下面对照附图并结合优选的实施方式对本发明作进一步说明。
实施例 1
如图 1所示的暖奶器， 包括暖奶器底部的发热单元 （图 1中未示出）， 还包 括位于暖奶器内壁上的红外测温模块 10和保温圈 20， 所述保温圈 20的孔用以 供奶瓶放入， 且保温圈 20具有一定的弹性， 其外径不小于暖奶器内腔的直径， 内径较小， 小于市场上现有常规奶瓶的瓶身直径， 以适用更多的奶瓶， 如图 2 所示， 保证奶瓶放入暖奶器后， 奶瓶壁与暖奶器内壁之间于保温圈 20以下形成 密封空腔 50以阻挡热量散失， 红外测温模块 10位于所述密封空腔 50之外， 且 红外测温模块的视场在保温圈 20与暖奶器口之间的空间内， 保证其视场不被热 气流所影响， 即所述视场内，奶瓶壁与暖奶器内壁之间的空间的温度不会高于奶 说明书 瓶壁的温度， 红外测温模块 10不会误测， 例如： 在没有保温圈的情况下， 热量 散失， 与空气对流， 在红外测温模块的视场内： 奶瓶与暖奶器内壁之间形成温度 高于奶瓶的热气流，会导致红外测温模块测得的温度是热气流的温度， 而非奶瓶 的温度。 另， 由于密封空腔 50的形成阻挡了热量散失， 来自于暖奶器底部的热 量几乎全用于加热奶瓶， 奶瓶与奶水进行热交换， 红外测温模块 10能够获得较 准确的奶水温度。
进一步地， 本实施例的暖奶器还包括指示模块， 如图 3和图 5所示， 所述指 示模块包括三个不同颜色的指示灯， 可以是 LED灯， LED1红色、 LED2绿色、 LED3蓝色； 还具有一个输入端耦接至红外测温模块 10的输出端， 该输入端的 输入电压 Vt， 即为红外测温模块 10测得的温度 T所对应的电压值， 其中温度值 和电压值之间的转换已为公知技术， 在此不再赘述。 如图 5， Vcc可以是 5V或 者 12V， 根据 Rl、 R2、 R3、 R4的电阻值设置， 获得电压 VI和电压 V2， 分别 对应两个温度阈值， 优选为 VI对应第一阈值 45°C， V2对应第二阈值 37°C， 即 V1>V2。 当红外测温模块 10测得的温度 T>45°C， 即当 Vt>Vl时， 比较器 C1输 出 Vcc， C2输出 0， 仅 LED1导通， 即此时指示灯发出红色； 当1^<37 ， 即当 V V2时， 比较器 C1输出 0， C2输出 Vcc， 仅 LED3导通， 即此时指示灯发出 蓝色； 当 37°C T 45°C， 即 V2 Vt Vl时， 比较器 C1和 C2均输出 0， 由于 反相器 （非门） NOT的作用， 能将 LED2导通， 且仅有 LED2导通， 即此时指 示灯发出绿色。夜间， 用户能够通过上述指示灯的不同颜色， 直观地分辨出奶瓶 处于何种温度范围。
进一步地， 见图 1， 本实施例的暖奶器还包括位于暖奶器奶瓶放置腔底部的 自动开关 70， 所述自动开关 70与发热单元电连接， 具有第一工作状态和第二工 作状态，当暖奶器中没有奶瓶时，工作于第一工作状态；当暖奶器中放有奶瓶时， 自动开关 70受重力按压而进入第二工作状态。如图 4所示， 自动开关 70即为图 4中的开关8。 所述暖奶器还包括设于其外壳上的调温模块 （图中未示出） 和显 示模块（图中未示出）， 所述调温模块可以使用 "+ "和 "―"按键调温， 也可以 使用调温旋钮， 在本实施例中， 所述调温模块使用调温旋钮， 所述显示模块包括 液晶显示屏或 LED显示板。 所述调温模块耦接至所述发热单元和显示模块， 如 图 4所示， 用户通过调温旋钮来调节可调电阻 Rp， 实现温度设定。 