Abstract

The invention discloses a vacuum packaging device based on rapid response to humidity changes. By installing a humidity sensor module at the bottom of the cabinet of the vacuum packaging device, the vacuum packaging device can detect the humidity of the gas environment during the working process. Changes, which play a very good role in protecting the normal operation of the vacuum packaging equipment; the humidity sensor module is creatively designed from the sensor's sensitive materials, manufacturing conditions, structure, etc., so that the response speed is fast and the sensitivity is greatly improved. The test has good repeatability, has produced unexpected technical effects, and has great market application prospects.

Description
