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, most electrical components inside aquariums are currently powered by external plugs, which exposes the wires. This makes them susceptible to contact with the liquid inside the aquarium, posing a significant safety hazard. In addition, the wires are messy and unsightly. 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 of wave generators causing harm to aquarium organisms, difficulty in freely adjusting the wave generation effect, and exposed wires.

[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 wireless power supply module.

[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 wireless power supply module includes an electromagnetic transmitting unit and an electromagnetic receiving unit. The electromagnetic transmitting unit is used to abut against the outer wall of the fish tank, and the electromagnetic receiving unit is used to abut against the inner wall of the fish tank and corresponds to the electromagnetic transmitting unit. The electromagnetic receiving unit is electrically connected to the main control board.

[0010] Optionally, the electromagnetic transmitting unit includes a first mounting base and an electromagnetic transmitting coil, the electromagnetic transmitting coil being installed in the first mounting base; the electromagnetic receiving unit includes a second mounting base and an electromagnetic receiving coil, the second mounting base being connected to the vacuum cylinder, the electromagnetic receiving coil being sealed and installed in the second mounting base and electrically connected to the main control board.

[0011] Optionally, the electromagnetic transmitting unit further includes a magnetic attracting element, which is installed in the first mounting base; the electromagnetic receiving unit further includes a magnetic element, which is installed in the second mounting base, and the magnetic attracting element and the magnetic element attract each other magnetically.

[0012] Optionally, the main control board is sealed and installed in the second mounting base, and the second mounting base has a wiring hole for the electrical connection wire between the main control board and the vacuum pump to pass through the second mounting base.

[0013] Optionally, the electromagnetic receiving unit further includes a connecting ring, which is fixedly sleeved on the vacuum cylinder, and the side of the second mounting base opposite to the first mounting base is connected to the outer peripheral wall of the connecting ring.

[0014] Optionally, the connecting ring is located near the upper negative pressure port, and a support platform is provided on the outer peripheral wall of the connecting ring, with the vacuum pump mounted on the support platform.

[0015] Optionally, the second mounting base includes a base body and a cover body. The base body is integrally formed with the connecting ring. The base body is provided with a receiving groove. The electromagnetic receiving coil is installed in the receiving groove. The cover body seals the receiving groove.

[0016] Optionally, the aquarium wave generator further includes a silencer connected to the vacuum pump.

[0017] Optionally, the control unit further includes a liquid level sensor for detecting the liquid level in the vacuum channel. The main control board is electrically connected to the liquid level sensor to control the vacuum pump to stop pumping based on the liquid level in the vacuum channel.

[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] In addition, by setting an electromagnetic receiving unit that is electrically connected to the main control board on the inner wall of the fish tank, and setting an electromagnetic transmitting unit corresponding to the electromagnetic receiving unit on the outer wall of the fish tank, the main control board, vacuum pump and other electrical components can be wirelessly powered. This avoids the exposed wires inside the fish tank, making the power supply safer and the fish tank more aesthetically pleasing. Attached Figure Description

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

[0034] In the embodiments of this utility model, such as Figures 1 to 5 As shown, the aquarium wave generator includes a vacuum cylinder 10, a vacuum pump 20, a control unit, and a wireless power supply module.

[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 wireless power supply module includes an electromagnetic transmitting unit 40 and an electromagnetic receiving unit 50. The electromagnetic transmitting unit 40 is used to abut against the outer wall of the fish tank, and the electromagnetic receiving unit 50 is used to abut against the inner wall of the fish tank and corresponds to the electromagnetic transmitting unit 40. The electromagnetic receiving unit 50 is electrically connected to the main control board 30.

[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-making 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 electromagnetic transmitting unit 40 and the electromagnetic receiving unit 50 can be fixed to the outer and inner walls of the fish tank respectively by mutual magnetic attraction. Alternatively, they can be fixed to the fish tank wall by adhesive bonding; no specific limitation is made here. It is understood that the electromagnetic transmitting unit 40 and the electromagnetic receiving unit 50 can achieve wireless power transmission. The electromagnetic transmitting unit 40 contains an electromagnetic transmitting coil 42, and the electromagnetic receiving unit 50 contains an electromagnetic receiving coil 52. When the electromagnetic transmitting coil 42 is energized, it generates an alternating magnetic field. Through electromagnetic induction, an induced current is generated in the wireless receiving coil, thereby powering the main control board 30.

