Description

Technical Field

[0001] The invention relates to the technical field of human neck massage, in particular to a neck massage patch and a patch manufacturing method. Background Art

[0002] A neck massager that is portable and can be worn around the neck has gradually become popular in recent years. It uses bioelectric current to stimulate the neck nerves to massage the muscles of the human neck, thereby relieving the user's fatigue after long hours of work. Neck massagers currently use patches to contact the skin of the human neck. In order to avoid the cold discomfort caused by the temperature difference between the patch and the skin when it is first used, a heating device is provided in the patch. The heat generated by the heating device to the contact electrode is easily affected by the interval changes in the process, resulting in non-uniform heating.

[0003] Guangdong Aishikaiqi Intelligent Technology Co., Ltd. has developed and proposed a neck massager and a temperature detection method thereof. The relevant technology is disclosed in the invention patents CN111558144A and CN111558153A. The neck massager includes a massager body, a heating element, a temperature detection element, and a control circuit. The heating element is arranged on the massager body for heating the human neck; the temperature detection element is arranged on the massager body for detecting the temperature of the human neck; the control circuit is arranged on the massager body and electrically coupled to the heating element and the temperature detection element, and is used to respond to the condition that the heating element is not in a working state, and control the temperature detection element to detect the temperature of the human neck, so as to obtain the body temperature of the wearer of the neck massager in a natural state. Alternatively, the neck massager includes: a massager body, a temperature detection element, a communication circuit, and a control circuit. The temperature detection element is arranged on the massager body to detect the temperature of the human neck; the communication circuit is arranged on the massager body; the control circuit is arranged on the massager body and electrically coupled to the communication circuit and the temperature detection element to control the temperature detection element to detect the temperature of the human neck and control the communication circuit to send out the data corresponding to the temperature of the human neck. The electrode sheet used in the massager body is a massage patch, which is a consumable material of the neck massager.

[0004] As a supplier of joint R&D of the product ecosystem, it is necessary for the applicant to develop a massage patch that can be adapted to related neck massagers of the same type, which can simultaneously perform the functions of neck massage contact and patch preheating before neck contact. Traditionally, the exposed external connection ends of contact circuit patches are prone to collision and cause signal short circuit problems. When in use, the humidity under the contact between the patch and the human neck is also likely to cause signal interference between the heating drive circuit and the massage electrode, resulting in reduced durability of the patch. Summary of the invention

[0005] The main purpose of the present invention is to provide a neck massage patch. The main improvement is to solve the above-mentioned problems, prevent the humidity when the patch contacts the human neck from interfering with the signal transmission of the patch to the neck massager, and prevent the exposed external connection end from easily colliding and causing signal short circuit, and can simultaneously play the role of neck massage contact and uniform heating.

[0006] The second main purpose of the present invention is to provide a patch manufacturing method to achieve the requirements of standardized mass production of neck massage patches and consumable materials with stable quality.

[0007] The main purpose of the present invention is achieved through the following technical solutions:

[0008] A neck massage patch is provided, comprising:

[0009] A first insulating base film, wherein a massage electrode is disposed on a contact surface of the first insulating base film, and an interconnection line electrically connected to the massage electrode is disposed on a pressing surface of the first insulating base film;

[0010] A second insulating base film is arranged on the pressed surface of the first insulating base film, a massage driving circuit and a heating driving circuit are formed on the surface of the second insulating base film, and an external film portion is integrally formed in the second insulating base film, the massage driving circuit is electrically connected to the interconnection line, and the heating driving circuit includes a heating electrode and two side wirings alternately connected to the heating electrode;

[0011] a graphene heating layer, formed on the second insulating base film and covering the heating electrode connected to the heating driving circuit;

[0012] Among them, the first terminal point electrically connected to the heating drive circuit and the second terminal point electrically connected to the massage drive circuit are aligned and arranged on the plug-in side of the external film part, and the external film part can be tilted away from the first insulating base film.

