Separate energy application devices have a separate main unit and actuator, allowing the main unit to be flexibly used with different actuators. However, the main unit of existing separate energy application devices is relatively large and has limited usage time, hindering their further widespread application.

[0030] In various embodiments of this application, the energy application device can refer to a device used to apply a certain form of energy to a user to produce a health care effect. The applied energy can be electrical pulses, which affect the human body to produce a health care effect. The applied energy can be heat, which heats parts of the human body to achieve certain health care effects, such as promoting blood circulation and removing blood stasis. The applied energy can also be mechanical vibration, which vibrates and massages specific parts of the human body to produce a comfortable feeling and health care effect. In some embodiments, the energy application device can be a physical therapy device, or simply a physiotherapy device. A physiotherapy device can refer to a medical device that acts on the human body through physical factors to achieve the purpose of prevention, health care, and rehabilitation. Its core principle is to utilize the biological effects of physical energy such as electricity, light, heat, magnetism, ultrasound, and mechanical vibration to regulate human physiological functions and improve pathological states. Its functions include relieving pain, eliminating inflammation, promoting blood circulation, loosening adhesions, enhancing muscle strength, regulating nerve function, and accelerating tissue repair, and it has the characteristics of being non-invasive, highly safe, and having few side effects.

[0031] In some embodiments, this application relates to the field of medical devices, particularly the design and application of wearable heating low-frequency physiotherapy devices. This technology combines the principles of physical therapy and low-frequency electrotherapy, utilizing low-frequency current and thermal effects to treat the human body, and belongs to the intersection of medical electronic equipment, physiotherapy equipment, and smart wearable device technologies.

[0032] In some embodiments, wearable low-frequency physiotherapy devices with heating functions can be modular. Modular heating low-frequency physiotherapy devices are typically large in size or have a short continuous heating time.

[0033] In some embodiments, this application provides a wearable heating low-frequency physiotherapy device, characterized by: 1. being a split type, which can be used with electrode pads or with accessories such as a waist belt; 2. being thin and small in size, with a special arc design that makes it easy for users to wear; 3. having a long working time, with an optimized structural stacking that makes it last longer than other products of the same size.

[0034] In some embodiments, this application aims to address the problems of poor flexibility in integrated heating therapy devices and short usage time and large size in split-type heating therapy devices. In some embodiments, this application combines the portability of integrated heating therapy devices with the flexibility of split-type devices.

[0035] Figure 1 A schematic diagram of the main unit of an energy application device according to an embodiment of this application is shown.

[0036] like Figure 1 As shown, the main unit 100 of the energy application device includes a housing 110, a circuit board 130, and a connector 120. The circuit board 130 is disposed inside the housing 110, and the connector 120 is fixedly connected to the circuit board 130. A portion of the structure of the connector 120 is exposed outside the housing 110. The connector 120 is used to connect the main unit 100 to the execution component of the energy application device. When the connector is physically connected to the housing of the main unit, the housing needs to be provided with axial (thickness direction of the housing) and radial limiting / fixing structures for the connector. This structure is generally such that the axial dimension of the connector is greater than the thickness of the connector. In this application, the connector is fixed to the PCB, so there is no need to provide axial and radial limiting / fixing structures inside the housing, thus occupying internal space and increasing the available space for accommodating the battery. Therefore, the battery volume can be increased to increase the working time. According to this embodiment, the connector is fixed to the circuit board, so that the connector can perform both mechanical connection functions and signal transmission or electrical connection functions. The connector is directly fixed to the circuit board, so that there is no need for other cables to connect the connector and the circuit board. This connection method can save space between the connector and the circuit board. This design allows for a smaller main unit with the same internal space. In other words, a main unit of the same size has more space inside to house the battery, allowing for a larger battery with greater capacity, thus enabling the energy delivery device to operate for a longer period.

[0037] In this embodiment, the host unit can refer to the part of the energy application device primarily used for generating energy and controlling related signals. For example, the host unit can be a part equipped with a battery and a circuit board. The battery is used to provide the corresponding current (such as heating current or current for generating pulse stimulation) to the actuator. The circuit board can receive signals from user input or feedback from the actuator and generate corresponding control-related signals.

