[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0032] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0033] like Figures 1-10 As shown, this invention provides a nano-microbial water purifier, comprising: a material cylinder 1 and an aeration device; a counterweight 3 is provided at the top of the material cylinder 1 to keep the material cylinder 1 below the liquid surface; a packing zone 11 is provided inside the material cylinder 1, and the packing zone 11 is filled with packing material, which is a biological agent. The aeration device extends into the material cylinder 1, and a first distance is reserved between the bottom of the material cylinder 1 and the riverbed, so that liquid can enter the material cylinder 1 from the bottom. Several first holes are provided on the side wall of the material cylinder 1.

[0034] The inner wall of the barrel 1 is provided with a partition 4, which divides the barrel 1 into upper and lower parts, the upper part being a filler area 11 and the lower part being a liquid area 12. The barrel 1 is provided with a first hole, so that liquid can enter the filler area 11 and the liquid area 12, thereby achieving the effect of biological filtration in the filler area. The first hole can also physically filter the liquid entering the liquid area 12, reducing impurities entering the liquid area 12. The counterweight 3 is located at the top of the filler area 11, and the aeration device extends into the liquid area 12. The partition 4 is provided with a second hole and a filler adder 5, which communicates with the filler area 11 through the second hole. The filler adder 5 communicates with a filler supply, so that the filler area can be replenished with filler.

[0035] The first pipe 61, the second pipe 62 and the pipe connector 63 are also included. The second pipe 62 and the pipe connector 63 are located in the counterweight 3 and can be used as counterweights, thereby reducing the number of counterweights used in the counterweight 3. One end of the first pipe 61 communicates with one end of the pipe connector 63, the other end penetrates the filler area 11 and the partition 4 and extends into the liquid area 12. The other end of the pipe connector 63 communicates with one end of the second pipe 62, and the other end of the second pipe 62 extends horizontally to the outside of the counterweight 3. The aeration device communicates with the first pipe 61, as shown in Figure 1 The center axis of the second pipe 62 is flush with the liquid level, and the bottom of the first pipe 61 is separated from the river bottom by a second distance, as shown in Figure 3 The second distance is greater than the first distance, so that the liquid can be smoothly sucked into the first pipe 61.

[0036] The vertical rod 71 is also included, which is fixed at the bottom to the river bottom and extends above the liquid level at the top. The vertical rod 71 and the counterweight 3 are connected by a connecting rod 72, and the extension line of the connecting rod 72 is normal to the center axis of the second pipe 62, as shown in Figure 2 This allows the purifier to rotate around the vertical rod as the rotation axis.

[0037] The working principle and beneficial effects of the technical solution are as follows: through the design of the above structure, the aeration device can introduce oxygen in the air into the water, increasing the dissolved oxygen content in the water body. Because the aeration device extends into the barrel 1 and communicates with the first pipe 61, the gas will be sprayed out from the second pipe 62 after passing through the pipe connector 63 from the first pipe 61. During the gas flow process, liquid is sucked into the bottom of the barrel 1 and flows into the first pipe 61. The liquid in the first pipe 61 will be pumped to the second pipe 62 under the action of the pressure difference and sprayed out from the second pipe 62. Because the second pipe 62 needs to be adjusted to the center axis of the liquid surface by the counterweight 3, the sprayed water flow will impact the liquid surface, thereby further aerating the water body. At the same time, the sprayed water flow will drive the purifier to rotate along the central stand 71 of the river, thereby changing the aeration position. In addition to the basic aeration function, the purifier also has a biological filtration function. By filling the filler area with fillers, the river is biologically filtered. The aeration position is changed by the rotating water flow, the water flow in different temperature layers above and below the water is disturbed, and the exchange of nutrients and oxygen in different water temperature layers is realized. Not only does it promote the decomposition of organic matter and the growth of microorganisms in the water body, but it also improves the self-purification ability of the water body.

[0038] Further, the aeration device is composed of a gas supply source 21, a third pipe 22 and an aeration nozzle 23. The gas supply source 21 is arranged on the top of the counterweight 3 and serves as a counterweight. The aeration nozzle 23 is arranged on the outer wall of the first pipe 61 and communicates with the first pipe 61. The aeration nozzle 23 communicates with the gas supply source 21 through the third pipe 22.

