Abstract
Description
Technical Field
[0001] This invention relates to the field of smart wearable technology, and in particular to a smart skin-adhesive device. Background Technology
[0002] Currently, patch technology is widely used in health monitoring, drug delivery, and skin care. These devices typically employ flexible printed circuit technology to integrate sensors, microcontrollers, and wireless communication modules onto the patch, which is then tightly fitted to the surface of the human skin to achieve non-invasive, continuous acquisition of physiological signals such as heart rate, body temperature, and muscle activity.
[0003] Currently, most patch devices consist of a separate patch component and a mounting base. During use, the patch component must first be installed onto the mounting base before the entire device is applied to the skin. However, during use, the patch component is susceptible to external forces from various directions, which can cause it to detach or loosen unexpectedly. This could result in the patch component detaching directly from the skin, abruptly interrupting the monitoring or treatment process. Summary of the Invention
[0004] The main objective of this invention is to provide an intelligent skin-applying device that improves the connection reliability of the fixing component and the patch component, thereby enhancing the reliability of the intelligent skin-applying device in use.

[0007] In one embodiment, the first direction is the axial direction of the patch assembly, and the second direction is the circumferential direction of the patch assembly; The first limiting structure includes a first limiting boss disposed on the side of the patch assembly and a first limiting groove disposed on the inner surface of the fixing assembly, wherein the first limiting boss and the first limiting groove are mechanically engaged. The second limiting structure includes a first magnetic element disposed on the patch assembly and a second magnetic element disposed on the fixing assembly, wherein the first magnetic element and the second magnetic element are attracted to each other.
[0008] In one embodiment, the patch assembly includes a patch housing, and the fixing assembly includes a fixing seat; the first limiting groove extends on the fixing seat along the second direction and has a first opening in the first direction; the first limiting boss protrudes outward from the patch housing; The first limiting protrusion is inserted into the first limiting groove from the first opening and rotates along the second direction to the bottom of the first limiting groove, so that the first limiting protrusion abuts against the groove wall of the first limiting groove in the first direction.
[0009] In one embodiment, the first limiting groove is provided with multiple stepped positions, and when the first limiting boss abuts against different stepped positions, the contact pressure between the patch assembly and the skin is different.
[0010] In one embodiment, the first magnetic element is disposed on the side of the patch housing facing the fixing assembly, and the second magnetic element is disposed on the side of the fixing base facing the patch assembly; after the patch assembly and the fixing assembly are installed in place, the first magnetic element and the second magnetic element attract each other in the first direction.
[0011] In one embodiment, the fixing base is provided with multiple sets of second magnetic elements. When the first limiting boss moves from one of the stepped positions to another stepped position, the first magnetic element switches to cooperate with another set of second magnetic elements for adsorption.
[0012] In one embodiment, the patch assembly includes a patch housing and a first detection element mounted on the skin-facing side of the patch housing, the first detection element being used to contact the skin to detect human information; Wherein, the first detection element is configured as a heart rate detection module; and / or, the first detection element is convex relative to the patch housing.
[0013] In one embodiment, the fixing component further includes a second detection element for contacting the skin to detect human information; The patch assembly includes a main board disposed within the patch housing and an electrical connector electrically connected to the main board, with at least a portion of the electrical connector extending out of the patch housing; the second detection element is electrically connected to the main board via the electrical connector.
[0014] In one embodiment, the fixing component includes an adhesive member, one side of which has an adhesive area and a non-adhesive area, the non-adhesive area on which the second detection element is mounted, and the adhesive area for adhesion to the skin; Alternatively, the fixing component includes an adapter, one side of which has an adhesive area and an installation area, the second detection element is installed in the installation area, the adhesive area is detachably bonded with double-sided adhesive, and the other side of the double-sided adhesive is used for adhesion to the skin; The fixing component includes a fixing base, and the non-adhesive area or the mounting area is provided with a first clearance hole.

The mounting rib passes through the first clearance hole and is embedded in the mounting hole, so that the second detection element is connected to the fixing base.
