Structure of the present invention comprises three sealing systems:
1, the sealing between the upper sealing ring of the lower sealing ring of choker relief valve and big piston;
2, the sealing between the lower seal inclined-plane of going up sealing inclined-plane and big piston of adapter sleeve;
3, the sealing between the lower seal inclined-plane of going up sealing inclined-plane and valve piston of needle-valve.
But above three sealing systems are not to be in sealing state simultaneously.
Principle of work is:
Under normal condition, the bottom chamber of cylinder has been full of fluid, and is air in the upper chamber of cylinder.At this moment, the lower sealing ring of choker relief valve is not nested with sealing with the upper sealing ring of big piston, and pore is with upper and lower two parts space UNICOM of being cut apart by big piston in the upper chamber.But, because sealing is replaced mutually with the lower seal inclined-plane of big piston in the sealing inclined-plane of going up of adapter sleeve, therefore the indoor gas of upper chamber of air cylinder can not enter the inner chamber of choker relief valve, simultaneously, sealing is replaced on the lower seal inclined-plane of going up sealing inclined-plane and valve piston of needle-valve mutually, so the indoor fluid of lower chamber of air cylinder can not enter the hollow channel of connecting rod.
Press down gland slightly, thus the cylinder lower edge of gland replace the shirt rim of choker relief valve and press down choker relief valve, but this moment big piston and the position of valve piston remain unchanged.The lower sealing ring of choker relief valve is nested with sealing mutually with the upper sealing ring of big piston, makes big piston two parts space up and down isolated.Because the choker relief valve while is also replaced adapter sleeve downwards and moves down, so the lower seal inclined-plane disengaging of going up sealing inclined-plane and big piston of adapter sleeve, the air of the indoor big piston of upper chamber of air cylinder below can enter choker relief valve; Simultaneously, second screen cloth of choker relief valve also promotes connecting rod downwards and needle-valve together moves down, thereby the lower seal inclined-plane of going up sealing inclined-plane and valve piston of needle-valve is broken away from, and the indoor fluid of lower chamber of air cylinder can enter the hollow channel of connecting rod.
Continue to press down gland, thus the lower sealing ring of choker relief valve replace the coupling link of big piston and press down big piston, thereby the connecting rod lower edge is also replaced the coupling link of valve piston and is pressed down valve piston.The space of the indoor big piston of upper chamber of air cylinder below is by Zhu Bu Ya Shrink, and gas constantly enters the choker relief valve inner chamber via the gas passage between choker relief valve and the adapter sleeve; And the indoor space of lower chamber of air cylinder is also by Zhu Bu Ya Shrink, and fluid fluid passage between the cylinder in needle-valve and the valve piston constantly enters the hollow channel of connecting rod.Gas and fluid mix in hybrid chamber, form abundant foam through second screen cloth and net first screen cloth beyond the Great Wall on the choker relief valve again, from runner and the outlet ejection of gland.
Behind the ejection aequum, discharge gland, under the effect of spring restoring force, adapter sleeve and choker relief valve move up.In the upper chamber of cylinder, sealing is replaced again mutually with the lower seal inclined-plane of big piston in the sealing inclined-plane of going up of adapter sleeve, and the lower sealing ring of choker relief valve breaks away from mutually with big piston upper sealing ring, thereby pore is opened, air progressively enters the space of big piston below by pore from big piston top, big piston is resetted.And in the bottom chamber of cylinder, connecting rod and needle-valve rise, and sealing is replaced again mutually with the lower seal inclined-plane of valve piston in the sealing inclined-plane of going up of needle-valve, and the disk of needle-valve bottom also will drive the valve piston rising and reset.
On the basis of such scheme, described first screen cloth is identical with second mesh structure, screen cloth is divided into two-layer up and down, between upper strata and lower floor, form interconnection, be equipped with diamond-shaped meshes on the upper and lower, and stagger in upper strata diamond-shaped meshes and lower floor diamond-shaped meshes position, form passage through upper strata diamond-shaped meshes, interconnection and lower floor's diamond-shaped meshes.Adopt the special design that has diamond-shaped meshes and stagger up and down of the present invention, mesh is not to make screen cloth straight-through up and down, but forms a curved passage, and so design is convenient to produce the foam of even refinement.
On the basis of such scheme, in order to prevent from netting plug and the rotation of choker relief valve in the gland cylinder, the cylindrical inner wall cross section of gland is arranged with a pair of circular arc convex tendon, the outer wall cross section of described net plug cylinder and choker relief valve cylinder forms respectively and the scarce face of the circle of circular arc convex tendon coupling, makes net plug and choker relief valve be radially positioned in the inboard of gland cylinder.
On the basis of such scheme, because choker relief valve also will promote adapter sleeve downwards when pressing down with gland, the cylinder lower edge of choker relief valve need be replaced on the bulge loop of adapter sleeve, guarantee simultaneously the lower seal inclined-plane of big piston and going up when sealing the inclined-plane disengaging of adapter sleeve again, air can enter the gas flow between choker relief valve and the adapter sleeve from the side, therefore, the root edge of described choker relief valve cylinder is provided with a plurality of double wedges, form air intake between adjacent double wedge, air enters in the choker relief valve by this air intake; Thereby mix with fluid for more air is entered in the choker relief valve, the inside face top of choker relief valve cylinder is provided with many fins, forms air by-pass passage between adjacent fin.