[0039] Further, the outer wall of the first pipe 61 is provided with a flow guide plate 8, and the side wall of the first pipe 61 is provided with a third hole 611. The flow guide plate 8 and the third hole 611 are both located in the liquid area 12. The center axis of the third hole 611 passes through the surface of the flow guide plate 8. After the liquid is sucked into the first pipe 61, part of the liquid will be sprayed out from the third hole 611. The sprayed water flow directly impacts the surface of the flow guide plate 8. Under the guidance of the flow guide plate 8, the direction of the water flow in the liquid area 12 can be consistent.

[0040] In the foregoing embodiments, we mentioned that fillers can be supplemented into the filler area 11 by the filler adder 5. The fillers are usually biological agents. However, according to different use scenarios, the purifier may need to be equipped with fillers other than biological agents. At this time, a single filler area 11 cannot meet the diversified needs of fillers. Therefore, we further provide an implementation to expand the filler area 11, so that the purifier can simultaneously carry multiple styles and types of fillers.

[0041] In the embodiment, the partition 4 is provided with a fourth hole, and a plurality of detachable filler boxes 9 are arranged in the fourth hole;

[0042] When only one kind of filler is needed, a detachable cover plate is arranged in the fourth hole, and the inner wall of the fourth hole is provided with internal threads, and the outer wall of the cover plate is provided with external threads, and the fourth hole is threadedly connected with the cover plate;

[0043] When a plurality of fillers are needed, the cover plate is detached from the fourth hole, and then the filler box 9 is connected with the fourth hole. If a plurality of filler boxes 9 are arranged, the filler boxes 9 are connected with each other in an up-down manner, and then the uppermost filler box 9 is connected with the fourth hole, as shown in Figure 4 .

[0044] The filler box 9 is arranged above the deflector 8, so that the water flow separated by the deflector 8 can flow upwards to the filler area 11 by the filler box 9.

[0045] Further, the filler box 9 is composed of an outer box body 91, an inner box body 92, a support plate 93 and a cover 94, the inner box body 92 is arranged in the outer box body 91, the support plate 93 is arranged in the inner box body 92, the cover 94 is detachably connected with the outer box body 91, and the top of the lower outer box body 91 and the bottom of the upper outer box body 91 are detachably connected between adjacent two filler boxes 9, as shown in Figure 10 .

[0046] Further, the outer box body 91 is a cylindrical structure with an open top, the outer bottom of the outer box body 91 is provided with an annular clamping groove 911, and at least three clamping pieces are arranged at the open top of the outer box body 91, an installation space is formed between adjacent two clamping pieces, the clamping piece is composed of a C-shaped clamping ring 912 (with a C-shaped cross section) and a clamping plate 913, one end (the lower end of the C shape) of the C-shaped clamping ring 912 is connected with the opening of the outer box body 91, and the other end (the upper end of the C shape) is connected with the clamping plate 913, as shown in Figure 5 , the clamping plate 913 is an arc-shaped plate, the curvature of the clamping plate 913 is adapted to the inner groove surface of the annular clamping groove 911, and the connection between the clamping plate 913 and the C-shaped clamping ring 912 has elasticity, and the clamping plate 913 always has a restoring tendency when the clamping plate 913 is clamped with the fourth hole or the annular clamping groove 911 at the bottom of the outer box body 91 of another filler box 9;

[0047] When the filler box 9 is connected with the fourth hole, the clamping plate 913 of the outer box body 91 penetrates through the fourth hole and is clamped with the fourth hole, as shown in Figure 4 , at this time, the outer surface of the clamping plate 913 abuts against the inner wall of the fourth hole;

[0048] When the two adjacent filler boxes 9 are connected, the clamping plate 913 of the lower (outer box body 91) is clamped with the annular clamping groove 911 of the upper (outer box body 91), as shown in the figure, at this time the outer surface of the clamping plate 913 abuts with the inner surface of the annular clamping groove 911 (close to the outer side); Figure 10

[0049] The bottom of the outer box body 91 is provided with a fifth hole, as shown in the figure, the water flow guided by the flow guide plate 8 can enter the outer box body 91 through the fifth hole. Figure 6

