Description

Technical Field

[0001] The invention relates to the technical field of human neck massage, in particular to a neck massage patch and a manufacturing method thereof. 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 its temperature detection method, which are disclosed in 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 play the functions of neck massage contact and uniform heating, and meet the requirements of consumable materials that can be standardized and mass-produced with stable quality. Summary of the invention

[0005] The main purpose of the present invention is to provide a neck massage patch, the main improvement of which is to solve the above-mentioned problems and to simultaneously play the functions of neck massage contact and uniform heating.

[0006] The second main purpose of the present invention is to provide a method for manufacturing a neck massage patch 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] An insulating base film, as a printing base layer, the insulating base film having a symmetrically foldable contact film portion, a heating film portion, and an interconnecting film portion integrally connecting the contact film portion and the heating film portion;

[0010] The massage drive circuit and the heating drive circuit are printed on the same surface of the insulating base film, the massage drive circuit is located in the contact film portion, and the heating drive circuit is located in the heating film portion; the massage drive circuit includes an interconnection line extending to one side of the heating film portion through the interconnection film portion;

[0011] A graphene heating layer, formed on the heating film portion and covering the heating electrode connected to the heating drive circuit;

[0012] A massage electrode formed on the contact membrane portion and connected to the massage drive circuit;

[0013] When the contact film portion and the heating film portion are folded and attached to each other, the interconnection film portion is bent, and the gap between the graphene heating layer and the massage electrode is maintained including the sum of the thickness of the contact film portion and the heating film portion.

[0014] By adopting the above technical solution, the contact film part and the heating film part are folded and attached to each other. After the interconnection film part is bent, the interconnection line is located on the outer side of the bend of the interconnection film part and is not easily broken by bending. The same-side printing and folding method avoids the design of perforated vias. Since the gap between the graphene heating layer and the massage electrode is maintained to include the thickness of the contact film part and the heating film part, the temperature rise path from the graphene heating layer to the massage electrode includes the thickness of the two layers of the insulating base film after folding, and the uniformity of the heat conduction path makes the massage electrode temperature rise uniform, and there will be no problem of local abnormal heating. In addition, the neck massage patch does not require double-sided printed circuits or perforation of the insulating base film. The viscosity adjustment change of the printed coating based on the need for thick or thin coating will not cause the problem of leakage and diffusion. The elasticity of the manufacturing process window becomes larger, and the quality of the patch product can be maintained stable under mass production. Therefore, the neck massage patch can be used as an electrode sheet of a neck massager, becoming a consumable material that can be mass-produced with stable quality and can exert the effect of uniform neck massage contact and heating.

[0015] In a preferred structural example, the present invention can be further configured as follows: an external membrane portion is integrally formed by the heating membrane portion, a first terminal point electrically connected to the massage drive circuit and a second terminal point electrically connected to the heating drive circuit are aligned and arranged on the plug-in side of the external membrane portion, and the plug-in side of the external membrane portion and the adjacent side edges of the adjacent plug-in side are formed by surrounding continuous slots, so that the plug-in side can be tilted in the direction away from the heating membrane portion.

[0016] By adopting the above-mentioned preferred technical features, the external membrane portion formed integrally by the heating membrane portion can be used to align the first terminal point of the massage drive and the second terminal point of the heating drive on the plug-in side of the external membrane portion. The external membrane portion is provided with a continuous slot, and the plug-in side can be tilted away from the heating membrane portion for plugging into the interface inside the connection socket of the neck massager. When the neck massage patch is in contact with the skin of the human neck during use, the pressing force will not act on the external connection between the first terminal point and the second terminal point. Therefore, there is a good electrical connection between the massage / heating drive circuit of the neck massage patch and the control circuit of the neck massager that can resist neck pressure.

[0017] In a preferred structural example, the present invention can be further configured as follows: the heating drive circuit also includes wiring on both sides, alternately connecting the heating electrodes; the graphene heating layer is block-based, and the external film portion is located at a specific position of the heating film portion between the graphene heating layers.

