具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本发明进行进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
图1示出了本发明实施例提供的该智能牙刷的控制电路10应用系统框图,其中该控制电路10应用于智能牙刷中,为了便于说明,仅示出了与本发明实施例相关的部分,详述如下:
如图1所述,控制电路10通过智能终端20与云端服务器30连接,该控制电路10所检测得到的口腔数据通过该智能终端20无线传输至云端服务器30;需要说明的是,云端服务器30作为一种高度分布式、高度虚拟化的大数据处理平台,可集中并行通过智能终端20传输的各种口腔数据,并且存储和处理不同类型的数据,进行大规模的数据建模以及分析;相比于传统的物理存储介质,云端服务器30具有存储量大、数据处理速度快、传输范围广以及高智能化的优点。
可选的,智能终端20为中转站、路由器、计算机、U盘、读卡器、计算机存储器、智能手机以及平板电脑等;可选的,安装在智能终端20上的APP(Application,应用程序)具有数据的传递以及显示功能,通过该APP即可将控制电路10所检测得到的口腔数据传输至云端服务器30;在云端服务器30中提前存储着多种智能数据处理算法,相比于传统的统计方法,这些人工智能算法可对于所采集到的大数据进行智能处理后即可分析得出用户的历史刷牙行为信息以及用户的牙齿健康状态变化情况;一方面,当云端服务器30接收口腔数据时,基于智能数据处理算法对口腔数据进行深度的处理、分析以及数据挖掘,进而得到用户的刷牙行为状态以及牙齿的健康状态,并记录用户的历史刷牙信息;另一方面,控制电路10根据口腔数据得到控制信号,此时控制 电路10中的各个功能模块基于该控制信号即可实时向用户发出各种刷牙行为指导信息,如左右手刷牙指导信息、智能唤醒信息等,控制电路10中的多个功能模块通过发出多种刷牙行为指导信息即可使用户始终保持最佳的刷牙状态;同时控制电路10将控制信号发送至智能终端20上的APP,用户可以APP实时监控自己刷牙行为以及牙齿健康状况,并且在用户刷牙过程中通过APP可实时向用户发出刷牙行为建议以及提示信息等;从而当用户使用包含控制电路10的智能牙刷时,用户可随时随地的监控自己的刷牙行为,并且通过智能数据处理算法分析得出用户的牙齿健康状况,记录用户的牙齿健康状况变化量,从而提供用户的智能体验感。
图2示出了本发明实施例提供的智能牙刷的控制电路10模块结构,为了便于说明,仅示出了与本发明实施例相关的部分,详述如下:
如图1所示,智能牙刷的控制电路10包括:主控模块101、刷头模块102、位置检测模块103以及压力检测模块104;其中主控模块101通过智能终端20与云端服务器30连接,可选的,主控模块101通过智能终端20与云端服务器30无线连接,进而主控模块101与云端服务器30之间能够实现双向数据交互操作;若用户在刷牙时,主控模块101接收刷头类型、刷牙姿态数据以及刷牙压力数据等,并且将所接收的数据通过汇总分类得到口腔数据,该口腔数据可包含用户在使用智能牙刷牙时所产生的各种类型数据。该口腔数据包括但不仅限于刷头类型、刷牙姿态数据以及刷牙压力数据,云端服务器30通过该口腔数据即可全面地评估用户的刷牙行为状态;主控模块101将该口腔数据上传至云端服务器30,实现对于该口腔数据的大数据分析操作,进而实现用户刷牙行为的实时监控。
同时,主控模块101还根据口腔数据生成控制信号;由于通过口腔数据即 可全面地分析得出用户的刷牙行为信息,因此主控101根据口腔数据进行处理分析后生成控制信号,该控制信号即包含了用户的所有刷牙行为信息以及状态数据。
