Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, cartridge device to refrigerator vacuum fresh-keeping bag extracting vacuum of the present utility model, comprise pedestal 1, cavity 10 is provided with in pedestal 1, cavity 10 side is connected with the extraction junction block 6 of the extraction pipeline (i.e. vacuum lead) for connecting vacuum pump, extracts the sidewall that junction block 6 stretches out pedestal 1;
Described cavity 10 is connected with suction nozzle 5 downwards, and suction nozzle 5 stretches out pedestal 1 downwards; Actuating plate 2 is hinged with pedestal 1 top extracting junction block 6 homonymy, pedestal boss 11 is provided with to downward-extension bottom the pedestal 1 of opposite side, the pedestal 1 at pedestal boss 11 place is provided with the groove 12 of up/down perforation, pedestal boss 11 is hinged with L shape pressure flap, L shape pressure flap comprises the riser 3 and transverse slat 13 that are fixed together, riser 3 is positioned at described groove 12, and riser 3 top is bent to form pressure-bearing portion 14 to the direction extracting junction block 6 side; When riser 3 is in vertical state, the top in pressure-bearing portion 14 contacts with the actuating plate 2 under horizontality; Wherein, groove 12 provides rotation space for riser 3.
The transverse slat 13 of L shape pressure flap extends to extraction junction block 6 side, and when riser 3 is in vertical state, transverse slat 13 is adjacent with the suction nozzle 5 above it; Described groove 12 closes on the sidewall extracting junction block 6 and is provided with spring groove 15, is provided with stage clip 4 in spring groove 15, and described riser 3 top is pressed on the sidewall of described groove 12 opposite side by stage clip 4.
Pedestal 1 above described cavity 10 is provided with reseting groove 16, pressure release valve shaft 7 is provided with in reseting groove 16, pressure release valve shaft 7 passes downwardly through connecting bore 17 and stretches into described cavity 10, bearing fit between pressure release valve shaft 7 and connecting bore 17 and be provided with pressure release gap (pressure release gap is less, figure do not show) therebetween; Pressure release valve shaft 7 lower end radial protrusion is provided with lower bulge 18, and the pressure release valve shaft 7 in the middle part of reseting groove 16 is furnished with spring press-cover 19, and the pressure release valve shaft 7 between the bottom land of spring press-cover 19 and reseting groove 16 is arranged with retracing spring 8; Retracing spring 8 upwards top pressure spring gland 19 make lower bulge 18 be pressed on cavity 10 roof and block connecting bore 17 under free state, thus prevent because of pressure release valve shaft 7 and connecting bore 17 is poorly sealed cause vacuumizing time air enter cavity 10 by the pressure release gap between connecting bore 17 and pressure release valve shaft 7.
The part that described suction nozzle 5 stretches out pedestal 1 is downwards lower large little tubaeform.
When vacuumizing, extraction junction block 6 is connected with the extraction pipeline (i.e. vacuum lead) of external vacuum pump, then operator manually presses actuating plate 2, when actuating plate 2 is rotated down, its right part presses the pressure-bearing portion 14 that L shape pressure flap tilts downwards, thus makes L shape press flap entirety to be rotated down left.Riser 3 is compression press spring 4 when rotated, and transverse slat 13 is when rotated away from suction nozzle 5, thus vacuum fresh-keeping bag is placed between transverse slat 13 and suction nozzle 5 by convenient operation person.When placing vacuum fresh-keeping bag, freshness protection package is provided with one of check valve facing to suction nozzle 5, check valve is adjacent to suction nozzle 5 simultaneously.When actuating plate 2 is rotated down, its left part presses pressure release valve shaft 7 downwards.
After putting vacuum fresh-keeping bag well, unclamp actuating plate 2, under the effect of stage clip 4, the contrarotation of pressure flap resets, and pressure-bearing portion 14 is jack-up actuating plate 2 upwards, and actuating plate 2 is also resetted; Pressure flap is when spinning reduction, and transverse slat 13 close to suction nozzle 5, thus makes transverse slat 13 and suction nozzle 5 clamp vacuum fresh-keeping bag, now just can start extracting vacuum; The negative pressure that vacuum pump provides arrives vacuum fresh-keeping bag by extracting junction block 6, cavity 10 and suction nozzle 5.
After vacuumizing, press actuating plate 2, pressure release valve shaft 7 declines, and then air enters cavity 10 by described pressure release gap, and the vacuum in cavity 10 is released.While pressure release valve shaft 7 declines, pressure flap is subject to the pressure of actuating plate 2 and rotates, and make transverse slat 13 when rotated away from suction nozzle 5, thus vacuum fresh-keeping bag is taken off from suction nozzle 5 by convenient operation person, is put into required place.
After unclamping actuating plate 2, under the effect of the retracing spring 8 on pressure release valve shaft 7, pressure release valve shaft 7 gets back to initial position, holds out against the roof of cavity 10.Meanwhile, press down flap get back to initial position in the effect of stage clip 4, the riser 3 of pressure flap holds out against the sidewall of the groove 12 of stage clip 4 opposite side.
Vacuum fresh-keeping bag has the opening that can repeat to open, therefore can repeated usage.Whole device can be arranged on refrigerator body inside, also can be arranged on refrigerator body outside.
The advantage of present embodiment is, simple to operation, can carry out clamping and extracting vacuum by fast speed to vacuum fresh-keeping bag, user-friendly, and vacuum fresh-keeping bag is reusable, and the feature of environmental protection is good.
Above embodiment is the unrestricted the technical solution of the utility model in order to explanation only, although be described in detail the utility model with reference to above-described embodiment, those of ordinary skill in the art is to be understood that: still can modify to the utility model or equivalent replacement, and not departing from any modification or partial replacement of spirit and scope of the present utility model, it all should be encompassed in the middle of right of the present utility model.