[0050] Further, the inner box body 92 is a tubular structure, the outer side wall of the inner box body 92 is provided with a positioning ring 921 in the circumferential direction, the outer wall of the positioning ring 921 abuts with the inner wall of the outer box body 91, the positioning ring 921 is used for limiting the inner box body 92 in the horizontal direction, the bottom of the inner box body 92 is provided with at least three supporting legs 922, the supporting legs 922 extend away from the inner box body 92 from the bottom of the inner box body 92, the inner box body 92 is connected with the inner bottom surface of the outer box body 91 through the supporting legs 922, as shown in the figure, generally the bottom of the inner box body 92 is open, provided with a mounting ring 923 extending into the inner box body 92, the supporting legs 922 are arranged on the inner wall of the mounting ring 923, by arranging the supporting legs 922, the third distance between the bottom of the inner box body 92 (or the bottom surface of the mounting ring 923) and the inner bottom surface of the outer box body 91 is formed, so that the water storage space is formed between the bottom of the inner box body 92 and the inner bottom surface of the outer box body 91, the water flow guided by the flow guide plate 8 can enter the water storage space from the fifth hole, so as to slow down the flow rate of the water flow entering the inner box body 92. Figure 5

[0051] Generally, the inner wall of the inner box body 92 is provided with a lap joint ring 924, the lap joint ring 924 is located above the supporting leg 922 (and the mounting ring 923), the supporting plate 93 is arranged on the lap joint ring 924, generally the connection part of the lap joint ring 924 and the inner box body 92 is higher than the inner opening of the lap joint ring 924, so that the lap joint ring 924 is in a downward inclined state, as shown in the figure. Figure 5

[0052] The outer side wall of the inner box body 92 and the inner side wall of the outer box body 91 leave a fourth distance, at least three sixth holes 925 are arranged on the side wall of the inner box body 92, the sixth holes 925 are located above the positioning ring 921, the inner box body 92 communicates with the outer box body 91 through the sixth holes 925.

[0053] Further, the top opening of the inner box body 92 is located below the top opening of the outer box body 91. When the water flow flows from bottom to top, the water flow can flow into the outer box body 91 from the top of the inner box body 92 and the sixth hole 925. ​​​​

[0054] Furthermore, the shape of the support plate 93 is adapted to the shape of the overlapping ring 924. The outer wall of the support plate 93 abuts against the inner wall of the inner box 92, the bottom surface of the support plate 93 abuts against the top surface of the overlapping ring 924, and the edge of the support plate 93 is located above the center of the support plate 93. Figure 5 As shown, this design results in a concave shape for the support plate 93. The support plate 93 also has at least three seventh holes 931 located within the openings of the overlapping ring 924. These seventh holes 931 allow water to flow from the water storage space into the inner tank 92. The concave shape of the support plate 93 allows it to rest directly on the inner bottom surface of the outer tank 91 when the packing material inside the inner tank 92 becomes too heavy, causing the support legs 922 to bend and deform, and thus unable to provide effective support for the inner tank 92.

[0055] Furthermore, the side wall of the cover 94 is provided with at least three C-shaped locking platforms 941 that adapt to the inner wall of the C-shaped locking ring 912. Adjacent C-shaped locking platforms 941 form a misalignment space. When installing the cover 94, the C-shaped locking platforms 941 are first placed within the installation space, at which point the locking component is located within the misalignment space. Figure 5 and Figure 6 As shown. Then, rotate the cover 94 so that the C-shaped locking platform 941 rotates into the C-shaped locking ring 912, thereby completing the connection between the cover 94 and the outer casing 91, as shown. Figures 7-8 As shown. After the C-shaped locking plate 941 is inserted into the C-shaped locking ring 912, the connection between the locking plate 913 and the C-shaped locking ring 912 abuts against the top surface of the cover 94, thereby limiting the bending angle and deformation height of the locking plate 913, and thus increasing the locking force between the outer casing 91 and the annular locking groove 911 (or the fourth hole). The cover 94 is provided with at least three eighth holes 942 for water flow inside the outer casing 91.

[0056] Through the above structural design, Figure 4 and Figure 10 For example, water flows through the guide plate 8 and enters the lower packing box 9, then flows into the upper packing box 9, and finally enters the packing area 11. This allows the purifier to be equipped with multiple different packing materials for treating river pollution. Furthermore, the snap-fit ​​connection method using the clamping plate 913 makes the assembly and disassembly of the packing box 9 more convenient. The upward flow of water continuously provides upward force to the packing box 9, reducing the risk of it falling due to excessive weight. Moreover, the packing box 9 can be made entirely of plastic, significantly reducing its production cost.