刷头模块102与主控模块101连接,刷头模块102检测用户所选择的刷头的类型特征得到刷头类型,并将刷头类型上传至主控模块101,主控模块101将控制信号传输至刷头模块102,刷头模块102根据该控制信号得到刷头指示信号;可选的,所述的刷头类型特征包括刷头的型号标识。根据该型号标识可以得到刷头类型。另外,还可以包括物理构造、制造材料、使用寿命、用户的刷牙模式、用户的刷牙力度以及用户的刷牙时长等。
需要说明的是,由于用户在一定的时期内使用同一把牙刷进行刷牙,而随着用户刷牙时间的增长,牙刷的刷头也出现一定的损坏并且也会聚集大量的有害细菌,进而损害用户的口腔健康;在实际应用过程中,按照每天两次的有效刷牙,则牙刷的正常使用寿命为90天;若用户所选择的刷头的类型特征不同,则刷头的寿命、刷头的刷毛类型、刷毛特性、物理构造等方面具有较大的差异,因此刷头模块102通过检测用户所选择的刷头的类型得到刷头类型,通过该刷头类型可全面地检测用户的刷头使用情况;当主控模块101将该刷头类型上传至主控模块101时,主控模块101根据所述刷头类型分析得到用户所选择智能牙刷的刷头使用信息,其中刷头使用信息包括但不限于用户所使用的刷头寿命是否已经到期,并据此生成控制信号;当主控模块101将控制信号传输至刷头模块102时,刷头模块102根据控制信号得到刷头指示信号,则该控制电路10会根据该刷头指示信号通过语音播报、震动、光等方式提醒用户即使更换刷头;若用户所使用的刷头超过该刷头的使用寿命,则控制电路10根据该刷头指示信号不仅及时发出警报提示信息,甚至采取相应的措施使该刷头停止工作,以 防用户长期使用该废旧的刷头对口腔健康造成不良影响。
进一步地,主控模块101接收了刷头类型并据此生成了控制信号,通过该控制信号即可获知用户所使用的刷头信息,如通过该控制信号可预测出用户所选择的刷头的物理状态以及剩余寿命等信息;当主控模块101将控制信号传输至智能终端20,通过安装在智能终端20上的APP以可视化直观的界面方式实时提醒用户,需要及时更换牙刷刷头;从而从各个方面保证用户的刷头处于最佳的工作状态。
更近一步地,由于刷头模块102接收由主控模块101生成的控制信号,因此可通过控制信号修改刷头的参数,其中所述刷头的参数包括:刷牙的模式、力度、时长等,并将修改后的刷头的参数保存在控制电路10中,若用户下次使用该刷牙时,主控模块101会直接读取用户修改后的刷头的参数,以匹配智能牙刷的刷牙模式、力度、时长等;从而用户与智能牙刷之间能够极性双向数据交互操作。
位置检测模块103与主控模块101连接,位置检测模块103检测用户刷牙姿态得到刷牙姿态数据,并将该刷牙姿态数据传输至主控模块101;由于用户在刷牙时,正确的刷牙位置对于清洁牙齿以及牙齿健康具有即为重要的作用,而实际操作中,用户往往存在不良的刷牙习惯,从而导致用户的刷牙效果不佳;为了纠正用户的刷牙习惯,通过位置检测模块103实时检测用户刷牙姿态得到刷牙姿态数据,该刷牙姿态数据包括用户在刷牙过程中的位置信息;主控模块101根据该刷牙姿态数据生成控制信号,该控制信号包括用户的刷牙姿态信息,主控模块101将该控制信号传输至位置检测模块103,位置检测模块根据控制信号得到刷牙姿态引导信号,该刷牙姿态引导信号用于向用户发出刷牙姿态实时引导信息,例如该刷牙姿态实时引导信息包括:左右手刷牙、横刷、错误刷 牙姿态提醒以及智能唤醒等;同时主控模块101将该控制信号上传至智能终端20中的APP,通过APP用户即可看到自身的刷牙位置;同时智能终端20将刷牙姿态数据上传至云端服务器30,通过云端服务器30中的大数据分析算法即可实时展示用户在多区多面的刷牙结果,并且实时引导用户调整刷牙姿态,从而多方面保证用户刷牙时获得最佳的刷牙效果。
