Detailed Description

The utility model will now be described with reference to the accompanying drawings, which are only exemplary and do not constitute a limitation of the utility model and its applications.

As shown in fig. 1, an air detection device 1 according to the present utility model may include a plurality of detection modules 10, 20, 30 for detecting a plurality of air-related parameters, and a base 50 connected to the plurality of detection modules 10, 20, 30. The base 50 may house a main control board 60 (shown in fig. 4) for controlling the operation of the detection module. The plurality of detection modules 10, 20, 30 may be connected to the base 50 in a pluggable manner independently of each other. In the exemplary embodiment shown in fig. 1, the plurality of detection modules includes a first detection module 10, a second detection module 20, and a third detection module 30. Of course, the number of detection modules is not limited thereto, and the air detection device 1 may include other numbers of detection modules.

The first, second and third sensing modules 10, 20 and 30 include first, second and third housings 12, 22 and 32, respectively, which house sensing sensors. The first housing 12 may have a large volume and may house a PM2.5 detection sensor S1 (shown in fig. 4) requiring a large ventilation area. The volume of the second housing 22 may be larger than the volume of the third housing 32 and smaller than the volume of the first housing 12, and the second housing may house the CO2 detection sensor S2 and the TVOC (volatile organic compound) detection sensor S3 (shown in fig. 4). The third detection module 30 may house a temperature and humidity sensor S4 (shown in fig. 4). The first to third detection modules 10 to 30 can form the air detection device 1 together in a shape-corresponding manner, thereby providing an air detection device that is compact and of small design. For example, the PM2.5 detection sensor S1 may be a commercially available PMs7003 type sensor, the CO2 detection sensor S2 may be a commercially available MTP40 type sensor, the TVOC detection sensor S3 may be a commercially available MMD1013C type sensor, and the temperature and humidity sensor S4 may be a commercially available SHTC3 type sensor, although the present utility model is not limited thereto, and any other type sensor may be employed as long as it can detect the corresponding air parameter.

Preferably, as shown in fig. 1, the first, second and third housings 12, 22 and 32 may be connected to the base 50 through a USB interface. In this way, the pluggable connection of the first housing 12, the second housing 22, and the third housing 32 to the base 50 can be easily achieved. For example, in the case of connection using a pin interface, it is necessary to use a large insertion force to achieve connection and if the insertion force is too large, the protruding pin is easily damaged, so that the use of a USB interface can avoid the interface from being damaged and achieve convenient and quick connection.

As shown in fig. 2, the first, second and third housings 12, 22 and 32 may be formed with a plurality of through holes 14, 24 and 34, respectively, to enable air outside the housings to flow through the through holes to the detection sensors within the housings. With continued reference to fig. 2, the first housing 12 may also be formed with an air inlet and an air outlet and the interior of the first housing 12 may house a fan that may facilitate external air flowing into the interior of the first housing via the air inlet and exiting the first housing via the air outlet. Of course, the air inlet and the air outlet may be provided on other housings.

Preferably, the detection sensors with similar service lives may be arranged in the same housing. For example, a CO ₂ detection sensor S2 and a TVOC detection sensor S3 may be disposed in the second housing 22. In this way, both detection sensors can be replaced by simply replacing one detection module and effectively.

The air detection device 1 may also comprise an alarm device. As shown in fig. 1, the alarm device may be formed as light bands 16, 26 and 36 provided at the outer circumferences of the first, second and third housings 12, 22 and 32, respectively, which may emit a warning/alarm light to prompt a user when pollution occurs in the air quality. For example, the light strip may change from green to red when pollution of the air quality occurs, thereby alerting/alerting the user to the exceeding of air quality parameters. The air detection device may also include a light strip switch 18 (shown in fig. 2) that selectively turns the light strip on or off. The user may turn off the light strip switch according to preference to avoid light pollution, for example, may turn off the light strip switch at night.

As shown in fig. 1, the base 50 may include a display screen 40, and the display screen 40 may be used to display parameter information related to air, date, time, and other related information. Thus, the user can view the relevant parameters of the indoor air and other external information in real time. In addition, the base 50 may be provided with a built-in power source such as a lithium battery or an external power outlet to supply power to each detection module.

The control module of the air detection device according to the present utility model will be described in detail with reference to fig. 4.

The main control board 60 may include data input interfaces 62A-D, a data display/output interface 64, a strip control interface 66, a strip switch interface 68, a network interface 63, a power supply interface 65, and a controller 67. The light strip control interface 66 and the light strip switch interface 68 may be coupled to the light strips 16, 26, and 36, the data input interfaces 62A-D may be coupled to the detection sensors S1-S4, respectively, and the data display/output interface 64 may be coupled to the display screen 40.

The controller 67 may be configured to change the light of the light band from a first color to a second color through the light band control interface 66 when the parameter information related to air received from the detection sensors S1-S4 through the data input interfaces 62A-D exceeds a threshold. For example, when the PM2.5 air quality parameter detected by the PM2.5 detection sensor S1 exceeds a threshold, the controller 67 receives this information through the input interface 62A and accordingly changes the light of the light strip 16 of the first detection module 10 from a first color (e.g., green) to a second color (e.g., red) through the light strip control interface 66, so that the user can conveniently determine the air quality status from the color of the light strip even when located far from the air detection apparatus 1.

The controller 67 may be configured to turn off the light strip upon receiving a turn-off signal through the light strip switch interface 68, and may also be configured to output parameter information related to air received from the respective detection sensors through the data input interfaces 62A-D to the display screen 40 via the data display/output interface 64. The controller 67 may also determine that power is being supplied by the internal power source and/or the external power source via the power supply interface 65.

In addition, the controller 67 may be configured to send the air quality parameter information received from the various detection sensors via the data input interfaces 62A-D to a network server via the network interface 63, which may be connected to the intelligent electrical device to control the intelligent electrical device to operate accordingly in accordance with the received air-related parameter information. And the network server can also store parameters related to air and generate an air quality report, and a user can check the parameter information related to air or the air quality report through a mobile phone, so that the user can conveniently select a reasonable treatment scheme according to the air quality condition.

The air detection device according to the present utility model can provide the user with various information about the parameters related to the air. And when the performance decay occurs with time, the performance decaying detection module can be easily replaced by simply pulling the detection module out of the base and inserting a new detection module, and when the replacement is performed, one detection module of the plurality of detection modules can be individually replaced without affecting the operation of the other detection modules, so that the replacement can be performed in a cost-effective manner. In addition, the air detection device provided by the utility model is compact in structure and small in size, and can be conveniently placed in various indoor areas, such as on a table top.

Although exemplary embodiments of the present utility model have been described in detail herein, it is to be understood that the utility model is not limited to those precise embodiments described and shown herein, and that other modifications and variations may be effected by one skilled in the art without departing from the spirit and scope of the utility model.
