[0029] With reference to the accompanying drawings, the technical solutions in the embodiments of the utility model will be described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the utility model.

[0030] In the description of the utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner" and the like indicate the orientation or positional relationship, only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated components or elements must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation of the utility model.

[0032] The filtering process is as follows: the sealing screw 1 is usually installed at the water outlet of the household water supply pipeline, and the water flows into the connecting pipe 2 through the sealing screw 1. The water flow first contacts the filter screen 4 fixed near the inner cavity of the sealing screw 1 end. The filter screen 4 specially blocks the large-particle impurities such as silt and rust in tap water, effectively preventing them from entering the connecting pipe 2. The water flow preliminarily purified by the filter screen 4 directly enters the PP cotton filter core 7 in the filter core installation mechanism 6 under the guidance of the end cover 5, and flows and filters along the outer layer to the inner layer of the PP cotton filter core 7. The partition plate 11 is used to block the water flow, so as to ensure that the water not fully filtered by the PP cotton filter core 7 will not directly flow into the reverse osmosis membrane filter core 8. The PP cotton filter core 7 can further filter out the fine silt, suspended matter and other small-particle impurities in the water, and also has a certain interception effect on part of the bacteria and other microorganisms. After the water flow passes through the PP cotton filter core 7, it enters the reverse osmosis membrane filter core 8. The reverse osmosis membrane filter core 8 uses the reverse osmosis principle to deeply purify the water flow, and can effectively remove the bacteria, microorganisms, residual chlorine and other chemical substances, heavy metal ions and other small pollutants in the water. The clean water filtered by the reverse osmosis membrane filter core 8 flows into the main body 3, and the water-using device is connected to the main body 3. The purified water flows to each water-using place through the main body 3, so that the filter screen 4, the PP cotton filter core 7 and the reverse osmosis membrane filter core 8 work together to comprehensively remove various impurities such as silt, rust, bacteria, microorganisms, residual chlorine and heavy metal ions in the water, and provide clean water for the family.

[0033] The replacement process of the PP cotton filter element 7 or the reverse osmosis membrane filter element 8: when the PP cotton filter element 7 or the reverse osmosis membrane filter element 8 needs to be replaced, the user first manually rotates the relevant part on the main body 3 to separate the main body 3 from the communication pipe 2, then pulls the main body 3 to move the filter element mounting mechanism 6, the PP cotton filter element 7 and the reverse osmosis membrane filter element 8 out of the communication pipe 2, then rotates the filter element mounting mechanism 6, since it is screwed with the main body 3, rotating it can make it separate from the main body 3, then the user operates the limiting assembly 9 which limits the PP cotton filter element 7 or the reverse osmosis membrane filter element 8, the limiting assembly 9 is originally in the clamped state with the clamping assembly 10, by pulling the limiting assembly 9, it will push the clamping assembly 10 to move, so that the internal potential energy of the clamping assembly 10 increases, until the two clamping parts are separated, then the elastic potential energy of the clamping assembly 10 is released, at this time, the limiting assembly 9 and the corresponding clamping assembly 10 are operated to separate, the multiple limiting assemblies 9 no longer limit the movement of the PP cotton filter element 7 or the reverse osmosis membrane filter element 8, the user can remove the old PP cotton filter element 7 or the reverse osmosis membrane filter element 8, replace it with a new one, after the replacement is completed, the limiting assembly 9 is pushed again to make its two ends close to the clamping assembly 10, the limiting assembly 9 will push the clamping assembly 10 to move again and accumulate potential energy, when the limiting assembly 9 and the clamping assembly 10 are clamped again, the clamping assembly 10 releases the elastic potential energy, locks the limiting assembly 9, limits its movement, so as to fix the new PP cotton filter element 7 or the reverse osmosis membrane filter element 8, it is worth noting that the elastic potential energy of the clamping assembly 10 is much greater than the force of the water flow on the PP cotton filter element 7 or the reverse osmosis membrane filter element 8, which ensures the stability of the filter element under normal water flow impact, finally, the filter element mounting mechanism 6 is rotated and installed back to the main body 3, and the main body 3 is rotated and installed back to the communication pipe 2, the whole filter element replacement process is completed smoothly, so as to realize the replacement of the PP cotton filter element 7 or the reverse osmosis membrane filter element 8, and make the filtering system run stably again.

[0034] In one embodiment, for the above-mentioned main body 3, the main body 3 comprises a threaded knob 301, the threaded knob 301 is screwed on the communication pipe 2, one end of the threaded knob 301 is rotatably connected with a threaded joint 302, one end of the threaded joint 302 is fixedly installed with a threaded mounting ring 305.

