Abstract
The invention relates to a multi-hybrid type sprayed liquid atomization head. The multi-hybrid type sprayed liquid atomization head mainly comprises an air cap, a connecting body, a limiting check ring, an air inlet interface, a liquid inlet interface and a core pipe. High-pressure air enters an inner air injection channel and an outer air injection channel respectively after entering a gas buffer chamber; liquid is initially atomized in a cavity after flowing outer of a liquid flow channel; and under the action of pressure, the liquid is sprayed out of an air injection hole after being initially atomized, is mixed with the high-pressure air sprayed out of an outer air injection hole again outside a sprayer and is atomized for a second time. The ratio of the area of a gas inlet of the inner air injection channel (14) to the area of an inlet (6) of the outer air injection channel is adjusted by adjusting the position of the core pipe to fulfill the aim of adjusting the air pressure ratio of two gas channels, so that the optimal atomization effect can be achieved after the position of the core pipe is appropriately adjusted by a user. The multi-hybrid type sprayed liquid atomization head has the advantages of simple structure, convenience in operation, high atomization effect adjustability and good atomization effect.
Description
Technical field
The present invention relates to a kind of polyhybird formula hydrojet atomising head, is a kind of personal protection mask chemistry droplet performance devices.
Background technology
The test of chemistry droplet barrier propterty is used for the detection of mask chemistry droplet barrier propterty.Atomizing hydrojet through to analogue means is tested, and the sealing property of test mask enters in the mask after then test fluid atomizes as if poor sealing and test paper reacts, and makes it variable color.Therefore the fogging degree of test fluid directly affects precision of test result; And existing atomizer all is the shower nozzle of internal-mixing and two kinds of single hybrid modes of exterior mixing; The adjusting of fogging degree also has only through regulating air inlet air pressure or feed liquor flow dual mode; Can not handle the liquid that does not atomize fully, exist the incomplete problem of atomizing.
Therefore, design a kind of fogging degree high atomization shower nozzle, the atomization of liquid demand that satisfies high request just seems very crucial.
Summary of the invention
The objective of the invention is to the problem that exists to prior art, the polyhybird formula hydrojet atomising head that a kind of convenience is provided, can finely tune to fogging degree.This apparatus structure is simple, and is easy to operate, can guarantee the demand of mask chemistry droplet barrier propterty test.
For achieving the above object, the present invention adopts following technical proposals:
A kind of polyhybird formula hydrojet atomising head comprises air cap, connection body, spacing back-up ring, intake interface, feed liquor interface, core pipe, adjustment handle.It is characterized in that: said air cap is fixedly connected through screw thread with being connected body, and 4 outer puff prots and a nozzle are arranged on the air cap, has 2 outer jet inlet channels on the said connection body left step; It is outside that said spacing back-up ring is fixed in the core pipe; Said core pipe outside with is connected body and passes through the screw thread fixed connection; In the middle of the core pipe is fluid course, and this fluid course is stepped, and core pipe left end has jet gas passage in two; The air inlet of interior puff prot gas passage is a strip; Gap between core pipe front end outer wall and the air cap inwall is as far as possible little, can form the cavity of a relative closure with air cap, core pipe middle part be connected gas buffer chamber of body formation; Core pipe front end, air cap are inner and be connected body front end three and form an outer jet channel gas buffer chamber; Said adjustment handle is installed in the low order end of core pipe and connects described fluid course through being threaded, said feed liquor joint weld is fixed on the right-hand member of core pipe, and said intake interface is upward connected said gas buffer chamber in the middle part of being fixed on through being threaded and connecting body.
The above-mentioned gas passage has four edges and circumferentially is uniformly distributed with, and these four gas passage outlets are claimed circular, are uniformly distributed with in the nozzle periphery.
The present invention compared with prior art, have following conspicuous outstanding advantage and marked improvement: the present invention is simple and reasonable for structure; The present invention can make liquid in cavity, carry out the preliminary atomizing of internal-mixing, then in the shower nozzle exit liquid is carried out the exterior mixing secondary-atomizing, and the present invention can realize the trace adjusting of fogging degree through the position of regulating the core pipe; Thereby reach best atomizing effect.

The specific embodiment
A preferred embodiment of the present invention accompanying drawings is following:
Embodiment one: referring to Fig. 1.This polyhybird formula hydrojet atomising head comprises air cap, connection body, spacing back-up ring, intake interface, feed liquor interface, core pipe, adjustment handle.Said air cap (1) be connected body (7) and be fixedly connected through screw thread; 4 outer puff prots (3) and a nozzle (2) are arranged on the air cap (1); Have 2 exterior mixing station inlet channels (6) on said connection body (7) interior step, said core pipe (8) is outside to be fixedly connected through screw thread with being connected body (7), is fluid course (11) in the middle of the core pipe (8); This fluid course (11) is stepped, and core pipe (8) left end has jet gas passage (14) in two; Fit clearance between core pipe (8) front end outer wall and air cap (1) inwall is as far as possible little, can and air cap (1) form the cavity (15) of a relative closure; Core pipe (8) middle part be connected body (a 7) formation gas buffer chamber (13); Core pipe (8) leading portion, air cap (1) are inner and be connected body (7) leading portion three and form an outer jet channel gas buffer chamber (4); Said spacing back-up ring (5) is fixed in the anterior convex shoulder of core pipe (8) place; The position of installing need guarantee when core pipe (8) during in the limit on the left position; Need leave certain distance between spacing back-up ring (5) and the air cap (1), when core pipe (8) is adjusted to the limit on the right-right-hand limit position, can guarantee that cavity (15) is not communicated with outer gas passage gas buffer chamber (4); Said feed liquor interface (9) is fixed on the right-hand member of core pipe (8) and connects said fluid course (11) through being threaded, said intake interface (12) is fixed on through being threaded to connect on body (7) middle part connects said gas buffer chamber (13).
Operation principle of the present invention: referring to Fig. 1; After pressure-air enters into the first gas buffer chamber (13) by intake interface (12); Enter in the cavity (15) from interior jet channel (14) respectively; With jet gas buffer chamber (6) outside outer jet inlet channel (6) enters into, spray by outer puff prot (3) again.Liquid flows into fluid course (11) through feed liquor interface (9), from the high order end outflow of core pipe (8).Mix at cavity (15) with liquid from the pressure-air of interior jet channel ejection, under the effect of pressure-air, the air of inside breaks and clashes into, and makes the first atomizing of the liquid that flows out spray from the nozzle (2) on the air cap (1).When the liquid after the preliminary atomizing mixes with the pressure-air that outer puff prot sprays from nozzle ejection back once more, liquid atomizes under the effect of pressure-air once more, thereby reaches the purpose of liquid being carried out secondary-atomizing, makes the better effects if of the atomization of liquid.
