This creation is a kind of related Combined biochemical ball of what, it is mainly that biochemistry ball ontology outer rim is convexly equipped at least one embedding tug protrusion for embedding tug combination fixation corresponding with the embedding tug groove of another biochemistry ball ontology, while what biochemistry ball ontology outer rim is recessed at least one embedding tug groove and combines fixation for the corresponding embedding tug in embedding tug protrusion of another biochemistry ball ontology, and then run through in what biochemistry ball ontology and offer number filtering slotThereby, the mutually embedding tug of energy between biochemistry ball ontology can be enabled to combine fixation, can effectively using limited filter space, it is neat in limited filtering environment put into most biochemistry ball ontologies, to reach more preferably filter efficacy, and integrally implemented at it and more increase practical effect characteristic person using upper.本創作係有關於一種組合式生化球,其主要係生化球本體外緣凸設有至少一嵌掣凸部供與另一生化球本體之嵌掣凹槽相對應嵌掣結合固定,同時於生化球本體外緣凹設有至少一嵌掣凹槽供又一生化球本體之嵌掣凸部相對應嵌掣結合固定,而於生化球本體內則貫穿開設有數過濾槽孔;藉此,能令生化球本體之間能相互嵌掣結合固定,可有效的利用有限的過濾空間、在有限的過濾環境中整齊的置放入最多的生化球本體,以達到更佳的過濾功效,而在其整體施行使用上更增實用功效特性者。(1)‧‧‧生化球本體(11)‧‧‧嵌掣凸部(12)‧‧‧嵌掣凹槽(13)‧‧‧過濾槽孔
