Wet vacuum sealing device and vacuum sealer

Abstract

A wet vacuum sealing device, includes a vacuum chamber provided with a vacuum joint, a vacuum pump connected to the vacuum joint, a solenoid valve with outlets respectively connected to the vacuum joint and the vacuum pump, and an inlet connected to an outside to allow air exchange, a heat sealing module arranged on a side of the vacuum chamber, and a control module electrically connected to the vacuum pump, the solenoid valve, and the heat sealing module. When the vacuum pump vacuums the vacuum chamber for a predetermined period of time, the solenoid valve switches states to make an air pressure inside the vacuum chamber close to an atmospheric pressure of the outside.

What is claimed is: 
     
         1 . A wet vacuum sealing device, comprising:
 a vacuum chamber provided with a vacuum joint;   a vacuum pump connected to the vacuum joint;   a solenoid valve, wherein outlets of the solenoid valve are respectively connected to the vacuum joint and the vacuum pump, and an inlet of the solenoid valve is connected to an outside to allow air exchange;   a heat sealing module arranged on a side of the vacuum chamber; and   a control module electrically connected to the vacuum pump, the solenoid valve, and the heat sealing module;   wherein when the vacuum pump vacuums the vacuum chamber for a predetermined period of time, the solenoid valve switches states to cause an air pressure inside the vacuum chamber to be close to an outside atmospheric pressure.   
     
     
         2 . The wet vacuum sealing device according to  claim 1 , wherein the solenoid valve is a normally closed solenoid valve. 
     
     
         3 . The wet vacuum sealing device according to  claim 1 , further comprising an electronic pressure gauge connected to the vacuum chamber, and the electronic pressure gauge is electrically connected to the control module. 
     
     
         4 . A vacuum sealer comprising the wet vacuum sealing device according to  claim 1 , wherein the vacuum sealer further comprises a sealer main body and an upper cover. 
     
     
         5 . A vacuum sealer comprising the wet vacuum sealing device according to  claim 2 , wherein the vacuum sealer further comprises a sealer main body and an upper cover. 
     
     
         6 . A vacuum sealer comprising the wet vacuum sealing device according to  claim 3 , wherein the vacuum sealer further comprises a sealer main body and an upper cover.
