 本发明的实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。需要理解的是，如果文中出现“前”、“后”、“上”、“下”、“左”、“右”、“纵”、“横”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“头”、“尾”等指示的方位或位置关系为基于附图所示的方位或位置关系、以特定的方位构造和操作，仅是为了便于描述本技术方案，而不是指示所指的装置或元件必须具有特定的方位，因此不能理解为对本发明的限制。还需要说明的是，除非另有明确的规定和限定，如果文中出现“安装”、“相连”、“连接”、“固定”、“设置”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。当一个元件被称为在另一元件“上”或“下”时，该元件能够“直接地”或“间接地”位于另一元件之上，或者也可能存在一个或更多个居间元件。如果文中出现术语“第一”、“第二”、“第三”等仅是为了便于描述本技术方案，而不能理解为指示或暗示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”、“第三”等的特征可以明示或者隐含地包括一个或者更多个该特征。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
以下描述中，为了说明而不是为了限定，提出了诸如特定系统结构、技术之类的具体细节，以便透彻理解本发明实施例。然而，本领域的技术人员应当清楚，在没有这些具体细节的其它实施例中也可以实现本发明。在其它情况中，省略对众所周知的系统、装置、电路以及方法的详细说明，以免不必要的细节妨碍本发明的描述。
参见图2，经研究，关于背景技术所说的问题——要么烟味口感出不来，要么容易形成积碳影响使用寿命的，原因是加热体41周向都产生热量，且周向的热量差异不大，但是进气气流经过的为加热体41的下半圆部分，上半圆部分发热区域热量会高于下半圆区域造成温度分布不均（即上半圆区域温度高下半圆区域温度低）。对此，本发明提供一种改进的不同部位加热效果不同的雾化装置加热体。至于产生焦味的问题，原因是，现有的加热组件通常从导液体41的两端吸取液体，液体从导液体41两端进入到达中间位置，液体流动路径较长，加热组件持续加热时容易导致供液不足产生焦味。
参见图3-5，本发明的一种实施方式中的不同部位加热效果不同的雾化装置加热体1，用于将液体加热雾化，整体呈管状并且径向尺寸为1-17mm、轴向尺寸为2-33mm以及壁厚为0.02-0.9mm，加热体1可以为圆管或方管状，对于方管状而言，上述径向尺寸相当于宽度和高度，轴向尺寸相当于长度。该尺寸的加热体通常具有较合适的电阻，具有较好的加热效果。加热体1包括分别设在轴向两端的两个电极部12以及电性连接在两个电极部12之间的加热电路部分11，加热电路部分11包括周向依次设置的一组第一连接部111、一组第二连接部112、一组第三连接部113和一组第四连接部114，该组第一连接部111包括轴向间隔分布的多个第一连接部111，该组第二连接部112包括轴向间隔分布的多个第二连接部112，该组第三连接部113包括轴向间隔分布的多个第三连接部113，该组第四连接部114包括轴向间隔分布的多个第四连接部114；
第一连接部111和第三连接部113的轴向尺寸大于第二连接部112和第四连接部114的轴向尺寸，每个第一连接部111连接相邻两个第二连接部112和相邻两个第四连接部114，每个第三连接部113连接相邻两个第二连接部112和相邻两个第四连接部114，以使第一连接部111、第二连接部112和第三连接部113连接成第一电路11a，第三连接部113、第四连接部114和第一连接部111连接成第二电路11b，第一电路11a与第二电路11b并联，电极部12通电时，第一电路11a和第二电路11b发热，加热体1的径向一侧A在单位时间发热量小于径向另一侧B在单位时间发热量。
