[0030] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-6 The hand tool 10 for a beauty device 100 according to an embodiment of the present invention includes: a housing 11, the housing 11 including a care part 30 and a hand-held part 20.

[0031] Specifically, such as Figures 1-5As shown in the drawings, the nursing part 30 is arranged at one end of the handheld part 20, the nursing part 30 and the handheld part 20 are connected, the handheld part 20 comprises a finger-adapting surface 21 and a palm-adapting surface 25, the finger-adapting surface 21 and the palm-adapting surface 25 are arc surfaces, and the curvature radius of the connection between the finger-adapting surface 21 and the palm-adapting surface 25 is smaller than the curvature radius of any one of the finger-adapting surface 21 and the palm-adapting surface 25.

[0032] In combination Figures 1-5 , the nursing part 30 is the part that directly contacts the skin of the user and is used to perform specific beauty care functions. The handheld part 20 is the part that the user holds, the finger-adapting surface 21 and the palm-adapting surface 25 are arc surfaces, which can better adapt to the natural shape of the human hand and improve the comfort when the user holds. The connection between the finger-adapting surface 21 and the palm-adapting surface 25 adopts a smaller curvature radius, that is, the transition between the finger-adapting surface 21 and the palm-adapting surface 25 is more compact. The connection between the finger-adapting surface 21 and the palm-adapting surface 25 extends along the extension direction of the handheld part 20, the connection between the finger-adapting surface 21 and the palm-adapting surface 25 is respectively arranged on both sides of the handheld part 20 along the radial direction of the handheld part 20, and the curvature radius of the connection between the finger-adapting surface 21 and the palm-adapting surface 25 is smaller, that is, the connection between the finger-adapting surface 21 and the palm-adapting surface 25 slightly protrudes from the finger-adapting surface 21 and the palm-adapting surface 25 along the radial direction of the handheld part 20, so that the user can always feel the connection between the finger-adapting surface 21 and the palm-adapting surface 25 when holding the handheld part 20, which helps to enhance the holding feeling, prevent slipping, and ensure that the user can stably hold the hand tool 10 during operation.

[0033] According to the hand tool 10 for the beauty device 100 provided by the embodiment of the present application, the design of the finger-adapting surface 21 and the palm-adapting surface 25 on the nursing part 30 enables the user to maintain a comfortable holding posture during a long period of use, the smaller curvature radius of the connection between the finger-adapting surface 21 and the palm-adapting surface 25 can provide better friction, prevent the hand tool 10 from slipping off, and improve the convenience and comfort of use, and the smooth arc shape can also improve the appearance of the hand tool 10.

[0034] According to some embodiments of the present application, as shown in Figures 1-5 , the curvature radius of the connection between the finger-adapting surface 21 and the palm-adapting surface 25 has a decreasing trend as a whole in the direction away from the nursing part 30.

[0035] Specifically, the care part 30 is arranged at one end of the handheld part 20 along the axial direction, and the radius of curvature of the connection between the palm-adhering surface 25 and the finger-adhering surface 21 gradually decreases and then gradually increases in the direction away from the care part 30 along the axial direction of the handheld part 20. The gradual design is more in line with the natural curve of the human hand, so that the user can hold the hand tool 10 in a more natural and comfortable way, and reduce fatigue caused by long-time use. With the decrease of the radius of curvature, the increase of the contact area between the connection between the palm-adhering surface 25 and the finger-adhering surface 21 and the hand can increase the local friction, which helps to prevent the hand tool 10 from sliding and improve the stability during operation. The gradual increase of the curvature at the end of the handheld part 20 away from the care part 30 along the axial direction can improve the overall aesthetics of the handheld part 20.

[0036] Therefore, the hand tool with the radius of curvature of the connection between the palm-adhering surface 25 and the finger-adhering surface 21 showing a decreasing trend in the direction away from the care part 30 can help the user to find the most comfortable holding position more easily, so as to ensure that the hand tool 10 remains in a fixed position during use, which is beneficial to perform more delicate and accurate beauty care operations, enhances the stability and accuracy of the operation, and also brings a better holding experience to the user.

