具体实施方式
体现本发明特征与优点的典型实施方式将在以下的说明中详细叙述。应理解的是本发明能够在不同的实施方式上具有各种的变化，其皆不脱离本发明的范围，且其中的说明及图示在本质上是当作说明之用，而非用以限制本发明。
在本申请的描述中，需要理解的是，在附图所示的实施例中，方向或位置关系的指示(诸如上、下、左、右、前和后等)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。当这些元件处于附图所示的位置时，这些说明是合适的。如果这些元件的位置的说明发生改变时，则这些方向的指示也相应地改变。
此外，术语“第一”、“第二”仅用于描述目的，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”的特征可以明示或者隐含地包括一个或者更多个所述特征。在本申请的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
请参阅图1，本实施例为一种喷雾芯100，包括外壳110、活动件120和插针130。喷雾芯100主要用于注氧仪、喷雾器等设备上，利用供气装置所提供的气体将供液装置所提供的液体分散成微小液滴并向外喷出。
请参阅图1和图3，外壳110内部设有容纳腔111，且一端开设有与容纳腔111连通的雾化口112。活动件120可活动地设置在容纳腔111内，活动件120可朝向或背向雾化口112往复运动。活动件120内部设有空腔121，活动件120靠近雾化口112的一端开设有与容纳腔111连通的喷水口122。插针130插设在空腔121内，且长度方向与活动件120的活动方向一致，插针130的第一端固定设于外壳110上，第二端可插入喷水口122内。
以喷雾芯100未进行喷雾作业的状态也初始状态，在初始状态下，活动件120远离雾化口112、且靠近插针130，此时插针130的第二端插设在喷水口122内以封堵喷水口122。
请参阅图1，喷雾芯100进行喷雾作业的过程为：活动件120朝向雾化口112移动时，插针130的第二端未插设在喷水口122内；此时空腔121和容纳腔111通过喷水口122连通。供液装置通过液路向空腔121内提供液体，液体再通过喷水口122流出。供气装置通过气路118向容纳腔111内泵入气体。从喷水口122流出的液体被气体从雾化口112中吹出，以形成气雾。
请参阅图2，喷雾芯100停止喷雾作业的过程为：活动件120向背离雾化口112移动，此时活动件120上的喷水口122不断靠近插针130的第二端；当活动件120移动到一定位置后，插针130的第二端插设在喷水口122内。因此喷水口122被插针130堵塞，空腔121内的液体无法流向容纳腔111和雾化口112。此时供气装置可停止向容纳腔111输送气体，供液装置也可停止向空腔121输送液体。
通过上述对喷雾芯100两个作业状态的介绍，可以知悉：活动件120可活动地设置在容纳腔111内，利用活动件120和插针130的配合来堵塞或疏通喷水口122进而控制喷雾芯100的作业状态。在喷雾芯100不使用时，如果没有插针130插设在喷水口122内，会使液体长期停留在喷水口122，而如果是高浓度的液体(如化妆液)，则会发生凝固、导致喷水口122堵塞。因此，本实施例提供的喷雾芯100，在不使用时可通过插针130对喷水口122进行封堵，有效防止液体长期停留并凝固在喷水口122内造成堵塞。在喷雾 芯100使用结束时，由于活动件120的活动，使得插针130的第二端插入喷水口122内，此动作可以对残留在喷水口122上的液体进行清理，进一步防止喷水口122堵塞。因此喷雾芯100可以有效解决喷水口122堵塞的问题，提高了用户的使用体验。
喷雾芯100还包括用于带动活动件120朝向或背向所述雾化口112往复运动的驱动组件14。活动件120的移动可以是手动或者电动，采用不同的方式，驱动组件14的构成和结构则不相同。
请参阅图3，驱动组件14包括电机140，电机140的输出端上安装有蜗杆150。活动件120的外侧壁上设有螺牙123，螺牙123沿活动件120的活动方向延伸，且螺牙123与蜗杆150啮合。电机140正转时，通过输出端带动蜗杆150正向转动，蜗杆150和螺牙123啮合，因此蜗杆150的正向转动可带动活动件120朝向雾化口112运动。电机140反转时，通过输出端带动蜗杆150反向转动，蜗杆150和螺牙123啮合，因此蜗杆150的反向转动可带动活动件120背向雾化口112运动。当然，在其他实施方式中，可通过调整使电机140正转时，活动件120背向雾化口112运动；电机140反转时，活动件120朝向雾化口112运动。通过设置驱动组件14可实现活动件120往复运动的自动化。采用电机140、蜗杆150和螺牙123作为驱动结构，通过电机140的正反转即可实现活动件120往复运动，整体结构较为简单、紧凑；而且传动平稳、无噪音。
在其他实施方式中，可采用人工驱使活动件120往复移动，如设置手柄连接活动件120，使用者通过往不同方向推动手柄即可驱使活动件120往复移动。
在其他实施方式中，还可以采用气缸等其他装置代替电机140来驱使活动件120往复移动。
请参阅图3，喷雾芯100还包括螺钉190。螺钉190的一端穿过外壳110与插针130螺纹连接，螺钉190与外壳110螺纹连接；拧动螺钉190时，可使插针130相对螺钉190朝向或背向喷水口122移动。
