Description

Technical Field

[0001] This invention relates to the field of ultrasonic humidification technology, and more specifically, to an ultrasonic humidifier for the maintenance of waterproof boards. Background Technology

[0002] Waterproof and environmentally friendly boards require hardening and curing treatment during production to ensure their mechanical properties and stability. Currently, the industry commonly uses natural air drying, where the boards are laid flat on the ground and hardened by the humidity and temperature of the natural environment. However, this traditional method has many drawbacks: firstly, the hardening cycle is long, typically requiring 6-9 days to reach the required hardness, severely impacting production efficiency; secondly, the temperature and humidity of the natural environment are difficult to control, leading to problems such as cracks, efflorescence, and hollow areas on the board surface, and insufficient surface tensile strength, resulting in poor product quality stability.

[0003] To address the aforementioned issues, a few companies have attempted to use artificially regulated temperature and humidity for curing. This involves constructing simple, enclosed spaces and using ultrasonic humidifiers to simulate a relatively stable curing environment, thereby shortening the curing cycle and improving product quality. However, existing ultrasonic humidifiers are mostly general-purpose devices, lacking specific designs for the curing of waterproof and environmentally friendly boards. They cannot precisely control the humidity according to the specific needs of the boards, and they are difficult to adapt to different board stacking methods to ensure uniform humidification. Therefore, they cannot meet the high-efficiency curing requirements of waterproof and environmentally friendly boards. Thus, there is an urgent need for an ultrasonic humidifier specifically designed for the curing of waterproof boards to solve these problems. Summary of the Invention

The first partition, the second partition, and the sealing cover are all fixedly connected. An ultrasonic atomizing plate is provided on the top of the horizontal plate. A PCB board is fixedly connected to the bottom inner wall of the box body. The PCB board is located directly below the first partition. A through groove is opened on one side of the second partition. A settling hopper is provided inside the box body. The settling hopper is located directly below the ultrasonic atomizing plate. A mist delivery cylinder is fixedly connected to the top outer wall of the horizontal plate. The mist delivery cylinder covers the top of the ultrasonic atomizing plate. A protective shell is fixedly connected to the circumferential outer wall of the mist delivery cylinder. Spray pipes with equal distances are rotatably connected to the circumferential outer wall of the protective shell. The inside of the mist delivery cylinder is equipped with a blowing component for increasing the airflow rate of the mist.

[0006] Preferably, the blowing assembly includes a motor fixedly connected to the inner wall of one side of the housing, a second rotating column fixedly connected to the output end of the motor, a second helical gear fixedly connected to the outer circumference of the second rotating column, a first helical gear meshing with the outer circumference of the second helical gear, a reinforcing rod fixedly connected to the inner circumference of the mist delivery cylinder, a bearing seat fixedly connected to one end of the reinforcing rod, a first rotating column fixedly connected to the inner circumference of the bearing seat, the first helical gear fixedly connected to the outer circumference of the first rotating column, a bushing fixedly connected to the outer circumference of the first rotating column, and fan blades evenly spaced and circularly distributed fixedly connected to the outer circumference of the bushing.

[0007] Preferably, the fan blade includes a blade, and the arc-shaped edge of the blade is fixedly connected with equally spaced tooth blocks. The cross-section of the tooth blocks is an isosceles triangle. A first protrusion, a guide strip, and a second protrusion are provided on one outer wall of the blade. The guide strip is located in the middle of the first protrusion and the second protrusion, and the cross-section of the guide strip is wavy.

[0008] Preferably, the first bump is closer to the bushing than the second bump, and the distribution density of the second bump is lower than that of the first bump.

[0009] Preferably, the first partition is inclined inside the box, and the top of the first partition is provided with equally spaced arc-shaped grooves.

[0010] Preferably, the settling hopper includes a lower hopper section, a constricting section, and an upper hopper section. The cross-sections of the lower hopper section and the upper hopper section are both semi-circular. The inner diameter of the constricting section is smaller than the diameters of the lower hopper section and the upper hopper section. The inner circumferential wall of the lower hopper section is provided with equally spaced circularly distributed water inlet grooves.

