The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
As shown in Figure 1 and Figure 2, vacuum crisper comprises the box body 1 and the lid 3 that can fasten mutually, be provided with seal ring 2 between box body 1 and the lid 3, on lid 3, be provided with knob 4, the outer periphery of knob 4 is provided with three button bit posts 5, and the inner peripheral that is used to hold the mounting hole 30 of knob 4 on the lid 3 is provided with and button bit post 5 corresponding sliding-rail grooves 6; The lower end of knob 4 is provided with three sphere plugs 17, be provided with stage clip 18 between knob 4 and the sphere plug 17, the bottom that is used to hold the mounting hole 30 of knob on the lid 3 be provided with three with sphere plug 17 cooresponding holes 16, wherein at least one hole is through hole and communicates with box body 1, is provided with venting flexible glue plug 15 in the through hole 16; Lid 3 is provided with the aspirating hole that communicates with box body 1, and aspirating hole is provided with aspirating hole plug 12, and the edge 13 of aspirating hole plug is can be out of shape up and down laminar.One side of knob 4 is fixed with torsion spring 19, and the other end of torsion spring 19 is hooked on the button bit of lid 3.On lid, also be provided with an assembly opening 26, be provided with the air bag 24 that to go up lower compression in the assembly opening 26, the inner chamber of air bag 24 is communicated with box body 1, the top of air bag 24 is fixed with endless drive part 22, Transmission 22 tops are provided with degree of vacuum display panel 20, two salient points 23 on the Transmission 22 are stuck in the plug helix 21 on the degree of vacuum display panel 20, and degree of vacuum display panel 20 is marked with atmospheric pressure value scale 25.Be provided with transparency display window 9 above degree of vacuum display panel 20, the axial restraint of transparency display window 9 has date ring 7 and month to encircle 28, and a side of transparency display window 9 is provided with date arrow 10.On date ring 7, be provided with screens 8, and on lid 3, encircle 7 cooresponding positions and be provided with 31 branch checkerwork cells 11 with the date.
Before vacuumizing, seal ring 2 packed into to be placed on the box body 1 in lid 3 respective grooves again, and knob 4 inserts in lids 1 respective aperture 30, and three uniform button bit posts 5 stretch into corresponding three sliding-rail grooves 6 on the lid 3 on the knob 4.Clockwise rotate knob 4, three uniform on the knob 4 sphere plugs 17 are sunk in corresponding three holes 16 on the lid 3, sphere plug 17 compresses with stage clip 18.Wherein two holes are blind hole, and a hole is a through hole, in venting flexible glue plug 15 is housed.So, the sealing surface on the sphere plug 17 overlaps with the sealing surface of air bleed hole plug 15, and with stage clip 18 compress make it the sealing.Therefore sphere plug 17 sinks in the lid 3 corresponding holes 16 and with stage clip 18 and compresses the time, and plays positioning action, leaks gas to avoid knob 4 freely to rotate.
When vacuumizing, because of aspirating hole plug 12 top air pressure are lower than its below air pressure, this pressure reduction makes the seal strip edge 13 on the aspirating hole plug 12 upwarp distortion and causes path 14 conductings of bleeding.Vacuum pump 29 is with 14 extractions along the path of air in the box body 1.
Finish when vacuumizing, vacuum pump 29 quits work, and this moment, aspirating hole plug 12 top air pressure were higher than its below air pressure.This pressure reduction makes the seal strip edge 13 on the aspirating hole plug 12 recover shape and be compressed its sealing surface by barometric pressure, closes and cause ventilation path 14.
During venting, knob 4 is clockwise rotated, make slip away air bleed hole plug 15 of sphere plug 17 realize venting, box inner and outer air pressure difference is disappeared.Aspirating hole sealing member 12 no longer is subjected to gas pressure, and its shape is in free state.Rotate counterclockwise knob 4 this moment, makes the button bit post 5 on the knob 4 recess lid 3 along the sliding-rail groove on the lid 36.
After the venting, utilize the effect of torsion spring 19 to make knob 4 self-returns, sphere plug 17 is sliding automatically to be back to air bleed hole plug 15 positions to seal air bleed hole and make, and makes crisper be in state to be bled.During torsion spring 19 free states, an end is fixed on the knob 4, and the torsion spring clasp of the other end colludes a button bit on lid 3.During knob 4 clickwises, the clasp that drives on the torsion spring 19 clockwise rotates, and makes clasp be subjected to antagonistic force, when torsion disappears, because of the effect of torsion spring 19 shape restoring forces, drives knob 4 self-returns.
Air bag 24 inner chambers and 1 interior connection of box body, Transmission 22 is connected in air bag 24 tops.Being symmetricly set in two salient points 23 on the Transmission 22 is stuck in the plug helix 21 on the degree of vacuum display panel 20.In the vacuum, box body 1 internal gas pressure reduces, and external atmosphere pressure to lower compression, move down thereby drive Transmission 22, and two salient points 23 on the Transmission 22 drives air bag 24 degree of vacuum display panel 20 around rotation by plug helix 21.Otherwise, when degree of vacuum in the box body 1 reduces, can make degree of vacuum display panel 20 backward rotation by aforementioned structure.Degree of vacuum display panel 20 is marked with atmospheric pressure value scale 25.Can see through the transparency display window 9 that places display panel 20 tops and observe real-time degree of vacuum.
Encircle 28 o'clock drive dates ring 7 month for avoiding rotating, and make it indication accurately, on date ring 7, be provided with screens 8, correspondingly on lid 3, be provided with 31 branch checkerwork cells 11.This structure can make rotates the date and encircles at 7 o'clock and feel to have lattice effect clearly.
