[0036] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0037] In the field of skin care, in order to achieve the temperature sensing function, designers have adopted the technology of heating through a heating component. However, there is a significant problem with the related technology: when the heating component is heated, a large temperature difference will occur between the electrodes of the skin care device. This not only affects the beauty effect, but also affects the user experience. Therefore, designing a skin care device that takes into account user experience, safety and beauty effects has become an urgent problem to be solved, so as to ensure that the care device can evenly distribute heat while providing a temperature sense, so as to have a safer care method, achieve better care effects and better user experience.

[0038] See also Figure 1 , Figure 2 The embodiment of the utility model provides a care head 100, which is applied to a skin care device 1000. The care head 100 comprises: a housing 10, an electrode assembly 20 and a heating assembly 30, wherein the electrode assembly 20 and the heating assembly 30 are arranged at relative positions of the housing 10; the electrode assembly 20 comprises a plurality of finger electrodes 21, and the areas of the plurality of finger electrodes 21 are the same or different; the heating assembly 30 is used to generate heat, so that the care head 100 can exert a temperature effect when it is attached to the skin; please refer to Figure 3 The heating component 30 includes a plurality of heating resistors 31 connected in series, each heating resistor 31 being arranged corresponding to a finger electrode 21 ; the resistance value of each heating resistor 31 is positively correlated with the area of ​​the corresponding finger electrode 21 .

[0039] The care head 100 of the utility model embodiment includes a shell 10, an electrode assembly 20 and a heating assembly 30, wherein the electrode assembly 20 and the heating assembly 30 are arranged at relative positions of the shell 10, and the shell protects the components inside the care head. The electrode assembly 20 includes a plurality of finger electrodes 21, which refer to the components in the care head 100 used to contact the skin. The width of the finger electrodes 21 is determined according to the average width of an adult human finger. A plurality of straight lines along the length direction of different finger electrodes can intersect at one point, so that the finger electrodes 21 can simulate the distribution of fingers when a human hand is open. The ends of some finger electrodes 21 are curved to imitate the fingertips of the fingers. The areas and shapes of these finger electrodes 21 are the same or different. The heating assembly 30 is used to generate heat so that when the care head 100 contacts the skin, a comfortable temperature effect can be applied. This temperature effect not only enhances the effect of skin care, but also improves the overall experience of the user. By precisely controlling the temperature output of the heating component 30, the device can ensure that during the care process, the skin feels gentle and pleasant warmth, rather than overheating or discomfort. In the heating component 30, multiple heating resistors 31 are arranged in series (referring to multiple resistors connected in series, or a long resistor is arranged in a certain arrangement to form multiple heating resistors 31), and each heating resistor 31 corresponds to a finger electrode 21. This design ensures that each electrode can generate uniform heat underneath it, thereby providing a comfortable temperature sensation when the care head 100 fits the skin. The resistance value of each heating resistor 31 is positively correlated with the area of ​​the corresponding finger electrode 21, which means that electrodes with larger areas will have higher resistance values, thereby generating more heat. This design allows the heat output to be adjusted according to different electrode areas, further optimizing the uniformity of heat distribution and the care effect.

[0040] The resistance value of each heating resistor 31 is positively correlated with the area of ​​its corresponding finger electrode 21. This design ensures that the temperature sensation on the finger electrode 21 is basically consistent. This consistency not only significantly enhances the beauty effect, but also greatly improves the user experience. By accurately matching the resistance value of the resistor wire with the electrode area, the device can achieve uniform heat distribution, avoiding the problem of local overheating or overcooling, thereby providing users with more comfortable and effective skin care during use.

[0042] In this way, the shell 10 is at least partially transparent, and this design enhances the aesthetics of the device. The electrode assembly 20 is deployed on the surface of the shell 10, so that it can directly contact the skin and play its care role. At the same time, the heating component 30 is cleverly configured on the inner side of the shell 10, and is arranged opposite to the electrode assembly 20. This layout makes it possible for the electrode assembly 20 to at least partially block the heating component 30 when observed from the outside of the shell 10. Such a design not only ensures the safety and concealment of the heating component 30, but also prevents the user from directly contacting the heating component 30, thereby improving safety during use. Overall, this design takes into account aesthetics, practicality and safety, and provides users with a more comfortable and reassuring skin care experience.

[0044] Thus, the surface of the housing 10 includes electrode grooves 11, which are used to accommodate the electrode assembly 20, ensuring that the surface of the electrode assembly 20 is flush with the surface of the housing 10, so as to improve the touch feeling of the human body when the housing 10 and the electrode assembly 20 are attached to the face. Figure 5 The outer shell 10 includes a protrusion 12 formed on the side wall of the electrode groove 11, and the protrusion 12 is used to engage the electrode assembly 20, so that the electrode assembly 20 fits more firmly with the outer shell 10, and can also prevent liquid from entering the interior of the care head 100. The heating component 30 is designed to fit on the inner surface of the outer shell 10. When the heating component 30 is working, the heat generated will be transferred to the electrode assembly 20 through the outer shell 10. This heat transfer method is not only efficient, but also safe, because it avoids the risks that may be caused by direct contact of the heating component 30 with the skin. At the same time, this design also helps to achieve uniform heat distribution, further improving the care effect and user experience. Overall, this design achieves the optimal coordination of the electrode assembly 20 and the heating component 30 through a sophisticated structural arrangement, which not only ensures the care effect, but also takes into account the safety and comfort during use.

Next, the resistance value of each heating resistance wire 31 is determined according to the ratio of the area of ​​its corresponding finger electrode 21 to this preset area. This method ensures that each electrode generates appropriate heat, thereby achieving uniform heat distribution throughout the care head 100. Such a design not only improves the beauty effect, but also enhances the user's comfort and satisfaction. By accurately matching the resistance value of the heating resistance wire 31 with the area of ​​the finger electrode 21, the device can adjust the heat output according to different electrode sizes, further optimizing the uniformity of heat distribution and the care effect.

[0047] In some embodiments, the total resistance of the heating assembly 30 is a preset resistance value, and the resistance value of each heating resistance wire 31 is determined according to the preset resistance value and the ratio.

[0048] In this way, the total resistance of the heating component 30 is set to a preset resistance value, which is set according to the overall heat output required by the device and safety considerations.

This method ensures that each resistance wire can generate an appropriate amount of heat, thereby achieving uniform heat distribution throughout the care head 100. In this way, the device can adjust the heat output according to different electrode areas, further optimizing the uniformity of heat distribution and the care effect. This design not only improves the beauty effect, but also enhances the user's comfort and satisfaction. At the same time, the setting of the preset resistance value also ensures the safety and stability of the device, avoiding overheating or other potential safety risks.
