Detailed Implementation

[0011] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0012] In some of the processes described in the specification, claims, and accompanying drawings of this application, multiple operations appearing in a specific order are included. However, it should be clearly understood that these operations may not be executed in the order they appear herein, or may be executed in parallel. The operation numbers, such as 101, 102, etc., are merely used to distinguish different operations and do not themselves represent any execution order. Furthermore, these processes may include more or fewer operations, and these operations may be executed sequentially or in parallel. It should be noted that the descriptions such as "first," "second," etc., in this document are used to distinguish different messages, devices, modules, etc., and do not represent a chronological order, nor do they limit "first" and "second" to different types.

[0013] The technical solutions of this application can be applied to various nursing devices with nursing functions, such as beauty instruments, massage instruments, eye beauty instruments, contact lens instruments, eyebrow drawing instruments, and other nursing devices that can perform different nursing functions on the human body, such as beauty, nursing, acupuncture, slimming, detoxification, stress relief, etc. This application does not impose specific limitations on them.

[0014] The object of care in this application embodiment may refer to human skin, such as facial skin, neck skin, hand skin, etc., or it may refer to characteristic parts of the human body, such as feet, legs, shoulders and neck, etc.

[0015] Taking beauty devices as an example, a beauty device is a machine that can adjust and improve the body and face according to the physiological functions of the human body. Its corresponding care objects can refer to the skin of the human body, such as the skin around the eyes and the skin on the face. Beauty devices can come into contact with the skin and perform care activities on the skin, such as cleansing, wrinkle removal, skin tightening, reducing fine lines, dark circles and dark bags, and assisting in the absorption of skin care products.

[0016] Current beauty devices typically consist of a head structure and a body. The head structure has operating surfaces for contact with the recipient. However, due to limitations in technique, pressure, and the recipient's individual needs, existing devices often fail to conform well to the recipient, thus affecting the treatment's effectiveness. In developing this application, the inventors discovered that the head structure and body of current beauty devices are usually fixed. Even some devices with adjustable head structures require manual adjustment, still failing to guarantee effective contact with the recipient.

[0017] To achieve effective fit with the patient and ensure nursing efficacy, the inventors, after a series of studies, proposed the technical solution of this application. In the embodiments of this application, the main body of the nursing device consists of a first body and a second body. A rotating component is fixed on the first body, and the second body has an extended end sleeved in the rotating component. The second body can rotate relative to the first body within a preset angle range via the rotating component. The second body rotates around a rotation axis as a fulcrum, and the symmetrical force-bearing points on both sides of the rotation axis form an equal-arm lever. Through the rotating component of this embodiment, utilizing the lever principle, the second body can be freely adjusted without manual adjustment, ensuring effective fit with the patient and guaranteeing nursing efficacy.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] like Figure 1 The diagram shown is a structural schematic of one embodiment of a nursing device provided in this application. The nursing device may include: a control system 101, at least one nursing system 102 connected to the control system 101, and at least one detection system 103. The at least one detection system 103 can be used to detect the nursing object. The detection system 103 is connected to the control system 101 and can receive corresponding control commands from the control system 101 to detect the nursing object. The at least one nursing system 102 can be used to provide care to the nursing object. The nursing system 102 is connected to the control system 101 and can receive corresponding control commands from the control system 101 to provide care to the nursing object. The control system 101 can use the at least one detection system 103 to detect the nursing object and obtain at least one state parameter value; based on the at least one state parameter value, it controls the operation of the at least one nursing system 102.

[0020] The nursing device can be a device that provides nursing functions using at least one nursing system and can perform nursing care on a subject, such as a beauty device or a massage device. Taking a beauty device as an example, the subject of nursing care can be the user's skin, and the beauty device can perform nursing activities on the user's skin. Taking a massage device as an example, the subject of nursing care can be a characteristic area of ​​the user, such as the shoulders, neck, or limbs. In one or more embodiments below, the technical solutions of the embodiments of this application are described primarily using a beauty device as the nursing device.

[0021] The nursing device includes at least one nursing system and performs nursing activities based on at least one nursing system. Optionally, taking a beauty device as an example, the at least one nursing system may include one or more of a microcurrent nursing system, a vibration nursing system, an optical nursing system, a radio frequency nursing system, and a cold / hot compress nursing system. Specifically, the optical nursing system can use special wavelengths of light such as red, green, and blue light to irradiate the target of the nursing, i.e., the user's skin, for nursing; the microcurrent nursing system can use microcurrents to stimulate the user's skin for nursing; the vibration nursing system can use a vibration motor to vibrate and massage the user's skin for nursing; the radio frequency nursing system can use radio frequency technology for nursing; and the cold / hot compress nursing system can use cold / hot compresses for nursing, etc.

[0022] At least one of the care systems is connected to the control system and operates under its control. In practical applications, the control system can be implemented as a microcontroller unit (MCU), microprocessor, or single-chip microcomputer. Optionally, taking a beauty device as an example, the detection system included in the device may include one or more of a moisture detection system, an elasticity detection system, an oil content detection system, and a skin whiteness detection system. Specifically, the moisture detection system can be used to detect the user's skin moisture; the elasticity detection system can be used to detect the user's skin elasticity; the oil content detection system can be used to detect the user's skin oil content; and the skin whiteness detection system can be used to detect the user's skin whiteness, etc.

[0023] Optionally, the control system can control at least one detection system to operate and detect the object being cared for based on a detection start command. This detection start command can be triggered by a user, in which case the control system can control at least one detection system to operate and detect the object being cared for based on the user-triggered detection start command. Taking a beauty device as an example, the control system can control a moisture detection system to operate and detect the user's skin moisture level based on a user-triggered moisture detection start command. The operating time of the at least one detection system is not limited; for example, completing a moisture detection can take three seconds.

[0024] To ensure the normal operation of the care device, in some embodiments, the control system can also output a first prompt message based on the detection start command; this first prompt message can be used to remind the user of the operating procedures. Taking a beauty device as an example, where the care object is the user's facial skin, the user needs to correctly position the beauty device to ensure proper contact between the device and the facial skin for skin detection and care. In this case, the first prompt message can include operating procedures such as the method and steps for using the beauty device, such as "Please place the beauty device on the left side of your face." The control system can output the first prompt message in the form of voice broadcast, or in the form of display such as text, animation, or video, or even as a vibration reminder, etc. This application does not specifically limit this.

[0025] By using at least one of the aforementioned detection systems to detect the subject, at least one state parameter value can be obtained. This at least one state parameter value may include one or more of the following: moisture parameter value, elasticity parameter value, oil content parameter value, and skin whiteness parameter value. The state parameter value represents the state type, such as moisture, elasticity, oil content, or skin whiteness. The state parameter value can be the state value itself, such as moisture or elasticity value; alternatively, it can be other parameter values ​​that represent the state type, such as pressure, current, or voltage values. One detection system can detect one state type and obtain the corresponding state parameter value. For example, using a moisture detection system to detect a user's skin can obtain a moisture parameter value. Similarly, using an elasticity detection system to detect a user's skin can obtain an elasticity parameter value. In practical applications, the detection system and state parameter values ​​can be set according to the actual scenario; no specific limitations are imposed here.

[0026] Once the control system obtains at least one state parameter value, it can control the operation of at least one nursing system based on that state parameter value. The specific control method will be described in detail in the following embodiments.

[0027] The nursing equipment in this embodiment can detect the nursing object through at least one detection system via the control system. Based on at least one state parameter value obtained from the detection, at least one nursing system can be controlled to operate, thereby achieving the purpose of targeted nursing for different nursing objects, which can greatly improve the nursing effect and achieve effective nursing.

[0028] As yet another example, such as Figure 2 As shown, with Figure 1The difference in the nursing device shown is that it may also include a communication system 105 connected to the control system 101 for establishing a connection with the control terminal 104. The control system 101 can receive corresponding instructions sent by the control terminal 104 in response to user-related operations through the communication system 105. The control terminal can be a client or a server connected to the nursing device. The client can be configured in a user device, such as a mobile phone, tablet, smartwatch, computer, or other smart terminal device, and may be an application (APP) in the user's smart terminal device. The server can be a cloud server. The communication system may include a Bluetooth component or a Wi-Fi component, and can connect to the control terminal via Bluetooth or Wi-Fi. The connection establishment method is the same as in traditional solutions and will not be described in detail here. The relevant operations involving the control terminal will be described in detail in the corresponding embodiments below.

[0029] In some embodiments, such as Figure 2 As shown, the nursing device may further include an interactive system 106 connected to the control system 101. The control system 101 can generate corresponding instructions by sensing user-related operations through the interactive system 106. This interactive system refers to a system that allows user interaction, enabling input / output of relevant information. For example, the interactive system may include a control panel, which may have at least one control button, such as a virtual button (OK), a reject button, a numeric button, a back button, or a physical button (Power button), for the user to touch to trigger different control commands. The control panel may also include a display area for displaying relevant content. In other embodiments, the interactive system may be a touchscreen display integrating operation control and display functions. The interactive system may also include an audio acquisition component to acquire user speech and recognize user operations through voice recognition or other methods. Furthermore, the interactive system may also include an audio playback component for outputting relevant content.

[0030] Furthermore, in some embodiments, after obtaining at least one state parameter value, the control system can generate a first detection result based on the at least one state parameter value and output a first result prompt message corresponding to the first detection result. The first detection result may include the at least one state parameter value. Of course, the control system can also compare the at least one state parameter value with a corresponding standard value to obtain difference information and / or status scores, etc. Specifically, the status score can be obtained by the control system based on the difference information and a preset score list. The first result prompt message can inform the user of the first detection result. The first result prompt message can be displayed and / or broadcast to the user through an interactive system, or it can be sent to the control terminal for the user to view, so that the user can understand their skin status type.

[0031] Optionally, the control system can also generate a second detection result based on at least one state parameter value and at least one historical state parameter value obtained from historical detection by at least one detection system; and output a second result prompt message corresponding to the second detection result. The second detection result can be state trend information determined by combining the state parameter value of a certain state type and historical state parameter values, such as an increase or decrease, for example, increased or decreased skin elasticity, decreased or increased skin moisture, etc. The second result prompt message can be used to prompt the second detection result, and can be displayed in the form of content and / or voice broadcast to provide feedback to the user through the interactive system. Alternatively, it can be sent to the control terminal for the user to view. In some embodiments, the control system can also be used to output nursing suggestions to the control terminal or interactive system for the user to view. The nursing suggestions can be determined by the control system based on the first or second detection result.

[0032] The control system can control the operation of at least one nursing system based on the at least one state parameter value in several ways. As an optional implementation, the control system can control the operation of at least one nursing system based on the at least one state parameter value by: determining the first nursing parameter value corresponding to each of the at least one nursing system based on the at least one state parameter value; and controlling the operation of at least one nursing system according to the first nursing parameter value corresponding to each of the at least one nursing system.

[0033] Different nursing systems can correspond to different nursing parameter types. Taking a beauty device as an example, for the microcurrent nursing system in this device, the nursing parameter type may include microcurrent intensity, etc.; for the vibration nursing system in this device, the nursing parameter type may include vibration frequency, etc.; for the optical nursing system in this device, the nursing parameter type may include light exposure time or intensity, etc. In the embodiments of this application, the nursing parameter value of the corresponding nursing parameter type can be determined based on the state parameter value.

[0034] The control system can control the operation of at least one nursing system according to the corresponding nursing parameter values. For example, if the nursing parameter value corresponding to the microcurrent nursing system is microcurrent intensity level one, the control system controls the operation of the microcurrent nursing system according to level one microcurrent intensity. Specifically, this can be achieved by sending a control command containing "microcurrent intensity level one" to the microcurrent nursing system, so that the microcurrent intensity applied to the user's skin by the microcurrent nursing system is level one. In other embodiments, if the nursing parameter value corresponding to the microcurrent nursing system is the current or voltage value of the microcurrent, the control system controls the operation of the microcurrent nursing system according to that current or voltage value. Specifically, this can be achieved by sending a control command containing a specific current or voltage value to the microcurrent nursing system, so that the microcurrent applied to the user's skin by the microcurrent nursing system is most suitable. A nursing parameter value can be determined by one or more state parameter values. For example, the microcurrent intensity can be determined based on the user's skin moisture level, or it can be determined based on both the user's skin moisture level and skin elasticity. In other implementations, users can manually adjust at least one nursing parameter value of the control system by using physical buttons or touch operation of the application software of a smart terminal wirelessly connected to the nursing equipment, according to the operation instructions in the product user manual or simple lookup table, thereby controlling the operation of at least one nursing system.

