Meanwhile, the utility model also provides a kind of and described improved type spring external to press the container that liquid foam dispensing device is used in conjunction with, and as shown in Figures 2 and 3, described container comprises: an improved type spring external is pressed liquid foam dispensing device; One container bottle 15 for contain fluid;
Described improved type spring external is pressed liquid foam dispensing device and is formed and be tightly connected with container bottle 15 by sealing member 12.Described sealing member 12 is seal ring, gasket seal or sealant.
Principle of work and flow process that a kind of improved type spring external provided by the utility model is pressed liquid foam dispensing device and container thereof are as follows:
As shown in Figure 3, in the time that user presses the button parts 2 of pressing liquid foam dispense container that holds liquid to be allocated, drive piston rod 5 and air door 6, both move down together, at this moment the interior air pressure of the air chamber 701 in cylinder body 7 increases, be greater than outside normal atmosphere (An) (because air chamber 701 volumes reduce), aeroseal thin slice 601 on the air back-pressure air door 6 of high pressure, described aeroseal thin slice 601 is close on the air seal inclined-plane 501 of piston rod 5, thereby close the gas access passage 504 on described air seal inclined-plane 501.Simultaneously, piston rod 5 blocks the balancing air holes 703 of cylinder body 7 by sealing lip limit 505 on outer wall and outer wall lower seal lip limit 506, at this moment, air just enters in the gas-liquid mixed chamber 503 piston rod 5 by gas flow channel 705 from air chamber 701, simultaneously, liquid enters in the gas-liquid mixed chamber 503 piston rod 5 by liquid rising passway 704 from the fluid chamber 702 of cylinder body 7, now, the scalene cone tight seal of the fluid chamber 702 of sealing element 13 and cylinder body 7, liquid is trapped in fluid chamber 702, at this moment, the gas-liquid mixed chamber 503 interior mixing of liquid-to-air in piston rod 5, gas-liquid mixture is up by the fine and close gauze 401 of mesh porous member 4 lower ends, foam for the first time, the liquid of foaming continues the up fine and close gauze 401 of mesh porous member 4 upper ends that passes through for the first time, foams for the second time, and finally abundant exquisiteness, stable foam export out from button.Wherein, button parts 2 continues when descending, and the balancing air holes 703 of cylinder body 7 is crossed on sealing lip limit 505 on the outer wall of piston rod 5, and the air of outside enters in container bottle 15 by balancing air holes 703, keeps the air pressure of container bottle 15 the insides the same with outside atmosphere pressure.
In the time of release-push parts 2, it is up that spring 8 promotes piston rod 5, at this moment, gas access passage 504 on piston rod 5 is opened (because air chamber 701 the inside air pressure are less than outside normal atmosphere (An), the aeroseal thin slice 601 of air door 6 pushed away from gas access passage 504) outside air and is entered smoothly air chamber 701 inside.Simultaneously; When piston rod 5 is up with dynamic seal pull bar 11 by the first buckle 507, sealing pull bar 11 drives hydraulic seal parts 10 up by the hydraulic seal conical surface 1102, at this moment; The liquid sealing ring 1001 of hydraulic seal parts 10 and the sealing pull bar hydraulic seal conical surface 1102 closely cooperate, thereby, the liquid rising passway 704 of fluid chamber 702 is closed, piston rod 5 drives hydraulic seal parts 10 and sealing pull bar 11 to continue up, fluid chamber 702 volumes continue to increase, and pressure diminishes; Sealing element 13 is pushed (pressure that container bottle 15 the inside air pressure pressure are greater than fluid chamber 702), and the hole of liquid suction passage 14 and cylinder body 7 lower ends enters fluid chamber 702.The liquid of button parts 2 was pumped in covering by last circulation.
As above by ceaselessly pressing button parts 2, just can constantly the liquid in container bottle 15 be pumped into and form foam ejection.
In use, in order to reduce the deteriorated danger of function, also in order to obtain generally better guiding between piston rod 5 and cylinder body 7, lubricant reservoir groove 502 is set on piston rod 5, this lubricant reservoir groove 502 is As time goes on by dispense aperture, distribute the lubricant of for example silicone oil and so on, this lubricant can improve the guiding between air chamber 701 inwalls of piston rod 5 and cylinder body 7.
It should be noted that; above content is in conjunction with concrete embodiment further detailed description of the utility model; can not assert that detailed description of the invention of the present utility model only limits to this; under above-mentioned guidance of the present utility model; those skilled in the art can carry out various improvement and distortion on the basis of above-described embodiment, and these improvement or distortion drop in protection domain of the present utility model.
