Description

The novel foam pump

[technical field]

The utility model relates to a kind of Liqiud-gas mixing device, refers in particular to gas-liquid mixed is become to press the foam pump of taking out behind the foam.

[background technology]

Current, be loaded with the bottle of wash water liquid, shampoo or other liquid, what have has loaded onto foam pump at its bottleneck, as shown in Figure 1, foam pump includes bottle cap 100, body 101, head 102, gas piston 103, liquid piston 104, valve 105, pin post 106, spring 107, glass bead 108, subpost 109, suction pipe 110 and Netcom 111 etc., bottle cap 100 is screwed on behind the bottleneck, and the suction pipe 110 of body 101 belows is inserted in the solution of bottle.When operation, press down head 100, gas piston 103, liquid piston 104, when valve 105 and pin post 106 move down, valve 105 is blocked the induction opening 1031 of gas piston 103,108 of glass beads get lodged in the inlet 1011 of body 101, so form positive air pressure behind the gas pressurized in air storing cavity A, then form positive hydraulic pressure behind the liquid pressurized in the liquid storage cylinder B, positive air pressure enters among the C of gas-liquid mixed chamber after pushing the thin slice 1051 of valve 105 tops open, the liquid of positive hydraulic pressure also enters the C of gas-liquid mixed chamber in the gap between pin post 106 tops and hydraulic piston 104 tops, so gas in the hybrid chamber, outlet 1021 from head 100 liquid fully is mixed into foam in Netcom 111 after is pumped, and realizes the process that pump is got foam.Then, unclamp head, under retracing spring 107 effects, gas piston 103, liquid piston 104, valve 105 and pin post 106 up move and reset, thin slice 1051 is sealed the air by-pass passage in the middle of gas, the liquid piston 104,105, pin post 109 is then sealed liquid piston 105 upper ends, air storing cavity A and liquid storage cylinder B all form negative pressure, finish the gas storage process the air storing cavity A so extraneous air enters after induction opening 1031 is pushed valve 105 open, and the liquid in the suction pipe 110 is pushed and is entered into liquid storage cylinder B behind the glass bead 108 and finish the liquid storage process open.The gas of the foam pump of present stage, liquid piston be separately independence be contained in different positions, this will certainly cause the parts of foam pump more, the assembling more complicated causes that to produce adult higher; And the cooperation between the parts in use for some time may be not too flexible, causes stability lower.
