Description

Technical Field

[0001] This invention relates to the field of aquarium technology, and more particularly to an aquarium with a filtration function. Background Technology

[0002] A fish tank is a container used to keep live fish. It adds enjoyment to life and has aesthetic value; keeping fish is a pleasant and relaxing hobby. However, after a period of use, impurities accumulate in the tank, requiring regular cleaning. Currently, manual cleaning is still the most common method. Keepers need to use tools to scoop out leftover food, fish waste, and other impurities from the water. This process is not only tedious and physically demanding, but the cleaning effect is often not thorough. Furthermore, it is difficult to monitor water temperature changes simultaneously during manual cleaning, and water temperature fluctuations are crucial for fish survival; ignoring this factor can easily cause discomfort or even death in fish.

[0003] The prior art patent document with publication number CN217564604U provides a fish tank with a filtration function; the device uses a motor as the driving force to drive the filter screen to move upward, thereby filtering and cleaning impurities in the fish tank. The water thermometer can measure the water temperature, and people can change the water in the fish tank according to the water temperature required by different types of fish, saving time and effort.

[0004] However, this device still has the following problems: When the filter screen is installed in the aquarium to clean impurities, it is easy for the screen to come into contact with ornamental fish, aquatic plants, artificial rocks, and other landscaping elements during its up-and-down movement. This mechanical movement may not only frighten or injure the fish, affecting their normal growth, but may also damage the carefully arranged landscape in the aquarium, reducing its ornamental value. Summary of the Invention

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fish tank with a filtration function, comprising a fish tank body and a circulation pump, wherein the circulation pump is fixedly installed on the outer end of the fish tank body, and an inlet pipe and an outlet pipe are fixedly installed on the upper and lower sides of the outer periphery of the fish tank body, respectively, and the inlet pipe and the outlet pipe are respectively connected to the input end and the output end of the circulation pump, respectively, and a filter is fixedly installed between the inlet pipe and the input end of the circulation pump, a rotating ring is rotatably installed inside the fish tank body, the rotating ring is C-shaped, the outlet pipe is interconnected with the inner cavity of the rotating ring, a drain pipe is fixedly installed on the inner side of the rotating ring, the inner end of the drain pipe is obliquely upward, a floating ring is provided on the upper side of the inner cavity of the fish tank body, a cleaning brush is provided between the floating ring and the rotating ring, the cleaning brush is in contact with the inner wall of the fish tank body, and an inlet connector is rotatably installed on the inner side of the floating ring, the inlet connector is interconnected with the inlet pipe.

[0007] In the aforementioned aquarium with a filtration function, the cleaning brush includes an upper rotating sleeve and a lower rotating sleeve. The lower rotating sleeve is rotatably mounted on the upper end of the rotating ring, and the inner cavities of the two are interconnected. The upper rotating sleeve is rotatably mounted on the lower end of the floating ring.

[0008] In the aforementioned fish tank with a filtration function, the lower rotating sleeve has an insertion cavity on its outer periphery, the upper rotating sleeve is inserted into the insertion cavity, and the upper rotating sleeve has a through hole on its outer periphery. A gear is fixedly installed at the lower end of the lower rotating sleeve, and a toothed ring is fixedly connected to the inner wall of the fish tank inside the rotating ring. The gear and the toothed ring are meshed together.

[0009] In the aforementioned fish tank with a filtration function, a sealing ring is fixedly installed inside the drain pipe, and one side of the sealing ring is fixedly installed to the sealing plate by a first spring, with the sealing plate and the sealing ring fitting together.

[0010] In the aforementioned fish tank with a filtration function, a limiting sleeve is fixedly installed in the inner cavity of the sealing ring via a connecting rod, a limiting rod that is plugged into and connected to the limiting sleeve is fixedly installed in the inner end of the sealing plate, and a first spring is fixedly installed between the limiting sleeve and the limiting rod.

[0011] In the above-mentioned fish tank with filtration function, a first rotating frame that communicates with the inner cavity of the water inlet connector is rotatably installed at the upper end of the water inlet connector, a connecting sleeve that communicates with the inner cavity of the water inlet pipe is fixedly installed on the fish tank body, and a second rotating frame that communicates with the inner cavity of the connecting sleeve is rotatably installed on the inner side of the connecting sleeve. The first rotating frame and the second rotating frame are rotatably connected, and their inner cavities are interconnected.

[0012] In the aforementioned aquarium with filtration function, the filter includes a movable seat and two fixed seats. The two fixed seats are fixedly connected to the outer wall of the aquarium body. A collection cylinder is inserted into the movable seat, and a filter screen is fixedly installed inside the collection cylinder.

[0013] In the aforementioned aquarium with a filtration function, a first rotating seat is fixedly installed around the two fixed seats, and a second rotating seat is fixedly installed around the movable seat.

The drain pipe is angled upwards, causing a rotating ring to spin as water sprays out, effectively rinsing the aquarium's decorations. A cleaning brush cleans the inner walls of the aquarium. Compared to the original device that cleans the water using a moving filter, this invention avoids damage to the fish and the aquarium decorations while significantly improving the cleaning effect on the aquarium's interior.

