Embodiment Construction
[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0033] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.
[0034] In addition, if there are descriptions involving "first", "second" and ...

The invention discloses an air detection device. The air detection device comprises a detection main body and a framework, wherein the detection main body comprises a shell body and a sensor which is mounted in the shell body and is used for detecting air quality; the shell body is provided with an air inlet region; the air inlet region is provided with an air inlet hole through which external air enters the shell body, and then the external air is detected by the sensor; the shell body has a spherical shape; the framework sleeves the periphery of the detection main body; the detection main body is rotatably mounted in the framework. According to the air detection device disclosed by the invention, on one hand, the detection main body is in rotary connection with the framework so that the detection main body is in contact with the air in an active manner and the responding time of the detection main body is greatly shortened; on the other hand, the shell of the detection main body has the spherical shape so that the rotary speed is more uniform when the detection main body rotates, the contact speed between the external air and the sensor is more stable and detection errors are smaller.
Description
technical field [0001] The invention relates to the technical field of air detection, in particular to an air detection device. Background technique [0002] In the existing air detection device, an air intake hole is provided on the casing of the detection body, and external air can enter the detection body through the air intake hole, so that it can be detected by the built-in sensor in the detection body. [0003] In this detection method, the external gas can only passively diffuse into the detection body, and the built-in sensor cannot actively contact the external air, resulting in a long detection response time of the built-in sensor. Contents of the invention [0004] The main purpose of the present invention is to propose an air detection device aimed at reducing the response time for air quality detection. [0005] In order to achieve the above object, the air detection device proposed by the present invention includes: [0006] The detection body includes a ho...
