Description

Technical Field

[0001] This invention relates to the technical field of water treatment equipment, specifically a ceramic filter element used in ultrafiltration water purifiers. Background Technology

[0002] Tap water may be subject to secondary pollution during transportation. Additionally, some homes use secondary water supply systems, resulting in stagnant water and other issues, making the tap water quality highly susceptible to contamination. To ensure the safety and health of household water, water purifiers are typically installed at home to treat tap water, removing impurities, heavy metals, bacteria, viruses, and other pollutants.

[0003] Existing water purifiers, designed for direct drinking, employ multiple filter elements, including PP cotton filters, activated carbon filters, and RO reverse osmosis membrane filters. These multiple filters treat tap water through adsorption and filtration. During this process, contaminants from the tap water adhere to the filter surface. To prevent re-contamination of the water and to avoid affecting water production efficiency, the filters need to be cleaned regularly. However, the structure or surface of the filter is grid-like, making it difficult to remove contaminants adhering to the gaps through rinsing and soaking, thus hindering effective cleaning of the filter. Summary of the Invention

[0004] The present invention aims to provide a ceramic filter element for use in ultrafiltration water purifiers, in order to solve the technical problem that the filter elements of household water purifiers in the prior art cannot be effectively cleaned due to their structure.

[0005] This invention provides the following basic solution:

[0006] A ceramic filter element used in an ultrafiltration water purifier includes a first membrane layer and a second membrane layer connected together. The materials of the first membrane layer and the second membrane layer include pure alumina. A chamber is provided between the first membrane layer and the second membrane layer, and the direction of water filtration is from the side of the first membrane layer and the second membrane layer away from the chamber to the chamber.

[0007] The beneficial effects of the basic scheme:

[0008] During use, tap water flows through the first or second membrane layer into the chamber. The water inside the chamber is the filtered purified water. Contaminants in the tap water are blocked by the first and second membrane layers, thus filtering and removing contaminants from the tap water. In this solution, pure alumina is used and fired at high temperature. The first and second membrane layers are uniform and fine with extremely low surface roughness. Compared with existing filter cartridges, this minimizes the accumulation of contaminants on the filter cartridge surface, preventing contaminants from adhering to and accumulating on the first and second membrane layers.

[0009] Compared to existing filter cartridges, this design features smooth surfaces for both the first and second membrane layers, with the filtered contaminants located on surfaces far from the chamber, making these surfaces easier to clean. This design reduces contaminant adhesion and accumulation while increasing the ease and efficiency of cleaning, thereby improving the surface cleanliness of both the first and second membrane layers and ultimately achieving effective cleaning of household water purifier filter cartridges.

[0010] Furthermore, the first and second membrane layers are annular in shape.

[0011] Beneficial effects: This design increases the contact area between the first and second membrane layers and tap water, thereby improving water production efficiency, that is, increasing the filtration rate of tap water.

[0012] Furthermore, it also includes an inner ring and an outer ring. The inner ring connects the inner rings of the first membrane layer and the second membrane layer, and the outer ring connects the outer rings of the first membrane layer and the second membrane layer. The inner ring has an inner outlet that communicates with the chamber.

[0013] Beneficial effects: During use, tap water flows through the first or second membrane layer into the chamber and then flows out from the inner outlet. The water flowing out from the inner outlet is the filtered purified water. The inner and outer rings connect and support the first and second membrane layers, while the inner outlet concentrates the purified water, facilitating the subsequent installation of the water purifier's outlet.

[0014] Furthermore, it also includes an inner ring and an outer ring. The inner ring connects the inner rings of the first membrane layer and the second membrane layer, and the outer ring connects the outer rings of the first membrane layer and the second membrane layer. The outer ring has an outer outlet that communicates with the chamber.

[0015] Beneficial effects: During use, tap water flows through the first or second membrane layer into the chamber and then flows out through the outer outlet. The water flowing out of the outer outlet is the filtered purified water. The inner and outer rings connect and support the first and second membrane layers. The outer outlet concentrates the purified water, facilitating the subsequent installation of the water purifier's outlet. Furthermore, the outer outlet's location on the outer ring makes cleaning the outlet easier when cleaning the filter cartridge.

[0016] Furthermore, there are multiple external outlets, which are evenly distributed on the outer ring.

[0017] Beneficial effects: This design allows for centralized water output from the purified water source while ensuring smooth drainage.

[0018] Furthermore, a support body is provided inside the cavity, which divides the cavity into multiple sub-cavities, and the sub-cavities are connected to the external outlet.

[0019] Beneficial effects: This design enhances the stability of the connection between the first and second membrane layers.

