Detecting equipment for indoor formaldehyde

Abstract

The invention discloses detecting equipment for indoor formaldehyde. The detecting equipment comprises a formaldehyde sensor, a signal amplifier, an A / D (Analogue / Digital) converter, a display screen, a processor, an alarm and an air interchanger, wherein the formaldehyde sensor is used for acquiring indoor formaldehyde information and transmitting the formaldehyde information to the signal amplifier; the signal amplifier is used for receiving the formaldehyde information transmitted by the formaldehyde sensor, carrying out amplifying processing on the formaldehyde information and transmitting the amplified formaldehyde information to an A / D conversion module; the A / D conversion module is used for receiving the amplified formaldehyde information transmitted by the signal amplifier, converting the amplified formaldehyde information and transmitting the converted formaldehyde information to a digital signal processor; the processor is used for receiving a digital signal transmitted by the A / D converter, comparing the digital signal with a preset value, transmitting alarming information to the alarm and transmitting an air exchange instruction to the air interchanger when the digital signal exceeds a threshold H; the alarm is internally provided with a buzzer which is a pneumatic buzzer, and is used for for receiving alarming information transmitted by the processor; the air interchanger comprises an air inlet fan, an activated carbon net and an air outlet.

Description

technical field [0001] The invention relates to a detection tool, in particular to indoor formaldehyde detection equipment. Background technique [0002] With the development of society, many people have higher and higher requirements for interior decoration, but many existing furniture have excessive formaldehyde. The impact of formaldehyde on human health is mainly manifested in abnormal sense of smell, irritation, allergies, abnormal lung function, In terms of immune function abnormalities, high concentrations can cause nausea, vomiting, coughing, chest tightness, asthma and even emphysema. Long-term low-concentration exposure to formaldehyde gas can cause headaches, dizziness, fatigue, bilateral asymmetrical sensory disturbances, excessive perspiration, and visual impairment, and can inhibit sweat gland secretion, leading to dry and chapped skin. , Eyes and skin are highly irritating and toxic to the nervous system, immune system, liver, etc. Therefore, the detection of...