[0013] By adopting the above technical scheme, the first insulating base film provided with massage electrodes and the second insulating base film for forming the graphene heating layer are overlapped to form a massage patch with a preheating function, and the massage driving circuit in the second insulating base film that may interfere with the heating driving circuit is separated and designed to be the interconnection line of the first insulating base film, so that the main circuit of the massage driving circuit can be configured on the second insulating base film on the same configuration surface as the heating driving circuit, and the formation of the graphene heating layer does not interfere with the interconnection line and the massage electrode of the first insulating base film under the isolation of the second insulating base film. In addition, the external film portion is formed integrally in the second insulating base film, and does not interfere with the interconnection line and the massage electrode of the first insulating base film. The external connection end of the massage electrode patch is secretive and easy to make. The heating driving circuit and the massage electrode are separated by at least the first insulating base film and the second insulating base film. The heating electrodes are alternately connected by the two-side wiring of the heating driving circuit, so that the heating electrodes are comb-shaped connection structures, and the connection points of the two-side wiring of the specific heating electrode pair are arranged in a Z-shaped manner. The same block of the graphene heating layer can be isolated by the position of the heating electrode and can also be divided into multiple compact heating areas.

[0014] In a preferred structural example, the present invention may be further configured as follows: the plug-in side of the external film portion and the adjacent side edges adjacent to the plug-in side are surrounded by continuously extending slots, and the pattern of the slots overlaps the first insulating base film.

[0015] By adopting the above preferred technical features, the second insulating base film can be used to have a groove with a pattern overlapping on the first insulating base film to surround and form an external film portion, and the external film portion in the electrode patch is spaced from the edge of the first insulating base film. When not warped, the external film portion can be hidden in the second insulating base film and does not extend to the edge of the electrode patch, which has better moisture resistance.

[0016] In a preferred structural example, the present invention can be further configured as follows: the graphene heating layer is block-type, the external membrane portion and the internal contact points of the massage drive circuit electrically connected to the interconnection line are both located between the graphene heating layers; more specifically, the internal contact points of the massage drive circuit electrically connected to the interconnection line are also located between the two side wirings, and the perforated contacts of the interconnection line electrically connected to the massage electrode are located outside the two side wirings.

[0017] By adopting the above-mentioned preferred technical features, the block-based graphene heating layer is used to provide an internal connection space, and the internal contacts of the external membrane part and the massage drive circuit to the interconnection line can be located in the blank area between the graphene heating layers, forming a spatial isolation protection of the external membrane part and the internal contacts relative to the edge of the patch. The middle space between the blocks of the graphene heating layer can be used as the second insulating base film to design a specific part of the external membrane part, so that the external membrane part can be connected from the back of the neck massage patch, which has better plug-in concealment without interfering with the heating. Specifically, the internal contacts of the massage drive line are also located between the two side wirings, and the perforated contacts that are electrically connected to the massage electrodes with the interconnection lines are located outside the two side wirings. A good spatial isolation is formed between the electrically connected internal contacts (line intensive area) and the corresponding perforated contacts (line evacuation area), so as to prevent the conductive material forming the massage electrode from overflowing through the perforated contacts and contaminating the massage drive circuit and the heating drive circuit.

[0018] The present invention can be further configured in a preferred structural example as follows: the neck massage patch further includes a jumper circuit layer formed on the second insulating base film and the graphene heating layer, the jumper circuit layer includes a temperature measurement circuit, the temperature measurement circuit forms an external connection point on the graphene heating layer and is electrically connected to the third terminal point of the external film portion, and the external connection point is used to directly connect the temperature sensing chip on the neck massage patch. Preferably, the arrangement order from the middle to the side of the plug-in side is the first terminal point, the third terminal point and the second terminal point.

