Description

Technical Field

[0001] This utility model relates to aquarium filtration equipment, and more particularly to a forced filtration type aquarium filter. Background Technology

[0002] Wall-mounted aquarium filters are commonly used filtration devices in ornamental fish keeping. However, existing wall-mounted aquarium filters rely on a water pump to draw water out and directly flush it onto various filter media for filtration before returning it to the aquarium. This filtration method has poor filtration performance because it uses the water's own gravity to flow through the filter media. The filtration kinetic energy depends entirely on the sinking gravity of the water. After a period of use, the impurities filtered by the filter media will cause some blockage, creating filtration resistance. As a result, water will flow directly past the filter media, causing the filter to lose its filtration effect. Therefore, the filtration efficiency is low and the filtration effect is poor.

Detailed Implementation

[0017] The exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, in the drawings, the same reference numerals are assigned to components that are substantially the same in structure and function, and redundant descriptions of substantially the same components have been omitted to make the description more concise.

[0018] like Figures 1-6As shown, a forced filtration aquarium filter includes a housing 1 that can be installed on an aquarium. The top of the housing 1 is open. The housing 1 includes a filter housing 2. The filter housing 2 has a closed filter basket inside for placing filter media to filter water. The filter media can be common filter media such as filter cotton. The filter basket has filter holes 42 distributed on it, and a gap 5 is left between the filter basket and the filter housing 2. Support protrusions 6 can be provided on the inner wall of the filter housing 2. The filter basket is placed between these support protrusions 6. The gap 5 between the filter basket and the filter housing 2 is left by these support protrusions 6 to allow water to flow through. A water inlet housing 3 that can extend into the aquarium is connected to the upper side of the filter housing 2. The filter housing 2 and the water inlet housing 3 are integrally formed to form the housing 1, which has a simple structure. The water inlet housing 3 has a water inlet 31. A water pump device is connected to the bottom of the water inlet housing 3. The water pump device is connected to the filter basket through the water inlet channel. A return flow structure is provided on the top of the filter housing 2 on the same side as the water inlet housing 3 to guide the water back to the aquarium. When in operation, this utility model is installed on a fish tank. Filter media is placed in the filter basket, and the upper water housing 3 extends into the water in the fish tank. Water enters the upper water housing 3 through the inlet 31. The pump device connected to the bottom of the upper water housing 3 forces water through the upper water channel into the filter basket for filtration by the filter media. The filtered water enters the gap 5 between the filter basket and the filter housing 2 through the filter holes 42, and then flows back into the fish tank through the return structure. The pump device, connected to the filter basket through the upper water channel, establishes a complete filtration water flow pipeline, preventing water from overflowing the filter media and improving the filtration effect. The inlet 31 can use vertically arranged grid holes to adapt to different water levels, improve the water intake effect, and also facilitate the intake and removal of oil film on the water surface in the fish tank.

[0019] like Figure 2 and 6 As shown, the water pumping device includes a pumping chamber 7, within which a water pump 8 is installed. The water pump 8 can be a commonly used type in aquarium filtration equipment. The water pump 8 is detachably installed at the bottom of the pumping chamber 7 via a pump base cover 81. The outlet of the water pump 8 is connected to the water supply channel. When the water pump 8 operates, water entering the upper water housing 3 through the inlet 31 is forcibly fed into the filter basket for filtration through the water supply channel. The bottom of the pumping chamber 7 has an inlet regulating port 10, and an inlet regulating plate 11 is slidably mounted at the inlet regulating port 10 at the bottom of the pumping chamber 7. A bottom cover 9 can be snapped onto the bottom of the pumping chamber 7, with the inlet regulating port 10 mounted on the bottom cover 9, facilitating the disassembly, replacement, and cleaning of the water pump 8. The opening of the inlet regulating port 10 is adjusted by sliding the inlet regulating plate 11 to varying degrees of obstruction, thereby adjusting the water intake ratio between the upper and lower parts of the aquarium while ensuring the removal of impurities from the bottom of the aquarium.

[0020] like Figure 1 , 4As shown in Figure 6, at least one bottom suction extension housing 12 is detachably plugged into the bottom of the upper water housing 3. The bottom end of the bottom suction extension housing 12 is detachably plugged into the pump chamber 7. This detachable plugging of the bottom suction extension housing 12 with the upper water housing 3 and the pump chamber 7 allows for adjustable length of the upper water section of the filter, adapting to aquariums of different depths. It also allows for the use of different power water pumps 8 for aquariums of different depths, ensuring proper filtration. Alternatively, the bottom suction extension housing 12 can be omitted, and the upper water housing 3 and the pump chamber 7 can be directly detachably plugged into each other to accommodate shallow aquariums. A wire channel 13 can be provided on the outside of the upper water housing 3, the bottom suction extension housing 12, and the pump chamber 7 for wiring the water pump wires.

