The structure of the second cartridge body 30 will be described below with emphasis on the description.

As shown in fig. 3, in a specific structure, the second filter element body 30 includes a second casing 331, the second casing 331 is provided with a second water inlet 31 at the bottom, and the second casing 331 is provided with a second water outlet 32 at the top. Wherein the second water inlet 31 is used for supplying water treated by the first filter element body 20 to enter from the bottom, and the second water outlet 32 is used for supplying water treated by the second filter element body 30 to flow out from the top.

A water inlet filter screen 341 is arranged at one end of the second casing 331 close to the second water inlet 31, and a water outlet filter screen 351 is arranged at one end of the second casing 331 close to the second water outlet 32. The water inlet filter screen 341 and the water outlet filter screen 351 can filter water entering and flowing out of the second filter element body 30 on one hand, and can block the activated carbon particles 371 mentioned later on the other hand, so that the activated carbon particles 371 are ensured not to flow out of the second filter element body 30. That is, the diameters of the inlet filter screen 341 and the outlet filter screen 351 are smaller than the diameters of the activated carbon particles 371, wherein the aforementioned diameters refer to the diameters of the through holes of the inlet filter screen 341 and the outlet filter screen 351, so that the activated carbon particles 371 do not flow out of the inlet filter screen 341 and the outlet filter screen 351.

A blocking mechanism 361 is arranged between the water inlet filter screen 341 and the water outlet filter screen 351, and activated carbon particles 371 are arranged between the blocking mechanism 361 and the water inlet filter screen 341.

The blocking mechanism 361 may be a fixed blocking mechanism or a movable blocking mechanism.

In one specific configuration, i.e. the blocking mechanism 361 in fig. 2 is a fixed blocking mechanism, the blocking mechanism 361 is provided with a through hole 381 for the activated carbon particles to pass through.

Thus, when water passes through the second filter element body 30, the water flow impacts the activated carbon particles 371 collected on the water inlet filter screen 341, so as to generate an upward acting force on the activated carbon particles 371, so that the activated carbon particles 371 are collected below the blocking mechanism 361, and under a continuous action, the activated carbon particles 371 pass through the through holes and enter between the blocking mechanism 361 and the water outlet filter screen 351, then the water flow impacts the activated carbon particles 371 between the blocking mechanism 361 and the water outlet filter screen 351 again, so that the activated carbon particles 371 are collected below the water outlet filter screen 351, and then the water flows out from the water outlet filter screen 351, while the activated carbon particles 371 are kept between the blocking mechanism 361 and the water outlet filter screen 351, and when the upward acting force is reduced, the water falls from the through holes 381 of the blocking mechanism 361 to between the blocking mechanism 361 and the water inlet filter screen 341 due to the action of gravity, and is collected on the water inlet filter screen 341.

This kind of water can in proper order with the activated carbon particle 371 on the filter screen 341 of intaking, activated carbon particle 371 below separation mechanism 361 to and the activated carbon particle 371 contact of play water filter screen 351 below, thereby reach and carry out the purpose of abundant contact with activated carbon particle 371 many times, with the filterable mode of once contact in the past, purifying effect promotes greatly.

And, because the utility model discloses in, second filter core body 30 is vertical setting to rivers get into from the bottom, flow out from the top, so activated carbon particle 371 can follow between intaking filter screen 341 and separation mechanism 361 under the effect of rivers, enter into between intaking filter screen 351 and the separation mechanism 361, and at the in-process that rivers effect reduces gradually, activated carbon particle 371 will pass the through-hole of separation mechanism 361 under the action of gravity, return to between intaking filter screen 341 and the separation mechanism 361, ensure next filtration, second filter core body 30 still can exert the efficient and purify the filtering action.

