[0002] The filter element of the existing water purifier is generally provided with an inlet channel and an outlet channel. In order to prevent the inside of the filter element from being polluted, a sealing structure is generally provided at the ports of the inlet channel and the outlet channel to seal the inlet channel and the outlet channel and prevent external pollutants from entering. However, the traditional sealing structure is usually a sheet material, which has no good guiding cooperation with the inner wall of the inlet / outlet channel, so that the sealing structure is prone to tilt and displacement. As a result, when the filter element is not installed, the inlet / outlet is likely to be in an unsealed state, causing the inside of the filter element to be polluted by air.

[0033] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0034] As Figure 1 , Figure 2 , Figure 5 , Figure 6 shown, a filter element includes a main body 200, a filtering component 100, and a self-sealing component 300. Among them, the filtering component 100 is arranged inside the main body 200 for filtering water. An inlet channel 21 and an outlet channel 22 are formed inside the main body 200. First flow ports 211 and second flow ports 221 are respectively formed on the side walls of the inlet channel 21 and the outlet channel 22. Self-sealing components 300 are slidably arranged inside the inlet channel 21 and the outlet channel 22. The self-sealing components 300 are used to seal the inlet channel 21 and the outlet channel 22 of the filter element when the filter element is not in use to prevent external pollutants from entering the inside of the filter element. Side ports 3211 and interfaces 3221 are formed on the self-sealing components 300. The side ports 3211 and the interfaces 3221 communicate with each other. Among them, the interfaces 3221 are used to connect to external pipelines, and the side ports 3211 are used to selectively communicate with the first flow ports 211 and the second flow ports 221 during the sliding process of the self-sealing components 300.

[0035] When the filter element is not in use, the side port 3211 is disconnected from the first flow port 211 and the second flow port 221. The self-sealing assembly 300 seals the inside of the filter element, preventing external contaminants from entering the inside of the filter element, thereby protecting the inside of the filter element. When in use, the external pipeline is connected to the interface 3221 of the self-sealing assembly 300. The self-sealing assembly 300 slides so that the side port 3211 is connected to the first flow port 211 and the second flow port 221. Water flows into the filter assembly 100 through the side port 3211 and the first flow port 211. The filtered water flows into the side port 3211 of the self-sealing assembly 300 inside the outlet channel 22 through the second flow port 221 of the outlet channel 22, and then flows out from the interface 3221 of the self-sealing assembly 300 inside the outlet channel 22. During the above process, the self-sealing assembly 300 slides along the inner walls of the inlet channel 21 and the outlet channel 22. The sliding process is restricted by the inner walls of the inlet channel 21 and the outlet channel 22, which can prevent the situation of tilting and jamming during the sliding process.

[0036] The technical details of each component will be introduced one by one below.

[0037] In some embodiments, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the above self-sealing assembly 300 includes a sliding member 32 and an elastic member 31. The side port 3211 and the interface 3221 are formed on the sliding member 32. One end of the elastic member 31 is connected to the inner wall of the inlet channel 21 or the outlet channel 22, and the other end is connected to the sliding member 32. The sliding member 32 can slide along the inlet channel 21 or the outlet channel 22. When the sliding member 32 slides to the first position, the side port 3211 on the sliding member 32 is connected to the first flow port 211 or the second flow port 221. At this time, external water can smoothly flow into the inside of the filter element for filtration and then flow out. When the sliding member 32 slides to the second position, the side port 3211 on the sliding member 32 is disconnected from the first flow port 211 or the second flow port 221. At this time, the self-sealing assembly 300 seals the inside of the filter element, and external contaminants cannot enter the inside of the filter element, thereby playing a role in protecting the inside of the filter element. And the sliding member 32 slides along the inner wall of the inlet channel 21 or the outlet channel 22 under the action of the elastic member 31. Due to the restriction of the inner wall of the inlet channel 21 or the outlet channel 22, and the relatively long radial fitting distance between the sliding member 32 and the inner wall of the inlet channel 21 or the outlet channel 22, the sliding member 32 is not prone to tilting and jamming during the sliding process.

[0038] In some embodiments, such as Figure 6 , Figure 7As shown, a ring groove 01 is provided on the contact surface between the sliding member 32 and the elastic member 31, and one end of the elastic member 31 is fitted inside the ring groove 01. In this way, one end of the elastic member 31 close to the sliding member 32 can be restricted inside the ring groove 01, thereby preventing the elastic member 31 from shifting during the abutment against the sliding member 32. As a result, the force on the sliding member 32 will be more uniform, further reducing the occurrence of tilting and jamming of the sliding member 32 during sliding.

