Description

Portable water negative ion generator and vehicle-mounted water negative ion aromatherapy device Technical Field

[0001] The present invention relates to the technical field of negative ions, in particular to a portable water negative ion generating device and a vehicle-mounted water negative ion aromatherapy device. Background Art

[0002] Negative ions have many functions. For example, negative ions can capture pollutants in the air, such as dust, smoke, etc., thereby improving air quality; they can destroy the cell membranes of bacteria, thereby killing bacteria; they can promote blood circulation in the human body, enhance immunity, and improve sleep.

[0003] The structure of negative ion generators can be designed based on their different operating principles and usage scenarios. Industrial negative ion generators typically use nanomaterial-based negative ion generators. Home or workplace negative ion generators typically use corona discharge or electrostatic adsorption-based negative ion generators. Technical issues

[0004] However, traditional negative ion generators on the market are all desktop machines, which are generally equipped with a negative ion generating module, such as a high-voltage module, for discharging and generating negative ions. These devices are not easy to carry and the amount of negative ions they produce is limited.

[0005] With the development of society and advancements in technology, people's demands for a higher quality of life are becoming increasingly stringent. This is especially true when it comes to transportation, where people are beginning to pay attention to the comfort and health of their vehicle's interior environment. In-car aromatherapy devices are devices used to distribute fragrance within the vehicle. They help eliminate odors and create a fresh and pleasant atmosphere.

[0006] There are many types of car aromatherapy devices. For example, a drip-type aromatherapy device typically consists of a glass or ceramic container filled with fragrance oil. The oil drips slowly through a dropper onto a diffuser, diffusing the aroma molecules into the car. Wind-powered aromatherapy devices utilize the car's air conditioning fan to diffuse the aroma. These devices are typically clipped to the car's air vents or placed on the dashboard. Electronic aromatherapy devices use batteries or the car's power supply to heat the fragrance oil or wax and diffuse it into the air.

[0007] However, existing car-mounted aroma devices generally cannot release fragrance evenly and continuously into the car. More importantly, the fragrance released by such aroma devices may only mask the unpleasant odor in the car and does not truly solve the root cause of the problem. In other words, it does not fundamentally purify the air in the car. Technical Solutions

[0044] As shown in Figures 1 to 8, a portable water negative ion generating device according to a preferred embodiment of the present invention includes a negative ion water mist generating mechanism 10, a water supply mechanism 20, an air blowing mechanism 30 and a cup body 40, wherein the negative ion water mist generating mechanism 10, the water supply mechanism 20 and the air blowing mechanism 30 are installed in the cup body 40, the water supply mechanism 20 is used to supply water to the negative ion water mist generating mechanism 10, so that when the negative ion water mist generating mechanism 10 is working, water is rubbed by high frequency to produce water negative ions, and the air blowing mechanism 30 draws air into the portable water negative ion generating device and blows the water negative ions produced by the negative ion water mist generating mechanism 10 to the outside to carry the water negative ions to the environment. In the present invention, the cup body 40 is constructed to look like a water cup, and its volume is also similar to that of an ordinary water cup, so that it is easy to carry. Thus, the user can carry it to work, home, or travel places and produce water negative ions in indoor places.

[0045] As shown in Figures 2 and 3, 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, wherein the cavity 13 has a connected water guide channel 131 and a water storage channel 132, so that the water in the water supply mechanism 20 can enter the water guide channel 131 and reach the water storage channel 132, and the water friction unit 11 is accommodated in the buffer sleeve 14 and installed in the cavity 13, so that the water friction unit 11 can be electrically connected to the controller 12 and driven under the power supply of the power module 15. It can vibrate reciprocatingly at a high frequency so that the water entering the water storage channel 132 rubs against the water friction unit 11 to generate tiny droplets with electric charge to generate negative ion water mist.

[0046] In this embodiment, the negative ion water mist generating mechanism 10 is illustrated as including two water friction units 11, and the cavity 13 is arranged in the vertical direction, forming a vertical water guide channel 131 and two water storage channels 132 extending horizontally. The two water friction units 11 are respectively installed in the two water storage channels 132, so as to rub the water stored in the corresponding water storage channels 132 to generate negative ion water mist.

