Description
Technical field
Water purifier technical field, the particularly one instrument of exempting from that the present invention relates to pulls out joint design filter core soon.
Background technology
China, in family expenses, commercial drinking water treatment technology, independently changes core for realizing user, solves the difficult problem after sale that manufacturer exempts to on-site install, safeguard.The deserted filter core of general employing realizes.
Deserted filter core generally divides two kinds, and one is that plug-in abandons filter core, and another kind is that threaded port type abandons filter core.
But plug-in abandons filter core at present, and the quick union dismounting and change of use is comparatively inconvenient.Easily because misoperation causes joint elastic claw to damage or filter core intake-outlet is impaired, affect sealing and cause leakage accident.It is be spirally connected by the screw socket of filter flask and the Connection Block of pipeline that threaded port type abandons filter core, and this connected mode, when more renew cartridge, needs to use specific purpose tool to back out after filter flask more renew cartridge, owing to being subject to the restriction in space during operation, operates and bother very much.
Summary of the invention
The present invention, in order to solve current deserted filter core when changing, the complicated operation of existence, needing specific purpose tool and easily damaging the problem of filter core and the one instrument of exempting from that provides pulls out joint design filter core soon.
For reaching above-mentioned functions, technical scheme provided by the invention is:

Fig. 4 is the profile of embodiment two.
Detailed description of the invention
Below in conjunction with accompanying drawing 1 to accompanying drawing 4, the present invention is further elaborated:
Embodiment one:
One is as depicted in figs. 1 and 2 exempted from instrument and is pulled out joint design filter core soon, comprise filter core head 1 and filter element upper cover 2, the intake-outlet of filter core is positioned on filter core head 1, the filter element upper cover 2 of corresponding intake-outlet position offers the via hole 21 allowing connecting tube to pass through, in the present embodiment, the quantity of intake-outlet is 3, comprises a water inlet, a delivery port and a dense water delivery port.
The intake-outlet position of filter core head 1 is provided with fast interface 3, fast interface 3 comprises O shape circle 31, retainer ring 32 and elastic card claw 33, in the present embodiment, elastic card claw 33 comprises the elastic card of 4 even circumferential distributions, elastic card claw 33 is set in retainer ring 32, the upper surface external diameter of elastic card claw 33 is greater than the internal diameter of retainer ring 32 thus ensures that elastic card claw 33 does not fall into the inside of retainer ring 32, in the present embodiment, by being provided with boss 331 in the upper end of elastic card claw 33, the external diameter of boss 331 is greater than the internal diameter of retainer ring 32 thus ensures that elastic card claw 33 does not fall into the inside of retainer ring 32, the bottom of retainer ring 32 is provided with interior frustum 321.
The upper end of filter core head 1 offers spacing loose slot B15, the medial surface of the upper end of filter element upper cover 2 is provided with several back-offs 23, the height of back-off 23 is less than the groove width of spacing loose slot B15, utilize coordinating of back-off 23 and loose slot B, can not take out easily after filter element upper cover 2 and filter core head 1 are assembled, and can ensure that again filter element upper cover 2 can move axially certain distance relative to filter core head 1.
Use procedure of the present invention is as follows:
As shown in Figure 1, in the present embodiment, the present invention coordinates one end to be that the snap joint A6 of straight tube end uses, and snap joint A6 is city dealer product, can directly buy from the market.First time is when installing, snap joint A6 is connected with supply channel, the other end of snap joint A6 and straight tube end insert in fast interface 3, during connection, ensure that straight tube end inserts in case leak-stopping water in the O shape circle 31 of fast interface 3, when directly pulling out straight tube end outward, elastic card claw 33 can be interferenceed with retainer ring 32, now elastic card claw 33 blocks straight tube end, thus prevents straight tube end from extracting from fast interface 3.
When filter core reaches service life, need more renew cartridge time, user only needs a little down to press filter element upper cover 2, filter element upper cover 2 is made to push down the boss 331 of the elastic card claw 33 of fast interface 3, thus ensure that elastic card claw 33 does not block straight tube end, therefore user just can extract snap joint A6 like a cork outward, takes out filter core.It should be noted that, when pressure presses filter element upper cover 2, the boss 331 of the elastic card claw 33 of all fast interfaces 3 can be pushed down, therefore can the multiple snap joint A6 of disposable dismounting.
In the process used, user can not use snap joint A6 according to actual conditions, and feed pipe is directly accessed fast interface 3 of the present invention.
Embodiment two:
One is as shown in Figure 3 and Figure 4 exempted from instrument and is pulled out joint design filter core soon, comprise filter core head 1 and filter element upper cover 2, the intake-outlet of filter core is positioned on filter core head 1, the filter element upper cover 2 of corresponding intake-outlet position offers the via hole 21 allowing connecting tube to pass through, in the present embodiment, the quantity of intake-outlet is 3, comprises a water inlet, a delivery port and a dense water delivery port.
Filter element upper cover 2 and filter core head 1 clamping, the upper end of filter core head 1 is provided with the first buckle 11 and is provided with spacing loose slot 13 between the second buckle 12, first buckle 11 and the second buckle 12, filter element upper cover 2 is provided with the draw-in groove 22 matched with the second buckle 12.When filter element upper cover 2 is pressed onto the end toward the direction of filter core head 1, draw-in groove 22 can match with the second buckle 12, thus clamping filter element upper cover 2; When filter element upper cover 2 is up pulled out, draw-in groove 22 is deviate from from the second buckle 12, now filter element upper cover 2 can not drop out from filter core head 1 again in the axial direction freely-movable along filter core head 1 between the first buckle 11 and the second buckle 12.
The intake-outlet of filter core head 1 is provided with tube connector 14.In the present embodiment, instrument of exempting from pulls out joint design filter core soon and also comprises three quick unions 4, and filter element upper cover 2 is provided with the groove 24 allowing the interface end of quick union 4 to pass through, via hole 21 is arranged on the bottom surface of groove 24.
Use procedure of the present invention is as follows:
First time is when installing, after one end of snap joint is connected with supply channel, filter element upper cover 2 is pressed on filter core head 1 makes draw-in groove 22 fastening on the second buckle 12, thus make filter element upper cover 2 fastening on filter core head 1, then the tube connector 14 of filter core head 1 is directly inserted in the other end of snap joint, complete connection.Snap joint is city dealer product, can directly buy from the market.
When filter core reaches service life or other reason, need more renew cartridge time, user need exert oneself up to pull out filter element upper cover 2 a little, the draw-in groove 22 of filter element upper cover 2 is deviate from from the second buckle 12, such filter element upper cover 2 just can be movable between the first buckle 11 and the second buckle 12, user pulls out filter element upper cover 2 toward the direction of quick union 4 again, the plane of now pulling out groove 24 place of filter element upper cover 2 can be pressed onto the elastic card claw of quick union 4, drive multiple quick union 4 once to extract again, realize quick-detachment filter core.
The above embodiment, just preferred embodiments of the present invention, be not limit practical range of the present invention, therefore all equivalences done according to structure, feature and the principle described in the present patent application the scope of the claims change or modify, and all should be included in patent claim of the present invention.
