附图说明
下面将结合附图及实施例对本发明作进一步说明，附图中：
图 1 是现有的电子烟的吸嘴盖受到外力挤压时所处的状态；
图 2 是本发明的电子烟的吸嘴盖受到外力挤压时所处的状态；
图 3 是本发明第一实施例提供的吸嘴盖的结构剖视图；

具体实施方式
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。
如图 1 所示，是现有的电子烟的吸嘴盖受到外力挤压时所处的状态，由于现有的吸嘴盖的端部为平面，当吸嘴盖的两外侧受到径向外力挤压时，该径向外力为垂直于所述外套管方向的力，吸嘴盖就会产生沿轴向向外（脱离外套管的方向）运动的趋势，会导致吸嘴盖从电子烟上脱落，从而导致该电子烟不能供用户吸食，影响用户体验。
如图 2 和 3 所示，本发明第一实施例提供的电子烟，包括外套管 10 和吸嘴盖 20 。其中外套管 10 大致为中空的筒状结构，吸嘴盖 20 套设在外套管 10 内，且外套管 10 和吸嘴盖 20 为可拆卸地连接或一体成型结构。外套管 10 可以是雾化器的管套、电池上的管套或套在雾化器与电池上的管套，还可以是雾化器的一部分。
吸嘴盖 20 大致为筒状，采用硅胶材料制成，其具有良好的弹性、耐腐蚀等特性，可以理解的是，吸嘴盖 20 亦可采用橡胶等柔性材料制成。吸嘴盖 20 上与口腔相对的表面为凹面 230 ，当吸嘴盖 20 的两外侧受到径向外力挤压时，该径向外力为垂直于所述外套管方向的力，吸嘴盖 20 就会产生沿轴向向内（朝向本体内部）运动的趋势，从而防止吸嘴盖 20 从电子烟上脱落。
吸嘴盖 20 包括内中空的本体 220 、第一端部 210 和第二端部 240 。其中，本体 220 为中空的筒状并套设在外套管 10 内，第一端部 210 盖设在外套管 10 上，第二端部 240 向本体 220 内凹陷形成凹面 230 。第二端部 240 上设有至少一个吸烟口 242 ，电子烟内雾化的烟雾经吸烟口 242 吸入用户口内。吸烟口 242 包括位于第二端部 240 上的贯穿孔 2422 和沿贯穿孔 2422 的边缘向本体 220 内轴向延伸的通孔 2424 ，且通孔 2424 与贯穿孔 2422 的内径相等。吸烟口 242 可以设置在本体 220 的中心轴线上，也可以设置在偏离中心轴线的位置上。设置多个吸烟口 242 时，多个吸烟口 242 可以是均匀间隔对称设置。具体在本实施方式中，吸烟口 242 的形状可以采用三角形、多边形（五边形、六边形等）、椭圆形中的任意一种。且吸烟口 242 的个数也不限于此，可以为 1 个或更多个。当吸烟口 242 的个数较少时，相应的烟雾流量会较小，当吸烟口 242 的个数较多时，烟雾流量相对较大。
为了防止吸嘴盖 20 从外套管 10 中弹出被正在吸食香烟的用户误吞，将吸嘴盖 20 与外套管 10 之间设为卡扣连接。具体地本体 220 的外侧壁上设有呈凸起状的卡扣 222 ，相应地，外套管 10 上与卡扣 222 相对应的内壁上设有与该卡扣 222 相扣合连接的卡槽（图未示），通过卡扣 222 与卡槽的扣合连接，从而将吸嘴盖 20 和外套管 10 可拆卸地连接。可以理解的是，在其它实施方式中，本体 220 的外侧壁上可以设有卡槽（图未示），外套管 10 的内壁设有用于与该卡槽相扣合的卡扣（图未示），通过卡槽与卡扣的扣合，从而将外套管 10 与吸嘴盖 20 可拆卸地连接起来。
