Description

Technical Field

[0001] The invention relates to a fish tank external ecosystem cultivation barrel, in particular to a fish tank external ecosystem cultivation barrel composed of an external barrel body and a cleaning port. Background Art

[0002] People raise ornamental fish in fish tanks. In order to balance the ecosystem in the fish tank and purify and remove harmful substances such as ammonia, nitrite, and nitrate in the water, fish tank filter ecosystem cultivation containers have emerged. At present, there are three most common forms of fish tank filter ecosystem cultivation containers on the market: the first form is located above the fish tank, consisting of a filter container box and biochemical cotton in the filter container box. Since the biochemical cotton is not completely soaked in water, it is mainly used as a form of filtration, and its role as an ecosystem cultivation is relatively small, and this form is greatly affected by the desktop space. The second form is located below the fish tank, consisting of a bottom filter tank under the desktop and biochemical cotton in the bottom filter tank. This form requires a professional water discharge assembly and a float valve to control the water level in the bottom filter tank, or a solenoid valve to control the water level in the fish tank. It is expensive and complicated to operate. The third form is a finished product filter barrel outside the fish tank. The biochemical cotton in this form is completely soaked in water, but the volume of the finished barrel is small, and the effect of establishing a good ecosystem is minimal. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a fish tank external ecosystem culture barrel which has a large volume, is completely immersed in a biochemical blanket, is cheap and easy to operate.

[0004] In order to solve the above technical problems, the fish tank external ecosystem culture barrel of the present invention is composed of an external barrel body, an upper cleaning port, a lower cleaning port, a water inlet pipe, and a water outlet pagoda joint. There are sealed socket connections between the external barrel body and the upper cleaning port, and between the external barrel body and the lower cleaning port; there is a hole equal to the diameter of the connecting pipe on the upper side of the external barrel body, and there is a hole equal to the diameter of the connecting pipe on the lower side of the external barrel body; there is a three-way joint above the water inlet pipe, the middle of the three-way joint is connected to one end of the connecting pipe by a socket, the other end of the connecting pipe passes through the hole above the side of the external barrel body and is sealed with a pipe cap, the top of the three-way joint is connected to the lower end of the connecting pipe by a socket, and the upper end of the connecting pipe is connected to the flexible joint by a socket. , this flexible joint is sealed and connected to the pagoda joint; the lower part of the water inlet pipe is connected to the 90-degree elbow with a socket connection, the 90-degree elbow is connected to the connecting pipe with a socket connection, and the other end of the connecting pipe passes through the hole at the lower side of the external barrel body; there is a hole on the cap of the upper cleaning port with a size equal to the diameter of the connecting pipe, the lower end of the connecting pipe passes through the hole, the upper end of the connecting pipe is connected to the lower end of the flexible joint with a socket connection, the upper end of the flexible joint is connected to the lower end of the connecting pipe with a socket connection, the upper end of the connecting pipe is connected to the 45-degree elbow with a socket connection, and the 45-degree elbow is sealed and connected to the water outlet pagoda joint.

[0005] After adopting such a structure, since the water in the external barrel flows in from the bottom and out from the top, the air in the barrel is removed while the biochemical cotton is completely immersed in the water, thereby achieving the purpose of establishing a good ecological system. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0007] Figure 1 It is a schematic diagram of the three-dimensional structure of the culture barrel of the external ecosystem of the fish tank of the present invention;

[0008] Figure 2 It is a vertical view of the culture barrel of the external ecosystem of the fish tank of the present invention;

[0009] Figure 3 It is an exploded view of the culture barrel of the external ecosystem of the fish tank of the present invention;

[0010] Figure 4 It is a cross-sectional view of a culture barrel for an external ecosystem of a fish tank according to the present invention. DETAILED DESCRIPTION

[0011] like Figures 1 to 4 As shown, a fish tank external ecosystem culture barrel includes an external barrel body 1, an upper cleaning port 2, a lower cleaning port 3, a water inlet pipe 4, and a water outlet pagoda joint 5.

[0012] The water pump is placed in the fish tank, one end of a hose is connected to the water pump, and the other end crosses the fish tank and is connected to the pagoda connector 15 outside the fish tank as the water inlet of the ecosystem culture barrel, and the water outlet pagoda connector 5 is connected to another hose leading to the fish tank as the water outlet of the ecosystem culture barrel. When the water pump is started, the water level in the ecosystem culture barrel gradually rises from bottom to top, and the biochemical cotton in the barrel is immersed in the process of rising water level, and the air in the barrel is removed at the same time. When the water level rises to the top of the upper cleaning port, all the biochemical cotton in the barrel is completely immersed in water, and the air in the barrel is completely removed, and then the water flows back to the fish tank through the hose connected to the water outlet pagoda connector 5.

[0013] Through the above specific implementation methods, the fish tank external ecosystem culture barrel of the present invention can effectively solve the problems of small volume of fish tank filter ecosystem culture containers on the market, inability to fully immerse biochemical cotton, and difficulty in operation, and has the advantages of easy use and reliable performance.
