Description

一种电子烟雾化器 技术领域
本发明涉及一种电子烟雾化器。
背景技术
现有的电子烟雾化器一般采用发热丝加热储油棉中的烟油，加热过程中发热丝温度较高，容易烧焦，产生糊味，并且发热丝产生的高温容易传到雾化器外壁，使电子烟发烫，能量利用率低，吸烟口感差，同时雾化器容易漏油。
发明内容
本发明所要解决的技术问题是，针对现有技术不足，提供一种电子烟雾化器。
为解决上述技术问题，本发明所采用的技术方案是：一种电子烟雾化器，包括外套和与所述外套一端连接的吸嘴；所述外套内设有烟油腔和雾化芯；所述雾化芯包括第一超声雾化组件和第二超声雾化组件，所述第一超声雾化组件和第二超声雾化组件相对设置；所述第一超声雾化组件和第二超声雾化组件之间设有空隙，以使所述第一超声雾化组件和第二超声雾化组件雾化后的汽雾被对应所述第一超声雾化组件或第二超声雾化组件再次雾化，解决汽雾颗粒大而影响吸烟口感的问题；所述空隙与吸嘴连通；所述所述第一超声雾化组件和第二超声雾化组件分别与第一储油体、第二储油体接触；所述第一储油体和第二储油体均与所述烟油腔连通。

所述第一储油体的一端盖设在所述第一雾化面上，另一端与所述烟油腔连通；所述第二储油体一端盖设在所述第二雾化面上，另一端与所述烟油腔连通；以使所述第一储油体和第二储油体将所述烟油腔内的液体导至所述所述第一雾化面和第二雾化面上。
所述第一超声雾化组件和第二超声雾化组件均与所述外套沿所述超声波雾化器的纵向延伸设置，以使在竖直放置该超声波雾化器时所述第一超声雾化组件和第二超声雾化组件呈竖直状态，所述储液体远离所述吸嘴的一端与所述烟油腔连通。烟油从储液体底部渗透到整个储液体上，由于烟油是逆重力方向渗透的，因此不会在雾化面上沉积过多的烟油，可以有效解决雾化器启动慢和第一口烟雾量小的问题。
所述第一超声雾化组件和第二超声雾化组件均与沿所述外套纵向延伸设置，以使在竖直放置该超声波雾化器时所述压电陶瓷片呈竖直状态。
本发明的一种优选方案中，雾化芯与所述烟油腔并排设置。

所述第一压电陶瓷片与所述第一储油体接触的一面为所述第一雾化面。所述导油体固定在硅胶套内，所述硅胶套穿设固定在所述第二安装孔内，硅胶套保证导油体更加稳固。所述第二超声雾化组件包括第二压电陶瓷片和第二支架；所述第二支架上设有用于安装所述第二压电陶瓷片的容纳腔；所述第二压电陶瓷片相对所述第一压电陶瓷片的一面与所述第二储油体接触；所述第二储油体上带有凸起，该凸起与所述导油体伸出所述第二安装孔的一端接触。所述第二压电陶瓷片与所述第二储油体接触的一面为所述第二雾化面。以使得所述第一雾化面和第二雾化面相对设置，气流通过第一储油体的背向所述第一雾化面的表面和所述第二储油体的背向所述第二雾化面的表面之间的空隙将烟雾带走，有效的提高烟雾量和烟雾口感。
本发明的另一种实施例中，所述雾化芯设在所述烟油腔内的腔体内。
所述第一超声雾化组件包括第一压电陶瓷片和第一弹性垫；所述第一压电陶瓷片通过所述第一弹性垫与所述腔体内壁抵持连接；所述第二超声雾化组件包括第二压电陶瓷片；所述第二压电陶瓷片通过第二弹性垫与所述腔体内壁抵持连接。方便拆卸以及提高第一压电陶瓷片和第二压电陶瓷片的寿命。

如图5，实施例1的雾化器，其外套上开设了观察窗19，便于观察烟油腔1内的烟油储备情况。外套3靠近吸嘴的端部设有加油塞32，打开加油塞，即可往烟油腔1内添加烟油。外套3侧面开设了进气孔33，进气孔33与空隙4连通。
如图6和图7，本发明实施例2的雾化器包括外套3，外套3内设有烟油腔1，烟油腔1中部设有腔体5，该腔体5用于固定第一超声雾化组件和第二超声雾化组件。腔体5的顶端伸出外套3，并与吸嘴6连接，腔体5与吸嘴6内腔相通。
如图8，第一超声雾化组件包括第一压电陶瓷片8；所述第一压电陶瓷片8通过第一弹性垫23与所述腔体5内壁固定连接；第二超声雾化组件包括第二压电陶瓷片14；所述第二压电陶瓷片14通过第二弹性垫28与所述腔体5内壁固定连接。外套3靠近吸嘴的端部设有加油塞32，打开加油塞，即可往烟油腔1内添加烟油。
如图8，第一弹性垫23和第二弹性垫28上均设有弹性柱34，当两个压电陶瓷片分别与对应的弹性垫贴合时，弹性柱可以防止压电陶瓷片和弹性垫之间无空隙贴合而堵塞烟气通道，影响吸烟效果。
第一弹性垫23的中部设置有第一通孔17；所述第二弹性垫28的中部设置有第二通孔18；所述第一通孔17和第二通孔18位于所述第一压电陶瓷片8和第二压电陶瓷片14之间，并连通所述第一雾化面和第二雾化面。
如图7，外套3远离吸嘴6的一端通过底盖35密封，底盖35上固定有电极36，电极36通过绝缘环37与底盖35绝缘，电极36一端伸入腔体5内。
本发明的雾化面是指压电陶瓷片与储液体接触的一面(即可以喷出雾化气体的一面)。
两个陶瓷雾化片的雾化面相对设置，当其中一个陶瓷雾化片雾化后产生粒径较大的烟雾分子时，其可以喷到另外一个陶瓷雾化片表面上并被再次雾化，从而使得粒径较大的烟雾分子变成粒径较小的烟雾分子，烟雾口感更佳细腻。
