Since indoor air does not flow smoothly outdoors, the concentration of inhalable pollutants is usually far higher than the standard allowable concentration and is easily perceived by people. For example, formaldehyde in secondary decoration or formaldehyde in newly-added furniture in a certain room, and a fire disaster in a kitchen, for example, is difficult to detect in a bedroom, and smoke can not be found by a fire sensor in the room until the smoke drifts into the room when the fire disaster is great.
And in the prior art, a fire sensor identifies a fire by means of images or infrared rays, but inhalable pollutants are generated when the fire happens or is about to happen.
Therefore, how to rapidly, sensitively and accurately detect the concentration value of the inhalable pollutants in the room is a technical problem to be solved by the application.
The invention conception of the application is as follows:
the inventor of the present application has found, when studying the above problems, that there are several important key points to solve the above problems:
firstly, indoor air mobility is poor, and the inhalable pollutants are generally random in production place, and can't reliably predict, and when the inhalable pollutants was far away from the sensor, the sensor can only detect when the actual concentration of inhalable pollutants has been higher. Namely, the problem that the inhalable pollutants cannot be rapidly and uniformly diffused needs to be solved.
Secondly, how to uniformly detect different kinds of inhalable pollutants by different detection methods?
Thirdly, the common sensors are arranged at fixed positions, and cannot be linked with a user. Namely, how to solve the problem of flexibly arranging the sensors by taking the position of the user as a core detection point.
In view of the above problems, the inventors of the present invention have carefully analyzed and compared the above problems and found that some desktop or vertical air conditioning devices, such as air humidifiers and water-washing air conditioning fans, can effectively adsorb dust in air when they emit water mist or water vapor into the air. The inventors of the present application have therefore creatively found that the first problem can be effectively solved by filling the air with an adsorbent to adsorb the inhalable pollutants and then actively delivering the air with the adsorbent to the sensor by establishing a wind field. And the gasified adsorbent can absorb various inhalable pollutants, and the sensor can uniformly identify the various pollutants by detecting the change of the adsorbent, so that the second problem is solved. Secondly again, desk-top or vertical air conditioning equipment can carry in a flexible way, and the user only needs arrange it in its space, can the air in space of conditioning, can in time carry out the early warning to the air quality again, kills two birds with one stone, has also solved above-mentioned third problem.
The following describes the specific steps of the air anomaly warning method provided by the present application in detail with reference to several embodiments.

As shown in fig. 1a, there are two air-conditioning apparatuses in the space, namely an air-conditioning apparatus 101 and an air-conditioning apparatus 102. The flow schematic of their respective wind farm fluids is shown in fig. 1 a. The two air conditioning devices can be added with an adsorbent liquid storage tank, and the air blower of the air conditioning device blows air into the liquid storage tank to accelerate the evaporation or gasification of the adsorbent, so that the adsorbent is injected into the wind field, and the types of the adsorbent in the two air conditioning devices can be the same or different.
The adsorbent includes: water, alcohol, dry ice, nano-scale activated carbon, and the like.
Similarly, as shown in fig. 1b, the desktop or vertical water washing air conditioner 103 adds an adsorbent into its water tank, so that the adsorbent evaporates or gasifies into the wind field along with the moisture.
The circulating wind field takes the air conditioning equipment as a circulation starting point, and returns the air absorbed with the inhalable pollutants to a sensor arranged inside the air conditioning equipment for detection. And when the detected inhalable pollutant concentration is greater than a preset threshold value, sending early warning prompt information to a user.
A specific air anomaly warning method is described below.

The purpose of this is to make the wind field form a circulating wind field with the air conditioning equipment as the start and stop point of the cycle.
The air blown out by the blower of the air blowing module can firstly pass through the liquid storage tank which stores the adsorbent, so that the evaporation of the adsorbent is accelerated.

When the adsorbent carries the inhalable pollutants and touches the sensor, the sensor can detect the concentration value of the inhalable pollutants.
In one possible design, the sorbent chemically reacts with the inhalable contaminants such that the intrinsically invisible inhalable contaminants become visible gas, or mist, so that the sensor can use its visibility to acquire an image or use the laser scattering principle to identify the concentration of the inhalable contaminants.
S203, if the concentration value meets the preset condition, sending early warning information.
In the step, when the concentration of the inhalable pollutants is greater than the preset threshold value, the user is informed through means such as APP, voice or buzzer, a display panel and the like, the situation that the air quality is abnormal possibly occurs at the moment, and the user is informed to check whether the surrounding environment has potential safety hazards or not, if yes, whether the potential fire hazards exist or not.
In a possible design, in order to prevent the sensor from fluctuating due to unknown reasons, such as temperature drift, the warning message is generated only when m concentration values are continuously detected to be greater than a preset threshold value.
It should be noted that, for the specific value of m, a person skilled in the art can select it according to the actual situation, and the application is not limited.
According to the air abnormity early warning method provided by the embodiment, an air field construction instruction is sent to the air blowing module, the air field construction instruction is used for controlling the air blowing module to construct a target air field in a target space, a gaseous adsorbent is added into the target air field, the adsorbent is used for adsorbing inhalable pollutants in the air, then a concentration value of the inhalable pollutants in the air is obtained, the adsorbent is contained in the air, and if the concentration value meets a preset condition, early warning information is sent. The technical problem of how to accurately and sensitively discover the indoor air quality abnormity is solved. The technical effect of improving the detection sensitivity and accuracy is achieved by combining the diffusion effect of the wind field and the adsorption effect of the adsorbent
