[0001] This application relates to the field of testing instrument technology, specifically to a skin testing instrument. Background Technology

[0002] A skin analyzer is a device that analyzes a user's skin condition and is widely used in beauty, medical, and other fields. By analyzing the health of a user's skin, a skin analyzer can help users customize more suitable skincare plans to meet their skincare needs.

[0003] In related technologies, common skin analyzers use optical zoom, but this makes the structure of the detection module more complex and takes up more space, resulting in a larger size and weight of the skin analyzer, making it less convenient to use and reducing the user experience. Utility Model Content

[0004] This application provides a skin analyzer with an optimized detection module structure, thereby reducing the size of the skin analyzer and improving the user experience.

[0007] A movable bracket is movably mounted in the mounting cavity;

[0008] A detection camera is mounted on the movable bracket, and the lens of the detection camera is exposed through the detection hole; and,

[0009] A control element, movably mounted on the housing and driven connected to the movable bracket, is used to drive the movable bracket to move along the axis of the detection hole.

[0010] In some embodiments, the control element is rotatably mounted on the housing to be able to rotate about the outer periphery of the housing, and the rotation of the control element causes the movable bracket to move along the axis of the detection hole.

[0011] In some embodiments, the control element is a sleeve, which is fitted onto the housing and can rotate relative to the housing. The inner peripheral wall of the control element is provided with a spiral groove, which extends rotatably along the axis of the sleeve. The surface of the movable bracket is provided with a protrusion, which passes through the housing and is inserted into the spiral groove. The protrusion can slide along the groove wall of the spiral groove.

[0012] In some embodiments, a guide groove is provided on the surface of the housing, the guide groove extends along the axis of the detection hole, and the protrusion is also inserted into the guide groove and slides along the length direction of the guide groove.

[0013] In some embodiments, the spiral grooves are provided in two sets, and the two sets of spiral grooves are arranged opposite to each other. The movable bracket is provided with a mounting hole, the axis of the mounting hole is perpendicular to the axis of the detection hole, and the skin detector further includes a movable shaft, which is provided through the mounting hole, and the two ends of the movable shaft serve as the protrusions.

[0014] The two ends of the movable shaft are respectively inserted into two opposite spiral grooves.

[0015] In some embodiments, the housing includes an upper shell, a middle shell, and a lower shell connected sequentially along the axis of the detection hole. The detection hole passes through the end of the upper shell away from the middle shell. The control element is mounted on the middle shell, and the upper shell and the lower shell clamp the control element.

[0016] In some embodiments, the control element is a sleeve, which is sleeved on the outer shell of the middle shell. The upper and lower ends of the sleeve are provided with limiting grooves, which extend along the periphery of the sleeve. The ends of the upper shell and the lower shell are provided with limiting protrusions, which extend in an annular shape corresponding to the limiting grooves and are inserted into the limiting grooves.

[0017] In some embodiments, the inner wall of the upper shell is provided with a plug-in member, the end of the lower shell is provided with a snap-fit ​​member, and the middle shell is provided with a plug-in groove and a snap-fit ​​hole respectively. The plug-in member is used to be inserted into the plug-in groove, and the snap-fit ​​member is used to be snapped into the snap-fit ​​hole.

[0018] In some embodiments, the control element is slidably mounted on the housing to be movable along the axis of the detection hole, and the control element is fixedly connected to the movable bracket.

[0019] In some embodiments, a positioning structure is provided between the movable bracket and the housing, the positioning structure being used to restrict the rotation of the movable bracket along the circumferential direction of the detection hole.

[0020] In some embodiments, the skin detector further includes a circuit board mounted in the mounting cavity and a first comb tooth and a second comb tooth for contacting the skin.