[0035] As an alternative implementation, the control system, based on at least one state parameter value, controls the operation of at least one nursing system. This can be achieved by: determining at least one first target nursing system based on at least one state parameter value; and controlling the operation of that first target nursing system. In other words, by combining at least one state parameter value, one or more corresponding nursing systems can be automatically selected from at least one nursing system for operation. For descriptive purposes, the nursing system determined based on at least one state parameter value can be referred to as the first target nursing system. In practical applications, different correspondences between different state parameter values ​​and different nursing systems can be pre-set, and by looking up these correspondences, the selection of which first target nursing systems to use can be determined.

[0036] Furthermore, the nursing equipment provided in this application embodiment can also support manual setting of nursing parameter values. Therefore, in some embodiments, the control system can also determine the second nursing parameter value corresponding to each of at least one nursing system based on the parameter setting command triggered by the user; and control the operation of at least one nursing system according to the nursing parameter value corresponding to each of the at least one nursing system. For ease of description and distinction, the nursing parameter value corresponding to each of the at least one nursing system determined by the control system based on at least one state parameter value can be referred to as the first nursing parameter value, and the nursing parameter value corresponding to each of the at least one nursing system determined by the control system based on the parameter setting command triggered by the user can be referred to as the second nursing parameter value. Therefore, the terms "first" and "second" in this description do not have any specific other meaning, but are only used for descriptive distinction. The implementation method of the user-triggered parameter setting command will be described in detail in the following embodiments, and will not be repeated here.

[0037] Furthermore, the nursing equipment provided in this application embodiment can also support manual selection of nursing systems. Therefore, in some embodiments, the control system can also determine at least one second target nursing system based on a first selection command triggered by the user. Thus, the control system can control the operation of at least one nursing system based on at least one state parameter value. Specifically, the control system can determine the nursing parameter values ​​corresponding to the at least one second target nursing system based on at least one state parameter value, and control the operation of the at least one second target nursing system according to the nursing parameter values ​​corresponding to the at least one second target nursing system. The first selection command can be determined by a user selection operation for at least one nursing system. Specifically, based on at least one nursing system, the user can select at least one second target nursing system for care. The implementation method of the user-triggered first selection command will be described in detail in the following embodiments and will not be repeated here.

[0038] In practical applications, nursing devices often comprise multiple nursing systems with different nursing effects. To further improve the nursing effect, in some embodiments, the control system can control at least one nursing system to operate sequentially based on at least one state parameter value. For example, taking a beauty device as an example, the control system can control the optical nursing system, microcurrent nursing system, and vibration nursing system to operate sequentially according to their respective order, based on at least one state parameter value. In other embodiments, the control system can control at least one nursing system to operate simultaneously based on at least one state parameter value. For example, taking a beauty device as an example, the control system can control the optical nursing system, microcurrent nursing system, and vibration nursing system to operate simultaneously based on at least one state parameter value.

[0039] Furthermore, when any nursing system finishes operation, the control system can also output nursing mode prompts based on the next nursing system to run. For example, when the microcurrent nursing system finishes operation, it can output prompts such as "The next procedure is vibration nursing" to clarify the subsequent nursing operation for the user. These nursing mode prompts can be output via an interactive system in the form of voice broadcast, or via a display, or by the control terminal in either form; this application does not specifically limit the specific methods used.

[0040] Optionally, the operating sequence of the nursing system can also be determined by the control system in conjunction with at least one state parameter value. Therefore, as another optional implementation, the control system controlling the operation of at least one nursing system based on at least one state parameter value can be: determining the operating sequence of at least one nursing system based on at least one state parameter value; and controlling at least one nursing system to operate sequentially according to the operating sequence. Taking a beauty device as an example, the at least one state parameter value may include, for example, the user's skin moisture parameter value, skin elasticity parameter value, etc. The control system can make judgments based on this at least one state parameter value. For example, if it is determined based on the moisture parameter value and elasticity parameter value that the user's skin moisture is low but skin elasticity is normal, then the microcurrent nursing system can be prioritized over the vibration nursing system; if the user's skin moisture is normal but skin elasticity is low, then the vibration nursing system can be prioritized over the microcurrent nursing system, and so on.

[0041] In some embodiments, the control system controlling the operation of at least one nursing system based on at least one state parameter value may involve: determining the nursing system to be switched based on a second selection command triggered by a user; and controlling the operation of the nursing system to be switched based on at least one state parameter value. Specifically, this may involve determining the nursing parameter value of the nursing system to be switched based on the at least one state parameter value, and then controlling its operation according to the nursing parameter value of the nursing system to be switched. The user may manually select the next nursing system to be run based on at least one nursing system. In this case, the control system may no longer control the at least one nursing system to run sequentially, but rather control the operation of the nursing system to be switched. The running time of each nursing system may be, for example, three minutes. The implementation method of the user triggering the second selection command will be described in detail in the following embodiments and will not be repeated here.

[0042] After the nursing system is operational, its nursing effects will be reflected in the patients receiving care. In practical applications, to facilitate users' understanding of the nursing effects after each care session, in some embodiments, the control system can also re-control at least one detection system to detect the patients after at least one nursing system has finished operating; based on at least one status parameter value obtained from the re-detection by at least one detection system, a third detection result is generated; and a third result prompt message corresponding to the third detection result is output. This third detection result may include at least one status parameter value, or difference information obtained by comparing at least one status parameter value with a corresponding standard value, a status score, etc., or trend information determined by at least one status parameter value and at least one historical status parameter value, or may include multiple data such as status parameter values, difference information, status scores, and trend information.

[0043] The nursing device may further include a storage system; the storage system stores one or more computer instructions; these instructions are used by the control system to call and execute the various operations involved in the embodiments of this application, such as controlling at least one detection system to detect the nursing object and controlling the operation of at least one nursing system. Specifically, the control system can use at least one detection system to detect the nursing object, obtain at least one status parameter value, and control the operation of at least one nursing system based on the at least one status parameter value. Of course, the control system may also store the one or more computer instructions itself without the need for an additional storage system.

[0044] In practical applications, the corresponding instructions acquired by the control system can be triggered by the user, such as the detection start instruction, first selection instruction, second selection instruction, parameter setting instruction, etc. mentioned above.

[0045] As described above, user-triggered commands can be implemented by a control terminal, which can be a client connected to the nursing equipment or a server. The client can be configured on the user's device, such as a mobile phone, tablet, smartwatch, or computer; for example, it can be an application (APP) on the user's smart terminal. The server can be a cloud server. The control terminal establishes a connection with the communication system, which can be achieved via Bluetooth, Wi-Fi, etc., in the same way as traditional solutions, and will not be elaborated further. The control terminal can include a display interface. The control system can also send corresponding data to the control terminal through the communication system, and the control terminal displays this data on the display interface. This display interface can be used to detect user actions and trigger corresponding commands.

[0046] For example, the first selection instruction can be specifically determined by the control terminal based on a first user selection operation targeting at least one nursing system. Alternatively, the user can directly input the at least one second target nursing system in the display interface, in which case the control terminal can determine a first selection instruction including the at least one second target nursing system based on the user's input.

[0047] As an alternative implementation, the user can select at least one second target nursing system from the selection prompts provided on the display interface, such as a list of at least one nursing system. The at least one nursing system can be provided by the control system to the control terminal. For example, the control system can send the selection prompts containing at least one nursing system to the control terminal so that the control terminal's display interface can show the selection prompts to the user, or the control terminal can provide them directly.

[0048] To facilitate user selection, in some embodiments, the control system can also determine at least one third target care system based on at least one state parameter value, and send recommendation prompts to the control terminal based on at least one third target care system. These recommendation prompts can be displayed on a screen, for example, as controls indicating whether to select the at least one third target care system. If the user selects the corresponding control, then the at least one third target care system becomes at least one second target care system. Alternatively, the recommendation prompts the user to select from the at least one third target care system; therefore, the first selection instruction can be triggered by the user performing a selection operation from at least one second target care system. Furthermore, the user can also refuse to select at least one second target care system from the at least one third target care system, or can select only a portion of the second target care systems from the at least one third target care system, etc., allowing the control terminal to generate the first selection instruction based on different user selection operations. The control system can receive the first selection instruction sent by the control terminal through a communication system. After receiving the first selection instruction, the control system can control the operation of at least one second target care system.

[0049] For example, the second selection instruction can be determined by the control terminal based on a second user selection operation for at least one nursing system. The implementation method for the user to select the nursing system to switch from at least one nursing system can refer to the implementation method for the user selecting at least one target nursing system described above, and will not be repeated here.

[0050] For example, the parameter setting instruction can be generated by the control terminal in response to the user's parameter setting operation. Specifically, the control system can send selection information containing different nursing parameter values ​​corresponding to at least one nursing system to the control terminal and display it on the display interface. The user can select a suitable nursing parameter value from the different nursing parameter values ​​corresponding to at least one nursing system. Based on the user's parameter setting operation, the control terminal can determine the parameter setting instruction for the second nursing parameter value corresponding to at least one nursing system and send it to the control system through the communication system. The implementation method where the user selects a suitable nursing parameter value from multiple nursing parameter values ​​corresponding to at least one nursing system can refer to the implementation method where the user selects at least one target nursing system in the above process, and will not be repeated here.

[0051] Upon receiving the parameter setting instruction, the control system can control at least one nursing system to operate according to its corresponding second nursing parameter value. Taking a beauty device as an example, at least one nursing system can be a vibration nursing system. The multiple nursing parameter values ​​corresponding to this vibration nursing system can include: vibration frequency level one, vibration frequency level two, and vibration frequency level three. If the user selects vibration frequency level two as the nursing parameter value, the control terminal can determine a parameter setting instruction that includes vibration frequency level two for the vibration nursing system based on the user's parameter setting operation. The control system can then control the vibration nursing system to operate at the level two vibration frequency according to this parameter setting instruction.

[0052] As another possible implementation, the corresponding instructions acquired by the control system can also be generated based on the user's corresponding operation sensed by the interactive system, such as the detection start instruction, first selection instruction, second selection instruction, parameter setting instruction, etc. mentioned above.

[0053] For example, the first selection instruction can be specifically determined by the interactive system based on a user selection operation for at least one nursing system. Specifically, the implementation methods of the aforementioned detection start instruction, first selection instruction, second selection instruction, and parameter setting instruction can refer to the corresponding implementation methods in the control terminal, and will not be elaborated here.

[0054] In practical applications, in response to user operations sensed by the interactive system, the control system controls at least one detection system to operate and detect the object of care. Afterward, it can control at least one nursing system to operate and provide care to the object, or it can continue to control at least one detection system to re-detect. Therefore, in some embodiments, the control system is also used to output a second prompt message after the detection by at least one detection system has completed. This second prompt message can prompt the user to instruct on subsequent operations of the nursing equipment. This second prompt message can be output through the interactive system or sent to the control terminal for output.

[0055] Optionally, if a retest command triggered by a user is received, at least one detection system is restarted to re-examine the patient. This retest command can be generated by the interactive system sensing the user's selection to retest. Specifically, the second prompt message could be, for example, whether to perform a retest. The interactive system could sense the user touching the "OK" button on the control panel, and the control system, based on the user-triggered retest command, could restart at least one detection system. Alternatively, the retest command can also be generated and sent by the control terminal sensing the user's retest operation.

[0056] As one implementation, if the control system does not receive a user-triggered retest command within the first time after outputting the second prompt message, it controls at least one nursing system to operate based on at least one status parameter value obtained by at least one detection system. This first time can be set according to the actual scenario, such as five seconds. It is understood that if no user-triggered retest command is received within the first time, it can be assumed that the user does not require retesting and nursing care can proceed directly; therefore, the control system can control at least one nursing system to operate.

[0057] As another implementation, if the control system receives a user-triggered operation command after outputting the second prompt message, it controls at least one nursing system to operate based on at least one status parameter value obtained by at least one detection system. Specifically, the operation command can be determined by the interactive system sensing the user's refusal to retest. The second prompt message indicates whether to retest; the interactive system can sense the user touching the refusal button on the control panel. In this case, the control system, based on the user-triggered operation command, will not control at least one detection system to retest, but instead will control at least one nursing system to operate based on at least one status parameter value obtained by at least one detection system.

