Abstract

A multifunctional nozzle is provided. An inner core is a composite structure with multiple parts of an upper core, a lower core, an inner end closure and a spring, which makes the inner wall at the lower part of the upper core and the thread of the inner end closure connected, the lower outside is coupled with an adjustable sleeve, the lower core take in the shape of T, the upper end closure of the lower core is on the through hole at the center of the inner end closure, the gap of the straight tube part at the lower part passes through the through hole at the center and extends into the counterbore section at the bottom of the adjustable sleeve; a mini hole is arranged on a small end surface, besides, a ring of water outlet holes are arranged on the large end surface. The utility model has multiple functions and simple adjustment, which especially saves water, not only be used to supply the needs of the house, but also be widely used in all kinds of industries and occasions; the utility model can not only spurt at high speed and trace amount through single hole, but also can be adjusted without grades and output water in mass flow through multiple holes.

Description

Multifunctional nozzle

The utility model relates to a kind of shower nozzle, especially can be connected the multifunctional nozzle that is used with common water valve.

At present, the shower nozzle that can directly apply to the domestic life washing has only common tap and the bath head of the usefulness of having a bath.Because these traditional products are not just considered to impact washing, clear water decontamination and are economized on water this two big basic key element when initial Design Orientation, thereby mostly only have an effect of water source and water source switch, environmental protection, health, the water saving advocated with society greatly differ from each other.In the prior art, adjustable nozzle is as a kind of known non-civilian shower nozzle, though also utilized the fluid continuity principle, has extremely strong impulsive force, but because the non-civil nature of design concept makes its hole for water spraying still show excessive with respect to civilian demand, finally cause injection flow excessive, do not economize on water, impulsive force is excessive, the actual needs of domestic water can't be satisfied, industries such as fountain, fire-fighting lance, agricultural shower nozzle can only be used for.

The purpose of this utility model provides and a kind ofly both can civilianly also can be widely used in non-civil area, and can realize powerfully impacting, clear water decontamination washing, the multifunctional nozzle of special water saving also simultaneously.

Concrete scheme of the present utility model is: a kind of multifunctional nozzle, inner core are last core, following core, inner end cap, many bluk recombination structures of spring, and last core lower inner wall is connected with the inner end cap thread seal, the outside, bottom and the coupling of regulating sleeve screw thread; Following core is "T"-shaped, and its upper end cover leaves big traffic channel between lower end straight sections outer wall and this central through hole above inner end cap inner bottom surface central through hole, and the big portion of following core lower end then directly puts in the counterbore section on the regulating sleeve lower central position; Shower nozzle also is distributed with one and irises out the water hole except that being provided with on the small end face of regulating sleeve bottom the micropore of center on the large end face of middle part; Spring is arranged between core and the following core.When people when clockwise rotating regulating sleeve, the injection water type of small end face center, shower nozzle bottom is by concentrating trend to disperse, if be rotated further the top, then there is the running water ejection of big flow at large end face apopore place in shower nozzle middle part.Otherwise when the people edge rotated counterclockwise regulating sleeve, big flow running water was closed, and the injection water type at shower nozzle bottom centre place is concentrated by dispersing trend.

The advantage of such scheme is: the aperture of the miniature aperture in (1) shower nozzle small end face center, bottom is: 0.4≤φ≤2.5, the pressure potential in fluid continuity principle and running water pipe network---hydraulic pressure (P 〉=1.0kg/cm ²) acting in conjunction under, can realize the low discharge high velocity jet, powerful impact, the clear water decontamination; (2) the stepless modulation of injection water type has multiple washing function, can not only single hole micrometeor high velocity jet, and people's multiple water demand can be fully satisfied in also flow porous water outlet greatly; (3) because injection flow is minimum, and has extremely strong impact dirt-removing power and can regulate the injection water type and further reduce flow, so use special water saving according to specific requirement.

Below in conjunction with drawings and Examples the utility model is further specified

Fig. 1 is a front view of the present invention, and it is the situation when core top ring cover is lived the inner end cap central through hole down.

To be the present invention continued actual state and front view thereof after dextrorotation is regulated at regulating sleeve to Fig. 2.

Fig. 3 is the upward view of regulating sleeve, can see that from this figure also being distributed with one on the large end face irises out the water hole.

O-ring seals 14. large end faces 15. small end faces 16. big traffic channels on 1. multifunctional nozzles, 2. regulating sleeves 3. among the figure.

In Fig. 1, last core (3) bottom outer wall and regulating sleeve (2) screw thread coupling, last core lower inner wall is connected with inner end cap (5) thread seal; The top ring cover of following core (4) in inner end cap center, end through hole above, the counterbore section of regulating sleeve bottom is directly stretched in the bottom of following core, and by O-ring seal (13) realize the sealing; Spring (10) then is located between core and the following core, and all the time following core is produced normal pressure.In Fig. 1, big traffic channel (16) is shut because of the through hole that core upper end has down covered center, the interior end of inner end cap, running water can only from shower nozzle (1) go to the bottom small end face (15) center miniature aperture (6) high velocity jet and go out.When regulating sleeve was among the figure position, injection water (8) became to disperse spurting, if rotate regulating sleeve this moment in the counterclockwise direction, then injection water is concentrated by dispersing trend.In Fig. 2, following core (4) is subjected to influence that regulating sleeve (2) clockwise rotates and synchronously to top offset, following core upper end disengages with the inner bottom surface of inner end cap (5), big traffic channel (16) is opened, a large amount of running water footpath big fellow measures passage and apopore (7) from regulating sleeve middle part large end face (14) flows out, and small end face (15) center, shower nozzle (1) bottom still has and disperses the current ejection.Otherwise, when the edge rotates counterclockwise regulating sleeve, regulating sleeve is done to bottom offset with respect to last core (3), synchronously to bottom offset, up to inner bottom surface that covers inner end cap again and central through hole, shut again by big traffic channel under the effect of spring (10) and hydraulic pressure for following core, running water is flowed out by porous and becomes single micropore ejection, continue to rotate counterclockwise regulating sleeve again, the inner bottom surface of regulating sleeve bottom counterbore disengages and widens distance gradually with following core bottom, and injection water (8) is concentrated by dispersing trend.