[0020] Furthermore, the external outlet corresponds one-to-one with the sub-chamber.

[0021] Beneficial effects: This design allows for the parallel design of multiple filtration channels, improving water production efficiency.

[0022] Furthermore, the cross-sectional area of ​​the sub-chamber gradually decreases from the outer outlet inwards.

[0023] Beneficial effects: This design ensures smooth drainage of purified water, reduces water accumulation, avoids the formation of stagnant water, and prevents secondary pollution of the purified water. Attached Figure Description

[0030] The following detailed description illustrates the specific implementation method:

[0031] The reference numerals in the accompanying drawings include: first membrane layer 1, second membrane layer 2, chamber 3, inner ring 4, outer ring 5, outer outlet 6, and support body 7.

[0032] Example 1

[0033] Ceramic filter cartridges used in ultrafiltration water purifiers, as shown in the attached image. Figure 1 As shown, it includes a first film layer 1 and a second film layer 2 connected together. The materials of the first film layer 1 and the second film layer 2 include pure alumina. In this embodiment, the first film layer 1 and the second film layer 2 are made of pure alumina by high-temperature firing.

[0034] A chamber 3 is provided between the first membrane layer 1 and the second membrane layer 2. The first membrane layer 1 and the second membrane layer 2 are annular and sheet-like structures. An inner ring 4 is also included, connecting the inner rings of the first membrane layer 1 and the second membrane layer 2; that is, the first membrane layer 1 and the second membrane layer 2 are connected through the inner ring 4. In other embodiments, the inner ring 4 is not provided, and an outer ring 5 is included, connecting the outer rings of the first membrane layer 1 and the second membrane layer 2; that is, the first membrane layer 1 and the second membrane layer 2 are connected through the inner ring 4.

[0035] In this embodiment, the first membrane layer 1, the second membrane layer 2, and the inner ring 4 are integrally formed. The direction of filtered water is from the side of the first membrane layer 1 and the second membrane layer 2 away from the chamber 3 into the chamber 3.

[0036] In this design, pure alumina is used for high-temperature firing, resulting in a uniform and fine first membrane layer 1 and a very low surface roughness for both the second and third membrane layers. Compared to existing filter cartridges, this design minimizes the adhesion and accumulation of contaminants on the filter surface. Furthermore, the surfaces of the first and second membrane layers are smooth, and the filtered contaminants are located on the surface furthest from the chamber 3, making this side easier to clean. This design reduces contaminant adhesion and accumulation while increasing the convenience and efficiency of cleaning, thereby improving the surface cleanliness of the first and second membrane layers and achieving effective cleaning of household water purifier filter cartridges.

[0039] Used in ceramic filter elements of ultrafiltration water purifiers, such as... Figure 2 As shown, it also includes an outer ring 5, which connects the outer ring of the first membrane layer 1 and the second membrane layer 2. The outer ring 5 has multiple external outlets 6 that communicate with the chamber 3, and these external outlets 6 are evenly distributed on the outer ring 5. In other embodiments, the outer ring 5 does not have external outlets 6, and the inner ring 4 has an inner outlet that communicates with the chamber 3.

[0040] In this embodiment, the first membrane layer 1, the second membrane layer 2, the inner ring 4, and the outer ring 5 are integrally formed. In use, tap water moves through the first membrane layer 1 or the second membrane layer 2 into the chamber 3, and flows out from the outer outlet 6 along the chamber 3. The water flowing out from the outer outlet 6 is the filtered purified water.

[0041] In this design, the inner ring 4 and outer ring 5 connect and support the first membrane layer 1 and the second membrane layer 2. The external outlet 6 concentrates the purified water, facilitating the subsequent installation of the water purifier's outlet. Furthermore, the external outlet 6 is located on the outer ring 5, making it easy to clean when cleaning the filter cartridge.

In this embodiment, the first membrane layer 1, the second membrane layer 2, the support body 7, the inner ring 4, and the outer ring 5 are integrally formed.

[0048] In this design, the support 7 enhances the stability of the connection between the first membrane layer 1 and the second membrane layer 2. Simultaneously, the parallel design of multiple filtration channels effectively improves water production efficiency.

[0049] Example 5

[0050] The difference between this embodiment and embodiment four is that:

[0051] Used in ceramic filter elements of ultrafiltration water purifiers, such as... Figure 5 As shown, the cross-sectional area of ​​the sub-chamber gradually decreases from the outer outlet 6 inwards. This design ensures smooth drainage of purified water, reduces water accumulation, prevents the formation of stagnant water, and avoids secondary pollution of the purified water.
