Specifically, the first light emitting element 201, the second light emitting element 202 and the third light emitting element 203 are all installed on one side of the main board 11 close to the skin, the first light emitting element 201, the second light emitting element 202 and the third light emitting element 203 can emit light with a specific wavelength to irradiate the skin, and the first detection unit 110 and the second detection unit 120 receive and detect the light which irradiates the skin and is reflected by the skin, so as to determine the human body physiological parameters of the user.

It should be noted that the principle of detecting physiological parameters of a human body is as follows: the blood reflects light to feed back the blood oxygen heart rate condition, the blood absorbs light with specific wavelength, and the light with the wavelength is absorbed greatly every time the heart pumps blood, so that the light with the wavelength reflected by the skin changes. The reflected light can be obtained by the first detecting unit 110 and the second detecting unit 120 to determine the blood parameters of the human body, such as the pulse, pressure level, blood oxygen value, heart rate value, etc. of the user in the skin, and the related algorithm analysis is performed by the calculation logic unit (not shown) disposed on the main board 11.

Because the first light emitted by the first light-emitting component 201 can be received by the first detection unit 110 and the second detection unit 120 at the same time, and the green reflected light received by the first detection unit 110 and the second detection unit 120 has better signal quality, when the heart rate is calculated, the green light signal received by the first detection unit 110 or the second detection unit 120 can be used alone for calculation, or the heart rate is calculated by referring to the green light signal received by the first detection unit 110 or the second detection unit 120 at the same time, and the influence of ambient light and user movement can be better removed.

In the embodiment of the present invention, the second light-emitting element 202 is a red light source, the third light-emitting element 203 is an infrared light source, the second light-emitting element 202 and the third light-emitting element 203 can emit a second light, the second light is a combination of red light and infrared light, and the second light-emitting element 202 and the third light-emitting element 203 are mainly used for detecting the blood oxygen saturation. The specific principle is that according to the spectral characteristics of oxyhemoglobin and reduced hemoglobin in red light and infrared light regions, the absorption difference of oxyhemoglobin and reduced hemoglobin on red light and infrared light is very large, and the light absorption degree and light scattering degree of blood are related to the blood oxygen saturation (SpO) and the hemoglobin content, so that the contents of oxyhemoglobin and reduced hemoglobin in blood are different, the absorption spectra of blood are also different, and the red light and the infrared light can be adopted for detecting the blood oxygen saturation.

In the embodiment of the present invention, since the second light emitted by the second light emitting element 202 combined with the third light emitting element 203 can be received by the first detecting unit 110 and the second detecting unit 120 at the same time, the sensing area for receiving the second light is increased, and the accuracy of detecting the blood oxygen saturation is improved.

It can be understood that, since the longer the red light transmission route in blood, the better the blood oxygen signal can be obtained (the irrigation index is high), in this embodiment, the distance between the second light-emitting element 202 for emitting red light and the connecting line between the first detecting unit 110 and the second detecting unit 120 is greater than the distance between the first light-emitting element 201 for emitting green light and the connecting line between the first detecting unit 110 and the second detecting unit 120, so that the red light can penetrate deeper subcutaneous tissue to obtain more blood information, and the first detecting unit 110 and the second detecting unit 120 can receive better blood oxygen information.
