Abstract
The utility model relates to a vacuum exhauster, specially relates to a hand-operated vacuum air exhausting barrel which is used to pump vacuum for a vacuum fresh-keeping box, which comprises a barrel body, a piston rod in the barrel body, a piston which is arranged on the front end of the piston rod and a handle which is arranged on the back end of the piston rod, wherein a sealing pad is arranged on the front end of the barrel, the sealing pad comprises an inner portion which is clung to the inner walls of the barrel, an outer portion which is clung to the outer walls of the barrel and a transition portion which is connected with the inner portion and the outer portion, and a pyramidal face structure is arranged on the outer wall of the front end of the outer portion of the sealing pad. The device has simple structure, is conveniently formed into encapsulation with a one-way valve, can fast vacuumize a container, and solves the problems existing in the prior art of complicated structure of the hand-operated air exhausting barrel, smaller air exhausting nozzle opening, slower air exhausting speed, and unfavorable sealing effect between the air exhausting nozzle and the one-way valve and the like.
Description
Technical field
The utility model relates to a kind of vacuum suction device, particularly a kind ofly is used for the manual vacuum pump bowl that vacuum crisper vacuumizes.
Technical background
At present people for the preservation majority of food fresh keeping and protection against the tide, mildew-resistant article be with some easily containers of sealing after the motor-drive pump device vacuumizes, seal again.Its pump-unit complex structure, cost height, often to consume more electric energy, when going out behind the sealed utensil of unpacking, also be not easy to utensil is repeated to vacuumize sealing once more again because of pump-unit heaviness or non-transformer, the pump-unit that has is bled, and the degree of vacuum of back container is low, sealing back is fresh-keeping, moisture effect is not good, particularly difficult Chu spread to general in, be extensive use of among the low-income household and under multiple occasion.
So there is the people to propose a kind of manual pump bowl (patent No.: Chinese patent application 97219207.7) by name, it includes cylinder barrel, is loaded on the piston that cylinder barrel interior tubular shape piston rod, piston rod two ends are fixed with handle respectively and working surface flare piston ring is housed outward, the end that piston is housed in the cylinder barrel has the bottom of being with the mouth of bleeding, the mouth of bleeding is bevel-type and the tubular air extraction connector that is radial arrangement, the cone rubber exhaust plug with the crimping of elasticity pressurizing block in the piston cavity.Above-mentioned its structure of manual pump bowl is comparatively complicated, and the mouth opening of bleeding is less, and pumping speed is slower, and simultaneously, the sealing effect of bleeding between mouth and the one-way valve is relatively poor.
Summary of the invention
It is a kind of simple in structure that the utility model purpose is to provide, be convenient to and one-way valve between form sealing, can be fast with the evacuated manual vacuum pump bowl of container, its structure of manual pump bowl that has solved the prior art existence is comparatively complicated, and the mouth opening of bleeding is less, pumping speed is slower, simultaneously, and problem such as the sealing effect between mouth and the one-way valve of bleeding is relatively poor.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: it comprises cylindrical shell, piston rod in the cylindrical shell, be located at the piston of piston rod front end, be located at the handle of piston rod rear end, described barrel front end is provided with sealing gasket, described sealing gasket comprises inside that is close to cylinder inboard wall and the outside that is close to simplified outer wall and is connected inside and outside transition part that described sealing gasket outer front end outer wall is provided with cone structure.The utility model directly with barrel front end as the mouth of bleeding, its aperture is bigger, the resistance that piston is subjected to when bleeding is less, simultaneously, sealing gasket being set as the barrel front end of mouth of bleeding and forming cone structure, can be convenient to form sealing between the utility model and the one-way valve, thereby be evacuated to taking out container fast at the outside outer wall of sealing gasket, to quicken pumping speed, easy to use.
As preferably, be provided with annular convex and the annular groove that cooperatively interacts between described sealing gasket outer internal wall and the cylinder body outer wall, thereby can guarantee to combine more reliably between sealing gasket and the cylindrical shell, prevent coming off of sealing gasket.
As preferably, described piston rod and piston link position are provided with annular caulking groove, are provided with the seal ring that cooperates with it in the described caulking groove.
As preferably, described handle is provided with turning up of cooperating with the cylinder back-end outer wall and extends axially portion, and described turning up extends axially the portion end and be provided with the annular convex that turns up, and described cylinder body outer wall is provided with the annular stop convex body that cooperates with the annular convex that turns up.Annular stop convex body by cylinder body outer wall and the handle annular convex that turns up that extends axially the portion end that turns up cooperates, but the formation of limited piston bar separates sealing gasket to prevent piston with cylindrical shell.
As preferably, described handle outer wall is provided with two finger recesses that are oppositely arranged.Wherein, two finger recesses that are oppositely arranged can be convenient to the grasping to handle, thereby conveniently bleed operation.
Therefore, the utlity model has simple in structure, be convenient to and one-way valve between form sealing, can be fast with characteristics such as container are evacuated.
