Description

Circulating gas purification device, printer and text, line, drawing device

technical field

The utility model relates to a gas purification device for a printer, in particular to a circulation type gas purification device and a printer with the purification device and a device for drawing characters, lines and drawings.

Background technique

Preventing printers from harming human health At present, printing technology is more and more widely used in various fields of people's work, study and life, and people have more and more opportunities to come into contact with printers and printed products, but their impact on human health has not yet been caused. enough attention.

According to foreign research reports, printers have the following three impacts on human health: (1) Carbon printers are the most widely used at present, and the developer powder used in it has two types: dry and wet. The dry developer powder is made of super carbon black, and the aromatic hydrocarbons in it are carcinogenic. Wet developing powder is to disperse carbon black in hydrocarbon solvent, and aliphatic hydrocarbons containing 10 to 20 carbon atoms contribute to the growth of tumors. Since the hydrocarbons used have low boiling point and are volatile, poor ventilation will cause harm to long-term contacts. (2) The developing materials of carbon-free printers are very irritating and can cause diseases in the skin, eyes, respiratory tract and nervous system. In addition, carbonless printing can also release some substances that may cause cancer during the printing process. (3) When the printer is working, there is a certain amount of ozone in the copying room due to static electricity. These ozone is produced by the chemical reaction between the high-voltage parts in the printer and the air. Ozone has a high oxidation effect and can convert nitrogen into nitrogen oxides, which is highly irritating to the human respiratory tract. Ozone has a large specificity, slow flow, and poor ventilation due to dust prevention in the room, which can easily lead to "copier syndrome" for printer operators. The main symptoms are dry mouth and throat, chest tightness, cough, dizziness, headache, vision loss, etc. In severe cases, toxic edema may occur, and it may also cause symptoms of the nervous system.
