DETAILED DESCRIPTION

[0021] Here, the technical solutions in the embodiments (or "implementations") of the present application will be described clearly and completely in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0022] If there are terms involving directional indications or positional relationships in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance.

[0023] The embodiment of the present application provides an air quality detection device. The air quality detection device is a device used to monitor and measure the concentration of various pollutants in the air in the environment, and is mainly used in: environmental monitoring, industrial production, scientific research, home use and other fields, which helps to timely monitor the ambient air quality.

[0024] See also Figure 1 to Figure 2 As shown, the air quality detection device includes an air quality detection module 6 and a humidity control device 10 . The air quality detection module 6 is connected to the humidity control device 10 . The air quality detection module 6 is used to detect the quality of air flowing out of the humidity control device 10 .

[0025] The humidity control device 10 is a device for monitoring and adjusting the humidity level in the air, and is commonly used in the fields of building housing, manufacturing industry, experimental medicine, agriculture, etc., to help maintain a suitable humidity level.

[0026] The humidity control device 10 includes: a shell 1, a heating device 2 and a condenser 3. The shell 1 encloses a chamber 11. The shell 1 is provided with an air inlet 12 connected to the chamber 11 to allow humid air to enter the chamber 11; the heating device 2 is located in the chamber 11 to heat the humid air in the chamber 11; the condenser 3 is located in the chamber 11 and is provided with a condenser cavity 31 to allow high-temperature air heated by the heating device 2 to enter, so as to precipitate some water molecules in the high-temperature air, thereby reducing the water molecule content in the air and achieving the purpose of humidity control.

[0027] The heating device 2 can heat the humid air in the chamber 11 to increase its temperature. The heated high-temperature air enters the condenser chamber 31. Due to the large temperature difference between the high-temperature air and the condenser 3, the water molecules in the air are more likely to reach the dew point, thereby achieving the effect of reducing the water molecule content in the air.

[0028] In some embodiments, the heating device 2 may use heating elements such as a heating wire, a heating tube, or a hot air blower.

[0029] In some embodiments, a heat sink (not shown) is provided on the surface of the condenser 3 so that the temperature of the condenser cavity 31 is close to the external ambient temperature. When the humid air passes through the condenser 3, the humid air will more easily reach the dew point, causing the water vapor in the humid air to condense into liquid water.

[0030] Furthermore, the condenser 3 includes a one-way drain valve (not shown) to drain the liquid water in the condenser cavity 31 while maintaining the airtightness of the condenser cavity 31 .

[0031] In some embodiments, the condenser 3 includes a plurality of metal tubes, through which a cooling medium, such as a refrigerant or other coolant, flows. When the humid air passes through the condenser 3, the cooling medium inside the metal tubes will lower the temperature, causing the water vapor in the humid air to quickly cool and condense into liquid water. The liquid water is collected and discharged outside the system.

[0032] The humidity control device 10 includes: a first humidity sensor 41, which is located between the air inlet 12 and the heating device 2 to detect the humidity of the air entering the chamber 11. Since the first humidity sensor 41 is located between the air inlet 12 and the heating device 2, the humidity of the air entering the chamber 11 can be accurately detected, and interference with humidity measurement by other factors (such as the heating device 2 itself) can be avoided, thereby providing more accurate humidity data.

[0033] In some embodiments, the first humidity sensor 41 is fixed on the housing 1 to detect the humidity of the air entering the chamber 11 .

[0034] In some embodiments, the first humidity sensor 41 may also be directly disposed outside the housing 1 to monitor the humidity of the ambient air.

[0035] In some embodiments, the first humidity sensor 41 may be directly disposed in the chamber 11 without being fixed to the housing 1 .

[0036] In the embodiment of the present application, the number of the first humidity sensor 41 is one.

[0037] In some embodiments, there may be multiple first humidity sensors 41, and the multiple first humidity sensors 41 may be placed at different positions between the air inlet 12 and the heating device 2 to provide more comprehensive and accurate humidity data. By simultaneously monitoring the humidity at multiple positions, the humidity distribution in the environment can be better understood, and the heating device 2 can be adjusted accordingly.

[0038] See also Figure 2 and Figure 4 As shown, the humidity control device 10 includes: a first control device 5 , which is coupled to the first humidity sensor 41 and the heating device 2 to control the operation of the heating device 2 according to the detection result of the first humidity sensor 41 .

[0039] The first humidity sensor 41 can monitor the humidity level of the air in the chamber 11 in real time, and the first control device 5 controls the operation of the heating device 2 according to the detection result of the first humidity sensor 41. When the humidity is lower than the set value, the first control device 5 can turn off the heating device 2; when the humidity exceeds the set value, the first control device 5 can turn on the heating device 2 or take other measures to reduce the humidity.

