Description
本申请涉及将可雾化基质雾化后输入人体的技术领域,尤其涉及一种雾化组件、具有上述雾化组件的雾化器及具有上述雾化器的可吸入装置。
可吸入装置通常包括雾化器和供电装置。雾化器可通过雾化的手段对液态可雾化基质进行加热,使其生成雾化气体以供使用者吸食。供电装置用于向雾化器进行供电。现有雾化器的雾化芯通常包括加热丝和包裹在加热丝外的吸液件。当储液件向吸液件供液后,加热丝对吸液件上的烟液进行加热。
然而,当储液件向吸液件供液后,吸液件中的液体存在利用率低的情况。其次,储液件储液时容易发生泄露,损坏内部的电路板和电池等电子元器件,而且引起储液件贮液量的减少,从而影响产品最大口数。再次,当储液件的供液量和供液速率赶不上加热效率时,加热丝会直接加热干燥的吸液件,使得吸液件发生“糊芯”现象而发出糊味。
发明内容
为解决以上不足之处,有必要提供一种雾化组件、雾化器及可吸入装置。
本申请提供一种雾化组件,包括芯壳和导液部件。芯壳界定出一容置腔,芯壳上还设有与容置腔连通的第一槽。导液部件包括第一导液部和第二导液部,第一导液部位于容置腔内,第二导液部一体连接于第一导液部,且经第一槽伸出容置腔并用于连接一储液部件。

请参阅图1至图5,本申请一实施方式提供一种雾化组件100,包括底座部件10、发热部件20和导气部件30。发热部件20设于底座部件10和导气部件30之间。发热部件20包括芯壳21、导液部件22和发热器23。导液部件22用于将一储液部件40(在图7和图8中示出)中存储的可雾化基质引导或输送至芯壳21内。可雾化基质中包括目标活性成分。发热器23设于芯壳21内且与导液部件22接触,发热器23用于对导液部件22中的可雾化基质进行加热雾化,从而得到气溶胶。导气部件30用于将气溶胶导出,从而供使用者吸食。
在一些实施例中,储液部件40为一体式结构的储液棉,储液棉能够存储较大量(超 过10mL)的可雾化基质,从而使储液部件40能够满足使用者对大剂量目标活性成分的使用需求,而且还使得可雾化基质稳定地吸附并存储于储液棉中,降低可雾化基质的流动性,减少泄露风险,从而满足随身携带的需求并提高雾化组件100的使用寿命。
芯壳21横截面可大致呈圆环形并界定出一容置腔S。芯壳21上还开设有与容置腔S连通的第一槽211。导液部件22为一体式结构,包括第一导液部221和两个第二导液部222。第一导液部221位于容置腔S内。第一导液部221横截面大致呈圆弧形设置并界定出一第一流道2210,第一导液部221包括相对设置的第一侧边2211和第二侧边2212。两个第二导液部222分别连接第一导液部221的第一侧边2211和第二侧边2212,且经第一槽211伸出容置腔S并连接储液部件40。两个第二导液部222相互层叠,两个第二导液部222远离彼此的表面作为第二导液部222与储液部件40接触的接触面2220,使得储液部件40中所存储的可雾化基质可经上述接触面2220引导或输送至芯壳21内的第一导液部221。发热器23位于容置腔S内,且与第一导液部221的内表面接触。在一些实施例中,芯壳21的材质可以为可抗强冲击的聚碳酸酯(PC)。
如此,当储液部件40中所存储的可雾化基质经导液部件22的第二导液部222引导或输送至芯壳21内部的第一导液部221时,设于第一导液部221的内表面的发热器23可开始对第一导液部221中的可雾化基质进行加热,从而得到可供使用者吸食的气溶胶。在本申请具体的实施例中,可将一张平整的导液部件22在中间位置处进行弯曲以得到第一导液部221,而两端的部分则形成第二导液部222。在一些实施例中,第一槽211可由芯壳21远离底座部件10的上端部开始朝向靠近底座部件10的下端部的方向开设,且第一槽211并未贯穿芯壳21的下端部。
如图2和图3所示,在一些实施例中,芯壳21上还可设有与容置腔S连通的第二槽212。第一导液部221还通过第二槽212与储液部件40连通,使得储液部件40中所存储的可雾化基质还可经第二槽212输送至第一导液部221中。即,储液部件40中所存储的可雾化基质不仅可经第一槽211输送至芯壳21内的第一导液部221中,而第二槽212作为进液槽,使得储液部件40中所存储的可雾化基质同样可经第二槽212输送至第一导液部221。在一些实施例中,第二槽212可开设于芯壳21的上端部和下端部之间,第二槽212的表面积小于第一槽211的表面积。
