Description

Technical Field

[0001] This application relates to the technical field of filtration equipment, and particularly to an air-lift component, a pneumatic filter with silent water outlet, and an aquarium. Background Art

[0002] Existing aquariums mostly use bubble generators to generate bubbles. The size of these bubbles is usually large. At the same time, since the bubble generator drives the water body to rise through the bubbles, and the dirt in the water will be driven when the water body flows. When the dirt passes through the air holes used to generate bubbles with the water body, it is easy to accumulate and adhere to the air holes, forming scale, resulting in the blockage of the air holes. As a result, gas cannot pass through the air holes smoothly to generate bubbles, causing the volume of water that the same volume of gas can drive to rise to decrease, affecting the efficiency of water filtration. Summary of the Utility Model

[0044] The technical solution of the present application will be further described below in conjunction with embodiments and drawings.

[0045] Please refer to Figures 1 to 3 , in a first aspect, an air-lift assembly 10 provided by an embodiment of the present application is provided. The air-lift assembly 10 is provided with a water body channel and a gas channel communicating with the water body channel. The size of the gas channel gradually decreases along the gas flow direction, and the gas channel has a plurality of air outlets, and the air outlets are located on the inner wall of the water body channel and communicate with the water body channel.

[0046] By providing a water body channel and a gas channel communicating with the water body channel on the air lift assembly 10, the size of the gas channel gradually decreases along the gas flow direction, and the gas channel has a plurality of gas outlets, which can not only help reduce the size of the generated bubbles, but also increase the flow rate of the bubble output, so that the gas forms bubbles at the gas outlets and rises rapidly, increasing the volume of the water body driven by the gas to rise. At the same time, it can also help remove the dirt at the water outlet 21, reducing the dirt accumulation at the gas outlets. Combined with the smaller-sized bubbles, it can reduce the risk of blockage at the water outlet 21, further increasing the volume of the water body driven by the gas to rise and improving the filtration efficiency of the water body. At the same time, by setting the gas outlets on the inner wall of the water body channel, the bubbles are formed on the inner wall of the air lift assembly 10, which helps reduce the water body resistance and increases the volume of the water body driven by the gas to rise, thereby improving the filtration efficiency of the water body.

[0047] Please combine Figures 4 to 7 In some embodiments, the air lift assembly 10 includes a first air lift member 11 and a second air lift member 12. The first air lift member 11 is provided with a first through hole, an air inlet 111 and a water inlet 112. A support boss 13 is convexly provided on the inner wall of the first through hole, so that the first through hole is divided into a first area 113 and a second area 114, and the water inlet 112 communicates with the first area 113, and the air inlet 111 communicates with the second area 114. The second air lift member 12 is installed in the second area 114 and abuts against the support boss 13. A second through hole 121 is provided inside the second air lift member 12, and the second through hole 121 communicates with the first through hole. The second through hole 121 and the first area 113 enclose a water body channel, and the gas outlet is located between the second air lift member 12 and the support boss 13. The second air lift member 12 and the first air lift member 11 enclose a gas channel.

[0048] By enclosing the water body channel and the gas channel with the first air lift member 11 and the second air lift member 12, it is beneficial to the shape design of the gas channel, facilitating the formation of bubbles with smaller size and faster flow rate. Both the air inlet 111 and the water inlet 112 are provided on the first air lift member 11, which makes the installation and design of the second air lift member 12 more flexible. At the same time, the second air lift member 12 is installed in the second area 114 and abuts against the support boss 13, which is beneficial to the assembly and positioning of the air lift assembly 10.

[0049] It can be understood that in some other embodiments, the first air lift member 11 and the second air lift member 12 can also be of an integral structure.

[0050] Optionally, the support boss 13 is provided with a special-shaped groove 131 with an opening facing the second air lift member 12. The special-shaped groove 131 communicates with the second through hole 121, and the size of the special-shaped groove 131 gradually decreases from the inner wall of the first through hole to the center direction of the first through hole. The inner wall of the special-shaped groove 131 and the second air lift member 12 enclose a gas outlet.

[0051] In this way, the gas passage through which the gas passes is gradually reduced by the irregular-shaped groove 131 with gradually decreasing dimensions, which is conducive to increasing the gas flow velocity, thereby facilitating the movement of the dirt at the air outlet, reducing dirt accumulation, and avoiding the blockage of the air outlet. At the same time, the gradually decreasing dimensions of the irregular-shaped groove 131 can also reduce the size of the generated bubbles, which is conducive to forming small bubbles and increasing the contact area between the bubbles and the water body, thereby increasing the volume of the water body driven to rise. In addition, the inner wall of the irregular-shaped groove 131 and the second air-lifting member 12 enclose an air outlet, which can also limit the position of the air outlet, so that the bubbles can rise along the inner wall of the second through-hole 121 after being discharged from the air outlet, which is conducive to reducing the water body resistance, thereby further increasing the volume of the water body driven to rise by the bubbles and improving the water body filtration efficiency.

[0052] Optionally, the shape of the irregular-shaped groove 131 can be triangular, fan-shaped, isosceles trapezoidal, pear-shaped, etc., which can be specifically set according to actual needs and is not limited here.