The blocking mechanism 361 is a blocking plate, and a plurality of through holes 381 are formed in the blocking plate. The blocking plate is formed to be adapted to the shape of the second case 331 so that no gap is generated between the blocking plate and the second case 331. Further, the second housing 331 has two ends shrinking and a middle swelling structure, and the cross section of the second housing 331 is an annular structure. The middle bulged part is of a cylindrical structure, so that the cross section of the middle bulged part is of an annular structure, meanwhile, the two ends of the middle bulged part are contracted to be of a cylindrical structure, and the cross section of the two ends of the middle contracted part is also of an annular structure. Meanwhile, the middle bulging part and the two ends shrinking part are in circular arc transition.

The utility model discloses in, in order to reach better filter effect, activated carbon particle 371 should be enough, and the shared total volume after its gathering should account for at least the 2/3 of the volume between separation mechanism 361 and the filter screen 341 of intaking ensures hydroenergy and activated carbon particle 371 and fully contacts.

The through holes 381 should be uniformly distributed on the blocking plate, so that a plurality of activated carbon particles 371 can simultaneously pass through the through holes 381, the passing efficiency is improved, and meanwhile, the activated carbon particles 371 can be prevented from being gathered at a certain position and being blocked.

For example, the through holes 381 are distributed according to a ring shape with the center of the barrier plate as the center of a circle, so as to form a circle of through holes 381, and multiple circles of through holes 381 may be provided, where the center of each circle of through holes 381 is the center of the barrier plate, the diameters of circles formed by each circle of through holes 381 gradually change, that is, the diameters of circles sequentially increase from inside to outside, and the distances between adjacent circles are the same.

The diameter of the through hole 381 should be larger than the diameter of the activated carbon particle 371, so that the activated carbon particle 371 can pass through the through hole 381, because there are more activated carbon particles 371, and in order to make the activated carbon particle 371 pass through the through hole 381 better, the diameter of the through hole 381 should be set to be larger than the diameter of the activated carbon particle 371, for example, the diameter of the through hole 381 is 2-3 times (e.g., 2 times, 2.5 times or 3 times) the diameter of the activated carbon particle 371, so that the activated carbon particle 371 can pass through the through hole 381 more easily. Of course, the diameter of the activated carbon particle 371 refers to the diameter of the largest activated carbon particle 371, since the diameter of the activated carbon particle 371 is not the same.

In addition, in the present invention, in order to make the activated carbon particles 371 pass through the through holes 381 better. The two sides of the through hole 381 can be set to be circular transition grooves, that is, a circular sunken groove is formed at the position where the through hole 381 is formed on the two sides of the barrier plate, and the circular transition grooves are used for guiding the activated carbon particles 371 to pass through the through hole 381, so that the activated carbon particles 371 can pass through the through hole 381 more smoothly.

The circular transition groove is disposed to wrap the through hole 381, i.e., gradually sinking from the outside to the inside until reaching the through hole. The diameter of the outermost layer of the circular transition groove may be set to 2 times the diameter of the through-hole 381 so that there is a sufficient distance to guide the activated carbon particles 371 into the through-hole 381.

In another specific structure, as shown in fig. 4, the second filter element body 30 includes a second casing 332, the second casing 332 is provided with a second water inlet 31 at the bottom, and a second water outlet 32 at the top. Wherein the second water inlet 31 is used for supplying water treated by the first filter element body 20 to enter from the bottom, and the second water outlet 32 is used for supplying water treated by the second filter element body 30 to flow out from the top. A water inlet filter screen 342 is disposed at one end of the second casing 332 close to the second water inlet 31, and a water outlet filter screen 352 is disposed at one end of the second casing 332 close to the second water outlet 32. The functions and structures of the water inlet filter mesh 342 and the water outlet filter mesh 352 are the same as those of fig. 2, and are not described again. A blocking mechanism 362 is arranged between the water inlet filter screen 342 and the water outlet filter screen 352, and activated carbon particles 372 are arranged between the blocking mechanism 362 and the water inlet filter screen 342.

