Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1 and Figure 2, the schematic diagram of the dynamic detector of sweating volume, the air pump 2 is fixedly installed in a housing 1, and the air pump 2 is connected to a trachea 3 of Φ6mm and a thickness of 1.0mm made of transparent soft silicone material, and the trachea 3 is installed The flow meter 4 and the gas pipe 3 protrude from the outlet of the flow meter 4 and are connected to the inlet of the regulating valve 5, which can be fixed on the housing 1, and the flow regulating outlet of the regulating valve 5 continues to connect to the gas pipe 3. The housing 1 is processed with an air outlet, and the air pipe 3 protrudes out of the housing 1 through the air outlet, and is connected with the sweat detection probe 11 .

The cooling fin 19 is fixedly installed inside the housing 1, the condensation box 6 is fixedly installed on the cooling fin 19, and the cooling fin 20 is installed between the cooling fin 19 and the condensation box 6, so that the cooling fin 20 cools on one side and generates heat on the other side, and its hot surface is tight. Paste the heat sink 19, and the cold surface is close to the condensation box 20.

As shown in the schematic diagram of the condensation box in FIG. 3 , the main body of the condensation box 6 is a rectangular casing 7 , and an air inlet 8 and an air outlet 9 are opened on the side of the casing 7 . Mill out some rectangular parallelepiped columns 10 inside the rectangular housing 7 , that is, the rectangular parallelepiped columns are integral with the entire rectangular housing 7 . In this embodiment, the rectangular housing 7 is provided with 4 rows and 7 columns with a total of 28 rectangular parallelepiped columns 10 of 2mm×8mm×19mm. These rectangular parallelepiped columns 10 can fully condense moisture in the air.

As shown in Fig. 4a, Fig. 4b and Fig. 4c, the sweat detection probe 11 is composed of two parts: a fixedly connected disc-shaped structure 12 and a circular cover-shaped structure 16 on one side thereof. The disc-shaped structure 12 is made of Φ45mm nylon material, the cover-like structure 16 is made of nylon material with a thickness of 5mm, and the disc-shaped structure 12 and cover-like structure 16 are made of stainless steel Screw secure connection.

Figures 4d and 4e show a disc-shaped structure 12, with a curved channel 13 on one side of the disc surface. In this embodiment, the channel 13 is an S-shaped channel. Two air holes 15 are processed at the bottom of the channel 13, and two grooves 14 are processed on the disk surface on the other side. The above-mentioned two air holes 15 are respectively located in the two grooves 14, so that the channel 13 passes through the The two air holes 15 communicate with the two grooves 14 respectively.

As shown in Figure 4f and Figure 4g, another part of the circular cover-like structure 16 that constitutes the probe 11, the inner side of the cover-like structure 16 (the side that contacts the disc surface of the disc-shaped structure 12 with the groove 14) is fixedly installed with Two humidity sensors 17, each humidity sensor 17 is just located in the groove 14 of disc-shaped structure 12 respectively; The trachea 3 is connected to the trachea connector 18 .

When working, firstly, the probe 11 is in close contact with the skin surface of the human body, and the cooling fin 19 and the cooling fin 20 are activated to keep the cooling fin 20 at about the dew point, and the air pump 2 is turned on, and the air passes through the cooling fin 19, the cooling fin 20, and then passes through the The air inlet 8 of the condensation box 6 enters the condensation box 6, and comes out through the air outlet 9 on it, so that the air is condensed and dried to remove moisture, and the air after being condensed and dried enters the air pump 2, and passes through the air pipe 3 connected to the air pump 2. The gas flows to the gas outlet of the casing 1 and then enters the probe 11 through the gas outlet. Since the probe 11 is designed with a gas pipe joint 18, the gas enters the inside of the probe 11 through the joint 18, contacts the humidity sensor chip 17 corresponding to the inside of the cover structure 16 of the joint 18, enters the channel 13 through the air hole 15, and passes through the air hole 15. The channel 13 flows through the skin surface of the human body, takes away the sweat on the human body surface in gaseous form, passes through another humidity sensor 17 , and finally discharges the probe 11 through the air hole 15 . The reason why the cooling fins 19, the cooling fins 20 and the condensation box 6 are used to obtain the condensed gas is to ensure that the air humidity of the air inlet is low so that the sweat can be fully absorbed. In this embodiment, a flow meter 4 and a regulating valve 5 are designed, so that the gas flow rate can be known and controlled in real time.

The above-mentioned embodiments are only used to illustrate the present invention, not to limit the present invention, so any changes in numerical values or replacement of equivalent elements should still fall within the scope of the present invention.