[0053] Optionally, the second air-lifting member 12 is provided with a second groove 122 communicating with the second through-hole 121. The second groove 122 is located at one end of the second air-lifting member 12 close to the support boss 13, and the second groove 122 communicates with the irregular-shaped groove 131, so that the inner wall of the second groove 122 and the support boss 13 enclose a C-shaped space, which is conducive to controlling the flow direction of the bubbles, so that the bubbles can rise along the inner wall of the second through-hole 121 to reduce the water body resistance and increase the volume of the water body driven to rise by the bubbles.

[0054] In some embodiments, a first groove 123 is provided on the outer periphery of the second air-lifting member 12. The first groove 123 and the inner wall of the second region 114 enclose an annular air cavity 115. The number of the irregular-shaped grooves 131 is multiple, and the air inlet 111 communicates with the multiple irregular-shaped grooves 131 and the annular air cavity 115 respectively.

[0055] In this way, a gas passage is formed by enclosing the first air-lifting member 11 and the second air-lifting member 12. After the gas enters the gas passage through the air inlet 111, it sequentially passes through the annular air cavity 115 and the irregular-shaped groove 131, and finally is discharged to the second through-hole 121 through the air outlet and introduced into the water body to generate bubbles, and the bubbles drive the water body to rise. This is conducive to the structural design of the gas passage, facilitating the generation of smaller-sized bubbles and increasing the bubble flow velocity. At the same time, by providing the annular air cavity 115, it is conducive to dispersing the gas, so that the gas is discharged from different air outlets, thereby making the generated bubbles more evenly distributed in the air-lifting assembly 10, which is conducive to increasing the volume of the water body lifted by the gas under the same volume.

[0056] Optionally, the first air-lifting member 11 is provided with a plurality of air guiding columns 14. The plurality of air guiding columns 14 are spaced apart at one end of the annular air cavity 115 close to the supporting boss 13, and the air guiding columns 14 abut against the inner wall of the first groove 123. Each special-shaped groove 131 is located between two adjacent air guiding columns 14, and the distance between two adjacent air guiding columns 14 is greater than the maximum dimension of the special-shaped groove 131.

[0057] In this way, by providing the air guiding columns 14, a plurality of channels are formed in the annular air cavity 115, so that after the gas enters the annular air cavity 115, it needs to first pass through the space between two adjacent air guiding columns 14 and then enter the special-shaped groove 131, so as to complete the process of the gas flowing in the gradually decreasing gas channels, thereby gradually increasing the flow rate of the gas.

[0058] Optionally, the first air-lifting member 11 is provided with an air guiding hole 116. One end of the air guiding hole 116 communicates with the air inlet 111, and the other end of the air guiding hole 116 communicates with the end of the annular air cavity 115 far from the supporting boss 13, so that the gas sequentially passes through the air inlet 111, the air guiding hole 116, the annular air cavity 115 and the space between two adjacent air guiding columns 14 and enters the special-shaped groove 131, and the size of the air guiding hole 116 is smaller than the size of the air inlet 111.

[0059] Thus, after the gas enters the gas channel through the air inlet 111, the size of the gas channel through which the gas passes gradually decreases, which is beneficial to gradually increasing the flow rate of the gas, reducing the accumulation of dirt and reducing the risk of blocking the air outlet. At the same time, the increase in the flow rate of the gas can also reduce the pressure of the introduced gas, so that a small pressure can generate enough small bubbles, thereby reducing the energy consumption required to drive the gas to enter the air inlet 111 at a certain pressure. In addition, by providing the air guiding hole 116, it is also beneficial to guide the gas to enter the end of the annular air cavity 115 far from the air guiding columns 14, so as to facilitate the gas to flow dispersedly along the circumferential direction of the annular air cavity 115 and enter different special-shaped grooves 131, thereby making the generation positions of the bubbles more uniform, being beneficial to increasing the volume of the water body lifted, and thus improving the filtration efficiency of the water body.

[0060] Optionally, a third groove 124 is further provided on the outer periphery of the second air-lifting member 12. The third groove 124 communicates with the first groove 123 and is provided at the end of the second air-lifting member 12 far from the supporting boss 13. When the second air-lifting member 12 abuts against the supporting boss 13, the top of the first air-lifting member 11 abuts against the inner wall of the third groove 124 and the inner wall of the second region 114 abuts against the inner wall of the third groove 124, so that the annular air cavity 115 can be sealed to seal the gas channel, avoid gas leakage, and thus improve the water body filtration efficiency, and at the same time, the structural stability of the air-lifting assembly 10 can be improved to improve the reliability of the air-lifting assembly 10.

[0061] Please combine with Figures 8 to 10, In a second aspect, the present application also discloses a pneumatic filter 100 with silent water discharge, including the air-lift assembly 10 described in the first aspect above. Thus, the bubble size can be reduced, and the volume of water driven by the gas to rise can be increased to improve the water filtration efficiency.

