Description

[Technical Field]

[0001] The present invention relates to the technical field of household electrical appliances, and more particularly to a water ion generating device and electronic device. [Background technology]

[0002] As people's living standards continue to improve and scientific literature fully validates the health benefits of water ions on the human body, manufacturers of electronic devices such as hair dryers, air purifiers, humidifiers, and electrolyzed water filters for air conditioners are increasingly applying water ion technology to their products, thereby providing users with a better product experience.

[0003] However, most of the electronic water ion generators currently on the market use a refrigerant directly as a needle electrode, and the refrigerant is generally made of a material with good thermal conductivity such as aluminum or copper to ensure condensation. Therefore, the refrigerant is susceptible to corrosion and deterioration after prolonged use, which shortens the lifespan of the water ion generator and reduces the amount of water ions produced. Summary of the Invention [Problem to be solved by the invention]

[0004] The purpose of this invention is to propose a water ion generator and an electronic device in consideration of the fact that the majority of water ion generators for various electronic devices currently on the market directly use refrigeration components as needle electrodes, which can lead to corrosion and deterioration of the refrigeration components after long-term use. [Means for solving the problem]

[0005] The water ion generating device comprises a support, an electrode assembly, a cooling assembly, and a high-voltage power supply. The electrode assembly has a needle-shaped electrode and a counter electrode plate. The discharge end of the needle-shaped electrode is placed opposite the counter electrode plate. One side of the needle-shaped electrode is combined with the support to form a liquid passageway. The liquid passageway extends along the longitudinal direction of the needle-shaped electrode to the discharge end of the needle-shaped electrode. The cooling assembly abuts the other side of the needle-shaped electrode, thereby allowing condensed water to accumulate in the liquid passageway. Both ends of the high-voltage power supply are connected to the counter electrode plate and the needle-shaped electrode, respectively. A high-voltage discharge occurs between the discharge end of the needle-shaped electrode and the counter electrode plate, thereby ionizing the condensed water on the discharge end to generate water ions.

[0006] The water ion generating device according to the present invention comprises a support, an electrode assembly, a cooling assembly, and a high-voltage power supply. The electrode assembly includes a needle-shaped electrode and a counter electrode plate formed by combining the needle-shaped electrode into a pair of discharge electrodes. The needle electrode and the counter electrode plate are fixed to the support, one side of the needle electrode is combined with the support to form a liquid passageway, and the other side of the needle electrode is in contact with the cooling assembly. When the cooling assembly is operated, water vapor in the air condenses into condensed water that accumulates in the liquid passageway. When both ends of the high-voltage power supply are connected to the needle electrode and the counter electrode plate, respectively, and a high voltage is applied, the condensed water in the liquid passageway is polarized by the high-voltage electric field formed by the counter electrode plate and the needle electrode and moves directionally toward the discharge end of the needle electrode, thereby generating a high-voltage discharge between the discharge end and the counter electrode plate, ionizing the condensed water on the discharge end and generating water ions. The water ion generating device of the present application uses the discharge end of a needle-shaped electrode to discharge during the water ion generation process, instead of directly discharging the condensation member of the cooling assembly as in the current technology. This prevents the condensation member from accelerating corrosion and aging due to discharge, thereby extending the service life of the condensation member.

[0007] In one embodiment, the support has a cavity, a first opening communicating with the cavity is provided on one side of the support facing the return electrode, the needle electrode and at least a portion of the cooling assembly are installed in the cavity, the needle electrode is arranged horizontally, the discharge end of the needle electrode extends through the first opening to the outside of the cavity and approaches the return electrode, the bottom wall of the needle electrode abuts the cooling assembly, and the top wall of the needle electrode combines with the inner wall of the cavity to form the liquid passage. With this structure, a condensation member is installed in the cavity of the support and abuts the bottom wall of the needle electrode, thereby forming a barrier with the return electrode located outside the cavity, effectively avoiding the problem of accelerated corrosion and aging caused by direct discharge of the condensation member. Furthermore, by arranging the needle electrode horizontally and combining the top wall of the needle electrode with the inner wall of the cavity to form a liquid passage extending horizontally, condensed water can flow uniformly to the discharge end of the needle electrode under the action of the high-voltage electric field generated by the needle electrode and the counter electrode plate.

[0008] In one embodiment, the cooling assembly includes a condensation member and a Peltier cooling element, the condensation member being installed in the cavity together with the Peltier cooling element, the Peltier cooling element being used to cool the condensation member, and the side of the condensation member away from the Peltier cooling element abutting the bottom wall of the needle electrode. Through this structure, the device uses the discharge end of the needle electrode for discharge instead of the condensation member during the water ion generation process. Specifically, the needle electrode is made of a material that is resistant to corrosion caused by discharge, such as stainless steel or titanium alloy, thereby solving the problems of corrosion and aging of the condensation member and extending the service life of the cooling assembly.

