在本申请的描述中，术语“上”、“下”、“轴向方向”方位为基于附图4所示的方位。需要理解的是，这些方位术语仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。术语“第一/第二”仅仅是是区别不同的对象，不表示二者之间具有相同或联系之处。
本申请实施例的一方面提供一种流量调节组件100，请参阅图1至图4，包括套壳1和调节件2。
套壳1内形成有主流道1a；套壳1的轴向的一侧壁形成有第一流口1b，套壳1的周侧壁形成有第二流口1c，第一流口1b和第二流口1c均与主流道1a连通。具体地，以图4中的视角为例，套壳1大致为中空的管状结构，轴向方向与上下方向相同，第一流口1b和第二流口1c均可用于对接管道，液态介质能够从第一流口1b流入主流道1a内，从并从第二流口1c流出。或者，液态介质也能够从第二流口1c流入主流道1a内，从并从第一流口1b流出。
调节件2的至少部分设置于主流道1a内，调节件2绕套壳1的轴向转动，以调节第一流口1b进入主流道1a内的流量。也就是说，调节件2能够部分设置于主流道1a内，也可以完全设置于主流道1a内。示例性的，调节件2的下端设置于主流道1a内，并可绕套壳1的轴向方向转动，调节件2在转动过程中，能够完全封闭第一流口1b或改变第一流口1b的出液面积，从而调节第一流口1b进入主流道1a内的流量。
流量调节组件100可用于电子雾化装置1000。以本申请实施例的流量调节组件100用于电子雾化装置1000上为例，请参阅图8，本申请另一方面提供一 种电子雾化装置1000，包括气泵200、雾化腔210、储液腔220、供气通道230、供液通道240以及本申请实施例所述的任意一项的流量调节组件100。
气泵200通过供气通道230为雾化腔210供气，储液腔220通过供液通道240为雾化腔210供液，气流与雾化液在雾化腔210内相遇混合以形成雾化液滴；流量调节组件100设置于供液通道上，第一流口1b与储液腔220连通，第二流口1c与雾化腔210连通，以调节供液通道的流量。具体地，电子雾化装置1000还包括具有雾化腔210的雾化组件以及具有储液腔220的储液仓组件，储液腔220用于容纳和储存雾化液，雾化液包括但不限于为药液、美容液、烟液等液态介质，也就是说，电子雾化装置1000可以用于美容雾化领域、药液雾化领域以及烟液雾化领域。雾化液在雾化腔210内进行雾化处理，供液通道240用于将储液腔220内的雾化液导入至雾化腔210内。供气通道240的两端分别连通雾化腔210和气泵200的泵气口，以将气泵200泵出的气流输送至雾化腔210内，第一流口1b与储液腔220连通，第二流口1c与雾化腔210连通，用户在使用中可以通过控制流量调节组件100调节从供液通道240流入雾化腔210内雾化液的流量，以改变雾化组件的出雾量，提高了用户的使用体验。
一实施例中，请参阅图9，电子雾化装置1000还包括加热器250，气流与雾化液在雾化腔210内相遇混合后形成的雾化液滴从雾化腔210内喷出，加热器250能够对雾化腔210内喷出的雾化液滴进一步加热雾化形成颗粒粒径更小的气溶胶，特别是当雾化液为药液、烟液时，经过加热器250二次雾化后可进一步提高用户的使用体验。
本申请实施例提供的一种流量调节组件100，一方面具有调节件2和套壳1，调节件2仅需绕套壳1的轴向转动，即可直接调节第一流口1b进入主流道1a内的流量，相比复杂的结构需要使用更多的能源和时间来调节而言，本申请的流量调节组件100整体结构简单紧凑，流量调节变化更加线性流畅，流量调节的相应时间更短，流量调节组件100的工作可靠性高。另一方面，流量调节组件100可设置于电子雾化装置1000的供液流道上，用户在使用中可以通过控制流量调节组件100调节从供液通道流入雾化腔内雾化液的流量，使得供液流量 与雾化组件的加热功率之间处于合理范围，实现了电子雾化装置1000对流量调节的主动控制，雾化后生成的气溶胶品质更稳定，提高了用户的使用体验。
