Description
Technical field
The present invention relates to a kind of foam-dispensing device and its containers more particularly to a kind of spring external to press liquid foam
Distributor and its container.
Background technique
Carry out what liquid distribution was allocated generally by liquid dispensing apparatus at present, the non-foam shape of the content of distribution
Shape (liquid or colloidal), such as everybody daily dish washing liquid or hand cleanser being commonly used, the pump of this liquid dispensing apparatus
Content is easy to be lost out, so that cannot make full use of, cannot sufficiently contact when in use with object.
And liquid foam is mainly to pass through that activating agent is added in a liquid, is steeped when generating in the mixed process of liquid and gas
Foam, liquid foam are foamed by liquid foam distributor.
There are also liquid foam distributors at present in the market, but are substantially through liquid pump and carry out foaming distribution
, by comparative analysis, it is believed that there are the following problems in existing liquid foam distributor:
1, the guidance meeting aging over time between the cylinder body and piston pumped, to reduce the function of pump.This
The decrease of the guidance of kinds of structures also results in leakage air, so that pumped air amount is few, causes foam profiles unstable.
2, between the cylinder body and piston pumped, cooperation sealing is too tight, unsmooth smooth so as to cause shuttling movement above and below piston,
Consumer is needed in this way in use, the strength of pressing is very big.
3, known distributor consumer can issue sharp noise of uttering long and high-pitched sounds when in use.
4, consumer is in use, is easy to appear liquid and is leaked in cylinder body container, and product shuttling movement has some setbacks, card
Extremely；To influence product function.
5, the foam that existing distributor generates is not of uniform size, not careful abundant enough.
6, the metal spring in the pump housing and metal sealing sphere are contacted with liquid contents are pumped out, to cause secondary pollution
(metal oxidation and rusting), therefore very high (anti-oxidant getting rusty property is required to metal spring and metal sealing sphere antioxygenic property
Can), while height is also required to filling liquid and filling environment, lead to high production cost.
Meanwhile it has been found that there are the foam pump of some spring externals having disclosed, for example Chinese utility model
" novel external spring device foam pump " that number of patent application is 201020289663.7, application No. is 201110128683.5
" a kind of foam pump with external spring ", central scope are to consider how that the spring for resetting press head is arranged,
It is all that reset spring is arranged in fluid chamber, the problem of this brings is exactly that spring impregnates always in previous foam pump installation
In a liquid, there is 6th as previously described the problem of, use external spring that can bring with effective solution this problem
New problem be how effectively to make integral foam pump configuration more simple and compact and that pressing can be made to stablize is smooth, be this
Field technical staff problem in the urgent need to address.

It is shown, the balancing air holes 803 for balance cylinder block and ambient pressure are provided on the air chamber 801 of cylinder body 8；The liquid of cylinder body 8
A seal member 14 for being used on and off liquid rising passway 804 is equipped in body cavity 802.Seal member 14 is sphere.
As shown in Fig. 2, the container being used cooperatively with spring external pressing liquid foam dispensing device includes: one for containing
The container bottle 16 of tapping body；Spring external presses liquid foam dispensing device and forms sealing by sealing element 13 and container bottle 16
Connection.Sealing element 13 is sealing ring, gasket seal or sealant.
The working principle of a kind of spring external pressing liquid foam dispensing device and its container provided by the present invention and
Process is as follows:
As shown in Fig. 2, hybrid junctioin 5 tightly suppresses mixing when pressing the button parts 2 of the liquid foam distribution container
Device 6, the two moves downwardly together, at this moment the air outside air seal component 7 enter the gas in the air chamber 801 of cylinder body 8 into
Enter channel 701 and is closed (the i.e. air seal scalene cone of the circular conical surface (not shown) of hybrid junctioin 5 and air seal component 7
704 are fitted close), meanwhile, air seal component 7 passes through sealing lip 702 on outer wall, seals under lip 706, outer wall in outer wall
The balancing air holes 803 that 705 three of lip carrys out dual block cylinder body 8 are sealed, button parts 2 continue to downlink, gas in air chamber 801
Pressure rises and (is greater than outside environment atmospheric pressure), and air just enters in mixer 6 from air chamber 801 by gas flow channel 805
Gas-liquid mixed channel 601, meanwhile, liquid enters mixer 6 by liquid rising passway 804 from the fluid chamber 802 of cylinder body 8
Gas-liquid mixed channel 601, at this point, scalene cone (not shown) tight seal of the fluid chamber 802 of seal member 14 and cylinder body 8, liquid
Body is trapped in fluid chamber 802, and at this moment, liquid-to-air mixes in the gas-liquid mixed channel 601 in mixer 6, and gas-liquid is mixed
Several through-holes 503 on the initial foam generation part 502 that object uplink passes through the lower end of hybrid junctioin 5 are closed, into initial bubble
Room 501 occurs for foam, generates foam, this is that gas-liquid mixture foams for the first time；Liquid after foaming for the first time continues uplink and passes through
The fine and close gauze 401 of 4 lower end of mesh porous member, at this moment carries out foaming for second；The liquid of second of foaming continues uplink
By the fine and close gauze 401 of 4 upper end of mesh porous member, this is to carry out third time foaming, finally enriches fine and smooth, stable bubble
Foam exports out from button.When button parts 2 continue traveling downwardly, lip 702 is sealed on the outer wall of air seal component 7, crosses cylinder
When the balancing air holes 803 of body 8, the air of outside is entered in container bottle 16 by balancing air holes 803, keeps 16 the inside of container bottle
Air pressure and outside atmosphere pressure.
When release button component 2, spring 9 pushes 6 uplink of mixer, to drive gas close by the first buckle 603
7 uplink of component is sealed, the gas inlet passages 701 that at this moment outside air enters air chamber 801 open the (oblique cone of hybrid junctioin 5
Face is separated with the air seal scalene cone 704 of air seal component 7), air can smoothly enter into air chamber 801.Meanwhile mixer 6
While by 603 band 12 uplink of dynamic sealing pull rod of the first buckle, sealing pull rod 12 is by the hydraulic seal conical surface 1202 with hydrodynamic
11 uplink of body seal member, at this moment, the liquid sealing ring 1101 of liquid sealing member 11 and the hydraulic seal cone of sealing pull rod 12
Face 1202 is fitted close, so that the liquid rising passway 804 of fluid chamber 802 is closed, mixer 6 drives 11 He of liquid sealing member
It seals pull rod 12 and continues uplink, 802 volume of fluid chamber increases, and pressure becomes smaller；Seal member 14 is pushed (16 the inside gas of container bottle
Pressure is pressed to be greater than the pressure of fluid chamber 802), the hole of 8 lower end of liquid suction passage 15 and cylinder body enters fluid chamber 802.Cover quilt
Last circulation pumps out liquid.
As above by ceaselessly push button component, constantly the liquid in container can be pumped into and form bubble jet
Out.
In use, in order to reduce the risk of function deterioration, also for air seal component 7 and cylinder body 8 it
Between obtain generally better guidance, on air seal component 7 be arranged lubricant reservoir slot 703, the lubricant reservoir slot 703
It is open over time by distribution, to distribute the lubricant of such as silicone oil etc, which can improve air seal
Guidance between component 7 and the inner wall of cylinder body 8.
It should be noted that the above content is combine specific embodiment made for the present invention further specifically
It is bright, and it cannot be said that a specific embodiment of the invention is only limitted to this, under above-mentioned guidance of the invention, those skilled in the art can
To carry out various improvement and deformations on the basis of the above embodiments, and these are improved or deformation falls in protection model of the invention
In enclosing.
