A humidity detection module is disposed on the surface of the device body; the humidity detection module is electrically connected to the control module; the humidity detection module is used to detect the humidity of the environment in which the air quality detection module is located and output a humidity detection signal. The control module is also used to control the first communication module to send temperature detection signals and humidity detection signals to an external terminal so that the external terminal can calculate the temperature and humidity values.

[0010] The present invention also proposes an air quality detection system, which includes an external terminal and a wearable finger device as described in any of the preceding claims.

[0011] In one embodiment, the external terminal includes a control device and a second communication module electrically connected to the control device.

[0012] In one embodiment, the control device is configured to: Based on the comparison result between the air quality detection signal received by the second communication module and the corresponding preset air quality threshold, the air quality of the environment in which the finger wearable device is located is determined. If the first air quality value corresponding to the air quality detection signal is less than the corresponding preset air quality threshold, it is determined that the air quality of the environment in which the finger-wearable device is located is unqualified.

Furthermore, the control module also receives operational control signals from an external terminal via the first communication module and outputs corresponding detection control signals to enable the air quality detection module to execute the corresponding air quality detection mode.

[0023] As people pay increasing attention to their health, the number of people spontaneously purchasing health monitoring products is also rising. Consequently, a plethora of health monitoring products are emerging on the market, such as smartwatches, smart bracelets, smart glasses, and smart rings. Among these, smart rings are currently the newest and most fashionable accessory, allowing for the measurement of various health parameters with almost no wearing sensation.

[0024] Currently, due to size limitations, smart rings primarily use sensors to directly monitor human health parameters, allowing users to understand their body's various indicators in real time. However, current smart rings lack the ability to detect the air quality in the user's environment, preventing them from identifying harmful air pollution before the user experiences any health issues.

[0025] To address the above problems, the present invention proposes a finger-wearing device, the finger-wearing device comprising: Equipment body 10; The control module 20 is located inside the device body 10; An air quality detection module 30 is disposed on the outer peripheral surface of the device body 10; the air quality detection module 30 is electrically connected to the control module 20; the air quality detection module 30 is used to execute the corresponding air quality detection mode and output the corresponding air quality detection signal when it receives the detection control signal output by the control module 20. The first communication module 40 is disposed inside the device body 10; the first communication module 40 is electrically connected to the control module 20, and the first communication module 40 is communicatively connected to an external terminal. The control module 20 is used to receive the working control signal input from the external terminal via the first communication module 40 and output the corresponding detection control signal, and is also used to control the first communication module 40 to send the air quality detection signal to the external terminal so that the external terminal can calculate the air quality value.

[0026] It is understandable that the wearable device for fingers can be a ring, a finger sleeve, or similar device. In this case, the wearable device is implemented using a ring, meaning the device body 10 is the ring body. Furthermore, the device body 10 has a corresponding receiving cavity inside to accommodate the corresponding modular structure.

[0027] In this embodiment, the control module 20 can be implemented using a main controller, such as a DSP (Digital Signal Processor), MCU (Microcontroller Unit), FPGA (Field Programmable Gate Array), or SOC (System on Chip). The control module 20 is located inside the device body 10, specifically within a cavity inside the device body 10.

[0028] In this embodiment, the air quality detection module 30 can select the corresponding sensor according to the type of air to be detected. For example, a laser scattering sensor can be used to detect the concentration of particulate matter in the air; a micro electrochemical sensor can be used to detect toxic gases such as carbon monoxide and nitrogen dioxide in the air. When the air quality detection module 30 needs to detect multiple different air types, a sensor that integrates the detection of multiple air types, such as the BME690 sensor, needs to be used. Furthermore, to enable the air quality detection module 30 to detect multiple different air types one by one, it needs to be electrically connected to the control module 20. Upon receiving the detection control signal output by the control module 20, the corresponding air quality detection mode is executed, and the corresponding air quality detection signal is output to the control device. The air quality detection mode includes at least one of a particulate matter detection mode, a pollutant detection mode, and a volatile organic compound detection mode.

[0029] In this embodiment, the first communication module 40 can be implemented using a Bluetooth communication device, a short-range communication module, or the like. By electrically connecting the first communication module 40 to the control module 20 and communicating with an external terminal, the communication connection between the control module 20 and the external terminal is achieved. Based on this, the control module 20 can send the received air quality detection signal to the external terminal via the first communication module 40, or receive the operating control signal input from the external terminal via the first communication module 40, thereby controlling the air quality detection module 30 to execute the corresponding air quality detection mode.

