Description

Technical Field

[0001] This invention relates to the field of water purification devices, specifically to a noise reduction device for pulsed water flow and a water outlet device using the same device. Background Technology

[0002] Filtration products with booster pumps generate high-frequency pulsed water pressure during water production, which acts on the water path and filter membrane. Simultaneously, the backflow of water pressure on the RO pump produces noticeable noise or abnormal sounds. Existing structures, such as the noise-reducing RO pump described in Chinese Utility Model Patent CN217898139U, can reduce noise by adding some soft-fixed vibration damping measures. However, this structure does not specifically address the pulsed water flow that generates the most noise. Therefore, the noise reduction is uniform across the entire system, and the noise reduction effect is not significant. Summary of the Invention

[0003] This invention addresses the issue of high noise generated by pulsed water flow in RO pumps by proposing a noise reduction device for pulsed water flow. The device performs multi-stage noise reduction on the pulsed water flow in the RO pump, thereby reducing the noise generated during the operation of the RO pump.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a noise reduction device for pulsed water flow, comprising an outlet channel and an inlet channel, wherein a buffer chamber is provided between the inlet channel and the outlet channel, the buffer chamber being a cylindrical structure, and a buffer member is provided inside the cylindrical structure to smooth the pulsed water flow entering from the inlet channel; the surface of the buffer member near the pulsed water flow is a bowl-shaped structure, the convex surface of the bowl-shaped structure facing the pulsed water flow; the buffer member includes at least one elastic structure.

[0005] Preferably, the cushioning component includes a first soft rubber structure and a second soft rubber structure. The first soft rubber structure is a bowl-shaped structure, and the second soft rubber structure is located above the first soft rubber structure. The second soft rubber structure is a cylindrical structure, and the outer surface of the cylindrical structure is a layered structure for cushioning.

[0006] Preferably, the cushioning element includes a bowl-shaped soft rubber structure and a spring, the spring being disposed above the bowl-shaped soft rubber structure and surrounding the inner wall of the cushioning chamber.

[0007] Preferably, the cushioning component includes bubble wrap, the bottom of which has a bowl-shaped structure, and the bubble wrap fills the entire interior of the cushioning chamber.

[0008] Preferably, the water inlet channel is located on the side of the bottom of the buffer chamber, and the water outlet channel is located on the lower surface of the bottom of the buffer chamber.

[0009] Preferably, the connection between the water outlet channel and the buffer chamber has a cylindrical structure, which extends from the bottom of the buffer chamber into the interior of the buffer chamber.

[0010] Preferably, the distance from the upper surface of the cylindrical structure to the lower surface of the buffer chamber is less than the distance from the lowest point of the bowl-shaped structure to the lower surface of the buffer chamber.

[0011] An RO pump, the outlet water path of which includes a noise reduction device for pulsed water flow as described above.

[0012] A water purification device, characterized in that it includes the RO pump described above.

[0013] The present invention has the following beneficial effects: By adding a noise reduction device to the water circuit, the amplitude of the high-pulse water flow impacting the dense reverse osmosis membrane is effectively reduced. At the same time, the backflow water pulse is also buffered by the pulse suppression device and will not directly impact the high-speed booster pump, thereby effectively reducing the noise generated by the RO pump during operation.

[0028] Example

[0029] The following are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the following embodiments. All technical solutions that fall within the scope of the present invention are within the scope of protection of the present invention.

[0030] Reference manual attached Figure 1 A noise reduction device for pulsed water flow includes an outlet channel 3 and an inlet channel 2. A buffer chamber 1 is provided between the inlet channel 2 and the outlet channel 3. The inlet channel and the outlet channel can interchange their inlet and outlet directions (i.e., the inlet channel is used for outlet water while the outlet channel is used for immersion water). The buffer chamber 1 is a cylindrical structure. A buffer element is provided inside the cylindrical structure to smooth the pulsed water flow entering from the inlet channel. The surface of the buffer element near the pulsed water flow is a bowl-shaped structure, with the convex surface of the bowl-shaped structure facing the pulsed water flow. A buffer chamber cover 4 is provided above the buffer chamber 1. The buffer chamber cover 4 is detachably connected to the buffer chamber 1 for replacing the buffer element as needed. The buffer chamber cover 4 has a cover protrusion 41 facing the inside of the buffer chamber 1 to fix the buffer element. The cover protrusion 41 is also a cylindrical structure.

