a skin tester

Abstract

The invention discloses a skin testing device. The skin testing device comprises a machine body and a testing head arranged on the upper end of the machine body, wherein the testing head comprises a testing end face, the testing end face is provided with sensors, the sensors comprise an inner sensor and an outer sensor, the inner sensor and the outer sensor have the same center shaft, and at least part of the outer sensor surrounds the periphery of the inner sensor. The skin testing device has the advantages that the design is elaborate, the structure is reasonable, the operation is convenient, various physiological parameters of the skin water content and the skin oil content can be measured at the same time through the arrangement of the various sensors, through the reasonable arrangement of the shapes of the sensors, the two sensors are fully combined together to enable the two sensors to have an overlapped or partially overlapped detecting area at the same time, the space is reasonably used through the arrangement, the area of the testing head is made to be minimum to meet the testing requirements of areas including the hands and the face, and meanwhile the testing precision can be guaranteed.

Description

technical field [0001] The invention relates to a tester, especially a skin tester with multiple sensors. Background technique [0002] With the development of the economy and the continuous improvement of people's living standards, people's awareness of health care is constantly strengthening. Therefore, with the rapid advancement of science and technology, various types of skin care equipment have entered the market one after another. [0003] At present, the portable skin testers on the market either have only one sensor on each probe. If various physiological parameters of the skin are to be tested, the test heads need to be replaced frequently, which greatly reduces the test efficiency and the user experience is not good; or , there are multiple sensors on one test head, but the volume of the test head is relatively large, but the skin of the human body, especially the skin of the face and hands is not large and is curved, and there is no large flat surface, so use Whe...

Problems solved by technology

[0003] At present, the portable skin testers on the market either have only one sensor on each probe. If various physiological parameters of the skin are to be tested, the test heads need to be replaced frequently, which greatly reduces the test efficiency and the user experience is not good; or , there are multiple sensors on one test head, but the volume of the test head is relatively large, but the skin of the human body, especially the skin of the face and hands is not large and is curved, and there is no large flat surface, so use When the large test head tests the face and hands, the data error is large, which makes the test accuracy not high. Therefore, it is urgent to study a skin tester with exquisite design, simple operation, reliable performance and various functions.
