Description

空气质量检测装置及其应用Air quality detection device and its application 技术领域Technical field
本发明涉及到空气质量检测领域，尤其涉及到一空气质量检测装置及其应用。The invention relates to the field of air quality detection, in particular to an air quality detection device and its application.
背景技术Background technique
空气质量检测器是用于检测空气质量的装置。当前随着雾霾天气出现的频率的增多，人们逐渐意识到了空气质量对于身体健康的重要性，尤其是对于抵抗力减弱的老年人和儿童而言，在空气质量较差的情况下，最好是待在室内活动，减少室外活动的频率。由于个人活动空间的差异性，为了获得差异化的空气质量数据，人们通常自行选择购买空气质量检测器来检测活动空间内的空气质量。An air quality detector is a device for detecting air quality. With the increasing frequency of haze weather, people have gradually realized the importance of air quality for physical health, especially for the elderly and children with weakened resistance. In the case of poor air quality, it is best to It is to stay indoors and reduce the frequency of outdoor activities. Due to the difference in personal activity space, in order to obtain differentiated air quality data, people usually choose to purchase an air quality detector to detect the air quality in the activity space.
空气质量检测器是一类可实时检测空气质量的仪器，一般是基于激光检测原理，当粉尘通过所述空气质量检测器内的光学传感器的光敏区时，颗粒会散射入射的激光，通过探测反射光并将其转换成电信号，经过后续的电路处理得到和粉尘颗粒散射光强相关的电压信号，然后通过对于电压信号的数据处理和计算，就可以得出空气中颗粒的质量浓度数值。An air quality detector is a type of instrument that can detect air quality in real time. Generally, it is based on the principle of laser detection. When dust passes through the photosensitive area of the optical sensor in the air quality detector, particles will scatter the incident laser light. The light is converted into an electrical signal, and a voltage signal related to the intensity of light scattered by the dust particles is obtained through subsequent circuit processing. Then, the data of the voltage signal is processed and calculated to obtain the mass concentration value of the particles in the air.
目前对于电子设备存着着追求轻薄化的趋势，用户希望电子设备的体积能够越来越小，一方面能够减少占地面积，另一方面也使得电子设备本身的携带和使用更加的方便，尤其是对于空气质量检测器而言，用户往往希望能够通过空气质量检测器时刻获得周围环境的空气质量数据。而一旦所述空气质量检测器的体积过大，用户根本就不会愿意携带该种空气质量检测器外出。与之相矛盾的是，目前市场上的激光空气检测器出于成本的考虑，因为电子设备的小型化需要一定的研发投入，一般空气检测器的体积越大，检测精度也越大，而体积较小时，检测精度也相应较低，难以满足目前各种场合对于空气检测器的需求。At present, there is a trend of pursuing thinness and thinness of electronic equipment. Users hope that the volume of electronic equipment can be smaller and smaller, on the one hand, it can reduce the footprint, on the other hand, it makes the electronic equipment itself more convenient to carry and use, especially For the air quality detector, users often want to be able to obtain the air quality data of the surrounding environment through the air quality detector at all times. Once the volume of the air quality detector is too large, the user will not be willing to carry the air quality detector out. In contradiction, the current laser air detectors on the market are for cost reasons, because the miniaturization of electronic equipment requires a certain investment in research and development. Generally, the larger the volume of the air detector, the greater the detection accuracy, and the larger When smaller, the detection accuracy is correspondingly lower, and it is difficult to meet the current requirements for air detectors in various occasions.
空气质量和人们的生活健康息息相关，随着经济的发展以及在经济发展初期伴随的日益加剧的污染，人们越来越重视周围活动区域中的空气质量。Air quality is closely related to people's life and health. With the development of the economy and the increasing pollution accompanying in the early stage of economic development, people pay more and more attention to the air quality in the surrounding active areas.
空气质量检测器是一类用于实时检测空气质量的仪器。影响到空气质量的关键在于空气质量中的颗粒物含量，比如说目前被热切关注的PM2.5就是指大气 中直径小于或者等于2.5微米的颗粒物，因为体积质量较小，从而能够携带较多的有害物质进入到人体中，对于健康造成严重的威胁。Air quality detectors are a class of instruments used to detect air quality in real time. The key to affecting air quality is the content of particulate matter in the air quality. For example, PM2.5, which is currently being eagerly concerned, refers to particulate matter with a diameter of 2.5 microns or less in the atmosphere. Because of its small volume, it can carry more harmful substances. The entry of substances into the human body poses a serious threat to health.
空气检测器的工作原理一般是基于激光检测原理，当粉尘通过光学传感器的光敏区时，颗粒会散射入射的激光，通过探测反射光并将其转换成电信号，经过后续的电路处理后得到和粉尘颗粒散射光强相关的电压信号，然后通过对于电压信号的数据处理和计算，就可以得出颗粒的质量浓度数值。The working principle of the air detector is generally based on the principle of laser detection. When the dust passes through the photosensitive area of the optical sensor, the particles will scatter the incident laser light, detect the reflected light and convert it into an electrical signal. The dust particles scatter the light intensity-related voltage signal, and then through the data processing and calculation of the voltage signal, the mass concentration value of the particles can be obtained.
目前的空气检测器一般具有较大的体积，以保证有较高的检测精度，尤其是对于一些科研企业来说，这样的大型设备结构复杂，精度很高，有利于后续的科学研究。由于其庞大的体积和高昂的费用这一类设备难以被普及到日常生活中应用。The current air detectors generally have a large volume to ensure high detection accuracy. Especially for some scientific research enterprises, such large equipment has a complicated structure and high accuracy, which is conducive to subsequent scientific research. Due to its large size and high cost, this type of equipment is difficult to be popularized in daily life applications.

