Description

Technical Field

[0001] This utility model relates to the technical field of aquarium equipment, and in particular to an ultrasonic pressure-driven oxygenation pump. Background Technology

[0002] Traditional aquarium air pumps mostly use electromagnetic vibration or motor-driven piston or cup valves to compress gas, which results in problems such as high noise, strong vibration, and low energy efficiency. In particular, electromagnetic air pumps, operating at a 50Hz power frequency, are prone to generating audible noise due to mechanical vibration and airflow pulsation, affecting the user experience.

[0003] Therefore, a type of oxygen pump with a symmetrical double-chamber drive has emerged on the market. This pump uses a motor to simultaneously drive two symmetrical cups, allowing their vibrations to balance and cancel each other out, thus reducing vibration problems. However, this type of oxygen pump is still a mechanical reciprocating motion structure. While it can balance vibration to some extent, the noise and energy consumption generated during mechanical reciprocating motion remain unresolved.

[0004] Therefore, there is an urgent need for a new type of oxygen pump to reduce vibration and noise during oxygen supply and to reduce energy consumption. Utility Model Content

[0005] To address the problems mentioned above, this invention provides an ultrasonic pressure-driven oxygenation pump that utilizes high-frequency ultrasonic vibration to drive airflow for oxygenation, thereby reducing vibration and noise during oxygenation and effectively lowering energy consumption.

[0006] The solution adopted by this utility model to solve its technical problem is: an ultrasonic sound pressure driven oxygenation pump, comprising:

[0007] The middle frame contains at least one independent pump body mechanism, which has a pump chamber and at least one first gas passage and at least one second gas passage connecting the pump chamber.

[0008] An ultrasonic actuator, disposed within the pump chamber, is configured to vibrate under a high-frequency voltage signal above 20 kHz to form an ultrasonic standing wave, thereby propelling gas into the first gas channel and out through the second gas channel; or propelling gas into the second gas channel and out through the first gas channel; and,

[0009] The first cover plate and the second cover plate are respectively installed on the two side ports of the middle frame and close the middle frame. The surface of the first cover plate, the surface of the second cover plate, or the surface of the middle frame is provided with ventilation holes that communicate with the outside.

[0010] Furthermore, the middle frame includes a first frame and a second frame that are spliced ​​together. A first pump body portion is integrally formed in the first frame, and a second pump body portion is integrally formed in the second frame. The first pump body portion and the second pump body portion are spliced ​​together to form the pump body mechanism and enclose the pump cavity inside the pump body mechanism.

[0011] Furthermore, the ultrasonic actuator is sandwiched between the first pump body and the second pump body and divides the pump chamber into a first chamber and a second chamber. The first chamber and the second chamber are each equipped with an independent first gas channel and a second gas channel. The second gas channel is positioned opposite the ultrasonic actuator and is equipped with a one-way valve. When the ultrasonic actuator vibrates, the two one-way valves open and close alternately.

[0012] Furthermore, the one-way valve is positioned directly opposite the antinode of the ultrasonic actuator.

[0013] Furthermore, a drive board is provided inside the middle frame, the ultrasonic actuator is electrically connected to the drive board, and the drive board is provided with a power supply interface for power supply.

[0014] Furthermore, the power supply interface is a USB interface.

[0015] Furthermore, a power supply battery is also installed inside the middle frame, and the power supply battery is electrically connected to the drive board.

[0016] Furthermore, the drive plate is electrically connected to a regulator for adjusting the air output, and the first cover plate, the second cover plate, or the middle frame is provided with an adjustment knob connected to the regulator.

[0017] Furthermore, a filter cotton covering the ventilation hole is detachably installed at the location where the ventilation hole is provided on the first cover plate, the second cover plate, or the middle frame.

[0018] Furthermore, an air intake gap is formed between the filter cotton and the vent hole.

