[Figure 5] This is a schematic local perspective view of an atomizing device according to another embodiment of the present invention. [Figure 6] Figure 5 is a schematic cross-sectional view of the atomizing device. [Figure 7] Figure 5 is a schematic top view of the atomizing device. [Modes for carrying out the invention]

[0017] Figure 1 is a schematic three-dimensional view of an atomizing device according to one embodiment of the present invention. Figure 2 is a schematic cross-sectional view of the atomizing device of Figure 1. Referring to Figures 1 and 2, the atomizing device 100 in this embodiment includes a cooling tip 110 (Thermoelectric Cooling Module, TEC), a discharge electrode 120, a heat sink 130, a counter electrode 140, and a base 150. The discharge electrode 120 includes opposing first side S1 and second side S2. The second side S2 of the discharge electrode 120 is connected to the cooling tip 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.

[0018] In this embodiment, the counter electrode 140 is positioned at a distance from the discharge electrode 120, and the plurality of second tips 142 face each other, with the plurality of first tips 121 facing each other. In other words, the counter electrode 140 and the discharge electrode 120 are stacked at a distance from each other. The distance between the counter electrode 140 and the discharge electrode 120 can be appropriately adjusted as needed, and as long as the counter electrode 140 and the discharge electrode 120 are separated from each other and comply with high-voltage electrical safety considerations, they are all within the scope that the present invention seeks to protect.

[0019] In this embodiment, the counter electrode 140 is connected to a base 150. The base 150 is made of an insulating material. The internal space of the base 150 is used to accommodate the discharge electrode 120, and the base 150 is placed on a heat sink 130. Here, the heat sink 130 is, for example, a heat dissipation fin, but is not limited thereto.

[0020] 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. The side wall 151 surrounds the discharge electrode 120 and has an upper portion 1511 that is separated from the heat sink 130. The counter electrode 140 includes a plate body 143, and the plate body 143 is connected to the upper portion 1511.

[0021] In this embodiment, the discharge electrode 120 includes an annular main body 122. That is, the discharge electrode 120 is coronal, but in other embodiments, the main body of the discharge electrode 120 may be square or polygonal and is not limited thereto. The plurality of first tips 121 extend and protrude from a side of the annular main body 122 away from the cooling chip 110 toward the counter electrode 140. The plurality of first tips 121 and the annular main body 122 are integral.

[0022] In this 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 via conductive wires P3 and P4, and the discharge electrode 120 is cooled via the cooling chip 110. Therefore, condensed water is generated on the surface of the discharge electrode 120, and more moisture present in the air within the base 150 can be collected via the plurality of first tips 121. In this embodiment, the cooling chip 110 used to cool the discharge electrode 120 is used as a supply element for supplying atomizing water to the discharge electrode 120, but is not limited thereto.

[0023] FIG. 4 is a schematic top view of the atomizing device of FIG. 1. FIG. 3 is a schematic partial perspective view of the atomizing device of FIG. 1. Referring to FIGS. 3 and 4, in this embodiment, the number of the plurality of first tips 121 is an even number (schematically shown as 8) and they are installed opposite to each other, but is not limited thereto. The number of the plurality of second tips 142 is an even number (schematically shown as 8) and they are installed 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.

[0024] In this embodiment, the counter electrode 140 has a hole 141 located in the plate body 143. A plurality of second tips 142 are arranged along the edge of the hole 141 and extend and protrude toward the discharge electrode 120. The plurality of second tips 142 and the plate body 143 are integral.

[0025] In this embodiment, the hole 141 has a first diameter D1, and the annular body 122 has a second diameter D2, with the first diameter D1 being larger than the second diameter D2. The water mist generated by the discharge electrode 120 reaches the outside of the base 150 through the hole 141.

[0026] More specifically, referring to Figure 2, in this embodiment, one end of the conductor P2 is connected to the discharge electrode 120 inside the base 150, and the other end of the conductor P2 is connected to a voltage application unit 21 located outside the base 150. One end of the conductor P1 is connected to the counter electrode 140 on the base 150, and the other end of the conductor P1 is connected to a voltage application unit 21 located 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.

[0027] In this embodiment, multiple first tips 121 are supplied with a high voltage by a single voltage application unit 21. For example, a discharge electrode 120 holding water at the first tips 121 is configured to have a high voltage applied by the voltage application unit 21, thereby concentrating the charge with the first tips 121 of the discharge electrode 120 as the negative electrode. The water held at the first tips 121 undergoes repeated Rayleigh splitting caused by the large energy. This generates a large amount of charged water particles. The charged water particles move toward the counter electrode 140 and are then discharged to the outside through the holes 141 in the counter electrode 140.

[0028] With this arrangement, the multiple first tips 121 can collect more water droplets, thereby increasing the amount of spray directed to the multiple second tips 142 and increasing the amount of liquid atomized.

[0029] Figure 5 is a schematic local perspective view of an atomizing device according to another embodiment of the present invention. Figure 6 is a schematic cross-sectional view of the atomizing device of Figure 5. Figure 7 is a schematic top view of the atomizing device of Figure 5. Referring to Figures 5 to 7, in this embodiment, the atomizing device 100B differs slightly from the atomizing device 100 of Figure 4, the main difference being the type of discharge electrode 120B.

[0030] In this embodiment, the discharge electrode 120B includes a rod-shaped body 122B. Multiple first tips 121B extend and protrude from one end of the rod-shaped body 122B away from the cooling tip 110 toward the counter electrode 140. The multiple first tips 121B and the rod-shaped body 122B are integrated. This design has the effect of reducing the overall volume.

[0031] A high voltage for electrostatic atomization is applied between the discharge electrode 120B and the counter electrode 140 via the voltage application unit 21. The discharge electrode 120B, which holds water at its first tip 121B, is configured to have a high voltage applied to it by the voltage application unit 21. This allows the charge to be concentrated with the first tip 121B of the discharge electrode 120B acting as the negative electrode, and the water held at the first tip 121B repeatedly undergoes Rayleigh splitting caused by the large energy. This generates a large amount of charged water particles. The charged water particles move towards the counter electrode 140 and are then discharged to the outside through the holes 141 in the counter electrode 140.

[0032] In this way, the multiple first tips 121B can collect more water droplets, thereby increasing the amount of spray directed to the multiple second tips 142 and increasing the amount of liquid atomized.

[0033] In summary, in the atomizing device of the present invention, the discharge electrode includes a plurality of first tips. The counter electrode includes a plurality of second tips. Since more water droplets can be collected through the plurality of first tips, the amount of sprayed onto the plurality of second tips increases, and the amount of liquid atomized can be increased.

The scope of protection of the present invention shall be determined by the appended claims. [Industrial applicability]