[0016] The technical solution of this invention provides a smart skin-adhesive device by incorporating a fixing component, a patch component, a first limiting structure, and a second limiting structure. The fixing component is adhered to the skin, and the patch component is detachably connected to the fixing component. The first limiting structure is located between the fixing component and the patch component to restrict movement of the patch component relative to the fixing component in a first direction after the patch component is attached to the fixing component, thus preventing the patch component from moving away from the skin. The second limiting structure is located between the fixing component and the patch component to restrict movement of the patch component relative to the fixing component in a second direction after the patch component is attached to the fixing component, thus preventing the first limiting structure from failing. Therefore, compared to the prior art which lacks a limiting structure, this invention provides both a first limiting structure and a second limiting structure in the smart skin-adhesive device, thereby limiting the connection between the patch component and the fixing component from multiple directions, ensuring the reliability of the connection, and improving the reliability of the smart skin-adhesive device.

[0024] Currently, patch technology is widely used in health monitoring, drug delivery, and skin care. These devices typically employ flexible printed circuit technology to integrate sensors, microcontrollers, and wireless communication modules onto the patch, which is then tightly fitted to the surface of the human skin to achieve non-invasive, continuous acquisition of physiological signals such as heart rate, body temperature, and muscle activity.
[0025] Currently, most patch devices on the market adopt a split design for ease of production, sensor module replacement, or battery life. This structure typically includes a patch section and a mounting section. The patch section integrates the core electronic components, while the mounting section provides the connection to the skin. In use, the patch section must first be installed onto the mounting section, and then the entire device is applied to the skin.
[0026] However, in daily activities, the human skin undergoes complex processes such as stretching, wrinkling, sweating, and friction from clothing, subjecting the patch to external forces from multiple directions, including shearing and peeling. Existing connection methods are prone to accidental detachment or loosening under these forces. Once separated, the patch may detach directly from the skin, causing abrupt interruptions in monitoring or treatment, data loss, and severely impacting the continuity and stability of the device. In medical scenarios requiring reliable data streams for health monitoring or timed drug administration, this issue can lead to incomplete diagnostic information or treatment failure.
[0027] This invention proposes an intelligent skin-applying device.
[0028] Please see Figure 1 In one embodiment of the present invention, the smart skin-adhesive device includes a fixing component 100, a patch component 200, a first limiting structure (not shown), and a second limiting structure (not shown). The fixing component 100 is used to adhere to the skin. The patch component 200 is detachably connected to the fixing component 100. The first limiting structure is disposed between the fixing component 100 and the patch component 200 to restrict the movement of the patch component 200 relative to the fixing component 100 in a first direction after the patch component 200 is installed on the fixing component 100, so as to prevent the patch component 200 from moving away from the skin side. The second limiting structure is disposed between the fixing component 100 and the patch component 200 to restrict the movement of the patch component 200 relative to the fixing component 100 in a second direction after the patch component 200 is installed on the fixing component 100, so as to prevent the limiting of the first limiting structure from failing.
[0029] For ease of explanation, the smart skin-adhesive device is defined as having a relative upper and lower part, with the side closer to the skin being the lower part. It is understood that the patch assembly 200 has a contact end with a detection element located below it. This detection element detects human information upon contact with the skin. The fixing assembly 100 has a fixing end for securing to the skin, located below it. The patch assembly 200 needs to be mounted onto the fixing assembly 100 for use. Correspondingly, the fixing assembly 100 has detection clearance holes to allow the contact end of the patch assembly 200 to expose and contact the skin.
[0030] Understandably, after the patch assembly 200 is installed onto the fixing assembly 100, the connection between the two needs to be limited in multiple directions to improve the stability and reliability of the connection. Specifically, a first limiting structure and a second limiting structure are provided between the fixing assembly 100 and the patch assembly 200. When the patch assembly 200 is installed onto the fixing assembly 100, the first limiting structure is used to restrict the movement of the patch assembly 200 in a first direction, thereby preventing the patch assembly 200 from moving away from the skin side, that is, preventing the contact end from separating from the skin. The second limiting structure is used to restrict the movement of the patch assembly 200 in a second direction. Understandably, the movement of the patch assembly 200 in the second direction will cause the limiting of the first limiting structure to fail. That is, the movement of the patch assembly 200 in the second direction will eventually cause the patch assembly 200 to move in the first direction, thereby causing the contact end of the patch assembly 200 to move away from the skin.
[0031] Thus, by simultaneously setting a first limiting structure and a second limiting structure in the smart skin-applying device, the connection between the patch assembly 200 and the fixing assembly 100 can be limited from both the first and second directions. This achieves multi-directional limiting of the patch assembly 200 and the fixing assembly 100, improving the connection stability and reliability of the two components, and also enhancing the reliability of the smart skin-applying device in use.
