Abstract
The invention relates to a reciprocating elastic diaphragm pump which comprises a lead tube, a pump cylinder, an inlet and outlet check valve, an elastic membrane, a pressure rod, a cylinder opening plug and the like. The outer edge of the elastic membrane is arranged on a pump cylinder opening and fixed and sealed on the pump cylinder opening by the cylinder opening plug; the elastic membrane is extended inside the pump cylinder by the pressure rod, so the pressure inside the pump cylinder is boosted; the inlet and outlet check valve is opened or closed to discharge the liquid; the pressure rod is released and the elastic membrane resets to reduce the pressure inside the pump cylinder and absorb the liquid by opening or closing the inlet and outlet check valve. The elastic membrane replaces the functions of a piston of an original piston pump and a restoring spring so as to greatly reduce the height of the pump cylinder. According to the reciprocating elastic diaphragm pump, the defects caused by dynamic sealing of the piston are also overcome and the sealing requirements on the cylinder wall are reduced, so that the purpose of saving efforts is achieved. The reciprocating elastic diaphragm pump is short and small in size and can be arranged inside a nozzle. The metal spring also can be used together with the elastic membrane so as to improve the lateral force of the elastic membrane for resisting against the pump cylinder, improve resilience of the elastic membrane and accelerate the liquid suction speed.
Description
Technical field
The invention belongs to daily living article, mainly be installed on the bottle cap, pump through the beauty articles for use of pushing with hand aqua in the packing bottle or emulsion form.
Background technique
Existing shower pump or emulsion pump are named by its purposes or liquid form, and its structure is identical, all belong to reciprocating piston pump.The shower pump has been connected in the bottle cap, adds the good supply the market of skirt and showerhead configurations again, is general product, be widely used for many years, yet it but is inefficient, regardless of the use from stock utilization or strength.
By 3 milliliters of shower pumps in the streets buying, take apart to measure and draw: the connecting section of pumping cylinder top and bottle cap is high 7 millimeters, 10 millimeters of the import pipeline sections at the bottom of the pumping cylinder, and these two sections can be considered essential section; The pumping cylinder section is high 55 millimeters, and the lining has piston high 10 millimeters, and Returnning spring is high 45 millimeters, can be regarded as out in view of the above piston account for the pumping cylinder section high 18.2%, it is high by 71.8% that Returnning spring accounts for the pumping cylinder section; Calculating piston stroke again is 15 millimeters, is about 33% of Returnning spring length overall, and only is 27.3% with pumping cylinder section height finderheigt indicator, and the visible stroke ratio that is used for pump liquid is very low.
Pushing the shower pump also needs bigger power, and through measuring, be pressed into the stroke lowermost end liquid is discharged, with pushing the speed difference, the 2.5-2.8 kilogram of exerting oneself, pushing when not beating liquid needs 2.3 kilogram forces, and single Returnning spring of pressing is wanted the 1.3-1.5 kilogram force.Consumption is but only arranged the high 200-300 millimeter height of 3 milliliters of liquid to bottle so energetically, and energy efficiency is too low.
Piston needs strict seal to the pumping cylinder inwall, just must bring static friction and kinetic friction resistance, because pumping cylinder is longer; For the ease of depanning; Just need bigger withdrawing pattern slope, resistance advanced an increase when this just caused piston down to move, and reached maximum value to end of travel.Rough calculation draws about 1.8 kilograms of the frictional force that is used to overcome piston, has accounted for 64-72% with all strength.
Further investigate existing shower douch, the acting just connecting tube of transfusion, the space under the pushing surface does not but have utilization, and its volume is roughly suitable with bottle cap.Existing shower pump is because long, and it is installed in the shower nozzle will influence outward appearance widely, and only from the meaning of space utilization, and it is installed in the bottle cap and indistinction.It is that bottle connects lid band pump and abandoned entirely with shower nozzle that yet bottle uses up, and the shower pump is not the thing of cheapness, abandons unfortunately rather, therefore as if being loaded in the shower nozzle simultaneously usefulness again, has just once reclaimed two items, and bigger meaning was just arranged in today of promotion environmental protection.The problem of how to reduce the shower pump, and then design a more attractive appearance, in order to improve the recovery and collection of consumer desire.
There is a kind of rifle formula flit-gun in market, is contained in reciprocating pump in the shower nozzle, and volume is bigger, has used the plate machine of lever principle, pushes and also wants nearly 3 kilogram forces, trips out atomization spray cap, firmly also wants 2 kilograms.18 millimeters of opening cylinder diameters, 4 millimeters of piston strokes are through 0.96 milliliter of the average discharge opeing of actual measurement.Obviously volume and the lifting rate with regard to pump all can not be used to the pump of taking a shower.
