Description

Technical Field

[0001] This utility model relates to the field of electropolarized light skin detectors, and in particular to a polarized light skin detector. Background Technology

[0002] With the continuous development of beauty and skin health testing technologies, an increasing number of intelligent testing devices are being introduced into the fields of skin care and medical aesthetics. Among them, polarized light skin analyzers, as devices capable of visually analyzing skin conditions, have been widely used to assess multi-dimensional skin parameters such as moisture, pores, pigmentation, oil, and texture due to their non-invasive testing method and high image clarity. These devices acquire images using a polarized light source and a camera, and by combining image processing and data analysis technologies, they can achieve accurate diagnosis of skin health conditions.

[0003] In existing technologies, polarized light skin analyzers typically use a fixed structure or a simple angle-adjustable structure to support the main body of the instrument, and the detection process often relies on manual adjustment of the instrument's height and angle to adapt to the facial features of different users. These devices mainly use a fixed bracket to position the detection component at a certain angle, and then use traditional methods to acquire images of the user's face. In order to achieve detailed imaging of different facial areas, existing devices are usually equipped with height-adjustable lens components or simple adjustment mechanisms to improve the stability and clarity of the images.

[0004] However, due to the limited design of the height adjustment structure in the existing technology, it is often impossible to meet the user's flexible adjustment needs for the angle and height of the detection instrument in different usage scenarios. The adjustment process is cumbersome and lacks precision, which in turn affects the stability of the detection position and the imaging effect. Therefore, a polarized light skin detector is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a polarized light skin detector, which aims to improve the problem that the existing technology cannot meet the user's need for flexible adjustment of the angle and height of the detector in different usage scenarios.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a polarized light skin detector, comprising an instrument body, a display screen on one side of the instrument body, a detection mechanism on the rear side of the inner wall of the instrument body, a breathing light on the upper surface of the instrument body near the opening, a rotatable chin pad on the lower side of the bottom of the inner wall of the instrument body near the opening, a base directly below the instrument body, and an adjustment component installed on the lower surface of the instrument body;

[0007] The adjustment assembly includes a connecting block, a rotating plate, a slider, and a bidirectional lead screw. The upper surface of the connecting block is fixedly connected to the front side of the lower surface of the instrument body. One side of the outer wall of the rotating plate is rotatably connected to the outer wall of the connecting block. One side of the slider is rotatably connected to one side of the outer wall of the rotating plate. The outer wall of the bidirectional lead screw is threadedly connected to the inside of the slider. One end of the bidirectional lead screw is rotatably connected to the inner wall of the base, and the other end of the bidirectional lead screw is rotatably connected to the inside of the base. A hinge block is fixedly connected to the rear side of the lower surface of the instrument body. A bracket is rotatably connected to the outer wall of the hinge block, and one side of the outer wall of the bracket is fixedly connected to one side of the outer wall of the base.

[0008] Furthermore, a sleeve is fixedly connected to the top of the inner wall of the instrument body, a slide rod is slidably connected inside the sleeve, and a forehead support is fixedly connected to the lower end of the slide rod.

[0009] Furthermore, a fixing box is fixedly connected to one side of the outer wall of the sleeve, and a T-shaped rod is slidably connected inside the fixing box.

[0010] Furthermore, a buckle plate is rotatably connected to the outer wall of the T-shaped rod, and a locking block is fixedly connected to one end of the T-shaped rod.

[0011] Furthermore, a spring is fitted on the outer wall of the T-shaped rod, with one end of the spring abutting against one side of the inner wall of the fixing box and the other end of the spring abutting against one side of the outer wall of the locking block.

[0012] Furthermore, a limiting block is fixedly connected to the upper end of the slide rod, and the outer wall of the limiting block is slidably connected to the inner wall of the sleeve.

[0013] Furthermore, one side of the outer wall of the card block is provided through the side wall of the sleeve, and the outer wall of the card block is slidably connected to a hole opened inside the slide rod.

