[0002] An electric aquarium water changer is a fishkeeping device that uses an electric water pump to generate suction to extract water from the aquarium. It can improve water changing efficiency, save water changing time, and clean the aquarium.

[0003] Because the handle of an electric aquarium water changer typically houses the power supply and circuit board, it cannot be used while submerged in water. However, the operating environment for electric aquarium water changers is often humid, and the handle is prone to contact with water or falling into it. Existing electric aquarium water changers often have poorly sealed circuit compartments, and water ingress can lead to circuit board corrosion, motor short circuits, or even damage to the device.

[0004] It is evident that improving the waterproof performance of electric aquarium water changers is a problem that urgently needs to be solved. Utility Model Content

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] The purpose of this invention is to provide a fish tank water changer to solve the problems existing in related technologies and to have good waterproof performance.

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1-5 As shown, this embodiment provides a fish tank water changer, including a handle 1, an inlet pipe 2, an outlet pipe 3, and a water pump 4. The handle 1 includes a housing, a connecting pipe 5, a sealed chamber 6, a power supply, a circuit board, and a control panel 7. The housing has a water path area 101 and a circuit area 102. An inlet pipe connection port and an outlet pipe connection port are located near the water path area 101 on the housing, and a control panel mounting port is located near the circuit area 102 on the housing. Specifically, as shown... Figure 3As shown, the outer shell in this embodiment is a structure composed of an upper shell 8 and a lower shell 9. The outer shell is L-shaped. The water inlet is located at the end of the first straight edge of the outer shell, the water outlet is located at the end of the second straight edge of the outer shell, and the control panel mounting port is located at the end of the first straight edge of the outer shell away from the water inlet.

[0033] In this embodiment, the connecting pipe 5 is disposed in the water passage area 101; the outlet end of the inlet pipe 2 passes through the inlet pipe connection port and is connected to the inlet end of the connecting pipe 5; the inlet end of the outlet pipe 3 passes through the outlet pipe connection port and is connected to the outlet end of the connecting pipe 5; the water pump 4 is disposed at the inlet end of the inlet pipe 2 to pump water out of the fish tank; specifically, in this embodiment, the inlet pipe 2 is preferably a telescopic pipe, which is convenient to adjust the length of the inlet pipe 2 according to the depth of the fish tank, and the outlet pipe 3 is preferably a flexible hose, which is convenient to bend and adjust according to the position of the fish tank and the position of the drain outlet.

[0034] In this embodiment, the sealed chamber 6 is located in the circuit area 102, and both the power supply and the circuit board are located within the sealed chamber 6; the control panel 7 is located at the control panel mounting port, and the control panel 7, the circuit board, and the water pump 4 are all electrically connected to the power supply; specifically, as shown... Figure 2 As shown, in this embodiment, the motor of the water pump 4 is electrically connected to the power supply via the connecting wire 10, and the control panel 7 is equipped with a display screen 11 and multiple control buttons.

[0035] In this embodiment, the opening of the sealed chamber 6 is fixedly connected to the inside of the control panel 7 by screws, and a sealing ring is provided between the opening of the sealed chamber 6 and the inside of the control panel 7. That is, the sealed chamber 6 forms a sealed space in the circuit area 102 of the handle 1, which is locked with a sealing ring and screws. The power supply and circuit board are installed in the sealed chamber 6, which prevents water from entering and damaging the core circuit components of the aquarium water changer.

[0036] In this embodiment, the handle 1 also includes a flow meter 12 and a buzzer. The flow meter 12 is mounted on the connecting pipe 5, and the buzzer is mounted in the circuit area 102. Both the flow meter 12 and the buzzer are electrically connected to the power supply. Specifically, the flow meter 12 in this embodiment is preferably a turbine flow meter. When changing the water in the aquarium, the required water pumping volume is first set through the control panel 7, and then the water pump 4 is started to pump water. During this process, the water pumping volume is counted by the flow meter 12. When the water pumping volume reaches the predetermined value, the water pump 4 stops working, and the buzzer sounds an alarm, thus achieving precise water changing. Existing aquarium water changers usually require manual switching to control the water pumping volume, which is difficult to accurately match the aquarium volume and is prone to over-pumping water, endangering the survival of fish. During operation, someone must be next to the equipment. In contrast, this device has a quantitative water pumping function, is easy to operate, and saves time and effort.

[0037] In this embodiment, the aquarium water changer also includes a sand-washing head 13, which is located at the water inlet of the water pump 4. During water changes, the sand-washing head 13 can clean the sand at the bottom of the aquarium. The sand-washing head 13 is a common aquarium cleaning tool on the market, and its structure and working principle will not be described in detail here.

[0038] In this embodiment, the power source is a lithium battery. Existing aquarium water changers typically require connection to mains power, meaning they operate plugged in. These devices are bulky, and because they need to be moved to clean and scrape algae from the aquarium walls or wash sand from the bottom, corded operation is inconvenient. The power cord can hinder movement, prolonging cleaning time. Furthermore, frequent dragging of the power cord can damage it and pose a risk of electrical leakage. In contrast, this device uses a lithium battery power supply, providing wireless water changing and sand washing functions. It operates wirelessly, significantly improving efficiency, and features a simple structure and safe operation.

[0039] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