[0038] In this embodiment, a connector refers to a component used for connection. Such a component can function as a connector independently or in conjunction with other connectors to achieve a connection. In this embodiment, a detachable connection refers to a connection that can be separated without damaging the structure of the connector or other components, and can be reconnected without structural damage. Detachable connections can take the form of snap-fit ​​connections, magnetic connections, nylon snap connections, interference fit connections, press-fit connections, threaded connections, etc.

[0039] In this embodiment, a fixed connection can refer to a connection method in which the two connected components cannot move or rotate relative to each other, and their positional relationship is fixed. By forming a fixed connection between the connector and the circuit board, the connector cannot move relative to the circuit board, allowing the connector to be directly connected or conductive to electronic components on the circuit board. This saves on connection structures and increases internal space.

[0040] As an example, connector 120 forms an electrical connection with the circuitry in circuit board 130. According to this example, by establishing an electrical connection between the connector and the circuitry on the basis of a fixed connection, the connector can simultaneously perform both mechanical and electrical connection functions. Since the connector is directly fixed to the circuit board, the electrical connection between the connector and the circuit board does not require additional cables, saving space between the connector and the circuit board and increasing the internal space of the host unit.

[0041] As an example, the circuit includes control-related circuitry and operating circuitry. According to this example, the control-related circuitry controls the actuator, and the operating circuitry performs the functions of the actuator. For example, the control-related circuitry can transmit feedback current capable of providing user temperature information, and the operating current can transmit pulse current or heating current to achieve the electro-pulse stimulation and heating functions of the actuator. By enabling the connectors to form direct electrical and mechanical connections with the circuit board, internal space in the host unit can be saved to accommodate a larger battery, thereby extending operating time.

[0042] As an example, connector 120 and circuit board 130 are electrically and physically connected by direct engagement. According to this example, by making the connector and circuit board directly engaged, there is no need to create a gap between the connector and the circuit board. This arrangement helps to save internal space, increases the internal space of the host, thereby allowing for miniaturization of the host, and allows for the installation of a larger capacity battery inside the host, thus increasing the usage time.

[0043] As an example, connector 120 is welded, riveted, or bonded to circuit board 130 to form a fixed connection and / or electrical connection. Welding, riveting, or bonding the connector to the circuit board allows it to be securely fixed to the board while achieving a reliable electrical connection, saving space between the connector and the circuit board and increasing the space available inside the main unit to accommodate the battery.

[0044] As an example, housing 110 is provided with window 111, which connects the interior and exterior of housing 110. A portion of the structure of connector 120 is exposed outside housing 110 via this window. According to this example, the connector needs to be connected to an actuator, therefore a portion of its structure needs to be exposed outside the housing. By providing a window on the housing, the connector can be directly exposed to the outside through the window, thereby connecting to the actuator.

[0045] Figure 2 A schematic diagram of an energy application device according to an embodiment of this application is shown.

[0046] like Figure 2 As shown, the main unit 201 of the energy application device 200 includes a housing 210, a circuit board 230, and a connector 220. The circuit board 230 is disposed inside the housing 210. The connector 220 is fixedly connected to the circuit board 230, and a portion of the connector 220 is exposed outside the housing 210. The connector 220 is used to connect the main unit 201 to the execution component 202. The main unit 201 generates operating current and control-related current, and the execution component 202 and the main unit 201 conduct operating current and control-related current through the connector 220. According to this embodiment, the connector not only enables a detachable connection between the main unit and the execution component, but also enables the main unit to transmit operating current and control-related current to the execution component. This arrangement makes the split-type energy transfer device more compact and miniaturized, and increases the internal space of the main unit of the energy transfer device without increasing the overall size, thereby allowing for the installation of a larger capacity battery and extending the usage time.

[0047] In this embodiment, in the energy application device, the host unit generates an operating current or a control current, and the execution component receives the operating current or control-related current generated by the host unit, thereby applying controlled energy to the user. The connector is capable of conducting such operating or control current, enabling not only a mechanical connection between the host unit and the execution component but also an electrical connection to perform specific functions.

