[0002] Currently, common blood pressure measurement solutions in smartwatches involve placing an air bladder in the watch band and inflating it using an air pump inside the watch head. This inflates the bladder to compress the user's blood vessels for blood pressure measurement. However, because existing smartwatches lack redundant air passage designs, the air bladder may rupture after inflation due to valve malfunction, significantly reducing the safety of using the smartwatch. Summary of the Invention

[0005] This application also provides a wearable device, the wearable device including: a watch strap mechanism and the watch head mechanism described above; the watch strap mechanism is connected to the housing assembly and has a first airbag communicating with the first external air passage and a second airbag communicating with the second external air passage, and the first airbag and the second airbag can expand or contract under the control of the air pump assembly.

[0006] This application also provides a blood pressure detection method applied to the aforementioned wearable device, wherein the air pump assembly includes: two detection elements, namely a first detection element and a second detection element; the secondary control valve has a first vent port connecting the external atmosphere to the first external air path and the second external air path, and the air pump has a second vent port connecting the main air path and the external atmosphere; or, wherein the air pump assembly includes: two detection elements, namely a first detection element and a second detection element; the air pump assembly further includes: a vent valve having a first vent port, and the first vent port connecting the main air path and the external atmosphere; and the air pump has a second vent port connecting the main air path and the external atmosphere; the blood pressure detection method includes: responding to a blood pressure detection command in a first state or a second state, controlling the first main control valve to open the main air path and the first external air path, controlling the second main control valve to isolate the main air path and the second external air path, controlling the secondary control valve to isolate the first external air path and the second external air path, and closing the first vent port and the second vent port; controlling the air pump to... The first airbag is inflated, and when the first and / or second detection devices detect that the air pressure value of the main air path meets a first preset condition, the first main control valve is controlled to isolate the main air path and the first external air path; the second main control valve is controlled to open the main air path and the second external air path, and the secondary control valve is controlled to isolate the first external air path and the second external air path, so that the air pump inflates the second airbag, and when the first and / or second detection devices detect that the air pressure value of the main air path meets a second preset condition, the air pump is controlled to stop inflating; a blood pressure value is calculated based on some or all of the air pressure values ​​measured by the first and / or second detection devices during the inflation of the first and / or second airbags; the first main control valve is controlled to open the main air path and the first external air path, the second main control valve is controlled to open the main air path and the second external air path, the secondary control valve is controlled to open the first external air path and the second external air path, and the first and second vent ports are opened, so that the first and second airbags deflate.

[0007] The air pump assembly provided in this application, by setting a secondary control valve that can connect to an independent first external air circuit and a second external air circuit, allows the first main control valve connected to the first external air circuit and the second main control valve connected to the second external air circuit to serve as backup valves for each other. That is, when the first main control valve fails, the secondary control valve can connect the first and second external air circuits, guiding the gas from the first external air circuit to the second external air circuit, and then releasing it to the main air circuit through the second main control valve. This reduces the safety risk caused by the inability to release gas due to a failure of the first main control valve, thereby improving the safety of the air pump assembly.

[0031] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0032] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0033] Please see Figures 1 to 2 , Figure 1 This is a partial structural schematic diagram of the wearable device 10 provided in an embodiment of this application. Figure 2 yes Figure 1 A schematic diagram of the structure of the middle strap mechanism 100.

[0034] The wearable device 10 provided in this application can be a smartwatch, a smart bracelet, or a cuff-type blood pressure measuring device, etc. The following example uses a smartwatch as the wearable device 10. Figure 1 As shown, the wearable device 10 includes a strap mechanism 100 and a head mechanism 200. The strap mechanism 100 and the head mechanism 200 are detachably connected and can cooperate with the head mechanism 200 to form a wearing space for the user to wear the device 10 on their wrist. Simultaneously, when the strap mechanism 100 and the head mechanism 200 are detachably connected, the strap mechanism 100 can also communicate with the head mechanism 200 and expand or contract under the control of the head mechanism 200. The head mechanism 200 can integrate various functional components required by the wearable device 10 and can inflate and deflate the strap mechanism 100, allowing it to expand or contract under the control of the head mechanism 200 to facilitate blood pressure measurement. In this embodiment, the air path for inflating and deflating the strap mechanism 100 by the head mechanism 200 has a redundant design, which helps improve the safety of using the wearable device 10.

[0035] The watch strap mechanism 100 can be detachably connected to the watch head mechanism 200 and can expand or contract under the control of the watch head mechanism 200. For example... Figure 2As shown, the watch band mechanism 100 includes a watch band assembly 110 and a connecting assembly 120. The watch band assembly 110 is connected to the connecting assembly 120 and can be detachably connected to the meter head mechanism 200 via the connecting assembly 120. The watch band assembly 110 can also expand or contract under the control of the meter head mechanism 200 to cooperate with the meter head mechanism 200 in measuring the user's blood pressure. The connecting assembly 120 is connected to the watch band assembly 110 and can also be mounted on the meter head mechanism 200 and detachably connected to it, thus achieving a detachable connection between the watch band assembly 110 and the meter head mechanism 200. Simultaneously, when the connecting assembly 120 is assembled with the meter head mechanism 200, it can simultaneously connect the watch band assembly 110 and the meter head mechanism 200, allowing the meter head mechanism 200 to inflate or deflate the watch band assembly 110 via the connecting assembly 120, thereby achieving the expansion or contraction of the watch band assembly 110.

[0036] The inventors discovered that, in addition to a structure for detachable connection with the watch band assembly 110, the watch head mechanism 200 in the relevant solutions also includes a structure for securing the inflation / deflation port of the watch band assembly 110. For example, the watch head mechanism 200 has a groove for mounting the inflation / deflation port and a limiting cover for securing the inflation / deflation port within the groove. However, a separate structure for securing the inflation / deflation port (such as the aforementioned limiting cover) generally occupies a significant amount of space in the watch head mechanism 200, reducing its usable space and thus limiting the design and internal component layout of the watch head mechanism 200.

[0037] Based on this, the wearable device 10 provided in this application solves the above-mentioned technical problems by reusing the connecting component 120. That is, the watch head mechanism 200 can not only be detachably connected to the watch band assembly 110 through the connecting component 120, but also inflate and deflate the watch band assembly 110 through the connecting component 120. Compared with the scheme of using two different structures to realize detachable connection and fixed inflation / deflation interface respectively, the watch head mechanism 200 in this embodiment can omit the structure used to fix the inflation / deflation interface of the watch band assembly 110, so as to increase the available space of the watch head mechanism 200 and reduce the limitations on the shape design and internal component layout of the watch head mechanism 200 due to insufficient space.

[0038] All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.

[0039] Please combine Figure 2 See Figures 3 to 5 , Figure 3 yes Figure 2 A schematic diagram of the connection structure between the middle part of the watch strap 111 and the connecting component 120. Figure 4 yes Figure 2 A partial structural diagram of the central airbag 112. Figure 5 yes Figure 1 A schematic diagram of the cross-sectional structure of the wearable device 10 along line V-V.

[0040] The watch strap assembly 110 is connected to the connecting assembly 120 and can expand or contract under the control of the watch head mechanism 200. For example... Figures 2 to 3 As shown, the watch band assembly 110 includes a watch band 111 and an air bladder 112. The watch band 111 is connected to a connecting assembly 120 and can be detachably connected to a watch head mechanism 200 via the connecting assembly 120. The watch band 111 can be used to form a wearing space for the user in conjunction with the watch head mechanism 200. The air bladder 112 is disposed on the watch band 111 and connected to the connecting assembly 120. The air bladder 112 is also in communication with the connecting assembly 120, allowing the watch head mechanism 200 to inflate and deflate the air bladder 112 via the connecting assembly 120 to control the expansion or contraction of the air bladder, thereby cooperating with the watch head mechanism 200 to measure the user's blood pressure. Of course, in addition to blood pressure measurement, the air bladder 112 can also cooperate with the watch head mechanism 200 to achieve other measurement functions (such as heart rate measurement), which is not limited in this embodiment.

[0041] For example, the end of the watch strap 111 is connected to the connecting component 120, and the connecting component 120 is preferably embedded in the end of the watch strap 111. This enhances the connection between the watch strap 111 and the connecting component 120 while also concealing the connecting component 120, thereby improving the aesthetic appearance of the watch strap mechanism 100. Simultaneously, a portion of the structure of the connecting component 120 can protrude from the watch strap 111 to facilitate a detachable connection with the watch head mechanism 200. Furthermore, the side of the watch strap 111 within the wearing space can also be used to connect to the airbag 112, allowing the airbag 112 to conform to the user's wrist and thus cooperate with the watch head mechanism 200 to measure the user's blood pressure. For example, the side of the watch strap 111 within the wearing space has a connecting hole 1111, and the airbag 112 has a protrusion 1121 inserted into the connecting hole 1111 and press-fitted with the watch strap 111. Figure 4 (As shown), this allows for a detachable connection between the watch strap 111 and the airbag 112 (the positions of the connecting hole 1111 and the protrusion 1121 can also be interchanged). Alternatively, a Velcro closure can be provided on one side of the watch strap 111 within the wearing space, and this Velcro closure can be used for detachable connection with the airbag 112. In this embodiment, the material of the watch strap 111 can be TPU (Thermoplastic Urethane), knitted material, or fluororubber. Of course, the material of the watch strap 111 is not limited to these, and this embodiment does not list them all.

[0042] Optionally, the connecting component 120 can be embedded in the end of the watch strap 111, or it can be connected to the end of the watch strap 111 in other ways, as long as it can ensure that the watch strap 111 and the connecting component 120 have sufficient connection strength, and that the connecting component 120 can cooperate with the watch head mechanism 200. This embodiment is not limited in this respect. At the same time, in addition to being detachably connected to the airbag 112, the watch strap 111 can also be fixedly connected to the airbag 112, so that the watch strap 111 and the airbag 112 are not detachable, as long as it can ensure that the airbag 112 can communicate with the connecting component 120. This embodiment is not limited in this respect either.

[0043] Airbag 112 is located on one side of the watch strap 111 within the wearing space, and airbag 112 is also connected to and communicates with connecting component 120. For example... Figures 4 to 5As shown, the airbag 112 may include an airbag body 1122 and an air nozzle 1123. The airbag body 1122 is located on one side of the watch strap 111 within the wearing space and is connected to the watch strap 111. The airbag body 1122 may have the aforementioned protrusion 1121 on the side facing the watch strap 111. The air nozzle 1123 is located at the end of the airbag body 1122 on the side facing the watch strap 111, and is also connected to the interior of the airbag body 1122. Simultaneously, the air nozzle 1123 can also be connected to the connecting assembly 120, connecting the airbag body 1122 and the connecting assembly 120, allowing the watch head mechanism 200 to inflate or deflate the airbag body 1122 via the connecting assembly 120, thereby achieving the expansion or contraction of the airbag body 1122. In this embodiment, the air nozzle 1123 is preferably inserted into the connecting component 120 to communicate with the connecting component 120.