[0019] By adopting the above-mentioned preferred technical features, the jumper circuit layer is used to provide an external connection point that can extend to the graphene heating layer to connect the temperature sensing chip or other control device on the back of the patch. The external connection point is electrically connected to the third terminal point of the external film part through the jumper circuit layer to achieve external information communication of the temperature measurement signal. Preferably, the first terminal point connected to the heating drive for the maximum current to pass through is located in the middle of the plug-in side, the second terminal point connected to the massage drive for the medium current to pass through is located at the outermost side of the plug-in side, and the third terminal point connected to the temperature measurement drive for the slight current to pass through is located between the first terminal point and the second terminal point, so as to reduce the electromagnetic interference of the large current of the heating drive circuit connected to the first terminal point to the massage drive circuit connected to the second terminal point, so as to improve the external power transmission quality of the patch product.

[0020] In a preferred structural example, the present invention can be further configured as follows: the jumper circuit layer further includes a nonlinear two-dimensional zigzag protection line arranged on both sides of the first terminal point, the second terminal point and the third terminal point. Preferably, the protection line crosses the massage drive circuit.

[0021] By adopting the above-mentioned preferred technical features, the jumper circuit layer also includes a nonlinear two-dimensional zigzag protection line to protect the circuit of the second insulating base film outside the external film portion, thereby preventing the peripheral circuit of the second insulating base film located around the external film portion from being pulled when the external film portion is lifted.

[0022] In a preferred structural example, the present invention can be further configured as follows: the first insulating base film and the second insulating base film are in an elliptical or approximately elliptical plane capsule shape; preferably, the massage electrodes are block-shaped, and the block gaps are formed in accordance with the extension direction of the human neck.

[0023] By adopting the above preferred technical features, the specific overlapping shape of the first insulating base film and the second insulating base film provides a short-side arc surface, which is convenient for attachment to the neck of the human body to both sides of the neck without protruding angles. In the preferred example, the block-type massage electrode is used and the block gap is formed in accordance with the extension direction of the human neck. When the neck massage patch is attached to the skin of the human neck and bends, the massage electrode is not easily peeled off or broken by the bending stress.

[0024] The second main purpose of the present invention is to provide a neck massager, comprising: a neck ring and a connecting seat located in the middle of the neck ring, the interface of the connecting seat is detachably provided with an electrode sheet, and the electrode sheet comprises a neck massage patch according to any of the technical solutions described above.

[0025] By adopting the above technical solution, the neck massage patch is used as the electrode sheet of the neck massager. When in use, it can be attached to the skin of the human neck and bend synchronously. It has the functions of neck massage and neck heating. The external film part formed in one piece with the second insulating base film is plug-connected to the neck massager, which can hide the external end of the neck massage patch and avoid unnecessary collision.

[0026] The third main purpose of the present invention is to propose a patch manufacturing method for manufacturing a neck massage patch according to any of the technical solutions described above, wherein the massage drive circuit and the heating drive circuit are formed in the same silver paste printing graphic layer.

[0027] By adopting the above technical solution, the massage drive circuit and the heating drive circuit are formed in the same silver paste printing graphic layer, the number of printing times is reduced and a neck massage patch with massage and heating functions and stable quality that can be mass-produced is produced.

[0028] The fourth main purpose of the present invention is achieved through the following technical solutions:

[0029] A patch manufacturing method is proposed, comprising the following steps:

[0030] Providing a first insulating base film, wherein a massage electrode is disposed on a contact surface of the first insulating base film, and an interconnection line electrically connected to the massage electrode is disposed on a pressing surface of the first insulating base film;

DETAILED DESCRIPTION

[0056] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments for understanding the inventive concept of the present invention, and cannot represent all the embodiments, nor are they interpreted as the only embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field on the premise of understanding the inventive concept of the present invention are within the scope of protection of the present invention.

[0057] It should be noted that if there are directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention, the directional indications are only used to explain the relative position relationship and movement of the components in a certain posture. If the specific posture changes, the directional indications will also change accordingly. In order to facilitate the understanding of the technical solution of the present invention, the neck massage patch of the present invention and the manufacturing method thereof are further described and explained in detail below, but they are not limited to the scope of protection of the present invention.

