Cosmetic pen

Abstract

This application provides a beauty pen, relating to the field of beauty device technology. The beauty pen includes a mounting base, a first elastic element, a bottom shell, and a pressing element. The first elastic element is disposed in a first region of the mounting base. The bottom shell is rotatably connected to the mounting base, and the pressing element passes through the bottom shell. The bottom shell is used to rotate relative to the mounting base to push the pressing element to move relative to the mounting base to either the first region or a second region. When the pressing element is in the first region, it abuts against the first elastic element. This application utilizes the rotatable connection between the bottom shell and the mounting base with the first elastic element, and the bottom shell's rotation to push the pressing element relative to the mounting base, allowing the pressing element to move between the first and second regions of the mounting base. Thus, the beauty pen can rotate the bottom shell as needed to move the pressing element to the first region to achieve elastic extension and contraction in conjunction with the first elastic element, or to a second region different from the first region, providing different pressing effects.

Description

Technical Field

[0001] This application relates to the field of beauty equipment technology, and in particular to a beauty pen. Background Technology

[0002] A beauty pen is a device that uses a flexible, retractable pressure point to massage the skin and achieve a beauty effect. In most beauty pens, the pressure point is in a fixed position, providing only a fixed pressure effect, which prevents the beauty pen from meeting certain usage needs. Utility Model Content

[0003] To solve the above-mentioned technical problems, this application provides a beauty pen, which includes:

[0004] The mounting base has different first and second areas;

[0005] The first elastic element is located in the first region;

[0006] The base shell is rotatably connected to the mounting base and is used to rotate relative to the mounting base in a preset direction; and

[0007] The pressing member is inserted into the bottom shell and fixed relative to the bottom shell in a preset direction. The bottom shell is used to rotate relative to the mounting base to push the pressing member to move relative to the mounting base to the first area or the second area. When the pressing member is in the first area, the pressing member abuts against the first elastic member and is used to achieve elastic extension and contraction relative to the mounting base under the action of the first elastic member.

[0008] In some embodiments, the beauty pen includes a positioning member disposed on one of a bottom shell and a mounting base, and the other of the bottom shell and the mounting base is provided with a first positioning groove and a second positioning groove spaced apart from each other; when the pressing member is in a first region, the positioning member is in the first positioning groove; when the pressing member is in a second region, the positioning member is in the second positioning groove.

[0009] In some embodiments, an assembly groove is provided on one of the bottom shell and the mounting base, and a positioning member is disposed in the assembly groove; when the pressing member is in the first region, the first positioning groove is disposed opposite to the assembly groove, and one end of the positioning member away from the bottom wall of the assembly groove is disposed in the first positioning groove; when the pressing member is in the second region, the second positioning groove is disposed opposite to the assembly groove, and one end of the positioning member away from the bottom wall of the assembly groove is disposed in the second positioning groove.

[0010] In some embodiments, one end of the positioning member abuts against the bottom wall of the assembly groove. The positioning member is a flexible body and has a cavity formed inside.

[0011] In some embodiments, the beauty pen includes a reset member disposed in an assembly groove, the reset member being disposed between the bottom wall of the assembly groove and a positioning member, and the two ends of the reset member abutting against the bottom wall of the assembly groove and the positioning member, respectively.

[0012] In some embodiments, a mounting groove is provided at one end of the bottom shell near the mounting base, and the bottom shell is fitted onto the bottom end of the mounting base through the mounting groove. The bottom wall of the mounting groove is disposed opposite to the bottom wall of the mounting base. The first region and the second region are two regions of the bottom wall of the mounting base. The bottom shell has a through hole that extends to the bottom wall of the mounting groove, and the pressing member passes through the through hole into the bottom shell. The bottom wall of the mounting base and the bottom wall of the mounting groove are provided with a positioning member, and the other is provided with a first positioning groove and a second positioning groove.

[0013] In some embodiments, the bottom wall of the mounting base is provided with a first telescopic groove, the first telescopic groove is located in a first region, a first elastic member is disposed in the first telescopic groove, the pressing member is columnar, and the axial direction of the pressing member is parallel to the depth direction of the first telescopic groove; the mounting base also includes a support portion, which is located in a second region and is part of the bottom wall of the mounting base, and when the pressing member is in the second region, the pressing member abuts against the support portion.

[0014] In some embodiments, the preset direction includes a clockwise direction and a counterclockwise direction. The pressing member is used to move from the first region to the second region in a clockwise direction or from the second region to the first region in a counterclockwise direction under the push of the bottom shell. The bottom shell is provided with a first limiting part, and the mounting base is provided with a second limiting part. When the pressing member is in the first region or the second region, the first limiting part and the second limiting part contact and limit each other.

[0015] In some embodiments, one of the first limiting part and the second limiting part is a protrusion and the other is a track, the track extends in a preset direction, and the protrusion is located in the track; when the pressing member is in the first region, one end of the track abuts against the protrusion to prevent the bottom shell from moving further relative to the mounting seat in a counterclockwise direction; when the pressing member is in the second region, the other end of the track abuts against the protrusion to prevent the bottom shell from moving further relative to the mounting seat in a clockwise direction.

[0016] In some embodiments, a first annular groove is provided on the bottom shell, and a second annular groove is provided on the mounting base. The first annular groove and the second annular groove are disposed opposite to each other. The beauty pen also includes a slider disposed in the first annular groove and the second annular groove to reduce the rotational resistance between the bottom shell and the mounting base. The slider is a metal body and is arc-shaped. The slider covers more than half of the bottom wall of the first annular groove and more than half of the bottom wall of the second annular groove.

[0017] In some embodiments, the beauty pen also includes a power supply component electrically connected to the pressing element for outputting a microcurrent through the pressing element.

[0018] The beneficial effects of the beauty pen provided in this application are:

[0019] This application rotatably connects the bottom shell to the mounting base equipped with a first elastic element. When the bottom shell rotates, it pushes the pressing element to move relative to the mounting base, allowing the pressing element to move between a first region and a second region of the mounting base. Thus, the beauty pen can rotate the bottom shell as needed to move the pressing element to the first region to cooperate with the first elastic element to achieve elastic extension and contraction, or to the second region, which is different from the first region, to provide different pressing effects. This is beneficial for diversifying the pressing effects of the beauty pen and expanding the range of needs that the beauty pen can meet. Attached Figure Description

[0044] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0045] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0046] This application provides a beauty pen for achieving cosmetic effects through skin massage. Please refer to... Figure 1 and Figure 2 , Figure 1 This is a three-dimensional structural diagram of a beauty pen provided in some embodiments of this application. Figure 2 yes Figure 1 A cross-sectional structural diagram of the beauty pen in the embodiment.

[0047] The beauty pen 10 includes a pressing component 11 for pressing against human skin. The pressing component 11 can form one end of the beauty pen 10, for example... Figure 2 As shown, the bottom portion of the beauty pen 10 can be formed by the pressing component 11.

[0048] In some embodiments, the pressing assembly 11 may include a pressing member 100, a first elastic member 110, and a mounting base 120. The pressing member 100 may be movably disposed on the mounting base 120. The first elastic member 110 may be disposed on the mounting base 120. The pressing member 100 may elastically extend and retract relative to the mounting base 120 through the first elastic member 110, so that the beauty pen 10 can massage the skin through the elastically extendable pressing member 100.

[0049] The pressing element 100 can be cylindrical, with its axis parallel to the axis of the beauty pen 10. In other embodiments, the pressing element 100 can also be designed in other shapes, such as a block shape, as needed. Other structures of the beauty pen 10 will be described in detail below. The pressing element 100 can be made of gold-plated material to prevent discomfort for users allergic to metals such as stainless steel.

[0050] Optionally, the beauty pen 10 has a first state and a second state. The beauty pen 10 is configured to provide different pressing pressures in different states. Please refer to [link / reference]. Figures 1 to 3 , Figure 3 This is an exploded structural diagram of a beauty pen provided in some embodiments of this application.

[0051] The pressing member 100, which is movably disposed on the mounting base 120, is movable relative to the mounting base 120 and is used to move relative to the mounting base 120 in a preset direction X, so that the beauty pen 10 switches to a first state or a second state. The pressing component 11 may include a first elastic member 110 and a second elastic member 130, both of which are disposed on the mounting base 120 but in different positions.

