The invention discloses a portable harmful gas alarm device comprising a hand grip, wherein the hand grip is in communication with a connecting cylinder that is in communication with a storage cylinder; a driving cavity, a buffer cavity and a storage cavity are respectively arranged in the hand grip, the connecting cylinder and the storage cylinder; one end of the driving cavity is provided with an alarm, cylinders are symmetrically arranged in the driving cavity, and the free ends of the cylinders are connected to a first buffer block. The portable harmful gas alarm device provided by the invention is directly taken by the hand grip, and is small in structure, convenient to carry and manually taken. The formaldehyde sensor can extend out of the storage cavity when detecting and retract tothe storage cavity at the end of the detection, thereby realizing the protection effect on the device. During formaldehyde detection and alarm, the free end of the cylinder is connected with to firstbuffer block by starting the cylinder, the first buffer block moves to the right by the cooperation of a limit groove and a limit wheel, the second buffer block then moves to the right, the first buffer spring is compressed, and the formaldehyde sensor extends out of the storage cavity.
Description
technical field [0001] The invention relates to the technical field of harmful gas alarms, in particular to a portable harmful gas alarm device. Background technique [0002] Formaldehyde is a colorless, water-soluble liquid that is highly volatile and has a pungent odor. Indoor formaldehyde mainly comes from building materials, furniture, wood-based panels, various adhesive coatings and synthetic textiles, etc. The amount of formaldehyde is very small, but smoking is an important source of formaldehyde emission. It has been determined that each cigarette can emit about 2.4 mg of formaldehyde, and the concentration of formaldehyde in the smoke directly inhaled from cigarettes may exceed the warning concentration by more than 400 times. Urea-formaldehyde resin is usually used as an adhesive in the production of wood-based panels and their furniture, which may be the largest source of formaldehyde emissions. Formaldehyde can be adsorbed and enriched by indoor high specific su...
