Vacuumizing device and vacuumizing container

Abstract

The invention relates to a vacuumizing device. The device comprises a cover body, a decoration body, a key, a piston and a key cover. The cover body comprises a base part and a concave part. The concave part protrudes upwards to form a supporting part. A first containing groove is formed between the supporting part and the concave part. A second containing groove is formed in the supporting part. The decoration body is contained in the first containing groove. The key is accommodated in an inner cavity of the decoration body and can move up and down. A key elastic piece is arranged on the supporting part in a sleeving mode. The lower portion of the piston is contained in the second containing groove, and the upper portion of the piston is contained in an inner cavity of the key and can move up and down. The key cover is arranged above the key, the key is fixedly connected with the key cover, and the key, the piston and the key cover synchronously move up and down. A first cavity is formed between a container body and the cover body, and a second cavity is formed between the piston and the bottom wall of the second containing groove. The bottom wall of the second containing groove is provided with a normally-closed exhaust hole, and the bottom wall of the piston is provided with a normally-closed exhaust hole. The vacuumizing device has the beneficial effects that vacuumizing, pressure maintaining and air inflation are realized by rotating or pressing the key cover, and the operation and the carrying are convenient.

Description

technical field [0001] The invention relates to the technical field of vacuuming devices, in particular to a vacuuming device and a vacuuming container. Background technique [0002] The vacuum device is used in various occasions that require a vacuum environment such as food preservation and clothing storage. At present, it is generally necessary to equip the vacuum device with auxiliary tools such as an air pump to extract the gas inside the vacuum device to form a vacuum environment. When using it, it is necessary to connect the auxiliary tool to the vacuum device first, and then carry out the vacuuming operation. The loading and unloading process is relatively cumbersome; it takes a lot of effort to form a vacuum environment in the device when vacuuming, which is time-consuming and laborious; the volume of the auxiliary tool is relatively large. Large, not easy to carry and store; after the auxiliary tool is lost or damaged, the vacuuming work cannot be continued. Theref...