[0011] Preferably, a first worm is fixedly connected to the outer circumference of the second rotating column, a first worm gear is meshed with the outer circumference of the first worm, a third rotating column is fixedly connected to the inner circumference of the first worm gear, one end of the third rotating column is rotatably connected to the cross plate, and the other end of the third rotating column extends into the interior of the protective shell.

[0012] Preferably, a second worm gear is fixedly connected to the outer circumference of the third rotating column located inside the protective shell, and a second worm wheel is fixedly connected to the outer circumference of the spray pipe. The second worm wheel meshes with the second worm gear, and the other end of the spray pipe is rotatably connected to the mist delivery cylinder.

[0013] Preferably, a guide groove is provided at one end of the spray pipe near the mist delivery cylinder, and a mist outlet groove is provided at the other end of the spray pipe, with the mist outlet groove connected to the guide groove.

[0014] Preferably, the cross-section of the mist outlet groove is wavy, and the inner diameter of the mist outlet groove gradually decreases along the vertical downward direction of the mist delivery cylinder inside the spray pipe.

[0015] The beneficial effects of this invention are: This invention provides an ultrasonic humidifier for the maintenance of waterproof boards. The arc-shaped groove on the first partition effectively creates multi-stage sedimentation. The slow flow and backflow of water within the arc-shaped groove allow impurities and particulate matter in the water to gradually settle under gravity, reducing impurities adhering to the surface of the ultrasonic atomizing plate. This ensures the stability of the atomization effect, extends the service life of the atomizing plate, and prevents impurities from being ejected with the mist and affecting the quality of board maintenance. Simultaneously, the special structure of the settling hopper further optimizes water quality and supply stability. The upper, constricted, and lower sections of the settling hopper form a unique buffer space. The semi-circular cross-sections of the upper and lower sections expand the water flow area, while the smaller inner diameter of the constricted section slows the water flow, allowing the water to settle fully within the hopper, further separating any remaining fine impurities. Combined with the water inlet groove on the inner wall of the lower hopper, this achieves uniform water inflow and stable output, preventing unstable water levels at the ultrasonic atomizing plate due to water flow fluctuations, and ensuring the continuity and uniformity of the atomization process.

[0016] This invention provides an ultrasonic humidifier for the maintenance of waterproof boards. Through a specially designed blowing assembly, after the ultrasonic atomizing plate atomizes water, the mist enters the mist delivery cylinder. Simultaneously, the blowing assembly inside the mist delivery cylinder operates, with a motor driving a second rotating column to rotate. The meshing of a second helical gear with a first helical gear drives the first rotating column to rotate, causing the fan blades on the bushing to rotate at high speed. Because the blades' front surface and sides are respectively equipped with a first protrusion, a guide strip, a second protrusion, and a toothed block, a three-stage synergistic turbulence mechanism can achieve efficient atomization and diffusion of the mist droplets generated by the ultrasonic atomizing plate. Specifically, this is achieved through the first protrusion on the blade surface... The first and second protrusions first block and divert the incoming mist flow on a large scale, generating radial velocity components and initially spreading the concentrated mist. Subsequently, the wave-shaped guide strip in the middle causes the airflow to generate periodic fluctuations and small-scale vortices, promoting the collision, mixing and breaking of mist droplets into finer particles. Finally, the isosceles triangular teeth on the trailing edge of the blades form a strong shearing effect and periodic vortex street at the outlet, performing final shearing and tearing of the mist flow. This allows the blown mist to achieve a large-scale, uniform and delicate dispersion effect while maintaining wind speed, ensuring that the fine mist can better penetrate into the gaps between the stacked waterproof boards.