[0047] More specifically, as shown in Figures 4 to 7, in this embodiment, each water friction unit 11 includes a friction plate 111 and a piezoelectric plate 112 adhered to and electrically connected to the friction plate 111, wherein the piezoelectric plate 112 and the friction plate 111 are electrically connected to the controller 12 and are supplied with electrical energy by the power module 15, and the piezoelectric plate 112 and the friction plate 111 can be electrically connected to the controller 12 respectively through a wire 114.

[0048] It can be understood that in the present 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 and the water in the water storage channel 132 can generate negative ion water mist through high-frequency friction.

[0049] As shown in Figures 4 to 7, 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 through three wires 114 respectively, and the friction sheet 111 is located between the two layers of piezoelectric sheets 1112.

[0050] 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 layers of piezoelectric sheets 112, respectively, while the negative electrode wire 1142 is electrically connected to the friction sheet 111. Thus, each piezoelectric sheet 112 and friction sheet 111 form a friction unit, which, in response to the input of a voltage signal, causes the friction sheet 111 to generate high-frequency vibrations. It is understood that the two piezoelectric sheets 112 and one friction sheet 111 form two friction assemblies. The controller 12 can drive one of the friction assemblies into operation while the remaining friction assembly is not operated due to the input voltage signal. By alternating the input of the excitation signal, the overall lifespan of the water friction unit 11 is doubled that of a water friction unit with a single layer of piezoelectric sheets.

[0051] It is worth mentioning that each layer of piezoelectric sheet 112 can also be electrically connected to the controller through two positive and negative wires, so that each friction component is powered on the same side, and the friction sheet 111 is insulated from each layer of piezoelectric sheet 112. When an excitation signal is input into each layer of piezoelectric sheet 112, its vibration will drive the friction sheet 111 to vibrate at a high frequency.

[0052] It's worth noting that to ensure that water in contact with friction plate 111 resonates to generate tiny droplets and that the tiny droplets rub against friction plate 111 at sufficient high frequency, the voltage applied to piezoelectric plate 112 must be able to drive friction plate 111 to vibrate at high frequency. Preferably, when the voltage applied to piezoelectric plate 112 is at a frequency of 110±kHz and a peak value of 60V-90V, friction plate 111 vibrates at high frequency, generating a high concentration of negative water ions, and the migration distance of the negative water ions is relatively long.

[0053] The friction plate 111 has a central area 1111 and an outer ring area, wherein the piezoelectric plate 112 is a piezoelectric ceramic and is annular, which is attached to the outer ring area of ​​the friction plate 111. The central area 1111 of the friction plate 111 has multiple micropores 1113 to form a mesh structure.

[0054] Preferably, the friction plate 111 has a diameter of 10-20 mm, with a central region 111 having a diameter of 1-10 mm. The number of micropores 1113 is 500-5000, and the micropores 1113 are extremely small. In the present invention, the micropores 1113 are less than 10 μm, and preferably, their opening size is less than 5 μm. This is because the amount of negative water ions generated by a tiny droplet is positively correlated with its negative charge density, which depends on the contact time and area with the friction plate 111, as well as the charge density of the friction plate 111. Therefore, the smaller the droplet size, the higher its average charge density, and thus the greater 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 these ions is higher.

[0055] The friction plate 111 is designed to vibrate and impact the liquid in the friction water storage channel 132, generating negative ions. The corresponding buffer sleeve 14 is positioned in contact with the friction plate 111, ensuring that when the friction plate 111 vibrates and generates negative water ions, it simultaneously impacts the buffer sleeve 14, thus preventing the friction plate 111 from generating noise due to the impact of the water. More specifically, when a voltage of a predetermined frequency and peak value is applied to the piezoelectric plate 112 and the friction plate 111, the friction plate 111 generates high-frequency vibrations that strike the buffer sleeve 14, causing the water between the buffer sleeve 14 and the friction plate 111 to resonate and generate tiny droplets. These droplets then rub against the friction plate 111 at high frequency, further acquiring a negative charge and forming negative water ions. These ions then diffuse from the micropores 1113 into the surrounding environment. The air blowing mechanism 30 blows air, carrying the negative water ions released from the micropores 1113 toward the external environment, thereby increasing their migration distance.

