Abstract

Disclosed is a mini inflator capable of being filled in pocket, which comprises a piston, a cylinder, a valve, an air inlet, an air outlet, a ball, a spring and a pipe nipple. The piston in the cylinder can move back and forth without air leakage. On the inner bottom of the cylinder, one half of the valve is fixed and the other half is unfixed. The half of the unfixed valve can close the air inlet and open the air outlet. A column at the end of the cylinder is sleeved with a shaped plastic pipe nipple. The ball and the spring are arranged in the pipe nipple and the ball arranged between the spring and the pipe nipple. When the piston is extracted, under a negative pressure in the cylinder, the ball blocks the air outlet with the spring tension, therefore the valve will automatically rise up to allow the air into the cylinder. When the piston is pressed, under the increased air pressure in the cylinder, the valve automatically resets and covers the air inlet and the ball overcomes the spring tension to automatically form a gap with the air outlet, the air in the cylinder is inflated from the pipe nipple to the inflated body through the gap.

Description

A kind of micro pump that can be contained in the pocket

Affiliated technical field

The utility model relates to a kind of inflator of giving Tyre inflating, especially gives the micro pump of inflations such as balloon, ball, basketball, football.

Background technique

Known at present, the general inflator description in market is few, and its structure is chewed etc. by piston, cylinder, valve, flexible pipe, gas and formed, and solves the inflation requirements of article such as tire substantially.But, most inflator volumes more heavily but also long carry inconvenience, particularly small-sized, the outstanding sense of random strong article inflation is not enough.

Summary of the invention

In order to overcome existing inflator volume greatly not only heavily but also longly carry inconvenient deficiency, it is a kind of small and exquisite, easy to carry that the utility model provides, and can be contained in the micro pump in the pocket.

The technological scheme that its technical problem that solves the utility model adopts is: the circular cylinder that adopts engineering plastics to make, there is the cylinder of band tapering the bottom surface of cylinder, porosely in the post communicate with cylinder, the cylinder next door also has an inlet hole also to communicate with cylinder, valve round plastic scraps of paper doubling, half is cemented on the cylinder inner bottom surface, second half can movablely also can cover inlet hole, the plastic tube that puts shaping on the cylinder of cylinder end is chewed again, spring and pellet shot from a slingshot in chewing, pipe are housed, pellet shot from a slingshot is mixed corresponding piston between spring and air outlet hole.When taking out outside the piston, form negative pressure in the cylinder, pellet shot from a slingshot stops up air outlet hole under the tension force of spring, the automatic perk of half meeting of valve this moment, and air enters cylinder from inlet hole, when piston is compressed into, inner pressure of air cylinder increases, and valve reset covers inlet hole, and pellet shot from a slingshot overcame spring tension and formed the gap automatically with air outlet hole this moment, air in the cylinder is through gap, air outlet hole, chewed to enter by pipe to be inflated object and to reach the inflation purpose.

The beneficial effects of the utility model are, and are big to flowability, random strong, and small article inflation that should be acute is provided convenience, and it is simple in structure, and is with low cost, realizes easily producing in batches.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

It shown in the figure erection drawing of the present utility model.

.1. piston among the figure, 2. cylinder, 3. valve, 4. inlet hole, 5. air outlet hole, 6. pellet shot from a slingshot, 7. spring, 8. pipe is chewed.

Embodiment

Among the figure, piston (1) is contained in cylinder (2) lining and can back and forth advances and retreat air tight, after valve (3) is the doubling of the round plastic scraps of paper, half is fixed on cylinder (2) inner bottom surface, second half is movable, active face can cover inlet hole (4) and get out of the way air outlet hole (5), pellet shot from a slingshot (6) spring (7) is contained in pipe and chews (8) lining and tightly be enclosed within on the cylinder of cylinder bottom again, because the tension ball (6) of spring (7) abuts against on the end face of air outlet hole (5), it also is inflator and the link that is inflated object that pipe is chewed (8), and optionally replaceable pipe is chewed.

Claims

1. micro pump that can be contained in the pocket, this inflator is by piston, cylinder, valve, inlet hole, pellet shot from a slingshot, spring, pipe is chewed composition, it is characterized in that: circular cylinder is made with engineering plastics, there is the cylinder of band awl the bottom surface, porosely in the post communicate with cylinder, post is other to also have inlet hole also to communicate with cylinder, valve round plastic scraps of paper doubling, half is cemented in the cylinder bottom surface, and half is movable and can cover inlet hole, the terminal cylinder of cylinder, the plastic tube that puts shaping is chewed, and spring and pellet shot from a slingshot are housed in pipe is chewed, and pellet shot from a slingshot is between spring and air outlet hole, mix corresponding piston, piston can back and forth be advanced and retreat air tight in cylinder.
