Gas sensor dust prevention and removal device

Abstract

The invention discloses a gas sensor dust prevention and removal device which comprises a shell. A mounting groove with an upward opening is arranged in the shell, a gas sensor is fixedly connected tothe lower inner wall of the mounting groove, a blower is arranged on one side wall of the shell, the output end of the blower is connected with a main pipeline, multiple branched pipelines are arrayed horizontally on the lower inner wall of the mounting groove, the main pipeline is communicated with the branched pipelines, a dust screen is arranged in the position of the opening of the mounting groove, and a groove meshed with the dust screen is arranged in the inner wall of the mounting groove. By the arrangement of the dust screen, larger particles in the air are blocked out, outside air isdrawn by the blower, the main pipeline and the branched pipelines blow air to the inside of the mounting groove, fine dust in the mounting groove is blown out of the mounting groove, dust caught on the dust screen is blown off, dust prevention and removal are carried out for the device, and service life of the device is prolonged.

Description

technical field [0001] The invention relates to the technical field of gas sensors, in particular to a dust-proof and dust-removing device for a gas sensor. Background technique [0002] A gas sensor is a converter that converts a certain gas volume fraction into a corresponding electrical signal. The probe uses the gas sensor to condition the gas sample, usually including filtering out impurities and interfering gases, drying or cooling the display part of the instrument. The general gas sensor is exposed to the outside, and the dust in the air will enter the sensor, corrode its internal parts, and reduce the service life of the device; therefore, we propose a gas sensor dust-proof and dust-removing device to solve the above problems. Contents of the invention [0003] The purpose of the present invention is to solve the problems in the prior art that the general gas sensor is exposed to the outside, and the dust in the air will enter the sensor, corrode its internal part...