[0056] The buffer sleeve 14 is made of an elastic material, such as elastic silicone or elastic rubber, and includes an annular fixing plate 141, a buffer plate 142 and a connecting plate 143. The buffer plate 142 extends inwardly and integrally to the annular fixing plate 141 through the connecting plate 143. The water friction unit 11 is buried in the buffer sleeve 14. The position of the buffer plate 142 corresponds to the central area 1111 of the friction plate 111 having multiple micropores 1113. In this way, when the friction plate 111 vibrates at a high frequency, the central area 1111 having multiple micropores 1113 correspondingly impacts the buffer plate 142, thereby buffering the vibration of the friction plate 111 and reducing the noise when hitting the liquid.

[0057] 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 is formed with a groove 1121 on the piezoelectric plate 112 facing the buffer plate 142. The buffer plate 142 is formed with a protrusion 141, which extends into the groove 1121, so that the protrusion 142 contacts the friction plate 111.

[0058] The central region 1111 of the friction plate 111, which has a plurality of micropores 1113, thus contacts the protrusions 142 of the buffer plate 142. When struck by the central region 1111 of the friction plate 111, the protrusions 142 of the buffer plate 142 are confined within the inner cavity 144 and elastically vibrate, thereby elastically cushioning the central region 1111 of the friction plate 111 and simultaneously allowing the central region 1111 of the friction plate 111 to rub against the liquid, thereby charging the tiny liquid droplets and generating negative ion water mist.

[0059] As shown in Figures 2 and 3, in addition, 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, and its driving voltage can be increased to preferably above -4kV to charge the water mist generated by the water friction unit 11, that is, the electrons generated by the charging needle are promptly absorbed by the water mist generated by the water friction unit 11, thereby generating negative ion water mist rich in negative ions.

[0060] The friction plate 111 of the portable water negative ion generating device charges the atomized droplets through triboelectric charging. This allows the negative charges generated by the charging device 50 to be more easily adsorbed by the negative ion water mist, thereby increasing the concentration of negative charges adsorbed by the water ions and making it easier for the negative charge to be saturated. In other words, the portable water negative ion generating device of the present invention not only atomizes the droplets, but also causes the atomized water mist itself to carry negative ions, thereby forming a negative ion water mist. In this way, the negative ion water molecules are more likely to adsorb the negative charges added by the charging device. As a result, compared to the charging of the atomized, uncharged droplets, the already charged negative ion water mist of the present invention is more easily supplemented with charges, thereby generating water negative ions with a higher negative ion concentration.

[0061] In the present invention, the charging device 50 is arranged between the two water friction units 11, so that the negative ion water mist generated by the two water friction units 11 can be supplemented with electric charge to produce high-concentration water negative ions. Therefore, compared with the negative ion generating equipment in the prior art, the portable water negative ion generating device of the present invention can produce water negative ions with a higher concentration.

[0062] The cup body 40 of the portable water negative ion generating device of the present invention has an elongated shape, such as a three-dimensional object. Preferably, in this embodiment, it has a cylindrical shape. The cup body 40 includes a main body 41 and a base 42. The main body 41 is cylindrical and is mounted on the base 42, with an air inlet passage 43 formed therebetween. The cup body 40 has an outlet 44 on its side. The negative ion water mist generating mechanism 10 and the air blowing mechanism 30 are disposed within the main body 41 of the cup body 40. The water supply mechanism 20 is disposed on the top of the main body 41 of the cup body 40.

[0063] As shown in Figures 2 and 3, in this embodiment of the present invention, the air inlet channel 43 is arranged on the bottom side of the cup body 40 and is located below the blowing mechanism 30, so that the blowing mechanism 30 draws air into the interior of the portable water negative ion generating device from the air inlet channel 43 of the bottom part 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 generating device from the outlet 44.

[0064] In the present invention, the position of the air inlet channel 43 on the bottom side of the cup body 40 means that the air inlet channel 43 is set below the middle of the cup body 40, so that the wind enters the cup body 40 from the lower end of the cup body 40, and then moves upward to reach the negative ion water mist generating mechanism 10.

