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, allowing it to adhere closely to the surface of the human skin and achieve non-invasive, continuous acquisition of physiological signals such as heart rate, body temperature, and muscle activity.

[0003] However, existing solutions mostly focus on sensing accuracy or functional integration, and their contact with the skin is usually a fixed design, lacking the ability to actively adjust the contact pressure, thus limiting the application of patch solutions. Summary of the Invention

[0004] The main objective of this invention is to propose an intelligent skin-applying device, which aims to improve the applicability of patch solutions, enable proactive and flexible control of contact pressure, and improve the accuracy of signal acquisition and monitoring.

[0005] To achieve the above objectives, the intelligent skin-applying device proposed in this embodiment of the invention includes: The mounting base includes at least one mounting structure having a plurality of stepped positions for facing the skin; and The patch body has a contact end for contacting the skin, the contact end being provided with an information detection element for contacting the skin to detect human information, the patch body being movably mounted on the fixing base, the patch body including at least one overlapping portion, the contact pressure between the contact end and the skin being different when the overlapping portion overlaps with different stepped positions of the mounting structure.

[0006] In one embodiment, the patch body is rotatable relative to the fixing base, so that the overlapping portion can rotate from one of the stepped positions to another stepped position to adjust the contact pressure between the contact end and the skin.

[0007] In one embodiment, a limiting structure is provided at one of the stepped positions. The limiting structure has a locked state and an unlocked state. In the locked state, the limiting structure is used to restrict the movement of the patch body relative to the fixing seat, so as to restrict the overlapping portion from moving to another stepped position. In the unlocked state, the patch body can move relative to the fixing seat, so that the overlapping portion can move to another stepped position to adjust the contact pressure between the contact end and the skin.

[0008] In one embodiment, the limiting structure is detachably installed on the fixed base. The limiting structure includes a limiting body and a connecting structure that can be unfolded or retracted relative to the limiting body. When the connecting structure is unfolded, it connects to the fixed base to put the limiting structure in an installed state. When the connecting structure is retracted, it separates from the fixed base to put the limiting structure in a disassembled state.

[0009] In one embodiment, the fixing seat has a circumferential abutment, an axial abutment, and a limiting part connected at the stepped position, the axial abutment being oriented toward the skin, and the limiting part having a limiting mounting groove. The limiting structure includes a limiting component and a control component. The limiting component is detachably installed in the limiting mounting slot through the connecting structure, and under the control of the control component, the limiting component can move relative to the limiting mounting slot. When the overlapping portion overlaps the axial abutment portion, the control component can control one end of the limiting component to extend out of the limiting mounting groove, so that the opposite sides of the overlapping portion are limited between the circumferential abutment portion and the limiting component, thereby restricting the movement of the patch body relative to the fixing seat.

[0010] In one embodiment, the limiting portion is inclined relative to the axial abutment portion, and the limiting component includes a limiting block. The limiting block includes a first end and a second end opposite to each other. The first end is movably mounted in the limiting mounting groove, and the second end is hinged to the limiting mounting groove. In the unlocked state, the outer surface of the limiting block does not protrude from the outer surface of the limiting part; in the locked state, the first end extends out of the limiting mounting groove.

[0011] In one embodiment, the limiting component further includes a first elastic member, the two ends of which are respectively connected to the bottom of the limiting block and the limiting mounting groove. The first elastic member is used to make the limiting block tend to be installed in the limiting mounting groove.

[0012] In one embodiment, the limiting block is provided with a receiving space and a receiving opening communicating with the receiving space. The two opposite sides of the second end are provided with first connecting holes communicating with the receiving space. The two opposite side walls of the limiting mounting groove are provided with second connecting holes. The limiting assembly also includes two connecting posts. The two connecting posts are respectively disposed in the two first connecting holes. The two connecting posts are provided with a first inclined surface on the side facing each other. The limiting component further includes a push bar, which is movably installed in the receiving space. One end of the push bar protrudes from the receiving opening and is connected to the first elastic member, while the other end of the push bar faces the second end and is provided with a second inclined surface. When the limiting component is in the installed state, the angle between the first elastic element and the second end of the limiting block is set at an acute angle. Under the pulling force of the first elastic element, the other end of the push bar moves towards the second end, and the second inclined surface pushes against the two first inclined surfaces, so that the two connecting posts extend out of the two first connecting holes and into the two second connecting holes respectively. When the limiting component is in the disassembled state, the outer surfaces of the two connecting posts do not protrude from the opposite side walls of the limiting block.

[0013] In one embodiment, a first magnet is installed at one end of the push bar facing the connecting post, and a second magnet is provided on each of the two first inclined surfaces; in the direction from one of the connecting posts to the other, the opposite sides of the first magnet are attracted to the two second magnets respectively.

