Description
Technical field
The present invention relates to a kind of manual inflatabling tool, particularly relate to a kind of three-phase hand-pulled inflator.
Background technique
Current hand-pulled inflator (being also air pump) kind is roughly divided into two kinds, and one is unidirectional hand-pulled inflator, and this hand-pulled inflator moves up and down in a round trip at piston, and be merely able to have single stroke to provide aeration, its charging efficiency is low.Another is the hand-pulled inflator of bidirectional inflating, and it can push away at handle, draw in two-way travel and all carry out inflation action, and this inflator has the high advantage of charging efficiency.As the Chinese utility model patent " two-way inflating pump " that the patent No. is ZL00255072.5 (notification number is CN2450405Y); The patent No. is the Chinese utility model patent " a kind of two-way inflating pump " of ZL200620100394.9 (notification number is CN2874057Y); They all disclose a kind of hand-pulled inflator of energy bidirectional inflating.
Current hand-pulled inflator, no matter be unidirectional (only inflating when pressing down) or two-way (pull-up presses down and all can inflate), all can not exceed certain throughput (liter/number of times), because receive the restriction of stack shell diameter and height.
The restriction of diameter is determined by the pressure needed.In general (according to standard DINEN16051-2), the rated pressure of hand-pulled inflator measures when the power of 60KG presses down.If so will make the air pump that easily can reach 1bar, the maximum airflow of piston needs to be 60KG/1bar=60cm2, and so maximum diameter will reach 87.4mm.
The restriction of height is determined by user's level of comfort.The stroke of hand-pulled inflator is more than 450mm, and using will be uncomfortable, and unavailable.Therefore a unidirectional hand-pulled inflator, if need easily to reach 1bar, the throughput each time needed in theory is 60cm2x45cm=2.7L, is exactly 2.7+2.7=5.4L if two-way.
No matter the hand-pulled inflator of what we said above is all single piston is two-way or unidirectional.Commercially there is the hand-pulled inflator of a new double-piston, unidirectional, if the patent No. is the Chinese utility model patent " double-piston three pipe high-pressure pump " of ZL90226082.0 (notification number is CN2080999U).Two pistons work simultaneously, until reach 50% of about pressure maximum, then by a venting plug, the pumping action of a piston are canceled, like this just can reach pressure maximum.The throughput of air pump to be turned over doubly by this scheme, but only one-way only operation.In theory, the throughput of the air pump of this double-piston equals the air pump of a single piston two-way, but more expensive and heavy.In fact, if we illustrate with 1bar always, the throughput of this air pump is 2.7Lx2=5.4L, is equal to the air pump of a single piston two-way, but bulking value and price are all double.
