Therefore, from the above, it can be seen that this invention has the following advantages:

(1) Due to the design of the overall device of this creation, it can not only achieve the purpose of water replenishment and water change, but also be a system device for drainage and water circulation filtration in the fish tank. Users do not need to purchase several sets of devices to perform different procedures. This creation does have Highly practical.

(2) Since this invention is equipped with two blocking valves and three sets of three-way reversing valves, it can effectively reduce the incomplete closing or the lack of siphon principle to discharge the water in the fish tank 300, or the water liquid is continuously replenished into the fish tank. 300, and can effectively avoid the death of organisms in the fish tank 300 due to insufficient water, lack of oxygen, or the overfull water causing organisms to jump out of the fish tank 300.

(3) Furthermore, since this invention is equipped with the pump filter cartridge 10 and the filtering device 40, it can not only filter the water liquid input into the fish tank 300 to prevent impurities, foreign matter and chlorine from being input into the fish tank 300 and harm the fish; but this invention also The water liquid discharged from the fish tank 300 is filtered to separate the impurities in the fish tank 300. Things will not be blocked in each three-way reversing valve or block valve and cause damage, thereby avoiding affecting the subsequent water change, water replenishment and circulation operations.

(4) In addition, this invention is further provided with a flow control valve 30, which can control the flow rate in the water pipe 20 to prevent the water flow rate into the fish tank 300 from being too fast, thereby preventing the pH value and temperature of the water in the fish tank 300 from being too fast. If the instantaneous change is too large, it will affect the environment of the fish tank 300 and avoid harm to the creatures in the fish tank 300.

(5) In addition, since the pump filter cartridge 10 of this invention is in a normally open state when the water is not being changed or replenished, it can provide continuous circulation filtration of the water in the fish tank 300, so that the water in the fish tank 300 can be maintained at a certain level. The oxygen amount and pH value can be filtered and blocked by foreign matter in the fish tank 300 to prevent foreign matter from remaining and causing fish to ingest it.

(6) In addition, since this invention is equipped with a control unit 200 and a human-machine interface 2001, it can not only be manually operated and remotely controlled according to needs, but also can be pre-set for water changes, water changes, etc. based on factors such as different types of fish and organisms, their quantity, etc. Numerical settings such as water replenishment-related cycle, time, water change amount, etc. allow the control unit 200 to automatically perform water change and water replenishment operations regularly and regularly according to these numerical settings (such as: small water change in one week, large water change in three weeks). Compared with For water changing operations that usually require manual operation, this invention truly achieves the convenience and practicality of automatically controlling water changing and replenishing at regular, quantitative and periodic intervals.

Therefore, from the above, it can be seen that this creation is indeed progressive and practical, and its structure is indeed unprecedented, and it has met the requirements for a new patent. I file a patent application in accordance with the law and pray for the patent to be granted. I am very grateful. Virtue and convenience.
