Description

Technical Field

[0001] This invention relates to the field of aquarium equipment technology, specifically to an aquarium that is easy to maintain in daily life. Background Technology

[0002] With the improvement of living standards, aquarium keeping has become a popular leisure and decoration method. While traditional aquariums (fish tanks) bring people enjoyment, their daily maintenance, such as water changes, cleaning the filtration system, testing and adjusting water quality, and controlling water temperature, is often tedious and requires certain professional knowledge. These tasks are not only time-consuming and energy-intensive, but improper operation can also cause drastic fluctuations in the aquatic environment, endangering the health of ornamental fish and even causing their death.

[0003] Existing aquariums suffer from cumbersome daily maintenance and insufficient precision in water quality control, failing to meet the demands for convenient and refined maintenance. On one hand, traditional aquariums rely heavily on manual cleaning of debris and water changes, which is not only time-consuming and labor-intensive but also prone to problems such as debris residue and uneven water exchange during water changes, easily disrupting the aquatic ecosystem balance. On the other hand, existing equipment lacks real-time and precise monitoring and control mechanisms for water quality parameters (such as turbidity and water composition) and water temperature. Water quality and temperature fluctuations are mainly judged by human experience, making it difficult to detect water quality deterioration or abnormal temperature in a timely manner. This can lead to unstable living environments for aquatic organisms, resulting in illness or even death.

[0004] Therefore, an aquarium that is easy to maintain in daily life is proposed to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide an aquarium that is easy to maintain in daily life, so as to solve the problems mentioned in the background art, such as the complex maintenance process, low control precision, high labor costs, easy ecological imbalance, lack of real-time monitoring and linkage control of water quality and temperature, and difficulty in ensuring the stability of the aquatic environment by relying on experience judgment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an aquarium that is easy to maintain daily, comprising a main tank body, wherein a breeding tank, a water storage tank, and a main controller are disposed within the main tank body; the water storage tank has a clear water chamber and a wastewater chamber that are separated from each other; and the bottom of the breeding tank body is connected to a filter and wastewater discharge chamber.

[0007] Preferably, the filter discharge chamber includes a bottom trough, and at least one sludge collection funnel is provided in the bottom trough, with a filter screen cover covering the top of the sludge collection funnel; The input end of the sewage pump is connected to a sludge collection box via a sewage pipe, the sludge collection box is connected to a sludge collection funnel via a sewage pipe, and the output end of the sewage pump is connected to a sewage chamber via a sewage pipe. The input end of the circulation pump is connected to the bottom of the filter and sewage discharge chamber, and the output end of the circulation pump is connected to the aquaculture tank after passing through the water quality monitoring module and the temperature control module in sequence via the circulation water pipe.

[0008] Preferably, the water quality monitoring module includes a turbidity meter, a water quality sensor, and a temperature sensor, which are sequentially arranged on the circulating water pipe along the water flow direction.

[0009] Preferably, a three-way solenoid valve is also provided on the circulating water pipe between the temperature sensor and the temperature control module. The three-way solenoid valve is electrically connected to the main controller and is used to switch the water circulation path.

[0010] Preferably, the circulating water pipe is connected to a guide channel at the outlet of the temperature control module, and the outlet of the guide channel faces the aquaculture tank. A pH sensor electrically connected to the main controller is installed inside the flow channel.

[0011] Preferably, a planting box is provided on the filter cover; The filter discharge chamber is equipped with aeration stones, which are connected to an air pump via air pipes. The air pump is electrically connected to the main controller.

[0012] Preferably, the top of both the clean water chamber and the wastewater chamber is provided with an openable and closable chamber cover, a duckbill valve, and an overflow prevention valve; A water level sensor, which is electrically connected to the main controller, is installed inside the water chamber.

[0013] Preferably, when the detection value of the turbidity meter or the water quality sensor exceeds a preset threshold, the main controller controls the start of the sewage pump to discharge the sewage in the filter sewage chamber into the sewage chamber, and after the sewage discharge is completed, controls the start of the water replenishment pump to replenish the clean water in the clean water chamber to the aquaculture tank.

[0014] Preferably, a self-locking push-button switch is provided on the sewage discharge pipeline between the sewage pump and the sewage chamber, and / or on the water supply pipeline between the water supply pump and the clean water chamber.

[0015] Preferably, the sewage pipe is equipped with a water shortage sensor and a full water sensor, and the water shortage sensor and the full water sensor are electrically connected to the main controller.

[0016] Preferably, the section of the sewage pipe located between the full water sensor and the sewage chamber has a U-shaped structure, and the U-shaped sewage pipe is equipped with an anti-siphon vent valve.