[0017] This invention provides an ultrasonic humidifier for the maintenance of waterproof boards. Through the design of spray pipes, mist outlets, and guide channels, a second rotating column is driven by a motor to rotate. Simultaneously, the second rotating column drives a first worm gear on its outer wall to rotate. Through the meshing between the first worm gear and a first worm wheel, a third rotating column is driven to rotate. When the third rotating column rotates, its extension into the protective shell drives the second worm gear fixed to the outer wall to rotate synchronously. Utilizing the meshing transmission between the second worm gear and the second worm wheel fixed to the outer circumference of the spray pipe, the equally spaced spray pipes are driven to rotate synchronously. During the rotation of the spray pipes, the guide channel near the mist outlet smoothly guides the mist from the mist outlet into the pipe, and then through the wavy mist outlet connected to the guide channel at the other end. The mist is sprayed out in a spiral pattern. The rotating spiral spray of the spray pipe enhances the mist pressure, allowing the mist to travel a longer path after being sprayed out, and achieves uniform spraying with no dead angles. This ensures that both ends of the waterproof board, near and far from the device, can effectively contact the mist droplets. This solves the problems of limited spray range and difficulty in covering the far and inner sides of stacked boards by traditional general-purpose humidifiers. After the mist is blown out, it gradually sinks, which can easily cause the waterproof board stacked on top to receive less mist than the waterproof board stacked on the bottom. At this time, the design of the mist outlet groove with the inner diameter gradually decreasing along the vertical downward direction of the mist delivery tube can specifically compensate for the impact of the mist sinking, avoiding the situation where the waterproof board at the bottom is too wet while the board at the top is not wet enough.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0029] Please see Figure 1 - Figure 8 An ultrasonic humidifier for the maintenance of waterproof boards includes a housing 1, a water inlet 3 for filling the interior with water is provided on the top of the housing 1, a sealing cover 4 for sealing is provided on the top of the water inlet 3, and a control panel 2 is fixedly connected to one side of the outer wall of the housing 1. Inside the housing 1, a first partition 8, a second partition 12, and a horizontal plate 14 are fixedly connected. The first partition 8, the second partition 12, and the sealing cover 4 are all fixedly connected. An ultrasonic atomizing plate 15 is installed on the top of the horizontal plate 14. A PCB board 10 is fixedly connected to the bottom inner wall of the housing 1, located directly below the first partition 8. A through slot 13 is opened on one side of the second partition 12. A settling hopper 11 is installed inside the housing 1, located below the ultrasonic atomizing plate 15. Directly below 5, a mist delivery cylinder 6 is fixedly connected to the top outer wall of the horizontal plate 14. The mist delivery cylinder 6 covers the top of the ultrasonic atomizing plate 15. A protective shell 5 is fixedly connected to the outer circumference of the mist delivery cylinder 6. Spray pipes 7 are rotatably connected to the outer circumference of the protective shell 5. The ultrasonic atomizing plate 15 will convert the clean water it comes into contact with into fine and uniform mist droplets, providing suitable atomized water vapor for the maintenance of waterproof boards, effectively avoiding the quality problems of boards caused by uneven water supply in traditional maintenance. The mist delivery cylinder 6 is equipped with a blowing component to increase the airflow rate of the mist.

[0030] Furthermore, the blower assembly includes a motor 24 fixedly connected to the inner wall of one side of the housing 1. A second rotating column 23 is fixedly connected to the output end of the motor 24. A second helical gear 22 is fixedly connected to the outer circumference of the second rotating column 23. A first helical gear 18 meshes with the outer circumference of the second helical gear 22. A reinforcing rod 21 is fixedly connected to the inner circumference of the mist delivery cylinder 6. A bearing seat 17 is fixedly connected to one end of the reinforcing rod 21. A first rotating column 16 is fixedly connected to the inner circumference of the bearing seat 17. The first helical gear 18 is fixedly connected to the outer circumference of the first rotating column 16. A bushing 20 is fixedly connected to the outer circumference of a rotating column 16. A fan blade 19, which is distributed in a circular pattern at equal intervals, is fixedly connected to the outer circumference of the bushing 20. When the ultrasonic atomizing plate 15 atomizes the water, the mist enters the mist delivery cylinder 6. At this time, the blowing assembly in the mist delivery cylinder 6 works synchronously. The motor 24 drives the second rotating column 23 to rotate. Through the meshing of the second helical gear 22 and the first helical gear 18, the first rotating column 16 is driven to rotate, causing the fan blade 19 on the bushing 20 to rotate at high speed. This provides effective kinetic energy to the mist, effectively increasing its delivery distance.