现有技术中导液部件包括设于芯壳内的第一圈导液棉和包覆于芯壳外部的第二圈导液棉,第二圈导油棉连通储液腔,储液腔中的液体沿第二圈导油棉、芯壳上开设的进液槽 以及第一圈导油棉进行输送。本申请将现有技术中设于芯壳外圈的第二圈导油棉减掉并设置导液部件22包括第一导液部221和第二导液部222,第二导液部222经第一槽211伸出芯壳21并连接储液部件40,如此,储液部件40中所存储的可雾化基质可经第二导液部222输送至芯壳21内的第一导液部221中。而且,由于本申请减掉现有技术中设于芯壳外圈的第二圈导油棉,导液路径变短,有利于导液部件22中可雾化基质的利用率,提高产品的最大口数。可以理解,在储液部件40存储较大量的可雾化基质的前提下,即便采用从储液部件40经第二导液部222输送至第一导液部221这种单一方式,也能够保证导液部件22持续地具有充足的液体。
再者,当芯壳21上还设有第二槽212时,储液部件40中所存储的可雾化基质还可经第二槽212输送至第一导液部221中,提高了从储液部件40到第一导液部221的导液量,使得导液部件22持续地具有充足的液体,能够耐受发热器23在雾化过程中产生的高温(通常超过300摄氏度)。
其中,储液部件40为中空结构且用于套设于发热部件20的外侧壁。在一些实施例中,储液部件40的外径为17mm~25mm,内径为4mm~5mm,高度为20mm~40mm。储液部件40的孔隙率为3.5%~8%。导液部件22的密度为60g/cm
3~85g/cm
3。请参阅图4和图5,进一步地,导液部件22为多层结构,其包括层叠设置的第一层2201和第二层2202,第一层2201数量为1或2层,第一层2201的纹路方向平行于第一流道2210的中心轴O(可称为竖纹);第二层2202数量为1至3层,且第二层2202的纹路方向垂直于第一层2201的纹路方向(可称为横纹)。其中,导液部件22中最靠近发热器23的为第一层2201,即可雾化基质的纵向流动速度大于横向流动速度,从而增加第一层2201中可雾化基质的含量,使得导液部件22中最靠近发热器23的部分具有充足的液体,能够耐受发热器23在雾化过程中产生的高温。
导液部件22中除最靠近发热器23的为第一层2201之外,导液部件22中其它层可按照任意顺序层叠设置。在一些实施例中,导液部件22中最远离发热器23的为纹路方向垂直于第一流道2210的中心轴O的第二层2202,使得导液部件22中最远离发热器23的部分具有纵向锁液能力,防止可雾化基质下串而出现泄露风险。
在一些具体的实施例中,导液部件22可以为导液棉,导液部件22的第一层2201为亚麻棉,第二层2202为木浆棉。
由于在雾化过程中,储液部件40主要起存储可雾化基质的作用(即“锁液作用”),而导液部件22主要起引导或输送可雾化基质的作用(即“输液作用”),本申请通过设置储液部件40的尺寸和孔隙率,以及与之匹配的导液部件22的密度和结构组成,使得锁液作用与输液作用之间建立起良好的平衡状态,避免雾化组件100由于供液不足而发生干烧,进而产生糊味甚至糊芯的不良雾化效果,且可使得产品具有较高的最大口数。再者,设置导液部件22中最靠近发热器23的为纹路方向平行于第一流道2210的中心轴O的第一层2201,使得导液部件22中最靠近发热器23的部分能够耐受发热器23在雾化过程中产生的高温,从而进一步避免糊芯。
在一些实施例中,发热器23可以为加热网。相较于加热丝而言,加热网与可雾化基质之间具有更大的接触面积,使得加热更加均匀。而且,相较于加热丝而言,加热网具有更小的电阻变化量。在一些具体的实施例中,加热网的材质可以为不锈钢。
在另一些实施例中,发热器23还可包括两个加热网,两个加热网沿垂直于第一流道2210的中心轴O的方向层叠设置。通过设置两个加热网,可进一步提高加热的均匀性。
