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

Referring to fig. 2, the second filter element body 30 includes a second casing 33, a second water inlet 31 is disposed at the bottom of the second casing 33, and a second water outlet 32 is disposed 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 aperture of the water inlet filter screen 34 and the water outlet filter screen 35 is smaller than the diameter of the activated carbon particles 37, wherein the aforementioned aperture refers to the diameter 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 fixed separation mechanism 36 between filter screen 34 and the play water filter screen 35 of intaking, be provided with activated carbon granule 37 between separation mechanism 36 and the filter screen 34 of intaking, be provided with the through-hole 38 that is used for activated carbon granule 37 to pass on the separation mechanism 36.

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 through holes 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 through holes 38 and enter between the blocking mechanism 36 and the water outlet filter screen 35, then the water flow impacts the activated carbon particles 37 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 when the upward acting force becomes small, the water flow falls into between the blocking mechanism 36 and the water inlet filter screen 34 from the through holes 38 of the blocking mechanism 36 due to the action of gravity, 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 separation mechanism 36's through-hole 38 under the action of gravity, return to between filter screen 34 and the separation mechanism 36 of intaking, ensure next filtration, second filter core body 30 still can exert the efficient and purify the filtering action.

Further, the blocking mechanism 36 is a blocking plate, and the blocking plate is provided with a plurality of through holes 38. The shape of the baffle plate should be adapted to the shape of the second housing 33 so that no gap is created between the baffle plate and the second housing 33.

Further, the second housing 33 has two contracted ends and a bulged middle, and the cross section of the second housing 33 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 37 should be sufficient, and the shared total volume after its gathering should account for at least 2/3 of the volume between separation mechanism 36 and the filter screen 34 of intaking ensures hydroenergy and activated carbon particle 37 fully contact.

The through holes 38 should be uniformly distributed on the blocking plate, so that a plurality of activated carbon particles 37 can simultaneously pass through the through holes 38, the passing efficiency is improved, and meanwhile, the activated carbon particles 37 can be prevented from being gathered at a certain position and being blocked.

For example, the through holes 38 are distributed in an annular shape with the center of the blocking plate as the center of the circle, so as to form a circle of through holes 38, and a plurality of circles of through holes 38 may be provided, the center of the circle of through holes 38 is the center of the blocking plate, the diameter of the circle formed by each circle of through holes 38 gradually changes, that is, the diameter gradually increases from inside to outside, and the distances between adjacent circles are the same.

The diameter of the through hole 38 should be larger than the diameter of the activated carbon particle, so that the activated carbon particle 37 can pass through the through hole 38, because there are more activated carbon particles 37, in order to make the activated carbon particle 37 better pass through the through hole, the diameter of the through hole 38 should be set to be larger than the diameter of the activated carbon particle 37, for example, the diameter of the through hole 38 is 2-3 times (for example, 2 times, 2.5 times or 3 times) the diameter of the activated carbon particle 37, so that the activated carbon particle 37 can pass through the through hole 38 more easily. Of course, the diameter of the activated carbon particles 37 is different, and the diameter of the activated carbon particles 37 refers to the diameter of the largest activated carbon particle 37.

In addition, in the present invention, in order to make the activated carbon particles 37 better pass through the through holes 38. It is also possible to provide both sides of the through hole 38 with circular transition grooves, i.e. there is a circular depressed groove at the position where both sides of the blocking plate are provided with the through hole 38, and this circular transition groove functions to guide the activated carbon particles 37 through the through hole 38, so that the activated carbon particles 37 can pass through the through hole 38 more smoothly.

The circular transition groove is arranged to wrap around the through hole 38, i.e. to gradually sag 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 38 so that there is sufficient distance to guide the activated carbon particles into the through-hole.

Further, first filter element body 20 includes first casing, first casing top is provided with first water inlet, first casing bottom is provided with first delivery port, the cotton filter layer of PP set up in between first water inlet and the first delivery port.
