Description

Technical Field

[0001] This application relates to the field of portable skin treatment devices. More specifically, this application relates to a skin treatment apparatus. Background Technology

[0002] Skin inflammation and diseases, such as itching caused by insect bites and acne, are common health problems that cause discomfort and distress to patients. Traditional treatments usually rely on topical or oral medications, which, while effective, may have side effects or be unsuitable for certain individuals. In recent years, treatments based on physical principles have gained increasing attention, among which heated antipruritic devices, as a non-drug therapy, relieve itching symptoms through localized heat therapy.

[0003] The working principle of a heated itch relief device is to heat the contact surface of the device, which comes into contact with the affected skin, to a certain temperature. This heat decomposes or inactivates the chemical substances on the skin that cause itching, thereby relieving the itch. Additionally, this heat effect can interfere with the transmission of itch signals through nerves, causing the nerves in the skin to react to the heat stimulus, thus weakening the itching sensation. Because the heated itch relief device is based entirely on physical principles and does not rely on any chemical components, it has a high degree of safety.

[0004] However, in practical use, especially in dark environments (such as outdoors at night or indoors without lights), users may find it difficult to accurately align the contact surface of the anti-itch device with the affected area. To address this issue, some anti-itch devices have incorporated a light indicator function. For example, a design with an opening in the center of the contact surface allows light to shine out, forming a beam that serves both as illumination and aiming. While these designs improve the user experience to some extent, they still have limitations. For instance, due to the limited diameter of the contact surface or heating element, the opening in the center of the contact surface is usually small, resulting in poor illumination. Additionally, the aforementioned setup completely blocks the light source after the contact surface comes into contact with the skin, making it difficult for users to observe the area surrounding the affected area.

[0030] The specific embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0031] Example 1

[0032] like Figure 1 As shown in Figure 3, this application provides a skin treatment device 100, which includes a body portion 101 and a treatment portion 102 disposed at a first end of the body portion 101. The treatment portion 102 has a treatment surface 1021 for applying heat to the object being treated. The skin treatment device 100 also includes a light-emitting portion 103, which has a light-emitting surface 1031 for emitting light into the environment. The light-emitting surface 1031 and the treatment surface 1021 face the same side of the body portion, and the light-emitting surface 1031 is lower than the treatment surface 1021.

[0033] In this design, the skin treatment device 100 includes a body portion 101 enclosed by a housing and a treatment portion 102 disposed at a first end of the body portion 101. The treatment portion 102 has a treatment surface 1021. In use, the treatment surface 1021 is brought into direct contact with the affected area of ​​the skin, allowing heat from the treatment surface 1021 to be applied to the treated area, thereby relieving the user's itching symptoms. The skin treatment device 100 also includes a light-emitting portion 103 disposed on the body portion 101 to provide illumination for the user. The light-emitting portion 103 has a light-emitting surface 1031 for emitting light into the surrounding environment, wherein the light-emitting surface 1031 and the treatment surface 1021 face the same side of the body portion, and the light-emitting surface 1031 is lower than the treatment surface 1021. This design allows the light-emitting portion 103 to provide illumination so that the user can aim the treatment surface 1021 at the affected area when using the skin treatment device 100 in a dark environment. Furthermore, if the light-emitting surface 1031 and the treatment surface 1021 are on the same surface, the user may have difficulty accurately aligning the treatment surface 1021 with the affected area (e.g., aligning the light-emitting surface with the affected area), especially when a large light-emitting surface is used. This problem is avoided when the light-emitting surface 1031 is lower than the treatment surface 1021. In addition, when the treatment surface is aligned with the affected area, the light-emitting surface 1031 is not obstructed and can still provide illumination for the user to observe the area around the affected area.

[0034] In the above-described scheme, the treatment surface 1021 is the outer surface of the heating ceramic sheet. The heating ceramic sheet generates heat when energized, and its outer surface is used for direct contact with the affected area. In some alternative embodiments, the treatment surface may also be a surface structured from other materials with thermal conductivity, which can conduct heat from the heating element to the affected area. For example, the heating element may be a heating wire or a heating ceramic sheet, and the heating element is thermally connected / in contact with the treatment unit 102, with its heat being conducted away through the treatment surface 1021.

[0035] Those skilled in the art will understand that in other embodiments, a temperature control system is also provided on the skin treatment device to ensure that the user can select an appropriate temperature according to individual needs and comfort, and to avoid safety issues caused by overheating. This system includes a temperature sensor and a controller that work together to monitor and regulate the temperature of the heating element.

