[0029] Reference Figures 1 to 6The utility model proposes a water-changeable hanging cylinder filter, which is characterized in that it includes a hanging cylinder shell 1, a filter assembly arranged inside the hanging cylinder shell 1, a mounting base 2 arranged on the hanging cylinder shell 1, and a water pump assembly 3 installed on the mounting base 2. The hanging cylinder shell 1 is provided with a first hanging groove 11 with an opening facing downward, which can be used to hang it on the fish tank. The water outlet end of the water pump assembly 3 is connected to a drainage pipe 4 that can guide water flow to the inside of the hanging cylinder shell 1. The upper part of the hanging cylinder shell 1 is provided with a water outlet 12, and the end of the drainage pipe 4 is detachably installed with a water change joint 5.

[0030] Preferably, the mounting base 2 is provided with a flow guide hole 21, the water outlet end of the water pump assembly 3 is connected to the lower end of the flow guide hole 21, the drainage pipe 4 includes an L-shaped pipe 41 and a water outlet pipe 42 connected to the end of the L-shaped pipe 41, the head end of the L-shaped pipe 41 is inserted in the flow guide hole 21 and can rotate in the flow guide hole 21, a sealing ring 83 is provided between the L-shaped pipe 41 and the flow guide hole 21, and the sealing ring 83 adopts a rotating sealing ring. When the L-shaped pipe 41 rotates relative to the mounting base 2, the end of the water outlet pipe 42 rotates to the top of the hanging cylinder shell 1 or moves away from the top of the hanging cylinder shell 1. Preferably, the head end of the L-shaped pipe 41 also slides with the inner side wall of the flow guide hole 21 so that the L-shaped pipe 41 can also move up and down along the flow guide hole 21.

[0031] When the utility model is used to filter water in a fish tank, the hanging tank shell 1 is hung on the glass of one side of the fish tank through the first hanging groove 11, and the water changing joint 5 on the drainage pipe 4 is in a disassembled state. After the filter is started, the water pump assembly 3 pumps the water in the fish tank, and the water flows into the inside of the hanging tank shell 1 through the drainage pipe 4. After being filtered by the filter assembly in the hanging tank shell 1, the filtered water flows out from the water outlet 12 on the hanging tank shell 1 and returns to the fish tank. In this way, waste such as fish feces can be removed, so that the water in the fish tank is kept clean.

[0032] Preferably, the water outlet pipe 42 is an L-shaped curved pipe with its water outlet facing downward. With such a design, when the filter is used for filtering, the water drawn out from the bathtub can accurately enter the inner cavity of the hanging tub shell 1 without spilling out.

[0033] Reference Figure 3 The filter assembly includes a partition 71 disposed in the hanging cylinder shell 1, a carbon bag 72 disposed downstream of the partition 71, and a filter cotton 73 disposed downstream of the carbon bag 72. After the water in the fish tank is pumped into the inner cavity of the hanging cylinder shell 1, it first passes through the partition 71 to filter out the large particles therein, and then passes through the carbon bag 72 and the filter cotton 73 to remove the small particle pollutants therein. Finally, the filtered water flows out from the water outlet 12 on the hanging cylinder shell 1 and returns to the fish tank.

[0034] When you need to change the water in the fish tank, you can use the following methods.

[0035] Method 1: Install a water changing joint 5 at the end of the drainage pipe 4, and then directly put a hose on the water changing joint 5. After turning on the water pump assembly 3, the water in the fish tank can be discharged to the sewer, pool or other location through the hose, and then new water is added to the fish tank. In order to improve the connection tightness between the water changing joint 5 and the hose, a plurality of annular inverted teeth 51 are provided on the outer side wall of the end of the water changing joint 5.

[0036] Method 2: When the drainage tube 4 can be directly rotated and will not be blocked, the drainage tube 4 can be directly rotated to a certain angle so that the water outlet end of the water outlet pipe 42 is rotated to the top of the hanging cylinder shell 1 or moved away from the top of the hanging cylinder shell 1, and then a water changing joint 5 is installed at the end of the drainage tube 4, and the water in the fish tank is directly discharged to the outside of the hanging cylinder shell 1 through the water changing joint 5, such as a sewer, a pool or other locations.

