Description

Technical Field

[0001] This utility model relates to the field of aquarium filtration technology, and in particular to an electric and pneumatic siphon dual-purpose aquarium filter. Background Technology

[0002] A reverse airlift filter is a biological filter used in aquariums. It works by cultivating nitrifying bacteria to break down ammonia and nitrite in the water, converting them into non-toxic nitrate. The device utilizes the effect of airflow on water flow. An air pump at the bottom introduces oxygen, drawing water in, and then the air and water are expelled from the other end. This process physically filters the water and mixes oxygen with it, providing ample oxygen for the nitrifying bacteria to better decompose harmful substances in the aquarium.

[0003] Current biochemical filters have some drawbacks: 1. Existing biochemical filters use filter cotton for filtration. Although there are reserved spaces for installing filter cotton, the installation is relatively troublesome. 2. Existing biochemical filters use an external air pump to pump in oxygen, but if the air pump has a problem, it cannot be used, and it cannot be driven by other means. 3. Existing biological filters still suffer from insufficient oxygen-water mixing.

[0004] To address the above issues, we have provided a new technical solution. Utility Model Content This utility model aims to solve at least one of the technical problems existing in the prior art.

[0022] This utility model provides a dual-purpose electric and pneumatic siphon aquarium filter, such as... Figure 1 , 2 As shown in Figures 3, 4, and 5, including... The filter chamber 10 is divided into at least one filter cavity 20 and a circulation cavity 30 within its internal space. The filter cavity 20 is connected to the outside of the filter chamber 10, and the circulation cavity 30 is connected to the filter cavity 20. Filter cotton (not shown in the figure) is removably filled into circulation chamber 30 and / or filter chamber 20; The lower circulation channel 40 is vertically arranged inside the circulation chamber 30, and an inlet channel communicating with the circulation chamber 30 is provided on the lower circulation channel 40. The air intake passage has one end connected to the lower end of the lower circulation passage 40, and the other end extends through the circulation chamber 30 to the outside of the filter chamber 10. The upper circulation channel is vertically positioned above the filter chamber 10, and its lower end is connected to the upper end of the lower circulation channel 40. The water-air mixing pump outlet 70 is connected to the upper end of the upper circulation channel; An electric water pump 80 is installed on the upper circulation channel. The flow channel of the electric water pump 80 is connected vertically to any section of the upper circulation channel, and its flow channel is in an open state under normal conditions.

[0023] This aquarium filter has two usage methods: 1. Install this aquarium filter on the aquarium / fish tank. The water in the aquarium / fish tank must at least cover the inlet channel of the lower circulation channel 40. Connect the air inlet channel to the external air pump. The air pump pumps air into the air inlet channel, and the air moves from bottom to top, flowing along the lower circulation channel 40, the electric water pump 80, and the upper circulation channel before exiting from the water-air mixing pump outlet 70. Since the filter chamber 20 is connected to the outside of the filter compartment 10, and the circulation chamber 30 is connected to the filter chamber 20, the aquarium / fish tank ... Water from the aquarium can enter the filter chamber 20 and the circulation chamber 30. Under the influence of airflow siphon, the water in the aquarium can rush into the circulation chamber 30 more quickly. At the same time, the water is drawn into the lower circulation channel 40 through the inlet channel, and then flows from bottom to top through the flow channel of the electric water pump 80 and the upper circulation channel before flowing out from the water-air mixing pump outlet 70. During this process, the airflow and water flow are fully mixed, providing sufficient oxygen for nitrifying bacteria, enabling them to better decompose harmful substances in the aquarium.

[0024] 2. Install this aquarium filter on the aquarium / fish tank. The water in the aquarium / fish tank must at least cover the inlet channel of the lower circulation channel 40. Since the filter chamber 20 is connected to the outside of the filter compartment 10 and the circulation chamber 30 is connected to the filter chamber 20, the water in the aquarium / fish tank can enter the filter chamber 20 and the circulation chamber 30. Start the electric water pump 80 to create negative pressure in the upper circulation channel. The water in the aquarium / fish tank is drawn in and sucked into the lower circulation channel 40 through the inlet channel. Then, it flows from bottom to top through the flow channel of the electric water pump 80 and the upper circulation channel before flowing out from the water-air mixing pump outlet 70. During this process, the water circulates and fully mixes with the oxygen in the air, providing sufficient oxygen for the nitrifying bacteria, enabling them to better decompose harmful substances in the aquarium.

[0025] This invention provides two working modes. Water can be drawn in via a pump-in airflow, which creates a siphon effect, carrying the water upwards and outwards. During this process, water and oxygen are combined. Alternatively, water can be drawn in directly from below by an electric water pump 80, flowing upwards and outwards, thus enhancing water flow and also promoting water-oxygen combination. Furthermore, as water enters the filter chamber 20 from outside the filter compartment 10 and then flows into the circulation chamber 30, the filter cotton intercepts, adsorbs, and filters out solid impurities, simultaneously optimizing the water quality environment. The filter cotton is detachably filled within the chambers and can be removed and replaced at any time without installation, making it very convenient.

[0026] In some embodiments of this utility model, such as Figure 1 , 2 As shown in Figures 3 and 4, the upper circulation channel is the upper circulation pipe 50, and the air intake channel is the air intake pipe 60.

[0027] In some embodiments of this utility model, the lower circulation channel 40 includes a lower circulation pipe and a flower basket arranged vertically. The air inlet channel is connected to the bottom of the flower basket, and the lower end of the lower circulation pipe is connected to the top of the flower basket. An air stone, also known as a bubble stone, is provided inside the flower basket. When the air pump delivers air to the lower circulation channel 40 through the air inlet channel, the air will disperse in the pores inside the air stone and then be released into the water in the form of fine bubbles from the numerous tiny pores on the surface of the air stone. As these fine bubbles rise, they increase the contact area with the water, allowing oxygen in the air to dissolve into the water more efficiently, thereby further increasing the dissolved oxygen content in the water.

[0028] In some embodiments of this utility model, such as Figure 1 , 2 As shown in Figures 3 and 4, the circulation chamber 30 is located in the middle of the filter chamber 10. The filter chamber 20 includes two chambers, which are respectively located on both sides of the filter chamber 10. The filter chamber 20 has a top water inlet and a side water inlet 11 on its top and the outer side away from the circulation chamber 30, respectively. This results in a large water intake and improved filtration efficiency. The side water inlet 11 is a water inlet opened on the outer wall of the filter chamber 10. A chamber cover 12 is provided at the top water inlet. A water inlet cover is provided on the chamber cover. A water inlet hole is provided at the water inlet cover.

[0029] In some embodiments of this utility model, the upper circulation channel and the lower circulation channel 40 are detachably connected. The upper circulation channel is divided into upper and lower sections and is detachably connected to the upper and lower ends of the electric water pump 80. This patented technology features a multi-part detachable connection structure, which greatly facilitates packaging and storage. Users can assemble it according to their needs during use, such as... Figure 6 In the embodiment shown, the electric water pump 80 is not assembled in the upper circulation channel. When in use, it is directly connected to an external air pump. However, in this case, the second method of use cannot be used, that is, the method of using the electric water pump 80 to pump water cannot be used.

[0030] In some embodiments of this utility model, such as Figure 1 , 2 As shown in Figures 3 and 5, the water-air mixing pump nozzle 70 has a duckbill-shaped structure, which optimizes the directionality, stability, and adaptability of the water flow output by imitating the morphological characteristics of a duckbill.

[0031] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