[0017] Preferably, the main body is equipped with an integrated control box located on top of the water storage tank, and the water quality monitoring module, temperature control module, water replenishment pump and air pump are all located inside the integrated control box; The water pump and air pump are externally covered with sound-absorbing covers; The integrated control box is rotatably connected to a tank cover on one side facing the aquaculture tank. The tank cover has a feeding port and a control panel that interacts with the main controller.

[0018] Compared with existing technologies, the beneficial effects of this invention are: this aquarium, which is easy to maintain daily, achieves autonomous maintenance and precise environmental control of the aquarium through an automated water circulation and water quality temperature linkage control system, effectively reducing labor costs and improving ecological stability. The specific details are as follows: Firstly, this invention automates and simplifies daily aquarium maintenance, effectively solving the problems of traditional aquariums relying on manual maintenance, which is cumbersome and costly. By setting up a water circulation loop consisting of a filter drain chamber, circulation pump, wastewater pump, water replenishment pump, and piping system, and with the main controller automatically controlling the start and stop of the wastewater and water replenishment pumps based on data from the water quality monitoring module, the water exchange between the aquarium and the wastewater / clean water chambers is completed. This eliminates the need for regular manual cleaning and water replacement, significantly saving labor and time costs. Simultaneously, the waste collection funnel and filter cover within the filter drain chamber work together to efficiently collect and initially filter waste, reducing residue. The interconnected design of the wastewater pump with the wastewater collection tank and wastewater chamber ensures thorough waste removal, and the water replenishment pump precisely replenishes clean water, avoiding the uneven water exchange problems that occur during manual water changes and effectively protecting the aquatic ecological balance within the aquarium.

[0019] Secondly, this invention establishes a precise water quality and temperature linkage control mechanism, overcoming the shortcomings of existing equipment's insufficient water quality control accuracy and reliance on manual experience to judge water temperature fluctuations. By setting up a water quality monitoring module and a temperature control module, including a turbidity meter, water quality sensor, and temperature sensor, in the water circulation loop, real-time and accurate monitoring of key parameters such as water turbidity, water composition, and temperature is achieved. The main controller is electrically connected to each monitoring module, temperature control module, and various pumps, enabling timely activation of corresponding control measures based on monitoring data. For example, it automatically discharges wastewater and replenishes water when water quality is abnormal, and adjusts the circulating water temperature through the temperature control module when temperature is abnormal. The three-way solenoid valve allows for flexible switching of the water circulation path, further improving control accuracy. Furthermore, the addition of components such as a pH sensor and a clear water level sensor further enhances the monitoring dimensions, ensuring the stability of the aquatic organisms' living environment and reducing their risk of disease or death.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-10 This invention provides a technical solution: an aquarium that is easy to maintain daily, mainly comprising a main tank 1, a breeding tank 2, a water storage tank 3, a filter and wastewater discharge chamber 6, an integrated control box 4, a main controller 20, and various pumps, sensors, pipelines, and other components. The main tank 1 is an integral load-bearing structure with rationally divided installation space inside, embedding the breeding tank 2, the water storage tank 3, and the filter and wastewater discharge chamber 6 respectively. The integrated control box 4 is fixedly installed on top of the water storage tank 3 within the main tank 1, and integrates core control components such as a water quality monitoring module, a temperature control module 13, a water replenishment pump 16, and an air pump 17. The main controller 20 uses an ESP32 series control board and is fixedly installed inside the integrated control box 4 to achieve centralized control of all actuators.

[0024] like Figure 6-7As shown, the water storage tank 3 is a one-piece molded structure made of acrylic material. Its interior is divided into an independent clear water chamber 301 and a wastewater chamber 302 by a sealed partition. The volume ratio of the two chambers is set to 1:1 to ensure sufficient clear water storage. Both the clear water chamber 301 and the wastewater chamber 302 are equipped with an openable and closable chamber cover 303, a duckbill valve 304, and an overflow prevention valve 305. The chamber cover 303 is made of transparent acrylic material and is threaded to the raised thread on the top of the water storage tank 3, facilitating the addition of clear water or the removal of wastewater. The duckbill valve 304 is a corrosion-resistant PVC duckbill valve (model: DN20 plastic duckbill valve), used to connect to the circulating water pipe 801 and the sewage pipe 701, respectively, to achieve one-way communication between the pipes and the chambers. The overflow prevention valve 305 is an acrylic overflow valve (model: Y416X-16PDN20), which automatically opens to prevent water overflow when the water level in the chamber exceeds the preset maximum value. In addition, a clean water level sensor 306 electrically connected to the main controller 20 is provided on one side of the bottom of the clean water chamber 301. The clean water level sensor 306 is a non-contact ultrasonic level sensor (model: JSN-SR04T waterproof ultrasonic level sensor), which is fixedly installed on the bottom inside the main body 1 to detect the clean water reserve in the clean water chamber 301 in real time.

