The purpose of this utility model just provides a kind of easy vacuum extractor that has, and can reach the sealing of container easily and vacuumizes, and can conveniently remove the composite set of the negative pressure of vacuum vessel again.

The utility model is realized by following scheme:

Whole composite set partly is made up of container with lid and suction-pump two, is equipped with one on container cover top and made by elastomeric material, the check valve that can interlock with the pump bottom.When twitching the inner carrier tube that pump is communicated with atmosphere, the sealing blow off valve bottom it is airtight between the pump inner/outer tube, thereby forces the interior gas of container to enter the pump urceolus by check valve.When inner carrier was pushed back, air outlet valve unclamped the gas that is extracted into urceolus is communicated with atmosphere (being the inner carrier tube).Because the outer air pressure of container is greater than the pressure in the container, thereby make the material deformation of check valve opening part and, and the gas in the urceolus is discharged through air outlet valve, exhaust small sircle hole with the sealing of opening mouth.Several times can exhaust the gas in the container so repeatedly, make in the container near or reach vacuum state.Pump can be taken down from container other placement then or be arranged in the gusset of container.

Remove the vacuum state in the container, need only pinch check valve opening mouth with hand, make in the container to be interlinked to the outside, atmosphere enters container and promptly removes negative pressure in the container, can open container cover.Thereby reach the purpose of this utility model.

Accompanying drawing is container of the present utility model and suction-pump coupled condition full section scheme drawing.

Wherein: the 1-cylinder body; The 2-lid; The 3-seal ring; The 4-check valve; The 5-urceolus; The 6-inner core; 7-seals blow off valve.

Shown in the figure, container is by cylinder body 1, and container cover 2 forms, in the inner groovy 21 places embedding of container cover 2 Be placed with sealing ring 3, insert a check valve 4 in the recessed groove above lid 2 (or protruding tube) 22, at groove 22 bottom is provided with one to several perforates 23. The cooperation of one-way valve seat 41 and corresponding groove 22 Adopt interference fit. Middle part, check valve 4 top is provided with a slot-shaped opening mouth 42, and they are four years old The Zhou Youyi circle is higher than the direct projection 43 that contacts with mouth 42 of restriction pump of opening mouth 42, at check valve There is a flange collar 44 4 outer borders. Suction-pump is by urceolus 5, inner carrier tube 6 and umbrella sealing exhaust Valve 7 forms; Being provided with one at the lower bottom part of urceolus 5 inner chambers can correspondingly with flange collar 44 interlock and seal Groove 51; Inner carrier tube 6 directly is communicated with atmosphere, is provided with valve opening 61 in the middle of the bottom, and its bore slightly Greater than the neck 71 of umbrella sealing air bleeding valve 7, sealing air bleeding valve 7 has up and down two

umbrella crowns

72 and 73, can Play sealing air bleeding valve 7 is floated and limit the effect of its position, be provided with symmetry at lower umbrella crown 73 Arc lack 74, gas lacks 74 and back down through space, neck 71 outside by the inner chamber of urceolus 5 through arc during exhaust Upper umbrella crown 72, the inner chamber and the atmosphere that flow to inner carrier tube 6 connect.

Below in conjunction with accompanying drawing embodiment of the present utility model is described further:

With the tongue 44 of 5 end of the urceolus groove 51 of suction-pump and check valve 4 be interlockingly connected, pressure seal.Thereby make the inner chamber of the urceolus 5 of pump, by the opening mouth 42 of check valve 4, with container intracavity on-off mutually.When extracting pump inner carrier tube 6, the outer ring of the last umbrella crown 72 of umbrella sealing blow off valve 7 is adjacent to the connection at the inner chamber of inner carrier tube 6, cut off gas the flowing in urceolus 5 in the piston barrel 6, thereby make the space in the urceolus 5 form negative pressure, the opening mouth 42 of the gas that forces container intracavity by check valve 4 to urceolus 5 inner chambers flow, behind urceolus 5 aerificatioies, during with piston barrel 6 pushing downwards, the pressure of urceolus 5 inner chambers strengthens, and the pressure in the container is less relatively, the pressure compression check valve 4 that container is outer, produce material deformation, opening mouth 42 is closed.Because volume reducing, gaseous tension increases, and the following umbrella crown 73 that gas will seal blow off valve 7 is pushed the lower bottom part of piston barrel 6 to, along the arc scarce 74 of umbrella crown 73 and the slit of valve opening 61 down, backs down the epicoele that umbrella crown 72 enters the inner carrier tube, puts and returns atmosphere.Under the pressure of atmosphere, seal ring 3 elastic deformations, turgor plays sealing function in the groove 21 of lid 2 and step 11 places of cylinder body 1.Returning multiple carrying several times pushes away and gas in the container can be found time substantially until vacuum.
