Abstract

A sprayer includes a shell (1) with a neck (2), a spray head (6) which is fixed on the neck through thread or in other ways and a suction tube (7) which extends from a liquid inlet of the sprayer head to the shell to suck the liquid which is to be ejected. The sprayer is characterized in that the shell is equipped with a top-down convergent inner liner (3) in which the liquid (5) to be ejected is contained. The suction tube (7) extends all the way down to the bottom of the inner liner (4) so that all the liquid can be sprayed out without any remnant. The sprayer is made from nonpolar materials so that the sprayer can be used as an ideal spraying tool for adhesives, especially alpha cyanoacrylate.

Description

A kind of sprayer

Technical field

The utility model relates to a kind of sprayer, especially a kind of sprayer of low dose.

Background technology

Traditional sprayer comprises the housing with a neck that is used for storing the liquid that will spray, is connected fog-spray nozzle on the described neck with screw thread or other modes, and extends in the housing in order to draw the suction pipe of the liquid that will spray from the inside of fog-spray nozzle inlet.This sprayer can also can be with propellant, for example fluorine Lyons without propellant.

This traditional sprayer can not eject the liquid in the housing usually fully, and always has residual.Especially all the more so when housing is tilted.This be because: especially for the sprayer that is suitable for standing when not using, the inner surface of its housing bottom is convex surface, plane, or the very big concave surface of radius of curvature, so residual liquid can form thin layer and difficult sucked by suction pipe on housing bottom; When sprayer tilts, residual liquid will focus on certain edge of housing bottom and not in position, suction pipe lower end, liquid can not be sucked by suction pipe.

For the sprayer that uses propellant such as fluorine Lyons (referring to the applicant's patent of invention 92109639: a kind of preparation method of aerosol type medical adhesive), though under handstand state, can barely spray fully, but in other positions just can not, and following shortcoming is arranged: (1) fluorine Lyons smell is big; Be to guarantee that the pressure in the housing must use sealing gasket when (2) using propellant, and the material of sealing gasket often easily with the liquid that will spray, for example a-cyanoacrylate class adhesive reaction destroys the stability of glue, and stops up jet; (3) atmosphere is destroyed in fluorine Lyons, has been under an embargo in the world as propellant, and domestic also very fast meeting is by total ban.

Because above-mentioned existing sprayer can not spray the liquid of interior storage fully usually, just can not be used for the injection of low dose of liquid certainly.And low dose of liquid to spray be necessary under many circumstances, for example use of a-cyanoacrylate class adhesive in medical treatment only need be used 0.1 milliliter or still less sometimes.This adhesive is widely adopted in industry, family expenses, medical treatment because its curing rate is fast, adhesive strength is big.But this series products does not have suitable gluing instrument, often causes failing with glue.Especially at medical field, mainly show following two aspects: the one, the doctor often has little time operation (the very fast curing of glue loses use value); The 2nd, the control of glue consumption (do not have suitable gluing instrument, cause trickling).These two problems had both hindered use, had caused waste again.The applicant's foregoing invention patent 92109639 has solved above-mentioned two problems in the mode of spraying gluing, but as mentioned above, because sealing device to the chemical instability of the liquid of adorning and the blockage problem of jet in the housing, often causes the liquid in the housing to be wasted because of rotten maybe can not the ejection greatly.Therefore, preferably use low dose of sprayer, when using above-mentioned adhesive, needs from permanent tank, in this sprayer, inject required dosage, for example tens milliliters to several milliliters, until 0.1ml or still less, spray by this sprayer then and use, and do not allow adhesive in sprayer, store for a long time.

Summary of the invention

The purpose of this utility model provides a kind of sprayer, is provided with one and is the inner bag of collapsed shape gradually from top to bottom in the housing of above-mentioned sprayer, solving the incomplete problem of above-mentioned injection, and then solves the injection problem of low dose of liquid.Thereby for adhesive especially a-cyanoacrylate is that adhesive provides a kind of desirable Spray painting tool.

For this reason, the utility model proposes a kind of sprayer, it comprises housing with neck, is connected fog-spray nozzle on the described neck with screw thread or other modes, and extend in the housing in order to draw the suction pipe of the liquid that will spray from the inside of fog-spray nozzle inlet, it is characterized in that, an inner bag is set in described housing, this inner bag is the shape of shrinking gradually from top to bottom, the liquid that sprays is contained in this inner bag, and described suction pipe reaches this inner bag bottom always.

Like this; because this inner bag shrinks from top to bottom; its bottom area is very little; therefore can guarantee that sprayer can both spray liquid wherein smoothly the arbitrarily angled of 30-90 degree; and spray complete and noresidue; therefore can not use propellant such as fluorine Lyons, not have smell, help environmental protection again.Therefore and because described housing still keeps, whole sprayer still is suitable for standing (when housing when being flat) and can tumble easily because of traverse, perhaps still has the function that shape or other character determined by this housing.

Because without propellant, do not exist in the problem that seals under the bigger pressure, therefore this sprayer integral body comprises that fog-spray nozzle and pump installation wherein all can be with non-polar material medical poisonless polypropylene for example, polystyrene, manufacturings such as polyethylene, thereby can be used for spraying present a-cyanoacrylate system and (comprise ethyl ester, propyl ester, positive butyl ester, isobutyl ester, n-octyl, alkoxy ester etc.) adhesive, and do not have stability and a blocking problem of destroying glue because of sealing gasket dissolving, make glue can become aqueous ejection, evenly fast, do not trickle, do not block up.Thereby this sprayer can be brought into play the premium properties of such glue to greatest extent as the desirable Spray painting tool of described adhesive.As the gluing instrument, can freely control glue consumption with this sprayer, spraying rapidly.And, because can be in the arbitrarily angled injection of 30-90 degree, therefore easy and simple to handle, be particularly suited for the doctor and use.
