Description

toothbrush device

The present invention relates to a toothbrush device.

This application claims priority based on Japanese Patent Application No. 2019-233342 for which it applied to Japan on December 24, 2019, and uses the content here.

DESCRIPTION OF RELATED ART Conventionally, the device (for example, what is called a smart brush etc.) which performs tooth brushing evaluation based on sensed data and displays the result of the evaluation is known.

In order to perform tooth brushing evaluation, it is necessary to detect a brushing position. When detecting a brushing position directly, image analysis, such as a camera, will be required, and an apparatus will become large-scale. Therefore, in general, the brushing position is estimated indirectly by detecting the angle of a toothbrush. While 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 discriminate the left and right sides of the occlusal surface or the cheek/lingual side.

In order to solve the subject, conventionally, the method of mounting an electrode on a toothbrush head and determining a position in an energized state, and the method of providing a tooth brushing guide are used. Since a toothbrush head becomes large, the method of mounting an electrode on a toothbrush head lacks operability. In an example of the method of providing a tooth brushing guide, by designating a next part to be brushed by a display terminal such as a smartphone, it is possible to accurately estimate the brushing position based on the detected toothbrush angle and the designated part. However, in this example, a user must use a display terminal other than a toothbrush device, and the effort of a user will increase.

Moreover, conventionally, the system which provides feedback to an individual based on brushing performance, and provides the guidance regarding individual brushing is known (for example, refer patent document 1). In patent document 1, oral hygiene devices, such as an electronic toothbrush provided with a toothbrush member, a sensor, a memory|storage part, and a communication circuit, are described. 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, in Patent Document 1, it is not described in which part (that is, movement detection data of a certain time period) of the motion detection data collected by the sensor to determine (calculate) the user's oral hygiene cleaning performance. . Therefore, with the technique of patent document 1, there exists a possibility that it may not be able to discriminate|determine (calculate) accurately the oral hygiene cleaning performance of a user.

Moreover, in patent document 2, it describes about the appropriate use method of an electric toothbrush, and the technique which supports correct brushing. In the technique of patent document 2, an acceleration sensor is provided in a toothbrush, the attitude|position of a toothbrush is obtained from the output of an acceleration sensor, and a brushing site|part is estimated based on the attitude|position of a brush. Moreover, the brushing time of a brushing site|part is measured with a timer. Moreover, based on the measured brushing time, the brushing result for every site|part is evaluated and output.

In addition, in Patent Document 2, since it is not appropriate to record and evaluate the brushing time, brush angle, etc. during which the brush is moving between parts, posture detection, brushing part estimation, and brushing are performed while no load is applied to the brush. It is described to prohibit processing such as measurement of time, estimation of brush angle, detection of brush pressure, and output of brushing results.

By the way, in the technique described in Patent Document 2, a load sensor is provided in order to determine which part of the acceleration data detected by the acceleration sensor (that is, the acceleration data in which time period) should be used to evaluate the brushing, pressure is detected.

Therefore, in the technique of patent document 2, there exists a possibility that cost may increase.

An example of the configuration is shown.

In the example (in detail, the example shown to FIG. 1B) shown in FIG. 1, the toothbrush device 1 is an attachment provided in the toothbrush (not shown). The toothbrush device 1 has a hole 1A into which a handle portion (not shown) of a toothbrush is inserted.

In another example, the toothbrush device 1 may be incorporated in a toothbrush.

In the example (in detail, the example shown to FIG. 1A) shown in FIG. 1, the toothbrush device 1 is the detection part 11, the guide output part 12, the memory|storage part 13, , an evaluation unit 14 is provided. The detection unit 11 detects a predetermined physical quantity related to a user's tooth brushing behavior of a toothbrush (not shown).

In the example shown in FIG. 1, the detection part 11 includes an acceleration sensor (not shown). The detection unit 11 detects a physical quantity (eg, inclination, frequency, amplitude, etc.) related to the user's tooth brushing behavior of the toothbrush 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 user's tooth brushing behavior of the toothbrush by using the angular velocity detected by the gyro sensor.