[0014] In one embodiment, the axial abutment portion is provided with a control mounting groove that communicates with the limiting mounting groove, and the control component includes a rocker arm that is oscillatingly mounted in the control mounting groove. The rocker arm includes a supporting end and a limiting end that are disposed opposite to each other. In the unlocked state, the abutting end protrudes from the opening of the control mounting groove, the limiting end contacts the inner wall of the limiting component, and the limiting component is installed in the limiting mounting groove; in the locked state, the abutting end does not protrude from the opening of the control mounting groove, and the limiting end abuts against the inner wall of the limiting component, so that the limiting component extends out of the limiting mounting groove.

[0015] In one embodiment, a third magnet is installed on the axial abutment portion, and a fourth magnet is installed on the side of the overlapping portion away from the skin, and the third magnet and the fourth magnet are attracted to each other.

[0016] In one embodiment, the fixing base is provided with a disassembly port, the disassembly port is connected to the step position, and the overlapping part overlaps with the step position or separates from the fixing base through the disassembly port; And / or, the contact end is equipped with a pressure detection element, which is used to detect the pressure value of the contact pressure.

[0017] The technical solution of this invention involves setting a fixing base and a patch body in a smart skin-applying device. The fixing base includes at least one mounting structure with multiple stepped positions facing the skin. The patch body has a contact end for contacting the skin, and the contact end is equipped with an information detection element for contacting the skin to detect human information. The patch body is movably mounted on the fixing base and includes at least one overlapping portion. When the overlapping portion overlaps with different stepped positions of the mounting structure, the contact pressure between the contact end and the skin varies. Thus, this invention provides multiple stepped positions in the fixing base of the smart skin-applying device. By overlapping the patch body with different stepped positions, different contact pressures are achieved between the smart skin-applying device and the skin, enabling active and flexible control of the contact pressure. This improves the accuracy of signal acquisition and monitoring, thereby meeting the needs of different users and different detection projects. The smart skin-applying device provided by this application has a wide range of applications. Attached Figure Description

[0021] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0023] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0024] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0025] 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, allowing it to adhere closely to the skin surface and achieve non-invasive, continuous acquisition of physiological signals such as heart rate, body temperature, and muscle activity. For example, some devices analyze skin condition using color sensors or detect electrophysiological signals using electrodes, and leverage algorithms to provide personalized care plans.

[0026] However, existing solutions mostly focus on sensing accuracy or functional integration, and their contact with the skin is usually a fixed design, lacking the ability to actively adjust the contact pressure, thus limiting the application of patch solutions.

[0027] For example, in medical monitoring, different detection targets (such as superficial capillary blood flow and deep tissue temperature) require different contact pressures to ensure signal accuracy; in the beauty field, the penetration efficiency of skincare ingredients is also affected by patch pressure. More importantly, individual differences in users' skin contours (such as joints and facial contours) require devices to have local adaptive fitting capabilities, while rigid or single-level designs can easily lead to measurement errors, decreased comfort, and even signal interruption.

[0028] In view of this, the present invention proposes an intelligent skin-applying device.

[0029] Please see Figure 1 and Figure 2In one embodiment of the present invention, the smart skin-applying device includes a fixing base 100 and an applicator body 200. The fixing base 100 includes at least one mounting structure 110, which has multiple stepped positions 111 facing the skin. The applicator body 200 has a contact end 210 for contacting the skin, and the contact end 210 is provided with an information detection element 211 for contacting the skin to detect human information. The applicator body 200 is movably mounted on the fixing base 100. The applicator body 200 includes at least one overlapping portion 220. When the overlapping portion 220 overlaps with different stepped positions 111 of the mounting structure 110, the contact pressure between the contact end 210 and the skin is different.

[0030] Understandably, smart skin-mounted devices are worn on the human body. Through the contact of the information detection element 211 within the device with the skin, they collect or monitor human information data. Specifically, they can be fixed to the body using methods such as adhesive tape. Of course, with the development of smart skin-mounted devices, they can also be applied in the animal field to assist in animal medicine, animal health, and animal experiments.

[0031] The intelligent skin-applying device includes a movable mounting base 100 and a patch body 200. The patch body 200 has a contact end 210 facing the skin, and the contact end 210 is equipped with an information detection element 211 for contact with the skin. The information detection element 211 can be used to detect information such as heart rate, respiratory rate, and skin moisture content. The information detection element 211 can be an electrode, an electrocardiogram sensor, an optical heart rate / blood oxygen sensor, etc., and the type and number of information detection elements 211 are not limited here. To facilitate the connection between the patch body 200 and the mounting base 100, the patch body 200 is provided with an overlapping portion 220. In the embodiment shown in the figures of this invention, the overlapping portion 220 is configured as an outwardly protruding overlapping ear, which is generally cubic or cuboid in shape. The specific structure of the overlapping portion 220 is not limited here.