[0044] Optionally, to improve the airtightness of the airbag body 1122, the airbag body 1122 and the air nozzle 1123 can be fixed by heat pressing to improve the tightness of the connection between the airbag body 1122 and the air nozzle 1123. Of course, other connection methods can also be used for the airbag body 1122 and the air nozzle 1123, and this embodiment does not limit this.

[0045] Optionally, to reduce the probability of air leakage at the connection between the nozzle 1123 and the connecting assembly 120, the airbag 112 may also be provided with a sealing ring 1124 surrounding the nozzle 1123. When the nozzle 1123 is inserted into the connecting assembly 120, the sealing ring 1124 can abut against both the nozzle 1123 and the connecting assembly 120 to fill the gap between them, thereby reducing the probability of air leakage at the connection between the nozzle 1123 and the connecting assembly 120. In this embodiment, the sealing ring 1124 may be made of elastic materials such as silicone, rubber, and soft plastic, so that the sealing ring 1124 can abut against both the nozzle 1123 and the connecting assembly 120. Optionally, in addition to the sealing ring 1124, adhesive may also be applied to the connection between the nozzle 1123 and the connecting assembly 120 for sealing.

[0046] Furthermore, there can be two airbags 112, namely a first airbag 112a and a second airbag 112b. The first airbag 112a can be located on the side of the watch strap 111 within the wearing space, and the second airbag 112b can be located on the side of the first airbag 112a away from the watch strap 111. The first airbag 112a and the second airbag 112b are independent and can expand or contract under the control of the watch head mechanism 200. Meanwhile, when the user wears the wearable device 10, the first airbag 112a can cover most of the user's wrist area, so that it can expand extensively after inflation, allowing the first airbag 112a and the second airbag 112b to fit snugly against the user's wrist. The second airbag 112b can cover only the area where the radial artery is located in the user's wrist, so that it can expand slightly after inflation to compress and block the artery in the user's wrist. This, in conjunction with the meter mechanism 200, measures data such as the user's pulse pressure wave (single-point precise measurement), ultimately realizing the blood pressure measurement function of the wearable device 10.

[0047] In some embodiments, the first airbag 112a and the second airbag 112b are not internally connected. The first airbag 112a or the second airbag 112b may be a single-layer airbag or a multi-layer airbag.

[0048] In some embodiments, the first airbag 112a can be used for blood pressure detection, for example, by detecting the air pressure value of the first airbag 112a to obtain relevant information for calculating blood pressure values.

[0049] In some embodiments, the second airbag 112b can be used to exert pressure; or, the second airbag 112b can be used to fill. For example, the measuring part can be compressed by inflating the second airbag 112b, or the gap between it and the measuring part can be filled.

[0050] It should be noted that the embodiments, implementation methods and technical features of this application can be combined and substituted with each other without conflict.

[0051] Please combine Figure 5 See Figures 6 to 8 , Figure 6 yes Figure 2 A schematic diagram of the structure of the middle connecting component 120. Figure 7 yes Figure 6 A schematic diagram of the structure of the middle connector 121. Figure 8 yes Figure 6 A structural schematic diagram of the middle connector 121 from another perspective.

[0052] The connecting component 120 is connected to the end of the watch strap 111 and is detachably mounted on the watch head mechanism. The connecting component 120 also connects the airbag body 1122 and the watch head mechanism 200, allowing the watch head mechanism 200 to inflate and deflate the airbag body 1122 via the connecting component 120. Figure 5 As shown, the connecting assembly 120 has an air passage 1201. When the connecting assembly 120 is detachably connected to the meter head mechanism 200, the air passage 1201 can simultaneously connect the airbag body 1122 and the meter head mechanism 200, allowing the meter head mechanism 200 to inflate or deflate the airbag body 1122 through the air passage 1201, thereby expanding or contracting the airbag body 1122. With this configuration, the connecting assembly 120 can fix the connection between the air passage 1201 and the meter head mechanism 200 through its detachable connection, allowing the meter head mechanism 200 to omit the structure required to fix the air passage 1201, thus increasing the available space in the meter head mechanism 200 and reducing the limitations imposed on the meter head mechanism 200's shape design and internal component layout due to insufficient space. The structure of the connecting assembly 120 will be described in detail below.

[0053] like Figures 5 to 8 As shown, the connecting assembly 120 includes a connector 121 and a sealing cap 122. The connector 121 is also embedded within the end of the watch strap 111, and a portion of the connector 121 protrudes beyond the watch strap 111, allowing it to be inserted into the watch head mechanism 200 for detachable connection. The connector 121 may also have the aforementioned air passage 1201, and when the connector 121 is inserted into the watch head mechanism 200, a portion of the air passage 1201 can also be inserted into the watch head mechanism 200 simultaneously, with the insertion direction of the connector 121 parallel to the insertion direction of the air passage 1201. A sealing cap 122 is disposed on the connector 121, and the sealing cap 122 is used to seal the opening left on the connector 121 due to the formation of the air passage 1201 during processing. The sealing cap 122 is embedded in the end of the watch strap 111. The connector 121 and the sealing cap 122 are preferably made of rigid plastic to provide structural strength to the connecting assembly 120 and to help reduce the weight of the connecting assembly 120. Of course, the connection method between the connector 121 and the watch strap 111, as well as the materials selected for the connector 121 and the sealing cap 122, can be adjusted according to design requirements; this embodiment does not limit this.

[0054] Optionally, besides the connector 121 being inserted into the meter head mechanism 200, the connector 121 can also be inserted into the meter head mechanism 200 for detachable connection. Similarly, besides the air passage 1201 being inserted into the meter head mechanism 200, the air passage 1201 can also be inserted into the meter head mechanism 200 for communication. The following explanation uses the example of the connector 121 being inserted into the meter head mechanism 200, with the air passage 1201 also being inserted into the meter head mechanism 200 simultaneously with the connector 121. It is understood that the connector 121 can be inserted into the meter head mechanism 200 from the side; for example, the side of the meter head mechanism 200 may have an opening for partial or complete insertion of the connector 121.

[0055] For example, the connector 121 can be the end link of the watch strap 111, and the connector 121 includes: a main body 1211, a conductive part 1212, a protrusion 1213, and a buckle part 1214. The main body 1211 can be embedded in the end of the watch strap 111 to achieve connection between the connector 121 and the watch strap 111. The conductive part 1212 is connected to the main body 1211 and protrudes from the watch strap 111, and the end of the conductive part 1212 away from the main body 1211 can also be inserted into the watch head mechanism 200. The protrusion 1213 is connected to the main body 1211 and passes through the watch strap 111. When the watch strap 111 and the watch head mechanism 200 cooperate to form a wearing space, the protrusion 1213 can also be exposed on the side of the watch strap 111 facing the wearing space for the air nozzle 1123 to be inserted. The buckle portion 1214 is connected to the side of the main body portion 1211 where the guide portion 1212 is provided, and protrudes from the end of the watch strap 111. The buckle portion 1214 can also be inserted into the watch head mechanism 200 for detachable connection. In this embodiment, the guide portion 1212 can be inserted into the watch head mechanism 200 simultaneously with the buckle portion 1214, and the insertion direction of the guide portion 1212 is parallel to the insertion direction of the buckle portion 1214. The main body portion 1211, the guide portion 1212, the protrusion 1213, and the sealing cover 122 can together form the aforementioned air passage 1201, so that the air passage 1201 can connect the airbag body 1122 and the watch head mechanism 200.

[0056] The main body 1211 may include a first side 1211a, a second side 1211b, and a third side 1211c. The first side 1211a connects the buckle 1214 and the guide 1212, and when the buckle 1214 is detachably connected to the watch head mechanism 200, the first side 1211a can also be positioned opposite to the watch head mechanism 200. The second side 1211b and the third side 1211c are both connected to the first side 1211a and positioned opposite each other. The second side 1211b is also positioned near the side of the watch strap 111 facing the wearing space and connects to the protrusion 1213, so that the protrusion 1213 is exposed on the side of the watch strap 111 facing the wearing space. The third side 1211c allows the processing part to process the main body 1211, and the third side 1211c may have an opening left due to the formation of the air passage 1201 during processing. The sealing cover 122 is provided on the third side 1211c and seals the opening left due to the formation of the air passage 1201 during processing.

[0057] The terms "first," "second," and "third" used in this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature.

[0058] The main body 1211 also has an air guiding space 1201a, and the inner wall of the air guiding space 1201a can be used to form the aforementioned air passage 1201 together with the guiding part 1212, the protrusion 1213 and the sealing cover 122. Figure 5 and Figures 7 to 8 As shown, the air guiding space 1201a can be connected to the through part 1212 on the first side 1211a, so as to be connected to the instrument head mechanism 200 through the through part 1212. At the same time, the air guiding space 1201a also has a first opening 1202a and a second opening 1202b formed on the second side 1211b and the third side 1211c, respectively. The first opening 1202a can be connected to the protrusion 1213 on the second side 1211b, so that the air guiding space 1201a can also be connected to the airbag body 1122 through the protrusion 1213 and the air nozzle 1123. The second opening 1202b is an opening left on the third side 1211c after the main body 1211 is machined to form the air guiding space 1201a, and the sealing cap 122 can be provided on the third side 1211c to seal the second opening 1202b. With the above configuration, the inner wall of the air guide space 1201a can be used together with the guide part 1212, the protrusion 1213 and the sealing cover 122 located on the side of the air guide space 1201a (hereinafter referred to as the sealing cover 122) to form the aforementioned air passage 1201.

[0059] Optionally, the first opening 1202a may not be limited to being located on the second side 1211b. For example, when the airbag body 1122 is located inside the watchband 111, the first opening 1202a may also be located on the third side 1211c, and the connecting end of the airbag body 1122 may extend to the third side 1211c to communicate with the air guiding space 1201a through the first opening 1202a. Of course, in addition to the third side 1211c, the first opening 1202a may also be located on any outer surface of the main body 1211, as long as the airbag body 1122 can communicate with the air guiding space 1201a through the first opening 1202a. This embodiment does not limit this.

[0060] Understandably, if the conductive part 1212 and the protrusion 1213 are connected by opening holes in the main body 1211 in their extending directions, the holes can only connect at the intersection in their extending directions. The area of ​​the main body 1211 corresponding to the intersection of the extending directions of the conductive part 1212 and the protrusion 1213 needs to have a sufficiently large thickness; otherwise, the holes opened by the conductive part 1212 and the protrusion 1213 in their extending directions will directly penetrate the main body 1211 and cannot connect within the main body 1211. Increasing the thickness of the main body 1211 will not only increase the weight of the connector 121 but also affect the thickness of the watch strap 111 (the main body 1211 is embedded in the watch strap 111), which is not conducive to the overall thin and light design of the watch strap mechanism 100.