所述显示模 说明书 块耦接至所述自动开关 70和红外测温模块， 当用户设定温度后， 显示模块显示 设定温度一定时间 （例如可以是 20秒） 后， 显示红外测温模块测得的温度。 该 显示模块的温度显示方法已为公知技术， 在此不再赘述。 当奶瓶放入暖奶器， 自 动开关 70进入第二工作状态， 即图 4中的开关 S闭合： 显示模块开始进行显示， 红外测温模块 10首次测温，测得的温度转换成电压值 Vt输入图 4中的比较器 C 的正向输入端， 与反向输入端的电压（即设定温度对应的电压值）进行比较， 若 测得的温度大于等于所述设定温度， 即 Vt大于等于 Rp有效电阻两端的电压， 则比较器 C输出 Vcc， 此时继电器 K不会导通， 则 PTC发热片不会发热； 若测 得的温度小于所述设定温度， 贝 ij比较器 C输出为 0V， 继电器 K导通， 线圈产生 电磁力， 其触点开关由触点 P1转到触点 P2， PTC发热片通电开始发热； 此后所 述红外测温模块 10实时测温或间歇测温， 优选进行间歇测温 （例如每隔一分钟 测一次温度）， 并把每一次测得的温度反馈到所述显示模块、 发热单元和指示模 块， 以分别进行显示、调整所述发热单元发热片的工作状态、 使指示模块的指示 灯 30发出不同的颜色， 当测得的温度大于等于所述设定温度时， 所述发热单元 的 PTC发热片停止发热， 当测得的所述温度小于所述设定温度时， 所述发热单 元的 PTC发热片恢复发热；
当奶瓶从暖奶器取出后， 所述自动开关 70弹起而进入第一工作状态， 即开 关 S断开： 所述显示模块和指示模块均关断， 所述发热单元的 PTC发热片停止 发热， 所述红外测温模块 10停止测温。
更进一步地， 本实施例的暖奶器还包括设于暖奶器外壳上的照明灯 60， 见 于图 1， 所述照明灯 60与一延迟开关模块电连接， 见于图 3。 如图 6所示： 灯 Li即为所述照明灯 60， 该延迟开关模块的原理图： 包括一延时继电器 Kl， 三极 管 Ql、 Q2以及电容5。 开关 S对应所述的自动开关 70， 当自动开关 70处于第 二工作状态中时， 三极管 Q1和 Q2均不导通； 当自动开关 70由第二工作状态进 入第一工作状态， 即开关 S由闭合到断开时， 三极管 Q2先于 Q1导通， Q2导通 时， 继电器 K1线圈产生电磁力， 弹片被吸合至触点 P3， 照明灯 Li被点亮。 当 电容 E充满电 （Q2导通 1秒左右） ， Q1便导通， Q2截止， 由于继电器 K1为 延时继电器， 弹片仍在触点 P3处， 当延时时间用完后， 弹片由 P3回到 P4， 照 明灯 Li熄灭。 实现所述的延迟开关的功能， 使照明灯仅在开关 S (自动开关 70) 说明书 由第二工作状态进入第一工作状态时点亮， 且延迟一段时间后自动熄灭；
上述延迟开关模块的实现方式还可以如图 7所示：与图 6不同的是，根据电 容 E1和电阻 Rx的值设定延迟时间， 且继电器 K2并非延时继电器， 而是一般的 继电器。图 7中，当自动开关 70处于第二工作状态中即开关 S接到 Vcc—端时， 三极管 Q3、 Q4均截止， 照明灯 Li不会亮， 电容 E1得以充电。 当自动开关 70 进入第一工作状态即开关 S接到电阻 Rx—端时， 电容 E1放电以使三极管 Q3 和 Q4导通， 继电器的弹片由 P6被吸合至 P5， 照明灯 Li得以点亮， 当电容 E1 放完电后，继电器 K2的线圈中不再有电流，弹片由 P5回到 P6，照明灯 Li熄灭， 实现延迟功能， 使照明灯仅在开关 S (自动开关 70) 由第二工作状态进入第一工 作状态时点亮， 且延迟一段时间后自动熄灭。
