Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The embodiment provides a toothbrush control method for realizing that skills meet the cleaning requirements of users and noise can be reduced in the using process of the toothbrush.
The principle of the method is described below, specifically as follows:
the basic principle of noise reduction is to control the size and distribution of the sound energy in the frequency domain, and the electric toothbrush must generate sound which can be heard by people because of the vibration (the vibration frequency is in the sound wave range and needs to be avoided in the infrasonic wave range), and further generate larger multiple harmonics because of the vertical power transmission structure of the rotary brush head, so that the sound energy with multiple frequencies is generated more. In order to effectively reduce acoustic energy, a simple theoretical understanding can be first made from the equation for acoustic fluence.
For example, acoustic waves are typical mechanical waves, whose wave equation can be expressed as
x＝Acos(ωt+φ)
Where ω=2pi f, f is the acoustic frequency, Φ is the initial phase of vibration, which can default to 0 phase, t is time, and a is amplitude.
Due to the wave characteristics of the sound wave, the following relation can be obtained by combining the energy flow density definition principle:
where T is the period, ρ is the energy flow density, a is the amplitude, ω=2pi f, f is the acoustic frequency, and Φ is the initial phase of vibration.
That is, it can be understood that the greater the vibration frequency and vibration amplitude, the greater the vibration energy flow density E, i.e., the greater the vibration energy, and thus the greater the sound energy in the air, and the greater the sound appears.
Therefore, based on the basic principle of noise reduction, the vibration frequency needs to be reasonably reduced and the vibration amplitude needs to be reasonably controlled under the condition that the air density is unchanged. However, since the brush head is required to be rotated to generate proper cleaning force on the tooth surface during the use of the toothbrush, reasonable frequency and amplitude are required, and in this embodiment, the basic principle of how to control the sound in the air and to make the sound generated by vibration of the tooth surface during brushing is to reasonably control the frequency and vibration amplitude.
The invention is based on the physical principle and utilizes a software control method to better control the noise generated by the mechanical mechanism, thereby realizing the comfort and no noise of the human ear.
The invention provides a toothbrush control method, referring to fig. 1, fig. 1 is a schematic flow chart of a toothbrush control method provided by an embodiment of the invention, as shown in fig. 1, the method specifically comprises the following steps:
step S101, obtaining a current pressure value corresponding to a current toothbrush head.
Step S102, judging the state of the current toothbrush head according to the current pressure value, acquiring the state of the current toothbrush head and the target vibration frequency and the target swing amplitude corresponding to the current pressure value according to the state of the current toothbrush head and the current pressure value, and controlling the current toothbrush head according to the target vibration frequency and the target swing amplitude.
The toothbrush can be an electric toothbrush with a pendulum type rotary brush head and can be an electric toothbrush with a reciprocating swing brush head.
The state of the current toothbrush head is divided into a first state and a second state, wherein the first state is that the current toothbrush head is not contacted with an object, and the second state is that the current toothbrush head is contacted with the object. For example, if the user is brushing his or her teeth with a toothbrush, the object may be teeth.
In this embodiment, the pressure sensor in the toothbrush can be used to identify whether the brush filaments of the brush head are attached to the object and the strength of the attached object. When the toothbrush head is attached to an object, it is stated that the toothbrush head is cleaning the object, and it is desirable to reduce noise as much as possible while ensuring that the cleaning requirements are met. When the toothbrush head is moved away from the object, which is a non-cleaning requirement, noise is minimized.
Therefore, in the present embodiment, by judging the state of the current toothbrush head according to the current pressure value, corresponding appropriate target vibration frequency and target swing amplitude are given to different states of the current toothbrush head and the current pressure value, and the toothbrush controls the toothbrush head according to the target vibration frequency and the target swing amplitude, so that the toothbrush head moves according to the target vibration frequency and the target swing amplitude. The target vibration frequency is the vibration frequency which meets the cleaning requirement and has the minimum noise amount under the current pressure value, and the target swing amplitude is the swing amplitude which meets the cleaning requirement and has the minimum noise amount under the current pressure value.
The method for acquiring the current pressure value corresponding to the current toothbrush head comprises the following steps:
and S1011, acquiring displacement between a rotor shaft of a motor in the current toothbrush and a stator mechanism of the motor by adopting a pressure sensing sensor in the current toothbrush, and calculating a current pressure value corresponding to the brush head of the current toothbrush according to the displacement.
