Abstract
The utility model relates to a sucker structure for the sprayer, which comprises a piston (7), a sucker sleeve (9), a big circle (13), and a sucker (14); wherein the sucker sleeve (9) is inserted in the big circle (13) and the upper end of the sucker sleeve (9) is spliced with the lower end of the piston (7), while the lower end of the sucker sleeve (9) is spliced with the upper end of the sucker (14). The utility model is characterized in that the lower end of the sucker sleeve (9) extends out of the big circle (13), which ensures a space between the sucker (14) and the big circle (13). Compared with the prior art, the utility model has the advantages that: when the sucker sleeve is prolonged and extended out of the big circle, the filling is undergone by clamping the sucker sleeve through the automatic machine fixture; due to the sucker sleeve with more rigidity than the sucker, the inclination caused by the clamping of the flexible sucker is prevented, so the working efficiency for the filling is improved.
Description
Technical field
The utility model relates to a kind of sprayer, relates in particular to a kind of sprayer suction-pipe structure.
Background technology
Existing sprayer mainly comprises housing, great circle, head cap part, spanner mechanism, piston portion and tube segment, spanner is pulled, piston portion and tube segment move up in the housing inner chamber, air pressure raises in the inner chamber, unclamps spanner, produces negative pressure in the inner chamber, liquid upwards passes through suction pipe under suction function, enter piston, pull spanner once more, from the beginning cap portion ejection of liquid.Specifically can disclose a kind of " Improved hand-clasping type atomizer " (publication number: CN2719412Y) with reference to Chinese utility model patent: ZL2004200813.9.X.The tube segment of above-mentioned patent exists anti-tripping power poor, caducous deficiency.
For this reason, Chinese invention patent application: CN200610052124.X, disclosed a kind of " hand fastening type sprayer structure " (publication number: CN1895791A), this application comprises square toes head cap, main body, case, big spring, piston, suction cover, stifle, suction pipe of sprayer etc., main points are that the original structure piston details is divided into two, piston and suction cover.One section internal diameter of one section external diameter and suction cover of piston is inlayed and is connected; Also inlay for one section of the extension of suction cover and suction pipe and be connected.Can see that from the accompanying drawing of this application suction cover is positioned at great circle, and suction pipe is drawn from the great circle bottom directly, there is following deficiency in this kind design; When the automation can, utilize the suction pipe of the clamp clamps sprayer of automatic machinery, itself has flexibility suction pipe, and behind the clamp clamps suction pipe, tilt phenomenon appears in sprayer easily, like this, will influence can efficient.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of sprayer suction-pipe structure at the above-mentioned state of the art, suction cover stretches out great circle in this structure, there are certain spacing in suction pipe and great circle thus, so that automatic machinery clamp clamps suction cover part is finished can.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this sprayer suction-pipe structure, comprise piston, suction cover, great circle and suction pipe, described suction cover is arranged in the great circle, and its upper end is inlayed with the bottom of piston and is connected, the bottom is inlayed with the upper end of suction pipe and is connected, it is characterized in that described suction cover bottom stretches out outside the great circle, and make suction pipe and great circle form an intersegmental distance.
As improvement, the upper end internal diameter of described suction cover is greater than the bottom internal diameter.
As improvement, one section external diameter of described piston lower end links to each other with one section internal diameter of suction cover upper end, and one section external diameter of described suction pipe upper end links to each other with one section internal diameter of suction cover bottom.
As preferably, the spacing that described suction pipe and great circle form is 20mm at least.Suction cover is injection mo(u)lding, can determine the upper limit of this spacing according to sprayer size practical situations.
Compared with prior art, advantage of the present utility model is: after great circle is stretched out in the suction cover prolongation, make automatic machinery clamp clamps suction cover part just can carry out can, because the hardness of suction cover is greater than suction pipe, so avoided because of clamping the tilt phenomenon that soft suction pipe occurs, thereby improved the operating efficiency of can, simple and practical.
Description of drawings
Fig. 1 is the cross-sectional view of embodiment.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Embodiment is with reference to figure 1.
Sprayer in the present embodiment comprises that head cap 1, rubber block 3, divide water jacket 2, main body 4, outer cover 5, spanner 15, spring 6, stifle 10, great circle 13, suction pipe 14 and suction cover 9.
Piston portion is made up of piston 7 and suction cover 9, is placed with bead 8 in the endoporus of piston 7,8 non-return valve function of bead, and driving lower piston 7 at spanner 15 can move reciprocatingly in main body 4 inner chambers, and spring 6 places main body 4 inner chambers to play return piston 6 effects.
Stifle 10 is inserted in main body 4, and great circle 13 is enclosed between stifle 10 and the main body 4, can be free movable.Insert sealing ring 11 in stifle 10 endoporus, sealing ring 11 endoporus have a circular arc type boss and suction cover 9 interference fit, keep sealing to prevent that liquid oozes out under the product inversion state in bottle, because sealing ring self elasticity, suction cover 9 feel when sliding up and down is pleasant.
Suction cover 9 is arranged in the great circle 13, and its upper end inlays with piston 7 bottoms and be connected, and the bottom is inlayed with suction pipe 14 upper ends and is connected, and it is outer and makes suction pipe 14 and great circle 13 form an intersegmental distance that great circle 13 is stretched out in suction cover 9 bottoms.Spacing is at least 20mm, can determine the upper limit of this spacing according to sprayer size practical situations.
The upper end internal diameter of suction cover 9 is greater than the bottom internal diameter.One section external diameter of piston 7 bottoms links to each other with one section internal diameter of suction cover 9 upper ends.One section external diameter of suction pipe 14 upper ends links to each other with one section internal diameter of suction cover 9 bottoms.
Operation principle: when pulling spanner 15, drive in piston 7 and suction cover 10 main bodys 4 inner chambers and move up, this moment spring 6 be compressed, in main body 4 inner chambers air pressure rise to the highest, when unclamping spanner 15, piston 7 and suction cover 10 are reset to original state under spring 6 effects, air pressure is reduced to minimumly in main body 4 inner chambers, produces negative pressure, in the bottle liquid under suction function upwards by suction pipe 14, wash glass marble 8 open, enter in main body 4 inner chambers.Pull spanner 15 once more, main body 4 inner chamber liquid are washed open under the extruding force effect and are blocked 3, enter in the branch water jacket 2, from head cap 1 apopore ejection outside, it is vaporific that the head cap endoporus has spin slot that liquid is formed. upwards be squeezed to main body 4 cavity volume hour at piston 7 and suction cover 9, air discharge duct on the suction cover 9 is communicated with extraneous, and ambient atmos enters in the bottle, reduces to replenish owing to continuous drawing liquid causes the bottle internal gas pressure.