如图2至图5所示,在一些实施例中,导气部件30包括导气管31和第一密封件32。导气管31用于界定出一与第一流道2210连通的第二流道310,且导气管31通过第一密封件32密封连接于芯壳21的上端部。第一密封件32用于密封芯壳21的上端部与导气管31之间的间隙,防止产生的气溶胶经芯壳21的上端部与导气管31之间的间隙向外泄露。在一些具体地实施例中,第一密封件32包括第一密封部321、连接第一密封部321的第二密封部322以及自第一密封部321和第二密封部322的连接处向外凸出形成的第一凸缘323。第一密封部321密封连接于导气管31朝向所述底座部件10的下端部内,且导气管31的下端部抵持于第一凸缘323的一表面。第二密封部322密封连接于芯壳21的上端部,且芯壳21的上端部抵持于第一凸缘323的另一表面。第一密封部321和第二密封部322中设有贯穿的第一导气孔3210,使得加热后产生的气溶胶可经过第一流道2210以及第二密封部322和第一密封部321的第一导气孔3210后,再经导气管31的第二流道310导出。在一些具体地实施例中,导气管31可以为耐高温的玻纤管,如硅树脂玻纤管。
如图2至图5所示,底座部件10包括底座11和第二密封件12,芯壳21的下端部通过第二密封件12密封连接于底座11。在一些具体的实施例中,底座11包括底座本体111和自底座本体111的外侧壁向外凸出形成的第二凸缘112。第二密封件12套设于底座本体111的顶面和外侧壁且抵持于第二凸缘112的一表面。底座本体111的顶面开设有盲槽 1110,芯壳21的下端部穿过第二密封件12并伸入盲槽1110中。第二密封件12用于密封芯壳21的下端部与底座本体111之间的间隙,防止加热产生的气溶胶经芯壳21的下端部与底座本体111之间的间隙向外泄露。在一些具体的实施例中,第一密封件32和第二密封件12的材质可以为硅胶。
请参阅图6至图8,本申请另一实施方式还提供一种雾化器200,包括储液部件40、吸嘴50、储液管60和上述任一实施例或实施例组合的雾化组件100。
储液部件40和雾化组件100均设于储液管60内,即储液管60能够起到整体封装固定的作用。储液部件40套设于雾化组件100的发热部件20的外侧壁且抵持于底座部件10的上表面。其中,储液部件40设有缺口41(在图10中示出),导液部件22的第二导液部222可设于缺口41内。吸嘴50固定于储液管60的上端部。吸嘴50中开设有吸气口500,吸气口500与导气管31的第二流道310连通。在一些具体的实施例中,吸嘴50包括安装部51和吸食部52。安装部51安装于储液管60上端部的外侧壁。吸食部52连接安装部51,且位于储液部件40远离底座部件10的一端。使用者可通过在吸食部52处吸气,使得加热后产生的气溶胶经导气管31导出,并在通过吸气口500被使用者吸食。在一些具体的实施例中,储液管60的材质为可耐冲击的聚碳酸酯,吸食部52的形状可采用满足人体工学的圆形、椭圆形、鸭嘴型等。
如图7和图8所示,在一些实施例中,吸嘴50内可设有第一吸液棉53,且第一吸液棉53设于吸食部52和储液部件40之间。第二吸液棉用于吸收从储液部件40处溢出的可雾化基质,从而减小泄露的风险。
进一步地,吸嘴50内还可设有第三密封件54,且第三密封件54设于第一吸液棉53和储液部件40之间。第三密封件54用于密封储液管60与吸嘴50之间的间隙,防止从储液部件40处溢出的可雾化基质经储液管60与吸嘴50之间的间隙发生泄露。
如图7和图8所示,在一些实施例中,吸嘴50内还可设有第四密封件55。第四密封件55可拆卸地设于吸气口500中,防止使用者不使用雾化器200时外部灰尘或水汽进入吸气口500中。
如图7和图8所示,在一些实施例中,雾化器200还可包括第二吸液棉13和控制板14。第二吸液棉13设于底座部件10的底座本体111的下表面,且底座部件10的第二凸缘112可围绕第二吸液棉13的外侧壁设置。第二吸液棉13用于吸收从储液部件40或导液部件22处溢出的可雾化基质,从而减小泄露的风险。控制板14设于第二吸液棉13远离底 座本体111的表面且与发热器23电性连接。发热器23的引脚230穿过底座部件10并与控制板14电连接。请一并参照图4、图5和图8,在一些具体的实施例中,底座部件10的第二凸缘112的底面设有至少两个朝内的卡勾113。卡勾113用于将控制板14卡持固定于底座部件10内。