[0032] Understandably, smart skin-mounted devices can be used on humans to detect health and activity information, such as heart rate, blood oxygen, and heartbeat. They can also be used on animals, for purposes such as pet therapy and animal research; therefore, we will not limit the application scenarios of smart skin-mounted devices.
[0033] The technical solution of this invention involves setting a fixing component 100, a patch component 200, a first limiting structure, and a second limiting structure in a smart skin-applying device. The fixing component 100 is adsorbed onto the skin, and the patch component 200 is detachably connected to the fixing component 100. The first limiting structure is located between the fixing component 100 and the patch component 200 to restrict the movement of the patch component 200 relative to the fixing component 100 in a first direction after the patch component 200 is installed onto the fixing component 100, thereby preventing the patch component 200 from moving away from the skin. The second limiting structure is located between the fixing component 100 and the patch component 200 to restrict the movement of the patch component 200 relative to the fixing component 100 in a second direction after the patch component 200 is installed onto the fixing component 100, thereby preventing the limiting structure from failing. Thus, compared to the unlimited positioning structure in the prior art, the present invention provides a first limiting structure and a second limiting structure in the smart skin-applying device, thereby limiting the connection between the patch assembly 200 and the fixing assembly 100 from multiple directions, ensuring the connection reliability of the patch assembly 200 and the fixing assembly 100, and improving the reliability of the smart skin-applying device.
[0034] Please see Figure 1 In an embodiment of the present invention, the first direction is the axial direction of the patch assembly 200, and the second direction is the circumferential direction of the patch assembly 200; the first limiting structure includes a first limiting boss 211 disposed on the side of the patch assembly 200 and a first limiting groove 111 disposed on the inner surface of the fixing assembly 100, and the first limiting boss 211 and the first limiting groove 111 are mechanically engaged; The second limiting structure includes a first magnetic element 260 disposed on the patch assembly 200 and a second magnetic element 160 disposed on the fixing assembly 100, wherein the first magnetic element 260 and the second magnetic element 160 are attracted to each other.
[0035] Understandably, in the embodiment shown in the figures of this invention, the smart skin-applying device is generally circular in structure, wherein the patch assembly 200 is generally circular and the fixing assembly 100 is generally annular, with the patch assembly 200 mounted on the inner ring portion of the fixing assembly 100. The patch assembly 200 includes a patch housing 210, and the fixing assembly 100 includes a fixing base 110, which has a detection clearance hole through which the contact end of the patch assembly 200 protrudes. The patch housing 210 is rotatable relative to the fixing base 110, thereby enabling the installation or separation of the patch assembly 200 and the fixing assembly 100. In this embodiment, the first direction is the axial direction of the patch assembly 200, that is, the upward movement of the patch assembly 200 relative to the fixing assembly 100 in the axial direction allows the patch assembly 200 to move away from the skin. The second direction is the circumferential direction of the patch assembly 200. That is, the rotation of the patch assembly 200 relative to the fixed assembly 100 in the circumferential direction will cause the patch assembly 200 to break away from the restriction of the first limiting structure, and eventually cause the patch assembly 200 to move away from the skin.
[0036] In one embodiment, the first limiting structure includes a first limiting boss 211 and a first limiting groove 111. Through the mechanical engagement of the first limiting boss 211 and the first limiting groove 111, the movement of the patch assembly 200 relative to the fixing assembly 100 is restricted in the first direction, that is, in the axial direction of the patch assembly 200, thereby preventing the patch assembly 200 from separating from the skin.
[0037] The second limiting structure includes a first magnetic element 260 and a second magnetic element 160. Through the magnetic attraction of the first magnetic element 260 and the second magnetic element 160, the movement of the patch assembly 200 relative to the fixed assembly 100 is limited in the second direction, that is, in the circumferential direction of the patch assembly 200, thereby preventing the limiting structure of the first limiting structure from failing.
[0038] Thus, in this invention, the first limiting structure is a mechanical structure, and the second limiting structure is a magnetic structure. The combination of these two structures improves the connection reliability between the patch assembly 200 and the fixing assembly 100. Of course, in other embodiments, the second limiting structure can also be a snap-fit structure; this is not a limitation.
[0039] Of course, in other embodiments, the smart skin-applying device can also be a rectangular, elliptical, or other structure. Taking a rectangular shape as an example, the patch assembly 200 can be installed or separated from the fixed assembly 100 by sliding relative to it. In this case, the first direction is the vertical direction, and the second direction is the horizontal direction, that is, the direction parallel to the plane of the skin.