一实施例中，图4至图7，调节件2具有全关位和全开位，在调节件2处于全关位的状态下，调节件2封闭第一流口1b；在调节件2处于全开位的状态下，第一流口1b的出液面积达到最大；调节件2在全关位和全开位之间连续转动，以调节第一流口1b的出液面积。也就是说，在调节件2相对套壳1沿轴向在全关位和全开位之间连续转动的情况下，第一流口1b的出液面积将随着调节件2的转动而连续改变，因此本申请的流量调节组件100可实现对流量的无极调节。
一实施例中，请参阅图5至图7，调节件2朝向第一流口1b的一端的部分周向面形成通流槽2a，调节件2朝向第一流口1b的端面为调节面2b；在调节件2处于全开位的状态下，调节面2b与第一流口1b的至少部分错位，在调节件2处于全关位的状态下，调节面2b封闭第一流口1b。
具体地，调节件2为杆状结构，通流槽2a用于连通第一流口1b，调节面2b用于调节第一流口1b的出液面积，套壳1形成有第一流口1b的轴向一端为过流板121，调节件2的调节面2b抵接于过流板121上，调节件2沿周向转动的过程中，调节面2b能够完全封闭第一流口1b或部分封闭第一流口1b或完全与第一流口1b错位，从而连续改变第一流口1b的出液面积。在调节件2处于全开位的状态下，在与套壳1轴向垂直的投影面上，第一流口1b流入通流槽2a的出液面积达到最大；在调节件2处于全关位的状态下，调节面2b完全封闭第一流口1b。
第一流口1b的形状不做特别的限定，第一流口1b可以是圆形、椭圆形、方形、多边形等等。一实施例中，请参阅图5，在与套壳1轴向垂直的投影面上，第一流口1b的投影呈沿周向延伸的弧形。第一流口1b呈弧形结构，可以使得调节件2每次转动预设角度的情况下，第一流口1b的出液面积每次改变的变化量保持稳定，用户可以根据调节件2的转动角度准确地确定第一流口1b当前的出液面积。示例性的，一实施例中，弧形的弧度范围为120°～180°。 具体地，弧形的弧度范围可以取120°、130°、140°、150°、160°、170°、180°等数值。
一实施例中，请参阅图5至图7，在与调节杆轴向垂直的投影面上，通流槽2a的投影呈扇形。每次转动预设角度的情况下，扇形的半径边与第一流口1b的弧形结构配合，能够均匀地改变第一流口1b的出液面积，使得第一流口1b的出液面积每次改变的变化量保持稳定，进一步保证通过调节件2的转动角度能够准确地确定第一流口1b当前的出液面积，实现供液流量的精准调节。示例性的，一实施例中，扇形的角度范围为100°～150°。具体地，扇形的角度范围可以取100°、110°、120°、130°、140°、150°等数值。
一实施例中，第一流口1b的内弧边1ba的半径为0.5mm～0.7mm。具体地，内弧边1ba的半径可以取0.5mm、0.6mm、0.7mm。一实施例中，第一流口1b的外弧边1bb的半径为0.9mm～1.1mm。具体地，外弧边1bb的半径可以取0.9mm、1.0mm、1.1mm。
由于流体能够通过第一流口1b的内弧边1ba与第一流口1b的外弧边1bb之间的间隙中通过，当内弧边1ba与外弧边1bb之间的间隙越大，调节件2每次转动预设角度第一流口1b的出液面积的变化越大，当内弧边1ba与外弧边1bb之间的间隙越小，调节件2每次转动预设角度第一流口1b的出液面积的变化越小。因此，合理设置内弧边1ba和外弧边1bb的尺寸，可有效调整调节件2每次转动预设角度的情况下第一流口1b的出液面积的变化量。
本申请实施例提供的流量调节组件100，通过合理设置第一流口1b、调节面2b以及通流槽2a的形状及尺寸参数，可实现在不大于0.1ml/s的流量范围下实现精确调节。
一实施例中，请参阅图3和图4，流量调节组件100包括弹性件3，弹性件3的两端分别连接套壳1和调节件2，以使调节件2与套壳1形成有第一流口1b处的轴向侧壁保持抵接。也就是说，弹性件3产生的弹性力将使得调节面2b时刻抵接于过流板121上，可避免调节件2绕套壳1转动的过程中产生沿轴向上的滑动，从而防止调节面2b与过流板121沿轴向分离后，第一流口1b与主 流道1a直接导通的情况发生，保证流量调节组件100的工作可靠性。