压力检测模块104与主控模块101连接,压力检测模块104检测用户刷牙压力得到刷牙压力数据,并将该刷牙压力数据传输至主控模块101;若用户在刷牙的过程中,若用户的刷牙压力过大,则牙刷的刷毛会对牙龈以及牙齿造成一定磨损;反之若用户的刷牙压力过小,则通过该牙刷无法起到清洁牙齿的作用;因此需要适当的刷牙压力来保持最佳的刷牙效果;通过压力检测模块104可实时检测用户的刷牙压力并得到刷牙压力数据,通过该刷牙压力数据可检测用户在刷牙过程中的刷牙压力;主控模块101根据该刷牙压力数据生成控制信号,当压力检测模块104接受到该控制信号时,压力检测模块104根据该控制信号生成压力检测信号,通过该压力检测信号就可向用户发出实时的刷牙压力过大/过小的提示信息、防风溅提示信息等。
具体的,若控制电路10检测到用户的刷牙压力过大,则压力检测模块104根据压力检测信号适当地降低牙刷振动的频率以及振动力度,从而减少牙刷的刷毛对牙齿的磨损,同时也可以通过电机震动、指示灯和扬声器提示信息以提示用户注意刷牙压力;或者用户在使用智能牙刷进行刷牙的过程中,高频率的电机振动会使得牙膏脱落或者牙膏泡沫四处飞溅,当用户开启智能进行刷牙时用户并没有进行实际刷牙,即智能牙刷的刷头并未进入用户的口腔,此时通过控制电路10所检测到的刷牙压力是一个较小的值,则此时压力检测模块104根据压力检测信号适当地降低振动的频率和振动幅度,以防止牙膏脱落或者牙 膏沫飞溅;随后若用户实际使用智能牙刷进行刷牙(即智能牙刷的刷头进入用户的口腔后)时,通过控制电路10所检测得到的刷牙压力会变大,当该刷牙压力超过预定的阀值时,智能牙刷根据该压力检测信号开始正常工作,即牙刷的电机正常开始运转工作。
作为其中的一个优选实施例,压力检测模块104可根据该压力检测信号可记录用户的刷牙总时长;可选的,当压力检测模块104检测到用户刷牙时实际处于牙膏飞溅状态,此时压力检测模块104根据该压力检测信号可获知用户并未实际刷牙,则压力检测模块并不会将刷牙牙膏飞溅的时间计入刷牙的总时长,进而提高了压力检测模块104根据压力检测信号记录用户总时长的精准度,控制电路10可根据该压力检测信号更加全面地评估用户的刷牙压力情况。
具体的,主控模块101将该刷牙压力数据通过智能终端20上传至云端服务器30,通过对于刷牙压力数据的智能处理分析评价得到用户的实际刷牙情况;因此通过存储在云端服务器30中的智能算法即可对用户的历史刷牙压力数据进行更加全面、深入的分析,预测和评价用户的刷牙健康状况。
通过本发明实施例,在智能牙刷的控制电路10中,一方面,主控模块101将用户的口腔数据通过智能终端20上传至云端服务器30中,其中该口腔数据包含了用户在刷牙过程中所产生的各种刷牙数据,当云端服务器30接收该口腔数据时,基于多种数据处理算法实时地对该口腔数据进行深度处理和分析,通过对于口腔数据进行深度处理和分析后即可全面地监控用户的刷牙行为以及口腔健康状况,提高用户在使用智能牙刷时的智能体验感和舒适感;另一方面,主控模块101根据口腔数据生成控制信号,该控制信号全面地包括了用户的刷牙行为,因此刷头模块102、位置检测模块103以及压力检测模块104分别该控制信号同步发出刷牙行为的纠正与引导信息,纠正用户的不良刷牙行 为,使用户始终保持最佳的刷牙状态,维护用户的牙齿健康;同时用户还可通过智能终端20上的APP获知自己的刷牙行为,用户能够更加直观地了解自己的实时刷牙行为以及口腔健康;从而有效地解决了现有技术中智能牙刷的控制电路对刷牙数据进行深层次分析和处理、以及用户的智能体验感不佳的问题。

作为一种可选的实施方式,图12示出了本发明实施例提供的电机驱动模 块1001的电路结构,详述如下:

