Abstract

The utility model relates to a spray pump, which comprises a nozzle, a press head, a principal post, a locking closure, a thread, a secondary post, a body and a spring; and the spray pump is characterized in that the secondary post is positioned below the principal post which the middle is provided with a through hole and the lower part has a piston; an end face of the top of the secondary post just faces a lower end face of the through hole which is arranged at the middle of the principal post, and the lower side of the secondary post has a ring water insolating sphere; the lower part of the body upwards extends a pipe body, a lower opening of the pipe body is communicated with a bottle body, an upper opening of the pipe body faces the water insolating sphere of the secondary post, and the outside diameter of the pipe body is glidingly matched with the water insolating sphere.

Description

Atomizing pump

Technical field:

This utility model relates to a kind of atomizing pump, particularly a kind of pressure atomization pump that does not have check valve.

Background technology:

Notification number disclosed be CN2357747Y, the patent No. and be 98251121.3 in the Chinese patent on January 12nd, 2000 bulletin, the patent application of " mouth cleaning solution aerosol apparatus " by name; This " mouth cleaning solution aerosol apparatus " is that suction pipe and nozzle are set on liquid containing bottle, it is characterized in that pressure-raising pump of installing on the liquid containing bottle, is provided with valve body, spring and valve in the pump housing, and valve body becomes the air-tightness link joint with pump housing inner chamber, constitutes piston; Valve body moves up and down in the pump housing under the effect of hand and spring repeatedly, liquid in the bottle is sucked suction pipe, and extrude atomisation from nozzle.The shortcoming of this " mouth cleaning solution aerosol apparatus " is that atomizing effect is poor; As in the strength of hand also can be with bottle very little time liquid ejection, but the liquid of ejection can not atomize because of jet velocity is low, ejection can only be water column; As guaranteeing each atomizing effect that sprays, just necessary enough big power and the speed used must be fast, but the strength of its hand is uncontrollable, so atomizing effect is difficult to control.

Certainly, the purposes of atomizing pump described in the utility model is not limited to be used in the atomizing of mouth cleaning solution, also can be used on the cosmetics such as hair jelly.

Summary of the invention:

Technical problem: existing aerosol apparatus, liquid ejection in the strength of hand also can be with bottle very little time the, but the liquid of ejection can not atomize because of jet velocity is low, ejection can only be water column; As guaranteeing each atomizing effect that sprays, just necessary enough big power and the speed used must be fast, but the strength of its hand is uncontrollable, so atomizing effect is difficult to control.So there is the problem that atomizing effect is poor, can not guarantee each atomizing effect that sprays in existing aerosol apparatus.

This utility model will solve existing aerosol apparatus and have the problem that atomizing effect is poor, can not guarantee each atomizing effect that sprays.

Technical scheme:

The purpose of this utility model is achieved in that a kind of atomizing pump, comprises nozzle, head, principal post, locking closure, thread, subpost, body and spring; It is characterized in that central authorities are provided with the principal post below placement subpost of through hole and bottom band piston body; Subpost upside end face is over against the lower surface of principal post center through hole, and the subpost downside is an annular water proof circle; The body bottom protrudes upward body, and the body under shed communicates with bottle, and the body upper shed is over against the water proof circle of subpost, and the internal diameter of the external diameter of body and water proof circle is slidingly matched.

Operation principle: when pressing head, piston body on the principal post promotes subpost drive water proof circle and moves to the body direction, at this moment because of being subjected to the effect of spring force, subpost make the subpost upside be close to the mesopore of principal post, at the initial stage that principal post and subpost move downward, intrinsic partially liq part is pushed back in the bottle, air partly is forced out outside the bottle in the bottle, intrinsic liquid temporarily can not spray, after head is depressed into the water proof circle and body contacts, intrinsic liquid is separated with the intravital liquid of bottle, intrinsic liquid is sealed, continue to depress head, intrinsic pressure sharply increases, when power that the suffered downward pressure of subpost makes progress greater than spring, subpost moves down, subpost upside end face is separated with the lower surface of principal post center through hole, intrinsic liquid sprays rapidly through nozzle from the through hole of principal post central authorities, at this moment Pen Chu liquid before ejection through precompressed, if pressure is not enough, then subpost can not separate with principal post, and liquid can not spray, so in a single day subpost separates with principal post, the jet velocity of the liquid of ejection is just high, and atomizing effect is all right; In case after unclamping the hands of pushing head, subpost at first moves upward under the effect of spring force, blocks the through hole of principal post central authorities, promotes principal post then and moves upward, make to produce negative pressure in the body with in the liquid suction body in the bottle, to prepare the usefulness of injection next time.

Beneficial effect:

Owing to adopted technical scheme described in the utility model, the ejection liquid before ejection through precompressed, if pressure is not enough, then subpost can not separate with principal post, liquid can not spray, so in a single day subpost separates with principal post, the jet velocity of the liquid of ejection is just high, has guaranteed that each injection all has atomizing effect preferably.

The specific embodiment:

Fig. 1 is the internal structure sketch map of a specific embodiment of atomizing pump described in the utility model.

Fig. 1 is the sketch map of atomizing pump when being in waiting state, and as can be seen from Fig. 1, described atomizing pump comprises nozzle 3, head 2, principal post 4, locking closure 5, thread 6, subpost 8, body 10 and spring 11; Principal post 4 belows are provided with piston body 41, and the central authorities of principal post 4 are provided with through hole 42, and through hole 42 upper ends communicate with nozzle 3; Head 2 is covered with dust cap 1; Subpost 8 is placed in principal post 4 belows; Subpost upside end face 81 keeps apart body 10 inner chambers and nozzle 3 over against the lower surface of principal post 4 center through hole 42, and subpost 8 downsides are fixed with annular water proof circle 9; Body 10 bottoms protrude upward body 101, and body 101 under sheds communicate with bottle by suction pipe 12, and body 101 upper sheds are over against water proof circle 9, and the internal diameter of the external diameter of body 101 and water proof circle 9 is slidingly matched; The effect of pad 7 is to make between thread 6 and the bottle effectively to seal.

Fig. 2 is head 2 be pressed back subpost upside end face 81 and state diagram after the through hole 42 of principal post 4 separates certain distance among Fig. 1.