弹性件3的结构形式不做特别的限定，弹性件3包括但不限于是弹簧、弹片、波纹管等具有可恢复形变的弹性结构。示例性的，一实施例中，请参阅图3和图4，套壳1包括套盖11和套筒12，套筒12内形成有主流道1a，套筒12的轴向两端形成有第一流口1b和安装口1d，调节件2靠近第一流口1b的一端通过安装口1d伸入主流道1a内，套盖11盖设于安装口1d上，调节件2的周侧壁形成有台阶面2c，弹性件3的两端分别连接套盖11和台阶面2c。具体地，套盖11和套筒12的连接方式不做特别的限定，包括但不限于卡接、螺栓螺钉连接、焊接、胶接等方式，示例性的，一实施例中，请参阅图X，套盖11包括盖设于安装口1d处的盖板111和围设于盖板111外周侧的围板112，围板112的内周壁形成有内螺纹和套筒12的外周壁形成有外螺纹，围板112与套筒12螺纹套接。套盖11和套筒12采用螺纹套接的方式，能够方便调节件2和弹性件3的拆装与维护。弹性件3可以是套设于调节件2上压缩弹簧，当弹性件3的两端分别连接盖板111的下端面和台阶面2c，以使调节件2与过流板121保持抵接。示例性的，一实施例中，套筒12的内径介于3mm～7mm；和/或，套筒12沿轴向上的高度为14mm～20mm。
调节件2绕套壳1轴向方向转动的形式不做特别的限定，使用者可以手动施加绕套壳1轴向方向转动的作用力以操作调节件2转动，也可以通过机械传动的方式例如螺纹配合、齿轮配合等方式操作调节件2转动，还可以通过电机驱动等方式控制调节件2转动。
示例性的，一实施例中，请参阅图1和图4，调节件2远离第一流口1b的一端伸出主流道1a并形成有用于与工具配合的操作部21。具体地，套盖11的盖板111上形成有通孔111a，操作部21通过通孔111a伸出主流道1a。操作部21用于提供工具操作调节件2转动的施力点，用户可直接通过工具与操作部21配合，手动转动调节件2。或者也可以将操作部21直接与电机适配，通过电机电动驱动调节件2转动。操作部21的结构形式不做特别的限定，请参阅图1，操作部21为形成于调节件2外周壁上的平台面。类似的，操作部21还可以设 置为齿形面或其他与手动或电动操作工具适配的异形面。
一实施例中，请参阅图3和图4，调节件2为圆柱形结构，调节件2包括第一杆段22和第二杆段23，第一杆段22的一端形成有调节面2b和通流槽2a，第一杆段22的另一端与第二杆段23连接，第一杆段22与第二杆段23之间形成有台阶面2c，第二杆段23远离第一杆段22的一端形成有操作部21。具体地，第一杆段22用于调节第一流口1b处的流量，第二杆段23用于套设弹性件3并驱动第一杆段22转动，如此设置，可使得加工调节件2时，仅需保证第一杆段22的加工精度即可实现流量的精细调节，从而降低调节件2整体的加工成本和加工难度。示例性的，一实施例中，第一杆段22沿套壳1轴向上的高度为5mm～10mm；和/或，第一杆段22的外径为2.9mm～6.9mm；和/或，第二杆段23沿套壳1轴向上的高度为15mm～20mm；和/或，第二杆段23的外径为3mm～5mm。

示例性的，一实施例中，请参阅图3和图4，第一连接头41远离第一流口1b的一端的外周壁形成有导向部4a，和/或，第二连接头42远离第二流口1c的一端的外周壁形成有导向部4a。具体地，导向部4a包括但不限于为倒斜角或倒圆角。导向部4a能够进一步便于外部管路的装配和对接。

示例性的，一实施例中，请参阅图3和图4，调节件2的外周壁和主流道1a的内周壁二者其中之一形成有限位环槽2d，密封件5嵌设于限位环槽2d内。也就是说，限位环槽2d可以设置于调节件2上，也可以设置有主流道1a的内周壁上，限位环槽2d用于限定密封件5在调节件2绕套壳1轴向转动过程中的相对位置，防止密封件5在调节件2转动过程中沿轴向发生滑动，避免密封件5脱落，提高密封件5的密封可靠性。
