Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of aquarium aerators, and in particular to an aquarium aerator for absorbing feces. Background Technology
[0002] In order to improve the survival rate of fish, a filtration system is usually installed in the aquarium to purify and filter the water. The filter system is usually installed in a separate filter chamber in the aquarium. The filtered water is then pumped to the fish-keeping area of the aquarium. However, the pump is placed in the water for a long time, which can easily lead to electric leakage. In addition, the filter chamber occupies part of the fish-keeping space, resulting in low space utilization. To solve this problem, a filtration device designed independently of the aquarium and used immediately after being placed in the aquarium has appeared on the market.
[0003] For example, the Chinese utility model patent "Aquarium / Fish Basin Pneumatic Filter" with patent publication number CN210054307U includes a housing, an outlet pipe, an inlet pipe, and an air inlet pipe, all of which extend to the outside of the housing. An air collection hood is installed at the end of the outlet pipe inside the housing and is connected to the outlet pipe. An air stone located directly below the air collection hood is connected at the end of the air inlet pipe inside the housing. An oxygen pump is connected to the end of the air inlet pipe outside the housing via a flexible hose. A filter basket is rotatably connected to the end of the inlet pipe outside the housing. A support ring is fixedly installed inside the housing. A culture ring, a biochemical layer, and a filter layer are arranged sequentially on the top of the support ring. The outlet pipe and the inlet pipe pass through the support ring, the culture ring, the biochemical layer, and the filter layer in sequence.
[0004] In the above scheme, oxygen is introduced into the oxygen hood to generate bubbles, creating negative pressure inside the shell. Under this negative pressure, the water and fish waste in the fish tank or fish basin can only enter the shell for filtration through the inlet pipe, and the filtered water can only flow out of the shell through the outlet pipe. Because the flow rates of the inlet and outlet pipes are limited, the filter has low filtration efficiency and poor filtration effect. Utility Model Content
[0005] This invention addresses the problem that filters in use only deliver water from the aquarium to the housing through the inlet pipe, and the filtered water can only flow out of the housing through the outlet pipe, resulting in low filtration efficiency and poor filtration effect. The technical problem to be solved by this invention is to provide an aquarium waste aerator to solve the above problems.
[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: It includes a hollow shell with a top opening. A water outlet channel extending from the bottom of the shell to the opening is provided inside the shell. An adsorption chamber is formed between the outer wall of the water outlet channel and the inner wall of the shell. A filter device for adsorbing fish waste is provided inside the adsorption chamber. Several water inlets communicating with the adsorption chamber are provided on the side walls of both the shell and the water outlet channel, arranged circumferentially. All water inlets are lower than the top outlet of the water outlet channel. A bubble-generating device is provided inside the water outlet channel. An air inlet channel is provided at the bottom of the shell, with one end connected to the bubble-generating device and the other end connected to an oxygen pump. When the oxygen pump delivers oxygen... The air intake channel delivers air to the bubble generator, which generates bubbles that flow upwards along the water outlet channel and emerge from the opening. The flow of bubbles carries water along the water outlet channel, thus drawing water and fish waste from the aquarium into the bubble generator. The fish waste is adsorbed onto the filter device, while the water, after passing through the filter device, flows out of the shell opening along the water outlet channel with the bubbles. By setting several water inlets circumferentially on the side walls of the shell and the water outlet channel, the water in the aquarium carries the fish waste into the shell through these inlets. After filtration, the water flows out through the opening of the water outlet channel, resulting in a large flow rate that is not limited by pipes, thus improving the filtration efficiency of the filter device.
[0007] A further preferred embodiment of this utility model is as follows: the bubble outlet is an oxygen sand head, and the water inlet is a strip-shaped hole. The strip-shaped hole is used to block the fish and prevent the fish in the aquarium from being sucked into the shell. In order to improve the filtration effect of the filtration device and avoid high local filtration pressure, the water inlets on the shell and the water outlet channel are evenly distributed in a ring array.
[0008] A further preferred embodiment of this utility model is: the bottom of the shell is provided with several strip-shaped adsorption ports that communicate with the adsorption chamber. The strip-shaped adsorption ports can conveniently and quickly clean the bottom of the fish tank that cannot be cleaned in place, and also avoid the bottom of the shell being placed in a cleaning dead corner.
[0009] A further preferred embodiment of this utility model is: the bottom of the shell is provided with a support foot that creates a gap between the bottom of the shell and the bottom of the fish tank, so as to ensure water flow between the bottom of the shell and the bottom of the fish tank and avoid the formation of a stagnant water zone between the bottom of the shell and the bottom of the fish tank.
[0010] A further preferred embodiment of this utility model is as follows: the adsorption chamber is provided with a partition, which divides the adsorption chamber into a filter media chamber and a fish waste separation chamber distributed vertically, the filter media chamber being located above the fish waste separation chamber, and the partition is provided with a drain outlet that connects the filter media chamber and the fish waste separation chamber.