[0052] In the first state, the pressing member 100 abuts against the first elastic member 110, and the pressing member 100 is used to elastically extend and retract relative to the mounting base 120 under the action of the first elastic member 110. In the second state, the pressing member 100 abuts against the second elastic member 130, and the pressing member 100 is used to elastically extend and retract relative to the mounting base 120 under the action of the second elastic member 130. In use, the pressing member 100 can move relative to the mounting base 120 to the position of the first elastic member 110 under the action of external force, so that the beauty pen 10 switches to the first state, or move relative to the mounting base 120 to the position of the second elastic member 130, so that the beauty pen 10 switches to the second state. This external force is usually provided by the user during use.

[0053] The first elastic element 110 and the second elastic element 130 have different elastic coefficients. Understandably, the elastic coefficient represents the magnitude of the elastic force generated by the elastic element when it undergoes a unit deformation. The larger the elastic coefficient of the elastic element, the greater the force required to achieve a unit deformation, and the more difficult it is to press. In this embodiment, both the first elastic element 110 and the second elastic element 130 can be springs. In other embodiments, the first elastic element 110 and the second elastic element 130 can also be other devices capable of providing elastic force. The following description mainly uses the example where both the first elastic element 110 and the second elastic element 130 are springs.

[0054] Therefore, the pressing force provided by the beauty pen 10 in the first state is different from the pressing force provided by the beauty pen 10 in the second state. Taking the elastic coefficient of the first elastic element 110 being greater than that of the second elastic element 130 as an example, the beauty pen 10 can provide a greater pressing force in the first state compared to its second state. The following explanation will mainly use this example.

[0055] This embodiment of the application provides a first elastic element 110 and a second elastic element 130 with different elastic coefficients on the mounting base 120, and movably mounts the pressing element 100 on the mounting base 120. This allows the pressing element 100 to move relative to the mounting base 120 to a position that abuts against the first elastic element 110 or against the second elastic element 130. Thus, under the action of elastic elements with different elastic coefficients, elastic extension and contraction relative to the mounting base 120 can be achieved. Therefore, the beauty pen 10 can adjust the pressing force provided by the pressing element 100 according to different usage needs by adjusting the relative position of the pressing element 100 and the mounting base 120, which is beneficial to improving the applicability of the beauty pen 10.

[0056] The beauty pen 10 has two modes: a first mode for massaging sensitive areas of the body, such as the cheeks, around the eyes, mouth, and top of the head; and a second mode for massaging areas used in daily training, such as the back of the head, temples, neck, and hands. For example, the beauty pen 10 can be used to massage the skin on the hands and face. Since facial skin is generally more sensitive than hand skin, the beauty pen 10 can be in its first mode, providing relatively high pressure, when massaging the hands; and in its second mode, providing relatively low pressure, when massaging the face.

[0057] Through the above design, the beauty pen 10 provided in this embodiment is applicable to more scenarios and has superior applicability compared to other beauty devices with similar functions but only able to provide fixed pressing pressure.

[0058] Furthermore, the beauty pen 10 provided in this application embodiment is also compact. Generally speaking, when a human hand or conventional massage device massages the human body, it is difficult to accurately press the creases and tiny muscle areas. The beauty pen 10 provided in this application embodiment uses an elastically retractable pressing element 100 to massage the human body, which can train the deep stiff areas of the human body's muscles and help improve the beauty effect.

[0059] It should be noted that the beauty pen 10 provided in this application embodiment may, but is not limited to, having a first state and a second state. Specifically, in some embodiments, the beauty pen 10 only has two states corresponding to different pressing pressures: the first state and the second state. In other embodiments, the beauty pen 10 has not only a first state and a second state, but also more states, and can provide different pressing pressures in different states. For example, the beauty pen 10 may include two or more elastic elements, such as, but not limited to, 3, 4, 5, etc., with different elastic coefficients for each elastic element. The pressing element 100 can move relative to the mounting base 120 to contact one of the elastic elements under the user's adjustment, so that the beauty pen 10 can provide the pressing pressure required by the user. In other embodiments, the number of elastic elements used by the beauty pen 10 to cooperate with the pressing element 100 to provide pressing pressure may also be one. The following mainly uses two such elastic elements as an example for explanation.

[0060] It should be understood that the terminology used in this specification and appended claims is for the purpose of describing particular embodiments only and is not intended to limit the application. As used in this specification and appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise. Similarly, the terms “first” and “second” in the description of this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include one or more of the stated features. Furthermore, the term “multiple” in the description of this application means two or more, unless otherwise explicitly specified.

[0061] In some embodiments, the pressing assembly 11 may include a bottom shell 140, with the pressing member 100 passing through the bottom shell 140 and fixed relative to the bottom shell 140 in a preset direction X. The bottom shell 140 is rotatably connected to the mounting base 120 and is used to rotate relative to the mounting base 120 to push the pressing member 100 to move relative to the mounting base 120, thereby switching the beauty pen 10 to a first state or a second state.

[0062] The preset direction X is the direction in which the base shell 140 rotates relative to the mounting base 120. This direction can be, but is not limited to, the circumferential direction of the beauty pen 10, and will be used as an example in the following description. It can be understood that the preset direction X includes two opposite directions, corresponding to clockwise and counterclockwise rotation. In other embodiments, the preset direction X can also be other directions, such as a straight line perpendicular to the axis of the beauty pen 10.

[0063] The bottom shell 140 can form part of the outer surface of the beauty pen 10 and cover the mounting base 120, so that the user can adjust the position of the pressing member 100 by rotating the bottom shell 140. In other embodiments, the pressing member 100 can also be moved relative to the mounting base 120 by direct operation by the user, so that the beauty pen 10 does not need to have a bottom shell 140. The following description mainly uses the beauty pen 10 including the bottom shell 140 as an example.

[0064] Please see Figures 3 to 5 , Figure 4 This is a three-dimensional structural diagram of a beauty pen in its first state, provided in some embodiments of this application. Figure 5 yes Figure 4 The diagram shown is a three-dimensional structural illustration of a portion of the beauty pen in its second state. For ease of understanding, Figure 4 and Figure 5 The diagram shows the structure of the beauty pen 10 with the bottom shell 140 removed.

[0065] In some embodiments, the preset direction X includes a clockwise direction X1 and a counterclockwise direction X2, corresponding to the direction of clockwise rotation of the bottom shell 140 and the direction of counterclockwise rotation of the bottom shell 140. The clockwise direction X1 and the counterclockwise direction X2 are... Figure 2 The beauty pen 10 shown is viewed from a low angle, i.e. Figures 3 to 5 The perspective shown will be used as an example for explanation below. It can be understood that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly, but it does not mean that the product structure changes.

[0066] like Figure 4 As shown, in the first state, the pressing member 100 is positioned where the first elastic member 110 is located. At this time, the pressing member 100 abuts against the first elastic member 110, and is used to elastically extend and retract relative to the mounting base 120 along the axial direction of the beauty pen 10 under the action of the first elastic member 110. The bottom shell 140 can be rotated counterclockwise X2 relative to the mounting base 120 under user adjustment to push the pressing member 100 to... Figure 5 The position shown allows the beauty pen 10 to switch from the first state to the second state.

[0067] like Figure 5 As shown, in the second state, the pressing member 100 is positioned where the second elastic member 130 is located. At this time, the pressing member 100 abuts against the second elastic member 130, and is used to elastically extend and retract relative to the mounting base 120 along the axial direction of the beauty pen 10 under the action of the second elastic member 130. Similarly, the bottom shell 140 can be rotated clockwise X1 relative to the mounting base 120 under user adjustment to push the pressing member 100 to... Figure 4 The position shown allows the beauty pen 10 to switch from the second state to the first state.

[0068] In some embodiments, a first telescopic groove 101 and a second telescopic groove 102 spaced apart are provided on one side of the mounting base 120. A first elastic member 110 is disposed in the first telescopic groove 101, and a second elastic member 130 is disposed in the second telescopic groove 102. The pressing member 100 may be columnar, and the axial direction of the pressing member 100, the depth direction of the first telescopic groove 101, and the depth direction of the second telescopic groove 102 are parallel.

[0069] In this embodiment, the openings of the first telescopic groove 101 and the second telescopic groove 102 are adapted to the end of the pressing member 100 near the mounting base 120, so that this end of the pressing member 100 can extend into the first telescopic groove 101 or the second telescopic groove 102 under the action of external force. Taking the pressing member 100 as a cylinder as an example, the openings of the first telescopic groove 101 and the second telescopic groove 102 can both be circular holes, and their diameter can be slightly larger than the outer diameter of the pressing member 100. Thus, in the first state, when the pressing member 100 presses the human skin, its end near the mounting base 120 can extend into the first telescopic groove 101, and the same applies in the second state. In other embodiments, the pressing member 100 can also be a main body of other shapes, such as a prism, an irregularly shaped main body, etc., and the shapes of the first telescopic groove 101 and the second telescopic groove 102 correspond to the shapes of the pressing member 100.

