Description

Technical Field

[0001] The utility model discloses a vacuum drying box with a vacuum pumping function, belonging to the technical field of vacuum drying boxes. Background Art

[0002] The vacuum drying oven is specially designed for drying heat-sensitive, easily decomposable and easily oxidized materials. The inside of the oven is divided into several layers by the heating plate, and then some heating medium that can increase the temperature is introduced into the heating plate, and objects are placed on the surface of the heating plate, so as to achieve rapid drying of the objects. In order to make the vacuum drying oven dry stably, inert gas is also introduced.

[0003] Chinese patent number: CN220338908U, mentions a vacuum drying oven with uniform flat plate drying function, which heats the inert gas introduced into the vacuum drying oven through a heating plate, starts the fan, and uses the heated inert gas to dry the objects on the drying plate. When the gas flows out from the top of the drying rack, it returns to the bottom of the drying rack along the air guide plate and is absorbed by the fan again to dry the objects again. This cycle can make use of the heated inert gas, improve utilization, reduce consumption, and heat evenly. However, when this device dries the object, the object is stationary, the heating rate is slow, and the temperature inside the device is high after heating, which makes it easy to get burned when the object is picked up. Now there is an urgent need for a vacuum drying oven with a vacuuming function to solve the above problems. Utility Model Content