[0019] In summary, the beneficial effects of this utility model are as follows: By setting a pump body mechanism within the middle frame and installing an ultrasonic actuator in the pump chamber of the pump body mechanism, the ultrasonic actuator can vibrate under the drive of a high-frequency voltage signal, thereby pumping gas through the first gas channel and the second gas channel to deliver oxygen. The working frequency is above 20kHz, which is beyond the range of human hearing, thus effectively eliminating noise. Furthermore, by directly driving the gas using sound pressure without mechanical transmission, the energy conversion efficiency is effectively improved, thereby reducing energy consumption, and it is also easy to achieve miniaturization design.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Example 1:

[0032] like Figures 1 to 3 As shown, an ultrasonic sound pressure driven oxygen pump can use high-frequency ultrasonic vibration to drive oxygen supply to aquariums, fish tanks, and other aquaculture equipment. Without a mechanical transmission structure, it not only effectively reduces vibration and noise during operation but also lowers energy consumption. Its compact size enhances the user experience. The oxygen pump in this embodiment includes a middle frame 1, an ultrasonic actuator 3, and a first cover plate 4 and a second cover plate 5 respectively covering both sides of the middle frame 1. The middle frame 1 integrates a pump body mechanism 2. In this embodiment, the pump body mechanism 2 is provided with a pump chamber 21 and a first gas channel 22 and a second gas channel 23 communicating with the pump chamber 21. The ultrasonic actuator 3 is installed in the pump chamber 21 of the pump body mechanism 2 and is driven by a high-frequency voltage signal above 20kHz to generate vibration, propelling gas through the first gas channel 22 and the second gas channel 23 to supply oxygen to the aquaculture equipment.

[0033] Specifically, such as Figure 2 and Figure 3 As shown, the middle frame 1 of this embodiment includes a first frame 11 and a second frame 12 that are adapted and spliced ​​together. The first frame 11 and the second frame 12 are detachably connected by bolts, which facilitates the installation and maintenance of internal components. In this embodiment, a first pump body 111 is integrally formed inside the first frame 11, and a second pump body 121 is integrally formed inside the second frame 12. When the first frame 11 and the second frame 12 are spliced ​​and fixed, the first pump body 111 and the second pump body 121 are precisely docked and combined to form a complete pump body mechanism 2, and at the same time, a sealed pump chamber 21 is formed inside, thereby providing space for gas compression and transportation.

[0034] like Figure 2 and Figure 3As shown, in this embodiment, the ultrasonic actuator 3 is sandwiched between the first pump body 111 and the second pump body 121, and divides the pump chamber 21 into two independent chambers, the first chamber 211 and the second chamber 212. Both the first chamber 211 and the second chamber 212 are connected to the first gas channel 22 and the second gas channel 23. External gas can enter the first chamber 211 and the second chamber 212 through the first gas channel 22 or the second gas channel 23, and be output from the second gas channel 23 or the first gas channel 22 under the action of the ultrasonic actuator 3, thereby realizing the supply of oxygen.

[0035] Specifically, in this embodiment, the first gas channel 22 is configured as an inlet channel, and the second gas channel 23 is configured as an outlet channel. When the ultrasonic actuator 3 generates high-frequency vibration under the drive of a high-frequency voltage signal, ultrasonic standing waves are formed in the first chamber 211 and the second chamber 212 due to the vibration. This compresses the chamber space, allowing the first gas channel 22 to draw in gas and using the change in sound pressure to drive the gas flow to the second gas channel 23 for output, thereby achieving oxygen supply. In other embodiments, the second gas channel 23 can also be configured as an inlet channel, and the first gas channel 22 as an outlet channel, achieving the same technical effect, which will not be elaborated here.

[0036] Furthermore, the ultrasonic actuator 33 in this embodiment uses a piezoelectric ceramic sheet or a piezoelectric vibrator, and is configured to be driven by a high-frequency voltage signal above 20kHz during operation. The operating frequency is beyond the range of human hearing, thereby completely eliminating the noise caused by traditional mechanical transmission and effectively improving the user experience.

[0037] like Figure 2 and Figure 3 As shown, to achieve gas inlet and outlet and unidirectional gas delivery, this embodiment provides a first gas channel 22 and a second gas channel 23 on both the first pump body 111 and the second pump body 121, allowing gas delivery to both the first chamber 211 and the second chamber 212 through their respective first gas channels 22 and second gas channels 23. Furthermore, a one-way valve 7 is provided within the second gas channel 23, enabling oxygen delivery to both the first chamber 211 and the second chamber 212 through the sequential opening and closing of the one-way valve 7, thereby achieving continuous oxygen pumping. When the one-way valve 7 is installed in the forward direction, gas can only be output from the chamber to the second gas channel 23; when the one-way valve 7 is installed in the reverse direction, gas can only be input from the second gas channel 23 into either the first chamber 211 or the second chamber 212, ensuring unidirectional gas flow.