[0021] like Figure 4 and 6 As shown, the water supply channel includes a lower pipe 14 installed in the pump chamber 7, an intermediate pipe 15 installed in the bottom suction extension housing 12, and a connecting pipe 16 installed in the upper water housing 3. After the pump chamber 7, bottom suction extension housing 12, and upper water housing 3 are connected, the lower pipe 14, intermediate pipe 15, and connecting pipe 16 are connected together. The connecting pipe 16 connects to the top of the filter basket via a connecting water pipe 18, which is equipped with a flow regulating valve 17. The lower pipe 14, intermediate pipe 15, and connecting pipe 16, which are installed in the pump chamber 7, bottom suction extension housing 12, and upper water housing 3 respectively, facilitate the forced water supply from the water pump 8 to the filter basket and allow for easy adjustment of the water supply channel by adding or removing the bottom suction extension housing 12 to accommodate aquariums of different depths. The connecting water pipe 18 can be assembled using common fittings such as elbows and water pipes, and the flow regulating valve 17 can also be a common knob-type flow regulating valve for adjusting the forced water supply flow.

[0022] like Figures 3-6 As shown, the filter basket includes a basket body 4 with a top opening. The top opening of the basket body 4 is covered with a basket cover 41, which facilitates the replacement and sealing of the filter media inside the basket, thus enclosing the entire filter basket. The filter holes 42 are located at the bottom of the basket body 4. The water inlet channel passes through the basket cover 41 and connects to the filter basket, so that the water that the water pump 8 forces to deliver to the filter basket can only be filtered from the top of the filter media inside the basket and discharged from the bottom, without any unfiltered water, thus improving the filtration effect.

[0023] like Figure 1 and 3As shown, a stepped hanging groove 19 with a downward-facing opening is provided between the filter housing 2 and the water supply housing 3. This allows for easy installation of the filter and the aquarium by simply hanging the filter housing 2 and the water supply housing 3 onto the top of the aquarium's side wall via the hanging groove 19. The stepped hanging groove 19 can accommodate aquariums of varying wall thicknesses. The return flow structure includes a return port 20 on the filter housing 2, which connects to the inner cavity of the filter housing 2. A downward-sloping guide plate 21 extends into the aquarium from the bottom outer side of the return port 20. The downward-sloping guide plate 21 guides the water flowing from the return port 20 back into the aquarium with potential energy, creating a waterfall-like effect. This not only enhances aesthetics but also provides a certain impact and stirring effect on the water in the aquarium, increasing dissolved oxygen levels. Furthermore, a stepped hanging groove 19 can also be provided between the bottom of the guide plate 21 and the filter housing 2 to improve the balance of the connection.

[0024] like Figure 1 and 6 As shown, a top cover 22 is provided at the top opening of the housing 1 to cover the internal components of the filter housing 2 and the water supply housing 3, preventing impurities and foreign objects from falling in and ensuring the normal operation of the filter. An eccentric adjustment block 23 is rotatably provided on the bottom of the filter housing 2 near the water supply housing 3. The eccentric adjustment block 23 and the filter housing 2 can be damped and rotated together. By rotating the eccentric adjustment block 23 and engaging with the outer side wall of the aquarium, the tilt and verticality between the filter housing 2 and the water supply housing 3 and the aquarium side wall can be adjusted, making it more suitable for the filter's operation.

[0025] In use, filter media such as filter cotton are placed in the filter basket, and the filter basket and housing 1 are sealed. Then, the filter is hung on the side wall of the aquarium through the mounting slot 19 and the position is adjusted by rotating the eccentric adjustment block 23. After that, the water pump 8 works, and the water in the aquarium and the oil film on the water surface enter the upper water housing 3 through the water inlet 31. Under the suction of the water pump 8, the water flows down to the pump chamber 7 and is sent into the upper water channel by the water pump 8. Then it is forced to be transported to the filter basket, where it flows down from the top of the filter cotton for filtration and is discharged from the bottom into the filter housing 2. After that, it flows back to the aquarium in a waterfall shape through the return port 20 and the guide plate 21, realizing the circulation filtration of water in the aquarium. During filtration, the water inlet ratio of the upper and lower parts of the aquarium can be adjusted by sliding the water inlet adjustment plate 11 to ensure the removal of impurities from the bottom of the aquarium.
