Description

Technical Field

[0001] This invention relates to a noise reduction structure and a water purification system integrated within a filter assembly. Background Technology

[0002] Filter products with booster pumps on the market generate high-frequency pulsed water pressure when the booster pump produces water, which acts on the filter membrane through the water path. At the same time, the water pressure backflow acts on the RO pump, producing relatively obvious noise or abnormal sounds. Existing structures, even with the addition of some soft-fixed vibration reduction measures, cannot effectively reduce the overall operating noise of the machine, resulting in a poor customer experience and failing to meet expectations. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, the purpose of this invention is to provide a noise reduction structure and a water purification system integrated in a filter element assembly.

[0004] This invention is achieved through the following technical solution: a noise reduction structure integrated within a filter element assembly, comprising a filter element assembly and a noise reduction structure integrated within the filter element assembly, wherein the filter element assembly includes an inlet and an outlet; the noise reduction structure includes a buffer chamber and an elastic buffer pad, wherein the elastic buffer pad is installed within the buffer chamber to divide the cavity into a first cavity and a second cavity, the first cavity being connected to the inlet to form an inlet water passage, and the second cavity enclosing the elastic buffer pad to form a sealed space.

[0005] Preferably, the filter element assembly is installed in the filter element fixing seat, and the filter element assembly includes a body and a filter membrane, with the filter membrane installed in the body.

[0006] Preferably, the elastic cushioning pad comprises one or more elastic materials such as silicone, silicone rubber, rubber, spring, PVC, EVA, POE, TPES, and foam.

[0007] Preferably, the elastic buffer pad is fixedly disposed within the body of the filter element assembly to form a first seal.

[0008] Preferably, a sealing gasket is also provided on the outside of the buffer chamber, and the sealing gasket cooperates with the body of the filter element assembly to form a second seal.

[0009] Preferably, the elastic buffer pad includes a first buffer member and a second buffer member, wherein the first buffer member divides the cavity into a first cavity and a second cavity, the first cavity is connected to the water inlet to form the water inlet channel, and the second cavity encloses the first buffer member and the second buffer member to form a sealed space.

[0010] Preferably, the second buffer is a spring.

[0011] Preferably, the first buffer element is arranged in an arc shape.

[0012] The present invention also provides a water purification system, including an external water tank assembly, a housing assembly, and a pure water tank assembly, wherein the housing assembly is provided with any of the noise reduction structures described above.

[0013] Preferably, the housing assembly further includes a water channel plate assembly, which is connected to the water channel of the filter element assembly, and a noise reduction structure is provided in the water inlet channel of the water channel plate assembly.

[0014] This invention creates a noise reduction structure by incorporating a pulse-reducing structure within the filter element assembly. In this way, the high-pulse water flow from the booster pump outlet directly impacts the buffer chamber and elastic buffer pad within the filter element assembly through the filter element assembly's inlet. The elastic medium deforms under the impact of the water flow and rebounds, causing the high-pulse water flow to be mixed and its pulse amplitude reduced within the buffer chamber. The impact amplitude of the water flow on the dense filter membrane is effectively reduced. Simultaneously, the backflow water pulse is also buffered by the buffer chamber and elastic buffer pad, preventing it from directly impacting the high-speed booster pump, thereby effectively reducing the overall machine noise.

[0025] Reference manual attached Figure 1 To be continued Figure 3 A water purification system with a noise reduction structure includes an outer water tank assembly 1, a tank assembly 2, and a pure water tank assembly 3. The outer water tank assembly 1 is used to hold raw water. After being filtered by the tank assembly 2, the raw water flows into the pure water tank assembly 3 for use by the user. Furthermore, the water purification system also includes a front cover assembly 4, which forms a pure water outlet for the user to collect pure water.

