in step T20, it is determined whether or not the 30-minute counter has passed 30 minutes. In order to reduce power consumption, the microcomputer A is set to a sleep mode. On the other hand, when the 30-minute counter is 30 minutes or more, the buzzer sounding to urge replacement of the brush unit 3 is performed instead of step T21. The buzzer sounding pattern, the sounding period T ₁ and a silent period T ₂ of the long nonconductive than sounding period T ₁ Toko of T ₁ of the the silence period T ₁ and the intermittent conductive non-conducting intermittent conduction of transistor Q6 1 It is repeated several times as a tour. From this ringing pattern, the user can know when to replace the replacement brush unit 3. In step T23, the 30-minute counter is cleared to zero.

  In the above embodiment, the motor rotation level is switched by momentary pressing of the switch SW1 and the motor rotation direction is switched by operating the switch SW2. However, the motor rotation direction is switched by momentary pressing of the switch SW1. Instead, it can be configured such that the height of the motor is switched by the operation of the switch SW2.

  FIG. 7 is a sectional view showing an electric toothbrush according to the second embodiment of the present invention, and FIG. 8 is a circuit diagram showing an electrical configuration of the electric toothbrush.

  The toothbrush main body 20 of this example is a three-push button system, and the other configurations are the same as those of the electric toothbrush of the first embodiment, so the same reference numerals are given and the description thereof is omitted.

  In this example, the first push button switch SW1 is a start / stop switch, the second push button switch SW2 is a forward / reverse switch, and the third push button switch SW3 is a high / low switch.

  In step ST6 shown in FIG. 10, it is determined whether or not the first push button switch SW1 has been pressed. If pressed, the number of times of pressing is an even number, which corresponds to a stop operation. The motor stop command is output at, and the rotation of the vibration motor M stops.

  If the switch SW1 is not pressed in step T6, it is determined in step T7 whether or not the second push button switch SW2 is pressed. If the button is pressed, step 14 or step 15 is executed after the determination in step T13.

  If the switch SW2 is not pressed in step T7, it is determined whether or not the third push button switch SW3 is pressed in step T7 ′. If the button is pressed, step 11 or step 12 is executed after the determination in step 10. If it is not pressed in step T7 ', the process proceeds to step T8.

  Thus, an electric toothbrush can also be configured by a three-push button method.