[0058] Of course, the operating instruction can also be determined by the interactive system sensing the user's selected operation. Specifically, in response to the user's refusal to retest detected by the interactive system, the control system can send a third prompt message to the interactive system. This third prompt message can indicate whether or not to perform care. The interactive system can then sense the user's touch of the selection button on the control panel, thereby determining the operating instruction.

[0059] like Figure 2 As shown, the nursing system may also include a power supply system 107. The interaction system 106 senses and receives a user's power-on operation, establishing a power connection between the power supply system 107 and the control system 101 to trigger the control system 101 to start. Optionally, the control system may also be used to: detect the power supply of the power supply system and output a power level indicator based on the power supply level. Furthermore, as... Figure 2As shown, the care system may also include a charging system 108 connected to the power supply system 107. This charging system is used to connect to an external power source via a wired connection and charge the power supply system 107.

[0060] In some embodiments, before the control system detects the patient using at least one detection system, it can output a network configuration prompt. In response to a user's network configuration operation sensed by the interactive system, it establishes a connection with the network. The network configuration prompt can be, for example, a request for network connection. The user's network configuration operation sensed by the interactive system could be a user touching an "OK" button on a control panel. In response to this operation, the control system can establish a network connection, such as via Bluetooth. Alternatively, the interactive system can also sense a user pressing a "Decline" button on the control panel. In this case, the control system will not perform a network configuration operation and will proceed directly to subsequent operations, such as controlling at least one detection system to detect the patient.

[0061] In some embodiments, the control system is also used to detect faults in at least one detection system and at least one nursing system, and output fault prompt information. Specifically, the control system may output fault prompt information in the form of voice broadcast or indicator lights. For example, when the above systems are detected to be operating normally, the indicator light is green; when an abnormality is detected, the indicator light for the faulty system may be red. Of course, the above fault detection is not limited to at least one detection system and at least one nursing system; it can also detect faults in the power supply system and distribution network function. If a fault is found, corresponding fault prompt information can also be output, which can be set according to actual needs.

[0062] In practical applications, the nursing equipment may also include a device body to house all or part of the aforementioned control system, at least one nursing system, at least one detection system, power supply system, charging system, and interactive system.

[0063] As another embodiment, the nursing device may further include an electrode assembly. This electrode assembly may include multiple electrodes with a first end disposed within the device body and a second end extending beyond the device body to contact the patient. The at least one nursing system may include at least one electrode-type nursing system connected to one or more electrodes respectively. This electrode-type nursing system can be used to provide care by acting on the patient through one or more electrodes. The electrode is a metal component, and the electrode-type nursing system may, for example, be a microcurrent nursing system, which uses any two electrodes to release a microcurrent, or a radiofrequency nursing system, which uses one or more electrodes to output radiofrequency oscillation waves, etc. The electrode layout in the electrode assembly affects the nursing effect. To further improve the nursing effect, in some embodiments, the electrode assembly may include at least one set of electrode pairs and a third electrode. Each set of electrode pairs may include a first electrode and a second electrode. The first and second electrodes in each set of electrode pairs, as well as the first end of the third electrode, are disposed within the device body of the nursing device, and the second end extends beyond the device body to contact the patient. Specifically, the first and second electrodes in a set of electrode pairs may be distributed on both sides of the third electrode, and their extension heights may differ from those of the third electrode.

[0064] The device body can be composed of a first body and a second body. Taking a beauty device as an example, the second body can be the head structure of the beauty device, and the first body is the body of the beauty device. The electrode assembly can be specifically set on the second body, which can have an operating surface. The first end of the electrode assembly is set inside the device body of the care device, while the second end can extend out of the operating surface to contact the care object and perform care on the care object when the corresponding care system is running.

[0065] For ease of understanding, Figure 3a A cross-sectional view of the electrode assembly in a practical application is shown. Figure 3c A schematic diagram of one possible distribution of the electrode assembly is shown. Figure 3a as well as Figure 3c In the middle, the electrode assembly includes a set of electrode pairs, combined with Figure 3a as well as Figure 3c It is understood that the electrode assembly may include a first electrode 10, a second electrode 20, and a third electrode 30. The first electrode 10 and the second electrode 20 may be distributed on both sides of the third electrode 30. Assume the extension height of the first electrode 10 is H1, the extension height of the second electrode 20 is H2, and the extension height of the third electrode 30 is H3. H1 and H2 may differ from H3. Alternatively, the extension heights of both the first electrode 10 and the second electrode 20 may be greater than the extension height of the third electrode 30, such as... Figure 3aAs shown, H1 and H2 can both be greater than H3 to ensure that the first electrode, the second electrode, and the third electrode can all fit the patient and ensure the nursing effect.

[0066] As an alternative approach, to better conform to the skin of the patient, especially when the patient is on the face, the first, second, and third electrodes can be formed into an arc shape that curves towards the outer electrode (the first or second electrode), for example, as... Figure 3b The expression H1≥H3≥H2 can be shown, or it could be H2≥H3≥H1.

[0067] Furthermore, when the electrode assembly includes multiple electrode pairs, the extension height of the first and second electrodes in each electrode pair is greater than the extension height of the third electrode; wherein, multiple first electrodes are distributed on the same side of the third electrode, and their extension height gradually increases in order of distance from the third electrode; multiple second electrodes are distributed on the same side of the third electrode, and their extension height gradually increases in order of distance from the third electrode, so as to better conform to the patient being cared for. Figure 3d As shown, the electrode filled with black in the middle can represent the third electrode. The multiple electrodes to the left of the third electrode can be, for example, the first electrode. In this case, the multiple electrodes to the right of the third electrode can be the second electrode. Figure 3d It can be seen that multiple first electrodes can extend in increasing height from near to far of the third electrode, and multiple second electrodes can extend in increasing height from near to far of the third electrode. That is, the electrode assembly forms a groove shape to better fit the patient, ensuring that each electrode can fully contact the patient, thereby further guaranteeing the nursing effect.

[0068] Optionally, the distance between the first and second electrodes and the third electrode in each electrode pair can be equal. For example... Figure 3c As shown, the distances between the first electrode 10 and the second electrode 20 and the third electrode 30 are equal. Optionally, the first and second electrodes in each electrode pair can be aligned linearly with the third electrode on the same straight line. Figure 3cAs shown, the first electrode 10, the second electrode 20, and the third electrode 30 are located on the same straight line. The contact areas between the first and second electrodes and the patient in each electrode pair are different from the contact area between the third electrode and the patient, but can all be greater than or equal to the contact area between the third electrode and the patient. The contact areas of the first and second electrodes and the patient can be the same or different. For example, when the first, second, and third electrodes form an arc shape curving towards the outer electrode, the contact area corresponding to the first electrode can be greater than or equal to the contact area corresponding to the third electrode, and the contact area corresponding to the third electrode can be greater than or equal to the contact area corresponding to the second electrode; or, the contact area corresponding to the second electrode can be greater than or equal to the contact area corresponding to the third electrode, and the contact area corresponding to the third electrode can be greater than or equal to the contact area corresponding to the first electrode. Specifically, the contact area between the electrode and the patient refers to the end face area of ​​its second end. The end face of the electrode in the electrode assembly that contacts the patient, i.e., the second end face, can be an arc surface or a plane. In practical applications, to ensure better and fuller contact with the patient, the contact end face can be a plane.

[0069] As an optional implementation, the shapes of the end faces of the first and second electrodes in each electrode pair that contact the patient can be symmetrical about the axis of the third electrode. For example... Figure 3d As shown, the black-filled electrode in the middle position can represent the third electrode, the multiple electrodes to the left of the third electrode are the first electrodes, and the multiple electrodes to the right of the third electrode can be the second electrodes. It can be seen that the end face shapes of the first and second electrodes in each electrode pair that contact the patient can be symmetrical about the third electrode axis.

[0070] As an alternative implementation, the shapes of the end faces of the first and second electrodes in each electrode pair that contact the patient can be asymmetrical about the axis of the third electrode. For example... Figure 3e As shown, the black-filled electrode in the middle represents the third electrode, the multiple electrodes to the left of the third electrode are the first electrodes, and the multiple electrodes to the right of the third electrode are the second electrodes. It can be seen that the shapes of the end faces of the first and second electrodes that contact the patient can be asymmetrical about the axis of the third electrode.

[0071] In a practical application, the electrode assembly may include a set of electrode pairs, and at least one detection system in the nursing device may include an elasticity detection system. In this embodiment, the elasticity detection system shares electrodes with the electrode-based nursing system, enabling elasticity detection of the patient. At least one of the first and second electrodes, and the third electrode, can be pressed by the patient and move along the direction of pressure to establish a connection with the elasticity detection system. The elasticity detection system can detect pressure parameter values ​​generated by pressure applied to at least one of the first and second electrodes, and the third electrode. These pressure parameter values ​​can be voltage or pressure values, representing the pressure applied to the electrodes. Based on the detection results of the elasticity detection system, the control system can determine the first pressure parameter value applied to the third electrode when the pressure parameter values ​​applied to the first and / or second electrodes meet the pressure balance condition, and calculate the patient's elasticity value based on the first pressure parameter value.

[0072] Optionally, the elastic detection system can utilize a pressure detection component to detect the pressure parameter value applied to the electrode. This pressure detection component may include an elastic structure and a strain detection circuit connected to the elastic structure. The first end of the elastic structure in the pressure detection component can be fixed within the device body, while the second end is suspended and connected to the first end of the corresponding electrode. In practical applications, this elastic structure can be implemented as an elastic sheet or a spring, etc. During pressure detection, the elastic structure can undergo elastic deformation due to the movement of the corresponding electrode. At this time, the strain detection circuit can generate a corresponding pressure parameter value based on the resistance change caused by the elastic deformation of the elastic structure. The specific implementation method of the strain detection circuit generating the corresponding pressure parameter value based on the resistance change caused by the elastic deformation of the elastic structure will be described in detail below.

[0073] In some embodiments, the elasticity detection system detects the pressure parameter value applied to the electrode, and this can be implemented in various ways. As one optional implementation, the elasticity detection system may include a first pressure detection component and a second pressure detection component. The first pressure detection component can be connected to either the first or second electrode to detect the pressure parameter value generated by the pressure applied to the first or second electrode; the second pressure detection component can be connected to a third electrode to detect the pressure parameter value generated by the pressure applied to the third electrode.

[0074] As an alternative implementation, the elasticity detection system may include two first pressure detection components and a second pressure detection component. The two first pressure detection components may be connected to a first electrode and a second electrode, respectively, to detect the pressure parameter values ​​generated by the pressure applied to the first and second electrodes. The second pressure detection component may be connected to a third electrode to detect the pressure parameter value generated by the pressure applied to the third electrode.

[0075] Taking a nursing device comprising a set of electrode pairs, including a first electrode and a second electrode, as an example, the elasticity detection system can detect the pressure parameter values ​​generated by the pressure applied to the first electrode, the second electrode, and the third electrode, respectively. For ease of description, the pressure parameter value generated by the pressure applied to the first electrode can be represented by F1, the pressure parameter value generated by the pressure applied to the second electrode by F2, and the pressure parameter value generated by the pressure applied to the third electrode by F3. Specifically, the elasticity detection system can use two first pressure detection components and a second pressure detection component to detect each pressure parameter value. The method of using the pressure detection components to detect each pressure parameter value will be described in detail below.

[0076] Furthermore, to ensure sufficient contact between the nursing device and the patient during pressure detection, the control system can specifically detect if the pressure parameter value applied to the first electrode is within a first range and the pressure parameter value applied to the second electrode is within a second range, and then determine the first pressure parameter value applied to the third electrode. The first and second ranges can be the same or similar, thereby making F1 equal to F2, or making the ratio of F1 to F2 close to 1, i.e., the absolute value of the difference between the ratio and 1 is less than a preset threshold. This preset threshold could be, for example, 0.05, and the range of the ratio of F1 to F2 could be 0.95 to 1.05. The first value range can be A1~A2, and the second value range can be B1~B2. If the pressure parameter value F1 applied to the first electrode is A, the pressure parameter value F2 applied to the second electrode is B. A is within the first value range, and B is within the second value range. This indicates that the pressure applied to the first electrode and the second electrode is similar, and the nursing device is in full contact with the nursing object. At this time, the pressure parameter value F3 applied to the third electrode is determined, and F3 can be called the first pressure parameter value.

[0077] Based on the first pressure parameter value, the control system can calculate the elasticity of the object being cared for. The method for calculating elasticity based on the pressure parameter value can be flexibly set according to actual circumstances, and this application embodiment does not impose specific limitations on this.

