具体实施方式
下面通过实施例的方式进一步说明本发明，但并不因此将本发明限制在的实施例范围之中。
请结合图1-图5予以理解，本实施案例提供一种过滤装置1，其包括：壳体10和加药件20。加药件20远离壳体10的一端设有胶塞21。
壳体10内设有未过滤腔11和已过滤腔12，未过滤腔11与已过滤腔12之间设有过滤膜13，壳体10上开设有进药口14和出药口15，且进药口14与未过滤腔11连通，出药口15与已过滤腔12连通；加药件20的一端与壳体10连接，且加药件20与未过滤腔11连通；其中，加药件20一体成型于壳体10。这样，通过将加药件20与过滤装置1结合，有效地减短了药液通过的管路的路径，减少了颗粒污染。
未过滤腔11包括相连通的第一容置腔111和第二容置腔112，进药口14与加药件20均与第一容置腔111连通，过滤膜13设于第二容置腔112与已过滤腔12之间。这样，通过设置第一容置腔111和第二容置腔112，使药液先通过第一容置腔111后再进入第二容置腔112，缓冲了药液对过滤膜13的冲击力。
第一容置腔111和第二容置腔112通过多个通孔16连通，且多个通孔16的轴线均与过滤膜13所在的平面平行。这样，通过设置通孔16连通的方 式，且通孔16的轴线均与过滤膜13所在的平面平行的设置，进一步缓冲了药液对过滤膜13的冲击力。在本实施例中，多个通孔16间隔等距设置。
第一容置腔111设置于已过滤腔12的一侧，第二容置腔112设置于已过滤腔12的上方。这样，通过对第一容置腔111、第二容置腔112以及已过滤腔12的相对位置设置，使过滤装置1的结构更为紧凑，大大地缩小了整体体积。
壳体10包括相对设置的上盖17和下壳18，过滤膜13夹设于上盖17与下壳18之间。上盖17开设有出气孔171，出气孔171对应于过滤膜13设置，且出气孔171与第二容置腔112连通，过滤装置1还包括防水膜172，防水膜172对应于出气孔171设置，且防水膜172设于第二容置腔112与出气孔171之间。这样，通过设置出气孔171，使药液通过过滤膜13时可能产生的气泡能够逸出。
在本实施例中，过滤装置1还包括支撑架19，支撑架19设于已过滤腔12内，支撑架19与下壳18连接，且过滤膜13抵靠于支撑架19远离下壳18的一端。这样，当药液集中于过滤膜13上方时，会对过滤膜13产生向下的作用力，通过设置支撑架19对过滤膜13起到抵御该作用力的作用，防止过滤膜13产生变形，并延长过滤膜13的使用寿命。
虽然以上描述了本发明的具体实施方式，但是本领域的技术人员应当理解，这些仅是举例说明，本发明的保护范围是由所附权利要求书限定的。本领域的技术人员在不背离本发明的原理和实质的前提下，可以对这些实施方式做出多种变更或修改，但这些变更和修改均落入本发明的保护范围。