[0018] By adopting the above-mentioned preferred technical features, the heating electrodes are alternately connected by the wiring on both sides of the heating drive circuit, so that the heating electrodes are comb-shaped connection structures, and the connection points of the wiring on both sides of the heating electrodes are arranged in a Z-shape. The same block of the graphene heating layer can be isolated by the position of the heating electrodes and can be divided into multiple heating areas. In addition, the middle space between the blocks of the graphene heating layer can be used as the heating film part to design a specific part of the external film part, so that the external film part can be connected from the back of the neck massage patch, which has better non-interference heating side concealment.

[0019] The present invention can be further configured as follows in a preferred structural example: the neck massage patch further includes a jumper circuit layer, which is formed on the heating film portion, the heating drive circuit and the graphene heating layer, and the jumper circuit layer includes a jumper wire, which connects the interconnection line and the first terminal point of the massage drive circuit, and crosses the heating drive circuit and the graphene heating layer; preferably, the jumper circuit layer also includes a protective wire, which is annularly surrounding the first terminal point and the second terminal point; preferably, the jumper circuit layer also includes a bridging bottom layer located at the contact film portion, and two or more of the massage electrodes are combined on the bridging bottom layer.

[0020] By adopting the above-mentioned preferred technical features, the jumper circuit layer is used to electrically connect the interconnection line of the massage drive circuit and the corresponding first terminal point, and the printing on both sides of the insulating base film is replaced by multiple printing on the same surface. The graphene heating layer isolates the jumper circuit layer and the heating electrode of the heating drive circuit, and a temperature sensing chip or other control device can be configured on the graphene heating layer; in addition, there is no other wire printing or lamination on the mutually fitting surface of the heating film part and the contact film part (i.e., the bottom surface of the insulating base film), and there is a uniform and consistent insulation isolation thickness after folding. In a preferred example, the protective wire of the jumper circuit layer is used to surround the first terminal point and the second terminal point in a ring shape, and the heating film part has a thicker shape around the opening area after the external film part is lifted, and the structure around the opening area is enhanced to reduce the shape deformation of the heating film part around the opening area after the external film part is lifted and pulled out.

[0021] In a preferred structural example, the present invention can be further configured as follows: the jumper circuit layer also includes a temperature measurement circuit, forming a contact on the graphene heating layer and electrically connected to the third terminal point of the heating film portion, and the contact 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 second terminal point, the first terminal point and the third terminal point.

[0022] By adopting the above-mentioned preferred technical features, the second 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 first terminal point connected to the massage drive for the moderate current to pass through is located at the outer side of the plug-in side, and the third terminal point connected to the temperature measurement drive for the light current to pass through is located at the outermost side of the plug-in side, so as to reduce the electromagnetic induction effect caused by the current on the external membrane part, thereby improving the product's electrical transmission quality.

[0023] The present invention can be further configured in a preferred structural example as follows: the contact membrane portion and the heating membrane portion are elliptical or approximately elliptical plane capsule-shaped, and the interconnecting membrane portion is aligned with the short axis centerline of the contact membrane portion and the heating membrane portion;

[0024] Preferably, the contact film portion is provided with a first folding alignment point, and the heating film portion is provided with a second folding alignment point.

[0025] By adopting the above preferred technical features, the contact membrane portion and the heating membrane portion provide a short-side arc surface, which is convenient for attaching to the human neck during use, and the interconnection membrane portion is aligned with the short axis center line of the contact membrane portion and the heating membrane portion, which will make the folding length shorter, so as to facilitate folding and folding alignment. In the preferred example, the first folding alignment point of the contact membrane portion and the second folding alignment point of the heating membrane portion can be aligned with each other, so that the contact membrane portion and the heating membrane portion are aligned when folded and attached.

[0026] In a preferred structural example, the present invention can be further configured as follows: the massage electrodes are segmented, and the segment gaps are formed in accordance with the extension direction of the human neck.

[0027] By adopting the above-mentioned preferred technical features, the massage electrodes are segmented and the gaps between the segments are formed in 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 electrodes are not easily peeled off or broken due to bending stress.

[0028] 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.

