Abstract
Description
Technical Field
[0001] This utility model relates to the field of household water purifier technology, specifically to a noise reduction housing for a water purifier. Background Technology
[0002] Household water purifiers are home water purification devices that use technologies such as filtration, adsorption, and reverse osmosis to remove impurities and pollutants from tap water and improve water quality. Their core function is to make drinking water cleaner and safer, and they are also suitable for scenarios such as direct drinking, cooking, and tea brewing in the family kitchen.
[0003] When a household water purifier is in use, the pump generates low-frequency noise, producing a continuous "humming" sound. The flow of water within the device also generates noise. Existing household water purifier enclosures merely serve to secure the booster pump, filter cartridges, and other components. While this physical isolation reduces some noise, the lack of a dedicated noise reduction structure means that the noise propagation path is not effectively blocked. Sound waves can easily diffuse through gaps in the enclosure and through material conduction. The noise reduction effect is far from meeting users' needs for a quiet environment. Therefore, this paper proposes a noise-reducing enclosure for water purifiers to address the aforementioned problems. Utility Model Content

[0012] Furthermore, the first noise reduction plate includes a first spiral plate, the top of the first spiral plate is provided with a first spiral surface, and a plurality of first noise reduction holes are provided along the edge of the first spiral surface. The plurality of first noise reduction holes are divided into two groups. One group of first noise reduction holes is distributed in a ring at equal intervals along the inner edge of the first spiral surface, and the other group of first noise reduction holes is distributed in a ring at equal intervals along the outer edge of the first spiral surface.
[0013] Furthermore, the lower surface of the first spiral plate is provided with a plurality of second hollow cylinders and a first noise-reducing fine hair, the first noise-reducing fine hair and the first noise-reducing hole are staggered, and the upper surface of the first spiral plate is provided with a plurality of second connecting holes, the plurality of second connecting holes correspond to the plurality of second hollow cylinders and are interconnected, the second connecting holes correspond to the first hollow cylinder.
[0014] Furthermore, the second noise reduction plate includes a second spiral plate, the top of which is provided with a second spiral surface, and a plurality of second noise reduction holes are provided along the center of the second spiral surface.

By alternating the arrangement of the first and second noise reduction plates, the sound waves are consumed as much as possible within the relatively narrow noise reduction mounting slot. Furthermore, the sound wave propagation is restricted by the noise reduction holes, ensuring that the sound waves are positioned directly below the noise reduction fibers when they propagate through the holes, thereby allowing the sound waves to directly act on the noise reduction fibers and increasing their working efficiency.

