Description

Technical Field

[0001] This utility model relates to the technical field of fish tanks and their accessories, and in particular to a wave-making device for fish tanks and a wave-making fish tank. Background Technology

[0002] In current aquarium designs, many use propellers to create waves to simulate natural water flow and surges. However, propellers generate tremendous noise when rotating at high speeds, severely impacting fish behavior and growth. Furthermore, the propeller blades rotate at extremely high speeds, and if aquarium creatures accidentally come into contact with the rotating blades, they can suffer serious physical injury. This injury is often fatal, especially for small fish and fragile organisms. Moreover, current propeller wave-generating systems often lack precise parameter adjustment capabilities, making it difficult for users to freely control the wave effect according to the needs and preferences of the aquarium's inhabitants. This results in wave effects that are often too simplistic and fail to meet the diverse needs of different organisms for water flow and surges.

[0003] Furthermore, current disinfection lamps are usually installed inside the filtration system. Although they have a significant sterilization and disinfection effect, they can easily damage the nitrifying bacteria in the filtration system, thereby disrupting the water quality balance and affecting the health of fish. Utility Model Content

[0004] The main purpose of this invention is to propose a wave generator for aquariums, which aims to solve the technical problems that wave generators can harm aquarium organisms and make it difficult to freely adjust the wave generation effect, as well as the problem that disinfection lamps installed in the filtration system can easily destroy nitrifying bacteria.

[0005] To achieve the above objectives, the aquarium wave generator proposed in this utility model includes a vacuum cylinder, a vacuum pump, a control unit, and a disinfection lamp;

[0006] The vacuum cylinder is provided with a lower negative pressure port, an upper negative pressure port and a vacuum channel. The vacuum channel connects the lower negative pressure port and the upper negative pressure port. The vacuum cylinder is used to install in the fish tank so that the lower negative pressure port is below the liquid surface and the upper negative pressure port is above the liquid surface.

[0007] The vacuum pump is connected to the upper negative pressure port to draw air from the vacuum channel;

[0008] The control unit includes a main control board, which is electrically connected to the vacuum pump. The control unit is used to control the vacuum pump to draw air from the vacuum channel and then control the vacuum pump to depressurize, so that the vacuum cylinder draws the liquid in the fish tank upward and then releases it back down to form a surge.

[0009] The disinfection lamp is installed in the vacuum cylinder and is used to emit disinfection light into the vacuum channel.

[0010] Optionally, the vacuum cylinder is made of a light-transmitting material, and the cylinder wall of the vacuum cylinder is provided with a sandwich groove, which is located between the outer and inner peripheral surfaces of the vacuum cylinder, and the disinfection lamp is sealed and installed in the sandwich groove.

[0011] Optionally, the interlayer groove extends along the length direction of the vacuum cylinder, and the disinfection lamp includes an ultraviolet lamp strip, the length direction of which is consistent with the length direction of the interlayer groove.

[0012] Optionally, the number of the interlayer grooves is at least two, and the at least two interlayer grooves are arranged at intervals along the circumference of the vacuum cylinder. The number of ultraviolet lamp strips is the same as the number of interlayer grooves, and each ultraviolet lamp strip is installed in each of the interlayer grooves.

[0013] Optionally, the top of the interlayer groove is provided with a disassembly port, which extends upward through the top wall of the vacuum cylinder, and the disassembly port is used for inserting or removing the ultraviolet lamp strip into the interlayer groove.

[0014] Optionally, the upper wall of the vacuum cylinder is provided with an annular wiring interlayer, which is located between the disassembly port and the top wall of the vacuum cylinder. The wiring interlayer is used to allow wires to extend from one of the ultraviolet lamp strips to connect with the other ultraviolet lamp strips.