[0025] like Figure 3-5 As shown, the filter and sewage discharge chamber 6 is fixedly installed inside the lower part of the main body 1 and is connected to the bottom of the aquaculture tank 2. It includes a bottom trough 601, which is integrally molded from acrylic material. Inside, there are six symmetrically distributed sewage collection funnels 602. The sewage collection funnels 602 have a conical structure and are made of food-grade PP plastic. Their tops are covered with filter screen covers 604, which are made of acrylic material (model: 304 stainless steel filter screen). They are used to perform preliminary filtration of the water discharged from the aquaculture tank 2 and intercept larger particulate impurities. The gap between the bottom tank 601 and the sludge collection funnel 602 can be used to place filter media (specifically, biological filter media such as quartz balls or ceramic rings can be selected). This idle space is used to further improve the water filtration effect. The filter media can adsorb fine impurities in the water and provide an attachment carrier for beneficial microorganisms such as nitrifying bacteria, thereby achieving biological purification. A planting box 603 can be detachably installed on the filter screen cover 604. The planting box 603 is made of hollow PP plastic box, and aquatic plants can be planted inside to achieve ecological purification. An aeration stone 18 is also set in the filtration discharge chamber 6. The aeration stone 18 is a nano bubble aeration stone (model: Φ50mm nano aeration stone). It is connected to an air pump 17 through an air pipe 1701. The air pump 17 is a silent oxygen pump (model: SUNSUNHAP-800 silent oxygen pump). The air pump 17 is electrically connected to the main controller 20. The main controller 20 can control the start and stop of the air pump 17 to realize the aeration and oxygenation of the water in the filtration discharge chamber 6.

[0026] like Figure 8As shown, the integrated control box 4 is made of acrylic material with a powder-coated surface, providing excellent dust and moisture resistance. Internally, it houses a water quality monitoring module, a temperature control module 13, a water replenishment pump 16, and an air pump 17. The water replenishment pump 16 and air pump 17 are externally covered by a sound-absorbing cover 15, which uses a sound-insulating cotton + ABS shell combination structure to effectively reduce noise generated during pump operation. The water replenishment pump 16 is a miniature DC submersible pump (model: DC12V miniature submersible pump silent self-priming pump) used to replenish the clean water in the clear water chamber 301 to the aquaculture tank 2. The temperature control module 13 uses a TEC device (model: TEC1-12706 semiconductor cooling chip) to regulate the temperature of the circulating water through semiconductor cooling / heating principles.

[0027] like Figure 1-2 As shown, the aquaculture tank 2 is made of ultra-clear glass, which has good light transmission and aesthetics. Its top is equipped with an openable tank cover 5, which is a combination of an aluminum alloy frame and a transparent acrylic panel, hinged to the top edge of the integrated control box 4. A feeding port 501 is provided on the tank cover 5. A control panel 502, which interacts with the main controller 20, is also located on the tank cover 5. The control panel 502 uses a button-type control panel and can display water quality parameters, water temperature, equipment operating status, and other information in real time. It also supports manual setting of parameter thresholds and control of equipment start / stop operations.