A movable support is located within the mounting cavity, and a detection camera is mounted on the movable support. The camera lens is exposed through the detection hole. A movable control component is mounted on the housing. By moving this control component, the movable support is driven to move back and forth along the axis of the detection hole, thereby adjusting the position of the detection camera to achieve a zoomed view. Both the detection camera and the movable support move back and forth within the mounting cavity, minimizing the space occupied. Furthermore, the absence of an optical zoom lens structure further reduces the space required in the mounting cavity. This design optimizes the overall structure of the skin detector, improves space utilization, and reduces the weight and size of the skin detector. It also reduces pressure on the user's arm and wrist during use, thus improving the user experience. Attached Figure Description

The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0042] like Figures 1 to 13As shown in the figure, this application provides a skin detector. In this embodiment, the skin detector can detect areas such as skin pores and scalp hair follicles. The skin detector includes a housing 1, a detection camera 41, a movable support 2, and a control component 3. The housing 1 has a mounting cavity 121 and a detection hole 111 communicating with the mounting cavity 121. The movable support 2 is movably mounted in the mounting cavity 121. The detection camera 41 is mounted on the movable support 2, and the lens of the detection camera 41 is exposed through the detection hole 111. The control component 3 is movably mounted in the housing 1 and is driven and connected to the movable support 2 for driving the movable support 2 to move along the axis of the detection hole 111.

[0043] In related technologies, the detection module of a skin analyzer includes a camera and a lens mounted on the camera. This camera is an optical zoom type, and the internal structure of the lens is relatively large, resulting in a large overall size of the detection module. A large space is also required when adjusting the zoom of the lens, which also increases the weight and size of the skin analyzer. It is difficult for users to hold and puts a lot of strain on their wrists.

[0044] In this embodiment, the skin detector includes a housing 1, within which a mounting cavity 121 and a detection hole 111 are provided. A movable support 2 is located within the mounting cavity 121, and a detection camera 41 is mounted on the movable support 2. The lens of the detection camera 41 is exposed through the detection hole 111. A movable control component 3 is mounted on the housing 1. By moving the control component 3, the movable support 2 is driven to move back and forth along the axis of the detection hole 111, thereby adjusting the position of the detection camera 41 to achieve the purpose of zooming in and out of the field of view. Both the detection camera 41 and the movable support 2 are fixed within the mounting cavity 121, minimizing the space occupied by the cavity. Furthermore, the absence of an optical zoom lens structure further reduces the space occupied by the mounting cavity 121. This design optimizes the overall structure of the skin detector, improves space utilization, and reduces the weight and size of the skin detector. This also reduces pressure on the user's arm and wrist during use, thus improving the user experience.

[0045] In some embodiments, the control element 3 is rotatably mounted on the housing 1 so as to be able to rotate about the outer periphery of the housing 1, and the rotation of the control element 3 drives the movable bracket 2 to move along the axis of the detection hole 111.

[0046] Specifically, the user pushes the control component 3 to rotate by hand. The mounting cavity 121 also has a transmission mechanism that connects the control component 3 and the movable bracket 2 respectively, thereby driving the movable bracket 2 to move. Adjusting by rotation can make the movable bracket 2 move more accurately, thereby ensuring more precise adjustment of the camera's field of view. This setting enables the rotation of the control component 3 to drive the movable bracket 2 to move.

[0047] In another embodiment, the control element 3 is slidably mounted on the housing 1 so as to be movable along the axis of the detection hole 111, and the control element 3 is fixedly connected to the movable bracket 2.

[0048] Specifically, one end of the control component 3 is fixedly connected to the movable bracket 2. Pushing the control component 3 to slide along the axis of the detection hole 111 directly drives the movable bracket 2 to move back and forth. This setting is convenient to operate and has a low difficulty of use.

[0049] In some embodiments, the control member 3 is a sleeve, which is sleeved on the housing 1 and can rotate relative to the housing 1. The inner peripheral wall of the control member 3 is provided with a spiral groove 31, which extends rotatably along the axis of the sleeve. The surface of the movable bracket 2 is provided with a protrusion, which passes through the housing 1 and is inserted into the spiral groove 31. The protrusion can slide along the groove wall of the spiral groove 31.

[0050] Specifically, the control component 3 is a sleeve structure with a spiral groove 31 on its inner wall. The spiral groove 31 extends from bottom to top and is a groove with both ends connected. The two ends of the spiral groove 31 are respectively located at the upper and lower ends of the sleeve. A protrusion is inserted into the spiral groove 31. When the sleeve structure is rotated, the protrusion is pushed and continuously slides along the extension path of the spiral groove 31. The movement of the movable bracket 2 is controlled by moving the position of the protrusion. This configuration allows the movement of the movable bracket 2 to be driven by rotating the control component 3. In some other embodiments, a trapezoidal lead screw and a nut seat rotatably connected to the trapezoidal lead screw are provided in the mounting cavity 121. The movable bracket 2 is installed in the nut seat. The inner wall of the control component 3 is fixedly connected to the trapezoidal lead screw. By rotating the control component 3, the trapezoidal lead screw rotates, thereby realizing the movement of the nut seat in the front-back direction.