[0031] Furthermore, the fan blade 19 includes a blade 1901, with equally spaced toothed blocks 1903 fixedly connected to the arc-shaped edge of the blade 1901. The cross-section of the toothed blocks 1903 is an isosceles triangle. A first protrusion 1902, a guide strip 1904, and a second protrusion 1905 are provided on one outer wall of the blade 1901. The guide strip 1904 is located in the middle of the first protrusion 1902 and the second protrusion 1905, and its cross-section is wavy. Since the first protrusion 1902, the guide strip 1904, the second protrusion 1905, and the toothed blocks 1903 are respectively provided on the fog-facing surface and the side of the blade 1901, efficient atomization and diffusion of the droplets generated by the ultrasonic atomizing plate 15 can be achieved through a three-stage synergistic turbulence mechanism. Specifically, the first protrusion 1902 and the second protrusion 1905 on the surface of the blade 1901 first block and divert the incoming mist flow on a large scale, generating a radial velocity component and initially spreading the concentrated mist. Subsequently, the wave-shaped guide strip 1904 in the middle causes the airflow to generate periodic fluctuations and small-scale vortices, promoting the collision, mixing and breaking of mist droplets into finer particles. Finally, the isosceles triangular tooth block 1903 on the trailing edge of the blade 1901 forms a strong shearing effect and periodic vortex street at the exit, performing final shearing and tearing of the mist flow. This allows the blown mist to achieve a large-scale, uniform and delicate dispersion effect while maintaining wind speed, ensuring that the fine mist can better penetrate into the gaps between the stacked waterproof boards.

[0032] Furthermore, the first protrusion 1902 is closer to the bushing 20 than the second protrusion 1905, and the distribution density of the second protrusion 1905 is less than that of the first protrusion 1902. Through the "positional differentiation" and "density differentiation" design of the first protrusion 1902 and the second protrusion 1905, a gradient turbulence mechanism from the inside to the outside is formed, which not only ensures the stability of the flow velocity of the mist, but also gradually disperses and homogenizes the concentrated mist, ultimately achieving fine mist with a wide range of diffusion, which is suitable for the gap penetration and full surface coverage requirements of stacked waterproof boards.

[0033] Furthermore, the first partition 8 is inclinedly set inside the box 1, and the top of the first partition 8 is provided with equally spaced arc-shaped grooves 9. Through the arc-shaped grooves 9 on the first partition 8, multi-stage sedimentation can be effectively formed. By utilizing the slow flow and backflow of water in the arc-shaped grooves 9, impurities and particles in the water gradually settle under the action of gravity, reducing the adhesion of impurities to the surface of the ultrasonic atomizing plate 15. This not only ensures the stability of the atomization effect and extends the service life of the atomizing plate, but also prevents impurities from being sprayed out with the mist and affecting the quality of board maintenance.

[0034] Furthermore, the settling hopper 11 includes a lower hopper section 1102, a constriction section 1103, and an upper hopper section 1104. Both the lower hopper section 1102 and the upper hopper section 1104 have semi-circular cross-sections. The inner diameter of the constriction section 1103 is smaller than the diameters of the lower hopper section 1102 and the upper hopper section 1104. The inner circumference of the lower hopper section 1102 is provided with equally spaced, circularly distributed water inlet grooves 1101. The special structure of the settling hopper 11 further optimizes water quality and water supply stability. The upper hopper section 1104, the constriction section 1103, and the lower hopper section 1104 of the settling hopper 11... 102 forms a unique buffer space. The upper bucket 1104 and lower bucket 1102, with a semi-circular cross-section, expand the water flow area, while the smaller inner diameter of the constriction part 1103 slows down the water flow rate, allowing the water to remain fully still in the bucket, and allowing the fine impurities remaining in the water to settle and separate further. Together with the water inlet groove 1101 on the inner circumference of the lower bucket 1102, it achieves uniform water flow and stable output, avoiding unstable water level contact of the ultrasonic atomizing plate 15 due to water flow fluctuations, and ensuring the continuity of the atomization process and the uniformity of droplets.