[0058] The drawings only illustrate the common features of multiple embodiments in the form of preferred examples, and the differences or distinctions are described in words or presented in comparison with the drawings. Therefore, based on the industry characteristics and technical essence, those skilled in the art should be able to correctly and reasonably understand and judge whether the individual technical features described below or any combination of them can represent the same embodiment, or whether multiple technical features that are mutually exclusive in technical essence can only represent different variant embodiments.

[0059] Figures 1 to 3 A three-dimensional schematic diagram of a neck massage patch disclosed in some embodiments of the present invention on the attachment surface, a three-dimensional schematic diagram on the contact surface, and a three-dimensional schematic diagram of the external film part of the attachment surface that can be tilted are respectively drawn. A neck massage patch includes: a first insulating base film 10, a second insulating base film 20 arranged on the first insulating base film 10, and a graphene heating layer 50 formed on the second insulating base film 20. The second insulating base film 20 is provided with a massage drive circuit 30 and a heating drive circuit 40 on the same surface away from the first insulating base film 10. Basically, the components can be stacked in sequence. In the example, in order to facilitate structural viewing and facilitate technical understanding, the insulating isolation layer that isolates the upper and lower isolation circuits from the surface is not drawn, and is supplemented in text.

[0060] The first insulating base film 10 is used as the first printing base layer. The first insulating base film 10 has a contact surface and a pressing surface corresponding to each other. The contact surface of the first insulating base film 10 is provided with a massage electrode 11 (refer to Figure 2 and Figure 6 ), the first insulating base film 10 is provided with interconnecting wires 12 electrically connected to the massage electrodes 11 (refer to Figure 7). The shape of the first insulating base film 10 is specifically an elliptical or nearly elliptical planar capsule. The first insulating base film 10 is specifically a PET insulating film, which can be transparent or colored, such as white, black or other colors. It is preferably transparent to facilitate the transmission of far-infrared light waves emitted by the graphene heating layer 50 to the contact surface. The function of the massage electrode 11 is to electrically contact the human neck to provide a biological massage current to stimulate the human neck; the function of the interconnection line 12 is to electrically connect the massage electrode 11 with the corresponding massage drive circuit 30 and be isolated between the film layer of the massage electrode 11 and the massage drive circuit 30. The electrical connection method between the interconnection line 12 and the massage electrode 11 is specifically a plurality of perforated contacts 13 (refer to Figure 7 ), the position of the perforated contact 13 is specifically close to the periphery of the first insulating base film 10 but not exposed to the peripheral side of the first insulating base film 10. Specifically, in a preferred example, the massage electrodes 11 are block-shaped, and block gaps 14 are formed between the massage electrodes 11 (refer to Figure 2 and Figure 6 ), formed in accordance with the extension direction of the human neck. When the neck massage patch is attached to the skin of the human neck and bends, the massage electrode is not easily peeled off or broken by the bending stress.

[0061] The second insulating base film 20 serves as a second printing base layer. The second insulating base film 20 is disposed on the pressed surface of the first insulating base film 10. The second insulating base film 20 is formed with a massage drive circuit 30 and a heating drive circuit 40 on a surface away from the first insulating base film 10. In addition, an external film portion 21 is integrally formed in the second insulating base film 20, and the boundary of the external film portion 21 can be defined by the slot 22 of the second insulating base film 20. The massage drive circuit 30 is electrically connected to the interconnection line 12 and can be connected to the corresponding massage electrode 11. The heating drive circuit 40 includes a heating electrode 41 and two side wirings 42 alternately connected to the heating electrode 41. In a specific example, the massage drive circuit 30 and the heating drive circuit 40 can be printed on the same surface of the second insulating base film 20. The massage drive circuit 30 is located between the wiring 42 on both sides of the heating drive circuit 40. The heating drive circuit 40 can constitute the appearance of the overall circuit layer located on the second insulating base film 20. Therefore, the cross-line portion of the massage drive circuit 30 is separated from the interconnection line 12 and densely arranged, and the massage drive signal is extended to the side of the other surface of the second insulating base film 20 through the interconnection line 12. The heating electrodes 41 of the heating drive circuit 40 are specifically arranged in a comb shape and are staggeredly connected to the wiring 42 on both sides. A specific example of the pattern of the heating drive circuit 40 and the massage drive circuit 30 can be found in Figure 8In one example, the heating drive circuit 40 and the massage drive circuit 30 are formed in the same circuit layer and overlap each other; specifically, the massage drive circuit 30 is included in the formation area of ​​the heating drive circuit 40 .

