[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention is further described in detail below in conjunction with the embodiments and accompanying drawings. Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the description of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0027] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] like Figure 1 、 Figure 2 、 Figure 3As shown in FIG. 1 , it is a schematic diagram of the structure of the anti-itch device 100 provided in this preferred embodiment. The anti-itch device 100 includes a housing 110, an electrical connection interface 120, a heating element (heating area) 130, a control circuit board 140, a touch sensor 141, a temperature sensor 142, a highlight indicator light 150, and a fixing plate 160. The heating element 130 protrudes from the surface of the housing 110. The heating element 130 uses a ceramic heating plate. The touch sensor 141 is located in the peripheral area around the heating element 130. The touch detection surface of the touch sensor 141 (the contact surface for detecting the user's skin) is slightly lower than the outer surface of the heating element 130 (the surface in contact with the user's skin). The purpose of setting the touch detection surface of the touch sensor 141 lower than the outer surface of the heating element 130 is to ensure that the heating element 130 contacts the user's skin more completely. The temperature sensor 142 is located in the middle of the heating element 130. The side of the temperature sensor 142 is surrounded by the heating element 130, and the temperature measurement area of ​​the temperature sensor 142 protrudes from the outer surface of the heating element 130. In this embodiment, the temperature sensor 142 is an infrared temperature sensor, and the infrared radiation collection area protrudes from the surface of the heating element 130. A heat insulation element 170 is provided between the heating element 130 and the temperature sensor 142. The heat insulation element 170 does not block the temperature measurement area of ​​the temperature sensor 142. The purpose of providing the heat insulation element 170 is to prevent the heating element 130 from affecting the measurement results of the temperature sensor 142 when it is heated. The electrical connection interface 120 is a commonly used Type-C model, which is convenient for connecting to the charging interface of a power bank, mobile phone, or other compatible smart device. The control circuit board 140 is electrically connected to the electrical connection interface 120 to obtain electrical energy. The fixing plate 160 is fixed to the housing 110 to fix the heating element 130. That is, the heating element 130 is fixed to the fixing plate 160, and a portion of the temperature sensor 142 is also fixed to the fixing plate 160.

[0029] The control circuit board 140 is provided with a memory 143, a timer 144, and a microprocessor 145. The memory 143 stores a plurality of instruction codes. The microprocessor 145 can call the instruction codes stored in the memory 143 to execute the following method operations: a. Detecting whether the touch sensor 141 (designated area) is in contact with the user's skin. If so, step b is executed. When the proportion of touch sensors 141 in contact with the user's skin reaches 80% or more, contact is determined. b. The timer 144 detects the duration of contact between the touch sensor 141 and the skin, and the temperature sensor 142 detects the temperature of the contacted skin portion. If the measured temperature is within a predetermined range and the continuous contact time reaches a set time, the anti-itch device 100 is turned on and operated. The predetermined range is the normal human body temperature range (e.g., 34-37°C), and the set time is at least 3 seconds. c. The heating element 130 (heating area) is automatically energized and heated to a set temperature (e.g., a value within the range of 50°C + 2) and maintained for a set heating time. In this embodiment, the measurement of whether the heating element 130 has reached the set temperature is achieved by a temperature detection unit (such as a thermistor NTC) built into the heating element 130. Since the touch sensor 141 must be in contact with the human skin for more than 80% to be considered in contact, the touch sensor 141 is located outside the periphery of the heating element 130 to better ensure that the heating element 130 can better contact the skin, thereby effectively heating the skin.

[0030] When the anti-itch device 100 is powered on, the high-brightness indicator light 150 begins to display the device's operating status. The device constantly monitors the temperature of the skin contact area. The high-brightness indicator light 150 allows the user to clearly see the bite area and understand the specific situation even in dimly lit outdoor environments. The high-brightness indicator light 150 can be illuminated continuously, flashing, or emitting different colors to provide different prompts, indicating different device statuses.

[0031] In step c, the power supply size of the heating element 130 (heating area) is controlled in real time according to the skin temperature measured at all times, so that it reaches the set temperature within the specified heating time (such as 2 seconds or 3 seconds), thereby achieving the purpose of allowing the heating element 130 to heat up quickly and stably.

[0032] The operation method for maintaining the heating time in step c is to control the subsequent heating power of the heating element 130 (heating area) in real time based on the skin temperature of the heated area (the area covered by the heating area) after the heating element 130 (heating area) reaches the set temperature, so that the skin temperature maintains the predetermined target temperature until the heating time is met. The target temperature can be the set temperature or slightly lower than the set temperature. Such a setting can use the feedback of multiple consecutive skin temperature data to ensure that the skin area will not be overheated or underheated during the heating process, maintain the target temperature to reach the heating time, and ensure that the skin is heated to meet the functional requirements.

