Theelastic body 80 has an upper surface 85 , an elastic body bottom 86 and ahole 84 . Theelastic body 80 protrudes downward from the upper surface 85 to the bottom 86 of the elastic body. One opening of thehole 84 is located on the upper surface 85 . Thetrigger member 81 has atop end 82 and abottom end 83 . The top 82 has afirst trigger end 87 and asecond trigger end 88, thesecond trigger end 88 is arranged around thefirst trigger end 87, and there is a trigger end gap between thesecond trigger end 88 and thefirst trigger end 87 89, wherein thefirst trigger end 87 has a compressible length.

The first confirmingpart 24 and the second confirmingpart 25 can be strip-shaped or dot-shaped. Thefirst confirmation part 24 and thesecond confirmation part 25 respectively have a protruding outer surface. The first confirmingpart 24 and the second confirmingpart 25 are used to assist a user to confirm whether a finger is in contact with the first confirmingpart 24 and the second confirmingpart 25 at the same time, so as to ensure the integrity of the finger pressing.

Please also refer to FIG. 11 , which is a schematic cross-sectional view of the embodiment shown in FIG. 9 when the user presses down with his finger. In the present invention, by selecting the elastic coefficient of theelastic body 80, when a user presses down the light-transmittingupper cover 22 with a finger, the pressure is greater than a lower limit of a pressure threshold and smaller than an upper limit of a pressure threshold (the present invention selects the elastic coefficient of theelastic body 80 The coefficient of elasticity can make the pressure under this moment be large enough, and it is less likely that there will be a gap between the finger and the light-transmittingupper cover 22 to cause light leakage, and the pressure under this moment will not be too large, so that the microvascular deformation in the finger will not cause blood The flow is uneven or not smooth, which can reduce the measurement error. In order to be suitable for measuring the blood oxygen concentration under pressure), theelastic body 80 is deformed, so that thekeycap 2 is displaced downward, and thefirst trigger end 87 is contacted and triggered The first trigger part 75 (for example, thefirst trigger part 75 is two wires, the first trigger end 87 contacts the two wires of thefirst trigger part 75 at the same time, and makes the two wires conduct), and at this time the second Thetrigger end 88 does not contact thesecond trigger portion 76 . When thefirst trigger terminal 87 continuously contacts and triggers thefirst trigger part 75 during a trigger period (for example, thefirst trigger terminal 87 makes the two wires of thefirst trigger part 75 continuously conduct), and thesecond trigger part 75 is triggered during the trigger period. When theend 88 does not touch thesecond trigger part 76, theprocessing element 64 passes through a reflected light received by thelight receiver 7 during the trigger period and is transmitted by the twored light emitters 70, 71 and the twoinfrared light emitters 72, 73. The emitted light is respectively emitted, and the ratio of the reflected light to the emitted light is calculated to calculate the blood oxygen concentration of the user. When calculating the blood oxygen concentration, the transmittance of the light-transmittingupper cover 22 to the red light emitted by the twored light emitters 70, 71 and the transmittance to the infrared light emitted by the twoinfrared light emitters 72, 73 can be calculated. Transparency is taken into consideration. During the triggering period, if the first triggeringend 87 does not continue to touch and trigger the first triggeringpart 75, theprocessing element 64 stops calculating the blood oxygen concentration of the user, and the user must perform the measurement again, because the triggering During this period, the user does not press the light-transmittingupper cover 22 continuously and stably, which may cause errors in blood oxygen concentration measurement. During the triggering period, the user can confirm whether his fingers are in continuous contact with thefirst confirmation part 24 and thesecond confirmation part 25. If he does not touch thefirst confirmation part 24 and thesecond confirmation part 25 continuously, because If the finger is not placed in the correct position, it will affect the accuracy of blood oxygen concentration measurement and may cause errors in blood oxygen concentration measurement. Please also refer to FIG. 12 , which is a schematic cross-sectional view of the specific embodiment of FIG. 9 that the user presses down excessively with fingers. When the user's finger presses down on the light-transmittingupper cover 22 during the trigger period, the pressure is greater than the upper limit of the pressure threshold (the present invention can make the pressure under the pressure greater than the one suitable for measuring the blood oxygen concentration by selecting the elastic coefficient of theelastic body 80. Under pressure, the microvessels in the fingers are easily deformed, making the blood flow uneven or not smooth, thus causing measurement errors), at this time, the length of thefirst trigger end 87 is slightly shortened due to compression, and thekeycap 2 is then downward. Displacement (compared to FIG. 11 ), so that the second trigger end 88 contacts and triggers the second trigger part 76 (for example, thesecond trigger part 76 is two wires, and the second trigger end 88 contacts thesecond trigger part 76 at the same time two wires, and make the two wires conduction), theprocessing unit 64 stops calculating the blood oxygen concentration of the user, and the user must perform the measurement again, because when the pressure of the finger is too large, the amount of blood oxygen concentration will be affected The accuracy of the measurement may cause errors in the measurement of blood oxygen concentration. In some embodiments, thefirst confirmation part 24 and thesecond confirmation part 25 are respectively a sensor for sensing whether the user's finger touches thefirst confirmation part 24 and thesecond confirmation part 25 . When the user's finger does not continuously touch thefirst confirmation part 24 and thesecond confirmation part 25 during the trigger period, theprocessing element 64 stops calculating the blood oxygen concentration of the user, and the user must perform the measurement again. If the finger is not placed in the correct position, it will affect the accuracy of blood oxygen concentration measurement and may cause errors in blood oxygen concentration measurement. In some embodiments, thefirst confirmation portion 24 has a concave outer surface. In some other embodiments, thesecond confirmation portion 25 has a concave outer surface.

