Description

Technical Field

[0001] This utility model relates to the field of aquarium filter barrel technology, and in particular to a filter barrel with a pull-out water intake mechanism. Background Technology

[0002] Aquarium canister filters are typically equipped with a water pump to ensure water circulation and filtration. However, the water pump must undergo a priming process when first started, which involves filling the canister with water so that the pump can operate properly. This process is a necessary step in starting the water pump.

[0003] Traditional methods of adding water typically involve disassembling the filter canister, a tedious and time-consuming process, especially during aquarium maintenance. Users need to first turn off the water pump, remove the filter canister cap, manually add water, and finally reassemble the filter canister and start the water pump.

[0004] In addition, frequent disassembly and assembly of the filter cartridge can cause wear and tear on the equipment, reducing its service life.

[0005] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and this utility model is made based on this situation. Utility Model Content

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figures 1 to 7 As shown, this utility model provides a filter bucket with a pull-out water intake mechanism, which aims to simplify the water intake process and improve the starting efficiency of the water pump. The filter bucket mainly includes a bucket body 1 and a bucket cover 2. The bucket cover 2 is provided with a water inlet 3 and a water outlet 4 for connecting to external pipelines.

[0030] The tank 1 is equipped with a filter assembly 5 for filtering water. A water pump assembly 6 is located between the water outlet 4 and the filter assembly 5 to draw water from the fish tank and discharge the filtered water from the filter tank.

[0031] A key feature of this invention is that a pull-out water-drawing component 7 is provided between the water inlet nozzle 3 and the filter assembly 5 for manually drawing water into the tank 1 before the water pump assembly 6 is started. This pull-out water-drawing component 7 allows water to be drawn in through simple manual operation without disassembling the filter tank, greatly improving ease of use.

[0032] Specifically, the pull-out water intake assembly 7 includes a cylinder 71, the upper end of which is connected to the water inlet 3, allowing water entering from the outside through the water inlet to enter the cylinder 71. The lower end of the cylinder 71 is connected to the filter assembly 5, preferably to the water inlet channel of the filter assembly 5.

[0033] A piston 72 is installed inside the cylinder 71, and the piston 72 can move up and down within the cylinder 71. A one-way valve structure is provided at the piston 72, which allows water to pass through the piston when it moves in a specific direction, and blocks water from passing through when it moves in the other direction, thereby achieving the pumping function. A push-pull rod 73 is connected to the piston 72, which passes through the lid 2 and extends outside the lid 2, allowing the user to manually push and pull it.

[0034] In a preferred embodiment of this utility model, the one-way valve structure includes a mounting groove 721 located on the side of the piston 72. A sealing ring 74, movable up and down within the mounting groove 721, is provided. The outer diameter of the sealing ring 74 is slightly larger than the inner diameter of the cylinder 71, and it forms a tight seal with the inner wall of the cylinder 71. A through hole 722, connecting the upper and lower sides of the piston 72, is provided at the bottom of the mounting groove 721.

[0035] The working principle of this one-way valve structure is as follows:

[0036] Due to the friction between the sealing ring 74 and the inner wall of the cylinder 71, the sealing ring 74 moves as the piston 72 moves up and down. When the sealing ring 74 moves up to the top of the mounting groove 721 as the piston 72 moves down, the sealing ring 74 is squeezed by the inner wall of the cylinder 71 and the top of the mounting groove 721, forming a tight seal between the piston 72, the sealing ring 74, and the inner wall of the cylinder 71. At this time, a negative pressure is formed above the piston 72 (on the side of the water inlet 3), drawing water from the aquarium into the water inlet 3 and then into the cylinder 71. Meanwhile, a positive pressure is formed below the piston 72 (on the side of the filter assembly 5), pushing the water below the piston 72 downwards into the filter assembly 5.

[0037] When the sealing ring 74 moves down to the bottom of the mounting groove 721 as the piston 72 moves upward, the upper and lower sides of the piston 72 are connected through the through hole 722, allowing water above the piston 72 to flow through the through hole 722 to the bottom of the piston 72 and enter the lower space of the cylinder 71 or the water inlet channel of the filter assembly 5; of course, it also allows air in the lower space of the cylinder 71 to reach the top of the piston 72 through the through hole 722.

[0038] To ensure the effectiveness of the one-way valve structure, more preferably, the outer diameter M of the piston 72 is smaller than the inner diameter N of the cylinder 71, allowing the sealing ring 74 to move up and down within the mounting groove 721. Simultaneously, the diameter D of the sealing ring 74 is smaller than the height H of the highest point of the through hole 722 from the bottom surface of the mounting groove 721, ensuring that the sealing ring 74 does not completely block the through hole 722 when it falls into the bottom of the mounting groove 721, thereby ensuring that water can pass through the through hole 722.

