As shown in fig. 2, the second filter element body 30 comprises a second casing 33, a second water inlet 31 is arranged at the bottom of the second casing 33, a second water outlet 32 is arranged at the top of the second casing 33, 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.

The one end that is close to second water inlet 31 in the second casing 33 is provided with into water filter screen 34, the one end that is close to second delivery port 32 in the second casing 33 is provided with out water filter screen 35. The water inlet filter screen 34 and the water outlet filter screen 35 can filter water entering and flowing out of the second filter element body 30 on one hand, and can block the later-mentioned activated carbon particles 37 on the other hand, so that the activated carbon particles 37 are ensured not to flow out of the second filter element body 30. That is, the apertures of the water inlet filter screen 34 and the water outlet filter screen 35 are smaller than the diameters of the activated carbon particles 37, wherein the aforementioned apertures refer to the diameters of the through holes of the water inlet filter screen 34 and the water outlet filter screen 35, so that the activated carbon particles 37 do not flow out of the water inlet filter screen 34 and the water outlet filter screen 35.

Be provided with movable separation mechanism 36 between filter screen 34 and the play water filter screen 35 of intaking, separation mechanism 36 and intake are provided with activated carbon granule 37 between the filter screen 34, separation mechanism 36 with be provided with the clearance 38 that is used for activated carbon granule 37 to pass between the second casing 33. Namely, the activated carbon particles 37 are disposed between the blocking mechanism 36 and the water inlet filter screen 34, and the activated carbon particles 37 can also pass through the blocking mechanism 36 through the gap 38, so as to reach between the blocking mechanism 36 and the water outlet filter screen 35.

Thus, when water passes through the second filter element body 30, water flow impacts the activated carbon particles 37 gathered on the water inlet filter screen 34, so as to generate an upward acting force on the activated carbon particles 37, so that the activated carbon particles 37 are gathered below the blocking mechanism 36, and under a continuous action, the activated carbon particles 37 pass through the gap and enter between the blocking mechanism 36 and the water outlet filter screen 35, then the water flow impacts the activated carbon particles between the blocking mechanism 36 and the water outlet filter screen 35 again, so that the activated carbon particles 37 are gathered below the water outlet filter screen 35, then the water flows out from the water outlet filter screen 35, and the activated carbon particles 37 are kept between the blocking mechanism 36 and the water outlet filter screen 35, and fall into between the blocking mechanism 36 and the water inlet filter screen 34 from the gap 38 due to the action of gravity when the upward acting force becomes small, and collects on the influent filter screen 34.

This kind of water can be in proper order with the active carbon granule 37 on the filter screen 34 of intaking, the active carbon granule 37 of separation mechanism 36 below to and the active carbon granule 37 below the filter screen 35 of exhaling contact, thereby reach and carry out the purpose of abundant contact with active carbon granule 37 many times, with the filterable mode of 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 from the top, so under the effect of rivers active carbon granule 37 can follow between filter screen 34 and the separation mechanism 36 of intaking, enter into between play water filter screen 35 and the separation mechanism 36, and at the in-process that rivers effect reduces gradually, active carbon granule 37 will pass under the action of gravity the clearance returns to between filter screen 34 and the separation mechanism 36 of intaking, ensures the filtration of next time, second filter core body 30 still can exert the efficient and purify the filtration effect.

A connecting rod 361 is arranged on the blocking mechanism 36, the connecting rod 361 is connected with the second shell 33 through a sliding block 363 in a sliding mode, and two limiting devices (not shown) used for limiting the blocking mechanism 36 are arranged between the water inlet filter screen 34 and the water outlet filter screen 35, so that the blocking mechanism 36 can move between the two limiting devices.

That is, in the present invention, the blocking mechanism 36 may slide up and down on the second housing 33 through the connecting rod 361 and the corresponding slider 363. And the range that separation mechanism 36 slides from top to bottom is restricted by two stop devices, when sliding to the stop device of below, then can't continue to slide downwards, when sliding to the stop device of top, then can't continue to slide upwards, the benefit of doing so is to avoid separation mechanism 36 and water inlet filter screen 34 and play water filter screen 35 to produce the collision.

The utility model arranges the separation mechanism 36 as a sliding structure, which has the advantages that when the water flow impacts the activated carbon particles 37 gathered on the water inlet filter screen 34, the activated carbon particles 37 move upwards and gradually gather below the separation mechanism 36, since the gap 38 between the blocking mechanism 36 and the second housing 33 does not allow the activated carbon particles 37 to pass through quickly during the aggregation process, i.e., the activated carbon particles 37 are aggregated in a small amount, the water flow will exert an upward force on the entire blocking mechanism 36, and if the blocking mechanism 36 is in a fixed arrangement, the activated carbon particles 37 will quickly collect under the blocking mechanism 36, because of the large number of activated carbon particles 37, if the activated carbon particles 37 are rapidly gathered in a large amount, there is a risk that the blocking mechanism 36 is blocked, so that the speed of water flowing through the blocking mechanism 36 is greatly reduced, and the filtering efficiency is affected. The utility model discloses in, because separation mechanism 36 is sliding connection on the second casing 33, so when separation mechanism 36 received ascending effort, separation mechanism 36 can drive through its connecting rod 361 slider 363 upwards slides, whole separation mechanism 36 then upward movement like this, active carbon granule 37 can not gather in separation mechanism 36 below fast like this, but can be along with separation mechanism 36 upward movement together to in separation mechanism 36 upward movement process, active carbon granule 37 constantly rubs between clearance 38, improves active carbon granule 37 and passes through clearance 38's speed, thereby has avoided the possibility that the active carbon granule blockked up separation mechanism when improving purification efficiency.

The width of the gap 38 should be larger than the diameter of the activated carbon particles, so that the activated carbon particles 37 can pass through the gap 38, in order to improve the passing efficiency of the activated carbon particles 37, the width of the gap 38 may be set to be larger, but the width of the gap 38 should not be too large, otherwise the activated carbon particles 37 will not be gathered a little below the blocking mechanism 36, and a good purifying effect cannot be achieved. That is, it is not preferable that the activated carbon particles 38 are accumulated under the blocking mechanism 36 in a large amount (which causes a problem of clogging), nor under the blocking mechanism 36 (which causes a problem of poor purification effect). In the present invention, the width of the gap 38 can be set to 3 to 5 times (e.g. 4 times) that of the activated carbon particles 37, so that the activated carbon particles 37 can pass through the gap at a better speed. And the gap 38 between the blocking mechanism 36 and the second housing 33 is the same everywhere, that is, the width of the gap 38 is constant, which helps to prevent the activated carbon granules 37 from being piled up in one position and from being blocked.

By providing the sliding groove, the blocking mechanism 36 can slide on the sliding rail 331 and cannot fall off from the sliding rail 331.

Since the slider 363 needs to slide along the slide rail, the shape of the slider 363 is preferably adapted to the shape of the central housing, for example, the slider 363 is configured as an arc slider, which can save the slider volume and facilitate sliding. 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.
