[0004] The microbubble generation modules in related technologies have the following drawbacks: These modules primarily consist of a first mesh and a second mesh, generating microbubbles through a specific structure. However, this design mainly focuses on bubble generation while lacking comprehensive water filtration. Utility Model Content

[0005] To overcome the above-mentioned technical problems, this application provides a micro / nano bubble generation device.

[0006] The micro / nano bubble generation device provided in this application adopts the following technical solution:

[0007] A micro-nano bubble generating device includes a shell mechanism and a multi-stage filtration mechanism. The shell mechanism is used to connect to a faucet water purifier. The shell mechanism has a cavity inside, with both ends of the cavity being open. The multi-stage filtration mechanism is disposed inside the cavity.

[0008] By adopting the above technical solution, the multi-stage filtration mechanism can efficiently generate microbubble water molecules smaller than 1μm. These bubbles can penetrate deep into skin pores to achieve deep cleansing and hydration, making them particularly suitable for beauty and skincare. The entire device has a simple structure, with stable connections between components and a relatively simple manufacturing process, reducing production costs and facilitating large-scale production and market promotion. The multi-stage filtration mechanism ensures the uniformity and stability of the bubbles, improving the cleaning effect and user experience. This makes the device suitable not only for home beauty care but also for widespread application in kitchen scenarios, such as washing fruits and vegetables. The micro-nano bubble generating device of this application integrates a shell structure and a multi-stage filtration mechanism, achieving the dual functions of multi-stage water filtration and microbubble generation. The multi-stage filtration mechanism can efficiently remove impurities and contaminants from the water, while the microbubble generation part can generate microbubbles in the filtered water. The diameter of these microbubbles reaches the micro-nano level, improving the water cleaning effect and user experience.

[0009] Optionally, the multi-stage filtration mechanism includes a primary filtration assembly, a secondary filtration assembly, and a final filtration assembly; the primary filtration assembly includes a primary filter plate and a support rod, one end of which is fixed to the primary filter plate; the secondary filtration assembly has a through hole through which the support rod passes; the end of the support rod contacts one side of the final filtration assembly, and a limiting ring is also provided inside the housing mechanism to abut against the other side of the final filtration assembly.

[0010] By adopting the above technical solution, the multi-stage filtration mechanism includes a primary filtration component, a secondary filtration component, and a terminal filtration component. The primary filtration component includes a primary filter plate and a support rod, with one end of the support rod fixed to the primary filter plate. The secondary filtration component has a through-hole through which the support rod passes, and the end of the support rod contacts one side of the terminal filtration component. A limiting ring is also provided inside the outer casing to abut against the other side of the terminal filtration component. This prevents positional displacement caused by vibration or water flow impact, ensuring the continuity and stability of the filtration process and improving filtration efficiency and effect. Simultaneously, the limiting ring ensures the stability of the terminal filtration component, preventing it from moving under the action of water flow, further enhancing the reliability and durability of the entire device.

[0011] Optionally, the inner wall of the housing mechanism is provided with a first annular groove, the outer wall of the primary filter plate is grounded to the inner wall of the first annular groove, and the primary filter plate is fixedly connected to the housing mechanism.

[0012] By adopting the above technical solution, the primary filter plate cooperates with the first annular groove on the inner side of the cavity, ensuring that the primary filter plate is firmly installed inside the outer shell mechanism, thus enhancing the overall stability of the device. Simultaneously, the fixed connection between the primary filter plate and the outer shell mechanism makes the water flow more uniform as it passes through the primary filter plate, improving filtration efficiency and water purification effect.

[0013] Optionally, the primary filter plate has multiple through-hole water inlet channels; the secondary filter assembly includes a secondary filter plate, the through-hole is located on the secondary filter plate, the secondary filter plate has multiple filter holes, the water inlet channels correspond one-to-one with the filter holes, and the axis of the water inlet channels is aligned with the axis of the filter holes.

[0014] By adopting the above technical solution, it is possible to ensure that each water inlet channel is precisely aligned with the corresponding filter hole when the water flows through the primary filter plate and the secondary filter plate, thereby ensuring smooth water flow and improving filtration efficiency. Secondly, the alignment of the water inlet channel with the filter hole axis can reduce water turbulence and resistance, making the water flow more stable, which helps to form uniform small bubbles, improve cleaning effect and user experience.