插针130在远离喷水口122的一端开设有螺纹孔，外壳110在安装螺钉190的位置处也开设有螺纹孔。螺钉190上的螺杆穿过外壳110上的螺纹孔拧入插针130上的螺纹孔内，且螺钉190同时与外壳110上的螺纹孔和插针 130上的螺纹孔螺纹连接。顺时针拧动螺钉190时，插针130由于与活动件120有连接关系，因此插针130相对螺钉190朝向喷水口122移动，此时插针130插设在空腔121内的深度变深。逆时针拧动螺钉190时，插针130则相对螺钉190背向喷水口122移动，此时插针130插设在空腔121内的深度则变浅。通过拧动螺钉190即可调整插针130插入空腔121的深度，以此调节插针130对喷水口122的插入深度，保证插针130能完全疏通或堵塞喷水口122；不仅能防止喷水口122被粘稠的液体堵塞，还能防止在不使用时出现漏液的情况。应当注意的是，在其他实施方式中，可通过设置螺纹的旋向，使顺时针拧动螺钉190时，插针130背向喷水口122移动；逆时针拧动螺钉190时，插针130朝向喷水口122移动。
请参阅图3，外壳110的一端开设有用于收纳螺钉190头部的沉槽116。当螺钉190与外壳110和插针130连接固定后，螺钉190的头部置于沉槽116内。通过设置沉槽116收纳螺钉190的头部，可使整体结构更加紧凑、合理，且能防止出现不小心转动螺钉190的情况。
在其他实施方式中，插针130插入空腔121的深度的调整可采用其他方式，如直接采用人工手动推进或拉出插针130，或将插针130设置为可伸缩的形式。
请参阅图3，外壳110包括壳体114和后盖115。壳体114为内部中空、一端开口的近似圆柱状结构，其中内部中空形成的上述的容纳腔111，壳体114不开口的一端开设有上述的雾化口112，开口的一端安装有后盖115。插针130的一端具体固定于后盖115上。外壳110的结构如此设置可方便活动件120、插针130的安装，且喷雾芯100整体结构组装也更加方便。后盖115相对壳体114可拆卸设置，方便后续对活动件120、插针130进行拆卸、清洗、更换。
请参阅图3，壳体114上开设有与容纳腔111连通的进液接口117，进液接口117用于与供液装置连接。在活动件120上开设有进液口127，进液口127的位置与进液接口117的位置相对应，且进液口127分别与进液接口117和活动件120内的空腔121连通。供液装置的液体依次通过进液接口117和进液口127流入空腔121内。由于活动件120可相对外壳110往复运动，因此将进液口127的长度设计为不小于进液接口117的长度与活动件120的最 大活动距离之和，使得活动件120在活动时，进液口127均能覆盖进液接口117，保证从供液装置流出的液体能顺利进入空腔121内。
请参阅图3，活动件120包括活动体124和端盖125。活动体124为内部中空、一端开口的近似圆柱状的结构，其中内部中空形成上述的空腔121，上述的进液口127具体开设在活动体124的侧壁上，上述的螺牙123具体设置在活动体124远离进液口127一侧的侧壁上。活动体124不开口的一端朝向雾化口112、且开设有喷水口122。端盖125安装在活动体124开口的一端，且插针130的一端穿过端盖125插设在空腔121内。活动件120的结构如此设置可方便插针130的安装，且端盖125相对活动体124可拆卸设置，方便后续对活动件120、插针130进行拆卸、清洗、更换。
请参阅图3，端盖125的外侧壁上开设有定位槽126，定位槽126的长度方向与活动件120的移动方向一致。壳体114上开设有定位孔113，定位孔113内穿设有定位销160，定位销160的一端可滑动地插设于定位槽126内。定位销160相对壳体114固定，当活动件120在容纳腔111内活动时，活动件120则相对定位销160移动，使得定位销160的一端在定位槽126内滑动。设置定位销160和定位槽126，可对活动件120的活动进行引导和限位，防止活动件120在移动时产生偏移。
请参阅图3，端盖125上套设有第一密封圈170，当端盖125安装在活动体124上时，第一密封圈170密封抵接与端盖125和活动体124的连接处，使得端盖125和活动体124可紧密连接，既能提高结构的稳定性，又能防止空腔121内的液体泄漏。
如前面，插针130的一端穿过端盖125插设在空腔121内，因此插针130还与端盖125连接；但是端盖125和插针130可相对活动，即活动件120活动时，插针130可处于固定不动的状态。在此结构上，既要满足插针130和端盖125相对活动，又要防止插针130和端盖125之间缝隙过大造成空腔121内的液体泄漏。因此，请参阅图3，在插针130上套设有第二密封圈180，第二密封圈180密封抵接于端盖125与插针130的连接处，使端盖125和插针130贴合紧密，空腔121内的液体不易从两者之间的缝隙中泄出。
本实施例为一种注氧仪，包括主体、供液装置、供气装置和喷雾芯100，喷雾芯100安装在主体上，供液装置通过液路与空腔121连通并向空腔121 输送液体，供气装置通过气路118与容纳腔111连通并向容纳腔111提供气体。供液装置所输送的液体可以是化妆液、美容液、护肤液等。供液装置可以是装载有液体的容量瓶，将该容量瓶的开口与进液接口117连接、并固定在外壳110上，即可使供液装置自动向空腔121内提供液体。供气装置可以设置在主体上，通过主体的控制使供气装置向容纳腔111内提供气体。供气装置可以采用高压气源，也可以采用可以促进空气流动的风机等。注氧仪使用了上述的喷雾芯100，因此兼具了上述关于喷雾芯100的有益效果，在此不一一赘述。
虽然已参照几个典型实施方式描述了本发明，但应当理解，所用的术语是说明和示例性、而非限制性的术语。由于本发明能够以多种形式具体实施而不脱离发明的精神或实质，所以应当理解，上述实施方式不限于任何前述的细节，而应在随附权利要求所限定的精神和范围内广泛地解释，因此落入权利要求或其等效范围内的全部变化和改型都应为随附权利要求所涵盖。