[0009] In one embodiment, the liquid passage includes a water tank and a first passage, a top wall of the cavity protrudes inward to form an annular mounting portion, a mounting hole is formed inside the annular mounting portion, a first notch is provided on one side of a side wall of the mounting hole that is close to the first opening, the condensation member is fitted to the bottom of the mounting hole, and the bottom wall of the condensation member abuts against the Peltier cooling element, the needle electrode has a body, a first flow guide portion, and a discharge end, The main body is installed in the mounting hole and abuts against the top of the condensation member, the water tank is surrounded by the main body and the inner wall of the top of the mounting hole and / or the condensation member, one end of the first flow guide portion connects to the periphery of the main body, the other end of the first flow guide portion extends through the first notch to the first opening and connects to the discharge end, the first path is surrounded by the top wall of the first flow guide portion and the inner wall of the cavity, and the water tank is in communication with the first opening via the first path. The top wall of the cavity protrudes inward to form an annular mounting portion, which allows the condensation member to be aligned with and attached to the needle electrode. When the needle electrode body and the condensation member are placed in the mounting hole from top to bottom, one side of the needle electrode body abuts against the condensation member for cooling. The other side, the inner wall of the top of the mounting hole, and / or the condensation member surround the water reservoir, allowing the opening of the water reservoir to directly communicate with the outside environment, allowing external air to better contact the body and / or the condensation member to generate condensation water. Furthermore, the periphery of the body is connected to the discharge end via the first flow-directing portion, and the top wall of the first flow-directing portion and the inner wall of the cavity surround the first path, allowing the condensation water formed in the water reservoir to move accurately and quickly along the first path to the discharge end under the action of the high-voltage electric field generated by the needle electrode and the counter electrode.

[0010] In one embodiment, the needle electrode further includes a second flow guide portion, the side wall of the mounting hole having a second notch opposite the first notch, the support having a second opening opposite the first opening, one end of the second flow guide portion connecting to the periphery of the main body, the other end of the second flow guide portion extending through the second notch to the second opening, and a second passage surrounded by the top wall of the second flow guide portion and the inner wall of the cavity, the second passage communicating with the water tank. This structure, on the one hand, allows the needle electrode to be more easily inserted onto the support, thereby improving installation efficiency, and on the other hand, allows the water tank to communicate with the external environment via the second passage, which may be advantageous in improving condensation water generation efficiency. Preferably, the second flow guide portion is made of a metal material, which allows the second flow guide portion to connect to the main body and synchronously cool it, and to combine with the main body to allow water vapor in the air to condense into condensation water.

The through-groove on the top wall of the condensation member is fitted to the main body of the needle electrode, which serves as a positioning mechanism and facilitates quick connection between the main body and the condensation member. On the other hand, the top wall of the main body is located at a lower or the same height as the top wall of the condensation member, which allows condensed water stored in the water reservoir to easily drop and transfer to the upper surface of the main body, thereby improving the efficiency of water ion generation.

[0012] In one embodiment, the cooling assembly further includes a heat dissipation member, the support member is installed above the heat dissipation member, and the mounting cavity is surrounded by the inner wall of the cavity and the heat dissipation member. The needle electrode, the condensation member, and the Peltier cooling element are sequentially arranged in the mounting cavity from top to bottom. The Peltier cooling element has a heat dissipation end and a cooling end facing each other, with the cooling end of the Peltier cooling element abutting the condensation member and the heat dissipation end of the Peltier cooling element abutting the heat dissipation member. The heat dissipation member allows for rapid dissipation of heat generated at the heat dissipation end of the Peltier cooling element, thereby maintaining and improving the cooling effect of the cooling end. Furthermore, the mounting cavity is surrounded by the heat dissipation member and the support member, effectively blocking external moisture and ensuring stable operation of the Peltier cooling element.

With the above structure, the mounting seat and the positioning post are used to align the needle electrode with the return electrode plate, respectively, so that the needle electrode and the return electrode plate automatically correspond to each other when they are mounted on the support according to predetermined positions.

[0015] In one embodiment, the diameter of the first opening gradually decreases in the direction toward the return electrode, and the discharge tip is fitted into the first opening. Through the above structure, the first opening can achieve positional restriction on the discharge tip of the needle electrode, thereby enabling the needle electrode to be fitted accurately and quickly at a predetermined position and maintaining an effective distance between the discharge tip and the return electrode.