[0029] 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 thickness of the contact membrane part and the heating membrane part after folding and the interval between the heating area (graphene heating layer) and the massage electrode are stably maintained. The heat conduction path is uniform and effectively electrically isolated. It can be disassembled and replaced after the use cycle is exceeded, which meets the requirements of standardized mass production and consumable materials with stable quality.

[0030] The third main purpose of the present invention is to propose a method for manufacturing a neck massage patch, which is used to manufacture 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 a first silver paste printing graphic layer.

[0031] By adopting the above technical solution, the massage drive circuit and the heating drive circuit are formed in the first 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.

[0032] The fourth main purpose of the present invention is achieved through the following technical solutions:

DETAILED DESCRIPTION

[0065] 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.

[0066] It should be noted that if there are directional indications (such as up, down, left, right, front, back, etc.) involved 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 and the manufacturing method of the present invention are further described and explained in detail below, but they are not limited to the scope of protection of the present invention.

[0067] The drawings only illustrate the common parts of multiple embodiments in the form of preferred examples, and the parts with differences or distinctions are described in text or presented in comparison with the drawings. Therefore, based on the industrial characteristics and technical essence, technicians familiar with the field should 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 with mutually exclusive technical essences can only represent different variant embodiments.

[0068] Figures 1 to 4 A neck massage patch disclosed in some embodiments of the present invention is respectively illustrated in a plane before being folded, a three-dimensional shape at a first angle, a three-dimensional shape at a second angle, and a three-dimensional shape after being folded. A neck massage patch comprises: an insulating base film 10, a massage drive circuit 20 and a heating drive circuit 30 arranged on the insulating base film 10, a graphene heating layer 40 partially covering the heating drive circuit 30, and a massage electrode 50 partially covering the massage drive circuit 20. The components basically constituted can be stacked in sequence, and the insulating base film 10 usually defines a short axis center line and a long axis center line after being folded. Figures 5 to 7 The cross section of the long axis centerline of the neck massage patch of the present invention before being folded, the cross section of the short axis centerline before being folded, and the cross section along the short axis centerline after being folded are further illustrated. In the example, in order to facilitate the structure viewing and facilitate technical understanding, the insulating isolation layer and the adhesive layer as the intermediate layer are not drawn, and are supplemented by text.

[0069] The insulating base film 10 is used as a printing base layer, and the insulating base film 10 has a symmetrically foldable contact film portion 11, a heating film portion 12, and an interconnection film portion integrally connecting the contact film portion 11 and the heating film portion 12. The interconnection film portion is a curved portion where the contact film portion 11 and the heating film portion 12 are integrally interconnected after the contact film portion 11 and the heating film portion 12 are folded in half; the shape of the insulating base film 10 is specifically a combination of two ellipses or nearly ellipses that are integrally interconnected on the long sides, and the insulating base film 10 can be defined with a short axis centerline A (see Fig. 9 ), passes through the center points of the contact film portion 11 and the heating film portion 12, which also means that the center points of the contact film portion 11 and the heating film portion 12 are aligned on the short axis center line A, and two long axis center lines can be spread out before folding. In different examples, the long axis center line can also be selected as the reference center line for folding the patch in half, and two short axis center lines can be spread out before folding. The 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 to the contact film portion 11. Usually, an external film portion 14 is also divided in the middle part of the heating film portion 12.

[0070] The massage drive circuit 20 and the heating drive circuit 30 are printed and formed on the same surface of the insulating base film 10. The massage drive circuit 20 is located in the contact film portion 11, and the heating drive circuit 30 is located in the heating film portion 12; the massage drive circuit 20 includes an interconnection line 21, which extends to one side of the heating film portion 12 through the interconnection film portion. The function of the interconnection line 21 is equivalent to the perforated conductive structure, which serves as the electrical interconnection of the circuit layers in the upper and lower spatial positions after folding. The interconnection line 21 bent after folding connects the electrodes or signals located in different layers, and the perforation of the insulating base film 10 can be omitted. The heating drive circuit 30 specifically includes two-side wiring 33 and a comb-shaped heating electrode 31 with staggered connection wiring 33. The massage drive circuit 20 and the heating drive circuit 30 are specifically formed by printing conductive silver paste, which has better flexibility than copper wire or other pure metal conductive circuits; preferably, it has semi-transmittance or diffraction 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 to this. There are gaps between the strip heating electrodes 31 for the far infrared light emitted by the graphene heating layer 40 to pass through. The massage driving circuit 20 and the heating driving circuit 30 can also be made of a fully reflective conductive metal.