[0032] Understandably, the mounting base has at least one mounting structure 110, and correspondingly, the patch body 200 has at least one overlapping portion 220. When the patch body 200 and the mounting base 100 are connected, one overlapping portion 220 overlaps one mounting structure 110. In one embodiment, the number and position of the mounting structures 110 correspond one-to-one with the overlapping portions 220. Of course, the number of mounting structures 110 can be more than the number of overlapping portions 220, or the number of mounting structures 110 can be twice the number of overlapping portions 220, so that even if individual mounting structures 110 are damaged, the patch body 200 and the mounting base 100 can still be connected and used.

[0033] An installation structure 110 is provided with multiple stepped positions 111. Each of the multiple stepped positions 111 is at a different height from the skin. This results in different contact pressures between the patch body 200 and the skin when it overlaps with different stepped positions 111, thus meeting the needs of different users and different testing projects, thereby improving the applicability of the intelligent skin-applying device.

[0034] Understandably, the arrangement of multiple stepped contact points 111 allows the smart skin-applying device to have multiple different contact levels, each with a different contact pressure. To facilitate switching between these contact levels, the multiple stepped contact points 111 are arranged adjacent to each other. In the solution shown in the figures of this invention, as... Figure 3 As shown, an installation structure 110 has two step positions 111. Of course, the number of step positions 111 can also be three or other numbers, and there is no limit to the number of step positions 111 here.

[0035] Each of the multiple stepped positions 111 is oriented towards the skin, meaning that the stepped position 111 abuts against the side of the overlapping portion 220 that is away from the skin. It is understood that in the embodiment shown in the figures of this invention, there is no fixed connection between the fixing base 100 and the patch body 200; the assembly of the smart skin-applying device is achieved through the contact between the stepped positions 111 and the patch body 200. When the patch body 200 and the fixing base 100 are assembled together and placed on the skin, the upper and lower limits of the patch body 200 are respectively achieved through the stepped positions 111 and the skin.

[0036] The technical solution of this invention involves setting a fixing base 100 and a patch body 200 in a smart skin-applying device. The fixing base 100 includes at least one mounting structure 110, which has multiple stepped positions 111 facing the skin. The patch body 200 has a contact end 210 for contacting the skin, and the contact end 210 is provided with an information detection element 211 for contacting the skin to detect human information. The patch body 200 is movably mounted on the fixing base 100 and includes at least one overlapping portion 220. When the overlapping portion 220 overlaps with different stepped positions 111 of the mounting structure 110, the contact pressure between the contact end 210 and the skin is different. Thus, the present invention provides multiple stepped positions 111 in the fixing base 100 of the intelligent skin-applying device. By overlapping the overlapping part 220 of the patch body 200 with different stepped positions 111, 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.

[0037] Please see Figure 2 and Figure 3 In an embodiment of the present invention, the patch body 200 can rotate relative to the fixing base 100 so that the overlapping portion 220 can rotate from one step position 111 to another step position 111 to adjust the contact pressure between the contact end 210 and the skin.

[0038] Understandably, the external shape of a smart skin-applying device can be circular, rectangular, or other irregularly shaped to suit different body parts or meet the needs of different users. Therefore, no restrictions are placed on the shape of the smart skin-applying device.

[0039] In the embodiment shown in the figures of this invention, the patch body 200 is generally cylindrical, and correspondingly, the fixing seat 100 is generally annular. The fixing seat 100 is sleeved on the patch body 200, thereby achieving the connection between the two. It is understood that the fixing seat 100 can be a closed annulus or an annular structure with an opening; the specific shape of the fixing seat 100 is not limited herein.

[0040] Thus, by configuring the patch body 200 to rotate relative to the fixed base 100, when the smart skin-applying device needs to switch contact levels, simply rotating the patch body 200 circumferentially is sufficient to switch contact levels, which improves ease of operation. Of course, in other embodiments, the smart skin-applying device can also be rectangular; correspondingly, the patch body 200 can move along its length relative to the fixed base 100 to achieve contact level switching. The following description uses the rotation of the patch body 200 relative to the fixed base 100 to switch contact levels as an example.

