Enter back into upper air valve gas passage 3531, after the second interface 352 through upper air valve 35 flow out to vacuum pumping pump 334.When
When needing vacuum breaker, draw-ring type key 5 can be flipped up by user, at this time the other side shaft position 51 of draw-ring type key 5
Upper air valve ontology 353 can be depressed, so that lower air valve ontology 41 be driven to move down, keeps the lower air valve on lower air valve ontology 41 close
Seal 42 removes lower air valve mounting hole 12, has gap, crisper between such lower air valve 4 and the hole wall of lower air valve mounting hole 12
Outer gas is able to enter in keeping box body 20.In addition, user can also directly use finger after vacuumizing box 3 and being disassembled
Lower air valve ontology 41 is pressed, 20 vacuum breaker of keeping box body is made.
As shown in Fig. 2, Fig. 6, Fig. 7 and Figure 12, vacuumizing box locked instrument 34 includes position blocking pin 341 and position blocking pin spring
342, position blocking pin 341, which is movably arranged on, to be vacuumized in the position blocking pin mounting groove 314 being arranged inside box lower cover 31, position blocking pin spring
342 are installed between the tail portion of position blocking pin 341 and the inner wall of position blocking pin mounting groove 314, and the head 3412 of position blocking pin 341 can be from
It vacuumizes the pin hole 315 that 31 side of box lower cover opens up and stretches out and be inserted into 11 inner wall of top mounting groove of fresh-keeping cover ontology 1 and open up
The first retaining groove 14 in, the top of position blocking pin 341 is equipped with slide block 3411, and the upper end of slide block 3411 is from vacuumizing on box
It is externally protruded in the poke hole 321 that lid 32 opens up, in addition, the lateral wall for vacuumizing box lower cover 31, which is equipped with to be located at, vacuumizes box
The detent convex body 316 of 34 opposite side of locked instrument offers on 11 inner wall of top mounting groove of fresh-keeping cover ontology 1 for vacuumizing
The second retaining groove 15 that the detent convex body 316 of box lower cover 31 is placed in, the second retaining groove 15 are located at the first retaining groove 14
Opposite side.When needing disassembly to vacuumize box 3, as long as user stirs the slide block 3411 on position blocking pin 341 and can make detent
The first retaining groove 14 is exited on the head 3412 of pin 341.
For the ease of user record and checking date saved, as shown in Fig. 1 and Figure 13, the top of fresh-keeping cover ontology 1 can be with
It is installed with the date mark ring 6 positioned at 11 outer ring of top mounting groove, label has the number of month and number of days on date mark ring 6,
The mobile pointer 7 of number of days and month mobile pointer 8 are movably installed on date mark ring 6.In use, user can refer to number of days movement
Needle 7 is moved at corresponding number of days position, and month movement pointer 8 is moved at corresponding month position.
In addition, as shown in Fig. 3 and Figure 14, it, can be fresh-keeping in order to intuitively indicate whether crisper is in vacuum state
Vacuum state instruction device is set on box.Specifically, fresh-keeping cover ontology 1 is equipped with indication key mounting groove 17, indication key mounting groove
17 bottom offers the through hole 18 through 1 bottom of fresh-keeping cover ontology, and the inside of indication key mounting groove 17 is installed with indication key
Seat 9 indicates to be movably installed with vacuum state indication key 16 and the sponge 19 positioned at the lower section of vacuum state indication key 16 in keyseat 9,
The bottom of vacuum state indication key 16 is equipped with the plug 161 for blocking through hole 18, and plug 161 can pass through sponge 19.?
During keeping box body 20 vacuumizes, under the action of negative pressure, vacuum state indication key 16 can move down and compress sea
Silk floss 19, until the plug 161 of vacuum state indication key 16 blocks the through hole 18 of fresh-keeping cover ontology 1.When crisper is in vacuum
When state, vacuum state indication key 16 bounces back downwards, and when crisper is in non-vacuum, vacuum state indication key 16 is in sea
It raises upward under continuous 19 elastic reactions.
Working principle of the present invention is as follows:
Fresh-keeping article will be needed to be placed in keeping box body 2, cover fresh-keeping cover ontology 1, box 3 then will be vacuumized and be pressed into
Into the top mounting groove 11 of fresh-keeping cover ontology 1, vacuumizing box 3 at this time can be clamped admittedly by position blocking pin 341 and fresh-keeping cover ontology 1
Fixed, at the same time, the touch part 3322 of power switch 332 can be in contact with fresh-keeping cover ontology 1, to open power supply power supply dress
It sets, vacuum pumping pump 334 is started to work, and the gas in keeping box body 2 is discharged outward.When the negative pressure value in keeping box body 2 reaches
When preset value, the gas in keeping box body 2 is exhausted, and vacuum pumping pump 334 stops working, and vacuum state indication key 16 is to next time
Contracting.Due to being in vacuum state in keeping box body 2, so fresh-keeping box cover 10 cannot be opened, to protect internal object
Product are stored always under vacuum conditions, are during which entered if any a small amount of air, and it is true that vacuum pressure switch 333 can be again started up pumping
Sky pump 334.
When that need to open fresh-keeping box cover 10, user can be with pull-up draw-ring type key 5, and draw-ring type key 5 can be simultaneously at this time
Microswitch 336 and pressure upper air valve 35 and lower air valve 4 are closed, makes air valve opening that the gas outside box be allowed to be able to enter crisper
In body 2.
The above embodiment is a preferred embodiment of the present invention, but embodiments of the present invention are not by above-described embodiment
Limitation, other any changes, modifications, substitutions, combinations, simplifications made without departing from the spirit and principles of the present invention,
It should be equivalent substitute mode, be included within the scope of the present invention.
