Description

Technical Field

[0001] This invention relates to the field of water purification equipment technology, and specifically to a low-noise water purifier. Background Technology

[0002] Existing water purifiers typically use booster pumps to pressurize the water and increase the flow rate. However, the pulsating water flow generated during the pumping process impacts the outlet pipe, causing significant vibration and noise, thus reducing the user experience. To address this issue, existing water purifiers usually incorporate a damping noise reduction device in the middle of the booster pump's outlet pipe. This device reduces the energy of the pulsating water flow, thereby minimizing noise.

[0003] However, placing the damping silencer on the main flow path of the outlet pipe results in pressure loss as water flows through it, increasing resistance in the outlet pipe. This leads to increased vibration and noise from the booster pump itself, affecting the actual noise reduction effect of the damping silencer. Furthermore, the booster pump outlet pipe carries unfiltered raw water containing high levels of calcium and magnesium ions. The flow rate slows as the raw water passes through the damping element, and the damping device has many dead zones where dirt and grime can easily accumulate. Over time, this can cause scale buildup in the damping silencer, potentially leading to blockages and preventing the water purifier from producing water, thus impacting the user experience. Summary of the Invention

[0004] The purpose of this invention is to provide a low-noise water purifier to solve the problems that existing noise reduction components can easily cause increased water flow resistance in the outlet pipe of the booster pump, increase vibration and noise, and cause blockage, thus affecting the water output of the water purifier.

[0005] To achieve the above objectives, the present invention provides a low-noise water purifier, comprising a booster pump having an inlet and an outlet, an inlet pipe and an outlet pipe, the inlet pipe being connected to the inlet, the outlet pipe being connected to the outlet, the outlet pipe comprising a main channel and a noise-reducing bypass tributary channel connected to the main channel, the noise-reducing bypass tributary channel comprising at least two water inlets, the water inlets guiding some water in the main channel into and out of the noise-reducing bypass tributary channel to buffer the water flow in the main channel.

[0006] This invention provides a main channel and a noise-reducing bypass tributary connected to the main channel within the water outlet pipe. The noise-reducing bypass tributary includes at least two inlets that guide some water from the main channel into and out of the noise-reducing bypass tributary, thus buffering the water flow in the main channel. This allows the high-pressure pulsating water flow in the main channel to be diverted to the noise-reducing bypass tributary for buffering, forming a stable water flow before flowing back into the main channel and merging with it. This not only does not increase the water flow resistance in the main channel, ensuring the normal water outlet speed, but also buffers and slows down the high-pressure pulsating water flow in the main channel, thereby stabilizing the water flow and reducing noise within the water outlet pipe, thus improving the noise reduction effect of the water purifier.

[0007] Preferably, there are two water inlets, one for the main channel and one for the outlet, so that some water in the main channel flows into the noise reduction bypass tributary through the inlet and then flows back to the main channel through the outlet.

[0008] By setting the inlet and outlet as the water outlet, the high-pressure pulsating water flow in the main channel flows into the noise reduction bypass tributary through the inlet. After being buffered and slowed down by the noise reduction bypass tributary, it flows into the main channel through the outlet and merges with the water flow there. This not only does not increase the water flow resistance in the main channel and ensures the normal water output speed in the main channel, but also extends the buffer path of the pulsating water flow, further buffering and slowing down the pulsating water flow in the main channel to form a stable water flow. This reduces the vibration noise generated by the impact of the high-pressure pulsating water flow on the pipe wall of the outlet pipe, thus achieving the purpose of noise reduction.

[0009] Preferably, a buffer is provided between the end of the noise reduction bypass tributary adjacent to the inlet and the inlet. The buffer is located between the end of the noise reduction bypass tributary and the inlet, and the water-facing surface of the buffer is perpendicular to the water flow direction in the noise reduction bypass tributary.

[0010] By installing a buffer between the inlet and the end of the noise reduction bypass tributary near the inlet, the high-pressure pulsating water flow entering the noise reduction bypass tributary can be quickly buffered and decelerated, thereby stabilizing the water flow and reducing noise. At the same time, by setting the water-facing surface of the buffer to be perpendicular to the water flow direction in the noise reduction bypass tributary, the contact area between the buffer and the water is increased, further enhancing the buffering and deceleration effect on the high-pressure pulsating water flow entering the noise reduction bypass tributary, improving the water flow stabilization effect, and enhancing the noise reduction effect.