[0041] Please see Figure 4 In an embodiment of the present invention, a limiting structure 300 is provided at a step 111. The limiting structure 300 has a locked state and an unlocked state. In the locked state, the limiting structure 300 is used to restrict the movement of the patch body 200 relative to the fixing base 100, so as to restrict the overlapping part 220 from moving to another step 111. In the unlocked state, the patch body 200 can move relative to the fixing base 100, so that the overlapping part 220 can move to another step 111 to adjust the contact pressure between the contact end 210 and the skin.

[0042] Understandably, when the smart skin-applying device is in use, the overlapping part 220 overlaps with a step 111. To prevent the smart skin-applying device from switching between different positions during use and to ensure the accuracy of the detection results, the smart skin-applying device is also equipped with a limiting structure 300. Specifically, a limiting structure 300 is provided at each step 111, which is used to restrict the overlapping part 220 from moving from one step 111 to another. In one embodiment, the patch body 200 rotates relative to the fixed base 100, allowing the overlapping part 220 to switch between different step positions 111. Correspondingly, when the limiting structure 300 is in the locked state, it can restrict the circumferential rotation of the patch body 200. When the limiting structure 300 is in the unlocked state, the patch body 200 can rotate circumferentially.

[0043] In an embodiment of the present invention, the limiting structure 300 is detachably installed on the fixed base 200. The limiting structure 300 includes a limiting body and a connecting structure that can be unfolded or retracted relative to the limiting body. When the connecting structure is unfolded, it connects to the fixed base 200 so that the limiting structure 300 is in the installed state. When the connecting structure is retracted, it separates from the fixed base 200 so that the limiting structure is in the disassembled state.

[0044] Understandably, the limiting structure 300 is detachably installed on the fixing base 200, which facilitates the installation and replacement of the limiting structure 300. In one embodiment, the limiting structure 300 includes a limiting body and a connecting structure. The connecting structure can be unfolded or retracted relative to the limiting body. The limiting body is detachably connected to the fixing base 200 through the connecting structure. The limiting body is used to limit or unlock the overlapping portion 220.

[0045] When the limiting structure 300 needs to be installed onto the fixed base 200, the connecting structure unfolds relative to the limiting body, connecting the connecting structure to the fixed base 200. When the limiting structure 300 needs to be removed from the fixed base 200, the connecting structure retracts relative to the limiting body, separating the connecting structure from the fixed base 200, thus enabling the disassembly of the limiting structure 300. In this way, by designing the connecting structure to unfold or retract relative to the limiting body, quick installation and disassembly of the limiting structure 300 relative to the fixed base 200 are achieved, improving the convenience and efficiency of the detachable installation and disassembly of the limiting structure 300 relative to the fixed base 200.

[0046] Please see Figures 3 to 5In an embodiment of the present invention, the fixing base 100 has a circumferential abutment portion 120, an axial abutment portion 130 and a limiting portion 140 connected at the stepped position 111. The axial abutment portion 130 is directed toward the skin, and the limiting portion 140 has a limiting mounting groove 141. The limiting structure 300 includes a limiting component 400 and a control component 500. The limiting component 400 is detachably mounted to the limiting mounting groove 141 through a connecting structure, and under the control of the control component 500, the limiting component 400 can move relative to the limiting mounting groove 141. When the overlapping portion 220 overlaps with the axial abutment portion 130, the control component 500 can control one end of the limiting component 400 to extend out of the limiting mounting groove 141, so that the opposite sides of the overlapping portion 220 are limited between the circumferential abutment portion 120 and the limiting component 400, thereby restricting the movement of the patch body 200 relative to the fixing seat 100.

[0047] Understandable, such as Figure 3 As shown, the fixing base 100 has a circumferential abutment portion 120, an axial abutment portion 130, and a limiting portion 140 connected in sequence at the stepped position 111, wherein the circumferential abutment portion 120 and the axial abutment portion 130 are arranged at an included angle. In the embodiment shown in the figures of the present invention, the included angle between the two is approximately 90°. Of course, the included angle between the two can also be an obtuse angle or an acute angle, as long as the circumferential abutment portion 120 can contact one side wall of the overlapping portion 220 after the overlapping portion 220 overlaps the axial abutment portion 130. The axial abutment portion 130 is oriented towards the skin, that is, when the smart skin-adhesive device is used, the axial abutment portion 130 is face-to-face with the skin. Figure 5 As shown, when the overlapping portion 220 overlaps the axial abutment portion 130, the axial abutment portion 130 restricts the overlapping portion 220 from moving away from the skin, thereby restricting the patch body 200 from moving away from the skin and ensuring that the contact end 210 on the patch body 200 can maintain contact with the skin during use of the smart skin-applying device. In one embodiment, the axial abutment portion 130 extends in a horizontal direction, thus ensuring the contact area between the axial abutment portion 130 and the overlapping portion 220. Of course, the axial abutment portion 130 can also have other structural shapes, as long as the axial abutment portion 130 can contact the overlapping portion 220 and restrict the overlapping portion 220 from moving away from the skin.

