Alarm device for formaldehyde content detection

Abstract

The invention relates to an alarm device for formaldehyde content detection. The alarm device comprises a housing (1) and a power supply (11) connected to the inside of the housing (1). The housing is provided with an air inlet (4), the rear end of which is connected to an air pump (2). A switch of the air pump (2) is arranged at a left side of the housing (1). The housing (1) is internally equipped with a color comparator (5) connected to the air pump (2), a sensor connected to the color comparator (5), and a display (8), an indicator light (9), and an alarm (10) which are connected to the sensor (7). The housing further comprises a color comparison light source (6) arranged below the color comparator (5). Provided is the alarm device for formaldehyde content detection, which has a warning function and doesn't need help from professional individuals.

Description

technical field [0001] The invention belongs to gas alarm equipment, in particular to a formaldehyde content detection and alarm device. Background technique [0002] As we all know, formaldehyde is toxic, and its health hazards to the human body mainly include the following aspects: [0003] Stimulation: Mainly manifested as irritation to the skin and mucous membranes. Formaldehyde is a toxic substance in the protoplasm, which can be combined with proteins. When inhaled at high concentrations, severe respiratory edema will occur, which directly affects the normal progress of breathing; sensitization: direct contact with formaldehyde on the skin can cause allergic dermatitis, stains, and necrosis. Formaldehyde can induce bronchial asthma; mutagenic effect: high concentration formaldehyde is also a genotoxic substance. Animal experiments have shown that inhalation of high concentrations can cause nasopharyngeal tumors. Typical consequences: headache, dizziness, fatigue, na...

Problems solved by technology

[0005] Most of today's formaldehyde detectors are tested in the laboratory after air sampling, which not only has large errors, but also is inconvenient. The formaldehyde in the indoor air mainly comes from plywood, blockboard, medium density fiberboard and particle board used for interior decoration. Plates, the formaldehyde content in the air is high after the home is newly renovated. If the traditional method is used, it will not only have no alarm function but also cost a lot, and it is inconvenient to monitor the air quality in the home.
