Description
Technical field
This utility model relates to a kind of inflator for inflating to aerated product, particularly relates to a kind of bitubular hand-pulled inflator.
Background technology
Current hand-pulled inflator (is also inflator pump), and kind is quite a lot of, and wherein namely traditional type structure is used for, such as common people, inflator that aerated product is inflated.This kind of inflator has the stack shell of a tubular, stack shell is assembled with a piston operated by connecting rod, piston week side be provided with to recessed rubber cup, and be provided with mean for the handle that user grips in connecting rod top, extend a gas tube in stack shell lower end, separately the appropriate location of stack shell is provided with piston.When user's pull-up handle, air can enter below the piston inside stack shell, and when the air in stack shell will when pressing under handle, then can be pushed in gas tube by piston by user, it is provided that effect of a inflation.
For improving charging efficiency, market also occurs a kind of hand-pulled inflator having and being respectively provided with a piston in two stack shells and each stack shell, Chinese utility model patent " a kind of bitubular pump bowl " if a patent No. is ZL200520062135.7 (notification number is CN2809262U) discloses such a bitubular pump bowl, include a left side, right sleeve, left, right sleeve is enclosed within same cylinder mouth, on a left side, it is provided with a left side in right sleeve, right piston, left, right piston is respectively through a left side, right pull bar is connected with handle, cylinder mouth has aspirating hole, at cylinder mouth with left, a groove is had above the aspirating hole of one end that right sleeve socket-connects, the gas barrier plate of one and this groove match is set in groove.
Piston pump structure in two stack shells of existing bitubular hand-pulled inflator works simultaneously, can double raising charging efficiency, but it is not that charging efficiency is more high more good when inflation, general to relatively large aerated product inflation, in the incipient stage, charging efficiency is more high more good, at this moment bitubular hand-pulled inflator plays great role, but the carrying out along with inflation, aerated product internal gas pressure is more and more higher, because the effective piston area of bitubular hand-pulled inflator is monotubular hand-pulled inflator twice, therefore more to below, bitubular hand-pulled inflator receives resistance also for monotubular hand-pulled inflator twice, operation of inflating quite is required great effort.
In sum, existing bitubular hand-pulled inflator can be further improved.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of reasonable in design and can the bitubular hand-pulled inflator that switches over of bitubular modes of inflation and monotubular modes of inflation for above-mentioned prior art present situation.
The technical scheme that the above-mentioned technical problem of this utility model solution adopts is: a kind of bitubular hand-pulled inflator, including the first stack shell, the second stack shell, upper cover, handle and base, described upper cover covers the top being located at the first stack shell and the second stack shell simultaneously, described base covers the bottom being located at the first stack shell and the second stack shell simultaneously, it is provided with first piston in first stack shell, first piston is connected with handle by the first linkage tube, being provided with the second piston in second stack shell, the second piston is connected with handle by the second linkage tube；It is characterized in that: described first piston is provided with the first valve block only allowing gas to enter in the first linkage tube from the lower chamber of the first stack shell, described second piston is provided with the second valve block only allowing gas to enter in the second linkage tube from the lower chamber of the second stack shell；It is provided with in described handle and internal the first outlet chamber connected of the first linkage tube and second outlet chamber that connect internal with the second linkage tube, handle has and connects the extraneous outlet passageway with the first outlet chamber and connect the extraneous exhaust passage with the second outlet chamber, by the 3rd valve port connection between first outlet chamber and the second outlet chamber, 3rd valve port is provided with and only allows other the 3rd valve block entering in the first outlet chamber from the second outlet chamber, removable lining on described exhaust passage is connected to plug.
Improving further, the cross-sectional area of above-mentioned first stack shell is less than the cross-sectional area of the second stack shell.Because of under plug opening, only the piston in the first stack shell inflates arrangement works, and the cross-sectional area of the first stack shell is less than the cross-sectional area of the second stack shell, under the premise that pressure is certain, volume is more little, and to be subject to resistance more little, therefore only have the piston in the first stack shell to inflate in arrangement works situation, it is adapted at using when aerated product inner inflatable reaches certain pressure, and uses more laborsaving.
As preferably, above-mentioned first stack shell and the second stack shell are one-body molded together.It is easy to processing assemble, and profile is also more attractive, will not form gap between two stack shells.
Above-mentioned plug passes through the mode detachable connection of buckle on exhaust passage.The mode of buckle is easy to plug and is shirked.
The middle part of above-mentioned first piston is provided with the first screwed hole in order to threaded with the first linkage tube, and the bottom of the first screwed hole is provided with the first valve port that the lower chamber with the first stack shell communicates, and described first valve block is arranged on the first valve port.
The middle part of above-mentioned second piston is provided with the second screwed hole in order to threaded with the second linkage tube, and the bottom of the second screwed hole is provided with the second valve port that the lower chamber with the second stack shell communicates, and described second valve block is arranged on the second valve port.
For detecting the air pressure in aerated product in real time, above-mentioned handle is provided with the containing cavity communicated with outlet passageway, is provided with to detect the Pressure gauge of pressure in this containing cavity, and manometric pressure sensitive end is revealed in described outlet passageway.
Compared with prior art, the utility model has the advantage of: when plug blocks, piston in two stack shells gives the aerated product inflation being connected with outlet passageway simultaneously, under plug opening, the gas that second stack shell is squeezed into via the second linkage tube is discharged all through exhaust passage, under the effect of the 3rd valve block, the second linkage tube the gas squeezed into will not pass through the 3rd valve port, but is filled with in coupled aerated product either directly through outlet passageway.Namely only whether need to be opened by plug, just can switch in bitubular modes of inflation and monotubular modes of inflation.
