Embodiment
Illustrate specific embodiment of the present utility model with reference to the accompanying drawings.
Reference picture 1, Fig. 2, Fig. 3 and Fig. 4.A kind of fresh-keeping device for improving service life, including base 1, with 1 turn of the base
The upper lid 2 of dynamic connection and the vacuum extractor 3 being installed in the base 1.Wherein, the upper downside activity of lid 2 is embedded with least one
The elastic elastic device 9 for acting on lid 2 is installed in individual sheet metal 4, upside, and the elastic device 9 also passes with a sheet metal about 4
Dynamic connection；The upside of base 1 is equiped with the electromagnet 5 corresponding with the position of sheet metal 4.By setting sheet metal 4 to be inhaled with electromagnetism
Iron 5, user need to will only turn over a segment distance under upper lid 2, sheet metal 4 just can adhesive on electromagnet 5, it is simple to operate.
Reference picture 1, Fig. 2, Fig. 3 and Fig. 4.Specifically, elastic device 9 include one operation briquetting 91, a connecting rod 92 and
One spring 93, wherein, the upper end of connecting rod 92 is connected with operating briquetting 91, lower end is connected through upper lid 2 and with sheet metal 4；Bullet
Spring 93 is set in the outside of connecting rod 92, and operates briquetting 91 and abutted by spring 93 with the top surface of upper lid 2.Prior art is to close
The thickness deviation for sealing cotton requires that management and control is very tight（±0.3mm）, therefore it is very high to seal cotton scrappage.By set operation briquetting 91 with
Spring 93 so that spring 93 has a pretightning force all the time to upper lid 2, and seal of tube cotton height dimension is not bigger than normal or less than normal, spring
Pretightning force can ensure the sealing cotton contact sealing on upper lid 2 and base 1, be amplified to the use tolerance of sealing cotton（±1mm）,
Both sealing effectiveness is improved, also extends the service life of sealing cotton.
Reference picture 1, Fig. 2, Fig. 3 and Fig. 4.The upside of base 1 is also equiped with one stroke switch 6, the travel switch 6 and electromagnetism
Inhale the connection of the circuit of iron 5.In the present embodiment, the trip switch 6 is microswitch.By setting travel switch 6 so that electromagnet
5 without in running order all the time, only triggers travel switch, electromagnet 5 when rolling up lid under user to certain distance
Just start working, energy consumption is greatly reduced while operating efficiency is kept.
Microswitch is that have small contact separation and snap-action mechanism, and it is dynamic to carry out switch with defined stroke and defined power
The contact mechanism of work, is covered with shell, there is a kind of switch of drive rod outside it, because the contact spacing of its switch is smaller,
Therefore named microswitch, is called sensitive switch.Its operation principle is that outer mechanical force passes through actuated element（Push-piece, button, lever, rolling
Wheel etc.）Power is acted on action reed, snap action is produced when acting reed and being displaced to critical point, makes action reed end
Movable contact and fixed contact quick-make or disconnection.After the active force on actuated element is removed, action reed produces reversely dynamic
Make power, after actuated element reverse stroke reaches the action critical point of reed, instantaneously complete counteragent.
Reference picture 1, Fig. 2, Fig. 3 and Fig. 4.Specifically, the number of above-mentioned sheet metal 4 is two, and it is symmetrically positioned in lid 2
The left and right sides；The number of electromagnet 5 is also two, and corresponding with the position of a sheet metal 4 respectively；Elastic device 9
Number is also two, and corresponding with the position of a sheet metal 4 respectively.By being symmetrical set, the lid of lid 2 can be improved and set
Sealing when on base 1.
Reference picture 1, Fig. 2, Fig. 3 and Fig. 4.In the utility model, the upper downside of lid 2, which is embedded with one, seals cotton 71, on base 1
Side is embedded with a lower sealing cotton 72 with the upper sealing position correspondence of cotton 71.In addition, a heating wire 8 is also equiped with the upside of base, and
And the heating wire 8 is positioned at the lower inner side of sealing cotton 72.
Reference picture 1, Fig. 2, Fig. 3 and Fig. 4.By setting sheet metal 4 and electromagnet 5, conventional machinery engaging instead of
Formula, user need to will only turn over a segment distance under upper lid 2, upper lid 2 just can restart travel switch 6 certainly by it（Or gently pressed again with hand
Once upper lid starts travel switch）So that electromagnet 5, which is powered, produces magnetic attraction, and sheet metal 4 is with regard to energy adhesive to electromagnet 5
On, so that the sealing cotton of the downside of upper lid 2 and the sealing cotton of the upside of base 1 compress and sealed, make repeatedly in the absence of conventional fastener
With it is easy to wear the defects of；In addition, electromagnet absorption affinity >=6.0kg.f, upper sealing cotton contacts the pressure that sealing needs with lower sealing cotton
Power is >=2.0kg.f, therefore electromagnet 5 is fully able to meet the requirement sealed.
Reference picture 1, Fig. 2, Fig. 3 and Fig. 4.In the utility model, base 1 is included in the upper shell 11 that levels are set with
Housing 12, above-mentioned vacuum extractor 3 are installed between upper shell 11 and lower house 12.Vacuum extractor 3 includes being used to vacuumize
Vavuum pump 31 and electronics relief valve 32 for pressure release.By setting electronics relief valve 32 so that the utility model seals
After finishing, the energy releasing pressure automatically of electronics relief valve 32 flicks lid, opens and covers without manual operation, simplifies operation, lifting
Use comfort.Because vavuum pump 31 and electronics relief valve 32 are conventional technology, its specifically used method is herein not
Repeat again.
Reference picture 1, Fig. 2, Fig. 3 and Fig. 4.Comprised the following steps using the utility model：
1. a segment distance will be turned under upper lid 2, upper lid 2 just can restart travel switch 6 certainly by it（Or gently pressed again with hand
Once upper lid starts travel switch）So that electromagnet 5, which is powered, produces magnetic attraction；
2. electromagnetic attraction caused by electromagnet 5 sucks the sheet metal 4 on upper lid 2 together；Meanwhile with the metal
The operation briquetting 91 that piece 4 is connected by connecting rod 92 acts with sheet metal 4, so as to apply one to upper lid 2 by spring 93
Pretightning force, the upper sealing cotton 71 of the downside of lid 2 and the lower sealing cotton 72 of the upside of base 1 is set to compress and seal；
3. after sealing, user can start to operate the function button such as vacuum/sealing, and after the completion of machine operation, pcb board is automatic
Control electromagnet 5 powers off, and magnetic attraction disappears, while the built-in energization pressure release of electronics relief valve 32, and upper lid 2 is in upper sealing cotton 71
With being automatically springed open under the bounce of lower sealing cotton 72.
Specific embodiment of the present utility model is above are only, but design concept of the present utility model is not limited thereto,
All changes for carrying out unsubstantiality to the utility model using this design, all should belong to the row for invading scope of protection of the utility model
For.
