Description

The present invention relates to a toothbrush device.
This application claims priority based on Japanese Patent Application No. 2019-233342 filed in Japan on December 24, 2019, the contents of which are incorporated herein.

BACKGROUND ART Devices (for example, devices called smart toothbrushes) that evaluate tooth brushing based on sensed data and display the results of the evaluation have been known.
In order to evaluate tooth brushing, it is necessary to detect the brushing position. Directly detecting the brushing position requires image analysis using a camera, etc., and the device becomes large-scale. Therefore, the brushing position is generally estimated indirectly by detecting the angle of the toothbrush. Although the method of estimating the brushing position from the angle of the toothbrush is simple, there is a problem in that it is difficult to distinguish between left and right occlusal surfaces and between buccal and lingual sides.
To solve this problem, conventional methods have been used, such as mounting electrodes on the toothbrush head and determining the position based on the energization state, and providing a toothbrushing guide. The method of mounting electrodes on the toothbrush head makes the toothbrush head large and has poor operability. In one example of a method for providing a toothbrushing guide, by specifying the area to be brushed next using a display terminal such as a smartphone, it is possible to highly accurately estimate the brushing position based on the detected toothbrush angle and the specified area. be. However, in this example, the user must use a display terminal in addition to the toothbrush device, which increases the user's effort.

Furthermore, systems have been known that provide feedback to individuals based on their brushing performance and provide guidance regarding brushing for individuals (for example, see Patent Document 1). Patent Document 1 describes an oral hygiene device such as an electronic toothbrush that includes a toothbrush member, a sensor, a storage unit, and a communication circuit. The oral hygiene device described in Patent Document 1 is used by a user in combination with a user device such as a smartphone.
By the way, Patent Document 1 describes which part of the motion sensing data collected by the sensor (that is, the motion sensing data of which time period) should be used to determine (calculate) the user's oral hygiene cleaning performance. It has not been. Therefore, depending on the technique described in Patent Document 1, there is a possibility that the user's oral hygiene cleaning performance cannot be accurately determined (calculated).

Further, Patent Document 2 describes a technique for supporting appropriate use of an electric toothbrush and correct brushing. In the technique described in Patent Document 2, an acceleration sensor is installed on a toothbrush, the attitude of the toothbrush is obtained from the output of the acceleration sensor, and the brushing area is estimated based on the attitude of the brush. Further, a timer measures the brushing time of the brushing area. Furthermore, based on the measured brushing time, the brushing results for each part are evaluated and output.
In addition, Patent Document 2 states that since it is not appropriate to record and evaluate the brushing time and brush angle while the brush is moving between parts, posture detection and brushing part estimation are performed while no load is acting on the brush. , it is written that processes such as measuring brushing time, estimating brush angle, detecting brush pressure, and outputting brushing results are prohibited.
By the way, in the technique described in Patent Document 2, in order to determine which part of the acceleration data detected by the acceleration sensor (that is, which time period of acceleration data) should be used to evaluate brushing. , a load sensor is installed to detect brush pressure.
Therefore, the technology described in Patent Document 2 may increase costs.

<First embodiment>
FIG. 1 is a diagram showing an example of a schematic configuration of a toothbrush device 1 according to a first embodiment. In detail, FIG. 1(A) shows an example of a functional block of the toothbrush device 1 of the first embodiment, and FIG. 1(B) shows an example of the schematic configuration of the toothbrush device 1 of the first embodiment. There is.
In the example shown in FIG. 1 (specifically, the example shown in FIG. 1(B)), the toothbrush device 1 is an attachment attached to a toothbrush (not shown). The toothbrush device 1 includes a hole 1A into which a toothbrush handle (not shown) is inserted.
In other examples, the toothbrush device 1 may be built into a toothbrush.

In the example shown in FIG. 1 (specifically, the example shown in FIG. 1A), the toothbrush device 1 includes a detection section 11, a guide output section 12, a storage section 13, and an evaluation section 14. . The detection unit 11 detects a predetermined physical quantity related to tooth brushing behavior of a user of a toothbrush (not shown).
In the example shown in FIG. 1, the detection unit 11 includes an acceleration sensor (not shown). The detection unit 11 detects physical quantities (for example, inclination, frequency, amplitude, etc.) related to the toothbrushing behavior of the toothbrush user by using the acceleration detected by the acceleration sensor.
In another example, the detection unit 11 may include a gyro sensor (not shown). In this example, the detection unit 11 detects a physical quantity related to the toothbrushing behavior of the toothbrush user by using the angular velocity detected by the gyro sensor.
In still another example, the detection unit 11 may include a magnetic sensor (not shown). In this example, the detection unit 11 detects a physical quantity related to the toothbrushing behavior of the toothbrush user by using azimuth information obtained by the magnetic sensor.
In still other examples, the detection unit 11 may include any other sensor as described in Patent Document 2, for example.