[0028] This invention connects the filter and sewage chamber 6, the aquaculture tank 2, the clear water chamber 301, and the sewage chamber 302 to the circulation pump 8, the sewage pump 7, and the water replenishment pump 16 via a pipeline system, forming a complete water circulation loop. All pipelines are made of food-grade PVC pipes, which have good corrosion resistance and safety. The specific connection relationships are as follows: The sewage pump 7 is a miniature self-priming sewage pump (model: WKY-15 miniature self-priming sewage pump). Its input end is connected to the sludge collection tank 702 through the sewage pipe 701. The sludge collection tank 702 is made of PP plastic and is fixedly installed inside the filter sewage chamber 6. It is connected to the bottom outlet of the six sludge collection funnels 602 through the sewage pipe 701 for temporary storage of the sludge collected by the sludge collection funnels 602. The output end of the sewage pump 7 is connected to the sewage chamber 302 through the sewage pipe 701, and the end of the sewage pipe 701 away from the sewage pump 7 is inserted into the duckbill valve 304 in the sewage chamber 302 to realize the connection between the sewage pipe 701 and the sewage chamber 302. In addition, a self-locking push-button switch 21 is installed on the sewage pipe between the sewage pump 7 and the sewage chamber 302. Pressing the self-locking push-button switch 21 determines whether the sewage pipe is connected: when the switch is pressed, it is in a locked conducting state, and the sewage pipe is connected; when the switch is pressed again, it is in a closed state, and the sewage pipe is disconnected. A water shortage sensor 703 and a full water sensor 704 are also installed on the sewage pipe 701. Both are non-contact capacitive level sensors (model: FDC2214 non-contact capacitive level sensor). The section of the sewage pipe 701 between the full water sensor 704 and the sewage chamber 302 has a U-shaped structure. This design ensures that the liquid level in the U-shaped pipe is consistent with the water level in the aquaculture tank 2. The full water sensor 704 is located at the highest liquid level in the U-shaped pipe, and the water shortage sensor 703 is located at the lowest liquid level in the U-shaped pipe, ensuring the accuracy of water level detection. Sensor 704 is electrically connected to the main controller 20 and is used to monitor the water level in the aquaculture tank 2 in real time. The water shortage sensor 703 can provide a feedback signal when the water level in the aquaculture tank 2 is lower than the preset lower limit to prevent the circulation pump 8 and the sewage pump 7 from running dry and being damaged. The full water sensor 704 can provide a feedback signal when the water level in the aquaculture tank 2 is higher than the preset upper limit to avoid excessive water replenishment and water overflow. An anti-siphon vent valve 705 (model: PVC anti-siphon vent valve DN20) is also installed on the sewage pipe 701 upstream of the full water sensor 704 to effectively prevent the water in the sewage chamber 302 from flowing back due to siphon effect.

[0029] The circulation pump 8 is a silent circulating water pump (model: SUNSUNCP-1000 silent circulating pump). Its input end is connected to the bottom of the filter and sewage discharge chamber 6 through a pipeline, and is used to draw water that has undergone preliminary filtration and aeration in the filter and sewage discharge chamber 6. The output end of the circulation pump 8 is connected to the aquaculture tank 2 through the circulating water pipe 801, which passes through the water quality monitoring module and the temperature control module 13 in sequence. The end of the circulating water pipe 801 away from the circulation pump 8 is inserted into the duckbill valve 304 in the clear water chamber 301 to realize the connection between the circulating water pipe 801 and the clear water chamber 301. A self-locking push switch 21 is correspondingly provided on the circulating water pipe 801. Pressing the switch can control the connection status between the circulating water pipe 801 and the clear water chamber 301. The circulating water pipe 801 is connected to the outlet end of the temperature control module 13 with a guide channel 14. The guide channel 14 is made of acrylic material and is fixedly installed on the top inner side of the aquaculture tank 2. Its outlet faces the inside of the aquaculture tank 2, so that the temperature-regulated water can flow evenly into the aquaculture tank 2. A pH sensor 19 (model: SEN0161 pH sensor) is installed in the guide channel 14 and is electrically connected to the main controller 20 to detect the pH value of the water flowing into the aquaculture tank 2 in real time.

[0030] The input end of the water replenishment pump 16 is connected to the clear water chamber 301 via a water replenishment pipe, and the output end is connected to the guide channel 14 via a water replenishment pipe. It is used to replenish the clear water in the clear water chamber 301 into the circulation pipeline, and then flow into the aquaculture tank 2. A self-locking push switch 21 is installed on the water replenishment pipeline between the water replenishment pump 16 and the clear water chamber 301. Pressing the switch can control the connection status of the water replenishment pipeline.

[0031] like Figure 9 As shown, the water quality monitoring module includes a turbidity meter 9, a water quality sensor 10, and a temperature sensor 11, which are sequentially installed along the water flow direction on the circulating water pipe 801. Each sensor is electrically connected to the main controller 20 and is used to collect various water quality parameters of the circulating water in real time and transmit them to the main controller 20. Turbidity meter 9: A portable turbidity sensor (model: WGZ-200B turbidity meter) is used to detect the turbidity of circulating water and determine the content of suspended particulate matter in the water. Water quality sensor 10: Employs a multi-parameter water quality sensor (model: Y500 multi-parameter water quality sensor), which can simultaneously detect multiple indicators such as ammonia nitrogen, nitrite, and nitrate in the water, comprehensively reflecting the water quality status; Temperature sensor 11: A waterproof temperature sensor (model: DS18B20 waterproof temperature sensor) is used to detect the temperature of the circulating water in real time, providing data for the adjustment of the temperature control module 13.