[0039] As a further preferred embodiment of this utility model, the piston 72 can disengage from the lower end of the cylinder 71, and the lower end of the cylinder 71 has space for the piston 72 to disengage. This means that during the priming operation, the piston 72 moves up and down within a predetermined stroke of the cylinder 71. After priming is completed, the user pushes the push-pull rod 73 completely downwards, causing the piston 72 to move to the lowest position of the cylinder 71 and disengage from the cylinder 71. In this position, the piston 72 is designed to move downwards out of the lower opening of the cylinder 71. For example, this can be achieved by designing the diameter of the lower part of the piston 72 to be slightly smaller than the diameter of the lower opening of the cylinder 71, or by providing a structure at the lower end of the cylinder 71 that allows the piston to pass through. After the piston 72 disengages downwards from the cylinder 71, the lower end of the cylinder 71 is completely open, allowing the water channel between the inlet nozzle 3 and the filter assembly 5 (i.e., inside the cylinder 71) to be unobstructed vertically, forming a smooth passage. This greatly reduces the resistance when water flows through the priming assembly 7, avoiding any impact on the normal pumping flow and efficiency of the main water pump assembly 6.

[0040] In a preferred embodiment of this utility model, the filter assembly 5 includes several stacked filter baskets 51. The bottom surface of each filter basket 51 is hollowed out to allow water to flow. Filter elements (not shown in the figure), such as filter cotton, activated carbon, ceramic rings, and other filter materials, are installed in each filter basket 51.

[0041] More preferably, the filter basket 51 is also provided with a water pipe 52. The water pipes 52 on adjacent filter baskets 51 are connected to each other to form a water inlet channel from the pull-out water inlet assembly 7 to the bottom of the barrel 1. The upper end of the water pipe 52 on the uppermost filter basket 51 is connected to the lower end of the barrel 71, and the lower end of the water pipe 52 on the lowermost filter basket 51 extends to the bottom of the lowermost filter basket 51. This design ensures that during the water inlet operation, the water can smoothly enter the bottom of the filter assembly 5 through the water pipe 52 and flow from bottom to top through each filter element for filtration.

[0042] In a preferred embodiment of this utility model, the water pump assembly 6 includes a motor 61 and an impeller 62 that is drivenly connected to the motor 61. The impeller 62 is disposed in a water channel leading to the outlet nozzle 4. The motor 61 drives the impeller 62 to rotate, thereby generating water flow, drawing the filtered water out of the filter assembly 5, through the water channel where the impeller 62 is located, and finally discharging it from the filter tank through the outlet nozzle 4.

[0043] To facilitate user operation of the push-pull lever 73, more preferably, the top of the push-pull lever 73 is provided with a handle ring 731. The handle ring 731 provides a convenient gripping point, allowing the user to easily pull the push-pull lever 73 upwards or downwards.

[0044] To further enhance the flexibility and safety of the filter canister, preferably, an inlet valve 31 is provided at the inlet nozzle 3, and an outlet valve 41 is provided at the outlet nozzle 4. These valves can be manual or automatic valves, used to control the opening and closing of the inlet and outlet water. For example, during maintenance or water priming operations, the outlet valve 41 can be closed to prevent backflow of water; when connecting to external pipelines, the inlet valve 31 can be used to control the water intake.

[0045] For ease of maintenance and cleaning, preferably, the inlet nozzle 3, outlet nozzle 4, water pump assembly 6, and pull-out water intake assembly 7 are all detachably connected to the lid 2. For example, detachable connections can be achieved using threaded connections, snap-fit ​​connections, or sealing ring-assisted insertion. This design allows users to easily remove these components from the lid for cleaning, repair, or replacement.

[0046] Similarly, to facilitate maintenance or replacement of the filter components inside the canister, the canister body 1 and the canister lid 2 are detachably connected. For example, a snap-fit, fastener, thread, or sealing ring can be used to achieve a tight connection and easy disassembly between the canister body 1 and the canister lid 2.

[0047] When using the filter canister of this invention, first ensure that the inlet nozzle 3 is connected to an external water source pipe (usually a fish tank), and the outlet nozzle 4 is connected to an outlet pipe. Before starting the water pump assembly 6, if there is air in the pipe, water can be introduced by manually operating the pull-out water introduction assembly 7. When the push-pull rod 73 is pulled upward, the piston 72 moves upward, the sealing ring 74 falls into the bottom of the mounting groove 721, and the through hole 722 opens, allowing water (or a small amount of air) below the piston 72 to reach above the piston through the through hole 722. When the push-pull rod 73 is pushed downward, the piston 72 moves downward, the sealing ring 74 is pushed to the top of the mounting groove 721, forming a seal, and a negative pressure is generated below the piston 72. External water enters the bottom of the filter assembly 5 through the inlet nozzle 3, the upper end of the tank body 71, the lower end of the tank body 71, and the water pipe 52, filling the filter canister upward. Repeating this push-pull operation will expel the air from the filter canister and complete the water introduction. Once the water is introduced, the water pump assembly 6 can be started, and the water pump will discharge the filtered water from the outlet 4.

[0048] Through the above structural design, this utility model provides a filter canister that is easy to operate and has high water diversion efficiency, especially suitable for applications that require overcoming a certain head or removing air from the pipeline. Users can complete water diversion by pulling or pushing the filter canister without disassembling, tilting, or moving it, significantly improving ease of use.

[0049] The above are merely preferred embodiments of this utility model. Those skilled in the art can make various modifications and variations based on this, and all such modifications and variations should fall within the scope defined by the appended claims of this utility model.
