Description

A kind of Liquid spraying pump of liquid contents ejection usefulness

Technical field

The utility model relates to a kind of Liquid spraying pump, relates in particular to the Liquid spraying pump of a kind of content for liquid (for example oily liquids etc.) ejection usefulness.

Background technology

Traditional automatic Liquid spraying pump, " die mould vacuum type cosmetics quantitatively spray structure under the shower nozzle " that comprises Korean Patent communique numbering 100525455, from the piston structure that combines with the axis of the piston bottom, all be that switch portion is inserted in wanting on the mouth of the axis of the piston master wall place.Consequently, flow into the switching surface that the interior content pressure of cylinder is opened piston according to content compression piston down force pressure.

But there is following problem in the prior art with structure like this.Though the switch portion of piston can prevent that in the dead of night the area that prevents the leakage sealing surface on content ostium top is too narrow and small, so the switching surface of piston forms a space between sealing surface and the piston switch face when being opened, and occurs the leakage problem easily.

The greasepaint that is applied in human body skin or face is super lubricated refining forming, and the phenomenon of leakage appears in the sealing branch that suction combines by the axis of the piston and piston when starting formation and ejection.And with regard to the situation of liquid cosmetics, if viscosity is lower, the lubricity height, then the phenomenon of leakage can be more serious.

The phenomenon of leakage makes the content leakage remain in the space between container cover and the axis of the piston, and contacting with extraneous air can acidifying or sclerosis, thereby the content that can occur in the container pollutes, and reduces the problems such as pumping function of automatic Liquid spraying pump.

Summary of the invention

The specific embodiment

The utility model will be further described below in conjunction with drawings and Examples.

Fig. 1 shows the structure of preferred embodiment of the Liquid spraying pump of liquid contents of the present utility model ejection usefulness.See also Fig. 1, Liquid spraying pump mainly constitutes with lower member: have the shower nozzle 30 of content squit hole 31, shower nozzle 30 is also offered cylindrical portion discrepancy space 100; Lid 20 with cylindrical portion 21, cylindrical portion 21 are inserted in the cylindrical portion discrepancy space 100 of shower nozzle 30; Cylinder 40 with negative pressure trough, the bottom of cylinder 40 have inflow entrance 41 of content, and inflow entrance 41 places are provided with switching ball 42 at content; Be arranged on the axis of the piston 50 of the inside of covering 20 cylindrical portion 21, the top of the axis of the piston 50 is connected with shower nozzle 30, inner hollow is to form content ejection passage 51, the bottom of the axis of the piston 50 is piston holder faces 52 of an inclination, piston holder face 52 tops form the piston installation and want mouth 53, piston is installed and is wanted mouthful 53 places to be formed with the content secondary inflow entrance 54 that two symmetries are offered again, and four content flow channels 230 are equally spaced offered in the side of piston holder face 52; Piston 70 is installed on the piston installation and wants mouth 53; Return spring 60, one ends connect the bottom of the axis of the piston 50, and the other end connects switching ball 42.

Please be simultaneously referring to Fig. 4, the Liquid spraying pump characteristic of present embodiment is: piston 70 is by being that to be that material is refining form in the rubber agent extremely strong with durability, elasticity and recuperability, that particle density is high, its surface brightness is very high, and compression function, sealing function and durability are all very outstanding.Piston 70 has top compressed pipe 71 and bottom compressed pipe 72, and the piston inner face forms the fixing outstanding groove 300 of the piston that is positioned at the top and is positioned at the outstanding groove 310 of content switch of below, and between forms the face 320 of nipping.Accordingly, want mouthful 53 places in the piston installation, offer the fixing mouth 200 of wanting of piston in the top of content secondary inflow entrance 54, the fixing outstanding groove 300 of the piston of piston 70 is inserted in firmly that piston is fixing wants in mouthfuls 200 outstanding end face 300 ' of content sealing that fixing outstanding groove 300 bottoms of piston form and a fixing content sealing surface 210 common sealings 301 that are "  " font that form of wanting mouthful 200 bottoms to form of piston.Want mouthful 53 places in the piston installation, content switching surface 220 is offered in below in content secondary inflow entrance 54, the outstanding groove 310 of the content switch of piston 70 places on the content switching surface 220, and the outstanding groove 310 of content switch is upwards tortuous to open content secondary inflow entrance 54 when being under pressure.

See also Fig. 1 and Fig. 2, when piston 70 is in "off" state, because the elastic force of return spring 60, make shower nozzle 30, the axis of the piston 50 and piston 70 be the rising state, under the state that shower nozzle 30 rises, form and cover the come in and go out state in space 100 of cylindrical portion that 20 cylindrical portion 21 is inserted in shower nozzle 30, can prevent the foreign matter inflow.

See also Fig. 1 and Fig. 3, spray content if desired, then only need to press lower nozzle 30, pressing down of the axis of the piston 50 and piston 70 makes generation pressure in the cylinder 40, switching ball 42 will be sealed inflow entrance 41 of content thus, and the pressure of the content in the cylinder acts on cylinder upper, and pressure is applied to the outstanding groove 310 of content switch that basifacial forms in the piston 70, the upwards expansion of outstanding groove 310, and produce the space between the content switching surface 220.Content flow into content secondary inflow entrance 54 by this space, and the content squit hole 31 by content ejection passage 51 and shower nozzle 30 outwards sprays then.

By the content flow channel 230 on the piston holder face 52, content will evenly flow into so that apply the pressure stability of the content of piston 70 bottoms.The top compressed pipe 71 of piston 70 and bottom compressed pipe 72 relate to the pressure stability of cylinder 40 inwalls, improve compression function.Content flow channel 230 can avoid bottom compressed pipe 72 inner faces and inclination piston holder face 52 stickup and cause losing the phenomenon of piston function.

When the face of nipping 320 that forms between the fixing outstanding groove 300 of the piston that piston 70 inner faces form and the outstanding groove 310 of content switch makes that the outstanding groove 310 of content switch is subjected to content pressure easily to the upper direction complications, unlatching content secondary inflow entrance 54.

The fixing outstanding groove 300 of the piston that piston 70 inner faces form firmly is inserted in the piston installation of the axis of the piston 50 and wants the fixing mouth 200 of wanting of mouthful 53 formed pistons, makes piston 70 can not break away from the axis of the piston 50 in frequent lifting action.The enlarged meeting of sealing 301 improves sealing property greatly, thoroughly prevents the phenomenon of leakage of content.

Inventive point of the present utility model is that piston 70 and corresponding piston are installed and wants mouthfuls 53 design.The foregoing description provides to those of ordinary skills and realizes or use of the present utility model; those of ordinary skills can be under the situation that does not break away from invention thought of the present utility model; the foregoing description is made various modifications or variation; thereby protection domain of the present utility model do not limit by the foregoing description, and should be the maximum magnitude that meets the inventive features that claims mention.