[0032] In addition, a three-way solenoid valve 12 (model: UD-16 three-way solenoid valve) is installed on the circulating water pipe 801 between the temperature sensor 11 and the temperature control module 13. The three-way solenoid valve 12 is electrically connected to the main controller 20 and is used to switch the water circulation path: when the water temperature needs to be adjusted, the main controller 20 controls the three-way solenoid valve 12 to switch to the path connected to the temperature control module 13. The water flows into the breeding tank 2 after the temperature is adjusted by the temperature control module 13. When the temperature adjustment is not required, the main controller 20 controls the three-way solenoid valve 12 to switch to the bypass path. The water flows directly into the breeding tank 2, bypassing the temperature control module 13, thus improving the water circulation efficiency.

[0033] Working principle: Before using this type of aquarium that is easy to maintain, it is necessary to check the overall condition of the device to ensure that it can function properly. Figure 1 - Figure 10 As shown, firstly, the main controller 20 controls the circulation pump 8 to start. The water in the aquaculture tank 2 flows into the filter drain chamber 6 through the bottom. After preliminary filtration by the filter screen cover 604, larger particles of impurities are intercepted on the filter screen cover 604, and some fine dirt settles into the sludge collection funnel 602 and flows into the sludge collection tank 702. After being aerated by the aeration stone 18 in the filter drain chamber 6, the filtered water is drawn into the circulation water pipe 801 by the circulation pump 8. The water passes through the turbidity meter 9, the water quality sensor 10, and the temperature sensor 11 in sequence. Each sensor collects water quality parameters and water temperature in real time and transmits them to the main controller 20. The main controller 20 controls the three-way solenoid valve 12 to switch paths based on the detection data of the temperature sensor 11. If the water temperature does not meet the preset threshold, the three-way solenoid valve 12 switches to the path connected to the temperature control module 13. After the water temperature is adjusted to the preset range by the TEC equipment, it flows into the guide channel 14 and finally flows back to the aquaculture tank 2, completing one normal water cycle.

[0034] The main controller 20 receives real-time detection data from the turbidity meter 9 and the water quality sensor 10, and compares it with preset thresholds (e.g., turbidity threshold 5 NTU, ammonia nitrogen threshold 0.5 mg / L). When the detection value of the turbidity meter 9 or the water quality sensor 10 exceeds the preset threshold, the main controller 20 determines that the water quality is abnormal and starts the water quality improvement program: First, it controls the circulation pump 8 to stop working, and at the same time controls the sewage pump 7 to start. The sludge stored in the sludge collection tank 702 and the sewage in the filter sewage discharge chamber 6 are discharged into the sewage chamber 302 through the sewage discharge pipe 701. At this time, the self-locking push switch 21 on the sewage discharge pipe is in the conducting state. During the sewage discharge process, the water shortage sensor 703 monitors the liquid level in the aquaculture tank 2 in real time. If the water level is detected to be lower than the preset lower limit (insufficient water), the sensor will detect the water shortage. If the water body is available for sewage discharge, the main controller 20 is notified to stop the sewage pump 7 from working to avoid dry running. The full water sensor 704 monitors the liquid level in the aquaculture tank 2 in real time. If the water level is detected to be higher than the preset upper limit during the water replenishment process, the main controller 20 is notified to stop water replenishment and issue an alarm signal. During the water replenishment process, the clear water level sensor 306 monitors the liquid level in the clear water chamber 301 in real time. If the liquid level is lower than the preset minimum value, the main controller 20 issues an alarm prompt through the control panel 502 to remind the user to replenish clear water and at the same time empty the sewage chamber 302. When the liquid level in the aquaculture tank 2 returns to the preset normal liquid level, the main controller 20 controls the water replenishment pump 16 to stop working and restarts the circulation pump 8 to restore normal water circulation.

[0035] The main controller 20 receives the detection data from the temperature sensor 11 in real time. When the detected water temperature is lower than the preset minimum threshold, the temperature control module 13 (TEC device) is controlled to be in heating mode to heat the circulating water until the water temperature reaches the preset range, and then the temperature control module 13 stops heating. When the detected water temperature is higher than the preset maximum threshold, the temperature control module 13 is controlled to be in cooling mode to cool the circulating water until the water temperature reaches the preset range, and then the temperature control module 13 stops cooling. Throughout the temperature regulation process, the three-way solenoid valve 12 is always in the path state connected to the temperature control module 13 to ensure that the water can be regulated and then flow back to the aquaculture tank 2.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
