Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:

Fig. 1 is the structural representation of the pump head of the utility model one embodiment;

Fig. 2 is the longitudinal sectional view of pump head shown in Fig. 1.

The specific embodiment

For technical characterictic of the present utility model, object and effect being had more clearly, understand, now contrast accompanying drawing and describe the specific embodiment of the present utility model in detail.

As shown in Figure 1-2, the pump head of the utility model one embodiment, is suitable for using on various bottles, with pump, gets the liquid in bottle.This pump head comprises bracket 2, cover the pressure head 1, the conduit 4 that is connected to bracket 2 belows that are connected on bracket 2, be connected to liquid inlet port 5 and check valve 9 on conduit 4 relative bracket one end; Between pressure head 1 and bracket 2, have inner chamber 3 and be communicated with conduit 4, pressure head 1 is provided with the liquid outlet 6 of communication with cavity 3, and liquid outlet 6 is communicated with liquid inlet port 5 by inner chamber 3 and conduit 4.The be pressed deformable and can recovering of this pressure head 1, when pressure head 1 presses down rear recovery, under gas pressure, liquid is sucked into liquid inlet port 5, then successively by conduit 4, inner chamber 3 to liquid outlet 6 outputs, check valve 9 is for preventing from entering conduit 4 liquid reverse flows.

The setting that matches of pressure head 1 and bracket 2, the periphery by both couples together respectively.Inner chamber 3 between bracket 2 and pressure head 1 is formed by the lower chamber in the upper cavity in pressure head 1 and bracket 2, and the lower chamber of bracket 2 connects this bracket 2, to be connected and to be communicated with conduit 4.In inner chamber 3, be provided with the retracing spring 7 that pressure head 1 is resetted.These retracing spring 7 one end are connected to pressure head 1 inner side, and the other end is connected to bracket 2 inner sides.Preferably, can establish in pressure head 1 inner side a boss or groove connects for retracing spring 7 one end; And/or, in bracket 2 inner sides, establish boss or indent step and connect for retracing spring 7 other ends.The preferred stainless steel material of retracing spring 7 is made.

Pressure head 1 adopts soft material to make, as silica gel etc.In the present embodiment, the silica gel pressure head that pressure head 1 is made for silica gel, has certain elasticity, flexibility, presses deformable and can recover gradually.And while pressing, by pressure head 1, be out of shape and recover pump to get liquid, and not needing to drive the even whole pump head of liquid outlet 6 to move up and down.On pressure head 1, also can be provided with air extractor vent 10, supplied gas is emitted or is entered.

Liquid outlet 6 is connected on pressure head 1 with one end.Preferably, liquid outlet 6 closes on the sidewall that bracket 2 is arranged on pressure head 1.Liquid outlet 6 can be structure as a whole with pressure head 1, adopts same material to make with pressure head 1.In order to make the fluid direction of liquid outlet 6 towards stable, on liquid outlet 6 length directions, be provided with strut member 8.Strut member 8 can be arranged on interior week of liquid outlet 6 or be embedded in liquid outlet 6 perisporiums.Strut member 8 is stay bearing plate or support tube, adopts the hard materials such as corrosion-resistant steel to make, and liquid outlet 6 can be supportted into definite shape when keeping whole pump head overall appearance, avoids liquid outlet 6 compared with soft, to be out of shape because of material.

Conduit 4 one end are connected on bracket 2, and the other end is connected with liquid inlet port 5, and liquid is delivered to liquid outlet 6 from liquid inlet port 5.Further, on conduit 4 other ends, be provided with mouth piece 41, mouth piece 41 is provided with the through hole 42 of at least one perforation.The setting of this mouth piece 41, reduces the opening of conduit 4 these ends, avoids the excessive and air pressure that pressure head 1 produces by compressive strain and recovery of opening not by liquid assimilating.Mouth piece 41 couples together after can being separately made with conduit 4, also can be made into integration.

Check valve 9 is arranged in liquid inlet port 5.Liquid inlet port 5 is column, and its one end is connected on conduit 4, and the other end forms inlet 50, and check valve 9 is movably arranged on inlet 50 in liquid inlet port 5, to prevent from entering the liquid reverse flow in conduit 4.When pressure head 1 pressurized, check valve 9 can be by inlet 50 sealings, and when pressure head 1 recovers, the separable inlet 50 of check valve 9, opens inlet 50.This liquid inlet port 5, conduit 4, mouth piece 40 and bracket 2 all can adopt the plastics such as polypropylene to make.

During this pump head work, press pressure head 1, retracing spring 7 compressions, the gas in inner chamber 3 is by liquid outlet 6 discharges such as grade, and now check valve 9 is by inlet 50 sealings; When pressure head 1 resets under retracing spring 7 effect, check valve 9 is up moved by gas pressure, thereby opens inlet 50, liquid from inlet 50 be drawn onto liquid inlet port 5, conduit 4 or and inner chamber 3, then press pressure head 1, by liquid from liquid outlet 6 outputs.Wherein, in pressing pressure head 1 and pressure head 1 reseting procedure, liquid outlet 6 does not move up and down with pressure head 1, can stablize towards required direction, guarantees that fluid direction, angle are stable, can not miss because direction, Angulation changes make liquid, easy to use.

The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification sheets and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
