Detailed Implementation

[0008] To more clearly illustrate the embodiments of this utility model or the technical solutions in the prior art, the drawings used in the embodiments will be briefly described below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without any creative effort.

[0009] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The embodiments cannot be described in detail here, but the embodiments of the present invention are not limited to the following embodiments.

[0010] Combination Figures 1-3 As shown, this utility model provides an automatic drainage device for maintaining the water level in a fish tank, including a device housing 1 and a device top cover 2 sealed to the device housing 1. The device housing 1 has a first drain outlet 11 on its lower side, an overflow pipe 12 with an overflow port 121 at its upper end, and a second drain outlet 122 extending beyond the device housing 1 at its lower end. The device top cover 2 has a mounting hole 21, and a first siphon pipe 3 is sealed to the mounting hole 21 and connected to the device housing 1. In this embodiment, the first siphon pipe 3 is a rigid transparent pipe, which can be sealed to the mounting hole 21 on the device top cover 2 using a rubber ring or other sealing methods.

[0011] According to one embodiment of this utility model, the top cover 2 of the device is further provided with a connecting structure 4, which has an installation inlet 41 and an installation outlet 42. The installation outlet 42 is located above the overflow port 121. A second siphon pipe 5 is connected to the installation outlet 42, and the end of the second siphon pipe 5 away from the device housing 1 is higher than the end of the first siphon pipe 4 away from the device housing 1. A first drain port 11 is connected to a first drain pipe 6, and a second drain port 122 is connected to a second drain pipe 7. The first drain pipe 6 is provided with a first control valve 61, and the second drain pipe 7 is provided with a second control valve 71.

[0012] The automatic drainage device for maintaining the water level in a fish tank of this utility model involves placing one end of the first siphon tube 3 into the water in the fish tank. The first siphon tube 3 allows the water level in the fish tank to be kept at the same height as the water level of the device. When water is added to the fish tank, the automatic drainage begins when the water level is higher than the overflow drain 121. When adding water stops, the drainage stops when the water level is equal to the overflow drain 121.

[0013] The second siphon tube 5 is inserted into the fish tank at a certain height above the water surface. When the water filling speed is normal, the water level will not be higher than the second siphon tube end. Air is drawn into the device, which is a non-sealed environment and is in an overflow state. When the water filling speed in the fish tank is too fast, the water level in the fish tank rises rapidly. When the water level exceeds the second siphon tube end and is higher than the installation outlet, the device becomes a sealed environment because the second siphon tube 5 end is blocked by water, forming a siphon phenomenon, which can achieve rapid drainage until the water level in the fish tank is lower than the second siphon tube end. Then, air is drawn into the device again, returning to a non-sealed environment and an overflow state.

[0014] When the device is working normally, the first control valve 61 is closed and the second control valve 71 is open. In long-term experimental practice, it was found that gas will be generated in the water and enter the first siphon tube, where it will accumulate at the highest point. The accumulation of gas will affect the water flow rate and, if it accumulates to a certain extent, will destroy the siphon effect, making the device unable to drain water normally. When gas accumulation is found, the water can be quickly drained by opening the first control valve 61, thereby removing the gas from the first siphon tube 3.

[0015] According to one embodiment of this utility model, the automatic drainage device for maintaining the water level in a fish tank includes an anti-detachment bracket 8 on the device housing 1, with a suction cup 81 mounted on the bracket 8. The anti-detachment bracket 8 has a wavy opening to hold the suction cup 81 in place. The top of the anti-detachment bracket 8 has a mounting hole for a second siphon tube 5, with hooks on both sides of the mounting hole. In this embodiment, the second siphon tube 5 is a soft plastic tube, with one end inserted into the mounting inlet 41 and the other end inserted into the mounting hole of the anti-detachment bracket 8. The suction cup 81 can be directly attached to the outer wall of the fish tank, making installation convenient. The anti-detachment bracket prevents the product from falling off if the suction cup fails, avoiding unnecessary losses.

[0016] This utility model relates to an automatic drainage device for maintaining the water level in aquariums. When aquariums require regular and quantitative water changes, this product can automatically change the water. Simply keep adding new water to the aquarium, and the product will use the siphon effect to keep the water level in the aquarium consistent with the water level on the device. When the water level exceeds the overflow outlet, it will automatically drain the water. Adjusting the installation height of the product can control the water level in the aquarium.

[0017] Through long-term experimental practice, it has been found that gas will be generated in the water and enter the first siphon tube, where it will accumulate at the highest point. The accumulation of gas will affect the water flow rate and, if it accumulates to a certain extent, will destroy the siphon effect, preventing the product from draining properly. When gas accumulation is found, the first control valve can be opened to quickly drain the water and remove the gas from the first siphon tube.

[0018] The above description is merely one embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
