Description

Technical Field

[0001] The utility model relates to the technical field of numerical control, in particular to a digital control instrument. Background Art

[0002] An instrument that converts measurements into digital quantities and displays them in digital form. In industrial measurements, analog quantities such as displacement, current, voltage, and air pressure are converted into digital quantities (abbreviated as analog-to-digital conversion) through an analog-to-digital converter. Traditional control instruments often require manual assistance for adjustment and control, which leads to a high reliance on manual assistance, which is not conducive to industrial development.

[0003] For example, the publication number CN201920390771.4 discloses the "Digital Control Instrument", which adds a processor 20 for data processing in the digital control instrument, making the digital control instrument more intelligent and automated than the traditional control instrument, thus avoiding the control instrument's high reliance on manual assistance.

[0004] However, for digital instruments, because the internal heat is high due to long-term operation, the heat will be discharged through the heat dissipation holes. However, at this stage, the dust isolation treatment effect of the heat dissipation holes of digital instruments is relatively simple. Therefore, when dust enters the heat dissipation holes and accumulates too much, it is not conducive to the use of digital instruments. Utility Model Content
