DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model.

[0028] Please refer to Figures 1-4 , the present utility model provides a technical solution: an automatic feeding and water-changing fish tank, comprising: a fish tank body and an automatic water-changing structure.

[0029] The fish tank body includes a cylinder body 1 and a cylinder head 2 that can be covered with the cylinder body 1. The upper surface of the cylinder head 2 is provided with an automatic fish tank feeder 13. The automatic fish tank feeder 13 is a prior art and can be a commonly available automatic fish feeder on the market, which can automatically feed fish, so it will not be elaborated here.

[0030] The automatic water-changing structure is arranged on the left side of the cylinder body 1 and includes a filter box 3 fixedly installed on the left side surface of the cylinder body 1, and a filtering component and a water-changing component respectively arranged inside the filter box 3. The upper surface of the filter box 3 is covered with a cover plate 20, and the cover plate 20 can shield the filtering component and the water-changing component inside the filter box 3 to improve the aesthetics.

[0031] The filter component includes a partition plate 4 fixedly installed inside the filter box 3. The filter box 3 can be separated into a fish feces interception bin 5 and a bacteria cultivation bin 6 by the partition plate 4. A water return groove 17 is formed on the surface of the partition plate 4. The water return groove 17 is respectively communicated with the fish feces interception bin 5 and the bacteria cultivation bin 6. And a drain port 7 is formed on the inner bottom wall of the bacteria cultivation bin 6. One end of the drain port 7 extends into the interior of the cylinder body 1.

[0032] An inlet water component is arranged inside the fish feces interception bin 5. The inlet water component includes a water inlet pipe 14 fixedly installed on the inner wall of the fish feces interception bin 5. One end of the water inlet pipe 14 extends into the interior of the cylinder body 1 and a water pump 15 is fixedly installed. The other end of the water inlet pipe 14 is inserted with a diffusion pipe 16. A plurality of drain holes are equidistantly formed on the surface of the diffusion pipe 16. When the water pump 15 pumps water into the diffusion pipe 16, the diffusion pipe 16 will disperse and flow out the water flow.

[0033] A stop block 18 is fixedly installed on the inner wall of the fish feces interception bin 5. The upper surface of the stop block 18 is lapped with a filter mesh plate 19. Filter cotton can be placed on the filter mesh plate 19. When the water and impurities in the diffusion pipe 16 flow out, they will first enter the filter cotton. The filter cotton can intercept the impurities. The intercepted water will enter the bacteria cultivation bin 6 along the water return groove 17. After filter materials are placed in the bacteria cultivation bin 6, the filter materials will cultivate nitrifying bacteria. When the water flow contacts the nitrifying bacteria through the filter materials, the harmful substances in the water can be decomposed. Then the water will flow back into the cylinder body 1 along the drain port 7.

[0034] The water change component includes a drip pipe 8 and an L-shaped drain pipe 9 respectively fixedly installed on the back of the filter box 3, and an adjustment pipe 10 inserted into the inner wall of the L-shaped drain pipe 9. And flow regulating valves 11 are arranged on the surfaces of the drip pipe 8 and the L-shaped drain pipe 9. One ends of the drip pipe 8 and the L-shaped drain pipe 9 extend into the interior of the bacteria cultivation bin 6. And a sealing ring 12 is fixedly installed on the surface of the adjustment pipe 10.

[0035] Connect the L-shaped drain pipe 9 to the external sewage pipe, and connect the drip pipe 8 to the external faucet pipe. Then the flow rates of the drip pipe 8 and the L-shaped drain pipe 9 can be adjusted to be the same by using the flow regulating valve 11. At this time, the drip pipe 8 will slowly drip clean water into the bacteria cultivation bin 6. At the same time, the adjustment pipe 10 will discharge the water above the adjustment pipe 10 from the bacteria cultivation bin 6.

[0036] Since the drain port 7 is arranged in the bacteria cultivation bin 6, the water level in the bacteria cultivation bin 6 will be the same as the water level in the cylinder body 1. Pulling the adjustment pipe 10 can make the adjustment pipe 10 slide along the inner wall of the L-shaped drain pipe 9. The sealing ring 12 can prevent water from discharging along the connection gap between the adjustment pipe 10 and the L-shaped drain pipe 9. Thus, the height of the adjustment pipe 10 can be changed according to the water level in the cylinder body 1 to make it adapt to the cylinder body 1 with different water levels.

[0037] Compared with the prior art, the device adopts a drip tube 8 to continuously drip a small amount of clean water into the cylinder body 1, so that the cylinder body 1 continuously has a clean water source. At the same time, the regulating tube 10 can overflow and discharge the excess water above the regulating tube 10 to realize automatic water change. And when the evaporation rate of the water in the cylinder body 1 is greater than the dripping rate, at this time, the water level in the cylinder body 1 will be lower than the regulating tube 10, and then the drip tube 8 will supplement water, so as to ensure that the water level in the cylinder body 1 remains unchanged and avoid the problem of fish death caused by water shortage in the cylinder body 1.

[0038] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any equivalent replacement or change made by those skilled in the art according to the technical solution and concept of the present invention should be covered within the protection scope of the present invention.