Wherein, the motor is used for driving the toothbrush head to move, and the vibration frequency and the swing amplitude of the toothbrush head can be controlled.
The pressure sensing sensor can sense and acquire displacement changes generated by relative displacement generated by the brush head tooth pasting and the stator mechanism when the rotor shaft of the motor is used for generating pressure.
In another possible implementation, the sensing acquisition may be performed using a motor shaft bending stress variation sensor.
In another possible implementation, the pressure sensing sensor may be configured to sense changes in displacement of the motor shaft relative to the stationary support that occur when the brush head attachment is generating pressure.
The pressure sensing sensor can also sense the resistance value which is sensed by identifying the passive change characteristic of the swing amplitude of the motor according to the complex change of the resistance which is sensed by the motor when the brush head is attached, when the resistance value of the motor rotor is changed, the swing amplitude of the motor rotor can be changed passively along with the change of the property under the condition that the control parameter is unchanged, so that the resistance change which is sensed by the motor rotor can be calculated, and the pressure value of the brush head and an object can be obtained. In the pressure sensing scheme, the brush head driven by the motor can be controlled by a specific idle pressure identification control parameter when leaving an object, so that the characteristics of prompting performance and passive swing amplitude change caused by the change of measurable resistance are realized, and the swing amplitude of the brush head is better controlled.
In this embodiment, it is possible to determine whether the current state of the toothbrush head is the first state or the second state by:
step 201, if the current pressure value is smaller than a first pressure threshold, determining that the current state of the toothbrush head is the first state.
Step S202, if the current pressure value is not smaller than a first pressure threshold value, judging that the state of the current toothbrush head is the second state.
In general, when the toothbrush head leaves the object, the current pressure value of the toothbrush head should be 0 without considering external factors such as external air resistance, so, in order to improve the accuracy of the toothbrush head state, the embodiment sets the first pressure threshold value by considering external factors such as external air resistance, and uses the first pressure threshold value as the critical value of the toothbrush attached object and the toothbrush attached object to judge the toothbrush head state.
Specifically, if the current pressure value is smaller than the first pressure threshold, the state of the current toothbrush head is judged to be the first state, and if the current pressure value is not smaller than the first pressure threshold, the state of the current toothbrush head is judged to be the second state.
Step S301, if the state of the current toothbrush head is the first state, the target vibration frequency corresponding to the state of the current toothbrush head and the current pressure value is zero, and the target swing amplitude is zero.
Step S302, if the current state of the toothbrush head is the second state, acquiring the second state and a target vibration frequency and a target swing amplitude corresponding to the current pressure value according to the current pressure value.
When the current toothbrush head is not attached to the object, indicating that cleaning is not required, noise of the current toothbrush head can be minimized by stopping rotation and vibration of the head. Specifically, if the current state of the toothbrush head is the first state, the corresponding target vibration frequency is determined to be zero, and the target swing amplitude is determined to be zero. In another possible implementation manner, the vibration frequency may be reduced to the first vibration frequency, the swing amplitude may be reduced to the first swing amplitude, that is, the corresponding target vibration frequency may be determined to be the first vibration frequency, and the target swing amplitude may be determined to be the first swing amplitude, under the condition that it is ensured that the infrasonic wave harmful to the human body is not generated.
When the current toothbrush head is attached to an object, the toothbrush is indicated to be in cleaning action, and noise of the current toothbrush head needs to be minimized under the condition that the toothbrush meets the cleaning requirement. In addition, because different effects may be caused on the object by the toothbrush under different pressures, and the improper vibration frequency and swing amplitude of the toothbrush may be caused on the object under the condition of overlarge pressure, in this embodiment, when the front toothbrush head is attached to the object, the corresponding proper target vibration frequency and target swing amplitude are given for different pressures, so as to protect the object. Specifically, if the current state of the toothbrush head is the second state, the target vibration frequency and the target swing amplitude corresponding to the current pressure value are obtained according to the current pressure value.
In addition, the motor control vibration frequency adopts a single-frequency control mode as far as possible, namely a sine wave control waveform is adopted, and the control signal and the simple harmonic vibration of the motor swing keep synchronous characteristics.