In another example, the detection unit 11 may include a magnetic sensor (not shown). In this example, the detection part 11 detects the physical quantity regarding the tooth brushing behavior of the user of the toothbrush by using the orientation information obtained by the magnetic sensor.

In another example, the detection part 11 may contain other arbitrary sensors as described in patent document 2, for example.

In the example shown in FIG. 1 (in detail, the example shown in FIG. 1A), the guide output part 12 outputs the tooth brushing guide GD which assists the user's tooth brushing behavior of a toothbrush. The storage unit 13 stores the physical quantity detected by the detection unit 11 when the tooth brushing guide GD is output by the guide output unit 12 . The evaluation unit 14 evaluates the tooth brushing behavior of the user of the toothbrush based on the physical quantity stored in the storage unit 13 and detected by the detection unit 11 .

In the example shown in FIG. 1, the toothbrush device 1 is equipped with the mode in which the evaluation part 14 starts evaluation of the user's tooth brushing behavior of a toothbrush after detection of the physical quantity by the detection part 11 is complete|finished .

In another example, the toothbrush device 1 may be equipped with the mode in which the evaluation part 14 starts evaluation of the user's tooth brushing behavior of a toothbrush before detection of the physical quantity by the detection part 11 is complete other than that mode. .

2 is a view showing an example of the tooth brushing guide GD output by the guide output unit 12, and the like. In detail, FIG. 2A illustrates a first part GD1 and a second part GD2 included in the tooth brushing guide GD output by the guide output unit 12 . 2B shows the number of design data, which is the data number of the design physical quantity to be detected by the detection unit 11 during the period (time tS to time tE) during which the tooth brushing guide GD is output by the guide output unit 12 . N and the like are shown.

In the example shown in FIG. 1 and FIG. 2, the guide output part 12 is equipped with the speaker. The guide output unit 12 is a tooth brushing guide GD that assists the user's tooth brushing behavior of the toothbrush, and outputs a voice. That is, in the example shown in FIG. 1 and FIG. 2, the tooth brushing guide GD is an auditory guide. The tooth brushing guide GD includes a first part GD1 that indicates a site where tooth brushing is to be performed, and a second part GD2 that serves as an index of the period during which tooth brushing should be performed.

The guide output unit 12 is a first part GD1 of the tooth brushing guide GD, for example, "Come on, start brushing your teeth! Let's do it with this-shaped mouth! Wipe your front teeth!” is output. As a result, even when the user of the toothbrush is an infant, the user of the toothbrush can easily understand that the site|part to which tooth brushing should be performed is the cheek side (lip side) of an incisor.

Next, the guide output part 12 outputs the audio|voice of "Chika Chika Chika Chika Chika Chika Chika Chika Chika Chika" as 2nd part GD2 of tooth brushing guide GD, for example. As a result, even when the user of a toothbrush is an infant, the user of a toothbrush can understand easily that the period in which 2nd part GD2 is output is a period which should perform tooth brushing.

In another example, as 1st part GD1, audio|voices other than the above-mentioned audio|voice may be output by the guide output part 12, and as 2nd part GD2, audio|voices other than the above-mentioned audio|voice are output by the guide output part 12. may be output.

In another example, the guide output part 12 may be equipped with the vibration generating device (not shown). In this example, the guide output unit 12 outputs a vibration as a tooth brushing guide GD that assists the user of the toothbrush with a tooth brushing action. That is, in this example, the tooth brushing guide GD is a tactile guide. Also in this example, 1st part GD1 which instructs the site|part in which tooth brushing should be performed, and 2nd part GD2 used as the parameter|index of the period in which tooth brushing should be performed are contained in tooth brushing guide GD. In this example, in 1st part GD1 and 2nd part GD2, a vibration pattern differs, for example. The user of the toothbrush, for example, by reading the instruction manual, the vibration pattern of 1st part GD1 shows the site|part (for example, the cheek side of an incisor) which should be brushed, and the vibration pattern of 2nd part GD2, Understand in advance the purpose of indicating the period during which tooth brushing should be performed. Moreover, the user of a toothbrush performs a tooth-brushing action with respect to the cheek side of an incisor based on the vibration pattern of 1st part GD1 and the vibration pattern of 2nd part GD2 during use of a toothbrush.

