波长为 200-280nm的紫外光能够对助听器进行消毒杀菌， 尤其是中心波长 为 254nm的紫外光很容易被生物体吸收， 作用于生物体的 DNA和 RNA, 使之被破 坏而导致细菌、 病毒死亡， 高强度的紫外光在短时间内即可杀菌， 对细菌繁殖 体仅需 1秒即可杀灭， 紫外光近距离高强度照射， 可将物体表面上的细菌芽孢 杀灭 99. 9%以上， 而且对任何细菌、病毒都有极强极高的杀菌消毒作用。波长为 160-200nm的紫外光能够与空气作用产生臭氧，尤其是中心波长为 185nm的紫外 光与空气作用产生具有强氧化作用的臭氧， 改变、 破坏微生物的 DNA、 靈等， 使细菌的代谢和繁殖过程遭到破坏， 从而杀灭细菌。 第一紫外光管 8和第二紫 外光管 10的双重杀菌作用使得消毒杀菌更加彻底。 优选第一紫外光管 8和第二紫外光管 10均设在收容腔 6的内壁上。
本实施例优选壳体 2内设置有透光搁板 12， 透光搁板 12可采用石英玻璃、 氟化钙等材料制成， 第一紫外光管 8和第二紫外光管 10中的至少一个位于透光 搁板 12的下方， 本实施例优选第一紫外光管 8设在透光搁板 12的下方， 产生 的紫外光可穿过该透光搁板 12， 对助听器进行消毒杀菌。 进一步优选透光搁板 12上设置有透气孔 14， 透光搁板 12的下方还设置有干燥装置， 干燥装置产生 的热气可沿透气孔 14向上走， 便于干燥放置在透光搁板 12上的助听器， 可抑 制细菌的繁殖。 当然， 还可以采用另外一种结构， 就是在壳体 2内设置有带透 气孔的搁板， 搁板的下方设置有干燥装置， 可抑制细菌的繁殖， 同时紫外光可 杀菌， 为了进一步实现紫外光的透射， 可优选搁板为透光搁板， 将第一紫外光 管 8和第二紫外光管 10中的至少一个位于搁板的下方， 实现助听器的 360° 全 方位消毒， 此结构与图 2相同。
还包括安全开关 16， 安全开关 16由壳盖 4的开合实现导通或切断。安全开 关 16的设置能够避免紫外光灼伤眼睛和皮肤， 充分保护使用者的安全。 优选安 全开关 16为霍尔开关， 可在壳盖 4的内壁上设置磁铁 18， 壳盖 4关闭时磁铁 18紧邻安全开关 16， 在打开壳盖 4时， 安全开关 16会切断第一紫外光管 8和 第二紫外光管 10的电源， 第一紫外光管 8和第二紫外光管 10熄灭， 从而充分 保护使用者的安全， 避免灼伤眼睛和皮肤。 安全开关 16并不局限于霍尔开关， 也可以为压力开关， 可将压力开关设在壳体 2内， 壳盖 4关闭时接触压力开关， 壳盖 4打开时， 压力消失， 存在压力的改变， 实现对第一紫外光管 8和第二紫 外光管 10的导通或切断。
优选收容腔 6的至少一个内壁上设有镜面反射层 20， 紫外光可直接辐射和 反射至助听器， 提高了紫外光的辐照强度和辐照范围， 消毒杀菌效果好。 进一 步优选镜面反射层 20可以为镜片、 金属镜面贴片、 反光膜或电镀层， 镜片可以 是玻璃镜子； 金属镜面贴片可以是不锈钢板。
如图 4所示， 为了抑制细菌的繁殖， 同时避免助听器受潮而损坏， 还可以 在壳体 2内设有干燥装置， 干燥装置包括电源电路 22、 主控电路 24、 温度采集 电路 26、 键控电路 28、 复位电路 30和干燥电路 32。 优选第一紫外光管 8、 第 二紫外光管 10以及安全开关 16均与电源电路 22和主控电路 24连接。
电源电路 22由适配器提供 +5V直流电源， 供各电路用电。其包括 USB端口， 以方便就近从电脑或手机充电器获取 +5V电源。 二极管 VD起极性保护作用， C1 为滤波电容。 二极管 VD的正极与 USB端口的电源引脚连接， 二极管 VD的负极 与滤波电容 C1的正极连接， 滤波电容 C1的负极与 USB端口的接地引脚连接。
主控电路 24采用 ATmega8单片机 U1作主控 MCU， 12MHz晶振 G以满足控制 速度及实时性。
温度采集电路 26包括多个温度传感器，优选温度传感器的型号为 DS18B20 , 分别为 STl-STn。 STl-STn 的电源地脚 GND接在一起， 电源输入端 Vcc接在一起 且与电源电路 20提供的 +5V直流电源连接，数字信号输入输出端 DQ接在一起且 与单片机 U的 PD2口连接。 DS18B20与单片机 U1之间仅需一条口线即可双向通 信， 而且在一条总线上可挂接多个 DS 18B20温度传感器， 实现多点组网测温， 测温精度高。 实际应用中不需任何外部元器件， 也不需进行 A/D转换， 即可直 接输出数字温度信号。本实施例的电路中包括两个 DS18B20温度传感器 ST ST2 , 此时 n=2，设置了两处测温点， 但并不局限于两处测温点， 也可以设置三个、 四 个等 DS 18B20温度传感器。