[0040] Please see Figure 2 and Figure 3In an embodiment of the present invention, the patch assembly 200 includes a patch housing 210, and the fixing assembly 100 includes a fixing base 110. The fixing base 110 is provided with a first limiting groove 111, which extends in a second direction and has a first opening 112 in a first direction. The patch housing 210 is provided with an outwardly protruding first limiting boss 211. The first limiting boss 211 is engaged with the first limiting groove 111 from the first opening 112 and rotates in the second direction to the bottom of the first limiting groove 111, so that in the first direction, the first limiting boss 211 abuts against the groove wall of the first limiting groove 111.
[0041] Understandably, in the embodiment shown in the figures of this invention, the first limiting structure includes a first limiting groove 111 and a first limiting boss 211. Specifically, the fixing base 110 is generally annular in shape, and the inner side of the peripheral sidewall of the fixing base 110 is provided with the first limiting groove 111. The first limiting groove 111 extends circumferentially along the intelligent skin-applying device to have a certain length, and the first limiting groove 111 also has a first opening 112 facing upward. The patch housing 210 is generally circular in shape, and the first limiting boss 211 is provided at the edge of the patch housing 210 and protrudes outward. In one embodiment, the first limiting boss 211 and the patch housing 210 are integrally formed to facilitate the processing of the patch assembly 200.
[0042] When the patch assembly 200 is installed onto the fixing assembly 100, the first limiting boss 211 of the patch assembly 200 is aligned with the first opening 112 on the fixing assembly 100. Then, the patch assembly 200 is placed downwards, so that the first limiting boss 211 enters the first limiting groove 111 through the first opening 112. Then, the patch assembly 200 is rotated circumferentially, so that the first limiting boss 211 moves toward the bottom of the first limiting groove 111. When the first limiting boss 211 rotates to the bottom of the first limiting groove 111, the upper sidewall of the first limiting boss 211 abuts against the upper groove wall of the first limiting groove 111, thereby restricting the upward movement of the first limiting boss 211 in the axial direction, thereby restricting the upward movement of the patch housing 210, and further restricting the upward movement of the patch assembly 200, thus preventing the patch assembly 200 from separating from the skin.
[0043] Understandably, to ensure the stability and balance of the connection between the patch assembly 200 and the fixing assembly 100, in one embodiment, two first limiting protrusions 211 are provided, symmetrically arranged. Correspondingly, two first limiting grooves 111 are also provided. When the patch assembly 200 and the fixing assembly 100 are connected, one first limiting protrusion 211 engages with one first limiting groove 111. Of course, in other embodiments, three or four first limiting protrusions 211 and first limiting grooves 111 may be provided, which is not limited here.
[0044] Of course, in other embodiments, the first limiting structure may also include a limiting part and a buckle. The limiting part is disposed on the patch housing 210, and the buckle is movably mounted on the fixing base 110. When the patch housing 210 is mounted on the fixing base 110, the buckle is moved to abut against the limiting part, thereby restricting the upward movement of the patch assembly 200.
[0045] Please see Figure 4 In an embodiment of the present invention, the first limiting groove 111 is provided with a plurality of stepped positions 113. When the first limiting boss 211 abuts against different stepped positions 113, the contact pressure between the patch assembly 200 and the skin is different.
[0046] Understandably, in different usage scenarios or for different users, the patch assembly 200 in a smart skin-applying device needs to have different contact pressures with the skin to improve the accuracy of the device. Therefore, multiple stepped positions 113 are provided within the first limiting groove 111, arranged circumferentially at intervals. Furthermore, the heights of the multiple stepped positions 113 differ vertically, resulting in different lengths of the portion of the patch assembly 200 extending beyond the detection clearance hole of the fixing seat 110 when the first limiting boss 211 of the patch assembly 200 engages with different stepped positions 113. That is, when the first limiting boss 211 switches between different stepped positions 113, the pressure between the patch assembly 200 and the skin changes.
