Description

Technical Field

[0001] The utility model relates to the technical field of fish tank accessories, in particular to an oxygenation filter. Background Art

[0002] With the improvement of people's living standards, ornamental fish have become one of the favorite pets of many families. In the process of fish breeding, maintaining good water quality is an important condition to ensure the healthy survival of fish. Adequate dissolved oxygen content plays a key role in maintaining the water quality of the fish tank. Although traditional fish tank filters can complete the task of filtering and purifying water quality well, they are often not effective in oxygenating the water or are not flexible enough in regulation.

[0003] The fish tank filters currently on the market usually use air pumps to oxygenate the water, but there are some shortcomings. For example, the air pump makes a lot of noise when running, affecting the quiet environment of the room. In addition, the oxygenation amount of traditional filters often cannot be adjusted according to actual needs, resulting in insufficient or excessive dissolved oxygen, and unable to provide the most suitable living environment for fish of different densities. In addition, the traditional water volume control mechanism design is often too simple to achieve fine water flow regulation, and it is difficult to meet the needs of fish tanks of different sizes and different fish.

[0004] Therefore, how to design an intelligent and efficient oxygenation filter to achieve fine control of water flow and oxygenation amount, and at the same time meet the dissolved oxygen demand of ornamental fish while taking into account user-friendly features such as easy operation and low noise, has become an urgent problem to be solved in this field. Utility Model Content

[0005] The purpose of the utility model is to overcome at least one defect in the prior art and provide an oxygenation filter which can effectively improve the oxygenation efficiency and control the noise.

[0006] In order to solve the above problems, the utility model provides an oxygenation filter, including a shell, an adapter connected to the shell, and an air conduction pipe connected to the adapter. A water injection chamber and a water suction pump are provided in the shell, an oxygenation pipeline is formed inside the adapter, the water suction pump is arranged at the inlet of the oxygenation pipeline and is used to extract water in the water injection chamber, the oxygenation pipeline is a Venturi tube structure as a whole, including a first tapered section that gradually narrows and a second tapered section that gradually expands, the two tapered sections are tightly connected at their respective narrow mouths, and the air conduction pipe is connected to the oxygenation pipeline at the narrow mouth connection of the two tapered sections.

[0007] Compared with the prior art, the utility model is beneficial in that: in the design of the utility model, the aeration pipeline adopts a special Venturi tube structure, which includes two tapered sections that gradually narrow and then gradually expand. In the first tapered section, the water flow speed increases as the pipe cross section decreases, resulting in a decrease in static pressure, thereby generating a negative pressure at the narrowest throat where the first tapered section and the second tapered section are connected. The air conduction pipe is connected to the throat, and the negative pressure causes the air to be sucked into the aeration pipeline and fully mixed with the water flow in the second tapered section that is subsequently expanded. This design cleverly utilizes the Venturi effect, and realizes the automatic absorption and effective dissolution of air through physical methods, thereby improving the oxygenation efficiency of the water body and achieving the technical purpose of improving the oxygenation effect; in addition, since the shell of the utility model is placed in water when in use, the operation process of the entire filter is carried out underwater, which effectively reduces the chance of noise being transmitted to the air. Therefore, the utility model achieves the purpose of oxygenation, and at the same time, the filter also achieves low-amplitude noise generation, providing a quieter fish tank environment.

[0008] As an improvement, a bend section is provided between the wide-mouth starting part of the first conical section and the entrance of the aeration pipe. After applying this structure, the setting of the bend section causes a certain degree of turbulence in the water flow before entering the first conical section, which helps to break up the bubbles in the water flow and make the water flow enter the narrowing part of the venturi tube more evenly. Therefore, when the water flow passes through the narrowest part of the aeration pipe again, the water flow pre-treated by the bend section is more conducive to forming a stable and strong negative pressure effect, which not only further promotes the inhalation of air and the aeration effect of the water flow, but also makes the mixed water flow more delicate and reduces the noise generated by the impact of the water body, thereby effectively improving the efficiency of the entire aeration process and the user experience.

[0009] As an improvement, the cross section of the second tapered section is square. After applying this structure, the square outlet design can effectively reduce the concentration of water flow compared to the round outlet, making the water flow distance shorter and the distribution more uniform and gentle, thus significantly reducing the damage to fish, especially in aquaculture or ornamental fish ponds, which helps to improve the living environment of fish. In addition, the softer water flow is also conducive to simulating the natural water environment and better meeting the living needs of fish.