作为一种可扩展的实施方式,扬声器模块1003与主控模块101连接时,扬声器模块1003还可用于发出其它功能的语音提醒,如:开机、横刷等姿势错误、刷头更换和电量不足等。
作为一种可选的实施方式,图15示出了本发明实施例提供的位置检测模块103的电路结构,详述如下:
如图15所示,位置检测模块103包括:加速度传感器、第八电容C8、第九电容C9以及第十电容C10;其中,加速度传感器采用加速度传感器芯片U4来实现相应的功能,加速度传感器芯片U4的串行通信管脚SCL/SPC、SDA/SDI以及SAO/SDO接主控模块101,用于将刷牙姿态数据传输至主控模块101,并接收来自于控制模块101生成的控制信号;加速度传感器芯片U4的电源管脚VDDIO、CS以及INT接主控模块101,用于接入稳压信号VCC,通过该稳压信号VCC可向位置检测模块103输出稳定的直流电源;加速度传感器芯片U4的接地管脚接地GND,第八电容C8的第一端和第九电容C9的第一端共接于地GND,第八电容C8的第二端接加速度传感器芯片U4的串行通信管脚 VDDIO,第九电容C9的第二端接加速度传感器芯片U4的电源管脚VDD,加速度传感器芯片U4的电源驱动管脚REGOUT通过第十电容C10接地GND。
可选的,加速度传感器芯片U4为ICM-20602系列芯片。
结合以上图15所示出的位置检测模块103的电路结构,位置检测模块103通过实时检测用户刷牙姿态进而得到刷牙姿态数据,当主控模块101将该刷牙姿态数据上传至云端服务器30时,基于大数据分析算法对刷牙姿态数据进行处理分析,以评价用户的历史刷牙姿态情况;同时主控模块101根据用户的刷牙姿态数据实时生成控制信号,当智能终端20接收该控制信号后,即可在智能终端20中的APP中显示用户的刷牙位置,并且向用户发出刷牙位置引导和提示信息。
作为作为一种可选的实施方式,在上述位置检测模块103的电路结构中,加速度传感器为三轴加速度传感器、六轴加速度传感器或者九轴加速度传感器,若将用户的口腔分为6个区,则采用不同类型的加速度传感器即可检测到牙刷在用户口腔内的不同刷牙姿态结果。
例如,若加速度传感器为三轴加速度传感器,则位置检测模块103通过三轴加速度传感器实现对于用户口腔的6区16面盲刷位置检测,并且由于主控模块101将传输至智能终端20,用户在刷牙过程中通过安装在智能终端20上的APP同步看到刷牙位置引导,以实现纠正不良的刷牙行为习惯;并且控制模块101将刷牙姿态数据上传至云端服务器30,通过云端大数据分析算法,即可向用户提供6区16面历史刷牙统计结果。
例如,若加速度传感器为六轴加速度传感器,则位置检测模块103通过三轴加速度传感器+三轴陀螺仪传感器实现对于用户口腔的6区16面盲刷位置检测;若加速度传感器为九轴加速度传感器,则位置检测模块103通过三轴加速 度传感器+三轴陀螺仪传感器+三轴地磁传感器实现对于用户口腔的6区16面盲刷位置检测;相比于上述三轴加速度传感器,此时加速度传感器为六轴加速度传感器或者九轴加速度传感器时,控制电路10不但可以根据日常生活过程中的刷牙姿态数据对用户进行同步智能引导和分析,而且通过六轴加速度传感器或者九轴加速度传感器可以保证用户无论是左手刷牙还是右手刷牙,都不会影响位置检测模块103对用户的刷牙姿态数据的检测结果,从而使位置检测模块103对用户刷牙姿态检测具有跟高的精确性,提高了控制电路10对用户刷牙姿态引导的实时性。

