Abstract

The utility model relates to a novel daily toiletry which overcomes the defects that general miniature spray jet provides thick mist granules with water droplets, and the consumption of primary materials is big. The miniature spray jet of the utility model has the advantages of reasonable structure, light weight and good tightness and comprises a snap head, a gross cap, a valve head, a cylinder block, a spray jet, a piston and springs. All the components are made of polypropylene, and high and low polyethylene except the springs. Besides, the utility model is characterized in that mist granules are thin and are distributed uniformly.

Description

Miniature spray jet

The utility model is a kind of new micro fog-spray nozzle, belongs to daily cosmetic product.

Domestic commercially available mini spray head generally only adopts the cylinder type valve, be difficult for sealing, and fogging degree is not good, and droplet slightly or in the mist is mingled with little water droplet, and therefore a discharge rate (cosmetics) is more, wastes bigger; Or by spray space soup skewness, desinsection (or sterilization) weak effect, fog-spray nozzle weight is heavier simultaneously, and consumption of raw material is more.

In view of the above problems, the purpose of this utility model is to provide a kind of atomizing fully, and the lighter new micro fog-spray nozzle of weight.

The method of solution task is to adopt valve head and valve head seat and piston and cylinder body tight fit, and shower nozzle is offered three helicla flutes by certain angle simultaneously, makes liquid under high pressure, and rotation sprays and nebulizes at a high speed.

The utility model has the advantages that: owing to closely cooperating of valve head and valve head seat and piston and cylinder body, solved sealing problem, three helicla flutes on the shower nozzle and the angled even expansion of center line, it is vaporific fully to spray, and be evenly distributed the economized cosmetics.Nut and cylinder body holder join together, have reduced both bonding process.

Overall,, reduced the necessary pellet shot from a slingshot of original technology again and filled out circle, therefore can alleviate about 30% of whole fog-spray nozzle weight, thereby save raw material because the topology layout reasonable volume is little.

For the ease of understanding the utility model, be described further below in conjunction with accompanying drawing:

The mini spray head is pressed head (1), sieve cap (2), valve head (3), cylinder body (4), shower nozzle (5), piston (6) and spring (7) parts formation.Except that spring, other parts are all made by polypropylene and high and low polyethylene.

Shower nozzle (5) is contained in to be pressed on the head (1), and its head has three helicla flutes (11), and inwall has three straight grooves (19) to link with it.Article three, helicla flute designs (see figure 4) by following design: by center, shower nozzle hole (18), appoint standardized center line (diameter) (27), with this center line (27) is benchmark, center, shower nozzle hole (18) is the center, by 35～45 degree spiral trough rims of picture (28), and then with center line (27) with the circle (shower nozzle inwall) intersection point (29) be starting point, swing to shower nozzle hole (18) direction and mark another spiral trough rim (30) by 5～15 °, press certain diameter (than the big several times in aperture) again and draw a roundlet (31), in spiral trough rim (28), (30) and one section radian of inwall enclose that All Ranges all is provided with a shallow groove in a pocket and roundlet (31) circle, all the other two helicla flutes, offer as stated above every 120 °, wherein the helicla flute angle by 45 ° with fall 15 ° of institutes and enclose tiny area setting, spray effect the best.Aperture, shower nozzle hole (18) is 25～30.

Piston (6) top (32) is pressed into the hole of pressing centriciput, the piston center is a passage (34), the following of it corrects to blocking the solid needle upper end (20) of valve head (3), piston relies on external force and spring (7) to do upper and lower motion in cylinder body (4), the piston lower end is one and expands body (33), closely contacts with cylinder body.

The logical down drum of lid is arranged, solid needle of middle insertion on valve head is similar.It can be divided into solid needle (20,24), cross muscle (22) valve head wall (25), step (26), in addition, also has fluid passage---and valve head is towards liquid bath (10) and prevent that piston from choosing the sharp muscle (21) of pendulum.Step (26) divides three grades, and the step that is in valve head wall bottom more is thin more.Valve head cooperates with the valve head seat, the internal diameter that adopts valve head is littler one, two or equate than valve head seat external diameter, elastic reaction by means of plastics, valve head and valve head seat wall are closely cooperated, guarantee that like this valve head is when entangling the valve head seat, can stop that liquid passes in and out between the space that surrounded by cylinder wall (15) and valve head seat (14) and the valve head enclosed space, thereby play sealing function.

Spring places between valve head solid needle lower end (24) and the spring base (13), and its main effect is after the external force cancellation, valve head, piston reset, and finishes the imbibition action.The spring steel wire diameter is 0.5mm, is made by stainless steel.

Mother sieve (2) joins together with cylinder body holder (16), has on the cylinder body holder to substitute to fill out the valve line (17) of circle effect.

Cylinder body (4) is suction socket (12) bottom, in valve head seat (14) and spring base (13) are arranged, other has a cylinder body return-air groove (8), and they are all once injection molded with polypropylene.

To press head (1) when pressing, piston (6) and valve head (3) are simultaneously downwards, when valve head (3) entangles valve head seat (14) and continues to move downward, gas in the cylinder body is discharged, loosen and press head, rely on elastic force, valve head and piston reset, gas is thin in the cylinder body, air pressure reduces, liquid enters cylinder body thereupon in the bottle, finish the imbibition action, reciprocal like this 2～3 times, make solution be full of the cylinder body volume, press once more and press head, valve head (3) still entangles valve head seat (14), at this moment, valve head separates fully with valve head seat (14) enclosed space and cylinder space, and solution can't return in the container and go in the cylinder body, thereby solution produces pressure to cylinder body and piston, continue downwards along with pressing head, pressure constantly raises, when pressure surpasses the compression resistance force of spring (7), spring further is compressed, make valve head (3) separate with piston, solution promptly under high pressure by valve head towards liquid bath (10), piston central passage (34), pour shower nozzle inboard wall groove (19), through three helicla flutes (11), solution produces rotation at a high speed, ejection shower nozzle hole (18), solution rapid expansion and nebulizing.Air is by sieve cap return-air groove (9) in the container, and cylinder body return-air groove (8) supply is so that the container inner and outer air pressure equates.