[0048] like Figure 4As shown, the limiting structure 300 includes a limiting component 400 and a control component 500. The limiting part 140 at the stepped position 111 is provided with a limiting mounting groove 141. The limiting component 400 is installed in the limiting mounting groove 141, and the control component 500 is used to control the movement of the limiting component 400 relative to the limiting mounting groove 141. When the contact level of the smart skin-applying device is adjusted, the overlapping part 220 overlaps with the axial abutment part 130. The control component 500 controls one end of the limiting component 400 to extend out of the limiting mounting groove 141, thereby limiting the circumferentially opposite sides of the overlapping part 220 between the circumferential abutment part 120 and the limiting component 400 extending out of the limiting mounting groove 141. This restricts the circumferential rotation of the overlapping part 220, restricts the rotation of the patch body 200 relative to the fixed base 100, and restricts the switching of the contact level of the smart skin-applying device. When it is necessary to switch the contact position, the control component 500 controls the limit component 400 to fall back into the limit mounting groove 141, or the control component 500 stops working, causing the limit component 400 to fall back into the limit mounting groove 141, thereby causing the side of the overlapping part 220 away from the circumferential abutment part 120 to lose its abutment. At this time, the patch body 200 can be rotated in the direction away from the circumferential abutment part 120 of the step position 111, thereby rotating the overlapping part 220 to another step position 111, thereby realizing the switching of the contact position.

[0049] It is understandable that the control component 500 can be either a mechanical control structure or an electric control structure, and no restriction is made here.

[0050] Understandably, from the perspective of the limiting structure 300 having a locked state and an unlocked state, the limiting structure 300 may include a limiting component 400 and a control component 500. From the perspective of the limiting structure 300 having an installed state and a disassembled state, the limiting structure 300 may include a limiting body and a connecting structure. That is, the limiting body includes part of the limiting component 400 and the control component 500, and the connecting structure includes part of the limiting component 400. In one embodiment, the connecting structure includes the first elastic member 420, the connecting post 430, etc. mentioned below, and the limiting body includes the limiting block 410, etc. mentioned below. For ease of explanation, the limiting structure 300 will be described below from the perspective that the limiting structure 300 includes the limiting component 400 and the control component 500.

[0051] Please see Figure 4 and Figure 5In an embodiment of the present invention, the limiting part 140 is inclined relative to the axial abutment part 130, and the limiting component 400 includes a limiting block 410. The limiting block 410 includes a first end 411 and a second end 412 opposite to each other. The first end 411 is movably mounted in the limiting mounting groove 141, and the second end 412 is hinged to the limiting mounting groove 141. In the unlocked state, the outer surface of the limiting block 410 does not protrude from the outer surface of the limiting part 140. In the locked state, the first end 411 extends out of the limiting mounting groove 141.

[0052] Understandably, in the embodiment shown in the figures of this invention, the limiting portion 140 is inclined. Specifically, in the direction of the limiting portion 140 near the axial abutment portion 130, the limiting portion 140 is inclined towards the skin. Understandably, the inclined arrangement of the limiting portion 140 facilitates the switching of contact levels of the smart skin-applying device.

[0053] The limiting assembly 400 includes a limiting block 410. The first end 411 of the limiting block 410 is movably mounted in the limiting mounting groove 141 and positioned near the axial abutment portion 130. The second end 412 of the limiting block 410 is hinged to the limiting mounting groove 141. Figure 4 As shown, when the limiting structure 300 is in the unlocked state, the outer surface of the limiting block 410 does not protrude from the outer surface of the limiting portion 140. That is, the outer surface of the limiting block 410 does not protrude from the plane where the opening of the limiting mounting groove 141 is located. In the embodiment shown in the figures of this invention, in the unlocked state, the outer surface of the limiting block 410 is flush with the plane where the opening of the limiting mounting groove 141 is located. Figure 5 As shown, when the limiting structure 300 is in the locked state, the control component 500 controls the first end 411 of the limiting block 410 to extend out of the limiting mounting groove 141. At this time, the second end 412 rotates relative to the limiting mounting groove 141, so that the first end 411 protrudes out of the limiting part 140 and can contact one side wall of the overlapping part 220, thereby restricting the circumferential rotation of the overlapping part 220.

[0054] Of course, in other embodiments, the limiting part 140 may also be arranged in the horizontal direction, and the limiting component 400 may be a telescopic limiting rod, wherein the limiting rod may extend or retract in the vertical direction to the limiting mounting groove 141 under the control of the control component 500, thereby locking or unlocking the overlapping part 220 in the circumferential direction.

