specific Embodiment approach 1

[0023] Specific implementation mode one: combine figure 1 , figure 2 and image 3 Describe this embodiment. The microfluidic air water intake device described in this embodiment includes a mechanical unit and an electrical control unit. The mechanical unit includes a one-way valve 1, an air intake channel 2, a hygroscopic material 3, a heating device 4, Hygroscopic cavity 5 and condensation flow channel 6;

[0024] The air inlet of the air intake channel 2 is provided with a one-way valve 1, the air outlet of the air intake channel 2 communicates with the air inlet of the moisture absorption chamber 5, the moisture absorption material 3 is fully arranged in the moisture absorption chamber 5, and the heating device 4 is used for Heat the moisture absorption chamber 5, and the air outlet of the moisture absorption chamber 5 communicates with the air inlet of the condensation flow channel 6;

[0025] The one-way valve 1 is used to control the air entering the intake air passa...

specific Embodiment approach 2

[0031] Embodiment 2: This embodiment is a further description of the microfluidic air water intake device described in Embodiment 1. The condensation channel 6 is serpentine or spiral.

specific Embodiment approach 3

[0032] Embodiment 3: This embodiment is a further description of the microfluidic air water intake device described in Embodiment 1. The timing control circuit 9 uses a 555 timer.

[0033] In this embodiment, the adsorption time and heating time are controlled by a 555 timer, both of which are adjustable from 1 to 200 minutes, and the time adjustment is controlled by two sliding rheostats, which automatically realize the cycle of adsorption and heating. When the temperature in the moisture absorption chamber 5 is greater than the preset threshold value of the sensor, the temperature sensor 5 outputs a low-level signal, which is compared with the reference voltage of the voltage comparator, and outputs a low level to stop heating and maintain the temperature Does not rise; when the temperature in the moisture absorption chamber 5 is lower than the low preset threshold, the level signal output by the temperature sensor will output a high level after passing through the voltage co...

Description

technical field [0001] The invention belongs to the field of air water intake and the application field of microfluid control, in particular to a micro water intake device. Background technique [0002] At present, there are mainly two types of mature air water intake devices in the market: adsorption type and condensation type. [0003] The adsorption type is a water intake device that uses adsorption materials to absorb water vapor in the air, and then heats and desorbs the materials to release water. The performance of the adsorption water intake device is affected by the performance of the adsorption material, and the water intake efficiency is low. [0004] The condensing type is a water intake device that uses the principle of refrigeration condensation to reduce the air temperature through a refrigerator, so that the water vapor content in the air reaches a saturated state, thereby separating out water droplets, and then collecting water droplets. [0005] The refri...