[0070] In other embodiments, the first elastic element 110 and the second elastic element 130 can also be disposed on the bottom surface of the mounting base 120, thus eliminating the need for the first telescopic groove 101 and the second telescopic groove 102 in the beauty pen 10. In this embodiment, by disposing each elastic element within its corresponding telescopic groove, the groove wall can be used to restrict the displacement of the elastic element, and the telescopic groove can also accommodate part of the pressing member 100 when it is pressed, thereby limiting the movement trajectory of the pressing member 100. This ensures that the pressing member 100 and each elastic element remain stably in their corresponding positions even after multiple presses.

[0071] In this embodiment, both the first telescopic groove 101 and the second telescopic groove 102 can be grooves provided on the bottom surface of the mounting base 120. This allows the beauty pen 10 to utilize the internal space of the mounting base 120 to accommodate various elastic components and part of the pressing components 100, thereby improving the internal space utilization rate of the beauty pen 10 and achieving miniaturization. It should be noted that the beauty pen 10 provided in this embodiment... Figure 2 As shown, its bottom end is used as the pressing end, and the bottom portion of the beauty pen 10 is formed by the pressing component 11. In other embodiments, the beauty pen 10 may include two pressing components 11, which may respectively form the bottom portion and the top portion of the beauty pen 10.

[0072] Figure 4 and Figure 5 The diagram shows the structure of the beauty pen 10 when the pressing element 100 is subjected to external pressure. For example... Figure 4 As shown, in the first state, the tip of the pressing member 100 can extend into the opening of the first telescopic groove 101 under the action of pressing pressure. When the pressing member 100 is subjected to further external pressing pressure, the pressing member 100 can extend further into the first telescopic groove 101 and apply greater pressure to the first elastic member 110 to cause it to undergo elastic deformation.

[0073] When the pressing force on the pressing member 100 is removed, the first elastic member 110 returns to its original shape, and simultaneously applies an elastic restoring force to the pressing member 100, causing the pressing member 100 to move out of the first telescopic groove 101 along the axial direction of the beauty pen 10. After the pressing force is released, the user can change the position of the pressing member 100 by rotating the bottom shell 140, thereby adjusting the state of the beauty pen 10. Figure 5 As shown, in the second state, the top end of the pressing member 100 can extend into the opening of the second telescopic groove 102 under the action of pressing force. When the pressing member 100 is subjected to a further increase in external pressing force, the pressing member 100 can extend further into the second telescopic groove 102 and apply greater pressure to the second elastic member 130 so that it undergoes elastic deformation.

[0074] Optionally, the beauty pen 10 has a first state, a second state, and a third state. See also... Figures 3 to 6 , Figure 6 yes Figure 4 The diagram shown illustrates the three-dimensional structure of a portion of the beauty pen in its second state. Similarly, Figure 6 The diagram also shows the structure of the beauty pen 10 with the bottom shell 140 removed.

[0075] The third state is a state that is different from the first and second states. The corresponding usage scenario is that when the pressing part 100 is subjected to pressing force, the pressing part 100 will not elastically stretch or contract.

[0076] In some embodiments, the mounting base 120 further includes a support portion 121, which, along with the first elastic member 110 and the second elastic member 130, is located on the same side of the mounting base 120, but at different positions. In the third state, the pressing member 100 abuts against the support portion 121, so that the pressing member 100 does not elastically expand or contract when subjected to pressing force. The pressing member 100 can also be used to move relative to the mounting base 120 in a preset direction X, so that the beauty pen 10 switches to the third state.

[0077] The support portion 121 supports the pressing member 100 in the third state, and its specific structure can be set according to actual conditions. In this embodiment, the support portion 121 is part of the bottom wall of the mounting base 120. The first telescopic groove 101 and the second telescopic groove 102 are both grooves on the bottom wall surface of the mounting base 120. The pressing member 100 can move relative to the mounting base 120 on the bottom side. When the pressing member 100 moves to the position of the first telescopic groove 101, the pressing member 100 will extend into the first telescopic groove 101 and abut against the first elastic member 110 when it is pressed; when the pressing member 100 moves to the position of the second telescopic groove 102, the pressing member 100 will extend into the second telescopic groove 102 and abut against the second elastic member 130 when it is pressed. When the pressing member 100 moves to the position of the support portion 121, the pressing member 100 will abut against the support portion 121 and will not elastically extend or retract when it is pressed.

[0078] In other embodiments, the support portion 121 may also be other structures, such as a protrusion on the bottom surface of the mounting base 120, or a component provided on the bottom surface of the mounting base 120. The following description mainly takes the support portion 121 as part of the bottom wall of the mounting base 120 as an example.

[0079] The support portion 121 can be positioned between the first elastic member 110 and the second elastic member 130 along a preset direction X. During the rotation of the base shell 140 relative to the mounting base 120, the beauty pen 10 can sequentially switch between a first state, a third state, and a second state. In other embodiments, the relative positions of the support portion 121, the first elastic member 110, and the second elastic member 130 can also be designed differently; for example, the first elastic member 110, the second elastic member 130, and the support portion 121 can be arranged sequentially along a preset direction X.

[0080] In other embodiments, the pressing member 100 may also be configured to switch only between the positions of the various elastic members, so that the beauty pen 10 does not need to be provided with a support portion 121.

[0081] Please see Figure 3 and Figure 7 , Figure 7 This is an exploded structural diagram of a portion of the pressing component provided in some embodiments of this application.

[0082] In some embodiments, the beauty pen 10 may include a slider 150, which is disposed between the bottom shell 140 and the mounting base 120 and contacts the bottom shell 140 and the mounting base 120 respectively, in order to reduce the rotational resistance of the bottom shell 140 and the mounting base 120.

[0083] The bottom shell 140 may be provided with a first annular groove 103, and the mounting base 120 may be provided with a second annular groove 104, with the first annular groove 103 and the second annular groove 104 being arranged opposite to each other. The sliding member 150 may be disposed within the first annular groove 103 and the second annular groove 104.

[0084] Optionally, the bottom shell 140 is fitted onto the mounting base 120 and forms the bottom outer surface of the beauty pen 10. The first annular groove 103 can be disposed on the inner sidewall of the bottom shell 140, and the second annular groove 104 can be disposed on the outer sidewall of the mounting base 120. The sliding member 150 is located within the first annular groove 103 and the second annular groove 104. This will be used as an example in the following description. In other embodiments, the first annular groove 103 and the second annular groove 104 can also be disposed in other locations; for example, the first annular groove 103 can be disposed on the top surface of the bottom shell 140, and the second annular groove 104 can be disposed on the bottom surface of the mounting base 120.

[0085] The slider 150 is a metal body and is arc-shaped to facilitate installation or removal. In some embodiments, the slider 150 may cover more than half of the bottom wall of the first annular groove 103 and more than half of the bottom wall of the second annular groove 104. The slider 150 may be fitted onto the mounting base 120. During installation or removal, the slider 150 can undergo recoverable deformation under external force. In other embodiments, the slider 150 is not limited to the above structure. For example, the slider 150 may be an arc-shaped metal body that covers less than half of the bottom wall of the first annular groove 103 and the second annular groove 104; or the slider 150 may be annular, and its material may be, for example, metal or plastic.

[0086] This embodiment, by providing a sliding member 150 between the base shell 140 and the mounting base 120, not only reduces the rotational resistance between the base shell 140 and the mounting base 120, but also improves the rotational stability between them, preventing the cosmetic pen 10 from exhibiting fluctuating rotational resistance of the base shell 140. It should be noted that preventing a certain phenomenon mentioned herein does not mean completely eliminating its occurrence, but rather reducing its likelihood.

[0087] It should be understood that the terms "comprising" and "having," and any variations thereof, used in this application and the appended claims, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0088] Please refer to the above text. Figures 8 to 11 , Figure 8 This is an exploded structural diagram of some of the pressing components provided in some embodiments of this application. Figure 9 yes Figure 8 A three-dimensional structural diagram of some of the pressing components in the first state in the embodiment. Figure 10 yes Figure 8 A three-dimensional structural diagram of part of the pressing component in the second state in the embodiment. Figure 11 yes Figure 8 A three-dimensional structural diagram of a portion of the pressing component in the third state in the embodiment.

