Description

Technical Field

[0001] The present invention relates to the technical field of water purification, and in particular to a water purification system and a water purifier. Background Art

[0002] In recent years, as consumers pay more and more attention to health products, water purification products have gradually become the focus of the market, which in turn has promoted the rapid development of the water purification industry. Among them, the reverse osmosis water purifier achieves reverse osmosis of tap water by applying a higher water pressure in front of the reverse osmosis membrane to produce pure water. In order to achieve the required water production efficiency, a high-power booster pump must be installed in front of the reverse osmosis membrane. During the entire operation of the water purifier, the booster pump will generate a certain amount of vibration at a high speed, which will be transmitted to the water purifier body, causing mechanical resonance and generating significant noise. This noise usually increases with the increase of the water purifier flux, seriously affecting the user experience and becoming a pain point in the use of current reverse osmosis water purifiers.

[0003] In this regard, in order to achieve noise reduction of reverse osmosis water purifiers, the industry generally installs soft rubber pads between the booster pump and the water purifier body, or installs an additional pump casing outside the booster pump, and uses the soft rubber pads and pump casing to reduce the vibration transmission between the booster pump and the water purifier body, thereby achieving the purpose of noise reduction. However, the material properties of the soft rubber pads and pump casings (such as hardness and damping ratio) determine the upper limit of their vibration isolation effect, making it difficult for the rubber pads and pump casings to effectively absorb and disperse vibration energy in high-frequency or high-intensity vibration environments. In addition, the vibration isolation performance of the soft rubber pads and pump casings will change with changes in vibration frequency and amplitude, and it is difficult to maintain stable vibration isolation performance within a wide frequency band. The above reasons all lead to limited noise reduction effects through soft rubber pads and pump casings, making it difficult to meet consumers' demand for quiet operation of water purifiers.

[0034] Embodiment 1:

[0035] refer to Figure 1 to Figure 5 A water purification system, which is the same as the existing water purification system for preparing purified water by reverse osmosis technology, includes a shell 1, on which a purified water waterway 2 is installed, and the purified water waterway 2 is connected in series in a preset direction at least with a raw water inlet 21, a pre-treatment filter element 22, a booster pump 3, an RO filter element 23, a post-filter element 24 and a Hall switch faucet 25, wherein the RO filter element 23 is also connected to a wastewater valve 26, and a booster pump 3 is connected in series between the pre-treatment filter element 22 and the RO filter element 23, and the shell 1 forms a receiving chamber 11, and the booster pump 3 is positioned in the receiving chamber 11.

[0036] During operation, the Hall switch faucet 25 is opened, the booster pump 3 is started, and the raw water is transported into the pre-treatment filter element 22 through the raw water inlet 21. The raw water is filtered by the pre-treatment filter element 22, and then the booster pump 3 pressurizes the medium water obtained by filtering the pre-treatment filter element 22. The medium water is pressurized and transported to the RO filter element 23. The RO filter element 23 is filtered to obtain RO pure water, which is then filtered by the post-filter element 24 and released from the Hall switch faucet 25. The waste water generated during water production is discharged outward through the waste water valve 26. The water production stops when the faucet is closed.

[0037] Compared with the prior art, the present application has the following improvements:

[0038] A vibration isolation device is provided in the accommodating chamber 11 of the housing 1. The vibration isolation device adopts a suspension design and can suspend and position the booster pump 3 in the accommodating chamber 11. Specifically, the vibration isolation device includes an airbag body 4 and a stiffness adjustment component 5. The airbag body 4 is made of elastic materials such as silicone rubber. The airbag body 4 is connected to the inner wall of the accommodating chamber 11 by bonding, snapping, bolts, etc. The airbag body 4 is formed with a mounting groove 41, and the booster pump 3 is snapped into the mounting groove 41; an air chamber 42 is formed inside the airbag body 4, and the stiffness adjustment component 5 is connected to the air chamber 42, which is used to extract or replenish the internal gas of the air chamber 42 to adjust the inflation stiffness of the airbag body 4. During operation, the airbag body 4 supports and positions the booster pump 3, blocks and suppresses the mechanical vibration transmitted to the outside world by the booster pump 3 during operation, and reduces the operating noise. In addition, according to the working pressure and specific vibration characteristics of the booster pump 3, the stiffness adjustment component 5 can inflate or evacuate the air chamber 42 to adjust the inflation stiffness of the airbag body 4, so that the inflation stiffness of the airbag body 4 is adapted to the vibration frequency of the booster pump 3, thereby achieving the best vibration isolation and noise reduction effect.

