具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
需要说明，本发明实施例中所有方向性指示（诸如上、下、左、右、前、后……）仅用于解释在某一特定姿态（如附图所示）下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
另外，在本发明中涉及“第一”、“第二”等的描述仅用于描述目的，而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。另外，各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本发明要求的保护范围之内。
本发明提出一种破壁机。
参照图1及图2，在本发明实施例中，该破壁机包括杯盖1、搅拌杯2、及底座3，所述破壁机还包括温度检测电路100、控制电路200、电磁阀300、加热装置（图中未示出）、及排气塞4。
所述加热装置，对搅拌杯2内的物体进行加热；所述温度检测电路100，对搅拌杯2内的温度进行采样；在所述温度检测电路100检测到搅拌杯2内的温度超过预设温度阈值时，所述控制电路200控制所述电磁阀300通电，以开启所述排气塞4释放搅拌杯2内气体。
需要说明的是，在利用破壁机制作豆浆、米糊等食材时，在沸腾后会产生泡沫，很容易溢出。在泡沫快要溢出时，如果打开盖子，泡沫遇到较冷空气，由于压差会导致泡沫很快破掉，则不会溢出。本发明采用这个原理来防泡沫溢出。
在搅拌杯2内温度超过设定温度阈值时，即达到沸腾温度时，控制电路200控制电磁阀300上电，进而电磁阀300开启排气塞4，释放搅拌杯2内的高温气体，从而消除泡沫。
本发明技术方案通过设置底座3、搅拌杯2、及杯盖1、温度检测电路100、控制电路200、电磁阀300、加热装置、及排气塞4，形成了一种破壁机。在对搅拌杯2内的物体进行加热时，所述温度检测电路100对搅拌杯2内的温度进行实时检测；在检测到搅拌杯2内的温度超过预设温度阈值时，该温度阈值可设为沸腾温度，此时搅拌杯2内容易出现泡沫溢出，通过电磁阀300开启排气塞4，使得泡沫接触外部较冷的空气，从而除去泡沫，有效防止搅拌杯2内的泡沫溢出。
进一步地，在所述温度检测电路100检测到搅拌杯2内的温度超过预设温度阈值时，所述控制电路200控制所述加热装置进行间歇性加热，所述控制电路200还控制所述电磁阀300保持通电，以控制所述排气塞4保持开启。
例如在制作豆浆时，破壁机先通过加热装置进行全功率加热，温度检测电路100检测到达到沸腾阶段时，再进入间歇性加热阶段，例如控制电路200控制加热4秒，再停止加热6秒，从而减少电能损耗。在间歇性加热阶段，控制电路200控制电磁阀300保持上电，使排气塞4保持开启，搅拌杯2内与外界空气可以接通，避免产生泡沫。
进一步地，所述破壁机还包括电机5及搅拌刀6，所述电机5设置于底座3，所述搅拌刀6设置于搅拌杯2的底部；所述电机5及搅拌刀6均设有相互卡合的卡合部，将所述搅拌杯2放置于底座3时，所述电机5与所述搅拌刀6卡合。
易于理解的是，电机5转轴上设有卡合部，对应的搅拌刀6上也设有卡合部，在将搅拌杯2放置于底座3上时，电机5转轴与搅拌刀6卡合，当电机5上电后，便带动搅拌刀6旋转。
所述控制电路200在加热超过预设时间后，加热阶段完成，进入搅拌阶段，控制电路200控制所述电机5通电；所述电机5带动所述搅拌刀6对搅拌杯2内的物体进行搅打。
进一步地，所述搅拌刀6对物体进行搅打时，所述控制电路200还控制所述电磁阀300断电，以关闭所述排气塞4，以防止在进行搅打时，搅拌杯2内的液体通过排气塞4溢出。