[0030] By employing a wearable finger device comprising a device body 10, a control module 20, an air quality detection module 30, and a first communication module 40, the functionality of the wearable finger device can be effectively improved. The control module 20 and the first communication module 40 are located inside the device body 10, while the air quality detection module 30 is located on the outer peripheral surface of the device body 10, effectively utilizing the configurable structure on the device body 10 based on the module's own operating characteristics. By electrically connecting the air quality detection module 30 to the control module 20, the air quality detection module 30 receives the detection control signal output by the control module 20 and executes the corresponding air quality detection mode. This causes the air quality detection module 30 to output a corresponding air quality detection signal to the control module 20, which then transmits the air quality detection signal to an external terminal via the first communication module 40 for the external terminal to calculate the air quality value. In addition, the control module 20 also receives the working control signal input from the external terminal via the first communication module 40 and outputs the corresponding detection control signal so that the air quality detection module 30 executes the corresponding air quality detection mode, thereby enabling the wearable device to only perform detection without performing signal analysis, thus avoiding setting too many device modules on the device body 10.

[0031] In one embodiment of the present invention, the control module is configured as follows: Based on the working control signal received by the first communication module, the air detection time period is confirmed; Based on the air quality detection time period, the air quality detection module is controlled to start and stop working accordingly.

[0032] Understandably, to prevent excessive battery drain in wearable devices, the detection period of the air quality detection module 30 can be set. For example, if the user's work environment may have substandard air quality, the detection period of the air quality detection module 30 can be set to match the user's work hours. The user can output a corresponding work control signal to the first communication module 40 via an external terminal. The first communication module 40 then outputs this work control signal to the control module 20, which in turn determines the air quality detection period based on the work control signal. The control module 20 can then determine when the air quality detection module 30 starts and stops working based on the air quality detection period. For example, if the air quality detection period is from 9:00 to 18:00, the control module 20 will start the air quality detection module 30 at 9:00 and stop it at 18:00.

[0033] In one embodiment of the present invention, the air quality detection module has multiple presets corresponding to the air quality detection mode; the control module is further configured to: In response to the working control signal received by the first communication module, the air quality detection module is controlled to cyclically execute multiple air quality detection modes in a preset order; Based on multiple air quality detection modes, multiple air quality detection signals are acquired, and the first communication module is controlled to send multiple air quality detection signals to an external terminal so that the external terminal can calculate the air quality value corresponding to the multiple air quality detection signals.

[0034] It is understandable that, in order for the wearable device to confirm different types of air quality in the external environment, the air quality detection module 30 needs to be equipped with or integrate multiple air quality detection modules corresponding to different types. Furthermore, to reduce the power consumption of the air quality detection module 30, it is necessary to limit the air quality detection module 30 to detecting only one type of air quality at a time. In addition, controlled by the above, the control module 20 receives the air quality detection signal output by the air quality detection module 30 and outputs it to an external terminal via the first communication module 40. The external terminal confirms the uploaded air quality detection signal to determine whether to send the corresponding co-operation control signal to the wearable device. If the external terminal confirms that the air quality corresponding to the uploaded air quality detection signal is unqualified, the external terminal will output a prompt signal to remind the user to leave the current area. During this period, the air quality detection module 30 will continue to execute this air quality detection mode and upload the corresponding air quality detection signal to the external terminal via the first communication module 40, so that the external terminal can continuously confirm whether the air quality of the user's environment is qualified based on the air quality detection signal. Under the condition that the air quality detection signal uploaded in the current air quality detection mode is confirmed to be qualified, the external terminal will send a work control signal to the wearable device, so that the air quality detection module 30 can perform the corresponding work based on the work control signal.

[0035] In this embodiment, the control module 20 receives a working control signal from an external terminal via the first communication module 40, thereby controlling the air quality detection module 30 to cyclically execute multiple air quality detection modes in a preset order and upload the corresponding air quality detection signals to the external terminal one by one. This allows the external terminal to confirm various types of air quality based on the multiple air quality detection signals. It is understood that the air quality detection module 30 will only cyclically execute multiple air quality detection modes and output multiple corresponding air quality detection signals in a preset order if all the air quality detection signals received by the external terminal are within acceptable limits. This allows the external terminal to calculate the corresponding air quality value based on the multiple corresponding air quality detection signals.

[0036] In one embodiment of the present invention, the finger-wearing device further includes: A temperature detection module 50 is disposed on the surface of the device body 10; the temperature detection module 50 is electrically connected to the control module 20; the temperature detection module 50 is used to detect the temperature of the environment in which the air quality detection module 30 is located and output a temperature detection signal. A humidity detection module 60 is disposed on the surface of the device body 10; the humidity detection module 60 is electrically connected to the control module 20; the humidity detection module 60 is used to detect the humidity of the environment in which the air quality detection module 30 is located and output a humidity detection signal. The control module 20 is also used to control the first communication module 40 to send temperature detection signals and humidity detection signals to an external terminal so that the external terminal can calculate the temperature and humidity values.