[0011] Preferably, the water-facing surface of the buffer element is recessed towards the end of the noise reduction bypass tributary near the inlet.

[0012] By recessing the water-facing surface of the buffer component towards the end of the noise-reducing bypass tributary near the inlet, an arc-shaped concave structure is formed on the water-facing surface of the buffer component. This guides the high-pressure pulsating water flow that has just entered the noise-reducing bypass tributary, allowing the high-pressure pulsating water flow to act more evenly on the water-facing surface of the buffer component. This reduces the possibility of uneven action of the high-pressure pulsating water flow on the surface of the buffer component, which could lead to deformation or even damage to the buffer component and thus prevent it from effectively buffering the high-pressure pulsating water flow. This extends the service life of the buffer component and improves the noise reduction effect of the water purifier.

[0013] Preferably, the buffer is provided with multiple sound-absorbing holes, and the back surface of the buffer is provided with partition ribs corresponding to the sound-absorbing holes, so that multiple sound-absorbing cavities are formed on the back side of the buffer.

[0014] By incorporating multiple silencing holes on the buffer component, the high-pressure pulsating water flow into the noise-reducing bypass tributary is divided into two parts: one part flows towards the outlet, and the other flows in the opposite direction. The water flowing in the opposite direction enters the noise-reducing bypass tributary through these silencing holes under the action of the buffer component. These silencing holes effectively slow down the water flow and make the flow into the noise-reducing bypass tributary more uniform, further enhancing the noise reduction effect. Simultaneously, the partition ribs divide the internal space of the buffer component into multiple individual spaces. These spaces, together with the buffer component, form multiple Helmholtz resonant cavities to reduce the vibrations generated by the high-pressure pulsating water flow, stabilize the water flow, and reduce noise, further enhancing the noise reduction effect of the buffer component and the noise-reducing bypass tributary.

[0015] Preferably, the outlet pipe includes a detachably connected first housing and a second housing, which together form a noise-reducing bypass branch channel.

[0016] By making the first and second housings detachably connected, the noise-reducing bypass branch channel can be easily disassembled, thus facilitating the cleaning of scale inside the channel and simplifying the cleaning process. Simultaneously, when the noise-reducing bypass branch channel malfunctions, it can be easily disassembled for repair, simplifying the repair process and facilitating the replacement of its components. This simplifies operation, reduces the cost of maintaining the water purifier, and enhances the user experience.

[0017] Preferably, the outlet pipe includes a detachably connected first housing and a second housing, which together form a water flow channel. The water flow channel is provided with a guide pipe having multiple water inlets to divide the water flow channel into a main flow channel and a noise-reducing bypass branch channel located within the guide pipe. This allows the high-pressure pulsating water flow in the main flow channel to flow relatively quickly into the noise-reducing bypass branch channel, and the high-pressure pulsating water flow is quickly buffered and decelerated to form a stable water flow, improving the noise reduction effect. Simultaneously, the main flow channel and the noise-reducing bypass branch channel are integrated into one unit, facilitating installation in the water purification system and improving installation efficiency.

[0018] Preferably, the inner cavity of the guide tube is provided with a silencing rod extending along the axial direction of the guide tube and a silencing surface arranged around the silencing rod, with multiple silencing surfaces arranged at intervals along the silencing rod.

[0019] By setting a silencing rod extending along the axial direction of the guide tube and a silencing surface surrounding the silencing rod, the interior of the guide tube can form multiple Helmholtz resonant cavities through the silencing rod and the silencing surface, thereby reducing the vibration generated by high-pressure pulsating water flow, stabilizing the water flow, and reducing noise.

[0020] Preferably, the silencing rod is provided with silencing holes.

[0021] By incorporating silencing holes on the silencer bar, the pressure inside the bar is reduced, preventing damage caused by large amounts of high-pressure pulsating water entering and thus hindering effective silencing. Furthermore, when the high-pressure pulsating water flows across the surface of the silencer bar, some of it enters the interior through the guide holes, ensuring a more even flow and uniform water flow. This results in a more uniform water flow impact on the silencer bar, preventing damage caused by uneven water flow over time and extending its service life. Ultimately, this makes the silencing effect more reliable.

[0022] Preferably, the water purifier also includes an outer casing, with the booster pump and outlet pipe arranged horizontally within the outer casing, and the noise reduction bypass tributary located below the main channel.