[0010] As an improvement, at least one suction cup assembly is provided on the outer side wall of the shell. After applying this structure, the suction cup assembly can firmly adsorb the shell on various smooth surfaces, such as glass or tiles, ensuring stability and reliability during use. In addition, the design of the suction cup also allows the user to easily adjust the position or angle of the shell to adapt to different use environments and needs, thereby improving the flexibility and practicality of the product.

[0011] As an improvement, a grille water inlet connected to the water injection cavity is provided on the outer wall of the shell. After applying this structure, the grille water inlet design allows water to enter the water injection cavity evenly and quickly, which not only improves the water injection efficiency, but also effectively prevents impurities from entering and maintains internal cleanliness.

[0012] As an improvement, a water volume regulating valve for adjusting the water volume of the water pump is provided at the water inlet of the water pump. After applying this structure, the water volume regulating valve can allow users to accurately control the water volume of the water pump according to actual needs, which can not only effectively avoid the interference of excessive water flow on the water ecology, but also ensure that the water pump works in the best state, reduce energy consumption, and extend the service life of the pump. By adjusting the water volume, it can also adapt to water environments of different sizes or different needs, further improving the adaptability and practicality of the equipment.

[0013] As an improvement, the water volume regulating valve includes a fixed part, a rotating part and a dial block, the fixed part has a plurality of first through holes, the rotating part is provided with a plurality of second through holes corresponding to the first through holes, the rotating part is arranged on the fixed part to rotate around a fixed axis and is used to change the alignment state between the first through holes and the second through holes according to the rotation angle, and the dial block is fixed on the rotating part and is used to drive the rotating part to rotate through user operation. After applying this structure, the user can drive the rotating part to rotate by intuitively and conveniently operating the dial block to change the alignment state between the first through hole and the second through hole, thereby accurately regulating the water intake. Since there are multiple corresponding through holes, it also allows the water volume to be adjusted more delicately and in multiple levels, and the ideal water control effect can be quickly achieved under different needs, which enhances the flexibility of the product and the convenience of use.

[0014] As an improvement, an air intake regulating valve for adjusting the air intake of the air conduit is provided at the air inlet of the air conduit. After applying this structure, the air intake regulating valve can accurately control the amount of gas entering the air conduit, allowing the user to adjust the air flow according to different working environments and requirements. This adjustment mechanism facilitates real-time monitoring and adjustment of the gas flow, ensures the stability and efficiency of the system operation, and thus improves the performance and reliability of the overall equipment.

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] like Figures 1 to 4 As shown, in the utility model, the oxygenation filter comprises a shell 1, an adapter 2 connected to the shell 1, and an air conduction pipe 3 connected to the adapter 2. A water injection chamber 10 and a water suction pump 11 are provided in the shell 1. An oxygenation pipe 4 is formed inside the adapter 2. The water suction pump 11 is provided at the inlet of the oxygenation pipe 4 and is used to extract water in the water injection chamber 10. The oxygenation pipe 4 is a Venturi tube structure as a whole, including a gradually narrowing first conical section 41 and a gradually expanding second conical section 42. The two conical sections are closely connected at their respective narrow mouths, and the air conduction pipe 3 is connected to the oxygenation pipe 4 at the narrow mouth connection of the two conical sections.

[0024] Compared with the prior art, the utility model is beneficial in that: in the design of the utility model, the oxygenation pipe 4 adopts a special Venturi tube structure, which includes two tapered sections that gradually narrow and then gradually expand. In the first tapered section 41, the water flow speed increases as the pipe cross section decreases, resulting in a decrease in static pressure, thereby generating a negative pressure at the narrowest throat portion where the first tapered section 41 and the second tapered section 42 are connected. The air conduit 3 is connected to the throat, and the negative pressure causes the air to be sucked into the oxygenation pipe 4 and fully mixed with the water flow in the second tapered section 42 that is subsequently expanded. This design cleverly utilizes the Venturi effect, and realizes the automatic absorption and effective dissolution of air through physical methods, thereby improving the oxygenation efficiency of the water body and achieving the technical purpose of improving the oxygenation effect; in addition, since the housing 1 of the utility model is placed in water when in use, the operation process of the entire filter is carried out underwater, effectively reducing the chance of noise being transmitted to the air. Therefore, the utility model achieves the purpose of oxygenation, and at the same time, the filter also achieves low-amplitude noise generation, providing a quieter fish tank environment.

[0025] In order to electrically connect the water suction pump 11 to the power supply outside the housing 1 , a threading hole communicating with the inside and outside of the housing 1 is provided on the outer wall of the housing 1 of the utility model, and the cable of the water suction pump 11 is passed through the threading hole.

