One inflating rod (50), it has a bore greater than inner barrel (40) and less than the middle pipe (51) of outer cylinder body (30), middle pipe (51) is arranged in the outer cylinder body (30), be sheathed on inner barrel (40) outside, in pipe (51) top closure and establish a lever (52), in pipe (51) bottom be provided with and inflate piston (53), the piston (53) of inflating is central to provide wherein for inner barrel (40), and establish second air intake valve (532) of air inlet up only, outside butt outer cylinder body (30) inwall, and establish first air intake valve (531) of only air inlet down, fixed piston (41) outer rim on pipe (51) inner edge and inner barrel (40) top connects in addition, and establishes the 3rd air intake valve (411) of only air inlet up; And
One air pipe (60) is a soft body, the affixed base of one end (10) air outlet (11), in addition termination is established an air outlet adapter (not shown), the above-mentioned member of nationality constitute a pump.
Be provided with one in the aforementioned base (10) and be positioned at first vertical passage (12) that central authorities are communicated with inner barrel (40), and be positioned at second vertical passage (13) that side is communicated with outer cylinder body (30), and establish first crosspassage (14) from first vertical passage (12) bottom and be connected air outlet (11), establish second crosspassage (15) from second vertical passage (13) bottom with respect to second crosspassage (15) below and be connected air outlet (11), be provided with in addition first one-way valve (16) of (11) direction air inlet only in first vertical passage (12) towards the air outlet, in second crosspassage (15), establish the first unidirectional valve member (17), only can be in order to control gaseous from second vertical passage (13) (11) direction air inlet towards the air outlet.
Aforementioned again base (10) is established a perforation (18) in second vertical passage (13) bottom, and adjusting part (20) has an activity set and is located at the valve member (21) that second vertical passage (13) bottom perforation (18) is located, valve member (21) bottom cooperates a spring (23) and is arranged at depression bar (22) on the base (10), whether opens in order to control second vertical passage (13) bottom perforation (18).
Aforementioned air pipe (60) can rotate air pipe (60) by the air outlet (11) of a rotary connecting joint (61) winding base (10).
When this creation pump uses, can connect the object that desire is inflated by the terminal air outlet adapter of air pipe (60), hold again on the lever (52) on inflating rod (50) top and draw, as shown in Figure 2, make outer cylinder body (30) bottom inflate pipe (51) in the space A of piston (53) below and the inflating rod (50) relatively and form negative pressure with respect to the space B of fixed piston (41) top, make the gap of air between outer cylinder body (30) and inflating rod (50) enter to space A, enter in the space B by the 3rd air intake valve (411) with respect to the space C air of inflating between piston (53) and fixed piston (41) in the middle pipe (51) by first air intake valve (531).
Secondly, press down inflating rod (50), as shown in Figure 3, make and inflate the air of piston (53) pressurization space A, make it push the first unidirectional plate (17) open and flow to air outlet (11) via second vertical passage (13) commentaries on classics second crosspassage (15), manage the air of the closed end pressurization space B on (51) top in addition in the nationality inflating rod (50), make it push interior second one-way valve (42) of inner barrel (40) top fixed piston (41) open, first one-way valve (16) commentaries on classics first crosspassage of pushing open again in base (10) first vertical passages (12) through inner barrel (40) (14) flows to air outlet (11), and the forced air that is collected to air outlet (11) promptly carries out the fast aeration effect of big gas output via air pipe (60), and so repeatable operation is that sustainable object to the desire inflation carries out aeration.
When using pump, the user continues object is carried out aeration after a period of time, inner is high pressure conditions, at this moment, if when needing again this object to be continued to carry out aeration, for allowing the laborsaving operation of user, as shown in Figure 4, can press down the depression bar (22) of adjusting part (20), raise ejection valve member (21), make the ejection valve member (21) and the perforation (18) of base (10) second vertical passage (13) bottoms be opening state, at this moment, the air pressure of locating because of base (10) air outlet (11) is higher than the air pressure at place, second vertical passage (13) bottom, so make the first unidirectional valve member (17) close connected state between second vertical passage (13) and second crosspassage (15).
Secondly, press down inflating rod (50), at this moment, interior piston (53) air pressurized of being inflated of space A, a part of air flows to space C and fills up by inflating second air intake valve (532) in the piston (53), portion of air crack and perforation (18) discharging decompressing certainly between between second vertical passage (13) and ejection valve member (21), allow the user can press down inflating rod (50) more effortlessly, on the other hand, inflating rod (50) is when pressing down, the space that is arranged in the space B place is by the pressurization of inflating rod (50) pipe (51) top seal end, make pressurized air push interior second one-way valve (42) of inner barrel (40) top fixed piston (41) open, first one-way valve (16) commentaries on classics first crosspassage of pushing open again in base (10) first vertical passages (12) through inner barrel (40) (14) flows to air outlet (11), wherein and utilize sectional area little, go out the big principle of atmospheric pressure, can charge in the object than the air of labour-saving mode of operation output higher pressure.
The aforementioned depression bar (22) that presses down adjusting part (20), ejection valve member (21) makes the bottom perforation (18) of second vertical passage (13) be opening state, and the first unidirectional valve member (17) is when closing the connected state of second crosspassage (15) and second vertical passage (13), in the process that high pressure is inflated, the air pressure of locating because of air outlet (11) is kept the air pressure greater than space A always, so when forcing the first unidirectional valve member (17) sealing second crosspassage (15), and end valve member (21) decline with its terminal supporting, and keep the opening state of second vertical passage (13) bottom perforation (18), second crosspassage (15) is a closed state, until inflate finish after, air outlet (11) is located air pressure and is reduced i.e. reinstatement.
In sum, the structural design of its innovation of the utility model nationality really can provide and commonly use the inflator structure that pump has more handy, rapid operation, practical effect ideal.
