Aforesaid foam pump is characterized in that described pump chamber 2, large piston 3, valve piston 4 and principal post 6 consist of confined space A; Described pump chamber 2, pump pearl 10 and subpost 8 and valve piston 4 consist of confined space B.
Aforesaid foam pump is characterized in that being connected with screen element 11 and pressing mouth 12 in pump rod 5 upper ends, and screen element 11 places to be pressed in the mouth 12.
Aforesaid foam pump is characterized in that being provided with circular groove 51 in pump rod 5 bottoms, is provided with on large piston 3 tops and can inserts in the circular groove 51 and the boss ring 31 of sealing; Described valve piston 4 is annular piston, and the interior ring of valve piston 4 can seal with subpost 8.
Aforesaid foam pump is characterized in that being connected with liquid guiding tube 13 in described little pump chamber 22 lower ends.
Compared with prior art, the utility model has the following advantages:
The beneficial effects of the utility model have: 1, by spring housing is inner at seal cavity A, spring and liquid closed space B are kept apart, the liquid that enters in the confined space B can not contacted with spring, therefore, avoid the adverse consequences of spring contaminated liquid, the product design of assurance; 2, two confined space A and B are arranged in the pump chamber, confined space A is by large piston compression air, and confined space B is by the donkey press liquid.Liquid makes it to produce foam with pressurized air netware after filtration afterwards, and is simple in structure, easy to use and effective, but also have the advantages such as cost is low.
[description of drawings]
Fig. 1 is section-drawing of the present utility model;
Fig. 2 is exploded drawings of the present utility model;
Fig. 3 is block diagram of the present utility model.
[specific embodiment]
Below in conjunction with accompanying drawing the utility model is elaborated:
As shown in the figure, foam pump includes the lock bottle cap 1 that is connected with bottleneck, is connected with a pump chamber 2 in lock bottle cap 1 bottom, and this pump chamber 2 forms by the larger large pump chamber 21 of internal diameter with by the less little pump chamber 22 of internal diameter.In large pump chamber 21, be provided with large piston 3, in little pump chamber 22, be provided with valve piston 4.In large pump chamber 21, be provided with principal post 6, be provided with on principal post 6 tops and promote first principal post 6 and promote again the pump rod 5 that large piston 3 moves after moving.Be connected with subpost 8 in principal post 6 lower ends, described valve piston 4 is set on the subpost 8 slidably.Be provided with the spring 9 that is enclosed within on the principal post 6 in the described large pump chamber 21, be provided with pump pearl 10 in little pump chamber 22 bottoms.
Like this, described pump chamber 2, large piston 3, valve piston 4 and principal post 6 consist of confined space A.Described pump chamber 2, pump pearl 10 and principal post 6 and valve piston 4 consist of confined space B.
As the optimal way of the present embodiment, be connected with screen element 11 and press mouth 12 in pump rod 5 upper ends, screen element 11 places to be pressed in the mouth 12.
As the optimal way of the present embodiment, be provided with circular groove 51 in pump rod 5 bottoms, be provided with on large piston 3 tops and can insert in the circular groove 51 and the boss ring 31 of sealing.Described valve piston 4 is annular piston, and the interior ring of valve piston 4 can seal with subpost 8.
As the optimal way of the present embodiment, be connected with liquid guiding tube 13 in described little pump chamber 22 lower ends.
The utility model working process is as follows:
Press mouth 12 under open mode, when pressing, two confined space A, B volume-diminished move after the segment distance with large piston 3 contacts and to promote large piston 3 mobile because pump rod 5 promotes first principal post 6 again, and then principal post 6 is opened with the sealing position of subpost 8 separately with large piston 3 and valve piston 4.The gas pressurized is by discharging between large piston 3 and the principal post 6 and between valve piston 4 and the subpost 8.
Unclamp and press mouth, under the elastic force effect of spring 9, spring 9 promotes principal post 6 and up moves, and promotes principal post 6 returns, and principal post drives subpost and valve piston 4 up moves, the sealing position sealing of subpost and valve piston 4.Principal post promotes again large piston return simultaneously, and large piston 3 seals with the sealing position of principal post 6, and the confined space volume increases suddenly, thereby forms parital vacuum.Suck in the confined space A from large piston space groove with liquid suction confined space B in the bottle and with gas by the external atmosphere pressure effect.Repeatedly press mouth 12 several times after, will be full of liquid in the confined space B.
When again pressing mouth, because of the liquid incompressibility will by subpost, principal post and confined space A Exhaust Gas after filtration netware 11 produce foams from by spraying the mouth.
The utility model is by being enclosed within spring 9 on confined space A pump chamber 2 tops, spring 9 and confined space B are kept apart, the liquid that enters in the confined space B can not contacted with spring 9, therefore, avoid the adverse consequences of spring 9 contaminated liquids, the product design of assurance.