[0051] In some embodiments, a guide groove 122 is provided on the surface of the housing 1. The guide groove 122 extends along the axis of the detection hole 111, and the protrusion is also inserted into the guide groove 122 and slides along the length direction of the guide groove 122.

[0052] Specifically, the protrusion passes through the guide groove 122 and is inserted into the spiral groove 31. The guide groove 122 has sidewalls at both ends, which limit the protrusion. When the control member 3 rotates to a certain extent, the protrusion will abut against either end of the guide groove 122. At this point, the control member 3 can no longer rotate in this direction. The detection camera 41 may be at its maximum or minimum field of view at this time. This design can prevent the control member 3 from rotating excessively and also prevent the protrusion from disengaging from the spiral groove 31. In some other embodiments, abutment portions are provided at both ends of the spiral groove 31. When the protrusion slides to this position, it will abut against the abutment portions.

[0053] In some embodiments, the spiral groove 31 is provided in two sets, and the two sets of spiral grooves 31 are arranged opposite to each other. The movable bracket 2 is provided with a mounting hole 22, the axis of the mounting hole 22 is perpendicular to the axis of the detection hole 111. The skin detector also includes a movable shaft 21, which is inserted through the mounting hole 22, and the two ends of the movable shaft 21 are protrusions. The two ends of the movable shaft 21 are respectively inserted into the two opposite spiral grooves 31.

[0054] Specifically, two sets of co-rotating spiral grooves 31 are provided on the inner wall of the sleeve. The two spiral grooves 31 are arranged opposite each other and rotate clockwise from top to bottom along the inner wall of the sleeve. The path lengths of the two spiral grooves 31 are the same. The two ends of the movable shaft 21 are respectively inserted into the two spiral grooves 31, which can limit the rotation of the movable shaft 21. The two ends of the movable shaft 21 are blocked by the bottom wall of the spiral grooves 31, which limits the axial movement of the movable shaft 21. Under the combined restriction, the movable shaft 21 can only slide along the inner wall of the spiral grooves 31, and the movable shaft 21 itself cannot rotate. During assembly, the movable bracket 2 needs to be assembled on the shell. Since assembly from the outside in is not possible inside the body 1, a mounting hole 22 is provided on the movable bracket 2. The axis of the mounting hole 22 is perpendicular to the axis of the detection hole 111. A movable shaft 21 is inserted into the mounting hole 22, with its two ends serving as two protrusions. The housing 1 is then wrapped around the movable bracket 2 for assembly. The movable shaft 21 is long enough to pass through the spiral groove 31 in the control component 3. The movable shaft 21 can move within the mounting hole 22 and is not completely abutted against the bottom wall of the spiral groove 31. This design prevents the movable shaft 21 from getting stuck in the spiral groove 31 when the control component 3 is rotated, ensuring rotational stability. This design simplifies the drive structure, improves space utilization, ensures stable movement of the movable bracket 2, and allows for fine-tuning of the movement distance of the control component 3.

[0055] Furthermore, two opposing support members 23 are provided on the movable bracket 2. The support member 23 is a support column structure. The mounting hole 22 is formed from the end of the support column at one end to the end of the support column at the other end. The mounting hole 22 is a through hole. The movable shaft 21 passes through the two support columns. The support columns protrude from the outer peripheral surface of the movable bracket 2 and cover most of the area of ​​the movable shaft 21. The degree of freedom of the movable shaft 21 in the radial direction is restricted by the mounting columns. This can increase the installation stability of the movable shaft 21. Therefore, only part of the movable shaft 21 is exposed outside the support columns.

[0056] This embodiment can also be combined with the above-mentioned embodiment with guide groove 122, where the exposed part of the movable shaft 21 passes through guide groove 122 and is inserted into spiral groove 31, which facilitates the assembly of the overall structure.

