It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] like Figures 1 to 3 As shown, the utility model provides an automatic ventilation device 1 for a sealed fish tank, including a cylinder body 2, the cylinder body 2 is a sealed cylinder body 2, and the top of the sealed cylinder body 2 is provided with an opening for adding or removing water or adding or removing fish. During transportation and daily fish farming, the opening at the top of the cylinder body 2 is closed, and the cylinder body 2 is provided with an external ventilation hole 21, including at least one automatic ventilation device 1, one automatic ventilation device 1 connects the air outside the cylinder body 2 with the air inside, one automatic ventilation device 1 includes a float 11, a hollow hose 12 and a connecting component 13, the connecting component 13 is arranged on the external ventilation hole 21, the connecting component 13 connects the external ventilation hole 21 with the hollow hose 12, and the float 11 and the hollow hose 12 are both provided On the inner side of the cylinder body 2, a circular groove is provided in the middle position of the upper end surface of the float, one end of the hollow hose 12 is provided with an inner air hole 121, the other end of the hollow hose 12 is connected to the connecting component 13, the other end of the hollow hose 12 passes through the float 11 and the inner air hole 121 is penetrated in the circular groove, the float 11 is made of foam, foam-like lightweight material or hollow material, the float 11 made of foam, foam-like lightweight material or hollow material floats on the water surface and is waterproof at the same time, the inner air hole 121 in the circular groove of the float 11 remains at the upper end of the water surface without water entering, the height of the inner air hole 121 is higher than the water level in the cylinder body 2, ensuring the air inside the cylinder body 2 and the air outside the cylinder body 2 to circulate.

[0022] Preferably, the other end of the hollow hose 12 passes through the float 11 and the inner air hole 121 is exposed from the float 11 and is arranged at the uppermost part of the float 11, and the inner air hole 121 is kept at the upper end of the water surface and does not get water.

[0023] Preferably, a plurality of the automatic ventilation devices 1 are included, and the plurality of the automatic ventilation devices 1 include a plurality of the automatic ventilation devices 1. The plurality of automatic ventilation devices 1 allow for better circulation between the outer air and the inner air of the cylinder body 2. When one of the plurality of automatic ventilation devices 1 is damaged or blocked, the damaged or blocked automatic ventilation device 1 stops automatic ventilation of the cylinder body 2, and the automatic ventilation device 1 in normal working state continues to connect the outer air and the inner air of the cylinder body 2. The arrangement of the plurality of automatic ventilation devices 1 ensures the connection between the outer air and the inner air of the cylinder body 2, and ensures effective and continuous circulation of gas inside and outside the cylinder body 2.

[0024] Preferably, the float 11 is made of foam, foam-like lightweight material or hollow material. The float 11 made of foam, foam-like lightweight material or hollow material floats on the water surface and is waterproof. The buoyancy of the float 11 can make the inner air hole 121 of the hollow hose 12 float and remain above the water surface. The inner air hole 121 in the circular groove of the float 11 remains at the upper end of the water surface without water entering. The height of the inner air hole 121 is higher than the water level in the cylinder body 2, thereby ensuring the air inside the cylinder body 2 and the air outside the cylinder body 2 to circulate.

[0025] Preferably, the float 11 is in an inverted cone or a quasi-inverted cone. When the position of the cylinder 1 changes, the water position changes. The head of the inverted cone or quasi-inverted cone-shaped float 11 is large and the water resistance is large. Under the effect of the water resistance, the inverted cone or quasi-inverted cone-shaped float 11 makes the inner air hole 121 of the hollow hose 12 move downward or sideways upward, effectively preventing water from flowing back into the inner air hole 121 of the hollow hose 12 when the position of the cylinder 1 changes. When the position of the hollow hose 12 changes in the water, due to the effect of the surface tension of the water body, the movement position of the inner air hole 121 of the hollow hose 12 prevents water from entering the hollow hose 12. When the cylinder 2 is transported, the water surface changes, and the float 11 can continue to float on the water surface, keeping the inner air hole 121 higher than the upper end of the water surface of the cylinder 2 without water entering.

[0026] Preferably, a clamping piece is included, one end of which is clamped to the cylinder 2, and the other end of which is clamped to the middle of the hollow hose 12. The hollow hose 12 is easily hit by the fish swimming in the cylinder 2, or the hollow hose 12 is easily shaken and changed in shape when the water flows. The clamping piece is clamped to the middle of the hollow hose 12, and the clamping piece fixes the hollow hose 12, further ensuring the stability of the automatic ventilation device 1, and ensuring the air inside the cylinder 2 and the air outside the cylinder 2 are circulated. The length of the hollow hose 12 from the position of the clamping piece to the water surface satisfies that the float 11 always floats on the water surface.

[0027] Preferably, the connecting component 13 includes a connecting piece 131 and a connecting joint 132 , one end of the connecting piece 131 is connected to the outer vent hole 21 , and the other end of the connecting piece 131 is connected to the connecting joint 132 , and the connecting joint 132 is connected to the hollow hose 12 .

[0028] Preferably, a sealing member is provided between the connecting member 131 and the external air hole 21, and the sealing member seals the connecting member 131 and the external air hole 21 to prevent air from leaking, thereby improving the sealing performance.

[0029] Preferably, it also includes an air pressure detection component, which is provided with the upper end of the water surface in the cylinder body 2. The air pressure detection component checks and displays the air pressure in the cylinder body 2. When the air inside and outside the cylinder body 2 are in a connected state, the air pressure detection component detects the air pressure in the cylinder body 2. At this time, the air pressure value is within a normal range, and the air pressure detection device displays that the air pressure in the cylinder body 2 is normal; when the automatic ventilation device 1 is damaged or blocked, the air inside and outside the cylinder body 2 are not connected, and the air pressure detection component detects that the air pressure value in the cylinder body 2 is not within a normal range. At this time, it reminds that the air pressure in the cylinder body 2 is abnormal, and the automatic ventilation device 1 needs to be checked and repaired or replaced to ensure the air inside the cylinder body 2 and the air outside the cylinder body 2 can circulate.

[0030] Preferably, the hollow hose 12 is made of PVC (Polyvinyl chloride), silicone, PA (Polyamide) or other plastics. The softness of the hollow hose 12 is sufficient to follow the movement of the float 12. Due to the surface tension of water, the smaller the diameter of the hollow hose 12, the less likely it is to get water when the float 12 changes its position in the water.

[0031] Preferably, the outer air vent 21 is disposed at the bottom, side or top of the cylinder body 2 .
