Abstract

The utility model discloses a manual operation sucking pump, which comprises a cylinder barrel and an air exhaust plunger arranged in the cylinder barrel, wherein the section of an end cover of the air exhaust plunger, which is exposed out of the cylinder barrel, is elliptical, handle grooves concaving inwards are arranged on two sides of the end cover, outwards extending circular bulge rings are arranged on the edge of the lower end of the end cover and a peripheral barrel body of the cylinder barrel, and the two circular bulge rings are in contact when in a closed state; the caliber of an air suction hole in the lower end of the cylinder barrel is equal to the barrel diameter of the cylinder barrel, and a sealing sleeve is sleeved on the air suction hole.

Description

Manual suction pump

Technical field

The utility model relates to a kind of manual suction pump, particularly a kind of manual suction pump that is applied to vacuum bag.

Background technique

Vacuum bag is that air is less or almost do not have the bag that is used to deposit article of air in the bag, and food is placed in the vacuum bag can prolong fresh keeping time, can be compressed between its duty product when quilt clothes etc. are placed with vacuum bag to diminish; Vacuum bag all can be joined an extraction pump in the market; It also can be electronic that this air pump has manual, and the exhaust port facing to vacuum bag during use is bled, and air in the bag is taken out to the greatest extent get final product; This is just very convenient when using electronic extraction pump; But electronic extraction pump is heavy, uses and also will plug electricity, and is cumbersome.

Existing manual suction pump does not need electricity consumption, and the more electronic extraction pump of volume is little, and it comprises cylinder barrel and is arranged on the piston composition of bleeding in the cylinder barrel; The end cap that its piston of bleeding exposes cylinder barrel is a handle that lifts that has in-line; Lifting drawing piston very convenient of in-line, but just seem a bit trouble during toward back pressure generally takes that forefinger, middle finger and the third finger, little finger bifurcated are lifting a both sides when lifting; Thumb is pressed in and lifts on the end face; The hand of work done can be gruelling after the to-and-fro motion of doing repeatedly, and extraction pump cylinder barrel lower end intakeport is less, and pull gets up very heavy.

Summary of the invention

Sign in this, the purpose of the utility model is exactly that a kind of manual suction pump is provided for the deficiency that addresses the above problem.

The utility model the scheme that will deal with problems following:

Said a kind of manual suction pump; Comprise cylinder barrel and be arranged on the piston of bleeding in the cylinder barrel; It is characterized in that: the end cap cross section that the said piston of bleeding exposes cylinder barrel is provided with recessed to the inside handle groove for oval in the end cap both sides, at edge, end cap lower end and the peripheral cylindrical shell of cylinder barrel be provided with the boss ring that extends laterally; When closed state, two boss rings contact; Said cylinder barrel lower end intakeport bore is identical with the cylinder barrel barrel dliameter, is with stuffing box gland on it.

The beneficial effect of the utility model is following:

Compared with prior art, adopt the manual suction pump of the utility model structure, its end cap cross section is oval; Pull gets up very convenient, to the no requirement (NR) of putting of finger, points nature generally speaking and holds with a firm grip; Can hand can be not painstaking after the continuous pull, can increase user's endurance.

Compared with prior art, adopt the manual suction pump of the utility model structure, its cylinder barrel lower end intakeport bore is identical with the cylinder barrel barrel dliameter, and the inspiratory effects during pull is obvious, no sense of heaviness,

Description of drawings:

Fig. 1 is the structural representation of the utility model manual suction pump.

Among the figure: 1, cylinder barrel; 2, the piston of bleeding;

3, end cap; 4, handle groove;

5, boss ring; 6, intakeport;

7, stuffing box gland.

Embodiment:

Below in conjunction with accompanying drawing the utility model is done further detailed elaboration.

Consult Fig. 1; Manual suction pump comprises cylinder barrel 1 and is arranged on the piston 2 of bleeding in the cylinder barrel 1, and the said piston 2 of bleeding exposes end cap 3 cross sections of cylinder barrel 1 for oval; Be provided with recessed to the inside handle groove 4 in end cap 3 both sides; At end cap edge, 3 lower end and cylinder barrel 1 peripheral cylindrical shell be provided with laterally the boss ring 5 that extends, when closed state, two boss rings 5 contact; Said cylinder barrel 1 lower end intakeport 6 bores are identical with cylinder barrel 1 barrel dliameter, are with stuffing box gland 7 on it.

During use, facing to the outlet valve above the vacuum bag, described outlet valve is a flat membrane formula one-way valve structures with cylinder barrel 1 lower end intakeport 5; Be with stuffing box gland 6 for this reason on the intakeport 5 and can well play an effect of connecting airtight mutually with outlet valve; With the hand end cap 3 of holding with a firm grip naturally, the part skin of its hand can lean against on the handle groove 4, and handle groove 4 has played an anti-skidding effect; So when pull; Just can play a labour-saving effect again fast, its end cap edge, 3 lower end and cylinder barrel 1 peripheral cylindrical shell are provided with the boss ring 4 that extends laterally and can impinging upon together in the pull fast, can play an effect of showing clearly and extenuate momentum effect.

Claims

1. manual suction pump; Comprise cylinder barrel and be arranged on the piston of bleeding in the cylinder barrel; It is characterized in that: the end cap cross section that the said piston of bleeding exposes cylinder barrel is provided with recessed to the inside handle groove for oval in the end cap both sides, at edge, end cap lower end and the peripheral cylindrical shell of cylinder barrel be provided with the boss ring that extends laterally; When closed state, two boss rings contact; Said cylinder barrel lower end intakeport bore is identical with the cylinder barrel barrel dliameter, is with stuffing box gland on it.
