Description

Technical Field

[0001] This utility model relates to the field of aquarium technology, specifically to an adjustable flow siphon pipe and aquarium. Background Technology

[0002] In existing technologies, aquarium siphon drainage systems typically use a fixed-diameter drain pipe structure, and the siphon drain pipe and safety overflow pipe are usually set up independently, which has the following drawbacks:

[0003] Unadjustable flow rate: Traditional siphon drain pipes have a fixed diameter and cannot automatically adjust the flow rate according to the pump's operating conditions (such as pressure fluctuations in a fixed-frequency pump) or changes in the aquarium's water level. This can easily lead to unstable or even interrupted siphon effect, affecting filtration efficiency.

[0004] Poor adaptability: Fixed-frequency water pumps operate with a constant output flow rate, but the actual water demand of the aquarium changes dynamically with factors such as water level and amount of debris. Existing siphon systems lack a flow regulation mechanism, making it difficult to match the characteristics of fixed-frequency water pumps. This often results in problems such as excessively rapid water flow dispersing debris or insufficient flow causing siphon failure.

[0005] Low space utilization: The separate design of the siphon drain pipe and the safety overflow pipe takes up extra space, which limits the installation layout of small fish tanks.

[0006] The aforementioned defects result in significant limitations in adapting existing siphon systems to fixed-frequency water pumps, necessitating a compact solution that can dynamically adjust flow rate and save space. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an adjustable flow siphon pipeline to solve the technical problem that the existing siphon drain pipes cannot be effectively adapted to fixed frequency water pumps due to their fixed pipe diameter.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0009] An adjustable flow siphon pipe includes: an inverted U-shaped pipe and a flow screw for adjusting the pipe diameter area of ​​the siphon drain; the flow screw is threadedly connected to the inverted U-shaped pipe, with one end located inside the inverted U-shaped pipe and the other end located outside the inverted U-shaped pipe.

[0010] Optionally, the flow screw is located at the top of the inverted U-shaped tube, and its end outside the inverted U-shaped tube has a Phillips head for easy flow adjustment by the user.

[0011] Optionally, a flow valve is provided on the inverted U-shaped pipe to adjust the pipe diameter area of ​​the siphon drainage.

[0012] Optionally, the flow valve is located at the upper end of the inverted U-shaped tube.

[0013] Optionally, the outlet end of the inverted U-shaped pipe is equipped with a T-connector, and the T-connector is equipped with a safety overflow pipe.

[0014] A fish tank comprising the aforementioned adjustable flow siphon line.

[0015] In summary, this utility model has the following beneficial effects: By combining the safety overflow pipe and the inverted U-shaped pipe in the design, this application effectively reduces the space occupied by the pipeline. At the same time, it innovatively adds an adjustable flow screw structure, which allows the inverted U-shaped pipe to flexibly adjust the drainage rate according to the constant flow characteristics of the fixed frequency water pump. This solves the problems of unstable siphoning, dirt impact, or insufficient drainage caused by water pump pressure fluctuations in traditional fixed diameter siphon pipes. While ensuring filtration efficiency, it achieves the dual goals of space optimization and improved adaptability. Attached Figure Description

[0018] To make the objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein.

[0019] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] This utility model provides an adjustable flow siphon pipeline, such as Figure 1-2As shown, it includes: an inverted U-shaped pipe 1, and a flow screw 11 for adjusting the pipe diameter area of ​​the siphon drain; the flow screw 11 is threadedly connected to the inverted U-shaped pipe 1, with one end located inside the inverted U-shaped pipe 1 and the other end located outside the inverted U-shaped pipe 1.

