Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is described further;
Fig. 1 is the structural representation of the embodiment of the present invention;
Fig. 2 is the partial enlargement structural representation in Fig. 1;
Fig. 3 is that embodiment of the present invention middle sleeve covers the structural representation being connected with button.
Embodiment
Referring to figs. 1 through Fig. 3, the anti-self-locking formula filter core that leaks of the present invention's one, the sleeve 20 comprising filter cylinder 10 and be located in filter cylinder 10, there is between filter cylinder 10 and sleeve 20 annular circulation inner chamber 30, sleeve 20 top has the through hole being connected annular circulation inner chamber 30 and sleeve 20 inner chamber, sleeve 20 bottom center outwards extends to form annular inner wall 21, filter cylinder 10 bottom center outwards extends to form annular outer wall 11, the annular cavity 12 that gap between annular outer wall 11 with annular inner wall 21 is formed with annular circulation inner chamber 30 is connected, annular inner wall 21 forms the cylindrical cavity 22 with sleeve 20 intracavity inter-connection, the first containment member 40 of elasticity shutoff annular cavity 12 it is provided with in annular cavity 12, the 2nd containment member 50 of elasticity shutoff cylindrical cavity 12 it is provided with in cylindrical cavity 12.
In the present embodiment, annular cavity 12 is as the water-in of filter core, cylindrical cavity 12 is as the water outlet of filter core, at sleeve 20 built with water purification filtration material, water enters in annular circulation inner chamber 30 through annular cavity 12, flow into sleeve 20 inner chamber at the through hole through sleeve 20 top to purify, more outwards flow out through cylindrical cavity 12.
Filter core of the present invention and the base with circulation duct with the use of, when filter core is plugged on base, move inward under the effect of the first containment member 40 in filter core bottom and the 2nd containment member 50 bilge construction outside and annular cavity 12 and cylindrical cavity 12 are communicated with the circulation duct in base.
Specifically, first containment member 40 comprises shutoff ring 41 and the first return spring 42, shutoff ring 41 is sleeved on annular inner wall 21 and reciprocally moves, first return spring 42 is sleeved on annular inner wall 21 and and is in shutoff ring 41 and sleeve 20 bottom outward, the inner side-wall of annular outer wall 11 is step-off construction, wherein, radially-inwardly shrink in the middle part of the inner side-wall of annular outer wall 11 and form one section of inclined-plane 43, the inner sidewall upper portion of annular outer wall 11 and bottom are flat segments, the outer sidewall diameter of shutoff ring 41 equals or is slightly less than the inner side-wall lower diameter of annular outer wall 11, annular outer wall 11 bottom is provided with radially-inwardly protrude first and keeps out flange 44, first internal diameter keeping out flange 44 is less than the outer sidewall diameter of shutoff ring 41, thus limit shutoff ring 41 and outwards deviate from, it is embedded with sealing-ring at shutoff ring 41 outer side wall, on the outer side wall of annular inner wall 21, inner side-wall bottom opposite position with annular outer wall 11 is embedded with sealing-ring.
Not having under outside structure function, the first return spring 42 promotes shutoff ring 41 to move between the inner side-wall bottom of annular outer wall 11 and annular inner wall 21 by elastic force, relies on shutoff ring 41 and sealing-ring that annular cavity 12 is carried out shutoff. When there is the effect of outer bilge construction, shutoff ring 41 is pushed and the elastic force that overcomes the first return spring 42 moves inward, and now annular cavity 12 communicates with outside.
2nd containment member 50 comprises plugging block, the outward extending motion bar 51 from plugging block center, and the 2nd return spring 52, annular inner wall 21 top extends radially inwardly and forms fixing flange 23, fixing flange 23 center has the runner being connected sleeve 20 inner chamber and cylindrical cavity 22, motion bar 51 inserts in runner and makes plugging block be in cylindrical cavity 22, the diameter of motion bar 51 is less than runner to arrive, namely communicate all the time between sleeve 20 inner chamber and cylindrical cavity 22, 2nd return spring 52 is sleeved on motion bar 51 and and is between plugging block and fixing flange 23 outward, wherein, plugging block comprises the first disk 53, 2nd disk 54 and connection the first disk 53 are connected post 55 with the center of the 2nd disk 54, connect post outer sheath at center and sealing-ring is housed, motion bar 51 bottom is fixedly connected with the first disk 53 center, the external diameter of the first disk 53 is the external diameter being greater than the 2nd disk 54, it is provided with the radially-inwardly protrude the 2nd in annular inner wall 21 bottom and keeps out flange 56, the external diameter of the first disk 53 is greater than the internal diameter that the 2nd keeps out flange 56, the external diameter of the 2nd disk 54 is less than the internal diameter that the 2nd keeps out flange 56, thus, 2nd disk 54 can be kept out flange 56 from the 2nd and outwards be stretched out a segment distance, first 53, disk is kept out flange 56 by the 2nd and is supported restriction.
Not having under outside structure function, the 2nd return spring 52 promotes plugging block to move to the 2nd and keep out flange 56 place by elastic force, and the first disk 53 in plugging block and sealing-ring and the 2nd are kept out flange 56 and be in close contact, thus cylindrical cavity 22 is carried out shutoff.When there is the effect of outer bilge construction, plugging block is pushed and the elastic force that overcomes the 2nd return spring 52 moves inward, and flange 56 is kept out in plugging block disengaging the 2nd, and now, cylindrical cavity 22 communicates with outside.
As preferably, sleeve 20 top has been fastened and connected lid 24, two side, sleeve 20 top symmetry is formed respectively buckles block 25, the corresponding formation respectively of button lid 24 both sides of edges end detains, with button block 25, the button hole 26 closed, on button lid 24, array distribution is formed and is connected the through hole of sleeve 20 inner chamber with annular circulation inner chamber 30, by being fastened and connected of button block 25 and button hole 26, it is possible to conveniently dismount and detain lid 24, thus facilitate and filter material wherein is changed.
As preferably, the outer wall of sleeve 20 being along the circumferential direction interval with multiple positioning convex strip 27, under the effect of positioning convex strip 27 so that the stable center position being in filter cylinder 10 of sleeve 20, sleeve 20 can be effectively avoided to move.
Above in conjunction with accompanying drawing, embodiments of the present invention are explained in detail, but the invention is not restricted to above-mentioned enforcement mode, in the ken that described technical field those of ordinary skill possesses, it is also possible to make various change under the prerequisite not departing from objective of the present invention.
