Abstract
The utility model relates to the field of liquid pressure pump devices for daily use, in particular to a liquid pressure pump, and aims to avoid leakage caused by internal pressure action of a container and prevent external water from flowing back to mix with a liquid inside the liquid container during use. The liquid pressure pump comprises an elbow, a backflow prevention ball, a combination cover, a gasket, a threaded ring, a piston rod, a piston, a piston seat, a spring, a negative pressure ball, a pump body and a suction pipe, wherein the piston, the piston rod and the combination cover are embedded in the piston seat and firmly pressed through the elbow, the negative pressure ball and the spring are placed in the pump body, and the elbow assembly is then pressed on the pump body assembly. The utility model has the advantages of simple structure and reasonable design, and is suitable for popularization and application.
Description
Technical field
The utility model relates to daily liquid press pump apparatus field, and what be specifically related to is a kind of liquid press pump.
Background technology
The liquid press pump, as a kind of dispensing apparatus of liquid simply and effectively, be widely used in shampoo, field such as hand cleanser and liquid soap, for people bring a lot of convenient and swift, its principle of work is pumping by elbow, for increasing air pressure in the liquid container, thereby liquid in the liquid container is extruded, and still, traditional liquid press pump in use, often leak between elbow and the screw collar because of the container internal pressure effect, and because of its use be the structure of independent counterseal pearl, in use be easy to take place outside moisture and reflux, invade in the liquid in the liquid container.
The utility model content
In order to overcome existing liquid press pump in use, often leak between elbow and the screw collar because of the container internal pressure effect, and because of its use is the structure of independent counterseal pearl, in use being easy to take place outside moisture refluxes, invade the medium deficiency of liquid in the liquid container, the purpose of this utility model is: a kind of liquid press pump is provided, can not leak because of the container internal pressure effect, and outside moisture in use can not take place reflux, invade in the liquid in the liquid container.
The technical scheme that its technical matters that solves the utility model adopts is as follows: the use that links together of a kind of liquid press pump, it and liquid container; It comprises elbow, the counterseal pearl, combining cover, pad, screw collar, piston rod, piston, piston seat, spring, the negative pressure pearl, the pump housing, suction pipe, the described pump housing is the hollow columnar body structure, spring is positioned at pump housing inside, piston is installed in spring top, piston head is installed piston seat, piston rod is positioned at the piston seat top, the counterseal pearl is installed on the piston rod top, screw collar are inner threaded ring bodies, be socketed on pump housing tip exterior by the outside, pad is positioned at screw collar and pump housing connecting portion inboard, elbow is the circular cover-shaped body that there is pore the side, is covered in the piston rod top, and combining cover is socketed in position between screw collar and the elbow, suction pipe inserts the pump housing by the below, and the negative pressure pearl is installed in the suction pipe top.
Described elbow can have square cover-shaped body, prismatic cover-shaped body or the oval cover-shaped body of pore for the side.
The assembling mode of present technique is
1, piston, piston rod, combining cover are inserted in piston seat, fasten with elbow;
2, negative pressure pearl, spring are put into the pump housing;
3, again the elbow assembly is pressed on the pump assembly.
The principle of work of present technique:
1, press down elbow, drive piston rod and move downward, piston separates with piston seat;
2, continue to press down, pipe link promotes piston and moves downward;
3,, make liquid upwards flow, through the ejection of elbow hole by the mesopore of piston and piston seat because pump housing end opening has the negative pressure bead seal to live, and piston moves down, and the space reduces, and air pressure increases;
4, head press down cancellation, recoil of spring drives piston rod and moves up, the gap sealing of piston and piston seat continues the drive piston and moves up;
5, make the interior space of the pump housing increase, air pressure reduces, and liquid suction passage in the bottle is washed the counterseal pearl open, flows in the pump housing;
6, a bottle internal gas pressure can be worked as elbow when pressing down, and by pump housing top aperture return-air, obtains external and internal pressure.
Beneficial effect
1, the utility model in use because the pump housing and conduit be all in liquid container inside, and can not produce difference of pressure between the screw collar, thereby has prevented the leakage of internal liquid;
2, the elbow inner tip is equipped with the counterseal pearl, in the process that head resets, has closed pump housing inside and has been connected with press pump is exterior, exterior water can't be soaked drain in the liquid.
