Description

The sprayer-intermittent shower nozzle

The utility model relates to liquid jet atomization device.

Liquid dispensing apparatus, be widely used in various crops such as agricultural, forestry deinsectization, accelerate the ripening, apply fertilizer, the medical and health epidemic preventing working of occasions such as hotel, restaurant, family, and industry such as the daily-use chemical industry in the daily life, washing agent, cosmetics, cosmetology.Along with The development in society and economy, living standards of the people improve constantly, and sprayer unit more and more is widely used, in existing sprayer product, the most common with hand-pulling, its defective has (1) vacuum phenomenon when easily producing vacuum spraying, and liquid can't be sucted; (2) when piston up-down, can produce air and reflux, influence atomizing effect; (3) nothing is closed function and is easily caused fluid seepage.

The purpose of this utility model is to overcome the defective of prior art and provides that a kind of injection, atomizing effect are good, the sprayer-intermittent shower nozzle of no liquid seepage phenomenon.

By the foregoing invention purpose, embodiment of the present utility model is: include the fillet of screw that is spirally connected with bottle, be connected the main body at fillet of screw top, main body is surrounded covering and is had vertical cavity, inclination chamber and the horizontal cavity that interpenetrates by case, is provided with the steel ball seat of the suction pipe of can pegging graft and the steel ball of keying valve port in the vertical cavity; Be provided with piston that can slide vertically and the piston spring that resets in the inclination chamber; Be provided with in the horizontal cavity with the branch that has liquid outlet groove of main body close-fitting and comb one's hair, divide and to comb one's hair outer to be the nozzle of the rotatable adjusting that combines with main body simultaneously, liquid outlet groove and fluid aperture to be arranged on the nozzle, and prevent the hermetically-sealed construction that air refluxes; Trigger is connected with main body, and its improvements are that described piston is provided with the piston seat by the trigger promotion that slides synchronously with it outward; The described hermetically-sealed construction that prevents that air from refluxing is that activity is engaged in thimble and the spring in the main body liquid outlet channel.

The utility model is owing to adopted double-piston, dual spring and prevented the air return-flow structure, air backflow phenomenon when vacuum phenomenon when having solved vacuum spraying effectively and spraying, spray effect is improved greatly, and on combing one's hair, branch designed multiple liquid outlet groove, ejection function is increased, can satisfy the injection needs of different articles for use, nozzle can rotate and have closing function arbitrarily again, can prevent fluid seepage.

Embodiment to the utility model is described in detail again according to above accompanying drawing.

Sprayer-intermittent shower nozzle (referring to Fig. 1-5) is the critical piece of sprayer, with plastics is main material, it has the fillet of screw (14) that is spirally connected with the bottle exchange, main body (2) is connected fillet of screw top with barb, main body is provided with the case (1) that the same encirclement that is connected by barb covers outward, main body has vertical cavity, inclination chamber and the horizontal cavity that interpenetrates, connect by liquid-through hole (20) and return-air hole (15) between vertical cavity and the inclination chamber, connect by liquid outlet channel (3) between inclination chamber and the horizontal cavity.

Be pressed into steel ball seat (17) by the below in main body (2) vertical cavity, grafting suction pipe (16) in the steel ball seat, the upper end is provided with the steel ball (18) that opens and closes valve port, and is being provided with conical uniform 6 little muscle (19) of being of locking ball over against the steel ball position.

Be provided with piston (5) that can slide vertically and the piston spring (4) that resets in the inclination chamber, piston is provided with the piston seat (6) that slides synchronously with piston outward, the power that they slide is promoted and is obtained by trigger (12), piston and piston seat slide synchronously and are equivalent to two pistons, adopt double-piston to solve the vacuum phenomenon that causes when single piston is sprayed effectively, two pistons are finished function separately, wherein piston is finished spraying function, and piston seat is finished the function of return air, can not produce vacuum phenomenon when making spraying.

Be provided with in the horizontal cavity with the branch that has liquid outlet groove of main body close-fitting and comb one's hair (9), dividing the liquid outlet groove on combing one's hair can be to be the wire groove (22) that wire is sprayed; Also can be the atomizing groove (21) that is atomized spray, the atomizing groove be a skewed slot; The combination that can also have wire groove and atomizing groove simultaneously makes it have simultaneously that wire is sprayed and the function of atomized spray, by user's function of choosing any one kind of them.Dividing outside combing one's hair is the nozzle of doing to rotate adjusting (10) that combines with main body the while, the fluid aperture (11) that liquid outlet groove (23) and center are also arranged on the nozzle, in being square, nozzle is the concentric conjoined structure of three rings outward, square four surfaces are marked with the sign of aiming at wire groove, atomizing groove and closing, and select when using for the user.It not only cooperates with subject activity but also cooperates with the branch activity of combing one's hair, so can do rotation regulates, on the inner surface that encircles in its liquid outlet groove is located at, when this liquid outlet groove (23) with divide the wire groove (22) comb one's hair on time, the ejection liquid be wire, when with the atomizing groove (21) on time, the liquid of ejection is spray pattern, when with the circular surfaces of slotless on time, be closed condition.Also be provided with the hermetically-sealed construction that prevents that air from refluxing in the horizontal cavity, the sealing structure comprises that activity is engaged in thimble (7) and the spring (8) in the liquid outlet channel (3), liquid outlet channel in the horizontal cavity is stepped, so thimble also is match stepped, spring withstands thimble, produce pressure during spraying, air is refluxed.

Trigger (12) is connected with barb with main body (2), and its another connecting lever is supported on recessed shoulder place, piston seat (6) end, and the power that promotes the slip of piston and piston seat is imported thus.The cambered surface of trigger is provided with anti-skid structure, and this anti-skid structure can be convex tendon shape (13) or groove shape, and the design selects many uniform convex tendon shapes for use.

When needs spray, at first select to divide the shape of (9) liquid outlet groove of combing one's hair, swivel nozzle (10) divides comb one's hair wire groove or atomizing groove sign by closed condition to aiming at.Because steel ball (18) is sealing valve port, liquid does not also enter liquid outlet channel (3) in the bottle, be that sprayer remains static, at first pull trigger (12) 5-6 time in advance this moment, make bottle interior liquid open the valve port of sealing by steel ball (18) and enter in the inclination chamber through suction pipe (16), and then pull trigger, the process of pulling a pine at one is an oscillation cycle, piston (5) also is brought to piston seat (6), piston seat is pushed to above return-air hole (15) position, and outside air is entered in the bottle by return-air hole, avoids occurring vacuum state in the bottle, when piston spring (4) when resetting, piston seat is pushed down, and return-air hole is closed state, can prevent leakage, simultaneously, air is discharged by nozzle fluid aperture (11) in the main cavity, and liquid just is wire or the ejection of atomizing shape by liquid outlet channel, and ejection back center (7) is at spring (8) effect lower seal, prevent that air from refluxing, and also finished the step once task of spraying.The utility model is applicable to the occasion that needs interrupted injection.