[0036] In some embodiments, the light-emitting surface 1031 is spaced apart from the processing surface 1021 in a radial direction centered on the processing surface 1021.

[0037] In this design, the light-emitting surface 1031 is arranged on the circumference centered on the processing surface 1021, and there is a gap between the light-emitting surface 1031 and the processing surface 1021. This avoids the space constraints that would prevent the installation of a larger diameter light source due to their close proximity. Furthermore, it ensures that light rays adjacent to the processing unit on one side are not blocked by the processing unit.

[0038] like Figure 1 As shown, in a specific embodiment, the body portion 101 further includes a second end disposed opposite to the first end in its length direction, and the light-emitting portion 103 is located between the processing surface 1021 and the second end.

[0039] In this design, the main body 101 has a predetermined extension length, with a first end and a second end respectively disposed opposite to each other at both ends along its extension length. The processing unit 102 is located at the first end, and the light-emitting unit 103 is located between the processing unit 102 and the second end. That is, this design defines the positional relationship between the processing unit 102 and the light-emitting unit 103; specifically, the light-emitting unit 103 is disposed between the processing unit 102 and the second end of the main body 101. In other words, the light-emitting surface 1031 is also disposed between the processing surface 1021 and the second end of the main body 101. By disposing the light-emitting unit 103 at a certain position between the processing surface 1021 and the second end, this design ensures that there is sufficient space on the main body 101 to mount the light-emitting unit 103.

[0040] In this design, the ceramic sheet serves as the heating element in the fabrication of the skin treatment device, with its surface designated as the treatment surface 1021. The ceramic sheet is pre-welded to a circular cross-section at one end of an FPC (Flexible Printed Circuit) cable, while an NTC (Thermosensitive Ceramic Component) is welded to the other side of the circular cross-section for monitoring and controlling the heating temperature. The light-emitting element 103 includes a light guide structure and a light source, with the light source pre-welded to the FPC. During installation, the heating element is first assembled at the first end of the body 101, and then the FPC cable is systematically straightened along the length of the body 101 towards the second end. The light-emitting element 103 is installed at the middle of the cable extension, with the transparent light guide structure fixedly mounted on the lower housing, and the light source precisely embedded in a pre-set groove in the light guide structure via the FPC. Finally, a pressure plate assembly is used to press and fix the entire FPC to the lower housing, ensuring stable positioning of the ceramic sheet and the light-emitting element within the body 101.

[0041] like Figure 3 and Figure 6As shown, the surface of the light guide structure in this solution is the light-emitting surface 1031. Those skilled in the art will understand that in other embodiments, when the main body does not have a light guide structure, only the housing of the main body has an opening for mounting the light source in the light-emitting part; in this case, the side of the light source facing the environment constitutes the light-emitting surface 1031. That is to say, this solution does not specifically limit the form in which the light-emitting surface 1031 is arranged.

[0042] It is also worth noting that the shapes and mounting methods of the flexible printed circuit board, processing surface 1021, and light-emitting surface 1031 in the above scheme are all illustrative examples. That is to say, in other embodiments, the printed circuit board can be square or other shapes, and the processing surface 1021 and light-emitting surface 1031 can also be other shapes other than circular.

[0043] In one specific implementation, the distance between the light-emitting surface 1031 and the processing surface 1021 is no greater than 40 mm.

[0044] In this solution, the distance between the light-emitting surface 1031 and the treatment surface 1021 is set to no more than 40mm. This setting ensures that the distance between the light-emitting surface 1031 and the treatment surface 1021 is not too far. This provides sufficient illumination when the treatment surface is far from the affected area, and provides a positioning reference when the treatment surface is close to the affected area, enabling users to accurately locate the skin area to be treated in low-light environments and improving the user experience.

[0045] It is worth noting that the spacing between the light-emitting surface 1031 and the processing surface 1021 in this scheme refers to the straight-line distance between the center of the light-emitting surface 1031 and the center of the processing surface 1201 along the length direction of the body portion, i.e., the distance between the light-emitting surface 1031 and the processing surface 1201. Figure 3 The distance is indicated by H in the middle.

[0046] In some embodiments, the light-emitting surface 1031 is annular or arranged in annular order to completely or partially surround the processing part 102.