[0062] Please refer to Figure 11 and Figure 12 , In some embodiments, the pneumatic filter 100 with silent water discharge further includes an antifoaming chamber 20 and a top cover 30. The air-lift assembly 10 is connected to the antifoaming chamber 20 through a pipeline. The top cover 30 is connected to one end of the antifoaming chamber 20 far from the air-lift assembly 10. And a water outlet 21 is provided at the bottom of the antifoaming chamber 20. The water outlet 21 is located below the water surface. The top cover 30 is provided with a first exhaust port 31. The first exhaust port 31 is located above the water surface, so that the bubbles generated by the air-lift assembly 10 burst inside the antifoaming chamber 20.

[0063] In this way, the bubbles burst on the water surface inside the antifoaming chamber 20, and the gas is discharged from the first exhaust port 31 out of the pneumatic filter 100, and the water body is discharged through the water outlet 21. It can ensure that there are no bubble ruptures on the water surface outside the pneumatic filter 100, effectively avoiding the situation where bubbles enter the water body through the water outlet 21 and burst. Thus, the effects of silent operation and splash prevention are achieved. At the same time, by setting the bubbles to burst inside the soundproof chamber, the residence time of the bubbles inside the pneumatic filter 100 can be increased, so as to increase the residence time of the gas in the water body, which is beneficial to improving the dissolved oxygen content in the water body and beneficial to the survival of organisms in the water body.

[0064] Optionally, the antifoaming chamber 20 is provided with a second exhaust port 22. The second exhaust port 22 is correspondingly arranged with the first exhaust port 31, and the top cover 30 is rotatable relative to the antifoaming chamber 20, so that the coincidence degree of the second exhaust port 22 and the first exhaust port 31 can be adjusted. Thus, the conduction size of the first exhaust port 31 can be adjusted to control the gas discharge speed inside the antifoaming chamber 20, which is beneficial to improving the dissolved oxygen content in the water body.

[0065] Optionally, the number of the first exhaust ports 31 and the second exhaust ports 22 is multiple. The multiple first exhaust ports 31 are arranged at intervals along the reverse circumference of the top cover 30, and the multiple first exhaust ports 31 and the multiple second exhaust ports 22 correspond to each other one by one. Thus, it is beneficial to the gas discharge inside the antifoaming chamber 20 and beneficial to adjusting the gas discharge speed of the first exhaust port 31.

[0066] Optionally, the top cover 30 is threadedly connected to the antifoaming chamber 20. Specifically, the top cover 30 is provided with an internal thread, and one end of the antifoaming chamber 20 close to the air-lift assembly 10 is provided with an external thread. When the top cover 30 is threadedly connected to the antifoaming chamber 20, the second exhaust port 22 is located inside the top cover 30. Thus, it can not only meet the relative rotation between the top cover 30 and the antifoaming chamber 20, but also improve the connection reliability between the top cover 30 and the antifoaming chamber 20.

[0067] Please refer to again Figure 8 and Figure 10 In some embodiments, the pneumatic filter 100 with silent water outlet further includes a first air pipe 40, a second air pipe 50 and an air pipe seat 60. The first air pipe 40 is connected to the second air lift member 12 of the air lift assembly 10, the second air pipe 50 is connected to the defoaming chamber 20, and the first air pipe 40 is sleeved with the second air pipe 50. The air pipe seat 60 is sleeved on the outer periphery of the first air pipe 40 and the second air pipe 50 and is movably connected to the first air pipe 40 or the second air pipe 50, so that the sleeved length of the first air pipe 40 and the second air pipe 50 can be adjusted. Thus, the height of the pneumatic filter 100 can be adjusted, so that the pneumatic filter 100 with silent water outlet can be adapted to different application scenarios (such as fish tanks with different depths, etc.).

[0068] Optionally, the first air pipe 40 is inserted into the second air pipe 50. By adjusting the length of the first air pipe 40 extending into the second air pipe 50, the height of the pneumatic filter 100 with silent water outlet can be adjusted.

[0069] It can be understood that in other embodiments, the second air pipe 50 is inserted into the first air pipe 40.

[0070] Optionally, the air pipe seat 60 is sleeved on the outer periphery of the second air pipe 50. The air pipe seat 60 is provided with a movable threaded hole and a locking member. The locking member is threadedly connected to the movable threaded hole to adjust the distance between the locking member and the second air pipe 50. When the locking member is locked with the movable threaded hole, the locking member abuts against the outer periphery of the second air pipe 50, and the first air pipe 40 and the second air pipe 50 are locked and fixed, and the height of the pneumatic filter 100 is fixed. When the locking member is loosened until there is a gap between the locking member and the second air pipe 50, the first air pipe 40 and the second air pipe 50 can move relative to each other, so that the height of the pneumatic filter 100 can be adjusted.

[0071] In a third aspect, the present application also provides an aquarium (not shown), which includes the pneumatic filter 100 with silent water outlet as described in the second aspect above.

[0072] It can be understood that since the aquarium includes the pneumatic filter 100 with silent water outlet as described in the first aspect above, the aquarium has the beneficial effects of the pneumatic filter 100 with silent water outlet as described in the first aspect above, which will not be elaborated here.

However, the present application is not limited to the above embodiments. Various changes can be made without departing from the purpose of the present application within the knowledge scope of those of ordinary skill in the art. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
