Abstract
The utility model relates to a vacuum storage can, which comprises a can body with a cover, and a vacuum extracting device, wherein, the can body is arranged in a split mode. The cover is provided with a valve seat, the valve seat is provided with a vent hole, a bowl-shaped mouth down film sheet is covered on the vent hole, a film sheet fixing cover combined with the valve seat is arranged above the film sheet, the back of the film sheet is provided with a handle, the fixing cover is provided with a hole in which the handle can penetrate, and the lower edge of the fixing cover is also provided with a sealing ring. The vacuum extracting device comprises a piston bush and a piston, wherein, the piston bush is in the shape of a frustum of which the upper part is slightly thin, the lower part of the piston bush forms a gas sealing fit with the upper end of the valve seat, and the lower part of the piston is provided with a sealing ring. The utility model has the advantages of simple structure, long vacuum holding time, and more convenient operation.
Description
The utility model relates to a kind of vacuum canister seals.
Present vacuum canister seals, its check valve often are provided with vacuum extractor is whole, thereby the tank structure complexity, and then have hindered the setting that is beneficial to raising of vacuum holding time and the various convenient functional components that use.
The purpose of this utility model is to provide a kind of tank structure simple, the vacuum canister seals that the vacuum holding time is long.
The further purpose of the utility model is to be provided with and is beneficial to raising of vacuum holding time and the convenient functional component that uses, so that the vacuum canister seals that a kind of vacuum holding time is longer, use is convenient to be provided.
For achieving the above object, the utility model is by the following technical solutions: it comprises tank body and the vacuum extractor of establishing lid, described tank body and vacuum extractor split are provided with, the described valve seat that is covered with, valve seat is provided with air extractor vent, and the air extractor vent top covers the bowl-type diaphragm of mouth down, the diaphragm top is provided with the diaphragm fixed cap that combines with valve seat, the back side of diaphragm is provided with handle, and fixed cap is provided with the hole of passing for handle, and the lower edge of described lid also is provided with seal ring; Described vacuum extractor comprises piston bush and piston, and piston bush is the slightly thin taper type in top, and its underpart cooperates with valve seat upper end vapor seal, and lower part of piston is provided with seal ring.
Adopting above technical scheme simultaneously, the utility model also can be by the following technical solutions:
The center of described valve seat also is provided with air extractor vent, and the center of above-mentioned diaphragm is provided with radius stay, and radius stay penetrates this air extractor vent.
Above-mentioned handle is provided with in the back side of diaphragm off-center, and the described hole of passing for handle is a slotted hole.
The bottom of described valve seat is provided with sheath.
The upper edge of above-mentioned tank body is provided with stria.
Owing to adopted technique scheme, the utility model tank body and vacuum extractor split are provided with, and have simplified tank structure, adopt the leak tightness of diaphragm and seal ring sealing raising tank body to improve the vacuum holding time effectively; The setting of radius stay on the diaphragm further prevents the displacement of diaphragm, helps improving the vacuum holding time; The structure that handle is eccentric at the diaphragm back side to be provided with, the described hole of passing for handle is a slotted hole make before vacuumizing handle be in slotted hole away from the diaphragm center-side, when vacuumizing, handle is drawn close until running into to nearly center-side gradually, thereby this structure can play the effect that shows the state that vacuumizes; The sheath of valve seat bottom can prevent that the article in the jar from entering air extractor vent, influences vacuum and preserves; The stria of jar upper edge makes when vacuumizing, because pressure differential effect seal ring embeds stria, can further improve air-tightness.
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 is a generalized section of the present utility model.
With reference to accompanying drawing.The utility model comprises establishing and covers 1 tank body 2 and vacuum extractor 3, described tank body 2 and vacuum extractor 3 split settings, described lid 1 is provided with valve seat 6, the upper end of valve seat 6 is provided with sealing shroud 5, valve seat 6 is provided with air extractor vent 7, air extractor vent 7 tops cover the bowl-type diaphragm 8 of mouth down, diaphragm 8 tops are provided with the diaphragm fixed cap 9 that combines with valve seat 6, this combination can be buckled, the back side of diaphragm 8 is provided with handle 10, fixed cap 9 is provided with the hole of passing for handle 10 11, and the lower edge of described lid 1 also is provided with seal ring 12; Described vacuum extractor 3 comprises piston bush 13 and piston 14, and piston bush 13 is the slightly thin taper type in top, and its underpart is provided with the sealing shroud 15 that cooperates with above-mentioned sealing shroud 5 vapor seals, and the bottom of piston 14 is provided with seal ring 16.
The center of described valve seat 6 also can be provided with air extractor vent 7, and the center of above-mentioned diaphragm 8 is provided with radius stay 17, and radius stay 17 penetrates this air extractor vent 7.
Above-mentioned handle 10 can be in the eccentric setting in the back side of diaphragm 8, and the described hole of passing for handle 10 11 is slotted hole.
The bottom of described valve seat 6 can be provided with sheath 18, at this moment, on the adjacent wall of valve seat 6 and sheath 18 some projectioies 4 can be set, and just forms the slit so that air passes through like this between sheath 18 and valve seat wall.
The upper edge of above-mentioned tank body 2 is provided with stria 19.
