Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
The common mode of the electric toothbrush in the market at present is that the vibration generated by a short pause is used as the reminding of one-time tooth brushing and zone changing, and the zone changing reminding mode is simple to operate, but is not too hard and rough, and has poor user experience; still another advanced warning mode is to carry out the pronunciation warning through toothbrush built-in voice module, but the shortcoming is that structural design is complicated, has increased the cost of product to if only increase a pronunciation chip for the enhancement district warning function that trades, such design is not too big material small-size. In view of the above, the present invention provides an electric toothbrush using a motor sound generation technology to alleviate the above-mentioned technical problems.
Example one
An embodiment of the present invention provides an electric toothbrush, as shown in fig. 1, including: a key 101, a central processing unit 102, a motor driving circuit 103 and a motor 104 which are connected in sequence.
And the key 101 is used for generating an action instruction after being pressed by a user and sending the action instruction to the central processor 102.
And the central processor 102 is used for determining at least one pulse signal and the duration of each pulse signal based on the action command after receiving the action command.
If the number of the pulse signals is multiple, the central processing unit 102 is further configured to sequentially send at least one pulse signal to the motor driving circuit 103 based on a preset sending sequence and duration.
And a motor driving circuit 103 for amplifying each received pulse signal and driving the motor 104 using the amplified pulse signal to vibrate the motor 104.
The electric toothbrush is capable of vibrating at a high speed because of the vibration of the built-in motor 104, the motor 104 is composed of a stator, which is generally a permanent magnet, and a rotor having a winding, and the rotor is rotated by the force applied to the energized winding in a magnetic field. The vibration caused by the electromagnetic force during the operation of the motor 104 is transmitted to the surrounding space through the motor itself, causing the vibration of air particles to cause sound waves, which can be felt by human ears when the vibration frequency of the sound waves is in the range of 20HZ-20KHZ, which is the electromagnetic noise generated by the motor 104.
The electric toothbrush provided by the invention is based on the principle of electromagnetic noise, if pulse signals with different frequencies are input to the motor 104, the frequency of the electromagnetic noise generated by the motor 104 is different, and each note in the song has a corresponding frequency, therefore, the inventor thinks that if the frequency of the electromagnetic noise generated by the motor 104 is controlled to be the same as the frequency of the note in the preset song when zone change reminding is carried out, and further the duration time (music beat) of the pulse signals is controlled, the motor 104 can generate electronic music, so that the aim of zone change reminding is achieved, and because the motor 104 does not have a pause behavior in the whole tooth brushing process, the user experience is good, and meanwhile, the interestingness of the product is enhanced.
Specifically, the electric toothbrush provided by the embodiment of the invention comprises the key 101, the central processing unit 102, the motor driving circuit 103 and the motor 104 which are connected in sequence, and necessary structures such as a brush head and a shell of the electric toothbrush are common features of all electric toothbrushes, so that the structural relationship of the electric toothbrush is not particularly emphasized, and the electric toothbrush is similar to the appearance structure of products on the market. For the keys 101, the embodiment of the present invention does not limit the specific number, and the user may set a separate power switch key 101 and a mode selection key 101, or implement the operations of turning on, mode selecting, and turning off the electric toothbrush through the same key 101, and as long as the user presses the key 101, the user will send an action instruction according to the preset function and send the action instruction to the central processing unit 102.
For the case of an electric toothbrush with only one button 101, and 2 operating modes (first and second) are preset for illustration: when a user presses the key 101 once, it is determined that an opening instruction is sent and the operation is performed in the first mode by default, if the user presses the key once again, it is determined that an instruction which is performed in the second mode is sent, and if the user presses the key once again, it is determined that a shutdown instruction is sent, and for the first mode and the second mode, the corresponding action instructions are different, and the vibration strategy of the motor 104 is different.
After receiving the action command sent by the key 101, the central processing unit 102 determines at least one pulse signal and the duration of each pulse signal based on the action command, and if the number of the pulse signals is multiple, the central processing unit 102 can send the at least one pulse signal to the motor driving circuit 103 according to a preset sending sequence and the duration of the pulse signals in sequence, and if the number of the pulse signals is only one, the central processing unit 102 sends the pulse signal to the motor driving circuit 103. In some embodiments, the Pulse signal is in the form of a PWM (Pulse width modulation) wave.
