Description
Technical field
The utility model relates to a kind of external spring emulsion pump, belongs to the container filling field, is usually used in the container of bath article, articles for washing, cosmetics, food etc.
Background technique
The emulsion pump generally is mounted in the opening of container, is used for the manual pressing operation by the user, the liquid in the container is pumped, for use.Emulsion pump of the prior art generally is the structure that spring is set above glass bead, by the cooperation of spring and other parts, the control glass bead is up and down, thereby carries out the pump pressure of liquid.
Disclose a kind of emulsion pump as Fig. 2 Chinese patent 02226066.8, comprised head, last bead, principal post, big thread lock, thread, piston, subpost, spring, body, following bead and suction pipe; It is characterized in that on intrinsic top the secondary locked cock that one external diameter and body internal diameter are slidingly matched being set, secondary locked cock center has the through hole that is slidingly matched with the principal post external diameter; Secondary locked cock is blocked the air-vent on the body before head and big thread lock separate, and head separates afterwards with big thread lock that principal post makes progress jack-up with secondary locked cock and the air-vent on the body is opened.
Such emulsion pump makes spring be corroded because spring can contact with liquid, and liquid is contaminated.
Under the situation of emulsion pump ejection, some need reach spray effect, for having spray effect preferably, need a bigger interior pressure arranged from begin to be sprayed onto the overall process that stops to spray, and the big more spray effect of interior pressure is good more.In existing atomizing pump, when adopting the last one-way valve of forming by piston, piston head and connecting duct, above piston, install a little spring additional.When interior pressure hour, little spring is pushed down piston and one-way valve can not be opened.When interior pressure reached some numerical value, the active force that piston overcomes little spring moved and makes one-way valve opens, so just can spray preferably.But this atomizing pump exists complex structure, the demanding defective of element precision.
The model utility content
Spring takes place easily be corroded in order to overcome existing emulsion pump, liquid is contaminated, and complex structure, element precision requires high deficiency, a purpose of the present utility model is: provide a kind of simple in structure, durable, the less demanding external spring emulsion pump of element precision.
The technological scheme that its technical problem that solves the utility model adopts is as follows: a kind of external spring emulsion pump comprises head, connecting rod, spring, piston, the pump housing, ball float, suction pipe; Described spring is positioned at outside the connecting rod.
Also comprise piston rod, described piston rod is nested in the connecting rod, and the piston rod outer wall contacts with the connecting rod inwall.
Also comprise combining cover, the inboard groove that forms in described combining cover middle part, the ring that this groove becomes is nested in outside the connecting rod bottom, and extend downwards the trench portions bottom that contacts with connecting rod, and forming longitudinal section is the ring of wedge shape.
Described connecting rod top has the card arm.The card arm is stretched for slightly outwards putting down, and is converted into the structure at right angle under the outer end.
Described spring top nested is fixed by the card arm of connecting rod outside connecting rod, and the spring bottom nested is in the groove of combining cover.
Described piston top is the structure that has wedge slot, and this wedge slot cooperates just with the wedge shape of combining cover bottom.
Described piston rod outer wall has the groove that caves in, and the connecting rod inwall has projection, and the projection of groove on the piston rod and extension bar inwall cooperates just.
Described pump housing bottom is interior gradually receives, and receiving portions has deck in the beginning, also comprises sealing gasket, and described sealing gasket is positioned on the deck of ball float top under the pump housing.
Also comprise pad, the fillet of screw, described pad is between the combining cover and the fillet of screw.
Compared with prior art, the beneficial effects of the utility model are: the external spring, and can avoid liquid to contact with metalwork, prevent that liquid is contaminated by heavy metals, simple in structure, easy for installation, the powerful ejection of pressure is effective.
The leakage gas leak phenomenon adopts unique combining cover and piston structure, makes to cooperate between each parts better that the accuracy of parts requires low, owing to cooperation science between each parts can not take place.
Description of drawings
Fig. 1 is first embodiment's of the external spring emulsion of the utility model pump a structural representation;
Fig. 2 is prior art emulsion pump structure figure.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified, but not as to qualification of the present utility model.
See also the embodiment of the external spring emulsion of the utility model shown in Figure 1 pump.
A kind of external spring emulsion pump comprises cover 1, head 2, connecting rod 3, spring 4, piston 8, the pump housing 10, ball float 12, suction pipe 13; Described spring 4 is positioned at outside the connecting rod 3.
Also comprise piston rod 5, described piston rod 5 is nested in the connecting rod 3, and piston rod 5 outer walls contact with connecting rod 3 inwalls.
Also comprise combining cover 6, the inboard groove that forms in described combining cover 6 middle parts, the ring that this groove becomes is nested in outside connecting rod 3 bottoms, and extend downwards the trench portions bottom that contacts with connecting rod 3, and forming longitudinal section is the ring of wedge shape.
Described connecting rod 3 tops have the card arm.The card arm is stretched for slightly outwards putting down, and is converted into the structure at right angle under the outer end.
Described spring 4 top nested are fixed by the card arm of connecting rod 3 outside connecting rod 3, and spring 4 bottom nested are in the groove of combining cover 6.
Described piston 8 tops are the structure that has wedge slot, and this wedge slot cooperates just with the wedge shape of combining cover 6 bottoms.