[0061] Based on this, this embodiment, by creating an air-guiding space 1201a on the third side 1211c to connect the guiding portion 1212 and the protrusion 1213, can shorten the length of the holes created in the guiding portion 1212 and the protrusion 1213 in their extending direction, thereby reducing the required thickness of the main body 1211 at the connection point between the guiding portion 1212 and the protrusion 1213 (corresponding to the air-guiding space 1201a). Simultaneously, the design of the air-guiding space 1201a also facilitates subsequent processing of the air passage 1201's shape from the second opening 1202b. For example, the wall surface at the connection point between the air-guiding space 1201a and the guiding portion 1212 (the corner of the air passage 1201) can be polished from the second opening 1202b to grind sharp edges into curved surfaces, thereby improving the air-guiding effect of the air passage 1201.

[0062] Optionally, to prevent the sealing cap 122 from protruding on the third side 1211c due to blocking the second opening 1202b, a receiving groove 1203 can be provided on the third side 1211c, and the second opening 1202b can be formed on the bottom wall of the receiving groove 1203. The sealing cap 122 can be disposed within the receiving groove 1203 and block the second opening 1202b. The receiving groove 1203 can also absorb the thickness of the sealing cap 122 to prevent it from protruding on the third side 1211c. Simultaneously, the sealing cap 122 can be fixed in the receiving groove 1203 by adhesive application or spot welding to improve the connection strength and sealing performance between the sealing cap 122 and the main body 1211. In this embodiment, the shape of the sealing cap 122 can match the receiving groove 1203, and the size of the sealing cap 122 can be slightly smaller than the size of the receiving groove 1203 to facilitate installation of the sealing cap 122.

[0063] Optionally, the sealing cap 122 may also be spaced apart from the side wall of the receiving groove 1203, so that there is a gap between the sealing cap 122 and the side wall of the receiving groove 1203. With this configuration, when the watch strap 111 and the connector 121 are subjected to in-mold injection molding, the watch strap 111 can also fill the gap between the sealing cap 122 and the side wall of the receiving groove 1203, so as to further improve the bonding strength of the watch strap 111, the connector 121 and the sealing cap 122.

[0064] Optionally, the design of the sealing cap 122 can also be omitted. In this case, in order to form the aforementioned air guiding space 1201a without increasing the thickness of the main body 1211, the main body 1211 can also be designed as two independent structural components. The two independent structural components can be spliced ​​together to form a complete main body 1211, and can jointly enclose the air guiding space 1201a after splicing, thereby omitting the design of forming a second opening 1202b on the third side 1211c of the air guiding space 1201a. In addition, in order to improve the sealing performance of the air guiding space 1201a, the gap between the two spliced ​​structural components can be glued or filled with other airtight materials. In this embodiment, when the design of the sealing cap 122 is omitted, the inner wall of the air guiding space 1201a can be used to form the aforementioned air passage 1201 together with the guiding part 1212 and the protrusion 1213.

[0065] Optionally, the first side 1211a may also be recessed towards the main body 1211, forming a clearance space 1204 for avoiding the meter head mechanism 200, and both the connecting part 1212 and the latching part 1214 may be located within the clearance space 1204. When the latching part 1214 and the connecting part 1212 are simultaneously inserted into the meter head mechanism 200, the clearance space 1204 can be used to avoid interference with the meter head mechanism 200, thereby ensuring that the latching part 1214 and the connecting part 1212 can be inserted into place.

[0066] Optionally, the main body 1211 can also be bent toward the side of the strap 111 closer to the wearing space, so that the main body 1211 can have an arc curvature toward the wearing space, so that the end of the strap 111 in which the main body 1211 is embedded can be bent, thereby forming a wearing space together with the watch head mechanism 200. At the same time, the sealing cover 122 can also match the third side 1211c of the main body 1211. That is, the surface of the sealing cover 122 exposed on the third side 1211c can also be a curved surface, thereby avoiding the sealing cover 122 forming a protrusion on the third side 1211c. In addition, the thickness of the main body 1211 gradually decreases in the direction away from the conduction portion 1212, so that the thickness of the strap 111 can also gradually decrease in the direction away from the conduction portion 1212, which is beneficial to the thinner design of the strap 111. Of course, the shape of the main body 1211 is not limited, and the specific shape of the main body 1211 can be adapted to design requirements. This embodiment does not limit this.

[0067] Optionally, the main body 1211 can also be bent in the direction of the third side 1211c near the second side 1211b, so that the main body 1211 as a whole can have a certain curvature to match the shape of the user's wrist, thereby reducing the gap between the user's wrist and the end of the watch strap 111 connected to the main body 1211, which is beneficial to improving the tightness of the fit between the airbag body 1122 and the user's wrist after inflation.

[0068] Furthermore, the connecting part 1212 is connected to the first side 1211a and can be inserted into the meter mechanism 200 simultaneously when the latching part 1214 is inserted into the meter mechanism 200. The connecting part 1212 also has an air outlet 1201b that connects the air guiding space 1201a and the meter mechanism 200. The inner walls of the air guiding space 1201a and the air outlet 1201b can be used to form the aforementioned air passage 1201 together with the protrusion 1213 and the sealing cover 122. The axial direction of the air outlet 1201b can be parallel to the insertion direction of the connecting part 1212, and the air outlet 1201b can penetrate the connecting part 1212 on opposite sides near and away from the main body 1211, and simultaneously penetrate the first side 1211a of the main body 1211 to communicate with the air guiding space 1201a. With this configuration, the air outlet 1201b can connect the air guide space 1201a and the meter mechanism 200 after the meter head mechanism 200 is inserted into the end of the guide portion 1212 away from the main body portion 1211.

[0069] Optionally, to reduce the probability of air leakage at the connection between the conductive part 1212 and the meter mechanism 200, the connecting assembly 120 may also be provided with a sealing element 123 sleeved on the conductive part 1212. Figure 5 and Figure 6 (As shown), when the conductive part 1212 is inserted into the meter mechanism 200, the sealing member 123 can abut against both the conductive part 1212 and the meter mechanism 200 to fill the gap between them, thereby reducing the probability of air leakage at the connection between the conductive part 1212 and the meter mechanism 200. In this embodiment, the sealing member 123 can also be made of elastic materials such as silicone, rubber, and soft plastic, so that the sealing member 123 can abut against both the conductive part 1212 and the meter mechanism 200.

[0070] Alternatively, the vent 1201b may not be limited to the side of the conductor 1212 away from the main body 1211, and the vent 1201b may also penetrate the periphery of the conductor 1212, and the watch strap mechanism 100 may also communicate with the vent 1201b from the periphery of the conductor 1212.

[0071] Optionally, the design of the connecting part 1212 can be omitted. In this case, in order to achieve communication between the air guiding space 1201a and the meter mechanism 200, a third opening can be formed on the first side 1211a of the air guiding space 1201a. The meter mechanism 200 can be provided with a structure similar to the connecting part 1212, and the third opening can avoid the meter mechanism 200, so that the meter mechanism 200 can be inserted into the air guiding space 1201a through the third opening to achieve communication between the meter mechanism 200 and the air guiding space 1201a. In this embodiment, when the design of the connecting part 1212 is omitted, the inner wall of the air guiding space 1201a can be used to form the aforementioned air passage 1201 together with the protrusion 1213 and the sealing cover 122.

[0072] Furthermore, the protrusion 1213 is connected to the second side 1211b and passes through the watch strap 111, and the protrusion 1213 is also exposed on the side of the watch strap 111 facing the wearing space. At the same time, the protrusion 1213 can also be arranged around the first opening 1202a and surround a receiving hole 1201c that connects the air guide space 1201a and the air nozzle 1123. The inner walls of the air guide space 1201a, the air outlet 1201b and the receiving hole 1201c can be used together with the sealing cover 122 to form the aforementioned air passage 1201. Since the protrusion 1213 passes through the watch strap 111, the receiving hole 1201c can be exposed on the side of the watch strap 111 facing the wearing space for the air nozzle 1123 to be inserted. The sealing ring 1124 can abut against the inner walls of the air nozzle 1123 and the receiving hole 1201c respectively to improve the sealing performance of the air nozzle 1123 when inserted into the protrusion 1213. In this embodiment, the air nozzle 1123 and the protrusion 1213 can be detachably connected or non-detachably connected; this embodiment does not limit this.

[0073] Optionally, the aperture of the receiving hole 1201c can be larger than the aperture of the first opening 1202a, so that the air nozzle 1123 can still contact the second side 1211b after being inserted into the receiving hole 1201c, so as to limit the insertion distance of the air nozzle 1123 by using the second side 1211b.

[0074] Optionally, when the airbag 112 has a rigid structure on the airbag body 1122 into which the protrusion 1213 can be inserted, the protrusion 1213 can also be inserted into the rigid structure to connect the air guiding space 1201a and the airbag body 1122 via the receiving hole 1201c. Alternatively, the protrusion 1213 can also be directly inserted into the airbag body 1122 and fixedly connected to the airbag body 1122, so that the airbag body 1122 and the connector 121 are a connected integral structure.

[0075] Optionally, the protrusion 1213 can be omitted. In this case, to achieve communication between the air guide space 1201a and the instrument head mechanism 200, the nozzle 1123 can be directly inserted into the air guide space 1201a through the first opening 1202a to achieve communication between the airbag body 1122 and the air guide space 1201a. In this embodiment, when the protrusion 1213 is omitted, the inner wall of the air guide space 1201a can be used together with the inner wall of the air outlet 1201b and the sealing cap 122 to form the aforementioned air passage 1201.

[0076] Optionally, the design of the connecting portion 1212 and the protrusion 1213 can also be omitted. In this case, the inner wall of the air guiding space 1201a and the sealing cover 122 can together form the aforementioned air passage 1201.

[0077] Furthermore, when there are two airbags 112, there can also be two airways 1201, which are respectively connected to the air nozzles 1123 of the two airbags 112. Figures 5 to 8 As shown, the main body 1211 may have two independent air-guiding spaces 1201a. There may also be two connecting parts 1212, each communicating with one of the two air-guiding spaces 1201a, and each connecting part 1212 is also used to insert the meter mechanism 200. There may also be two protrusions 1213, each communicating with one of the two air-guiding spaces 1201a, and each protrusion 1213 is also connected to the air nozzles 1123 of the two airbags 112. There may also be two sealing caps 122, and each sealing cap 122 is used to block the two second openings 1202b formed on the third side 1211c of the two air-guiding spaces 1201a. In this embodiment, the two air-guiding spaces 1201a, the two connecting parts 1212, the two protrusions 1213, and the two sealing caps 122 may be symmetrically arranged about the length direction L. The cooperation relationship between the individual air guiding space 1201a, the guiding part 1212, the protrusion 1213, and the sealing cover 122 can be referred to the aforementioned embodiments, and will not be repeated here.