请参阅图9至图12,本申请另一实施方式还提供一种可吸入装置300,包括外壳70、供电部件80和上述任一实施例或实施例组合的雾化器200。在一些实施例中,可吸入装置300可以为电子烟,即可雾化基质为烟油。在另一些实施例中,可吸入装置300并不限于电子烟,还可以是用于将可雾化基质雾化成气溶胶供使用者吸食的其它雾化器。例如,可吸入装置300还可以是将液体雾化后输入人体的器械设备,如用于治疗上呼吸道疾病的医疗雾化吸入器。此时,可雾化基质可为治疗上呼吸道疾病对应的药液。依靠病人呼吸,将药液雾化后形成的药雾吸入人体呼吸道直至肺泡,从而用于上呼吸道局部药物治疗。
雾化器200和供电部件80均设于外壳70内,且雾化器200的吸嘴50凸出于外壳70。外壳70固定于雾化器200的吸嘴50,具体地,外壳70固定于吸嘴50的安装部51。供电部件80设于雾化器200设有控制板14的一侧且电连接于控制板14,从而,控制板14可控制供电部件80向发热器23供电,进而使发热器23对可雾化基质进行加热。在一些实施例中,吸嘴50的安装部51远离吸食部52的下端部设有一圈卡槽510。外壳70的上端部可通过胶粘剂(图未示)固定于卡槽510中。在其它实施例中,外壳70和吸嘴50还可通过磁性吸附或过盈配合等方式相互固定。在一些具体的实施例中,外壳70和吸嘴50的安装部51的横截面均为八边形。可以理解,在其它实施例中,外壳70和吸嘴50的安装部51的具体形状也可以根据实际需求进行设置。在一些实施例中,供电部件80可以为圆柱形的电池。
如图10至图12所示,在一些实施例中,可吸入装置300还可包括气流传感器81和安装座82。气流传感器81和安装座82均设于外壳70内,气流传感器设于供电部件80远离雾化器200的一端供电部件80。外壳70远离吸嘴50的底端开设有进气口71,气流传感器81与进气口71气流连通(如,供电部件80与外壳70之间可设有缝隙,使得气流传感器81通过该缝隙与进气口71气流连通)。安装座82套设于气流传感器81外侧壁,用于将气流传感器81安装于外壳70中。当使用者通过吸嘴50吸气时,进气口71内的气流使气流传感器81启动,此时控制板14控制供电部件80为发热器23供电。在一些具体的实施例中,气流传感器81为咪头,安装座82的材质可以为硅胶。
在一些实施例中,控制板14朝向供电部件80的表面设有发光器(如LED等)。当气流传感器81感测到使用者通过吸嘴50吸气时,发光器开始发光。如图10至图12所示,可吸入装置300还可包括铝箔纸90、反光纸91和导光支架92。铝箔纸90、反光纸91和导光支架92的截面均可呈环形。导光支架92的下端部固定于安装座82上,且导光支架92可套设于供电部件80外。铝箔纸90固定于导光支架92的上端部,且围绕控制板14设置。反光纸91设置于供电部件80与导光支架92之间。外壳70可采用透光材质制成。当发光器发光时,铝箔纸90、反光纸91和导光支架92用于对发光器发出的光线进行扩散,使得外壳70产生发光效果,提高使用者体验。
在一些实施例中,可吸入装置300还可包括套设于外壳70的外侧壁的挂环72。挂环72上设有耳部721。挂绳(图未示)可穿过耳部721的通孔7210,从而便于使用者通过挂绳将可吸入装置300悬挂于特定位置(如挂在脖子上,使得可吸入装置300便于携带)。
以下通过具体实施例和对比例对本申请作详细说明。其中,以可吸入装置为电子烟,且储液部件和导液部件分别为储油棉和导油棉为例对本申请进行说明。本领域技术人员应理解,本申请中描述的可吸入装置的具体类型以及储液部件和导液部件的具体材质仅是实例,其它任何合适的类型和材质均在本申请的范围内。例如,可吸入装置还可以是将液体雾化后输入人体的器械设备,如用于治疗上呼吸道疾病的医疗雾化吸入器。
实施例1