其中,存储模块1601与主控模块101连接,存储模块1601根据控制信号能够存储口腔数据,由于用户在刷牙过程中会产生的大量的刷牙数据,其中包括:刷头类型、刷牙姿态数据以及刷牙压力数据等,当主控模块101将上述数据汇总得到口腔数据,通过存储模块存储用户的口腔数据以记录用户的历史刷牙数据,通过云端服务器30中的云端智能数据处理算法对用户的历史口腔数据进行深度分析和挖掘,进而能够更加精准的评估用户的刷牙行为变化情况。
电量检测模块1602与主控模块101连接,电量检测模块1602根据控制信号检测主控模块101的电量并得到电量检测信号,通过该电量检测信号即可实时检测主控模块101的剩余电量情况,以确保控制电路10能够得到持续、稳定的电能。

作为一种可选的实施方式,图18示出了本发明实施例提供的电量检测模块1602的电路结构,详述如下:
如图18所示,电量检测模块1602包括:第十二电容C12、第二十七电阻R27、第二十八电阻R28以及第二十九电阻R29;其中,第十二电容C12的第一端和第二十七电阻R27的第一端共接于主控模块101,用于接入控制信号和电源信号BAT,第十二电容C12的第二端和第二十九电阻R29的第一端共接于地GND,第二十七电阻R27的第二端和第二十九电阻R29的第二端共接于第二十八电阻R28的第一端,第二十八电阻R28的第二端接主控模块101,用于将电量检测信号传输至主控模块101;因此电量检测模块1602通过接入的电源信号BAT检测得到电量检测信号,通过电量检测信号即可实现对于主控模块101的电量监控,保证控制电路10的正常工作。
通过本发明实施例,上述智能牙刷的控制电路10对于各个功能模块所采集的数据同时具有两种处理方式:1、主控模块101将用户的口腔数据上传至云端服务器30中,由于该口腔数据包括了用户在日常刷牙过程中所产生的刷牙数据,通过在云端服务器30中对口腔数据进行大数据处理分析后,即可实时监控用户的日常刷牙信息以及用户的牙齿健康变化情况,增强了用户的真实智能体验感;2、主控模块101根据用户的口腔数据生成控制信号,该控制信 号包含用户的全方位的刷牙行为信息,在用户刷牙的过程中,刷头模块102、位置检测模块103、压力检测模块104、电机驱动模块1001以及指示灯模块1002等根据该控制信号同步地向用户发出刷牙行为引导和提示纠正信息,实现了对于刷头类型、刷牙姿态数据以及刷牙压力数据的分类检测,实时监控用户的刷牙行为;同时智能终端20根据该控制信号可实时显示用户的刷牙行为,用户可直观地了解自己的刷牙动态信息以及口腔健康状态,进而使用户始终能够保持最佳的刷牙状态,全面地保护用户的口腔健康;从而有效地解决了现有技术中智能牙刷控制电路无法对于用户的刷牙数据进行大数据分析和处理,导致无法及时地保护用户的口腔健康的问题。

图20示出了本发明实施例提供的刷牙行为的智能监控方法的实现流程,其中该智能监控方法可应用于上述智能牙刷190、及其相互网络连接的智能终端20和云端服务器30中,下面结合图1-图20来说明该智能监控方法具体步骤,如下所述:
步骤S2001:在用户刷牙时,智能牙刷190获取用户的口腔数据,所述口腔数据包括刷头类型、刷牙姿态数据以及刷牙压力数据。
具体的,由于在上述智能牙刷的控制电路10包括刷头模块102、位置检测模块103以及压力检测模块104,因此,该智能牙刷190可实时获取用户的口腔数据,其中该口腔数据包含用户在刷牙过程中所产生的不同类型的刷牙数据。
步骤S2002:智能牙刷190将口腔数据传输至智能终端20。
步骤S2003:智能牙刷190和/或智能终端20根据口腔数据向用户发出刷牙行为指导信号。
由于口腔数据包括了用户在使用智能牙刷进行刷牙的过程中所检测得到一切数据,智能牙刷190和/或智能终端20对该口腔数据进行处理后即可得到用户的刷牙行为信息以及口腔健康状态,因此,智能牙刷190和/或智能终端20根据口腔数据向用户发出刷牙行为指导信号,通过该刷牙行为指导信号可实时指导用户的刷牙行为,从而全方位地保护用户的口腔健康。