[0089] In some embodiments, the bottom shell 140 may be provided with a first limiting part 141, and the mounting base 120 may be provided with a second limiting part 122. The first limiting part 141 and the second limiting part 122 are used to contact and limit in the first state and the second state, so that the user can accurately rotate the bottom shell 140 to the position corresponding to the first state or the second state.

[0090] In this configuration, one of the first limiting portion 141 and the second limiting portion 122 can be a protrusion, and the other can be a track. The track extends along a predetermined direction X, and the protrusion is located within the track. In a first state, one end of the track abuts against the protrusion to prevent the bottom shell 140 from rotating further relative to the mounting base 120 in a clockwise direction X1. In a second state, the other end of the track abuts against the protrusion to prevent the bottom shell 140 from rotating further relative to the mounting base 120 in a counterclockwise direction X2.

[0091] When the bottom shell 140 is rotated clockwise X1 relative to the mounting base 120 until the pressing member 100 is in the position of the first elastic member 110, the beauty pen 10 switches to the first state. At this time, the first limiting part 141 and the second limiting part 122 contact and limit each other to prevent the bottom shell 140 from rotating further clockwise X1 relative to the mounting base 120. Thus, when the user rotates the bottom shell 140 clockwise X1 until it can no longer rotate, the user will know that the beauty pen 10 has switched to the first state.

[0092] When the bottom shell 140 rotates counterclockwise X2 relative to the mounting base 120 until the pressing member 100 is in the position of the second elastic member 130, the beauty pen 10 switches to the second state. At this time, the first limiting part 141 and the second limiting part 122 contact and limit each other to prevent the bottom shell 140 from rotating further counterclockwise X2 relative to the mounting base 120. Thus, when the user rotates the bottom shell 140 counterclockwise X2 until it can no longer rotate, the user will know that the beauty pen 10 has switched to the second state.

[0093] For ease of explanation, the following description will primarily use the example of the first limiting part 141 being a protrusion and the second limiting part 122 being a track. Figure 3 and Figure 8As shown, the first limiting part 141 can be a protrusion provided on the inner wall of the bottom shell 140, and the second limiting part 122 can be a track provided on the outer wall of the mounting base 120.

[0094] The specific structure of the second limiting part 122 can be designed according to requirements. For example... Figure 3 As shown, the second limiting part 122 can be an arc-shaped groove recessed into the outer wall of the mounting base 120. This arc-shaped groove extends along a predetermined direction X to form a track. The first limiting part 141 is disposed in the arc-shaped groove, and the two end walls of the arc-shaped groove along the predetermined direction X are respectively used to contact and limit the first limiting part 141 in a first state and a second state. The second limiting part 122 can be completely disposed on the side wall of the mounting base 120, or completely disposed on the bottom wall of the mounting base 120, or as shown in the diagram. Figure 3 As shown, it is installed on the side wall and bottom wall of the mounting base 120.

[0095] In other embodiments, the second limiting portion 122 can also be other track structures. For example, the outer wall of the mounting base 120 may have two spaced-apart protrusions, and the track is formed by these two protrusions. The two protrusions are respectively used to contact and limit the first limiting portion 141 in the first state and the second state. Alternatively, the outer wall of the mounting base 120 may have one protrusion, with the space on both sides of this protrusion along a preset direction X serving as the track. The opposite sides of this protrusion along the preset direction X are respectively used to contact and limit the first limiting portion 141 in the first state and the second state.

[0096] In other embodiments, the first limiting part 141 and the second limiting part 122 can also be other structures that can achieve the limiting function, and are not limited to one being a protrusion and the other being a track. For example, the first limiting part 141 and the second limiting part 122 can both be arc-shaped toothed surfaces extending along a preset direction X. During the process of the beauty pen 10 switching from the first state to the second state, the first limiting part 141 and the second limiting part 122 move relative to each other in an engaging manner. When the beauty pen 10 switches to the first state or the second state, the first limiting part 141 and the second limiting part 122 achieve limiting by contacting the edge of the toothed surface.

[0097] Optionally, a mounting groove 105 is provided at one end of the bottom shell 140 near the mounting base 120, and the bottom shell 140 is fitted onto the bottom end of the mounting base 120 through the mounting groove 105. The bottom wall of the mounting groove 105 can be disposed opposite to the bottom wall of the mounting base 120. Understandably, in this embodiment, the end where the bottom shell 140 is located is considered the bottom end of the beauty pen 10, and the mounting groove 105 is located at the top of the bottom shell 140. The bottom shell 140 has a through hole 106 extending to the bottom wall of the mounting groove 105, and the pressing member 100 passes through the through hole 106 into the bottom shell 140. This will be the primary example described below. In other embodiments, the bottom shell 140 does not need to have a mounting groove 105.

[0098] The first limiting part 141 can be completely disposed on the bottom wall of the mounting groove 105, and correspondingly, the second limiting part 122 is completely disposed on the bottom wall of the mounting base 120. The first limiting part 141 can also be completely disposed on the side wall of the mounting groove 105, and correspondingly, the second limiting part 122 is completely disposed on the side wall of the mounting base 120. The first limiting part 141 can also be... Figure 8 As shown, it is disposed on the bottom wall and side wall of the mounting groove 105, that is, at the connection between the bottom wall and side wall of the mounting groove 105. Correspondingly, the second limiting part 122 is as follows: Figure 3 As shown, it is installed on the side wall and bottom wall of the mounting base 120.

[0099] In some embodiments, the beauty pen 10 may further include a positioning member 160, which is disposed on one of the bottom shell 140 and the mounting base 120. The other of the bottom shell 140 and the mounting base 120 is provided with a first positioning groove 107 and a second positioning groove 108 spaced apart from each other. In a first state, the positioning member 160 is located in the first positioning groove 107. In a second state, the positioning member 160 is located in the second positioning groove 108.

[0100] During the transition from the first state to the second state of the beauty pen 10, the positioning member 160 moves with the relative rotation of the bottom shell 140 and the mounting base 120. The movement trajectory of the positioning member 160 during this movement extends along a preset direction X. The first positioning groove 107 and the second positioning groove 108 are both located on this movement trajectory of the positioning member 160. The first positioning groove 107 and the second positioning groove 108 can be arranged along the preset direction X.

[0101] During the transition from the first state to the second state of the beauty pen 10, the positioning member 160 is outside the first positioning groove 107 and the second positioning groove 108, and the positioning member 160 moves relative to the first positioning groove 107 and the second positioning groove 108. When the beauty pen 10 switches to the first state, the positioning member 160 enters the first positioning groove 107, thereby forming a limiting engagement with the groove wall of the first positioning groove 107, providing a certain resistance to the relative rotation of the bottom shell 140 and the mounting base 120, and preventing the bottom shell 140 from rotating relative to the mounting base 120 when no one is operating it. Similarly, when the beauty pen 10 switches to the second state, the positioning member 160 enters the second positioning groove 108, thereby forming a limiting engagement with the groove wall of the second positioning groove 108.

[0102] Optionally, the positioning element 160 is disposed on one of the bottom wall of the mounting groove 105 and the bottom wall of the mounting base 120, and the first positioning groove 107 and the second positioning groove 108 are disposed on the other one. This allows the beauty pen 10 to utilize the space along the axial direction of the bottom shell 140 and the mounting base 120 to arrange the positioning element 160, the first positioning groove 107, and the second positioning groove 108, thereby improving the utilization rate of the internal space of the beauty pen 10. In other embodiments, the positioning element 160 may also be disposed on one of the side wall of the mounting groove 105 and the side wall of the mounting base 120, with each positioning groove correspondingly disposed on the other one.

[0103] Understandably, this embodiment takes the beauty pen 10 having a first state and a second state as an example. Correspondingly, the bottom shell 140 or the mounting base 120 is provided with a first positioning groove 107 and a second positioning groove 108. When the beauty pen 10 has more than two states, the number of positioning grooves can also be more than two.

[0104] Optionally, one of the base shell 140 and the mounting base 120 is provided with an assembly groove 109, and the positioning member 160 is disposed in the assembly groove 109. In a first state, the first positioning groove 107 is disposed opposite to the assembly groove 109, and the end of the positioning member 160 away from the bottom wall of the assembly groove 109 is located in the first positioning groove 107. In a second state, the second positioning groove 108 is disposed opposite to the assembly groove 109, and the end of the positioning member 160 away from the bottom wall of the assembly groove 109 is located in the second positioning groove 108. The following description mainly uses this as an example. In other embodiments, the beauty pen 10 may not have an assembly groove 109, and the positioning member 160 may be disposed on the base shell 140 or the mounting base 120 in other ways.