In the example shown in FIG. 1 (specifically, the example shown in FIG. 1A), the guide output unit 12 outputs a toothbrushing guide GD that assists the toothbrush user's toothbrushing behavior. The storage unit 13 stores the physical quantity detected by the detection unit 11 while the guide output unit 12 is outputting the tooth brushing guide GD. The evaluation unit 14 evaluates the toothbrushing behavior of the toothbrush user based on the physical quantity detected by the detection unit 11 and stored in the storage unit 13 .
In the example shown in FIG. 1, the toothbrush device 1 is equipped with a mode in which the evaluation section 14 starts evaluating the toothbrushing behavior of the toothbrush user after the detection section 11 finishes detecting the physical quantity.
In another example, the toothbrush device 1 may include, in addition to this mode, a mode in which the evaluation unit 14 starts evaluating the toothbrushing behavior of the toothbrush user before the detection unit 11 finishes detecting the physical quantity. good.

FIG. 2 is a diagram showing an example of a tooth brushing guide GD outputted by the guide output section 12. Specifically, FIG. 2(A) shows a first part GD1 and a second part GD2 included in the tooth brushing guide GD output by the guide output unit 12. FIG. 2(B) shows the design data number N, which is the number of designed physical quantity data to be detected by the detection unit 11 during the period (time tS to time tE) during which the tooth brushing guide GD is outputted by the guide output unit 12. etc.
In the example shown in FIGS. 1 and 2, the guide output section 12 includes a speaker. The guide output unit 12 outputs audio as a toothbrushing guide GD that assists the toothbrushing action of the toothbrush user. That is, in the example shown in FIGS. 1 and 2, the tooth brushing guide GD is an auditory guide. The toothbrushing guide GD includes a first part GD1 that indicates the area to be brushed, and a second part GD2 that is an indicator of the period in which the teeth should be brushed.
The guide output unit 12 outputs, as the first part GD1 of the toothbrushing guide GD, a voice saying, for example, "Let's start brushing! Let's try it on your mouth! Brush your front teeth!". As a result, even if the toothbrush user is an infant, the toothbrush user can easily understand that the area to be brushed is the buccal side (labial side) of the front teeth.
Next, the guide output unit 12 outputs, for example, the sound of "shakashaka, shakashaka, shakashaka, shakashaka, shakashaka" as the second part GD2 of the toothbrushing guide GD. As a result, even if the user of the toothbrush is an infant, the user of the toothbrush can easily understand that the period during which the second part GD2 is output is the period during which tooth brushing should be performed. .

In other examples, the guide output unit 12 may output audio other than the above-mentioned audio as the first part GD1, and the guide output unit 12 may output audio other than the above-mentioned audio as the second part GD2. Good too.
In yet another example, the guide output section 12 may include a vibration generator (not shown). In this example, the guide output unit 12 outputs vibration as a toothbrushing guide GD that assists the toothbrushing action of the toothbrush user. That is, in this example, the tooth brushing guide GD is a tactile guide. In this example as well, the toothbrushing guide GD includes a first part GD1 that indicates the area to be brushed, and a second part GD2 that is an indicator of the period in which toothbrushing should be performed. In this example, the first part GD1 and the second part GD2 have different vibration patterns, for example. For example, by reading the instruction manual, the user of the toothbrush learns that the vibration pattern of the first part GD1 indicates the area to be brushed (for example, the buccal side of the front teeth), and that the vibration pattern of the second part GD2 indicates the area to be brushed. , understand in advance that it indicates the period when you should brush your teeth. Further, while using the toothbrush, the user of the toothbrush performs tooth brushing action on the buccal side of the front teeth based on the vibration pattern of the first part GD1 and the vibration pattern of the second part GD2.