[0078] In practical applications, to ensure that for different care recipients, the control system can detect when the pressure parameter value applied to the first electrode is within a first value range, and the pressure parameter value applied to the second electrode is also within a second value range, as an alternative implementation, the control system specifically detects when the pressure parameter value applied to the first electrode reaches a first threshold, and when the pressure parameter value applied to the second electrode reaches a second threshold, and reads the first pressure parameter value applied to the third electrode when the pressure parameter value applied to the first electrode is within the first value range and the pressure parameter value applied to the second electrode is within the second value range. Here, the first threshold can be represented by C, and the second threshold can be represented by D. C and D can be equal, or the ratio of C to D can be close to 1, that is, the absolute value of the difference between the ratio and 1 is less than a preset threshold. This preset threshold can also be 0.05, meaning the ratio of C to D can range from 0.95 to 1.05. The value of C can be greater than A2 in the first value range, and D can be greater than B2 in the second value range. Based on this, the control system can detect the processes of F1=C and F2=D, and read the value of F3 when F1 is within the range of A1~A2 and F2 is within the range of B1~B2. Based on this first pressure parameter value, the control system can calculate the elasticity of the object being cared for. The method for calculating elasticity based on the pressure parameter value can be flexibly set according to actual conditions, and this application embodiment does not specifically limit this.

[0079] The elastic structures in the first and second pressure detection components described in one or more embodiments above can be arranged in different ways. As an optional implementation, such as... Figure 4a As shown, the elastic structures in the first and second pressure detection components can be stacked and located on different planes. As another optional implementation, such as... Figure 4b As shown, the elastic structures in the first pressure detection component and the second pressure detection component can be linearly arranged on the same plane.

[0080] As another optional implementation, the elasticity detection system may include a fourth pressure detection component. The fourth pressure detection component may be connected to at least one of the third electrode, the first electrode, and the second electrode. In one implementation, the fourth pressure detection component may be connected to the third electrode, the first electrode, and the second electrode. Figure 4cAs shown, the fourth pressure detection component may include an "E"-shaped elastic structure and three strain detection circuits. The elastic structure includes a support fixed within the device body and three elastic arms, each with its first end integrally connected to the support and its second end suspended. A first electrode, a second electrode, and a third electrode can each be connected to the second end of an elastic arm. Each elastic arm is connected to a strain detection circuit. During elastic detection, the elastic arm can be moved by the corresponding electrode to generate elastic deformation. The strain detection circuit generates a corresponding pressure parameter value based on the resistance change caused by the elastic deformation of the corresponding elastic arm.

[0081] In another implementation, the fourth pressure sensing component can be connected to either the third electrode, or either the first electrode or the second electrode. For example... Figure 4d As shown, the fourth pressure detection component may include an elastic structure with a "U" shape and two strain detection circuits. The elastic structure includes a support fixed within the device body and two elastic arms with their first end integrally connected to the support and their second end suspended. Either the first electrode, the second electrode, and the third electrode are each connected to an elastic arm. Each elastic arm is connected to a strain detection circuit. The elastic arm can be driven to undergo elastic deformation based on the movement of the corresponding electrode. The strain detection circuit can generate a corresponding pressure parameter value based on the resistance change caused by the elastic deformation of the elastic structure.

[0082] The strain detection circuit described in one or more embodiments above may include a Wheatstone bridge circuit. In this Wheatstone bridge circuit, at least one bridge arm element can be configured as a strain gauge connected to an elastic structure. When one bridge arm element of the Wheatstone bridge circuit is configured as a strain gauge connected to the elastic structure, the other three bridge arm elements can be configured as resistors, and the Wheatstone bridge circuit can be a single-bridge circuit. When two bridge arm elements of the Wheatstone bridge circuit are configured as strain gauges connected to the elastic structure, the other two bridge arm elements can be configured as resistors, and the Wheatstone bridge circuit can be a half-bridge circuit. When four bridge arm elements of the Wheatstone bridge circuit are configured as strain gauges connected to the elastic structure, the Wheatstone bridge circuit can be a full-bridge circuit. The number of strain gauges in the Wheatstone bridge circuit can be set according to actual needs and is not specifically limited here. When no pressure detection is performed, the Wheatstone bridge circuit is in a balanced state, and the output voltage value is 0; when pressure detection is performed, the elastic structure is subjected to stress, and the strain gauges will undergo slight deformation, at which time the resistance value of the strain gauges changes. In other words, due to the elastic deformation of the elastic structure causing a change in resistance, the Wheatstone bridge circuit becomes unbalanced, and the output voltage is U. This voltage value reflects the resistance change of the strain gauge, and thus the corresponding pressure parameter value can be determined. Optionally, such as Figure 5As shown, the strain detection circuit may further include an analog-to-digital converter circuit connected to a Wheatstone bridge circuit. This analog-to-digital converter circuit may include a control chip U5, a transistor Q6, resistors R1 (21st), R2 (22nd), R3 (23rd), R4 (24th), R46 (25th), R48 (26th), R50 (27th), R51 (28th), capacitors C27 (17th), C31 (18th), C34 (19th), C38 (20th), C39 (21st), and C44 (22nd). Resistors R1 (21st), R2 (22nd), R3 (23rd), and R4 (24th) constitute the Wheatstone bridge circuit. The first terminal of resistor R1 (21st) is connected to the first terminal of resistor R4 (24th) and pin 3 of control chip U5; its second terminal is connected to the first terminal of resistor R2 (22nd); the second terminal of resistor R2 (22nd) is grounded. The first terminal of resistor R3 (23rd) is connected to the second terminal of resistor R4 (24th), and its second terminal is grounded. The first terminal of resistor R46 (25th) is connected to the first terminal of resistor R2 (22nd), and its second terminal is connected to pin 8 of control chip U5. The first terminal of resistor R48 (26th) is connected to the first terminal of resistor R3 (23rd), and its second terminal is connected to pin 7 of control chip U5. The first terminal of resistor R50 (27th) is connected to pin 3 of control chip U5, and its second terminal is connected to pin 4 of control chip U5. The first terminal of resistor R51 (28th) is grounded, and its second terminal is connected to pin 5 of control chip U5. The circuit is connected to pin 4 of the control chip U5; capacitors C27 (seventeenth) and C31 (eighteenth) are connected in parallel, with the first terminal of C27 connected to pin 1 of the control chip U5 and the second terminal grounded; capacitor C34 (nineteenth) has its first terminal connected to pin 3 of the control chip U5 and its second terminal grounded; capacitor C38 (twentieth) has its first terminal grounded and its second terminal connected to pin 6 of the control chip U5; capacitor C39 (twentieth) has its first terminal connected to pin 7 of the control chip U5 and its second terminal connected to pin 8 of the control chip U5; capacitor C44 (twentieth) has its first terminal connected to pin 16 of the control chip U5 and its second terminal connected to pin 15 of the control chip U5; the base of transistor Q6 is connected to pin 2 of the control chip U5, its emitter is connected to pin 1 of the control chip U5, and its collector is connected to pin 3 of the control chip U5. The analog-to-digital converter circuit is connected to the control system. The analog-to-digital converter circuit can amplify and convert the output voltage U in the Wheatstone bridge circuit, and then output the result to the control system, which will then determine the final pressure parameter value.

[0083] In some embodiments, the control system can also be used to output corresponding pressure prompts based on different pressure parameter values ​​corresponding to the first electrode and / or the second electrode. The control system can output the pressure prompts via an interactive system in the form of voice broadcasts, such as outputting different types of sounds or sounds of different decibel levels based on different pressure parameter values.

[0084] In another practical application, the nursing device may specifically include multiple electrode pairs, each electrode pair forming an electrode set with a third electrode to create at least one electrode set. At least one detection system in the nursing device may include an elasticity detection system. In each electrode pair, at least one electrode and the third electrode can be pressed by the patient and moved along the direction of pressure to establish a connection with the elasticity detection system. The elasticity detection system can detect pressure parameter values ​​generated by the pressure applied to at least one electrode and the third electrode in each electrode pair. These pressure parameter values ​​can be voltage or pressure values, representing the pressure applied to the electrodes.

[0085] The control system can, based on the detection results of the elasticity detection system, read the second pressure parameter value applied to the third electrode for each electrode set when the pressure parameter value applied to the electrode pair meets the pressure balance condition, and calculate the candidate elasticity value of the patient based on the second pressure parameter value. Furthermore, it can calculate the patient's elasticity value based on at least one candidate elasticity value corresponding to at least one electrode set. Specifically, the patient's elasticity value can be obtained by weighted averaging or average calculation of the at least one candidate elasticity value. The method for reading the second pressure parameter value applied to the third electrode for each electrode set can refer to the method for determining the first pressure parameter value described above, and will not be repeated here.

[0086] Alternatively, the elasticity detection system can use a pressure detection component to detect the pressure parameter value applied to the electrode, and there are various ways to implement this.

[0087] As an optional implementation, the elasticity detection system may include at least one set of first pressure detection components and a second pressure detection component. The first pressure detection component may include a single first pressure detection component that can be connected to either the first or second electrode in a set of electrode pairs to detect the pressure parameter value generated by the pressure applied to the first or second electrode in the set of electrode pairs. The second pressure detection component may be connected to a third electrode to detect the pressure parameter value generated by the pressure applied to the third electrode.

[0088] As an alternative implementation, the elasticity detection system may include at least one set of first pressure detection components and a second pressure detection component. The set of first pressure detection components may include two first pressure detection components, each connected to a first electrode and a second electrode in a set of electrode pairs, respectively, to detect the pressure parameter values ​​generated by the pressure applied to the first and second electrodes. The second pressure detection component may be connected to a third electrode to detect the pressure parameter values ​​generated by the pressure applied to the third electrode.

[0089] As an alternative implementation, the elasticity detection system may include a fourth pressure detection component. This fourth pressure detection component may be connected to a third electrode, and to at least one of the first and second electrodes in at least one set of electrode pairs.

[0090] Furthermore, as another embodiment, at least one detection system in the nursing device may include an elasticity detection system. The nursing device may also include: a first contact, a second contact, and a third contact, with a first end disposed within the device body and a second end extending beyond the device body to contact the object being cared for. Optionally, at least two of the first, second, and third contactes may be made of metal and connected to at least one electrode-type nursing system, i.e., they can be implemented as electrodes in an electrode assembly. In practical applications, the metal material is preferably stainless steel. At least one of the first and second contactes and the third contact can be pressed by the object being cared for and move along the pressure direction to establish a connection with the elasticity detection system. The elasticity detection system can detect the pressure parameter value generated by the pressure applied to at least one of the first and second contactes and the third contact. This pressure parameter value can be a voltage value or a pressure value. Based on the detection results of the elasticity detection system, when the pressure parameter value applied to the first and / or second contact meets the pressure balance condition, the control system can read the third pressure parameter value applied to the third contact and calculate the elasticity value of the object being cared for based on the third pressure parameter value.

[0091] As an optional implementation, the elasticity detection system may include a first pressure detection component and a second pressure detection component. The first pressure detection component may be connected to either a first contact or a second contact to detect the pressure parameter value generated by the pressure applied to the first or second contact; the second pressure detection component may be connected to a third contact to detect the pressure parameter value generated by the pressure applied to the third contact.

[0092] As an alternative implementation, the elasticity detection system may include two first pressure detection components and a second pressure detection component. The two first pressure detection components may be connected to a first contact and a second contact, respectively, to detect the pressure parameter values ​​generated by the pressure applied to the first and second contact components. The second pressure detection component may be connected to a third contact to detect the pressure parameter values ​​generated by the pressure applied to the third contact component.

[0093] As another optional implementation, the elasticity detection system may include a fourth pressure detection component. The fourth pressure detection component may be connected to at least one of the third contact and the first and second contacts.

[0094] In one implementation, the fourth pressure detection component can be connected to the third contact, the first contact, and the second contact, respectively. The fourth pressure detection component may include an "E"-shaped elastic structure and three strain detection circuits. The elastic structure includes a support fixed within the device body and three elastic arms, each with its first end integrally connected to the support and its second end suspended. The first, second, and third contactes can each be connected to the second end of an elastic arm, and each elastic arm is connected to a strain detection circuit. During elastic detection, the elastic arm can be moved by the corresponding contact to generate elastic deformation. The strain detection circuit generates a corresponding pressure parameter value based on the resistance change caused by the elastic deformation of the corresponding elastic arm.