[0033] like Figure 4 As shown, it is a schematic diagram of the working method of the antipruritic device 100 corresponding to the above embodiment. The method can also be applied to other types of skin thermal therapy equipment as needed. The specific implementation process includes the following steps:

[0034] S101, detecting whether the designated area contacts the user's skin, if so, executing step S102, otherwise executing step S101. In this embodiment, when the proportion of the touch sensor 141 contacting the user's skin reaches 80% or more, it is determined to be contact.

[0035] S102, detect the time of contact with the skin and the temperature of the skin of the contacted part. If the measured temperature is within the predetermined range (34-37°C) and the continuous contact time reaches the set time (more than 3 seconds), execute step S103.

[0036] S103, the device (antipruritic device 100) is turned on and operated. After the antipruritic device 100 is turned on and operated, the temperature of the contacted part of the skin is detected from time to time.

[0037] In step S104, the heating area is powered on and automatically heated to the set temperature (50°C) and maintained for the desired duration. The power supply to the heating area is controlled in real time based on the measured skin temperature, ensuring that the set temperature is reached within the heating time (3 seconds), thereby achieving rapid and stable heating of the heating area.

[0038] The method of maintaining the heating time is to control the subsequent heating power of the heating area in real time based on the skin temperature of the heated area (the skin area covered by the heating area) after the heating area reaches the set temperature, so that the skin temperature maintains the predetermined target temperature until the heating time is met. The target temperature can be the set temperature or slightly lower than the set temperature. Such a setting can use the feedback of multiple consecutive skin temperature data to ensure that the skin area will not be overheated or underheated during the heating process, maintain the target temperature for the heating time, and ensure that the skin is heated to meet functional requirements, such as relieving itching.

[0039] With reference to the above embodiment, in other examples, the anti-itch device 100 may also adopt other modes. For example, in other modes, after step a, a step of detecting the ambient temperature is included. In this case, in step c, the power supply to the heating element 130 (heating area) is controlled in real time based on the measured ambient temperature, so that the output power of the heating element 130 (heating area) reaches the set temperature within the specified heating time, thereby achieving the purpose of rapid and stable heating of the heating element 130.

[0040] Specifically, the microprocessor 145 calls the instruction code stored in the memory 143 to perform the following method operations: a. Detect whether the touch sensor 141 (specified area) is in contact with the user's skin. If so, the ambient temperature is detected and step b is executed. b. The timer 144 detects the time the touch sensor 141 is in contact with the skin, and the temperature sensor 142 detects the temperature of the contacted part of the skin. If the measured temperature is within a predetermined range and the continuous contact time reaches the set time, the anti-itch device 100 is turned on and operated. c. The heating element 130 (heating area) is powered on and automatically heated to a set temperature (e.g., a value within the range of 50°C + 2) and maintained for the heating time. The power supply of the heating area is to control the output power of the heating area in real time according to the measured ambient temperature so that it reaches the set temperature within the heating time (3 seconds), thereby achieving the purpose of allowing the heating element 130 to heat up quickly and stably.

[0041] Correspondingly, if Figure 5 As shown, the working method of the antipruritic device 100 is modified as follows:

[0042] S201, detecting whether the designated area contacts the user's skin, if so, executing step S102, otherwise executing step S101. In this embodiment, when the proportion of the touch sensor 141 contacting the user's skin reaches 85% or more, it is determined to be contact.

[0043] S202, detect the ambient temperature, the time of contact with the skin and the temperature of the skin of the contacted part. If the measured temperature is within the predetermined range (34-37°C) and the continuous contact time reaches the set time (more than 3 seconds), execute step S203.

[0044] S203, the antipruritic device 100 is turned on and operated. After the antipruritic device 100 is turned on and operated, the temperature of the contacted part of the skin is detected from time to time.

[0045] In step S204, the heating area is powered on and automatically heated to the set temperature (50°C) and maintained for the desired duration. The heating area's power supply is controlled in real time based on the measured ambient temperature, ensuring that the set temperature is reached within the heating time (3 seconds), thereby achieving rapid and stable heating of the heating area.

[0046] Similarly, referring to the above embodiment, in other examples, the anti-itch device 100 may also adopt a more intelligent smart mode. For example, in the smart mode, after step a, a step of detecting the ambient temperature is included. In step c, the power supply of the heating element 130 (heating area) is controlled in real time based on the measured ambient temperature and the measured skin temperature, so that the output power of the heating element 130 (heating area) is achieved within the specified heating time, thereby achieving the purpose of rapid and stable heating of the heating element 130.

