[0030] like Figure 1-9As shown, an aquarium air pump with a filter device includes a housing 1. The housing 1 is divided into a receiving cavity 3 and an air inlet cavity 4 by a partition 2. The receiving cavity 3 and the air inlet cavity 4 are interconnected by a connecting hole 5. An air pumping device 6 is provided in the receiving cavity 3. The air outlet 7 of the air pumping device 6 extends out of the housing 1. An air inlet hole 8 connected to the air inlet cavity 4 is provided on the outer wall of the housing 1. A gas filter element 9 is provided in the air inlet cavity 4 between the connecting hole 5 and the air inlet hole 8. Gas enters the air inlet cavity 4 from the air inlet hole 8, passes through the gas filter element 9, and then enters the air inlet end of the air pumping device 6 through the connecting hole 5.

[0031] The gas filter element 9 described in this invention can be made of detachable or replaceable filter materials such as activated carbon filter cotton, which can effectively intercept dust, microorganisms and other tiny particles as well as tobacco smoke, ensuring that the air entering the air pump device 6 is clean, preventing pollutants from entering the aquarium water, and improving water quality safety.

[0032] In the first embodiment of this utility model, a cover plate 10 covering the air intake chamber 4 is provided on the outer wall of the housing 1. The cover plate 10 is fixedly connected to the housing 1 by screws 11, and the air intake hole 8 is provided on the cover plate 10. In this utility model, the air intake hole 8 is located at the end near the air outlet 7, and the connecting hole 5 is located at the end away from the air outlet 7, effectively extending the air flow path in the air intake chamber 4, so that the gas filter 9 can fully filter the air. After the air enters the air intake chamber 4 through the air intake hole 8, it first passes through the gas filter 9 and then enters the connecting hole 5. In this utility model, multiple screw posts are arranged at intervals in the air intake chamber 4, and the screws 11 are screwed onto the screw posts. The gas filter 9 is provided with clearance through holes at the corresponding positions of the screw posts, and the screw posts are located in the clearance through holes. When it is necessary to replace the gas filter 9, it is only necessary to remove the screws 11 from the housing 1 and open the cover plate 10 for replacement.

[0033] In this invention, multiple shock-absorbing pads 12 are provided on the cover plate 10. Hanging ears 13 are also provided on the cover plate 10. In use, the cover plate 10 can be hung on the outer wall of the aquarium via the hanging ears 13, and the shock-absorbing pads 12 can effectively reduce the vibration of the air pump.

[0034] In this invention, a positioning recess 14 is provided on the housing 1 on the outer periphery of the air intake cavity 4, and the cover plate 10 presses against the positioning recess 14. The positioning recess 14 limits the cover plate 10, effectively preventing the cover plate 10 from moving and ensuring better alignment and positioning of the screw 11 and the screw post.

[0035] In the first embodiment, when used for a long time, the gas filter 9 near the air inlet 8 may become clogged or experience poor airflow. To address this problem, the present invention improves upon it in the following way: In the second embodiment of the present invention, based on the first embodiment, multiple air intake adjustment mechanisms 15 are provided on the cover plate 10 to adjust the air intake position. Each air intake adjustment mechanism 15 includes mounting slots 16 spaced apart on the cover plate 10 along the gas flow direction. The mounting slots 16 are interconnected with the air intake chamber 4. An adjusting cylindrical switch 17 is provided in each mounting slot 16, and the air inlet 8 is located on the adjusting cylindrical switch 17. In this invention, the air inlet 8 and the air intake chamber 4 can be interconnected or closed by adjusting the adjusting cylindrical switch 17 at different positions, thereby adjusting the air intake at different positions. In this invention, shaft holes are provided on both sides of the mounting slots 16, and rotating shafts are provided at both ends of the adjusting cylindrical switch 17, with the rotating shafts movably disposed within the shaft holes. Limiting grooves communicating with the shaft hole are provided on both the front and rear sides of the mounting slot 16. Two positioning protrusions are provided at corresponding positions on the rotating shaft and the limiting grooves. When the air inlet 8 is open, one of the positioning protrusions is engaged with the upper limiting groove. When the air inlet 8 is closed, the other positioning protrusion is engaged with the lower limiting groove.

[0036] In the third embodiment of this utility model, multiple insertion slots 18 are provided at intervals at corresponding positions on the housing 1 and the air intake chamber 4, and the gas filter element 9 is inserted into the insertion slots 18. Relief slots 19 are respectively provided on both sides of the housing 1 to facilitate the removal of the gas filter element 9. In this embodiment, the gas filter element 9 includes a frame, and activated carbon filter cotton is disposed within the frame. A baffle is provided at the corresponding position on the air intake chamber 4 and the frame to ensure that air passes through the gas filter element 9. In this embodiment, the gas filter element 9 is installed on the housing 1 or the cover plate 10 by insertion, allowing the gas filter element 9 to be replaced while the air pump is operating. The insertion method makes replacement more convenient and quick.

[0037] The air pumping device 6 of this utility model includes an air chamber seat 20, with air chambers 21 symmetrically arranged on both sides of the air chamber seat 20. An air inlet slot 22 is provided on the air chamber seat 20, and an air inlet hole 23 is provided within the air inlet slot 22 to connect the air chamber 21 and the air inlet slot 22. An air inlet valve 24 is provided within the air chamber 21 to control the opening and closing of the air inlet hole 23. An air outlet channel is provided within the air chamber seat 20, and an air outlet 7 is connected to the air outlet channel. An air outlet seat 25 is provided on the outer wall of the chamber seat 20, which can connect the air chamber 21 and the air outlet channel. An air outlet hole 26 is provided in the air outlet seat 25, and an air outlet valve 27 is provided in the air outlet seat 25. A leather cup 28 is connected to the air chamber 21. The leather cup 28 is connected to the swing arm 29. A magnet 30 is provided at one end of the swing arm 29, and the other end of the swing arm 29 is installed on the air chamber seat 20 through a shock-absorbing sleeve 31. An electromagnet 32 ​​is provided in the housing 1 at the position corresponding to the magnet 30.

[0038] When electromagnet 32 ​​is energized, it generates an alternating magnetic field, which interacts with magnet 30 on swing arm 29, causing swing arm 29 to oscillate back and forth. Swing arm 29 is damped by shock absorber sleeve 31 and drives cup 28 to reciprocate within air chamber 21. When cup 28 moves out of air chamber 21, negative pressure is created within air chamber 21, inlet valve 24 opens, and air enters air chamber 21 from inlet slot 22 through inlet hole 23. Exit valve 27 closes at this time to prevent gas backflow. When cup 28 moves into air chamber 21, air pressure increases, inlet valve 24 closes, and outlet valve 27 opens. Compressed air enters outlet channel through outlet hole 26 and is finally discharged from outlet 7, providing oxygen to the fish tank. In this invention, electromagnet 32 ​​is periodically energized and de-energized, driving swing arm 29 to oscillate continuously, causing cup 28 to reciprocate, achieving continuous intake and exhaust, and forming a stable airflow output. The symmetrical design of the dual air chambers 21 improves gas delivery efficiency. The shock-absorbing sleeve 31 and the leather cup 28 structure effectively reduce mechanical vibration and noise. By driving the movement of the leather cup with an electromagnet and combining it with valve control, a stable and low-noise aquarium oxygenation function is achieved.