[0015] Optionally, a second annular groove is formed on the inner wall of the cavity, the diameter of the second annular groove being smaller than the diameter of the first annular groove, and one side of the secondary filter plate abutting against the bottom of the second annular groove; a clamping block is fixedly provided on the support rod, and the clamping block abutting against the other side of the secondary filter plate.

[0016] By adopting the above technical solution, firstly, it positions the secondary filter plate, preventing it from shifting under the impact of water flow and improving the filtration effect; secondly, the diameter of the second annular groove makes the secondary filter plate and the first annular groove form a stepped structure, increasing the complexity of the water flow path and helping to further improve the filtration efficiency; thirdly, the clamping block enhances the stability of the secondary filter plate, avoiding loosening caused by external vibration or water flow impact, and improving the reliability and service life of the entire device.

[0017] Optionally, the water inlet channel includes an inlet hole and an outlet hole that are interconnected. The inlet hole is shaped like a frustum, and the outlet hole is shaped like a cylinder. The diameter of the end of the inlet hole away from the outlet hole is larger than the diameter of the outlet hole, and the diameter of the end of the inlet hole closer to the outlet hole is the same as the diameter of the outlet hole.

[0018] By adopting the above technical solution, the water inlet is shaped like a frustum, which gradually reduces the cross-section of the flow channel as water enters, thereby accelerating the water flow velocity, enhancing the water flow impact force, and improving the efficiency of water molecule breaking down, thus forming more microbubbles. Meanwhile, the water outlet is shaped like a cylinder, maintaining stable water flow, ensuring uniform bubble size, and improving cleaning effect and user experience.

[0019] Optionally, the filter hole is shaped like a frustum, and the diameter of the filter hole at the end near the water inlet channel is larger than the diameter of the water outlet.

[0020] By adopting the above technical solution, the filter hole is shaped like a frustum, and the diameter of the end near the water inlet is larger than the diameter of the water outlet. This creates a pressure difference when the water flows through the filter hole, which helps to generate finer and more uniform microbubbles. This not only improves the cleaning effect but also enhances the user experience.

[0021] Optionally, the outer casing includes a mounting cylinder and an inner cylinder, both ends of the mounting cylinder being open, and the inner cylinder being disposed inside the mounting cylinder; a first gap is provided between the primary filter plate and the secondary filter plate, and the area between the primary filter plate, the secondary filter plate and the inner cylinder is defined as the air intake area; a second gap is provided between the outer side wall of the inner cylinder and the inner side wall of the mounting cylinder, and a through air inlet is provided on the mounting cylinder, one end of the air inlet being connected to the air intake area.

[0022] By adopting the above technical solution, firstly, a stable air intake area can be formed between the primary filter plate and the secondary filter plate, ensuring that the gas can be evenly distributed and improving the bubble generation efficiency; secondly, by setting a second gap between the mounting cylinder and the inner cylinder and opening an air intake on the outside, outside air can smoothly enter the air intake area, further enhancing the bubble generation capacity; thirdly, the structure is reasonable, easy to install, simple to maintain, and highly adaptable, and can be widely used in various occasions that require microbubble generation.

[0023] Optionally, the secondary filter assembly further includes a convex ring, which is fixed to the surface of the secondary filter plate and located in the air intake area. The convex ring corresponds one-to-one with the filter holes, and the end of the filter hole facing the primary filter assembly passes through the convex ring.

[0024] By adopting the above technical solutions, firstly, the structural stability of the secondary filter plate can be enhanced, ensuring the positional accuracy of the filter holes and thus improving the filtration effect; secondly, the convex ring makes the filter holes more precisely aligned with the water inlet channel of the primary filter component, reducing water flow resistance and improving water flow efficiency; and thirdly, the presence of the convex ring can increase the effective area of ​​the air intake zone, promoting the entry of more air, forming more microbubbles, and improving the efficiency and quality of bubble generation.

[0025] Optionally, the outer wall of the mounting cylinder is provided with external threads.

