Description

Technical Field

[0001] The utility model relates to the technical field of air detection, in particular to a public toilet air sensor with multi-directional air intake. Background Technique

[0002] Air quality detection refers to the detection of the quality of air. The quality of air reflects the concentration of pollutants in the air. Air pollution is a complex phenomenon, and the concentration of air pollutants at a specific time and place is affected by many factors. The size of anthropogenic pollutant emissions from fixed and mobile pollution sources is one of the most important factors affecting air quality. As one of the places with dense population flow, the environmental hygiene and air quality inside public toilets are related to people's health. Therefore, it is necessary to detect the air quality inside public toilets so that people entering the public toilets can understand the air quality status inside in real time and feel at ease when using the toilets.

[0003] When the current public toilet air sensor detects the air quality inside the public toilet, it only takes air samples through a single sampling port, and the sampling range is small, resulting in low accuracy of the air quality detection results. Content of the Utility Model

[0018] Please refer to Figures 1-3 , the present utility model provides a technical solution: a multi-directional air intake public toilet air sensor, including a main body 1, an air intake base 2, and a mounting top plate 3. The main body 1 is in an overall cylindrical structure. The mounting top plate 3 is fixedly arranged on the upper part of the main body 1, and several groups of fixing plates 31 are arranged on the side of the mounting top plate 3. The air intake base 2 is arranged at the lower part of the main body 1, and several groups of air intake cylinders 23 are arranged on the side of the air intake base 2. An annular upper clamping seat 11 is arranged at the lower part of the main body 1, and an annular lower clamping seat 21 is arranged at the upper part of the air intake base 2. The upper clamping seat 11 and the lower clamping seat 21 are clamped with each other. A central position on the upper surface of the air intake base 2 is provided with an air inlet pipe 25, and an air inlet 15 connected to the air inlet pipe 25 is arranged at the lower part of the main body 1. A sensor body is arranged inside the main body 1, and an exhaust port 13 is arranged on the side of the top of the main body 1.

[0019] Furthermore, an annular clamping edge 22 is arranged inside the lower clamping seat 21, and an annular clamping groove 12 is arranged outside the upper clamping seat 11. The clamping edge 22 is fitted and clamped in the clamping groove 12. And a plurality of groups of balls 17 are uniformly embedded in the lower side wall of the clamping groove 12.

[0020] Furthermore, the air intake cylinders 23 are uniformly arranged around the side of the air intake base 2 and are communicated with the air inlet pipe 25.
