Background technique

Low dose of discharging hand pump is approximately each 0.2 milliliter hand pump of a kind of emission index, and can be used for filling liquid or emulsion at container by aspirating quantitative discharging.This pump is widely used in cosmetics containers and the analog owing to its facility.

Fig. 1 is the representative example that shows traditional low dose discharging hand pump.Traditional pump comprises: cylinder blanket (20), the outer surface of formation pump; Axle (30) wherein has fluid passage; Cylindrical piston (40) is along the internal surface to-and-fro motion of shell (20); Outer housing cover (25), set casing (20) and cover cap (not shown) be the to-and-fro motion of leading axle (20) simultaneously; Conical axle bed (32) is fixed on the lower end of axle (30); Upper springs (52) places piston (40) upper end; Lower springs (54) is installed on the conical axle bed (32); Ball (60) places the bottom of shell (20); And manage (80), be fixed on the lower end of shell and analog.This pump wherein has spiral fluted cover cap (not shown) with utilization and is fixed on the container that has filled solution.

The elastic force of upper springs (52) is greater than lower springs (54), make when downward masterpiece is used on the axle (30), the lower springs (54) that cooperates with conical axle bed (32) is compressed, the lower ends downward of piston internal surface (42) moves, simultaneously because the expansionary force of upper springs (52), the lower end on surface (42) and the cooperation of the upper end bead (33) of conical axle bed (32).When the lower end of the outer surface (44) of piston arrives the bottom of the less shell (20) of diameter, piston (40) no longer moves downward, and axle (30) continues to move down, upper springs (52) is compressed simultaneously, makes the lower end of piston internal surface (42) separate with the upper end bead (33) of conical axle bed (32).At this moment, import the lower end of inward faces (42) and the interval between bead (33) upper end, pass inflow entrance (36) then and enter inner passage (38) at the solution of cylindrical body inner space (22) pressurized.

When elimination axle (30) was gone up downward power, axle (30) moved upward, and upper springs (52) is extended the interval between the upper end bead (33) of the lower end of closed piston internal surface (42) and conical axle bed (32) at once simultaneously.At this moment, because the expansionary force of upper end spring (54) when moving up, the pressure of cylindrical internal surface (22) reduces when axle (30), and for the reduction of supplementary pressure, and when the ball (60) of outer casing underpart when upwards rising, solution flows into by pipe (80).

This traditional pump needs two springs.Wherein, upper springs (52) places the top of piston (40) to make when spool (30) when moving up and down, piston (40) and conical axle bed (32) cooperate, therefore spring (52) makes solution in the cylindrical body inner space (22) at axle (30) pressurized when moving downward, and reduces pressure when moving upward at axle (30).

Described outer housing cover (25) makes the top of shell seal and axle (30) is fixed in the shell (20) when the to-and-fro motion of leading axle (30).

In this, upper springs (52) and outer housing cover (25) are that traditional low dose is discharged indispensable parts in the hand pump.Yet, in undersized hand pump, because the complexity of installing and operating a plurality of parts very likely causes mechanical failure and improves manufacture cost.

Consider in addition and use and outward appearance that for the pump that is installed in container top, because preferably it accounts for the as far as possible little volume of entire container, constituting the size of the parts of pump must be littler and need accurate structure, manufacture process is difficult.And the article that the Consumer requires are many more, and the number that constitutes the parts of pump trends towards increasing manyly more.Therefore, use pump during the probability of faulty operation because the increase of parts also becomes more and more.

Therefore, an object of the present invention is to solve these problems of conventional art.More specifically, the objective of the invention is,, do not need upper springs just can finish the original function of pump by changing the axle and the structure of piston of the approximately each 0.2 milliliter conventional manual pump of emission index.

In addition, further purpose of the present invention is: by integrated outer housing cover and cover cap etc., and change its structure so that these parts are finished further function, thereby reduce whole parts number, simplify manufacture process, reduce the probability of faulty operation and finish the improvement function further.

Summary of the invention

For reaching these purposes, the approximately each 0.2 milliliter low dose discharging hand pump of suction emission index of the present invention is characterised in that this pump comprises:

Cylinder blanket, the outer surface of formation pump; Axle, the conical axle bed that wherein has fluid passage and axle lower end is linked to be an integral body; Cylindrical piston is along the internal surface to-and-fro motion of shell; Outer housing cover, fixedly the shell in the cover cap guides the to-and-fro motion of described axle simultaneously; Spring is installed in the lower end of described conical axle bed; Ball places the lower end of shell; The pipe, be fixed on shell the lower end; And cover cap, wherein have spiral chute and described outer housing cover and analog and be fixed together;

Wherein, axle contact with the piston internal surface and the length of the appropriate section of adjacency is longer than the length of the internal surface of piston, and this part has relatively little diameter with in described internal surface slip; And

Embodiment

Below explanation illustrates in greater detail the present invention with reference to accompanying drawing, yet scope of the present invention is not thought limitation of the present invention.

Fig. 2 is to low dose discharging hand pump and the component part thereof of Fig. 6 demonstration according to the different examples of the present invention.Following with reference to description of drawings according to pump structure of the present invention and running principle.

