Abstract

The utility model relates to a spray head, which comprises a hollow pump body, a piston and a pressure rod, wherein the piston is arranged in the pump body; the pressure rod is connected with the toppart of the piston; a liquid inlet is arranged at the bottom part of the pump body and is internally provided with a glass bead as a one-way valve; a returning spring is arranged between the piston and the liquid inlet; an open hole is arranged at the side wall of the pump body arranged above the glass bead; the open hole is connected with a liquid bleed pipe; the end part of the liquid bleed pipestretches into the pump; and the liquid bleed pipe is provided with a liquid block device. In the utility model, the liquid bleed pipe is led out from one side of the pump body so as to be matched with the spray head assembly as a main body, thereby designing the unique form; moreover, the design space is bigger, thereby improving the production level.

Description

A kind of shower nozzle

Technical field

The utility model relates to a kind of shower nozzle of pushing of container.

Background technology

Tradition is used for adorning cleaning agent, its structure of container shower nozzle of nursing materials as shown in Figure 3, comprise the pump housing 1 ' by hollow, be loaded on the piston 2 ' in the pump housing 1 ', drive the nozzle component of the depression bar 3 ' composition of piston 2 ' motion, head 32 ' is equipped with at depression bar 3 ' top, the pump housing 1 ' bottom is the inlet 11 ' of liquid, be provided with beaded glass 5 ' in the inlet 11 ' as check valve, between beaded glass 5 ' and piston, be provided with retracing spring 4 ', depression bar 3 ' inside is the liquid bleed pipe 31 ' of hollow, this bleed pipe 31 ' top also is provided with the non-return beaded glass 33 ' of liquid return, when work, earlier head 32 ' is depressed, the venting pump housing 1 ' gas inside, when unclamping head 32 ', retracing spring 4 ' is with piston 2 ' jack-up, the space that makes the pump housing 1 ' inside be positioned at the piston below forms negative pressure, under this suction function, the non-return beaded glass 33 ' of bleed pipe 31 ' falls bleed pipe 31 ' is stopped up, being positioned at the inlet 11 ' beaded glass of locating 5 ' is then picked up, liquid in the container is entered in the pump housing 1 ' the in-to-in cavity, beaded glass 5 ' is subjected to the constraint of retracing spring lower end toward top offset the time, make the gap between itself and the inlet 11 ' not too large, so that when next step, in time reset, when pressing head 32 ' once more, the beaded glass 5 ' of inlet 11 ' resets under piston 2 ' pressure inlet is in time blocked, the non-return beaded glass 33 ' of bleed pipe 31 ' then moves up under internal pressure, makes that the liquid in the pump housing internal cavities sprays from bleed pipe 31 '.The jet pipe of existing shower nozzle all is to be arranged in the head, and the structure of product is single, the dull no new meaning of profile, is not suitable for high-grade place.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of rational in infrastructure, shower nozzle that class is high.

The technical scheme that the utility model adopted is:

A kind of shower nozzle, comprise by be provided with piston in the pump housing of hollow, the pump housing, piston head is connected with depression bar, pump housing bottom is the liquid inlet, be provided with beaded glass in the liquid inlet as check valve, be provided with retracing spring between piston and the liquid inlet, the pump housing sidewall of beaded glass top is provided with perforate, and described perforate is connected with the liquid bleed pipe, the end of liquid bleed pipe is stretched in the pump housing, and the liquid bleed pipe is provided with the liquid check device.

The beneficial effects of the utility model are: the design's liquid bleed pipe is drawn from a side of the pump housing, cooperatively interacts with nozzle component as main body and designs unique moulding, and the design space is bigger, has improved the class of product.

Description of drawings

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

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a sectional structure chart of the present utility model;

Fig. 3 is traditional nozzle structure scheme drawing.

The specific embodiment

With reference to Fig. 1, Fig. 2, a kind of shower nozzle, comprise by be provided with piston 2 in the pump housing 1 of hollow, the pump housing 1, piston 2 tops are connected with depression bar 3, the pump housing 1 bottom is liquid inlet 11, is provided with the beaded glass 6 as check valve in the liquid inlet 11, is provided with retracing spring 4 between piston 2 and the liquid inlet 11, the pump housing sidewall of beaded glass 6 tops is provided with perforate 12, perforate 12 is connected with liquid bleed pipe 5, and the end 51 of liquid bleed pipe 5 is stretched in the pump housing 1, and liquid bleed pipe 5 is provided with the liquid check device.

Further, described check device comprises motion stops 52 and constraint motion stops 52 springs 53 toward top miles of relative movement that are arranged in the liquid bleed pipe 5, spring is shorter than distance between the bleed pipe screens of motion stops 52 tops above the spring slightly in the length under the natural extended configuration, and above-mentioned spring 53 is mainly used in the upward stroke of restraint plug; In addition, also can utilize modes such as card to retrain the upward stroke of motion stops 52, make motion stops can not go to the top and the bleed pipe top is clogged, when pumping liquid in container, because the pump housing 1 inside is negative pressure, automatically reset in the suction function motion stops of ordering, clog the passage between the bleed pipe and the pump housing.Motion stops 52 in the technical program is to adopt beaded glass, in addition, also can be the stopper of other shape such as plunger.

The upper and lower end of retracing spring 4 is arranged with upper and lower locating bush 41,42 respectively, this design makes retracing spring 4 more stable when work, upper and lower locating bush 41,42 respectively is provided with axially extending bore 43,44, makes that upper and lower locating bush can not influence flowing of liquid when work.In addition, the pump housing 1 also is being provided with screens 13 corresponding to following place, locating bush 42 bottoms, makes down between the end 51 of locating bush and liquid bleed pipe 5 to keep certain height, in use the situation that can not occur stopping up.

When work, earlier head 31 is depressed, the venting pump housing 1 gas inside, when unclamping head 31, retracing spring 4 is with piston 2 jack-up, the space that makes the pump housing 1 inside be positioned at piston 2 belows forms negative pressure, under this suction function, the beaded glass 6 that is positioned at 11 places, liquid inlet is picked up, liquid in the container is entered in the pump housing 1 in-to-in cavity, and on the fluid passage of liquid bleed pipe 5,52 of motion stops are sealed passage under the effect of negative pressure, prevent the liquid return on the liquid bleed pipe 5, beaded glass 6 makes it not too large with the gap that enters the mouth between 11, so that in time reset when next step in the constraint that is subjected to liquid bleed pipe end 51 when the top offset, when pressing head 31 once more, the beaded glass 6 at 11 places of entering the mouth resets under piston 2 pressure the liquid inlet is in time blocked, and the motion stops 52 of liquid bleed pipe 5 then moves up under the internal pressure effect, makes liquid in the pump housing 1 internal cavities from 5 ejections of liquid bleed pipe.

The above be the utility model preferred embodiment, it does not constitute the restriction to the utility model protection domain, so long as realize that with essentially identical means the purpose of this utility model all should belong to protection domain of the present utility model.