[0015] Optionally, the aquarium wave generator further includes a connecting frame, which includes a connecting ring and a fixing seat. The connecting ring is fixedly sleeved on the vacuum cylinder, and the fixing seat is connected to the outer peripheral wall of the connecting ring. The fixing seat is used to fix the aquarium to the inner wall. The main control board is sealed and installed in the fixing seat. The inner peripheral wall of the connecting ring has a wiring hole that passes through the inner cavity of the fixing seat. The outer peripheral wall of the vacuum cylinder has a wire-passing hole that connects the wiring hole to the interlayer groove, so that the wire can extend from the inner cavity of the fixing seat to the interlayer groove.

[0016] Optionally, the aquarium wave generator further includes a sealing cover, which includes a cover body and a sealing plug connected to the cover body. The cover body is placed on the top of the vacuum cylinder and seals the cable tray. The sealing plug is sealed at the top port of the vacuum cylinder. The gap between the sealing plug and the vacuum cylinder is sealed by a sealing ring. The upper negative pressure port is opened on the sealing cover.

[0017] Optionally, the control unit further includes a liquid level sensor and a timer. The liquid level sensor is used to detect the liquid level in the vacuum channel. Both the liquid level sensor and the timer are electrically connected to the main control board, so that the main control board controls the vacuum pump to stop pumping and controls the timer to start timing according to the liquid level in the vacuum channel, and controls the vacuum pump to depressurize after a preset time after the vacuum pump stops pumping.

[0018] This utility model also proposes a wave-generating aquarium, including an aquarium body and a wave-generating device as described in any of the above embodiments. The wave-generating device is installed inside the aquarium body such that the lower negative pressure port of the wave-generating device is located below the liquid surface, and the upper negative pressure port of the wave-generating device is located above the liquid surface.

[0019] This aquarium wave generator includes a vacuum cylinder, a vacuum pump, and a control unit. The control unit controls the vacuum pump to draw air from the vacuum channel of the vacuum cylinder, and then controls the vacuum pump to depressurize, so that the liquid in the aquarium can be drawn upward from the lower negative pressure port of the vacuum cylinder into the vacuum channel and then released back down to form a wave surge. Therefore, this aquarium wave generator creates waves by drawing a vacuum, which, compared with the existing method of creating waves by rotating a propeller, will not harm the organisms in the aquarium. Moreover, the height of the liquid level can be adjusted as needed, so users can select the wave size according to actual needs and achieve free control of the wave generation effect. In addition, the vacuum column is relatively easy to clean, so it can promptly remove the green algae that grows.

[0020] Furthermore, by utilizing the vacuum chamber to install the sterilization lamp, the lamp does not need to be installed within the filtration system, thus avoiding damage to beneficial bacteria such as nitrifying bacteria within the filtration system and better maintaining water quality balance. Moreover, the sterilization lamp's installation within the vacuum chamber allows the aquarium wavemaker to simultaneously sterilize the liquid within the vacuum channel and the vacuum chamber itself while creating waves, ensuring water cleanliness in the aquarium and preventing algae growth within the vacuum chamber, making cleaning the vacuum chamber easier.

[0033] This utility model proposes a wave-generating device for aquariums.

[0034] In the embodiments of this utility model, such as Figure 1-5 As shown, the aquarium wave generator includes a vacuum cylinder 10, a vacuum pump 20, a control unit, and a disinfection lamp 40.

[0035] The vacuum cylinder 10 is provided with a lower negative pressure port 11, an upper negative pressure port 12 and a vacuum channel 13. The vacuum channel 13 connects the lower negative pressure port 11 and the upper negative pressure port 12. The vacuum cylinder 10 is used to install in the fish tank so that the lower negative pressure port 11 is below the liquid surface and the upper negative pressure port 12 is above the liquid surface.

[0036] Vacuum pump 20 is connected to upper negative pressure port 12 to draw air from vacuum channel 13;

[0037] The control unit includes a main control board 30, which is electrically connected to the vacuum pump 20. The control unit is used to control the vacuum pump 20 to draw air from the vacuum channel 13 and then control the vacuum pump 20 to depressurize, so that the vacuum cylinder 10 draws the liquid in the fish tank upward and then releases it back down to form a surge.