[0023] By housing the booster pump and outlet pipe within the outer casing, the main components of the water purifier are protected from corrosion caused by air, preventing damage and malfunction. This also avoids damage to the components from external forces, extending the purifier's lifespan and ensuring more stable and reliable operation. Furthermore, placing the noise-reducing bypass tributary below the main flow channel allows some of the high-pressure pulsating water entering the main flow channel to flow into the noise-reducing bypass tributary due to gravity, thus achieving noise reduction. This prevents blockage of the main flow channel, maintains the water flow rate, and avoids affecting the water production capacity, enhancing the user experience. Attached Figure Description

[0046] To more clearly illustrate the overall concept of the present invention, a detailed description will be provided below with reference to the accompanying drawings and examples.

[0047] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0048] like Figures 1 to 15As shown, in one embodiment of the present invention, a low-noise water purifier is provided, including a booster pump 1 with an inlet and an outlet, an inlet pipe 2 and an outlet pipe. The inlet pipe 2 is connected to the inlet, and the outlet pipe is connected to the outlet. The outlet pipe includes a main channel 3 and a noise-reducing bypass branch channel 41 connected to the main channel 3. The noise-reducing bypass branch channel 41 includes at least two water inlets 411. The water inlets 411 guide water in the main channel 3 to enter and exit the noise-reducing bypass branch channel 41 to buffer the water flow in the main channel 2.

[0049] This invention provides a main channel 3 and a noise-reducing bypass tributary 41 connected to the main channel 3 within the water outlet pipe. The noise-reducing bypass tributary 41 includes at least two inlets 411. The inlets 411 guide water from the main channel 3 into and out of the noise-reducing bypass tributary 41, thus buffering the water flow in the main channel 3. This allows the high-pressure pulsating water flow in the main channel 3 to be diverted to the noise-reducing bypass tributary 41 for buffering, forming a stable water flow before flowing back into the main channel 3 and merging with it. This not only does not increase the water flow resistance in the main channel 3, ensuring the normal water outlet speed of the main channel 3, but also buffers and slows down the high-pressure pulsating water flow in the main channel 3, thereby stabilizing the water flow and reducing noise in the water outlet pipe, thus improving the noise reduction effect of the water purifier.

[0050] It should be noted that this application does not specifically limit the structure of the noise reduction bypass tributary 41, which can be one of the following embodiments:

[0051] Example 1: As Figure 4 As shown, there are two water inlets 411, namely inlet 4111 and outlet 4112, so that some water in the outlet pipe 3 flows into the noise reduction bypass branch channel 41 through inlet 4111 and then flows back to the main channel 3 through outlet 4112.

[0052] By setting the water inlet 411 as an inlet 4111 and an outlet 4112, the direction of water flow is as follows: Figure 5 As shown by the arrow, the high-pressure pulsating water flow in the main channel 3 flows into the noise reduction bypass branch channel 41 through the inlet 4111. After being buffered and slowed down by the noise reduction bypass branch channel 41, it flows into the main channel 3 through the outlet 4112 and merges with the water flow inside. This not only does not increase the water flow resistance in the main channel 3 and ensures the normal water output and flow rate in the main channel 3, but also extends the buffer path of the pulsating water flow, further buffering and slowing down the pulsating water flow in the main channel 3 to form a stable water flow. This reduces the vibration noise generated by the impact of the high-pressure pulsating water flow on the pipe wall of the main channel 3, thus achieving the purpose of noise reduction.

[0053] Furthermore, such as Figure 4As shown, a buffer 42 is provided between the end of the noise reduction bypass branch channel 41 adjacent to the inlet 4111 and the inlet 4111. The buffer 42 is located between the end of the noise reduction bypass branch channel 41 and the inlet 4111, and the water-facing surface of the buffer 42 is perpendicular to the water flow direction in the noise reduction bypass branch channel 41.

[0054] By providing a buffer 42 between the end of the noise reduction bypass branch channel 41 adjacent to the inlet 4111 and the inlet 4111, the high-pressure pulsating water flow entering the noise reduction bypass branch channel 41 can be quickly buffered and decelerated, thereby stabilizing the water flow and reducing noise. At the same time, by setting the water-facing surface of the buffer 42 to be perpendicular to the water flow direction in the noise reduction bypass branch channel 41, the contact area between the buffer 42 and the water is increased, further enhancing the buffering and deceleration effect on the high-pressure pulsating water flow entering the noise reduction bypass branch channel 41, improving the role of stabilizing the water flow, and improving the noise reduction effect.

