[0017] FIG. 1 is a schematic three-dimensional view of an atomization device according to an embodiment of the present invention. FIG. 2 is a schematic cross-sectional view of the atomization device of FIG. 1. Referring to FIG. 1 and FIG. 2, the atomization device 100 in this embodiment includes a cooling chip 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 a first side S1 and a second side S2 facing each other. The second side S2 of the discharge electrode 120 is connected to the 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.

[0018] In this embodiment, the counter electrode 140 is disposed at a distance from the discharge electrode 120, and the multiple second tips 142 face the multiple first tips 121. That is, 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 according to actual needs, 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 all fall within the scope of the present invention.

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

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

[0022] In this embodiment, the cooling tip 110 is located between the heat sink 130 and the discharge electrode 120. A current is supplied to the cooling tip 110 via the conductors P3 and P4, and the discharge electrode 120 is cooled via the cooling tip 110. Therefore, condensed water is generated on the surface of the discharge electrode 120, and more moisture present in the air in the base 150 can be collected via the multiple first tips 121. In this embodiment, the cooling tip 110 used to cool the discharge electrode 120 is used as a supply element that supplies water for atomization 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 FIG. 3 and FIG. 4, in this embodiment, the number of the first tips 121 is an even number (eight is shown in outline) and is arranged opposite to each other, but is not limited thereto. The number of the second tips 142 is an even number (eight is shown in outline) and is arranged opposite to each other, but is not limited thereto. Here, the number of the first tips 121 is equal to the number of the second tips 142, but is not limited thereto.

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

[0025] In this embodiment, the hole 141 has a first diameter D1, and the annular body 122 has a second diameter D2, where 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 hole 141.

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

[0027] In this embodiment, the multiple first tips 121 provide a high voltage from a single voltage application unit 21. For example, the discharge electrode 120 holding water at the first tip 121 is configured to have a high voltage applied by the voltage application unit 21, so that the first tip 121 of the discharge electrode 120 can be used as a negative electrode to concentrate electric charge, and the water held at the first tip 121 repeats Rayleigh fission caused by 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 of the counter electrode 140.

[0028] With such an arrangement, the multiple first tips 121 can collect more water droplets, so that the amount of spray to the multiple second tips 142 increases, and the amount of liquid atomized can be increased.

[0029] Fig. 5 is a partial perspective schematic diagram of a nebulizer according to another embodiment of the present invention. Fig. 6 is a cross-sectional schematic diagram of the nebulizer in Fig. 5. Fig. 7 is a top schematic diagram of the nebulizer in Fig. 5. Referring to Figs. 5-7, in this embodiment, the nebulizer 100B is slightly different from the nebulizer 100 in Fig. 4, and the main difference is the type of the discharge electrode 120B.

[0030] In this embodiment, the discharge electrode 120B includes a rod-shaped body 122B. The multiple first tips 121B extend and protrude from one end of the rod-shaped body 122B remote 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 the first tip 121B, is configured to have a high voltage applied by the voltage application unit 21, so that the first tip 121B of the discharge electrode 120B can be used as a negative electrode to concentrate electric charges, and the water held at the first tip 121B repeats Rayleigh fission caused by 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 of the counter electrode 140.

[0032] In this way, the plurality of first tips 121B can collect more water droplets, so that the amount of water sprayed onto the plurality of second tips 142 increases, and the amount of liquid atomized can be increased.

[0033] 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. Since more water droplets can be collected through the plurality of first tips, the amount of spray to the plurality of second tips increases, and the amount of liquid atomized can be increased.

[0034] Although the present invention has been disclosed in the form of embodiments, they are not intended to limit the present invention, and those having ordinary skill in the art to which the invention pertains can make some changes and modifications without departing from the spirit and scope of the present invention. The protection scope of the present invention is to be determined by the appended claims. [Industrial Applicability]
