Description

Technical Field

[0001] The utility model relates to the field of aquarium equipment, and more specifically to a bubble splash prevention device. Background Art

[0002] To ensure the normal survival of oxygen-consuming organisms in the fish tank, the water body in the fish tank needs to have sufficient oxygen content. Regarding how to ensure the oxygen content of the water body, one measure is to use an oxygen pump and a bubble stone. This oxygenation measure is the most direct and effective. The oxygen pump is connected to the bubble stone through an air pipe, and the bubble stone is immersed in the water body in the fish tank. The bubble stone will disperse the air from the oxygen pump into numerous small bubbles, and the small bubbles come into full contact with the water, thereby realizing the aeration and oxygenation of the water body in the fish tank.

[0003] However, although the above method can achieve the oxygenation of the water body in the fish tank, there are still some deficiencies:

[0004] Firstly, the bubbles emerging from the bubble stone will burst after rising to the surface of the water body in the fish tank. When the bubbles burst, they will splash on the inner side wall of the fish tank, the fish tank cover or the lamp above the fish tank. Since the bubbles are randomly distributed on the water surface, when the bubble stone is aerated for a long time, a layer of scale that is extremely difficult to clean will adhere to the inner side wall of the fish tank, the tank cover or the lampshade of the fish tank light. On the one hand, it affects the beauty, and on the other hand, it affects the illumination of the fish tank light.

[0005] Secondly, when the fish tank uses a filter cartridge for filtration, the water inlet pipe in the fish tank is generally provided with a float for removing oil film. Under normal circumstances, the oil film on the water surface will flow into the filter cartridge through the float. However, due to the random arrangement of the above-mentioned bubbles on the water surface, the bubbles may be introduced into the float, causing the float to fail to float reliably and suck the oil film on the water surface. Seriously, it will cause the filter cartridge to collect air and affect the filtration.

[0006] Thirdly, the bubble stone in the fish tank is connected to the oxygen pump outside the fish tank by a flexible plastic air pipe. A part of this air pipe is immersed in water for a long time, and a large amount of viscous substances will be generated on the outer surface of the air pipe. On the one hand, it affects the health of the fish, and on the other hand, it affects the aesthetics; moreover, the plastic air pipe located inside the fish tank is randomly arranged, making the inside of the fish tank look messy and affecting the aesthetics.

[0007] Fourthly, the bubble stone and the oxygen pump are connected through an air pipe. The bubble stone is provided with an insertion tube, and the insertion tube is inserted into the air pipe. The oxygen pump is provided with a tower-shaped insertion tube, which is also inserted into the air pipe. However, as the use time becomes longer and the air pipe ages, the air pipe will be disconnected from the insertion tube. At this time, the bubble stone no longer emits gas. When the above-mentioned disconnection of the air pipe occurs at night, relevant personnel cannot observe it in time, and it is very likely to cause the fish to lack oxygen.

[0008] In view of the above problems, the prior art also provides some solutions. The prior art uses a vertically arranged pipe body. The upper end of the pipe body is above the water surface. A pipe is arranged inside the pipe body. One end of the pipe is connected to a bubble stone through an air pipe. The bubble stone is located inside the pipe body and below the water surface. The other end of the pipe is connected to an oxygen increasing pump. The pipe body is fixed on the inner side wall of the fish tank by means of a suction cup or hanging. The bubbles emerging from the bubble stone are all gathered inside the pipe body, so that the bubbles will not be randomly dispersed in the fish tank. The solution of the prior art only solves the deficiencies of the above first and second points, and the third and fourth points are still not solved.

[0009] Therefore, how to provide a bubble splash-proof device that can overcome the above problems is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0045] Embodiment

[0046] See the appendix Figures 1 - 9 It is a schematic diagram of the overall and partial structures of an implementation manner of the present utility model. The present utility model specifically discloses a bubble splash-proof device, which includes:

[0047] A tube body, which is vertically and detachably fixed in the fish tank 10. The upper end of the tube body can be located above the water surface in the fish tank 10. An air inlet channel 20, a ventilation groove 21 and a water-permeable through hole 22 are provided on the tube body. One end of the air inlet channel 20 is in air circuit connection with the air outlet end of an aerator outside the fish tank 10, the other end of the air inlet channel 20 is communicated with the ventilation groove 21, the ventilation groove 21 is communicated with the inside of the tube body, and the inside of the tube body and the inside of the fish tank 10 are communicated through the water-permeable through hole 22.

[0048] An air-permeable part 3, on which a plurality of air-permeable holes penetrating through its two end walls are provided. The aperture sizes of the air-permeable holes are different, but the maximum aperture is still much smaller than the inner diameter of the insertion tube 29. One end of the air-permeable part 3 is hermetically covered at the notch of the ventilation groove 21. The ventilation groove 21 is communicated with a plurality of air-permeable holes. The air-permeable part 3 is located inside the tube body and can be located below the water surface in the fish tank 10.