由于凹面 230 具有一定的缓冲作用，当吸嘴盖 20 的两侧受到径向外力挤压时，该径向外力为垂直于所述外套管 10 方向的力，第二端部 240 沿轴向向内（朝向本体 220 内部的方向为向内）的受力大于向外（朝向本体 220 外部的方向为向外）的受力，从而改变吸嘴盖 20 的运动趋势，即吸嘴盖 20 受到外力挤压时，吸嘴盖 20 会产生向外套管 10 内部运动的趋势，从而防止吸嘴盖 20 从电子烟上脱落，提高用户提高。
如图 2 所示，是本发明的电子烟的吸嘴盖 20 受到外力挤压时所处的状态，由于吸嘴盖 20 具有缓冲作用的凹面 230 ，当吸嘴盖 20 的两外侧受到径向外力挤压时，吸嘴盖 20 会产生向本体 220 内运动的趋势，避免吸嘴盖 20 从电子烟上脱落，提高用户体验。
如图 3 所示，本发明第一实施例提供的电子烟中，凹面 230 包括相互平行设置的第一直线段 232 和第二直线段 234 、以及与第一直线段 232 连接的第一弧线段 236 ，与第二直线段 234 连接的第二弧线段 238 ，则第一直线段 232 、第二直线段 234 、第一弧线段 236 和第二弧线段 238 共同围成该凹面 230 。第一直线段 232 和第二直线段 234 分别位于本体 220 的两相对边上，第一弧线段 236 和第二弧线段 238 的另一端分别与吸烟口 242 连接，且第一弧线段 236 和第二弧线段 238 均位于第二端部 240 上。
第二端部 240 与本体 220 的中心轴的交点到第一端部 210 的垂直距离为 0.3 厘米～ 1 厘米，即凹面 230 的最大深度在 0.3 厘米～ 1 厘米之间。若凹面 230 的最大深度小于 0.3 厘米，则在电子烟受到外力挤压时，不能有效地改变吸嘴盖 20 的运动趋势，存有使吸嘴盖 20 从电子烟内脱落的隐患，若凹面 230 的最大深度大于 1 厘米，则会给用户吸食电子烟带来不便；优选地，凹面 230 的最大深度为 0.6 厘米。第一端部 210 、本体 220 、第二端部 240 和通孔 2424 为一体成型结构，便于加工制作，且整体效果好。
如图 4 所示，本发明第二实施例提供的电子烟，其与第一实施例的区别在于：该凹面 230 的截面为弧形槽，且第一端部 210 包括上端部 212 和下端部 214 ，该弧形槽沿上端部 212 向下凹陷形成，弧形槽的弦长等于本体 220 的内径 。
如图 5 所示，本发明第三实施例提供的电子烟，其与第一实施例的区别在于：该凹面 230 的截面为矩形槽， 矩形槽的宽度等于本体 220 的内径 。
如图 6 所示，本发明第四实施例提供的电子烟，其与第一实施例的区别在于：该凹面的截面为等腰梯形槽，该等腰梯形槽的侧边与外套管 10 的中心轴线的夹角为 10 ° ～ 40 °，优选地，等腰梯形槽的侧边与外套管 10 的中心轴线的夹角为 120 ℃。
本发明提供的电子烟，由于第二端部 240 向本体 220 内凹陷形成凹面 230 ，当吸嘴盖 20 的两外侧受到径向外力挤压时，第二端部 240 向内的受力大于向外的受力，则吸嘴盖 20 产生向本体 220 内运动的趋势，从而避免了吸嘴盖 20 从电子烟内脱落，此外，具有这种结构的电子烟，用户叼烟时感觉更有弹性，提高用户体验；另外，当有少量烟油从吸烟口 242 出来时，可避免用户吸到烟油。
上面结合附图对本发明的实施例进行了描述，但是本发明并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本发明的启示下，在不脱离本发明宗旨和权利要求所保护的范围情况下，还可做出很多形式，例如，凹面 230 的截面呈 V 形或 W 形等， 这些均属于本发明的保护之内。