[0078] Furthermore, the latching part 1214 is connected to the first side 1211a and is used to insert into the meter head mechanism 200 for detachable connection with the meter head mechanism 200. Figures 7 to 8As shown, the latching part 1214 may have a latching groove 12141. When the latching part 1214 is inserted into the meter head mechanism 200, the mating structure of the meter head mechanism 200 can enter the latching groove 12141 and engage with the latching part 1214 in the direction of exiting the meter head mechanism 200, thereby achieving a fixed connection between the latching part 1214 and the meter head mechanism 200. Simultaneously, the mating structure of the meter head mechanism 200 can also exit the latching groove 12141 to release the engagement with the latching part 1214, allowing the latching part 1214 to be detached from the meter head mechanism 200, thus achieving a detachable connection between the latching part 1214 and the meter head mechanism 200. In this embodiment, when there are two conductive parts 1212, the latching part 1214 is also located between the two spaced-apart conductive parts 1212.

[0079] Optionally, in addition to being detachably connected to the meter head mechanism 200, the latching part 1214 may also have the aforementioned vent 1201b, so as to simultaneously connect with the meter head mechanism 200 when inserted. That is, the latching part 1214 can simultaneously serve the functions of detachably connecting with the meter head mechanism 200 and connecting with the meter head mechanism 200. In this embodiment, when the latching part 1214 has the vent 1201b, the design of the guide part 1212 can be omitted, and the way the vent 1201b is opened on the latching part 1214 can be the same as or similar to the aforementioned embodiment, and will not be described in detail here.

[0080] Optionally, there can be two latching parts 1214, which are spaced apart between the two conducting parts 1212 and respectively inserted into the meter head mechanism 200 for detachable connection, thereby improving the connection stability between the connecting component 120 and the meter head mechanism 200. The two latching parts 1214 can also be symmetrically arranged to improve the consistency of their insertion into the meter head mechanism 200. Simultaneously, the slots 12141 on both latching parts 1214 can penetrate the sides of the two latching parts 1214 closest to each other, forming corresponding clearance positions between the two latching parts 1214, thus facilitating the entry of the mating structure of the meter head mechanism 200 into the slots 12141. Of course, the specific design of the slots 12141 can be adaptively adjusted according to requirements, as long as the mating structure of the meter head mechanism 200 can enter the slots 12141 and engage with the latching parts 1214; this embodiment does not limit this.

[0081] It is understood that, in addition to the watch strap mechanism 100 and the watch head mechanism 200 being connected in the aforementioned detachable manner, the watch strap mechanism 100 and the watch head mechanism 200 can also be connected in a non-detachable manner, as long as the watch strap mechanism 100 can be connected to the watch head mechanism 200 simultaneously when it is assembled onto the watch head mechanism 200. This embodiment does not limit this.

[0082] Please combine Figure 5 See Figures 9 to 12 , Figure 9 yes Figure 1 A structural diagram of the central header mechanism 200. Figure 10 yes Figure 9 A schematic diagram of the connection structure between the middle housing assembly 210 and the air pump assembly 220. Figure 11 yes Figure 10 A schematic diagram of the partial cross-sectional structure of the middle housing assembly 210 and the air pump assembly 220 along line VI-VI. Figure 12 yes Figure 10 A schematic diagram of the partial cross-sectional structure of the middle housing assembly 210 and the air pump assembly 220 along V-V.

[0083] The meter head mechanism 200 is detachably connected to the latching part 1214, and can simultaneously communicate with the air passage 1201 when detachably connected to the latching part 1214. The meter head mechanism 200 can inflate and deflate the airbag 112 through the air passage 1201, causing the airbag 112 to expand or contract. Figures 9 to 12 As shown, the meter head mechanism 200 may include a housing assembly 210, an air pump assembly 220, and an unlocking assembly 240. The housing assembly 210 encloses a mounting space 201 for installing the air pump assembly 220, and a latching part 1214 can be inserted into the side of the housing assembly 210 facing away from the mounting space 201. The housing assembly 210 also has an air guide hole 202 connecting the air pump assembly 220 and the air passage 1201, allowing the air pump assembly 220 to inflate and deflate the airbag 112 through the air guide hole 202 and the air passage 1201. Furthermore, the housing assembly 210 also has a vent hole 203 connecting the air pump assembly 220 and the air guide hole 202, allowing the airbag 112 to deflate into the air pump assembly 220 through the vent hole 203. The unlocking component 240 is slidably disposed on the housing component 210 and can engage with the latching part 1214 inserted into the housing component 210. It can also release the engagement with the latching part 1214 under user pressure, thereby realizing the detachable connection between the latching part 1214 and the housing component 210.

[0084] For example, housing assembly 210 may include: a border 211. (e.g.) Figures 10 to 12The frame 211 can enclose an installation space 201 for accommodating the air pump assembly 220. The frame 211 has a top surface 2111 and a bottom surface 2112 facing away from each other, and a side surface 2113 surrounding the top surface 2111 and the bottom surface 2112. The side surface 2113 has an air guide hole 202 communicating with the air pump assembly 220 and the air passage 1201, and also has a slot 2001 for inserting the latching part 1214. This slot 2001 can accommodate a portion of the unlocking assembly 240, allowing the latching part 1214 to be detachably connected to the side surface 2113 of the frame 211 via the unlocking assembly 240. Simultaneously, when the latching part 1214 is inserted into the slot 2001, the conduction portion 1212 of the strap mechanism 100... Figure 5 (As shown) It can also be inserted into the air guide hole 202 simultaneously from the side 2113 to realize the connection between the air guide hole 202 and the air passage 1201.

[0085] Furthermore, the bottom surface 2112 has a vent 203 connecting the air guide hole 202 and the air pump assembly 220, and the bottom surface 2112 also has a sliding groove 2002 communicating with the slot 2001, and the unlocking component 240 is slidably disposed in the sliding groove 2002. To enable the vent 203 to communicate with the air pump assembly 220, the frame 211 also has a connecting post 2114 on the bottom surface 2112, and this connecting post 2114 can be inserted into the air pump assembly 220. Simultaneously, the vent 203 can penetrate the side of the connecting post 2114 away from the bottom surface 2112 to connect the air pump assembly 220 and the air guide hole 202. In addition, the inner walls of the air guide hole 202 and the inner walls of the vent 203 can together form an external air passage 2201 communicating with the air pump assembly 220. Of course, in some embodiments, the external air passage 2201 may also include the inner walls of other holes or grooves for guiding air, other than the inner walls of the air guide hole 202 and the air vent 203. It is only necessary that the external air passage 2201 can be connected to the air pump assembly 220 through the air guide hole 202 and the air vent 203 respectively to form a redundant air passage design. This embodiment will not list them all here.

[0086] Optionally, the mounting space 201 can be used not only to install the air pump assembly 220, but also to install other functional components required by the meter mechanism 200, such as batteries, speakers, and microphones. Simultaneously, when there are two latching parts 1214, there are also two slots 2001, allowing each latching part 1214 to be inserted. Both slots 2001 can accommodate a portion of the unlocking assembly 240, enabling the two latching parts 1214 to still cooperate with the unlocking assembly 240, thus achieving a detachable connection between the latching parts 1214 and the frame 211.

[0087] Furthermore, when there are two air passages 1201, there can also be two air guide holes 202, for each of the two air passages 1201 to be inserted into, and two slots 2001 can be arranged between the two air guide holes 202. Correspondingly, there can also be two vent holes 203, and the two vent holes 203 can be connected to the two air guide holes 202 respectively, so as to form two independent external air passages 2201. In this embodiment, the two external air passages 2201 can be the first external air passage 2201a and the second external air passage 2201b, respectively, to communicate with the two airbags 112 of the strap mechanism 100, that is, the first airbag 112a and the second airbag 112b.

[0088] Optionally, the mounting space 201 may extend through the top surface 2111 and bottom surface 2112 of the frame 211 to facilitate the installation of functional devices within the mounting space 201. Additionally, the housing assembly 210 may further include a rear cover 212. Figure 9 (As shown), and the back cover 212 can be placed on the bottom surface 2112 of the frame 211, and cover and close the mounting space 201 to protect the functional devices located within the mounting space 201. In addition, the meter head mechanism 200 may also include: a display component 250 (… Figure 9 (as shown), and the display component 250 can be placed on the top surface 2111 of the frame 211 to realize the display function of the meter head mechanism 200 while cooperating with the back cover 212 to close the installation space 201.

[0089] Optionally, the housing assembly 210 may further include a sealing ring 213. For example... Figure 11 As shown, the sealing ring 213 is located between the frame 211 and the air pump assembly 220, and abuts against both the frame 211 and the air pump assembly 220. The sealing ring 213, together with the frame 211 and the air pump assembly 220, forms a sealed space, which connects the air vent 202 and the air pump assembly 220. For example, the air inlet formed on the side of the frame 211 within the mounting space 201 can be located within the sealed space, and the air outlet of the air pump assembly 220 can also be located within the sealed space, allowing the sealed space to connect the air vent 202 and the air pump assembly 220. Furthermore, the sealing ring 213 can be made of elastic materials such as silicone, rubber, or soft plastic, allowing it to abut against both the frame 211 and the air pump assembly 220.

[0090] By providing a sealing ring 213 between the frame 211 and the air pump assembly 220, and by forming a sealed space together with the frame 211 and the air pump assembly 220, the air guide hole 202 and the air pump assembly 220 can be connected through the sealed space. This reduces the restrictions on the placement of the air pump assembly 220 within the installation space 201 and the placement of the air guide hole 202 on the frame 211. In other words, if the sealing ring 213 is omitted, the air outlet of the air pump assembly 220 and the air inlet of the air guide hole 202 need to be aligned to ensure their connection, which would undoubtedly restrict the positions of the air pump assembly 220 and the air guide hole 202. Based on this, this embodiment utilizes a sealed space to connect the air pump assembly 220 and the air guide hole 202, so that the air outlet of the air pump assembly 220 and the air inlet of the air guide hole 202 are not limited to the arrangement of relative alignment (they can also be staggered), which is beneficial to improving the flexibility of the layout of various structures on the meter mechanism 200.

[0091] Optionally, the design of the sealing ring 213 can be omitted when the air outlet of the air pump assembly 220 and the air inlet of the air guide hole 202 are aligned. Of course, even if the air outlet of the air pump assembly 220 and the air inlet of the air guide hole 202 are aligned, the design of the sealing ring 213 can be retained to fill the gap between the frame 211 and the air pump assembly 220, thereby improving the sealing performance of the air pump assembly 220 and the frame 211 after assembly.

[0092] Optionally, considering that the vent 202 will be directly exposed to the external environment after the strap mechanism 100 is detached from the watch head mechanism 200, the housing assembly 210 may also include a dustproof mesh 214. The dustproof mesh 214 is disposed between the sealing ring 213 and the frame 211, and abuts against both the sealing ring 213 and the frame 211. The dustproof mesh 214 can also cover the sealed space formed by the sealing ring 213 and the air inlet of the vent 202, thereby blocking dust from entering the sealed space through the vent 202 and preventing dust from entering the air pump assembly 220.

