Referring to fig. 1-4, an ear-buckle-connection-free preservation box comprises a box body 1 and a box cover 2, wherein a sinking groove 3 for inserting an air suction tube is arranged on the box cover 2, an air exhaust hole communicated with the interior of the box body 1 is arranged on the bottom surface of the sinking groove 3, a sealing plug 4 capable of floating up and down is arranged in the air exhaust hole, the sealing plug 4 comprises a cylindrical plug body 41, an upper plug 42 and a lower plug 43 which are respectively and correspondingly connected with the upper end and the lower end of the cylindrical plug body 41 in an integrated manner, a slit 5 for air to enter and exit is arranged between the outer wall of the cylindrical plug body 41 and the inner wall of the air exhaust hole, and the upper plug 42 and the lower plug 43 can float up and down along with the cylindrical plug body 4 to cyclically and alternately block the air exhaust hole.

The utility model discloses in, have a plurality of protruding muscle 44 of a body coupling on the outer wall of cylindricality cock body 41 respectively, a plurality of protruding muscle 44 is equidistant distribution along the periphery of cylindricality cock body 41, and with the inner wall looks butt in exhaust hole.

Therefore, in the process that the cylindrical plug body 41 floats up and down in the exhaust hole, the plurality of convex ribs 44 move up and down along the inner wall of the exhaust hole, and guide is provided for the up-and-down floating of the cylindrical plug body 41.

In the utility model, the cylindrical plug 41 has a hollow structure with a closed upper end and an open lower end.

Therefore, on the basis of ensuring sealing, the whole weight of the cylindrical plug body 41 can be effectively reduced, so that the cylindrical plug body can float up and down under the action of air pressure.

The utility model discloses in, be equipped with the ring groove 45 that can with the lower port looks joint of pump bowl on the outer wall of upper end cap 42.

Therefore, after the air pumping cylinder is inserted, the air pumping cylinder can be fixed in the sinking groove 3, and the operation of the air pumping cylinder is convenient.

The utility model discloses in, around the annular arch 6 that has a body coupling all around of the last port in exhaust hole on the bottom surface of heavy groove 3, the bottom surface of going up end cap 42 is equipped with the annular breach with the protruding 6 matched with of annular.

Therefore, when the bottom surface of the upper plug 42 is abutted against the upper edge of the exhaust hole, the annular protrusion 6 is just completely clamped into the annular gap, and after air suction is finished, negative pressure is generated in the box, so that the upper plug 42 is firmly adsorbed on the upper edge of the exhaust hole, and the sealing performance is improved.

The utility model discloses in, the position that is corresponding to the mouth edge of box body 1 is equipped with annular groove 7 around the bottom surface of lid 2, is equipped with sealing washer 8 in the annular groove 7.

Therefore, after air exhaust is finished, negative pressure is generated in the box, the box cover 2 is firmly adsorbed on the box body 1, and the sealing performance can be improved by arranging the sealing ring 8.

In the utility model, the box body 1 is made of glass, which is characterized by safety, environmental protection, good sealing property and freshness-keeping property, strong heat resistance and cold resistance, no peculiar smell, good abrasion resistance and heat resistance, etc.; the box cover 2 is made of plastic and has the characteristics of low cost, high hardness, good rigidity, strong stability, excellent mechanical property and heat resistance and the like.

The utility model discloses in, the material of sealing plug 4 is silica gel, has characteristics such as high temperature resistant, long service life, pliability are good, non-deformable.

The invention is further described below with reference to the accompanying drawings:

with the utility model discloses the pump bowl that the cooperation was used is including barrel 9, along the piston rod 10 that the inside of barrel 9 reciprocated to and connect in the piston 11 of piston rod 10 bottom. Wherein, the interior of the piston rod 10 is hollow, and the upper and lower ends of the side wall thereof are provided with an air inlet 12 and an air outlet (not shown in the figure, the same applies below) which are communicated with each other; the piston 11 is wedge-shaped with a thin top and a thick bottom.

When the air suction device is used, the air suction cylinder is inserted into the sinking groove 3, so that the inner edge of the lower port of the cylinder body 9 is clamped into the annular clamping groove 45.

Then, the piston rod 10 is lifted to drive the air at the lower end of the cylinder 9 to flow upwards, so as to drive the whole sealing plug 4 to float upwards, part of the air in the box body 1 flows out through the slit 5 and flows into the lower end of the cylinder 9 until the lower plug 43 is abutted against the lower edge of the exhaust hole, and the exhaust hole is plugged from the lower side.

Then, the piston rod 10 is pressed down, the air at the lower end of the cylinder 9 is compressed, the air pressure is increased, and under the action, on one hand, the whole sealing plug 4 floats downwards until the upper plug 42 is abutted against the upper edge of the exhaust hole, and the exhaust hole is blocked from the upper side. On the other hand, the compressed air presses the piston 11, so that the upper end of the piston 11 is contracted inward, and at this time, the air flows into the inside of the piston rod 10 through the air inlet 12 and is finally discharged through the air outlet at the upper end thereof.

The above process is repeated until the air in the box body 1 is basically pumped out.

After the air in the box body 1 is basically pumped out, namely after the air pumping is finished, negative pressure is formed in the box body 1, so that the upper plug 42 is firmly adsorbed on the upper edge of the exhaust hole under the action of the internal and external pressure difference, and the exhaust hole is blocked from the upper side; on the other hand, the box cover 2 is firmly adsorbed on the box body 1, the sealing connection between the box cover and the box body is realized, and the purpose of preservation is achieved.

When the box cover 2 needs to be opened, the sealing plug 4 is pulled up, so that the internal and external air pressures of the box body 1 are recovered to be consistent, the sealing connection relation between the box cover 2 and the box body 1 is released, and the box cover 2 can be opened.

Although the present description is described in terms of embodiments, not every embodiment includes only a single embodiment, and such description is for clarity only, and those skilled in the art should be able to integrate the description as a whole, and the embodiments can be appropriately combined to form other embodiments as will be understood by those skilled in the art.

Therefore, the above description is only a preferred embodiment of the present application, and is not intended to limit the scope of the present application; all the equivalent changes made within the scope of the claims of the present application are the protection scope of the claims of the present application.