[0014] Furthermore, one side of the outer wall of the buckle plate abuts against one side of the outer wall of the fixing box, and one end of the bidirectional lead screw is fixedly connected to a knob.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, by rotating the knob, the bidirectional lead screw drives the rotating plate on the outside of the slider to rotate. The rotation of the rotating plate facilitates the connection block to push the hinge block on one side of the lower surface of the instrument body to rotate inside the bracket. The rotation of the hinge block inside the bracket facilitates the adjustment of the height according to different usage angles, thereby improving the practicality of the instrument.

[0017] 2. In this utility model, by moving the buckle plate, the buckle plate causes the T-shaped rod to slide inside the fixed box. Then, the T-shaped rod pulls the buckle plate away from the sliding rod. By pulling the forehead support and then releasing the buckle plate, the reaction force of the spring is used to fix the height of the forehead support. By adjusting the forehead support, the height can be adjusted to support the forehead according to the face shape of different users, thereby improving the practicality of the instrument.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-5This utility model provides an embodiment of a polarized light skin detector, comprising an instrument body 1, which integrates various detection and display modules and provides a protective casing; a display screen 2 is provided on one side of the instrument body 1, which displays the detection results and interface information in real time; a detection mechanism 3 is provided on the rear inner wall of the instrument body 1, which captures the optical signals of the skin under polarized light irradiation and converts them into image data; a breathing light 4 is provided on the upper surface of the instrument body 1 near the opening, which indicates the detection status and helps the user to complete the correct positioning; a rotatable chin pad 5 is provided on the lower inner wall of the instrument body 1 near the opening, which supports the user's chin and can rotate freely according to head movements, improving detection comfort; a base 8 is provided directly below the instrument body 1, which provides stable support and is connected to the ground; an adjustment component is installed on the lower surface of the instrument body 1, which includes a connecting block 9 and a rotating plate 10. The slider 11 and the bidirectional lead screw 12 are fixedly connected to the upper surface of the connecting block 9 on the front side of the lower surface of the instrument body 1, and are used to support the adjustment structure. The outer wall of the rotating plate 10 is rotatably connected to the outer wall of the connecting block 9, and the power transmission is converted by the swing of the rotating plate 10. The slider 11 is rotatably connected to the outer wall of the rotating plate 10, and the slider 11 is used to achieve a small stroke displacement under the action of the rotating plate 10. The outer wall of the bidirectional lead screw 12 is threadedly connected to the inside of the slider 11. The bidirectional lead screw 12 can make the slider 11 move bidirectionally along the lead screw axis by rotating, thereby driving the overall lifting and adjustment of the instrument body 1. One end of the bidirectional lead screw 12 is rotatably connected to the inner wall of the base 8, and the other end of the bidirectional lead screw 12 is rotatably connected to the inside of the base 8 to ensure the transmission of driving force and stable support. The rear side of the lower surface of the instrument body 1 is fixedly connected to the hinge block 6, and the outer wall of the hinge block 6 is rotatably connected to the bracket 7. The bracket 7 is used to connect the base 8 and provide angle adjustment support. One side of the outer wall of the bracket 7 is fixedly connected to the outer wall of the base 8.

[0027] Specifically, by rotating the bidirectional lead screw 12, the user can cause the slider 11 to drive the rotating plate 10 and the connecting block 9 to move in tandem, thereby achieving precise adjustment of the lifting position of the instrument body 1 relative to the base 8; combined with the rotational connection between the hinge block 6 and the bracket 7, the tilt angle of the instrument can be further adjusted to meet the adaptation needs of different users' facial heights and postures, thereby improving detection accuracy and ease of use.

