具体实施方式
以下结合附图对本实用新型作进一步详细说明。
本具体实施例仅仅是对本实用新型的解释，其并不是对本实用新型的限制，本领域技术人员在阅读完本说明书后可以根据需要对本实施例做出没有创造贡献的修改，但只要在本实用新型的权利要求范围内都受到专利法的保护。
本实施例涉及一种电磁加热结构100，请参照图1-图6，包括：磁芯110、金属件、以及绕设在磁芯110上的线圈120。
磁芯110包括：缠绕部111和两个延伸部112。其中，缠绕部111用于供磁芯110缠绕。两个延伸部112分别从缠绕部111的两端向同一方向延伸，两个延伸部112之间具有加热空间a，且两个延伸部112之间任一位置处均保持有距离，即两个延伸部112之间不接触。金属件设置于加热空间a内的中心处。
当线圈120通电后，在磁芯110的作用下，把原来不规则的交变感应磁场，导通至磁芯110的两个延伸部112，在两个延伸部112产生均匀的交变感应磁场，导向金属件的周围，即交变感应磁场围绕住金属件，不会往外传播，能快速加热金属件。
采用该电磁加热结构100，线圈120的线径可以为1mm，甚至还可以小于1mm，而传统的电磁加热结构的线圈的线径在2mm左右。
作为一个优选的方案，磁芯110为铁氧体磁芯110，减小线圈120产生的感应磁场的磁损，提高加热效率。
采用上述的磁芯110和铁氧体磁芯110，工作效率高，可靠性高，磁泄漏 少，可使线圈120小型化。
为了更清楚的描述该电磁加热结构100，以下列举几个具体实施例。
实施例一：本实施例提及一种电磁加热结构100，请参照图1-图2，两个延伸部112分别从缠绕部111的两端向缠绕部111的上侧延伸，加热空间a也位于缠绕部111的上侧。两个延伸部112对称设置，且呈弧形状。两个延伸部112之间形成圆柱状的空间，该空间即为加热空间a。当然在其他实施例中，延伸部112可以为其他形状，对应的，两个延伸部112之间也可以形成其他形状，以适应不同外形的金属杯130或固定气溶胶基质300。
更具体地，如图2所示，金属件为金属杯130，即该电磁加热结构100为周向加热型。金属杯130用于供热可逆的固定气溶胶基质300放置。当线圈120通电后，线圈120产生交变感应磁场，磁芯110将线圈120产生的交变感应磁场均匀导向金属杯130的周围，均匀加热金属杯130，金属杯130进而加热位于其内部的热可逆的固定气溶胶基质300。热可逆的固定气溶胶基质300可拆卸式放置于金属杯130内，即热可逆的固定气溶胶基质300可更换。采用金属杯130作为金属件，加热面积大，传热效率高。
除此之外，如图2所示，电磁加热结构100还包括：盖设于延伸部112上侧的盖子150。盖子150留有供热可逆的固定气溶胶基质300进入加热空间a内的开口。
实施例二：本实施例提及一种电磁加热结构100，请参照图3，其磁芯110和线圈120的布置方式与实施例一相同，不同之处在于，金属件为设置于加热空间a内中部位置的金属条140，即该电磁加热结构100为内加热型。金属条140用于供热可逆的固定气溶胶基质300插接。当线圈120通电后，线圈120产生交变感应磁场，磁芯110将线圈120产生的交变感应磁场均匀导向金 属条140的周围，均匀加热金属条140，金属杯130进而加热位于其外部的热可逆的固定气溶胶基质300。热可逆的固定气溶胶基质300可拆卸式插接于金属条140上，即热可逆的固定气溶胶基质300可更换。采用金属条140作为金属件，热量利用率高、隔热效果好。
除了和实施例一同样设置有盖子150外，如图所示，电磁加热结构100还包括：设置于加热空间a内的托架160。托架160用于承托金属条140和热可逆的固定气溶胶基质300。具体在本实施例中，盖子150和托架160为一体结构。
实施例三：本实施例提及一种电磁加热结构100，请参照图4-图5，延伸部112的延伸方向为：朝向缠绕部111的左侧，加热空间a也位于缠绕部111的左侧。当然在其他实施例中，延伸部112的延伸方向可以为：朝向缠绕部111的右侧，相应的，加热空间a也位于缠绕部111的右侧。这种设计使得加热空间a和线圈120并排设置，空间利用率更大。两个延伸部112对称设置，且延伸部112上具有弧形结构。两个延伸部112的弧形结构之间形成圆柱状的空间，该空间即为加热空间a。
金属件为设置于所述加热空间a内中部位置的金属条140，用于供热可逆的固定气溶胶基质300插接。更具体地，如图所示，金属件为金属杯130，即该电磁加热结构100为周向加热型。金属杯130用于供热可逆的固定气溶胶基质300放置。当线圈120通电后，线圈120产生交变感应磁场，磁芯110将线圈120产生的交变感应磁场均匀导向金属杯130的周围，均匀加热金属杯130，金属杯130进而加热位于其内部的热可逆的固定气溶胶基质300。热可逆的固定气溶胶基质300可拆卸式放置于金属杯130内，即热可逆的固定气溶胶基质300可更换。采用金属杯130作为金属件，加热面积大，传热效 率高。
除此之外，如图5所示，电磁加热结构100还包括：盖设于延伸部112上侧的盖子150。盖子150留有供热可逆的固定气溶胶基质300进入加热空间a内的开口。
实施例四：本实施例提及一种电磁加热结构100，请参照图6，与实施例三不同之处在于，两个延伸部112非对称设置，延伸部112上具有弧形结构，两个延伸部112上的弧形结构错位设置，同样在两个延伸部112的弧形结构之间形成圆柱状的空间，该空间即为加热空间a。
本申请还提供一种雾化装置200，包括：如实施例一至实施例四任意一项所述的电磁加热结构100。
为了更清楚的描述该电磁加热结构100，以下列举几个具体实施例。
实施例五：本实施例提及一种雾化装置200，请参照图7-图9，包括：外壳210，设置于外壳210内的支架240，设置于外壳210内、且安装在支架240内的电池230，设置于外壳210内、且安装在支架240上、与电池230电性连接的PCB板220，以及设置于外壳210的内部上侧的、如实施例一所述的电磁加热结构100。
实施例六：本实施例提及一种雾化装置200，请参照图10，包括：外壳210，设置于外壳210内的支架240，设置于外壳210内、且安装在支架240内的电池230，设置于外壳210内、同样安装在支架240内、且位于电池230上侧、与电池230电性连接的PCB板220，以及设置于外壳210的内部上侧的、如实施例三所述的电磁加热结构100。
本发明的工作原理大致如下述：适用于HNB加热不燃烧，当供电时，线圈120会产生交变感应磁场，通过磁芯110把原来的不规则的向外传播的交 变感应磁场变为在延伸部112产生均匀的交变感应磁场，同时环绕金属体的周围，金属体会产生涡流，使涡流与原子之间剧烈的对撞及摩擦，最终金属体产生热量，供热可逆的固定气溶胶基质300加热不燃烧的作用。
以上，仅用以说明本实用新型的技术方案而非限制，本领域普通技术人员对本实用新型的技术方案所做的其它修改或者等同替换，只要不脱离本实用新型技术方案的精神和范围，均应涵盖在本实用新型的权利要求范围当中。
