[0037] like Figures 1 to 8 The diagram shows a portable negative ion generator according to a preferred embodiment of the present invention. It includes a negative ion mist generating mechanism 10, a water supply mechanism 20, a blower mechanism 30, and a cup body 40. The negative ion mist generating mechanism 10, water supply mechanism 20, and blower mechanism 30 are mounted on the cup body 40. The water supply mechanism 20 supplies water to the negative ion mist generating mechanism 10, causing the water to be rubbed at high frequency to generate negative ions when the mechanism is working. The blower mechanism 30 draws air into the portable negative ion generator and blows the negative ions generated by the mechanism to the outside to carry them into the environment. In this invention, the cup body 40 is constructed to resemble a water cup, and its size is similar to that of an ordinary water cup, making it easy to carry. Users can then take it to their workplace, home, or while traveling, and generate negative ions in indoor spaces.

[0038] like Figure 2 and Figure 3As shown, the negative ion water mist generating mechanism 10 includes a water friction unit 11, a controller 12, a cavity 13, a buffer sleeve 14, and a power module 15. The cavity 13 has a water guiding channel 131 and a water storage channel 132 that are connected to each other, so that water in the water supply mechanism 20 can enter and reach the water guiding channel 131 and the water storage channel 132. The water friction unit 11 is housed in the buffer sleeve 14 and installed in the cavity 13, so that the water friction unit 11 can vibrate at a high frequency when it is electrically connected to the controller 12 and driven by the power supply module 15, so that the water entering the water storage channel 132 rubs against the water friction unit 11 to generate tiny droplets with charges, thereby generating negative ion water mist.

[0039] In this embodiment, the negative ion water mist generating mechanism 10 is schematically shown to include two water friction units 11, and the cavity 13 is arranged in a vertical direction to form a vertical water guiding channel 131 and two horizontally extending water storage channels 132. The two water friction units 11 are respectively installed in the two water storage channels 132 to generate negative ion water mist by rubbing the water stored in the corresponding water storage channels 132.

[0040] More specifically, such as Figures 4 to 7 As shown, in this embodiment, each water friction unit 11 includes a friction plate 111 and a piezoelectric plate 112 attached to and electrically connected to the friction plate 111. The piezoelectric plate 112 and the friction plate 111 are electrically connected to the controller 12 and are powered by the power module 15. The piezoelectric plate 112 and the friction plate 111 can be electrically connected to the controller 12 respectively by wires 114.

[0041] It is understood that in this invention, each water friction unit 11 includes a friction plate 111 and at least one piezoelectric plate 112, so that it can be driven to generate vibration under the control of the controller 12, so that the friction plate 111 rubs against the water in the water storage channel 132 at high frequency to generate negative ion water mist.

[0042] like Figures 4 to 7 As shown, preferably in this embodiment, each water friction unit 11 includes two piezoelectric sheets 112 and one friction sheet 111, and can be electrically connected to the controller 12 by three wires 114 respectively. The friction sheet 111 is located between the two piezoelectric sheets 1112.

[0043] The three wires 114 include two positive electrode wires 1141 and one negative electrode wire 1142. The two positive electrode wires 1141 are electrically connected to the two piezoelectric sheets 112, and the negative electrode wire 1142 is electrically connected to the friction plate 111. Thus, each piezoelectric sheet 112 and friction plate 111 can form a friction unit, causing the friction plate 111 to vibrate at high frequency in response to a voltage signal input. It can be understood that the two piezoelectric sheets 112 and one friction plate 111 form two friction components. The controller 12 can drive one friction component to be in operation while the other friction component is not in operation due to the lack of an input voltage signal. By alternately applying excitation signals, the overall lifespan of the water friction unit 11 is doubled compared to a single-layer piezoelectric sheet water friction unit.

[0044] It is worth mentioning that each piezoelectric sheet 112 can also be electrically connected to the controller through two positive and negative wires, so that each friction component is energized on the same side, and the friction plate 111 is insulated from each piezoelectric sheet 112. When an excitation signal is input to each piezoelectric sheet 112, its vibration will drive the friction plate 111 to vibrate at a high frequency.

[0045] It is worth mentioning that, in order to ensure that the water in contact with the friction plate 111 can resonate to generate tiny droplets and to enable the tiny droplets to have sufficient high-frequency friction with the friction plate 111, the voltage applied to the piezoelectric plate 112 needs to be able to drive the friction plate 111 to vibrate at a high frequency. Preferably, when the voltage applied to the piezoelectric plate 112 is 110±KHz with a peak value of 60V-90V, the friction plate 111 can vibrate at a high frequency and generate a high concentration of negative water ions, and the negative water ions can migrate a long distance.