[0035] The filter element mounting mechanism 6 comprises two mounting plates 601 and a connecting ring 604, one of the two mounting plates 601 is fixedly installed with a threaded mounting head 602, the threaded mounting head 602 is screwed on the threaded mounting ring 305.

[0036] Two said mounting plates 601 are fixedly installed with a plurality of connecting rods 603 at one end close to each other, the close end of the plurality of connecting rods 603 is fixedly installed on the connecting ring 604, and the PP cotton filter core 7 and the reverse osmosis membrane filter core 8 are located between the connecting ring 604 and the two mounting plates 601 respectively.

[0037] When it is necessary to replace the PP cotton filter core 7 or the reverse osmosis membrane filter core 8, the user first rotates the threaded head 301, since the threaded head 301 is threadedly connected with the communicating pipe 2, rotation causes it to separate from the communicating pipe 2, and then the threaded head 301 or the threaded joint 302 can drive the filter core mounting mechanism 6 to move out of the communicating pipe 2 as a whole, subsequently, the connecting ring 604 is rotated, since the connecting ring 604 is fixedly connected with the threaded mounting head 602 through the plurality of connecting rods 603 and the mounting plates 601, and since the threaded mounting head 602 is threadedly connected with the main threaded mounting ring 305, the threaded mounting head 602 and the main threaded mounting ring 305 are separated during rotation, at this time, the entire filter core mounting mechanism 6 can be exposed, which is convenient for operating the limiting assembly 9 inside, since the PP cotton filter core 7 and the reverse osmosis membrane filter core 8 are located between the connecting ring 604 and the two mounting plates 601 respectively, it is convenient for operating the PP cotton filter core 7 or the reverse osmosis membrane filter core 8, in addition, the two mounting plates 601 are fixedly installed with the connecting ring 604 through the plurality of connecting rods 603, thereby providing a stable bearing structure for the PP cotton filter core 7 and the reverse osmosis membrane filter core 8.

[0038] In one embodiment, for the above-mentioned limiting assembly 9, the limiting assembly 9 comprises a limiting rod 901, both ends of the limiting rod 901 are fixedly installed with clamping blocks 902, a clamping groove 903 is formed on one side of the clamping block 902, and the one side of the clamping block 902 located on the clamping groove 903 is an inverted bevel.

[0039] Both the two mounting plates 601 and the connecting ring 604 are internally provided with a plurality of mounting holes 605, and the clamping assembly 10 comprises a spring 1001, and the spring 1001 is located in the inner cavity of the mounting hole 605.

[0040] One end of the spring 1001 is fixedly installed on the inner wall of the mounting hole 605, and the other end is fixedly installed with a spherical body 1002, and the spherical body 1002 can be clamped in the clamping groove 903.

[0041] Based on the description of the above working principle, when the threaded mounting head 602 is separated from the main threaded mounting ring 305, the user then pulls the limiting rod 901. Due to the reverse bevel design of the clamping block 902, during the pulling process, the clamping block 902 contacts the ball 1002 and pushes the ball 1002 to move inside the mounting hole 605, compressing the spring 1001 and accumulating the elastic potential energy of the spring 1001. With the continuous pulling of the limiting rod 901, the ball 1002 finally separates from the clamping groove 903. At this time, the spring 1001 reaches the maximum elastic potential energy, and after the ball 1002 separates from the clamping groove 903, the PP cotton filter element 7 and the reverse osmosis membrane filter element 8 are no longer restricted by the limiting rod 901. The user can then remove the old PP cotton filter element 7 or reverse osmosis membrane filter element 8 from between the connecting ring 604 and the two mounting plates 601. Then, place the new PP cotton filter element 7 or reverse osmosis membrane filter element 8 in the corresponding position, and then push the limiting rod 901 so that the clamping groove 903 of the clamping block 902 is close to the ball 1002. With the pushing of the limiting rod 901, the reverse bevel of the clamping block 902 again contacts the ball 1002, pushing the ball 1002 to move inside the mounting hole 605 and compressing the spring 1001. When the clamping groove 903 moves to the corresponding position of the ball 1002, the spring 1001 releases the elastic potential energy, pushing the ball 1002 to be clamped into the clamping groove 903, and the limiting rod 901 is locked again. The fixing of the new PP cotton filter element 7 or reverse osmosis membrane filter element 8 is completed. Finally, the connecting ring 604 is rotated again, so that the threaded mounting head 602 is rotated and mounted back onto the threaded mounting ring 305, and then the main body 3 is mounted back onto the communication pipe 2. Thus, the replacement work of the PP cotton filter element 7 or reverse osmosis membrane filter element 8 is completed, so that the PP cotton filter element 7 or reverse osmosis membrane filter element 8 can be replaced, and the filtering system can be operated stably again.
