Optionally, a certain spherical or granular floatable filter material may be filled in the tank body 135 of the negative pressure tank 130, so that the filter material rolls along with water flow in the negative pressure tank 130, and the bacteria culturing efficiency is improved.
It is easy to understand that more negative pressure tanks 130 for closing the vent pipe ports can be additionally arranged in the first siphon pipeline 110, the second siphon pipeline 150 or the water pump 105 pipeline, so that more bacteria culturing areas can be arranged in the pipeline, and the filtering effect is enhanced. Of course, if the negative pressure tank 130 is disposed below the water-sealed tank 172, the third air-vent port 133 may be opened, so that the water flow may bring a large amount of air into the negative pressure tank 130 through the third air-vent port 133, further enhancing the bacteria culturing efficiency.
Fig. 7 is a schematic diagram of a fifth structure of a negative pressure siphon system 100 according to an embodiment of the present invention, and fig. 8 is a schematic diagram of an aerator 180 of the negative pressure siphon system 100 according to an embodiment of the present invention, please refer to fig. 7 and 8.
Negative pressure siphon system 100 may further include an aerator 180, where aerator 180 includes a third water inlet end 181, a silencing cover 183, and a third extension pipe joint 1811, where silencing cover 183 is a hollow structure with two open ends, and one end of silencing cover 183 is connected to third water inlet end 181, and the other end is open. The third sealing ring 187 is arranged at the joint of the silencing cover 183 and the third water inlet end 181 and is used for enhancing the sealing performance of the joint. The muffler 183 can reduce noise generated when the water flowing out from the water inlet or the water outlet hits the water surface. The third water inlet end 181 is provided with a third water inlet pipe interface 1813, a third extension pipe interface 1811 interface and a vent hole 1815, one end of the third extension pipe interface 1811 is connected to the third extension pipe interface 1811, and the other end is close to the open end of the silencing cover 183. The number of the aerator 180 may be one or more, and is not particularly limited herein, if the aerator 180 is disposed at any position of the first siphon line 110 or the second siphon line 150, for example, at the first water suction port 111, the first water discharge port 113, the second water suction port 151, the second water discharge port 153, or the water pump 105. The water flow will take air into the water in the aquarium 101 through the air holes 1815 to increase the oxygen content of the water.
Optionally, in order to eliminate noise generated when the second water suction port 151 absorbs water, the aerator 180 may be installed at the second water suction port 151, and when the water level floods the lower opening of the silencing cover 183, a semi-closed space is formed inside the second water suction port 151, so that noise generated when the second water suction port 151 absorbs water can be effectively reduced, and air in the semi-closed space can be sucked into the pipeline and brought into the filter cylinder 103 through water flow.
The first siphon line 110 is provided with a first valve 115, the second siphon line 150 is provided with a second valve 155, as long as the position of the first valve 115 is lower than the position of the siphon trigger device 120, the position of the first valve 115 is set at any position below the siphon trigger device 120, the negative pressure tank 130 is set at any position in the second siphon line 150, the water seal tank 172 is set at any position below the negative pressure tank 130, and the second valve 155 is set at any position below the negative pressure tank 130, which is not particularly limited herein. The first valve 115 and the second valve 155 may be used to manually adjust and control the amount of water discharged to thereby adjust the water level of the aquarium 101.
The negative pressure siphon system 100 provided by the invention has the following working principle:
in the first siphon line 110, since the water outlet of the first extension pipe 127 is close to the closed end of the overflow pipe 126 and is lower than the third opening 1261 of the overflow pipe 126, when the water in the fish tank 101 is introduced into the overflow pipe 126, the water in the overflow pipe 126 floods the lower opening of the first extension pipe 127, and the water in the fish tank 101 and the water in the overflow pipe 126 are communicated through the line. If the water level in the aquarium 101 is higher than the water level in the overflow pipe 126, the water in the aquarium 101 flows into the overflow pipe 126 through the pipe due to the height difference between the two containers, and the water in the overflow pipe 126 overflows again and flows into the filter bowl 103 through the pipe. When the water pump 105 is not operated, the water level in the fish tank 101 gradually drops to a level flush with the third opening 1261 of the overflow pipe 126, and when there is no level difference between the water level in the fish tank 101 and the water level in the overflow pipe 126, the water stops flowing from the fish tank 101 to the overflow pipe 126 and the water discharge is stopped. After the water pump 105 is started, water in the filtering tank 103 is conveyed into the fish tank 101, along with the rising of the water level of the fish tank 101, the water in the fish tank 101 continuously flows into the filtering tank 103 through the first siphon pipeline 110, and if the water inflow into the fish tank 101 is larger than the water drainage amount, the water level in the fish tank 101 continuously rises until the second water suction port 151 is submerged. At this time, because the second drain port 153 is also submerged in water or a closed channel is formed in the second siphon channel 150, air cannot enter the second siphon channel 150 and the siphon trigger apparatus 120. Because the siphon trigger device 120 and the negative pressure tank 130 are communicated through the breather pipe 160, the water flowing in the first siphon pipeline 110 continuously draws out the air in the second siphon pipeline 150 and the siphon trigger device 120, so that the negative pressure value in the pipeline becomes higher and higher, and suction force is generated when the negative pressure value reaches a certain value, so that the suction force of the first water suction port 111 is increased, more water is sucked into the first siphon pipeline 110, a first siphon connection between the fish tank 101 and the filter cylinder 103 is established, and the water discharge is increased instantaneously. At this time, the water flowing fast in the first siphon pipeline 110 evacuates the air remaining in the second siphon pipeline 150 rapidly, further increases the negative pressure value in the second siphon pipeline 150, introduces the water in the fish tank 101 into the second siphon pipeline 150 through the second water suction port 151, and establishes a second siphon connection between the fish tank 101 and the filter cylinder 103.
If the water discharge amount is larger than the water inflow amount, the water level in the fish tank 101 gradually decreases, and when the water level decreases below the second water suction port 151, air enters the second siphon pipeline 150 again to break the siphon, disconnect the second siphon connection, and simultaneously reduce the water discharge amount. Because the water pump 105 continuously conveys the water in the filtering tank 103 into the fish tank 101, the water always flows in the first siphon pipeline 110, and when the water level in the fish tank 101 rises again and the second water suction port 151 is submerged, the second siphon pipeline 150 can resume siphoning again, so that the water displacement is increased. In this way, the water level in the fish tank 101 is fixed to the second water suction port 151, so that the relative balance between the water inflow and the water discharge is achieved.
Because the negative pressure tank 130 increases the local inner diameter of the second siphon pipeline 150, after the siphon is established, the water entering the negative pressure tank 130 cannot fill the negative pressure tank 130, that is, the lower opening of the third air pipe connector 133 cannot contact the water in the negative pressure tank 130, so that the hidden danger of blocking the air pipe 160 is eliminated.
In summary, the negative pressure siphon system 100 provided by the present invention has the following advantages:
in the negative pressure siphon system 100 according to the present invention, first, since the second water suction port 151 can be provided on the water surface, the installation space can be saved and the amount of water to be discharged can be increased. Second, the negative pressure tank 130 can enable the vent pipe 160 to completely leave the water surface, so that the probability of blocking the vent pipe 160 is greatly reduced. Finally, since the pipe diameter of the negative pressure tank 130 is larger than the partial pipe diameter of the second siphon pipeline 150, the negative pressure tank 130 can be filled with a proper filter material 136, which can perform the filtering and purifying functions without sacrificing the drainage. The negative pressure siphon system 100 has compact structure, safety and reliability and great popularization and application value.

Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
