技术领域
本公开涉及食品保鲜技术领域，尤其涉及一种挥发装置和储物装置。
背景技术
冰箱使用一段时间后就会滋生细菌，进而产生异味。为了提高食用安全性和用户体验，一些冰箱内会安装杀菌盒，杀菌盒的盒盖开设有多个通气孔，杀菌盒内放置有由无纺布包裹着的缓释剂例如吸附型固态二氧化氯缓释剂。二氧化氯缓释剂通过通气孔吸收空气中的水分，进而产生二氧化氯气体，二氧化氯气体能杀死病毒、细菌、原生生物、藻类、真菌和各种孢子及孢子形成的菌体，并且还不与有机物发生氯代反应，不产生三致物质和其它有毒物质。
但是，二氧化氯缓释剂释放二氧化氯气体的速度与周围环境的温度和湿度有关：周围环境的温度或湿度越高，二氧化氯缓释剂吸收的水分就越多，进而释放二氧化氯气体的速度就越快。但是随着时间的推移，二氧化氯缓释剂释放二氧化氯气体的能力会逐渐减弱，直至完全失效。而由于周围环境的温度和湿度变化无常，因此二氧化氯缓释剂的使用寿命难以预估。此外，正常状态下二氧化氯气体的浓度并不高，用户很难通过闻气味来判断二氧化氯缓释剂是否已经失效，导致用户无法及时进行更换。

结合图1至图4所示，本实施例的挥发装置包括壳体100和变色件800，壳体100具有用于容纳待储物品的空腔，壳体100上形成有与空腔连通的出气口301；变色件800固定于壳体100，变色件800的一侧暴露于空腔，变色件800的另一侧可视于壳体100的外壁，也就是说，从壳体100的外侧可以看到变色件800；变色件800根据空腔中目标气体即待储物品释放的气体的浓度变色。其中，待储物品可以但不限于是固体杀菌剂或固体芳香剂。
下面以待储物品为二氧化氯缓释剂500、变色件800为明胶为例，对发明实施例中的挥发装置应用于冰箱时的工作原理进行说明：
明胶是胶原部分水解后的产物，属于一种大分子的亲水胶体。明胶为无色至浅黄色固体，且无嗅、无味、有光泽。明胶不溶于水，但浸泡在水中时，可吸收5～10倍的水而膨胀软化，明胶在吸收黄绿色到橙黄色的二氧化氯气体后，明胶的颜色也会变为黄绿色到橙黄色。
使用时，将放置有二氧化氯缓释剂500的壳体100放入冰箱，冰箱内的水汽就会通过出气口301进入空腔，存放在空腔内的二氧化氯缓释剂500吸收水汽后释放出二氧化氯气体。由于变色件800即明胶的一侧暴露于空腔中，因此明胶可与空腔内的二氧化氯气体直接接触，明胶吸附二氧化氯气体后其颜色由无色至浅黄色逐渐变为黄绿色到橙黄色。与此同时，空腔内的二氧化氯气体不断通过出气口301流入冰箱。随着时间的推移，二氧 化氯缓释剂500释放二氧化氯气体的能力逐渐减弱，在二氧化氯缓释剂500失效后，二氧化氯缓释剂500不再释放二氧化氯气体，之前明胶吸附的二氧化氯气体则被释放出来，明胶的颜色便从黄绿色到橙黄色重新变回浅黄色至无色。由于明胶的另一侧可视于壳体100的外壁，因此用户无需打开壳体100，直接从壳体100的外侧就可以观察到明胶颜色的变化。当用户观察到明胶的颜色为黄绿色到橙黄色，则说明此时二氧化氯缓释剂500仍然有效；当用户观察到明胶的颜色恢复到浅黄色至无色，则说明此时二氧化氯缓释剂500已经失效，由此用户就可及时更换二氧化氯缓释剂500或整个挥发装置。
为了实现变色件800一侧暴露于空腔，另一侧可视于壳体100的外壁，变色件800的安装位置和方式有多种，例如：
方式一、变色件800的一侧直接暴露于空腔中，具体地：如图3、图4、图6和图7所示，壳体100上开设有与空腔连通的观察窗口，变色件800嵌设于观察窗口中。在此方式下，变色件800的一侧暴露于空腔中，变色件800的另一侧暴露于外界环境中。为了避免变色件800被损坏，观察窗口中还嵌设有透明板700，透明板700扣设于变色件800背向空腔的一侧。当然，为了提高准确性，如图8和图9所示，观察窗口可设置多个。