[0037] According to some embodiments of the present application, as shown in Figures 1-5 The finger-adhering surface 21 comprises a fingertip-adhering surface 22, a finger-root-adhering surface 23, and a finger-middle-adhering surface 24. The fingertip-adhering surface 22 and the finger-root-adhering surface 23 are oppositely arranged. The finger-middle-adhering surface 24 is arranged between the fingertip-adhering surface 22 and the finger-root-adhering surface 23 and connected with the fingertip-adhering surface 22 and the finger-root-adhering surface 23 respectively. The fingertip-adhering surface 22 and the finger-root-adhering surface 23 are arranged at opposite sides of the finger-middle-adhering surface 24.

[0038] The fingertip-adhering surface 22, the finger-root-adhering surface 23, and the finger-middle-adhering surface 24 are sequentially arranged along the circumferential direction of the handheld part 20, and the fingertip-adhering surface 22, the finger-middle-adhering surface 24, and the finger-root-adhering surface 23 are sequentially connected along the circumferential direction of the handheld part 20. The two side edges of the finger-middle-adhering surface 24 along the circumferential direction of the handheld part 20 are respectively connected with one side edge of the fingertip-adhering surface 22 and the finger-root-adhering surface 23 along the circumferential direction of the handheld part 20. The fingertip-adhering surface 22 and the finger-root-adhering surface 23 are arranged at opposite sides of the finger-middle-adhering surface 24. The other side edges of the fingertip-adhering surface 22 and the finger-root-adhering surface 23 along the circumferential direction of the handheld part 20 are respectively connected with the two side edges of the palm-adhering surface 25.

[0039] Thus, by subdividing the finger-adhering surface 21 into three parts, corresponding to different parts of the finger (the tip, the middle, and the root), the changes in the user's hand shape can be more accurately adapted to, and a more personalized holding experience can be provided. The tip-adhering surface 22 and the root-adhering surface 23 are arranged on opposite sides of the middle-adhering surface 24, and such an arrangement can ensure the stability and balance of the hand tool 10 in different directions, and improve the comfort of the user during long-term use.

[0040] According to some embodiments of the present application, as shown in Figures 1-5 The distance between the tip-adhering surface 22 and the root-adhering surface 23 increases in the direction away from the middle-adhering surface 24; or, the width of the middle-adhering surface 24 increases first and then decreases along the hand-holding portion 20 from the end adjacent to the care portion 30 to the other end away from the care portion 30; or, the width of the middle-adhering surface 24 is smaller than the width of the tip-adhering surface 22, and the width of the middle-adhering surface 24 is smaller than the width of the root-adhering surface 23; or, the cross-sectional area of the hand-holding portion 20 increases first and then decreases in the direction away from the care portion 30; or, the width of the palm-adhering surface 25 increases first and then decreases in the direction from the care portion 30 to the hand-holding portion 20.

[0041] The distance between the tip-adhering surface 22 and the root-adhering surface 23 increases in the direction away from the middle-adhering surface 24, which design can better adapt to the differences in hand shape of different users, and the gradually increasing spacing allows for a larger palm holding space, which can improve the comfort of holding, and also accommodate more diverse and differently sized hand shapes. Along the axis of the hand-holding portion 20, the width of the middle-adhering surface 24 increases first and then decreases from the end of the hand-holding portion 20 connected to the care portion 30 to the other end away from the care portion 30, and the wider part is suitable for corresponding to the position most commonly held by the user, ensuring the maximum contact area and friction in this area, thereby improving the stability of holding. The width of the middle-adhering surface 24 is smaller than the width of the tip-adhering surface 22 and the root-adhering surface 23, and the narrower design of the middle-adhering surface 24 conforms to the natural curve of the human hand, ensuring the comfort of the user when holding. Along the axis of the hand-holding portion 20, the cross-sectional area of the hand-holding portion 20 increases first and then decreases in the direction away from the care portion 30, and the larger cross-sectional area provides a better grip, especially in wet or sweaty conditions, preventing slipping, and such a gradual design can better fit the natural curve of the palm, improving the comfort and stability of holding. In the direction from the care portion 30 to the hand-holding portion 20, the width of the palm-adhering surface 25 increases first and then decreases, and the wider part can cover more of the palm area, providing better support for the user, especially when performing operations that require the application of pressure, and the gradually decreasing width ensures that the hand tool 10 is not too bulky, facilitating operation and carrying.