With reference to Fig. 4, the upper end with axle (30) of inner passage (38) is fixed on the starter (10), and spring (50) is contained on the conical axle bed (32) of lower end of axle (30).When on starter (10), acting on and eliminating downward power, has dual structure, the piston (40) of comprise internal surface (42) and outer surface (44) is along the internal surface to-and-fro motion smoothly of shell (20).

The part of the axle (30) that the to-and-fro motion of piston internal surface is slipped over refers to the part between the upper end bead (33) of right angle step (34) and conical axle bed (32).The diameter of these parts is less than other parts.The length of piston internal surface (42) is compared relative shorter with described part.In these parts, the sliding parts (31) of axle refer to when downward power when starter (10) and the part of internal surface (42) adjacency of piston, make that the internal surface to piston provides frictional force in to-and-fro motion.

According to one embodiment of the present of invention, because the area of the sliding parts (31) of the internal surface (42) of piston and axle adjacency is less than the outer surface (44) of piston and the area of the abutment of shell, the frictional force of (44) is greater than piston internal surface (42) reciprocating frictional force in piston (40) on the outer surface of piston.

Therefore, when downward masterpiece is used in when being used to aspirate on the starter, axle (30) moves down, and sliding parts (31) at first slides along the internal surface (42) of the less relatively piston of frictional force.When the upper end of the internal surface (42) of piston arrives the right angle step (34) of axle (30), slip stops, in this process, separate with the upper end bead (33) of conical axle bed (32) lower end of internal surface (42), and the solution of cylindrical body inner space (22) passes inflow entrance (36) by the gap of separating and imports inner passage (38).

Next step, along with axle (30) continues to move downward, the outer surface of piston (44) slides along the internal surface of shell (20), when the outer surface (44) of piston arrive shell (20) stop step (24) time, slip stops.

In addition, finish when suction, act on the pressure of axle on (30) and eliminate, axle (30) begins to move upward, this moment frictional force also the internal surface of less relatively piston (42) slide earlier than the outer surface (44) of piston.Therefore, the upper end bead (33) of the conical axle bed (32) by axle (30) cooperates with the lower end of the internal surface (42) of piston, intercepts the inner passage (38) of cylindrical inner space (22) and axle (30).Then, in the process that axle (30) continues to move upward, the outer surface of piston (44) slippage, the pressure of the inner space of containment cylinder (22) continues to reduce.Reduce for replenishing this pressure, ball (60) a little upwards rises, and blocks the lower curtate of shell with gravity, and the solution in the container imports inner space (22) by pipe (80) at interval by this.

Fig. 3 shows that wherein, interior cylindrical curved section (72) comprising according to the vertical sectional view of the cover cap of the another example of the present invention: first circumferential section (76), and its horizontal component from cover cap (70) (74) extends downwards; Second circumferential section (78) separates with first circumferential section (76) on the direction of central shaft; And attachment portion (77), it interconnects the lower end of the circumferential section of winning (76) and the lower end of second circumferential section (78), and forms circumferential groove (79) at its top.

Attachment portion (77) preferred construction is to be close to piston (40), owing to do not having downward masterpiece to be used for that attachment portion (77) cooperates with piston (40) under the state of starter (10), and the inside of obstruct shell (20) and the outside of shell.

The upper end of shell (20) is fixed on the space that is made of vertical component in the internal structure of cover cap (70) (73) and first circumferential section (76), because the bending force of the warp architecture of cylindrical curved section (72), retention force is improved.More specifically, second circumferential section (78) by with axle (30) adjacency, extrusion interior cylindrical curved section (72), the reaction force of this pressure-display for being caused by circumferential groove (79) etc. especially herein, this elastic reactance have been strengthened the retention force between the internal structure of the upper end of shell (20) and cover cap (70).

Fig. 4 to Fig. 6 has shown the various examples with two characteristics of the present invention.

Fig. 4 is an example that shows according to pump of the present invention (200), and total is except cover cap (70) and interior cylindrical curved section (72) integrate, and is identical with the pump (100) of Fig. 2.Compared to Figure 1 as seen, interior cylindrical curved section (72) is finished the function of outer housing cover (25), but not has outer housing cover (25).In assembly process, as long as the assembling of shell (20) and cover cap (70) can be finished in the top that cover cap (70) is installed to shell (20), so assembly process is very simple.

Fig. 5 is an example that shows according to pump of the present invention (300), and is the floss hole (12) that this structure is fixed on starter (10) except discharge nozzle (16) is gone up, identical with Fig. 4.

Fig. 6 is an example that shows according to pump of the present invention (400), and this structure is except nozzle (14) is fixed in the floss hole (12) of starter (10), and is identical with Fig. 4.Although the pump (200,300) of the overall structure of the pump of Fig. 6 (400) and Fig. 4 and Fig. 5 is identical, pump (400) might spray the low-viscosity (mobile) liquid that comprises little water droplet by the nozzle (14) that is installed in the floss hole (12).

More than describe the present invention, obviously the present invention can have multiple mode to change, and these variations are not considered to break away from the spirit and scope of the present invention, and all such changes are conspicuous for the personnel of art technology.