加热电路部分11的结构可以通过镂空的方式形成，加热体1优选是一体的。
该加热体1应用于雾化装置时，导液体2可以穿设在加热体1中，导液体2将液体传导到加热体1进行加热雾化，气流经过加热体1将雾化气体带出。当雾化装置为电子烟时，该加热体1在电子烟中对烟液进行加热雾化。
加热体1的发热面集中在一侧B，另一侧A发热量少或者不发热。该加热体1应用于电子烟之类的雾化装置中时，可以使气流经过B侧，这样就不会存在温差大的问题，改善烟味口感，也不会因温度过高而形成积碳。此外，液体可以从A侧的间隙进入导液体2，这样可以避免两端进液，液体流动路径过长导致的供液不足产生的焦味问题。
在一些实施例中，参见图3-5，电极部12呈环绕加热体1轴线的环状；在另一些实施例中，电极部12呈轴向或径向突出的形状。
在一些实施方式中，参见图3-5，第一连接部111设在轴向一侧A，第二连接部112、第三连接部113和第四连接部114设在另一侧B，第一连接部111的截面积大于第三连接部113的周向截面积，第一连接部111的周向尺寸大于第二连接部112、第三连接部113和第四连接部114的周向尺寸，由于截面积大，电阻小，所以在单位时间发热量就较小，所以第一连接部111在单位时间发热量小于第二连接部112、第三连接部113和第四连接部114在单位时间发热量，以使加热体1的径向一侧A在单位时间发热量小于径向另一侧B在单位时间发热量。
参见图3-5，优选地，从所述加热体1的中部到两端，所述第一连接部111的周向尺寸相等，所述第二连接部112的周向尺寸相等，所述第四连接部114的周向尺寸相等，第二连接部112的周向尺寸等于第四连接部114的周向尺寸。
参见图3-5，优选地，第一连接部111上设有贯通内外的进液孔1111，当加热体1应用于雾化装置中时，液体可以从第一电路11a那一侧进入导液体2，进液孔1111可以提高进液效率，以实现更加充足的供液。
参见图13-14，加热体1的连接部的尺寸也可以是，从所述加热体1的中部到两端，所述第一连接部111的周向尺寸增大，所述第二连接部112的周向尺寸减小，所述第四连接部114的周向尺寸减小。第一连接部111、第二连接部112和第四连接部114的周向尺寸变化方式可以是渐变式的（参见图13-14），也可以是阶段式的（参见图15）。当加热体1应用于雾化装置中时，液体可以从第一电路11a那一侧进入导液体2，由于热量辐射原理，中间段温度高，气流进气口也在加热体1的中间部位，本实施例的加热体将发热区集中在加热体的中间部位。这样中间段具有较大的发热雾化区域，气流量也较大，可以达到热量均衡的效果。
参见图16-17，加热体1的连接部的尺寸也可以是，从所述加热体1的中部到两端，所述第一连接部111的周向尺寸减小，所述第二连接部112的周向尺寸增大，所述第四连接部114的周向尺寸增大。第一连接部111、第二连接部112和第四连接部114的周向尺寸变化方式可以是渐变式的（参见图16-17），也可以是阶段式的（参见图18）。当加热体1应用于雾化装置中时，可以采用从加热体的轴向两端向中间进液的进液方式，由于本实施例的加热体中间段发热线路较短，两端线路长（雾化面积对应的中间小，两端较大），可以更好的和供液距离匹配，达到均衡的效果。避免了因加热体1中间段热量高而液体供给较远，造成中间段的液体供应不上而产生糊芯的可能。
在一些实施方式中，参见图6-8，第二连接部112的周向尺寸大于第四连接部114的周向尺寸，第二连接部112在单位时间发热量小于第四连接部114在单位时间发热量，以使加热体1的径向一侧A在单位时间发热量小于径向另一侧B在单位时间发热量。
参见图6-8，优选地，第二连接部112和第四连接部114的轴向尺寸相等；这样，第一电路11a发热线路远长与第二电路11b，这样第一电路11a的电阻远大与第二电路11b，而第一电路11a和第二电路11b为并联电路,电路两端电压相同，因此根据I=U/R，第一电路11a的电流要远小于第二电路11b，因而根据功率P=I²R=UI，第一电路11a的功率远小于第二电路11b的功率，因此第一电路11a的热量远低于第二电路11b。