In the example shown in FIGS. 1 and 2, at time tS, the guide output unit 12 starts outputting the toothbrushing guide GD, the detection unit 11 starts detecting the physical quantity, and the storage unit 13 stores the information detected by the detection unit 11. Starts storing the physical quantities. At time tE, the guide output section 12 finishes outputting the tooth brushing guide GD, and the detection section 11 finishes detecting the physical quantity.
In the example shown in FIGS. 1 and 2, the evaluation unit 14 starts evaluating the toothbrushing behavior of the toothbrush user after the detection unit 11 finishes detecting the physical quantity (that is, after time tE). The evaluation unit 14 determines the user's evaluation of the region specified by the first part GD1 based on the physical quantities detected by the detection unit 11 during the period when the second part GD2 is output, which are stored in the storage unit 13. To evaluate the tooth brushing behavior of patients.
Specifically, the evaluation unit 14 calculates the second part GD2 from the physical quantity detected by the detection unit 11 during the period (time tS to time tE) during which the tooth brushing guide GD is output, which is stored in the storage unit 13. A process is executed to extract the physical quantity detected by the detection unit 11 during the period in which the detection unit 11 outputs the physical quantity. Furthermore, the evaluation unit 14 evaluates the user for the site (buccal side of the front teeth) indicated by the first part GD1, without being based on the physical quantity detected by the detection unit 11 during the period when the first part GD1 is output. To evaluate the tooth brushing behavior of patients.
Therefore, in the example shown in FIGS. 1 and 2, the detection section 11 detects the signal during the period when the guide output section 12 is outputting the first part GD1 (that is, during the period when the toothbrush user is not brushing his/her teeth). The toothbrushing behavior of the toothbrush user can be evaluated more accurately than when the toothbrushing behavior of the toothbrush user is evaluated also based on the physical quantity obtained.

If a load sensor is to actually detect that teeth are not being brushed during the period when the guide output unit 12 is outputting the first part GD1 as in Patent Document 2, it is necessary to install a load sensor. Therefore, the cost increases.
On the other hand, in the example shown in FIGS. 1 and 2, during the period when the guide output section 12 is outputting the first part GD1, it is estimated that tooth brushing is not being performed, and the guide output section 12 is outputting the second part GD2. The evaluation unit 14 evaluates only the period during which the output is being output.
Therefore, in the example shown in FIGS. 1 and 2, costs can be reduced compared to the case where a load sensor is installed like the technique described in Patent Document 2.

By the way, the designed output speed of the toothbrushing guide GD by the guide output unit 12 and the actual output speed of the toothbrushing guide GD by the guide output unit 12 may vary depending on individual differences between the toothbrush devices 1 or the usage environment of the toothbrush device 1. The output speed may differ.
In such a case, the physical quantity detected by the detection unit 11 during the period when the guide output unit 12 is not actually outputting the second part GD2 is extracted, and based on the physical quantity, the toothbrush user There is a risk that the tooth brushing behavior of the patient may be evaluated. In other words, in such a case, there is a risk that the toothbrushing behavior of the toothbrush user will be evaluated based on the physical quantity detected by the detection unit 11 during the period when the toothbrush user is not brushing his or her teeth. be.
Therefore, in the examples shown in FIGS. 1 and 2, even if the designed output speed of the tooth-brushing guide GD by the guide output unit 12 and the actual output speed of the tooth-brushing guide GD by the guide output unit 12 are different, Measures are taken to ensure that the physical quantity detected by the detection section 11 is extracted during the period when the guide output section 12 is actually outputting the second part GD2.

Specifically, in the example shown in FIGS. 1 and 2, the detection unit 11 detects a physical quantity at a preset time interval Δt (data pitch) (see FIG. 2(B)). Specifically, during the period (time tS to time tE) during which the guide output unit 12 outputs the tooth brushing guide GD, the detection unit 11 detects the physical quantity at a preset time interval Δt. The designed output speed of the toothbrushing guide GD by the guide output unit 12 and the actual output speed of the toothbrushing guide GD by the guide output unit 12 may vary depending on individual differences in the toothbrush device 1 or the usage environment of the toothbrush device 1. This time interval Δt remains a constant value even if the time interval Δt is different.
In the example shown in FIGS. 1 and 2, when the guide output unit 12 outputs the tooth brushing guide GD at the designed output speed, the period during which the guide output unit 12 outputs the tooth brushing guide GD (from time tS to The length of the tooth brushing guide GD is set so that the number of physical quantity data detected by the detection unit 11 during time tE) is N (see FIG. 2(B)).
In other words, this data number N is the data number N (design data The number is N).
On the other hand, during the period (time tS to time tE) in which the tooth brushing guide GD is outputted by the guide output unit 12, the number of physical quantity data actually detected by the detection unit 11 and stored in the storage unit 13 (actual data number) can be expressed as the length of the period (tE-tS) divided by the time interval Δt ((tE-tS)/Δt).
Furthermore, the output speed ratio, which is the ratio of the actual output speed of the tooth-brushing guide GD by the guide output section 12 to the designed output speed of the tooth-brushing guide GD by the guide output section 12, is calculated by the number of actual data pieces ((tE-tS)/ Δt) divided by the number N of design data (((tE−tS)/Δt)/N).
When the designed output speed of the tooth-brushing guide GD by the guide output section 12 and the actual output speed of the tooth-brushing guide GD by the guide output section 12 are equal, the above-mentioned output speed ratio (((tE-tS)/△ t)/N) becomes 1.