Further, the first air duct 31 and the second air duct 32 have a turn of more than 90 degrees in the height direction. That is, the air turns around the circuit board unit 22 by more than 90 degrees. The turning design of the air duct 30 enables the air quality detection device 1000 to design a longer flow path for air circulation based on a smaller area size. It is worth mentioning that when the air velocity is too large, the turned air duct 30 can reduce the air velocity to prevent the highly circulating air from affecting the detection result. In this example, the height direction refers to the Z-axis direction, and the area size refers to the size of the air quality detection device 1000 in the plane where the XY axis is located.

In this way, the volume of the accommodating cavity 100 occupied by the air duct 30 can be saved. The accommodating cavity 100 of the casing 10 leaves more installation space for other components. Of course, it can be understood that the second air duct 32 may also be designed as a structure with other shapes, such as an S-shape. Further, in this example, the second air duct 32 provides a corner, and the air turns at least 90 degrees before and after passing the corner of the second air duct 32.
通过这样的方式，所述空气质量检测装置1000的流速能够被稳定在一个较为均衡的水平，比如说在本示例中，在所述抽气单元21和所述检测单元23之间的所述风道30的压力能够被维持在1.934e+002Pa至2.580e+001Pa。所述抽气单元21和所述检测单元23之间的所述风道30的流速能够被维持在小于6.304e+000米每秒。可选地，在本发明的一些示例中，所述抽气单元21和所述检测单元23之间的所述风道30的流速能够被维持在小于3.152e+000米每秒以有利于所述检测单元23处于一平稳的工作环境中。In this way, the flow velocity of the air quality detection device 1000 can be stabilized at a relatively balanced level.

值得一提的是，所述第二风道32被设置为自宽变窄的一流道以保证空气在所述第二风道32内的流速或者说经过所述检测单元23时的流速。It is worth mentioning that the second air duct 32 is set as a first-rate duct with a narrowed width to ensure a flow velocity of the air in the second air duct 32 or a flow velocity when passing through the detection unit 23.
更加具体地说，所述第二风道32具有一第一端和一第二端，其中所述第一端被连接于所述第二风道32，其中所述第二端被连接于所述出风口102，其中所述第二流道的流道截面积被设置为沿着所述第一端至所述第二端减小的，以增大所述第二流道的压力，从而使得空气保持一较为稳定的流速通过所述检测单元23。所述空气质量检测装置1000进一步包括一过滤单元40，其中所述过滤单元40用于对于进入所述风道30的空气进行过滤以去除部分杂质，比如说一些毛发，灰土等，这些杂质一旦进入到所述风道30内，可能造成所述风道30堵塞或者是对于所述空气检测主体20的检测质量造成影响。在本实施例中，所述过滤单元40位于所述入风口101和所述抽气单元21之间以使空气在达到所述抽气单元21之前被所述过滤单元40过滤。所述过滤单元40可以是一滤网。可选地，所述过滤单元40被可拆卸地安装于所述风道30以方便及时更换所述过滤单元40以防止所述风道30在所述过滤单元40处发生堵塞。More specifically, the second air duct 32 has a first end and a second end, wherein the first end is connected to the second air duct 32, and the second end is connected to the second air duct 32.