[0065] The air blowing 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 then is sent to the negative ion water mist generating mechanism 10 through the fan 31 .

[0066] It can be understood that in order to facilitate the compact structural design of the portable water negative ion generating device, the air inlet channel 43 is set at the lower side of the cup body 40, and the wind reaches the blowing structure 30 from bottom to top, and continues to diffuse upward toward the negative ion water mist generating mechanism 10 after passing through the blowing structure 30, and finally turns horizontally and leaves the portable water negative ion generating device horizontally through the outlet 44 on the side of the cup body 40.

[0067] Correspondingly, in the portable water negative ion generating device 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 in sequence from top to bottom, and then the blowing mechanism 30, so that the portable water negative ion generating device can be arranged in a miniaturized structure to reduce its volume, thereby facilitating portability.

[0068] As shown in reference Figure 8, the water supply mechanism 20 includes a water storage cavity 21 and a connector 22, wherein the connector is suitable for connecting to an ordinary 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 bottle 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 with the water supply friction unit 11 to generate water negative ion water mist.

[0069] The connector 22 can be accommodated within the water bottle 60, and a water conduit is formed in the connector 22, allowing water in 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 conduit 131. It is understood that in other embodiments, the connector 22 can also be a threaded connector, and the threaded portion at the head end of the water bottle 60 can be 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 manner, the portable water negative ion generating device can further reduce the space in its water storage chamber, thereby further reducing the volume of the portable water negative ion generating device.

[0070] Of course, those skilled in the art will understand that, in other modified embodiments, the water supply mechanism 20 may not have the above-mentioned connector 22, and the water bottle 60 may not be inverted on the water supply mechanism 20, but water may be added directly to the water storage chamber 21 of the water supply mechanism 20.

[0071] It is understood that the portable water negative ion generating device of the present invention can naturally generate water negative ions by simulating the way a waterfall hits the ground, that is, by generating water negative ions through high-frequency friction of water. The concentration of water negative ions around the waterfall is 10,000 to 50,000 / cm³. The negative ions of the water negative ion excitation device of the present invention can migrate to 200cm, and the concentration of negative ions within 200cm can reach 30,000 / cm³. 3 above.

[0072] As shown in Figures 9 to 15, a vehicle-mounted water negative ion aromatherapy device according to a preferred embodiment of the present invention includes an aromatherapy negative ion water mist generating unit 710, a fragrance liquid supply cavity 720, a fan unit 730 and a housing 740, wherein the aromatherapy negative ion water mist generating unit 710, the fragrance liquid supply cavity 720 and the fan unit 730 are installed in the housing 740, and the fragrance liquid supply cavity 720 is used to provide water mixed with fragrance to the aromatherapy negative ion water mist generating unit 710, so that when the fragrance therapy negative ion water mist generating unit 710 is working, the water is subjected to high-frequency friction to generate water negative ions mixed with fragrance molecules, namely, fragrance therapy negative ion water mist. The fan unit 730 draws air into the vehicle-mounted water negative ion aromatherapy device and blows the fragrance therapy negative ion water mist generated by the fragrance therapy negative ion water mist generating unit 710 to the outside to carry the fragrance therapy negative ion water mist to the vehicle interior environment.

[0073] As shown in Figures 10 and 11, the aromatherapy negative ion water mist generating unit 710 includes a friction mechanism 711, a controller 712, a liquid guiding cavity 713, an elastic buffer element 714 and a power module 715, wherein the liquid guiding cavity 713 has a connected liquid guiding channel 7131 and a liquid storage channel 7132, so that the fragrance solution in the fragrance supply cavity 720 can enter the liquid guiding channel 7131 and reach the liquid storage channel 7132, and the friction mechanism 711 is arranged corresponding to the elastic buffer element 714 and is installed in the liquid guiding cavity 713, so that the friction mechanism 711 can be electrically connected to the controller 712 and driven by the power module 715. It can vibrate back and forth at a high frequency, so that the fragrance solution entering the liquid storage channel 7132 rubs against the friction mechanism 711, thereby generating tiny droplets with electric charge and mixed with fragrance molecules to generate aromatherapy negative ion water mist.

