Mobile POS machine with dust removal function based on block chain technology

Abstract

The invention relates to a mobile POS machine with a dust removal function based on a block chain technology. The machine comprises a main body, a display screen, a card slot and at least two controlkeys, a dust removal mechanism is also arranged in the main body; the dust removal mechanism comprises a baffle, two limiting grooves, two limiting blocks, two springs and two air blowing assemblies.The air blowing assembly comprises a sealing cylinder, a piston block, a connecting pipe, a through hole, a bypass pipe and a one-way valve. A cleaning mechanism is arranged on the main body, the cleaning mechanism comprises a driving assembly, a rotating pipe, an air outlet notch, two mounting bearings and two hoses. In the mobile POS machine with the dust removal function based on the block chain technology, data storage is carried out by adopting a block chain technology, so that the data security degree is high, dust in the card slot can be removed through the dust removal mechanism, the probability of poor contact of the POS machine is reduced, the stability of the POS machine is improved, dust on the display screen can be removed through the cleaning mechanism, and the display definition of the display screen is improved.

Description

technical field [0001] The invention relates to a mobile POS machine with dust removal function based on block chain technology. Background technique [0002] Blockchain technology uses block chain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and utilizes intelligence composed of automated script codes. A new distributed infrastructure and computing method that uses contracts to program and manipulate data. It is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms. [0003] Blockchain technology has a high degree of data security and is widely used, including the field of mobile payment equipment application technology. [0004] The mobile POS machines of the prior art generally adopt traditional data encryption methods, which ar...

Problems solved by technology

[0004] The mobile POS machines of the prior art generally adopt traditional data encryption methods, which are easy to cause data loss, and after the mobile POS machines of the prior art have been used for a long time, a large amount of dust will accumulate on the display screen of the POS machine. Under the cover of dust, the clarity of the display screen is reduced, and the practicability of the POS machine is reduced. Not only that, when the POS machine of the prior art is inserting and pulling out the card, the card is easy to bring dust and impurities into the card slot The interior of the POS machine leads to poor contact and increases the failure rate of the POS machine
