Can be sprayed water in the length range of flush pipe 2 and in the range of 360 degree, so as in scope as big as possible to filter material
It is rinsed, strengthens developing result.
Preferably, the free end (i.e. that one end away from base 1) of flush pipe 2 is provided with end plate (not shown), Ye Jichong
The free end for washing pipe 2 is not open design, to prevent flushing water from directly being vomited from end.Preferably, equally set on end plate
Hole for water spraying is equipped with, and preferably, angle be present between the axis of the hole for water spraying on end plate and the axis of flush pipe 2 so that this
The water (flow) direction ejected in a little hole for water sprayings is oblique top, so as to realize to the film beyond the length range of flush pipe 2
Silk part is rinsed, and further improves developing result.
Preferably, as depicted in figs. 1 and 2, the base 1 has tubular structure, on the barrel 12 of the tubular structure
Provided with the first boss 13 for being connected with the putamina 3, circumferentially extending of the first boss 13 along the barrel 12.
Accordingly, as shown in figure 4, second boss 31 can be set on putamina 3, circumferentially extending of the second boss 31 along putamina 3.Work as bottom
Seat 1 with putamina 3 fit together when, can by first boss 13 and second boss 31 supporting each other on filter core axis direction
Lean on and realize axial limiting, prevent that base 1 and putamina 3 are separated from each other.
Preferably, a pair of first boss 13, each first boss 13 are symmetrically provided with the barrel 12 of the tubular structure
The of length no more than girth of barrel 12 of circumferentially extending a quarter.Accordingly, the second boss 31 on putamina 3 is also pair
It is provided with a pair with claiming, and the circumferentially extending length of each second boss 31 is also no more than a quarter of the girth of putamina 3.
When such two pairs of boss carry out spacing simultaneously, the uniform force between base 1 and putamina 3 can be ensured, and ensure
Boss circumferential size reaches maximization.
So, in specific installation, base 1 can be first made to be missed one another out with the boss on putamina 3, then by flush pipe
2 stretch into putamina 3 and insert the inside of filter material, are rotated against for example after axially assembling in place, then by base 1 and putamina 3
90 °, you can first boss 13 is pressed against each other with second boss 31, complete installation.
Preferably, circumferential spacing knot is provided with least one of the first boss 13 and the second boss 31
Structure, such as the bulge-structure of circumferential one end of corresponding boss can be provided in, it is located at second boss 31 as shown in Figure 4
The bulge-structure 33 of circumferential one end.The circumferential position limiting structure can cause base 1 to rotate against certain angle (such as with putamina 3
90 °) after just by circumferential spacing, can not further rotate, now, first boss 13 and second boss 31 can be complete in the circumferential
It is overlapping.In such manner, it is possible to effectively prevent from rotating between base 1 and putamina 3 deficiency or rotation it is excessive and cause first boss 13 with
The problem of lap deficiency between second boss 31, ensure bonding strength.Thus, between base 1 and putamina 3 when mounted only
It can in one direction be rotated, and then be rotated in opposite direction in dismounting.
Preferably, as shown in fig. 7, filter element cleaning structure of the present invention can also include being arranged on the side of putamina 3
Groove 34 on wall and the cleaning brush 35 for scrubbing the filter material (such as film wire 41), axial direction of the groove 34 along the putamina 3 are prolonged
Stretch, at least a portion of the cleaning brush 35 can be probeed into the putamina 3 through the groove 34, to scrub the filter material.
That is, when flush pipe 2 outwards rinses filter material from the central position, it is past for the flushing strength of the part filter material of periphery
Toward deficiency, in this case, this part filter material of periphery is scrubbed using cleaning brush 35, to ensure that cleaning is more comprehensively thorough
Bottom.Specifically, operator can manually manipulate length direction of the cleaning brush 35 along groove 34 and move back and forth, and complete to corresponding filter material
Cleaning, other drive mechanisms can also be passed through and drive length direction of the cleaning brush 35 along groove 34 to move back and forth.
Preferably, the quantity of the groove 34 is two or more, so as to expand the scrub scope of cleaning brush 35.
Preferably, the cleaning brush 35 is arranged on by the groove 34 in the side wall of the putamina 3, and the cleaning brush
35 can move along the length direction of the groove 34.In present embodiment, cleaning brush 35 is installed on inner core of filter element all the time, is being needed
When cleaning, filter core is taken out from the outer casing (such as filter flask) of filter core, can be scrubbed with manipulating cleaning brush 35, meanwhile,
Coordinate the flushing of flush pipe 2, cleaning performance can be better achieved, and cleaning efficiency is high.
On the basis of above-mentioned work, the second aspect of the present invention additionally provides a kind of water purifier filter core, such as Fig. 5-6 institutes
Show, it includes putamina 3 and the filter material being arranged in the putamina 3, and also includes the foregoing filter element cleaning knot of the present invention