On the basis of such scheme, wide diameter portion is formed at described connecting rod top, is provided with a plurality of double wedges at the apical margin of wide diameter portion, forms gas-liquid UNICOM mouth between adjacent double wedge.When gland is released, thereby withstanding the expansion neck of connecting rod under action of the spring, adapter sleeve promotes the connecting rod rising.This expands neck can be various forms such as step, the conical surface.By this gas-liquid UNICOM mouth, air and fluid contact and mix, and form foam.
On the basis of such scheme, for elongated needle-valve being positioned at the inboard of connecting rod, can not stop up simultaneously the hollow channel of connecting rod again, the hollow channel middle part of described connecting rod is provided with dolioform hole clipping, the top of described needle-valve cylinder penetrates this dolioform hole clipping and by two straight flanges chucking of dolioform hole clipping, and between two bent limits of cylinder both sides and dolioform hole clipping, form runner, below this dolioform hole clipping, the periphery of needle-valve cylinder is provided with many radially convex tendons, forms runner between adjacent convex tendon.
Structure of the present invention also will inwardly be compressed needle-valve by convex tendon is set not only by the front end screens of hole clipping with needle-valve by connecting rod after stretching into the hollow channel of connecting rod, thereby make the needle-valve location.The shape of hole clipping should not only limit to said dolioform here, can also be square, rhombus, ellipse etc., so long as inequality with columniform needle-valve shape, all should be protection scope of the present invention by the shape that needle-valve can be blocked.And also can change work at needle-valve arranged outside convex tendon convex tendon is set in the connecting rod inboard, so long as the needle-valve location can not stopped up the hollow channel of connecting rod simultaneously again, also all should be protection scope of the present invention.
On the basis of such scheme, described adapter sleeve bottom surface is provided with a circular groove, and locate in circular groove the upper end of spring.
On the basis of such scheme, bottom, described lower chamber of air cylinder chamber is provided with a spring groove, and in the inboard of this spring groove, lower chambers is isolated by valve piston and upper chamber, and locate in spring groove the lower end of spring.
So the advantage of design is to utilize valve piston with the lower chambers permanent closure of cylinder, and spring is moved on to the outside, spring do not contacted with the fluid of bottom chamber, thereby prevented effectively that so just spring from may influence the problem in fluid properties and spring service life with fluid generation chemical reaction.
On the basis of such scheme, thereby offset negative pressure in it for making extraneous air can enter cylinder, thereby be beneficial to the extruding repeatedly of nozzle, described cylinder is provided with deflation hole at the upper chamber place, big piston is in upper chamber and be positioned at this deflation hole place, and cylinder inner cavity is isolated from the outside.
Under normal condition, the deflation hole at upper chamber place is by big piston closes, cylinder inside not with extraneous UNICOM, keep air-tight state.
When gland is pressed down, because the space of the indoor big piston of upper chamber of air cylinder top enlarges gradually, and big piston leaves the position of deflation hole, air enters the upper chamber of air cylinder chamber and fills up outside shower nozzle, and since the lower sealing ring of choker relief valve seal mutually with the upper sealing ring of piston greatly, the air that enters can not enter downwards in the space of big piston below, and the interior original air of side space then will be squeezed into the choker relief valve inner chamber gradually under the big piston along with pressing down of gland, mix mutually with fluid.
After pressing the release gland that finishes, break away between the upper sealing ring of the lower sealing ring of choker relief valve and big piston, air in the big piston superjacent air space is in air passing hole enters down side space, the volume Zhu Jian Shrink of superjacent air space is little, the volume of following side space increases gradually, finishes air inerchange, final big piston reset, with the deflation hole shutoff, ready for press next time again.
In addition, between described cylinder upper limb and bottleneck, be provided with one deck packing ring, guarantee the air-tightness between cylinder and the bottleneck.
The invention has the beneficial effects as follows:
Foam nozzle of the present invention adopts three place's sealing mechanisms, under different conditions, diverse location is sealed, can guarantee again that in the leak tightness that guarantees foam nozzle inside air-flow enters smooth and easy when offsetting negative pressure, whole crumpling process is very light, liquid that can not leaks in the bottle, in addition, the foam of pressing formation is abundant, and feel is good.

Described check valve 13 is located at 1422 places, liquid inlet of 142 bottoms, lower chamber of air cylinder chamber.