[0038] Specifically, when the ultrasonic actuator 3 vibrates under the drive of a high-frequency voltage signal, it alternately changes the pressure at the center of the first chamber 211 and the second chamber 212, such as... Figure 2 and Figure 3As shown, in this embodiment, the first gas channel 22 is configured as an inlet channel and the second gas channel 23 is configured as an outlet channel. At this time, the one-way valve 7 is configured in the second gas channel 23. When the pressure of the first chamber 211 decreases, external gas enters the first chamber 211 through the first gas channel 22 of the first pump body 111. At the same time, the pressure of the second chamber 212 increases, pushing the one-way valve 7 inside it to open and pushing the gas to the second gas channel 23. Conversely, when the pressure of the second chamber 212 decreases, external gas enters the second chamber 212 through the first gas channel 22 on the second pump body 121. The pressure of the first chamber 211 increases, and the one-way valve 7 inside it opens, pushing the gas to the second gas channel 23 for output.

[0039] In another embodiment, the first gas channel 22 is configured as an outlet channel, and the second gas channel 23 is configured as an inlet channel. In this case, the one-way valve 7 is configured in reverse in the second gas channel 23. When the pressure in the first chamber 211 decreases, the one-way valve 7 inside it opens, and external gas enters the first chamber 211 through the second gas channel 23 of the first pump body 111. At the same time, the pressure in the second chamber 212 increases and the one-way valve 7 inside it closes, so that the gas is pushed to the first gas channel 22 for output. Conversely, when the pressure in the second chamber 212 decreases, the one-way valve 7 inside it opens, and external gas enters the second chamber 212 through the second gas channel 23 of the second pump body 121. At the same time, the pressure in the first chamber 211 increases and the one-way valve 7 inside it closes, so that the gas is pushed to the first gas channel 22 for output.

[0040] In this embodiment, two alternately operating one-way valves 7 are installed in the first chamber 211 and the second chamber 212. When the ultrasonic actuator 3 vibrates, the two one-way valves 7 can alternately open and close in accordance with the pressure changes in the first chamber 211 and the second chamber 212, thereby achieving continuous and stable gas output. Compared with traditional mechanical reciprocating motion, the vibration is small and the noise is low, which can effectively improve the user experience.

[0041] Furthermore, in this embodiment, both one-way valves 7 are positioned directly opposite the antinodes of the ultrasonic standing wave, where the sound pressure variation is greatest, thus maximizing gas propulsion efficiency. Additionally, the ends of the two second gas channels 23 in this embodiment are connected and extend together outside the middle frame 1, allowing the gas output from the two chambers to be collected and discharged through the same channel, or input through the same channel, achieving centralized delivery of oxygen-enhancing flow.

[0042] like Figure 2As shown, in this embodiment, the first cover plate 4 and the second cover plate 5 are respectively installed on the two side end faces of the middle frame 1. The first cover plate 4 and the second cover plate 5 are the lower cover plate and the upper cover plate, respectively. The upper and lower cover plates are independent of the middle frame 1 when the mold is removed, and can be installed onto the middle frame 1 by adhesive, ultrasonication, or tight fitting. The surface of the first cover plate 4 in this embodiment has several ventilation holes 6, which communicate with the internal space of the middle frame 1, thereby connecting with the first gas channel 22 of the pump body mechanism 2, providing a channel for gas entry. In other embodiments, the ventilation holes 6 can also be provided on the surface of the second cover plate 5 or on the middle frame 1, achieving the same technical effect.

[0043] Furthermore, to ensure the cleanliness of the gas entering the chamber, the surface of the first cover plate 4 with vent holes 6 is recessed inward to form a filter chamber 41. A filter cotton 9 is detachably installed inside the filter chamber 41, and the filter cotton 9 completely covers the vent holes 6, filtering dust and impurities in the air to prevent them from entering the pump chamber 21 and affecting the operation of the ultrasonic actuator 3 and the one-way valve 7 or contaminating the water. Simultaneously, multiple evenly distributed support blocks 411 are provided at the bottom plane of the filter chamber 41. The support blocks 411 abut against the bottom surface of the filter cotton 9, creating an air intake gap between the filter cotton 9 and the bottom of the chamber. This ensures that the incoming gas can pass evenly through the filter cotton 9 for filtration, improving the filtration effect and extending the service life of the filter cotton 9. In addition, it allows gas to pass smoothly, preventing the filter cotton 9 from sticking to the bottom of the chamber and obstructing the air intake. Furthermore, when the filter cotton 9 is severely clogged, it can be removed from the filter chamber 41 and replaced by disassembling the first cover plate 4, thus ensuring the filtration effect and making replacement convenient.