[0042] Therefore, the distance change trend between the fingertip contact surface 22 and the finger root contact surface 23, the width design of the middle finger contact surface 24, the design of the cross-sectional area of the hand-held part 20, and the design of the palm contact surface 25 are all conducive to improving the comfort of the user when holding the hand tool 10, improving the practicability of the hand tool 10, and bringing a better beauty care experience to the user. The hand tool 10 conforms to the natural curved holding shape, and also has good visual and tactile aesthetics, which is conducive to improving the appearance of the hand tool 10.

[0043] According to some embodiments of the present application, as shown in Figures 1-5 The nursing part 30 includes a convex part 31, which protrudes in the direction of the vertical central axis towards the central area of the nursing part 30 away from the nursing part 30; or, the connection between the nursing part 30 and the hand-held part 20 is formed as a concave surface 32, which is recessed towards the central area of the nursing part 30, and the concave surface 32 extends along the circumferential direction of the nursing part 30.

[0044] The nursing part 30 is provided with a convex part 31 at the other end of the hand-held part 20 away from the nursing part 30 in the axial direction of the hand-held part 20, and the convex part 31 protrudes in the direction of the vertical central axis towards the side where the hand-held part 20 is located.

[0045] Therefore, the convex part 31 is suitable as a physical support point, which facilitates the hanging of the hand tool 10 of the beauty device 100 when not in use, and becomes the storage of the hand tool 10. The connection between the nursing part 30 and the hand-held part 20 is formed as a concave surface 32, and the concave surface 32 extends along the circumferential direction of the nursing part 30, and the setting of the concave surface 32 adds visual aesthetics to the hand tool 10, and increases the appearance of the hand tool 10.

[0046] According to some embodiments of the present application, as shown in Figures 1-5 The nursing part 30 is formed with a nursing surface 33, which is suitable for contacting the skin; the nursing part 30 is formed with a light outlet 34 and at least one detection element interface 35, and the detection element interface 35 is arranged adjacent to the light outlet 34. The surface of the nursing part 30 away from the hand-held part 20 is formed as a nursing surface 33, which is the part directly contacting the skin of the user. The light outlet 34 is responsible for transmitting light of a specific wavelength to the skin to achieve various beauty care functions. The detection element interface 35 (such as temperature sensor, light intensity sensor, etc.) is arranged close to the light outlet 34 to monitor the working state in real time. The sensor can monitor the temperature near the light outlet 34 in real time to prevent overheating caused by long-time use or improper operation.

[0047] Therefore, by optimizing the design of the light outlet 34, it can be ensured that the light is uniformly distributed, and the light outlet 34 designed reasonably can control the light intensity and the irradiation range, avoid excessive exposure or injury to the surrounding skin, and achieve the best cosmetic effect. The detection element interface 35 can detect any potential overheating risk, thereby ensuring the safety of the user, and also reducing the risk of damage caused by overheating and increasing the durability of the product.

[0048] According to some embodiments of the present application, as shown in Figures 1-5 The palm-adapting surface 25 is formed with at least one mounting groove extending between the hand-holding portion 20 and the care portion 30; and further comprising a decorative cover 26 which is detachably coupled with the mounting groove.