[0038] The disinfection lamp 40 is installed in the vacuum cylinder 10 and is used to emit disinfection light towards the vacuum channel 13.

[0039] In this embodiment, the vacuum cylinder 10 is typically cylindrical to facilitate vacuum suction. The length and diameter of the vacuum cylinder 10 can be selected and designed according to actual needs, and are not specifically limited here. To enhance the wave-generating effect, the lower negative pressure port 11 should be relatively large. Optionally, the lower end of the vacuum cylinder 10 is open to form the lower negative pressure port 11, and the inner cavity of the vacuum cylinder 10 forms the vacuum channel 13. The upper negative pressure port 12 of the vacuum cylinder 10 can be configured according to the specific structure of the suction end of the vacuum pump 20, and is not specifically limited here. Since the vacuum cylinder 10 is used for installation inside the fish tank, there are many ways to fix the vacuum cylinder 10 to the inner wall of the fish tank. For example, the vacuum cylinder 10 can be fixed to the inner wall of the fish tank by adhesive, magnetic attraction, hanging, etc. The method of fixing the vacuum cylinder 10 to the inner wall of the fish tank is not specifically limited here.

[0040] A vacuum pump 20 refers to a pump that uses mechanical, physical, chemical, or physicochemical methods to generate negative pressure (a pressure lower than atmospheric pressure) within the pump, thereby drawing gas molecules from the vacuum cylinder 10 and gradually achieving a vacuum state within the cylinder 10. The vacuum pump 20 can have various structures and forms, and different types and specifications can be selected and designed according to actual needs. Optionally, the vacuum pump 20 uses a diaphragm air pump. This diaphragm air pump has advantages such as small size, light weight, high installation efficiency, and energy saving. It is understood that the suction end of the vacuum pump 20 is connected to the upper negative pressure port 12 of the vacuum cylinder 10 and is sealed to the inner circumferential wall of the vacuum cylinder 10. Thus, when the lower negative pressure port 11 of the vacuum cylinder 10 is below the surface of the aquarium liquid and the vacuum pump 20 is not operating, the vacuum channel 13 will not contain liquid but will be filled with air.

[0041] The main control board 30 can be controlled externally via remote control, buttons, etc. This main control board 30 is electrically connected to the vacuum pump 20. Upon receiving a wave-generating activation signal, the main control board 30 can control the vacuum pump 20 to operate, drawing air from the vacuum channel 13 of the vacuum cylinder 10, creating negative pressure within the vacuum cylinder 10. Due to this pressure difference, the liquid in the aquarium is drawn into the vacuum channel 13, causing the water level inside the vacuum cylinder 10 to rise and the water level outside the vacuum cylinder 10 to fall. Once the water level inside the vacuum cylinder 10 reaches a preset position, the vacuum pump 20 is depressurized, causing the water level in the vacuum channel 13 to rapidly drop due to gravity, thus creating a wave surge. To enhance the wave-generating effect, the vacuum pump 20 can be kept pressurized for a preset time after the water level in the vacuum cylinder 10 reaches the preset position. The control unit can control and adjust the water level rise height in the vacuum channel 13 by controlling the operating time of the vacuum pump 20, thereby freely controlling the size of the wave surge. The working time, pressure holding time, and pressure release time of vacuum pump 20 can be designed according to actual needs, and no specific limitations are made here.

[0042] The disinfection lamp 40 can be installed on the inner wall of the vacuum cylinder 10, embedded in the cylinder wall of the vacuum cylinder 10, or located on the outer wall of the vacuum cylinder 10. In this case, a light-shielding device should be placed around the disinfection lamp 40 to prevent the disinfection light from directly irradiating the organisms in the aquarium. It is understood that since the disinfection lamp 40 emits disinfection light towards the vacuum channel 13, at least the portion of the inner wall of the vacuum cylinder 10 corresponding to the disinfection lamp 40 should be made of transparent or semi-transparent material to allow the disinfection lamp 40 to disinfect the liquid within the vacuum channel 13. The disinfection lamp 40 can have various shapes, such as a long strip or a ring. No specific limitations are placed on the shape and arrangement of the disinfection lamp 40, as long as it can disinfect the liquid within the vacuum channel 13.