[0074] The aforementioned perfume solution is formed by adding liquid fragrance ingredients to water and mixing them. The fragrance ingredients can be various natural or artificial fragrances, such as lavender oil, lemon essential oil, sandalwood oil, rose essential oil, butyl acetate, phenylethyl alcohol, geraniol, ethyl citrate, vanillin, etc. The perfume solution can be mixed evenly before being added to the fragrance liquid supply chamber 720. Alternatively, the fragrance liquid supply chamber 720 can be further provided with a stirring mechanism to evenly mix the fragrance ingredients with the water when the device is opened.

[0075] In a typical application, the flavoring ingredient is a plant hydrosol, which is a by-product obtained by distillation or steam distillation during the extraction of plant essential oils. It is a plant essence solution with the fragrance and efficacy of plants. In the present invention, adding water as a perfume solution will not affect the generation of negative ions. Common hydrosols can be rose hydrosol, bitter orange flower hydrosol, jasmine hydrosol, osmanthus hydrosol, lotus hydrosol, gardenia hydrosol, magnolia hydrosol, lemon flower hydrosol, blue tansy hydrosol, chamomile hydrosol, grapefruit leaf hydrosol, geranium hydrosol, rosemary hydrosol, lavender hydrosol, tea tree hydrosol, mint hydrosol, lemon balm hydrosol, cinnamon hydrosol, Centella asiatica hydrosol, saffron hydrosol, sandalwood hydrosol, agarwood hydrosol, frankincense hydrosol, thuja hydrosol, mahogany hydrosol, wormwood hydrosol, etc.

[0076] In this embodiment, the aromatherapy negative ion water mist generating unit 710 is illustrated as including two friction mechanisms 711, and the liquid guide cavity 713 is arranged in the vertical direction, which forms a vertical liquid guide channel 7131 and two liquid storage channels 7132 extending in the horizontal direction. The two friction mechanisms 711 are respectively installed in the two liquid storage channels 7132, so as to rub the water stored in the corresponding liquid storage channels 7132 to generate aromatherapy negative ion water mist.

[0077] More specifically, as shown in Figures 13 to 15, in this embodiment, each friction mechanism 711 includes a friction layer 7111 and a piezoelectric ceramic layer 7112 adhered to and electrically connected to the friction layer 7111, wherein the piezoelectric ceramic layer 7112 and the friction layer 7111 are electrically connected to the controller 712 and are supplied with electrical energy by a power supply module 715, and the piezoelectric ceramic layer 7112 and the friction layer 7111 can be electrically connected to the controller 712 respectively through a wire 7114.

[0078] It can be understood that in the present invention, each friction mechanism 711 includes a friction layer 7111 and a piezoelectric ceramic layer 7112, so that it can be driven to generate vibration under the control of the controller 712, so that the friction layer 7111 and the fragrance water solution in the liquid storage channel 7132 can generate fragrance negative ion water mist through high-frequency friction.

[0079] It is worth mentioning that the piezoelectric ceramic layer 7112 can also be electrically connected to the controller through two positive and negative wires, so that each friction component is powered on the same side, and the friction layer 7111 is insulated from each piezoelectric ceramic layer 7112. When an excitation signal is input into each piezoelectric ceramic layer 7112, its vibration will drive the friction layer 7111 to vibrate at a high frequency.

[0080] It's worth noting that to ensure that water in contact with friction layer 7111 resonates to generate tiny droplets and that the tiny droplets rub sufficiently at high frequencies against friction layer 7111, the voltage applied to piezoelectric ceramic layer 7112 must be able to drive friction layer 7111 to vibrate at high frequencies. Preferably, when the voltage applied to piezoelectric ceramic layer 7112 is 110±kHz with a peak value of 60V-90V, friction layer 7111 vibrates at high frequencies, generating a high concentration of negative water ions, and the negative water ions migrate over a long distance.

[0081] The friction layer 7111 has a central area 71111 and an outer ring area, wherein the piezoelectric ceramic layer 7112 is a piezoelectric ceramic and is annular, which is attached to the outer ring area of ​​the friction layer 7111. The central area 71111 of the friction layer 7111 has multiple micropores 71113 to form a mesh structure.