优选地，所述红外测温模块嵌于暖奶器壁体内，测温探头可不突出于暖奶器 内壁， 以免阻挡奶瓶的放入， 其视场处于保温圈 20与暖奶器口所处平面之间的 空间内。
本实施例的暖奶器，使用红外测温模块来获取奶水温度，使用保温圈来阻挡 暖奶器内的热量与外界空气对流， 防止热量散失，保证热量全部用于加热奶瓶和 奶水， 也避免因热量散失而影响非接触式测温模块的视场，使非接触式测温模块 能够获得较准确的奶水温度。 实施例 2
如图 8所示的暖奶器， 其与实施例 1的暖奶器的区别在于： 保温圈 20并非 固定于暖奶器内壁上， 而是与暖奶器分开设置， 当使用时， 如图 9和图 10所示： 先把保温圈 20套于奶瓶 40上， 再将奶瓶放入暖奶器内， 效果图同图 2。 本实施 例 2的暖奶器与实施例 1的暖奶器不同之处还在于： 暖奶器内部工作电路模块， 其使用主芯片即图 11中所示的控制模块来控制发热元件、 照明灯、 非接触式测 温模块 （可使用红外测温模块）、 显示模块和指示灯来实现如实施例 1的功能， 调温模块用以供用户输入设定温度。 图 11中的感应模块的功能类似于图 3中的 自动开关 70， 用于感应奶瓶是否放入， 从而控制模块进行相应的控制， 所述感 应模块可以是红外感应或者是重力感应。
当奶瓶放入时， 感应模块给所述控制模块发送一信号 ON， 控制模块接收到 说明书 该信号 ON后， 启动显示模块、 红外测温模块和指示灯：
所述显示模块启动后显示默认设定温度 37°C， 当用户进行设定时， 再显示 用户输入的设定温度 Ts， 当显示设定温度一段时间 （例如 20秒） 后， 开始显示 红外测温模块测得的温度；
所述红外测温模块启动后，开始进行测温，将测得的温度反馈至所述控制模 块， 控制显示模块进行显示测得的温度， 并且将该温度与所述设定温度 Ts进行 比较， 若测得到温度大于等于设定温度 Ts， 则所述发热元件不发热； 若测得的 温度小于设定温度 Ts，则所述控制模块控制发热元件进行发热或者间歇发热（例 如隔一分钟发热一分钟）， 此后红外测温模块进行实时测温或者间歇测温 （例如 一分钟测一次）；
所述指示灯根据红外测温模块测得的温度来发出三种不同颜色：当测得的温 度大于第一阈值 45°C时， 发出红色， 当测得的温度小于第二阈值 37°C时， 发出 蓝色，当测得的温度介于第一阈值和第二阈值之间时，发出绿色。在奶瓶放入时， 指示灯默认发出绿色。
在优选方案中， 还包括照明灯， 当奶瓶取出时， 感应模块向控制模块发送一 个信号 OFF， 控制模块接收到信号 OFF, 关闭指示灯、 显示模块、 发热元件和 红外测温模块， 并且点亮照明灯， 且控制照明灯在点亮后一段时间（例如可以是 l~10min) 后熄灭， 在夜间时， 可以给用户喂奶提供照明。
应当注意的是，上述的第一阈值和第二阈值，可以是在暖奶器出厂前设定的， 也可以是用户通过调温模块进行设定的； 上述的调温模块可以是调温旋钮， 也可 以是键盘调温； 显示模块可以是液晶显示或 LED显示； 发热元件优选使用 PTC 发热片， 其恒温点可以根据实际需要制定。 以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能 认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的技术人员 来说， 在不脱离本发明构思的前提下， 还可以做出若干等同替代或明显变型， 而 且性能或用途相同， 都应当视为属于本发明的保护范围。