[0071] The graphene heating layer 40 is formed on the heating film portion 12 and covers the heating electrode 31 connected to the heating driving circuit 30 (refer to Fig.11 ). When powered on, the graphene heating layer 40 can generate heat and emit far-infrared light waves suitable for human health through the connection of the heating drive circuit 30. The graphene heating layer 40 is specifically distributed on both sides of the external film portion 14. The graphene heating layer 40 can be formed by printing or film pasting. It is preferred to print and form the graphene heating layer 40 so that the printed material of the graphene heating layer 40 can cover the front and both sides of the heating electrode 31. In different examples, the graphene heating layer 40 can also be formed by film pasting.

[0072] The massage electrode 50 is formed on the contact film portion 11 and connected to the massage drive circuit 20. The massage electrode 50 is specifically distributed in blocks. The massage electrode 50 can be formed by printing or film pasting. It is preferably formed by printing with conductive silver paste. The printing thickness of the massage electrode 50 can be greater than the printing thickness of the massage drive circuit 20 and the heating drive circuit 30. When the bottom layer of the massage electrode 50 is also provided with a bridging bottom layer 63 (see Fig.12 and Fig.13), the printed pattern of the massage electrode 50 may also include a logo pattern (not shown) for product identification and to improve the quality. For example, when supplied to a specific customer, an S-shaped logo may be formed in the massage electrode 50. In addition to being formed by printing, the massage electrode 50 may also be formed by attachment or electroplating. Based on the consistency of the process equipment and easier attachment to the human neck skin, the massage electrode 50 is preferably formed by printing, which can appear softer.

[0073] When the contact film portion 11 and the heating film portion 12 are folded and attached to each other, the interconnection film portion is tortuous, and the interconnection line 21 is naturally tortuous, and the gap between the graphene heating layer 40 and the massage electrode 50 is maintained to include the sum of the thickness of the contact film portion 11 and the heating film portion 12, that is, the gap between the graphene heating layer 40 and the massage electrode 50 is maintained at more than twice the thickness of the insulating base film 10 itself (taking into account the thickness of the adhesive layer between the contact film portion 11 and the heating film portion 12). The massage electrode 50 and the graphene heating layer 40 are partially overlapped based on different regional needs, but can be different patterns.

[0074] The implementation principle of these basic embodiments is to fold the contact film portion 11 and the heating film portion 12 to fit each other, and after the interconnection film portion is bent, the interconnection line 21 is located on the outer side of the bend of the interconnection film portion and is not easily broken by bending. The same-side printing and folding method avoids the design of perforated holes, and since the gap between the graphene heating layer 40 and the massage electrode 50 is maintained to include the thickness of the contact film portion 11 and the heating film portion 12, the temperature rise path from the graphene heating layer 40 to the massage electrode 50 includes the thickness of the two layers of the insulating base film 10 after folding, and the uniformity of the heat conduction path makes the massage electrode 50 temperature rise uniform, and there will be no problem of local abnormal heating. In addition, the neck massage patch does not require double-sided printed circuits or perforation of the insulating base film 10. The viscosity adjustment of the printed coating based on the need for thick or thin coating will not cause leakage and diffusion problems. The flexibility of the process window in manufacturing becomes larger, and the quality of the patch product can be maintained stable in mass production. Therefore, the neck massage patch can be used as an electrode sheet of a neck massager, becoming a consumable material that can be mass-produced with stable quality and can exert the effects of uniform contact and heating of neck massage.

