Abstract

The utility model relates to a bidirectional inflator which belongs to a household article field. The utility model is provided with elementary structure parts of a common inflator. The difference is in that a group of one-way inspiration valves (7) or (10) and one-way exhaust valves (8) or (11) which are communicated with a cylinder chamber (4) and are mutually corresponding to the cylinder chamber are respectively arranged on a left cylinder cover, a right cylinder cover and end seats (6) and (9) of the utility model. Exhaust port channels (12) and (13) of the one-way exhaust valves (8) and (11) are all communicated with an inflation tube (5). The utility model has the advantages that the utility model can inflate in two directions, the internal energy of the cylinder chambers (4) of both sides of a piston (1) alternately, respectively and solely completes inward inspiration and outward inflation when the piston (1) is moved in a reciprocating mode. The whole inspiration process or the inflating process is continuously and simultaneously carried out. The utility model has the advantages of short inflation time, high efficiency, convenient fabrication and convenient use and maintenance.

Description

The bidirectional inflating tube

The invention belongs to the daily necessities field, relate to a kind of bidirectional inflating tube.

In the prior art, inflator pump substantially all is unidirectional gas-filled type, be that the inflator pump piston is just when a certain fixed-direction moves, just can finish external inflation, air-breathing and external inflation itself is all carried out in that the cylinder of piston the same side is indoor, therefore externally inflation is still own air-breathing all is alternately to be interrupted to carry out, and inflationtime is long, and efficient is low.

The objective of the invention is to, a kind of bidirectional inflating tube is provided, but bidirectional inflating, when being the inflator pump reciprocating motion of the pistons, the cylinder chamber of piston both sides can replace finishes inwardly air-breathing and external inflation respectively separately, and whole air-breathing or external gas replenishment process is successively and carries out simultaneously, thereby inflationtime is short, the efficient height, and make simply, working service is convenient.

Concrete scheme of the present invention is as follows:

Bidirectional inflating tube 1, the cylinder chamber 4 that has piston 1, piston rod 2, cylinder barrel 3 and hold concurrently and hold seat to form with cylinder cap, and gas tube 5 and other attached parts that help, it is characterized in that: left cylinder cap is held concurrently to hold on the seat 6 one-way sucting valve 7 and the one-way exhaust valve 8 that is communicated with cylinder chamber 4 is housed respectively, and right cylinder cap is held concurrently to hold on the seat 9 one-way sucting valve 10 and the one-way exhaust valve 11 that is communicated with cylinder chamber 4 is housed respectively; One-way exhaust valve 8 and 11

exhaust stomatodeum

12 and 13 all are communicated with gas tube 5.

Usefulness of the present invention is: but the inflator pump bidirectional inflating, when being 1 to-and-fro motion of inflator pump piston, the cylinder chamber 4 of its both sides can replace finishes inwardly air-breathing and external inflation respectively separately, whole air-breathing or external gas replenishment process is successively and carries out simultaneously, thereby inflationtime is short, the efficient height, and make simply, working service is convenient.

Accompanying drawing 1, general assembly structural drawing;

Accompanying drawing 2, one-way sucting

valve

7 and 10 or the mounting structure figure of one-way exhaust valve 8 and 11;

Embodiment: further explanation in detail in conjunction with the accompanying drawings.

Each one-way sucting valve or one-way exhaust valve are communicated with associated components by corresponding air-breathing stomatodeum and exhaust stomatodeum respectively, gas tube 5 is connected on the double end seat 6 of left cylinder cap, and be communicated with the exhaust stomatodeum 12 of one-way exhaust valve 8, right cylinder cap hold concurrently the exhaust stomatodeum 13 of the one-way exhaust valve 11 on the end seat 9 by air pipe 14 through with after the exhaust stomatodeum 12 of one-way exhaust valve 8 is communicated with, be communicated with gas tube 5; The two ends of air pipe 14 are connected on respectively on the

double end seat

6 and 9 of left and right cylinder cap.

One-way sucting

valve

7 and 10 or the mounting structure of one-way exhaust valve 8 and 11 as follows: have valve block 15, its air-breathing oral-lateral is equipped with sealing gasket 16, its opposite side is equipped with stage clip 17, is fixed on by gland nut 18 in the corresponding valve pocket 19 of the

double end seat

6 and 9 of left and right cylinder cap.

" O " RunddichtringO 20 is housed on the piston 1.

The radially

exhaust stomatodeum

12 and 21 and 13 and 22 of the

double end seat

6 and 9 of left and right cylinder cap all has the double clean-up port 23 of processing, and passes through plug 24 sealings.

Air-filtering body 27 is equipped with at one-way sucting

valve

7 and 10 air-

breathing stomatodeum

25 and 26 external port place.

Working principle:

When piston 1 during to left movement, one-way sucting valve 7 is closed, one-way exhaust valve 8 is opened, gas is compressed in the cylinder chamber, piston 1 left side 4, externally inflate by exhaust stomatodeum 12 and gas tube 5, meanwhile, one-way sucting valve 10 is opened, one-way exhaust valve 11 is closed, and cylinder chamber 4, piston 1 right side is inwardly air-breathing by air-breathing stomatodeum 26 and exhaust stomatodeum 22; When piston 1 moves right, situation is just in time opposite, one-way sucting valve 10 is closed, and one-way exhaust valve 11 is opened, and gas is compressed in the cylinder chamber, piston 1 right side 4, externally inflate by exhaust stomatodeum 13 and air pipe 14 and exhaust stomatodeum 12 and gas tube 5, meanwhile, one-way sucting valve 7 is opened, and one-way exhaust valve 8 is closed, cylinder chamber 4, piston 1 left side is inwardly air-breathing by air-breathing stomatodeum 25 and exhaust stomatodeum 21, so moves in circles.
