[0035] Embodiment 1

[0036] See also Figure 1 As shown, a nursing instrument includes: a main control board 10, a heating device 11, a temperature conductor 14 and a temperature sensor; the temperature sensor is connected to the main control board 10 to send the detected heating device temperature and / or skin temperature; the main control board 10 is connected to the heating device 11 to adjust the duty cycle of the heating device 11 according to the temperature detected by the temperature sensor; the temperature conductor 14 is in direct or indirect contact with the heating device 11 to conduct heat conduction.

[0037] In this embodiment, the heating device 11 includes an ultrasonic generator, a radio frequency generator, a heating resistor, a heating film, etc., which are specifically configured according to needs and are not limited in this embodiment.

[0038] See also Figure 2As shown, the temperature sensor includes a skin temperature sensor 12, which is used to detect the skin temperature in real time. In this embodiment, the skin temperature sensor 12 is in contact with the temperature conducting member 14. In specific implementation, the skin temperature sensor 12 is arranged above, below, on the left or on the right of the temperature conducting member 14. In this embodiment, the skin temperature sensor 12 is arranged above the temperature conducting member 14.

[0039] Since the temperature conducting member 14 is in contact with the skin, the temperature of the temperature conducting member 14 is the skin temperature. The skin temperature sensor 12 sends the real-time detected skin temperature to the main control board 10, and the main control board 10 judges the real-time detected skin temperature. If the skin temperature is lower than the first preset value, the duty cycle of the heating device 11 is adjusted to a larger value, such as 100%, to achieve rapid heating; if it is greater than or equal to the second preset value and less than or equal to the third preset value, the duty cycle of the heating device 11 is adjusted to a smaller value, such as 15%, to achieve slow heating to prevent scalding the user; if it is greater than the third preset value, the duty cycle of the heating device 11 is adjusted to 0, that is, the heating device 11 is turned off.

[0040] It should be noted that the above-mentioned duty cycle adjustment can also be adjusted according to the temperature of the heating device 11. The main control board 10 only makes an extreme value judgment on the detected skin temperature, that is, the heating device 11 is controlled to be turned off only when the skin temperature exceeds the third preset value.

[0041] The temperature sensor includes a heating device temperature sensor 13, which is used to detect the temperature of the heating device 11. The heating device temperature sensor 13 is in contact with the heating device 11. In specific implementation, the heating device temperature sensor 13 is arranged above, below, on the left or on the right of the heating device 11. In this embodiment, the heating device temperature sensor 13 is arranged above the heating device 11.

[0042] The heating device temperature sensor 13 sends the real-time detected heating device temperature to the main control board 10, and the main control board 10 judges the real-time detected heating device temperature. If the heating device temperature is lower than the first preset value, the duty cycle of the heating device 11 is adjusted to a larger value, such as 100%, to achieve rapid heating; if it is greater than or equal to the second preset value and less than or equal to the third preset value, the duty cycle of the heating device 11 is adjusted to a smaller value, such as 15%, to achieve slow heating to prevent scalding the user; if it is greater than the third preset value, the duty cycle of the heating device 11 is adjusted to 0, that is, the heating device 11 is turned off.

[0043] It should be noted that the above-mentioned duty cycle adjustment can also be adjusted according to the skin temperature. The main control board 10 only makes an extreme value judgment on the detected temperature of the heating device, that is, the heating device 11 is controlled to be turned off only when the temperature of the heating device exceeds the third preset value.

[0044] In addition, the main control board 10 can also adjust the duty cycle of the heating device 11 according to the skin temperature and the temperature of the heating device at the same time, which is not specifically limited in this embodiment.

[0045] In this embodiment, in order to speed up the heating speed and prevent the risk of over-temperature, the skin temperature sensor 12 and the heating device temperature sensor 13 are used for temperature feedback at the same time, that is, when any one of the skin temperature sensor 12 or the heating device temperature sensor 13 detects that the temperature exceeds the corresponding preset value, the heating device is adjusted in time to prevent the user's skin from being scalded by over-temperature. Specifically, when the skin temperature sensor 12 detects that the temperature of the skin does not exceed the second preset value, the duty cycle of the heating device 11 is adjusted to a larger gear, which can quickly heat up. The skin temperature sensor 12 and the heating device temperature sensor 13 detect at the same time. When the temperature of the skin temperature sensor 12 is greater than the third preset value or the temperature of the heating device temperature sensor 13 is greater than the third preset value, the heating device is turned off. The second preset value can also be adjusted according to the needs of different skins and different gears. The third preset values ​​of the skin temperature sensor 12 and the heating device temperature sensor 13 are different, and the third preset value of the heating device temperature sensor 13 is higher than the third preset value of the skin temperature sensor 12.

