The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0038] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists, A and B exist at the same time, and B exists.

[0041] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0042] The heating electrode patch usually includes two functional layers. One layer is provided with a heating circuit for heating to achieve better physical therapy effects. The other layer is provided with a conductive area for transmitting the pulse signal of the physical therapy device to the human skin to achieve physical therapy functions. Based on this, the heating electrode patch itself has a certain degree of thickness.

[0043] When realizing automatic temperature control, the existing heating electrode patch selects to connect the PTC (Positive Temperature Coefficient) heating element to the heating circuit, so as to quickly heat up when the temperature is low to increase the temperature, and slowly heat up when the temperature is high to reduce power loss.

[0044] The PTC heating element is composed of a PTC ceramic heating element and an aluminum tube. When the PTC heating element is applied to a patch that needs to fit the human skin, the thickness of the heating electrode patch is increased on the basis of the thickness of the heating electrode patch itself, making the heating electrode patch thicker as a whole and difficult to fit the human skin.

[0045] Based on this, the inventor of the present application found that a thinner electronic device capable of automatic temperature control can be selected to connect to the heating circuit of the heating electrode patch, and based on the electronic device, the overall structure of the heating electrode patch can be improved to reduce the overall thickness of the heating electrode patch. For example, by connecting a PTC thermistor, which is usually less than a few millimeters thick, to the heating circuit of the heating electrode patch, the characteristic of the PTC thermistor that the resistance value increases with the temperature of the resistor body can be used to achieve automatic temperature control of the heating electrode patch, and the thickness of the heating electrode patch can be avoided from increasing significantly.

[0046] The overall structure of the heating electrode patch is improved based on the PTC thermistor. Specifically, the first and second wirings of the heating circuit can be etched on one side of a polyimide film (PI film), and a conductive area can be etched on the other side of the PI film to obtain a heating circuit with automatic temperature control by connecting the PTC thermistor, the first wiring formed by etching, and the second wiring, so that the structure of the heating electrode patch that realizes the automatic temperature control function and the heating function is thinner; the conductive area is etched on the other side of the PI film to transmit electrical signals to human skin through the conductive area to realize the physical therapy function, so that the structure of the heating electrode patch that realizes the physical therapy function is thinner; the heating circuit with automatic temperature control is obtained on one side of the PI film, and the conductive area is etched on the other side of the PI film, so that the automatic temperature control function, the heating function and the physical therapy function can be realized on one PI film, thereby reducing the overall thickness of the heating electrode patch.

[0047] The heating electrode patch provided in the embodiment of the present application includes but is not limited to use in the field of physical therapy, and can also be widely used in other fields, for example, in the field of beauty care to help tighten the skin, improve skin quality, etc.

[0048] Specifically, see Figure 1 , Figure 1 The structure diagram of the heating electrode patch provided in the embodiment of the present application is shown, wherein: Figure 1 P1 shows a schematic diagram of the first side of the PI film, Figure 1 P2 in FIG. 1 shows a schematic diagram of the second side of the PI film. Figure 1As shown, the heating electrode patch 10 includes a PI film 110, a temperature control component 120, a first electrode 130, a second electrode 140 and a third electrode 150; the temperature control component 120 includes at least one PTC thermistor; the first electrode 130 is used to connect the positive electrode of the power supply, the second electrode 140 is used to connect the negative electrode of the power supply, and the third electrode 150 is used to connect the electrical signal interface; the temperature control component 120 is fixed to the first surface 11a of the PI film; the first surface 11a of the PI film is etched to form a first wiring 111 and a second wiring 112, one end of the first wiring 111 is connected to the temperature control component 120, the other end of the first wiring 111 is connected to the first electrode 130, one end of the second wiring 112 is connected to the temperature control component 120, and the other end of the second wiring 112 is connected to the second electrode 140, so that a passage is formed between the first electrode 130, the temperature control component 120 and the second electrode 140; the second surface 11b of the PI film is etched to form a conductive area 113, and the conductive area 113 is connected to the third electrode 150.

[0049] Among them, the PI film 110 is a thermosetting plastic, which is usually prepared from polyimide resin by thin film technology and has the characteristics of high temperature resistance, chemical corrosion resistance, and good insulation.

[0050] See also Figure 2 , Figure 2 A circuit structure diagram of a temperature control component provided in an embodiment of the present application is shown. Figure 2 P1 shows a circuit structure diagram when the temperature control component 120 includes a PTC thermistor 121. Figure 2 FIG. 1 shows a circuit structure diagram when the temperature control component 120 includes a plurality of PTC thermistors 122 to 124. Figure 2 As shown in P1, when the temperature control component 120 is a PTC thermistor, the PTC thermistor 121 is fixed to the first surface of the PI film and connected to the first wiring and the second wiring of the PI film; Figure 2 As shown in P2, when the temperature control component 120 is a plurality of parallel PTC thermistors, it is necessary to connect the plurality of PTC thermistors 121 to 124 in parallel, and then connect the temperature control component 120 formed by the plurality of parallel PTC thermistors to the first wiring and the second wiring of the PI film.