[0062] The massage drive circuit 30 and the heating drive circuit 40 are specifically formed by printing with conductive silver paste, which has better flexibility than copper wire or other pure metal conductive circuits; preferably, they are semi-transparent or diffractive to far-infrared light waves, which can be achieved by using the material ratio or width of the printed pattern. However, it is not limited that there is a gap between the strip heating electrodes 41 for the far-infrared light emitted by the graphene heating layer 50 to pass through, and the massage drive circuit 30 and the heating drive circuit 40 can also be made of conductive metal with total reflection. Since the massage electrode 11 and the driving circuit are separated and formed on different insulating base films, specifically silver paste printing, the massage electrode 11 that needs to be printed multiple times or printed with a larger thickness has the least interference effect on the dense line area of ​​the driving circuit. The massage drive circuit 30 includes a second terminal point 31 extending to the external membrane portion 21, and is connected to the internal contact point 32 electrically connected to the interconnection line 12. The heating drive circuit 40 includes a first terminal point 43 extending to the external membrane portion 21, which is electrically connected to the heating electrode 41 via the wiring 42. Generally, in order to allow a larger current to pass through, the width of the first terminal point 43 is greater than the width of the second terminal point 31 , so as to reduce abnormal heating of the first terminal point 43 .

[0063] The graphene heating layer 50 is formed on the second insulating base film 20 and covers the heating electrode 41 connected to the heating drive circuit 40. When powered on, the graphene heating layer 50 can generate heat and emit far-infrared light waves suitable for human health through the connection of the heating drive circuit 40. The graphene heating layer 50 is specifically distributed on both sides of the external membrane portion 21. The graphene heating layer 50 can be formed by printing or film pasting. It is preferred to print and form the graphene heating layer 50 so that the printed material of the graphene heating layer 50 can cover the front and both sides of the heating electrode 41. In different examples, the graphene heating layer 50 can also be formed by film pasting. The massage electrode 11 and the graphene heating layer 50 partially overlap based on different regional needs, but can be different graphics.

[0064] Therefore, the massage electrode 11 is formed on the contact surface of the first insulating base film 10 and is connected to the corresponding massage drive circuit 30 through the interconnection line 12. The massage electrode 11 is specifically distributed in blocks. The massage electrode 11 can be formed by printing or film pasting. It is preferably formed by printing with conductive silver paste, and the printing thickness of the massage electrode 11 can be greater than the printing thickness of the massage drive circuit 30 and the heating drive circuit 40. The printed pattern of the massage electrode 11 may also include a logo pattern (not shown) for product identification and to improve the texture. For example, when supplied to a specific customer, an S-shaped logo may be formed in the massage electrode 11. In addition to being formed by printing, the massage electrode 11 can also be formed by attachment or electroplating. Based on the consistency of the process equipment and easier attachment to the skin of the human neck, the massage electrode 11 is preferably formed by printing, which can appear softer.

[0065] See Figure 1 and Figure 3 The first terminal point 43 electrically connected to the heating drive circuit 40 and the second terminal point 31 electrically connected to the massage drive circuit 30 are aligned and arranged on the plug-in side of the external film portion 21, and the external film portion 21 can be tilted away from the first insulating base film 10 (see Figure 3 ).