[0047] Specifically, taking the first limiting groove 111 having two stepped positions 113 as an example, after the patch assembly 200 is placed onto the fixing assembly 100 through the first opening 112, the patch assembly 200 is rotated so that the first limiting boss 211 of the patch assembly 200 moves to the first stepped position 113. At this time, there is a first contact pressure between the patch assembly 200 and the skin. When it is necessary to increase the contact pressure, the patch assembly 200 is pressed down at the first stepped position 113 so that the first limiting boss 211 of the patch assembly 200 disengages from the first stepped position 113. At this time, the contact pressure between the patch assembly 200 and the skin increases. Then, the patch assembly 200 is rotated further so that it rotates towards the second stepped position 113. When the first limiting boss 211 is stuck at the second stepped position 113, there is a second contact pressure between the patch assembly 200 and the skin. When it is necessary to reduce the contact pressure, rotate the patch assembly 200 in the opposite direction so that the first limiting boss 211 moves to the first step position 113.
[0048] Thus, the present invention provides multiple stepped positions 113 in the fixing base 110 of the intelligent skin-applying device. By the overlapping and cooperation of the first limiting boss 211 of the patch body with different stepped positions 113, the intelligent skin-applying device and the skin have different contact pressures, realizing active and flexible control of contact pressure, improving the accuracy of signal acquisition, monitoring, etc., thereby meeting the usage needs of different users and the usage needs of different testing projects. The intelligent skin-applying device provided by the present invention has a relatively wide range of applications.
[0049] Please see Figure 3 , Figure 5 and Figure 6 In an embodiment of the present invention, a first magnetic element 260 is installed on the side of the patch housing 210 facing the fixing component 100, and a second magnetic element 160 is installed on the side of the fixing base 110 facing the patch assembly 200; after the patch assembly 200 and the fixing component 100 are installed in place, the first magnetic element 260 and the second magnetic element 160 attract each other in a first direction.
[0050] Understandably, the patch housing 210 has a first magnetic element 260 mounted on its end facing the fixing assembly 100. In one embodiment, the patch housing 210 has a first magnetic mounting groove at its lower part, and the first magnetic element 260 is mounted in the first magnetic mounting groove by snap-fit and / or adhesive bonding. Understandably, to avoid interference between the first magnetic element 260 and other components of the patch assembly 200, in one embodiment, the first magnetic mounting groove is not in communication with the interior of the patch housing 210. The fixing base 110 has a second magnetic element 160 mounted on its end facing the patch assembly 200. In one embodiment, the fixing base 110 has a second magnetic mounting groove at its upper part, and the second magnetic element 160 is mounted in the second magnetic mounting groove by snap-fit and / or adhesive bonding.
[0051] When the first limiting protrusion 211 of the patch assembly 200 enters the first opening 112 of the first limiting groove 111, the first magnetic element 260 and the second magnetic element 160 are not yet aligned, and there is no attraction between them. When the patch assembly 200 rotates until the first limiting protrusion 211 is engaged with the bottom of the first limiting groove 111, the first magnetic element 260 and the second magnetic element 160 are aligned, and there is a magnetic attraction between them in the vertical direction. Under the action of this magnetic attraction, the rotation of the patch assembly 200 relative to the fixing assembly 100 is restricted, thereby preventing the first limiting protrusion 211 from falling out of the first limiting groove 111, and thus preventing the patch assembly 200 from moving upward and separating from the skin.
[0052] In one embodiment, to ensure the limiting effect and limiting balance of the second limiting structure, multiple first magnetic elements 260 and second magnetic elements 160 are provided at intervals. In the scheme shown in the figure of the present invention, two first magnetic elements 260 and two magnetic elements 160 are provided. The two first magnetic elements 260 are symmetrically arranged, and correspondingly, the two second magnetic elements 160 are also symmetrically arranged.
[0053] Of course, in other embodiments, the second limiting structure may also include a retractable slide rod and a groove. A retractable slide rod is provided below the patch housing 210, and a slide rail is provided above the fixing base 110, with a groove in the slide rail. As the patch assembly 200 rotates, the retractable slide rod slides in the slide rail under compression. When the first limiting boss 211 engages with the first limiting groove 111, the retractable slide rod slides to the groove and is partially extended, thus locking the retractable slide rod in the groove and restricting its continued sliding.
[0054] Please see Figure 3 In an embodiment of the present invention, the fixing base 110 is provided with multiple sets of second magnetic elements 160. When the first limiting boss 211 moves from one step position 113 to another step position 113, the first magnetic element 260 switches to cooperate with another set of second magnetic elements 160 for adsorption.
