Abstract
The utility model discloses an air extraction cylinder which comprises a cylinder body, a handle and a piston rod, wherein the handle is installed at the upper end of the piston rod, a connecting part is installed at the bottom end of the cylinder body, a hollow piston cushion block is arranged at the lower end of the piston rod, a ventilating mechanism which is communicated with an internal space of the piston cushion block is arranged on the side wall of the piston cushion block and comprises a ventilating hole and a sticking membrane, the ventilating hole is a through hole which is formed in the side wall of the piston cushion block and is communicated with the internal space of the piston cushion block, and the sticking membrane is arranged on the outer wall of the piston cushion block and shields the ventilating hole. The air extraction cylinder is used for extracting air in articles such as vacuum receiving bags, is convenient to use, is high in efficiency and saves the time and the labor.
Description
Technical field
The utility model relates to a kind of pump bowl, specifically a kind of pump bowl that vacuumizes to small containers.
Background technology
Daily household receptacle like the vacuum collecting bag, need utilize pump bowl with the air extraction in the bag when taking in article, make to be vacuum state in the bag basically.The pump bowl of present homebrew is generally all for manually bleeding, and is convenient and swift.Pump bowl generally comprises cylindrical shell, handle and piston rod, deflates through moving up and down of piston rod.Yet, existing pump bowl, the effect of bleeding not is very good, needs more time and strength, is with to the people to be inconvenience.
The utility model content
The technical matters that the utility model will solve provides a kind of easy to use, the pump bowl that pumping efficiency is high.
In order to solve the problems of the technologies described above, the utility model is taked following technical scheme:
A kind of pump bowl; Comprise cylindrical shell, handle and piston rod, handle is loaded on the piston rod upper end, and attaching parts is equipped with in the cylindrical shell bottom; Said piston-rod lower end is provided with the piston cushion block of hollow, and this piston cushion block sidewall is provided with the ventilative mechanism that communicates with this piston cushion block inner space.
Said ventilative mechanism comprises breather hole and pad pasting, and breather hole is the through hole that is connected with this piston cushion block inner space that is located on the piston cushion block sidewall, and pad pasting is located on the piston cushion block outer wall and is blocking breather hole.
Said attaching parts is the block that is sleeved on the cylindrical shell bottom, and block is provided with coupling end, offers screw thread on this coupling end outside face.
The utility model is offered breather hole through improvements over the prior art on the piston cushion block of piston-rod lower end, help more bleeding, and has improved pumping efficiency.
Description of drawings
Accompanying drawing 1 is the utility model perspective view;
Accompanying drawing 2 is the utility model decomposing state structural representation;
Accompanying drawing 3 is the perspective view of piston cushion block in the utility model.
The specific embodiment
For the ease of those skilled in the art's understanding, the utility model is done further to describe below in conjunction with accompanying drawing.
Like accompanying drawing 1,2, shown in 3; A kind of pump bowl; Comprise cylindrical shell 1, handle 2 and piston rod 3, handle 2 is loaded on piston rod 3 upper ends, and attaching parts 4 is equipped with in cylindrical shell 1 bottom; Said piston rod 3 lower ends are provided with the piston cushion block 5 of hollow, and these piston cushion block 5 sidewalls are provided with the ventilative mechanism that communicates with these piston cushion block 5 inner spaces.Should ventilative mechanism comprise breather hole 6 and pad pasting 7; Breather hole 6 is for being located at the through hole that is connected with these piston cushion block 5 inner spaces on piston cushion block 5 sidewalls; Pad pasting 7 is located on piston cushion block 5 outer walls and is blocking breather hole 6, and pad pasting 7 parts stick on the piston cushion block outer wall and shelter from breather hole.For the ease of assembling, attaching parts is the block that is sleeved on the cylindrical shell bottom, and block is provided with coupling end 8, offers screw thread on this coupling end outside face.
The utility model is applied in the article such as vacuum collecting bag; Be connected with air suction valve on the vacuum collecting bag through attaching parts, then M/C, up carrying handle hand; Piston rod is up moved; Portion gas directly flows out from piston cushion block and the gap of tube between sidewall, a part of gas gets in the piston cushion block and pressurized wash open pad pasting from the breather hole discharge current to ambient atmosphere, the piston cushion block is close to cylinder inboard wall in the time of downward; And pad pasting is under pressure to influence and shelters from breather hole, and extraneous gas can not got into.