储液棉的外径为17mm,内径为5mm,高度为36.5mm。储液部件的孔隙率为4.5%。导液棉的密度为70g/cm
3。导液棉包括1层密度为70g/cm
3的竖纹亚麻棉和1层密度为70g/cm
3的横纹木浆棉(简称导液棉的结构组成为:1+1),亚麻棉最靠近发热器。
实施例2-3和对比例1-2
与实施例1不同之处在于横纹木浆棉的层数,具体参照表1。
对实施例1-3和对比例1-2的雾化器分别组装成电子烟样品,并对每一样品进行目标口数测试和最大口数测试,所采用的测试仪器为ZZ-DZ11电子烟抽烟机(执行UL8139标准要求,中洲测控(深圳)有限公司),测试指标为抽吸口数,执行口数标准为:仪器抽吸2秒、停20秒,记为1口。测试结果记录于表1中。其中,目标口数测试步骤为:假设电子烟的预设口数(即使用寿命)为500口,即使用者可以抽吸电子烟500次而不会出现干烧的现象;然后,将目标口数设定为500,然后采用上述仪器对样品开始测试;当仪器完成500口测试时,从仪器上取下样品,检查样品的外观以及雾化组件内部并确认样品是否 发生过干烧;当样品未发生干烧时为合格,反之为不合格。最大口数测试步骤与目标口数测试步骤基本相同,不同之处在于不需设置目标口数,而是直到样品发生干烧或者其它故障,导致不能继续完成抽吸操作为止才停止测试,此时记录得到的口数即为样品的最大口数。
表1
从表1结果可知,当储油棉的尺寸和孔隙率以及导油棉的密度满足特定条件时,设置导油棉中横纹木纹棉具有合适的层数,能够避免样品发生干烧。相较于实施例1-3,对比例1-2的横纹木纹棉的层数过多时,样品完成500口测试时容易发生干烧。其中,实施例3当横纹木纹棉的层数为3层时,样品具有最大口数。
实施例4-16和对比例3-4
与实施例1不同之处在于储油棉的孔隙率,具体参照表2。
表2
从表2结果可知,当储油棉的尺寸以及导油棉的密度和结构组成满足特定条件时,设置储油棉具有合适的孔隙率,能够避免样品发生干烧并使得样品具有较高的最大口数。相较于实施例1、4-16,对比例3的储油棉孔隙率过小,导致锁油速度大于输油速度,样品完成500口测试时容易发生干烧,而且对比例3吸阻过大,导致最大口数较小;对比例4的储油棉孔隙率过大,导致锁油速度小于输油速度,容易发生吸到烟油的现象,最大口数较小。其中,实施例1、5-10当储油棉孔隙率为4%~5%时,样品的最大口数较高。
实施例17和对比例5-8
与实施例1不同之处在于导油棉的密度,具体参照表3。
表3
样品序号 | 储油棉结构 | 导油棉密度 | 目标口数测试结果 | 最大口数测试结果 | 测试结论 |
对比例5 | 1+3 | 50 | 500口,没有干烧 | 532,有咕噜声 | 不合格 |
对比例6 | 1+3 | 55 | 500口,没有干烧 | 545,有轻微咕噜声 | 不合格 |

实施例18 | 1+3 | 65 | 500口,没有干烧 | 555 | 合格 |
实施例7 | 1+3 | 70 | 500口,没有干烧 | 565 | 合格 |
实施例19 | 1+3 | 75 | 500口,没有干烧 | 568 | 合格 |
实施例20 | 1+3 | 80 | 500口,没有干烧 | 564 | 合格 |

对比例7 | 1+3 | 90 | 500口,没有干烧 | 526,吸阻过大 | 不合格 |
对比例8 | 1+3 | 95 | 500口,发生干烧 | 488,吸阻过大 | 不合格 |
从表3结果可知,当储油棉的尺寸和孔隙率以及导油棉的结构组成满足特定条件时,设置导油棉具有合适的密度,能够避免样品发生干烧并使得样品具有较高的最大口数。相较于实施例1、4-16,对比例5-6的导油棉密度过小,导致锁油速度小于输油速度,样品抽吸时有咕噜声,最大口数较小;对比例7-8的储油棉密度过大,导致锁油速度大于输油速度,样品吸阻过大,最大口数较小。
以上仅为本申请的较佳实施例而已,并不用以限制本申请,凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等,均应包含在本申请的保护范围之内。
