Abstract

A continuous dual purpose air cylinder includes the air cylinder body, a cylinder cover, a piston, a piston rod, a handle, a bidirectional air tube, multifunctional base seat, check valves and an air hatch joint plate. The present invention generates air flow during the moving process of the cylinder piston, guides the air flow by the bidirectional air tube, makes multiple check valves in the inner part of the multifunctional base seat continually change open and close status to realize continuous air pump and air suction. The dual purpose air cylinder is simple in structure, convenient in manufacture and strong in practicability.

Description

Continuous type dual-purpose inflator

Technical field:

The present invention relates to a kind of two-way inflator, particularly a kind of have an instrument of air-breathing function of inflating continuously, belongs to everyday tools.

Background technique:

Existing inflator adopts single acting piston, therefore has only simple function, or air-breathing or inflate.Patent publication No. CN1746498A is illustrated to have and inflates air-breathing bifunctional inflator, also adopt single acting piston, promptly inflate or air-breathing can only when promoting piston, working to a direction motion, inflate during backward stroke of the piston or the air-breathing work state that seizes up, working efficiency has only half, and structure is comparatively complicated, also shows slightly trouble when operation, and the position of air cylinder is beaten, need be rotated when inhaling state in conversion.

Summary of the invention:

Problem to be solved by this invention is: no matter whichaway moves, inflator is in all the time inflates and air-breathing continuous duty piston, can effectively increase work efficiency in inflator.And the gas in the container directly can be charged into another container.

For realizing above purpose, the present invention changes traditional pump leather cup into two-way airtight piston, air cylinder cover has added the piston pole socket that has seal action, and increase a two-way air pipe and kinetic energy base more than, the inner passage that four one-way valves is arranged in the multifunctional base and be attached thereto, the air-flow that motion produces to piston two-way carries out orientation control respectively, thereby realizes the continuous operation of inflator.

Description of drawings:

Fig. 1 is a continuous type dual-purpose inflator overall structure schematic representation

Fig. 2 is a multifunctional base internal structure generalized section

Accompanying drawing 1 explanation: this continuous type dual-purpose inflator, one piston (2) is arranged in inflator stack shell (1), the piston edge is fluted and " O " RunddichtringO (3) is arranged, piston rod (4) passes the piston pole socket (6) in the middle of the air cylinder cover (5), the piston pole socket is fluted and " O " RunddichtringO (7) is arranged, and the piston rod two ends are connected with the handle (8) of piston respectively.Inflator has the two-way air pipe (9) of being close to stack shell outward, its two ends connect the last gas port (10) of stack shell and the following gas port (12) of the tube end (11) respectively, tube has at the end one to protrude the outer rectangle (13) of circle, and it mainly acts on is fixing air pipe lower end, and an end and stack shell fix as one.Tube has an air outlet hole (14) and an inlet hole (15) at the end, and there is a following gas port at the rectangle place.

Stack shell and multifunctional base (16) are connected and fixed with screw (17), and there is sealing gasket (18) centre, and the edge of 3 airflow holes (19) of sealing gasket all exceeds sealing gasket integral body, and effect is to make each hole be in independently sealing state.There are gas-entered passageway (20), outlet passageway (21) and air guide channel (22) to communicate with air outlet hole, inlet hole and following gas port at the bottom of the tube respectively on the multifunctional base.

There is " O " RunddichtringO (23) air cylinder cover and stack shell screw-on place, and there is tightening nut (24) piston and piston rod joint, are with damping spring (25) on the inside and outside piston rod of inflator respectively.

Accompanying drawing 2 explanations: the main effect of multifunctional base is that the control air-flow is made directional flow.

Working procedure when it is air-breathing is:

When piston moves upward, air-flow flows to one-way valve 1. (29) from the sucking pipe interface (27) of gas port fishplate bar (26) through inner conduit (28), 1. valve is opened, air-flow enters inflator A chamber through gas-entered passageway and inlet hole, piston pulls on an A chamber of taking offence and increases gradually, inflator B chamber is compressed gradually, the gas of B chamber flows to one-way valve 2. (30) through last gas port, two-way air pipe, following gas port, outlet passageway, inner conduit, 2. valve is opened, and (31), steam outlet pipe interface (32) flow out air-flow from the air outlet.In this process one-way valve 3. (33) and one-way valve 4. (33) be in closed condition.

One-way valve 1., 3. fastening with screw (35) silently and seal washer (36) with the place of communicating, the external world, separate with the external world.

The gas port fishplate bar has with rectangle groove (37), and effect is that giving vent to anger of two strokes of piston converged into a hole output.

When piston moves downward, 3. air-flow flows to one-way valve from the sucking pipe interface through inner conduit, 3. valve is opened, air-flow enters the B chamber through air guide channel, following gas port, two-way air pipe and last gas port, piston continues pulling B chamber and increases gradually, and the gas of A chamber is compressed through air outlet hole and flows to one-way valve 4., and 4. valve is opened, and air-flow flows out through air outlet, outlet passageway steam outlet pipe interface.1. and 2. one-way valve is in closed condition in this process.

Working procedure when inflating and principle are the same when air-breathing, and different is: being leather hose to be connected on the interface of giving vent to anger connect the inflation object when inflating, is leather hose to be connected on air-breathing interface connect air-breathing object when air-breathing.
