Description

Handheld formaldehyde testing device Technical Field The invention relates to the technical field of testers, in particular to a handheld formaldehyde testing device. Background The new energy battery fire-resistant cover is a passive safety protection component which is specially applied to new energy automobiles (such as electric automobiles and electric buses) and energy storage systems. The battery pack of the new energy automobile faces safety challenges such as physical impact, thermal runaway, environmental erosion and the like in operation, and the outer wall of the battery pack often wraps a fire-resistant cover made of three-in-one blending of para-aramid, meta-aramid and flame-retardant cotton in order to provide physical protection, prevent thermal runaway from spreading and resist environmental erosion. In the production process of preparing the fire-resistant cover of the new energy battery by blending para-aramid fiber, meta-aramid fiber and fire-resistant cotton, part of fire-resistant cotton may adopt formaldehyde-containing fire retardant (such as urea-formaldehyde resin) and free formaldehyde may be released in the processing process, formaldehyde pollution may be introduced if formaldehyde-containing adhesive (such as urea-formaldehyde resin adhesive) is used in the blending process, and meanwhile, formaldehyde may be released if auxiliary materials such as dye, waterproofing agent and the like contain aldehydes, so that a processor needs to regularly use a handheld formaldehyde tester to test formaldehyde in the environment. The present patent with publication number CN211402317U discloses a formaldehyde tester, including formaldehyde tester body, the left top fixedly connected with stopper of formaldehyde tester body, the inside slidable mounting of stopper has the regulating plate, the top fixedly connected with dust guard of regulating plate, the left bottom fixedly connected with of regulating plate adjusts the head, the right side fixedly connected with cleaning assembly of dust guard bottom. Through formaldehyde tester body, stopper, regulating plate, dust guard, adjusting head and clean subassembly's setting, solved current domestic formaldehyde detector and be inconvenient for daily observation use, put and fall ash easily and not being concerned with at the desktop, reduced practical effect to the top does not possess dustproof effect, leads to detecting the mouth easily and is piled up by the dust and influence use problem, this formaldehyde tester possesses the advantage of being convenient for daily observation and dustproof, has improved stability in use. However, the formaldehyde tester still has the following problems in the actual use process: When using formaldehyde testers in a blend processing scenario, it is often necessary to leave them in a specific area for 5 to 10 minutes to complete the test, during which time workers often need to handle other procedures at the same time, and it is difficult to continue the hand-held equipment, so placement of the instrument becomes a practical problem.