[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. Compared with the existing method of creating a wave surge by rotating a propeller, it will not harm the organisms in the aquarium. Moreover, the height of the liquid level can be adjusted as needed. In this way, 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 that green algae can be removed in time.

[0044] In addition, by setting an electromagnetic receiving unit 50 that is electrically connected to the main control board 30 on the inner wall of the fish tank, and setting an electromagnetic transmitting unit 40 corresponding to the electromagnetic receiving unit 50 on the outer wall of the fish tank, electrical components such as the main control board 30 and the vacuum pump 20 can be wirelessly powered, thereby avoiding the exposure of wires inside the fish tank, making the power supply safer, and making the appearance of the fish tank cleaner and more beautiful.

[0045] In one embodiment, such as Figure 4 and Figure 5 As shown, the electromagnetic transmitting unit 40 includes a first mounting base 41 and an electromagnetic transmitting coil 42, with the electromagnetic transmitting coil 42 installed inside the first mounting base 41; the electromagnetic receiving unit 50 includes a second mounting base 51 and an electromagnetic receiving coil 52, with the second mounting base 51 connected to the vacuum cylinder 10, and the electromagnetic receiving coil 52 sealed and installed inside the second mounting base 51 and electrically connected to the main control board 30.

[0046] In this embodiment, the electromagnetic receiving coil 52 is sealed and installed inside the second mounting base 51 and electrically connected to the main control board 30, ensuring the sealing reliability of the electromagnetic receiving coil 52. Thus, when the electromagnetic transmitting coil 42 is energized, an alternating magnetic field is generated. Through electromagnetic induction, an induced current is generated in the wireless receiving coil, thereby powering the main control board 30. The specific structures of the first mounting base 41 and the second mounting base 51 can vary. Typically, the first mounting base 41 and the second mounting base 51 are roughly plate-shaped and adapted to the wall of the aquarium. The electromagnetic transmitting coil 42 can be fixedly installed inside the first mounting base 41 by adhesive, snap-fit, or embedding, and the electromagnetic receiving coil 52 can be fixedly installed inside the second mounting base 51 by adhesive, snap-fit, or embedding. The second mounting base 51 and the vacuum cylinder 10 can be fixedly connected by sleeve, snap-fit, or other methods, without specific limitations. This allows the vacuum cylinder 10 to be fixed to the inner wall of the aquarium via the second mounting base 51 without the need for additional connecting structures, simplifying the overall structure.

[0047] Furthermore, the electromagnetic transmitting unit 40 also includes a magnetic attracting element 43, which is installed in the first mounting base 41; the electromagnetic receiving unit 50 also includes a magnetic element 53, which is installed in the second mounting base 51, and the magnetic attracting element 43 and the magnetic element 53 attract each other magnetically.

[0048] In this embodiment, the magnetic suction component 43 and the magnetic component 53 can specifically be a magnetic plate, a magnetic ring, or multiple magnetic blocks. The magnetic suction component 43 can be fixedly installed in the first mounting base 41 by means of embedding or bonding. The magnetic component 53 can be fixedly installed in the second mounting base 51 by means of embedding or bonding. In this way, the electromagnetic transmitting unit 40 and the electromagnetic receiving unit 50 can be magnetically clamped to the inner and outer walls of the fish tank, so that the electromagnetic transmitting unit 40 and the electromagnetic receiving unit 50 do not need to be additionally bonded to the inner wall of the fish tank. This simplifies the fixed connection between the wireless power supply module and the fish tank, and also effectively prevents the electromagnetic receiving unit 50 from falling off the inner wall of the fish tank due to the failure of the glue after long-term immersion in water. This makes the installation of the vacuum cylinder 10 in the fish tank more stable and reliable.