[0093] Optionally, the dustproof net 214 can be disposed between the sealing ring 213 and the frame 211, or between the sealing ring 213 and the air pump assembly 220, and can abut against the sealing ring 213 and the air pump assembly 220 respectively. The dustproof net 214 can also cover the sealed space formed by the sealing ring 213 and the air outlet of the air pump assembly 220 to block dust from entering the air pump assembly 220 from the air guide hole 202 and the sealed space. Alternatively, dustproof nets 214 can be provided between the sealing ring 213 and the air pump assembly 220, and between the sealing ring 213 and the frame 211, to improve the dustproof performance of the meter mechanism 200. This embodiment does not limit this.

[0094] Please combine Figures 11 to 12 See Figures 13 to 16 , Figure 13 yes Figure 10 Schematic diagram of the structure of the air pump assembly 220. Figure 14 yes Figure 13 Exploded view of the air pump assembly 220. Figure 15 yes Figure 13 A schematic diagram of a partial cross-sectional structure of the medium-pressure air pump assembly 220 along line IV-IV. Figure 16 yes Figure 13 A schematic diagram of a partial cross-sectional structure of the air pump assembly 220 along line V-V.

[0095] The air pump assembly 220 can be located within the installation space 201 and can be connected to the air guide hole 202 and the air vent 203 respectively. For example... Figures 13 to 14 As shown, the air pump assembly 220 may include: a mounting bracket 221, an air pump 222, a first main control valve 223, a second main control valve 224, and a secondary control valve 225. The mounting bracket 221 can be disposed within the installation space 201, forming a cavity 2202. The air pump 222 is mounted on the mounting bracket 221 and communicates with the cavity 2202, and the air pump 222 can charge and depress the cavity 2202. Both the first main control valve 223 and the second main control valve 224 are mounted on the mounting bracket 221. The first main control valve 223 connects the cavity 2202 to a first external air passage 2201a, and the second main control valve 224 connects the cavity 2202 to a second external air passage 2201b. The secondary control valve 225 is mounted on the mounting bracket 221 and connects to both the first and second external air passages 2201a and 2201b.

[0096] This configuration allows the secondary control valve 225 to connect to independent first external air passages 2201a and 2201b, enabling the first main control valve 223 (connected to the first external air passage 2201a) and the second main control valve 224 (connected to the second external air passage 2201b) to serve as backup valves for each other. Specifically, when the first main control valve 223 malfunctions, the secondary control valve 225 can connect the first and second external air passages 2201a and 2201b, guiding the gas from the first external air passage 2201a to the second external air passage 2201b, and then releasing it into the cavity 2202 via the second main control valve 224. This reduces the safety risk caused by the inability to release gas due to a malfunction of the first main control valve 223, thereby improving the operational safety of the air pump assembly 220.

[0097] For example, the mounting bracket 221 can be disposed within the mounting space 201 and form a cavity 2202, and the mounting bracket 221 can be used to install various structural components required for the air pump assembly 220. Figure 11 , Figure 14as well as Figure 15 As shown, the mounting bracket 221 may include a top side 2211, a bottom side 2212, and a peripheral side 2213. The top side 2211 and the bottom side 2212 may be arranged opposite to each other, while the peripheral side 2213 may be arranged around the top side 2211 and the bottom side 2212, and opposite to the side 2113 of the frame 211. The air pump 222 may be located on the top side 2211, and the mounting bracket 221 has a first through hole 2203 on the top side 2211 connecting the cavity 2202 and the air pump 222. The first main control valve 223 and the second main control valve 224 may be located on the peripheral side 2213, facing the air guide hole 202. The mounting bracket 221 has two second through holes 2204 on the peripheral side 2213 connecting the cavity 2202, and the first main control valve 223 and the second main control valve 224 may respectively connect to the cavity 2202 through the two second through holes 2204. The secondary control valve 225 can be located on the bottom side 2212, and the mounting bracket 221 also has a third through hole 2205 on the bottom side 2212 that connects the cavity 2202 and the secondary control valve 225.

[0098] Specifically, the mounting bracket 221 may include a top cover 221a and a bottom shell 221b. The top cover 221a is fitted onto the bottom shell 221b and together with the bottom shell 221b forms a cavity 2202. The side of the top cover 221a facing away from the bottom shell 221b is the top side 2211, and the side of the bottom shell 221b facing away from the top cover 221a is the bottom side 2212. The bottom shell 221b also has a peripheral side 2213 surrounding the top side 2211 and the bottom side 2212. The top cover 221a has a first through hole 2203 on the top side 2211, while the bottom shell 221b has a second through hole 2204 on the peripheral side 2213 and a third through hole 2205 on the bottom side 2212. Of course, in some embodiments, the specific structure of the mounting bracket 221 can also be adapted to design requirements, and is not limited to the scheme shown in the above embodiments. This embodiment does not limit this.

[0099] In some embodiments, the mounting bracket 221 may also be part of the housing assembly 210, so that the housing assembly 210 may have a cavity 2202, and the air pump assembly 220 may not include the mounting bracket 221. It is sufficient that the first main control valve 223, the second main control valve 224 and the auxiliary control valve 225 are assembled onto the housing assembly 210 and can communicate with the cavity 2202. This embodiment does not limit this.

[0100] The air pump 222 can be mounted on the top side 2211, and the air pump 222 can not only inflate the cavity 2202. For example... Figure 15As shown, the air pump 222 is mounted on the top side 2211 and covers the first through hole 2203, and the air outlet of the air pump 222 can be positioned opposite to the first through hole 2203. The air pump 222 can not only inflate the cavity 2202 through the first through hole 2203, but also deflate the cavity 2202 through the first through hole 2203. That is, the air pump 222 can be a deflation pump, allowing it to be used not only for inflation but also for deflation, to expel the gas that has been released from the airbag body 1122 into the cavity 2202. It is understood that the placement of the air pump 222 on the mounting bracket 221 can be adapted to design requirements, and is not limited to being positioned on the top side 2211 of the mounting bracket 221; this embodiment does not impose such a limitation.

[0101] The first main control valve 223 and the second main control valve 224 can be arranged relative to each other and spaced apart on the peripheral side 2213. The first main control valve 223 can be connected to a vent 202 (first external air passage 2201a) and a second through hole 2204 (cavity 2202), and the second main control valve 224 can be connected to another vent 202 (second external air passage 2201b) and another second through hole 2204 (cavity 2202). It is understood that the arrangement of the first main control valve 223 and the second main control valve 224 on the mounting bracket 221 can also be adaptively adjusted according to the position of the vent 202, and is not limited to being arranged on the peripheral side 2213 of the mounting bracket 221. This embodiment does not limit this arrangement.

[0102] The secondary control valve 225 can be located on the bottom side 2212, and the secondary control valve 225 can be connected to the third through hole 2205 and the vent hole 203 respectively to control the flow of gas between the cavity 2202 and the vent hole 203. Figure 12 , Figure 15 as well as Figure 16As shown, the secondary control valve 225 may include: a valve body 2251, a first conduit 2252, and a second conduit 2253. The valve body 2251 may be located on the bottom side 2212 and may be connected to the cavity 2202 through a third through hole 2205. The first conduit 2252 may connect the valve body 2251 to a connecting post 2114 and connect the valve body 2251 to a vent 203 (first external air passage 2201a). The second conduit 2253 may connect the valve body 2251 to another connecting post 2114 and connect the valve body 2251 to another vent 203 (second external air passage 2201b). Simultaneously, the first conduit 2252 and the second conduit 2253 may be located on opposite sides of the valve body 2251, so that the first conduit 2252 and the second conduit 2253 may be connected to the two connecting posts 2114 respectively. Of course, as the position of the connecting column 2114 changes, the first conduit 2252 and the second conduit 2253 may not be limited to the opposite sides of the valve body 2251. This embodiment does not limit this.

[0103] Furthermore, to achieve communication between the valve body 2251 and the cavity 2202, the secondary control valve 225 may further include a guide column 2254. The guide column 2254 is located on the side of the valve body 2251 facing the bottom 2212 and can pass through the third through hole 2205. Simultaneously, the end of the guide column 2254 away from the valve body 2251 can be located within the cavity 2202, and the guide column 2254 can also connect the valve body 2251 and the cavity 2202. For example, the guide column 2254 may have a hole connecting the cavity 2202 and the valve body 2251. Of course, in some embodiments, the design of the guide column 2254 may be omitted, and the valve body 2251 may be directly connected to the cavity 2202 through the third through hole 2205. Alternatively, the air guide column 2254 can also be located on the bottom side 2212 and inserted into the valve body 2251 to connect the valve body 2251 and the third through hole 2205. That is, there are multiple ways to connect the valve body 2251 and the cavity 2202, which will not be listed here in this embodiment.

[0104] Furthermore, when the valve body 2251 is energized, it can connect the cavity 2202 and the first conduit 2252, or connect the cavity 2202 and the second conduit 2253. When the valve body 2251 is de-energized, it can simultaneously connect the cavity 2202, the first conduit 2252, and the second conduit 2253. For example, the valve body 2251 may contain a movable seal. When the valve body 2251 is energized, the seal can move within it to block either the first conduit 2252 or the second conduit 2253. When the valve body 2251 is de-energized, the seal can reset without blocking either the first conduit 2252 or the second conduit 2253. It is understood that the above-described working principle of the valve body 2251 is merely illustrative, and the valve body 2251 may operate in ways not limited to the above scheme. This embodiment does not limit this aspect. It is understood that the arrangement position of the valve body 2251 on the mounting bracket 221 can be adapted to design requirements, and is not limited to being set on the bottom side 2212 of the mounting bracket 221. This embodiment does not limit this.

[0105] Furthermore, the structures of the first conduit 2252 and the second conduit 2253 can be the same or similar. The following explanation uses the example of the first conduit 2252 connecting the valve body 2251 and a connecting post 2114. Figure 12 As shown, one end of the first conduit 2252 can be sleeved on a connecting post 2114 to communicate with a vent 203 penetrating the connecting post 2114. The first conduit 2252 can also be press-fitted with the connecting post 2114 to improve the sealing performance of the connection between the first conduit 2252 and the connecting post 2114. Similarly, the other end of the first conduit 2252 can be connected to the valve body 2251 in the same or similar manner and communicate with the valve body 2251. That is, the valve body 2251 can also have a structure similar to the connecting post 2114 to mate with the other end of the first conduit 2252. In this embodiment, the first conduit 2252 can be a hollow flexible tube, making it flexible. This not only facilitates the press-fitting of the first conduit 2252 with the connecting post 2114 but also improves the layout flexibility of the first conduit 2252 within the installation space 201.

[0106] With the above configuration, the secondary control valve 225 can also serve as a backup valve for the first main control valve 223 and the second main control valve 224, and is connected to the vent 203 to form a redundant air path design. When the first main control valve 223 and / or the second main control valve 224 malfunction and cannot connect the vent 202 and the cavity 2202, the gas in the airbag 112 can be released into the cavity 2202 under the control of the secondary control valve 225, thereby reducing the risk of bursting caused by the airbag 112 failing to release gas in time, and thus improving the safety of the air pump assembly 220.