[0082] Preferably, the friction layer 7111 has a diameter of 10-20 mm, its central region 111 has a diameter of 1-10 mm, and the number of micropores 71113 is 500-5000. These micropores 71113 are extremely small. In the present invention, the size of the micropores 71113 is less than 10 μm, and preferably, the opening size is less than 5 μm. This is because the amount of water anions produced by a tiny droplet is positively correlated with its negative charge density, which in turn depends on the contact time and area with the friction layer 7111, as well as the charge density of the friction layer 7111. Therefore, the smaller the droplet size, the higher its average charge density, and thus the greater the amount of water anions produced. In other words, droplets with smaller diameters are more likely to produce water anions, and the concentration of these anions is higher.

[0083] The friction layer 7111 is configured to vibrate and impact the liquid in the friction liquid storage channel 7132, thereby generating a scented negative ion water mist. The corresponding elastic buffer element 714 is positioned in contact with the friction layer 7111, so that when the friction layer 7111 vibrates to generate the scented negative ion water mist, it simultaneously impacts the elastic buffer element 714, thereby preventing the friction layer 7111 from impacting the water and generating noise. More specifically, when a voltage of a predetermined frequency and peak value is applied to the piezoelectric ceramic layer 7112 and the friction layer 7111, the friction layer 7111 generates high-frequency vibrations that strike the elastic buffer element 714, causing the water between the elastic buffer element 714 and the friction layer 7111 to resonate and generate tiny droplets. As these droplets are generated, they rub against the friction layer 7111 at a high frequency, further acquiring a negative charge and mixing with aroma molecules to form a scented negative ion water mist, which then diffuses into the environment through the micropores 71113. The fan unit 730 blows out air and carries the negative water ions released from the micropores 71113 to diffuse into the vehicle interior environment, thereby increasing the migration distance of the negative water ions.

[0084] The elastic buffer element 714 is made of an elastic material, such as elastic silicone or elastic rubber, and is implemented as an elastic buffer sleeve in the embodiment of Figures 13 to 15, which includes an annular fixing layer 7141, a buffer layer 7142 and a connecting layer 7143. The buffer layer 7142 extends inwardly and integrally through the connecting layer 7143 to the annular fixing layer 7141. The friction mechanism 711 is buried in the elastic buffer element 714. The position of the buffer layer 7142 corresponds to the central area 71111 of the friction layer 7111 having multiple micropores 71113. In this way, when the friction layer 7111 vibrates at high frequency, the central area 71111 having multiple micropores 71113 correspondingly impacts the buffer layer 7142, thereby buffering the vibration of the friction layer 7111 and reducing the noise when hitting the liquid.

[0085] It is understandable that, as shown in FIG. 12 , according to another modified embodiment, the elastic buffer element 714 may also be implemented as an elastic water-absorbing body placed in the liquid storage channel 7132 , such as an elastic cotton swab, sponge, or other water-absorbing elastic material.

[0086] As shown in Figures 10 and 11, in addition, the vehicle-mounted water negative ion aromatherapy device of the present invention may also include a charging device 750, which is a high-voltage discharge module, and its driving voltage can be increased to preferably above -4kV to charge the aromatherapy negative ion water mist generated by the friction mechanism 711, that is, the electrons generated by the charging needle are promptly absorbed by the water mist generated by the friction mechanism 711, thereby generating aromatherapy negative ion water mist rich in negative ions.

[0087] The friction layer 7111 of the vehicle-mounted water negative ion aromatherapy device charges the atomized droplets through triboelectric charging. This allows the negative charges generated by the charging device 750 to more easily adsorb onto the aromatherapy negative ion water mist, thereby increasing the concentration of negative charges adsorbed by the water ions and making it easier for the negative charge to be saturated. In other words, the vehicle-mounted water negative ion aromatherapy device of the present invention not only atomizes the droplets but also charges the atomized water mist itself with negative ions, thereby forming an aromatherapy negative ion water mist. This makes it easier for negatively ionized water molecules to adsorb the negative charges added by the charging device. As a result, compared to simply charging the atomized, uncharged droplets, the already charged aromatherapy negative ion water mist of the present invention is more easily charged, resulting in water negative ions with a higher negative ion concentration.