易于理解的是，在不同的海拔高度，其沸腾温度不一样，因此所述预设温度阈值根据所述破壁机所在海拔高度进行设定。
具体地，所述杯盖1上开设有贯穿所述杯盖1的安装孔（图中未标出），所述排气塞4安装于所述安装孔；所述排气塞4内部为中空结构，且所述排气塞4的中空结构与搅拌杯2相连通；所述排气塞4周侧设有多个透气孔7；其中，
在所述电磁阀300通电时，电磁阀300推动排气塞4向外侧移动，露出透气孔7；在所述电磁阀300断电时，所述排气塞4回复至初始状态。
本实施例中，安装孔为圆孔，还可为方形孔等，此处不一一列举。排气塞4内部中空，形成了容纳空间，该容纳空间与搅拌杯2连通。排气塞4与安装孔紧密配合，该排气塞4与安装孔的孔壁相接触的侧面设有多个透气孔7，当排气塞4被电磁阀300推动时，排气塞4的透气孔7露出，使得外部与搅拌杯2内部连通。
在电磁阀300断电时，排气塞4下降，排气塞4上的透气孔7被安装孔堵住，使得外部与搅拌杯2内部隔离。
本实施例中，所述加热装置采用电磁加热。加热装置的电磁加热线圈（图中示出）设置于底座3上，该电磁加热线圈与控制电路200电连接。此外，加热装置还可采用加热管进行加热，当采用加热管进行加热时，加热管设置于搅拌杯2的内部。
进一步地，所述破壁机还包括对插端子（图中未标示），所述对插端子包括公端子8和母端子9，所述公端子8设置于底座3，所述母端子9设置于搅拌杯2；所述公端子8分别与所述电机5、控制电路200电连接；所述母端子9分别与所述温度检测电路100、电磁阀300电连接。
本实施例中，具体地，所述破壁机包括热敏电阻Rt、第一电容C1、第一二极管D1、第二二极管D2、第一电阻R1、第二电阻R2、第二电容C2、控制芯片U1、第一三极管Q1、限流电阻Rs、第一电源VCC1及第二电源VCC2。
其中，热敏电阻Rt的第一端与所述第一电源VCC1连接，热敏电阻Rt的第二端经所述第一电容C1接地；所述第一二极管D1的阳极与所述第一电源VCC1连接，所述第一二极管D1的阴极与所述第二二极管D2的阳极连接，所述第二二极管D2的阴极接地；所述第一电阻R1并联于所述第二二极管D2的两端；所述第二电阻R2的第一端与所述第二二极管D2的阳极连接，所述第二电阻R2的第二端与所述控制芯片U1的检测端TEMP连接；所述控制芯片U1的驱动端DRI与所述第一三极管Q1的基极连接，所述第一三极管Q1的发射极接地，所述第一三极管Q1的集电极经所述限流电阻Rs与所述电磁阀300的一端连接；所述电磁阀300的另一端与所述第二电源VCC2连接。
本实施例中，第一电源VCC1输出电压为5V（伏特），第二电源VCC2输出电压为18V。所述热敏电阻Rt与所述第一电容C1构成所述温度检测电路100；
第一二极管D1、第二二极管D2、第一电阻R1、第二电阻R2、第二电容C2构成滤波稳压电路400，用于对输入的温度采样信号进行滤波稳压。
本实施例中，所述控制芯片U1采用8位单片机实现，构成控制电路200；
所述第一三极管Q1及限流电阻Rs构成开关电路500，用于根据控制芯片U1输出的电平信号控制电磁阀300的通电或断电，从而开启或关闭所述排气塞4。
第一电容C1、第一二极管D1、第二二极管D2、第一电阻R1、第二电阻R2、第二电容C2、控制芯片U1、第一三极管Q1、限流电阻Rs、第一电源VCC1及第二电源VCC2设置于PCB主控板10上，PCB主控板10则设置于底座3；热敏电阻Rt则设置于搅拌杯内部。
本发明技术方案通过在搅拌杯2内的温度达到沸腾温度时，控制电磁阀300通电，使得搅拌杯2内与外部空气连通，利用压差出去泡沫，从而防止了泡沫溢出，避免了使用者用手去打开杯盖1而造成烫伤。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
