Abstract

The utility model relates to a liquid nozzle. Primarily, a plurality of recesses are arranged on peripheral surfaces at the bottom of the pushing region of a supporting pipe in a nozzle structure composed of the supporting pipe, a spring, a steel ball pipe, and a pushing pipe. The positions of the recesses is the same as the position of a convex ring when the pushing pipe is extruded to the tail end. When the liquid nozzle is not used, residual pressure is discharged from the space of the recesses; while the disadvantage that remainder often lightly exudes at a nozzle site can be prevented.

Description

Liquid nozzle

The utility model relates to a kind of fluid jetting head, be mainly to prevent that shower nozzle from using later because partly remnant pressure remains in being in the charge of and the shortcoming that causes liquid partly slowly to ooze out from the shower nozzle place, mainly preset a plurality of recesses at the district's bottom side face of being in the charge of of pushing, the position that this recess location prominent ring proper and the ejector sleeve end is urged to the bottom is suitable, the pressure of remnant can be released via the space of this recess, and prevent that effectively defective material from oozing out from the shower nozzle place.

In the application of shower nozzle, modal in daily life is as hair jelly shower nozzle, cleaning solution shower nozzle etc., the principle of its application is to make the liquid pressurized in the bottle and be extruded in the mode of pushing to make progress, and spray via the more small-bore opening of shower nozzle, such design is obviously very convenient in the use, adding now more has the shower nozzle of multiple pattern available, and the article of feasible application shower nozzle and people's life are closer.Yet; in the process of using; after finishing using, no longer push showerhead, just be placed on the desktop; in the time will using for the second time; regular meeting finds have the defective material of many Yus to accumulate in outer surface at the position of shower nozzle, and the mud shape state of semi-wet gives people's sensation like a hen on a hot girdle, more may be stained with many impurities and dust because of the existence of mud shape thing; make the people that uncleanly impression more be arranged, must be in addition again with its removing.In the process that whole operation is used, just allow the people feel very inconvenient, for the convenience purpose of sprinkler design tangible discount has been arranged just, and such phenomenon is not seen improvement always., the function of shower nozzle itself, structure can spray the fluid column of multiple pattern though constantly improving, but all be stained with the mud shape defective material that amasss in the shower nozzle exit in the time of will using always makes the people be difficult to accept at every turn, so chat the today that can improve constantly at product, above-mentioned condition needs to improve really.

Main purpose of the present utility model is to provide a kind of structure improved fluid jetting head, be to establish with recess being in the charge of the position that cooperates with ejector sleeve, make ejector sleeve prominent encircle to such an extent that cooperate and form the pipeline of pressure release, release, effectively prevent above-mentioned phenomenon and the pressure of remnant can be given earlier with recess.

The utility model provides a kind of structure improved fluid jetting head, mainly be embedded suction pipe and stretch in the liquid level in a bottom surface of being in the charge of that connects, be in the charge of the then sheathed ejector sleeve of end face, the ejector sleeve top is communicated with spray nozzle part, press down with being in the charge of the position that cooperates with respect to ejector sleeve and to be provided with several recesses, make to be in the charge of between end and ejector sleeve to form slight void in the interior sidewall surface of being in the charge of.

In a kind of scheme, the end face of being in the charge of of aforesaid structure improved fluid jetting head forms one and pushes the district, and the below forms the compressional zone, and the ejector sleeve end then forms a prominent ring and just can be butted on the inwall of pushing the district and move.

In another kind of scheme, the ejector sleeve bottom surface of aforesaid structure improved fluid jetting head is embedded a steel ball pipe, and steel ball pipe bottom surface is open-minded, in be embedded steel ball, the steel ball position is provided with and wears groove relatively, and steel ball pipe below butt one spring, the end of spring then supports and is placed on the protruded stigma of bottom, compressional zone.

Further specify architectural feature of the present utility model and purpose below in conjunction with accompanying drawing.

Fig. 1 is an exploded view of the present utility model.

Fig. 2 is a combination view of the present utility model.

Fig. 3 is an another kind of embodiment plane of the present utility model.

Please referring to Fig. 1, Fig. 2, the utility model mainly by be in the charge of 10, spring 11, steel ball pipe 12 and ejector sleeve 20 etc. form, wherein being in the charge of 10 is the body that open at two ends, topmost bore is bigger for it, and for pushing district 13, its below bore is less, be compressional zone 14, pushing district 13 can inserting for ejector sleeve 20.And 14 bottom surfaces, compressional zone form the cylinder 141 of a projection, but ammunition feed spring 11 1 ends are sheathed on it.Be in the charge of 10 bottom then can sheathed one stretch into subsurface suction pipe 30(please referring to Fig. 3).

Steel ball pipe 12 is the thin and wide body in lower end in a upper end, and its bottom surface is open-minded, and inside is embedded a steel ball 121, and body is offered several with respect to the position of steel ball 121 and worn groove 122, to push away on can be with steel ball 121 during suction on the liquid liquid is gone out by wearing groove 122 place's percolations.

Ejector sleeve 20 is a cap shape body, its upper and lower side is all open-minded, its end face is embedded in the shower nozzle opening is communicated with the ejector sleeve 20 end face places of opening, and its bottom surface periphery forms prominent ring 21, just cooperate with the madial wall of pushing district 13, form the pattern of piston action, wherein then can go into wherein, make the liquid that goes out by wearing groove 122 upper reaches can pass ejector sleeve 20 and by showerhead 40 ejections for the top of steel ball pipe 12.Principal character of the present utility model is that just the bottom surface of the portion of pushing 13 is with respect to ejector sleeve 20 prominent rings 21 positions that press down, lateral circle surface is provided with a plurality of recesses 131 in it, the degree of depth that this recess 131 caves in is the working depth of " atomic " only, make press down showerhead after, prominent ring 21 just is formed with minimum space with recess 131 apposition positions, make after finishing using, the pressure of remnant just can be released by this gap, does not still make part liquid rise to the shower nozzle place again to the liquid pressurization and can not cause after using.