[0048] As an example, the operating current includes pulse current, heating current, or excitation current; correspondingly, the actuating component 202 is a massage device driven by an electric pulse device, an electric heating device, or an excitation current. According to this example, the energy application device can be in the form of a physical therapy device. A physical therapy device employing the features of the energy application device of this application can better provide physical therapy to the user. Such a physical therapy device can be mounted on an electric pulse device (e.g., electrode pads) attached to the user's body with a more compact main unit, thus making it more convenient to perform physical therapy. In addition, such a physical therapy device can accommodate a larger and higher-capacity battery, providing a longer operating time, thereby adapting to various application scenarios. In some embodiments, the electric pulse device is a means for implementing pulse stimulation function. In some embodiments, the electrode pads can be an integration of the electric pulse device and the electric heating device. In some embodiments, the energy application device can be in the form of a massage device. A massage device employing the features of the energy application device of this application can better provide massage to the user. The main unit of such a massage device is more compact and can be detachably connected to the massage device as the actuating component. In addition, the main unit of such a massager has a larger internal space, which can accommodate a larger and more powerful battery, resulting in a longer usage time. This allows the massager to work for a longer period of time, thus providing a more thorough massage to the user.

[0049] Figure 3 A schematic diagram of an energy application device according to an embodiment of this application is shown.

[0050] like Figure 3 As shown, the main unit 301 of the energy application device 300 includes a housing 310, a circuit board 330, and a connector 320. The circuit board 330 is disposed inside the housing 310; the connector 320 is fixedly connected to the circuit board 330, and a portion of the structure of the connector 320 is exposed outside the housing 310. The connector 320 is used to connect the main unit 301 to the execution component 302 of the energy application device. In this embodiment, the connector 320 is a female magnetic snap 321, and the execution component 302 is provided with a male magnetic snap 322. The female magnetic snap 321 and the male magnetic snap 322 form a magnetic snap pair, and the main unit 301 is detachably connected to the execution component 302 through the magnetic attraction between the female magnetic snap 321 and the male magnetic snap 322. According to this embodiment, the detachable connection achieved by magnetic attraction has the advantages of convenient disassembly and stable connection. The magnetic snap fastener enables a detachable connection between the host and the actuator, allowing for easy contact and connection between them. Furthermore, the host and actuator can be easily detached with slight force, facilitating convenient and quick assembly and disassembly. In an optional embodiment, the female magnetic snap fastener 321 can be located in the actuator 302, while the male magnetic snap fastener 322 is located in the host 301.

[0051] In this embodiment, a magnetic snap fastener refers to a fastener that uses the attractive force between magnetic materials to achieve a connection and fixation function. Its core structure consists of a female and a male snap fastener, each embedded with a permanent magnet (such as a neodymium iron boron magnet) and a magnetic material (such as iron), respectively. The fastening is achieved by the attraction of opposite magnetic poles. Magnetic snap fasteners come in various shapes, commonly circular, strip-shaped, or irregularly shaped. Their surfaces can be covered with protective layers such as plastic (without affecting the reliability of the electrical connection) or metal to enhance durability and safety. Magnetic snap fasteners offer advantages such as convenient connection, minimal wear, and repeated disassembly, combining functionality with design flexibility.

[0052] As an example, the female magnetic snap 321 comprises a permanent magnet material and the male magnetic snap 322 comprises a magnetic material, or the female magnetic snap 321 comprises a magnetic material and the male magnetic snap 322 comprises a permanent magnet material. According to this example, one of the female magnetic snap on the host and the male magnetic snap on the actuator is a permanent magnet, and the other is a magnetic material such as a ferromagnetic material. Magnetic attraction achieved through a permanent magnet does not require the application of electricity, thus ensuring the stability and reliability of the magnetic attraction. The magnetic force between the permanent magnet material and the magnetic material allows for a stable, secure, and detachable connection between the host and the actuator, which can be achieved without electricity, making it convenient and quick. Such magnetic snaps are easy to implement.

