Auxiliary dust removal device for instruments

Abstract

The invention relates to the technical field of instruments, and discloses an auxiliary dust removal device for instruments. The device comprises a shell, a rotating shaft I is movably connected in the shell, a rotating rod I is fixedly connected outside the rotating shaft I, a connecting rod I is movably connected to one end, far away from the rotating shaft I, of the rotating rod I, one end, far away from the rotating rod I, of the connecting rod I is movably connected with a connecting rod II, a short rod is movably connected to the outside of the connecting rod II, a sliding rod is movably connected to the end, away from the connecting rod II, of the short rod, a fixing plate is fixedly connected to the outside of the sliding rod, a rotating shaft II is movably connected to the inside of the fixing plate, and a rotating rod II is fixedly connected to the outside of the rotating shaft II. Through interaction of the fixing plate, the rotating shaft II, the rotating rod II, a swing rod, a sliding block, a detection assembly I and a detection assembly II, dust deposited on the surface of an anode can be cleaned, so that the anode is kept clean, and the situation that dust deposition affects an electrostatic field, and affects the dust removal of an instrument is is avoided.

Description

technical field [0001] The invention relates to the technical field of instruments, in particular to an auxiliary dust removal device for instruments. Background technique [0002] Instrument refers to the collective name of instruments for measuring temperature, air pressure, electricity, blood pressure, flow, etc. It looks like a timekeeping watch and can directly display the value from the scale. [0003] During the long-term use of the instrument, a large amount of dust will adhere to its surface, and most of the instruments are small in size and relatively compact in internal structure. When working, the ventilation holes set on the side are used for ventilation, so that the external air can directly enter the casing. However, when the air enters, it also brings the external dust to the inside of the shell. As time goes by, the dust inside the shell will accumulate more and more. The accumulation of a large amount of dust will not only affect the heat dissipation, but a...