In the example shown in FIGS. 1 and 2, at time tS, while the guide output part 12 starts outputting the tooth brushing guide GD, the detection part 11 starts detection of a physical quantity, and the memory|storage part 13 starts storage of the physical quantity detected by the detection unit 11 . When the time tE comes, the guide output section 12 ends the output of the tooth brushing guide GD, and the detection section 11 ends the detection of the physical quantity.

In the example shown in FIG. 1 and FIG. 2, the evaluation part 14 starts evaluation of the tooth brushing behavior of the user of the toothbrush after detection of the physical quantity by the detection part 11 is complete|finished (that is, after time tE). do. The evaluation unit 14 is stored in the storage unit 13, and based on the physical quantity detected by the detection unit 11 during the period during which the second part GD2 is being outputted, to the site indicated by the first part GD1. evaluation of the user's tooth brushing behavior.

In detail, the evaluation unit 14 calculates a second value from the physical quantity stored in the storage unit 13 and detected by the detection unit 11 during the period (time tS to time tE) during which the tooth brushing guide GD is output. The process of extracting the physical quantity detected by the detection part 11 during the period in which the part GD2 is being output is performed. In addition, the evaluation unit 14 is not based on the physical quantity detected by the detection unit 11 during the period in which the first part GD1 is being output, but rather the user for the site indicated by the first part GD1 (the cheek side of the incisors). to evaluate the tooth brushing behavior of

Therefore, in the example shown to FIG. 1 and FIG. 2, the detection part 11 during the period (that is, during the period in which the user of the toothbrush is not brushing a tooth) in which the guide output part 12 is outputting 1st parts GD1. ), the tooth brushing behavior of the user of the toothbrush can be evaluated more accurately than when the user's tooth brushing behavior of the toothbrush is evaluated based on the physical quantity detected by .

Since installation of a load sensor is required when actually detecting that tooth brushing is not performed with a load sensor like patent document 2 during the period in which the guide output part 12 is outputting 1st part GD1, the cost increases

On the other hand, in the example shown to FIG. 1 and FIG. 2, it is estimated that tooth brushing is not performed during the period in which the guide output part 12 is outputting 1st part GD1, and the guide output part 12 is 2nd part GD2 Only during the period in which .

Therefore, in the example shown in FIG. 1 and FIG. 2, cost can be suppressed rather than the case where a load sensor is provided like the technique of patent document 2.

By the way, according to individual differences of the toothbrush device 1, or according to the usage environment of the toothbrush device 1, the design output speed of the tooth brushing guide GD by the guide output unit 12, and the guide output unit 12 The actual output speed of the tooth brushing guide GD by .

In such a case, the physical quantity detected by the detection unit 11 is extracted during the period in which the guide output unit 12 is not actually outputting the second part GD2, and based on the physical quantity, There exists a possibility that evaluation may be performed. That is, in such a case, there exists a possibility that evaluation of the tooth brushing behavior of the user of the toothbrush may be performed based on the physical quantity detected by the detection part 11 during the period during which the user of the toothbrush is not performing tooth brushing.

Therefore, in the example shown in FIGS. 1 and 2, when the design output speed of the tooth brushing guide GD by the guide output part 12 and the actual output speed of the tooth brushing guide GD by the guide output part 12 differ In Edo, a countermeasure is being taken so that the physical quantity detected by the detection part 11 is extracted during the period in which the guide output part 12 is actually outputting 2nd part GD2.

Specifically, in the examples shown in Figs. 1 and 2, the detection unit 11 detects a physical quantity at a preset time interval ?t (data pitch) (refer to Fig. 2B). In detail, during the period during which the guide output unit 12 outputs the tooth brushing guide GD (time tS to time tE), the detection unit 11 detects a physical quantity at a preset time interval Δt. According to the individual difference of the toothbrush device 1, or according to the usage environment of the toothbrush device 1, the design output speed of the tooth brushing guide GD by the guide output unit 12 and the output speed of the guide output unit 12 Even when the actual output speed of the tooth brushing guide GD is different, this time interval Δt becomes a constant value.

