▎ 摘　　要

NOVELTY - The device has a baffle plate (129) whose bottom end is fixedly connected with a box frame (110). A push rod (130) is fixedly connected to the left side of the baffle plate. The left end of the push rod extends through a first placement chamber (128) to the inside of the first placement chamber. A first moving plate (131) is provided on the left side of the first placement chamber. A second inner groove (132) is opened on the inner wall of the first placement chamber. A third spring is fixedly connected to the left side of the first moving plate. The left end of the third spring is fixedly connected with the inner wall of the second inner groove. The inside of the box frame is provided with a second storage compartment (134). A rubber plug (135) is inserted into the bottom end of the right side of the box frame. An adjustment mechanism (200) is installed inside the box frame. USE - Graphene material detection device. ADVANTAGE - The device is made difficult for users to leak formaldehyde during detection, protects the user health, and the user intuitively see the gap in the negative ion release performance between the graphene material and the comparative material. The users seamlessly connect the detection between graphene materials and contrast materials. No need for users to put in and take out graphene materials and contrast materials one by one for testing and comparison, which improves the testing efficiency of users. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an use method of the graphene material detection device. DESCRIPTION OF DRAWING(S) - The drawing shows a front sectional view of the graphene material detection device.
