AI Technical Summary
Existing vacuum low-temperature preservation machines are prone to generating negative pressure when opened, making operation inconvenient and making it difficult to intuitively understand the leakage situation, thus affecting the storage effect.
A gas replenishment valve and a pressure sensor are installed on the vacuum low-temperature preservation machine. The gas replenishment valve introduces external gas to reduce the negative pressure before the sealing door is opened. The pressure sensor detects the pressure and processes the data through a microprocessor, which then displays the data on the screen to ensure data accuracy.
The easy opening of the sealed door improves operational convenience, and data comparison ensures the accuracy of air pressure detection, thus enhancing storage efficiency.