[0066] The implementation principle of these basic embodiments is to use the first insulating base film 10 provided with the massage electrode 11 and the second insulating base film 20 for forming the graphene heating layer 50 to overlap each other to form a massage patch with a preheating function, and separate the massage driving circuit in the second insulating base film 20 that may interfere with the heating driving circuit 40 from the interconnection line 12 of the first insulating base film 10, so that the main circuit of the massage driving circuit 30 can be configured on the second insulating base film 20 on the same configuration surface as the heating driving circuit 40, and the formation of the graphene heating layer 50 does not interfere with the interconnection line 12 of the first insulating base film 10 and the massage electrode 11 under the isolation of the second insulating base film 20. In addition, the external film portion 21 is formed integrally in the second insulating base film 20, and does not interfere with the configuration of the interconnection line 12 of the first insulating base film 10 and the massage electrode 11. The external connection end of the massage electrode patch is confidential and easy to manufacture, and the heating driving circuit 40 and the massage electrode 11 are separated by at least the first insulating base film 10 and the second insulating base film 20.

[0067] In a preferred structural example, regarding the forming of the external film portion 21, the plug-in side of the external film portion 21 and the adjacent side adjacent to the plug-in side are surrounded by a continuously extending slot 22, and the shape of the slot 22 is a U-shape or a C-shape with three sides surrounded and one side placed. The pattern of the slot 22 can overlap on the first insulating base film 10. The second insulating base film 20 has a slot 22 with a pattern overlapping on the first insulating base film 10 to surround the external film portion 21. The external film portion 21 in the electrode patch is spaced from the edge of the first insulating base film 10. When not warped, the external film portion 21 can be hidden in the second insulating base film 20 and does not extend to the edge of the electrode patch, and has good moisture resistance. The forming method of the external film portion 21 includes preforming or insulating etching.

[0068] In a preferred structural example, regarding the pattern of the graphene heating layer 50, the graphene heating layer 50 is block-type, and the external membrane portion 21 and the internal contact point 32 of the massage drive circuit 30 electrically connected to the interconnection line 12 are both located between the graphene heating layer 50; more specifically, the internal contact point 32 of the massage drive circuit 30 electrically connected to the interconnection line 12 is also located between the two side wirings 42, and the perforated contact 13 of the interconnection line 12 electrically connected to the massage electrode 11 is located outside the two side wirings 42. The block-type graphene heating layer 50 is used to provide an internal connection space, and the external film portion 21 and the internal contact point 32 of the massage drive circuit 30 to the interconnection line 12 can be located in the blank area between the graphene heating layer 50, forming a spatial isolation protection of the external film portion 21 and the internal contact point 32 relative to the edge of the patch. The middle space between the blocks of the graphene heating layer 50 can be used as the second insulating base film 20 to design a specific part of the external film portion 21, so that the external film portion 21 can be connected from the back of the neck massage patch, which has better non-interference with the heating side of the plug-in concealment. Specifically, the inner contact 32 of the massage drive line is also located between the two side wirings 42, and the perforated contact 13 electrically connected to the massage electrode 11 with the interconnection line 12 is located outside the two side wirings 42, so that a good spatial isolation is formed between the electrically connected inner contact 32 (line dense area) and the corresponding perforated contact 13 (line evacuation area), so as to prevent the conductive material forming the massage electrode 11 from overflowing through the perforated contact 13 and contaminating the massage drive line 30 and the heating drive line. A specific example pattern of the interconnection line 12 can be found in Figure 7 A specific example pattern of the graphene heating layer 50 can be found in Fig. 9 .

