Description

Technical Field

[0001] This utility model relates to the field of aquarium supplies technology, specifically to the exhaust structure of a filter cartridge. Background Technology

[0002] Most aquariums on the market are equipped with filtration systems. These systems use filter elements to remove fish waste, secretions, uneaten food, and other waste from the water, thereby regulating various water parameters and maintaining clean, clear, and stable water quality. Chinese Patent Publication No. CN221468741U discloses a bottom-circulating filter aquarium with a filter box at the bottom. To ensure the filtration effect of the filter box, a filter cartridge is often connected to the third filtration zone. The filter cartridge typically contains a large amount of tumbling filter media for water purification. To save space, the filter cartridge is usually placed horizontally. However, horizontally placed filter cartridges contain air, preventing water from completely filling the cartridge. This results in insufficient or insufficient space for the tumbling filter media to tumble, thus reducing the water purification effect. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides an exhaust structure for the filter cartridge, which solves the problem that the water body cannot fill the horizontally placed filter cartridge.

[0004] The technical solution adopted in this utility model is as follows:

[0005] The exhaust structure of the filter cartridge includes a cartridge body, the cartridge body being connected to an inlet pipe and an outlet pipe, and further includes:

[0006] An exhaust pipe is installed inside the cylinder, with one end of the exhaust pipe located at the top of the cylinder and the other end connected to the water outlet pipe;

[0007] The fixing part is located inside the cylinder and is used to cooperate with the exhaust pipe.

[0008] The cylinder is fitted with a first cylinder cover. The fixing part includes a fixing seat disposed on the inner wall of the first cylinder cover and a limiting plate disposed between the fixing seat and the water outlet pipe. The fixing seat is used to cooperate with the top end of the exhaust pipe.

[0009] The top of the first cylinder cover is provided with an outlet, and a threaded cap is installed at the outlet.

[0010] The cylinder is equipped with a No. 1 water pipe for connecting to the inlet pipe and a No. 2 water pipe for connecting to the outlet pipe. Both the No. 1 and No. 2 water pipes are provided with water passage holes arranged at intervals, and the No. 1 water pipe is located above the No. 2 water pipe.

[0011] The No. 1 water pipe is located behind the No. 2 water pipe, which is located at the bottom of the cylinder. The water passages of the No. 1 and No. 2 water pipes are arranged in the same direction. The water passage of the No. 1 water pipe is arranged at an upward angle, while the water passage of the No. 2 water pipe is arranged horizontally.

[0012] The other end of the cylinder is provided with a second cylinder cover. The first cylinder cover is provided with a first connector and a first connecting post. The second cylinder cover is provided with a second connector corresponding to the first connecting post and a second connecting post corresponding to the first connector.

[0013] The beneficial effects of this utility model are:

[0014] The fixing part secures the exhaust pipe inside the cylinder. Air at the top of the cylinder enters the water outlet pipe through the exhaust pipe and is discharged, allowing water to fill the horizontally placed filter cylinder. This provides sufficient space for the tumbling filter media to tumble inside the cylinder, ensuring water purification. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] In the embodiments, such as Figure 1 , Figure 2 As shown, the exhaust structure of the filter cartridge includes a cartridge body 1, which is connected to an inlet pipe and an outlet pipe, and also includes:

[0023] An exhaust pipe 2 is installed inside the cylinder 1, with one end of the exhaust pipe 2 located at the top of the cylinder 1 and the other end connected to the water outlet pipe;

[0024] The fixing part 3 is set inside the cylinder 1 and is used to cooperate with the exhaust pipe 2.

[0025] The fixing part 3 fixes the exhaust pipe 2 inside the cylinder 1. The air at the top of the cylinder 1 enters the water outlet pipe through the exhaust pipe 2 and is discharged, allowing the water to fill the horizontally placed filter cylinder, thus allowing the tumbling filter material to have enough tumbling space inside the cylinder 1 to ensure water purification.

[0026] In the embodiments, such as Figure 2 As shown, the cylinder 1 is fitted with a first cylinder cover 4. The fixing part 3 includes a fixing seat 31 disposed on the inner wall of the first cylinder cover 4 and a limiting plate 32 disposed between the fixing seat 31 and the water outlet pipe. The fixing seat 31 is used to cooperate with the top end of the exhaust pipe 2. The fixing seat 31 fixes the air inlet end of the exhaust pipe 2, and the limiting plate 32 limits the exhaust pipe 2 to prevent the exhaust pipe 2 section located inside the first cylinder cover 4 from moving.

[0027] In the embodiments, such as Figure 1 , Figure 2 , Figure 3 As shown, the top of the first cylinder cover 4 is provided with an outlet 5, and a threaded cap 6 is installed at the outlet 5. The filter media inside the cylinder 1 can be replaced by opening the threaded cap 6 without disassembling the first cylinder cover 4, making filter media replacement convenient.

[0028] In the embodiments, such as Figure 4 As shown, the cylinder 1 is equipped with a first water pipe 7 for connecting to the inlet pipe and a second water pipe 8 for connecting to the outlet pipe. Both the first water pipe 7 and the second water pipe 8 are provided with water passage holes 9 arranged at intervals. The first water pipe 7 is located above the second water pipe 8. The water coming out of the first water pipe 7 enters the second water pipe 8 through the water passage holes 9, forming a downward water flow, which drives the filter media to move downward and improves the tumbling effect of the filter media.

[0029] In the embodiments, such as Figure 4 As shown, the first water pipe 7 is located behind the second water pipe 8, which is positioned at the bottom of the cylinder 1. The water inlets 9 of both the first and second water pipes are arranged in the same direction, with the first water pipe 7's inlet 9 angled upwards and the second water pipe 8's inlet 9 horizontally positioned. Water from the first water pipe 7 is sprayed out at an angle, acting on the filter media. Simultaneously, water is drawn in from the bottom of the cylinder 1, causing the filter media to tumble along the inner wall of the cylinder 1, effectively improving the tumbling effect of the filter media and resulting in better water purification.

[0030] In the embodiments, such as Figure 2 , Figure 5As shown, the other end of the cylinder 1 is provided with a second cylinder cover 10. The first cylinder cover 4 is provided with a first connector 11 and a first connecting post 12. The second cylinder cover 10 is provided with a second connector 13 corresponding to the first connecting post 12 and a second connecting post 14 corresponding to the first connector 11. The first connecting post 12 and the second connector 13 are respectively connected to the two ends of the first water pipe 7, and the first connector 11 and the second connecting post 14 are respectively connected to the two ends of the second water pipe 8. The first water pipe 7 and the second water pipe 8 are easy to assemble and disassemble.

[0031] Obviously, the above embodiments of this utility model are merely illustrative examples and not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
