This invention relates to a high-efficiency fog collector unaffected by fog flow direction and its manufacturing method. First, a superhydrophobic coating is formed on the surface of a copper sheet. Then, patterns are drawn on the copper sheet using a laser as punctuation marks. After electroplating, multiple superhydrophilic protrusions are formed. Finally, a uniquely shaped umbrella-like structure is formed through plastic stamping. The fog collector provided by this invention not only has high fog collection efficiency and adapts to any fog flow direction, but also uses abundant and readily available raw materials. Furthermore, the manufacturing process is simple, time-saving, and highly efficient, providing new ideas for the design of future high-efficiency fog collectors.

Even when the fan is not installed correctly, the fog collection device of the present invention can prevent the motor shaft of the filter motor from seizing with the shaft insertion hole of the filter, and can prevent the filter from contacting and breaking with other components, and can maintain the exhaust function based on the fan. The fog collection device includes: a fan (10) that is rotated by a fan motor (11), and a filter (12) that is installed by inserting the motor shaft (13a) of the filter motor (13) into the shaft insertion hole (12a). When the operation is started, the filter installation status determination unit (25) determines the installation status of the filter (12). If the filter installation status determination unit (25) determines that the filter (12) is not installed correctly, the control unit (23) prevents the filter (12) from rotating by the filter motor (13) and allows the fan (10) to continue rotating by the fan motor (11).

The invention discloses a design method of a liquid-like surface mist collection active synergistic device based on a pyroelectric effect. The method comprises the following steps: step 1, pretreating a pyroelectric wafer material; step 2, performing liquid phase modification on the pyroelectric wafer; step 3, covering a PDMS micro-pattern and pasting a film; step 4, performing hydrophilic patterning on the pyroelectric wafer; and step 5, combining fog collecting devices. The fog collection active synergistic device designed by the method can realize active collection of fog on the surface by virtue of the pyroelectric effect of the pyroelectric material, the fog is accelerated to be condensed into small water drops on the surface, the small water drops are converged into large water drops under the low-viscosity effect of the liquid-like surface, and the liquid drops quickly slide off to be exposed out of the smooth surface after being converged to a certain degree, so that the fog collection effect is improved. Water mist condensed small water drops are collected again on the surface under the pyroelectric action, and efficient mist collection is achieved in cycles. The active synergistic device for fog collection is simple in preparation process, small in finished product, free of a large external device, easy to carry and capable of being carried and used.