[0053] As an example, there are multiple connectors 320. Some of the connectors 320 are used to conduct operating current, while others are used to conduct control-related current. According to this example, by using different connectors to transmit the operating current and the control-related current, the transmission of the operating current and the control-related current does not interfere with each other, allowing for stable and reliable transmission of both currents in a simple and easy manner. The connectors (e.g., magnetic snap-fits) can be made of conductive materials, and the transmission of operating current and control-related current is achieved through these connectors.

[0054] Figure 4 A schematic diagram of an energy application device according to an embodiment of this application is shown.

[0055] like Figure 4As shown, the main unit 401 of the energy application device 400 includes a housing 410, a circuit board 430, and a connector 420. The circuit board 430 is disposed inside the housing 410; the connector 420 is fixedly connected to the circuit board 430, and a portion of the structure of the connector 420 is exposed outside the housing 410. The connector 420 is used to connect the main unit 401 to the execution component 402 of the energy application device. The main unit 401 generates operating current and control-related current, and the execution component 402 is connected to the main unit via the connector 420 to conduct the operating current and control-related current. The control-related current includes a feedback current, which characterizes the temperature information of the part of the user to which energy is applied. According to this embodiment, the temperature of the electrode pads characterizes the user's temperature. By transmitting the temperature information of the electrode pads to the main unit, the main unit can dynamically adjust the applied energy, i.e., heat, according to the temperature of the electrode pads, so that the applied energy can adapt to the user's real-time physical state, avoiding inappropriate energy application that could reduce the health benefits or even harm the user's body. The user's temperature information is transmitted to the host via a connector, enabling the host and electrode plates to transmit temperature information in a simple and reliable manner. This avoids the increased size of the host caused by complex transmission components, which would lead to inconvenience in use.

[0056] In this embodiment, the user's temperature information can refer to the temperature of the user's skin or the body part of the user's body to which the electrode pads are attached. The user's temperature information is, for example, measured by the energy application device through a temperature measuring component in the electrode pad. The electrode pad is electrically connected to the host unit, so the electrode pad can transmit temperature information to the host unit via a magnetic snap-fit ​​connection between the host unit and the electrode pad. This allows the host unit to control the applied energy, such as heat, based on the user's temperature information measured in real time by the electrode pad, ensuring both the health benefits and the user's comfort.

[0057] As an example, connector 420 includes a female magnetic snap 421, and actuator 402 includes a male magnetic snap 422. The female magnetic snap 421 and male magnetic snap 422 form a magnetic snap pair. Host 401 is detachably connected to actuator 402 through the magnetic attraction between the female magnetic snap 421 and male magnetic snap 422. The magnetic snap pair includes at least one first magnetic snap pair 440 and at least one second magnetic snap pair 450. Host 401 and actuator 402 transmit pulse current through at least one first magnetic snap pair 440 and heating current through at least one second magnetic snap pair 450. The magnetic snap pair also includes at least one third magnetic snap pair 460, and actuator 402 and host 401 transmit feedback current through at least one third magnetic snap pair 460. According to this example, pulse current, heating current, and feedback current are transmitted through different magnetic snap pairs, enabling stable and reliable transmission of various signals and currents. This simplifies the design of the transmission device and reduces structural costs. A special magnetic clasp is used to transmit feedback current containing temperature information, ensuring a stable and reliable path for this information to be transmitted to the main unit. The temperature information received by the main unit is accurate, allowing it to dynamically adjust the heating current based on the user's body temperature, thus ensuring therapeutic effects and user comfort.

[0058] As an example, at least one second magnetic snap pair 450 and at least one third magnetic snap pair 460 share at least one magnetic snap pair. According to this example, sharing a single magnetic snap pair for transmitting heating current and for transmitting temperature information simplifies the structure. By reusing the connectors, the same magnetic snap pair can transmit both heating current and temperature information, thus reducing the number of magnetic snap pairs required, lowering overall manufacturing costs, and improving the economic efficiency of the main unit of the energy application device.

[0059] Figure 5 A schematic diagram of the main unit of an energy application device according to an embodiment of this application is shown.