[0031] The water inlet channel is located on the side of the bottom of the buffer chamber, and the water outlet channel is located on the lower surface of the bottom of the buffer chamber. A cylindrical structure 31 connects the water outlet channel 3 to the buffer chamber 1, extending from the bottom of the buffer chamber into its interior. The distance from the upper surface of the cylindrical structure to the lower surface of the buffer chamber is less than the distance from the lowest point of the bowl-shaped structure to the lower surface of the buffer chamber. This design ensures that the water flow is gentle before exiting the chamber. (See the attached instruction manual.) Figure 2-4 The water flow direction arrows indicate that the pulsed water first flows to the buffer device for buffering. A portion of the pulsed water is smoothed out by the bottom of the bowl-shaped structure and flows to the bottom of the buffer chamber. After touching the outer surface of the cylindrical structure 31, it is smoothed out again and flows to the bottom of the outlet channel 3. After being smoothed out at the bottom of the outlet channel 3, it flows out from the outlet channel 3. This not only allows the pulsed water to undergo multi-stage smoothing and noise reduction, but also effectively reduces the amplitude of the high-pulse water flow impacting the dense reverse osmosis membrane. At the same time, the backflow pulsed water is also buffered by the pulse suppression device and will not directly impact the high-speed booster pump, thus effectively reducing the noise generated by the RO pump during operation.

[0032] Reference manual attached Figure 2 This is a first embodiment of the present invention. In this embodiment, the buffer includes a first soft rubber structure 101 and a second soft rubber structure 102. The first soft rubber structure 101 is a bowl-shaped structure, and the second soft rubber structure 102 is located above the first soft rubber structure 101. The second soft rubber structure 102 is a cylindrical structure, and the outer surface of the cylindrical structure is a layered structure for buffering.

[0033] Reference manual attached Figure 3 In a second embodiment of the present invention, the buffer component includes a bowl-shaped soft rubber structure 111 and a spring 112. The spring 112 is disposed above the bowl-shaped soft rubber structure 111 and surrounds the inner wall of the buffer chamber. A sealing ring 113 for waterproofing is provided between the bowl-shaped soft rubber structure 111 and the spring 112. By using buffer components made of different materials and by adding springs to increase the elasticity of the buffer components, the buffering effect of pulsating water is increased.

[0034] Reference manual attached Figure 4 This is the third embodiment of the present invention. In this embodiment, the buffer includes bubble wrap 121. The bottom of the bubble wrap 121 has a bowl-shaped structure, and the bubble wrap 121 fills the entire interior of the buffer chamber.

[0035] Reference manual attached Figure 5 This is the third embodiment of the present invention. In this embodiment, the buffer element is a buffer soft rubber 131, which fills the entire interior of the buffer chamber and has a planar structure.

[0036] For the first to fourth embodiments, the buffer can be replaced as needed. If buffering of large-flow pulsed water is required, the buffer of the second embodiment can be considered. If the service life of the buffer is considered, the buffer of the second embodiment can be considered. The buffer material, in addition to the attached... Figure 2-5 The material may also be composed of silicone, silicone rubber, rubber, spring, PVC, EVA, POE, TPES, foam, or be filled with elastic material in the buffer chamber, including but not limited to the above materials.

[0037] Reference manual attached Figure 6-7 The noise reduction device for the pulsed water flow is installed in the outlet water path of the RO pump. After the water is filtered by the RO pump, it is discharged through the outlet water path of the RO pump and then enters the inlet water path of the drinking water purification device.