In addition, in the example shown in FIGS. 1 and 2 , when the guide output unit 12 outputs the tooth brushing guide GD at the design output speed, the guide output unit 12 outputs the tooth brushing guide GD ( The length of the tooth brushing guide GD is set so that the data number of the physical quantity detected by the detection unit 11 during the time tS to time tE) becomes N (refer to FIG. 2(B) ).

That is, this data number N is the data number N of a physical quantity by design to be detected by the detection unit 11 during the period (time tS to time tE) during which the tooth brushing guide GD is output by the guide output unit 12 (design number of data N).

On the other hand, during the period (time tS to time tE) during which the tooth brushing guide GD is output by the guide output unit 12 , the data number of the physical quantity actually detected by the detection unit 11 and stored in the storage unit 13 . (the number of actual data) can be expressed by dividing the length of the period (tE-tS) by the time interval Δt ((tE-tS)/Δt).

In addition, the output speed ratio, which is the ratio of the actual output speed of the tooth brushing guide GD by the guide output unit 12 to the design output speed of the tooth brushing guide GD by the guide output unit 12, is the number of actual data ((tE) -tS)/Δt) divided by the number of design data N can be expressed by (((tE-tS)/Δt)/N).

When the design 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 equal, the above-described output speed ratio (((tE− tS)/Δt)/N) becomes 1.

In the example shown in FIG. 1 and FIG. 2, even if it is a case where the above-mentioned output speed ratio is other than 1, the physical quantity detected by the detection part 11 during the period in which the guide output part 12 is actually outputting 2nd part GD2. In order to be extracted, the evaluation unit 14 calculates the above-described actual data number ((tE-tS)/Δt).

In the example shown in FIGS. 1 and 2, as described above, the evaluation unit 14 sets the length tE-tS of the period (time tS to time tE) during which the tooth brushing guide GD is output as the time interval Δt. The actual data number ((tE-tS)/Δt) is calculated by dividing, but in another example, the detection unit 11 performs a preset time interval Δt during the period (time tS to time tE) during which the tooth brushing guide GD is output. The number of detected physical quantities (actual data number) may be counted by (data pitch), and, for example, the evaluation unit 14 may acquire the actual data number.

In addition, in the example shown in FIG. 1 and FIG. 2, the evaluation part 14 acquires the above-mentioned design data number N (namely, preset design data number N). Further, the evaluation unit 14 calculates the above-described output speed ratio (((tE-tS)/Δt)/N) based on the actual data number ((tE-tS)/Δt) and the design data number N do.

Moreover, the evaluation part 14 calculates the physical quantity detected by the detection part 11 during the period in which 2nd part GD2 is being output based on the output speed ratio (((tE-tS)/Δt)/N) Execute the extraction process.

In the example shown in FIG. 1 and FIG. 2, in order to identify the period in which 2nd part GD2 is output, the setting mentioned later is performed beforehand, and the process mentioned later 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 design output speed, the guide output unit 12 outputs the first part GD1 of the tooth brushing guide GD, The length of 1st part GD1 is set so that the data number of the physical quantity detected by the detection part 11 during a certain period may be N1 (refer FIG.2(B)).

That is, the data number N1 is the data number N1 of the design physical quantity to be detected by the detection unit 11 during the period in which the first part GD1 is output by the guide output unit 12 (design first part data number N1). )to be.

In addition, when the guide output unit 12 outputs the tooth brushing guide GD at the design output speed, the detection unit 11 detects the second part GD2 of the tooth brushing guide GD while the guide output unit 12 is outputting the second part GD2. The length of 2nd part GD2 is set so that the data number of the detected physical quantity may become N2 (refer FIG.2(B)).

That is, this data number N2 is the data number N2 (design 2nd part data number N2) of the design physical quantity to be detected by the detection part 11 during the period in which the 2nd part GD2 is being output by the guide output part 12. )to be.
