Convenient, the first snap fit tabs 113 are installed to after the first neck 124, and the second snap fit tabs 123 are located at the first snap fit tabs 113
Away from bottleneck side, now lid 120 and bottle 110 can be carried out in radial directions it is spacing, when lid 120 is by remote
From bottleneck radial forces when, the first snap fit tabs 113 are against the second snap fit tabs 123, so as to prevent lid 120 from taking off
From improving the assembly reliability of lid 120 and bottle 110；Offer what is radially extended in the second snap fit tabs 123 simultaneously
Locating slot 125, connecting portion 112 also includes the positioning bar 114 being arranged on the outer wall of bottle 110, when bottle 110 is pacified with lid 120
It is attached to behind position, positioning bar 114 is placed in the locating slot 125, the now cooperation of positioning bar 114 and locating slot 125 can be
Lid 120 and bottle 110 are carried out in circumferential direction it is spacing, when lid 120 is by less circumferential active force, positioning bar
114 against locating slot 125 cell wall, so as to prevent lid 120 from rotating, the assembling for improving lid 120 and bottle 110 can
By property.
When needing dismounting lid 120 and the replacing filter element of bottle 110, it is only necessary to first apply larger circumferential active force,
Second snap fit tabs 123 are rotated to the gap between two the first snap fit tabs 113 of alignment, then apply the footpath away from bottleneck
To active force, you can lid 120 and bottle 110 are taken apart., can also be in order to which lid 120 and bottle 110 can be dismantled smoothly
Certain guide frame (such as guiding surface) is set on positioning bar 114 and locating slot 125.
In order to reach better seal effect, and connection for the ring part 122 of connecting portion 112 and second provides bigger sky
Between, referring to Fig. 4, in the present embodiment, the diameter of the second ring part 122 of the cover rim is more than the first annular portion 121；
The first annular portion 121 is connected with second ring part 122.Now the diameter of bottleneck is just in first annular portion 121
Coordinate, and to be then the first snap fit tabs 113 and the second snap fit tabs 123 carry for gap between the second ring part 122 and bottle 110
For space, so, sealing property and switching performance are more independent, are independent of each other, and link position slight loosen occurs and is not easy to lead
The problem of leak of cause.
Lid 120 excessively rotates during in order to avoid installing, referring to Fig. 3, in the present embodiment, second snap fit tabs
123 one end bends towards the first annular portion 121 and is connected with the first annular portion 121.When the first snap fit tabs
113 relative to the second snap fit tabs 123 rotate when, turn to one be connected against the second snap fit tabs 123 with first annular portion 121
End can not rotate again, so as to reach locating effect, it is to avoid lid 120 rotates excessively and loosened, and improve bottle 110 and lid
The assembly reliability of body 120.
Further referring to Fig. 3, a circle is circumferentially convexly equipped with the present embodiment, on the outer wall of the bottle 110 spacing
Muscle 115, the limit rib 115 is abutted with the cover rim of the lid 120, to carry out spacing, the limit to the lid 120
Position muscle 115 limits the second neck 116 with first snap fit tabs 113；Second snap fit tabs 123 are placed in described
In two draw-in groove 116.By setting limit rib 115, the alignment function of lid 120 in radial directions can be simplified, facilitate lid
120 install with the cooperation of bottle 110.Lid 120 excessively rotates during in order to avoid installing, further referring to Fig. 3, in this implementation
In example, one end of first snap fit tabs 113 bends towards the limit rib 115 and is connected with the limit rib 115.When
Second snap fit tabs 123 relative to the first snap fit tabs 113 rotate when, turn to against the first snap fit tabs 113 and the second annular
One end that portion 122 is connected is to rotate again, so as to reach locating effect, it is to avoid lid 120 rotates excessively and loosened, and carries
The assembly reliability of high bottle 110 and lid 120.
User determines whether to be installed in place for convenience, referring to Fig. 1, in the present embodiment, at first neck 124
Offer the peep hole 126 for appearing first snap fit tabs 113.Whether appear the first engaging in peep hole 126 by observing
Projection 113 may know that whether the first snap fit tabs 113 are installed into the first neck 124, in this way, user can intuitively sentence
Disconnected assembling situation, timely self-inspection, correction, so as to improve the assembly reliability of bottle 110 and lid 120.
