Embodiment 1

[0051] Such as figure 2 As shown, the shading and reflecting member 1 of this embodiment is also provided with an infrared sensor 21 for gesture sensing. When used for different gestures, the display screen will display different values ​​accordingly. The lead wire 24 will go out through the PCB lamp board 3 and connect to the display screen.

Embodiment 2

[0053] Such as figure 1 As shown, in the display device of this embodiment, the light-shielding and reflecting member 1 is provided with a display portion 12, and the display portion 12 is arranged in the upper area of ​​the installation chamber in the middle of the light guide ring 23;

[0054] In this embodiment, the display unit 12 is arranged on the corresponding top of the display screen 22, so that the visible information sent by the display screen 22 is illuminated through the transparent display unit 12 to be directly observed by the user; at the same time, the display unit The outer circumference of 12 is provided with the same shape corresponding to the outer contour of the display screen 22, so as to facilitate checking the numerical value above the display screen. In this embodiment, the shape of the display screen 22 and the display part 12 are both rectangular, but not limited to rectangular, but also square, circular or regular shapes.

Embodiment 3

[0056] Such as Figure 5 As shown, in this embodiment, the PCB light strip is installed on the inner side 5 of the light transmission circle, and the PCB light strip includes a plurality of light points 4 fixedly installed on the PCB light board 3, and each light point 4 is arranged at equal intervals A circular line concentric with the light-transmitting ring 11, and each light point 4 is set in the installation chamber between the light-guiding ring 23 and the refracting member 2, so that the light emitted by the PCB light strip is only in the installation cavity outside the light-guiding ring 23 In the room, it is emitted through the light-transmitting ring 11; at the same time, the visible light emitted by the PCB light strip is prevented from irradiating the display screen, which will affect the imaging effect of the display screen. In addition, the illumination direction of each lamp point 4 is parallel to the PCB lamp panel 3 and toward the light-transmitting ring 11 , ...

Abstract

The invention provides a display device of indoor air environment monitoring equipment.The display device comprises a display screen and further comprises a disc-shaped hollow installation cavity.The hollow installation cavity is composed of a shading and reflecting part, a refraction part and a PCB lamp panel part.An annular PCB lamp belt capable of emitting variable light is arranged in the installation cavity.The display screen is arranged in the middle of the PCB lamp belt.The display device is convenient to use, reliable, capable of monitoring indoor air quality condition and uniform in LED lamp light reflection.The invention further provides an indicating method.By means of the indicating method, the indoor air quality can be monitored in real time on the online or offline condition.

Description

technical field [0001] The invention belongs to the technical field of air quality detection devices, and in particular relates to a display device and an indication method of indoor air environment monitoring equipment. Background technique [0002] With the development of society, the problem of environmental pollution is becoming more and more serious, and the quality of the environment is directly related to people's physical and mental health. In order to enable people to clearly know the environmental quality in the indoor air, more and more real-time The air detection for detecting air quality can detect the composition of various pollutants in the air, so that people can know the surrounding air quality in a timely manner. [0003] Publication number CN204215674U discloses an LED display control assembly and an air detector. The above-mentioned LED display control assembly includes a main PCB board and an LED lamp board electrically connected to the main PCB board. T...