[0039] It should be noted that the inflation stiffness mentioned in this article refers to the ability of the airbag 4 to resist deformation when it is inflated. Specifically, the inflation stiffness describes the ability of the material to resist external forces when the airbag 4 is filled with gas, that is, the ability to resist the shape change caused by the vibration generated when the booster pump 3 is working. The size of the inflation stiffness depends on the gas pressure of the air chamber 42 inside the airbag 4 and the elastic properties of the material of the airbag 4. When the gas pressure in the air chamber 42 increases, the inflation stiffness of the airbag 4 will also increase accordingly, making it more adaptable to resist higher-frequency external vibrations. Conversely, when the inflation stiffness of the airbag 4 decreases, the ability of the airbag 4 to resist lower-frequency vibrations is improved.

[0040] Compared with the prior art technical solution of "arranging soft rubber pads and pump casing on the booster pump 3 to isolate and reduce noise", the advantages of the above technical solution of the present application are:

[0041] First, the airbag body 4 is selected as the supporting structure to suspend and position the booster pump 3. Compared with the soft rubber pad and the pump shell, the elasticity of the airbag body 4 is more significant. When it contacts the booster pump 3, the housing 1 or other water purification components, its deformation degree is greater, thereby achieving a closer fit with the booster pump 3, the housing 1 or other water purification components. This tight fit not only improves the stability of the overall structure, but also can effectively reduce the additional noise caused by the looseness of components. In addition, since the airbag body 4 is filled with air, the air can play an additional buffering role and enhance the vibration isolation effect. Therefore, during operation, the airbag body 4 can more effectively absorb and disperse the vibration energy generated by the booster pump 3 when it is working, effectively suppress and reduce the mechanical vibration transmitted to the outside world (i.e., other components of the water purification waterway 2 or the housing 1) when the booster pump 3 is working, and reduce the noise generated when the water purification system is working, thereby deeply improving the user experience.

[0042] Secondly, since the air chamber 42 can be inflated or evacuated through the stiffness adjustment component 5, the inflation stiffness of the airbag 4 can be accurately adjusted according to the vibration characteristics of the booster pump 3, so that the airbag 4 can more effectively absorb and disperse the vibration energy, reduce vibration transmission and noise generation, and ensure that the airbag 4 can always maintain good vibration isolation performance under vibrations of different frequencies. Therefore, this design can achieve wide-frequency precise vibration isolation, handle complex vibration environments, and significantly improve the noise reduction effect.

[0043] Further, in this embodiment, the inner wall of the mounting groove 41 extends outward to form a plurality of positioning gas ribs 411, which are used to abut the booster pump 3 to position the booster pump 3, and at the same time, the plurality of positioning gas ribs 411 are spaced apart from each other to form a plurality of heat dissipation channels 412. Through the above scheme, the positioning gas ribs 411 extend outward and abut the booster pump 3, which can not only provide a more stable and accurate positioning for the booster pump 3, but also enhance the structural strength of the mounting groove 41 and the airbag body 4, so that the mounting groove 41 and the airbag body 4 can maintain a complete structural form under a severe vibration working environment, continuously fit and contact the booster pump 3, and improve vibration isolation stability. In addition, the positioning gas ribs 411 are spaced apart from each other to form heat dissipation channels 412, which can provide a good heat dissipation environment for the booster pump 3, prevent the airbag body 4 from excessively fitting the booster pump 3, and during the operation of the booster pump 3, the heat generated can be quickly dissipated to the surrounding environment through the heat dissipation channels 412, avoiding the overheating problem caused by heat accumulation, ensuring the long-term stable operation of the booster pump 3, and extending the service life.

[0044] In order to increase the water flow rate of the water purifier and facilitate water collection, the existing water purifier has been improved on the basis of the original reverse osmosis water purification process, and the small flux reverse osmosis membrane has been changed to a large flux reverse osmosis membrane, and the booster pump 3 has been changed to a corresponding large flux booster pump 3. Although this process meets the flow rate requirements of the water purifier, the large flux booster pump 3 has a larger volume, mass and working intensity than the original booster pump 3, so that its working vibration also increases with the increase of its flux. At the same time, in order to adapt to smooth exhaust, the large flux booster pump 3 is usually positioned in the water purifier in a vertical form, that is, in a vertical form, which increases the difficulty of vibration isolation and noise reduction of the booster pump 3 of the water purifier.

