Description

Technical Field

[0001] This utility model relates to the field of aquarium technology, and in particular to a self-circulating filter desktop aquarium without pipes. Background Technology

[0002] Aquariums, as water tanks for raising fish, are usually transparent glass tanks used to keep tropical fish or goldfish for ornamental purposes, and are therefore popular. In order to improve the survival rate of the fish, a filtration and circulation system is usually installed in the aquarium. The filtration and circulation system requires the installation of pipes in the aquarium to transport water. The pipes will affect the aesthetics of the aquarium and may block the view of people watching the fish at certain angles. To solve this problem, some pipeless aquariums have appeared on the market.

[0003] For example, the Chinese utility model patent CN222148706U, entitled "A Novel Fish Tank Without Pipe Fittings Inside the Tank", includes a fish tank body and at least one set of cleaning and drainage components. The cleaning and drainage components are installed on the outer wall of the fish tank body. The cleaning and drainage components include a drain pipe and an overflow cover. The overflow cover is fixedly installed on one side of the fish tank body, so that an overflow space with a top opening and a sealed perimeter is formed between the overflow cover and the fish tank body. The side wall of the fish tank body has an upper drain port and a lower drain port that communicate with the overflow space in the vertical direction. One end of the drain pipe is connected to the lower drain port, and the other end is set at a position lower than the upper drain port. The bottom of the overflow cover is connected to a drain pipe, and the other end of the drain pipe is connected to a filter box.

[0004] In the above scheme, water in the aquarium can only overflow from the drain pipe and enter the filter box for filtration when the water level in the aquarium rises to the top of the drain pipe. When the water in the filter box has completely entered the aquarium, the water level in the aquarium is still lower than the top of the drain pipe, so the water in the aquarium cannot be filtered. When people are away from home for a long time, the fish may die from lack of oxygen. Utility Model Content

[0005] This invention addresses the problem that when water is completely inside the aquarium and the water level in the aquarium is still below the top of the drain pipe, the water in the aquarium cannot be filtered. The technical problem this invention aims to solve is to provide a self-circulating, pipe-free desktop aquarium with filtration.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a self-circulating filter desktop fish tank without pipes, including a transparent main tank and a bottom filter tank fixedly integrated with the main tank below the main tank. The bottom filter tank is provided with a filtration zone and a clean water zone communicating with the bottom of the filtration zone. A filtration device is provided in the filtration zone. A drain pipe extending upwards to the bottom of the main tank to connect the filtration zone and the main tank is provided in the filtration zone.

[0027] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0028] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0029] This embodiment mainly describes a self-circulating filter desktop fish tank without tubing, as detailed below:

[0030] like Figures 1 to 5As shown, a self-circulating, filtration-based desktop aquarium without pipes includes a main tank 1 and a bottom filter tank 2. The main tank 1 is used to raise fish or other aquatic organisms, while the filter tank is used to filter fish waste and debris in the main tank 1 to improve water quality. For aesthetic purposes, both the main tank 1 and the bottom filter tank are made of transparent material. The bottom filter tank 2 is fixedly installed below the main tank 1, forming an integrated structure. The bottom filter tank 2 contains a filtration zone 21 and a clean water zone 22 connected to the bottom of the filtration zone 21. The filtration zone 21 contains a filter device 3 and a drain pipe 4 extending upwards to the bottom of the main tank 1, connecting the filtration zone 21 to the main tank 1. The lower end of the drain pipe 4 is located above the filter device 3 and is used to transport water from the main tank 1 to the filtration zone 21 for filtration. The clean water zone 22 contains a drain pipe extending upwards to the bottom of the main tank 1, connecting the clean water zone 22 to the main tank 1. The water inlet pipe 5 is used to transport filtered water into the inlet area to the main tank 1. The clean water area 22 is equipped with a water pump 221 connected to the lower end of the water inlet pipe 5 to transport water from the clean water area 22 to the main tank 1 via the water inlet pipe 5. The water outlet pipe 4 is equipped with a float valve 6 located in the clean water area 22 and controls the opening or closing of the water outlet pipe according to the water level in the clean water area 22. When fish are being raised in the main tank 1, the water in the main tank 1 enters the filter area 21 through the water outlet pipe 4 and flows into the clean water area 22 after filtration. When the water level in the clean water area 22 reaches the preset value, the float valve 6 controls the water outlet pipe to close, and the water outlet pipe stops flowing water into the filter area 21. At this time, the water pump 221 works, and the water in the clean water area 22 flows into the main tank 1 through the water inlet pipe 5. When the water inlet pipe 5 causes the water level in the clean water area 22 to drop below the preset value, the float valve 6 controls the water outlet pipe to open, and the water outlet pipe flows water into the filter area 21, and so on. In this invention, water in the main tank 1 enters directly from the bottom of the main tank 1 through the drain pipe 4. The opening and closing of the outlet pipe is controlled by the float valve 6, realizing automatic circulation filtration between the main tank 1 and the bottom filter tank 2. As long as there is water in the main tank 1, the filtration circulation between the main tank 1 and the bottom filter tank 2 is always in progress. There is no need to worry about the water in the main tank 1 evaporating below a certain level due to prolonged absence, resulting in the inability to filter and purify the water, causing the fish to die from lack of oxygen or poisoning. Furthermore, both the inlet pipe 5 and the outlet pipe 4 are connected to the filter tank from the bottom of the main tank 1, ensuring that there are no pipes inside the main tank 1, thus not obstructing the user's view of the fish and enhancing the ornamental value of the aquarium.