[0057] In some embodiments, the housing 1 includes an upper housing 11, a middle housing 12, and a lower housing 13 connected sequentially from top to bottom along the axis of the detection hole 111. The detection hole 111 passes through the end of the upper housing 11 away from the middle housing 12. The control member 3 is installed on the middle housing 12, and the upper housing 11 and the lower housing 13 clamp the control member 3.

[0058] Specifically, the housing 1 has a columnar structure and is divided into three parts. A detection hole 111 is located at the top of the upper housing 11. The upper housing 11, middle housing 12, and lower housing 13 together form a mounting cavity 121. The upper housing 11 and middle housing 12 are connected together by bolts, while the middle housing 12 and lower housing 13 are detachably connected. Parts of the upper housing 11 and lower housing 13 protrude radially from the middle housing 12, thus forming a mounting space between the lower end of the upper housing 11 and the upper end of the lower housing 13. The control component 3 is located within this mounting space and is clamped by the upper housing 11 and lower housing 13. This arrangement ensures a tight installation and limits the movement of the control component 3, preventing it from easily detaching from the middle housing 12. In other embodiments, the middle housing 12 has an operating hole, and the control component 3 is installed inside the middle housing 12, with a portion of the control component 3 exposed through the operating hole.

[0059] In some embodiments, the control member 3 is a sleeve, which is sleeved on the middle shell 12. The upper and lower ends of the sleeve are recessed with limiting grooves 32, which extend along the periphery of the sleeve. The ends of the upper shell 11 and the lower shell 13 are both provided with limiting protrusions 132, which extend in an annular shape corresponding to the limiting grooves 32, and are inserted into the limiting grooves 32.

[0060] Specifically, in this embodiment, the control component 3 is a sleeve fitted onto the middle shell 12. The upper and lower ends of the sleeve are respectively limited by the upper shell 11 and the lower shell 13. Both the upper and lower ends of the control component 3 are provided with a ring of limiting grooves 32. The lower end of the upper shell 11 and the upper end of the lower shell 13 are each provided with a ring of limiting protrusions 132. The limiting protrusions 132 are inserted into the limiting grooves 32 to limit the control component 3. The edges of the limiting protrusions 132 are arc-shaped, and the bottom of the limiting grooves 32 is also arc-shaped. This arrangement restricts the movement of the control component 3 along its axis. Simultaneously, when the control component 3 rotates, the friction between the upper shell 11, the lower shell 13, and the control component 3 is reduced, making the rotation smoother. In other embodiments, the limiting protrusions 132 are located at the upper and lower ends of the control component 3, and the limiting grooves 32 are located at the lower end of the upper shell 11 and the upper end of the lower shell 13.

[0061] In some embodiments, the inner wall of the upper shell 11 is provided with a connector 114, the end of the lower shell 13 is provided with a fastener 131, and the middle shell 12 is provided with a connector groove 124 and a fastening hole 125. The connector 114 is used to insert into the connector groove 124, and the fastener 131 is used to snap into the fastening hole 125.

[0062] Specifically, the upper shell 11 is fitted over the middle shell 12. The inner wall of the upper shell 11 is provided with a connector 114, which is a convex strip structure. The outer peripheral wall of the middle shell 12 is provided with a connector groove 124 for the connector 114 to be inserted into. The upper shell 11 and the middle shell 12 are also connected by bolts. The bolts pass through the top end of the upper shell 11 and are screwed to the upper end of the middle shell 12. When the upper shell 11 is connected to the middle shell 12, the connector 114 is inserted into the connector groove 124. This prevents the upper shell 11 from being positioned relative to the middle shell. The upper shell 11, middle shell 12, and lower shell 13 are connected by a snap-fit ​​hole 125 near the lower edge of the middle shell 12, and a protruding snap-fit ​​member 131 is provided on the upper edge of the lower shell 13. The snap-fit ​​member 131 is used to snap into the snap-fit ​​hole 125 to connect the lower shell 13 and the middle shell 12. This arrangement ensures a stable connection between the upper shell 11, middle shell 12, and lower shell 13, and facilitates assembly. The insertion groove 124 also has a guiding function, which can prevent mistaken connection during assembly. In some other embodiments, the upper shell 11 and the middle shell 12 are also connected by a snap-fit ​​structure, which makes the assembly more efficient and the disassembly and assembly more convenient.