[0055] It should be noted that this application does not specifically limit the material of the buffer 42. As a preferred embodiment of this application, the buffer 42 may be an elastic and deformable flexible component.

[0056] By setting the buffer 42 as an elastic and deformable flexible component, when water flows through the buffer 42, the buffer 42 is elastic and deformable, which can effectively buffer the impact force brought by the water flow, avoid damage to the buffer 42 due to excessive impact force of the water flow, and improve the service life of the buffer 42.

[0057] Furthermore, such as Figure 4 As shown, the water-facing surface of the buffer 42 is recessed towards the end of the noise reduction bypass tributary 41 adjacent to the inlet 4111.

[0058] By recessing the water-facing surface of the buffer element 42 towards the end of the noise-reducing bypass branch channel 41 near the inlet 4111, the water-facing surface of the buffer element 42 forms an arc-shaped concave structure. This guides the high-pressure pulsating water flow that has just entered the noise-reducing bypass branch channel 41, allowing the high-pressure pulsating water flow to act more evenly on the water-facing surface of the buffer element 42. This reduces the possibility of uneven action of the high-pressure pulsating water flow on the surface of the buffer element 42, which could lead to deformation or even damage to the buffer element 42 and prevent it from effectively buffering the high-pressure pulsating water flow. This extends the service life of the buffer element 42 and improves the noise reduction effect of the water purifier.

[0059] Furthermore, such as Figure 6 As shown, the buffer 42 is provided with a plurality of noise reduction holes 421, and the back surface of the buffer 42 is provided with a partition rib 422 corresponding to the noise reduction holes 421, so that a plurality of noise reduction cavities are formed on the back side of the buffer 42.

[0060] By providing multiple silencing holes 421 on the buffer 42, the high-pressure pulsating water flow flowing into the noise reduction bypass branch channel 41 is divided into two parts. One part flows towards the outlet 4112, and the other part flows in the opposite direction to the outlet 4112. The water flowing in the opposite direction to the outlet 4112 enters the noise reduction bypass branch channel 41 through the multiple silencing holes 421 under the action of the buffer 42. Due to the silencing holes 421, the water flow can be effectively slowed down, and the water flow into the noise reduction bypass branch channel 41 can be made more uniform, further improving the noise reduction effect of the noise reduction bypass branch channel 41. At the same time, under the action of the partition ribs 422, the internal space of the buffer 42 is divided into multiple individual spaces. These multiple spaces, together with the buffer 42, form multiple Helmholtz resonant cavities to reduce the vibration generated by the high-pressure pulsating water flow, stabilize the water flow and reduce noise, further improving the noise reduction effect of the buffer 42 and the noise reduction bypass branch channel 41.

[0061] As a preferred embodiment of this method, such as Figure 4 As shown, the water outlet pipe includes a first housing 43 and a second housing 44 that are detachably connected, and the first housing 43 and the second housing 44 enclose each other to form a noise reduction bypass branch channel 41.

[0062] By making the first housing 43 and the second housing 44 detachably connected, the noise reduction bypass branch channel 41 can be easily disassembled, thereby facilitating the removal of scale inside the noise reduction bypass branch channel 41 and simplifying the steps involved in its disassembly. Simultaneously, when the noise reduction bypass branch channel 41 malfunctions, it is convenient to disassemble it for repair, simplifying the repair process and facilitating the replacement of its components. This simplifies operation; when the noise reduction bypass branch channel 41 malfunctions, only the first housing 43 and the second housing 44 need to be disassembled to repair or replace the faulty components, eliminating the need to replace the entire noise reduction bypass branch channel 41. This reduces the cost of maintaining the water purifier and improves the user experience.

[0063] Specifically, the specific implementation method of this embodiment is as follows: the outlet end of the water pipe is provided with a connector 33, the connector has a first connection port 331 and a second connection port 332 facing the same direction, the first connection port 331 and the second connection port 332 form the main channel 3, the connector 33 also includes a third connection port 333 and a fourth connection port 334, the third connection port 333 is connected to the inlet 4111 of the water outlet 411, and the fourth connection port 334 is connected to the outlet 4112, the noise reduction bypass branch channel 41 is arranged in parallel with the main channel 3, and the buffer 42 is located at one axial end of the noise reduction bypass branch channel 41.