[0105] The following description mainly uses the example of positioning element 160 being located on mounting base 120, and first positioning groove 107 and second positioning groove 108 being located on bottom shell 140.

[0106] Please see Figure 2 , Figure 8 and Figure 12 , Figure 12 yes Figure 2 The diagram shows a partial cross-sectional structure of the beauty pen.

[0107] In some embodiments, the pressing member 100 is cylindrical, and a first stop portion 111 is formed at the end of the pressing member 100 near the mounting base 120. A second stop portion 112 is provided at the end of the through hole 106 near the mounting base 120. The first stop portion 111 and the second stop portion 112 are adapted to each other. When the pressing member 100 is not subjected to pressing force, the first stop portion 111 is located in the second stop portion 112, and cooperates with the second stop portion 112 to achieve a stopping effect that prevents the pressing member 100 from disengaging from the end of the through hole 106 away from the mounting base 120 from the bottom shell 140.

[0108] The first stop portion 111 can be the end of the pressing member 100, and relative to other parts of the pressing member 100, the first stop portion 111 has a larger size in a direction perpendicular to the axial direction of the beauty pen 10. The second stop portion 112 can be a groove provided on one end wall of the through hole 106, and the groove wall can abut against the first stop portion 111 to prevent the first stop portion 111 from moving to other parts of the through hole 106.

[0109] Please continue reading. Figure 8 and Figure 12 In some embodiments, the positioning member 160 can be a flexible body, such as silicone or soft rubber. During the process of the beauty pen 10 switching from the first state to the second state, the positioning member 160 will be deformed by the pressure of the bottom shell 140. When the beauty pen 10 switches to the first state, the positioning member 160 will enter the first positioning groove 107. At this time, the deformed part of the positioning member 160 will use the first positioning groove 107 as a receiving space, the shape of the positioning member 160 will be restored, and the positioning member 160 will form a limiting fit with the first positioning groove 107. When the beauty pen 10 switches to the second state, the fit between the positioning member 160 and the second positioning groove 108 is similar and will not be described in detail.

[0110] Optionally, in both the first and second states, the positioning member 160 is partially housed within the assembly groove 109, with the end of the positioning member 160 furthest from the bottom wall of the assembly groove 109 positioned within the corresponding positioning groove. During the transition of the beauty pen 10 from the first state to the second state, the positioning member 160 is compressed and becomes fully positioned within the assembly groove 109.

[0111] When the positioning element 160 enters the first positioning groove 107 or the second positioning groove 108 and its shape is restored, the positioning element 160 can collide with the corresponding groove wall, thereby making a sound. This sound can serve as a prompt, indicating to the user that the bottom shell 140 has been rotated into place.

[0112] Optionally, a cavity 161 is formed inside the positioning member 160 to facilitate deformation of the positioning member 160. Along the axial direction of the beauty pen 10, in some embodiments, the cavity 161 is formed by the sidewalls and top wall of the positioning member 160; in other embodiments, the cavity 161 is formed by the sidewalls of the positioning member 160 and extends to the top surface of the top wall of the positioning member 160.

[0113] In other embodiments, the positioning element 160 may also be designed with other structures to achieve the above-described functions. Please refer to [link / reference]. Figure 13 , Figure 13 This is a partial cross-sectional structural diagram of a beauty pen provided in other embodiments of this application.

[0114] In some embodiments, the beauty pen 10 may include a reset member 162. The reset member 162 provides an elastic reset force and may be, but is not limited to, a spring. One end of the positioning member 160 abuts against the walls of the first positioning groove 107 and the second positioning groove 108, and the other end of the positioning member 160 abuts against the reset member 162. The reset member 162 enables the elastic extension and retraction of the positioning member 160.

[0115] One end of the reset member 162 can be inserted into the positioning member 160 from the end of the positioning member 160 away from the bottom shell 140, and abuts against the positioning member 160 along the axial direction of the beauty pen 10, providing the positioning member 160 with an elastic reset force against the bottom shell 140. The other end of the reset member 162 abuts against other components, such as the mounting base 120. In other embodiments, the reset member 162 may also abut against the surface of the positioning member 160, without having to be inserted into the positioning groove.

[0116] Optionally, the reset member 162 is disposed in the assembly groove 109, and is positioned between the bottom wall of the assembly groove 109 and the positioning member 160. Both ends of the reset member 162 abut against the bottom wall of the assembly groove 109 and the positioning member 160, respectively. During the process of the beauty pen 10 switching from the first state to the second state, the positioning member 160 is compressed by the bottom shell 140 and retracts into the assembly groove 109. When the beauty pen 10 switches to the first or second state, the positioning member 160 rebounds into the corresponding positioning groove under the action of the reset member 162, forming a limiting engagement with the corresponding positioning groove.

[0117] Similarly, when the positioning member 160 springs back into the first positioning groove 107 or the second positioning groove 108, the positioning member 160 can collide with the corresponding groove wall under the action of the reset member 162, thereby making a sound. This sound can serve as a prompt sound to remind the user that the bottom shell 140 has been rotated into place.

[0118] In other embodiments, the positioning element 160 may also be designed with other structures, for example, the positioning element 160 may be a ball bearing disposed in the assembly groove 109.

[0119] Please refer to the above text. Figure 14 , Figure 14 This is an exploded structural diagram of a beauty pen provided in some other embodiments of this application.

[0120] The beauty pen 10 may include a pressing member 100, a first elastic member 110, a mounting base 120, and a bottom shell 140. The mounting base 120 has a first region and a second region. The first elastic member 110 is disposed in the first region. The bottom shell 140 is rotatably connected to the mounting base 120 and is used to rotate relative to the mounting base 120 in a preset direction X. The pressing member 100 passes through the bottom shell 140 and is fixed relative to the bottom shell 140 in the preset direction X. The bottom shell 140 is used to rotate relative to the mounting base 120 to push the pressing member 100 to move relative to the mounting base 120 to the first region or the second region. When the pressing member 100 is in the first region, the pressing member 100 abuts against the first elastic member 110, and is used to achieve elastic extension and contraction relative to the mounting base 120 under the action of the first elastic member 110.

[0121] The area where the pressing member 100 is located differs depending on the state of the beauty pen 10. Understandably, when the pressing member 100 is in the first area, the beauty pen 10 is in the first state. In some embodiments, when the pressing member 100 is in the second area, the beauty pen 10 may be in the second state, in which case the second area is provided with the second elastic member 130.

[0122] In other embodiments, when the pressing member 100 is in the second region, the beauty pen 10 can be in a third state, at which time the second region is provided with a support portion 121. The beauty pen 10 can, as described above, include multiple elastic members for allowing the pressing member 100 to elastically extend and retract, or it can be as follows... Figure 14 As shown, only one such elastic element, namely the first elastic element 110, is included. The following description uses the example of the beauty pen 10 including only one elastic element. It should be noted that the description of the beauty pen 10 above also applies to this embodiment without conflict, and similarly, the description of the beauty pen 10 in this embodiment also applies to the above embodiment without conflict.

[0123] The mounting base 120 may include a support portion 121, which is located in the second region and forms part of the bottom wall of the mounting base 120. When the pressing member 100 is in the second region, the pressing member 100 abuts against the support portion 121. Thus, the beauty pen 10 can switch between a first state and a third state. The user can rotate the bottom shell 140 as needed to switch the beauty pen 10 to a state where the pressing member 100 is elastically extendable or non-elastically extendable.

[0124] The first region and the second region can be two regions of the bottom wall of the mounting base 120. Optionally, the bottom wall of the mounting base 120 can be provided with a first telescopic groove 101 in the first region, a first elastic member 110 is disposed in the first telescopic groove 101, and a pressing member 100 is columnar, with the axial direction of the pressing member 100 parallel to the depth direction of the first telescopic groove 101.

[0125] Optionally, the pressing member 100 is used to move clockwise X1 from the first region to the second region, or counterclockwise X2 from the second region to the first region, under the push of the base shell 140. The base shell 140 may be provided with a first limiting part 141, and the mounting base 120 may be provided with a second limiting part 122. When the pressing member 100 is in the first region or the second region, the first limiting part 141 and the second limiting part 122 contact and limit it.

[0126] In this design, one of the first limiting part 141 and the second limiting part 122 can be a protrusion, and the other can be a track. The track extends along a preset direction X, and the protrusion is located within the track. When the pressing member 100 is in the first region, one end of the track abuts against the protrusion to prevent the bottom shell 140 from moving further relative to the mounting base 120 in the counterclockwise direction X2. When the pressing member 100 is in the second region, the other end of the track abuts against the protrusion to prevent the bottom shell 140 from moving further relative to the mounting base 120 in the clockwise direction X1.