[0063] In some embodiments, a positioning structure is provided between the movable bracket 2 and the housing 1, the positioning structure being used to restrict the rotation of the movable bracket 2 along the circumferential direction of the detection hole 111.

[0064] Specifically, the positioning structure includes a positioning groove 24 on the movable support 2 and a positioning protrusion 123 on the middle shell 12. The positioning protrusion 123 is inserted into the positioning groove 24 to restrict the rotation of the movable support 2. Furthermore, when the movable support 2 moves in the vertical direction, it will not disengage from the positioning protrusion 123 or rotate, further improving the stability of the movable support 2's movement. In other embodiments, the positioning groove 24 is located on the inner peripheral wall of the middle shell 12, and the positioning protrusion 123 is located on the surface of the movable support 2.

[0065] In some embodiments, the skin detector further includes a supplementary light 42, which is installed in the housing 1 and close to the detection camera 41. The orientation of the supplementary light 42 is the same as that of the detection camera 41. The detection hole 111 is provided with a light-transmitting cover, and the light-transmitting cover is sealed on the detection hole 111.

[0066] Specifically, a light-transmitting seat 112 is provided at the upper end of the housing 1. The light-transmitting seat 112 is bolted to the housing 1. The light-transmitting seat 112 is made of transparent material. The detection hole 111 passes through the light-transmitting seat 112 and the housing 1 and communicates with the mounting cavity 121. The detection camera 41 can be seen through the detection hole 111. A light-transmitting cover is provided on the detection hole 111. The light-transmitting cover is a sealed waterproof cover made of a high-transmittance material, which can prevent water and impurities from entering the mounting cavity 121. When the user needs to zoom in or out, he can control the detection camera 41 to move closer. Alternatively, the detection camera 41 can be positioned away from the detection hole 111, and will not extend beyond it. A supplementary light 42 is provided around the detection hole 111, configured as a ring-shaped light plate. The supplementary light 42 is located inside the upper shell 11, which has multiple light-transmitting holes corresponding to the LEDs on the light plate. The light emitted by the supplementary light 42 can pass through the light-transmitting base 112. With this configuration, when the skin detector is used to detect the skin, the supplementary light 42 is turned on, and the condition of the hair follicles can be clearly seen through the detection camera 41 even in low-light conditions.

[0067] Furthermore, when the skin analyzer is not in use, a cover 113 can be snapped onto the light-transmitting base 112 to prevent the user end of the skin analyzer from being exposed.

[0068] In some embodiments, the skin detector further includes a circuit board 53 mounted in the mounting cavity 121 and a first comb tooth 51 and a second comb tooth 52 for contacting the skin. The first comb tooth 51, the second comb tooth 52 and the detection hole 111 are disposed on the same surface. The first comb tooth 51 and the second comb tooth 52 are both conductive and electrically connected to the circuit board 53. The first comb tooth 51 is either the positive or negative electrode, and the second comb tooth 52 is the other. After the first comb tooth 51 and the second comb tooth 52 contact the skin, they form a current loop. The circuit board 53 provides current for stimulating the skin.

[0069] Specifically, both sets of comb teeth are made of metal, which is conductive. A battery, circuit board 53, and switch button 54 are installed inside the housing 1. A charging port 55 is located at the bottom of the lower housing 13. The charging port 55 is used to connect a data cable to charge the battery, and the battery is used to power the circuit board 53. The detection camera 41, the two sets of comb teeth, the switch button 54, and the fill light 42 are all electrically connected to the circuit board 53. The switch button 54 controls the switching on and off of the detection camera 41 and the fill light 42. The first comb tooth 51 and the second comb tooth 52 are respectively a positive electrode and a negative electrode. When the two are in contact with the scalp at the same time, they can form a microcurrent circuit. The control switch can also control the circuit board 53 to output a microcurrent for microcurrent treatment of the scalp. The two sets of comb teeth can better comb the hair and prevent the detection camera 41 from being blocked when detecting hair follicles.

[0070] The skin detector provided in the embodiments of this application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
