[0020] 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.

[0021] It should be noted that like reference numerals denote like items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0022] This embodiment mainly describes a fish tank that can automatically change water, as follows:

[0023] like Figure 1-4As shown, the fish tank with automatic water change includes a fish farming area 1, a clean water area 2 and a sewage area 3. The fish farming area 1 is used for fish farming, the clean water area 2 is used to provide a clean water source for the fish farming area 1, and the pollution area is used to collect and treat the sewage discharged from the fish farming area 1. The fish farming area 1 is connected to the clean water area 2 through a first pipe 4, the fish farming area 1 is connected to the sewage area 3 through a second pipe 5, and the clean water area 2 is connected to the sewage area 3 through a third pipe 6. A speed regulating pump 7 is provided on the first pipe 4. The speed regulating pump 7 is mainly used to control the flow rate of the clean water in the first pipe 4 flowing into the fish farming area 1. The speed regulating pump 7 is preferably a peristaltic pump. The first pipe 4, the clean water area 2, the third pipe 6, the sewage area 3 and the second pipe 5 form a water inlet channel. Except for the water outlet and water inlet at both ends, the rest of the structure is a sealed structure, and the water outlet of the water inlet channel is submerged below the water body of the fish farming area 1. When changing the water, the peristaltic pump is started, and the water in the clean water bottle 21 flows into the fish farming area 1 through the first pipe 4. The sewage area 3 forms a negative pressure with the fish farming area 1, and the same amount of water in the fish farming area 1 is pumped out into the sewage area 3. The air in the sewage area 3 circulates into the clean water area 2, and the air pressure in the clean water area 2 increases to transport the water in the clean water area 2 to the fish farming area 1. This cycle is repeated continuously. The speed of replacing the water in the fish farming area 1 can be controlled by controlling the flow rate of the flow pump. If you are away from home for a long time, you can adjust the flow rate pump and the fish tank can change the water automatically to avoid the fish from dying of lack of oxygen due to being away from home for a long time.

[0024] Specifically, one end of the second pipe 5 extends into the sewage area 3, and the other end extends into the fish farming area 1, preferably the other end extends into the bottom of the fish farming area 1. When the water in the fish tank is changed, the sewage at the bottom of the fish farming area 1 can be replaced for a long time to avoid the sewage at the bottom of the fish farming area 1 not being discharged properly, resulting in long-term accumulation of residues, which affects the quality of the water in the fish farming area 1.

[0025] like Figure 4 As shown, a water level sensor 8 is provided in the sewage area 3, and the speed regulating pump 7 has a control part for adjusting and controlling the speed regulating pump 7. The control part is a control panel connected to a power supply. The water level sensor 8 is connected to the control panel. When the water level sensor 8 detects that the water level in the sewage area 3 reaches a preset height, it sends a signal to the control part of the speed regulating pump 7 to control the speed regulating pump 7 to stop working, so as to prevent the clean water in the clean water area 2 from continuing to be transported to the fish farming area 1, and the sewage in the fish farming area 1 from continuing to be transported to the sewage area 3, so that the sewage in the sewage area 3 is too full and flows into the clean water area 2 from the third pipe 6, resulting in the pollution of the clean water cup and sewage in the clean water area 2.

[0026] Specifically, one end of the first pipe 4 extends into the bottom of the water purification area 2, and the other end extends into the inside of the fish farming area 1. Since the first pipe 4 penetrates into the bottom of the water purification area 2, the water at the bottom of the water purification area 2 can flow into the fish farming area 1 under the action of air pressure. When the water in the water purification area 2 is low, there is no need to worry about the problem of being unable to change the water due to the low water in the water purification area 2.

[0027] Specifically, the fish farming area 1 is a transparent cylinder, the sewage area 3 is a sealed sewage bottle 31 arranged outside the transparent cylinder, and the water purification area 2 is a sealed water purification bottle 21 arranged outside the transparent cylinder. The fish farming area 1, the water purification area 2 and the sewage area 3 can also be an integrally formed cylinder, and the water purification area 2 and the sewage area 3 are sealed by partitions and cover plates, and the above-mentioned water inlet channels are set in the fish farming area 1, the sewage area 3 and the water purification area 2.

[0028] Specifically, the sewage bottle 31 is provided with a drainage channel 32 extending out of the sewage bottle 31, and the drainage channel 32 is provided with a water outlet valve 33. The sewage channel is used to discharge the sewage in the sewage bottle 31. The sewage channel is provided at the bottom of the sewage bottle 31, which can completely drain the sewage in the sewage bottle 31, thereby avoiding the problem of the sewage in the sewage bottle 31 being completely discharged. The clean water bottle 21 is provided with a water inlet channel (not shown) extending out of the clean water bottle 21, and the water inlet valve (not shown) is provided on the water inlet channel (not shown). The water inlet channel (not shown) is connected to a water source. When the clean water in the clean water bottle 21 is used up, the water inlet valve (not shown) can be opened to add water to the clean water bottle 21.

[0029] During operation, the flow pump is started, and the water in the clean water area 2 flows into the fish farming area 1. The sewage area 3 forms a negative pressure with the fish farming area 1, and the water in the fish farming area 1 is pumped into the sewage area 3. Due to the entry of sewage, the gas in the sewage area 3 enters the clean water area 2 through the third pipe 6, and the water in the clean water area 2 enters the fish farming area 1 again through the flow pump, thus continuously circulating. When the water level in the sewage bottle 31 reaches a preset height, the water level sensor 8 sends a signal to the speed regulating pump 7 control panel to control the speed regulating pump 7 to stop working.