[0060] like Figure 5 As shown, the main unit of the energy application device is roughly disc-shaped, with its outline consisting of arcs on both sides and straight lines at the top and bottom. Buttons are located on the upper surface of the main unit for user operation, and its outer casing is covered with a soft rubber material.

[0061] As an example, the main unit's outline includes a rounded shape, and / or the casing is covered with a soft rubber material. Covering the casing with a soft rubber material further enhances the comfort of the main unit against the skin, making it more pleasant to the user and improving its acceptance and usability. When using a soft rubber material to cover the casing, physical buttons are not required; the soft rubber material itself can be used to create button areas for pressing switches on the circuit board. The casing only needs an opening that allows the button area to directly contact the switches when pressed. This reduces the design and manufacturing complexity of incorporating movable buttons into a thinner casing.

[0062] Figure 6 Showing according to Figure 5 A schematic diagram of the main unit of the energy application device in the embodiment.

[0063] like Figure 6 As shown, five magnetic snaps are provided on the lower surface of the main unit, including two first magnetic snaps 510, two second magnetic snaps 520, and one third magnetic snap 530. The two first magnetic snaps 510 are used to transmit pulse current, and the two second magnetic snaps 520 are used to transmit heating current. The third magnetic snap 530 and one of the second magnetic snaps 520 are used to transmit temperature information, which means that one second magnetic snap 520 is used for both transmitting heating current and transmitting temperature information; that is, one second magnetic snap 520 is multiplexed.

[0064] Figure 7 Showing according to Figure 5 An exploded view of the main unit of the energy application device in the embodiment.

[0065] like Figure 7 As shown, the main unit of the energy application device includes, from top to bottom, an upper cover 511, an upper PCB 512, a battery 513, a lower PCB 514, a lower cover 515, and multiple magnetic snaps (a first magnetic snap 510, a second magnetic snap 520, and a third magnetic snap 530).

[0066] According to this embodiment, the stacking structure of the host is as follows: Figure 7 As shown. The upper PCB 512 is fixed to the upper cover 511, and the lower PCB 514 is fixed to the lower cover 515 after the magnetic buckle and main control chip are soldered on. The battery 513 is located between the two PCBs. The exterior is covered with soft rubber material 516.

[0067] Users operate the machine via buttons to turn it on / off, switch on / off heating, and switch on / off low-frequency therapy. The main control chip receives the button signals and transmits the corresponding heating / low-frequency signals to the corresponding electrode pads or waist belt via multiple magnetic clips. The temperature of the electrode pads and waist belt is then fed back to the main unit via these magnetic clips.

[0068] Figure 8 Showing according to Figure 5 A cross-sectional view of the main unit of the energy application device in the embodiment.

[0069] like Figure 8 As shown, multiple magnetic snaps are directly soldered to the lower PCB 514 to achieve physical and electrical connection with the host (instead of conventional connection to PCB lines or physical connection to the host housing). This improves integration, reduces space occupation, and increases the usable space of the battery 513, allowing the battery 513 to increase its volume and operating time. If the magnetic snaps are connected to PCB lines, space needs to be left between the PCB and the magnetic snaps to accommodate the lines / connectors. When the magnetic snaps are physically connected to the host housing, the host housing needs to have axial and radial limiting / fixing structures for the magnetic snaps. This structure generally requires the axial dimension of the magnetic snaps to be larger than the thickness of the magnetic snaps. In this embodiment, multiple magnetic snaps are fixed to the lower PCB 514, so the housing does not need to have a fixing structure. The multiple magnetic snaps pass directly through the window 517 of the lower cover 515 to be exposed outside the housing, which is equivalent to increasing the positioning between the lower PCB 514 and the lower cover 515 of the housing through the magnetic snaps.

[0070] In addition to the function of physical connection, the magnetic attraction is also a contact point for control signals, heating current, and pulse current. Multiple contacts respectively or jointly undertake the above three functions.

After reading this application, those skilled in the art can make any possible improvements, substitutions, and equivalents to the steps, methods, apparatus, and components in the above embodiments, and such improvements, substitutions, and equivalents should be considered to fall within the scope of this application.