[0039] It can be understood that the elastic member 31 and the sliding member 32 can also be in a fixed connection state. Fixing one end of the elastic member 31 on the sliding member 32 can also ensure that the sliding member 32 is uniformly stressed during sliding.

[0040] In some embodiments, such as Figure 6 , Figure 7 As shown, a limiting rib 02 is further provided on the sliding member 32, and a limiting groove 23 is provided on the side wall of the corresponding water inlet channel 21 or water outlet channel 22. The limiting rib 02 is arranged inside the limiting groove 23 and can slide along the limiting groove 23. In this way, after the limiting rib 02 and the limiting groove 23 are in sliding fit, it can prevent the sliding member 32 from rotating and shifting during sliding. If the sliding member 32 rotates and shifts, when the sliding member 32 is in the first position, the side port 3211 cannot be accurately aligned and communicated with the first flow port 211 or the second flow port 221. Therefore, through the above method, it can be effectively ensured that when the sliding member 32 is in the first position, the side port 3211 of the sliding member 32 can be aligned and communicated with the first flow port 211 or the second flow port 221. In addition, the limiting rib 02 can further limit the sliding direction of the sliding member 32, further reducing the probability of tilting and jamming of the sliding member 32 during sliding.

[0041] In some embodiments, such as Figure 6 , Figure 7 As shown, the self-sealing assembly 300 further includes a first sealing ring 34, and the first sealing ring 34 is arranged around the inner wall of the interface 3221. In this way, it can ensure the sealing performance between the external pipeline and the inner wall of the interface 3221 after the external pipeline is inserted into the interface 3221, thereby avoiding water leakage.

[0042] In some embodiments, such as Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7As shown, the above self-sealing component 300 further includes a seal 33. The seal 33 is used to abut against the sliding member 32. Seals 33 are provided at the open ends of both the water inlet passage 21 and the water outlet passage 22. A through hole 333 for an external pipeline to enter is formed in the middle of the seal 33, and the diameter of the through hole 333 is larger than the diameter of the interface 3221. When the sliding member 32 is in the second position, the end of the sliding member 32 where the interface 3221 is located can abut and fit against the seal 33, which can prevent the sliding member 32 from disengaging from the inside of the water inlet passage 21 or the water outlet passage 22.

[0043] In some embodiments, as Figure 6 , Figure 7 shown, the above self-sealing component 300 further includes a second sealing ring 35. The second sealing ring 35 is arranged between the fitting surfaces of the sliding member 32 and the seal 33. Such a design can make a sealing structure formed after the sliding member 32 abuts and fits tightly against the seal 33, which can prevent the water inside the filter element from flowing out through the gap between the sliding member 32 and the inner wall of the water inlet passage 21 or the water outlet passage 22. In addition, the seal 33 may be impacted during the process of the sliding member 32 sliding to the second position. The second sealing ring 35 is usually made of rubber or silica gel and can play a good buffering role.

[0044] In some embodiments, as Figure 5 , Figure 6 , Figure 7 shown, the above sliding member 32 includes a side-sliding portion 321 and a tapered portion 322. The side-sliding portion 321 and the tapered portion 322 are connected as a whole. A side port 3211 is formed on the side-sliding portion 321, and an interface 3221 is formed on the tapered portion 322. Correspondingly, in the direction from the seal 33 to the sliding member 32, the inner diameter of the through hole 333 gradually increases to form a tapered surface 332 that matches and fits the tapered portion 322. When the sliding member 32 is in the second position, under the action of the elastic member 31, the tapered portion 322 and the tapered surface 332 abut and fit tightly. Through such a design, while it can play a role in abutting against the sliding member 32, it can increase the area of the fitting surface between the sliding member 32 and the seal 33. Thus, more second sealing rings 35 can be arranged between the sliding member 32 and the seal 33, and further the sealing performance between the fitting surfaces of the sliding member 32 and the seal 33 can be improved.

[0045] In some embodiments, as Figure 7As shown, the above-mentioned seal 33 further includes a flange 331. The flange 331 is provided at the edge of the seal 33, and the flange 331 abuts against the open edge of the water inlet passage 21 or the water outlet passage 22. In this way, it can prevent the seal 33 from being overly embedded inside the water inlet passage 21 or the water outlet passage 22, that is, the position of the seal 33 can be limited. Furthermore, the second position of the sliding member 32 can be limited to ensure that the self-sealing assembly 300 can well seal the interior of the filter element.

[0046] This application also provides a water purifier, which includes the above-mentioned filter element.