[0045] In this regard, in order to meet the vibration isolation and noise reduction requirements of the existing water purifiers using a vertical large-flux booster pump 3, this application optimizes and improves the implementation structure of the airbag body 4 and the connection method between the airbag body 4 and the booster pump 3, specifically:

[0046] The booster pump 3 is vertically arranged in the accommodating chamber 11. The booster pump 3 includes a vertically extending pump body 31. A pump head 32 is connected to the bottom end of the pump body 31. A waterway port 33 is arranged on the pump head 32. The waterway port 33 is connected to a waterway pipe 34. The waterway port 33 includes a water inlet port and a water outlet port. The waterway pipe 34 includes a water inlet pipe connected to the water inlet port and a water outlet pipe connected to the water outlet port. The airbag body 4 includes a bag seat 43. The bag seat 43 is positioned at the bottom of the accommodating chamber 11. The mounting groove 41 is formed on the bag seat 43. One end of the bag seat 43 away from the bottom of the accommodating chamber 11 is longitudinally extended to form a supporting bag plate 44. The supporting bag plate 44 is connected to the side wall of the accommodating chamber 11 and is provided with a hanging piece 45. The pump head 32 of the booster pump 3 is snap-fitted and positioned in the mounting groove 41. The pump body 31 thereof is connected to the hanging piece 45. For the purpose of vibration isolation and noise reduction, the suspension piece 45 is preferably made of elastic material such as silicone, rubber, etc., and is arranged on the support bag plate 44 by bonding or integral molding. In this embodiment, the pump body 31 is directly bonded to the suspension piece 45 by strong glue. In addition to bonding, a clamping sleeve or a clamping hoop can also be provided on the suspension piece 45, and the pump body 31 can be detachably connected to the pump body 31 through the clamping sleeve or the clamping hoop.

[0047] When the water purification system adopts a large flux reverse osmosis process, that is, a large flux booster pump 3 is arranged vertically and positioned in the accommodating chamber 11 of its housing 1, the above-mentioned airbag body 4 structure can be used to effectively isolate and reduce the noise of the large flux booster pump 3. When working, the pump head 32 of the pump body 31 is snap-fitted and positioned in the mounting groove 41 of the bladder seat 43, and the bladder seat 43 is used as the main supporting structure to support the booster pump 3 as a whole. At the same time, the bladder seat 43 extends longitudinally to form a supporting bladder plate 44, and is connected to the side wall of the accommodating chamber 11. The pump body 31 of the booster pump 3 is connected by the suspension sheet 45 on the supporting bladder plate 44. This design not only provides a stable supporting structure, but also disperses the weight of the booster pump 3 by means of segmented suspension, avoiding the problem of local overpressure of the airbag body 4 caused by excessive force on a single point, and ensuring that the airbag body 4 has good elasticity to absorb vibration and reduce noise. In addition to the above benefits, the segmented suspension method is adopted to "disperse the weight of the booster pump 3 and reduce the average pressure of the booster pump 3 on the airbag 4", and can also effectively reduce the inflation resistance when "the stiffness adjustment component 5 replenishes gas in the air chamber 42 of the airbag 4", and can avoid the situation where "the stiffness adjustment component 5 extracts gas from the air chamber 42 of the airbag 4, and the air bag 4 is under excessive pressure, causing excessive gas overflow from the air chamber 42". It improves the suction accuracy of the stiffness adjustment component 5 on the air chamber 42, and makes the inflation stiffness adjustment process of the airbag 4 more precise.

[0048] In order to further enhance the vibration isolation and noise reduction capability of the vertical large-flux booster pump 3, in this embodiment, the end of the support bladder plate 44 away from the bladder seat 43 extends outward to form a positioning bladder plate 46, and the positioning bladder plate 46 is formed with a positioning groove 47, and the end of the pump body 31 away from the pump head 32 is snap-fitted and positioned in the positioning groove 47. By providing the positioning bladder plate 46 and the positioning groove 47, the booster pump 3 can be longitudinally and bidirectionally positioned in cooperation with the bladder seat 43 and the mounting groove 41, thereby reducing the additional vibration of the booster pump 3 caused by improper installation or looseness.