[0047] In this design, the arrangement of the light-emitting surface 1031 is not limited. For example, the light-emitting surface 1031 can be circular and positioned between the treatment surface 1021 and the second end. This design provides the user with a concentrated light source, helping to provide sufficient illumination when the treatment surface 1021 comes into contact with the skin. Alternatively, the light-emitting surface 1031 can be a series of spaced-apart circles, which can completely or partially surround the outer periphery of the treatment section 102. Another example is that the light-emitting surface 1031 can be a ring structure surrounding the outer periphery of the treatment section 102. This arrangement of the light-emitting surface 1031 surrounding the treatment surface 1021 provides a more uniform illumination effect, reduces shadows, and helps the user more accurately locate and treat the affected area. In other words, this design offers multiple possibilities for the arrangement of the light-emitting surface 1031 in the skin treatment device 100. This design flexibility allows the light-emitting surface 1031 to be optimally configured according to actual application requirements and the structural characteristics of the device.

[0048] In one specific embodiment, the body portion 101 has a preset thickness, and the body portion 101 has an upper surface and a lower surface facing opposite directions in its thickness direction, and the light-emitting portion 103 is disposed on the lower surface of the body portion 101.

[0049] In this design, the main body 101 of the skin treatment device 100 has a predetermined thickness. Along the thickness direction of the main body 101, two surfaces facing opposite directions are provided: an upper surface and a lower surface. The light-emitting part 103 is disposed on the lower surface. Specifically, one or more holes are specially formed on the lower housing of the main body 101. These holes are designed to allow light emitted from the light source of the light-emitting part 103 to pass through smoothly. The shapes of these light-transmitting holes precisely match the shape of the light source, ensuring that light can be efficiently and directionally transmitted from the light source, thereby illuminating the skin area requiring treatment.

[0050] In some embodiments, the skin treatment device 100 further includes at least one window 106, which is disposed at least in at least one direction / position in the circumferential direction centered on the treatment surface 1021.

[0051] In this design, since the processing surface 1021 and the light-emitting surface 1031 are located on the same side of the body portion 101, and the light-emitting surface 1031 is disposed on the lower surface of the body portion 101, the processing surface 1021 is also located on the lower surface of the body portion 101. Thus, during use, the user cannot observe the contact between the processing surface 1021 and the skin from the upper surface of the body portion 101. To address this issue, a viewing window 106 is specifically provided on the skin treatment device 100. Specifically, the body portion 101 of the skin treatment device 100 has at least one viewing window 106 at a first end, wherein the viewing window 106 extends in the thickness direction of the body portion 101 and penetrates both the upper and lower surfaces of the body portion 101. More specifically, the viewing window 106 is disposed in at least one direction or position circumferentially centered on the processing surface 1021. That is, this design does not specifically limit the number of viewing windows 106; there can be one or more. When a window 106 is provided, it is positioned in any direction around the processing surface 1021, centered on the processing surface 1021. For example, a single window 106 may be positioned along the length of the body portion 101 centered on the processing surface 1021, and extend away from the second end, i.e., attached to... Figure 1 The arrangement described herein. When multiple windows 106 are provided, they are arranged in any direction around the treatment surface 1021 of the treatment unit 102, centered on the treatment surface 1021. For example, when two windows 106 are provided (not shown in the figures), the two windows 106 can each extend along the width direction of the body portion 101. This design ensures that the user can observe the contact between the treatment surface 1021 and the target skin from different angles through the windows 106, thereby improving the accuracy and convenience of treatment.

[0052] like Figure 4 and Figure 5 As shown, in a specific embodiment, the first end includes a first structure 104 and a second structure 105, and a processing surface 1021 is disposed on the lower surface of the first structure 104; a hollow portion extending in the thickness direction of the body portion is provided between the first structure 104 and the second structure 105, and the hollow portion forms a viewing window 106.

[0053] In this design, only one viewing window 106 is provided on the main body 101. Specifically, the main body 101 has two structures at its first end: a first structure 104 and a second structure 105. Both structures extend along the length of the main body 101 from its first end toward the direction away from its second end, and the extension length of the first structure 104 is less than the extension length of the second structure 105. An arc-shaped cutout extending in the thickness direction of the main body is provided in the area between the first structure 104 and the second structure 105; this cutout is the viewing window 106.

[0054] It is worth noting that in this solution, the processing surface 1021 on the processing unit 102 is disposed on the lower surface of the first structure 104, and the light-emitting surface 1031 is disposed on the lower surface of the body unit 101.

[0055] It is also worth noting that the shape of the cutout described in the above scheme is merely exemplary and not restrictive. That is to say, in other schemes, the shape of the cutout can be any shape other than an arc.

[0056] In one specific embodiment, the first end includes a first structure 104 and a second structure 105 spaced apart along the length of the body portion, and a processing surface 1021 is disposed on the lower surface of the first structure 104; a window 106 made of transparent material is disposed between the first structure 104 and the second structure 105.

