In the accident state that the water filter pipe 4 is sealed and clamped by the water plug 6 and cannot open running water, the reason that water cannot overflow from the upper cylinder is as follows: the water and gas guiding large pipe 11 mainly has the main function of controlling the water in the fish tank 1 above not to exceed the highest height of the fish tank 1 above, the water and gas guiding large pipe 11 is lower so as to prevent the water from overflowing from the fish tank 1 above, if the water filter pipe 4 is sealed and clamped by the water blocking plug 6 and can not be opened, the water level of the fish tank 1 above is higher than the opening at the top end of the water and gas guiding large pipe 11, the water in the fish tank 1 above enters the water and gas guiding large pipe 11, flows into the water storage tank 2 below through the upper and lower tank double-through pipes 23 from the upper tank double-through hole 14 at the bottom of the water and gas guiding large pipe 11, the water level of the fish tank 1 above can never exceed the opening height of the fish tank 1 above, and the water in the fish tank 1 above can never overflow the fish tank 1. In the accident state, the height of the independent water levels of the upper cylinder and the lower cylinder is determined by the height of the water and air guide pipe 11.

In the accident state that the water plug 6 can not seal the water filter pipe 4 and leak water for a long time, the reason that water can not overflow in the lower cylinder is as follows: the lower sealed water storage tank 2 is a fully sealed container, each hole of the lower sealed water storage tank 2 is in a sealed state, four holes, namely a lower tank water filtering hole 15, a lower tank water lifting hole 17, a lower tank air guide hole 18 and a lower tank double-through hole 19, in five holes on the lower sealed water storage tank 2 are respectively sealed with the outer walls of four penetrating pipes, water cannot overflow from the holes to the pipes, and the maintenance operation hole 24 is sealed by a hole outer sealing cover plate 26 to be watertight. If the water blocking plug 6 can not seal the water filter pipe 4 to leak water for a long time, and when the water in the upper aquarium 1 flows into the lower sealed water storage tank 2 too much, the lower sealed water storage tank 2 discharges the water in the lower sealed water storage tank 2 upwards into the upper aquarium 1 through the upper and lower tank double-way pipes 23, so that the downward flowing water of the water filter pipe 4 and the upper and lower tank double-way pipes 23 discharge water upwards, the lower ornamental aquarium area 1-1 and the control aquarium area 1-2 of the longitudinal partition plate 7 are communicated, the downward flowing and the upward discharging finally enable the water to generate a balanced water level in the upper aquarium 1, the balanced water level is always lower than the water level of the upper aquarium 1 in a normal filtering state, and the water cannot overflow from the upper sealed water storage tank 1 and the lower sealed water storage tank 2. In the accident state, the lower sealed water storage tank 2 is filled with water, the combined water level of the upper tank and the lower tank is the water level of the upper aquarium 1, and the height of the combined water level is determined by the total water volume of the upper tank and the lower tank. When the accident that the water plugging plug 6 can not seal the water filter pipe 4 is removed, and the water plugging plug 6 can normally seal the water filter pipe 4, the water pump 21 is started to pump up the water in the lower sealed water storage tank 2 to the upper aquarium 1, the lower tank air inlet and outlet pipe 22 sucks air from the top end opening to enter the lower sealed water storage tank 2, so that the water in the lower sealed water storage tank 2 can be pumped away.

In the accident state that the water blocking plug 6 can not seal the water filtering pipe 4, without any assistance of mechanical action, the lower sealed water storage tank 2 drains air from the lower tank air inlet and outlet pipe 22 and the upper and lower tank double-way pipe 23, then water is filled in the lower sealed water storage tank 2, the upper aquarium 1 flows into the water of the lower sealed water storage tank 2 through the water filtering pipe 4, and then the water is discharged into the upper aquarium 1 from the upper and lower tank double-way pipe 23, the water filtering pipe 4 and the upper and lower tank double-way pipe 23 connect the upper and lower tanks into a combined tank system, wherein the water storage volume of the combined tank is larger than that of the normal liquid level of the upper and lower tanks which respectively store water independently during normal operation, the highest liquid level of the combined water of the upper and lower combined tanks can only be lower than the top opening height of the water guiding and air guiding pipe 11, so that the accident state that the water blocking plug 6 can not seal the water filtering pipe 4, without the assistance of any mechanical action, the upper and lower independent water storage tanks are combined into a combined tank through the upper and lower tank double-way pipe 23 to store water uniformly, and no water overflows.

Therefore, the most important invention points of the invention are as follows: in the accident state that the water blocking plug 6 can not seal the water filter pipe 4, the original states of independent water storage and independent liquid level height of the upper and lower cylinders are naturally changed into a combined water storage cylinder which is combined by the upper and lower cylinders into a unified water storage and water storage volume increasing and only one water storage liquid level in the upper aquarium 1 under the bidirectional flow action of the water filter pipe 4 and the upper and lower cylinder double-way pipe 23 without the assistance of any manual or automatic mechanical action, and the combined water storage cylinder is naturally combined by the upper and lower cylinders to form the circulating filtered water ornamental aquarium without water overflow, so that the problem that the water overflows from the upper and lower two-cylinder circulating filtered water ornamental aquarium when the water blocking plug 6 can not seal the water filter pipe 4 is thoroughly solved, and the upper and lower two-cylinder circulating filtered water ornamental aquarium can be popularized and applied in a wider market.

The utility model has the advantages that: in normal use state, the independent water level of the upper and lower cylinders is determined by the distance between the water floating block and the water blocking plug, and the two cylinders which are maintained by automatically circulating and filtering water in the upper and lower cylinders respectively have own water levels.

In the accident state that the water filter pipe is sealed and clamped by the water blocking plug and can not be opened, the height of the independent water levels of the upper tank and the lower tank is determined by the height of the water guide and air guide large pipe, and the upper end of the upper aquarium is higher than the opening at the upper end of the water guide and air guide large pipe, so that water does not overflow from the upper end of the upper aquarium.

In the water leakage accident state that the water blocking plug can not seal the water filter pipe, the lower sealed water storage tank is sealed and filled with water, the lower sealed water storage tank is sealed and does not have water overflow, due to the communication effect of the upper and lower tank double-way pipes, the combined water level of the upper and lower two tanks is the water level of the upper aquarium, the combined water level is determined by the total water amount of the upper and lower two tanks, the combined water storage body of the upper and lower two tanks is added, the space of the lower sealed water storage tank in the normal state is used for storing water, and therefore the upper and lower two tanks do not have water overflow.

In the normal use state and the accident state that the water plugging plug blocks the strainer pipe seal and can not be opened, the independent water storage of the upper and lower two tanks can not overflow water, and in the water leakage accident state that the water plugging plug can not seal the strainer pipe, the combined water storage volume of the upper and lower two tanks increases the space of the lower sealed water storage tank in the normal state for water storage, so that the upper and lower two tanks can not overflow water. In a word, the automatic pollution discharge circulating water filtering type ornamental fish tank does not overflow water in any state, and the water storage property is absolutely safe.

The problem that water overflows from the upper and lower two-cylinder type circulating filtering water ornamental fish tank when the water blocking plug cannot seal the water filtering pipe to leak water is thoroughly solved, so that the upper and lower two-cylinder type circulating filtering water ornamental fish tank can be widely popularized and applied to the market.
