为使本实用新型的目的、技术方案和优点更加清楚，下面将结合附图对本实用新型的实施方式作进一步地详细描述。
参考图1至图4，本实用新型提供一种加热器1，包括：加热芯体10、第一绝缘壳体20和第二绝缘壳体30。其中，加热芯体10包括位于加热芯体10的相反两侧的第一表面11和第二表面12。本实施例中，第一表面11和第二表面12位于加热芯体10的厚度方向(图1至图3中Z方向所示)的相反两侧。第一绝缘壳体20设于所述第一表面11，并与加热芯体10的所述第一表面11一起围成第一绝缘加热腔21。第二绝缘壳体30设于所述第二表面12，并与加热芯体10的所述第二表面12一起围成第二绝缘加热腔31。其中，所述第一绝缘加热腔21和所述第二绝缘加热腔31相连通。第一绝缘壳体20和第二绝缘壳体30与加热芯体10的连接方式不做限制，例如是通过螺栓与密封圈实现密封连接。
由于本申请中，加热器1采用第一绝缘壳体20和第二绝缘壳体30，从而形成了第一绝缘加热腔21和第二绝缘加热腔31。当使用加热器1加热流体(例如水)时，水在第一绝缘加热腔21和第二绝缘加热腔31中流通被加热的过程中，加热器1的绝缘性好，实现水电隔离，可防止漏电现象的发生，加热器1的安全性能得到提升。
需说明的是，第一绝缘壳体20和第二绝缘壳体30的材料不做限制，能够实现绝缘即可。例如，本实施例中，第一绝缘壳体20和第二绝缘壳体30均是塑料壳体。
在一些可能的实施方式中，继续参考图1至图4，加热器1还包括绝缘层16，所述绝缘层16包裹所述加热芯体10，使得加热芯体10绝缘，也即加热芯体10的第一表面11和第二表面12都是绝缘的。绝缘层16的类型不做限制，例如是包括聚酰亚胺薄膜绝缘层16。
所述第一绝缘壳体20面向所述第一表面11的一侧开口，所述第一绝缘加热腔21以所述第一表面11为底。即，第一绝缘壳体20的壳壁以及加热芯体10的第一表面11一起围成了第一绝缘加热腔21。所述第二绝缘壳体30面向所述第二表面12的一侧开口，所述第二绝缘加热腔31以所述第二表面12为底。即，第二绝缘壳体30的壳壁以及加热芯体10的第二表面12一起围成了第二绝缘加热腔31。
由于第一绝缘壳体20面向所述第一表面11的一侧开口，第二绝缘壳体30面向所述第二表面12的一侧开口，以及加热芯体10是绝缘的。从而，流入第一绝缘加热腔21中的流体能够与所述第一表面11上的绝缘层16充分接触，流入所述第二绝缘加热腔31中的流体能够与所述第二表面12上的绝缘层16充分接触，提升了加热腔中流体被加热的加热效率，热能利用率也高。
在一些可能的实施方式中，继续参考图1至图4。所述加热芯体10沿长度方向(图1至图4中X方向所示)延伸，加热芯体10的所述第一表面11和所述第二表面12位于所述加热芯体10的厚度方向(图1至图3中Z方向所示)的相反两侧。加热芯体10的所述第一表面11沿所述长度方向间隔设置第一压紧件111和第二压紧件112，沿所述厚度方向，所述第一绝缘壳体20分别与所述第一压紧件111和第二压紧件112相抵。可选地，第一压紧件111和第二压紧件112分别沿加热芯体10的宽度方向(图1和图2中Y方向所示)延伸。第一绝缘壳体20分别与所述第一压紧件111和第二压紧件112相抵后，可以提升第一绝缘壳体20与第一压紧件111和第二压紧件112的密封性。第一压紧件111和第二压紧件112例如是塑料压紧件。
在一些可能的实施方式中，所述第二表面12沿所述长度方向间隔设置第三压紧件121和第四压紧件122，沿所述厚度方向，所述第二绝缘壳体30分别与所述第三压紧件121和第四压紧件122相抵。可选地，第三压紧件121和第四压紧件122分别沿加热芯体10的宽度方向(图1和图2中Y方向所示)延伸。第二绝缘壳体30分别与所述第三压紧件121和第四压紧件122相抵后，可以提升第二绝缘壳体30与第三压紧件121和第四压紧件122的密封性。第三压紧件121和第四压紧件122例如是塑料压紧件。
本实施例中，是在第一表面11上第一压紧件111和第二压紧件112，以及在第二表面12上设置第三压紧件121和第四压紧件122。在一些可能的实施方式中，可以是在第一表面11上第一压紧件111和第二压紧件112。或者，在第二表面12上设置第三压紧件121和第四压紧件122。
如图3和图4所示，所述第一表面11上的第一压紧件111具有与所述第一表面11呈锐角设置的第一斜面1111(图3中示出第一压紧件111的侧面呈三角形状)，所述第一表面11上的第二压紧件112具有与所述第一表面11呈锐角设置的第二斜面1121(图3中示出第二压紧件112的侧面呈三角形状)。所述第一绝缘壳体20内设有与所述第一斜面1111平行且相抵的第三斜面(与第二绝缘壳体30中的第三斜面34的结构相同)，与所述第二斜面1121平行且相抵的第四斜面(与第二绝缘壳体30中的第四斜面35的结构相同)。沿长度方向，第一绝缘壳体20的第三斜面和第四斜面位于第一压紧件111的第一斜面1111和第二压紧件112的第二斜面1121之间。
