Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-6 As shown, a lightweight household reverse osmosis water purifier includes a main body 100 and a filter cartridge 200. The bottom of the main body 100 is provided with a plug 101, and the plug 101 is provided with a fixing mechanism for fixing the filter cartridge 200. The main body 100 is provided with an outlet 102 and an inlet 103 in the plug 101. A composite filter element 300 is provided at the inlet 103. The fixing mechanism facilitates the installation and removal of the filter cartridge, thereby accelerating the replacement rate of the filter element. By using a composite filter element, the number of parts is reduced, the overall size is reduced, and the weight is reduced, thus achieving a lightweight device.

[0027] In this embodiment, as Figure 6As shown, the composite filter element 300 includes an upper fixing plate 301 and a lower fixing plate 302. The upper fixing plate 301 has a filtered water outlet 303, which is inserted into the water inlet 103. A reverse osmosis filter membrane element 304 is disposed between the upper fixing plate 301 and the lower fixing plate 302. An activated carbon filter element 305 is disposed at the outer end of the reverse osmosis filter membrane element 304, and a pleated PP cotton filter element 306 is disposed at the outer end of the activated carbon filter element 305. The reverse osmosis filter membrane element 304 and the activated carbon filter element 306 are connected by... The 05 and pleated PP cotton filter element 306 are integrated into the same filter element housing in a stacked structure, forming a three-in-one composite filter element. This reduces the number of parts and the overall size of the machine. The pleated structure of the pleated PP cotton filter element 306 increases the filtration area, which can more densely intercept large particles of impurities such as mud, rust, and colloids in the water. It can process a larger volume of water per unit time and significantly improve filtration efficiency. With the increased filtration area, impurities no longer accumulate in local areas on the surface of the filter element, which extends the overall service life of the filter element by 30%-50% and reduces the frequency of replacement.

[0028] In one embodiment, such as Figure 4 and Figure 5 As shown, the fixing mechanism includes a movable frame 401, which is slidably connected to a groove 402 in the insert 101. One end of a spring 403 is fixedly connected to one side of the movable frame 401, and the other end of the spring 403 is fixedly connected to the inner wall of the groove 402. A pressing block 404 is provided on the side of the movable frame 401 away from the spring 403, and the pressing block 404 extends out of the groove 402. Two inclined grooves 405 are provided on the movable frame 401, and sliders 406 are slidably connected in the two inclined grooves 405. Slider 406 is fixedly connected to a locking block 407, and locking block 407 is slidably connected to a guide rail 408. The guide rail 408 is fixed. The filter cartridge 200 is connected to the inner wall of the groove 402. It is provided with a slot 409 that cooperates with the locking block 407. When the pressing block 404 is pressed, the pressing block 404 drives the moving frame 401 to move and compresses the spring 403. Since the slider 406 is slidably connected in the inclined groove 405 and the locking block 407 is slidably connected to the guide rail 408, when the moving frame 401 moves, the slider 406 will drive the locking block 407 to move along the guide rail 408 into the groove 402, inserting the filter cartridge 200 into the insert 101. When the pressing block 404 is released, the locking block 407 will reset under the action of the spring 403 and lock into the slot 409, fixing the filter cartridge 200 and the insert 101.

[0029] In one embodiment, such as Figure 4As shown, the upper end of the filter cartridge 200 is provided with a movable groove 501, in which a movable ring 502 is slidably connected. One end of the movable ring 502 is fixedly connected to a second spring 503, and the other end of the second spring 503 is fixedly connected to the inner wall of the movable groove 501. The end of the movable ring 502 away from the second spring 503 is fixedly connected to a first sealing ring 504. When the filter cartridge 200 is fixed on the insert 101, the second spring 503 will push the movable ring 502 against the insert 101. With the cooperation of the locking block 407, the filter cartridge 200 is fixed more firmly. When the movable ring 502 is against the insert 101, the first sealing ring 504 at the upper end will fit against the surface of the insert 101 to prevent leakage.

[0030] In one embodiment, such as Figure 4 As shown, the outer end of the filtered water outlet 303 is provided with a sealing ring 600, which can tightly fit the filtered water outlet 303 and the water inlet 103, fill the tiny gaps, and prevent the purified water from leaking from the interface.

[0031] In one embodiment, such as Figure 5 As shown, the two inclined grooves 405 are symmetrically distributed on the moving frame 401. The symmetrical distribution can more firmly fix the filter cartridge 200 on the insert 101.

[0032] In one embodiment, such as Figure 3 As shown, the lower end of the filter cartridge 200 is fixedly connected to the support plate 700. The support plate 700 provides support for the composite filter element 300 and prevents the filtered water outlet 303 of the composite filter element 300 from falling out of the inlet 103.

[0033] In one embodiment, such as Figure 6 As shown, the outer end of the folded PP cotton filter element 306 is provided with a fixing net 800. The two ends of the fixing net 800 are fixedly connected to the upper fixing plate 301 and the lower fixing plate 302 respectively. Due to the folded structure of the folded PP cotton filter element 306, it is easy to spread outward. By setting the fixing net 800 to fix the PP cotton filter element 306, the movement of the PP cotton filter element 306 is prevented. The fixing net 800 can also play a protective role for the composite filter element 300.

[0034] The above embodiment discloses a lightweight household reverse osmosis water purifier. Pressing the pressing block 404 moves the moving frame 401, compressing the spring 403. Since the slider 406 is slidably connected in the inclined groove 405, and the locking block 407 is slidably connected to the guide rail 408, when the moving frame 401 moves, the slider 406 drives the locking block 407 to move along the guide rail 408 into the groove 402, inserting the filter cartridge 200 into the insert 101. Releasing the pressing block 404 causes the locking block 407 to reset under the action of the spring 403, locking into the slot 409, thus connecting the filter cartridge 200 and the insert 101. Fixed; By integrating the reverse osmosis filter membrane element 304, activated carbon filter element 305, and pleated PP cotton filter element 306 into the same filter element housing in a stacked structure, a three-in-one composite filter element is formed, reducing the number of parts and shrinking the overall size of the machine. The pleated structure of the pleated PP cotton filter element 306 increases the filtration area, which can more densely intercept large particulate impurities such as silt, rust, and colloids in the water, and process a larger amount of water per unit time, significantly improving filtration efficiency. With the increased filtration area, impurities no longer accumulate in local areas on the filter element surface, extending the overall service life of the filter element by 30%-50% and reducing the frequency of replacement.

[0035] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
