[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1 to 3This utility model provides a technical solution: a refrigerator filter element with a simple structure and good filtration effect, including an activated carbon rod 1, an upper outer shell 2, and a lower outer shell 3. The bottom of the upper outer shell 2 and the top of the lower outer shell 3 are fixedly connected. The top and bottom of the activated carbon rod 1 are respectively fixed with a carbon rod upper cover 4 and a carbon rod lower cover 5. The lower outer shell 3 has a water-absorbing cavity 15 for inserting and fixing the activated carbon rod 1. The upper outer shell 2 has a water inlet 16 on the top left side and a water outlet 17 on the top right side. An installation assembly is installed on the inner side of the lower outer shell 3, and a protective cover 6 is detachably connected to the outer side of the upper outer shell 2. Through the coordinated use of activated carbon rod 1, upper outer shell 2, lower outer shell 3, wading cavity 15, inlet 16, and outlet 17, it can efficiently remove odors, filter bacteria, and is easy to replace. The tight and ingenious linkage design between the components, coupled with simple operation, achieves both efficient filtration of incoming water and convenient and quick filter replacement, enhancing user convenience and comfort. Furthermore, the compact overall structure, through the cooperation of various components, improves the stability and reliability of the filter element, ensuring long-term stable and effective filtration, and providing users with a better user experience.
[0024] It should be noted that a second sealing groove is provided on the outer side of the carbon rod cover 4, and a second sealing ring 13 is provided on the inner side of the second sealing groove. A third sealing groove is provided on the top of the upper outer shell 2 on the outer side of the water inlet 16 and the water outlet 17, and a third sealing ring 14 is provided on the inner side of the third sealing groove. The sealing of the corresponding connection can be ensured by the second sealing ring 13 and the third sealing ring 14.
[0025] In addition, the activated carbon rod 1 is located on the outside of the cylindrical part at the bottom of the upper shell 2. The upper cover 4 of the carbon rod is fixedly connected to the outside of the upper shell 2, and the lower cover 5 of the carbon rod is fixedly connected to the inside of the water-immersing cavity 15, so that the activated carbon rod 1 can stably work inside the water-immersing cavity 15.
[0026] It should also be noted that the activated carbon rod 1 is a cylindrical ring, and the outer side of the activated carbon rod 1 is wrapped with filter non-woven fabric. The top of the carbon rod cover 4 has a water inlet hole that communicates with the part of the water-immersing cavity 15 located on the outer side of the activated carbon rod 1. The inside of the water inlet hole is connected to the inside of the water inlet 16. The top of the carbon rod cover 4 has a water outlet hole that communicates with the inside of the activated carbon rod 1. The inside of the water outlet hole is connected to the inside of the water outlet 17. This allows the incoming water to be transported to the part of the water-immersing cavity 15 located on the outer side of the activated carbon rod 1 through the water inlet 16 and the water inlet hole. Through the sequential filtration of the filter non-woven fabric and the activated carbon rod 1, the incoming water can be effectively filtered. The filtered water is located inside the activated carbon rod 1 and can be discharged through the water outlet hole and the water outlet 17. After the entire filter element is installed, the water-immersing cavity 15, except for the holes, is fixed or sealed at all other connection points, so that the water inside can only flow through the designated channels.
[0027] In this embodiment, the installation component is a structure used to ensure the refrigerator filter element can be installed properly and to guarantee the sealing of the connection.
[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the installation components include a limiting member 7, a knob 8, a fastener 9, a threaded part 10, an aluminum rod 11, a first sealing ring 12, a second sealing ring 13, and a third sealing ring 14.
[0029] The lower outer shell 3 has a limiting cavity inside for the limiting member 7 to rotate. The knob 8 is fixed to the bottom of the limiting member 7. The bottom of the lower outer shell 3 has a rotating groove that communicates with the inside of the limiting cavity. The top of the limiting member 7 is for the aluminum rod 11 to pass through and be fixed. The threaded part 10 is fixed to the top of the aluminum rod 11. The aluminum rod 11 passes through the interior of the upper outer shell 2 and extends to the top of the upper outer shell 2. The outer side of the aluminum rod 11 is rotatably connected to a fastener 9 that is fixed to the top of the upper outer shell 2.
[0030] It should be noted that the rotating groove is for the knob 8 to rotate. The cross-section of the upper outer shell 2 is T-shaped. The bottom end of the upper outer shell 2 passes through the top of the lower outer shell 3, the carbon rod upper cover 4, and the carbon rod lower cover 5 and extends to the top of the limiting member 7. By rotating the knob 8, the limiting member 7 can be rotated in the limiting cavity.
[0031] In addition, the bottom of the upper outer shell 2 is cylindrical, and a first sealing groove is provided at the bottom of the outer side of the upper outer shell 2. A first sealing ring 12 is provided on the inner side of the first sealing groove and abuts against the inner side of the carbon rod lower cover 5. The sealing of the connection between the upper outer shell 2 and the carbon rod lower cover 5 can be ensured by the first sealing ring 12.
[0032] It should also be noted that the threaded part 10 can be connected to the connector of the refrigerator filter element. When connecting, it is necessary to ensure that the refrigerator's water inlet and outlet pipes correspond to the water inlet 16 and the water outlet 17. By rotating the knob 8, the limiting part 7 rotates in the limiting cavity, thereby causing the aluminum rod 11 to drive the threaded part 10 to rotate, achieving the effect of threaded connection.
[0033] The working principle of the above embodiments is as follows:
[0034] When using this refrigerator filter, the circulating water containing odors and impurities enters the wading cavity 15 through the inlet 16. Guided by the internal structure, the non-woven fabric wrapping the activated carbon rod 1 first adsorbs and filters the tiny impurities in the water. Then, the activated carbon rod 1 performs secondary filtration, which effectively intercepts the trace impurities in the water and causes the water to gather inside the activated carbon rod 1. After filtration, the water flows out from the outlet 17, completing the filtration process.
[0035] Compared with existing technologies, this refrigerator filter element, with its simple structure and excellent filtration effect, utilizes the coordinated operation of activated carbon rod 1, upper outer shell 2, lower outer shell 3, wading cavity 15, water inlet 16, and water outlet 17 to efficiently remove odors, filter bacteria, and facilitate easy replacement. Through the tight and ingenious linkage design between the components and its simple operation, it achieves both efficient filtration of incoming water and convenient and quick filter element replacement, enhancing user convenience and comfort. Furthermore, the compact overall structure, with its coordinated components, improves the stability and reliability of the filter element, ensuring long-term stable and effective filtration, providing users with a better experience. This solves the problems of complex structures, inconvenient replacement, and increased user costs and maintenance difficulties associated with existing refrigerator filters.