[0044] like Figure 2 and Figure 3 As shown, in order to enable the ultrasonic actuator 3 to operate, a drive board 8 is provided inside the middle frame 1 of this embodiment. The drive board 8 is fixed to the first frame 11 or the second frame 12 by bolts. The ultrasonic actuator 3 is electrically connected to the drive board 8, thereby receiving a high-frequency voltage drive signal from the drive board 8. The drive board 8 of this embodiment is provided with a power supply interface 81 for power supply. The power supply interface 81 of this embodiment adopts a USB interface, which can be connected to a power adapter, power bank or other devices via a USB data cable for power supply, making the application scenarios more flexible and adaptable.

[0045] Furthermore, in this embodiment, a power supply battery is also installed inside the cavity formed by the first cover plate 4, the second cover plate 5, and the middle frame 1. The power supply battery is electrically connected to the drive board 8, allowing the oxygen pump of this embodiment to power the drive board 8 via the power supply battery. This eliminates the need for an external power source, enabling the ultrasonic actuator 3 to operate normally and thus delivering oxygen. This facilitates outdoor use in areas without power, expanding the applicability of this embodiment. Additionally, the power supply battery in this embodiment can be connected to the power supply interface 81 via the drive board 8, allowing the power supply interface 81 to charge the battery when an external power source is connected, facilitating subsequent use.

[0046] Example 2:

[0047] like Figures 4 to 6 As shown, the difference from Embodiment 1 is that Embodiment 2 has two independent pump mechanisms 2 within the middle frame 1. In other embodiments, the pump mechanisms 2 can also be set to three or more. In this embodiment, the two pump mechanisms 2 are arranged side-by-side and have the same structure. Each pump mechanism 2 has an independent pump chamber 21, an ultrasonic actuator 3, a first gas channel 22, and a second gas channel 23, allowing for independent gas delivery. By setting up dual pump mechanisms 2, this embodiment can supply oxygen to different devices through the two pump mechanisms 2, meeting diverse oxygenation needs of customers; alternatively, the two pump mechanisms 2 can further increase the gas output of the oxygenation pump to meet the oxygenation needs of larger aquariums. Furthermore, the ultrasonic actuators 3 of the two pump mechanisms 2 in this embodiment can operate independently at their respective resonant frequencies, thereby achieving the highest mechanical energy conversion efficiency for each ultrasonic actuator 3, thus improving working efficiency.

[0048] In addition, such as Figures 4 to 6 As shown, to facilitate adjustment of the oxygen supply, a regulator 82 is electrically connected to the drive board 8 in this embodiment. The user can flexibly adjust the power of the ultrasonic actuator 3 via the regulator 82, thereby adjusting the oxygen output. Specifically, the regulator 82 in this embodiment is a power regulator, which controls the power of the ultrasonic actuator 3 by adjusting the voltage, thus adjusting the oxygen output. In this embodiment, an adjustment knob 83 is provided on the first cover plate 4. The bottom end of the adjustment knob 83 passes through the first cover plate 4 and connects to the regulator 82, allowing the user to adjust the output power of the regulator 82 by rotating the adjustment knob 83, thereby adjusting the power of the ultrasonic actuator 3 and adjusting the oxygen output. The adjustment method is convenient. In other embodiments, the adjustment knob 83 can also be installed on the second cover plate 5 or the middle frame 1 depending on the position of the regulator 82, achieving the same technical effect.

[0049] In summary, this embodiment uses the high-frequency vibration of the ultrasonic actuator 3 above 20kHz to generate sound pressure to drive gas flow, eliminating the mechanical transmission structure of traditional aerator pumps, effectively reducing noise and vibration during aeration, and eliminating mechanical friction loss, resulting in higher energy conversion efficiency and thus effectively reducing operating energy consumption; at the same time, the modular frame 1 makes the equipment easy to install and maintain, flexible in application scenarios, and widely applicable to various aquaculture scenarios.

[0050] The embodiments described above are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and modifications made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
