Device for removing working contaminants of cash-counting machine and office equipment

Abstract

The invention discloses a device for removing working contaminants of a cash-counting machine and office equipment, belongs to the field of dust removal by ventilation and mainly aims to solve the problem of contamination caused by the office equipment to the environment. The device comprises fans, a ventilation pipeline, box-type covers, valves and controllers, wherein the box-type covers includea cover of the cash-counting machine, a cover of a printer and a cover of a duplicator; the quantity of the box-type covers is greater than or equal to 1; each box-type cover is composed of a cover body and an air outlet, and sealing rubber strips are arranged at the positions, making contact with a working table, of bottom edges of the cover bodies; the position of an operation port on each cover body corresponds to an operation position of covered equipment; a sensor is arranged nearby the operation port on each cover body, the sensors are electrically connected with the controllers, the controllers are electrically connected with fans and valve drivers, and delay modules are electrically connected with the controllers; and the air outlets of the box-type covers are connected with an outdoor exhaust port through the fans, the valves and a dust removal device. The device has the advantages of being convenient to use and thorough in contaminant discharge and can be widely applied to office places of banks, organs, enterprises and institutions.

Description

technical field [0001] The invention belongs to the field of ventilation and dust removal, and mainly relates to a device for removing working pollutants from banknote counters and office equipment to ensure the health of workers. Background technique [0002] Existing banknote counters are generally only provided with a small dust collection box on the upper part of the banknote counter, and there is a small fan and filter inside to filter and remove dust. The filtered gas is discharged on the banknote counter, and the polluted gas still stays in the indoor. And it can only filter relatively large particles and dust, but a large amount of tiny dust and bacteria and viruses generated by the banknote counter cannot be filtered out at all. Even if a sterilizing and fine-filtering device is installed, 100% sterilizing and filtering cannot be achieved according to the existing technology, and it still pervades in a small and sealed working space. In banks, hospitals, financial...

Problems solved by technology

[0002] Existing banknote counters generally only have a small dust collection box on the top of the banknote counter, with a small fan and filter inside to filter and remove dust. The filtered gas is discharged on the banknote counter, and the polluted gas still stays in the indoor

And it can only filter relatively large particles and dust, while a large amount of tiny dust and bacteria and viruses generated by the banknote counter cannot be filtered out at all.

Even if a sterilizing and fine-filtering device is installed, 100% sterilizing and filtering cannot be achieved according to the existing technology, and the air is still pervasive in a small and sealed working space.
