Description
Technical field
The utility model relates to vacuum evacuation devices, and in particular to a kind of two way seal vacuum evacuation device.
Background technique
Chinese patent literature CN103712408A disclosed on April 9th, 2014 a kind of vacuum fresh-keeping system and its
Control method.Including seal box, moving system and control system, the seal box first equipped with control folding seal box is logical
It disconnecting and closing, the moving system includes motor and the vacuum pump that is electrically connected with motor, and vacuum pump is connected to seal box with connecting tube,
The control system is electrically connected the first on-off switch and motor, the seal box are also in series at least one auxiliary seal box, it
Between connected by the connecting tube with the first check valve, the setting direction of check valve is that auxiliary seal box is connected to seal box direction,
The second on-off switch whether detection auxiliary seal box is opened is equipped on auxiliary seal box.This vacuum fresh-keeping system structure is multiple
Miscellaneous, operation is also more troublesome, enables user less satisfied.
Utility model content
Simple, flexible operation that the purpose of this utility model is to provide a kind of structures, pumping easy to use, two way seal are true
Empty device, in place of overcome the deficiencies in the prior art.
It is described close by a kind of two way seal vacuum evacuation device that this purpose designs, including vacuum generator and sealing container
Two way seal valve is provided on envelope container.
Further, upper sealed body, lower sealed body and channel are provided on the two way seal valve.
Further, the two way seal valve is elastomer.
Further, the vacuum generator bottom is provided with the first connecting pin, and the is provided at the top of the sealing container
Two connecting pins, second connection end and the first connecting pin are detachably connected.
Further, elastic sealing element is provided between the vacuum generator bottom and the sealing container top edge.
Further, the elastic sealing element is annular.
Two way seal valve is provided in the utility model in sealing container, be provided on the two way seal valve upper sealed body,
Lower sealed body and channel, the two way seal valve are elastomer.Since valve body is the elastic two-way over-surplus fit structure of I-shaped,
So can realize two-way sealing function in its natural state, even if there being liquid in container, container is put upside down can be close
Envelope.
It is provided with elastic sealing element between vacuum generator bottom and the sealing container top edge in the utility model, when
When vacuum generator is connect with sealing container, the surrounding edge of elastic sealing element and sealing container forms sealing, so as to so that described
Reach between vacuum generator and the peripheral wall of sealing container and seal air tight and keep the location structure of the sealing container more firm,
Leakproofness is further increased, vacuumizes efficiency to further improve.
A kind of working principle of two way seal vacuum evacuation device of the utility model is as follows:
Vacuum: starting host (vacuum generator) starts to vacuumize, due to pressure difference and the work of elastic sealed body
With make host to sinking；Since host is to sinking so that host bottom presses to valve body, valve body is to sinking, and upper sealed body is to turning over
It rises, leaves sealing surface；Lower sealed body moves down, and leaves lower sealing surface；The included groove of valve body forms channel；So that holding
The inside and outside connection of device, can be realized in container after connection and vacuumizes.
It vacuumizes completion: vacuumizing completion, the solenoid valve in host is deflated, since the effect of elastic sealed body is so that host
It is raised above；Host no longer compression valve body, due to the effect of pressure difference, upper sealed body is bonded valve body with upper sealing surface, forms sealing
State.
Deflate: deflation only needs that deflation function can be realized by pressure valve top with hand.
In conclusion the utility model has the characteristics that structure is simple, flexible operation, easy to use, two way seal.
Detailed description of the invention
Fig. 1 is the non-evacuated state schematic diagram of two way seal vacuum evacuation device described in the utility model.
Fig. 2 is two way seal valve enlarged diagram in the utility model.
Fig. 3 is two way seal vacuum evacuation device evacuated state schematic diagram described in the utility model.
Fig. 4 is sealing container nature schematic diagram in the utility model.
In figure: 1 is vacuum generator, and 2 be sealing container, and 3 be two way seal valve, and 4 be elastic sealed body, and 5 connect for first
End is connect, 6 be second connection end, and 301 be upper sealed body, and 302 be lower sealed body, and 303 be channel.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments.
Referring to figures 1-4, a kind of two way seal vacuum evacuation device, including vacuum generator 1 and sealing container 2, it is described close
Two way seal valve 3 is provided on envelope container 2.
In the present embodiment, upper sealed body 301, lower sealed body 302 and channel 303 are provided on the two way seal valve 3.
The two way seal valve 3 is elastomer.
1 bottom of vacuum generator is provided with the first connecting pin 5, is provided with the second connection at the top of the sealing container 2
End 6, second connection end 6 and the first connecting pin 5 are detachably connected.
1 bottom of vacuum generator and the sealing container are provided with elastic sealing element 4 between 2 top edge.
The elastic sealing element 4 is annular.
Referring to Fig. 3, the working principle of the two way seal vacuum evacuation device is as follows:
Vacuum: starting host (vacuum generator) starts to vacuumize, due to pressure difference and the work of elastic sealed body
With make host to sinking；Since host is to sinking so that host bottom presses to valve body, valve body is to sinking, and upper sealed body is to turning over
It rises, leaves sealing surface；Lower sealed body moves down, and leaves lower sealing surface；The included groove of valve body forms channel；So that holding
The inside and outside connection of device, can be realized in container after connection and vacuumizes.
It vacuumizes completion: vacuumizing completion, the solenoid valve in host is deflated, since the effect of elastic sealed body is so that host
It is raised above；Host no longer compression valve body, due to the effect of pressure difference, upper sealed body is bonded valve body with upper sealing surface, forms sealing
State.
Deflate: deflation only needs that deflation function can be realized by pressure valve top with hand.
