Air quality detecting system capable of automatically replacing filter cartridges

Abstract

The invention discloses an air quality detecting system capable of automatically replacing filter cartridges. The air quality detecting system comprises a detection assembly, wherein the detection assembly comprises a sensor, a processor and a device shell; an air inlet and an air outlet are formed in the device shell; a detection channel is formed between the air inlet and the air outlet; the sensor is arranged in the detection channel; a filter cartridge assembly is arranged at the air inlet; the filter cartridge assembly comprises filter cartridges, a first roller, a second roller and a driving device; a starter is arranged on the driving device and connected to the processor through signals; all the filter cartridges are connected with the first roller and the second roller and wound on the first roller and the second roller; the filter cartridges cover the air inlet. The air quality detecting system has the advantages of operating under outdoor environment, automatically and periodically replacing invalid filtering material in a certain period, guaranteeing the effectiveness of detection data, manually adjusting periodic time according to the difference of contents of air pollutants under different environments, and simply and conveniently maintaining and replacing the novel filtering material.

Description

technical field [0001] The invention relates to the technical field of air detection equipment, and more specifically relates to an air quality detection system capable of automatically replacing filter elements. Background technique [0002] At present, the outdoor particle detection devices with a typical structure in the prior art are only equipped with a single filter. If it is in an outdoor environment and the haze weather is severe, the single filter will cause the filter to fail in a short time. If it is not replaced in time, it will cause large errors in the detection data and bring inconvenience to the atmospheric environment detection work. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an air quality detection system that can automatically replace the filter element to solve the above technical problems. [0004] For this reason, the present invention provides the following technical solutions. [0...