[0057] In this design, the main body 101 has two structures spaced apart along the length of the main body 101 at its first end: a first structure 104 and a second structure 105, wherein the extension length of the first structure 104 is less than the extension length of the second structure 105. A perforated portion extending in the thickness direction of the main body is provided between the first structure 104 and the second structure 105, and a viewing window 106 made of transparent material is provided at the location of the perforated portion. The transparent material can be a plate-like structure made of glass or plastic.

[0058] like Figure 3 As shown, in one specific embodiment, the lower surface of the first structure 104 protrudes beyond the lower surface of the second structure 105. That is, the processing surface 1021 protrudes beyond both the lower surface of the second structure 105 and the lower surface of the body portion 101. This arrangement offers several advantages. Specifically, during the operation positioning phase, the protruding lower surface of the second structure 105 facilitates the positioning of the processing surface 1021 towards the target skin area. Furthermore, when the processing surface 1021 contacts the skin, the single contact interface formed by the protruding structure significantly improves operational stability and enhances the user's perception accuracy of the processing pressure.

[0059] Those skilled in the art will understand that, in such cases Figure 3 In other embodiments shown, the lower surface of the first structure 104 protrudes from both the lower surface of the second structure 105 and the lower surface of the body portion 101. This arrangement avoids interference between the lower housing of the body portion 101 and the processing surface 1021, further optimizing the fit between the processing surface 1021 and the skin's curved surface, and improving the user experience.

[0060] It is worth noting that this solution does not limit the position between the processing surface 1021 and the lower surface of the body 101. That is, in a specific embodiment, the extension surface of the processing surface 1021 away from the second end and the lower surface of the body 101 form an angle between their extension surfaces away from the second end, and this angle is acute. In other words, the processing surface 1021 in this solution is not parallel to the lower surface of the body 101, but rather forms a specific acute angle structure with the light-emitting surface 1031, which is also located in the region far from the second end (as shown in the attached diagram). Figure 3 (As shown). In another specific embodiment, the processing surface 1021 is provided parallel to the lower surface of the body portion 101. That is, in this embodiment, the lower surface of the first structure 104 protrudes from both the lower surface of the second structure 105 and the lower surface of the body portion 101, and the processing surface 1021 is provided parallel to the lower surface of the body portion (not shown in the figure).

[0061] like Figure 3 As shown, in a specific embodiment, the second structure 105 has an end face 1051 disposed parallel to the thickness direction of the body portion 101 at a location away from the second end, and the height of the end face 1051 is lower than the height of the body portion 101; an upper inclined surface 1052 is disposed between the upper surface of the body portion 101 and the end face 1051, and / or a lower inclined surface 1053 is disposed between the lower surface of the body portion 101 and the end face 1051.

[0062] In this design, the extended end of the second structure 105 has an end face 1051. This end face 1051 is a plane that is opposite to the second end of the main body 101 and parallel to the thickness direction of the main body 101. The height of this plane is lower than the height of the main body. An upper inclined surface 1052 is formed between the upper surface of the main body 101 and the end face 1051 of the second structure 105, and a lower inclined surface 1053 is formed between the lower surface of the main body 101 and the end face 1051 of the second structure 105. In other words, the upper and lower surfaces of the second structure 105 in this design, which are opposite each other in the thickness direction, are not parallel to the upper or lower surface of the main body 101, but rather are inclined surfaces.

[0063] In this design, the second structure 105 is designed to be relatively thin, which offers several advantages. First, the thinner second structure 105 effectively avoids obstructing the user's view, allowing the user to more easily observe the contact between the treatment surface 1021 and the target skin through the viewing window 106 between the first structure 104 and the second structure 105. This design ensures that the user can accurately align the device with the affected area, thereby improving the accuracy and effectiveness of the treatment. Second, the thinner design of the second structure 105 makes it easier for the treatment surface 1021 to protrude from its underlying surface, thus making it easier for the treatment surface 1021 to contact the target skin. Furthermore, this design saves materials, as the thinner second structure 105 requires less material. This not only helps reduce resource consumption but also lowers the manufacturing cost of the device, making the product more competitive in the market.

[0064] It is worth noting that the extension direction of the height of the end face of the second structure 105 in this scheme refers to the extension direction of the thickness of the main body 101, i.e., the attached... Figure 3 The vertical extension direction in the middle.

