Description

Technical Field

[0001] The utility model relates to the technical field of constant temperature and humidity test chambers, and specifically relates to an air duct cleaning device for a constant temperature and humidity test chamber. Background Technique

[0002] A test chamber is the general term for products in the environmental testing industry, which simulates the natural climate environment within an effective space range. The test types include: high and low temperature test chambers, xenon lamp aging test chambers, ultraviolet aging test chambers, box-type rain test chambers, rust preventive oils, drip devices, purification and clean storage cabinets, nitrogen storage cabinets, non-standard products, etc.

[0003] As disclosed in a duct cleaning device for a special constant temperature and humidity test chamber for automotive parts with the authorization announcement number CN215940933U, which specifically relates to the field of constant temperature and humidity test chambers, including a U-shaped plate. A cleaning mechanism is arranged on one side of the U-shaped plate. The cleaning mechanism includes a lifting plate. Two threaded holes are symmetrically opened on the lifting plate. Threaded rods are arranged in the inner cavities of the two threaded holes. Vertical plates are symmetrically and fixedly connected to the lifting plate. A round rod is arranged between the two vertical plates. A plurality of brushes are installed on the round rod. One end of the round rod is movably connected to one of the vertical plates, and the other end of the round rod penetrates through the other vertical plate and is fixedly connected to a first motor. By setting the cleaning mechanism, the first motor drives the round rod and the brushes to rotate, thereby cleaning the dust on the air duct. The dust collector collects the dust through a suction pipe. The second motor drives the sheave and the threaded rod to rotate, thereby driving the lifting plate to lift, and the dust on the air duct can be cleaned. However, the cleaning measures of this utility model are not convenient for the comprehensive cleaning of the inner wall of the air duct, and lack a filtering measure, which is not convenient for ensuring the thorough cleaning effect of the air duct. Therefore, we propose an air duct cleaning device for a constant temperature and humidity test chamber, which solves the problems of incomplete cleaning and filtering of this utility model, and improves the practical effect and use convenience of this utility model.