步骤S2004:智能终端20将口腔数据上传至云端服务器30。
具体的,智能牙刷190与智能终端20之间可通过无线蓝牙通讯,因此智能牙刷190可将该口腔数据通过无线蓝牙传输至智能终端20;与此类似,智能终端20与云端服务器30可进行无线蓝牙双向信号传输,即智能终端20可将口腔数据通过无线蓝牙上传至云端服务器30。
步骤S2005:云端服务器30对口腔数据进行分析处理得到用户的刷牙行为信息。该刷牙行为信息可以是包含用户当前口腔健康状况、刷牙行为习惯等的刷牙行为信息,也可以是根据用户当前刷牙行为信息、口腔健康状况、刷牙行为(不良)习惯加以矫正后的得到的刷牙行为信息。
步骤S2006:根据所述刷牙行为信息监控用户的刷牙行为。
具体的,云端服务器30中提前存储数据处理分析算法,此时云端服务器30作为一个大数据平台,接收由智能终端20所传输的口腔数据,根据数据处理分析算法对口腔数据进行分析处理后即可得到用户的刷牙行为信息,通过该刷牙行为信息可反映用户的历史刷牙动作以及口腔健康状况;通过该刷牙行为信息即可记录用户的历史刷牙信息,评估用户的刷牙健康状况,也可通过该刷 牙行为信息预测用户的将来口腔健康状况,进而全面地智能监控用户的刷牙行为。
需要说明的是,在智能监控方法的实现流程中,步骤S2003与步骤S2006并没有先后的顺序关系,即步骤S2003既可以在步骤S2006之前,也可以在步骤S2006之后。
图21示出了在上述智能监控方法的实现流程中步骤S2003的具体操作方法,如下所示:
步骤S20031:智能牙刷190根据口腔数据生成控制信号。
步骤S20032:智能牙刷190和/或智能终端20根据控制信号向用户发出刷牙行为指导信号。
具体的,由于口腔数据包括用户在刷牙过程中所产生的所有刷牙数据,智能牙刷190根据用户的口腔数据生成控制信号,通过该控制信号即可全面评价用户的刷牙行为信息;当智能牙刷190根据用户的口腔数据生成控制信号后,一方面,智能牙刷190中内部的各个功能模块基于该控制信号分别向用户发出刷牙行为指导信号,如刷牙压力指导信息、刷牙姿态指导信息等,通过智能牙刷所发出的刷牙行为指导信号即可同时纠正用户在刷牙行为以及向用户发出刷牙提示信息;另一方面,当智能牙刷190将控制信号传输至智能终端20时,智能终端20即可根据该控制信号向用户发出刷牙行为指导信号,即安装在智能终端20上的APP即可基于该控制信号动态显示用户的刷牙行为以及口腔健康状态;从而用户可更加直观地、全方位地了解自己的刷牙行为状态,保证用户始终处于最佳的刷牙状态。
通过本发明实施例,在上述刷牙行为的智能监控方法中,通过智能牙刷190实时获取用户的口腔数据后,一方面,智能牙刷190将该口腔数据通过智能终 端20上传至云端服务器30中,由于云端服务器30中提前存储数据处理分析算法,基于该数据处理分析算法对口腔数据进行分析处理后即得到了用户的刷牙行为信息,该刷牙行为信息可用于评价用户的刷牙动作以及口腔健康状况;另一方面,智能终端20和/或智能牙刷190根据该口腔数据向用户发出刷牙行为指导信号,基于该刷牙行为指导信号即可在用户进行刷牙的过程中,同步地向用户发出刷牙行为引导和提示信息,以纠正用户的刷牙行为;同时用户还可通过智能终端20直观地了解自己的刷牙行为以及口腔健康状况;从而通过上述刷牙行为的智能监控方法实现了对于用户的口腔数据的深度分析和处理、以及基于口腔数据向用户实时发出刷牙行为指导和提示信息,极大地提高了用户的智能体验感;有效地解决了现有技术缺乏对刷牙数据进行深度处理和分析、以及用户的智能体验感极低的问题。