[0051] Among them, the PTC thermistor is a temperature sensor made by utilizing the positive temperature coefficient effect of semiconductor materials. Its resistance value is relatively low below a certain temperature, and it will increase sharply after exceeding this temperature. This characteristic enables the PTC thermistor to be used in applications such as overcurrent protection, circuit stability control, temperature measurement and control. Therefore, by connecting the PTC thermistor to the heating circuit of the heating electrode patch 10, automatic temperature control of the heating electrode patch 10 can be achieved; furthermore, the volume of the PTC thermistor can be as small as a few millimeters, and its thickness can be as thin as a few microns to tens of microns. Therefore, by connecting the PTC thermistor to the heating circuit of the heating electrode patch 10, the thickness of the heating electrode patch 10 will not cause a significant increase in the thickness of the heating electrode patch 10.

[0052] The method of fixing the temperature control component 120 on the PI film 110 can be selected according to actual needs. For example, the temperature control component 120 can be welded to the first surface 11a of the PI film, or the temperature control component 120 can be bonded to the first surface 11a of the PI film.

[0053] Please continue reading Figure 1 ,like Figure 1 As shown in P1, on the first surface 11a of the PI film, one end of the first wiring 111 is connected to the temperature control component 120, the other end of the first wiring 111 is connected to the first electrode 130, one end of the second wiring 112 is connected to the temperature control component 120, and the other end of the second wiring 112 is connected to the second electrode 140, so that a heating circuit can be formed on the first surface 11a of the PI film through the first electrode 130, the first wiring 111, the temperature control component 120, the second wiring 112 and the second electrode 140. When the first electrode 130 is connected to the positive pole of the power supply and the second electrode 140 is connected to the negative pole of the power supply, the heating circuit generates heat through the first wiring 111 and the second wiring 112 to achieve the heating function; the heating circuit controls the heat generated by the first wiring 111 and the second wiring 112 through the temperature control component 120 to achieve the automatic temperature control function.

[0054] like Figure 1 As shown in P2, on the second side 11b of the PI film, the conductive area 113 is connected to the third electrode 150. When the third electrode 150 is connected to the electrical signal interface of an external electronic device (such as a physiotherapy device host) and the second side 11b of the PI film is attached to the skin, the conductive area 113 receives the electrical signal and transmits the electrical signal to the skin to achieve a physiotherapy function.

[0055] Among them, etching is a technology that uses chemical reactions or physical impact to remove part of the material. Therefore, after etching the first side 11a of the PI film to form the first trace 111 and the second trace 112, the thickness of the heating circuit formed based on the first trace 111 and the second trace 112 is only the sum of the thickness of the PI film and the thickness of a PTC thermistor; after etching the second side 11b of the PI film to form the conductive area 113, the thickness of the structure on the heating electrode patch 10 that realizes the heating function, automatic temperature control function and physical therapy function is only the sum of the thickness of the PI film and the thickness of a PTC thermistor, thereby reducing the overall thickness of the heating electrode patch 10, making it easier to fit the skin, and based on the characteristics of the PI film 110 that is resistant to high temperature, chemical corrosion and good insulation, there is no interference between the circuit structures formed on the first side 11a of the PI film and the second side 11b of the PI film and the functions realized respectively.

[0056] In the embodiment of the present application, a heating circuit capable of automatic temperature control is obtained by connecting a thinner PTC thermistor, a first trace 111 formed by etching a PI film 110, and a second trace 112, so that the structure realizing the automatic temperature control function and the heating function on the heating electrode patch 10 is relatively thin; a conductive area 113 is formed by etching on the second side 11b of the PI film, so that the physical therapy function is realized by transmitting an electrical signal to the human skin through the conductive area 113, so that the structure realizing the physical therapy function on the heating electrode patch 10 is relatively thin; a heating circuit capable of automatic temperature control is obtained by obtaining on the first side 11a of the PI film, and a conductive area 113 is formed by etching on the second side 11b of the PI film, so that the automatic temperature control function, the heating function, and the physical therapy function can be realized on one PI film 110, thereby reducing the overall thickness of the heating electrode patch 10.