键控电路 28包括 SB1， SB1—键多功能。 按一次， 定时 2h， 可连续加热 2 小时； 按二次， 定时 4h， 可连续加热 4h; 按三次， 定时 6h， 可连续加热 6小时。 内设定三次为一循环周期， 按第四次进入下一个循环周期， 按第四次为定时 2h， 按第 5次为定时 4h， 按第 6次为定时 6h， 如此循环不断。 长按 SB1 , 则设置取 消， 关机。
复位电路 30包括 C2和 Rl， 系统上电自动复位。 刚开始上电时， 亦即刚一 接通 Vcc电源时， 由于电容 C2上的电压不能突变， 通电瞬间 C2相当于短路， Vcc电源的电压都落在 R1上， 此一高电平加在单片机 U的 PC6/RST口， 只要满 足加在 RST上的高电平能持续 24个振荡周期即可使单片机复位。
干燥电路 32包括至少两组独立工作的发热元件 Rfz l-Rfzn、 至少两个三极 管 VTl-VTn , 每组发热元件的多个发热元件并联连接， n为大于或等于 2的正整 数， 每组发热元件并联后的一端与 +5V直流电源连接， 另一端与对应的三极管的 发射极连接， 每个三极管的基极与主控电路 24连接， 集电极与地连接。 本实施 例优选干燥电路 32包括三组独立工作的发热元件、 分别与三组发热元件连接的 三个三极管 VT1、 VT2、 VT3， 三组发热元件均敷贴在壳体 2内的 PCB板 34上， 三组发热元件间隔排布在 PCB板 34上， 每组发热元件均匀分布， 发热元件散发 的热气可沿透气孔 14向上走， 助听器放置在透光搁板 12上被干燥。 优选三组 发热元件分别包括 A、 B、 C三组， 如图 3所示， A组发热元件包括 5个 Rfz l ， B组发热元件包括 8个 Rf z2 ， C组发热元件包括 12个 Rfz3， 5个 Rfz l并联后 一端与 +5V直流电源连接， 另一端与三极管 VT1的发射极连接， 8个 Rfz2并联 后一端与 +5V直流电源连接， 另一端与三极管 VT2的发射极连接， 12个 Rfz3并 联后一端与 +5V直流电源连接，另一端与三极管 VT3的发射极连接，三极管 VT1 、 VT2 、 VT3的基极分别与单片机 U1的 PB1口、 PB2口、 PB3口连接， 三极管 VT1、 VT2 、 VT3的集电极均与地连接。 干燥电路 32设置 3个加热区， 由单片机发出 指令， 实现分时段、 分区段交替、 交叉、 迭加加热， 从而保持消毒装置的温度 恒定。 单片机发出指令， PB1口、 PB2口、 PB3口低电平使三极管 VT1 、 VT2 、 VT3导通， Rfz l 、 Rfz2 、 Rfz3得电发热； PB1口、 PB2口、 PB3口高电平时， 三极管 VT1 、VT2 、VT3截止， Rfz l 、 Rf z2 、 Rf z3失电停止发热。 Rf z l 、 Rf z2 、 Rfz3均采用贴片式 PTC线性热敏电阻， 密集型阵列式布局， 发热点多、 密、 细， 分布广不存在死角， 具有发热均匀、 升温快的特点， 由于贴片式线性热敏电阻 是由 PTC材料制成具有正温度系数， 当热敏电阻通过电流发热时温度升高， 其 电阻相应增大， 使通过的电流相应减小， 于是发热量也相应减小， 温度相应下 降而处于恒温状态， 具有自动调控温度的性能。
分区域是将发热元件的排列分布位置划分成若干个区域； 分时段则是将整 个加热干燥过程切割成若干个时段。
现以定时 4h、 三区域、 三时段为例说明：
消毒杀菌装置定时启动开始工作至升温到内设定温度上限为升温阶段， 此 升温过程需时 20分钟。 其后至定时工作 1小时之间为保温第一时段； 第一保温 时段后至定时工作 2小时之间为第二保温时段； 第二保温时段后至定时结束为 第三保温时段。 图 2为本实施例的三区域的划分示意图： A区域有 5个发热元件 Rfzl , B区域有 8个发热元件 Rfz2， C区域有 12个发热元件 Rfz3。 以上安排是 基于发热元件均布、发热均匀的原则。 A区域的发热元件最少是因为 A区域工作 在保温第一时段， 余热最大。
分区域、 分时段交替、 交叉、 迭加加热是一种全新的智能加热。 区域、 时 段分的越细则加热温度越恒定， 同时， 区域、 时段的组合视需要可任意组合。
