Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a CTO composite filter. Background Technology

[0002] With the improvement of people's living standards, people are paying more and more attention to water quality and hygiene. Equipping homes with water purification equipment has become a trend. Some consumers hope that drinking water contains trace elements and other minerals to provide for human absorption to a certain extent, or to provide different water qualities needed for brewing tea, coffee, etc. According to announcement number CN219885792U, a composite filter element is disclosed, including a filter bottle body, a first carbon rod containing a first mineral, and a second carbon rod containing a second mineral. Both the first and second carbon rods are disposed inside the filter bottle body. The inlet and outlet sides of the first carbon rod are connected to the outside. Outside water enters the inlet side of the first carbon rod, is filtered by the first carbon rod, dissolves the first mineral in the first carbon rod, and is discharged to the outside through the outlet side of the first carbon rod. The second carbon rod works similarly to the first carbon rod; the second mineral in the second carbon rod can be dissolved and carried away by water. The inlet side of the first carbon filter and the inlet side of the second carbon filter share the same interface; alternatively, the outlet side of the first carbon filter and the outlet side of the second carbon filter share the same interface; or, none of the four interfaces (inlet side of the first carbon filter, outlet side of the first carbon filter, inlet side of the second carbon filter, and outlet side of the second carbon filter) are shared. This invention can optionally increase the required mineral content in the water. However, the above-mentioned technology has some drawbacks, such as the cumbersome disassembly and replacement process of existing traditional filter cartridges, requiring professional personnel to operate, increasing maintenance costs and time. These shortcomings mainly stem from the fact that the traditional method did not fully consider the needs and challenges of actual operation in its design, leading to various problems during use, necessitating improvement.

Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1

[0025] Please see Figure 1-5This utility model provides a technical solution: a CTO composite filter element, including a filter element body 1, an installation block 2 installed on the left side of the filter element body 1, a protective net 4 provided on the right side of the installation block 2, a fixing block 5 installed on the right side of the filter element body 1, a rotating plate 7 provided inside the fixing block 5, a cover plate 8 installed on the right side of the rotating plate 7, a filter screen 9 installed on the right side of the cover plate 8, a pinch pad 10 installed on the right side of the cover plate 8, a soft pad 11 installed on the right side of the installation block 2, and an installation plate 12 installed on the left side of the installation block 2. The right side of the mounting plate 12 has an installation groove 13, the right side of the mounting plate 12 has a flow guide groove 14, the right side of the mounting plate 12 has a limiting plate 15, and the right side of the mounting plate 12 has a retaining pad 17. By setting up the mounting block 2, fixing groove 3, protective net 4, fixing block 5, rotating groove 6, rotating plate 7, cover plate 8, filter screen 9, pinch pad 10, soft pad 11, mounting plate 12, mounting groove 13, flow guide groove 14, limiting plate 15, limiting groove 16, and retaining pad 17, the filter element can be quickly installed and removed, improving replacement efficiency. The sliding fit between the protective net 4 and the fixing groove 3, and the symmetrical distribution of the soft pad 11, effectively prevent water flow from impacting the filter element and extend its service life. The sliding connection between the limiting groove 16 and the limiting plate 15, and the sliding connection between the retaining pad 17 and the mounting block 2, ensure the stability and sealing of the filter element during operation. These technical features work together to give the CTO composite filter element better filtration effect, longer service life, and more convenient maintenance. The protective net 4 slides inside the fixing groove 3 within the mounting block 2, and the rotating plate 7 rotates inside the fixing block 5 via the rotating groove 6, ensuring the stability and ease of installation and disassembly of the filter element. The protective net 4 also effectively blocks external impurities from entering the filter element, protecting its filtration performance. The cover plate 8 is rotatably connected to the fixing block 5 and the protective net 4. The pinch pads 10 are evenly distributed on the right side of the cover plate 8, better adapting to water flow impacts from different directions and improving filtration efficiency. The even distribution of the pinch pads 10 on the right side of the cover plate 8 provides a more comfortable operating experience for users. The soft pads 11 are symmetrically distributed on the mounting block 2. At the front and rear ends of the right side of the mounting block 2, the mounting block 2 slides inside the limiting plate 15 through the limiting groove 16. The mounting block 2 and the mounting plate 12 are slidably connected, ensuring the stability and accuracy of the filter element during installation. The sliding connection design between the mounting block 2 and the mounting plate 12 makes the installation and disassembly of the filter element more convenient and efficient. The mounting block 2 is slidably connected to the retaining pad 17. The soft pad 11 slides inside the limiting plate 15 through the limiting groove 16, ensuring the stability and firmness of the filter element during installation and effectively preventing loosening caused by vibration or impact. The mechanism of the soft pad 11 sliding inside the limiting plate 15 through the limiting groove 16 not only provides additional buffering and reduces the impact damage of water flow to the filter element, but also ensures the positional stability of the filter element during operation.

[0026] Example 2

[0027] Please see Figure 1-3 5. 6. A fixing plate 18 is installed on the right side of the mounting plate 12. The surface of the fixing plate 18 has a slot 19, and a protective cover 20 is provided on its surface. The inner wall of the protective cover 20 is fitted with protrusions 21, ensuring the stability and firmness of the filter element during installation. The protective cover 20 on the surface of the fixing plate 18 and the protrusions 21 on its inner wall further enhance the protective performance of the filter element, effectively preventing external impurities from entering and ensuring the stability and durability of the filtration effect. This design not only improves the service life of the filter element but also provides users with a safer and more reliable user experience. The fixing plates 18 are evenly distributed on the right side of the mounting plate 12. The protrusions 21 are embedded in the surface of the fixing plate 18 through the slot 19 and slide on the surface of the fixing plate 18, ensuring uniform force and stability of the filter element during installation. The structure not only provides a reliable fixing effect but also allows for a certain degree of adjustment to adapt to different installation needs.

[0028] Working principle: First, place the mounting plate 12 in the desired position and secure it firmly using the mounting groove 13. Then, pinch the cover 20 and push it to the left, causing the cover 20 to slide the protrusion 21 from the right side of the fixing plate 18 to the left. When the protrusion 21 slides into the slot 19, it firmly secures the cover 20 to the surface of the fixing plate 18. Next, grasp the filter body 1 and push the mounting block 2 to the upper limit groove 16, allowing it to slide into the limiting plate 15. Once the mounting block 2 is fully inside the limiting plate 15, the soft pad 11 secures the mounting plate 12 to the limiting plate 15, and the retaining pad 17 also secures the mounting block 2. Inside the limiting plate 15, a secondary fixing effect is achieved. Then, the protective net 4 is pinched and placed on the surface of the filter element body 1, and the protective net 4 is slid into the interior of the mounting block 2 through the fixing groove 3. Then, the rotating plate 7 is aligned with the rotating groove 6. At this time, the cover plate 8 is rotated by the pinching pad 10, so that the cover plate 8 drives the rotating plate 7 to rotate, and the rotating plate 7 rotates into the interior of the fixing block 5 through the rotating groove 6. When the rotating plate 7 is completely rotated into the interior of the fixing block 5 through the rotating groove 6, and the left side of the cover plate 8 contacts the right side of the protective net 4, the protective net 4 is firmly stuck on the surface of the filter element body 1. During use, the liquid falls into the interior of the filter element body 1 through the guide groove 14 for filtration, and the protective net 4 and the filter screen 9 can protect the filter element body 1.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
