Description

Technical Field

[0001] This invention relates to the field of automatic cleaning aquarium technology, specifically a novel aquarium capable of automatic cleaning. Background Technology

[0002] A fish tank is a water vessel used to hold live fish. The tank body is transparent and mostly made of glass. It can also be used to raise tropical fish or goldfish for ornamental purposes. A fish tank is not only a home for fish, but also a shared living space for the family. The flawless double-layer float glass not only creates a warm home for the fish, but also ensures the safety of the overall living environment. However, the only drawback is that it cannot be fitted with a filtration system because the tank body is too thin. With the popularization of fish tanks, fish tanks with automatic cleaning functions have also emerged.

[0003] However, most of the existing self-cleaning aquariums use circulating water filtration for cleaning. This structure is convenient for automatic cleaning, but after long-term use, stains will accumulate on the surface of the aquarium glass, requiring manual cleaning. If not cleaned in time, bacteria will grow, harming or even killing the fish. Furthermore, larger aquariums are very inconvenient to clean and are prone to accidents that could cause the aquarium to break. Summary of the Invention

The clamping magnets 217 at the top of the outer clamping frame 202 and the inner clamping frame 209 are all opposite each other.

[0044] A wastewater filtration mechanism 3 is attached to the bottom of the glass fish tank cover 1;

[0045] The wastewater filtration mechanism 3 includes a support base 301, a partition frame 302, a drain rod 303, a square chamber 304, a collection pipe 305, a water filling box 306, a drain pipe 307, an impurity winding box 308, a filter box 309, a winding brush 310, a protein cotton filter screen 311, a clean water box 312, an ultraviolet germicidal lamp 313, a water pump 314, a water pump 315, a drain pipe 316, and a parallel pipe 317.

[0046] To thoroughly clean and filter the water inside the aquarium, a support base 301 is glued to the bottom of the glass aquarium cover 1. A partition frame 302 is welded to the top surface of the support base 301. Several drain rods 303 are embedded in the top of the support base 301 on the outside of the partition frame 302. The inside of the drain rods 303 is hollow, and several holes are opened on the outside of the drain rods 303. The diameter of the drain rods 303 is the same as the diameter of the inside of the mounting groove 214. The vertical installation position and number of the drain rods 303 are the same as the vertical installation position and number of the mounting groove 214. A square chamber 304 is welded to the bottom of the drain rods 303 on the inside of the support base 301. Four collecting pipes 305 are connected through the inside of the square chamber 304. The water outlet of the four collecting pipes 305 is connected to a water filling box 306. The bottom of the water filling box 306 is connected to a drain pipe 307.

[0047] To achieve water recycling, an impurity winding box 308 is welded to the inner side of the support base 301 at the outlet end of the drain pipe 307. A filter box 309 is welded to the outer surface of one end of the impurity winding box 308. The inner side of the support base 301 is hollow, and several holes are provided at the connection between the impurity winding box 308 and the filter box 309. The impurity winding box 308 and the filter box 309 are the same size and shape. A winding brush 310 is slidably embedded inside the impurity winding box 308, and a protein cotton filter screen 311 is slidably embedded inside the filter box 309. A parallel pipe 317 is connected through one end of the filter box 309, and a clean water box 312 is connected to the outlet end of the parallel pipe 317. A purple [unclear text - possibly a type of filter screen] is installed inside the clean water box 312. An ultraviolet germicidal lamp 313 and a water tank 312 are connected by a water pump 314 at the top. A water pump 315 is installed at the bottom inner side of the support base 301. The water filling box 306 is circular in shape. The outlet of the water pump 314 is connected to the inlet of the water pump 315. Several holes are opened at the top of the partition frame 302. The outlet of the water pump 315 is connected to a drain pipe 316. The outlet of the drain pipe 316 extends through the support base 301 to the top inner side of the oxygen-generating water circulation box 218. The power input terminals of the crawling motor 208, the ultraviolet germicidal lamp 313, and the water pump 315 are all connected to the power output terminal of an external control terminal. The signal input terminal of the crawling motor 208 is connected to a motor controller.

[0048] The working principle and usage process of this invention are as follows: First, the operator needs to place the fish into the aquarium. Then, the ultraviolet sterilizer 313 and water pump 315 are turned on. As the water pump 315 continues to pump, the water inside the glass aquarium cover 1 is sucked into the square compartment 304 through the holes on the outside of several drain rods 303. Then, it enters the water filling box 306 through the collection pipe 305, and then enters the impurity winding box 308 through the drain pipe 307. At that time, large impurities in the water will be wound and removed by the winding brush 310 inside the impurity winding box 308. Then, the water will continue to be sucked into the filter box 309 and filtered by the protein cotton filter screen inside the filter box 309. Ammonia nitrogen filtration is performed at 311 to prevent irreversible pollution of the water by fish feces. Then, water pump 315 will pump the water inside the filter box 309 into the clear water box 312 through parallel pipe 317. The ultraviolet sterilization lamp 313 inside the clear water box 312 can sterilize and remove algae from the water entering the clear water box 312, ensuring the cleanliness of the water. Finally, the clean water will be discharged through the drain pipe 316 at the outlet of water pump 315, and the clean water will be discharged into the oxygenated water circulation box 218. As the oxygenated water circulation box 218 disperses the water into the glass fish tank cover 1, it can generate oxygen while circulating water, which can increase the oxygen content in the water and ensure the survival of fish.

[0049] After a period of use, the crawling motor 208 is started. The motor controller connected to the signal input terminal of the crawling motor 208 can control the crawling motor 208 to rotate intermittently in both directions. At that time, the crawling motor 208 will drive the two pulleys 206 to rotate via the belt 207. At that time, the rotating rod 203 located at one end of the two pulleys 206 will also rotate. Then, the suction cup rod 205 on the outside of the fixing plate 204 sleeved on the outer surface of the rotating rod 203 will be attracted to the outer surface of the glass aquarium cover 1. As the fixing plate 204 rotates, the rotating rod 203 will drive the outer clamping frame 202 to move up and down. During this time, the outer clamping frame 202 will drive the inner clamping frame 209 to move together via the clamping magnet 217 at the top. During the movement, the shovels 210 located at the top and bottom of the inner clamping frame 209 will clean the dirt on the inner surface of the glass aquarium cover 1. The removed dirt enters the collection tank 212 through the connecting hole 213 inside the dirt inlet 210. During this process, the one-way plate 211 at the feed end of the dirt inlet 210 prevents the dirt inside the collection tank 212 from flowing out. As the inner clamping frame 209 slides past the top of the glass aquarium cover 1 and then slides towards the bottom of the glass aquarium cover 1, after the inner clamping frame 209 slides to the bottom of the glass aquarium cover 1, several drain rods 303 will be embedded into the collection tank 212 through the locking groove 214. As the drain rods 303 go deeper, they will push up the one-way cover 216 of the collection tank and go deeper into the inside of the collection tank 212. At that time, the holes on the outside of the drain rods 303 will pump the dirt and water inside the collection tank 212 into the square chamber 304, and then perform filtration and circulation. This can avoid manual cleaning of the aquarium and ensure the practicality and convenience of the aquarium.
