In the embodiment, the counter electrode 140 and the discharge electrode 120 are spaced apart from each other, and the second tip portions 142 and the first tip portions 121 are opposite to each other. In other words, the counter electrode 140 and the discharge electrode 120 are spaced apart from and overlap with each other. A spacing distance between the counter electrode 140 and the discharge electrode 120 may be appropriately adjusted according to actual requirements. As long as the counter electrode 140 and the discharge electrode 120 are separated from each other and meet high voltage electrical safety considerations, the same falls within the protection scope of the disclosure.
In the embodiment, the counter electrode 140 is connected to the base 150. The material of the base 150 may include an insulating material. For example, the base 150 may be made of an insulating material. An inner space of the base 150 is configured to accommodate the discharge electrode 120, and the base 150 is disposed on the heat sink 130. Here, the heat sink 130 is, for example, a heat sink fin, but not limited thereto.
In the embodiment, the base 150 is configured to separate the discharge electrode 120 and the counter electrode 140. For example, the base 150 includes a side wall 151. The side wall 151 surrounds the discharge electrode 120, and the side wall 151 has a top portion 1511 away from the heat sink 130. The counter electrode 140 includes a plate body 143, and the plate body 143 is connected to the top portion 1511.
In the embodiment, the discharge electrode 120 includes an annular body 122. In other words, the discharge electrode 120 is in a crown shape. In other embodiments, the body of the discharge electrode 120 may also be in a square shape or a polygonal shape, but not limited thereto. The first tip portions 121 extend and protrude from a side of the annular body 122 away from the cooling chip 110 toward the counter electrode 140. The first tip portions 121 are integrated with the annular body 122.
In the embodiment, the cooling chip 110 is located between the heat sink 130 and the discharge electrode 120. Current is supplied to the cooling chip 110 through conductive lines P3 and P4, and the discharge electrode 120 is cooled through the cooling chip 110. Therefore, condensed water is generated on a surface of the discharge electrode 120, and more moisture present in the air in the base 150 may be collected through the first tip portions 121. In the embodiment, the cooling chip 110 for cooling the discharge electrode 120 is used as a water supply element for supplying water for atomization to the discharge electrode 120, but not limited thereto.
In the embodiment, the counter electrode 140 has a hole 141 located on the plate body 143, and the second tip portions 142 are arranged along an edge of the hole 141 and extend and protrude toward the discharge electrode 120. The second tip portions 142 are integrated with the plate body 143.
In the embodiment, the hole 141 has a first diameter D1, the annular body 122 has a second diameter D2, and the first diameter D1 is greater than the second diameter D2. Water mist generated by the discharge electrode 120 flows to the outside of the base 150 through the hole 141.
For details, please refer to
In the embodiment, the first tip portions 121 provide the high voltage from the single voltage application unit 21. For example, the discharge electrode 120 holding water in the first tip portions 121 is adapted to be applied with the high voltage by the voltage application unit 21, so that charges may be concentrated on the first tip portions 121 of the discharge electrode 120 as a negative electrode, and the water held on the first tip portions 121 is repeatedly subjected to Rayleigh fission generated by a large amount of energy, which generates a large number of charged water particles. The charged water particles move toward the counter electrode 140 and then pass through the holes 141 of the counter electrode 140 to be discharged to the outside.
Under the above configuration, the first tip portions 121 may collect more water droplets, so that the amount sprayed toward the second tip portions 142 is increased, which can increase the amount of liquid atomization.
Other embodiments are listed below for illustration. It must be noted here that the following embodiment continues to use the reference numerals and some content of the previous embodiment, wherein the same numerals are adopted to represent the same or similar elements, and the description of the same technical content is omitted. For the description of the omitted part, reference may be made to the previous embodiment, which will not be repeated in the following embodiment.
In the embodiment, the discharge electrode 120B includes a rod-shaped body 122B. The rod-shaped body 122B and the annular body 122 shown on
A high voltage for electrostatic atomization is applied between the discharge electrode 120B and the counter electrode 140 through the voltage application unit 21. The discharge electrode 120B holding water in the first tip portions 121B is adapted to be applied with the high voltage by the voltage application unit 21, so that charges may be concentrated on the first tip portions 121B of the discharge electrode 120B as a negative electrode, and the water held on the first tip portions 121B is repeatedly subjected to Rayleigh fission generated by a large amount of energy, which generates a large number of charged water particles. The charged water particles move toward the counter electrode 140 and then pass through the hole 141 of the counter electrode 140 to be discharged to the outside.
In this way, the first tip portions 121B may collect more water droplets, so that the amount sprayed toward the second tip portions 142 is increased, which can increase the amount of liquid atomization.
In summary, in the atomization device of the disclosure, the discharge electrode includes the first tip portions. The counter electrode includes the second tip portions. More water droplets may be collected through the first tip portions, so that the amount sprayed toward the second tip portions is increased, which can increase the amount of liquid atomization.