[0107] In some embodiments, the secondary control valve 225 may be used only to connect the first external air passage 2201a and the second external air passage 2201b, without connecting to the cavity 2202. This allows the first main control valve 223 and the second main control valve 224 to serve as backup valves for each other, forming a redundant air passage design. When the first main control valve 223 fails, the secondary control valve 225 can connect the first external air passage 2201a and the second external air passage 2201b, guiding the gas from the first external air passage 2201a to the second external air passage 2201b, and then releasing it into the cavity 2202 through the second main control valve 224. This reduces the safety risk caused by the inability to release gas due to a failure of the first main control valve 223, thereby improving the operational safety of the air pump assembly 220.

[0108] In some embodiments, the secondary control valve 225 can also connect to the external atmosphere (such as the installation space 201) and the first external air passage 2201a and the second external air passage 2201b, so that the secondary control valve 225 can not only serve as a backup valve for the first main control valve 223 and the second main control valve 224, but also directly discharge the gas from the first external air passage 2201a and the second external air passage 2201b to the external atmosphere without needing to release the gas through the air pump 222. For example, based on the scheme shown in the above embodiments, the secondary control valve 225 can also be supplemented with a movable sealing member, which can be used to open or close the opening of the secondary control valve 225 connecting to the external atmosphere. When the secondary control valve 225 is energized, the sealing member can block the first conduit 2252 or the second conduit 2253, and the sealing member can block the opening of the secondary control valve 225 connecting to the external atmosphere. When the secondary control valve 225 is de-energized, the sealing element may not block the first conduit 2252 and the second conduit 2253, nor may the sealing element block the opening of the secondary control valve 225 connecting to the external atmosphere, allowing the first external air passage 2201a and the second external air passage 2201b to communicate with the external atmosphere. It is understood that the specific structure of the aforementioned secondary control valve 225 is merely illustrative, and there are various other design options for the secondary control valve 225. For example, the secondary control valve 225 may also be equipped with two independent sealing elements to respectively block the first conduit 2252 and the second conduit 2253; this embodiment does not limit this approach.

[0109] In some embodiments, the secondary control valve 225 can also simultaneously connect to the cavity 2202, the first external air passage 2201a, the second external air passage 2201b, and the external atmosphere. This allows the secondary control valve 225 to serve not only as a backup valve for the first main control valve 223 and the second main control valve 224, but also as a backup valve for the air pump 222, so that when the air pump 222 malfunctions and cannot release air, the gas in the cavity 2202 can be released to the external atmosphere. The design of the secondary control valve 225 can be the same as or similar to the aforementioned structure of the secondary control valve 225 connecting to the external atmosphere and the first external air passage 2201a and the second external air passage 2201b; this will not be elaborated upon in this embodiment.

[0110] To release the gas inside cavity 2202 to the outside of cavity 2202, the air pump assembly 220 may further include a vent valve 226. For example... Figure 11 , Figure 14 as well as Figure 15 The vent valve 226 can be mounted on the mounting bracket 221 and can connect the cavity 2202 with the external atmosphere, so that the gas released into the cavity 2202 by the airbag 112 can also be released out of the cavity 2202 under the control of the vent valve 226. The air pump 222 with the venting function can be regarded as a backup valve for the vent valve 226. For example, the vent valve 226 can be mounted on the periphery 2213 of the mounting bracket 221, and the vent valve 226 can also be located between the first main control valve 223 and the second main control valve 224. The mounting bracket 221 (bottom shell 221b) has a fourth through hole 2206 on the periphery 2213 that connects the cavity 2202 and the vent valve 226. With the above settings, the gas in cavity 2202 can be released to the outside of mounting bracket 221 (outside cavity 2202) under the control of vent valve 226. When vent valve 226 malfunctions, the gas in cavity 2202 can be released by air pump 222 to improve the safety of air pump assembly 220.

[0111] Optionally, in order to more quickly release the gas from the airbag body 1122 into the cavity 2202 via the secondary control valve 225, the third through hole 2205 can also be connected to the fourth through hole 2206. That is, one opening of the third through hole 2205 can be formed on the inner wall of the fourth through hole 2206, and the end of the air guide column 2254 away from the valve body 2251 can be located in the fourth through hole 2206 to connect the fourth through hole 2206 and the valve body 2251. With this configuration, the gas released from the secondary control valve 225 can directly enter the fourth through hole 2206 and further be discharged from the vent valve 226 to the outside of the cavity 2202 without having to enter the fourth through hole 2206 through the cavity 2202, which helps to improve the venting efficiency of the air pump assembly 220. It is understandable that the placement of the vent valve 226 on the mounting bracket 221 can be adapted to design requirements, and is not limited to being placed on the periphery 2213 of the mounting bracket 221. This embodiment does not limit this.

[0112] Optionally, when the secondary control valve 225 connects the cavity 2202 to the outside atmosphere, the secondary control valve 225 can also serve as a backup valve for the vent valve 226, to vent gas from the cavity 2202, the first external air passage 2201a, and the second external air passage 2201b when both the vent valve 226 and the air pump 222 fail. Of course, when the secondary control valve 225 can connect to the outside atmosphere, the design of the vent valve 226 can be omitted, and the secondary control valve 225 and the air pump 222 can serve as backups for each other.

[0113] To measure the pressure within cavity 2202 and obtain the data needed to calculate the user's blood pressure, the air pump assembly 220 may further include a sensing element 227. For example... Figure 16 As shown, the detection element 227 can be mounted on the mounting bracket 221 and can communicate with the cavity 2202. The detection element 227 can detect the pressure inside the cavity 2202 to obtain the data needed to calculate the user's blood pressure. For example, the detection element 227 can be mounted on the bottom side 2212 of the mounting bracket 221 (bottom shell 221b), and the bottom side 2212 can have a mounting groove 2207 to accommodate the detection element 227, thereby reducing the height of the detection element 227 protruding from the bottom side 2212. At the same time, the bottom wall of the mounting groove 2207 can have a fifth through hole 2208 connecting the cavity 2202 and the detection element 227, so that the detection element 227 can indirectly measure the pressure inside the cavity 2202 through the fifth through hole 2208. It is understood that the placement of the test piece 227 on the mounting bracket 221 can be adapted to design requirements, and is not limited to being placed on the bottom side 2212 of the mounting bracket 221. This embodiment does not limit this.

[0114] Furthermore, considering the possibility of failure of the detection element 227, the number of detection elements 227 can be multiple. This allows for the use of the remaining detection elements 227 to measure the pressure in the cavity 2202 when one detection element 227 fails. Multiple detection elements 227 can also be cross-calibrated during measurement to improve the accuracy of the measured data. For example, the number of detection elements 227 can be two (…). Figure 16 (As shown), the two detection elements 227 can be a first detection element 227a and a second detection element 227b, respectively. The first detection element 227a and the second detection element 227b can be arranged opposite to each other and spaced apart, and are respectively located in two mounting grooves 2207 opened on the bottom side 2212. The orthographic projection of the valve body 2251 on the bottom side 2212 can also be located between the first detection element 227a and the second detection element 227b. Of course, the number of detection elements 227 can be two, three, four, or more; this embodiment does not limit this.

[0115] Please see Figure 17 , Figure 17 This is a frame structure diagram of the housing assembly 210, the air pump assembly 220, and the two airbags 112 provided in the embodiments of this application.

[0116] like Figure 17 As shown, the air pump 222 can be connected to the first main control valve 223 and the second main control valve 224 through the main air passage L1 (i.e., the aforementioned cavity 2202). The first main control valve 223 is configured to connect the main air passage L1 and the first external air passage 2201a, and the second main control valve 224 is configured to connect the main air passage L1 and the second external air passage 2201b. The first main control valve 223 may have a first air port 2231 connecting the main air passage L1 and the first external air passage 2201a, and the first air port 2231 can be opened or closed under the control of the first main control valve 223 to conduct or isolate the main air passage L1 and the first external air passage 2201a. Meanwhile, the second main control valve 224 may have a second air port 2241 that connects the main air passage L1 and the second external air passage 2201b, and the second air port 2241 may be opened or closed under the control of the second main control valve 224 to conduct or isolate the main air passage L1 and the second external air passage 2201b.

[0117] Furthermore, the secondary control valve 225 can be connected to the independent first external air passage 2201a and second external air passage 2201b, and can connect the first external air passage 2201a and the second external air passage 2201b. The secondary control valve 225 can have a third air port 225a connecting the first external air passage 2201a and the second external air passage 2201b, and the third air port 225a can be opened or closed under the control of the secondary control valve 225 to conduct or isolate the first external air passage 2201a and the second external air passage 2201b.

[0118] Furthermore, the vent valve 226 is configured to connect the main gas path L1 to the external atmosphere (as described in the aforementioned installation space 201), allowing gas within the main gas path L1 to vent to the external atmosphere. The vent valve 226 may have a first vent port 2261 connecting the main gas path L1 to the external atmosphere, and the vent valve 226 may open or close the first vent port 2261 to open or close the main gas path L1 to the external atmosphere. Simultaneously, the air pump 222 may also have a second vent port 2221 connecting the main gas path L1 to the external atmosphere, and the air pump 222 may also open or close the second vent port 2221 to open or close the main gas path L1 to the external atmosphere, allowing the first vent port 2261 and the second vent port 2221 to serve as backup vent ports for each other. In this embodiment, the first main control valve 223, the second main control valve 224, the auxiliary control valve 225, and the vent valve 226 can all be single-way valves. The smaller size of the single-way valve helps to reduce the space occupied by the air pump assembly 220 in the installation space 201.

[0119] Furthermore, the detection element 227 can be connected to the main air passage L1 and can detect the air pressure value within the main air passage L1 to calculate the user's blood pressure value. Simultaneously, there can be two detection elements 227, designated as a first detection element 227a and a second detection element 227b. Both the first detection element 227a and the second detection element 227b can be connected to the main air passage L1 and can simultaneously or separately detect the air pressure value within the main air passage L1. This allows the first detection element 227a and the second detection element 227b to not only serve as backup detection elements for each other but also to compare and calibrate the detected air pressure values ​​to improve measurement accuracy. In this embodiment, the detection element 227 can specifically be a barometer.

[0120] Furthermore, when the air pump 222 needs to inflate the first airbag 112a, the first main control valve 223 can connect the main air passage L1 and the first external air passage 2201a (opening the first air port 2231), the second main control valve 224 can isolate the main air passage L1 and the second external air passage 2201b (closing the second air port 2241), the auxiliary control valve 225 can isolate the first external air passage 2201a and the second external air passage 2201b (closing the third air port 225a), and the vent valve 226 and the air pump 222 can also close the first vent port 2261 and the second vent port 2221 respectively. At this time, the main air passage L1 can be connected only to the first external air passage 2201a, so that the air pump 222 can inflate the first airbag 112a through the main air passage L1 and the first external air passage 2201a.

