A preferred version of the present utility model, wherein, described positioning convex is arranged on the outer wall of bottle, and described locating slot is arranged on the inwall of bottom end cover.Adopt the benefit of this preferred version to be, because projection is positioned on the outer wall of bottle, thereby guarantee that bottle inwall is smooth, be convenient to place filter core.
A preferred version of the present utility model, wherein, the lower end of the inwall of described bottom end cover is provided with multiple projections of along the circumferential direction arranging, and between adjacent two projections, is formed with gap, and this gap forms described locating slot.Adopt the object of this preferred version to be, be not only convenient to the setting of detent, and the end face of described projection forms interior limited step simultaneously, thereby simplify the structure.
A preferred version of the present utility model, wherein, described positioning convex is multiple with determining water jacket, is along the circumferential direction uniformly distributed.Particularly, the quantity of described positioning convex and locating slot is 6.Be conducive to like this improve locating effect.
A preferred version of the present utility model, wherein, the top of the outer wall of described bottle is provided with outer limited step, described positioning convex from the bottom of bottle outer wall upwards extend and with described limited step be connected.By positioning convex and outer limited step are linked into an integrated entity, be conducive to improve the intensity of bottle, strengthen sealing effectiveness simultaneously.
A preferred version of the present utility model, wherein, it is outward-dipping skewed that the dual-side of described positioning convex is, and it is outward-dipping skewed that the dual-side of described locating slot is also correspondingly.Like this, in the time being inserted in bottom end cover, the side of described inclination has guide effect, is convenient to being inserted in of bottom end cover.
A preferred version of the present utility model, wherein, described locating slot is arranged on the outer wall of bottle, and described positioning convex is arranged on the inwall of bottom end cover.
The utility model compared with prior art has following beneficial effect:
1, owing to being provided with the locating slot and the positioning convex that extend along the axis direction of bottle between the outer wall at bottle and the inwall of bottom end cover, by the cooperation of locating slot and positioning convex, limit the circumferential movement between bottom end cover and bottle, like this, while connecting upper end cover (or dismounting), only need twist upper end cover, without with the firmly fixing bottom end cover of hand, install and remove all very convenient.
2, after upper end cover is connected with bottom end cover, owing to there being cooperatively interacting of locating slot and positioning convex, whole end cap relatively bottle is made circumferential movement, thereby guarantees can, because of caused by relative motion gap, not improve sealing effectiveness between end cap and bottle.