[0037] Understandably, high temperature and humidity environments significantly impact the measurement accuracy of air quality sensors. For example, water molecules adsorbed on the surface of MOx-sensitive materials alter their resistance, leading to misinterpretations of VOC concentration changes. High humidity causes a decrease in resistance, which is then mistakenly interpreted as an increase in reducing gas concentration. Temperature not only directly affects the sensor's physicochemical response but also alters the form, diffusion rate, and chemical reaction equilibrium of pollutants in the air. Therefore, to ensure that external terminals can accurately confirm the corresponding air quality value after receiving the air quality detection signal, it is necessary to verify the humidity and temperature of the environment in which the wearable device is located. This information is then used to correct the air quality value corresponding to the detection signal, preventing erroneous readings from the external terminal.

[0038] In this embodiment, the temperature detection module 50 can be implemented using a discrete digital output temperature sensor. It detects the temperature of the external environment of the wearable device and outputs a temperature detection signal to the control module 20, which then uploads the temperature detection signal to an external terminal via the first communication module 40. The humidity detection module 60 can be implemented using a polymer capacitive sensor. It detects the relative humidity of the external environment of the wearable device and outputs a humidity detection signal to the control module 20, which then uploads the humidity detection signal to an external terminal via the first communication module 40. It is important to note that to ensure the air quality detection signal, humidity detection signal, and temperature detection signal acquired by the external terminal are at the same time, the control module 20 needs to output a corresponding clock signal to calibrate the detection times of the air quality detection signal, humidity detection signal, and temperature detection signal, thereby ensuring that the humidity detection signal and temperature detection signal calibrated by the external terminal correspond.

[0039] This invention also proposes an air quality detection system, which includes an external terminal and a wearable finger device as described in any of the preceding claims. It is worth noting that since the air quality detection system of this invention is based on the aforementioned wearable finger device, the embodiments of the air quality detection system of this invention include all the technical solutions of all the embodiments of the aforementioned wearable finger device, and the achieved technical effects are completely identical, and will not be repeated here. In this embodiment, the external terminal can be a mobile phone or a smartwatch, etc.

[0040] In one embodiment of the present invention, the external terminal includes a control device and a second communication module electrically connected to the control device. The second communication module is communicatively connected to the control module via the first communication module. The second communication module is used for the control device to communicate with the finger wearable device.

[0041] In this embodiment, the control device can also be implemented using a main controller, such as a DSP (Digital Signal Processor), MCU (Microcontroller Unit), FPGA (Field Programmable Gate Array), or SOC (System-on-Chip). The second communication module needs to be implemented using a device corresponding to the first communication module. For example, if the first communication module uses a Bluetooth communication module, the second communication module also needs to be implemented using a Bluetooth communication module; if the first communication module uses a short-range communication module, the second communication module also needs to be implemented using a short-range communication module, thereby ensuring the communication connection between the wearable device and the external terminal.

[0042] In one embodiment of the present invention, the control device is configured as follows: Based on the comparison result between the air quality detection signal received by the second communication module and the corresponding preset air quality threshold, the air quality of the environment in which the finger wearable device is located is determined. If the first air quality value corresponding to the air quality detection signal is less than the corresponding preset air quality threshold, it is determined that the air quality of the environment in which the finger-wearable device is located is unqualified.

[0043] In this embodiment, the external terminal receives the air quality detection signal uploaded by the wearable device via the second communication module, and compares the air quality signal with the corresponding preset air quality threshold to determine the air quality of the environment in which the wearable device is located. It is understood that multiple preset air quality thresholds are set in the external terminal to correspond to multiple air quality detection modes in the wearable device. Therefore, if the first air quality value corresponding to any set of air quality detection signals is less than the corresponding preset air quality threshold, it is determined that the air quality of the environment in which the wearable device is located is unqualified.

[0044] Furthermore, the control device is also configured to: If the air quality of the environment in which the wearable device is located is determined to be substandard, a warning signal will be output.

[0045] If the first air quality value corresponding to any set of air quality detection signals is less than the corresponding preset air quality threshold, it is determined that the air quality of the environment where the wearable device is located is unqualified, and a prompt signal is output to prompt the user to leave the current area.

[0046] Optionally, the wearable device includes a temperature detection module disposed on the surface of the device body; the temperature detection module is electrically connected to the control module; the temperature detection module is used to detect the ambient temperature where the air quality detection module is located and output a temperature detection signal; a humidity detection module disposed on the surface of the device body; the humidity detection module is electrically connected to the control module; the humidity detection module is used to detect the ambient humidity where the air quality detection module is located and output a humidity detection signal; the control device is further configured to: Based on the temperature detection signal and humidity detection signal received by the second communication module, the humidity and temperature of the environment in which the finger wearable device is located are confirmed; Based on the air quality detection signal, the humidity and temperature of the environment where the finger-wearing device is located, the first air quality value is corrected to obtain a second air quality value.

[0047] In this embodiment, the external terminal will also correct the corresponding air quality detection signal based on the temperature and humidity detection signals uploaded by the wearable device. The method for correcting the first air quality value based on the air quality detection signal, the humidity and temperature of the environment where the wearable device is located needs to be selected and set according to the specific type of air quality detection module used, thereby obtaining the corrected second air quality value.

[0048] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