[0026] like Figures 2 to 3 As shown, a bend section 43 is provided between the wide-mouth starting portion of the first tapered section 41 and the inlet of the aeration pipe 4. After the structure is applied, the setting of the bend section 43 causes a certain degree of turbulence in the water flow before entering the first tapered section 41, which helps to break up the bubbles in the water flow and allows the water flow to enter the narrowing part of the venturi tube more evenly. Therefore, when the water flow passes through the narrowest part of the aeration pipe 4 again, the water flow pre-treated by the bend section 43 is more conducive to forming a stable and strong negative pressure effect, which not only further promotes the inhalation of air and the aeration effect of the water flow, but also makes the mixed water flow more delicate and reduces the noise generated by the impact of the water body, thereby effectively improving the efficiency of the entire aeration process and the user experience.

[0027] Furthermore, the cross section of the second tapered section 42 is square. After applying this structure, the square outlet design can effectively reduce the concentration of water flow compared to the round outlet, so that the outlet flow distance is shorter and the distribution is more uniform and gentle, thereby significantly reducing the damage to fish, especially in aquaculture or ornamental fish ponds, which helps to improve the living environment of fish. In addition, the gentler water flow is also conducive to simulating the natural water environment and better meeting the living needs of fish.

[0028] like Figure 1 As shown, at least one suction cup assembly 5 is provided on the outer side wall of the housing 1. After applying this structure, the suction cup assembly 5 can firmly adsorb the housing 1 on various smooth surfaces, such as glass or tiles, to ensure stability and reliability during use. In addition, the design of the suction cup also allows the user to easily adjust the position or angle of the housing 1 to adapt to different use environments and needs, thereby improving the flexibility and practicality of the product.

[0029] like Figure 3 As shown, a grille water injection port 6 connected to the water injection chamber 10 is provided on the outer wall of the housing 1. After applying this structure, the grille water injection port 6 is designed so that water can enter the water injection chamber 10 evenly and quickly, which not only improves the water injection efficiency, but also effectively prevents impurities from entering and maintains internal cleanliness.

[0030] like Figure 3As shown, a water volume regulating valve 7 for regulating the water intake of the water pump 11 is provided at the water inlet of the water pump 11. After applying this structure, the water volume regulating valve 7 can allow the user to accurately control the water intake of the water pump 11 according to actual needs, which can not only effectively avoid the interference of excessive water flow on the water ecology, but also ensure that the water pump works in the best state, reduce energy consumption, and extend the service life of the pump. By adjusting the water intake, it can also adapt to water environments of different sizes or different needs, further improving the adaptability and practicality of the equipment.

[0031] like Figure 5 As shown, the water volume regulating valve 7 includes a fixed portion 71, a rotating portion 72 and a shifting block 73. The fixed portion 71 has a plurality of first through holes 710, and the rotating portion 72 has a plurality of second through holes 720 corresponding to the first through holes 710. The rotating portion 72 is rotatably disposed on the fixed portion 71 around a fixed axis and is used to change the alignment state between the first through holes 710 and the second through holes 720 according to the rotation angle. The shifting block 73 is fixed on the rotating portion 72 and is used to drive the rotating portion 72 to rotate through user operation. In order to allow the user to operate the shifting block 73 from the outside of the housing 1, an operating channel connecting the inside and outside of the housing 1 is also opened on the outer wall of the housing 1 of the utility model. The free end of the shifting block 73 is inserted into the operating channel and can rotate around the fixed axis in the operating channel. After applying this structure, the user can drive the rotating part 72 to rotate through the intuitive and convenient operation dial 73 to change the alignment state of the first through hole 710 and the second through hole 720, and then accurately adjust the water intake. Since there are multiple corresponding through holes, it also allows the water volume to be adjusted more delicately and in multiple levels. The ideal water control effect can be quickly achieved under different needs, which enhances the flexibility and convenience of the product.

[0032] like Figure 1 or Figure 4 As shown, an air intake regulating valve 8 for regulating the air intake amount of the air conduit 3 is provided at the air inlet of the air conduit 3. After applying this structure, the air intake regulating valve 8 can accurately control the amount of gas entering the air conduit 3, allowing the user to adjust the air flow according to different working environments and requirements. This adjustment mechanism facilitates the real-time monitoring and adjustment of the gas flow, ensures the stability and efficiency of the system operation, and thus improves the performance and reliability of the overall equipment.

[0033] Although the disclosure is as above, the protection scope of the disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the protection scope of the utility model.