[0011] A further preferred embodiment of this utility model is as follows: the filtration device includes biochemical cotton and several layers of filter media. The biochemical cotton is located in the fish waste separation chamber, and the several layers of filter media are located in the filter media chamber. When the bubble-generating device generates bubbles, the water in the filter media chamber is filtered by the filter media and then enters the fish waste separation chamber from the drain outlet for secondary filtration before flowing into the water outlet channel. The water then flows upward along the water outlet channel with the bubbles and flows out from the opening.
[0012] A further preferred embodiment of this utility model is: the water inlet on the shell and the water outlet channel is located at a position corresponding to the fish waste separation chamber, so that the fish waste separation chamber is connected to the outside of the shell and the bubble outlet device of the water outlet channel respectively.
[0013] A further preferred embodiment of this utility model is as follows: an adsorption chamber is fixedly provided at the opening of the shell and communicates with the opening on the shell. The adsorption chamber is used to place activated carbon. By placing activated carbon, odors in the water can be adsorbed and bacterial growth can be inhibited. The bottom of the adsorption chamber and the inner wall of the top of the shell have a gap to form the opening. Water in the shell flows out of the shell through the opening.
[0014] A further preferred embodiment of this utility model is as follows: the adsorption chamber is an inverted frustum shape with a hollow interior. By designing the adsorption chamber into an inverted frustum shape, when bubbles carry water flow upward along the outlet channel to the adsorption chamber, the adsorption chamber acts as a barrier to disperse the bubbles, allowing them to escape from the opening. This facilitates the dissolution of oxygen in the water, increases the oxygen content of the water, and also prevents splashing. The side wall of the adsorption chamber is provided with strip-shaped through holes evenly distributed in a ring array with the axis of the inverted frustum as the center. The bottom of the adsorption chamber is provided with several vent holes. The adsorption chamber is connected to the opening of the shell through the strip-shaped through holes and the vent holes. The design of the vent holes and strip-shaped through holes allows odors in the water inside the shell to enter the adsorption chamber through the strip-shaped through holes and the vent holes and be adsorbed by activated carbon.
[0015] A further preferred embodiment of this utility model is: the bottom sidewall of the adsorption chamber is provided with support rods evenly distributed in the circumferential direction, the support rods extend outward, and there are at least two support rods fixed to the shell.
[0016] Compared with the prior art, the present invention has the following advantages: by setting several water inlets along the circumference of the shell and the water outlet channel sidewall, when the oxygen pump works and causes the water outlet channel to generate suction, the water and fish waste in the fish tank enter the adsorption chamber for filtration through the multiple water inlets around the shell. Compared with the prior art, the water in the fish tank of the present invention carries the fish waste into the shell through several water inlets. After filtration, the water flows out through the opening of the water outlet channel, resulting in a larger flow rate that is not limited by pipes and improves the filtration efficiency of the filtration device.

[0024] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.
[0025] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.
[0026] This embodiment mainly describes a fish tank waste aerator, as detailed below:
[0027] like Figures 1 to 5As shown, a fish tank waste aerator includes a hollow shell 1 with a top opening 16. A water outlet channel 2 extends from the bottom of the shell 1 to the opening 16 within the shell 1. An adsorption chamber 3 is formed between the outer wall of the water outlet channel 2 and the inner wall of the shell 1. A filter device 4 is installed within the adsorption chamber 3 to adsorb fish waste, separating the water and fish waste in the fish tank and purifying the water. Several water inlets 5 are arranged circumferentially on the side walls of both the shell 1 and the water outlet channel 2. The water inlets 5 are arranged so that both the outside of the shell 1 and the water outlet channel 2 are connected to the adsorption chamber 3. The water inlets 5 are all lower than the top outlet of the water outlet channel 2. A bubble-generating device 6 is installed within the water outlet channel 2. A [missing information - likely a device name] is located at the bottom of the shell 1. One end is connected to the bubble-generating device 6, and the other end is connected to the air intake channel 7 of the oxygen pump. The air intake channel 7 is used to transport oxygen. When the oxygen pump works, it delivers oxygen to the bubble-generating device 6 through the air intake channel 7. The bubble-generating device 6 generates bubbles. The bubbles flow upward along the water outlet channel 2 and emerge from the opening 16. The flow of bubbles drives the water flow along the water outlet channel 2, generating a weak suction. Under the action of suction, the water and fish waste in the fish tank are poured into the bubble-generating device 6. The fish waste in the fish tank first passes through the filter device 4. Under the action of the filter device 4, the fish waste is adsorbed on the filter device 4. After passing through the filter device 4, the water is separated from the fish waste and flows out from the opening 16 of the shell 1 along the water outlet channel 2 with the bubbles. By setting several water inlets 5 arranged circumferentially on the side walls of the shell 1 and the water outlet channel 2, when the oxygen pump works and causes the water outlet channel 2 to generate suction, the water and fish waste in the fish tank enter the adsorption chamber 12 from the water inlets 5 circumferentially on the shell 1 for filtration. The water and fish waste are sucked into the adsorption cotton from multiple directions through the water inlets 5. Compared with the prior art, the present invention adds water flow rate without being affected by flow rate, thus improving the filtration efficiency of the filtration device 4.
