具体实施方式
为了便于理解本发明，下面将参照相关附图对本发明进行更全面的描述。附图中给出了本发明的较佳实施方式。但是，本发明可以以许多不同的形式来实现，并不限于本文所描述的实施方式。相反地，提供这些实施方式的目的是使对本发明的公开内容理解的更加透彻全面。
需要说明的是，当元件被称为“固定于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。本文所使用的术语“内”、“外”、“左”、“右”以及类似的表述只是为了说明的目的，并不表示是唯一的实施方式。
参阅图1和图2，本发明一实施例提供的加热雾化装置10包括加热器20和主机30，加热器20设置在主机30上，即主机30可以作为加热器20的安 装载体。主机30包括电池31，电池31与加热器20电性连接。通常地，主机30开设有容置腔32，加热器20设置在该容置腔32内。当雾化介质收容在该容置腔32时，加热器20插置在雾化介质中。当电池31对加热器20供电时，加热将电能转化为热能，雾化介质吸收该热能并雾化形成可供用户抽吸的气溶胶。事实上，加热器20的温度控制在合理的范围之内，确保对雾化介质起到低温烘烤作用，防止加热器20的温度过高而导致雾化介质产生燃烧，从而避免雾化介质因燃烧而产生大量有害物质，保证雾化介质在低温烘烤的作用下降低或消除有害物质的排放，从而提高加热器20和整个加热雾化装置10的使用安全性。
在一些实施例中，加热器20包括加热体100、电极体200和电连接件300。两个电极体200间隔设置，即电极体200沿垂直加热器20的长度方向间隔设置。加热体100被夹设在两个电极体200之间。电极体200的电阻率小于加热体100的电阻率，使得电极体200具有比加热体100更优异的导电性能。当电压加载在两个电极体200之间时，电流可以从其中一个电极体200(作为正极)沿垂直于加热器20的长度方向流入至另外一个电极体200(作为负极)，图2中虚线箭头所指方向即为电流方向。在电流流经夹设在两个电极体200之间的加热体100的过程中，加热体100因具有电阻而产生热量，以便雾化介质吸收该热量以雾化形成气溶胶。
在一些实施例中，电极体200可以采银、铜、合金或导电陶瓷等材料制成，如此使得电极体200具有相对较低的电阻率，确保电极体200具有良好的导电性能。电极体200可以与加热体100一体连接，例如电极体200可以通过印刷、涂覆、烧结或气相沉积等加工工艺与加热体100一体连接，如此可以省去电极体200和加热体100之间的粘接层，降低加热器20的制造成本，提高电极体200加热体100之间的连接强度以提高加热器20的使用寿命。
在一些实施例中，例如，电连接件300可以为具有一定柔韧性的引线310，引线310的数量为两根，两根引线310与两个电极体200形成一一对应关系。该引线310的一端与电极体200靠近电池31的一端电性连接，引线310的另 一端则与电池31电性连线，引线310可以通过钎焊工艺固定在电极体200上。工作时，电池31通过引线310对电极体200供电，从而使得加热体100内具有电流以产生热量。又如，电连接件300还可以为具有一定刚性的且呈柱状的连接柱，也可以为具有一定刚性且呈片状的连接片。
在一些实施例中，加热体100包括第一加热段110、第二加热段120和绝缘段130，第一加热段110和第二加热段120沿整个加热器20的长度方向间隔设置，第一加热段110相对第二加热段120更加靠近电池31设置，可以简单理解为第一加热段110为加热体100的下段，第二加热段120为加热体100的上段。绝缘段130连接在第一加热段110和第二加热段120之间，绝缘段130一方面起到绝缘作用，防止第一加热段110和第二加热段120两者形成串联电路；另一方面起到固定作用，确保第二加热段120通过该绝缘段130固定在第一加热段110上，从而实现第一加热段110和第二加热段120两者之间的物理连接；故绝缘段130具有连接固定和绝缘功能。绝缘段130可以选用玻璃、黏土或陶瓷等无机粘接剂制成，如此确保第一加热段110和第二加热段120两者均能与绝缘段130之间形成较高的结合强度，从而提高整个加热体100的机械强度。在其他实施例中，绝缘段130可以省略，此时，绝缘段130可以理解为空气层，该空气层同样能够对第一加热段110和第二加热段120起到绝缘作用。在一些实施例中，第一加热段110可以采用金属、合金或导电陶瓷材料制成，使得第一加热段110的电阻的取值范围为3Ω至5Ω，例如第一加热段110电阻的具体取值可以为3Ω、4Ω、4.5Ω或5Ω等。第一加热段110具有正的电阻温度系数特性，使得第一加热段110的电阻随着温度的升高而增大，可以理解为第一加热段110的电阻与温度成正比。第二加热段120可以采用包含LSM或LSCF物质的半导体陶瓷材料制成，使得第一加热段110的电阻的取值范围为2Ω至4Ω，例如第一加热段110电阻的具体取值可以为2Ω、3Ω、3.5Ω或4Ω等。第二加热段120具有负的电阻温度系数特性，使得第二加热段120的电阻随着温度的升高而减少，可以理解为第二加热段120的电阻与温度成反比。