[0049] Furthermore, in order to enhance the support and bottom vibration isolation performance of the vertical booster pump 3. In this embodiment, a limiting groove 12 is formed at the bottom of the accommodating chamber 11, and the bottom of the airbag body 4, that is, the bag seat 43, is positioned in the limiting groove 12, and the bottom of the airbag body 4 is horizontally and laterally limited by the limiting groove 12. By setting the limiting groove 12 to horizontally and laterally limit the bag seat 43, that is, the bottom of the airbag body 4, the displacement range of the bottom of the airbag body 4 during the vibration process can be limited, thereby reducing the transmission of vibration energy to other parts of the water purification system, and ensuring that the airbag body 4 maintains a certain shape and rigidity during the vibration process, so as to better absorb and disperse the vibration energy, improve the overall vibration isolation performance, and help reduce the noise and vibration of the booster pump 3 when it is working.

[0050] In addition to the vibration and noise generated by the body of the booster pump 3, there is also vibration of the pump inlet and outlet pipes caused by the vibration of the body of the booster pump 3, as well as vibration of the inlet and outlet pipes of the booster pump 3 caused by the pulse pressurization process. Since the inlet and outlet pipes are generally connected to other components, this vibration is extremely easy to be transmitted to the connected components. This will not only cause resonance of other components, but also cause water leakage and reliability risks at the interface. Therefore, it is necessary to reduce the vibration of the inlet and outlet pipes of the booster pump 3, which helps to reduce noise and improve reliability. In this regard, in the present embodiment, the mounting groove 41 is provided with a soundproof groove 413, and the inner wall of the soundproof groove 413 at least partially abuts the waterway port 33 and the waterway pipe 34. The design of the sound insulation groove 413 enables the water port 33 and the water pipe 34 to fit in contact with the airbag body 4, forming an integrated connection between the airbag body 4, the water port 33 and the water pipe 34. The airbag body 4 absorbs and isolates the vibration of the booster pump 3 body and its inlet and outlet pipes, significantly reducing the impact of these vibrations on other connecting components, thereby reducing resonance, reducing the risks of loose interfaces and water leakage caused by vibration, and improving the overall reliability and service life of the system.

[0051] The structural composition and connection method of the "stiffness adjustment component 5 adjusts the inflation stiffness of the airbag body 4" solution are specifically introduced below.

[0052] The airbag body 4 is provided with an air inlet nozzle 48 and an air outlet nozzle 49 respectively connected to the air chamber 42. The stiffness adjustment component 5 includes an air pump 51 and an exhaust valve 52. The output end of the air pump 51 is connected to the air inlet nozzle 48 for the inside of the air chamber 42. The input end of the exhaust valve 52 is connected to the exhaust nozzle 49 for exhausting the gas in the air chamber 42. During operation, when the flux of the booster pump 3 increases, the working pressure increases, and the vibration frequency generated becomes higher, the air pump 51 can supplement gas into the air chamber 42 of the airbag body 4 through the air inlet nozzle 48 to inflate the air chamber 42 and improve the stiffness of the airbag body 4; when the flux of the booster pump 3 decreases, the working pressure decreases, and the vibration frequency generated becomes lower, the exhaust valve 52 can exhaust the air chamber 42 of the airbag body 4 through the exhaust nozzle 49 to deflate and shrink the air chamber 42, thereby reducing the stiffness of the airbag body 4, so that the airbag body 4 can adapt to the vibration suppression requirements under different working conditions.

[0053] The above-mentioned implementation structure of "inflating the airbag 4 through the air pump 51 and exhausting the airbag 4 through the exhaust valve 52" is not only simple and reliable in structure, but also the functions of the stiffness adjustment component 5 to supplement gas and extract gas from the airbag 4 are independently realized by the air pump 51 and the exhaust valve 52 respectively, which can improve the adjustment response capability of the inflation stiffness of the airbag 4, so that the inflation stiffness of the airbag 4 can follow the changes in the working pressure of the booster pump 3, thereby realizing rapid response adjustment.

[0054] In order to improve the structural stability of the airbag body 4 during the process of filling and discharging the gas in the air chamber 42, the present embodiment optimizes the positions of the air inlet nozzle 48 and the air outlet nozzle 49: the air inlet nozzle 48 is arranged at the bottom of the airbag body 4 (i.e., the bottom of the airbag seat 43) and communicates with the bottom end of the air chamber 42, and the air outlet nozzle 49 is arranged at the top of the airbag body 4 (i.e., the top of the positioning airbag plate 46) and communicates with the top end of the air chamber 42.

