[0023] Please refer to Figures 1-5The utility model provides a kind of skin moisture evaporation rate tester, including tester body 1, measurement cavity 2 is provided on tester body 1, humidity sensor 3 is installed in tester body 1, the end of humidity sensor 3 extends into measurement cavity 2, when the end of measurement cavity 2 is pressed on the skin of tester, measurement cavity 2 will form closed cavity between skin, skin evaporation moisture will gather therein, at this time, the end of humidity sensor 3 is located in the inside of the cavity, after the humidity sensor 3 is opened by power switch, humidity sensor 3 can gather humidity information in the cavity, data processing unit 4 is provided in the inside of tester body 1, data processing unit 4 is single-chip microcontroller and single chip, it can calculate the moisture evaporation rate of the skin of measured area according to the change of humidity information gathered by humidity sensor 3, the humidity information measured and skin moisture evaporation rate are displayed on the display of tester body 1 for user to view, two sides of tester body 1 are connected with bandage 5, and the end of two groups of bandage 5 can be connected together by magic tape or lock catch, so that user can bind tester body 1 on wrist by two groups of bandage 5, the utility model also includes a group of threaded cover 6, measurement cavity 2 is provided with threaded port 7 screwing with threaded cover 6, installation groove 8 is provided in the inside of threaded cover 6, water-absorbing tampon 9 is embedded in the inside of installation groove 8, threaded cover 6 can be rotated and tightened on threaded port 7, so that the end of measurement cavity 2 can be covered, at this time, one end of water-absorbing tampon 9 will extend into measurement cavity 2 and be attached to the inner wall of measurement cavity 2, and the end of water-absorbing tampon 9 is provided with containing groove 10, when one end of water-absorbing tampon 9 extends into measurement cavity 2, containing groove 10 will cover the end surface of humidity sensor 3.

[0024] In use, the user binds the test instrument body 1 on the wrist through the strap 5, which is convenient for carrying the test instrument body 1. When it is needed to measure the water evaporation rate on the skin, the user only needs to press the end of the measuring cavity 2 on the part of the tester's skin which needs to be tested and start the power switch. The humidity sensor 3 collects the humidity information in the cavity formed between the measuring cavity 2 and the skin, and calculates the change of the humidity information collected by the humidity sensor 3 through the data processing unit 4 to calculate the water evaporation rate of the measured area of the skin. The measured humidity information and the water evaporation rate of the skin are displayed on the display of the test instrument body 1 for the user to view. After the test is completed and the power switch is turned off, the user can tighten the threaded cover 6 on the threaded port 7. At this time, the threaded cover 6 can cover the end of the measuring cavity 2 to avoid the moisture from the outside entering the measuring cavity 2. Meanwhile, one end of the water-absorbing cotton plug 9 extends into the measuring cavity 2 and is attached to the inner wall of the measuring cavity 2, which can absorb the moisture attached to the inner wall of the measuring cavity 2. The accommodation groove 10 at the end of the water-absorbing cotton plug 9 covers the end surface of the humidity sensor 3, so as to absorb the moisture attached to the end of the humidity sensor 3. When the water evaporation rate of the skin is measured subsequently, the moisture attached to the inner wall of the measuring cavity 2 and the end of the humidity sensor 3 can be avoided to affect the accuracy of the measurement data.

[0025] Further, please refer to Figure 5 , the inner wall of the mounting groove 8 is provided with a rubber snap ring 11, and the surface of the water-absorbing cotton plug 9 is provided with a clamping groove 12 for the rubber snap ring 11 to extend into. When the end of the water-absorbing cotton plug 9 is inserted into the inside of the mounting groove 8, the rubber snap ring 11 on the inner wall of the mounting groove 8 extends into the clamping groove 12 on the surface of the water-absorbing cotton plug 9. At this time, under the action of the rubber snap ring 11 and the clamping groove 12, the end of the water-absorbing cotton plug 9 can be stably embedded in the mounting groove 8 inside the threaded cover 6 and is not easy to fall off. The user can pull the water-absorbing cotton plug 9 out of the inside of the mounting groove 8 with force, so as to separate the rubber snap ring 11 from the clamping groove 12, thereby enabling the water-absorbing cotton plug 9 inside the threaded cover 6 to be replaced.

The connecting band 13, the clamping ring 14 and the annular groove 15 can connect the threaded cover 6 to one end of the connecting band 13. When the threaded cover 6 is rotated and removed from the end of the measuring cavity 2, the threaded cover 6 can be avoided from being lost. In addition, since the clamping ring 14 is movably sleeved outside the annular groove 15 on the surface of the threaded cover 6, the threaded cover 6 is connected to the end position of the connecting band 13, so as not to affect the rotation of the threaded cover 6.

[0027] Further, referring to Figure 2 and Figure 3 , the end surface of the measuring cavity 2 is provided with a sealing ring 16 made of silicone rubber, which can tightly contact the skin when the end of the measuring cavity 2 is covered on the user's skin, thereby increasing the sealing of the joint between the measuring cavity 2 and the user's skin, avoiding the moisture on the skin from seeping out to the outside of the measuring cavity 2, and ensuring the accuracy of the measurement results.

[0028] Further, referring to Figure 1 and Figure 2 , the edge of the tester body 1 is a rounded structure, which can avoid the edge of the tester body 1 from leaving indentations on the wrist when the tester body 1 is bound on the wrist by the strap 5, thereby ensuring the comfort of the user.

[0029] Further, referring to Figure 4 , the threaded cap 6 is provided with anti-skid strips 17, which are distributed in several groups around the outer surface of the threaded cap 6, and which can increase the frictional resistance between the user's hand and the surface of the tester body 1 when holding the threaded cap 6, thereby facilitating the user to rotate and twist the threaded cap 6 with less effort.

[0030] The above is only the preferred embodiment of the present application, and is not used to limit the present application.