According to the current pressure value, the second state and the target vibration frequency and the target swing amplitude corresponding to the current pressure value are obtained, and the specific steps are as follows:
and S401, if the current pressure value is not smaller than the first pressure threshold value and smaller than the second pressure threshold value, acquiring the second state, wherein the target vibration frequency corresponding to the current pressure value is the vibration frequency in the preset frequency range, and the target swing amplitude is the swing amplitude in the preset amplitude range.
Step S402, if the current pressure value is not less than the second pressure threshold, obtaining the second state, the target vibration frequency corresponding to the current pressure value is zero, and the target vibration amplitude is zero.
The second pressure threshold may be determined based on the ability of the object to withstand the pressure of the toothbrush head, and the second pressure threshold may be determined based on the ability of the object to withstand the pressure of the toothbrush head, e.g. when the toothbrush is used for brushing teeth, the second pressure threshold may be adjusted based on different users, due to different withstand capabilities of the teeth of the users of different age groups to withstand the pressure of the toothbrush head.
For example, when the toothbrush is used for brushing teeth, the second pressure threshold value of the child may be set at 100gf, the second pressure threshold value of the teenager and the elderly may be set at 200gf, the second pressure threshold value of the middle aged may be set at 300gf, and the user who requires an extreme cleaning force for teeth and has no problems such as diseases of teeth, gums and roots may also properly adjust the second pressure threshold value according to his/her comfort needs.
Specifically, if the current pressure value is not less than the first pressure threshold and is less than the second pressure threshold, the second state is acquired, the target vibration frequency corresponding to the current pressure value is the vibration frequency in the preset frequency range, and the target swing amplitude is the swing amplitude in the preset amplitude range. The preset frequency range and the preset amplitude range may be determined according to a vibration frequency and a swing amplitude required to satisfy the cleaning object and reduce noise as much as possible, respectively, wherein the cleaning ability of the toothbrush is mainly determined by the vibration frequency and the reduction of noise is mainly controlled by the swing amplitude.
For example, the first pressure threshold is 50gf, the second pressure threshold is 400gf, the preset amplitude is-30 DEG to +30 DEG, the preset frequency is 60 Hz-350 Hz, when the pressure of the object is 50 gf-400 gf, the target vibration frequency of the current toothbrush head is controlled to be 60 Hz-350 Hz, and the target swing amplitude is-30 DEG to +30 deg.
If the pressure of the toothbrush head exceeds the bearing capacity of the object to the pressure of the toothbrush head, the toothbrush head is not suitable for cleaning at the moment, and the toothbrush can be controlled to stop working so as to protect the object. Specifically, if the current pressure value is not smaller than the second pressure threshold, the second state is acquired, the target vibration frequency corresponding to the current pressure value is zero, and the target vibration amplitude is zero.
In another possible implementation manner, the vibration frequency may be reduced to the second vibration frequency, the swing amplitude may be reduced to the second swing amplitude, that is, the corresponding target vibration frequency may be determined to be the second vibration frequency, and the target swing amplitude may be determined to be the second swing amplitude, under the condition that it is ensured that the infrasonic wave harmful to the human body is not generated.
For example, when the pressure sensor detects that the pressure is too great (e.g., greater than 400 gf), the toothbrush may stop or reduce the vibration frequency and amplitude.
Based on the method, whether the state of the current toothbrush head is not contacted with the object or not is judged according to the current pressure value corresponding to the current toothbrush head, and the corresponding target vibration frequency and the target swing amplitude are obtained according to the state of the current toothbrush head and the current pressure value so as to control the vibration frequency and the swing amplitude of the current toothbrush head. In this technical scheme, current pressure value can embody the laminating condition of current toothbrush and object, say the laminating condition of toothbrush and tooth, the vibration frequency and the swing range of current toothbrush brush head are adjusted to the laminating condition of difference, can toothbrush brush head and object contact, promptly when the clean tooth surface of rotatory brush head is needed, realize rotatory brush head and produce suitable cleaning force on tooth surface, can make the sound that reduces tooth surface vibration and produce when brushing teeth again, realize making an uproar, can realize that the toothbrush brush head does not contact with the object, promptly when need not rotatory brush head clean tooth surface, stop brush head rotation, realize making an uproar, through above-mentioned method, can improve user experience and feel.
In order to better implement the above method, an embodiment of the present invention provides a toothbrush control device, referring to fig. 2, fig. 2 is a block diagram of a toothbrush control device according to an embodiment of the present invention, as shown in fig. 2, the device 20 includes:
