Technical Field

[0001] The utility model belongs to the technical field of safety engineering, and in particular relates to an air detection device for safety engineering. Background Art

[0002] Safety Engineering is a secondary discipline under the first-level discipline "Safety Science and Engineering". This major focuses on cultivating compound senior engineering and technical talents who can engage in safety technology and engineering, safety science and research, safety supervision and management, identification and detection of dangerous and harmful factors in the workplace, safety design and production, safety education and training, and occupational health protection in production enterprises. It is a comprehensive interdisciplinary subject with a very wide range of coverage.

[0003] Air purification refers to providing overall solutions such as sterilization and disinfection, dust reduction and haze removal, removal of harmful decoration residues and odors for various indoor environmental problems, improving living and office conditions, and promoting physical and mental health. Indoor environmental pollutants and pollution sources mainly include radioactive gases, mold, particulate matter, decoration residues, secondhand smoke, etc. With the improvement of people's living standards, people's requirements for indoor environment and air quality are also getting higher and higher. After decoration, public places such as supermarkets and shopping malls need to test their air quality to ensure their normal business.

[0004] Newly renovated places need to be ventilated for a period of time before they are conducive to people's use. In order to ensure that the air quality in the place meets the standard, it is necessary to use air detection devices for testing. When the gases in the air that are harmful to the human body meet the standard, the place can be opened for use. Currently, most of the air detection devices used are handheld devices. When testing, the staff needs to enter the place for testing, which is inefficient and may affect the health of the staff. At the same time, the usage method is too single and does not make good use of the detection work. Utility Model Content