[0043] This aquarium wave generator includes a vacuum cylinder 10, a vacuum pump 20, and a control unit. The control unit controls the vacuum pump 20 to draw air from the vacuum channel 13 of the vacuum cylinder 10, and then controls the vacuum pump 20 to depressurize, so that the liquid in the aquarium can be drawn upward from the lower negative pressure port 11 of the vacuum cylinder 10 into the vacuum channel 13 and then released back down to form a wave surge. Therefore, this aquarium wave generator creates a wave surge by drawing a vacuum, which, compared with the existing method of creating a wave surge by rotating a propeller, will not harm the organisms in the aquarium. Moreover, the height of the liquid level can be adjusted as needed, so users can select the wave size according to actual needs and achieve free control of the wave generation effect. In addition, the vacuum column is relatively easy to clean, so it can promptly remove the green algae that grows.

[0044] Furthermore, by fully utilizing the vacuum cylinder 10 to install the disinfection lamp 40, the disinfection lamp 40 does not need to be installed inside the filtration system, thus avoiding damage to beneficial bacteria such as nitrifying bacteria within the filtration system and better maintaining water quality balance. Moreover, with the disinfection lamp 40 installed inside the vacuum cylinder 10, the aquarium wave generator can simultaneously disinfect and sterilize the liquid within the vacuum channel 13 and the vacuum cylinder 10 while creating waves, ensuring water cleanliness in the aquarium and preventing algae growth within the vacuum cylinder 10, making cleaning the vacuum cylinder 10 easier.

[0045] In one embodiment, please refer to Figure 2-5 The vacuum cylinder 10 is made of a light-transmitting material. The cylinder wall of the vacuum cylinder 10 is provided with a sandwich groove 14, which is located between the outer and inner circumferential surfaces of the vacuum cylinder 10. The disinfection lamp 40 is sealed and installed in the sandwich groove 14.

[0046] In this embodiment, the vacuum cylinder 10 is made of a light-transmitting material, allowing the disinfection light from the disinfection lamp 40 to illuminate a wider area within the vacuum channel 13, thus improving the disinfection effect. Furthermore, by sealing the disinfection lamp 40 within the interlayer groove 14 of the vacuum cylinder 10 wall, the disinfection requirements are met while achieving a sealed assembly of the lamp 40, making assembly within the vacuum cylinder 10 more convenient and quick. To prevent the disinfection lamp 40 from affecting the organisms in the aquarium, a light-shielding material can be coated onto the outer surface of the vacuum cylinder 10.

[0047] Furthermore, the interlayer groove 14 extends along the length of the vacuum cylinder 10, and the disinfection lamp 40 includes an ultraviolet lamp strip, the length of which is aligned with the length of the interlayer groove 14. Using an ultraviolet lamp strip for disinfection ensures effective disinfection. By aligning the length of the ultraviolet lamp strip with the length of the interlayer groove 14, the ultraviolet lamp strip can disinfect the entire length of the vacuum channel 13, thereby increasing the disinfection range and effectiveness.

[0048] In one embodiment, such as Figure 5As shown, there are at least two interlayer grooves 14, and the at least two interlayer grooves 14 are arranged at intervals along the circumference of the vacuum cylinder 10. The number of ultraviolet lamp strips is the same as the number of interlayer grooves 14, and each ultraviolet lamp strip is installed in each interlayer groove 14.

[0049] In this embodiment, the number of UV lamps can be selected and designed according to actual needs. Optionally, four UV lamps are provided, arranged evenly around the circumference of the vacuum cylinder 10. By setting multiple UV lamps at intervals around the circumference of the vacuum cylinder 10, the circumference of the vacuum cylinder 10 can be disinfected. Thus, after the vacuum channel 13 is filled with liquid, the liquid in the vacuum channel 13 can be disinfected in all directions (360 degrees), thereby improving the disinfection effect. Furthermore, the number of interlayer grooves 14 is the same as the number of UV lamps, so that each UV lamp is embedded in one interlayer groove 14, making it easier to disassemble and replace the UV lamps.