[0088] In the present invention, the charging device 750 is arranged between the two friction mechanisms 711, so that the aromatherapy negative ion water mist generated by the two friction mechanisms 711 can be supplemented with electric charge to produce high-concentration water negative ions. Therefore, compared with the negative ion generating equipment in the prior art, the vehicle-mounted water negative ion aromatherapy device of the present invention can produce higher concentrations of water negative ions.

[0089] The housing 740 of the vehicle-mounted water negative ion aromatherapy device of the present invention is elongated, and preferably, in this embodiment, is cylindrical. The housing 740 includes a housing body 741 and a base 742. The housing body 741 is cylindrical and is disposed on the base 742, with an air inlet channel 743 formed therebetween. The housing 740 has an outlet 744 on the lateral surface. The aromatherapy negative ion water mist generating unit 710 and the fan unit 730 are disposed within the housing body 741 of the housing 740. The fragrance liquid supply cavity 720 is disposed at the top of the housing body 741 of the housing 740. The fragrance liquid supply cavity 720 can be formed by the top of the housing body 741 of the housing 740, or it can be an independent box and mounted on the housing body 741 of the housing 740.

[0090] As shown in Figures 10 and 11, in this embodiment of the present invention, the air inlet channel 743 is arranged on the bottom side of the shell 740 and is located below the fan unit 730, so that the fan unit 730 draws air into the interior of the portable water negative ion generating device from the air inlet channel 743 of the bottom part of the shell body 741 of the shell 740, and blows it out from the outlet 744 on the side of the shell 740, thereby blowing the water negative ions generated by the aromatherapy negative ion water mist generating unit 710 and the charging device 750 out of the vehicle-mounted water negative ion aromatherapy device from the outlet 744.

[0091] In the present invention, the position of the air inlet channel 743 on the bottom side of the shell 740 means that the air inlet channel 743 is set below the middle of the shell 740, so that the wind enters the shell 740 from the lower end of the shell 740 and then moves upward to reach the aromatherapy negative ion water mist generating unit 710.

[0092] The fan unit 730 includes a fan 731 and a filter 732 , wherein the fan 731 is located above the filter 732 , so that the air entering the housing 740 passes through the filter 732 and then is sent to the aromatherapy negative ion water mist generating unit 710 through the fan 731 .

[0093] It can be understood that in order to facilitate the compact structural design of the vehicle-mounted water negative ion aromatherapy device, the air inlet channel 743 is set at the lower side of the shell 740, and the wind reaches the fan unit 730 from the bottom to the top, and continues to diffuse upward toward the aromatherapy negative ion water mist generating unit 710 after passing through the fan unit 730, and finally turns horizontally and leaves the vehicle-mounted water negative ion aromatherapy device horizontally through the outlet 744 on the side of the shell 740.

[0094] Accordingly, in the vehicle-mounted water negative ion aromatherapy device of the present invention, the fragrance liquid supply cavity 720 is arranged on the top side of the shell 740, and then the fragrance negative ion water mist generating unit 710 and the charging device 750 are arranged in sequence from top to bottom, and then the fan unit 730, so that the vehicle-mounted water negative ion aromatherapy device can be arranged in a miniaturized structure.

[0095] The vehicle-mounted negative water ion aromatherapy device of the present invention is provided with an attachment device 745 on the housing 740, which can be used to secure the device inside the vehicle. This attachment device can be implemented as a clip device, as shown in Figures 9 and 10, for securing to the vehicle's dashboard, air conditioning vent grille, or to a mounting rod under the headrest. Alternatively, as shown in Figure 12, the attachment device 45 can be a suction cup device, allowing the vehicle-mounted negative water ion aromatherapy device to be placed on a flat surface on the vehicle's dashboard.

[0096] The attachment device can be a snap-on device, a magnetic device, an elastic band, or the like, as long as it allows the vehicle-mounted negative water ion aromatherapy device to be detachably mounted on the vehicle. This design makes installation of the device more convenient, allowing users to flexibly install it according to their needs without requiring modifications to the vehicle. Furthermore, it is easy to disassemble, assemble, and carry, and it is also convenient to add fragrance solution to the fragrance solution supply cavity 720, thereby ensuring continuous use of the vehicle-mounted negative water ion aromatherapy device.