[0069] In a preferred structural example, regarding the heating sensing function of the neck massage patch, the neck massage patch further includes a jumper circuit layer 60, which is formed on the second insulating base film 20 and the graphene heating layer 50, and the jumper circuit layer 60 includes a temperature measurement circuit 61, and the temperature measurement circuit 61 forms an external connection point 62 on the graphene heating layer 50, and is electrically connected to the third terminal point 63 of the external film part 21, and the external connection point 62 is used to directly connect the temperature sensing chip on the neck massage patch. Preferably, the arrangement order from the middle to the side based on the plug-in side is the first terminal point 43, the third terminal point 63 and the second terminal point 31. The jumper circuit layer 60 is used to provide an external connection point 62 that can extend to the graphene heating layer 50 to connect the temperature sensing chip or other control devices on the back of the patch. The external connection point 62 is electrically connected to the third terminal point 63 of the external film part 21 through the jumper circuit layer 60, so as to achieve external information communication of the temperature measurement signal. Preferably, the first terminal point 43 connected to the heating drive for the maximum current to pass through is located in the middle of the plug-in side, the second terminal point 31 connected to the massage drive for the medium current to pass through is located at the outermost side of the plug-in side, and the third terminal point 63 connected to the temperature measurement drive for the light current to pass through is isolated between the first terminal point 43 and the second terminal point 31, so as to reduce the electromagnetic interference of the large current of the heating drive circuit 40 connected to the first terminal point 43 on the massage drive circuit 30 connected to the second terminal point 31, so as to improve the external power transmission quality of the patch product. Specifically, the width of the first terminal point 43 is also greater than the width of the third terminal point 63, and the third terminal point 63 has an extension section, and the connection with the temperature measurement circuit 61 is a cross-layer stacking connection (see Figure 1 , Figure 3 ), that is, the base layer or the entirety of the third terminal point 63 and the jumper circuit layer 60 are printed on different layers. A specific example pattern of the jumper circuit layer 60 can be found in Fig.10 A specific example pattern of the external film portion 21 can be found in Fig.11 .

[0070] In application, the temperature sensing chip can be set on the back of the neck massage patch and connected to the external contact point 62 on the graphene heating layer 50 to sense the temperature of the graphene heating layer 50 in real time to avoid overheating of the human neck or temperature sensing for preheating before wearing.

[0071] More specifically, the base layers of the first terminal point 43, the second terminal point 31 and the third terminal point 63 are formed together during the printing process of the massage drive circuit 30 and the heating drive circuit 40, and then appropriate reinforcing plates or structural reinforcement measures are used to improve the plug-in ability of the external membrane part 21.

[0072] In a preferred structural example, regarding the circuit reinforcement design of the second insulating base film 20, the jumper circuit layer 60 also includes a nonlinear two-dimensional zigzag protection line 64, which is arranged on both sides of the first terminal point 43, the second terminal point 31 and the third terminal point 63. Preferably, the protection line 64 crosses the massage drive circuit 30. The jumper circuit layer 60 also includes a nonlinear two-dimensional zigzag form, such as a U-shaped protection line 64 with an opening toward the terminal point, which is used to protect the circuit of the second insulating base film 20 outside the external film part 21 to prevent the external film part 21 from pulling the peripheral circuit of the second insulating base film 20 located around the external film part 21 when the external film part 21 is tilted, mainly to protect the positioning of the internal contact 32. An insulating layer (not shown) may be provided between the protection line 64 and the heating drive circuit 40. In a preferred structural example, regarding the optional shape design of the first insulating base film 10 and the second insulating base film 20, the first insulating base film 10 and the second insulating base film 20 are elliptical or approximately elliptical plane capsule shapes. The specific overlapping shape of the first insulating base film 10 and the second insulating base film 20 provides an arc surface of the short side, which is convenient for attaching to the neck of a human body to both sides of the neck without any protruding corners during use.

[0073] Regarding the application of the neck massage patch, the present invention also proposes a neck massager in other examples, including: a neck collar and a connecting seat located in the middle of the neck collar, the interface of the connecting seat is detachably provided with an electrode sheet, and the electrode sheet includes a neck massage patch as described above. The neck massage patch is used as an electrode sheet of a neck massager, and when used, it can be attached to the human neck skin and bend synchronously, and has the functions of neck massage and neck heating, and is plug-connected to the neck massager by an external film portion 21 integrally formed by a second insulating base film 20, which can hide the external end of the neck massage patch and avoid unnecessary collisions.

[0074] Regarding the production of the neck massage patch, the present invention also proposes a patch manufacturing method in other examples, which is used to manufacture a neck massage patch of any of the above examples, wherein the massage drive circuit 30 and the heating drive circuit 40 are formed in the same silver paste printing pattern layer, specifically between the second insulating base film 20 and the insulating back film (not shown) for covering the graphene heating layer 50. In this way, the number of printing times can be reduced and a neck massage patch with massage and heating functions and stable quality that can be mass-produced can be produced.