[0055] Understandably, when the first limiting groove 111 has multiple stepped positions 113, the corresponding fixing base 110 has multiple sets of second magnetic components 160. Taking an example where there are two stepped positions 113 and two sets of second magnetic components 160: When the first limiting boss 211 of the patch assembly 200 enters the first limiting groove 111 through the first opening 112, the first magnetic component 260 and the first set of second magnetic components 160 are not yet aligned circumferentially. As the patch assembly 200 rotates, when the first limiting boss 211 and the first stepped position 113 engage, the first magnetic component 260 and the first set of second magnetic components 160 are aligned axially, and there is a first gap between them axially. That is, in the vertical direction, the first magnetic component 260 and the first set of second magnetic components 160 do not contact each other. At this time, there is an axial adsorption force between them. Subsequently, the patch assembly 200 continues to rotate, and the first limiting boss 211 moves to the second step position 113. At this time, in the axial direction, the first magnetic element 260 and the second magnetic element 160 of the second group are aligned, and there is an attractive force between them. At this time, in the axial direction, the first magnetic element 260 and the second magnetic element 160 of the second group can be in contact or have a second gap, which is smaller than the first gap.
[0056] Thus, the arrangement of multiple sets of second magnetic components 160 ensures that when the smart skin-applying device switches between different contact pressures, that is, when the patch assembly 200 switches to different step positions 113, the second limiting structure can always restrict the rotation of the patch assembly 200.
[0057] Understandably, in order to ensure that the adsorption force between the second magnetic component 160 and the first magnetic component 260 in the first group is the same as the adsorption force between the second magnetic component 160 and the first magnetic component 260 in the second group, so as to ensure the consistency of the limiting effect of the second limiting structure under different contact pressures, in one embodiment, the size, thickness, etc. of the second magnetic component 160 in the first group and the second magnetic component 260 in the second group can be adjusted.
[0058] Please see Figure 2 , Figure 6 and Figure 7 In an embodiment of the present invention, the patch assembly 200 further includes a patch housing 210 and a first detection element 220 mounted on the side of the patch housing 210 facing the skin. The first detection element 220 is used to contact the skin to detect human information. The first detection element 220 is configured as a heart rate detection module; and / or, the first detection element 220 is convex relative to the patch housing 210.
[0059] Understandably, the contact end of the patch assembly 200 is equipped with a first detection element 220 to allow the first detection element 220 to directly contact the skin and improve detection accuracy. In one embodiment, the first detection element 220 is installed on the skin-facing side of the patch housing 210, thus exposing the first detection element 220 to the patch housing 210. Therefore, when the patch assembly 200 is mounted onto the fixing assembly 100, the first detection element 220 can be exposed through the detection clearance hole of the fixing housing.
[0060] In one embodiment, the first detection element 220 is configured as a heart rate detection module. Of course, the first detection element 220 can also be other detection elements, which are not limited here.
[0061] In one embodiment, the first detection element 220 is disposed to protrude downward relative to the patch housing 210, thereby facilitating the exposure of the first detection element 220 to the detection avoidance hole and facilitating the contact between the first detection element 220 and the skin.
[0062] Please see Figure 2 , Figure 3 and Figure 7In an embodiment of the present invention, the fixing component 100 further includes a second detection element 120, which is used to contact the skin to detect human information; the patch assembly 200 includes a main board 230 disposed in the patch housing 210 and an electrical connector 240 electrically connected to the main board 230, at least a portion of the electrical connector 240 extending out of the patch housing 210; the second detection element 120 is electrically connected to the main board 230 through the electrical connector 240.
[0063] Understandably, in the embodiment shown in the figures of this invention, the fixing base 110 includes an annular base plate and an annular side plate, the annular side plate being connected to the edge of the annular base plate, and the first limiting groove 111 being disposed on the inner wall of the annular side plate. Thus, when the patch assembly 200 is installed onto the fixing assembly 100, the upper wall of the first limiting boss 211 of the patch assembly 200 abuts against the upper groove wall of the first limiting groove 111, and the bottom wall of the patch assembly 200 abuts against the top wall of the annular base plate, thereby limiting the patch assembly 200 in the vertical direction between the upper groove wall of the first limiting groove 111 and the top wall of the annular base plate, thereby preventing the patch assembly 200 from moving in the vertical direction.
[0064] Understandably, the annular base plate has a detection clearance hole in the middle, and the maximum area that the contact end of the patch assembly 200 can contact with the skin is the area of the detection clearance hole. To increase the contact area and improve detection accuracy and functionality, in one embodiment, a second detection element 120 is also installed on the fixing base 110. The second detection element 120 is installed on the side of the fixing base 110 facing the skin, so that when the smart skin-applying device is applied to the skin, the second detection element 120 can directly contact the skin. More specifically, to avoid interference between the second detection element 120 and the first detection element 220, while ensuring that the second detection element 120 has sufficient mounting support, in one embodiment, the entire projection of the second detection element 120 falls on the annular base plate. In one embodiment, the second detection element 120 is configured as an electrode.