[0121] Similarly, when the air pump 222 needs to inflate the second airbag 112b, the second main control valve 224 can connect the main air path L1 and the second external air path 2201b (opening the second air port 2241), the first main control valve 223 can isolate the main air path L1 and the second external air path 2201a (closing the first air port 2231), the auxiliary control valve 225 can isolate the first external air path 2201a and the second external air path 2201b (closing the third air port 225a), and the vent valve 226 and the air pump 222 can also close the first vent port 2261 and the second vent port 2221 respectively. At this time, the main air path L1 can be connected only to the second external air path 2201b, so that the air pump 222 can inflate the second airbag 112b through the main air path L1 and the second external air path 2201b.

[0122] Furthermore, when the first airbag 112a and / or the second airbag 112b needs to deflate, the first main control valve 223 can connect the main air passage L1 and the first external air passage 2201a (opening the first air port 2231), the second main control valve 224 can connect the main air passage L1 and the second external air passage 2201b (opening the second air port 2241), the auxiliary control valve 225 can connect the first external air passage 2201a and the second external air passage 2201b (opening the third air port 225a), and the air pump 222 and the vent valve 226 can open the first vent port 2261 and the second vent port 2221. At this time, the gas in the first airbag 112a and / or the second airbag 112b can be released into the main air passage L1 through the first main control valve 223 and the second main control valve 224, and then released to the outside atmosphere through the first vent port 2261 and the second vent port 2221.

[0123] With the above configuration, the secondary control valve 225 can be used to connect the independent first external air passage 2201a and second external air passage 2201b, allowing the first main control valve 223 and the second main control valve 224 to serve as backup valves for each other. That is, when the first main control valve 223 malfunctions, the secondary control valve 225 can connect the first external air passage 2201a and the second external air passage 2201b, guiding the gas from the first external air passage 2201a (first airbag 112a) to the second external air passage 2201b, and then releasing it through the second main control valve 224 to the main air passage L1. Finally, the gas is released to the outside atmosphere by the air pump 222 and / or the vent valve 226, reducing the safety risk caused by the inability to release gas due to a malfunction of the first main control valve. This configuration improves the safety of the air pump assembly, meeting the safety standards required for the wearable device 10 to automatically measure blood pressure at night.

[0124] Please see Figure 18 , Figure 18 This is another frame structure diagram of the housing assembly 210, air pump assembly 220 and two airbags 112 provided in the embodiments of this application.

[0125] Schemes different from the above embodiments ( Figure 17 (As shown in the diagram), the design of the vent valve 226 in this embodiment can also be omitted, and the secondary control valve 225 can have the aforementioned first vent port 2261, so as to serve as a backup vent port for the second vent port 2221 of the air pump 222. Figure 18 As shown, the difference from the above embodiment is that the secondary control valve 225 in this embodiment can also be connected to the external atmosphere, and can connect the first external air passage 2201a and the second external air passage 2201b to the external atmosphere. The secondary control valve 225 may have a fourth air port 225b, a fifth air port 225c, and a first vent port 2261. The fourth air port 225b can be connected to the first external air passage 2201a, the fifth air port 225c can be connected to the fourth air port 225b and the second external air passage 2201b, and the first vent port 2261 can be connected to the fourth air port 225b, the fifth air port 225c, and the external atmosphere. Meanwhile, the secondary control valve 225 can open or close the first vent 2261 to isolate or connect the fourth vent 225b and the fifth vent 225c to the outside atmosphere. The secondary control valve 225 can also open or close one or both of the fourth vent 225b and the fifth vent 225c to connect or isolate the first external air passage 2201a and the second external air passage 2201b.

[0126] Furthermore, when the air pump 222 needs to inflate the first airbag 112a, the first main control valve 223 can connect the main air passage L1 and the first external air passage 2201a (opening the first air port 2231), the second main control valve 224 can isolate the main air passage L1 and the second external air passage 2201b (closing the second air port 2241), and the secondary control valve 225 can isolate the first external air passage 2201a and the second external air passage 2201b (closing the fourth air port 225b and / or the fifth air port 225c). The secondary control valve 225 and the air pump 222 can also respectively close the first vent port 2261 and the second vent port 2221. At this time, the main air passage L1 can be connected only to the first external air passage 2201a, allowing the air pump 222 to inflate the first airbag 112a through both the main air passage L1 and the first external air passage 2201a.

[0127] Similarly, when the air pump 222 needs to inflate the second airbag 112b, the second main control valve 224 can connect the main air path L1 and the second external air path 2201b (opening the second air port 2241), the first main control valve 223 can isolate the main air path L1 and the second external air path 2201a (closing the first air port 2231), and the secondary control valve 225 can isolate the first external air path 2201a and the second external air path 2201b (closing the fourth air port 225b and / or the fifth air port 225c). Furthermore, the secondary control valve 225 and the air pump 222 can respectively close the first vent port 2261 and the second vent port 2221. At this time, the main air path L1 can be connected only to the second external air path 2201b, allowing the air pump 222 to inflate the second airbag 112b through the main air path L1 and the second external air path 2201b.

[0128] Furthermore, when the first airbag 112a and / or the second airbag 112b need to deflate, the first main control valve 223 can connect the main air passage L1 and the first external air passage 2201a (opening the first air port 2231), the second main control valve 224 can connect the main air passage L1 and the second external air passage 2201b (opening the second air port 2241), the auxiliary control valve 225 can connect the first external air passage 2201a and the second external air passage 2201b (opening the fourth air port 225b and the fifth air port 225c), and the auxiliary control valve 225 and the air pump 222 can also open the first vent port 2261 and the second vent port 2221 respectively. At this time, the gas in the first airbag 112a and / or the second airbag 112b can not only be released through the first vent 2261 of the secondary control valve 225, but also be released into the main air passage L1 through the first main control valve 223 and the second main control valve 224, and then released through the second vent 2221 of the air pump 222.

[0129] With the above configuration, the secondary control valve 225 can not only connect the first external air passage 2201a and the second external air passage 2201b, but also connect the external atmosphere with the first external air passage 2201a and the second external air passage 2201b. This allows the secondary control valve 225 to not only serve as a backup valve for the first main control valve 223 and the second main control valve 224, but also to directly discharge the gas from the first external air passage 2201a and the second external air passage 2201b to the external atmosphere, thus acting as a backup venting device for the air pump 222. In other words, the secondary control valve 225 and the air pump 222 can vent simultaneously, or only one can vent while the other remains a backup, thereby eliminating the need for a venting valve 226 while ensuring operational safety. Of course, in some embodiments, the venting valve 226 can be retained, and both the secondary control valve 225 and the venting valve 226 can have a first vent port 2261.

[0130] Please see Figure 19 , Figure 19This is another frame structure diagram of the housing assembly 210, air pump assembly 220 and two airbags 112 provided in the embodiments of this application.

[0131] Schemes different from the above embodiments ( Figure 17 As shown in the diagram, in this embodiment, the secondary control valve 225 can also be connected to the main air circuit L1, so that the secondary control valve 225 can also serve as a backup valve for the first main control valve 223 and the second main control valve 224. Figure 19 As shown, the difference from the above embodiment is that the secondary control valve 225 in this embodiment can also be connected to the main air passage L1, and can connect the first external air passage 2201a and the second external air passage 2201b to the main air passage L1. The secondary control valve 225 can have a fourth air port 225b, a fifth air port 225c, and a sixth air port 225d. The fourth air port 225b can be connected to the first external air passage 2201a, the fifth air port 225c can be connected to the fourth air port 225b and the second external air passage 2201b, and the sixth air port 225d can be connected to the fourth air port 225b, the fifth air port 225c, and the main air passage L1. Simultaneously, the secondary control valve 225 can also open or close either the fourth air port 225b or the fifth air port 225c to connect or disconnect the first external air passage 2201a and the second external air passage 2201b.

[0132] Furthermore, when the air pump 222 needs to inflate the first airbag 112a, the first main control valve 223 can connect the main air path L1 and the first external air path 2201a (opening the first air port 2231), the second main control valve 224 can isolate the main air path L1 and the second external air path 2201b (closing the second air port 2241), the auxiliary control valve 225 can isolate the first external air path 2201a and the second external air path 2201b (closing the fifth air port 225c), and the vent valve 226 and the air pump 222 can also close the first vent port 2261 and the second vent port 2221 respectively. At this time, the main air path L1 can be connected to the first external air path 2201a through the first main control valve 223 and the auxiliary control valve 225, so that the air pump 222 can inflate the first airbag 112a through the main air path L1 and the first external air path 2201a.

[0133] Similarly, when the air pump 222 needs to inflate the second airbag 112b, the second main control valve 224 can connect the main air path L1 and the second external air path 2201b (opening the second air port 2241), the first main control valve 223 can isolate the main air path L1 and the second external air path 2201a (closing the first air port 2231), and the auxiliary control valve 225 can isolate the first external air path 2201a and the second external air path 2201b (closing the fourth air port 225b). Furthermore, the vent valve 226 and the air pump 222 can respectively close the first vent port 2261 and the second vent port 2221. At this time, the main air path L1 can be connected to the second external air path 2201b through the second main control valve 224 and the auxiliary control valve 225, allowing the air pump 222 to inflate the second airbag 112b through the main air path L1 and the second external air path 2201b.

[0134] Furthermore, when the first airbag 112a and / or the second airbag 112b need to deflate, the first main control valve 223 can connect the main air passage L1 and the first external air passage 2201a (opening the first air port 2231), the second main control valve 224 can connect the main air passage L1 and the second external air passage 2201b (opening the second air port 2241), the auxiliary control valve 225 can connect the first external air passage 2201a and the second external air passage 2201b (opening the fourth air port 225b and the fifth air port 225c), and the deflation valve 226 and the air pump 222 can also open the first deflation port 2261 and the second deflation port 2221 respectively. At this time, the gas in the first airbag 112a and / or the second airbag 112b can be released into the main air passage L1 through the first main control valve 223, the second main control valve 224 and the auxiliary control valve 225, and then released into the outside atmosphere through the first vent 2261 and the second vent 2221.

[0135] With the above configuration, the secondary control valve 225 can also serve as a backup valve for the first main control valve 223 and the second main control valve 224, and is connected to the main air passage L1 to form a redundant air passage design. When the first main control valve 223 and / or the second main control valve 224 malfunction and cannot connect the main air passage L1 with the first external air passage 2201a and / or the second external air passage 2201b, the gas in the first external air passage 2201a and the second external air passage 2201b can be released into the main air passage L1 under the control of the secondary control valve 225, so as to avoid the risk of bursting due to the inability of the airbag body 1122 to release gas in time, thereby further improving the safety of the air pump assembly 220 and ultimately meeting the safety standards required for the wearable device 10 to automatically measure blood pressure at night.

[0136] Please combine Figure 9 See Figures 20 to 21 , Figure 20 yes Figure 9 A structural diagram of the unlocking component 240. Figure 21 yes Figure 1A schematic diagram of a partial cross-sectional structure of the wearable device 10 along XI-XI.