[0095] In another implementation, the fourth pressure detection component can be connected to either the third contact, the first contact, or the second contact. The fourth pressure detection component may include a U-shaped elastic structure and two strain detection circuits. The elastic structure includes a support fixed within the device body and two elastic arms with their first end integrally connected to the support and their second end suspended. Either the first or second contact, and the third contact, are each connected to an elastic arm, and each elastic arm is connected to a strain detection circuit. The elastic arm can be moved by the corresponding contact to generate elastic deformation, and the strain detection circuit can generate a corresponding pressure parameter value based on the resistance change caused by the elastic deformation of the elastic structure.

[0096] As another embodiment, at least one detection system in the nursing device may include a moisture detection system. The control system can use the moisture detection system to detect the subject being cared for and obtain the subject's moisture parameter value. Optionally, the nursing device may also include a pressure detection system to detect the pressure parameter value generated by pressure applied to the electrode assembly. The electrode assembly can be pressed by the subject being cared for and moved along the direction of pressure to establish a connection with the pressure detection system. The implementation method for the pressure detection system to detect the pressure parameter value generated by pressure applied to the electrode assembly can refer to the specific implementation method of the elastic detection system detecting the pressure parameter value generated by pressure applied to the electrode assembly in the above embodiments, and will not be repeated here. When the nursing device includes an elastic detection system, the pressure detection system can be the elastic detection system in the above embodiments. Based on the detection results of the pressure detection system, the control system can use the moisture detection system to detect the subject being cared for and obtain the subject's moisture parameter value when the pressure parameter value on the electrode assembly meets the pressure setting conditions. The pressure setting conditions can be set according to actual needs.

[0097] Since electrode assemblies can be implemented in various ways, as one optional implementation, the electrode assembly can include a first electrode and a second electrode from a set of electrode pairs. The first and second electrodes can be pressed by the patient and moved along the direction of pressure to establish a connection with the pressure detection system.

[0098] At this time, the pressure detection system can detect the pressure parameter values ​​generated by the pressure applied to the first electrode and the second electrode respectively. The implementation method for detecting the pressure parameter values ​​using the pressure detection system can refer to the implementation method in the previous embodiments, and will not be repeated here. When performing moisture detection, the moisture parameter value is affected by the pressure parameter value on the electrodes. Therefore, the control system can use the moisture detection system to detect the nursing object and obtain the moisture parameter value of the nursing object when the pressure parameter values ​​on both the first electrode and the second electrode are greater than a first parameter threshold. This indicates that the nursing device is in sufficient contact with the nursing object. Furthermore, the control system can stop using the moisture detection system to detect the nursing object when the pressure parameter values ​​on both the first electrode and the second electrode are greater than a first set threshold, and output a prompt message to remind the user to stop applying pressure. The first set threshold can be greater than the first parameter threshold.

[0099] As an alternative implementation, the electrode assembly may include a first electrode, a second electrode, and a third electrode in a set of electrode pairs. The first and second electrodes may be distributed on both sides of the third electrode and may be located on the same straight line. The third electrode can be pressed by the patient and moved along the direction of pressure to establish a connection with a pressure detection system. In this case, the pressure detection system can detect the pressure parameter value generated by the pressure applied to the third electrode.

[0100] The control system can detect the moisture content of the patient using a moisture detection system when the pressure parameter value on the third electrode exceeds the second parameter threshold. This indicates that the nursing device is in contact with the patient, allowing moisture detection to be performed and the patient's moisture value calculated based on the third pressure parameter value. Alternatively, the control system can also stop detecting the patient using the moisture detection system when the pressure parameter value on the third electrode exceeds a second set threshold. This second set threshold can be higher than the second parameter threshold.

[0101] In practical applications, to ensure proper moisture detection, the control system can output a retest prompt when the pressure on the electrode assembly meets the retest condition. Specifically, a retest condition can be set as the pressure parameter value on the third electrode being less than the second parameter threshold. This indicates that the nursing device is not in sufficient contact with the patient, and in this case, accurate moisture parameter values ​​cannot be obtained. Therefore, a retest prompt can be output to remind the user to adjust the nursing device to reapply pressure. The control system can output the retest prompt in the form of a voice announcement, for example.

[0102] In some implementations, the first, second, and third electrodes can be set with protection thresholds. When a user uses at least one nursing system to perform nursing care, if the pressure parameter values ​​detected by the first, second, and third electrodes reach the threshold, a prompt message will be output. This prompt may be in the form of voice, graphic display, or LED display, to alert and inform the user that the nursing care or pressure is too strong and that the nursing pressure should be reduced to avoid damaging the skin due to excessive pressure during nursing care.

[0103] As described above, at least one electrode-based nursing system in this nursing device may include a microcurrent nursing system for applying a microcurrent to the patient using electrode components. The control system, based on at least one state parameter value, controls the operation of at least one nursing system, which may include controlling the voltage applied to the electrode components by the microcurrent nursing system based on a moisture parameter value. Specifically, the control system can control the voltage applied to the electrode components by the microcurrent nursing system in various ways. As an optional implementation, the control system may determine a corresponding target voltage based on the moisture parameter value and control the microcurrent nursing system to apply the target voltage to the electrode components. The correspondence between different moisture parameter values ​​and voltages can be preset according to actual needs and is not specifically limited here.

[0104] As an alternative implementation, the moisture detection system is specifically used to detect the current applied to the object by the electrode assembly, obtaining a corresponding voltage detection value. This moisture parameter value can specifically be the voltage detection value. The control system, based on the moisture parameter value, controls the voltage applied to the electrode assembly by the microcurrent nursing system, which may include: comparing the voltage detection value with a reference voltage value; and adjusting the voltage applied to the electrode assembly by the microcurrent nursing system based on the comparison result until the voltage detection value and the reference voltage value meet a stable condition. The reference voltage value can be pre-configured by the system or set by the user. Therefore, in some embodiments, the control system can also determine the reference voltage value based on a user-triggered parameter setting command, and control the microcurrent nursing system to apply voltage to the electrode assembly based on the reference voltage value. This parameter setting command can be determined by the control terminal based on a user-triggered parameter setting operation, or it can be determined by the interactive system based on a user-triggered parameter setting operation.

[0105] In practical applications, the control system can provide multiple parameter setting levels. Based on the parameter setting command triggered by the user's level selection operation, the reference voltage value corresponding to the selected level is determined. These multiple parameter setting levels can be physical buttons provided by the interactive system, specifically deployed on the device's casing for user operation, or they can be virtual buttons displayed on the interactive system's control panel for user operation. Furthermore, the control system can provide these multiple parameter setting levels to the control terminal for display on the terminal's display interface.

[0106] To achieve voltage regulation so that the detected voltage value and the reference voltage value meet the stability condition, as another embodiment, such as... Figure 6The diagram shown is a structural schematic of an embodiment of a microcurrent nursing system provided in this application. The microcurrent nursing system may include a boost control module 601, a voltage feedback module 602, and a voltage output module 603 connected to a control system. The voltage output module 603 is connected to the electrode assembly and the boost control module 601, and can be used to acquire the output voltage of the boost control module and apply it to the electrode assembly. The voltage feedback module 602 is connected to the boost control module 601 and is used to acquire the voltage detection value obtained by the moisture detection system and the control voltage of the boost control module 601; and obtain a feedback voltage based on the comparison result of the voltage detection value and the reference voltage value, the control voltage, and the voltage adjustment value determined by the control system based on the voltage detection value. The boost control module 601 can boost the power supply voltage based on the feedback voltage to obtain the output voltage. The control system can adjust the voltage adjustment value and current adjustment value output to the voltage feedback module based on the voltage detection result. In other implementations, the smart terminal is wirelessly connected to the nursing equipment. The smart terminal is equipped with an application (APP) adapted to the nursing equipment. The APP has corresponding nursing modes and parameters, and the nursing mode and parameters are determined based on parameter setting commands triggered by user operations or voice commands. In the APP, setting the nursing mode and parameters can take any of the following forms: point selection, stepless adjustment, fixed value, graphic input, voice input, etc., without specific limitations. Specifically, the user inputs voice commands through the APP to steplessly adjust the voltage and current adjustment values ​​output to the voltage feedback module. The control system receives these nursing parameters and adjusts the microcurrent intensity of the microcurrent nursing system. In other nursing modes or parameters, the user can also perform stepless adjustments in the APP, including but not limited to: adjusting vibration frequency, adjusting nursing time, adjusting working current or voltage, adjusting nursing pressure, etc.

[0107] During microcurrent care, the control system controls the boost control module 601 to boost the power supply voltage to obtain an output voltage, which is then output to the voltage output module 603. The voltage output module 603 applies the output voltage to the electrode assembly for microcurrent care. Simultaneously, the boost control module 601 can also output a control voltage to the voltage feedback module 602 for voltage regulation. The control system controls the moisture detection system to detect the voltage applied to the electrode assembly and outputs the detected voltage to the voltage feedback module 602. The voltage feedback module 602 compares the detected voltage with a reference voltage to obtain a comparison result. Based on this comparison result and the control voltage, it determines a voltage adjustment value to obtain a feedback voltage, which is then output to the boost control module 601. The boost control module 601, based on this feedback voltage, boosts the power supply voltage to achieve voltage regulation, ensuring that the detected voltage and the reference voltage meet stable conditions.

[0108] Optionally, the boost control module may include a boost unit, a switch control unit connected to the boost unit, and an output unit connected to the switch control unit. The boost unit boosts the power supply voltage when the switch control unit is turned on. The switch control unit adjusts the duty cycle of the switch control unit's drive voltage based on the output unit voltage. When the output voltage increases, the switch control unit decreases the duty cycle of its drive voltage, thus decreasing the output voltage; when the output voltage decreases, the switch control unit increases the duty cycle of its drive voltage, thus increasing the output voltage. The output unit obtains the output voltage. Furthermore, the boost control module may include a filtering unit for filtering the voltage. In a practical application, the boost control module can be implemented as a boost circuit (a type of boost chopper circuit) to adjust the output voltage based on the feedback voltage. As an optional implementation, such as... Figure 7The diagram shows a schematic representation of an embodiment of a boost chopper circuit. This boost chopper circuit may include an inductor L1, a Schottky diode DZ6, a first MOSFET Q10, a boost circuit chip U3, an electrolytic capacitor EC2, a first capacitor C17, a second capacitor C20, a third capacitor C6, a fourth capacitor C18, a fifth capacitor C19, a first resistor R35, a second resistor R38, a third resistor R34, a fourth resistor R36, and a fifth resistor R37. Specifically, the inductor L1, Schottky diode DZ6, first MOSFET Q10, and second resistor R38 constitute a boost unit; the boost circuit chip U3 and first resistor R35 constitute a switch control unit; third resistor R34, fourth resistor R36, and fifth resistor R37 constitute an output unit; and electrolytic capacitor EC2, first capacitor C17, second capacitor C20, third capacitor C6, fourth capacitor C18, and fifth capacitor C19 constitute a filter unit.Specifically, the first terminal of inductor L1 is connected to the power supply system to receive the battery voltage AD-BAT-V output by the power supply system, and the second terminal is connected to the positive terminal of Schottky diode DZ6; the positive terminal of Schottky diode DZ6 is connected to the drain of the first MOSFET Q10, and the negative terminal is connected to the voltage output module to prevent the output voltage VOUT from short-circuiting to ground; the gate of the first MOSFET Q10 is connected to the boost circuit chip U3, the source is connected to the first terminal of the second resistor R38, and the drain is connected to the positive terminal of Schottky diode DZ6; the boost circuit chip U3 may include an enable interface EN, which enables... The EN port is connected to the control system through the first resistor R35 to receive the enable signal DT-EN output by the control system. The boost circuit chip U3 may also include a voltage input interface VIN, which can be connected to the power supply system. The VIN port can also be grounded through the second capacitor C20. The boost circuit chip U3 may also include a feedback voltage input interface FB, which can be connected to the voltage feedback module to receive the feedback voltage DT-FB output by the voltage feedback module. The boost circuit chip U3 may also include a ground interface GND for grounding. The boost circuit chip U3 may also include a drive pulse interface DRV, which can be connected to the gate of the first MOSFET for outputting a drive pulse signal. The boost circuit chip U3 may also include a current detection input terminal, which can be connected to R38 and the source of the first MOSFET to limit the current of the first inductor L1 to not exceed a current threshold. The electrolytic capacitor EC2 is connected in parallel with the first capacitor C17, with the first terminal of EC2 connected to the first inductor L1 and the second terminal grounded. The third capacitor C... 6. The fourth capacitor C18 and the fifth capacitor C19 are connected in parallel, and the first terminal of the third capacitor is connected to the negative terminal of the Schottky diode DZ6, while the second terminal is grounded; the third resistor R34, the fourth resistor R36, and the fifth resistor R37 are connected in series, and the first terminal of the third resistor R34 is connected to the negative terminal of the Schottky diode DZ6, while the second terminal is connected to the first terminal of the fourth resistor R36; the second terminal of the fourth resistor R36 is connected to the first terminal of the fifth resistor R37, and can also be connected to the voltage feedback module for outputting the control voltage DT-VB; the second terminal of the fifth resistor R37 is grounded.