The blocking mechanism 362 is a movable blocking mechanism, that is, the blocking mechanism 362 is movably disposed, and a gap 382 for passing the activated carbon particles 372 is disposed between the blocking mechanism 362 and the second housing 332. A connecting rod 363 is arranged on the blocking mechanism 362, the connecting rod 363 is slidably connected with the second housing 332 through a slider 365, and two limiting devices (not shown) for limiting the blocking mechanism 362 are arranged between the water inlet filter screen 342 and the water outlet filter screen 352, so that the blocking mechanism 362 moves between the two limiting devices.

That is, in this embodiment, the blocking mechanism 362 can slide up and down on the second housing 332 via the connecting rod 363 and the corresponding slider 365. The range of the blocking mechanism 362 sliding up and down is limited by the two limiting devices, when the blocking mechanism 362 slides to the limiting device at the lower part, the blocking mechanism cannot slide downwards continuously, and when the blocking mechanism slides to the limiting device at the upper part, the blocking mechanism cannot slide upwards continuously, so that the blocking mechanism 362 is prevented from colliding with the water inlet filter screen 342 and the water outlet filter screen 352.

The utility model arranges the separation mechanism 362 as a sliding structure, which has the advantages that when the water flow impacts the activated carbon particles 372 gathered on the water inlet filter screen 342, activated carbon particles 372 move upward, and gradually collect below blocking mechanism 362, since gap 382 between blocking mechanism 362 and second housing 332 does not allow activated carbon particles 372 to pass through quickly during the aggregation process, i.e., activated carbon particles 372 will aggregate in small amounts, the water flow will exert an upward force on the entire blocking mechanism 362, and if the blocking mechanism 362 is in a fixed setting, the activated carbon particles 372 will quickly collect under the blocking mechanism 362, because of the large number of activated carbon particles 372, if the activated carbon particles 372 are rapidly gathered in a large amount, the risk of blocking the blocking mechanism 362 may be caused, the speed of the water flow passing through the blocking mechanism 362 is greatly reduced, and the filtering efficiency is affected. The utility model discloses in, because separation mechanism 362 is sliding connection on the second casing 332, so when separation mechanism 362 received ascending effort, separation mechanism 362 can drive through its connecting rod 363 slider 365 upwards slides, whole separation mechanism 362 then upward movement like this, active carbon granule 372 can not gather in separation mechanism 362 below fast like this, but can be along with separation mechanism 362 upward movement together to in separation mechanism 362 upward movement in-process, active carbon granule 372 constantly rubs between clearance 382, improves active carbon granule 372 and passes through the speed of clearance 382, thereby has avoided active carbon granule 372 to block up the possibility of separation mechanism 362.

The width of the gap 382 should be larger than the diameter of the activated carbon particle 372, so that the activated carbon particle 372 can pass through the gap 382, and in order to improve the passing efficiency of the activated carbon particle 372, the width of the gap 382 can be set to be larger, but the width of the gap 382 should not be too large, otherwise the activated carbon particle 372 will not be gathered a little below the blocking mechanism 362, and a good purifying effect cannot be achieved. That is, the activated carbon particles 372 should not be collected under the blocking mechanism 362 in a large amount (which may cause clogging problem) and should not be collected under the blocking mechanism 362 (which may cause poor purification effect problem). In the present invention, the width of the gap 382 may be set to 3 to 5 times (e.g., 4 times) the width of the activated carbon particle 372, so that the activated carbon particle 372 can pass through the gap 382 at a better speed. And the gap 382 between the blocking mechanism 362 and the second housing 332 is the same everywhere, i.e., the width of the gap 382 is constant, which helps to prevent the activated carbon granules 372 from being packed in one position and clogging.