Inventor's model utility and patent of invention in one's early years; The patent No. 93215052.7 " proportion expression liquid pump " and the patent No. 200310111947.1 " dystopy reciprocating pump and the hair dyeing comb with dystopy reciprocating pump " have all been used two piston pump structures; The greatest problem that the result runs into when commercialization is exactly that space availability ratio is too low, and requires great effort very much, and a particularly back invention is exerted all one's strength with finger; Use 5 kilograms power, operation almost can't be accomplished.Therefore, fundamentally solve the labour-saving problem and just should abandon reciprocating pump, remove production volumetric efficiency height and the inside wall of cylinder is not had frictional force or the little pump of frictional force.
Summary of the invention
In order to overcome the deficiency of existing shower reciprocating pump, the invention provides reciprocating type elasticity membrane pump, can improve the volumetric efficiency of pump, save raw material, laborsaving during use.
In order to achieve the above object, the present invention realizes through following technological method: reciprocating type elasticity membrane pump comprises: skirt 1, pumping cylinder 2, import one-way valve 3, elastic membrane 4, depression bar 5, outlet one-way valve 6, bottle cap 7, cylinder mouth plug 8, shower nozzle 9, seal ring 10 are formed.Bottle cap 7 is porose, outside the pumping cylinder 2 disk 2.1 is arranged, can be from bottle cap 7 lower end intercalations, and pumping cylinder mouth 2.2 stretches out bottle cap 7 becomes connecting section, and disk 2.1 overlaps with annulus at the bottom of its lid in bottle cap 7, fills in seal ring 10 in the annular space of pumping cylinder 2 and bottle cap 7; Import one-way valve 3 is set in the pumping cylinder; 4 one-tenth tubulars of elastic membrane, its oral area extension 4.2 places pumping cylinder mouth 2.2, and elastic membrane 4 is hung in the pumping cylinder 2; The base plate round mouth 5.1 and elastic membrane 4 bottom round mouths 4.1 tablings of depression bar 5 form sealing, and depression bar 5 base plate extensions 5.2 join together with elastic membrane 4 and the inwall of pumping cylinder 2 adapts, and outlet one-way valve 6 is arranged in depression bar 5 cavitys; Cylinder mouth plug 8 passes from the opening 5.3 of depression bar 5, and compressing pumping cylinder mouth 2.2 is with the 4.2 fixing and sealings of elastic membrane 4 oral area extensions, the fixedly connection of pumping cylinder 2 and bottle cap 7 simultaneously; Connect shower nozzle 9 on the opening 5.3 of depression bar 5; Skirt 1 inserts the pumping cylinder 2 bottom mouths of pipe 2.3.
There is balance aperture 2.4,7.1 relative on the annulus of pumping cylinder disk 2.1 and bottle cap 7; Both sides over against the seal ring 10 at two balance aperture centers add the edge of a knife; Just form unidirectional loose-leaf 10.1; When the internal drop of bottle was hanged down, the outer air of bottle was pushed unidirectional loose-leaf 10.1 open through balance aperture 7.1,2.4 and is got in the bottle; But can keep shut to the liquid in the bottle.For ease of installing, the three also should have positioning mark.
Relieving is pushed shower nozzle 9, and elastic membrane 4 will make pumping cylinder 2 internal drops low along casing wall generation resilience in pumping cylinder 2, imports and exports one- way valve 3,6 automatic on-off and liquid is sucked under the effect of pressure.
Find out thus: the function that the base plate of elastic membrane 4 and depression bar 5 has been replaced piston and Returnning spring, the following space of elastic membrane 4 and piston all only connect with outside through importing and exporting one-way valve; The resilience of elastic membrane 4 is also identical with the resilience of Returnning spring.Might as well be springform 4 and depression bar 5; Be envisioned for sealing film parcel " piston ", the sealing film mouth is fixed in pumping cylinder mouth 2.2, and the annular space that therefore is somebody's turn to do between " piston " and cylinder is an enclosed space to atmosphere all the time; Annular space just no longer needs sealing, and increasing stroke does not have difficulty yet; And reciprocating pump is just different, and piston needs to keep at the volley sealing, and another side is exactly an atmosphere; Annular space one has leakage, just destroys the negative pressure of pumping cylinder, and reciprocating pump is found time; And up increase the chance that stroke is found time increase, and down possible seized piston, only if strengthen Returnning spring.Just " dynamic seal (packing) " of piston bring the significant deficiency of reciprocating pump.
