The specific embodiment

The following stated is merely the preferred embodiment of the utility model, does not therefore limit the protection domain of the utility model.

Embodiment sees Fig. 1 to shown in Figure 6, and two buckle-type vacuum crispers comprise base 1, box body 2 and loam cake 4, and base 1 upper fixed has box body 2.Between base 1 and the box body 2 vacuum pump 23 is set, obviously, leaves certain space between the bottom of box body 2 and the base 1.Box body 2 is provided with two relative buckles 8, and buckle 8 is fastened on loam cake 4 on the

box body

2, and 4 of box body 2 and loam cakes are provided with seal ring 3, good sealing effect.

See shown in Figure 2ly, the bottom of box body 2 and base 1 are provided with vacuum pump 23, the battery case 21 that also is provided with, surface-mounted integrated circuit 22, baroswitch 24, aspirating hole 25.Wherein, battery case 21 is connected with surface-mounted integrated circuit 22, and surface-mounted integrated circuit 22 is connected with vacuum pump 23, and aspirating hole 25 matches with vacuum pump 23.That is: placed after the battery in the battery case 21, for vacuum pump 23 and surface-mounted integrated circuit 22 provide working power.The open and close of surface-mounted integrated circuit 22 control vacuum pumps 23.Vacuum pump 23 vacuumizes through the inside of 25 pairs of box bodys 2 of aspirating hole.Baroswitch 24 matches with surface-mounted integrated circuit 22, and baroswitch 24 perception box bodys 2 in-to-in degree of vacuum are transmitted to surface-mounted integrated circuit 22 with signal then.That is: when the degree of vacuum in the box body 2 can not get requiring, baroswitch 24 sent the signal that starts vacuum pump 23 to surface-mounted integrated circuit 22, and vacuum pump 23 is opened.When the degree of vacuum in the box body 2 reached requirement, baroswitch 24 sent the signal of cutting out vacuum pump 23 to surface-mounted integrated circuit 22, and vacuum pump 23 is closed.
