DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 - Figure 3, the utility model provides an embodiment: a reverse osmosis membrane water purifier with convenient removal of the filter element, comprising a body 1, the outer wall of the body 1 is fixedly connected with a first mounting ring 2, the upper surface of the first mounting ring 2 is provided with a second mounting ring 3, the interior of the second mounting ring 3 is slidably connected with a pull rod 4, the outer wall of the pull rod 4 is sleeved with a first spring 5, one end of the first spring 5 is fixedly connected to the interior of the second mounting ring 3, the other end of the first spring 5 is fixedly connected to a connecting seat 6, the interior of the connecting seat 6 is rotatably connected with a movable rod 7, the outer wall of the movable rod 7 is rotatably connected with a slider 8, the outer wall of the slider 8 is slidably connected with an insert block 9, the outer wall of the insert block 9 is slidably connected to the interior of the first mounting ring 2, the interior of the insert block 9 is fixedly connected with a limit rod 10, the interior of the slider 8 is slidably connected to the outer wall of the limit rod 10, the outer wall of the limit rod 10 is sleeved with a second spring 11, the outer wall of the slider 8 is fixedly connected with a block 12, and the interior of the second mounting ring 3 is provided with an observation component; one end of the second spring 11 is fixedly connected to the interior of the insert block 9, and the other end of the second spring 11 is fixedly connected to the outer wall of the slider 8;

[0024] Specifically, pull the pull rod 4 upward so that the connecting seat 6 can slide inside the second mounting ring 3. Then, the movable rod 7 pulls the slider 8 to slide along the outer wall of the limit rod 10. When the block 12 completely slides into the plug block 9, it no longer restricts the first mounting ring 2. At this time, the second mounting ring 3 can be pulled upward to make the plug block 9 slide out of the first mounting ring 2, and the filter element can be easily disassembled. Thereby, damage to the water purifier can be effectively avoided and its service life can be extended. At the same time, it not only improves the convenience of the water purifier, but also extends the service life of the water purifier by reducing the risk of damage during the disassembly process.

[0025] Reference Figure 1 - Figure 2 The observation assembly includes a transparent cover 13, and the outer wall of the transparent cover 13 is fixedly connected to the inside of the second mounting ring 3;

[0026] Specifically, the transparent cover 13 is fixed to the outside of the fixing ring 14 so that the fixing ring 14 can be observed through the transparent cover 13 , thereby achieving an effect of being able to observe the internal situation of the transparent cover 13 in real time.

[0027] Reference Figure 1 and Figure 4The interior of the second mounting ring 3 is fixedly connected with a fixing ring 14, and the outer wall of the fixing ring 14 is fixedly connected with an outer filter 15; the interior of the outer filter 15 is fixedly connected with an inner filter 16, and the interior of the inner filter 16 is fixedly connected with a fixing frame 17; the interior of the fixing frame 17 is rotatably connected with a rotating shaft 18, and the outer wall of the rotating shaft 18 penetrates the interior of the inner filter 16 and the outer filter 15 respectively; the outer wall of the rotating shaft 18 is fixedly connected with a driving blade 19, and the outer wall of the rotating shaft 18 is fixedly connected with a stirring blade 20; the outer wall of the rotating shaft 18 is fixedly connected with a scraper 21, and the outer wall of the scraper 21 is slidably connected to the outer wall of the outer filter 15;

[0028] Specifically, first, the rotation of the stirring blade 20 makes the water flow inside the outer filter 15 and the inner filter 16 fully stirred. This agitation not only increases the contact area between the water flow and the filter, but also increases the speed and power of the water flow, which helps to better filter and purify the water quality and significantly improves the filtering effect. Secondly, the rotation of the scraper 21 can clean the impurities at the bottom of the outer wall of the outer filter 15. The scraper 21 can easily scrape off the impurities on the outer filter 15 to prevent these impurities from clogging the filter and ensure smooth water flow. This not only extends the service life of the filter element, but also avoids the decrease in filtering effect due to clogging of impurities, thereby further ensuring the quality of water.

[0029] Working principle: when it is necessary to disassemble the filter element inside the water purifier separately, by pulling the pull rod 4 upwards, the pull rod 4 can drive the connecting seat 6 to slide upwards, and then the movable rod 7 pulls the slider 8, so that the slider 8 slides on the outer wall of the limit rod 10 and the second spring 11 can be compressed at the same time, until the block 12 completely slides into the plug block 9 and no longer restricts the first mounting ring 2, and then the second mounting ring 3 is pulled upwards, so that the plug block 9 can slide out of the first mounting ring 2, so as to achieve the effect of disassembling and cleaning the filter element separately, which improves the convenience of the water purifier and prolongs the service life of the water purifier. When the water purifier needs to be stirred and filtered, the water flow impacts the driving blade 19, thereby driving the driving blade 19 to rotate around the rotating shaft 18, so that the rotating shaft 18 can drive the stirring blade 20 and the scraper 21 to rotate, wherein the stirring blade 20 can fully stir the water flow inside the outer filter 15 and the inner filter 16, and thus better contact and filter with the outer filter 15 and the inner filter 16, while the scraper 21 can scrape off impurities at the bottom of the outer wall of the outer filter 15 to prevent clogging of the outer filter 15, thereby achieving the effect of fully filtering the internal water flow, improving the practicability of the water purifier, and ensuring the quality of water.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
