A display screen 120 is mounted on the upper half of the front surface of the housing body 100, and a mechanical button 130 is mounted on the lower half of the front surface of the housing body 100.

[0019] A data interface 101 is provided between the mechanical button 130 and the display screen 120. A gas analysis module is mounted on a circuit board within the housing 100. The display screen 120 and the mechanical button 130 are electrically connected to the circuit board via wires. Two heat dissipation grilles 150 are symmetrically mounted on the upper edge of the right surface of the housing 100.

[0020] A door panel 160 is hingedly connected to the lower half of the right side surface of the housing body 100. A power module is installed on the lower edge of the rear side surface of the housing body 100. A charging interface is provided on the surface of the power module, and the power module is electrically connected to the circuit board via wires.

[0021] During use, when the user needs to move the device, he only needs to hold the two handles 110, and then the entire device can be moved.