在一些实施例中，参阅图4，加热体100可以为圆柱或棱柱等柱状结构，参阅图3，加热体100也可以为片状结构，故整个加热器20也可以为柱状或片状结构。第一加热段110和第二加热段120两者形成并联电路，故加载在第一加热段110和第二加热段120上的电压均相等，加热段的电阻变小时，该加热段的发热功率将增大。第二加热段120的长度可以大于第一加热段110的长度，第二加热段120的长度也可以等于第一加热段110的长度。
参阅图5，因此，在第一加热段110的升温过程中，第一加热段110的电阻增大，使得第一加热段110的功率变小；当第一加热段110升温至雾化温度而保持恒定时，该雾化温度记为第一雾化温度T 1，第一加热段110通过该第一雾化温度T 1对雾化介质进行加热雾化，鉴于第一雾化温度T 1不变，第一加热段110的功率保持恒定。在第二加热段120的升温过程中，第二加热段120的电阻减少，使得第二加热段120的功率变大；当第二加热段120升温至雾化温度而保持恒定时，该雾化温度记为第二雾化温度T 2，第二加热段120通过该第二雾化温度T 2对雾化介质进行加热雾化，鉴于第二雾化温度T 2不变，第二加热段120的功率保持恒定。
参阅图5，在同一平面直角坐标系中，第一加热段110的温度随时间的变化图线可以为直线111，第二加热段120的温度随时间的变化图线可以为曲线121。显然，在电池31并未给加热体100供电的初始时刻(也即零时刻)，第一加热段110和第二加热段120两者的初始温度相等，即初始温度均可以等于环境温度。当电池31给加热体100通电时，第一加热段110沿着直线111升温至第一雾化温度T 1；第二加热段120沿曲线121升温至第二雾化温度T 2。上述直线111和曲线121存在一个交点140，将该交点140所对应的时刻记为等温时刻t。显然，在该等温时刻t，第一加热段110和第二加热段120的温度相等，且两者的温度均大于初始温度。在等温时刻t之前，第一加热段110的温度大于第二加热段120的温度，在等温时刻t之后，第一加热段110的温度小于第二加热段120的温度。
鉴于第二雾化温度T 2大于第一雾化温度T 1，沿整个加热器20的长度方向， 加热器20的温度场将具有一定的梯度，从而呈现出特定的分布规律。同时，在升温过程中，第一加热段110功率变小，而第二加热段120的功率变大，如此可以改变雾化介质雾化形成的气溶胶的成分和浓度，从而提升气溶胶的抽吸口感。
参阅图1和图2，为描述方便起见，将加热器20与第一加热段110对应的部分记为第一加热部101，第一加热部101包括第一加热段110和电极体200覆盖第一加热段110的部分。加热器20与第二加热段120对应的部分记为第二加热部102，第二加热部102包括第二加热段120和电极体200覆盖第二加热段120的部分。第一加热部101直接固定在主机30上，第二加热部102为自由端。鉴于第一加热段110的第一雾化温度T 1相对较小，故第一加热部101的温度较小，如此可以减少加热器20对主机30的热量传递，提高加热器20的能量利用率，也避免热量对主机30内部零部件所构成的不利影响。同时，第二加热部102完全插置在雾化介质中，即雾化介质完全包裹第二加热部102，鉴于第二加热段120的第二雾化温度T 2较高，可以使得雾化介质在较短时间内快速通过低温烘烤的方式雾化形成气溶胶，从而提高加热器20对用户抽吸响应的灵敏度。
加热体100本身具有足够的结构强度，无需将加热体100附着在其他加强部件上，即加热体100具有良好的“自支撑”能力，如此可以省去加强部件的设置，一方面简化加热器20的结构，另一方面加热体100产生的热量无需通过加强部件传递至雾化介质上，即加热体100的热量直接传递至雾化介质，如此可以提高加热器20的热传递效率和能量利用率。
加热器20还可以包括釉层，釉层附着在电极体200和加热体100的表面。通过设置釉层，既可以防止雾化介质在加热雾化过程中产生的粘稠状物质对加热体100和电极体200构成侵蚀，还可以充分利用釉层具有较为光滑的表面，从而有效防止粘稠状物质粘附在釉层上，提高加热器20的清洁度。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这 些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
