The number of the air pumps 23 is not limited, and the air pumps 23 may be provided in one-to-one correspondence with the air bags 20. When the air pumps 23 are provided in one-to-one correspondence with the air bags 20, no air valve needs to be provided between the air pump 23 and the air bags 20.

Fig. 6 is another schematic air path diagram of the wrist wearable device in the embodiment of the present application, as shown in fig. 6, in another technical solution, when the wrist wearable device includes at least two air bags 20, only one air pump 23 may be included, and all the air bags 20 are inflated by using one air pump 23. And the air pump 23 is connected with each air bag 20 through the air valve 24. The air valve 24 may be disposed on the fixing band 2. In this scheme, one air pump 23 is used to inflate each air bag 20, and the opening and closing of each air valve 24 are controlled to control which air bag 20 is inflated by the air pump 23. The wrist wearable device only comprises one air pump 23, and the air pumps 23 occupy less space when the number of the air pumps 23 is small, which is beneficial to reducing the cost.

Referring to fig. 1 and 3, the airbag 20 includes a sensing airbag 21 and a pressing airbag 22. Specifically, the sensing airbag 21 and the pressing airbag 22 are sequentially disposed in a direction toward the wrist of the user in the fastening band 2, and it is also conceivable that the sensing airbag 21 and the pressing airbag 22 are sequentially disposed inside the fastening band 2. When equipment body 1 has the display module assembly, the display surface of display module assembly is located the direction that wearable equipment of wrist formula deviates from the user wrist, or said differently, the display surface of display module assembly is located the outside of wearable equipment of wrist formula. The sensing airbag 21 and the pressing airbag 22 are located in a direction of the wrist wearable device away from the display surface of the display module, or said, the sensing airbag 21 and the pressing airbag 22 are located inside the wrist wearable device. When the user wears the wrist wearable device 100, the sensing airbag 21 contacts the wrist of the user, and the pressing airbag 22 is located between the sensing airbag 21 and the fixing band 2. The fixing band 2 is provided with an air pump 23, an air valve 24, a pressure gauge 25 and a blood pressure detection control board 26. The air pump 23 is connected to the sensitive airbag 21 and the pressing airbag 22 through an air valve 24, so that the air pump 23 can introduce air into the sensitive airbag 21 and the pressing airbag 22. The pressure gauge 25 is connected to the sensing balloon 21, so that the pressure in the sensing balloon 21 can be detected, thereby realizing the function of blood pressure detection. In this embodiment, the sensing balloon 21 is used to connect to a pressure gauge 25 for detecting the pressure in the blood vessel. The air pump 23 inflates the pressing balloon 22 to occlude blood in the blood vessel. In this solution, at the beginning of the detection, a small amount of gas is filled into the sensing balloon 21, so as to detect the pressure in the blood vessel more reliably.

The volume of the sensing air bag 21 can be designed through an experimental design method, so that the accuracy of the sensing air bag 21 in detecting the blood pressure is improved.

The air bag 20 is substantially in the shape of a strip, and the side of the air bag 20 along the extending direction of the fixing band 2 is a linear side. Specifically, the length of the air bag 20 in the extending direction of the fixing belt 2 may be made larger than the length of the air bag 20 in the direction perpendicular to the extending direction of the fixing belt 2. In this scheme, can promote the effective width of pressing after the gasbag is aerifyd, be favorable to forming effective blocking to promote blood pressure test's accuracy.

The width of above-mentioned gasbag can be 23mm, and the number of times of inflating and deflating >10000 times, and gasbag thickness is 0.8mm, and the fixed band with the thickness of gasbag with can be 3mm, be favorable to realizing the attenuate of fixed band, promote the travelling comfort that the user wore.

In addition, the width of the sensing airbag 21 perpendicular to the extending direction of the fastening tape 2 is less than or equal to the width of the pressing airbag 22 perpendicular to the extending direction of the fastening tape 2, and the width of the pressing airbag 22 perpendicular to the extending direction of the fastening tape 2 is less than or equal to the width of the fastening tape 2 perpendicular to the extending direction of the fastening tape 2. In this scheme, response gasbag 21 can not follow the edge that presses gasbag 22 and expose, presses gasbag 22 and can not follow the edge of fixed band 2 and expose, is favorable to promoting user's wearing wrist formula wearable device 100's travelling comfort and aesthetic feeling. In addition, the fixing belt 2 can protect the sensing airbag 21 and the pressing airbag 22, and the service life of the sensing airbag 21 and the pressing airbag 22 is prolonged.

In this application technical scheme, fixed band 2 and gasbag 20's material is different, can be so that fixed band 2's elastic modulus is less than gasbag 20's elastic modulus. That is, the elasticity of the fixing band 2 is smaller than that of the air bag 20, so that when the air bag 20 is inflated, the pressure generated by the air bag 20 is mainly transmitted to the wrist of the user, and the wrist of the user is effectively pressed.

Fig. 7 is another pneumatic diagram of the wrist wearable device in the embodiment of the present application, and as shown in fig. 7, when the airbag 20 of the wrist wearable device 100 includes the pressing airbag 22 and the sensing airbag 21, the wrist wearable device 100 may include one air pump 23 and two air valves 24, that is, the number of the air valves 24 corresponds to one of the airbags 20.

In this embodiment, one air pump 23 may be used to inflate both air bags, and specifically the air valve 24 may be used to control which air bag the air pump 23 inflates. The number of the air pumps 23 included in the wrist wearable device 100 can be reduced, and the space occupied by the air pumps can be reduced. In addition, the air pump may be a micro air pump, and specifically, the volume of the micro air pump may be 12.5mm by 2.5mm, so as to reduce the space occupied by the air pump. The power consumption of the micro air pump can be reduced.

Fig. 9 is a schematic diagram of a usage state of the wrist wearable device in the embodiment of the present application, and as shown in fig. 9, when a user needs to detect blood pressure, the user can lift the wrist wearing the wrist wearable device 100 to the height of the heart of the user, and then start to detect the blood pressure of the user.

Based on the same technical concept, the application also provides a control method of the wrist type wearable device. Taking the design of the wrist wearable device of fig. 7 as an example, a specific control method of the wrist wearable device according to the embodiment of the present application is described below. Fig. 10 is a control flowchart of the wrist wearable device in the embodiment of the present application, and as shown in fig. 10, the control method after starting the detection includes: controlling the air pump to start; and then, controlling the first air valve to open, controlling the second air valve to close, and controlling the air pump to inflate the sensing air bag for a set time, wherein the set time can be specifically 0.1s, the specific duration can be set according to actual conditions, and the air quantity in the sensing air bag is required to be enough to enable the sensing air bag to be attached to the wrist of a user. And then the first air valve is controlled to be closed, the second air valve is controlled to be opened, the air pump is controlled to stop inflating the sensing air bag, and the pressing air bag starts to inflate. In the process that the air pump inflates the pressing air bag, when the pressure meter detects that pulse waves appear, the blood vessel is considered to be pressed, and at the moment, the pressure meter detects the pressure of the sensing air bag and serves as the diastolic pressure of a user; the air pump continues to inflate the pressing air bag, when the pressure gauge detects that the pulse wave disappears, the blood flow in the blood vessel is considered to be completely blocked, and at the moment, the pressure gauge detects the pressure of the sensing air bag as the systolic pressure of the user.