一方面，在将第一绝缘壳体20安装于加热芯体10上时，可以起到安装引导的作用，方便安装。另一方面，将第一绝缘壳体20安装于加热芯体10上后，加热芯体10可以在长度方向对第一绝缘壳体20起到限位作用。再一方面，由于第一绝缘壳体20与第一压紧 件111和第二压紧件112是斜面配合，增大了相抵的接触面积，更好地提升第一绝缘壳体20与加热芯体10之间的密封性。
同样，所述第二表面12上的第三压紧件121具有与所述第二表面12呈锐角设置的第一斜面(图3中示出第三压紧件121的侧面呈三角形状，与第一绝缘壳体20中的第一斜面1111的结构相同)，所述第二表面12上的第四压紧件122具有与所述第二表面12呈锐角设置的第二斜面(图3中示出第四压紧件122的侧面呈三角形状，与第一绝缘壳体20中的第二斜面1121的结构相同)。所述第二绝缘壳体30内设有与所述第一斜面平行且相抵的第三斜面34，与所述第二斜面平行且相抵的第四斜面35。沿长度方向，第二绝缘壳体30的第三斜面34和第四斜面35位于第三压紧件121的第一斜面和第四压紧件122的第二斜面之间。
一方面，在将第二绝缘壳体30安装于加热芯体10上时，可以起到安装引导的作用，方便安装。另一方面，将第二绝缘壳体30安装于加热芯体10上后，加热芯体10可以在长度方向对第二绝缘壳体30起到限位作用。再一方面，由于第二绝缘壳体30与第三压紧件121和第四压紧件122是斜面配合，增大了相抵的接触面积，更好地提升第二绝缘壳体30与加热芯体10之间的密封性。
继续参考图1和图4，所述第一绝缘壳体20内设有第一分隔件22，所述第一分隔件22沿所述长度方向延伸，并将所述第一绝缘加热腔21分隔成相对独立的绝缘加热腔。图1和图4中示出了第一分隔件22的数量为一个，相应地，一个第一分隔件22将所述第一绝缘加热腔21分隔成两个相对独立的绝缘加热腔。但本申请对第一分隔件22的数量不做限制，在一些可能的实施方式中，例如是两个、三个等。
所述第一绝缘壳体20具有沿宽度方向相对设置的第一内壁和第二内壁，所述第一内壁、所述第二内壁以及所述第一分隔件22的长度方向的两端分别设有所述第三斜面和所述第四斜面。即，在第一绝缘壳体20的内部的长度方向的两端设置了与第一压紧件111和第二压紧件112斜面配合的第三斜面和第四斜面，节约了空间，还起到上述三方面的作用。
继续参考图1和图4，所述第二绝缘壳体30内设有第二分隔件32，所述第二分隔件32沿所述长度方向延伸，并将所述第二绝缘加热腔31分隔成相对独立的绝缘加热腔。图1和图4中示出了第二分隔件32的数量为一个，相应地，一个第二分隔件32将所述第二绝缘加热腔31分隔成两个相对独立的绝缘加热腔。但本申请对第二分隔件32的数量不做限制，在一些可能的实施方式中，例如是两个、三个等。
所述第二绝缘壳体30具有沿宽度方向相对设置的第一内壁和第二内壁，所述第一内壁、所述第二内壁以及所述第二分隔件32的长度方向的两端分别设有所述第三斜面34和所述第四斜面35。即，在第二绝缘壳体30的内部的长度方向的两端设置了与第三压紧件121和第四压紧件122斜面配合的第三斜面34和第四斜面35，节约了空间，还起到上述三方面的作用。
此外，本申请对加热芯体10的具体结构不做限制，能够实现对待加热流体的加热即可。通常加热芯体10由PTC陶瓷加热片和电极片组成，电极片通过粘结、焊接或者通过绝缘膜包裹的方式固定在PTC陶瓷加热片上。参考图1、图3和图4，本实施例中，所述加热芯体10包括PTC陶瓷发热片13、位于所述PTC陶瓷发热片13相反两侧的电极片14、导线15以及包覆所述PTC陶瓷发热片和所述电极片的绝缘层16。当所述加热器1工作时，电极片通过导线15通电时，PTC陶瓷发热片产生热量，加热流入第一绝缘加热腔21和第二绝缘加热腔31中的流体。
另外，绝缘层16的类型不做限制。例如是下述材料中的任意一种或多种：聚酰亚胺膜；绝缘陶瓷片；云母片；其它非金属或半导体绝缘导热材料。
继续参考图1至图4，沿所述加热器1的长度方向，所述第一绝缘壳体20的两端开口，包括第一开口23和第二开口24。所述第二绝缘壳体30的两端开口，包括第三开口33和第四开口36。第一绝缘壳体20的第一开口23和第二绝缘壳体30的第三开口33位于加热器1的长度方向的同一侧，第一绝缘壳体20的第二开口24和第二绝缘壳体30的第四开口36位于加热器1的长度方向的同一侧。
本实施例中，所述第一绝缘壳体20和所述第二绝缘壳体30的位于所述加热器1的长度方向的同一侧的第二开口24和第四开口36通过管道40连通，以实现所述第一绝缘加热腔21和所述第二绝缘加热腔31相连通。第二开口24和第四开口36与管道40在连接处分别设有密封圈41，防止漏水。图3中示出了待加热流体在加热器1的第一绝缘加热腔21和所述第二绝缘加热腔31中的流通方向。图3中示出待加热流体由第一绝缘壳体20的第一开口23流入第一绝缘加热腔21，并通过管道40流入第二绝缘加热腔31，再由第二绝缘壳体30的第三开口33流出，实现待加热流体在加热器1中的流通，完成被加热。
本申请还提供一种加热水池，包括上述任一项所述的加热器1。