[0026] By adopting the above technical solution, the outer wall of the mounting cylinder is provided with external threads, which allows the micro-nano bubble generating device to be easily and quickly connected to a faucet water purifier or other equipment, thereby enhancing the versatility and ease of installation of the device.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0036] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0037] The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. Unless otherwise defined, the technical or scientific terms used in this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

[0038] This application discloses a micro / nano bubble generation device. (Refer to...) Figure 1 and Figure 2 The micro-nano bubble generating device includes a shell structure and a multi-stage filtration mechanism. The shell structure is used to connect to a faucet water purifier, and its interior has a cavity 3 with openings at both ends. The multi-stage filtration mechanism is located inside the cavity 3. This structure enables the micro-nano bubble generating device to efficiently generate microbubbles with diameters reaching the micro-nano level, effectively penetrating into the pores of skin and the tiny crevices on the surface of fruits and vegetables, improving cleaning effectiveness and user experience.

[0039] Continue to refer to Figure 1 and Figure 2 Specifically, the outer casing includes a mounting cylinder 1 and an inner cylinder 2. Both ends of the mounting cylinder 1 are open, and the inner cylinder 2 is disposed inside the mounting cylinder 1. Specifically, an annular flange 24 is integrally formed on the outer wall of one end of the inner cylinder 2, and an annular groove 11 is formed on the inner wall of one end of the mounting cylinder 1. The outer wall of the annular flange 24 abuts against the inner wall of the annular groove 11, thereby fixing the inner cylinder 2 inside the mounting cylinder 1. The two ends of the inner cylinder 2 are aligned with the two ends of the mounting cylinder 1, increasing the overall aesthetic appeal.

[0040] Reference Figure 1The mounting cylinder 1 is provided with symmetrical clamping grooves 12 on both sides, which makes it easier for workers to clamp the mounting cylinder 1 with a wrench or other tools, increasing the convenience of workers to install and remove the mounting cylinder.

[0041] Reference Figure 2 and Figure 3 The multi-stage filtration mechanism includes a primary filter assembly 5, a secondary filter assembly 6, and a terminal filter assembly 7 arranged sequentially from the outside to the inside.

[0042] Reference Figure 2 and Figure 3 The primary filter assembly 5 includes a primary filter plate 51 and multiple support rods 52. The primary filter plate 51 is disc-shaped, and a first annular groove 22 is formed on the inner wall of the cavity 3. The outer wall of the primary filter plate 51 is connected to the inner wall of the first annular groove 22. The primary filter plate 51 is fixedly connected to the inner cylinder 2, and the outer surface of the primary filter plate 51 is flush with the end of the inner cylinder 2, which increases the overall aesthetics. One end of each support rod 52 is integrally formed with the primary filter plate 51.

[0043] Continue to refer to Figure 2 and Figure 3 The secondary filter assembly 6 includes a secondary filter plate 61 with multiple through holes 63. Each support rod 52 corresponds to one of the through holes 63 and passes through the through hole 63. The end of each support rod 52 facing the terminal filter assembly 7 is in contact with one side of the terminal filter assembly 7. A limiting ring 25 is integrally formed inside the inner cylinder 2 near the end of the terminal filter assembly 7. The limiting ring 25 is used to abut against the other side of the terminal filter assembly 7, thereby fixing the primary filter assembly 5 and the terminal filter assembly 7 inside the cavity 3 of the inner cylinder 2.

[0044] Continue to refer to Figure 2 and Figure 3 The primary filter plate 51 has multiple through-holes 53, each including interconnected inlet holes 531 and outlet holes 532. The inlet holes 531 are frustum-shaped, and the outlet holes 532 are cylindrical. The diameter of the end of the inlet hole 531 furthest from the outlet hole 532 is larger than the diameter of the outlet hole 532, while the diameter of the end of the inlet hole 531 closest to the outlet hole 532 is the same as the diameter of the outlet hole 532. As water flows through the inlet holes 531, the velocity gradually increases, which is beneficial for bubble generation.