The bottom round mouth 4.1 of elastic membrane 4 is thicker, and chimeric favourable to form stable sealing to depression bar 5 round mouths 5.1 adds upper plate extension 5.2 and join together with elastic membrane 4, can prevent that air from getting into from the gap of elastic membrane 4 and depression bar 5, avoids finding time.
The base plate extension 5.2 of depression bar 5 is shorter with elastic membrane 4, has cancelled the Returnning spring that accounts for pumping cylinder section height 71.8% originally again, and the length of pumping cylinder 2 just significantly reduces, moreover Returnning spring or Stainless Steel Products, and is more favourable to reducing cost.
Reciprocating type elasticity membrane pump helps producing big lifting rate pump, if the extension of elastic membrane 4 the same with conventional piston be 10 millimeters, in elongation percentage 300%-400%, just can obtain the stroke of 30-40 millimeter with elastic membrane 4, this is that the twice of stroke of conventional shower pump is many.In fact some elastomer can also provide up to the elongation percentage more than 600%, just provides convenience for the reciprocating type membrane pump of bigger discharge capacity.Reciprocating type elasticity membrane pump is to be installed on pumping hole top, and the conventional shower pump of available sectional area ratio wants big, so lifting rate will further increase.
Pumping cylinder 2 is shorter, so pumping cylinder 2 can be once injection molded with bottle cap 7, and does not have thread with the bottle cap of bayonet socket connection bottleneck, helps reducing mould and assembly fee and uses.
Reciprocating type elasticity membrane pump comprises skirt 1, pumping cylinder 2, import one-way valve 3, elastic membrane 4, depression bar 5, outlet one-way valve 6, bottle cap 7, cylinder mouth plug 8, shower nozzle 9, seal ring 10 compositions.Pumping cylinder 2 is injection molded for once with bottle cap 8, and balance aperture 7.1 is arranged on the bottle cap 7, fills in seal ring 10 in the annular space, has unidirectional loose-leaf 10.1 relative with the center of balance aperture 7.1; The connecting relation of all the other each members is constant.
When the very big liquid of pumping viscosity or rate of pumping were very fast, liquid resistance was bigger, presses in the pumping cylinder 2 to increase, and the sidewall of elastic membrane 4 will receive the effect of liquid lateral force and indent reduces the liquid of discharge.Except that the resistance that improves export pipeline and outlet one-way valve, use harder elastic membrane or in elastic membrane 4, add the effect that spring just has the lateral force resisted.
The reciprocating type elasticity membrane pump that adds spring comprises skirt 1, pumping cylinder 2, import one-way valve 3, elastic membrane 4, depression bar 5, outlet one-way valve 6, bottle cap 7, cylinder mouth plug 8, shower nozzle 9, seal ring 10 and metal spring 11 compositions.Metal spring 11 has oral area extension 11.1, and 4 one-tenth tubulars of elastic membrane, metal spring 11 are inserted in the elastic membrane 4, and their oral area extension 4.2 and 11.1 places pumping cylinder mouth 2.2 simultaneously and fixes and sealing with cylinder mouth plug 8; The connecting relation of all the other each members is constant.
The effect that metal spring 11 itself has the lateral force resisted; Can extend synchronously and resilience with elastic membrane 4 again; Particularly use thinner line footpath, little pitch; Make elastic membrane elongation back wire still intensive, the film distance between two wires is very short, just more helps pining down the indent of film between two wires.Except metal spring 11 can also improve the rebound velocity of elastic membrane 4, accelerate suction to viscous liquid.Metal spring 11 places in the elastic membrane 4 and elastic membrane 4 height such as grade, does not therefore influence volumetric efficiency; Metal spring 11 is contact liq not, does not need to make with stainless steel.Fine and closely woven metal spring 11 can be packed into before elastic membrane 4 injection mouldings in the grinding tool, just can obtain the composite elastic mould 411 of metal spring 11 in elastic membrane 4, and it has bottom round mouth 411.1, oral area extension 411.2.
Further again; Can reciprocating type elasticity membrane pump be packed in the shower nozzle 9, because of the sectional area and the bottle cap of general shower nozzle are suitable, and some external form shower nozzle 9 preferably; Nozzle 9.1 has all been covered; Pushing surface no longer is simple circle, and the area that can be used for being provided with reciprocating type elasticity membrane pump is just bigger, because can design the sectional shape of pumping cylinder according to the pushing surface of shower nozzle.
