[0006] According to the exhaust structure of the packing box, the side end of the storage box is fixedly connected with a first lock catch frame, and the first lock catch frame is located at the upper end of the storage box. It is favorable for the stable clamping of the main cover to prevent leakage.

[0007] According to the exhaust structure of the packing box, the lower end of the main cover is fixedly connected with a second lock catch frame, and the second lock catch frame is connected with the first lock catch frame. It is favorable for the stable clamping of the main cover to prevent leakage.

[0008] The utility model discloses a kind of exhaust structures of packing box, the upper end of the main cover is fixedly connected with third lock catch frame.

[0009] The utility model discloses a kind of exhaust structures of packing box, the lower end of the vice cover is fixedly connected with fourth lock catch frame, and the fourth lock catch frame is connected with third lock catch frame.The stable clamping of vice cover is beneficial, prevent leakage.

[0010] Beneficial effects:

[0011] Compared with prior art, the exhaust structure of the packing box, by box cover, vice cover, outer exhaust hole and inner exhaust hole constitute double exhaust structure, gas in storage box can be discharged, and the leakage of liquid can be avoided, solve the problem that packing box exhaust sealing is difficult to take into account.
