Embodiment 1

[0016] Embodiment 1: refer to Figure 1 to Figure 2 , a flexible air stone, wherein: it has a main frame 1; the main frame 1 is covered with an air bubble generating piece 3 fixed by a snap ring 2 along the mouth; the air bubble generating piece 3 is made of a flexible material and has a through-hole structure; Parts can inflate the inner cavity of the main frame 1.

[0017] The material of air bubble generating sheet 3 is cotton cloth or chemical fiber cloth.

[0018] The main frame 1 is a disc structure with an opening on one side; two fixed convex rings 12 are formed on the outer circumference of the main frame 1; 21; The air bubble generating sheet 3 can just be clamped between the fixed convex ring 12 and the fixed concave ring 21 .

[0019] The intake part is an intake pipe 11; the side peripheral surface near the free end of the intake pipe 11 is formed with 2 protruding anti-slip lines 11a.

Embodiment 2

[0020] Embodiment 2: refer to Figure 3 to Figure 4 , a flexible air stone, wherein: it has a main frame 1; the main frame 1 is covered with an air bubble generating piece 3 fixed by a snap ring 2 along the mouth; the air bubble generating piece 3 is made of a flexible material and has a through-hole structure; Parts can inflate the inner cavity of the main frame 1.

[0021] The material of air bubble generating sheet 3 is cotton cloth or chemical fiber cloth.

[0022] The main frame 1 is a ring structure with openings on both sides; the two edges of the main frame 1 are respectively provided with snap rings 2;

[0023] The air intake component is an air intake pipe 11; the side peripheral surface near the free end of the air intake pipe 11 is formed with two protruding anti-slip lines 11a.

Abstract

The invention discloses a flexible air stone. The flexible air stone is characterized in that the flexible air stone is provided with a main frame; bubble generating pieces fixed by clamp rings cover the edge openings of the main frame; the bubble generating pieces are made of flexible materials and are offset with through hole structures; and the main frame is provided with an air suction component which can aerate the inner cavity of the main frame. By adopting the above structure, the working surfaces of the generated bubbles are larger and are beneficial to aeration of the water body, and the structure is simple and convenient to dismantle and clean. Therefore, the flexible air stone has a softer surface, ensures the generated bubbles to be fine and uniform and have a large area, is convenient to clean and dismantle and has a good aeration effect.

Description

technical field [0001] The invention relates to an inflatable device for aquaculture, in particular to a flexible air stone. Background technique [0002] Today, in order to improve living standards and productivity, people often use aquariums to breed various fish, and in the process of raising seedlings, they also encounter the operation of temporarily raising and hatching eggs in small water bodies. Therefore, sufficient oxygen is needed in aquaculture water, and air stones come into being; at present, the air stones used by people are generally non-sintered air stones. Stones are poor in acid and alkali resistance. Generally, they can only be used for about a year before they become loose due to the aging of the binder. Moreover, the bubbles produced by this type of air stone are large, and the efficiency of inflating air is relatively poor; there are also some air stones on the market. It is also made of quartz sand as the skeleton, Arabic resin, etc. as the binder, an...