The reciprocating type elasticity membrane pump that is installed in the shower nozzle comprises: pumping cylinder 2, import one-way valve 3, elastic membrane 4, depression bar 5, outlet one-way valve 6, cylinder mouth plug 8, shower nozzle 9, metal spring 11 are formed; Elastic membrane 4 is injection molded into one with metal spring 11, has become composite elastic mould 411; Pumping cylinder 2 is once injection molded with shower nozzle 9, and nozzle 9.1 its inlet ducts of shower nozzle 9 are in the bottom of pumping cylinder 2, installation outlet one-way valve 6 in the outer pipe; The oral area extension 411.2 of composite elastic film 411 places pumping cylinder mouth 2.2; The base plate round mouth 5.1 and composite elastic film 411 bottom round mouths 411.1 tablings of depression bar 5 form sealing, and the base plate extension 5.2 and the composite elastic film 411 of depression bar 5 joins together and the inwall of pumping cylinder 2 adapts; Cylinder mouth plug 8 passes from the opening 5.3 of depression bar 5, and compressing pumping cylinder mouth 2.2 is with the extension 411.2 fixing and sealings of composite elastic film 411; In depression bar 5 cavitys import one-way valve 3 is arranged, the opening 5.3 of depression bar 5 is exactly the import of shower nozzle 9.
Bottle cap no longer is the layout structure of shower nozzle 9, below only is the connecting relation of narration and bottle cap: bottle cap 7 is outer to have outer pipe 7.2, has in the lid and takes over 7.3, and skirt 1 inserts in the adapter 7.3.The outer pipe 7.2 of the opening 5.3 insertion bottle caps 7 of depression bar 5, shower nozzle just can use.
Also more reasonable from the configuration of market, no longer supporting skirt 1 of shower nozzle 9 and bottle cap 7, because the length of skirt is to cooperate the bottle height, the internal diameter of bottle cap 7 and seal ring 10 is to cooperate the bottleneck external diameter.
Further,, just become the comb of ability pump liquid, pushed to comb one's hair with hand and just can pump liquid between the broach of combing one's hair if add upper comb dent all around the prolongation of the pushing surface of shower nozzle 9 and at nozzle 9.1.
As doing identical improvement, just can be used for the identical Comb structure for dyeing hair of this patent of invention with reference to the structure of patent of invention 200310111947.1 " dystopy reciprocating pump and hair dyeing comb " with dystopy reciprocating pump.
Further again, because laborsaving more good more viewpoint can not all be admitted in market, some crowd's inertia cognition possibly too gently feel not get used to pushing, and therefore also can design and push heavier product.Select harder elastic material or with powerful metal spring just can production Different Weight grade product, also more favourable to the indent that solves springform in view of the above with the speed of accelerating imbibition.
Also can designing outer wall in elastic membrane 4, several ring cross-sections are arranged is the annular bead of hemisphere; Interannular is a thin-walled, and with respect to depression bar base plate extension 5.2 places, the hemisphere diameter of annular bead is bigger; So that strengthen the effect that the pressure of pumping cylinder 2 inwalls is formed similar O circle; Just can realize strengthening friction, increase scurrying into the liquid resistance of annular space between film and wall, favourable to further minimizing elastic membrane 4 indents.Strengthen the hemisphere diameter again, the pressure that strengthens pumping cylinder 2 inwalls just has been tantamount to the resistance of reciprocating pump, but if need also not have can not market have.
Minimizing elastic membrane 4 indents comprehensively each technological enforcement solve, and should be prepreerence but select bigger depression bar 5 internal diameters for use, because of the cost minimum that increases; Next is with the little one-way valve of resistance.
Membrane pump is arranged in the industry, but its principle is different, is to make the barrier film to-and-fro motion by motor or other actuating mechanisms, therefore is diaphragm pump again.The film of diaphragm pump is only for insulating effect, avoids harmful suspended matter or chemicals in the liquid to the erosion of member.In the 10th phase of " aero-manufacturing technology " nineteen eighty-two " application of reciprocating type membrane pump on the coating automatic control line " literary composition, described membrane pump be pneumatically promote piston make 130 automobile brake drum rubber left and expansion to the right carry coating.Itself just has bulging face brake drum rubber, and expanding left and to the right is that piston rod makes bulging face protrusion and depression in fact; Single also push away the spherical drum face of can not pull with piston rod.