[0075] In a preferred structural example, the heating film portion 12 is integrally formed with the external film portion 14, and the first terminal point 22 electrically connected to the massage drive circuit 20 and the second terminal point 32 electrically connected to the heating drive circuit 30 are aligned and arranged on the plug-in side of the external film portion 14; and the plug-in side of the external film portion 14 and the adjacent side edge adjacent to the plug-in side are surrounded by a continuous slot 15, so that the plug-in side can be tilted away from the heating film portion 12 (see FIG. 1 ). Fig.14), realize the signal extraction on the back side of the neck massage patch (away from the contact surface of the human neck). The continuous slot 15 is generally U-shaped (such as Figure 1 As shown). Using the above preferred description, the external membrane portion 14 formed integrally by the heating membrane portion 12 aligns the first terminal point 22 of the massage drive and the second terminal point 32 of the heating drive on the plug-in side of the external membrane portion 14. The external membrane portion 14 is provided with a continuous slot 15, and the plug-in side can be tilted away from the heating membrane portion 12 for plugging into the interface inside the connection socket of the neck massager. When the neck massage patch is in contact with the skin of the human neck during use, the pressing force will not act on the external connection between the first terminal point 22 and the second terminal point 32. Therefore, there is a good electrical connection between the massage / heating drive circuit of the neck massage patch and the control circuit of the neck massager that can resist neck pressure.

[0076] More specifically, the external film portion 14 is also provided with a third terminal point 71 for transmitting the temperature sensing signal.

Using the above preferred description, the second terminal point 32 connected to the heating drive for the maximum current to pass through is located in the middle of the plug-in side, and can have a wider line width; the first terminal point 22 connected to the massage drive for the medium current to pass through is located on the outer side of the plug-in side; the third terminal point 71 connected to the temperature measurement drive for the mild current to pass through is located on the outermost side of the plug-in side, so as to reduce the electromagnetic induction effect caused by the current on the external membrane part 14, so as to improve the electrical transmission quality of the patch product. However, in different non-limiting examples, the width and arrangement order of the second terminal point 32, the first terminal point 22 and the third terminal point 71 on the external membrane part 14 can be adjusted arbitrarily and appropriately.

In addition, the intermediate space between the blocks of the graphene heating layer 40 can be used as the heating film portion 12 for designing a specific position of the external film portion 14, so that the external film portion 14 can be connected from the back of the neck massage patch, which has better plug-in side concealment without interfering with heating.

[0079] In a preferred structural example, the neck massage patch further includes a jumper circuit layer formed on the heating film portion 12, the heating drive circuit 30 and the graphene heating layer 40, and the jumper circuit layer specifically includes a jumper wire 61, which connects the interconnection line 21 and the first terminal point 22 of the massage drive circuit 20, and crosses the heating drive circuit 30 and the graphene heating layer 40; using the above preferred description, the jumper circuit layer is used to electrically connect the interconnection line 21 of the massage drive circuit 20 and the corresponding first terminal point 22, and multiple printings on the same surface replace the printing on both sides of the insulating base film 10, and the graphene heating layer 40 isolates the jumper circuit layer from the heating electrode 31 of the heating drive circuit 30, and a temperature sensing chip or other control device can be configured on the graphene heating layer 40; in addition, the mutually fitting surface of the heating film portion 12 and the contact film portion 11 (i.e., the bottom surface of the insulating base film 10) has no other wire printing or lamination, and has a uniform insulation isolation thickness after folding.

In a preferred example, the protection line 62 of the jumper circuit layer is used to annularly surround the first terminal point 22 and the second terminal point 32, and the heating film portion 12 has a thicker shape around the opening area after the external film portion 14 is lifted, and the structure around the opening area is enhanced to reduce the shape deformation of the heating film portion 12 around the opening area after the external film portion 14 is lifted and pulled out.

[0081] In a preferred structural example, the contact membrane portion 11 and the heating membrane portion 12 are elliptical or approximately elliptical plane capsules, and the interconnected membrane portion is aligned with the short axis center line A of the contact membrane portion 11 and the heating membrane portion 12.

The notch where the first folding alignment point 16 and the second folding alignment point 17 are aligned with each other after folding can also be used as a positioning point for the neck massage patch to be installed on the neck massager.