[0057] It should be noted that the embodiment of the present application does not specifically limit the arrangement of the first routing line 111 and the second routing line 112 on the first surface of the PI film 110, nor does it limit the specific shape of the conductive area 113. The arrangement of the first routing line 111 and the second routing line 112 on the first surface of the PI film 110 and the shape of the conductive area 113 can be set according to actual use needs. For example, in order to ensure that the heat generated by the first routing line 111 and the second routing line 112 on the PI film 110 is sufficient, a curved and circuitous routing line (for example, an "S" shape) can be etched on the PI film 110 to extend the length of the first routing line 111 and the second routing line 112. Specifically, refer to Figure 3 The arrangement of the first wiring 111 and the second wiring 112, wherein, Figure 3 The schematic diagram of the structure of the first surface of the PI film provided in the embodiment of the present application is shown; for example, the second surface 11b of the PI film can be etched to form a Figure 1The square area shown by P2 in the figure can reduce the etching difficulty of the conductive area 113 and enable the electrical signal to be evenly transmitted to the skin by the conductive area 113.

[0058] See also Figure 4 , Figure 4 An exploded view of the heating electrode patch provided in an embodiment of the present application is shown. Figure 4 P1 is an exploded view of the heating electrode patch 10 from a top view. Figure 4 P2 is an exploded view of the heating electrode patch 10 from an upward perspective. The heating electrode patch 10 also includes a first layer 160 and a second layer 170; the first layer 160 is disposed on the first surface 11a of the PI film and covers the first wiring 111, the second wiring 112 and the temperature control component 120; the second layer 170 is disposed on the second surface 11b of the PI film and covers the conductive area 113.

[0059] Exposing the heating circuit and the conductive area 113 on the PI film 110 to the outside may easily cause safety hazards. Figure 4 As shown in P1, a first layer 160 may be provided on the first surface 11a of the PI film, so that the first wiring 111, the temperature control component 120 and the second wiring 112 in the heating circuit are covered by the first layer 160; Figure 4 As shown in FIG. 1 , a second layer 170 may be provided on the second surface 11 b of the PI film so that the conductive area 113 is covered by the second layer 170 , thereby improving the safety of the heat generating electrode patch 10 .

[0060] In an optional manner, the first layer 160, the PI film 110 and the second layer 170 can be arranged to have the same shape and size, so that the first layer 160 fully covers the first surface 11a of the PI film, and the second layer 170 fully covers the second surface 11b of the PI film, thereby further improving the safety of the heating electrode patch.

[0061] In an optional manner, the first layer 160 is a substrate layer formed of a flexible heat-insulating material, and the second layer 170 is a film made of a gel material. Specifically, the first layer 160 can be set to be silicone, and the second layer can be set to be hydrogel. Setting the first layer 160 as a substrate layer formed of a heat-insulating material can reduce the loss of heat generated by the first surface 11a of the PI film transferred to the air, so that the heat of the heating circuit can be transferred to the skin as much as possible; setting the first layer 160 as a substrate layer formed of a flexible material can make the heating electrode patch 10 fit the skin as much as possible; setting the second layer 170 as a gel material can make the heating electrode patch 10 adhere to the skin and evenly transfer the electrical signal of the conductive area 113 to the skin.

[0062] It should be noted that the embodiment of the present application does not specifically limit the fixing method of the first layer 160 and the second layer 170. For example, the first layer 160 can be fastened to the first surface 11a of the PI film, and the second layer 170 can be bonded to the second surface 11b of the PI film.

[0063] In the heating electrode patch 10, the first electrode 130, the second electrode 140 and the third electrode 150 can be arranged in a variety of ways. In the embodiment of the present application, the embodiment of the present application is explained by taking the first electrode 130, the second electrode 140 and the third electrode 150 as button electrodes 180, or the first electrode 130, the second electrode 140 and the third electrode 150 as wires as an example.

[0064] When the first electrode 130, the second electrode 140 and the third electrode 150 are all wires, please continue to refer to Figure 4 One end of the first electrode 130 is fixed to the first surface 11a of the PI film, connected to the other end of the first wiring 111, and the other end of the first electrode 130 is used to connect to the positive electrode of the power supply; one end of the second electrode 140 is fixed to the first surface 11a of the PI film, connected to the other end of the second wiring 112, and the other end of the second electrode 140 is used to connect to the negative electrode of the power supply; one end of the third electrode 150 is fixed to the second surface 11b of the PI film, connected to the conductive area 113, and the other end of the third electrode 150 is used to connect to the electrical signal interface.

[0065] The method of fixing the wires on the PI film 110 can be selected according to actual use needs. For example, the wires can be welded on the PI film 110 or bonded on the PI film 110 .

[0066] In an optional manner, the portions of the first electrode 130 and the second electrode 140 covered by the first layer 160 are bare wires, and the portions of the first electrode 130 and the second electrode 140 not covered by the first layer 160 are insulated wires. Similarly, the portion of the third electrode 150 covered by the second layer 170 is a bare wire, and the portion of the third electrode 150 not covered by the second layer 170 is an insulated wire.