[0046] In addition, the advantage of using both the skin temperature sensor 12 and the heating device temperature sensor 13 for temperature feedback is that, when one of them fails, it can be guaranteed that one can feed back the measured temperature to the main control board 10, and the main control board 10 can control the temperature in time to prevent the user's skin from being burned by excessive temperature.

[0047] In this embodiment, the nursing instrument further includes: a motion sensor 15; the motion sensor 15 is connected to the main control board 10 to send a motion identification signal of the nursing instrument.

[0048] The motion sensor 15 is used to identify the acceleration of the nursing instrument. When the motion sensor 15 detects that the product is stationary or basically remains motionless, it generates an electrical signal and sends it to the main control board 10. The main control board 10 controls the heating device 11 to cut off the output to prevent skin burns or overheating.

[0049] In this embodiment, the nursing instrument further includes: a skin sensing capacitor 16; the skin sensing capacitor 16 is arranged on the surface of the nursing instrument that contacts the skin, and is connected to the main control board 10 to send a sensing signal of contact with the skin.

[0050] The skin sensing capacitor 16 is used to sense whether the skin is in contact. Only after the skin is in contact, the main control board 10 controls the start of heating and the start of temperature / acceleration detection to ensure that the nursing instrument is in an effective working state.

[0051] In this embodiment, the nursing instrument further includes: a gear adjustment switch 17; the gear adjustment switch 17 is connected to the main control board 10 to send the adjustment gear.

[0052] Specifically, the user can adjust the gear according to his or her own skin condition or demand preference, and the main control board 10 regulates the upper and lower limits of temperature and the proportion of the heating device 11 according to the set gear.

[0053] In this embodiment, the temperature conducting member 14 comprises a metal temperature conducting sheet, which is arranged on the surface of the nursing instrument in contact with the skin to heat the skin. The metal temperature conducting sheet has good thermal conductivity and controllable temperature response characteristics.

[0054] It should be noted that the temperature conducting member 14 may also be made of other heat conducting materials, which can be selected according to specific needs and is not limited in this embodiment.

[0055] In addition, the direct contact or indirect contact between the temperature conducting member 14 and the heating device 11 refers to that there is a certain gap between the temperature conducting members 14 or other heat conducting media are arranged between the two for heat conduction. The specific selection is made according to needs and is not limited in this embodiment.

[0056] See also Figure 3 As shown, the nursing instrument of this embodiment includes an upper shell 18 and a lower shell 19, the main control board 10 and the gear adjustment switch 17 can be arranged in the upper shell 18, and the heating device 11, the temperature conducting member 14, the skin temperature sensor 12, the heating device temperature sensor 13, the skin sensing capacitor 16 and the movement sensor 15 are arranged in the lower shell 19. The upper shell 18 and the lower shell 19 are combined to form a handheld nursing instrument, which is convenient for users to carry and use.

[0057] The working principle of the utility model is as follows: the user turns on the device and adjusts the gear, aligns the heating device 11 with the skin and contacts it, the skin sensing capacitor 16 recognizes the change in magnetic flux and detects whether it contacts the skin, the skin temperature sensor 12 starts to detect the skin temperature, and the movement sensor 15 starts to detect the movement of the device; the heating device temperature sensor 13 starts to detect the temperature of the heating device, and after the heating conditions are met, the heating device 11 starts to generate high-frequency vibrations to cause the internal friction of the molecules to generate heat that is transferred to the temperature conduction member 14, and the temperature conduction member 14 contacts the skin to heat the skin.

[0059] See also Figure 4 and Figure 5 As shown, the difference between this embodiment and the first embodiment is that the skin temperature sensor 12 of this embodiment is arranged on the surface of the care instrument in contact with the skin, so that the skin temperature can be directly measured when the care instrument contacts the skin.