方式二、变色件800的一侧间接暴露于空腔中，由于出气口301与空腔连通，因此变色件800可嵌设于出气口301中，且变色件800在出气口301上的投影面积小于出气口301的面积，也就是说，变色件800未完全堵住出气口301。例如，当出气口301呈矩形时，变色件800可为与出气口301等宽、且长度小于出气口301长度的矩形结构。又如，当出气口301呈圆形或椭圆形时，变色件800可为环形结构。
方式三、变色件800整体直接暴露于空腔中，具体地：壳体100由透明材质例如透明塑料制造而成，变色件800直接固定在壳体100的内壁上。
下面仍以待储物品为二氧化氯缓释剂500为例，考虑到冰箱内的温度相比外界环境的温度低很多，因此用户取、放食材的过程中外界温度较高的空气进入冰箱后就会凝结成水汽，致使二氧化氯缓释剂500吸收的水汽过多而持续不断地产生大量的二氧化氯气体，这不仅会导致二氧化氯缓释剂500的实际使用寿命大幅缩短，而且大量的二氧化氯气体也会影响用户体验，甚至还可能腐蚀冰箱内壁，因此为了减缓二氧化氯缓释剂500与外 界交换气体的速度，如图2所示，壳体100的空腔内设有第一环形筋310，第一环形筋310将空腔分隔为内外分布的容纳腔101和环形腔，容纳腔101位于环形腔的内侧；第一环形筋310开设有连通容纳腔101和环形腔的第一通气孔，第一通气孔与出气口301错开设置。由于壳体100的出气口301与第一环形筋310的第一通气孔错开设置，因此无论外界气体自出气口301流动至容纳腔101，还是容纳腔101内二氧化氯缓释剂500释放的二氧化氯气体自容纳腔101流动至出气口301，上述流动路径均非直线，气体需要多次改变流动方向，进而减缓了容纳腔101内二氧化氯缓释剂500与外界交换气体的速度，从而延长了二氧化氯缓释剂500的使用寿命。
由上可知，上述整个过程中二氧化氯气体都会路径容纳腔101、环形腔和出气口301，因此变色件800可暴露于容纳腔101、环形腔和出气口301中的任意一处。
进一步地，如图2、图11和图12所示，为了减小气体在环形腔内的流动速度，环形腔内设有隔板320，隔板320将环形腔分隔为前后分布的两个缓冲腔；隔板320开设有连通两个缓冲腔的第二通气孔321；容纳腔101通过第一通气孔与其中一个缓冲腔连通，另外一个缓冲腔与出气口301连通。
为了便于描述，下面将图2中位于前侧的缓冲腔称为第一缓冲腔102，将位于后侧的缓冲腔称为第二缓冲腔103，假设容纳腔101通过第一通气孔与第一缓冲腔102连通、第二缓冲腔103与出气口301连通，那么在壳体100放入冰箱后，冰箱内的水汽就会通过出气口301进入第二缓冲腔103。由于第二缓冲腔103通过第二通气孔321与第一缓冲腔102连通，因此进入第二缓冲腔103的水汽又会通过第二通气孔321由后至前流入第一缓冲腔102，进而再通过第一通气孔进入容纳腔101。而容纳腔101内的二氧化氯缓释剂500吸收进入容纳腔101的水汽后就会产生二氧化氯气体，从而当容纳腔101内的二氧化氯气体达到一定量以后，二氧化氯气体又会通过第一通气孔进进入第一缓冲腔102，第一缓冲腔102内的二氧化氯气体积累到一定量以后又会通过第二通气孔321由前至后流入第二缓冲腔103，并最终通过出气口301排出壳体100、释放到冰箱中。可见，无论是冰箱内的水汽自出气口301流动至容纳腔101，还是二氧化氯缓释剂500产生的二氧化氯气体自容纳腔101流动至出气口301，两个流动路径都是 非直线，气体需要多次改变流动方向。并且，受到隔板320的阻挡，气体在第一缓冲腔102与第二缓冲腔103之间流动速度显著降低。