[0065] Those skilled in the art will understand that, in other embodiments, only the upper surface of the second structure 105 may be configured as an upper inclined surface 1052, and the lower surface of the second structure 105 may be configured as a plane parallel to the lower surface of the body portion 101. Alternatively, only the lower surface of the second structure 105 may be configured as a lower inclined surface 1053, and the upper surface of the second structure 105 may be configured as a plane parallel to the upper surface of the body portion 101. Both of these embodiments fall within the scope of protection of this application.

[0066] Those skilled in the art will also understand that, in other embodiments, a chamfer is provided at the junction of the upper surface of the second structure 105 and its end face 1051, and simultaneously, a chamfer is also provided at the junction of the lower surface of the second structure 105 and its end face 1051. By providing chamfers at the junctions, sharp edges are eliminated, which not only prevents sharp edges from scratching users, but also makes the appearance of the device more streamlined and elegant.

[0067] In some implementations, user convenience and portability are taken into consideration; therefore, multiple control functions are integrated into the housing of the skin treatment device 100 in this solution. First, control buttons for turning the treatment unit 102 on or off are provided on the housing of the main body 101. These buttons allow users to directly operate the treatment unit 102 to start and stop it. Second, to ensure the safety and effectiveness of the treatment process, the device is also equipped with control buttons to adjust the temperature of the treatment surface 1021. Users can select a suitable temperature setting through these control buttons according to their individual needs and comfort to obtain the best treatment effect. Furthermore, considering the important role of the light-emitting unit 103 in providing illumination during treatment, this solution also provides dedicated buttons on the housing to control the turning of the light-emitting unit 103 on or off. In this way, users can flexibly control the lighting function according to ambient light conditions and personal preferences.

[0068] Those skilled in the art will also understand that, for the convenience of user operation, the aforementioned buttons can be located on the side of the body 101 away from the processing surface 1021, that is, on the housing at the upper surface of the body 101.

[0069] In some implementations, to improve the portability of the device, this solution also includes a carrying structure such as a lanyard 107. These structures not only make the device easy to carry and store, but also facilitate user use outdoors or while traveling, increasing the device's practicality.

[0070] In summary, the skin treatment device 100 of this solution achieves convenient operation, personalized treatment, and flexible use by setting multi-functional control buttons and carrying structure on the main body shell, thus meeting the treatment needs of users in different scenarios.

[0071] Example 2

[0072] like Figure 4 and Figure 5 As shown, this embodiment provides a skin treatment device 100, which includes a body portion 101 and a treatment portion disposed at a first end of the body portion 101 in the length direction. The treatment portion has a treatment surface 1021 for applying heat to the object being treated. The body portion has a predetermined thickness and includes an upper surface and a lower surface facing opposite directions in the thickness direction. The treatment portion is disposed on the lower surface. The skin treatment device also includes a viewing window 106 for observing the treatment surface through the viewing window from the upper surface. The viewing window 106 is disposed at least in at least one direction / position in the circumferential direction centered on the treatment surface 1021.

[0073] In one specific embodiment, the first end includes a first structure 104 and a second structure 105 spaced apart along the length of the body portion 101, and a processing surface 1021 is disposed on the lower surface of the first structure 104; a window 106 made of transparent material is disposed between the first structure 104 and the second structure 105.

[0074] In one specific embodiment, the extended end of the second structure 105 has an end face 1051 that is parallel to the thickness direction of the body portion 101, and the height of the end face 1051 is lower than the height of the body portion 101; an upper inclined surface 1052 is provided between the upper surface of the body portion 101 and the end face 1051, and / or a lower inclined surface 1053 is provided between the lower surface of the body portion 101 and the end face 1051.

[0075] In one specific embodiment, the main body 101 of the skin treatment device is further provided with a light-emitting part, which has a light-emitting surface 1031 for emitting light into the environment, and the light-emitting surface 1031 is spaced apart from the treatment surface 1021.

[0076] In the above embodiments, the relative height relationship between the treatment surface 1021 and the light-emitting surface 1031 is not limited, because the window itself can facilitate the user's line of sight to locate the relative position of the treatment surface 1021 and the affected area.

[0077] Those skilled in the art will understand that the first structure, the second structure, and the window in this embodiment are set in the same way as in embodiment one. Therefore, the accompanying drawings corresponding to the scheme in embodiment one are used to explain the content of this scheme.

[0078] While numerous embodiments of this application have been shown and described herein, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Many modifications, alterations, and alternatives will arise for those skilled in the art without departing from the spirit and intent of this application. It should be understood that various alternatives to the embodiments of this application described herein may be employed in the practice of this application. The appended claims are intended to define the scope of protection of this application and therefore cover equivalents or alternatives within the scope of these claims.