In the example shown in FIGS. 1 and 2, even if the output speed ratio described above is other than 1, the detection unit 11 detects the output speed during the period when the guide output unit 12 is actually outputting the second part GD2. In order to extract the physical quantities that have been calculated, the evaluation unit 14 calculates the above-mentioned number of actual data ((tE-tS)/Δt).
In the examples shown in FIGS. 1 and 2, as described above, the evaluation unit 14 determines the length (tE-tS) of the period during which the toothbrushing guide GD is output (from time tS to time tE) at the time interval Δt. The actual number of data pieces ((tE-tS)/Δt) is calculated by dividing the number of pieces of data ((tE-tS)/Δt). However, in another example, the detection unit 11 calculates the number of actual data pieces ((tE-tS)/Δt) during the period (time tS to time tE) during which the toothbrushing guide GD is output. For example, the evaluation unit 14 may obtain the actual data number by counting the number of physical quantities (actual data number) detected at a preset time interval Δt (data pitch).

Furthermore, in the example shown in FIGS. 1 and 2, the evaluation unit 14 obtains the above-mentioned number N of design data (that is, the preset number N of design data). Furthermore, the evaluation unit 14 calculates the output speed ratio (((tE-tS)/△t)/N) based on the actual data number ((tE-tS)/Δt) and the design data number N. calculate.
Furthermore, the evaluation unit 14 calculates the physical quantity detected by the detection unit 11 during the period in which the second part GD2 is output based on the output speed ratio ((tE-tS)/△t)/N). Execute the extraction process.
In the example shown in FIG. 1 and FIG. 2, in order to identify the period during which the second part GD2 is output, the settings described below are performed in advance, and the processing described below is performed.

In the example shown in FIGS. 1 and 2, when the guide output unit 12 outputs the tooth brushing guide GD at the designed output speed, during the period when the guide output unit 12 outputs the first part GD1 of the tooth brushing guide GD. The length of the first part GD1 is set so that the number of physical quantity data detected by the detection unit 11 is N1 (see FIG. 2(B)).
In other words, this data number N1 is the designed data number N1 of physical quantities to be detected by the detection unit 11 during the period when the first part GD1 is output by the guide output unit 12 (designed first part data number N1). It is.
Further, when the guide output unit 12 outputs the toothbrushing guide GD at the designed output speed, the detection unit 11 detects the second part GD2 of the toothbrushing guide GD during the period in which the guide output unit 12 outputs the second part GD2 of the toothbrushing guide GD. The length of the second part GD2 is set so that the number of physical quantity data is N2 (see FIG. 2(B)).
In other words, this data number N2 is the designed physical quantity data number N2 (designed second part data number N2) that should be detected by the detection unit 11 during the period when the second part GD2 is output by the guide output unit 12. It is.
Furthermore, the order in which the first part GD1 and the second part GD2 are outputted by the guide output unit 12 is set to "GD1→GD2".
The evaluation unit 14 also obtains the above-mentioned number N1 of designed first part data, the above-mentioned number N2 of designed second part data, and the above-mentioned order "GD1→GD2".

The actual data number ((tE-tS)/△t) is calculated by dividing the number of actual data pieces ((tE-tS)/Δt). However, in another example, the detection unit 11 calculates the number of actual data pieces ((tE-tS)/Δt) during the period (time tS to time tE) during which the toothbrushing guide GD is output. For example, the evaluation unit 14 may obtain the actual data number by counting the number of physical quantities (actual data number) detected at a preset time interval Δt (data pitch).
