Pointer 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 positioned at 16 lower section of vacuum state indication key in keyseat 9
19, 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 press
Contracting sponge 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
When vacuum state, vacuum state indication key 16 bounces back downwards, when crisper is in non-vacuum, vacuum state indication key 16
It raises upward under 19 elastic reaction of sponge.
The working principle of the utility model 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.
Above-described embodiment is the preferable embodiment of the utility model, but the embodiments of the present invention is not by above-mentioned
The limitation of embodiment, it is made under other any spiritual essence and principles without departing from the utility model to change, modify, replacing
In generation, simplifies combination, should be equivalent substitute mode, is included within the protection scope of the utility model.
