The utility model relates to an explosion type spraying pump which has the characteristics of good atomization effect and convenient use, which comprises a spraying nozzle, a main column, a screw cover, a body and a spring. The utility model is characterized in that a guiding spacing wing matched with the main column is arranged on the upper side of the screw cover; the outer edge of an upper opening of the body is fixed at the lower side of the screw cover in order to limit the range that the main column slides up and down; a glass ball is arranged at the bottom of an inner cavity of the body, and forms a one-way valve with a liquid inlet at the bottom of the inner cavity; a valve core on the top part of a piston core is butted on a liquid outlet of the main column; a big piston is arranged on the upper part of the piston core, and forms a back pushing cavity with an inner cavity of the main column; a small piston is arranged on the lower part of the piston core, and forms a pressure cavity with the inner cavity of the body; a passage which is used for communicating the back pushing cavity and the pressure cavity is arranged in the piston core, and the spring is arranged between the piston core and the bottom of the inner cavity of the body.

Description

The blasting type atomizing pump

Technical field

The utility model relates to a kind of atomizing pump, particularly a kind of blasting type atomizing pump.

Background technique

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 sprayer " by name; This " mouth cleaning solution sprayer " is that suction pipe and nozzle are set on liquid storage bottle, it is characterized in that pressure-raising pump of installing on the liquid storage bottle, is provided with valve body, spring and valve in the pump housing, and valve body becomes the 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 sprayer " 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

The purpose of this utility model be for solve existing sprayer exist atomizing effect poor, can not guarantee the problem of each atomizing effect that sprays, and provide a kind of atomizing effect good, easy to use blasting type atomizing pump.

Technological scheme:

The purpose of this utility model is achieved in that a kind of blasting type atomizing pump, comprises nozzle, principal post, blind nut, body and spring; It is characterized in that the blind nut upside is provided with the guide and limit wing that matches with principal post, the upper shed outer rim of body is fixed on the blind nut downside to limit the scope that principal post slides up and down, the liquid entering hole that glass ball and intracavity bottom are placed in the chamber body bottom constitutes one-way valve, the spool at piston core top withstands the liquid outlet of principal post, the inner chamber formation that piston core top is provided with big piston and principal post pushes back the chamber, the inner chamber that the piston core bottom is provided with small piston and body constitutes pressure chamber, be provided with the passage that connection pushes back chamber and pressure chamber in the piston core, between piston core and the chamber body bottom spring be set.Under the normality, spool at the effect lower piston core top of spring force withstands the liquid outlet of principal post, the pressure chamber internal memory has liquid to be atomized, with hand with principal post when pressing down, principal post drives large and small piston DL synchronization increases pressure chamber and the pressure that pushes back in the chamber, because the cross section of big piston is greater than the cross section of small piston, so, when the pressure in pushing back the chamber increases to a certain degree, big piston drives piston core and moves down with respect to principal post, spool separates with liquid outlet on the principal post, pressure chamber and push back the liquid chamber in through liquid outlet and nozzle and atomize.Certainly, if it is less to depress the stroke of principal post, then push back in the chamber underpressure so that spool separate with liquid outlet, atomizing pump can not be sprayed, still, in case the descending stroke of principal post is enough, then because of huge enough pressure arranged, so atomizing effect is good through the liquid of nozzle ejection.

Described blasting type atomizing pump is characterized in that described piston core middle part is provided with seal ring, and body top is provided with upper and lower two pores, and two pores are between the seal ring and small piston of described piston core during normality.Common pore generally is opened in body and arrives between the blind nut downside at small piston, with the pressure inside and outside the equilibration flask, prevents that bottle from shrinking because of negative pressure, and when the shortcoming of this structure was the bottle inversion, liquid was promptly through this pore outflow in the bottle; And its effect of two pores is set is the product that prevents to be equipped with atomizing pump (as hair jelly etc.) at this place, the careless inversion in transportation process and cause the problem of leakage, certainly, the position of upper and lower pore should be designed by following requirement as far as possible: upward pore should be tried one's best and then should be tried one's best near small piston near the following pore of seal ring.

Beneficial effect:

Owing to adopted technological scheme described in the utility model, the ejection liquid before ejection through precompressed, if pressure is not enough, spool can not separate with the liquid outlet on the principal post, liquid can not spray, have only when the pressure in the pressure chamber is enough big spool just to separate,, guaranteed that each injection all has atomizing effect preferably so the jet velocity of the liquid of ejection is just high with liquid outlet on the principal post.