需要说明的是，容纳腔101除了可以通过第一通气孔直接与第一缓冲腔102连通以外，还可以通过第一通气孔直接与第二缓冲腔103连通，在此情况下出气口301与第一缓冲腔102连通。由此，外界气体通过出气口301进入第一缓冲腔102，蓄积在第一缓冲腔102内的外界气体又会通过第二通气孔321由前至后流入第二缓冲腔103，进而再通过第一通气孔进入容纳腔101。由于容纳腔101内待储物品产生的气体自容纳腔101流动至出气口301的路径正好相反，因此此处不再赘述。
如图4和图5所示，第一通气孔为形成于第一环形筋310的第一侧边沿的缺口311，出气口301临近第一环形筋310的第二侧边沿设置，第一环形筋310的第一侧边沿和第二侧边沿相对设置。这样设置的好处在于，可使缺口311和出气口301之间的前后距离达到最大，进而延长气体在两个缓冲腔内的流动时间。此外，为了进一步减缓气体通过缺口311的速度，壳体100朝向缺口311的内壁形成有与缺口311相对设置的挡板210，挡板210位于容纳腔101内；挡板210的自由端朝第一环形筋310的第二侧边沿延伸，挡板210的延伸长度不小于缺口311的高度，挡板210朝向第一环形筋310的侧壁与第一环形筋310之间具有间隙211。
下面仍以二氧化氯缓释剂500为例，现将图2中位于前侧的缓冲腔称为第一缓冲腔102，将位于后侧的缓冲腔称为第二缓冲腔103，缺口311形成于第一环形筋310的前侧边沿，第一缓冲腔102与容纳腔101通过缺口311连通；挡板210的一端固定于壳体100的前表面，挡板210的另一端向后延伸；出气口301形成于壳体100的外壁并临近第二环形筋220的后侧边缘。受到挡板210的阻挡，二氧化氯缓释剂500在容纳腔101内产生的二氧化氯气体达到一定量以后，二氧化氯气体必须先绕过挡板210，并通过挡板210与第一环形筋310之间的间隙211才能到达缺口311，进而再流入第一缓冲腔102。当第一缓冲腔102内的二氧化氯气体积累到一定量以后又会通过第二通气孔321由前至后流入第二缓冲腔103，并最终通过出气口301排出壳体100。外界环境中的气体自出气口301流至容纳腔101的路径与上述方向正好相反，此处不再赘述。可见，无论是外界环境中的气体自出气口301流动至容纳腔101，还是容纳腔101内待储物品 产生的气体流动至出气口301，气体都需要至少绕过两个弯道，气体需要多次改变流动方向，进而显著减缓了容纳腔101内待储物品与外界交换气体的速度，从而延长了待储物品的使用寿命。
此外，如图4和图7所示，第一环形筋310的第一侧边沿可开设多个缺口311，在此情况下为了便于加工，挡板210可采用环形板。另外，为了避免挡板210影响待储物品在容纳腔101内的存放，挡板210的延伸长度等于或略大于缺口311的高度。为了更好的控制气体流动速度，如图5所示，缺口311的高度h可以但不限于是0.3mm～1.5mm，间隙211的宽度d可以但不限于是0.3mm～1mm。
另外，考虑到壳体100一般竖向安装，以冰箱为例，如图14所示，壳体100通常固定在冰箱抽屉410的侧壁，所以，为了防止食材上凝结的水珠直接落入壳体100的出气口301，以图3中的方位为基准，出气口301可设置在壳体100的左侧壁、右侧壁和/或底面，也就是说，除了壳体100的顶面以外，出气口301可以设置在壳体100其他任意位置。
如图6所示，壳体100包括前盖200和后盖300，后盖300的一侧为敞口，前盖200可拆卸地盖设于敞口，前盖200与后盖300围设形成空腔；第一环形筋310的一侧边沿固定于后盖300，第一环形筋310的另一侧边沿延伸至前盖200。由此，如图2所示，将前盖200盖设在后盖300的敞口以后，后盖300敞口的端面以及第一环形筋310延伸至前盖200的端面均紧贴前盖200的内壁。由此，前盖200和后盖300之间就可形成两道密封，从而便可避免外界气体通过前盖200和后盖300之间缝隙进入容纳腔101内。如图6所示，在环形腔内设有隔板320的情况下，第一环形筋310和隔板320可与后盖300一体成型。当然，为了便于隔板320成型，后盖300上敞口的相对侧开设有与隔板320相对设置的环形开口，也就是说，图2中第二缓冲腔103背向第一缓冲腔102的一侧为敞口。