[0046] The friction plate 111 has a central region 1111 and an outer ring region, wherein the piezoelectric plate 112 is a piezoelectric ceramic and is ring-shaped, which is attached to the outer ring region of the friction plate 111, and the central region 1111 of the friction plate 111 has a plurality of micropores 1113 to form a mesh-like structure.

[0047] Preferably, the friction plate 111 has a diameter of 10-20 mm, with a central region 111 having a diameter of 1-10 mm. It contains 500-5000 micropores 1113, and the micropores 1113 are extremely small. In this invention, the size of the micropores 1113 is less than 10 μm, and preferably, the opening size is less than 5 μm. This is because the amount of negative water ions generated by the microdroplets is positively correlated with the negative charge density. The negative charge density depends on the contact time with the friction plate 111, the contact area, and the charge density of the friction plate 111. Therefore, the smaller the size of the microdroplets, the higher their average charge density, and thus the higher the amount of negative water ions generated. In other words, droplets with smaller diameters are more likely to generate negative water ions, and the concentration of negative water ions is higher.

[0048] Friction plate 111 is used to vibrate and impact the liquid in water storage channel 132, thereby generating negative ions. A corresponding buffer sleeve 14 is fitted to friction plate 111 so that when friction plate 111 vibrates to generate negative water ions, it simultaneously impacts buffer sleeve 14, thus preventing noise from the friction plate 111 impacting the water. More specifically, when a voltage of a predetermined frequency and peak value is applied to piezoelectric plate 112 and friction plate 111, friction plate 111 generates high-frequency vibration and strikes buffer sleeve 14, causing the water between buffer sleeve 14 and friction plate 111 to resonate and generate tiny droplets. Simultaneously, these tiny droplets rub against friction plate 111 at high frequency between friction plate 111 and buffer sleeve 14, further acquiring a negative charge to form negative water ions, which diffuse from the micropores 1113 into the environment. Blowering mechanism 30 blows air, carrying the negative water ions released from the micropores 1113 to diffuse into the external environment, increasing the migration distance of the negative water ions.

[0049] The buffer sleeve 14 is made of an elastic material, such as elastic silicone or elastic rubber, and includes an annular fixing piece 141, a buffer piece 142, and a connecting piece 143. The buffer piece 142 extends inwardly from the annular fixing piece 141 through the connecting piece 143. The water friction unit 11 is embedded in the buffer sleeve 14. The position of the buffer piece 142 corresponds to the central region 1111 of the friction piece 111, which has multiple micropores 1113. When the friction piece 111 vibrates at high frequency, the central region 1111 with multiple micropores 1113 impacts the buffer piece 142, thereby buffering the vibration of the friction piece 111 and reducing the noise when hitting the liquid.

[0050] The buffer plate 142 and the negative ion water mist generating mechanism 11 are located in the inner cavity 144 of the annular fixing plate 141. In this embodiment, the negative ion water mist generating mechanism 11 has a groove 1121 formed by the annular piezoelectric plate 112 facing the buffer plate 142, and a protrusion 141 formed on the buffer plate 142, which extends into the groove 1121, so that the protrusion 142 contacts the friction plate 111.

[0051] The central region 1111 of the friction pad 111, which has multiple micropores 1113, comes into contact with the protrusions 142 of the buffer pad 142. When the protrusions 142 of the buffer pad 142 are struck by the central region 1111 of the friction pad 111, they are confined within the inner cavity 144 to elastically vibrate, thereby providing elastic cushioning for the central region 1111 of the friction pad 111, and simultaneously allowing the central region 1111 of the friction pad 111 to rub against the liquid, thereby charging the tiny droplets and generating negative ion water mist.

[0052] like Figure 2 and Figure 3 As shown in the figure, the portable water negative ion generating device of the present invention may also include a charging device 50, which is a high-voltage discharge module whose driving voltage can be raised to preferably above -4kV, so as to charge the water mist generated by the water friction unit 11. That is, the electrons generated by the charging needle are absorbed by the water mist generated by the water friction unit 11 in a timely manner, thereby generating negative ion water mist rich in negative ions.

[0053] The friction plate 111 of the portable negative ion generator charges the atomized droplets through triboelectric charging. This makes it easier for the negative charge generated by the charging device 50 to be adsorbed onto the negative ion water mist, resulting in a higher concentration of negative charge adsorbed by the water ions and easier saturation. In other words, the portable negative ion generator of the present invention not only atomizes the droplets but also makes the atomized water mist itself carry negative ions, thus forming a negative ion water mist. In this way, the negative ion water molecules are more likely to adsorb the negative charge supplemented by the charging device. Therefore, compared to simply atomizing uncharged droplets being charged, the already charged negative ion water mist of the present invention is more easily charged to produce a higher concentration of negative ions.