[0109] Optionally, such as Figure 8As shown, the voltage feedback module may include a current amplifier circuit, a feedback amplifier circuit, and a voltage amplifier circuit. The negative input of the current amplifier circuit is connected to the control system to obtain the reference voltage value input by the control system; the positive input is connected to the moisture detection system to obtain the voltage detection value input by the moisture detection system; and the output is connected to the positive input of the voltage amplifier circuit. The positive input of the feedback amplifier circuit is connected to the boost control module to obtain the control voltage of the boost control module; and the output is connected to the negative input of the feedback amplifier circuit for following. In another embodiment, a resistor may be connected between the negative input and output of the feedback amplifier circuit to achieve negative feedback amplification. The negative input of the voltage amplifier circuit is connected to the control system to obtain the voltage adjustment value output by the control system; and the output is connected to the boost control module to provide the feedback voltage.

[0110] During microcurrent nursing, the control system can control the moisture detection system to detect and obtain a voltage detection value U1. This voltage detection value U1 is input to the positive input terminal of the current amplifier circuit, and the reference voltage value DAC-CI / O is input to the negative input terminal of the current amplifier circuit. The current amplifier circuit compares the voltage detection value U1 and the reference voltage value DAC-CI / O to obtain the comparison result and the output value U2 of the current amplifier circuit. The output value U2 of the current amplifier circuit is input to the positive input terminal of the voltage amplifier circuit. Simultaneously, the positive input terminal of the voltage amplifier circuit also receives the control voltage DT_VB from the boost control module 601. The negative input terminal of the voltage amplifier circuit receives the voltage adjustment value DAC-VI / O output by the control system. Based on the output value U2 of the current amplifier circuit, the control voltage DT_VB in the boost control module, and the voltage adjustment value DAC-VI / O, a feedback voltage DT_FB is determined. This feedback voltage DT_FB is input to the boost control module, which then boosts the power supply voltage based on the feedback voltage DT_FB to obtain the output voltage.

[0111] In the above process, when the voltage detection value U1 obtained by the moisture detection system is less than or equal to the reference voltage value DAC-CI / O, it indicates that the current value in the microcurrent care process is less than the reference value. At this time, the current amplification circuit compares the voltage detection value U1 with the reference voltage value DAC-CI / O. The output value U2 of the current amplification circuit is 0, and the positive input terminal of the voltage amplification circuit only has the control voltage DT_VB. At this time, the voltage adjustment value DAC-VI / O is increased, which reduces the feedback voltage DT_FB output by the voltage amplification circuit, thereby increasing the output voltage VOUT in the boost control module, thus increasing the current value in the microcurrent care process for adjustment. When the detected voltage U1 is greater than the reference voltage DAC-CI / O, it indicates that the current value during the microcurrent care process is greater than the reference value. At this time, the current amplification circuit compares the detected voltage U1 with the reference voltage DAC-CI / O. The output value U2 of the current amplification circuit is not 0. The positive input of the voltage amplification circuit is the output value U2 of the current amplification circuit and the control voltage DT_VB. At this time, the voltage adjustment value DAC-VI / O is decreased, which increases the feedback voltage DT_FB output by the voltage amplification circuit. This, in turn, decreases the output voltage VOUT in the boost control module, thereby reducing the current value during the microcurrent care process. Through the above adjustment process, the detected voltage U1 and the reference voltage DAC-CI / O are balanced, keeping the current during the microcurrent care process constant at the set value.

The second amplifier U1A is connected to a voltage, which can be 3.3V, and the tenth capacitor C3 is used for filtering. The eleventh capacitor C2 and the fifteenth resistor R3 are connected in parallel. The first terminal of the eleventh capacitor C2 is connected to the negative input terminal of the second amplifier U1A, and the second terminal is connected to the output terminal of the second amplifier U1A, for filtering. The first terminal of the fifteenth resistor R3 is connected to the negative input terminal of the second amplifier U1A, and the second terminal is connected to the output terminal of the second amplifier U1A, for limiting the amplification factor of the second amplifier U1A.

[0115] In some embodiments, the current amplification circuit can also acquire the voltage detection value through a current detection circuit. For example... Figure 10The diagram shows a schematic representation of an embodiment of a current detection circuit. This current detection circuit may include a third amplifier U2A, sixteenth resistor R22, seventeenth resistor R28, eighteenth resistor R27, nineteenth resistor R30, twentieth resistor R26, thirteenth capacitor C15, fourteenth capacitor C14, fifteenth capacitor C12, sixteenth capacitor C13, and a Zener diode DZ5.

[0116] Optionally, such as Figure 11 The diagram illustrates a structural schematic of one embodiment of a voltage output module. This voltage output module may include an H-bridge circuit composed of four field-effect transistors. The output terminal of the H-bridge circuit is connected to an electrode assembly, the input terminal is connected to a boost control module to obtain the output voltage, and the control terminal is connected to a control system. The control system is also used to adjust the driving frequency of the H-bridge circuit so that the H-bridge circuit outputs pulse signals of different frequencies. Optionally, the voltage output module may also include a sampling resistor Rd connected in series with the H-bridge circuit. The moisture detection system detects the current applied to the object by the electrode assembly to obtain the corresponding voltage detection value, specifically the voltage detection value corresponding to the sampling resistor.

[0117] In some embodiments, the control system can also calculate the moisture level of the patient based on the voltage detection value. Specifically, the current acting on the patient can be calculated based on the voltage detection value and the sampling resistor. Based on this current value and the output voltage in the voltage output module, the resistance value in the voltage output module can be calculated. This resistance value is the sum of the patient's impedance and the sampling resistor, thus allowing the calculation of the patient's impedance. Therefore, the moisture level of the patient can be obtained.

[0118] As described above, the nursing equipment includes a main body that can house various components, such as control systems, nursing systems, and detection systems. The main body may include a housing that forms a cavity to accommodate the various components.

[0119] In one possible implementation, the device body may include a first body and a second body. For ease of understanding, as... Figures 12a-12g This shows multiple views of a nursing device in a practical application (where, Figure 12a Main view. Figure 12b This is the rear view. Figure 12c Right view Figure 12d Left view Figure 12e It is a 3D image. Figure 12f This is a top view. Figure 12g (This is a bottom view). It should be noted that... Figures 12a-12g This application is merely an example to illustrate the structural shape of nursing equipment and is not limited thereto. Figures 12a-12g As shown in at least part of the illustrations, the main body of the nursing device may include a first body 1201 and a second body 1202. The first body 1201 can be the main body of the nursing device, and the second body 1202 can be the head structure for providing care to the recipient. The following mainly focuses on... Figure 12a The main view shown illustrates that the second body 1202 may be equipped with an operating surface 1203 that contacts the object being cared for. The user uses the care device to bring the operating surface 1203 into contact with the object, such as the skin, to achieve skin care. This operating surface 1203 may be approximately elliptical in shape to better conform to the object being cared for. Due to different user techniques and pressure, the operating surface and the object may require multiple adjustments to achieve a proper fit.

[0120] To achieve a better fit to the face, in the embodiments of this application, see [reference needed]. Figure 13a The sectional view of the nursing equipment shown is as follows. Figure 13b as well as Figure 13c Exploded views of the nursing equipment shown from different angles, and Figure 13d Partial disassembly diagram of the nursing equipment is shown. Figure 13e and Figure 13f As shown in the cross-sectional views of the second body, the nursing device may further include a rotating assembly 1204 fixed within the first body 1201. The second body 1202 may include an extended end 1205 sleeved within the rotating assembly 1204. The second body 1202 is rotatable relative to the first body 1201 via the rotating assembly 1204; optionally, the second body 1202 can rotate relative to the first body 1201 within a preset angle range. Figure 12a As shown, the second body 1202 can rotate around the axis of the first body 1201, that is... Figure 12a The rotation axis X in the figure rotates by an angle α in the direction indicated by the arrow. In practical applications, the preset angle range can be [0°, 20°], that is, 0°≤α≤20°.

[0121] To enable the second body to automatically adjust to fit the patient, when the second body 1202 rotates relative to the first body 1201, the operating surface 1203 of the second body 1202 can rotate around the rotation axis X. The symmetrical force points on both sides of the rotation axis X form an equal-arm lever. Using the lever principle, when the operating surface contacts the patient, it is subjected to force, which drives the second body 1202 to rotate relative to the first body 1201, achieving automatic adjustment until it maintains balance. This allows the operating surface 1203 to better fit the patient, resulting in balanced force on the patient and achieving a better nursing effect.

[0122] To facilitate understanding, the following will be combined with... Figure 14 The lever principle diagram shown illustrates this. The operating surface can be an axisymmetric structure with the rotation axis X as its axis. Symmetrical force points F1 and F2 exist on both sides of the rotation axis X on the operating surface. Of course, there can be multiple sets of symmetrical force points on the operating surface relative to the rotation axis. The lever arm of force point F1 is L1, and the lever arm of force point F2 is L2. The lever balance condition is: effort * effort arm = resistance * resistance arm, that is, F1•L1 = F2•L2. Since force points F1 and F2 are symmetrical with respect to the rotation axis, the lever arm L1 equals the lever arm L2. In use, as shown in Figure 3, assuming the lever arm of force point F1 is L1*Cosθ and the lever arm of force point F2 is L2*Cosθ, since L1=L2, the effort arm and resistance arm are equal during rotation. Since F1 is greater than F2, in order to maintain balance, F1 will cause the second body to rotate counterclockwise until F1=F2, so that the operating surface of the second body is parallel and in contact with the patient. Conversely, assuming F2 is greater than F1, F2 will cause the second body to rotate clockwise until F2=F1, so that the operating surface of the second body is parallel and in contact with the patient, thus achieving automatic adjustment.

[0123] As an optional method, see Figures 13a-13fAs shown in at least part of the illustration, the rotating assembly 1204 may include a bearing 1206 connected to the protruding end 1205, a bushing 1207 sleeved around the bearing 1206, and a bearing retainer 1208 sleeved around the bushing 1207 and fixedly connected to the first body 1201. The bearing retainer 1208 can be fixed to the first body with screws to prevent radial displacement of the bushing 1207 and the bearing 1206. The bearing retainer 1208, bushing 1207, and bearing 1206 may be injection molded into a single structure. Furthermore, to prevent axial displacement of the rotating assembly, the rotating assembly may also include a second limiting component connected to the protruding end 1205 to limit axial displacement of the protruding end 1205. This second limiting component may include one or more of a bearing anti-drop ring and a retaining ring. Optionally, as... Figure 13a As shown, the second limiting component can simultaneously include a bearing anti-drop ring 1209 and a retaining ring 1210. The bearing anti-drop ring 1209 is fixedly connected to the protruding end 1205, and the retaining ring 1210 can be disposed within a groove in the protruding end. The bearing anti-drop ring 1209 prevents axial displacement of the rotating component, and the retaining ring 1210, adjacent to the bearing anti-drop ring 1209, prevents axial displacement of the bearing anti-drop ring 1209. When the second body moves relative to the first body in the direction of arrow 1, the bearing anti-drop ring and retaining ring move accordingly until they stop moving when they abut against the bearing, effectively preventing axial displacement of the protruding end and thus preventing the second body from detaching from the first body. When the second body rotates relative to the first body via the rotating component, the inner ring of the bearing, the bearing anti-drop ring, and the retaining ring rotate with the rotation of the second body, while the outer ring of the bearing, the bushing, and the bearing retainer remain stationary. Furthermore, as... Figure 13b As shown, the second limiting component can also consist only of the retaining ring 1210. In this case, the extending end 1205 is sequentially fitted with the rotating component and the retaining ring, extending into the machine body. The retaining ring located in the groove is adjacent to the bearing. When the second machine body moves relative to the first machine body in the direction of the arrow, the retaining ring moves accordingly until it stops moving when it hits the bearing, which can effectively prevent the extending end from axially displacing and causing the second machine body to detach from the first machine body.