[0127] Optionally, the beauty pen 10 includes a positioning member 160, which is disposed on one of the bottom shell 140 and the mounting base 120. The other of the bottom shell 140 and the mounting base 120 is provided with a first positioning groove 107 and a second positioning groove 108 spaced apart. When the pressing member 100 is in the first region, the positioning member 160 is in the first positioning groove 107. When the pressing member 100 is in the second region, the positioning member 160 is in the second positioning groove 108.

[0128] Optionally, one of the base shell 140 and the mounting base 120 is provided with an assembly groove 109, and the positioning member 160 is disposed in the assembly groove 109. When the pressing member 100 is in the first region, the first positioning groove 107 is disposed opposite to the assembly groove 109, and the end of the positioning member 160 away from the bottom wall of the assembly groove 109 is located in the first positioning groove 107. When the pressing member 100 is in the second region, the second positioning groove 108 is disposed opposite to the assembly groove 109, and the end of the positioning member 160 away from the bottom wall of the assembly groove 109 is located in the second positioning groove 108.

[0129] The above are merely some exemplary contents provided in the embodiments of this application. Any details not covered herein will not be repeated here.

[0130] In some embodiments, the beauty pen 10 also includes other components for providing additional functions in conjunction with the press component 11. Please refer to the above text. Figure 15 , Figure 15 This is an exploded structural diagram of a beauty pen provided in some embodiments of this application.

[0131] The beauty pen 10 may include a pressing component 11 and a power supply component 12. The pressing component 11 is used to press against human skin, and the power supply component 12 is electrically connected to the pressing component 11 and is used to output a microcurrent through the pressing component 11. The power supply component 12 may be electrically connected to a pressing element 100, so that when the pressing element 100 presses against the skin, the power supply component 12 can deliver a microcurrent to the human skin through the pressing element 100. The microcurrent helps to lift and tighten the skin, promote collagen production, and combat muscle relaxation. Optionally, the voltage of the power supply component 12 is 0.3-10V, such as 0.5V, 1.3V, 3.5V, etc. The current of the power supply component 12 is 50-1000μA, such as 178μA, 335μA, 500μA, 765μA, etc.

[0132] The power supply component 12 includes a power supply element 200, which provides a microcurrent. In some embodiments, the power supply element 200 is a photoelectric plate. In other embodiments, the power supply element 200 is a battery. The following description primarily uses a photoelectric plate as an example to illustrate the power supply element 200.

[0133] A photovoltaic (PV) panel, also known as a light energy panel or solar panel, is a device that converts light energy into electrical energy. Its working principle primarily relies on the photoelectric effect of semiconductors. In this embodiment, the power supply component 200 is connected to an external optical path to receive external light energy and convert it into a microcurrent. In this document, "optical path connected" means that light can be transmitted from one to the other. In other words, the connection between the power supply component 200 and the external optical path indicates that external light can be transmitted to the PV panel, but does not imply any limitation on the location of the PV panel or its relationship with other components. External light includes, but is not limited to, sunlight.

[0134] In this embodiment, a photoelectric plate is used as the power supply component 200 for the beauty pen 10, and the power supply component 200 is electrically connected to the pressing component 11. This allows the power supply component 200 to receive external light energy and convert it into microcurrent, which is then output through the pressing component 11. Thus, the beauty pen 10 can massage the skin using the pressing component 11 and improve the beauty effect by outputting microcurrent through the pressing component 11. Furthermore, no built-in power supply is required, which helps to reduce the size of the beauty pen 10 and improve its portability. Moreover, the beauty pen 10 can automatically collect light energy, so there is no need for the user to charge it.

[0135] In some embodiments, the beauty pen 10 may include a current switch for controlling the power supply component 200. The current switch may include a control mechanism electrically connected to the power supply component 200 and a trigger mechanism partially exposed on the outer surface of the beauty pen 10. The trigger mechanism may be, for example, but not limited to, a button, a push button, a turn button, etc., so that the user can control the power supply component 200 by manipulating the trigger mechanism.

[0136] In other embodiments, the beauty pen 10 may have a specific part, and the power supply component 200 may output a microcurrent by contacting this specific part with an external conductor, such as the human body. This will be used as an example in the following description. In other words, the beauty pen 10 may be configured such that when the specific part of the beauty pen 10 contacts the human body, the power supply component 12 outputs a microcurrent; and when the specific part of the beauty pen 10 separates from the human body, the power supply component 12 stops outputting the microcurrent. This will be the primary example in the following description.

[0137] The beauty pen 10 has two specific parts, one of which is a pressing component 11. The beauty pen 10 may also include a conductive component 13, which forms part of the outer surface of the beauty pen 10. The conductive component 13 can also serve as the other specific part of the beauty pen 10. The power supply component 12 is configured to output a microcurrent when both the conductive component 13 and the pressing component 11 are in contact with the human body. When at least one of the conductive component 13 and the pressing component 11 is separated from the human body, the power supply component 12 stops outputting the microcurrent.

[0138] The power supply component 12 includes a first electrode 210 and a second electrode 220, both of which are electrically connected to the power supply element 200. The first electrode 210 is electrically connected to the pressing component 11, and the second electrode 220 is electrically connected to the conductive component 13. The first electrode 210 and the second electrode 220 serve as the two poles of the power supply component 12, and are respectively electrically connected to the two poles of the power supply element 200. In some application scenarios, the user holds the part of the beauty pen 10 equipped with the conductive component 13 and uses the pressing component 11 to contact the skin. At this time, the two poles of the power supply element 200 are connected to the pressing component 11 and the conductive component 13, respectively, allowing the microcurrent output by the power supply element 200 to form a pathway through the human body. The beauty pen 10 can then use the microcurrent to stimulate the skin, achieving a microcurrent beauty effect.

[0139] The pressing component 11 can form the bottom end of the beauty pen 10. Optionally, the pressing component 11 and the conductive component 13 can form the two ends of the beauty pen 10, respectively. In other words, the conductive component 13 can form the top end of the beauty pen 10, allowing the user to hold the top end of the beauty pen 10 and massage the skin using the bottom end to achieve microcurrent beauty treatment. This design facilitates the user in applying pressure when massaging the skin using the pressing component 100. This will be used as an example in the following description. In other embodiments, the conductive component 13 can also be disposed in other locations and form other parts of the outer surface of the beauty pen 10, such as the middle outer surface of the beauty pen 10.

[0140] In this embodiment, by electrically connecting the pressing component 11 for pressing the human body and the conductive component 13 forming part of the outer surface of the beauty pen 10 to the first electrode 210 and the second electrode 220 respectively, the beauty pen 10 can form a circuit through the human body when both the pressing component 11 and the conductive component 13 are in contact with the human body, thereby enabling the power supply component 12 to output a microcurrent. Thus, the beauty pen 10 has the function of using the pressing component 11 and the conductive component 13 as a microcurrent switch, and can output a microcurrent when both the pressing component 11 and the conductive component 13 are in contact with the human body, and cut off the microcurrent when at least one of the pressing component 11 and the conductive component 13 leaves the human body, without the need for a built-in electronic control mechanism to control the microcurrent, which is beneficial to reduce the size of the beauty pen 10 and improve its portability.

[0141] In some embodiments, the beauty pen 10 may include a pen tube 14. The pen tube 14 is a tube body for mounting the various components of the beauty pen 10. The pen tube 14 has a first end 410 and a second end 420 facing away from each other. A pressing component 11 may be disposed at the first end 410, and a conductive component 13 may be disposed at the second end 420. A power supply component 12 is at least partially disposed within the pen tube 14.

[0142] There are multiple ways to connect each component to the pen tube 14. Taking the pressing component 11 as an example, the pressing component 11 can be sleeved on the pen tube 14, inserted into the pen tube 14, or docked with the pen tube 14. An exemplary connection structure is described below.

[0143] The pen tube 14 has a first mounting port 401, a second mounting port 402, and a third mounting port 403. The first mounting port 401 is located at the first end 410, the second mounting port 402 is located at the second end 420, and the third mounting port 403 is located between the first end 410 and the second end 420. Each mounting port is connected to the inner cavity of the pen tube 14. The pressing component 11 can be inserted into the first mounting port 401, the power supply component 12 can be inserted into the second mounting port 402, and the conductive component 13 can be inserted into the third mounting port 403. The pressing component 11 can make contact with the first electrode 210 inside the pen tube 14, and the conductive component 13 can make contact with the second electrode 220 inside the pen tube 14.