[0015] Second, this invention features a floating ring that moves up and down with changes in water level. This, combined with the insertion connection between the upper and lower rotating sleeves, ensures the cleaning brush height matches the water level in the aquarium. Furthermore, the meshing connection between the gear and the toothed ring allows the cleaning brush to rotate as the rotating ring rotates, improving the cleaning effect on the inner wall of the aquarium.

[0016] Third, the present invention allows the movable seat to be rotated through the rotatable connection between the movable seat and the two fixed seats, thereby enabling the installation and disassembly of the recovery cylinder within the movable seat, facilitating the recovery of water impurities. Furthermore, a retaining ring is provided to position and seal the contact area between the movable seat and the fixed seats after the recovery cylinder is installed. Attached Figure Description

[0025] The filter 5 includes a movable seat 52 and two fixed seats 51. The two fixed seats 51 are fixedly connected to the outer wall of the aquarium body 1. A collection cylinder 53 is inserted into the movable seat 52, and a filter screen 54 is fixedly installed inside the collection cylinder 53. A first rotating seat 55 is fixedly installed around the two fixed seats 51, and a second rotating seat 56 is fixedly installed around the movable seat 52. The second rotating seat 56 is rotatably installed between the two first rotating seats 55. The upper and lower parts of the inner cavity of the movable seat 52 are respectively provided with retaining rings 57 that insert into the inner walls of the two fixed seats 51. A movable rod 58 is fixedly installed around the retaining rings 57. The movable rod 58 is located inside the second rotating seat 56, and a second spring 59 is fixedly installed between the two movable rods 58 inside the second rotating seat 56.

[0026] The working principle and usage of this invention are explained in detail below: When cleaning the impurities inside the aquarium 1, the circulation pump 13 is turned on. Through the inlet pipe 11 and the outlet pipe 12, water can be drawn in from the upper side of the inner cavity of the aquarium 1 and discharged from the lower side of the inner cavity of the aquarium 1, thus achieving the effect of circulating and guiding the water. When the water passes through the filter 5, impurities in the water can be filtered. When water is discharged into the rotating ring 2 through the outlet pipe 12, the inner end of the drain pipe 21 is set at an angle upward, so that when the drain pipe 21 discharges water into the middle of the inner cavity of the fish tank 1, it can drive the rotating ring 2 to rotate. This can make the water discharge evenly and also rinse the artificial rocks and other landscaping in the middle of the inner cavity of the fish tank 1, thus improving the cleaning effect. During the rotation of the rotating ring 2, the meshing connection between the gear 36 and the toothed ring 37 can drive the cleaning brush 3 to rotate on the inner wall of the aquarium body 1, thereby achieving the effect of cleaning the impurities on the inner wall of the aquarium body 1. A sealing plate 43 and a sealing ring 4 are installed inside the drain pipe 21 and are connected to each other by a first spring 44. When the circulation pump 13 is turned on and water is injected into the drain pipe 21, the drain pipe 21 can be opened so that the water can be discharged outward. When the circulation pump 13 is turned off, the drain pipe 21 can be sealed to prevent the water inside the fish tank 1 from flowing back into the rotating ring 2 and to keep the inside of the rotating ring 2 clean. A floating ring 22 is installed so that when the water level inside the aquarium 1 moves, the floating ring 22 can move up and down accordingly. Firstly, it can ensure that the water inlet connector 23 can contact the upper surface of the water body. Together with the first rotating frame 25, the second rotating frame 26 and the connecting sleeve 24, the circulation pump 13 can absorb the water on the upper side of the inner cavity of the fish tank body 1 through the water inlet pipe 11. Secondly, it can drive the upper rotating sleeve 32 to move up and down, so as to adjust the height of the cleaning brush 3 when the water level changes, so that the height of the cleaning brush 3 matches the water level, ensuring the cleaning effect of the cleaning brush 3 on the inner wall of the aquarium body 1. The insertion cavity 33 is set, and through its insertion connection with the upper rotating sleeve 32, the movement between the upper rotating sleeve 32 and the lower rotating sleeve 31 can be restricted, so that the rotating lower rotating sleeve 31 can drive the upper rotating sleeve 32 to rotate, and through the insertion cavity 33 and the through hole 34, water can be sprayed onto the inner wall of the aquarium body 1, improving the cleaning effect of the inner wall of the aquarium body 1. When installing the recycling cylinder 53, first insert the recycling cylinder 53 into the movable seat 52, then press the two retaining rings 57 into the movable seat 52 through the movable rod 58. Subsequently, through the insertion connection between the first rotating seat 55 and the second rotating seat 56, rotate the movable seat 52 inward until it coincides with the fixed seat 51. Finally, release the second spring 59. Under the action of the second spring 59 restoring its deformation, it can drive the two retaining rings 57 to expand outward until they are inserted into the inner cavity of the fixed seat 51. Through the retaining rings 57, the connection between the first rotating seat 55 and the second rotating seat 56 can be positioned, and the connection between the two can be sealed, thereby completing the installation of the recycling cylinder 53. When water passes through the recycling cylinder 53, impurities in the water can be blocked through its internal filter screen 54. Conversely, the recycling cylinder 53 can be disassembled to recover the impurities filtered out by the water inside the recycling cylinder 53.

[0027] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0028] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