[0075] See also Figure 4 In another example, the present invention also provides a patch manufacturing method, including the following steps in conjunction with reference to Figures 5 to 11 Steps:

[0076] Step S1: See Figure 5A first insulating base film 10 is provided, wherein a massage electrode 11 is provided on the contact surface of the first insulating base film 10 (see Figure 6 ), the first insulating base film 10 is provided with interconnecting wires 12 electrically connected to the massage electrodes 11 (see Figure 7 ); In this step, usually a plurality of unformed first insulating base films 10 are formed in a thin film mother sheet to facilitate mass production and large-area printing at one time. In order to facilitate understanding, the shape of the first insulating base film 10 after forming is pre-drawn; the formation order of the massage electrode 11 can be performed before or after the formation order of the interconnection line 12; before forming the massage electrode 11, the first insulating base film 10 can be pre-formed with perforations corresponding to the perforated contacts 13; usually the silver paste printing thickness of the massage electrode 11 is greater than the silver paste printing thickness of the interconnection line 12. After double-sided printing, the silver paste naturally flows into the perforations to form the perforated contacts 13; preferably The sequence of steps is selected but not limited to, first printing the thicker massage electrode 11 and then turning over to print the thinner interconnection line 12. This is because the thicker silver paste has a higher printing consistency and is less likely to pass through the overflowed non-printing surface of the film. After the film is turned over, the thinner interconnection line 12 is printed. A silver paste with a lower consistency can be used for printing. The lower the consistency of the silver paste, the stronger the hole filling and penetration ability. The perforated contact 13 with double-sided conduction can be naturally formed, and the overflow diffusion can be controlled by the process. In addition, when the silver paste of the interconnection line 12 is baked, it is equivalent to that the massage electrode 11 is also baked twice, which can shorten the first silver paste baking time of the massage electrode 11 before turning over.

[0077] Step S2: See Figure 8 The second insulating base film 20 is disposed on the pressed surface of the first insulating base film 10, and the surface of the second insulating base film 20 is formed with a massage drive circuit 30 and a heating drive circuit 40, specifically a same-layer silver paste printing structure; and the second insulating base film 20 is integrally defined with an external film portion 21 (see Fig.11 ), at the internal contact point 32, the massage drive circuit 30 is electrically connected to the interconnection line 12, and the heating drive circuit 40 includes a heating electrode 41 and two side wirings 42 alternately connected to the heating electrode 41; the integral definition of the external membrane portion in this step includes a situation where an area of ​​the external membrane portion is reserved but not formed or another situation where the external membrane portion 21 has been formed; in this step, the base layer of the first terminal point 43, the second terminal point 31 and the third terminal point 63 has been formed in the external membrane portion or a predetermined area of ​​the external membrane portion;

[0078] Step S3: See Fig. 9, forming a graphene heating layer 50 on the second insulating base film 20, the graphene heating layer 50 covers the heating electrode 41 connected to the heating driving circuit 40; in a specific example, the graphene heating layer 50 is block-shaped, and the block gap is used to avoid the massage driving circuit 30 and the external film part (or a predetermined area of ​​the external film part);

[0079] Among them, the first terminal point 43 electrically connected to the heating drive circuit 40 and the second terminal point 31 electrically connected to the massage drive circuit 30 are aligned and arranged on the plug-in side of the external film part 21, and the external film part 21 can be tilted away from the first insulating base film 10.

[0080] By adopting the above technical solution, a neck massage patch suitable for a neck massager can be manufactured, so that the joint with the neck massager can be located on the back of the patch, which is convenient for replacement and updating.

[0081] In a preferred method example, the plug-in side of the external film portion 21 and the adjacent side adjacent to the plug-in side are surrounded by a continuously extending slot 22 , and the pattern of the slot 22 overlaps the first insulating base film 10 .

The temperature measurement circuit 61 can cross the heating drive circuit 40 to form circuit external protection.
