In order to facilitate understanding of the blood pressure wristwatch provided in the embodiment of the present application, an application scenario of the blood pressure wristwatch will be described first, and the blood pressure wristwatch can be worn on a wrist of a user to detect body signs such as blood pressure of the user at any time, so as to predict a body state, and thus dangerous secondary symptoms such as stroke caused by hypertension can be effectively avoided.

Referring to fig. 1, a blood pressure wristwatch, generally includes a watch body 10 and an air bag 20; wherein, referring to fig. 5, the watch body 10 may include an air pump 11 and a pressure sensor 12, and the air bag 20 has a first air nozzle 21 and a second air nozzle 22, which are respectively connected to an air outlet of the air pump 11 and an air inlet of the pressure sensor 12. Thus, when the blood pressure is measured, the gas flows from the air pump 11 to the air bag 20, and the pressure sensor 12 directly detects the air pressure in the air bag 20. When the air flows out of the air pump 11, a certain impact force is generated on the air bag 20, so that the air tap of the air bag 20 tends to be separated from the air pump 11; moreover, when the blood pressure is not measured, when a user wearing the blood pressure wristwatch moves or walks around the swing arm, frequent pulling force may be generated between the air bag 20 and the watch body 10, which may cause the air nozzle, the air outlet of the air pump 11 and the air inlet of the pressure sensor 12 to be subjected to frequent force, thereby causing problems of bending, displacement, dust entering and the like, and further causing the air tightness between the air nozzle and the air outlet of the air pump 11 and the air inlet of the pressure sensor 12 to be reduced, thereby affecting the accuracy of the blood pressure measurement.