[0065] The surface mount assembly 200 includes a main board 230 and an electrical connector 240. The main board 230 is installed inside the surface mount housing 210, and the electrical connector 240 is electrically connected to the main board 230 and extends out of the surface mount housing 210. When the surface mount assembly 200 and the fixing assembly 100 are connected, one end of the electrical connector 240 extending out of the surface mount housing 210 is electrically connected to the second detection element 120, thereby realizing the electrical connection between the second detection element 120 and the main board 230.
[0066] In an embodiment of the present invention, the fixing component 100 includes an adhesive member 130, one side of which is provided with an adhesive area 131 and a non-adhesive area 132, the non-adhesive area 132 is equipped with a second detection element 120, and the adhesive area 131 is used to adhere to the skin. Alternatively, the fixing component 100 includes an adapter 140, one side of which is provided with an adhesive area 141 and an installation area 142, the second detection component 120 is installed in the installation area 142, the adhesive area 141 is detachably bonded with double-sided adhesive 143, and the other side of the double-sided adhesive 143 is used for bonding with the skin. The fixing component 100 includes a fixing base 110, and a first clearance hole 151 is provided in the non-adhesive area 132 or the mounting area 142. The second detection element 120 is fixed to the fixing base 110 through the first clearance hole 151 so as to clamp the adhesive element 130 or the adapter 140 between the second detection element 120 and the fixing base 110.
[0067] Please see Figure 6 Understandably, in one embodiment, the fixing component 100 is configured as a disposable product. In this case, in the smart skin-applying device, the fixing component 100 can be configured as a plurality of components or a single component. Specifically, the fixing component 100 includes an adhesive member 130, which is generally annular in structure, with a through hole in the center corresponding to and communicating with the detection clearance hole, allowing the first detection element 220 on the patch assembly 200 to pass through. The adhesive member 130 has an adhesive area 131 and a non-adhesive area 132 on the skin-facing side, wherein the non-adhesive area 132 is disposed corresponding to the annular base plate of the fixing seat 110, and the adhesive area 131 is located outside the non-adhesive area 132. A second detection element 120 is installed in the non-adhesive area 132, and the adhesive area 131 has adhesive for bonding with the skin. In one embodiment, at least the adhesive area 131 of the adhesive member 130 is provided with a protective film to prevent the adhesive of the adhesive area 131 from adhering to itself or to other structural components. When using the smart skin-applying device, simply peel off the protective film. The side of the adhesive component 130 facing away from the second detection component 120 is connected to the mounting base 110.
[0068] Please see Figure 7In one embodiment, the fixing component 100 is configured as a reusable product. Specifically, the fixing component 100 includes an adapter 140, which is generally annular in structure and has a through hole in the middle corresponding to and communicating with the detection clearance hole, for the first detection element 220 on the patch assembly 200 to pass through. The adapter 140 has an adhesive area 141 and an installation area 142 on the side facing the skin, wherein the installation area 142 is disposed corresponding to the annular base plate of the fixing seat 110, and the adhesive area 141 is disposed outside the installation area 142. The second detection element 120 is installed in the installation area 142. When using the smart skin-applying device, one side of the double-sided adhesive 143 is adhered to the adhesive area 141, and the other side of the double-sided adhesive 143 is adhered to the skin, thereby fixing the fixing component 100 to the skin. Understandably, in this embodiment, the fixing component 100 is configured as a reusable product, meaning that after the smart skin-applying device completes one cycle of use, the double-sided adhesive 143 can be peeled off from the adhesive area 141. When using the smart skin-applying device again, a new double-sided adhesive 143 can be adhered to the adhesive area 141. Thus, to facilitate the removal of the double-sided adhesive 143 from the adhesive area 141, in one embodiment, the adapter 140 is configured as a non-woven fabric. The side of the adapter 140 facing away from the second detection element 120 is connected to the fixing base 110.
[0069] Understandably, whether using adhesive component 130 or adapter component 140, adhesive component 130 or adapter component 140 is located between the fixing base 110 and the second detection component 120. Specifically, the non-adhesive area 132 of adhesive component 130 or the mounting area 142 of adapter component 140 is provided with a first clearance hole 151. A portion of the second detection component 120 passes through the first clearance hole 151 and connects to the fixing base 110, thereby clamping adhesive component 130 or adapter component 140 between the second detection component 120 and the fixing base 110.