[0049] Specifically, an annular stepped surface is integrally formed inside the ventilation groove 21. The stepped surface is perpendicular to the depth direction of the ventilation groove 21, and glue is applied on the stepped surface. The air-permeable member 3 is adhered to the stepped surface by glue. The air-permeable member 3 in this application belongs to the prior art, and its functional principle is the same as that of components such as air stones and aeration discs in the prior art. Compared with the air stone for aquariums in the prior art, the air-permeable member 3 in this application only has a different external shape structure, and the materials and processing and forming methods of the two are the same. Moreover, the air stone for aquariums in the prior art is generally equipped with a connecting pipe and is connected to an oxygenation pump through the connecting pipe. However, since the air-permeable member 3 in this application is encapsulated at the notch of the ventilation groove 21, and the ventilation groove 21 is connected to the air outlet end of the oxygenation pump, therefore, the air-permeable member 3 in this application does not require an additional connecting pipe to be designed, and the function of the ventilation groove 21 is the same as that of the above-mentioned connecting pipe.

[0050] The pipe body includes a transparent pipe 1 and an air outlet seat 2. The transparent pipe 1 can be vertically arranged in the fish tank 10, and the upper end of the transparent pipe 1 can be located above the water surface in the fish tank 10. The air outlet seat 2 is detachably fixed in the fish tank 10. An air inlet channel 20, a ventilation groove 21, a water permeable through hole 22, and an annular groove 23 are provided on the air outlet seat 2. Both the ventilation groove 21 and the water permeable through hole 22 are limited within the area surrounded by the annular groove 23. The lower end of the transparent pipe 1 can be tightly inserted into the annular groove 23. Since the transparent pipe 1 is inserted into the annular groove 23, when cleaning the transparent pipe 1 or the air outlet seat 2, the transparent pipe 1 can be directly pulled out from the annular groove 23, and the disassembly and assembly of the transparent pipe 1 and the air outlet seat 2 are convenient. By designing the water permeable through hole 22 on the air outlet seat 2, the water inside the transparent pipe 1 and the water in the fish tank 10 can achieve circulation and exchange.

[0051] Specifically, in this embodiment, the inner contour and the outer contour of the cross section of the transparent pipe 1 are both circular. The material of the transparent pipe 1 can be acrylic or glass. Considering the wear resistance during the later cleaning process, the material of the transparent pipe 1 in this embodiment is glass. The transparent pipe 1 can be vertically arranged in the fish tank 10, and the upper end of the transparent pipe 1 can be located above the water surface in the fish tank 10. The bubbles rising inside the transparent pipe 1 will gather inside the transparent pipe 1, and the bubbles will not be randomly scattered on the water surface in the fish tank 10.

[0052] An insertion pipe 29 is also integrally formed on the air outlet seat 2. One end of the air inlet channel 20 away from the ventilation groove 21 is communicated with the insertion pipe 29, and the insertion pipe 29 can be communicated with the air outlet end of the oxygenation pump through an air pipe.

[0053] More specifically, it further includes a lamp 4 and a wire 5. An installation groove 24 and a wire threading channel 25 are also provided on the air outlet base 2. The installation groove 24 is located within the area surrounded by the annular groove 23. The lamp 4 is installed in the installation groove 24, and the light-emitting end of the lamp 4 is arranged towards the upper end of the transparent tube 1. The irradiation direction of the lamp 4 is the same as the length direction of the transparent tube 1. Transparent potting glue is filled in the installation groove 24, and the lamp 4 is immersed in the transparent potting glue. One end of the wire threading channel 25 communicates with the installation groove 24. One end of the wire 5 can be electrically connected to an external power source, and the other end of the wire 5 is electrically connected to the lamp 4 after passing through the wire threading channel 25. The lamp 4 is immersed in the transparent potting glue, thus ensuring the waterproofness of the lamp 4. After the wire 5 is arranged in the wire threading channel 25, potting glue can also be filled in the wire threading channel 25 to prevent water from entering the wire threading channel 25.

[0054] There are two purposes for designing the lamp 4. One is to improve the aesthetics of the splash-proof device, and the device can play a lighting role at night. The other is to prompt the working state of the air-permeable part 3. At night, after the lamp 4 is powered on, it can illuminate the bubbles that escape from the air-permeable part 3 and rise. If the air circuit between the aerator and the ventilation groove 21 is disconnected or the aerator is damaged at night, the user can timely and clearly observe whether there are rising bubbles in the transparent tube 1, avoiding oxygen deficiency in the water body of the fish tank 10.

