われた。(Prior art) This type of filter uses a flow of fine bubbles ejected from a foam and a water flow caused by the flow.
It has a structure that sucks water from outside the filter into the filter and filters it, and releases air bubbles and filtered water from an outlet formed integrally with the filter. However, if the discharge port is too short relative to the water depth, it will not reach the inside of the tank, so a pipe was installed to promote circulation as disclosed in Japanese Utility Model Publication No. 5242/1983.

お蛇腹部は消音的作用も行なう。(Function of the device) The device of the present invention has a sloped wall 7 with a gentle slope and a sloped wall 8 with a steeper slope as a nozzle provided at the outlet of the filter.
Because it has a bellows part that is alternately combined, it can be used by changing the length of expansion and contraction and being fixed at a height depending on the size of the aquarium and the depth of the water, and at the same time, the direction and angle of inclination can be changed and fixed respectively. The final outlet can be set at any position in the aquarium. Since the nozzle position and direction can be freely set, the foaming air flow and filtered water flow are stabilized and the filter function is fully demonstrated regardless of the size and shape of the aquarium. The bellows also has a sound-deadening effect.

設けるよりもしつかりした構造となる。 The bellows parts 2 and 3 consist of a series of triangular wave-shaped sloped walls, including a sloped wall 7 with a gentle slope and a sloped wall 8 with a steeper slope.
A set of these is formed in large numbers in succession, and as a result, it not only has elasticity and flexibility, but also allows it to be fixed at any length when expanded or contracted, and the direction can be changed freely. In addition, even when bent, it is fixed at that angle of inclination, and at the same time the rigidity is increased (first
(See Figure 2). Since multiple bellows parts are provided,
The degree of freedom in expansion, contraction and flexibility is increased, and the structure is more durable than if it were provided in one location for a long time.

よる消音効果も期待できる。(Effects of the invention) Since the invention is constructed and operates as described above, the foamed air flow generated within the filter and replenishing oxygen into the water can be released to any position regardless of the size or shape of the aquarium. The water flow generated along with this also forms a constant and stable flow within the nozzle member, thus promoting the water flow suction action accompanying the air flow, and the effect of fully bringing out the function of the filter. There is. In particular, it is possible to set the ejection position of the foaming air flow and the formation part of the filtered water flow at positions suitable for the conditions such as the size and form of the aquarium only by using the bellows parts 2 and 3; It does not require any tools, is independent, has a high degree of freedom in positioning, and does not take up much space. Additionally, the bellows section can also be expected to have a noise-reducing effect.
