[0043] Now, reference will be made in detail to the exemplary embodiments of the present invention. Examples of the exemplary embodiments are illustrated in the accompanying drawings. Whenever possible, the same reference numerals are used in the drawings and the description to denote the same or similar parts.

[0044] Figure 1 is a perspective schematic view of an atomizing device according to an embodiment of the present invention. Figure 2 is Figure 1 a cross-sectional schematic view of the atomizing device. Please refer to Figure 1 and Figure 2 , the atomizing device 100 of the present embodiment includes a thermoelectric cooling chip 110 (Thermoelectric Cooling Module, TEC), a discharge electrode 120, a heat dissipation member 130, a counter electrode 140, and a base 150. The discharge electrode 120 includes an opposite first side S1 and a second side S2. The second side S2 of the discharge electrode 120 is connected to the thermoelectric cooling chip 110. The discharge electrode 120 includes a plurality of first tips 121 located on the first side S1. The counter electrode 140 includes a plurality of second tips 142.

[0045] In the present embodiment, the counter electrode 140 and the discharge electrode 120 are arranged at intervals, and the plurality of second tips 142 and the plurality of first tips 121 are opposite to each other. In other words, the counter electrode 140 and the discharge electrode 120 are stacked on top of each other at intervals. The interval distance between the counter electrode 140 and the discharge electrode 120 can be adjusted appropriately according to actual needs, as long as the counter electrode 140 and the discharge electrode 120 are separated from each other and meet the high-voltage electricity safety considerations, they are all within the scope of protection of the present application.

[0046] In this embodiment, the counter electrode 140 is connected to the base 150. The base 150 is made of an insulating material. The inner space of the base 150 is used 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 is not limited thereto.

[0047] In this embodiment, the base 150 is used to separate the discharge electrode 120 and the counter electrode 140. For example, the base 150 includes a side wall 151 that surrounds the discharge electrode 120, and the side wall 151 has a top 1511 that is 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 1511.

[0048] In this embodiment, the discharge electrode 120 includes an annular body 122. That is to say, the discharge electrode 120 is coronal. In other embodiments, the body of the discharge electrode 120 can also be square, polygonal, etc., and is not limited thereto. A plurality of first tips 121 extend and protrude from the side of the annular body 122 away from the refrigeration chip 110 toward the counter electrode 140. The plurality of first tips 121 and the annular body 122 are integral.

[0049] In this embodiment, the refrigeration chip 110 is located between the heat sink 130 and the discharge electrode 120. By supplying current to the refrigeration chip 110 through the wires P3 and P4, the discharge electrode 120 will be cooled by the refrigeration chip 110. Therefore, condensed water is generated on the surface of the discharge electrode 120, and more moisture existing in the air in the base 150 can be gathered through the plurality of first tips 121. In this embodiment, the refrigeration chip 110 used to cool the discharge electrode 120 serves as a water supply element for supplying water for atomization to the discharge electrode 120, but is not limited thereto.

[0050] Figure 4 is Figure 1 A top view schematic diagram of the atomization device. Figure 3 is Figure 1 A partial perspective schematic diagram of the atomization device. Please refer to Figure 3 and Figure 4 In this embodiment, the number of the plurality of first tips 121 is even (schematically shown as eight) and they are arranged in pairs opposite to each other, but is not limited thereto. The number of the plurality of second tips 142 is even (schematically shown as eight) and they are arranged in pairs opposite to each other, but is not limited thereto. Here, the number of the plurality of first tips 121 is equal to the number of the plurality of second tips 142, but is not limited thereto.

[0051] In this embodiment, the counter electrode 140 has a through hole 141 located in the plate body 143, and a plurality of second tips 142 are arranged along the edge of the through hole 141 and extend and protrude toward the discharge electrode 120. The plurality of second tips 142 and the plate body 143 are integral.

[0052] In this embodiment, the through-hole 141 has a first diameter D1, and the annular body 122 has a second diameter D2, and the first diameter D1 is greater than the second diameter D2. The water mist generated by the discharge electrode 120 reaches the outside of the base 150 through the through-hole 141.

[0053] Specifically, please refer to Figure 2 , in this embodiment, one end of the wire P2 is connected to the discharge electrode 120 inside the base 150, and the other end of the wire P2 is connected to the voltage application unit 21 arranged outside the base 150. One end of the wire P1 is connected to the counter electrode 140 on the base 150, and the other end of the wire P1 is connected to the voltage application unit 21 arranged outside the base 150. The voltage application unit 21 applies a high voltage for electrostatic atomization between the discharge electrode 120 and the counter electrode 140.

[0054] In this embodiment, a plurality of first tips 121 are supplied with high voltage by a single voltage application unit 21. For example, the discharge electrode 120 holding water in the first tip 121 is adapted to be applied with high voltage by the voltage application unit 21, so that charges can be concentrated on the first tip 121 of the discharge electrode 120 as the negative electrode, and the water held on the first tip 121 will repeatedly undergo Rayleigh fission generated by a large amount of energy. This will generate a large number of charged water particles. The charged water particles move towards the counter electrode 140 and then are discharged outwards through the through-hole 141 of the counter electrode 140.

[0055] Under the above configuration, a plurality of first tips 121 can collect more water droplets, increasing the amount sprayed towards the plurality of second tips 142 and increasing the liquid atomization amount.

[0056] Other embodiments will be listed below for illustration. It must be noted here that the following embodiments follow the component numbers and some contents of the foregoing embodiments, where the same numbers are used to represent the same or similar components, and the description of the same technical content is omitted. For the description of the omitted parts, reference can be made to the foregoing embodiments, and the following embodiments will not be repeated.

[0057] Figure 5 is a partial perspective view of an atomizing device according to another embodiment of the present invention. Figure 6 is Figure 5 a cross-sectional view of the atomizing device. Figure 7 is Figure 5 a top view of the atomizing device. Please refer to Figures 5 to 7 , in this embodiment, the atomizing device 100B is slightly different from Figure 4 the atomizing device 100, and the main difference lies in: the form of the discharge electrode 120B.

[0058] In this embodiment, the discharge electrode 120B includes a rod-shaped body 122B. A plurality of first tips 121B extend and protrude from one end of the rod-shaped body 122B away from the refrigeration wafer 110 toward the counter electrode 140. The plurality of first tips 121B and the rod-shaped body 122B are integral. Such a design can achieve the effect of reducing the overall volume.

[0059] A high voltage for electrostatic atomization is applied between the discharge electrode 120B and the counter electrode 140 by a voltage application unit 21. The discharge electrode 120B holding water in the first tips 121B is adapted to be applied with a high voltage by the voltage application unit 21, so that charges can be concentrated on the first tips 121B of the discharge electrode 120B as the negative electrode, and the water held on the first tips 121B will repeatedly undergo Rayleigh fission generated by a large amount of energy. This will generate a large number of charged water particles. The charged water particles move toward the counter electrode 140 and then are discharged outward through the holes 141 of the counter electrode 140.

[0060] In this way, the plurality of first tips 121B can collect more water droplets, increasing the amount sprayed toward the plurality of second tips 142 and increasing the liquid atomization amount.

[0061] In summary, in the atomization device of the present invention, the discharge electrode includes a plurality of first tips. The counter electrode includes a plurality of second tips. By means of the plurality of first tips, more water droplets can be collected, increasing the amount sprayed toward the plurality of second tips and increasing the liquid atomization amount.