When the user presses down the light-transmittingupper cover 22 with his fingers, the pressure is greater than the lower limit of the pressure threshold and less than the upper limit of the pressure threshold (the present invention can make the pressure under this moment large enough by selecting the elastic coefficient of theelastic body 80, and the finger and the transparent It is less likely that there will be gaps between theupper cover 22 to cause light leakage, and the pressure under the pressure will not be too high at this time, so as not to deform the capillaries in the fingers and cause blood flow to be uneven or unsmooth, which can reduce measurement errors and be an appropriate amount. measure blood oxygen concentration), theelastic body 80 deforms, causing thekeycap 2 to displace downward, and makes thesecond trigger end 88 contact and trigger thesecond trigger part 76, and at this time thefirst trigger end 87 is not in contact with Thefirst trigger part 75 . When thesecond trigger end 88 continuously touches and triggers thesecond trigger portion 76 during a trigger period, and thefirst trigger end 87 does not touch thefirst trigger portion 75 during the trigger period, theprocessing element 64 is activated by The reflected light received by thelight receiver 7 and the emitted light respectively emitted by the twored light emitters 70, 71 and the twoinfrared light emitters 72, 73 calculate the ratio of the reflected light to the emitted light to calculate the user's blood oxygen concentration. When the user's finger presses down on the light-transmittingupper cover 22 during the trigger period, the pressure is greater than the upper limit of the pressure threshold (the present invention can make the pressure under the pressure greater than the one suitable for measuring the blood oxygen concentration by selecting the elastic coefficient of theelastic body 80. Under pressure, the microvessels in the fingers are easily deformed, making the blood flow uneven or not smooth, thus causing measurement errors), at this time, the length of thesecond trigger end 88 is slightly shortened due to compression, and thekeycap 2 is then downward. Displacement, so that the first trigger end 87 contacts and triggers thefirst trigger part 75, and theprocessing element 64 stops calculating the blood oxygen concentration of the user, and the user must perform the measurement again, because when the pressure of the finger is too large, it will affect the blood oxygen concentration.