[0070] Please see Figure 3 More specifically, in one embodiment, the second detection element 120 is provided with a mounting rib 121, and the fixing base 110 is provided with a mounting hole (not shown). The mounting rib 121 passes through the first clearance hole 151 and is embedded in the mounting hole so that the second detection element 120 is connected to the fixing base 110.
[0071] Understandably, the second detection element 120 includes a detection body and a mounting rib 121 disposed on the detection body, the mounting rib 121 protruding upward relative to the detection body. Correspondingly, the fixing base 110 is provided with a mounting hole, and the mounting rib 121 passes through the first clearance hole 151 and is embedded in the mounting hole, thereby realizing the connection between the second detection element 120 and the fixing base 110, thereby clamping the adhesive 130 or the adapter 140 between the second detection element 120 and the fixing base 110. In one embodiment, to improve the connection strength between the mounting rib 121 and the mounting hole, adhesive can be applied at the connection position between the mounting rib 121 and the mounting hole. In one embodiment, to improve the connection stability between the second detection element 120 and the fixing base 110, the second detection element 120 is provided with multiple mounting ribs 121, and correspondingly, the adhesive 130 or the adapter 140 is provided with multiple first clearance holes 151.
[0072] Please see Figure 3 and Figure 7 In an embodiment of the present invention, the fixing base 110 is provided with a first through hole 114, the adhesive member 130 or the adapter 140 is provided with a second through hole 152, the electrical connector 240 passes through the first through hole 114 and the second through hole 152 and is electrically connected to the second detection member 120, and the first through hole 114 and the second through hole 152 extend circumferentially along the fixing base 110 so that the electrical connector 240 can move circumferentially within the first through hole 114 and the second through hole 152; and / or, the electrical connector 240 is configured as a telescopic member; and / or, an intermediate conductive member 250 is provided between the electrical connector 240 and the main board 230.
[0073] In one embodiment, the mounting base 110 has a first through hole 114, and the adhesive component 130 or the adapter 140 has a second through hole 152. The second through hole 152 is located in the non-adhesive area 132 or the mounting area 142, that is, the second detection component 120 covers the skin-facing end of the second through hole 152. In one embodiment, the first through hole 114 and the second through hole 152 have the same shape and size. When the patch assembly 200 and the mounting base 110 assembly are connected, the electrical connector 240 passes through the first through hole 114 and the second through hole 152 to contact the second detection component 120, thereby realizing the electrical connection between the electrical connector 240 and the second detection component 120, so that the motherboard 230 and the second detection component 120 are electrically connected through the electrical connector 240.
[0074] Understandably, when the patch assembly 200 is installed onto the fixing assembly 100, it needs to rotate to reach the installed position; when the fixing assembly 100 has multiple stepped positions 113, the patch assembly 200 also needs to rotate to switch between the stepped positions 113. In order to ensure the effectiveness of the electrical connection between the second detection element 120 and the motherboard 230 during the rotation of the electrical connector 240 following the patch assembly 200, in one embodiment, the first through hole 114 and the second through hole 152 both extend circumferentially along the fixing base 110 to have a certain length, that is, the first through hole 114 and the second through hole 152 are configured as elongated holes, so that the electrical connector 240 can move circumferentially within the first through hole 114 and the second through hole 152, while maintaining its electrical connection with the second detection element 120.
[0075] Understandably, when the fixing component 100 has multiple stepped positions 113, the axial distance between the bottom wall of the patch housing 210 and the second detection element 120 is different at different stepped positions 113. To ensure that the electrical connector 240 can be electrically connected to the second detection element 120 at different stepped positions 113, in one embodiment, the electrical connector 240 is configured as a telescopic component. More specifically, in one embodiment, the electrical connector 240 is a POGO-PIN spring.
[0076] Please see Figure 5 and Figure 7 Understandably, the electrical connector 240 contacts the motherboard 230 to achieve electrical connection between the two. To avoid damage to the motherboard 230 by the electrical connector 240, in one embodiment, an intermediate conductive element 250 is provided between the electrical connector 240 and the motherboard 230. In one embodiment, the intermediate conductive element 250 is a flexible conductive element; more specifically, in one embodiment, the intermediate conductive element 250 is configured as conductive foam.