[0021] Please see Figure 1 , Figure 2 , Figure 4 as well as Figure 5 A noise reduction housing for a water purifier, characterized in that it comprises: a housing shell 1 and a noise reduction component; The outer shell 1 of the enclosure is provided with a box groove 13 and a noise reduction mounting groove 14, and the box groove 13 and the noise reduction mounting groove 14 are connected to each other. The outer shell 1 includes a main shell 11. The upper surface of the main shell 11 is provided with a groove 13 and a noise reduction mounting groove 14 from the inside to the outside. The noise reduction mounting groove 14 is a U-shaped groove. The groove 13 is located at the center of the noise reduction mounting groove 14. The bottom of the inner wall of the groove 13 is provided with a connecting hole 15, which can connect the groove 13 and the noise reduction mounting groove 14. The side of the main shell 11 is provided with a plurality of mounting ears 12, which are symmetrically distributed. Based on the above, the design of the housing groove 13 allows for the installation of components such as pumps and valve cores. At this time, the noise reduction mounting groove 14 surrounds the outside of the housing groove 13, which has the effect of isolating sound waves. Furthermore, through the design of the connecting hole 15, sound waves can be transmitted to the inside of the noise reduction mounting groove 14. The design of the noise reduction mounting groove 14 can consume sound waves to a certain extent, and the noise reduction component can be installed inside the noise reduction mounting groove 14. The design of the mounting ear 12 allows the noise reduction component to be connected and fixed to the housing shell 1.
[0022] like Figures 1-3 as well as Figure 6 As shown, the top cover 2 includes a cover plate 21 disposed at the top of the main housing 11. The side of the cover plate 21 is provided with a plurality of connecting ears 23. The connecting ears 23 are connected to the mounting ears 12 by screws and nuts. The upper surface of the cover plate 21 is provided with a window 22. The size of the window 22 is only enough to allow the water inlet pipe, the water outlet pipe and the cable to extend. The window 22 is connected to the tank 13. The lower surface of the cover plate 21 is provided with a plurality of first hollow cylinders 24, and the upper surface is provided with a plurality of first connecting holes 25. The plurality of first connecting holes 25 correspond to the plurality of first hollow cylinders 24 and are interconnected. The first hollow cylinders 24 extend into the interior of the noise reduction mounting groove 14. Based on the above, the top cover 2 is connected to the mounting ear 12 by means of the connecting ear 23. After connection, the top cover 2 is fixed to the top of the main housing 11. At this time, the first hollow cylinder 24 extends into the interior of the noise reduction mounting groove 14. The window 22 allows the water inlet pipe, water outlet pipe and cable connection required by the booster pump, filter element and other components set in the box groove 13 to extend normally.
[0023] like Figure 2 and Figure 3As shown, the noise reduction assembly includes a first noise reduction plate 3 and a second noise reduction plate 4, which are alternately arranged from top to bottom. Both of them have noise reduction hairs on their lower surfaces. One end of each noise reduction hair is fixed and the other end can swing. The noise reduction assembly also includes a top cover 2. The bottom of the top cover 2 is alternately arranged with the first noise reduction plate 3 and the second noise reduction plate 4 from top to bottom. The top cover 2, the first noise reduction plate 3, and the second noise reduction plate 4 are connected to each other by screws and nuts. The first noise reduction plate 3 and the second noise reduction plate 4 are both disposed inside the noise reduction mounting groove 14. Based on the above, the bottom of the top cover 2 is provided with a first noise reduction plate 3 and a second noise reduction plate 4. The first noise reduction plate 3 and the second noise reduction plate 4 are alternately arranged so that when the sound wave propagates from bottom to top, it can be weakened and consumed by the two noise reduction plates in sequence. The number of the two noise reduction plates can be adjusted according to the actual situation.
[0024] like Figure 7 As shown, the first noise reduction plate 3 includes a first spiral plate 31. The top of the first spiral plate 31 is provided with a first spiral surface 32. A plurality of first noise reduction holes 33 are provided along the edge of the first spiral surface 32. The plurality of first noise reduction holes 33 are divided into two groups. One group of first noise reduction holes 33 is distributed in a ring at equal intervals along the inner edge of the first spiral surface 32, and the other group of first noise reduction holes 33 is distributed in a ring at equal intervals along the outer edge of the first spiral surface 32. The lower surface of the first spiral plate 31 is provided with a plurality of second hollow cylinders 34 and a first noise-reducing fine hair 36. The first noise-reducing fine hair 36 is staggered with the first noise-reducing hole 33. The upper surface of the first spiral plate 31 is provided with a plurality of second connecting holes 35. The plurality of second connecting holes 35 correspond to the plurality of second hollow cylinders 34 and are interconnected. The second connecting holes 35 correspond to the first hollow cylinder 24. Based on the above, the first spiral plate 31 is designed to be compatible with the noise reduction mounting groove 14, ensuring that it extends into the interior of the noise reduction mounting groove 14. The first noise reduction hole 33 allows sound waves to propagate upwards in a directional manner, meaning that sound waves can more easily propagate upwards through the first noise reduction hole 33. The first noise reduction bristles 36 are designed so that when sound waves propagate, air vibration drives the bristles to move, and the sound waves are consumed by the bristles doing work, thereby achieving the effect of active noise reduction.
[0025] like Figure 8As shown, the second noise reduction plate 4 includes a second spiral plate 41. The top of the second spiral plate 41 is provided with a second spiral surface 42. A plurality of second noise reduction holes 43 are provided along the center of the second spiral surface 42. The plurality of second noise reduction holes 43 are equidistantly distributed and staggered from the first noise reduction holes 33. The lower surface of the second spiral plate 41 is provided with a plurality of third hollow cylinders 44 and second noise reduction hairs 46. The second noise reduction hairs 46 are staggered from the second noise reduction holes 43. The upper surface of the second spiral plate 41 is provided with a plurality of third connecting holes 45. The plurality of third connecting holes 45 correspond to the plurality of third hollow cylinders 44 and are interconnected. The third connecting holes 45 correspond to the second connecting holes 35. The second noise reduction hole 43 is located directly below the first noise reduction bristle 36, and the second noise reduction bristle 46 is located directly above the first noise reduction hole 33. The screw passes through the first hollow cylinder 24, the second connecting hole 35, the second hollow cylinder 34, the third connecting hole 45, and the third hollow cylinder 44 in sequence before being connected to the nut. Based on the above, the second noise reduction plate 4 achieves the same effect as the first noise reduction plate 3. The second noise reduction bristles 46 correspond to the first noise reduction hole 33, allowing the sound waves propagating upward through the first noise reduction hole 33 to directly contact the second noise reduction bristles 46, thereby increasing the efficiency of the bristles in consuming sound wave energy. The first noise reduction bristles 36 and the second noise reduction hole 43 work together to achieve the same effect as the aforementioned noise reduction bristles and noise reduction hole.
[0026] In summary, this noise reduction enclosure, through the combination of the U-shaped noise reduction mounting slot 14 and the alternately arranged noise reduction plates, combined with the kinetic energy dissipation effect of the noise reduction hairs, can effectively reduce low-frequency mechanical noise and fluid noise, with a noise reduction of 15-25dB, meeting the needs of noise-sensitive families.
[0027] The working principle is as follows; When the water purifier is working, the noise generated by the booster pump and water flow forms sound waves. The sound waves enter the interior of the U-shaped noise reduction mounting groove 14 through the connecting hole 15 at the bottom of the inner wall of the tank 13.
[0028] The sound wave propagates upward in the noise reduction mounting groove 14 and first contacts the second noise reduction plate 4. Part of the sound wave propagates upward through the second noise reduction hole 43 and directly acts on the first noise reduction hair 36 of the first noise reduction plate 3 above, causing the hair to sway. During the movement of the hair, the vibration kinetic energy of the sound wave is consumed. The remaining sound wave is reflected by the surface of the second noise reduction plate 4 and interferes with and cancels out the sound wave that propagates afterward.
[0029] The sound waves passing through the first noise-reducing bristles 36 continue to propagate upwards, and after passing through the first noise-reducing hole 33, they act on the second noise-reducing bristles 46 below the top cover 2, where the kinetic energy is dissipated again by the movement of the bristles. At the same time, the sound-absorbing cotton layer on the inner wall of the noise-reducing mounting groove 14 absorbs some of the sound wave energy, further reducing the noise.
[0030] By alternating the first noise reduction plate 3 and the second noise reduction plate 4, and by staggering the noise reduction holes and noise reduction hairs, the sound waves are refracted, interfered with and consumed multiple times in a narrow space, ultimately achieving a highly efficient noise reduction effect.
[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
