The utility model relates to a bottom suction device for an aquarium, which can be used for washing bottom sand, which comprises an air guide hose, a rough straw, a sewage suction pipe, a nozzle, a handle and a dirt collecting bag. The utility model relates to a sewage suction pipe, which is a pipe which is sheathed with two sleeves, and the length of the handle can be adjusted, and a handle is arranged above the handle. The lower part of the sewage suction pipe is connected with a section of thick straw, and the bottom of the suction pipe is provided with a nozzle with a transverse opening communicated with the oxygen injection pump through an air guiding hose. The utility model makes use of the air bubbles which are transversely ejected by the nozzle to cause the bottom sand to rotate in the rough straw, and the air bubbles are formed in the suction pipe to reduce the pressure. Because the crude Straw is larger than the diameter of the suction pipe, so the pumping power will be Straw crude is slightly less than the suction tube and the pumping force, the sediment into the crude Straw after not being sucked into the suction tube, the bottom of the aquarium can sand washing. And can absorb large amounts of dirt and rotten leaves, without clogging.
【技术实现步骤摘要】
本技术涉及一种能够吸取水族箱底部污物的装置,尤其是能够淘洗水族箱底沙的吸污装置。目前,观赏鱼饲养者在水族箱中一般都铺有底沙,以便在上面栽种水生植物。在长时间使用以后,底沙缝隙中会存留大量的污物。使用虹吸管吸取污物只能将底沙表面的污物吸出箱外,同时也会将大量的净水吸出。于是有人生产了一种吸头加粗,并且纵向开有进水口,手柄上安装一个离心水泵的底沙淘洗器。这种装置虽然可以不使底沙被吸出,但水泵容易被大块污物和腐烂的水草堵塞。上述两种方法对底沙缝隙中的污物均不能有效地吸除。本技术的目的是提供一种水族箱底部吸污装置,它不仅能够吸取水族箱底部的污物,而且能够吸取底沙缝隙中的大块污物和腐烂的水草叶。本技术的目的是这样实现的吸污管也用两根管子套接在一起,以便调整长度,在它的下方插接一段直径大于吸污管的粗吸管。吸污管的上方是手柄,它的一侧向下开有出污口,将可以存放污物的集污袋套在出污口上。注氧泵产生的压缩空气,被导气软管送到粗吸管底部的喷嘴喷出,在水中形成气泡后上升。吸污管内形成的与水族箱内同等深度水面的压强差,使污水流入粗吸管并在吸污管内上升,通过出污口最终进入到集污袋中。由于粗吸管直径大于吸污管,这样粗吸管内的抽力就会略小于吸污管内的抽力,使得底沙进入粗吸管后不会被吸入到吸污管中。为了使污水更容易进入粗吸管,它下面应纵向开有数个进水口。由于采用上述方案,底沙只能在粗吸管内翻动,其缝隙中的大块污物和腐烂的水草叶很容易被吸入到吸污管中,不会产生堵塞现象,从而可以实现对底沙的淘洗。以下结合附图和实施例对本技术进一步说明。附图说明图1是本技术的立体局剖图。图中1.吸污管 2.粗 ...