需要说明的是，实现前盖200与后盖300可拆卸连接的方式有多种，例如：
方式一、卡接。如图3、图7和图13所示，环形腔的侧壁形成有多个楔形凸起330，前盖200朝向后盖300的一侧形成有与楔形凸起330一一对应的第一卡钩230，第一卡钩230与对应的楔形凸起330卡接。如图3所示，第一卡钩230包括支撑臂和钩部，支撑臂的一端固定于前盖200， 支撑臂的另一端侧壁形成有钩部。其中，支撑臂与钩部可一体成型。如图10所示，为了保证第一卡钩230与楔形凸起330的顺畅卡合，钩部突出于支撑臂的高度D范围可为0.5mm～1mm。另外，如图3和图8所示，在环形腔内设有隔板320的情况下，为了保证第一卡钩230与楔形凸起330有足够的卡合空间，楔形凸起330可设置在远离前盖200的缓冲腔的侧壁，此时隔板320上开设有与楔形凸起330对应的第一卡接孔322。使用该挥发装置时，首先将待储物品例如二氧化氯缓释剂500放入容纳腔101；然后将前盖200设有第一卡钩230的一侧朝向后盖300的敞口，并使第一卡钩230穿过第一卡接孔322伸入设有楔形凸起330的缓冲腔内即第二缓冲腔103中；最后，只需朝后按压前盖200即可，在该按压力的驱动下，第一卡钩230的钩部沿着对应楔形凸起330的楔形面滑动至楔形凸起330的后方并勾住楔形凸起330，由此便可将前盖200固定在后盖300的敞口。
同理，为了便于该挥发装置的固定，如图7所示，后盖300背向前盖200的一侧形成有多个第二卡钩340。以冰箱抽屉410为例，如图6所示，冰箱抽屉410的侧壁可预先注塑成型与第二卡钩340一一对应的第二卡接孔401，第二卡接孔401的侧壁也可设置用于与第二卡钩340卡接配合的楔形凸起。
方式二、磁性吸合。如图10所示，前盖200设有第一磁性件610，后盖300设有与第一磁性件610吸合的第二磁性件620。需要说明的是，前盖200朝向后盖300的一侧可设置多个第一磁性件610，在此情况下环形腔内设有与第一磁性件610一一对应的第二磁性件620。为了保证前盖200和后盖300之间的密封性，第一磁性件610的数量至少为四个，其中四个第一磁性件610分布于前盖200的四角，第二磁性件620分布在环形腔的四角。其中，第一磁性件610可以但不限于是铁片，第二磁性件620可以但不限于是磁铁。需要说明的是，第一磁性件610和第二磁性件620的位置不受附图限制，并且此处所述的第一磁性件610和第二磁性件620为能够对磁场作出反应的部件，也就是说，能够被磁场吸引或排斥的部件，例如磁铁或由磁性材料制成的部件。
同理，为了便于该挥发装置的固定，也可在后盖300背向前盖200的一侧固定第三磁性件，在冰箱抽屉410的侧壁固定第四磁性件，第三磁性件用于与第四磁性件吸合。
当然，对于方式一和方式二来说，如图1和图7所示，为了便于将前盖200从后盖300上取下，前盖200的边沿形成有施力部260，施力部260探出后盖300。当需要取下前盖200时，用户只需扣住施力部260向后即远离后盖300的方向扳动前盖200即可。其中，施力部260可设置在前盖的一侧边沿，以便于用户单侧集中施力。如图1所示，施力部260探出后盖的高度H不小于1mm，施力部260的宽度W不小于10mm。