Structural principle of the present invention is:
As shown in Figure 2, under normal condition, be full of fluid in the lower chambers 142 of cylinder, and be air in the upper chamber 141 of cylinder, the deflation hole 1411 of upper chamber 141 is by big piston 5 sealings, cylinder 14 inboards not with extraneous UNICOM, maintenance air-tight state;
At this moment, the lower sealing ring 431 of choker relief valve 4 is not nested with sealing with sealing 531 rings of going up of big piston 5, and pore 532 links upper and lower two parts space of being cut apart by big piston 5 in the upper chamber of air cylinder chamber 141.But, because sealing is replaced mutually with the lower seal inclined-plane 411 of big piston 5 in the sealing inclined-plane 721 of going up of adapter sleeve 7, therefore the gas in the upper chamber of air cylinder chamber 141 can not enter the inner chamber of choker relief valve 4, simultaneously, sealing is replaced mutually with the lower seal inclined-plane 811 of valve piston 8 in the sealing inclined-plane 93 of going up of needle-valve 9, so the fluid in the lower chamber of air cylinder chamber 142 can not enter the hollow channel 61 of connecting rod 6.
As shown in Figure 3, press down gland (approximately 2mm) slightly, thus cylinder 11 lower edges of gland 1 replace the shirt rim 43 of choker relief valve 4 and press down choker relief valve 4, but this moment big piston 5 and the position of valve piston 8 remain unchanged.The lower sealing ring 421 of choker relief valve 4 is nested with sealing mutually with the upper sealing ring 531 of big piston 5, makes two parts space of big piston about in the of 5 isolated.Because choker relief valve 4 is also replaced adapter sleeve 7 downwards simultaneously and is moved down, thus adapter sleeve 7 go up sealing inclined-plane 721 and big piston 5 lower seal inclined-plane 511 break away from, the air of big piston 5 belows can enter choker relief valve 4 in the upper chamber of air cylinder chamber 141; Simultaneously, downward promotion connecting rod 6 gone back by second screen cloth 41 of choker relief valve 4 and needle-valve 9 together moves down, thereby makes the lower seal inclined-plane of going up sealing inclined-plane 93 and valve piston 8 811 disengagings of needle-valve 9, and lower chamber of air cylinder chamber 142 interior fluids can enter the hollow channel 61 of connecting rod 6.
Spaces owing to big piston 5 tops in the upper chamber of air cylinder chamber 141 enlarge gradually in addition, and big piston 5 leaves the position of deflation hole 1411, air enters upper chamber of air cylinder chamber 141 and fills up outside shower nozzle, and since the lower sealing ring 421 of choker relief valve 4 seal mutually with the upper sealing ring 531 of piston 5 greatly, the air that enters can not enter in the space of big piston 5 belows downwards, original air then will be squeezed into choker relief valve 4 inner chambers gradually along with pressing down of gland in big 5 times side spaces of piston, mix mutually with fluid.
As shown in Figure 4, continue to press down gland 1 on earth, thus the lower sealing ring 421 of choker relief valve 4 replace the coupling link 53 of big piston 5 and press down big piston 5, thereby connecting rod 6 lower edges are also replaced the coupling link 83 of valve piston 8 and are pressed down valve piston 8.The space of big piston 5 belows is by Zhu Bu Ya Shrink in the upper chamber of air cylinder chamber 141, and gas constantly enters choker relief valve 4 inner chambers via the gas passage between choker relief valve 4 and the adapter sleeve 7; And the space in the lower chamber of air cylinder chamber 142 is also by Zhu Bu Ya Shrink, fluid constantly enters connecting rod 6 hollow channels 61 in choker relief valve 4 chambeies and connecting rod hollow channel 61 UNICOMs from the fluid passage of needle-valve 9 and valve piston 8 interior cylinders 81, in choker relief valve 4 inner chambers (perhaps also can in the hollow channel 61 of connecting rod), gas and fluid mix, form abundant foam through first screen cloth 21 on second screen cloth 41 on the choker relief valve 4 and the net plug 2 again, from runner 12 and the outlet ejection of gland 1.
Behind the ejection aequum, discharge gland, under the effect of spring 10 restoring forces, adapter sleeve 7 and choker relief valve 4 move up.In the upper chamber 141 of cylinder, sealing is replaced again mutually with the lower seal inclined-plane 511 of big piston 5 in the sealing inclined-plane 721 of going up of adapter sleeve 7, and the upper sealing ring 531 of the lower sealing ring 421 of choker relief valve 4 and big piston 5 breaks away from mutually, thereby pore 532 is opened, air progressively enters the space of big piston 5 belows by pore 532 from big piston 5 tops, big piston 5 is resetted.And in the lower chambers 142 of cylinder, the expansion neck 62 that adapter sleeve 7 promotes connecting rod 6 rises connecting rod 6 and needle-valve 9, sealing is replaced again mutually with the lower seal inclined-plane 811 of valve piston in the sealing inclined-plane 93 of going up of needle-valve 9, and the disk 92 of needle-valve 9 bottoms also will drive valve piston 8 risings and reset.
In addition, owing to break away between the upper sealing ring 531 of the lower sealing ring 421 of choker relief valve 4 and big piston 5, air in big piston 5 superjacent air spaces enters down in the side space through air passing hole 532, the volume Zhu Jian Shrink of superjacent air space is little, the volume of following side space increases gradually, finish air inerchange, final big piston 5 resets and with deflation hole 1411 shutoff, and is ready for press next time.