[0137] like Figure 9 and Figures 20 to 21 As shown, the unlocking component 240 is slidably disposed within the slide groove 2002 and can slide in the thickness direction of the meter mechanism 200. When the latching part 1214 is inserted into the slot 2001, the unlocking component 240 can be pushed and displaced by the latching part 1214 to avoid the insertion of the latching part 1214. At the same time, after the latching part 1214 is inserted into place, the unlocking component 240 can also reset and snap into the slot 12141 to engage with the latching part 1214. In addition, the unlocking component 240 is also exposed on the side of the back cover 212 opposite to the top surface 2111 and can be disengaged from the slot 12141 by the user to release the engagement with the latching part 1214. With this configuration, the unlocking component 240 can achieve a detachable connection between the latching part 1214 and the meter mechanism 200. The structure of the unlocking component 240 will be further explained below.

[0138] The unlocking component 240 includes a slider 241 and an elastic element 242. The slider 241 is disposed within a groove 2002 and can slide within the groove 2002 along the thickness direction of the dial mechanism 200. A portion of the slider 241 is also located within a slot 2001. When the latching part 1214 is inserted into the slot 2001, the slider 241 can be pushed away by the latching part 1214 and can reset after the latching part 1214 is fully inserted, thus engaging with the latching part 1214 within the slot 12141. Simultaneously, the slider 241 also extends through the back cover 212 and is exposed on the side of the back cover 212 opposite to the top surface 2111. The user can press the slider 241 on the back cover 212 to disengage it from the slot 12141, thereby releasing the engagement between the slider 241 and the latching part 1214. The elastic element 242 is disposed between the sliding element 241 and the bottom wall of the groove 2002. When the sliding element 241 is pushed by the latching part 1214 or pressed by the user, the elastic element 242 can be elastically deformed by the sliding element 241 to provide elastic force to drive the sliding element 241 to reset.

[0139] It is understood that the structure of the aforementioned unlocking component 240 is merely illustrative. In some embodiments, the structure of the unlocking component 240 may not be limited to this, as long as the unlocking component 240 can cooperate with the buckle portion 1214 to achieve a detachable connection. Furthermore, besides the detachable connection method of the strap mechanism 100 and the watch head mechanism 200 shown in the aforementioned embodiments, the strap mechanism 100 and the watch head mechanism 200 may also be detachably connected using other methods such as spring bar pins or magnetic attraction. As long as the strap mechanism 100 and the watch head mechanism 200 are detachably connected, the strap mechanism 100 can still communicate with the watch head mechanism 200. This embodiment does not limit this. Moreover, when the strap mechanism 100 and the watch head mechanism 200 are non-detachably connected, the design of the unlocking component 240 can also be omitted.

[0140] Please see Figure 22 , Figure 22 This is a schematic flowchart of a blood pressure detection method provided in an embodiment of this application. This blood pressure detection method can be applied to the wearable device 10 described above and may include the following steps:

[0141] S10, in the first state or the second state, responds to the blood pressure detection command, controls the first main control valve to open the main air path and the first external air path, controls the second main control valve to isolate the main air path and the second external air path, controls the auxiliary control valve to isolate the first external air path and the second external air path, and closes the first vent and the second vent.

[0142] S20, control the air pump to inflate the first airbag, and when the first detection element and / or the second detection element detect that the air pressure value of the main air path meets the first preset condition, control the first main control valve to isolate the main air path and the first external air path.

[0143] S30, control the second main control valve to open the main air passage and the second external air passage, control the auxiliary control valve to isolate the first external air passage and the second external air passage, so that the air pump inflates the second airbag, and when the first detection element and / or the second detection element detect that the air pressure value of the main air passage meets the second preset condition, control the air pump to stop inflating.

[0144] S40, calculate the blood pressure value based on the partial or complete air pressure values ​​measured by the first and / or second detection devices during the inflation of the first and / or second airbags.

[0145] S50, control the first main control valve to connect the main air path and the first external air path, control the second main control valve to connect the main air path and the second external air path, control the auxiliary control valve to connect the first external air path and the second external air path, and open the first vent and the second vent to deflate the first airbag and the second airbag.

[0146] Specifically, the blood pressure detection command can be automatically or passively triggered in a first state or a second state. The first state can include: the user being in an unconscious state, or the current time being a first preset time. The user being in an unconscious state refers to a state of sleep, anesthesia, or coma, where the user is unconscious or has weak consciousness. The wearable device 10 can autonomously detect whether the user is in an unconscious state and automatically trigger the blood pressure detection command when it detects this, thus performing blood pressure detection on the unconscious user. For example, when the user is asleep, the wearable device 10 can determine whether the user is asleep by detecting the user's heart rate, blood oxygen, and snoring, and can trigger the blood pressure detection command after confirming that the user is asleep, and then perform blood pressure detection on the user in response to the command.

[0147] The current time being within the first preset time refers to the current time being within a user-preset first time point or first time period. The wearable device 10 can passively trigger a blood pressure detection command when the current time is within the user-preset first time point or first time period to perform blood pressure monitoring on the user. For example, the user can preset the first time point or first time period for triggering the blood pressure monitoring command in the wearable device 10, such as 10 PM or 10 PM to 8 AM. When the wearable device 10 detects that the current time is 10 PM or within the 10 PM to 8 AM period, the wearable device 10 can passively trigger the blood pressure monitoring command and perform blood pressure monitoring on the user in response to the command. In this embodiment, the first preset time can be a specific time point or time period at night, such as midnight or 11 PM to 3 AM.

[0148] The second state can include: the user being awake, or the current time being a second preset time. Being awake means the user is in a conscious or strongly conscious state, such as exercising, working, or engaging in leisure activities. The wearable device 10 can autonomously detect whether the user is awake and automatically trigger a blood pressure detection command when it detects that the user is awake, in order to measure the user's blood pressure. For example, when the user is exercising, the wearable device 10 can determine whether the user is exercising by detecting the user's heart rate, blood oxygen, and body temperature, and can trigger a blood pressure detection command after confirming that the user is exercising, and then measure the user's blood pressure in response to the blood pressure detection command.

[0149] The current time being within the second preset time refers to the current time being within a second preset time point or second time period, and the wearable device 10 can passively trigger a blood pressure detection command to perform blood pressure detection on the user when the current time is within the user-preset second time point or second time period. For example, the user can preset the second time point or second time period for triggering the blood pressure detection command in the wearable device 10 in advance, such as 9:00 AM or 9:00 AM to 2:00 PM. When the wearable device 10 detects that the current time is 9:00 AM or between 9:00 AM and 2:00 PM, the wearable device 10 can passively trigger the blood pressure detection command and perform blood pressure detection on the user in response to the blood pressure detection command. In this embodiment, the second preset time may be different from the first preset time, and the second preset time may be a certain time point or time period during the day, such as 9:00 PM or 9:00 AM to 5:00 PM, etc.

[0150] In some embodiments, when the first preset time and the second preset time are time periods, the user can also preset the number of times and frequency of triggering the blood pressure monitoring command on the wearable device 10. For example, the user can preset the time period for the blood pressure monitoring command to be from 11 PM to 2 AM on the wearable device 10, and trigger the blood pressure monitoring command once every hour during this time period to monitor the user's blood pressure multiple times during this time period. In addition, the first preset time and the second preset time are not limited to nighttime or daytime, and the first preset time and the second preset time can also be customized by the user.

[0151] When the blood pressure detection command is triggered, the wearable device 10 can respond to the blood pressure detection command by controlling the first main control valve 223 to open the main air passage L1 and the first external air passage 2201a, controlling the second main control valve 224 to isolate the main air passage L1 and the second external air passage 2201b, controlling the secondary control valve 225 to isolate the first external air passage 2201a and the second external air passage 2201b, and closing the first vent 2261 and the second vent 2221, so that the main air passage L1 is connected to the first external air passage 2201a.

[0152] When the main air passage L1 is connected to the first external air passage 2201a, the wearable device 10 can control the air pump 222 to inflate the first airbag 112a. When the first detection element 227a and / or the second detection element 227b detects that the air pressure value of the main air passage L1 meets the first preset condition, the device 10 controls the first main control valve 223 to isolate the main air passage L1 from the first external air passage 2201a. The first preset condition may refer to the detection of a pulse signal by the first detection element 227a and / or the second detection element 227b (that is, the detected air pressure value reaches a preset air pressure threshold), which means that the first airbag 112a is sufficiently close to the user's wrist.

[0153] When the first airbag 112a is fully inflated, that is, after the first main control valve 223 isolates the main air passage L1 and the first external air passage 2201a, the wearable device 10 can control the second main control valve 224 to connect the main air passage L1 and the second external air passage 2201b, and control the secondary control valve 225 to isolate the first external air passage and the second external air passage, so that the main air passage L1 can be connected to the second external air passage 2201b, thereby allowing the air pump 222 to inflate the second airbag 112b.

[0154] When the first detection element 227a and / or the second detection element 227b detects that the air pressure value of the main air passage L1 meets the second preset condition, the wearable device 10 can control the air pump 222 to stop inflating, and can calculate the blood pressure value based on part or all of the air pressure values ​​measured by the first detection element 227a and / or the second detection element 227b during the inflation of the first airbag 112a and / or the second airbag 112b. The second preset condition may refer to the first detection element 227a and / or the second detection element 227b detecting the disappearance of the pulse signal (i.e., the detected air pressure value reaches another preset air pressure threshold), which indicates that the second airbag 112b has compressed and blocked the blood vessels in the user's wrist. Furthermore, the calculation method for calculating the blood pressure value based on the detected air pressure value can refer to existing technologies, and will not be elaborated here.

[0155] Once the wearable device 10 calculates the blood pressure value, that is, after the blood pressure detection is completed, the wearable device 10 can control the first main control valve 223 to open the main air passage L1 and the first external air passage 2201a, control the second main control valve 224 to open the main air passage L1 and the second external air passage 2201b, control the secondary control valve 225 to open the first external air passage 2201a and the second external air passage 2201b, and open the first vent 2261 and the second vent 2221 to deflate the first airbag 112a and the second airbag 112b, thereby completing the entire blood pressure detection process.

[0156] The air pump assembly 220 provided in this application, by setting a secondary control valve 225 to connect to an independent first external air passage 2201a and a second external air passage 2201b, allows the first main control valve 223, which connects to the first external air passage 2201a, and the second main control valve 224, which connects to the second external air passage 2201b, to serve as backup valves for each other. That is, when the first main control valve 223 fails, the secondary control valve 225 can connect the first external air passage 2201a and the second external air passage 2201b, guiding the gas from the first external air passage 2201a to the second external air passage 2201b, and then releasing it to the main air passage L1 (cavity 2202) through the second main control valve 224. This reduces the safety risk caused by the inability to release gas due to a failure of the first main control valve 223, thereby improving the safety of the air pump assembly 220 in use.

[0157] The above description is only a part of the embodiments of this application and does not limit the scope of protection of this application. Any equivalent device or equivalent process transformation made based on the content of this application specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this application.