[0055] Please see Figure 4 and Figure 5 In an embodiment of the present invention, the limiting component 400 further includes a first elastic member 420, the two ends of which are respectively connected to the limiting block 410 and the bottom of the limiting mounting groove 141. The first elastic member 420 is used to make the limiting block 410 tend to be installed in the limiting mounting groove 141.

[0056] Understandably, in one embodiment, the limiting component 400 further includes a first elastic member 420. One end of the first elastic member 420 is connected to the bottom of the limiting mounting groove 141, and the other end of the first elastic member 420 is connected to the portion between the first end 411 and the second end 412 of the limiting block 410. This causes the limiting block 410 to tend to be installed in the limiting mounting groove 141, thereby causing the limiting structure 300 to tend to be in an unlocked state. Thus, the provision of the first elastic member 420 facilitates the switching of the limiting structure 300 from a locked state to an unlocked state.

[0057] In one embodiment, the first elastic element 420 is configured as a tension spring. When in the unlocked state, the tension spring is still slightly stretched, so that the limiting block 410 can be stably installed in the limiting mounting groove 141, which is beneficial to maintaining the unlocked state.

[0058] Please see Figure 6 and Figure 7 In an embodiment of the present invention, the limiting block 410 is provided with a receiving space 414 and a receiving opening 415 communicating with the receiving space 414. The two opposite sides of the second end 412 are provided with first connecting holes 413 communicating with the receiving space 414. The two opposite side walls of the limiting mounting groove 141 are provided with second connecting holes. The limiting component 400 also includes two connecting posts 430. The two connecting posts 430 are respectively provided in the two first connecting holes 413. The side of the two connecting posts 430 facing each other is provided with a first inclined surface 431. The limiting component 400 also includes a push bar 440, which is movably installed in the receiving space 414. One end of the push bar 440 protrudes from the receiving opening 415 and is connected to a first elastic member 420. The other end of the push bar 440 is set towards the second end 412 and is provided with a second inclined surface 441. When the limiting component 400 is in the installed state, the angle between the first elastic element 420 and the second end 412 of the limiting block 410 is set at an acute angle. Under the pulling force of the first elastic element 420, the other end of the push bar 440 moves towards the second end 412, and the second inclined surface 441 pushes against the two first inclined surfaces 431, so that the two connecting posts 430 extend out of the two first connecting holes 413 and into the two second connecting holes respectively. When the limiting component 400 is in the disassembled state, the outer surfaces of the two connecting posts 430 do not protrude from the opposite side walls of the limiting block 410.

[0059] Understandably, in one embodiment, at least the limiting component 400 in the limiting structure 300 is detachably installed in the limiting part 140, thereby facilitating the installation and replacement of the limiting component 400. Specifically, the limiting block 410 is provided with a receiving space 414 and a receiving opening 415, the receiving opening 415 being connected to the receiving space 414. First connecting holes 413 are provided on opposite sides of the second end 412 of the limiting block 410, and second connecting holes are provided on opposite side walls of the limiting mounting groove 141. The limiting component 400 also includes two connecting posts 430, each disposed in one of the two first connecting holes 413, the two first connecting holes 413 being connected to the receiving space 414. Simultaneously, each of the two connecting posts 430 has a first inclined surface 431 on the side facing each other. The limiting component 400 also includes a pusher 440, which is movably installed in the receiving space 414 through the receiving opening 415 and is movable relative to the receiving space 414. One end of the push bar 440 protrudes from the receiving opening 415, and this end of the push bar 440 is provided with a connecting hook for connecting with the first elastic member 420. The other end of the push bar 440 is positioned towards the second end 412, and each of the opposite sides of this end is provided with a second inclined surface 441 to cooperate with the first inclined surface 431 of the two connecting posts 430 respectively.

[0060] When installing the limiting component 400, first install the two connecting posts 430 into the receiving space 414 through the two first connecting holes 413, and then install the push bar 440 into the receiving space 414 through the receiving opening 415. At this time, the two connecting posts 430 do not protrude from the two first connecting holes 413. Then connect the first elastic member 420 to the push bar 440. Next, align the two first connecting holes 413 of the limiting block 410 with the two second connecting holes in the limiting mounting groove 141. Then connect the other end of the first elastic member 420 to the connecting hook at the bottom of the limiting mounting groove 141. At this time, the included angle between the first elastic element 420 and the push bar 440 is an acute angle, and the first elastic element 420 is in a stretched state. Under the elastic force of the first elastic element 420, the push bar 440 moves towards the second end 412, thereby causing the two second inclined surfaces 441 of the push bar 440 to push against the first inclined surfaces 431 of the two connecting posts 430, thereby extending the connecting post 430 out of the first connecting hole 413 and into the second connecting hole, thus locking the connecting post 430 into the second connecting hole, thereby realizing the connection and fixation of the limiting component 400 and the limiting mounting groove 141. Of course, during the installation process, the first elastic element 420 can also be connected to the limiting mounting groove 141 first, and after the first connecting hole 413 and the second connecting hole are aligned, the other end of the first elastic element 420 can be connected to the push bar 440.