[0035] Furthermore, a first worm gear 25 is fixedly connected to the outer circumference of the second rotating column 23, a first worm wheel 26 meshes with the outer circumference of the first worm gear 25, and a third rotating column 27 is fixedly connected to the inner circumference of the first worm wheel 26. One end of the third rotating column 27 is rotatably connected to the horizontal plate 14, and the other end of the third rotating column 27 extends into the interior of the protective shell 5. A second worm gear 30 is fixedly connected to the outer circumference of the third rotating column 27 located inside the protective shell 5, and a second worm gear 30 is fixedly connected to the outer circumference of the spray pipe 7. The second worm gear 31 meshes with the second worm 30. The other end of the spray pipe 7 is rotatably connected to the mist delivery cylinder 6. A guide groove 28 is provided at one end of the spray pipe 7 near the mist delivery cylinder 6, and a mist outlet groove 29 is provided at the other end of the spray pipe 7. The mist outlet groove 29 is connected to the guide groove 28. While the motor 24 drives the second rotating column 23 to rotate, the second rotating column 23 can drive the first worm 25 on its outer wall to rotate together. Through the meshing between the first worm 25 and the first worm gear 26, thus… The third rotating column 27 can be driven to rotate. When the third rotating column 27 rotates, the part of it extending into the protective shell 5 will drive the second worm gear 30 fixedly connected to the outer wall to rotate synchronously. The meshing transmission between the second worm gear 30 and the second worm wheel 31 fixed to the outer wall of the spray pipe 7 drives the spray pipes 7, which are distributed at equal distances, to rotate synchronously. During the rotation of the spray pipe 7, the guide groove 28 near the mist delivery cylinder 6 can smoothly guide the mist in the mist delivery cylinder 6 into the pipe, and then spray it out through the wave-shaped mist outlet groove 29 connected to the guide groove 28 at the other end. At this time, the mist is sprayed out in a spiral state. The spiral spray of the spray pipe 7 can not only enhance the mist pressure and make the path of the mist after it is sprayed out longer, but also achieve 360-degree uniform spray without dead angles. This allows the waterproof board to effectively contact the mist droplets at both ends near and far from the entire device, solving the problem of limited spray range and difficulty in covering the far end and inner side of the stacked board by the mist in traditional general-purpose humidifiers.

[0036] Furthermore, the cross-section of the mist outlet groove 29 is wavy. The inner diameter of the mist outlet groove 29 gradually decreases along the vertical downward direction of the mist delivery cylinder 6. After the mist is blown out, it will gradually sink, which may cause the amount of mist received by the waterproof board stacked on top to be less than that received by the waterproof board stacked below. At this time, the design of the mist outlet groove 29 with the inner diameter gradually decreasing along the vertical downward direction of the mist delivery cylinder 6 can specifically compensate for the impact of the mist sinking, and avoid the situation where the waterproof board below has excessive humidity while the board above has insufficient humidity.

