Embodiment Construction

[0009] See attached picture. The present invention comprises a hollow glass sphere 2, a hollow conduit 7 is arranged below the hollow glass sphere 2, one end of the hollow conduit 7 is arranged in the hollow glass sphere 2, and the other end is connected with the air outlet 13 of a miniature air pump 12, and the miniature The air inlet 14 of the air pump 12 is connected with the smoking device 20 , the smoking device 20 is connected with the control circuit 21 , and the control circuit 21 is connected with the carbon dioxide sensor 16 .

[0010] The control circuit 21 includes a rectification circuit and a logic circuit. The rectification circuit can convert the 220v commercial power into a low-voltage direct current to supply power to the logic circuit. After the logic circuit detects that the carbon dioxide content in the air exceeds a preset value through the carbon dioxide sensor 16, Control the micro-air pump 12 to pump air to the smoking device 20 and pump the smoke gene...

Abstract

The invention provides an air quality detection ball. The detection ball comprises hollow glass balls, wherein the lower parts of the hollow glass balls are provided with hollow conduits; one ends of the hollow conduits are arranged in the hollow glass balls, and the other ends of the hollow conduits are connected with an air outlet of a micro air pump; an air inlet of the micro air pump is connected with a fuming device; the fuming device is connected with a control circuit; and the control circuit is connected with a carbon dioxide sensor. By the air quality detection ball, during use, when the content of carbon dioxide is extremely high, the control circuit controls the fuming device to generate smoke, the content of the carbon dioxide in the current air is reflected through transparent and turbid intuitive visual effects in the hollow glass balls, and the air quality is detected through the transparent and turbid effects, so that people can conveniently understand the principle, transmission of the information on the content of the carbon dioxide is facilitated, and the aims of reminding and helping a user to own a healthy and comfortable living environment are fulfilled.

Description

technical field [0001] The invention relates to an air quality detection and alarm device. Background technique [0002] Although there are already formed air quality detection products on the market, they are often not aimed at individuals or families, and their practicability is not very strong. Individuals or household users may not need to know the specific air quality data, even if there is data, they may not understand it, but they need to know whether the current air quality is suitable for human needs and whether it will be harmful to health. Contents of the invention [0003] The invention provides an air quality detection ball which can intuitively reflect the carbon dioxide content in the current air, remind and help users to have a healthy and comfortable living environment. [0004] For this reason, the present invention adopts following technical scheme: [0005] The detection ball comprises a hollow glass sphere, and a hollow conduit is arranged below th...