第一紫外光管 8、 第二紫外光管 10、 电子镇流器 AP1、 三极管 VT形成消毒 电路 36， 受控于单片机 U1的 PC3口。 PC3口高电平时， 电子镇流器 API点亮第 一紫外光管 8和第二紫外光管 10， 发出紫外光， 实现双重杀菌作用。 安全开关 16通过反相器 IC输出信号给单片机 U1的 PD3口， 实现对第一紫外光管 8和第 二紫外光管 10的电源的导通或切断。
另外， 为了便于知道干燥定时时间和检测助听器的电量， 还可以设置显示 电路 38和电池检测电路 40。 显示电路 38采用点阵液晶模块 LCD, 可以显示文字、 符号和图形。 A、 时间 显示： 定时设定时间， 分 2h、 4h、 6h; 定时启动时刻， 24小时制； 即时时间， 24小时制， 逐秒递增。 B、 温度显示： 即时温度。 C、 电量显示： 电池图形为空 格时， 文字显示电池失效； 电池图形有一格时， 文字显示欠电； 电池图形有二 格时， 文字显示电量不足； 电池电量为三格满格时， 文字显示电量充足；
电池检测电路 40利用 ATmega8单片机 U1内部的模数转换器 ADC检测电池 电压的高低来判断电池的好坏。单片机 ATmegaS提供 6路逐次逼近型的 ADC, 其 中， ADC0-ADC3这 4个通道提供了 10位的转换精度， ADC4、 ADC5两个通道只提 供 8位的转换精度。 本电路利用 ADC0检测电压的高低。 测试时， 只要将电池置 于壳体 2的检测凹槽 42内， 推紧使之与检测凹槽 42内的极片 （图中未示出） 接触良好， 极片具有正极、 负极， 极片的正极与单片机 U1的 PC0口连接， 负极 接地， 即可知电池的好坏。 检测结果由 LCD以图形和文字显示， 分 4种状态： 电池图形为空格时， 文字显示电池失效； 电池图形有一格时， 文字显示欠电； 电池图形有二格时， 文字显示电量不足； 电池电量为三格满格时， 文字显示电 量充足。
工作过程：
助听器放置在透光搁板 12上， 接通电源， 系统上电自动复位，进行初始化。 连续按动 SB1定时时间选择按钮 2次， 定时启动， LCD显示定时时间 4h、 定时 启动时刻 XX： XX以及即时时间 XX： XX逐秒递增。 同时， DS18B20 温度传感器采 集温度数据并将数据从总线传送给单片机 U经单片机 U处理， 与预设温度比较， 结果远远低于下限阈值， 启动优先程序， 单片机 PB1口、 PB2口、 PB3输出低电 平， 驱动干燥电路 32所有加热区同时加热升温， 直至 DS18B20采集到的温度数 据已达到预设定温度上限阈值时， 单片机 U1发出指令， PB2口、 PB3口输出高 电平关断干燥电路 32的 B加热区和 C加热区。 整机进入第一保温时段， 仅由 A 加热区进行补偿加热， 以保持温度恒定。 进入保温第二时段单片机 PB1 口输出 高电平关断 A加热区， PB3口输出低电平开通 C加热区加热保温。进入保温第三 时段单片机 PB3口输出高电平关断 C加热区， PB1口、 PB2口输出低电平开通 A 加热区和 B加热区补充加热直至定时 4h结束。 同时， 设定加热全过程中进行二 次杀菌消毒， 分别在进入第一保温时段和第二保温时段时自动启动工作， 第一 紫外光管 8和第二紫外光管 10分别发出 254皿的紫外光、 185皿的紫外光， 产 生的紫外光可经镜面反射层 20直接辐射和反射至助听器， 辐照强度和辐照范围 大， 杀菌消毒彻底， 每次十分钟后自动熄灭。 另外， 在打开壳盖 4 时， 安全开 关 16会将信号传递至单片机 Ul， 单片机 U1转入紧急中断程序切断第一紫外光 管 8和第二紫外光管 10的电源， 第一紫外光管 8和第二紫外光管 10熄灭， 从 而充分保护使用者的安全。
在加热干燥过程中如果探测到低于预设定温度时， 会自动中断原有保温程 序而优先进入补充加热程序， 直至升温至预设定温度时， 自动退出优先补充加 热程序恢复继续保温程序。 当探测到高于预设定温度时， 会中断保温程序而优 先进入切断发热元件供电的紧急程序， 待温度降至预设定温度时会自动退出紧 急程序恢复继续保温程序。
以上依据本发明的理想实施例为启示， 通过上述的说明内容， 相关人员完 全可以在不偏离本项发明技术思想的范围内， 进行多样的变更以及修改。 本项 发明的技术性范围并不局限于说明书上的内容， 必须要根据权利要求范围来确 定技术性范围。