[0026] Furthermore, the aforementioned housing assembly 2 includes a water channel plate assembly 21 and a filter element assembly 22. Of course, a corresponding pump can also be installed within the housing assembly, which is existing technology and will not be elaborated upon here. The water channel plate assembly 21 is connected to the filter element assembly 22 via water channels. The filter element assembly 22 is installed on the filter element mounting base 220. The filter element assembly 22 includes a filter membrane 221 and a body 222. The filter membrane 221 is installed on the body 222. The water channel plate assembly is also connected to the filter element mounting base. In addition, the filter element assembly 22 forms an inlet water channel 223. Raw water flows into the filter membrane 221 through this inlet water channel 223 for filtration. The filtered water then flows back into the water channel plate assembly 21. Simultaneously, a noise reduction structure is also provided within the inlet water channel 223, and this noise reduction structure is integrated within the filter element assembly 22. Specifically, the filter element assembly 22 includes an inlet 224 and an outlet 225. The outlet 225 is connected to the water passage of the water circuit board assembly 21. The inlet or outlet can be a quick-connect plug or a straight pipe interface. The noise reduction structure is arranged in the inlet water passage 223. The noise reduction structure includes a buffer chamber 211 and an elastic buffer pad 212. The elastic buffer pad 212 is installed in the buffer chamber 211 and fixedly arranged in the body 222. Meanwhile, the buffer chamber 211 is arranged in the inlet water passage 223. Preferably, the elastic buffer pad 212 includes one or more elastic materials such as silicone, silicone rubber, rubber, spring, PVC, EVA, POE, TPES, and foam. The noise reduction structure is formed by filling the buffer chamber with elastic buffer material.

[0027] The aforementioned elastic buffer pad 212 is fixed inside the body 222 to form a first seal. Simultaneously, the elastic buffer pad 212 can divide the buffer chamber 211 into two cavities: a first cavity 2111 and a second cavity 2112. The first cavity 2111 communicates with the water inlet 224 to form a complete water flow channel (i.e., water inlet path 223). The second cavity 2112 can enclose the buffer pad to form a sealed space. During operation, the elastic buffer pad can freely deform and expand within the cavity under pressure. Furthermore, a sealing gasket 217 is also provided on the outside of the buffer chamber 211. The sealing gasket 217 is fixed inside the filter element assembly 22 and cooperates with the body to form a second seal.

[0028] This invention creates a noise reduction structure by incorporating a pulse-reducing structure within the filter element assembly. In this way, the high-pulse water flow from the booster pump outlet directly impacts the buffer chamber 211 and elastic buffer pad 212 within the filter element assembly via the inlet 224. The elastic medium deforms under the impact of the water flow and rebounds, causing the high-pulse water flow to be mixed and its pulse amplitude reduced within the buffer chamber. This effectively reduces the amplitude of the water flow impacting the dense filter membrane. Simultaneously, the backflow pulse is also buffered by the buffer chamber 211 and elastic buffer pad 212, preventing it from directly impacting the high-speed booster pump, thereby effectively reducing the overall noise of the machine.

[0029] See attached document Figure 4 This is another embodiment of the present invention. In this embodiment, the elastic buffer pad 212 includes a first buffer member 2121 and a second buffer member 2122. The first buffer member 2121 divides the cavity into a first cavity 2111 and a second cavity 2112. The first cavity 2111 communicates with the water inlet 224 to form a water inlet channel 223. The second cavity 2112 encloses the first buffer member 2121 and the second buffer member 2122 to form a sealed space. The elastic buffer pad 212 is impacted by the water flow and undergoes buffering and rebound deformation. The rebound deformation of the adjacent first and second buffer members can effectively further reduce the water flow amplitude in the water purification system, effectively reduce water flow pulses, and prevent the backflow water flow pulses from directly impacting the high-speed booster pump, thereby effectively reducing the noise of the water purification system. In a specific embodiment, the first buffer member 2121 is arranged in an arc shape, thereby forming a larger deformation amount.

[0030] See attached document Figure 5 In one specific embodiment, the second buffer 2122 is a spring, and the bottom of the first buffer 2121 has a groove. One end of the spring abuts against the groove, and the other end abuts against the housing inside the buffer chamber. Thus, the purification system of the present invention integrates a pulse-reducing structure within the filter assembly by installing an elastic buffer pad inside the buffer chamber, thereby effectively reducing the noise of the entire machine. Of course, refer to the attached... Figure 6 In addition to integrating the noise reduction structure into the water inlet channel of the filter element assembly, in another embodiment, the noise reduction structure can also be integrated into the water inlet channel 218 of the water channel plate assembly 21, thereby further effectively reducing the noise of the whole machine. The noise reduction structure of the present invention can be applied alone to a channel with a water channel, or the corresponding buffer chamber and elastic buffer material can be integrated into the water channel plate assembly or the filter element assembly in an integrated structure manner.

[0031] The foregoing description illustrates and describes preferred embodiments of the present invention. As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