[0031] Specifically, the filtration zone 21 includes a backflow zone 211 and a drip zone 212. The filter device 3 is located in the drip zone 212, and the lower end of the drain pipe 4 is located in the backflow zone 211. The backflow zone 211 is used to settle fish feces and residue carried in the water to reduce the filtration pressure of the filter device 3 in the drip zone 212. To reduce the noise when the drain pipe 4 drains water, the lower end of the drain pipe 4 is located below the liquid surface of the backflow zone 211, preferably below the middle of the backflow zone 211. A top overflow port 7 is provided between the backflow zone 211 and the drip zone 212 so that the water in the backflow zone 211 enters the filtration zone 21 through the top overflow port 7. In order to improve the filtration effect, the top overflow port 7 is higher than the filter device 3 to ensure that the water flows into the filter device 3 from above.

[0032] Specifically, the filtration device 3 includes a wet-dry separation box 31 and a trickle filter media box 32. The wet-dry separation box 31 contains filter cotton, which intercepts fish waste and residue. Multiple trickle filter media boxes 32 can be set and stacked. Each trickle filter media box 32 contains several filter media layers, which can adsorb and decompose harmful substances in the water. Each layer is in full contact with the air, increasing the dissolved oxygen in the water. To delay water acidification, increase water oxygen content, and prevent the filter cotton from being soaked in the water for a long time, which would cause organic impurities to decompose and pollute the water, the wet-dry separation box 31 is located above the trickle filter media box 32. A guide plate 9 is fixedly installed in the trickle area 212. The guide plate 9 has several evenly distributed guide holes. Both the wet-dry separation box 31 and the trickle filter media box 32 are located below the guide plate 9. The guide plate 9 disperses the water in all directions, avoiding localized high filtration pressure that would affect the filtration effect.

[0033] Specifically, a bottom overflow port 8 is provided between the dripping zone 212 and the clean water zone 22 to connect the bottom of the dripping zone 212 and the clean water zone 22. After the water in the backflow zone 211 is separated into dry and wet parts and filtered by the bottom filter media, it flows into the bottom of the dripping zone 212 and into the clean water zone 22 through the bottom overflow port 8. The bottom overflow port 8 is located at the bottom to enhance the flow of water at the bottom of the dripping zone 212 and prevent stagnant water from forming, which would affect the water quality in the tank.

[0034] Specifically, the drain pipe 4 includes a first pipe body 41, a second pipe body 42, and a third pipe body 43 located inside the bottom filter tank 2. One end of the first pipe body 41 has a drain connector 44 that penetrates the bottom of the main tank 1, and the other end extends from one side of the bottom of the main tank 1 toward the clean water zone 22. One end of the second pipe body 42 is located in the clean water zone 22, and the other end extends from the clean water zone 22 toward the filter zone 21. The float valve 6 has two connection ports, one of which is connected to the end of the first pipe body 41 located in the clean water zone 22, and the other connection port is connected to the end of the second pipe body 42 located in the clean water zone 22. The third pipe body 43 is connected to the end of the second pipe body 42 away from the float valve 6 and is perpendicular to the second pipe body 42, and the lower end of the third pipe body 43 is located below the liquid surface of the backflow zone 211.

[0035] Specifically, in order to prevent water in the main cylinder 1 from flowing back into the clean water area 22, a check valve 51 is provided on the water supply pipe 5 to prevent water in the main cylinder 1 from flowing back. The upper end of the water supply pipe 5 has a water supply connector 52 that penetrates the bottom of the main cylinder 1. Water in the water supply pipe 5 enters the main cylinder 1 from the water supply connector 52.

[0036] Specifically, when changing the water in the fish tank, the water in the main tank 1 and the bottom filter tank 2 needs to be drained. To facilitate drainage, the water inlet pipe 5 is equipped with a drain pipe 10 that is perpendicular to and connected to the water inlet pipe 5. The drain pipe 10 is equipped with a drain valve 101. When the drain valve 101 is opened, the water pump 221 discharges the water in the clean water area 22 from the drain pipe 10. When the drain valve 101 is closed, the water inlet pipe 5 fills the main tank 1 with water.

[0037] Specifically, the check valve 51 is located on the lower side of the connection between the water inlet pipe 5 and the drain pipe 10. The position of the check valve 51 is designed to prevent water from flowing back into the main cylinder 1 when water is supplied from the water inlet pipe 5, and also to prevent water from flowing back into the drain pipe 10 when water is drained.

[0038] Specifically, the upper ends of the water inlet pipe 5 and the lower ends of the water outlet pipe 4 are located opposite each other on both sides of the main tank 1. The outlet of the water inlet connector 52 and the inlet of the drain connector 44 are opposite each other. When the water inlet pipe 5 feeds water into the main tank 1, the water inlet connector 52 can blow up the fish waste and residue at the bottom of the main tank 1 under the power of the water pump 221 and discharge them from the opposite drain connector. The fish waste and residue in the main tank 1 can be automatically cleaned by the water flow, which is simple and convenient.
