Description

Air detector Technical Field The utility model relates to the field of air detection, in particular to an air detector. Background Under the current state of air environment pollution and the rapid development of the health industry, people pay more attention to the air pollution index. Particularly in the decoration scene, the indoor air pollution problem is particularly remarkable, and harmful substances such as formaldehyde, benzene series, VOCs (volatile organic compounds) and the like are released in a large amount in the decoration material, so that the long-term exposure can cause serious harm to human health. The concentration of the pollutants can be monitored in real time by using the air detector, and an important basis is provided for the safety of living environment. An air detector in the prior art is provided with an air inlet for directly introducing air, turbulent flow is easy to form in a pipeline by air flow, air is unevenly mixed, and the concentration difference of samples collected by a sensor at different time points is large and the data stability is poor. New solutions are therefore required to address this problem. Disclosure of utility model Aiming at the defects existing in the prior art, the utility model aims to provide an air detector which realizes high-precision detection by stabilizing air flow through a spiral air inlet pipe. The technical aim of the utility model is achieved through the following technical scheme that the air detector comprises a main body, a detection sensor and an air pump, wherein the top end of the main body is provided with an air inlet pipe, one end of the air inlet pipe, which is far away from the main body, is provided with a spiral air inlet pipe, the air inlet pipe is provided with an air inlet cover, the air inlet cover is hollow and contains the spiral air inlet pipe, and a plurality of air ports are formed in the air inlet cover in the circumferential direction. The air inlet cover comprises an upper cover and a lower cover which are detachably combined, the lower cover is penetrated by the air inlet pipe and fixedly connected, a filter screen ring groove is formed in the inner bottom surface of the lower cover, and a coarse filter screen is detachably connected in the filter screen ring groove. The utility model is further characterized in that the lower cover is provided with a first magnet, the upper cover is provided with a second magnet matched with the first magnet, and the upper cover and the lower cover can be separated and combined through the first magnet and the second magnet. The utility model is further characterized in that the main body is provided with a display screen for displaying the concentration values of various pollutants in the air. In summary, the utility model has the following beneficial effects: According to the utility model, the spiral air inlet pipe is arranged, so that the air flow path can be prolonged, the air flow is more stable, and the detection precision of the detection sensor is improved.