[0061] In the disassembled state, the outer surfaces of the two connecting posts 430 do not protrude from the opposite side walls of the limiting block 410. First, force is applied to the first end 411, causing the first end 411 to disengage from the limiting mounting groove 141 and lift up. Then, the first elastic member 420 is separated from the limiting mounting groove 141, or the first elastic member 420 is separated from the push bar 440. Thus, with the push bar 440 losing its ability to move towards the second end 412, the two connecting posts 430 lose their force to extend out of the first connecting hole 413. The two connecting posts 430 switch to a state where their outer surfaces do not protrude from the opposite side walls of the limiting block 410. At this point, the limiting assembly 400 can be removed from the limiting mounting groove 141.

[0062] Please see Figure 7 and Figure 8 In an embodiment of the present invention, a first magnet 442 is installed on one end of the push bar 440 facing the connecting post 430, and a second magnet 432 is provided on both first inclined surfaces 431; in the direction from one connecting post 430 to the other connecting post 430, the opposite sides of the first magnet 442 are attracted to the two second magnets 432 respectively.

[0063] Understandably, the push bar 440 has a first magnet 442 between the two second inclined surfaces 441, and a second magnet 432 is provided on each of the two first inclined surfaces 431. The two second magnets 432, the first magnet 442, and the other second magnet 432 are in an attractive relationship. Thus, when the limiting assembly 400 is removed from the limiting mounting groove 141, after the push bar 440 loses the force of the first elastic element 420, it moves towards the first end 411. The two second magnets 432 attract each other under magnetic force, allowing the two connecting posts 430 to retract from the second connecting hole into the receiving space 414. When the two second magnets 432 are in contact, the outer surfaces of the two connecting posts 430 do not protrude from the opposite side walls of the limiting block 410.

[0064] Of course, in other embodiments, a first electromagnet can be provided on the side of the two connecting posts 430 away from each other, and a second electromagnet can be provided at the bottom of the second connecting hole. By controlling the polarities of the first and second electromagnets, and utilizing the principle of opposite poles attracting and like poles repelling, the connecting post 430 can be controlled to extend into the second connecting hole or retract into the receiving space 414.

[0065] Please see Figure 4 and Figure 5 In an embodiment of the present invention, the axial abutment portion 130 is provided with a control mounting groove 131 that communicates with the limiting mounting groove 141. The control component 500 includes a rocker arm 510, which is oscillatingly mounted in the control mounting groove 131. The rocker arm 510 includes a supporting end 511 and a limiting end 512 that are disposed opposite to each other. In the unlocked state, the supporting end 511 protrudes from the opening of the control mounting groove 131, the limiting end 512 contacts the inner wall of the limiting component 400, and the limiting component 400 is installed in the limiting mounting groove 141; in the locked state, the supporting end 511 does not protrude from the opening of the control mounting groove 131, and the limiting end 512 abuts against the inner wall of the limiting component 400, so that the limiting component 400 extends out of the limiting mounting groove 141.

[0066] Understandably, in the embodiment shown in the figures of this invention, the control component 500 includes a rocker arm 510, and an axial abutment portion 130 is provided with a control mounting groove 131. The control mounting groove 131 is connected to a limiting mounting groove 141, and the rocker arm 510 is oscillatingly mounted within the control mounting groove 131. In one embodiment, the rocker arm 510 is generally U-shaped, with its two ends being an abutment end 511 and a limiting end 512, respectively. The rocker arm 510 has a swing connection portion between the abutment end 511 and the limiting end 512, and a first swing connection hole is provided at the swing connection portion. A second swing connection hole is provided within the control mounting groove 131, and a swing connection shaft passes through the first swing connection hole, thereby connecting the rocker arm 510 to the swing connection shaft. Simultaneously, both ends of the swing connection shaft extend into the two second swing connection holes, thereby oscillatingly mounting the rocker arm 510 within the control mounting groove 131.

[0067] In one embodiment, a second swing connection hole is provided through the rocker arm 510, so that the swing connection shaft can be detachably connected to the fixed base 100, thereby realizing the detachable connection of the rocker arm 510.