[0124] To ensure that the second body can rotate within a preset angle range, the nursing device may further include a first limiting component. The first limiting component may include a first limiting member disposed on the second body, and a second limiting member disposed within the first body and cooperating with the first limiting member; the first and second limiting members cooperate to limit the rotation angle of the second body within the preset angle range. The first limiting component can be implemented in several ways: As an optional approach, such as Figures 13a-13fAs shown in at least part of the illustration, the first limiting member can be a first limiting block 1211 disposed on the protruding end 1205, specifically located on the surface of the protruding end that contacts the first body; the second limiting member can be two limiting plates 1212 disposed on the first body 1201. When the second body 1202 rotates relative to the first body 1201, the first limiting block 1211 rotates between the two limiting plates 1212, thereby limiting the rotation angle of the second body. Alternatively, the first limiting member can be a first limiting block disposed on the protruding end, specifically located on the surface of the protruding end that contacts the first body; the second limiting member can be a first limiting groove disposed on the first body, specifically located on the side of the first body adjacent to the protruding end. When the second body rotates relative to the first body, the first limiting block rotates within the first limiting groove, thereby limiting the rotation angle of the second body.

[0125] As another alternative, a recess can be provided in the first body, and the second body is at least partially embedded in the recess; the shape of the recess matches the shape of the embedded part of the second body, so that the embedded part of the second body is hidden in the recess; the first limiting member can refer to a second limiting block provided on the embedded part of the second body; the recess is provided with a second limiting groove for accommodating the second limiting block, and the second limiting block rotates in the second limiting groove to limit the rotation angle of the second body.

[0126] To ensure that the second body can rotate within a preset angle range, as another possible implementation, the nursing device may further include a third limiting block disposed on the second limiting member, and two limiting plates disposed on the first body; the third limiting block rotates between the two limiting plates to limit the rotation angle of the second body. The second limiting member includes a bearing anti-drop ring, and the third limiting block is specifically disposed on the bearing anti-drop ring.

[0127] In a practical application, such as Figures 13a-13f As shown in at least part of the illustration, the second body may include an upper cover 1213 and a lower cover 1214, which are fastened together to form a first cavity. The upper cover 1213 is specifically provided with an operating surface 1203.

[0128] As described above, the nursing device may include at least one nursing system, which may include at least one electrode-based nursing system. The nursing device may also include an electrode assembly connected to one or more electrode-based nursing systems, which share the electrode assembly to provide care to the patient. The one or more electrode-based nursing systems may include, for example, a radiofrequency nursing system, a microcurrent nursing system, etc. Specifically, the operating surface may be provided with through holes for the entry and exit of electrodes in the electrode assembly. The electrode assembly may include multiple electrodes; specific implementations of the electrode assembly can be found in the preceding embodiments and... Figures 3a-3e As shown in the diagram. Optionally, multiple electrodes in the electrode assembly can be located on the same straight line, and the second body can rotate relative to the first body along the electrode arrangement direction.

[0129] Optionally, the electrode assembly may include at least one set of electrode pairs. Figures 12a-12g as well as Figures 13a-13f Taking a set of electrode pairs as an example, each electrode pair may include a first electrode 10 and a second electrode 20, with the first end located inside the second body 1202 and the second end extending out of the operating surface 1203 to contact the patient. The first electrode 10 and the second electrode 20 may be located on the same straight line and distributed symmetrically about the rotation axis. When the operating surface contacts the patient, the first and second electrodes, extending a certain height from the operating surface, become the points of force application. Furthermore, the electrode assembly may also include a third electrode 30, with the first end located inside the second body 1202 and the second end extending out of the operating surface 1203 to contact the patient. The third electrode 30 is located on the rotation axis and is on the same straight line as the first electrode 10 and the second electrode 20.

[0130] As described above, the nursing device may include an elasticity detection system. Each electrode pair and the third electrode can be pressed by the patient and move along the direction of pressure to establish a connection with the elasticity detection system. Each electrode pair and the third electrode can form an electrode set to create at least one electrode set. The control system can, for each electrode set, read the second pressure parameter value applied to the third electrode when the pressure parameter value applied to each electrode pair meets the pressure balance condition, and calculate the candidate elasticity value of the patient based on the second pressure parameter value. Based on at least one candidate elasticity value corresponding to at least one electrode set, the control system can calculate the elasticity value of the patient.

[0131] As described above, the elastic detection system can include at least one set of first pressure detection components and a second pressure detection component, such that each first electrode, each second electrode, and each third electrode can be connected to a pressure detection component. Furthermore, when the electrode assembly includes only one set of electrode pairs and a third electrode, the elastic detection system can specifically include a fourth pressure detection component, which can be connected to the first, second, and third electrodes respectively. And as described above, the fourth pressure detection component can specifically include an "E"-shaped elastic structure.

[0132] like Figures 13a-13fThe diagram shows an electrode assembly including a third electrode and a first and second electrode from a set of electrode pairs. The first, second, and third electrodes are connected to a fourth pressure detection assembly, which includes an "E"-shaped elastic structure 1215. Strain gauges 1200 from a strain detection circuit are mounted on the elastic arms of the elastic structure 1215. The "E"-shaped elastic structure may include a support and three elastic arms, the second ends of which are suspended. The first, second, and third electrodes are each connected to the second end of an elastic arm, and each elastic arm is connected to a strain detection circuit. Optionally, the first end of an electrode in the electrode assembly can be a hollow structure, fitted with an insulating sleeve, and a conductive sheet or the like can be disposed outside the insulating sleeve. The elastic structure can be fixedly connected to the first end of the corresponding electrode by screws, the screws passing sequentially through the conductive sheet, the elastic structure, the insulating sleeve, and to the hollow structure of the corresponding electrode. Figures 13a-13f Taking the first electrode 10, the second electrode 20, and the third electrode 30 as examples, the screw 1216 can pass sequentially through the elastic structure 1215, the insulating sleeve 1217, and finally through the hollow structure of the corresponding electrode. A conductive sheet 1218 can be provided outside the insulating sleeve. The specific implementation of the elastic detection system can be found in the previous text and will not be repeated here.

[0133] The device comprises a first set of components located within a first housing, and a second set of components located within a second housing, specifically within a first cavity formed by the snap-fitting of an upper and lower cover. The second set of components may include at least one care system and components from at least one detection system. The first set of components may include at least one care system, components from at least one detection system, a control system, a power supply system, a charging system, etc. The second set of components may include, for example, the electrode assembly, elastic structure, and strain gauges mounted on the elastic structure. If at least one care system includes an optical care system and a vibration care system, the second set of components may further include a light assembly 1300 from the optical care system and a motor 1400 from the vibration care system. Specifically, the upper cover may house the electrode assembly, elastic structure, strain gauges, and light assembly, while the lower cover may house electrodes, a flexible circuit board, etc. The light assembly of the optical care system can provide optical care, such as infrared or blue light, while the motor of the vibration care system can drive the second housing to vibrate, providing a massage function, etc.

[0134] like Figures 13a-13fAs shown in at least part of the illustration, the first part of the components is electrically connected to the second part of the components via a flexible circuit board 1219 passing through the protruding end. The second part of the components is deployed on the circuit board 1500 of the first body. When the second body rotates relative to the first body, the flexible circuit board 1219 can deform accordingly. Using a flexible circuit board for electrical connection saves space compared to traditional wire connections, and the wiring is neat and convenient for assembly. The flexible circuit board 1219 connects the first and second bodies through the hollow portion of the protruding end. Specifically, the flexible circuit board 1219 is welded to the conductive plates 1218 on both sides of the insulating sleeve, and an electrical connection is formed through the conductive plates, screws, and electrodes. Simultaneously, the exposed pads of the flexible circuit board 1219 can be electrically connected to the motor via wires. Furthermore, the flexible circuit board 1219 is also electrically connected to the lighting assembly 1300. The flexible circuit board portion at the protruding end can have a certain amount of allowance to facilitate deformation of the flexible circuit board when the second body rotates relative to the first body.

[0135] In addition, such as Figure 12a In the middle, a waterproof coating 1220 covering the operating surface can be provided in the upper cover, and the waterproof coating has through holes for the electrodes in the electrode assembly to enter and exit. Furthermore, a light-transmitting area 1221 can be provided on the operating surface, and the light assembly 1300 of the optical care system is deployed in the second body, allowing the light to illuminate the patient through the light-transmitting area.

The indicators can be represented by patterns and / or text; alternatively, the display area can be equipped with lighting components, using different colored lights to represent different indicators. The control area 1223 can provide corresponding operation controls, such as power on / off, mode switching, and parameter settings. This control panel can be specifically installed on the outer shell of the first unit near the second unit.

[0136] Furthermore, the charging system in this embodiment can be a wired charging system, which connects to an external power source via a charging base and charges the power supply system. The wired charging system may include a magnetic assembly and a charging base. A first end of the first body is connected to a second body, and the second end of the first body may have a magnetic structure. The charging base also has a magnetic structure, so that when the second end of the first body is placed on the charging base, it is fixed to the charging base by the attraction of the two magnetic structures. The charging base can then charge or supply power to the power supply system. In another embodiment of this application, the charging system can be a wireless charging system, which can be implemented according to wireless charging standards.

[0251] In one possible design, the above-mentioned care device can be implemented as a beauty instrument. The corresponding principles and technical effects can be found in the relevant instructions for care devices, which will not be elaborated here.

[0252] Application Scenario 1 When the skincare device is a beauty instrument, the following example illustrates how a user can use it to test facial elasticity. User Wang Er owns a beauty instrument that is registered, authenticated, and network-connected to his mobile app and cloud server. Wang Er turns on the beauty instrument via its control panel. After powering on, the device prompts him to pair it with his phone via Bluetooth. Once pairing is successful, the device prompts him to select a mode. Wang Er selects the skin elasticity testing mode using the buttons on the control panel.

[0253] The beauty device's voice prompts Wang Er to place the device's operating surface into his facial skin. The first, second, and third electrodes of the device's head then contact the facial skin. When Wang Er holds the device and presses it against his face, the first, second, and third electrodes receive the pressure from the facial skin and move into the first cavity. Three strain gauges connected to the first, second, and third electrodes respectively receive the pressure and deform. The strain gauges convert this pressure change into a change in electrical signal. After receiving this parameter change, the beauty device's microprocessor compares it with preset parameters. When the parameter changes of the first and second electrodes are within the preset first and second threshold ranges, the microprocessor reads the parameters fed back by the third electrode and calculates the elastic parameters of Wang Er's facial skin.

[0254] The microprocessor controls the storage of the parameter fed back by the third electrode, for example, 60.5, and displays the data 60.5 on the display area. The voice announces that the facial skin elasticity data is 60.5. At the same time, the test result is sent to Wang Er's mobile APP. At this time, Wang Er's mobile APP displays the result of this facial elasticity test as 60.5. On Wang Er's mobile APP, the test time and test result data are recorded in real time. The changes in facial skin elasticity can be observed through the historical change curve.

[0255] Based on these changes in facial skin elasticity, Wang Er can choose suitable skincare products, adjust dietary habits, and develop corresponding fitness plans.

[0256] Application Scenario 2 When the skincare device is a beauty device, the following example illustrates how a user can use a beauty device to detect facial moisture. User Zhang San owns a beauty device that is registered, authenticated, and network-connected with his mobile app and cloud server. Zhang San turns on the beauty device via its control panel. After powering on, the device prompts Zhang San to pair with his phone via Bluetooth. Once pairing is successful, the device prompts Zhang San to select a mode. Zhang San selects the skin moisture detection mode using the buttons on the control panel. The beauty device's voice prompts Zhang San to place the device's operating surface into his facial skin. The first, second, and third electrodes of the device's head then contact the facial skin. When Zhang San presses the device against his face, the first, second, and third electrodes receive the pressure and move into the first cavity. Three strain gauges connected to these electrodes deform under the pressure, converting this pressure change into a change in electrical signal. The device's microprocessor receives this parameter change and compares it with preset parameters. When the parameter change of the third electrode falls within the preset first and second threshold ranges, the microprocessor controls the circuit formed by the first, second, and facial skin components between them to conduct. The microprocessor then acquires the facial skin resistance parameter and calculates the moisture parameters of Zhang San's facial skin. The microprocessor controls the storage of the impedance parameter between the first and second electrodes, for example, 23.7 ohms. This data is displayed on the screen area, and a voice announcement is given that the facial skin moisture level is 23.7 ohms. Simultaneously, the test result is sent to Zhang San's mobile app. Zhang San's app then displays the facial moisture test result as 23.7 ohms. The app records the test time and result data in real time, allowing users to observe changes in facial skin moisture through historical data curves. Based on these changes, Zhang San can choose suitable skincare or cosmetic products, adjust dietary habits, increase or decrease water intake, regulate indoor humidity, and develop appropriate fitness plans.

