Description

Technical Field

[0001] The utility model relates to the technical field of skin color testing, in particular to a device for testing overall skin color uniformity. Background Art

[0002] The overall skin tone uniformity test is a method to evaluate the appearance characteristics of the skin. By testing the uniformity of the skin tone, you can understand whether the skin has problems such as spots, dullness, uneven skin tone, etc. The skin tone reflects the health of the skin. For cosmetics companies, the skin tone uniformity test can help them understand the skin needs of different groups of people, so as to develop products that are more suitable for market demand.

[0003] In the prior art, when performing detection, the overall hair color uniformity detection device reduces the influence of the ambient brightness on the overall skin uniformity detection by using a fill light to improve the accuracy of the skin color uniformity detection.

[0004] However, when this overall skin color uniformity testing device detects the overall skin color uniformity, the ambient brightness and the fill light act together on the human skin. The fill light can only reduce the impact of the ambient brightness on the human skin, and the ambient brightness still has an impact on the overall uniformity detection of the human skin.

[0030] Example 1

[0031] This embodiment provides a device for testing the uniformity of skin color. Figure 1 As shown, it comprises a sleeve 1 for placing an arm, an air pump 2 is fixedly mounted on the outer wall of the sleeve 1, and a plurality of grooves 4 distributed in an annular manner are formed on the inner wall of the sleeve 1.

[0032] like Figure 2 and Figure 3 As shown, the inner wall of the sleeve 1 is provided with a closing component 3, and the closing component 3 includes a soft light cover 31, an LED lamp 33, an airbag 34 and an air guide tube 35. The soft light cover 31 is fixedly installed on the inner wall of the sleeve 1 and located in the middle position. A detection camera 6 is fixedly installed on the inner arc surface of the soft light cover 31. The detection camera 6 is used to detect the overall color uniformity. A yield groove 32 is opened between the sleeve 1 and the soft light cover 31. The LED lamp 33 is fixedly installed on the inner wall of the sleeve 1, and the light emission direction of the LED lamp 33 is toward the soft light cover 31.

[0033] Light is irradiated onto the soft light cover 31 through the clearance groove 32, and the soft light cover 31 diffuses the light to prevent the light from irradiating on the human arm to produce light spots and affect the accuracy of the overall skin uniformity test. A plurality of LED lights 33 are arranged and are distributed in a ring shape at the clearance groove 32 on the inner wall of the sleeve 1 to improve the lighting effect.

[0034] like Figure 3 As shown, two symmetrically arranged air bags 34 are fixedly installed on the inner wall of the sleeve 1, and the two air bags 34 are respectively located at the two ends of the soft light cover 31. The inner arc surface of the air bags 34 contacts the human arm. The air bags 34 adopt a circular ring structure. The two air bags 34 are interconnected through a pipeline. The other end of the air guide tube 35 is fixedly connected to the air bags 34, and the air guide tube 35 is fixedly installed at the end of the air pump 2. The air pump 2 transports gas into the air bags 34 through the air guide tube 35, so that the air bags 34 expand and press against the human skin, and a closed space is formed between the sleeve 1, the air bags 34 and the human hand.

[0035] In this embodiment, gas is passed into the airbag 34 to form a closed space between the sleeve 1, the airbag 34 and the human hand, thereby isolating the influence of the external environment brightness on the detection, and the LED lamp 33 is used to provide a light source for the detection. The LED lamp 33 emits a constant brightness and diffuses the light through the soft light cover 31 to avoid the formation of light spots that affect the overall skin color uniformity detection.

[0036] Example 2

[0037] Based on Example 1, this example proposes a device for testing overall skin color uniformity, such as Figure 2 and Figure 4 As shown, a pressure control assembly 5 is provided at the inner arc surface of the airbag 34, and the pressure control assembly 5 includes a docking barrel 51, a contact block 52, a top frame, a frame plate 56 and an electric shock switch 57. The docking barrel 51 is fixedly installed at the inner arc surface of the two airbags 34, and the inner wall of the docking barrel 51 is slidably connected to the contact block 52. A reset spring 54 is elastically connected between the top of the contact block 52 and the docking barrel 51. The reset spring 54 is sleeved on the rod body of the top rod 53, and the reset spring 54 is used to reset the contact block 52. The expansion of the airbag 34 drives the docking barrel 51 to move, so that the contact block 52 on the inner wall of the docking barrel 51 contacts the human arm, and the contact block 52 is subjected to force and compresses the reset spring 54 to generate displacement.

[0038] like Figure 4 As shown, a top frame is set on the top of the contact block 52, and the top frame includes a top rod 53 and a top plate 55. The top rod 53 passes through the docking barrel 51, and the bottom end of the top rod 53 is fixedly connected to the contact block 52. The top end of the top rod 53 slides left and right at the bottom of the top plate 55, and the top plate 55 and the frame plate 56 slide up and down at the make way groove 32. The frame plate 56 is fixedly installed on the top of the docking barrel 51, and the electric shock switch 57 is fixedly installed at the bottom center of the frame plate 56.

[0039] like Figure 4 As shown, two symmetrically arranged support plates are fixedly installed on the top of the docking barrel 51 , and the docking barrel 51 is fixedly connected to the frame plate 56 through the support plates. The two support plates are respectively located on the front and back sides of the top plate 55 .

[0040] When the docking barrel 51 moves with the airbag 34, the docking barrel 51 drives the frame 56 to move. During the movement, the distance between the frame 56 and the top plate 55 remains unchanged. When the contact block 52 is squeezed and displaced after contacting the person's arm, the contact block 52 uses the push rod 53 to drive the top plate 55 to move upward, and the frame 56 contacts the electric shock switch 57. The electric shock switch 57 is electrically connected to the air pump 2 through the controller. At this time, the air pump 2 stops filling gas into the airbag 34 to prevent the airbag 34 from over-expanding and squeezing the person's arm, causing the arm to become congested and discolored.

[0041] The electric shock switch 57 is directly above the center of the top plate 55. Since the sleeve 1 is sleeved on the human arm, from the palm to the shoulder, the human arm gradually thickens. Therefore, the positions of the two air bags 34 inside the sleeve 1 in contact with the arm are different, and the sizes of the two air bags 34 that need to expand are different. When a contact block 52 touches the human arm, it pushes one end of the top plate 55 upward. Since the electric shock switch 57 is directly above the center of the top plate 55, when one end of the top plate 55 moves upward, the other end remains in place, and the middle position of the top plate 55 cannot touch the electric shock switch 57. When both contact blocks 52 touch the human arm, the middle part of the top plate 55 presses the electric shock switch 57, and the air pump 2 stops filling the air bags 34 with gas.

[0042] In this embodiment, when both contact blocks 52 touch the human arm, both ends of the top plate 55 move upward, so that the middle part of the top plate 55 presses the electric shock switch 57, and the air pump 2 stops filling the air bags 34 with gas. At this time, both air bags 34 are in contact with the human arm, forming a sealed space, thus achieving the effect of adapting to arms of different thicknesses.

[0043] The above specific embodiments are only several alternative embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
