Description

Technical Field

[0001] This utility model relates to the field of aquarium technology, and in particular to a water inlet and outlet protection system for aquariums. Background Technology

[0002] Traditional pipeless aquarium circulation systems typically use a water pump to deliver water from the storage tank to the aquarium via a water inlet pipe. Gravity then causes the water in the aquarium to flow back to the storage tank via a drain pipe, creating a closed loop. To prevent overflow, a ball valve is installed at the drain outlet. When the water level in the storage tank exceeds a preset level, the drain pipe is shut off to prevent overflow.

[0003] In actual use, ball valves may become damaged or malfunction after prolonged use, leading to overflow.

[0004] Therefore, improvements are needed. Utility Model Content

[0005] The technical problem solved by this utility model is to address the deficiencies in the prior art by providing a water inlet and outlet protection system for a fish tank, thereby resolving the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A water inlet and outlet protection system for a fish tank, comprising: a fish tank and a water storage tank; the fish tank is provided with a water inlet pipe for water inlet, and a water outlet pipe for water outlet; a water pump is provided in the water storage tank, the water pump is connected to the water inlet pipe, the water outlet pipe extends to the water storage tank, and a ball valve is provided at the outlet of the water storage tank on the water outlet pipe, comprising: a water inlet solenoid valve, the water inlet solenoid valve is provided in the water inlet pipe, the water inlet solenoid valve is used to open or close the water inlet pipe; a water outlet solenoid valve, the water outlet solenoid valve is provided in the water outlet pipe, the water outlet solenoid valve is used to open or close the water outlet pipe; a liquid level sensor, the liquid level sensor is provided in the water storage tank, the liquid level sensor is used to detect the liquid level in the water storage tank, and feeds back the detection signal to the water outlet solenoid valve; a control circuit board, the control circuit board is electrically connected to the water inlet solenoid valve, the water outlet solenoid valve and the liquid level sensor, the control circuit board is used to receive signals and output signals.

[0007] Furthermore, it includes a power strip, which is electrically connected to the control circuit board and is used to electrically connect to the water pump. The power strip is provided with a delay circuit.

[0008] Furthermore, it includes a power cord electrically connected to the control circuit board, the power cord being used for electrical connection to mains power.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Dual overflow protection: A liquid level sensor monitors the water level in the storage tank in real time. Combined with the rapid opening and closing function of the drain solenoid valve, it can immediately shut off the drain pipe to prevent overflow in case of ball valve failure or abnormal water level. The inlet solenoid valve can simultaneously control the opening and closing of the inlet pipe, preventing the water level in the aquarium from becoming too high due to continuous pumping, forming a double safety mechanism. Simultaneously, the ball valve can still close the drain pipe even when power is off, preventing overflow.

[0011] Intelligent linkage control: The control circuit board integrates the coordinated control of liquid level sensors, solenoid valves, and water pumps to achieve automated management and reduce manual intervention. When an abnormal water level is detected (such as water level in the storage tank being too high or too low), the system can automatically shut off the solenoid valve or stop the water pump to prevent equipment damage.

[0012] Integrated design: The water pump's power strip is centrally located on the control circuit board, making it more convenient to use and easier to manage. Attached Figure Description

Furthermore, 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. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "several" or "more than" means two or more, unless otherwise explicitly specified. In this application, unless otherwise expressly 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 application according to the specific circumstances. In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or it can include contact between the first and second features through another feature between them. Moreover, "above," "over," and "on top" of a second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" of a second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0018] In view of the technical problems described in the background art, as shown in the figure, a water supply and drainage protection system for a fish tank 1 is provided, including: a fish tank 1 and a water storage tank 2; the fish tank 1 is provided with a water inlet pipe 3 for water inlet, and a water outlet pipe 4 for water outlet; a water pump 5 is provided inside the water storage tank 2, the water pump 5 is connected to the water inlet pipe 3, the water outlet pipe 4 extends to the water storage tank 2, and a ball valve 6 is provided at the outlet of the water storage tank 2 on the water outlet pipe 4, including: a water inlet solenoid valve 7, the water inlet solenoid valve 7 is provided on the water inlet pipe 3, and the water inlet solenoid valve 7 is used to open or close the water supply and drainage system. The system includes: a water inlet pipe 3 (closed); a drain solenoid valve 8 (installed in the drain pipe 4, used to open or close the drain pipe 4); a level sensor 9 (installed in the water storage tank 2, used to detect the level of water in the tank 2 and feed the detection signal back to the drain solenoid valve 8); and a control circuit board 10 (electrically connected to the water inlet solenoid valve 7, the drain solenoid valve 8, and the level sensor 9, used to receive and output signals).

[0019] According to the description in the background art, in a traditional pipeless aquarium 1, a ball valve 6 is installed at the outlet of the drain pipe 4. The ball valve 6 is used to close the drain pipe 4 based on the water level in the water storage tank 2, thereby preventing overflow. However, when the ball valve 6 malfunctions or is damaged, it cannot close the drain pipe 4, resulting in overflow.

[0020] To address this technical issue, a water supply and drainage protection system for a fish tank 1 is provided. This system primarily involves adding a drain solenoid valve 8 and a level sensor 9 to a traditional pipeless fish tank 1. The level sensor 9 is installed on the water storage tank 2 at a safe water level. Water enters the water storage tank 2 through the drain pipe 4. When the water level exceeds the safe level, the level sensor 9 transmits a signal to the control circuit board 10. The control circuit board 10 then drives the drain solenoid valve 8 to close the drain pipe 4 and simultaneously shuts off the water pump 5.

[0021] In the event of a power outage, water enters the water storage tank 2 through the drain pipe 4. When the water level exceeds the safe water level, the ball valve 6 closes the drain pipe 4 to prevent continuous water flow and overflow.

[0022] In the above technical solution, the water level in the storage tank is monitored in real time by the liquid level sensor 9. Combined with the rapid opening and closing function of the drain solenoid valve 8, the drain pipe can be immediately shut off to prevent overflow when the ball valve 6 fails or the water level is abnormal. The water inlet solenoid valve 7 can simultaneously control the opening and closing of the water inlet pipe 3 to prevent the water level in the aquarium from becoming too high due to continuous pumping, forming a double insurance mechanism. At the same time, the ball valve 6 can still close the drain pipe 4 even when the power is off to prevent overflow.

[0023] Intelligent linkage control: The control circuit board integrates the coordinated control of liquid level sensors, solenoid valves, and water pumps to achieve automated management and reduce manual intervention. When an abnormal water level is detected (such as water level in the storage tank being too high or too low), the system can automatically shut off the solenoid valve or stop the water pump to prevent equipment damage.

[0024] This utility model includes a power strip 11, which is electrically connected to the control circuit board 10 and is used to electrically connect to the water pump 5.

[0025] Preferably, since the water pump 5 requires an additional connection socket, the connection is inconvenient. To address this, a power strip 11 is additionally provided on the control circuit board 10 for connecting the water pump 5. The power strip 11 is equipped with a delay circuit. This makes it more convenient to use and easier to manage. When power is restored, the delay circuit on the power strip ensures that the water pump 5 operates smoothly only when the water inlet solenoid valve is fully open.

[0026] This utility model includes a power cord 12, which is electrically connected to the control circuit board 10 and is used for electrical connection with mains power.

[0027] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
