Description of drawings
Fig. 1 is perspective view of the present utility model;
Fig. 2 is section-drawing of the present utility model;
Fig. 3 is the structural representation of seal ring in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is made detailed explanation.
As shown in Figure 1 and Figure 2, the vacuum fresh-keeping pot that the utility model provides comprises tank body 1 and spiral-lock at the top cover 2 of tank body 1 open end, and top cover 2 comprises top cover body 21, seal ring 22, air valve 23, dat recorder dish 24 and date selection sheet 25.
The end face central part of top cover body 21 is provided with a pit, be provided with a bleeding point 213 that communicates with tank body 1 inner chamber in pit, bleeding point 213 is complementary with vacuum extractor, can utilize vacuum extractor that the air in tank body 1 is extracted out, air valve 23 is arranged in bleeding point 213, one-way sealing after being used for realizing vacuumizing prevents that ambient atmos from entering tank body 1.
The structure of seal ring 22 as shown in Figure 3, the upper and lower end of seal ring 22 is respectively equipped with the second annular lip 221 and the 3rd annular lip 222, and the external diameter of the second annular lip 221 is greater than the external diameter of tank body 1, the external diameter of the 3rd annular lip 222 is slightly larger than the internal diameter of tank body 1, the inwall of seal ring 22 is provided with annular groove 223, the first annular ridge 212 is installed in annular groove 223, thereby seal ring 22 is fixed on the lateral surface of top cover body 21.When spiral-lock upper top cover 2, the second annular lip 221 is pressed between top cover body 21 and tank body 1 open end, realized the first sealing, simultaneously, the 3rd annular lip 222 is subjected to the extruding of tank body 1 inwall, is close on the inwall of tank body 1, has realized the second sealing, and when utilizing top cover 2 carrying tank body 1 this moment, tank body 1 can not come off.
see also again Fig. 1, Fig. 2, the inwall of bleeding point 213 is provided with Fourth Ring shape fin 214, the inner end surface of Fourth Ring shape fin 214 is provided with the annular riser 215 to downward-extension, annular riser 215 is provided with a plurality of radial direction through hole 216, air valve 23 is made by soft rubber, has an air valve body cylindraceous, the outside face of air valve body is provided with, lower annular lip 231, 232, the end face of lower annular lip 232 is resisted against on the bottom surface of annular riser 215, the bottom surface of upper annular lip 231 is resisted against on shape fin 214 end faces of Fourth Ring, the inwall of air valve body is provided with seal membrane 233, seal membrane 233 is the dome shape of epirelief.When vacuumizing, the gap of air between radial direction through hole 216 and upper annular lip 231 and Fourth Ring shape fin 214 in tank body 1 enters vacuum extractor, vacuumize stop after, under the effect of tank body 1 interior negative pressure, the bottom surface of upper annular lip 231 is pressed on the end face of Fourth Ring shape fin 214, has realized one-way sealing.Simultaneously, under the effect of negative pressure, seal membrane 233 can sink, can know by the degree that seal membrane 233 sink the degree of vacuum that tank body 1 is interior, seal membrane 233 sink deeplyer, show that the degree of vacuum in tank body 1 is higher, when seal membrane 233 restores to the original state, show in tank body 1 it has been no longer vacuum state.When needs were opened top cover 2, side direction was stirred air valve 23, made annular lip 231 leave Fourth Ring shape fin 214, so outside air enters in tank body 1 through the gap both, thereby removed the interior vacuum state of tank body 1.
Above introduction is to carry out as an example of the tank body of barrel-shaped structure example, obviously, the technical scheme that the utility model provides is equally applicable to the tank body of square or other polymorphic structures, for the tank structure of other shapes, only needs that the shape of top cover is carried out corresponding coupling design and gets final product.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection domain of the present utility model.