Further, the second housing 332 includes a central housing located in the middle, and the water inlet filter mesh 342 and the water outlet filter mesh 352 are located at two ends of the central housing, which is a cylindrical housing. Thus, the cross section of the central housing is an annular structure, and since the water inlet filter screen 342 and the water outlet filter screen 52 are located at two ends of the central housing, the two limiting devices are necessarily located at the central housing, so that the blocking mechanism 362 can only slide up and down on the central housing, and the central housing is a cylindrical housing, so that the blocking mechanism 362 can smoothly slide up and down along the central housing.

Further, the blocking mechanism 362 is a blocking plate, the shape of the blocking plate is matched with that of the central housing, and the gap is formed between the periphery of the blocking plate and the central housing.

Since the width of the gap 382 is the same everywhere, and the central housing is a cylindrical housing, the shape of the blocking plate is necessarily circular, and the center of the blocking plate coincides with the center of the central housing, so that the purpose of matching the shape of the blocking plate with the shape of the central housing can be achieved.

Further, the number of the sliding blocks 365 is two, and the two sliding blocks are respectively connected to two ends of the connecting rod 363, specifically, a cross rod 364 is arranged above the connecting rod 363, and the sliding blocks 365 are arranged at two ends of the cross rod 364. The purpose of the two sliders 365 is to make the blocking mechanism 362 more stable in sliding and more evenly stressed.

Further, the inner wall of the second housing 332 is provided with a sliding rail 333, and the side edge of the sliding block 365 is provided with a sliding groove for sliding on the sliding rail 333. By providing the sliding groove, the blocking mechanism 362 can slide on the sliding rail and cannot fall off from the sliding rail.

Since the sliding block 365 needs to slide along the sliding rail 333, the shape of the sliding block 365 is preferably adapted to the shape of the central housing, for example, the sliding block 365 is configured as a circular arc-shaped sliding block, so that the size of the sliding block can be saved, and the sliding is also facilitated. One surface of the circular arc-shaped sliding block close to the central shell is circular arc-shaped, and the other opposite surface of the circular arc-shaped sliding block is also preferably circular arc-shaped, namely the two opposite surfaces of the circular arc-shaped sliding block are both circular arc-shaped.

In the two structures, a stirring device for stirring the activated carbon particles is preferably arranged on each blocking mechanism.

As shown in fig. 5, the stirring device includes a motor device 390 disposed on the blocking mechanism 361, and a stirring shaft 391 vertically connected to the motor device 390, one end of the stirring shaft 391 extends between the blocking mechanism 361 and the water inlet filter screen 341, the other end extends between the blocking mechanism 361 and the water outlet filter screen 351, and both ends of the stirring shaft 391 are connected with stirring blades 392. The motor device 390 may be disposed outside the second housing 331, or may be disposed on the blocking mechanism 361, and when disposed on the blocking mechanism 361, the motor device 390 needs to be subjected to waterproof sealing treatment.

The purpose of setting up agitating unit is in order to stir the active carbon granule 371 between separation mechanism 361 and the filter screen 341 of intaking, make active carbon granule 371 wherein be easier to enter into between separation mechanism 361 and the filter screen 351 of intaking between separation mechanism 361 and the filter screen 341 of intaking, also stir the active carbon granule 371 that is in between separation mechanism 361 and the filter screen 351 of intaking simultaneously, make active carbon granule 371 wherein be easier to enter into between separation mechanism 361 and the filter screen 351 of intaking, thereby strengthen the flow of active carbon granule 371 in two spaces, be unlikely to that active carbon granule 371 blocks up in separation mechanism 361 below or top, improve water velocity, ensure purification efficiency.

Meanwhile, the two ends of the stirring shaft 391 are connected with the stirring blades 392 at the same time, so that the stirring blades 392 at the two ends can be driven to rotate at the same time by using one motor device 390, the stirring efficiency is greatly improved, and the energy is saved.

It is to be understood that the invention is not limited to the above-described embodiments, and that modifications and variations may be made by those skilled in the art in light of the above teachings, and all such modifications and variations are intended to be included within the scope of the invention as defined in the appended claims.