[0049] Furthermore, the main control board 30 is sealed and installed within the second mounting base 51. The second mounting base 51 has a wiring hole 511 for the electrical connection wires between the main control board 30 and the vacuum pump 20 to pass through the second mounting base 51. In this way, the main control board 30 is sealed and installed within the second mounting base 51, preventing liquid from entering the second mounting base 51 and causing the control unit to malfunction. Moreover, the wiring hole 511 in the second mounting base 51 allows the electrical connection wires between the main control board 30 and the vacuum pump 20 to be routed within the second mounting base 51, preventing exposed wires and thus improving overall safety.

[0050] In one embodiment, such as Figure 1-4 As shown, the electromagnetic receiving unit 50 also includes a connecting ring 54, which is fixedly sleeved on the vacuum cylinder 10. The side of the second mounting base 51 facing away from the first mounting base 41 is connected to the outer peripheral wall of the connecting ring 54.

[0051] In this embodiment, the connecting ring 54 and the second mounting base 51 can be integrally formed or separately formed. To improve the connection strength, the connecting ring 54 and the second mounting base 51 are typically integrally formed. The connecting ring 54 and the vacuum cylinder 10 can be fixedly connected by welding, bonding, interference fitting, or other methods. By setting the connecting ring 54 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 second mounting base 51 can be fixedly connected to the inner wall surface of the fish tank by bonding, hanging, magnetic attraction, or other methods. This makes the vacuum cylinder 10 fixed to the inner wall surface of the fish tank by the connecting ring 54 and the second mounting base 51, making the fixing method simpler and faster. Furthermore, the second mounting base 51 can adapt to the inner wall surface of the fish tank to ensure a reliable connection.

[0052] In one embodiment, please refer to Figure 1-3 The connecting ring 54 is close to the upper negative pressure port 12. The outer peripheral wall of the connecting ring 54 is provided with a support platform 55, and the vacuum pump 20 is installed on the support platform 55.

[0053] In this embodiment, by positioning the connecting ring 54 close to the upper negative pressure port 12 and installing the vacuum pump 20 on a support platform 55 on the connecting ring 54, the vacuum pump 20 and the aquarium do not need to be separately fixed, reducing the difficulty of assembling the aquarium wave generator and making the overall structure more compact. To improve structural strength, the support platform 55 and the connecting ring 54 can optionally be integrally formed. The vacuum pump 20 and the support platform 55 can be fixedly connected by methods such as bonding, welding, or snap-fitting.

[0054] In one embodiment, such as Figure 4 and Figure 5 As shown, the second mounting base 51 includes a base body 512 and a cover body 513. The base body 512 and the connecting ring 54 are integrally formed. The base body 512 has a receiving groove 514, in which the electromagnetic receiving coil 52 is installed. The cover body 513 seals the receiving groove 514. The integral formation of the base body 512 and the connecting ring 54 can improve the connection strength and simplify the connection. The cover body 513 and the shell of the base body 512 are sealed and fixedly connected by means of bonding, sealing and embedding. By setting the cover body 513, it is easier to assemble the electromagnetic receiving coil 52 in the base body 512. In addition, the base body 512 and the cover body 513 are set separately, so the cover body 512 and the base body 512 can be made of different materials. For example, the base body 512 can be made of a material with high structural strength, while the cover body 513 can be made of a material such as rubber with strong adhesion to the inner wall of the fish tank. Moreover, the cover body 513 can also be designed to correspond to the shape of the inner wall of the fish tank.

[0055] In one embodiment, please refer to Figure 1-3 The aquarium wave generator also includes a silencer 60, which is connected to the vacuum pump 20. The silencer 60 can be of many types and can be selected according to actual needs; no specific limitation is made here. By connecting the silencer 60 to the vacuum pump 20, the silencer 60 can reduce the noise of the vacuum pump 20 during operation, thereby ensuring the comfort of the fish's living environment.

[0056] In one embodiment, the control unit further includes a liquid level sensor for detecting the liquid level in the vacuum channel 13. The main control board 30 is electrically connected to the liquid level sensor to control the vacuum pump 20 to stop pumping based on the liquid level in the vacuum channel 13.

[0057] 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.

[0058] 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.

[0059] 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.