[0049] The mounting groove is formed on the palm-adapting surface 25 and extends along the axial direction of the hand-holding portion 20, and extends from the hand-holding portion 20 to the care portion 30. The mounting groove is internally used for mounting or accommodating certain components, and can be covered by the decorative cover 26. The internal components can be hidden by the decorative cover 26, which can maintain the simplicity and beauty of the appearance of the hand tool 10, and prevent external factors from affecting the internal components. When the decorative cover 26 is closed, it can protect the internal components from dust, moisture or other external factors. The decorative cover 26 can be made of a variety of different materials or extensions, providing users with a variety of personalized choices to meet the aesthetic needs of different users, making the hand tool 10 look more fashionable and beautiful, and enhancing the visual recognition of the brand.

[0050] According to some embodiments of the present application, as shown in Figures 1-5 The shell 11 further comprises a connecting portion disposed between the hand-holding portion 20 and the care portion 30, and the connecting portion is formed with at least one heat dissipation opening 36 extending from the care portion 30 to the hand-holding portion 20 in an arc shape; and further comprising electrical elements disposed in the shell 11, and the heat dissipation path of the electrical elements is in communication with the heat dissipation opening 36.

[0051] The connecting portion is located between the hand-holding portion 20 and the care portion 30, and plays a role of connection and support, ensuring the stable connection between the hand-holding portion 20 and the care portion 30. The connecting portion has the heat dissipation openings 36 on both sides in a direction perpendicular to the axis of the hand-holding portion 20, and the heat dissipation openings 36 extend from the care portion 30 to the hand-holding portion 20 in an arc shape, forming an effective heat dissipation path. The heat generated by the electrical elements can be conducted to the heat dissipation opening 36 through the internal heat dissipation path, and finally discharged to the outside of the hand tool 10. The part of the connecting portion extending to the connecting portion of the finger-adapting surface 21 and the palm-adapting surface 25 is similar or identical to one side edge of the heat dissipation opening 36.

[0052] Therefore, the existence of the connecting portion enhances the structural integrity of the entire hand tool 10, ensuring that no looseness or separation occurs during use. The design of the connecting portion can provide a smooth transition area, making the appearance of the hand tool 10 more smooth and natural, and improving the comfort of holding. The arc-shaped heat dissipation port 36 can guide hot air to be discharged along a predetermined path, avoiding heat concentration in a certain area, thereby improving the heat dissipation efficiency. By directly connecting the heat dissipation path of the electrical element to the heat dissipation port 36, efficient heat conduction and dissipation are achieved, ensuring that the electrical element works within a safe temperature range. Reasonable arrangement of the electrical element and its heat dissipation path can realize more compact product design without sacrificing performance, saving space and maintaining aesthetics. Effective heat dissipation design reduces the failure rate caused by high temperature, improving the overall reliability of the product.

[0053] According to some embodiments of the present application, as shown in Figure 6 Further comprising: a filter structure, the filter structure is arranged at the heat dissipation port 36; and / or, the filter structure is arranged in the shell 11, and the filter structure is opposite to the heat dissipation port 36.

[0054] In some embodiments, the filter structure is directly installed at the heat dissipation port 36, effectively preventing external dust and fine particles from entering the interior of the device through the heat dissipation port 36, and protecting the electrical element from pollution and damage. Alternatively, the filter structure is arranged inside the shell 11 and is arranged opposite to the heat dissipation port 36, and the filter structure is used to purify the air sucked or discharged from the heat dissipation port 36, ensuring the cleanliness of the internal environment. Alternatively, the heat dissipation port 36 and the interior of the shell 11 are both provided with filter structures, and the two layers of filter structures inside and outside can provide more comprehensive protection, ensuring that even if a small amount of dust enters, it can be filtered out again.

[0055] Therefore, by arranging the filter structure at the heat dissipation port 36 and / or in the shell 11, the filter structure can effectively block dust and other particulate matters, protect the electrical element, and prolong the service life of the device. Clean air flow helps to improve the heat dissipation efficiency, ensure that the device works within a safe temperature range, and improve the overall performance.