[0050] Furthermore, the top of the interlayer groove 14 is provided with a disassembly port 15, which extends upwards through the top wall of the vacuum cylinder 10. The disassembly port 15 is used for inserting or removing the ultraviolet lamp strip into the interlayer groove 14. In this way, after the ultraviolet lamp strip fails, the user can disassemble and replace the ultraviolet lamp strip through the disassembly port 15, thereby improving the convenience of disassembling and installing the ultraviolet lamp strip and thus improving the reliability of the aquarium wave generator.

[0051] In one embodiment, please refer to Figure 3 The upper wall of the vacuum cylinder 10 is provided with an annular wiring interlayer 16. The wiring interlayer 16 is located between the disassembly port 15 and the top wall of the vacuum cylinder 10. The wiring interlayer 16 is used to allow wires to extend from one of the UV lamp strips to connect with other UV lamp strips. By providing this annular wiring interlayer 16 inside the vacuum cylinder 10, the connecting wires of multiple UV lamp strips can be routed within the wiring interlayer 16, thereby concealing the connecting wires of the UV lamp strips, avoiding exposed wires, reducing safety hazards, and improving the neatness and aesthetics of the product.

[0052] In one embodiment, such as Figure 1-3 As shown, the aquarium wave generator also includes a connecting frame 50, which includes a connecting ring 51 and a fixing seat 52. The connecting ring 51 is fixedly sleeved on the vacuum cylinder 10, and the fixing seat 52 is connected to the outer peripheral wall of the connecting ring 51. The fixing seat 52 is used to fix the aquarium to the inner wall. The main control board 30 is sealed and installed in the fixing seat 52. The inner peripheral wall of the connecting ring 51 is provided with a wiring hole 53, which passes through the inner cavity of the fixing seat 52. The outer peripheral wall of the vacuum cylinder 10 is provided with a wire-passing hole, which connects the wiring hole 53 to the interlayer groove 14 so that the wire can extend from the inner cavity of the fixing seat 52 to the interlayer groove 14.

[0053] In this embodiment, the connecting ring 51 and the fixing base 52 can be integrally formed or separately formed. To improve the connection strength, the connecting ring 51 and the fixing base 52 are usually integrally formed. The connecting ring 51 and the vacuum cylinder 10 can be fixedly connected by welding, bonding, interference fitting, etc. By setting the connecting ring 51 around the outer periphery of the vacuum cylinder 10, the installation stability of the vacuum cylinder 10 can be improved, effectively preventing the vacuum cylinder 10 from shaking. The fixing base 52 can be fixedly connected to the inner wall surface of the fish tank by bonding, hanging, magnetic attraction, etc. This makes the vacuum cylinder 10 fixed to the inner wall surface of the fish tank by the connecting bracket 50, and the fixing method is simpler and faster. Moreover, the fixing base 52 can be adapted to the inner wall surface of the fish tank to ensure a reliable connection.

[0054] Thus, the main control board 30 is sealed and installed within the mounting base 52, preventing liquid from entering the mounting base 52 and causing the control unit to malfunction. Furthermore, a wiring hole 531 is provided within the connecting ring 51, extending through the inner cavity of the mounting base 52. This allows the connecting wires between the disinfection lamp 40 and the main control board 30 to be routed through the interlayer groove 14, the mounting base 52, and the connecting ring 51, preventing the connecting wires between the disinfection lamp 40 and the main control board 30 from being exposed, thereby improving overall safety.

[0055] Furthermore, there are two connecting brackets 50, which are spaced apart along the length of the vacuum cylinder 10. This allows both the upper and lower sides of the vacuum cylinder 10 to be connected to the inner wall of the aquarium via the connecting brackets 50, thereby further improving the stability of the connection between the vacuum cylinder 10 and the aquarium and effectively preventing the vacuum cylinder 10 from shaking during wave generation and affecting the wave generation effect.