[0144] Understandably, both the pressing component 11 and the conductive component 13 are partially inserted into the pen tube 14, with another portion of each located outside the pen tube 14 and forming part of the outer surface of the beauty pen 10. Optionally, the outer surfaces of the pressing component 11, the pen tube 14, and the conductive component 13 are smoothly transitioned.

[0145] Optionally, the pressing assembly 11 includes a mounting base 120, a pressing member 100, and a first elastic member 110. Along the axial direction of the beauty pen 10, both ends of the first elastic member 110 abut against the mounting base 120 and the pressing member 100, respectively, so that the pressing member 100 can be elastically and telescopically disposed on the mounting base 120. The pressing member 100 is electrically connected to the power supply component 200 through the mounting base 120. The pressing member 100 can serve as a component of the pressing assembly 11 that connects to the human body. When the pressing member 100 presses against the skin and the conductive component 13 is in contact with the human body, the power supply component 12 can output a microcurrent through the pressing member 100.

[0146] The mounting base 120 can be inserted into the first mounting port 401 and is in contact with the first electrode 210 for electrical communication. The pressing assembly 11 may also include a bottom shell 140, which is fitted over the portion of the mounting base 120 located outside the pen tube 14. The pressing member 100 passes through the bottom shell 140. The bottom shell 140 can be electrically connected to the power supply member 200 through the mounting base 120. The bottom shell 140 may form part of the outer surface of the beauty pen 10. In other embodiments, the pressing assembly 11 may also be designed as other structures capable of massaging human skin, and is not limited to the structures described above.

[0147] The components of the pressing assembly 11 can be installed in front of the pen tube 14 to form a module, so that the pressing assembly 11 can be installed as a whole on the pen tube 14 or detached as a whole from the pen tube 14, which helps to improve the assembly efficiency of the beauty pen 10. Please refer to the above for the specific structure of the pressing assembly 11. The specific structures of the power supply assembly 12 and the conductive assembly 13 will be described below.

[0148] Please see Figures 15 to 17 , Figure 16 This is a three-dimensional structural schematic diagram of the power supply component provided in some embodiments of this application. Figure 17 yes Figure 16 The diagram shows the exploded structure of the power supply component.

[0149] In some embodiments, the power supply assembly 12 may include a power supply element 200 and a light-transmitting element 230. The power supply element 200 is a photoelectric plate. The light-transmitting element 230 may be stacked with the power supply element 200 and covers the power supply element 200 in a direction perpendicular to the axis of the beauty pen 10, so that external light can be transmitted to the power supply element 200 through the light-transmitting element 230.

[0150] The power supply component 200 can be housed within the pen tube 14. The light-transmitting component 230 can cover the second mounting port 402 and also cover the power supply component 200. The light-transmitting component 230 protects the power supply component 200 from external impurities that could cause it to malfunction. Optionally, the light-transmitting component 230 forms part of the outer surface of the beauty pen 10. The outer surface of the light-transmitting component 230 can smoothly transition with the outer surface of the pen tube 14. The light-transmitting component 230 is made of a light-transmitting material, such as, but not limited to, transparent plastic. The light-transmitting component 230 can be connected to the pen tube 14; for example, at least one end of the light-transmitting component 230 along the axial direction of the beauty pen 10 can be snapped onto the pen tube 14.

[0151] In other embodiments, the photoelectric plate may also form part of the outer surface of the beauty pen 10, thus eliminating the need for the light-transmitting element 230 in the beauty pen 10. The following description mainly uses the power supply assembly 12, which includes the light-transmitting element 230, as an example.

[0152] In some embodiments, the power supply assembly 12 may include a bracket 240, on which the power supply component 200, the light-transmitting component 230, the first electrode 210, and the second electrode 220 are all mounted. Optionally, the various components of the power supply assembly 12 may be installed in front of the pen tube 14 to form a module, so that the power supply assembly 12 can be installed entirely on the pen tube 14 or detached entirely from the pen tube 14, which is beneficial to improving the assembly efficiency of the beauty pen 10.

[0153] The power supply component 200 and the light-transmitting component 230 can be stacked on one side of the bracket 240, i.e., the side of the bracket 240 facing outwards. The first electrode 210 and the second electrode 220 can be disposed on the other side of the bracket 240 to facilitate electrical connection with the pressing component 11 and the conductive component 13. Both the first electrode 210 and the second electrode 220 can be electrically connected to the power supply component 200 via wires. The power supply component 12 is used to be inserted into the pen tube 14 through the second mounting port 402 after assembly. In other embodiments, the power supply component 200 and the light-transmitting component 230 can also be directly fixed to the pen tube 14 without being disposed on the bracket 240.

[0154] Optionally, the components of the pressing assembly 11 and the power supply assembly 12 can be assembled into modular pressing assemblies 11 and 12 before being installed on the pen tube 14, and then installed on the pen tube 14 respectively, to improve the assembly efficiency of the beauty pen 10. The pressing assembly 11 and the power supply assembly 12 can be connected within the pen tube 14 to form a limiting fit, thereby reducing the installation structure required on the pen tube 14 for fixing the pressing assembly 11 and the power supply assembly 12.

[0155] Please refer to the following: Figures 15 to 18 , Figure 18 This is a three-dimensional structural diagram of some of the beauty pens provided in some embodiments of this application. Figure 18 The diagram shows the structure of the beauty pen 10 without the pen tube 14.

[0156] The portion of the pressing component 11 located inside the pen tube 14 may be provided with a first snap-fit ​​portion 170, and the portion of the power supply component 12 located inside the pen tube 14 may be provided with a second snap-fit ​​portion 250. The pressing component 11 and the power supply component 12 can be snapped and fixed inside the pen tube 14 through the first snap-fit ​​portion 170 and the second snap-fit ​​portion 250.

[0157] The pressing component 11 is inserted into the pen tube 14 through a first mounting port 401, which is located on the end face of the pen tube 14. The power supply component 12 is inserted into the pen tube 14 through a second mounting port 402, which is located on the side wall of the pen tube 14. By engaging with the pressing component 11 and the power supply component 12, which are inserted into the pen tube 14 from different directions, one of the pressing component 11 and the power supply component 12 can be limited in its insertion direction, while the other can be fixedly connected to the pen tube 14, thus achieving a fixed connection between the pressing component 11, the power supply component 12, and the pen tube 14.

[0158] Optionally, the first snap-fit ​​portion 170 is disposed on the mounting base 120, the second snap-fit ​​portion 250 is disposed on the bracket 240, and the bracket 240 is further provided with a third snap-fit ​​portion 241, through which the bracket 240 is snapped onto the pen tube 14. To improve photoelectric conversion efficiency, the power supply component 200 can be elongated, and its length direction is approximately parallel to the axis of the beauty pen 10; correspondingly, the light-transmitting component 230 and the bracket 240 can also be elongated, and their length directions are approximately parallel to the length direction of the power supply component 200. The third snap-fit ​​portion 241 can be disposed at at least one end of the bracket 240 along the axis of the beauty pen 10 to facilitate the installation of the power supply component 12 on the pen tube 14.

[0159] In this design, one of the first latching portion 170 and the second latching portion 250 can be a groove, and the other can be a protrusion adapted to the groove, so that the first latching portion 170 and the second latching portion 250 can be latched together. During assembly, the pressing component 11 can be inserted into the pen tube 14 through the first mounting port 401, and then the power supply component 12 can be inserted into the pen tube 14 through the second mounting port 402, and latched onto the second latching portion 250 of the pressing component 11 through the first latching portion 170, and latched onto the pen tube 14 through the third latching portion 241. The second latching portion 250 can be provided on the side of the bracket 240 opposite to the power supply component 200, and the side of the bracket 240 opposite to the power supply component 200 can be abutted against the side of the mounting base 120 where the first latching portion 170 is provided.

[0160] The specific shapes of the first latching portion 170 and the second latching portion 250 can be designed as needed, for example... Figure 15and Figure 16 As shown, both the first latching portion 170 and the second latching portion 250 can be T-shaped. In other embodiments, the pressing component 11 and the power supply component 12 can also be connected within the pen tube 14 by other means, such as magnetic adsorption.

[0161] When the pressing component 11 and the power supply component 12 are assembled, the pressing component 11 makes contact with the first electrode 210 of the power supply component 12 through the mounting base 120, so that the power supply component 12 can output a microcurrent through the pressing component 11. Optionally, the first electrode 210 is a metal spring.

[0162] Please see Figures 16 to 19 , Figure 19 This is a partial cross-sectional structural diagram of the beauty pen provided in some embodiments of this application.