[0022] Specifically, the inverted U-shaped pipe 1 consists of two long vertical pipes and one short horizontal pipe. The short horizontal pipe is located between the two long vertical pipes and serves as a connection. One of the long vertical pipes is a water intake pipe, and the other is a water drain pipe. An air vent is provided at the bottom of the short horizontal pipe (not shown in the attached drawing, but refer to the air inlet 531 in patent CN220694158U). The entire inverted U-shaped pipe 1 is installed inside the breeding tank 5 via a water pipe connector and is located at the end corner. A water supply pipe 3 (connected to a fixed-frequency water pump) is also installed at this end corner. The water supply pipe 3 transports water from the bottom filter tank 4 to the breeding tank 5 from bottom to top through the fixed-frequency water pump. The inverted U-shaped pipe 1 uses a siphon effect to transport water from the breeding tank 5 back to the bottom filter tank 4. For ease of operation, the flow screw 11 is installed at the top of the inverted U-shaped tube 1. When the flow screw 11 is rotated clockwise, more of the flow screw 11 enters the interior of the inverted U-shaped tube 1, and the pipe diameter area of ​​the inverted U-shaped tube 1 for siphon drainage becomes smaller. When the flow screw 11 is rotated counterclockwise, more of the flow screw 11 enters the interior of the inverted U-shaped tube 1, and the pipe diameter area of ​​the inverted U-shaped tube 1 for siphon drainage becomes larger.

[0023] When the water is first changed, the water level in aquarium 5 is high, requiring rapid drainage to the normal level. This is achieved by rotating the flow screw 11 to increase the pipe diameter, thereby increasing the drainage flow and shortening the drainage time. Once the water level is normal, rotate the flow screw 11 to the standard position to maintain a constant flow rate matched to the fixed-frequency water pump, ensuring efficient filtration without disrupting the aquarium's ecosystem. If excessive water flow causes debris to spread from the bottom of aquarium 5, rotate the flow screw 11 to reduce the pipe diameter, decrease the flow rate, and slow the water flow to protect the fish and substrate. If siphon interruption occurs due to blockage by impurities or fluctuations in pump pressure, fine-tune the flow screw 11 to gradually increase the pipe diameter, restoring the siphon's negative pressure and re-establishing a stable water circulation. This application dynamically adjusts the pipe diameter and area of ​​the siphon's outlet via the flow screw 11, dynamically matching the pump output with the actual needs of the aquarium, solving the problems of siphon failure, energy waste, or ecological damage caused by the mismatch between the constant pump pressure and the variable aquarium conditions in traditional fixed-diameter siphon pipes.

[0024] In addition, if a fixed-frequency water pump is damaged and needs to be replaced, and the water output of the replacement fixed-frequency water pump is inconsistent with that of the original fixed-frequency water pump, flow compensation can be performed by rotating the flow screw 11 until a stable water flow circulation is established.

[0025] Furthermore, to facilitate flow adjustment by the user, the flow screw 11 is located at the top of the inverted U-shaped tube 1, and its end outside the inverted U-shaped tube 1 is provided with a Torx-shaped hand-tightening part (not shown in the attached figure). At this time, the flow screw 11 has a conventional Torx-shaped hand-tightening screw structure and is made of nylon.

[0026] Furthermore, to quickly adjust the pipe diameter and area of ​​the siphon drainage, a flow valve 12 is installed on the long vertical pipe of the inverted U-shaped pipe 1. The function of the flow valve 12 is similar to that of the flow screw 11, which is for coarse flow adjustment, while the flow screw 11 is for fine flow adjustment. The flow valve 12 can completely block the inverted U-shaped pipe 1, while the flow screw 11 can only block 0%-60% of the siphon drainage area of ​​the inverted U-shaped pipe 1. The flow valve 12 and the flow screw 11 are used together as needed to quickly and accurately adjust the siphon drainage flow rate, making the siphon drainage flow rate compatible with the fixed frequency water pump.

[0027] Furthermore, to facilitate user adjustment of the siphon drainage flow rate, the flow valve 12 is located at the upper end of the inverted U-shaped pipe 1, specifically at the upper end of the long vertical pipe.

[0028] Furthermore, the outlet end of the inverted U-shaped pipe 1 is equipped with a three-way connector 13, and a safety overflow pipe 2 is provided on the three-way connector 13.

[0029] like Figure 1-2 As shown, the outlet end of the inverted U-shaped pipe 1 is installed on the tee connector 13 via a 90-degree elbow. The upper end of the tee connector 13 is connected to the safety overflow pipe 2, and the lower end of the tee connector 13 is the siphon drain outlet, which is fixedly installed on the bottom plate of the aquaculture tank 5 using a water pipe connector. When the flow valve 12 is completely closed, the aquaculture tank 5 overflows water through the safety overflow pipe 2. At this time, the safety overflow pipe 3 is combined with the siphon drain pipe, reducing the space occupied by the drain pipe inside the aquaculture tank 5.

[0030] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