For convenience of understanding, the operation process of the electric toothbrush with only one button 101 is further illustrated, assuming that the brushing process is 2 minutes, and the zone changing reminder is performed every 30s, if the central processing unit 102 receives an instruction to operate in the second mode, the 2 minute operation process is divided into 1 st 30s vibration, 1 st zone changing reminder, 2 nd 30s vibration, 2 nd zone changing reminder, 3 rd 30s vibration, 3 rd zone changing reminder, 4 th 30s vibration and shutdown according to a preset vibration strategy of the motor 104.
The vibration frequency of the motor 104 in the 30s tooth brushing vibration process is scientifically established by research personnel according to tooth brushing effect and market demand, the embodiment of the invention does not improve the vibration frequency of the process, but for the middle 3 times of zone change reminding, the invention is realized by controlling the vibration frequency of the motor 104 and the vibration duration of each frequency, therefore, when receiving an instruction of operating in the second mode, the central processor 102 determines the vibration frequency (one vibration frequency corresponds to one pulse signal) of each stage in the tooth brushing process and the duration of each pulse signal according to a preset vibration strategy, and simultaneously sends the vibration frequency and the duration of each pulse signal to the motor driving circuit 103 in sequence according to a preset sending sequence, the embodiment of the invention does not limit the number of pulse signals used in the zone change reminding and the duration of each pulse signal, the user can set according to the actual demand, that is to say, through control beat (duration), every tone will broadcast certain time, and the note rhythm is divided into one bat, half bat, 1/4 bat, 1/8 bat, and is preferred, sets up the time of one bat of note for 1 second, and then half bat is 0.5 second, and 1/4 bat is 0.25 second, and 1/8 bat is 0.125 seconds, so the user plays out through giving corresponding beat for every pulse signal, and motor 104 just can realize the function of playing the electronic music.
Since the strength of the pulse signal output by the cpu 102 is not enough to drive the motor 104 to vibrate, a motor driving circuit 103 is disposed between the cpu 102 and the motor 104, and the motor driving circuit 103 is mainly used to amplify each received pulse signal and drive the motor 104 by using the amplified pulse signal to vibrate the motor 104.
In the prior art, when a user switches a tooth brushing mode or tooth brushing strength of an electric toothbrush, the user can select to press a corresponding key 101, the traditional electric toothbrush has no feedback when the key 101 is pressed, and the user cannot perceive whether the switch is successful or not, so that the user experience is poor.
For example, when the user switches the brushing mode or brushing strength of the electric toothbrush, the user may preset the cpu 102 to send one or more pulse signals to the motor, and if the pulse signal is a pulse signal, the motor 104 vibrates only once, and the vibration time may be set by the user according to actual needs; if the central processing unit 102 is set to transmit a plurality of pulse signals, corresponding electronic music can be generated by controlling the duration of the plurality of pulse signals, so that the electric toothbrush can feed back the key actions of the user in a vibration mode and a music mode, and the user experience is enhanced.
According to the embodiment of the invention, the motor sound production technology is used for producing music to remind when the tooth brushing is performed and the region is changed, compared with the traditional mode that the motor is suspended, the use experience of a user can be optimized, the interestingness of the user is increased, the motor sound production technology is more practical compared with the mode that a voice module is added, the material cost is not required to be increased, the motor 104 can vibrate correspondingly according to the key of the user every time, the feedback is given to the user, and the user experience is enhanced.
In the prior art, the electric toothbrush is operated to realize the zone-changing reminding function by suspending the motor 104, but such a treatment mode is too hard and rough, and the user experience is poor, compared with the prior art, the invention provides the electric toothbrush, which comprises: the user presses the key 101 to generate an action instruction and sends the action instruction to the central processing unit 102, the central processing unit 102 determines at least one pulse signal and the duration of each pulse signal based on the action instruction after receiving the action instruction, if the number of the pulse signals is multiple, the central processing unit 102 sends the at least one pulse signal to the motor driving circuit 103 in sequence based on a preset sending sequence and the duration, and then the motor driving circuit 103 amplifies each received pulse signal and drives the motor 104 by using the amplified pulse signal to enable the motor 104 to vibrate. The electric toothbrush provided by the invention can control the motor 104 to vibrate to generate electronic music by controlling the pulse signals with different frequencies to last for different times, so as to achieve the effect of zone-changing reminding, the operation that the motor 104 is suspended does not exist in the running process, and the electric toothbrush can provide vibration feedback when a user presses a key, so that the technical problem of poor user experience of the electric toothbrush in the prior art can be effectively solved.