[0163] When the pressing component 11 and the power supply component 12 are assembled, the first electrode 210 can abut against the mounting base 120 to achieve contact and conduction with the mounting base 120. Since the metal spring has a certain elastic deformation, the first electrode 210 and the mounting base 120 can be designed with a certain pre-compression amount to prevent the pressing component 11 and the power supply component 12 from failing to conduct when assembled due to assembly errors.

[0164] The shape of the first electrode 210 can be designed as needed. Optionally, the first electrode 210 includes a first conductive portion 211 and a second conductive portion 212. The first conductive portion 211 is connected to the bracket 240, and the connection method is, for example, but not limited to, snap-fit ​​or welding. The second conductive portion 212 is bent and connected to the first conductive portion 211 to abut against the mounting base 120. The power supply unit 200 can be electrically connected to the first conductive portion 211 or the second conductive portion 212 via a wire.

[0165] In some embodiments, a mounting portion 242 may protrude from the side of the bracket 240 opposite to the power supply component 200 for mounting the first electrode 210. A first conductive portion 211 may be inserted into the mounting portion 242. Optionally, the bracket 240 may have at least one reinforcing portion 243, which protrudes from the mounting portion 242 on the same side of the bracket 240 and may be connected to the mounting portion 242. The reinforcing portion 243 may serve as a reinforcing rib to improve the overall strength of the bracket 240 and prevent deformation of the bracket 240 during assembly. The bracket 240 may also have other reinforcing portions 243 connected to the reinforcing portion 243 to further enhance the overall strength of the bracket 240.

[0166] The second electrode 220 can also be a metal spring, and its structure can be the same as or similar to that of the first electrode 210. The second electrode 220 can also be mounted on the bracket 240. Similarly, the bracket 240 also has another mounting portion 242 for mounting the second electrode 220. The mounting method of the second electrode 220 on the bracket 240 is roughly the same as that of the first electrode 210. The second electrode 220 can abut against the conductive component 13 during assembly to achieve an electrical connection between the power supply component 200 and the conductive component 13.

[0167] Please see Figures 19 to 23 , Figure 20 yes Figure 15 A partially exploded view of the beauty pen in the embodiment from another perspective. Figure 21 This is a three-dimensional structural schematic diagram of the conductive component provided in some embodiments of this application. Figure 22 yes Figure 21 The diagram shows an exploded view of the conductive component. Figure 23 This is a partial cross-sectional structural diagram of the beauty pen provided in some embodiments of this application.

[0168] In some embodiments, the conductive component 13 includes a conductive element 310, which forms part of the outer surface of the beauty pen 10 and is electrically connected to the power supply component 200 via a second electrode 220. Optionally, the conductive element 310 is disposed at the second end 420 of the pen tube 14. The conductive element 310 may be sleeved on the second end 420 of the pen tube 14, and a conductive portion 311 protrudes from the inner wall of the conductive element 310. The conductive portion 311 passes through the side wall of the second end 420 and contacts and conducts electricity with the second electrode 220.

[0169] The conductive part 311 can be a strip-shaped protrusion extending approximately along the axial direction of the beauty pen 10. The second end 420 of the pen tube 14 can have a mounting hole 404, which is a strip-shaped through hole extending approximately along the axial direction of the beauty pen 10. The mounting hole 404 is a through hole formed in the side wall of the second end 420, and one end of the mounting hole 404 extends to the end face of the second end 420. The conductive part 311 can be inserted into the mounting hole 404 to pass through the side wall of the second end 420.

[0170] During the assembly of the conductive component 310, the conductive component 310 can be sleeved onto the second end 420 of the pen tube 14 along the axial direction of the beauty pen 10, while the conductive part 311 can be inserted into the assembly hole 404. When the conductive component 310 is assembled, the conductive part 311 will abut against the second electrode 220 to realize the electrical connection between the conductive component 13 and the power supply component 12.

[0171] In this embodiment, the conductive part 311 and the mounting hole 404 are designed as strips, so that when the conductive component 310 is assembled into the pen tube 14, the conductive part 311 and the mounting hole 404 can serve as positioning structures to achieve accurate installation of the conductive component 310 and avoid the conductive component 310 failing to make contact with the second electrode 220 due to inaccurate installation. Optionally, the conductive part 311 has a locking part 312 at one end near the second electrode 220. The locking part 312 can be stepped. When the conductive component 310 is assembled, the locking part 312 will engage with one end wall of the mounting hole 404 to further improve the installation accuracy of the conductive component 310. In other embodiments, the conductive component 310 can also be designed in other shapes and installed into the pen tube 14 in other ways. For example, the conductive component 310 can be inserted into the pen tube 14 in a direction perpendicular to the axial direction of the beauty pen 10.

[0172] Optionally, the outer surface of the second end 420 of the pen tube 14 may be provided with an adapter groove 405, and the conductive element 310 may be disposed in the adapter groove 405 and sleeved on the second end 420 of the pen tube 14 to improve the flushness between the outer surface of the conductive element 310 and the outer surface of the pen tube 14.

[0173] The adapter groove 405, at both ends along the direction perpendicular to the axial direction of the beauty pen 10, can be arranged along the axial direction of the beauty pen 10, so that the adapter groove 405 forms a shape where one end is higher and the other lower along the axial direction of the beauty pen 10. Correspondingly, the conductive element 310, at both ends along the direction perpendicular to the axial direction of the beauty pen 10, can be arranged along the axial direction of the beauty pen 10, so that the conductive element 310 forms a shape where one end is higher and the other lower along the axial direction of the beauty pen 10. For example, but not limited to... Figure 21 As shown, the end face of the conductive member 310 is elliptical in shape and is inclined to the axial direction of the beauty pen 10. The conductive part 311 can be disposed on the inner wall of the relatively higher end of the conductive member 310 along the axial direction of the beauty pen 10, so as to increase the insertion amount of the conductive part 311 in the pen tube 14, which helps to reduce the installation difficulty of the second electrode 220.

[0174] In some embodiments, the conductive component 13 may include a latching member 320, which is fixed to the conductive component 310 and connected to the pen tube 14. The conductive component 310 can be fixed to the second end 420 of the pen tube 14 by the latching member 320. The latching member 320 can be inserted into the third mounting port 403 of the pen tube 14 and fastened to the second end 420. The conductive component 13 is inserted into the third mounting port 403 by the latching member 320.

[0175] The conductive element 310 can be disposed on the inner wall of its top end. The inner wall of the top end of the conductive element 310 can be provided with screw holes, and the fastener 320 can be fixed to the conductive element 310 by screws. In other embodiments, the fastener 320 can also be fixed to the conductive element 310 by other means, such as, but not limited to, bonding or welding.

[0176] A latching part 321 may be provided on one side of the latching member 320, and the number of latching parts 321 may be one or more. For example, there may be multiple latching parts 321, which may be arranged in a circumferential direction. When assembling the conductive component 13, the conductive member 310 may be sleeved on the second end 420 of the pen tube 14 along the axial direction of the beauty pen 10, and the conductive part 311 may be inserted into the mounting hole 404. The latching member 320 may be inserted into the third mounting port 403 through at least one latching part 321 and latched on the second end 420 of the pen tube 14. The inner wall of the second end 420 of the pen tube 14 may be provided with a latch adapted to the latching part 321.

[0177] In other embodiments, the conductive component 13 may also be fixed to the second end 420 of the pen tube 14 in other ways, such as by threading it to the second end 420 of the pen tube 14, rather than by snapping it to the pen tube 14 with the snap fastener 320.

[0178] In this embodiment, the components of the conductive assembly 13 can be assembled into modules before being assembled into the pen tube 14, and then installed together at the second end 420 of the pen tube 14 during assembly, which improves assembly efficiency. The conductive assembly 13 is similar to the cap of the beauty pen 10, and can be easily inserted into the second end 420 of the pen tube 14 to serve as a specific part of the beauty pen 10 for establishing conductivity between the human body and the power supply assembly 12. Understandably, the outer surface of the pen tube 14 is insulated.

[0179] Optionally, the pressing component 11, the power supply component 12, and the conductive component 13 all adopt a modular design. During the assembly of the beauty pen 10, the three modules—pressing component 11, power supply component 12, and conductive component 13—can be installed onto the pen tube 14 after their respective assembly is completed. No welding or bonding operations are required during the assembly process; assembly can be completed simply by utilizing the snap-fit ​​and abutment cooperation between the components. Thus, the beauty pen 10 can be assembled quickly and conveniently.