[0064] Example 2: Figure 15 As shown, combined with Figure 13 The water outlet pipe includes a detachably connected first housing 31 and second housing 32. The first housing 31 and the second housing 32 enclose a water flow channel. A guide pipe 45 with multiple water inlets is provided in the water flow channel to divide the water flow channel 45 into a main flow channel 3 and a noise reduction bypass branch channel 41 located in the guide pipe 45. This allows the high-pressure pulsating water flow in the main flow channel 3 to flow into the noise reduction bypass branch channel 41 relatively quickly, and the high-pressure pulsating water flow is quickly buffered and decelerated to form a stable water flow, thereby improving the noise reduction effect. At the same time, the main flow channel 3 and the noise reduction bypass branch channel 41 are integrated into one unit, which is convenient for installation in the water purification system and improves the installation efficiency.

[0065] Preferably, multiple water inlets 411 are arranged at intervals along the axial direction of the guide pipe 45 to increase the contact area between the guide pipe 45 and the high-pressure pulsed water flow entering the noise reduction bypass branch channel 41, thereby increasing the effect of the buffer 42 in reducing the water flow velocity and thus improving the noise reduction effect of the noise reduction bypass branch channel 41.

[0066] Furthermore, such as Figure 15 As shown, the inner cavity of the guide tube 45 is provided with a silencing rod 46 extending along the axial direction of the guide tube 45 and a silencing surface 47 surrounding the silencing rod 46. Multiple silencing surfaces 47 are arranged at intervals along the silencing rod 46.

[0067] By providing a silencing rod 46 extending axially along the guide tube 45 and a silencing surface 47 surrounding the silencing rod 46, the interior of the guide tube can form multiple Helmholtz resonant cavities through the silencing rod 46 and the silencing surface 47, thereby reducing the vibration generated by the high-pressure pulsating water flow, stabilizing the water flow, and reducing noise.

[0068] Furthermore, such as Figure 12 As shown, a silencing hole 421 is provided on the silencing rod body 46.

[0069] By providing silencing holes 421 on the silencing rod 46, the pressure inside the silencing rod 46 can be reduced, preventing damage caused by a large amount of high-pressure pulsating water entering the silencing rod 46 and thus rendering it ineffective in silencing. On the other hand, when the high-pressure pulsating water from the main channel 3 flows over the surface of the silencing rod 46, some of the water enters the interior of the silencing rod 46 through the guide holes, allowing the water to enter the silencing rod 46 evenly and forming a uniform water flow. This makes the water impact on the silencing rod 46 more uniform, preventing damage caused by uneven water impact over a long period of time and thus extending the service life of the silencing rod 46, thereby making the silencing effect of the silencing rod 46 more reliable.

[0070] As a preferred embodiment of this application, such as Figure 1As shown, the water purifier also includes an outer casing 5, a booster pump 1 and a bracket disposed inside the outer casing 5. The booster pump 1 is fixedly installed on the bracket or casing by means of side hanging or suspension through the mounting assembly. The booster pump 1 and the water outlet pipe are both arranged horizontally inside the outer casing 5. The noise reduction bypass branch channel 41 is located below the main channel 3.

[0071] By placing the booster pump 1 and the outlet pipe inside the outer casing 5, the main components of the water purifier can be protected from corrosion by air, which could damage the components and prevent them from purifying water. This also prevents damage to the main components due to external forces, extending the lifespan of the water purifier and making its operation more stable and reliable. Furthermore, the noise-reducing bypass branch channel 41 is located below the main channel 3, allowing some of the high-pressure pulsating water entering the main channel 3 to flow into the noise-reducing bypass branch channel 41 under its own weight, thus achieving a noise reduction effect. This also prevents blockage of the main channel 3, does not affect the water flow rate of the water purifier, and avoids impacting the water production capacity, thereby improving the user experience.

[0072] Of course, the booster pump 1 can also be arranged vertically, that is, the outlet pipe 3 is vertical, and the noise reduction bypass branch channel 41 is located on the side of the main channel 3. There are no restrictions here.

[0073] The technical solutions protected by this invention are not limited to the above embodiments. It should be noted that any combination of the technical solutions of any embodiment with one or more other embodiments is within the protection scope of this invention. Although the invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this invention are within the scope of protection claimed by this invention.