[0040] The humidity control device 10 includes: a second humidity sensor 42, the shell 1 is provided with an air outlet 13 connected to the chamber 11, the condenser 3 is located between the heating device 2 and the air outlet 13, and the second humidity sensor 42 is located between the air outlet 13 and the condenser 3 to detect the humidity of the air flowing out of the condenser cavity 31.

[0041] In some embodiments, the second humidity sensor 42 is fixed to the housing 1 to detect the humidity of the air flowing out of the condenser cavity 31 .

[0042] In some embodiments, the second humidity sensor 42 may be directly disposed in the chamber 11 without being fixed to the housing 1 .

[0043] In the embodiment of the present application, the number of the second humidity sensor 42 is one.

[0044] In some embodiments, there may be multiple second humidity sensors 42, and the multiple second humidity sensors 42 are placed at different positions between the air outlet 13 and the condenser 3. By simultaneously monitoring the humidity at multiple positions, the humidity of the air flowing out of the condenser cavity 31 can be better monitored, and the heating device 2 can be adjusted accordingly.

[0045] The humidity control device 10 includes a second control device 7 , which is coupled to the second humidity sensor 42 and the heating device 2 to control the operation of the heating device 2 according to the detection result of the second humidity sensor 42 .

[0046] The second humidity sensor 42 can monitor the humidity of the air flowing out of the condenser cavity 31 in real time, and the second control device 7 controls the operation of the heating device 2 according to the detection result of the second humidity sensor 42. When the humidity of the air flowing out of the condenser cavity 31 exceeds the set value, the second control device 7 can turn on the heating device 2 to increase the heating amount of the heating device 2, thereby reducing the air humidity again to within the set value.

[0047] See also Figure 1 and Figure 3 As shown, the air quality detection device includes an air quality detection module 6 for detecting the quality of the air flowing out of the condenser cavity 31. The introduction of the air quality detection module 6 can monitor the quality of the air flowing out of the condenser cavity 31 in real time, and can provide more comprehensive and accurate air quality data, help determine whether the air in the cavity 11 meets specific quality standards, and provide a healthier and more comfortable environment.

[0048] In some embodiments, by monitoring the air quality through the air quality detection module 6, pollutants in the air can be discovered and identified in a timely manner. When pollutants are detected exceeding a preset threshold or standard, corresponding measures can be taken to control and purify the air, such as starting an air purifier or an alarm system, which helps to improve the air quality.

[0049] The air quality detection module 6 includes: a PM2.5 sensor 61 and an air intake pipe 62 , and the air intake pipe 62 connects the condenser cavity 31 and the PM2.5 sensor 61 .

[0050] The PM2.5 sensor 61 can detect and measure the concentration of PM2.5 particles in the air. PM2.5 represents suspended particles in the atmosphere with a diameter less than or equal to 2.5 microns, including dust, pollen, smoke and other fine particles. By monitoring the PM2.5 concentration, more comprehensive and accurate air quality data can be provided to help determine whether the PM2.5 level of the air in the condenser cavity 31 meets the quality standards. The air purifier or other purification equipment can also be started as needed, which helps to reduce the concentration of indoor PM2.5 pollutants, improve air quality, and provide a healthier and more comfortable environment.

[0051] In some embodiments, other sensor combinations may also be used to monitor and detect air quality. For example, temperature sensors, carbon dioxide sensors, volatile organic compound (VOC) sensors, etc. may be used in combination to obtain more comprehensive and integrated air quality data.

[0052] The air quality detection module 6 also includes an exhaust pipe 63, which is connected to the PM2.5 sensor 61 to discharge the detected air into the external environment.

[0053] See also Figure 4 and Figure 5 As shown, humid air enters the chamber 11 from the air inlet 12. When the first humidity sensor 41 detects that the humidity of the humid air is greater than a predetermined value, the first control device 5 controls the heating device 2 to turn on, thereby heating the humid air. The humid air enters the condenser chamber 31 of the condenser 3, and the water molecules in the humid air condense and precipitate. The second humidity sensor 42 detects the humidity of the air flowing out of the condenser chamber 31. The detection value of the second humidity sensor 42 can compensate for the detection result of the PM2.5 sensor 61, or the heating amount of the front-end heating device 2 can be feedback controlled through the second control device 7; then the humid air enters the air quality detection module 6, that is, enters the PM2.5 sensor 61 from the intake pipe 62, and then is discharged to the external environment from the exhaust pipe 63.

[0054] The embodiments of the present application also provide a vehicle, including the above-mentioned air quality detection device. As people have higher and higher requirements for the comfort of vehicle cabins, providing a high-quality cabin air environment not only contributes to the health of occupants, but also helps the driver maintain a good state, thereby helping to reduce the risk of accidents. When the air quality detection device detects that the air quality is lower than the preset value, it can be combined with the corresponding internal and external circulation control strategy and the cleaning filter element to effectively improve the air quality in the vehicle.

The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application should be included in the scope of protection of this application.