[0067] The button electrode 180 includes an electrode male buckle 181, an electrode bottom buckle 182, and an electrode female buckle.

[0070] Furthermore, the embodiment of the present application also provides a connection method between electrodes and wiring when button electrodes are used. Figure 6 The structure diagram of the PI film provided in the embodiment of the present application is shown. Figure 6 P1 shows the schematic diagram of the structure of the first side of the PI film. Figure 6 P2 in FIG. 1 shows a schematic diagram of the structure of the second side of the PI film. Figure 6The first side 11a of the PI film is also etched to form a first coil 114 and a second coil 115, and the second side 11b of the PI film is also etched to form a third coil 116; the inner wall of the first coil 114 is connected to the electrode bottom buckle of the first electrode 130, the outer wall of the first coil 114 is connected to the other end of the first wiring 111, the inner wall of the second coil 115 is connected to the electrode bottom buckle of the second electrode 140, and the outer wall of the second coil 115 is connected to the other end of the second wiring 112, so that a passage is formed between the first electrode 130, the temperature control component 120 and the second electrode 140; the inner wall of the third coil 116 is connected to the electrode bottom buckle of the third electrode 150, and the outer wall of the third coil 116 is connected to the conductive area 113.

[0071] Compared with the point contact connection between the first wiring 111 and the electrode bottom buckle 182 of the first electrode 130, the first wiring 111 is connected through the outer wall of the first coil 114, and the inner wall of the first coil 114 is connected to the electrode bottom buckle 182 of the first electrode 130 to form a surface contact connection, which can increase the contact area between the heating circuit on the PI film 110 and the first electrode 130; the second coil 115 and the third coil 116 are set for a similar reason and will not be repeated.

[0072] The embodiment of the present application improves the contact stability between the heating circuit and the first electrode 130 and the second electrode 140 respectively by increasing the contact area between the heating circuit on the PI film 110 and the first electrode 130, and between the heating circuit on the PI film 110 and the second electrode 140; and improves the contact stability between the conductive region 113 and the third electrode 150 by increasing the contact area between the conductive region 113 and the third electrode 150.

[0073] According to another aspect of the embodiment of the present application, a physical therapy apparatus is provided. Figure 7 The structure diagram of the physiotherapy apparatus provided in the embodiment of the present application is shown in FIG. Figure 7 The physiotherapy device 1 includes a host 20 and a heating electrode patch 10 as described in any of the above embodiments; the positive power interface 21 of the host 20 is connected to the first electrode 130 of the heating electrode patch 10, and the negative power interface 22 of the host 20 is connected to the second electrode 140 of the heating electrode patch 10, for supplying power to the heating electrode patch 10; the pulse interface 23 of the host 20 is connected to the third electrode 150 of the heating electrode patch 10, for transmitting a pulse signal to the third electrode 150.

[0074] Among them, the pulse signal is a short and sudden electrical signal, usually with a fast rise and fall time characteristics. In form, it can be a square wave, a spike wave or other sudden waveform. The characteristic of pulse signals is that they are discrete in time, that is, they only occur once or several times in a period of time.

[0075] In physical therapy, nerves or muscles can be stimulated by pulse signals, which can be used in treatment methods such as neuromuscular electrical stimulation or transcutaneous electrical nerve stimulation. By precisely controlling the width, frequency, amplitude, and waveform of the pulses, physical therapists can target specific treatment goals, such as relieving pain, promoting blood circulation, or enhancing muscle function. These pulse signals are transmitted through the skin to the nerves and muscles in the body to produce the desired therapeutic effect.

[0076] When the first electrode 130, the second electrode 140 and the third electrode 150 are all button electrodes 180, please refer to Figure 7 In P1, when in use, the electrode female buckles on each interface of the host 20 need to be buckled with the electrode male buckles on the heating electrode patch 10; when the first electrode 130, the second electrode 140 and the third electrode 150 are all wires, please refer to Figure 7 In P2, when in use, the various interfaces on the host 20 need to be connected to the wires on the heating electrode patch 10.

[0077] By connecting the positive power interface 21 of the host 20 to the first electrode 130 of the heating electrode patch 10, and connecting the negative power interface 22 to the second electrode 140 of the heating electrode patch 10, the heating electrode patch 10 is powered by the host 20, thereby realizing the heating function and automatic temperature control function of the heating electrode patch 10; by connecting the pulse interface 23 to the third electrode 150 of the heating electrode patch 10, a pulse signal is transmitted to the third electrode 150 through the host 20, thereby realizing the physical therapy function of the heating electrode patch 10.