[0045] Continue to refer to Figure 2 and Figure 3The secondary filter plate 61 has multiple filter holes 64, each shaped like a frustum. The diameter of the filter hole 64 near the water inlet channel 53 is larger than the diameter of the water outlet hole 532. The water inlet channel 53 corresponds one-to-one with the filter holes 64, and the axis of the water inlet channel 53 is aligned with the axis of the filter hole 64. This ensures that when water flows through the filter holes 64, it not only ensures smooth flow during the primary and secondary filtration processes but also effectively prevents water from entering the air intake area 4. This guarantees the quality of the bubbles during the refining process and further improves the generation efficiency and purity of the microbubbles.

[0046] Continue to refer to Figure 2 and Figure 3 Specifically, the secondary filter assembly 6 also includes multiple convex rings 62, which are fixed to the surface of the secondary filter plate 61 and located within the air intake area 4. Each convex ring 62 corresponds to a filter hole 64, with the end of the filter hole 64 facing the primary filter assembly 5 passing through the convex ring 62. The convex rings 62 enhance the turbulence effect of the water flow, further refine air bubbles, and improve the cleaning effect.

[0047] Continue to refer to Figure 2 and Figure 3 A first gap 9 is provided between the primary filter plate 51 and the secondary filter plate 61, defining the area between the primary filter plate 51, the secondary filter plate 61, and the inner cylinder 2 as the air intake area 4. A second gap 10 is provided between the outer wall of the inner cylinder 2 and the inner wall of the mounting cylinder 1, with one end of the second gap 10 communicating with the atmosphere. Multiple through-holes 21 are evenly arranged circumferentially in the inner cylinder 2. This helps ensure that the air-water mixture is generated uniformly throughout the entire inner cylinder 2, thereby improving the generation efficiency and uniformity of microbubbles. One end of each air intake 21 is connected to the air intake area 4, and the other end of each air intake 21 is connected to the second gap 10. This allows external air to smoothly enter the air intake area 4 inside the device and mix with the water flow to form microbubbles. Due to their small size and large number, these microbubbles can more effectively penetrate into the pores of skin and the tiny crevices on the surface of fruits and vegetables, thereby improving the cleaning effect and user experience.

[0048] Reference Figure 2 The inner wall of the cavity 3 is also provided with a second annular groove 23, the diameter of which is smaller than that of the first annular groove 22. One side of the secondary filter plate 61 abuts against the bottom of the second annular groove 23. A clamping block 54 is fixedly installed on the support rod 52, and the clamping block 54 abuts against the other side of the secondary filter plate 61, thereby fixing the secondary filter assembly 6 inside the cavity 3 of the inner cylinder 2. This ensures that all components are tightly connected and prevents water leakage. For example, the first annular groove 22 and the second annular groove 23 can be made of rubber sealing rings to improve the sealing effect; the clamping block 54 can be made of aluminum alloy, which is lightweight and has high strength.

[0049] Reference Figure 1 and Figure 2 Specifically, the outer wall of the mounting cylinder 1 is provided with external threads 13 to facilitate connection with the faucet water purifier. For example, the external threads 13 can be made of nickel-plated copper, which has good rust resistance.

[0050] Reference Figure 2 and Figure 3 The terminal filter assembly 7 can further filter out fine impurities and improve water quality. In this embodiment, the terminal filter assembly 7 uses a stainless steel filter screen, which has high filtration efficiency and long service life.

[0051] The implementation principle of the above embodiments is as follows: the multi-stage filtration mechanism can efficiently generate microbubble water molecules smaller than 1μm. These bubbles can penetrate deep into skin pores to achieve deep cleansing and hydration, making them particularly suitable for beauty and skincare. The entire device has a simple structure, with stable connections between components, and a relatively simple manufacturing process, reducing production costs and facilitating large-scale production and market promotion. The multi-stage filtration mechanism ensures the uniformity and stability of the bubbles, improving the cleaning effect and user experience, making the device suitable not only for home beauty care but also for widespread application in kitchen scenarios, such as washing fruits and vegetables. The micro-nano bubble generating device of this application integrates a shell structure and a multi-stage filtration mechanism, achieving the dual functions of multi-stage filtration and microbubble generation. The multi-stage filtration mechanism can efficiently remove impurities and pollutants from the water, while the microbubble generation part can generate microbubbles in the filtered water, improving the water's cleaning effect and user experience.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