[0028] Reference Figures 1-5A sleeve 14 is fixedly connected to the top of the inner wall of the instrument body 1. The sleeve 14 forms a guide structure and restricts the movement path of the slide rod 15. The slide rod 15 is slidably connected inside the sleeve 14. The slide rod 15 can slide up and down inside the sleeve 14 to adjust the height of the forehead support 17. The forehead support 17 is fixedly connected to the lower end of the slide rod 15. The forehead support 17 is used to support the user's forehead to ensure head posture stability. A fixing box 18 is fixedly connected to one side of the outer wall of the sleeve 14. The fixing box 18 is used to install and position the T-shaped rod 19 and related locking components. The T-shaped rod 19 is slidably connected inside the fixing box 18. The T-shaped rod 19 can move linearly inside the fixing box 18 to advance and retract the locking block 21. A buckle plate 20 is rotatably connected to the outer wall of the T-shaped rod 19. When the buckle plate 20 rotates, it drives the T-shaped rod 19 to move to lock and release the locking block 21. A locking block 21 is fixedly connected to one end of the T-shaped rod 19. The locking block 21 is used to insert into the hole on the slide rod 15 to lock the position. A spring 22 is fitted onto the outer wall of the T-shaped rod 19. One end of the spring 22 abuts against the inner wall of the fixing box 18, providing elasticity to keep the T-shaped rod 19 in its initial position. The other end of the spring 22 abuts against the outer wall of the locking block 21, ensuring that the locking block 21 automatically returns to the locked position. A limit block 16 is fixedly connected to the upper end of the slide rod 15. The outer wall of the limit block 16 is slidably connected to the inner wall of the sleeve 14 to limit the movement limit position of the slide rod 15 and prevent it from sliding out. A through-hole device is provided on one side of the outer wall of the locking block 21. The locking block 21 is placed on the side wall of the sleeve 14 so that it can be inserted into the limiting hole of the slide rod 15 when locked; the outer wall of the locking block 21 is slidably connected to the hole opened inside the slide rod 15 to ensure a tight fit between the locking block 21 and the slide rod 15; one side of the outer wall of the buckle plate 20 abuts against one side of the outer wall of the fixing box 18, and the T-shaped rod 19 is driven to move by manual force; one end of the bidirectional screw 12 is fixedly connected to a knob 13, which is used by the user to manually rotate to drive the bidirectional screw 12 to adjust the height.

[0029] Specifically, by rotating the buckle plate 20, the user drives the T-shaped rod 19 to move and move the locking block 21 to limit or release the slide rod 15, allowing the slide rod 15 to slide up and down in the unlocked state, thereby adjusting the height of the forehead support 17 to adapt to the facial structure needs of different users; the spring 22 ensures that the locking block 21 can automatically reset after the buckle plate 20 is released to achieve quick locking, preventing the forehead support 17 from accidentally sliding during use; the sliding cooperation between the limiting block 16 and the sleeve 14 ensures that the slide rod 15 moves stably within its stroke range, effectively preventing damage caused by exceeding the structural stroke; the entire structure works together to improve head fixation during the testing process and ensure the stability and repeatability of the collected data.

[0030] Working principle: When the instrument is needed, the main body 1 integrates the overall structure and bears the load. A display screen 2 is located at the front to show detection data and image information. The detection mechanism 3 is installed on the rear inner wall of the main body 1 for image acquisition and analysis of facial skin. A breathing light 4 on the top provides visual cues to guide the user to align the instrument with the detection area. To improve user comfort, a rotatable chin pad 5 is provided at the bottom, which, together with the slide rod 15 and forehead support 17, positions the user's face. The up-and-down adjustment mechanism consists of a connecting block 9, a rotating plate 10, a slider 11, and a bidirectional lead screw 12. The device is constructed by rotating a knob 13 to drive a bidirectional lead screw 12 to rotate, thereby pushing a slider 11 and moving the main body 1 of the instrument up and down to accommodate users of different heights. The bracket 7 is connected to the hinge block 6 and is stably installed on the base 8 to provide support. The height of the forehead support 17 can be adjusted by sliding the slide rod 15 within the sleeve 14 and is limited by the limiting block 16. The T-shaped rod 19 slides within the fixing box 18, driving the locking block 21 to be positioned and providing a rebound force through the spring 22. The buckle plate 20 is used for fixed connection. The overall structure ensures accurate head positioning during use, thereby achieving a high-precision and high-stability face detection effect.