[0257] Application Scenario 3 When the care device is a beauty instrument, the following example illustrates how a user can use the microcurrent mode of a beauty instrument to care for facial skin. User Li Si owns a beauty instrument that is registered, authenticated, and network-connected with his mobile app and cloud server. Li Si turns on the beauty instrument via its control panel. After powering on, the beauty instrument prompts Li Si to pair with his phone via Bluetooth. Once pairing is successful, the beauty instrument prompts Li Si to select a mode. Li Si selects the microcurrent care mode using the buttons on the control panel.

[0258] The beauty device's voice prompts Li Si to place the operating surface of the device into his facial skin. The first and second electrodes of the device's head then contact the facial skin. When Li Si presses the device onto his face, the first and second electrodes receive the pressure from the skin and move into the first cavity. Two strain gauges connected to the first and second electrodes deform under this pressure, converting the pressure change into an electrical signal. The microprocessor controls the circuit formed by the first and second electrodes and the skin between them to conduct. The beauty device applies a certain voltage to the facial skin through the first and second electrodes, allowing current to flow through the skin and providing stimulation, care, and beauty benefits.

[0259] Each microcurrent treatment lasts for 3 seconds. During a single treatment, in addition to applying microcurrent treatment to the two electrodes mentioned above, the device can also apply microcurrent treatment to any two other electrodes, alternating with the two electrodes mentioned above to enhance the treatment effect. After 3 seconds, the device shuts off, and a voice prompt reminds Li Si to move the device. As Li Si moves the device on his face, the microprocessor receives the changes in pressure and parameters of the first and second electrodes caused by this movement and applies microcurrent treatment to the facial skin again. This process continues, allowing Li Si to receive microcurrent treatments on multiple different areas of his face. When Li Si reaches the predetermined maximum number of treatments, for example, 20 times, the device notifies Li Si that the microcurrent treatment is over and switches to the next treatment mode. During multiple microcurrent treatments, the device can apply microcurrent treatment to any two electrodes or alternate between two electrodes to enhance the treatment effect. If Li Si is using the microcurrent mode and the device is removed from his face for too long, such as 10 seconds, the controller will inform Li Si via voice prompt not to remove the device and to continue the treatment.

[0260] When the beauty device is in microcurrent treatment mode, its memory records and stores the treatment area, treatment time, number of treatments, and microcurrent parameters in real time. The microprocessor displays these parameters on the display area and simultaneously sends them to Li Si's mobile app, which records the microcurrent treatment parameters in real time.

[0261] Application Scenario 4 When the skincare device is a beauty device, the following example illustrates how a user can use the red light mode to care for their facial skin. User Chen Wu owns a beauty device that is registered, authenticated, and network-connected with his mobile app and cloud server. Chen Wu turns on the beauty device using its control panel. After powering on, the device prompts Chen Wu via voice to pair with his phone via Bluetooth. Once pairing is successful, the device prompts Chen Wu to select a mode. Chen Wu selects the red light mode using the buttons on the control panel. The beauty device's voice prompts Chen Wu to place the operating surface of the device into his facial skin. The first and second electrodes of the device's head then contact the skin. When Chen Wu presses the device against his face, the first and second electrodes receive the pressure and move inwards. Two strain gauges connected to these electrodes deform under this pressure, converting the pressure change into an electrical signal. The device's microprocessor receives this parameter change and activates the red LED light inside the device's head. The red light shines through the light-transmitting area of ​​the operating surface onto Chen Wu's face, providing stimulation and beautifying effects. Each red light treatment lasts 6 seconds, after which it turns off. A voice prompt then reminds Chen Wu to move the device. As Chen Wu moves the device, the microprocessor receives the pressure and parameter changes in the first and second electrodes and activates the red LED light again. This process is repeated, allowing Chen Wu to receive red light treatments on multiple areas of his face. When Chen Wu reaches the predetermined maximum number of facial treatments, such as 20, the beauty device will notify him that the red light treatment is over and switch to the next treatment mode. During the red light treatment mode, the device's memory records and stores the treatment area, treatment time, number of treatments, and red light LED parameters in real time. The microprocessor displays these parameters on the display area and simultaneously sends them to Chen Wu's mobile app, which also records the red light treatment parameters in real time. After completing the facial red light treatment, Chen Wu can choose suitable skincare or makeup products, adjust his diet, increase or decrease water intake, adjust indoor humidity, and create a corresponding fitness plan.

[0262] Application Scenario 5 When the care device is a beauty instrument, the following example illustrates how a user uses the vibration mode of the beauty instrument to care for facial skin. User Sun Liu owns a beauty instrument that is registered, authenticated, and network-connected to his mobile phone app and cloud server. Sun Liu turns on the beauty instrument via the control panel. After powering on, the beauty instrument prompts Sun Liu to pair with his phone via Bluetooth. After successful pairing, the beauty instrument prompts Sun Liu to select a mode. Sun Liu selects the vibration care mode using the buttons on the control panel. The beauty instrument prompts Sun Liu to place the operating surface of the beauty instrument into his facial skin. The first and second electrodes of the beauty instrument head contact the facial skin. When Sun Liu holds the beauty instrument and presses it against his facial skin, the first and second electrodes receive the pressure from the facial skin and move into the first cavity. Two strain gauges connected to the first and second electrodes respectively receive the pressure and deform. The strain gauges convert this pressure change into a change in electrical signal. After receiving this parameter change, the beauty instrument's microprocessor controls the vibration motor in the first cavity of the beauty instrument head to turn on. The shock wave from the vibration motor causes the beauty instrument head to vibrate. This vibration is transmitted to Sun Liu's facial skin, providing stimulation, care, and beautification effects. Sun Liu uses a facial massager that can perform vibration therapy on multiple different areas of the face. When the vibration therapy time reaches the preset limit, such as 5 minutes, the massager alerts Sun Liu that the therapy is finished and switches to the next mode. During the vibration therapy mode, the device's memory records and stores the therapy area, therapy time, and vibration motor parameters in real time. The microprocessor displays these parameters on the screen and simultaneously sends them to Sun Liu's mobile app, which records the vibration therapy parameters in real time. After using the facial vibration therapy mode, Sun Liu can select suitable skincare or makeup products, adjust dietary habits, increase or decrease water intake, adjust indoor humidity, and create a corresponding fitness plan.

[0263] Application Scenario Six When the treatment device is a beauty instrument, the following example illustrates how a user can use the radio frequency (RF) mode of a beauty instrument to treat facial skin. User Qianba owns a beauty instrument that is registered, authenticated, and network-connected to their mobile app and cloud server. Qianba turns on the beauty instrument via its control panel. After powering on, a voice prompt reminds Qianba to pair the beauty instrument with their phone via Bluetooth. Once pairing is successful, the beauty instrument prompts Qianba to select a mode, which Qianba selects using the buttons on the control panel. The beauty instrument prompts Qianba to place the operating surface of the beauty instrument into their facial skin, and multiple electrodes from the electrode assembly on the beauty instrument head contact the facial skin. Qianba holds the beauty instrument and presses it against their facial skin. The beauty instrument outputs RF energy to the facial skin through the multiple electrodes, enhancing skin elasticity and reducing wrinkles. The larger treatment area also improves the treatment effect. After the RF treatment on the current facial area is complete, a voice prompt reminds Qianba to move the beauty instrument. Qianba moves the beauty instrument across their face to perform RF treatments on multiple different areas of their face.

[0264] Application Scenario 7 When the skincare device is a beauty instrument, the following example illustrates how a user uses a beauty instrument for skin testing. User Zhao Jiu owns a beauty instrument that is registered, authenticated, and network-connected to his mobile app and cloud server. Zhao Jiu operates the control panel of the beauty instrument to turn it on. After the beauty instrument is turned on, a voice prompt reminds Zhao Jiu to pair it with his phone via Bluetooth. After successful pairing, the beauty instrument's voice prompt reminds Zhao Jiu to select a mode. The beauty instrument offers detection modes such as skin elasticity and moisture testing, as well as treatment modes such as microcurrent therapy, vibration therapy, optical therapy, and radio frequency therapy.

[0265] Taking Zhao Jiu's selection of the skin elasticity detection mode as an example, Zhao Jiu can select this mode via the buttons on the control panel. The beauty device's voice prompts Zhao Jiu to bring the operating surface of the device head into contact with his facial skin. One end of the first and second electrodes of the beauty device extends out of the operating surface to contact the facial skin. The operating surface has an axisymmetric structure with the rotation axis as its axis. The first and second electrodes are symmetrically distributed on both sides of the rotation axis, serving as symmetrical force points when the operating surface contacts the facial skin, forming an equal-arm lever. Based on the lever principle, the first and second electrodes automatically adjust the beauty device head according to the received facial pressure, causing the beauty device head to rotate automatically relative to the beauty device handle, ensuring that the operating surface of the head fits snugly against the face. The beauty device head can rotate relative to the handle via a connected bearing, a bushing surrounding the bearing, and a bearing fixing bracket surrounding the bushing and fixed to the beauty device handle.

[0266] When Qian Jiu holds the beauty device and presses it against her facial skin, the first and second electrodes adaptively adjust the head to maintain a close fit to her face. Simultaneously, the first, second, and third electrodes of the device receive pressure from the facial skin and move into the first cavity. Three strain gauges connected to the first, second, and third electrodes deform under this pressure, converting the pressure changes into electrical signal changes. The device's microprocessor calculates the elastic parameters of Qian Jiu's facial skin based on these parameter changes. When Qian Jiu moves the beauty device by holding the handle, the head automatically rotates to fit her face according to the facial contours, allowing for continued detection of other areas of the face and improving the detection effect.

[0267] Application Scenario 8 When the skincare device is a beauty instrument, the following example illustrates how a user uses a beauty instrument for skincare. User Zhou Shi owns a beauty instrument that is registered, authenticated, and network-connected to his mobile app and cloud server. Zhou Shi turns on the beauty instrument via its control panel. After powering on, the beauty instrument prompts Zhou Shi to pair with his phone via Bluetooth. Once pairing is successful, the beauty instrument prompts Zhou Shi to select a mode. The beauty instrument offers detection modes such as skin elasticity and moisture detection, as well as treatment modes such as microcurrent therapy, vibration therapy, optical therapy, and radio frequency therapy.

[0268] Taking the microcurrent care mode selected on Zhou Shi's tenth birthday as an example, Zhou Shi can select the microcurrent care mode through the buttons on the control panel. The beauty device's voice prompts Zhou Shi to contact the operating surface of the device head with the facial skin. One end of the first and second electrodes of the beauty device extends out of the operating surface to contact the facial skin. The operating surface has an axisymmetric structure with the rotation axis as the axis of rotation. The first and second electrodes are symmetrically distributed on both sides of the rotation axis, serving as symmetrical force points when the operating surface contacts the facial skin, forming an equal-arm lever. Based on the lever principle, the first and second electrodes automatically adjust the beauty device head according to the received facial pressure, causing the beauty device head to rotate automatically relative to the beauty device handle, ensuring that the operating surface of the head is in close contact with the face. The beauty device head can rotate relative to the handle through a connected bearing, a bushing sleeve surrounding the bearing, and a bearing fixing bracket surrounding the bushing and fixed to the beauty device handle.

[0269] When Zhou Shi presses the beauty device onto his face, the first and second electrodes adaptively adjust the head to maintain a close fit to his face. Simultaneously, the first and second electrodes receive pressure from the facial skin and move into the first cavity. Two strain gauges connected to the first and second electrodes deform under this pressure, converting the pressure change into an electrical signal. The microprocessor controls the circuit formed by the facial skin between the first and second electrodes, allowing the beauty device to apply a voltage to the facial skin. This current flows through the skin, stimulating and beautifying it. Each microcurrent treatment lasts for 3 seconds, after which it turns off. A voice prompt reminds Zhou Shi to move the device. As Zhou Shi moves the device, the head automatically rotates to fit his face, allowing for further treatment of other areas and enhancing the overall effect.