[0037] Method three: when the drainage tube 4 cannot be rotated directly, the drainage tube 4 can be first lifted up to a certain height, and then the drainage tube 4 can be rotated at a certain angle to rotate the water outlet end of the outlet pipe 42 to the top of the hanging cylinder shell 1 or move away from the top of the hanging cylinder shell 1, and then a water changing joint 5 is installed at the end of the drainage tube 4, and the water in the fish tank is directly discharged to the outside of the hanging cylinder shell 1, such as a sewer, a pool or other locations through the water changing joint 5 or the hose installed on the water changing joint 5.

[0038] The water changing joint 5 and the water outlet pipe 42 can adopt the following connection structure: first, the water changing joint 5 and the water outlet pipe 42 are threadedly connected. Second, the outer side wall of the end of the water outlet pipe 42 is provided with a circumferential groove 421 and an axial groove 422 connected to the circumferential groove 421, and the head end of the water changing joint 5 has a plug hole for the end of the water outlet pipe 42 to be inserted therein, and the inner side wall of the plug hole is provided with a block 52 that can be inserted into the axial groove 422 and can be transferred from the axial groove 422 to the circumferential groove 421. Compared with the threaded connection method, this connection structure is faster to assemble and disassemble the water changing joint 5.

[0039] Furthermore, the L-shaped tube 41 is provided with a knob switch 81 capable of adjusting the internal flow rate thereof. The knob switch 81 is installed at the turning point of the L-shaped tube 41, and includes an exposed screw head and a cylinder inserted in the horizontal section of the L-shaped tube 41. A through hole is provided on one side of the cylinder. When the through hole faces downward, the flow rate in the L-shaped tube 41 is maximum. In the process of turning the knob switch 81 180 degrees, the flow rate will gradually decrease. When the through hole faces upward, the flow rate is reduced to a minimum value or to zero.

[0040] Reference Figure 1The water pump assembly 3 includes a water pump 31, a water suction pipe 32 connected to the water inlet end of the water pump 31, and a water guide pipe 33 connected to the water outlet end of the water pump 31.

The water suction pipe 32 is a basket-shaped one to prevent the inhalation of larger particles from causing blockage.

[0041] Further, a suction cup 82 capable of adsorbing the water conduit 33 to the fish tank is installed on the water conduit 33. By adsorbing the water conduit 33 to the fish tank through the suction cup 82, the water conduit 33 can withstand the impact of the water flow in the fish tank, and the water pump assembly 3 is prevented from being subjected to radial impact force and loosening the connection.

[0042] Furthermore, the mounting base 2 is provided with a second hanging groove 22 with an opening facing downwards, which can be used to hang it on the fish tank, and the mounting base 2 is detachably connected to the hanging tank shell 1 so that the hanging tank shell 1 can be removed upwards relative to the mounting base 2. Specifically, the upper part of the hanging tank shell 1 is provided with a slot 13 with an opening facing downwards, and the upper surface of the mounting base 2 is provided with an insert block 23, which is inserted into the slot 13 so that the mounting base 2 is detachably connected to the hanging tank shell 1. By adopting such a design, the hanging cylinder can be removed separately for cleaning. The method of removing the hanging cylinder is to first lift the drainage pipe 4 upward to a certain height, and then rotate the drainage pipe 4 to a certain angle so that the water outlet end of the outlet pipe 42 is rotated to the top of the hanging cylinder shell 1 or moved away from the top of the hanging cylinder shell 1, and then the hanging cylinder shell 1 and the filter assembly therein can be lifted upward together to remove the hanging cylinder. After the hanging cylinder is removed, the mounting base 2, the water pump assembly 3, and the drainage pipe 4 are still installed on the fish tank to prevent water on these components from spilling onto the ground. After the hanging cylinder is removed, the remaining components can also be used to change the water in the fish tank.
