Further, described suction nozzle includes that sheath, described vacuum pump are electric vacuum pumps, and described electric vacuum pump includes that micro machine and microswitch, described micro machine are connected with described microswitch, and described microswitch contacts with described sheath.
Further, described vacuum pump also includes that sensor, described sensor are connected with described microswitch.
Further, the border, top of described vacuum pump arranges positioning convex, and described top of closure arranges detent, described positioning convex and described detent in described aspirating hole border and matches each other.
Further, described lid arrange Vacuum solutions except key and venting stifled, it is to isolate described top of closure and the mobiles of bottom that described venting is blocked up, and described Vacuum solutions is except key and described venting is stifled contacts.
Further, also including protection cap, described protection cap is distributed passage, described protection cap is arranged on described lid bottom, covers described check valve.
Further, described protection cap arranging protection cap buckle, described protection cap is arranged on described lid by described protection cap buckle.
Further, also include that cradle, described cradle are connected with described electric vacuum pump.
Further, also include that sucker, the bottom of described sucker are fixed with described cradle.
Further, described electric vacuum pump is provided with charging socket.
Have employed the technical solution of the utility model, owing to having only to a fresh-keeping cover, it is possible to be used together with domestic container, thus reduce cost, simultaneously because extract air by electric vacuum pump, and electric vacuum pump can separate with fresh-keeping cover, thus facilitates use.

Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
In a detailed description of the invention of the present utility model, this fresh-keeping cover includes lid and vacuum pump.Fig. 1 is the top front face schematic diagram of lid in this utility model detailed description of the invention；Fig. 2 is the bottom front schematic view of lid in this utility model detailed description of the invention.As depicted in figs. 1 and 2, this lid 1 bottom is provided with layer of silica gel 11, is provided with the aspirating hole 12 and check valve being connected together in the middle of lid, and one end of aspirating hole is stretched out outside lid, and one end of check valve is positioned at inside lid.
Fig. 3 is the schematic perspective view of this utility model detailed description of the invention intermediate pump.As it is shown on figure 3, this vacuum pump 2 is electric vacuum pump, electric vacuum pump is provided with suction nozzle 21, micro machine, microswitch and sensor, suction nozzle periphery is provided with sheath, this sheath is made up of plastic material, and micro machine is connected with microswitch, and sensor is connected with microswitch.
The border, top of electric vacuum pump arranges positioning convex 22, and top of closure arranges detent 13, positioning convex and detent in aspirating hole border and matches each other with in size in position.
Suction nozzle the most also matches each other with aspirating hole.
When using this fresh-keeping cover, first lid is placed on container, on such as bowl, owing to lid bottom is provided with layer of silica gel, there is certain elasticity, so lid is readily formed identical with the edge of container.While pressing lid, the top of electric vacuum pump is directed at lid, owing to the top of this electric vacuum pump is provided with positioning convex, accordingly, top of closure is provided with detent, so after positioning convex enters detent, the suction nozzle of electric vacuum pump the most just connects with the aspirating hole on lid.
When the suction nozzle of electric vacuum pump connects with the aspirating hole on lid; suction nozzle is to insert the state within aspirating hole; aspirating hole top can contact with the sheath of suction nozzle; and press suction nozzle boot; microswitch starts in the top pressure of suction nozzle protection set; triggering micro machine runs; start to extract lid and the air in the space of container formation; when air is drawn into a certain degree of vacuum; sensor sends signal to microswitch, disconnects microswitch, thus closes micro machine; extraction process completes, and at this moment can take down electric vacuum pump.Owing to inside is near vacuum state, outside pressure extrusion lid and container, layer of silica gel between the two is squeezed, and seal degree is more preferable.
Except key 14 and exitting stifled as it is shown in figure 1, lid is additionally provided with Vacuum solutions, it is isolation top of closure and the mobiles of bottom that this venting is blocked up, and Vacuum solutions is blocked up except key and venting and contacted.When it is desired to open the lid, pressing Vacuum solutions is blocked up except key will back down venting except key, this Vacuum solutions, so that top of closure and bottom are through, air enters the space between lid and container, and vacuum state releases, and lid just can easily open.
As in figure 2 it is shown, lid also includes protection cap 15, this protection cap being distributed passage 16, protection cap arranges protection cap buckle 17, protection cap is arranged on inside lid bottom, i.e. lid by protection cap buckle, covers check valve.This set is to prevent from extracting during air; food crumbs in container is inhaled in check valve, thus blocks check valve, and when food crumbs is attached to the passage of protection cap; protection cap can be taken off from lid flushing, it is ensured that lid clean.
Electric vacuum pump has two kinds of charging modes, the first as shown in Figure 4, Fig. 4 is this utility model detailed description of the invention intermediate pump charger schematic diagram.This fresh-keeping cover also includes cradle 3 and sucker 4, when electric vacuum pump needs charging, can be placed on cradle, charging contact is located on the inside and outside wall of the protruding annulus of cradle, is provided with groove in the bottom of electric vacuum pump, the round wall of two of groove is provided with electrode, directly electric vacuum pump is coordinated with cradle during charging, so use and easily, and suction nozzle can be provided with on cradle dodge hole, it is greater than the circular hole of suction nozzle, it is therefore an objective to will not encounter when charging.Additionally cradle is fixed on the bottom of sucker, and cradle is fixed on certain position by sucker, and electric vacuum pump is charged again, has been also convenient for operation.
The second is to be provided with charging socket on electric vacuum pump, directly can be powered by outer low pressure power supply.
In above-mentioned detailed description of the invention, owing to having only to a fresh-keeping cover, it is possible to being used together with domestic container, thus reduce cost, simultaneously because extract air by electric vacuum pump, and electric vacuum pump can separate with fresh-keeping cover, thus facilitates use.
The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any it is familiar with the people of this technology in the technical scope disclosed by this utility model; the change that can readily occur in or replacement, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with scope of the claims.