[0054] In this invention, the charging device 50 is disposed between the two water friction units 11, so that the negative ion water mist generated by the two water friction units 11 can be charged to generate a high concentration of water negative ions. Therefore, compared with the negative ion generating devices of the prior art, the portable water negative ion generating device of this invention can generate a higher concentration of water negative ions.

[0055] The cup body 40 of the portable negative ion generator of the present invention has an elongated shape, such as a three-dimensional body, and preferably, in this embodiment, a cylindrical shape. The cup body 40 includes a main body 41 and a base 42. The main body 41 is cylindrical and is disposed on the base 42, with an air inlet channel 43 formed between the two. The cup body 40 has an outlet 44 on its peripheral side. The negative ion water mist generating mechanism 10 and the blower mechanism 30 are disposed inside the main body 41 of the cup body 40, and the water supply mechanism 20 is disposed on the top of the main body 41 of the cup body 40.

[0056] like Figure 2 and Figure 3 As shown, in this embodiment of the invention, the air inlet channel 43 is disposed on the bottom side of the cup body 40 and located below the blower mechanism 30. Thus, the blower mechanism 30 draws air into the interior of the portable water negative ion generator from the air inlet channel 43 on the bottom side of the main body 41 of the cup body 40 and blows it out from the outlet 44 on the side of the cup body 40, thereby blowing the water negative ions generated by the negative ion water mist generating mechanism 10 and the charging device 50 out of the portable water negative ion generator from the outlet 44.

[0057] In this invention, the position of the air inlet channel 43 at the bottom side of the cup body 40 means that the air inlet channel 43 is located below the middle of the cup body 40, so that the air enters the cup body 40 from the lower end and then moves upward to reach the negative ion water mist generating mechanism 10.

[0058] The blower mechanism 30 includes a fan 31 and a filter 32, wherein the fan 31 is located above the filter 32, so that the air entering the cup body 40 passes through the filter 32 and is then sent to the negative ion water mist generating mechanism 10 via the fan 31.

[0059] Understandably, in order to facilitate the compact design of the portable water negative ion generator, the air inlet channel 43 is located on the lower side of the cup body 40, and the air reaches the blower structure 30 from bottom to top, and after passing through the blower structure 30, it continues to diffuse upward toward the negative ion water mist generating mechanism 10, and finally turns laterally and leaves the portable water negative ion generator horizontally through the outlet 44 on the side of the cup body 40.

[0060] Accordingly, in the portable water negative ion generator of the present invention, the water supply mechanism 20 is arranged on the top side of the cup body 40, and then the negative ion water mist generating mechanism 10 and the charging device 50 are arranged sequentially from top to bottom, followed by the blower mechanism 30, so that the portable water negative ion generator can be arranged in a miniaturized structure to reduce its size and make it easy to carry.

[0061] refer to Figure 8 As shown, the water supply mechanism 20 includes a water storage cavity 21 and a connector 22, wherein the connector is suitable for connecting to a common water bottle 60, such as a 500-600ml mineral water bottle, so that the water bottle 60 can be inverted above the water supply mechanism 20 after removing its cap, so that the water in the mineral water bottle 60 is supplied to the cavity 13 of the negative ion water mist generating mechanism 10, thereby supplying water to the water storage channel 132 for friction by the water supply friction unit 11 to generate water negative ion water mist.

[0062] The connector 22 can be housed within the water bottle 60, and a water-guiding passage is formed within the connector 22, allowing water from the water bottle 60 to enter the cavity 13 of the negative ion water mist generating mechanism 10 from the water storage chamber 21, and then reach the water storage channel 132 via the water guiding channel 131. It is understood that, in another embodiment, the connector 22 can also be a threaded connector, with the threaded portion at the head of the water bottle 60 threadedly connected to the connector 22, thereby allowing the water bottle 60 to be inverted and stably fixed to the water supply mechanism 20 of the main body 41 of the cup body 40 to provide a water supply. By inverting the water bottle 60 in this way, the space of the water storage chamber of the portable negative ion generating device can be further reduced, thereby further reducing the size of the portable negative ion generating device.

[0063] Of course, those skilled in the art will understand that in other variations, the water supply mechanism 20 may not have the aforementioned connector 22, and the water bottle 60 may not be inverted on the water supply mechanism 20, but water can be directly added to the water storage chamber 21 of the water supply mechanism 20.

[0064] It is understood that the portable negative ion generator of the present invention can naturally generate negative ions by simulating the impact of a waterfall on the ground, that is, by generating negative ions through high-frequency friction of water. The concentration of negative ions in the water around the waterfall is 10,000-50,000 per cubic centimeter. 3 The negative ion excitation device of the present invention can generate negative ions that can migrate up to 200 cm, and the concentration of negative ions within a 200 cm range can reach 30,000 ions / cm³. 3 above.