[0037] In summary, with the help of the above-mentioned technical solution of the present invention, during use, the staff first pushes the entire equipment to the side of the rack where waterproof boards are stacked. Then, the staff injects an appropriate amount of water through the water inlet 3 at the top of the box 1. At this time, the injected clean water is guided to flow smoothly through the first baffle 8, which is inclined and has an arc-shaped groove 9. It then flows into the bottom of the box 1 through the through groove 13 of the second baffle 12. The water flowing into the bottom of the box 1 then flows into the settling hopper 11 through the water inlet 1101. When the water level in the settling hopper 11 rises to contact the ultrasonic atomizing plate 15, the ultrasonic atomizing plate 15 will convert the contacting clean water into fine and uniform mist droplets, providing suitable atomized water vapor for the maintenance of waterproof boards. This effectively avoids the board quality problems caused by uneven water supply in traditional maintenance. Moreover, after the clean water is injected, the arc-shaped groove 9 on the first baffle 8 can effectively form multi-stage sedimentation. The slow flow and backflow of water in the arc-shaped groove 9 are utilized. Impurities and particulate matter in the water gradually settle under gravity, reducing the amount of impurities adhering to the surface of the ultrasonic atomizing plate 15. This ensures the stability of the atomization effect, extends the service life of the atomizing plate, and prevents impurities from being sprayed out with the mist, thus affecting the quality of the board curing. At the same time, the special structure of the settling bucket 11 further optimizes the water quality and water supply stability. The upper bucket 1104, the constriction part 1103, and the lower bucket 1102 of the settling bucket 11 form a unique buffer space. The upper bucket 1104 and the lower bucket 1102, with their semi-circular cross-sections, expand the water flow area, while the constriction part 1103, with its smaller inner diameter, slows down the water flow rate, allowing the water to settle fully in the bucket. This allows the fine impurities remaining in the water to further settle and separate. Combined with the water inlet groove 1101 on the inner circumference of the lower bucket 1102, this achieves uniform water flow and stable output, preventing unstable water levels in contact with the ultrasonic atomizing plate 15 due to water flow fluctuations, and ensuring the continuity of the atomization process and the uniformity of the droplets. When the ultrasonic atomizing plate 15 atomizes the water, the mist enters the mist delivery cylinder 6. At this time, the blowing assembly inside the mist delivery cylinder 6 works synchronously. The motor 24 drives the second rotating column 23 to rotate, and through the meshing of the second helical gear 22 and the first helical gear 18, it drives the first rotating column 16 to rotate, causing the fan blades 19 on the bushing 20 to rotate at high speed. Since the front surface and side of the blade 1901 are respectively provided with the first protrusion 1902, the guide strip 1904, the second protrusion 1905, and the tooth block 1903, the three-stage coordinated turbulence mechanism can achieve efficient atomization and diffusion of the mist droplets generated by the ultrasonic atomizing plate 15. Specifically, this is achieved through the first protrusion 1902 on the surface of the blade 1901. 02 and the second protrusion 1905 first block and divert the incoming mist flow on a large scale, generating a radial velocity component, which initially expands the concentrated mist. Subsequently, the wave-shaped guide strip 1904 in the middle causes the airflow to generate periodic fluctuations and small-scale vortices, promoting the collision, mixing and breaking of mist droplets into finer particles. Finally, the isosceles triangular tooth block 1903 on the trailing edge of the blade 1901 forms a strong shearing effect and periodic vortex street at the outlet, which performs final shearing and tearing on the mist flow, so that the blown mist can achieve a large-scale, uniform and delicate dispersion effect while maintaining the wind speed, ensuring that the fine mist can better penetrate into the gaps between the stacked waterproof boards. While the motor 24 drives the second rotating column 23 to rotate, the second rotating column 23 can also drive the first worm 25 on its outer wall to rotate. Through the meshing between the first worm 25 and the first worm wheel 26, the third rotating column 27 can be driven to rotate. When the third rotating column 27 rotates, the part extending into the protective shell 5 will drive the second worm 30 fixedly connected to the outer wall to rotate synchronously. Utilizing the meshing transmission between the second worm 30 and the second worm wheel 31 fixed to the outer circumference of the spray pipe 7, the equally spaced spray pipes 7 are driven to rotate synchronously. During the rotation of the spray pipe 7, the guide groove 28 near the mist delivery cylinder 6 can smoothly guide the mist in the mist delivery cylinder 6 into the pipe, and then spray it out through the wavy mist outlet groove 29 connected to the guide groove 28 at the other end. The mist is sprayed out in a spiral pattern. The self-rotating spiral spray of the spray pipe 7 not only enhances the mist pressure and makes the mist drift a longer path after being sprayed out, but also achieves uniform spraying with no dead angles. This ensures that both ends of the waterproof board, near and far from the entire device, can effectively contact the mist droplets. This solves the problem of limited spray range and difficulty in covering the far and inner sides of stacked boards by the mist in traditional general-purpose humidifiers. After the mist is blown out, it will gradually sink, which may cause the waterproof board stacked on top to receive less mist than the waterproof board stacked on the bottom. At this time, the design of the mist outlet groove 29, which has a gradually decreasing inner diameter along the vertical downward direction of the mist delivery cylinder 6, can specifically compensate for the impact of the mist sinking, avoiding the situation where the waterproof board below has excessive humidity while the board above has insufficient humidity.
