Ozone dilution cyclone dust removal device of printer

Abstract

The invention relates to an ozone dilution cyclone dust removal device of a printer, and belongs to the field of dust removal equipment of office printers. The ozone dilution cyclone dust removal device comprises a hollow conical dust remover body, wherein a relatively large diameter end of the dust remover body is a bottom end, and a waste gas inlet used for sucking waste gas of the printer and an air inlet used for sucking air are formed in the bottom end of the dust remover body; the waste gas inlet and the air inlet are both arranged in the tangential direction of the dust remover body; the air outlet pipe, communicated with the interior of the dust collector body, is arranged at the bottom end of the dust collector body; the air outlet pipe is arranged in the axial direction of the dust remover body; an air outlet is formed in one end, located in the dust remover body, of the air outlet pipe; the distance between the air outlet and the bottom end of the dust remover body is a first distance; and the distance between the waste gas inlet and the bottom end of the dust remover body is a second distance, wherein the second distance is larger than the first distance. According to the device, the air and the ozone are fully mixed, the dust is removed, the ozone concentration is reduced, and the ozone generated by the printer is fully utilized.

Description

technical field [0001] The invention belongs to the field of dust removal equipment for office printers, and relates to an ozone dilution cyclone dust removal device for printers. Background technique [0002] Laser printers have the advantages of fast printing speed and low printing cost. However, when laser printers are working, they will produce ozone and inhalable dust such as toner and paper particles. Ozone has strong oxidizing properties. When the air contains a low concentration of ozone It has beneficial effects such as fresh air, but when the concentration of ozone in the air exceeds the tolerance range of the human body, it will stimulate the human body and have adverse effects on the human body.

Problems solved by technology

[0002] Laser printers have the advantages of fast printing speed and low printing cost. However, when laser printers are working, they will produce ozone and inhalable dust such as toner and paper particles. Ozone has strong oxidizing properties. When the air contains a low concentration of ozone It has beneficial effects such as fresh air, but when the concentration of ozone in the air exceeds the tolerance range of the human body, it will stimulate the human body and have adverse effects on the human body.

[0003] Because printers are usually installed in small and relatively closed environments such as offices, limited by the office environment, printers are usually installed near employees' seats. After the printer works for a long time, due to the low air flow in the office, ozone and toner can be inhaled. Dust will accumulate locally indoors, exceeding the acceptable concentration of the human body, and office workers are in the indoor environment for a long time, and the ozone, toner, paper dust particles and other inhalable dust generated by laser printers will inevitably cause harm to office workers

[0004] The traditional treatment method usually sets a dust filter and an ozone filter at the same time to filter and eliminate the dust and ozone generated by the printer, but the dust filter needs to be replaced regularly, otherwise the dust will block the filter after the dust filter has been working for a long time. eye, resulting in the reduction or even failure of the filtering effect of the filter, while the ozone filter decomposes ozone into ordinary oxygen, failing to effectively use the beneficial effect of low ozone concentration