[0055] Through the above design, the air inlet is located at the bottom of the airbag body 4 and is connected to the bottom of the air chamber 42, so that when the air pump is inflated, the gas can directly and efficiently enter the bottom of the air chamber 42. In view of the rising characteristics of the gas, the bottom air intake helps the gas to be evenly distributed in the air chamber 42, thereby reducing the formation of bubbles and dead corners. In addition, the bottom air intake design can ensure that the bottom of the airbag body 4 is supported and fixed first during the inflation process, which helps to establish a stable bottom structure at the beginning of inflation, reduce the bottom shaking or deformation caused by uneven inflation, and improve the vibration isolation stability of the airbag body 4; and the design that the air outlet is located at the top of the airbag body 4 and is connected to the top of the air chamber 42 enables the exhaust valve 52 to preferentially exhaust the gas at the top of the air chamber 42 when exhausting. Since the gas in the air chamber 42 is usually distributed in a state of more at the top and less at the bottom (especially during the inflation process), the top exhaust helps to reduce the overall air pressure in the air chamber 42 more quickly. At the same time, the top exhaust can also reduce the disturbance of the gas to other parts of the air chamber 42 during the exhaust process, and maintain the stability of the air chamber 42.

[0056] In addition, in this embodiment, a one-way valve is connected in series between the air inlet nozzle 48 and the air pump 51 to allow gas to enter the air chamber 42 in one direction. When the air pump 51 is working, shut down or fails, the one-way valve can prevent the gas in the air chamber 42 from flowing back to the air pump 51, which helps to maintain the air pressure inside the airbag body 4 stable, improve the inflation efficiency and the stiffness adjustment accuracy of the airbag body 4.

[0057] Furthermore, in order to achieve automatic control, the water purification system provided in this embodiment also includes a control component 6, which includes a stiffness detector 61 and a controller 62; the stiffness detector 61 is connected to the airbag body 4 to detect the inflation stiffness of the airbag body 4; the signal input end of the controller 62 is connected to the booster pump 3 and the stiffness detector 61; the signal output end of the controller 62 is connected to the stiffness adjustment component 5, which is used to control the stiffness adjustment component 5 to extract or replenish gas from the air chamber 42.

[0058] During operation, the boosting pump 3 can be connected through the controller 62 to read the motor speed or current of the boosting pump 3, and monitor the working pressure of the boosting pump 3. At the same time, the stiffness detector 61 is connected to the airbag 4 and the controller 62 to detect the stiffness of the airbag 4, and the detection data is transmitted to the controller 62 in real time. The controller 62 performs data processing and logical judgment. According to the working pressure of the boosting pump 3 and the actual stiffness of the airbag 4, the controller 62 transmits a signal to the stiffness adjustment component 5 to drive the stiffness adjustment component 5 to replenish or extract gas from the air chamber 42 of the airbag 4, adjust the inflation stiffness of the airbag 4, and adjust the stiffness of the airbag 4 to the preset value of the stiffness of the "different working pressure conditions of the boosting pump 3", thereby realizing automatic control of the stiffness of the airbag 4.

[0059] Specifically, the selection of the stiffness detector 61 is diverse. In this embodiment, the stiffness detector 61 preferably uses an air pressure sensor. When working, the air pressure sensor is connected to the air chamber 42 of the airbag 4, and the inflation stiffness of the airbag 4 is evaluated by detecting the air pressure value in the air chamber 42. Compared with other detection structures, the air pressure sensor can measure the air pressure value in the air chamber 42 in real time and accurately, and the air pressure value is directly related to the inflation state and stiffness of the airbag 4. Therefore, by monitoring the change of the air pressure value in the air chamber 42, the inflation stiffness of the airbag 4 can be more accurately evaluated indirectly. In addition, in order to improve the accuracy and stability of automatic control and stiffness adjustment of the airbag 4, and prevent the failure of a single sensor, resulting in unsatisfactory system noise reduction effect. The stiffness detector 61 may also include a deformation sensor and a displacement sensor. When working, the deformation sensor or the displacement sensor can be set on the outer wall of the airbag 4 to assist in evaluating the inflation stiffness of the airbag 4 by detecting the local deformation and displacement of the airbag 4 during inflation and deflation.
