Embodiment one:

As shown in Figure 1, the utility model partly is made of pressure head 1, pressure pipe 2, piston sleeve 3, piston 4, cylinder pipe 5, filter screen pipe 6 etc.There is a L shaped pipeline 11 pressure head 1 inside; Pressure pipe 2 is positioned at pressure head 1 below, is hollow tube, and pressure pipe 2 bottom outer rims have a bulge loop 21; One filter screen pipe 6 is arranged between pressure head 1 and pressure pipe 2, and the two ends of this filter screen pipe 6 are respectively equipped with fie screen 61.

As Fig. 1, shown in Figure 3, piston sleeve 3 is made of pipe portion 32, spring seat 33, and pipe portion 32 is positioned at pressure pipe 2 belows, and two radial direction through hole 321 are arranged below its tube wall.Piston 4 is by last collar extension 41, following collar extension 42, and ring portion 43, collar 45 constitute, and piston 4 has big external diameter, slides over piston sleeve 3 tube walls 32 outsides, is made by soft plastic.In the present embodiment, ring portion 43 is penetrated with four air holes 44 vertically, and the bottom surface outer rim of ring portion 43 ring set again has a whole flange 441 that encloses dimpling.Collar 45 is placed in the outer rim of 4 times collar extensions 42 of piston, and the apical margin of this collar 45 radially extends a thin slice ring 451, and thin slice ring 451 lucky contacts and cover four air holes 44 on flange 441.

Again as shown in Figure 1, cylinder pipe 5 is a socket shape wide at the top and narrow at the bottom, be enclosed within the outside of piston 4, the top is threaded with loam cake 51, or makes up in the buckle mode with loam cake, and the below is the inlet 52 than minor diameter, form a foam tank 50 between this inlet 52 and the piston 4, foam tank 50 inboard ring walls have a circle catch ring 55, and there is an one-way valve 53 at 52 places that enter the mouth, and a spring 54 is arranged between one-way valve 53 and the spring seat 33.One-way valve 53 is general ball in the present embodiment.

Below in conjunction with Fig. 1 and Fig. 2 the utility model working principle is described.As shown in Figure 1, when using Foam emulsion pump, press down pressure head 1, the bulge loop 21 of pressure pipe 2 is pushed against the last collar extension 41 of piston 4, and pressure pipe 2 drive piston sleeves 3 move down, impel the outer rim of its spring seat 33 to leave the following collar extension 42 of piston 4, therefore the strength that presses down is pressurized to through pressure pipe 2, piston 4 on the emulsion in the cylinder pipe 5, foam tank 50 pressure inside make thin slice ring 451 push against flange 441 and then four air holes 44 are sealed, emulsion is just by down collar extension 42 and spring seat 33 outer intermarginal spaces, and via through holes 321 enters in the L shaped pipeline 11 and extrudes outside the bottle.

Instantly press and finish, behind the relieving pressure head 1, as shown in Figure 2, the effect that piston sleeve 3 is subjected to spring 54 to make progress elastic force is risen, and piston sleeve 3 outer rims upwards push against the following collar extension 42 of piston 4, and emulsion is flowed out the gap sealing.Shown in Fig. 4 enlarged view, piston sleeve 3 is subjected to the upwards effect continuation rising of elastic force of spring 54, air reduces gradually in the foam tank 50, form vacuum gradually, small gap between the thin slice ring 451 of collar 45 and the flange 441 just makes that the pull of vacuum in the foam tank 50 sucks air rapidly by air hole 44, simultaneously, again as shown in Figure 2, pull of vacuum is also opened ball 53 emulsion in the 52 suction foam tanks 50 that enter the mouth.Because thin slice ring 451 itself as thin as a wafer and have elasticity, along with the rising of piston sleeve 3, thin slice ring 451 is clapped because of the infiltration slight vibration of gas and is stirred air and emulsion, just emulsion can be stirred into foam-like in advance, guarantees that foam forms.When treating that piston sleeve 3 rises to top, foam latex just can be stored in the foam tank 50, when waiting press down Foam emulsion pump next time, extrusion be exactly the foam-like emulsion.So go round and begin again, just can reach the purpose that is pre-mixed air and emulsion, produces foam latex.