[0028] Specifically, the bubble generator 6 is an oxygen sand head, air stone, etc. In order to enhance the suction of the water outlet channel 2 and improve the filtration effect, the position of the bubble generator 6 corresponds to the water inlet 5 of the shell 1 and the water outlet channel 2. At the same time, in order to avoid local high filtration pressure, the water inlets 5 on the shell 1 and the water outlet channel 2 are evenly distributed in a ring array. In order to prevent the suction inside the shell 1 from sucking the fish in the aquarium into the shell 1, the water inlet 5 is a strip-shaped hole.
[0029] like Figure 2 As shown, in order to facilitate and quickly clean the bottom of the fish tank where cleaning is not thorough, and to avoid the bottom of the shell 1 becoming a cleaning dead zone, the bottom of the shell 1 is provided with several legs 9 to create a gap between the bottom of the shell 1 and the bottom of the fish tank. The legs 9 are used to support the shell 1 and at the same time ensure water circulation between the bottom of the shell 1 and the bottom of the fish tank, avoiding stagnant water areas between the bottom of the shell 1 and the bottom of the fish tank. The bottom of the shell 1 is provided with several strip-shaped adsorption ports 8 that communicate with the adsorption chamber 3. The adsorption ports 8 are evenly distributed on the bottom surface of the shell 1.
[0030] like Figure 4 and Figure 5As shown, the adsorption chamber 3 is equipped with a partition 10, which divides the adsorption chamber 3 into a filter media chamber 31 and a fish waste separation chamber 32, which are distributed vertically. The filter media chamber 31 is located above the fish waste separation chamber 32. The partition 10 is provided with a drain outlet 11 that connects the filter media chamber 31 and the fish waste separation chamber 32. The water inlets 5 on the shell 1 and the water outlet channel 2 are located at positions corresponding to the fish waste separation chamber 32, so that the fish waste separation chamber 32 is connected to the outside of the shell 1 and the bubble outlet device 6 of the water outlet channel 2, respectively. The filtration device 4 includes bio-cotton 41 and several layers of filter media 42. The bio-cotton 41 is located in the fish waste separation chamber 32, and the several layers of filter media 42 are located in the filter media chamber 31. When the bubble-generating device 6 generates bubbles, the bubbles drive the water flow upward along the outlet channel 2 to generate suction. Under the action of suction, the water in the filter media chamber 31 is filtered by the filter media 42 and enters the fish waste separation chamber 32 from the drain outlet 11. The bio-cotton 41 in the fish waste separation chamber 32 performs secondary filtration on the water coming down from the filter media chamber 31 and flows into the outlet channel 2. It then flows upward along the outlet channel 2 with the bubbles and flows out from the opening 16. The flow rate of the outlet channel 2 is much greater than the flow rate of the filter media chamber 31 entering the fish waste separation chamber 32 from the outlet.
[0031] Specifically, an adsorption chamber 12, communicating with the opening 16 on the shell 1, is fixedly installed at the opening 16 of the shell 1. The adsorption chamber 12 is used to hold activated carbon, which adsorbs odors in the water and inhibits bacterial growth. The bottom of the adsorption chamber 12 and the inner wall of the top of the shell 1 have an opening 16 formed by a gap, through which water flows out of the shell 1. The adsorption chamber 12 is a hollow, inverted frustum shape. The side wall of the adsorption chamber 12 has strip-shaped through holes 13 evenly distributed in a ring around the axis of the inverted frustum. The bottom of the adsorption chamber 12 has several vent holes 14. The adsorption chamber 12 communicates with the opening 16 of the shell 1 through the strip-shaped through holes 13 and the vent holes 14. Odors in the water inside the shell 1 can enter the adsorption chamber 12 through the strip-shaped through holes 13 and the vent holes 14 and be adsorbed by the activated carbon. Meanwhile, the adsorption chamber 12 is designed in the shape of an inverted frustum. When the bubbles carry the water flow upward along the water outlet channel 2 to the adsorption chamber 12, the adsorption chamber 12 acts as a barrier to the water bubbles, causing them to disperse and allowing them to emerge from the opening 16. This facilitates the dissolution of oxygen in the water, increases the oxygen content of the water, and also prevents splashing.
[0032] Specifically, the bottom sidewall of the adsorption chamber 12 is provided with support rods 15 evenly distributed in the circumferential direction. The support rods 15 extend outward, and there are at least two support rods 15 fixed to the shell 1.

[0034] The above provides a detailed description of the aquarium waste aerator provided by this utility model.

The above description of the embodiments is only for the purpose of helping to understand this utility model and its core ideas. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