[0047] Specifically, the microprocessor 145 calls the instruction code stored in the memory 143 to perform the following method operations: a. Detect whether the touch sensor 141 (specified area) is in contact with the user's skin. If so, execute step b. b. The timer 144 detects the time the touch sensor 141 is in contact with the skin, and the temperature sensor 142 detects the temperature of the contacted part of the skin. If the measured temperature is within a predetermined range and the continuous contact time reaches the set time, the anti-itch device 100 is turned on and the ambient temperature is detected. c. The heating element 130 (heating area) is powered on and automatically heated to a set temperature (e.g., a value within the range of 50°C + 2) and maintained for a certain period of time. The power supply of the heating element 130 is controlled in real time based on the measured ambient temperature and the skin temperature measured at all times, so that the heating element 130 reaches the set temperature within the specified heating time, thereby achieving the purpose of rapidly and stably heating the heating element 130.

[0048] Correspondingly, if Figure 6 As shown, the working method of the antipruritic device 100 is modified as follows:

[0049] S301: Detect whether the designated area is in contact with the user's skin. If so, proceed to step S102; otherwise, proceed to step S101. In this embodiment, contact is determined when the proportion of touch sensors 141 in contact with the user's skin reaches 90% or more (a larger proportion ensures that the heating element 130 is in more complete contact with the skin).

[0050] S302, detect the time of contact with the skin and the temperature of the skin of the contacted part. If the measured temperature is within the predetermined range (34-37°C) and the continuous contact time reaches the set time (more than 3 seconds), execute step S303.

[0051] S303, the antipruritic device 100 is turned on and operated. After being turned on and operated, the antipruritic device 100 detects the ambient temperature and subsequently detects the temperature of the contacted part of the skin from time to time.

[0052] In step S304, the heating area is powered on and automatically heated to the set temperature (50°C) and maintained for the required heating time. The power supply to the heating area is controlled in real time based on the measured ambient temperature and the skin temperature, ensuring that the set temperature is reached within the specified heating time. This allows the heating area to heat up quickly and stably, while also meeting the requirements of users who demand high accuracy.

[0053] For further improvement of the above embodiment, in other examples, the antipruritic device 100 can also add a mode change scheme. For example, in the mode change scheme, step b can also include detecting the number of times the designated area contacts the skin within a predetermined time, and selecting the set temperature (such as one of 48°C, 49°C, and 50°C) and heating time (one of 3 seconds, 4 seconds, 5 seconds, and 6 seconds) to be reached by the heating area according to the number of times. For example, if the predetermined time is set to 1 second and the number of times the skin is contacted is 2 times, then the operation mode is changed to another mode if the number of times the skin is contacted is 2 times within 1 second; if the number of times the skin is contacted is 1 time within 1 second, then the operation mode is changed to the current mode or the default mode. In this way, different mode settings can be used according to different user groups, such as children and adults have different temperature sensitivities. At this time, the heating element 130 is automatically powered on and heated to the set temperature corresponding to the selected mode, and the heating time is also the heating time corresponding to the selected mode.

[0054] Correspondingly, if Figure 7 As shown, the working method of the antipruritic device 100 can be optimized as follows:

[0055] S401, detecting whether the designated area contacts the user's skin, if so, executing step S102, otherwise executing step S101. In this embodiment, when the proportion of the touch sensor 141 contacting the user's skin reaches 80% or more, it is determined to be contact.

[0056] S402, detect the time of contact with the skin and the temperature of the skin of the contacted part. If the measured temperature is within the predetermined range (34-37°C) and the continuous contact time reaches the set time (more than 3 seconds), execute step S103.

[0057] S403, the device (antipruritic device 100) is turned on and operated. After being turned on and operated, the antipruritic device 100 constantly detects the temperature of the contacted part of the skin.

[0058] Step S404 detects the number of times the designated area touches the skin within a predetermined time, and selects the set temperature and heating duration for the heating area based on the number of times. If the contact is once, step S406 is executed; if the contact is multiple times within 1 second, step S405 is executed.

[0059] S405, switching to another working mode, selecting the corresponding temperature in this mode as the set temperature and the corresponding duration as the heating duration.

[0060] S406, if the number of times of contact with the skin within 1 second is 1, the device operates in the current mode or the default mode, and the corresponding temperature in the mode is selected as the set temperature and the corresponding time is selected as the heating time.

[0061] S407: The heating area is powered on and automatically heated to the set temperature (50°C) and maintained for the desired duration. The power supply to the heating area is controlled in real time based on the measured skin temperature, ensuring that the set temperature is reached within the heating time (3 seconds), thereby achieving rapid and stable heating of the heating area.

[0062] Since the solution provided by the above embodiment can determine whether the device is turned on and running based on the skin contact time and the temperature of the skin contact part, it solves the problems of inconvenience in use or easy misoperation in the prior art.

The program may be stored in a computer-readable storage medium, and the above-mentioned storage medium may be a read-only memory, a disk, or an optical disk, etc.