[0055] Regarding the shapes of the ventilation groove 21 and the installation groove 24 and their layout inside the annular groove 23, there are the following several forms:

[0056] The first one is: the ventilation groove 21 is annular and is coaxially arranged with the annular groove 23. The corresponding air-permeable part 3 is also annular, and the installation groove 24 is centrally arranged within the area surrounded by the ventilation groove 21. This form can achieve the lamp 4 emitting light in the center within the area surrounded by the annular groove 23, and bubbles rising upward outside the lamp 4.

[0057] The second one is: there are multiple installation grooves 24, and the multiple installation grooves 24 are circumferentially and evenly arranged around the center line of the annular groove 23. The ventilation groove 21 is centrally arranged within the area surrounded by the multiple installation grooves 24. This form can achieve bubbles rising in the middle while the periphery of the air-permeable part 3 emits light.

[0058] The third one is: the installation groove 24 is annular and is coaxially arranged with the annular groove 23. The ventilation groove 21 is centrally arranged within the area surrounded by the installation groove 24, and multiple lamps 4 are circumferentially and evenly arranged in the installation groove 24. This form can also achieve bubbles rising in the middle and the periphery of the air-permeable part 3 emitting light.

[0059] The fourth one is: there are multiple ventilation grooves 21, and the multiple ventilation grooves 21 are circumferentially and evenly arranged around the center line of the annular groove 23. The installation groove 24 is centrally arranged within the area surrounded by the multiple ventilation grooves 21. This form can also achieve light emission in the middle and bubbles rising upward outside the lamp 4.

[0060] The bottom wall of the annular groove 23 is provided with an installation through hole 26 penetrating the outer wall of the air outlet seat 2; the purpose of designing the installation through hole 26 is to facilitate the disassembly and assembly of the transparent tube 1 in the annular groove 23. Since the transparent tube 1 is tightly inserted into the annular groove 23, during the process of inserting or pulling out the transparent tube 1, the installation through hole 26 can maintain the air pressure balance in the annular groove 23, and the transparent tube 1 is easy to disassemble and assemble.

[0061] More specifically, a limiting ring 27 is integrally formed on the air outlet seat 2, and the transparent tube 1 can be tightly inserted into the limiting ring 27, and the limiting ring 27 is arranged close to the upper end of the transparent tube 1; when the transparent tube 1 is relatively long, in order to ensure the reliable connection and fixation between the transparent tube 1 and the air outlet seat 2, the limiting ring 27 can be sleeved on the transparent tube 1. Since the annular groove 23 and the limiting ring 27 are respectively arranged at both ends of the transparent tube 1, therefore, the transparent tube 1 is not likely to tilt or come out of the annular groove 23.

[0062] There are three ways to fix the air outlet seat 2 to the fish tank 10 as follows:

[0063] The first way is by magnetic attraction. A first magnet block 6 is fixed on the air outlet seat 2, and the air outlet seat 2 can be closely attached to the inner side wall of the fish tank 10. A second magnet block 7 can be arranged outside the fish tank 10, and the first magnet block 6 and the second magnet block 7 can magnetically attract each other. One side wall of the fish tank 10 can be clamped and limited between the mutually attracting first magnet block 6 and second magnet block 7; for the fixation of the first magnet block 6 to the air outlet seat 2, specifically, a receiving groove 28 is provided on the air outlet seat 2. After the first magnet block 6 is embedded into the receiving groove 28, potting glue is added to the receiving groove 28, and the first magnet block 6 is immersed in the potting glue. On the one hand, it ensures that the first magnet block 6 will not contact water and avoid corrosion of the first magnet block 6. On the other hand, the first magnet block 6 can be reliably fixed in the receiving groove 28.

[0064] The second way is by hanging. A hook 8 is integrally formed on the air outlet seat 2, and the hook 8 can hook on the upper end of the side wall of the fish tank 10.

[0065] The third way is by adsorption. A plurality of suction cups 9 are fixed on the air outlet seat 2, and the suction cups 9 can adsorb on the inner side wall of the fish tank 10;

[0066] Considering the flexible layout and fixed stability of the device, in this embodiment, the air outlet seat 2 is fixed to the fish tank 10 by the above-mentioned magnetic attraction method; the first magnet block 6 and the second magnet block 7 in this embodiment are both rectangular bodies. The air outlet seat 2 has a contact surface, and this contact surface is parallel to the axis line of the transparent tube 1, and this contact surface can be closely attached to the inner side wall of the fish tank 10; the contact surface is located between the first magnet block 6 and the side wall of the fish tank 10.

[0067] When the device is in use, first put one end of the trachea on the intubation tube 29, then connect the other end of the trachea to the air outlet end of the aerator, then fix the air outlet seat 2 in the fish tank 10, and finally insert the transparent tube 1 into the annular groove 23; at night, the wire 5 can be connected to an external power supply.

[0068] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other.

[0069] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