在一些实施方式中，参见图9-12，第二连接部112和第四连接部114分别设在加热体1的径向两侧，第二连接部112的轴向尺寸小于第四连接部114的轴向尺寸，第二连接部112之间的间距大于第四连接部114之间的间距，第二连接部112在单位时间的发热量小于第四连接部114在单位时间的发热量，以使加热体1的径向一侧A在单位时间发热量小于径向另一侧B在单位时间发热量。
参见图9-12，优选地，第二连接部112和第四连接部114的周向尺寸相等。
在上述图6-12的实施方式中，优选地，第一连接部111和第三连接部113的周向尺寸小于第二连接部112和第四连接部114的周向尺寸。
在上述技术方案中，优选地，各个第二连接部112的周向尺寸相等，各个第四连接部114的周向尺寸相等，各个第一连接部111的周向尺寸相等，各个第三连接部113的周向尺寸相等。加热体1的各个部分厚度相等，也即径向尺寸相等。
在上述技术方案中，优选地，第一连接部111和第三连接部113在轴向上错开。
在上述技术方案中，优选地，加热电路部分11通过第一连接部111或第三连接部113连接两个电极部12。
参见图19-21，本发明的一种实施方式的雾化装置，包括上述的加热体1，还包括壳体3和导液体2，导液体2穿设在加热体1中，壳体3中设有液道31和进气道32和出气道33，储液仓34可以设在壳体3中或者壳体3外部，与液道31连通，液道31和进气道32分别通向加热体1的径向两侧，加热体通电时，液道31所通向的加热体1的一侧在单位时间的发热量小于进气道32所通向的加热体1的一侧在单位时间的发热量，在图19-21的实施例中，液道31通向加热体1上侧，进气道32通向加热体1下侧，液体透过加热体1的上侧进入导液体2，导液体2将液体传导到加热体1进行加热雾化，外部气流经进气道32进入壳体3，经过加热体1，将雾化气体从出气道33带出壳体3外。
该雾化装置的液体直接从管状加热体的径向一侧沿着径向方向供油，路径更短，供液充分。下侧发热效率较高，和气流的路径更加匹配，避免了上方气流不易经过的面热量高的问题。加热体1下册的热量会传导到上侧，传导上去的热量可以预热烟液，使得烟液的运动粘度变小，使得液体供应的更加充足，进一步的防止了供液不足引起的干烧和温度过高产生的一些有害物质的一些问题。
参见图22-24，本发明的另一种实施方式的雾化装置，一种雾化装置，包括上述加热体1，还包括壳体3和导液体2，导液体2穿设在加热体1中并且轴向两端伸出加热体1外，壳体3中设有液道31和进气道32和出气道33，储液仓34可以设在壳体3中或者壳体3外部，与液道31连通，液道31通向导液体2的伸出加热体1外的两端，进气道32通向加热体1的径向一侧，进气道32所通向的加热体1的一侧在单位时间的发热量大于另一侧在单位时间的发热量，在图22-24的实施例中，进气道32通向加热体1下侧，两一侧为上侧；液体与导液体2两端接触，导液体2将液体传导到加热体1进行加热雾化，外部气流经进气道32进入壳体3，经过加热体1，将雾化气体从出气道33带出壳体3外。
对比传统的导液棉在中间外围缠绕加热体，传统的加热体周向都有热量产生，而气流未经过加热体的正上方，未将温度较高的雾化蒸汽带出雾化仓，这样就会导致雾化效果差，一些烟液的风味出不来。还有就是上方的无效发热区域浪费电能，造成电池续航差的问题。该雾化装置，通过对管状加热体1的热量分布设计，可以达到加热雾化面和气流经过的导液体2匹配，到达热量均衡的效果，使得在使用过程中抽吸有气流流动的情况下加热雾化组件产生的热量更加均衡，雾化效果好，而且还可以节省电能，使得电池续航更长，避免了多余的能量浪费。
本发明的雾化装置可以应用于电子烟上，储液仓34中存储烟液，通过加热体1加热雾化烟液。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改、组合和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的权利要求范围之内。
