Cleaning type code scanner with anti-falling function

Abstract

The invention relates to a cleaning type code scanner with an anti-falling function comprising a body and a handle. The handle is mounted on the body. The scanner further comprises two buffer mechanisms and two dust removal mechanisms. Each dust removal mechanism comprises an air conveying pipe, a supporting pipe, an air inlet pipe, a dustproof assembly, two air suction cylinders, two piston blocks, two connecting rods and at least two air blowing pipes. Each buffering mechanism comprises a sliding rod, two transmission rods, two sliding sleeves and two springs. A dustproof assembly comprisesa first permanent magnet, a second permanent magnet and a filter screen. Through the supporting and buffering effects of the buffering mechanism, the probability that a code scanning window of the code scanner collides with a table top is reduced, the probability that a code scanning gun is damaged is reduced, dust on the code scanning window of the code scanner can be blown off through the dust removal mechanism, the number of the dust on the code scanning window is reduced, and the code scanning precision of the code scanner is improved.

Description

Technical field [0001] The invention relates to the field of code scanning equipment, in particular to a clean code scanner with anti-drop function. Background technique [0002] The scanner is a machine that reads barcode information. The infrared light source is emitted, and then the chip is used to decode according to the reflected result, and finally the correct character represented by the bar code is returned. [0003] In the process of picking and placing the code scanner of the prior art, the code scanning window of the code scanner is likely to collide with the desktop, causing the code scanner to be easily damaged. Not only that, the code scanning window of the code scanner of the prior art Dust is easy to accumulate, and under the cover of dust, it will affect the scanning accuracy of the code scanner and reduce the practicability of the code scanner. Summary of the invention [0004] The technical problem to be solved by the present invention is to provide a clean code...