[0056] In one embodiment, please refer to Figure 1-3 The aquarium wave generator also includes a sealing cover 60, which includes a cover body 61 and a sealing plug 62 connected to the cover body 61. The cover body 61 covers the top of the vacuum cylinder 10 and seals the wiring interlayer 16. The sealing plug 62 seals the top port of the vacuum cylinder 10. The gap between the sealing plug 62 and the vacuum cylinder 10 is sealed by a sealing ring 63. The upper negative pressure port 12 is opened on the sealing cover 60.

[0057] In this embodiment, the sealing cap 60 and the vacuum cylinder 10 are separate, with the sealing cap 60 covering the top port of the vacuum cylinder 10, making it easier to clean the inside of the vacuum cylinder 10. The sealing plug 62 can be specifically sealed to the top port of the vacuum cylinder 10 using a rubber ring, silicone ring, etc. By sealing the wiring interlayer 16 with the cap 61, overall integrity and consistency can be ensured, and water or dust can be prevented from entering the wiring interlayer 16. Thus, the suction end of the vacuum pump 20, the pipeline, and the sealing cap 60 are sealed together, preventing air leakage between the vacuum pump 20, the pipeline, the upper negative pressure port 12, and the vacuum channel 13. Therefore, when the vacuum pump 20 is not working, and the vacuum cylinder 10 is placed in the fish tank with the upper negative pressure port 12 above the liquid surface and the lower negative pressure port 11 below the liquid surface, the vacuum channel 13 will not be filled with liquid but with air. When the vacuum pump 20 is working, it can draw air from the vacuum channel 13, thereby filling the vacuum channel 13 with liquid to create waves.

[0058] In one embodiment, the control unit further includes a liquid level sensor and a timer. The liquid level sensor is used to detect the liquid level in the vacuum channel 13. Both the liquid level sensor and the timer are electrically connected to the main control board 30 so that the main control board 30 controls the vacuum pump 20 to stop pumping and controls the timer to start timing according to the liquid level in the vacuum channel 13, and controls the vacuum pump 20 to depressurize after a preset time after the vacuum pump 20 stops pumping.

[0059] In this embodiment, the structure and type of the liquid level sensor can be varied. For example, it can be a float-type, capacitive, or other contact-type liquid level sensor, or a laser or radar-type liquid level sensor. The selection and design can be made according to actual needs, and the specific type of liquid level sensor is not limited here. This liquid level sensor can accurately detect the liquid level height within the vacuum channel 13. Thus, when the liquid level sensor detects that the liquid level in the vacuum channel 13 has risen to a preset height, it can promptly feed back a signal to the main control board 30, thereby enabling the control unit to accurately control the wave size.

[0060] Furthermore, by setting a timer, the pressure holding time of the vacuum pump 20 from stopping suction to depressurization can be accurately controlled. During this pressure holding time, the disinfection lamp 40 can disinfect the liquid in the vacuum channel 13, thus extending the disinfection time and improving the disinfection effect. Simultaneously, the main control board 30 can freely control the disinfection time of the disinfection lamp 40 through this timer to meet different disinfection needs.

[0061] This utility model also proposes a wave-generating aquarium, which includes an aquarium body and a wave-generating device. The specific structure of the wave-generating device is as described in the above embodiments. The wave-generating device is installed inside the aquarium body, such that the lower negative pressure port 11 of the wave-generating device is below the liquid surface, and the upper negative pressure port 12 of the wave-generating device is above the liquid surface. Since this wave-generating aquarium adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here. The shape of the aquarium body can be varied, such as a cube, cuboid, or cylinder, which can be selected and designed according to actual needs. There are also many ways to connect the wave-generating device to the inner wall of the aquarium body, such as adhesive bonding, magnetic fixation, etc.

[0062] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
