Detailed description of the invention:

As Figure 1-Figure 2, the extruded activated carbon filter element of interchangeable union joint, including filter cylinder 1, filter cylinder 1 is internal is installed with extruded activated carbon core 3 by upper cover 2, being provided with gap between extruded activated carbon core 3 and filter cylinder 1 inwall, the middle part of extruded activated carbon core 3 is provided through central canal 4, and the bottom of central canal 4 is provided with shrouding 5, being provided with bonnet 6 on filter cylinder 1 below shrouding 5, filter cylinder 1 head is detachably provided with connection conversion head 8 by Horse hoof buckle 7. Utilize Horse hoof buckle 7 to install at filter cylinder 1 head and connect conversion head 8, by changing different connection conversion heads 8, thus realizing the purpose of extruded activated carbon core 3 wildcard of different manufacturers.

As it is shown on figure 3, the structure of Horse hoof buckle 7 is: include horseshoe-shaped clip matrix 71, end clip projection 72 is all extended at the two ends of clip matrix 71 inside clip matrix 71, and the middle part of clip matrix 71 is provided with clip projection 73 in the middle part of at least one. During use, as in figure 2 it is shown, select two symmetrical Horse hoof buckles 7, then end clip projection 72 and middle part clip projection 73 are inserted and be arranged in the draw-in groove connecting conversion head 8 and filter cylinder 1 head, it becomes possible to realize filter cylinder 1 and connect the fixing of conversion head 8. Whole process is simple and convenient, stable connection, it is simple to dismounting and change connects conversion head 8.

In order to increase the structural strength of Horse hoof buckle 7, middle part clip projection 73 and end clip projection 72 and the one-body molded setting of clip matrix 71, the joint of middle part clip projection 73 and clip matrix 71 adopts arc transition.The Horse hoof buckle 7 of plastic material can adopt injection mo(u)lding, and manufacturing process is simple. And arc transition is it can be avoided that produce stress and concentrate, and increases the structural strength of Horse hoof buckle 7, increases the service life.

As it is shown on figure 3, the inner side profile of middle part clip projection 73 is made up of three cambered surfaces, inner side profile includes arcuate engagement surface 74, and the two ends of arcuate engagement surface 74 are connected with clip matrix 71 by arc guide surface 75. Arc guide surface 75 plays guide effect when Horse hoof buckle 7 inserts draw-in groove, identical with the structure of middle part clip projection 73 after the mutual split of two end clip projections 72 of clip matrix 71 both sides.

It addition, when actually used, it is possible to the size according to Horse hoof buckle, select the quantity of suitable middle part clip projection 73, the quantity of middle part clip projection 73 is 1, or is 2, or is 3. As long as the quantity of middle part clip projection 73 ensure that filter cylinder 1 and 8 stable connections that are connected conversion head.

As in figure 2 it is shown, be provided with O RunddichtringO between described connection conversion head 8 and filter cylinder 1 head. O RunddichtringO ensure that is changing the sealing property connected between conversion head 8 and filter cylinder 1 head, it is prevented that water seepage.

As shown in Figure 4, the structure connecting conversion head 8 is: including conversion head matrix 81, the top of conversion head matrix 81 is provided with water inlet 82 and outlet 83, and the side of conversion head matrix 81 is preset with for the draw-in groove fixing with Horse hoof buckle 7. Connect conversion head 8 in addition to convenient and consider between bottle fixing, being additionally provided with hole 84, location at the top of rotary head matrix.

Extruded activated carbon filter cartridge construction in above-described embodiment solves the problem can not mated and exchange between the extruded activated carbon filter element that existing different manufacturers produces. Also being able to a certain degree increase the utilization rate of extruded activated carbon core 3, whole filter element technique is simple, steady quality, good seal performance simultaneously.

Above in conjunction with accompanying drawing, embodiments of the invention are explained in detail, but the present invention is not limited to above-described embodiment, in the ken that those of ordinary skill in the art possess, it is also possible under the premise without departing from present inventive concept, make various change.