方式三、螺纹连接。具体地，前盖200的边沿向后弯折以形成翻边，翻边的内壁开设有内螺纹，后盖300的外壁开设有与内螺纹螺纹配合的外螺纹。由此，安装前盖200时只需将前盖200扣在后盖300的敞口后，拧动前盖200即可。
方式四：螺钉连接。具体地，后盖300的敞口端面开设有多个螺纹孔，前盖200上开设有与螺纹孔一一对应的通孔。安装前盖200时，先将前盖200扣在后盖300上，并使前盖200的通孔对准对应的螺纹孔；然后将螺钉穿过通孔后拧入对应的螺纹孔即可。
此外，如图2所示，为了进一步阻隔外界气体通过前盖200与后盖300之间的缝隙进入容纳腔101，前盖200朝向后盖300的一侧形成有第二环形筋220，第二环形筋220伸入环形腔中，且第二环形筋220紧贴后盖300的侧壁。由此，即使外界气体流入前盖200与后盖300端面之间的缝隙，但是由于第二环形筋220紧贴后盖300的侧壁，因此受到第二环形筋220的阻挡，这些外界气体也无法进入环形腔，从而更无法进入容纳腔101。
如图8所示，出气口301形成于后盖300的侧壁，出气口301位于后盖300远离前盖200的边沿，以避免放入冰箱的食材遮挡出气口301；变色件800可固定于前盖200和/或出气口301。如图6至图8所示，后盖300的左侧壁、右侧壁和底面均开设有出气口301。这样设置的好处在于，不仅可以防止食材上的凝结的水珠直接落入出气口301，而且还能满足容纳腔101内待储物品与外界交换气体。
此外，如图7和图13所示，为了便于更换和固定待储物品，前盖200朝向后盖300的一侧形成有多个卡扣240，多个卡扣240之间形成待储物品的放置空间；卡扣240的自由端朝向前盖200的中心弯折，以夹持待储物品。当需要更换待储物品例如二氧化氯缓释剂500时，用户可先将前盖200从后盖300上拆下，然后将之前固定在多个卡扣240之间的二氧化氯 缓释剂500取下，然后将新的二氧化氯缓释剂500放置在多个卡扣240之间，并使新的二氧化氯缓释剂500的边缘被夹持在卡扣240自由端下，最后将前盖200和待储物品一起安装在后盖300上即可。整个更换过程中，用户只需取下前盖200即可，无需将整个挥发装置拆下。
如图13所示，为了便于待储物品安装定位，前盖200朝向后盖300的一侧形成有第三环形筋250，多个卡扣240固定于第三环形筋250，并沿第三环形筋250的周向间隔设置。此外，为了提高卡扣240对待储物品施加的夹持力，卡扣240的固定端与第三环形筋250可通过转轴转动连接，转轴上套设有扭簧。由此，当需要放置待储物品时，用户可先扳起卡扣240，即将卡扣240朝远离前盖200内壁的方向转动；然后再将待储物品放置在第三环形筋250围设的区域内；最后松开卡扣240即可，此时卡扣240在扭簧的驱动下朝趋近前盖200内壁的方向转动，直至压紧待储物品。其中，第三环形筋250和挡板210可为同一部件。
另外，本实用新型实施例还提供了一种储物装置，该储物装置包括箱体400和上述挥发装置，壳体100固定于箱体400内。其中，箱体400可以但不限于是冰箱、零售柜、展示柜或衣柜。例如，箱体400为冰箱时，壳体100既可以固定于冰箱的箱胆内壁或门体内壁上，也可以固定于冰箱的瓶框或抽屉410侧壁上。
本实施例中的储物装置通过采用上述挥发装置，不仅可以满足箱体400内的杀菌、除臭等需求，而且用户通过观察变色件800的颜色变化就可直观判断出待储物品的有效性，方便用户及时更换。
以上实施方式仅用于说明本公开实施例，而非对本公开实施例的限制。尽管参照实施例对本公开实施例进行了详细说明，本领域的普通技术人员应当理解，对本公开实施例的技术方案进行各种组合、修改或者等同替换，都不脱离本公开实施例技术方案的精神和范围，均应涵盖在本公开的权利要求范围当中。