[0068] The abutting end 511 of the rocker arm 510 is disposed near the circumferential abutting portion 120, and the limiting end 512 is disposed near the limiting portion 140. In the embodiment shown in the figures of the present invention, the abutting end 511 is higher than the limiting end 512, and the limiting end 512 is used to contact the inner wall of the first end 411 of the limiting block 410.

[0069] When the contact level of the smart skin-applying device is adjusted to the correct position, the overlapping portion 220 abuts against the axial abutment portion 130 of the stepped position 111. Under the upward reaction force of the skin acting on the patch body 200, the overlapping portion 220 pushes upward against the abutment end 511 of the rocker arm 510, causing the rocker arm 510 to swing with the abutment end 511 upward and the limiting end 512 downward. During the downward movement of the limiting end 512, the first end 411 of the limiting end 512 abutting against the limiting block 410 pops out from the limiting mounting groove 141, thereby achieving circumferential limiting of the overlapping portion 220.

[0070] When the smart skin-applying device needs to switch contact levels, a downward force is applied to the patch body 200, causing the patch body 200 to move toward the skin. This separates the overlapping portion 220 from the axial abutment portion 130, causing the abutment end 511 of the rocker arm 510 to lose its upward force. Under the elastic force of the first elastic element 420, the second end 412 retracts upward into the limiting mounting groove 141, thereby pushing the limiting end 512 upward. This causes the rocker arm 510 to swing with the limiting end 512 upward and the abutment end 511 downward. At this time, the abutment end 511 protrudes from the plane where the groove of the control mounting groove 131 is located, and the overlapping portion 220 is released from circumferential restriction. The contact level can be switched by rotating the patch body 200.

[0071] It is important to note that "up" refers to the direction away from the skin, while "down" refers to the direction closer to the skin.

[0072] Please see Figure 5 In an embodiment of the present invention, a third magnet 132 is installed on the axial abutment portion 130, and a fourth magnet 221 is installed on the side of the overlapping portion 220 away from the skin. The third magnet 132 and the fourth magnet 221 are attracted to each other.

[0073] Understandably, the axial abutment portion 130 has a third magnet 132 installed near the control mounting groove 131, and the overlapping portion 220 has a fourth magnet 221 installed on the side facing away from the skin. When the overlapping portion 220 overlaps with the axial abutment portion 130, the third magnet 132 and the fourth magnet 221 attract each other. Understandably, the arrangement of the third magnet 132 and the fourth magnet 221 is beneficial for guiding and ensuring the accuracy of the overlap between the overlapping portion 220 and the axial abutment portion 130.

[0074] Understandably, when the smart skin-adhesive device switches contact levels, the pressure applied to the skin-facing end of the patch body 200 is much greater than the adsorption force between the third magnet 132 and the fourth magnet 221. In other words, the adsorption of the third magnet 132 and the fourth magnet 221 will not affect the switching of contact levels.

[0075] Please see Figure 1 and Figure 2 In an embodiment of the present invention, the fixed base 100 is provided with a disassembly port 150, which is connected to the step position 111. The overlapping part 220 overlaps with the step position 111 or separates from the fixed base 100 through the disassembly port 150. And / or, a pressure sensing element 212 is installed on the contact end 210, which is used to detect the pressure value of the contact pressure.

[0076] It is understood that, in one embodiment, as Figure 1 and Figure 2As shown, the mounting base 100 is provided with a disassembly port 150, which communicates with the stepped position 111. In the embodiment shown in the figures of this invention, the disassembly port 150 is connected to the stepped position 111 with the least contact pressure. That is, axially, the disassembly port 150 extends to the end of the mounting base 100 facing away from the skin. Thus, the disassembly port 150 facilitates the overlap or separation of the patch body 200 and the mounting base 100.

[0077] In one embodiment, such as Figure 2 As shown, the contact end 210 of the patch body 200 is also equipped with a pressure detection element 212. The pressure detection element 212 is electrically connected to the main controller of the smart skin-applying device. The pressure detection element 212 is used to detect the pressure value of the contact pressure, and the main controller is used to receive the pressure value. In one embodiment, the smart skin-applying device also has a display component or can be electrically connected to an external display device. The main controller displays the received pressure value on the display component, and the user judges whether the contact level is appropriate by reading the pressure value. The pressure detection element 212 can be a pressure sensor, etc. The external display device can be a mobile phone, tablet, etc.

[0078] The above description is merely an exemplary embodiment of the present invention and does not limit the scope of protection of the present invention. Any equivalent structural transformations made based on the technical concept of the present invention and the contents of the specification and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present invention.
