Description

Technical Field

[0001] The utility model relates to the technical field of dust detection, and more specifically, it relates to a light-transmitting device that is easy to disassemble. Background Art

[0002] The light scattering method is a commonly used dust concentration detection technology. Its basic principle is to measure the dust concentration by using the light scattering characteristics of dust particles in the air. Due to its high precision, high stability and convenient operation, the light scattering method for dust detection has been widely used in the field of dust concentration monitoring.

[0003] At present, the light scattering method plays an important role in the field of dust detection. When the light emitted by the light source passes through the dusty air, the dust particles will cause the light to scatter. By measuring the intensity of the scattered light, the particle size and concentration of the dust can be inferred.

[0004] However, when detecting the dust concentration by the light scattering method, if the optical path is not accurately calibrated, the laser may not accurately irradiate the detection area, or the irradiation angle is deviated, resulting in measurement errors of the scattered light. For this reason, a light-transmitting device that is easy to disassemble is proposed to improve the existing problems. Summary of the Utility Model

At the same time, the fitting of the positioning pin and the fitting groove also facilitates the disassembly and installation of the adapter housing and the fitting housing, providing convenience for the installation and disassembly of the light-transmitting device.

[0014] The present utility model is further configured such that: the tail assembly includes a tail main body, a first thread is provided around the side wall of the tail main body, and a second thread is provided around the side wall of the tail main body away from the first thread.

[0015] The present utility model is further configured such that: the tail main body is in the shape of a cylinder, a light outlet hole is provided through the center of the tail main body, and the light outlet hole is in communication with the fitting assembly.
