[0033] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0034] Referring to Figures 1 and 2, a filter media carrier device according to a preferred embodiment of the present invention is shown, comprising:

[0035] The first supporting component 1 has a first flow channel 11 and a water passage 12. The first flow channel 11 extends along the axial direction of the first supporting component 1. The first axial end of the first flow channel 11 is closed and the second axial end of the first flow channel 11 is open. The first flow channel 11 is used to support filter media. The water passage 12 is located on the side wall of the first supporting component 1 and is connected to the first flow channel 11.

[0036] The second supporting component 2 is sleeved on the first supporting component 1. A second flow channel 3 is formed between the inner side wall of the second supporting component 2 and the outer side wall of the first supporting component 1. The second flow channel 3 is connected to the water hole 12 to connect the second flow channel 3 to the first flow channel 11. The second flow channel 3 is parallel to the first flow channel 11. The first axial end of the second flow channel 3 is closed, and the second axial end of the second flow channel 3 is open.

[0037] The water inlet cap 4 is located on the axial end of the second supporting component 2. The water inlet cap 4 covers the axial second end of the second flow channel 3 to force water flow through the water passage 12 for exchange. The water inlet cap 4 has a water inlet channel 41 for connecting the second flow channel 3 and an external pure water supply device; and

[0038] The water outlet end cap 5 is located on the axial end of the first bearing component 1. The water outlet end cap 5 covers the second axial end of the first flow channel 11 to force the water flow to pass through the filter media for exchange, simulating the full interception effect of the filter media in a real scenario. The water outlet end cap 5 and the water inlet end cap 4 are respectively placed at the two axial ends of the filter media bearing device. The water outlet end cap 5 has a water outlet flow channel 51, which is connected to the first flow channel 11.

[0039] The filter media carrier device of this invention, through the internal and external dual-channel structure composed of the first flow channel 11 and the second flow channel 3 and the design of the lateral water passage hole 12, reproduces the multi-directional flow field inside the reverse osmosis membrane with low-cost pure water testing. At the same time, it avoids the use of real membrane elements, significantly reducing testing costs and improving testing accuracy. Specifically, when the filter media needs to be tested for performance, the water output from the pure water supply device is transported to the second flow channel 3 through the inlet flow channel 41, then radially permeates to the first flow channel 11 through the water passage hole 12, and is then filtered by the filter media and discharged from the outlet flow channel 51, forming a multi-directional flow field that combines radial and axial flow. This flow field simulates the multi-directional flow field of the central tube of the reverse osmosis membrane. This multi-directional flow field reproduces the multi-directional diffusion and convergence effect of water flow in the central tube of the reverse osmosis membrane, which can improve the testing accuracy.

[0040] Referring to Figure 2, in one embodiment, the filter media carrier further includes:

[0041] The first barrier component 7 is located between the outlet end cap 5 and the filter media located in the first flow channel 11. The first barrier component 7 covers the opening of the outlet flow channel 51 near the first flow channel 11. The first barrier component 7 allows pure water filtered by the filter media to flow into the outlet flow channel 51. Simultaneously, the first barrier component 7 also intercepts the first particulate matter released by the filter media. Because the first barrier component 7 is located between the filter media and the outlet flow channel 51, it can effectively intercept particles (such as powder, debris, etc.) detached from the filter media, preventing them from entering the outlet end cap 5 or external testing equipment, thus ensuring test accuracy. Furthermore, the first barrier component 7 only allows filtered pure water to flow into the outlet flow channel 51, blocking undissolved or insufficiently adsorbed impurities, allowing the test results to focus more on the performance of the filter media itself (such as adsorption efficiency, flux, etc.). In addition, regardless of whether the filter media is granular, powdery, or fragile, the first barrier component 7 can prevent it from leaking or clogging the outlet flow channel 51, ensuring the filter media testing efficiency and extending the service life of the filter media support device.

[0042] Referring to Figure 2, in one embodiment, the filter media carrier further includes:

[0043] The second barrier component 8 is located inside the water outlet channel 51. It supplies pure water filtered by the filter media to the outside of the channel 51. Simultaneously, it intercepts second particles released by the filter media; these second particles have a smaller particle size than the first particles. By adding the second barrier component 8, the accuracy and reliability of filter media performance testing are further optimized. Specifically, the second barrier component 8 intercepts smaller particles (the second particulate matter), forming a multi-level protection with the first barrier component 7 (which intercepts larger particles), ensuring pure water output and preventing filter media detachment of different particle sizes from interfering with test results. Furthermore, small particles are intercepted by the second barrier component 8 at the front end of the water outlet channel 51, preventing them from entering the downstream pipes or testing equipment, reducing the risk of blockage, and extending the device's service life.

[0044] In one embodiment, both the first barrier component 7 and the second barrier component 8 can be nonwoven fabric.

[0045] Of course, in other embodiments, the first barrier component 7 and the second barrier component 8 can both be structures made of cotton. The use of cotton for the first barrier component 7 and the second barrier component 8 can effectively intercept the particulate matter released by the filter material during the test and prevent it from entering the water outlet channel 51 or external testing equipment.

[0046] In one embodiment, the cotton material is preferably polypropylene cotton, which has high porosity, good mechanical strength and chemical stability, and can balance high-efficiency filtration and durability. In addition, polypropylene cotton is a common industrial material, which helps to control production costs while ensuring filtration effect.

[0047] Referring to Figure 2, in one embodiment, the water outlet channel 51 includes:

[0048] The first water outlet section 511 is connected to the first flow channel 11; and

[0049] The second water outlet section 512 and the first water outlet section 511 are arranged one after another along the water outlet direction of the water outlet channel 51. The inner diameter of the second water outlet section 512 is smaller than the inner diameter of the first water outlet section 511. A limiting end is formed between the second water outlet section 512 and the first water outlet section 511. The second blocking component 8 is located inside the first water outlet section 511 and abuts against the limiting end. Thus, the stepped structure of the first outlet section 511 and the second outlet section 512 (with a smaller inner diameter in the second outlet section 512) forms a limiting end, ensuring the second barrier component 8 is securely installed and preventing displacement or detachment. Secondly, the second barrier component 8 covers the inlet of the second outlet section 512, completely intercepting particulate matter and preventing it from entering external testing equipment. In addition, the segmented flow channel design (first outlet section 511 → second outlet section 512) achieves efficient filtration within a limited space, while reducing water flow resistance and maintaining good water flow efficiency, which is beneficial for improving testing efficiency. Furthermore, the second barrier component 8 tightly abuts against the limiting end, enhancing sealing and preventing unfiltered water from flowing around, thus improving overall filtration reliability and further enhancing testing accuracy.

The inner side wall of the second limiting part 21 abuts against the outer side wall of the first bearing component 1 to ensure that the second bearing component 2 and the first bearing component 1 are tightly attached. The end of the second limiting part 21 is connected to the end of the first limiting part 13 to realize the installation and positioning of the second bearing component 2 while ensuring that the second bearing component 2 and the first bearing component 1 are reliably connected together.
